[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0019] like Figures 1 to 4In one embodiment of the portable fixing device for waterside operation of the utility model, it is detachably mounted on a stable curbstone, and includes a U-shaped frame 1 matched with the curbstone; the U-shaped frame 1 includes two inner plates 11 and outer plates 12 respectively arranged on both sides of the curbstone, and a top plate 13 connecting the inner plates 11 and the outer plates 12; the inner plate 11 is arranged on the side close to the construction area, and the outer plate 12 is arranged on the side away from the construction area; the outer plate 12 is hinged with two clamping members 2 for swinging and clamping the curbstone; the clamping member 2 is a folding rod design; and the clamping member 2 is provided with a fixing hole 23 for fixing a safety rope. By inserting the U-shaped frame on the top of the curbstone and cooperating with the folding rod type clamping member for fixing the safety rope, the deadweight of the staff is utilized, and the two inner plates and outer plates clamped on both sides of the curbstone are cooperated to form a stable friction clamping of the curbstone, so as to ensure the stable fixation of the safety rope of the construction staff, and ensure the safe construction of the staff while reducing the labor force, reduce the construction manpower demand, and improve the work efficiency.

[0020] Specifically, the clamping member 2 includes a hinge shaft 21 hinged on the outer plate 12, an extrusion plate 24 and a positioning rod 22 fixed on both sides of the hinge shaft 21; the extrusion plate 24 is arranged on the side of the hinge shaft 21 close to the top plate 13; the positioning rod 22 is arranged to be inclined downward away from the inner plate 11; and the fixing hole 23 is arranged at the overhanging end of the positioning rod 22. The inclined positioning rod cooperates with the extrusion plate arranged at the end of the positioning rod and the fixed safety rope to form a downward pressure on the U-shaped frame, and drives the clamping member to rotate around the hinge shaft to form a clamping force on the curbstone, effectively realizing the stable clamping of the equipment on the curbstone, ensuring stable fixation, and forming a stable clamping.

[0021] Specifically, a side of the extrusion plate 24 close to the inner plate 11 is provided with a rough rubber friction surface.

[0022] Specifically, the angle between the positioning rod 22 and the extrusion plate 24 is 130° to 140°.

[0023] Specifically, a friction block 3 is provided on the inner wall of the inner plate 11 ; the friction block 3 is of a trapezoidal design with a cross section increasing from top to bottom; the friction block 3 is made of rubber; and a rough friction surface is provided on the side of the friction block 3 away from the inner plate 11 .

[0024] Specifically, at least two handles 4 are provided on the top of the top plate 13 .

[0025] Specifically, the distance between the two clamping members 2 is greater than 1 / 2 of the length of the top plate 13 .

[0026] Working principle: the staff looks for a stable and solid curbstone at the top of the open channel near the construction area, inserts the U-shaped frame 1 from the top of the curbstone, sets the inner plate 11 on the side of the curbstone close to the construction area, and sets the outer plate 12 on the side of the curbstone away from the construction area. After the inner wall of the top plate 13 is close to the top surface of the curbstone, fix the two safety ropes on the fixing holes 23 of the two clamping parts 2 respectively, and wrap the other end of the safety rope around the safety buckle of the operator. After the staff moves to the clearly inclined working area, the staff tightens the safety rope by their own weight, driving the clamping part 2 to rotate around the hinge shaft 21 toward the inner plate 11. The extrusion plate 24 set on the upper part of the outer plate 12 cooperates with the trapezoidal friction block 3 on the inner plate 11 to form a stable clamp on the curbstone, which effectively ensures the safety of the staff, reduces the labor demand of the staff, improves work efficiency, and increases work safety.
