The end of the anchor drill near the working rock is called the front end, and since the drill rod is mounted in series with the output shaft of the drill motor, the operator can insert the drill rod only at the front end of the anchor drill to perform the work. This design limits the length of the drill rod, and for space reasons, it is not possible to perform one-time operation with a long drill rod, for example, a drill rod 2.3m long needs to be drilled into the rock formation, and only two operations can be performed by dividing the drill rod into a drill rod 1.3m and a drill rod 1 m. Specifically, after the first drill rod is completed, a space is left at a position where the drill motor needs to be retracted, and then the second drill rod is clamped.

Further, the projection of the second mounting hole on the end face of the second shaft is any one of a regular hexagon, a square, a rectangle, or an ellipse. Specifically, when the projection of the second mounting hole on the end surface of the second shaft is a regular hexagon, it can be understood that the second mounting hole of the second shaft is an inner hexagonal hole, the circumferential side wall of the drill rod is an outer hexagonal, and the circumferential rotation of the drill rod can be restricted by setting the second mounting hole to the inner hexagonal hole.

The three-jaw chuck is provided with a limiting hole, the central line of the limiting hole is collinear with the central line of the penetrating hole, and the drill rod penetrates through the limiting hole. The working principle of the three-jaw chuck is that the three movable jaws uniformly distributed on the chuck body move radially, so that the inner diameter of the limiting hole is changed. The three-jaw chuck can limit the drill rod. The three-jaw chuck is arranged at one end of the fixing part close to the drilling machine, so that the moving space between the drilling machine and the working rock stratum can be increased. In addition, after the drill rod is inserted from the rear end, a worker can operate the three-jaw chuck to limit the drill rod in the radial direction at a position as close to the rear end as possible, and the safety performance is improved.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present invention may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

A drill structure 100 and an anchor drill 200 provided in accordance with some embodiments of the present invention are described below with reference to fig. 1-6.

Example one

As shown in fig. 1 and 2, one embodiment of the present invention provides a drill structure 100 comprising a mount 110, a drill 130, and a clamping structure 150. The mount 110 functions as a mounting carrier and the mount 110 in the drill structure 100 is slidably connected to the frame 210 in the anchor drill 200. The drill 130 is provided on the mount 110. The clamping structure 150 includes a fixing portion 142 and a clamping portion 160. Specifically, the fixing portion 142 is rotatably connected to the mounting base 110, i.e., the fixing portion 142 can rotate relative to the mounting base 110. The fixing portion 142 is in transmission connection with the drilling machine 130, and the drilling machine 130 drives the fixing portion 142 to rotate. The fixing portion 142 is provided with a through hole 1421 penetrating the fixing portion 142, and the through hole 1421 is used for mounting the drill rod 300. In other words, the drill rod 300 can be inserted into the insertion hole 1421 of the fixing portion 142. Further, the clamping portion 160 is provided to the fixing portion 142, and the clamping portion 160 can clamp the drill rod 300.

In the related art anchor drilling machine 200 ', as shown in fig. 7, 8, 9, 10, 11 and 12, one end of a drill rod is installed in series with the drilling machine motor 130 ' through a connecting bushing 180 ', and the other end of the drill rod is used to abut against a rock formation. The end of the anchor drill 200 ' near the working rock is referred to as the front end, and since the drill rod is installed in series with the output shaft of the drill motor 130 ', the operator can insert the drill rod only at the front end of the anchor drill 200 ' to perform the work. This design limits the length of the drill rod, and for space reasons, it is not possible to perform one-time operation with a long drill rod, for example, a drill rod 2.3m long needs to be drilled into the rock formation, and only two operations can be performed by dividing the drill rod into a drill rod 1.3m and a drill rod 1 m. Specifically, after the first drill rod is completed, the drill motor 130' needs to be retracted to leave a space, and then the second drill rod is clamped. The forward insertion type clamping drill rod needs to retreat the drill motor 130' every time, the process is complicated, and the efficiency is influenced. In the process of clamping the second anchor rod, the position of the first drill rod is required to be ensured not to move, so that the space for clamping the second drill rod is limited, the drill rod needs to be manually inclined by a certain angle for hole alignment, the operation difficulty is high, and the efficiency is low.

