Description

Guide sliding sleeve device for lifting cage and rope cage shoe

Technical Field

The utility model relates to a promote cage and use direction sliding sleeve device, the utility model discloses still relate to one kind and possess the rope cage shoe that promotes cage and use direction sliding sleeve device.

Background

For example, in a mine, a coal mine, or other places having a shaft, it is often necessary to provide a container for transporting personnel or equipment. The lifting container needs to be kept stable during lifting, avoiding rotation and collision with the well wall, and therefore, the lifting container needs to be provided with a guide device besides a lifting device.

There are four types of guide devices (square wooden guide, steel rail guide, combined rigid guide, and wire rope guide) that are suitable for hoisting containers such as cages, and two types of guide devices are commonly used, one type is a steel guide type rigid guide (steel rail guide) for a vertical shaft, and the other type is a flexible guide (wire rope guide) such as a wire rope guide that can be used for a vertical shaft or an inclined shaft. The flexible cage guide generally adopts four steel wire ropes as guide ropes (generally called cage guide ropes), and four corners of the flexible cage guide are respectively provided with one steel wire rope corresponding to the lifting container. The upper end of the cage guide rope is fixed on the derrick, and the lower end of the cage guide rope adopts a connecting device and is tensioned by a heavy hammer, a hydraulic device or other tensioning devices.

Because the cage functioning speed is higher, will guarantee cage operation safety, should minimize the wearing and tearing to the direction rope in operation, for the direction rope, sliding sleeve hardness will be low, and the direction rope itself has wear-resisting, easily changes and extremely low characteristics to the wearing and tearing of direction rope concurrently simultaneously.

One of the common knowledge in the mechanical field is that under otherwise identical technical conditions, the friction coefficient of rolling friction is lower than that of sliding friction, and therefore, the rolling friction is also used in the field to directly replace sliding sleeves to reduce the abrasion of steel wire ropes. Typically, as in chinese patent document CN201024028Y, a flexible guide device for a shaft guide is disclosed, which comprises an inner support, an outer support, and three guide wheels mounted on the inner support, wherein the three guide wheels are arranged in a triangular shape around the circumference of a steel cable. The structure can effectively reduce the friction coefficient, however, the guide contact position provided by the guide wheel is in a linear shape, the contact area is small, and the guide stability is relatively poor. In addition, the three guide wheels are at least provided with six bearings, and the bearing efficiency probability is greatly increased in high-speed operation. The losses of the six bearings are different, and once one bearing has a problem, other bearings can also fail in a short time due to the increase of additional load, so that the overall cost is high, and the maintenance is inconvenient.

Similarly, under the condition that the sliding friction cannot be changed to the rolling friction, a method for further improving the friction condition is to apply a friction agent to the friction interface. For example, chinese patent document CN203877688U discloses a self-lubricating rope can, which includes a sliding sleeve cover and a sliding sleeve seat, an inner cavity is formed between the sliding sleeve cover and the sliding sleeve seat, a sliding sleeve composed of two half sliding sleeves with semicircular sections is disposed in the inner cavity, a groove is disposed in the inner cavity wall of the half sliding sleeve, and lubricating grease is filled in the groove. Different from other types of lubricating structures, the steel wire rope is relatively long, the surface of the steel wire rope is provided with the rope grains, a gap is inevitably formed between the steel wire rope and the sliding sleeve, in other words, a good sealing effect cannot be achieved between the sliding sleeve and the steel wire rope, in addition, the rope grains are arranged on the steel wire rope, more lubricating grease is easily embedded, the lubricating grease is quickly used up in the relative motion of the steel wire rope and the sliding sleeve, or the lubricating grease is reserved on only a part of the shorter steel wire rope. Most of the exposed lubricating grease is accommodated in the rope threads, so that the anti-friction effect cannot be achieved, and on the other hand, in working occasions such as mines and the like, the environment is severe, and the exposed lubricating grease is very easy to be polluted and quickly fails.

Detailed Description

Referring to fig. 1 and 2, the base 2 is a substantially square block structure which is mainly used to provide a seat hole and for installing a guide sliding sleeve device for a lifting cage on a lifting container, and obviously, the axial direction of the seat hole is the direction of a guide rope or a cage guide rope.

In fig. 1, four fixing holes are formed on the base 2, and can be fixed on the lifting container by using screws or bolts.

It is also possible to mount the base 2 on the lifting container, for example by welding, in that the base 2 is not susceptible to failure, and it is a sliding sleeve that is relatively susceptible to failure.

