Description

Technical Field

[0001] This invention belongs to the field of cargo transfer, and specifically relates to a vehicle-mounted multi-directional mobile hoisting mechanism. Background Technology

[0002] In a wide range of scenarios such as small and medium-sized cargo transportation, emergency repairs, and retail replenishment, loading goods from the ground or platform into the cargo compartment of a transport vehicle is a basic but arduous physical task. The most primitive method of operation relies entirely on manual labor for handling, which is inefficient and poses safety hazards.

[0003] To overcome the drawbacks of purely manual handling, vehicle-mounted lifting or handling mechanisms have emerged. These mechanisms involve installing a retractable boom on a vehicle, extending the boom out of the cargo hold to clamp and lift goods, and then retracting the boom back into the cargo hold for unloading. Generally, when goods are large, it's difficult to lift them by gripping their sides with the claws; the goods need to be secured with lashing ropes before lifting. For smaller goods, lashing is unnecessary, and they can be directly gripped with the claws. However, selecting the appropriate lifting equipment based on the goods requires manual judgment and adjustment, especially during mixed loading operations. This necessitates frequent equipment changes, disrupting the continuity of operations and wasting time and effort. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vehicle-mounted multi-directional mobile lifting mechanism to solve the problem of operators having to frequently change lifting tools, interrupting the continuity of operations, and wasting time and effort when encountering mixed loading operations.

[0005] According to embodiments of the present invention, the present invention adopts the following technical solution:

[0006] The vehicle-mounted multi-directional mobile lifting mechanism includes a lifting assembly, a drive assembly for moving the lifting assembly, and a control assembly. The drive assembly includes a transverse slide rail fixed to the top of the vehicle compartment, a longitudinal slide rail slidably connected to the transverse slide rail, and a mounting arm mounted on the longitudinal slide rail. When the mounting arm slides on the longitudinal slide rail, the end of the mounting arm has two states: inside the vehicle compartment and outside the vehicle compartment. The lifting assembly includes a mounting plate, a hook, a first drive component mounted on the mounting plate for driving the hook to move vertically, a gripper, and a second drive component mounted on the mounting plate for driving the gripper to move vertically. The mounting plate is rotatably connected to the end of the mounting arm, and the rotation axis of the mounting plate is vertical. The control assembly includes a controller and a camera mounted on the mounting plate. The camera is used to photograph the cargo. The camera, the first drive component, and the second drive component are all signal-connected to the controller. The controller receives the photographing data from the camera and selects to control the operation of the first drive component or the second drive component based on the photographing data. The controller also controls the sliding position of the mounting arm and the longitudinal slide rail based on the photographing data, controlling the lifting assembly to be directly above the cargo.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. By positioning the goods through a camera, the hoisting components can be automatically controlled to be positioned directly above the goods. After the goods are transported outside the vehicle, there is no need for manual adjustment of the goods' placement or manual control of the hoisting components. The camera is positioned downwards to capture the goods and center them in the frame, ensuring that the hoisting components are positioned directly above the goods.

[0009] 2. When the goods are located in the center of the camera's field of view, the captured state of the goods can clearly indicate their size. Based on the size of the goods, it is possible to choose whether to use a hook or a gripper for lifting. When the goods are large, the controller controls the first drive unit to lower the hook and then lift the goods using the hook. When the goods are small, the controller controls the second drive unit to lower the gripper and then lift the goods using the gripper.

[0010] In this solution, the camera system enables the positioning of the lifting components and determines whether to use a hook or a gripper for lifting, thus ensuring the rationality and safety of the lifting operation.

[0011] 3. By extending the mounting arm outside the vehicle compartment or sliding it back inside, goods can be hoisted from the outside into the compartment or from inside the compartment to the outside. The longitudinal slide rail can slide relative to the transverse slide rail, which facilitates the adjustment of the position of the goods entering the compartment. The mounting plate is rotatably mounted on the mounting arm, which facilitates the adjustment of the hoisting angle of the goods or the adjustment of the hoisting components to hoist the goods at a suitable angle.

