DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 5 The portable drilling and rotating grouting integrated joint disclosed in the utility model comprises a grouting sealing cylinder 1, a through hole 4 is opened at the end thereof, a grouting joint 5 for connecting a grouting pipe is fixedly connected to the outer peripheral side, and a grouting groove 6 connected to the grouting joint 5 is formed in the middle of the through hole 4;

[0028] Drilling a grouting screw rod 2, which is inserted into the through hole 4 and is rotatably connected to the grouting sealing cylinder 1;

[0029] An anti-slip assembly 3 is arranged at the opening of the through hole 4 and is rotatably connected to the drilling and grouting screw rod 2;

[0030] The drilling and grouting spiral rod 2 includes a drilling rig clamping handle 21, a hand handle 22, a grouting sealing rod 23 and a drill sleeve connector 24. The two ends of the hand handle 22 are respectively provided with a drilling rig clamping handle 21 and a grouting sealing rod 23. The end of the grouting sealing rod 23 away from the hand handle 22 is fixedly connected to the drill sleeve connector 24. The end of the drill sleeve connector 24 is provided with a grouting channel 7 extending to the middle of the grouting sealing rod 23. The outer side wall of the grouting sealing rod 23 is located on one side of the grouting groove 6 and is provided with a grouting hole 8 connected to the grouting channel 7.

[0031] In this embodiment, since it is necessary to first connect the drill rod with the drill sleeve, and then connect the drill sleeve with the anchor rod to drill the anchor point, the process of anchor construction will be increased, affecting the efficiency of anchor construction. Figure 1 and Figure 2 It can be found that a through hole 4 is opened at the end of the grouting sealing tube 1, so that the drilling and grouting screw rod 2 can be inserted into the through hole 4 of the grouting sealing tube 1, and the end of the drilling and grouting screw rod 2 exposed on the outside of the grouting sealing tube 1 is provided with a drilling rig clamping handle 21 and a drill sleeve connector 24, so that the two ends of the drilling and grouting screw rod 2 can be connected to a turntable and a drill sleeve respectively, so that the drilling and grouting screw rod 2 can drill holes at the anchoring point under the drive of the drilling rig.

[0032] And observe Figure 3 It can be found that a grouting joint 5 is provided on the outer wall of the grouting sealing tube 1, a grouting groove 6 connected with the grouting joint 5 is opened in the through hole 4, and a grouting hole 8 is opened on the outer side wall of the grouting sealing rod 23 of the drilling and grouting screw rod 2 located in the through hole 4, and then a grouting channel 7 connected with the grouting hole 8 is provided at the end of the drill sleeve connector 24, so that the slurry water can enter the grouting groove 6 through the grouting joint 5, and then enter the grouting channel 7 along the grouting hole 8 of the grouting sealing rod 23, and finally be discharged through the grouting channel 7, so that the drilling rig drives the drilling and grouting screw rod 2 to perform drilling and grouting operations on the anchor point at the same time, saving engineering time.

[0033] The portable drilling and grouting integrated joint will be pressed down during the drilling process, and since the grouting sealing cylinder 1 and the drilling and grouting spiral rod 2 are not fixed, the drilling and grouting spiral rod 2 will be separated from the grouting sealing cylinder 1 during the drilling process, affecting the use of the portable drilling and grouting integrated joint. Figure 2It can be found that an anti-slip assembly 3 is connected to one side of the drilling and grouting screw rod 2 where the drill sleeve connector 24 is provided. The anti-slip assembly 3 is used to limit the drilling and grouting screw rod 2 to prevent the drilling and grouting screw rod 2 from separating from the grouting sealing tube 1, thereby making the operation of the portable drilling and rotating grouting integrated joint more stable.

[0034] In a further preferred embodiment of the present invention, Figure 2 As shown, the hand-held handle 22 is located at the intersection of the drill clamping handle 21 and the grouting sealing rod 23 and is protruded to form an annular portion 9 for limiting, and the diameter of the annular portion 9 located at the grouting sealing rod 23 is larger than the diameter of the through hole 4.

[0035] In this embodiment, by providing a hand-held handle 22 in the drilling and grouting screw rod 2, the drilling and grouting screw rod 2 can be more convenient to install. By providing annular portions 9 for limiting on both sides of the hand-held handle 22, and making the diameter of the annular portion 9 close to the grouting sealing rod 23 larger than the diameter of the through hole 4, the drilling and grouting screw rod 2 can be limited when connected to the grouting sealing tube 1, thereby limiting the insertion depth of the grouting sealing rod 23 and, at the same time, limiting the length of the drilling rig clamping handle 21, thereby making the installation of the drilling grouting screw rod 2 more convenient.

[0036] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the diameter of the grouting sealing rod 23 is the same as the diameter of the through hole 4 , and the inner sidewalls of the through hole 4 are located on both sides of the grouting groove 6 and are provided with sealing rings 10 in contact with the grouting sealing rod 23 .

