Description

Technical Field

[0001] The utility model belongs to the field of steel rolling production equipment and relates to a reel disassembly and assembly transfer device. Background Art

[0002] When the reel in the steel rolling production line has a fault such as component damage, different maintenance plans need to be adopted depending on the situation. If the parts to be maintained are easy to disassemble and install and take a short time, you can choose to shut down and perform maintenance in place; if the maintenance is difficult or the maintenance part is located inside the machine body and takes a long time, you need to replace the reel with a new spare part to maintain normal production, and disassemble the faulty reel for offline maintenance.

[0003] There are two common ways to disassemble the reel, unpacking and quick disassembly. Conventional reels can only be disassembled by unpacking, that is, the reducer box of the uncoiler or coiler is opened to disassemble the reel as a whole; quick-disassembly reels can be disassembled by unpacking or quick disassembly. The principle of quick disassembly is to utilize the matching structure of the tapered shaft and tapered sleeve inside the reel. Only a part of the structure at the rear end of the reel needs to be disassembled, and force can be applied from the transmission end to push the main body of the reel out from the operating end. The quick disassembly method does not require unpacking, and both disassembly and reinstallation are more time-saving and labor-saving.

[0004] After the reel is disassembled, when there is equipment or steel structure blocking the top of the reel and conventional lifting is impossible, the existing method often uses a C-shaped hoist to lift it out or a steel coil trolley to lift it out. In order to avoid the upper structure while ensuring sufficient mechanical strength, the C-shaped hoist is often relatively large, and its operability and economy are not good. In comparison, the method of lifting the steel coil trolley is more widely used, but this method also has some disadvantages. For example, the saddle area above the trolley is small, the operation and standing space of maintenance personnel are limited, and the saddle of the trolley is surrounded by a foundation pit, which makes the operation unsafe. During the process of lifting the reel out, the reel is prone to shaking and there is a risk of falling. Utility Model Content

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0035] like Figure 1 , 2 As shown, the utility model discloses a reel disassembly, assembly and transfer device (hereinafter referred to as the device) which mainly includes a fastening base assembly 1, a lifting transmission device 2 and a lifting seat assembly 3, which are three main components.

[0036] The function of the fastening base assembly 1 is to connect with the steel coil car lifting structure 4 at the bottom to achieve fastening with the steel coil car, and to install the lifting transmission device 2 at the top to provide an operating platform and protection for the operator. The fastening studs 13 and the top bolts 14 are bolts arranged in perpendicular directions to position the device in two directions, wherein the fastening studs 13 penetrate into the steel coil car lifting structure 4 for fastening to ensure the stability of the installation. Figure 6 As shown, a patterned steel plate that can increase the friction coefficient is laid on the top of the operating platform 15, and guardrails 11 are arranged around the platform. The guardrails should be set on the basis of avoiding the front and rear end structures of the reel, and the entrance and exit for operators should be reserved. Safety chains or safety doors should be set at the entrance and exit. Lifting ears 12 are set at appropriate positions on the operating platform 15 for lifting the device. The guide shaft 17 is installed on the fastening base assembly 1 with threaded fasteners. The base of the spiral elevator 21 is installed on the fastening base assembly 1 with threaded fasteners. A V-block 16 is arranged below the fastening base assembly 1, which is used to match the shape of the V-shaped saddle above the steel coil car lifting structure 4. The V-shaped surface has automatic centering and positioning functions, and can fit well for the purpose of transmitting force.

[0037] The lifting transmission device 2 is manually operated, and the power output by the operator is driven by the hand wheel 22 on one side to drive the screw elevator 21 on one side, and the motion is transmitted to the screw elevator 21 on the other side through the elastic coupling 23, so that the lifting seat assembly 3 connected to the screw elevator 21 rises or falls. The hand wheel 22 is installed at one end of the worm shaft of the screw elevator 21, and the coupling 23 connects one end of the worm shaft of the two screw elevators 21, which plays a role of synchronous transmission. The screw of the screw elevator 21 is connected to the bottom of the lifting frame 39 by a threaded fastener. When the reel 5 needs to be tilted at a certain angle, the lifting frame 39 can be set to a split type, and the elastic coupling 23 can be quickly disengaged, which can facilitate the height difference between the two parts of the lifting frame 39. When the lifting frame 39 is an integrated type, the screw elevator 21 can be a basic type and an anti-transformation type. When the lifting frame 39 is a split type, the screw elevator 21 should be an anti-transformation type.

