Description

Technical Field

[0001] This utility model relates to the technical field of inclined shaft construction equipment, specifically to a spraying device for waterproof construction of inclined shafts. Background Technology

[0002] In mining engineering, inclined shafts serve as crucial passages connecting surface and underground mining areas, undertaking multiple tasks such as personnel and equipment transport, and ore hoisting. Their structural stability and waterproofing performance are paramount. To ensure the waterproofing effect of inclined shafts, shotcrete treatment is typically applied to their inner walls to form a protective waterproof layer. However, existing shotcrete systems have several shortcomings in the waterproofing process of inclined shafts, particularly when spraying corners and hard-to-reach areas.

[0003] Traditional shotcrete systems are often designed to be bulky, and their weight increases significantly when filled with grout. This means that when precise spraying is needed at corners or specific locations in an inclined shaft, workers must laboriously move the entire system to ensure the spray nozzles are correctly oriented and positioned. However, due to the weight and size of the shotcrete system, this movement is not only time-consuming and labor-intensive, but can also lead to interruptions in the spraying process and uneven application, thus affecting the waterproofing effect of the inclined shaft.

[0004] Furthermore, existing shotcrete devices are often not flexible enough in adjusting the spraying angle and range. When faced with the complex and varied corners and curved surfaces inside inclined shafts, traditional shotcrete devices struggle to achieve precise spraying, resulting in inconsistent quality of the waterproofing layer and potential leakage risks. Summary of the Invention

[0005] The purpose of this utility model is to provide a spraying device for waterproofing construction of inclined shafts, so as to solve the many shortcomings of the existing spraying devices mentioned in the background art in the process of waterproofing construction of inclined shafts, especially when spraying corners and hard-to-reach areas of the inclined shaft, the problem is particularly prominent.

[0006] To achieve the above objectives, this utility model provides a spraying device for waterproofing construction of inclined shafts, including a support frame, a storage box mounted on the support frame, a connecting plate connected to the lower part of the support frame, a first motor mounted at one end of the connecting plate, and a second motor mounted at the bottom of the other end. The output shaft of the first motor is fixedly connected to one end of a swing arm via a second rotating shaft. The output shaft of the second motor is mounted with a first rotating shaft, which is rotatably connected to one end of the swing arm. A first bevel gear is mounted on the outer end of the first rotating shaft. A support platform is rotatably mounted above the swing arm, and a spray head is mounted on the support platform. A connecting rod is fixed to the bottom of the support platform, and a second bevel gear is mounted at the bottom end of the connecting rod. The second bevel gear meshes with the first bevel gear. The connecting rod is inserted into the swing arm. A discharge pipe is provided at the bottom of the storage box, and the spray head is connected to the discharge pipe via a flexible pipe.

[0007] Preferably, rollers are installed on both sides of the lower part of the support frame, and a support block is connected to the bottom of the support frame on the side away from the rollers. An anti-slip pad is connected below the support block, and both the anti-slip pad and the rubber pad are provided with anti-slip patterns.

[0008] Preferably, a push rod is installed on the top of the support frame.

[0009] Preferably, the swing arm has a U-shaped design, and the end of the swing arm away from the first motor is rotatably connected to the first rotating shaft through a bearing.

[0010] Preferably, both the first motor and the second motor are fixed to the connecting plate by a mounting plate.

[0011] Preferably, the top of the storage bin is hinged with a cover.

[0012] Preferably, a fixing plate is installed on the upper part of the support frame, a third motor is installed on the fixing plate, the output shaft of the third motor is connected to a rotating rod, one end of the rotating rod passes through the storage box and extends into the discharge pipe and is connected to a stirring blade, the stirring blade being a spiral design.

[0013] Preferably, a fixing block is installed on one side of the cover, and a slot is provided on the surface of the fixing block. A hollow plate is installed on the upper outer side of the storage box, and a locking block is provided inside the hollow plate. A spring is installed on one side of the locking block, and a rubber pad is installed on the other side of the locking block. The side of the locking block facing the fixing block is designed as a right-angled triangle and engages with the slot.

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

[0015] The shotcrete device used for waterproofing inclined shafts utilizes a swing arm, a first motor, a second motor, and corresponding first and second bevel gears to achieve flexible multi-angle adjustment of the spray head. This allows the shotcrete device to easily and precisely spray corners and hard-to-reach areas of the inclined shaft without moving the overall position, greatly improving construction flexibility and efficiency.

