Cable laying side pressure monitor and cable turning laying equipment

Abstract

The invention discloses a cable laying side pressure monitor and belongs to the technical field of cable laying equipment. The cable laying side pressure monitor comprises a signal collection mechanism and a signal processing mechanism, wherein the signal collection mechanism comprises a pressure sensor; the pressure sensor is mounted on a base on which the lateral idler wheel of a turning pulley is positioned; the signal processing mechanism comprises a signal processing device, a signal outputting device and a power supply which are connected with one another; and the pressure sensor is electrically connected with the signal processing device. The invention further discloses a cable turning pulley; and the cable laying side pressure monitor is mounted on the cable turning pulley base. The technical scheme is as follows: the pressure sensor arranged on the cable turning pulley base can monitor the lateral pressure of a cable in real time; and meanwhile, a detector has an automatic alarming function when the lateral pressure is too great. Illegal operation in a cable laying process can be avoided, the cable laying quality is improved and the cable fault rate is reduced; and the economic loss caused by the quality problem of laying construction is reduced, and the safe and stable operation of a high-voltage cable is guaranteed.

Description

technical field [0001] The invention relates to a device for cable laying, in particular to a cable laying side pressure monitor and cable turning and laying equipment. Background technique [0002] With the upgrade of urban power grid transformation, the degree of urban power grid cable is getting higher and higher, and the role of cables in the power grid is becoming more and more important. High voltage cables tend to bend under lateral pressure during laying. When bending, the cable is stretched on the outside and squeezed on the inside. Due to the cable material and structural characteristics, the cable has a certain limit to the lateral pressure. When the lateral pressure is too large, it will cause damage to the insulation layer and the sheath, which will bring major safety hazards to the operation of the high-voltage cable line. Severe cases may even cause excessive lateral pressure at the turning, exceeding the lateral pressure that the cable can withstand, result...

AI Technical Summary

Problems solved by technology

[0003] In the past, during the cable laying construction process, the control of the side pressure of the cable was more based on the work experience accumulated by the construction personnel for many years, and it was impossible to accurately detect the side pressure on the actual cable during the laying process.

This kind of construction process of cable laying based on experience does not meet the strict requirements of cable laying, and the construction process is prone to non-standard, non-standard and unsafe places.

If the side pressure is too large during the laying process, there is no overvoltage alarm device to remind the construction personnel to stop laying the cable immediately. Continuing the construction will cause irreparable damage to the cable construction, and it is necessary to replace the cable in the faulty section and reinstall it laying, thereby delaying the cable construction process and greatly increasing the construction cost
