Detailed Description
The invention will be further described with reference to examples in the drawings to which:
as shown in figures 1-2, the invention mainly comprises a main beam 1, a swing arm 3, a suspension arm 5, a main beam 7 and a support seat 8.
The swing arm support 2 is fixed at the center of the main beam 1, and the swing arm support 2 is connected with the center of the swing arm 3 in a rotating mode through a pin shaft. The main beam 1 is connected with two suspension arms 5 in a sliding way, and the two suspension arms 5 are symmetrically distributed at the left side and the right side of the swing arm support 2.
Two ends of the swing arm 3 are respectively and rotatably connected with a follow-up connecting rod 4, and the connecting rods 4 at two ends of the swing arm 3 are respectively and rotatably connected with two suspension arms 5. The lower end of the suspension arm 5 is welded with a main beam 7, and the welding point of the suspension arm 5 and the main beam 7 is positioned on one side of the central position of the main beam 7. Two ends of the main beam 7 are respectively connected with a supporting seat 8, and the upper end face of the supporting seat 8 is detachably connected with a supporting block 9 through a connecting piece. When the vehicle body is conveyed, the vehicle body is supported by the four supporting blocks 9 together.
In order to facilitate the suspension arm 5 to slide on the main beam 1, a travelling wheel 6 is arranged in the suspension arm 5, and the travelling wheel 6 is connected to the main beam 1 in a rolling manner.
The two ends of the main beam 1 are respectively and rotatably connected with the middle part of an operating rod 16, one end of the operating rod 16 extends out towards the main beam 1 and is rotatably connected with one end of a driving connecting rod 17, and the other ends of the driving connecting rods 17 at the two ends of the main beam 1 are respectively and rotatably connected with the two ends of the swing arm 3.
One end of the operating rod 16 extends out of the main beam 1 and is connected with a handle 18, and the operating rod 16 can be conveniently operated through the handle 18.
In order to prevent the vehicle body from falling off the lifting appliance, the two ends of the main beam 1 are respectively connected with an auxiliary hanging bracket 13, and the lower end of the auxiliary hanging bracket 13 is connected with an auxiliary cross beam 14. Protective belts 15 are respectively arranged on two sides of the main beam 1, and two ends of each protective belt 15 are respectively connected to the auxiliary cross beams 14 at two ends of the main beam 1.
The upper end of the main beam 1 is provided with a hanging beam 10, the two ends of the hanging beam 10 are respectively provided with an upper hanging bracket 11, the upper hanging bracket 11 is rotatably connected with a lower hanging bracket 12 through a pin shaft, and the lower hanging bracket 12 is welded on the main beam 1.
The working principle of the invention is as follows: when the vehicle body reaches the station, a lifting hoist descending button is pressed, the lifting hoist is connected with the hanging beam of the invention, and the hanging beam drives the main beam to descend. When the supporting block of the main beam reaches below the window of the vehicle body, the supporting block supports the upper edge of the window, the lifting button of the lifting hoist is pressed, and the whole lifting appliance is driven by the lifting hoist to move to the next station. When the automobile arrives at the conveying station, the lifting block descending button is pressed to enable the supporting block to leave the upper edge of the automobile window. Then, an operator can operate the handle on one side (namely, press the handle downwards), the operating rod drives the driving connecting rod to move outwards, the driving connecting rod pulls the swing arm to rotate, and when the swing arm rotates, the follow-up connecting rod drives the suspension arm to move along the main beam, so that the supporting block of the suspension arm is separated from the vehicle body, namely, the vehicle body is in a free state.
