Abstract
The utility model discloses a two-way manual picture peg door has solved the current long yielding of stroke of cutting or auto-change over device, has opened and close hard, the more problem that produces the potential safety hazard easily of the part that stretches out outward. The hand wheel fixing device comprises a plug board, a hand wheel, a fixing support and the like, and is characterized in that a nut is welded on the bottom surface of the plug board, and a screw rod is arranged to be sleeved on the nut and connected with the hand wheel through a bearing. The utility model discloses easy maintenance, safety, convenience, flexibility, the picture peg is opened easily, can extensively be used for cutting or switching of various hopper or pipeline, especially is used for the raw coal fill.
Description
Technical field:
The utility model relates to a kind of equipment of hopper material conveying process, relates to a kind of insertion plate door that blocks or switch the hopper convey materials or rather.
Background technology:
In the solid material process of conveying powdered, granular, block or its mixture, the putty phenomenon happens occasionally, particularly carry often to run into the sticking coal of coal breakage bucket, paulin coal, chute blockage in the raw coal process, therefore need block, with convenient maintenance to logistics at thermal powerplant.
Existing that existing cutting device has is unidirectional, stroke length is yielding, open and close the drawback of requiring great effort, leakage being arranged again, the partial devices that has is in service protruding more, be easy to generate potential safety hazard, gap between the rail groove that has is bigger, because ature of coal is thin, have sticking foreign material etc. in the coal, be bonded in the rail groove, cause coal to put up a bridge, itself produces the chute blockage phenomenon.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art a kind of two-way manual insertion plate door that hopper or pipeline block or switch, compact conformation, dependable performance of being used for is provided.
The technical solution adopted in the utility model is as follows: comprise plate, handwheel, fixed support etc., it is characterized in that at nut of plate bottom surface welding, screw rod is set is enclosed within on the nut and by bearing and connects handwheel.
Described plate, handwheel, nut, screw rod respectively are two.
Described bearing is a surface bearing.
As shown from the above technical solution, rotation hand wheel, the rotation by screw rod drives the plate turnover, and handwheel, screw rod itself are also unshift, has avoided handwheel, screw rod protruding; The surface bearing that is provided with make handwheel rotation light, flexible, therefore, the utility model is easy to maintenance, safe ready, plate is opened easily, and up and down between the coal spout gap little, after opening, coal, chute blockage can be do not glued, blocking or switching of various hoppers or pipeline can be widely used in, especially for former coal bunker.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a birds-eye view of the present utility model.
Among the figure, 1. handwheel, 2. locating plate, 3. bearing, 4. bolt, 5. screw rod, 6. plate, 7. nut, 8. fixed support, 9. coal spout, 10. pulley.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, left-right symmetric, the plate 6 of setting, handwheel 1, nut 7, screw rod 5 respectively are two.
Described plate 6 is than the big 20-50cm of radius of coal spout 9, and welded nut 7 below plate 6.One end of screw rod 5 is enclosed within the nut 7, and the other end connects handwheels 1 by bearing 3, and promptly handwheel 1 has handwheel sleeve and directly is enclosed within on the screw rod 5.Described bearing 3 is a surface bearing.
Fixed support 8 is the channel-section steel material, and two locatings plate 2 respectively are set on its both sides, and is fixing with bolt 4, is convenient to install bearing 3.In case stop up, can unload bolt 4, take out bearing 3, keep in repair, clear up.
As shown in Figure 2, the utility model also is provided with 4-6 pulley 10 on each limit of fixed support 8, is convenient to plate 6 and slides.
Like this,, can make plate 6 advance or go out easily, expose or stifled go up coal spout 9, and can not make handwheel 1, screw rod 5 protruding by rotation hand wheel 1.
