Description
Technical Field
[0001] This utility model belongs to the technical field of rope-type pneumatic cart pushers, and more specifically, it relates to the rope guide pulley assembly of a rope-type pneumatic cart pusher. Background Technology
[0002] A rope-type pneumatic trolley is a device that uses a pneumatic motor to drive a steel rope winding mechanism, and uses a closed steel rope to pull the trolley along the track. It is mainly used for pushing rail vehicles in scenarios such as mines and shaft yards.
[0003] As a core piece of equipment for pushing rail vehicles in scenarios such as mines and underground parking lots, the tension adjustment of the steel rope closed-loop system of rope-type pneumatic trolleys directly affects the stability and safety of equipment operation. Currently, most tensioning devices used in the industry are based on the principle of vertical height adjustment, that is, by adjusting the vertical position of the tensioning wheel or counterweight, the path length of the steel rope is changed to achieve tension control. For example, common screw-lift tensioning mechanisms or hydraulic cylinder-driven tensioning devices all rely on a large vertical space to complete the vertical displacement of the tensioning wheel. However, in working environments with limited vertical space (such as low mine roadways, narrow track curves, etc.), such traditional tensioning devices are limited by the vertical height of the installation area, and the tensioning wheel cannot be fully raised and lowered, resulting in a limited or even completely ineffective range of steel rope tension adjustment. The steel rope is prone to slippage, derailment, or breakage due to slack. Utility Model Content
[0004] Common screw-type lifting tensioning mechanisms or hydraulic cylinder-driven tensioning devices all require a large vertical space to complete the vertical displacement of the tensioning wheel. However, in working environments with limited vertical space (such as low mine roadways, narrow track curves, etc.), such traditional tensioning devices are limited by the vertical height of the installation area, and the tensioning wheel cannot be fully raised and lowered. This utility model proposes a rope-type pneumatic trolley pulley assembly to overcome the above-mentioned technical problems existing in related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a rope-type pneumatic trolley pusher rope guide pulley assembly, including a winding assembly. The outer surface of the winding assembly is provided with a steel rope, and the outer surface of the steel rope is provided with a guide assembly. The outer surface of the guide assembly is respectively provided with a limit assembly and a retaining assembly. The winding assembly is used to wind up and unwind the steel rope. Both ends of the steel rope are fixedly connected to the trolley pusher. The guide assembly is used to adjust the tension of the steel rope. The limit assembly is used to limit the guide assembly. The retaining assembly is used to prevent the steel rope from detaching from the guide assembly.
[0007] Furthermore, the winding assembly includes a base, a pneumatic motor is fixedly mounted on the top of the base, a flange is fixedly mounted on the output shaft of the pneumatic motor, a fixing bolt is threaded onto the outer surface of the flange, a winding roller is fixedly connected to the flange by the fixing bolt, and the steel rope is wound around the outer surface of the winding roller.
[0008] Furthermore, the guiding assembly includes a bracket, a rotating frame is rotatably connected to the outer surface of the bracket, a first guide wheel and a second guide wheel are rotatably connected to the outer surface of the rotating frame, the steel rope overlaps with the first guide wheel and the second guide wheel respectively, and the steel rope passes from above the first guide wheel to below the second guide wheel and out.
[0009] Furthermore, the limiting component includes a connecting shaft, which is fixedly connected to the rotating frame and rotatably connected to the bracket. An ear plate is fixedly connected to the outer surface of the connecting shaft, and a limiting bolt is threadedly connected to the outer surface of the ear plate. A circular plate is fixedly connected to the outer surface of the limiting bolt, and an arc groove is formed on the outer surface of the bracket. The limiting bolt is located inside the arc groove.
[0010] Furthermore, the retaining assembly includes a support rod, which is fixedly connected to the rotating frame by a fixing bolt. A first half-ring is fixedly connected to the outer surface of the support rod, and a second half-ring is fixedly connected to the top of the first half-ring by a fixing bolt. The steel cable passes between the first half-ring and the second half-ring.
[0011] Furthermore, both the first and second half-rings are rotatably connected to ball bearings.
[0012] Furthermore, a handwheel is fixedly connected to the outer surface of the coupling.
[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model connects a steel rope and a guide assembly. The steel rope passes through the guide assembly. When the limiting assembly separates from the guide assembly and the limiting and fixing of the guide assembly is released, the guide assembly can be pushed to rotate so that the steel rope is tightened. The overall size of the guide assembly is fixed and does not require additional space, making it easy to adjust in environments with limited height.
