Description

Technical Field

[0001] This utility model relates to the field of lightweight shotcrete mixing technology, and in particular to a lightweight integrated shotcrete mixing device for use in mountainous areas. Background Technology

[0002] The application fields of shotcrete equipment have gradually expanded from the initial industrial coating and underground engineering support to multiple fields such as construction, mining, water conservancy, and transportation. In the construction field, it is used for foundation pit slope support and building wall spraying; in the mining field, it is used for mine tunnel support and repair; in the water conservancy field, it is used for surface treatment and repair of dams and canals; and in the transportation field, it is used for lining construction of highway and railway tunnels.

[0003] Large shotcrete equipment is bulky and heavy, making it inconvenient to move and transport. In some construction sites, especially in areas with narrow spaces or complex terrain, such as turns in tunnel construction or small working faces in mines, the mobility of the equipment is greatly limited, making it difficult to reach the designated location for shotcrete operations. Alternatively, a lot of time and effort may be required to disassemble, transport, and reassemble the equipment during the move, which affects construction efficiency.

[0004] While some small shotcrete equipment is relatively flexible, it often fails to meet the needs of large-scale projects in terms of power and spraying capacity, resulting in a contradiction between mobility and working capacity. Utility Model Content

[0005] The purpose of this invention is to address the problem that while some existing small shotcrete equipment is relatively flexible, it often fails to meet the needs of large-scale projects in terms of power and spraying capacity, resulting in a contradiction between mobility and working capacity. Therefore, this invention proposes a lightweight integrated shotcrete mixing device for use in mountainous areas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight integrated spraying and mixing device for mountainous areas, comprising a pressure device, wherein a first mixing device, a second mixing device and a spraying device are mounted on the top of the pressure device via a fixing mechanism, and fixing rings are fixedly installed on the outside of the first mixing device, the second mixing device and the spraying device.

[0007] The fixing mechanism includes a rotating shell, on both sides of the inner wall of the rotating shell, nuts are fixedly installed, and screw rods are threaded to the inner walls of the two nuts. Support plates are fixedly installed at opposite ends of the two screw rods, and connecting rods are fixedly installed on opposite sides of the two support plates. A hook is fixedly installed at the top of the upper connecting rod, and a bracket is rotatably connected to the bottom of the lower connecting rod.

[0008] Furthermore, the threads on the inner walls of the two nuts are opposite, and a handle is fixedly installed on both sides of the rotating shell. Rod holes adapted to the lead screw are opened at both ends of the rotating shell.

[0009] Furthermore, the bottom of the retaining ring is fixedly mounted on the top of the pressure device, and the hook is suspended on the retaining ring.

[0010] Furthermore, a switching device is connected between the first and second mixing devices, and the output end of the spraying device is connected to a spray gun via a hose.

[0011] Furthermore, the switching device includes a device housing fixedly installed on the top of the pressure device. Sealing rings are installed on both sides of the device housing, and an inclined tube is connected inside the two sealing rings. A limit frame is fixedly installed on the top of the device housing, and a blocking plate is slidably connected inside the limit frame. A drive rod is fixedly inserted through the blocking plate, and a blocking rod is fixedly installed at the bottom of the drive rod.

[0012] Furthermore, the top of the device housing is provided with an oblong through hole, and the oblong through hole is adapted to the drive rod, and the length of the blocking plate is greater than the length of the oblong through hole.

[0013] Furthermore, the diameter of the plug rod is adapted to the inner wall diameter of the inclined tube.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, during disassembly, rotating the handle causes the rotating shell to rotate, which in turn causes the two nuts to rotate in opposite directions. The two nuts rotate outside the two lead screws, causing the two lead screws to move outward. The two lead screws then move the two support plates outward, and the support plates move the two connecting rods outward, causing the hook to disengage from the fixing ring. This disengages the outlet ends of the first and second mixing devices from the switching device, and separates the spraying device from the air compressor. The first mixing device, the second mixing device, and the spraying device can then be removed, making them lightweight and convenient for transportation.

