Technical Field

[0001] The utility model relates to the technical field of grouting pipes, in particular to a tool for drawing and injecting a high-polymer grouting pipe sleeve. Background Art

[0002] Grouting pipe, also known as jet pipe or perforating pipe, is a tool specially used for groundwater injection and grouting reinforcement. According to different materials, specifications and uses, there are many types of grouting pipes, such as conventional welded grouting pipes, steel flower pipes, small conduits, pipe roof pipes, plastic grouting pipes (including disposable grouting pipes, secondary grouting pipes, PE grouting pipes, etc.) and sleeve valve pipes (PVC grouting pipes).

[0003] During the foundation construction process, grouting pipes are often used in foundation reinforcement, pile foundation construction, and basement waterproofing. During foundation reinforcement, the grouting pipe can inject high-strength grouting materials into the foundation through grouting technology to fill the gaps and cracks in the foundation and improve the bearing capacity and stability of the foundation. Existing grouting pipes generally work by grouting vertically from top to bottom. However, in actual operation, due to site restrictions, such as in a trapezoidal structure foundation, it is necessary to grout inward along the outer wall of its inclined surface. At this time, the grouting pipe is in an inclined state, and the grouting pipe is prone to unstable position due to the influence of gravity, which affects the work of pulling out the grouting pipe. Therefore, the utility model proposes a high-polymer grouting pipe sleeve tooling for pulling out the above problems. Utility Model Content

When the device is in use, the base 1 is first erected on Above the grouting position, the sleeve 5 is sleeved on the outside of the grouting pipe, and then the fastening bolts 6 on the outside of the sleeve 5 are tightened. The grouting pipe is clamped with the fastening bolts 6, and the sleeve 5 and the grouting pipe are connected as one. The arm rod is inserted into the interior of the jack 3, and the jack 3 is used to drive the lifting frame 4 to move upward. The sleeve 5 is connected to the bottom end of the lifting frame 4 to drive the grouting pipe upward and pull it out from the foundation. The adjusting mechanism can adjust the angle of the jack 3 to match the angle of the inclined grouting pipe, which is conducive to a smoother process of pulling out the grouting pipe.

[0019] The adjusting mechanism includes a connecting rod 7, a rotating rod 8, a slide groove 9, a connecting bolt 10 and a fixing sleeve 11. The connecting rods 7 are symmetrically fixedly connected to both sides of the movable frame 2. A slide groove 9 is provided inside the base 1. The outer side of the connecting rod 7 is hinged with a rotating rod 8. The bottom end of the rotating rod 8 is fixedly connected with a connecting bolt 10. One end of the connecting bolt 10 passes through the inside of the slide groove 9 and is threadedly connected to the fixing sleeve 11. One end of the connecting rod 7 is hinged to one end of the base 1 through a rotating shaft 12.

[0020] One end of the fixing sleeve 11 extends into the interior of the sliding groove 9 , and the diameter of the other end of the fixing sleeve 11 is greater than the width of the sliding groove 9 .

[0021] The fixing sleeve 11 at the bottom end of the rotating rod 8 is loosened so that it no longer clamps the outer wall of the base 1, and the restriction between the rotating rod 8 and the slide groove 9 is released. The connecting bolt 10 at the bottom end of the rotating rod 8 can slide back and forth linearly inside the slide groove 9. The top end of the rotating rod 8 is hinged to the connecting rod 7, and the connecting rod 7 is connected to the movable frame 2 as a whole, so as to drive the movable frame 2 to rotate around the rotating axis 12, and the sleeve 5 and the jack 3 are fixed on the movable frame 2, and the position of the sleeve 5 and the jack 3 can be adjusted. Finally, the fixing sleeve 11 is tightened to lock their position so that it fits the angle of the inclined grouting pipe.

[0022] A through slot is provided on one side of the movable frame 2, and the sleeve 5 is vertically parallel to the through slot to avoid interference with the up and down movement of the grouting pipe.

[0023] A clamping plate is provided at the top of the lifting frame 4 and one side of the movable frame 2. The two clamping plates are parallel to each other and are connected to each other by a spring 13. The top and bottom ends of the spring 13 are respectively clamped inside the two clamping plates, and the lifting frame 4 and the movable frame 2 are connected to each other by the spring 13. The spring 13 cushions and absorbs vibration and impact by compression and extension, thereby reducing the impact force and load that the jack 3 may encounter during the lifting process, and protecting the jack 3 and the grouting pipe supported by it from damage.

[0024] One side of the movable frame 2 is symmetrically fixedly connected to a limit rod 14 , the outer wall of the limit rod 14 is fitted and connected to the outer wall of the bottom plate at the bottom of the jack 3 , and one side of the movable frame 2 is provided with a fixing mechanism matching the movable frame 2 .

[0026] Insert the jack 3 into the interior of the movable frame 2, and the outer wall of the base plate at the bottom of the jack 3 fits into the outer wall of the limit rod 14, and one side of the base plate also fits into one side of the movable frame 2. Turn the threaded rod 15 in the forward direction to drive the clamping block 16 to move toward the base plate, and clamp the base plate through the clamping block 16 to fix the jack 3 on the movable frame 2. When disassembling, just turn the threaded rod 15 in the reverse direction to drive the clamping block 16 away from the base plate, and the jack 3 can be pulled out from the movable frame 2.

[0027] The grouting pipe sleeve tooling loosens the fixed sleeve 11 at the bottom end of the rotating rod 8 so that it no longer clamps the outer wall of the base 1, thereby releasing the restriction between the rotating rod 8 and the slide groove 9. The connecting bolt 10 at the bottom end of the rotating rod 8 can slide back and forth in a straight line inside the slide groove 9. The top end of the rotating rod 8 is hinged to the connecting rod 7, and the connecting rod 7 is connected to the movable frame 2 as a whole, so as to drive the movable frame 2 to rotate around the rotating axis 12, and the sleeve 5 and the jack 3 are fixed on the movable frame 2, and the position of the sleeve 5 and the jack 3 can be adjusted. Finally, the fixed sleeve 11 is tightened to lock their position so that it fits the angle of the inclined grouting pipe, which is conducive to a smoother process of pulling out the grouting pipe.
