Safety supervision system for electric trolley on construction site

Abstract

The invention relates to the technical field of construction equipment, in particular to a construction site electric trolley safety supervision system which comprises a supporting frame, a hopper and a power assembly, the supporting frame is horizontally arranged, the hopper is arranged on one side of the upper end of the supporting frame through a hinge, and the device controls up-down movement of a movable plate through a pressurizing tank; when the electric trolley runs to a stop position, the mounting seat is in contact with the buffer column, a safety rod arranged at the lower end of the buffer column is inserted into a safety groove of the moving shaft, rotation of the moving shaft and the moving wheels is limited, and the use safety coefficient of the electric trolley is enhanced; the movable plate is connected with the mounting base through a plurality of buffer plates and buffer rods, in the running and using process, shaking of the supporting frame is buffered through springs connected to the buffer rods in a sleeving mode, vibration damage of electrical components on the trolley is reduced, the service life is prolonged, safety is improved, and meanwhile operation is easy and use is convenient.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a safety supervision system for an electric trolley on a construction site. Background technique [0002] With the increase of high-rise buildings, in order to better reduce costs and increase efficiency, and protect the environment, more and more small electric tricycles are used on construction sites to transport construction materials such as mortar. When electric machinery enters the elevator, it is often due to the operation The carelessness of personnel, untimely maintenance of mechanical equipment, negligence and paralysis, make the mechanical vehicle suddenly hit the safety protection door during the operation of the people-goods elevator, resulting in the occupants in the people-goods elevator box being unable to escape in time. The electric trolley is equipped with signal receiving and generating blocks respectively. When the trolley is completely in the ...

Problems solved by technology

[0002]With the increase of high-rise buildings, in order to better reduce costs and increase efficiency, and protect the environment, more and more small electric tricycles are used on construction sites to carry out construction materials such as mortar When the electric machinery enters the people-freight elevator, it is often due to the carelessness of the operator, the untimely maintenance of the mechanical equipment, and negligence and paralysis, which make the mechanical vehicle suddenly hit the safety protection door during the operation of the people-freight elevator, causing the people-freight elevator box The occupants in the body cannot escape in time. In the prior art, the signal receiving and generating blocks are respectively set in the elevator and the electric trolley. When the trolley enters the elevator completely, the trolley is powered off through the software system. At the same time, there is still a certain degree of instability, so there are still problems that need to be improved in the use of electric trolleys
