Description

Technical Field

[0001] The invention belongs to the technical field of ballastless track construction equipment and relates to a laying and winding device, in particular to a geotextile laying and winding device for plate-type ballastless track construction. Background Art

[0002] As a new type of track structure with completely independent intellectual property rights in my country, CRTSIII slab track has been successfully used in the Chengguan Line, Wuhan Urban Rail Transit Railway, Shendan Line, Panying Passenger Dedicated Line, and Chengmianle Passenger Dedicated Line. The CRTSIII slab track structure consists of rails, elastic fasteners, prestressed track plates, self-compacting concrete layers, isolation layers, grooves, bases (support layers), and other parts from top to bottom.

[0003] During road maintenance and construction, laying geotextiles on the pavement structure layer is a conventional construction process. Currently, manual laying or winding is used in the laying and winding of geotextiles. After manual winding, the rolled geotextile has poor flatness and is prone to wrinkles and uneven ends, which is not conducive to the secondary laying of the geotextile and makes it difficult to achieve a smooth and uniform geotextile during the secondary laying. When laying or winding geotextiles manually, the laying personnel need to bend over or squat, which increases the labor intensity of the laying personnel and is not conducive to the movement of the laying personnel, resulting in slow winding speed and low work efficiency.

[0004] A search revealed a Chinese patent document that discloses a geotextile laying and winding device [Application Number: 201720095202.8; Publication Number: CN206503057U]. This geotextile laying and winding device includes a support platform, wheels, a first driver, a second driver, a reel, and a first guide shaft. The support platform is equipped with a third support frame and a first support frame. The third support frame supports the reel, and the first support frame supports the first guide shaft. The first driver drives the wheels to rotate, while the second driver drives the reel to rotate. The first guide shaft is lower than the reel and is closer to the front of the device body relative to the reel. This utility model automates the laying and winding of geotextiles, reducing manual labor.

[0005] The geotextile laying and rolling device disclosed in the patent can realize automatic laying and rolling of geotextiles, but the device cannot effectively prevent the geotextiles from wrinkling, which affects the secondary laying. Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a geotextile laying and winding device for slab ballastless track construction. The technical problem to be solved by the invention is: how to effectively prevent the geotextile from wrinkling.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A geotextile laying and winding device for slab ballastless track construction includes a box body, wherein the box body is fixed with a push rod through two first connecting rods, a first opening is opened on the box body, and a box cover is rotatably connected to the first opening, and two first rotating shafts are rotatably connected inside the box body, and both ends of the first rotating shafts extend out of the box body and are respectively fixed with rotating wheels, and a second rotating shaft is connected to the box body through a moving component, one of the first rotating shafts is fixed with two first gears, and the second rotating shaft is fixed with two second gears and a winding drum, the two second gears are respectively located at the two ends of the winding drum, and the second gear is meshed with the first gear, a second opening is opened on the box body, and an anti-pleat component is provided at the second opening, and the anti-pleat component is connected to the inner wall of the box body.

[0009] The working principle of the present invention is as follows: when it is necessary to lay geotextile, the box cover is opened, and then the second rotating shaft is moved by the moving assembly to disengage the second gear from the first gear, and then one end of the geotextile is extended out of the box through the second opening and fixed to the road surface, and then the box cover is closed, and then the push rod is pulled, and the push rod drives the box to move away from one end of the geotextile through the first connecting rod. Since one end of the geotextile is fixed to the road surface, the geotextile on the winding drum will be released as the box moves, and thus laid on the road surface. When it is necessary to roll up the geotextile, the box cover is opened, and one end of the geotextile is extended into the box through the second opening and fixed to the winding drum, and then the second rotating shaft is moved close to the first rotating shaft by the moving assembly, so that The second gear is engaged with the first gear, and then the box cover is closed, and then the push rod is pushed to move the box body close to the geotextile. The wheel drives the first gear to rotate through the first shaft, and the first gear drives the second shaft to rotate through the second gear. The second shaft drives the winding drum to rotate, so that the geotextile is rolled up. During the rolling process, the anti-pleat component can effectively avoid wrinkles of the geotextile and avoid affecting its secondary use. In this way, automatic laying and rolling of the geotextile can be achieved by moving the box body, which greatly reduces the labor intensity of the staff, improves the efficiency of laying and rolling, and improves the effect of laying and rolling. The structure is simple, easy to operate, easy to manufacture, and easy to maintain in the later stage, which improves the practicality and convenience of the device.

[0010] The moving assembly includes two rotating seats, which are respectively rotatably connected to the two ends of the second rotating shaft. The rotating seats are slidably connected to the inner wall of the box through a sliding groove. The rotating seats are provided with a fixed assembly, which is connected to the box.

