Mobile assembling gantry crane

Abstract

The invention discloses a movable assemble type gantry crane, which is characterized in that the gantry crane comprises two base beams (5), and two ends under every base beam (5) are respectively connected with universal combined wheels (6), and the middle part of every base beam (5) is respectively fixed with a lower pillar (4) by a bolt, and an upper pillar (3) is connected in the lower pillar(4), and the two ends of every base beam (5) are respectively provided with hand cranking wire tightening devices (8), and a wire rope of the hand cranking wire tightening device (8) is fixed on the top end of the upper pillar (3), and the upper pillar (3) is connected with an upper beam (1), and a slide spreader (2) is hung on upper beam (1). The invention is simple in structure, safe and reliable and fast in assembly, and is suitable in hanging of different environment equipment indoor, can finish repairing with good quality and high efficiency within the set time, thus reducing the cost and enhancing the working efficiency.

Description

Technical field: [0001] The invention relates to a mobile assembled gantry crane, which belongs to the technical field of power system substation maintenance. Background technique: [0002] With the continuous and rapid development of power grid construction, many substations need to be expanded and increased in capacity. After the initial construction of the indoor substation, the original method of operation is used, and the ground is laid with floor tiles. After the equipment is hoisted into the room, it cannot be transported in place. , use the rollers to roll a little bit, and it takes 8-10 people to work for nearly a day to carry a space, which is neither safe nor affects the progress of the project; during the hoisting and docking of equipment, the construction personnel must stand on the 6-meter ladder, which cannot be tied safely. In the case of a belt, use a rod to pass the traction rope through the reserved ring on the roof about 10 meters high, then pass the wire...

Problems solved by technology

[0002] With the continuous and rapid development of power grid construction, many substations need to be expanded and increased in capacity. After the initial construction of the indoor substation, the original method of operation is used, and the ground is laid with floor tiles. After the equipment is hoisted into the room, it cannot be transported in place. , use the rollers to roll a little bit, and it takes 8-10 people to work for nearly a day to carry a space, which is neither safe nor affects the progress of the project; during the hoisting and docking of equipment, the construction personnel must stand on the 6-meter ladder, which cannot be tied safely. In the case of a belt, use a rod to pass the traction rope through the reserved ring on the roof about 10 meters high, then pass the wire rope through it, and use the reverse chain to carry out lifting operations. Sometimes affected by the lifting height, people must stand on the lifting equipment. There is a great potential safety hazard in the operation of the chain-down operation. Due to the difficulty of climbing and hanging the sling, the operation time cannot be determined, especially during the power outage docking, which caused problems such as long power outage, high labor intensity, and high manpower and material resources. The completion of the project has brought difficulties; using the modified workbench to operate, since only iron lifting devices need to be installed on the existing maintenance platform, although it is easy to implement and low in cost, the transformation of the workbench and the simulation equipment On-site tests of positioning and docking found that the original handling method was still used for equipment handling, and it was time-consuming and inefficient in the process of setting up the workbench and dismantling. ensure
