[0002] The H-shaped steel of the forklift mast is mainly composed of a web and flanges. There are four flanges, which are set on both sides of the outer end of the web. The cross section of the steel is H-shaped. There is a certain proportional relationship between the flange width and the web height. According to the different flange widths, H-shaped steel can be divided into wide flange (HW series), medium flange (HM series) and narrow flange (HN series) types.

[0049] The steel wing coordination mechanism 200 includes a stabilizing outer plate 210 provided on the U-shaped groove end and four pads 230 provided on the four ends of the stabilizing outer plate 210. The stabilizing outer plate 210 is an H-shaped structure as a whole. Four slide grooves 2106 are provided inside the stabilizing outer plate 210, two positioning plates 220 are provided on the stabilizing outer plate 210, two shaft sleeves 2101 are installed on the stabilizing outer plate 210, and a first bolt 2102 is provided in the shaft sleeve 2101.

A second bolt 2103 passes through the screw hole at the top of the main baffle 240, which is used to limit and fix the main baffle 240 after transverse movement.
[0050] A main baffle 240 and a second bolt 2103 disposed in a screw hole at the top of the main baffle 240 are movably mounted in two adjacent slide grooves 2106. Furthermore, two vertical grooves 2401 are formed on the inner side of the main baffle 240, two sliders 250 movably mounted in the two vertical grooves 2401, a secondary baffle 2501 mounted on the outside of the two sliders 250, and a third bolt 2502 disposed in a screw hole inside the secondary baffle 2501.
[0051] A support plate 2503 is provided at the bottom of the auxiliary baffle 2501, and the support plate 2503 is used to provide stability protection for the main baffle 240;
[0052] A first limiting hole 2104 and two second limiting holes 2105 are formed inside the stabilizing outer plate 210;
[0053] The stabilizing outer plate 210 cooperates with four sets of wing width adjustment mechanisms 500 to provide a support platform for centering and calibrating the U-shaped groove;
[0054] The wing width adjustment mechanism 500 includes a track plate 530 movably mounted in the slide slot 2106, a cross bar 510 movably mounted in the pad 230, a fourth spring 520 disposed on the outside of the cross bar 510, the inner end of the cross bar 510 being mounted in the track plate 530, a sheath 540 disposed inside the track plate 530, and a stud disposed on the outside of the sheath 540 extending through the track plate 530 to the outside of the track plate 530, with a nut 550 disposed on the stud.
[0055] The outer wall of the track plate 530 is provided with a scale for measuring the width of the inner flange of the H-shaped steel 100, and the inner wall of the track plate 530 is provided with a limiting groove for constraining the stud in the sheath 540;
[0056] The inner wall of the sheath 540 is provided with a non-slip rubber sleeve;
[0057] The laser detection head 600 is inserted into the interior of the sheath 540 , and the inner end of the laser detection head 600 faces the wing plate forming the U-shaped groove, for detecting the thickness of the wing plate.
[0058] When the H-shaped steel 100 is turned sideways until the U-shaped groove on one side is vertically upward, the stabilizing outer plate 210 is placed on the top of the U-shaped groove. At this time, the two sets of web auxiliary mechanisms 300 provided in the stabilizing outer plate 210 are adapted to be engaged with the inner side of the U-shaped groove. Then, the two first bolts 2102 are tightened, and the two sets of web auxiliary mechanisms 300 engaged with the inner side of the U-shaped groove are locked.
[0059] The fourth spring 520 that bears pressure on the inner side of the pad 230 will push the track plate 530 in the opposite direction to press it toward the wing plate forming the U-shaped groove, then loosen the nut 550, and adjust the combined laser detection head 600 and the sheath 540 vertically along the inside of the track plate 530 until the four evenly distributed laser detection heads 600 are along the two wing plates and gradually adjust the height difference in the vertical direction, then tighten the four nuts 550, at this time, the four laser detection heads 600 that form the height difference can perform horizontal detection along the two horizontally placed wing plates, and at the same time, through By loosening the third bolt 2502, the auxiliary baffle 2501 and the main baffle 240 are relatively expanded until the two sets of expanded auxiliary baffles 2501 and the main baffle 240 provide anti-interference protection for the four laser detection heads 600 that form a height difference. As the device moves laterally at a uniform speed along the U-shaped groove, the four laser detection heads 600 that form a height difference can continuously perform thickness detection on the two wing plates that constitute the U-shaped groove.

