[0003] Maintenance platforms are an important component of light steel structure workshops, required for high-altitude construction work or the maintenance of large equipment. Traditional fixed maintenance platforms cannot be moved, failing to meet the safety requirements for high-altitude maintenance operations in different locations. Existing technologies, such as the mobile construction platform disclosed in patent CN203701556U, enable the platform to move by installing brake pulleys at the bottom of the platform columns.
[0004] While the above-mentioned solution enables the movement of the maintenance platform, the following problems still exist: the bottom of the construction platform is not fixed, and the platform will move when the braking function of the brake pulley fails; furthermore, the existing maintenance platform is a standard frame structure, which allows for maintenance by bringing the platform close to the equipment or facility to be maintained; however, there may be other equipment or facilities shorter than the equipment or facility to be maintained outside some of these facilities, making it impossible for the existing maintenance platform to get close to them. Utility Model Content
[0005] To address the aforementioned issues, this utility model provides a non-fixed steel structure maintenance platform. A fixing device is installed on the bottom crossbeam. When the maintenance platform reaches the maintenance position, the claw-shaped support of the fixing device contacts the ground, preventing the maintenance platform from moving even if the self-locking function of the self-locking casters fails. An extension platform is fixedly connected to one side of the frame platform. When there are other equipment or facilities shorter than the equipment or facility to be maintained outside the equipment or facility to be maintained, the bottom of the extension platform does not have a continuous column, allowing it to approach the equipment to be maintained.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A non-fixed steel structure maintenance platform includes a top platform, which is divided into several fixedly connected frame platforms. Each frame platform is fixedly connected to an extension platform, and the extension platforms are fixedly connected to each other.
[0008] Each frame platform is fixedly connected to four columns at the bottom corners, and each extended platform is fixedly connected to two diagonal columns at the bottom corners away from the frame platform; each column is equipped with a self-locking caster wheel at the bottom, and the bottom of the column is connected by a bottom crossbeam, with a fixing device in the middle of each bottom crossbeam.
[0009] On the side of the frame platform away from the extension platform, the columns on both sides face away from the extension platform and are hinged with telescopic diagonal braces.
[0010] Preferably, both the frame platform and the extension platform are composed of four top crossbeams fixedly connected end to end, and the frame platforms, the extension platforms, and the extension platforms share a single top crossbeam.
[0011] Preferably, a support plate is fixedly installed at the top of the column and the inclined column, and the support plate is located at the bottom of the connection of multiple top beams, with the top beams fixedly connected to the support plate.
[0012] Preferably, the bottom end of the inclined column is fixedly connected to the column on the same side, and an inclined reinforcing bar is provided between adjacent columns.
[0013] Preferably, the fixing device includes a threaded tube fixedly disposed in the middle of the bottom crossbeam, the threaded tube being threadedly connected to a threaded rod, and a claw-shaped support being fixedly connected to the bottom of the threaded rod.
[0014] Preferably, the fixing device further includes a rotating handle fixedly connected to the top of the threaded rod, and two nuts are threadedly connected to the body of the threaded rod, one nut being located below the threaded tube and the other nut being located above the threaded tube.
[0015] Preferably, a guardrail is provided at the top of the top platform, and a grid plate is fixed to the top of the top platform inside the guardrail.

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0030] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a non-fixed steel structure maintenance platform, such as... Figure 1 As shown, the system includes a top platform 1, which is divided into several frame platforms 11. Each frame platform 11 is fixedly connected to an extension platform 12. The frame platforms 11 are fixedly connected to each other, and the extension platforms 12 are fixedly connected to each other. The top platform 1 consists of several welded and fixed top beams 4. Specifically, both the frame platforms 11 and the extension platforms 12 consist of four fixedly connected top beams 4. Every two frame platforms 11 share one top beam, every two extension platforms 12 share one top beam, and the frame platforms and extension platforms share one top beam.
[0031] In this embodiment, the top platform 1 includes two frame platforms 11 and two extension platforms 12.
[0032] like Figure 1 As shown, several columns 2 are fixedly installed at the bottom of the top platform 1. Specifically, the columns 2 are only installed at the four bottom corners of the frame platform 11. It can be understood that since every two frame platforms 11 share a top beam 4, two frame platforms 11 will share two corners. Therefore, in this embodiment, six columns are installed.
[0033] Specifically, a support plate 21 is fixedly installed on the top of the column 2. The support plate 21 is actually located at the connection point of multiple top crossbeams 4, so that all the interconnected top crossbeams 4 are fixedly connected to the support plate 21. In this embodiment, since every two frame platforms 11 share a top crossbeam 4, and the frame platform and the extension platform also share a top crossbeam, some support plates 21 will have two top crossbeams 4 connected and fixed on their tops, some support plates 21 will have three top crossbeams connected and fixed on their tops, and some support plates 21 will have four top crossbeams connected and fixed on their tops.
[0034] like Figure 1 As shown, several inclined columns 3 are fixedly installed at the bottom of the top platform 1, and support plates 21 are also installed at the top of the inclined columns 3. The tops of the inclined columns 3 are fixedly connected to the bottom of the two corners of the extension platform 12 away from the frame platform 11. It can be understood that since every two extension platforms 12 share a top crossbeam 4, two extension platforms 12 will share two corners. Therefore, in this embodiment, three inclined columns 3 are provided.
