Description
Technical Field
The invention relates to the technical field of elevators, in particular to a device for preventing an elevator from being ejected.
Background
An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical.
The most serious accident is that the elevator rushes to the top, namely the elevator rises quickly without control and collides with an elevator shaft. Therefore, there is a need for a device for preventing the elevator from impacting the top of the elevator car, so as to reduce the injury to passengers in the elevator car when impacting the top of the elevator car.
Disclosure of Invention
The invention aims to provide a device for preventing an elevator from impacting the top so as to reduce the damage to passengers when the elevator impacts the top.
In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a prevent device that elevator dashes top, includes the liquid case, and the liquid roof portion is equipped with out the liquid hole, and the intercommunication has the fluid-discharge tube on going out the liquid hole, and the top fixedly connected with hydrops case of fluid-discharge tube, the bottom of liquid case is equipped with a plurality of piston cylinders, equal sliding connection has the piston rod in every piston cylinder, the same fly leaf of bottom fixedly connected with of piston rod, many springs of fixedly connected with on the fly leaf.
The working principle of the invention is as follows: before use, the liquid box is filled with clear water, when the elevator is used, the liquid box is fixed at the top of an elevator shaft, a plurality of springs are vertically downward, if the elevator has top impact, when the elevator is in contact with the springs, the piston rod is connected to the bottom of the liquid box in a sliding manner, the bottom of the piston rod is fixedly connected with the same movable plate, the movable plate is fixedly connected with the springs, when the elevator is in contact with the springs, the springs begin to compress, the top impact speed of the elevator is reduced when the springs compress, the elevator continues to apply pressure to the springs when the springs compress, at the moment, the movable plate begins to push the piston rod to move towards the liquid box, when the piston rod moves, the water in the piston rod is pushed into the liquid box, as the liquid box is filled with clear water, the top of the liquid box is provided with a liquid outlet hole, and the liquid outlet hole is communicated with the liquid accumulating box through a liquid discharge pipe, because the piston cylinder is provided with a plurality of piston cylinders and only one liquid outlet hole is arranged, redundant water pushed into the liquid tank by the piston cylinder can be discharged out of the liquid tank through the liquid outlet hole, and because the liquid discharging speed of the liquid outlet hole is low, the water in the piston rod can only be slowly injected into the liquid tank, so the piston rod can only slowly move, and further the elevator is buffered.
The invention has the beneficial effects that: this scheme forms one section buffering through a plurality of springs to the elevator, slows down the speed of dashing of elevator earlier, then the cooperation of rethread piston rod and liquid tank forms two-stage buffer to the elevator, and the further speed of dashing of having slowed down the elevator, the effectual injury that can cause for the passenger when having reduced the elevator and dashing the top.
Furthermore, a transverse plate is vertically and slidably connected in the liquid tank, a plurality of through holes are formed in the transverse plate, and the transverse plate is fixedly connected with the plurality of piston rods. The hydraulic lifting device has the advantages that the transverse plate can be pushed to move in the liquid tank when the piston rod moves, the pushing speed of the piston rod when the piston rod is pushed by the elevator can be effectively reduced through the resistance of water in the liquid tank, and the pushing speed of the elevator is further reduced.
Furthermore, the number of the springs is nine, and the springs are arranged on the movable plate in a rectangular array. The purpose is to balance the stress and avoid the deflection by the arrangement.
Furthermore, the piston cylinder is nine, and the piston cylinder is the bottom of rectangle array at the liquid case. The purpose is to balance the stress and avoid the deflection by the arrangement.
Furthermore, one end of each spring, which is far away from the movable plate, is fixedly connected with a contact plate. The elevator car contact structure aims to increase the contact area of the spring and an elevator through the contact plate and avoid the spring from puncturing the elevator car.
Furthermore, each contact plate is fixedly connected with a rubber pad. Its purpose, through the flexibility of rubber pad increase contact plate, contact plate and elevator rigid contact when avoiding the elevator to dash the top.