[0012] Furthermore, the control assembly also includes a distance sensor mounted on the mounting plate, which is used to detect the distance between the lower surface of the mounting plate and the cargo; the distance sensor and the controller are signal connected, and the controller is used to receive the distance signal from the distance sensor and control the downward movement of the first drive member or the second drive member according to the distance signal.

[0013] Furthermore, the control assembly also includes a first detection element installed at the bottom of the vehicle compartment. The first detection element is used to detect whether the position height of the cargo is higher than the bottom of the vehicle compartment. The first detection element is signal-connected to the controller, which is used to receive the detection signal from the first detection element and control the upward movement of the first drive element or the second drive element according to the detection signal.

[0014] Furthermore, the control assembly also includes a second detection element installed on one side wall of the cabin. The second detection element is used to detect whether the side of the cargo extends beyond the side wall of the cabin. The second detection element is signal-connected to the controller, which is used to receive the detection signal from the second detection element and control the sliding position of the longitudinal slide rail according to the detection signal.

[0015] Furthermore, the control assembly also includes a third detection element installed at the cargo inlet / outlet end of the vehicle compartment. The third detection element is used to detect whether cargo has entered the vehicle compartment. The third detection element is signal-connected to the controller, which is used to receive the detection signal from the third detection element and control the sliding position of the mounting arm according to the detection signal.

[0016] Furthermore, the first and second driving components are arranged side by side, and a sliding rod is slidably connected between the first and second driving components on the mounting plate. A baffle is fixed at the lower end of the sliding rod, and the longitudinal section of the baffle and the sliding rod is an inverted T-shape. When the sliding rod is located in the middle of the first and second driving components, both the first and second driving components are located above the baffle. When the slide plate slides towards the first driving component, the baffle is no longer located below the second driving component, and when the slide plate slides towards the second driving component, the baffle is no longer located below the first driving component.

[0017] Furthermore, the first driving component includes a winch fixed to the mounting plate and a lifting rope wound on the output shaft of the winch, with a hook fixed to the end of the lifting rope; the first driving component also includes a first weight sensor mounted on the output shaft of the winch, the first weight sensor being used to detect the gravity borne by the output shaft of the winch.

[0018] Furthermore, the second driving member includes a driving rod that extends or slides vertically, with a gripper mounted at the end of the driving rod; the second driving member also includes a second weight sensor mounted on the driving rod, the second weight sensor being used to detect the gravity borne by the driving rod.

[0019] Furthermore, it also includes a support assembly, which includes a vertical support that is slidably connected to the outer wall of the vehicle compartment and a horizontal support that is slidably connected to the bottom of the vertical support. The horizontal support is used to provide support for the cargo at the bottom of the cargo.

[0020] Furthermore, the gripper includes two clamping plates that are laterally slidably connected to the drive rod, with rubber pads installed on the opposite sides of the two clamping plates; pressure sensors are installed on the opposite sides of the two clamping plates.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments are given.

[0026] like Figure 1 , Figure 2 As shown, the vehicle-mounted multi-directional mobile hoisting mechanism includes a hoisting assembly, a drive assembly for driving the hoisting assembly to move, and a control assembly.

[0027] Combination Figure 3 As shown, the drive assembly includes a transverse slide rail 1 fixed to the top of the cabin 6, a longitudinal slide rail 4 slidably connected to the transverse slide rail 1, and a mounting arm 5 mounted on the longitudinal slide rail 4. Generally, the cargo 9 entry and exit opening of the cabin 6 is located at the rear end of the vehicle. With the direction of the entry and exit opening as the longitudinal direction, that is, the length direction of the vehicle as the longitudinal direction, and the direction perpendicular to the longitudinal direction as the transverse direction, the transverse slide rail 1 referred to in this embodiment is along the width direction of the vehicle.

[0028] The transverse slide rail 1 is directly fixed to the top of the cabin 6. The longitudinal slide rail 4 includes a mounting shell 2 that is slidably connected to the transverse slide rail 1 and a track part 3 set in the mounting shell 2. The top of the cabin 6 is also equipped with a drive structure for driving the longitudinal slide rail 4 to slide. The drive structure is a conventional device in the prior art that can realize reciprocating linear motion, such as a cylinder (or hydraulic cylinder) or a screw structure (the motor drives the screw to rotate, and the screw and the mounting shell 2 are threadedly connected to realize the sliding of the longitudinal slide rail 4).

