It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0025] like Figure 1 , 2As shown in Figure 3, an embodiment of the present invention discloses a mobile maintenance equipment for a metallurgical crane, including a traveling mechanism 1, wherein the traveling mechanism 1 includes two symmetrically arranged tracks 11, each of the tracks 11 is slidably provided with a support frame 12, a support mechanism 2 is provided between the two support frames 12, the support mechanism 2 includes a support platform 21, two climbing ladders 22 are symmetrically provided on the lower side of the support platform 21, the climbing ladders 22 extend downward to the lower side of the tracks 11, two manholes 23 are symmetrically provided on the support platform 21, the two manholes 23 are respectively located on one side of the two climbing ladders 22, a maintenance mechanism 3 is fixedly provided at the lower ends of the two climbing ladders 22, the maintenance mechanism 3 includes a maintenance platform 31, a protective frame 32 is fixedly provided on the maintenance platform 31, the maintenance platform 31, the climbing ladders 22 and the support platform 21 together form a maintenance space, and the crane 4 is located in the maintenance space.

[0026] Specifically, during use, when the crane needs to be inspected, the maintenance personnel enter the support platform 21, and then enter the climbing ladder 22 through the manhole 23, and then move downward along the climbing ladder 22, and move to the maintenance platform 31 to inspect the crane in the maintenance space, and the maintenance personnel can move on the maintenance platform 31 to inspect various horizontal parts of the crane; during the maintenance process, the moving travel mechanism 1, the support frame 12 moves on the track 11, and the support frame 12 drives the maintenance platform 31 to move through the support mechanism 2, so that the maintenance personnel can inspect various longitudinal parts of the crane. During the maintenance process, the protection frame 32 protects the maintenance personnel to prevent the maintenance personnel from falling from the maintenance platform 31. After the maintenance is completed, the maintenance personnel moves upward through the climbing ladder 22 and enters the support platform 21 from the manhole.

[0027] By setting the traveling mechanism 1, the maintenance mechanism 3 can be driven to move, thereby increasing the effective area that the maintenance mechanism 3 can inspect. By setting the maintenance platform 31, maintenance personnel can move on the maintenance platform 31, thereby further increasing the effective area that the maintenance mechanism 3 can inspect. By setting the climbing ladder 22 and the manhole 23, the movement of maintenance personnel is facilitated. By setting the protective frame 32, maintenance personnel can be protected while working on the maintenance platform 31 to prevent them from falling.

[0028] like Figure 2 , 3As shown in Figure 5, the bottom end of the climbing ladder 22 is fixedly connected to a support rod 24, the inspection platform 31 is fixedly connected to the two support rods 24, and the two sides of the climbing ladder 22 are respectively fixedly connected to the protective frame 32 with a diagonal rod 33, the diagonal rod 33 and the protective frame 32 and the climbing ladder 22 form a right triangle, and the diagonal rod 33 is located on the side of the climbing ladder 22 close to the other climbing ladder 22.

[0029] Specifically, during installation, the inspection platform 31 is first fixedly connected to the two support rods 24 , and then the protection frame 32 is fixedly connected to the inspection platform 31 , and then the inclined rod 33 is fixedly connected to the climbing ladder 22 and the protection frame 32 .

[0030] By setting the support rod 24, the maintenance platform 31 can be installed on the climbing ladder 22, and then by setting the inclined rod 33, the middle section of the protection frame 32 can be fixed to the climbing ladder 22, so that the middle section of the maintenance platform 31 is more stable, improving the stability of the maintenance mechanism 3 and the connection safety.

[0031] like Figure 3 , 5 As shown in Figures 7 and 11, the maintenance mechanism 3 also includes a lifting member 34 arranged on the maintenance platform 31, and the lifting member 34 includes a lifting platform 341 that moves up and down, and the lifting platform 341 is symmetrically fixedly connected with guardrails 342 on both sides close to the protective frame 32, and the lifting platform 341 is hinged with opening and closing fences 343 at both ends close to the climbing ladder 22, and a connecting member 35 is arranged between the opening and closing fence 343 and the guardrail 342.

