Description

Technical Field

[0001] This utility model relates to the field of bridge erection technology, and in particular to a novel self-balancing bridge erection machine. Background Technology

[0002] In the field of bridge construction, bridge erecting machines are an indispensable key piece of equipment, mainly used to hoist and precisely install precast beam segments onto bridge piers. Traditional bridge erecting machines are usually composed of basic components such as main beam structure, hoisting components, and front and rear outriggers. However, in actual construction processes, especially in areas with poor site conditions and high dust levels, the construction efficiency, equipment lifespan, and operational safety of traditional bridge erecting machines are greatly affected.

[0003] Bridge erecting machines are heavy equipment. The moving friction resistance of their hoisting trolleys on the main beam is enormous, and they are exposed to the outdoors for long periods of time. Manual lubrication is inefficient, wastes a lot of oil, and it is difficult to ensure the uniformity and timeliness of lubrication. This leads to accelerated wear of the tracks and wheel sets, shortened equipment life, insufficient environmental adaptability, and dust permeating the construction site. This dust and debris can easily penetrate into key moving parts such as the main beam tracks, accelerating component wear and corrosion, and even jamming the operating mechanism, affecting the normal function of the equipment. It also increases a lot of cleaning and maintenance costs. Therefore, those skilled in the art have provided a new type of self-balancing bridge erecting machine to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel self-balancing bridge erecting machine. This self-balancing bridge erecting machine achieves automatic lubrication of moving parts through a lubrication assembly, improving operating efficiency and reliability. Meanwhile, the upper and lower air curtain assemblies effectively protect key components and extend equipment life by forming a clean air curtain. These designs together ensure the high performance and low maintenance requirements of the bridge erecting machine in harsh construction environments.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel self-balancing bridge erecting machine, comprising a first main beam and a second main beam, the first main beam and the second main beam being arranged laterally, the upper end face of the first main beam and the second main beam being provided with two hoisting components, the middle of the upper end face of the two hoisting components being provided with a lubrication component, and the lower end face of the first main beam and the second main beam being provided with a front support leg and a rear support leg on the middle sides respectively.

[0006] The two lubrication components include two oil tanks, each oil tank has an oil pump on both sides, and each of the four oil pump output ends has an oil delivery pipe. The four oil pump input ends pass through the two sides of the two oil tanks and lead to the inside of the two oil tanks. The four oil pump output ends pass through the upper end face of the hoisting component and lead to both ends of the lower end face of the hoisting component. Multiple oil leakage holes are linearly arranged in the middle of the upper end face of the first main beam and the second main beam.

[0007] Through the above technical solution, the first and second main beams are stably supported on the piers and leveled. The lubrication components installed above the hoisting components are started simultaneously. Four oil pumps draw lubricating oil from two oil tanks and continuously supply oil to the moving parts of the hoisting components and the linearly arranged oil leakage holes on the main beams through oil pipelines, forming an automatic lubrication system. This reduces the frictional resistance of each moving part during movement, reduces energy consumption and noise, and regular lubrication prevents parts from rusting and wearing, reduces maintenance frequency, ensures smooth movement of the hoisting components to avoid jamming, and improves positioning accuracy.

[0008] Furthermore, the first main beam includes an upper beam, a middle beam at the middle of the lower end face of the upper beam, and a lower beam at the lower end face of the middle beam. Multiple upper air curtain components are linearly arranged on one side of the first main beam. Taking one of the upper air curtain components as an example, the upper air curtain component includes a first air inlet, a first filter screen on the inner wall of the first air inlet, a first support on one side of the first filter screen, a fourth motor on one side of the first support, a first fan at the output end of the fourth motor, and a diffuser on one side of the first fan. The first main beam is located away from... The diffuser vent has an exhaust hole on one side. Multiple lower air curtain components are linearly arranged on both sides of the lower beam. Taking one lower air curtain component as an example, the lower air curtain component includes a second air inlet. The inner wall of the second air inlet is provided with a second filter screen. A second support is provided on one side of the second filter screen. A fifth motor is provided on one side of the second support. A second fan is provided at the output end of the fifth motor. A shrink vent is provided on one side of the second fan. A guide groove is provided on the lower side of the middle beam near the shrink vent. The first main beam and the second main beam are symmetrically arranged.

[0009] To address dust at the construction site, the upper and lower air curtain components located on the side of the main beam operate simultaneously using the above technical solution. The first fan is driven by the fourth motor and the second fan is driven by the fifth motor, respectively. The protective air curtain is formed through the diffuser and converging air vents to keep the outriggers and tracks clean.

[0010] Furthermore, the hoisting assembly includes a hoisting base, and two first motors are provided on both ends of the hoisting base, and first rollers are provided at the output ends of the four first motors;

[0011] With the above technical solution, the hoisting component begins to work. Its four first motors drive the first rollers to move the entire hoisting mechanism longitudinally along the main beam to the designated position. The multiple motors and rollers are evenly distributed, providing stable driving force and reducing the risk of jamming.

