Description

Technical Field

[0001] The utility model relates to the technical field of traction cranes, in particular to a crawler type traction crane for slope lining construction. Background Art

[0002] The rolling of slope cushion materials and the construction of slope lining panels are key links in the construction of pumped storage power station banks and other earth-rock dams. The construction quality directly affects the construction quality of reservoir anti-seepage panels. During slope construction, tractors are often needed to drive rolling wheels, lining trolleys and other equipment on the slope by traction. When in use, tractors are mostly located at the top of the slope, using the tractor's own gravity to tow the construction equipment to maintain construction on the slope.

[0003] For example, the Chinese invention patent with publication number CN113718747A discloses a crawler-type slope roller, which relates to the technical field of infrastructure construction equipment and solves the problems of poor stability of the tractor and uncontrollable direction of the roller in the prior art. The invention includes a tractor, a rolling mechanism, a steering mechanism and a swing arm mechanism. The rolling mechanism is hinged to the steering mechanism, and the swing arm mechanism is arranged on the tractor. The tractor is connected to the steering mechanism through a traction rope arranged on the swing arm mechanism. The invention adopts an auxiliary bracket to cooperate with the tractor, which can further increase the stability of the tractor on the slope and prevent it from slipping; the steering mechanism adopts a telescopic cylinder symmetrically arranged on both sides, which can form a stable traction direction and avoid repeated rolling. At the same time, it can also perform steering operations within a certain range to improve the rolling efficiency.

[0004] In this solution, the auxiliary bracket is inserted into the ground for support and anti-skid purposes to improve stability. In actual use, since most slopes are newly built, the auxiliary bracket inserted into the slope at the top of the slope will damage the integrity of the slope. The tractor is set closer to the side, which is prone to landslides due to insertion and pressure from the single-side track. Therefore, the tractor in the prior art has low stability and reliability when in use, and after the construction is completed, it does not have a lifting function, and it is not easy to recover the towed equipment.
