Description

Technical Field

[0001] This utility model relates to the technology of using a pneumatic wrench for tire repair, specifically to a pneumatic wrench support cart. Background Technology

[0002] A pneumatic wrench is a pneumatic tool widely used in automotive repair, mechanical assembly, and other fields. It features high torque and efficiency, allowing for the quick disassembly and installation of fasteners such as bolts and nuts. However, pneumatic wrenches are relatively heavy, making them inconvenient to move between different work locations. Especially in large workshops and repair areas, frequent movement of the pneumatic wrench from one work area to another is necessary to meet varying operational needs. This has led to the development of pneumatic wrench support carts to solve the problem of convenient pneumatic wrench movement.

[0003] Before the advent of pneumatic wrench support trolleys, pneumatic wrenches were typically moved manually. This method was not only labor-intensive but also prone to causing physical injury to operators, especially when moving heavy pneumatic wrenches. Furthermore, manual handling was inefficient, wasting considerable time and energy and impacting work progress. Additionally, haphazardly placing the pneumatic wrenches could easily lead to tool damage and loss, increasing company costs.

[0004] Our company currently uses a mobile boom trolley for the pneumatic hammer, with the pneumatic hammer suspended from the front of the boom by a hoisting rope. The boom height needs to be manually adjusted, which is quite laborious. When removing or installing tire bolts, two people are required: one to turn the wheels and the other to use the pneumatic hammer to remove them. The efficiency needs to be improved. Furthermore, the use of hoisting ropes makes it easy for the bolts to slip and fall, posing a safety hazard of injuring people. Summary of the Invention

[0005] This utility model addresses the problems existing in the prior art by proposing a handcart for a pneumatic wrench support. When used by personnel, the height of the support is automatically adjusted by the retraction of the spring at the rear of the vehicle body when the pneumatic wrench is lightly lifted. Rubber wheels installed at the bottom allow for back-and-forth pushing, enabling tire repair without the need for assistance.

[0006] The technical solution adopted by this utility model is: a handcart with a blower bracket, including a body, and a mounting frame consisting of a first vertical rod and a second vertical rod is fixedly installed at the rear end of the body. The first vertical rod and the second vertical rod are spaced apart and their upper ends are fixed to push rods. The blower is installed at the front end of the blower base. The front end of the blower base is located in front of the mounting frame, and the rear end is located behind the mounting frame. The rear end of the blower base is connected to the rear end of the body through an elastic element. The blower base is hinged to the first vertical rod and the second vertical rod.

[0007] Based on the above scheme, as a preferred option, a counterweight plate is fixedly installed at the rear end of the vehicle body.

[0008] Based on the above scheme, as a preferred option, the elastic element is a spring.

[0009] Based on the above scheme, as a preferred option, the upper end of the spring is hooked onto the ear ring at the rear end of the air gun mount, and the lower end is fixed to the screw rod, which passes through the through hole at the rear end of the vehicle body to connect to the nut.

[0010] Based on the above scheme, as a preferred option, there are two springs.

[0011] Based on the above scheme, as a preferred option, the front end of the air gun base is rotatably mounted with an air gun fixing ring, and the air gun is fixed on the air gun fixing ring.

[0012] Based on the above scheme, as a preferred option, the air gun fixing ring has a mounting block, and the air gun handle seat is fixed on the mounting block.

[0013] Based on the above scheme, as a preferred option, wheels are installed at the bottom of the vehicle body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When in use, personnel can easily repair tires by gently lifting the air hammer, causing the spring at the rear of the vehicle to retract and automatically adjust the height of the support. The rubber wheels installed at the bottom can also be used to push the support back and forth, eliminating the need for assistance.

[0016] Adjust the spring tension by adjusting the position of the nut on the screw.

[0017] A connecting rod is fixed to the bottom of the air wrench fixing ring, and a sleeve is welded to the front end of the air wrench base. The connecting rod passes through the sleeve and is connected to the nut. When in use, it can be rotated gently, which improves maintenance efficiency. Attached Figure Description

[0019] Figure 2 This is a perspective view of the present invention. Detailed Implementation

[0020] The present invention will be further described below through embodiments, but the scope of the present invention is not limited thereto.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] like Figure 1-2As shown, the air gun bracket trolley includes a body 1. A mounting frame consisting of a first vertical rod 2 and a second vertical rod 3 is fixedly installed at the rear end of the body. The first vertical rod and the second vertical rod are spaced apart and their upper ends are fixed to push rods 4. The air gun is installed at the front end of the air gun seat 5. The front end of the air gun seat is located in front of the mounting frame, and the rear end is located behind the mounting frame. The rear end of the air gun seat is connected to the rear end of the body through an elastic element. The air gun seat is hinged to the first vertical rod and the second vertical rod.

[0023] The air cannon base is rotatably connected to the first and second vertical rods via pins 6, etc.

[0024] The air cannon mount forms a lever structure through a pin, and its rear end is pulled to the rear end of the vehicle body through an elastic element 7. When the operator needs to adjust the height of the air cannon, only a small amount of force is required to lift the air cannon, thus improving maintenance efficiency.

[0025] The rear end of the vehicle body is fixedly equipped with a counterweight plate 8, which contains heavy objects for counterweighting.

[0026] The elastic element is a spring, and the front-end air gun is relatively heavy, so the spring is in a stretched state.

[0027] The upper end of the spring is hooked onto the hanging ring 9 at the rear end of the air cannon mount (or it can be directly fixed), and the lower end is fixed to the screw 10 (or a hanging ring connection can be used). The screw passes through the through hole at the rear end of the vehicle body and connects to the nut. The spring tension is adjusted by adjusting the position of the nut on the screw.

[0028] There are two springs to improve stability and extend service life.

[0029] Due to the constantly changing working conditions on site, the air wrench 11 cannot be fixed at a certain angle. Therefore, the following design is made to improve ease of use: An air wrench fixing ring is rotatably mounted on the front end of the air wrench base. The air wrench is fixed on the air wrench fixing ring 12. A mounting block 13 is located on the air wrench fixing ring 12, and the air wrench handle base is fixed to the mounting block. The original air wrench handle base was a fixed iron block. During manufacturing, the iron block is cut into two, the mounting block is located between the two, and then it is fixed with bolts.

[0030] A connecting rod 14 is fixed to the bottom of the air gun fixing ring, and a sleeve 15 is welded to the front end of the air gun base. The connecting rod passes through the sleeve and is connected to the nut. When in use, it can be rotated gently, which improves maintenance efficiency.

[0031] Wheels are mounted on the bottom of the vehicle body.

[0032] It should be noted that the embodiments described above are only for explaining the present invention and do not constitute any limitation on the present invention. The present invention has been described with reference to typical embodiments, but it should be understood that the words used therein are descriptive and explanatory terms, not limiting terms. Modifications can be made to the present invention within the scope of the claims, and revisions can be made to the present invention without departing from the scope and spirit of the present invention. Although the present invention described herein relates to specific methods, materials, and embodiments, it does not mean that the present invention is limited to the specific examples disclosed herein; on the contrary, the present invention can be extended to all other methods and applications with the same function.
