Technical Field

[0001] This utility model relates to the technical field of concrete spraying, and in particular to a concrete spraying device. Background Technology

[0002] A concrete spraying truck is a specialized piece of equipment that integrates mixing, conveying, and spraying. It mixes precast materials and water in a specific ratio, then uses compressed air to spray the concrete onto designated locations, forming a uniform and dense concrete protective layer for support and waterproofing. Concrete spraying trucks offer advantages such as fast construction speed, high efficiency, and good construction quality, and are widely used in construction projects.

[0003] However, in existing wall surface shotcrete reinforcement operations, most still rely on manual labor to hold the shotcrete nozzle and enter the designated area, continuously adjusting the nozzle position to perform complex actions such as circumferential spraying. This process is not only extremely labor-intensive, severely restricting the efficiency of shotcrete operations, but also directly affects the final effect of the shotcrete due to the difficulty in ensuring the uniformity and regularity of the spraying by manual operation, thereby weakening the overall stability of the wall. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a concrete spraying device that can adjust the angle and circumferential adjustment of the spraying head with the help of the assembly, without the need for manual labor, effectively reducing the labor intensity of the operator, and significantly improving the efficiency and quality of the spraying operation, thus achieving efficient and precise spraying operation.

[0006] To achieve the above objectives, this utility model proposes a concrete spraying device, including a spraying body, a spraying head, and a conveying hose.

It also includes an assembly, wherein a first adjusting part is provided on one side of the assembly, and a limiting hole is provided on the first adjusting part, with the input end of the spraying head movably disposed within the limiting hole; a second adjusting part is provided on one side of the first adjusting part, and a driving mechanism is provided on the second adjusting part. The output end of the driving mechanism is connected to a clamp, which is movably engaged on the outside of the spraying head.

[0007] In addition, the concrete spraying device proposed in the application may also have the following additional technical features:

[0008] Specifically, an arc-shaped bracket is provided on one side of the limiting hole, and an end shell that cooperates with the arc-shaped bracket is fitted on one end of the spray head, and the end shell is movably embedded in the arc-shaped bracket.

[0009] Specifically, a mounting groove is provided on the other side of the limiting hole, a rack is slidably provided in the mounting groove, an incomplete gear is provided on the outer side of the end shell, the incomplete gear meshes with the rack, and the two ends of the rack pass through the fitting respectively and are provided with a first pull rope and a second pull rope.

[0010] Specifically, the drive mechanism includes a motor, an eccentric wheel, and a connecting frame, wherein the motor is mounted on the second adjustment part; the eccentric wheel is connected to the output end of the motor; one end of the connecting frame is movably sleeved on the outside of the eccentric wheel, and the other end of the connecting frame is fixedly connected to the clamp.

[0011] Specifically, the assembly is equipped with a wearable module, which consists of three shoulder straps. One end of each shoulder strap is fixedly connected, and the other end is detachably connected via a buckle. One of the shoulder straps is fixedly connected to the assembly.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. This application enables the angle and circumferential adjustment of the shotcrete head with the help of the assembly, eliminating the need for manual labor, effectively reducing the labor intensity of operators, and significantly improving the efficiency and quality of shotcrete operations, thus achieving efficient and precise shotcrete operations.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The concrete spraying device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, the concrete spraying device of this utility model embodiment may include a spraying body 101, a spraying head 102 and a conveying hose 103, with the two ends of the conveying hose 103 connected to the discharge end of the spraying body 101 and the input end of the spraying head 102, respectively.

[0025] It should be noted that the shotcrete body 101 described in this embodiment can receive shotcrete material and has the function of conveying the shotcrete material to the shotcrete head 102 through the conveying hose 103. Since the shotcrete body 101 belongs to the existing mature technology, it will not be described in detail here.

