10KV bypass cable overhead laying street crossing apparatus

Abstract

The invention provides a 10KV bypass cable overhead laying street crossing apparatus. The apparatus comprises a first supporting component, a second supporting component, two rod importing stands, a supporting rope, several mobile pulleys, a mobile pulley connection hauling rope and two infrared range finding alarms, wherein the first supporting component and the second supporting component have the same structure. The first supporting component comprises a pedestal, lifting rods and a driver. The two rod importing stands are arranged on upper ends of the two lifting rods. The supporting rope passes through the two rod importing stands and is used for supporting each mobile pulley. Each mobile pulley is used for supporting the bypass cable needing to carry out street crossing to carry out street crossing and can slide left and right replying on the supporting rope under traction of the mobile pulley connection hauling rope. The two infrared range finding alarms are fixedly installed on top ends of the two lifting rods respectively and installation directions are opposite. The structure of the apparatus is simple, the cost is low. The apparatus is portable and is convenient to use. Applicability is good. Repairing efficiency of a power supply department can be increased and working safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power distribution bypass operations, in particular to a street-crossing device for overhead laying of 10kV bypass cables. Background technique [0002] The bypass cable overhead laying bracket is one of the commonly used tools for the power supply department to carry out bypass operations. It is mainly used for laying bypass cables across the street during bypass operations. At present, the common overhead laying support for crossing the street is inconvenient to operate, and the on-site installation work is cumbersome. It requires high operating skills of the operators, and it cannot be automatically raised and lowered, which affects the efficiency of the bypass operation. For example, the Chinese patent document whose authorized announcement number is CN203747342U discloses an adjustable mobile cable overhead support device. It can effectively meet the actual needs of overhead laying of bypass cables ...

Problems solved by technology

At present, the common overhead laying support for crossing the street is inconvenient to operate, and the on-site installation work is cumbersome. It requires high operating skills of the operators, and it cannot be automatically lifted, which affects the efficiency of the bypass operation.

For example, the Chinese patent document whose authorized announcement number is CN203747342U discloses an adjustable mobile cable overhead support device. Effectively adapt to the actual needs of overhead laying of bypass cables across the street during power supply emergency repairs

The device that relies on electric tools to carry out overhead laying and maintenance of bypass cables is also currently being researched, such as the Chinese patent document with the application publication number CN103762520A, which discloses a kind of electric mobile platform for 10KV distribution line bypass operation, although it can Realize automatic lifting, but it is inconvenient to implement the cable crossing the street, and the structure is relatively complicated and the cost is high

[0003] In addition, in the actual operation process, since the bypass cable needs to be laid overhead to cross the street, it is inevitable that vehicles will pass under the erected bypass cable during construction. If a super-high vehicle passes close by, it is easy to hang up or pull away the overhead cable , prone to danger, so during the construction process, it is necessary to effectively monitor and warn the approaching of super-high vehicles to ensure the safety of the bypass operation, but the current common bypass cable overhead laying device does not have such a function
