Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road paving, in particular to a width-adjustable mechanized emergency road paving mechanism. BACKGROUND

[0002] In some special cases, such as oil and gas field construction, road washed away by flood, road destroyed by war or poor road bearing capacity in the wild, it is necessary to lay some temporary and emergency construction roads or construction sites in advance to improve the road conditions and facilitate the passage of vehicles and personnel.

[0003] In order to facilitate the rapid paving of roads in the above-mentioned situations, various road paving vehicles are usually used at present to lay temporary roads on the ground. For example, a temporary road paving device disclosed in Chinese Patent No. CN217104620U includes a roller frame, a road roller, and a winding and unwinding device. The winding and unwinding device is drivingly connected with the road roller to drive the road roller to rotate relative to the roller frame to expand and lay or wind up the temporary road formed by the road roller. The above-mentioned temporary road paving device can not only realize the function of lifting and hoisting, but also can realize efficient laying or winding of temporary roads to ensure the smooth passage of construction vehicles. In addition, it does not damage the original construction road, which is beneficial to environmental protection.

[0004] However, in the above-mentioned temporary road paving device, the temporary road formed by laying the road roll on the ground is a bamboo strip type road, a roller blind type road or a block bamboo mat type road. The width of the road roll is fixed, which leads to the fixed width of the temporary road formed by laying. The width of the road roll cannot be adjusted according to the actual use requirements, which increases the road paving cost and reduces the construction efficiency. Specifically, when the width of the road to be paved is wider than the width of the road roll, the road roll needs to be laid more than twice or replaced with a wider road roll. When the width of the road to be paved is narrower than the width of the road roll, a lower width road roll needs to be replaced.

[0005] Therefore, it is necessary to improve the existing temporary road paving device. SUMMARY

DETAILED DESCRIPTION

[0036] In order to better understand the purpose, function and specific design scheme of the application, the width-adjustable mechanized emergency road paving mechanism of the application will be further described in detail below in combination with the drawings.

[0037] As Figures 1-15 shown, the width-adjustable mechanized emergency road paving mechanism of the application comprises:

[0038] The road paving vehicle 100 is provided with the winding frame 200.

[0039] The rotating assembly 300 and the winding drum 400 are arranged in a direction parallel to the width of the paving vehicle 100. The rotating assembly 300 drives the winding drum 400 to rotate around its own axis on the winding frame 200.

[0040] The road surface roll is wound on a winding drum 400 whose axial direction is parallel to its own width direction. The road surface roll includes road surface units 500 that are rotatably connected along its own winding path direction and whose rotation axis is parallel to the axial direction of the winding drum 400. The road surface unit 500 has a length direction parallel to the axial direction of the winding drum 400 and can extend and retract along its own length direction.

[0041] The adjustment component is used to drive the road surface unit 500 to telescopically move in order to adjust the width of the road surface roll.

[0042] In the width-adjustable mechanized emergency road paving mechanism of the present invention, the paving vehicle 100 is preferably a loader, i.e. a bulldozer, which can be widely used in construction projects such as highways, railways, buildings, ports, and mines. A winding frame 200 is provided at the front end of the paving vehicle 100, i.e. the end closest to its own cab. An adjusting cylinder 110 and a rotating arm 120 are provided between the paving vehicle 100 and the winding frame 200. By adjusting the extension and retraction of the piston rod of the adjusting cylinder 110, the winding frame 200 is moved, thereby adjusting the position of the winding frame 200 and the winding drum 400 on the winding frame 200.

[0043] The winding frame 200 includes a strip plate 210 extending parallel to the width direction of the paving vehicle 100 and winding arms 220 fixed at both ends of the strip plate 210 away from the paving vehicle 100. The winding drum 400 is rotatably disposed between the two winding arms 220. The strip plate 210 is hinged to the piston rod and rotating arm 120 of the adjusting cylinder 110.

[0044] like Figures 11-13 As shown, a rotating assembly 300 is mounted on one of the winding arms 220. The rotating assembly 300 includes a motor 310, a drive wheel 320, a synchronous belt 330, and a driven wheel 340. The motor 310 is fixed to the winding arm 220, and its output end is coaxially connected to the drive wheel 320. The drive wheel 320 is connected to the driven wheel 340 via the synchronous belt 330. Bearings 350 are provided on the outer sides of both winding arms 220, and the outer rings of the bearings 350 are fixed to the winding arms 220. A winding shaft 900 is provided between the two winding arms 220. One end of the winding shaft 900 is fixedly connected to the driven wheel 340. The two ends of the winding shaft 900 are cylindrical, and the cross-section of the middle part is cross-shaped. The two ends of the winding shaft 900 are fixedly connected to the inner rings of the two bearings 350, respectively. A winding cylinder 400 is sealed on the winding shaft 900.

