Description

Technical Field

[0001] The utility model relates to the technical field of water injection blocks for hollow grouting anchor rods, in particular to a water injection block for a high-pressure grouting pump of a hollow grouting anchor rod. Background Technique

[0002] A grouting anchor rod is an engineering material that combines the functions of anchoring and grouting. By driving the anchor rod into the internal part of the rock and soil mass, and using a high-pressure grouting pump to inject a special cement slurry or chemical slurry into the rock and soil mass around the anchor rod, a continuous reinforcement layer is formed to enhance the overall strength and stability of the rock and soil mass. The high-pressure grouting pump is an indispensable equipment in this process. It can evenly and quickly transport the slurry to the designated position under high pressure to ensure the grouting effect.

[0003] In the prior art, when the grouting pump works, it is necessary to mix raw materials with water, and the grouting pump is connected to the water pipe for mixing raw materials. Moreover, the mixing pipeline also needs to be connected to the external water pump pipeline to facilitate the mixing of raw materials and water. When connecting the external water pump and the mixing pipeline in the prior art, it is mainly through the connection of the external pipeline with the mixing pipeline and the water pump. Among them, when the water injection pipeline is connected to the mixing pipeline, a corresponding water injection block is required, so that the water injection block is bolted to the mixing pipeline. Then, water is injected from the wall of the mixing pipeline through the water injection block. However, after long-term use of the mixing pipeline, it is easy to block the water spraying holes opened on the wall of the mixing pipeline, affecting the entry of water flow, and further reducing the mixing efficiency of the slurry in the mixing pipeline, thus affecting the grouting work of the grouting pump. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a water injection block for a high-pressure grouting pump of a hollow grouting anchor rod, so as to solve the technical problems mentioned in the above background technique.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] The water passing component includes a support spring and a through rod. A through groove is formed in the middle of the water injection block body. The top side of the through groove is provided with a constricted opening. The through rod is slidably installed in the through groove. The bottom end of the through rod extends into the discharge pipeline. The top end of the support spring is fixedly connected to the inner top side wall of the through groove.

[0008] In a preferred example of the present utility model, it can be further configured that: a number of auxiliary grooves are formed on the side of the through groove in the water injection block body. The auxiliary grooves communicate with the through groove. The auxiliary grooves are L-shaped. A cavity tube is slidably connected to the bottom end inside the auxiliary groove. The bottom end of the cavity tube is closed. Water outlet holes are formed at the bottom of the outer peripheral side of the cavity tube. The top end of the cavity tube is fixedly connected with an auxiliary spring. The top end of the auxiliary spring extends upward and is fixedly connected to the inner side wall of the auxiliary groove.

[0009] In a preferred example of the present utility model, it can be further configured that: the bottom end of the through rod is arc-shaped, and the bottom end of the through rod is aligned with the inner side wall of the discharge pipeline.

[0013] 1. For this high-pressure grouting pump water injection block of the hollow grouting bolt, during use, the holes on the discharge pipeline can be blocked by the provided through rod and cavity tube. When injecting water, the through rod and cavity tube are inserted into the discharge pipeline, and then water can be introduced into the discharge pipeline through the drainage holes and water outlet holes, achieving the effect of blocking the holes on the discharge pipeline by the through rod and cavity tube, avoiding the holes being blocked by the grouting raw materials and thus affecting the water injection of the water pump.

[0014] 2. The water injection block of the high-pressure grouting pump for the hollow grouting bolt is arranged such that the water outlet holes face away from the through groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will further elaborate on the present invention in conjunction with the accompanying drawings.

[0022] Embodiment:

[0023] Referring to Figures 1 - 3, the water injection block of the high-pressure grouting pump for the hollow grouting bolt disclosed by the utility model includes a discharge pipeline 1. A positioning groove 2 is formed on the outer peripheral side of the discharge pipeline 1. A water injection block body 3 is arranged in the positioning groove 2. A pipeline joint 17 is fixedly connected to the top side of the water injection block body 3. A water passing component 4 is arranged in the water injection block body 3. A positioning component 5 is arranged on the side of the water injection block body 3;

[0024] The water passing component 4 includes a support spring 6 and a through rod 7. A through groove 8 is formed in the middle of the water injection block body 3. The top side of the through groove 8 is provided with a reduced opening. The through rod 7 is slidably installed in the through groove 8. The bottom end of the through rod 7 extends into the discharge pipeline 1. The top end of the support spring 6 is fixedly connected to the inner top side wall of the through groove 8. The bottom end of the support spring 6 is fixedly connected to the through rod 7. An empty groove 9 is formed at the top end of the through rod 7. Drainage holes 10 are formed at the bottom of the outer peripheral side of the through rod 7. The drainage holes 10 communicate with the empty groove 9. The outer peripheral side of the through rod 7 is in fit with the inner peripheral side of the through groove 8.

