Description

Technical Field

[0001] This invention relates to the field of auxiliary installation of bridge cranes, and more particularly to an auxiliary device for the installation of bridge cranes. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Because their ends rest on tall concrete pillars or metal supports, resembling a bridge, the bridge frame of a bridge crane runs longitudinally along rails laid on elevated platforms on both sides. This allows for full utilization of the space beneath the bridge frame for material handling, without obstruction from ground equipment. It is the most widely used and numerous type of lifting machinery. A bridge crane, also known as an overhead crane, has its bridge frame running longitudinally along rails laid on elevated platforms on both sides, while the lifting trolley runs laterally along rails laid on the bridge frame, forming a rectangular working area. This allows for full utilization of the space beneath the bridge frame for material handling, without obstruction from ground equipment. This type of crane is widely used in indoor and outdoor warehouses, factories, docks, and open-air storage yards.

[0003] Bridge cranes consist of main beams and end beams, and are divided into two types: single main beam bridges and double beam bridges. A single main beam bridge consists of a single main beam and end beams located on both sides of the span, while a double beam bridge consists of two main beams and end beams. The main beams and end beams are rigidly connected, and wheels are installed at both ends of the end beams to support the bridge frame to run on the elevated structure. Rails are welded on the main beams for the crane trolley to run on.

[0004] After the main beam is on the track, the next step is to connect the end beams. In the past, when hoisting the main beams, due to the height of the factory building or the influence of the truck crane, the two main beams could not be hoisted to the appropriate installation position at the same time. When the end beams were connected, the two main beams had to be pulled closer by a hand hoist, and then jacks were used to install high-strength bolts. Due to the large frictional resistance and slow sliding, the process of pulling them closer by the hoist was very labor-intensive and time-consuming. When the main beams were far apart, it could take several hours. Therefore, this method was not safe and was not efficient.

[0005] Therefore, it is necessary to provide an auxiliary device for installing bridge cranes to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides an auxiliary device for the installation of bridge cranes, which solves the problem that when connecting the end beams, it is necessary to use a hand-operated hoist to pull the two main beams closer together and then use a jack to install high-strength bolts. Due to the large frictional resistance and slow sliding, the process of pulling the two main beams closer together with the hoist is very labor-intensive and time-consuming. When the distance between the main beams is large, it can take several hours. Therefore, this method is not safe and has low efficiency.

[0007] To solve the above-mentioned technical problems, the present invention provides an auxiliary device for the installation of a bridge crane, comprising: a first bridge frame, a second bridge frame, a pulling device, and a limiting device.

[0008] The pulling device is disposed on both sides of the top of the first cable tray. The pulling device includes a first horizontal plate, a first vertical plate, a mounting block, a lifting component, and a limiting block. The first horizontal plate is disposed on both sides of the top of the first cable tray. Two first vertical plates are respectively fixedly installed on both sides of the first horizontal plate. The mounting block is fixedly installed in the middle of the top of the first horizontal plate. The lifting component is fixedly installed in the middle of one side of the outer surface of the mounting block. The limiting block is fixedly installed at one end of the output shaft of the lifting component.

[0009] The limiting device is disposed on both sides of the top of the second cable tray. The limiting device includes a second horizontal plate, a second vertical plate, a pulling block and a placement hole. The second horizontal plate is disposed on both sides of the top of the second cable tray. Two second vertical plates are respectively fixedly installed on both sides of the outer surface of the second horizontal plate. The pulling block is fixedly installed in the middle of the top of the second horizontal plate. The placement hole is opened in the middle of the top of the pulling block.

[0010] Preferably, the first cable tray includes a main beam, end beams and threaded holes, with two end beams fixedly installed on both sides of the main beam, and two threaded holes respectively opened on both sides of the outer surface of the end beams.

[0011] Preferably, the first cable tray and the second cable tray have the same structure.

[0012] Preferably, the lifting component adopts a hydraulic cylinder structure.

[0013] Preferably, the first vertical plate is bolted to the outer surface of the end beam.

