Description

Technical Field

[0001] This utility model relates to the field of maintenance technology for cold and hot rolling production units, and specifically to an HGC hydraulic cylinder placement rack. Background Technology

[0002] In cold and hot rolling mills, the rolling force or roll gap is typically controlled by a bottom-mounted HGC (Hydraulic Gap Control) cylinder, abbreviated as HGC. During operation, the HGC cylinder is installed at the bottom center of the leveling mill frame, positioned on both the drive and operating sides. The lower support roll changing tracks are located on either side of the HGC cylinder. The HGC cylinder adjusts the rolling force or roll gap of the leveling mill by lifting the lower support rolls. Because the HGC cylinder operates under high load for extended periods in harsh environments, it requires regular maintenance or replacement.

[0003] The HGC hydraulic cylinder is cylindrical, with a protruding mounting and positioning ring at the center of its bottom, and a sensor cable extending from the middle of the ring.

[0004] The existing technology lacks a device that can support HGC hydraulic cylinders. During the periodic replacement process, operators must use a crane to inspect HGC hydraulic cylinders. It is extremely unsafe for people to operate under the load, which does not comply with safety regulations. However, if the HGC hydraulic cylinder is placed on a platform, it is difficult to inspect and repair the bottom of the cylinder. Furthermore, the weight of the HGC hydraulic cylinder itself can easily damage the sensor cables extending from its bottom. Utility Model Content

[0005] The purpose of this application is to solve the problem that the sensor cable at the bottom of the HGC hydraulic cylinder is easily damaged by crushing in the prior art, making it difficult for construction personnel to inspect and repair the bottom of the HGC hydraulic cylinder. Therefore, this utility model provides an HGC hydraulic cylinder placement rack, which supports the HGC hydraulic cylinder through a support frame, and the sensor cable is located through the inner ring to prevent the cable from being crushed during operation. With the support of the support legs, construction personnel can enter the bottom of the placement rack to inspect and repair the bottom of the HGC hydraulic cylinder.

[0006] To achieve the above objectives, this utility model provides an HGC hydraulic cylinder placement rack, including a support platform, the bottom of which is supported by support legs;

[0007] The support platform includes an outer ring and an inner ring. The outer ring is a square frame formed by multiple support rods connected end to end. The inner ring is located inside the outer ring and is formed by long rods and short rods. Two long rods are arranged parallel to each other on the support rods, and two short rods are arranged parallel to each other on the long rods.

[0008] The HGC hydraulic cylinder is placed on the support platform, and the convex ring at the bottom of the HGC hydraulic cylinder is placed inside the inner ring.

[0009] Using the above technical solution, the bottom of the entire HGC hydraulic cylinder is supported by both the outer and inner rings. The convex ring at the center of the HGC hydraulic cylinder is housed within the inner ring, protecting the sensor cable inside the convex ring and preventing it from being damaged. Furthermore, supported by the support legs, the HGC hydraulic cylinder is at a certain height above the ground, allowing maintenance personnel to access and repair the sensors at the bottom of the HGC hydraulic cylinder from below. Because the HGC hydraulic cylinder is stably supported by the entire support frame, maintenance personnel are safer during the repair process.

[0010] In some embodiments, the upper part of the support platform is provided with four lifting points, which are respectively located at the corner positions of the outer ring.

[0011] By adopting the above technical solution, the entire HGC hydraulic cylinder support frame can be lifted through the lifting points, making it easier to move the entire HGC hydraulic cylinder support frame.

[0012] In some embodiments, the support legs are four in number, each supporting a corner of the outer ring.

[0013] By adopting the above technical solution, the support legs are supported at the corner positions of the outer ring, which makes the entire structure more stable.

[0014] In some embodiments, the bottom of the support leg is provided with an iron plate.

[0015] By adopting the above technical solution, the iron plate increases the contact area between the bottom of the support leg and the ground, thereby increasing the stability of the support leg.

[0016] In some embodiments, the support rod, long rod, short rod, and support leg are all H-beams.

[0017] The above technical solution uses H-beams, which are readily available, have high overall strength, and provide more stable support.

[0018] In some embodiments, the upper surface of the support platform is covered with a rubber pad.

[0019] By adopting the above technical solution, the bottom of the HGC hydraulic cylinder can be protected by the rubber pad, preventing damage to the bottom of the HGC hydraulic cylinder.

[0020] In some embodiments, a tie rod is provided laterally on the lower side of the support leg.

[0021] By adopting the above technical solution, the stability of the overall structure is further increased by using lateral tie rods.

[0022] In summary, this application proposes a novel HGC hydraulic cylinder support frame, on which the HGC hydraulic cylinder can be placed for maintenance and inspection. An operator can replace the HGC hydraulic cylinder's sensor via the inner ring from the bottom of the support platform. This solves the problem of easily damaged HGC hydraulic cylinder sensor cables in conventional solutions.

