Description

Postposition filling type household elevator

Technical Field

The invention relates to a rear-mounted filling type household elevator, and mainly relates to the field of elevators.

Background

The elevator is a perfect transportation device, and adopts various safety measures to eliminate potential safety hazards such as falling, top rushing and the like. As long as the elevator is used correctly and maintained and checked regularly, no safety accident occurs. The main safety protection device comprises a speed limiter, a safety clamp and a buffer. The buffer is arranged at the bottom of the elevator shaft, and when the elevator is downwards contacted with the buffer, the elevator can be prevented from being contacted with the ground. The existing elevator buffering is implemented by adopting a spring for buffering, the elastic coefficient of the spring is theoretically unchanged, the spring is required to provide enough supporting force during maintenance at ordinary times, and the supporting force is required to be weakened properly when buffering is implemented so as to have enough compression stroke and reduce the impact on an elevator body. Therefore, it is difficult to consider both the above two usage scenarios with a simple spring.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the rear-mounted type home elevator, so that when an internal contact plate is impacted greatly enough, the sliding pin can puncture the isolation layer, and further the air in the internal contact plate is communicated with the outside, the inner cylinder and the outer cylinder can obtain larger contraction distance, the impulse borne by the elevator body is reduced, the buffering effect is achieved, and the use scenes of normal maintenance and buffering can be considered.

In order to achieve the purpose, the technical scheme of the invention is as follows: the elevator comprises an elevator body and a buffer device, and is characterized in that the buffer device comprises an outer cylinder, an inner cylinder and a trigger component; the inner cylinder is sleeved in the outer cylinder, the upper end of the inner cylinder extends upwards from the upper opening of the outer cylinder, a first spring is arranged in the outer cylinder, and the upper end and the lower end of the first spring are respectively abutted against the lower end of the inner cylinder and the lower end of the outer cylinder; the trigger assembly comprises a supporting plate, a second spring, a sliding pin, a contact plate and an isolating layer; the support plate is horizontally arranged at the upper part in the outer barrel, the support plate is provided with a sliding hole and an air outlet hole which are communicated with the inside and the outside, the sliding pin is vertically matched in the sliding hole in a sliding manner, the upper end of the sliding pin extends out of an upper barrel opening of the inner barrel, the contact plate is fixed with the upper end of the sliding pin above the inner barrel, the isolation layer is positioned below the support plate, the second spring is sleeved outside the sliding pin, the upper end and the lower end of the second spring are respectively abutted against the upper surface of the support plate and the lower surface of the contact plate, and the inner barrel is isolated up and down by the isolation layer; when the pressure borne above the contact plate is larger than a set value, the lower end of the sliding pin slides downwards to puncture the isolation layer.

The technical principle and the beneficial effects of the invention are as follows:

outer cylinder and inner tube sliding fit in this scheme are equipped with first spring in the urceolus simultaneously, and the inside gas of first spring and urceolus inner tube of here can play certain cushioning effect when receiving the impact for the inner tube upper end.

When the contact plate is pressed downwards, the sliding pin is driven to slide downwards, when the elevator body normally runs and is in contact with the contact plate, the pressure applied to the contact plate by the elevator body is not enough to drive the sliding pin downwards to puncture the isolation layer, the pressure applied to the contact plate is below a set value, the spaces inside the inner cylinder and the outer cylinder are independent, the outer cylinder and the inner cylinder contract to compress air, but because the internal gas is unchanged, if the internal gas does not flow to the outside, the contraction distance between the outer cylinder and the inner cylinder is difficult to continue to compress when reaching a certain range; however, if the elevator is out of control and slides downwards at an excessively high speed, the pressure drop applied to the contact plate by the elevator body is larger than a safety set value, and the contact plate drives the sliding pin to puncture the isolation layer downwards. In case the isolation layer is punctured, the enclosure space that inner tube and urceolus formed will be in outside intercommunication, and inside gas can outwards release, and the inner tube gliding distance just can the grow downwards, and relative contact plate will diminish to the reverse impulse of elevator body, and then realizes the protection to the elevator body.

Because the existence of isolation layer, too fast and bump the contact plate when elevator body falling speed for when inside contact plate receives enough big impact, the spacer will be punctured to the sliding pin, and then makes inside air intercommunication outside, and consequently inner tube and urceolus will obtain bigger shrink distance, reduce the impulse that the elevator body received, in order to play the effect of buffering.

When overhauing, the isolation layer does not puncture, and the inside first spring of inner tube and urceolus and air provide the support simultaneously, and holding power can be bigger, and the isolation layer is punctured when the buffering, and inside air can slowly flow out, and the holding power that provides is littleer, consequently can compromise the use scene of overhauing at ordinary times and buffering

Preferably, the isolation layer with the interval is left to the backup pad, the top of isolation layer is equipped with the limiting plate of the deformation volume that the control isolation layer upwards is outstanding, and this limiting plate avoids the isolation layer to be in because of deformation damage before the contact plate does not reach the setting value, the limiting plate corresponds the lower extreme of sliding pin is equipped with the window, also can make inside air receive certain compression when elevator is normal at ordinary times and the contact plate collides, props the isolation layer bad when the existence of limiting plate can avoid inside air compression.

Preferably, the upper surface of backup pad is equipped with the slide cartridge, the lower extreme of slide cartridge with the window butt joint, the upper end of slide cartridge is located below the last tube socket of inner tube, sliding pin sliding fit in the slide cartridge, the microphone can be for the slide pin effect that provides the direction that slides from top to bottom.

Preferably, the last nozzle of urceolus inwards is equipped with spacing platform, sliding fit has the piston board in the urceolus, the lower extreme of inner tube with the piston board is fixed, the piston board is equipped with the connecting hole of intercommunication urceolus and inner tube, and the slip of the relative urceolus of inner tube can be avoided in the cooperation of spacing platform and piston board.

Preferably, the outer cylinder is located below the ground, after the inner cylinder completely slides into the outer cylinder, the ground which is in contact with the elevator body is the ground, and because the contact area is large enough, and meanwhile, the impulse of the elevator body is sufficiently eliminated by the inner cylinder in the earlier stage, the downward sliding action of the elevator body by the ground can be smoothly stopped, and the situation that the outer cylinder is located on the ground and generates overlarge pressure on the elevator is avoided.