As a guide sliding sleeve device for a lifting cage, the guide sliding sleeve device comprises a sliding sleeve and a base 2, wherein the sliding sleeve is fixed on the base 2 in a mosaic or welding mode in the traditional application and is difficult to replace, so other modes have to be implemented to reduce the loss of the sliding sleeve.

In the embodiment of the utility model, adopt the technical route of ball similar to ball-point pen, under the relatively short condition of ball life-span, no longer as the spare part, but as the consumptive material together with the refill.

Furthermore, in the embodiment of the utility model, the sliding sleeve is found to the material that available hardness is lower relatively, and alleviates wire rope's loss, based on changing the convenience, improves the maintainability of rope cage guide.

Compared with a roller pair, the traditional sliding sleeve has the advantages that the provided friction surface is large, and the stability of the rope guide is better. However, since the contact surface is large, the probability of failure thereof becomes large. In contrast to improving the life of the sliding sleeve, in the embodiment of the invention, a route which is easy to replace is adopted instead of a route which sacrifices the running stability of the rope cage guide.

Regarding the base 2, the shape is not limited to the shape of the base 2 shown in fig. 1 and 2, obviously, as long as it can provide a seat hole for installing a sliding sleeve, and in addition, the seat hole is not limited to be a whole hole, and it can also be represented by a multi-stage hole with the same coaxial line and the same hole diameter.

Unlike a simple circular hole, in fig. 2, the upper side of the seat hole is cut away or directly formed integrally with the seat body of the base 2, for example, by casting. The through groove 24 is through the seat hole in the axial direction, and the through groove 24 is through in the radial direction at the side of the seat hole where the through groove 24 is located.

In fig. 2, the opened groove 24 is a rectangular through groove on the end face side (base of the seat hole end) of the base 1, and obviously is not limited to the rectangular through groove, depending on the shape of the sub-flange 15 shown in fig. 3.

For the sliding sleeve, the sliding sleeve is formed by folding two half sliding sleeves 1, and the folding needs to be locked by using a seat hole. Furthermore, the sliding sleeve matched with the shaft hole between the seat holes is formed by folding the two half sliding sleeves 1 and is locked by being bound by the seat holes, and the sliding sleeve and the seat holes are in clearance fit or transition fit, mainly in clearance fit, so that the half sliding sleeves 1 can be conveniently inserted or taken out.

In addition, in some embodiments, an interference fit can be used to ensure the tightness of the involution, during the interference fit, the base 2 needs to be heated in advance by a proper amount, such as oil immersion, water immersion or heating in a heat preservation furnace, so as to enlarge the aperture of the seat hole, facilitate the assembly, and after natural cooling, the seat hole can tighten the involution half sliding sleeve 1.

For clearance fit or transition fit, lubricating oil or lubricating grease can be coated on the seat hole or the matching surface of the half sliding sleeve 1 and the seat hole during assembly, so that the assembly and the adjustment after the assembly are convenient.

Furthermore, one end of the half sliding sleeve 1 is provided with a first limiting part which can axially pass through the through groove and axially limit one end of the seat hole after the sliding sleeve rotates for a given angle, such as an auxiliary flange 15 shown in fig. 3 and 4, the auxiliary flange can move towards one end of the seat hole along with the sleeve body 12 of the half sliding sleeve 1 through the through groove 24, after the auxiliary flange 15 penetrates out of the seat hole, the half sliding sleeve 1 is rotated for a certain angle, the auxiliary flange 15 avoids the through groove 24, and therefore the half sliding sleeve 1 is blocked based on the auxiliary flange 15.

In fig. 1, the secondary flange 15 is turned 90 degrees just after being axially fitted in place along the seating hole. It should be noted that, because another half of the sliding sleeve 1 needs to be assembled, the auxiliary flange 15 installed first needs to be rotated 180 degrees first, and after the other half of the sliding sleeve 1 is axially assembled in place, the formed sliding sleeve is rotated 90 degrees again to be in place.

Correspondingly, the other end of the half sliding sleeve 1 is provided with a second limiting part for axially limiting the other end of the seat hole, such as a main flange 11 shown in fig. 3, and the main flange 11 is limited at the other end of the seat hole.

After the two sliding sleeves 1 are assembled in place, the sliding sleeves are rotated to an angle suitable for limiting one end of the seat hole to the auxiliary flange 15, and then the sliding sleeves are locked by using a locking component, namely the locking is on the base 2.

Regarding the locking manner, in some embodiments, the locking is performed from the side surface of the sliding sleeve, in other embodiments, the locking is performed from the end surface of the sliding sleeve, and both of them have advantages, the former locking manner is simple and convenient, but can cause the deformation of the sliding sleeve; the latter can be adapted to small fastening components and the strength requirements for the main flange 11, for example, are relatively high.

