[0004] The existing double-beam bridge crane has the following problems: For example, fixed installation requires a more demanding installation environment; when the installation position is higher, the crane's working stroke is longer and the efficiency becomes lower; when the installation position is lower, it is difficult to reach the target lifting height. For this reason, we propose a double-beam bridge crane. Utility Model Content

[0009] Height adjustment mechanism: It is set at the front and rear ends of the lifting support beam and can be adjusted in height. When the installation height is low, the height is raised to reach the lifting height. When the installation height is low, the height is lowered to reduce the working stroke and improve work efficiency.

[0010] Furthermore, the height adjustment mechanism includes a fixed support frame and a connecting frame. The front and rear ends of the lifting support beam are fixedly connected to the connecting frame, and the interior of the connecting frame is fixedly connected to the fixed support frame to provide support for the operation of the equipment.

[0012] Furthermore, the height adjustment mechanism also includes an installation support frame and a fixed frame. The outer surface of the lower end of the hydraulic lifting column is fixedly connected to the fixed frame, and a installation support frame is fixedly connected between the lower surfaces of the two fixed frames on the same side to provide a stable working environment.

[0013] Furthermore, it also includes a walking support plate, which is fixedly connected to the left side surface of the left lifting support beam and can be used by workers to walk.

[0014] Furthermore, a guardrail is fixedly connected to the left end of the upper surface of the walking support plate to provide protection when walking.

[0015] Furthermore, the upper surface of the mounting support frame is provided with evenly distributed bolt connection ports to facilitate quick installation.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the bridge type double beam crane has the following advantages:

[0017] When it is necessary to adjust the height of the double-beam bridge crane, the staff can input hydraulic oil into the hydraulic lifting column through the hydraulic pump, and the telescopic ends of the hydraulic lifting columns move upward synchronously and in the same amplitude, the telescopic ends of the hydraulic lifting columns drive the lifting support beam upward, the lifting support beam drives the lifting crane upward, the lifting crane drives the support frame upward, and the support frame drives the electric hoist upward. In this way, the height of the lifting support beam can be adjusted after installation, so that the lifting height can still be guaranteed when the installation position is low, and the height can be adjusted to lower the installation height when the installation position is high, so as to adapt to more complex lifting working environments.
