Description

Technical Field

[0001] This utility model relates to the field of main gear shifter assembly devices, and in particular to a main gear shifter assembly device. Background Technology

[0002] In the field of tractor parts manufacturing and transportation, the main gear shift lever, as a core transmission component, directly affects the assembly quality and production progress of the entire vehicle due to its transportation safety and efficiency. Currently, main gear shift lever transportation fixtures generally suffer from the following technical shortcomings: First, traditional transportation tooling often adopts a single-plane placement design, lacking three-dimensional space utilization and a scientific positioning structure. This makes the main gear shift lever susceptible to surface scratches, deformation, and other damage due to mutual collisions during transportation, increasing rework costs. Second, the fixing methods of the transportation fixtures are crude and cannot achieve precise positioning and reliable fixation for the special shape of the main gear shift lever. During bumpy transportation or frequent handling, it is prone to displacement or even tipping over, seriously threatening the safety of the parts. Furthermore, the process of retrieving and placing the main gear shift lever within the transportation fixture is cumbersome, lacking a reasonable layered layout and operational guidance. This results in operators spending considerable time and effort when counting and retrieving parts, significantly impacting production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a main gear shifter assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a main gear shifter assembly, including a base plate, a frame structure on the base plate, a support frame inside the frame structure, a mounting structure between several support frames, and a traction structure at both ends of the base plate.

[0005] As a preferred embodiment of this utility model, the frame structure includes support rods, which are located at the four corners of the base plate. A connecting plate is provided between the support rods on one side, and a connecting rod is provided between the support rods at both ends of the base plate.

[0006] As a preferred embodiment of this utility model, the support frame includes a first connecting rod, several second connecting rods are provided between a pair of first connecting rods, and a third connecting rod is provided between the second connecting rods. One side of the first connecting rod is hinged to the connecting plate, and the lower ends of the two ends of the first connecting rod on the other side are provided with positioning rods.

[0007] As a preferred embodiment of this utility model, the mounting structure includes a slot plate, a positioning plate, and an upper pad. The slot plate has several slots, the positioning plate has a pair of positioning slots, the bottom plate has a pair of slot plates, and each of the several layers of the support frame except the top layer also has a pair of slot plates. Positioning plates are provided between the slot plates on the same layer of the bottom plate or support frame. A pair of upper pads are provided below each support frame, and the upper pads are in the same vertical position as the slot plates.

[0008] As a preferred embodiment of the present invention, the traction structure includes a traction frame, which is disposed at one end of the base plate, and a traction seat is provided on the other end of the base plate.

[0009] As a preferred embodiment of this utility model, anti-collision components are provided at all four corners of the base plate, and several heavy-duty shock-absorbing casters are provided under the base plate.

[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0011] 1. Through the combined design of frame structure and multi-layer support frame, and with the staggered layout of slot plate and positioning plate, the main gear lever is placed in a three-dimensional layered manner. Compared with the traditional flat placement, the space utilization rate is greatly improved, more parts can be transferred at one time, the number of transfers is effectively reduced, it is convenient for counting, and the production efficiency is improved.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] This utility model provides a technical solution: a main gear shift lever assembly, such as... Figure 1 As shown, it includes a base plate 1, a frame structure 2 on the base plate 1, a support frame 3 inside the frame structure 2, a mounting structure 4 between several support frames 3, and a traction structure 5 at both ends of the base plate 1.

[0022] like Figure 2 , Figure 3 As shown, the frame structure 2 includes support rods 201, which are located at the four corners of the base plate 1. A connecting plate 202 is provided between the support rods 201 on one side, and a connecting rod 203 is provided between the support rods 201 at both ends of the base plate 1.

[0023] like Figure 2 , Figure 3 As shown, the support frame 3 includes a connecting rod 301, several connecting rods 302 are welded between a pair of connecting rods 301, and connecting rods 303 are welded between the connecting rods 302. One side of the connecting rod 301 is hinged to the connecting plate 202 by a spring hinge, and the lower ends of the other side of the connecting rod 301 are welded with positioning rods 304.

[0024] like Figure 5 As shown, the mounting structure 4 includes a slot plate 401, a positioning plate 402, and an upper pad 403. The slot plate 401 has several slots 404, the positioning plate 402 has a pair of positioning slots 405, the base plate 1 has a pair of slot plates 401, and the several layers of support frames 3 except the top also have a pair of slot plates 401. The slot plates 401 on the same layer of base plate 1 or support frame 3 are all provided with positioning plates 402. The support frame 3 is provided with a pair of upper pads 403 below it. The upper pads 403 are in the same vertical position as the slot plates 401.

[0025] like Figure 5 As shown, the traction structure 5 includes a traction frame 501, which is located at one end of the base plate 1, and a traction seat 502 is provided on the other end of the base plate 1.

[0026] like Figure 1 As shown, anti-collision parts 6 are provided at the four corners of the base plate 1, and several heavy-duty shock-absorbing casters 7 are provided under the base plate 1.

[0027] In practice, several support frames 3 are flipped upwards around the hinge point from top to bottom, fully exposing the bottom slot plate 401 and positioning plate 402. A main gear lever is picked up, and one end is precisely inserted into the slot 404 of the slot plate 401 on one side of the bottom plate 1, while the other end is embedded in the positioning groove 405 of the positioning plate 402. Then, another main gear lever is placed alternately on the other side of the slot plate 401 and positioning plate 402 on the same layer, utilizing the paired positioning grooves 405 to achieve an alternating arrangement and fully utilize the space. The above steps are repeated until the bottom layer is filled with main gear levers.

[0028] After the bottom layer is placed, lower the first layer support frame 3 on top of the bottom layer, allowing the upper pad 403 on it to gently press down on the bottom main gear lever. The soft PVC material of the upper pad not only secures the main gear lever but also prevents surface scratches. At this time, the positioning rod 304 below the first layer support frame 3 cooperates with the base plate 1 to ensure structural stability. Next, in the same manner, lower the second and subsequent layers of support frames 3 one by one. After each layer is lowered, place the main gear lever alternately between the slot plate 401 and the positioning plate 402 of that layer until all the main gear levers are in place.

[0029] When the main gear shift assembly needs to be transferred, if transported alone, it can be connected to a tractor or other traction equipment via a towing frame 501. After the tractor starts, it will drive the assembly to move smoothly. If several assemblies need to be transported at once, the towing frame 501 of one assembly can be connected to the tractor, and the remaining assemblies can be connected end to end via towing seats 502 to form a turnover queue. With the help of heavy-duty shock-absorbing casters 7, the entire turnover queue can turn flexibly and move smoothly. During the movement, the anti-collision parts 6 provide full protection, reducing collision damage between assemblies and with the outside world. The heavy-duty shock-absorbing casters 7 effectively buffer bumps and protect the main gear shift from damage.

[0030] When the main gear lever needs to be removed, first flip the topmost support frame 3 upwards to expose the next-uppermost main gear lever. Starting from the top layer, lift each main gear lever from the positioning slot 405 in reverse order of placement, and then pull out the slot 404. After removing one layer of main gear levers, flip the corresponding support frame 3 and continue removing the next layer until all main gear levers have been removed. This method of removing gear levers layer by layer from the top allows for clear verification of the number of paired main gear levers, facilitating inventory management.

[0031] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
