Description

Technical Field

[0001] The invention relates to the field of laying geotextiles in parks, and more particularly to a geotextile rolling bracket. Background Art

[0002] Geotextile is a synthetic fiber fabric with good permeability, filtration, isolation, reinforcement and corrosion resistance. It is widely used in civil engineering, water conservancy engineering, environmental engineering and other fields.

[0003] When laying geotextiles in parks, geotextile brackets are often used to assist in laying. The manual pulling method is more convenient than laying geotextiles with large geotextile rolling brackets. Large geotextile rolling brackets are not convenient for laying in parks due to the corners of parks. The manual geotextile rolling bracket method is more convenient and can take care of all corners and bends.

[0004] However, manual laying will cause the support part of the geotextile bracket to be offset from the surface of the geotextile due to the terrain. When the geotextile rolling bracket is operating on a terrain with a large slope, there will be errors in laying due to the lack of reference objects. If the error is too large when laying the geotextile, it will cause the geotextile to be laid unevenly, the edges of the geotextile will not be straight, but crooked, affecting the subsequent work of the geotextile joints.

[0005] For this purpose, a geotextile rolling bracket is proposed. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present application provides a bracket body, a roller, a traction rope, a towing box, a cloth pressing assembly, a cloth pulling assembly and an offset assembly. The construction personnel at the bracket body only need to ensure that the offset assembly checks whether the offset value is within the normal error range. Even on a terrain with a large slope, the rope offset position is kept within the normal range of the error groove.

[0021] (3) This application sets a hydraulic trough, an extrusion block, a slider, a prompt rod and a comparison block. When the offset exceeds the normal error range, it is only necessary to determine the specific position of the prompt rod on the surface of the comparison block, and then to know the offset by coordinating the scale on the surface of the comparison block. By roughly calculating the distance forward, it is possible to know which part of the geotextile is crooked, which can facilitate construction personnel to make timely adjustments to the geotextile with laying problems, further ensuring the neatness of the laid geotextile;

[0022] (4) The present application sets a pigment trough, a material injection tube and a positioning wheel, so that the positioning wheel can mark the path with pigment while rotating in cooperation with the material discharge hole, thereby marking the path for laying the geotextile, making it easier for construction personnel to determine whether the path for laying the geotextile is straight, and further facilitating the construction personnel to adjust the position of the geotextile after distortion.

[0037] The offset assembly 8 includes an offset block 88 fixedly mounted on the bracket body 1, a reserved groove 81 is provided inside the offset block 88, two sliders 82 are slidably arranged in the reserved groove 81, and the two sliders 82 are symmetrically arranged, a bucket-shaped opening is provided between the two sliders 82, the bucket-shaped opening is an error groove 83, and the traction rope 4 passes through the bucket-shaped opening.

[0038] The rope reel 3 includes a rope winding ring 31 fixedly mounted on each bracket body 1, and a rope groove 33 is opened in the rope winding ring 31, a wire winding spring 32 is arranged in the rope groove 33, a columnar protrusion is arranged in the central part of the rope winding ring 31, and the inner circle of the wire winding spring 32 is fixedly connected to the columnar protrusion, and the outer circle of the wire winding spring 32 is fixedly connected to the traction rope 4, and the wire winding spring 32 expands by pulling the traction rope 4, and a cover plate 34 is clamped on the rope winding ring 31 to prevent dust from entering the rope groove 33.

[0039] The cloth pressing assembly 6 includes a downward pressing rotating rod 61 fixedly connected to the outer surface of the drag box 5, the outer surface of the downward pressing rotating rod 61 is fixedly connected to the downward pressing coil spring 62, and the outer ring fixed sleeve of the downward pressing coil spring 62 is provided with a ring 63, the downward pressing rotating rod 61 is rotatably connected to the center of the ring 63, and a connecting rod 64 is welded on the outer surface of the ring 63, and the end of the connecting rod 64 away from the ring 63 is fixedly connected to the pressing roller shaft 65, and the pressing roller shaft 65 is rotatably connected to the cloth pressing roller 66 used to flatten the geotextile.

[0040] The cloth pulling assembly 7 includes a cloth pulling connecting rod 72 rotatably installed on both sides of the drag box 5. The outer surfaces of the two cloth pulling connecting rods 72 are welded with manually controlled hand levers 71. One end of the two cloth pulling connecting rods 72 extends to the interior of the drag box 5 and is fixedly connected to the same roller 73. The outer surface of the roller 73 is provided with a row of fixing needles 74 for fixing the geotextile.

