Description

Technical Field

[0001] The utility model relates to the technical field of transportation and loading, in particular to a lifting support structure. Background Art

[0002] Automatic loading equipment can automatically load goods into the cargo box of a truck to replace manual loading, thereby reducing the labor intensity and labor costs of manual handling, such as the cargo loading and conveying device and loading equipment in CN117775786A. After the goods are conveyed to the first conveying assembly, the telescopic mechanism drives the conveying assembly and the goods to descend. Since the telescopic mechanism adopts a cylinder and a fork arm connecting rod assembly, as the height of the goods decreases, the angle between the force direction of the cylinder and the vertical direction will become larger and larger. When it descends to a certain height, if the goods are heavy, the force of the cylinder is insufficient to support the weight of the goods and the first conveying assembly, which may cause the goods to fall rapidly and not smoothly, or even cause collision and damage to the goods.

The movable base plate 2 can move in the front and rear directions relative to the feeding frame 12. The flipping module includes a flipping frame, a telescopic mechanism 4 and a conveying assembly 5. The flipping frame is rotatably connected to the movable base plate 2. The flipping frame includes a first support 31 and a second support 32. The second support 32 is arranged at the front side of the first support 31 and is arranged at an angle to the first support 31. The telescopic mechanism 4 includes a fork arm assembly 41 and a telescopic cylinder 42. The conveying assembly 5 includes a conveying pallet 51. The fork arm assembly 41 is connected between the first support 31 and the conveying pallet 51. The cylinder body of the telescopic cylinder 42 is connected to the first support 31. The output shaft of the telescopic cylinder 42 is transmission connected to the fork arm assembly 41.

The flipping drive mechanism 33 is arranged on the movable base plate 2. The flipping drive mechanism 33 is transmission connected to the flipping frame. The flipping drive mechanism 33 can drive the flipping frame to rotate back and forth.

[0034] The support mechanism 6 is arranged on the left side and / or right side of the telescopic flipping device. The support mechanism 6 includes a support cylinder 61 and a support member 62.

[0035] A support mechanism 6 is provided on the frame 1. When the goods 9 are transported to the conveying assembly 5, the first supporting portion 31 is at the rear lower side of the second supporting portion 32. The first supporting portion 31 is basically arranged horizontally. The conveying assembly 5 is arranged horizontally and is located on the upper side of the first supporting portion 31. Then the telescopic cylinder 42 and the fork arm assembly 41 of the telescopic mechanism 4 drive the conveying assembly 5 and the goods 9 to move downward. At this time, the support member 62 of the support mechanism 6 supports the lower side of the conveying tray 51. Figure 3 and Figure 4 , the supporting cylinder 61 and the supporting member 62 also move downward synchronously. When the force of the telescopic cylinder 42 is insufficient to support the cargo 9 and the cargo 9 tends to fall rapidly, the supporting member 62 and the supporting cylinder 61 can support the conveying assembly 5 and the cargo 9 to keep descending slowly, so that the cargo 9 can descend more smoothly; the supporting mechanism 6 is arranged on the frame 1, does not occupy the structural space of the telescopic flipping device, and has little effect on the subsequent action process of the telescopic flipping device.

[0036] The frame 1 is provided with a first feed drive mechanism, which is in transmission connection with the feed frame 12 and can drive the feed frame 12 to move forward and backward. The first feed drive mechanism can adopt a rack and pinion drive mechanism.

For details of the frame 1, the feed frame 12, the telescopic and tilting device, and the loading process, please refer to CN117775786A.

[0037] In some specific embodiments, there are two support mechanisms 6, which are respectively provided on the left and right sides of the conveyor tray 51. The two support mechanisms 6 respectively support the left and right sides of the conveyor tray 51, so that the conveyor tray 51 and the goods 9 are supported on both sides during descent, making the descent smoother.

[0038] In some specific embodiments, referring to Figure 2 The support mechanism 6 also includes a support guide rod 63, which extends in the up and down directions. The support guide rod 63 is fixedly connected to the frame 1, and the support member 62 is slidably connected to the support guide rod 63.