[0029] A drive structure for sliding the mounting arm 5 of the drive rod 12 is installed on the longitudinal slide rail 4. The drive structure is a conventional device in the prior art that can realize reciprocating linear motion, such as a cylinder (or hydraulic cylinder) or a lead screw structure (the motor drives the lead screw to rotate, and the lead screw and the mounting arm 5 are threadedly connected to realize the sliding of the mounting arm 5). When the mounting arm 5 slides on the longitudinal slide rail 4, the end of the mounting arm 5 has two states: located inside the vehicle compartment 6 and extended outside the vehicle compartment 6.

[0030] The hoisting assembly includes a mounting plate 15, a hook 17, a first drive component mounted on the mounting plate 15 for driving the hook 17 to move vertically, a gripper, and a second drive component mounted on the mounting plate 15 for driving the gripper to move vertically. Specifically, the mounting plate 15 is rotatably connected to the end of the mounting arm 5, and the rotation axis of the mounting plate 15 is vertical. A motor for driving the mounting plate 15 to rotate is mounted on the mounting arm 5. The output shaft of the motor can be directly fixed to the mounting plate 15, or the mounting plate 15 can be driven to rotate through conventional transmission methods such as gear transmission.

[0031] The first driving component includes a winch 13 fixed on the mounting plate 15 and a lifting rope 16 wound on the output shaft of the winch 13. A hook 17 is fixed to the end of the lifting rope 16. The winch 13 winds up or releases the lifting rope 16, thereby realizing the vertical movement of the hook 17. The second driving component includes a driving rod 12 that can extend or slide vertically. A gripper is installed at the end of the driving rod 12. In this embodiment, the driving rod 12 is an electric telescopic rod. In actual design, a cylinder-driven sliding rod can also be used as the driving rod 12.

[0032] The gripper includes two clamping plates 10 that are laterally slidably connected to the drive rod 12. Specifically, a connecting plate 11 is fixed to the end of the drive rod 12, and the clamping plates 10 are slidably connected to the connecting plate 11. A drive structure for driving the clamping plates 10 to slide is installed on the connecting plate 11. The drive structure is a conventional device in the prior art that can realize reciprocating linear motion, such as a cylinder (or hydraulic cylinder) or a lead screw structure (the motor drives the lead screw to rotate, and the lead screw and the clamping plate 10 are threadedly connected to realize the sliding of the clamping plates 10). When the two clamping plates 10 slide towards each other, the goods 9 are gripped; when the two clamping plates 10 slide away from each other, the goods 9 are released. Rubber pads are installed on the opposite sides of the two clamping plates 10. The rubber pads prevent damage to the goods 9 caused by excessive rigid clamping force and also have an anti-slip effect. In actual design, pressure sensors are installed on the opposite side of the two clamping plates 10. The clamping force of the clamping plates 10 on the cargo 9 can be detected by the pressure sensors to avoid excessive or insufficient clamping force.

[0033] The control components include a controller and a camera 22 mounted on the mounting plate 15. Figure 2 The image shows the camera 22 mounted on the lower end of the baffle 14. When the baffle 14 is not installed, the camera 22 can be installed in the area between the electric telescopic rod and the winch 13. The camera 22 is used to photograph the goods 9. The camera 22, the first drive unit, and the second drive unit are all connected to the controller signal. Specifically, the controller can be a microcontroller (MCU), a programmable logic controller (PLC), or other existing technologies, and the camera 22 is an industrial CCD / CMOS camera from the existing technology.

[0034] The controller receives the shooting data from the camera 22 and selects to control the operation of the first or second drive component based on the shooting data. The controller also controls the sliding position of the mounting arm 5 and the longitudinal slide rail 4 based on the shooting data, controlling the lifting assembly to be directly above the cargo 9. Specifically, the controller is signal-connected to the winch 13 used for the first drive component, and the controller is signal-connected to the electric telescopic rod of the second drive component. The controller is also signal-connected to each drive structure used to drive the sliding of the mounting arm 5, the longitudinal slide rail 4, and the clamping plate 10.

