Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, and in particular to a skid anti-derailment system for the PVC primer coating section of automobile painting. Background Technology

[0002] During the spraying process between various workstations after electrophoresis in the painting workshop, the cab is coated by a skid moving on a roller bed. In the PVC primer section, anti-stone chip coating is sprayed onto the wheel covers under the vehicle's floor. The roller bed is above the workers. When spraying the bottom of the cab, the skid and the cab need to move continuously. If the skid derails, the cab will tip over, threatening the lives of the workers. Stable operation of the cab cannot be guaranteed in this section.

[0003] The main reasons for the skid derailing during operation on the rolling bed are as follows:

[0004] 1. When using a forklift to move the cab and the skid, the skid outriggers may deform slightly, which could lead to the skid derailing risk.

[0005] 2. Wear or damage to the rollers and bearings of the rolling mill can cause imbalance in the slide rails, leading to the risk of the slide rails derailing.

[0006] Since the PVC primer coating section operates at the bottom of the cab, if the skid derails, it will not only cause the cab to overturn and deform, but may also lead to serious personal safety accidents. Therefore, it is imperative to design a safe and efficient skid anti-derailment system. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a skid anti-derailment system for the PVC primer coating section of automotive painting.

[0008] This utility model is achieved using the following technical solution:

[0009] A skid anti-derailment system for PVC primer coating section in automotive painting includes several roller beds connected end to end. Each set of roller beds has guide wheels on both sides of the first end, and each set of roller beds has two skid anti-derailment devices on both sides. The roller bed is equipped with skids.

[0010] Furthermore, the skid anti-derailment devices are spaced apart on both sides of each set of roller beds, and the distance between two skid anti-derailment devices on the same side of the roller bed is 1200mm.

[0011] Furthermore, the distance between the head and tail of each set of roller beds and the adjacent skid anti-derailment device is 900mm.

[0012] Furthermore, the skid anti-derailment device has a T-shaped structure.

[0013] Furthermore, the material of the skid anti-derailment device is 45# steel.

[0014] Furthermore, the bottom of the skid anti-derailment device is located on both sides of the roller bed, and the distance between the top of the skid anti-derailment device and the bed surface of the roller bed is 170mm.

[0015] Furthermore, the surface of the skid anti-derailment device is provided with a corrosion-resistant coating.

[0016] Furthermore, the rolling bed is provided with rollers, and the skid is located at the upper end of the rollers.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] Two roller beds connected end to end are equipped with guide wheels on both sides of the first end of each roller bed. This forces the sled to run precisely along the preset track, preventing the sled from derailing, jamming, or colliding with other equipment. This ensures the continuous, stable, and reliable operation of the conveying system in the PVC primer section, reduces downtime, and the wear on the guide edge of the sled due to rolling contact is much less than that of sliding friction, thus extending the service life of the sled.

[0019] The anti-derailment device restricts the lateral displacement of the derailed skid. When the skid accidentally derails from the predetermined track due to reasons such as guide wheel failure, severe wear, foreign object jamming, positioning error, drive asynchrony or external impact, the skid anti-derailment device will act as a physical barrier. It prevents the derailed skid from continuing to move outward (away from the center line of the roller bed), roll or fall, and restrains it within a relatively controllable range to prevent the skid from completely rushing out of the roller bed.

[0020] To prevent cascading damage to equipment, a derailed skid, if moved unrestricted, could violently impact, pull, or crush nearby critical equipment (such as adjacent roller beds, elevators, transfer machines, stoppers, sensors, cable trays, pneumatic / hydraulic pipelines, robot workstation bases, etc.). Skid anti-derailment devices can absorb or buffer some of the impact energy, significantly reducing the risk of secondary damage to surrounding expensive equipment.

[0021] Protecting personnel safety is paramount, as out-of-control skids (especially those carrying vehicles) possess immense kinetic energy and pose a significant danger. Skid derailment prevention devices constitute a safety boundary, preventing derailed skids from entering personnel safety passages or work areas, thus reducing the risk of personal injury accidents.

[0022] Facilitating fault handling and safe reset, the derailment skid is confined to a relatively fixed area, allowing maintenance personnel to locate the fault point more quickly and safely, and use jacks, lifting tools and other tools to safely and efficiently reset the skid back onto the track, reducing downtime.

[0023] The skid anti-derailment device works in conjunction with the guide wheels. The guide wheels (active contact type) are the first line of defense against skid derailment and are responsible for precise guidance during daily operation. The skid anti-derailment device is the last passive line of defense, specifically designed to deal with extreme situations where the guidance system fails. Together, they constitute a complete skid operation safety guarantee system. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] like Figure 1-4 As shown, a skid anti-derailment system for PVC primer coating section in automotive painting includes several roller beds 3 connected end to end. Each set of roller beds 3 has guide wheels 2 on both sides of the head end, and two skid anti-derailment devices 1 on both sides of each set of roller beds 3. The roller bed 3 is equipped with skids 5.

[0032] The anti-derailment device 1 of the skid is arranged at intervals on both sides of each set of roller beds 3, and the distance between the two anti-derailment devices 1 of the skid on the same side of the roller bed 3 is 1200mm.

[0033] The distance between the head and tail of each set of roller beds 3 and the adjacent skid anti-derailment device 1 is 900mm.

[0034] The skid anti-derailment device 1 has a T-shaped structure.

[0035] The material of the skid anti-derailment device 1 is 45# steel.

[0036] The bottom of the skid anti-derailment device 1 is located on both sides of the roller bed 3, and the distance between the top of the skid anti-derailment device 1 and the bed surface of the roller bed 3 is 170mm.

[0037] The surface of the skid anti-derailment device 1 is coated with a corrosion-resistant coating.

[0038] The roller bed 3 is equipped with rollers 4, and the skid 5 is located on the upper end of the rollers 4.

[0039] When the skid 5 carrying the cab enters the roller bed 3 of the PVC primer coating section, guide wheels 2 are installed on both sides of the entrance at the front end of the roller bed 3 to guide the skid 5 onto the rollers 4 with fixed tracks installed on the roller bed 3. At the same time, the skid 5 enters under the skid anti-derailment device 1 set on both sides of the roller bed 3 to prevent the skid 5 from derailing during its operation.

During the handover, the skid 5 first corrects its position by the guide wheels 2, and then the rollers 4 installed on the roller bed 3 transport the skid 5 and the cab above it to the designated position. At the same time, the skid 5 enters between the top of the skid anti-derailment device 1 set on both sides of the roller bed 3 and the bed surface of the roller bed 3.
