Abstract
The utility model discloses car top guard device in a kind of elevator.Comprise two vertical fixedly straight tubes, described fixedly between straight tube level be fixedly connected with toeguard and fixing transverse slat, and be equipped with central shaft hole, in central shaft hole, be vertically provided with movable straight tube, movable straight tube with fixedly between straight tube, by necking down ring, be fixedly connected with jam nut, fixedly straight tube is provided with mechanical collision switch, the open contact of mechanical collision switch is incorporated to overhauling elevator loop, normally closed contact access sedan-chair top board entrance point, the movable transverse tube of level connection joint between movable straight tube, movable transverse tube is provided with the collision arm for collision machine impact switch.Its beneficial effect is: guardrail liftable in this device, and the switch be incorporated to maintenance loop is set, solved the too small problem of elevator hoistways overhead, and car is forbidden operation at non-inspecting state while guaranteeing that guardrail rises, and has improved elevator safety performance.
Description
Technical field
The utility model belongs to lift facility field, relates in particular to car top guard device.
Background technology
Elevator becomes more and more popular now, and its share of market is also increasing, and builder is in order to practice every conceivable frugality space, causes its integral layout all quite compact, and this arrangement can cause elevator top space too small.Sedan-chair top guard rail plays protection and the effect of protecting to the person and equipment; it is a kind of very important safety protection facility; but current sedan-chair top guard rail height is fixed; larger to hoistway overhead demand; this exerts an influence to the design of car top guard, installation, highly probably can not meet GB requirement.
Utility model content
In order to address the above problem, the utility model provides a kind of liftable and with car top guard device in the elevator of switch.
According to an aspect of the present utility model, provide car top guard device in a kind of elevator.Comprise two vertical fixedly straight tubes, described fixedly between straight tube level be fixedly connected with toeguard and fixing transverse slat, fixedly straight tube is equipped with central shaft hole, in central shaft hole, be vertically provided with movable straight tube, movable straight tube with fixedly between straight tube the object by adjustable straight tube height be connected, fixedly straight tube is provided with mechanical collision switch, the movable transverse tube of level connection joint between moving straight tube, and movable transverse tube is provided with the collision arm for collision machine impact switch.Its beneficial effect is: guardrail liftable in this device, and the switch be incorporated to maintenance loop is set, solved the too small problem of elevator hoistways overhead, and car is forbidden operation at non-inspecting state while guaranteeing that guardrail rises, and has improved elevator safety performance.
In some embodiments, described movable straight tube is fixedly connected with jam nut by necking down ring with fixing straight tube, and its beneficial effect is: the height of conveniently adjusted movable straight tube, meets the requirement of GB guardrail.
In some embodiments, the open contact of described mechanical collision switch is incorporated to overhauling elevator loop, normally closed contact access sedan-chair top board entrance point, and its beneficial effect is: when movable straight tube shrinks or rise, guaranteed elevator operation, improved elevator safety performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model contraction state.
Fig. 2 is the structural representation that the utility model rises state.
Fig. 3 is the fixedly connection diagram of straight tube and movable straight tube of the utility model.
In figure: 1, fixing straight tube, 2, toeguard, 3, fixing transverse slat, 4, movable straight tube, 5, necking down ring, 6, jam nut, 7, movable transverse tube, 8, collision arm, 9, mechanical collision switch.
The specific embodiment
Below in conjunction with 1 to 3 pair of the utility model of accompanying drawing, be further described.Fig. 1 to 3 schematically shows car top guard device in the utility model elevator, comprise two vertical fixedly straight tubes 1, described fixedly between straight tube level be fixedly connected with toeguard 2 and fixing transverse slat 3, fixedly straight tube is equipped with central shaft hole, in central shaft hole, be vertically provided with movable straight tube 4, movable straight tube with fixedly between straight tube, by necking down ring 5, be fixedly connected with jam nut 6, fixedly straight tube is provided with mechanical collision switch 9, the open contact of described mechanical collision switch 9 is incorporated to overhauling elevator loop, normally closed contact access sedan-chair top board entrance point.The movable transverse tube 7 of level connection joint between movable straight tube 4, movable transverse tube 7 is provided with the collision arm 8 for collision machine impact switch 9.Movable straight tube 4, when contraction state, compresses mechanical impact switch 9, and car can normally move, overhaul; Movable straight tube 4 when rising state, release mechanism impact switch 9, car can only be forbidden normal operation at inspecting state, avoids movable straight tube 4 to rush to summit, and has guaranteed the safety performance of elevator.
Above-described is only embodiments more of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of creation design of the present utility model; can also make other distortion and improvement, these all belong to protection domain of the present utility model.
