Description

Lifting device for steel roof truss hoisting of power plant main building

technical field

The utility model relates to a hoisting device in the field of thermal power engineering construction, in particular to a lifting device for hoisting a steel roof truss of a main factory building of a power plant.

Background technique

In the past construction of thermal power projects, since the installation height of the steel roof truss of the main factory building is generally more than 20 meters, large-scale lifting equipment must be used to hoist the steel roof truss. During the hoisting process, large-scale equipment needs to be frequently transferred, which leads to the There are many problems such as high cost, long construction period and low safety and reliability.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a steel roof truss hoisting device for the main building of a power plant with reasonable design, simple structure, convenient use, reduced cost, shortened construction period, and guaranteed construction safety.

The purpose of this utility model is achieved by the following technical means:

A lifting device for hoisting the steel roof truss of the main building of a power plant, characterized in that it includes a beam, a vertical beam and a support beam, the vertical beam is vertically installed on the beam, the support beam is arranged obliquely, and the two ends of the support beam are respectively installed on the beam and the beam. A tripod structure is formed on the vertical beams.

Moreover, a connecting beam is installed horizontally on the upper end of the vertical beam, and a suspension hook is installed on the connecting beam.

Moreover, the cross beams, vertical beams and support beams are all shaped steel.

Moreover, the connecting beam is shaped steel.

Moreover, the beams, vertical beams, supporting beams and connecting beams are installed together by welding or bolting.

Advantage and positive effect of the present utility model are:

1. The triangular frame body of the hoisting device is welded or bolted to each other by section steel, so the device is easy to assemble and use, and can be installed on site.

2. The frame body of the hoisting device can be assembled on site or on the bridge crane of the main workshop, and then the assembled hoisting device can be installed on the bridge crane of the main workshop, and finally with the help of the large boiler The hoisting equipment hoists the steel roof truss on the ground and hangs it on the inverted chain of the hoisting equipment that has been installed. Since the hoisting process of the steel roof truss of the main factory building is all in the field of vision of the construction personnel, the safety performance of using this device is more guaranteed than that of the previous large-scale hoisting equipment, which not only improves the utilization rate of the hoisting equipment, but also saves the project A lot of manpower, material resources and funds.

3. The frame body in this hoisting lifting device is a tripod system processed by section steel, which can ensure the stability of the lifting device. The beams, vertical beams, supporting beams and connecting beams in the hoisting and lifting device are all section steels. The selection of the section steels is flexible and diverse, and different section steel structures can be adopted according to the characteristics of the project. Install hooks on the upper part of the tripod that can meet the requirements of hoisting, and its strength must meet the needs of lifting equipment. The above structures can ensure that the device has sufficient hoisting strength and hoisting safety and stability, ensuring the smooth completion of the hoisting process.

4. The utility model is a lifting device with simple structure, scientific design and strong practicability for hoisting the steel roof truss of the main building of the power plant. And back and forth flexibility for hoisting steel roof trusses, using this device can reduce the re-investment and frequent transfer of construction machinery and equipment, ensure the safety of steel roof trusses in place, shorten the hoisting period and reduce construction costs.

Detailed ways

The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings; it should be noted that the present embodiments are descriptive, not restrictive, and cannot limit the protection scope of the present utility model with this.

A hoisting device for hoisting the steel roof truss of the main factory building of a power plant, including a beam 5, a vertical beam 4 and a support beam 3, the vertical beam is installed vertically on the beam, the beam is installed on the bridge crane 6, the support beam is installed obliquely, and the support beam The two ends of the frame are installed on the beam and the vertical beam respectively, and the beam, the vertical beam and the supporting beam form a tripod structure.

A connection beam 1 is installed horizontally on the vertical beam upper end, and a suspension hook 2 is installed on the connection beam, and the suspension hook is used for hanging and installing an inverted chain. The beams, vertical beams, supporting beams and connecting beams in this embodiment are all shaped steel, which are installed together by welding or bolting.

The use process of the present utility model is:

The hoisting lifting device can be assembled according to the specific size of the steel roof truss of the main factory building of the power plant. During the assembly process, with the help of hoisting machinery for hoisting the boiler, the processed configuration parts are assembled on the bridge suspension beam of the main factory building. All the connection parts are connected by welding or bolts, and the bridge crane is connected with the hoisting equipment by clamps; the assembly is completed Finally, hoist the assembled single steel roof truss 7 on the bridge suspension beam with the help of large-scale boiler hoisting equipment, fix the single steel roof truss on the hoisting equipment with the inverted chain on the assembled hoisting equipment, and then start the bridge hoist to Put the steel roof truss in place at the position, and carry out the other steel roof trusses in the above-mentioned manner.
