One end of the positioning piece is rotatably connected to the fixing frame, and the driving assembly and the other end of the positioning piece are transmission-connected.

[0052] First, a steel beam assembly device 2 according to an embodiment of the present utility model is described with reference to the accompanying drawings.

[0053] like Figure 1 As shown, the steel beam assembly device 2 includes a reference platform 500 and a steel beam end plate positioning tool 1, the steel beam end plate positioning tool 1 is detachably connected to the reference platform 500, and the steel beam end plate positioning tool 1 is suitable for connecting with the end plate 710 of the steel beam 700.

[0054] Among them, Figure 1 As shown, there are multiple steel beam end plate positioning tools 1, and the multiple steel beam end plate positioning tools 1 include a first positioning tool 600 and a second positioning tool 610.

[0055] The first positioning fixture 600 is connected to the reference platform 500 , the second positioning fixture 610 is connected to the reference platform 500 and is spaced apart from the first positioning fixture 600 , and the first positioning fixture 600 and the second positioning fixture 610 are respectively connected to the end plates 710 at both ends of the steel beam 700 .

[0056] The reference platform 500 may be an H-shaped steel.

[0057] Specifically, when the steel beam 700 is assembled using the steel beam assembly device 2, the first positioning jig 600 can adjust the angle of one end plate 710 and fix the end plate 710, and the second positioning jig 610 can adjust the angle of another end plate 710 and fix the end plate 710, that is, the first positioning jig 600 and the second positioning jig 610 can position the end plates 710 at both ends of the steel beam 700, and then place the main body of the steel beam 700 between the first positioning jig 600 and the second positioning jig 610, and weld the end plate 710 and the main body of the steel beam 700 to achieve the assembly of the steel beam 700.

[0058] In addition, it should be noted that the steel beam assembly device 2 can also be provided with a plurality of pads 510, and the plurality of pads 510 are arranged at intervals along the length direction of the reference platform 500, and the plurality of pads 510 are supported under the steel beam 700, so that the plurality of pads 510 can be used to fix the steel beams 700 of different sizes at a suitable height, so as to facilitate welding connection of the steel beam 700 and the end plate 710.

[0059] The steel beam end plate positioning tool 1 according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0060] like Figure 1-Figure 8 As shown, the steel beam end plate positioning tool 1 according to an embodiment of the utility model includes a fixing frame 100, a positioning member 200 and a driving assembly 300.

[0061] The fixing frame 100 has a first end 110 and a second end 120 in the first direction, the positioning member 200 and the fixing frame 100 are arranged along the second direction, and one end of the positioning member 200 in the first direction is rotatably connected to the first end 110, the positioning member 200 is suitable for connecting with the end plate 710 of the steel beam 700, the driving assembly 300 is arranged on the fixing frame 100 and is adjacent to the second end 120, and the driving assembly 300 is transmission-connected to the other end of the positioning member 200 in the first direction to drive the positioning member 200 to rotate relative to the fixing frame 100.

[0062] As shown in the accompanying drawings, the direction indicated by arrow A is the first direction, and the direction indicated by arrow B is the second direction. In addition, in this embodiment, the first direction can be the up and down direction, and the second direction can be the horizontal direction, that is, the second direction is the length direction of the reference platform 500, and the first positioning tool 600 and the second positioning tool 610 are arranged at intervals along the second direction.

[0063] Among them, a plurality of connecting holes 230 can be set on the positioning member 200, so that the positioning member 200 can be connected to the end plate 710 through bolts, and the connecting hole 230 can be set as a circular hole consistent with the hole position on the end plate 710, or the connecting hole 230 can also be set as a waist-shaped hole, so that the positioning member 200 can adapt to end plates 710 of different specifications, that is, the steel beam end plate positioning tool 1 can adapt to the assembly of steel beams 700 of different specifications.

