Description

Technical Field

[0001] The invention relates to the technical field of steel frame structure processing, and in particular to a bridge steel frame structure processing platform. Background Art

[0002] Bridge steel frame refers to a beam made of steel. It is the main structural support of the bridge and fully plays the role of bearing capacity. This steel frame is often used for bridge deck paving and can withstand the pressure of vehicles and pedestrians without causing obvious deformation due to external forces. The crossbeam is one of the key components used to connect the steel frames of the bridge on both sides. The crossbeam can assist in the support of the steel frame bridges on both sides, thereby improving the bearing capacity of the steel frame bridge.

[0003] The crossbeam is usually provided with two sections, and the two sections of the crossbeam are connected by a mounting plate and an inclined rod (such as Fig. 9 To ensure the connection strength of the two beams, the mounting plates on the two beams need to be welded and fixed to the corresponding beams in an alternating manner (as shown in the figure). Figure 8 As shown), the inclined rod improves the connection strength between the beams on both sides through the principle of isosceles triangle.

[0004] At present, the following problems mainly exist when welding the mounting plates on the two beams: before welding, a single beam is first fixed, and then a number of mounting plates and the beam are limited and welded in turn. The welding method of a single beam and the mounting plate needs to ensure the relative position between the mounting plates. Therefore, the mounting plates need to be adjusted repeatedly before welding, which affects the welding efficiency. In addition, if the mounting plates on the two beams are used as a group and there is a misalignment, the tilt degree of the tilt rod will be different when the tilt rod is fixed. Summary of the invention

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-9 The present application is further described in detail.

[0032] Please refer to Figure 1 , Figure 3 and Figure 4 A bridge steel frame structure processing platform includes a rectangular seat 1 with an installation groove 11 provided inside, and a clamping mechanism 2 for clamping and fixing a crossbeam 6 is symmetrically arranged on the upper surface of the rectangular seat 1. A supporting mechanism 3 for supporting a mounting plate 7 is arranged on each of the two clamping mechanisms 2, and a limiting mechanism 4 for limiting the mounting plate 7 is arranged between the two clamping mechanisms 2. A driving mechanism 5 for driving the two clamping mechanisms 2 to move closer to or away from each other is arranged inside the installation groove 11.

[0033] During operation, firstly, the two cross beams 6 are placed on the two clamping mechanisms 2, and then the distance between the two cross beams 6 is adjusted by the driving mechanism 5. After the adjustment is completed, the cross beam 6 is limited and fixed from the front and rear ends by the two clamping mechanisms 2. Then, several mounting plates 7 to be welded are placed on the supporting mechanisms 3 respectively and the several mounting plates 7 are limited and fixed by the limiting mechanisms 4. Then, the supporting mechanisms 3 are controlled to drive the mounting plates 7 on both sides to move and complete the alignment during the movement. Finally, the mounting plates 7 on both sides that have completed the alignment are welded and fixed to the cross beams 6 by external welding equipment.

[0034] Please refer to Figure 6 The upper surface of the rectangular seat 1 is provided with two strip-shaped slide grooves 12 facing downward, and the two strip-shaped slide grooves 12 are respectively located on the left and right sides of the driving mechanism 5 .

[0035] Please refer to Figure 1 and Figure 3 The clamping mechanism 2 includes a supporting platform 21, a side wall of the supporting platform 21 close to the limiting mechanism 4 is provided with a guide rail 211 and the supporting platform 21 is located on the upper surface of the rectangular seat 1, and clamping blocks 22 are symmetrically arranged at the front and rear ends of the supporting platform 21, the two clamping blocks 22 are slidably arranged on the upper surface of the rectangular seat 1, and the front end surface of the rear clamping block 22 is fixedly connected to the supporting platform 21 through a connecting rod, the front end surface of the rear clamping block 22 is also provided with a square groove 221 from front to back, and the rear end surface of the front clamping block 22 is also provided with a square groove 221 from back to front, and the two clamping blocks 22 are also provided with baffles 23, and the baffles 23 are located on the side of the clamping block 22 close to the limiting mechanism 4.

[0036] Please refer to Figure 3 The clamping mechanism 2 also includes a screw 24, which slides through the front clamping block 22 and is fixedly connected to the front end surface of the support platform 21. The outer wall of the screw 24 is threadedly connected with an adjusting nut 25, and the adjusting nut 25 is in contact with the front end surface of the clamping block 22.

