Detailed Description

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the present embodiment provides an elevator shaft operating platform which can be directly placed in an elevator shaft for use without being fixedly connected with a wall. Comprises an operation platform 100 and a plurality of brackets 200 vertically arranged below the operation platform. The support 200 is supported on the lower hoistway door opening for supporting the operation platform 100. The operation platform 100 is clamped at the junction of the upper layer and the lower layer in the elevator shaft and is used for a worker to stand on for construction operation.

The operation platform 100 comprises a square frame 101 and a steel plate 102 covering the square frame 101, and four lifting rings 103 are welded and fixed at four corners close to the steel plate and used for lifting the operation platform 100 by the crane. The square frame 100 is made according to the size of the cross section of the elevator shaft and may be equal to or slightly smaller than the size of the cross section of the elevator shaft. The square frame 101 may be formed by welding channel steel, and the steel plate 102 may be formed by welding a pattern steel plate having a thickness of 4mm on the upper surface of the square frame 101. In order to make the square frame 101 stronger, at least two cross beams 107 may be uniformly arranged in the square frame 101. In order to prevent the tools from falling down around the operation platform 100, the baffle 106 is arranged around the steel plate 102, and the height of the baffle 106 can be about 10 cm and lower than that of the hanging ring, and can be made of a steel plate. The hanging ring 103 can be made of round steel with the inner diameter of 15 cm.

This embodiment employs two brackets 200. Two brackets 200 are welded uniformly below the square frame 101, and the two brackets 200 are perpendicular to the square frame 101 and to the face of the elevator hoistway where the door opening is located. The bracket 200 comprises a vertical column 201, an inclined column 202 and a horizontal clamping rod 203 which are arranged on the same plane. The upper end of the upright column 201 and the upper end of the inclined column 202 are respectively welded and fixed below two opposite side frames of the square frame 101, the two side frames are parallel to the door opening, and the lower end of the inclined column 202 and one end of the horizontal clamping rod 203 are both welded and fixed at the lower part of the upright column 201. The welding position of the lower end of the inclined column 202 and the upright column 201 has a set distance from the lower end of the upright column 203, and a horizontal clamping rod 203 is welded on the opposite side of the welding position of the lower end of the upright column 201 and the inclined column 202.

The upright column 201 and the inclined column 202 form a right-angled triangle, the lower part of the upright column 201 and the horizontal clamping rod 203 form a right-angled leg, and the right-angled leg is clamped on the lower frame of the elevator shaft door opening. The distance between the horizontal stick 203 and the operation platform 100 is determined according to the floor height of a single elevator cage. A reinforcing rod 204 is welded between the upright 201 and the oblique column 202. Two connecting rods 205 are welded between the upright posts 201 of the two brackets 200, so that the brackets 200 are more stable, specifically, one connecting rod 205 can be welded in the middle of the upright post 201, and the other connecting rod 205 can be welded above the horizontal clamping rod 203 at the lower part of the upright post 201.

The bracket 200 may be formed by welding channel steel.

Due to the fact that the dimensions of the elevator shaft at each floor cannot be guaranteed to be exactly identical, appropriate deviations occur. In order to enable the operation platform to be clamped and fixed in the elevator shaft more horizontally, at least two bolt holes 104 are respectively arranged at the positions, close to two ends, of four side frames of the square frame 101. Bolt holes 104 are horizontally arranged in the frame, bolts 105 are screwed in the bolt holes 104, the bolts 105 can be M30 bolts, and head flanges of the bolts 105 face the outer side of the square frame 101 and are directed to the periphery of the elevator shaft. Preferably, the bolt hole 104 is a countersunk head, and the bolt 105 is a countersunk head hexagon socket head cap screw that fits into the bolt hole 104.

When the frame of square frame 101 can not be with fine the laminating of elevartor shaft inner wall, adjustable bolt 105's length of unscrewing, bolt 105's head flange and elevartor shaft inner wall contact have guaranteed that operating platform 10 better joint is in the elevartor shaft.

The use process comprises the following steps:

hook rings with the lifting machine, hang this elevartor shaft operation platform in the elevator shaft, block the right angle stabilizer blade that horizontal kelly 203 and stand 201 formed on the lower frame of lower floor's elevartor shaft door opening, operation platform 100 is located the bottom position of this layer of elevartor shaft. After the construction of this layer finishes, use the loop wheel machine to hook rings and promote this elevartor shaft operation platform to the upper story.
