[0002] In order to keep the lifting equipment in good operating condition, the operation and maintenance unit needs to perform regular maintenance. In order to ensure the safe operation of the wire rope, the wire rope on industrial equipment must be lubricated and maintained regularly.

DETAILED DESCRIPTION
[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
[0028] like Figure 1 to Figure 3 As shown, the displacement mechanism of the wire rope lubrication device of this embodiment includes a crawling base plate 1, and a crawling cylinder 2 and a solenoid valve 3 are arranged on one side of the upper surface of the crawling base plate 1, and the solenoid valve 3 is electrically connected to the crawling cylinder 2. Clamping crawling units 4 are symmetrically arranged on both sides of the upper surface of the crawling base plate 1, and the clamping crawling units 4 located on the same side as the crawling cylinder 2 are connected to the piston rod of the crawling cylinder 2. The clamping crawling units 4 connected to it are driven by the crawling cylinder 2, so that the group of clamping crawling units 4 is close to the other group of clamping crawling units 4 arranged opposite to it, and the symmetrically arranged clamping crawling units 4 cooperate to achieve the clamping and loosening of the wire rope. An autonomous crawling module slide 5 and an autonomous crawling module frame shell 6 are fixedly arranged on the upper surface of the crawling base plate 1, and the autonomous crawling module slide 5 and the autonomous crawling module frame shell 6 respectively protect the two groups of clamping crawling units 4 on both sides of the upper surface of the crawling base plate 1. The outer sides of the autonomous crawling module sliding cover 5 and the autonomous crawling module frame shell 6 are both provided with autonomous crawling module side end handles 7, and the connection between the autonomous crawling module and the lubrication and cleaning module is achieved through the autonomous crawling module side end handles 7.
[0029] Specifically, the crawling cylinder 2 is provided with two groups on one side of the upper surface of the crawling base plate 1, and the clamping crawling unit 4 is provided with two groups on the same side of the crawling base plate 1. A total of four groups of clamping crawling units 4 are provided on the crawling base plate 1, and the two groups of clamping crawling units 4 close to the crawling cylinder 2 are respectively connected to the piston rods of the two groups of crawling cylinders 2. The clamping crawling unit 4 includes an electric motor 41, a transmission gear set 42 and a power wheel frame 43. The electric motor 41 is fixedly provided on the crawling base plate 1, and the transmission gear set 42 is provided corresponding to the output shaft of the electric motor 41. The power wheel frame 43 is fixedly provided on the crawling base plate 1. Two groups of power wheels 44 are rotatably provided on the power wheel frame 43, and the rotation direction of the two groups of the power wheels 44 is the same, and the power wheels 44 are connected to the transmission gear set 42. Under the driving action of the electric motor 41, the power wheel 44 can be driven to rotate through the transmission of the transmission gear set 42, and the rotation of the power wheel 44 can enable the autonomous crawling module to realize self-help crawling along the wire rope.
[0030] The utility model works specifically as follows:
[0031] 1) The utility model includes a total of four groups of clamping crawling units 4, of which two groups of clamping crawling units 4 located on the same side are respectively close to the two groups of clamping crawling units 4 on the other side corresponding thereto under the control of two groups of crawling cylinders 2, and the clamping and loosening of the wire rope by the clamping crawling units 4 is realized through the control of the crawling cylinders 2. At present, in the loosened state, the maximum spacing between the power wheels 44 is 80mm, and the diameter range of the wire rope that can be adapted during normal use is 60 to 80mm. When in the clamped state with the wire rope, the contact length between the power wheel 44 and the wire rope is 330mm. The longer contact area makes the overall operation of the robot more stable and reliable when the robot and the wire rope are in the clamped state and the robot is in the powered crawling state.
[0032] 2) When the power wheels 44 on both sides of the crawling base 1 clamp the steel wire rope, the four groups of electric motors 41 of the clamping crawling units 4 rotate forward and reverse, and the driving transmission of the transmission gear set 42 drives the power wheels 44 to realize the corresponding reverse rotation, thereby controlling the advance and retreat of the utility model on the steel wire rope. The crawling speed of the robot on the steel wire rope is controlled by a synchronous motor, with a maximum climbing speed of 10m / min and a maximum descending speed of 15m / min.
[0033] 3) The utility model has a small size and a large load capacity, with a total weight of 16kg and a load capacity of up to 120kg. It also has a synchronous auxiliary pipeline winding unit to achieve synchronous winding or release of a 130-meter combined pipeline during the robot's crawling process.
[0034] 4) The overall design of the utility model is modularized, which enables two or more robots to lubricate at the same time and improves the efficiency of lubrication. The hardware structure design and software program control functions are modularized, which facilitates the input and output of each hardware device and functional module of the robot, and realizes the input and output of each corresponding adaptive software control function.
[0035] 5) The utility model can be used as a carrying platform, and can carry standardized oil injection modules or other operating modules (such as wire rope flaw detection, camera and other functions) in both directions along the wire rope, so as to realize bidirectional lubrication of the wire rope in the vertical direction without being restricted by the lubrication direction.
[0036] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
