Detailed Description

The following description of the embodiments of the present utility model will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other. Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout.

Examples

Referring to fig. 1-3, the present embodiment provides a drilling and anchoring integrated machine, which includes a chassis 1, a drilling arm 2 and two anchor arms 3.

Referring to fig. 4 and 5, specifically, the bases of the rock drilling arms 2 are disposed on the center line of the chassis 1, and the bases of the two anchor arms 3 are disposed on two sides of the rock drilling arms 2 and slightly rearward.

When in actual use, the bored pile anchor all-in-one machine is operated through the remote controller, and an operator stands on the ground in the tunnel.

The chassis 1 may be a wheel type, a crawler type or a guide rail type according to specific working conditions, and the utility model is not limited thereto, for example, the wheel type chassis 1 is adopted in the embodiment.

The end of the rock arm 2 is fitted with a drilling device 21, which drilling device 21 is intended to drill holes in the rock wall in accordance with a preset position. The drilling device 21 generally comprises a drilling machine 22 and a track 23, and in operation, the drilling machine 22 pushes a drill rod to push forward along the track 23 so as to complete the drilling operation. After drilling is completed, the drill 22 returns. Of course, the drilling device 21 must also include other structures or connection relationships of driving, transmission, control, etc., and the drilling device 21 of the present utility model adopts the prior art, and will not be described herein.

In particular, the utility model optimizes the mounting orientation of the drilling device 21, i.e. the working surface of the rail 23, which is the side of the rail 23 on which the drilling machine 22 is mounted, is arranged towards the side of the apparatus. This arrangement is convenient for the constructor to observe the working condition of the drilling machine 22 in real time, and because the constructor generally stands on one side of the equipment when operating remotely, the above arrangement can make the constructor easily see the working condition of the drilling machine 22.

In the present embodiment, the drilling boom 2 comprises a drilling turret 24, a large drilling boom 25 and a telescopic drilling boom 26.

The rock drilling rig 24, i.e. the base of the rock drilling boom 2, is mounted horizontally rotatably on the chassis 1. The large arm 25 for drilling is connected to the drilling turntable 24 in a pitching manner up and down, specifically, the large arm 25 for drilling comprises two connecting seats 251 and four connecting rods 252 connected between the two connecting seats 251, the connecting seats 251 and the connecting rods 252 form a four-connecting-rod structure together, and the large arm is driven by a large arm driving oil cylinder 27 to pitch up and down relative to the chassis 1.

The drilling telescopic arm 26 is connected to the end of the drilling boom 25 in a manner of pitching up and down, specifically, the rear end of the drilling telescopic arm 26 is connected to a connecting seat 251 of the drilling boom 25, and the drilling telescopic arm 26 has a multi-stage sleeve structure, which is not described in detail in the present utility model. The large drilling boom 25 is used to raise the starting level of the telescopic drilling boom 26. Of course, the jack-up arm 26 is up and down pitched by a jack-up jack 261.

The present embodiment provides the advantage of the large arm 25 for rock drilling: when facing a three-step construction scene in a tunnel, the working arm with the large arm can easily cross the step to convey the tail end to a working point, and the working arm without the large arm is blocked by the step, so that the applicability and the convenience of the application can be improved.

In the present embodiment, the front end of the drilling telescopic boom 26 is connected with a drilling boom 28 and a swing seat 29 in order.

Specifically, the arm 28 is a U-shaped member, which opens forward, and the rear upper end of the U-shaped member is horizontally pivoted to the end of the telescopic arm 26, so that the arm 28 can swing up and down around the pivot. A boom cylinder (not shown) is connected between the drilling boom 28 and the drilling telescopic boom 26 for driving the drilling boom 28 to pitch up and down. The arm 28 is provided with a sensor (not shown) for detecting the levelness of the arm 28 in real time, and transmitting a detection signal to the controller, so as to control the arm cylinder to return the arm 28 to a horizontal state, and the sensor is used for ensuring that the arm 28 can always maintain the horizontal state when moving along with the telescopic arm 26.

The swing seat 29 is connected to the drilling boom 28 by means of a vertical pivot 211, so that the swing seat 29 can swing horizontally with respect to the drilling boom 28. The middle part of the drilling device 21 is connected to the front end of the swinging seat 29 through a horizontal pivot 212, so that the whole drilling device 21 can rotate 360 degrees relative to the swinging seat 29. By arranging the swinging seat 29, the horizontal pivot 212 can be always parallel to the main axis of the tunnel (the extending axis of the tunnel) before the drilling position is adjusted, so that the vertical working surface of the drilling device 21 can be conveniently and rapidly controlled, and the working efficiency is improved.