[0011] The fixing assembly includes two baffles, a group of first grooves are provided at both ends of the slide groove, a first cavity is provided inside the rotating seat, and first blocks are slidably connected to the opposite sides of the rotating seat. One end of the first block extends into the first groove close to one end of the first gear, and the other end of the first block extends into the first cavity and is fixedly connected to the baffle. A first spring is fixed between the baffle and the inner wall of the first cavity. The first spring is sleeved on the first block, and a conical interference column is fixed to the inner wall of the first cavity through a tension spring. The conical interference column interferes with the baffle, and the other end of the conical interference column extends out of the rotating seat through a fourth connecting rod.

[0012] The tension of the tension spring is greater than the elastic force of the first spring.

[0013] When the above structure is adopted, when in use, the fourth connecting rod is pulled outward, and the fourth connecting rod drives the conical interference column to move away from the tension spring, so that the conical interference column is disengaged from the interference with the baffle. At this time, under the action of the first spring, the first block moves into the first cavity, so that the rotating seat is released, and then the rotating seat is pushed to move toward the other end of the slide groove. When the rotating seat moves to the other end of the slide groove, under the action of the tension spring, the conical interference column moves in the opposite direction, so that the conical interference column interferes with the baffle, and the first block extends into the first groove, thereby fixing the rotating seat, which makes it easy to move and fix the position of the winding drum.

[0014] The anti-pleat assembly includes two third rotating shafts, both of which are rotatably connected to the box body, and an upper pressing roller and a lower pressing roller are respectively fixed on the two third rotating shafts.

[0015] With the above structure, when in use, the geotextile is passed between the upper pressing roller and the lower pressing roller. The upper pressing roller and the lower pressing roller can effectively keep the geotextile flat to avoid affecting the secondary use.

[0016] A slope block is fixed on one side of the box away from the push rod through two second connecting rods. The slope end of the slope block faces upward, and the highest point of the slope is away from one end of the second connecting rod.

[0017] With the above structure, the setting of the inclined block can preliminarily improve the flatness of the geotextile, remove debris at the bottom of the geotextile when rolling, and keep the geotextile away from the wheel to avoid rolling and affecting the quality.

[0018] Guard plates are fixed on both ends of the winding drum.

[0019] With the above structure, the setting of the guard plate can effectively prevent the geotextile from deviating and contacting the gear when it is rolled up.

[0020] A second cavity is provided in the box cover, a second block is slidably connected to the box cover, a second groove is provided on the box body, one end of the second block extends into the second groove, and an inclined surface is provided on the second block, the other end of the second block extends into the second cavity and is fixed with a second spring, the other end of the second spring is fixedly connected to the inner wall of the second cavity, a third connecting rod is fixed on the second block, and the third connecting rod extends out of the box cover through the groove.

[0021] With the above structure, when the box lid needs to be closed, the box lid is rotated, and the inclined surface on the second block contacts the box body, causing the second block to move into the second cavity. When the second block is flush with the second groove, under the action of the second spring, the second block extends into the second groove, so that the box lid is closed and fixed. When the box lid needs to be opened, the third connecting rod is moved, and the third connecting rod drives the second block to disengage from the second groove, thereby releasing the fixation of the box lid and allowing the box lid to be rotated to open.

[0022] Compared with the existing technology, this geotextile laying and winding device for slab ballastless track construction has the following advantages:

[0023] 1. Automatic laying and rolling of geotextiles can be achieved through the mobile box, which greatly reduces the labor intensity of the staff, improves the efficiency of laying and rolling, and improves the effect of laying and rolling. The structure is simple, easy to operate, easy to manufacture, and easy to maintain in the later stage, which improves the practicality and convenience of the device.

[0024] 2. Pull the fourth connecting rod outward, and the fourth connecting rod drives the conical interference column to move away from the tension spring, so that the conical interference column is out of contact with the baffle. At this time, under the action of the first spring, the first block moves into the first cavity, so that the rotating seat is released, and then the rotating seat is pushed to move toward the other end of the slide. When the rotating seat moves to the other end of the slide, under the action of the tension spring, the conical interference column moves in the opposite direction, so that the conical interference column contacts the baffle, and the first block extends into the first groove, thereby fixing the rotating seat, which facilitates moving and fixing the position of the take-up drum.

[0025] 3. Pass the geotextile between the upper and lower pressing rollers. The upper and lower pressing rollers can effectively keep the geotextile flat to avoid affecting its secondary use.

[0026] 4. The setting of the inclined block can preliminarily improve the flatness of the geotextile, remove the debris at the bottom of the geotextile when rolling, and keep the geotextile away from the wheel to avoid rolling and affecting the quality.

