[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The support mechanism of this application enables the equipment to be assembled and disassembled quickly and stably, thereby improving construction efficiency and reducing labor intensity. The base frame is equipped with a rotating adjustment seat, and the columns are plugged into the adjustment seat. All components are detachably connected.

A column 45 is inserted into the inner wall of the connecting groove 44. Wedges 46 are bolted to both sides of the inner wall of the column 45. Fixing holes 47 are provided through the two sides of the adjusting seat 43. The middle of the inner wall of the mounting groove 41 is fixedly connected to both ends of the connecting shaft 42. The outer wall of the connecting shaft 42 is rotatably connected to the inner wall of the adjusting seat 43. The connecting groove 44 and the column 45 are both I-shaped. The column 45 has the same hole at one end corresponding to the adjusting seat 43.

[0027] Please see Figure 1 , Figure 3 and Figure 4 The support mechanism 7 includes a slide rail 71, one side of which is fixedly connected to one side of the column 45. A limit hole 72 is provided on one side of the slide rail 71. A movable seat 73 is provided on the outer wall of the slide rail 71. A limit bolt 74 is threadedly connected to the middle of the movable seat 73. A connector 75 is rotatably connected to the inner wall of the movable seat 73. A telescopic rod 76 is fixedly connected to one side of the connector 75. A threaded hole 77 is embedded in the inner wall of the telescopic rod 76. A slip ring 78 is fixedly connected to one outer wall of the telescopic rod 76. A support cylinder 79 is slidably connected to the outer wall of the telescopic rod 76. The inner walls of the cylinder 79 are fitted with displacement cavities 710 on both sides. The inner wall of the threaded hole 77 is threaded with a screw 711. A double-headed motor 712 is fixedly connected to the middle of the inner cavity of the support cylinder 79. A pneumatic cylinder 713 is hinged to the lower end of the telescopic rod 76. One side of the slide rail 71 is fitted with the outer wall of the limiting hole 72. The outer side of the slide rail 71 is slidably connected to the inner wall of the movable seat 73. The telescopic end of the pneumatic cylinder 713 is hinged to the lower end face of the telescopic rod 76. The lower end of the pneumatic cylinder 713 is also hinged to one side of the column 45. The outer diameter of the slip ring 78 is the same as the inner diameter of the displacement cavity 710.

[0028] Working principle: First, fixing holes 47 are provided on the adjusting seat 43, and wedges 46 can be symmetrically distributed along both sides of the inner wall of the column 45 to achieve the fastening effect on the support plate 5. The wedges 46 are bolted to the column 45. The wedges 46 are installed at intervals on the inner side of the column 45 and fixed to the column 45 with bolts. The two ends of the support plate 5 are inserted into the grooves formed by the corresponding wedges 46 and locked in place. This allows the support plate 5 to be fixed and its position adjusted according to actual needs. This design not only improves the adaptability of the support device but also ensures that the support device can be used under different working conditions. In addition to ensuring stability and safety, the I-shaped connecting groove 44 and column 45 structure increase the strength and rigidity of the device, making the entire support mechanism 4 more stable under pressure and effectively preventing deformation and damage. Through this structural design, the support mechanism 7 can achieve precise adjustment and stable support of the support plate 5. The use of the dual-head motor 712 allows the telescopic rods 76 on both sides of the support cylinder 79 to extend and retract quickly, thereby rapidly adjusting the position and angle of the support plate 5 to adapt to different construction needs. The addition of the pneumatic cylinder 713 provides the support mechanism 7 with extra stability and force, ensuring the support cylinder can withstand heavy loads. The stability of support plate 5 and the cooperation between telescopic rod 76 and slip ring 78 ensure that telescopic rod 76 can move smoothly within displacement cavity 710. Meanwhile, the setting of limit bolt 74 and limit hole 72 ensures the adjustment of the height position of support cylinder 79, preventing structural damage caused by excessive extension and retraction. The operator starts the dual-head motor 712, which drives the screw 711 to rotate. When the screw 711 rotates, it drives the telescopic rod 76 to move horizontally along the internal threaded hole 77. The slip ring 78 further stabilizes the movement of the telescopic rod 76. At this time, the telescopic rods 76 on both sides of support cylinder 79 extend outwards. The telescopic rod 76 extends and tilts the slide rail 71 and the column 45 relative to each other, making it suitable for use in different rectangular culverts. The slot 2 and the locking block 6 allow for the installation of multiple support plates 5, which are easy to disassemble and quick to install. The pneumatic cylinder 713 also extends and retracts accordingly, allowing the position of the movable seat 73 on the slide rail 71 to be adjusted according to the height of the rectangular culvert. The column 45 is inserted into the support plate 5, which easily ensures the stability of the entire support device, avoids the enlargement of the joint, and provides good support performance. The telescopic rod 76 and the pneumatic cylinder 713 not only support the support mechanism 7, but also work with the movable seat 73 to adjust the height of the support mechanism 7.