[0032] Specifically, in the initial state, the lower side of the lifting platform 341 contacts the upper side of the maintenance platform 31, and the two opening and closing bars 343 are in a horizontal state. When in use, when the maintenance personnel need to perform maintenance on a crane at a higher position, the maintenance personnel walk from the maintenance platform 31 to the lifting platform 341, and then rotate the two opening and closing bars 343 so that the opening and closing bars 343 are flipped 90° in the direction close to the guardrail 342, and then the opening and closing bars 343 are connected to the guardrail 342 through the connecting piece 35, and then the lifting platform 341 is moved upward, and the lifting platform 341 drives the maintenance personnel to move upward, and at the same time, the lifting platform 341 drives the guardrail 342 and the opening and closing bars 343 to move upward.

[0033] By setting the lifting member 34, the maintenance personnel can be moved to a higher position on the maintenance platform 31, so that the maintenance personnel can perform maintenance on the higher position of the crane. At the same time, by setting the guardrail 342 and the opening and closing fence 343, the maintenance personnel can be protected when the lifting platform 341 is raised, and by setting the opening and closing fence 343 and the lifting platform 341, the maintenance personnel can enter the lifting platform 341 conveniently, and when the lifting platform 341 does not need to be moved, it is convenient for the maintenance personnel to move on the maintenance platform 31.

[0034] like Fig.11 As shown, the opening and closing fence 343 includes a mounting frame 344, an end of the mounting frame 344 is hinged to the end of the lifting platform 341, the end of the lifting platform 341 is fixedly connected with a connecting shaft, a through hole is opened on the mounting frame 344, the connecting shaft passes through the through hole, and the connecting shaft is rotatably connected to the through hole, six protective rods 345 are fixedly connected at equal intervals in the mounting frame 344, and the axis of the protective rod 345 is perpendicular to the axis direction of the lifting platform 341.

[0035] Specifically, when in use, when the opening and closing bar 343 needs to be turned over, the installation frame 344 is rotated, and the installation frame 344 rotates, and the installation frame 344 drives the protection rod 345 to rotate.

[0036] The hinged connection between the opening and closing fence 343 and the lifting platform 341 facilitates the rotation of the opening and closing fence 343 , thereby facilitating maintenance personnel to enter and exit the lifting platform 341 without affecting the maintenance personnel's normal movement on the maintenance platform 31 .

[0037] like Fig. 9 , 11 As shown, connecting members 35 are respectively provided at both ends of the guardrail 342, and the connecting member 35 includes a limit plate 351 fixedly connected to the guardrail 342, and the opening and closing fence 343 can abut against the limit plate 351. The connecting member 35 also includes a connecting rod 352 rotatably connected to the guardrail 342, and a magnetic block 353 is fixedly connected to the guardrail 342, and the magnetic block 353 can be magnetically attracted to the guardrail 342. The magnetic block 353 is located on the side of the connecting rod 352 away from the opening and closing fence 343, and the top of the connecting rod 352 is fixedly connected to an arc hook 354.

[0038] Specifically, in the initial state, the connecting rod 352 and the magnet block 353 are magnetically attracted to each other, and the connecting rod 352 remains in a vertical state; when in use, when the opening and closing bar 343 flips upward and the opening and closing bar 343 abuts against the limit plate 351, the connecting rod 352 is rotated so that the arc hook 354 is buckled on the protective rod 345, thereby connecting the opening and closing bar 343 to the protective rod 342; when the maintenance personnel need to inspect the higher positions on both sides of the lifting platform 341, the connecting rod 352 is moved so that the arc hook 354 is removed from the protective rod 345, and then the opening and closing bar 343 is rotated so that the opening and closing bar 343 flips to a certain angle to the side away from the protective rod 342, and then the connecting rod 352 is rotated so that the arc hook 354 is buckled on the corresponding protective rod 345.

[0039] By setting the connecting piece 35, the opening and closing fence 343 can be connected to the guardrail 342 to ensure the protection of personnel after the lifting platform 341 is raised, and by setting the guardrail 345 and the arc hook 354, the inclination angle of the opening and closing fence 343 can be appropriately adjusted to further expand the safe maintenance area for maintenance personnel.

