Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to an assembled generator tray for a bridge erection machine. Background Art

[0002] A bridge-erecting machine is a type of crane specifically designed to place prefabricated beams onto prefabricated bridge piers. Its primary function is to lift beams, transport them to a designated location, and then lower them. Bridge-erecting machines play a crucial role in modern bridge construction, particularly in the construction of bridges with small spans. Their efficiency makes them a common feature of standard bridge designs. Bridge-erecting machines typically need to be disassembled for transportation to the construction site, where they must be reassembled for operation.

[0003] In bridge construction, the bridge-erecting crane is a critical piece of equipment, and its generator is a vital power source to ensure the stable operation of the entire machine. However, according to traditional designs, the generator is often mounted on the bridge deck and cannot move with the entire crane during span construction, resulting in numerous inconveniences during transportation and installation. Some bridge-erecting cranes have a generator mounting plate fixed to the crane's crossbeam, allowing the generator to move with the entire crane.

[0004] However, the position and size of the generator mounting base plate on the common bridge-building machine are fixed, which cannot meet the installation requirements of bridge-building machine generators of different models or specifications. As a result, when installing bridge-building machine generators of different models or specifications, different generator mounting base plates need to be installed, which increases production costs and reduces work efficiency. In view of this, the present application proposes an assembled generator tray for a bridge-building machine. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an assembled generator tray for a bridge-building machine, which has the advantages of being able to adapt to generators of different models. It solves the problem that the position and size of the generator mounting base plate on the common bridge-building machine are fixed, and it cannot meet the installation requirements of bridge-building machine generators of different models or specifications. As a result, when installing bridge-building machine generators of different models or specifications, different generator mounting base plates need to be installed, which increases production costs and reduces work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled generator tray for a bridge-building machine, comprising an operating platform, a tray fixedly mounted on the top of the operating platform, limit plates fixedly mounted on the two opposite inner side walls of the tray, two sliding base plates slidably mounted between the inner bottom wall of the tray and the limit plate, two adjusting screws fixedly mounted on the top of the sliding base plate, two adjusting nuts threadedly mounted on the surface of the adjusting screws, adjustable support plates slidably mounted on the surfaces of the two adjusting screws, and the adjustable support plate is located between the two adjusting nuts.

[0007] Furthermore, a plurality of positioning holes are provided on the top of the limiting plate, a through hole matching the positioning holes is provided on the top of the sliding base plate, a positioning pin is passed through the top of the limiting plate, and the positioning pin slides through the sliding base plate.

[0008] Furthermore, a suspension rod is fixedly installed on the top of the operating platform, a flange is fixedly installed on the top of the suspension rod, a U-shaped threaded rod is passed through the bottom of the flange, and a locking nut is threadedly installed on the surface of the U-shaped threaded rod above the flange.

[0009] Furthermore, the number of the suspension rods is six, and the six suspension rods are divided into two rows, and the flange is located on the opposite side of the two rows of suspension rods.

[0010] Furthermore, two U-shaped threaded rods are passed through the bottom of one of the flanges, and the crossbeam of the bridge-building machine is passed through between the U-shaped threaded rods and the flange.

[0011] Furthermore, the operating platform includes a frame and a supporting steel mesh fixedly installed on the top of the frame. A guardrail is fixedly installed on the top of the frame, and an upper and lower opening are opened on one side of the guardrail.

[0012] Furthermore, a ladder aligned with the upper and lower openings is fixedly installed on one side of the operating platform, and a sewage pipe is fixedly installed on one side of the tray, and the sewage pipe extends to the outside of the guardrail.

[0013] Compared with the prior art, the present invention provides an assembled generator tray for a bridge erection machine, which has the following beneficial effects:

[0014] The assembled generator tray for a bridge crane is provided with a limit plate on the inner side wall of the tray, two sliding bottom plates are slidably installed between the inner bottom wall of the tray and the limit plate, an adjusting screw is provided on the top of the sliding bottom plate, and an adjustable support plate is slidably installed on the surface of the adjusting screw. The spacing of the adjustable support plates is adjusted by the sliding bottom plate to adapt to generators of different models and specifications, and the height of the adjustable support plate is adjusted by adjusting the nut, and the generator is installed on the top of the adjustable support plate. This solves the problem that the position and size of the generator mounting bottom plate on a common bridge crane are fixed, and it cannot meet the installation requirements of bridge crane generators of different models or specifications, resulting in the need to install different generator mounting bottom plates when installing bridge crane generators of different models or specifications, which not only increases production costs but also reduces work efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 4An assembled generator tray for a bridge erection machine includes an operating platform 1, a tray 2 fixedly mounted on the top of the operating platform 1, limit plates 3 fixedly mounted on the two opposite inner side walls of the tray 2, two sliding base plates 4 slidably mounted between the inner bottom wall of the tray 2 and the limit plates 3, two adjusting screws 5 fixedly mounted on the top of the sliding base plates 4, two adjusting nuts 6 threadedly mounted on the surface of the adjusting screws 5, and adjustable support plates 7 slidably mounted on the surfaces of the two adjusting screws 5, the adjustable support plates 7 being located between the two adjusting nuts 6. The spacing between the two adjustable support plates 7 is adjusted by moving the sliding base plate 4 so that the two adjustable support plates 7 are located at the bottom mounting position of the generator, and then the height of the adjustable support plates 7 is adjusted by the two adjusting nuts 6 to ensure that the generator is placed horizontally on the tray 2.

[0022] The top of the limiting plate 3 is provided with a plurality of positioning holes 31, and the top of the sliding base plate 4 is provided with through holes that match the positioning holes 31. A positioning pin 8 is passed through the top of the limiting plate 3, and the positioning pin 8 slides through the sliding base plate 4. After the position of the sliding base plate 4 is determined, the positioning pin 8 is passed through the sliding base plate 4 and the limiting plate 3 to fix the position of the sliding base plate 4.

[0023] At the same time, a suspension rod 9 is fixedly installed on the top of the operating platform 1, a flange 10 is fixedly installed on the top of the suspension rod 9, a U-shaped threaded rod 11 is passed through the bottom of the flange 10, and a locking nut 12 is threadedly installed on the surface of the U-shaped threaded rod 11 above the flange 10.

[0024] There are six suspension rods 9 , which are divided into two rows. The flange 10 is located on the opposite side of the two rows of suspension rods 9 .

[0025] Secondly, two U-shaped threaded rods 11 are passed through the bottom of a flange 10, and the crossbeam of the bridge erection machine is passed through the U-shaped threaded rods 11 and the flange 10.
