Detailed implementation manners

[0022] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.

[0023] As Figures 1-6 shown, a detection, maintenance and reinforcement device for an existing bridge includes two support frames 1. The support frames 1 are arranged in a U shape. A plurality of cross beams 2 are fixedly connected between the two support frames 1. A top plate 3 is fixedly connected at the corner between the two support frames 1. An adjustment component is arranged on the top plate 3. Limit grooves 8 are respectively opened on the opposite side walls of the support frames 1. A moving component is arranged in the limit grooves 8. A transition beam 13 is fixedly connected to the bottom end of the support frame 1. A maintenance hanging basket 14 is fixedly connected to the side wall of the transition beam 13. The rear side of the maintenance hanging basket 14 is open. A baffle 15 is rotatably connected to the rear side wall of the maintenance hanging basket 14 near the bottom. A shading net 17 is assembled on the baffle 15. A protection component is arranged on the side wall of the baffle 15.

[0024] Among them, in the maintenance hanging basket 14 of this solution, no steel mesh or protection net is placed. In actual use, a metal mesh can be installed at the bottom surface and side wall positions of the maintenance hanging basket 14 to reduce the gap, prevent maintenance tools from falling, and further improve its safety performance.

[0025] As Figure 1 and Figure 4 shown, the adjustment component includes a screw sleeve 4 fixedly connected to the top surface of the top plate 3. The screw sleeve 4 penetrates through the top plate 3. A screw rod 5 is threadedly connected in the screw sleeve 4. The top end of the screw rod 5 is fixedly connected with a runner 6. The bottom end of the screw rod 5 is assembled with a movable wheel 7.

[0026] Among them, since the fence heights on different bridges are different, in order to improve the application range of this device, the height of the movable wheel 7 can be adjusted to adapt to fences of different heights. At the same time, the movable wheel 7 is also used to drive the maintenance hanging basket 14 to move, thereby improving its practicability.

[0027] As Figure 3 and Figure 5As shown, the movable assembly includes a movable plate 9 movably connected in the limiting groove 8, the side wall of the movable plate 9 is equipped with a guide wheel 10, the side wall of the movable plate 9 is movably connected with two bolts 11, the side wall of the limiting groove 8 is provided with a plurality of screw holes 12, and the bolts 11 are threadedly connected with the screw holes 12.

[0028] Specifically, it can be seen from the description of this solution that the movable plate 9 is detachable. In actual use, the thickness of the movable plate 9 and the diameter of the guide wheel 10 can be set to various specifications. The appropriate movable plate 9 is selected according to the thickness of the bridge fence and the side of the bridge, and is fixed in the limit groove 8 by bolts 11, so that the guide wheel 10 can be used to offset the fence, thereby positioning and moving the maintenance basket 14 and increasing stability during use.

[0029] like Figure 2 and Figure 3 As shown, the protective assembly includes two arc plates 20 fixedly connected to the side wall of the baffle 15, and a storage groove is opened on the side wall of the maintenance basket 14. The arc plate 20 is adapted to the storage groove. Two traction ropes 16 are fixedly connected between the maintenance basket 14 and the baffle 15, and locking parts are provided on the side wall of the baffle 15 near the corners.

[0030] The locking member includes a screw 21 threadedly connected to the side wall of the baffle 15 , and two locking blocks 22 are fixedly connected to the side wall of the maintenance hanging basket 14 , and the screw 21 is threadedly connected to the locking blocks 22 .

[0031] Specifically, the traction rope 16 can adopt a high-strength structure such as steel wire and chain, which can provide sufficient supporting force for the baffle 15, so that when the maintenance personnel stand on the baffle 15, there will be no large shaking. In addition, when the baffle 15 is lowered, the arc plate 20 will immediately unfold to cover both sides of the baffle 15, providing a sense of security for the maintenance personnel and facilitating the maintenance personnel's support.

[0032] like Figure 6 As shown, the baffle plate 15 and the side wall of the arc-shaped plate 20 are respectively fixedly connected with a hanging rod 19 , and the side wall of the shielding net 17 is fixedly connected with a hook 18 , and the hook 18 is matched with the hanging rod 19 .

[0033] Among them, the hooks 18 are all lockable hooks 18, which can be disassembled or replaced in a fixed position according to actual needs during use; in addition, the shielding net 17 can be made of materials such as metal net or plastic net, which is no longer specifically limited in this solution and can be selected according to actual needs.

[0034] The working principle of the utility model is as follows: firstly, the extension distance of the movable wheel 7 is adjusted according to the height of the bridge fence, the rotating wheel 6 is rotated to drive the screw 5 to rotate, and the screw 5 drives the movable wheel 7 to move downward to a suitable position, and then the support frame 1 is clamped on the fence, and the bolt 11 is loosened to adjust the position of the guide wheel 10, so that the guide wheel 10 can be against the bridge maintenance or the side of the bridge, so that the support frame 1 is stressed. After that, the maintenance personnel can enter the maintenance hanging basket 14 through the crossbeam 2 as a ladder. When the maintenance personnel need to expand the maintenance hanging basket 14, the screws 21 can be loosened to disengage the locking block 22, and the fixation of the baffle 15 can be released. Then the baffle 15 can be lowered, and the arc plate 20 can shield the two sides of the baffle 15 at the same time. The baffle 15 can be reinforced by the traction rope 16 so that the baffle 15 is in a horizontal state to expand the space of the maintenance basket 14. Then the shielding net 17 is hung on the hanging rod 19 through the hook 18 to protect the baffle 15, increase the safety of the maintenance basket 14, and facilitate maintenance personnel to maintain the bridge.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
