[0037] Working principle of the present invention: the anti-collision effect of the self-lubricating slider body 1 can be improved by the anti-collision plate 2, thereby reducing the impact generated when the self-lubricating slider body 1 collides. When in use, the heavy-load bearing component 7 on the top of the self-lubricating slider body 1 can improve the load-bearing effect. Since the bearing guard plate 71 is installed on the top of the self-lubricating slider body 1, the top end surface of the self-lubricating slider body 1 can be protected by the bearing guard plate 71. The load structure is installed and positioned through the positioning column 711 and the positioning plate 79 on the top of the shock-absorbing block 710, and fasteners are used to pass through the positioning holes on the surface of the positioning column 711 to connect and fix, and fasteners are used to pass through the locking holes on the surface of the positioning plate 79 and the locking holes on the surface of the locking plate 78 to connect and fix, so that the bottom end surface of the load structure is fitted and installed on the top of the load chassis 77. During the movement of the self-lubricating slider body 1, the shock-absorbing block 710 and the load chassis 77 can have a good buffering effect. Inside the buffer column 72, the buffer pressure rod 74 is squeezed, so that the guide rod 75 slides in the guide groove 73. , and elastically buffered by the bearing spring 76, effectively reducing the impact on the self-lubricating slider body 1, avoiding affecting the normal sliding of the self-lubricating slider body 1, and reducing the wear on the contact surface through the lubricating component 3 at the bottom of the self-lubricating slider body 1. Since the end face of the wear-resistant bottom pad 31 contacts the contact surface, when the self-lubricating slider body 1 slides, the fiber-based solid lubricating material filler 34 inside the filling groove 33 and the lubricating material can contact the contact surface through the covering film 35, thereby reducing the wear on the wear-resistant bottom pad 31 and the contact surface. In addition, During the sliding process between the wear-resistant bottom pad 31 and the contact surface, the gas and heat on the contact surface are easily dissipated through the guide groove 32, thereby avoiding shaking caused by excessive local pressure. At the same time, the heat generated by the wear-resistant bottom pad 31 will be transferred to the heat dissipation fins 4, and the self-lubricating slider body 1 will generate heat when sliding, so that the self-lubricating slider body 1 transfers the heat to the heat dissipation fins 4 through the heat conduction plate 6, so that the heat dissipation fins 4 can easily increase the heat dissipation rate through the heat dissipation holes 5, reduce the temperature of the self-lubricating slider body 1, and also reduce the evaporation loss of the lubricating oil.

[0038] A method for modifying an oil-free self-lubricating slider for a base of an aerial work forklift comprises the following steps:

[0039] Step S1: installing an anti-collision plate 2 on the self-lubricating slider body 1, and fixing the anti-collision plate 2 on the center of the two side end surfaces of the self-lubricating slider body 1;

[0040] Step S2: installing a lubrication assembly 3 on the bottom end surface of the self-lubricating slider body 1, opening a guide groove 32 on the end surface of the wear-resistant bottom pad 31, and opening a filling groove 33 between the guide grooves 32, and filling the fiber-based solid lubricating material filler 34 inside the filling groove 33, and using a covering film 35 to seal the top of the fiber-based solid lubricating material filler 34, and then fitting the wear-resistant bottom pad 31 on the bottom end surface of the self-lubricating slider body 1, fixing the heat dissipation fin 4 on the outside of the wear-resistant bottom pad 31, and filling the heat conduction plate 6 between the heat dissipation fin 4 and the self-lubricating slider body 1;

[0041] Among them, the fiber-based solid lubricating material filler 34 is a metal fiber-based solid self-lubricating material, and its processing technology is as follows:

[0042] a. Powder metallurgy process is used, with gold fiber as the matrix and MoS 2 It is a lubricating source for solid self-lubricating materials, thereby preparing metal fiber-based solid self-lubricating materials;

[0043] b. Since the fiber has high strength, high elastic modulus and good permeability, after sintering, the fiber matrix formed has point connections and line connections, so that the fibers bite each other to form a strong porous skeleton and a honeycomb structure;

[0044] Since metal fibers have many through holes, they are conducive to the impregnation, storage and effective transportation of lubricants, so that metal fiber-based solid self-lubricating materials can have better tensile strength and impact toughness, as well as better self-lubricating properties, effectively reducing friction and wear;

[0045] The covering film 35 is a high-density fiber mesh, and the high-density fiber mesh is adhered to the surface of the fiber-based solid lubricant filler 34 by extrusion;

[0046] The high-density fiber mesh can achieve good oil delivery effect, thereby improving the lubrication quality;

[0047] Step S3: A heavy-load bearing assembly 7 is installed on the top end face of the self-lubricating slider body 1. Since the bearing guard plate 71 is fixedly installed in the center of the top end face of the self-lubricating slider body 1, the buffer column 72 is installed around the top end face of the bearing guard plate 71, so that the load base frame 77 on the top of the buffer pressure rod 74 is located directly above the top of the bearing guard plate 71. The positioning screw holes on the end face of the positioning column 711 and the locking screw holes on the top of the locking plate 78 and the positioning plate 79 are used to facilitate the installation and positioning of the load structure, so that the heavy-load bearing assembly 7 can have a good load-bearing effect, thereby improving the load capacity of the self-lubricating slider body 1.
