Abstract
The utility model discloses a single-beam crane, which comprises a main beam and end beams, wherein the end beams are connected to the two ends of the main beam respectively; one end or two ends of the main beam are connected with end beam mounting holes through a connecting pipe, which is horizontally arranged on an end part of the main beam, through transition fit; an end part of the connecting pipe extends out of the end beam mounting holes; and the upper part of a limiting block which is fixedly arranged on an outer side face of one end beam extends into a positioning hole which is formed in the connecting pipe. A baffle ring is arranged in an annular groove which is formed in the outer surface of the connecting pipe on the outer side of the limiting block. A beam box of the main beam is of an integral cold-pressed framework structure; a plate face of a beam box top plate is provided with an inner groove along the axial direction; and two sides of a plate surface at the bottom of the beam box are symmetrically arranged tilting downwards the lower space. The single-beam crane has the advantages of simple structure and obvious effect. Through the limiting block which is arranged between the outer side of the end beam and the connecting pipe, the problem of reduction in strength of the main beam caused by transition torsion of the main beam due to horizontal inertial force when the single-beam crane is started or stopped can be solved, and the service life of the main beam is prolonged.
Description
Technical field
The utility model relates to elevator machinery, especially relates to single-beam crane.
Background technology
Single-beam crane is simple in structure with it, practicality is widely used in industrial and mining enterprises, is the requisite lifting appliance of industrial and mining enterprises' Workplace.Single-beam crane is carried the weights such as workpiece by four driving wheels on the end carriage of two ends along the fixed guide parallel motion of both sides.The end carriage at tradition single-beam crane two ends all is to be connected as a single entity by tie bolt and girder, because manufacturing errors, welding stress deformation, long-time use can cause four wheel faces not on same level, one end end carriage adopts the then fine problem that solves self-regulated end carriage level of structure that horizontal connection tube is connected as a single entity girder, but when the hoisting crane band carry when starting or stoping can since horizontal inertial force cause that the girder transition is reversed and cause the decline of girder intensity, reduce girder service life, and have potential safety hazard.
Summary of the invention
The utility model purpose is to provide a kind of use safer failure-free single-beam crane.
For achieving the above object, the utility model can be taked following technical proposals:
Single-beam crane described in the utility model, the end carriage that comprises girder and be connected to described girder two ends, the one or both ends of described girder are connected with end carriage mounting hole transition fit by the connection pipe that is horizontally set on end of main beam, extend outside the end carriage mounting hole described connection pipe end, and the limiting stopper top that is fixed on the end carriage lateral surface extends in the knock hole of offering on the connection pipe.
Be provided with baffle ring in the annular groove of offering on the connection pipe outside face in the described limiting stopper outside.
The beam box of described girder is the integral body framed structure of colding pressing, and is provided with vertically inner groovy on the plate face of described beam box top board, and described beam box bottom plate face bilateral symmetry is obliquely installed downwards.
That the utility model advantage is is simple in structure, effect is remarkable.The limiting stopper that is arranged between the end carriage outside and the connection pipe can prevent that the single-beam crane band carries the girder transition that causes owing to horizontal inertial force when starting or stoping and reverses the girder intensity decline problem that causes, and has prolonged the service life of girder.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the section-drawing of Fig. 1 middle girder beam box.
The specific embodiment
As shown in Figure 1, 2, single-beam crane described in the utility model, the end carriage 2 that comprises girder 1 and be connected to girder 1 two ends, the end carriage 2 of right-hand member is connected as a single entity by bolt and girder, the end carriage 2 of left end is connected with its mounting hole transition fit by the connection pipe 3 that is horizontally set on girder 1 end, extend outside end carriage 2 mounting holes these connection pipe 3 ends, and limiting stopper 4 tops that are fixed on end carriage 2 lateral surfaces extend in the knock hole of offering on the connection pipe 3.Enter after quenching in the top of limiting stopper 4 in the knock hole on the connection pipe 3, can prevent effectively that the single-beam crane band carries when starting or stoping because caused girder intensity decline problem is reversed in the girder transition that horizontal inertial force causes; In the annular groove that connection pipe 3 outside faces in limiting stopper 4 outsides are offered, be provided with baffle ring 5, can guarantee that end carriage 2 accurately locates.The beam box of girder 1 is the integral body framed structure of colding pressing, having overcome traditional girder beam box spicing forming type affects the defective of girder load-bearing, be provided with vertically inner groovy on the plate face of beam box top board 6, beam box bottom plate face 7 bilateral symmetry are obliquely installed downwards, not only be convenient to processing, also played the effect of reinforced rib, made the loading strength of girder better.
