Description

Technical Field

[0001] The utility model belongs to industrial pipeline installation facilities, and particularly relates to the precision control of the height and levelness in the installation construction of pipeline fittings and valves during the industrial pipeline installation project stage. Background Art

[0002] In industrial pipeline installation projects, the connection between equipment is generally composed of pipe fittings, valves, flexible joints, check valves, etc. During the installation process, these pipe fittings and valves need to be connected through short pipes and flanges. During this process, each component needs to be fixed in a position and assembled through flange bolts. And for large power stations, their valve pipe fittings are relatively heavy. In traditional industrial pipeline installation construction, workers usually look for support points near the installation pipeline and use electric hoists or chain hoists to transport the required pipe fittings or valves to the required positions. Using this method is time-consuming and laborious during the construction process, and when there is no support point at a special position, manual installation is required, which not only has greater safety hazards but also requires continuous adjustment of the position during the installation process. Summary of the Invention

[0003] The utility model solves the problems of convenience and safety during the transportation and installation of valves and pipe fittings in current industrial pipeline installation construction.

[0004] The technical solution of the utility model:

[0005] A portable large pipe fitting installation auxiliary hydraulic lift truck, including a rechargeable mobile hydraulic lift, characterized in that a hammer-back clamp is installed on the rechargeable mobile hydraulic lift; the hammer-back clamp is composed of two groups of claws, a cross bar, a hydraulic piston, and a fixed base; the lower part of the fixed base is fixedly connected to the platform of the rechargeable mobile hydraulic lift, the upper part of the fixed base is connected to the cross bar, one end of the cross bar is connected to a group of claws, the other end of the cross bar is connected to the other group of claws, and a hydraulic piston is connected between the two groups of claws.

[0006] The claw is formed by connecting two or three clamping claws into one body through a connecting seat.

[0007] The connecting seat is provided with connecting ears, and the connecting ears are connected to the hydraulic piston.

[0008] The rechargeable mobile hydraulic lift uses the FZPT0608D model to provide movement and a lifting platform.

[0009] The hammer-back clamp realizes the clamping function for the equipment, firmly holds the valve or pipe fitting, and prevents it from shaking left and right.

[0010] The utility model is a movable lifting and adjusting type, which can realize the fixed-point movement and lifting of pipe fittings and valves to the required installation positions, and has good control over the installation positions, heights, verticality and horizontality of pipe fittings and valves. More importantly, it ensures that valves or pipe fittings are not prone to slipping and displacement during transportation and installation.

[0011] The utility model is convenient to use and has precise control, which can greatly improve the safety and operability during the construction process, and comprehensively improve the project quality and project progress. Brief Description of the Drawings
