In the case of long-term use of the grate cooler, the axle pins will wear and need to be replaced in time.

[0003] The existing maintenance lifting device for a grate cooler uses hydraulic equipment. By repeatedly pushing and pressing down, the hydraulic push rod is controlled to push. When installing, in order to avoid insufficient height of the lifting device, wooden blocks need to be placed at the bottom of the equipment to raise it. However, when lifting the height in this way, it is easy to cause the problem of unstable fixation during the initial push. Content of the Utility Model

[0004] In order to solve the problem in the prior art that in order to avoid insufficient height of the lifting device, wooden blocks need to be placed at the bottom of the equipment to raise it, but when lifting the height in this way, it is easy to cause the problem of unstable fixation during the initial push, the utility model provides a maintenance lifting device for a grate cooler. By pushing the lifting fitting plate with a push rod to make the fitting rubber pad fit with the position to be lifted, and then making the spring push the push rod inside the telescopic groove opened in the hydraulic rod. If the height is too high, the lifting fitting plate can drive the push rod to press down, and the anti - detachment block slides along the outside of the positioning block, thereby determining the height of the push rod. Insert the positioning rod into the fixing groove along the fixing hole to fix the push rod, achieving the effect of positioning the height, solving the problem that in the past, wooden blocks needed to be placed at the bottom of the equipment to raise it, but when lifting the height in this way, it was easy to cause the problem of unstable fixation during the initial push, and improving the stability of height adjustment.

[0022] The following will describe the present utility model in detail in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present utility model.

[0023] As Figures 1 - 5 shown, the present utility model aims to provide a maintenance and lifting device for a grate cooler to solve the problem that in order to avoid insufficient height of the lifting device, wooden blocks need to be placed at the bottom of the equipment for elevation, but when lifting the height in this way, it is easy to cause unstable fixation during the initial lifting. According to the above functions, the whole device includes a telescopic oil cylinder 1, a hydraulic rod 2 is slidably connected inside the telescopic oil cylinder 1, a telescopic groove 3 is opened at the top of the hydraulic rod 2, a spring 4 is fixedly connected inside the telescopic groove 3, a push plate 6 is fixedly connected to the top of the spring 4, and a push rod 5 is fixedly connected inside the push plate 6;

[0024] An anti - detachment block 14 is fixedly connected to the outside of the push rod 5, the anti - detachment block 14 is arranged in a right - angled triangle shape, the top of the anti - detachment block 14 abuts against a positioning block 9, the positioning block 9 is slidably connected inside the hydraulic rod 2, and a rotating assembly is arranged on the side of the hydraulic rod 2 away from the anti - detachment block 14.

[0025] The telescopic oil cylinder 1 controls the hydraulic rod 2 inside to rise, and then the spring 4 pushes the push rod 5 inside the telescopic groove 3 opened in the hydraulic rod 2. When the height is too high, the lifting and fitting plate 15 can drive the push rod 5 to press down, and the anti - detachment block 14 slides along the outside of the positioning block 9, thereby determining the height of the push rod 5, achieving the effect of preliminary height positioning. The opening and closing of the positioning block 9 can be controlled by the rotating assembly, solving the problem of selecting sleepers to elevate the height of the lifting equipment in the past and improving the convenience of preliminary adjustment.

[0026] As Figures 2 - 4As shown, the rotating assembly includes a rotating shaft 8, which is rotatably connected to one end of the positioning block 9 away from the anti - detachment block 14. On the side of the rotating shaft 8 away from the positioning block 9, there is a fixed connection with a mounting block 7, and the mounting block 7 is fixedly connected to the outside of the hydraulic rod 2. On the side of the push rod 5 away from the anti - detachment block 14, there is a fixed groove 11. On the outside of the hydraulic rod 2 near the fixed groove 11, there is a fixed hole 10. Inside the fixed hole 10, there is a sliding connection with a positioning rod 12. One end of the positioning rod 12 away from the fixed groove 11 is fixedly connected to a taking - and - fitting plate 13. The taking - and - fitting plate 13 is arc - shaped and abuts against the outside of the hydraulic rod 2.

[0027] The rotating shaft 8 is fixed by using the mounting block 7, and then the positioning block 9 is controlled by the rotating shaft 8 to open and close. At this time, the positioning block 9 can abut against the top of the anti - detachment block 14 to prevent the problem of excessive driving force of the spring 4. After positioning, the positioning rod 12 can be inserted into the fixed groove 11 along the fixed hole 10 to fix the push rod 5, solving the problem that the inclined plane of the anti - detachment block 14 is prone to slide along the positioning block 9 during pushing due to the single positioning of the anti - detachment block 14, improving the stability of the adjusted height, and increasing the further positioning effect and fixing effect of the push rod 5.

[0028] As Figures 2 - 5 shown, there are multiple groups of anti - detachment blocks 14 and fixed grooves 11 arranged in a linear array on the outside of the push rod 5. The fixed grooves 11 and the anti - detachment blocks 14 are correspondingly arranged. On the top of the push rod 5, there is a fitting assembly. The fitting assembly includes a lifting - and - fitting plate 15, which is fixedly connected to the top of the push rod 5. On the top of the lifting - and - fitting plate 15, there is a fixedly connected fitting rubber pad 16. On the outside of the telescopic oil cylinder 1, there is a control assembly. The control assembly includes a base 19, which is fixedly connected to the bottom of the telescopic oil cylinder 1. On the top of the base 19, there is a fixedly connected adjusting rod 17. The adjusting rod 17 is arranged on one side of the telescopic oil cylinder 1, and on the top of the adjusting rod 17, there is a fixedly connected insertion sleeve 18.

[0029] When positioning the push rod 5 at different heights, the multiple - group structures of the anti - detachment blocks 14 and the fixed grooves 11 can better perform positioning at different heights. The lifting - and - fitting plate 15 can ensure that the fitting rubber pad 16 fits with the lifting position to be installed, so as to better perform support and lifting. When controlling the hydraulic rod 2 to lift and lower, the insertion sleeve 18 can control the adjusting rod 17 to perform reciprocating motions of raising and lowering. At this time, the adjusting rod 17 can control the telescopic oil cylinder 1 to control the hydraulic rod 2 to lift and lower along the base 19, achieving a lifting effect, solving the problem that the contact area between the single telescopic oil cylinder 1 for lifting and the ground is small, resulting in uneven force, and improving the stability of lifting.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each example can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
