Description

Technical Field

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

[0002] Concrete pouring is a very frequent part of building construction. Furthermore, the shape of the wall varies depending on its purpose, including shear walls with rectangular cross-sections, retaining walls with rectangular cross-sections, and guardrail walls.

[0003] After concrete construction, the concrete structure walls need to be sprayed with water for curing to prevent cracking. In existing technologies, to improve the efficiency of spray curing, automatic spraying devices are often designed to replace traditional manual spraying.

[0004] The reason is that the length or number of walls under construction is large, and the total amount of spraying work is very large. Therefore, traditional manual spraying cannot meet the needs of spraying maintenance, such as the guardrail walls on highways, which are several kilometers or even more than ten kilometers long.

[0005] In the prior art, the water tank for spraying is placed on a traveling trolley, which is then placed on the top surface of the wall and moves along the top surface of the wall while spraying water.

[0006] However, in actual operation, it was found that due to the different uses of wall structures, their thickness and shape often vary. For example, retaining walls, shear walls, and guardrail walls all have different shapes, resulting in poor versatility of existing spraying carts. For instance, a cart suitable for spraying shear walls of a specific thickness (width) may not be able to move smoothly on guardrail walls or retaining walls due to the different wall thicknesses and shapes. The cart is prone to losing balance and falling while moving on the wall. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a concrete wall spray curing device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A concrete wall spray curing device, comprising a walking spray curing mechanism that moves along the wall; The mobile spraying maintenance mechanism includes a mobile frame, on which a spraying water tank is loaded, and the spraying water tank is connected to a spraying pipe structure that sprays water onto the wall for maintenance. It also includes several adjusting arm roller structures to prevent the walking frame from swaying, and the adjusting arm roller structures roll against the side walls on both sides of the wall. The adjusting arm roller structure includes a fixed arm fixedly installed on the walking frame, an adjusting arm hinged to the fixed arm, and an adjustable abutment structure with an adjustable angle installed at the lower end of the adjusting arm. The adjusting arm adjusts the posture by pushing the structure.

[0009] Preferably, the bottom sides of the walking frame are respectively equipped with rolling structures that roll at the top of the wall.

[0010] Preferably, the rolling structure includes a roller, with bearing brackets rotatably connected to both ends of the roller, and the bearing brackets are fixedly mounted on the walking frame; A thickened rubber sleeve is fixedly connected to the roller. A motor that drives the rollers to rotate is installed on one side of the bottom of the frame.

[0011] Preferably, the pushing structure includes an electrically operated telescopic rod hinged to the adjusting arm; The telescopic end of the electric telescopic rod is fixedly connected to a hinge seat, and the adjusting arm is fixedly connected to a pin hinged to the hinge seat. The top of the electric telescopic rod is fixedly connected to a hinge seat, and a hinge opening is provided on the inner side of the fixed arm. The hinge seat is hinged and installed in the hinge opening by a pin.

[0012] Preferably, the abutment structure includes an abutment roller, and a hinge plate is fixedly connected to the roller frame of the abutment roller. The hinge plate is hingedly installed in the hinge interface opened at the lower end of the adjusting arm. A small motor that drives the hinge plate to rotate is fixedly installed on the adjusting arm.

[0013] Preferably, the outer end of the fixed arm is provided with a hinge interface, and the top of the adjusting arm is hinged to the hinge interface by a fixed pin.

[0014] Preferably, a number of mounting brackets are fixedly connected to the lower end of the outer side wall of the spray tank, and the mounting brackets are fastened to the traveling bracket by bolts.

[0015] Preferably, the spray pipe structure includes a drain pipe connected to the lower end of the side walls on both sides of the spray water tank, and the drain pipe is connected to a horizontal pipe; Several nozzles that spray water toward the wall are connected and installed on the horizontal pipe.

[0016] Preferably, the nozzle is tilted downwards.

[0017] This utility model has the following beneficial effects: 1. During operation, when the entire device (walking support) is placed on the wall, the four adjusting arm roller structures adjust their posture. Specifically, by pushing the adjusting arm, the support roller structure is pulled closer to the wall side by the pushing structure. Subsequently, the support roller structure adjusts its posture, so that the support rollers on the support roller structure are in a vertical position against the wall. The rolling direction of the support rollers is synchronized with the forward direction.