[0064] According to the steel beam end plate positioning tool 1 of the embodiment of the utility model, by connecting one end of the positioning member 200 to the fixed frame 100, and the other end to the driving component 300 for transmission connection, the driving component 300 can be used to drive the other end of the positioning member 200 to move, and then the positioning member 200 can be rotated relative to the fixed frame 100 to adjust the angle of the positioning member 200 relative to the fixed frame 100. After the positioning member 200 is adjusted into place, the end plate 710 of the steel beam 700 is fixed to the positioning member 200, and the positioning member 200 can be used to fix the end plate 710 of the steel beam 700, so that the angle of the end plate 710 can be consistent with the angle of the main end face of the steel beam 700, and the end plate 710 can fit with the main end face of the steel beam 700, which is convenient for welding and assembly of the end plate 710 and the main body of the steel beam 700.

[0065] In addition, one end of the positioning member 200 in the first direction is rotatably connected to the first end 110 , the driving assembly 300 is disposed on the fixing frame 100 and adjacent to the second end 120 , and the driving assembly 300 is drivingly connected to the other end of the positioning member 200 in the first direction.

[0066] In this way, the driving component 300 can be closer to the second end 120 of the fixing frame 100, that is, the driving component 300 can be closer to the upper end of the fixing frame 100, so that the distance between the driving component 300 and the upper end of the positioning member 200 can be closer, and then the length of the connecting structure between the driving component 300 and the upper end of the positioning member 200 can be shortened, so that the connection stability between the driving component 300 and the positioning member 200 is higher, that is, the driving component 300 can drive the positioning member 200 to rotate more stably, and after being adjusted into place, the position of the positioning member 200 can be stably maintained unchanged, and the steel beam end plate positioning tool 1 can support the steel beam 700 more stably and reliably, effectively avoiding the instability of the connection between the driving component 300 and the positioning member 200, which is conducive to improving the accuracy of the positioning of the end plate 710 by the steel beam end plate positioning tool 1, and the assembly error between the end plate 710 and the main body of the steel beam 700 is smaller, and the assembly accuracy is higher.

[0067] In this way, the structure between the driving assembly 300 and the positioning member 200 of the steel beam end plate positioning tool 1 according to the embodiment of the utility model is more compact, which can effectively avoid the instability of the connection between the driving assembly 300 and the positioning member 200, which is beneficial to improving the positioning accuracy and making the steel beam 700 assembly accuracy higher.

[0068] According to the steel beam assembly device 2 of the embodiment of the utility model, by utilizing the steel beam end plate positioning tool 1 according to the above-mentioned embodiment of the utility model, the positioning accuracy of the end plate 710 can be improved, so that the assembly accuracy of the steel beam 700 is higher.

[0069] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the driving assembly 300 is located between the rotation axis of the positioning member 200 and the second end 120 in the first direction.

[0070] It should be noted that when adjusting the angle of the positioning member 200, the positioning member 200 can be parallel to the first direction, or the positioning member 200 can form a smaller angle with the first direction, that is, the two ends of the positioning member 200 can be adjacent to the first end 110 and the second end 120 of the fixing frame 100 respectively.

[0071] It can be understood that the upper end of the positioning member 200 is closer to the upper end of the fixing frame 100. By arranging the driving assembly 300 between the rotation axis of the positioning member 200 and the second end 120, the driving assembly 300 can be closer to the second end 120, so that the driving assembly 300 can be closer to the other end of the positioning member 200. The driving assembly 300 can drive the other end of the positioning member 200 to move, thereby causing the positioning member 200 to rotate around its rotation axis. In addition, the connection structure between the driving assembly 300 and the other end of the positioning member 200 can be shorter, which is conducive to improving the connection between the driving assembly 300 and the positioning member 200. The connection stability is improved to avoid the instability of the connection between the driving component 300 and the positioning member 200 when the positioning member 200 is subjected to the pressure of the steel beam 700, and the stability of the fixing of the positioning member 200 by the driving component 300 is further improved, that is, the driving component 300 can not only stably drive the other end of the positioning member 200 to move, but also stably fix the other end of the positioning member 200. Therefore, when the steel beam 700 is assembled, the positioning member 200 can maintain the preset angle unchanged, so that the positioning accuracy of the steel beam end plate positioning tool 1 to the end plate 710 is higher, and the assembly error of the steel beam 700 is smaller.