[0016] Because the angle and position of the spray head can be precisely adjusted via motor drive, workers no longer need to laboriously move the entire spraying device. This not only reduces labor intensity but also avoids problems such as interruption of the spraying process and uneven spraying caused by moving the device, thus ensuring the continuity and uniformity of the waterproof layer in the inclined well.

[0017] By flexibly adjusting the angle and position of the spray head, the spraying device of this invention can more accurately cover the inner wall of the inclined shaft, especially the corners and curved surfaces. This helps to form a more complete and uniform waterproof layer, thereby effectively improving the waterproof performance of the inclined shaft and reducing the risk of leakage.

[0018] The rollers and support blocks located beneath the support frame, along with the anti-slip texture on the anti-slip pads and rubber mats, collectively enhance the stability of the shotcrete device during construction. This helps prevent the device from shaking or slipping during spraying, further ensuring the accuracy and safety of the construction process.

[0019] The sealing cap on top of the storage tank is designed for easy opening and closing, facilitating the addition and cleaning of grout. Meanwhile, the inclusion of a third motor and agitator blades helps maintain the uniformity of the grout, preventing material sedimentation from affecting the spraying effect. Furthermore, the fixing blocks and slots on the cap, along with the hollow plate, locking blocks, springs, and rubber pads on the storage tank, collectively constitute a convenient cap fixing mechanism, simplifying operation and maintenance.

Detailed Implementation

[0026] 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.

[0027] This utility model provides a shotcrete device for waterproofing construction of inclined shafts, such as... Figures 1-3 As shown, the device includes a support frame 1, a storage box 4 mounted on the support frame 1, a connecting plate 6 connected below the support frame 1, a support platform 14 mounted on the connecting plate 6, a spray head 15 mounted on the support platform 14, a bottom connecting rod 13 of the support platform 14 connected to a swing arm 17 via a rotating bearing, and the support platform 14 and the swing arm 17 are rotatably connected. A first motor 9 is mounted at the bottom of one end of the swing arm 17, and a second motor 8 is mounted at the bottom of the other end. The output shaft of the first motor 9 is fixedly connected to the swing arm 17 via a second rotating shaft 16. A first rotating shaft 10 is mounted on the output shaft of the second motor 8. A first bevel gear 11 is mounted on the outer end of the first rotating shaft 10. A connecting rod 13 is fixed at the bottom of the support platform 14. The bottom end of the connecting rod 13 passes through the swing arm 17 and is mounted with a second bevel gear 12. The second bevel gear 12 meshes with the first bevel gear 11. A discharge pipe 18 is provided at the bottom of the storage box 4, and the spray head 15 is connected to the discharge pipe 18 via a flexible pipe. One end of the swing arm 17 in the device is fixedly connected to the first motor 9 and the second rotating shaft 16, while the other end is rotated by the first rotating shaft 10 and the bevel gear set (including the first bevel gear 11 and the second bevel gear 12) driven by the second motor 8. This design allows the spray head 15 to be flexibly adjusted at multiple angles in both horizontal and vertical directions, thereby meeting the spraying needs of different positions and angles on the inner wall of the inclined well.

[0028] Because the angle of the spray head 15 can be precisely controlled by a motor, accurate spraying can be achieved in the corners and hard-to-reach areas of the inclined shaft. This not only improves construction efficiency but also ensures the continuity and uniformity of the waterproof layer, thereby enhancing the waterproof performance of the inclined shaft.

[0029] The device is designed with the complexity of the inclined shaft construction environment in mind. Through the cooperation of the swing arm 17 and the bevel gear set, the spray head 15 can easily adapt to the curved surface and corners of the inclined shaft inner wall, achieving all-round, no-dead-angle spray coverage.

[0030] The motor-driven design makes adjusting the spray head simple and quick, eliminating the need for manual labor to move the entire spraying device. This not only reduces the workload of workers but also improves construction safety and efficiency.

[0031] In this embodiment, rollers 5 are installed on both sides of the lower part of the support frame 1, which improves the flexibility and convenience of construction. A support block 29 is connected to the bottom of the support frame 1 on the side away from the rollers 5, and an anti-slip pad 30 is connected below the support block 29. Both the anti-slip pad 30 and the rubber pad 27 are provided with anti-slip textures. This enhances the stability of the device during construction, prevents construction deviations caused by uneven ground or slippage, and ensures the accuracy and safety of spraying.

[0032] Specifically, a push rod 2 is installed on the top of the support frame 1. This allows workers to easily push or pull the shotcrete device, further improving the convenience and efficiency of construction.

