Description

Technical Field

[0001] This utility model relates to the field of power industry maintenance and safety measure arrangement technology, specifically to a multi-purpose foldable wheeled vertical sign device. Background Technology

[0002] Currently, when carrying out maintenance work on generator units and other equipment in power plants and substations, it is necessary to place various types of vertical signs in designated locations to separate the maintenance area from the live area. This serves to prevent workers from going to the wrong equipment area and to protect the safety of personnel and equipment. These signs typically consist of two parts: a support frame and the main body of the sign.

[0003] However, the current signs are large in size, heavy in weight and of many types, which makes them inconvenient to transport and store. The safety measures for setting up and removing them are also time-consuming. Before transporting them, it is necessary to identify the types of signs required for different locations based on the drawings and take them out one by one, which is time-consuming and labor-intensive. To address this, we have proposed a multi-purpose foldable wheeled vertical sign device. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-purpose foldable wheeled vertical signage device to address the above-mentioned problems. It allows for convenient movement of vertical signs to designated locations without prior identification or screening, solving the problems of inconvenient handling and storage of vertical signs, time-consuming safety measures for placement and removal, and the need to identify the types of signs required for different locations based on drawings and remove them one by one before handling.

[0005] The technical solution of this utility model is as follows:

[0006] A multi-purpose foldable wheeled upright signage device includes a lettering main structure, a front support rod, and a bottom support rod. The bottom support rod is connected to the front support rod via a hinge, and the front support rod clamps and fixes the lettering main structure from both sides. A signage support rod is also hinged to the middle of the front support rod, and the front support rod is provided with a storage groove, while the bottom support rod is provided with a slot. When the signage support rod is unfolded, its lower end can be locked into the slot for fixation; when the signage support rod is folded, it can be folded into the groove.

[0007] The above structure solves the problems of inconvenient handling and storage of vertical signs, and the time-consuming installation and removal of safety measures.

[0008] Furthermore, the length of the sign support rod is equal to the length of the groove; a limit block is provided on the sign support rod, which can be locked into the groove when the sign support rod is folded.

[0009] The above structure allows the sign support rod to be locked into the slot when folded, resulting in a smaller space occupied by the device after folding and improving the utilization rate of storage space.

[0010] Furthermore, an upper scroll and a lower scroll are provided at the top and bottom edges of the main body of the lettering, and scroll unfolding and fixing devices are provided on both sides of the main body of the lettering.

[0011] The above structure solves the problem in the prior art that it is necessary to identify the types of signs required for different locations based on drawings and remove them one by one before handling.

[0012] Furthermore, the scroll unfolding and fixing device is an L-shaped buckle structure. The horizontal end of the scroll unfolding and fixing device is fixed to the side of the main body of the lettering, and the vertical end is provided with a limiting groove that matches the ends of the upper and lower scrolls.

[0013] The above structure, with its L-shaped buckle and limiting groove, prevents the scroll from shaking.

[0014] Furthermore, the bottom of the bottom support rod is equipped with four omnidirectional wheels with brakes. The omnidirectional wheels are polyurethane-edged omnidirectional wheels with a wheel diameter of 80-100mm and a load-bearing capacity of ≥50kg.

[0015] The aforementioned structure allows the omnidirectional wheels to move the device in various directions. The use of polyurethane-coated omnidirectional wheels extends their lifespan.

[0016] Furthermore, the slot is a U-shaped stainless steel card holder with a rubber anti-slip pad layer attached to the inner wall; the hinge is a stainless steel hinge with a rust-proof skin sealing layer covering the outer part of its rotating shaft.

[0017] Through the above structure, the rubber anti-slip pad layer enhances the fixing stability of the limiting block and solves the problem of accidental disengagement during folding.

[0018] Furthermore, the sign support rod is a telescopic sleeve structure with a length adjustment range of 600-900mm.

[0019] The above structure, using a telescopic sleeve structure, can adapt to uneven ground.

[0020] Furthermore, the upper and lower scrolls are detachably connected to the main structure of the lettering via magnetic clasps, and the lettering panel is a PVC-coated printed board.

[0021] With the above structure, the magnetic plate enables quick replacement of text. This device can change the displayed text according to the needs of the sign, so that the upper scroll is not only marked "Working Here" and the lower scroll is not only marked "Under Maintenance".

[0022] Furthermore, the bottom support rod has a folding angle of 0°-90°, and the overall thickness after folding is ≤150mm.