[0016] 2. In this utility model, when the first stirring device is stirring, the second stirring device has finished stirring. The driving rod is moved, and the driving rod drives the blocking plate to move. The blocking plate moves in the limiting frame, and the limiting frame limits the blocking plate. The driving rod drives the blocking rod to move. The blocking rod leaves the inclined tube on the right side and blocks the inclined tube on the left side, which can perform diversion stirring and has higher efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a lightweight integrated shotcrete mixing device for mountainous areas, comprising a pressure device 1, a first mixing device 3, a second mixing device 4, and a shotcrete device 5 mounted on the top of the pressure device 1 via a fixing mechanism 2, with a mixing capacity of 0.5-1.5m³. 3h, low power, the first mixing device 3, the second mixing device 4 and the spraying device 5 are all fixedly installed with fixing rings 9 on the outside, the fixing mechanism 2 includes a rotating shell 21, nuts 24 are fixedly installed on both sides of the inner wall of the rotating shell 21, the inner walls of the two nuts 24 are threaded with screw rods 22, the opposite ends of the two screw rods 22 are fixedly installed with support plates 25, the opposite sides of the two support plates 25 are fixedly installed with connecting rods 27, the top of the upper connecting rod 27 is fixedly installed with a hook 28, the bottom of the lower connecting rod 27 is rotatably connected with a bracket 26, the threads of the inner walls of the two nuts 24 Conversely, both sides of the rotating shell 21 are fixedly equipped with levers 23, and both ends of the rotating shell 21 are provided with rod holes that are compatible with the lead screw 22. The bottom of the fixing ring 9 is fixedly installed on the top of the pressure device 1, and the hook 28 is suspended on the fixing ring 9. A switching device 8 is connected between the first stirring device 3 and the second stirring device 4. The output end of the spraying device 5 is connected to the spray gun 7 through the hose 6. The input end of the spraying device 5 is connected to the output end of the pressure device 1. The pressure device 1 includes a shell and an air compressor. The spraying device 5 and the switching device 8 are both connected to the air compressor. The bracket 26 is installed on the shell.

[0028] In this embodiment, during disassembly, rotating the lever 23 causes the rotating shell 21 to rotate, which in turn causes the two nuts 24 to rotate in opposite directions. The two nuts 24 rotate outside the two lead screws 22, causing the two lead screws 22 to move outward. The two lead screws 22 then cause the two support plates 25 to move outward, and the support plates 25 cause the two connecting rods 27 to move outward. This causes the hook 28 to disengage from the fixing ring 9, disengaging the outlet ends of the first mixing device 3 and the second mixing device 4 from the switching device 8. The spraying device 5 and the air compressor are then disconnected. The first mixing device 3, the second mixing device 4, and the spraying device 5 can be removed, making them lightweight and convenient for transportation.

[0029] Example 2

[0030] like Figure 1-4 As shown, the switching device 8 includes a device housing 81 fixedly installed on the top of the pressure device 1. Sealing rings 82 are installed on both sides of the device housing 81. An inclined tube 83 connects the interior of the two sealing rings 82. A limit frame 84 is fixedly installed on the top of the device housing 81. A blocking plate 85 is slidably connected inside the limit frame 84. A drive rod 86 is fixedly inserted through the blocking plate 85. A blocking rod 87 is fixedly installed at the bottom of the drive rod 86. A waist-shaped through hole is opened on the top of the device housing 81, and the waist-shaped through hole is adapted to the drive rod 86. The length of the blocking plate 85 is greater than the length of the waist-shaped through hole. The diameter of the blocking rod 87 is adapted to the inner wall diameter of the inclined tube 83. The discharge ports of the first stirring device 3 and the second stirring device 4 are sealed to the sealing rings 82. A discharge port adapted to the air compressor is opened at the bottom of the device housing 81.

[0031] In this embodiment, when the first stirring device 3 is stirring, the second stirring device 4 has finished stirring. The driving rod 86 is moved, and the driving rod 86 drives the blocking plate 85 to move. The blocking plate 85 moves in the limiting frame 84, and the limiting frame 84 limits the blocking plate 85. The driving rod 86 drives the blocking rod 87 to move. The blocking rod 87 leaves the inclined tube 83 on the right side and blocks the inclined tube 83 on the left side, so that the flow can be divided and stirred.

[0032] Working principle: such as Figure 1-4 As shown, during disassembly, rotating the lever 23 causes the rotating shell 21 to rotate, moving the two lead screws 22 outward. The two lead screws 22 then move the two support plates 25 outward, which in turn move the two connecting rods 27 outward, causing the hook 28 to disengage from the fixing ring 9. This disengages the outlet ends of the first mixing device 3 and the second mixing device 4 from the switching device 8, and separates the spraying device 5 from the air compressor. The first mixing device 3, the second mixing device 4, and the spraying device 5 can then be removed, making them lightweight and convenient for transportation. When the first mixing device 3 is mixing, the second mixing device 4 has finished mixing. Moving the drive rod 86 causes the blocking rod 87 to move, and the blocking rod 87 leaves the inclined pipe 83 on the right side, blocking the inclined pipe 83 on the left side, allowing for diversion mixing.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
