Description
Technical field
The utility model belongs to lifting machine accessory applied technical field, is specifically related to a kind of quick rotation stop device for lifting machine steel rope.
Background technology
Lifting machine refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, belong to material carrying machine, the work characteristics of lifting machine does intermittent exercise, namely in a working cycle, the corresponding mechanism of the action such as feeding, migration, unloading is alternation, its development commercially and use more and more extensive.But lifting machine brings efficiently in enterprise production process, simultaneously easily and efficiently, because of the safety hazard of machinery, again and again have an accident, cause heavy economic losses, major embodiment when power control unit breaks down, the steel rope hanging thing drops rapidly, and then has an accident.
Based on the problems referred to above, the utility model provides a kind of quick rotation stop device for lifting machine steel rope.
Utility model content
Utility model object: the purpose of this utility model is for the deficiencies in the prior art, a kind of quick rotation stop device for lifting machine steel rope is provided, solve existing traditional lifting machine and design irrational problem without rotation stop device or rotation stop device, improve lifting machine working security, stop the generation of falling accident.
Technical scheme: a kind of quick rotation stop device for lifting machine steel rope, is made up of positioning support structure and spline structure; Described positioning support structure comprises case, and be arranged on the first connecting arm, second connecting arm at case two ends, and be arranged on the first case baffle plate, the second case baffle plate that the first connecting arm, the second connecting arm are connected with case respectively, and be separately positioned on base, the guide pipe of case both sides, and be arranged on the first axis hole on the first connecting arm, the second connecting arm; Described spline structure comprises spline storehouse, and is positioned at spline core and the spline steel ball in spline storehouse; Described spline structure is arranged in positioning support structure by the second axis hole on spline core and the first shaft hole matching.
Further described base is set to L-type.
The contact surface of further described spline storehouse, spline core and spline steel ball is set to uneven sliding surface.
Further described spline steel ball is set to irregular cycle.
Compared with prior art, the beneficial effect of a kind of quick rotation stop device for lifting machine steel rope of the present utility model is: 1, the positioning support structure of appropriate design, installs firm, stable, withstand voltage, wear-resisting long service life; 2, spline core and the spline steel ball in spline storehouse is positioned at, when there is fall failure, rough instantaneously by stuck for irregular cycle spline steel ball, thus stop the trend continuing tenesmus, use under normal circumstances and namely at the uniform velocity carry out lifting action, spline steel ball can there will not be stuck phenomenon by return in time.Simultaneously low, the structure of the utility model productive costs simply, is easily promoted.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
A kind of quick rotation stop device for lifting machine steel rope as shown in Figure 1, Figure 2 and Figure 4, is made up of positioning support structure and spline structure; Positioning support structure comprises case 1, and be arranged on first connecting arm 2, second connecting arm 3 at case 1 two ends, and be arranged on the first case baffle plate 4, second case baffle plate 5 that the first connecting arm 2, second connecting arm 3 is connected with case 1 respectively, and be separately positioned on base 6, the guide pipe 7 of case 1 both sides, and be arranged on the first axis hole 8 on the first connecting arm 2, second connecting arm 3; Spline structure comprises spline storehouse 9, and is positioned at spline core 10 and the spline steel ball 11 in spline storehouse 9; Spline structure to be coordinated with the first axis hole 8 by the second axis hole 12 on spline core 10 and is arranged in positioning support structure.
Preferred further, base 6 is set to L-type as shown in figure 3, installation, convenient disassembly, and it is firm to locate; Spline storehouse 9 as shown in Figure 5, spline core 10 are set to uneven sliding surface with the contact surface of spline steel ball 11, and spline steel ball 11 is set to irregular cycle, increase friction force.
Embodiment
Further as shown in Figure 1, Figure 4 and Figure 5, spline structure is arranged in positioning support structure by the first axis hole 8 and the second axis hole 12, if routine travels at the uniform speed spline storehouse 9, the relatively stable action of spline core 10 during use, energy return rapidly after now spline steel ball 11 transfer certain distance, thus there will not be stuck phenomenon, ensure normal lifting operation, if namely accelerate soon by spline storehouse 9, spline core 10 relative rotation speed for steel rope lapse rate, can not return rapidly after now spline steel ball 11 transfer certain distance, there is stuck phenomenon (complete and stop tenesmus action); This is rotation stop device fast, reasonable integral structure, and long service life, working stability are applied widely.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
