Problems solved by technology

[0004] The existing elevator shafts generally do not have good protective measures. If the elevator door fails, the user may fall into the interior of the elevator shaft through the elevator door. If there are no protective measures, this will cause great harm to the user. Injury, which may lead to safety accidents in severe cases

Embodiment 1

[0037] Such as figure 1 and Figure 6 As shown, a protective device for an elevator shaft includes a hoistway main body 4, a hoist 11 is installed above the hoistway main body 4, a car 2 is installed inside the hoistway main body 4, and the top of the car 2 is fixedly connected with a rope 12;

[0038] A starting pole 7 is installed below the side of the car 2 close to the leveling sensor 9, and a protective mechanism 6 is installed at the intersection of the bottom of the starting pole 7 and the hoistway main body 4;

[0039] A transmission mechanism 5 is installed at the intersection of the protection mechanism 6 and the hoistway main body 4. The protection mechanism 6 is composed of a limit plate 61, a frame 62, a first pulley 63 and a protection net 64. The first pulley 63 is installed above the frame 62. The first pulley 63 is fixedly connected with the frame 62 by bolts, the protective net 64 is arranged inside the frame 62, the limit plate 61 is installed below the fra...

Embodiment 2

[0043] Such as image 3As shown, the transmission mechanism 5 is composed of a limit rod 51, a fixed plate 52, a cylinder assembly 53 and a transmission shaft 54. There is a sealing shaft, and the fixed disk 52 is installed on one end of the cylinder assembly 53. The fixed disk 52 is a disc-shaped structure. The side of the fixed disk 52 close to the cylinder assembly 53 is equipped with several screw rods and limit rods along the circumferential direction of the fixed disk 52. 51 is installed on the end of the transmission shaft 54 ​​close to the fixed plate 52, and the connection mode between the limit rod 51 and the transmission shaft 54 ​​is fixed by spot welding.

[0044] During specific use, when the transmission mechanism 5 is powered on, the cylinder assembly 53 drives the transmission shaft 54 ​​to move, so that the transmission shaft 54 ​​drives the limit rod 51 to move, so that the limit rod 51 can be separated from the limit disc 61, so that It is possible to make...

Embodiment 3

[0046] Such as Figure 7 As shown, the starting pole 7 is composed of a second pulley 71, a first connecting plate 72, a connecting piece 73, a first return spring 74, a fastener 75 and a cross bar 76, and the connecting piece 73 is installed on the first connecting plate 72. On one side, the first return spring 74 is installed under the first connecting plate 72, the cross bar 76 is installed under the first return spring 74, and the fastener 75 is installed at the intersection of the cross bar 76 and the first return spring 74 , the second pulley 71 is mounted on the end of the cross bar 76 away from the fastener 75 .

[0047] During specific use, when the first return spring 74 inside the start support rod 7 drives the start support rod 7 to rotate downward under the action of the car 2, the first return spring 74 accumulates energy, and when the car 2 and the start support rod 7 interact with each other When separating, when the first return spring 74 has no downward forc...

Abstract

The invention discloses a protection device for an elevator hoistway. The protection device for the elevator hoistway comprises a hoistway main body, an elevator is installed above the hoistway main body, a lift car is installed in the hoistway main body, the upper portion of the lift car is fixedly connected with a rope, and a starting supporting rod is installed below the side, close to a leveling sensor, of the lift car; and a protection mechanism is installed at the intersection of the lower portion of the starting supporting rod and the hoistway main body. The protection mechanism is installed on the lower side, close to an elevator door, in the elevator hoistway. A fixed seat and a transmission mechanism are mounted at the intersection of the protection mechanism and the hoistway main body. The transmission mechanism is electrically connected with the starting supporting rod; and in this way, the protection mechanism can be controlled to be opened and closed through the transmission mechanism, in this way, if a user falls off through the elevator door due to misoperating, the protection mechanism can play a bearing role under the action of the protection mechanism, and the user is prevented from falling to the position below the hoistway body.

Description

technical field [0001] The invention belongs to the technical field of elevator equipment, in particular to a protective device for an elevator shaft. Background technique [0002] The elevator shaft is the shaft where the elevator is installed. The size of the shaft is determined according to the selection of the elevator. The elevator track and the counterweight rail are installed on the shaft wall, and the elevator door is installed in the reserved door opening. There is an elevator machine room on the top of the shaft. [0003] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical lift has a car that runs between at least two vertical columns of...
