Description

Technical Field

[0001] The present application relates to the technical field of bridge erection equipment, and in particular to a front transverse track of a bridge erection machine. Background Art

[0002] In recent years, my country's highway infrastructure has developed rapidly. A large number of highways, especially high-grade highways, are under construction or planned to be built. In order to shorten the mileage of highways, increase the straightness of the road, and ensure the driving speed, safety and comfort of the highway, highway designs use a large number of bridges to cross valleys and rivers. Moreover, most of the bridges are prefabricated in a centralized manner and then transported to the site for erection and installation to ensure the construction quality of the bridges.

[0003] Reference Figure 1 At present, during the installation of the beam and slab of the bridge erector, the front transverse track is mainly supported by stacking square wood together. The existing technology is as follows Figure 1 This method requires manual lifting of the track onto the cap beam in advance, support with square timber and adjust the track to a horizontal position.

[0004] This simple stacking of square timber support method has a high structural safety risk. In addition, the installation workers have to install and adjust it on the cap beam, which has a high construction safety risk. Moreover, since the horizontal track in front of the bridge erection machine must be kept horizontal, it is cumbersome and difficult to level it with square timber, and the work takes a long time. Utility Model Content

[0005] In order to improve the efficiency of workers' track leveling work, the present application provides a front transverse track of a bridge erecting machine.

[0006] The present application provides a bridge erection machine front transverse track adopting the following technical solution:

[0007] A front transverse track of a bridge erecting machine includes a plurality of telescopic rods placed between the track and a bridge base, wherein the telescopic directions of the telescopic rods are perpendicular to both the bridge base and the track, and the plurality of telescopic rods are parallel to each other. A propulsion device for controlling the telescopic extension of the telescopic rods is provided at one end of the telescopic rods close to the track, and a clamping device for fixing the telescopic rods on the bridge base is provided at one end of the telescopic rods close to the bridge base.

[0008] By adopting the above technical solution, when the front transverse track needs to move upward, the propulsion device can be started, and the propulsion device controls the extension and retraction of the telescopic rod, so that the telescopic rod transmits the thrust to the bridge base through the clamping device, and the bridge base gives a thrust in the opposite direction, so that the front transverse track moves upward. At the same time, since multiple sets of clamping structures and propulsion structures need to be set at the bottom of the front transverse track, it can greatly facilitate the operator to complete the leveling, and improve the efficiency of the workers' track leveling work.

[0009] Optionally, the propulsion device is configured as a cylinder, the telescopic rod includes a movable part and a fixed part, the movable part is slidably connected in the fixed part, and the telescopic end of the cylinder is fixedly connected to the movable part.

[0014] By adopting the above technical solution, when fixing the telescopic rod, the driving assembly can drive the abutment plate to move toward the fixing plate, so that the bridge base is placed between the fixing plate and the abutment plate, and the fixing plate and the abutment plate are both pressed against the bridge base, thereby quickly fixing the telescopic rod on the bridge base.

[0015] Optionally, the driving assembly includes a plurality of electric push rods, the electric push rods are fixedly connected to the mounting plate, the extension and retraction directions of the electric push rods are parallel to the sliding direction of the abutment plate on the mounting plate, and the extension and retraction ends of the electric push rods are fixedly connected to the abutment plate.

[0016] By adopting the above technical solution and controlling the electric push rod, the electric push rod can drive the abutment plate to move and fix the telescopic rod on the bridge base.

[0017] Optionally, a plurality of guide rods are passed through and slidably connected to the mounting plate, the axes of the guide rods are parallel to the telescopic direction of the electric push rod, and one end of the guide rod is fixedly connected to the abutment plate.

[0018] By adopting the above technical solution, the guide rod can provide a guiding effect on the movement of the abutment plate, thereby improving the stability of the movement of the abutment plate.

[0019] Optionally, a plurality of sliding grooves are opened on one side of the mounting plate away from the telescopic rod, and the opening direction of the sliding grooves is the same as the sliding direction of the abutment plate on the mounting plate.

The abutment plate is slidably connected to the mounting plate through the sliding grooves and the slide blocks.

[0020] By adopting the above technical solution, the sliding of the abutment plate on the mounting plate can be achieved through the sliding groove and the slider, and the sliding direction of the abutment plate can be limited by the sliding groove and the slider.

[0021] Optionally, a rubber block is fixedly connected to one side of the fixing plate and the abutting plate that are close to each other.

[0022] By adopting the above technical solution, the friction between the abutment plate and the bridge base layer and between the fixing plate and the bridge base layer can be increased by the rubber block, thereby improving the stability of the telescopic rod on the bridge base layer.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The telescopic rod transmits the thrust to the bridge base through the clamping device, and the bridge base gives a thrust in the opposite direction, so that the front transverse track moves upward.

A propulsion device 5 for controlling the telescopic rod 3 to be extended and retracted is provided at one end of the telescopic rod 3 close to the track 1.

[0037] Reference Figure 2 and Figure 3 The propulsion device 5 is configured as a cylinder 51, the telescopic direction of the cylinder 51 is parallel to the telescopic direction of the telescopic rod 3, the telescopic rod 3 includes a movable part 32 and a fixed part 31, the movable part 32 is slidably connected in the fixed part 31, the telescopic end of the cylinder 51 passes through the fixed part 31 and is fixedly connected to the movable part 32, and the bottom end of the cylinder 51 abuts against the track 1.

[0039] The implementation principle of the embodiment 1 is as follows: when the front transverse track 1 needs to move upward, the claw 41 can be fixed on the bridge base 2, and then the cylinder 51 can be started in sequence to control the telescopic rod 3 to extend and retract, so that the telescopic rod 3 transmits the thrust to the bridge base 2, and the bridge base 2 gives a thrust in the opposite direction, so that the front transverse track 1 moves upward. In this way, the track 1 is leveled.

[0041] The difference from Example 1 is: Figure 4 and Figure 5The clamping device 4 includes a mounting plate 42, which is arranged in an L shape and is fixedly connected to the end of the telescopic rod 3. A fixing plate 43 is fixedly connected to the side of the mounting plate 42 facing the bridge base 2. The fixing plate 43 is located at the end of the mounting plate 42 away from the bending of the mounting plate 42, and the fixing plate 43 is perpendicular to the end face of the mounting plate 42.
