Description

Technical Field

[0001] The utility model relates to the technical field of steel strand installation, in particular to an ultra-short steel strand clip connection device. Background Art

[0002] Ultra-short steel strand is a type of prestressed steel strand. Common prestressed steel strands are currently widely used in bridge pre-tensioning and post-tensioning methods with anchor clamps. They are also used in some steel box girder drag-type jacking installations. During the tensioning process, the jack's tensioning stroke is often insufficient and requires inverted jacking. The traditional steel strand clip fastening process is to use steel pipes to pass through the bundle and then knock them so that the clips clamp the steel strands on the anchor.

[0003] Traditional connection devices, such as the "A steel strand clamp fastening device" disclosed in application number "202122154704.2", require workers to manually knock so that the clamp clamps the steel strand to the anchor. This design not only increases the labor intensity of the workers, but also affects the progress of bridge construction to a certain extent, which is not conducive to promotion and use.

[0004] Therefore, how to provide an automatic tapping ultra-short steel strand clip connection device has become a technical problem to be solved by technical personnel in this field. Utility Model Content

[0007] The design of the electric push rod can drive the knocking rod to move vertically and horizontally, so that the knocking rod can realize the automatic knocking function when knocking. In actual use, the electric push rod can be replaced by hydraulic rods, cylinders and other structures.

[0008] Preferably, a mounting groove is preset on the base plate, and a limiting sleeve is connected through the mounting groove.

[0009] A fixing hole is preset on the installation slot, thereby ensuring the stability of the connection between the limiting sleeve and the installation slot.

[0010] Preferably, a knocking rod is connected through the interior of the limiting sleeve, a knocking block is installed at the end of the knocking rod, and a protrusion is installed at the head end of the knocking rod.

[0011] The knocking rod knocks under the action of the knocking block, and the knocking block, the protrusion and the knocking rod are an integrated structure. This design ensures the stability of the connection between the knocking block, the protrusion and the knocking rod.

[0012] Preferably, the lower end surface of the protrusion is connected to the output portion of the electric push rod, and two groups of protrusions are arranged in parallel with the electric push rod.

[0013] With this design, the electric push rod can drive the knocking rod to move vertically and horizontally through the protrusions. The two-group design ensures the stability of the knocking rod when moving.

[0014] Preferably, the support assembly includes a support rod and a support block, the support rod is installed at the bottom of the base plate via a connecting piece, and two support rods are arranged in parallel, the support block is installed at the end of the support rod via a connecting piece, and the lower end surface of the support block is flush with the lower end surface of the knocking block.

[0015] The support rod and the base plate form a disassembly and installation structure through the connecting piece. This design makes it easy for the staff to disassemble and assemble the support rod at a later time. The support block and the support rod form a disassembly and installation structure through the connecting piece. This design makes it easy for the staff to disassemble and assemble the support rod at a later time. Bolts are preset on the support block to ensure the stability of the connection between the support block and the tool anchor, thereby avoiding the device from tipping over when knocked.

[0016] Preferably, the tool anchor is preset with an anchor hole, and there is more than one anchor hole preset.

[0017] The tool anchor adopts the existing structure on the market, so it will not be described in detail. The shape of the anchor hole is the same as the shape of the clip, which is a trapezoidal structure.

[0018] The beneficial effects of the utility model are:

[0019] When the utility model is in use, the electric push rod is used to drive the knocking rod to move vertically and horizontally, so that the clamping piece clamps the steel strand on the anchor in an automatic knocking manner. This design not only reduces the labor intensity of the staff, but also improves the progress of bridge construction to a certain extent, which is conducive to popularization and use.
