Description

Technical Field

[0001] This utility model relates to the technical field of tarpaulin spreading implementation device, and in particular to an automatic tarpaulin device for large vehicles. Background Technology

[0002] In large vehicle production workshops, space is generally limited, making it difficult to install traditional, large-footprint automated tarpaulin covering and installation equipment. Furthermore, large automated installation equipment requires drivers to drive vehicles into the designated work area, resulting in cumbersome procedures and wasted space. Currently, most large vehicle production workshops use manual tarpaulin covering, with some operators climbing onto the top of the vehicles while others assist from the ground. This method not only poses safety hazards for operators working on top of vehicles but also requires a large workforce, leading to increased labor costs, low efficiency, and wasted time. Utility Model Content

[0003] In view of the above problems, this utility model designs a novel automatic tarpaulin spreading / rolling device more suitable for large vehicles. This device is movable due to a walking mechanism at the bottom, and a wireless controller controls the lifting mechanism to automatically rise to a height matching the vehicle. Simultaneously, it controls the sliding of two slider mechanisms on the crossbeam along the guide rails to match the corresponding vehicle width. The automatic rolling and spreading of the tarpaulin is achieved through the coordinated operation of these mechanisms. When not in use, this utility model can also be reduced to a minimum size to save space.

[0004] Specifically, this utility model discloses an automatic tarpaulin device for large vehicles, which mainly includes: a traveling mechanism, a lifting mechanism, and a crossbeam assembly. The traveling mechanism is used for moving the device on the ground; the lifting mechanism is mounted on the traveling mechanism and extends or retracts to raise or lower the crossbeam assembly to its working height or minimum height; the crossbeam assembly is located above the lifting mechanism and has a sliding mechanism, the slider of which connects to the tarpaulin and slides to allow the tarpaulin to reach the width position of the vehicle.

[0005] The lifting mechanism includes two hydraulic cylinders (e.g., three-stage hydraulic cylinders) and two matching hydraulic base stations. The hydraulic base stations are located on the traveling mechanism and connected above the matching hydraulic cylinders. The upper part of the hydraulic cylinders is connected to both ends of the crossbeam of the crossbeam assembly, and their synchronous extension and retraction drive the crossbeam to the working height or minimum height.

[0006] The traveling mechanism includes at least two caster wheel assemblies, preferably four or more. Each caster wheel assembly mainly consists of casters and a connecting base. The casters are used to move the device to the desired location and to move along the length of the vehicle when spreading or rolling up the tarpaulin; the connecting base is used to connect the casters to the bottom of the lifting mechanism (the bottom of the hydraulic base station). Preferably, at least two caster wheel assemblies are provided at the bottom of each hydraulic base station.

[0007] Furthermore, the caster wheel assembly also includes a support base and a pedal that cooperate with the caster wheel. The pedal controls the support base to move away from or to the ground. Preferably, when the lifting mechanism extends or retracts, the support base is lowered to the ground by the pedal, providing further support for the extension or retraction. Preferably, each caster wheel is equipped with a support base and a pedal. Alternatively, support bases and pedals may be provided on some of the caster wheels.

[0008] The crossbeam assembly includes a crossbeam and a sliding mechanism arranged along the crossbeam. The sliding mechanism includes a slide rail and two sliders; the sliders engage with the slide rail to move along the slide rail.

[0009] Furthermore, the slide rails are two rack slide rails arranged along both sides of the crossbeam. The crossbeam preferably has a rectangular or square cross-section, with grooves on both the left and right sides for embedding and installing the rack slide rails.

[0010] Furthermore, the slider includes a housing, meshing gears, and a horizontal motor. The meshing gears mesh with the rack and pinion rail gears, and the slider moves along the rack and pinion rails under the drive of the horizontal motor. Preferably, each slider has two meshing gears and two horizontal motors, with the meshing gears meshing with the two rack and pinion rails from both sides to achieve meshing and clamping the crossbeam.

[0011] Furthermore, the slider also includes a rope, pulleys or rollers, and a vertical motor. One end of the rope (the free end) is used to connect to the tarpaulin, and the other end is connected to the pulley or roller; the vertical motor drives the rotation of the pulley or roller, thereby raising or lowering the tarpaulin. The pulleys or rollers of the two sliders are preferably arranged opposite each other (extending towards the vehicle), but they can also be arranged back to back (both extending towards the lifting mechanism).

[0012] Alternatively, the housing has a through-hole for the rack and pinion guide rail to pass through and a chamber for accommodating the horizontal and vertical motors. The drive end of the horizontal motor extends out of the chamber and connects to a meshing gear within the through-hole; the horizontal and vertical motors are arranged perpendicularly to each other; the drive end of the vertical motor extends out of the chamber and connects to a pulley or roller. From an installation convenience perspective, the housing can be machined into two parts split in the middle, each part having half a chamber and half a through-hole, facilitating the covering of the crossbeam for rack and pinion gear meshing installation; the joined part has a vertical motor mounting slot and shaft hole for securing and mounting the vertical motor.

