DETAILED DESCRIPTION

[0024] The embodiment of the present application will be described in detail below with the aid of drawings and examples, so that the realization process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented.

[0025] Embodiment, such as Figures 1-5As shown, a kind of off-site protection device for road bridge engineering construction, including multiple groups first protection plate 1, second protection plate 101, first protection plate 1 and second protection plate 101 relative two sides are slidably connected with first connecting rod 2 and second connecting rod 201, first protection plate 1 and second protection plate 101 relative two sides are all set with the slide rail 4 of first connecting rod 2 and second connecting rod 201 sliding, slide rail 4 is set with multiple limiting screw grooves 5 for the position limiting of first connecting rod 2 and second connecting rod 201, each first connecting rod 2 and second connecting rod 201 are all threadedly connected with limiting screw 6, by being provided with first connecting rod 2 and second connecting rod 201 on the front and back of first protection plate 1 and second protection plate 101, multiple groups first protection plate 1 can be connected with second protection plate 101 by first connecting rod 2 and second connecting rod 201, and first protection plate 1 and second protection plate 101 can also be folded by first connecting rod 2 and second connecting rod 201, so that the installation of first protection plate 1 and second protection plate 101 is more convenient for construction personnel, and when first protection plate 1 and second protection plate 101 are stored, multiple guardrails need not be bound by binding again, so that construction personnel can install and store first protection plate 1 and second protection plate 101 conveniently;

[0026] It should be noted that each first protection plate 1 and second protection plate 101 is a group, for example: first protection plate 1 = second protection plate 101 = first protection plate 1 = second protection plate 101....Here, = instead of first connecting rod 2 and second connecting rod 201;

[0027] When multiple groups first protection plate 1 and second protection plate 101 need to be supported, construction personnel pull first protection plate 1 or second protection plate 101 to separate and stand, and then adjust first connecting rod 2 and second connecting rod 201 to make first protection plate 1 and second protection plate 101 be in suitable position, then twist limiting screw 6, so that first connecting rod 2 and second connecting rod 201 can be limited on slide rail 4, to avoid that first connecting rod 2 or second connecting rod 201 slides when being used;

[0028] When multiple groups first protection plate 1 and second protection plate 101 need to be stored, construction personnel can fold first connecting rod 2 and second connecting rod 201 and clamp into the inside of slide rail 4 Figure 3 Then, one side of first protection plate 1 and second protection plate 101 is coincident and placed, so that the storage of multiple groups first protection plate 1 and second protection plate 101 can be completed.

[0029] A folding mechanism is provided between the first link 2 and the second link 201. The folding mechanism is used to fold multiple sets of first protective plates 1 and second protective plates 101. The folding mechanism includes a fixed rod 8 fixedly set at one end of the first link 2, a rotating shaft 9 rotatably connected to the fixed rod 8, and a connecting rotating rod 10 rotatably connected to the rotating shaft 9. Both the upper and lower ends of the connecting rotating rod 10 are fixedly connected to the second link 201. Through the folding mechanism, the construction personnel can complete the above-mentioned storage of the first protective plate 1 and the second protective plate 101.

[0030] When the first link 2 and the second link 201 need to be folded, the first link 2 and the second link 201 are folded by the rotational connection of the pivot 9 and the fixed rod 8. Then, the first link 2 and the second link 201 can be further folded by the rotational connection of the pivot 9 and the connecting pivot 10. In this way, one side of the first link 2 and one side of the second link 201 can come into contact, thereby completing the folding.

[0031] like Figure 1 , Figure 5 As shown, each of the first connecting rods 2 and the second connecting rod 201 is further provided with a connecting screw groove 11. The limiting screw 6 is threadedly screwed into the connecting screw groove 11. The length of the limiting screw 6 is longer than that of the connecting screw groove 11. One end of the limiting screw 6 extends into the limiting screw groove 5 and is threadedly screwed into it. A screw rod 12 is fixedly provided at one end of the limiting screw 6. By threading the limiting screw 6 into the connecting screw groove 11, when the construction personnel need to slide and limit the first connecting rod 2 and the second connecting rod 201, the limiting screw 6 is screwed into the limiting screw groove 5 by the screw rod 12, so that the limiting screw 6 gradually moves to one side of the limiting screw groove 5 and is threadedly screwed into the limiting screw groove 5. In this way, the sliding and limiting of the first connecting rod 2 and the second connecting rod 201 can be completed.

[0032] like Figure 1 , Figure 5 As shown, furthermore, each slide rail 4 has a sliding seat 3 slidably connected inside. The first link 2 and the second link 201 are rotatably connected to the sliding seat 3 through the connecting rotating rod 13. The connecting rotating rod 13 is fixedly connected to the first link 2 and the second link 201 respectively. The first link 2 and the second link 201 are slidably connected to the slide rail 4 through the sliding seat 3. At the same time, the first link 2 and the second link 201 rotate through the connecting rotating rod 13 and the sliding seat 3. This allows for a wider adjustment angle of the first link 2 and the second link 201, so as to cooperate with the folding mechanism.

[0033] like Figure 3Further, each slide rail 4 is provided with a limiting slide rail 7 on opposite sides, and the slide seat 3 is provided with a limiting slide block 301 on opposite sides and in sliding connection with the limiting slide rail 7, so that the slide seat 3 is in sliding connection with the limiting slide rail 7 through the limiting slide block 301, and the slide seat 3 and the slide rail 4 are prevented from being derailed.

[0034] It should be noted that the slide rail 4 is a through slot, so that the first guard plates 1 and the second guard plates 101 can be in a straight line when in use.

[0037] When a plurality of first guard plates 1 and second guard plates 101 need to be supported, the construction personnel pull the first guard plates 1 or the second guard plates 101 to separate and stand them, then adjust the first connecting rods 2 and the second connecting rods 201 to make the first guard plates 1 and the second guard plates 101 be in a suitable position, and then twist the limiting screw 6 to limit the first connecting rods 2 and the second connecting rods 201 on the slide rail 4, so that the first connecting rods 2 or the second connecting rods 201 are prevented from sliding when in use.

[0038] When a plurality of first guard plates 1 and second guard plates 101 need to be stored, the construction personnel can fold the first connecting rods 2 and the second connecting rods 201 and clamp them into the slide rail 4, as shown in the drawings, Figure 3 and then make one side of the first guard plates 1 and the second guard plates 101 coincide and be placed, so that the storage of the plurality of first guard plates 1 and the second guard plates 101 is completed.