[0025] In this embodiment, when installing the water injection block body 3, the water injection block body 3 is inserted into the positioning groove 2 at this time and fixed by the positioning component 5. Subsequently, the arranged pipeline connector is connected to the water pipe of an external water pump. When the water pump injects water, it will be injected into the water injection block body 3 from the pipeline joint 17, and then enter the through groove 8, and then enter the empty groove 9 on the through rod 7. The bottom end of the through pipe is closed. At this time, the water flow cannot enter the discharge pipeline 1. As the water is injected, the water pressure will gradually increase, thereby pushing the through rod 7 to slide into the discharge pipeline 1, and gradually pushing the drainage holes 10 on the through rod 7 into the discharge pipeline 1. At this time, the drainage holes 10 will discharge the water flow into the discharge pipeline 1, thereby adding mixing water to the grouting raw material. At the same time, the arranged through rod 7 can block the holes on the discharge pipeline 1, avoiding the holes being blocked when mixing the grouting raw material in the discharge pipeline 1, thereby affecting the water injection.

[0026] In a further preferred embodiment of the utility model, as Figures 1 - 3 shown, a number of auxiliary grooves 11 are formed on the side of the through groove 8 in the water injection block body 3. The auxiliary grooves 11 communicate with the through groove 8. The auxiliary grooves 11 are L-shaped. A cavity pipe 12 is slidably connected to the bottom end in the auxiliary groove 11. The bottom end of the cavity pipe 12 is closed. Water outlet holes 13 are formed at the bottom of the outer peripheral side of the cavity pipe 12. An auxiliary spring 14 is fixedly connected to the top end of the cavity pipe 12. The top end of the auxiliary spring 14 extends upward and is fixedly connected to the inner side wall of the auxiliary groove 11.

[0027] In this embodiment, a number of auxiliary grooves 11 are provided. When the water pump is injecting water, in addition to the through groove 8, water will also enter the auxiliary grooves 11. The water flow will also push the provided cavity tube 12. Since the top end of the cavity tube 12 is connected to the auxiliary spring 14, when the water flow reaches a certain water pressure, the bottom end of the cavity tube 12 will be pushed into the discharge pipeline 1, and then the water outlet hole 13 will be pushed into the discharge pipeline 1. At this time, the cavity tube 12 will inject water into the discharge pipeline 1, increasing the range of water drainage of the water injection block, so as to quickly wet the grouting raw materials to the greatest extent and improve the efficiency of mixing the grouting raw materials;

[0028] It should be noted that the auxiliary grooves 11 and the through groove 8 respectively correspond to the holes on the pipeline, so that the bottom ends of the cavity tube 12 and the through rod 7 can block the corresponding holes on the discharge pipeline 1. When draining water, the bottom ends of the cavity tube 12 and the through rod 7 will enter the discharge pipeline 1 from the holes, and then can drain water through the corresponding drain holes 10 and water outlet holes 13.

[0029] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, the bottom end of the through rod 7 is arc-shaped, and the bottom end of the through rod 7 is aligned with the inner side wall of the discharge pipeline 1. The bottom end of the cavity tube 12 is aligned with the inner side wall of the discharge pipeline 1, and the bottom end of the cavity tube 12 is arc-shaped.

[0030] In this embodiment, the bottom ends of the provided through rod 7 and the cavity tube 12 are both arc-shaped, and the arc is corresponding to the inner side wall of the discharge pipeline 1. At the same time, the bottom ends of the cavity tube 12 and the through rod 7 are aligned with the inner side wall of the discharge pipeline 1. Thus, when cleaning the mixing pipeline, the inside of the discharge pipeline 1 can be directly cleaned as a whole, avoiding the need to clean the bottom ends of the through rod 7 and the cavity tube 12 twice. After the water injection is completed, the auxiliary spring 14 and the support spring 6 lose the pressure of water, and will respectively pull the corresponding cavity tube 12 and through rod 7 back into the through groove 8 and the auxiliary groove 11 by the reaction force. The grouting slurry adhered to the outer peripheral sides of the through rod 7 and the cavity tube 12 will be scraped off by the bottom of the side wall of the hole on the pipeline respectively, further avoiding the situation that the holes on the discharge pipeline 1 are blocked.

[0031] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, the orientation of the water outlet hole 13 is away from the through groove 8, and the outer peripheral side of the cavity tube 12 fits with the inner peripheral side of the auxiliary groove 11.

[0032] In this embodiment, the water outlet hole 13 is set to face away from the through groove 8, so that when the water at the water outlet hole 13 is discharged, it can be discharged to the surroundings in the discharge pipeline 1. While flushing the side wall of the discharge pipeline 1, the water injection range is expanded, and then the slurry raw materials can be quickly wetted and mixed, improving the mixing efficiency and avoiding the raw materials from sticking to the inner side wall of the discharge pipeline 1.

[0033] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, the positioning member 5 includes a positioning disk 15, a screw hole 16 is formed on the discharge pipeline 1, and the positioning disk 15 is bolted to the outer peripheral side of the discharge pipeline 1 through the screw hole 16.

[0034] In this embodiment, in the provided positioning member 5, after the water injection block 3 is inserted into the positioning groove 2, the top side of the positioning disk 15 will fit against the outer peripheral side of the discharge pipeline 1, and the positioning disk 15 can be fixed at the screw hole 16 by bolts, achieving the effect of positioning the water injection block 3.

[0035] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
