Description

Technical Field

[0001] This invention relates to the field of laying and winding vehicle technology, specifically an electric laying and winding vehicle. Background Technology

[0002] In an increasing number of areas in our lives, including airports, parking lots, and construction sites, the laying and rewinding of roll materials is required. Existing laying and rewinding devices are mainly single laying devices or single rewinding devices. There are currently no devices that can simultaneously lay and rewind. The single function of laying and rewinding limits the scope of application of laying and rewinding devices and also increases the construction cost of laying and rewinding.

[0003] Typically, when laying and rewinding camouflage materials in areas such as airports, parking lots, and construction sites, the construction area is large, requiring a significant amount of manpower and time, which greatly increases the difficulty of laying and rewinding the camouflage materials. Therefore, a vehicle capable of both laying and rewinding is needed. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of difficult roll material laying and winding, and to provide an electric laying and winding vehicle that can quickly lay and wind up roll materials.

[0005] To achieve the above objectives, the specific technical solution of the present invention is as follows:

[0006] An electric laying and winding vehicle includes a frame 1, front and rear axles and a steering structure 2, a tail plate 3, an electric laying and winding device 4, and a control box 5. The frame 1 includes a bottom plate 6, a front step 7, a square tube frame 8, a tail plate 9, and a tail plate frame 10. The bottom plate 6 and the front step 7 are both welded to the square tube frame 8. The tail plate 9 is welded to the tail plate frame 10. The front and rear axles and the steering structure 2 are welded to the bottom of the frame 1. A metal sleeve is welded to one end of the tail plate frame 10, and a metal sleeve is welded to the end of the frame 1 near the control box 5. The control box 5 is welded inside the square tube frame 8. The electric laying and winding device 4 is connected to the square tube on the bottom plate 6 via a shaft fixing seat. The tail plate 3 is movably connected to the bottom plate 6.

[0007] The bottom plate 6, the front pedal 7, and the rear pedal 9 are all made of steel plates.

[0008] The bottom plate 6 is equipped with a limiting square tube 6-1, a limiting structure 6-2, a mounting block 6-3, and a gap 6-4. The limiting square tube 6-1 consists of two sets of square tubes welded side by side on the bottom plate 6. When the electric laying and winding device 4 is installed or removed along the tail plate 3 and the bottom plate 6, the limiting square tube 6-1 prevents deviation during the rolling process. The limiting structure 6-2 consists of two vertical square tubes welded to the bottom plate 6 with a distance of 15mm between them. It prevents the electric laying and winding device 4 from deviating to the left or right when it rotates. The mounting block 6-3 is fixedly installed on the bottom plate 6, and the electric laying and winding device 4 is fixed to the bottom plate 6 through the mounting block 6-3.

[0009] The electric laying and winding device 4 includes a winding roller 19, a drive unit 20, and a drive shaft 21; the drive unit 20 includes a drive motor 30, a chain 31, and an adjustable torque limiter 32; the drive shaft 21 includes a drive rod 34, a driven rod 35, a shaft fixing seat 33, and friction rubber 36; the drive unit 20 is fitted into the drive shaft 21 through the adjustable torque limiter 32, and the drive unit 20 is limited by a key block to drive the drive shaft 21 to rotate; the drive motor 30 is connected to the adjustable torque limiter 32 via the chain 31. The torque limiter 32 is connected and is an adjustable torque limiter 32 used to prevent the motor from burning out due to overload. When the drive shaft 21 is stuck or the load on the take-up drum 19 is too large, causing the adjustable torque limiter 32 to exceed a certain torque, the adjustable torque limiter 32 will idle and will no longer provide driving force to the drive shaft 21 to prevent the drive motor from burning out. The friction rubber 36 is sleeved on the drive shaft 21 and contacts the take-up drum 19, thereby driving the take-up drum 19 to rotate. The chain 31 passes through the gap 6-4 to drive the laying and take-up device 4 to rotate.

[0010] The front and rear axles and steering structure 2 include a rear axle 11, a front axle 12, a steering structure 13, and a brake control line 14; the rear axle 11 is used to drive the vehicle, the steering structure 13 controls the steering of the front axle 12, and the brake control line 14 is connected to the rear axle 11 to brake the rear axle 11; the drive motor 30 is directly integrated on the rear axle 11 and is an integral structure with the rear axle 11, and is used to drive the vehicle.

