Specific embodiments

[0024] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Embodiment:

[0026] Referring to Figures 1 - 5 , the high-pressure grouting pump suspension structure of the hollow grouting bolt disclosed by the present utility model includes a discharge main pipe 1 and a pump unit 2. A first positioning ring 3 is fixedly connected to the outer peripheral side of the end of the discharge main pipe 1, and a second positioning ring 4 is fixedly connected to the outer peripheral side of the input end of the pump unit 2. A clamping member 5 and a load-bearing member 6 are respectively arranged between the first positioning ring 3 and the second positioning ring 4;

[0027] The clamping member 5 includes a positioning plate 7, a rotating plate 8, a positioning block 9, a spring 10, a pull rod 11 and a clamping rod 12. The positioning plate 7 is fixedly installed on the outer peripheral side of the second positioning ring 4. A groove 13 is opened on the side of the positioning plate 7. The rotating plate 8 is rotatably installed in the groove 13. A through groove 14 is opened at the end of the rotating plate 8. The positioning block 9 is arranged in the through groove 14. The end of the spring 10 is fixedly connected to the surface side of the positioning block 9. The pull rod 11 is slidably installed in the groove 13, and the end of the pull rod 11 is fixedly connected to the spring 10. The clamping rod 12 is fixedly installed at one end of the pull rod 11 away from the positioning plate 7. The clamping rod 12 is L-shaped. A clamping groove 15 corresponding to the clamping rod 12 is opened on the surface side of the first positioning ring 3. The end of the clamping rod 12 is inserted into the clamping groove 15.

[0028] In this embodiment, when in use, first rotate the rotating plate 8 so that the end of the rotating plate 8 faces away from the second positioning ring 4. Then directly move the input end of the pump unit 2 to the discharge main pipe 1 and support it through the load-bearing member 6. While supporting through the load-bearing member 6, align and fit the input end of the pump unit 2 with the output end of the discharge main pipe 1. After that, rotate the rotating plate 8 and pull the clamping rod 12. The clamping rod 12 will drive the pull rod 11 to be pulled out, and the spring 10 will be stretched. Then release the clamping rod 12, and the clamping rod 12 will retract due to the reaction force of the spring 10. The reaction force of the spring 10 will pull the end of the clamping rod 12 into the card slot 15, so as to achieve the clamping connection between the first positioning ring 3 and the second positioning ring 4, achieving the effect of not needing to use bolts for connection and quickly docking and connecting the input end of the pump unit 2 and the discharge main pipe 1.

[0029] In a further preferred embodiment of the present utility model, as Figures 2 - 4 shown, an adjusting rod 16 is provided at the end of the clamping rod 12 on the side away from the positioning plate 7.

The adjusting rod 16 is rotatably connected to both the pull rod 11 and the clamping rod 12.

[0030] In this embodiment, the provided adjusting rod 16 can, after the first positioning ring 3 and the second positioning ring 4 are butted, rotate the adjusting rod 16 at this time, thereby driving the positioning block 9 to move towards the end side wall of the through groove 14, thereby stretching the spring 10, so as to increase the force of the clamping rod 12 being inserted into the card slot 15, avoiding the shaking of the clamping rod 12 caused by external vibration, and further preventing the clamping rod 12 from falling off the card slot 15 and affecting the connection between the input end of the pump unit 2 and the discharge main pipe 1.

[0031] In a further preferred embodiment of the present utility model, as Figures 2 - 4 shown, a pull ring 17 is fixedly connected to the outer peripheral side of the end of the adjusting rod 16 away from the positioning plate 7.

[0032] In this embodiment, the provided pull ring 17 is used to facilitate the rotation of the adjusting rod 16, so that the adjusting rod 16 can drive the positioning block 9 to slide in the through groove 14, and further control the stretching force of the spring 10 after the first positioning ring 3 and the second positioning ring 4 are butted, and further facilitate the control of the docking of the pump unit 2 and the discharge main pipe 1.

[0033] In a further preferred embodiment of the present utility model, as Figures 1 - 4As shown, the load-bearing member 6 includes a clamping cover 18.

Positioning holes 22 corresponding to the first positioning post 19 and the second positioning post 20 are respectively formed at the end portions of the two support rods 21.

[0034] In this embodiment, the provided clamping cover 18 is used for fixedly connecting with the outer peripheral side of the provided first positioning ring 3. When the pump unit 2 is lifted, the positioning holes 22 on the two support rods 21 are respectively aligned with the first positioning post 19 and the second positioning post 20, and then lowered, so that the support rods cooperate with the first positioning post 19, the second positioning post 20 and the clamping cover 18 to hold the pump unit 2, thus eliminating the need to hold the pump unit 2 manually for a long time, and further reducing physical exertion.

[0035] In a further preferred embodiment of the present utility model, as Figure 5 shown, sealing rings 23 are fixedly connected to both the input end of the pump unit 2 and the output end of the discharge main pipe 1. The input end of the pump unit 2 is in mutual fit with the output end of the discharge main pipe 1.

[0036] In this embodiment, the two provided sealing rings 23 enable the end portions of the pump unit 2 and the discharge main pipe 1 to be in fit, thereby ensuring the sealing property between the two after the input end of the pump unit 2 is docked with the output end of the discharge main pipe 1.

[0037] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the opposite side surfaces of the first positioning ring 3 and the second positioning ring 4 are in mutual fit.
