[0045] Please refer to Figure 1 and Figure 2 In a bridge girder erecting machine automatic transverse movement system in an embodiment, it is used to realize the transverse movement of the bridge girder erecting machine within any bridge width range on the bridge. Generally, the bridge girder erecting machine includes a main girder 10 and legs 20. The legs 20 are installed at the bottom of the main girder 10. The legs 20 generally include a front auxiliary leg 22, a front leg 24, a middle leg 26, and a rear leg 28. The bridge girder erecting machine automatic transverse movement system of the present invention can be installed on the front leg 24 and the middle leg 26. That is to say, a set of bridge girder erecting machine automatic transverse movement system is provided for each of the front leg 24 and the middle leg 26.

[0046] Specifically, the bridge girder erecting machine automatic transverse movement system includes a transverse movement track beam 100, a jacking device 200, an anti-buckling locking device 300, and a transverse movement driving device 400. The transverse movement track beam 100 is arranged on the bridge deck. The function of the jacking device 200 is set for the jacking of the whole bridge girder erecting machine. The jacking device 200 is installed on the legs 20 of the bridge girder erecting machine. The telescoping of the jacking device 200 can jack up or lower the bridge girder erecting machine.

[0047] Please refer to Figure 3 and Figure 4 In an embodiment, two sets of jacking devices 200 are provided. The two sets of jacking devices 200 are respectively arranged at both ends of the cross beam of the legs 20. Each set of jacking devices 200 includes 2 jacking mechanisms 210. That is, each leg 20 is provided with four jacking mechanisms 210, which can ensure the stability of the jacking and lowering process of the bridge girder erecting machine. Of course, in other embodiments, the number of jacking mechanisms 210 on the legs 20 can be specifically set according to needs, such as setting one, two, or three, etc.

[0048] On the basis of the above embodiments, further, the jacking mechanism 210 includes an oil cylinder support 211, a first oil cylinder 212, and a cushion pier 213. The oil cylinder support 211 is installed on the legs 20. Specifically, the oil cylinder support 211 can be fixed to the side of the legs 20 by bolts. The first oil cylinder 212 is installed on the oil cylinder support 211. The cushion pier 213 is connected to the first oil cylinder 212. The cushion pier 213 can support on the bridge deck, and thus the jacking mechanism 210 can jack up the bridge girder erecting machine.

[0049] Among them, by the telescoping of the first oil cylinder 212, the bridge girder erecting machine can be jacked up or lowered. The cushion pier 213 should support on the support surface of the bridge deck to ensure the safety of the jacking process. The support surface refers to the bridge deck or the sleepers or piers on the bridge deck, etc.

[0050] On the basis of the above embodiments, further, a first upper limit member 214 and a first lower limit member 215 are provided at intervals on the first oil cylinder 212. The first upper limit member 214 is located above the first lower limit member 215. The first upper limit member 214 and the first lower limit member 215 cooperate to define the stroke of the first oil cylinder 212 and control the position of the jacking and lowering of the bridge erector. In one embodiment, the first oil cylinder 212 is provided with a first probe rod 216. When the first probe rod 216 contacts the first upper limit member 214 or the first lower limit member 215, the first oil cylinder 212 is controlled to stop moving.

[0051] The function of the reverse buckling and locking device 300 is to jack up the transverse movement track beam 100, so that the transverse movement driving device 400 presses against the transverse movement track beam 100, providing sufficient friction for the transverse movement driving device 400 to drive the transverse movement track beam 100 to move transversely. The reverse buckling and locking device 300 is installed on the support leg 20, and the reverse buckling and locking device 300 is connected to the transverse movement track beam 100. The expansion and contraction of the reverse buckling and locking device 300 is used to lift or lower the transverse movement track beam 100.

[0052] In one embodiment, the reverse buckling and locking device 300 includes a second oil cylinder 310 and a fixing plate 320. The second oil cylinder 310 is installed on the support leg 20, the fixing plate 320 is connected to the second oil cylinder 310, and the fixing plate 320 is arranged at the bottom of the transverse movement track beam 100. Among them, the expansion and contraction of the second oil cylinder 310 can drive the fixing plate 320 to rise or fall, and then drive the transverse movement track beam 100 thereon to rise and fall.

[0053] On the basis of the above embodiments, further, the number of the second oil cylinders 310 is two. The two second oil cylinders 310 are respectively located on both sides of the transverse movement track beam 100, and the two second oil cylinders 310 are respectively connected to both ends of the fixing plate 320 to realize that the fixing plate 320 holds the transverse movement track beam 100 and ensure the stability of the transverse movement track beam 100 during the lifting and lowering process.

[0054] On the basis of the above embodiments, the reverse buckling and locking device 300 further includes rubber wheels 330. The rubber wheels 330 are rotatably arranged on the fixing plate 320, and the rubber wheels 330 are in contact with the transverse movement track beam 100. The fixing plate 320 bears the transverse movement track beam 100 through the rubber wheels 330. The rubber wheels 330 are relatively soft, which can effectively protect the transverse movement track beam 100, and at the same time facilitate the transverse movement of the transverse movement track beam 100 and reduce the friction during the transverse movement of the transverse movement track beam 100.

