Abstract
The invention discloses a track type dredger installation structure, which comprises a bin which is internally and vertically provided with a pull rod, a plurality of scraping sheets are arranged horizontally and axially on the pull rod, each scraping sheet is symmetrical relative to an axis of the pull rod, the inner wall of the bin is provided with a limit device which comprises two parallel chuck plates and two parallel bolts, the two chuck plates and the two bolts are vertically arranged, one ends of the two bolts are both in threaded connection with one chuck plate, the other ends of the two bolts are both in fastening connection with the other chuck plate and the bin through nuts, and the pull rod is inserted in a square hold formed by the two chuck plates and the two bolts. In the invention, the pull rod is in contact with the chuck plates and has no more friction generated with the inner wall of the bin, thereby the friction force is reduced and the pull rod is difficult to abrade and can move up and down in a more flexible and labor-saving way; and in addition, the detachable installation structure has reasonable design and is easy to disassemble and maintain.
Description
Technical field
The invention belongs to the mining machinery technical field, particularly a kind of track type dredger installation structure.
Background technology
Feed bin at industry splendid attire materials such as China's electric power, coal, chemical industry, metallurgy, building materials generally all is up big and down small square cone and cone, and a lot of materials have big humidity or stickiness, is prone to stop up feed bin; Therefore dredge generally all is installed in these feed bins, dredge comprises the pull bar of vertical setting, and pull bar is provided with several scraping blades; The pull bar peripheral hardware has spacing snap ring; Snap ring is welded on the built-in fitting that the feed bin inwall is provided with in advance, pull bar when up-and-down movement, whole pull bar direct friction bin wall; Friction force is very big, has strengthened the degree of wear of pull bar; Existing pull bar adopts channel-section steel, and bending resistance is limited, and is not too durable; And because the lateral length of all scraping blades is all equal; Hydraulic power is bigger during startup; Be difficult for to start, and scraping blade when moving down resistance very big, the load of hydraulic efficiency gear is bigger; Power consumption also increases, and has also reduced the service life of parts such as oil cylinder, oil pump, solenoid directional control valve, motor, electronic component virtually.
Summary of the invention
The present invention is in order to solve weak point of the prior art, little, the durable track type dredger installation structure of resistance when a kind of simple in structure, work is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: track type dredger installation structure comprises feed bin; Vertically be provided with pull bar in the feed bin, pull rod shaft is provided with several scraping blades to level, and each scraping blade is all about pull bar axis symmetry; The feed bin inwall is provided with inhibiting device, and said inhibiting device comprises two clamps and two bolts, and two clamps laterally arrange; Two bolts laterally arrange, two clamps and two vertical settings of bolt, and an end of two bolts all is threaded with a clamp; The other end of two bolts all is fastenedly connected through nut with another piece clamp and feed bin, and pull bar is plugged in the square opening of two clamps and two bolt formation.
Said each scraping blade length in the horizontal direction shortens from top to bottom gradually.
The vertical spacing of said adjacent two scraping blades equates that all the line of the termination, the same side of each scraping blade is a straight line.
The cross-sectional plane of said pull bar is the I shape shape.
Adopt technique scheme, the square opening that two clamps and two bolts form is that pull bar moves up and down a track is provided, and wherein a clamp is close to the feed bin inwall; Pull bar just can not produce friction with the feed bin inwall again; Reduce friction, pull bar is not easy to wear, and up-and-down movement is laborsaving more flexibly; And this detouchable mounting structure is reasonable in design, is easier to dismounting and maintenance; Each scraping blade length in the horizontal direction shortens from top to bottom gradually; Not only alleviated the weight of scraping blade; Also be convenient to start, resistance reduces when the mediation operation, and the load of hydraulic efficiency gear reduces; Power consumption reduces, and has prolonged the service life of parts such as oil cylinder, oil pump, solenoid directional control valve, motor, electronic component; The line of the termination, the same side of each scraping blade is a straight line, and several scraping blades form pyramidal structures, good looking appearance, stressed evenly, mediation is effective; The cross-sectional plane of pull bar is the I shape shape, and pull bar uses the road rail steel, and tension intensity high bending performance is good, rigidity is strong, sturdy and durable.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the B-B cutaway view in the middle of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, track type dredger installation structure of the present invention comprises feed bin 1; Vertically be provided with pull bar 2 in the feed bin 1; Pull bar 2 axial levels are provided with several scraping blades 3, and all about the axis symmetry of pull bar 2, each scraping blade 3 length in the horizontal direction shortens each scraping blade 3 from top to bottom gradually; The vertical spacing of adjacent two scraping blades 3 equates that all the line of the termination, the same side of each scraping blade 3 is a straight line.Feed bin 1 inwall is provided with inhibiting device 4, and inhibiting device 4 comprises clamp 5, clamp 6, bolt 7 and bolt 8, and clamp 5 laterally arranges with clamp 6; Bolt 7 laterally arranges with bolt 8, clamp 5 and bolt 7 vertical settings, and the same end of bolt 7 and bolt 8 is threaded with clamp 5; The other end of bolt 7 and bolt 8 all is fastenedly connected through nut 9 and nut 10 with clamp 6 and feed bin 1; Nut 9 is positioned at feed bin 1 outside with nut 10, and pull bar 2 is plugged in the square opening 11 of clamp 5, clamp 6, bolt 7 and bolt 8 formation, two inhibiting device 4 of every pull bar 2 supporting uses; The cross-sectional plane of pull bar 2 is the I shape shape, uses the road rail steel best.
When work is used, pull bar 2 upper ends and Power Drive Unit (hydraulic actuating cylinder) are in transmission connection, when hydraulic actuating cylinder drive pull bar 2 moves along the vertical direction; Pull bar 2 can not horizontal hunting under the restriction of inhibiting device 4; Pull bar 2 only produces friction with clamp 6, and friction force is very little, and the load of hydraulic actuating cylinder also just reduces.The pyramidal structure wide at the top and narrow at the bottom that several scraping blades 3 form and the tapering basically identical of feed bin 1; Like this when hydraulic actuating cylinder drive pull bar 2 moves along the vertical direction; Load less, stressed more evenly, power consumption also reduces; Also no longer overload operations of parts such as oil cylinder, oil pump, solenoid directional control valve, motor, electronic component, increase service life.
