Abstract

The invention relates to an unpowered down-going head-elevator with no need for an electric power drive transmission gear. According to the unpowered down-going hand-elevator, a kinetic energy device is removed from the traditional hand-elevator, a transmission device is simplified, and the frictional force is reduced. When the unpowered down-going hand-elevator runs, down-going power is provided by using geopotential of the human body; when the total geopotential of persons on the elevator is not enough to drive the elevator, the elevator is in a non-running state, and the elevator is used as a fixed stairway but cannot be used as an up-going stairway; and the geopotential of the persons on the elevator is large enough to drive the elevator to go down in an acceleration way, a hydraulic cylinder is driven to run; and when the speed is detected to be too high by a speed detection, a piston of the hydraulic cylinder is started to control waterflow to reach a deceleration effect. Therefore the electric power for driving the down-going hand-elevator can be eliminated, and the using cost is saved.

Description

Unpowered descending escalator

Technical field

At present, we need a large amount of electric energy to drive at the escalator that uses, even there are a lot of up-to-date technologys to join the energy-conservation the inside of staircase now, but just need to consume a large amount of electric energy as long as staircase moves.Usually descending more easily than up during stair climbing, perhaps just because this reason, descending escalator all can not see in often a lot of public arenas, even more subway station of the stream of people and pedestrian overpass etc.

Technical background

The purpose of this novel invention just provides a kind of descending escalator that does not need electric energy to drive operation, can reduce power consumption simultaneously, for people's trip brings convenience.

Summary of the invention

This novel invention mainly utilizes the gravitional force that weight produced of taking the people and goods on the down escalator, utilize this energy come in addition pedal to the pin along the supporting track in the staircase to lower slider.Pedal on the staircase and the pulley combination that the transmission gear in the two ends is formed about staircase, in descending process, the people on the dependence staircase or the gravitional force of object make it reach the result of downward operation.

Letting the gravitional force that stands in the people on the staircase drive pedal slides downwards; The friction force that at first will reduce in the operational process can move staircase more easily; Be once more when the stream of people is too much, the downward operating speed of gravitional force ambassador staircase is too fast will control its downstream rate.

The technical scheme that the present invention has solved technical matters is: it is too fast with the control downstream rate to reduce the friction force that produces in the operational process.Aspect the power of reducing friction; Compare with traditional escalator; At first to remove motor drive in staircase the inside with other and actuating device is relevant and can produce the apparatus of friction with the pedal running; Simplify the structure of pedal and supporting track and transmission gear, reduce the frictional loss energy of operation process.The below orbit of escalator transmits at two transmission gear intercropping straight lines up and down obliquely once more; The orbit up and down of traditional escalator pedal is parallel; At two ends up and down the operation parallel to the ground of one segment distance can be arranged all; Be that the pedestrian takes elevator for ease, this novel powerless escalator then changes the track of transmission on the lower direction into straight line obliquely, removes two ends structure parallel to the ground up and down; Just make pedal on lower direction, transmit the teacher and just reduced corner twice, thereby reduce the operation friction drag in pedal and the whole powerless escalator.Aspect control rate; This novel powerless escalator installs hydraulic actuating cylinder additional in two transmission gear the insides up and down does drag effect; The running of transmission gear rotating band hydrodynamic cylinder pressure; Speed detector detects the staircase running velocity, and the operating speed of modulated pressure cylinder is just controlled transmission gear again, thereby reaches the running velocity of the whole descending escalator of control.