[0015] 2. By connecting the first guide wheel and the second guide wheel, the steel rope passes through the top of the first guide wheel and then out from the bottom of the second guide wheel. This allows the steel rope to be guided from a high place to a low place for movement. At this time, the height of the steel rope is similar to the height of the pusher, which can avoid the situation where the higher steel rope generates an upward oblique force when pulling the pusher and thus does useless work.
[0016] 3. This utility model connects the support rod and the first half-ring. The support rod rotates with the rotating frame, and the support rod drives the first half-ring and the second half-ring to rotate. The steel rope passes through the first half-ring and the second half-ring. The first half-ring and the second half-ring can limit the steel rope and prevent the steel rope from jumping out of the first guide wheel and the second guide wheel when the steel rope is slack.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0029] Please see Figures 1-6 As shown, this utility model is a rope guide pulley assembly for a rope-type pneumatic trolley, including a winding assembly 1. A steel rope 2 is provided on the outer surface of the winding assembly 1, and a guide assembly 3 is provided on the outer surface of the steel rope 2. A limit assembly 4 and a retaining assembly 5 are respectively provided on the outer surface of the guide assembly 3. The winding assembly 1 is used to wind up and unwind the steel rope 2. Both ends of the steel rope 2 are fixedly connected to the trolley. The guide assembly 3 is used to adjust the tension of the steel rope 2. The limit assembly 4 is used to limit the guide assembly 3. The retaining assembly 5 is used to prevent the steel rope 2 from detaching from the guide assembly 3.
[0030] After the winding assembly 1 is started, the winding assembly 1 pulls the steel rope 2. The steel rope 2 passes through the outer surface of the guide assembly 3. Under the guidance of the guide assembly 3, the steel rope 2 maintains a certain tension so that it can pull the trolley to move in a straight line. Rotate the limiting assembly 4 to release its limiting fixation on the guide assembly 3. At this time, the guide assembly 3 can be pushed to rotate to change the tension of the steel rope 2, so that the steel rope 2 is taut to maintain straight movement. During the rotation, the holding assembly 5 always presses the steel rope 2 on the guide assembly 3 to prevent the steel rope 2 from coming off the guide assembly 3.
[0031] This utility model connects the steel rope 2 and the guide component 3. The steel rope 2 passes through the guide component 3. When the limiting component 4 separates from the guide component 3 and releases the limiting fixation of the guide component 3, the guide component 3 can be pushed to rotate so that the steel rope 2 is tightened. The overall size of the guide component is fixed, so it does not need to occupy additional space and is easy to adjust in environments with limited height.
[0032] In one embodiment, the winding assembly 1 includes a base 101, a pneumatic motor 102 is fixedly mounted on the top of the base 101, a flange 103 is fixedly mounted on the output shaft of the pneumatic motor 102, a fixing bolt 104 is threadedly connected to the outer surface of the flange 103, and a winding roller 105 is fixedly connected to the flange 103 by the fixing bolt 104, and the steel rope 2 is wound around the outer surface of the winding roller 105.
[0033] After the pneumatic motor 102 is started, the output shaft of the pneumatic motor 102 drives the flange 103 to rotate. The flange 103 drives the take-up roller 105 to rotate through the fixing bolt 104. One side of the take-up roller 105 winds up the steel rope 2, and the other side releases the steel rope 2, so as to realize the circulation of the steel rope 2 to pull the pusher to move.
[0034] In one embodiment, the guide assembly 3 includes a bracket 301, a rotating frame 302 is rotatably connected to the outer surface of the bracket 301, a first guide wheel 303 and a second guide wheel 304 are rotatably connected to the outer surface of the rotating frame 302, a steel rope 2 overlaps with the first guide wheel 303 and the second guide wheel 304, and the steel rope 2 passes from above the first guide wheel 303 to below the second guide wheel 304.
[0035] During the movement, the steel rope 2 drives the first guide wheel 303 and the second guide wheel 304 to rotate. The rotation of the first guide wheel 303 and the second guide wheel 304 reduces the friction of the steel rope 2 during movement. Under the action of the first guide wheel 303 and the second guide wheel 304, the steel rope 2 moves from a high position to a low position. When it is necessary to adjust the tension of the steel rope 2, the rotating frame 302 is pushed to drive the first guide wheel 303 and the second guide wheel 304 to rotate clockwise, which can tighten the steel rope 2. When rotated counterclockwise, the steel rope 2 can be relaxed.
