Description

Technical Field

[0001] This utility model relates to a safety protection device for the maintenance of the roller system of a plate straightening machine, belonging to the technical field of safety protection for the maintenance of metallurgical equipment in the metallurgical industry. Background Technology

[0002] Plate straightening machines are important pieces of equipment on hot-rolled medium and heavy plate production lines. They are used to release internal stress in rolled plates and eliminate unevenness in steel plates, completing the straightening process of rolled plates. They are essential equipment on the production line.

[0003] like Figure 12 As shown, the roller system of the plate straightening machine consists of an upper roller system 001 and a lower roller system 002. The working roller 003 is fixed and constrained on the roller box 0011 by the pull rod 0031 on its bearing seat, the disc spring 0032 and the nut 0033. The disc spring 0032 can play a buffering role.

[0004] Maintenance work involving the upper roller system 001 and the lower roller system 002, such as inspecting and grinding the iron stuck on the surface of the straightener's working roller 003, dealing with the internal and external cooling water pipes of the roller system, and dealing with the internal lubrication joints of the roller system, usually involves opening the upper and lower roller systems to the maximum, placing support components 004 at the four corners of the upper and lower roller systems, and then having the workers crawl between the upper and lower roller systems of the straightener to carry out maintenance work.

[0005] Support component 004 is placed on the lower roller box 0021 of the lower roller system 002 and corresponds to the upper roller box 0011 of the upper roller system 001. It is used to support the upper roller system 001 in the event of a sudden fall, thus protecting the safety of workers within the roller system. However, because support component 004 supports the upper roller box 0011 of the upper roller system 001, if a work roller 003 within the upper roller system 001 suddenly falls—for example, due to a broken bearing seat tie rod 0031, failure of the threaded connection between the tie rod 0031 and the nut 0033, failure of the disc spring 0032, or a broken work roller shaft—there is no effective protective support, posing a significant safety hazard to workers within the roller system. Furthermore, support component 004 is placed on the lower roller system 002 without constraint or positioning. If its placement is improper or the roller system tilts and falls, support component 004 can easily be squeezed out of the roller system, rendering its safety protection function ineffective. Therefore, a new technical solution is urgently needed to address these problems. Utility Model Content

[0006] The purpose of this utility model is to provide a safety protection device for the maintenance of the roller system of a plate straightening machine, so as to achieve stable safety protection support for the entire roller system of the straightening machine and any single working roller, and solve the problems existing in the background art.

[0007] The technical solution of this utility model is: A safety protection device for maintenance of the roller system of a plate straightening machine includes a support frame, V-shaped brackets, a base, pads, and safety supports. The support frame is fixed on the base, and pads are provided under the base. The support frame is provided with several V-shaped brackets that cooperate with the upper roller system of the straightening machine. The safety supports are set between the upper and lower roller systems of the straightening machine.

[0008] The support frame has several V-shaped brackets that cooperate with the roller system of the straightener and correspond to the working rollers of the roller system on the straightener.

[0009] The support frame is provided with several thin-walled circular tubes evenly arranged, and the spacing between them is consistent with the center distance of the working rollers of the upper roller system. A guide circular tube is provided below the V-shaped support and is inserted into the thin-walled circular tubes.

[0010] The support frame is equipped with handles A at both ends, and also has multiple weight-reducing grooves.

[0011] The base is a cuboid structure with multiple arc grooves evenly distributed below it. The spacing between the arc grooves is consistent with the center distance of the working rollers of the lower roller system, and the radius of curvature of the arc grooves is consistent with the radius of the working rollers of the lower roller system.

[0012] The base has symmetrical trapezoidal grooves of a certain depth at both ends below, and a trapezoidal boss is provided above the pad, the cross-section of which is consistent with the trapezoidal groove of the base.

[0013] The safety support is equipped with a centering block.

[0014] The safety support is a hollow cylinder, and the center block is a stepped cylinder that matches the safety support, with a countersunk bolt hole in the center.

[0015] The safety support has an inner chamfer at the top and an outer chamfer at the bottom, and a handle B on the side.

