Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to elevators, especially a helipad elevator. Background Technology

[0002] A rooftop helipad is a facility located on the roof of a building for helicopter takeoff, landing, and parking. It is primarily used in urban disaster prevention and mitigation command and dispatch centers, important medical treatment centers, and high-rise buildings. To facilitate helicopter takeoff and landing, the rooftop needs to be a flat platform without any protruding buildings or structures, allowing for the transport of personnel and goods to meet accessibility requirements. Therefore, in existing technology, a top cover is installed at the top of the elevator shaft, flush with the roof surface. During use, the top cover and the elevator car rise together above the roof surface. However, existing systems use independent drive units for the top cover and the elevator car; the top cover is driven by a separate drive unit, while the elevator car relies on a separate lifting system. This design results in complex equipment structures, high costs, and large space requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a helipad elevator to solve the technical problems of complex structure, high cost and large space occupation of existing helipad elevator equipment.

[0004] This utility model provides a helipad elevator, including a shaft, a car frame installed in the shaft, guide rails installed at the four corners of the shaft along the vertical direction, a car installed in the car frame, and at least two guide shoes spaced at each of the four corners of the car frame along the vertical direction. The guide shoes cooperate with the guide rails. A hydraulic cylinder is fixedly installed at the bottom of the shaft, and the piston rod of the hydraulic cylinder is connected to the bottom of the car frame. A top cover plate is installed at the top of the shaft, and guide rods are fixedly connected at the four bottom corners of the top cover plate. The guide rods extend downward into the shaft and form a vertical sliding pair with the side wall of the shaft. A flexible buffer structure that cooperates with the top cover plate is installed at the top of the car frame.

[0005] Furthermore, the guide shoes are located at the lower part of the car, and roller guide shoes are respectively provided on the right rear side and left front side of the top of the car. Guide rail sections that cooperate with the roller guide shoes are respectively fixed on the right rear side and left front side of the bottom of the top cover plate, and the guide rail sections are connected to the guide rails on the right rear side and left front side of the hoistway.

[0006] Furthermore, the guide rail is installed on the side wall of the shaft via a guide rail bracket.

[0007] Compared with existing technologies, the advantages of this invention are positive and significant. This invention uses a hydraulic cylinder to lift the car frame, which directly lifts the top cover plate, eliminating the need for a separate drive unit. This simplifies the structure, reduces the space occupied by the equipment, and lowers costs. Attached Figure Description

[0014] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0015] like Figures 1-6 As shown, this utility model provides a helipad elevator, including a shaft, a car frame 1 installed in the shaft, guide rails 2 installed at the four corners of the shaft along the vertical direction, a car installed in the car frame 1, and at least two guide shoes 3 installed at each of the four corners of the car frame 1 along the vertical direction at intervals. The guide shoes 3 cooperate with the guide rails 2. A hydraulic cylinder 4 is fixedly installed at the bottom of the shaft, and the piston rod of the hydraulic cylinder 4 is connected to the bottom of the car frame 1. A top cover plate 5 is installed at the top of the shaft, and guide rods 10 are fixedly connected at the four bottom corners of the top cover plate 5. The guide rods 10 extend downward into the shaft and form a vertical sliding pair with the side wall of the shaft. A flexible buffer structure 6 is installed at the top of the car frame 1 to cooperate with the top cover plate 5.

[0016] Working principle:

[0017] When the elevator car needs to reach the helipad floor, the hydraulic cylinder 4 drives the elevator car frame 1 to lift. The flexible buffer device on the elevator car frame 1 contacts the top cover plate 5 for cushioning. As the elevator car frame 1 rises, the top cover plate 5 is lifted upwards. The rising and falling process of the top cover plate 5 is guided by the guide rod 10. After the elevator car frame 1 reaches the designated position, the landing door opens, and personnel enter and exit through the landing door. Figure 1 As shown, the top-floor door opens to the right. Figure 2 As shown, the bottom floor door opens to the front.

[0018] This utility model uses a hydraulic cylinder 4 to lift the car frame 1, and the car frame 1 directly lifts the top cover plate 5. There is no need to equip the top cover plate 5 with an independent drive device, thereby simplifying the structure, reducing the space occupied by the equipment, and reducing the cost.

[0019] Furthermore, the guide shoe 3 is located at the lower part of the car, and roller guide shoes 7 are respectively provided on the right rear side and left front side of the top of the car. Guide rail sections 8 that cooperate with the roller guide shoes 7 are respectively fixed on the right rear side and left front side of the bottom of the top cover plate 5. The guide rail sections 8 connect to the guide rails 2 on the right rear side and left front side of the hoistway. When the car arrives at the landing floor, the rolling guide shoe 3 on the car frame 1 enters the guide rail section 8 at the bottom of the top cover plate 5. The guide rail section 8 on the top cover plate 5 plays a limiting role for the rolling guide shoe 3. The guide rod 10 is used to guide and limit the top cover plate 5, making the car frame 1 more stable when it arrives at the landing floor.

[0020] Furthermore, the guide rail 2 is installed on the side wall of the well shaft via the guide rail bracket 9.

[0021] Specifically, the specific structure and principle of the car frame 1, guide rail 2, car, guide shoe 3, hydraulic cylinder 4, flexible buffer structure 6, roller guide shoe 7 in this utility model, as well as other aspects not described in detail, all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here.
