Description

Technical Field

[0002] Pavement operation is an operation structure used to form a passage on a soil road surface with low bearing capacity, so as to improve the vehicle's ability to pass on the road surface. The existing pavement operation device adopts an integral lifting drum, and the pavement is rolled up on the drum to retract and release the road panel, and the drum is lifted to different heights to adapt to the operation of pavement rolls of different lengths. The distance from the center of the drum to the bottom of the operation device determines the length of the road surface that the operation device can accommodate.

[0024] See also Figures 1 to 10 According to the embodiment of the present application, the detachable road working device includes: a chassis vehicle system 100, a rotating frame structure 200, a support frame structure 300 and a drum structure 400.

[0025] See also Figures 1 to 3 The rotating frame structure 200 includes a rotating frame 210 and a through-cabin tube 220. Two through-cabin tubes 220 are respectively arranged on both sides of the two ends of the rotating frame 210. The supporting frame structure 300 is set to two. The two supporting frame structures 300 are respectively arranged on the upper sides of the two ends of the rotating frame 210. The supporting frame structure 300 includes a supporting member 310, a pin-connecting seat 320 and an elevated frame 330. The pin-connecting seat 320 is fixedly connected to both sides of the lower end of the supporting member 310. The pin-connecting seat 320 is fixed to the two through-cabin tubes 220 on the rotating frame 210 by double pins. Both sides of the elevated frame 330 can be connected to the inner side of the pin-connecting seat 320. The two ends of the reel structure 400 are respectively rotatably connected to the supporting members 310 of the two supporting frame structures 300. When the length of the pavement roll needs to be increased, the double pins on the pin-joint seat 320 are pulled out, the support frame structure 300 and the reel structure 400 are hoisted, the heightening frame 330 is pre-connected to the inner side of the pin-joint seat 320, the support frame structure 300 and the reel structure 400 are dropped, the pin-joint seat 320 is re-dropped on the rotating frame 210, the position of the pin-joint seat 320 is adjusted, the pin-joint seat 320 and the through-cabin tube 220 are aligned, and the double pins are re-inserted into the pin-joint seat 320 and the through-cabin tube 220 for double pin connection, the support member 310 is increased through the heightening frame 330, and the height of the center of the reel structure 400 on the support member 310 from the rotating frame 210 is also increased, thereby achieving the purpose of increasing the space for accommodating the pavement and increasing the storage length of the pavement roll. When it is necessary to consider meeting the requirements of road transportation, the heightening frame 330 is operated in the reverse order of installation, the heightening frame 330 is taken out, and the height of the reel structure 400 is lowered to meet the requirements of road transportation. Secondly, the pin connector 320 adopts a double-pin connection method, so that the lifting support frame structure 300 and the drum structure 400 can be disassembled and assembled as a whole, so as to facilitate the separate packaging and transportation of the support frame structure 300 and the drum structure 400, and meet the single-machine multi-road operation mode. In addition, after the support frame structure 300 and the drum structure 400 are dismantled, it is convenient to install other models or types of upper mounting mechanisms.

[0026] See also Figures 1 to 3 The slewing frame 210 includes a longitudinal beam 211, a transverse beam 212 and a connecting frame seat 213. The longitudinal beam 211 and the transverse beam 212 are both provided in two pieces. The two ends of the two longitudinal beams 211 are fixedly connected by the transverse beam 212 to form a frame. The connecting frame seat 213 is provided in the middle of the frame. The connecting frame seat 213 is fixedly connected to the chassis vehicle system 100. Two through-cabin pipes 220 are fixedly penetrated in the transverse direction of both ends of the longitudinal beam 211. The frame surrounded by the longitudinal beam 211 and the transverse beam 212 is used to support the support frame structure 300 and the reel structure 400. The frame is connected to the chassis vehicle system 100 through the connecting frame seat 213, and the connecting frame seat 213 is used to bear the frame and the weight thereon.

