The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated structures on both sides, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment, and has high stability. However, since high-stability cranes travel in the air for a long time, it is not very convenient to overhaul and maintain them. In order to improve their usability, it is necessary to provide a lubrication mechanism on the traveling wheels. Based on this, the utility model proposes a high-stability crane.

[0021] like Figure 1-5As shown, a high stability crane comprises a crane base 3, a motor 4 is mounted on the crane base 3, the motor 4 is connected to an output shaft through a coupling 5, the output shaft is connected to a reduction box 6, the reduction box 6 is connected to a winch 7, and a guide wheel 8 is mounted at the bottom of the base 3 below the winch 7. The wire rope is wound around the winch 7 and connected to the sling after passing through the guide wheel 8.

[0022] A plurality of running wheels 9 are installed at the bottom of the crane base 3, and a lubricator 10 is installed on the running wheels 9. The lubricator 10 includes a tank body 101, and an oil drain sheet 102 is slidably installed in the tank body 101. A central shaft 104 is installed at the center position of the upper end surface of the oil drain sheet 102, and the central shaft 104 is in sliding contact with the top of the tank body 101. A spring 103 is sleeved on the central shaft 104, and one end of the spring 103 abuts against the upper end of the oil drain sheet 102, and the other end abuts against the top of the tank body 101. The elastic force of the spring 103 presses the oil drain sheet 102 downward, and the oil drain sheet 102 exerts a force downward on the lubricating oil, so that the lubricating oil is discharged. An oil outlet hole 105 is installed at the bottom of the tank body 101, and the end of the oil outlet hole 105 is connected to an oil outlet pipe 106. A brush 107 is installed at the end of the oil outlet pipe 106. The brush 107 is against the running wheel 9. During the running of the running wheel 9, the brush 107 applies lubricating oil on its surface to reduce friction and noise.

[0023] The oil outlet pipe 106 is made of a metal bellows material, and its angle can be changed at will.

[0024] The crane base 3 is slidably mounted on the vertical traveling beam 2 via a traveling mechanism, and the traveling mechanism can also be equipped with a lubricator 10 .

[0025] The vertical walking beam 2 is slidably mounted on the transverse walking beam 1 via a walking mechanism, and the walking mechanism can also be equipped with a lubricator 10.

[0026] A guardrail is installed on the transverse walking beam 1, and walking components are installed at both ends of the transverse walking beam 1. The walking components are used for sliding connection to the slide rails on the factory wall.

[0027] The lubrication process of the utility model is as follows:

[0028] The elastic force of the spring 103 presses the oil drain plate 102 downward, and the oil drain plate 102 exerts a force downward on the lubricating oil, and the lubricating oil is discharged from the oil outlet hole 105 to the oil outlet pipe 106, and finally reaches the brush 107 at the tail end of the oil outlet pipe 106. The brush 107 applies the lubricating oil on the surface of the running wheel 9 during the running process, thereby reducing friction and lowering noise.

[0029] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
