Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a water conservancy riverbank protection construction device and its construction method. Background Technology

[0002] Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluices, intakes, canals, ferries, rafts, and fishways, to achieve their objectives; the slope protection on both sides of a river in water conservancy projects generally requires paving construction.

[0003] Riverbank protection is an important facility for protecting river channels and preventing soil erosion. However, traditional methods of riverbank protection construction mostly rely on manual labor, which is not only inefficient but also makes it difficult to guarantee construction quality.

[0004] In the prior art, such as patent number 202310419111.5, a riverbank protection construction device includes a trough-type adaptive opening flow channel mechanism, a negative feedback residual pressure sensing mechanism, a top walking component, and a bottom walking component. To address the impact of different slopes and material flow rates on the material falling speed, this invention creatively proposes a negative feedback residual pressure sensing mechanism. This mechanism utilizes an up-and-down moving structure to move the frame, and through a pressure sensing component capable of sensing the amount of material accumulated at the bottom, it changes the friction between the fixed friction plate and the sliding friction plate, thereby adaptively adjusting the opening width of the transmission belt. After the slope and material flow rate reach the adjustment mechanism, a belt-type baffle assembly can further compensate.

[0005] For example, patent number 202010445654.0 discloses an intelligent construction equipment and method for riverbank protection in water conservancy, including a mounting frame, a hydraulic rod, a servo motor and a lead screw. The bottom side of the mounting frame is connected to the base plate through a columnar shaft. A return spring is welded and fixed to the top of the pressure plate, and the top of the return spring is welded and fixed to the lower end face of the bottom movable plate. A functional window is opened on the base plate. An eccentric wheel is welded and fixed to the bottom end of the vertical shaft, and the outer side of the eccentric wheel is in contact with the inner wall of the window. The connecting column passes through the bottom window.

[0006] The existing technology has the following problems: In the construction process, people want to simplify the construction process by integrating the pouring and wire mesh laying into one device. However, due to structural limitations, the wire mesh is difficult to fit with the concrete pouring during the laying process, causing it to drag the concrete along with it, which is difficult to meet people's needs. Based on this, it is necessary to study a water conservancy riverbank protection construction device and its construction method. Summary of the Invention

[0007] Therefore, the purpose of this invention is to provide a water conservancy riverbank protection construction device and its construction method, which effectively solves the problem that existing concrete pouring and wire mesh laying are difficult to integrate and the construction steps are cumbersome.

A roller frame is provided on the lower part of the frame, and the guide rollers are rotatably mounted on the roller frame. The side rails are fixed to the side of the frame. The movable frame has a U-shaped structure, and its upper two sides are adapted to the nested side rails through electric movable wheels. The lower part of the movable frame extends to the lower part of the frame and is fixed with a traction seat. The traction seat is provided with an inwardly facing limiting seat. The limiting seat has a limiting groove along which the wire mesh passes over the guide rollers, and its end portion is adapted to be nested in the limiting groove and fixed by fixing pins.

[0010] The concrete pouring device includes a first side plate, a second side plate, a baffle, and a connecting plate. The first side plate and the second side plate are respectively fixed in the frame by connecting rods, and a material discharge channel is formed between them. The connecting plate is connected to the end areas of the first side plate and the second side plate. The baffle is adapted to the cross-section of the material discharge channel, and its lower part extends downward and is fixed on the movable frame.

[0011] Furthermore, a rack is provided inside the side track, and an electric moving wheel is provided on the upper part of the moving frame. The electric moving wheel is a gear structure driven by a motor, and the gear structure meshes with the rack.

[0012] Furthermore, the side track includes a long side plate, a short side plate, and a bottom plate. The long side plate and the short side plate are arranged on the top of the bottom plate, with the short side plate facing outwards. A wheel frame is arranged above the moving frame, and a slot is provided on the wheel frame. The slot is adapted to fit and engage with the short side plate.

[0013] Furthermore, a limiting wheel is provided on the movable frame. The limiting wheel rests against the bottom plate and forms a corresponding limiting and locking relationship with the slot structure.

[0014] Furthermore, the frame includes a first frame, a second frame, and a connecting rod, with the connecting rod portion located in the upper end region of both frames.

[0015] Furthermore, the upper and lower walls of the limiting slot are provided with pressure rollers, and there is a pressing gap between the upper and lower pressure rollers.

[0016] Furthermore, the end of the limiting seat is provided with an open slot, the fixing pin is fixed to the wire mesh and is clamped in the slot; limiting pieces are provided above and below the fixing pin to prevent the fixing pin from coming out of the slot.