[0035] Understandably, the support plate 21 at the top of the inclined column 3 is also located at the connection point of the multiple top beams 4, so that the multiple interconnected top beams 4 are all fixedly connected to the support plate 21 at the top of the inclined column 3. The bottom end of the inclined column 3 is fixed to the column 2. Specifically, the bottom end of the inclined column 3 is fixedly connected to the column 2 on the same side.
[0036] The top beam is effectively supported by the support plate 21, the frame platform 11 is supported by the columns 2, and the extension platform is supported by the diagonal columns 3 and 2. To ensure stability, diagonal reinforcing bars 22 are also installed between adjacent columns 2.
[0037] Understandably, the height of column 2 is set according to the actual factory environment, and the space dimensions at the bottom of extension platform 12 also need to be set according to the actual situation.
[0038] The purpose of setting up the extension platform 12 is to overcome the situation where there are other devices or facilities shorter than the equipment or facility to be repaired outside the equipment or facility to be repaired, as the space at the bottom of the extension platform 12 can overcome this situation. Because the bottom of the extension platform does not have a continuous column or diagonal reinforcing bar, there is enough space to get close to the equipment to be repaired.
[0039] Each column 2 is equipped with a caster wheel at its bottom, enabling the maintenance platform to move. In this embodiment, the caster wheel is a self-locking caster wheel 10. The bottom of the column 2 is connected by a bottom crossbeam 5, and a fixing device 6 is set in the middle of each bottom crossbeam 5. The function of the fixing device 6 is to provide an additional protection measure when the top platform 1 moves to the corresponding position under the action of the self-locking caster wheel 10, even if the self-locking function of the self-locking caster wheel 10 fails, so as to prevent the maintenance platform from moving.
[0040] Specifically, the fixing device 6 includes a threaded tube 61 fixedly installed in the middle of the bottom crossbeam 5, the threaded tube 61 passing through the upper and lower surfaces of the bottom crossbeam 5, and a threaded rod 62 threadedly connected to the threaded tube 61, with a claw-shaped support 63 fixedly connected to the bottom of the threaded rod 62. The threaded rod 62 drives the claw-shaped support 63 to move downwards until it contacts the ground, preventing the top platform 1 from moving when the self-locking caster wheel 10 fails.
[0041] The fixing device 6 also includes a rotating handle 64 fixedly connected to the top of the threaded rod 62. By rotating the rotating handle 64, the threaded rod 62 causes the claw-shaped support 63 to move up and down relative to the threaded tube 61. Two nuts 65 are threadedly connected to the body of the threaded rod 62, one nut 65 is located below the threaded tube 61, and the other nut 65 is located above the threaded tube 61. When the rotating handle 64 is rotated, the claw-shaped support 63 moves downward and contacts the ground. Then, the two nuts 65 are tightened so that the two nuts 65 contact the threaded tube 61 from top to bottom and from bottom to top, respectively, preventing the threaded rod 62 from rotating relative to the threaded tube 61.
[0042] When the maintenance platform needs to be moved, first tighten the upper and lower nuts 65 to the top and bottom of the threaded rod 62 respectively, and then turn the rotating handle 64 to lift the claw support 63.
[0043] In this embodiment, a guardrail 9 is provided on the top of the top platform 1. Inside the guardrail 9, a grating plate is fixed to the top of the top platform 1. The maintenance workers stand on the grating plate and carry out maintenance work under the protection of the guardrail.
[0044] In this embodiment, a ladder 8 is fixedly installed at the middle position on the side of the frame platform 11 away from the extension platform 12. Correspondingly, the guardrail 9 has an opening at the ladder position to facilitate maintenance workers to reach or exit the top platform 1. Maintenance workers need to climb up and down the ladder to the top platform 1. To ensure safety and prevent the maintenance platform from overturning, telescopic diagonal braces 7 are installed on the two uprights 2 on the side of the ladder facing away from the extension platform.
[0045] Specifically, a telescopic brace 7 is hinged to the side of the column 2 away from the extension platform 12. The telescopic brace 7 includes a telescopic rod 71, which is slidably sleeved inside a telescopic sleeve rod 72. Both the telescopic rod 71 and the telescopic sleeve rod 72 have several pairs of locking holes 73, and locking rods 74 are installed in the locking holes 73. The relative position of the telescopic rod 71 and the telescopic sleeve rod 72 is adjusted to adjust the length of the telescopic brace 7. Then, the locking holes 73 of the telescopic rod 71 and the telescopic sleeve rod 72 are aligned, and the locking rods 74 are inserted into them.
[0046] A connecting ear plate can be fixedly installed at the end of the telescopic sleeve rod 72 away from the telescopic rod 71, and a connecting ear plate can be fixedly installed on the side of the column 2 away from the extension platform 12. After the two connecting ear plates are aligned, a pin is inserted to make the column 2 hinged to the telescopic diagonal brace 7.
[0047] Based on the actual space available on site, adjust the length of the telescopic brace 7 and its angle relative to the column 2 so that one end of the telescopic brace 7 rests on the ground. When moving the maintenance platform, first adjust the length of the telescopic brace 7 to its shortest length, and then attach it to the column 2.
[0048] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
