Detailed Embodiments

[0017] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0018] As Figures 1 to 3 shown, where Figure 1It is a schematic diagram of the overall structure of a semi-automatic lifting vehicle, Figure 2 It is a schematic diagram of the structure of the X-shaped lifting rod 104, Figure 3 It is a rear view of the placement plate 108. The present utility model provides a semi-automatic lifting vehicle, which includes a frame 101 and an auxiliary mechanism. A moving wheel 102 is installed at the bottom of the frame 101, and a control box 103 is installed at the rear side. The auxiliary mechanism includes an X-shaped lifting rod 104, a reducer 105, an action screw 106, a threaded seat 107, a placement plate 108, a support frame 109, a roller device and a pushing device.

Through the foregoing solution, it is possible to adjust the height according to the picking situation when picking up parts after transporting automotive parts, reduce the labor intensity of workers, and be more conducive to production use. It can be understood that the foregoing solution can solve the problem that when workers pick up the uppermost and lowermost products, the traditional trailer cannot adjust the height, resulting in workers bending over for a long time, increasing the labor intensity of production and being prone to causing harm to the human body.

[0019] In this embodiment, a moving wheel 102 is installed at the bottom of the frame 101, and a control box 103 is installed at the rear side. The moving wheel 102 facilitates the movement of the vehicle, and a socket and an external movable plug-in cable are provided on the right side of the control box 103, which is convenient for work control.

[0020] Among them, the X-shaped lifting rod 104 is arranged between the frame 101 and the placing plate 108. The speed reducer 105 is fixed on the frame 101 and is electrically connected to the control box 103. The action screw rod 106 is connected to the output shaft of the speed reducer 105 through a T-shaped pin shaft. The threaded seat 107 is arranged on the connecting rod of the X-shaped lifting rod 104 and is in threaded cooperation with the action screw rod 106. The placing plate 108 is arranged at the top of the X-shaped lifting rod 104. The support frame 109 is fixedly connected to the frame 101, is rotatably connected to the action screw rod 106, and is located on one side of the frame 101 close to the action screw rod 106. The roller device is arranged on the upper and lower sides of the X-shaped lifting rod 104. The pushing device is arranged at the rear side of the frame 101. At the upper and lower mounting ends on the front side of the X-shaped lifting rod 104, the two lower mounting ends are directly mounted on the frame 101 through T-shaped pin shafts. A nut is mounted on the outer threaded end of the T-shaped pin shaft away from the limit disc for limiting to prevent crosstalk and falling off. The upper mounting end on the front side of the X-shaped lifting rod 104 is mounted in the mounting cavity at the bottom of the placing plate 108 through a T-shaped pin shaft, and the ends are respectively fixed. A nut is mounted on the outer threaded end of the T-shaped pin shaft away from the limit disc for limiting to prevent crosstalk and falling off. The speed reducer 105 is fixed on the frame 101 through bolts and is electrically connected to the control box 103 through cables. When the threaded seat 107 is installed, it is directly sleeved on the connecting rod at the bottom rear side of the X-shaped lifting rod 104 and can slide after installation, which is beneficial for self-position adjustment. The action screw rod 106 can be in rotational cooperation with the threaded seat 107. The support frame 109 is fixed on the frame 101 through bolts. The front mounting end of the action screw rod 106 is mounted on the support frame 109 through a rotating bearing. After the rear mounting end is inserted into the mounting hole on the output shaft of the speed reducer 105, a T-shaped pin shaft is inserted, and a nut is mounted on the pin shaft for limiting to facilitate stable transmission. The roller device is used for guiding and limiting the movement of the X-shaped lifting rod 104. The pushing device facilitates the movement of the trolley.

[0021] Secondly, the fixed side of the X-shaped lifting rod 104 is provided with a limit sleeve 110. When the limit sleeve 110 is mounted on the upper sides of the two front ends of the X-shaped lifting rod 104, it will abut against the side wall of the guiding groove of the placing plate 108.

[0022] Then, the upper rollers 111 are rotatably arranged on both sides of the top of the X-shaped lifting rod 104 and can slide in the limit sliding grooves on the placing plate 108; the lower rollers 112 are arranged on both sides of the bottom of the X-shaped lifting rod 104 and can roll on the frame 101. The end of the mounting shaft of the upper roller 111 is installed on the X-shaped lifting rod 104 through a rotating bearing and can slide in the limit sliding grooves on the placing plate 108 at the same time to ensure the stable position of the X-shaped lifting rod 104. Step holes are arranged on both sides of the lower roller 112, and bearings are respectively embedded. When the connecting rod fixed by the threaded seat 107 is arranged on the X-shaped lifting rod 104, it cooperates with the connecting rod. The cross section of the connecting rod is T-shaped, and a nut limit is arranged on the side away from the limit disc to avoid crosstalk. At the same time, the connecting rod limiting plate and the nut do not abut against the side wall of the frame 101 to ensure stable sliding. Wear-resistant layers are respectively arranged on the outer surfaces of the upper roller 111 and the lower roller 112, which is convenient for extending the service life, prolonging the replacement time and reducing the use cost.

[0023] Furthermore, the positioning rods 113 are welded on both sides of the tail of the frame 101; the push rods 114 are welded on the positioning rods 113. The two positioning rods 113 are welded on the frame 101, and the push rods 114 are welded on the positioning rods 113.

[0024] Finally, the reducer 105 is powered by plugging in an external movable wear-resistant cable. The function of this power supply method is that the drive motor of the reducer 105 is not powered by a battery but directly plugged in and powered by a cable and a plug, avoiding setting a battery box on the frame 101, greatly reducing the weight of the trolley and facilitating the workers to push. The plug of the connecting cable of the reducer 105 can be directly plugged into the socket on the right side of the control box 103.

[0025] When using the present utility model to achieve picking up parts after transporting automotive parts, the height can be adjusted according to the picking situation, reducing the labor intensity of workers and being more conducive to production use. First, when transporting automotive parts or corresponding materials, the material boxes can be directly stacked on the placement plate 108. Then, through the cooperation of the pushing device and the moving wheels 102, the frame 101 and the placement plate 108 can be moved, thereby realizing the movement of the trolley for material transportation. When picking up materials, the forward and reverse rotation of the speed reducer 105 can be controlled by pressing the buttons on the control box 103. After the speed reducer 105 operates, it can drive the action screw 106 to rotate in cooperation with the threaded seat 107, thereby driving the X-shaped lifting rod 104 to deform after operating. The roller device performs rolling guidance and limitation to realize the height adjustment of the placement plate 108. When the placement plate 108 descends to the lowest point, at this time, both sides of the placement plate 108 can abut against the top end face of the frame 101 for limitation, and the U-shaped groove at the bottom of the placement plate 108 can avoid the speed reducer 105, thus solving the problem that when workers pick up the products at the top and the bottom, due to the traditional trailer being unable to adjust the height, workers have to bend down for a long time, increasing the labor intensity of production and being prone to causing harm to the human body. Furthermore, when picking up parts after transporting automotive parts, the height can be adjusted according to the picking situation, reducing the labor intensity of workers and being more conducive to production use.
