Abstract
The utility model relates to a hydraulic prop connection clamp for mining; wherein the clip seat is made from two vertical semi circles with different sizes, one end of each semi circle of the clip seat is articulated with a semicircle buckle with the same diameter of the semi circle, a match long groove through hole is provided at the other end of the semicircle buckle and at the opposing end of the clip base against the semi circle and a bolt with a boss at the tail end is put through the long groove through holes to bind the semicircle buckle and the clip base. With the adoption of the structure above, the single-unit hydraulic props can be rigidly integrated by connecting tubes. The connection is fast, reliable, convenient to adjust and to disassemble and reusable, saves the material for the flexible connection and makes the operational site tidy and good-looking.
Description
Technical field:
The utility model relates to a kind of mine individual hydraulic prop Connection Card, is used for connection between the hydraulic prop as a kind of connector.
Background technology:
Hydraulic prop is widely used under the mine, is mainly used in supporting top beam, bears the pressure of the earth.Often several or tens uses together of hydraulic prop in use, also will according to circumstances be adjusted the quantity of use, regulate the distance between the column, dismantle more frequent.Because pressure difference everywhere, hydraulic prop generation deflection is serious, reduces enabling capabilities, has increased unsafe factor.In order to prevent that effectively analogue from taking place, often take interconnective mode, in groups pillar is connected with each other, form a whole, increase the reliability that supports.At present, owing to there is not special-purpose connector, the Field Force often uses iron wire, wire rope etc. to be wrapped on the column when connecting, or makes shroud ring with band iron and be fixed on the column.But because these connected modes are poor, be again soft linking to each other each other, so service behaviour is unreliable, effect is also undesirable, when particularly needing to adjust the pillar position, bothers especially.
Summary of the invention:
The purpose of this utility model provides a kind of mining hydraulic prop Connection Card, can be apace couples together hydraulic prop is rigid each other by them and tube connector, connects fast and reliable, the adjustment easy accessibility.
The purpose of this utility model realizes as follows: a deck is arranged, deck is made of two vertically arranged semicircular ring that vary in size, one end of each semicircular ring of deck hinged with its semicircle clasp with diameter, the semicircle clasp other end is by the other end connection of corresponding semicircular ring on bolt and the deck.Two semicircular ring and semicircle clasp on the deck are formed small one and large one two holes, and macropore and hydraulic prop external diameter are suitable, are used for fixing hydraulic prop, and aperture is used for fixing with tube connector.
There is the plane semicircle clasp and the bolted end of deck semicircular ring, and correspondence is useful on the elongated slot through hole that penetrates bolt on the plane, and the elongated slot through hole passes in the bar portion of bolt, and the bolt upper end is rotary with nut the two is fixed.Adopting the purpose of elongated slot through hole is to be convenient to place the bolt that afterbody has flat boss, and boss is stuck in the elongated slot through hole, prevents when fastening that like this screw rod from rotating, and provides convenience for fastening.
Bolted that end of the semicircular ring of semicircle clasp and deck, at the termination of the two one link bolt, another termination has the elongated slot opening, there is nut the bar portion upper end of bolt, bolt bar portion when unclamping can swing relatively, when this Connection Card is connected with tube connector with hydraulic prop, nut on the bolt is unscrewed and will not screw off by nut, bolt shank can be thrown off from the elongated slot opening, the semicircle clasp can be opened, after buckling into hydraulic prop or tube connector in the deck semicircle, semicircle clasp and deck semicircular ring are buckled together, and enter in the elongated slot opening after the bolt shank swing, screwing nut just can fix, the action that whole process can avoid nut to disassemble from bolt fully, the one, fast, and the 2nd, avoided bolt, falling of nut, lose.
This utility model has following characteristics: (1) is safe and reliable: the column that uses Connection Card to connect is very firm, has effectively prevented the inclination of column, has increased Practical Performance; (2) easy to loading and unloading: use Connection Card to connect, simple to operation, quick, improve work efficiency, reduced labour intensity; (3) save material: since Connection Card be a kind of can reusable connector, therefore reduced cost of production effectively, saved fund; (4) neat and artistic: as to use Connection Card, unified material, unified operation, unified management, positive role is played in civilized construction, civilization scene, standardization construction.
Description of drawings:
Accompanying drawing is the stereogram of the mining hydraulic prop Connection Card of the utility model.
The specific embodiment:
With reference to accompanying drawing, deck 4 is made of two vertically arranged more than half annulus 3 and smaller part annulus 6, one end of deck 4 more than half annulus 3 is by bearing pin 2 hinged and its large semicircle clasps 1 with diameter, one end of smaller part annulus 6 is by bearing pin 2 hinged and its small semicircle clasps 5 with diameter, bearing pin 2 can be bolt, semicircle clasp 1,5 other ends and with deck 4 on the other end of corresponding semicircular ring 3,6 corresponding elongated slot through hole 8 is arranged, the bolt 7 that penetrates tail end band boss in elongated slot through hole 8 connects them.For gaining in strength, there is the reinforcing rib of circumferential and axial deck semicircular ring 3,6 and semicircle clasp 1,5 outsides, their inner surface has axial convex tendon to increase frictional force, the big aperture that deck semicircular ring 3,6 and semicircle clasp 1,5 are formed is respectively applied for fixed hydraulic pillar and tube connector, macropore is used for blocking hydraulic prop, and aperture can block tube connector firmly, presses pillar to link together a discharge opeing by tube connector.
