Problems solved by technology

[0007] This method is the easiest but the efficiency is low. First, it is necessary to manually wrap the steel wire rope from the bottom of the pipe and lock the pipe joint with a lock. After the pipe is installed in place, it is necessary to manually climb to the back of the pipe to release the lock, which is inefficient and dangerous. 2. When the crane pulls out the wire rope, it is easy to drag the pipeline, which will cause the lateral displacement of the installed pipeline and cause the installation to fail; when the pipeline is displaced, it will easily squeeze the workers, and the safety is poor

Embodiment 1

[0040] like figure 1 and figure 2As shown, a tongue and groove pipe hoisting fixture includes a hanger body 10. The hanger body 10 is provided with two hangers and the tops of the two are connected by opening and closing shafts to achieve the effect of opposite movement directions. The inner side of the hanger body 10 is installed with a The mouth tube protection structure 20, the tongue and groove tube protection structure 20 is a flexible rubber strip, and the clamp also includes a locking structure installed between the tops of the two hanger bodies 10, which is locked when the hanger body 10 lifts the tongue and neck tube. The structure locks the hanger body 10 in a stable state. The locking structure includes a positioning hole 11 disposed on the top of the hanger body 10 , and a limit pin 12 installed in the two corresponding positioning holes 11 . When hoisting the groove and mouth pipe, first open the two hanger bodies 10, then close the two hanger bodies 10 to the ...

Embodiment 2

[0042] like image 3 and Figure 4 As shown, the difference from the locking structure in Embodiment 1 is that the two hanger bodies can also achieve the opposite effect of the moving direction through the locking structure. The sliding block 31 connected with the hook of the hoisting equipment, the guide roller 32 is installed on the mounting frame 30 under the sliding block 31, and the bottom of the sliding block 31 is rotatably installed with the guide blocks 33 which are fixedly installed with the corresponding hanger body 10 respectively. A limiting structure 38 is installed on the frame 30, the top of the slider 31 is rotated and installed with a stepped shaft 34 whose diameter gradually increases from bottom to top, and the top of the stepped shaft 34 is connected with the hook of the hoisting equipment, and the mounting frame 30 located above the slider 31 The upper part is provided with a limit hole 35 adapted to the large diameter of the stepped shaft 34 and a guide...

Embodiment 3

[0051] like Figure 5 and Image 6 As shown, the locking structure is different from the above-mentioned embodiment, and the two hanger bodies can also achieve the opposite effect of the movement direction through the locking structure. Two connecting rods 41 are provided, the two connecting rods 41 can slide left and right relative to the hoisting main body 40, and the free ends of the two connecting rods 41 are jointly rotatably connected with a hoisting auxiliary body 42 connected with the hook of the hoisting equipment. A connecting rod 43, which is rotatably installed with the corresponding hanger body 10, is rotatably installed at the rotating node of the body 42 and the connecting rod one 41. The top of the hoisting sub-body 42 is installed with a stepped shaft 34 whose diameter gradually increases from bottom to top. The top of 34 is connected with the hook of the hoisting equipment, and the hoisting auxiliary body 42 located above the hoisting auxiliary body 42 is pr...

Abstract

The invention discloses a tongue-and-groove pipe hoisting clamp and a hoisting method.The tongue-and-groove pipe hoisting clamp comprises two hoisting frame bodies, the tops of the two hoisting frame bodies are connected through an opening and closing shaft, tongue-and-groove pipe protection structures are installed on the inner sides of the hoisting frame bodies, and the clamp further comprises a locking structure installed between the tops of the two hoisting frame bodies; when the hanging bracket bodies hoist the tongue-and-groove pipe, the locking structures lock the hanging bracket bodies and enable the hanging bracket bodies to be in a stable state, when the tongue-and-groove pipe is hoisted, the two hanging bracket bodies are firstly opened, then the two hanging bracket bodies are tightly closed towards the middle and are locked after being matched with the positioning holes through the limiting pins, and at the moment, the closing action of the bottoms of the two hanging bracket bodies is completed; the tongue-and-groove pipe is safely hoisted to a preset position through hoisting equipment, and the existing technical problems are effectively solved.

Description

technical field [0001] The invention belongs to the field of municipal pipeline installation, and particularly relates to a tongue and groove pipe hoisting fixture and a hoisting method. Background technique [0002] Concrete pipes are widely used as one of the main materials for drainage projects. The factory length of concrete pipes is limited (usually 2 meters), but the laying of pipes in the design is long-distance, so the length of pipes is often not enough during construction. The case of hoisting and assembling extension pipes. Concrete pipes are heavy and cannot be installed in place by manual movement. Usually, the following methods are used to install concrete pipes: [0003] 1. Using the steel wire rope as the spreader, the concrete pipe is centered along the length direction, and the steel wire rope is used to wrap it in the circumferential direction, and the lock is used to lock the pipe section. [0004] 2. Lift the other end of the wire rope with a crane and...
