Description

Technical Field

[0001] This utility model relates to the field of railway hoisting construction technology, and in particular to a hoisting structure for coordinated operation of a beam lifting machine. Background Technology

[0002] With the rapid development of high-speed railways, more and more problems are arising under various special working conditions. In some construction sites, there are situations where there are too many continuous beams to complete, affecting subsequent bridge erection and track laying. To ensure the construction period, existing methods mostly involve using a beam lifting machine to hoist the beams onto the bridge. However, since the subsequent flange plate construction needs to closely follow the bridge erection, concrete cannot be transported to the site. Therefore, concrete trucks and other construction equipment need to be hoisted onto the bridge. Because concrete trucks are heavy, with a full load of approximately 11 cubic meters of concrete and a total weight of approximately 50 tons, a single beam lifting machine cannot bear the load. Furthermore, different equipment has significant differences in size and weight; for example, the weight of a fully loaded and empty concrete truck differs considerably. The lifting structure needs to be able to adjust the lifting point. Extensive research has failed to find a method for hoisting large concrete trucks, so a hoisting platform and lifting tools for the beam lifting machine and platform have been specially designed. Therefore, a hoisting structure that allows multiple beam lifting machines to work together is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a lifting structure for the coordinated operation of beam lifting machines, which can realize the coordinated lifting of multiple beam lifting machines, and at the same time adjust the lifting position according to the object being lifted.

[0004] The purpose of this utility model is achieved through the following technical solution: a lifting structure for coordinated operation of beam lifting machines, comprising multiple adjusting beams and multiple coordinated beam lifting machines. Each adjusting beam corresponds one-to-one with a beam lifting machine. Each beam lifting machine is equipped with a front lifting beam trolley and a rear lifting beam trolley. Each adjusting beam is simultaneously connected to the front and rear lifting beam trolleys on its corresponding beam lifting machine. Each adjusting beam is equipped with lifting devices located on both sides of the object to be lifted. Each adjusting beam also has multiple adjustment holes for adjusting the distance between the lifting devices on both sides. The adjusting beam divides the area where the object to be lifted is located into multiple lifting zones, and the object to be lifted has a lifting point in each lifting zone. Each lifting device consists of a mounting part and lifting lugs located on both sides of the mounting part. The mounting part has mounting holes, which are mounted on the adjustment holes via rotating shafts. The lifting lugs are connected to the lifting points on the object in the lifting zone via steel cables. The lifting lugs on both sides of the mounting part are respectively connected to the lifting points in different lifting zones.

[0005] Both the front and rear lifting beam trolleys are equipped with winch units and movable pulleys driven by the winch units. A connecting arm is provided between the adjusting beam and each movable pulley. One end of the connecting arm is detachably mounted on the shell wall of the pulley assembly, and the other end is hinged to the upper end of the adjusting beam. There are at least two connecting arms.

[0006] Preferably, the adjustment holes on both sides of the adjustment beam are symmetrically arranged, and the adjustment holes on the same side of the adjustment beam are evenly arranged. The arrangement of the adjustment holes facilitates synchronous adjustment according to the lifted object when the beam lifting machine is working in coordination, which is convenient for lifting.

[0007] As a further improvement, the mounting section is also provided with a slot, which forms a lifting ring structure on the lifting device. During lifting, a steel cable is fitted into the slot and engages with the lifting point on the object in the lifting area. The slot is arranged on the surface of the mounting section along the lifting direction. The lifting lug on the lifting device is the main lifting point, and the lifting ring structure is the auxiliary lifting point. During lifting, the main lifting point performs normal operation, while the auxiliary lifting point assists in lifting according to the condition of the object. It can be directly engaged with the object or engaged with the lifting device on the same adjusting beam for auxiliary positioning and guidance during the lifting process (in which case the steel cable can pass through the object, which is beneficial for positioning and guidance judgment). The auxiliary lifting role is very significant in the coordinated operation of wheeled beam lifting machines, and it can also be used for auxiliary positioning in rail-mounted beam lifting machines.

[0008] In actual production, many items need to be lifted by the beam lifting machine during bridge erection. The lifting can be done directly on the lifting platform (on which the object is placed) or directly on the object itself. Lifting points can be set on both the platform and the object. Details will not be elaborated here. Depending on the size and weight of the object, it is moved to the lifting area or platform. Simultaneously, multiple beam lifting machines working in coordination move to their designated positions. Adjusting beams and lifting lugs are installed on the beam lifting machines. For objects of different sizes, the distance between the lifting lugs on both sides is adjusted using the adjustment holes on the adjusting beams. Furthermore, the movement of the beam lifting machines allows for changes in the center of gravity due to varying weights, defining lifting zones and making the entire lifting process more stable and safer.

[0009] The beneficial effects of this utility model are: (1) An adjustment beam is installed on the beam lifting machine. The adjustment beam is provided with adjustment holes for adjusting the position of the lifting lugs. The lifting position can be adjusted according to the size and weight of the object being lifted, which meets the needs of multiple beam lifting machines working together and overcomes the defect that the existing beam lifting machine lifting structure cannot lift large equipment; (2) The adjustment beam can be directly connected to the existing beam lifting machine. The structure is simple and easy to use, which further improves the safety performance of the operation; (3) A blocking point is added to the lifting lugs, which is suitable for both wheeled beam lifting machines and rail-mounted beam lifting machines, further increasing the application range of the lifting mechanism.

Each beam lifting machine 2 is provided with a front lifting beam trolley 201 and a rear lifting beam trolley 202. Each adjusting beam 1 is simultaneously connected to the front lifting beam trolley 201 and the rear lifting beam trolley 202 on its corresponding beam lifting machine 2. Each adjusting beam 1 is provided with lifting devices 3 located on both sides of the object to be lifted. Each adjusting beam 1 is also provided with multiple adjusting holes 101 for adjusting the distance between the lifting devices 3 on both sides. The adjusting beams 1 divide the area where the object to be lifted is located into three lifting zones 4. The object to be lifted is provided with a lifting point in each lifting zone 4.

[0020] Each lifting device 3 consists of a mounting part 301 and lifting lugs 302 located on both sides of the mounting part 301. The mounting part 301 is provided with mounting holes 305, which are mounted on adjusting holes 101 via rotating shafts 303. The lifting lugs 302 are connected to lifting points on the object being lifted in the lifting area 4 via steel cables. There are at least two connecting arms 102. The lifting lugs 302 on both sides of the mounting part 301 are respectively connected to lifting points in different lifting areas 4. The adjusting holes 101 on both sides of the adjusting beam 1 are symmetrically arranged, and the adjusting holes 101 on the same side of the adjusting beam 1 are evenly arranged.

[0021] like Figure 5 As shown, both the front lifting beam trolley 201 and the rear lifting beam trolley 202 are equipped with a winch unit and a movable pulley driven by the winch unit. A connecting arm 102 is provided between the adjusting beam 1 and each movable pulley.
