Description

Technical Field

[0001] The utility model relates to the technical field of vehicle maintenance, and particularly relates to a coupler support seat compression tool. Background Art

[0002] The coupler support seat is used to support the coupler, and a wear plate is arranged between the coupler support seat and the coupler. Since there is frequent contact between the coupler and the support seat, the wear plate needs to be regularly replaced and maintained.

[0003] Referring to the Chinese utility model patent with the application number 201210555922.X, a coupler support seat and a coupler buffer device are provided. The coupler support seat is used to support the coupler. The top of the coupler support seat is a coupler wear plate, and a return spring is arranged inside the coupler support seat to buffer the impact of the coupler in the vertical direction.

[0004] For the type 17 coupler, the distance between the coupler body and the coupler impact seat is 28 mm to 40 mm. Since the wear plate is frequently worn during use and needs to be regularly replaced, when the wear plate is replaced, the distance between the support seat and the coupler body is about 20 mm to 30 mm under the action of the return spring. The thickness of the wear plate is usually selected as 29 mm. Therefore, in actual replacement, the working space is narrow, which is not convenient for replacing and adjusting the wear plate, resulting in an increase in work difficulty and a decrease in work efficiency, and cannot meet the actual work requirements.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0025] Example 1

[0026] refer to Figure 1 The present embodiment provides a coupler support seat compression tool, including a support pad 1, a lifting drive 2 and a support connector 3, the lifting drive 2 is arranged on the support pad 1, and the end of the support connector 3 is connected to the support pad 1.

[0027] When in use, the support connector 3 is connected to the top of the coupler support seat 8, the support pad 1 is arranged below the coupler support seat 8, and the lifting drive 2 is located between the support pad 1 and the bottom of the coupler support seat 8. At this time, the lifting drive 2 can be used to push the support pad 1 to move downward when it is extended. In the process of the support connector 3 connected to the support pad 1 following the support pad 1 to move downward, the support connector 3 drives the top of the coupler support seat 8 to squeeze the return spring, so that the return spring is compressed downward, thereby increasing the working space above the top of the coupler support seat 8, facilitating the installation and adjustment of the wear pad, reducing the difficulty of operation, improving the operation efficiency, and meeting actual operation needs.

[0028] Further description, in order to facilitate storage and installation, it is preferred that the support pad 1 and the lifting drive 2 are detachably connected, and the support pad 1 and the end of the support connector 3 are detachably connected.

[0029] Specifically, the support pad 1 can be detachably connected to the bottom of the lifting drive 2 by a lock, or the support pad 1 can be detachably connected to the bottom of the lifting drive 2 by magnetic attraction, bonding or adsorption.

[0030] refer to Figure 2 It is preferred that a slot 7 matching the bottom of the lifting drive 2 is provided on the top of the support pad 1. The lifting drive 2 can be optionally a jack or a hydraulic cylinder, which is detachably connected to the bottom of the lifting drive 2 through the slot 7.

[0031] Preferably, the support pad 1 is coaxially arranged with the card slot 7, so that the lifting drive 2 can be coaxially arranged with the support pad 1 during use, so that the support pad 1 is evenly stressed.

[0032] Further preferably, the connection positions between the support connecting member 3 and the support backing plate 1 are arranged at intervals around the axis of the lifting drive 2, so as to ensure the stable and reliable force application of the support backing plate 1 and avoid tipping over.

[0033] Further explanation, referring to Figure 3 , the support connecting member 3 includes a hook 4 and a traction belt 5. The end of the traction belt 5 is connected to the support backing plate 1 through the hook 4. One end of the hook 4 is connected to the traction belt 5, and the other end of the hook 4 is a bent structure for connecting to the support backing plate 1.

[0034] At this time, a connection hole 6 needs to be opened on the support backing plate 1 for cooperation with the hook 4, that is, the support connecting member 3 is detachably connected to the support backing plate 1.

[0035] Specifically, when the number of the support connecting members 3 is one, the traction belt 5 can be selected as an H-shaped structure. At this time, four hooks 4 are connected to the four ends of the traction belt 5. At this time, the number of the hooks 4 is four. Four connection holes 6 are opened on the support backing plate 1, and the four connection holes 6 are opened at the four vertex positions of the support backing plate 1. When in use, the middle position of the traction belt 5 is located at the top of the coupler support seat 8, and the four ends of the traction belt 5 extend from the outside of the coupler support seat 8 to the lower part of the coupler support seat 8 and are connected to the support backing plate 1 through the hooks 4, so as to ensure the stable and reliable use of the support backing plate 1.

[0036] When the number of the support connecting members 3 is two, one hook 4 can be connected to each end of the traction belt 5 respectively. When in use, the two traction belts 5 extend downward from the opposite sides of the coupler support seat 8 respectively to be connected to the support backing plate 1 below the coupler support seat 8.

[0037] When the number of the support connecting members 3 is multiple, preferably four, at this time, one hook 4 is connected to the bottom end of the traction belt 5, and the top end of the traction belt 5 is connected to the top of the coupler support seat 8. For example, detachable connection methods such as bonding or adsorption or clamping can be selected.

[0038] Preferably, the number of the support connecting members 3 is two.

[0039] Working principle:

[0040] During actual use, by obtaining the elastic coefficient of the return spring in the coupler support seat 8 and the number of the return springs, the magnitude of the force applied to the top of the coupler support seat 8 each time can be obtained.

[0041] Taking the elastic coefficient of a single return spring as k = 71.7 N / mm and the number of the return springs as 3 as an example for explanation.

[0042] According to the requirements, the top of the coupler support seat 8 needs to be compressed by a distance x = 70 mm. Combining with the original distance of 30 mm, a working space of 100 mm can be obtained.

[0043] Therefore, according to F = kx, the force F applied to the top of the coupler support seat 8 is F = 15.057 kN, which is converted to a mass of approximately 1536 kg. To ensure the safety and stability of each component under force, a safety value of 1600 kg is used.

[0044] At this time, the traction belt 5 can choose a Dyneema sling with high strength and light weight, which can withstand a weight of 3T and the length can be selected as 1m; the lifting drive 2 chooses a hydraulic pick (jack) that can withstand a weight of 5T, and the corresponding hook 4 also chooses one that can withstand a weight of 5T, and the support pad 1 chooses alloy steel to meet the usage requirements.