[0027] See also Figures 1 to 3The support member 310 includes a support frame 311, a lifting cylinder 312, a lifting beam 313, a bearing seat 314 and a drum motor 315, one end of the lifting beam 313 is hinged to the top of one end of the support frame 311, the top of the other end of the support frame 311 can block the other end of the lifting beam 313, and the end of the lifting beam 313 away from the hinge of the lifting beam 313 extends out of the support frame 311, the bearing seat 314 is connected to the lifting beam 313, both ends of the drum structure 400 are respectively connected to the bearing seats 314 on the two lifting beams 313, the drum motor 315 is arranged on the lifting beam 313, the drum motor 315 is connected to the drum structure 400, one end of the lifting cylinder 312 is hinged to the end of the bottom of the support frame 311 away from the hinge of the lifting beam 313, and the other end of the lifting cylinder 312 is hinged to the end of the lifting beam 313 extending out of the support frame 311. When the reel structure 400 is performing the winding operation, the lifting cylinder 312 is started, and the lifting cylinder 312 pushes one end of the lifting beam 313 to rotate upward around the hinge. As the lifting beam 313 swings upward, the lifting beam 313 drives the bearing seat 314 to rise, and the bearing seats 314 on the two lifting beams 313 drive the reel structure 400 to rise synchronously, thereby increasing the winding space of the reel structure 400 with the road surface roll, which is convenient for storing the road surface roll. The reel motor 315 drives the reel structure 400 to rotate to retract and release the road surface, and the road surface roll is affected by the initial winding position of the reel structure 400 and is elliptical. When the major axis of the ellipse is aligned with the horizontal direction of the lifting beam 313, the lifting cylinder 312 is dropped, so that the lifting beam 313 drives the reel structure 400 to fall after storing the road surface roll. At this time, the short axis is in a vertical position and the long axis is in a horizontal position, thereby reducing the height occupied by the road surface roll, which is convenient for adapting to road driving requirements.

[0028] See also Figures 1 to 4 The chassis system 100 includes a chassis 110, a slewing mechanism 120 and a tail guide wheel 130. The slewing mechanism 120 is arranged on the chassis 110, the slewing frame 210 is arranged on the slewing mechanism 120, the tail guide wheel 130 is arranged at the tail of the chassis 110, and mounting beams 230 are arranged on both sides of the slewing frame 210.

[0029] See also Figures 1 to 5The slewing mechanism 120 includes a slewing mounting plate 121, a slewing bearing 122, a slewing motor 123, and a driving gear 124. The slewing mounting plate 121 is fixedly connected to the chassis 110, the outer ring of the slewing bearing 122 is fixed to the upper side of the slewing mounting plate 121, the slewing motor 123 is fixed to the upper side of the slewing mounting plate 121, the output end of the slewing motor 123 passes through the slewing mounting plate 121 and extends to the upper side of the slewing mounting plate 121, the driving gear 124 is fixedly connected to the output end of the slewing motor 123, the driving gear 124 is meshed with the inner ring of the slewing bearing 122, and the slewing frame 210 is fixed to the upper side of the inner ring of the slewing bearing 122. When the reel structure 400 is retracted and released, the rotary motor 123 is started, and the rotary motor 123 drives the inner ring of the slewing bearing 122 to rotate around the outer ring. The outer ring of the slewing bearing 122 is fixed on the slewing mounting plate 121, and the inner ring of the slewing bearing 122 drives the slewing frame 210 to rotate. The support frame structure 300 and the reel structure 400 rotate with the slewing frame 210, and the reel structure 400 is adjusted from the longitudinal direction of the vehicle body to the transverse direction of the vehicle body, so as to facilitate the retracting and releasing of the reel structure 400 when the chassis 110 is traveling. On the contrary, after the retracting and releasing operation is completed, the rotary motor 123 reverses and drives the reel structure 400 back to the longitudinal direction of the vehicle body, so as to facilitate the chassis 110 to travel on the road and meet the requirements of highway driving.