It should be noted that, the vertical pivot 211 and the horizontal pivot 212 are driven by a belt, such as a motor, a hydraulic motor, etc., so that a rotation function can be achieved.

The drilling device 21 can be flexibly moved to the working point for drilling operation under the drive of the rock drilling arm 2. Of course, in other embodiments, the drilling arm 2 may also comprise only telescopic arms, but it is not so easy to deal with when facing a three-step construction scenario.

Referring to fig. 6-13, in the present embodiment, the anchor arm 3 includes a second turntable 31 and an anchor telescopic arm 32, where the second turntable 31 is a base of the anchor arm 3, and the anchor telescopic arm 32 is also a multi-stage sleeve structure, which is not described herein. The rear end of the anchor telescopic arm 32 is pivoted on the second turntable 31, and an anchor driving oil cylinder 33 is arranged between the anchor telescopic arm 32 and the second turntable, and the anchor driving oil cylinder 33 is used for driving the anchor telescopic arm 32 to perform pitching motion up and down relative to the chassis 1.

Further, the front end of the anchor telescopic arm 32 is sequentially connected with an anchor arm 34 and a working platform 4, and the working platform 4 is horizontally rotatably mounted at the tail end of the anchor arm 34. Of course, the rotation angle of the work platform 4 is adjustable and can be positioned at any angle. The outside of the working platform 4 is provided with an anchor loading device 35, and the anchor loading device 35 is an assembly for completing anchor rod installation.

Specifically, the anchoring small arm 34 is L-shaped, the rear end of the anchoring small arm 34 is horizontally pivoted to the front end of the anchoring telescopic arm 32, a driving oil cylinder (not shown) is arranged between the anchoring small arm 34 and the anchoring telescopic arm 32, and a sensor (not shown) is arranged on the anchoring small arm 34 and used for being matched with a controller to enable the front end of the anchoring small arm 34 to keep a horizontal state in the pitching process. The mechanism of the cooperation of the sensor and the driving oil cylinder can ensure that the working platform 4 always keeps a horizontal state in the moving process of the anchor telescopic arm 32. Meanwhile, the horizontal pivot 212 of the anchor loading device 35 is ensured to be always kept horizontal, the initial posture of the anchor loading device 35 is simplified, and posture adjustment of the anchor loading device 35 is facilitated.

It should be noted that in other embodiments, the anchor arm 3 may be arranged to comprise a large arm as the drilling arm 2, as well, which the utility model is not limited to. The combination of the drilling arm 2 and the anchoring arm 3 in this embodiment is undoubtedly the combination which is the simplest in construction, the lowest in cost and the most suitable for anchoring and supporting.

In this embodiment, the axial length of the drilling device 21 is about 7 meters, and the axial length of the anchor device 35 is about 4 meters. The axial length of the anchor loading device 35 is set to be smaller than that of the drilling device 21, so that the whole machine can move more agilely in the limited space of the tunnel, and the condition that two working arms interfere with each other is avoided; ideally, the drilling device 21 and the two anchor devices 35 can work simultaneously, so that the construction efficiency is greatly improved. Because the whole length of the drilling and anchoring device in the prior art is longer, the drilling and anchoring devices on the two telescopic arms cannot work simultaneously.

According to the utility model, the method of the multifunctional arm of the prior equipment is changed, the drilling function and the anchor loading function are split and are respectively configured on the two working arms, so that the two working arms can respectively and independently complete the functions, namely, the drilling arm 2 is focused on drilling and the anchor loading arm 3 is focused on anchor rod installation, the drilling arm 2 can carry out anchor loading operation while drilling, the situation that the drilling and anchor loading are completed in tandem as in the prior art is avoided, and the utility model has no neutral position in time utilization and is independent in space, thereby being beneficial to improving the construction efficiency; the structure that the drilling function and the anchor loading function are respectively arranged on the two working arms enables the anchor loading device 35 to obtain more installation space and more movable space, and provides conditions for expanding the anchor loading function, such as adapting more types of anchor rods, performing more complex anchor rod installation processes and the like.

Because the two functions of drilling and anchoring are split, one problem which the utility model must solve is that: how the anchor arm 3 can find the position and orientation of the hole and complete the anchor rod installation.