[0041] When laying the geotextile, first place the bracket body 1 on the soil foundation, align the edge of the bracket body 1 with the edge of the geotextile, then fix the left bracket body 1 (a pin can be inserted into the soil, etc.), put the cylindrical geotextile on the outer surface of the drum 2, then insert the other bracket body 1 into the drum 2 through the insertion rod 11, align the edge of the right bracket body 1 with the edge of the geotextile, fix the right bracket body 1, then place the drag box 5 at the position where the geotextile needs to be laid, pull out the traction rope 4, and tie the traction rope 4 to the drag box 5. At this time, the traction rope 4 is in a taut state. By adjusting the position of the drag box 5, the traction rope 4 on the drag box 5 and the traction rope 4 pulled out from the rope reel 3 are on the same vertical plane. At this time, manually pull out and extend the geotextile, pass through the cloth pressing assembly 6 to the bottom of the cloth pulling assembly 7, and manually extend the geotextile. One end is fixed on the cloth pulling assembly 7, and then the towing box 5 is moved. The construction worker pulling the towing box 5 needs to ensure that the towing rope 4 on the towing box 5 and the towing rope 4 pulled out of the rope reel 3 are on the same vertical plane. At the same time, the construction worker at the position of the bracket body 1 needs to check whether the offset value is within the normal error range through the offset assembly 8 on the bracket body 1. If the offset exceeds the normal error range, the construction worker pulling the towing box 5 needs to be reminded to adjust the direction of laying the geotextile. Even on a terrain with a large slope, it is only necessary to fix the bracket body 1 and keep the rope offset position within the normal range of the error groove 83. This is more accurate than the conventional two construction workers visually checking whether the geotextile is laid neatly, and can effectively reduce the error caused by laying the geotextile, so that the edge of the geotextile remains straight, which is convenient for subsequent geotextile seam operations.

[0042] When the cloth pressing assembly 6 is working, the extended end of the geotextile is manually pulled through the cloth pressing roller 66 to the bottom of the cloth pulling assembly 6. Because the inner ring of the downward pressure coil spring 62 is fixedly connected to the downward pressure rotating rod 61 fixed on the drag box 5, and the outer ring of the downward pressure coil spring 62 is fixedly connected to the sleeve ring 63, the geotextile is passed from under the cloth pressing roller 66. Due to the thickness of the geotextile itself, the cloth pressing roller 66 will be slightly lifted, and the cloth pressing roller 66 will make the geotextile pass through the pressure roller shaft 65 and the connecting rod 64. Figure 7 The ring 63 in the middle rotates counterclockwise, thereby putting the downward pressure coil spring 62 in a stretched state, and at the same time pressing the coil spring 62 itself downward, so that Figure 7 The middle and lower pressure coil spring 62 will tend to rotate clockwise. Figure 7 The downward pressing coil spring 62 with a counterclockwise rotation tendency will transmit this tendency to the cloth pressing roller 66 through the collar 63, the connecting rod 64 and the pressing roller shaft 65, and then the cloth pressing roller 66 will press down the geotextile below, so that the entire cloth pressing assembly 6 can press down the geotextile, so that the geotextile is closely attached to the foundation soil;

[0043] When the geotextile is manually pulled to the position directly below the transfer roller 73 of the fabric pulling assembly 7, the fabric pulling assembly 7 needs to be manually started. First, the construction worker pulling the towing box 5 manually bends the hand lever 71 to move the geotextile. Figure 7 The middle hand lever 71 should be moved clockwise. When the hand lever 71 is moved clockwise, the roller 73 coaxially rotating with the cloth pulling link 72 will also rotate clockwise. When the roller 73 rotates clockwise, the fixing pin 74 on the surface of the roller 73 rotates counterclockwise from top to bottom, and the fixing pin 74 contacts the geotextile and pierces into the geotextile to roll it up. As the fixing pin 74 rotates, the extended end of the geotextile will be fixed on the roller 73, thereby achieving the effect of fixing the geotextile.

[0044] When using the offset component 8 to judge whether the geotextile is laid flat, the construction personnel at the bracket body 1 only need to observe whether the traction rope 4 passing through the slider 82 contacts the inner wall of the bucket-shaped error groove 83 to determine whether it is within the normal range of the offset value. If it contacts the inner wall on the left side of the error groove 83, the construction personnel pulling the tow box 5 need to be reminded to adjust the position slightly to the right. If it contacts the inside of the right side of the error groove 83, the construction personnel pulling the tow box 5 need to be reminded to adjust the position slightly to the left.

