Description

Technical Field

[0001] This utility model belongs to the technical field of mine hoists, specifically relating to a small simulated mine hoist for friction lining tests. Background Technology

[0002] Mine hoists are indispensable key equipment in mining production, mainly used for lifting or lowering ore, materials, equipment, and personnel. Multi-rope friction hoists are a common type of hoist, achieving their lifting function through the friction between friction pads on the drum and the wire rope. The design of the rope grooves on the friction pad surface has a significant impact on the hoist's operating efficiency and safety; wear or deformation of the rope grooves can lead to wire rope slippage, increased vibration, and even safety accidents.

[0003] In practical applications, the performance of friction pads needs to be verified and optimized through extensive testing. However, due to the large size and complex structure of mine hoists, conducting tests directly on actual equipment is not only costly but also poses safety hazards. To address these issues, the industry typically uses simplified testing facilities to test the performance of friction pads. However, existing testing devices often have limited functionality and cannot fully simulate the actual working conditions of hoists, especially in terms of insufficient accuracy in simulating drum speed, load changes, and friction conditions. Furthermore, when the wear on the rope grooves of the friction pads becomes excessive, the friction pads need to be disassembled and repaired, resulting in a large workload and low efficiency. Utility Model Content

[0004] This invention provides a small-scale simulated mine hoist for friction lining testing, which solves the problems mentioned in the background art of existing simulation equipment for friction lining having limited functionality and being unable to quickly repair the lining.

[0005] The technical solution adopted in this utility model is: a small simulated mine hoist for friction lining testing, comprising:

[0006] frame;

[0007] Rotatable hoist drum;

[0008] Friction pads are installed on the outer wall of the drum. Multiple friction pads are connected end to end and surround the circumference of the drum. Each friction pad has at least two rope grooves on its outer surface.

[0009] The repair mechanism includes a repair cutter that can move freely and rotate in the horizontal direction. The horizontal centerline of the repair cutter is coplanar with the horizontal center axis of the drum. The repair cutter can contact the friction pad to repair the rope groove.

[0010] The repair mechanism also includes:

[0011] The first linear module is mounted on the frame and near the hoist drum;

[0012] The second linear module is installed on the moving platform on top of the first linear module. When the first linear module is working, it can drive the second linear module to move in the horizontal direction.

[0013] The repair motor is mounted on a moving platform on top of the second linear module. When the second linear module is working, it can drive the repair motor to move horizontally.

[0014] The repair tool is connected to the output shaft of the repair motor.

[0015] The friction pads are provided in at least two rows on the outer wall of the hoist drum, and each row of friction pads is provided with a corresponding steel wire rope.

[0016] The frame is provided with a rotatable first sheave and a second sheave at the end away from the hoist drum. A wire rope extending from above the hoist drum passes around the first sheave and extends downwards, with its end connected to the first counterweight. A wire rope extending from below the hoist drum passes around the second sheave and extends downwards, with its end connected to the second counterweight.

[0017] The first sheave, the second sheave, and the center of the hoist drum are all synchronously connected to a drive shaft, and both ends of the drive shaft are connected to bearing seats mounted on the frame.

[0018] The first and second wheels are respectively mounted on the drive shaft, and the first and second wheels can move axially on the drive shaft. The first and second wheels are fixedly connected to the drive shaft by locking screws.

[0019] The drive shaft end of the hoist drum is connected to a hoisting motor, which is mounted on one side of the frame and is configured to drive the hoist drum to rotate.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model has a reasonable design structure. By designing a mini mine hoist with a structure similar to that of actual equipment, the use of friction lining is simulated. This not only reduces costs and safety hazards, but also effectively controls data such as the speed and load of the hoist drum, improving test accuracy. In addition, a repair tool is set on one side of the hoist drum, which can quickly repair the rope groove of the friction lining without disassembling the friction lining. It has the advantages of convenient operation and high work efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] As shown in the figure, a small simulated mine hoist for friction lining testing includes:

[0030] Frame 1 is assembled from aluminum alloy profiles, featuring a robust structure, flexible assembly, and aesthetically pleasing appearance.

