Problems solved by technology

Analyzing this prior art scheme, it has the following technical defects: this prior art scheme is only suitable for the case where the floor door is a single door, and affected by the narrow space of the construction site, the site survey found that more than 70% of them can only be set as double doors. Therefore, its scope of use is greatly limited; the overall size is large, and the installation does not change.
[0004] In summary, the prior art mechanical landing door interlocking device has not been widely promoted and applied due to a series of technical defects

Embodiment 1

[0024] Such as figure 2 , image 3 As shown, an intercepting device includes a sleeve 1, the front end of the sleeve 1 is provided with a front cover 5 with a guide sleeve 6, the rear end of the sleeve 1 is provided with a rear end cover 2, and the sleeve 1 is equipped with There is a guide plug 4, the side of the guide plug 4 close to the front end cover 5 is connected with a connecting rod 9, and the outer end of the connecting rod 9 protrudes outside the guide sleeve 6, the guide plug 4 and the rear end cover 2 A compression spring 3 is installed between them, and a baffle plate 8 is installed at the outer end of the connecting rod 9 .

[0025] The baffle plate 8 adopts a square steel plate with a vertical side length of not less than 200mm and a thickness of not less than 5mm.

[0026] The cross section of the sleeve 1 is cylindrical.

[0027] The outer diameter of the sleeve 1 is consistent with the outer diameter of the construction frame pipe.

Embodiment 2

[0029] Such as Figure 4 , Figure 5 As shown, an intercepting device includes a sleeve 1, the front end of the sleeve 1 is provided with a front cover 5 with a guide sleeve 6, the rear end of the sleeve 1 is provided with a rear end cover 2, and the sleeve 1 is equipped with There is a guide plug 4, the guide plug 4 is connected with a stop rod 7 near the front end cover 5, and the outer end of the stop rod 7 protrudes outside the guide sleeve 6, the guide plug 4 and the rear end cover 2 Compression spring 3 is housed between. The cross section of the sleeve 1 is cylindrical. The outer diameter of the sleeve 1 is consistent with the outer diameter of the construction frame pipe.

Abstract

The invention discloses an interception device, belonging to the technical field of interlocking devices between construction hoists and floor protective doors. The interception device comprises a sleeve, wherein a front end cover provided with a guide sleeve is arranged at the front end of the sleeve, a back end cover is arranged at the back end of the sleeve, a guide plug is installed in the sleeve, one side, close to the front end cover, of the guide plug is connected with a connecting rod, the outer end of the connecting rod extends out of the guide sleeve, a compression spring is installed between the guide plug and the back end cover, and a baffle is installed at the outer end of the connecting rod. The invention has the advantages that the structure is simple, the installation is convenient, the reliability is good and the working condition adaptability is strong; and the interception device is particularly applicable to places with interlocking between the construction hoists and floor doors in building construction.

Description

technical field [0001] The invention relates to an intercepting device for intercepting travel switches correspondingly installed on the upper and lower sides of the construction elevator in the interlocking device between the construction elevator and the floor protective door. Background technique [0002] 5.2.15 of GB10055-2007 "Safety Regulations for Construction Lifts" stipulates that "the landing door should be electrically or mechanically interlocked with the cage. Only when the vertical distance between the bottom plate of the cage and a boarding platform is within ±0.25m, the platform's The landing door can be opened.", a large number of technical solutions have appeared in order to meet the mandatory regulations. However, the survey found that traditional technology is rarely used in actual implementation (in actual implementation, more than 80% of construction elevators are not equipped with interlocking devices for landing doors and cages). Analyzing the traditi...
