Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe column positioning, and specifically to a vertical positioning device for steel pipe columns. Background Art

[0002] Steel pipe columns are made of single or multiple steel pipes through welding or machining, and the cross-sectional shapes include circular, square, rectangular, etc. Steel pipe columns are not only used in steel structure buildings, but also commonly found in the following scenarios: large-scale projects such as offshore platforms, bridges, and towers, as well as industrial fields such as mechanical equipment.

[0003] In the prior art, through the pre-lifting adjustment of the lifting adjustment component, steel pipe columns of different lengths can be adapted, enabling the plumb bob device to adapt to steel pipe columns of different lengths.

However, in the prior art, on the one hand, the position angle of the bottom positioning plate cannot be adjusted, and at the same time, it is not convenient to freely adjust the deflection angle of the steel pipe column.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present invention.

[0023] Example 1, please refer to Figures 1-4 , a vertical positioning device for steel pipe columns, comprising a bottom fixed plate 1. Positioning and supporting mechanisms 2 are provided at the four corners of the bottom fixed plate 1. Two displacement clamping mechanisms 3 are provided on the bottom fixed plate 1, and the two displacement clamping mechanisms 3 are symmetrically arranged on the bottom fixed plate 1. An extraction and placement clamping plate mechanism 4 is provided on the displacement clamping mechanism 3. A feeding drive mechanism 5 is provided on the side of the bottom fixed plate 1. A rotating ring 6 is provided on the bottom fixed plate 1. A deflection drive mechanism 7 is provided between the rotating ring 6 and the bottom fixed plate 1. Two deflection adjustment mechanisms 8 are provided on the rotating ring 6. The deflection adjustment mechanism 8 is connected to the upper clamping plate mechanism 9. A level is provided on the bottom fixed plate 1. The positioning and supporting mechanism 2 is used to adjust and position the position of the bottom fixed plate 1. The feeding drive mechanism 5 is used to drive the displacement clamping mechanism 3. The deflection drive mechanism 7 is used to drive the rotating ring 6 to rotate. The deflection adjustment mechanism 8 is used to adjust the angle of the upper clamping plate mechanism 9, so as to adjust the vertical state of the steel pipe column.

[0024] The positioning and supporting mechanism 2 includes an external-thread supporting sleeve 201 threadedly connected to the bottom fixing plate 1. The upper part of the side of the external-thread supporting sleeve 201 is fixedly connected to a first rotating handle 202. The bottom of the side of the external-thread supporting sleeve 201 is rotatably connected to two first deflecting shafts 203. One end of the first deflecting shaft 203 away from the external-thread supporting sleeve 201 is rotatably connected to an inner deflecting ring 204. The outer side of the inner deflecting ring 204 is rotatably connected to two second deflecting shafts 205. The two second deflecting shafts 205 are symmetrically arranged on the inner deflecting ring 204. The first deflecting shaft 203 and the second deflecting shaft 205 are perpendicular to each other. One end of the second deflecting shaft 205 away from the inner deflecting ring 204 is rotatably connected to an outer supporting ring 206. The internal thread of the external-thread supporting sleeve 201 is threadedly connected to a feed inserting rod 207. The top of the feed inserting rod 207 is fixedly connected to a second rotating handle 208.

[0025] Specifically, rotating the first rotating handle 202 can drive the external-thread supporting sleeve 201 to rotate, thereby controlling the positions of the inner deflecting ring 204 and the outer supporting ring 206. Since both the inner deflecting ring 204 and the outer supporting ring 206 can deflect, it can be ensured that the outer supporting ring 206 always makes positive contact with the ground for support, so as to adjust the height and angle of the bottom fixing plate 1. At this time, rotating the second rotating handle 208 can drive the feed inserting rod 207 to feed, so as to insert into the ground, so as to ensure that the position of the bottom fixing plate 1 does not change relative to the ground.

[0026] The displacement clamping mechanism 3 includes an internal thread sleeve 301 rotatably connected to the bottom fixing plate 1. A first bevel gear 302 is fixedly connected to the outer side of the internal thread sleeve 301. A feed screw rod 303 is threadedly connected inside the internal thread sleeve 301. One end of the feed screw rod 303 located inside the bottom fixing plate 1 is rotatably connected to a feed clamping plate 304. The feed clamping plate 304 is fixedly connected to a feed slide rod 305. The feed slide rod 305 passes through the bottom fixing plate 1 and is slidably connected to the bottom fixing plate 1. A feed clamping plate groove 306 is provided at a position corresponding to the feed clamping plate 304 on the bottom fixing plate 1. A vertical placement groove 307 is provided vertically on the feed clamping plate 304. A number of size scales are provided on the feed slide rod 305. The extraction and discharge clamping plate mechanism 4 includes a placement clamping plate 401. The placement clamping plate 401 is fixedly connected to an end baffle 402. The cross-section of the placement clamping plate 401 is the same as that of the vertical placement groove 307. The feed driving mechanism 5 includes a motor base 501 fixed to the side of the bottom fixing plate 1. A double-headed motor 502 is provided on the motor base 501. The output shafts of the double-headed motor 502 are fixedly connected to two first driving shafts 503. One end of the first driving shaft 503 away from the double-headed motor 502 is fixedly connected to a second bevel gear 504. The second bevel gear 504 meshes with a third bevel gear 505. The third bevel gear 505 is coaxially fixedly connected to a second driving shaft 506. The second driving shaft 506 is rotatably connected to a driving shaft seat 507. The driving shaft seat 507 is fixedly connected to the bottom fixing plate 1. One end of the second driving shaft 506 away from the third bevel gear 505 is fixedly connected to a fourth bevel gear 508. The fourth bevel gear 508 meshes with the first bevel gear 302.