Referring to fig. 15, in one embodiment, the present utility model further includes a controller, a plurality of first position sensors, and a plurality of second position sensors. The controller can be a controller integrated in a whole vehicle control system or a distributed controller. The first and second position sensors are mounted on the rock drilling arm 2 and the anchor arm 3, respectively. Specifically, the mounting positions of the sensors are joint positions of the working arms and important parts, and are used for recording the rotation angle, the up-down pitching angle, the telescopic length, the left-right swinging angle and the like of the working arms; hole site information for each hole is recorded with a first sensor, the hole site information including the position of the hole and the orientation of the hole, and the formation number is stored in the controller.

The two ends of the outer telescopic rod 372 and the inner telescopic rod 373 are respectively connected, so that when the length of the warehouse rack 371 is adjusted, only the outer telescopic rod 372 needs to be adjusted, the inner telescopic rod 373 can synchronously stretch, and the length of the warehouse rack 371 is adjusted. The stock 371 of the present embodiment can be extended and shortened, so that it can be adapted to anchors of almost all length sizes on the market, and thus stably store the anchors.

Specifically, one end of the base 371 is further provided with a driving device (not shown) for driving the inner telescopic rod 373 to rotate around its axis, thereby driving the anchor rod thereon to rotate.

More specifically, the stock 371 further includes a drop rod ring 375, the drop rod ring 375 surrounds the stock 371, and the drop rod ring 375 is a ring with a notch. The notch is downward, and when interior telescopic link 373 rotated and drove one of them stock just to this notch, the stock has the trend that drops downwards under the effect of gravity.

In this embodiment, the outer telescoping rod 372 includes an inner tube 3721, a sleeve 3722, and a locking member 3723. The inner tube 3721 and the sleeve 3722 are sleeved with each other and can relatively stretch back and forth, and the locking member 3723 is arranged between the inner tube 3721 and the sleeve 3722 for positioning between the two.

The conveying wheel 3921 is also connected with a hydraulic motor 3925 for driving the conveying wheel 3921 to rotate. Of course, in other embodiments, a motor or the like may be used to drive the conveying wheel 3921 to rotate. Preferably, in order to facilitate the anchor rod to be clamped between the edges of the two conveying wheels 3921 more accurately and smoothly, a guide piece 3926 can be further arranged, the guide piece 3926 is fixed on one of the conveying wheels of the swing arm 3923 and is provided with a horizontal slot, the horizontal slot is as high as the edge of the conveying wheel 3921, and when the two conveying wheels 3921 are closed and clamped, the horizontal slot of the guide piece 3926 guides the anchor rod to enter between the two conveying wheels 3921 in a homeotropic manner, so that accurate and smooth clamping is ensured.

The conveyor wheel assembly 392 operates as follows:

When the two swing arms 3923 are close to each other, the two conveying wheels 3921 are also close to each other; the rims of the transfer wheels 3921 are arranged to be recessed inward, and the rims of the two transfer wheels 3921 form a position for holding the anchor rods. Under the action of the hydraulic motor 3925, the conveying wheels 3921 rotate, so that the purpose of clamping the anchor rod and driving the anchor rod to convey forwards is achieved.

It should be noted that, the conveying structure of the conveying wheel assembly 392 not only can realize the conveying of the rigid anchor rod, but also can realize the conveying of the anchor cable, thereby improving the range of the adaptable anchor rod of the utility model.

The buffer spring 396 is arranged in the application, so that the situation is effectively avoided, the purposes of releasing extrusion force and protecting structural members can be achieved, and the service life of the equipment is prolonged.

More optionally, the tail end of the torsion bar 3942 is further sleeved with a sleeve, two ends of the buffer spring 396 respectively prop against the torsion bar 3942 and the sleeve 397, and the sleeve 397 can rotate relative to the housing 395. After assembly, the sleeve 397 can rotate together with the buffer spring 396 and the torsion bar 3942, so that the buffer spring 396 is prevented from directly acting on the shell seat 395, and the function of the shell seat 395 can be realized.

