Description

Technical Field

[0001] The invention belongs to the technical field of gravel laying for bank protection, in particular to a gravel laying device for river bank protection. Background Art

[0002] The laying of gravel for river bank protection is a protective measure for river bank soil. It can be used in conjunction with plants to build ecological slope protection to ensure the stability of the bank protection. The existing laying of gravel for river bank protection is done by first laying a gravel cushion layer and a layer of geotextile on the slope surface, and then building a shore-fixing cage on the pressed and flat cushion layer of equal thickness to fill large and small gravel fillers. Large stones are thrown into the shore-fixing cage to quickly build a frame. When the large fillers are filled to half the thickness of the shore-fixing cage, small pieces of gravel are thrown in to fill the gaps between the large stones, and then the remaining half thickness is filled. The transportation of stones on the slope is mainly manual. After the shore-fixing cage is hinged, it is difficult for equipment to assist in transportation, so manual handling and filling are required. This consumes a lot of physical energy for the staff and is inefficient.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown, the present invention provides a crushed stone laying device for river bank protection, comprising two parallel steel pipes 100, wherein the steel pipes 100 span the bank protection slope; Support seats 200 are installed at both ends of the steel pipe 100 and are respectively placed on the upper and lower slopes of the revetment; The mounting seat 300 is slidably mounted on the steel pipe 100, and the mounting seat 300 is symmetrically designed with the steel pipe 100 as a plane; A material storage box 400 is slidably mounted on the mounting seat 300 for transporting stones; The connecting ends of the steel pipe 100 and the support seat 200 are connected through a rotating mechanism, and after the two ends of the same steel pipe 100 are disconnected from the support seat 200, they can be flipped around another steel pipe 100 as an axis to the next row of cross-fixed cages.

[0020] The mounting seat 300 is slidably mounted on the steel pipe 100, and the storage box 400 is mounted on the mounting seat 300. The stone is delivered along the steel pipe 100 through each solid shore cage through the movement of the mounting seat 300, without the need for staff to carry it, which greatly simplifies the transportation process and the pressure on the staff. After the stone delivery in one row of cross solid shore cages is completed, the stone delivery of the next row of cross solid shore cages begins. The present application disassembles one of the steel pipes 100 from the support seat 200, rotates the steel pipe 100 and the mounting seat 300 around the undisassembled steel pipe 100, and flips the whole to the top of another row of solid shore cages and then fixes them. The mounting seat 300 after flipping over can still install the storage box 400 to continue the stone delivery. It is easy to adjust, and the entire revetment slope can be quickly covered step by step according to the process, unloading in the front and filling in the back. No manual handling is required, which improves efficiency and reduces the pressure on staff.

[0021] like Figure 4-Figure 6 As shown, the support seat 200 includes a pillow block square steel 201 padded on the slope, and a square steel block 204 is supported and installed on the pillow block square steel 201 through a threaded steel bar 203; A shaft sleeve 102 is installed at the end of the steel pipe 100 . The shaft sleeve 102 is fixed on a square steel block 204 through a clamp 205 . A bottom pad 206 is provided between the square steel block 204 and the shaft sleeve 102 .

[0022] The threaded steel bar 203 is used for padding, the height can be adjusted and a stable support is formed. The sleeve 102 is fixed on the steel pipe 100, and then installed on the square steel block 204 through the clamp 205 and the bottom pad 206. The steel pipe 100 can rotate around the axis, and the two fixedly connected steel pipes 100 can carry the mounting seat 300 to turn over directly.

[0023] like Figure 4 and Figure 8 As shown, a disc 202 is movably mounted on the pillow block square steel 201 , and a square steel block 204 is fixedly supported on the disc 202 by means of threaded steel 203 , and the disc 202 can freely rotate on the pillow block square steel 201 through a shaft sleeve.

[0024] The above is an implementation method of the connection between the threaded steel 203 and the pillow block square steel 201. The threaded steel 203 can rotate relative to the pillow block square steel 201 through the disc 202. When the steel pipe 100 needs to be turned over, one of the steel pipes 100 is directly disconnected from the support seat 200, and the pillow block square steel 201 is rotated to connect with the turned steel pipe 100 while turning over. The operation is simple and efficient. It can quickly adapt to the construction site environment.

[0025] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the mounting seat 300 includes two symmetrically arranged bottom plates 301, and rollers 302 are arranged on the two bottom plates 301, and the rollers 302 are rollingly installed on the steel pipe 100; The mounting base 300 further includes a discharge pipe 304 disposed in the middle and communicating with the interior of the storage box 400; The bottom plate 301 is further provided with a hanging ear 306 .

[0026] The bottom plate 301 is designed symmetrically, so that after the steel pipe 100 and the mounting seat 300 are turned over as a whole, the storage box 400 can be directly assembled on the other bottom plate 301, and then the gravel unloading and paving task can be directly carried out above the next row of cement cages. A discharge pipe 304 is arranged between the two bottom plates 301, and the discharge pipe 304 runs through the planes of the two bottom plates 301, and is used to communicate and dock with the inside of the storage box 400 assembled above the bottom plate 301, and the stone is discharged downward from the storage box 400 along the discharge pipe 304, and is discharged into the cement cage through the bottom plate 301 below.

[0027] The bottom plate 301 is provided with a hanging ear 306 for hanging ropes and cables. A worker releases the ropes and cables from above to control the mounting seat 300 to slide downward.

