Description
Technical field
The utility model relates to the Novel positioning structure of a kind of telescopic machine tail and pushing beam, the use that the drag conveyor telescopic machine tail being applicable to colliery pit mining work plane is connected with tail pushing beam.
Background technology
Colliery pit mining Scraper Conveyor in Mining Face telescopic machine tail limits due to self structure, and tail pushing beam that cannot be supporting with it is made of one, and which results in the problem existing between telescopic machine tail with tail pushing beam and how to be connected location.Because telescopic machine tail and pushing beam self individuality are comparatively large, heavier-weight, exists and not easily installs in the actual use procedure in down-hole, to dress difficulty, connector frequent breakage ruptures, and pushing beam cannot pass use, connecting bolt is anti-rotation not, and after nut loosening, bolt easily rotates and comes off, and does not have connection function.These problems usually cause work plane to run well, and have had a strong impact on operating efficiency and productivity ratio.
Such as telescopic machine tail is in the past connected with pushing beam and adopts the connected mode of T-shape bolt+alignment pin directly pushing beam and telescopic machine tail to be linked together, this kind of connected mode is in actual use first to dress difficulty, pushing beam both sides are welded with 2 alignment pins and telescopic machine tail in advance and install and locate, underground working condition is limited, and pushing beam and the larger weight of telescopic machine tail self individuality weigh, bearing pin fit clearance is little again, to pretending when difficulty, especially alignment pin in use after stress deformation to dress especially not easily; Secondly this kind of connected mode bonding strength is not high, actual use in pushing beam often and telescopic machine tail come off, mining face under mine is always uneven, in passing process, alignment pin vertical direction is not by spacing, torsion and shearing force act directly on T-shape bolt up and down, after repeatedly passing, the nut loosening on T-shape bolt, deviates from not have connection function and causes pushing beam to come off from telescopic machine tail from bolt block after T-shape bolt 90-degree rotation.
Utility model content
The purpose of this utility model be to provide a kind of structure simple, install easily, bonding strength is high, the Novel positioning structure of the reliable telescopic machine tail of firm position and pushing beam, can realize the telescopic machine tail of coal mine work high-yield and high-efficiency and the location of pushing beam.
The Novel positioning structure of a kind of telescopic machine tail and pushing beam, comprise telescopic machine tail and pushing beam, its special feature is: be welded with a pin annular groove positioning pressuring plate separately in described pushing beam both sides, each pin annular groove positioning pressuring plate all has the guiding annular groove coordinated with telescopic machine tail junction, and each pin annular groove positioning pressuring plate is all removably connected by securing member and telescopic machine tail in addition.
Wherein on each pin annular groove positioning pressuring plate, be equipped with shear pin, thus passing shearing force can be born to increase the bonding strength of pin annular groove positioning pressuring plate.
Wherein securing member adopts the T-shaped bolt with anti-turning pad.
Connection in the utility model location structure between telescopic machine tail and pushing beam adopts pin annular groove positioning pressuring plate, and this positioning pressuring plate contact area is large, and bonding strength is high, is furnished with shear pin and guiding annular groove simultaneously.Shear pin bears passing shearing force, increases the bonding strength of location-plate, and the effect of the guiding existing spacing location of annular groove has again the effect of guiding installation, and make tail and pushing beam install easily, after installing, position is relatively fixing, not easily play.Add anti-turning pad in the T-shaped bolt that this external telescopic machine tail is connected with pushing beam, even if bolt and nut is loosening to some extent like this, T-shaped bolt also cannot rotate, and can not deviate from from bolt block, has effectively played the linkage function of bolt.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is using state schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, 2, the utility model provides the Novel positioning structure of a kind of telescopic machine tail and pushing beam, comprise telescopic machine tail 1 and pushing beam 2, a pin annular groove positioning pressuring plate 3 is welded with separately in described pushing beam 2 both sides, each pin annular groove positioning pressuring plate 3 all has the guiding annular groove coordinated with telescopic machine tail 1 junction, and each pin annular groove positioning pressuring plate 3 is all removably connected by securing member and telescopic machine tail 1 in addition.
Wherein on each pin annular groove positioning pressuring plate 3, be equipped with shear pin, thus can bear passing shearing force to increase the bonding strength of pin annular groove positioning pressuring plate 3, securing member adopts the T-shaped bolt with anti-turning pad in addition.
Using method of the present utility model and operating principle are:
The utility model devises pin annular groove positioning pressuring plate 3 in pushing beam 2 both sides, the pin annular groove positioning pressuring plate 3 of side is welded on pushing beam 2 securely, the pin annular groove positioning pressuring plate 3 of opposite side is designed to the demountable structure of T-shaped bolt+anti-turning pad connection, when installing in down-hole, only telescopic machine tail 1 need be advanced along dismountable pin annular groove positioning pressuring plate 3 side by the direction of guiding annular groove, efficient and convenient to filling.Pin annular groove positioning pressuring plate 3 contact area is large simultaneously, and bonding strength is high, positioning pressuring plate is furnished with shear pin and guiding annular groove.Shear pin bears passing shearing force, increase the bonding strength of location-plate, the effect of the guiding existing spacing location of annular groove has again the effect of guiding installation, after installing, position is relatively fixing, not easily play, even if run into the work plane that down-hole rises and falls, the pin annular groove positioning pressuring plate 3 that pushing beam 2 side is firmly welded effectively limits telescopic machine tail about 1 play, and telescopic machine tail 1 cannot be deviate from from guiding annular groove.
Anti-turning pad is added in the T-shaped bolt that this external telescopic machine tail 1 is connected with pushing beam 2, even if bolt and nut is loosening to some extent like this, anti-turning pad also can stop T-shaped bolt to rotate in bolt block, T-shaped like this bolt would not be deviate from from bolt block, effectively play the linkage function of bolt, add the reliability of connection.The utility model efficiently solve down-hole telescopic machine tail 1 and pushing beam 2 to fill and pushing beam 2 in use procedure often from the problem that telescopic machine tail 1 comes off.