[0016] The beneficial effects of this utility model are: the device has the advantages of simple structure, convenience and speed, light weight, safety, stability and reliability. It can form a stable safety prevention support for any single working roll of the upper roller system of the straightening machine, effectively solving the problem of no effective safety protection for workers in the event of a single working roll falling suddenly; it can form a stable safety prevention support for the upper roller system of the straightening machine, effectively solving the problems of skew caused by the lack of effective constraint and positioning when the upper roller system falls, the lack of positioning of safety support and easy squeezing and misalignment, and the failure of safety support, and can effectively ensure the safety of maintenance workers in the roller system of the straightening machine.

[0018] The present invention will be further described below with reference to the accompanying drawings and examples.

[0019] See attached document Figure 1-11A safety protection device for maintenance of the roller system of a plate straightening machine includes a support frame 1, a V-shaped bracket 2, a base 3, a pad 4, and a safety support 5. The support frame 1 is fixed on the base 3, and the pad 4 is provided under the base 3. The support frame 1 is provided with a plurality of V-shaped brackets 2 that cooperate with the upper roller system 001 of the straightening machine. The safety support 5 is set between the upper roller system 001 and the lower roller system 002 of the straightening machine.

[0020] In this embodiment, as Figure 1 As shown, this utility model provides a safety protection device for the maintenance of the roller system of a sheet metal straightening machine, mainly including a support frame 1, a V-shaped bracket 2, a base 3, a pad 4, a safety support 5, a centering block 6, and an internal hex bolt 7, wherein: like Figure 2 As shown, a C-shaped channel steel 101 is provided below the support frame 1. Multiple thin-walled round tubes 102 are evenly distributed above the C-shaped channel steel 101, with their spacing consistent with the center distance of the working rollers 003 of the upper roller system 001. The thin-walled round tubes 102 are perpendicular to the upper surface of the C-shaped channel steel 101 and can bear the weight of a single working roller 003. Handles A103 are provided at both ends of the C-shaped channel steel 101, and multiple weight-reducing grooves 104 are provided on the body of the C-shaped channel steel 101.

[0021] like Figure 3 As shown, the V-shaped support 2 consists of a support plate 201, a V-shaped baffle 202, and a guide tube 203. The support plate 201 is a rectangular plate, and a guide tube 203 composed of thin-walled round tubes is provided below it, maintaining a perpendicular relationship with it. The outer diameter of the guide tube 203 is consistent with the inner diameter of the thin-walled round tube 102 of the support frame 1, and the two are fitted with a clearance. Above the support plate 201, there is a V-shaped baffle 202 composed of two symmetrical rectangular plates at a certain angle to it. The support plate 201 supports the straightener's work roll 003, and the V-shaped baffle 202 constrains and positions it, so that the work roll 003 can maintain a tangential relationship with the support plate 201 and the V-shaped baffle 202.

[0022] like Figure 4 As shown, the base 3 has a rectangular structure and is made of wood. It has a boss 301 on top, and the structure of the boss 301 matches the C-shaped groove of the C-shaped channel steel 101 of the support frame 1. Multiple arc grooves 302 are evenly distributed below it, and their spacing is consistent with the center distance of the working rollers 003 of the lower roller system 002. The radius of curvature of the arc grooves 302 is consistent with the radius of the working rollers 003. Trapezoidal cross-section grooves 303 with a certain depth are symmetrically provided at both ends below it.

[0023] like Figure 5As shown, the pad 4 is made of wood, with a rectangular base plate 401 at its bottom and a trapezoidal cross-section boss 402 on top. The boss's cross-section matches the interface of the trapezoidal cross-section groove 303 of the base 3. The width of the pad 4 matches the width of the base 3, and the length of the pad 4 matches the depth of the trapezoidal cross-section groove 303 of the base 3. The trapezoidal cross-section boss 402 of the pad 4 is installed within the trapezoidal cross-section groove 303 of the base 3 to support the base 3 and increase its overall height.

