Description

Technical Field

[0001] This utility model relates to the field of lifting arm tooling, and in particular to a new type of high-efficiency explosion-proof lifting arm tooling. Background Technology

[0002] For the support of the retreat passage at an 8-meter high mining height, two types of support equipment were used: ZZ18000 / 25 / 50 and ZZ18000 / 27 / 55 stacked supports. Traditional stacked support requires 10 timbers to be placed on the top beam of the stacked support to protect the locking mechanism during the first support of the roof from damage. Otherwise, the locking mechanism of the first support of the roof will lose its support capacity. However, in the 6-meter retreat passage, the maximum height of the stacked supports is between 5 and 5.5 meters. The traditional method of manually placing timbers on the top beam of the stacked supports is not only wasteful of manpower, but also involves too many layers and too high a height of timbers, which involves working at height and poses a great safety hazard. It also causes damage and waste of timbers. To replace the timbers, three used tires from special vehicles were laid on the top beam of each stacked support.

[0003] Currently, when the explosion-proof lifting machine is in operation, it is necessary to place the waste special vehicle tires on the top beam of the stack. Due to certain limitations in its tooling structure, the installation and fixing are relatively inconvenient, which further affects the work efficiency of handling and placing waste special vehicle tires.

[0004] Therefore, since the operation of installing and fixing waste special wheels is inconvenient when the above-mentioned explosion-proof lifting machine is in operation, which further affects the work efficiency of handling and placing waste special wheels, a new type of high-efficiency explosion-proof lifting arm tooling for handling and placing waste special wheels underground can be designed. Utility Model Content

[0005] In order to overcome the problem that the operation of installing and fixing waste special wheels is inconvenient when the lifting device of the explosion-proof bottom lifting machine is in operation, which further affects the work efficiency of handling and placing waste special wheels.

[0006] The technical solution of this utility model is as follows: a novel high-efficiency explosion-proof lifting arm fixture, including a mounting base, a lifting arm body, and a fixture lifting ring. Buffer grooves are provided on the lower sides of both the front and rear ends of the lifting arm body. Shock absorbers are fixedly installed at both the upper and lower ends inside the buffer grooves. Supporting slide rods are fixedly installed on both the left and right sides inside the buffer grooves. Connecting sliders are provided on the surface of the supporting slide rods. A connecting ring is provided on the fixture lifting ring. An installation groove is provided on the inner side of the mounting base. A limit frame is fixedly installed on the upper side inside the installation groove. Pin connection holes are provided on both the left and right sides inside the installation groove. An installation slot is provided on the inner side of the mounting base located on the side of the installation groove. A pin connection sleeve is provided on the upper side inside the lifting arm body.

[0007] Preferably, the tooling lifting ring can provide a load-bearing lifting component for lifting scrap special vehicle tires, facilitating the connection and fixation of ropes or other tools. The connecting slider, together with the support slide rod, can transfer the instantaneous tension to the shock absorber. The shock absorber can significantly absorb the instantaneous impact force generated during lifting. The connecting plate can balance the connecting sliders on both sides as much as possible, further enabling all shock absorbers to be subjected to near-balanced forces. The protective plate can provide some shielding for the buffer groove, protecting the inner structural components. The mounting groove can be used to install the lifting arm body, and the limiting frame can limit the lifting arm body, facilitating the alignment of the pin connecting sleeve and the pin connecting hole. The pin bolts can be used for connection and fixation, ensuring the stability and convenience of the lifting arm body installation, and further improving safety.

[0008] Preferably, the shock absorbers are evenly spaced, and both the upper and lower ends of the connecting slider are fixedly connected to the shock absorbers.

[0009] Preferably, the surface of the support slide rod is slidably connected to the connecting slider, and the connecting slider is slidably connected to the buffer groove.

[0010] Preferably, the connecting ring is fixedly connected to the connecting slider, and protective plates are fixedly installed at both the upper and lower ends of the connecting slider on the outside of the buffer groove.

[0011] Preferably, a connecting plate is fixedly installed between the two connecting sliders, and the same protective plate is fixedly installed at both the upper and lower ends of the connecting plate.

[0012] Preferably, the lifting arm body is slidably connected to the mounting base, and the upper end of the lifting arm body is in contact with the limiting frame.

[0013] Preferably, the pin connection hole and the pin connection sleeve are mutually compatible, and a pin bolt is provided between the pin connection hole and the pin connection sleeve.

[0014] The beneficial effects of this utility model are:

[0015] This new type of high-efficiency explosion-proof lifting arm fixture utilizes a modification of the existing explosion-proof bottom-lifting machine's lifting device to design an explosion-proof lifting arm fixture that meets technical requirements. The fixture provides a load-bearing lifting component for lifting scrap special vehicle tires via lifting rings, facilitating the connection and fixation of ropes or other tools. When lifting scrap special vehicle tires, a connecting slider, in conjunction with a support rod, transfers the instantaneous tension to a shock absorber. The shock absorber significantly absorbs the instantaneous impact force generated during lifting, thereby reducing wear and tear on equipment and other auxiliary tools. This solution enables the safe and efficient placement of scrap special vehicle tires onto the top beam of a stack in underground locations, improving the efficiency of handling and placing scrap special vehicle tires. The improved boom lifting fixture design enhances underground support standards and production efficiency, eliminates the need for working at heights during support operations, reduces safety hazards, and lowers labor intensity. It ensures safe and efficient completion of support projects. When installing the boom body, it is first inserted into the mounting groove of the mounting base. A limiting frame is used to limit the boom body's position, facilitating alignment between the pin connecting sleeve and the pin connecting hole. The connection is then secured with pin bolts and finally installed on mechanical equipment for operation. This innovative project significantly reduces manual handling operations, improves coal mine safety, solves the problem of low manual handling efficiency, and offers a wide range of functions including breaking, shoveling, and loading, making it highly adaptable.

