Description

Technical Field

[0001] The invention relates to the technical field of coiled material laying construction, and in particular to a laying device for a sodium-based bentonite waterproof blanket. Background Art

[0002] Bentonite, a hydrous clay mineral primarily composed of montmorillonite, is widely used in various industrial fields due to its unique properties, including swelling, adhesion, adsorption, catalysis, thixotropy, suspension, and cation exchange. Sodium bentonite is classified based on the type and content of exchangeable cations between the montmorillonite layers: sodium bentonite has a basicity coefficient greater than or equal to 1, while calcium bentonite has a basicity coefficient less than 1.

[0003] Sodium bentonite waterproof blanket is a geosynthetic material specially used for anti-seepage in artificial lake waterscape, landfill, underground garage, roof garden, pool, oil depot and chemical storage yard. It is made of highly expansive sodium bentonite filled between special composite geotextile and non-woven fabric. The bentonite anti-seepage mat is made by needle punching, which can form many small fiber spaces, so that the bentonite particles cannot flow in one direction. When it encounters water, it forms a uniform and high-density colloidal waterproof layer in the mat, which effectively prevents water leakage.

[0004] During the use of sodium bentonite waterproofing blankets, laying is a crucial task, determining whether the blanket covers all waterproofing areas. Furthermore, the smoothness and closeness of the laying process determine whether the blanket can fully function. Currently, sodium bentonite waterproofing blankets are often laid using a forklift and manual labor. This is not only labor-intensive but also prone to localized curling during laying, resulting in uneven laying. This reduces the blanket's utilization rate and can easily damage the blanket during future use. In light of this, in-depth research into these issues led to this case. Summary of the Invention

[0035] A bracket 5 is further installed on the wheel frame 2 behind the support frame 3, and a pair of traction rollers 6 arranged up and down are installed on the bracket 5.

[0036] A rectangular frame-like mounting bracket 7 is fixedly connected to the rear of bracket 5. Mounting bracket 7 has slots at each end. Driven roller 8, with cylindrical structures having external threads, is inserted into the slots and then screwed to the external threads with fixing bolts 26. A pressure roller 9 is sheathed around the outer circumference of driven roller 8. Limiting plates 29 are also provided on either side of pressure roller 9 to limit its position.

The ends of the adjustment frames 10 closer to the wheel frame 2 are rotatably connected to the wheel frame 2 via a pin 25. A traction line 11 is installed on the adjustment frame 10 and connected to the winding reel 14 via a traction ring 12. The traction line 11 passes through the traction ring 12, which is used to limit the route through which the traction line 11 passes.

[0039] The cleaning structure is arranged at the rear and lower part of the roller structure and is used to clean up debris before laying the waterproof blanket.

[0040] The cleaning structure includes a pair of rotating cleaning discs 15 , a driving rod 16 , a driven gear 17 , a rotating cylinder 18 and a driving gear 19 .

[0041] The driving gear 19 is a bevel gear that fits over the axial drive end of the traction motor 13 of the paving structure. The driven gear 17 is also a bevel gear that meshes perpendicularly with the driving gear 19. The lower end of the driven gear 17 is connected to the drive rod 16, which in turn is connected to the rotating cleaning disc 15. The cleaning disc 15 is located below the traction motor 13 on the wheel frame 2. The cleaning disc 15 consists of a plurality of rotating blades arranged in a circular array and is used to clean debris.

[0042] In addition, the cleaning structure can also include a rotating cylinder 18. The rotating cylinder 18 is sleeved on the upper periphery of the driving rod 16 for fixing the driving rod 16. A supporting spring 27 is also embedded in the rotating cylinder 18, and the top of the supporting spring 27 is connected to the bottom of the driven gear 17 through a slip ring 28.

[0043] The automatic cutting structure includes a mounting frame 20 , a rotating slot 21 , an adjusting screw rod 22 , a rotating sleeve 23 , a clamping bar 24 and a cutting knife 31 .