[0023] On the other hand, the inner ring consists of a long rod and a short rod, the positions of which can be set as needed according to the position and size of the convex ring at the bottom of the HGC hydraulic cylinder. Attached Figure Description

[0033] Example

[0034] Please see Figure 1-3 This embodiment provides an HGC hydraulic cylinder placement rack, including a support platform, the bottom of which is supported by support legs 1;

[0035] The support platform includes an outer ring 2 and an inner ring 3. The outer ring 2 is a square frame formed by four identical support rods 21 connected end to end. The inner ring 3 is located inside the outer ring 2 and is formed by long rods 31 and short rods 32. The two long rods 31 are arranged parallel to each other on the support rods 21, and the two short rods 32 are arranged parallel to each other on the long rods 31.

[0036] The HGC hydraulic cylinder 4 is placed on the support platform, and the convex ring 41 at the bottom of the HGC hydraulic cylinder 4 is placed inside the inner ring 3.

[0037] It should be noted that the bottom of the HGC hydraulic cylinder 4 has a convex ring 41 for mounting and positioning. At the center of the convex ring 41, a sensor cable extends from inside the HGC hydraulic cylinder 4. The sensor cable is a key point for the maintenance and inspection of the HGC hydraulic cylinder 4.

[0038] In existing technology, there is a lack of support devices for the HGC hydraulic cylinder 4. Generally, when replacing the HGC hydraulic cylinder 4, it is lifted by a forming machine for inspection and maintenance. However, this method poses significant safety hazards. In some cases, construction workers need to lower the HGC hydraulic cylinder 4, but due to the lack of a placement platform, it can only be placed in a temporary location. Since the convex ring 41 protrudes from the lower surface of the HGC hydraulic cylinder 4, and the sensor cable also extends from the convex ring 41, the sensor cable is pressed under the convex ring 41 during placement. The weight of the HGC hydraulic cylinder 4 itself can easily damage the sensor cable at the bottom of the HGC hydraulic cylinder 4.

[0039] This embodiment provides a support frame. The structure of the support frame is designed according to the structure of the HGC hydraulic cylinder 4. The inner ring 3 can accommodate the convex ring 41 at the bottom of the HGC hydraulic cylinder 4 and the sensor cable protruding from the inside of the convex ring 41, preventing the sensor cable from being squeezed. The HGC hydraulic cylinder 4 is supported by the support leg 1. The bottom of the support frame has space for replacing the sensor cable, and the construction personnel can inspect and repair the sensor cable at the bottom of the HGC hydraulic cylinder 4.

[0040] Specifically, the outer ring 2 is sized to match the HGC hydraulic cylinder 4, allowing the HGC hydraulic cylinder 4 to be placed on its upper surface. The inner ring 3 is located at the center of the outer ring 2, and its size matches the size of the convex ring 41 at the bottom of the HGC hydraulic cylinder 4.

[0041] Specifically, there are four support rods 21, each supporting one of the corner points of the outer ring 2. The height of the support legs 1 should be sufficient for construction personnel to access the bottom for inspection and maintenance. Specifically, four tie rods 8 are horizontally installed on the underside of the support legs 1. These tie rods 8 are positioned between two support legs 1, and an iron plate 6 is installed at the contact point between the support legs 1 and the ground, increasing the contact area between the support legs 1 and the ground.

[0042] Specifically, the support rod 21, long rod 31, short rod 32, tie rod 8, and support leg 1 are all H-beams. Preferably, the H-beams are 100*100mm in size, and the iron plate 6 is 20mm thick.

[0043] Specifically, the support rods 21 are fixed together by welding, the long rod 31 and the short rod 32 are also fixed together by welding, the support leg 1 is fixed to the support rod 21 by welding, the iron plate 6 at the bottom of the support leg 1 is welded to the support leg 1, and the pull rod 8 is also welded to the support leg 1.

[0044] Specifically, four lifting points 5 are provided on the upper part of the support platform, respectively located at the corner positions of the outer ring 2. When the entire support platform is moved, the lifting ropes can be connected to the lifting points 5, and the entire HGC hydraulic cylinder 4 placement frame can be lifted by a crane.

[0045] In addition, to protect the lower surface of the HGC hydraulic cylinder 4, a rubber pad 7 is provided at the contact position between the HGC hydraulic cylinder 4 and the placement platform. The rubber pad 7 can play a buffering role to prevent the bottom of the HGC hydraulic cylinder 4 from being damaged during placement. The rubber pad 7 can also play a protective role to prevent the bottom of the HGC hydraulic cylinder 4 from being worn.
