Description

Technical Field

[0001] This utility model relates to the field of logistics automation technology, and in particular to a pulley block applied to rail clamping. Background Technology

[0002] In automated logistics sorting systems, high-speed, high-precision sorting trolleys are key equipment. These trolleys typically run on tracks via a rail-mounted structure. Traditional sorting trolley pulley systems have the following drawbacks: First, the supporting rollers located under the track are prone to wear after long-term high-speed operation, making replacement and maintenance extremely difficult. This requires lifting the entire trolley or disassembling numerous connecting parts, resulting in long downtime and high maintenance costs. Second, existing structures lack effective self-adjustment capabilities and cannot compensate for track installation errors or deformation after long-term operation, leading to poor contact between the rollers and the track, generating vibration, noise, and even affecting sorting accuracy. In severe cases, this can cause the trolley to jam or derail. Utility Model Content

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0020] Example 1

[0021] Reference Figures 1 to 4 As shown, this is the first embodiment of the present invention. This embodiment provides a pulley block for use with rails, including a mounting plate 1, on one side of which a crossbeam 2 is fixedly connected, and a side wheel 3 is horizontally mounted on the lower surface of the crossbeam 2.

[0022] A fixed shaft a4 is fixedly connected to one side of the mounting plate 1, and a roller a5 is rotatably connected to the fixed shaft a4;

[0023] A vertical groove 6 is provided on the mounting plate 1 and below the fixed shaft a4, and a slider 7 is slidably connected in the groove 6.

[0024] A fixed shaft b9 is detachably connected to one side of the slider 7. A roller b10 is rotatably connected to the fixed shaft b9. The fixed shaft b9 is detachably connected to the slider 7 via a quick-release assembly 8.

[0025] The connecting post 11 is fixedly connected to one side of the mounting plate 1 and located diagonally above the slide groove 6. A tension spring 12 is provided between the connecting post 11 and the slider 7. The tension spring 12 always applies an upward pulling force to the slider 7.

[0026] It should be noted that the mounting plate 1 is fixedly connected to both sides of the sorting trolley body. Each set of pulleys is preferably installed symmetrically to ensure the smooth operation of the trolley. The side wheels 3 are preferably rubber-coated wheels, which are used to abut against the track from the side to limit the trolley's lateral movement and ensure that it runs in a straight line. Roller a5 and roller b10 together clamp the main body of the track. The elastic force of the tension spring 12 needs to be precisely selected according to the weight of the trolley and the running speed to ensure that it provides sufficient and constant clamping force.

[0027] In use, the track is clamped between roller a5 and roller b10. The tension of the tension spring 12 is continuously applied to roller b10 through slider 7 and fixed shaft b9, so that it presses tightly against the bottom surface of the track. When the track is uneven or there is an installation error, slider 7 can slide up and down in the groove 6 to adaptively adjust the position of roller b10, thereby ensuring that there is always sufficient clamping force and smooth operation without impact.

[0028] In summary, the adaptive tensioning mechanism composed of slider 7, slide 6 and tension spring 12 achieves a constant clamping force of roller b10 on the track, solving the problems of poor fit, vibration and abnormal noise caused by uneven or worn track on the sorting trolley, and ensuring stability and sorting accuracy under high-speed operation.

[0029] like Figures 3 to 4 As shown, in a preferred embodiment, the slider 7 includes an insert block 701 inserted into the slide groove 6, a top plate 702 fixedly connected to one side of the insert block 701, a back plate 703 disposed on one side of the top plate 702, a positioning post 704 fixedly installed on one side of the insert block 701, a positioning groove 705 opened on one side of the back plate 703 and adapted to the positioning post 704, and a screw 706 penetrating the back plate 703 and threadedly connected to the positioning post 704.