Buffer grooves 4 are provided on the lower sides of both the front and rear ends of the lifting arm body 2. Shock absorbers 5 are fixedly installed at both the upper and lower ends inside the buffer grooves 4.

An installation slot 12 is provided on the inner side of the mounting base 1 located on the side of the installation groove 9. A pin connection sleeve 1 is provided on the upper side inside the lifting arm body 2. 3. The tooling lifting ring 3 provides a load-bearing lifting component for lifting scrap special vehicle tires, facilitating the connection and fixation of ropes or other tools. When connecting and lifting scrap special vehicle tires, the connecting slider 7, in conjunction with the support slide rod 6, transmits the instantaneous tension to the shock absorber 5. The shock absorber 5 significantly absorbs the instantaneous impact force generated during lifting, thereby reducing the wear and tear on the equipment and other auxiliary tools caused by the impact force. The scrap special vehicle tires are then safely and efficiently placed on the top beam of the stack. When installing the lifting arm body 2, the lifting arm body 2 is first inserted into the mounting slide groove 9 of the mounting base 1. The limiting frame 10 is used to limit the lifting arm body 2, facilitating the alignment of the pin connecting sleeve 13 and the pin connecting hole 11. The connection and fixation are achieved through the pin bolt 16, and finally, the lifting arm body 2 is installed on the mechanical equipment for operation.

[0024] Please see Figures 1-3In this embodiment, the shock absorbers 5 are evenly spaced, and both ends of the connecting slider 7 are fixedly connected to the shock absorbers 5. The surface of the supporting slide rod 6 is slidably connected to the connecting slider 7, the connecting slider 7 is slidably connected to the buffer groove 4, the connecting ring 8 is fixedly connected to the connecting slider 7, and protective plates 14 are fixedly installed on both ends of the connecting slider 7 outside the buffer groove 4. A connecting plate 15 is fixedly installed between two connecting sliders 7, and the same protective plates 14 are fixedly installed on both ends of the connecting plate 15. By modifying the original explosion-proof bottom lifting device, a design that meets the requirements is created. The explosion-proof lifting arm fixture, which meets technical requirements, provides a load-bearing lifting component for lifting scrap special vehicle tires through the fixture lifting ring 3. It facilitates the connection and fixation of ropes or other tools. When lifting scrap special vehicle tires, the connecting slider 7, in conjunction with the support slide rod 6, transmits the instantaneous tension to the shock absorber 5. The shock absorber 5 greatly absorbs the instantaneous impact force generated during lifting, thereby reducing the wear and tear on the equipment and other auxiliary tools caused by the impact force. This can solve the problem of safely and efficiently placing scrap special vehicle tires on the top beam of the stack in the well, which is conducive to improving the work efficiency of handling and placing scrap special vehicle tires.

[0025] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, the lifting arm body 2 is slidably connected to the mounting base 1. The upper end of the lifting arm body 2 is in contact with the limiting frame 10. The pin connection hole 11 and the pin connection sleeve 13 are adapted to each other. A pin bolt 16 is provided between the pin connection hole 11 and the pin connection sleeve 13. When installing the lifting arm body 2, the lifting arm body 2 is first inserted into the mounting groove 9 of the mounting base 1. The limiting frame 10 is used to limit the lifting arm body 2, so that the pin connection sleeve 13 and the pin connection hole 11 are aligned with each other. The pin bolt 16 is used to connect and fix the lifting arm body 2, and finally it is installed on the mechanical equipment for operation.

[0026] During operation, the existing explosion-proof lifting device of the bottom lifting machine is modified to design an explosion-proof lifting arm fixture that meets technical requirements. The fixture provides a force-bearing lifting component for lifting scrap special vehicle tires through the lifting ring 3, which facilitates the connection and fixation of ropes or other tools. When connecting and lifting scrap special vehicle tires, the connecting slider 7 and the support slide rod 6 are used to transfer the instantaneous tension to the shock absorber 5. The shock absorber 5 greatly absorbs the instantaneous impact force generated during lifting, thereby reducing the wear and tear on the equipment and other auxiliary tools caused by the impact force. This can solve the problem of safely and efficiently placing scrap special vehicle tires on the top beam of the stack in the well. When installing the lifting arm body 2, the lifting arm body 2 is first inserted into the installation slide groove 9 of the mounting seat 1. The limiting frame 10 is used to limit the lifting arm body 2, which facilitates the alignment of the pin connecting sleeve 13 and the pin connecting hole 11. The connection and fixation are carried out by the pin bolt 16, and finally installed on the mechanical equipment for operation.

[0027] Through the above steps, the tooling lifting ring 3 provides a force-bearing lifting component for lifting waste special vehicle tires, facilitating the connection and fixation of ropes or other tools. When connecting and lifting waste special vehicle tires, the connecting slider 7, in conjunction with the support slide rod 6, transmits the instantaneous tension to the shock absorber 5. The shock absorber 5 significantly absorbs the instantaneous impact force generated during lifting, thereby reducing the wear and tear on the equipment and other auxiliary tools caused by the impact force. This allows the waste special vehicle tires to be safely and efficiently placed on the top beam of the stack, solving the problem that the operation of installing and fixing waste special vehicle tires is inconvenient when the explosion-proof lifting machine is working, further affecting the work efficiency of handling and placing waste special vehicle tires.
