Description

Technical Field

[0001] The invention relates to the technical field of wind pressure stabilizing devices, and in particular to a wind pressure buffering and stabilizing device for an elevator shaft. Background Art

[0002] The elevator shaft is the space where the car and counterweight device or hydraulic cylinder plunger move. This space is bounded by the bottom of the shaft pit, the shaft walls and the shaft top. The elevator shaft is a necessary space for the installation and use of the elevator. Therefore, during the installation and use of the elevator, there are strict requirements for the construction of the shaft.

[0003] Taking into account that the elevator will produce piston-like movement during its operation in the hoistway, which will lead to compression changes in the air pressure in the hoistway, and then increase the wind pressure in the hoistway. If this is not handled in time, the car will be affected by the high wind pressure in the hoistway, causing shaking and noise, making the passengers uncomfortable. Therefore, it is necessary to cooperate with the wind pressure stabilizing device to stabilize the wind pressure. Therefore, some wind pressure stabilizing devices with special structures and functions can be used.

[0004] Generally, when using traditional wind pressure stabilization devices, they often take the approach of setting up multiple pressure relief vents for pressure relief. The pressure relief vents have a simple structure, and during the pressure relief process, when the wind pressure is relieved from the outlet, the pressure inside the car will increase, and the wind pressure cannot be transferred. In addition, during the pressure relief process at the outlet, the car is still used as a pressure relief channel, which causes the car to still vibrate during pressure relief. When the pressure is released, people riding in the car will feel uncomfortable, and the strong wind pressure will still produce a large impact pressure on the car and the air duct, thereby aggravating the shaking of the car and the shaft, which is very inconvenient.

[0005] In summary, it is necessary to propose an elevator shaft wind pressure buffering and stabilizing device to solve the above problems. Summary of the invention

[0069] The overall working principle of the above is:

[0070] When in use, the first rectangular ring clamp frame 210 is clamped with the top inner wall of the well frame 1, and the threaded clamp rod 221 and the threaded clamp cylinder 222 are auxiliary fixed. At this time, the wind pressure inside the well frame 1 can drive the first sliding rod 25 to slide on the inner wall of the first fixed cylinder 24, and then drive the first spring 29 to deform, so that the first blocking block 28 cooperates with the first pressure relief circular groove 23 to relieve pressure;

[0071] At the same time, when the car moves upward, the second sliding rod 215 can be driven to slide on the inner wall of the second fixed cylinder 214, so that the second spring 218 can be deformed, and the second blocking block 217 can be driven to move, and the second pressure relief groove 220 can be used to assist in pressure relief;

[0072] When conduction pressure relief is required, the first rectangular ring block 36 is clamped with the first rectangular ring frame 32, and the threaded clamping rod 35 is threadedly clamped with the first threaded hole 34, and then the second threaded hole 37 can be used for auxiliary fixation.

[0073] At this time, when pressure relief is required, the first pressure relief rectangular groove 219 and the second pressure relief rectangular groove 31 can cooperate to transmit the wind pressure to the first wind guide rectangular frame 38 and the second wind guide rectangular frame 39, which can drive the rectangular slider 322 to slide on the outer surface of the fixed round rod 321, and then drive the third spring 323 to deform, so as to perform auxiliary pressure relief. At the same time, when the rectangular slider 322 moves to a suitable position, the third wind guide rectangular frame 310 can be exposed, and then the wind pressure can be introduced into the interior of the well frame 1 to form a closed loop, thereby avoiding the wind pressure reduction caused by the movement of the car at the bottom or top, which is used to balance the wind pressure;

[0074] When emergency pressure relief is required, the threaded rod 43 is rotated to move the connecting auxiliary plate 45, which can drive the third blocking block 410 and other components to move. At this time, the wind pressure can drive the third blocking block 410 to move, and then drive the sliding cylinder 48 to slide on the outer surface of the fixed rod 47, and then drive the fourth spring 49 to move, so as to perform auxiliary pressure relief buffering.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