[0012] Furthermore, the front outrigger includes an upper tie beam, on which a first hydraulic cylinder and a second hydraulic cylinder are respectively provided on both sides of the upper tie beam. Two second motors are provided on the upper part of each side of the first hydraulic cylinder, and two second rollers are provided on the output ends of the four second motors. Two third motors are provided on the upper part of each side of the second hydraulic cylinder, and three rollers are provided on the output ends of the four third motors. The lower tie beam is provided at the output ends of the first hydraulic cylinder and the second hydraulic cylinder.

[0013] With the above technical solution, when operating on the construction site, the bridge erecting machine first makes precise height adjustment through the first and second hydraulic cylinders of the front and rear outriggers. The first and second hydraulic cylinders are used to achieve stepless adjustment of the outrigger height to adapt to different working conditions and terrains. The rollers driven by the second and third motors enable the outriggers to have walking function, which facilitates the movement of the whole machine.

[0014] Furthermore, the output ends of the four second motors all pass through the outer side of the first hydraulic cylinder and extend to one end face of the second roller, and the output ends of the four third motors all pass through the outer side of the second hydraulic cylinder and extend to one end face of the third roller.

[0015] Through the above technical solution, the output shafts of the second and third motors are directly connected to the external second and third rollers through the sealing structure on the cylinder walls of the first and second hydraulic cylinders, thereby realizing power transmission.

[0016] Furthermore, both the first main beam and the second main beam are provided with front auxiliary support legs at the front of their lower end faces, and both the first main beam and the second main beam are provided with rear auxiliary support legs at the rear of their lower end faces.

[0017] Through the above technical solutions, the front and rear auxiliary outriggers provide additional support points, which greatly enhances the overall stability and safety of the bridge erecting machine during hoisting operations, prevents overturning, and the auxiliary outriggers can effectively share the load of the main outriggers, reducing the bending and vibration of the main beam.

[0018] Furthermore, the rear support leg is configured the same as the front support leg;

[0019] The above technical solutions have achieved standardization and modularization of the front and rear outriggers, simplified design, manufacturing and supply chain management, reduced costs, facilitated the interchangeability and maintenance of parts, and improved equipment availability and maintenance efficiency.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the first main beam and the second main beam are stably supported on the pier and leveled. The lubrication component installed above the hoisting component is started synchronously. Four oil pumps draw lubricating oil from two oil tanks and continuously supply oil to the moving parts of the hoisting component and the linearly arranged oil leakage holes on the main beam through oil pipelines, forming an automatic lubrication system. This reduces the frictional resistance of each moving part during movement, reduces energy consumption and noise, and regular lubrication prevents parts from rusting and wearing, reduces maintenance frequency, ensures smooth movement of the hoisting component to avoid jamming, and improves positioning accuracy.

In this utility model, in order to deal with dust at the construction site, the upper air curtain assembly and the lower air curtain assembly arranged on the side of the main beam operate simultaneously. The first fan is driven by the fourth motor and the second fan is driven by the fifth motor, respectively. The protective air curtain is formed through the diffuser and the converging air vents to keep the legs and tracks clean. Attached Figure Description

[0038] Reference Figure 1-6 This utility model provides an embodiment of a novel self-balancing bridge erecting machine, comprising a first main beam 1 and a second main beam 2, which are arranged laterally.

The input ends of the four oil pumps 402 pass through the two sides of the two oil tanks 401 and lead into the interior of the two oil tanks 401. The output ends of the four oil pumps 402 are respectively... The upper end face of the hoisting assembly 3 is connected to both ends of the lower end face of the hoisting assembly 3.

The first main beam 1 and the second main beam 2 are stably supported on the pier and leveled. The lubrication assembly 4 installed above the hoisting assembly is started synchronously. Four oil pumps 402 draw lubricating oil from two oil tanks 401 and continuously supply oil to the moving parts of the hoisting assembly 3 and the linearly arranged oil leakage holes 404 on the main beam through the oil supply pipe 403, forming an automatic lubrication system. This reduces the frictional resistance of each moving part during movement, reduces energy consumption and noise, prevents parts from rusting and wearing through regular lubrication, reduces maintenance frequency, ensures smooth movement of the hoisting assembly to avoid jamming, and improves positioning accuracy.

The system includes a second air inlet 1007, a second filter 1001 on the inner wall of the second air inlet 1007, a second bracket 1002 on one side of the second filter 1001, a fifth motor 1003 on one side of the second bracket 1002, a second fan 1004 at the output end of the fifth motor 1003, a shrink vent 1005 on one side of the second fan 1004, and a guide groove 1006 on the lower side of the side of the middle beam 102 near the shrink vent 1005. The first main beam 1 and the second main beam 2 are symmetrically arranged. To cope with dust at the construction site, the upper air curtain assembly 9 and the lower air curtain assembly 10 arranged on the side of the main beam operate simultaneously. The first fan 904 is driven by the fourth motor 903 and the second fan 1004 is driven by the fifth motor 1003, respectively.