[0072] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the driving assembly 300 drives the other end of the positioning member 200 to move closer to or away from the fixing frame 100 along the second direction.

[0073] Specifically, the rotation axis of the positioning member 200 can be perpendicular to the first direction and the second direction, the end plate 710 can be connected to the side of the positioning member 200 that is away from the mounting frame, and the other end of the positioning member 200 is driven by the driving assembly 300 to move relative to the fixing frame 100 along the second direction, that is, the angle of the positioning member 200 relative to the first direction can be adjusted. Thus, the driving assembly 300 can drive the positioning member 200 to rotate to adjust the angle between the positioning member 200 and the first direction, so that the angle of the end plate 710 fixed to the positioning member 200 relative to the first direction can be adjusted, so that the end plate 710 can fit the end surface of the main body of the steel beam 700, and the welding connection between the end plate 710 and the main body is more stable.

[0074] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the fixing frame 100 includes a base 130 , a connecting plate 140 and a fixing seat 150 .

[0075] The base 130 is suitable for being fixed to the reference platform 500 . The connecting plate 140 extends along the first direction and one end of the connecting plate 140 is connected to the base 130 . The fixing seat 150 is connected to the connecting plate 140 and is adjacent to the other end of the connecting plate 140 . The driving assembly 300 is installed on the fixing seat 150 .

[0076] In this way, the base 130 can increase the connection area between the fixing frame 100 and the reference platform 500, so that the relative position of the fixing frame 100 and the reference platform 500 is more stable. By setting the fixing seat 150, the fixing seat 150 can construct a space for accommodating the driving component 300, which is convenient for fixing the driving component 300, and the driving component 300 can be set at a position of the connecting plate 140 close to the upper end of the positioning member 200. The driving component 300 can be closer to the upper end of the positioning member 200, thereby shortening the length of the connection structure between the driving component 300 and the positioning member 200, making the connection between the driving component 300 and the positioning member 200 more stable and reliable.

[0077] Furthermore, if Figure 2-Figure 4 As shown, the fixing seat 150 is arranged on the side of the connecting plate 140 facing away from the positioning member 200, so as to avoid position interference between the positioning member 200 and the fixing seat 150 when rotating, so as to facilitate adjustment of the angle of the positioning member 200 and make the structural setting more reasonable.

[0078] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the fixing frame 100 further includes a reinforcing plate 160 , which is disposed between the fixing seat 150 and the base 130 , and the reinforcing plate 160 is connected to at least the base 130 and the connecting plate 140 .

[0079] For example, the reinforcing plate 160 can be constructed as a triangle, and the reinforcing plate 160 is connected to the base 130 and the connecting plate 140 respectively, so that the reinforcing plate 160 can be used to strengthen the connection strength between the base 130 and the connecting plate 140, so that the structural strength of the fixing frame 100 is higher.

[0080] Alternatively, the reinforcing plate 160 can not only be connected to the base 130 and the connecting plate 140, but can also be supported under the fixing seat 150 and connected to the fixing seat 150, that is, the reinforcing plate 160 is simultaneously connected to the base 130, the connecting plate 140 and the fixing seat 150, so that the reinforcing plate 160 can not only strengthen the connection strength between the base 130 and the connecting plate 140, but also can use the reinforcing plate 160 to support the fixing seat 150, and at the same time can improve the connection strength between the fixing seat 150 and the connecting plate 140, thereby further improving the structural strength of the fixing frame 100.

[0081] In some specific embodiments of the present invention, Figure 3 As shown, the driving assembly 300 includes a screw rod 310 , a transmission member 320 and a connecting rod 330 .

[0082] The screw rod 310 is rotatably connected to the fixed seat 150 and extends along the second direction, the transmission member 320 is sleeved on the screw rod 310 and threadedly connected to the screw rod 310, one end of the connecting rod 330 is rotatably connected to the transmission member 320, and the other end of the connecting rod 330 is rotatably connected to the other end of the positioning member 200; wherein, when the positioning member 200 is rotated to be parallel to the first direction, the connecting rod 330 is perpendicular to the positioning member 200.

