Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, specifically to a railway double-guide beam bridge erecting machine carrying device. Background Technology

[0002] The traditional method for relocating railway double-girder bridge erecting machines is to disassemble the machine, transport it to a new construction site, and then reassemble it. Because each disassembly and reassembly takes a long time, the bridge erection schedule cannot be guaranteed. Furthermore, after each assembly, certification is required before the machine can be put into use. In typical railway projects, the erection of T-beams often requires the bridge erecting machine to be relocated as many as ten times, each time disassembled, relocated, and reassembled, which significantly impacts project costs and schedule. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a transport device for a railway double-girder bridge erecting machine, which can be used to transport the bridge erecting machine.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a railway double-guide beam bridge erecting machine carrying device, comprising a main crossbeam, a supporting part, and protective legs;

[0005] The main crossbeam is detachably mounted on the beam-carrying artillery vehicle;

[0006] The supporting part includes a pier, an anchor beam, and a threaded steel bar. The pier is fixedly installed on the main crossbeam, and the anchor beam is installed above the pier and connected to the pier through the threaded steel bar.

[0007] Both ends of the main crossbeam are equipped with detachable protective legs, which are retractable.

[0008] First, the device is hoisted onto the beam-transporting vehicle, and the main crossbeam is installed on the vehicle. Then, the bridge erecting machine is raised to a certain height, and the beam-transporting vehicle moves beneath it, extending its protective outriggers and supporting them on the ground. The bridge erecting machine is then slowly lowered onto the device. Once the main beam of the bridge erecting machine rests on the pier, anchor beams are installed using threaded steel bars, locking the main beam of the bridge erecting machine securely to the pier. The machine is then ready for transport to the site.

[0009] The beneficial effects of the above-mentioned railway double-girder bridge erecting machine carrying device are: it can use the beam transport cannon to carry the entire bridge erecting machine to the site, simplifying the process of bridge erecting machine transfer and greatly shortening the transfer time.

[0010] Furthermore, the main crossbeam is assembled from I-shaped steel beams.

[0011] Based on the total weight of the bridge erecting machine, appropriate I-beams can be selected to assemble the main crossbeams to ensure that the strength requirements are met.

[0012] Furthermore, the bottom of the main crossbeam is provided with multiple sockets along the axial direction, which can be inserted and matched with the pins of the beam transport vehicle.

[0013] When the device is hoisted onto the beam transport vehicle, it can be quickly positioned and installed through the insertion and connection of the pin shaft and the socket interface.

[0014] Furthermore, the socket interface is provided in three parts, one of which is located in the middle of the ground of the main crossbeam, and the other two are symmetrically located on both sides.

[0015] Depending on road conditions and transport distance, a method of one main vehicle and two auxiliary vehicles can be chosen for relocation. The main vehicle connects to the socket joint in the middle of the main crossbeam, and the two auxiliary vehicles travel side by side, sharing a single carrying device, and connecting to the socket joints on both sides of the main crossbeam respectively. Alternatively, a method of one main vehicle and one auxiliary vehicle can be chosen for relocation, with both the main vehicle and auxiliary vehicle connected to the socket joint in the middle of the main crossbeam.

[0016] Furthermore, the socket is made of steel pipe.

[0017] Use steel pipes of sufficient strength to ensure that the device can be stably installed on the beam transport vehicle.

[0018] Furthermore, the bottom of the main crossbeam is provided with an anti-detachment groove, and the beam transport vehicle is provided with a crossbeam;

[0019] The anti-detachment groove is an arc-shaped sliding groove, and two are provided symmetrically, both of which are concentric with the socket and the pin. The two ends of the crossbeam are provided with sliders that are slidably connected to the anti-detachment groove.

[0020] When the beam transport vehicle experiences bumps on the road, the crossbeam and anti-detachment groove can prevent the main crossbeam from falling off the beam transport vehicle, and the arc-shaped sliding groove and slider can ensure that the main crossbeam and the beam transport vehicle have a certain amount of rotation space.

[0021] Furthermore, the pier pad is welded to the main crossbeam.

[0022] The pier pad and the main crossbeam are fixedly connected by welding, which provides good stability.

[0023] Furthermore, a reinforcing plate is provided between the pier and the main crossbeam.

[0024] Adding reinforcing plates can further enhance strength.

[0025] Furthermore, the protective outrigger includes a threaded sleeve and a screw. The threaded sleeve is detachably mounted at both ends of the main crossbeam. One end of the screw is connected to the threaded sleeve, and the other end is provided with a support plate that can abut against the ground.

[0026] By installing the threaded sleeve onto the main crossbeam and rotating the screw to move it relative to the main crossbeam, the protective outriggers can be extended and placed on the ground. Furthermore, the support plate has a larger surface area, improving stability.

[0027] Furthermore, the threaded sleeve is connected to the main crossbeam by bolts.

[0028] The threaded sleeve and main beam are connected by bolts, which facilitates easy loading and unloading. Attached Figure Description

[0037] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0038] Please see Figures 1 to 5 This utility model provides a railway double-guide beam bridge erecting machine carrying device, including a main crossbeam, a support part and protective legs.

[0039] Specifically, the main crossbeam 10 can be detachably installed on the beam transport vehicle 1. The supporting part includes a pier 21, an anchor beam 22, and a threaded steel bar 23. The pier 21 is fixedly installed on the main crossbeam 10, and the anchor beam 22 is located above the pier 21 and connected to the pier 21 by the threaded steel bar 23. Both ends of the main crossbeam 10 are provided with detachable protective legs 30, which are telescopic.

