Color steel plate Specific implementation mode

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model

[0044] For the convenience of understanding, the traditional operation situation will be described below. Please refer to Figure 1 , the keel 81 is fixedly installed on the top of the building, and the air duct component is located above the keel 81. There are a plurality of mounting holes 82 arranged in a rectangular array on the keel 81, and color steel plates 83 are correspondingly installed at the positions of the mounting holes 82, so as to block the air duct components above. Since the lifting platform of the lift truck 7 has a large size, while the mounting holes 82 have a small size, the lifting platform of the lift truck 7 cannot directly pass through the mounting holes 82. Workers need to remove the color steel plates 83 and build a flat plate on the keel 81, and then the workers stand on the flat plate to operate

[0045] Please refer to Figure 1 , a mounting platform for a lift truck in a restricted space provided by the present utility model will be described below. A mounting platform for a lift truck in a restricted space is used to be arranged on the lift truck 7, and the lift truck 7 is located below the keel 81

[0046] Please refer to Figure 1 and Figure 2, A mounting platform for a lifting vehicle in a confined space, comprising a connecting frame 1, an operating platform 2 and a platform guardrail 3. Among them, the connecting frame 1 is used for fixedly connecting with the guardrail of the lifting vehicle 7 and passing through the mounting hole 82. The lower part size of the connecting frame 1 matches that of the guardrail of the lifting vehicle 7, so that the lower part of the connecting frame 1 fits better with the guardrail of the lifting vehicle 7 and is more stable after connection. And the upper part size of the connecting frame 1 is smaller than the size of the mounting hole 82, so that the upper part of the connecting frame 1 can avoid the keel 81 and pass through the mounting hole 82. The operating platform 2 is fixedly arranged on the connecting frame 1 for the staff to stand on. The platform guardrail 3 is fixedly arranged on the connecting frame 1 and encloses a space for the staff to stand in.

[0047] Specifically, during operation, the staff needs to first remove the color steel plate 83 installed on the keel 81, so as to expose the mounting hole 82 on the keel 81. It should be understood that when removing the color steel plate 83, only the color steel plate 83 located below the air duct component needs to be removed, and it is not necessary to remove all the color steel plates 83. After removing the color steel plate 83, the lifting platform of the lifting vehicle 7 drives the connecting frame 1 to rise, so that the connecting frame 1 can avoid the position of the keel 81 and pass through from the mounting hole 82.

[0048] The operating platform 2 is lifted above the keel 81, so that the staff standing on the operating platform 2 is closer to the air duct component, which facilitates the staff to perform operation and maintenance. There is no need for the staff to build a flat plate on the keel 81, reducing the operation risk and the complexity of the operation. At the same time, the platform guardrail 3 surrounding the staff plays a protective role for the staff, making it difficult for the staff to fall from a height during operation and reducing the operation risk.

[0049] In some embodiments, please refer to Figure 2 and Figure 3 , The connecting frame 1 and the guardrail of the lifting vehicle 7 are fixed through a steel beam clamp 4. Specifically, the steel beam clamp 4 includes a steel hoop 41, a steel plate 42 and a nut 43. Among them, the steel hoop 41 is clamped outside the connecting frame 1 and the guardrail of the lifting vehicle 7. The steel plate 42 and the steel hoop 41 enclose a space for accommodating the connecting frame 1 and the guardrail of the lifting vehicle 7. The nut 43 is threadedly connected with the steel hoop 41. The steel hoop 41 passes through the steel plate 42 and is connected with the nut 43 to clamp the connecting frame 1 and the guardrail of the lifting vehicle 7.

[0050] The fixation between the connecting frame 1 and the guardrail of the lifting vehicle 7 can be realized through the steel beam clamp 4, so that the connecting frame 1 and the lifting vehicle 7 form an integral body, improving the safety performance. And when it is not needed, the steel beam clamp 4 can also be removed, so as to realize the separation between the connecting frame 1 and the lifting vehicle 7.

[0051] In some embodiments, please refer toFigure 2 , Figure 4 and Figure 5 , the connection frame 1 includes profiled steel 11, connectors 12 and fasteners 13. Among them, the quantities of the profiled steel 11, connectors 12 and fasteners 13 are not limited and can be configured according to actual situations during actual use. The connectors 12 are arranged between adjacent profiled steels 11. The fasteners 13 are arranged on the connectors 12 and are used to fix between the profiled steel 11 and the connectors 12. Multiple profiled steels 11 are spliced with each other through multiple connectors 12 to form a frame structure.

[0052] Specifically, the fasteners 13 are hexagon bolts and hexagon nuts. According to actual operation situations, the profiled steel 11 is spliced into the required frame shape, and the connectors 12 are used for connection at the splicing positions of the profiled steel 11. After passing the hexagon bolts through the profiled steel 11 and the connectors 12 and connecting them with the hexagon nuts, the profiled steels 11 are fixed together by the connectors 12 and the fasteners 13, ensuring firmness during use.

[0053] Optionally, the profiled steel 11 can be square tubes, C-shaped steels, B-shaped steels or profiles with other special-shaped cross-sections.

[0054] In some embodiments, please refer to Figure 4 and Figure 5 , the platform guardrail 3 includes a main guardrail 31, side guardrails 32 and a fixing component. Among them, the main guardrail 31 is fixedly arranged on the connection frame 1, and a notch for staff to pass through is arranged on the main guardrail 31. The side guardrails 32 are rotatably arranged on the main guardrail 31 and are used to close the notch. The fixing component is arranged on the main guardrail 31 and is used to fix the side guardrails 32.

