Problems solved by technology

The gantry hydraulic lifting device is composed of a hydraulic lifting gantry steel frame and a hydraulic lifter connected to it. The gantry hydraulic lifting device is hoisted smoothly, but it can only vertically lift the equipment within the frame of the erected gantry. For large The use of ultra-high chemical equipment often requires the height of the portal steel frame to be a part higher than the height of the equipment. The degree of mechanized construction, safety and reliability of lifting and hoisting, and the performance of the portal steel frame are all reduced to varying degrees, which cannot be effectively used. The use performance of the mast, so that its application range is limited, has great limitations

Embodiment Construction

[0026] see Figure 1 to Figure 3 As shown, the double-tower low tower self-balancing lifting device of the present invention is composed of two separately arranged and left-right symmetrical tower mechanisms 1 and a U-shaped connecting truss 2;

[0027] The tower mechanism 1 includes the tower column 3 of the truss structure, the hoisting frame 4 of the truss structure, the hoisting beam 5 of the truss structure, the first hydraulic lifter 6, the second hydraulic lifter 7, the component clamping device 8 and the fixture 9 ;

[0028] The tower column 3 and the lifting sleeve frame 4 are vertically arranged on the ground and are fixedly connected with the ground. The bottom of the lifting beam 5 is connected, and at least one cable wind rope 11 is respectively connected to the front, rear, left and right four surfaces of the top of the tower column 3. Here, the cable wind rope 11 is determined according to the weather and the geographical location where the lifting device is in...

Abstract

The invention relates to a twin-tower low-pylon self-balancing lifting device belonging to the technical field of hoisting. The lifting device comprises two pylon mechanisms and a U-shaped connection truss, wherein the pylon mechanism comprises a pylon pillar and the like. The pylon pillar and a lifting stock are fixed on the ground; the upper end of the pylon pillar is connected with a hoisting beam after passing through the pylon pillar; the left end of the hoisting beam is provided with a member clamping device; a first hydraulic lifter is fixed on the ground; the steel stranded wire of the first hydraulic lifter is connected with the member clamping device; the hoisting beam is provided with a second hydraulic lifter; the steel stranded wire of the second hydraulic lifter is connected with a U-shaped clamp; and the U-shaped connection truss is connected with two pylon mechanisms. The invention solves the problems the traditional lifting device must be higher than equipment and the application range is narrow and adopts two pieces of suspended beam hoisting equipment and adopts a hydraulic lifting system to balance the load of the hoisting equipment, and therefore, the application range of the lifting device is wide and the lifting device is safe.

Description

technical field [0001] The invention relates to the technical field of hoisting and hoisting, in particular to a self-balancing lifting device for a double-tower low tower. Background technique [0002] With the development of production technology and requirements and the equipment manufacturing industry, large or even super-large equipment or components have appeared. Due to the limitations of site conditions, the weight of the equipment far exceeds the rated carrying capacity of conventional lifting equipment. Therefore, portal hydraulic The hoisting device has a prominent advantage in this respect and occupies a dominant position in the hoisting market. The gantry hydraulic lifting device is composed of a hydraulic lifting gantry steel frame and a hydraulic lifter connected to it. The gantry hydraulic lifting device is hoisted smoothly, but it can only vertically lift the equipment within the frame of the erected gantry. For large The use of ultra-high chemical equipmen...
