Description

Technical Field

[0001] This utility model relates to the field of crane accessories technology, and more specifically to a wear-resistant crane travel wheel set. Background Technology

[0002] A gantry crane, also known as a portal crane or gantry hoist, is a type of lifting equipment with a gantry frame structure. It mainly consists of a gantry frame, traveling mechanism, hoisting mechanism, luffing mechanism, and slewing mechanism. Depending on its application and structure, gantry cranes can be classified into various types, including fixed, mobile, single-girder, and double-girder types.

[0003] The traveling mechanism on a gantry crane is often slidably positioned by wheels and the brackets connected to the wheels. When lifting goods, the wheels bear a lot of force. In order to prevent the wheel axles from being deformed due to pressure, the existing traveling mechanism is generally equipped with multiple wheels to distribute the pressure. However, this will result in the overall volume of the brackets connected to the wheels being large, which will affect the travel. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a wear-resistant traveling wheel set for cranes.

[0006] To achieve the above objectives, the technical solution of this utility model is: a wear-resistant traveling wheel set for cranes, comprising: an integrally formed U-shaped traveling wheel frame, a winding motor, and a sling; the winding motor is fixedly connected to the bottom end of the U-shaped traveling wheel frame; the sling is connected to the output end of the winding motor;

[0007] The U-shaped traveling wheel frame has an opening facing upwards, and a wheel groove is provided on both sides of the inner wall of the opening. At least one wheel can rotate in the wheel groove. An auxiliary positioning component is horizontally installed on the inner side of the middle section of the U-shaped traveling wheel frame to contact and position the bottom surface of the gantry crane beam, so as to reduce the load on the wheels.

[0008] The auxiliary positioning component includes a roller and two fixed rods that are respectively fixedly connected to the inner wall of the middle section of the U-shaped walking wheel frame. The roller rotates horizontally between the two fixed rods, and the ends of the fixed rods facing the roller are provided with adjustment mechanisms for the rotation positioning and position adjustment of the roller.

[0009] Preferably, for ease of adjustment, the adjustment mechanism includes a lifting groove with its opening facing the roller, an adjustment shaft that slides horizontally within the lifting groove, and an adjustment bolt screwed to the bottom of the lifting groove. The end of the adjustment shaft away from the lifting groove is rotatably embedded in the center of the roller end face. The top of the adjustment bolt extends vertically into the lifting groove and contacts the bottom surface of the adjustment shaft for supporting and adjusting the adjustment shaft.

[0010] Preferably, for rotational positioning, the end of the roller is provided with a bearing that is rotatably connected to the adjusting shaft.

[0011] Preferably, in order to improve the contact effect with the bottom surface of the gantry crane beam, the outer wall of the roller is provided with a smooth or frosted rolling sleeve.

[0012] Preferably, the inner wall of the lifting groove is provided with a slide rail to prevent the adjusting shaft from shifting during vertical sliding.

[0013] As a preferred option, to improve the strength of the connection, the winding motor and the U-shaped traveling wheel frame are connected by either welding or bolting.

[0014] As a preferred option, a hook is provided at the bottom of the sling for lifting the goods.

[0015] Preferably, the rollers are positioned below the wheels to allow for sliding clamping at the bottom of the beam of the I-beam gantry crane.

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

[0017] 1. The auxiliary positioning component, in conjunction with the sliding clamps of the wheels, is attached to the bottom of the gantry crane's crossbeam. After initial installation, workers use tools to screw in the adjusting bolts, causing them to spiral upwards. During this upward movement, the adjusting shaft is lifted, causing it to move the rollers upwards to contact the bottom surface of the gantry crane's crossbeam for auxiliary support and positioning. This reduces the load on the wheels. Compared with existing technologies, this method can still function normally even with a reduced number of wheels. It also reduces the size of the U-shaped traveling wheel frame, increases the travel distance, and prevents goods from being mishandled.

[0018] 2. The roller is connected to the adjusting shaft in a rotating manner. When the U-shaped walking wheel frame moves, the roller will also roll. The rolling sleeve on its outer wall has the function of improving wear resistance. Attached Figure Description
