Abstract
The utility model discloses a protector for a loose chain and a broken chain. The protector for the loose chain and the broken chain comprises a shell, wherein two swing pieces are arranged in the shell, the upper portions of the swing pieces are connected with the shell in a hinged mode, and the lower portion of each swing piece is provided with a friction block. Two springs are arranged in the shell, one end of each spring is connected with the shell, and the other end of each spring is connected with one of the friction blocks. An adjusting bolt is arranged on each swing piece, two micro active switches are arranged in the shell, and a contact piece is arranged on each micro active switch. According to the technical scheme of the protector for the loose chain and the broken chain, once a chain is loose or broken, the swing pieces pop out under the action of the springs, and the adjusting bolts on the swing pieces move away from the contact pieces on the micro active switches, so the micro active switches obtain alarming signals, and the alarming signals are transferred to a control system. As a result, a power supply of a machine can be shut off in time to enable the machine to stop operating, and a danger can not worsen. The protector for the loose chain or the broken chain has the advantages of being simple in structure, wide in application, strong in reliability, good in hidden property, low in cost and the like.
Description
Technical field
The utility model belongs to safeguard, relates in particular to a kind of protector that carries out power alarm can in chain elevating movement process, loose chain or crack conditions occur the time.
Background technology
Along with progressively popularizing of automobile; Parking difficulty highlights day by day, and the stereo parking facility that arises at the historic moment is also progressively accepted by masses, like the stereo parking facility of lifting cross sliding type; Be employing chain or wire rope lifting medium mostly as vehicle-containing; After promoting and to put in place, vehicle-containing can protect the safety of vehicle when chain or wire rope rupture suddenly by the catching device of top, if but in lifting process, rupture suddenly, then there is not effective safety precautions.
Summary of the invention
Thereby providing, the purpose of the utility model a kind ofly contacts to earth and the moment of the loose chain that causes is carried out the protector that power alarm makes that equipment is out of service in fracture or at vehicle-containing when chain.
For realizing above-mentioned purpose, the utility model adopts following technical scheme: a kind of loose chain, break chain protector comprise housing; Two goods of furniture for display rather than for uses are arranged in the housing, and the top and the housing of goods of furniture for display rather than for use are hinged, and brake pad is equipped with in the bottom of each goods of furniture for display rather than for use; Two springs are arranged in the housing, and an end and the housing of each spring join, and the other end of spring and a brake pad join; An adjustment bolt is housed on each goods of furniture for display rather than for use, two microswitches also are housed in the housing, contact is all arranged on each microswitch.
Two cappings also are housed on the housing.
Cable cover(ing) is housed on the housing, and cable passes cable cover(ing) and links to each other with microswitch.
Adopt loose chain, the break chain protector of technique scheme, in case chain fracture or loose chain situation take place, goods of furniture for display rather than for use can outwards eject under the effect of spring; Adjustment bolt on the goods of furniture for display rather than for use will break away from the contact on the microswitch; Thereby make microswitch obtain alarm signal, send the control system to, can in time cut off the power supply of equipment; Make equipment out of service, make danger further not worsen.The utlity model has simple in structure, be widely used, characteristics such as good reliability, good concealment, cost are low.
Description of drawings
Fig. 1 is the exploded perspective view of the utility model structure.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Like Fig. 1, a kind of loose chain, break chain protector shown in Figure 2, comprise housing 1, two goods of furniture for display rather than for uses 9 are arranged in the housing 1; Axis hole is arranged at the top of goods of furniture for display rather than for use 9, and hinged with spring I 8 and housing through bearing pin 7, brake pad 13 is equipped with by hold-down nut 12, lock bolt 14 in the bottom of each goods of furniture for display rather than for use 9; Two spring II 15 are arranged in the housing; One end and the housing of each spring II 15 join, and the other end of spring II 15 and a brake pad 13 join, and an adjustment bolt 10 is housed on each goods of furniture for display rather than for use 9; Also two microswitches 5 are housed in the housing 1, on each microswitch 5 contact are arranged all through bolt 4, nut 6.Cable cover(ing) 2 is housed on the housing, and cable 3 passes cable cover(ing) 2 and links to each other with microswitch 5.Two cappings 11 also are housed on the housing.
The operating principle of the utility model is following: the lifting chain of both sides or wire rope compressing brake pad 13 make goods of furniture for display rather than for use 9 inwardly receive round bearing pin 7; Adjust bolt 10 this moment and can oppress the contact on the microswitch 5; Make microswitch 5 obtain or loss signal; In case promote chain or wire rope ruptures or vehicle-containing contacts to earth makes and promote chain or wire rope loosens that goods of furniture for display rather than for use 9 will outwards eject under the effect of spring II 15 together with brake pad 13, adjust bolt 10 and will stop the compressing to contact on the microswitch 5; Make microswitch 5 lose or obtain signal, make equipment out of service thereby feed back to the control system.