[0060] Example 2:
[0061] Combine Figures 4 to 6As shown, based on Example 1, the web assist mechanism 300 includes an outer support rod 310 movably mounted in a shaft sleeve 2101, a base 320 mounted at the bottom end of the outer support rod 310, two force arms 330 movably mounted at both ends of the base 320, two outer plates 340 movably mounted at the bottom ends of the force arms 330, a first shaft rod 350 disposed and transversely within the two outer plates 340, a first wheel sleeve 3501 movably mounted on the outside of the first shaft rod 350, and two first shaft rods 350, brackets 360 are disposed outside the two first shaft rods 350, and second springs 380 are disposed inside the brackets 360, a base 3601 disposed on the brackets 360, and a first spring 370 connected to the top of the base 3601;
[0062] The other end of the first spring 370 is connected to the bottom end of the base 320;
[0063] The bracket 360 is in a T-shaped structure as a whole, and the vertically upward end of the bracket 360 is adapted to penetrate the interior of the outer support rod 310;
[0064] Both ends of the second spring 380 are adapted to bear pressure between the two first shafts 350 .
[0065] Preferably, the outer support rod 310 is composed of two sector-shaped segments and a cylindrical end, and the gap formed in the two sector-shaped segments is used to provide a limit constraint for the top end of the bracket 360;
[0066] The second spring 380 is fixedly mounted in the middle of the inner cavity of the bracket 360, and the two first shafts 350 pass through the inner cavity of the bracket 360 and bear pressure on both ends of the second spring 380 respectively.
[0067] When the outer support rod 310 is lifted upward until the top of the bracket 360 is pressed by the bottom of the stabilizing outer plate 210, the base 320 drives the two lever arms 330 to lift upward, and the two lever arms 330 cooperate with the two sets of outer plates 340 to pull the two first shaft rods 350 toward the bracket 360 to retract. At this time, the four first shaft rods 350 and the four first wheel sleeves 3501 can quickly adapt to the upward U-shaped groove of the H-shaped steel 100;
[0068] After the two sets of web auxiliary mechanisms 300 move laterally along the U-shaped groove at a uniform speed, the two sets of web auxiliary mechanisms 300 that move stably can detect the size of the U-shaped groove in the entire H-shaped steel 100.
[0069] Example 3:
[0070] Combine Figures 1 to 3As shown, on the basis of Example 1, the auxiliary energy supply mechanism 400 includes a chassis 410 movably installed in the first limiting hole 2104, a linkage chassis 450 movably installed in the two second limiting holes 2105, and the linkage chassis 450 passes through the two second limiting holes 2105 and is fixedly installed on the chassis 410 at both ends thereof, a support rod 420 passing through the chassis 410 and fixed to the middle of the top surface of the stabilizing outer plate 210, a gasket 430 installed at the top end of the support rod 420, a third spring 440 arranged on the outside of the support rod 420, a motor 460 installed in the chassis 410, a drive pulley 4601 installed on the transmission shaft in the motor 460, a second shaft 470 movably installed in the linkage chassis 450, a drive pulley 4701 installed at the inner end of the second shaft 470, and a second wheel sleeve 4702 installed at the other end of the second shaft 470;
[0071] The driving pulley 4601 and the transmission pulley 4701 are connected with a transmission belt 480;
[0072] The outer walls of the first and second wheel sleeves 3501 and 4702 are both provided with corrugated grooves to increase the friction resistance with the inner web of the H-shaped steel 100;
[0073] The linkage chassis 450 is composed of two L-shaped support plates and an oval shell. The drive shaft in the motor 460 is adapted to pass through the top end of the oval shell, and the drive pulley 4701 is adapted to pass through the bottom end of the oval shell. The two L-shaped support plates pass through the two second limiting holes 2105 and are fixedly mounted on the chassis 410 at both ends.
[0074] The driving pulley 4601 is arranged in the upper cavity of the linkage chassis 450, the transmission pulley 4701 is arranged in the lower cavity of the linkage chassis 450, the transmission belt 480 is arranged in the inner cavity of the linkage chassis 450 and is transmission-connected to the driving pulley 4601 and the transmission pulley 4701, and the driving pulley 4601, the transmission pulley 4701 and the transmission belt 480 are located in the inner cavity of the elliptical shell.