[0083] For example, when the screw rod 310 is rotated clockwise (or counterclockwise), the transmission member 320 can move along the axial direction of the screw rod 310 and gradually approach the connecting plate 140, so that the transmission member 320 can be used to drive the connecting rod 330 to move, and the connecting rod 330 can be used to push the upper end of the positioning member 200 to move in a direction away from the fixing frame 100, so that the angle between the positioning member 200 and the first direction gradually decreases; and when the screw rod 310 is rotated counterclockwise (or clockwise), the transmission member 320 can move along the axial direction of the screw rod 310 and gradually away from the connecting plate 140, so that the transmission member 320 can be used to drive the connecting rod 330 to move, and the connecting rod 330 can be used to pull the upper end of the positioning member 200 to move in a direction close to the fixing frame 100, so that the angle between the positioning member 200 and the first direction gradually increases.

[0084] Therefore, the positioning member 200 can be driven to rotate by the driving assembly 300 and the transmission is transmitted through the screw rod 310, so the transmission efficiency is higher and the transmission is more stable.

[0085] In some specific embodiments of the present invention, Figure 7As shown, the transmission member 320 includes a threaded portion 321 , a connecting portion 322 and a plurality of first ear plates 323 .

[0086] The threaded portion 321 is sleeved on the screw rod 310 and threadably matched with the screw rod 310 , the connecting portion 322 is connected to the outer circumference of the threaded portion 321 , a plurality of first ear plates 323 are connected to the connecting portion 322 , and one end of the connecting rod 330 is rotatably connected to the first ear plate 323 and is located between the plurality of first ear plates 323 .

[0087] Specifically, the first ear plate 323 can be provided with a small hole, and one end of the connecting rod 330 can be rotatably connected to the first ear plate 323 through a rotating shaft to realize relative rotation of the connecting rod 330 and the transmission member 320, and by arranging one end of the connecting rod 330 between multiple first ear plates 323, multiple first ear plates 323 can limit both sides of the connecting rod 330 in the thickness direction, thereby improving the connection stability of the connecting rod 330 and the transmission member 320.

[0088] In some specific embodiments of the present invention, Figure 4 As shown, the other end of the connecting plate 140 is provided with an avoidance hole 141 , and the connecting rod 330 is passed through the avoidance hole 141 .

[0089] Among them, the height of the avoidance hole 141 can be greater than the size of the connecting rod 330 in the first direction. It can be understood that when the connecting rod 330 drives the upper end of the positioning member 200 to move, the height of the upper end of the positioning member 200 will change, that is, the height of the end where the connecting rod 330 and the positioning member 200 are connected will change, and because the transmission member 320 only moves along the axial direction of the screw rod 310, that is, the height of the transmission member 320 remains unchanged, and the height of the end of the connecting rod 330 connected to the transmission member 320 remains unchanged. At this time, there will be a height difference between the two ends of the connecting rod 330, that is, the connecting rod 330 will be tilted relative to the horizontal plane, which will cause the space occupied by the connecting rod 330 in the first direction to become larger. By setting the height of the avoidance hole 141 to be larger, the position interference between the hole wall of the avoidance hole 141 and the connecting rod 330 can be avoided, so as to facilitate the movement of the connecting rod 330.

[0090] In addition, the width of the avoidance hole 141 may be greater than the thickness of the connecting rod 330 , so that the avoidance hole 141 can be prevented from over-squeezing the connecting rod 330 , so that the connecting rod 330 can easily extend and retract in the avoidance hole 141 .

[0091] In addition, the side wall of the avoidance hole 141 can also support the connecting rod 330. It can be understood that when the screw rod 310 rotates, the transmission member 320 tends to rotate along with the screw rod 310. At this time, the side wall of the avoidance hole 141 is used to support the connecting rod 330, which can limit the rotation of the connecting rod 330, thereby preventing the transmission member 320 from rotating, so that the transmission member 320 can stably drive the connecting rod 330 to move along the axial direction of the screw rod 310.

