[0025] Please also read Figure 1 , Figure 2 and Figure 4 Now, the tube pulling device for the wall protection tube provided by the utility model is described. The tube pulling device for the wall protection tube includes a power unit and a tube pulling unit. The power unit includes a lifting member 11 that can be lifted and lowered and a driving assembly 12 for driving the lifting member 11 to lift and lower. The tube pulling unit includes a horizontally arranged tube pulling shaft 21, which is connected to the lifting member 11 and is used to slide into the tube wall of the wall protection tube 3.

[0026] Compared with the prior art, the tube pulling device for the wall protection tube provided by the utility model slides the tube pulling shaft 21 into the tube wall of the wall protection tube 3, and then the driving component 12 drives the lifting member 11 to rise, and the tube pulling shaft 21 connected to the lifting member 11 will drive the wall protection tube 3 to move upward until the wall protection tube 3 is pulled out from the grouting hole, thereby avoiding the problem that it is more laborious to pull the wall protection tube 3 out of the grouting hole due to the lack of tube pulling devices for wall protection tubes on the market.

[0027] In this embodiment, a penetration hole 31 for the pipe pulling shaft 21 to penetrate is provided on the upper part of the pipe wall of the wall protection pipe 3. When the wall protection pipe 3 is penetrated into the grouting hole, the penetration hole 31 is located above the ground so that the pipe pulling shaft 21 can penetrate into the pipe wall of the wall protection pipe 3 through the penetration hole 31.

[0028] In some embodiments, the above-mentioned characteristic power unit can be used as follows Figure 1 See the structure shown. Figure 1 The power unit further includes a bottom plate 13 and a guide shaft 14. The bottom plate 13 is horizontally arranged. There are at least two guide shafts 14, which are vertically arranged and fixed on the bottom plate 13. The guide shafts 14 slide through the lifting member 11, so that the lifting member 11 can slide and rise.

[0029] In some embodiments, the feature drive component 12 may be implemented as follows: Figure 1 See the structure shown. Figure 1 The driving assembly 12 adopts a hydraulic cylinder or a pneumatic cylinder, the cylinder body of the driving assembly 12 is fixed on the bottom plate 13, and the piston rod of the driving assembly 12 can be extended and retracted in the vertical direction and is fixedly connected to the lifting member 11. The extension and retraction of the piston rod of the driving assembly 12 in the vertical direction can realize the lifting and retraction of the lifting member 11.

[0030] In some embodiments, see Figure 1 The number of the power units is two, and the two power units are used to be symmetrically arranged on both sides of the wall protection pipe 3. When the wall protection pipe 3 is pulled out from the grouting hole, a greater power can be provided by the driving components 12 in the two power units.

[0031] In some embodiments, the above-mentioned characteristic power unit can be used as follows Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The power unit further includes two rolling wheels 15. The two rolling wheels 15 are arranged on the bottom plate 13. The two power units have a total of four rolling wheels 15, and the device can be conveniently driven to move by the support of the four rolling wheels 15. In this embodiment, the connection line between the four rolling wheels 15 is arranged in a rectangular shape.

[0032] In some embodiments, see Figure 2The number of the tube pulling units is two, and the two tube pulling units are symmetrically arranged on both sides of the wall protection pipe 3. The two tube pulling shafts 21 can share the force when the wall protection pipe 3 is pulled out from the grouting hole, thereby avoiding deformation of the tube pulling shafts 21.

[0033] In some embodiments, the above-mentioned characteristic extubation unit can be used as follows Figure 2 See the structure shown. Figure 2 The tube pulling unit is located between the two power units, and the tube pulling unit also includes a connecting member 22. The connecting member 22 is fixedly connected to both lifting members 11, and the connecting member 22 is slidably sleeved on the tube pulling shaft 21. The tube pulling shaft 21 is connected to the lifting member 11 through the connecting member 22.

[0034] In some embodiments, see Figure 2 The side wall of the tube-pulling shaft 21 has a stopper 211 protruding outward, and the stopper 211 is located between the connecting piece 22 and the wall-protecting tube 3. The tube-pulling unit also includes a compression spring 23. The compression spring 23 is sleeved on the tube-pulling shaft 21, and the two ends of the compression spring 23 are respectively in contact with the stopper 211 and the connecting piece 22. The resilience of the compression spring 23 can increase the resistance of the tube-pulling shaft 21 to slide out of the wall-protecting tube 3.

[0035] In some embodiments, the above-mentioned characteristic extubation unit can be used as follows Figure 2 See the structure shown. Figure 2 The tube extraction unit further includes a pull ring 24. The pull ring 24 is fixed on the tube extraction shaft 21, and is located on the side of the connecting member 22 away from the limiting portion 211. It is relatively labor-saving to slide the tube extraction shaft 21 out of the wall protection tube 3 by pulling the pull ring 24. At the same time, when the device is idle, the pull ring 24 can prevent the tube extraction shaft 21 from sliding off the connecting member 22 under the action of the rebound force of the compression spring 23.

[0036] In some embodiments, the above-mentioned characteristic power unit can be used as follows Figure 1 See the structure shown. Figure 1 The power unit further comprises a fixing member 16. The fixing member 16 is located above the guide shaft 14, and the fixing member 16 is fixedly connected to all guide shafts 14 in the same power unit. In this way, the guide shaft 14 can be prevented from bending and deforming to a certain extent.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
