Abstract

The invention discloses an engine-driven grinding tail rope controller. The engine-driven grinding tail rope controller comprises two bases installed on a same bearing, two ratchet wheels and a grinding barrel, wherein the two bases are installed at the two ends of the bearing and are connected and fixed through a transverse bar, the two ratchet wheels are fixed to the two sides of the grinding barrel respectively, the bearing is sleeved with the grinding barrel, the ratchet wheels are driven to circumferentially rotate along with the bearing, ratchet pawls are fixed to the two ends of the transverse bar respectively, and therefore the ratchet wheels and the ratchet pawls are fixed in the same plane. The ratchet pawls form a torsion spring structure through the heads of the ratchet pawls and the tails of the ratchet pawls, when grinding rope paying off is performed and rotating speed is low, the heads of the ratchet pawls are slowly knocked by ratchet teeth, when the speed of the grinding barrel is increased, namely grinding deviation happens, due to the fact that the heads of the ratchet pawls are knocked with larger force by the ratchet teeth, tension force of a spring is overcome, the tails of the ratchet pawls are clamped into the ratchet wheels, and the locking purpose is achieved. The engine-driven grinding tail rope controller can effectively avoid the grinding deviation risks caused when braking loses efficacy, and potential hazards of accidents are reduced.

Description

Motor-driven grinding mill tail rope controller

Technical field

The present invention relates to a kind of motor-driven grinding mill tail rope controller, belong to strand mill technical field.

Background technology

Motor-driven grinding mill is as the high weight-lifting equipment of frequency of utilization in transmission and transformation engineering construction, play indispensable vital function, strand mill comprises diesel engine or spark ignition engine, reductor and mill tube, mill tube is driven by diesel engine or spark ignition engine and reductor, wirerope-winding is on mill tube, strand mill is by load and manpower tense wire rope, makes to produce friction force between steel rope and core grinding, then by mechanical drive, core grinding is rotated.In the drag process of strand mill, once brake was lost efficacy, just have the risk of running mill.The operating mode that strand mill runs mill mainly contains two kinds, a kind ofly runs mill while being rope closing, and another is while putting rope, to run mill.

Summary of the invention

In order to solve the defect existing in prior art, the invention provides a kind of motor-driven grinding mill tail rope controller, while braking inefficacy for solving, the situation of running mill under two kinds of common operating modes.

For achieving the above object, the technical solution used in the present invention is:

Motor-driven grinding mill tail rope controller, comprise two pedestals that are arranged on same bearing, two ratchets and mill tube, described two pedestals are arranged on the two ends of bearing, and be connected and fixed by cross bar, described two ratchets are individually fixed in the both sides of mill tube, described mill tube is sleeved on bearing, and drive ratchet with bearing circular-rotation, the two ends of described cross bar are all fixed with ratchet pawl, described ratchet pawl forms torsion spring structure by ratchet pawl head and ratchet pawl afterbody, the ratchet of described both sides and ratchet pawl are all in same plane, in rotation process, ratchet pawl head can touch hook tooth.

Aforesaid pedestal is triangular base.

Aforesaid cross bar has 3.

The hook tooth direction of aforesaid two ratchets is consistent.

The two ends of aforesaid cross bar are equipped with outside thread, by nut, ratchet pawl are fixed between pedestal and mill tube.

Angular range between aforesaid ratchet pawl head and ratchet pawl afterbody is 90 ° ~ 150 °.

By adopting technique scheme, the present invention can solve the race mill risk existing when brake was lost efficacy effectively, has reduced accident potential, also without increasing new power, just can realize the control to tail rope simultaneously, has reduced the input of manpower and physics.

Accompanying drawing explanation

Fig. 1 is the structural representation of motor-driven grinding mill tail rope controller of the present invention.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.

Strand mill when strand mill brake timeliness runs grinder condition and mainly contains two kinds, a kind ofly runs mill while being rope closing, and another is while putting rope, to run mill.

During for rope closing, run mill, can partly install a ratchet additional at mill tube output shaft, prevent that friction lining in rope closing process lost efficacy and the race mill that causes, in rope closing process, ratchet pawl is always along with ratchet clatter clatter campaign, and when mill tube counter motion, ratchet pawl blocks ratchet and reaches the object that prevents from running mill.Because ratchet can only when strand mill is when putting rope form state, need to all be opened ratchet and just can put rop exercise work towards a direction stop, if run mill under this operating mode, this escapement cannot play the effect that prevents from running mill.

For putting when rope, run mill, the invention provides motor-driven grinding mill tail rope controller as shown in Figure 1, for the ease of checking structure and the position relationship of ratchet and ratchet pawl, Fig. 1 of the present invention regards pedestal as transparent when mapping, to demonstrate ratchet and the ratchet pawl of mill tube both sides.

As shown in Figure 1, the present invention includes two triangular base 1 that are arranged on same bearing, two ratchets 6 and mill tube 7, wherein, two triangular base 1 are arranged on the two ends of bearing, and are connected and fixed by three cross bars 5, and three cross bars 5 are positioned on three angles of pedestal, in use procedure, pedestal 1 is fixed by anchoring device and ground; Two ratchets 6 are one-way wheel, and hook tooth 2 directions are consistent, and two ratchets 6 are individually fixed in the both sides of mill tube 7, and mill tube 7 is sleeved on bearing, and drive ratchet 6 with bearing circular-rotation; The two ends of three cross bars 5 are equipped with outside thread, by nut, ratchet pawl is fixed between pedestal 1 and mill tube 7, make ratchet 6 and ratchet pawl in same plane, described ratchet pawl forms torsion spring structure by ratchet pawl head 3 and ratchet pawl afterbody 4, angular range between ratchet pawl head 3 and ratchet pawl afterbody 4 is 90 ° ~ 150 °, guarantees in rotation process, and ratchet pawl head 3 beats hook tooth 2, when running mill, ratchet pawl afterbody 4 can snap in hook tooth 2.

When strand mill is put rope, mill rope slowly moves forward, drive mill tube and ratchet to rotate, when velocity of rotation is little, hook tooth slowly knocks ratchet pawl head, now, ratchet pawl afterbody also cannot snap in ratchet, and not stop, when mill tube speed is accelerated to run mill, the strength of knocking ratchet pawl head due to hook tooth becomes large, and the pulling force that overcomes spring causes ratchet pawl afterbody to snap in the object that ratchet reaches stop.

The present invention is illustrated according to the preferred embodiment, is to be understood that above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the form of equivalent transformation obtains, within all dropping on protection scope of the present invention.