[0040] First, the device is hoisted onto the beam-carrying gun vehicle, and the main crossbeam 10 is installed on the beam-carrying gun vehicle 1. Then, the bridge erecting machine is raised to a certain height, the beam-carrying gun vehicle is driven under the bridge erecting machine, and the protective outriggers 30 are extended and supported on the ground. The bridge erecting machine can then be slowly lowered onto the device. The main beam of the bridge erecting machine rests on the pier pad 21, and the anchor beam 22 is installed through the threaded steel 23, so that the anchor beam 22 and the pier pad 21 lock the main beam of the bridge erecting machine. The protective outriggers 30 can then be retracted. The bridge erecting machine is then transferred by the beam-carrying gun vehicle and the carrying device, which simplifies the process of relocating the bridge erecting machine and greatly shortens the relocation time.

[0041] Specifically, the main crossbeam is assembled from I-beams. Based on the total weight of the bridge erecting machine, suitable I-beams can be selected to assemble the main crossbeams to ensure that the strength requirements are met.

[0042] The bottom of the main crossbeam 10 is provided with multiple socket joints 11 along the axial direction, which can be inserted and matched with the pins of the beam transport vehicle. When the device is hoisted onto the beam transport vehicle, the positioning and installation can be completed quickly through the insertion and matching of the pins and socket joints 11. The socket joints are made of steel pipes with sufficient strength to ensure that the device can be stably installed on the beam transport vehicle.

[0043] In this embodiment, there are three socket interfaces 11, one of which is located in the middle of the bottom surface of the main crossbeam 10, and the other two are symmetrically located on both sides. Different combinations of transport methods can be selected depending on road conditions and transport distance. When the bridge erecting machine needs to be moved over long distances and road conditions permit, one main vehicle and two auxiliary vehicles can be selected. The main vehicle connects to the socket interface 11 in the middle of the main crossbeam 10 (e.g., Figure 2 The beam transport vehicle shown is a single-vehicle carrier, with two auxiliary vehicles traveling side-by-side sharing a single transport device (e.g., Figure 3 The bridge erecting machine is shown as a dual-vehicle transporter (1 carrying the beam), with each vehicle connected to the socket joints 11 on both sides of the main crossbeam 10. The main vehicle and the auxiliary vehicle support the front and rear ends of the bridge erecting machine, providing three-point support and increasing stability and safety during transport. When the bridge erecting machine needs to be moved short distances or when road conditions are poor, one main vehicle and one auxiliary vehicle can be used, with both vehicles carrying the beam and connecting to the socket joint 11 in the middle of the main crossbeam 10.

[0044] Specifically, such as Figure 5 As shown, the bottom of the main crossbeam 10 is provided with a fixedly welded anti-detachment groove 24, and the beam transport vehicle 1 is provided with a fixedly welded crossbeam 2. The anti-detachment groove 24 is an arc-shaped sliding groove, and two are symmetrically provided, both concentric with the socket and the pin. Both ends of the crossbeam 2 are provided with sliders that are slidably connected to the anti-detachment groove. When the beam transport vehicle experiences bumps on the road, the crossbeam 2 and the anti-detachment groove 24 can prevent the main crossbeam from falling off the beam transport vehicle. Compared with a single socket and pin, it has a better anti-detachment effect, and the arc-shaped sliding groove and the slider can ensure that the main crossbeam and the beam transport vehicle have a certain amount of rotation space when bumping.

[0045] Specifically, the pier pads are fixed to the main crossbeam by welding, which provides good stability. Reinforcing plates can also be added to further enhance the strength.

[0046] Specifically, the protective outriggers 30 include threaded sleeves 31 and screws 32. The threaded sleeves 31 are detachably mounted at both ends of the main crossbeam 10, and the screws 32 are threadedly connected to the threaded sleeves 31, with a support plate 33 at the bottom. By installing the threaded sleeves 31 on the main crossbeam 10 and rotating the screws 32 to move them relative to the main crossbeam 10, the support plate 33 can be supported on the ground to withstand the impact of placing the bridge erecting machine. The protective outriggers 30 can be pre-installed during transport to shorten preparation time before relocation. After the bridge erecting machine is placed on the device, the protective outriggers 30 are retracted, and the artillery vehicle supports the bridge erecting machine. Furthermore, the protective outriggers 30 increase safety during relocation.

[0047] In this embodiment, the threaded sleeve 31 is connected to the main crossbeam 10 by bolts. The bolted connection between the threaded sleeve 31 and the main crossbeam 10 facilitates easy assembly and disassembly.

[0048] The working principle of the above-mentioned railway double-girder bridge erecting machine transport device is as follows: First, the device is pre-assembled according to the relocation requirements of the bridge erecting machine and hoisted onto the beam transport vehicle. The socket 11 is straightly inserted into the pin shaft of the vehicle. The bridge erecting machine is parked in an open area beforehand, and the auxiliary outriggers are used to lift the bridge erecting machine to a certain height. Then, the vehicle is driven to the bottom of the bridge erecting machine, and the hydraulic cylinders of the auxiliary outriggers of the bridge erecting machine are slowly lowered, allowing the main beam of the bridge erecting machine to land on the pier pad 21. Then, the anchor beam 22 is installed, and the anchor beam 22 and the pier pad 21 are locked together by the threaded steel bar 23. After checking that the device is stable under force, it can be transported to the relocation site.

[0049] Using the aforementioned railway double-girder bridge erecting machine transport device, the entire bridge erecting machine is transported to the site using a beam transport vehicle. This simplifies the cumbersome disassembly and assembly processes during the relocation of the bridge erecting machine, enabling the complete machine to be transported and significantly shortening the relocation time. Furthermore, it can meet the requirements for rapid and safe relocation under different distances and road conditions, effectively improving construction efficiency and reducing construction costs.
