Description

Technical Field

[0001] This utility model relates to the field of highway bridge construction technology, and more specifically, to a waterproof fixing device for highway bridge construction. Background Technology

[0002] Rainy days often occur during road and bridge construction. If the concrete poured during construction has not fully reached the required strength, rain may reduce or damage the concrete, resulting in a waste of manpower and resources, delays in the construction period, and a reduction in the quality of the road and bridge construction.

[0003] Patent document CN221855296U discloses a waterproof fastening device for highway bridge construction, relating to the field of highway bridge construction. It includes a base plate, with support components fixedly connected to both sides of the upper surface of the base plate. A roller assembly is rotatably connected to the outer surface of the support components, and a rainproof cloth is wrapped around the outer surface of the roller assembly. A pulling component overlaps one side of the rainproof cloth. The support components include a support plate, the lower surface of which is fixedly connected to one side of the upper surface of the base plate. A cover plate is hinged to one side of the support plate. Grooves are formed in the middle of the upper surface of the support plate and the middle of the lower surface of the cover plate. A roller is rotatably connected inside the groove. This invention, through the arrangement of the support components and the roller assembly, allows the cover plate to be flipped open via the hinge, enabling simultaneous removal of the roller and the rainproof cloth. Then, the second limiting plate is unscrewed to allow for the removal and placement of the rainproof cloth, preventing uneven stress on the roller and potential damage.

[0004] Before laying tarpaulins, debris and sharp objects on the road surface should be cleared to prevent punctures and damage to the tarpaulin. However, existing waterproof fastening devices cannot clear debris from the road surface during tarpaulin laying, thus affecting work efficiency. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a waterproof fixing device for highway bridge construction, which can sweep away debris on the road surface when laying rainproof cloth, thereby improving work efficiency.

[0006] A waterproof fixing device for highway bridge construction includes a base plate with two mounting plates fixedly connected to it. A rotating plate is rotatably connected to the mounting plates. Grooves are formed on the sides of the mounting plates and the rotating plates that are close to each other. A winding shaft is rotatably installed in the grooves, and a rainproof cloth is wound on the winding shaft. The device also includes a movable plate with a clamping mechanism and a cleaning mechanism. The cleaning mechanism includes two connecting plates fixedly connected to the side of the movable plate away from the base plate. A rotating rod is rotatably connected to the two connecting plates. One end of the rotating rod is fixedly connected to the output end of a drive motor, and a hard brush is fixedly connected to the rotating rod. The lower ends of the movable plate and the connecting plates are both equipped with moving wheels.

[0007] Furthermore, the rotating plate and the mounting plate are connected by a snap fastener.

[0008] Furthermore, a fixing plate is fixedly connected to the side of the base plate away from the movable plate, and the fixing plate is fixed to the road surface by fixing bolts.

[0009] Furthermore, two columns are fixedly connected to the upper surface of the movable plate.

[0010] Furthermore, handles are fixedly attached to both the side wall of the column and the winding shaft.

[0011] Furthermore, the movable plate is provided with two sliding grooves.

[0012] Furthermore, the clamping mechanism includes two connecting blocks fixed to the side of the movable plate near the base plate, a winding rod fixed between the two connecting blocks, a slider sliding in the groove, a connecting frame fixed between the two sliders, both sliders being fixed to the arc plate, a positioning rod inserted on the connecting frame, and a positioning hole adapted to the positioning rod on the movable plate.

[0013] Furthermore, multiple positioning holes are provided at equal intervals.

[0014] Furthermore, a shielding member is fixed to the side of the two columns away from the base plate.

[0015] Furthermore, the shielding member includes an arc portion and a horizontal portion.

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

[0017] In this invention, when laying the tarpaulin, the free end of the tarpaulin is first connected to the moving plate via a clamping mechanism, and the position of the base plate is fixed by a fixing bolt. Thus, when the moving plate is dragged, the tarpaulin can be stretched for laying. Before dragging the moving plate, the drive motor is started to make the rotating rod drive the hard brush to rotate and sweep away debris on the road. During the process of dragging the moving plate forward, the hard brush rotates continuously to sweep away debris and sharp objects on the road, thereby preventing these debris and sharp objects from piercing the tarpaulin being laid behind. This allows the work of sweeping the road and laying the tarpaulin to be carried out simultaneously, improving work efficiency. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0029] like Figure 1-7 As shown, a waterproof fixing device for highway bridge construction includes a base plate 1, on which two mounting plates 2 are fixedly connected. A rotating plate 3 is rotatably connected to the mounting plates 2 via hinges. The rotating plate 3 and the mounting plates 2 are connected by a snap fastener 4. Semi-circular grooves are provided on the rotating sides of both the mounting plates 2 and the rotating plate 3. The two grooves can be joined together to form a circular groove, within which a winding shaft 5 can be rotatably mounted. A roller (a common technique in the prior art, not described in detail here) is rotatably connected within the groove to facilitate the rotation of the winding shaft 5. A rainproof cloth 6 is wound around the winding shaft 5. The device also includes a movable plate 7, on which a clamping mechanism 8 is provided. The clamping mechanism 8 is used to hold the rainproof cloth 6... The free end of the device is fixed to the movable plate 7, thereby dragging the movable plate 7 to lay the rainproof cloth 6. A sweeping mechanism 9 is provided on the side of the movable plate 7 away from the base plate 1. A fixed plate 10 is fixedly connected to the side of the base plate 1 away from the movable plate 7. The fixed plate 10 can be fixed to the road surface by fixing bolts 11 to prevent the base plate 1 from moving. The sweeping mechanism 9 includes two connecting plates 91 fixedly connected to the side of the movable plate 7 away from the base plate 1. A rotating rod 92 is rotatably connected to the two connecting plates 91. One end of the rotating rod 92 is fixedly connected to the output end of the drive motor 93 installed on either connecting plate 91. A hard brush 94 is fixedly connected to the rotating rod 92. The lower ends of the movable plate 7 and the connecting plates 91 are both equipped with movable wheels 12. When laying the tarpaulin 6, the free end of the tarpaulin 6 is first connected to the moving plate 7 by the clamping mechanism 8, and the position of the base plate 1 is fixed by the fixing bolt 11. Thus, when the moving plate 7 is dragged, the tarpaulin 6 can be stretched for laying. Before dragging the moving plate 7, the drive motor 93 is started to make the rotating rod 92 drive the hard brush 94 to rotate and sweep away the debris on the road. During the process of dragging the moving plate 7 forward, the hard brush 94 rotates continuously to sweep away the debris and sharp objects on the road, thereby preventing these debris and sharp objects from piercing the tarpaulin 6 that is being laid behind. This allows the work of sweeping the road and laying the tarpaulin 6 to be carried out simultaneously, improving work efficiency.

