Description
Technical field
Crane hoisting mechanism technical field is the utility model is related to, especially a kind of crane being connected with trolley frame rises
Rise the fixed structure of pulley beam.
Background technology
Crane is used for harbour handling workpiece, is the important production equipment of shipyard, its principal organ is lifting mechanism and fortune
Row mechanism.At present, the fixed block beam in lifting mechanism is generally integrally welded with trolley frame, turns into a kind of redundant structure,
Because the force analysis of pulley beam is indefinite, deformation is also complex, past in structure in order to ensure the strength and stiffness of pulley beam
Rich toward comparison is all designed to, so whole vehicle frame just seems more heavy, and bulky body frame structure for automotive not only makes lifting trolley certainly
It is many to weigh small car weight substantially more other than external ad eundem, and rolled steel dosage is big, and cost is high, poor safety performance.
The pulley beam fixed structure of prior art is heavy, and dolly load is big, poor safety performance, and manufacturing cost is high.
Utility model content
A kind of crane hoisting pulley beam that the purpose of this utility model is in view of the shortcomings of the prior art and designed is consolidated
Determine structure, the bolt fastening structure of channel-section steel is fixed using pulley beam both ends, pulley beam is arranged on shearing branching beam supporting construction small
On vehicle frame, the weight of beam in itself is alleviated, so that trolley frame structure also becomes simpler, light and handy, the installation of pulley beam, dismounting
All very convenient, it is very big convenient to be brought for maintaining, meanwhile, increased cushion pad can reduce vibration, reduce noise, increase
The comfort level of operating personnel.
What the purpose of this utility model was realized in：A kind of fixed structure of crane hoisting pulley beam, including set
Pulley beam on trolley frame, it is characterized in that the end carriage of trolley frame is provided with built-in channel-section steel, pulley beam both ends are provided with clamp screw
The locating notch of bolt, for pulley beam with shearing branching beam structure setting on the end carriage of trolley frame, its built-in channel-section steel is sleeved on locating slot
It is intraoral, and pulley beam is fixedly installed on the end carriage of trolley frame by tight fixed bolt；The built-in channel-section steel is welding with end carriage；
The locating notch is provided with the nut and through hole welded with it；The tight fixed bolt screws in through hole by nut and withstands built-in groove
Steel, pulley beam is fixedly installed on the end carriage of trolley frame with shearing branching beam structure.
Cushion pad is provided between the locating notch and built-in channel-section steel.
The utility model has trolley frame simple in construction, light and handy compared with prior art, the installation of pulley beam, dismantles more
It is convenient, pulley beam is arranged in the form of shearing branching beam on trolley frame by the built-in fixed channel-section steel at both ends, make beam body stress
Clearly, the deficiency and shortcoming of fixed block Installation Modes in existing monkey are preferably improved, not only reduces steel
Dosage, the weight of beam is alleviated, reduce cost, and security performance is more preferable, reduces vibrations, reduces noise, increases operator
The comfort level of member.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is Fig. 1 top views；
Fig. 3 is that pulley beam is fixedly connected with schematic diagram with end carriage.
Embodiment
Refering to 1~accompanying drawing of accompanying drawing 2, the utility model is made up of the end carriage 8 of pulley beam 1 and trolley frame, the pulley beam 1 with
For shearing branching beam structure setting on the end carriage 8 of trolley frame, its corresponding built-in channel-section steel 2 being welded on two end carriages 8 is sleeved on positioning
In notch 7, and built-in channel-section steel 2 is withstood by tight fixed bolt 4, pulley beam 1 be fixedly installed on the supporting construction of shearing branching beam small
On the end carriage 8 of vehicle frame.
Refering to accompanying drawing 3, the both ends of the pulley beam 1 are provided with the locating notch 7 of tight fixed bolt 4, are set on the locating notch 7
There is the nut 5 and through hole 6 welded with it；Cushion pad 3 is provided between the locating notch 7 and built-in channel-section steel 2；The clamp screw
Bolt 4 screws in through hole 6 by nut 5 and withstands built-in channel-section steel 2, and the end carriage 8 of pulley beam 1 and trolley frame is connected to one.
The utility model is such making and installation：The rule of built-in channel-section steel 2 are chosen by the design requirement of locating notch 7
Lattice number, and corresponded to and be welded on two end carriages 8 of trolley frame, it is from top to down when pulley beam 1 is installed on trolley frame
The periphery of built-in channel-section steel 2 is embedded in, contact surface is used as by cushion pad 3, after installation, both ends are logical with tight fixed bolt 4 again
Cross nut 5 and withstand built-in channel-section steel 2, the axial displacement of limitation pulley beam 1.The pulley beam 1 and this installation side of fixed structure
Formula makes beam body stress clear, can more be accurately controlled the strength and stiffness of beam, if the end carriage 8 of trolley frame is because of cause specific
After deformation, can by the position of the built-in channel-section steel 2 of movement come reinstall with fixed block beam 1, after effectively prevent deformation
The potential safety hazard that local buckling leaves, make the installation of pulley beam 1, dismounting more convenient, reduce the cost of maintaining.
Simply the utility model is further described above, and is not used to limit this patent, all is the utility model
Equivalence enforcement, it is intended to be limited solely by within the right of this patent.