[0055] When the staff needs to climb onto the operation platform 2, the side guardrails 32 can be opened, so that the staff can climb onto the operation platform 2 from the notch, enabling the staff not to climb over the platform guardrail 3, reducing the risk of falling and improving safety. When the staff is working on the operation platform 2, the side guardrails 32 can be closed and the fixing component can be used to fix the side guardrails 32, thereby closing the notch, making the staff safer when working on the operation platform 2, having a better protection effect and reducing the risk of falling.

[0056] In some embodiments, please refer to Figure 6 , the fixing component includes a connecting sleeve 51, a connecting column 52 and a spring 53. Among them, the connecting sleeve 51 is fixedly arranged on the side guardrail 32. The connecting column 52 is slidably arranged on the main guardrail 31. Both ends of the spring 53 are fixed to the main guardrail 31 and the connecting column 52 respectively and are used to push the connecting column 52 to extend from the main guardrail 31. When the side guardrail 32 closes the notch, the connecting column 52 is inserted into the connecting sleeve 51.

[0057] Specifically, please refer toFigure 6 On the main guardrail 31, a column pipe 313 is fixedly arranged, and a connecting column 52 is slidably arranged on the column pipe 313. A connecting block 521 is fixedly arranged at the top of the connecting column 52, and the connecting block 521 facilitates the staff to pull up the connecting column 52. One end of a spring 53 is fixedly connected to the connecting column 52, and the other end of the spring 53 is fixedly connected to the column pipe 313.

[0058] Pull up the connecting column 52 and rotate the side guardrail 32 so that the side guardrail 32 abuts against the main guardrail 31 to close the gap. At this time, the connecting column 52 and the connecting sleeve 51 are aligned. Release the connecting column 52, and the connecting column 52 extends downward under the action of the spring 53, so as to be inserted into the connecting sleeve 51 to fix the side guardrail 32.

[0059] In some embodiments, please refer to Figure 4 and Figure 5 On the main guardrail 31, a socket 311 is fixedly arranged. When the side guardrail 32 is clamped on the socket 311, the side guardrail 32 opens the gap. Specifically, the socket 311 is a plastic part with a C-shaped cross section. The side guardrail 32 includes an outer frame 321 and railings 322. Among them, the outer frame 321 is rotatably connected to the main guardrail 31, and the railings 322 are fixedly arranged on the outer frame 321.

[0060] When the side guardrail 32 is rotated to open the gap, the railings 322 can be clamped on the socket 311, so that the socket 311 fixes the side guardrail 32, preventing the side guardrail 32 from rotating randomly, and ensuring that the side guardrail 32 does not interfere with the activities of the staff when they board the operation platform 2.

[0061] In some embodiments, please refer to Figure 4 and Figure 5 A storage box 61 is hinged on the main guardrail 31, and a partition plate 611 is fixedly arranged on the storage box 61. A support rod 62 is hinged on the storage box 61. When the storage box 61 is in the unfolded and used state, the end of the support rod 62 far away from the storage box 61 is clamped on the socket 311.

[0062] Specifically, please refer to Figure 7 The support rod 62 includes a connecting portion 622 and a clamping portion 623. One end of the connecting portion 622 is hinged to the storage box 61, and the other end of the connecting portion 622 is fixedly connected to the clamping portion 623. The shape of the clamping portion 623 is cylindrical and matches the socket 311.

[0063] When operating, the staff can make the storage box 61 in a horizontal state and extend it outward from the main guardrail 31 by clamping the clamping part 623 on the card sleeve 311. At this time, the staff can place items such as tools and parts carried on them in the storage box 61, which is convenient for the staff to directly pick up. Moreover, the storage box 61 extends outward from the main guardrail 31, does not occupy the internal space surrounded by the platform guardrail 3, and does not hinder the staff from operating.

[0064] In some embodiments, please refer to Figure 7 , a first magnet 621 is fixedly arranged on the support rod 62, and a second magnet 312 is fixedly arranged on the main guardrail 31. When the storage box 61 is in the folded storage state, the first magnet 621 and the second magnet 312 adsorb each other. Specifically, the first magnet 621 is fixedly arranged on the connecting part 622.

[0065] When the staff does not need to continue operating, they can remove the clamping part 623 from the card sleeve 311, so that the storage box 61 is in a vertical state and folded on the main guardrail 31. At this time, by fitting the first magnet 621 and the second magnet 312 together, it can play a role in fixing the storage box 61, so that the storage box 61 will not rotate randomly, ensuring the stability of the storage box 61 during storage. At the same time, the staff can open the side guardrail 32 and clamp it on the card sleeve 311, so that the staff will not be hindered by the side guardrail 32 when climbing up and down.

[0066] In some embodiments, please refer to Figure 4 and Figure 5 , a hanging ring 33 for connecting with a safety hook is fixedly arranged on the platform guardrail 3. When operating, the staff can hang the safety hook of the safety belt worn on their body on the hanging ring 33, thereby further improving the safety during operation and reducing the risk of falling from a height.

[0067] All in all, compared with the prior art, for a restricted space installation platform for a lift truck provided by the present utility model, when the staff needs to operate and maintain the air duct components above the keel 81, by installing a connecting frame 1 on the guardrail of the lift truck 7, and then the staff stands on the operation platform 2. When the lift truck 7 raises the connecting frame 1, the connecting frame 1 can avoid the position of the keel 81 and pass through the installation hole 82 and rise above the keel 81, so that the staff can be lifted to the required working height and be closer to the air duct components. It is more convenient and safe for the staff to operate and maintain, and there is no need to build a flat plate at the keel 81. At the same time, the platform guardrail 3 can further protect the staff, so that when the staff operates on the operation platform 2, it is not easy to fall from the operation platform 2.