[0013] In addition, the device also includes a wireless controller for controlling the operation of various components of the lifting mechanism (cylinder) and the beam assembly (motor).

[0014] This utility model provides an automatic tarpaulin device for large vehicles. Structurally, the device has two lifting three-stage hydraulic cylinders that control the vertical raising and lowering of the equipment to adjust it to a suitable tarpaulin covering height for the corresponding vehicle. The hydraulic cylinders can reach a height of 1500mm when fully retracted and 4200mm when fully extended. Two hydraulic base stations, each 100mm high, are installed below the two hydraulic cylinders. Below each hydraulic base station, at least two casters are provided for the movement of the device, and each caster has a mechanical lifting and fixing device to ensure smoother operation. Preferably, a 90mm square crossbeam is installed at the top of the device, fixed to the top of the two three-stage hydraulic cylinders. Two racks are located on the left and right sides of the crossbeam. The racks engage with gears on the sliders to allow the sliders to move freely on the crossbeam, thereby adjusting the distance between the two sliders to match the vehicle width. The device comprises two opposing sliders, each consisting of a metal housing, two gears meshing with a rack and pinion, two horizontal motors controlling the gear movement, and a motor and pulleys or rollers controlling the retraction or expansion of the tarpaulin. It is also equipped with a wireless controller and power wiring. When fully extended, the device reaches a height of 4500mm and a controllable retraction width of 3700mm, making it suitable for covering most large vehicles with tarpaulins. In its retracted state, the device measures 1830mm in height and 4000mm in width. Attached Figure Description

Detailed Implementation

[0026] The following description, in conjunction with the accompanying drawings, further illustrates the "Automatic Canopy Device for Large Vehicles" of this utility model.

[0027] See Figure 1-10 This utility model provides an automatic tarpaulin device for large vehicles, wherein... Figure 5 Except for Embodiment 2, which uses roller 11 as a means of connecting / winding tarpaulin, the other figures show Embodiment 1, which uses positioning pulley 8 as a means of connecting tarpaulin.

[0028] Example 1

[0029] See Figure 1-4 This utility model discloses an automatic tarpaulin device for large vehicles, which mainly consists of three parts: a walking mechanism, a lifting mechanism, and a crossbeam assembly. The device includes: a power cord 1, a caster wheel assembly, a hydraulic base station 2, a three-stage hydraulic cylinder 3, a wireless controller 4, a crossbeam 5, a rack and pinion slide rail 6, and a slider 7.

[0030] The walking mechanism includes four caster wheel assemblies. Preferably, each caster wheel assembly includes caster wheels 9, a connecting base 21, a support base 12, and a pedal 13. The connecting base 21 connects the assembly to the bottom of the hydraulic base station 2. The pedal 13 controls the raising and lowering of the support base 12. When the three-stage hydraulic cylinder 3 needs to extend or retract, the pedal 13 is preferably used to lower the support base 12 to the ground, achieving stable support for the entire device. The pedal 13 can also be configured to control the support base 12 to further raise the caster wheels 9 (e.g., ...). Figure 6 (as shown in the image).

[0031] The lifting mechanism includes two three-stage hydraulic cylinders 3 and two matching hydraulic base stations 2. The hydraulic base stations 2 are located on the traveling mechanism and connected above the matching three-stage hydraulic cylinders 3; the upper part of the three-stage hydraulic cylinders 3 is connected to both ends of the crossbeam 5, and the crossbeam 5 is driven to the working height or minimum height through their synchronous extension and retraction.

[0032] The crossbeam assembly includes a crossbeam 5, a rack and pinion slide rail 6, and two sliders 7. The crossbeam 5 has a square cross-section and grooves on both the left and right sides for embedding and mounting the rack and pinion slide rail 6.

[0033] Further, see Figure 7-9 The slider 7 includes a housing, two meshing gears 10, two horizontal motors 16, a pulley 8, a vertical motor 17, and a rope (not shown). The meshing gears 10 mesh with the rack and pinion rails 6, enabling the slider 7 to move along the rack and pinion rails 6 under the drive of the horizontal motors 16. The two meshing gears 10 mesh with the two rack and pinion rails 6 from both sides respectively, to achieve meshing and clamping the crossbeam 5. One end (free end) of the rope is used to connect to the target tarpaulin, and the other end is connected to the pulley 8; the vertical motor 17 drives the pulley 8 to rotate, thereby driving the rope to raise or lower the tarpaulin.