[0045] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, each bracket body 1 is provided with a mounting hole 12 for fixing the bracket body 1 , and each bracket body 1 is provided with a plurality of universal grooves 13 inside, and a ball 14 made of hard rubber is rotatably arranged in each universal groove 13 .

[0046] When fixing the bracket body 1, first align the edge of the bracket body 1 with the edge of the geotextile. If it is not aligned, the bracket body 1 can be pushed to move slightly. Since the ball 14 can rotate in the universal groove 13, the position of the bracket body 1 can be moved more easily. At the same time, since the part of the ball 14 protruding from the universal groove 13 is equivalent to a protrusion, the edge of the fixed bracket body 1 is aligned with the edge of the geotextile. When the pin passes through the mounting hole 12 to fix the bracket body 1, the bracket body 1 as a whole is subjected to the downward force when the bracket body 1 is fixed by the pin. The bracket body 1 will be close to the geotextile. At this time, the ball 14 equivalent to the protrusion can fix the geotextile. Since the bracket body 1 is subjected to the downward force The force generated by the geotextile 11 and the universal groove 13 increases, and the pressure between the surface of the ball 14 and the universal groove 13 increases, preventing the ball 14 from rotating, so that the bracket body 1 can be more firmly fixed on the surface of the geotextile. Even if the drag box 5 stretches and extends the geotextile to generate a larger stretching force, the geotextile will not be easily moved (because the pins are inserted into the soil through the geotextile. If the geotextile is subjected to tension at this time, the part of the geotextile passed by the pins will be damaged, and the force-bearing capacity here will deteriorate. If the geotextile is not fixed by the bottom of the bracket body 1, it will be torn, causing the geotextile to deviate). This further improves the neatness of laying the geotextile and effectively reduces the occurrence of the geotextile being deviated due to excessive force in the extension direction during laying.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure cloth pressing assembly 6 and Figure 8 As shown, an L-shaped hydraulic groove 84 is opened inside the offset block 88, and an extrusion block 85 is slidably and sealedly installed inside the hydraulic groove 84, and the extrusion block 85 is fixedly installed on the outer surface of the slider 82. One end of the hydraulic groove 84 extends upward to the outer surface of the offset block 88, and a scaled comparison block 86 is fixedly installed on the top of the outer surface of the offset block 88. A prompt rod 87 is slidably arranged inside the upwardly extending part of the hydraulic groove 84.

[0048] When the traction rope 4 has contacted the inner wall of the error groove 83 and the slider 82 has moved in the reserved groove 81, it is not convenient to judge how much the normal error range is exceeded at this time and where the position of the geotextile needs to be adjusted. If the traction rope 4 deviates to the left, it is only necessary to observe the bracket body 1 on the left. The traction rope 4 deviates to the left, which will squeeze the inner wall on the left side of the error groove 83, and then squeeze and push the slider 82 to move to the left. When the slider 82 moves to the left, the extrusion block 85 fixed on the slider 82 will extend into the hydraulic groove 84 and squeeze the liquid in the hydraulic groove 84 (the hydraulic groove 84 is filled with vegetable oil and can ensure that the top of the prompt rod 87 is aligned with the offset The outer surface of the top of block 88 is in the same horizontal plane. It should be noted here that the liquid filled in the hydraulic tank 84 includes vegetable oil, hydraulic oil and other liquids that can be used as hydraulic materials but is not limited to vegetable oil). The liquid is squeezed and moves in the hydraulic tank 84 and pushes the prompt rod 87 to move upward. At this time, it is only necessary to determine whether the prompt rod 87 is located at the scale on the surface of the comparison block 86 to know the offset. By roughly calculating the distance forward, it can be known which part of the geotextile is crooked. The construction personnel pulling the tow box 5 can make timely adjustments, which further improves the neatness of the geotextile laying and corrects the crooked part of the geotextile in time.

[0049] like Figure 1 , Figure 4 and Figure 7 As shown, a group of hooks 51 are fixedly installed on the towing box 5, and the traction rope 4 is tied to the hooks 51. The traction rope 4 is always in a taut state when it is pulled out of the rope reel 3.