[0038] The lifting seat assembly 3 is mainly responsible for supporting the reel. It is connected to the spiral lift 21 at the bottom. Four guide sleeves 38 are arranged at the bottom to cooperate with the guide shaft 17 to ensure the smooth operation of the lifting seat assembly 3. The guide sleeve 38 is a lubricating sleeve, which can be made of self-lubricating material or processed with a lubricating oil groove, and adopts the lubrication method of oil cup filling. The guide sleeve 38 is installed in the sleeve structure below the lifting frame 39, and cooperates with the guide shaft 17 to achieve guidance, ensuring the smooth lifting of the lifting frame 39. Figure 7 As shown, the protective clamp 33 swings around the rotating shaft 37 and then stops at the limit block 36. The limit principle is to use the arc surface on the protective clamp 33 and the plane tangent to define the running track of the protective clamp 33. Figure 2 , Figure 4 As shown, the cushion block 31 is located at the no-load position and the loaded position respectively. The switching between the two different positions is achieved by sliding the cushion block 31 in the T-shaped slide groove. A baffle is provided at one end of the cushion block 31 to prevent it from falling during use. Similarly, Figure 3 As shown, the latch 32 is also installed in a closed latch sleeve to ensure that the latch 32 will not fall off during the operation and use of the device, thereby preventing danger.

[0039] The working process of this device is as follows:

[0040] The steel coil car is located in the waiting position outside the coil area, and the device is installed on the steel coil car lifting structure 4. Figure 4 As shown, the pad 31 is located in the no-load position, that is, close to one end of the center line of the reel. At this time, one end of the protective clamp 33 is placed on the pad 31, so that the protective clamp 33 swings around the rotating shaft 37 to form an angle α, and the hand wheel 22 is adjusted to form a gap h between the lining plate 34 and the theoretical position of the reel. It should be noted that the gap here does not have to be completely equal and accurate. The existence of the gap value is to ensure that no interference friction occurs when the steel coil trolley drives the device close to the reel. In addition, the protective clamp 33 is not opened to the position of the limit block 36 for opening and closing, in order to avoid unnecessary shaking or interference with surrounding structures during operation.

[0041] Slowly drive the coil trolley into the reel 5 area, and observe the gap value h at any time. If the gap is too small, adjust the hand wheel 22. Figure 1 As shown, move the device to the bottom of the reel, remove the expansion and contraction cylinder and other structures on the transmission side of the reel 5, and remove the reel 5 body from the operating side. Make sure that the center of gravity of the reel falls between the two protective clamps 33. This step is necessary to ensure that the reel 5 does not tip over during the operation of the steel coil trolley. Adjust the hand wheel 22 to make the upper lining plate 34 of the lifting frame 39 contact the fan-shaped plate on the lower surface of the reel to support the reel 5. Figure 2 As shown, the movable pad 31 is located at the rear end position away from the center line of the reel, that is, the load position, and the protective clamp 33 is buckled onto the fan-shaped plate on the upper surface of the reel 5, as shown in FIG. Figure 3 As shown, the latch pin 32 is inserted into the latch pin hole of the protective clamp 33 from both sides, and the clamping operation of the reel on the device is completed.

[0042] Drive the coil trolley out of the reel 5 area to the set lifting position, and pull out the latch 32. Figure 5As shown, flip open the protective clamp 33 to the position of the limit block 36, use a crane to lift the old reel away, and load the new reel, flip close the protective clamp 33, insert the latch 32, drive the steel coil trolley into the reel area, pull out the latch 32, flip open the protective clamp 33 to a certain angle α, pad the pad 31, load the new reel into the coiler (uncoiler), and drive the steel coil trolley out of the reel area. At this point, the device completes a reel disassembly, assembly and transfer process.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
