Long-distance and large-diameter cable laying construction device and method in cable trough

Abstract

The invention relates to a long-distance and large-diameter cable laying construction device in a cable trough, which comprises a walking type lifting device, a lifting frame is arranged on the walking type lifting device in a lifting manner, and a flexible bottom supporting frame is detachably arranged on the lifting frame. The invention further discloses a long-distance and large-diameter cablelaying construction method in the cable trough. The device and the method have the following beneficial effects: firstly, a cable ground trough is formed in the ground through a ditching tool, a cableis laid beside the cable trough in the length direction of the cable trough, and the cable is laid on one side of the cable trough, so that mechanized operation is easier to realize; and according tothe long-distance and large-diameter cable laying construction device in the cable trough, the cable is transferred into the cable trough, and then the cable trough is backfilled with soil, so that the required labor force is reduced, the labor intensity is greatly reduced, the construction safety is improved, the operation method is simple, convenient and feasible, the popularization is easy, and greater economic benefits can be generated.

Description

technical field [0001] The invention relates to a long-distance and large-diameter cable laying construction device and a construction method in a cable trench, belonging to the technical field of cable construction. Background technique [0002] The laying of power cables in thermal power plants mainly includes power distribution rooms to major rotating machinery such as fans, coal mills, feed pumps, circulating pumps and corresponding MCC cabinets. The types of power cables mainly include: flame-retardant high-voltage power cables, fire-resistant low-voltage power cables, flame-retardant low-voltage power cables, etc. Since most of the power distribution room and the electrical equipment are connected through cable trenches, coupled with the large diameter of the power cable itself, the heavy weight per unit length, and the long laying distance of a single cable, the use of pure manual laying, especially the laying in the cable trench, is extremely inefficient. , If the m...

Problems solved by technology

Since most of the power distribution room and various electrical equipment are connected through cable trenches, coupled with the large diameter of the power cable itself, heavy weight per unit length, and long laying distance for a single cable, the construction efficiency of purely manual laying, especially in the cable trench, is extremely low. , if all manual laying has the disadvantages of high physical labor intensity and high cost, and it is difficult to achieve consistency in action when there are many construction personnel, the construction organization is relatively difficult, and the quality and safety of cable laying are difficult to guarantee. How to improve the performance of large-diameter cables Laying construction efficiency and laying quality have always been the focus of cable laying construction