[0037] Please refer to Figure 4 The driving mechanism 5 rotates the gear 52 installed at the bottom of the mounting groove 11, and racks 53 are provided at the front and rear ends of the gear 52. The two racks 53 are meshed with the gear 52 for transmission. A connecting block 54 is vertically provided at one end of the two racks 53 away from the gear 52. The two connecting blocks 54 pass through the strip slide 12 and are fixedly connected to the corresponding lower end surfaces of the supporting platform 21 respectively. The gear 52 is driven by an external reciprocating motor.

[0038] During operation, first place the two beams 6 on the upper surfaces of the two supporting platforms 21 respectively, and then gradually screw the adjusting nuts 25 backwards. At this time, the two supporting platforms 21 on the front side will slide backwards and gradually approach the beam 6 driven by the adjusting nuts 25. The front end of the beam 6 is inserted into the square groove 221 of the front clamping block 22 and is continued to be pushed backwards by the clamping block 22 until the front and rear ends of the beam 6 are tightened by the square grooves 221 of the front and rear clamping blocks 22.

[0039] When the two beams 6 have completed the limit fixation at the front and rear ends, the reciprocating motor is started to drive the gear 52 to rotate and mesh with the racks 53 on the front and rear sides. The racks 53 on the front and rear sides move away from each other under the drive of the gear 52. At this time, the support platforms 21 on both sides also move away from each other under the drive of the connecting blocks 54 until they move to the required position for processing.

[0040] It should be noted that the baffles 23 arranged on the left and right clamping blocks 22 are both close to the limiting mechanism 4, that is, the baffles 23 on the two left clamping blocks 22 are arranged on the right end surface of the clamping block 22, and the baffles 23 on the two right clamping blocks 22 are arranged on the left end surface of the clamping block 22. This design can limit the crossbeam 6 when the crossbeam 6 is initially placed, thereby ensuring that the relative positions of the crossbeams 6 on both sides are consistent and parallel.

[0041] Please refer to Figure 5 and Figure 7 The supporting mechanism 3 includes an electric slider 31 and two linkage sliders 32. The electric slider 31 and the linkage sliders 32 are both slidably arranged inside the guide rail 211, and the electric slider 31 and the linkage slider 32 are fixedly connected by a connecting plate 33, and the two linkage sliders 32 are also fixedly connected by a connecting plate 33. A support platform 34 is fixedly arranged on the electric slider 31 and the linkage slider 32. The support platform 34 is divided into two parts, the upper half of the support platform 34 is used to support the mounting plate 7, and the lower half of the support platform 34 is used to align the mounting plates 7 on both sides. Two groups of vertical plates 35 are symmetrically arranged on the upper surface of the upper half of the support platform 34, and each group of vertical plates 35 includes two vertical plates 35. The two vertical plates 35 in the same group are connected by a spring, and the vertical plates 35 close to the edge of the same group are fixedly connected to the support platform 34.

[0042] Please refer to Figure 1 and Figure 6 The limiting mechanism 4 includes a U-shaped frame 41. The U-shaped frame 41 has an opening facing downward and is fixedly provided with a double-shaft motor 42 in the middle in the left-right direction. Threaded lead screws 43 are fixedly provided at both the left and right output ends of the double-shaft motor 42. The two threaded lead screws 43 have opposite helix directions. Slide rods 44 are symmetrically arranged on the front and rear sides of the double-shaft motor 42. The two slide rods 44 are arranged in the left-right direction and penetrate through the U-shaped frame 41. L-shaped plates 45 are arranged on the left and right sides of the U-shaped frame 41.

[0043] Please refer to Figure 6 There are two L-shaped plates 45, which are arranged symmetrically left and right. The middle parts of the two L-shaped plates 45 are relatively positioned and are respectively threadedly connected to the left and right threaded lead screws 43, and the front and rear ends are slidably arranged on the outer walls of the two slide rods 44. A plurality of upwardly circular grooves are formed in the side wall of the L-shaped plate 45 away from the U-shaped frame 41 in the front-rear direction, and roller shafts 46 are rotatably arranged in the circular grooves. A plurality of left-to-right arc-shaped grooves are formed in the upper and lower end surfaces of the horizontal section of the L-shaped plate 45 in the front-rear direction, and roller shafts 46 are also rotatably arranged in the arc-shaped grooves.

