Description

Technical Field

[0001] The utility model relates to the technical field of endless rope pressing pulley groups, in particular to an endless rope continuous traction anti-jump pressing pulley group. Background Technique

[0002] In an endless rope continuous traction system, the pressing pulley group is one of the key components to ensure the smooth operation of the mine car. The pressing pulley group can ensure that the steel wire rope maintains a stable tension and direction during transportation, thereby improving the operation efficiency and safety of the entire system. The tension spring on it is one of the important components for the pressed pulley to reset when the mine car passes.

[0003] In the frequent use of traditional pressing pulley groups, it is easy to cause fatigue of the tension spring, resulting in inaccurate reset or non-reset of the pressing pulley. Therefore, it needs to be maintained or replaced regularly. In the existing pressing pulley groups, the tension spring is usually directly buckled in the pressing pulley group, which is not only inconvenient for disassembly and installation but also unable to adjust the tension of the tension spring. Therefore, we propose an endless rope continuous traction anti-jump pressing pulley group to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages that in the existing technology, the tension spring in the existing pressing pulley group is usually directly buckled in the pressing pulley group, which is not only inconvenient for disassembly and installation but also unable to adjust the tension of the tension spring, and to propose an endless rope continuous traction anti-jump pressing pulley group.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An endless rope continuous traction anti-jump pressing pulley group includes a base. Two upper and lower through slot openings are provided on the base. Two sliding slots are provided inside each of the two slot openings. Fixed blocks are arranged in each of the two slot openings, and pressing mechanisms are arranged in each of the two slot openings.

[0007] Among them, the pressing mechanism includes a rotating block. The rotating block is rotatably connected inside the slot opening. A fixed column is fixedly arranged at the top of the rotating block, and a pressing pulley is sleeved on the outer wall of the fixed column.

[0008] Two groups of reset components are arranged in the corresponding slot openings for resetting the pressed pulley after it is knocked open when the mine car passes.

[0009] Two groups of limiting components are arranged on the corresponding fixed blocks for fixing and adjusting the positions of the reset components.

[0010] In a possible design, the reset assembly includes a moving block. Both sides of the moving block are located in corresponding sliding grooves and are slidably connected to the sliding grooves. Grooves are provided on the sides of the moving block and the rotating block that are close to each other, and limiting rods are fixedly arranged inside the grooves. A plurality of tension springs are arranged between the two limiting rods, and the number of tension springs is at least two. By arranging the plurality of tension springs, when the mine car passes through, the pressed rope wheel after being knocked open is reset under the pulling force of the tension springs.

[0011] In a possible design, the limiting assembly includes a screw rod. The screw rod threadedly penetrates through the fixed block, and one end of the screw rod is rotatably connected to one side of the moving block. By rotating the screw rod, the moving block is driven to slide in the sliding groove, changing the distance between the moving block and the rotating block, which not only facilitates the installation and disassembly of the tension springs but also can adapt to tension springs of different specifications.

[0012] In a possible design, the other end of the screw rod is provided with a hexagonal prism that matches a hexagonal wrench, which facilitates the screwing of the screw rod.

[0013] In a possible design, two fixing plates for mounting on the track are symmetrically arranged on the top of the base.

[0014] In a possible design, nuts are threadedly connected to the tops of the two fixed columns, which can not only fix the position of the pressed rope wheel but also facilitate disassembly for replacing and maintaining the pressed rope wheel.

[0015] In this application, when the mine car passes through, the weight and speed of the mine car will cause the pressed rope wheel to be impacted and move outward. At this time, the rotating block rotates together with the pressed rope wheel, and at the same time, the fixed column and the pressed rope wheel remain relatively fixed. After the mine car passes through and leaves, the pulling force of the tension spring is transmitted to the rotating block through the limiting rod, causing the rotating block that has been rotated by the impact of the mine car to reset, thereby driving the pressed rope wheel to reset to the initial position.

[0016] The user can, according to needs, rotate a hexagonal wrench that matches the hexagonal prism to screw the screw rod. The rotation of the screw rod will drive the moving block to slide in the sliding groove, thereby changing the distance between the moving block and the rotating block. This adjustment process not only facilitates the installation and disassembly of the tension springs but also can select a suitable tension spring specification according to actual needs to adapt to different working conditions.

