Description

Technical Field

[0001] This utility model relates to the field of bridge erecting machine technology, and in particular to a single main beam transport and erection integrated machine with a lifting device. Background Technology

[0002] The single main beam transport and erection integrated machine mainly works on bridges and is used for transporting beams during the bridge erection process. It is mainly used for the lifting, transporting, and erection of whole-span box girders on high-speed railways and passenger dedicated lines. Compared with the existing double main beam bridge erection machine, the integrated machine does not require auxiliary equipment other than the main machine to cooperate in the beam erection. Its structure is simple and the operation procedure is simple, which can meet the requirements of beam erection at tunnel entrances and inside tunnels.

[0003] Currently, during the bridge-mounting phase of a single main beam transport and erection machine, a temporary access road is typically constructed for the machine to access the bridge. This access road must be designed to meet both the environmental elevation and the slope requirements of the equipment. If the elevation difference is too large, the length of the access road needs to be increased to meet the equipment's usage requirements, directly leading to increased costs and wasting time and effort. The increased access road length also affects the beam transport efficiency of the equipment, extending the construction period. Furthermore, in harsh construction environments and conditions, the cost of constructing the access road will increase further.

[0004] Patent CN111535194A discloses a "dedicated hoisting system for a 900-ton integrated bridge lifting machine," which can directly hoist the machine onto a bridge. However, this device has the following problems during use: 1. The hydraulic cylinder lateral adjustment of the lifting point sliding beam is not very useful, because the lifting trolley of the cross-line hoist can move and align itself; 2. The sliding beam of the bridge lifting machine is fixed on the lifting device of the cross-line hoist, and the concave lateral sliding slider that cooperates with it is installed on the top surface of the main beam of the integrated machine. 1. The location and structural design make it inconvenient for operators to install and dismantle the boom assembly (in contrast, the boom assembly of the lifting device in this solution is easy to install and dismantle); 2. Before the integrated machine completes the lifting and starts the beam transport operation, the lifting device needs to be partially disassembled (because it restricts the back-and-forth swing of the back carriage) to avoid the lifting device assembly from twisting, deforming, or thread jamming due to the slope of the track when the integrated machine is traveling (in contrast, the two lifting devices in this solution do not need to be disassembled during the entire operation cycle of the integrated machine after the initial installation). Utility Model Content

[0005] The purpose of this utility model is to provide a single main beam transport and erection integrated machine with a lifting device, which eliminates the need to build access roads and enables the entire machine to be lifted onto the bridge, making the beam erection process more efficient, saving costs and shortening the construction period.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A single main beam transport and erection integrated machine with a lifting device is provided. The integrated machine is equipped with a trolley to control its movement. The integrated machine is equipped with a first lifting device and a second lifting device. The first lifting device includes a first crossbeam connected to the integrated machine. The two sides of the first crossbeam are provided with brackets for passing through lifting tools.

[0008] Preferably, the first crossbeam includes a crossbeam cover plate and two crossbeam webs, and the two ends of the first crossbeam are provided with first connecting holes for connecting brackets.

[0009] Preferably, the cow leg includes an upper cover plate, a lower cover plate, and a belly plate. A second connecting hole for connecting to the first crossbeam is provided on one side of the cow leg, and a third connecting hole for inserting a lifting device is provided on the other side of the cow leg.

[0010] Preferably, the second lifting device includes a hinge seat connected to the integrated machine and a second crossbeam for threading the lifting device through, the second crossbeam being connected to the hinge seat via a tie rod.

[0011] Preferably, the second crossbeam includes two main crossbeam bodies and a cross brace connecting the two main crossbeam bodies.

[0012] Preferably, the main body of the crossbeam is provided with fourth connecting holes for connecting tie rods on both sides, and the main body of the crossbeam is provided with a fifth connecting hole for connecting lifting devices in the middle.

[0013] Preferably, the hinge seat is provided with a sixth connecting hole for connecting the tie rod and a seventh connecting hole for connecting the integrated machine.

[0014] Preferably, the connecting beam between the integrated machine and the hinge seat is provided with multiple eighth connecting holes that mate with the seventh connecting hole.

[0015] Preferably, a crossbeam reinforcement plate for the integrated machine is provided at the connection crossbeam between the integrated machine and the hinge seat.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model has two lifting devices on the integrated machine, which can directly lift the integrated machine onto the bridge, greatly reducing the amount of preliminary work and shortening the bridge construction period.

