Automatic roadblock placing device

Abstract

The invention discloses an automatic roadblock placing device in order to solve the problems that a roadblock cannot be fully automatically and efficiently placed and control logic is tedious in the prior art. The automatic roadblock placing device comprises a vehicle body. An electric cylinder and a first motor are fixed to the top of a main body of the vehicle body. Wheels and axles are arrangedat the bottom of the vehicle body. A bottom board is arranged in the vehicle body. A second motor and a first gear are arranged on the upper side of the bottom board. The first gear is engaged with achain. The chain is engaged with a second gear. The second gear is arranged at the end of an input shaft of a speed reducer. An output shaft of the speed reducer drives a second rotary shaft and a second friction barrel to rotate. The second friction barrel makes contact with a conveyor belt and drives the conveyor belt to move. Multiple fixed magnetic discs are arranged on the upper side of theconveyor belt and attract a lower magnetic board at the bottom of the roadblock. A longitudinal rod is driven through motion of the electric cylinder, an attraction magnetic disc attracts an upper magnetic board at the top of the roadblock, so that an automatic roadblock placing function is achieved, application and popularization of the device are facilitated, and meanwhile the achieving cost isreduced.

Description

technical field [0001] The invention belongs to the field of road administration engineering, in particular to a device for automatically placing roadblocks. Background technique [0002] Barricades refer to obstacles placed on the road. Roadblock is a kind of facility for road traffic isolation and warning. It is generally used for temporary isolation and division of road maintenance construction. With the rapid development of my country's transportation industry, the new situation has higher and stricter requirements for the layout of roadblocks. [0003] At present, in the maintenance of domestic traffic roads, the roadblocks are mainly arranged manually, that is, the operators place the roadblocks one by one to the designated position on the traffic. This way of roadblock arrangement leads to a long time-consuming and uneven layout And there are hidden dangers of traffic accidents for operators.
