Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting equipment technology, and more specifically, to a rapid hoisting device for the wheels and support rollers of an annular cooling machine. Background Technology
[0002] The sintered cake is discharged into a water-cooled single-roll crusher via the tail feed chute and crushed to less than 150mm. The crushed hot sintered ore then enters an annular cooler for cooling. The cooled ore is transported away via a plate feeder, belt conveyor system, and other equipment. The cooling air for the annular cooler is supplied by four fans (three in operation and one on standby). The rotation of the annular cooler is driven by two sets of friction wheels, one on the north and one on the south, which rotate the friction plates. The friction plates are 30mm thick and 350mm wide. The annular cooler operates in a clean production environment, with a perimeter wall approximately 10 meters high. Only two maintenance workstations at fans 3 and 4 allow for crane installation and hoisting operations. No crane can be set up for hoisting operations from the unloading port of the annular cooler to the No. 2 fan section. When it is impossible to set up a crane to replace the wheels of the annular cooler trolley (weighing about 150kg), the work is carried out by manual dragging, which is very strenuous. According to GB12330-90 "Limits of Weight for Physical Handling", the limit for a man to carry a single load is ≤15kg, which seriously violates the safety management regulations. The weight of the modified annular cooler support roller is about 300kg, which is almost impossible to carry by manual labor. Utility Model Content

[0013] Furthermore, a reinforcing plate is welded to the bottom of the C-shaped frame, and the reinforcing plate has a hook-up hole, which serves as the hook-up point for the hoist used to transport and lift wheels or support rollers.
[0014] Furthermore, a reinforcing rib is welded to each of the two sides of the upper panel of the C-shaped frame to improve the strength of the upper panel.
[0015] Furthermore, the clamping universal ball and the boom support universal ball are respectively fixedly installed on the inner side of the C-shaped frame and the bottom of the boom by universal ball fixing screws; the clamping universal ball and the boom support universal ball located on the upper panel and lower panel of the C-shaped frame are of model SP25-FL, and the clamping universal ball located on the side panel of the C-shaped frame is of model SP12-FL.
[0016] Furthermore, the quick clamp is fixedly installed on the lower panel of the U-shaped frame by bolts, and the quick clamp is a push-pull quick clamp of model 305C.
[0017] Furthermore, an L-shaped anti-deviation hook is rotatably mounted on the upper panel of the C-shaped frame near the opening of the C-shaped frame.
[0018] Furthermore, the lower panel and side panels of the shaped frame both have hollowed-out areas.
[0019] Furthermore, it also includes a support roller support fixture, which includes a hydraulic jack and a support rod fixedly installed on the base plate; a support screw is provided at the top of the support rod, and the support screw is threaded into a threaded hole opened along the axial direction of the support rod; the extension length of the support screw can be adjusted by rotation; and a nut for locking the extension length of the support screw is detachably installed on the support screw.

[0040] like Figure 1-7 As shown, this utility model conducts a detailed study on the function and structure of the sintering ring cooler, and provides a rapid reversing and hoisting device for the ring cooler wheels and support rollers without damaging the ring cooler frame structure, including a C-shaped frame 1 and a boom 2.
[0041] The boom 2 is located above the chamfered frame 1, and one end is installed in the middle of the upper panel of the chamfered frame 1 via the boom pivot 3;
[0042] The inner sides of the upper panel, lower panel and side panel of the C-shaped frame 1 are respectively equipped with clamping universal balls 4; the bottom of the boom 2 is equipped with a boom support universal ball 6 located between the boom 2 and the upper panel of the C-shaped frame 1.
[0043] Two quick clamps 5 are fixedly installed on both sides of the lower panel of the C-shaped frame 1.
[0044] Furthermore, the distance between the clamping universal balls 4 on the upper and lower panels of the C-shaped frame 1 is matched with the thickness of the friction plate of the annular cooler. When the friction plate of the annular cooler is installed in the C-shaped frame 1, the clamping universal balls 4 on the upper and lower panels of the C-shaped frame 1 are pressed and contacted with the upper and lower surfaces of the friction plate, respectively.
[0045] Furthermore, after the ring cooler friction plate is installed in the C-shaped frame 1, the quick clamp adjustment screw 8 of the quick clamp 5 is pressed against the lower surface of the friction plate by adjusting the handle of the quick clamp 5, thereby locking the installation position of the device on the friction plate.
[0046] Furthermore, four clamping universal balls 4 are respectively installed on the inner sides of the upper and lower panels of the C-shaped frame 1; two clamping universal balls 4 are installed on the inner sides of the side panels of the C-shaped frame 1.
[0047] Furthermore, the steel rope used when installing the hoisting wheels or support rollers can be wound and installed on the boom 2; the end of the boom 2 without the boom shaft 3 is welded with a steel plate wider than the boom 2, which is used to strengthen the structural strength of the boom 2 and to prevent the steel rope from slipping off.
