[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Existing bridge replacement technologies include cross-line gantry crane replacement and under-line elevated trolley replacement. Both methods typically use a balance beam to balance the load, which evenly distributes the weight of the bridge and improves the stability of lifting. However, since the balance beam cannot be fixed during operation, its swaying can cause a high operational risk.

[0032] Therefore, this embodiment provides a balance beam limiting device that can limit the balance beam during operation, prevent the balance beam from shaking, and ensure operational safety.

[0033] The equalization beam limiting device provided in this embodiment can initially limit the equalization beam by closely adhering to the bottom of the equalization beam, and can also press against the side wall of the equalization beam to further strengthen the limiting, so as to completely limit the equalization beam during operation.

[0034] Specifically, please refer to Figure 1 The equalizing beam limiting device includes two hangers 1 spaced apart along a first direction, which is the length direction of the equalizing beam 10. Each hanger 1 is connected to a support leg suspension 2. The height of the support leg suspension 2 is adjustable. When parking, the height of the support leg suspension 2 is adjusted so that the support leg suspension 2 is close to the bottom of the equalizing beam 10, thus initially limiting the equalizing beam 10.

[0035] For example, please refer to Figure 2 The suspension bracket 1 includes a suspension plate 11 and two connecting plates 12. The two connecting plates 12 are arranged opposite each other and are installed on the beam changing equipment. The suspension plate 11 connects the two connecting plates 12 and is used to connect the outrigger suspension 2.

[0036] Please continue reading. Figure 2 The outrigger suspension 2 includes a horizontal bar 21, a vertical bar 22, and a support roller 23. The horizontal bar 21 is installed below the suspension base 1 along a second direction, and the vertical bars 22 are connected to both sides of the horizontal bar 21 along the second direction. The support roller 23 is also arranged along the second direction, and its two ends are fixed to the opposite side of the two vertical bars 22. The support roller 23 is used to press against the bottom of the equalizing beam 10. In this embodiment, the second direction is the width direction of the equalizing beam 10, that is, the second direction is perpendicular to the first direction.

[0037] Optionally, the horizontal bar 21 has pre-drilled screw holes at both ends in the second direction. A screw is then passed through the vertical bar 22 to further align with the screw holes at the ends of the horizontal bar 21 and screw them in, thereby achieving the connection between the horizontal bar 21 and the vertical bar 22.

[0038] Specifically, the idler roller 23 includes a connecting rod 231 and a rotating drum 232. The two ends of the connecting rod 231 are fixed to two vertical rods 22, and the rotating drum 232 is rotatably sleeved on the outer wall of the connecting rod 231, serving to press against the bottom of the equalizing beam 10. Further, two fixing rings 233 are sleeved on the outer wall of the connecting rod 231, fixed to the connecting rod 231, and abutting against the two ends of the rotating drum 232 to prevent displacement of the rotating drum 232.

[0039] In this embodiment, the height of the outrigger suspension 2 is adjustable, that is, the distance between the crossbar 21 and the suspension base 1 is adjustable. When parking, by adjusting the distance between the crossbar 21 and the suspension base 1, the idler roller 23 is pressed against the bottom of the equalizer beam 10, thus initially limiting the equalizer beam 10.

[0040] Please see Figure 2 and Figure 3The outrigger suspension 2 provided in this embodiment also includes an adjustment unit, which connects the suspension plate 11 and the crossbar 21, and further adjusts the distance between the crossbar 21 and the suspension plate 11. For example, the adjustment unit includes several adjusting screws 24, which connect the crossbar 21 and the suspension plate 11, and adjusting the adjusting screws 24 adjusts the distance between the crossbar 21 and the suspension plate 11.

[0041] This embodiment provides two installation structures for adjusting the top screw 24, both of which can realize the connection between the crossbar 21 and the hanging plate 11 and the adjustment of the distance between them. Optionally, several blind holes are opened at corresponding intervals on the top of the crossbar 21, and pre-embedded nuts are embedded in the blind holes. Nuts are fixed on the top of the hanging plate 11, and adjusting screws 24 are screwed to the nuts and pass through the hanging plate 11. The bottom of adjusting screws 24 is then screwed to the corresponding pre-embedded nuts. With the above settings, in the parking state, the distance between the crossbar 21 and the hanging plate 11 is adjusted by turning the adjusting screws 24, so that the idler roller 23 is close to the bottom of the equalizing beam 10, and the equalizing beam 10 is initially limited. Alternatively, several threaded holes are opened at corresponding intervals on the top of the crossbar 21, and nuts are fixed on the top of the hanging plate 11. Adjusting screws 24 are screwed to the nuts and pass through the hanging plate 11, and the bottom of adjusting screws 24 is then screwed to the corresponding threaded holes. With the above settings, in the parking state, the distance between the crossbar 21 and the hanging plate 11 is adjusted by turning the adjusting screws 24, so that the idler roller 23 is close to the bottom of the equalizing beam 10, and the equalizing beam 10 is initially limited.

