[0019] The following will describe the specific embodiments of the present utility model in conjunction with the drawings. As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown: A lifting and conveying device for a new energy vehicle battery production line, including a bottom plate 1 as the foundation. A pair of symmetrically distributed scissor lifting mechanisms are arranged on the bottom plate 1.

The top end of the sixth support rod 13 is hinged to the second support rod 3, and its bottom end is hinged to the bottom of the side of the second translation plate 14.

[0021] Two groups of symmetrically distributed fixed pulley assemblies are arranged between the first translation plate 11 and the second translation plate 14. The fixed pulley assembly includes a first fixed pulley 15 and a second fixed pulley 16 arranged on the second translation plate 14, and a third fixed pulley 17 and a fourth fixed pulley 18 arranged on the first translation plate 11. The first fixed pulley 15 and the second fixed pulley 16 are respectively located on both side surfaces of the second translation plate 14, while the third fixed pulley 17 and the fourth fixed pulley 18 are located on the same side of the first translation plate 11. And the first fixed pulley 15 and the third fixed pulley 17 are at the same height, and the height of the second fixed pulley 16 is between the third fixed pulley 17 and the fourth fixed pulley 18.

[0022] A tensioning mechanism 19 is arranged at the bottom of the second translation plate 14. The tensioning mechanism 19 is connected to one end of a belt 20. The other end of the belt 20 passes through the fourth fixed pulley 18, the second fixed pulley 16, the third fixed pulley 17, and the first fixed pulley 15 in sequence, and then is connected to a winding and unwinding reel 21. The winding and unwinding reel 21 is rotatably supported on the bottom plate 1, and one end of the winding and unwinding reel 21 is connected to the output end of a gearbox 22, and a motor 23 is arranged at the input end of the gearbox 22.

[0023] A protection oil cylinder 24 is arranged between the first translation plate 11 and the second translation plate 14. The cylinder part of the protection oil cylinder 24 is fixedly connected to the first translation plate 11, and the output shaft of the protection oil cylinder 24 is fixedly connected to the second translation plate 14.

[0024] The tensioning mechanism 19 includes a tensioning shaft 25 movably connected to the second translation plate 14. One end of the tensioning shaft 25 is connected to the end of the belt 20 through a connector 26, and a retaining piece 27 is sleeved on the other end. The retaining piece 27 is fixed by an adjusting nut 28 and a backup tightening nut 29. A spring 30 is sleeved outside the tensioning shaft 25, and the spring 30 is located between the outer wall of the second translation plate 14 and the retaining piece 27.

[0025] A sensor bracket 31 is connected to the second translation plate 14, and a trigger sensor 32 is arranged on the sensor bracket 31. The trigger rod of the trigger sensor 32 is matched with the retaining piece 27.

[0026] Guide grooves 33 matching the rollers 5 are formed on the top end surface of the bottom plate 1 and the bottom end surface of the lifting plate 7.

[0027] The working process of the lifting and conveying device for a new energy vehicle battery production line according to the embodiment of the present utility model is as follows: Place the new energy vehicle battery to be lifted and conveyed on the lifting plate 7 of the device, and control the motor 23 to work through the control system to drive the scissor lifting mechanism to act, so as to achieve the purpose of driving the battery to lift;

[0028] In the initial state, the lifting plate 7 is in the low position. When it is necessary to let the lifting plate 7 drive the battery to rise to a certain height, start the motor 23, drive the winding and unwinding reel 21 to rotate through the gearbox 22. The rotation of the winding and unwinding reel 21 will cause the belt 20 to continuously wind on it. Since the belt 20 is wound on multiple fixed pulleys in the fixed pulley assembly, and these fixed pulleys are divided into two groups and are respectively connected to two translation plates that can move relative to each other, the first translation plate 11 and the second translation plate 14 will approach each other under the pulling action of the belt 20. When the first translation plate 11 and the second translation plate 14 approach each other, they will drive the first support rod 2 and the second support rod 3 to act through the third support rod 9 and the fourth support rod 10, the fifth support rod 12 and the sixth support rod 13. The action of the mutually hinged first support rod 2 and the second support rod 3, that is, the scissor lifting mechanism acts, to realize the lifting of the lifting plate 7;

[0029] When it is necessary to lower the lifting plate 7, only need to control the winding and unwinding reel 21 to rotate in the reverse direction;

[0030] During the above movement process, the rollers 5 at the ends of the first support rod 2 and the rollers 5 at the ends of the second support rod 3 will roll in the guide grooves 33 on the bottom end surface of the lifting plate 7 and the guide grooves 33 on the top end surface of the bottom plate 1 respectively, and the guide grooves 33 can limit the movement trajectories of the rollers 5;

[0031] Since a protection oil cylinder 24 is provided between the first translation plate 11 and the second translation plate 14, even if the belt 20 breaks and there is a risk of the lifting mechanism quickly retracting upon inspection, because the oil return speed of the protection oil cylinder 24 is constant, the first translation plate 11 and the second translation plate 14 will not quickly approach each other in a short time, that is, it plays a buffering role. This can effectively prevent the lifting plate 7 from quickly falling when the belt 20 breaks, protecting both the staff in the operating environment and the battery being transported;

[0032] After long-term use, the belt 20 will inevitably become loose, that is, the overall length of the belt 20 increases. To prevent the belt 20 from deforming and causing slipping and other situations, a tensioning mechanism 19 is also provided at the end of the belt 20. The spring 30 in the tensioning mechanism 19 always pushes the retaining piece 27 outward, so the tensioning shaft 25 fixedly connected to the retaining piece 27 always tightens the belt 20, thus keeping the belt 20 in a tensioned state; In the initial state, there is a certain gap between the retaining piece 27 and the trigger rod of the trigger sensor 32. After working for a period of time, the retaining piece 27 displaces relative to the second translation plate 14, that is, relative to the trigger sensor 32 supported on the second translation plate 14 through the sensor bracket 31. When the retaining piece 27 touches the trigger rod, the trigger sensor 32 sends a signal to the control system, and the control system issues a warning message to remind the staff that the belt 20 has reached a certain degree of deformation, and the staff can replace or process it in time.
