Technical Field
The utility model relates to a hoisting equipment field especially relates to a bridge crane is with end beam assembly.
Background
The crane is a multi-action crane for vertically lifting and horizontally carrying heavy objects in a certain range, and the bridge crane is a bridge crane, also called a crown block, in which a bridge runs on an overhead rail. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated frames at two sides, and the end beams of the bridge crane transversely move along the tracks laid on the bridge frame through the travelling wheels to form a rectangular working range, so that the space below the bridge frame can be fully utilized to hoist materials without being hindered by ground equipment.
In the prior art, boring machining is needed on the end part of the end beam assembly travelling wheel, the machining period is long, end beam stock is often needed for matching with the production period, and the stock pressure is large due to the fact that the length of the end beam is long and the stock specifications are many, namely the common specifications are generally 3.5 meters, 4 meters, 4.5 meters, 5 meters, 5.5 meters and the like. Thus, there is room for improvement in prior art end beam structures.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a bridge crane is with end beam assembly can show the stock pressure when reducing the bore hole operation, reduction in production cost.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides an end beam assembly for bridge crane, characterized by: including the roof beam body and two end beam heads, two end beam head and roof beam body between be split type structure, and two end beam heads install respectively and fix on the both ends position of the roof beam body to and set up the mounting hole that supplies the walking wheel installation on the end beam head.
Preferably, the end beam heads are welded to two ends of the beam body.

Preferably, the mounting hole is of a radial opening type structure.
Preferably, a baffle plate used for shielding the travelling wheels is arranged at one end of the end beam head back to the beam body.
The utility model has the advantages that: because the end beam head and the beam body are of a split structure, only the end beam head is operated during boring operation, and the end beam head is fixed on the beam body after boring is finished; in the process:
1. the volume of the end beam head is obviously smaller than the whole volume of the end beam, so that the inventory pressure during boring operation can be obviously reduced, and the production cost is reduced;
2. the end beam head is relatively small in size, so that the convenience of boring is remarkably improved; 3. the end beam heads can be mounted on beams of different lengths to form different dimensional specifications.

Detailed Description
The end beam assembly for a bridge crane according to the present invention will be further described with reference to fig. 1 to 3.
The utility model provides an end beam assembly for bridge crane, characterized by: including the roof beam body 1 and two end beam heads 2, two end beam head 2 and roof beam body 1 between be split type structure, and two end beam heads 2 install respectively and fix on the both ends position of the roof beam body 1 to and set up the mounting hole 22 that supplies walking wheel 3 to install on end beam head 2.
Specifically, the beam body 1 is formed by two webs and a top plate and a bottom plate welded between the two webs, and similarly, the end beam head 2 is also formed by two webs 24 and a top plate 25 and a bottom plate 26 welded between the two webs 24. The length of the web of the end beam head 2 is less than the length of the web of the beam body 1.
The end beam heads are welded at two ends of the beam body 1. Two webs of the end beam head 2 extend into the space between two webs of the beam body 1, so that the two webs of the end beam head 2 are respectively attached to the two webs of the beam body 1, and then welding operation is carried out along the web end surface of the beam body 1, so that the end beam head 2 and the beam body 1 are fixed.
Further, the end of the beam body 1 is provided with a special-shaped end surface 11 capable of increasing the length of the welding seam. The web end face of the beam body 1 is provided with the grooves, so that the edges of the two grooves are increased on the web end face of the beam body 1, the length of the edges of the web is increased, the length of a welding seam is further increased, and the welding strength is improved.
As another embodiment of this embodiment, the web of the end beam head 2 can also be connected to the end position of the web of the beam body 1 by adopting a bolt fixing connection mode.
The mounting hole 22 is of a radial opening type structure, a notch 21 is formed in the lower vertex angle of one side, back to the beam body 1, of the web plate of the end beam head 2, the notch 21 is communicated with the mounting hole 22, the radial opening type structure of the mounting hole 22 is formed, and a fixing hole 23 for fixing the bearing seat 31 is formed in the web plate of the end beam head 2. Namely, after the connecting hole on the bearing seat 31 is butted with the fixing hole 23, the bolt is screwed in to fix the bearing seat 31 on the mounting hole 22, and the travelling wheel 3 is mounted on the bearing seat 31 through a rotating shaft. Because the mounting hole 22 is of a radial opening structure, after the bolt for fixing the bearing seat 31 is loosened, the bearing seat 31 and the road wheel 3 can be moved out of the mounting hole 22 from the radial direction of the mounting hole 22, so that the bearing seat 31 and the road wheel 3 can be conveniently dismounted or maintained.
A baffle 4 used for shielding the walking wheels 3 is arranged at one end of the end beam head 2 back to the beam body 1. This baffle 4 can shelter from breach 21 in the length direction of end beam subassembly, plays the effect of protection.
When the split-type end beam head boring machine is used specifically, because the end beam head 2 and the beam body 1 are of a split-type structure, only the end beam head 2 is operated during boring operation, and the end beam head 2 is fixed on the beam body 1 after boring is completed; in the process: 1. the volume of the end beam head 2 is obviously smaller than the whole volume of the end beam, so that the inventory pressure during boring operation can be obviously reduced, and the production cost is reduced; 2. the end beam head 2 is relatively small in size, so that the convenience of boring is remarkably improved; 3. the end beam head 2 can be mounted on beams 1 of different lengths to form different dimensional specifications.
