Further, during the assembly of the girder machine, the supporting rod 71 is placed inside the fixing device 6, and the lifting device 7 is restrained and fixed by the fixing device 6.
Under the circumstances such as the transfer of the girder machine, the girder machine needs to be disassembled and assembled, in order to facilitate the disassembly and assembly of the girder machine by the staff, as shown in fig. 4, the fixing device 6 comprises a fixing plate 61, the fixing plate 61 is fixedly installed at the upper end of the second support frame 2, the two sides of the outer surface of the fixing plate 61 are provided with U-shaped rods 62, the upper ends of the two U-shaped rods 62 are provided with limiting rods 621, the lower parts of the two U-shaped rods 62 are slidably installed with supporting mechanisms 63, and the two sides of the upper end of the supporting mechanisms 63 are slidably installed with limiting mechanisms 64.
Specifically, during the process of assembling the beam lifter, the supporting rod 71 needs to be lifted to the upper end of the supporting mechanism 63 by a crane, when the supporting rod 71 is placed at the upper end of the supporting mechanism 63 by the crane, the supporting rod 71 is slowly put down by the crane, during the process, the supporting rod 71 can press the supporting mechanism 63 to move downwards, and during the process of moving the supporting mechanism 63 downwards, the two limiting mechanisms 64 at the upper end of the supporting mechanism are driven to move downwards.
Further, when the two limiting mechanisms 64 move downwards along with the supporting mechanism 63, the two limiting mechanisms 64 move towards one side close to each other under the action of the two limiting rods 621, after the surfaces of the two limiting mechanisms 64 are contacted with the surface of the supporting rod 71, the two limiting mechanisms 64 can clamp the supporting rod 71 so as to limit the supporting rod 71, then the driven mechanism 8 can drive the limiting mechanism 64 at the upper end of the second supporting frame 2 to fix the lifting device 7, and the limiting mechanism 64 at the upper end of the first supporting frame 1 completes the fixing work of the supporting rod 71 when contacting with the outer surface of the supporting rod 71.
In the process of installing the lifting device 7 at the upper ends of the first support frame 1 and the second support frame 2, in order to support the lifting device 7, simultaneously, in order to adapt to the span adjustment between the first support frame 1 and the second support frame 2 later, as shown in fig. 5, the supporting mechanism 63 comprises a supporting plate 631, the supporting plate 631 is slidably mounted on the inner walls of the two U-shaped rods 62, two mounting grooves 632 are formed in the middle of the upper end of the supporting plate 631, a plurality of supporting rollers 633 are rotatably mounted in inner cavities of the two mounting grooves 632, the upper parts of the outer surfaces of the plurality of supporting rollers 633 extend to the outer parts of the mounting grooves 632, two sliding grooves 634 are formed in two sides of the upper end of the supporting plate 631, a supporting block 635 is arranged in the middle of the lower end of the supporting plate 631, and two springs 636 are arranged on two sides of the lower end of the supporting block 635.
Specifically, when the supporting rod 71 is placed on the upper end of the supporting plate 631, the supporting rod 71 contacts with the outer surface of the supporting roller 633, and the plurality of supporting rollers 633 are provided here firstly to support the supporting rod 71 and secondly to prepare for adjusting the distance between the first supporting frame 1 and the second supporting frame 2 later, so that abrasion between the supporting rod 71 and the supporting plate 631 is prevented when the distance is adjusted.
Further, when the support plate 631 moves downward under the driving of the supporting rod 71, the first spring 636 is compressed, and when the support plate 631 moves downward for a certain distance, the support block 635 can support the support plate 631, so as to avoid deformation caused by excessive stress of the first spring 636.
Further, when the supporting rod 71 is removed from the upper end of the supporting plate 631, the first spring 636 pushes the supporting plate 631 to move upwards, so that the supporting plate 631 drives the two limiting mechanisms 64 to return to the initial positions.
