Description

Technical Field

[0001] The utility model relates to the technical field of coal mine tunnel support grouting, in particular to a grouting device. Background Art

[0002] Coal mine tunnel support grouting is an engineering technology that injects specific materials (usually slurry or liquid concrete) into rock cracks, tunnel walls or cavities. The main purpose of this technology is to enhance the stability and bearing capacity of the tunnel and prevent problems such as collapse or landslides caused by unstable geological conditions. During the grouting operation, due to the geological environment in the tunnel, it is usually necessary to use grouting fluid (concrete slurry) and filling fluid (such as high-flowability polyurethane filler) for support grouting operations. The grouting fluid is used to fill and reinforce cracks and voids in the rock formation to prevent the risk of tunnel structure instability or rock collapse caused by rock cracks, and to fill and level the irregular space inside the tunnel to improve the overall flatness and reduce the voids in the tunnel. When the existing device replaces the grouting material for grouting operation, the new filler may be mixed with the residual filler in the pipeline because the existing device cannot thoroughly clean the residual filler in the pipeline. This mixing may affect the reliability of the grouting operation because the two different fillers may be different in properties and curing characteristics, resulting in the final grouting effect being unstable or not meeting the design requirements.

[0003] The implementation of the utility model aims to provide a grouting device to solve the problems raised in the above background technology. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example

[0029] Reference Figure 1-7 A grouting device includes a storage box 2, a joint 5, and a plug 6. The storage box 2 is embedded in the upper right side of the bottom base 1, and the mud pump is embedded in the upper left side of the bottom base 1. A protective box is arranged on the outside of the mud pump, and the output end of the mud pump is arranged on the left side and is connected with the grouting head 3. The input end of the mud pump is arranged on the right side and is connected with the connecting pipe 4.

[0030] One side of the storage box 2 is embedded with a plug 6, and the other end of the plug 6 is embedded with a joint 5, the other end of the joint 5 is embedded with a connecting pipe 4, the other end of the connecting pipe 4 is connected to a mud pump, and the other end of the mud pump is embedded with a grouting head 3. The inner side of the storage box 2 is embedded with a water tank 201, and the upper end of the water tank 201 is located inside the storage box 2 and is fixedly connected with a partition 202. The storage box 2 divides the internal space into two storage chambers by the partition 202. The two storage chambers can be used to store filling liquid and grouting liquid respectively. The water tank 201 located at the lower end of the storage box 2 is used to store cleaning water. When the staff needs to replace the output material of the grouting head 3, the staff can connect the joint 5 to the plug 6 on the outside of the water tank 201, and then use the mud pump to draw the cleaning water in the water tank 201 to flush out the filling material remaining in the pipeline and the grouting head 3, so as to avoid the replacement of the output filling material and the mixing of the replaced filling material with the filling material remaining in the pipeline.

[0031] The outer sides of the connector 5 and the plug 6 are interlocked with a reinforcement sleeve 7, and the outer side of the reinforcement sleeve 7 is interlocked with a fixing buckle 8, one end of the plug 6 is fixedly connected with a plug fixing ring 11, and the outer side of the plug fixing ring 11 is interlocked with a fixing groove 9, the outer side of the connector 5 is interlocked with a movable sleeve 12, and one end of the connector 5 is fixedly connected with a connector fixing ring 13, and the surface of the connector fixing ring 13 is interlocked with the fixing groove 9. Through this design, when connecting the connector 5 and the plug 6, the staff can directly insert the connector 5 into the inside of the plug 6, and then put the reinforcement sleeve 7 on the connection between the connector 5 and the plug 6 and fix it by the fixing buckle 8, thereby simplifying the connection process of the connector 5 and the plug 6.

