Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and in particular to a flow deflector for a high-speed elevator. Background Art

[0002] When the operating speed of the elevator exceeds 4m / s - 6m / s, the high-speed flow of air will be caused around the elevator car running in the narrow hoistway. When the air flows at high speed past the traditional square car, aerodynamic resistance and aerodynamic noise will be generated, and the high-speed impact of the air will also cause the vibration of the car.

[0003] As disclosed in the authorized announcement number CN209702066U, a flow deflector for a high-speed elevator includes a housing and a support frame arranged inside the housing. The housing includes a front panel, a rear panel, a left side panel and a right side panel. The front panel is an upright plate with a curved top edge, and the rear panel, the left side panel and the right side panel are curved panels. The left side panel and the right side panel respectively intersect with the top edge of the front panel. However, although this flow deflector saves the top floor space, after the elevator has been used for a period of time, the hoistway components and guide rails need to be maintained. This requires the removal of the flow deflector, which is time-consuming and laborious, and it is not easy to reinstall it after the maintenance, having great limitations. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a flow deflector for a high-speed elevator.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] A flow deflector for a high-speed elevator includes a framework and vertical plates arranged around it. The top end of the vertical plate is pivotally provided with a flip plate that can be turned over. Above the flip plate, there is a cover plate that can move up and down relative to it. The cover plate can be locked on the flip plate under the drive of a locking component. The vertical plate, the flip plate and the cover plate cooperate with each other to form a relatively sealed cavity. The flip plate includes an integrally formed vertical end and an inclined end. The vertical end is pivotally connected to the vertical plate, and the inclined end can be locked with the cover plate. The angle between the vertical end and the inclined end is an obtuse angle, and its angle is between 120 - 150°.

[0007] Preferably, a hinge is fixed on the flip plate, and the other side of the hinge is fixed on the vertical plate.

[0008] Preferably, a limiting member is fixed on the vertical plate. The limiting member is semi-circular. One end of it is fixed on the vertical plate, and the other end can abut against the upper surface of the flip plate.

[0009] Preferably, a shock-absorbing pad is attached to the end of the limiting member close to the flip plate.

[0010] Preferably, reinforcing ribs are fixedly arranged on the inner wall of the flap.

[0011] Preferably, the locking assembly at least includes a base fixedly arranged on the cover plate. Accommodating holes are formed on both sides of the base. An accommodating block is pivotally arranged in the accommodating hole. A claw is fixedly arranged on the accommodating block. A tongue is arranged on the flap. The claw can be clamped into the clamping groove of the tongue to lock it.

[0012] Preferably, a pull plate is also pivotally arranged on one side of the accommodating block away from the claw.

[0013] The beneficial effects of the present utility model are mainly reflected in:

[0014] 1. Exquisite design. When it is necessary to maintain and service the shaft components and guide rails, the cover plate can be removed, and then the shaft components and guide rails can be quickly maintained and serviced. The operation is simple, convenient, stable and reliable, greatly improving work efficiency, reducing work intensity, and having wide applicability;

[0015] 2. The V-shaped design of the flap enables air to smoothly flow along the streamline of the curved panel of the housing when the elevator is running at high speed, making the movement of air flowing over the top of the elevator car become gentle, reducing phenomena such as air resistance, aerodynamic noise and turbulence, and improving the comfort and safety of passengers when taking a high-speed elevator;

[0016] 3. The setting of the limiting member can limit the flipping angle of the flap. At the same time, it is also convenient to reset it after maintenance, which can improve convenience;

[0017] 4. Pulling the pull plate can drive the claw to move forward through the accommodating block until the claw is clamped with the tongue. The operation is simple and convenient, facilitating disassembly, replacement and maintenance, and greatly improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical end 31 is pivotally connected to the vertical plate 2, and the inclined end 32 can be locked with the cover plate 4. The angle between the vertical end 31 and the inclined end 32 is an obtuse angle, and its angle is between 120° and 150°. The V-shaped design of the flip plate 3 enables air to smoothly flow along the streamline of the curved panel of the housing when the elevator is running at high speed, making the movement of the air flowing over the top of the elevator car gentle, reducing phenomena such as air resistance, aerodynamic noise, and turbulence, and improving the comfort and safety of passengers when taking a high-speed elevator.

[0028] Above the flip plate 3, there is a cover plate 4 that can move up and down relative to it. The cover plate 4 can be locked on the flip plate 3 under the drive of a locking assembly 5. The vertical plate 2, the flip plate 3, and the cover plate 4 cooperate with each other to form a relatively sealed cavity. When it is necessary to maintain and service the hoistway components and guide rails, removing the cover plate 4 can quickly perform maintenance and servicing on the hoistway components and guide rails. The operation is simple, convenient, stable, and reliable, greatly improving work efficiency, reducing work intensity, and having wide applicability.

[0029] A hinge 33 is fixedly installed on the flip plate 3, and the other side of the hinge 33 is fixedly installed on the vertical plate 2. A limiting member 21 is fixedly installed on the vertical plate 2. The limiting member 21 is semi-circular. One end of it is fixedly installed on the vertical plate 2, and the other end can abut against the upper surface of the flip plate 3. The setting of the limiting member 21 can limit the flipping angle of the flip plate 3. At the same time, it is also convenient to reset it after maintenance, which can improve convenience. One end of the limiting member 21 close to the flip plate 3 is attached with a shock-absorbing pad, which can play a role in shock absorption and noise reduction. Reinforcing ribs 34 are fixedly installed on the inner wall of the flip plate 3, and the setting of the reinforcing ribs 34 can play a supporting role.

[0030] The locking assembly 5 at least includes a base 51 fixedly installed on the cover plate 4. Accommodation holes 52 are opened on both sides of the base 51. An accommodation block 53 is pivotally installed in the accommodation holes 52. A claw 54 is fixedly installed on the accommodation block 53. A tongue 55 is provided on the flip plate 3. The claw 54 can be snapped into the slot of the tongue 55 to lock it. On the side of the accommodation block 53 away from the claw 54, a pull plate 56 is also pivotally installed. In the above, pulling the pull plate 56 can drive the claw 54 to move forward through the accommodation block 53 until the claw 54 is snapped into the tongue 55. The operation is simple and convenient, facilitating disassembly, replacement, and maintenance, and greatly improving work efficiency.
