Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of annular coolers in the metallurgical industry, and specifically relates to a slide plate assembly trolley for annular coolers. Background Technology
[0002] Circular coolers are large-scale metallurgical equipment used in industrial production, widely applied in cement, metallurgy, drying, and solid waste treatment industries. Conventional circular cooler trolleys are integrally cast structures, large in size, and require large machining equipment for processing. If some grate bars are damaged, the entire trolley must be replaced. Replacement requires the use of large lifting tools to lift the entire trolley out, replace the shaft with the new trolley, and then use lifting tools to lift the trolley back in. This results in significant downtime for replacements, impacting production efficiency. Utility Model Content
[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a slide plate assembly trolley for an annular cooler. This invention can save the cost of replacing the entire trolley, reduce the time required for trolley repair, alleviate the labor intensity of personnel, and thus improve the operating rate of the annular cooler.
[0004] To achieve the above objectives, the present invention adopts the following technical solution.
[0005] This utility model provides a plate-mounted assembly trolley for an annular cooler, comprising a fan-shaped welded frame. The welded frame is divided into multiple partitions by radially arranged partition beams. The welded frame has shaft holes on both sides of one non-central partition, and multiple main shaft seats with through holes are arranged in this partition. The partition beams are provided with positioning holes that mate with the sides of the main shaft seats. The two ends of the partition beams are detachably connected to the welded frame. Multiple arc-shaped grate screen bars are detachably connected above the partition beams. All the grate screen bars are arranged radially along the welded frame and circumferentially. Multiple screen bar pressure plates are detachably connected above the grate screen bars, and the screen bar pressure plates are all detachably radially connected to the welded frame.
[0006] Furthermore, both ends of the partition beam have beam flanges, and the welded frame is provided with beam positioning holes corresponding to the beam flanges. The partition beam is made of a material with plastic deformation, and the partition beam is detachably connected to the welded frame by inserting the beam flanges into the beam positioning holes.
[0007] Furthermore, the partition beam has a pin hole on its flange extending outside the welded frame. By inserting a locking pin into the pin hole, the partition beam is fixed to the welded frame.
[0008] Furthermore, the upper end of the partition beam is provided with multiple upper positioning grooves, the same number as the grate screen bars. The grate screen bars are made of a material with plastic deformation. The grate screen bars are inserted vertically in an arc shape into the upper positioning grooves and are detachably connected to the partition beam. The grate screen bars are fixed by the elastic force of the grate screen bars and the limiting position of the upper positioning grooves.
[0009] Furthermore, all of the aforementioned upper positioning grooves are the same size.
[0010] Furthermore, the screen bar pressure plate has plate flanges at both ends, and the welding frame is provided with plate positioning holes corresponding to the plate flanges. The screen bar pressure plate is made of a material with plastic deformation. The screen bar pressure plate is detachably connected to the welding frame by inserting the plate flanges into the plate positioning holes.
[0011] Furthermore, the lower end of the screen bar pressure plate is provided with a plurality of lower positioning grooves, the same number as the number of the grate screen bars. The screen bar pressure plate presses against the grate screen bars through the lower positioning grooves, thereby locking the grate screen bars.
[0012] Furthermore, all of the lower positioning grooves are the same size.
[0013] The beneficial effects of this utility model.
[0014] This utility model uses an insert-type design for both the grate bars and partition beams. All positioning grooves on the partition beams are the same size, facilitating the machining of the grate bar end faces and easy replacement after damage. For replacement, open the grate bar pressure plate, insert the lifting tool into the gaps in the grate bars, and pull upwards to remove them. When installing the partition beams, apply external force to the flanges at both ends of the beam, ensuring a slight bend that allows the partition beam to enter the welded frame. This allows the flanges at both ends to precisely enter the beam positioning holes. The springback mechanism secures the partition beam in the beam positioning holes on the welded frame. Insert locking pins into the locking pin holes at both ends to complete the replacement. This design saves downtime for the annular cooler during maintenance, thereby improving the operating efficiency of the production line. Attached Figure Description

Detailed Implementation
[0023] As shown in the accompanying drawings, this embodiment provides a plate-mounted trolley for an annular cooler, including a fan-shaped welded frame 1. The welded frame 1 is divided into multiple partitions by a plurality of radially arranged partition beams 2. The welded frame 1 has shaft holes 3 on both sides of one of the non-central partitions, and a plurality of spindle seats 4 with through holes are provided in this partition. The shaft holes 3 and the through holes of the spindle seats 4 are used to pass through the spindles. The non-central setting is also a prior art, in order to facilitate the trolley's own weight to fall back and level after unloading.
