Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a novel auxiliary trolley for a grease injection gun. Background Art

[0002] Daily maintenance of valves often involves grease injection. Currently, the commonly used grease injection equipment mainly consists of grease injection guns and grease injection machines, which are applicable to different scenarios. Compared with grease injection machines, grease injection guns have the advantages of small size, simple and convenient operation, and no need for external power source. They are mainly used for maintenance of small-sized valves and in situations where the operating space and power source are limited.

[0003] Due to the differences in the grease injection positions of valves, for valves with relatively high grease injection holes, it is necessary to find a supporting plane for placing the grease gun to facilitate the grease injection operation. However, the existing grease gun is a separate gun body, and the supporting position of the gun body is often unable to be found in actual work. Additional personnel are required to assist in lifting the grease gun and adjust the position and angle of the grease gun as the grease injection position changes, which causes inconvenience in operation. Utility Model Content

[0019] With this structure, the height of the first support plate can be quickly adjusted by driving the rocker.

[0020] Through the above technical solution, the grease gun is fixed by two gun racks, so that the grease gun has a fixed supporting position, and the corresponding oil pipe can also be fixed on the oil pipe rack. According to the height and angle of the grease injection position, the height of the first support plate can be adjusted by the lifting mechanism, the relative position of the second support plate can be adjusted by the sliding mechanism, and the angle of the second support plate can be adjusted by the rotating structure, so as to meet the grease injection needs at different heights and angles. At the same time, grease injection related materials and tools can be stored inside the locker. Each time grease is injected, the auxiliary cart only needs to be pushed to the grease injection point, which solves the problem of no supporting platform and material carrying when the grease gun is performing grease injection operation, and greatly improves work efficiency.
