Description

Technical Field

[0001] This utility model relates to the field of grouting equipment technology, and in particular to a grouting device for repairing wall cracks. Background Technology

[0002] Wall crack repair is a technical measure to repair various cracks in building walls. In the process of wall crack repair, grouting equipment is often used to inject concrete or other repair materials into the cracks to repair the cracked wall surface.

[0003] Existing wall crack repair grouting equipment involves placing concrete or other repair materials into the hopper, then holding the spray gun and aiming the nozzle at the wall crack. The electric motor inside the spray gun replaces the traditional pneumatic / hydraulic power, converting electrical energy into mechanical energy to propel the grout, causing it to be sprayed out from the nozzle and injected into the crack, thus completing the repair of the wall crack.

[0004] However, due to the lack of a support mechanism on the spray gun, it may be impossible to temporarily place the spray gun on the ground. Construction workers may need to hold it for a long time, which may prevent them from performing other operations and affect the practicality and ease of use of the spray gun. Utility Model Content

[0005] The technical problem this invention aims to solve is that the lack of a support mechanism on the spray gun may prevent it from being temporarily placed on the ground, requiring construction workers to hold it for extended periods, thus hindering their ability to perform other operations and affecting the practicality and ease of use of the spray gun.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a wall crack repair grouting device, comprising: a spray gun, which is used to carry and output grout; a hopper, which is placed on the spray gun to store grout and to guide the grout into the spray gun; and a support assembly, which is disposed on the spray gun and supports the spray gun placed on the ground or table.

[0007] Preferably, the support assembly includes: a bearing frame fixedly connected to the side of the spray gun away from the hopper; two support rods symmetrically rotatably mounted on the bearing frame; and two stop rods symmetrically fixedly connected to the bearing frame, each stop rod corresponding to and limiting the movement of the two support rods.

[0008] The effect achieved by the above components is as follows: By setting up the support assembly, the two support rods are first manually rotated so that they rotate in opposite directions around the bearing on the bearing bracket. When both support rods are rotated to the position of contact with the surfaces of the two stop rods, the two support rods are arranged in a V-shape. At this time, the spray gun is placed on the ground or table through the two support rods, so that the two support rods support the spray gun, thereby achieving temporary placement of the spray gun. This reduces the situation where construction workers cannot temporarily place the spray gun during construction, which would prevent them from performing other operations, and improves the practicality and ease of use of the spray gun.

[0009] Preferably, a rubber column is fixedly connected to the end of each of the two support rods away from the bearing frame, and the surface of each of the two rubber columns is provided with multiple protrusions.

[0010] The effect achieved by the above components is that by setting rubber columns, the rubber columns can increase the friction between the support rod and the ground or tabletop, reducing the possibility of the support rod slipping.

[0011] Preferably, the support assembly further includes: magnets, wherein two magnets are respectively fixed to adjacent sides of the two support rods, and the two magnets are attracted to each other by magnetism.

[0012] The effect achieved by the above components is that, by setting up magnets, when the two support rods rotate to the position where they merge, the two magnets attract each other and fix the two support rods, reducing the possibility of the two support rods rotating after resetting.

[0013] Preferably, the support assembly further includes: airbags, wherein two airbags are respectively fixed to two support rods, and the positions of the two airbags correspond to the positions of the two stop rods, separating the stop rods from the support rods.

[0014] The effect achieved by the above components is that by setting up airbags, the airbags can separate the surfaces of the stop bar and the support bar, reducing the possibility of collision and wear between the two.

[0015] Preferably, it further includes: a sealing assembly, the sealing assembly comprising: a screw fixedly connected to the hopper, wherein the surface of the screw is threadedly connected to a threaded ring; and a cover plate, wherein the cover plate is fitted onto the screw and fixed by compression through the threaded ring.

[0016] The effect achieved by the above components is as follows: By setting up the sealing component, the cover plate is first manually put on the screw. At this time, the screw hole ring is manually rotated, so that the screw hole ring moves up and down along the surface of the screw. The screw hole ring moves to the position of the extrusion cover plate and is fixed there. This makes the cover plate completely seal the hopper inlet and intercept external debris and slurry inside the hopper. This achieves the sealing and dust protection of the hopper, reduces the possibility of external debris falling into the hopper and affecting the quality of the slurry, and also prevents the slurry inside the hopper from accidentally spilling out.

[0017] Preferably, the surface of the screw hole ring is fixedly connected with a plurality of protrusions, and the plurality of protrusions are arranged at equal intervals.

[0018] The effect achieved by the above-mentioned components is that by setting up protrusions, the hand can be intercepted, reducing the chance of slipping when manually rotating the screw hole ring.

[0019] Preferably, the sealing assembly further includes a rubber pad, wherein the rubber pad is fixed to the cover plate to fill the gap between the cover plate and the hopper.

[0020] The effect achieved by the above components is that the gap between the cover plate and the hopper can be filled and sealed by setting rubber gaskets, reducing the leakage of slurry through the gap.

[0021] The beneficial effects of this utility model are:

[0022] By setting up support components, the spray gun can be temporarily placed on the ground or table during construction, reducing the situation where construction workers cannot temporarily place the spray gun and have to hold it for a long time, which prevents them from performing other operations, thus improving the practicality and ease of use of the spray gun.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1-4 The wall crack repair grouting device shown includes: a spray gun 1, which is used to carry and output grout; a hopper 2, which is placed on the spray gun 1 to store grout and to guide the grout into the spray gun 1; and a support assembly 3, which is disposed on the spray gun 1 and supports the spray gun 1 placed on the ground or table.