When the driving shaft 131 drives the transmission shaft 122 to rotate, the fixing portion 142 also rotates, and thus the drill rod 300 can be driven to rotate.

Further, the cross section of the insertion hole 1421 is a regular polygon, the cross section of the drill rod 300 has the same shape as the cross section of the insertion hole 1421, and after the drill rod 300 is inserted into the insertion hole 1421 of the fixing portion 142, the insertion hole 1421 can restrict circumferential rotation of the drill rod 300. Further, the projection of the insertion hole 1421 on the end surface of the fixing portion 142 is any one of a regular hexagon, a square, a rectangle, and an ellipse. Specifically, when the projection of the insertion hole 1421 on the end surface of the fixing portion 142 is a regular hexagon, it can be understood that the insertion hole 1421 of the fixing portion 142 is an inner hexagonal hole, the circumferential side wall of the drill rod 300 is an outer hexagonal hole, and the circumferential rotation of the drill rod 300 can be restricted by setting the insertion hole 1421 to the inner hexagonal hole.

The first gear 121 is rotatably disposed on the mounting base 110, and the second gear 141 is rotatably disposed on the mounting base 110. In other words, the first gear 121 is connected to the mounting base 110, and the first gear 121 can rotate relative to the mounting base 110; the second gear 141 is connected to the mounting base 110, and the second gear 141 can rotate relative to the mounting base 110.

In the technical scheme of the application, the drill rod 300 is arranged in the fixing portion 142 in a penetrating manner, so that compared with a mode that the drill rod 300 is directly arranged in the second gear 141 in a penetrating manner, the contact area between the drill rod 300 and the drill rod 300 is increased, the connection strength between the second gear 141 and the drill rod 300 is improved, and the safety performance of the anchoring drilling machine 200 in the working process can be further improved.

Further, the projection shape of the drill rod 300 on the end surface of the fixing portion 142 is the same as the projection shape of the insertion hole 1421 on the end surface of the fixing portion 142, so that the insertion hole 1421 can restrict the circumferential rotation of the drill rod 300 after the drill rod 300 is inserted into the insertion hole 1421 of the fixing portion 142. Further, the projection of the insertion hole 1421 on the end surface of the fixing portion 142 is any one of a regular hexagon, a square, a rectangle, and an ellipse. Specifically, when the projection of the insertion hole 1421 on the end surface of the fixing portion 142 is a regular hexagon, it can be understood that the insertion hole 1421 of the fixing portion 142 is an inner hexagonal hole, the circumferential side wall of the drill rod 300 is an outer hexagonal hole, and the circumferential rotation of the drill rod 300 can be restricted by setting the insertion hole 1421 to the inner hexagonal hole.

Example four

As shown in fig. 2, the drill structure 100 further includes a drive shaft 122. Specifically, the transmission shaft 122 is rotatably connected to the mounting base 110, i.e., the transmission shaft 122 can rotate relative to the mounting base 110. The first gear 121 is sleeved on the transmission shaft 122, and the first gear 121 and the transmission shaft 122 are relatively fixed, it can be understood that the first gear 121 can rotate relative to the mounting base 110 through the transmission shaft 122.

Further, the drilling machine 130 is disposed on one side of the mounting base 110, and specifically, the drilling machine 130 is disposed on one side of the mounting base 110 away from the working rock formation. Specifically, the drilling machine 130 has a rotatable drive shaft 131, and during operation, the drive shaft 131 in the drilling machine 130 can rotate. One end of the driving shaft 131 extends into the mounting hole 1221 of the transmission shaft 122 to realize the relative fixation of the driving shaft 131 and the transmission shaft 122, the driving shaft 131 can drive the transmission shaft 122 to rotate, and in the rotating process of the transmission shaft 122, the driving shaft can drive the first gear 121 to rotate, and then the first gear 121 drives the second gear 141 to rotate.