[0037] In this embodiment, since the grouting sealing rod 23 of the drilling grouting spiral rod 2 and the through hole 4 of the grouting sealing cylinder 1 can rotate, there is a gap between the grouting sealing rod 23 and the through hole 4, which will cause slurry leakage and affect the use of the portable drilling rotary grouting integrated joint. Therefore, in order to reduce the existence of the gap, the diameter of the grouting sealing rod 23 is made the same as the diameter of the through hole 4. However, due to the existence of assembly tolerance, a small gap will still be generated between the grouting sealing rod 23 and the through hole 4, so it is observed that Figure 3 and Figure 4 It can be found that sealing rings 10 are arranged on both sides of the through hole 4 located in the grouting groove 6, and the grouting sealing rod 23 is in contact with the sealing ring 10 when inserted into the through hole 4. The sealing ring 10 is used to reduce the gap between the grouting sealing rod 23 and the through hole 4, which can improve the sealing effect and avoid slurry leakage, thereby improving the practicality of the portable drilling and rotating grouting integrated joint.

[0038] In a further preferred embodiment of the present invention, Figure 2 and Figure 5As shown, the anti-slip assembly 3 includes a limiting ring 31, a sleeve 32 and a retaining spring 33. The outer wall of the grouting sealing rod 23 on one side close to the drill sleeve connector 24 is provided with an annular groove 11 and is clamped with a retaining spring 33. The retaining spring 33 is provided with a sleeve 32 on the side close to the grouting sealing tube 1. The inner side wall of the sleeve 32 is rotatably connected to the limiting ring 31 through a bearing. The side of the limiting ring 31 away from the sleeve 32 is in contact with the end of the grouting sealing tube 1.

[0039] In this embodiment, since the drilling and grouting screw rod 2 is not fixed to the through hole 4 of the grouting sealing tube 1, in order to prevent the drilling and grouting screw rod 2 from separating from the grouting sealing tube 1 during the drilling process, an annular groove 11 is opened on the grouting sealing rod 23 of the drilling and grouting screw rod 2, and a retaining spring 33 is clamped in the annular groove 11, and the retaining spring 33 is used to prevent the drilling and grouting screw rod 2 from separating from the grouting sealing tube 1.

[0040] Since the drilling and grouting screw rod 2 rotates at high speed during drilling, the retaining spring 33 and the grouting sealing tube 1 rub rapidly, causing wear of the retaining spring 33 and the grouting sealing tube 1, affecting the stability of the portable drilling and rotating grouting integrated joint. Figure 2 It can be found that a shaft sleeve 32 is provided on the side of the retaining ring 33 close to the grouting sealing tube 1, and at the same time, a limiting ring 31 is connected to the shaft sleeve 32 through a bearing. The limiting ring 31 is in contact with the grouting sealing tube 1, so that when the drilling and grouting screw rod 2 rotates at a high speed, the friction is reduced by the high-speed rotation of the bearing, thereby reducing the damage caused to the portable drilling and rotating grouting integrated joint during use, and can effectively improve the service life of the portable drilling and rotating grouting integrated joint.

[0041] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, a plurality of protruding limiting portions 12 are provided in an annular array on one side of the limiting ring 31 away from the shaft sleeve 32 , and limiting grooves 13 for inserting the limiting portions 12 are provided at both end portions of the grouting sealing tube 1 .

[0042] In this embodiment, a limiting portion 12 is provided on the outer wall of the limiting ring 31, and a limiting groove 13 for inserting the limiting portion 12 is opened on the outer wall of the grouting sealing tube 1, which can facilitate the installation of the anti-detachment component 3, make the assembly of the portable drilling and rotating grouting integrated joint more convenient, improve the installation efficiency of the portable drilling and rotating grouting integrated joint, and thus improve the efficiency of the anchoring construction.

[0043] By providing limiting grooves 13 on both sides of the grouting sealing tube 1, the anti-detachment component 3 can be installed arbitrarily on both sides of the grouting sealing tube 1, so that the drilling and grouting spiral rod 2 can be installed with the grouting sealing tube 1 in any direction, further reducing the assembly difficulty of the portable drilling and rotating grouting integrated joint.

[0044] In a further preferred embodiment of the present invention, Figure 1 As shown, the outer side wall of the grouting sealing tube 1 is fixedly connected with reinforcing ribs 14 on both sides of the grouting joint 5 , and the side of the grouting sealing tube 1 away from the grouting joint 5 is fixedly connected with a handle 15 .

[0045] In this embodiment, since a pipeline for conveying slurry water needs to be reserved in the grouting joint 5, the strength of the grouting joint 5 is weakened. Therefore, reinforcing ribs 14 for supporting the grouting joint 5 are provided on the outside of the grouting sealing tube 1, which can effectively improve the service life of the portable drilling and rotating grouting integrated joint.

[0046] By providing a handle 15 on the outer wall of the grouting sealing tube 1, the portable drilling and rotating grouting integrated joint can be more convenient to take during use, making the use of the portable drilling and rotating grouting integrated joint more convenient and further improving the practicality of the portable drilling and rotating grouting integrated joint.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