[0017] Furthermore, the upper part of the frame is provided with an anti-detachment bracket, the upper part of the limiting piece is provided with a locking post, the anti-detachment bracket is provided with an anti-detachment slot corresponding to the locking post, and a limiting shaft is inserted at the end of the anti-detachment slot.

[0018] Furthermore, the feeding channel has a structure that is larger at the top and smaller at the bottom, and the baffle is adapted to the feeding channel. The lower part of the baffle is fixed to the movable frame by a reinforcing seat.

[0019] The construction method for the water conservancy riverbank protection device includes the following steps;

[0020] Step 1: Set up the equipment

[0021] The construction site was cleared, and the upper and lower tracks were erected on the riverbed and slope. The frame, upper support, and lower support were then assembled onto the lower and upper tracks.

[0022] Step 2, Adjust the equipment

[0023] Move the mobile frame, baffle, and traction seat together to the area below the frame;

[0024] Step 3: Install the wire mesh roll

[0025] The wire mesh roll is placed on the assembly frame. The wire mesh is drawn out from the wire mesh roll, passes around the guide roller, and is clamped in the limiting slot. The wire mesh is fixed in the limiting seat by the fixing pin at the end.

[0026] Step 4: Lay the wire mesh

[0027] Start the drive motor of the mobile frame and move the mobile frame along the side track. The mobile frame will then move the wire mesh from the lower part of the riverbed upwards at an angle, so that the wire mesh is laid flat and taut at intervals above the construction area. After the laying is completed, remove the fixing pins and fix them to the ground. Fix the wire mesh from the top and determine the fixing points and the laying height of the wire mesh.

[0028] Step 5, Concrete pouring

[0029] At this time, the baffle is located above the material unloading channel, and concrete is poured from the top. Under the obstruction of the baffle, the upper area of ​​the construction area is first covered, and concrete is poured on the wire mesh at the same time. The mobile frame is gradually moved downward, and the position of the baffle is changed. Concrete is poured gradually along the direction of the material unloading channel until the lower area of ​​the frame is reached.

[0030] Step 6: Cut the wire mesh

[0031] As the mobile frame moves downward, the limiting slots apply a certain force to the wire mesh, creating tension between it and the upper fixing pins, keeping the wire mesh spaced apart and taut within the construction area; once the construction in that area is completed, the wire mesh is cut.

[0032] Step 7, move to the next construction phase.

[0033] The frame is moved to the next construction point using a moving device that connects the lower and upper rails.

[0034] The beneficial effects of the above technical solution are: the present invention is mainly used for the construction of steel wire mesh laying and concrete pouring for the protection of river slopes, integrating the two processes into one construction equipment, simplifying the construction process, improving construction efficiency, and realizing rapid construction of river channels.

[0035] In its specific structure, this invention uses a frame as a fixed base, with movable structures at both the upper and lower parts. This structure is based on existing technology but has been improved. The frame has a material unloading channel formed by a first side plate and a second side plate inside, and a side rail on the outside. The side rail is used to move the mobile frame, which can drive the traction seat and baffle to move. The movement of the baffle can change the unloading point at the end of the material unloading channel, thereby realizing the gradual unloading function. The movement of the traction seat can drag the wire mesh from the bottom to the top, realizing the flat laying operation of the wire mesh. The power for movement in the whole process comes from the power provided by the electric moving wheels of the mobile frame, which are engaged by gears and racks to achieve locking at a certain position.

[0036] During operation, the upward movement of the mobile frame in this invention is the process of laying wire mesh, and the downward movement is the process of flattening the wire rope and pouring concrete on it. At the same time, the mobile frame is moved to the lower area for the next cycle of operation. The construction process is continuous and compact, with no idle operation, resulting in high construction efficiency and improved construction efficiency.

[0037] Therefore, the present invention provides a construction device that integrates wire mesh and concrete pouring. At a single construction site, the device can be used to lay wire mesh and pour concrete. The two construction processes are interactive and reasonable, the equipment is integrated and laid out, the construction steps are simple, and the construction efficiency is high, providing people with a fast slope protection construction device.

Detailed Implementation

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0052] Example 1: This example aims to provide a water conservancy riverbank protection construction device and its construction method, mainly used for the construction of riverbank protection. In the existing construction process, wire mesh laying and concrete pouring are two separate processes. When the two are integrated into one device in the prior art, it is necessary to drag the wire mesh with concrete on it to move it, resulting in poor construction effect and failing to meet people's needs. Based on this, this example provides a water conservancy riverbank protection construction device.

