Description
Technical Field
The utility model relates to an elevator overhauls uses auxiliary device, especially a down prevention device of elevator.
Background
In order to ensure the normal use of the elevator, the elevator needs to be regularly checked and maintained. When overhauing the maintenance to the elevator pit, for the consideration of protection maintainer, prevent to overhaul the in-process elevator and fall suddenly, generally can place a maintenance in the maintenance pit of elevator and use down stop device. However, the existing descending device occupies a large volume and needs a deep pit, and the pit bottom depth of an elevator shaft of some low-rise buildings is usually small, so that the pit depth needs to be deepened, and the time and money are consumed. Moreover, the pressure-bearing strength of the existing stopping device is low. Therefore, the prior art has the problems of larger volume and lower pressure-bearing strength.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a down prevention device of elevator. The utility model has the characteristics of small in size and bearing strength are high.
The technical scheme of the utility model: the descending prevention device of the elevator comprises a fixed plate, wherein a bayonet is arranged at the upper end of the fixed plate, positioning plates matched with the bayonet are arranged on the back surface of the fixed plate, a stopping column is hinged between the two positioning plates, and a cushion pad is arranged above the end part of the stopping column; the front of fixed plate is equipped with two bases and the spacing seat in top that distribute from top to bottom, is equipped with two parallel distribution's guide bar between base and the spacing seat in top, is equipped with the slider between two guide bar, and it has the follow-up bracing piece to articulate on the slider, and follow-up bracing piece upper end is articulated with the bottom of backstop post.
In the descending prevention device of the elevator, the upper surface of the top limiting seat is provided with the magnet, the side end of the sliding block is hinged with the cover plate matched with the top limiting seat, and the inner bottom surface of the cover plate is provided with the magnetic block matched with the magnet.
In the descending prevention device of the elevator, the buffer pad comprises a bottom rubber pad and a top rubber pad, and a buffer spring group distributed in an annular shape is arranged between the bottom rubber pad and the top rubber pad.
Compared with the prior art, the utility model discloses constitute by fixed plate, bayonet socket, locating plate, articulated backstop post and cushion, it is installed on the lateral wall of well, rotates the backstop post to the position of use and can prevent the elevator to descend when needs use, simple structure, small in size, it is also convenient to operate. Simultaneously, support and fix the backstop post through the follow-up bracing piece, form a stable triangle-shaped structure between bracing piece, backstop post and the fixed plate, and then can effectual improvement bearing strength, guarantee the security of overhauing. Meanwhile, the limit of the base and the bottom limiting seat is realized, the cover plate is fixed with the magnet attracting block and the magnetic block in a matched mode, the stop column is not fixed through a pin shaft, and operation is simplified. To sum up, the utility model has the characteristics of small in size and bearing strength are high.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The descending prevention device of the elevator is shown in figures 1 to 3 and comprises a fixing plate 1, wherein a bayonet 2 is arranged at the upper end of the fixing plate 1, a positioning plate 3 matched with the bayonet 2 is arranged on the back surface of the fixing plate 1, a stopping column 4 is hinged between the two positioning plates 3, and a cushion pad 5 is arranged above the end part of the stopping column 4; the front of fixed plate 1 is equipped with two bases 6 and the spacing seat 7 in top that distribute from top to bottom, is equipped with two parallel distribution's guide bar 8 between base 6 and the spacing seat 7 in top, is equipped with slider 9 between two guide bar 8, and it has follow-up bracing piece 10 to articulate on the slider 9, and follow-up bracing piece 10 upper end is articulated with the bottom of backstop post 4.
The upper surface of the top limiting seat 7 is provided with a magnet 11, the side end of the sliding block 9 is hinged with a cover plate 12 matched with the top limiting seat 7, and the inner bottom surface of the cover plate 12 is provided with a magnetic block 13 matched with the magnet 11.
The cushion pad 5 comprises a bottom rubber pad 501 and a top rubber pad 502, and a buffer spring group 503 distributed annularly is arranged between the bottom rubber pad 501 and the top rubber pad 502.
The fixed plate can be installed on the shaft wall about 1.5 meters above the pit.
The utility model discloses a working process: mounting a fixed plate on the side wall of the well, and reserving the rotating distance of the stop post; or may be mounted on the back of the rail. When needs overhaul the pit, earlier through the rotatory apron of staff for apron and the spacing separation of seat in top, the subsequent decline of the slider of being convenient for, manual rotatory backstop post afterwards, make the backstop post rotatory around the hinge post, rotate the blotter of backstop post to the middle part of well, and the blotter is placed up, at the rotatory in-process of backstop post, the slider descends thereupon, and corresponding position is adjusted thereupon to the follow-up support column, moves to the bottommost end until the slider.