[0030] See also Figures 1 to 6The pin-jointed seat 320 includes a cross-beam seat body 321, an elastic card plate portion 323 and a locking pin 324. The cross-beam seat body 321 is fixedly connected to both sides of the lower end of the support member 310. Two rows of pin-jointed holes 322 are horizontally opened on the cross-beam seat body 321, and each row is provided with two pin-jointed holes 322. An elastic card plate portion 323 is provided between the two pin-jointed holes 322 in each row. The two elastic card plate portions 323 are fixedly connected to the side walls of the cross-beam seat body 321. A locking pin 324 is inserted into the two pin holes 322 in each row, and the two ends of the elastic clamping plate part 323 can block the two locking pins 324. The cross beam seat body 321 is inserted into the longitudinal beam 211. The two sides of the heightening frame 330 can be connected to the inner side of the cross beam seat body 321. The cross beam seat body 321 can press the heightening frame 330 onto the longitudinal beam 211, and the two locking pins 324 are respectively inserted into the two through-cabin pipes 220 at the same end of the longitudinal beam 211. When the height-raising frame 330 is not installed, the cross-beam seat body 321 is stuck on the longitudinal beam 211, and the weight borne on the cross-beam seat body 321 is pressed on the longitudinal beam 211. The pin holes 322 on the cross-beam seat body 321 and the through-cabin tube 220 on the longitudinal beam 211 are aligned, and the locking pins 324 are passed through the pin holes 322 on the cross-beam seat body 321 and the through-cabin tube 220, and the cross-beam seat body 321 is locked on the longitudinal beam 211 by the two locking pins 324. Thereafter, the locking pins 324 are rotated so that the two ends of the elastic clamping plate portion 323 block the edges of the locking pins 324 to reduce the falling off of the locking pins 324. When installing the heightening frame 330, first take out the two locking pins 324, lift the support frame structure 300, separate the cross beam seat body 321 from the longitudinal beam 211, install the heightening frame 330 into the cross beam seat body 321, and use bolts to pre-connect the heightening frame 330 to the interior of the cross beam seat body 321. Note that the bolts should not be tightened at this time. Since the cross beam seat body 321 is provided with a bolt hole, the bolt hole diameter is larger than the outer diameter of the bolt rod, so that the heightening frame 330 has a movable margin in the up and down directions. Drop the support frame structure 300, the cross beam seat body 321 presses the heightening frame 330 on the longitudinal beam 211, and adjust the position of the cross beam seat body 321 so that the cross beam seat body 32 The pin holes 322 in the lower row are aligned with the cabin tube 220 on the longitudinal beam 211, and then the bolts connected to the heightening frame 330 are tightened, so that the heightening frame 330 maintains a state of connection between the two sides, and the cross beam seat body 321 can press the heightening frame 330 on the longitudinal beam 211, thereby reducing the movement of the heightening frame 330. In addition, the pressure on the heightening frame 330 acts on the longitudinal beam 211, thereby reducing the force on the bolts at the connection and reducing the failure of the connection. After the heightening frame 330 is connected, the cross beam seat body 321 is locked on the longitudinal beam 211 through the locking pin 324 and the pin holes 322 in the lower row of the cross beam seat body 321, thereby increasing the height of the reel structure 400.

[0031] See also Figures 1 to 7The cross beam seat body 321 includes a base plate 3211, a side plate 3212 and a reinforcement plate 3213. The side plates 3212 are fixedly connected to the two ends of the lower side of the base plate 3211. The reinforcement plate 3213 is fixedly connected to the lower side of the base plate 3211 and the outer side of the side plates 3212. Pin holes 322 are opened through the two side plates 3212. The side plates 3212 are attached to both sides of the longitudinal beam 211. The pin holes 322 correspond to the through-cabin pipe 220. The locking pin 324 passes through the pin holes 322 on one of the side plates 3212, the through-cabin pipe 220 and the pin holes 322 on the other side plate 3212 in sequence. The main body of the cross beam seat body 321 is composed of two side panels 3212 and a base panel 3211, and the strength of the connection between the side panels 3212 and the base panel 3211 is enhanced by a reinforcing plate 3213. The two side panels 3212 are inserted into both sides of the longitudinal beam 211, and the base panel 3211 is pressed on the upper side of the longitudinal beam 211 directly or through an elevated frame 330. The locking pin 324 then passes through the side panels 3212 on the outside of the longitudinal beam 211, the cabin pipe 220 and the other side panel 3212 in sequence to lock the cross beam seat body 3211 on the longitudinal beam 211.

[0032] See also Figures 1 to 8 The elastic clamping plate portion 323 includes a connecting plate 3231, a fastener 3232 and a spring piece 3233. The connecting plate 3231 is fixed to the outer wall of the side plate 3212 on the outer side of the longitudinal beam 211 through the fastener 3232. The spring piece 3233 is arranged at both ends of the connecting plate 3231. The spring piece 3233 is concave to form a buckle 3234. The buckle 3234 can be clamped into the locking pin 324 through the elastic deformation of the spring piece 3233. After the locking pin 324 locks the cross beam seat body 321, the locking pin 324 is rotated so that the edge of the locking pin 324 is stuck on the buckle 3234, thereby reducing the rotation of the locking pin 324 and keeping the spring piece 3233 blocked by the spring piece 3233, thereby reducing the occurrence of the situation where the locking pin 324 is separated from the cross beam seat body 321 due to the rotation. The locking pin 324 can be quickly connected by rotation, and the locking pin 324 can be separated from the spring piece 3233 by elastic deformation of the spring piece 3233, and then rotating the locking pin 324, so that the disassembly is simple, fast and convenient.

