Abstract
Description
Technical Field
[0001] This application relates to the field of load guiding technology, specifically to a load traction guide and traction method. Background Technology
[0002] In the process of handling large loads in some manufacturing processes, it is often necessary to use a traction mechanism with a rigid connection (rigid connection structure) to pull the large load. However, while the large load moves forward with the traction mechanism, its left and right direction of movement is uncertain. As the movement continues, left and right floating deviations will occur. At the same time, in cases where the ground is uneven, up and down floating deviations will also occur. More importantly, sometimes even overturning deviations will occur, showing a tendency to overturn. The aforementioned left and right floating deviations, up and down floating deviations, and overturning deviations will cause the load to deviate from the intended direction and destination, thereby generating forces that are transmitted to the traction mechanism and damaging it.
[0003] Therefore, those skilled in the art urgently need to design a guiding device for auxiliary traction of large loads. Summary of the Invention

[0007] The guide trolley has a T-shaped bottom that can slide within a T-shaped groove, and a drive shaft that extends vertically outward from its top and can slide up and down autonomously; the drive shaft is used to connect the load.
[0008] The chain is in a closed loop shape, with one part placed in a T-shaped groove and the other part placed in a square groove; after the chain passes through the driving sprocket assembly and the driven sprocket assembly, the two ends of the chain are respectively connected to the front and rear ends of the guide trolley.

[0010] The locator penetrates the side wall of the vehicle front and is inserted into the strip groove; when the load movement fluctuates up and down, the slider slides adaptively up and down along the rectangular hole under the action of the locator and the strip groove.
[0011] Based on the above technical solution, the chain drive box is welded from two layers, namely the drive box body and the guide rail; the T-shaped groove is formed on the guide rail; and the square groove is formed on the drive box body.

[0013] Based on the above technical solution, a rolling part is provided on the side of the bottom of the vehicle body to facilitate sliding, and the rolling part slides along the side of the T-shaped groove.
[0014] Based on the above technical solution, the rolling parts are bearings, and the four bearings are divided into two pairs and symmetrically installed on the left and right sides of the bottom of the vehicle body through a vertical mounting axis; the outer circular surface of the bearing is in close contact with the side of the T-shaped groove.
[0015] Based on the above technical solution, the transmission box body is a rectangular tubular structure formed by folding sheet metal, and several reinforcing plates are vertically arranged inside the rectangular tubular structure, with the square groove penetrating all the reinforcing plates.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0033] like Figures 1 to 6 As shown, this application discloses an embodiment of a load traction guide, which includes a chain drive box 1, a guide trolley 2, and a chain 4. The function of the load traction guide is to lock the movement direction of large loads, adapt to the vertical floating deviation of the load, and ensure that the traction force applied to the load is always horizontally forward, eliminating lateral floating deviation and overturning motion deviation.
[0034] Specifically, the chain drive box 1 is elongated and consists of two layers. The upper layer has an upward-opening T-shaped groove, and the lower layer has a closed square groove. The T-shaped groove serves to accommodate the chain 4 and allow the guide carriage 2 to slide. The square groove also serves to accommodate the chain 4. A drive sprocket assembly 5 and a driven sprocket assembly 6 are respectively located at both ends of the chain drive box 1.
[0035] The bottom of the guide trolley 2 is T-shaped and can be slidably set in the T-shaped groove. The bottom T-shaped guide trolley 2 is tightly fitted with the T-shaped groove of the chain drive box 1 to prevent the load from floating left and right. At the same time, the bottom T-shaped structure of the guide trolley 2 is inverted inside the T-shaped groove. The two are tightly fitted to prevent the guide trolley 2 from flipping, that is, to prevent the load from flipping and deviating.
[0036] The top of the guide trolley 2 is equipped with a drive shaft 20 that extends vertically outward and can slide up and down autonomously. The drive shaft 20 is used to connect the load. When the ground is uneven, the load movement fluctuates up and down. The slider 27 can autonomously and adaptively slide up and down to always ensure that the traction force on the load is horizontal and forward.
[0037] Chain 4 is in a closed loop shape, with one part placed in a T-shaped groove and the other part placed in a square groove, ensuring a stable connection. After passing through the driving sprocket assembly 5 and the driven sprocket assembly 6, the two ends of chain 4 are connected to the front and rear ends of the guide trolley 2, respectively.
