Description

Technical Field

[0001] The present application relates to the field of boiler maintenance equipment, and in particular to a sootblower maintenance platform. Background Art

[0002] In the concrete production process, boilers, mixing tanks and other tanks are needed. After a period of use, a lot of dust will accumulate on the top of these tanks, affecting the operation of the tanks. Therefore, it is convenient to blow high-pressure gas to the top of the tank through a sootblowing pipe to blow away the dust on the top of the tank. However, during the use of the sootblowing pipe, the elbow position near the top of the tank is easily damaged due to pressure and friction with the boiler, resulting in sand holes or holes that leak ash, so the elbow position of the sootblowing pipe at the top of the tank needs to be repaired.

[0003] At present, maintenance personnel usually climb to the top of the tank body with a ladder, fasten their safety belts, and then inspect the top elbow of the sootblower. However, due to the narrow working space and lack of protection after the tank body is sealed, there are great safety risks in the process maintenance. Utility Model Content

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiment of the present application discloses a sootblower maintenance platform.

[0031] Reference Figure 1The sootblower maintenance platform includes a protective frame 1, a cantilever frame 2, a guardrail 3, a crossbar 4, a supporting assembly 5, a footboard 6 and a diagonal brace 7.

[0032] Reference Figure 1 The protective frame 1 is circumferentially installed on the top of the tank body. In this embodiment, the protective frame 1 is a railing composed of a plurality of steel bars combined horizontally and vertically, which circumferentially surrounds the top of the tank body and improves the safety of maintenance personnel on the top of the tank body.

[0033] Reference Figure 1 , Figure 2 The cantilever frame 2 is installed on the protective frame 1, and the cantilever frame 2 extends to the outside of the sootblowing pipe on the tank body. The cantilever frame 2 includes a cantilever plate 21 and a connecting assembly 22. The cantilever plate 21 is horizontally abutted against the outer wall of the tank body. A reserved hole is pre-prepared on the cantilever plate 21, and the sootblowing pipe extends to the top of the tank body through the reserved hole. The guardrail 3 is circumferentially installed on the outer periphery of the cantilever plate 21. In this embodiment, the guardrail 3 is also a railing composed of a plurality of steel rods combined horizontally and vertically; the connecting assembly 22 is installed on the cantilever plate 21, and the connecting assembly 22 is used to connect to the protective frame 1. The connecting assembly 22 includes a connecting rod 221 and a hook 222. The connecting rod 221 is hingedly installed on both sides of the cantilever plate 21, and the hook 222 is installed at the end of the connecting rod 221 away from the cantilever plate 21, and the hook 222 is hooked on the protective frame 1.

[0034] When installing the cantilever frame 2, the maintenance personnel move the cantilever plate 21 so that the soot blowing pipe passes through the pre-reserved hole on the cantilever plate 21, and make the cantilever plate 21 abut against the protective frame 1 in a horizontal state, and then rotate the connecting rod 221, and the connecting rod 221 drives the hook 222 to be hooked on the protective frame 1, so that the cantilever plate 21 can be cantilevered and installed to the soot blowing pipe, which effectively improves the convenience of the maintenance personnel to install the cantilever plate 21; the maintenance personnel can move from the tank body to the cantilever plate 21 to inspect the soot blowing pipe, and the cantilever plate 21 can be cantilevered and installed to the soot blowing pipe. The cantilever plate 21 provides an operating space for maintenance personnel, thereby improving the convenience for maintenance personnel to repair the sootblowing pipe; and the space enclosed by the protective frame 1 and the guardrail 3 fully encloses the maintenance personnel, thereby effectively improving the safety of the maintenance personnel when repairing the sootblowing pipe on the top of the tank body, and the maintenance personnel move the cantilever plate 21 toward the tank body so that the hook 222 is loosened on the protective frame 1, and the position of the cantilever plate 21 can be adjusted, thereby effectively improving the convenience for maintenance personnel to adjust the position of the cantilever plate 21.

[0035] Reference Figure 1 , Figure 2 The footboard 6 is circumferentially installed on the cantilever plate 21 , and the footboard 6 extends upward to close the gap between the top of the cantilever plate 21 and the guardrail 3 .