[0042] Further, please refer to Figure 1 and Figure 4 The equalizing beam limiting device provided in this embodiment also includes two longitudinal connectors 3, which are respectively connected to two adjacent vertical rods 22 located on the same side. With the above arrangement, after the idler roller 23 is adjusted to be close to the bottom of the equalizing beam 10, the two longitudinal connectors 3 are respectively connected to two adjacent vertical rods 22 located on the same side, and the two support leg suspensions 2 are connected to form a stable frame structure, ensuring stability during operation.

[0043] Optionally, the longitudinal link 3 and the vertical rod 22 are connected by bolts, which provides good connection strength and facilitates disassembly.

[0044] Furthermore, in this embodiment, after adjusting the idler roller 23 to be flush with the bottom of the equalizing beam 10, the vertical rod 22 can be connected to the suspension base 1 to improve the connection strength between the outrigger suspension 2 and the suspension base 1. For details, please refer to... Figure 3 The vertical rod 22 has several first connecting holes spaced apart in the vertical direction, and the connecting plate 12 has several second connecting holes spaced apart accordingly. After the roller 23 is adjusted to be close to the bottom of the equalizing beam 10, several pins 4 are used to pass through the first connecting holes and the corresponding second connecting holes and fix them, thereby stabilizing the connection between the vertical rod 22 and the connecting plate 12.

[0045] Please see Figure 5 In this embodiment, a mounting base 5 is connected to the hanging base 1, and a flat rotating screw 6 is connected to the mounting base 5. By screwing the flat rotating screw 6, it is pressed against the side wall of the equalization beam 10 to further strengthen the limiting of the equalization beam 10 and realize the complete limiting of the equalization beam 10 during operation.

[0046] Specifically, the mounting base 5 includes an adjusting plate and two opposing mounting plates. The adjusting plate is vertically arranged along a first direction, and the mounting plates are vertically arranged along a second direction. The two mounting plates are spaced apart along the first direction. The mounting plates are fixed to the hanging base 1. The adjusting plate connects the two mounting plates. A nut is fixed on one side of the adjusting plate. A flat rotating screw 6 is screwed onto the nut and passes through the adjusting plate. The flat rotating screw 6 is tightened so that its end abuts against the side wall of the equalizing beam 10 in the second direction.

[0047] Optionally, the mounting base 5 provided in this embodiment is connected to at least two spaced flat rotating screws 6. Specifically, two nuts are fixed at intervals on one side of the adjusting plate, and the two flat rotating screws 6 are respectively screwed to the two nuts and pass through the adjusting plate. By screwing the two flat rotating screws 6, the other ends of the two flat rotating screws 6 can abut against the side wall of the equalizing beam 10 in the second direction, so as to improve the limiting effect on the equalizing beam 10 and prevent it from swaying left and right.

[0048] Furthermore, the bottom of the beam-changing equipment is hinged to a rotating disk 20 via ball joint bolts. The rotating disk 20 is connected to the equalizing beam 10. In the parked state, after the equalizing beam 10 is positioned, the positions of the equalizing beam 10 and the rotating disk 20 can be adjusted synchronously. It should be noted that the rotating disk 20 is a common structure in the art, and the connection structure between the two will not be described in detail in this embodiment.

[0049] Specifically, please refer to Figure 1 The top of the equalizing beam 10 is provided with two first connecting members 7 spaced apart along the first direction. Each first connecting member 7 has a first mounting hole. Second connecting members 201 are installed on opposite sides of the rotating disk 20. Each second connecting member 201 has a second mounting hole, and the first mounting holes correspond one-to-one with the second mounting holes. The two second connecting members 201 are respectively close to the top of the two first connecting members 7. Bolts are used to pass through the first mounting holes and the corresponding second mounting holes and fix them. By removing the ball joint bolts and pushing the equalizing beam 10 along the first direction, the position of the rotating disk 20 can be adjusted.

[0050] This embodiment provides a balance beam limiting device. In the parked state, the distance between the crossbar 21 and the hanging plate 11 is adjusted by turning the adjusting screw 24, so that the idler roller 23 is close to the bottom of the balance beam 10, initially limiting the balance beam 10. The horizontal rotating screw 6 is further turned to press against the side wall of the balance beam 10 to further strengthen the limiting of the balance beam 10, so as to completely limit the balance beam 10 during operation, prevent the balance beam 10 from shaking, and ensure operational safety.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
