Description

Traction device for high-rise fire rescue Technical Field The application relates to the field of high-rise firefighting rescue, in particular to a traction device for high-rise firefighting rescue. Background In large public buildings and high-rise buildings, a plurality of vertical shafts are arranged, such as elevators, cables (strong current, weak current) of pipelines (water, heating and air conditioning professions) and the like. The shaft runs through each floor, once the fire breaks out in a certain place, the shaft adjacent to the fire source can produce very big suction because of the hot pressing effect, makes the fire to receive along the floor and extends, causes personnel evacuation difficulty, and the passageway is stopped up, and firefighters are difficult to get into the scene of a fire and put out a fire. The direct loss of fire is casualties and property burning. Therefore, there is a need for a traction device for fire rescue designed for large high-rise buildings. In the existing high-rise fire rescue device, for example, chinese patent with the publication number of CN 112007290B discloses a high-rise fire rescue device, specifically, a transverse plate is fixed on a top building, a guide plate extends to the outside of a building, a binding rope is tied on a rescue person and is fixed, a pressing block is pressed inwards by hands until clamping saw teeth are separated from a safety rope, the pedal is stepped on by feet, a control ring is loosened by hands until the top extends to the outside of the building when the high-rise fire rescue device is about to reach a designated position, the pressing block is not pressed by hands any more and then is pushed by a powerful spring to push a semicircular ring to press the clamping safety rope to stop falling, the rescue person continues to descend due to inertia pulling of a buffer ring, and the buffer block presses the buffer spring until the buffer block slides to the top of a buffer groove. The fire rescue function to the high-rise building can also be realized to above-mentioned prior art, but on the one hand, above-mentioned prior art needs a large amount of manual work to assist in the in-process of fire rescue, has prolonged fire rescue's time, and on the other hand, above-mentioned prior art does not consider the personal safety of rescue personnel, easily causes the phenomenon that the rescue personnel falls aloft, based on this, still has improvement space on the basis of current high-rise fire rescue device. Disclosure of Invention The application provides a traction device for high-rise fire rescue, which can realize the fire rescue function of a high-rise building. The application provides a traction device for high-rise firefighting rescue, which adopts the following technical scheme: the utility model provides a high-rise fire rescue is with draw gear, includes push module, support module and traction module, its characterized in that, push module is rectangular structure, and push module quantity is two, and support module is installed to push module lower extreme, installs traction module between two push modules. The pushing module comprises a pushing plate, a sliding groove, a threaded column and a supporting rod, wherein the sliding groove is arranged on the inner side of the pushing plate, the supporting rod is symmetrically arranged inside the sliding groove, the threaded column is arranged between the supporting rods and connected with the inner wall of the sliding groove through a bearing, the end part of the threaded column is connected with an output shaft of the motor, and the traction module is connected with the threaded column and the supporting rod respectively. Through adopting above-mentioned technical scheme, the starter motor, screw thread post begins to rotate, and the screw thread post drives and pulls the module and remove, and the bracing piece prevents that the module from taking place the skew at the in-process that removes, and then realizes pushing module's propelling movement function. The support module comprises a fixed plate and a tightening unit, the fixed plate is arranged at the middle part of the lower end of the pushing module, the tightening unit is arranged on the right side of the lower end of the pushing module, and a clamping groove is formed between the tightening unit and the fixed plate. Through adopting above-mentioned technical scheme, span push module in high-rise window both sides, inwards extrude through tightening the unit, realize tightening the unit and press from both sides tight function to the wall body, make push module can be steady span on high-rise window simultaneously. Traction module is including rotating motor, winding wheel, protective belt, protection unit and standing board, and the motor cabinet is installed to push away board outside right-hand member, and push away inboard right-hand member of board is provided with the winding wheel, and the winding wheel i