[0011] The steering structure 13 includes a rearview mirror 26, a steering wheel 27, a steering rod 28, and a steering assist 29. The rearview mirror 26 and the steering wheel 27 are both fixed to the crossbar at the top of the steering rod 28. The lower end of the steering rod 28 is connected to the steering assist 29, which is a spring-hydraulic rod. When the steering wheel 27 is turned, the spring-hydraulic rod provides assistance, making steering easier.

[0012] The tail plate 3 includes rollers 15, rollers 16, pads 17, and a tail plate frame 18; the pads 17 are welded to the tail plate frame 18; the rollers 15 are installed on the side of the tail plate frame 18 away from the rollers 16 by screws, and one roller is installed at each of the two corners of the tail plate frame 18. When the tail plate falls, the rollers 15 contact the ground, supporting the tail plate and facilitating the rolling and handling of the roll material; the rollers 16 are fixed to the tail plate frame 18 on the side away from the rollers.

[0013] The number of rollers 16 is 2 to 4. The roll material is wound in an "S" shape on the rollers 16, which is used to guide the roll material when it is being wound up, and at the same time removes larger foreign objects from the surface of the roll material.

[0014] The control box 5 includes an operation panel 22, a mounting plate 23, a battery pack 24, and a control box cover plate 25. The control switch is mounted on the mounting plate 23. The operation panel 22 has pre-drilled holes, and the control switch protrudes from the operation panel 22 for easy operation. The battery pack 24 is placed inside the control box 5 and is used for the power supply of the entire vehicle. The control box 5 is encapsulated by eight control box cover plates 25. The control box 5 includes two cover plates on the front side, two cover plates on the rear side, one cover plate on the left side, one cover plate on the right side, and two cover plates on the bottom. The eight control box cover plates 25 are welded and mounted on the frame 1 inside the square tube frame 8.

[0015] The frame 1 extends downwards with four square tube ends 1-a, which are the connection points between the frame 1 and the front and rear axles and steering rods 2. The square tube ends 1-a are welded to 2-a on the front and rear axles and steering structure 2, with 2-a being the connection point between 1-a and the front and rear axles and steering structure 2. The front and rear axles and steering structure 2 are fixed to the frame 1, with 1-b being the connection point between the frame 1 and the tailplate 3. This enables the vehicle to move forward, backward, and turn. Two metal sleeves are welded to 1-b of the frame 1, and two corresponding metal sleeves are welded to 3-b of the tailplate 3, with 3-b being the connection point between 1-b and the tailplate 3. A rotating shaft is simultaneously fitted into 1-b of the frame 1 and 3-b of the tailplate 3, with 3-b being the connection point between 1-b and the tailplate 3. This enables the tailplate 3 to rotate at the rear of the frame 1. The tailplate retracts upwards during vehicle laying and winding. When new rolls need to be replaced during laying or during winding, the tailplate rotates upwards. When changing to a fully wound roll, the tail plate drops down to push the roll up and down; section 1-c of the frame 1 consists of two horizontal square tubes, and 1-c is the connection point between the frame 1 and the laying and winding device 4; section 4-c of the electric laying and winding device 4 is a shaft fixing seat, and 4-c is the connection point between the laying and winding device 4 and 1-c. The shaft fixing seat is placed on the horizontal square tubes and fixed with screws passing through the square tubes; section 1-d of the frame 1 has six vertical square tubes, and 1-d is the connection point between the frame 1 and the control box 5. The metal cover plate of section 5-d of the control box 5 is fixed to the square tubes by welding, and 5-d is the connection point between the control box 5 and 1-d. Various control switches are installed inside the control box 5; section 1-e of the frame 1 is used for the installation of the drive equipment. The drive motor mounting plate is fixed to the square tube of section 1-e of the frame 1 with screws, and 1-e is the connection point between the frame 1 and the drive equipment.

[0016] The transmission path of the vehicle laying and winding process is as follows: the drive motor 30 drives the adjustable torque limiter 32 to rotate through the chain 31, and the adjustable torque limiter 32 transmits the power to the winding drum 19 through the friction rubber 36 on the drive shaft 21 to realize the winding and laying of the laying vehicle.

