The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0024] Embodiment 1:

[0025] Reference Figure 1-5 A small crawler crane wire rope maintenance device comprises a shell 1, an empty opening 101 is arranged in the shell 1, two sets of hydraulic rod devices 103 are arranged in the empty opening 101, and the telescopic ends of the hydraulic rod devices 103 are respectively fixedly connected with a clamping ring 1 201 and a clamping ring 2 202, and the clamping ring 1 201 and the clamping ring 202 are both provided with a spring chamber 203, and a spring member 204 is arranged in the spring chamber 203, and the two ends of the spring member 204 are respectively fixedly connected with the spring chambers 203 on the clamping ring 1 201 and the clamping ring 2 202, and an oil inlet pipe 3 is fixedly connected to the shell 1, and the oil inlet pipe 3 is fixedly connected to the hydraulic rod device 103, and the liquid outlet end of the oil inlet pipe 3 is used to spray the wire rope oil on the surface of the wire rope, The oil absorbing cotton 205 is fixedly connected in the clamping ring 1 201 and the clamping ring 202, the oil outlet pipe 301 is evenly fixedly connected to the liquid outlet end of the oil inlet pipe 3, and the nozzle 302 is fixedly connected to the liquid outlet end of the oil outlet pipe 301. The hydraulic rod device 103 includes a hydraulic rod body 104, an extrusion block 105, and a push rod 106. The hydraulic rod body 104 is fixedly connected in the outer shell 1, the extrusion block 105 is slidably connected in the hydraulic rod body 104, the push rod 106 is fixedly connected to the extrusion block 105, and the end of the push rod 106 away from the extrusion block 105 passes through the hydraulic rod body 104, and the through ends of the push rod 106 are fixedly connected to the clamping ring 1 201 and the clamping ring 2 202 respectively, and the fixed rod 102 is fixedly connected to the outer shell 1.

[0026] If the user needs to maintain the steel wire rope of the crane, the user can inject external steel wire rope oil through the oil inlet pipe 3. At this time, the hydraulic rod device 103 is affected by the steel wire rope oil, and the top rod 106 is extended, so that the clamping ring 1 201 and the clamping ring 202 are close to each other. At this time, the clamping ring 1 201 and the clamping ring 202 clamp the steel wire rope of the crane.
