Description

Technical Field

[0001] The utility model relates to a shaft type elevator used for building construction, in particular to a hanging construction platform based on a self-climbing elevator machine room. Background Art

[0002] At construction sites, shaft-type construction elevators have been widely used. Existing shaft-type construction elevators are built and operated based on the shaft. The elevator car runs in the shaft and is protected by the shaft on all sides. At the same time, the counterweight-traction machine is used as the power, which fundamentally solves the risks of falling, hitting the top, and tipping. At the same time, it can also effectively avoid the various disadvantages brought by external construction elevators.

[0003] See also Figure 1 At present, there is a shaft type elevator, which includes a shaft 2 and an elevator room 1 arranged in the shaft 2. A traction machine 12 for traction of the car is arranged inside the elevator room 1, and an opening is arranged at the bottom of the elevator room 1. The traction machine 12 for traction of the car is lowered into the shaft 2 through the opening. A lock tongue retracting mechanism for climbing is arranged on the elevator machine room 1, including a shifting lock tongue retracting mechanism 13 and a positioning lock tongue retracting mechanism 14. The shifting lock tongue retracting mechanism 13 is arranged on the elevator machine room 1 based on a threaded rod lifting mechanism 15. In this way, the shifting lock tongue retracting mechanism 13 can be lifted and lowered relative to the positioning lock tongue retracting mechanism 14. A tongue hole 21 is arranged on the hoistway 2. The lock tongue extended by the shifting lock tongue retracting mechanism 13 or the positioning lock tongue retracting mechanism 14 can be inserted into the tongue hole 21 of the hoistway 2. When it is necessary to move the elevator machine room 1 in the hoistway 2 upward, first ensure that the lock tongue of the positioning lock tongue retracting mechanism 14 is in a state of being extended and inserted into the tongue hole 21, and then After that, the lock tongue of the shifting lock tongue retracting mechanism 13 is controlled to retract and disengage from the tongue hole 21, and then, the positioning lock tongue retracting mechanism 14 is controlled to descend relative to the elevator room 1, so that the elevator room 1 moves upward based on the shaft 2 until the shifting lock tongue retracting mechanism 13 corresponds to the tongue hole 21 in the upper row, and then, the lock tongue of the shifting lock tongue retracting mechanism 13 is controlled to extend and insert into the tongue hole 21, and then, the lock tongue of the positioning lock tongue retracting mechanism 14 is controlled to retract and disengage from the tongue hole 21, and then, the positioning lock tongue retracting mechanism 14 is controlled to rise relative to the elevator room 1, so that the positioning lock tongue retracting mechanism 14 corresponds to the tongue hole 21 in the upper row, and then, the lock tongue of the positioning lock tongue retracting mechanism 14 is controlled to extend and insert into the tongue hole 21. By repeating the above-mentioned action process continuously, the elevator machine room 1 can continuously climb until the elevator machine room 1 reaches the target position, the lock tongues of the shifting lock tongue retracting mechanism 13 and the positioning lock tongue retracting mechanism 14 are both extended and inserted into the tongue hole 21, and the elevator machine room 1 is positioned at the target position.

[0004] The current problem is:

[0005] When the elevator room 1 rises, the tongue holes 21 on the hoistway 2 below it are no longer needed. According to the requirements of the construction work, these tongue holes 21 should be filled and closed. However, there is currently no relevant operating platform to support operators to implement such operations. Summary of the invention

[0006] The utility model aims to provide a hanging construction platform based on a self-climbing elevator room, which can be used to fill the tongue hole that is no longer needed under the closed elevator room, thereby facilitating construction operations.

[0022] The utility model is further described below with specific embodiments:

[0023] This embodiment provides a hanging construction platform based on a self-climbing elevator room. The hanging construction platform is arranged based on the elevator room 1 mentioned in the background technology, and is arranged below the elevator room 1 .

[0024] Specifically, see Figure 2 ,

[0025] The hanging construction platform 3 includes a platform body 31 and four columns 32. The upper ends of the four columns 32 are fixedly connected to the bottom of the elevator room 1. The platform body 31 is fixedly connected to the lower ends of the four columns 32. The platform body 31 is fixedly arranged below the elevator room 1 through the four columns 32 and is in a hanging state.

[0026] The hanging construction platform 3 further includes a protective cage 33, which is in the shape of an upright cylinder. The protective cage 33 is vertically arranged in the middle of the hanging construction platform 3, and its position corresponds to the position where the traction machine 12 lowers the wire rope. The protective cage 33 is fixedly connected to the platform body 31 and the bottom of the elevator room 1, and the protective cage 33 penetrates the bottom of the elevator room 1 and the entire hanging construction platform 3. The wire rope lowered by the traction machine 12 in the elevator room 1 is in the protective cage 33, and the wire rope passes through the entire hanging construction platform 3 through the protective cage 33 to the elevator car below.

[0027] The function of the protective cage 33 is to surround the "wire rope lowered by the traction machine 12" and isolate the wire rope from the standing space of the hanging construction platform 3 to ensure that the workers on the hanging construction platform 3 will not have direct contact with the wire rope, thereby ensuring the safety of the workers.

[0028] A ladder 34 is provided between the platform body 31 and the elevator room 1 , so that the operators can conveniently go down from the elevator room 1 to the platform body 31 along the ladder 34 .

[0029] An anti-falling net 35 is provided below the platform body 31 , so as to prevent the operating personnel or operating tools from falling from the platform body 31 into the shaft 2 , thereby ensuring safe production.

[0030] An anti-top impact device 36 is provided below the platform body 31 to prevent the car from hitting the top when the elevator is running.

[0031] It should be noted that the anti-top impact device 36 is a device of the prior art, and its principle is: an angled steel plate is provided, and a buffer zone is provided between the uncontrolled upward car and the machine room to prevent the uncontrolled car from flying out due to inertia.

[0032] The function of the hanging construction platform in this embodiment is that after the elevator room 1 completes the upward climb, the operator can perform the construction work of filling and closing the tongue hole on the hanging construction platform 3. The details are as follows:

[0033] When the shaft 2 is raised, the elevator room 1 can climb upward along the raised shaft 2 until it reaches the top of the raised shaft 2. At this time, the tongue hole 21 that is no longer needed below the elevator room 1 needs to be filled and closed. The operator can climb down from the elevator room 1 along the ladder 34 to the lower hanging construction platform 3 below the elevator room 1, and fill and close the tongue hole 21 below the elevator room 1 on the lower hanging construction platform 3. After completing the operation, leave the lower hanging construction platform 3 via the ladder 34.

[0034] The innovative technical effects achieved by the hanging construction platform of this embodiment are as follows:

[0035] 1) A hanging construction platform is set up under the elevator room, which can be used to fill and close the tongue holes that are no longer needed, thus facilitating construction operations;

[0036] 2) A protective cage is used to surround the wire rope lowered by the traction machine, isolating the wire rope from the standing space of the hanging construction platform, thereby ensuring the safety of the operators;

[0037] 3) The anti-fall net and anti-top impact device installed under the platform body can prevent workers or work tools from falling from the platform body into the shaft, and prevent the elevator car from hitting the top when running, further ensuring safe production.