[0075] Preferably, the top end of the third spring 440 bears pressure on the bottom of the gasket 430, and the bottom end of the third spring 440 bears pressure on the chassis 410. When the chassis 410 loses external pressure and receives downward pressure from the third spring 440, the second shaft 470 and the second wheel sleeve 4702 supported by the elliptical housing can be pressed tightly against the web inside the H-shaped steel 100.
[0076] The driving pulley 4601 and the transmission pulley 4701 can be replaced by gears, and the transmission belt 480 can be replaced by a chain. When the driving pulley 4601 and the transmission pulley 4701 are replaced by gears, the interior of the oval housing needs to be filled with lubricating oil.
[0077] When the motor 460 is powered on and started, the transmission shaft inside it cooperates with the drive pulley 4601 to drive the transmission belt 480, and the transmission pulley 4701 driven by the transmission belt 480 and the second shaft 470 will rotate at a constant speed, and finally the second wheel sleeve 4702 set at the other end of the second shaft 470 will move stably along the inner web of the H-shaped steel 100.
[0078] The working principle and usage process of the present invention are as follows: the two first bolts 2102 are loosened in advance, and then the two outer support rods 310 are lifted upward along the inner cavities of the two shaft sleeves 2101 until the two sets of web auxiliary mechanisms 300 are in a retracted state. Then, the stabilizing outer plate 210 is placed toward the end of the U-shaped groove on one side of the H-shaped steel 100. Then, the two outer support rods 310 are released. At this time, the two first springs 370 in a compressed state will quickly push the bracket 360 downward, and the combined auxiliary baffle 2501 and the slider 250 will be pushed outward quickly until the two first wheel sleeves 3501 fit in place with the inner wall of the U-shaped groove.
[0079] Then, the device is moved to one end of the U-shaped groove. At this time, the support rod 420 fixed on the top of the stabilizing outer plate 210 will provide downward elastic support force to the third spring 440 under the pressure of the gasket 430. As a result, the chassis 410 and the linkage chassis 450 will be pressed downward. At this time, the second wheel sleeve 4702 is pressed tightly against the web inside the H-shaped steel 100.
[0080] Then, according to the inspection requirements of the double wing panels on one side of the H-shaped steel 100, the four nuts 550 are adjusted. By loosening the nuts 550 and controlling the sleeve 540 to slide vertically along the slideway inside the track plate 530, the sleeve 540 moves to the selected position of the wing panel of the H-shaped steel 100. The stabilizing outer plate 210 is used as the initial distance for inspection, and the direction of inspection adjustment is directly below the stabilizing outer plate 210. After the four sleeves 540 are fixed at the selected positions on both side walls of the double wing panels, the four laser inspection heads 600 installed inside the four sleeves 540 can then perform wall thickness inspection on the selected positions of the outer walls of the double wing panels.
[0081] The motor 460 is started, and its internal transmission shaft cooperates with the driving pulley 4601 to transmit the transmission belt 480. The other end of the transmission belt 480 transmits the transmission pulley 4701 and the second shaft 470. At this time, the second wheel sleeve 4702 arranged on the outside of the second shaft 470 will effectively assist the rotation and transverse movement along the web inside the H-shaped steel 100, and the four first wheel sleeves 3501 will cooperate to transversely move along the inner wall of the U-shaped groove, thereby providing effective stabilization support for the transverse movement detection of the four sets of wing width adjustment mechanisms 500 along the wing plate. According to the positions of the four laser detection heads 600 on the outer side of the wing plate, the inner side of the U-shaped groove can adjust the auxiliary baffle 2501 and the main baffle 240 accordingly to extend, until after extension, the main baffle 240 and the auxiliary baffle 2501 provide anti-interference protection for the detection of two of the laser detection heads 600, and the device can effectively and stably transversely move along the U-shaped groove on one side of the H-shaped steel 100, thereby continuously detecting the overall wall thickness of the inner wing plate of the manufactured H-shaped steel 100;
[0082] In addition, the two sets of web auxiliary mechanisms 300 in the device will also detect the regularity of the internal gap during the transverse movement along the inside of the U-shaped groove. Once the device stops at a certain part of the U-shaped groove, the stop position of the device can be intuitively displayed to the staff.
[0083] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