[0024] The partition beam 2 is provided with positioning holes 5 that mate with the two sides of the main shaft seat 4. The main shaft seat 4 is detachably fixed to the partition beam 2 by inserting it into the positioning holes 5 on both sides.
[0025] The partition beam 2 has beam flanges 8 at both ends, and the welded frame 1 is provided with beam positioning holes 9 corresponding to the beam flanges 8. The partition beam 2 is made of a material with plastic deformation. The partition beam 2 is detachably connected to the welded frame 1 by inserting the beam flanges 8 into the beam positioning holes 9.
[0026] The partition beam 2 has a pin hole 10 on the beam flange 8 extending outside the welded frame 1. By inserting the locking pin 11 into the pin hole 10, the partition beam 2 is fixed to the welded frame 1.
[0027] Multiple arc-shaped grate bars 6 are detachably connected above the partition beam 2. All grate bars 6 are arranged radially along the welded frame 1 and circumferentially. The upper end of the partition beam 2 is provided with multiple upper positioning grooves 12, the same number as the grate bars 6. All upper positioning grooves 12 are the same size, which facilitates the machining of the end face of the grate bars 6 and replacement after damage. The grate bars 6 are made of a material with plastic deformation. The grate bars 6 are arc-shaped and vertically inserted into the upper positioning grooves 12 and detachably connected to the partition beam 2. The grate bars 6 are fixed by the elastic force of the grate bars 6 and the limiting position of the upper positioning grooves 12.
[0028] Multiple screen bar pressure plates 7 are detachably connected above the grate screen bars 6. The screen bar pressure plates 7 are all detachably radially arranged and connected to the welded frame 1. Each screen bar pressure plate 7 has a plate flange 13 at both ends. The welded frame 1 is provided with a plate positioning hole 14 corresponding to the plate flange 13. The screen bar pressure plates 7 are made of a material with plastic deformation. The screen bar pressure plates 7 are detachably connected to the welded frame 1 by inserting the plate flange 13 into the plate positioning hole 14.
[0029] The lower end of the screen bar pressure plate 7 is provided with multiple lower positioning grooves 15, which are the same number as the grate screen bars 6. All the lower positioning grooves 15 are the same size. The screen bar pressure plate 7 presses on the grate screen bars 6 through the lower positioning grooves 15, thereby locking the grate screen bars 6.
[0030] The usage method is as follows:
[0031] When the partition beam 2 is damaged during use, pull out the locking pin 11, use a jack to slightly bend the partition beam 2 so that the partition beam 2 comes out of the beam positioning hole 9; when installing the new partition beam 2, follow the reverse process, apply external force to the beam flanges 8 at both ends so that the partition beam 2 is slightly bent and can enter the welded frame 1, then press the partition beam 2 down so that the beam flanges 8 at both ends can just enter the beam positioning hole 9, insert the locking pin 11 into the pin hole 10 at both ends, and thus complete the replacement.
[0032] When the grate screen bar 6 is damaged during use, the screen bar pressure plate 7 can be opened and pulled out from the plate positioning hole 14. The lower positioning groove 15 will disengage the grate screen bar 6. The damaged grate screen bar 6 component can be pulled upwards. Under the action of tension, the grate screen bar 6 will be deformed into a "U" shape, and the grate screen bar 6 will then be disengaged from the upper positioning groove 12 of the partition beam 2. The damaged grate screen bar 6 can then be easily removed. When installing a new grate screen bar 6, first place the grate screen bar 6 into the upper positioning groove 12 of the partition beam 2, and then install the screen bar pressure plate 7. The lower positioning groove 15 of the screen bar pressure plate 7 will then lock the grate screen bar 6, thus completing the replacement.