[0023] Furthermore, the frame of the main structure of the lettering is made of anodized aluminum alloy, and the interior is filled with honeycomb paper core material to reduce weight.

[0024] With the above structure, the use of honeycomb paper core and aluminum alloy frame makes the overall weight less than 8kg.

[0025] Compared with existing technologies, the beneficial effects of this utility model are:

[0026] 1. The design is reasonable and the structure is simple and practical, facilitating the installation of safety measures for the neutral signage during maintenance;

[0027] 2. Compared with traditional freestanding signs, new bottom casters have been added to improve the ease of handling;

[0028] 3. Compared with traditional freestanding signs, the addition of a folding structure reduces the space occupied when folded, thus improving the utilization of storage space;

[0029] 4. Compared with traditional freestanding signs, the three types of sign text are combined into one main body, eliminating the need for categorization during storage and selection when needed, thus improving the efficiency of retrieval and storage. Attached Figure Description

The bottom support rod 6 is connected to the front support rod 5 via a hinge. The front support rod 5 clamps and fixes the main lettering structure 1 from both sides. A sign support rod 10 is also hinged to the middle of the front support rod 5. The front support rod 5 also has a storage groove 12, and the bottom support rod 6 has a slot 9. When the sign support rod 10 is unfolded, its lower end can be locked into the slot 9 for fixation. When the sign support rod 10 is folded, it can be stored in the groove 12. An upper scroll 3 and a lower scroll 4 are provided at the top and bottom edges of the main lettering structure 1, and scroll unfolding and fixing devices 2 are provided on both sides of the main lettering structure 1. The upper scroll 3 and the lower scroll 4 are detachably connected to the main lettering structure 1 via magnetic clasps. The lettering panel is a PVC-coated printed board. Figure 3 and Figure 4 As shown, the upper scroll has the words "Working here" and the lower scroll has the words "Under maintenance". The main structure 1 of the text has the word "Transport".

[0040] The device integrates three types of labels—"Transport," "Working Here," and "Under Maintenance"—into a single unit, eliminating the need to sort and transport multiple types of labels and significantly improving the efficiency of safety measure deployment.

[0041] like Figure 5 and Figure 6As shown, the length of the sign support rod 10 is equal to the length of the groove 12; a limit block 11 is provided on the sign support rod 10, and the limit block 11 can be snapped into the card slot 9 for fixation when the sign support rod 10 is folded. The sign support rod 10 can be folded and stored in the groove 12. The bottom support rod 6 is folded by hinge, and is limited and fixed in cooperation with the card slot 9. After folding, the volume is reduced by more than 50%, improving the utilization rate of the storage space. When unfolding, only need to snap the sign support rod 10 into the card slot 9 and pull out the reel for fixation; when storing, operate in the reverse direction, and a single person can complete the deployment or recovery within 1 minute.

[0042] The reel unfolding and fixing device 2 is an L-shaped buckle structure. The horizontal end of the reel unfolding and fixing device 2 is fixed to the side of the word main body structure 1, and the vertical end is provided with limit slots matching the ends of the upper reel 3 and the lower reel 4.

[0045] The sign support rod 10 is a telescopic sleeve structure, and the length adjustment range is 600 - 900 mm.

[0046] Working principle: When taking the vertical sign, there is no need to deliberately identify the required words. After moving it to the required position, step on the brake brake 8 to fix the four universal wheels 7 under the bottom support rod, and pull the limit block 11 on the sign support rod 10 to make the lower end of the sign support rod 10 snap into the card slot 9 on the bottom support rod 6, then the word main body structure 1 of the sign can be fixed. According to the required words, when the word "transport" is needed, make the word main body structure 1 on the top; when the words "working here" are needed, pull out the upper reel 3 and make its lower end snap under the reel unfolding and fixing device 2; when the words "under maintenance" are needed, pull out the lower reel 4 and make its upper end snap above the reel unfolding and fixing device 2. When storing, put the sign support rod 10 into the groove 12 on the back of the front support rod, and then fold the bottom support rod 6 to make the limit block 11 on the sign support rod 10 snap into the card slot 9 on the bottom support rod 6, then the occupied space can be reduced for storage.

[0047] Compared to traditional freestanding signs, the newly added bottom casters improve the ease of handling; the new folding structure improves storage space utilization by reducing the space occupied when folded; and the original three types of sign text are integrated into one main body, eliminating the need for separate organization when storing and eliminating the need for selection when retrieving, thus improving the efficiency of retrieval and storage.
