Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and particularly relates to a comprehensive platform for rapid joint pressing during installation of a pressure steel pipe. BACKGROUND

[0002] With the rapid development of modern water conservancy and hydropower engineering, the requirements for construction quality are increasingly strict, and construction technology needs to be continuously innovated. As a key water conveying component in a hydropower station, the installation quality of a pressure steel pipe directly relates to the safety and benefits of the entire project. The traditional pressure steel pipe installation method has problems such as a long construction period, high labor intensity, and difficult precision control, and has been difficult to meet the needs of modern engineering construction. Therefore, it is particularly urgent to develop an efficient, accurate, and rapid pressure steel pipe installation method.

[0003] The traditional pressure steel pipe installation method has many drawbacks: (1) The operation of the traditional installation process is relatively complex, the entire installation process takes a long time, and the work efficiency is low. Due to the lack of an efficient integrated operation mode, a large amount of time is consumed for each step, thereby lengthening the construction period. (2) The lack of advanced auxiliary equipment, the steel pipe installation often adopts a wedge pressing plate joint pressing process, the joint pressing precision is not high and is easy to cause a certain degree of damage to the base material, thereby affecting the overall strength and service life of the steel pipe. (3) The traditional installation method uses a simple construction platform for construction, and the disordered stacking of construction equipment becomes the norm, which is not conducive to the welding of the top girth joint, and the construction quality is difficult to guarantee.

[0022] The technical scheme of the embodiment of the present application is described in detail below in combination with the drawings.

[0023] A comprehensive platform for installing quick pressure joint of pressure steel pipe, comprising: a support base 2, a working platform 5, a positioning plate 4, a shaft pipe 6, a top pipe 8 and a jack 1. The support base 2 is provided with the working platform 5, the working platform 5 is assembled on site by using 8# channel steel, φ200mm galvanized steel pipe and galvanized steel grating as main materials, the working platform 5 is provided with a protective fence 7 on the outer side, the bottom is provided with a 10-inch rubber roller 3 as a moving and supporting, and the support base 2 is further provided with a storage platform 9. By designing the rubber roller 3 as a platform support, the comprehensive platform can move quickly in the inner wall of the pressure steel pipe, fully play the characteristics of plastic deformation of rubber material, and effectively protect the anticorrosive coating.

[0024] The positioning plate 4 is installed at both ends of the operation platform 5, so as to meet the full rotation of the jack 1 in the pressure steel pipe, realize the function of accurate pressing, and open the mounting hole with the same size on the positioning steel plate according to the size of the jacking pipe 8. The mounting hole is connected with the shaft pipe 6 through the bearing, the outer ring of the deep groove ball bearing is installed in the mounting hole, and the inner ring is sleeved on the shaft pipe 6. The positioning plate 4 is fixed in the middle of the comprehensive platform and connected through the shaft pipe 6 to keep the same horizontal height, so that it can rotate 360° around the connecting shaft steel pipe in the horizontal direction, thereby realizing the operation without dead angle.

[0025] The end of the shaft pipe 6 is threadedly connected with the jacking pipe 8 to form a "T-shaped" structure. In the subsequent use process, if the jacking pipe 8 or the shaft pipe 6 is damaged, one of the components can be replaced alone. The jacking pipe 8 is respectively installed with the jacks 1, and the screw jacks 1 are connected with the jacking pipe 8 to ensure the mechanical strength. The positioning plate 4 and the shaft pipe 6 are horizontally arranged on the comprehensive platform, so as to ensure that the jacks 1 can rotate around the axis in all directions and the stress is balanced in the pressing process, and the jacking pipe 8 will not be deformed due to uneven stress.

[0026] The shaft pipe 6 and the jacking pipe 8 are tightly connected through threads to form a relatively rigid whole structure. When the jacking pipe 8 is subjected to external force, the force will be transmitted to the shaft pipe 6 through the threaded connection. In the actual pressing process, the external force received by the shaft pipe 6 and the jacking pipe 8 is mainly the pressure along the axial direction, which can make the connection between the shaft pipe 6 and the jacking pipe 8 more closely, and limit the rotation of the shaft pipe 6 relative to the jacking pipe 8. At the same time, due to the supporting effect of the positioning plate 4 on the shaft pipe 6 and the stability of the whole comprehensive platform structure, when the shaft pipe 6 is subjected to the external force transmitted by the jacking pipe 8, it will be constrained by the positioning plate 4 and the platform structure, so that the shaft pipe 6 is fixed and no longer rotates when the jacking pipe 8 works.

[0027] In use, the jacks 1 are rotated to the pressing position, the construction personnel stand on the operation platform 5 to operate the screw jacks 1, so as to extend and support the pressure steel pipe, adjust the misalignment to achieve the pressing effect, and then weld and reinforce the pressing part directly when the misalignment meets the requirements. When the girth weld is welded, the comprehensive platform can be moved to the construction area, and the welding operation is carried out on the comprehensive platform.

[0028] According to the needs of the installation of the pressure steel pipe on site, different specifications of jacks 1, channel steels, galvanized steel pipes, rubber rollers 3 and other instruments can be selected. A safe, stable and movable comprehensive platform is provided for the installation, welding and construction equipment of the pressure steel pipe.
