Description

Technical Field

[0001] The present invention relates to the technical field of road construction, in particular to a fully automatic laying and recycling device for a base layer health-preserving geotextile. Background Art

[0002] The geotextiles used to maintain a water-stable subbase are typically permeable. Their primary functions are: 1. Isolation: preventing the mixing and loss of two or more soil types, maintaining the overall structure, and increasing the foundation's bearing capacity. 2. Filtering: Permeable and breathable. The properties of water effectively prevent the fall of particulate matter, increasing project stability. 3. Water-conducting: They create drainage channels in the soil layer to remove excess liquid and gas. This is crucial for the construction of roads with a water-stable subbase. Paving is typically done by workers rolling the material forward, adjusting it as they go to ensure a smooth surface. The midsection can be stitched, but it's important to note that the overlap should be at least 10 centimeters to ensure a more secure structure.

[0003] Currently, the water-stable base layer is mostly paved by manually rolling the cured geotextile. Its paving efficiency is low and the paving speed is slow, which affects the construction period of the road foundation. Therefore, it is particularly important to propose a fully automatic paving and recycling device for the base curing geotextile with efficient paving and recycling while reducing labor input costs. In view of this, we propose a fully automatic paving and recycling device for the base curing geotextile. Summary of the Invention

[0005] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is: to design a fully automatic laying and recycling device for base health geotextile, including a driving carrier, a connecting frame, a driving mechanism, a winding shaft, a driven mechanism, an opposing screw rod, a one-way structure and a folding structure; the connecting frame is arranged on the movable end of the driving carrier; the driving mechanism is arranged on a mounting platform on one side of the connecting frame; the winding shaft is arranged on the mounting platform on the other side of the connecting frame through a bearing seat and connected to the driving mechanism; the driven mechanism is arranged at one end of the winding shaft and connected to the driving mechanism; the opposing screw rod is arranged on the connecting frame through a bearing; the one-way structure is arranged at one end of the opposing screw rod and connected to the driven mechanism; wherein the gap between the opposing screw rod and the winding shaft constitutes a folding cavity; the folding structure is arranged on the connecting frame and connected to the folding cavity through a mounting frame; wherein, the driving carrier, connecting frame, driving mechanism, winding shaft, driven mechanism, opposing screw rod, one-way structure and folding structure constitute a movable laying and winding structure. The present invention can directly wind the geotextile onto the reel by mechanical means through the reel and the driving mechanism. At the same time, it can be driven on the water-stable base layer of the road under construction in conjunction with the driving vehicle. The geotextile can be rolled up by the relative reverse driving rotation of the driving mechanism and the change of the driving direction of the driving vehicle. This method effectively improves the laying and recycling efficiency of the geotextile, effectively shortens the construction time, and reduces the construction period.

[0006] Preferably, the driving mechanism includes a servo motor, a driving gear, a rotating shaft seat, a driven gear, and a driving chain; the servo motor is arranged on a mounting platform on one side of the connecting frame; the driving gear is arranged at the driving end of the servo motor; the rotating shaft seat is arranged on one side of the servo motor; the driven gear is arranged at one end of the winding shaft and connected to the rotating shaft seat; the driving chain is sequentially sleeved on the driving gear and the driven gear; wherein the servo motor, the driving gear, the rotating shaft seat, the driven gear, and the driving chain constitute an engaged transmission structure. The present invention realizes the laying and recycling operations of the device by synchronously driving the driven gear and the winding shaft to rotate relatively adapted to each other through the forward or reverse rotation of the servo motor.

[0007] Preferably, the driven mechanism includes an auxiliary gear and a driven chain; the auxiliary gear is arranged on one side of the driven gear and connected to the winding shaft; and the driven chain is arranged on the auxiliary gear. The present invention, through the arrangement of the auxiliary gear and the driven chain, combined with the arrangement of the one-way structure, can synchronously and adaptively rotate the opposing screws during the winding process.

