Description

Slidingtype elevartor shaft protection system

Technical Field

The utility model belongs to the field of building construction, relates to a protection system, and particularly relates to a sliding type elevator shaft protection system.

Background

The construction field needs to protect the elevator shaft, and prevents constructors or articles from falling into the shaft to cause accidents. Traditional elevartor shaft protection is single reinforcing bar net piece or regularization protection network, fixes outside the elevartor shaft through expansion bolts. When entering the elevator shaft for construction, constructors can only twist off bolts around, and the protective net is detached to carry out construction operation. Because every time the elevator shaft enters or exits, the protective net needs to be dismantled, the workload is large, the problem of secondary fixation and infirm exists after the dismantling, and the safety of protection is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a sliding type elevator shaft protection system, which aims to solve the problem that in the prior art, a protective net needs to be integrally disassembled when an elevator shaft enters or exits.

The utility model provides a slidingtype elevartor shaft protection system, is including fixing attaching wall pole and guard gate in the elevartor shaft both sides, it is provided with the pulley track in the wall pole to attach, install first pulley on the pulley track, install the second pulley on the guard gate, the pulley track has U type cross-section in order to hold guard gate vertical motion in it.

Optionally, the first pulley is fixedly installed on the upper side of the pulley rail through a pin shaft, and the side surface of the protective door is in contact with the first pulley when the pulley rail moves.

Optionally, the second pulley is fixedly installed on the lower side of the protective door through a pin shaft, and the second pulley is in contact with the inner surface of the pulley rail when the pulley rail moves.

Preferably, the bottom of the protection door is provided with a buffer block.

Further, the buffer block is a rubber cushion block.

Optionally, the protective door body is made of steel wire mesh.

The elevator shaft protective door has the advantages that the elevator shaft protective door does not need to be repeatedly assembled and disassembled, the field construction work is reduced, and the protective safety is improved.

Detailed Description

Referring to fig. 1 and 2, a sliding type elevator shaft protection system includes a wall-attached rod and a protection door fixed at both sides of an elevator shaft, a pulley rail 1 is provided in the wall-attached rod, a first pulley 3 is installed on the pulley rail, a second pulley 4 is installed on the protection door 2, and the pulley rail has a U-shaped cross section to accommodate the vertical movement of the protection door therein. The first pulley 3 and the second pulley 4 change sliding friction between the protective door 2 and the pulley track 1 into rolling friction, and reduce the resistance of the up-and-down movement of the protective door. Because the pulley track has the U-shaped cross section, the edge of the protective door can be contained in the pulley track, and the protective door is prevented from being separated from the pulley track when moving up and down.

Referring to fig. 3, the first pulley 3 is fixedly installed on the upper side of the pulley rail 1 by a pin, and the side of the protection door 2 is in contact with the first pulley 3 when the pulley rail moves. Referring to fig. 4, the second pulley 4 is fixedly installed at the lower side of the protective door 2 by a pin, and the second pulley 4 is in contact with the inner surface of the pulley rail 2 when the pulley rail 1 moves. Install first pulley on fixed pulley track, second pulley is installed on the guard gate of activity, can make guard gate motion in-process system atress more even, avoids taking place unbalance loading and jamming problem.

With continued reference to fig. 4, the bottom of the protective door 2 is provided with a buffer block 5 to prevent the protective door 2 from colliding and damaging the ground when falling down. In particular, the buffer block is a rubber cushion block.

Optionally, the protective door body is made of steel wire mesh. On the one hand save material cost, on the other hand can alleviate guard gate weight owing to adopt hollow out construction, easy to assemble and use.

When a person or an article needs to enter the elevator shaft, the protective door 2 is pushed upward to be opened, as shown in fig. 2. When the person leaves the elevator shaft, the protective door 2 is closed, as shown in fig. 1. Even if the constructor forgets to close the door, the protection door 2 can also fall and close automatically under the action of gravity, so as to protect the elevator shaft.

The above-mentioned examples are only for describing the embodiment of the sliding elevator shaft protection system of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
