Abstract
The utility model discloses a chain breakage detection device. The chain breakage detection device comprises a shell, a baffle and a piston plate. A micro-switch is fixed in the shell and provided with a push rod in a matched mode, one end of the push rod contacts the micro-switch, the other end of the push rod penetrates through the baffle, the piston plate and the shell sequentially and extends out of the shell, the piston plate and the push rod are fixed together, springs are arranged between the baffle and the piston plate, the baffle is fixedly connected with the shell, and the push rod and the baffle can shift relatively in the axial direction. The chain breakage detection device has the advantages of being simple in structure, low in cost and suitable for detection of multiple chains, and falling of a car loading plate from a high altitude due to abrupt breakage of a dragging chain can be effectively prevented.
Description
Technical field
The utility model relates to chain detection apparatus, is specifically related to a kind of broken chain detecting device.
Background technology
Continuous development along with process of modernization, parking systems is dispersed throughout every field such as bustling business district of supporting, hotel, office of municipal government, residential quarter rapidly, is bringing into play important effect alleviating on a series of urban construction planning problems such as city parking difficulty, road be crowded parking systems.Meanwhile, people have also given great concern to some problems such as the security of operation of parking systems, urban environmental protection, standardized administrations, especially the security of operation in garage.The machinery garage at first will effectively guarantee the person and vehicle safety, but in lifting cross-sliding type, vertical circulation and simplified elevator tool multi-storied garage with chain lifting or balance, the situation of chain rupture, loose chain is difficult to detect, therefore, developing economic, safe, reliable, durable disconnected (pine) chain checkout gear has great importance.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of broken chain detecting device.
The technical solution of the utility model is: a kind of broken chain detecting device, comprise housing, baffle plate, piston plate, microswitch is also fixedly arranged in the described housing, described microswitch is adaptive a push rod, push rod one end contacts with described microswitch, the other end of described push rod passes baffle plate, piston plate and housing successively and stretches out housing, described piston plate and push rod are fixed together, be provided with spring between described baffle plate and the piston plate, described baffle plate is fixedlyed connected with housing, and described push rod and baffle plate can have axial relative displacement.
Further improvement of the utility model comprises:
The end that described push rod stretches out hull outside also is connected with slide block.
Described slide block is nylon slide block.
Described baffle plate is U-shaped baffle plate.
Described push rod is thread spindle.
Technique effect of the present utility model is: simple in structure, with low cost, can effectively prevent because of the unexpected fracture of conduction chain vehicle-containing to be fallen from the high-altitude.Be applicable to the detection of multiple chain.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the post-rift operating state schematic diagram of chain of the present utility model.
Among the figure: 1, housing, 2, piston plate, 3, spring, 4, thread spindle, 5, baffle plate, 6, nylon slide block, 7, microswitch.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, a kind of broken chain detecting device of the utility model, mainly by 1, housing 2, piston plate 3, spring 4, thread spindle 5, baffle plate 6, nylon slide block 7, microswitch etc. partly form, housing 1 is main body of the present utility model, be connected with the installation of garage body by it, be both the hole that thread spindle 4 passes baffle plate 5, with baffle plate 5 axial relatively moving can be arranged, separate with spring 3 between piston plate 2 and the baffle plate 5, baffle plate 5 is U-shaped, be connected with housing by bolt, thread spindle 4 can slide between housing 1 and baffle plate 5.Microswitch 7 is fixed on the housing 1, and this checkout gear mainly is installed in the chain middle part in lift-sliding parking system (or other promotes with chain or the multi-storied garage of balance), generally be contained in anti-jump carrier bar place.
The operating principle of this practical technique is: under normal working condition as shown in Figure 1, nylon slide block 6 is compacted, spring 3 between piston plate 2 and the baffle plate 5 is compressed, the thread spindle 4 that is connected with nylon slide block 6 also is crushed on the microswitch 7, microswitch 7 compacted closures, when loose chain or chain rupture situation appear in chain, chain fluffs as shown in Figure 2, since the elastic force of spring 3 with piston plate 2 to extrapolation, nylon slide block 6 and thread spindle 4 also outwards slide, at this moment thread spindle 4 separates with microswitch 7, and microswitch 7 disconnects, and device sends disconnected (pine) chain signal to the external world, the chain rupture situation appears in the prompting Hoisting System, when the operator receives signal, should look for the people to keep in repair immediately, avoid the generation of accident.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