[0055] The transverse movement driving device 400 is installed on the support leg 20, and the transverse movement driving device 400 is the walking structure of the bridge erector itself. The transverse movement driving device 400 can be in contact and cooperation with the transverse movement track beam 100 to drive the transverse movement track beam 100 and the bridge erector to move transversely.

[0056] Specifically, when the transverse movement track beam 100 is suspended by the bridge erecting machine, the transverse movement driving device 400 contacts the transverse movement track beam 100. Under the action of friction, the transverse movement driving device 400 drives the transverse movement track beam 100 to move transversely. When the transverse movement track beam 100 is placed on the bridge deck and the whole weight of the bridge erecting machine is borne by the transverse movement track beam 100, the transverse movement driving device 400 contacts the transverse movement track beam 100. Under the action of friction, the transverse movement driving device 400 realizes the transverse movement of the bridge erecting machine on the transverse movement track.

[0057] In an embodiment, the transverse movement driving device 400 includes a motor 410, a gearbox 420 and a wheel 430. The motor 410 and the gearbox 420 are installed on the support leg 20. Specifically, both the motor 410 and the gearbox 420 are installed on the cross beam of the support leg 20. The output shaft of the motor 410 is connected to the input shaft of the gearbox 420, and the wheel 430 is installed on the output shaft of the gearbox 420. The wheel 430 can contact and friction with the transverse movement track beam 100.

[0058] Wherein, the motor 410 can drive the gearbox 420 to operate, and further drive the wheel 430 to rotate. The wheel 430 contacts the transverse movement track beam 100, and the rotation of the wheel 430 can drive the transverse movement track beam 100 to move transversely, or drive the bridge erecting machine to move transversely along the transverse movement track beam 100.

[0059] Please refer to Figure 5 In an embodiment, a second lower limit member 340 is provided on the second oil cylinder 310. The second oil cylinder 310 realizes the telescopic movement through a hydraulic system. A pressure relay is provided in the hydraulic system. The second lower limit member 340 and the pressure relay cooperate to limit the stroke of the second oil cylinder 310. In an embodiment, both the first oil cylinder 212 and the second oil cylinder 310 are controlled to expand and contract through the hydraulic system. The first oil cylinder 212 and the second oil cylinder 310 are arranged in parallel in the oil circuit. Both the first oil cylinder 212 and the second oil cylinder 310 realize the transformation of the telescopic movement through a directional control valve. And both the first oil cylinder 212 and the second oil cylinder 310 are connected with a balance valve to keep a certain pressure of the hydraulic oil in the oil cylinder. The pressure relay is communicated with the rod chamber of the second oil cylinder 310.

[0060] Specifically, a second probe rod 350 is provided on the second oil cylinder 310. When the second probe rod 350 contacts the second lower limit member 340, the second oil cylinder 310 stops moving. At this time, the second oil cylinder 310 is in the maximum extended state. When the second oil cylinder 310 starts to contract, after the wheel 430 of the transverse movement driving device 400 contacts the transverse movement track beam 100, the second oil cylinder 310 continues to contract. The pressure of the hydraulic oil rises to the set value of the pressure relay, and the pressure relay is energized to control the second oil cylinder 310 to stop retracting, providing sufficient friction for the transverse movement driving device 400 to drive the transverse movement track beam 100 to move transversely.

[0061] In one embodiment, left and right limit members 110 and 120 are respectively provided at both ends of the transverse movement track beam 100. The left and right limit members 110 and 120 cooperate to limit the transverse movement of the transverse movement track beam 100 and the bridge erecting machine. Specifically, when the transverse movement track beam 100 is transversely moved, when the left limit member 110 contacts the support leg 20, it indicates that the transverse movement of the transverse movement track beam 100 is in place, and the transverse movement of the transverse movement track beam 100 is stopped. When the bridge erecting machine is transversely moved, when the support leg 20 of the bridge erecting machine contacts the right limit member 120, it indicates that the transverse movement of the bridge erecting machine is in place, and the transverse movement of the entire bridge erecting machine is stopped.

[0062] Please refer to Figure 6 , on the other hand, the present invention also provides a method for transverse movement of a bridge erecting machine. To implement this transverse movement method, the above-mentioned automatic transverse movement system of the bridge erecting machine is specifically adopted. Specifically, the transverse movement method includes the following steps:

[0063] Step S110: The lifting device 200 is supported on the bridge deck, the lifting device 200 extends to lift the bridge erecting machine, and after the bridge erecting machine is suspended, the transverse movement driving device 400 is separated from the transverse movement track beam 100.