[0045] When the motor 310 is started, the driving wheel 320 is driven to rotate, and the driving wheel 320 acts on the driven wheel 340 through the synchronous belt 330. Since the driven wheel 340 is coaxially fixedly connected with one end of the winding shaft 900, the winding shaft 900 rotates around the axis under the support of the two bearings 350, thereby driving the winding drum 400 to rotate. According to the rotation direction of the winding drum 400, the road surface roll is wound or unwound.

[0046] When the winding drum 400 rotates to wind the road surface roll, the road surface roll is wound on the winding drum 400, forming a structure as shown in Figure 5 and Figure 6 so as to facilitate the arrangement and collection of the road surface roll. During the winding and collecting process, the road paving vehicle 100 keeps retreating;

[0047] When the winding drum 400 reversely rotates to unwind the road surface roll, the part of the road surface roll away from the winding drum 400 is laid on the ground, forming a structure as shown in Figure 7 Meanwhile, the road paving vehicle 100 keeps advancing, and the wheels press the part of the road surface roll on the ground, so that the road surface roll laid on the ground forms a flat temporary road surface. The temporary road surface can improve the bearing capacity of the ground and facilitate the passage of vehicles and personnel through the temporary road surface.

[0048] The winding frame 200 is provided with two limiting rollers 230, which are axially parallel to the axial direction of the winding drum 400. The two limiting rollers 230 are respectively adjacent to the two sides of the winding path of the road surface roll. The gap between the two limiting rollers 230 is greater than the thickness of a single road surface unit 500. After the winding drum 400 rotates, the road surface unit 500 can pass through the gap between the two limiting rollers 230, and the two limiting rollers 230 can guide the movement path of the road surface roll, so that the road surface roll can be wound and unwound in an orderly manner.

[0049] The road surface roll in the present application is formed by a plurality of closely arranged road surface units 500 connected in sequence. The road surface unit 500 is long strip-shaped, and the length direction is parallel to the axial direction of the winding drum 400. Different from the prior art, the road surface unit 500 in the present application can perform stretching and contracting movement along the length direction, and is provided with an adjusting assembly. The adjusting assembly controls the stretching and contracting movement of the road surface unit 500 along the length direction, and changes the length of the plurality of road surface units 500, thereby changing the width size of the road surface roll. Therefore, during use, the width size of the temporary road surface can be controlled according to the need, the adjusting assembly drives the road surface unit 500 to perform stretching and contracting movement, so that the length size of the road surface unit 500 is consistent with the width of the temporary road surface. In this way, the road paving efficiency is improved and the paving cost is reduced without the need for multiple road paving. Therefore, by adjusting the width size of the road surface roll, the paving cost and time are saved, and the construction efficiency is improved.

[0050] In order to conveniently adjust the length size of the pavement unit 500, in the present application, the pavement unit 500 comprises pavement panels 600 which are sequentially and slidably connected along the width direction of the pavement roll, and the length direction of the pavement panel 600 is consistent with the sliding direction. After the above structure is adopted, the pavement unit 500 mainly comprises a plurality of pavement panels 600 which are sequentially connected, and the relative sliding between the pavement panels 600 can occur. Through the relative sliding between the adjacent pavement panels 600 and the sliding direction being parallel to the length direction of the pavement panel 600, the length of the pavement unit 500 can be changed and adjusted, and thus the use requirement that the width size of the pavement roll is adjustable can be met.

[0051] In order to conveniently realize the relative sliding between the adjacent two pavement panels 600, in the pavement unit 500, one of the adjacent two pavement panels 600 is a solid panel 610, and the other is a hollow panel 620. The hollow panel 620 has a strip-shaped cavity which faces the solid panel 610 and is matched with the solid panel 610.

[0052] Further specifically, as shown in Figures 8-10 In the present application, each pavement unit 500 comprises two solid panels 610 and three hollow panels 620 (in the actual application process, the number of the solid panels 610 and the hollow panels 620 can be adjusted according to the length size, and is not limited to the description in the present application). The two solid panels 610 and the three hollow panels 620 are distributed at intervals. Among the three hollow panels 620, the strip-shaped cavity openings of the hollow panels 620 located at the two ends face the solid panel 610. The strip-shaped cavity opening of the remaining hollow panel 620 has two openings which extend to the positions of the two ends of the hollow panel 620. In this way, the relative sliding between the two solid panels 610 and the three hollow panels 620 is facilitated, and thus the length size of the pavement unit 500 and the width size of the pavement roll can be adjusted.