In addition, as mentioned above, the sliding sleeve and the seat hole may adopt an interference fit, which is also called an interference connection, and after the interference fit is formed, a relatively reliable locking may be formed.

In some embodiments, the locking feature to which the locking member is adapted is configured to:

as shown in figures 1 and 2, the two sliding sleeves 1 are symmetrical with respect to the through groove middle section of the through hole axis.

Further, the base 2 is provided with fastening screw holes, such as screw holes 22 shown in fig. 1, on opposite sides thereof. Accordingly, the opposing sides are symmetrical about the through slot mid-section.

A set screw, such as the screw 3 shown in fig. 1, is provided which fits into the set screw hole for locking of the sliding sleeve halves 1.

The screws 3 are set screws, and locking of the set screws can be directly realized based on pre-tightening force of the set screws, and in a preferred embodiment, referring to fig. 1-4, it can be seen that positioning holes 13 are formed in the half sliding sleeve 1 corresponding to the set screw holes, and the set screws just extend into the positioning holes 13, so that more reliable locking can be realized.

Obviously, the positioning holes 13 are blind holes.

In some embodiments, for example, a table top or a groove can be milled on the half sliding sleeve 1, and the locking of the half sliding sleeve 1 can also be realized.

In some embodiments, a second locking manner is adopted, namely locking is performed at the end part of the half sliding sleeve 1, and the locking structure matched with the corresponding locking component comprises:

the second limiting part forms a main flange 11 as shown in fig. 6, the main flange 11 forms a flange connection with the other end of the seat hole, the longest connection mode of the flange connection in the mechanical field is a bolt or a screw connection, and the flange connection is adapted to the structure in fig. 1 and is a screw connection.

Regarding the main flange 11, a disk-shaped member may be adopted, and 2 to 6 screw holes, preferably 3 screw holes are formed on the disk-shaped member for locking the disk-shaped member with the base 2. It should be noted that 2~6 screw holes are adapted to two half sliding sleeves 1, and main flange 11 on each half sliding sleeve is adapted to 1~3 screw holes.

Further, in some embodiments, the main flange 11 can be a toothed flange as shown in fig. 6, which is suitable for the rotation of the half sliding sleeve 1 in addition to the fixed assembly.

Wherein the gullets 17 can be used for the intervention of locking screws without having to open screw holes separately.

Alternatively, when the main flange 11 is a toothed flange, the teeth are provided with locking screw holes.

As for the auxiliary flange 15, the above-mentioned description refers to its non-return for the half sliding sleeve 1, and therefore, it is used for axial limitation, and obviously, it is not necessary to be a flange or a flange-like structure, and limitation can be achieved as long as a structure such as a stopper pin is provided.

In the configuration shown in fig. 4 and 5, the secondary flange 15 constitutes a single-tooth flange whose tooth profile allows it to pass axially through said through slot 24.

Correspondingly, the secondary flange 15 is provided with a locking screw hole for locking the secondary flange 15 at one end of the seat hole.

It should be noted that, since, for example, the locking screw holes are used for locking, for example, the main flange 11, and also for locking the secondary flange 15, in some embodiments, the locking screw holes may be opened only on the main flange 11, and the locking screw holes are not opened on the secondary flange 15.

In some embodiments, the length of the seat hole is less than or equal to the length of the base between the first position-limiting portion and the second position-limiting portion of the sliding sleeve, i.e., the base is the sleeve body 12 shown in fig. 1.

When the hole length is smaller than the length of the base body, the smaller part is an assembly allowance L, the assembly allowance L is positively correlated with the size of the sliding sleeve, namely the sliding sleeve is enlarged, and the assembly allowance L is also enlarged. The presence of the assembly allowance L facilitates the assembly and adjustment of the half sliding sleeve 1.

In addition, if the sliding sleeve and the seat hole are in interference fit, the base 2 needs to be heated first during assembly, so that the volume of the base is inevitably increased, and if the assembly margin L is not provided, the length of the sleeve body 12 may be smaller than that of the seat hole, so that the assembly cannot be performed. Therefore, the remaining assembly margin L can also be applied to more assembly structures of the sliding sleeve.

Further, the fitting margin L is 1mm or more and not more than 3 mm.

In addition, as shown in FIG. 1, the sliding sleeve has rounded corners 16 at both ends of the sleeve bore.

The sliding sleeve is worn to establish and forms the rope cage shoe behind the wire rope promptly, when promoting the container and reacing the maintenance position, can release wire rope, demolishs sliding sleeve locking part, can carry out the sliding sleeve and change, and maintainability improves by a wide margin.
