Description

Technical Field

[0001] The present application relates to the field of mechanical engineering technology, and in particular to a boiler maintenance auxiliary device. Background Art

[0002] A boiler is an energy conversion device. Under long-term high-temperature operation, some parts are prone to failure and often require maintenance by staff. Currently, most detection platforms are used to carry out auxiliary maintenance activities of boilers.

[0003] Most of the existing maintenance auxiliary devices can adjust the height and position of the detection platform. After searching, for example, the Chinese utility model patent with publication number CN214087591U provides an overload protection device for a boiler maintenance platform. A scissor-type lifting frame is arranged under the maintenance platform of the device. The height of the load-bearing plate is adjusted by the scissor-type lifting frame, and the position of the load-bearing plate can be adjusted by the universal wheel.

[0004] However, when using the maintenance auxiliary device, the operator is usually required to carry a tool box to the inspection platform. When the operator needs to use the tool, since the tool box is placed directly on the inspection platform, the operator needs to bend down repeatedly to take the tool, which makes it inconvenient to take the tool. Therefore, it is necessary to provide a boiler maintenance auxiliary device to solve the above problem.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a boiler maintenance auxiliary device, which achieves the effect of facilitating the operator to take and replace tools by providing a box placement table.

[0007] The technical solution adopted by the present application to solve the technical problem is: a boiler maintenance auxiliary device having a maintenance platform, the maintenance platform comprising:

[0008] A protection part, which is used to protect the workers on the maintenance platform;

[0009] A lifting mechanism, which is used to adjust the height of the maintenance platform;

[0010] A box placing table, which is used to place the operator's tool box;

[0011] An adjustment mechanism is provided at one end of the box placing platform, and is used to adjust the position of the box placing platform. The adjustment mechanism has:

[0012] A support plate, the support plate is fixed on the protection part;

[0013] A lead screw, the lead screw being rotatably connected to the support plate;

[0014] A nut, the nut being connected to an end surface of the box placing platform close to the lead screw, the nut and the lead screw being threadedly connected;

[0015] A fixing mechanism is used to fix the position of the box placing platform.

[0016] Furthermore, the lower end of the lead screw is rotatably connected to a mounting seat, one end of the mounting seat is fixedly mounted with a fixing block, and the fixing block is fixed to the inner wall of the support plate.

[0017] Furthermore, the fixing mechanism has a ratchet fixed on the lead screw, a fixing frame is provided on one side of the ratchet, the fixing frame is fixed on the fixing block, a latch tooth is hinged on the fixing frame, and the latch tooth is engaged with the ratchet tooth of the ratchet.

[0018] Furthermore, a mounting plate is fixedly mounted on the fixing frame, an adjusting block is slidably connected to the mounting plate, an adjusting rod is hinged at one end of the adjusting block close to the latch tooth, the other end of the adjusting rod is connected to the latch tooth, a supporting shaft is rotatably connected to the adjusting rod, the lower end of the supporting shaft is fixedly connected to the fixing frame, and a torsion spring is sleeved on the supporting shaft.

[0019] Furthermore, a moving trolley is fixedly mounted on the lower end of the lifting mechanism.

[0020] Furthermore, bearing seats are provided at both ends of the lead screw.

[0021] The beneficial effect of the present application is that the boiler maintenance auxiliary device provided by the present application is provided with a storage box and a ratchet. If the position of the box platform needs to be adjusted, the box platform is manually pulled upward. During the adjustment process, the lead screw rotates clockwise while driving the ratchet to rotate clockwise. At this time, the ratchet teeth of the ratchet push the latch teeth outward so that the ratchet will not be affected by the latch teeth. After adjusting to its appropriate position, the box platform is released. At this time, the box platform will give the nut a downward gravity, but because the nut is downward, the lead screw will drive the ratchet to rotate counterclockwise, thereby engaging the ratchet through the latch teeth to prevent the ratchet from rotating counterclockwise, thereby fixing the box platform, making it convenient for the operator to take and replace tools.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0037] like Figure 1 As shown, the present application provides a boiler maintenance auxiliary device, including an maintenance platform 1, on the upper end of which are fixedly mounted a plurality of guardrails 11, and the plurality of guardrails 11 form a surrounding structure, constituting a protective portion of the maintenance platform 1, for protecting the workers on the maintenance platform 1.

[0038] A lifting mechanism 2 is fixedly installed at the lower end of the maintenance platform 1, and the lifting mechanism 2 is used to adjust the height of the maintenance platform 1. The lifting mechanism 2 is a prior art and can be referred to in the Chinese invention patent with publication number CN109678077B, which will not be described in detail here.

