Problems solved by technology

In the prior art, the drilling and blasting method is usually used to excavate the tunnel. In a high-altitude environment, the internal combustion engine equipment is prone to a sharp drop in power due to insufficient fuel combustion, resulting in an increase in fuel consumption, and the exhaust gas emitted by the equipment is toxic. Harmful substances have increased significantly, which has greatly affected the overall efficiency, quality and safety of tunnel construction operations

Abstract

The invention discloses an external cable follow-up device for electrical transformation equipment for tunnel excavation, and relates to the technical field of power supply of the electrical transformation equipment. The external cable follow-up device comprises a winding and unwinding device and a weight measuring device, the winding and unwinding device comprises a winding drum, a motor and a counter, the motor is used for driving the winding drum to rotate, a counting hole is formed in the winding drum, the counter is used for counting when the counting hole rotates over the position of the counter, a force measuring device comprises a weighing device and a bearing roller, the bearing roller is rotatably arranged at the top of the weighing device, a cable is arranged on the winding drum in a winding mode, a position, close to one end connected with the electrical transformation equipment, of the cable is arranged on the bearing roller, the weighing device is used for detecting downward pressure applied to the weighing device by the bearing roller and a power transmission section, the external cable follow-up device further comprises a controller, and the weighing device, the counter and the motor are all electrically connected with the controller. The external cable follow-up device is mainly used when a tunnel is excavated by a drilling and blasting method for deslagging, the external cable of the electrical transformation equipment can be automatically wind and unwind along with the reciprocating movement of the equipment, and electric shock accidents caused by the fact that the cable is dragged to be damaged or the cable is wound into a chassis are avoided.

Description

technical field [0001] The invention relates to the field of power supply for electric reforming equipment, in particular to an external cable follower for electric reforming equipment for excavating tunnels. Background technique [0002] Affected by complex terrain conditions and harsh natural environment, it is inevitable to build a large number of tunnels when building high-altitude railways and highways. Influenced by special construction conditions such as complex geological conditions and fragile ecological environment, its construction is extremely difficult. In the prior art, the drilling and blasting method is usually used to excavate the tunnel. In a high-altitude environment, the internal combustion engine equipment is likely to suffer from insufficient fuel combustion, resulting in a sharp drop in equipment power, increased fuel consumption, and poisonous exhaust gas emitted by the equipment. Harmful substances have increased significantly, which has greatly aff...