[0040] like Figure 7 , 8 As shown in Figure 10, a fastening member 36 is provided between the opening and closing fence 343 and the inspection platform 31, and the fastening member 36 includes a torsion spring 361 provided between the opening and closing fence 343 and the lifting platform 341. A fixing block 362 is fixedly connected to the inspection platform 31. An opening 363 opening downward is provided on the opening and closing fence 343, and the fixing block 362 can be inserted into the opening 363. A sliding groove 364 opening upward is provided in the opening and closing fence 343, and the side of the sliding groove 364 The wall is connected to the opening 363, and the fixed block 362 is provided with a mounting groove 365 opening toward the sliding groove 364. The mounting groove 365 is slidably connected with an insertion block 366, and a first spring is connected between the insertion block 366 and the mounting groove 365. The top surface of one end of the insertion block 366 inserted into the sliding groove 364 is an inclined surface, and the sliding groove 364 is slidably connected with a sliding rod 367, and a second spring 368 is connected between the sliding rod 367 and the opening and closing bar 343.

[0041] Specifically, during use, when the opening and closing bar 343 is in a horizontal state, the torsion spring 361 is in a force storage state, and at the same time the fixed block 362 is inserted into the opening 363, and at the same time the insertion block 366 is inserted into the sliding groove 364; when the opening and closing bar 343 needs to be flipped upward, the maintenance personnel presses the sliding rod 367 downward, and the sliding rod 367 compresses the second spring 368. At the same time, the bottom end of the sliding rod 367 abuts against the inclined surface of the insertion block 366, so that the insertion block 366 compresses the first spring and enters the installation groove 365. When the insertion block 366 completely enters the installation groove 365, the opening and closing bar 343 flips upward under the action of the torsion spring 361.

[0042] By setting the fastening piece 36, the opening and closing bar 343 can be fastened to the maintenance platform 31 to prevent the opening and closing bar 343 from moving when not in use and affecting the maintenance work of the maintenance personnel. By setting the torsion spring 361, when the opening and closing bar 343 needs to be used, the fixing block 362 is unlocked, and the opening and closing bar 343 automatically flips upward under the action of the torsion spring 361, which is convenient for use.

[0043] like Figure 3 , 7 As shown in Figures 9, 10 and 11, the maintenance mechanism 3 also includes a moving part 37, and the moving part 37 includes two slide grooves opened in the lifting platform 341, and two extension rods 371 are symmetrically slidably connected in each of the slide grooves, and an electromagnetic slide rail 372 is fixedly connected to each of the inclined rods 33, and an electromagnetic slider 373 is slidably connected in the electromagnetic slide rail 372, and a first motor 374 is fixedly connected to the electromagnetic slider 373, and a winding wheel 375 is fixedly provided on the output end of the first motor 374, and a pull rope 376 is wound around the winding wheel 375, and the pull rope 376 is fixedly connected to the adjacent extension rod 371.

[0044] Specifically, during use, when the lifting platform 341 needs to move upward, the first motor 374 is started, and the output end of the first motor 374 drives the winding wheel 375 to rotate, and the winding wheel 375 contracts the pull rope 376, so that the extension rod 371 moves upward, and at the same time, the extension rod 371 drives the lifting platform 341 to move upward. When the pull rope 376 is completely contracted, the electromagnetic slider 373 is started, and the electromagnetic slider 373 slides upward in the electromagnetic slide rail 372. At the same time, the electromagnetic slider 373 drives the extension rod 371 to slide upward, and at the same time, the extension rod 371 slides out of the slide groove, and the extension rod 371 drives the lifting platform 341 to continue to move upward.

[0045] By setting the moving part 37, the lifting platform 341 can be driven to move up and down, and the moving part 37 has a simple structure and occupies a small space, which saves the area occupied by the maintenance platform 31, making the effective use area of ​​the maintenance platform 31 larger and improving the maintenance efficiency.

[0046] It should be noted that the electromagnetic slide rail 372 and the electromagnetic slider 373 are prior art and will not be described in detail.

A second motor 132 is fixedly connected to the support frame 12, and the output end of the second motor 132 is fixedly connected to one of the moving wheels 131.

[0048] Specifically, when in use, when the support frame 12 needs to move, the second motor 132 is started, and the output end of the second motor 132 drives the moving wheel 131 to rotate, and the moving wheel 131 moves on the track 11, thereby driving the support frame 12 to move.

[0049] By providing the moving part 13, the support frame 12 can be driven to move, so that the maintenance mechanism 3 can be moved, thereby increasing the maintenance area.

[0050] like Figure 4 As shown, safety guardrails 25 are respectively provided on both sides of the support platform 21 , and the safety guardrails 25 are fixedly connected to the support platform 21 .
