[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figures 1 to 6As shown, in one embodiment of the removal device 100 for the master cylinder plunger 210, the removal device 100 includes a temporary fixing assembly 10, a moving mechanism 20, and an auxiliary transfer platform 30. The temporary fixing assembly 10 includes a fixing ring 11 adapted to the master cylinder plunger 210, and multiple fixing legs 12 surrounding the fixing ring 11. The master cylinder plunger 210 can be inserted into the fixing ring 11 and supported by the fixing legs 12. The moving mechanism 20 can carry the temporary fixing assembly 10 and drive it to move. The auxiliary transfer platform 30 includes a bottom fixing beam 31, a vertical column 32, a traveling platform 33, and a sliding track 34. The vertical columns 32 are multiple in number, evenly distributed along the length of the bottom fixed beam 31 and all vertically fixed to the bottom fixed beam 31. The walking platform 33 is fixed to the top of the vertical columns 32. The overall shape of the walking platform 33 is U-shaped, including one horizontal walking channel 331 and two vertical walking channels 332. The horizontal walking channel 331 is parallel to the bottom fixed beam 31, and the walking platform 33 is used for construction personnel to walk. There are at least two sliding rails 34, both perpendicular to the horizontal walking channel 331 and parallel to the vertical walking channels 332, so that the moving mechanism 20 can slide along the sliding rails 34 to transfer the main cylinder plunger 210.

[0023] In this embodiment, after the main cylinder plunger 210 in the forging equipment 200 is removed and exposed, a temporary fixing component 10 is fitted onto the main cylinder plunger 210 to prevent it from tipping over. Then, the main cylinder plunger 210, together with the temporary fixing component 10, is hoisted onto the moving mechanism 20. The moving mechanism 20 moves on the sliding track 34 of the auxiliary transfer platform 30 to transfer the main cylinder plunger 210, thereby facilitating the maintenance and replacement of the main cylinder plunger 210 in the forging equipment 200.

[0024] like Figure 2 As shown, the fixing ring 11 is circular, and its inner diameter is adapted to the diameter of the master cylinder plunger 210. Specifically, the fixing ring 11 includes two annular portions 111, each annular portion 111 including an arc-shaped retaining ring 1111 and connecting ears 1112 at both ends of the arc-shaped retaining ring 1111. Multiple fixing legs 12 are connected to the outer side of each arc-shaped retaining ring 1111. The two annular portions 111 are detachably connected through the connecting ears 1112. When the master cylinder plunger 210 is removed and exposed, the two arc-shaped retaining rings 1111 are used to grip the master cylinder plunger 210 from both sides and are fixedly connected through the connecting ears 1112. This ensures that the master cylinder plunger 210 remains stable in the vertical direction and does not tip over, facilitating transportation.

[0025] like Figure 3 and Figure 4As shown, the moving mechanism 20 includes two sets of moving components 21 and a support panel (not shown). Each set of moving components 21 includes a moving crossbeam 211 and a pulley assembly 212 disposed at the bottom of the moving crossbeam 211. The moving crossbeam 211 can move on the sliding track 34 by means of the pulley assembly 212. Figure 4 In the middle, the pulley assembly 212 includes a pulley bracket 2121 and a plurality of rollers 2122 disposed at the bottom of the pulley bracket 2121, and the top of the pulley bracket 2121 is fixedly connected to the moving crossbeam 211. The bearing panel is disposed between the two sets of moving assemblies 21 and is used to support the temporary fixing assembly 10 and the master cylinder plunger 210 placed on the temporary fixing assembly 10.

[0026] Furthermore, in Figure 3 In order to prevent the temporary fixing component 10 from detaching from the moving mechanism 20, the moving component 21 also includes two stop posts 22 disposed on the top of the moving beam 211 and perpendicular to the moving beam 211. The stop posts 22 are spaced apart along the length of the moving beam 211, and the distance between the two stop posts 22 is greater than the maximum diameter of the outer contour of the temporary fixing component 10, so that the temporary fixing component 10 can be stopped by the stop posts 22 during the transfer process and will not detach from the sides of the moving component 21. At the same time, in this embodiment, the bearing panel is a steel plate welded to the moving component 21, and the width of the bearing panel does not exceed the distance between the two stop posts 22.

[0027] Furthermore, to prevent the temporary fixing component 10 from slipping during transport, the moving component 21 also includes an anti-slip rubber pad (not shown) disposed on the surface of the bearing panel, thereby increasing the friction between the temporary fixing component 10 and the master cylinder plunger 210.

[0028] like Figure 5 and Figure 6 As shown, in order to increase the safety of the auxiliary transfer platform 30, the auxiliary transfer platform 30 also includes a protective net 35 set around the walking platform 33 to prevent construction workers from falling outwards while walking on the walking platform 33.

[0029] like Figure 5 and Figure 6 As shown, the auxiliary transfer platform 30 also includes a transverse connecting rod 36 disposed between the vertical columns 32, the transverse connecting rod 36 being parallel to the bottom fixed beam 31; the transverse connecting rod 36 is preferably welded to the vertical columns 32 to enhance the stability between the vertical columns 32.

[0030] like Figure 5 and Figure 6As shown, in this embodiment, the auxiliary transfer platform 30 also includes a longitudinal reinforcing rod 37 perpendicular to the vertical column 32. The longitudinal reinforcing rod 37 is parallel to the longitudinal travel channel 332. The longitudinal reinforcing rod 37 can be detachably connected to or fixedly welded to the forging equipment 200, thereby enhancing the stability of the entire auxiliary transfer platform 30.

[0031] Furthermore, the removal device 100 for the master cylinder plunger 210 also includes a track reinforcing beam 38 disposed between two adjacent sliding tracks 34, which can enhance the stability between the sliding tracks 34.

[0032] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0033] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0034] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