[0040] like Figure 1 , 3 As shown in Figure 4, the hoisting assembly 3 includes a hoisting base 301. Two first motors 302 are provided on both ends of the hoisting base 301. Each of the four first motors 302 has a first roller 303 at its output end. When the hoisting assembly 3 starts working, its four first motors 302 drive the first rollers 303 respectively to move the entire hoisting mechanism longitudinally along the main beam to the designated position. The multiple motors and rollers are evenly distributed, providing a stable driving force and reducing the risk of jamming.

[0041] like Figure 3As shown, the front outrigger 5 includes an upper tie beam 501. A first hydraulic cylinder 502 and a second hydraulic cylinder 503 are respectively installed on both sides of the upper tie beam 501. Two second motors 504 are installed near the upper part of each side of the first hydraulic cylinder 502. Second rollers 505 are installed at the output ends of the four second motors 504. Two third motors 506 are installed near the upper part of each side of the second hydraulic cylinder 503. Third rollers 507 are installed at the output ends of the four third motors 506. A lower tie beam 508 is installed at the output ends of the first and second hydraulic cylinders 502 and 503. During operation at the construction site, the bridge erecting machine first uses the first hydraulic cylinders 502 and 503 of the front outrigger 5 and the rear outrigger 6 to precisely adjust the height. The first and second hydraulic cylinders 502 and 503 are used to achieve stepless adjustment of the outrigger height, adapting to different working conditions and terrain. The rollers driven by the second motors 504 and 506 enable the outrigger to travel, facilitating the movement of the entire machine.

[0042] like Figure 3 and 4 As shown, the output ends of the four second motors 504 all pass through the outer side of the first hydraulic cylinder 502 and connect to one end face of the second roller 505. The output ends of the four third motors 506 all pass through the outer side of the second hydraulic cylinder 503 and connect to one end face of the third roller 507. The output shafts of the second motors 504 and the third motors 506 are directly connected to the external second rollers 505 and third rollers 507 through the sealing structure on the cylinder walls of the first hydraulic cylinder 502 and the second hydraulic cylinder 503, thereby realizing power transmission.

[0044] like Figure 1 and 2 As shown, the rear outrigger 6 has the same configuration as the front outrigger 5, which realizes the standardization and modularization of the front and rear outriggers, simplifies the design, manufacturing and supply chain management, reduces costs, facilitates the interchangeability and maintenance of parts, and improves the availability and maintenance efficiency of the equipment.

[0045] Working principle: During operation at the construction site, the bridge erecting machine first uses the first hydraulic cylinder 502 and the second hydraulic cylinder 503 of the front support leg 5 and the rear support leg 6 to make precise height adjustment, so that the first main beam 1 and the second main beam 2 are stably supported on the pier and leveled. Then, the hoisting component 3 starts to work. Its four first motors 302 drive the first rollers 303 respectively to move the entire hoisting mechanism longitudinally along the main beam to the designated position. This is a common technology in existing bridge erecting machines and will not be elaborated on here. At the same time, the lubrication component 4 installed above the hoisting component starts synchronously. Four oil pumps 402 draw lubricating oil from two oil tanks 401 and continuously supply oil to the moving parts of the hoisting component 3 and the linearly arranged oil leakage holes 404 on the main beam through the oil supply pipe 403, forming an automatic lubrication system. This reduces the frictional resistance of each moving part during movement, reduces energy consumption and noise, and regular lubrication prevents parts from rusting and wearing, reduces maintenance frequency, ensures smooth movement of the hoisting component to avoid jamming, and improves positioning accuracy.

[0046] To address dust at the construction site, the upper air curtain assembly 9 and the lower air curtain assembly 10, located on the side of the main beam, operate simultaneously. The first fan 904 is driven by the fourth motor 903, and the second fan 1004 is driven by the fifth motor 1003. A protective air curtain is formed through the diffuser vent 905 and the retractor vent 1005 to keep the outriggers and tracks clean. After the current bridge span is erected, the entire machine enters the span-crossing process. The second motor 504 and the third motor 506 on the front outrigger 5 drive the second roller 505 and the third roller 507 respectively to achieve walking motion. This cycle is repeated to complete the erection of the entire bridge.

[0047] The equipment includes a control panel, which enables the equipment to be started and controlled through a human-machine interface and an electrical control system. Input signal processing converts the operator's instructions into electrical signals, and output signal transmission transmits control signals to various actuators to achieve equipment control. This is a commonly used technical solution in existing control systems and will not be elaborated on further here.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
