Description

Technical Field

[0001] The utility model belongs to the technical field of mine operations, and more specifically, particularly relates to an anti-scraping and jamming protection device for a rope-free winch pressing wheel. Background Technique

[0002] A rope-free winch is a common continuously transported device on ordinary tracks towed by a steel wire rope in a coal mine roadway. The pressing wheel is one of the main accessories of the rope-free winch, which is used to support and guide the steel wire rope to reduce its friction and wear during movement. When the rope-free winch towes a transport trolley loaded with goods to move to the position of the control valve, the pressing switch on its top is usually triggered by the clamping plate at the bottom of the transport trolley to record information such as the travel mileage and frequency of the trolley.

[0003] Based on the above, during the transportation of goods by using a rope-free winch to tow a transport trolley, since the pressing wheel is close to the control valve in position and height, when the transport trolley is transporting goods, the clamping plate of the transport trolley often scrapes and jams the pressing wheel, resulting in the deviation and damage of the pressing wheel, affecting the operation of the rope-free winch. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides an anti-scraping and jamming protection device for a rope-free winch pressing wheel to solve the problem that during the transportation of goods by using a rope-free winch to tow a transport trolley, since the pressing wheel is close to the control valve in position and height, when the transport trolley is transporting goods, the clamping plate of the transport trolley often scrapes and jams the pressing wheel, resulting in the deviation and damage of the pressing wheel, affecting the operation of the rope-free winch.

[0005] The purpose and effect of the anti-scraping and jamming protection device for the rope-free winch pressing wheel of the utility model are achieved by the following specific technical means:

[0006] The anti-scraping and jamming protection device for the rope-free winch pressing wheel includes a mounting plate;

[0007] A control valve, which is fixedly connected to the upper surface of the mounting plate;

[0008] A pressing switch, which is fixedly connected to the top of the control valve;

[0009] A trigger rod, which is fixedly connected to the lower surface of an elastic plate;

[0010] A connecting column, which is arranged above the mounting plate;

[0011] A fixing rod, which is fixedly connected to the upper surface of the mounting plate;

[0012] An elastic plate, the left end of which is slidably connected to the outside of the fixing rod;

[0013] Height adjustment component, the height adjustment component is arranged on the mounting plate;

[0014] Disassembly and replacement component, the disassembly and replacement component is arranged inside and on the mounting plate.

[0015] Furthermore, the height adjustment component includes:

[0016] Drive lead screw, the drive lead screw is coaxially and fixedly connected to the connecting column, and the drive lead screw is threadedly connected to the right end of the elastic plate;

[0017] Knob, the knob is coaxially and fixedly connected to the top of the drive lead screw.

[0018] Furthermore, the height adjustment component further includes:

[0019] Auxiliary spring, the upper end of the auxiliary spring is fixedly connected to the lower surface of the elastic plate.

[0020] Furthermore, the disassembly and replacement component includes:

[0021] Threaded post, the threaded post is threadedly connected to the top of the fixed rod;

[0022] Restricting plate, the restricting plate is fixedly connected to the threaded post.

[0023] Furthermore, the disassembly and replacement component further includes:

[0024] Restricting columns, there are four restricting columns, and the four restricting columns are dispersedly and slidably connected inside the connecting column;

[0025] Connecting plates, there are two connecting plates, and the two connecting plates are respectively fixedly connected to the inner ends of the two left restricting columns and the inner ends of the two right restricting columns;

[0026] Connecting springs, there are two connecting springs, and the two connecting springs are dispersedly and fixedly connected to the inner sides of the two connecting plates.

[0027] Furthermore, the disassembly and replacement component further includes:

[0030] Restricting holes, two restricting holes are opened, and the two restricting holes are dispersedly opened inside the bearing column.