[0039] A moving trolley 6 is fixedly mounted at the lower end of the lifting mechanism 2 , and the position of the maintenance platform 1 is adjusted by the moving trolley 6 .

[0040] like Figure 1-Figure 3 As shown, a box placing platform 5 is provided on the inner side of the guardrail 11, and the box placing platform 5 is used to place the operator's tool box. The size of the box placing platform 5 can be set according to the size of the tool box.

[0041] In order to adjust the position of the box placing platform 5, an adjusting mechanism 3 is provided at the rear end of the box placing platform 5. The adjusting mechanism 3 has a support plate 31 fixed on the guardrail 11. An empty groove (not marked in the figure) is opened on the end surface of the support plate 31 away from the guardrail 11. A lead screw 32 is rotatably connected in the empty groove. It can be understood that bearing seats (not marked in the figure) are provided at both ends of the lead screw 32, and the lead screw 32 is connected to the inside of the support plate 31 through the bearing seats to ensure the stability of the rotation of the lead screw 32.

[0042] At the same time, if Figure 5 As shown, a nut 33 is fixedly installed on one end face of the box placing platform 5 close to the lead screw 32, and the nut 33 is threadedly connected to the lead screw 32, and a mounting seat 35 is rotatably connected to the lower end of the lead screw 32, and a fixing block 34 is fixedly installed on one end of the mounting seat 35, and the fixing block 34 is fixed to the inner wall of the support plate 31, thereby guiding and supporting the lead screw 32.

[0043] If the position of the box placing platform 5 needs to be adjusted upward, the box placing platform 5 is manually held, and the position of the nut 33 is moved, so that the lead screw 32 rotates clockwise, thereby realizing the up and down movement of the box placing platform 5.

[0044] In order to fix the position of the box platform 5, a fixing mechanism 4 is provided at the bottom of the screw 32, and the fixing mechanism 4 has a ratchet 41 fixed on the screw 32, and the ratchet 41 is located below the mounting seat 35, and a fixing frame 42 is provided on one side of the ratchet 41, and the fixing frame 42 is fixed on the fixing block 34, and a latch tooth 43 is hinged on the fixing frame 42, and under normal conditions, the latch tooth 43 is engaged with the ratchet tooth of the ratchet 41.

[0045] In order to adjust the position of the latch tooth 43, a mounting plate 44 is fixedly mounted on the fixing frame 42, and an adjusting block 45 is slidably connected to the mounting plate 44. An adjusting rod 46 is hinged at one end of the adjusting block 45 close to the latch tooth 43, and the other end of the adjusting rod 46 is hinged to the latch tooth 43. At the same time, a supporting shaft (not shown in the figure) is rotatably connected to the adjusting rod 46, and the lower end of the supporting shaft is fixedly connected to the fixing frame 42, and a torsion spring 48 is sleeved on the supporting shaft, and the torsion spring 48 is fixedly mounted to the adjusting rod 46.

[0046] To sum up, under normal conditions, the box placing platform 5 is located at a lower position of the screw 32. At this time, after the worker climbs onto the maintenance platform 1, he manually pulls the box placing platform 5 upwards. During the adjustment process, the screw 32 rotates clockwise while driving the ratchet 41 to rotate clockwise. At this time, the ratchet teeth of the ratchet 41 push the latch teeth 43 outward, so that the ratchet 41 will not be affected by the latch teeth 43. After adjusting to its appropriate position, the box placing platform 5 is released. At this time, the box placing platform 5 will give the nut 33 a downward gravity, but because the nut 33 is downward, the screw 32 will drive the ratchet 41 to rotate counterclockwise, thereby engaging the ratchet 41 through the latch teeth 43 to prevent the ratchet 41 from rotating counterclockwise, thereby fixing the box placing platform 5, making it convenient for the operator to take and replace tools.

[0047] If the worker needs to adjust the position of the box platform 5 downward or reset the box platform 5, the worker presses the adjusting block 45 inward with his foot, and the adjusting block 45 drives the adjusting rod 46 inward. At this time, the adjusting rod 46 rotates through the torsion spring 48 to drive the locking tooth 43 outward, thereby canceling the engagement of the ratchet 41, allowing the ratchet 41 to rotate normally, so that the worker can pull the box platform 5 downward. When the adjustment is completed, the worker releases the adjusting block 45 with his foot, and the locking tooth 43 is reset through the torsion spring 48, and the ratchet 41 is engaged and fixed again.

[0048] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
