Abstract
A plough-type electric discharger for fuel coal is composed of machine frame, discharging plough, four-connecting-rod lifting driver, and angle-variable center-regulating roller set, and features that under the control of four-connecting-rod lifting driver, the discharging plough can move up and down smoothly and the slot angle of conveying belt can change to a plane while the plough moves up and down, so it can fully contact with discharging plough to discharge all the ful coal by scraping. Its advantages include convenient application, high stability and plough lifting flexibly.
Description
The present invention relates to a kind of power plant coal load transfer device, the parallel four-bar two side electric plough type unloading apparatus of specifically a kind of belt-type coal conveyor discharging midway belongs to electrical equipment technical field.
Firepower electrical plant is to adopt belt plow as coal blending equipment the fire coal on the band conveyor to be assigned in run coal bin or the silo mixed coal jar mostly at present, from the existing condition of service of the discharger of installation and operation power plant's Coal Blending System, new installation is all right in the initial operating stage effect, but the accident that colter isolates the belt of band conveyor just often appears after a period of time in operation, influenced the normal ordinary production that goes up coal and power plant of coal bunker, also increase maintainer's labour intensity, increased the productive costs of power plant.The inventor discloses a kind of name and has been called " variable groove angle six connecting rod belt plows " in No. 952334879 patent of China.This kind discharger has had bigger improvement with more original discharger on technical performance, but also has some unsatisfactory places on structure design, as aspects such as stable aspect, alerting ability aspect and reliability.
The purpose of this invention is to provide a kind of stability, alerting ability, reliability etc. bigger improved parallel four-bar two side electric plough type unloading apparatus is arranged.
The objective of the invention is to realize in the following manner, be used as power with the electric pushrod actuator, promote the parallel four connecting rod lifting mechanism work that the colter both sides are connected with the electric pushrod actuator, drive the vertical steadily lifting of colter, and maintenance and band conveyor contact well fire coal scraped from the belt conveyor of band conveyor and are assigned to the coal bunker.
Accompanying drawing 1 is the structural representation of facing of parallel four-bar two side electric plough type unloading apparatus;
Accompanying drawing 2 is the plan structure scheme drawing of parallel four-bar two side electric plough type unloading apparatus;
Accompanying drawing 3 is the left end TV structure scheme drawing of parallel four-bar two side electric plough type unloading apparatus.
With reference to Figure of description to the structure of parallel four-bar two side electric plough type unloading apparatus of the present invention do with Under explain.
Parallel four-bar two side electric plough type unloading apparatus of the present invention, its structure are by frame 1, discharging Colter 2, four connecting rod lifting drivers, alterable trough aligning carrier roller group 3 consist of, by four connecting rods The coordination control discharging colter 2 steady oscilaltions of lifting driver are on discharging colter 2 The lifting of control alterable trough aligning carrier roller group 3 changes the groove angle of conveyer belt 16 in the time of lower lifting Realize that conveyer belt 16 is the plane and with discharging colter 2 good contacts fire coal is scraped and unloaded totally.
Four connecting rod lifting actuators are by electric pushrod actuator 4, buffering pull bar 5, adjusting yoke 6, commutation support link 7, colter support link 8, last horizontal support connecting rod 9, following horizontal support connecting rod 10, driving lever 11, interlock hinge axis 12, short frame hinge axis 13, lead aircraft frame hinge axis 14 is formed, electric pushrod actuator 4 is fixed on the top of frame 1 by hinge frame 15, the right-hand member of the left end of electric pushrod actuator 4 and buffering pull bar 5 joins with the upper end of commutation support link 7, the left end of buffering pull bar 5 and the right-hand member of adjusting yoke 6 are attempted by the centre of interlock hinge axis 12, and the left part of adjusting yoke 6 joins fixing by the front portion of hinge and discharging colter 2.
The lower end of commutation support link 7 joins with the centre of short frame hinge axis 13, the two ends and the frame 1 of short frame hinge axis 13 are joined, the two ends of the upper end of the left end of last horizontal support connecting rod 9 and colter support link 8 and interlock hinge axis 12 also connect, the right-hand member of last horizontal support connecting rod 9 joins with the two ends of short frame hinge axis 13, and the left end of horizontal support connecting rod 10 was connected together by hinge and discharging colter rear portion under the lower end of colter support link 8 reached.
The two ends of lead aircraft frame hinge axis 14 are fixed by bearing and frame 1, the middle part of the right-hand member of last horizontal support connecting rod 9 and lead aircraft frame hinge axis 14 joins fixing, the two ends of the upper end of driving lever 11 and lead aircraft frame hinge axis 14 join fixing, and the lower end of driving lever 11 and variable groove angle aligning carrier roller group 3 are joined.
Embodiment:
Parallel four-bar two side electric plough type unloading apparatus of the present invention, installation and processing gets final product shown in the by specification accompanying drawing.The electric pushrod actuator is the commercial approved product, and other each parts can be processed into by conventional machinework and welding process.
The working process of parallel four-bar two side electric plough type unloading apparatus of the present invention is such: fire coal is carried to each blending bunker by belt conveyor, the coal inlet of blending bunker is located at the below of belt conveyor, parallel four-bar two side electric plough type unloading apparatus is installed in the top of coal blending Hatch Opening, colter is positioned at the top of belt conveyor, when blending bunker lacks coal, electric pushrod drives and is put into colter on the belt conveyor reposefully with colter bonded assembly four connecting rods, the chevron pointing colter scrapes the fire coal on the belt conveyor in the blending bunker, after the blending bunker coal blending finishes, collaborative four lever linkages of electric pushrod steadily lift the discharging colter, fire coal on the belt conveyor just is transported to next coal blending Hatch Opening and by next parallel four-bar two side electric plough type unloading apparatus fire coal is unloaded, and the like finish the coal blending operation of blending bunker.The effect of variable groove angle aligning carrier roller group is to send when being with when the discharging colter drops to ship, driving lever is stirred variable groove angle aligning carrier roller group and is contacted with the discharging colter from the belt conveyor below with belt conveyor picking-up formation plane, unloads totally so that the discharging colter is scraped the fire coal on the belt conveyor.Coal blending finishes, and when the discharging colter upwards lifted, it was to make belt conveyor return to original defeated coaly attitude that variable groove angle aligning carrier roller group falls.
Parallel four-bar two side electric plough type unloading apparatus of the present invention is compared with existing technology, and has design Rationally, the characteristics such as easy to use, good stability, failure rate is low, colter lifting be flexible, thereby, Have good value for applications.
