[0013] In the figure: 1-left bracket, 11-left bracket body, 12-left auxiliary bracket, 13-test rod support rod, 14-left fixing bolt, 2-right bracket, 21-right bracket body, 22-test rod slot, 23-right fixing bolt, 3-speed protection test rod. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, the utility model is a special frame for speed protection test of a strong tape machine, comprising a left bracket 1 and a right bracket 2, and a speed protection test rod 3 is arranged on the left bracket 1 and the right bracket 2.

[0016] like Figure 2 and Figure 3 As shown, the left side bracket 1 includes a left side bracket body 11, a left side auxiliary bracket 12 and a test rod support rod 13; the left side bracket body 11 is in the shape of an "H", and two parallel left side auxiliary brackets 12 are arranged on the top of the left side bracket body 11. The two left side auxiliary brackets 12 are perpendicular to the three surfaces of the left side bracket body 11; a test rod support rod 13 is arranged between the two left side auxiliary brackets 12. The right side bracket 2 includes a right side bracket body 21, which is in the shape of an "H", and a test rod slot 22 is opened on the top of the right side bracket body 21; the top height of the test rod support rod 13 is the same as the bottom height of the test rod slot 22, so that the speed protection test rod 3 remains level when placed on the left side bracket 1 and the right side bracket 2.

[0017] The left side bracket body 11 of the present invention is provided with a left fixing bolt 14, and the right side bracket body 21 is provided with a right fixing bolt 23. The left side bracket 1 and the right side bracket 2 in the present invention are fixed to the belt longitudinal beams at both ends of the speed protection by the left side fixing bolt 14 and the right side fixing bolt 23. A bolt cap is welded to one end of the speed protection test rod 3 on the left side bracket 1, and a plastic-coated steel wire rope is passed through the bolt cap to connect to the speed protection test rod 3. During the speed protection test, the plastic-coated steel wire rope can be pulled down to pull up the speed protection test rod 3; or the other end of the speed protection test rod 3 can be raised by about 200mm above the belt longitudinal beam, and a special support rod can be used to lift the speed protection test rod 3, thereby achieving the purpose of the speed protection test.

[0018] The utility model discloses reduce the labor intensity of worker, improve test security, and the both ends of speed protection test pole 3 can be tested, and after testing, it does not need to remove, and one can conveniently, safely operate. The utility model discloses simple processing, convenient installation, economic and practical, can batch production.
