[0002] In the existing industrial installation project, when the equipment in the frame is installed, it is impossible to use the crane to directly lift it into place, and the installation position is between the beams. The hoisting method often uses multiple anchor points and multiple appliances (chain hoists, Jack, wire rope, hoist, etc.), dragging, pulling, dragging and other methods to install the equipment in place is labor-intensive and time-consuming, and it is not safe and reliable; For the hoisting of equipment on the bottom or lower floors of the structure, the crane must be hoisted through the hoisting port of the highest frame, the performance of the crane needs to be greatly increased, and the cost is quite high. unable to work

Embodiment Construction
[0029] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a gantry crane system in a frame includes a gantry 1, a power system 2 and a hoisting system 3. The gantry 1 includes a crossbeam 11, a hanging plate 12 and two supporting frames that are arranged parallel to each other connecting the two ends of the crossbeam 11. The support frame includes a column 13, a base beam 14 and two diagonal braces 15. The upper end of the column 13 is fixedly connected to one end of the beam 11, the lower end of the column 13 is vertically fixedly connected to the middle part of the base beam 14, and the two ends of the base beam 14 are connected to the column. The upper ends of 13 are respectively symmetrically provided with diagonal braces 15, the upper end of the hanging plate 12 is fixedly connected with the middle part of the beam 11, the lower end of the hanging plate 12 is provided with a mounting hole for installing lifting equipment, and the two sides of the upper end ...

An intra-frame portal crane system comprises a portal frame, a power system and a hoisting system. The portal frame comprises a crossbeam, a hanger plate and two parallel supporting frames connected with the two ends of the crossbeam. Each supporting frame comprises a stand column, a base beam and two inclined struts. The upper end of each stand column is fixedly connected with one end of the crossbeam, and the lower end of each stand column is perpendicularly and fixedly connected with the middle of the corresponding base beam. The inclined struts are arranged between the two ends of each base beam and between the upper ends of the stand columns symmetrically. The upper end of the hanger plate is fixedly connected with the middle of the crossbeam. The power system comprises a pulley block, a moving rope, a winch, a traction pulley, a lifting hook and a buckle. The hoisting system comprises two steel wire ropes, a balance beam and a device to be hoisted. The intra-frame portal crane system is simple in structure, easy to manufacture, convenient to assemble and disassemble, high in circulation using efficiency, low in cost, and capable of easily and effectively achieving the purpose of hoisting the device in a frame and lowering construction cost. The invention further provides a hoisting use method of the portal crane system.
Description
technical field [0001] The invention relates to the technical field of industrial hoisting, in particular to an in-frame gantry crane system and a hoisting and using method thereof. Background technique [0002] In the existing industrial installation project, when the equipment in the frame is installed, it is impossible to use the crane to directly lift it into place, and the installation position is between the beams. The hoisting method often uses multiple anchor points and multiple appliances (chain hoists, Jack, wire rope, hoist, etc.), dragging, pulling, dragging and other methods to install the equipment in place is labor-intensive and time-consuming, and it is not safe and reliable; For the hoisting of equipment on the bottom or lower floors of the structure, the crane must be hoisted through the hoisting port of the highest frame, the performance of the crane needs to be greatly increased, and the cost is quite high. Unable to work. Contents of the invention ...
