Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1-2, the present invention discloses a drawing test device for performing a drawing test on a steel pipe structure, wherein in this embodiment, the steel pipe structure comprises two steel pipes and a connecting pipe connecting the two steel pipes into a whole.

The drawing test device comprises a fixed frame 100, a driving piece 200, a screw rod mechanism 300 and two clamping pieces 400, wherein the fixed frame 100 comprises a base 110, a first upright column 120, a second upright column 130 and a supporting table 140, two ends of the supporting table 140 are respectively connected with the upper ends of the first upright column 120 and the second upright column 130, the driving piece 200 is fixed on the supporting table 140 and drives the screw rod mechanism 300, the screw rod mechanism 300 penetrates through the supporting table 140 and is in threaded connection with the supporting table 140, the screw rod mechanism 300 is connected with one clamping piece 400, the base 110 is connected with the other clamping piece 400, the two clamping pieces 400 are arranged at intervals, and one clamping piece is positioned right above the other clamping piece.

In this embodiment, two clamping members 400 respectively clamp two ends of the steel pipe structure, one clamping member 400 clamps the upper end of the steel pipe structure and is connected to the screw rod mechanism 300, the clamping member 400 can move upward along with the screw rod mechanism 300, the driving member 200 drives the screw rod mechanism 300 to rotate and move upward, the other clamping member 400 clamps the lower end of the steel pipe structure, and the clamping member 400 is fixedly connected to the base 110.

When the driving piece 200 drives the screw rod mechanism 300 to move upwards, the steel pipe mechanism is further subjected to a drawing test.

The driving member 200 includes a motor 210 and a first gear 220 connected to the motor 210;

the screw mechanism 300 includes a second gear 310 and a screw 320 passing through the second gear 310 and threadedly engaged with the second gear 310, the first gear 220 and the second gear 310 being engaged.

In this embodiment, when the motor 210 rotates, the first gear 220 is driven to rotate; the first gear 220 drives the second gear 310, and the second gear 310 is screwed with the screw rod 320, so as to drive the screw rod 320 to integrally move upwards, and finally the two clamping members 400 are mutually matched to draw the steel pipe structure.

Reinforcing ribs 10 are respectively arranged on two sides of the first upright column 120 and the second upright column 130, and the reinforcing ribs 10 are used for improving the supporting strength of the first upright column 120 and the second upright column 130.