[0030] like Figure 1-7As shown, two columns 13 are fixedly connected to the upper end of the movable plate 7. Handles 14 are fixedly connected to the side wall of the column 13 and the winding shaft 5. The handles 14 on the winding shaft 5 make it easy for the staff to lift the winding shaft 5 and the rainproof cloth 6 wound on the winding shaft 5. The handles 14 on the column 13 make it easy for the staff to drag the movable plate 7 to lay the rainproof cloth 6.

[0031] like Figure 1-7 As shown, the movable plate 7 has two grooves 71; the clamping mechanism 8 includes two connecting blocks 81 fixedly connected to the side of the movable plate 7 near the base plate 1, and a winding rod 82 fixedly connected between the two connecting blocks 81. The winding rod 82 is used to wrap the free end of the rainproof cloth 6 around the winding rod 82. The clamping mechanism 8 also includes sliders 83 that slide in the grooves 71. The sliders 83 have an I-shaped cross-section. A connecting frame 84 is fixedly connected between the two sliders 83. The connecting frame 84 is used to synchronously drag the two sliders 83 to slide in the grooves 71. Both sliders 83 are fixedly connected to the arc plate 85. The opening of the arc plate 85 is provided with a rough surface. A positioning rod 86 is inserted into the 4, and a positioning hole 72 adapted to the lower end of the positioning rod 86 is opened on the movable plate 7. After the free end of the rainproof cloth 6 is wrapped around the winding rod 82, the connecting frame 84 is dragged so that the arc plate 85 is close to the positioning rod 86 and the rainproof cloth 6 is pressed onto the winding rod 82. Then, the positioning rod 86 is inserted into the connecting frame 84 and the lower end enters the positioning hole 72 in the appropriate position. Since the opening of the arc plate 85 is provided with a rough surface, the rainproof cloth 6 is difficult to detach from the winding rod 82 through the action of friction, thereby connecting the rainproof cloth 6 and the movable plate 7. When the movable plate 7 is dragged, the rainproof cloth 6 can be laid.

[0032] like Figure 1-7 As shown, multiple positioning holes 72 are evenly spaced, which helps staff to select the appropriate positioning hole 72 to match the positioning rod 86 according to the thickness of the rainproof cloth 6.

[0033] like Figure 1-7 As shown, a shielding member 16 is fixedly connected to the side of the two columns 13 away from the base plate 1. The shielding member 16 is used to block the debris swept away by the rotating hard brush 94. The shielding member 16 includes an arc portion 161 and a horizontal portion 162. The center of the arc of the arc portion 161 is located on the central axis of the rotating rod 92. The arc portion 161 is used to block the debris swept away by the hard brush 94. The horizontal portion 162 is parallel to the road surface and is at least five centimeters away from the road surface. In this embodiment, the lower end face of the horizontal portion 162 is five centimeters away from the road surface. The horizontal portion 162 is set to block part of the debris swept away by the hard brush 94.

[0034] The drive motor 93 is electrically connected to an external power supply and to a control unit (not shown in the figure).

[0035] The working principle of a waterproof fixing device for highway bridge construction in this embodiment is as follows: When laying the rainproof cloth 6, the free end of the rainproof cloth 6 is first wrapped around the winding rod 82. The connecting frame 84 is dragged so that the arc plate 85 is close to the positioning rod 86 and the rainproof cloth 6 is pressed onto the winding rod 82. Then, the positioning rod 86 is inserted into the connecting frame 84 and the lower end enters the positioning hole 72 in the appropriate position. The position of the base plate 1 is fixed by the fixing bolt 11. Thus, when the moving plate 7 is dragged, the rainproof cloth 6 can be stretched for laying. Before the moving plate 7 is dragged, the drive motor 93 is started so that the rotating rod 92 drives the hard brush 94 to rotate and sweep away the debris on the road surface. During the process of dragging the moving plate 7 forward, the hard brush 94 rotates continuously to sweep away the debris and sharp objects on the road surface, thereby preventing these debris and sharp objects from piercing the rainproof cloth 6 that is being laid behind. This allows the work of sweeping the road surface and laying the rainproof cloth 6 to be carried out simultaneously, improving work efficiency.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