[0053] like Figure 1-7 The image shows a water conservancy riverbank protection construction device, including a frame 1, an upper support 4, a lower support 2, an upper rail 5, a lower rail 3, a wire mesh laying device, and a concrete pouring device. The frame 1 is a truss structure, which is arranged in parallel above the slope. The upper support 4 and the lower support 2 are set at the upper and lower parts of the frame 1, respectively. The frame 1 is inclined and erected above the river. The lower rail 3 and the upper rail 5 are respectively set in the river and on the slope 6. The upper support 4 and the lower support 2 are respectively equipped with moving wheels adapted to the upper rail 5 and the lower rail 3. In this embodiment, the moving wheels are electric moving wheels, which enable the frame to move on the slope. The specific movement is existing technology and provides a simple translation function, which will not be described again.

[0054] The frame 1, as the main load-bearing structure, has been improved. The frame includes a first frame 9, a second frame 10, and a connecting rod 11. The connecting rod 11 is located in the upper end area of ​​the two frames. Both the first and second frames are hollow truss structures. The upper area is reinforced by the connecting rod, and the lower area is a connected material unloading channel structure.

[0055] The wire mesh laying device includes an assembly frame, a movable frame 13, a side rail 12, guide rollers 16, a traction seat 22, and fixing pins 23; the assembly frame is located at the lower part of the frame body or on the lower support, and is used to install and assemble the wire mesh roll frame 7; the assembly frame has roller seats, such as... Figure 1 The content displayed is distributed on the lower support, which holds the roller shaft of the wire mesh roll frame on the roller seat and allows it to rotate.

[0056] The side rail 12 is fixed to the side of the frame 1. The movable frame 13 has a U-shaped structure. The upper two sides of the movable frame 13 are adapted to the nested side rail 12 through electric movable wheels 20. The lower part of the movable frame 13 extends to the lower part of the frame and is fixed with a traction seat 22. A rack 124 is provided in the side rail. The upper part of the movable frame 13 is provided with electric movable wheels 20. The electric movable wheels 20 are gear structures driven by a motor. The gear structure meshes with the rack. The electric movable wheels can move on the rack by electric means, thereby changing the position of the movable frame. The lower part of the movable frame is a continuous structure and is located directly below the frame.

[0057] A roller frame 15 is provided at the lower part of the frame 1. The guide roller 16 is rotatably mounted on the roller frame 15. The roller frame structure is used to cooperate with the wire mesh 8 and adjust the extension direction of the wire mesh 8, guiding it to the traction seat below the frame 1. The traction seat 22 is provided with an inwardly facing limiting seat 14. The limiting seat 14 has a limiting groove 24. The wire mesh 8 passes around the guide roller 16, and its end portion is fitted and nested in the limiting groove 24 and fixed by a fixing pin 23.

[0058] The concrete pouring device includes a first side plate, a second side plate, a baffle, and a connecting plate 19. The first side plate and the second side plate are respectively fixed in the frame 1 by connecting rods, and a material discharge channel 17 is formed between them. The material discharge channel 17 has a structure that is larger at the top and smaller at the bottom. The connecting plate 19 connects the end areas of the first side plate and the second side plate. The baffle 18 is adapted to the cross section of the material discharge channel. Its lower part extends downward and is fixed on the movable frame. The baffle is adapted to the material discharge channel, and the lower part of the baffle is fixed on the movable frame by a reinforcing seat.

[0059] A construction method for a water conservancy riverbank protection device includes the following steps;

[0060] Step 1: Set up the equipment

[0061] The construction site was cleared, and the upper and lower tracks were erected on the riverbed and slope. The frame, upper support, and lower support were then assembled onto the lower and upper tracks.

[0062] Step 2, Adjust the equipment

[0063] Move the mobile frame, baffle, and traction seat together to the area below the frame;

[0064] Step 3: Install the wire mesh roll

[0065] The wire mesh roll is placed on the assembly frame. The wire mesh is drawn out from the wire mesh roll, passes around the guide roller, and is clamped in the limiting slot. The wire mesh is fixed in the limiting seat by the fixing pin at the end.

[0066] Step 4: Lay the wire mesh

[0067] Start the drive motor of the mobile frame and move the mobile frame along the side track. The mobile frame will then move the wire mesh from the lower part of the riverbed upwards at an angle, so that the wire mesh is laid flat and taut at intervals above the construction area. After the laying is completed, remove the fixing pins and fix them to the ground. Fix the wire mesh from the top and determine the fixing points and the laying height of the wire mesh.

