Abstract
The invention provides elevator car roof safe protective guards which comprise a left protective guard, a right protective guard, a front protective guard and a rear protective guard. The front protective guard is composed of a fixed protective guard body and a movable protective guard body. The movable protective guard body is movably connected with the left protective guard. The fixed protective guard body is fixedly connected with the right protective guard. The fixed protective guard body is connected with the movable protective guard body through latch locks. A support touch plate is mounted on the movable protective guard body. A safe switch is mounted on the fixed protective guard body. In a normal state, the movable protective guard body is in a closed state, the support touch plate makes contact with the safe switch, and an elevator runs normally. When maintenance is carried out, the movable protective guard body is opened, the safe switch is switched off, a car roof overhaul switch is then pressed down, the elevator stops working, the movable protective guard body is then closed, and the protective guards are arranged on the periphery of a car roof. The elevator car roof safe protective guards have the advantages that the area of safety protection of the car roof is enlarged, the intensity of the protective guards can be improved, and the elevator car roof safe protective guards are high in safety factor, simple in structure and convenient to mount.
Description
Technical field
The invention belongs to elevator reparing protection field, especially relate to a kind of elevator car top safety guide rail.
Background technology
Fall when the effect of guard rail mainly prevents maintainer from overhauling hoistway accidentally; play safety guard-safeguard effect; and guard rail great majority in traditional sedan-chair top adopt three fence designs; usually three the guard rail frameworks become by direct square tubes soldering form; and then fix with upper beam on sedan-chair top, can not well ensure maintainer's safety.
Summary of the invention
The problem to be solved in the present invention is to provide the high guard rail design of a kind of safety factor, particularly relates to a kind of elevator car top safety guide rail.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of elevator car top safety guide rail, comprise left side guard rail, right side guard rail, front guard rail and rear protective guard, described rear protective guard is connected with described left side guard rail and described right side guard rail respectively, described front guard rail is made up of nonfloating rail and movable rail, described movable rail is flexibly connected with left side guard rail, described nonfloating rail is fixedly connected with right side guard rail, described nonfloating rail is connected with described movable rail, the frame bottom that described nonfloating rail contacts with described movable rail is provided with safety switch, middle part is provided with baffle plate, the frame of described movable rail is provided with support touch panel with described safety switch corresponding section, under normal condition, movable rail is in closed condition, now support touch panel contacts with safety switch, safety switch closes, elevator normally runs, when it is time for repair, maintainer opens movable rail, and elevator quits work, and presses cage top overhauling switch after entering sedan-chair top, closes movable rail, makes sedan-chair top surrounding have guardrail, makes the safety of maintainer more secure.
Further, described rear protective guard is consistent with described front guardrail structure, as another kind of assembling scheme of the present invention.
Further, described movable rail and left side guard rail, by gemel connection, make movable rail can free-open-close, and described nonfloating rail welds with right side guard rail or is connected with bolt.
Further, the frame upper end that described movable rail contacts with described nonfloating rail is provided with pin lock, described movable rail is connected by described pin lock with described nonfloating rail, movable rail close rear formed four sides around guard rail, improve the safety factor of guard rail.
The advantage that the present invention has and good effect are: the area that not only can increase elevator car top safety precaution, can also improve the intensity of guard rail, have safety factor high, and structure is simple, advantage easy for installation.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in figs. 1 and 3, a kind of elevator car top safety guide rail, comprise left side guard rail 1, right side guard rail 2, front guard rail 4 and rear protective guard 3, described left side guard rail 1 is connected with type elevator car frame upper beam respectively with described right side guard rail 2, described rear protective guard 3 is connected with described left side guard rail 1 and described right side guard rail 2 respectively, described front guard rail 4 is made up of nonfloating rail 5 and movable rail 6, described movable rail 6 is flexibly connected by hinge 11 with left side guard rail 1, make movable rail 5 can free-open-close, described nonfloating rail 6 welds with right side guard rail 2 or bolt is fixedly connected with, described nonfloating rail 6 and described movable rail 5 are locked by pin lock 7 or wagon box and are connected, the frame bottom that described nonfloating rail 6 contacts with described movable rail 5 is provided with safety switch 9, middle part is provided with baffle plate 8, the frame of described movable rail 5 is provided with support touch panel 10 with described safety switch 9 corresponding section, under normal condition, movable rail 5 is in closed condition, now support touch panel 10 contacts with safety switch 9, safety switch 9 closes, elevator normally runs, when it is time for repair, maintainer opens movable rail 5, and safety switch 9 disconnects, and elevator quits work, and presses cage top overhauling switch after entering sedan-chair top, then closes movable rail 5, makes sedan-chair top surrounding have guardrail.
As shown in Figures 2 and 3, another kind of assembling scheme of the present invention is: described rear protective guard 3 is consistent with described front guard rail 4 structure, and other structures are consistent with Fig. 1 assembling scheme.
The working process of this example: when elevator normally runs, movable rail 5 and nonfloating rail 6 are locked by pin lock 7 or wagon box and are connected, movable rail 5 is in closure state, support touch panel 10 on movable rail 5 contacts with the safety switch 9 on nonfloating rail 6, safety switch 9 closes, and elevator normally runs; When needs overhaul; maintainer opens movable rail 5; then support touch panel 10 and safety switch 9 disconnect; elevator can not normally run, and after maintainer enters sedan-chair top, presses cage top overhauling switch in time; elevator is in dormant state; and then close movable rail 5, make sedan-chair top surrounding have guardrail to protect, thus make maintainer safer.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
