[0002] Electric shovel copper sleeves usually refer to copper accessories used in electric shovels (a large electric excavation machine). Copper sleeves are cylindrical parts, usually made of copper alloys, used to reduce friction during mechanical movement and play a role in lubrication and protection. In heavy machinery and equipment such as electric shovels, copper sleeves can be used for bushings, bearings or other parts that need to reduce wear and friction. Using copper sleeves in electric shovels can improve the operating efficiency and reliability of the equipment and reduce maintenance costs. At the same time, copper sleeves are also easy to install and replace in machinery, which helps to maintain the normal operation of the machinery and extend its service life.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0030] Copper sleeve for mining electric shovel, including:

[0031] Copper sleeve body 1;

[0032] There are multiple heat dissipation mounting holes 101, all of which are opened on the circumferential surface of the copper sleeve body 1;

[0033] An annular groove 2 is provided on the inner wall of one end of the copper sleeve body 1;

[0034] The annular plate 3 is fixed to the other side end of the copper sleeve body 1, and the annular groove 2 matches the annular plate 3;

[0035] Positioning mechanism to achieve alignment of the annular grooves 2 on the two copper sleeve bodies 1 with the annular plates 3.

[0036] In a specific embodiment of the utility model, in the device, there can be multiple copper sleeve main bodies 1, and the heat dissipation mounting holes 101 are evenly arranged on the surface of the copper sleeve main body 1. During mechanical movement, friction will generate heat. The heat dissipation mounting holes 101 may help to reduce the temperature of the copper sleeve by enhancing heat dissipation, thereby protecting the components from overheating. The heat dissipation mounting holes 101 may also be used to install bolts to fix the copper sleeve in the correct position to ensure its correct cooperation with other components. The heat dissipation mounting holes 101 can be applied according to actual needs. Both sides of multiple copper sleeve main bodies 1 are also arranged in the same way, with an annular groove 2 and an annular plate 3. During transportation, two or more copper sleeve main bodies 1 can be stacked, and the annular plate 3 is embedded in the annular groove 2, so that the two adjacent copper sleeve main bodies 1 have a snap-fitting force and will not slide off. Moreover, after the multiple copper sleeve main bodies 1 are stacked, the transportation space can be reduced, and multiple copper sleeve main bodies 1 can be transported at the same time, which is more convenient. At the same time, the positioning mechanism can clamp the annular plate 3 in the annular groove 2, so that two adjacent copper sleeve main bodies 1 cannot rotate, and the multiple copper sleeve main bodies 1 will not rotate and fall during transportation.

[0037] For details, please refer to Figure 1 and Figure 2 The positioning mechanism is composed of two positioning grooves 301 and a positioning block 201. The two positioning blocks 201 are fixed on the inner wall of the annular groove 2. The two positioning grooves 301 are opened on the surface of the annular plate 3. The positioning blocks 201 match the positioning grooves 301.

[0038] In this embodiment: when the annular plate 3 is embedded in the annular groove 2, and the positioning block 201 is slidably connected in the positioning groove 301, the two adjacent copper sleeve bodies 1 are longitudinally positioned and cannot rotate. The positioning block 201 is located on the inner side of the annular groove 2 and does not affect the smooth surface of the copper sleeve body 1. The positioning block 201 also does not protrude to the inner wall of the copper sleeve body 1 and does not affect the smoothness of the inner surface of the copper sleeve body 1. The positioning groove 301 is located on the surface of the annular plate 3 and does not affect the smoothness of the surface of the copper sleeve body 1, and will not affect the rotation of the copper sleeve body 1.

[0039] For details, please refer to Figure 2 A lubrication groove 4 is provided on the circumferential inner wall of the copper sleeve body 1 , an injection hole 401 is provided on the inner surface of the lubrication groove 4 , and the injection hole 401 penetrates to the circumferential surface of the copper sleeve body 1 .

[0040] For details, please refer to Figure 2 The circumferential inner wall of the copper sleeve body 1 is provided with two radiating grooves 402 , and both radiating grooves 402 are connected to the lubricating groove 4 .

[0041] In this embodiment: when the copper sleeve body 1 is in use, lubricating oil can be injected into the lubrication groove 4 through the injection hole 401, and spread to the two diffusion grooves 402 through the lubrication groove 4, so that the lubricating oil can spread to the components inside the copper sleeve body 1 to reduce friction and wear and extend the service life of the components.

[0042] For details, please refer to Figure 2 and Figure 3 Two bead openings 502 are provided on one side end of the copper sleeve body 1 , and two universal grooves 5 are provided on the circumferential surface of the annular plate 3 , and universal beads 501 are arranged in both universal grooves 5 .

[0043] In the present embodiment: the universal bead 501 is provided, and the universal bead 501 rotates in a universal direction in the universal groove 5, so that when a component contacts the universal bead 501, it can rotate better, and it is not easy to cause damage to the annular plate 3. The bead opening 502 is used for two adjacent copper sleeve bodies 1. When they are superimposed, the universal bead 501 is embedded in the bead opening 502, which does not affect the embedding of the annular plate 3 into the annular groove 2. At the same time, since the two universal beads 501 and the two positioning grooves 301 are distributed in a "cross" shape, the two bead openings 502 and the two positioning blocks 201 are distributed in a "cross" shape, so that the positioning block 201 matches the positioning groove 301, and the universal bead 501 matches the bead opening 502, which is not easy to be confused.

[0044] Specifically, the copper sleeve is made of copper and tin, and can be divided into different types according to the tin content, such as tin bronze, aluminum bronze, etc. Since bronze has good wear resistance and corrosion resistance, the copper sleeve body 1 has good wear resistance and corrosion resistance.

[0045] The working principle and use process of the utility model are as follows: when multiple copper sleeve bodies 1 are placed, the multiple copper sleeve bodies 1 can be stacked up and down, and the annular plate 3 is embedded in the annular groove 2. When the annular plate 3 is embedded in the annular groove 2, the positioning block 201 is slidably connected in the positioning groove 301, so that two adjacent copper sleeve bodies 1 are longitudinally positioned and cannot rotate. In this way, after the multiple copper sleeve bodies 1 are stacked, they are clamped by the clamping force of the annular groove 2 and the annular plate 3, so that the multiple copper sleeve bodies 1 are not easy to tip over when they are stacked. Multiple copper sleeve bodies 1 can be stacked, which is convenient for the movement and transportation of the copper sleeve bodies 1.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
