[0002] Single-beam crane usually refers to single-beam bridge crane, which is a lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. Its two ends are located on tall concrete columns or metal brackets, shaped like a bridge. The bridge of the single-beam crane is equipped with end beams at both ends, and motor-driven rollers are installed on the end beams. The rollers run longitudinally along the tracks laid on the elevated platforms on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and largest type of lifting machinery.

[0003] At present, the commonly used end beams are prone to collision when moving to the end of the track. Generally, a buffer structure made of polyurethane material is installed at both ends of the end beam. However, after long-term use, the buffer block has multiple collisions, causing the buffer block to be worn or even damaged, which affects the buffering effect of the device, and the buffer block is not easy to disassemble and replace.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution, an end beam buffer device of a single-beam crane, the end beam body 1 includes a beam body 1.1 and a connecting plate 1.5 arranged in the middle of the top surface of the beam body 1.1 and fixedly connected to the end of the crane bridge, the two ends of the beam body 1.1 are respectively provided with cavities 1.1.1 along the vertical direction, and the two cavities 1.1.1 are respectively rotatably installed with support wheels 1.2 and driving wheels 1.3, and the front side wall of the beam body 1.1 is provided with a driving device 1.4 for driving the driving wheel 1.3 to rotate. Among them, four fixing screw holes 1.1.2 are evenly arranged along the circumferential direction on the central periphery of the two end surfaces of the beam body 1.1. That is, the two ends of the bridge of the single-beam crane are respectively fixed to the connecting plate 1.5 with bolts, the support wheel 1.2 and the driving wheel 1.3 are respectively supported on the track, and the driving device 1.4 includes a motor and a reducer to realize the longitudinal movement of the end beam body 1 carrying the bridge along the track.

[0026] The buffer support 2 includes a fixing bolt 2.1 threadedly sleeved in the fixing screw hole 1.1.2, a collar 2.2 rotatably sleeved on the fixing bolt 2.1 near the outer end, a sleeve 2.3 radially fixed to the outer peripheral wall of the collar 2.2, a spring 2.4 sleeved in the sleeve 2.3, a circular plate 2.5 slidably sleeved on the outer end of the inner cavity of the sleeve 2.3, and an ear plate 2.6 fixed to the outer edge of the circular plate 2.5. The sleeve 2.3 is provided with a sliding groove 2.3.1 along its axial direction for slidingly engaging with the ear plate 2.6.

[0027] The mounting seat 4 comprises a cylindrical shell 4.1, four ear plates 4.2 uniformly fixed to the periphery of the center of the end surface of the cylindrical shell 4.1 along the circumferential direction, and a limiting bolt 4.3 threadedly sleeved on the middle part of the outer peripheral wall of the cylindrical shell 4.1 along the radial direction.

[0028] The inner end of the connecting rod 3 is hinged to the ear plate 1 2.6, and the outer end of the connecting rod 3 is correspondingly hinged to the ear plate 2 4.2, so that the inner end of the connecting rod 3 is inclined outward relative to the outer end.
