[0008] In one specific embodiment, the driving wheel of the A sprocket group is coaxially connected to the output end of the motor, the driven wheel of the A sprocket group is hinged to the top of the bracket via a chain, and the chain direction of the B sprocket group is opposite and symmetrical to that of the A sprocket group.

[0009] In one specific embodiment, a fixing rod is provided on one side edge of the bottom of the box frame, and an elastic rubber block is fixed to the bottom of the fixing rod. The axis of the elastic rubber block coincides with the movement trajectory axis of the top of the bracket.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 As an embodiment of this utility model, a material transport device for a production line includes a box frame 1. A fixing plate 2 is symmetrically arranged on one side of the inner top surface of the box frame 1, and a B fixing plate 3 is symmetrically arranged on the other side of the inner top surface of the box frame 1. A counterweight component 4 is slidably connected to the surface of the B fixing plate 3. A slide rail frame 5 is fixedly connected to the front of the A fixing plate 2, and a support component 6 is slidably connected to the surface of the slide rail frame 5.

[0023] The specific problem addressed in this embodiment is the limitation of material transportation due to the various transport trajectories of materials, making longitudinal lifting and horizontal movement of materials impossible. This invention achieves the horizontal lateral movement of the fork arm 64 through the coordinated design of the electro-hydraulic rod 62 and guide rail plate 63 in the support component 6. Specifically, the electro-hydraulic rod 62 drives the connecting block 65 to move the fork arm 64 on the guide rail plate 63, solving the problem of traditional equipment's inability to flexibly adjust the horizontal position of materials, improving the accuracy of lateral material positioning and transportation efficiency. The linkage structure design of sprocket group A 8 and sprocket group B 9 achieves synchronous balance between the lifting of the bracket 61 and the reverse movement of the counterweight box 42. Specifically, when the motor 7 drives sprocket group A 8 to lift the bracket 61, sprocket group B 9 synchronously pulls the counterweight box 42 to move in the opposite direction. Utilizing the balancing effect of the multiple counterweight plates 43 within the counterweight box 42, the problem of insufficient stability caused by load changes during lifting is solved, significantly improving the stability and safety of longitudinal material lifting.

[0024] The support assembly 6 includes a bracket 61 slidably connected to the top of the slide rail frame 5. An electro-hydraulic rod 62 is symmetrically arranged on the top of the bracket 61. A guide rail plate 63 is fixedly connected to the top of the electro-hydraulic rod 62. A fork arm 64 is slidably connected to the top of the guide rail plate 63. A connecting block 65 is provided at the telescopic end of the electro-hydraulic rod 62. The top of the connecting block 65 passes through the guide rail plate 63 and is fixedly connected to the bottom of the fork arm 64. In this specific embodiment, the counterweight assembly 4 includes a pulley 41 slidably connected to the surface of the B fixed plate 3. A counterweight box 42 is fixed to the surface of the pulley 41. Multiple counterweight plates 43 are arranged inside the counterweight box 42 from top to bottom. The multi-layered counterweight plates 43 inside the counterweight box 42 realize the dynamic load balance adjustment function. The horizontally stacked counterweight plates 43 and their clearance fit with the inner wall of the counterweight box 42 allow for the increase or decrease of the number of counterweight plates according to the weight of the material, solving the problem that traditional fixed counterweights cannot adapt to different loads and improving the versatility and operational adaptability of the equipment.

[0025] In this specific embodiment, a motor 7 is provided on the top of the box frame 1, and the output end of the motor 7 is connected to a sprocket A group 8. One end of the sprocket A group 8 is fixedly connected to the top of the bracket 61, and a sprocket B group 9 is connected to one side of the bottom of the bracket 61. One end of the sprocket B group 9 is fixedly connected to the bottom of the counterweight box 42.

[0026] A motor 7 is mounted on the top of the housing frame 1. The output of motor 7 is connected to the drive wheel of sprocket set A 8. Sprocket set A 8 is fixed to the top of bracket 61 via a chain. Sprocket set B 9 is connected to the bottom of bracket 61 via a chain. Sprocket set B 9 is fixed to the bottom of counterweight box 42 via a chain. When motor 7 is driven, sprocket set A 8 drives bracket 61 to rise and fall, while sprocket set B 9 pulls counterweight box 42 to move in the opposite direction, forming a dynamic balance between lifting and counterweight. Through the synchronous reverse transmission of sprocket sets A and B, the linkage control between bracket 61 and counterweight box 42 is achieved, solving the stability problem caused by load fluctuations during lifting and improving operational safety.