[0031] Compared with the prior art, the present utility model has the following beneficial effects:

[0032] First, there is no longer a need to install a clamping plate for triggering the pressing switch at the bottom of the transport trolley. Instead, an elastic plate higher than the rope pressing wheel is used. When the transport trolley moves to the position of the elastic plate, the elastic plate is pressed down to trigger the pressing switch, fundamentally avoiding the possibility of damage to the rope pressing wheel caused by the clamping plate at the bottom of the transport trolley.

[0033] Secondly, by rotating the knob, the elastic plate can be flexibly moved up and down. Under the complex operation and installation conditions in the mine, it is ensured that the height of the elastic plate is higher than the rope pressing wheel of the endless rope winch and the trigger rod can trigger the pressing switch after moving downward when the transport trolley passes by, enhancing the applicability when facing different transport trolleys.

[0034] Then, the elastic plate adopts a convenient detachable design. When the elastic plate undergoes irreversible deformation due to long-term use, it can be conveniently replaced separately, ensuring the use effect while effectively reducing the use cost.

[0035] In this utility model, by removing the clamping plate at the bottom of the transport trolley and using an elastic plate higher than the rope pressing wheel as the triggering mechanism, the collision risk between the clamping plate and the rope pressing wheel is fundamentally eliminated. By adjusting the height of the elastic plate with a knob, the adaptability of the system to different transport trolleys is enhanced, ensuring that the pressing switch can be accurately triggered under various working conditions. At the same time, the elastic plate adopts a detachable design, which is convenient for individual maintenance and replacement, reducing the long-term operation cost. Description of the Drawings

[0049] A trigger rod 301, and the trigger rod 301 is fixedly connected to the lower surface of the elastic plate 3;

[0050] A connecting column 402, and the connecting column 402 is arranged above the mounting plate 1;

[0051] A fixed rod 5, and the fixed rod 5 is fixedly connected to the upper surface of the mounting plate 1;

[0052] An elastic plate 3, and the left end of the elastic plate 3 is slidably connected to the outside of the fixed rod 5;

[0053] A height adjustment assembly, and the height adjustment assembly is arranged on the mounting plate 1.

[0054] Among them, the height adjustment assembly includes:

[0055] A transmission lead screw 4, and the transmission lead screw 4 is coaxially and fixedly connected to the connecting column 402, and the transmission lead screw 4 is threadedly connected to the right end of the elastic plate 3;

[0056] A knob 401, and the knob 401 is coaxially and fixedly connected to the top of the transmission lead screw 4. The function is that by rotating the knob 401, under the guidance of the fixed rod 5, the elastic plate 3 can be driven to move up and down through the threaded transmission mechanism jointly constituted by the transmission lead screw 4 and the right end of the elastic plate 3.

[0057] Among them, the height adjustment assembly further includes:

[0058] Auxiliary spring 302, the upper end of the auxiliary spring 302 is fixedly connected below the elastic plate 3. Its function is that after the transport trolley presses over the elastic plate 3, the auxiliary spring 302 can assist the elastic plate 3 to rebound.

[0059] Specific usage method and function of this embodiment:

[0060] Remove the clamping plate of the transport trolley. The height of the elastic plate 3 is higher than the rope pressing wheel of the endless rope winch, so that when the transport trolley approaches from the right and passes over the rope pressing wheel, there will be no scraping; and the elastic plate 3 is a metal plate with strong resilience. After the transport trolley presses over the elastic plate 3, the trigger rod 301 moves downward, pressing down the push switch 201 to complete information recording.

[0061] Embodiment 2: On the basis of Embodiment 1, as shown in the attached Figure 1 to the attached Figure 6 figures, it further includes a disassembly and replacement component, and the disassembly and replacement component is arranged inside and on the installation plate 1.

[0062] Among them, the disassembly and replacement component includes:

[0063] Threaded column 601, the threaded column 601 is threadedly connected to the top of the fixed rod 5;

[0064] Restricting plate 6, the restricting plate 6 is fixedly connected to the threaded column 601. Its function is that by rotating the restricting plate 6, the threaded column 601 can be driven to rotate simultaneously and removed from the top of the fixed rod 5.

