Description
Technical field
The utility model is related to electromagnetic lifter lifting mechanism equipment field, especially a kind of electromagnetic lifter equalizer bar dress
It puts.
Background technology
Current conventional use of electromagnetic lifter wire tensioner main function is fixed, adjusting hoist rope, due to
Product, there are larger gap, causes its discontinuity equalization in use, screw rod plasticity often occurs with live practical application
The problems such as deformation, bending, fracture, narrow adjusting difficulty and space for maintenance, there are larger security risks, add cost,
Influence crane service efficiency.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of safety coefficient is reliable, ensure crane safety fortune
Row reduces fault handling time, improves the electromagnetic lifter balance boom device of work efficiency.
Technical solution is used by the utility model solves its technical problem：Electromagnetic lifter balances boom device, including
Equalizer bar, to be rotatably connected between the equalizer bar and connecting plate, the connecting plate is fixedly installed on frame, the balance
Beam both ends are both provided with steel cable termina.
It is further that the steel cable termina is wire rope wedge form joint.
It is further that the tie point of the equalizer bar and connecting plate is located at equalizer bar stage casing.
It is further that the equalizer bar is rotatably connected by axis pin and connecting plate.
It is further that described connecting plate one end is rotatably connected with equalizer bar, and the other end is fixedly connected with frame.
The beneficial effects of the utility model are：The utility model cleverly substitutes original rigging using lever construction form
Screw-button, so as to ensure that steel wire rope stress is consistent by the automatic principle of compensation of lever.In actual use, when equalizer bar one
During the pulling force increase that the steel wire rope at end is subject to, equalizer bar can deflect immediately, so as to compensate above-mentioned deflection in real time, together
When, steel wire rope is also prevented because the risk of breakage that pulling force is excessive and occurs.The utility model optimizes topology layout, cancels spiral shell
Spinner is adjusted using equalizer bar, is fixed rope end using wedge joint, is changed to the frame form of gate, increases upright post basic height,
Convenient for checking, replacing, overhauling.The utility model is particularly suitable among electromagnetic lifter lifting mechanism.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure mark for：Frame 1, connecting plate 2, equalizer bar 3, steel cable termina 4, axis pin 5.
Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
Electromagnetic lifter balance boom device as shown in Figure 1, including equalizer bar 3, between the equalizer bar 3 and connecting plate 2
To be rotatably connected, the connecting plate 2 is fixedly installed on frame 1, and 3 both ends of equalizer bar are both provided with steel cable termina 4.
In actual use, crane is altogether using four hoist ropes, wherein every two steel wire ropes are fixed on one jointly
On root crossbeam, therefore the utility model uses the structure of equalizer bar 3.In order to ensure to possess good intensity, meet working condition requirement,
With spacious space, facilitate the job contents such as inspection, maintenance, replacement, the preferred Q345B low-carbon alloy steels of making material are as female
Material is made.Generally, in order to which the rotation of equalizer bar 3 is more flexible, can select the equalizer bar 3 and connecting plate 2
Tie point is located at 3 stage casing of equalizer bar.As shown in Figure 1, the equalizer bar 3 can be rotatably connected by axis pin 5 and connecting plate 2,
So as to it is also ensured that the flexibility rotated.Meanwhile described 2 one end of connecting plate can be selected to be rotatably connected with equalizer bar 3, separately
One end is fixedly connected with frame 1.
In order to which what steel wire rope more fastened is arranged at steel cable termina 4, can select that the steel cable termina 4 is allowed to be steel wire
Rope wedge joint.Due to cover of wedge and the tapered design feature of wedge core carbon steel making may be employed, at heat in the wedge joint
Reason obtains higher strength character, has the performances such as simple in structure, easy to use, reliable and stable, is widely used in all kinds of
Heavy-duty machine.Steel wire rope is fixed between wedge core and cover of wedge, and by the effect of gravity straight down, steel wire rope stationary phase is when fastening, outside
Two steel cable clamps is added to fix rope end, safety coefficient is greatly improved, reduces spare part expense.
The utility model cleverly substitutes original wire tensioner using lever construction form, so as to by lever from
Dynamic Principles of Regulation are consistent to ensure steel wire rope stress.In actual use, when the pulling force that the steel wire rope of equalizer bar one end is subject to increases
When big, equalizer bar can deflect immediately, so as to compensate above-mentioned deflection in real time, meanwhile, steel wire rope is also prevented because drawing
The risk of breakage that power is excessive and occurs.The utility model optimizes topology layout, cancels screw-button, is adjusted, made using equalizer bar
Rope end is fixed with wedge joint, is changed to the frame form of gate, increases upright post basic height, convenient for checking, replacing, overhauling.This
Utility model is particularly suitable among electromagnetic lifter lifting mechanism.
