Abstract
A hydraulic control retractable type handpiece pad frame for a scraper conveyer is convenient and reliable to operate and achieves stepless lifting within a certain range, and comprises an upper pad frame body, a lower pad frame body, a jack, a one-way lock and an operating valve bank, wherein the upper pad frame body and the lower pad frame body are of U-shaped box structures, the jack is fixed to the lower pad frame body, the upper pad frame body is retractably installed in the lower pad frame body, the upper pad frame body is connected with the lower pad frame body through the jack, and the one-way valve and the operating valve bank which are used for controlling the jack to act are both fixed on the lower pad frame body.
Description
Technical field
The utility model relates to a kind of device that is used for support scratch board conveyer head.
Background technology
Slat conveyer is a kind ofly to using flexible body as the continuous action formula Transport Machinery of trailer coupling, is the chief component of mine transportation device.The head that forms scrapper conveyor after scrapper conveyor headstock and driving device assembling is placed on head poppet, generally, whole scrapper conveyor is laid on driving surface, and scrapper conveyor head is placed in gate road, head poppet height is fixed, and is used for supporting head and moves ahead with the passing that realizes head.In particular cases, because driving surface and gate road have height fall, conventional head poppet just can not practical requirement.
Summary of the invention
The utility model object is for overcoming the deficiency of above-mentioned prior art, the telescopic head poppet of hydraulic control for slat conveyer that stepless heightening in a kind of convenient and reliable operation, certain limit is provided, transport plane is operated steadily.
The utility model comprises poppet, lower poppet, jack, one-way lock and operating valve set; Upper poppet and lower poppet are all U-shaped body structures, and this structure not only has very strong tension compressive property, and has very strong torsional property, and globality is strong, good stability, and intensity is high, not yielding; Jack is fixed on lower poppet, and upper poppet is contained in lower poppet with interior flexible pattern, by jack and lower poppet, be connected, and by the height of poppet in the extension and contraction control of jack, thus the attitude of adjustment transport plane head and fuselage.One-way lock and operating valve set are all fixed on lower poppet, work to control jack.Jack stroke 320mm, thrust 385kN, pulling force 186kN, meets operating needs.
The utility model head poppet adjustable stroke 320mm, poppet minimum altitude 715mm, maximum height 1035mm, bottom-to-top-height can be between 715mm and 1035mm step-less adjustment, so that scrapper conveyor in progradation, is realized transport plane head and fuselage remains best operation attitude.The operation and maintenance of hydraulic efficiency pressure system have enough survival spaces, simple and convenient operation and maintenance.
The utility model is simple in structure, easy to operate, take hydraulic pressure as power, and pulling force is powerful, operates steadily, and strong adaptability, safety are good.When the drop of crossheading base plate and working plate changes, by hydraulic control system, regulate the stroke of heightening jack, control and carry head and fuselage in perpendicular, to remain best operation attitude.When being applicable to coal mine fully-mechanized mining working and gate road and having drop to change, support and regulate the attitude of head and the fuselage of scraping transporter, realize smooth and easy operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, lower poppet, 2, upper poppet, 3, jack, 4, one-way lock, 5, operating valve set.
The specific embodiment
Upper poppet 2 and lower poppet 1 are all U-shaped body structures, jack 3 is fixed on lower poppet 1, upper poppet 2 is contained in lower poppet 1 with interior flexible pattern, and upper poppet 2 is connected by jack 3 and lower poppet 1, and one-way lock 4 and the operating valve set 5 of controlling jack 3 effects are all fixed on lower poppet 1.
Scrapper conveyor head is placed on poppet 2, propelling along with driving surface, drop between driving surface and gate road changes, being used for the height of the telescopic head poppet of hydraulic control of support scratch board machine head just needs to regulate, the piston rod that manipulation valve group 5 is controlled jack 3 stretches, lower poppet 1 and cylinder body are motionless, and upper poppet 2 and scrapper conveyor head just move up and down along with the flexible of jack 3 piston rods, to adapt to the drop of floor undulation and gate road base plate, change.Jack 3 stretches to suitable height, makes Scraper Conveyor in Mining Face head and fuselage in vertical plane, remain optimum posture, guarantees the smooth and easy operation of conveyer.