[0033] See also Figures 1 to 9The locking pin 324 includes a pin body 3241, a limiting plate 3242 and a hand-held rod 3244. The limiting plate 3242 is fixedly sleeved on one end of the pin body 3241. The limiting plate 3242 is a waist-shaped plate. The outer ends of the waist-shaped plate in the long axis direction are provided with slots 3243. The spring piece 3233 can block the long axis direction of the waist-shaped plate. The buckle 3234 can be inserted into the slot 3243. The short axis direction of the waist-shaped plate can be separated from the spring piece 3233. The hand-held rod 3233 is fixedly connected to the end of the pin body 3241 close to one end of the limiting plate 3242. The pin body 3241 passes through the side plate 3212, the through-cabin pipe 220 and the other side plate 3212 on the outside of the longitudinal beam 211 in sequence to be locked. The side plate 3212 on the outside of the longitudinal beam 211 blocks the limit plate 3242. The pin body 3241 and the limit plate 3242 are driven to rotate by the hand-held rod 3244. The short axis of the limit plate 3242 approaches the spring piece 3233, so that the limit plate 3242 passes over the spring piece 3233. The limit plate 3242 rotates, and the spring piece 3233 blocks the edge of the long axis of the limit plate 3242. The buckle 3234 is snapped into the slot 3243 to limit the rotation of the limit plate 3242, thereby limiting the rotation of the pin body 3241, reducing the occurrence of the pin body 3241 jumping out of the pin connection hole 322 on the side plate 3212 and the through-cabin pipe 220, thereby reducing the occurrence of pin connection failure of the pin body 3241.

[0034] See also Figures 1 to 10 The reel structure 400 includes a cylinder 410, a winding frame 420, a limiting frame 430 and a ring gear 440. The winding frame 420 is fixedly sleeved on the cylinder 410, and the limiting frame 430 is fixedly sleeved on both ends of the cylinder 410. The two ends of the cylinder 410 are rotatably connected to the bearing seats 314 on the two lifting beams 313, respectively. The ring gear 440 is fixedly connected to the outside of the limiting frame 430, and the reel motor 315 is meshed with the ring gear 440 through gears. When the road panel is rolled up, the reel motor 315 is started, and the reel motor 315 drives the ring gear 440 and the limiting frame 430 to rotate through the gear meshing principle, and the cylinder 410 rotates in the two bearing seats 314, and the road panel is rolled up on the reel frame 420, and the reel frame 420 is elliptical, which is convenient for guiding the road panel to be elliptical and wound on the reel structure 400 to form an elliptical road roll.

[0035] Specifically, the working principle of the detachable road working device is as follows: when the heightening frame 330 is not installed, the two side plates 3212 of the cross beam seat body 321 are inserted into the two sides of the longitudinal beam 211, and the weight carried on the cross beam seat body 321 is pressed on the longitudinal beam 211. The pin holes 322 on the two side plates 3212 are aligned with the through-cabin tube 220 on the longitudinal beam 211, and the pin bodies 3241 pass through the pin holes 322 on the side plates 3212 on the outer side of the longitudinal beam 211, the through-cabin tube 220 and the pin holes 322 on the other side plates 3212 in sequence to lock them. The side plates 3212 on the outer side of the longitudinal beam 211 block the limit plates 3242, and the cross beam seat body 321 is locked on the longitudinal beam 211 through the pin bodies 3241 of the two locking pins 324. 1, and then, the pin body 3241 and the limit plate 3242 are driven to rotate by the hand-held rod 3244, and the short axis of the limit plate 3242 is close to the spring sheet 3233, so that the limit plate 3242 passes over the spring sheet 3233, and the limit plate 3242 rotates, and the spring sheet 3233 blocks the edge of the long axis of the limit plate 3242, and the buckle 3234 is snapped into the slot 3243, so as to limit the rotation of the limit plate 3242, and then limit the rotation of the pin body 3241, so as to reduce the occurrence of the pin body 3241 jumping out of the pin connection hole 322 on the side plate 3212 and the cabin pipe 220, and then reduce the occurrence of the pin connection failure of the pin body 3241. At this time, the drum structure 400 is not raised to meet the requirements of road transportation.

