Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a car deflection prevention device for a backpack type elevator. Background Art

[0002] A home elevator is an elevator installed in a private residence for use by a single family member. The structure of a private house saves construction costs and construction space to the maximum extent, while taking into account the appearance and aesthetics of the house. At present, home elevators cannot meet the installation requirements of ordinary passenger elevators due to problems such as narrow shaft size and low floor height. However, a backpack home elevator has been launched on the market. Its car mainly consists of a car body, a rope pulley set and a car frame, which can meet the requirements of installing a relatively large elevator with a small shaft area.

[0003] The patent specification with the announcement number CN219009639U discloses a car deviation prevention device for a backpack elevator, which includes a car and a car frame fixed outside the car, a limiting member with an upper groove is provided on each side of the car, and a limiting plate is provided on both sides of the car frame for inserting into the upper groove to limit the left and right movement of the car. It can limit the left and right position of the car by using the limiting member with the upper groove to cooperate with the limiting plate, thereby avoiding the left and right shaking and deviation of the car, and ensuring the safety and reliability of the backpack elevator.

[0004] However, in the implementation of relevant technologies, it was found that the anti-deviation device of the car of a backpack-type elevator designed as above has the following problems: in the above technical solution, a limit piece with an upper groove can be used in conjunction with a limit plate to limit the left and right position of the car, thereby avoiding left and right swaying and deviation of the car, and ensuring the safety and reliability of the backpack-type elevator. However, under the action of the eccentric load force formed by the car load of the backpack-type elevator, the car guide block and the guide rail are subjected to great force and friction, which affects the smoothness of operation. In view of this, a backpack-type elevator car anti-deviation device is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a car anti-deviation device for a backpack type elevator.

[0007] As a further description of the above technical solution: guide grooves are provided inside the two elevator guide rails, and guide bars fixedly connected to the reinforcement frame are slidably connected inside the guide grooves. Through the guide grooves in the elevator guide rails, with the cooperation of the guide bars, a guiding function can be achieved.

With the cooperation of the pull rope, the right side of the reinforcement frame can be tightened, thereby further strengthening the car body and avoiding deviation of the car body.

[0010] As a further description of the above technical solution: a mounting piece is fixed to the upper surface of the two reinforcement frames, and the internal thread of the adjustment block is connected to an adjusting screw. The end of the adjusting screw is rotatably connected to the inner wall of the mounting piece through a bearing. By twisting the adjusting screw on the mounting piece, the threaded adjustment block can be driven to move horizontally, thereby adjusting the tightness of the pull rope.

[0011] As a further description of the above technical solution: a limiting plate is fixed on the upper surface of the adjusting block, and a limiting bolt is threadedly connected to the upper surface of the limiting plate. The limiting bolt on the limiting plate can be unscrewed to release the fixation of the pull rope, thereby facilitating the replacement of the pull rope.

[0014] The utility model designs a car deflection prevention device for a backpack type elevator. Through a mounting frame arranged on the deflection prevention member, a guide wheel on the guide member contacts the back side of the elevator guide rail, thereby limiting the car body, thereby playing a certain load role, thereby reducing the force between the car guide block and the guide rail, reducing the friction, and through the rubber sleeve on the guide wheel, it can play a noise reduction role, avoiding the guide wheel from directly contacting the elevator guide rail to cause noise.

[0015] The utility model designs a car deviation prevention device for a backpack-type elevator. The connecting block can be fixed by a fixing plate arranged on a guide bar, so that the car body can be tightened conveniently. With the cooperation of a pull rope, the right side of the reinforcement frame can be tightened, so that the car body is further strengthened to avoid deviation of the car body. The adjusting screw on the mounting part can be turned to drive the adjusting block connected by the thread to move horizontally, so that the tightness of the pull rope can be adjusted.
