Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, and in particular to a telescopic forked enclosure support device. Background Art

[0002] In linear construction projects such as along roads or sections, the lightweight enclosure formed by combining PVC baffles with aluminum alloy frames is difficult to effectively support only by flanges and expansion bolts due to its light weight. In order to ensure the overall stability of the enclosure, it is usually necessary to configure additional support devices on the enclosure risers.

[0003] However, most of the existing enclosure support devices are single-support diagonal rod structures, which are characterized by a support direction perpendicular to the enclosure surface and unidirectional expansion. This design performs well in a spacious construction environment, but it is difficult to arrange and install in a narrow working space or near curbs, flower beds, construction interface edges and other areas. In addition, the combination of a single support diagonal rod and an enclosure riser is weak in lateral stability. When subjected to external forces in a non-vertical enclosure direction, the support diagonal rod is difficult to effectively disperse the lateral stress, which can easily cause the cross brace of the enclosure to break, resulting in the enclosure overturning. This fracture-type failure further limits the application scenarios of the device. On the other hand, the telescopic design of the support diagonal rod generally adopts a locking structure in which the bolt directly pushes the inner rod. In the long-term repeated use of this design, the inner rod is prone to permanent deformation due to the small force point, and the friction between the bolt and the inner rod may also decrease significantly, resulting in a significant attenuation of the locking effect.

[0004] The one-way support structure used in the prior art and extending perpendicular to the enclosure surface can provide basic support functions on a wide construction site, but it is inadequate in construction scenes with narrow or complex terrain and cannot meet actual construction needs.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Reference Figure 1 and Figure 2 As shown, the present invention provides a telescopic forked enclosure 1 support device, which is used for supporting the enclosure 1 in a narrow space. The enclosure 1 plate crossbar 12 and the vertical pole 11 include: a first support assembly 2, a second support assembly 3 and a connecting assembly 4.

[0033] Specifically, the second ends of the first support assembly 2 and the second support assembly 3 are connected to the vertical pole 11 of the enclosure 1 through the connecting assembly 4, and the first support assembly 2 and the second support assembly 3 can rotate around the X-axis direction and the Y-axis direction of the connecting assembly 4, so as to realize the installation adjustment of the first support assembly 2 and the second support assembly 3, so that the first support assembly 2, the second support assembly 3 and the enclosure 1 are arranged in a triangular structure in a fixed state, and the first support assembly 2 and the second support assembly 3 can provide a large supporting force for the enclosure 1 in a narrow space through rotation adjustment, and form an independent and stable triangular support structure with the vertical pole 11 of the enclosure 1 that does not rely on the lateral support of the cross bar 12, thereby improving the supporting performance and stability.

[0034] It can be understood that the first support assembly 2 and the second support assembly 3 are both retractable structures. During the rotation of the first support assembly 2 and the second support assembly 3 around the connecting assembly 4 in the X-axis direction and the Y-axis direction, the length of the first support assembly 2 and the second support assembly 3 can be retracted and adjusted to achieve stable support and provide supporting force for the enclosure 1.

[0037] Reference Figure 3 As shown, in some embodiments of the present invention, the connecting component 4 includes a connecting plate 41, a mounting frame 42, a connecting clamping plate 43 and a first connecting shaft 44. The connecting plate 41 is fixedly connected to the vertical pole 11 by a first fastener. The mounting frame 42 is fixedly arranged on the connecting plate 41 and is located on the side away from the vertical pole 11. The connecting clamping plate 43 is rotated to be photographed on the mounting frame 42 and can be rotated around the Y-axis direction. The first connecting shaft 44 is mounted on the connecting clamping plate 43. The second end of the first support component 2 / the second support component 3 is rotatably connected to the first connecting shaft 44. The axial direction of the first connecting shaft 44 is along the X-direction. The first support component 2 / the second support component 3 can be rotated around the axial direction of the first connecting shaft 44.

