Abstract
The invention discloses platform bridge lifting equipment without a power device. The technical scheme includes that the quantity and the total weight of pedestrians going up a platform bridge are unequal to the quantity and the total weight of pedestrians going down the platform bridge, and the pedestrians enter the equipment, so that the weight born by one end of the equipment is larger than the weight born by the other end of the equipment, one end of the equipment descends and drives the other end of the equipment to ascend, and the pedestrians can go up or down the platform bridge without the power device. The platform lifting equipment has the advantages that a damping effect is realized during ascending and descending, the speed is controlled, and the safety is guaranteed.
Description
1 technical field
What the present invention relates to is a kind of overline bridge jacking equipment of unpowered device, makes the crossover-passing pedestrian not use lifting overline bridge under the situations such as elevator.
2 background technologies
Along with the development of road traffic, the quantity of overline bridge is more and more on the urban road, and several overline bridges of the frequent high and low of pedestrian are very tired out, and the overline bridge that elevator is installed is also often stopped transport owing to cost and maintenance issues.
3 summary of the invention
At above problem, the present invention has announced a kind of overline bridge jacking equipment of unpowered device, and the pedestrian of convenient passing overline bridge is overline bridge up and down.
Technical scheme is to utilize at the every end of overline bridge the up-and-down situation of pedestrian to be arranged, can make this equipment that enters of up-downgoing number inequality, make: an end weight is greater than other end weight, thereby equipment one end descends and drives other end rising, finishes manned automatic lifting.
Equipment is equipped with damping unit, and moving resistance is set, and stablizes decrease speed, guarantees pedestrian's safety up and down.
Original state does not have the pedestrian, and equipment two ends wherein end deadweight are slightly larger than an other end, make equipment one end on overline bridge, and an end on the ground.
Can guarantee all pedestrians by overline bridge under this equipment, but can not guarantee that all pedestrians pass through overline bridge on this equipment that when a group traveling together wants to go up overline bridge, will not descend and there are other pedestrians on the overline bridge temporarily, then this people can only be by overline bridge on other mode.
Advantage of the present invention: be simple and easy to realize, unpowered device, running cost is cheap, makes things convenient for pedestrian's overline bridge up and down.
4 description of drawings
The front elevational schematic of Fig. 1 is unpowered device overline bridge jacking equipment
5 specific embodiment
As shown in Figure 1, hang casing (3) by pulley (1) rope (2) two ends, one of them casing (3) deadweight is slightly larger than another chest (3), then heavy one of two chests (3) on overline bridge (8), light one (9) on the ground.
The people of (9) will go up overline bridge (8) on the ground: enter the casing (3) that is positioned at the ground.
People at overline bridge (8) will descend ground (9): enter the casing (3) that is positioned on the overline bridge.
When on the overline bridge (8) casing (3) weight during greater than casing (3) weight of on the ground (9), in addition: on the ground
(9) the interior number of casing (3) can be zero, and the casing (3) that then is positioned on the overline bridge (8) moves down, and moves on the casing of (9) (3) on the ground.
Adopt air damping in this example, in gravity effect casing (3) moving process, casing (3) is fixedlyed connected with steel column (4), and steel column (4) pushes away/draw the air in mobile piston (5) the compression steel drum (6), produces moving resistance.Air in the steel drum (6) communicates by pore (7) and the external world, regulates the size of pore (7), can control the speed that casing moves.
Move after people in the casing (3) of overline bridge (8) comes out to finish, the people who is arranged in the casing (3) on ground can come out.This part people goes up overline bridge (8) like this, overline bridge (8) does not all need external device (ED) that power is provided down.
Claims (2)
1. unpowered device overline bridge jacking equipment, it is characterized in that: the people enters the one or both ends of this equipment, utilizes equipment one end weight greater than other end weight, moves up and down under unpowered device situation, and an end decline other end rises, and finishes manned lift.
2. unpowered device overline bridge jacking equipment according to claim 1 is characterized in that: be provided with damping, the control translational speed.
