The bracket is used for connecting a fixed guide rail; the four guide rails are fixed on two sides of the shaft; the lifting platform is arranged between the guide rails; the base of the hydraulic cylinder is fixed on the ground, and the piston rod is connected with the lifting device; the lifting device is provided with a chain wheel at the upper side, a pulley at the lower side, two guide wheels I and II at two ends respectively, and the two guide wheels I and II are distributed in an up-and-down symmetrical manner, and the lifting device moves along the guide rail under the jacking action of the hydraulic cylinder; one end of the chain is fixed on the lifting platform, and the other end of the chain bypasses the chain wheel and is fixed on the bracket; one end of the steel wire rope is fixed on the lifting platform, and the steel wire rope bypasses the other end of the pulley and is fixed on the support.
The locking device is arranged at the bottom of the lifting platform and consists of an electric cylinder and a locking mechanism, and the locking mechanism is a combination of a long rod and four crank block mechanisms. The piston rod of the electric cylinder is hinged with the long rod.
Compared with the prior art, the invention provides a hoistway lifting operation platform with a flat-bed locking device, which has the following beneficial effects:
1) the device has simple structure and small occupied space, and greatly increases the utilization efficiency of the well space;
2) the driving force of the lifting device is provided by the hydraulic pump and the four hydraulic cylinders, the lifting capacity of the device is high, and the lifting process is stable;
3) the hoisting load is mainly born by the chain, and wire rope plays the guard action, increases hoisting system's security, through 1: 2, the rope winding ratio is arranged at the positions of the chains and the steel wire ropes, so that the stroke of the lifting platform is twice that of the hydraulic cylinder, and the height which can be reached by the platform is increased;
4) the locking device is installed to lift platform bottom, and after lift platform reachd the flat bed, locking device can fix lift platform on the guide rail, makes the platform remain stable when loading and unloading, avoids the pneumatic cylinder to receive impact load, plays the effect of protection pneumatic cylinder simultaneously.
