Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder maintenance devices, and in particular to an auxiliary device for the maintenance of a grate hydraulic cylinder. Background Technology

[0002] In municipal solid waste treatment, waste incineration plays a dominant role, and the grate system is the core component of a waste-to-energy plant. Its operational stability directly determines the residence time of waste in the furnace and the completeness of combustion. As the power equipment that drives the grate, the grate hydraulic cylinder operates in harsh environments such as high temperature and dust for a long time, which can easily lead to aging of seals, wear of piston rods, and blockage of oil circuits. Timely disassembly and maintenance are necessary; otherwise, the grate may malfunction.

[0003] Currently, the disassembly of grate hydraulic cylinders in existing technologies mainly relies on manual labor.

[0004] However, due to the large size and weight of the hydraulic cylinder, it often shakes during lifting and installation, making it difficult to align the spindle threads and hindering installation. At the same time, when it is necessary to disassemble the hydraulic cylinder, it needs to be rotated manually, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for the maintenance of a grate hydraulic cylinder, so as to alleviate the technical problems of shaking during installation and the need for manual rotation in the prior art.

[0006] This utility model provides an auxiliary device for the maintenance of a grate hydraulic cylinder, comprising: a base, lifting lugs, lifting holes, a hand chain hoist, a support column, and a rotating seat; two lifting lugs are vertically welded to both sides of the top surface of the base, and each lifting lug has a lifting hole on its surface, into which the hook of the hand chain hoist is inserted;

[0007] A support column is welded to the center of the top surface of the base. The support column is rotatably connected to the rotating seat. A hydraulic cylinder is placed inside the rotating seat to rotate the hydraulic cylinder along the central axis of the support column.

[0008] Furthermore, a connecting column is provided at the top of the support column, and a cylinder is provided at the bottom of the rotating seat. The cylinder is fitted outside the connecting column, so that the support column and the rotating seat are rotatably connected.

[0009] Furthermore, a first connecting hole is provided at the center of each support column, and a second connecting hole is provided at the center of the rotating seat, which is concentric with the first connecting hole. A positioning pin is inserted into the first connecting hole and the second connecting hole.

[0010] Furthermore, a rubber anti-slip layer is provided on the inner surface of the rotating seat.

[0011] Furthermore, the swivel seat is square in shape, with the length of any side of the swivel seat being 20cm to 30cm.

[0012] Furthermore, the diameter of the hanging device is 3cm to 5cm.

[0013] Furthermore, the base surface is also provided with fixing holes, and several fixing holes are spaced apart along the length of the base, for detachably fixing the auxiliary device to the external support by bolts.

[0014] Beneficial effects:

[0015] This utility model uses the lifting lugs on both sides of the base to cooperate with the hand chain hoist, which can conveniently realize the up and down movement of the equipment and hydraulic cylinder. The support column in the middle of the base is rotatably connected to the rotating seat, which can drive the hydraulic cylinder to rotate along the central axis of the support column. The combination of the two allows the hydraulic cylinder to be flexibly adjusted in height and easily rotated during maintenance, thereby effectively assisting the maintenance work of the hydraulic cylinder on site, reducing maintenance time, and improving maintenance efficiency.

[0016] Accordingly, this invention can reduce the working time of on-site personnel in high-temperature environments, thereby reducing the risk of safety production. Attached Figure Description

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Example 1

[0031] like Figure 1 , Figure 2 As shown, this utility model discloses an auxiliary device for the maintenance of a grate hydraulic cylinder, including: a base 1, a lifting lug 2, a lifting hole 3, a hand chain hoist 4, a support column 5, and a rotating seat 6;

[0032] Two lifting lugs 2 are vertically welded to the top surface of the base 1 on both sides. Each lifting lug 2 has a lifting hole 3 on its surface. The hook of the hand chain hoist 4 is hung into the lifting hole 3.

[0033] A support column 5 is welded to the center of the top surface of the base 1. The support column 5 is rotatably connected to the rotating seat 6. A hydraulic cylinder is placed inside the rotating seat 6 to rotate the hydraulic cylinder along the central axis of the support column 5.

[0034] Specifically, the base 1 is rectangular in shape and serves as the basic load-bearing component of the equipment. Two lifting lugs 2 are symmetrically distributed on both sides of its top surface and welded perpendicularly to the top surface of the base 1 at a 90° angle. The welding is done using a continuous full-welding process. The two lifting lugs 2 are located near the edges on both sides of the top surface of the base 1, with a spacing adapted to the hand chain hoist 4. A circular lifting hole 3 is formed in the center of the surface of each lifting lug 2. The diameter of the lifting hole 3 is larger than the diameter of the hook of the hand chain hoist 4, ensuring that the hook of the hand chain hoist 4 can be smoothly hooked into the lifting hole 3. A support column 5 is vertically welded to the center of the top surface of the base 1, along its length axis. The top of the support column 5 is rotatably connected to a rotating seat 6, allowing the rotating seat 6 to rotate flexibly around the central axis of the support column 5. The rotating seat 6 has a groove structure adapted to accommodate a hydraulic cylinder, stably housing the hydraulic cylinder and ensuring that the hydraulic cylinder rotates synchronously with the rotating seat 6.