[0031] The rotatable hoist drum 2, specifically, has a hoisting motor 7 connected to the end of the drive shaft 12 of the hoist drum 2. The hoisting motor 7 is mounted on one side of the frame 1 and is configured to drive the hoist drum 2 to rotate. In this example, the hoisting motor 7 can be a servo motor, which can automatically control its speed according to actual needs to meet the different speed requirements of the hoist drum 2 during the test phase.

[0032] Friction pads 8 are installed on the outer wall of the drum. Multiple friction pads 8 are connected end-to-end and surround the circumference of the drum. Each friction pad 8 has at least two rope grooves 801 on its outer surface. In this example, as... Figure 4As shown, there are two rope grooves 801 on a single friction pad 8. This is because in the actual test simulation, only a single steel wire rope 9 is needed on a single friction pad 8. The steel wire rope 9 is attached to one of the rope grooves 801 to achieve the lifting effect. When one of the rope grooves 801 is damaged, the steel wire rope 9 can be placed in the other rope groove 801, and the damaged rope groove 801 can be repaired using the repair tool 6 without affecting the test process.

[0033] The repair mechanism includes a repair cutter 6 that can move freely and rotate in the horizontal direction. The horizontal center line of the repair cutter 6 is coplanar with the horizontal center axis of the drum. The repair cutter 6 can contact the friction pad 8 to repair the rope groove 801.

[0034] The repair mechanism also includes:

[0035] The first linear module 3 is installed on the frame 1 and near the hoist drum 2;

[0036] The second linear module 4 is installed on the moving platform on top of the first linear module 3. When the first linear module 3 is working, it can drive the second linear module 4 to move in the horizontal direction.

[0037] Repair motor 5 is installed on the moving platform on top of the second linear module 4. When the second linear module 4 is working, it can drive repair motor 5 to move in the horizontal direction.

[0038] Among them, the repair tool 6 is connected to the output shaft of the repair motor 5;

[0039] In this example, the main purpose of the repair mechanism is to provide the repair tool 6 with a working state that allows it to move freely in the horizontal direction, so that the repair tool 6 can move to different parts of the rope groove 801 for repair. During the repair process, the repair motor 5 drives the repair tool 6 to rotate, while the hoist drum 2 rotates under the action of the hoist motor 7, so that the rope groove 801 part of the friction pad 8 can be quickly cut and repaired.

[0040] The friction pads 8 are provided in at least two rows on the outer wall of the hoist drum 2. Each row of friction pads 8 is provided with a corresponding wire rope 9. In this example, the two rows of friction pads 8 are respectively provided at the positions near both ends of the hoist drum 2, so that the hoist drum 2 can be subjected to uniform force when the wire rope 9 pulls the counterweight up and down.

[0041] The frame 1, at the end furthest from the hoist drum 2, is equipped with a rotatable first sheave 10 and a second sheave 11. A wire rope 9 extending from above the hoist drum 2 passes over the first sheave 10 and extends downward, with its end connected to a first counterweight 14. A wire rope 9 extending from below the hoist drum 2 passes over the second sheave 11 and extends downward, with its end connected to a second counterweight 15. This is mainly used to simulate the working state of the actual hoist. The weights of the first counterweight 14 and the second counterweight 15 can be changed according to actual needs to meet the simulation test requirements under different load conditions. More specifically, the circumferential surfaces of the first sheave 10 and the second sheave 11 are both provided with annular grooves to accommodate the wire rope 9 and prevent it from falling off.

[0042] The first sheave 10, the second sheave 11, and the center of the hoist drum 2 are all synchronously connected to a drive shaft 12, and both ends of the drive shaft 12 are connected to bearing seats 13 mounted on the frame 1.

[0043] The first wheel 10 and the second wheel 11 are respectively mounted on the drive shaft 12, and the first wheel 10 and the second wheel 11 can move axially on the drive shaft 12. The first wheel 10 and the second wheel 11 are fixedly connected to the drive shaft 12 by locking screws. This arrangement is mainly to flexibly adjust the position of the first wheel 10 and the second wheel 11 to correspond to the position of different rope grooves 801 and improve the test effect.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