[0008] Preferably, the one-way structure causes an inner sleeve, an engagement block, a spring and an outer engagement toothed disc; the inner sleeve is arranged on the opposing screw rod near one end of the driven chain; a number of the engagement blocks are hinged to the outer wall of the inner sleeve in an annular shape with equal spacing; the spring is arranged on the inner corner surface of the engagement block to connect the inner sleeve; wherein, the engagement block is elastically connected to the inner sleeve through a spring; the outer engagement toothed disc is arranged outside the inner sleeve; and the inner wall of the outer engagement toothed disc is annular with engagement grooves distributed at equal spacing; wherein, the engagement groove is an acute angle structure. The present invention hinges the engagement block and the inner sleeve, and under the elastic action of the spring, the engagement block and the engagement groove are engaged, so that the outer engagement toothed disc cannot rotate synchronously with the inner sleeve during the unwinding operation, so that the opposing screw rod remains in a stopped state, and the rotation of the opposing screw rod is prevented from causing wrinkles and stacking of the geotextile.

[0009] Preferably, the outer surface of the opposing screws is provided with two symmetrically distributed spiral protrusions. The present invention uses the two symmetrically distributed spiral protrusions to cause the opposing screws to rotate synchronously during the winding process. The rotation of the spiral protrusions is used to cause the rolled geotextile to be spread out flat, effectively avoiding wrinkles and stacking during the winding process. At the same time, it provides an auxiliary outward force for the operation of folding the geotextile in the folding structure, facilitating stable folding and winding operations.

[0010] Preferably, the folding structure includes a horizontal frame and a folding pipe; at least one of the horizontal frames is bolted to the connecting frame mounting frame; and the folding pipe is arranged in an inclined structure at the end of the horizontal frame. The bolt arrangement of the present invention allows workers to easily install and remove the horizontal frame and folding pipe, adapting to the laying work and folding work during the winding process.

[0011] Preferably, the folding pipe is composed of a folding portion and an expansion portion; the internal gap of the folding portion constitutes a "C"-shaped cavity, and a limiting plate is provided inside the folding portion, wherein the limiting plate extends into the expansion portion, and the expansion portion is large at one end and small at the other end. The present invention sets a "C"-shaped cavity, and with the preliminary manual assistance and the auxiliary outward force provided by the opposing screw rod, the edge of one side of the geotextile can be partially folded in half during the winding process. Conventional geotextiles are white or light-colored and laid on another set of geotextiles so that the overlapping part exceeds 10CM. The color of the geotextile and the color of the road are used, and by folding in half, the folded geotextile can be driven directly along the edge of another geotextile on a road with a larger width. The color difference is used to reduce the direct overlap during the laying process, reduce the situation where the driving vehicle has too few overlapping parts due to visual differences and lack of operating experience, and provide intuitive visual assistance to the operator to improve the operating accuracy.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention can mechanically wind the geotextile directly onto the reel through the reel and the driving mechanism. At the same time, it can be driven on the water-stable base layer of the road under construction in conjunction with the driving vehicle. The geotextile can be rolled up by the relative reverse driving rotation of the driving mechanism and the change of the driving direction of the driving vehicle. This method effectively improves the laying and recycling efficiency of the geotextile, effectively shortens the construction time and reduces the construction period.

[0014] 2. The present invention drives the driving gear through the forward or reverse rotation of the servo motor to synchronously drive the driven gear and the winding shaft to perform relatively adaptive rotation, thereby realizing the laying and recycling operations of the device.

[0015] 3. The present invention hinges the engaging block and the inner sleeve, and under the elastic action of the spring, the engaging block and the engaging groove are engaged, so that the inner sleeve of the outer engaging gear disc cannot rotate synchronously during the unwinding operation, so that the opposing screw rod remains in a stopped state, avoiding the situation where the geotextile is wrinkled and stacked due to the rotation of the opposing screw rod.

[0016] 4. The present invention arranges two symmetrically distributed spiral protrusions, causing the opposing screws to rotate synchronously during the winding process, and utilizes the rotation of the spiral protrusions to cause the rolled geotextile to spread out flat, effectively avoiding the situation of wrinkles and stacking during the winding process, and at the same time providing auxiliary outward force for the operation of the folding geotextile with a folding structure, thereby facilitating stable folding and winding operations.

[0017] 5. The present invention sets a "C"-shaped cavity, and with the initial manual assistance and the auxiliary outward force provided by the opposing screw, one edge of the geotextile can be partially folded in half during the winding process. Conventional geotextiles are white or light-colored and laid on another set of geotextiles so that the overlapping part exceeds 10CM. The color of the geotextile and the color of the road are matched, and by folding in half, the folded geotextile can be driven directly along the edge of another geotextile on a road with a wider width.

