The hole injection apparatus 100 according to the embodiment of the present invention will be described with reference to the accompanying drawings.

A hole grouting apparatus 100 according to an embodiment of the present invention, as shown in fig. 1 and 3, includes: the grouting device comprises an execution seat 1, a grouting pipe 2, a grouting piece 3 and an elastic piece 4.

As shown in fig. 3, the grouting pipe 2 is mounted on the actuator block 1.

As shown in fig. 3, the grouting member 3 is installed at the end of the grouting pipe 2, and the grouting member 3 includes a connecting cylinder 31 at the middle and a blocking plate 32 at the outer periphery, and the blocking plate 32 can cover the hole of the construction surface. Here, the area of the blocking plate 32 is larger than the area of the hole on the construction surface, so as to ensure that the blocking plate 32 can cover the hole on the construction surface.

As shown in fig. 3 and 4, the connecting cylinder 31 is provided with a feed port 311 communicating with the grout pipe 2, and the blocking plate 32 is provided with a pressure relief port 321 penetrating in the thickness direction.

As shown in fig. 3, the elastic element 4 is located between the actuator seat 1 and the closure plate 32.

As can be seen from the above structure, in the hole grouting device 100 according to the embodiment of the present invention, the grouting pipe 2 is mounted on the execution seat 1, and the execution seat 1 mainly plays a role of supporting the grouting pipe 2, so that the grouting pipe 2 is stable in position, and the transportation of the slurry can be completed.

Slip casting 3 is installed at the tip of slip casting 2, and slip casting 2 can be carried the thick liquids to the connecting cylinder 31 of slip casting 3 in, because of being equipped with the sprue 311 that communicates slip casting 2 on the connecting cylinder 31, at the in-process that the thick liquids were carried, realizes the intercommunication of hole and slip casting 2 through sprue 311, guarantees that the thick liquids in the slip casting 2 can be carried smoothly to the hole in to through the hole on the shutoff construction face of shutoff board 32.

Through setting up pressure relief vent 321, when the thick liquids in the hole were injected into too much in the in-process of slip casting, unnecessary thick liquids can be discharged from pressure relief vent 321, and the air in the hole also can be discharged through pressure relief vent 321 to reach the purpose of pressure relief. Therefore, the pressure relief port 321 is arranged on the plugging plate 32, air and redundant slurry in the hole can be discharged from the pressure relief port 321, the slurry in the hole is saturated, the plugging depth requirement is met, the slurry in the hole can not be extruded out by the other side of the grouting in the plugging process, and the plugging quality and the plugging efficiency of the hole grouting device 100 are improved.

The pressure relief port 321 is arranged in a penetrating manner along the thickness direction of the plugging plate 32, and the pressure relief port 321 arranged in a penetrating manner is used for discharging air and redundant slurry in the hole, meanwhile, the structure of the plugging plate 32 is simple, the processing is convenient, and the production efficiency of the hole grouting device 100 is improved.

Set up elastic component 4 between execution seat 1 and shutoff board 32, when plugging the hole, shutoff board 32 butt is on the construction face, and at this moment, the construction face can give shutoff board 32 effort for shutoff board 32 moves towards the direction of execution seat 1, and elastic component 4 is compressed. Subsequently, the elastic member 4 can drive the plugging plate 32 to move towards the direction of the construction surface by utilizing the self telescopic force so as to keep the pressure of the plugging plate 32 on the construction surface, so that the plugging plate 32 is tightly attached to the construction surface, and the situation that slurry overflows due to insufficient attaching force and the plugging depth cannot be reached is prevented.

The plate-shaped plugging plate 32 has certain deformability, and is used in cooperation with the elastic piece 4, so that the construction surface can be compressed after being pressed, and the plugging quality of the hole grouting device 100 is further improved.

