Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, specifically relating to an on-board alignment and locking system. Background Technology

[0002] After the vehicle carrying goods arrives at the designated location, the intelligent lifting platform transfers the goods. However, there may be a slight deviation between the placement of the goods on the vehicle and the alignment with the intelligent equipment. Therefore, an alignment device is needed for adjustment. After the goods are in place, the alignment operation is performed. This process requires additional adjustment equipment. If the adjustment is done manually, the level of intelligence is low and the safety is poor. If the adjustment is automated, corresponding actuators and position detection sensors are also required. The adjustment mechanism requires high precision, which also results in long alignment time, low efficiency, and high cost.

[0003] In addition, during alignment, the goods are locked. Existing locking devices are usually screw-type, which require the smart device to be aligned with the locking point of the goods. Alignment is difficult and requires a high degree of alignment, resulting in long time and low efficiency. Moreover, the locking device requires manual operation and cannot be fully intelligent.

[0036] An even number of alignment units 3 are provided and are located on opposite sides of the first direction of the placement area. In this embodiment, four alignment units 3 are used and are respectively located at the four corners of the platform 1. They can operate individually or in groups to adjust and clamp the goods in the left and right directions.

[0037] The alignment unit 3 includes a push rod, an alignment drive component that drives the push rod to move closer to or further away from the placement area, an alignment power source that provides power to the alignment drive component, a displacement sensor, and a pressure sensor. In this embodiment: the push rod and the alignment drive component are alignment hydraulic cylinders 30, the push rod is the piston rod 300 of the alignment hydraulic cylinder 30, the alignment power source is a hydraulic pump, and the hydraulic pump provides hydraulic oil to the alignment hydraulic cylinder 30; the displacement sensor is installed in the working pipeline of the alignment hydraulic cylinder 30 to monitor the extension length of the piston rod 300 of the alignment hydraulic cylinder 30, and the pressure sensor is installed in the working pipeline of the alignment hydraulic cylinder 30 to monitor the pressure of the alignment hydraulic cylinder 30.

[0038] The locking unit 4 is also provided in an even number and is located on opposite sides in the second direction of the placement area. In this embodiment, four alignment units 3 are used and are respectively located at the four corners of the platform 1. They can operate individually or in groups to form a four-point locking of the goods. The goods can be adjusted back and forth when clamped.

[0039] like Figure 3 As shown: The locking unit includes a locking arm 40, a locking drive component that drives the locking arm, a locking power source that provides power to the locking drive component, an angle sensor 42, and a pressure sensor 43. One end of the locking arm 40 is connected to the platform 1 via a locking arm support 44, and the locking arm 40 and the locking arm support 44 are rotatably connected via a rotating shaft 45. The other end of the locking arm 40 forms a hook 400, and a buffer pad 46 is provided on the end face of the hook 400. The buffer pad 46 can both protect the locked goods and fill the gap between the locking arm 40 and the goods. The locking drive component is a locking hydraulic cylinder 41. The cylinder body of the locking hydraulic cylinder 41 is connected to the platform 1 via a cylinder support 47, and the locking hydraulic cylinder 41 and the cylinder support 47 are rotatably connected. The piston rod of the locking hydraulic cylinder 41 is connected to the locking arm 40.

There are four position sensors located at the four corners of the placement area on platform 1 to detect the position of goods on platform 1. The position sensors are connected to the micro-controller, which is connected to the alignment hydraulic cylinder 30, the locking hydraulic cylinder 41, and the hydraulic pump to control their operation.

[0042] In this embodiment: the first direction is the left and right direction of the platform, and the second direction is the front and back direction of the platform. Of course, the alignment unit 3 and the locking unit 4 can also be interchanged.

[0043] The working process of this embodiment is described in detail below:

[0044] The goods are placed on the slide plate 2. The position sensor detects the position of the goods on the platform 1 and sends the position signal to the microcontroller. The microcontroller controls the piston rod 300 of the alignment unit 3 to extend. The piston rod 300 pushes the goods, so that the goods adjust their position in the left and right directions of the platform along with the slide plate 2. The four piston rods 300 adjust by extending different lengths. At the same time, the microcontroller controls the locking arm 40 of the locking unit 4 to rotate. During the rotation, the goods are pushed to adjust their position in the front and back directions of the platform along with the slide plate 2. After the position adjustment is completed, the hook 400 of the locking arm 40 hooks the goods and completes the fixation.