[0053] Furthermore, the strip-shaped opening 621 and the protrusion 611 which are slidably and limitingly matched are arranged between the solid panel 610 and the hollow panel 620. The protrusion 611 slides on the inner side of the strip-shaped opening 621, and the strip-shaped opening 621 extends along the width direction of the pavement roll.

[0054] Specifically, the road surface panel 600 (including the solid panel 610 and the hollow panel 620) has two opposite planes in the thickness direction of the road surface panel 600, one of which is a load-bearing surface that is in contact with pedestrians and vehicles for bearing the pedestrians and vehicles when the road surface roll is laid on the ground, and the other is a laying surface that is in contact with the ground when the road surface roll is laid on the ground. The laying surface of the solid panel 610 has protrusions 611 at both ends, and the laying surface of the hollow panel 620 is provided with a strip-shaped opening 621 that is spaced apart from the end of the hollow panel 620. The protrusions 611 can slide along the strip-shaped opening 621, further ensuring the sliding fit of the solid panel 610 and the hollow panel 620. Since the strip-shaped opening 621 is spaced apart from the end of the hollow panel 620, the protrusions 611 cannot be separated from the strip-shaped opening 621, thus avoiding the separation of the solid panel 610 and the hollow panel 620.

[0055] Further improvement is that between the corresponding adjacent road surface panels 600 in the adjacent two road surface units 500, a rotating connection assembly 630 is arranged, and the road surface panels 600 are rotatably connected through the rotating connection assembly 630 and synchronously move in the width direction of the road surface roll.

[0056] Specifically, between the adjacent two road surface units 500, there are five rotating connection assemblies 630, which are respectively connected with the five road surface panels 600 of the road surface unit 500 one by one, so as to realize the rotating connection of the adjacent two road surface units 500, and when one of the road surface panels 600 in the road surface unit 500 moves in the width direction of the road surface roll, the corresponding road surface panel 600 in the adjacent road surface unit 500 synchronously moves to adjust the width size of the road surface roll.

[0057] Moreover, the adjacent two road surface units 500 are detachably connected through the rotating connection assembly 630, which facilitates the adjustment and control of the length size of the road surface roll wound on the winding drum 400. After the road surface is laid, the road surface unit 500 laid on the ground is detached from the road surface unit 500 wound on the winding drum 400. After the temporary road surface is used up, the road surface unit 500 laid on the ground is connected with the road surface unit 500 wound on the winding drum 400, which facilitates the winding and collection of all the road surface units 500 on the winding drum 400.

[0058] Specifically, as shown in FIG. 6, the rotating connection assembly 630 includes a rotating shaft 631 and a rotating plate 632. The rotating shaft 631 is rotatably connected with the rotating plate 632, and the rotating plate 632 is rotatably connected with the road surface panel 600. Figures 8-10As shown, one side of the solid plate 610 is integrally connected with a protrusion 615, the protrusion 615 is provided with a circular through hole extending along the length direction of the solid plate 610, the other side of the solid plate 610 is integrally connected with two protruding tabs 612 distributed side by side along the length direction of the solid plate 610, the two protruding tabs 612 are provided with a threaded rod 613, the threaded rod 613 has a cap portion at the first end, the middle portion is adapted to the circular through hole, the tail end away from the cap portion has an outer diameter smaller than that of the middle portion, and the tail end is threadedly connected with a nut 614. In this way, the protrusion 615, the threaded rod 613, the nut 614 and the two protruding tabs 612 combine to form a rotating connection assembly 630 between the solid plates 610.

[0059] The two sides of the hollow plate 620 are provided with notches 622, one side of the notches 622 is fixed with a fixed rod 623 extending along the length direction of the hollow plate 620, and the other side of the notches 622 is fixedly connected with a clamping piece 624 through a connecting rod, the clamping piece 624 is a clamping groove facing away from the fixed rod 623, the clamping groove is adapted to the fixed rod 623 for clamping and fitting with the fixed rod 623 on the corresponding hollow plate 620 of the adjacent pavement unit 500, and the inner wall of the clamping groove is an arc shape. In this way, the fixed rod 623 and the clamping piece 624 combine to form a rotating connection assembly 630 between the hollow plates 620.

[0060] When connecting two adjacent pavement units 500, the pavement plate 600 and the solid plate 610 of one pavement unit 500 are aligned with the pavement plate 600 and the solid plate 610 of the other pavement unit 500, and then the two pavement units 500 are brought close to each other, the clamping piece 624 is clamped with the fixed rod 623, the clamping piece 624 is attached to the two sides of the notches 622, and then the protrusion 615 is inserted between the two protruding tabs 612 and attached to the two protruding tabs 612, the threaded rod 613 is inserted between the protrusion 615 and the two protruding tabs 612, and the nut 614 is screwed at the end of the threaded rod 613, thereby connecting the two adjacent pavement units 500, and the two pavement units 500 are detachably connected.