[0038] In some embodiments of the present invention, the connecting plate 41 is L-shaped, the vertical pole 11 is square columnar, and the inner angle of the connecting plate 41 coincides with any outer angle of the vertical pole 11 so that the inner side surface of the connecting plate 41 fits with the two connecting end surfaces of the vertical pole 11.

[0039] Specifically, the connecting plate 41 is L-shaped, the vertical pole 11 is square columnar, the inner angle of the connecting plate 41 and the outer angle of the vertical pole 11 are both 90°, so that the inner angle of the connecting plate 41 coincides with the outer angle of the vertical pole 11, the connecting plate 41 is tightly attached to the vertical pole 11, and a first fastener is passed through the connecting plate 41 and the vertical pole 11 to fix the connecting plate 41 on the vertical pole 11, and the first fastener is a fastening bolt. A mounting frame 42 is provided at the outer corner of the connecting plate 41, and a connecting clamp plate 43 is rotatably provided on the mounting frame 42, wherein the connecting clamp plate 43 rotates around the Y-axis on the mounting frame 42, and the connecting clamp plate 43 is mounted on the first connecting shaft 44. The first support assembly 2 / the second support assembly 3 can be rotatably connected to the first connecting shaft 44 and rotate around the axial direction of the first connecting shaft 44, and the axial direction of the first connecting shaft 44 is the X-axis direction; thus, the first support assembly 2 and the second support assembly 3 are connected to the vertical pole 11 through the connecting assembly 4, thereby realizing the adjustment of the installation angle of the first support assembly 2 and the second support assembly 3, so as to be suitable for supporting the enclosure 1 in a narrow space, while ensuring strong supporting performance and improving the stability of the structure.

[0040] In some embodiments of the present invention, the mounting frame 42 includes a fixed rib 421, a mounting sleeve 422 and a second connecting shaft 423. The mounting sleeve 422 is fixedly connected to the connecting plate 41 through the fixed rib 421. The second connecting shaft 423 is passed through the mounting sleeve 422. The connecting clamp 43 is sleeved on the second connecting shaft 423. The axial direction of the second connecting shaft 423 is along the Y-axis direction. The connecting clamp 43 can rotate around the axial direction of the second connecting shaft 423.

[0041] Reference Figure 2 As shown, in some embodiments of the present invention, the first support assembly 2 includes a first telescopic rod 21 and a second telescopic rod 22 connected to each other, a first end of the first telescopic rod 21 is rotatably connected to the connecting base 5, a second end of the first telescopic rod 21 is slidably connected to a first end of the second telescopic rod 22, and a second end of the second telescopic rod 22 is rotatably connected to the connecting assembly 4;

[0042] The second supporting assembly 3 includes a third telescopic rod 31 and a fourth telescopic rod 32 connected to each other, the first end of the third telescopic rod 31 is rotatably connected to the connecting base 5, the second end of the third telescopic rod 31 is slidably connected to the first end of the fourth telescopic rod 32, and the second end of the fourth telescopic rod 32 is rotatably connected to the connecting assembly 4.

[0043] Specifically, the first telescopic rod 21 and the second telescopic rod 22 constitute the first support assembly 2, and the relative sliding of the first telescopic rod 21 and the second telescopic rod 22 realizes the telescopic adjustment of the length of the first support assembly 2. Similarly, the third telescopic rod 31 and the fourth telescopic rod 32 constitute the second support assembly 3, and the relative sliding of the third telescopic rod 31 and the fourth telescopic rod 32 realizes the telescopic adjustment of the length of the second support assembly 3.

[0044] In some embodiments of the present invention, the second ends of the first telescopic rod 21 and the third telescopic rod 31 are both provided with a limiter 6, which is suitable for limiting the sliding distance between the second telescopic rod 22 and the first telescopic rod 21, and limiting the sliding distance between the fourth telescopic rod 32 and the third telescopic rod 31.

