BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for describing the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model.

[0017] Figure 1 A schematic structural diagram of a pusher stroke comparison tool provided in this application.

[0018] The accompanying drawings are marked with: 100 - main rod, 200 - measuring ruler, 210 - marking scale, 300 - handle, 400 - sheath, 410 - tapered cylinder, 411 - opening cavity, 420 - straight cylinder. DETAILED DESCRIPTION

[0019] This embodiment provides a pusher stroke comparison tool, which is used for the stroke comparison of the pusher of the arc section of the straightening machine. Please refer to Figure 1 The pusher stroke comparison tool comprises a main rod 100, a measuring ruler 200, a handle 300 and a sheath 400. The measuring ruler 200 is fixedly mounted on one end of the main rod 100, and the handle 300 is fixedly mounted on an end of the main rod 100 away from the measuring ruler 200. The sheath 400 is fixedly mounted on the main rod 100, and the sheath 400 has an open cavity 411, and the handle 300 is located in the open cavity 411.

[0020] Among them, Figure 1 As shown, the length direction of the ruler 200 is perpendicular to the length direction of the main rod 100. In particular, the length of the ruler 200 is the minimum value of the stroke limit of the arc section pusher of the tensioning and straightening machine. When in use, the inspector chooses a safe position to stand, holds the handle 300, drives the ruler 200 through the main rod 100 to the pusher stroke position, and compares the ruler 200 with the pusher.

[0021] The measuring ruler 200 is used to reach each pusher stroke position for comparison. When it is not shorter than the measuring ruler 200, it indicates that the pusher stroke is within the normal working range; when it is shorter than the measuring ruler 200, it indicates that the pusher does not meet the requirement of the minimum stroke limit, and the pusher needs to be adjusted accordingly to restore the pusher to the normal working range.

[0022] By comparing and adjusting the strokes of all pushers in the arc section of the straightening machine, accidents can be avoided. Compared with the method of comparing the pusher strokes with a ruler or a tape measure, the tool of the present application has the advantages of simple and convenient operation and high working efficiency.

[0023] The tool also installs a sheath 400 on the main rod 100 and arranges the handle 300 in an opening 411 of the sheath 400. The sheath 400 protects the inspector, improves production and safety hazards, and improves the safety factor of the operation.

[0024] In some embodiments, see Figure 1 The ruler 200 is provided with a plurality of marking scales 210, which are evenly spaced in sequence along the length direction of the ruler 200. By arranging the marking scales 210, when the ruler 200 reaches each pusher stroke position for comparison, the extent of the extension of the pusher can be roughly understood first, which is also more conducive to intuitive judgment during comparison.

[0025] In some implementations, a circle of marking scales 210 is provided every 10 mm along the length direction of the ruler 200 to facilitate intuitive judgment by inspectors.

[0026] The present embodiment provides a specific design scheme for a measuring ruler 200. For the pusher of the arc section of the straightening machine, the pusher stroke shall not be less than 4 cm under normal working conditions, that is, the minimum stroke limit is 40 mm, and the length of the measuring ruler 200 is limited to 40 mm. A marking scale 210 is engraved at 10 mm, 20 mm, and 30 mm along the length of the measuring ruler 200. A black line with a width of 0.2 mm is marked around the measuring ruler 200 as the marking scale 210, and Arabic numerals 1, 2, and 3 are marked respectively. In addition, Arabic numeral 4 is marked at the top of the measuring ruler 200.

[0027] In some embodiments, the measuring ruler 200 is cylindrical, and the diameter of the measuring ruler 200 is 6 mm-10 mm. The cylindrical diameter of the measuring ruler 200 is preferably 8 mm.

[0028] In some embodiments, the length of the main rod 100 is 400 mm-600 mm, and the length of the main rod 100 is preferably 500 mm.

[0029] In some embodiments, the main rod 100 is cylindrical, the handle 300 is spherical, and the diameter of the handle 300 is larger than the diameter of the main rod 100. The diameter of the main rod 100 is preferably 8 mm, and correspondingly, the diameter of the handle 300 is preferably 15 mm.

[0030] In some embodiments, see Figure 1 The sheath 400 includes a conical cylinder portion 410 and a straight cylinder portion 420. The inner cavity of the conical cylinder portion 410 is an open cavity 411. The conical cylinder portion 410 has a small mouth end located at the small mouth of the conical cylinder and a large mouth end at the large mouth of the conical cylinder. One axial end of the straight cylinder portion 420 is connected to the small mouth end of the conical cylinder portion 410. The straight cylinder portion 420 is fixedly sleeved outside the rod body of the main rod 100. The main rod 100 is inserted into the conical cylinder portion 410, and the handle 300 is located at the large mouth end of the conical cylinder portion 410.

[0031] In some embodiments, the sheath 400 is fixed on the main pole 100 to facilitate the inspector to carry it.

[0032] Regarding material selection, the material of the sheath 400 can be thermoplastic polyurethane elastomer rubber, which can smoothly play a protective role; the material of the main rod 100 can be stainless steel; the material of the handle 300 can be plastic; the material of the ruler 200 can be stainless steel, and the ruler 200 is welded to the main rod 100.
