[0002] Prefabricated U-shaped concrete drain troughs are difficult to hoist due to their heavy weight. Currently, the main hoisting methods include clamp hoisting, rope binding hoisting, and hoisting with hoisting holes. Clamp hoisting, such as clamp hoisting, often leaves scratches on the concrete surface, and the installation and disassembly of the clamp is generally complicated and cumbersome; rope binding hoisting cannot ensure the balance of hoisting, and the hoisting process is prone to tilting, which is unsafe; and hoisting with hoisting holes will destroy the overall structure of the U-shaped concrete drain trough, causing quality risks. Therefore, a fast and safe hoisting tool is needed to hoist the prefabricated U-shaped concrete drain trough. Summary of the invention

A lifting hole is provided on the side of the extrusion facing the inside of the U-shaped concrete drain trough, and a lifting rope is tied to the lifting hole. The side of the extrusion away from the inside of the U-shaped concrete drain trough is an upturned elbow, and the horizontal distance between the outermost end of the elbow and the transverse connecting rod is greater than the horizontal distance between the inner wall of the U-shaped concrete drain trough and the transverse connecting rod.

[0007] Preferably, the length of the transverse connecting rod is 3-5 cm shorter than the length of the U-shaped concrete drainage trough.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] This embodiment includes two parallel transverse connecting rods 1, which are located inside the U-shaped concrete drainage trough. The transverse connecting rods 1 are placed along the length direction of the U-shaped concrete drainage trough, and the length of the transverse connecting rods 1 is 3-5 cm shorter than the length of the U-shaped concrete drainage trough. The horizontal distance between the two transverse connecting rods 1 is less than the inner width of the U-shaped concrete drainage trough, that is, there is a certain distance between the transverse connecting rods 1 and the inner wall of the U-shaped concrete drainage trough on the same side. The two ends of the two transverse connecting rods 1 are welded upward with vertical connecting rods 2, and the upper ends of the vertical connecting rods 2 are welded together with a rectangular support frame 3. The width of the rectangular support frame 3 is slightly wider than the outer width of the U-shaped concrete drainage trough, about 5-10 cm wide, and the length of the rectangular support frame 3 is slightly shorter than the length of the U-shaped concrete drainage trough, about 2-5 cm shorter.

[0021] Two horizontal inner support rods 4 are welded on both sides of the transverse connecting rod 1. The inner support rods 4 are perpendicular to the transverse connecting rods 1. The inner support rods 4 connect the transverse connecting rods 1 on both sides together. The length of the inner support rods 4 is equal to the inner width of the U-shaped concrete drainage trough. In order to prevent the inner support rods 4 from scratching the concrete surface of the U-shaped concrete drainage trough, rubber pads are preferably provided at both ends of the inner support rods 4.

[0022] An extrusion piece 5 is rotatably connected to the transverse connecting rod 1 between the two inner support rods 4 on each side. There are four extrusion pieces 5 in total, and the four extrusion pieces 5 are respectively distributed at the four corners inside the U-shaped concrete drainage trough. The extrusion piece 5 is perpendicular to the transverse connecting rod 1, and the extrusion piece 5 can rotate around the transverse connecting rod 1. In this embodiment, a circular hole 53 is provided in the middle of the extrusion piece 5, and the transverse connecting rod 1 passes through the circular hole 53 to realize the rotational connection between the extrusion piece 5 and the transverse connecting rod 1. In this embodiment, the extrusion piece 5 is cylindrical as a whole, and a hoisting hole 51 is provided on the side of the extrusion piece 5 facing the inside of the U-shaped concrete drainage trough, and a hoisting rope 6 is tied to the hoisting hole 51, and the hoisting rope 6 is connected to the hoisting machine. The side of the extrusion piece 5 away from the inside of the U-shaped concrete drain trough is an upturned elbow 52, ​​and the horizontal distance between the outermost end of the elbow 52 and the transverse connecting rod 1 is greater than the horizontal distance between the inner wall of the U-shaped concrete drain trough and the transverse connecting rod 1, that is, when the end of the extrusion piece 5 close to the lifting rope 6 rotates upward, the end of the elbow 52 rotates downward to tightly squeeze the inner wall of the U-shaped concrete drain trough, so that when hoisting upward, when the end of the extrusion piece 5 close to the lifting rope 6 rotates upward around the transverse connecting rod 1, the elbow 52 rotates downward to tightly press against the inner wall of the U-shaped concrete drain trough, and the more upward force is applied, the greater the force of the elbow 52 squeezing the inner wall of the U-shaped concrete drain trough, so that the firmness during hoisting can be ensured. In this embodiment, the extrusion piece 5 is preferably a cast steel part. In order to prevent the elbow 52 from scratching the inner wall of the U-shaped concrete drain trough, the outer surface of the elbow 52 is preferably wrapped with a rubber layer, and the wrapped rubber layer can also increase the friction between the elbow 52 and the inner wall of the U-shaped concrete drain trough.

[0023] When in use, the lifting ropes 6 passing through the four corners of the lifting holes 51 of the extrusion piece 5 are connected to the lifting machine, and then the worker lifts the rectangular support frame 3 to put the tool down into the U-shaped concrete drainage trough, presses the tool downward, and the rectangular support frame 3 is placed on the upper surface of the U-shaped concrete drainage trough. The four extrusion pieces 5 are located in the lower middle position of the U-shaped concrete drainage trough, and then the lifting machine starts to lift upward. As the lifting rope 6 is tightened upward, the extrusion piece 5 begins to rotate around the horizontal connecting rod 1, and the end facing the inside of the U-shaped concrete drainage trough rotates upward under the tension of the lifting rope 6 At this time, the elbow 52 starts to rotate downward, and the elbow 52 tightly squeezes the inner wall of the U-shaped concrete drainage trough. As the lifting rope 6 is tightened, the squeezing force becomes larger and larger, and then the U-shaped concrete drainage trough can be lifted. When the U-shaped concrete drainage trough is lifted to the required position and lowered, the extrusion piece 5 can be rotated in the opposite direction to allow the elbow 52 to rotate upward and separate from the inner wall of the U-shaped concrete drainage trough. If the squeezing force is too large, a hammer can be used to gently tap one side of the lifting hole 51 to rotate the extrusion piece 5, so that the elbow 52 can leave the inner wall of the U-shaped concrete drainage trough. Figure 4 As shown, the entire tool is then lifted out of the U-shaped concrete drain trough and the next U-shaped concrete drain trough can be hoisted.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
