Description

TECHNICAL FIELD

[0001] The utility model relates to a hydraulic oil pump tractor for socket type steel pipe installation belongs to hydraulic engineering construction equipment technical field. BACKGROUND

[0002] The conventional method for installing spigot-and-socket steel pipes is as follows: After trench excavation and subgrade laying, the pipe is hoisted with nylon slings using installation equipment (such as a truck crane or excavator), and then manually transported to the installation location. During installation, the spigot-and-socket connection is typically made using an installation equipment or manually using a fall chain. For example, the invention patent application with publication number CN116951177A discloses an auxiliary installation device for large-diameter socket pipes and an installation method thereof. The auxiliary installation device includes a moving platform, a tightening mechanism, and a traction mechanism. Two conversion frames are provided on the moving platform, and a first wire shaft and a second wire shaft are provided between the two conversion frames. Two traction ropes are connected between the tightening mechanism and the traction mechanism, and a locking assembly is provided at both ends of each conversion frame; the position of the traction rope's fulcrum can be changed through the cooperation of the first wire shaft, the second wire shaft and the conversion frame, thereby changing the pulling direction of the traction rope; it can reduce friction and correct deviation, and when one end of the socket pipe is lifted, it ensures that the socket pipe is strictly centered; when the first wire shaft and the second wire shaft are at the bottom of the conversion frame, it is convenient for the socket pipe to be pushed in; during the installation process, only one person is required to control the traction mechanism, and one person is required to move the first wire shaft and the second wire shaft and to perform the final correction, thereby greatly reducing the convenience of manual use. For example, patent application publication number CN110131480A discloses a method for installing and butting a pressurized pipe with a socket joint. The method includes the following steps: pipe joint inspection: Before installing the pipe joint, an appearance inspection is performed, including checking the straightness and roundness of the pipe end, checking the standard of embedded parts, checking the smoothness of the pipe wall surface, and checking for cracks on the end face; pipe joint installation: selecting appropriate lifting and hoisting equipment and pipe installation equipment; installation sequence: either upstream to downstream or downstream to upstream installation for butt joint installation; construction process: pipe hoisting - pipe lowering - pipe stabilization - joint construction - quality inspection; pipe jointing: before installing the qualified pipe joint, the appearance, flatness, and structure of the socket joint are inspected, rubber rings are installed, lubricant is applied, and then installation is performed manually with the equipment, using a chain or hydraulic device. The lubricant used in the pipe jointing process is triglyceride. This method uses a lubricant with low fluidity, anti-static and dust-proof properties, and excellent lubrication and sealing effects, significantly improving the quality of the pipe joint installation. Each of the above technologies has its own characteristics and is suitable for different adaptive occasions. However, the use of installation tools for pipe socket connections is difficult because most installation tools are large machines with low operating precision. When pushing the pipe for the socket connection, it is difficult to accurately control the insertion depth. Inserting too deep may damage the rubber seal or the internal structure of the pipe, while inserting too shallow may lead to a loose interface connection and leakage. Manually using a chain to connect the pipe socket is slow, difficult to control installation precision, and extremely low installation efficiency. Utility Model Content