[0026] It may also include a mounting part 20, on one side of which is provided a first adjusting part 21. The first adjusting part 21 is provided with a limiting hole 211, and the input end of the spray head 102 is movably disposed in the limiting hole 211. An arc-shaped bracket 2111 is provided on one side of the limiting hole 211, and one end of the spray head 102 is fitted with an end shell 1021 that cooperates with the arc-shaped bracket 2111. The end shell 1021 is movably embedded in the arc-shaped bracket 2111. On the other side of the limiting hole 211, there is a mounting groove 2112. A rack 202 is slidably provided in the mounting groove 2112. An incomplete gear 212 is provided on the outer side of the end shell 1021. The incomplete gear 212 meshes with the rack 202. Both ends of the rack 202 pass through the mounting accessory 20 and are provided with a first pull rope 203 and a second pull rope 204. By cooperating with the first pull rope 203 and the second pull rope 204, the rack 202 can be controlled to move accordingly in the mounting groove 2112.

[0027] It should be noted that the end shell 1021 described in this embodiment can be adjusted in the vertical direction relative to the first adjustment part 21, so as to adapt to the needs of shotcreting operations at different heights.

[0028] A second adjustment part 22 is provided on one side of the first adjustment part 21. A drive mechanism 30 is provided on the second adjustment part 22. The output end of the drive mechanism 30 is connected to a clamp 40, which is movably locked on the outside of the spray head 102.

[0029] It should be noted that the clamp 40 described in this embodiment is located near the output end of the shotcrete head 102. Its design allows the shotcrete head 102 to perform a circumferential motion with the end shell 1021 as the center of motion when the drive mechanism 30 drives the clamp 40 to perform a circumferential motion, thereby ensuring that the output end of the shotcrete head 102 can perform a circumferential shotcrete operation.

[0030] In addition, the clamp 40 also has a certain degree of deformation adaptability to ensure a stable clamping of the shotcrete head 102.

[0031] The drive mechanism 30 may include a motor 31, an eccentric wheel 32, and a connecting frame 33. The motor 31 is mounted on the second adjusting part 22, the eccentric wheel 32 is connected to the output end of the motor 31, one end of the connecting frame 33 is movably sleeved on the outside of the eccentric wheel 32, and the other end of the connecting frame 33 is fixedly connected to the clamping support 40. The connecting frame 33 and the eccentric wheel 32 are inseparable.

[0032] The accessory 20 is equipped with a wearable module 50, which consists of three shoulder straps 51. One end of each shoulder strap 51 is fixedly connected, and the other end is detachably connected via an adjustable buckle 60. One of the shoulder straps 51 is fixedly connected to the accessory 20.

[0033] It should be noted that the shotcrete head 102 described in this embodiment can be easily fixed to the operator's body through the wearable module 50, which not only further saves the operator's physical strength, but also greatly enhances the operator's flexibility in the operation process, and significantly improves the efficiency and accuracy of shotcrete operation.

[0034] Specifically, during the actual shotcreting operation, the personnel first place the shotcreting body 101 in a suitable position, then pass the three shoulder straps 51 under the armpits and one shoulder respectively, and secure them with buckles 60. Next, insert one end of the shotcreting head 102 into the limiting hole 211, so that the end shell 1021 can be flexibly embedded in the arc-shaped bracket 2111. Then, from the other side, introduce one end of the delivery pipe into the limiting hole 211 and connect it to the shotcreting head 102, so that the clamp 40 is locked on the outside of the shotcreting head 102.

[0035] Once the shotcrete head 102 is installed, the operator can start the shotcrete body 101 and smoothly transport the shotcrete material to the shotcrete head 102 through the conveying hose 103. Finally, the shotcrete head 102 completes the shotcrete operation.

[0036] During shotcreting operations, operators can flexibly adjust the angle of the shotcrete head 102 and achieve circular motion using the attachment 20. By manipulating the first pull rope 203 and the second pull rope 204, the rack 202 can be moved, which in turn causes the incomplete gear 212 to rotate the end shell 1021 relative to the first adjustment part 21, thereby adjusting the angle of the shotcrete head 102. In addition, by driving the eccentric wheel 32 to rotate through the motor 31, the connecting frame 33 can perform circular motion with the rotation of the eccentric wheel 32, thus realizing circular shotcreting operations.

[0037] In summary, the concrete spraying device of this utility model embodiment can achieve angle and circumferential adjustment of the spraying head with the help of the assembly, without the need for manual labor, effectively reducing the labor intensity of the operator, and significantly improving the efficiency and quality of the spraying operation, thus achieving efficient and precise spraying operation.
