Description

Technical Field

[0001] This utility model belongs to the technical field of roller can ear, specifically relating to a roller can ear with adjustable front and rear stroke. Background Technology

[0002] Roller can ears are a type of guiding device used for vertical shaft hoisting containers (such as skips and cages). They are installed on both sides of the hoisting container and their main function is to make the hoisting container run smoothly along the canal in the shaft, reduce the swaying and tilting of the container during operation, and ensure the safety and efficiency of hoisting operations.

[0003] The working principle of roller can ears is based on the rolling friction between the rollers and the can guide. When the hoisting container moves up and down in the shaft, the rollers of the roller can ear are in close contact with the can guide, and the rollers roll on the can guide as the container moves. Due to the low coefficient of rolling friction of the rollers, the friction between the hoisting container and the can guide can be effectively reduced, making the container run more smoothly. At the same time, the buffer device of the roller can ear can absorb and buffer the impact force generated by the hoisting container during operation, ensuring the stable operation of the container. Currently, the mainstream roller can ears on the market, after being fixedly installed on the surface of the hoisting container, are limited by the complex spatial layout of the shaft and the installation precision of the can guide. Traditional fixed roller can ears lack forward and backward stroke adjustment functions. Due to unavoidable construction errors during the installation of the can guide in the shaft, the actual can guide spacing may deviate from the design value. The rigid structure of traditional roller can ears makes it impossible for them to adaptively compensate for this error, resulting in abnormal wear between the roller and the can guide. When the well shaft undergoes local deformation or settlement, the rigidly connected roller can ears may cause the lifting container to jam due to uneven force, or even cause local stress concentration in the can guide, leading to safety accidents. Utility Model Content

[0004] The purpose of this invention is to provide a roller lug with adjustable forward and backward stroke, aiming to solve the problems of existing roller lugs. In current mainstream roller lugs, after being fixedly installed on the surface of the lifting container, they are limited by the complex spatial layout of the shaft and the precision requirements of the lug installation. Traditional fixed roller lugs lack forward and backward stroke adjustment capabilities. Due to unavoidable construction errors during lug installation within the shaft, the actual lug spacing may deviate from the design value. The rigid, fixed structure of traditional roller lugs prevents them from adaptively compensating for this error, leading to abnormal wear between the rollers and the lugs. When local deformation or settlement occurs in the shaft, the rigidly connected roller lugs may cause uneven stress, leading to blockage of the lifting container or even localized stress concentration in the lugs, potentially causing safety accidents.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a roller can ear with adjustable front and rear stroke, comprising a positioning plate and a frame mounted on the surface of the positioning plate, wherein rollers are installed inside the frame and a buffer cylinder is installed on the outer side wall of the frame;

[0006] The bottom end of the positioning plate is connected to a fixing plate, the outer side of the fixing plate is connected to a mounting side plate, the bottom surface of the positioning plate is connected to a threaded block, one end of the fixing plate is connected to a lead screw, the other end of the lead screw is connected to a receiving block, the end of the lead screw near the receiving block is connected to a rotating block, the inner wall of the fixing plate is connected to a guide rail plate, and both sides of the bottom surface of the positioning plate are connected to guide plates.

[0007] As a preferred embodiment of the adjustable front and rear stroke roller can ear of this utility model, the lead screw passes through the threaded block and extends into the interior of the fixed plate, and the lead screw is threadedly connected to the threaded block.

[0008] As a preferred embodiment of the adjustable roller can ear of this utility model, the inner side of the receiving block is connected to the inner wall of the fixing plate, and the lead screw forms a rotating structure through the rotating block and the opening on one side of the receiving block.

[0009] As a preferred embodiment of the adjustable front and rear travel roller ear of this utility model, the guide plate is L-shaped in side view, and the guide plate and the guide rail plate form a sliding connection structure.

[0010] As a preferred embodiment of the adjustable roller can ear of this utility model, a mounting block is connected to one end surface of the fixing plate near the lead screw, and a locking screw is connected through the side of the mounting block.

