[0015] The present invention provides a pulley installation structure for a high-position stacker, which has the following beneficial effects: 1. In the pulley installation structure of the high-position stacker, when the pull rope drives the pulley group assembly to rotate, it will continuously and uniformly squeeze with multiple stabilizing plates, thereby prompting the stabilizing plates to approach the inner surface of the moving ring through the elastic force of the plug-in strip and the elastic plate. Since the outer surface of the stabilizing plate is connected with the squeezing plate, and the squeezing plate is supported by a rubber material, the pull rope will continuously generate squeezing force with the squeezing plate, forcing the squeezing plate to be recessed toward one side of the stabilizing plate. At the same time, the elastic force brought by the elastic plate causes an elastic squeezing force to exist between the squeezing plate and the pull rope, and the strong friction force between the pull rope and the rubber material increases the friction resistance between the pull rope and the moving ring, thereby greatly improving the friction resistance between the pulley group assembly and the pull rope, thereby greatly reducing the possibility of relative sliding between the pull rope and the pulley group assembly, and avoiding the problem that the pulley of the current stacker often slides relative to the pull rope when moving, resulting in unstable movement.

At the same time, when the pull rope contacts the extrusion plate, it contacts from one end of the extrusion plate until it moves to the other end, and then the pull rope will start to squeeze the extrusion bag when it just contacts the extrusion plate. As the moving ring moves, the air pressure at the other end of the extrusion bag continues to increase, thereby expanding outward, so that the extrusion plate always maintains a convex state, which not only greatly improves the service life of the extrusion plate, but also ensures that the pull rope always maintains a strong extrusion state with the extrusion plate when it is extruded and moved on the moving plate, further reducing the possibility of relative sliding between the pull rope and the pulley assembly, thereby greatly improving the working stability of the present structure.

[0017] 3.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a high-position stacker pulley mounting structure, comprising a mounting tube 1, the outer surfaces of both ends of the mounting tube 1 are fixedly connected to the stacker, and further comprising: The pulley assembly 2 is rotatably connected to the outer surface of the middle part of the mounting tube 1, wherein the pulley assembly 2 is in extrusion contact with the slide rail, and the pulley assembly 2 drives the stacker to move along the slide rail through the mounting tube 1, and is driven to rotate by a motor; A limiting mechanism 3, which is movably mounted inside the mounting tube 1, and which limits the movement trajectory of the pulley assembly 2 on the mounting tube 1; The pulley assembly 2 includes a plug-in ring 21, three of which are arranged on the outer surface of the mounting tube 1, and the three plug-in rings 21 are rotatably sleeved on the outer surface of the mounting tube 1 at a fixed interval, a connecting plate 22 is fixedly connected to the outer surface of the plug-in ring 21, and a roller 23 is rotatably connected to the inner surface of the plug-in ring 21, wherein a plurality of rollers 23 are arranged at fixed intervals around the central axis of the plug-in ring 21, and six connecting plates 22 are arranged in a group at fixed intervals around the central axis of the plug-in ring 21, a fixing hole 24 is penetrated through the connecting plate 22, a connecting rod 25 is fixedly inserted in the fixing hole 24 by bolts, and a movable ring 26 is fixedly connected to the end of the connecting plate 22 away from the plug-in ring 21, and the cross-section of the movable ring 26 is set to be U-shaped.

[0022] The outer surface of the moving ring 26 is provided with disconnection grooves 27 , wherein six disconnection grooves 27 are provided at fixed intervals along the central axis of the moving ring 26 . The inner surface of the moving ring 26 is provided with elastic grooves 28 , wherein the elastic grooves 28 are arranged in an arc shape.

[0023] An elastic plate 29 is fixedly connected in the elastic groove 28, and the cross-section of the elastic plate 29 is set to be S-shaped. The end of the elastic plate 29 away from the elastic groove 28 is fixedly connected to a plug-in strip 210, which is set to be arc-shaped, wherein the end of the plug-in strip 210 away from the elastic plate 29 initially protrudes from the inner surface of the moving ring 26.

[0024] A stabilizing sheet 211 is fixedly connected to the outer surface of the plug-in strip 210 . The cross section of the stabilizing sheet 211 is set to be U-shaped. The stabilizing sheet 211 is set to be arc-shaped as a whole, and there is a gap between the stabilizing sheet 211 and the moving ring 26 initially.

[0025] The middle outer surface of the stabilizing plate 211 is symmetrically fixedly connected with an extrusion plate 212 . The cross-section of the extrusion plate 212 is arc-shaped. The extrusion plate 212 is made of rubber material. The outer ends of the extrusion plate 212 penetrate the stabilizing plate 211 and are fixedly connected to the inner surfaces of both sides of the moving ring 26 .

[0026] The inner surface of the extrusion plate 212 is fixedly connected with a reinforcing sheet 213, which is set as an elastic metal sheet. The inner surface of the reinforcing sheet 213 is fixedly connected with an extrusion bag 214, which is set in a strip shape. The outer surface of the extrusion bag 214 away from the reinforcing sheet 213 is fixedly connected to the outer surfaces of both sides of the stabilizing sheet 211.