[0065] Among them, the disassembly and replacement component further includes:

[0066] Restricting columns 7, four restricting columns 7 are provided, and the four restricting columns 7 are dispersedly and slidably connected inside the connecting column 402;

[0067] Connecting plates 701, two connecting plates 701 are provided, and the two connecting plates 701 are respectively fixedly connected to the inner ends of the two restricting columns 7 on the left and the inner ends of the two restricting columns 7 on the right;

[0068] Connecting springs 702 are provided in two pieces. The two connecting springs 702 are dispersedly and fixedly connected to the inner sides of the two connecting plates 701. The function is that when the two limiting columns 7 at the upper end are pinched inward, the two connecting plates 701 can synchronously drive the two limiting columns 7 at the lower end to move inward. When the two limiting columns 7 at the upper end are released, under the elastic return action of the connecting springs 702, the four limiting columns 7 return to their original positions.

[0069] Among them, the disassembly and replacement assembly further includes:

[0070] A rotating plate 8, the bottom of the rotating plate 8 is rotatably connected to the inside of the mounting plate 1;

[0072] Limiting holes 802 are provided in two. The two limiting holes 802 are dispersedly provided inside the bearing column 801. The function is that when the connecting column 402 is inserted into the bearing column 801 and the two limiting columns 7 at the lower end are inserted into the limiting holes 802, the transmission lead screw 4 and the connecting column 402 can rotate on the mounting plate 1. When the two limiting columns 7 at the lower end contract inward into the connecting column 402, moving the transmission lead screw 4 upward can pull out the connecting column 402 from the inside of the bearing column 801.

[0073] The specific usage method and function of this embodiment:

[0074] After the elastic plate 3 has been used in collision with the transport trolley for a long time, irreversible deformation may occur, resulting in the inability of the elastic plate 3 to drive the trigger rod 301 away from the pressing switch 201 after rebounding. At this time, the elastic plate 3 needs to be replaced. First, rotate the limiting plate 6, which can drive the threaded column 601 to rotate simultaneously and remove it from the top of the fixed rod 5. Then, pinch the two upper limiting columns 7 inward, which can drive the two lower limiting columns 7 at the lower end to move inward synchronously through the two connecting plates 701. When the two lower limiting columns 7 contract inward and enter the connecting column 402, move the transmission lead screw 4 upward, which can pull out components such as the connecting column 402, the transmission lead screw 4, and the elastic plate 3 from inside the bearing column 801. Then, rotate the elastic plate 3 and screw it off from the bottom of the transmission lead screw 4. When the elastic plate 3 moves to the two upper limiting columns 7 at the top, pinch the two lower limiting columns 7 inward so that the elastic plate 3 can smoothly pass through the two upper limiting columns 7 at the top. When the elastic plate 3 moves to the two lower limiting columns 7 at the bottom, pinch the two upper limiting columns 7 inward so that the elastic plate 3 can smoothly pass through the two lower limiting columns 7 at the bottom, thereby enabling the elastic plate 3 to be separated from the transmission lead screw 4 and the connecting column 402. Then, install the new elastic plate 3 on the outside of the transmission lead screw 4 in the reverse operation. Then, insert the left side of the new elastic plate 3 outside the fixed rod 5. Then, pinch the two upper limiting columns 7 inward. After inserting the connecting column 402 into the bearing column 801, release the two upper limiting columns 7. Under the rebounding action of the connecting spring 702, the four limiting columns 7 return to their original positions. Among them, the two lower limiting columns 7 are inserted into the bearing column 801 to complete the fixation of the transmission lead screw 4 and the bearing column 801, facilitating subsequent rotation of the knob 401 to adjust the height of the elastic plate 3. Finally, install the limiting plate 6 on the top of the fixed rod 5 through the threaded column 601 to complete the replacement of the new elastic plate 3.
