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

[0024] see Figure 1 to Figure 3 As shown, the double-tower low tower 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;

[0025] 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 ;

[0026] 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 installed. 11 Th...

Abstract

The invention discloses a construction method for hoisting by using a double-tower low-pylon self-balanced elevating device, which belongs to the technical field of hoisting. During construction, the lower part of a hoisting rope buckle is connected with a main lifting lug of equipment, while the upper part is connected with a U-shaped clamp; and the tail part of the equipment is connected with a rope by a crane and vertically moves forward along with the head part of the equipment until the equipment is fully erected and positioned on the ground. During the hoisting and erecting of the equipment, the method is not limited by space, has wide using range and is safe.

Description

technical field [0001] The invention relates to the technical field of hoisting and hoisting, in particular to a construction method for hoisting and hoisting using a double-tower low tower self-balancing hoisting device. 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. F...
