Description

Technical Field

[0001] This utility model relates to the field of electrophoresis hanger technology, and in particular to a trolley structure for electrophoresis hangers. Background Technology

[0002] In electrophoretic coating production lines, electrophoretic hangers are the core carriers connecting various processing steps of the workpiece. They need to carry the workpiece frequently between multiple stations such as pretreatment tanks, electrophoretic tanks, and curing ovens. The hangers themselves often integrate multiple rows of hooks, support arms, and other structures. They are irregular in shape and a single set can weigh tens of kilograms. After the workpiece is hung, the overall center of gravity is more likely to shift. Currently, the industry generally uses manual handling or ordinary flatbed trucks to complete the transfer of hangers. These two methods are the mainstream traditional operation modes.

[0003] However, the aforementioned traditional transfer methods have many prominent technical problems: manual handling is extremely labor-intensive, and only 1-2 sets of hangers can be moved at a time, which seriously restricts the production cycle. Moreover, during the handling process, the hangers are prone to shaking due to uneven force applied by the hands, which can cause the hooks to be bumped and deformed or the surface protective layer to fall off, directly affecting the positioning accuracy of subsequent workpieces. Although ordinary flatbed carts can carry more hangers, due to the lack of a suitable limiting structure, the hangers can only be stacked haphazardly. During the transfer, the hangers will collide violently due to the bumps on the workshop floor, which will not only aggravate the wear and tear of the hangers themselves, but also easily cause the workpieces to fall off or be scratched when small workpieces are already attached to the hangers, directly leading to product scrapping and causing unnecessary production losses to the enterprise. Utility Model Content

[0004] In view of the problems of high labor intensity, low transfer efficiency, easy bumping and deformation of the hangers, easy detachment and scrapping of the hung workpieces and increased wear and tear on the hangers in the existing traditional methods of manual handling or transportation with ordinary flatbed trucks, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a trolley structure for an electrophoresis hanger, including a base frame, universal wheels are rectangularly distributed at the bottom of the base frame, support frames are symmetrically arranged at the top of the base frame, a first crossbar is installed between the two support frames, and the first crossbar is located on the side of the support frame away from the base frame, a guide rail is provided at the top of the first crossbar, and an electrophoresis hanger body is provided below the first crossbar and movably connected to the guide rail.

[0006] As a preferred embodiment, the electrophoresis apparatus body includes a hook, which is slidably sleeved on the outside of the guide rail. A vertical rod is connected to the lower end of the hook. Several second horizontal bars are provided on one side of the vertical bar. Several support rods are symmetrically provided on both sides of the second horizontal bars, and a triangular piece is connected to the end of the support rod away from the second horizontal bar.

[0007] As a preferred embodiment, connecting rods are provided symmetrically on both sides of the vertical rod, and the connecting rods are fixedly connected to several second horizontal rods. The lower ends of the connecting rods and the vertical rods are connected to a fixing rod.

[0008] As a preferred embodiment, support rods are symmetrically provided below the fixed rod, and the support rods are fixedly connected to the fixed rod and the connecting rod respectively.

[0009] As a preferred embodiment, the guide rail has an L-shaped cross-section, the hook has a hook-shaped structure, the support frame has a trapezoidal shape, and the support frame has handrails symmetrically arranged on the outer side.

[0010] As a preferred embodiment, the bottom frame is provided with diagonal braces symmetrically distributed at the four corners, and both ends of the diagonal braces are fixedly connected to the bottom frame. The caster wheel is equipped with a brake structure.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] 1. This utility model uses universal wheels with brakes at the bottom of the base frame and handrails on the outside of the support frame to easily push the trolley to realize the multi-station transfer of the hanging fixtures, replacing manual handling; at the same time, with the cooperation of guide rails and hooks, multiple sets of electrophoresis hanging fixtures can be centrally suspended and stored, and the single transfer volume far exceeds 1-2 sets that can be manually handled, effectively improving the production cycle.

[0013] 2. With the cooperation of guide rails and hooks, the electrophoresis hanger body can be orderly suspended on the trolley, avoiding the problems of hanger collision, hook deformation and protective layer falling off caused by disorderly stacking of ordinary flatbed carts. At the same time, the support rod of the hanger provides stable support when placed on the ground, and the trolley is suspended by hooks during transportation. The dual structure design can prevent the hanger and the small workpieces it is loaded from falling off or scratching during circulation and storage, reducing product scrap and hanger damage.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 - Figure 4 As shown, a trolley structure for electrophoresis hangers is provided, including a base frame 1. Universal wheels 2 are rectangularly distributed at the bottom of the base frame 1. Support frames 4 are symmetrically arranged at the top of the base frame 1. A first crossbar 6 is installed between the two support frames 4, and the first crossbar 6 is located on the side of the support frame 4 away from the base frame 1. A guide rail 7 is provided at the top of the first crossbar 6, and an electrophoresis hanger body 16 movably connected to the guide rail 7 is located below the first crossbar 6. The combination of the base frame 1, universal wheels 2, support frames 4, first crossbar 6, and guide rail 7 provides a stable installation and load-bearing foundation for the electrophoresis hanger body 16, enabling centralized transport of the hangers, replacing manual handling, and significantly improving transport efficiency.

