Description

Technical Field

[0001] The utility model relates to the technical field of alloy steel swing arms, in particular to an alloy steel swing arm used on a miniature loader. Background Art

[0002] The alloy steel swing arm on a mini loader generally refers to a mechanical component made of alloy steel that is used to support and operate the loader's stick or other tool attachments. This swing arm is usually precisely designed and manufactured to ensure that it can provide reliable performance and durability under various working conditions.

[0003] 1. Existing alloy steel swing arms are usually integrated, and the arm body and the connecting sleeve cannot be disassembled and separated. Therefore, when the arm body is damaged, the user needs to replace the connecting sleeve together with the arm body. The connecting sleeve is also equipped with several other parts, which is very inconvenient to disassemble. Replacing the arm body and the connecting sleeve together also increases the user's maintenance cost.

[0004] 2. Existing alloy steel swing arms are usually of fixed length. When the working space is limited, it is inconvenient for the loader to enter and exit the narrow space. Usually, the staff is required to move the load into the moving range of the loader's swing arm, which increases the tediousness of the work and reduces its work efficiency. Utility Model Content

[0005] The utility model aims to provide an alloy steel swing arm for a mini loader, so as to solve the problems of the existing alloy steel swing arm in the use process proposed in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An alloy steel swing arm for a mini loader comprises an arm body and a connection sleeve, wherein a spring is fixedly arranged inside the arm body, and a button is installed on the top of the spring;

[0008] A sleeve hole is provided on the surface of the connecting sleeve, and the button fits into the sleeve hole;

[0009] A connecting steel column is welded on the inner side of the arm body, wherein an electric cylinder is installed on one side of the connecting steel column, and a telescopic rod is movably installed on the top of the electric cylinder.

[0010] Preferably, the connecting holes are evenly arranged on one side of the arm body;

[0011] A slide groove is provided inside the first section of the arm body;

[0012] The sliding column is movably installed inside the arm body, and a blocking column is arranged on the top of the sliding column.

[0013] Preferably, a second connecting steel column is welded to the top of the telescopic rod, and the arm bodies are arranged on both sides of the second connecting steel column.

[0014] Preferably, a fixed column is installed in the center of the connecting sleeve.

[0015] The embodiment of the utility model provides an alloy steel swing arm for a mini loader, which has the following beneficial effects:

[0016] 1. By setting a button, a sleeve hole and a spring, a person inserts the arm body into the interior of the connecting sleeve by pressing the button, and then the button rebounds to the interior of the sleeve hole by the rebound force of the spring, so that the arm body and the connecting sleeve can be movably connected. When one of the arm bodies or the connecting sleeves on both sides of the alloy steel swing arm is damaged and needs to be replaced, there is no need to discard the entire swing arm for replacement. The arm body can be pulled out of the connecting sleeve by pressing the button, so that the person only needs to replace the damaged part, thereby reducing its maintenance cost.

[0017] 2. By setting up electric cylinders and telescopic rods, since the arm body is divided into two parts, the electric cylinder fixedly installed inside the arm body through the connecting steel column 1 makes the telescopic rod on the top of the electric cylinder push against the connecting steel column 2 and move forward according to the instructions of the personnel's electric remote control, thereby making the other side of the arm body fixedly welded on both sides of the connecting steel column 2 move forward, so that the loader can adapt to different working scenes and depth requirements, improve flexibility and versatility, and improve its work efficiency.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example: Figure 1 , Figure 2 as well as Figure 3 As shown, an alloy steel swing arm for a mini loader, when one of the arm body 1 or the connecting sleeve 2 on both sides of the alloy steel swing arm is damaged and needs to be replaced, two personnel respectively press the buttons 3 on both sides of the arm body 1 to pull the arm body 1 out of the connecting sleeve 2, wherein the button 3 is pushed down by the spring 7, and the arm body 1 is no longer fixed to the connecting sleeve 2, and the button 3 is matched with the sleeve hole 6 opened on the surface of the connecting sleeve 2, so that the arm body 1 and the connecting sleeve 2 can be movably disassembled, and there is no need to discard the entire swing arm for replacement; at the same time, the connecting holes 5 evenly opened at both ends of the arm body 1 can be movably connected to a variety of clamping devices.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, to extend the length of the arm body 1, the electric cylinder 9 installed at one end of the connecting steel column 1 8 welded between the two arm bodies 1 is operated, and the personnel control the electric cylinder 9 through remote control, so that the telescopic rod 10 connected to the top of the electric cylinder 9 pushes the connecting steel column 2 11, wherein the two sides of the connecting steel column 2 11 are respectively welded with the arm body 1, wherein the arm body 1 is divided into left and right parts, and a slide groove 14 is opened inside the right arm body 1, so that the slide column 12 installed on the top of the left arm body 1 can penetrate into the slide groove 14, wherein the blocking column 13 installed on the top of the slide column 12 can limit the extension range of the right arm body 1, so that the other side arm body 1 fixedly welded on both sides of the connecting steel column 2 11 is pushed forward, so that the loader can adapt to different working scenes and depth requirements, improve flexibility and versatility, and improve its work efficiency; in order to improve the stability of its alloy steel swing arm, a fixed column 4 is passed through the center of the connecting sleeve 2.

[0028] Working principle: First, two personnel press the buttons 3 on both sides of the arm body 1 respectively to pull the arm body 1 out of the connecting sleeve 2, wherein the button 3 is pushed down by the spring 7, and the arm body 1 is no longer fixed and restricted by the connecting sleeve 2, and the electric cylinder 9 installed at one end of the connecting steel column 1 8 welded between the two arm bodies 1 is operated, and the personnel control the electric cylinder 9 through remote control, so that the telescopic rod 10 connected to the top of the electric cylinder 9 pushes the connecting steel column 2 11, so that the sliding column 12 installed on the top of the left arm body 1 can penetrate into the slide groove 14, wherein the blocking column 13 installed on the top of the sliding column 12 can limit the extension range of the right arm body 1, thereby making the other side arm body 1 fixedly welded on both sides of the connecting steel column 2 11 move forward.

[0029] In this embodiment: the remote control circuit of the electric cylinder 9 can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field.
