Description

Technical Field

[0001] The utility model relates to the technical field of lining blocks for guide wheels, in particular to a protective device for lining blocks for guide wheels. Background Art

[0002] The function of the mine hoist sheave lining and guide sheave lining is to separate the wire rope from the metal sheave body, preventing the wire rope from direct contact with the metal sheave body, thereby protecting the wire rope and sheave from wear.

[0003] During the lifting and lowering operation of the elevator shaft, the guide wheel drives the wire rope to lift and lower the elevator. Therefore, when installing the elevator guide wheel and wire rope, special attention should be paid to the fact that the wire rope does not come into direct contact with the guide wheel to avoid wear. The guide wheel lining blocks currently available on the market are often just a small block made of polyurethane material. They need to be replaced regularly after a period of use to avoid damage to the guide wheel lining blocks due to large friction during long-term use, which leads to faster wear efficiency of the guide wheel. Moreover, this type of guide wheel lining block is not reinforced during installation. What's worse, the lining block will fall off when the guide wheel is in operation, making the elevator shaft unsafe.

[0004] Therefore, we provide a guide wheel pad protection device. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A protective device for a guide wheel pad, such as Figures 1-4As shown, it includes a block 1 and a contact block 2 arranged above the block 1, a groove 3 is provided on the surface of the contact block 2, and a plurality of buffer rods 16 are installed under the contact block 2. Top plates 6 are installed on both sides of the block 1, and two bevel gears 13 are installed inside the block 1. The surfaces of the bevel gears 13 are meshed and connected with driven gears 14. When installing the guide wheel lining block, the lower surface of the block 1 is placed on the inner diameter of the guide wheel, and the wire rope is connected through the groove 3 provided above the contact block 2. When the guide wheel is in operation, the wire rope is in direct contact with the contact block 2, and the pressure and friction force on the contact block 2 are relieved to a certain extent by the buffer rod 16 installed under the contact block 2, thereby avoiding the pressure on the guide wheel. The strong force is directly transmitted to the block 1 installed with the guide wheel, which can effectively reduce the pressure on the block 1, thereby ensuring the connection between the block 1 and the guide wheel and extending the service life of the lining. When installing the lining, the handle 4 above the block 1 is rotated to drive the umbrella gear 13 inside the block 1 to rotate, thereby causing the driven gear 14 meshing with it to rotate, and the screw rod 15 fixedly installed with the driven gear 14 drives the telescopic rod 9 to be pushed outward inside the second sleeve 8, thereby allowing the top plate 6 installed at one end to be fixedly clamped with the inner surface of the guide wheel, and then the block 1 can be firmly installed on the inner diameter surface of the guide wheel, so as to increase the service life of the guide wheel lining and strengthen the installation effect.

[0026] like Figures 1-4 As shown, a plurality of mounting grooves 11 are provided on the upper surface of the block 1, and a buffer rod 16 is installed inside the mounting groove 11. The upper end of the buffer rod 16 is fixedly installed with the contact block 2. Through the provided mounting grooves 11, the buffer rod 16 can be fixedly installed inside thereof, thereby providing an installation carrier.

[0027] like Figures 1-4 As shown, two plug holes 10 are provided on the upper surface of the block 1, and a first sleeve 5 is installed inside the plug hole 10, and a first rotating rod 12 is installed inside the first sleeve 5. A handle 4 is installed on the upper end of the first rotating rod 12, and the umbrella gear 13 is located below the first sleeve 5. The first sleeve 5 is fixedly installed inside the plug hole 10, and the first rotating rod 12 is rotatably installed inside the first sleeve 5. The handle 4 is fixedly installed on the upper end of the first rotating rod 12, and the first rotating rod 12 passes through the first sleeve 5 and is fixedly installed with the umbrella gear 13. By rotating the handle 4, the first rotating rod 12 is driven to rotate inside the first sleeve 5, and then the umbrella gear 13 fixed to one end of the first rotating rod 12 drives the driven gear 14 to rotate, thereby achieving the effect of transmitting rotational force.

[0028] Example 2: A protective device for a guide wheel pad, such as Figures 1-4As shown, a second sleeve 8 is installed on both sides of the block 1, a screw rod 15 is installed inside the second sleeve 8, a driven gear 14 passes through the second sleeve 8 and is fixedly installed with the screw rod 15, a top plate 6 is installed on one side of the second sleeve 8, and the screw rod 15 is rotatably installed inside the second sleeve 8. Driven by the driven gear 14, the screw rod 15 drives the telescopic rod 9 to extend outward, thereby enabling the top plate 6 to be reinforced and installed with the guide wheel.

[0029] like Figures 1-4 As shown, the second sleeve 8 is fixedly mounted on both sides of the block 1, the screw rod 15 is rotatably mounted inside the second sleeve 8, the end of the screw rod 15 away from the driven gear 14 is installed with a telescopic rod 9, the end of the telescopic rod 9 away from the screw rod 15 is rotatably mounted with a mounting block 7, one side of the mounting block 7 is fixedly mounted on the surface of the top plate 6, and one end of the telescopic rod 9 will only rotate inside the mounting block 7, so that the top plate 6 only extends forward following the telescopic rod 9 instead of rotating with the telescopic rod 9, thereby achieving the effect of fixing the position.

[0030] Working principle: When installing the guide wheel lining block, place the lower surface of the block 1 at the inner diameter of the guide wheel, and connect the wire rope through the groove 3 opened above the contact block 2. When the guide wheel is in operation, the wire rope is in direct contact with the contact block 2, and the pressure and friction force exerted on the contact block 2 will be alleviated to a certain extent by the buffer rod 16 installed under the contact block 2, thereby preventing the pressure exerted on the guide wheel from being directly transmitted to the block 1 installed with the guide wheel. This can effectively reduce the pressure on the block 1, thereby ensuring the connection between the block 1 and the guide wheel and extending the service life of the lining block. When installing the lining block, the handle 4 above the block 1 is rotated to drive the umbrella-shaped gear 13 inside the block 1 to rotate, thereby causing the driven gear 14 meshing with it to rotate, and the screw rod 15 fixedly installed with the driven gear 14 drives the telescopic rod 9 to be pushed outward from the inside of the second sleeve 8, thereby causing the top plate 6 installed at one end of it to engage with the guide wheel The inner surface of the wheel is fixedly clamped, and the block 1 can be firmly installed on the inner diameter surface of the guide wheel, so as to increase the service life of the guide wheel pad and strengthen the installation. Through the provided installation groove 11, the buffer rod 16 can be fixedly installed inside it, which plays the effect of providing an installation carrier. By rotating the handle 4, the first rotating rod 12 is driven to rotate inside the first sleeve 5, and the umbrella-shaped gear 13 fixedly installed on one end of the first rotating rod 12 drives the driven gear 14 to rotate, which plays the effect of transmitting the rotational force. Driven by the driven gear 14, the screw rod 15 drives the telescopic rod 9 to extend outward, so that the top plate 6 can be reinforced and installed with the guide wheel. One side of the mounting block 7 is fixedly installed on the surface of the top plate 6, and one end of the telescopic rod 9 will only rotate inside the mounting block 7, so that the top plate 6 only extends forward following the telescopic rod 9 without rotating with the telescopic rod 9, thereby fixing the position.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