[0018] Under the aforementioned structural action, the adjusting arm and the abutment wheel structure roll against the wall, while the two sides of the traveling bracket are clamped and rolled against the wall by the four adjusting arm-abutment wheel structures. Therefore, the entire device will not become unbalanced when traveling on the wall under the clamping and coordination.

[0019] 2. Even better: Since the tilting angle of the adjusting arm can be adjusted, the wall can be clamped according to the wall thickness during actual work. Depending on the shape of the wall (longitudinal cross-section shape), by adjusting the tilting angle of the adjusting arm and the tilting angle of the abutment structure, the abutment roller on the abutment structure can be kept perpendicular to the side wall of the wall and roll.

[0020] 3. A thickened rubber sleeve is fixedly connected to the roller. The rubber sleeve is made of polytetrafluoroethylene (PTFE), which increases the friction between the roller and the top surface of the wall during rolling, further improving the stability of the mobile spray curing system.

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.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0027] Example 1: like Figure 1-6 As shown, a concrete wall spray curing device includes a walking spray curing mechanism that moves along the concrete wall. During the spray curing process, the walking spray curing mechanism not only achieves automatic spray curing but also adapts to different types of walls, such as walls with conventional rectangular, trapezoidal, or T-shaped cross-sections (mostly guardrails and retaining walls).

[0028] Specifically, the mobile spray curing mechanism includes a mobile frame 1, on which a spray water tank 2 is mounted, and the spray water tank 2 is connected to a spray pipe structure 3 for spraying water onto the wall for curing. During operation, water from the spray water tank 2 is sprayed onto the wall through the spray pipe structure 3.

[0029] To cope with different wall surfaces and ensure the device moves smoothly during operation, preventing it from falling off the wall due to imbalance, this invention makes the following improvements: It also includes several adjusting arm roller structures 4 to prevent the walking frame 1 from swaying. Specifically, one adjusting arm roller structure 4 is installed on each of the left and right sides of the front and rear ends of the walking frame 1. When the entire device is placed on top of the wall, the adjusting arm roller structures 4 clamp the wall from both sides. In the clamping and rolling state, the entire device will not be unbalanced and can walk smoothly on the wall.

[0030] The adjusting arm roller structure 4 rolls against the side walls on both sides of the wall. The adjusting arm roller structure 4 includes a fixed arm 41 fixedly installed on the traveling frame 1 (the inner end of the fixed arm 41 is welded with a mounting base, which is fastened to the side wall of the traveling frame by bolts), and an adjusting arm 42 is hinged to the fixed arm 41 (the hinge method is: the outer end of the fixed arm 41 has a hinge interface, and the top of the adjusting arm 42 is hinged in the hinge interface by a pin).

[0031] The lower end of the adjusting arm 42 is equipped with an angle-adjustable abutment structure; the adjusting arm 42 adjusts its posture by pushing the structure.

[0032] During operation, when the entire device (walking support) is placed on the wall, the four adjusting arms 42 and roller structures 4 adjust their posture. Specifically, by pushing the adjusting arms 42 towards the side wall, the abutment roller structure is pulled closer to the wall. Subsequently, the abutment roller structure adjusts its posture, causing the abutment rollers on the abutment roller structure to contact the wall in a vertical posture. The rolling direction of the abutment rollers is synchronized with the forward direction.

[0033] Under the aforementioned structural action, the adjusting arm 42 and the abutment wheel structure roll against the wall, while the two sides of the traveling bracket are clamped and rolled against the wall by the four adjusting arms 42-abutment wheel structure. Therefore, the entire device will not become unbalanced when traveling on the wall under the clamping and coordination.

[0034] Even better: Since the tilting angle of the adjusting arm 42 can be adjusted, the wall can be clamped according to the wall thickness during actual work. Depending on the shape of the wall (longitudinal cross-sectional shape), by adjusting the tilting angle of the adjusting arm 42 and the tilting angle of the abutment structure, the abutment roller on the abutment structure can be kept rolling perpendicular to the side wall of the wall.

[0035] Example 2: like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, the bottom front and rear sides of the walking frame 1 are respectively equipped with rolling structures 5 that roll on the top of the wall.

[0036] The rolling structure 5 includes a roller 51, with bearing brackets 511 rotatably connected to both ends of the roller 51. The bearing brackets 511 are fixedly installed on the walking frame 1 (specifically, a rotating shaft is fixedly connected to both ends of the roller 51, and the rotating shaft is rotatably connected to the bearing on the bearing bracket 511).