[0036] When installing the heightening frame 330, the hand-held rod 3244 drives the pin body 3241 and the limit plate 3242 to rotate, so that the slot 3243 on the limit plate 3242 leaves the buckle 3234, and the limit plate 3242 is separated from the spring piece 3233 through the short axis direction of the limit plate 3242, and then the hand-held rod 3244 is used to pull out the pin body 3241, so that the double pin lock of the side plate 3212 on the cross beam seat body 321 is released, and the support frame structure 300 is hoisted, so that the base plate 3212 is lifted. 211 is separated from the longitudinal beam 211, and the heightening frame 330 is installed between the base plate 3211 and the longitudinal beam 211. The heightening frame 330 is pre-connected to the inner side of the side plate 3212 with bolts. Note that the bolts should not be tightened at this time. Since the side plate 3212 is provided with a bolt hole, the bolt hole diameter is larger than the outer diameter of the bolt rod, so that the heightening frame 330 has a movable margin in the up and down direction. The support frame structure 300 is dropped, and the base plate 3211 presses the heightening frame 330 on the longitudinal beam 21 1, adjust the position of the cross beam seat body 321, so that the pin holes 322 in the lower row of the two side plates 3212 and the cabin pipe 220 on the longitudinal beam 211 are aligned, and then tighten the bolts connected to the heightened frame 330, so that the heightened frame 330 maintains a connection on both sides, and the base plate 3211 can press the heightened frame 330 on the longitudinal beam 211 to reduce the movement of the heightened frame 330. In addition, the pressure on the heightened frame 330 acts on the longitudinal beam 211, reducing the bolts at the connection. The stress is reduced to reduce the failure of the connection. After the raising frame 330 is connected, the cross beam seat body 321 is locked on the longitudinal beam 211 through the locking pin 324 and the pin connection holes 322 in the lower row of the cross beam seat body 321, thereby increasing the height of the drum structure 400. After being increased by the raising frame 330, the height of the drum structure 400 from the center of the support member 310 to the revolving frame 210 is also increased, thereby achieving the purpose of increasing the space for accommodating the road surface and increasing the storage length of the road surface roll.

[0037] The support frame structure 300 and the drum structure 400 are connected by a double pin by a pin connection seat 320. The support frame structure 300 and the drum structure 400 can be lifted and disassembled as a whole to facilitate the separate packaging and transportation of the support frame structure 300 and the drum structure 400, meeting the single-machine multi-road operation mode. In addition, after the support frame structure 300 and the drum structure 400 are dismantled, it is convenient to install other models or types of upper mounting mechanisms.

[0038] When the reel structure 400 is being retracted and released, the rotary motor 123 is started, and the rotary motor 123 drives the inner ring of the slewing bearing 122 to rotate around the outer ring. The outer ring of the slewing bearing 122 is mounted on the slewing mounting plate 121 and is fixed. The inner ring of the slewing bearing 122 drives the slewing frame 210 to rotate, and the support frame structure 300 and the reel structure 400 rotate along with the slewing frame 210. The reel structure 400 is adjusted from along the longitudinal direction of the vehicle body to along the transverse direction of the vehicle body, so as to facilitate the retraction and release of the reel structure 400 when the chassis vehicle 110 is traveling. After the reel structure 400 is adjusted to along the transverse direction of the vehicle body, the lifting cylinder 312 is started, and the lifting cylinder 312 pushes one end of the lifting beam 313 to rotate upward around the hinge. As the lifting beam 313 swings upward, the lifting beam 313 drives the bearing seat 314 to rise, and the bearing seats 314 on the two lifting beams 313 drive the reel structure 400 to rise synchronously, thereby improving the belt road surface. The winding space of the reel structure 400 is convenient for storing the pavement roll. The reel motor 315 drives the ring gear 440 and the limit frame 430 to rotate through the gear meshing principle. The cylinder 410 rotates in the two bearing seats 314. The pavement panel is wound on the winding frame 420, and the winding frame 420 is elliptical, which is convenient for guiding the pavement panel to be elliptical and wound on the reel structure 400 to form an elliptical pavement roll. When the major axis of the ellipse is aligned with the horizontal direction of the lifting beam 313, the lifting cylinder 312 is dropped, so that the lifting beam 313 drives the reel structure 400 after storing the pavement roll to fall. At this time, the short axis is in a vertical position and the long axis is in a horizontal position, which reduces the height occupied by the pavement roll and is convenient for adapting to the road driving height requirements. After the reeling and unwinding operation is completed, the rotary motor 123 reverses and drives the reel structure 400 back to the longitudinal direction of the vehicle body, which is convenient for the chassis vehicle 110 to meet the road driving width requirements when driving on the road.

[0039] It should be noted that both the rotary motor 123 and the drum motor 315 are hydraulic motors. The specific model and specifications of the hydraulic motors need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0040] The rotary motor 123 and the reel motor 315 are driven by the fluid supply of the chassis 110. The specific fluid supply and its principle are clear to those skilled in the art and will not be described in detail here.