[0027] In this specific embodiment, the driving wheel of sprocket group A 8 is coaxially connected to the output end of motor 7, the driven wheel of sprocket group A 8 is hinged to the top of bracket 61 via a chain, and the chain direction of sprocket group B 9 is symmetrical to the chain direction of sprocket group A 8.

[0028] The driving wheel of sprocket set A 8 is coaxially connected to motor 7, and the driven wheel is hinged to the top of bracket 61 via a chain. The chain direction of sprocket set B 9 is symmetrical to that of sprocket set A 8. When motor 7 drives sprocket set A 8 to lift bracket 61, sprocket set B 9 pulls counterweight box 42 downward synchronously via a reverse chain, counteracting the lifting inertia of bracket 61. Through the symmetrical sprocket arrangement, it is ensured that the movement directions of bracket 61 and counterweight box 42 are strictly opposite, reducing load fluctuations on motor 7 and improving energy utilization efficiency.

[0029] In this specific embodiment, a fixing rod 10 is provided on one side edge of the bottom of the box frame 1, and an elastic rubber block 11 is fixed at the bottom of the fixing rod 10. The axis of the elastic rubber block 11 coincides with the movement trajectory axis of the top of the bracket 61.

[0030] A fixing rod 10 is installed at the bottom of the housing frame 1, and an elastic rubber block 11 is fixed at its bottom. The axis of the elastic rubber block 11 is aligned with the lifting path of the bracket 61. When the bracket 61 descends to the lowest point, the elastic rubber block 11 absorbs the impact force through deformation, avoiding rigid collision. The buffer design of the elastic rubber block 11 reduces the impact of the bracket 61 hitting the bottom, solves the problem of wear caused by mechanical collision of equipment parts, and extends service life.

[0031] In this specific embodiment, the multi-layer counterweight plates 43 inside the counterweight box 42 are horizontally stacked and their edges are fitted with the inner wall of the counterweight box 42 with a clearance. Both the A sprocket group 8 and the B sprocket group 9 adopt a double-row chain drive structure.

[0032] The counterweight plates 43 inside the counterweight box 42 are horizontally stacked with their edges fitted with the inner wall of the box, facilitating the addition or removal of the number of counterweight plates. The A / B sprocket assembly uses a double-row chain drive to enhance the chain's resistance to deviation. During implementation, the number of counterweight plates 43 is adjusted according to the weight of the material. The double-row chain ensures transmission stability. Through the adjustable counterweight plates 43 and the double-row chain structure, dynamic load adaptation and improved transmission reliability are achieved, solving the problems of poor equipment versatility and chain derailment, and enhancing operational adaptability.

[0033] In this specific embodiment, the motor 7 is located at the center of the top of the housing frame 1, and its output end is vertically inserted through the housing frame 1 via a drive shaft and connected to the drive wheel of the A sprocket set 8.

[0034] Motor 7 is located at the top center of the housing frame 1, and its output end is connected to the drive wheel of sprocket group A 8 via a vertical drive shaft. The central placement of motor 7 ensures a symmetrical power transmission path, reduces the risk of chain imbalance, and optimizes the symmetry of the power transmission path through the central drive design of motor 7. This solves the problem of uneven chain force caused by traditional side-mounted motors and improves the stability of equipment operation.

[0035] Working principle: After the material is placed on top of the fork arm 64, the motor 7 drives the A sprocket group 8 to move the bracket 61 up along the slide rail 5. At the same time, the B sprocket group 9 pulls the counterweight box 42 to move down in the opposite direction along the B fixed plate 3. The load inertia of the bracket 61 is balanced by the counterweight plate 43. When the electric hydraulic rod 62 extends and retracts, it pushes the fork arm 64 to slide horizontally on the guide rail plate 63 through the connecting block 65 to adjust the lateral position of the material. When the bracket 61 descends to the lowest point, the impact is buffered by the elastic rubber block 11. This achieves a composite adjustment of longitudinal lifting and horizontal movement of the material, which solves the problems of single transportation trajectory and poor lifting stability, and improves the flexibility and efficiency of material transportation.