EXAMPLE five

As shown in fig. 2, the clamping portion 160 is a three-jaw chuck. Specifically, the three-jaw chuck is disposed at an end of the fixing portion 142 near the drilling machine 130, i.e., at an end of the fixing portion 142 away from the working rock. The three-jaw chuck is provided with a limiting hole 161, the central line of the limiting hole 161 is collinear with the central line of the penetrating hole 1421, and the drill rod 300 penetrates through the limiting hole 161, so that the axes (or central lines) of the drill rod 300, the penetrating hole 1421 and the limiting hole 161 coincide after a worker penetrates the drill rod 300 into the penetrating hole 1421. The working principle of the three-jaw chuck is that the three movable jaws uniformly distributed on the chuck body move in the radial direction, so that the inner diameter of the limiting hole 161 is changed. The three-jaw chuck can limit the drill rod 300. By providing a three-jaw chuck at the end of the fixed portion 142 near the drill 130, the active space between the drill 130 and the working formation may be increased. In addition, after the drill rod 300 is inserted from the rear end, a worker can operate the three-jaw chuck to limit the drill rod 300 in the radial direction at a position as close to the rear end as possible, and the safety performance is improved.

Further, as shown in fig. 2, the drill structure 100 further includes a swivel 170. Specifically, the rotary joint 170 is rotatably disposed on a side of the clamping portion 160 away from the fixing portion 142, and it is understood that the rotary joint 170 is disposed on an end of the drilling machine structure 100 away from the working rock, and the rotary joint 170 can rotate relative to the clamping portion 160. Further, as shown in fig. 3, the rotary joint 170 is connected to the drill rod 300, the rotary joint 170 is provided with a first water passage hole 171, the drill rod 300 is provided with a second water passage hole 310, and the length direction of the second water passage hole 310 coincides with the length direction of the drill rod 300. The anchoring drill 200 further includes a water pipe having one end connected to the rotary joint 170 and communicating with the first water passage hole 171 of the rotary joint 170, and the first water passage hole 171 of the rotary joint 170 and the second water passage hole 310 of the drill rod 300. In other words, the water in the water pipe may sequentially pass through the first water passing hole 171 and the second water passing hole 310, and finally flow to the end of the drill rod 300 away from the drilling machine 130, so as to remove a part of the crushed stones on the working surface by the water flow, which is beneficial to smoothly performing the drilling work.

EXAMPLE six

As shown in fig. 2, the mount 110 includes a gear case 111, a first rolling bearing 112, a second rolling bearing 113, a third rolling bearing 114, and a fourth rolling bearing 115. Specifically, the gear box 111 is a main body part of the mounting base 110, and the gear box 111 is covered outside the first gear 121 and the second gear 141, that is, the first gear 121 and the second gear 141 are both arranged in the gear box 111. Further, a first rolling bearing 112, a second rolling bearing 113, a third rolling bearing 114, and a fourth rolling bearing 115 are provided in the gear case 111, that is, four rolling bearings are provided in the gear case 111. Further, the first rolling bearing 112 is disposed on one side of the first gear 121, the second rolling bearing 113 is disposed on the other side of the first gear 121, and the transmission shaft 122 is disposed through the first rolling bearing 112 and the second rolling bearing 113. It is understood that the transmission shaft 122 is rotatable relative to the gear box 111 via the first rolling bearing 112 and the second rolling shaft. Since the first gear 121 and the transmission shaft 122 are relatively fixed, the transmission shaft 122 can drive the first gear 121 to rotate.

Further, the third rolling bearing 114 is provided on one side of the second gear 141, the fourth rolling bearing 115 is provided on the other side of the second gear 141, and the fixing portion 142 is supported by the third rolling bearing 114 and the fourth rolling bearing 115. It is understood that the fixing portion 142 is rotatable relative to the gear case 111 by the third rolling bearing 114 and the fourth rolling bearing 115.

