Abstract

The invention relates to a mechanical lift mechanism, specifically to a lift type comprehensive monitoring mechanism belonging to the technical field of mechanical automation. The lift type comprehensive monitoring mechanism comprises a housing supporting frame, wherein a transmission mechanism and a pulley rope-winding mechanism; a safety protection device and a basket are fixed to the base plate of the housing supporting frame; the transmission mechanism is composed of a motor and a speed reducer, the two of which are integrated with each other; a drum is mounted on the output shaft of the speed reducer; the drum rotates so that a low temperature resistant communication cable is wound around the drum; the cable is connected with the basket via an upper limiting protection mechanism along the guide pulley rope-winding mechanism; and various sensors are mounted on the basket. The lift type comprehensive monitoring mechanism is capable of accomplishing the following functions of: 1, controlling the lifting thereof by means of a single chip program; 2, automatically measuring the height of the coal level in a silo; and 3, automatically and accurately detecting parameters such as related gas concentration, temperature and the like in a specific position.

Description

Lift comprehensive monitoring mechanism

Technical field

Patent of the present invention relates to a kind of mechanical elevating mechanism, is specifically related to a kind of lift comprehensive monitoring mechanism, and this mechanism can realize the real-time monitoring in the closed silo body, and can freely control through mcu programming, genus mechanical automation technical field.

Technical background

Recently, along with industrial expansion, various large-scale closed warehouses also occur thereupon; Particularly each is large-scale with the storage of coal enterprise and coal production industry coal and the storage of silo grain; Make that the safety monitoring of large-scale closed warehouse is more and more important, owing to large-scale warehouse generally all is the tall and big and basically relatively sealing of warehouse, so the comprehensive monitoring of various potential safety hazards has just become big problem in the warehouse; Because various potential safety hazards are different in the closed warehouse; Need various monitoring equipment of number and various opertaing device in context of detection, the installation and maintenance difficulty is big, and Comprehensive Control monitoring operation waits all complicated.

Summary of the invention

The purpose of patent of the present invention is for solving the weak point of above-mentioned prior art; A kind of lift comprehensive monitoring mechanism is provided; It includes the housing supports framework; Be fixed with mechanism of twisting rope on the housing supports framework, mechanism of twisting rope includes gear train and pulley wiring mechanism, is fixed with safety guard and hanging basket on the lower shoe of housing supports framework; Described gear train is made up of motor and speed reducer; Motor is fixed on the housing supports framework; Reductor is fixed on the motor; The output shaft of asynchronous machine is connected through the main drive shaft of gear and reductor, on the output shaft of reductor cylinder is housed, and the cylinder rotation is wrapped in low temperature resistant soft communication cable on the cylinder; Described safety guard includes the upper limit protection mechanism; Described hanging basket is square brandreth, and its top is provided with suspension ring, and communication cable is wrapped on the cylinder in the housing supports framework, is connected with hanging basket through the upper limit protection mechanism along leading block wiring mechanism; This device has realized that not only its number is various, that function is different monitoring equipment installs monitoring concentratedly; And can make various sensors touch the surface, coal seam, and effectively improved the accuracy of real time data in the warehouse, reduced opertaing device quantity; And can also pass through mcu programming; Installation and maintenance are convenient in convenient, flexible control, have better solved the potential safety hazard problems that comprehensive monitoring runs in the warehouse.

The employing motor-driven is convenient and swift, and reductor itself has the function of braking again, automatically locks after the outage; The employing Single-chip Controlling is accurate, and is simple, flexibly; Simple and practical, the on-the-spot installation, operation, easy to maintenance; Through mcu programming control, can realize single action, functions such as interlock, self-detection, fault diagnosis, operating mistake warning, safe shutdown; The rising or falling speed of this device can be regulated; Mechanism adopts the box frame structure, is applicable to that the suspension of various closed warehouse monitoring systems is regulated, and also can be used as in the occasion of general assignments such as loading, unloading, lifting; Rising or falling speed 20～30m/min, lifting weight 10kg.

Description of drawings

Accompanying drawing is the version figure of lift comprehensive monitoring mechanism.

1. support frame; 2. gear train; 3. cylinder; 4. connector; 5. wiring mechanism.; 6. optoelectronic switch; 7. microswitch; 8. limiting plate; 9. sensor; 10. hanging basket; 11. tilt switch.

Embodiment

Lift comprehensive monitoring mechanism can control through joystick on the spot, also can on long-range host computer, control; Manually control is fairly simple, and the control personnel determine the rotating and the operation of motor according to the situation of observing and stop; In the time of on host computer, be to be connected with the single chip communication module through configuration software; Row is just being transported in the energising of SCM program control motor, drives the cylinder forward rotation and discharges cable, and hanging basket moves downward, and nylon roller can lead for cable; Main shaft rotates a circle, makes promptly produce what switching signals of counting by optoelectronic switch break-make how many times, can calculate the height that cable descends; Through the correlation formula position height of producing coal that can convert; When tilt switch is run into the material surface, can produce a switching signal, motor stops operating, and detecting sensor is carried out gas, temperature, the isoparametric collection of smog, and data arrive host computer through the communication cable synchronous transmission; Stop after 10 seconds, the counter-rotating of SCM program control motor, cable drives upwards operation of hanging basket; When moving to upper limit, can touch switching signal of microswitch generation motor is stopped operating, under Single-chip Controlling; After several seconds, motor several circles that reverse again stop then.