After the lifting device 7 is placed at the upper end of the supporting mechanism 63, in order to limit and fix the lifting device 7, as shown in fig. 6, the limiting mechanism 64 comprises a triangular block 641, the lower part of the triangular block 641 is slidably connected with the inner cavity surface of the sliding groove 634, a chute 642 is formed in the middle of the outer surface of the triangular block 641 in a penetrating manner, the chute 642 is parallel to the inclined surface of the triangular block 641, the chute 642 is matched with the limiting rod 621, two hydraulic telescopic rods 643 are arranged at the upper end of the triangular block 641, two limiting rollers 644 are arranged on one side, close to the supporting roller 633, of the outer surface of the triangular block 641, and the limiting rollers 644 are matched with the limiting frame 75.
Further, as shown in fig. 7 and 8, the four fixing devices 6 at the upper end of the first support frame 1 are different from the two fixing devices 6 at the upper end of the second support frame 2 in that: the middle part of the upper end of the supporting plate 631 in the fixing device 6 at the upper end of the supporting frame one 1 is not provided with a mounting groove 632, and is not provided with a supporting roller (633) mounted in the inner cavity of the mounting groove (632), the upper end of the triangular block 641 in the fixing device 6 at the upper end of the supporting frame one 1 is not provided with a hydraulic telescopic rod 643, but the upper end of the triangular block 641 in the fixing device 6 at the upper end of the supporting frame one 1 is slidably provided with two elastic telescopic rods 645.
Further, the elastic telescopic rod 645 in the fixing device 6 at the upper end of the first support frame 1 is matched with the limiting hole 73, and the hydraulic telescopic rod 643 in the fixing device 6 at the upper end of the second support frame 2 is matched with the fixing hole 74.
Specifically, since the triangular block 641 is slidably connected with the inner cavity surface of the chute 634, and the stop lever 621 is attached to the inner cavity surface of the chute 642, and meanwhile, the chute 642 is parallel to the inclined surface of the triangular block 641, when the triangular block 641 moves downward along with the support plate 631, the two triangular blocks 641 at the upper end of the support plate 631 move to the side close to each other, when the support plate 631 moves downward to the corresponding position, the two stop rollers 644 on the outer surface of the triangular block 641 contact with the outer surface of the strut 71, and the stop rollers 644 also act to prepare for the subsequent adjustment of the span between the first support frame 1 and the second support frame 2, and meanwhile, the lower end of the stop rollers 644 does not contact with the inner side surface of the stop frame 75, but the distance between the two is small, so that the stop rollers 644 can limit the strut 71.
Further, after the limiting roller 644 contacts with the surface of the supporting rod 71, the driven mechanism 8 drives the two hydraulic telescopic rods 643 at the upper end of the triangular block 641 to enter the inner cavities of the corresponding fixing holes 74, so that the fixing device 6 fixes the lifting device 7.
Further, in the process that the strut 71 contacts the limiting mechanism 64 at the upper end of the first support frame 1, the elastic telescopic rod 645 on the limiting mechanism 64 contacts the outer surface of the strut 71, at this time, the elastic telescopic rod 645 is not aligned with the limiting hole 73, so when the strut 71 continues to move downwards, the elastic telescopic rod 645 is contracted, the spring inside the elastic telescopic rod 645 is compressed, when the strut 71 is placed at the corresponding position, after the elastic telescopic rod 645 is aligned with the limiting hole 73, the spring in the inner cavity of the elastic telescopic rod 645 pushes the elastic telescopic rod 645 to stretch, so that the elastic telescopic rod 645 enters the inner cavity of the corresponding limiting hole 73, and the fixing device 6 at the upper end of the first support frame 1 limits the strut 71.
Further, when the support rod 71 needs to be removed, the support rod 71 pulls the elastic telescopic rod 645 at the upper end of the support frame 1 to move upwards, and when the limiting mechanism 64 moves towards the initial position under the driving of the supporting mechanism 63, the elastic telescopic rod 645 gradually breaks away from contact with the inner cavity surface of the limiting hole 73.
Further, since the span between the first support frame 1 and the second support frame 2 is adjusted only by moving the second support frame 2, the fixing device 6 at the upper end of the first support frame 1 is not required to be provided with the mounting groove 632 and the support roller 633.