[0035] In the initial state, the longitudinal slide rail 4 is stored near the side wall of the compartment 6, the mounting arm 5 is located inside the compartment 6, and the hook 17 and gripper are also stored near the mounting arm 5 to minimize the impact on the placement of goods 9 inside the compartment 6. When it is necessary to load or unload goods 9, taking the transfer of goods 9 from the ground to the compartment 6 as an example, the staff transports goods 9 to the ground near the rear opening of the compartment 6.

[0036] The drive mounting arm 5 slides out of the compartment 6, and the camera 22 takes an initial picture. Based on the position of the cargo 9 in the first picture, that is, based on the direction of the cargo 9 in the picture, the drive mounting arm 5 and the longitudinal slide rail 4 slide until the mounting plate 15 is directly above the cargo 9.

[0037] At this point, camera 22 takes a second picture. Based on the position of goods 9 in the second picture, it again determines whether goods 9 is centered in the frame. High-precision centering is not required here; approximate centering is sufficient. If it is not centered, the mounting arm 5 and longitudinal slide rail 4 are driven to slide again, and a third picture is taken for further judgment. The following description assumes that goods 9 is already centered in the second picture.

[0038] Then, based on the dimensions of cargo 9 in the second image taken after the shooting, since cargo 9 is basically centered, its size can be determined by the total area it occupies in the image. When the total area occupied by cargo 9 exceeds the set limit, the controller activates the winch 13, lowering the hook 17. Larger cargo 9 items need to be secured beforehand by workers. After the hook 17 is lowered, workers simply hook it onto the securing rope. Then, the winch 13 drives the rope 16 to wind up, and after the hook 17 lifts cargo 9, the drive arm 5 retracts into the compartment 6, allowing cargo 9 to be transferred into the truck.

[0039] When the area occupied by cargo 9 in the image is less than a set value, the controller activates the electric telescopic rod, lowering the gripper. After the gripper is lowered, the drive plate 10 slides to grip cargo 9. Then, the electric telescopic rod drives the gripper to rise, retracting the mounting arm 5 into the compartment 6, allowing cargo 9 to be transferred into the vehicle. When using the gripper, based on the angle of cargo 9 in the second image taken, the controller can also activate the motor of the drive plate 15, rotating it to a certain angle to match the angle of cargo 9, facilitating gripping. After gripping, the controller then controls the mounting plate 15 to rotate back to its original position.

[0040] In another embodiment of the invention, to facilitate control of the downward stroke of the hook 17 or gripper, the control assembly further includes a distance sensor mounted on the mounting plate 15. The distance sensor is used to detect the distance between the lower surface of the mounting plate 15 and the cargo 9. The distance sensor can be an existing ultrasonic ranging sensor, which detects the distance by transmitting sound wave signals. The distance sensor and the controller are connected by a signal connection. The controller receives the distance signal from the distance sensor and controls the downward stroke of the first or second drive member based on the distance signal.

[0041] In practical use, after the camera 22 takes a second picture and determines that the goods 9 are in the center of the second picture, the controller first controls the distance sensor to measure the distance. Based on the distance sensor's measurement signal, the controller determines how far the hook 17 or gripper needs to be lowered to complete the lifting or clamping. The controller then controls the lowering stroke of the winch 13 or electric telescopic rod. Once the lowering stroke is reached, the lifting or clamping can be easily completed.

[0042] In another embodiment of the present invention, in order to facilitate the placement and stacking of goods 9 after they are transferred into the compartment 6, the control component further includes a first detection element 18 installed at the bottom of the compartment 6. The first detection element 18 is used to detect whether the position height of goods 9 is higher than the bottom of the compartment 6. Specifically, the first detection element 18 is an ultrasonic ranging sensor. The probe of the ultrasonic ranging sensor faces outward from the compartment 6. When there are no goods 9 obstructing the ultrasonic ranging sensor, the ultrasonic ranging sensor detects the sound wave signal reflected back from the outdoor structure. When goods 9 obstruct the ultrasonic ranging sensor, the sound wave signal reflected back from the surface of goods 9 can be detected. Specifically, the distance signal is different, so it can be determined whether goods 9 obstruct the ultrasonic ranging sensor.