[0038] The load traction guide of this application no longer uses a single chain guide or rail guide, but integrates chain drive and T-shaped groove guide of chain drive box 1. The design is ingenious. The chain drive provides traction power, and the T-shaped groove of chain drive box 1 eliminates the movement deviation of the load.
[0039] The bottom T-shaped guide trolley 2 fits tightly into the T-shaped groove of the chain drive box 1. The width of the bottom of the T-shaped groove and the guide trolley 2 is designed with specific dimensions to ensure that the guide trolley does not get stuck when it moves in the T-shaped groove, and the gap is not too large to prevent the load from floating left and right.
[0040] Meanwhile, the bottom T-shaped structure of the guide trolley 2 is inverted and nested inside the T-shaped groove, with the two fitting tightly together to prevent the guide trolley 2 from tipping over, thus preventing the load from deviating from its rotational movement. Similarly, the height of the T-shaped groove and the bottom of the guide trolley 2 is designed to specific dimensions to ensure that the guide trolley does not jam when moving within the T-shaped groove, while also preventing excessive gaps.
[0041] Specifically, the width and height dimensions of the T-shaped groove are designed to meet certain tolerance requirements and surface roughness, ensuring that the movement does not cause jamming and that the gaps are not too large.
[0042] Furthermore, the top of the guide trolley 2 is equipped with a drive shaft 20 that can slide up and down autonomously, and the drive shaft 20 is connected to the load; when the load moves up and down, the slider 27 can slide up and down autonomously and adaptively, eliminating the parallelism error between the load movement direction and the T-shaped slide, and always ensuring that the traction force on the load is horizontally forward, adapting to the up and down floating deviation.
[0043] The load traction guide of this application locks the movement direction of large loads, adapts to vertical floating deviations, eliminates horizontal floating deviations and overturning movement deviations, and does not generate forces that could damage the load traction guide during traction movement, thus ensuring the working safety of the load traction guide and extending its service life.
[0044] Meanwhile, the load traction guide has a simple structure, reliable operation, is sturdy and durable, lightweight, and has low processing costs.
[0045] like Figure 1 and Figure 4As shown, in one embodiment, the guide trolley 2 includes a head section 26 and a positioner 23. The head section 26 has a rectangular hole that extends through the head section 26 from left to right. A slider 27 is provided at the end of the drive shaft 20, and the slider 27 is slidably disposed within the rectangular hole. One side of the slider 27 has a vertical groove. The side of the slider 27 with the groove is in close contact with the inner surface of the rectangular hole. It is worth noting that the range of load fluctuation is within a preset range, the length of the groove of the slider 27 is a set length, and the range of the slider 27's vertical sliding ensures that the positioner 23 will not disengage from the groove.
[0046] Positioner 23 penetrates the side wall of the front of the vehicle 26 and is inserted into the strip groove to form an active sliding structure. When the load movement fluctuates up and down, slider 27 slides adaptively up and down along the rectangular hole under the action of positioner 23 and strip groove, always ensuring that the traction force applied to the load is horizontal and forward, adapting to the up and down fluctuation deviation.
[0047] The front end 26 and the positioner 23 of this application are ingeniously designed. The slider 27 is set in a rectangular hole, and under the action of the positioner 23 and the strip groove, the slider 27 can only slide up and down in the rectangular hole, flexibly adapting to the up and down floating deviation during the load movement process.
[0048] In one embodiment, the chain drive box 1 is welded from two layers: a drive box body 11 and a guide rail 12. A T-shaped groove is formed in the guide rail 12, and a square groove is formed in the drive box body 11. The chain is positioned within the T-shaped groove and the square groove, resulting in a high degree of structural integration.
[0049] In one embodiment, the guide trolley 2 includes a body 21 with a T-shaped cross-section, and the body 21 is slidably disposed in the T-shaped groove of the guide rail 12. The T-shaped body 21 is tightly fastened in the T-shaped groove of the guide rail 12, eliminating left and right floating deviations and overturning movement deviations. Ears 24 are respectively provided at the front and rear ends of the body 21, and the end of the chain 4 is connected to the ear 24.