[0034] Alternatively, the housing has a through-hole 14 for the rack and pinion rail 6 to pass through and a chamber 15 for accommodating a horizontal motor 16 and a vertical motor 17. The drive end of the horizontal motor 16 extends out of the chamber 15 and connects to a meshing gear 10 within the through-hole 14; the horizontal motor 16 and the vertical motor 17 are arranged perpendicularly to each other; the drive end of the vertical motor 17 extends out of the chamber 15 and connects to a pulley 8. For ease of installation, the housing can be fabricated as two separate assembly blocks 18, see [reference needed]. Figure 9 The two assembly blocks 18 are mirror-symmetrically arranged, each with half a chamber and half a through hole, which facilitates the meshing and installation of the rack and pinion gears on the beam 5. The closing part is provided with a mounting slot and shaft hole for the vertical motor 16, which is used to lock and install the vertical motor 16.

[0035] In addition, the device also includes a wireless controller 4, see [link to documentation]. Figure 10The example diagram shows various buttons used to control the operation of the lifting mechanism (cylinder) and the crossbeam assembly (motor). The control panel can be equipped with buttons such as: equipment start button, equipment emergency stop button, hydraulic cylinder up button, hydraulic cylinder down button, right slider right movement button, right slider left movement button, left slider left movement button, left slider right movement button, double slider transverse pulley forward rotation button, and double slider transverse pulley reverse rotation button.

[0036] Example 2

[0037] As described above, another embodiment of the automatic tarpaulin device for large vehicles provided by this utility model is an example of setting roller 11. See also Figure 5 In this embodiment, except that the pulley 8 is replaced with the roller 11, all other settings are the same as in Embodiment 1.

[0038] This utility model provides an automatic tarpaulin covering device for large vehicles. The hydraulic cylinders have a height of 1500mm when fully retracted and 4200mm when fully extended. Two hydraulic base stations, each 100mm high, are installed below the two hydraulic cylinders. Furthermore, the device can reach a height of 4500mm when fully extended, with a controllable extension width of 3700mm, making it suitable for covering most large vehicles with tarpaulins. In the retracted state, the device has a height of 1830mm and a width of 4000mm.

[0039] Furthermore, the present invention provides a method 1 for using an automatic tarpaulin device for large vehicles: single use (for vehicles with short lengths).

[0040] In operation, the operator first connects the device to the power supply and secures both ends of the tarpaulin in the desired width direction to the two sliders 5 using ropes. (Alternatively, the operator can remove the horizontal pulleys 8 (Example 1) from the two sliders 5 and replace them with rollers 11 of the appropriate length (Example 2), also connected to the rollers 11 via ropes.) Press the start button and adjust the width between the two sliders 7 using the wireless controller 4 according to the vehicle's width, and adjust the extension of the two three-stage hydraulic cylinders 3 according to the vehicle's height to match the vehicle's height. The two horizontal pulleys 8 rotate to raise the tarpaulin to the corresponding height, and the device lock button is pressed. After completing the above steps, the operator pushes the device from the rear to the front of the vehicle. Due to the weight of the tarpaulin, it can cover large vehicles. After covering, the device is lowered to the lowest possible height without touching the vehicle equipment. The ropes securing the tarpaulin to the pulleys are untied, the device is pushed out from the front of the vehicle, and the operator secures the tarpaulin to the ground.

[0041] In addition, this utility model provides a second method for using an automatic tarpaulin device for large vehicles: two devices are used together (for vehicles with a long length, such as special vehicles).

[0042] In operation, the operator first connects both devices to the power supply. Using the rollers 11 of the corresponding length as described in Example 2, the tarpaulin is connected to the rollers 11 via ropes. Pressing the start button controls the movement of the rollers 11 by controlling the horizontal motors 16 on the two sliders 7 on each device. This causes the rollers 11 to move in opposite directions, rolling up the tarpaulin. The width between the two sliders 7 is adjusted using the wireless controller 4 according to the vehicle's width, and the two three-stage hydraulic cylinders 3 are extended and adjusted to match the vehicle's height. The two horizontal rollers 11 rotate, raising the tarpaulin to the appropriate height. The operator then moves the device from the front to the rear of the vehicle. Yes, the operator controls the two devices separately. The operator steps down the mechanical lifting device on the universal wheel 9 of the rear device. When the operator pushes the device forward, the wireless controller 4 controls the horizontal motor 16 on the two sliders 7 of each device to control the movement of the roller 11. The rollers 11 of the two devices move in opposite directions to unfold the tarpaulin. After the device is pushed to the designated position and the covering is completed, the two devices are lowered to the lowest height without touching the vehicle equipment. The ropes on the rollers are untied, the device is pushed out from the front of the vehicle, and the operator secures the tarpaulin to the ground.