[0027] 5. The setting of the guard plate can effectively prevent the geotextile from deviating and contacting the gear when rolling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0037] like Figure 1-Figure 7 As shown, the geotextile laying and winding device for slab ballastless track construction includes a box body 1, which is fixed with a push rod 3 through two first connecting rods 2. A first opening is provided on the box body 1, and a box cover 9 is rotatably connected to the first opening. Two first rotating shafts 4 are rotatably connected inside the box body 1, and both ends of the first rotating shaft 4 extend out of the box body 1 and are respectively fixed with a rotating wheel 5. A second rotating shaft 6 is connected to the box body 1 through a moving component, and two first gears 7 are fixed on one of the first rotating shafts 4, and two second gears 8 and a winding drum 10 are fixed on the second rotating shaft 6. The two second gears 8 are respectively located at both ends of the winding drum 10, and the second gear 8 is meshed with the first gear 7. A second opening is provided on the box body 1, and an anti-pleat component is provided at the second opening, and the anti-pleat component is connected to the inner wall of the box body 1.

[0038] When it is necessary to lay geotextile, open the box cover 9, and then move the second shaft 6 through the moving component to disengage the second gear 8 from the first gear 7, and then extend one end of the geotextile out of the box body 1 through the second opening and fix it to the road surface, then close the box cover 9, and then pull the push rod 3, and the push rod 3 drives the box body 1 to move away from one end of the geotextile through the first connecting rod 2. Since one end of the geotextile is fixed to the road surface, the geotextile on the winding drum 10 will be released as the box body 1 moves, and thus laid on the road surface. When it is necessary to roll up the geotextile, open the box cover 9, extend one end of the geotextile into the box body 1 through the second opening and fix it to the winding drum 10, and then move the second shaft 6 close to the first shaft 4 through the moving component, so that the second gear The wheel 8 is engaged with the first gear 7, and then the box cover 9 is closed, and then the push rod 3 is pushed to move the box body 1 close to the geotextile. The rotating wheel 5 drives the first gear 7 to rotate through the first rotating shaft 4, and the first gear 7 drives the second rotating shaft 6 to rotate through the second gear 8. The second rotating shaft 6 drives the winding drum 10 to rotate, so that the geotextile is wound. During the winding process, the anti-pleat component can effectively avoid wrinkles of the geotextile and avoid affecting its secondary use. In this way, automatic laying and winding of the geotextile can be achieved by moving the box body 1, which greatly reduces the labor intensity of the staff, improves the efficiency of laying and winding, and improves the effect of laying and winding. The structure is simple, easy to operate, easy to manufacture, and easy to maintain in the later stage, which improves the practicality and convenience of the device.

[0039] The moving assembly includes two rotating seats 11, which are rotatably connected to the two ends of the second rotating shaft 6 respectively. The rotating seats 11 are slidably connected to the inner wall of the box body 1 through the sliding groove 13. The rotating seat 11 is provided with a fixed assembly, which is connected to the box body 1.

[0040] The fixing assembly includes two baffles 14, a group of first grooves are opened at both ends of the slide groove 13, a first cavity is opened inside the rotating seat 11, and the first blocks 12 are slidably connected on the opposite sides of the rotating seat 11. One end of the first block 12 extends into the first groove close to one end of the first gear 7, and the other end of the first block 12 extends into the first cavity and is fixedly connected to the baffle 14. A first spring 15 is fixed between the baffle 14 and the inner wall of the first cavity. The first spring 15 is sleeved on the first block 12, and a conical resistance column 29 is fixed to the inner wall of the first cavity through a tension spring 17. The conical resistance column 29 resists the baffle 14, and the other end of the conical resistance column 29 extends out of the rotating seat 11 through the fourth connecting rod 30.

[0041] The tension of the tension spring 17 is greater than the elastic force of the first spring 15 .

[0042] When in use, the fourth connecting rod 30 is pulled outward, and the fourth connecting rod 30 drives the conical interference column 29 to move away from the tension spring 17, so that the conical interference column 29 is out of contact with the baffle 14. At this time, under the action of the first spring 15, the first block 12 moves into the first cavity, so that the rotating seat 11 is released, and then the rotating seat 11 is pushed to move toward the other end of the slide groove 13. When the rotating seat 11 moves to the other end of the slide groove 13, under the action of the tension spring 17, the conical interference column 29 moves in the opposite direction, so that the conical interference column 29 conflicts with the baffle 14, and the first block 12 extends into the first groove, thereby fixing the rotating seat 11, which facilitates moving and fixing the position of the winding drum 10.

[0043] The anti-pleat assembly includes two third rotating shafts 18 , both of which are rotatably connected to the box body 1 , and an upper pressing roller 22 and a lower pressing roller 23 are fixed to the two third rotating shafts 18 , respectively.

[0044] When in use, the geotextile is passed between the upper pressing roller 22 and the lower pressing roller 23. The upper pressing roller 22 and the lower pressing roller 23 can effectively keep the geotextile flat to avoid affecting its secondary use.

