Description
Technical field
The utility model is related to crane fields, and in particular to a kind of gantry crane.
Background technology
The cross-arm of traditional gantry crane is integrated with Main Girder Welding so that the product size of gantry crane width direction
Larger, transport is extremely inconvenient, and when especially traditional gantry crane is exported, occupied space is larger, transport space utilization rate
Relatively low, transportation cost is higher.
To solve the above problems, Authorization Notice No. CN206318617U, the utility model of authorized announcement date 2017.07.11
Patent discloses a kind of single girder gantry crane and its girder device, and the front and rear fixing sleeve extended of both ends setting of girder is fixed
Set is welded below girder, and the front and rear end carriage extended is coated in fixing sleeve, and the rear and front end of crossbeam is pierced by from fixing sleeve,
It is pierced by cross-arm of the part to be overhung at girder side.
The gantry crane of above structure since cross-arm width is longer, generates high torque after cross arm end stress, transmit
To cross-arm fixing sleeve and Main Girder Welding, welding structure is easily damaged and then influences the stable connection of cross-arm structure.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of gantry cranes of cross-arm structure stable connection.
To achieve the above object, the technical solution that the utility model is taken is：A kind of gantry crane, including girder, horizontal stroke
Load fixing sleeve and cross-arm, cross-arm fixing sleeve are fixedly connected on girder, and cross-arm is threaded through in cross-arm fixing sleeve, and cross-arm is consolidated with cross-arm
Surely releasable connection is covered, the both ends of cross-arm fixing sleeve are connected separately with first connecting rod and second connecting rod, first connecting rod and second connecting rod
It is fixedly connected with girder.
First connecting rod and second connecting rod are located at the same side of cross-arm.
Cross-arm is fixed with multiple and is set along girder length direction uniform intervals.
First connecting rod and second connecting rod one end are connect with the end of cross-arm fixing sleeve, the other end and adjacent cross-arm fixing sleeve
End connection.
The gantry crane of the utility model, including girder, cross-arm fixing sleeve and cross-arm, cross-arm fixing sleeve is fixedly connected on
On girder, cross-arm is threaded through in cross-arm fixing sleeve, and cross-arm and cross-arm fixing sleeve releasable connection, the both ends of cross-arm fixing sleeve connect respectively
First connecting rod and second connecting rod are connected to, first connecting rod and second connecting rod are fixedly connected with girder.First connecting rod and second connecting rod
Stable triangular structure is formed with cross-arm fixing sleeve, it, can be by first connecting rod and when cross-arm fixing sleeve bears high torque
Two connecting rods are transferred on girder, and the weld of cross-arm fixing sleeve and girder is avoided to bear high torque and damage.
Description of the drawings
Fig. 1 is the structure diagram of specific embodiment of the utility model one；
Fig. 2 is the structure diagram of the first cross-arm 4 in Fig. 1；
Fig. 3 is the structure diagram that Fig. 1 extracts the first cross-arm 4 and the second cross-arm 5 out.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The specific embodiment one of the gantry crane of the utility model, as shown in Figure 1 to Figure 3, including girder 1, first
Cross-arm fixing sleeve 2, the second cross-arm fixing sleeve 3, the first cross-arm 4 and the second cross-arm 5, the first cross-arm 4 are threaded through the first girder and fix
In set 2, the second cross-arm 5 is threaded through in the second girder fixing sleeve 3, and the first cross-arm 4 and the first girder fixing sleeve 2 are equipped with corresponding
Bolt hole, also be provided with corresponding bolt hole, the first cross-arm 4 and the first girder on the second cross-arm 5 and the second girder fixing sleeve 3
Fixing sleeve 2 is by bolt releasable connection, and the second cross-arm 5 and the second girder fixing sleeve 3 are also by bolt releasable connection, first connecting rod
6 one end are connect with 2 end of the first cross-arm fixing sleeve, and the other end is connect with 3 end of the second cross-arm fixing sleeve, 7 one end of second connecting rod
It is connect with 2 end of the first cross-arm fixing sleeve, the other end is connect with 3 end of the second cross-arm fixing sleeve, first connecting rod 6 and second connecting rod
7 centre is fixed on girder 1.
First connecting rod 6 and second connecting rod 7 form stable with the first cross-arm fixing sleeve 2 and the second cross-arm fixing sleeve 3 respectively
Triangular structure, can be by first connecting rod 6 and when the first cross-arm fixing sleeve 2 and the second cross-arm fixing sleeve 3 bear high torque
Two connecting rods 7 are transferred on girder 1, and the first cross-arm fixing sleeve 2 and the weld of the second cross-arm fixing sleeve 3 and girder 1 is avoided to bear
High torque and damage.
Preferably, first connecting rod 6 and second connecting rod 7 are arranged on the same side, first connecting rod 6 and relative to the first cross-arm 4
Two connecting rods 7 are also disposed at the same side relative to the second cross-arm 5, then first connecting rod 6 and second connecting rod 7 are fixed respectively with the first cross-arm
2 and second cross-arm fixing sleeve 3 of set forms stable triangular structure, so as to ensure that the first cross-arm fixing sleeve 2 and the second cross-arm are consolidated
Surely the load stability of set 3, certainly, in the other embodiment of the utility model, first connecting rod 6 and second connecting rod 7 can set up separately
In the both sides of the first cross-arm 4 or the second cross-arm 5.
Preferably, other cross-arms are additionally provided on girder 1, the spacing between each cross-arm is consistent, multiple cross-arms collaboration supports, can
It is further ensured that the load-carrying properties of girder 1.