[0017] When the drive motor 30 rotates clockwise, it drives the take-up roller 19 to complete the laying process. When the drive motor 30 rotates counterclockwise, it drives the take-up roller 19 to complete the winding process. If there is jamming during the transmission process, or if the load on the take-up roller 19 is too large during the laying and winding of the roll material, the adjustable torque limiter 32 will automatically disconnect the power transmission due to excessive torque. The adjustable torque limiter 32 will automatically idle, effectively preventing the drive motor 30 from burning out due to excessive torque.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] (1) The present invention realizes the laying and winding operations of the vehicle by controlling the forward and reverse rotation of the drive motor;

[0020] (2) Personnel operation is always consistent with the vehicle's forward direction, which facilitates observation during the operation process;

[0021] (3) The tail plate can rotate along the rotating shaft to retract or fall. During the laying and winding device disassembly or installation process, the winding drum can be manually pushed down or up along the tail plate. When the winding drum finishes winding, the weight of the winding drum increases, making it easier for personnel to replace the winding drum.

[0022] (4) A friction torque limiter is used between the vehicle rear axle drive motor and the take-up shaft drive motor. When there is a jam in the transmission process, or the load is too large during the laying and winding of the take-up roller, the adjustable torque limiter will automatically disconnect the power transmission due to excessive torque. The adjustable torque limiter will automatically idle, which can effectively prevent the drive motor from burning out due to excessive torque.

[0023] (5) The roll material is wound in an “S” shape on the roller for guidance when the roll material is wound. During the winding process, larger foreign objects on the surface of the roll material can be removed by winding in an “S” shape on the roller. Attached Figure Description

[0037] like Figure 1 and Figure 2 As shown, an electric laying and winding vehicle includes a frame 1, front and rear axles and a steering structure 2, a tail plate 3, an electric laying and winding device 4, and a control box 5. The frame 1 includes a bottom plate 6, a front step 7, a square tube frame 8, a tail plate 9, and a tail plate frame 10. The front and rear axles and the steering structure 2 are welded to the bottom of the frame 1, the control box 5 is welded inside the square tube frame 8, and the electric laying and winding device 4 is connected to the square tube on the bottom plate 6 through a shaft fixing seat. The tail plate 3 is movably connected to the bottom plate 6.

[0038] The bottom plate, front pedal, and rear pedal are all made of steel plates.

[0039] A metal sleeve is welded to one end of the rear pedal frame 10, and a metal sleeve is welded to the end of the frame 1 near the control box 5. The rotating shaft is simultaneously fitted into the two metal sleeves, causing the square tube frame 8 to rotate around the rotating shaft. The rear pedal 9 is welded to the rear pedal frame 10. The bottom plate 6 and the front pedal 7 are both welded and fixed to the square tube frame 8. When the vehicle is laying, the staff stands on the rear pedal frame 10, facing the direction of the vehicle's travel, which facilitates the staff to observe the actual laying status. When the vehicle is rewinding, the staff can stand on the front pedal steel plate, still facing the direction of the vehicle's travel, to ensure that the vehicle rewinds along the roll laying direction, which facilitates the staff to control the direction of the vehicle's travel.

[0040] like Figure 3 As shown, the bottom plate 6 is equipped with a limiting square tube 6-1, a limiting structure 6-2, a mounting block 6-3, and a gap 6-4. The limiting square tube 6-1 consists of two sets of square tubes welded side by side on the bottom plate 6. When the laying and winding device 4 is installed or removed by rolling along the tail plate 3 and the bottom plate 6, the limiting square tube 6-1 prevents deviation during the rolling process. The limiting structure 6-2 consists of two vertical square tubes welded to the bottom plate 6 with a distance of 15mm between them, preventing the laying and winding device 4 from deviating to the left or right when rotating. The mounting block 6-3 is fixedly installed on the bottom plate 6, and the laying and winding device 4 is fixed to the bottom plate 6 by the mounting block 6-3.

The torque limiter 32 is connected and is an adjustable torque limiter 32 used to prevent the motor from burning out due to overload. When the drive shaft 21 is stuck or the winding drum 19 is overloaded, causing the adjustable torque limiter 32 to exceed a certain torque, the adjustable torque limiter 32 will idle and will no longer provide driving force to the drive shaft 21 to prevent the drive motor from burning out. The friction rubber 36 is sleeved on the drive shaft 21 and contacts the winding drum 19, thereby driving the rotation of the winding drum 19. The chain 31 passes through the gap 6-4 to drive the laying and winding device 4 to rotate.

[0042] Figure 7As shown, the front and rear axles and steering structure 2 include a rear axle 11, a front axle 12, a steering structure 13, and a brake control line 14; the rear axle 11 is used for driving the vehicle, the steering structure 13 controls the steering of the front axle 12, and the brake control line 14 is connected to the rear axle 11 for braking the rear axle 11; the drive motor 30 is directly integrated on the rear axle 11, forming a single structure with the rear axle 11, and is used for driving the vehicle.

