Description

A kind of electric single beam crane connection between girder and carriage structure that can improve stability
Technical field
The utility model belongs to technical field of crane equipment, further belongs to electric single beam crane technical field, specifically It is compact-sized to be related to one kind, connection is reliable, can improve the electric single beam crane connection between girder and carriage structure of stability.
Background technology
Crane is the handling equipment for mitigating heavy manual labor, improving operating efficiency, realizing safety in production.In state In the substance production and logistics of the economic each department of the people, crane is mechanical as crucial process equipment or important auxiliary, Using very extensive.Crane type is various, and electric single beam crane is that one of which is used in relatively broad workshop Lifting equipment.Electric single beam crane has the characteristics that utilization of area rate is high, job area is big, manufacture cost is low, using ten Divide extensive.Electric single beam crane, be it is a kind of by electric block member hangs under single girder, electric block component is completed Rise the light and small bridge crane with trolley travelling function.The electric single beam crane of the prior art, has the following disadvantages:
1st, it is connected between girder and end carriage using end flanges, under normal circumstances, end carriage height 300mm~400mm, and lead Depth of beam is 400mm~1500mm, and when the lifting capacity of crane is larger and span is larger, main depth of beam is higher, in order to It connect, the height of the end point of girder must be reduced to holding depth of beam basically identical with end carriage, it is just easy to use in this way to connect Fishplate bar connects.It is smaller with the connection area of end carriage since the height of girder end point is too small, cause junction stability poor, rise Girder shakes greatly heavy-duty machine in the process of running, and electric block shakes therewith, influences to use.
2nd, manufacture craft is poor, when assembling girder with end carriage, needs after first the span of crane is adjusted, then will connection Plate and Main Girder Welding, once connecting plate is finished with Main Girder Welding, the span of crane will be unable to adjust.
For this purpose, research and development are a kind of compact-sized, connection is reliable, can improve the electric single beam crane girder of stability with End carriage connection structure is the key that solve the problems, such as this.
Utility model content
The purpose of this utility model is to provide a kind of compact-sized, connection is reliable, can improve the electric single-beam of stability Crane girder and end carriage connection structure.
The purpose of this utility model is achieved in that including end carriage, girder, connecting plate, bolt pair, positioning pin, described End carriage on girder is set;Connecting plate is set between the end carriage and girder;The connecting plate and girder are affixed;Institute The middle part setting connecting hole and location hole of the upper surface for the end carriage stated;At the connecting hole and location hole of the end carriage and connecting plate Between setting bolt pair and positioning pin.
Girder is overlapped on end carriage by the utility model, enhances the stability and reliability of connection between girder and carriage. The lap-joint of girder and end carriage sets connecting plate, connecting plate and Main Girder Welding, and connecting hole and location hole are set on connecting plate.End carriage The middle part setting connecting hole and location hole of upper surface, are connected between girder and end carriage by bolt pair.At connection between girder and carriage Main beam section height can according to the tonnage and span of crane calculating depending on, ensure that the stability of connection between girder and carriage And reliability.Meanwhile this solution process is good.
When girder and end carriage assemble, first connecting plate with end carriage with bolt good fortune is connected, girder is then placed in connection On plate, after the span measurement of crane is adjusted, with positioning pin by connecting plate and end carriage pinning, connecting plate is then welded in master Liang Shang.Girder is overlapped on end carriage by the utility model, the main beam section height at connection between girder and carriage can according to rise Depending on the tonnage and span of heavy-duty machine calculate, the stability and reliability of connection between girder and carriage ensure that;The peace of girder and end carriage Good manufacturability is filled, reduces the set-up time, reduces the manufacture cost of crane.The utility model is compact-sized, and connection is reliable, The stability of electric single beam crane connection between girder and carriage can be improved.

Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is former electric single beam crane connection between girder and carriage structure diagram;
Fig. 4 is the schematic top plan view of Fig. 3.
In figure:1- end carriages, 2- girders, 3- connecting plates, 4- bolt pairs, 5- positioning pins.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model is not limited in any way System based on any transformation that the utility model training centre is made, each falls within scope of protection of the utility model.
As shown in figures 1-4, the utility model includes end carriage 1, and girder 2, connecting plate 3, bolt pair 4, positioning pin 5 is described Girder 2 is set on end carriage 1;Connecting plate 3 is set between the end carriage 1 and girder 2;The connecting plate 3 is solid with girder 2 It connects;The middle part setting connecting hole and location hole of the upper surface of the end carriage 1;At the connecting hole and location hole of the end carriage 1 Bolt pair 4 and positioning pin 5 are set between connecting plate 3.
It is welded between the connecting plate 3 and girder 2.
The connecting plate 3 welds after the span of crane is adjusted with girder 2 again.
Connecting hole and location hole on the connecting plate 3 is corresponding with the connecting hole on end carriage 1 and location hole.
The thickness of the connecting plate 3 is 14mm~25mm.
The bolt pair 4 is high-strength bolt pair.
The quantity of the positioning pin 5 is 2~4, and is symmetrically arranged in the both sides of girder 2.
The positioning pin 5 is taper bolt.
The positioning pin 5 is taper pin with internal thread.
The operation principle and the course of work of the utility model:
Girder 2 is overlapped on end carriage 1 by the utility model, enhances stability that girder 2 connect with end carriage 1 and reliable Property.Lap-joint's setting connecting plate 3 of girder 2 and end carriage 1, connecting plate 3 weld with girder 2, connecting hole are set on connecting plate 3 and is determined Position hole.The middle part setting connecting hole and location hole of 1 upper surface of end carriage, are connected between girder 2 and end carriage 1 by bolt pair 4.Girder 2 with 2 profile height of girder of 1 junction of end carriage can depending on the calculating of the tonnage and span of crane, ensure that girder 2 with The stability and reliability that end carriage 1 connects.Meanwhile this solution process is good.
When girder 2 and end carriage 1 assemble, first connecting plate 3 and the bolt pair 4 of end carriage 1 are connected, then put girder 2 It,, then will be even with positioning pin 5 by connecting plate 3 and 1 pinning of end carriage after the span measurement of crane is adjusted on connecting plate 3 Fishplate bar 3 is welded on girder 2.Girder 2 is overlapped on end carriage 1 by the utility model, and girder 2 and the girder 2 of 1 junction of end carriage are disconnected Face height can ensure that stability that girder 2 connect with end carriage 1 and reliably depending on the calculating of the tonnage and span of crane Property;Girder 2 and the mounting process of end carriage 1 are good, reduce the set-up time, reduce the manufacture cost of crane.