[0092] In some other specific embodiments of the present invention, the connecting rod 330 extends beyond the other end of the connecting plate 140 along the first direction, that is, the connecting rod 330 extends beyond the second end 120 of the fixing frame 100, so that the connecting plate 140 does not need to be provided with an avoidance hole 141, and when the transmission member 320 drives the connecting rod 330 to move, the connecting rod 330 will not interfere with the position of the connecting plate 140. The structure of the connecting plate 140 is simpler and convenient for processing, and it is conducive to simplifying the assembly of the steel beam end plate positioning tooling 1.

[0093] In some specific embodiments of the present invention, Figure 4 As shown, the fixing seat 150 includes a bottom plate 151 and a first side plate 152 .

[0094] The bottom plate 151 is connected to the connecting plate 140, the first side plate 152 is connected to one end of the bottom plate 151 away from the connecting plate 140, one end of the screw rod 310 is rotatably connected to the first side plate 152, and the other end of the screw rod 310 is rotatably connected to the connecting plate 140. In this way, the position of the screw rod 310 can be fixed by using the first side plate 152 and the connecting plate 140, and the bottom plate 151 can be connected to the first side plate 152 and the connecting plate 140, so that the relative position between the first side plate 152 and the bottom plate 151 is fixed.

[0095] In some specific embodiments of the present invention, Figure 5 and Figure 6 As shown, the steel beam end plate positioning tool 1 also includes a first bearing 400 and a second bearing 410 .

[0096] The first side plate 152 defines a through hole 153 , the first bearing 400 is sleeved on one end of the screw rod 310 and disposed in the through hole 153 , the connecting plate 140 defines a groove 142 , and the second bearing 410 is sleeved on the other end of the screw rod 310 and disposed in the groove 142 .

[0097] Among them, the first bearing 400 and the second bearing 410 can be thrust ball bearings. By setting the first bearing 400 and the second bearing 410, the friction between the screw rod 310 and the first side plate 152 and the connecting plate 140 can be reduced, so that the rotation of the screw rod 310 is easier and the operation of the drive assembly 300 is more stable.

[0098] Furthermore, if Figure 5 and Figure 6 As shown, the fixing seat 150 further includes a stop plate 154 . The stop plate 154 is connected to the first side plate 152 , and the stop plate 154 at least stops a side of the first bearing 400 that is away from the connecting plate 140 .

[0099] In this way, the stop plate 154 can stop the side of the first bearing 400 facing away from the connecting plate 140 to prevent the first bearing 400 from separating from the first side plate 152. At the same time, the stop plate 154 can apply a load to the first bearing 400 to enable the first bearing 400 to work normally.

[0100] In addition, it should be noted that a stop plate 154 may also be provided on the side of the first side plate 152 facing the connecting plate 140, that is, both sides of the first bearing 400 are fixed by the stop plate 154, and a stop plate 154 may also be provided on the side of the second bearing 410 facing the first side plate 152 to stop the second bearing 410.

[0101] In addition, the groove 142 on the connecting plate 140 may also be constructed as a connected structure, that is, the groove 142 passes through the connecting plate 140 . In this case, stop plates 154 are provided on both sides of the connecting plate 140 to stop the second bearing 410 .

[0102] Furthermore, if Figure 6 As shown, the distance between the stop plate 154 and the first side plate 152 is 1 mm to 2 mm. Specifically, if the distance between the side of the first side plate 152 facing away from the connecting plate 140 and the connecting plate 140 is D1, and after the screw rod 310 is installed in place, the distance between the side of the first bearing 400 facing away from the connecting plate 140 and the connecting plate 140 is D2, that is, the difference between D2 and D1 needs to be between 1 mm and 2 mm.

[0103] It should be noted that, in the present embodiment, the first bearing 400 and the second bearing 410 are both thrust ball bearings. A gap is provided between the stop portion and the first side plate 152 to ensure that the stop plate 154 can stop against the first bearing 400 , i.e., to avoid the stop plate 154 being unable to apply pressure to the first bearing 400 after contacting the first side plate 152 .