[0043] Figure 8 As shown, the steering structure 13 includes a rearview mirror 26, a steering wheel 27, a steering rod 28, and a steering assist 29. The rearview mirror 26 and the steering wheel 27 are both fixed to the crossbar at the top of the steering rod 28. The lower end of the steering rod 28 is connected to the steering assist 29, which is a spring-hydraulic rod. When the steering wheel 27 is turned, the spring-hydraulic rod provides assistance, making steering easier.

[0044] Figure 9 As shown, the tail plate 3 includes rollers 15, rollers 16, pads 17, and a tail plate frame 18; the pads 17 are welded to the tail plate frame 18; the rollers 15 are installed on the side of the tail plate frame 18 away from the rollers 16 by screws, and one roller is installed at each of the two corners of the tail plate frame 18. When the tail plate falls, the rollers 15 contact the ground, supporting the tail plate and facilitating the rolling and transportation of the roll material; the rollers 15 are fixed to the side of the tail plate frame 18 away from the rollers.

[0045] The number of rollers 16 is 2 to 4. The roll material is wound in an "S" shape on the rollers 16, which is used to guide the roll material when it is being wound up, and at the same time removes larger foreign objects from the surface of the roll material.

[0046] like Figure 10 As shown, the control box 5 includes an operation panel 22, a mounting plate 23, a battery pack 24, and a control box sealing plate 25; the control switch is mounted on the mounting plate 23; the operation panel 22 has pre-drilled corresponding holes, and the control switch protrudes from the operation panel 22 for easy operation; the battery pack 24 is placed inside the control box 5 for power supply to the entire vehicle; the entire control box 5 is encapsulated by 8 control box sealing plates 25, including two sealing plates on the front side, two sealing plates on the rear side, one sealing plate on the left side, one sealing plate on the right side, and two sealing plates on the bottom. The 8 control box sealing plates 25 are welded and mounted on the frame 1 inside the square tube frame 8.

[0047] like Figure 11As shown, four square tubes 1-a extend downward from the frame 1. The ends of the square tubes 1-a are welded to the front and rear axles and the steering structure 2 at part 2-a, fixing the front and rear axles and the steering structure 2 to the frame 1, realizing the vehicle's forward, reverse, and steering functions. Two metal sleeves are welded to part 1-b of the frame 1, and two metal sleeves are correspondingly welded to part 3-b of the tailplate 3. The pivot is simultaneously fitted into part 1-b of the frame 1 and part 3-b of the tailplate 3, enabling the tailplate 3 to rotate at the rear of the frame 1. When the vehicle is being laid or rolled up, the tailplate rolls up. When it is necessary to replace the roll material during the laying process or during the rolling process, the tailplate rolls up. When changing a fully wound roll, the tail plate drops down to push the roll up and down; section 1-c of frame 1 consists of two horizontal square tubes, and section 4-c of the electric laying and winding device 4 is a shaft fixing seat. The shaft fixing seat is placed on the horizontal square tubes and fixed with screws passing through the square tubes; section 1-d of frame 1 has six vertical square tubes, and the metal cover plate of section 5-d of control box 5 is fixed to the square tubes by welding. Various control switches are installed inside control box 5; section 1-e of frame 1 is used for the installation of drive equipment. The drive motor mounting plate is fixed to the square tubes of section 1-e of frame 1 with screws.

[0048] The drive motor 30 drives the adjustable torque limiter 32 to rotate via the chain 31. When the torque does not exceed the load, the adjustable torque limiter 32 transmits power to the winding drum 19 through the friction rubber 36 on the drive shaft 21, driving the winding drum to rotate and realize the winding and laying of the paving vehicle. When the torque exceeds the load, the adjustable torque limiter idles and the power is no longer transmitted downward to prevent the motor from burning out due to excessive load.

[0049] When the drive motor 30 rotates clockwise, it drives the take-up roller 19 to complete the laying process. When the drive motor 30 rotates counterclockwise, it drives the take-up roller 19 to complete the winding process. If there is jamming during the transmission process, or if the load on the take-up roller 19 is too large during the laying and winding of the roll material, the adjustable torque limiter 32 will automatically disconnect the power transmission due to excessive torque. The adjustable torque limiter 32 will automatically idle, effectively preventing the drive motor 30 from burning out due to excessive torque.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