[0027] During operation, if the structure needs to be installed, the structure can be fixedly installed on the top of the stacker, and then the three moving rings 26 are placed on the slide rail so that the bottom inner surface of the moving ring 26 contacts the slide rail, and then the pull rope driven by the motor is fitted to the top inner surface of the moving ring 26 to complete the installation of the structure. When the travel motor at the bottom of the stacker works, the pulley assembly 2 will be driven by the pull rope to start rotating along the installation tube 1, so that the pulley assembly 2 moves on the slide rail and drives the stacker to move. When the pull rope drives the pulley assembly 2 to rotate, it will continuously and uniformly squeeze the multiple stabilizing plates 211, thereby promoting The stabilizing sheet 211 is moved closer to the inner surface of the moving ring 26 by the elastic force of the plug strip 210 and the elastic plate 29. Since the outer surface of the stabilizing sheet 211 is connected to the extrusion plate 212, and the extrusion plate 212 is supported by a rubber material, the pull rope will continuously generate an extrusion force with the extrusion plate 212, forcing the extrusion plate 212 to be recessed toward the side of the stabilizing sheet 211. At the same time, the elastic force brought by the elastic plate 29 causes an elastic extrusion force to exist between the extrusion plate 212 and the pull rope. The strong friction between the pull rope and the rubber material increases the friction resistance between the pull rope and the moving ring 26, thereby greatly reducing the friction resistance between the pulley assembly 2 and the pull rope. The earth is greatly improved, thereby greatly reducing the possibility of relative sliding between the pull rope and the pulley assembly 2, avoiding the problem of relative sliding between the pulley of the current stacker and the pull rope during movement, resulting in unstable movement. At the same time, since the inner surface of the extrusion plate 212 is fixedly connected with the reinforcement sheet 213, and the inner surface of the reinforcement sheet 213 is fixedly connected with the extrusion bag 214, the reinforcement sheet 213 can be used to ensure that the extrusion plate 212 is always concave inward when being squeezed by the pull rope, thereby avoiding the extrusion plate 212 from folding after being squeezed by the pull rope, reducing the structural safety of the extrusion plate 212, thereby greatly improving the durability of the extrusion plate 212, and at the same time, the pull rope and the extrusion plate When the pull rope contacts the extrusion plate 212, it starts to contact from one end of the extrusion plate 212 until it moves to the other end. Then, when the pull rope just contacts the extrusion plate 212, it will begin to squeeze the extrusion bag 214. As the moving ring 26 moves, the air pressure at the other end of the extrusion bag 214 continues to increase, thereby expanding outward, so that the extrusion plate 212 always remains in a convex state, which not only greatly improves the service life of the extrusion plate 212, but also ensures that the pull rope always maintains a strong extrusion state with the extrusion plate 212 when it is extruded and moved on the moving plate, further reducing the possibility of relative sliding between the pull rope and the pulley assembly 2, thereby greatly improving the working stability of the present structure.

[0028] Second embodiment: Figures 1 to 8 As shown, the limiting mechanism 3 includes a plug-in rod 31, one end of which is slidably plugged into the inner surface of the mounting tube 1, and the other end of the plug-in rod 31 is fixedly connected to a plug-in seat 32, the plug-in seat 32 and the mounting tube 1 are plugged into each other, and the outer surface of the plug-in rod 31 is slidably connected to a ring 33.

[0029] The interior of the collar 33 is configured to be hollow, and a fixing plate 34 is fixedly connected to the outer surface of the collar 33. One end of the fixing plate 34 away from the collar 33 is fixedly connected to the inner surface of the mounting tube 1, wherein three fixing plates 34 are arranged at fixed intervals around the central axis of the collar 33, and a telescopic rod 35 is also passed through and fixedly connected to the outer surface of the collar 33. Three telescopic rods 35 are arranged at fixed intervals around the central axis of the collar 33, and a plug-in block 36 is fixedly connected to the outer end of the telescopic rod 35.

[0030] An insert groove 37 is formed through the outer surface of the mounting tube 1, and the insert block 36 is slidably inserted in the insert groove 37. A clamping groove 38 is formed on the inner surface of the insert ring 21, and the clamping groove 38 is arranged in a ring shape. The outer end of the insert block 36 is arranged in the clamping groove 38 through the insert groove 37. An extrusion ring 39 is fixedly connected to the outer surface of the insert rod 31. A bellows 310 is fixedly connected to the end surface of the extrusion ring 39 close to the sleeve ring 33. The end of the bellows 310 away from the extrusion ring 39 is fixedly connected to the outer surface of the sleeve ring 33, wherein the internal cavity of the bellows 310 is connected to the internal cavity of the sleeve ring 33.

[0031] During operation, by setting the moving ring 26, the connection strength between the pulley block assembly 2 and the slide rail can be greatly improved, and the possibility of the pulley block assembly 2 being derailed can be greatly reduced. At the same time, when the pulley block assembly 2 is installed, it can be inserted into the outer surface of the installation tube 1 through the plug ring 21, and then the plug seat 32 is pushed into the inside of the installation tube 1, that is, the plug rod 31 is driven to move into the installation tube 1 through the plug seat 32, thereby driving the extrusion ring 39 to move toward the side of the ring 33, thereby squeezing the bellows 310 between the squeezing ring 39 and the ring 33, so that the internal air pressure of the bellows 310 is increased. The sleeve 33 is raised and its internal air pressure is transmitted to the telescopic rod 35, and the sleeve 33 is passed into the telescopic rod 35, so that the telescopic rod 35 expands outward, thereby pushing the plug-in block 36 to move to the outside of the plug-in slot 37 and finally enters the card slot 38, thereby completing the limiting of the plug-in ring 21, so that the pulley block assembly 2 and the mounting tube 1 form a whole, thereby greatly improving the working stability of the present structure, and the pulley block assembly 2 can be disconnected from the mounting tube 1 by pulling the plug-in seat 32 outward, so that the pulley block assembly 2 is easy to remove for maintenance, which greatly improves the operational flexibility of the present structure.
