Description

Technical Field

[0001] The invention relates to the technical field of floor-standing pole holding devices, and in particular to a self-balancing double-rocker arm floor-standing pole holding device balancing mechanism. Background Art

[0002] With the development of power transmission network construction, the construction of large-scale steel structure projects such as power towers is increasing. In the construction process of large-scale steel structure projects such as power towers, ground-mounted double-rocker arm hoisting equipment is generally used. The so-called ground-mounted double-rocker arm tower body is assembled from several standard sections, upper and lower supports, and masts from bottom to top, and the two rockers are symmetrically installed at the upper support of the tower body.

[0003] The prior art publication number CN216303103U discloses a 750×750mm cross-section lightweight double rocker arm with controllable verticality, comprising: a main frame, on the top of which are fixedly mounted an angle limiting mechanism, a stable pulling mechanism and a pulley assembly changing mechanism. In the process of pulling objects, the fixed plate on the top of the device is affected by pressure and will shift its position, driving the connecting plate connected thereto to rotate on the mounting plate. At this time, when the offset angle is too large, the L-shaped stopper on the connecting plate will contact the inner wall of the limiting ring groove and limit the top structure of the device to prevent the occurrence of unstable workmanship due to a large rotation amplitude. The above conditions solve the problem of poor overall coordination between the rocker arm and the auxiliary arm of the existing device, and use the same rotation speed of two servo motors to make the contraction rate of the wire lifting rope equal, so that the device can maintain the maximum load-bearing range and increase work efficiency.

[0004] However, the following defects still exist: the entire device is supported only by the main frame. When the rocker arm is long, the overall support stability is poor. Therefore, it is necessary to design a self-balancing double rocker arm ground-mounted arm balancing mechanism to solve the above problem. Summary of the invention

[0005] The purpose of the present invention is to provide a self-balancing double rocker arm ground-mounted holding rod balancing mechanism to solve the above-mentioned problems.
