Problems solved by technology
[0004] In order to solve the problem of frequent steering of forklifts in the existing technology, the temperature of the steering column of the forklift is likely to rise during use, which aggravates the wear of the steering column of the forklift, and the increase of the temperature of the column will affect the safety of the cylinder. , the heat resistance of the pipe column also affects the service life of the pipe column. The invention provides a high temperature resistant forklift steering column assembly

The invention discloses a high-temperature-resistant forklift steering pipe column assembly. The high-temperature-resistant forklift steering pipe column assembly comprises a first sleeve, a pluralityof straight pipes and bend pipes which are used for heat conduction are arranged on the outer wall of a cooling fin, a third sleeve is arranged outside the first sleeve, and second fixed blocks are arranged on the inner wall of the third sleeve and the third sleeve is fixedly connected with a heat dissipation pipe through the second fixed blocks. A plurality of through holes used for spraying water are formed in the outer side of the heat dissipation pipe at equal intervals. The high-temperature-resistant forklift steering pipe column assembly can absorb the heat generated by the second sleeve during rotating friction through the cooling fin, through the straight pipes and the bend pipes, the heat from the cooling fin can be absorbed to reduce the temperature inside the first sleeve to protect the first sleeve, the flow of water entering into the heat dissipation pipe forms a water curtain, the water curtain can absorb the heat inside the third sleeve and can effectively improve the heat insulation ability of the third sleeve, and the high-temperature-resistant capacity inside the third sleeve is improved.
Description
technical field [0001] The invention relates to a forklift pipe column, in particular to a high temperature resistant forklift steering pipe column assembly. Background technique [0002] When the forklift is turning, the driver applies the steering torque on the steering wheel to generate a rotational displacement of the steering wheel, which is transmitted to the steering gear through the steering shaft. The steering gear measures the pressure oil diverted from the diverter valve through the pipeline according to the angle of rotation of the steering wheel. Give the steering cylinder, and then drive the steering wheel through the steering body to realize the steering. [0003] Due to the frequent steering of the forklift, the temperature of the forklift steering column is likely to rise during use, which aggravates the wear of the forklift steering column, and the temperature rise of the forklift will affect the safety of the oil cylinder. The heat capacity also affects t...