[0027] Specifically, turning on the double-headed motor 502 can drive the first driving shaft 503 to rotate. The rotation of the first driving shaft 503 will drive the second bevel gear 504 to rotate, and then drive the third bevel gear 505 to rotate. The rotation of the third bevel gear 505 will drive the second driving shaft 506 to rotate. The rotation of the second driving shaft 506 will drive the fourth bevel gear 508 to rotate. The rotation of the fourth bevel gear 508 will drive the first bevel gear 302 to rotate, thereby driving the internal thread sleeve 301 to rotate, so as to drive the feed screw rod 303 to feed and expand and contract, and then drive the feed clamping plates 304 on both sides to feed and displace synchronously. When the position of the bottom fixing plate 1 is limited, the steel pipe column can be clamped and positioned by the feed clamping plate 304. When the position of the bottom fixing plate 1 is not fixed yet, the placement clamping plate 401 is placed into the vertical placement groove 307. At this time, the placement clamping plate 401 is clamped on the inner wall or the outer wall of the deep well according to the actual situation, so as to realize the auxiliary positioning of the bottom fixing plate 1. By selecting end baffles 402 of different sizes, the inner side edge of the end baffle 402 can also be used to contact and position the steel pipe column.

[0028] Example 2, continue to refer to Figures 1-4, in the embodiment of the present invention, the deflection driving mechanism 7 includes two mounting side plates 701 fixed to the bottom fixing plate 1. A deflection motor 702 is provided on one of the mounting side plates 701. The output shaft of the deflection motor 702 is fixedly connected to a worm shaft 703. The worm shaft 703 is rotatably connected to the mounting side plate 701. The worm shaft 703 is coaxially fixedly connected to a worm 704. A worm gear 705 is fixedly connected to the outer side of the rotating ring 6. The worm gear 705 meshes with the worm 704. An angle scale is provided on the bottom fixing plate 1, and an angle pointer is provided on the rotating ring 6. The deflection adjustment mechanism 8 includes a first deflection seat 801 fixed to the rotating ring 6. The first deflection seat 801 is rotatably connected to an electric telescopic rod 802. The end of the electric telescopic rod 802 away from the first deflection seat 801 is rotatably connected to a second deflection seat 803. The upper clamping plate mechanism 9 includes a fixing ring 901 fixedly connected to the second deflection seat 803. Two rotating threaded rods 902 are threadedly connected to the fixing ring 901. The two rotating threaded rods 902 are symmetrically arranged on the fixing ring 901. The end of the rotating threaded rod 902 away from the fixing ring 901 is fixedly connected to a third rotating handle 903. The rotating threaded rod 902 is threadedly connected to a feeding plate 904. The feeding plate 904 is fixedly connected to a fixing slide rod 905. The fixing slide rod 905 passes through the fixing ring 901. The fixing slide rod 905 is slidably connected to the fixing ring 901. The end of the fixing slide rod 905 away from the feeding plate 904 is fixedly connected to an upper clamping plate 906. Two positioning contact balls 907 are provided in the vertical direction of the upper clamping plate 906.

[0029] Specifically, turning on the electric telescopic rod 802 can adjust the height and deflection angle of the fixing ring 901. Turning the third rotating handle 903 can drive the rotating threaded rod 902 to rotate, thereby driving the feeding plate 904 to feed, and further driving the fixing slide rod 905 and the upper clamping plate 906 to feed. Cooperating with turning on the deflection motor 702, the rotation of the output shaft of the deflection motor 702 will drive the worm shaft 703 to rotate. The rotation of the worm shaft 703 will drive the worm 704 to rotate. The rotation of the worm 704 will drive the worm gear 705 to rotate, thereby driving the rotating ring 6 to rotate. In this way, the offset angle of the upper clamping plate 906 is adjusted to ensure that the positioning contact balls 907 on both sides of the upper clamping plate 906 are in contact with the surface of the steel pipe column, so as to ensure the positioning and installation of the steel pipe column at a specified vertical angle.

[0030] In the implementation process of the present invention, first, the positioning and supporting mechanism 2 is adjusted according to different actual situations, and then the position of the bottom fixing plate 1 is adjusted and fixed. At the same time, when the feeding drive mechanism 5 is turned on, it can drive the displacement clamping mechanism 3 to feed and displace, so as to limit the contact of the steel pipe column. Similarly, when there is a deep well where excavation construction has been carried out, the position of the gas drainage clamping plate mechanism 4 can be adjusted driven by the displacement clamping mechanism 3, and then it can be on the inner wall or outer wall of the deep well, so as to position the position of the bottom fixing plate 1. At this time, when the deflection drive mechanism 7 is turned on, it can drive the rotating ring 6 to rotate, and cooperate with the deflection adjustment mechanism 8 to adjust the deflection angle of the upper clamping plate mechanism 9, so that the steel pipe column passes through the upper clamping plate mechanism 9 and the displacement clamping mechanism 3, and then the vertical positioning of the steel pipe column can be carried out.

[0031] By setting the positioning and supporting mechanism 2, the position of the bottom fixing plate 1 can be adjusted and fixed. By the feeding drive mechanism 5, the displacement clamping mechanism 3 can be driven, and cooperating with the gas drainage clamping plate mechanism 4, it can be clamped inside or outside the placement position, so as to facilitate the positioning of the bottom fixing plate 1. By the deflection drive mechanism 7, the rotating ring 6 can be driven to rotate and displace. By the deflection adjustment mechanism 8, the deflection angle of the upper clamping plate mechanism 9 can be adjusted, so as to adaptively adjust the angle of the steel pipe column. By the upper clamping plate mechanism 9, it can contact and clamp the steel pipe column, improving the safety and convenience of geological sample detection.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. 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.