As a further improvement, referring to fig. 13, a translation mechanism (not labeled in the figure) is further provided between the rotary pushing assembly 393 and the slider (not shown) on the anchor rail 391; the translation mechanism is used to move the rotary pushing assembly 393 back and forth in the lateral direction (perpendicular to the axis of the torsion tube 3941). For example, a structure such as a slide plate, a slide rail, a screw rod and the like is arranged between the two; or a swing frame is arranged on the anchor rail 391, the rotary pushing assembly 393 is fixed on the swing frame, and the rotary pushing assembly 393 moves back and forth in the transverse direction through left and right swinging. Any structure capable of realizing the transverse back and forth movement of the rotary pushing assembly 393 on the anchor rail 391 is not limited in this disclosure. It should be noted that, the translation direction of the translation mechanism is preferably perpendicular to the extending direction of the anchor rail 391 (the axis of the torsion tube 3941), and the technical effect that the anchor rail 391 avoids the anchor rod (when the conveying wheel assembly conveys the anchor rod) can be achieved as long as the translation direction is not parallel to the extending direction of the anchor rail 391.

Referring to fig. 14 in combination, in this embodiment, the end of the anchor arm 3 is further provided with a working platform 4, the working platform 4 includes a bottom plate 41, a rail 42 and a ceiling 43, the ceiling 43 includes a column and a baffle, the bottom of the column is fixedly connected to one side of the working platform 4, the baffle is fixedly connected to the top end of the column, and the baffle extends into the working platform 4 and covers a middle part area of the working platform, so as to protect the constructor to the maximum extent. The positioning of the work platform 4 on the anchor arm 3 provides the following benefits: the existing work platform 4 is provided on the other work arm separately from the anchor means 35. When the anchor rod installation process fails, the working arm (the arm with the working platform) needs to be controlled to be close to the other working arm (the multifunctional arm and the arm with the anchor installing device), however, in the actual use process, the two working arms cannot be sufficiently close, and particularly the difficulty of approaching the failure places is great, the failures include but are not limited to drilling failures, anchor rod installation failures and the like, and in many cases, workers need to climb out of the working platform 4 to reach the working points, and the working points of the failures often approach to anchor holes very closely, so that the manual auxiliary work is inconvenient and dangerous. The working platform 4 is arranged at the tail end of the anchor loading arm 3, so that the working platform is naturally close to the anchor loading device 35 and the anchor holes being processed, and the auxiliary operation of workers on drilling and anchor rod installation work and the overhauling and the elimination of related faults are facilitated.

As a further improvement, the working platform 4 is of a structure capable of horizontally and transversely expanding, specifically, a pedal 44 capable of turning up and down is arranged on one side surface of the working platform 4, the pedal 44 is turned down and positioned in a horizontal state and can be used as an extension area of the original working platform 4, so that a space capable of being stood by a constructor is expanded; preferably, the pedal 44 is provided with a guard rail 45 for a constructor to walk, thereby improving safety. The pedals 44 are turned upwards to be positioned in a vertical state, and can seal the original working platform 4. A movable connecting piece, such as a clamping hook, is arranged between the pedal 44 and the working platform 4, so that the pedal 44 can be conveniently put down and returned.

Specifically, the anchor 35 is pivotally mounted to the outside of the work platform 4. In a specific installation position, the horizontal pivot of the anchor loading device 35 is positioned in the middle of the working platform 4, so that the anchor loading device 35 can rotate by 360 degrees, and the installation posture can be flexibly adjusted. It should be noted that: in other embodiments, both the anchor device 35 and the work platform 4 may be individually rotatably mounted at the end of the anchor arm 3.

As a further improvement, the end of the anchor arm 3 is also provided with a grouting mechanism 5, which grouting mechanism 5 is in this embodiment mounted in the working platform 4. The grouting mechanism 5 comprises a grouting stirring barrel and a grouting pump, wherein the grouting pump is connected with the anchor device 35 through a pipeline, and particularly is connected with the tail end of the torsion bar 3942.

Such an arrangement provides the following benefits: the scheme of the application actually shortens the distance between the grouting mechanism 5 and the anchor loading device 35, firstly, the length of the pipeline can be reduced, and the cost is reduced; secondly, the power and the volume of the grouting pump can be reduced, and the cost can be reduced; third, shorter tubing may reduce waste of slurry remaining in the tubing.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. For example: the number of the drilling arms 2 can be two, three, etc., and the number of the anchor arms 3 is not limited to two in the above embodiment, for example, only one, three, etc. can be provided, and the manufacturer can flexibly set according to the actual scene in the tunnel and the space condition of the chassis 1. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications of the utility model are intended to fall within the scope of the utility model.
