Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
A trolley rail of a bridge crane is shown in figures 1-2. Including transversely setting up first track 2 and second track 3 on crossbeam 1, first track 2 and second track 3 all pass through track clamp plate 11 fixed connection on crossbeam 1. The inner of first rail 2 and second rail 3 is in the same place through thermite welding, first rail 2, the top surface of second rail 3 and face of welding is located same horizontal face, one side of 1 top surface of crossbeam is connected with backup pad 4 perpendicularly, backup pad 4 is equipped with one section clearance with first rail 2 outer end, the width in clearance is confirmed according to the total inflation length of first rail 2 and second rail 3 in summer, horizontal fixedly connected with slide rail 8 on first rail 2, the cooperation is equipped with slider 9 on the slide rail 8, slider 9 passes through connecting plate 10 fixed connection with activity car bumper 5. The movable car stop 5 is fixedly connected with the supporting plate 4 through a spring 6, and the outer end of the second track 3 is vertically connected with a fixed car stop 7.
When the device is used, as the first track 2 and the second track 3 are welded and connected and the welding surface and the first track 2 and the second track 3 are positioned on the same transverse surface, therefore, the trolley can stably move from the first track 2 to the second track 3, the trolley is prevented from impacting the gap between the first track 2 and the second track 3 to cause the crack of the cover plate, because the supporting plate 4 is separated from the outer end of the first track 2 by a gap, the expansion with heat and the contraction with cold of the connected first track 2 and the second track 3 can be satisfied, the movable car bumper 5 is connected on the first track 2 in a sliding way, so that the blocking effect of the movable car bumper 5 on the car can be ensured, the wheels of the car can be prevented from sinking into the gap between the supporting plate 4 and the first track 2, and the movable bumper 5 and the supporting plate 4 are fixedly connected through the spring 6, so that the return of the movable bumper 5 can be ensured, and meanwhile, the shock absorption effect on the trolley can be realized. Wherein the movable stop 5 can move transversely along the first rail 2 under the limitation of the slide rail 8.
The movable bumper 5 is in clearance fit with the first rail 2. Thereby the activity car bumper 5 can effectually prevent that the friction from appearing in the top surface of activity car bumper 5 and first track 2 when removing, and then prevents that the first track 2 of activity car bumper 5 wearing and tearing from.
One side of the fixed car bumper 7 facing the movable car bumper 5 is provided with a groove, a buffer rod 12 is transversely arranged in the groove, and the movable end of the buffer rod 12 faces the movable car bumper 5 and is fixedly connected with a baffle. The buffer rod 12 can buffer the trolley when the trolley moves to the side of the fixed baffle plate, so that the impact force of the trolley on the fixed baffle plate is reduced, and the stress area of the baffle plate can be increased.