The specific embodiment

Combine accompanying drawing through embodiment below, structure of the present invention is done further described.Angle of elevation by general existing escalator all is between 30 ° to 35 °; Be 35 ° of calculating like the elevation angle M of Fig. 1 and the elevation angle X of this novel unpowered escalator Fig. 2; It is as shown in the figure when the people stands on the down escalator; Receive the influence of people's gravitional force F, the power that produces the power F1 under oblique is 0.57 times that sin35 ° of F is about F.Therefore produce the speed V that slides downwards, and influenced by the people of staircase or the gravitional force F and the whole staircase pedal drive friction factor of object, therefore will reduce the operation friction force of unpowered escalator.As depicted in figs. 1 and 2; The 1st, the pedal below transmission track of traditional escalator; The pedal of novel unpowered escalator below transmission track 2 adopts straight lines load mode obliquely, adopts this mode can reduce M, a N corner, so pedal is littler than the gearing friction resistance of Fig. 1 during transmission on the lower direction in Fig. 2; Reduce the operation function of friction thereby reach, make the easier operation of powerless escalator ability.

In descending process; Excessive because of taking the passenger traffic flow of staircase, cause gravitional force F to strengthen gradually, F1 also can increase pedal will occur and constantly quicken descending simultaneously; For control rate; In the transmission gear 3 of staircase, install speed control hydraulic actuating cylinder gear 5 additional like Fig. 2, hydraulic actuating cylinder gear 5 is built on the transmission gear 3, drives 5 runnings of hydraulic actuating cylinder gear by transmission gear 3; Hydraulic actuating cylinder gear 5 is also turning round with same speed V when turning round with transmission gear 3 speed V, and operating speed receives 5 controls of hydraulic actuating cylinder gear simultaneously.Speed detector 20 as shown in Figure 3 is linked in the hydraulic actuating cylinder 5 through control line 21.Speed detector 20 reaches data in the piston 11 of hydraulic actuating cylinder 5 by control line 21, thereby control plunger 11 runnings are the running of modulated pressure cylinder gear 5.

Like Fig. 4 and shown in Figure 8, hydraulic actuating cylinder gear 5 is when doing clickwise, just piston 11 pressed downward, the water pressurized in the hydraulic cylinder 10 is discharged towards the drain gutter 12 of piston 11, and the size of drain gutter 12 directly has influence on the speed of piston 11 pressed downward.When 5 continuation of hydraulic actuating cylinder gear are rotated with speed V; Like Fig. 6 and shown in Figure 8; Piston 11 detaches from being forced into bottommost on the net; Make hydraulic cylinder 10 interior top water get in the cylinder body of below through the drain gutter 12 of piston 11 again, this process constantly continues again, and piston 11 is just constantly done to take out up and down and pressed work.The piston 11 that receives speed detector 20 controls is following three-deckers in going up; Like Fig. 7 and shown in Figure 9, drain gutter 12 is arranged in two-layer up and down 14, interlayer 15 is the key-course of drain gutter 12; Be built-in with motor 9 and built-in blade 13 at interlayer 15; Shown in figure 10, rotate the size that built-in blade 13 reaches control drain gutter 12 through motor 9, thus the running speed of control water velocity and control plunger.

The specific embodiment

When the people went on unpowered escalator, pedal will be slided downwards by gravitional force F effect, drove the running of transmission gear 3, and then drove 5 runnings of hydraulic actuating cylinder gear.When the rotative speed of transmission gear 3 is 0 or when low, speed detector 20 just by the motor 9 in control line 21 control plungers 11, then reaches maximum with the drain gutters 12 in the piston 11, to reduce staircase startup and running resistance.Rotative speed and the acceleration/accel that detects transmission gear 3 when speed detector 20 is during greater than a certain particular value; Through being started built-in blade 13, motor 9 dwindles the hole of drain gutter 12; Reach the running speed of control plunger 11, promptly controlled the operating speed of the unpowered hand steered ladder of bed rearrangement.

Let when unpowered escalator normal operation; When guaranteeing to have in the hydraulic actuating cylinder sufficient water and meeting emergency situation; Just start emergency reaction when not having the power supply supply or emergency situation takes place like speed detector 20; The stop device of putting by in the speed detector 20 slows down to put and stops, and the pedal of staircase can turn round yet and just became the fixedly effect of stair this moment, used up to recovering powerless escalator again.