[0030] It should be noted that the cross-section of the insert block 701 is preferably matched with the cross-section of the slide 6. The top plate 702 and the back plate 703 are clamped to both sides of the mounting plate 1 by the cooperation of the screw 706 and the positioning post 704. Assembly and maintenance are very convenient. At the sorting site, maintenance personnel do not need to disassemble the main body of the trolley. They only need to loosen the screw 706 to remove the back plate 703 and the entire slide 7 from the mounting plate 1 for maintenance or replacement.

[0031] When using the roller b10, screw 706 can be unscrewed to remove the back plate 703 and other components such as the insert block 701 from the mounting plate 1 as a whole, which facilitates subsequent operations.

[0032] In summary, the detachable structure composed of the insert block 701, top plate 702, and back plate 703 enables the rapid assembly and disassembly of the slider 7 as a whole. This solves the problem of the traditional structure of the sorting cart requiring the disassembly of multiple parts and cumbersome operation during maintenance, greatly improving maintenance efficiency and shortening system downtime.

[0033] like Figures 3 to 4 As shown, in a preferred embodiment, the quick-release assembly 8 includes a positioning seat 801 fixedly disposed on one side of the top plate 702, a connecting block 802 fixedly disposed on one side of the fixed shaft b9, through holes 803 opened on both sides of the positioning seat 801, and bolts 804 passing through the through holes 803 and threadedly connected to the connecting block 802.

[0034] It should be noted that the positioning seat 801 is provided with a groove for accommodating the connecting block 802. The connecting block 802 is provided with a threaded blind hole. The bolt 804 passes through the through hole 803 of the positioning seat 801 and is screwed into the threaded hole of the connecting block 802 to fasten the two together.

[0035] When the roller b10 under the sorting trolley wears out due to long-term high-speed operation and needs to be replaced, the maintenance personnel do not need any special tools. They can simply use a common wrench to loosen and remove the bolt 804 to remove the fixed shaft b9 together with the roller b10 from the positioning seat 801, and quickly complete the replacement without disassembling the entire slider 7 or any other parts, thus realizing online rapid maintenance.

[0036] In summary, the quick-release assembly 8, consisting of positioning seat 801, connecting block 802 and a single bolt 804, enables the rapid replacement of roller b10, perfectly solving the core pain point of the extremely difficult replacement of worn rollers on the sorting cart, significantly reducing maintenance time and labor costs, and ensuring the continuous and efficient operation of the logistics system.

[0037] like Figure 1 As shown, in a preferred embodiment, rollers a5 and b10 roll on the top and bottom of the track, respectively.

[0038] It should be noted that the rolling surfaces of rollers a5 and b10 are located in the same vertical plane to ensure that they can accurately grip the web of the track I-beam or similar structure from both the top and bottom. The roller materials can be wear-resistant nylon, polyurethane, or rubber-coated steel wheels to reduce noise and improve service life.

[0039] When in use, the track is clamped between roller a5 and roller b10. The upper part is supported by roller a5, the lower part is clamped by roller b10, and the sides are limited by side wheels 3, forming a stable three-point rail clamping structure, which effectively prevents the sorting trolley from swaying, derailing and other safety accidents when starting, stopping or turning at high speed.

[0040] In summary, the rollers a5 and b10 arranged vertically achieve reliable clamping and support of the track, solving safety problems such as swaying and derailment that may occur during the operation of the sorting trolley, and improving the safety and reliability of the system operation.

[0041] like Figures 1 to 4 As shown, in a preferred embodiment, the top plate 702 and back plate 703 of the slider 7 are located on both sides of the mounting plate 1, respectively, and constrain the outer walls of the mounting plate 1 on both sides of the slide groove 6.

[0042] It should be noted that the area of ​​the top plate 702 and the back plate 703 is larger than the width of the slide groove 6, so that they can cover the outer surface of the mounting plate 1, so that the slider 7 is completely positioned in the thickness direction of the mounting plate 1 and can only slide up and down along the slide groove 6, but cannot move back and forth, thus eliminating the movement gap.

[0043] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