[0064] Please refer to Figure 7 , specifically, when the bridge erecting machine needs to be transversely moved, the first oil cylinder 212 extends, so that the cushion pier 213 supports the supporting surface of the bridge deck, and the supporting surface refers to the bridge deck or the sleepers or piers on the bridge deck, etc. The first oil cylinder 212 continues to extend, the entire bridge erecting machine rises, the wheels 430 of the transverse movement driving device 400 are separated from the transverse movement track beam 100, and the whole machine is suspended. At this time, the first upper limit member 214 of the first oil cylinder 212 is triggered, and the first oil cylinder 212 stops extending.

[0065] Step S120: The reverse buckling and locking device 300 contracts, lifting the transverse movement track beam 100 upward until the transverse movement track beam 100 contacts the transverse movement driving device 400.

[0066] Please refer to Figure 8 , specifically, the second oil cylinder 310 is activated to contract, and the transverse movement track beam 100 rises accordingly under the action of the fixed plate 320 until the transverse movement track beam 100 is in close contact with the wheels 430 of the transverse movement driving device 400. After reaching sufficient pressure, at this time, the pressure relay is triggered, the second oil cylinder 310 stops working and maintains pressure through the balance valve to keep the hydraulic oil at a certain contraction pressure.

[0067] Step S130: The transverse movement driving device 400 drives the transverse movement track beam 100 to move transversely under the action of friction.

[0068] Please refer to Figure 9, specifically, the motor 410 of the transverse movement driving device 400 starts, driving the wheel 430 to rotate. Under the action of friction, the wheel 430 drives the transverse movement track beam 100 to move horizontally to the right until the left limit member 110 on the transverse movement track beam 100 contacts the support leg 20, the left limit member 110 is triggered, and the motor 410 of the transverse movement driving device 400 stops working.

[0069] Step S140: The reverse buckling and locking device 300 extends and lowers the transverse movement track beam 100 to disengage the transverse movement track beam 100 from the transverse movement driving device 400.

[0070] Please refer to Figure 10 , specifically, the second oil cylinder 310 starts to extend, and the transverse movement track beam 100 disengages from the wheel 430 of the transverse movement driving device 400. The second oil cylinder 310 continues to extend. At this time, the second lower limit member 340 on the second oil cylinder 310 is triggered, and the second oil cylinder 310 stops extending.

[0071] Step S150: The jacking device 200 contracts and lowers the bridge erecting machine so that the transverse movement track beam 100 supports on the bridge deck. Then the jacking device 200 continues to contract to make the transverse movement driving device 400 contact the transverse movement track beam 100.

[0072] Please refer to Figure 11 , specifically, the first oil cylinder 212 starts to contract, and the overall height of the bridge erecting machine decreases until the transverse movement track beam 100 supports on the bridge deck support surface. The first oil cylinder 212 continues to contract, and the wheel 430 of the transverse movement driving device 400 completely contacts the transverse movement track beam 100, and the cushion pier 213 becomes void. The overall weight of the bridge erecting machine is all pressed on the transverse movement track beam 100. At this time, the first lower limit member 215 of the first oil cylinder 212 is triggered, and the first oil cylinder 212 stops contracting.

[0073] Step S160: The transverse movement driving device 400 drives the bridge erecting machine to move horizontally under the action of friction.

[0074] Please refer to Figure 12 , specifically, the motor 410 of the transverse movement driving device 400 starts, driving the wheel 430 to rotate. Under the action of friction, the wheel 430 drives the bridge erecting machine to move to the right on the transverse movement track beam 100. Until the right limit member 120 contacts the support leg 20, the right limit member 120 is triggered, and the motor 410 stops working. The bridge erecting machine is located at the rightmost end of the transverse movement track beam 100.

[0075] If the bridge erecting machine has not moved to the predetermined position, repeat the above steps S110 - S160 until the whole bridge erecting machine is horizontally moved to any required position.

[0076] The above bridge erecting machine automatic transverse translation system and transverse translation method transfer the total weight of the bridge erecting machine from the transverse translation track beam 100 to the bridge structure through the jacking device 200 on the outrigger 20. The function of the reverse buckling and locking device 300 is to lift and lock the transverse translation track beam 100, so that the state of the transverse translation track beam 100 is changed from being supported on the bridge structure to being suspended on the outrigger 20 of the bridge erecting machine. The transverse translation drive mechanism drives the transverse translation track beam 100 to move laterally. After the transverse translation track beam 100 is in place, the bridge erecting machine is placed on the transverse translation track beam 100, and the whole machine is laterally translated through its own power. That is, the transverse translation track beam 100 is first translated a certain distance, and then the whole machine is translated a certain distance, and so on in a cycle to achieve lateral translation within any bridge width range. The system has a simple structure and a small amount of modification to the existing equipment; the transverse translation track beam 100 is short in length, and the transverse translation drive mechanism of the bridge erecting machine is used as the power to drive the transverse translation track beam 100, which is economical. The whole transverse translation process is completed automatically without manual assistance, with high efficiency and low operation intensity.

[0077] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