[0032] Figure 2 and Figure 3 The support assembly 3 shown includes: a bearing frame 31, which is fixedly connected to the side of the spray gun 1 away from the hopper 2; two support rods 33, which are symmetrically rotated and mounted on the bearing frame 31; and two stop rods 32, which are symmetrically fixedly connected to the bearing frame 31. The two stop rods 32 respectively limit the movement of the two support rods 33. By setting the support assembly 3, the two support rods 33 are first manually rotated so that they rotate in opposite directions around the bearing on the bearing frame 31. When both support rods 33 are rotated to the position of contact with the surfaces of the two stop rods 32, the two support rods 33 are arranged in a V-shape. At this time, the spray gun 1 is placed on the ground or table through the two support rods 33, so that the two support rods 33 support the spray gun 1, thereby achieving temporary placement of the spray gun 1. This reduces the situation where construction personnel cannot temporarily place the spray gun 1 during construction, which would prevent them from performing other operations, and improves the practicality and ease of use of the spray gun 1.

[0033] Figure 2 and Figure 3 The two support rods 33 shown are each fixedly connected to a rubber column 34 at the end away from the bearing frame 31. The surface of each rubber column 34 is provided with multiple protrusions. By setting the rubber column 34, the rubber column 34 can increase the friction between the support rod 33 and the ground or tabletop, reducing the possibility of the support rod 33 sliding. The support assembly 3 also includes a magnet 35, wherein two magnets 35 are respectively fixed to the adjacent side of the two support rods 33. The magnets 35 are attracted to each other. By setting the magnets 35, when the two support rods 33 rotate to the position where they merge, the two magnets 35 attract each other and fix the two support rods 33, reducing the possibility of the two support rods 33 rotating after resetting.

[0034] Figure 2and Figure 3 The support assembly 3 shown also includes an airbag 36, wherein two airbags 36 are respectively fixed to two support rods 33, and the positions of the two airbags 36 correspond to the positions of the two stop rods 32, separating the stop rods 32 from the support rods 33. By setting the airbags 36, the airbags 36 can separate the surfaces of the stop rods 32 and the support rods 33, reducing the possibility of collision and wear between the two.

[0035] Figure 4 The device also includes a sealing assembly 4, which comprises a screw 41 fixed to the hopper 2, wherein the surface of the screw 41 is threaded with a screw hole ring 43; and a cover plate 42, wherein the cover plate 42 is fitted onto the screw 41 and fixed by the screw hole ring 43. By setting the sealing assembly 4, the cover plate 42 is first manually fitted onto the screw 41. At this time, the screw hole ring 43 is manually rotated, causing the screw hole ring 43 to move up and down along the surface of the screw 41, so that the screw hole ring 43 moves to the position of pressing the surface of the cover plate 42 and fixing it there. This makes the cover plate 42 completely seal the inlet of the hopper 2 and intercept external debris and the slurry inside the hopper 2, thereby achieving the sealing and dust protection of the hopper 2, reducing the possibility of external debris falling into the hopper 2 and affecting the quality of the slurry, and preventing the slurry inside the hopper 2 from accidentally spilling out.

[0036] Figure 4 The surface of the screw hole ring 43 shown is fixedly connected with multiple protrusions 44, which are arranged at equal intervals. By setting the protrusions 44, the hand can be intercepted, reducing the possibility of slippage when manually rotating the screw hole ring 43. The sealing component 4 also includes a rubber pad 45, which is fixed to the cover plate 42 to fill the gap between the cover plate 42 and the hopper 2. By setting the rubber pad 45, the gap between the cover plate 42 and the hopper 2 can be filled and sealed, reducing the leakage of slurry through the gap.

[0037] Working principle: First, put concrete or other repair materials into the hopper 2. Then, hold the spray gun 1 and aim the nozzle of the spray gun 1 at the crack in the wall. Then, the electric motor inside the spray gun 1 replaces the traditional pneumatic / hydraulic power. The electric energy is converted into mechanical energy to drive the grout, so that the grout is sprayed out from the nozzle of the spray gun 1 and injected into the crack, thereby completing the repair of the crack in the wall.

[0038] First, manually rotate the two support rods 33 so that they rotate in opposite directions around the bearing on the bearing bracket 31. When both support rods 33 are rotated to the position where they are in contact with the surfaces of the two stop rods 32, the two support rods 33 are arranged in a V-shape. At this time, place the spray gun 1 on the ground or table through the two support rods 33 so that the two support rods 33 support the spray gun 1, thereby achieving temporary placement of the spray gun 1.

[0039] First, manually put the cover plate 42 onto the screw 41. Then, manually rotate the screw hole ring 43 so that the screw hole ring 43 moves up and down along the surface of the screw 41. The screw hole ring 43 moves to the position of pressing the cover plate 42 and fixing it there. This makes the cover plate 42 completely seal the inlet of the hopper 2 and intercept external debris and slurry inside the hopper 2, thereby achieving the sealing and dust protection of the hopper 2.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