[0028] A valve plate is provided in the discharge pipe 304 for controlling the material discharge rate and stopping the material discharge. The valve plate in the discharge pipe 304 is controlled by rotating a handle provided on its surface.

[0029] like Figure 5 As shown, the material storage box 400 includes a box body 401 and slide rails 403 installed on both sides of the box body 401, and sliders 303 that can be slidably connected to the slide rails 403 are installed on the two bottom plates 301.

[0030] Slide rails 403 are arranged on both sides of the box 401 to cooperate with the slider 303 so that the box 401 can slide on the bottom plate 301. This design makes the box 401 easy to disassemble and assemble. The box 401 can be disassembled from the top by removing the latch and sliding directly. It can be assembled on another bottom plate 301, and can also be used to adjust the position of the box 401 on the bottom plate 301, and cooperate with the unloading notch opened on the box 401 to unload the stone downwards.

[0031] like Figure 4 As shown, the interior of the storage box 400 is evenly divided into compartments of equal volume by partitions, and a notch is opened at the bottom of each compartment. A layer of partition cloth 402 is placed at the bottom of the compartment to cover the notch and then fill it with stones.

[0032] This implementation method is used to isolate and block the discharge pipe 304 and the compartment, so as to prevent the compartment located in the middle that was originally aligned with the discharge pipe 304 from being directly connected to it and unloading during transportation. Secondly, during the sliding process of the box body 401, the internal stone is allowed to directly pass through the bottom gap of the compartment and slide in contact with the top surface of the bottom plate 301, which will cause the problem of stone jamming between the box body 401 and the bottom plate 301, resulting in poor sliding of the box body 401 and damage to the components. Therefore, a partition cloth 402 is laid at the bottom of each compartment in advance, and then crushed stones are filled in the compartment to separate the stone and the bottom plate 301. After arriving at the designated workstation, the staff will pull off the end of the partition cloth 402 that extends outward and drag the partition cloth 402 out. The stone inside the compartment can be reconnected with the discharge pipe 304, and the stone can be directly poured into the solid cage.

[0033] The partition cloth 402 is a geotextile that is redundant at the construction site or a waste cloth with a sufficient area.

[0034] The partition cloth 402 can be obtained on site and recycled without prior preparation. The redundant geotextile cut from the construction site or the discarded bags originally used to hold materials can be directly used under the condition of reaching the area, and can be folded into an appropriate shape and laid on the bottom of the partition cavity.

[0035] like Figure 1 As shown, both ends of the two steel pipes 100 are fixedly connected by a cross beam 101 .

[0036] In this embodiment, the crossbeam 101 is fixed on the steel pipe 100 to connect the two steel pipes 100, and when the laying device composed of the steel pipe 100, the mounting seat 300 and the storage box 400 is turned over, the fixed state between them is further stabilized to prevent the two steel pipes 100 from being offset and causing inconvenience in installation at the next fixing cage position. A stable rectangular structure can be formed between the steel pipe 100 and the crossbeam 101.

[0037] like Figure 8 As shown, brake mechanisms 305 are provided on both sides of the mounting seat 300 for fixing the position of the mounting seat 300 on the steel pipe 100 .

[0038] The brake mechanism 305 is used to position the laying device on the steel pipe 100 before the staff unloads the stone into the solid cage, which includes a variety of implementation methods that can be generally thought of, including bolt positioning and bayonet pins. This implementation method does not limit its specific scheme. However, the staff in the relevant field can think of that in order to achieve the purpose of stable unloading, the position of the laying device is limited by general positioning means.

[0039] like Figure 8 and Fig. 9 As shown, the brake mechanism 305 includes a brake shoe 3051 clamped on the outer periphery of the steel pipe 100, a guide rod 3052 installed between the two bottom plates 301, a spring 3053 elastically supported between the bottom plate 301 and the brake shoe 3051, a support block 3054 supported between the two brake shoes 3051, and a handle 3055 installed on the side channel steel and fixed to the support block 3054; The brake shoe 3051 is slidably mounted on the guide rod 3052 .

[0040] The above scheme is one of the implementation modes of the brake device of the laying device on the steel pipe 100 of the present application, wherein the staff located on the slope lowers the laying device from the steel pipe 100 and slides it downward to the top of the designated solid cage, and then the staff located at the designated solid cage position positions the laying device on the steel pipe 100 before starting to unload the stones, and by rotating the handles 3055 on both sides of the laying device, the brake shoe 3051 that was originally supported by the support block 3054 is closed downward again to clamp the circumference of the steel pipe 100, thereby completing the brake positioning.

[0041] The support block 3054 is an eccentric component, which can push the two support blocks 3054 apart or reduce the distance between the two support blocks 3054 when the brake shoe 3051 rotates, thereby achieving the purpose of braking. When the laying device is released and continues to go down, it is only necessary to turn the handle 3055 again to push the brake shoe 3051 apart. The operation is simple and the structure is simple and reliable.

[0042] The working principle and use process of the present invention: The mounting seat 300 is slidably mounted on the steel pipe 100, and the storage box 400 is mounted on the mounting seat 300. The stone is delivered into the steel pipe 100 through each solid cage through the movement of the mounting seat 300. After the stone delivery in one row of cross solid cages is completed, the stone delivery of the next row of cross solid cages is started. The present application disassembles one of the steel pipes 100 from the support seat 200, rotates the steel pipe 100 and the mounting seat 300 around the undisassembled steel pipe 100, and flips the whole to the top of another row of solid cages and then fixes them. The mounting seat 300 after flipping over can still be installed with the storage box 400, and the stone transportation continues.
