[0002] With the development of transportation, bridge-building machinery and equipment have also developed rapidly. As an indispensable equipment for building highway bridges and railway bridges, bridge-building machines are more and more widely used. The bridge-building machine hoist is an important part of the bridge-building machine and also the main load-bearing component. It plays a very important role in the lifting work of the bridge-building machine.

[0003] At present, the prior art suitable for the lifting beam device of the bridge erection machine usually has a motor that rotates the gear set through a fixed rod, and then rotates the gear column through the gear set to control the rise and fall of the hook. When lubricating the gear set, since the existing bridge erection machine lifting beam device still lubricates the gear set manually, it is relatively cumbersome and the lubrication time is long. There is a problem that the gear column cannot be lubricated automatically. Moreover, when replenishing the lubricating oil into the storage box, since the existing bridge erection machine lifting beam device is provided with a storage box, and lubricating oil is added to the storage box to facilitate the lubrication of the gear set, and the storage box is not provided with a prompt device, the staff cannot clearly know how much lubricating oil is left in the storage box, which further affects the lubrication of the gear set. There is a problem that the storage box lacks a prompt device. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] A gear 1 3 is fixedly connected to the outer side of one end of the lifting column 2, the diameter of the gear 1 3 is smaller than the diameter of the gear 2 4, the length of the push bar 5 is greater than the radius of the gear 2 4, the outer side of the gear 1 3 is meshedly connected to the gear 2 4, one side of the gear 2 4 is fixedly connected to the push bar 5, the outer side of the lifting column 2 is fixedly connected to the first gear 9, the outer side of the first gear 9 is meshedly connected to the second gear 10, the inner wall of the second gear 10 is fixedly connected to the lifting column 2, one end of the lifting column 2 is movably connected to the fixing frame 24, the top of the fixing frame 24 is fixedly installed with a storage box 8, the storage box The inner wall of 8 is fixedly connected with a spring 11, one end of the spring 11 is fixedly connected with an L rod 6, one side of the L rod 6 is fixedly connected with a blocking plate 7, the outer side of the blocking plate 7 is slidably connected with a storage box 8, and the top outer side of the storage box 8 is threadedly connected with a threaded cover 23. Through the arrangement of a motor 1, a lifting column 2, a gear 1 3, a gear 2 4, a pushing bar 5, an L rod 6, a blocking plate 7, a storage box 8, a first gear 9, a second gear 10, and a spring 11, a device suitable for lifting a beam of a bridge erecting machine can lubricate the gear set, thereby avoiding the inability to automatically lubricate the gear set.

[0033] When in use, the control room starts the motor 1 to reverse through the control box 19, and the motor 1 drives the lifting column 2, and the lifting column 2 drives the first gear 9. The first gear 9 is meshed with the second gear 10 to make another lifting column 2, and the rotation of the lifting column 2 makes the lifting rope 12 sent down, so that the hook 13 moves downward, the lifting column 2 drives gear 1 3, gear 1 3 drives gear 2 4, and the pushing bar 5 rotates synchronously with the gear 2 4, so that when the gear 2 4 rotates, the pushing bar 5 pushes the L rod 6 within a certain angle range, and the spring 11 contracts under the pressure of the L rod 6, so that the blocking plate 7 also moves accordingly, so that the lubricating oil in the storage box 8 lubricates the first gear 9 and the second gear 10 through the oil drain port. When the pushing bar 5 is not within a certain angle range, the spring 11 pushes the L rod 6 back to its original position, blocks the oil drain port on the storage box 8, and no longer lubricates the first gear 9 and the second gear 10. Therefore, the first gear 9 and the second gear 10 can be lubricated during work.

[0034] Example 2

[0035] See also Figures 1 to 9 The utility model provides a technical solution: a device for lifting a beam of a bridge erecting machine, comprising a fixing frame 24, a motor 1 is fixedly installed on the outer side of the fixing frame 24, a lifting column 2 is fixedly connected to the output shaft of the motor 1, a lifting rope 12 is fixedly connected to the outer side of the lifting column 2, and a hook 13 is fixedly connected to one end of the lifting rope 12;

[0036] The inner wall of the storage box 8 is fixedly connected with a fixed column 21, the inner wall of the fixed column 21 is fixedly connected with a sealing ring 20, the inner wall of the sealing ring 20 is slidably connected with a sliding column 15, the inner wall of the fixed column 21 is slidably connected with the sliding column 15, one end of the sliding column 15 is fixedly connected with a first electrode block 16, the outer side of the first electrode block 16 is slidably connected with the fixed column 21, the inner wall of the fixed column 21 is fixedly connected with a second electrode block 17, the inner wall of the fixed column 21 is fixedly connected with a third electrode block 18, one end of the sliding column 15 is fixedly connected with a buoyancy plate 14, and the buoyancy plate The shape of 14 is circular, there are two buoyancy plates 14, the number of sliding columns 15 is the same as the number of buoyancy plates 14, the inner wall of the buoyancy plate 14 is slidably connected with a limiting rod 22, and one end of the limiting rod 22 is fixedly connected with a storage box 8.

[0037] During use, when the lubricating oil in the storage box 8 is flush with the bottom of the buoyancy plate 14, as the lubricating oil in the storage box 8 continues to decrease, the buoyancy plate 14 moves downward as the lubricating oil decreases. When the lubricating oil in the storage box 8 is reduced to a certain amount, the first electrode block 16 on the sliding column 15 is in contact with the second electrode block 17, and then the information is fed back to the control room through the control box 19, prompting the staff to replenish the lubricating oil in the storage box 8. When the lubricating oil in the storage box 8 is used up, the bottom of the buoyancy plate 14 is in contact with the bottom wall of the storage box 8, and the first electrode block 16 is in contact with the third electrode block 18, and then the information is fed back to the control room through the control box 19.
