Problems solved by technology

At the same time, it does not meet the provisions of 5.2.18 of GB10055-2007 "Safety Regulations for Construction Lifts" about "the installation position of the landing door locking device and its accessories should be set at a place where people are not easy to collide"
[0006] 3. In this prior art solution, since only one induction trigger device is provided, it can only realize the situation that the construction elevator is stopped at a certain floor and the door is not closed and the construction elevator is prohibited from starting.
[0007] 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

[0042] like figure 2 , image 3 As shown, an interlocking device for a construction hoist and a floor protection door includes travel switches XK1 and XK2 correspondingly installed on the top and bottom of the side of the construction hoist cage 1, and also includes stoppers corresponding to the upper and lower sides of the floor protection door 2. Plate type intercepting device 3; the guide plug 9 of the baffle type intercepting device 3 is connected to one end of the pull wire 12 on the side close to the rear end cover 8, and the other end of the pull wire 12 is connected to the door bolt 13 of the floor protection door 2. It should be noted that, in order to better illustrate the structure of the baffle-type intercepting device, figure 2 and image 3 The middle baffle is transparent.

[0043] like Figure 4 , Figure 5 As shown, the baffle type intercepting device 3 includes a sleeve 5, the front end of the sleeve 5 is provided with a front end cover 6 with a guide s...

Embodiment 2

[0047] like Image 6 , Figure 7 As shown, an interlocking device for a construction elevator and a floor protection door includes travel switches XK1 and XK2 corresponding to the top and bottom of the side surface of the construction elevator cage 1, and also includes corresponding to the upper and lower sides of the floor protection door 2. Barrier-type intercepting device 4; the guide plug 9 of the bar-type intercepting device 4 is connected to one end of a pull wire 12 on one side close to the rear end cover 8, and the other end of the pull wire 12 is connected to the door bolt 13 of the floor protection door 2. The pulling wire in this embodiment adopts the common bicycle brake wire.

[0048] like Figure 8 , Figure 9 As shown, the blocking bar type intercepting device 4 includes a sleeve 5, the front end of the sleeve 5 is provided with a front end cover 6 with a guide sleeve 7, and the rear end of the sleeve 5 is provided with a rear end cover 8, which The structur...

Abstract

The invention discloses an interlocking apparatus for a construction elevator and a floor protective door, which belongs to the technical field of the interlocking apparatus between the construction elevator and the floor protective door, and comprises travel switches and barrier blocking apparatuses, wherein the travel switches are correspondingly arranged on the top and the bottom of the side of a cage of the construction elevator, and the barrier blocking apparatuses are correspondingly arranged on the top and the bottom of the side of the floor protective door and connected to one end of a wire, the other end of the wire is connected with the latch of the floor protective door. The invention is simple in structure, is convenient to install, is highly reliabl, can be adapted to the working conditions, and is especially suitable for the interlocking between the construction elevator and the floor protective door in the building construction.

Description

technical field [0001] The invention relates to an interlocking device between a construction elevator and a floor protection 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 hanging cage. Only when the vertical distance between the bottom of the hanging cage and a boarding platform is within ±0.25m, the platform's The floor 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 hanging cages). Analyzing the traditional technology, the basic principle is to allow or prevent the lifting operation of the construction elevator by sensing and conduc...