[0104] In this way, it can be ensured that after the stop part is assembled, the stop plate 154 can be used to apply the minimum axial load required for work to the first bearing 400, so that the first bearing 400 and the second bearing 410 can work normally, and the first bearing 400 or the second bearing 410 can be prevented from separating, so as to ensure the internal lubrication and sealing performance of the first bearing 400 and the second bearing 410, and prevent the first bearing 400 and the second bearing 410 from jumping or vibrating during rotation, which is beneficial to improve the load-bearing capacity and service life of the first bearing 400 and the second bearing 410.

[0105] The distance between the stop plate 154 and the first side plate 152 is no greater than 2 mm, which can prevent the bolts used to connect the stop plate 154 and the first side plate 152 from being too long, thereby ensuring that the connection structure between the stop plate 154 and the first side plate 152 can be more stable.

[0106] In some specific embodiments of the present invention, Figure 6 As shown, a first stop step 311 is provided at one end of the screw rod 310 and a second stop step 312 is provided at the other end. The first stop step 311 stops at the side of the first bearing 400 facing the connecting plate 140, and the second stop step 312 stops at the side of the second bearing 410 facing away from the connecting plate 140.

[0107] In this way, after the screw rod 310 is assembled, the first stop step 311 can stop the side of the first bearing 400 facing the connecting plate 140, that is, the first stop step 311 and the stop plate 154 can respectively stop the two axial sides of the first bearing 400 to apply a bearing load to the first bearing 400 so that the first bearing 400 can work normally. At the same time, the second stop step 312 can stop the side of the second bearing 410 facing away from the connecting plate 140, that is, the second stop step 312 and the bottom wall of the groove 142 can respectively stop the two axial sides of the second bearing 410 to apply a bearing load to the second bearing 410 so that the second bearing 410 can work normally.

[0108] In some specific embodiments of the present invention, Figure 4 As shown, the fixing base 150 further includes a plurality of second side plates 155 .

[0109] The second side plates 155 are connected to the bottom plate 151 , and two ends of the second side plates 155 are respectively connected to the end of the first side plate 152 and the connecting plate 140 . The screw rod 310 and the transmission member 320 are located between the plurality of second side plates 155 .

[0110] By setting up multiple second side plates 155, multiple second side plates 155 can assist in connecting the first side plate 152 and the connecting plate 140, which is beneficial to improving the connection strength between the first side plate 152 and the connecting plate 140. The strength of the fixing seat 150 is higher, and the overall structural strength of the fixing frame 100 is higher. The fixing of the fixing frame 100 to the driving component 300 is more stable and reliable, which effectively avoids the shaking of the driving component 300. The driving component 300 can more stably and reliably drive the positioning member 200 to rotate.

[0111] In some specific embodiments of the present invention, the steel beam end plate positioning tool 1 also includes a guide plate (not shown in the figure), which is connected to the opposite sides of the transmission member 320 and can be slidably stopped at the second side plate 155; or, the guide plate is connected to the transmission member 320 and can be slidably stopped at the bottom plate 151.

[0112] For example, a guide groove may be provided on the second side plate 155 or the bottom plate 151, and a side of the guide plate away from the transmission member 320 may be slidably fitted in the guide groove, so that the guide groove may limit the guide plate to slide along the extension direction of the guide groove.

[0113] It should be noted that when the screw rod 310 rotates, the transmission member 320 has a tendency to rotate along with the screw rod 310. By setting a guide plate and using the guide plate and the second side plate 155 or the bottom plate 151 for stopping, no relative rotation will occur between the guide plate and the fixed seat 150, so that the transmission member 320 can be prevented from rotating relative to the fixed seat 150, that is, the transmission member 320 does not rotate along with the screw rod 310. When the screw rod 310 rotates, the transmission member 320 can only move along the axial direction of the screw rod 310, and then the transmission member 320 and the connecting rod 330 can be used to drive the upper end of the positioning member 200 to approach or move away from the fixed frame 100 along the second direction, so that the positioning member 200 can rotate to adjust the angle.