[0011] As a preferred embodiment of the adjustable front and rear stroke roller ear of this utility model, the locking screw is threadedly connected to the mounting block, and the locking screw passes through the mounting block and abuts against the surface of the lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model installs mounting side plates on both sides of the fixed plate into the lifting container. When the forward and backward stroke needs to be adjusted, the screw is rotated, which drives the threaded block to move back and forth inside the fixed plate. At the same time, the guide plate slides back and forth along the guide rail plate, thereby driving the rollers on the surface of the positioning plate to adjust the forward and backward stroke. This improves the convenience of using the roller can ears, while ensuring the stability of the lifting container inside the shaft and avoiding safety accidents. Attached Figure Description

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a roller can ear with adjustable front and rear stroke, including a positioning plate 1 and a frame 2 installed on the surface of the positioning plate 1, a roller 3 installed inside the frame 2, and a buffer cylinder 4 installed on the outer side wall of the frame 2.

[0022] A fixing plate 5 is connected to the bottom end of the positioning plate 1. A mounting side plate 6 is connected to the outer side of the fixing plate 5. A threaded block 7 is connected to the bottom surface of the positioning plate 1. A lead screw 8 is connected through one end of the fixing plate 5. A receiving block 9 is connected to the other end of the lead screw 8. A rotating block 10 is connected to the end of the lead screw 8 near the receiving block 9. A guide rail plate 11 is connected to the inner wall of the fixing plate 5. Guide plates 12 are connected to both sides of the bottom surface of the positioning plate 1.

[0023] Preferably, the lead screw 8 passes through the threaded block 7 and extends into the interior of the fixed plate 5, and the lead screw 8 is threadedly connected to the threaded block 7.

[0024] In practical use, rotating the threaded block 7 at this time facilitates the adjustment of the front and rear stroke of the roller can ear. When lifting the container inside the shaft, the front and rear strokes can be adjusted according to process requirements to cope with shafts in different environments and improve the practicality of the roller can ear.

[0025] Preferably, the inner side of the receiving block 9 is connected to the inner wall of the fixing plate 5, and the lead screw 8 forms a rotating structure with the opening on one side of the receiving block 9 through the rotating block 10.

[0026] In practical use, the rotating block 10 at one end of the lead screw 8 is rotated along the opening on one side of the receiving block 9, thereby facilitating the stable movement of the threaded block 7.

[0027] Preferably, the guide plate 12 is L-shaped in side view, and the guide plate 12 and the guide rail plate 11 form a sliding connection structure.

[0028] In practical use, by sliding the guide plate 12 along the surface of the guide rail plate 11, it is easy to ensure that the positioning plate 1 moves in a directional manner, and at the same time, it is easy to drive the roller can ear to move stably.

[0029] Preferably, a mounting block 13 is connected to one end of the fixing plate 5 near the lead screw 8, and a locking screw 14 is connected through the side of the mounting block 13.

[0030] In practical use, the use of mounting block 13 and locking screw 14 enhances safety.

[0031] Preferably, the locking screw 14 is threadedly connected to the mounting block 13, and the locking screw 14 passes through the mounting block 13 and abuts against the surface of the lead screw 8.

[0032] In practical use, the locking screw 14 passes through the mounting block 13 and abuts against the lead screw 8, thereby facilitating the limiting and stabilizing of the lead screw 8, thus preventing the roller can ear from shifting position and ensuring the safety of using the roller can ear.

[0033] The working principle of this utility model is as follows: First, the mounting side plates 6 on both sides of the fixed plate 5 are installed in the lifting container. Then, when the forward and backward stroke adjustment is required, the lead screw 8 is rotated, which drives the threaded block 7 to move forward and backward inside the fixed plate 5. At the same time, the guide plate 12 slides forward and backward along the guide rail plate 11. Simultaneously, the rotating block 10 at one end of the lead screw 8 rotates along the opening on one side of the receiving block 9, thereby driving the roller 3 on the surface of the positioning plate 1 to adjust the forward and backward stroke, improving the convenience of using the roller can ear, and ensuring the stability of the lifting container inside the shaft to avoid safety accidents. By passing the locking screw 14 through the mounting block 13 and abutting against the lead screw 8, the stability of the lead screw 8 is ensured, preventing the phenomenon of self-rotation and improving the safety of using the roller can ear.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