[0035] The lifting lugs 2 and lifting holes 3 on both sides of the base 1 cooperate with the hand-operated hoist 4 to realize the up and down movement of the device and hydraulic cylinder, meeting the height requirements during maintenance. The rotating connection between the support column 5 in the middle of the base 1 and the rotating seat 6 can drive the hydraulic cylinder to rotate along the central axis of the support column 5, making it easy to screw the threads of the hydraulic cylinder main shaft into the grate hydraulic cylinder fixing head. The combination of these two features allows for flexible adjustment of the height and rotation state of the hydraulic cylinder during maintenance, effectively assisting on-site maintenance, reducing maintenance time, and improving efficiency.

[0036] Example 2

[0037] Based on Embodiment 1, as a connection method between the support column 5 and the rotating seat 6, the top of the support column 5 is provided with a connecting column 501, and the bottom of the rotating seat 6 is provided with a cylinder 601. The cylinder 601 is sleeved on the outside of the connecting column 501, so that the support column 5 and the rotating seat 6 are rotatably connected.

[0038] Specifically, the bottom center of the rotating seat 6 extends downward to form a cylinder 601. The inner diameter of the cylinder 601 is adapted to the outer diameter of the connecting column 501. The cylinder 601 is fitted onto the outside of the connecting column 501 in a clearance fit manner. The two can rotate relative to each other, thereby realizing the rotational connection between the support column 5 and the rotating seat 6.

[0039] Example 3

[0040] Based on Embodiment 1, another connection method between the support column 5 and the rotating seat 6 is as follows: Figure 3 , Figure 4 As shown, a first connecting hole 502 is provided at the center of each support column 5, and a second connecting hole 602 is provided at the center of the rotating seat 6, which is concentric with the first connecting hole 502. A positioning pin 7 is inserted into the first connecting hole 502 and the second connecting hole 602.

[0041] Specifically, a first connection 502 is provided at the center of the support column 5 along its central axis, penetrating the upper surface of the support column 5; a rotating seat 6 is located at the top of the support column 5, and a second connection hole 602 is provided at the center of its bottom corresponding to the position of the first connection hole 502, and the second connection hole 602 is concentric with the first connection hole 502 (i.e., the central axes of the two holes are completely coincident). A positioning pin 7 is inserted into both the first connection hole 502 and the second connection hole 602, allowing the rotating seat 6 to rotate flexibly relative to the support column 5 about the positioning pin 7 as an axis.

[0042] Example 4

[0043] In an embodiment of this utility model, a rubber anti-slip layer is provided on the inner surface of the rotating seat 6.

[0044] The rotating base 6 is square in shape, and the length of any side of the rotating base 6 is 20cm to 30cm.

[0045] The diameter of the lifting hole 3 is 3cm to 5cm.

[0046] The base 1 is also provided with fixing holes 8. Several fixing holes 8 are distributed at intervals along the length of the base 1, which are used to detachably fix the auxiliary device to the external support by bolts.

[0047] Specifically, the rotating base 6 is square in shape, with the length of any side ranging from 20cm to 30cm, suitable for the placement requirements of most grate hydraulic cylinders, preferably 25cm. The inner surface of the rotating base 6 (i.e., the inner wall surface in contact with the hydraulic cylinder) is completely fitted with a rubber anti-slip layer. This anti-slip layer is fixed to the rotating base by adhesive or embedded installation to enhance friction when the hydraulic cylinder is placed. The lifting hole 3 on the surface of the lifting lug 2 has a diameter of 3cm to 5cm, which matches the diameter of the hand-operated hoist hook, ensuring that the hook can be stably hooked into the lifting hole 3 and is not easily dislodged.

[0048] The surface of the base 1 has several fixing holes 8 spaced along its length. The fixing holes 8 penetrate the upper and lower surfaces of the base 1. The auxiliary device can be detachably fixed to an external support (maintenance platform or ground bracket) by bolts passing through the fixing holes 8, so as to achieve stable installation.

[0049] Based on the above embodiments, the working process of the auxiliary device for overhauling the grate hydraulic cylinder disclosed in this utility model is as follows:

[0050] During maintenance, the hydraulic cylinder to be inspected is first placed inside the rotating base 6. The hook of the hand-operated hoist 4 is then hooked into the lifting hole 3 of the lifting lug 2. The hand-operated hoist 4 is then raised or lowered, causing the base 1, support column 5, rotating base 6, and hydraulic cylinder to move up and down synchronously. The rotating base 6 is then rotated along the central axis of the support column 5, which in turn causes the internal hydraulic cylinder to rotate synchronously. This achieves precise alignment and screwing of the hydraulic cylinder main shaft threads with the grate hydraulic cylinder fixing head, completing the operation.

[0051] 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 the 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
