Description

Technical Field

[0001] This utility model relates to the field of coking processing technology, and in particular to a tire-mounted crane traveling device. Background Technology

[0002] With the rapid development of China's economy, the demand for cranes in various industries such as heavy processing, logistics, and infrastructure construction is also increasing. As the construction of railway, highway, and light rail bridges in my country becomes more and more widespread, in order to meet the needs of railway, highway, and light rail bridge construction, traditional wheel-rail gantry cranes have outdated design concepts, limited operating conditions, simple system structures, and cannot fully meet the requirements of on-site construction as well as customers' needs for specialization, lightweight, high speed, automation, and intelligence.

[0003] Existing cranes generally use rigid connections or hydraulic suspension connections. Rigid connections cannot adapt to uneven surfaces. When lifting on uneven surfaces, they cannot automatically level, resulting in uneven tire stress and affecting their service life. While hydraulic suspension connections can adapt to uneven surfaces, they can only be adjusted laterally. In addition, they often use parallel wheels, which can easily cause tilting or jamming if one wheel encounters an obstacle (such as a step). Furthermore, they also have disadvantages such as high cost, high failure rate, and inconvenient maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a traveling device for a tire-mounted crane to solve the problems existing in the background art.

[0005] The technical solution of this utility model is implemented as follows: A tire-type crane traveling device includes a crossbeam and a frame. The bottom of the crossbeam is provided with two hinge seats. The bottom of each hinge seat is equipped with a balance beam through a hinge shaft. The two ends of the balance beam are vertically welded with columns. The bottom of the columns is bolted with a support plate through bolt A. The frame is installed at the bottom of the support plate. A pneumatic tire is installed at the bottom of the frame. A solid rubber tire is installed inside the pneumatic tire. A motor is installed on the inner frame and connected to the drive shaft of the pneumatic tire. The upper and lower parts of the outer frame are equipped with an upper bracket and a lower bracket. The upper and lower brackets are bolted with a bracket through bolt B. A protective plate is installed at the bottom of the bracket. Anti-collision strips are also installed at both ends of the top of the balance beam. Anti-collision plates are installed at the bottom of the crossbeam at positions perpendicular to the anti-collision strips.

[0006] Furthermore, the hinge seat and the hinge shaft are bolted together and fixed by a fixing device.

[0007] Furthermore, the hinge is connected to the upper middle position of the equalization beam.

[0008] Furthermore, the anti-collision strip is a semi-circular steel strip.

[0009] The beneficial effects of this utility model are as follows:

[0010] The crossbeam and equalizing beam of this utility model's traveling device are connected by a hinge, and it adopts a design with two sets of four tires arranged at the front and rear, allowing for independent up-and-down swinging. It has good adaptability to uneven terrain and good straight-line stability during travel. The combination of pneumatic tires and solid rubber tires ensures vibration reduction and drive during daily operation, while automatically switching when a pneumatic tire is damaged, providing emergency load-bearing and preventing equipment tilting and potential danger. In addition, the dual drive motors provide good driving power and avoid insufficient movement. Furthermore, the traveling device of this utility model has a simple structure and is easy to maintain.
