Cable protection device for taillight on rear leg of X-leg pump truck

Abstract

The invention discloses a cable protection device for the taillight on the rear leg of an X-leg pump truck, comprising a pump leg which is internally provided with an oil pipe. The outer side of the pump leg is fixedly connected with a taillight through a shock absorber. A cable is connected with a run-through protection pipe. The run-through protection pipe is fixedly connected with the pump leg.The run-through protection pipe is fixedly connected with a bent protection pipe. The bent protection pipe is fixedly connected with a linear protection pipe. The linear protection pipe and the oil pipe are fixedly connected with a clamping plate part. The clamping plate part is fixedly connected with the pump leg. The linear protection pipe and the bent protection pipe are arranged inside the pump leg to prevent the erosion of the cable by various substances inside the pump leg. The run-through protection pipe composed of a connecting pipe, a second spring, an outer cylinder, an inner cylinder, a steel ball and a hose is arranged at the place where the cable runs through the pump leg. The shock of the cable is absorbed by the cable. The rolling of the steel ball, the outer cylinder and the inner cylinder increases the rotation effect of the cable in the protection pipe and reduces the cable damage caused by rotation wear.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a taillight cable protection device on the rear legs of an X-type outrigger pump truck. Background technique [0002] The concrete pump truck is a machine that uses pressure to continuously transport concrete along the pipeline. It consists of pump body and delivery pipe. According to the structural form, it is divided into piston type, extrusion type and hydraulic diaphragm type. The pump body is installed on the chassis of the car, and then equipped with a telescopic or inflected boom, which constitutes a pump truck. The concrete pump truck is transformed from a truck chassis. It is equipped with motion and power transmission devices, Pumping and stirring device, distribution device and some other auxiliary devices. The power of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power tr...

Problems solved by technology

In the traditional technology, in order to protect the cable from being directly exposed to the air and prevent the cable from being eroded by various pollutants in the air, when designing the X-shaped rear outrigger structure of the pump truck, it is generally left inside the pump leg. Cable space, but the wiring arrangement of the cables inside the pump legs is disorderly and complex; the cables on the rear outriggers are protected by cable sleeves and fixed on the steel pipe with cable ties, but the city cable sleeves, cable ties Generally, it is made of plastic material. Due to the complex working environment of the pump truck, the pollutants in the air will be in contact with the cable sleeve and cable tie for a long time, which will cause the cable sleeve and cable tie to age rapidly, and cannot effectively protect and fix the cable. During the use of the car, the long-term bending and retracting of the pump legs will also cause the wear and tear of the cables, and the pump legs will be subject to other external impacts, and they will not be able to protect the cables well; the cable sleeves are assembled on the legs Unsightly and impractical
