technical field

The utility model relates to the technical field of construction devices, in particular to a position-limiting vehicle used for position-limiting steel strands.

Background technique

In recent years, my country's bridge construction technology has developed rapidly, and prestressed construction has been widely used in bridge construction. As prestressed construction has become more common, the demand for steel strands has gradually increased. At present, during the unpacking construction process of the steel strand reel, the operation is very irregular. During the construction, steel pipe fasteners and other construction site materials are often used to limit the unpacking of the steel strand, resulting in internal steel strands in the steel strand during use. The potential safety hazard of collapsing bombs. At the same time, the limit tool is made of materials on the construction site, which is extremely irregular. In addition, the inconsistency of the steel strand limit tools makes it difficult to cover the steel strands placed on the construction site in rainy days, and the steel strands are prone to corrosion.

Further, the end frame is a square frame structure composed of upper and lower horizontal frames and left and right mullions, and an adjustment hole is provided at the upper and lower parts of the mullion respectively; The four adjustment holes of the end frames arranged in parallel are connected to form the limit frame.

Further, the adjustment hole is an oblong hole, the cross bar is set through the adjustment hole, connected with the end frame through a threaded connection, and can be placed in the adjustment hole when the threaded connection is loosened. sliding, and can be fixed with the end frame after the threaded connector is tightened.

Further, two circular rings formed by bending round steel are set concentrically, and are connected and fixed by four evenly distributed connecting rods to form a limiting port, which is located in the middle of the end frame, and is connected and fixed by connecting rods. It is fixed with the end frame; the diameter of the ring away from the end frame is smaller than that of the ring close to the end frame.

Further, hoisting holes are provided at both ends of the side frame.

The utility model provides an easy-to-detachable steel strand unwinding and limiting car, which has the following beneficial effects:

1. The end of the steel strand is led out from the limit port and used from the inside of the wire harness. The unpacking design is reasonable, which eliminates the safety hazard of the steel strand inside the steel strand being collapsed;

2. By adjusting the position of the limit card installed on the end frame and the adjusting cross bar in the adjusting hole to adapt to the length and diameter of the steel strand bundle, it has a wide range of applications and good practicability;

3. The setting of the limit port reduces the swing range of the steel strand after unpacking, and at the same time avoids direct friction with the end frame of the limit frame when the steel strand is drawn out after the steel strand bundle has been used to a certain extent, so that the steel strand The thread extraction is more labor-saving and convenient.

4. The side frame is supported by a bracket to connect the rainproof cloth roll, which can be unfolded in rainy weather to cover the steel strand and avoid its corrosion;

5. The hoisting hole is used to thread the rope to drag the limit car through the universal wheel or perform hoisting, which saves effort to realize the movement of the limit car.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are Some embodiments of the utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1 to 2, the structural relationship is as follows: it includes a limit frame 2 for limiting the steel strand bundle 3 and a base structure for supporting and fixing the limit frame 2, and each bottom beam 12 is parallel and evenly distributed. It is connected between two side frames 11 arranged in parallel, and universal wheels 16 are arranged at both ends of the lower surface of the side frame 11 to form a base structure, and each limit card 15 is arranged on both ends of the upper surface of the side frame 11 for positioning Limiting frame 2 carries out spacing; Two supports 13 are respectively positioned at the outsides of each limit card 15 at the two ends of the same side frame 11, are fixed on the side frame 11, and are used to support and connect rainproof cloth roll 14; On the base structure, the steel strand bundle 3 is limited in the limit frame 2.

Preferably, the end frame 21 is a square frame structure composed of upper and lower horizontal frames and left and right vertical frames, and an adjustment hole 24 is respectively provided at the upper and lower parts of the vertical frame; the two ends of the four horizontal bars 22 are respectively It is connected with four adjustment holes 24 of two end frames 21 arranged in parallel to form a limiting frame 2 .

Preferably, the adjustment hole 24 is an oblong hole, and the cross bar 22 is set through the adjustment hole, and is connected with the end frame 21 through a threaded connection, and can slide in the adjustment hole 24 when the threaded connection is loosened, and can be placed on the threaded connection. After fastening, it is fixed with the end frame 21.

Preferably, two circular rings bent and formed by round steel are concentrically arranged, and are connected and fixed by four evenly distributed connecting rods to form a limit port 23, which is located in the middle of the end frame 21, and is connected to the end frame 21 through the connecting rod.