[0024] like Figure 6 As shown, the V-shaped bracket 2 is installed inside the thin-walled circular tube 102 of the support frame 1. The support frame 1 is installed above the base 3, and the pad 4 is installed below the base 3, forming a work roller bracket. Through the matching and assembly of its component thickness, height, weight, etc., it maintains a small safety distance with the work roller 003 of the upper roller system 001, forming a stable preventive support. At the same time, the components are assembled within the roller system, ensuring the overall height and preventing interference between the V-shaped baffle 202 of the V-shaped bracket 2 and the work roller 003 of the upper roller system 001 during the process of pushing it into the roller system. Dividing the work roller bracket into four components facilitates the handling and assembly of the components by the operators, avoiding the inability to install a single component due to its heavy weight. At the same time, the support frame 1 has multiple weight-reducing grooves 104, and the base 3 and pad 4 are made of wood to reduce weight.

[0025] The support frame 1 with the V-shaped bracket 2 can be placed on the roller system, so that the V-shaped bracket 2 corresponds to the working roller 003 of the upper roller system 001. The support frame 1 is lifted and placed into the base 3 along the C-shaped groove of the support frame 1. Pad blocks 4 are installed in the trapezoidal cross-section grooves 303 at both ends of the base 3. The whole is located above the working roller 003 of the lower roller system 002 and is supported by the pad blocks 4 placed on the front and rear guard plates of the lower roller box 0021 of the lower roller system 002. The V-shaped bracket 2 corresponds to the working roller 003 of the upper roller system 001 and maintains a small distance without contact. The arc groove 302 below the base 3 corresponds to the working roller 003 of the lower roller system 002 and maintains a small distance without contact. This forms a stable preventive support for each working roller 003 of the upper roller system 001 and plays a safety protection role.

[0026] like Figure 7 As shown, the safety support 5 is made of thick-walled round tube and can bear the weight of the roller system 001 and its upper parts on the straightener. It is used for safety support in case the roller system falls suddenly. It has an inner chamfer 501 at a certain angle above it, an outer chamfer 502 at a certain angle below it, and a handle B503 on the side.

[0027] like Figure 8As shown, the center block 6 is provided with a circular boss 601, and the boss has an outer chamfer 6011 at a certain angle, and a countersunk bolt hole 602 inside. The size and angle of the outer chamfer 6011 of the circular boss 601 match the inner chamfer 501 of the safety support 5.

[0028] like Figure 9 As shown, internal threaded holes can be added at the four symmetrical positions on the outer side of the upper roller box 0011 of the upper roller system 001, and the centering block 6 can be installed on the upper roller box 0011 of the upper roller system 001 by means of internal hex bolts 7; circular grooves 00211 can be added at the corresponding positions on the four corners of the lower roller box 0021 of the lower roller system 002, the size of the circular grooves 00211 is consistent with the outer diameter of the safety support 5, and is used to constrain and position the safety support 5.

[0029] like Figure 9-10 As shown, the axes of the centering block 6, the safety support 5, and the circular groove 00211 coincide. Through the inner and outer guide angles on the centering block 6 and the safety support 5, and the constraint positioning of the safety support 5 and the circular groove 00211 on the lower roller system, the centering block 6 on the upper roller system 001 can smoothly enter the safety support 5, avoiding misalignment or tilting of the safety support 5, thereby playing a role in safety protection.

[0030] See Figure 10-11 As shown, when using this utility model in specific operation, a safety protection device for the maintenance of the roller system of a plate straightening machine is implemented according to the following detailed steps: Before the maintenance begins, place the four safety supports 5 into the four corresponding circular grooves 00211 of the lower roller system 002.

[0031] The support frame 1 with the V-shaped bracket 2 is placed on the roller system, aligning the V-shaped bracket 2 with the working roller 003 of the upper roller system 001. The lifting support frame 1 is placed into the base 3 along the C-shaped groove of the support frame 1, aligning the arc groove 302 below it with the working roller 003 of the lower roller system 002. Pads 4 are installed in the trapezoidal grooves 303 at both ends of the base 3 and placed on the front and rear guard plates of the lower roller box 0021 of the lower roller system 002 to form a support. One set of this device can be placed at each end below the working roller 003 of the upper roller system 001 to form a stable preventive support and provide safety protection.

[0032] After the maintenance is completed, remove the pad 4, base 3, support frame 1 with V-shaped bracket 2 in sequence, and remove the safety support 5 to complete the use.
