Description

Technical Field

[0001] This utility model relates to the field of hoisting technology for sheet metal spraying, and more specifically, to a hoisting device for sheet metal spraying. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. Currently, sheet metal parts need to undergo a painting process to enhance their corrosion resistance and optimize their mechanical properties. Before the painting process, sheet metal parts need to be suspended and placed, and hoisting equipment is used to assist in the transfer to complete the painting operation.

[0003] Currently, sheet metal parts cannot rotate automatically after being hung on the hanger in sequence. They require manual assistance to rotate them one by one to complete the painting process. At the same time, the position of the hanger cannot be adjusted according to the specific size of the sheet metal parts to ensure stable placement. Therefore, the effectiveness of the sheet metal part painting suspension device needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a hoisting device for sheet metal spraying.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A lifting device for sheet metal spraying includes a mounting rod, lifting rings, mounting rollers, a gear transmission assembly, a suspension rod, a through hole, and steel wire.

[0007] The lifting ring is welded to the mounting rod and is matched with the anti-detachment hook of the lifting equipment;

[0008] The mounting roller is rotatably connected to the mounting rod;

[0009] The gear transmission assembly is fixed on the mounting rod and is connected to the mounting roller;

[0010] Several suspension rods are spaced apart and parallel to each other on the mounting rollers;

[0011] Several through holes are made on the suspension rod, and steel wires are fitted inside the through holes to suspend multiple sheet metal parts alternately on a suspension rod.

[0012] Furthermore, the uppermost suspension rod is welded to the mounting roller, and the remaining suspension rods are movably connected to the mounting roller.

[0013] Furthermore, each of the remaining suspension rods is welded with a fixing ring, and an installation roller is inserted into the fixing ring. The fixing ring has a first threaded hole, and the installation roller has several second threaded holes with the same diameter as the first threaded hole. The fixing bolt passes through the first threaded hole and engages with one of the second threaded holes.

[0014] Furthermore, sheet metal parts are hung in the central area of ​​the suspension rod away from the mounting roller, and sheet metal parts are hung in the two sides of the suspension rod closer to the mounting roller.

[0015] Furthermore, the diameter of the steel wire is 2-3 times the thickness of the sheet metal part.

[0016] Furthermore, both ends of the steel wire are bent, and the bent areas are threaded, with anti-loosening nuts fitted on the threads.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0024] like Figure 1As shown, a sheet metal spraying hoisting device includes a mounting rod 1, a lifting ring 2, a mounting roller 3, a gear transmission assembly 4, a suspension rod 5, a through hole 6, and a steel wire 7.

[0025] The lifting ring 2 is welded to the mounting rod 1 and the lifting ring 2 is matched with the anti-detachment hook of the lifting equipment (the lifting equipment is specifically a crane trolley);

[0026] The mounting roller 3 and the mounting rod 1 are rotatably connected by bearings;

[0027] The gear transmission assembly 4 is fixed on the mounting rod 1, and the gear transmission assembly 4 is connected to the mounting roller 3;

[0028] Several suspension rods 5 are spaced apart and parallel to each other on the mounting roller 3;

[0029] Several through holes 6 are provided on the suspension rod 5, and steel wires 7 are fitted inside the through holes 6 to suspend multiple sheet metal parts alternately on a suspension rod 5.

[0030] To reduce mutual interference between several sheet metal parts hanging on the same suspension rod 5 during the rotary spraying process, the above scheme is further optimized by placing sheet metal parts in the central area of ​​the side of the suspension rod 5 away from the mounting roller 3, and placing sheet metal parts in the two side areas of the suspension rod 5 closer to the mounting roller 3.

[0031] To prevent the sheet metal from detaching from the wire 7 or the wire 7 from the through hole 6 during rotation, the above embodiment is further optimized by making the diameter of the wire 7 2-3 times the thickness of the sheet metal (this can prevent the wire from deforming during the rotation and spraying of the sheet metal). Both ends of the wire 7 are bent, and the bent area is provided with threads. Anti-loosening nuts are fitted on the threads. The threads and anti-loosening nuts are not shown in the figure.

[0032] The working process of this utility model is as follows:

[0033] First, several steel wires 7 are installed on the suspension rods 5 of each layer. Then, multiple sheet metal parts can be hung on each suspension rod 5. Specifically, the pre-drilled holes on the sheet metal parts pass through the ends of the steel wires 7, and the initial ends of the steel wires 7 pass through the through holes 6 to get support. It should be noted that the steel wires 7 are selectively installed according to the size of the sheet metal parts. The steel wires 7 can be installed in each through hole 6, or they can be installed at intervals of one or more through holes 6. Large sheet metal parts are hung by multiple steel wires 7 (one can be hung on one suspension rod 5), while small sheet metal parts can be hung by one steel wire 7 (multiple can be hung on one suspension rod 5).

[0034] After multiple sheet metal parts are hung on several layers of suspension rods 5, anti-loosening nuts are installed at both ends of the steel wire 7 to prevent the steel wire 7 from coming off the through hole 6 or the sheet metal parts from coming off the steel wire 7. Then, the gear transmission assembly 4 (which belongs to the prior art and consists of a servo motor, a main gear and a secondary gear) is started to drive the multiple sheet metal parts to rotate slowly at a uniform speed. Then, the sheet metal parts are transferred to the spraying area by the hoisting equipment to complete the spraying (the specific spraying area is equipped with multiple spray nozzles on both sides away from the sheet metal parts, and the spraying process is not described in this application). In addition, the servo motor in the gear transmission assembly 4 is powered by a storage battery, which is installed on the mounting rod 1. The storage battery is not shown in the figure.

[0035] After completing the concentrated spraying of the sheet metal parts, first move the hanger away from the spraying area, then remove the anti-loosening nut and replace it with the next sheet metal part to be sprayed. This will improve the effectiveness of the sheet metal part spraying suspension hanger.

[0036] To further expand the range of sheet metal parts that this lifting device can hang, in some embodiments, such as Figure 2 As shown, the uppermost suspension rod 5 is welded to the mounting roller 3, and the remaining suspension rods 5 are movably connected to the mounting roller 3;

[0037] In a further refinement of the above embodiment, each of the remaining suspension rods 5 is welded with a fixing ring 8, and an installation roller 3 is inserted into the fixing ring 8. The fixing ring 8 has a first threaded hole 9, and the installation roller 3 has several second threaded holes 10 with the same diameter as the first threaded hole 9. The fixing bolt 11 passes through the first threaded hole 9 and engages with one of the second threaded holes 10. In this embodiment, when the size of the sheet metal parts to be hung is large, the distance between adjacent suspension rods 5 can be increased sequentially to allow large sheet metal parts to be loaded without obstruction. At the same time, if the size of the sheet metal parts is small, the distance between adjacent suspension rods 5 can be decreased sequentially and more suspension rods 5 can be added to hang more sheet metal parts.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