[0050] Since the traction rope 4 is tied to the hook 51 on the towing box 5, the equipment can be divided into multiple parts by untying the traction rope 4 during transportation, which is convenient for movement and suitable for terrains of different terrains. It is more convenient to use and carry, and the traction rope 4 is always in a taut state, which can make it easier to judge whether the geotextile is offset when laying the geotextile.

[0051] like Figure 1 , Figure 4 , Fig. 9 and Fig.10As shown, two door panels 52 are hinged on the towing box 5. The door panels 52 are opened to expose a pigment groove 55 opened inside the towing box 5. A positioning assembly 9 for assisting in laying geotextile is arranged at the bottom edge of the towing box 5. A brake wheel 54 is also arranged at the bottom of the towing box 5. A hand-holdable handle 53 is fixedly installed on the same side of the outer surface of the towing box 5 and the door panel 52. The positioning assembly 9 includes a fixed block 92 fixedly installed at the bottom of the outer surface of the towing box 5. A hollow positioning wheel 91 is arranged between the fixed blocks 92. A wheel axle 93 is arranged between the positioning wheel 91 and the fixed block 92. The positioning wheel 91 rotates on the fixed block 92 through the wheel axle 93. A plurality of discharge holes 94 communicating with the outside are equidistantly arranged on the circumference of the positioning wheel 91. A material injection pipe 95 is connected to one side of the positioning wheel 91. The material injection pipe 95 is located at the center of the positioning wheel 91, and one end of the material injection pipe 95 extends to the inside of the pigment groove 55 and communicates with the pigment groove 55.

[0052] The width between the outermost sides of the two positioning wheels 91 is the same as the length of the drum 2 .

[0053] Before moving the tow box 5, open the door panel 52 hinged to the tow box 5, and pour paint into the paint tank 55 (it should be noted here that the paint can be white powder or a conspicuous powder material for construction to serve as a reminder). The paint in the paint tank 55 enters the hollow positioning wheel 91 inside through the injection pipe 95. Then the construction worker holds the handle 53 with both hands and moves the tow box 5. When the tow box 5 moves, the positioning wheel 91 rotates, and the positioning wheel 91 will press on the geotextile and leave marks on the geotextile. When the positioning wheel 91 rotates, the powder pigment inside the positioning wheel 91 will flow out through the discharge hole 94 on the surface and fall on the The traces left by the positioning wheel 91 on the geotextile make it convenient for construction workers to see through the paint whether the path of laying the geotextile is straight. The traces left by the positioning wheel 91 make it convenient for one piece of geotextile to be laid to the end. Another piece of geotextile needs to be laid next to it for jointing. The part pressed into the soil by the positioning wheel 91 here can be positioned. The edge of the other geotextile is aligned with the trace pressed by the positioning wheel 91. At this time, the right positioning wheel 91 is aligned with the left positioning wheel 91 corresponding to the previously pressed trace. The edges of the two geotextiles are pressed by the positioning wheel 91, the joints are tighter, and no gaps will appear, further improving the ease of jointing when laying the geotextile.

[0054] Instructions for use: When the present invention is in use, the bracket body 1 is placed on the soil foundation, the edge of the bracket body 1 is aligned with the edge of the geotextile, the bracket body 1, the roller 2 and the tubular geotextile are installed, and then the drag box 5 is placed on the side where the geotextile needs to be laid, the traction rope 4 in the rope reel 3 is pulled out, the traction rope 4 is tied to the drag box 5, and the position of the drag box 5 is adjusted so that the traction rope 4, the drag box 5 and the bracket body 1 are located on the same vertical plane. At this time, the geotextile is manually pulled out and extended, passing through the cloth pressing assembly 6 until the geotextile is extended to the bottom of the cloth pulling assembly 7, and the cloth pulling assembly 7 is manually used to fix the extended end of the geotextile on the cloth pulling assembly 7. At this time, the drag box 5 can be pulled to move The construction workers pulling the tow box 5 only need to ensure that the traction rope 4 pulled out from the rope reel 3 is in a straight line. At the same time, the construction workers on the side of the bracket body 1 can also check whether the offset value is within the normal error range through the offset component 8 on the bracket body 1, thereby reminding the construction workers pulling the tow box 5 to adjust the direction. Even on a terrain with a large slope, it is only necessary to fix the bracket body 1 and keep the rope offset position within the normal range of the error groove 83. This is more accurate than the conventional two construction workers visually checking whether the geotextile is laid neatly, and can effectively reduce the error caused by laying the geotextile, so that the edge of the geotextile remains straight, which is convenient for subsequent geotextile seam operations.

[0055] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