It can be understood that, for prior art, the hole grouting device 100 of this application sets up elastic component 4 between executive seat 1 and shutoff board 32, can guarantee that shutoff board 32 hugs closely all the time on the construction face, and is provided with pressure release port 321 on the shutoff board 32, can discharge the air in the hole and unnecessary thick liquids at the in-process in shutoff hole, reaches the purpose of pressure release, and shutoff is of high quality and shutoff efficient.

Optionally, the elastic member 4 is a spring, and the spring applies pressure to the blocking plate 32 by using its own stretching force, so that the elastic member 4 always drives the blocking plate 32 to face the direction of the construction surface, thereby ensuring that the blocking plate 32 is tightly attached to the construction surface.

Alternatively, the area of the injection port 311 is smaller than the area of the hole. The plugging plate 32 is covered on the hole of the construction surface, part of the structure of the plugging plate 32 can be abutted against the outer surface of the hole, and the part of the pressure relief port 321 can be communicated with the hole, so that the purpose of pressure relief is achieved.

Advantageously, the slip casting pipe 2 can be made of stainless steel pipe, and the stainless steel pipe has the advantages of high rigidity, high durability, corrosion resistance and the like, so that the service life of the slip casting pipe 2 is prolonged.

The slurry referred to in the present application may be a mortar, or may be a fluid material such as paint or pigment; the hole can be a screw hole or any hole capable of being filled with slurry, and the application is not limited.

In some embodiments of the present invention, as shown in fig. 2 and 4, the pressure relief vent 321 is located below the injection port 311. Because the slurry has a certain weight, the pressure relief port 321 is arranged below the injection port 311, and because of gravity, on one hand, when the slurry in the hole is too much, a guide assembly is not needed to be arranged, and the slurry can automatically move towards the pressure relief port 321 and is discharged through the pressure relief port 321; on the other hand, the slurry can continue to flow downwards after passing through the pressure relief opening 321, so that the slurry is prevented from being excessively accumulated at the pressure relief opening 321 to block the pressure relief opening 321, and the pressure relief opening 321 can effectively perform the pressure relief function.

Alternatively, as shown in fig. 2 and 4, the upper end of the relief port 321 is spaced from the injection port 311. That is to say, pressure relief port 321 and sprue 311 interval set up, are provided with part shutoff board 32 between pressure relief port 321 and the sprue 311, and shutoff board 32 here mainly plays the effect that blocks thick liquids, guarantees that thick liquids are not direct from pressure relief port 321 outflow from the in-process that the hole was flowed through from sprue 311 to reach the mesh of shutoff hole.

Alternatively, as shown in fig. 4, the lower end of the relief port 321 penetrates the blocking plate 32 in the downward direction. The pressure relief port 321 has a certain guiding function, when the redundant slurry is discharged from the pressure relief port 321, the slurry can flow downwards along the extending direction of the pressure relief port 321, so that the slurry is prevented from being accumulated at the pressure relief port 321 to block the pressure relief port 321.

Of course, in other examples of the present application, the pressure relief port 321 may be used to primarily vent excess slurry in the hole. The air in the hole can be exhausted in an air exhaust mode, so that the purpose of pressure relief is achieved.

Alternatively, the length of the pressure relief port 321 is greater than the width of the pressure relief port 321, so that the pressure relief port 321 is formed in a long strip structure on the blocking plate 32. Because of the hole grouting device 100 has certain error in the process of plugging the hole, that is to say, the plugging plate 32 is sealed and covered on the hole of the construction surface, the central point of the injection port 311 is not necessarily right opposite to the central point of the hole, the pressure relief port 321 is arranged to be long-strip-shaped structure, certain position deviation can be overcome by the pressure relief port 321 which is long-strip-shaped structure, when the grouting piece 3 has certain deviation relative to the hole, part of the structure of the pressure relief port 321 can be attached to the hole, and the purpose of pressure relief is achieved.