[0018] 2. Both the first and second crossbeams of this utility model are provided with connection holes for lifting tools, so that existing conventional lifting tools can be used directly for lifting without the need for special processing of special lifting tools or secondary lifting tools.

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1 and Figure 2As shown, a single main beam erection machine with a lifting device is disclosed. The machine 100 is equipped with a trolley 200 for controlling its movement. The trolley 200 is divided into a front trolley and a rear trolley. The machine 100 is equipped with a first lifting device 300 and a second lifting device 400. The first lifting device 300 includes a first crossbeam 1 connected to the machine 100. Brackets 2 for mounting lifting devices are provided on both sides of the first crossbeam 1. A first pin 3 passes between the first crossbeam 1 and the brackets 2. In this embodiment, the first lifting device 300 is the front lifting point, located on the 7th section of the main beam of the machine 100; the second lifting device 400 is the rear lifting point, located at the rear trolley of the machine 100.

[0034] like Figure 4 As shown, the first crossbeam 1 is rectangular in shape, including two crossbeam cover plates 11 and two crossbeam webs 12. First connecting holes are provided at both ends of the first crossbeam 1 for inserting first pins 3 to connect to the brackets 2. A crossbeam reinforcing ring 14 is also provided at the first connecting hole, and a crossbeam partition 13 is provided between the two crossbeam webs 12. Mounting holes are provided in the web of the main beam of the integrated machine 100. The first crossbeam 1 passes through the mounting holes in the web of the main beam and is welded to the main beam as a single unit, making the hoisting structure more stable and reliable.

[0035] like Figure 5 and Figure 6 As shown, the bracket 2 includes an upper bracket cover plate 21, a lower bracket cover plate 24, and a bracket web plate 23. One side of the bracket 2 has a second connecting hole for threading a first pin 3 to connect to the first crossbeam 1. Two first pins 3 can be arranged vertically on a single bracket 2, ensuring clear force distribution and simple, convenient operation. The other side of the bracket 2 has a third connecting hole for threading a lifting device. The third connecting hole is elongated, accommodating various lifting hole spacings for cross-line lifting devices, making operation simple and convenient. A first reinforcing plate 22 is installed at the second connecting hole, and a second reinforcing plate 25 is installed at the third connecting hole. A first bracket partition 26 and a second bracket partition 27 are also installed inside the bracket 2.

[0036] like Figure 3 and Figure 7 As shown, the second lifting device 400 includes a hinge 8 connected to the integrated machine 100 and a second crossbeam 4 for passing through the lifting device. The second crossbeam 4 is connected to the hinge 8 by a tie rod 6.

[0037] like Figure 8 As shown, the second crossbeam 4 includes two main crossbeam bodies 41 and a cross brace 42 connecting the two main crossbeam bodies 41. The main crossbeam bodies 41 are connected together by the cross brace 42, providing sufficient rigidity to prevent them from being out of plane or twisting during lifting.

[0038] The main body of the crossbeam 41 has fourth connecting holes 43 on both sides for connecting the second pin 5 to the tie rod 6, and a fifth connecting hole 44 for connecting the lifting device is provided in the middle of the main body of the crossbeam 41.

[0039] like Figure 9 As shown, the hinge seat 8 is provided with a sixth connecting hole 81 through which the third pin 7 passes to connect the pull rod 6 and a seventh connecting hole 82 to connect the integrated machine 100.

[0040] The connecting beam (i.e., the back carriage beam) between the integrated machine 100 and the hinge seat 8 is equipped with multiple eighth connecting holes that mate with the seventh connecting hole 82, which can accommodate various lifting hole spacings of the cross-line lifting device. Among them, the seventh connecting hole 82 and the eighth connecting hole are both smooth holes.

[0041] A crossbeam reinforcement plate 9 is provided at the connection beam between the integrated machine 100 and the hinge seat 8.

[0042] like Figure 10 As shown, a ninth connecting hole is provided at both ends of the pull rod to cooperate with the second pin 5 and the third pin 7, respectively.

[0043] This invention utilizes two lifting devices to lift the entire machine onto the bridge via a cross-line, eliminating the need for temporary access roads. This method is convenient, fast, and saves time transporting beams via temporary access roads. Furthermore, the lifting point structure is simple, utilizing the existing lifting equipment for precast beams from the beam yard for lifting onto the bridge without any modifications. The installation and removal of the lifting equipment are consistent with conventional beam lifting operations. The installation of the second lifting device 400 does not affect the bridge erection machine's conventional beam erection operations.