[0017] The fixing plates arranged on the top of the base can be used to install the pressed rope wheel group on the track to ensure its stability and reliability during the working process. At the same time, the threaded design at the top of the fixed column and the nut facilitate the position fixing and disassembly and maintenance of the pressed rope wheel.

[0018] Beneficial effects:

[0019] In the present utility model, for the endless rope continuous traction anti-jump rope pressing wheel set, through the design of the limiting component, the distance between the moving block and the rotating block can be adjusted by rotating the screw rod, thus facilitating the installation and disassembly of the tension spring.

[0020] In the present utility model, for the endless rope continuous traction anti-jump rope pressing wheel set, through the adjustable moving block, it can adapt to tension springs of different specifications, improving the flexibility and applicability of the equipment.

[0021] In the present utility model, for the endless rope continuous traction anti-jump rope pressing wheel set, the structural design is reasonable, and the connection between components is tight, not only reducing the manufacturing cost but also facilitating the daily maintenance and repair for users.

[0022] In the present utility model, through the design of the limiting component, the distance between the moving block and the rotating block can be adjusted by rotating the screw rod, thus facilitating the installation and disassembly of the tension spring. Through the adjustable moving block, it can adapt to tension springs of different specifications, improving the flexibility and applicability of the equipment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Embodiment 1

[0029] Refer to Figures 1-3 , a rope pressing wheel set, which is composed of components such as a base 1, a chute 2, a rotating block 3, a fixed column 4, a rope pressing wheel 5, a moving block 6, a tension spring 7, a fixed block 8, a screw rod 9, a limiting rod 10, and a fixing plate 11.

[0030] First, two vertically penetrating slots are opened on the base 1, and these two slots are used to install and accommodate the subsequent rope pressing mechanism and reset component. On the inner walls of the slots, two parallel sliding slots 2 are respectively opened so that the subsequent moving block 6 can slide smoothly.

[0031] Next, inside each slot, a rotating block 3 is provided. The rotating block 3 is rotationally connected to the inner wall of the slot through a suitable bearing or bushing to ensure its free rotation. On the top of the rotating block 3, a fixed column 4 is fixedly installed. A threaded hole is reserved at the top of the fixed column 4 for subsequent connection with the rope pressing wheel 5. The rope pressing wheel 5 is sleeved on the fixed column 4 and fastened by a nut connected by threads. Such a design not only ensures the stability of the rope pressing wheel 5 but also facilitates subsequent disassembly and maintenance.

[0032] To achieve the automatic reset function of the rope pressing wheel 5, a reset component is designed. The reset component mainly includes a moving block 6 and a tension spring 7. Both sides of the moving block 6 are respectively placed in the corresponding sliding slots 2 and form a sliding fit with the sliding slots 2. On the side where the moving block 6 and the rotating block 3 are close to each other, grooves are opened, and a limiting rod 10 is installed in the grooves. Between the two limiting rods 10, a plurality of tension springs 7 are connected. The number of tension springs 7 is at least two to ensure sufficient reset force. When the mine car passes by, if the rope pressing wheel 5 is knocked open, the tension spring 7 will automatically reset the rope pressing wheel 5 to the initial position under its pulling force.

[0033] To adjust the position of the reset component, a limiting component is also designed. The limiting component mainly consists of a screw rod 9. The screw rod 9 penetrates through the fixed block 8 by threads, and one end of it is rotationally connected to one side of the moving block 6. By rotating the screw rod 9, the moving block 6 can be driven to slide in the sliding slot 2, thereby changing the distance between the moving block 6 and the rotating block 3. This design not only facilitates the installation and disassembly of the tension spring 7 but also can adapt to tension springs 7 of different specifications, improving the versatility and flexibility of the present invention.

[0034] This application can be used in the technical field of endless rope rope pressing wheel sets, and can also be used in other fields applicable to this application.

To facilitate the screwing of the screw rod 9, the other end of the screw rod 9 of the present invention is designed as a hexagonal prism shape matching a hexagonal wrench, so that the operator can easily use tools for rotation operations.

[0037] Finally, at the top of the base 1, two fixing plates 11 are symmetrically arranged, and mounting holes are reserved on these fixing plates 11 for fixedly installing the entire rope pressing wheel set on the track.
