Simple contact net constant-tension wire barrow

Abstract

The invention provides a simple contact net constant-tension wire barrow which is provided with a barrow frame. Barrow hook buffer devices, steering racks, a brake system and an electric system are arranged on the barrow frame. A constant-tension pay-off device is arranged on the upper end face of the barrow frame and comprises bobbin loader devices, tensioners and tension increasing disc devices. The four sets of bobbin loader devices are arranged at the I position ends of the barrow frame. The two sets of tensioners and the two sets of tension increasing disc devices are arranged at the II position ends of the barrow frame. The bobbin loader devices and the tensioners are arranged in sets. The constant-tension pay-off device drives the bobbin loader devices and the tensioners to generate pay-off tension through a hydraulic pump. The constant-tension pay-off device makes the pay-off tension constant through a tension control system. A tension detecting system is arranged on each tensioner. The tension detecting systems and the tension control system control and display pay-off tension parameters through a tension control panel. By means of the simple contact net constant-tension wire barrow, the pay-off tension is improved and is constant, the pay-off tension parameters are displayed in real time, and the simple contact net constant-tension wire barrow has the advantages of being minimized in wire outlet angle, high in pay-off quality and pay-off efficiency, low in manufacturing cost, good in cost performance and the like.

Description

technical field [0001] The invention belongs to the technical field of railway engineering machinery, in particular to a simple catenary constant tension pay-off vehicle. Background technique [0002] With the rapid development of the operating mileage of electrified railways, the operating speed of railway operating vehicles continues to increase, and the requirements for catenary power supply technology are also getting higher and higher. Traditional catenary wire-releasing vehicles can no longer meet the requirements of wire-laying construction operations and line maintenance. Require. At present, the traditional pay-off car has the following four obvious deficiencies. First, the pay-off tension is not constant, which belongs to variable tension pay-off. The pay-off tension gradually increases from small to large between 6kN and 17kN; second, the pay-off tension is insufficient. The pay-off tension at the initial stage is less than 10kN; the third is that the pay-off ten...

At present, the traditional pay-off car has the following four obvious deficiencies. First, the pay-off tension is not constant, which belongs to variable tension pay-off. The pay-off tension gradually increases from small to large between 6kN and 17kN; second, the pay-off tension is insufficient. The pay-off tension at the initial stage is less than 10kN; the third is that the pay-off tension cannot be displayed in real time, and the real-time pay-off tension cannot be effectively controlled; the fourth is that there is no pay-off centering function, and the outlet angle cannot be reduced to Minimized, poor pay-off quality

The constant tension pay-off car imported from abroad has superior performance and leading technology, but the equipment cost is high and the cost performance is poor.
