Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of compact conformation is provided, stroke is adjustable, spacing accurately, the travel control device of stable drive, operating maintenance is convenient, defencive function is perfect, degree of automation is high steel wire rope winch.
The objective of the invention is to realize by following technical scheme:
The travel control device of steel wire rope winch, it is characterized in that: the trip control setup comprises control capsule and is installed in control capsule interior gear journey controller, miniature gears axle and guide pin bushing axle, described control capsule is fixed on the built-in drop-gear box housing of roller, the gear journey controller is installed in the control capsule, the guide pin bushing axle by bearing installation on control capsule; The gear end of miniature gears axle is meshed with the gear cluster of gear journey controller, and the other end of miniature gears axle inserts the inner of guide pin bushing axle and utilizes finger setting; The outer end of guide pin bushing axle is made as square toes, and these square toes insert in the square hole sleeve of the built-in reducing gear axle of roller afterbody.
As a further improvement on the present invention, secondary limit position protection switch is installed on the described roller, tightens up at steel rope, emit when exceeding the limit travel that secondary limit position protection switch is provided with, secondary limit position protection switch control motor reducer auto-stop; The forced stroke that the limit travel that this secondary limit position protection switch is provided with is provided with greater than the gear journey controller.
As a further improvement on the present invention, the load limiter of being made up of resistance-strain type load transducer and electric controller is equipped with in the end of described steel rope, under the overload situation, and electric controller control motor reducer auto-stop.
Compared with the prior art the present invention has the following advantages:
(1), the gear journey controller of on the built-in reducing gear axle of roller, packing into, make that forced stroke is spacing accurately, stroke is adjustable; And structure is airtight, cuts off with abominable factor such as external environment, makes internal mechanism be subjected to favorable protection.
(2), original limit switch changes secondary limit position protection switch on the roller, has secondary position limitation protection function.
(3), load limiter is housed, have overload protection function at steel cord ends, when mechanism's overload, can automatic shutdown protection.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a travel control device amplification view of the present invention.
Description of reference numerals: 1-motor reducer, 2-roller, the built-in reducing gear axle of 3-roller, 4-gear journey controller, 5-miniature gears axle, 6-guide pin bushing axle, 7-control capsule, the built-in drop-gear box housing of 8-roller, 9-secondary limit position protection switch, 10-load limiter, 11-steel rope, 12-bearing.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, the output shaft of motor reducer 1 links to each other with the input shaft of the built-in drop-gear box of roller, is used for driving roller 2 and rotates.The present invention is installed on the built-in drop-gear box housing 8 of roller, the present invention mainly is made up of control capsule 7 and the gear journey controller 4, miniature gears axle 5 and the guide pin bushing axles 6 that are installed in the control capsule 7, control capsule 7 utilizes screw retention on the built-in drop-gear box housing 8 of roller, gear journey controller 4 utilizes screw to be installed in the control capsule 7, and guide pin bushing axle 6 is installed on the control capsule 7 by bearing 12; The gear end of miniature gears axle 5 is meshed with the gear cluster of gear journey controller 4, and the other end of miniature gears axle 5 inserts the inner of guide pin bushing axle 6 and utilizes finger setting; The outer end of guide pin bushing axle 6 is made as square toes, and these square toes insert in the square hole sleeve of built-in reducing gear axle 3 afterbodys of roller.
As shown in Figure 1, secondary limit position protection switch 9 is installed on the described roller, this secondary limit position protection switch 9 has replaced the original limit switch in both sides, roller 2 top; When the forced stroke of gear journey controller 4 spacing when malfunctioning, steel rope 11 on the winch roller 2 is still in action, tighten up, emit when exceeding the limit travel that secondary limit position protection switch 9 is provided with at steel rope 11, secondary limit position protection switch 9 is controlled motor reducers 1 auto-stop, thereby reaches the purpose of secondary position limitation protection; The forced stroke that the limit travel that this secondary limit position protection switch 9 is provided with is provided with greater than gear journey controller 4.
As shown in Figure 1; the load limiter of being made up of resistance-strain type load transducer and electric controller 10 is equipped with in the end of described steel rope 11; under the overload situation; resistance-strain type load transducer on the load limiter 10 senses the load change situation and transmission signals is given electric controller; electric controller is controlled motor reducer 1 auto-stop, reaches the purpose of safety guard-safeguard.
Principle of work of the present invention and working process are as follows:
During steel wire rope winch work, in the stroke that gear journey controller 4 is set, motor reducer 1 regular event drives the steel rope 11 that is wrapped on the roller 2 and tightens up, emits; Roller 2 drives the built-in reducing gear axle 3 of roller and rotates when rotating; built-in reducing gear axle 3 of roller and then drive guide pin bushing axle 6 and miniature gears axle 5 rotate; the gear cluster engaged transmission of miniature gears axle 5 and gear journey controller 4; 4 work of gear journey controller; after through the forced stroke that is provided with; gear journey controller 4 control motor reducers 1 auto-stop promptly arrives the travel position that sets and stops.
The present invention can conveniently realize centralized control or automatic guidance, can be widely used in industries such as electric power, machinery, petrochemical industry, metallurgy, traffic, coal, environmental protection.
