Abstract
The utility model discloses a chain loosing detection device, belonging to the field of a weight hoisting safeguard protection device. The device comprises an outer casing and a microswitch, wherien a switch support and a cover plate are connected on the outer casing, a limiter composed of a slide block, a connection shaft, a bolt base and a spring are arranged in the outer casing, the slide block abuts on the chain to push the connection shaft leftwards by the pressure of the tension chain, and to make the spring in the compressing state by the compression of the fixed block and the connection shaft. Because the right end of the connection shaft and the transmission bar of the microswitch are closly contacted, the microswitch is in non compression state when the connection shaft moves leftwards, the microswitch is not in work state. Once the chain looses because of fault, the pressure to the slide block is reduced, the compressed spring is bounced, the connection shaft moves rightwards, the block at the left end of the connection shaft under the unction of the elastic force gradually compresses the transmission bar of the microswitch, thereby starting-up the microswitch, making the system alarming and automatically stopping the dynamic system for protecting.
Description
Technical field
The utility model relates to lifting weight safety guard technical field, relates in particular to a kind of disconnected loose chain checkout gear of chain damage that can prevent to hang.
Background technology
Raising along with developing of automobile industry and living standards of the people, city automobile occupancy volume per capita constantly increases, but increase along with urban population, people's living space is more and more littler, almost few of for the position of stopping, in order to adapt to the needs of parking, people begin to use in a large number multi-storied garage, to solve the problem of parking stall deficiency.In the multi-storied garage of having runed, no matter be planar movement class mechanical type three-dimensional garage or lifting cross sliding type mechanical stereo garage, use wire rope or chain to promote vehicle-containing mostly, because wire rope elasticity is bigger, reduce (bicycle parking) or increase (picking up the car) because of the load on the vehicle-containing during access vehicle, the wire rope of hanging vehicle-containing will shorten or extend, and amplitude can reach 20mm～30mm, cause vehicle-containing and ground to produce staggered floor, and have a strong impact on normal access vehicle.Therefore more be to use chain to promote vehicle-containing now; yet chain also can be owing to vehicle-containing constantly carries out upper and lower moving in use; cause chain wear or aging; cause chain loosening through regular meeting; and accidents caused generation; therefore topic between one of loose interchain topic is very serious though loose chain protective device occurred, is not all promoted the use of because of its complex structure poor reliability at present yet.
Summary of the invention
It is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, and is easy for installation and maintenance, and can guarantee the loose chain checkout gear of vehicle-containing safe operation.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of loose chain checkout gear comprises shell, microswitch, is connected with switch bracket and cover plate on the shell, is provided with stopping means in the shell, it is characterized in that: described microswitch is installed on the interior switch bracket of shell; Stopping means is made up of slide block, connecting axle, bolt block, spring, bolt block is fixed on the shell, slide block is articulated in the right-hand member end of the connecting axle that is stretched out by shell by bearing pin, slide block can slide between the carrier bar of both sides on the chain, the connecting axle right part can slide along shell, the left part of connecting axle is provided with block, block is close to the transmission levers of microswitch, can slide along the endoporus of bolt block in the middle part of connecting axle, the position that is positioned at the bolt block right part on the connecting axle is provided with fixed block, and described spring is between fixed block and bolt block.
Adjust for convenience, described block is threadedly connected on the connecting axle, and the diameter of block is increased to outside direction gradually by enclosure interior, and the corresponding position of cover plate and block is provided with through hole and can holds block and pass.
For safety and convenient the adjustment, microswitch described in the utility model adopts the little stroke travel switch of low-voltage, and the lead-out wire of microswitch is electrically connected with safety circuit.
The loose chain checkout gear that the utility model provides, slide block is close proximity on the chain, pressure when utilizing chain tightens, connecting axle is promoted left, extruding by fixed block and connecting axle makes spring be in compressive state, because the transmission levers of connecting axle right-hand member and microswitch closely contacts, microswitch was in no compressive state after connecting axle moved to left, and microswitch is not worked.In case chain is owing to fault relaxes; pressure to slide block reduces; compressed spring is upspring; connecting axle moves right; the block of connecting axle left end pushes the transmission levers of microswitch gradually under the effect of elastic force; thereby the startup microswitch makes system alarm and dynamical system is quit work automatically, plays a protective role.When the chain reparation, to the pressure recovery of slide block, connecting axle is still to left movement, and spring also is in compressive state, system's reinstatement attitude.
The beneficial effects of the utility model are:
1, loose chain checkout gear is rational in infrastructure, can open and close adjusting with the degree of tightness state of chain;
2, loose chain checkout gear is simple in structure, is easy to install and maintenance, and is safe and reliable.
3, loose chain checkout gear noise is little, highly sensitive, and braking ability is good, and is applied widely, highly versatile.