[0022] In this example, the electrophoresis hanger body 16 includes a hook 8, which is slidably sleeved on the outside of the guide rail 7. A vertical rod 9 is connected to the lower end of the hook 8. Several second horizontal rods 10 are provided on one side of the vertical rod 9. Several support rods 12 are symmetrically provided on both sides of the second horizontal rods 10, and a triangular piece 13 is connected to the end of the support rod 12 away from the second horizontal rod 10. The sliding cooperation between the hook 8 and the guide rail 7 can realize the orderly suspension and position adjustment of the electrophoresis hanger body 16, avoiding disorderly stacking of the hangers. At the same time, the structural design of the second horizontal rods 10, support rods 12 and triangular pieces 13 can stably support the workpiece and reduce the shaking during the transfer of the workpiece.

[0023] In this example, connecting rods 11 are provided symmetrically on both sides of the vertical rod 9, and the connecting rods 11 are fixedly connected to several second horizontal rods 10. The lower ends of the connecting rods 11 and the vertical rod 9 are connected to a fixing rod 14. The connecting rods 11 and the fixing rods 14 enhance the connection strength between the vertical rod 9 and the second horizontal rods 10, improve the overall structural stability of the electrophoresis fixture body 16, and can withstand the weight of heavy workpieces, thus avoiding fixture deformation.

[0024] In this example, support rods 15 are symmetrically provided below the fixed rod 14, and the support rods 15 are fixedly connected to the fixed rod 14 and the connecting rod 11 respectively. The support rods 15 can provide stable support when the electrophoresis hanger body 16 is placed on the ground to prevent the hanger from tipping over. Together with the suspension structure of the hook 8 and the guide rail 7, they form double protection and reduce the wear and tear on the hanger and workpiece.

[0025] In this example, the guide rail 7 has an L-shaped cross section, the hook 8 has a hook-shaped structure, the support frame 4 has a trapezoidal shape, and the support frame 4 is symmetrically provided with handrails 5 on the outer side. The matching structure of the L-shaped guide rail 7 and the hook-shaped hook 8 can prevent the hanger from falling off during transportation. The trapezoidal support frame 4 improves the load-bearing stability of the trolley, and the handrails 5 make it easier for operators to push the trolley and reduce labor intensity.

[0026] In this example, the four corners of the bottom frame 1 are symmetrically distributed with diagonal braces 3, and both ends of the diagonal braces 3 are fixedly connected to the bottom frame 1. The casters 2 are equipped with brakes. The diagonal braces 3 enhance the structural strength of the bottom frame 1 and prevent the trolley from deforming when it is under load. The casters 2 with brakes can fix the position of the trolley at any time during the transfer, prevent the trolley from sliding and causing collisions, and improve the safety of the transfer.

[0027] During use, the basic load-bearing and mobile support are as follows: The bottom frame 1 serves as the core load-bearing frame, and the diagonal braces 3 at its four corners enhance the overall structural strength, which can stably bear the weight of the hanger and the workpiece; the rectangular universal wheels 2 at the bottom of the bottom frame 1 enable the trolley to move flexibly, and with the brake structure on the universal wheels 2, the position of the trolley can be quickly fixed after being transferred to the target workstation to prevent slippage; at the same time, the trapezoidal support frame 4 symmetrically arranged at the top of the bottom frame 1 not only provides stable support for the first crossbar 6, but also optimizes the force distribution of the trolley and improves the load-bearing stability.

[0028] Hanging and positioning adjustment of the hanger: The top of the first crossbar 6 between the support frames 4 is provided with an L-shaped guide rail 7. The electrophoresis hanger body 16 is slidably sleeved on the outside of the guide rail 7 through the hook hook 8. The matching structure of the L-shaped guide rail 7 and the hook hook 8 can prevent the hanger from falling off during transportation. The operator can push the trolley through the handrail 5. The hanger can be flexibly slid along the guide rail 7 to adjust its position, so as to realize the orderly hanging and storage of multiple hangers and avoid disorderly stacking.

[0029] Workpiece bearing and structural reinforcement: In the electrophoresis hanger body 16, the vertical rod 9 at the lower end of the hook 8 is fixedly connected to several second horizontal rods 10 through the connecting rods 11 on both sides. The fixed rods 14 at the lower end of the vertical rod 9 and the connecting rods 11 further enhance the overall rigidity of the hanger, which can bear a certain weight of the workpiece without easily deforming. The support rods 12 on both sides of the second horizontal rod 10 and the triangular pieces 13 form a stable workpiece support structure, which can firmly limit the workpiece and reduce shaking during transportation.

[0030] Multi-scenario adaptation and protection: When the hanger needs to be removed from the trolley and placed on the ground, the support rods 15 symmetrically arranged below the fixing rod 14 can contact the ground to form a stable support, preventing the hanger from tipping over due to irregular shape or center of gravity shift; during transportation, the hanger is suspended through the cooperation of the hook 8 and the guide rail 7, forming a dual adaptation structure of "suspended transportation + ground support", which fully ensures the safety of the hanger and workpiece during circulation and storage.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