[0068] Step 5, Concrete pouring

[0069] At this time, the baffle is located above the material unloading channel, and concrete is poured from the top. Under the obstruction of the baffle, the upper area of ​​the construction area is first covered, and concrete is poured on the wire mesh at the same time. The mobile frame is gradually moved downward, and the position of the baffle is changed. Concrete is poured gradually along the direction of the material unloading channel until the lower area of ​​the frame is reached.

[0070] Step 6: Cut the wire mesh

[0071] As the mobile frame moves downward, the limiting slots apply a certain force to the wire mesh, creating tension between it and the upper fixing pins, keeping the wire mesh spaced apart and taut within the construction area; once the construction in that area is completed, the wire mesh is cut.

[0072] Step 7, move to the next construction phase.

[0073] The frame is moved to the next construction point using a moving device that connects the lower and upper rails.

[0074] This embodiment uses a frame as a fixed foundation, with movable structures at both the upper and lower parts. The frame's interior has a material unloading channel formed by a first and second side plate, while the exterior has side rails. These side rails are used to move the mobile frame, enabling it to move the traction seat and baffles. The movement of the baffles changes the unloading point at the end of the material unloading channel, thus achieving a gradual unloading function. The movement of the traction seat drags the wire mesh from the bottom upwards, achieving the flat laying of the wire mesh. Throughout the process, the power for movement comes from the electric moving wheels of the mobile frame, which, through gears and racks, achieve locking at certain positions. The upward movement of the mobile frame is the process of laying the wire mesh, while the downward movement is the process of flattening the wire rope and pouring concrete on it. Simultaneously, the mobile frame is moved to the lower area for the next cycle of operation. The construction process is continuous and compact, with no idle work, resulting in high construction efficiency and improved overall construction efficiency.

[0075] Example 2 further illustrates the specific structure of the side track.

[0076] like Figure 12As shown in Embodiment 1, the side rail 12 structure is set on both sides of the frame 1 and serves as the moving base of the mobile frame. In this embodiment, the side rail 12 includes a long side plate 122, a short side plate 123, and a bottom plate 121. The long side plate 122 and the short side plate 123 are arranged above the bottom plate 121, with the short side plate 123 facing outwards. A wheel frame 21 is arranged above the mobile frame 13, and a slot 125 is provided on the wheel frame 21. The slot 125 is adapted to and engages with the short side plate 123. The slot 125 structure can limit the horizontal position of the mobile frame, so that it can always move stably on the side rail 12. At the same time, the short side plate 123 can avoid the frame structure of the electric moving wheel 20.

[0077] Meanwhile, in this embodiment, a limiting wheel 126 is provided on the mobile frame. The limiting wheel 126 rests against the bottom plate and forms a corresponding limiting and locking relationship with the slot structure, thereby limiting vertically from the bottom. Combined with the slot structure, it ensures the stable operation of the mobile frame.

[0078] Example 3 further illustrates the traction structure of the wire mesh.

[0079] like Figure 11 As shown in the figure, in this embodiment, the wire mesh 8 is pulled by the moving frame 13 and the limiting seat 14. The end of the limiting seat 14 is provided with an open slot. The fixing pin 23 is fixed on the wire mesh 8 and is clamped in the slot. It will not come out when dragged upward, and the fixing pin 23 can be easily removed from the top. The fixing pin 23 is provided with limiting pieces 25 at the top and bottom to prevent the fixing pin 23 from coming out of the slot.

[0080] The upper part of the frame 1 is provided with an anti-detachment bracket 27, and the upper part of the limiting piece 25 is provided with a locking post 26. The locking post 26 corresponds to the anti-detachment bracket and is fitted inside the anti-detachment bracket. The anti-detachment bracket is provided with an anti-detachment groove corresponding to the locking post. The end of the anti-detachment groove is limited by an insertable limiting shaft, so that when the locking post is inserted into the anti-detachment groove, it can be limited, realizing the separation of the fixing pin and the groove.

[0081] To facilitate movement, pressure rollers 30 are provided on the upper and lower walls of the limiting slot in this embodiment. There is a clamping gap between the upper and lower pressure rollers, which is used to generate a small drag force when moving downward, so as to provide a certain force for the straightening of the wire mesh. This process is mainly reflected in the downward movement process.