[0044] There is a pair of mounting frames 20, which are respectively fixedly mounted on the wheel frame 2, located behind the support frame 3 and on both sides below the pressure roller 9. A rotating motor is fixedly mounted on one side of one of the mounting frames 20, and a rotating slot 21 is provided on each mounting frame 20. The adjusting screw rod 22 is movably mounted in the rotating slot 21 and one end is connected to the driving end of the rotating motor. A rotating sleeve 23 is provided on the adjusting screw rod 22, and a cutting knife 31 is provided on the rotating sleeve 23. The cutting knife 31 is tightened and fixed to the rotating sleeve 23 by two screws; a clamping bar 24 is provided between the two mounting frames 20, and the clamping bar 24 is parallel to the pressure roller 9 and the adjusting screw rod 22. A clamping slot is provided in the center of the clamping bar 24 along the length direction, and the cutting knife 31 can be embedded in the clamping slot and slide along the clamping slot.

[0045] In the above-mentioned laying device, all electrical components are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between each electrical component is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0046] In general, the roller structure is pulled by the traction machine 1 to move in a straight line. The laying structure on the roller structure lays the waterproof blanket so that it is spread flat on the ground, and the cleaning structure removes large particles of debris before laying. The automatic cutting structure is then used to cut the material after it is laid in place.

[0047] Specifically, a waterproof blanket prepared for laying is placed on the main roller shaft 4 of the laying structure, and then the end of the waterproof blanket passes through a pair of traction rollers 6, and then passes through a pair of laying rollers 30 supported by an adjustment frame 10 after passing through a pressure roller 9 and an automatic cutting structure.

[0048] During laying, the traction motor 13 is used to rotate the reel 14 to lower the traction line 11, so that the adjustment frame 10 rotates along the pin shaft 25 so that the far end (the end with the laying roller 30) is grounded, and then the movement of the reel 14 is stopped. Then, the vehicle body is moved to cooperate with the rotation of a pair of traction rollers 6 to pull the waterproof blanket out from the main roller shaft 4, and the laying roller 30 is used for laying.

[0049] Since the pair of rotary cleaning discs 15 of the cleaning structure are arranged at the lower end of the traction motor 13 and in front of the far end of the adjustment frame 10, the rotary cleaning discs 15 in front have already cleaned the ground debris during paving.

[0050] The working principle of the cleaning structure is: the driven gear 17 on the top of a pair of driving rods 16 on the bottom surface of the wheel frame 2 is engaged with the driving gear 19 on a pair of traction motors 13, thereby rotating a pair of rotating cleaning discs 15, and the rotating cleaning discs 15 are used to clean and remove large particles of debris. The rotating cylinder 18 is used to fix the driving rod 16. At the same time, a pair of supporting springs 27 are embedded in the pair of rotating cylinders 18. The top ends of the pair of supporting springs 27 are respectively connected to the bottom ends of the pair of driven gears 17 through slip rings 28. The support springs 27 are used to support the slip rings 28 and then support the driven gear 17. The top end of the driving rod 16 passes through the support springs 27 and is connected to the driven gear 17. When the driven gear 17 rotates, the driving rod 16 rotates accordingly, and the driven gear 17 offsets part of the downward pressure due to the action of the support springs 27. At the same time, the slip ring 28 is divided into two parts, the upper part rotates with the driven gear 17, and the lower part is fixed to the support springs 27.

[0051] When the waterproof blanket is laid and needs to be cut, the rotating motor connected to one end of the adjusting screw rod 22 is started to drive the adjusting screw rod 22 to rotate, thereby engaging the adjusting screw rod 22 with the rotating sleeve 23, so that the rotating sleeve 23 mounted on the adjusting screw rod 22 moves linearly along the adjusting screw rod 22, and the cutting knife 31 fixed on the rotating sleeve 23 also moves linearly on the adjusting screw rod 22, and the waterproof blanket is cut by the cutting knife 31, and the clamping groove on the clamping bar 24 is used to guide the movement trajectory of the cutting knife 31.

[0052] To sum up, the laying device of the sodium-based bentonite waterproof blanket relies on the traction machine 1 as power to pull the laying device for linear motion, and then cooperates with the cleaning structure to clean the laying site, and then uses the laying structure to lay the waterproof blanket on the ground. After the laying is completed, it is automatically cut using the automatic cutting structure. The above structures cooperate to realize the automatic and rapid laying of the waterproof blanket, which can effectively improve the quality and efficiency of the laying of the waterproof blanket.

[0053] This document uses specific examples to illustrate the inventive concept in detail. The above embodiments are only intended to help understand the core concept of the present invention. It should be noted that any obvious modifications, equivalent substitutions, or other improvements made by a person skilled in the art without departing from the inventive concept should be included within the scope of protection of the present invention.