[0030] The present application is further illustrated below in conjunction with the accompanying drawings and examples:

[0031] Example 1: A full-automatic laying and recycling device for base maintenance geotextile, see Figures 1 to 6, including a driving carrier 1, a connecting frame 2, a driving mechanism 3, a winding shaft 4, a driven mechanism 5, an opposing screw rod 6, a one-way structure 7 and a folding structure 8; the connecting frame 2 is arranged on the movable end of the driving carrier 1; the driving mechanism 3 is arranged on the mounting platform on one side of the connecting frame 2; the winding shaft 4 is arranged on the mounting platform on the other side of the connecting frame 2 and connected to the driving mechanism 3; the driven mechanism 5 is arranged at one end of the winding shaft 4 and connected to the driving mechanism 3; the opposing screw rod 6 is arranged on the connecting frame 2 through a bearing; the one-way structure 7 is arranged at one end of the opposing screw rod 6 and connected to the driven mechanism 5; wherein, the gap between the opposing screw rod 6 and the winding shaft 4 constitutes a folding cavity; the folding structure 8 is arranged on the connecting frame 2 and connected to the folding cavity through the mounting frame; wherein, the driving carrier 1, the connecting frame 2, the driving mechanism 3, the winding shaft 4, the driven mechanism 5, the opposing screw rod 6, the one-way structure 7 and the folding structure 8 constitute a movable laying and winding structure. The present invention can mechanically wind the geotextile directly onto the winding shaft 4 through the winding shaft 4 and the driving mechanism 3. At the same time, it can be driven by the driving vehicle 1 to travel on the water-stable base layer of the road under construction. The geotextile can be rolled up by the relative reverse driving rotation of the driving mechanism 3 and the change of the driving direction of the driving vehicle 1. This method effectively improves the laying and recycling efficiency of the geotextile, effectively shortens the construction time, and reduces the construction period.

[0032] Specifically, the driving mechanism 3 includes a servo motor 301, a driving gear 302, a rotating shaft seat 303, a driven gear 304, and a driving chain 305; the servo motor 301 is arranged on a mounting platform on one side of the connecting frame 2; the driving gear 302 is arranged at the driving end of the servo motor 301; the rotating shaft seat 303 is arranged on one side of the servo motor 301; the driven gear 304 is arranged at one end of the reel 4 and connected to the rotating shaft seat 303; the driving chain 305 is sequentially sleeved on the driving gear 302 and the driven gear 304; wherein, the servo motor 301, the driving gear 302, the rotating shaft seat 303, the driven gear 304, and the driving chain 305 constitute an engaged transmission structure. The present invention drives the driving gear 302 by the forward or reverse rotation of the servo motor 301 to synchronously drive the driven gear 304 and the reel 4 to rotate relatively adapted to each other, thereby realizing the laying and recycling operations of the device.

[0033] Furthermore, the driven mechanism 5 includes an auxiliary gear 501 and a driven chain 502; the auxiliary gear 501 is arranged on one side of the driven gear 304 and connected to the reel shaft 4; the driven chain 502 is arranged on the auxiliary gear 501. The present invention, through the arrangement of the auxiliary gear 501 and the driven chain 502, in conjunction with the arrangement of the one-way structure 7, can synchronously and adaptively rotate the opposing screw rod 6 during the reeling process.

[0034] Further, the one-way structure 7 causes the inner sleeve 701, the engaging blocks 702, the springs 703 and the outer engaging tooth disc 704; the inner sleeve 701 is arranged at the end of the opposite screw rod 6 close to the driven chain 502; a plurality of engaging blocks 702 are annularly and equidistantly hinged to the outer wall of the inner sleeve 701; the spring 703 is arranged at the inner sleeve 701 connected to the inner sleeve 701 through the spring 703; the outer engaging tooth disc 704 is arranged outside the inner sleeve 701; and the inner wall of the outer engaging tooth disc 704 is annularly and equidistantly distributed with engaging grooves 7041; wherein the engaging grooves 7041 are acute angle structures. The engaging blocks 702 are hinged to the inner sleeve 701, and under the elastic action of the spring 703, the engaging blocks 702 and the engaging grooves 7041 are clamped, so that the outer engaging tooth disc 704 cannot rotate synchronously with the inner sleeve 701 during unwinding, so that the opposite screw rod 6 remains in a stopped state, avoiding the situation that the rotation of the opposite screw rod 6 causes the geotextile to be wrinkled and stacked.

