Mobile gate opening and closing device

Abstract

The invention discloses a movable gate starting and stopping device, comprising a hand cranking hoist, a transmission device I, a power device and a base; the base is fixed aside the hand cranking hoist through expansion bolts, the power device is mounted on the base, the power device comprises a gasoline engine, a single stage gearbox, a transmission device II, a floor stand, a crossbeam and a chassis; the floor stand is a quadrilateral fame and arranged on both sides of the chassis, the crossbeam is vertically connected to the floor stand, the floor stand, the crossbeam and the chassis form a rack, the gasoline engine and the single stage gearbox are mounted on the chassis, the single stage gearbox also comprises a forward power output shaft, a backward power output shaft, a coupler and a matching shafts. The coupler is mounted on a shaft end of the forward power output shaft, the movable gate starting and stopping device also comprises a tightness adjusting device I, and solves the problems that time and labor are consumed in manual starting of a hand cranking hoist, an electric hoist cannot be used without electricity and a motor is easy to steal.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a mobile gate opening and closing device. Background technique [0002] The hand hoist is also called the manual screw hoist. The general hand hoist includes a casing, a machine cover, a bracket, a nut, a screw, a large and a small bevel gear, a pressure bearing, a hand crank, etc. It is The hand crank is the power input device, which is connected with the input shaft of the hoist with a small bevel gear on it. It is a plane gate hoist equipment used for manual operation. It has a self-locking function, and the gate can stay at For any position, take a 15-ton hoist gate as an example: if the 15-ton gate hoist is opened and closed manually, 3 people need to take turns to drive the hoist by hand, and the screw goes up or down every 60 turns of the hoist. It takes 1.5 hours to open and close the gate once it drops by 1 centimeter, and manual driving is time-consuming ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the above-mentioned problems that the prior art manual hoist is time-consuming and laborious to open and close the gate, the ordinary electric hoist cannot be used in the case of inconvenient power connection, and the motor of the electric hoist is easy to be stolen, the present invention A mobile gate opening and closing device is provided