[0045] Specifically, in order to ensure the stability of the structure and avoid changes in the lengths of the first support assembly 2 and the second support assembly 3 when the enclosure 1 is subjected to a large lateral force, a limit member 6 is set at the second end lower than the first telescopic rod and the second telescopic rod 22. By setting the limit member 6, the sliding distance between the second telescopic rod 22 and the first telescopic rod 21 is limited, and the sliding distance between the third telescopic rod 31 and the fourth telescopic rod 32 is limited, so that in a fixed state, the lengths of the first support assembly 2 and the second support assembly 3 remain unchanged to ensure the stability of the structure.

[0046] Reference Figure 4 As shown, in some embodiments of the present invention, the first telescopic rod 21, the second telescopic rod 22, the third telescopic rod 31 and the fourth telescopic rod 32 are all hollow rod structures, the first end of the second telescopic rod 22 is inserted into the first telescopic rod 21 from the second end of the first telescopic rod 21, and the first end of the fourth telescopic rod 32 is inserted into the third telescopic rod 31 from the second end of the third telescopic rod 31;

[0047] A sliding groove is provided on the first end side wall of the first telescopic rod 21 and the third telescopic rod 31, and connecting ear plates are provided on both sides of the sliding groove. The limit member 6 is passed through the connecting ear plates. The limit member 6 is suitable for adjusting the width of the sliding groove to control the sliding distance of the second telescopic rod 22 in the first telescopic rod 21 and control the sliding distance of the fourth telescopic rod 32 in the third telescopic rod 31.

[0048] Specifically, in order to facilitate the transportation of the first support assembly 2 and the second support assembly 3 and improve convenience, the first telescopic rod 21, the second telescopic rod 22, the third telescopic rod 31 and the fourth telescopic rod 32 are set to be a hollow structure, and the first telescopic rod 21, the second telescopic rod 22, the third telescopic rod 31 and the fourth telescopic rod 32 are all made of high-strength alloy materials to ensure structural strength. By inserting the first end of the second telescopic rod 22 into the hollow of the first telescopic rod 21, and inserting the first end of the fourth telescopic rod 32 into the hollow of the third telescopic rod 31 from the second end of the third telescopic rod 31, the limiter 6 realizes the insertion distance between the second telescopic rod 22 and the fourth telescopic rod 32.

[0049] It can be understood that a slide groove is opened on the side wall of the first end of the first telescopic rod 21 and the third telescopic rod 31, connecting ear plates are set on both sides of the slide groove, and the limit member 6 is passed through the connecting ear plate. By adjusting the limit member 6, the distance between the connecting ear plates on both sides of the slide groove is made close to each other, thereby reducing the width of the slide groove to clamp the second telescopic rod 22 and the fourth telescopic rod 32, thereby achieving the fixation of the length of the first support assembly 2 and the second support assembly 3.

[0050] Reference Figure 5 As shown, in some embodiments of the present invention, the connecting base 5 includes a base plate 51, two support plates 52 and a third connecting shaft 53. The base plate 51 is fixedly connected to the ground by a second fastener. The two support plates 52 are vertically arranged on the base plate 51 and are arranged at intervals. The third connecting shaft 53 is fixedly mounted on the two support plates 52. The first ends of the first support assembly 2 and the second support assembly 3 are both rotatably connected to the third connecting shaft 53, and the first support assembly 2 and the second support assembly 3 can both rotate around the axial direction of the third connecting shaft 53.

[0051] In some embodiments of the present invention, the two connecting components 4 are located in the same horizontal plane or staggered along the Y-axis direction in a fixed state.

[0052] Specifically, the first support assembly 2 and the second support assembly 3 can be provided in multiple groups, and the number of connecting assemblies 4 is equal to the total number of the first support assembly 2 and the second support assembly 3. By providing multiple groups of the first support assembly 2 and the second support assembly 3, the stability of the structure is improved.