[0048] Furthermore, the C-shaped frame 1 is made by cutting and welding 8mm thick steel plate; the boom 2 is made by cutting and welding 30mm angle steel, and after the manufacturing is completed, it is ground smooth with a grinding wheel.
[0049] Furthermore, the boom shaft 3 adopts an existing handcart shaft, or the boom shaft 3 includes a central column and a bearing sleeved on the central column. The central column is fixedly installed on the middle of the upper surface of the top plate of the U-shaped frame 1, the inner ring of the bearing is fixedly installed on the central column, and one end of the boom 2 is fixedly installed on the outer ring of the bearing, thereby enabling the boom 2 to rotate. The boom support universal ball 6 is used to provide support when the boom 2 rotates, and to enable the boom 2 to rotate more smoothly.
[0050] Furthermore, a reinforcing plate is welded to the bottom of the C-shaped frame 1, and the reinforcing plate has a hanging hole as a hanging point for the hoist used to transport and lift wheels or support rollers.
[0051] Furthermore, a reinforcing rib 18 is welded to each of the two sides of the upper panel of the C-shaped frame 1 to improve the strength of the upper panel.
[0052] Furthermore, the clamping universal ball 4 and the boom support universal ball 6 are respectively fixedly installed on the inner side of the C-shaped frame 1 and the bottom of the boom 2 by universal ball fixing screws 7; the clamping universal ball 4 and the boom support universal ball 6 located on the upper and lower panels of the C-shaped frame 1 are of model SP25-FL, and the clamping universal ball 4 located on the side panel of the C-shaped frame 1 is of model SP12-FL; the permissible load of a single SP25-FL universal ball is 200kg. In this application, four identical universal balls are installed on the upper and lower panels of the C-shaped frame 1 respectively. According to the requirement that "the load they bear is less than 80% of their rated load", calculated at 75%, the theoretical maximum load is 200kg×4×75%=600kg≥300kg, which can fully meet the needs of hoisting the wheels and support rollers of the ring cooler.
[0053] Furthermore, the quick clamp 5 is fixedly installed on the lower panel of the U-shaped frame 1 by bolts, and the quick clamp 5 is a push-pull quick clamp of model 305C.
[0054] Furthermore, an L-shaped anti-deviation hook 9 is rotatably mounted on one end of the upper panel of the C-shaped frame 1 near the opening of the C-shaped frame 1. When the device is installed on the friction plate of the ring cooler, the anti-deviation hook 9 can be rotated so that the front end of the anti-deviation hook 9 is locked onto the protrusion on the upper surface of the friction plate, preventing the device from slipping out or shifting during operation. A mounting plate is welded to the upper surface of the upper plate of the C-shaped frame 1, and the anti-deviation hook 9 is rotatably mounted on the mounting plate via a pin.
[0055] Furthermore, to reduce the weight of the overall device, while ensuring the structural strength of the device, the lower panel and side panels of the C-shaped frame 1 are hollowed out: both the lower panel and side panels of the C-shaped frame 1 have hollowed-out areas 12; preferably, the lower panel of the C-shaped frame 1 has circular hollowed-out areas in the middle and at the four top corners; the side panels of the C-shaped frame 1 have rectangular hollowed-out areas, and the four corners of the rectangular hollowed-out areas are chamfered.
[0056] Furthermore, it also includes a support roller support fixture; when using the aforementioned device to move and lift the support rollers of the annular cooler, the support roller support fixture is used to lift and support the support rollers, such as... Figure 8As shown, the support roller support fixture includes a hydraulic jack 14 and a support rod 15 fixedly installed on the base plate 13. A support screw 16 is provided on the top of the support rod 15. The support screw 16 is threaded into a threaded hole opened along the axial direction of the support rod 15. The extension length of the support screw 16 can be adjusted by rotation. A nut 17 for locking the extension length of the support screw 16 is detachably installed on the support screw 16. When the support roller is lifted and supported by the support roller support fixture, the hydraulic jack 14 is used to lift the support roller. By adjusting the extension length of the support screw 16, the support screw 16 can support the support roller, which plays a role in providing hard protective support for the lifting of the hydraulic jack 14.
[0057] Furthermore, the support screw 16 adopts an M36 screw and The thick tubing is cut to a length of 250mm and welded together; the base plate 13 is made of a 30mm thick steel plate cut to a length and width of 400mm × 120mm; two hydraulic jacks 14 are installed on the base plate 13.
[0058] The rapid reversing and hoisting device for the ring cooler wheels and support rollers described in this utility model can slide and fix with the friction plates of the sintered ring cooler, so as to realize the rapid and safe reversing, hoisting and replacement of the ring cooler support wheels or wheels.