[0033] Furthermore, the swing arm 17 features a U-shaped design, which not only enhances its structural strength but also makes it more stable during rotation. The end of the swing arm 17 furthest from the first motor 9 is rotatably connected to the first rotating shaft 10 via a bearing. This enables flexible rotation of the swing arm and provides the possibility for multi-angle adjustment of the spray head.

[0034] Furthermore, both the first motor 9 and the second motor 8 are fixed to the connecting plate 6 via the mounting plate 7. This fixing method is not only stable and reliable, but also facilitates the maintenance and replacement of the motors.

[0035] Furthermore, the top of the storage bin 4 is hinged with a cover 20. This facilitates the addition or removal of grouting material by workers, improving construction efficiency.

[0036] Furthermore, a fixing plate 3 is installed on the upper part of the support frame 1, and a third motor 22 is installed on the fixing plate 3. The output shaft of the third motor 22 is connected to a rotating rod 23. One end of the rotating rod 23 passes through the storage tank 4 and extends into the discharge pipe 18, and is connected to an agitator blade 24. The agitator blade 24 has a spiral design. The spiral design of the agitator blade ensures that the grouting material is fully mixed in the storage tank 4, maintaining the uniformity of the grouting material and avoiding the impact of material sedimentation on the spraying effect.

[0037] Furthermore, a fixing block 21 is installed on one side of the cover 20, and a slot 28 is provided on the surface of the fixing block 21. A hollow plate 19 is installed on the upper outer side of the storage box 4, and a locking block 26 is provided inside the hollow plate 19. A spring 25 is installed on one side of the locking block 26, providing sufficient elasticity so that the locking block can be tightly locked in the slot. The rubber pad 27 increases the sealing and wear resistance of the locking point. A rubber pad 27 is installed on the other side of the locking block 26. The side of the locking block 26 facing the fixing block 21 has a right-angled triangular design and engages with the slot 28. The right-angled triangular design of the locking block 26 facilitates the quick opening and closing of the cover, while also ensuring the firmness of the locking, improving the safety and efficiency of construction, and achieving a stable fixation of the cover.

[0038] When using the grouting device for waterproofing inclined shaft construction of this utility model, firstly, move the grouting device to a suitable position at the inclined shaft construction site via the rollers 5 at the bottom of the support frame 1. Adjust the support block 29 and anti-slip pad 30 to ensure the stability of the device during construction. Open the cap 20 on the top of the storage tank 4 and add sufficient grouting material into the storage tank. Close the cap 20 and secure it firmly using the cooperation of the fixing block 21, the slot 28, the locking block 26, the spring 25, and the rubber pad 27.

[0039] Based on the specific location and angle requirements of the inclined shaft's inner wall, the angle of the spray head 15 is adjusted by controlling the operation of the first motor 9 and the second motor 8. The first motor 9 drives one end of the swing arm 17 to rotate via the second rotating shaft 16, thereby causing the support platform 14 to rotate up and down by a certain angle. The second motor 8 drives the connecting rod 13 via the first rotating shaft 10 and the bevel gear set (including the first bevel gear 11 and the second bevel gear 12), thereby causing the support platform 14 to rotate and realizing the horizontal rotation of the spray head. Through the above adjustments, it is ensured that the spray head 15 can be accurately aligned with the area to be sprayed on the inner wall of the inclined shaft.

[0040] The third motor 22 is started, driving the stirring blades 24 to rotate within the storage tank 4 via the rotating rod 23, thoroughly mixing the grouting material and maintaining its uniformity. The valve of the discharge pipe 18 is opened, allowing the grouting material to flow into the spray head 15 through the pipe. The spray head 15 evenly sprays the grouting material onto the inner wall of the inclined shaft, forming a waterproof layer.

[0041] During construction, if the shotcrete device needs to be moved, it can be easily pushed or pulled to the next construction position using push rod 2. The angle of the spray head can be adjusted at any time by controlling the motor according to the curves and corners of the inclined shaft wall, ensuring all-round, no-dead-angle spray coverage.

[0042] After spraying is complete, close the valve on the discharge pipe 18 to stop the flow of grout. Open the cover 20, empty the remaining grout in the storage tank 4, and clean and maintain the equipment. Move the spraying device to a safe area and wait for the next use.

[0043] Finally, it should be noted that the electronic components in the first motor 9, the second motor 8, the third motor 22, etc. in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.

All of these are technologies known in the art.