It is to be noted that the first rolling bearing 112 and the second rolling bearing 113 are both deep groove ball bearings. Of the third rolling bearing 114 and the fourth rolling bearing 115, the distance between the third rolling bearing 114 and the three-jaw chuck is shorter, that is, the third rolling bearing 114 is closer to the three-jaw chuck. The third rolling bearing 114 is a self-aligning roller bearing, and the fourth rolling bearing 115 is a deep groove ball bearing. In addition, by providing one rolling bearing on each of both sides of each gear, the sliding friction between the shaft and the gear case 111 can be changed to rolling friction, thereby reducing the friction loss.

Further, as shown in FIG. 2, the gearbox 111 includes a first end cap 116 and a second end cap 117. Specifically, the first end cap 116 and the second end cap 117 are disposed along an axial direction of the installation shaft, and the installation shaft penetrates through the first end cap 116 and the second end cap 117. The first end cover 116 is located on the side of the gear box 111 away from the drill 130, and the second end cover 117 is located on the side of the gear box 111 close to the drill 130. The third rolling bearing 114 and the fourth rolling bearing 115 are both located between the first end cap 116 and the second end cap 117, and of the third rolling bearing 114 and the fourth rolling bearing 115, the third rolling bearing 114 is closer to the first end cap 116, and the fourth rolling bearing 115 is closer to the second end cap 117. A first oil sealing structure 1181 is arranged between the first end cover 116 and the third rolling bearing 114, and a second oil sealing structure 1182 is arranged between the second end cover 117 and the fourth rolling bearing 115. It is worth mentioning that an oil seal structure may be understood as a seal.

Further, the mounting base 110 further includes a mounting frame 119. Specifically, a mounting bracket 119 is provided at the bottom of the gear box 111, and the mounting bracket 119 is slidably coupled to a frame body 210 of the anchor drill 200. It can be understood that the mounting block 110 slides relative to the frame body 210 through the mounting frame 119, and since the drill rod 300 is inserted into the insertion hole 1421 of the mounting block 110, the position of the drill rod 300 can be adjusted by changing the position of the mounting block 110.

EXAMPLE seven

As shown in fig. 4 and 5, an anchoring drill 200 according to an embodiment of the present invention includes a frame body 210 and a drill structure 100. Specifically, the mounting block 110 of the drilling machine structure 100 is slidably connected to the frame body 210, that is, the mounting block 110 can slide relative to the frame body 210, and the drill rod 300 can be drilled into the working rock formation by continuously pushing the position of the mounting block 110. The worker can clamp the drill rod 300 from the rear end of the anchoring drilling machine 200, which is beneficial to increasing the installation space for clamping the drill rod 300 and can realize the one-time operation of the longer drill rod 300.

Further, as shown in fig. 4, 5 and 6, the anchoring drill 200 further includes a gripper 220. The holder 220 is provided at one end of the frame body 210, and in particular, the holder 220 is provided at one end of the anchor drill 200 adjacent to the working rock formation. The drill rod 300 in the drilling machine structure 100 is inserted into the holder 220, and the drill rod 300 can rotate relative to the holder 220. Depending on the job requirements, the crew sometimes drills the shank 300 into two sections sequentially into the formation. After the first section of drill rod 300 is drilled into the rock formation, the first section of drill rod 300 is clamped by the clamp 220, the first section of drill rod 300 is limited, and then a worker inserts the second section of drill rod 300 into the penetrating hole 1421 of the fixing part 142 from the rear end of the anchoring assembly and connects the two sections of drill rods 300.

According to the drilling machine structure and the anchoring drilling machine, the penetrating holes are formed in the fixing parts, so that a worker can clamp the drill rod from the rear end of the anchoring drilling machine, on one hand, the mounting space for clamping the drill rod is increased, and one-time operation of a longer drill rod can be realized; on the other hand, the number of times of the backward movement of the drilling machine can be reduced, the operation is convenient, the working process is simplified, the working difficulty is reduced, and the working efficiency can be improved.
