[0021] The folding plate 303 has a folding structure, and the wheel seat 304 and the guide wheel 305 are symmetrically distributed about the central axis of the folding plate 303.

[0022] In this embodiment, since the shock absorber 302 is arranged at the end of the fixed insert 301, and the shock absorber 302 and the folding plate 303 are distributed in a ring shape on the central axis of the hydraulic transmission mechanism 2, the shock absorption effect can be achieved to avoid damage to the equipment caused by excessive impact.

[0023] The arc strip 307 has an arc-shaped wave-like structure.

[0024] In this embodiment, the installed wheel seat 304, guide wheel 305 and the wave-shaped arc strip 307 can effectively transfer the impact object to the operating position, thereby achieving an effective protective effect and improving the safety of the equipment.

[0025] The base assembly 1 includes an assembly base 101, an external hinge seat 102, a movable base 103 and an assembly disk 104. The top side of the assembly base 101 is provided with the external hinge seat 102, and the inner side of the external hinge seat 102 is provided with a hinge-connected movable base 103, and one end of the movable base 103 is provided with an assembly disk 104.

[0026] In this embodiment, when in use, the assembly base 101 and the hinge base 208 are assembled in the use position. Since the external hinge seat 102, the movable base 103, the assembly plate 104 and the movable bar 207, the hinge base 208 are hingedly connected, the hinge transmission operation can be effectively performed.

[0027] The hydraulic transmission mechanism 2 includes an end plate 201, a cylinder body 202, a reinforcing rod 203, a sealing sleeve 204, a push rod 205, an end base 206, a movable bar 207 and a hinged base 208. The end plate 201 is bolted to one side of the assembly disk 104, and a ring-shaped reinforcing rod 203 is arranged below the edge of the end plate 201. The inner side of the end plate 201 is provided with a sleeve-mounted cylinder body 202.

[0028] In this embodiment, when it is needed, the cylinder body 202 on the inner side of the end plate 201 is used to output power to drive the output end to operate. When the output end in the cylinder body 202 is telescopically operated, it can drive the push rod 205 on the inner side of the sealing sleeve seat 204 to telescopically operate.

[0029] A sealing sleeve 204 which is bolted is arranged at the top of the oil cylinder body 202 , and a push rod 205 is arranged on the inner side of the sealing sleeve 204 , an end base 206 is arranged at one end of the push rod 205 , and one end of the end base 206 is hingedly connected to a hinged base 208 via a movable bar 207 .

[0031] The working principle of the hydraulic cylinder with a wear-resistant shell is as follows: when in use, the assembly base 101 and the articulated base 208 are assembled at the position of use. Since the outer articulated seat 102, the movable base 103, the assembly plate 104, the movable bar 207 and the articulated base 208 are hingedly connected, the hinge transmission operation can be effectively performed. When it is needed to be used, the cylinder body 202 on the inner side of the end plate 201 is used to output power to drive the output end to operate. When the output end in the cylinder body 202 is telescopically operated, it can drive the push rod 205 on the inner side of the sealing sleeve seat 204 to telescopically operate. When the push rod 205 is telescopically operated, the outer articulated seat 102, movable base 103 and end base 206, movable bar 207, hinged base 208 can achieve the effect of effective transmission operation, which is convenient for the efficient operation of the equipment. Since the shock absorber 302 is arranged at the end of the fixed insert strip 301, and the shock absorber 302 and the folding plate 303 are distributed in a ring shape on the central axis of the hydraulic transmission mechanism 2, the shock absorption effect can be achieved to avoid damage to the equipment caused by excessive impact. Moreover, the installed wheel seat 304, guide wheel 305 and the wavy arc bar 307 can effectively transfer the impact object to the operating position, thereby achieving effective protection and improving the safety of the equipment.