[0043] The first detection element 18 is connected to the controller signal. The controller is used to receive the detection signal from the first detection element 18 and control the upward movement of the first drive element or the second drive element according to the detection signal. Specifically, during the upward lifting process of the cargo 9, the ultrasonic ranging sensor first detects the sound wave signal reflected back from the outdoor structure, then detects the sound wave signal reflected back from the surface of the cargo 9, and finally changes back to the sound wave signal reflected back from the outdoor structure. This signal change is reflected in two relatively obvious changes in the distance signal detected by the ultrasonic ranging sensor. When the second obvious change occurs, it can be determined that the bottom height of the cargo 9 has exceeded the bottom of the cabin 6, and the winch 13 or the electric telescopic rod can be closed. Then, the cargo 9 can be transported into the cabin 6 by driving the mounting arm 5 to slide.

[0044] The control assembly also includes a second detection element 19 installed on one side wall of the cabin 6. The second detection element 19 is used to detect whether the side of the cargo 9 extends beyond the side wall of the cabin 6. Specifically, the second detection element 19 is also an ultrasonic ranging sensor. The probe of the ultrasonic ranging sensor faces outward from the cabin 6. When there is no cargo 9 obstructing the ultrasonic ranging sensor, the ultrasonic ranging sensor detects the sound wave signal reflected back from the outdoor structure. When the cargo 9 obstructs the ultrasonic ranging sensor, the sound wave signal reflected back from the surface of the cargo 9 can be detected. Specifically, the distance signal is different, so it can be determined whether the cargo 9 obstructs the ultrasonic ranging sensor.

[0045] The second detection element 19 is connected to the controller. The controller receives the detection signal from the second detection element 19 and controls the sliding position of the longitudinal slide rail 4 according to the detection signal. Specifically, the cargo 9 has been raised to a position slightly higher than the bottom of the cabin 6 by the detection of the first detection element 18. At this time, the longitudinal slide rail 4 is driven to slide, so that the cargo 9 moves laterally outside the cabin 6. The ultrasonic ranging sensor detects the sound wave signal reflected back from the outdoor structure. When the cargo 9 moves to a position that obstructs the ultrasonic ranging sensor, the detection signal of the ultrasonic ranging sensor changes significantly. This indicates that the position of the cargo 9 is close to the edge of the cabin 6 and the edge of the cargo 9 slightly exceeds the edge of the cabin 6. Then, the longitudinal slide rail 4 is controlled to slide in the opposite direction for a certain distance, and the mounting arm 5 is driven to slide to transport the cargo 9 into the cabin 6.

[0046] The control assembly also includes a third detection element 20 installed at the loading / unloading end of the compartment 6. The third detection element 20 is used to detect whether the cargo 9 has entered the compartment 6. Specifically, the third detection element 20 includes a through-beam photoelectric sensor installed on the lower part of the side wall of the compartment 6. The transmitter and receiver of the through-beam photoelectric sensor are respectively installed at opposite positions on the lower part of the side walls of the compartment 6. When no cargo 9 passes by, the beam of light (infrared light or laser) emitted by the transmitter of the through-beam photoelectric sensor is received by the receiver. When the cargo 9 passes by, the cargo 9 blocks the beam of light.

[0047] The third detection element 20 is connected to the controller signal. The controller is used to receive the detection signal from the third detection element 20 and control the sliding position of the mounting arm 5 according to the detection signal. Specifically, when the cargo 9 is in the lifting stage, the light beam is not obstructed. When the cargo 9 begins to enter the cabin 6, the light beam is obstructed. When the cargo 9 has completely entered the cabin 6, the light beam is not obstructed. Therefore, based on the signal change of whether the light beam is obstructed, it can be determined whether the cargo 9 has completely entered the cabin 6. When the cargo 9 has completely entered the cabin 6, the mounting arm 5 can be controlled to stop sliding.