[0061] The nut 614 is unscrewed, and then the threaded rod 613 is removed, the two hollow plates 620 in the two pavement units 500 are separated from each other, so that the clamping piece 624 is separated from the fixed rod 623, and the two pavement units 500 can be separated. In this way, the two adjacent pavement units 500 are detachably connected.

[0062] Further improvement is that the winding drum 400 is a hollow winding drum 400, a first strip-shaped through hole 411 extending along the self axial direction is arranged on the circumferential outer edge of the winding drum 400, the adjusting assembly is arranged in the winding drum 400, the output end penetrates the first strip-shaped through hole 411 and is connected with the road surface roll; the adjusting assembly comprises four first translation units 700 along the winding drum, the road surface unit 500 in the road surface roll which is adjacent to the winding drum 400 and is located at the end plate, the four road surface plates 600 located at the two side positions are connected with the four first translation units 700 one by one, that is, in the four first translation units 700, the output end of two first translation units 700 is connected with the two hollow plates 620 at the end, and the output end of the other two first translation units 700 is connected with the two solid plates 610.

[0063] Specifically, as shown in Figure 14 and Figure 15 The winding drum 400 comprises a drum body 410 and a drum cover 420 fixed to one end of the drum body 410, and the inner side of the drum body 410 is fixed with a drum core 440, and the drum core 440 and the drum cover 420 are sealingly sleeved on the winding shaft 900 to realize synchronous rotation of the winding drum 400 and the winding shaft 900.

[0064] The first strip-shaped through hole 411 extends along the axial direction of the winding drum 400 and is arranged on the circumferential side wall of the drum body 410, the first translation unit 700 is a first translation oil cylinder, the cylinder barrel of which is fixed between the circumferential outer side wall of the drum core 440 and the circumferential inner side wall of the drum body 410, the piston rod is fixedly connected with a connecting shaft 701 which extends along the radial direction of the winding drum 400 and penetrates the first strip-shaped through hole 411, and the end of the connecting shaft 701 away from the first translation oil cylinder is provided with a movable rotating seat 702, the movable rotating seat 402 is connected with the end of the road surface roll, that is, the road surface plate 600 in the road surface unit wound on the drum body 410, and the outer side wall of the drum body 410 is provided with a positioning rotating seat 450, the positioning rotating seat 450 is connected with the road surface plate 600 at the middle position of the end of the road surface roll, so that the road surface unit at the end of the road surface roll can be rotationally connected with the drum body 410 and the rotation axis is parallel to the axis of the drum body 410.

[0065] Among the four movable rotating seats 702 connected with the four first translation units 700, two are connected with the hollow plates 620 at the two end positions of the road surface unit, and the other two are connected with the two solid plates 410, and the positioning rotating seat 450 is connected with the hollow plate 420 at the middle position.

[0066] With the above structure, the winding drum 400 adopts a hollow structure, which is beneficial to reduce the weight, thereby reducing the energy consumed by the rotating assembly 300 to drive the rotation, achieving energy saving, and the adjusting assembly is arranged inside the winding drum 400, and the four road surface panels 600 are driven to move axially by the four first translation units 700 respectively, and the hollow plate 620 located in the middle is fixed in the axial position, which not only makes the overall structure of the device more compact, but also meets the needs of adjusting the width size of the road surface roll, and in addition, when the four first translation units 700 drive the four road surface panels 600 to move in the same direction, the axial position of the road surface roll on the winding drum 400 can also be adjusted, thereby adjusting the paving position of the road surface.

[0067] Further improvement is that the winding drum 400 is further provided with a limiting disc 430 fitted on both sides of the road surface roll, and the limiting disc 430 is connected with a second translation unit 800 for driving the limiting disc 430 to move axially along the winding drum 400; and the second translation unit 800 is arranged in the winding drum 400.

[0068] Specifically, as shown in Figures 13-15 The second strip-shaped through hole 412 extends axially along the winding drum 400 and is arranged on the drum body 410, the limiting disc 430 is a limiting ring, a sealing sleeve is arranged outside the drum body 410, and one end face thereof is fitted with one side of the road surface roll, so as to ensure the winding quality of the road surface roll on the winding drum 400; and the inner side of the limiting disc 430 is integrally connected with a convex shaft 431 extending radially along the winding drum 400, the convex shaft 431 penetrates through the second strip-shaped through hole 412 and extends into the inner cavity of the winding drum 400, and the second translation unit 800 is a second translation oil cylinder, the cylinder barrel of which is fixed on the drum core 440, and the piston rod is connected with a sleeve ring 801, which is sealingly arranged on the end of the convex shaft 431.