[0035] It is worth noting that the outer surface of the opposite screw rod 6 is provided with two symmetrically distributed spiral protrusions. The two symmetrically distributed spiral protrusions are arranged, so that the opposite screw rod 6 rotates synchronously during winding, so as to utilize the rotation of the spiral protrusions to cause the unwound geotextile to be flat and unfolded, effectively avoiding the situation that the geotextile is wrinkled and stacked during winding, and providing auxiliary outward force for the folding of the geotextile by the folding structure 8, facilitating stable folding work and winding work.

[0036] It is worth noting that the folding structure 8 includes a horizontal frame 801 and a folding pipe 802; at least one horizontal frame 801 is arranged on the mounting frame of the connecting frame 2 by bolts; and the folding pipe 802 is arranged at the end of the horizontal frame 801 in an inclined structure. The bolts can be conveniently used by workers to freely install and dismount the horizontal frame 801 and the folding pipe 802, so as to adapt to the laying work and the folding work during winding.

[0037] The folding pipe 802 is composed of a folding part 8021 and an expanding part 8022. The folding part 8021 is internally provided with a “C”-shaped cavity, and a limiting plate 8023 is arranged in the folding part 8021. The limiting plate 8023 extends into the expanding part 8022, and the expanding part 8022 is large at one end and small at the other end. The “C”-shaped cavity is provided, and the geotextile is partially folded in the winding process under the preliminary assistance of the artificial and the auxiliary outward force provided to the screw rod 6. The conventional geotextile is white or light-colored, and is laid on another group of geotextile, so that the overlapping part is more than 10 cm. The color of the geotextile is different from the color of the road. On a wide road, the folded geotextile can be directly laid along the edge of another geotextile. The color difference reduces the overlapping part, and the insufficient overlapping part caused by the visual difference of the driving carrier 1 and the insufficient operation experience is reduced, so that the operator can directly visually assist in improving the operation precision.

[0038] Working principle: first, the geotextile is partially folded and wound by manual assistance. One side of the geotextile is partially folded, and the folded side of the geotextile is inserted into the folding pipe 802, so that the folded part of the geotextile is matched with the “C”-shaped cavity. Then, the lower end of the geotextile is connected to the winding shaft 4. The servo motor 301 is driven to rotate the driving chain 305, so that the winding shaft 4 rotates to wind the geotextile. The winding is a basic folding and winding operation. Then, the folding structure 8 is disassembled. The driving carrier 1 is driven to move, and the servo motor 301 is reversely driven to rotate the driving chain 305, so that the winding shaft 4 rotates to unwind and lay the geotextile on the ground. If the road is wide, two or more geotextiles need to be laid side by side. The geotextile wound by the basic folding and winding is used as a guide, and the geotextile is laid on the guide. The servo motor 301 is reversely driven to rotate the driving chain 305, so that the winding shaft 4 rotates to unwind and lay the geotextile on the ground. Figure 6As shown, the edge of the first section of geotextile is aligned with the edge of the laid geotextile, and the color difference between the geotextile and the ground is used. The vehicle 1 is driven close to or away from the position of the first section of geotextile by prompting and precise control by personnel, so that the second section of geotextile overlaps with the first section of geotextile by at least 10CM, which is convenient for suturing and knotting the connection strength between the geotextiles. Then, if the geotextile is to be rolled up, one side of the geotextile is repeatedly partially folded, and the folded side of the geotextile is passed through the folding pipe 802, so that the folded part of the geotextile is adapted to the "C"-shaped cavity. Then, the lower end of the geotextile is connected to the winding shaft 4, and the vehicle 1 is driven to reverse along the laying method. Then, the drive chain 305 is rotated by the forward drive of the servo motor 301, causing The reel 4 is rotated to reel the geotextile, and at the same time, the auxiliary gear 501 and the driven chain 502 are driven to rotate, and the meshing block 702 is hinged to the inner sleeve 701, and under the elastic action of the spring 703, the meshing block 702 is engaged with the meshing groove 7041, so that the outer meshing gear disc 704 rotates synchronously with the inner sleeve 701 during the reeling operation, and the rotation of the spiral protrusion is used to cause the reeled geotextile to be spread out, effectively avoiding the situation of wrinkles and stacking during the reeling process, and at the same time providing auxiliary outward force for the operation of folding the geotextile of the folding structure 8, and through the setting of the "C"-shaped cavity, the edge of one side of the geotextile can be partially folded in half during the reeling process to complete the reeling work.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