[0039] The support member 62 is slidably connected to the support guide rod 63, and the support guide rod 63 can provide guidance for the support member 62 in the up and down directions to prevent the support member 62 and the support cylinder 61 from lateral deviation during the up and down movement.

[0040] Further, support guide rods 63 are provided on both the front side and the rear side of the support oil cylinder 61. The lower end of the support guide rod 63 is fixedly connected to the frame 1. A fixed cross bar 11 is also provided on the frame 1. The fixed cross bar 11 is disposed above the support guide rod 63, and the upper end of the support guide rod 63 is fixedly connected to the fixed cross bar 11.

[0041] Support guide rods 63 are provided on both the front side and the rear side of the support oil cylinder 61. The two support guide rods 63 can improve the movement stability of the support member 62. The lower side and the upper side of the support guide rod 63 are respectively fixed to the frame 1 and the fixed cross bar 11, which can improve the strength of the support guide rod 63.

[0042] In some specific embodiments, the width of the conveying tray 51 in the left - right direction is greater than the widths of the first supporting portion 31 and the movable bottom plate 2 in the left - right direction. The support member 62 is arranged to match the portion of the conveying tray 51 that protrudes beyond the first supporting portion 31 in the left - right direction. The support member 62 is located outside the fork arm assembly 41 in the left - right direction.

[0043] When the conveying tray 51 and the goods 9 descend, the support member 62 supports the portion of the conveying tray 51 that protrudes beyond the first supporting portion 31 and the movable bottom plate 2 in the left - right direction. The support member 62 does not interfere with the first supporting portion 31, the movable bottom plate 2, and the fork arm assembly 41. In this way, after descending in place, the telescopic and flipping device can move forward for loading, and after the loading is completed, the telescopic and flipping device can directly move backward. The support mechanism 6 does not need to avoid the forward and backward movement of the telescopic and flipping device, and the structure of the support mechanism 6 is relatively simple.

[0044] In some specific embodiments, the telescopic oil cylinder 42 is connected with a first throttle valve for adjusting and controlling the speed of the telescopic oil cylinder 42. The support oil cylinder 61 is connected with a second throttle valve for adjusting and controlling the speed of the support oil cylinder 61.

The support oil cylinder 61 can change the flow rate in the oil circuit by adjusting the second throttle valve to adjust the movement speed, so that the movement speeds of the telescopic oil cylinder 42 and the support oil cylinder 61 can be adjusted to cooperate with each other to achieve the effect of the goods 9 descending smoothly.

[0046] In some specific embodiments, referring to Figure 2 , a position detection device 7 is fixed on the frame 1.

The position detection device 7 is used to detect whether the support member 62 moves to the upper side, and the position detection device 7 is signal - connected to the telescopic oil cylinder 42.

[0047] Only when the position detection device 7 detects that the support member 62 is in the upper position can the telescopic oil cylinder 42 be controlled to descend, which can ensure that the goods 9 are supported by the support member 62 when descending, thereby improving the stability during descent. The position detection device 7 can adopt a proximity switch. A displacement sensor can be installed on the fork arm assembly 41 to detect the lifting height of the telescopic oil cylinder 42 and the conveying assembly 5, and cooperate with the height of the conveyed goods and the detection signal of the position detection device 7 to ensure the normal operation of the equipment.

[0048] In some specific embodiments, a position-in-place detection device 8 is fixed on the frame 1. The position-in-place detection device 8 is located at the front end on the upper side of the conveying assembly 5. The position-in-place detection device 8 is used to detect whether there are goods 9 conveyed onto the conveying assembly 5. Both the telescopic oil cylinder 42 and the support oil cylinder 61 are signal-connected to the position-in-place detection device 8.

[0049] When the goods 9 are conveyed onto the conveying assembly 5, the position-in-place detection device 8 detects the goods 9 and triggers a signal, and then the telescopic oil cylinder 42 and the support oil cylinder 61 start to descend together, improving the synchronization of the descending actions of the telescopic oil cylinder 42 and the support oil cylinder 61. The position-in-place detection device 8 can adopt a proximity switch or a photoelectric sensor.
