Description

Technical Field

[0001] This utility model belongs to the field of lifting machinery technology, and in particular relates to an adjustable spacing horizontal wheel assembly. Background Technology

[0002] The design of crane horizontal wheels is primarily to reduce wear between the wheels and the rails. During crane operation, sliding friction may occur between the wheel treads and flanges and the rails, leading to severe wear. The design principle of horizontal wheels is to replace sliding friction with rolling friction, thereby significantly reducing wear.

[0003] The existing horizontal wheel mounting bracket and wheel axle mounting point have a waist-shaped hole for adjusting the distance between the horizontal wheel and the track. This method has a drawback: if the preload torque is applied incorrectly or the fastening nut loosens after long-term operation, the horizontal wheel will move to one side, causing the horizontal wheel to fail. In view of this, we propose an adjustable-distance horizontal wheel assembly. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable spacing horizontal wheel assembly to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an adjustable spacing horizontal wheel assembly, comprising:

[0006] The mounting frame has a fixed bracket on one side, and two strip grooves are opened on the top surface of the mounting frame. A wheel axle is slidably installed in each of the two strip grooves, and a horizontal wheel is rotatably installed on the outer side wall of each of the two wheel axles.

[0007] An adjustment assembly, which is mounted on a fixed frame and is used to drive two wheel axles to move;

[0008] A side frame is fixedly installed on one side of the mounting frame. Two movable plates are slidably installed inside the side frame, and a cleaning brush is fixedly installed on the side of the two movable plates that are close to each other.

[0009] A movable component is disposed within the side frame and is used to move two movable plates.

[0010] In the above technical solution, the adjusting component further includes two side grooves, which are respectively opened on both sides of the fixed frame. The fixed frame and the mounting frame are rotatably mounted with the same lead screw. A threaded sleeve is threadedly connected to the lead screw. Fixed seats are fixedly mounted on both sides of the threaded sleeve. Two movable seats are slidably mounted on the top surface of the mounting frame. The top ends of the two wheel axles are fixedly connected to the bottom surfaces of the two movable seats. Connecting rods are rotatably mounted in the two fixed seats. The bottom ends of the two connecting rods pass through the two side grooves and are rotatably mounted in the two movable seats. When the threaded sleeve moves, the movable seats will move through the cooperation of the connecting rods and the fixed seats. The movement of the movable seats will drive the wheel axles to move, thereby realizing the adjustment of the position of the horizontal wheels and controlling the distance between the two horizontal wheels so that the distance between the two horizontal wheels can be adapted to different specifications of tracks.

[0011] In the above technical solution, a motor B is further fixedly installed on the top surface of the fixed frame. The bottom end of the output shaft of the motor B is fixedly connected to the top end of the lead screw. When the motor B is started, it drives the lead screw to rotate. When the lead screw rotates, it will drive the threaded sleeve to move on the lead screw.

[0012] In the above technical solution, the moving component further includes an inner cavity, which is disposed within a side frame. Two racks are slidably installed within the inner cavity. Two sliding grooves are formed on the side wall of the side frame, and sliders are slidably installed in each of the two sliding grooves. The top ends of the two sliders are fixedly connected to the bottom surfaces of the two racks, and the bottom ends of the two sliders are fixedly connected to the top surfaces of the two moving plates. When the two racks move, the two sliders will drive the two moving plates to move, thereby controlling the distance between the two moving plates and making the cleaning brushes on the two moving plates contact the sides of the track to clean the sides of the track.

[0013] In the above technical solution, the moving component further includes a gear, which is rotatably installed in the inner cavity. Two racks are located on both sides of the gear and mesh with the gear. A motor A is fixedly installed on the top surface of the side frame. The bottom end of the output shaft of the motor A is fixedly connected to the top end of the gear. When the motor A is started, it drives the gear to rotate. When the gear rotates, it drives the two racks to move, causing the two racks to move in opposite directions.

[0014] Furthermore, in the above technical solution, the side frame has a U-shaped structure.

[0015] In the above technical solution, a plurality of mounting holes are provided on one side of the mounting bracket, which facilitates the installation of the mounting bracket.

[0016] The beneficial effects of this utility model are:

[0017] 1. This adjustable-gap horizontal wheel assembly allows for adjustment of the two horizontal wheels according to the spacing of different tracks. When adjusting the spacing of the two horizontal wheels, the motor B is started to drive the lead screw to rotate. When the lead screw rotates, it drives the threaded sleeve to move on the lead screw. When the threaded sleeve moves, it drives the moving seat to move through the cooperation of the connecting rod and the fixed seat. The movement of the moving seat drives the wheel axle to move, thereby realizing the adjustment of the position of the horizontal wheels and controlling the spacing of the two horizontal wheels to adapt the spacing of the two horizontal wheels to different track specifications.

[0018] 2. The adjustable-gap horizontal wheel assembly can start motor A to drive the gear to rotate according to the width of the track. When the gear rotates, it will drive two racks to move, causing the two racks to move in opposite directions. When the two racks move, they will drive two moving plates to move through two sliders, thereby controlling the gap between the two moving plates, so that the cleaning brushes on the two moving plates contact the two sides of the track to clean the two sides of the track.