[0059] When using the device described in this utility model to reverse and lift the wheels and support rollers of the annular cooler:
[0060] The device is mounted on the friction plate, and the friction plate extends into the C-shaped frame 1 from the side opening of the C-shaped frame 1. The clamping universal ball 4 installed on the inner side of the upper panel, lower panel and side panel of the C-shaped frame 1 serves as the clamping contact point between the device and the friction plate. The device can be rotated on the friction plate at any time through the universal ball.
[0061] During operation, the wheels or support rollers are suspended below the device by steel ropes wound around the boom 2. One person can easily push the device from the outside forward at a 45° angle to the inside to slide it, thus easily moving the wheels and support rollers in the 360° direction of the annular cooler.
[0062] To improve the stability of the device during hoisting operations, when it is necessary to lock the position of the device on the friction plate, the handle of the quick clamp 5 can be adjusted so that the quick clamp adjusting screw 8 clamps the friction plate, thereby locking the installation position of the device and ensuring that the device does not slide arbitrarily.
[0063] Using the device described in this application, the hoist can be attached to the reinforcing plate at the bottom of the C-shaped frame 1, eliminating the need to cut holes in the stiffening plate of the trolley rails with an oxy-fuel cutter to install the hoist. This prevents the hoist attachment point from breaking due to the brittleness of the stiffening plate material.
[0064] The device described in this utility model is used for replacing wheels of annular cooling machines: steel cables can be directly attached to the boom, eliminating the need for setting up oxy-acetylene welding equipment, thus completing the replacement operation and saving time on setting up the welding equipment; when replacing multiple wheels, it can be done without rotating the machine for adjustment.
[0065] The device described in this utility model is used for replacing the support rollers of the annular cooler. The support rollers are heavier than wheels, and the device achieves a technological breakthrough by using friction plates to move the support rollers. It also eliminates the need to drill holes in the trolley sideboard to install a hand-operated hoist, reducing damage to the strength of the trolley sideboard. When replacing or repairing the support rollers of the annular cooler using the device described in this utility model, a support roller support fixture is required to provide rigid protective support for the hydraulic jacks.

[0067] Based on the above technical solution, the types and quantities of materials used in the device described in this embodiment are shown in the table below:

[0069] The device described in this embodiment was applied to the handling and hoisting of the wheels and support rollers of the ring cooler at Panzhihua Iron and Steel Group Xichang Steel & Vanadium Co., Ltd. Practice has proven that the device is lightweight, easy to operate, and allows for very quick handling and hoisting. It also reduces damage to the trolley sideboards and grating plates, making it economical, practical, safe, and reliable. It has significant potential for widespread application, and the benefits are as follows:
[0070] (1) Labor efficiency:
[0071] Before improvement: The lifespan of the wheels on the series of ring-cooled machine trolleys is 2 years, with 64 wheels per circumference. There are only two lifting positions. Assuming that half (32 wheels) cannot be lifted, 16 wheels need to be replaced annually under normal circumstances. The maintenance worker cost is 59.88 yuan / hour. The annual savings in maintenance manpower hours are:
[0072] S1 = 4 × (4-2) × 16 × 59.88 yuan / hour = 7,700 yuan;
[0073] The second-series ring cooler support rollers have achieved a breakthrough "from nothing to something" in locations where cranes cannot lift them, meaning that maintenance work can be carried out without violating regulations.
[0074] (2) Production efficiency:
[0075] (Total maintenance cost under the pre-implementation maintenance model - Total maintenance cost under the post-implementation maintenance model) × Technology contribution - R&D investment, according to the formula: Be=(Y1i–Yoi)×Ai×Gi×Ci-Bi
[0076] Be - Benefits of technological innovation, unit: RMB 10,000;
[0077] The output of Y1i-sintered ore is 500 tons / hour, and the total cost under the pre-maintenance mode is 500×4×4×16=128000;
[0078] The total cost under the Yoi-implementation post-maintenance mode is 500×4×2×16=64000;
[0079] Ai - Marginal profit of sintered ore, unit: RMB 10,000 / t; 0.0127;
[0080] Gi - the contribution coefficient of process technology, taken as 0.5;
[0081] Ci - Effective operating rate, 0.5;
[0082] Research and development investment in Bi-process technology research project: 0.5 million yuan;
[0083] Be = (128000 - 64000) × 0.0127 × 0.5 × 0.5 - 0.5 = 202.7 million yuan;
[0084] Total annual profit: S = 202.7 + 0.77 = 203.47 million yuan.
[0085] The rapid transfer and hoisting device described in this application solves the problem of hoisting the wheels or support rollers of the annular cooler when they are inaccessible by cranes. It also allows maintenance work to be carried out without violating safety management regulations, achieving a new breakthrough from "nothing to something". At the same time, it saves maintenance time, reduces unit downtime, and makes a positive contribution to increasing sinter production. The rapid transfer and hoisting device described in this application is lightweight, easy to operate, and allows for very quick transfer and hoisting. It also reduces damage to the trolley sideboards and grating plates, making it economical, practical, safe, and reliable.
[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
