Description

TECHNICAL FIELD

[0001] The utility model relates to continuous casting machine technical field, namely a slab continuous casting machine fan -shaped section roll gap measuring tool. BACKGROUND

[0002] In the prior art, after the repair of the fan-shaped section of the continuous casting machine is completed, the roll gap distance between the three-section rollers of the fixed side and the three-section rollers of the movable side of the fan-shaped section needs to be accurately measured to ensure that the thickness tolerance of the cast slab meets the standard. Since the three-section rollers of the movable side (outer arc) and the fixed side (inner arc) of the fan-shaped section are arranged in arc-shaped cooperation, it is impossible to use a general measuring tool for measurement, and therefore a special measuring tool that can accurately and conveniently measure the roll gap of the fan-shaped section needs to be developed to ensure the measurement accuracy of the roll gap of the fan-shaped section. SUMMARY

[0003] The utility model discloses a kind of slab continuous casting machine fan-shaped section roll gap measuring tools, which are measured reliably and conveniently.

[0004] The technical solution of the utility model is as follows: a slab continuous casting machine fan-shaped section roll gap measuring tool includes a hammer handle, a cylindrical hammer head is connected to the front end of the hammer handle, the one end surface of the cylindrical hammer head has an internal thread through hole, and a fine adjustment knob is screwed to the internal thread through hole; the other end surface of the cylindrical hammer head also has an internal thread through hole, and a quick adjustment knob is screwed to the internal thread through hole; the thread pitches of the external threads of the fine adjustment knob and the quick adjustment knob are different.

[0005] In the above-mentioned scheme, it further includes:

[0006] The fine adjustment knob and the quick adjustment knob are both composed of a threaded rod and a cap.

[0007] The thread pitch of the threaded rod of the fine adjustment knob is 1 mm, and the thread pitch of the threaded rod of the quick adjustment knob is 2 mm.

[0008] The surface cross section of the fine adjustment knob and the quick adjustment knob is trapezoidal.

[0009] The utility model discloses a advantage is: 1, adopt the handle of hammer, cylindrical hammer head structure, can extend into the measuring part, namely convenient with the quantity of hammer and send into the arc roll gap between sector segment, to the roll gap of sector segment three section rollers accurate multi -point position measurement is carried out. 2, adopt the knob of fine adjustment, fast -adjusting knob two kinds of knob design, through the height knob of fine adjustment of quantity of hammer head, adjust the length of measurement, simple and convenient operation, the measurement precision is high, solve the problem of sector segment three section rollers roll gap multi -point position measurement difficult, the big problem of measurement value deviation. The knob of fine adjustment, fast -adjusting knob can be fast with the length of quantity of hammer and adjust to the estimated length, then use the knob of fine adjustment to carry out accurate adjustment, shorten the adjustment time of quantity of hammer, convenient personnel measurement, improve the measurement precision. 3, as the knob of fine adjustment of quantity, the outer end surface of fast -adjusting knob adopts trapezoidal design, can be more convenient cylindrical hammer head and put into the middle of roll gap, avoid cylindrical hammer head and roll surface jam and convenient measurement. 4, the knurled surface of the knob of fine adjustment, fast -adjusting knob side is processed, prevents the slip, convenient personnel operation.

[0010] The embodiments of the utility model will be described further in detail below with reference to the drawings. DRAWINGS

[0011] Figure 1 It is the structural diagram of the utility model.

[0012] Figure 2 It is the arrangement structure diagram of the quantity of hammer head and arc roll gap. PREFERRED EMBODIMENT
