The embodiments of the present invention is described further with reference to the accompanying drawings and embodiments:
In the description to the utility model, it is to be understood that indicating position or positional relationship are described as based on attached
Orientation or positional relationship shown in figure, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion
Signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this
The limitation of utility model protection range.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is set
Set ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
For convenience of understanding, the connecting rod 8 in Fig. 1 is indicated with straight line.
One kind being opened flat Obstruct apparatus, including mounting rack 1, the catch mounting base 2 that is fixed on 1 two sides of mounting rack, is fixed on peace
The transmission shaft 3 of 1 middle lower portion and the hydraulic cylinder 4 of the driving rotation of transmission shaft 3 are shelved, is rotatably mounted in catch mounting base 2
There is catch 5,3 one end of transmission shaft is fixed with rotating plate 6, and the 6 plate body of rotating plate vertically covers at 3 periphery of transmission shaft, the both ends point of rotating plate 6
Not Tong Guo U-shaped articulation piece 7 be hinged with connecting rod 8, two connecting rods 8 are hinged with catch 5 respectively, the left side flank upper end of the rotating plate 6
It is located at the unfilled corner 10 that the position above track is equipped with triangle equipped with groove 9, under 5 closed state of catch.It is described U-shaped hinged
Hinging pin shaft is plugged between the two sidewalls of part 7, U-shaped 7 bottom end of articulation piece is equipped with screw hole, the screw hole and set on 8 end of connecting rod
External screw thread be adapted.The groove 9 is arc groove, and the length of the flank equipped with groove 9 is less than 6 another side flank of rotating plate
Length.The hydraulic cylinder 4 drives transmission shaft 3 to rotate by drive link 11, and described 11 one end of drive link is fixed on transmission shaft 3
On axle body, the piston-rod end of the other end and hydraulic cylinder 4 is hinged, and the cylinder barrel end of the hydraulic cylinder 4 is hinged on mounting rack 1.
One end of the drive link 11 is equipped with sleeve, and the sleeve covers the company of the axle body key on 3 axle body of transmission shaft and with transmission shaft 3
It connects.The piston-rod end of the hydraulic cylinder 4 is hinged by U-shaped articulation piece 7 and one end of drive link 11.6 middle part of rotating plate
Equipped with sleeve, the sleeve is covered on 3 axle body of transmission shaft and is keyed with the axle body of transmission shaft 3.Two connecting rods 8 pass through U respectively
Type articulation piece 7 and catch 5 are hinged.
Mining car stopper is more frequent in underground use, in the frequent moving process of car arrester catch, if car arrester
Each hinge point is hinged using common pin shaft, then hinge point failure rate is higher, and the use of U-shaped articulation piece greatly reduces resistance
The failure rate of each hinge point of vehicle device, extends service life, however, its bottom can be to general during rotation for U-shaped articulation piece 7
The rotating plate of logical mining car stopper generates blocking, and then influences the maximum open angle of gear wheel, this will result under opening state
Catch whole height is higher, when lower mine vehicle passes through on chassis, can generate blocking to mine vehicle, influence the logical of vehicle
Row.
In the present invention, when needing to open catch, hydraulic cylinder 4 drives transmission shaft 3 counterclockwise by drive link 11
Rotation, transmission shaft 3 drive rotating plate 6 to rotate counterclockwise, since the left side flank upper end of rotating plate 6 is equipped with groove 9,6 energy of rotating plate
It enough hauls connecting rod 8 and rotates bigger angle, this is because the setting of groove 9 reduces resistance of the rotating plate 6 to U-shaped 7 bottom of articulation piece
It keeping off (as shown in Figure 2), this makes the stroke of connecting rod 8 be increased, and then catch 5 is driven to rotate greater angle, meanwhile, catch 5
On the top when catch 5 is fully opened in catch 5 of unfilled corner 10, under the cooperation of groove 9, unfilled corner 10 is able in area
The whole height of catch 5 in the on-state is effectively reduced in the case where relatively small, so that the lower mine vehicle in chassis obtains
To pass through.
Underground vehicle chassis is no more than 50mm apart from rail level, and when installation, it is high in the on-state that guarantee is opened flat Obstruct apparatus
Rail level is no more than 50mm out, and the various vehicles in underground can pass through, and will not generate blocking to the chassis of any vehicle.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