[0037] Meanwhile, to increase the friction with the wall during rolling, a thickened rubber sleeve 52 is fixedly connected to the roller. The rubber sleeve 52 is made of polytetrafluoroethylene, and it increases the friction with the top surface of the wall during rolling.

[0038] Even better, the use of rubber roller sleeve 52 is advantageous because rubber roller sleeve has a certain elasticity. When encountering obstacles such as gravel during the rolling process on the top surface of the wall, the rubber roller sleeve rolls onto the obstacle and can overcome the obstacle while ensuring stable driving through its own elastic deformation.

[0039] In the existing configuration, a motor 53 for driving the rollers is installed at the bottom rear side of the walking frame 1. The top of the motor 53 is fixedly mounted on the bracket of the bearing bracket 511 via a fixed mounting bracket.

[0040] Example 3: like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, the above-mentioned pushing structure includes an electric telescopic rod 44 hinged to the adjusting arm 42; the electric telescopic rod 44 is a conventional electric telescopic rod 44 disclosed in the prior art.

[0041] The four electric telescopic poles 44 are connected in parallel to a mobile power source using conventional electrical connection methods disclosed in the prior art (in actual operation, a lithium battery is installed on the walking frame to power components including the motor and electric telescopic poles 44, according to the existing method).

[0042] Specifically, the telescopic end of the electric telescopic rod 44 is fixedly connected to a hinge seat, and the adjusting arm 42 is fixedly connected to a pin hinged to the hinge seat. At the same time, the top of the electric telescopic rod 44 is fixedly connected to a hinge seat, and the inner side of the fixed arm 41 has a hinge opening, and the hinge seat is hinged and installed in the hinge opening by the pin.

[0043] The aforementioned abutment structure includes an abutment roller 43, and a hinge plate 431 is fixedly connected to the wheel frame of the abutment roller 43. The hinge plate 431 is hingedly installed in the hinge interface opened at the lower end of the adjusting arm 42.

[0044] To ensure that the roller 43 rolls vertically against the wall, a small motor 45 that drives the hinge plate to rotate is fixedly installed on the adjusting arm 42. Specifically, the output shaft of the small motor 45 is fixed to one side of the hinge plate (the output shaft is rotatably connected to the adjusting arm 42), while the other end of the hinge plate is rotatably connected to the adjusting arm 42 via a rotating shaft.

[0045] During operation, driven by a small motor 45, the drive roller structure flips over and rolls vertically onto the wall using the roller 43.

[0046] Example 4: like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 3, several L-shaped mounting brackets 21 are fixedly connected to the lower end of the outer side wall of the above-mentioned spray water tank 2. The mounting brackets 21 are fastened to the walking bracket by bolts.

[0047] The sprinkler pipe structure 3 includes a drain pipe 31 connected to the lower ends of the side walls of the sprinkler tank 2, and the drain pipe 31 is connected to a horizontal pipe 32. In the conventional method, several nozzles 33 are connected and installed on the horizontal pipe 32, spraying water towards the wall. The nozzles 33 are conventionally disclosed nozzles with multiple nozzle holes, and are angled downwards. During the spraying process, the water sprayed from the nozzles is directed towards the wall.

[0048] Example 5: like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 4, in order to increase the spray pressure of the nozzle during actual operation, a submersible pump (not shown in the figure) can be installed in the water tank in the existing manner, and the drain pipe 31 can be connected and installed on the outlet pipe of the submersible pump (the drain pipes 31 on both sides can be installed on the outlet pipe of the submersible pump through a T-connector).

[0049] The sprinkler pipe structure 3 is made of the same plastic material used in conventional plastic pipes to reduce load. Meanwhile, the traveling support frame is made of lightweight aluminum alloy steel. This weight reduction allows the water tank to carry more water, reducing the frequency of water replenishment.

[0050] The water tank has an open structure, which makes it easy for operators to add water to the tank.

[0051] Example 6: like Figure 1-6As shown, this embodiment, based on the structure of embodiment 5, in order to achieve intelligent spraying during actual operation, installs a camera on the walking frame 1 that can transmit monitoring images to the backend, following existing methods. Simultaneously, following existing methods, the operation can be automated by installing a PLC control circuit on the walking frame 1 to control the operation of all motors, small motors, electric telescopic poles, and submersible pumps. Using PLC to control the working components is a conventional method disclosed in existing technology.

[0052] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