[0114] In some specific embodiments of the present invention, Figure 2 , Figure 3 and Figure 5 As shown, the driving assembly 300 further includes a rotating hand wheel 340, one end of the screw rod 310 is inserted into the fixing seat 150, and the rotating hand wheel 340 is connected to one end of the screw rod 310, so that the screw rod 310 is rotated by rotating the rotating hand wheel 340. In this way, when the angle of the positioning member 200 needs to be adjusted, the screw rod 310 can be driven to rotate by rotating the rotating hand wheel 340, which is more labor-saving and easy to operate.

[0115] In some specific embodiments of the present invention, Figure 2 , Figure 3 and Figure 8 As shown, the positioning member 200 is provided with a plurality of second ear plates 210 , and the plurality of second ear plates 210 are adjacent to the other end of the positioning member 200 . The other end of the connecting rod 330 is rotatably connected to the second ear plates 210 and is located between the plurality of second ear plates 210 .

[0116] In this way, the multiple second ear plates 210 can stop the opposite sides of the connecting rod 330 to limit the position between the connecting rod 330 and the positioning member 200. The connection between the other end of the connecting rod 330 and the multiple second ear plates 210 is more stable and less prone to damage, which is beneficial to improving the connection stability between the connecting rod 330 and the positioning member 200 and can extend the service life of the steel beam end plate positioning tooling 1.

[0117] In some specific embodiments of the present invention, Figure 2 , Figure 3 and Figure 8As shown, the positioning member 200 is provided with a plurality of third ear plates 220, and the plurality of third ear plates 220 are adjacent to one end of the positioning member 200, and the fixing frame 100 is provided with a fourth ear plate 143, and the fourth ear plate 143 is adjacent to the first end 110, and the fourth ear plate 143 is rotatably connected to the third ear plates 220 and is located between the plurality of third ear plates 220.

[0118] In this way, the multiple fourth ear plates 143 can stop the opposite sides of the third ear plate 220 to limit the position between the connecting plate 140 and the positioning member 200. The connection between the third ear plate 220 and the multiple fourth ear plates 143 is more stable and less prone to damage, which is beneficial to improving the connection stability between the connecting plate 140 and the positioning member 200 and can extend the service life of the steel beam end plate positioning tooling 1.

[0119] In some specific embodiments of the present invention, when the positioning member 200 rotates relative to the fixing frame 100, the angle between the positioning member 200 and the first direction is A, wherein the angle A satisfies: 0°≤A≤11°.

[0120] Among them, in this embodiment, the first direction is the vertical direction, and when the upper end of the positioning member 200 is rotated to the extreme position in the direction away from the fixing frame 100, the angle between the positioning member 200 and the first direction is 0°, that is, the positioning member 200 will not tilt in the direction away from the fixing frame 100, and when the positioning member 200 is rotated to the extreme position in the direction close to the fixing frame 100, the angle between the positioning member 200 and the first direction will not exceed 11°. This can meet the production of most steel beams 700 with slopes, and can also meet the production of steel beams 700 without slopes, and has stronger applicability.

[0121] Moreover, with such an arrangement, a "large at the top and small at the bottom" structure can be formed between the positioning piece 200 of the first positioning fixture 600 and the positioning piece 200 of the second positioning fixture 610, so that the steel beam end plate positioning fixture 1 can adjust the positioning piece 200 to a suitable angle, and then the positioning piece 200 can be used to fix the end plate 710 to a suitable angle, so as to facilitate the welding of the end plate 710 and the main body of the steel beam 700.

[0122] In addition, it should be noted that, if for some special steel beams 700, or if the assembly method of the steel beam 700 is adjusted, the positioning member 200 can also be arranged to be rotated in a direction away from the fixing frame 100 to be tilted, that is, the positioning member 200 of the first positioning fixture 600 and the positioning member 200 of the second positioning fixture 610 can also form a "small on top and large on bottom" structure, and the rotation angle of the positioning member 200 can be adjusted according to actual conditions.

[0123] Other structures and operations of the steel beam end plate positioning tool 1 and the steel beam assembly device 2 having the same according to the embodiment of the utility model are well known to ordinary technicians in this field and will not be described in detail here.

[0125] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
