Description

Technical Field

[0001] The utility model belongs to the technical field of buffer installation auxiliary devices, and in particular relates to a device for quickly replacing a large buffer. Background Art

[0002] In existing large vehicles and overhead cranes, the buffer is an important component connecting the vehicle and the frame, which plays a role in shock absorption and stability. The buffer is provided with a base, and the base is provided with a mounting hole. During installation, the base of the buffer needs to be installed on the corresponding mounting seat. Except for the difference in thickness, the other dimensions of the mounting seat are basically the same as those of the buffer base, and there are also mounting holes. After aligning the mounting holes on the buffer base and the mounting seat, the bolts are inserted and tightened to complete the installation. Under the influence of long-term use and road conditions, the buffer will be worn and damaged and needs to be replaced in time. The traditional replacement method requires the removal of multiple screws and parts, which is cumbersome and time-consuming. In addition, the buffers of large vehicles and overhead cranes are large. The alignment of the mounting holes requires 1-2 people to lift and align, and it is necessary to continue to lift for a period of time for others to bolt. Sometimes, in order to shorten the time for bolting, it is necessary to increase the number of personnel to speed up the bolting. Otherwise, the lifting personnel may not be able to hold on and cause the buffer to fall, causing a safety accident. The work intensity is high, which brings inconvenience to the maintenance work and low installation efficiency. Therefore, a device for quickly replacing large buffers is needed to solve this problem. Summary of the invention

[0003] The utility model aims to provide a device for quickly replacing a large buffer to solve the problems existing in the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Furthermore, the front baffle is provided with a first notch, a second notch, and a third notch, the rear baffle is provided with a second notch and a third notch, and the distance between the front baffle and the rear baffle is greater than the sum of the thicknesses of the base and the mounting seat of the buffer.

[0008] Furthermore, the first notch on the front baffle is located at one end of the front baffle close to the fixing member, the third notch on the front baffle is located at the other end of the front baffle, the second notch is located between the first notch and the third notch, the width of the first notch is greater than the width of the buffer base, and the distance between the second notch and the third notch is the distance between the mounting holes of the buffer base.

[0009] Furthermore, the positions and sizes of the second notch and the third notch on the rear baffle correspond to the positions of the second notch and the third notch on the front baffle.

[0010] Furthermore, the fixing piece is in a U-shape, the upper clamping plate is bolted to the inner wall at the top end of the fixing piece, and the lower clamping plate is cross-armed on the inner wall at the bottom end of the fixing piece.

[0023] like Figure 1-3 As shown, a device for quickly replacing a large buffer comprises an upper card plate 1 and a lower card plate 2. One end of the upper card plate 1 and the lower card plate 2 is bolted with a fixing part 3, a lifting rod 4 is welded to the bottom end of the fixing part 3, the other ends of the upper card plate 1 and the lower card plate 2 are welded through a connecting plate 5, a front baffle 6 and a rear baffle 7 are provided on the upper card plate 1 and the lower card plate 2, and an upper handle 8 is welded to the upper top surface of one end of the upper card plate 1 bolted with the fixing part 3.

[0024] The upper card plate 1 is located above the lower card plate 2. The upper card plate 1, the front baffle plate 6, and the rear baffle plate 7 form a U-shaped structure in cross section. The opening of the U-shaped structure of the upper card plate 1 faces downward. The lower card plate 2, the front baffle plate 6, and the rear baffle plate 7 form a U-shaped structure in cross section. The opening of the U-shaped structure of the lower card plate 2 faces upward. The base 16 and the mounting seat 15 are clamped by two upper and lower opposite U-shaped structures, and the base 16 and the mounting seat 15 can slide therein, so as to replace the buffer.

[0025] The front baffle 6 is provided with a first notch 9, a second notch 10, and a third notch 11, and the rear baffle 7 is provided with a second notch 10 and a third notch 11, and the distance between the front baffle 6 and the rear baffle 7 is greater than the sum of the thicknesses of the buffer base 16 and the mounting seat 15. The first notch 9 is used to allow the buffer base 16 to enter between the upper card plate 1 and the lower card plate 2, and then the buffer is horizontally slid to align the base 16 with the mounting seat 15.

[0026] The first notch 9 on the front baffle 6 is located at one end of the front baffle 6 close to the fixing member 3, the third notch 11 on the front baffle 6 is located at the other end of the front baffle 6, the second notch 10 is located between the first notch 9 and the third notch 11, the width of the first notch 9 is greater than the width of the buffer base 16, and the distance between the second notch 10 and the third notch 11 is the distance between the mounting holes 17 of the buffer base 16. The second notch 10 and the third notch 11 are used to make way for the mounting holes 17, so as to facilitate the use of a wrench to tighten the screws, and then install the buffer on the mounting seat 15.

[0027] The positions and sizes of the second notch 10 and the third notch 11 on the rear baffle 7 correspond to those of the second notch 10 and the third notch 11 on the front baffle 6. The second notch 10 and the third notch 11 on the rear baffle 7 are also for the convenience of using a wrench to tighten the screws, thereby installing the buffer on the mounting seat 15.

[0028] The fixing member 3 is in a square shape, the upper cardboard 1 is bolted to the inner wall at the top of the fixing member 3, and the lower cardboard 2 is cross-armed on the inner wall at the bottom of the fixing member 3. The fixing member 3 is used to fix the upper cardboard 1 and can support the lower cardboard 2.

[0029] The lifting rod 4 is plugged with a sleeve 12, a support plate 13 is welded to the bottom of the sleeve 12, a plurality of bolts 14 are threadedly connected to one side of the top of the sleeve 12, and the bolt tails of the bolts 14 are threadedly connected and penetrate the sleeve 12 and then abut the lifting rod 4. Since the installation height of the buffer of different equipment is different, it is necessary to adjust the height of the lifting rod 4 according to the actual situation, so as to support the utility model under different installation environments.

[0030] The working principle of the utility model is:

[0031] When in use, first disassemble the bolted position of the fixing piece 3 and the upper clamping plate 1. At this time, one end between the upper clamping plate 1 and the lower clamping plate 2 is open. Insert the mounting seat 15 between the upper clamping plate 1 and the lower clamping plate 2 from the open end, and then push the connecting plate 5 or pull the upper handle 8 to move the utility model horizontally until the second notch 10 and the third notch 11 are respectively facing the mounting hole 17 on the mounting seat 15.

[0032] The fixing member 3 is sleeved on the upper clamping plate 1 and the lower clamping plate 2, and the upper clamping plate 1 is bolted to the fixing member 3. By loosening the bolt 14, the extension height of the lifting rod 4 is adjusted so that the lifting rod 4 can support the utility model on the ground.

[0033] Lift the buffer so that its base 16 extends from the first notch 9 between the upper card plate 1 and the lower card plate 2, and move the buffer toward the mounting seat 15 so that the mounting holes 17 of the mounting seat 15 and the base 16 are aligned. At this time, the buffer can be released. Since the front baffle 6 and the rear baffle 7 clamp the base 16, the buffer will not fall off. Bolt the base 16 of the buffer to the mounting seat 15.

[0034] The bolted connection between the fixing member 3 and the upper clamping plate 1 is disassembled, and the connecting plate 5 is pulled to separate the utility model from the base 16 and the mounting seat 15, thereby completing the replacement of the buffer.

[0035] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.
