Abstract
The utility model discloses a guard for an escalator traction machine. The guard comprises a guard, a fixing support, a limit switch, a butterfly bolt and a hinge, wherein one end of the guard is fixedly connected onto the escalator traction machine, and the other end of the guard and the butterfly bolt are fixed by the fixing support; the limit switch is arranged on the guard, and the hinge is arranged between the butterfly bolt and the guard. The escalator traction machine provided by the utility model is safe and reliable; after the guard is opened by the butterfly bolt, an inertia wheel can be effectively stopped from rotating by a travel switch, and the operation is safer. The guard for the escalator traction machine is convenient to install and can be effectively removed.
Description
Technical field
The utility model relates to a kind of towing machine protective case, particularly a kind of arm rest lift traction machine protective case.
Background technology
China's staircase industry develop rapidly in recent years, the place that staircase is installed is increasing, and the safety problem of staircase has also more and more received social concern.With regard to arm rest lift traction machine, in order to obtain better performance, and increased inertia wheel device, but this device is also workman's installation simultaneously, maintenance has brought certain danger.
Generally adopt at present the mode that adds protective cover, isolate inertia wheel to reach the effect of protection, as shown below.There is dismounting trouble in this structure, the shortcoming of poor reliability, and also after protective cover is pulled down, inertia wheel still rotates, and has also strengthened danger.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of convenient disassembly, and only need turn on fly-headed bolt can open protective cover; Safe and reliable, when opening shielding type, limit switch action, the arm rest lift traction machine protective case that towing machine stops operating.
In order to achieve the above object; the utility model is by the following technical solutions: a kind of arm rest lift traction machine protective case; comprise protective cover, fixed support, limit switch, fly-headed bolt and hinge; one end of described protective cover is fixedly connected on arm rest lift traction machine; the other end of described protective cover is fixed by fixed support and fly-headed bolt; on described protective cover, limit switch is installed, between described fly-headed bolt and protective cover, is provided with hinge.
Adopt after technique scheme; the utlity model has following beneficial effect: arm rest lift traction machine protective case of the present utility model, safe and reliable, when opening after protective case with fly-headed bolt; can inertia wheel be stopped operating actv. by travel switch, operate safer.Arm rest lift traction machine protective case of the present utility model, easy for installation, can actv. dismounting.
Accompanying drawing explanation
Fig. 1 is front elevation of the present utility model.
Fig. 2 is back view of the present utility model.
In figure: 1, protective cover 2, fixed support 3, limit switch 4, fly-headed bolt 5, hinge.
The specific embodiment
According to Figure of description and specific embodiment, the utility model is further explained below.
As shown in Figure 1; a kind of arm rest lift traction machine protective case; comprise protective cover 1, fixed support 2, limit switch 3, fly-headed bolt 4 and hinge 5; one end of described protective cover 1 is fixedly connected on arm rest lift traction machine; the other end of described protective cover 1 is fixing by fixed support 2 and fly-headed bolt 4; on described protective cover 1, limit switch 3 is installed, between described fly-headed bolt 4 and protective cover 1, is provided with hinge 5.Now protective cover 1 is to be pressed on the bar of limit switch 3.In the time opening protective cover 1, only need turn on fly-headed bolt 4, raise protective cover 1 by hinge 5.Because protective cover 1 is opened, travel switch moves simultaneously, and inertia wheel also can stop operating thereupon.