[0045] A slope block 20 is fixed to one side of the box body 1 away from the push rod 3 through two second connecting rods 19 . The slope end of the slope block 20 faces upward, and the highest point of the slope is away from one end of the second connecting rod 19 .

[0046] The provision of the inclined surface block 20 can preliminarily improve the flatness of the geotextile, remove debris from the bottom of the geotextile when rolling, and keep the geotextile away from the wheel 5 to avoid rolling and affecting the quality.

[0047] Guard plates 21 are fixed to both ends of the winding drum 10 .

[0048] The provision of the guard plate 21 can effectively prevent the geotextile from deviating and contacting the gears when it is rolled up.

[0049] A second cavity is provided in the box cover 9, and a second stop 25 is slidably connected to the box cover 9. A second groove is provided on the box body 1. One end of the second stop 25 extends into the second groove, and an inclined surface is provided on the second stop 25. The other end of the second stop 25 extends into the second cavity and is fixed with a second spring 27. The other end of the second spring 27 is fixedly connected to the inner wall of the second cavity. A third connecting rod 28 is fixed on the second stop 25, and the third connecting rod 28 extends out of the box cover 9 through the groove 26.

[0050] When the box cover 9 needs to be closed, the box cover 9 is rotated, and the inclined surface on the second stop 25 contacts the box body 1, causing the second stop 25 to move into the second cavity. When the second stop 25 is flush with the second groove, under the action of the second spring 27, the second stop 25 extends into the second groove, so that the box cover 9 is closed and fixed. When the box cover 9 needs to be opened, the third connecting rod 28 is moved, and the third connecting rod 28 drives the second stop 25 to disengage from the second groove, thereby releasing the fixation of the box cover 9 and allowing the box cover 9 to be rotated to open.

[0051] The working principle of the present invention is as follows: when it is necessary to lay geotextile, the third connecting rod 28 is toggled, and the third connecting rod 28 drives the second stop 25 to disengage from the second groove, thereby releasing the fixation of the box cover 9, so that the box cover 9 can be rotated to open, and then the fourth connecting rod 30 is pulled outward, and the fourth connecting rod 30 drives the conical interference column 29 to move away from the tension spring 17, so that the conical interference column 29 is disengaged from the interference with the baffle 14. At this time, under the action of the first spring 15, the first stop 12 moves into the first cavity, so that the rotating seat 11 is released, and then the rotating seat 11 is pushed to move away from the first gear 7. When the rotating seat 11 moves to the other end of the slide groove 13, then under the action of the tension spring 17, the conical contact column 29 moves in the opposite direction, so that the conical contact column 29 conflicts with the baffle 14, and the baffle 14 extends into the first groove, thereby fixing the rotating seat 11, and then passing one end of the geotextile through between the upper pressure roller 22 and the lower pressure roller 23 and extending it from the second opening, and then fixing the geotextile to the road surface, and then rotating the box cover 9, the inclined surface on the second block 25 conflicts with the box body 1, so that the second block 25 moves into the second cavity, and when the second block 25 is flush with the second groove, under the action of the second spring 27, the second block The block 25 extends into the second groove, so that the box cover 9 is closed and fixed, and then the push rod 3 is pulled, and the push rod 3 drives the box body 1 to move away from one end of the geotextile through the first connecting rod 2. Since one end of the geotextile is fixed to the road surface, the geotextile on the winding drum 10 will be released as the box body 1 moves, and thus laid on the road surface; when it is necessary to roll up the geotextile, the box cover 9 is opened, and one end of the geotextile is extended into the box body 1 through the second opening and passed between the upper pressing roller 22 and the lower pressing roller 23, and then the geotextile is fixed to the winding drum 10, and then the fourth connecting rod 30 is pulled outward and the rotating seat 11 is moved so that the rotating seat 11 is close to the first connecting rod 30. The first gear 7 moves in the direction of rotation. When the rotating seat 11 moves to the other end of the slide groove 13, the first gear 7 engages with the second gear 8. At the same time, under the action of the tension spring 17, the conical contact column 29 moves in the opposite direction, so that the conical contact column 29 conflicts with the baffle 14. The first block 12 extends into the first groove, thereby fixing the rotating seat 11. Then the box cover 9 is closed, and the push rod 3 is pushed to move the box body 1 close to the geotextile. The wheel 5 drives the first gear 7 to rotate through the first shaft 4. The first gear 7 drives the second shaft 6 to rotate through the second gear 8. The second shaft 6 drives the winding drum 10 to rotate, so that the geotextile is wound.

[0052] In summary, through the cooperation of the box 1, the rotor 5, the first gear 7 and other components, the function of effectively preventing the geotextile from wrinkling is achieved.

[0053] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
