Problems solved by technology

[0002] After the installation of thermal pipelines and equipment hangers in factories, buildings, etc., the elevation of the equipment under the hanger must be adjusted. By adjusting the height of the hanger’s hanger, the equipment under the hanger can reach the design elevation. Currently, it is common to adjust the height of the hanger and equipment Use a chain hoist to raise the height of the equipment under the boom, and then adjust the height of the boom. This method has many procedures, and the equipment elevation cannot be adjusted at one time. The construction personnel need to adjust the calibration equipment and the elevation of the boom many times. cumbersome and dangerous

Abstract

The invention relates to a hanging rod lifting device which comprises a bottom plate, two supporting bases arranged on the two sides of the upper end of the bottom plate, an adjusting plate with the bottom installed on the supporting bases through a hinge pin II in a rotating mode, an ejecting support arranged at the upper end of the bottom plate, and two jacks arranged below the ejecting support and located on the two sides of the bottom plate. Two movable connecting devices are fixed to the lower end of the ejecting support. The sliding plate is fixed in the movable connecting devices in a sliding mode. A hole with the diameter larger than the outer diameter of a hanging rod is formed in the middle of the bottom plate. The hanging rod penetrates through the hole and is then locked through a nut. The hanging rod can drive the ejecting support to rise or fall through the jacks after being fixed to the bottom plate through a nut. The movable connecting devices drive the bottom plate through the adjusting plate to drive the hanging rod so that the ejecting support can rise and fall, and therefore the elevation of devices under the hanging rod can be conveniently adjusted. Thus, the defect that a traditional chain block can not be conveniently adjusted is overcome, and safety is improved.

Description

technical field [0001] The invention relates to a height raising device for a suspender of a hoisting device. Background technique [0002] After the installation of thermal pipelines and equipment hangers in factories, buildings, etc., the elevation of the equipment under the hanger must be adjusted. By adjusting the height of the hanger’s hanger, the equipment under the hanger can reach the design elevation. Currently, it is common to adjust the height of the hanger and equipment Use a chain hoist to raise the height of the equipment under the boom, and then adjust the height of the boom. This method has many procedures, and the equipment elevation cannot be adjusted at one time. The construction personnel need to adjust the calibration equipment and the elevation of the boom many times. Complicated and dangerous. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a boom lifting device with ...
