Technical Field

[0001] The utility model belongs to the technical field of equipment safety, and particularly relates to an adjustable industrial machinery safety protection cover. Background Art

[0002] During the operation of large mechanical equipment, a protective cover is required on the periphery of the machine. On the one hand, it protects the normal operation of the machine, and on the other hand, it can ensure the safety of the staff during the production process, preventing the production staff from contacting the operating mechanical equipment. Especially under the high operating cost of large mechanical equipment, it is very necessary to install a protective cover.

[0003] At present, the most commonly used protective covers are welded by steel plate structures and wire meshes, or steel plates and accordion protective covers, as well as rubber protective covers, steel plates and stainless steel protective covers. They have good sealing performance, can prevent iron filings, coolant, and accidental accidents, and are strong and durable. However, when the staff performs maintenance, replacement of parts, equipment repair, regular maintenance, and regular inspection on the mechanical equipment inside the protective cover, and when the current machinery requires professional personnel to adjust, lubricate, clean, and spot-check the equipment components inside the protective cover during the running state, a large number of staff and labor time are required to disassemble and assemble the protective cover, reducing work efficiency.

[0004] Therefore, the Chinese utility model patent CN201820057437.2 discloses a protective cover for mechanical equipment, which includes a base, a plug hinge, and a micro elevator. The top surface of the base is fixedly installed with a protective strip frame body. The protective strip frame body is fixedly installed with a protective baffle, a top plate, and a glass baffle through the plug hinge. An operating platform is arranged on the surface of the front glass baffle, and a key is fixedly installed below the operating platform. The plug hinge includes a pin hole and a pin rod. The pin rod is detachably installed in the pin hole. The motor is fixedly installed on the motor base. The motor is meshed with a threaded rod gear. The motor and the key are electrically connected. The carrying platform is meshed with the threaded rod gear. The carrying platform is fixedly connected with the glass baffle. The utility model has a simple structure, novel design, practical and safe, uses baffles of different materials, and can be quickly disassembled and assembled by using a plug hinge.

[0005] Although the above patent solves the problem of troublesome installation and disassembly of the existing equipment protective cover to a certain extent, this type of protective cover is still a fixed-volume protective cover, which cannot cope with the current complex and changeable maintenance working conditions. When the space is narrow during maintenance, it still needs to be disassembled as a whole, and there are certain deficiencies in use. In addition, this type of protective cover can only be used for one machine at a time and needs to be customized by contacting the manufacturer, and cannot be produced modularly and in large quantities, and the versatility is insufficient. Summary of the Utility Model

[0006] The purpose of the present utility model is to disclose an adjustable industrial machinery protective cover to make up for the deficiencies of the above-mentioned existing technologies and improve the practicability of the equipment protective cover.

[0007] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0008] An adjustable industrial machinery safety protective cover includes a protective cover mounting seat. On both the left and right sides of the protective cover mounting seat, three guide rails are arranged in parallel from outside to inside. The first protective cover is fixedly installed on the two innermost guide rails, the second protective cover is slidably connected to the two middle guide rails, and the third protective cover is slidably connected to the two outermost guide rails. Moreover, the volumes of the first protective cover, the second protective cover, and the third protective cover gradually increase, and they are sleeved in sequence according to the volume order to form a combined telescopic protective cover.

[0009] Compared with the existing technology, the present utility model has the following beneficial effects:

[0010] The present utility model solves the problem that the installation and disassembly of the existing equipment protective cover are troublesome. During maintenance, it only needs to open the maintenance safety door and fold the protective cover in sequence, which saves time and effort and improves work efficiency. At the same time, this type of protective cover is suitable for the safety protection of industrial mechanical equipment of different sizes, and the length of the protective cover can be flexibly adjusted according to the current size of the equipment, improving the practicability of the device.

[0015] The following further explains the present utility model with reference to the drawings.

[0016] As Figures 1-3As shown in the figure, an adjustable safety shield for industrial machinery includes a shield mounting base 1. On both the left and right sides of the shield mounting base 1, three guide rails 2 are arranged in parallel from the outside to the inside. A first shield 3 is fixedly installed on the two innermost guide rails. A second shield 4 is slidably connected to the two middle guide rails. A third shield 5 is slidably connected to the two outermost guide rails. Moreover, the volumes of the first shield 3, the second shield 4, and the third shield 5 gradually increase, and they are sleeved in sequence according to the volume order to form a combined telescopic shield.

[0017] The first shield 3, the second shield 4, and the third shield 5 all adopt a frame-type arched structure. PVP plates are installed inside the frames. And limit blocks 6 are arranged at both the front and rear ends of the outer sides of the first shield 3 and the second shield 4.

[0018] The rear end of the first shield 3 is blocked by a PVP plate. A maintenance safety door 7 is installed at the front end of the third shield 5. At the same time, in order to prevent the third shield from retracting backward after the maintenance safety door is closed, a check block 8 for restricting the retraction of the third shield is also installed on the two middle guide rails.

[0019] During installation, first install the shield mounting base 1 made of aluminum profiles around the mechanical equipment. Then, on the left and right sides of the shield mounting base 1, three guide rails are arranged in parallel from the outside to the inside. Next, install the frame-type first shield 3, second shield 4, and third shield 5 on the guide rails 2. Note that the first shield 3 is directly fixed at the end of the guide rail 2, and the second shield 4 and the third shield 5 are slidably connected to the guide rails. After the installation is completed, check whether the second shield 4 and the third shield 5 can slide freely. After checking without errors, block the rear end of the first shield 3 with a PVP plate, install the maintenance safety door 7 at the front end of the third shield 5. Finally, according to the positions of the second shield 4 and the third shield 5 after they are extended, install the limit blocks 6 and the check block 8.

[0020] When in use, first pull out the third protective cover 5. After the third protective cover 5 moves forward one cover body position, the inner side of the rear end of the cover body of the third protective cover 5 hooks the limit block 6 located on the outer side of the front end of the second protective cover 4, and the second protective cover 4 is pulled forward as well. After the second protective cover 4 also moves forward one cover body position, the representative device has reached the maximum length. At this time, the inner side of the cover body of the rear end of the second protective cover 4 hooks the limit block 6 located on the outer side of the front end of the first protective cover 3, and the maintenance safety door 7 is closed. After the maintenance safety door 7 is closed, the inner side of the door frame just conflicts with the check block 8, thereby limiting the retraction of the third protective cover 5. When equipment maintenance is required, open the maintenance safety door 7 and push back the third protective cover 5. After the cover body of the third protective cover 5 moves backward by one cover body position, the outer side of the rear end of the cover body of the third protective cover 5 conflicts with the limit block 6 located on the outer side of the rear end of the second protective cover 4, driving the second protective cover 4 to move backward together. After the second protective cover 4 also moves backward by one cover body position, the outer side of the rear end of the cover body of the second protective cover 4 conflicts with the limit block 6 located on the outer side of the rear end of the first protective cover 3, indicating that the device is folded to the smallest volume and maintenance operations can be carried out.

[0021] During the above working process, the overall telescopic length of the device can be adjusted as needed, and there is no need to make maximum and minimum adjustments each time according to the above requirements. An observation window is provided on the maintenance safety door 7 to facilitate monitoring of the operation of the mechanical equipment in the protective cover.
