Embodiment

[0024] An embodiment of a protective device for preventing line from coming out of the present invention, such as Figure 1 to Figure 3 As shown, the mounting frame 2 is a U-shaped curved plate, and the mounting frame 2 is horizontally provided with a roller 1, which is sleeved on the fixed shaft 10 and fixed on the arm body through the fixed shaft 10.

[0025] see image 3 As shown, bearings 12 are installed at both ends of the roller 1 to enhance the bearing capacity, and a lengthened spacer 11 is reinforced between the two ends of the bearings 12 to act as a positioning bearing 12, and spacers 7 are installed at both ends of the roller 1 to act as the roller 1 and the fixed shaft 10. The positioning function ensures that the roller 1 does not interfere with the mounting frame 2 to ensure smooth rolling; in order to ensure that the mounting frame 2 is not deformed when it is connected with the corresponding parts, a reinforcing sleeve and a connecting plate are added to it. ...

Abstract

The invention discloses a protection device for preventing a circuit from being disconnected. A roller is arranged on an installation rack, a plurality of rope grooves are formed in a circumferentialsurface of the roller, a support plate is arranged below the roller along an axial direction, a plurality of partitioning plates are arranged on the support plate at intervals, partitioning grooves are formed between adjacent partitioning plates and are corresponding to the rope grooves in one-to-one correspondence, fracture surface sealing is formed among the partitioning grooves, the rope grooves and the support plate, a plurality of auxiliary driving wheels are arranged aside the partitioning grooves and are corresponding to the partitioning grooves, and the plurality of auxiliary driving wheels are connected in series by a first pin shaft. In the protection device, a pipe and a circuit are partitioned by partitioning plates, partitioning spaces are longitudinal surfaces, a tension buffer space is reserved for the loosen pipe and the loosen circuit, the pipe and the circuit are positioned and are not deviated towards two sides during travelling by the auxiliary driving wheels, and the pipe line can be prevented from being separated from the grooves under an impact load.

Description

technical field [0001] The invention relates to a protection device for preventing line from falling out, which is suitable for the protection device of internal pipeline and line arrangement in the form of telescopic booms or outriggers of high-altitude operating vehicles and truck-mounted cranes. Background technique [0002] The telescopic structure of booms or outriggers such as aerial work vehicles and truck-mounted cranes involves pipelines or lines running inside the arm body, which requires that the pipes and lines can walk synchronously when the boom or outriggers are stretched It is realized by arranging pipes and lines with special drag chains, but it takes up a lot of space and costs high. [0003] Since the arm frame or legs are stretched and retracted, steel wire ropes or chains are used to pull the arm body, so there is a necessary structure, and the pipes and lines are arranged to follow the shrinkage chain and wind around a moving pulley to realize the trans...