[0014] Preferably, a connecting block is provided on one side of the outer surface of the mounting block, a mounting plate is fixedly installed on the top of the connecting block, a driving component is fixedly installed on one side of the outer surface of the connecting block, a threaded rod is fixedly connected to the output shaft end of the driving component, a limiting plate is rotatably installed on the outer surface of one end of the threaded rod, and a limit rod is fixedly installed on the bottom of one side of the connecting block.

[0015] Preferably, the outer surface of the threaded rod is threaded with a limiting plate.

[0016] Compared with related technologies, the auxiliary device for installing a bridge crane provided by the present invention has the following advantages:

[0017] This invention provides an auxiliary device for installing a bridge crane. A pulling device and a limiting device are first installed on the first and second bridge frames respectively via bolts through threaded holes. The output shaft of the lifting component of the pulling device pulls the limiting block, which in turn moves the limiting device and the second bridge frame, causing the second bridge frame to move closer to the first bridge frame. This device has a simple structure and strong practicality. During adjustment, the pulling device and the limiting device are installed using the threaded holes of the mounting end beam connecting device. The operator only needs to control the extension and retraction of the output shaft of the lifting component to achieve docking or separation of the limiting block and the placement hole. The operation is simple and quick, not only solving the problems of low safety and low efficiency in traditional installation methods, but also improving the stability and flexibility of the installation process, demonstrating significant technical effects and practical value.

Figure 3 for Figure 1 The enlarged schematic diagram of part A is shown.

[0027] An auxiliary device for installing a bridge crane includes: a first bridge frame 1, a second bridge frame 2, a pulling device 3, and a limiting device 4.

[0028] The pulling device 3 is disposed on both sides of the top of the first cable tray 1. The pulling device 3 includes a first horizontal plate 31, a first vertical plate 32, a mounting block 33, a lifting member 34, and a limiting block 35. The first horizontal plate 31 is disposed on both sides of the top of the first cable tray 1. The two first vertical plates 32 are respectively fixedly installed on both sides of the first horizontal plate 31. The mounting block 33 is fixedly installed in the middle of the top of the first horizontal plate 31. The lifting member 34 is fixedly installed in the middle of one side of the outer surface of the mounting block 33. The limiting block 35 is fixedly installed at one end of the output shaft of the lifting member 34.

[0029] The limiting device 4 is disposed on both sides of the top of the second cable tray 2. The limiting device 4 includes a second horizontal plate 41, a second vertical plate 42, a pulling block 43, and a placement hole 44. The second horizontal plate 41 is disposed on both sides of the top of the second cable tray 2. The two second vertical plates 42 are respectively fixedly installed on both sides of the outer surface of the second horizontal plate 41. The pulling block 43 is fixedly installed in the middle of the top of the second horizontal plate 41. The placement hole 44 is opened in the middle of the top of the pulling block 43.

[0030] The first cable tray 1 includes a main beam 101, end beams 102 and threaded holes 103. The two end beams 102 are fixedly installed on both sides of the main beam 101, and the two threaded holes 103 are respectively opened on both sides of the outer surface of the end beams 102.

[0031] The first cable tray 1 and the second cable tray 2 have the same structure.

[0032] The lifting component 34 adopts a hydraulic cylinder structure.

[0033] The first vertical plate 32 is bolted to the outer surface of the end beam 102.

[0034] The output shaft of the lifting member 34 is placed from top to bottom inside the placement hole 44, so that the limiting block 35 is on the outer surface of the pulling block 43, which restricts the movement of the output shaft of the lifting member 34 towards the first bridge 1, and the limiting block 35 pulls the second bridge 2 towards the first bridge 1.

[0035] The working principle of the auxiliary device for bridge crane installation provided by this invention is as follows:

[0036] During operation, firstly, a limiting device 4 is installed on the surface of the second cable tray 2, and then a pulling device 3 is installed. The pulling device 3 is installed on the top of the end beam 102, the first horizontal plate 31 is attached to the top of the end beam 102, and the two first vertical plates 32 are respectively attached to the two sides of the outer surface of the end beam 102, so that the first vertical plates 32 can be installed on the outer surface of the end beam 102 by bolts. The output shaft of the lifting component 34 is placed in the placement hole 44 from top to bottom.