[0048] In this embodiment, the goods 9 transported into the compartment 6 are positioned near the side wall of the compartment 6, just inside the compartment 6 but close to the opening. This facilitates subsequent organization and stacking of the goods 9 within the compartment 6, preventing them from being arbitrarily moved to any location within the compartment 6 and avoiding interference with staff placing goods 9. Furthermore, to facilitate the placement of goods 9 within the compartment 6, when space is sufficient, a conveyor belt can be installed. In this embodiment, the position where goods 9 are transported into the compartment 6 is designated as the loading end of the conveyor belt. The conveyor belt will then quickly remove goods 9 without affecting the transport of the next goods 9 into the compartment 6. When space is limited, even without a conveyor belt, staff can quickly remove and stack goods 9, ensuring that the operation does not interfere with the transport of the next goods 9 into the compartment 6.

[0049] In another embodiment of the present invention, the first driving member and the second driving member are arranged side by side, and a slide rod 21 is slidably connected on the mounting plate 15 between the first driving member and the second driving member. A baffle 14 is fixed at the lower end of the slide rod 21. The longitudinal section of the baffle 14 and the slide rod 21 is an inverted T-shape. When the slide rod 21 is located in the middle of the first driving member and the second driving member, the first driving member and the second driving member are both located above the baffle 14. When the slide plate slides toward the first driving member, the baffle 14 is no longer located below the second driving member. When the slide plate slides toward the second driving member, the baffle 14 is no longer located below the first driving member.

[0050] Specifically, a cylinder for driving the sliding rod 21 is installed on the mounting plate 15. By adjusting the position of the baffle 14, when the goods 9 are not being transported, the baffle 14 blocks both the first and second driving components from above to avoid affecting the stacking of the goods 9 in the compartment 6, and to a certain extent reduces interference between the gripper or hook 17 and the goods 9 in the compartment 6. When the goods 9 need to be transported, the sliding baffle 14 blocks the gripper when the hook 17 is used to avoid interference with the gripper when lifting the goods 9 upwards. When the gripper is used, the sliding baffle 14 blocks the hook 17 to avoid interference with the hook 17 when lifting the goods 9 upwards.

[0051] In this embodiment, in order to ensure that the camera 22 can capture images without being obstructed, the camera 22 is installed at the lower end of the baffle 14.

[0052] In another embodiment of the invention, a support assembly is also included. The support assembly includes a vertical support that is slidably connected to the outer wall of the vehicle compartment 6 in a vertical direction and a horizontal support 8 that is slidably connected to the bottom of the vertical support in a horizontal direction. The horizontal support 8 is used to provide support for the cargo 9 at the bottom of the cargo 9. A hydraulic cylinder for driving the vertical support to slide is provided on the outer wall of the vehicle compartment 6, and a hydraulic cylinder for driving the horizontal support 8 to slide is provided on the vertical support. Under normal circumstances, the horizontal support 8 is housed at the bottom of the outer wall of the vehicle compartment 6 and does not protrude from the vehicle.

[0053] The first driving component also includes a first load cell mounted on the output shaft of the winch 13. The first load cell is used to detect the weight borne by the output shaft of the winch 13. Specifically, the first load cell is a spoke-type load cell, rotatably connected to the output shaft of the winch 13 and fixed to the mounting plate 15. The second driving component also includes a second load cell mounted on the drive rod 12. The second load cell is used to detect the weight borne by the drive rod 12. The second load cell is a tension sensor mounted on the drive rod 12. In this solution, regardless of whether the hook 17 or the gripper is used, weight is measured during the lifting process. Weight measurement can be performed once the cargo 9 is off the ground. If the weight exceeds the limit, the cargo 9 is lowered directly, and the lifting operation stops.

[0054] After the hoisting stops, the staff can intervene by sliding the vertical support and the horizontal support 8 so that the horizontal support 8 is close to the ground and close to the cargo 9. Then, after the cargo 9 is hoisted off the ground again, the horizontal support 8 is driven to slide under the cargo 9 to support the cargo 9. Then, the cargo 9 is lifted upward and the vertical support is slid upward simultaneously. The heavy cargo 9 is hoisted by lifting and supporting it from above.