[0036] In one embodiment, the limiting component 4 includes a connecting shaft 401, which is fixedly connected to a rotating frame 302 and rotatably connected to a support 301. An ear plate 402 is fixedly connected to the outer surface of the connecting shaft 401, and a limiting bolt 403 is threadedly connected to the outer surface of the ear plate 402. A circular plate 404 is fixedly connected to the outer surface of the limiting bolt 403. An arc groove 405 is formed on the outer surface of the support 301, and the limiting bolt 403 is located inside the arc groove 405.
[0037] Rotate the limiting bolt 403. Through the threaded connection between the limiting bolt 403 and the ear plate 402, the limiting bolt 403 is moved away from the rotating frame 302, and the circular plate 404 on the limiting bolt 403 is moved away from the bracket 301. At this time, the limiting fixation of the rotating frame 302 can be released. Pushing the rotating frame 302 to drive the first guide wheel 303 and the second guide wheel 304 to rotate can realize the tension adjustment. After the adjustment is completed, screw the limiting bolt 403 back, so that the limiting bolt 403 abuts against the rotating frame 302, and the circular plate 404 on the limiting bolt 403 abuts against the bracket 301. At this time, the limiting fixation between the bracket 301 and the rotating frame 302 can be realized, thereby avoiding unnecessary rotation of the rotating frame 302.
[0038] In one embodiment, the retaining assembly 5 includes a support rod 501, which is fixedly connected to the rotating frame 302 by a fixing bolt 104. A first half-ring 502 is fixedly connected to the outer surface of the support rod 501, and a second half-ring 503 is fixedly connected to the top of the first half-ring 502 by a fixing bolt 104. The steel rope 2 passes between the first half-ring 502 and the second half-ring 503.
[0039] The rotating frame 302 drives the support rod 501 to rotate, and the support rod 501 drives the first half ring 502 and the second half ring 503 to rotate. The first half ring 502 and the second half ring 503 play a limiting role on the steel rope 2, which can prevent the steel rope 2 from coming off the first guide wheel 303 and the second guide wheel 304 when the steel rope 2 is slack.
[0040] In one embodiment, for the first half-ring 502, both the first half-ring 502 and the second half-ring 503 are rotatably connected to balls 6.
[0041] When the steel rope 2 moves within the first half-ring 502 and the second half-ring 503, it drives the ball bearing 6 to rotate. The rotation of the ball bearing 6 reduces the friction between the steel rope 2 and the first half-ring 502 and the second half-ring 503.
[0042] In one embodiment, a handwheel 7 is fixedly connected to the outer surface of the aforementioned coupling 401.
[0043] The outer surface of the handwheel 7 is covered with a rubber layer to increase friction. Pushing the handwheel 7 can drive the connecting shaft 401 and the rotating frame 302 to rotate.
[0044] Through the above technical solution, 1. By connecting the steel rope 2 and the guide assembly 3, the steel rope 2 passes through the guide assembly 3. When the limiting assembly 4 separates from the guide assembly 3, releasing the limiting fixation of the guide assembly 3, the guide assembly 3 can be pushed to rotate, thereby tightening the steel rope 2. The overall size of the guide assembly is fixed, requiring no additional space and facilitating adjustment in environments with limited height; 2. By connecting the first guide wheel 303 and the second guide wheel 304, the steel rope 2 passes through the top of the first guide wheel 303 and then exits from the bottom of the second guide wheel 304, allowing the steel rope 2 to be guided from a high position to a low position for movement. When the height of the steel rope 2 is close to the height of the pusher, it can avoid the situation where the higher steel rope 2 generates an upward oblique force when pulling the pusher and does useless work; 3. Through the connection of the support rod 501 and the first half ring 502, the support rod 501 rotates with the rotating frame 302, and the support rod 501 drives the first half ring 502 and the second half ring 503 to rotate. The steel rope 2 passes through the first half ring 502 and the second half ring 503. The first half ring 502 and the second half ring 503 can limit the steel rope 2, and prevent the steel rope 2 from jumping out of the first guide wheel 303 and the second guide wheel 304 when the steel rope 2 is slack.