[0050] In one embodiment, a rolling element is provided on the bottom side of the vehicle body 21 to facilitate sliding. The rolling element slides along the side 122 of the T-shaped groove. The rolling element improves the sliding performance.
[0051] like Figure 4 , Figure 5 and Figure 6 As shown, the rolling parts further utilize bearings 22. The four bearings 22 are divided into two pairs and symmetrically mounted on the left and right sides of the bottom of the vehicle body 21 via vertical mounting shafts 25. The outer circular surface of the bearing 22 is in close contact with the groove side 122 of the T-shaped slide groove.
[0052] In other embodiments, the rolling element may also be a ball bearing.
[0053] Preferably, the vertical mounting shaft 25 is installed from bottom to top, while the bearing 22 protrudes 1 mm from the bottom side of the vehicle body 21.
[0054] Specifically, the cylindrical surface of the bearing outer ring contacts the groove side surface 122 of the guide rail 12, generating rolling friction during relative movement and eliminating the lateral floating deviation of the load. The upper surface of the T-shaped bottom of the body 21 contacts the groove top surface 123 of the guide rail 12, generating sliding friction during relative movement and eliminating the overturning deviation of the load. The lower surface of the T-shaped bottom of the body 21 contacts the groove bottom surface 121 of the guide rail 12, generating sliding friction during relative movement, similarly eliminating the overturning deviation of the load.
[0055] In one embodiment, the transmission box body 11 is a rectangular tubular structure formed by folding sheet metal, and several reinforcing plates are vertically arranged inside the rectangular tubular structure, with square grooves penetrating all the reinforcing plates. The transmission box body 11 is simple to process and manufacture, has low cost, and has a stable and reliable structure.
[0056] In one embodiment, the drive sprocket assembly 5 includes a centrally located input shaft 51 for connecting to an external motor. When the input shaft 51 receives a rotational torque, the guide trolley 2 drives the load to move in a predetermined direction.
[0057] This application also discloses a traction method based on the above-mentioned load traction guide, comprising the following steps:
[0058] The end of the drive shaft 20 is fixedly connected to the load; the external motor drives the chain 4 through the active sprocket assembly 5 and the driven sprocket assembly 6, thereby driving the guide trolley 2 to slide along the T-shaped slide.
[0059] The bottom T-shaped guide carriage 2 fits tightly into the T-shaped groove of the chain drive box 1, preventing lateral displacement of the load. The bottom T-shaped structure of the guide carriage 2 is inverted and nested inside the T-shaped groove, with the two fitting tightly together to prevent the guide carriage 2 from tipping over, thus preventing load displacement. The height and width of the T-shaped groove and the bottom of the guide carriage 2 are designed with specific dimensions to ensure that the guide carriage does not jam when moving within the T-shaped groove, while also preventing excessive clearance. When vertical displacement occurs, the drive shaft 20 adapts by sliding up and down to accommodate the displacement.
[0060] Regarding the traction method, in one embodiment, the guide trolley 2 includes a trolley head 26 and a locator 23. The trolley head 26 has a rectangular hole that extends through the trolley head 26 from left to right. A slider 27 is provided at the end of the drive shaft 20, and the slider 27 is slidably disposed within the rectangular hole. One side of the slider 27 has a vertical groove. The side of the slider 27 with the groove is in close contact with the inner surface of the rectangular hole.
[0061] Positioner 23 penetrates the side wall of the front of the vehicle 26 and is inserted into the strip groove to form an active sliding structure. When the load movement fluctuates up and down, slider 27 slides adaptively up and down along the rectangular hole under the action of positioner 23 and strip groove, always ensuring that the traction force applied to the load is horizontal and forward, adapting to the up and down fluctuation deviation.
[0062] Drive shaft 20 adaptively slides up and down, including:
[0063] When the load movement fluctuates up and down, the slider 27 slides adaptively up and down along the rectangular hole under the action of the positioner 23 and the strip groove.
[0064] The traction method of this application is ingeniously designed. The slider 27 is set in a rectangular hole, and under the action of the positioner 23 and the strip groove, the slider 27 can only slide up and down in the rectangular hole, flexibly adapting to the up and down floating deviation during the load movement process.
