Abstract
The utility model discloses a loose and broken chain detection device which is characterized by comprising an approach switch arranged on a switch bracket, wherein the straight line where the approach switch is positioned is perpendicular to the plane where a lifting chain is positioned; the approach switch is positioned at the horizontal section of the lifting chain; and the approach switch is about 15 mm far from two end surfaces of the lifting chain. The approach switch is used for detecting the lifting chain and controlling a motor; and compared with the prior art, the detection device has the advantages of compact structure, low cost, safety and reliability.
Description
Technical field
The utility model relates to a kind of loose broken chain detecting device.
Background technology
At present; By new industry standard-required, multi-storied garage must be installed loose broken chain detecting device, and the loose broken chain detecting device that most of grounds chain promotes parking apparatus is to use microswitch or spring assembly; Using the shortcoming of microswitch is when chain rupture occurring; Chain is directly fallen on the switch, can form seriously switch to break, even can't use; Using the shortcoming of spring assembly is that spring lost efficacy easily, and processing, installs complicatedly, and cost is also high.
Summary of the invention
The purpose of the utility model be to provide a kind of overcome install shortcoming, compact conformation, low, the safe and reliable loose broken chain detecting device of cost in the past.
For achieving the above object, the technical scheme that the utility model adopted is following:
A kind of loose broken chain detecting device, comprise be installed on chain one side be used to detect chain near switch, saidly connect and the control motor near switch.
Above-mentioned checkout gear, it is said that straight line is vertical with plane, chain place towards the place near the switch detection; Saidly be positioned at chain near switch and locate for non-vertical section; Saidly be positioned at chain horizontal segment one side near switch.
Above-mentioned checkout gear, said is 10-20mm near switch and chain distance; Be preferably 15mm.
The operating principle and the beneficial effect of the utility model show:
To be arranged at chain one side near switch; And guarantee that itself and the horizontal range that promotes chain are about 15mm, detect near switch and promote chain, when loosening, sagging or chain rupture appear in chain; Chain is away near the position of the switch; Cause near switch and detect less than chain, send signal near switch, indication motor shuts down.
In the testing process, chain occurs when loosening or sagging, be in vertical section chain with even change near the variable in distance of switch is less, have coarse problem that detects; And the chain meeting nature under the effect of gravity that is in horizontal segment is sagging, makes to detect less than chain near switch, and accuracy of detection is higher relatively.
If near switch place straight line and plane, chain place out of plumb, there is certain angle in both, there is when having only the chain aeration level bigger the phenomenon that could detect and control the motor stall near switch, the detection inaccuracy; And when vertical with plane, chain place near switch place straight line and when being positioned at the horizontal segment of chain near switch, chain has slightly to become flexible and just can detect the accuracy of detection height.
It is thus clear that the utility model adopts and has replaced the prior art structure near switch, compares prior art; Can be so that the switch repeated use; When loose chain rupture situation occurring, can not cause to break and can in time control motor to make it stall, so need not change switch to switch; Reduced maintenance cost, more can the guarantor, the safety of car.
Description of drawings
Fig. 1 is the utility model master TV structure sketch map;
Fig. 2 is Fig. 1 vertical view;
Fig. 3 is Fig. 1 front view;
Wherein: 1. promote chain 2. switch brackets 3. near switch 4. equipment longerons.
The specific embodiment
Describe the present invention with the specific embodiment below:
Shown in Fig. 1-3, a kind of loose broken chain detecting device comprises near switch 3, saidly is installed on the switch bracket 2 near switch 3, and switch bracket 2 is installed on the equipment longeron 4.
Said near switch 3 place straight lines with to promote plane, chain 1 place vertical and be positioned at the horizontal segment that promotes chain 1 near switch 3, be about 15mm near switch 3 and lifting chain 1 two relative end face distances.
When lifting chain 1 becomes flexible; The sagging distance that horizontal segment promotes chain be directly proportional away from the sprocket wheel distance; It is big more promptly to promote the sagging distance of chain away from sprocket wheel more; Can confirm near the installation site of switch 3 and the distance of sprocket wheel based on accuracy of detection in view of the above, to adapt to the requirement of varying environment or other conditions.
During use, detect lifting chain 1 near switch 3, when promoting chain 1 operate as normal, both distances do not change, and do not send signal near switch 3, and motor runs well; When loosening, sagging or chain rupture appear in lifting chain 1, promote chain 1 away near switch 3 positions, cause near switch 3 and detect less than promoting chain 1, just send signal near switch 3, indication motor shuts down.
The utility model not only can be used for the parking apparatus of mechanical three-dimensional parking device or chain lifting on the ground, also can be used for the equipment that other need detect chain.
