Description

Technical Field:

[0001] The utility model relates to a straightening device, in particular to a steel drill rod straightening device. Background Art:

[0002] During the operation of the calcium carbide furnace, due to the small particle size of the materials, poor fluidity and air permeability, the materials will agglomerate due to high temperature after long-term operation, forming a shell in the furnace chamber, which makes the materials unable to descend. The shell will cause abnormal furnace conditions such as large-scale material collapse and calcium carbide turnover in the furnace chamber. Therefore, when the materials in the furnace agglomerate into a shell, it is necessary to clamp the steel drill rod with a robotic arm, extend the steel drill rod into the furnace chamber through the furnace mouth, and under the drive of the robotic arm, the front end of the steel drill rod hammers the shell to break and lower the shell to achieve the purpose of material surface treatment. However, in a high-temperature environment, the steel drill rod is extremely easy to deform and bend. In order to make the steel drill rod reusable, it is necessary to straighten the deformed steel drill rod. At present, due to the lack of suitable tools, it is often the staff who use a sledgehammer to straighten it. However, the labor intensity is too high, and during the straightening process, two other staff members are needed to assist in fixing the steel drill rod, resulting in low work efficiency. Content of the Utility Model:

[0003] In order to solve the above problems, the purpose of the utility model is to provide a steel drill rod straightening device.

[0016] Figure 1 is a schematic structural diagram of the present utility model;

[0017] In the figure: straightening platform 1, fixing mechanism 2, fixed vertical plate 21, clamping plate 22, first clamping groove 23, support plate 24, slot 25, fixing bracket 31, fixing plate 311, rotating shaft 312, rotating roller 313, pressing mechanism 4, hydraulic cylinder 41, pressing head 42, connecting seat 43, connecting flange 44, second clamping groove 45. Specific embodiments:

[0018] As Figure 1 shown, a steel drill rod straightening device includes a straightening platform 1, and a fixing mechanism 2, a supporting mechanism and a pressing mechanism 4 are provided on the straightening platform 1;

[0019] The fixing mechanism 2 includes a fixed vertical plate 21 fixed on the straightening platform 1. Two clamping plates 22 are provided on the fixed vertical plate 21, and the plate surfaces of the two clamping plates 22 are perpendicular to the plate surface of the fixed vertical plate 21. A slot 25 with an opening downward is formed on the plate surface of the clamping plate 22, and the length of the slot 25 matches the thickness of the fixed vertical plate 21. An arc-shaped first clamping groove 23 is formed on a side wall of the clamping plate 22 in a vertical direction, and the two first clamping grooves 23 on the two clamping plates 22 are located on the same side of the fixed vertical plate 21. A plurality of support plates 24 fixed on the straightening platform 1 are provided on the side of the fixed vertical plate 21 away from the hydraulic cylinder 41. One side wall of the support plate 24 is fixedly welded to the fixed vertical plate 21, which can strengthen the firmness of the fixed vertical plate 21.

[0020] The support mechanism includes two fixing frames 31, and the two fixing frames 31 are respectively arranged on the opposite outer sides of the two clamping plates 22. The bottom end of the fixing frame 31 is fixedly welded to the straightening platform 1.

[0021] The pushing mechanism 4 includes a hydraulic cylinder 41 and a pushing head 42. The cylinder body of the hydraulic cylinder 41 is fixed on the straightening platform 1. The telescopic end of the hydraulic cylinder 41 faces the fixed vertical plate 21 and is perpendicular to the plate surface of the fixed vertical plate 21, and the telescopic end of the hydraulic cylinder 41 is located on the opposite inner sides of the two clamping plates 22. A pushing head 42 is provided at the telescopic end of the hydraulic cylinder 41. A connecting seat 43 is fixedly welded on a side wall of the pushing head 42 away from the fixed vertical plate 21. A plurality of connecting holes are formed in the circumferential direction on the connecting seat 43. A connecting flange 44 is fixed at the telescopic end of the hydraulic cylinder 41, and the connecting seat 43 and the connecting flange 44 are connected by bolts, so that the pushing head 42 can be conveniently replaced.

[0022] An arc-shaped second clamping groove 45 is formed on the side wall in the vertical direction of the pushing head 42 close to the fixed vertical plate 21. The height of the first clamping groove 23 is the same as that of the second clamping groove 45. The first clamping groove 23 and the second clamping groove 45 can respectively clamp and limit the steel drill rod from both sides of the steel drill rod, avoiding the rotation of the steel drill rod during the straightening process.

[0023] In this embodiment, the fixing frame 31 includes two fixing plates 311. Both ends of the rotating shaft 312 are rotatably connected to the two fixing plates 311, and the length direction of the rotating shaft 312 is perpendicular to the telescopic direction of the hydraulic cylinder 41 of the pushing mechanism 4. A rotating roller 313 is provided on the rotating shaft 312, which can facilitate the movement of the steel drill rod, and then adjust the front and rear positions of the steel drill rod according to the bent part of the steel wire.

[0024] Working description:

[0025] When using this embodiment to straighten the deformed and bent steel drill rod, first use the hoisting equipment to move the steel drill rod to be straightened onto the straightening platform 1 and place it on the two rotating rollers 313, and then move the hoisting equipment away.

[0026] Under the action of the rotating roller 313, the staff can easily move the steel drill rod to be straightened back and forth, so that the bent part moves to the pressing head 42. At the same time, since the clamping plate 22 is inserted into the fixed vertical plate 21 through the slot 25, the relative position of the clamping plate 22 and the fixed vertical plate 21 can be adjusted; the two clamping plates 22 can be manually moved so that the two clamping plates 22 are respectively located at both ends of the bent part of the steel drill rod to be straightened, and the unbent parts at both ends of the bent part of the steel drill rod to be straightened are clamped in the two first clamping slots 23 on the two clamping plates 22, so that the two first clamping slots 23 play a limiting role on the steel drill rod to be straightened. At the same time, since the distance between the clamping plates 22 can be adjusted, the positions of the two clamping plates 22 can be adjusted according to the length of the bent part of the steel drill rod, so that the pressing force of the pressing head 42 can be well applied to the bent part of the steel drill rod.

[0027] After that, the hydraulic cylinder 41 is started to extend the telescopic rod, driving the pressing head 42 to move towards the fixed vertical plate 21. During the movement, due to the limitation of the second clamping slot 45, the steel drill rod will not rotate during the pressing process of the pressing head 42, ensuring the smooth progress of the straightening work. Since the steel drill rod is relatively thick and it is not required that the steel drill rod must reach an absolutely straight state when hammering the crust material, during the straightening process, the staff can observe the degree of straightening with the naked eye and rely on experience to judge whether the straightening is completed.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