[0044] After the two cross beams 6 are limited and fixed, a plurality of mounting plates 7 are respectively placed between the two sets of vertical plates 35 of the two side support platforms 34, and the mounting plates 7 are tightly pressed and limited by the self-adaptive force of the two sets of vertical plates 35. Then, the double-shaft motor 42 is started to drive the left and right threaded lead screws 43 to rotate. At this time, the left and right L-shaped plates 45 move in the left and right directions respectively under the drive of the threaded lead screws 43 and gradually insert into the left and right plurality of mounting plates 7 until the two side mounting plates 7 are closely attached to the cross beam 6.

[0045] It should be noted that when the plurality of roller shafts 46 arranged on the horizontal section of the L-shaped plate 45 are working, the multi-degree-of-freedom tight pressing and limiting of the mounting plate 7 can be realized first by the rotation of the threaded lead screw 43. At the same time, the roller shafts 46 rotatably arranged on the L-shaped plate 45 can reduce the friction between the L-shaped plate 45 and the mounting plate 7, ensuring that the mounting plate 7 will not be unable to move due to excessive friction when being driven by the electric slider 31 later. At the same time, the electric sliders 31 and the two linkage sliders 32 arranged inside the left and right guide rails 211 are relatively positioned, that is, the left electric slider 31 and the two linkage sliders 32 are arranged at the rear end of the guide rail 211, and the right electric slider 31 and the two linkage sliders 32 are arranged at the front end of the guide rail 211.

[0046] Please refer to Figure 5 and Figure 7The lower half of the support platform 34 is an isosceles trapezoid, and the side walls of the support platforms 34 on the linkage sliders 32 on both sides are both provided with spring telescopic rods 321 along the left and right directions. The spring telescopic rods 321 on the left and right sides are located at different heights, and the ends of the two spring telescopic rods 321 on each side have different shapes, that is, one spring telescopic rod 321 is rectangular, and the other spring telescopic rod 321 is hexagonal.

[0047] Please refer to Figure 3 and Figure 7 The electric sliders 31 arranged in the two guide rails 211 move in opposite directions, that is, the left electric slider 31 and the two linked sliders 32 slide from back to front, and the right electric slider 31 and the two linked sliders 32 slide from front to back, and the electric slider 31 is always located in front of the moving direction of the two linked sliders 32.

[0048] Please refer to Figure 4 and Figure 5 A rectangular groove 212 and a hexagonal groove 213 are provided on the side walls of the supporting platform 21 on both sides for matching the spring telescopic rod 321. The rectangular groove 212 and the hexagonal groove 213 are both funnel-shaped, that is, the opening gradually decreases from left to right.

[0049] When several mounting plates 7 on the left and right sides are pressed against the limit position, the electric sliders 31 on both sides are synchronously controlled to drive the support platform 34 and the mounting plate 7 to move relative to each other. When the mounting plate 7 moves, it will drive the roller shaft 46 set on the L-shaped plate 45 to rotate, thereby reducing the friction generated when the mounting plate 7 moves. When the support platforms 34 on both sides move relative to each other, the two spring telescopic rods 321 of different shapes will cooperate with the isosceles trapezoidal surface of the lower half of the support platform 34 and retract and extend. When the spring telescopic rods 321 of different shapes on both sides are respectively inserted into the rectangular grooves 212 or hexagonal grooves 213 that match themselves, the alignment work of the mounting plates 7 on both sides is completed. Then, the connection between the mounting plate 7 and the crossbeam 6 is welded and fixed by external welding equipment. Finally, the tilting rods are cross-placed between the mounting plates 7 in the form of an isosceles triangle and fixed by bolts and nuts.

[0050] It should be noted that the rectangular groove 212 and the hexagonal groove 213 divide the corresponding guide rail 211 into three sections, and the rectangular grooves 212 and the hexagonal grooves 213 on the two guide rails 211 are staggered. Therefore, when the corresponding spring telescopic rod 321 is respectively inserted into the rectangular groove 212 and the hexagonal groove 213, it means that the mounting plate 7 corresponding to the spring telescopic rod 321 is located at the center of the two adjacent mounting plates 7 on the opposite side.

[0051] In the description of the embodiments of the present invention, it should be noted that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention. In addition, in the description of the present invention, unless otherwise specified, "multiple", "multiple roots", and "multiple groups" mean two or more.

[0052] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