[0037] The output shaft of the lifting component 34 retracts into the cylinder body, and the output shaft drives the limiting block 35 to move. The limiting block 35 pulls the pulling block 43 toward the first bridge frame 1, so that the first bridge frame 1 and the second bridge frame 2 are close together. Then the pulling device 3 and the limiting device 4 are disassembled to expose the threaded hole 103. Then the end beam connecting device is installed on the end beam surface of the first bridge frame 1 and the second bridge frame 2 by bolts.

[0038] Compared with related technologies, the auxiliary device for installing a bridge crane provided by the present invention has the following advantages:

[0039] This invention provides an auxiliary device for installing a bridge crane. A pulling device 3 and a limiting device 4 are first installed on the first bridge frame 1 and the second bridge frame 2 respectively via threaded holes 103 using bolts. The output shaft of the lifting member 34 of the pulling device 3 pulls the limiting block 35 to move. The limiting block 35 then moves the limiting device 4 and the second bridge frame 2, causing the second bridge frame 2 to move closer to the first bridge frame 1. This device has a simple structure and strong practicality. During adjustment, the pulling device 3 and the limiting device 4 are installed using the threaded holes 103 of the end beam connecting device. The operator only needs to control the extension and retraction of the output shaft of the lifting member 34 to achieve docking or separation of the limiting block 35 and the placement hole 44. The operation is simple and quick, not only solving the problems of low safety and low efficiency in traditional installation methods, but also improving the stability and flexibility of the installation process, demonstrating significant technical effects and practical value.

[0040] Second Embodiment

[0041] Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application providing an auxiliary device for installing a bridge crane, the second embodiment of this application proposes another auxiliary device for installing a bridge crane. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0042] Specifically, the second embodiment of this application provides an auxiliary device for installing a bridge crane, which differs in that the auxiliary device for installing a bridge crane has a connecting block 5 on one side of the outer surface of the mounting block 33, a mounting plate 6 fixedly mounted on the top of the connecting block 5, a driving component 7 fixedly mounted on one side of the outer surface of the connecting block 5, a threaded rod 8 fixedly connected to the output shaft end of the driving component 7, a limiting plate 11 rotatably mounted on the outer surface of one end of the threaded rod 8, and a limit rod 10 fixedly mounted on the bottom of one side of the connecting block 5.

[0043] The outer surface of the threaded rod 8 is threaded with a limiting plate 11.

[0044] The limiting plate 11 has threaded holes and limiting holes on its surface. It is threadedly engaged with the outer surface of the threaded rod 8 through the threaded holes and sleeved on the outer surface of the limiting rod 10 through the limiting holes, so that the limiting plate 11 can only slide and cannot rotate.

[0045] Mounting plate 6 is bolted to the side of mounting block 33, so that connecting block 5 is mounted on top of first horizontal plate 31.

[0046] The working principle of the auxiliary device for bridge crane installation provided by this invention is as follows:

[0047] During operation, the output shaft of the drive component 7 first rotates, causing the threaded rod 8 to rotate. The threaded rod 8 rotates and engages the limiting plate 11. After the limiting plate 11 slides on the surface of the limiting rod 10 to a suitable position, the second bridge frame 2 is controlled to move. During the movement of the end beam, it is observed whether it is in contact with the limiting plate 11.

[0048] Compared with related technologies, the auxiliary device for installing a bridge crane provided by the present invention has the following advantages:

[0049] This invention provides an auxiliary device for installing a bridge crane. The output shaft of a drive unit 7 rotates, causing a threaded rod 8 to rotate. The rotating threaded rod 8 engages a limiting plate 11. After the limiting plate 11 moves to a suitable position via a limit rod 10, the output shaft of a lifting unit 34 drives a limiting block 35 to pull the second bridge frame 2. The limiting plate 11 pre-limits the movement range of the second bridge frame 2, ensuring that it does not shift during the pulling process, thus improving installation accuracy and stability. During the pulling process, the operator only needs to observe the position of the limiting plate 11 to pre-limit the movement distance and maintain the accuracy of the distance between the second bridge frame 2 and the first bridge frame 1. This allows the operator to determine whether the second bridge frame 2 has reached the predetermined position, greatly simplifying the operation process and improving work efficiency.