In other examples, the shape of the pressure relief port 321 is not limited to the above structure, and the pressure relief port 321 may also be formed in an oval shape, when the pressure relief port 321 is an oval shape, a major diameter of the oval is taken as a length of the pressure relief port 321, and a minor diameter of the oval is taken as a width of the pressure relief port 321, so that the pressure relief port 321 can also communicate with the hole on the premise that the hole grouting device 100 has a certain error with the hole, thereby achieving the purpose of pressure relief.

Optionally, the width of the pressure relief port 321 is 2.5mm to 3.5 mm. When the width of the pressure relief opening 321 is smaller than 2.5mm, the pressure of the pressure relief opening 321 is too small in the pressure relief process, so that the redundant slurry in the hole cannot be discharged, and the purpose of pressure relief cannot be achieved; when the width of the pressure relief port 321 is larger than 3.5mm, the pressure of the pressure relief port 321 is too high in the pressure relief process, so that excessive slurry is discharged from the pressure relief port 321, and slurry waste can be caused while the hole plugging depth cannot be reached. Therefore, the width of the pressure relief port 321 is set to be 2.5 mm-3.5 mm, so that air in the hole is completely discharged without causing waste of slurry, and the hole meets the requirement of plugging depth.

Of course, in other examples, the width of the pressure relief port 321 is not limited to the above-mentioned setting, and the technician can set the width of the pressure relief port 321 according to the consistency of the pulp, fig. 5 shows a schematic diagram of the consistency of the pulp and the width of the pressure relief port 321, as can be seen from fig. 5, the width of the pressure relief port 321 is inversely proportional to the consistency of the pulp, and the pressure relief port 321 with the width of 2.5mm to 3.5mm is suitable for the pulp with the consistency range of 8cm to 9 cm.

In some embodiments of the invention, the grouting member 3 is movably provided on the grouting pipe 2. It should be noted that the movable part is movable and rotatable, and the grouting member 3 of the hole grouting device 100 of the present application is movable relative to the grouting pipe 2 and rotatable relative to the grouting pipe 2, the movement is mainly realized by the elastic member 4, and the rotation is realized by the following ball joint connection. The grouting piece 3 is movably arranged on the grouting pipe 2, so that the grouting piece 3 can move relative to a construction surface, and the grouting piece 3 is always attached to the construction surface in the process of plugging the hole, thereby improving the plugging quality; with slip casting 3 swingably set up on slip casting 2, at the in-process of shutoff hole, if the wall is not level and smooth enough, slip casting 3 can be adjusted passively for the inclination of slip casting 2, ensure that slip casting 3 can hug closely on the construction face all the time, further improve the shutoff quality.

To sum up, the hole slip casting device 100 of this application can carry out the shutoff to the hole on the hole of co-altitude not, different inclination's the construction face, improves the practicality of hole slip casting device 100.

Alternatively, the grouting member 3 is connected to the grouting pipe 2 by a ball hinge. Ensure that slip casting 3 can swing for slip casting pipe 2 for the hole grouting device 100 of this application can carry out the shutoff to the hole on the not co-altitude, different inclination's the construction face, reduces the shutoff degree of difficulty and improves hole grouting device 100's practicality.

Alternatively, as shown in fig. 3, a spherical structure 21 is provided on the periphery of one side of the grouting pipe 2 close to the grouting member 3, and the spherical structure 21 extends into the connecting cylinder 31, so that the grouting pipe 2 and the connecting cylinder 31 form a spherical hinge connection. Specifically, the inner wall of connecting cylinder 31 is straight tube-shape, and the one end that slip casting pipe 2 is close to connecting cylinder 31 sets up spherical structure 21, and slip casting piece 3 can move relative slip casting pipe 2 and can rotate relative slip casting pipe 2 again like this for slip casting piece 3 can laminate the wall all the time.

The uide bushing 11 can play the guide effect to the removal of elastic component 4 for elastic component 4 can stretch out and draw back in predetermineeing the orientation, through the flexible power of elastic component 4 self and construction face cooperation in order to drive slip casting 3 for slip casting 2 back-and-forth movements, with closely laminating slip casting 3 on the construction face.
