Technical Field

[0001] The utility model relates to the field of track bolt installation technology, in particular to a high-efficiency installation device for U-shaped track bolts. Background Art

[0002] In the field of industrial construction, transport tracks and equipment tracks are extremely common, but the speed and accuracy of bolt installation during construction affect the progress of civil engineering construction.

[0003] A common construction method is to tie the foundation steel bars first. After the tying is completed, a fixed wire rack is made at both ends of the foundation and the center line of the bolt is hung with steel wire to assist in installation. The bolts are installed and welded one by one according to the hung steel wire.

[0004] This traditional installation method is firstly slow in speed, and secondly in terms of precision, some bolts cannot meet the installation requirements of the equipment manufacturer. During acceptance, there are often large deviations that require rework, which is a great waste of manpower and construction time. Utility Model Content

[0007] An efficient installation device for U-shaped track bolts includes two upper angle steels arranged in parallel. A plurality of brackets are vertically fixed to the bottom surface of the upper angle steels along the length direction. A plurality of mounting holes are also opened on the upper surface of the upper angle steels along the length direction. Bolts are inserted into the mounting holes from bottom to top and fixed by nuts. A lower angle steel for vertically supporting the bolts is arranged in parallel below the upper angle steels. The lower angle steel is fixed between the bottom of the bolt and the side of the bracket.

[0008] By adopting the above technical solution, the installation time of U-bolts is saved, thereby reducing the impact on the overall civil engineering progress; because the U-bolts are installed in advance, the installation accuracy of the U-bolts is ensured, and rework caused by unqualified acceptance is avoided, saving labor costs and the time cost of rework.

[0009] Optionally, the bracket includes a support column fixed to the bottom of the upper angle steel and a base plate fixed to the bottom end of the support column.

[0010] By adopting the above technical solution, the bracket is easy to obtain materials, and is easy to assemble and install.

[0011] Optionally, the mounting hole is an elliptical hole, and the direction of the larger diameter of the mounting hole is the same as the length direction of the upper angle steel.

[0012] By adopting the above technical solution, it is convenient to fine-tune the position of the U-bolt.

[0013] In summary, the present invention has at least one of the following beneficial technical effects:

[0014] 1. Saves the installation time of U-bolts, thereby reducing the impact on the overall civil engineering progress;

[0015] 2. Because the U-bolts are installed in advance, the installation accuracy of the U-bolts is ensured, avoiding rework due to unqualified acceptance, saving labor costs and rework time costs;

[0021] The following is combined with Figure 1 -Attached Figure 3 The utility model is described in further detail.

[0022] The present invention discloses an efficient installation device for U-shaped track bolts. Figure 1-Figure 3 , an efficient installation device for U-shaped track bolts is used to assist in positioning the bolts 1, and the device includes a bracket 2, an upper angle steel 3 and a lower angle steel 4.

[0023] Reference Figure 1-Figure 3 The bracket 2 includes a support column 20 and a base plate 21. The support column 20 is a round steel with a diameter of 25 mm. The base plate 21 is a steel plate with a size of 100 mm*100 mm and a thickness of 20 mm. The support column 20 is vertically welded to the top surface of the base plate 21.

[0024] Reference Figure 1-Figure 3Two upper angle steels 3 are arranged horizontally and parallel to each other. The top of the support column 20 is welded and fixed to the bottom surface of the upper angle steel 3. A bracket 2 is set every 2m along the length direction of the upper angle steel 3; a plurality of elliptical mounting holes are evenly opened on the upper angle steel 3 along its own length direction. The position and number of the mounting holes are determined according to the drawings. The direction of the larger diameter of the mounting hole is in the same direction as the length of the upper angle steel 3, so as to facilitate fine-tuning the position of the bolt 1. The bolt 1 is passed through the mounting holes of the two upper angle steels 3 from bottom to top, and the top of the bolt 1 is fixed by a nut.

[0025] Reference Figure 1-Figure 3 The lower angle steel 4 is used to support the bolt 1 in the vertical direction. Two lower angle steels 4 are arranged horizontally and parallel. The lower angle steel 4 is arranged parallel to the bottom of the upper angle steel 3. One side of the lower angle steel 4 is welded to the bottom of the bolt 1, and the other side of the lower angle steel 4 is welded to the support column 20.
