Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to a vehicle-mounted lifting platform for an unmanned transport vehicle. Background Technology

[0002] With the development of industrial automation and intelligent logistics, unmanned transport vehicles have been widely used in logistics transportation, material handling in production workshops and other fields.

[0003] However, existing unmanned transport vehicles have limitations when dealing with loading and unloading positions at different heights. Some goods need to be loaded and unloaded at higher or lower positions, and ordinary transport vehicles cannot easily adjust their height to meet these needs. This may lead to low loading and unloading efficiency, and may even require additional auxiliary equipment to complete the loading and unloading work, increasing costs and operational complexity. Therefore, we propose an onboard lifting platform for unmanned transport vehicles to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an unmanned transport vehicle-mounted lifting platform, which can control the lifting cylinder and electric push rod through the controller, and can achieve the purpose of lifting and locking the carrying platform.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an unmanned transport vehicle-mounted lifting platform, including a frame, a carrying platform above the frame, two lifting mechanisms between the frame and the carrying platform, a connecting frame fixedly installed at the bottom of the frame, a reinforcing rod fixedly installed at the top of the connecting frame, and the top end of the reinforcing rod fixedly installed on the frame, movable wheels on the front and rear sides of the frame, and a pushing mechanism connected to the lifting mechanism on the reinforcing rod, the lifting mechanism including a lower connecting seat, an upper drive seat, a rotating shaft, and a scissor fork, the lower connecting seat fixedly installed on the top of the frame, the upper drive seat fixedly installed on the carrying platform, a rotating shaft rotatably installed between the two lower connecting seats, and the two ends of the scissor fork rotatably sleeved on the two rotating shafts respectively.

[0006] By adopting the above technical solution, the controller can control the lifting cylinder and electric push rod, thereby achieving the purpose of raising, lowering and locking the load-bearing platform.

[0007] The present invention is further configured such that the lifting mechanism includes an upper drive seat two, a mounting plate, a U-shaped sliding seat, a rotating shaft two, and a scissor fork two. The upper drive seat two is fixedly mounted on the bearing platform, the mounting plate is fixedly mounted on the frame, the U-shaped sliding seat is slidably mounted on the top of the mounting plate, and a rotating shaft two is rotatably mounted between the two upper drive seats two and the two U-shaped sliding seats, and the two ends of the scissor fork two are respectively rotatably mounted on the rotating shaft two.

[0008] By adopting the above technical solution and by setting up scissor forks one and two, the purpose of lifting and lowering the carrying platform can be achieved.

[0009] A further feature of this invention is that a connecting shaft is rotatably mounted between two adjacent scissor forks, with each end of the connecting shaft passing through a corresponding scissor fork, and both scissor forks 1 and 2 being rotatably connected to the connecting shaft.

[0010] By adopting the above technical solution and by setting a connecting shaft, the scissor fork one and scissor fork two can be rotatably connected.

[0011] A further feature of this invention is that the pushing mechanism includes a lifting cylinder, a rotating sleeve, and a rotating seat. The rotating seat is fixedly installed on the bottom of the lifting cylinder and rotatably installed on a reinforcing rod. A rotating sleeve is fixedly installed on the output shaft of the lifting cylinder and is rotatably mounted on a corresponding rotating shaft.

[0012] By adopting the above technical solution and by setting up a pushing mechanism, the extension of the lifting cylinder can drive the rotating shaft two to move.

[0013] A further feature of this invention is that two guide seats are fixedly installed on the top of the mounting plate, and the U-shaped sliding seat is slidably connected to the corresponding guide seat. Limiting grooves are provided on the sides of the two corresponding guide seats that are close to each other. Limiting seats are fixedly installed on both sides of the U-shaped sliding seat, and the limiting seats are slidably connected to the corresponding limiting grooves.

[0014] By adopting the above technical solution and setting a limiting seat and a limiting groove, the U-shaped sliding seat can achieve stable movement.

[0015] A further feature of this invention is that a reinforcing plate is fixed between the two guide seats, a locking seat is fixedly and rotatably sleeved on the rotating shaft, and the locking seat is slidably connected to the reinforcing plate. The top of the reinforcing plate is provided with multiple locking grooves, a horizontal plate is fixedly installed on one side of the locking seat, and a locking mechanism is provided on the horizontal plate, and the locking mechanism is adapted to the locking groove.

[0016] By adopting the above technical solution, the locking seat can be guided by the reinforcing plate, thereby enabling the locking seat to slide stably on the reinforcing plate.

[0017] A further feature of this invention is that the locking mechanism includes an electric push rod and a locking pin. The electric push rod is fixedly mounted on the horizontal plate, and a locking pin is fixedly mounted on the output shaft of the electric push rod. The locking pin is adapted to a corresponding locking groove. A controller is mounted on the frame, and both the electric push rod and the lifting cylinder are connected to the controller.

[0018] By adopting the above technical solution, the controller can activate the electric push rod, which can drive the locking pin to move downwards. The locking pin can then be inserted into the corresponding locking groove, thereby achieving the purpose of locking the carrying platform.

[0019] The beneficial effects of the utility model are:

[0020] (1) When the platform needs to lift the goods, the lifting cylinder is started by the controller. The lifting cylinder rotates the corresponding rotating shaft one through the rotating sleeve. The rotating shaft one moves through the drive seat two, so that the scissor fork one and the scissor fork two rotate. The drive seat one and the drive seat two can drive the platform to move upward synchronously. At the same time, the U-shaped sliding seat and the rotating shaft two can move. The rotating shaft two can drive the locking seat to slide on the reinforcement plate.

[0021] (2) When the carrying platform is raised to the specified height, the position of the locking pin corresponds to the position of the corresponding locking groove. The controller can start the electric push rod, which can drive the locking pin to move downward. The locking pin can be inserted into the corresponding locking groove to achieve the purpose of locking the carrying platform. Attached Figure Description