[0036] The gap between the top of the cantilever plate 21 and the guardrail 3 is closed by the foot plate 6, reducing the possibility of tools placed on the cantilever plate 21 by maintenance personnel falling off the cantilever plate 21, thereby enhancing the safety of the area below the tank body during the maintenance of the sootblower.

[0037] Reference Figure 1 , Figure 2 Two diagonal support rods 7 are installed at the bottom of the cantilever plate 21, and the two diagonal support rods 7 are both abutted against the outer wall of the tank body. The diagonal support rod 7 includes a support sleeve 71 and an abutting rod 72. The support sleeve 71 is installed on the bottom wall of the cantilever plate 21. The end of the support sleeve 71 away from the cantilever plate 21 is open and the inner wall is threaded. The abutting rod 72 is threadedly installed on the inner wall of the support sleeve 71. In this embodiment, a rubber pad is installed at the end of the abutting rod 72 away from the support sleeve 71, which reduces the damage to the tank body caused by the abutting rod 72 abutting against the tank body and enhances the stability of the abutting rod 72 abutting against the tank body.

[0038] The maintenance personnel first rotate the abutment rod 72 to move the abutment rod 72 toward or away from the support sleeve 71 to adjust the length of the diagonal support rod 7. When the maintenance personnel install the cantilever plate 21 on the protective frame 1, the diagonal support rod 7 can abut against the outer wall of the tank body to support the bottom of the cantilever plate 21, thereby effectively improving the stability of the cantilever plate 21. The maintenance personnel can also rotate the abutment rod 72 at any time to adjust the length of the diagonal support rod 7, thereby improving the applicability of the diagonal support rod 7 to support the cantilever plate 21 at different positions.

[0039] Reference Figure 1 , Figure 2 The cross bar 4 is circumferentially installed on the guardrail 3 along the outer periphery of the cantilever plate 21, and the support assembly 5 is installed on the guardrail 3. The support assembly 5 is used to support the cross bar 4. The support assembly 5 includes a support rod 51 and a return spring 52. The support rod 51 is hingedly installed on the guardrail 3 along the length direction of the cross bar 4. One end of the return spring 52 is installed on the guardrail 3, and the other end of the return spring 52 is installed on the support rod 51. The return spring 52 always has a tendency to drive the support rod 51 to rotate to abut against the cross bar 4. In this embodiment, two baffles are also installed on the support rod 51 in parallel and at intervals. The parallel direction of the two baffles is consistent with the length direction of the cross bar 4, and the two baffles are respectively abutted on both sides of the cross bar 4, thereby enhancing the supporting effect of the support rod 51 on the cross bar 4.

[0040] When the maintenance personnel moves, the safety belt is driven to move, and the safety belt slides on the cross bar 4. When the safety belt abuts against the support rod 51, as the maintenance personnel continue to move, the safety belt can drive the support rod 51 to rotate and make way, so that the safety belt can pass through the gap between the support rod 51 and the cross bar 4. Then the cross bar 4 is reset under the action of the reset spring 52, and continues to support the cross bar 4, thereby improving the problem that the maintenance personnel need to untie the safety belt when hanging the safety belt on the guardrail 3 and hang the safety belt to other positions of the guardrail 3 again when moving, and effectively improving the convenience of maintenance personnel walking on the cantilever board 21. In addition, the support rod 51 continues to support the cross bar 4, thereby improving the stability of the cross bar 4, thereby improving the safety of the safety belt hung on the cross bar 4.

[0041] The implementation principle of a sootblowing pipe maintenance platform in an embodiment of the present application is as follows: after the maintenance personnel climb onto the tank body, they hang the safety belt on the cross bar 4, and then move to the cantilever plate 21 to inspect the sootblowing pipe. The cantilever plate 21 provides an operating space for the maintenance personnel, which is convenient for the maintenance personnel to inspect the sootblowing pipe. During the maintenance process, the protective frame 1 and the guardrail 3 enclose the maintenance personnel, effectively improving the safety of the sootblowing pipe on the top of the maintenance tank body.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
