Abstract

The invention belongs to the tunnel construction field and discloses a cable laying traction device in a tunnel. The device comprises a device pedestal, guide mechanisms, a traction mechanism and a speed measurement component. The two guide mechanisms are fixedly installed at left and right ends of a traction device main body. The traction mechanism is arranged between the two guide mechanisms andis movably installed on the device pedestal through a friction force adjusting mechanism, and a cable enters from one guide mechanism, penetrates through the speed measurement component and the traction mechanism and then leaves from the other guide mechanism. The friction force adjusting mechanism comprises an upper pedestal, an electromagnetic telescopic column and a sliding block. The upper pedestal is fixedly arranged above the device pedestal, two sliding grooves are arranged on an upper surface, a bottom of the traction mechanism is fixedly connected with tops of sliding blocks arrangedin the sliding grooves, one end of the electromagnetic telescopic column is fixedly connected with the device pedestal through a connecting mechanism, and the other end of the electromagnetic telescopic column is fixedly connected with a side surface of a speed reducer. In the invention, a traction speed of a cable can be ensured, and cable laying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel cable construction, in particular to a traction device for cable laying in a tunnel. Background technique [0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable route. According to the application occasion, it can be divided into several laying methods such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Reasonable selection of cable laying method is very important to ensure the transmission quality, reliability and construction maintenance of the line. [0003] Due to the very humid environment in the tunnel, it is very easy to cause the surface of the cable to become wet, which in turn weakens the frictional traction force of the friction wheel in the cable laying traction device to the cable, resulting in a decrease in the cable laying traction speed and work efficiency. Secondly, the frictional tr...