[0032] The connector 5 as a whole is composed of a hollow cylindrical connector body and a circular ring-shaped limit ring on the outside of the connector body, the movable sleeve 12 is embedded in the outside of the connector body, and the movable sleeve 12 as a whole is composed of an operating ring and a sleeve on the outside of the operating ring, the inner surface of the plug 6 is embedded with a card plate 15, and one side of the card plate 15 is located inside the plug 6 and is embedded with 16. Through this design, when the connector 5 is inserted into the plug 6, the limit ring on one side of the connector 5 will squeeze the card plate 15 inside the plug 6, so that the card plate 15 retracts inward through the inner 16, and then when the card groove 14 on one side of the limit ring moves to the outside of the card plate 15, due to the card groove 14 The diameter is smaller than the diameter of the limiting ring, so that the card plate 15 loses the squeezing of the limiting ring and rebounds under the action of 16, so that the card plate 15 is stuck on the outside of the card slot 14, thereby completing the connection between the connector 5 and the plug 6. When the connector 5 needs to be taken out from the inside of the plug 6, the staff can push the movable sleeve 12 to one side of the plug 6 so that the movable sleeve 12 covers the surface of the card slot 14. During the movement of the movable sleeve 12, the movable sleeve 12 will squeeze the card plate 15, so that the card plate 15 retracts to the inner side of the plug 6, thereby making the card plate 15 lose its limiting effect on the connector 5, and then the staff can directly take the connector 5 out from the inside of the plug 6.

[0033] The interior of the reinforcement sleeve 7 is provided with two sets of parallel fixed plates 10 corresponding to the fixed grooves 9 on the surfaces of the plug fixing ring 11 and the connector fixing ring 13. Through this design, when the reinforcement sleeve 7 is sleeved on the outside of the connector 5 and the plug 6, the fixed plates 10 inside the reinforcement sleeve 7 can be respectively inserted into the fixed grooves 9 on the surfaces of the plug fixing ring 11 and the connector fixing ring 13, so that the reinforcement sleeve 7 can reinforce the connection stability between the connector 5 and the plug 6 through the fixed plates 10. At the same time, the reinforcement sleeve 7 can prevent external dust and other impurities from entering the surface of the movable sleeve 12 and the clamping groove 14, thereby preventing dust from affecting the normal sliding of the movable sleeve 12 on the surface of the clamping groove 14.

[0034] The whole material of the reinforcement sleeve 7 is rubber, and the outer surface of the reinforcement sleeve 7 is provided with anti-skid patterns. Through this design, the anti-skid patterns can enhance the friction between the reinforcement sleeve 7 and the palm of the staff, so that the staff can better grasp the reinforcement sleeve 7.

[0035] The fixing buckle 8 as a whole is composed of a connecting end fixed at one end of the reinforcement sleeve 7 and a fixed end located at the other end of the reinforcement sleeve 7. The reinforcement sleeve 7 as a whole is in the shape of a circular ring with an opening on the side, and the reinforcement sleeve 7 is divided into two ends by this opening. Through this design, when the staff fixes the reinforcement sleeve 7 on the surface of the connector 5 and the plug 6, the connecting end of the fixing buckle 8 can be removed from the fixed end surface, and then the reinforcement sleeve 7 can be put on the surface of the connector 5 and the plug 6. In this process, since the side of the reinforcement sleeve 7 has an opening, the staff can pry open the reinforcement sleeve 7 so that the reinforcement sleeve 7 can be put on the surface of the connector 5 and the plug 6 more quickly. Then the staff can clamp the connecting end of the fixing buckle 8 on the fixed end surface to fix the reinforcement sleeve 7 on the surface of the connector 5 and the plug 6.

[0036] It should be noted that the connecting end of the fixing buckle 8 is a rubber strip with a plurality of holes on its surface, and the fixed end is a rubber clamping rod with a plurality of protrusions on its surface. The clamping rod is composed of a round rod connected at the bottom and a hemispherical round head at the upper end of the round rod. When the connecting end is sleeved on the surface of the fixed end, the holes are inserted into the outside of the round rod through the hemispherical round head. Then, due to the overall characteristics of the hemispherical round head with a small diameter at the upper end and a large diameter at the bottom, the connecting end is clamped at the round rod.

[0037] Working principle: When the device is in operation, the filler inside the storage box 2 can be extracted by a mud pump and output through the grouting head 3 for grouting operation. When the staff needs to replace the output material of the grouting head 3, the staff can connect the joint 5 with the plug 6 on the outside of the water tank 201, and then use the mud pump to extract the clean water in the water tank 201 to flush out the filler remaining in the pipeline and the grouting head 3, so as to avoid the replacement of the output filler and the filling material remaining in the pipeline. Mixing.

[0038] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0039] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
