DETAILED DESCRIPTION

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] As shown in Fig. 1-2, a painting lifting platform comprises a column 1, a lifting mechanism 2, a lower platform 3, an upper platform 4, a guardrail 5 and a traction mechanism 6. The lower platform 3 is escalably mounted on one side of the column 1 through the lifting mechanism 2, and the upper platform 4 is mounted on the lower platform 3 and can slide relative to the lower platform 3. The traction mechanism 6 is installed between the upper platform 4 and the lower platform 3, and is used to guide the upper platform 4 to move along the lower platform 3 toward the side close to the column 1.

[0026] like Figure 1-3 As shown, two columns 1 are respectively fixed on one side of the production operation channel, and a crossbeam 11 is fixed between the tops of the two columns 1, thereby improving the stability of the columns 1. Specifically, the columns 1 and the crossbeam 11 are welded from steel plates, the cross section of the column 1 is U-shaped, and an upper connecting plate 12 and a lower connecting plate 13 are welded to the upper and lower ends of the column 1, respectively. The upper connecting plate 12 is fixedly connected to the crossbeam 11 by bolts, and the lower connecting plate 13 is fixed to the ground by expansion bolts.

[0027] The lifting mechanism 2 includes a lifting motor 21, a lead screw 22, a connecting seat 23, a guide rod 24 and a chain 25. The two ends of the lead screw 22 are connected to the upper connecting plate 12 and the lower connecting plate 13 through bearings, so that the lead screw 22 is vertically installed on the inner side of the U-shaped structure of the column 1. The lifting motor 22 is installed on the top of any column 1 through bolts, and the output shaft of the lifting motor 21 is fixedly connected to the top of the lead screw 22. Two guide rods 24 are installed on both sides of the lead screw 22 and are located on the outer side of the U-shaped structure of the column 1. The guide rod 24 is installed parallel to the lead screw 22. The connecting seat 23 is slidably installed on the lead screw 22 through a lead screw nut (not shown), and the connecting seat 23 is connected to the guide rod 24 through a linear bearing (not shown). When the lifting motor 21 rotates, the connecting seat 23 is driven to rise or fall along the column 1 through the lead screw 22. The setting of the two guide rods 24 can improve the stability of the lifting of the connecting seat 23. Preferably, sprockets are fixed to the lower ends of the two lead screws 22 respectively, and the two sprockets are connected by a chain 25 to realize transmission between the two lead screws 22, thereby realizing synchronous lifting and lowering of the two connecting seats 23.

[0028] like Figure 4-5 As shown, the lower platform 3 includes a connecting plate 31 and a lower frame 32 fixed to one side of the connecting plate 31. The connecting plate 31 is a rectangular steel plate, and the connecting plate 31 is connected to the connecting seat 23 by bolts. The lower frame 32 is a wedge-shaped frame welded from square tubes. The lower frame 32 is welded and fixed to the side of the connecting plate 31 away from the connecting seat 23. The bottom of the lower frame 32 is a plane, and the top surface of the lower frame 32 is an inclined surface. The side of the inclined surface away from the column 1 is lower than the side close to the column 1. A guide groove 33 is provided on the upper side of the lower frame 32. The guide groove 33 is formed by welding two square tubes at intervals.

[0029] like Figure 6 , Figure 7 As shown, the upper platform 4 includes an upper frame 41 and a bottom plate 42. The upper frame 41 is a wedge-shaped frame formed by welding square tubes. The bottom surface of the upper frame 41 matches the top surface of the lower frame 32 and the top of the upper frame 41 is a horizontal plane. The bottom plate 42 is fixedly installed on the upper side of the upper frame 41. The bottom plate 42 is provided with anti-slip grooves to prevent operators from slipping. A guide block 43 is welded to the bottom of the upper frame 41. The position of the guide block 43 matches the guide groove 33, thereby ensuring that the upper platform 4 moves along the axis perpendicular to the lower platform 3.

[0030] like Figure 6-8 As shown, rollers 44 are installed on both sides of the square tube at the lower side of the upper frame 41, and the rollers 44 at least partially extend out of the lower surface of the square tube, so that the rollers 44 abut against the square tubes at both sides of the guide groove 33. Anti-slip wheels 45 are installed on both sides of the guide block 43, respectively, and the anti-slip wheels 45 abut against the lower sides of the square tubes at both sides of the guide groove 33, thereby preventing the upper platform 4 from slipping and ensuring the installation of the equipment.

[0031] like Figure 2 , Fig. 9 As shown, the traction mechanism 6 is installed on the connecting plate 31, and the traction mechanism 6 includes a driving motor 61, a winch 62 and a rope 63. The two winches 62 are respectively installed on the back side of the connecting plate 31 through bearing seats 64, and the driving motor 61 is installed between the two winches 62. The driving motor 61 is a hollow shaft motor. The driving shaft 65 passes through the hollow shaft motor and is respectively connected to the rotation center of the two winches 62. The rope 63 is wound around the winch 62, and one end of the rope 63 passes through the connecting plate 31 and is fixedly connected to the side of the upper frame 41 close to the connecting plate 31.

[0032] The working principle of the embodiment of the present application is as follows:

[0033] When the driving motor drives the winch to unwind, the upper platform slides downward along the inclined surface of the lower platform and extends outward, so that the upper platform is close to the vehicle body;

[0034] When the driving motor drives the winch to reel in, the upper platform slides upward along the inclined surface of the lower platform and shrinks inward, so that the upper platform is away from the vehicle body.

[0035] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0036] The lifting platform is divided into a lower platform body connected to the lifting mechanism and an upper platform body that can extend along the inclined surface of the lower platform body toward the side away from the column, thereby achieving adjustment of the extension distance of the lifting platform to adapt to the operation of vehicles of different widths and improving the application range of the lifting platform.
