[0027] refer to Figure 1 As shown, an embodiment of the present invention provides a foldable lifting and transporting device, including a vehicle body 11, a load-bearing bracket and a lifting trolley 12.

[0028] The vehicle body 11 is used to provide power and drive the device to work and travel.

[0029] The supporting bracket includes a first bracket 13 , a second bracket 14 and a crossbeam 15 .

[0030] The first bracket 13 includes a first support seat 131 and a first lifting cylinder 132. The first support seat 131 is a plate-like structure and is disposed at the front end of the vehicle body 11. The first support seat 131 is rotatably connected to the upper side of the front end of the vehicle body 11. A receiving chamber 111 is provided at the top of the vehicle body 11. A first driver 133 is provided within the receiving chamber 111. One end of the first driver 133 is hinged to the first support seat 131, and the other end of the first driver 133 is hinged to the vehicle body 11. The first driver 133 is used to drive the first support seat 131 to rotate to a first state in which it is vertical and located at the front end of the vehicle body 11, and to drive the first support seat 131 to rotate to a second state in which it is supported at the top of the vehicle body 11. The first driver 133 is a hydraulic cylinder.

[0031] The first lifting cylinder 132 is mounted on the first support base 131. The upper end of the first lifting cylinder 132 is hinged to one end of the crossbeam 15. A second actuator 134 is provided near the hinged connection between the first lifting cylinder 132 and the crossbeam 15. One end of the second actuator 134 is hinged to the first lifting cylinder 132, and the other end of the second actuator 134 is hinged to the crossbeam 15. The second actuator 134 can drive the crossbeam 15 to unfold, aligning it with the first lifting rod. The second actuator 134 can also drive the crossbeam 15 to fold, aligning it with the first lifting cylinder 132. The crossbeam 15 can be folded or unfolded as needed. Both the first lifting cylinder 132 and the second actuator 134 can be hydraulic cylinders. The lower end of the first support base 131 can be provided with rollers 144 to provide support without affecting movement.

[0032] The second bracket 14 includes a second support base 141 and a second lifting cylinder 142. The lower end of the second lifting cylinder 142 is detachably connected to the upper end of the second support base 141, and the upper end of the second lifting cylinder 142 is hinged to the end of the beam 15 away from the first lifting cylinder 132.

[0033] A third actuator 143 is provided near the hinged connection between the second lift cylinder 142 and the crossbeam 15. One end of the third actuator 143 is hinged to the second lift cylinder 142, and the other end is hinged to the crossbeam 15. The third actuator 143 can drive the second lift cylinder 142 to expand, placing the second lift cylinder 142 and the crossbeam 15 perpendicular to each other. The third actuator 143 can also drive the second lift cylinder 142 to fold, placing the second lift cylinder 142 parallel to the crossbeam 15. The third actuator 143 can be folded and expanded as needed. Both the second lift cylinder 142 and the third actuator 143 can be hydraulic cylinders.

[0034] At least three rollers 144 are provided at the bottom of the second support seat 141, which can better ensure the stability of the second support seat 141. A plurality of reinforcing rods 145 are provided around the circumference of the second lifting cylinder 142. One end of the reinforcing rod 145 is hinged to the second lifting cylinder 142, and the other end is detachably connected to the second support seat 141. The plurality of reinforcing rods 145 form a conical structure. The setting of the reinforcing rods 145 can better ensure the stability of the second lifting cylinder 142.

[0035] The crossbeam 15 is a telescopic structure that can be extended or shortened as needed. A travel groove is provided on the crossbeam 15, and the wheels 122 of the lifting trolley 12 are located in the travel groove. The lifting trolley 12 can reciprocate along the length direction of the crossbeam 15 under power drive. The body 121 of the lifting trolley 12 is connected to the wheels 122 by a spring 123 (refer to FIG. Figure 2 As shown), this ensures that the wheel 122 of the lifting trolley 12 is always in contact with the travel groove to ensure sufficient friction and also plays a shock-absorbing role.

[0036] A camera 16 is installed on the end of the crossbeam 15, away from the vehicle body 11. This camera monitors the surrounding environment and also locates the device when it reaches its operating position. Pressure sensors are installed on the sides of the crossbeam 15 to monitor its operation and prevent accidents caused by heavy objects being dropped. Distance sensors are also installed around the vehicle body 11 to help the device avoid obstacles and accurately reach its designated location during travel.

[0037] A hook or storage slot is provided on one side of the vehicle body 11, which is convenient for hanging or storing some auxiliary supplies.

[0038] The vehicle body 11 is also provided with an intelligent monitoring and control mechanism, including a motion control system and a movement control system. An operating panel connected to the motion control system and the movement control system is arranged on one side of the vehicle body 11. The motion control system is used to control the movement of each hydraulic cylinder to expand or fold the device. It can also control the movement of the lifting trolley 12 and the raising and lowering of the wire rope to lift or transport items. The movement control system is used to control the direction and speed of the driving wheels of the vehicle body 11, thereby completing the movement or steering of the device. The movement control system has two movement conditions: one is the movement of the vehicle body 11 with a change in angle, and the other is the translational movement of the vehicle body 11 with a constant angle. The first movement condition is used for the transportation and handling of the entire device, and the second movement condition is used for the change of the overall position of the device after formation. The intelligent monitoring and control mechanism also includes a Bluetooth module and controller connected to each hydraulic cylinder and drive motor to achieve remote wireless control and data acquisition of the device.

[0039] When using this device, the supporting bracket needs to be unfolded (refer to Figure 1 Specifically, the first driver 133 drives the first support base 131 to rotate to a vertical position, and then the first lifting cylinder 132 extends to raise the crossbeam 15. The second driver 134 then drives the crossbeam 15 to expand until it is perpendicular to the first lifting cylinder 132. At this point, the crossbeam 15 is horizontal. The third driver 143 then drives the second lifting cylinder 142 to expand, so that the second lifting cylinder 142 is perpendicular to the crossbeam 15. The second lifting cylinder 142 then expands, connecting the lower end of the second lifting cylinder 142 to the upper end of the second support base 141. At the same time, the reinforcing rod 145 is fixed, and the device is moved to the desired lifting position. At this time, the lifting trolley 12 can lift the object, and after lifting, the object can be transported to the designated location. Of course, if the object to be lifted is light, the second lifting cylinder 142 does not need to be expanded.

[0040] When the device is not in use, the support bracket can be folded up (refer to Figure 2 When folding is required, the crossbeam 15 is first retracted and shortened, and then the second lifting cylinder 142 is disassembled from the second support base 141. The second support base 141 can be stowed and hung on one side of the vehicle body 11. The second lifting cylinder 142 is then retracted and shortened. Then, the third driver 143 drives the second lifting cylinder 142 to fold up, so that the second lifting cylinder 142 and the crossbeam 15 are parallel to each other. Then, the second driver 134 drives the crossbeam 15 to fold up, so that the crossbeam 15 and the first lifting cylinder 132 are parallel to each other. The first lifting cylinder 132 is further retracted and shortened, and the first driver 133 drives the first support base 131 to rotate to a horizontal position and be located on the top of the vehicle body 11, thereby completing the folding of the device, making the device smaller in size and convenient for entering and exiting narrow places or storing in corresponding places.

[0041] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