In order to drive the limiting mechanism 64 to fix the lifting device 7, as shown in fig. 9, the driven mechanism 8 comprises a hydraulic cylinder 81 and a hydraulic cylinder one 82, the hydraulic cylinder 81 is fixedly mounted at the middle part of the upper end of the support frame two 2, the hydraulic cylinder one 82 is fixedly mounted at the middle part of the upper end of the hydraulic cylinder 81, the output end of the hydraulic cylinder one 82 extends to the inside of the hydraulic cylinder one 82, two pistons 85 are arranged at the middle part of the inner cavity of the hydraulic cylinder 81, hydraulic oil is filled between the two pistons 85, the middle part of the upper end of the piston 85 positioned at the upper part is fixedly connected with the output end of the hydraulic cylinder one 82, a connecting frame 87 is arranged at the lower part of the hydraulic cylinder 81, the upper end of the connecting frame 87 extends to the inside of the hydraulic cylinder 81, the upper end of the connecting frame 87 is fixedly connected with the middle part of the lower end of the piston 85 positioned at the lower part, one side of the outer surface of the hydraulic cylinder 81, which is far away from the lifting mechanism 72, is provided with a hydraulic pipe one 83, the connecting position of the hydraulic pipe one 83 and the hydraulic cylinder 81 is positioned between the two pistons 85, the hydraulic pipe one 83 is communicated with the inner cavity of the hydraulic cylinder 81, and one end of the hydraulic pipe 83, which is far away from the lifting mechanism 72, is provided with four hydraulic pipes 84.

Specifically, after the limiting mechanism 64 contacts the surface of the strut 71, the first hydraulic cylinder 82 outputs to drive the piston 85 located at the upper side to move downward, so that the piston 85 located at the upper side guides hydraulic oil in the inner cavity of the hydraulic cylinder 81 into the inner cavity of the hydraulic telescopic rod 643 through the first hydraulic pipe 83 and the second hydraulic pipes 84, so that the hydraulic telescopic rod 643 enters the inner cavity of the corresponding fixing hole 74, and the hydraulic telescopic rod 643 fixes the strut 71.

Further, in the process that the second hydraulic cylinder 52 drives the moving mechanism 55 to move downwards, the connecting frame 87 fixedly connected with the supporting handle 54 drives the piston 85 located at the lower part in the inner cavity of the hydraulic cylinder 81 to move downwards, when the piston 85 moves downwards, hydraulic oil in the inner cavities of eight hydraulic telescopic rods 643 in two fixing devices 6 at the upper end of the second supporting frame 2 can be sucked into the inner cavity of the hydraulic cylinder 81 again, so that the hydraulic telescopic rods 643 are not contacted with the inner cavity surfaces of the corresponding fixing holes 74 any more, and the fixing state of the fixing devices 6 at the upper end of the second supporting frame 2 to the supporting rods 71 is released, so that when the moving mechanism 55 drives the second supporting frame 2 to move, the fixing devices 6 cannot influence the movement of the second supporting frame 2.
Further, when the transmission device 5 lifts the second support frame 2 upwards, the second support frame 2 is higher than the first support frame 1, so that the supporting rod 71 is inclined by a certain angle, but the first support frame 1 is not inclined, and when the second support frame 2 moves, the supporting roller 633 in the fixing device 6 at the upper end of the second support frame 2 contacts with the surface of the supporting rod 71, so that abrasion between the supporting rod 71 and the supporting plate 631 is not caused, and meanwhile, the limiting roller 644 has such an effect.
Further, when the second support frame 2 moves, the supporting rod 71 is inclined, and the elastic telescopic rod 645 can limit the supporting rod 71 to prevent the supporting rod 71 from sliding relatively to the first support frame 1.
Further, the transmission mechanism 56 is composed of a motor, two bevel gear sets and a transmission rod, the motor in the transmission mechanism 56 drives the transmission shaft 57 to rotate through the bevel gear sets and the transmission rod, so that the transmission shaft 57 drives the two moving mechanisms 55 to rotate, which is the prior art, and the description is omitted.
