Abstract
The utility model discloses an improved structure of a sand discharge door of a tank truck tank. The improved structure of the sand discharge door of the tank truck tank comprises a pawl spring device (1), a locking nut (3), a locking arm (5), a ball head screw rod (6) and a gland (8). The pawl spring device (1) is connected to the lower left portion of the locking arm (5), the gland (8) is positioned between two arms of the locking arm (5), the locking nut (3) is installed in the symmetric center line of the locking arm (5), and the ball head screw rod (6) is connected between the locking nut (5) and the gland (8). Due to the structure, force exerted by the outside is evenly distributed on a seal rubber ring through the ball head screw rod, the situation that the seal rubber ring is damaged locally due to uneven stress is avoided, so that a better seal effect is achieved.
Description
Technical field
The utility model relates to the improvement structure of sand discharge door, is specifically related to the improvement structure of tank car tank body sand discharge door.
Background technology
Tank car is the transport vehicle that car body is tank shape, be used for loading and transporting various liquid, liquefied gas and Powdered goods etc., these goods comprise gasoline, crude oil, various viscous oil, vegetable oil, liquefied ammonia, alcohol, water, various acid-base class liquid, cement lead oxide powder etc., tank car occupies very consequence in transit, accounts for 18% of lorry sum.Although the tank car vehicle is a lot, is monocoque structure.The car body of most of tank car all is comprised of tank body and underframe two large parts.The sediment outflow door (hole) of various tank bodies (comprising tank car tank body) generally all adopts a plurality of bolt clip tightening seals, wastes time and energy in the time of keying, can't reach desirable effect, has reduced work efficiency.The fixed form that present sediment outflow door mainly adopts is that bolt is fixed, and this kind fixed form easily occurs causing O-ring seal partial failure because of unbalance stress, thus the desirable sealing effectiveness of out of reach.
The utility model content
The utility model has overcome the deficiencies in the prior art, the improvement structure of tank car tank body sand discharge door is provided, the power that the external world is applied is evenly distributed on the O-ring seal by the bulb leading screw, has avoided because unbalance stress causes O-ring seal partial failure, thereby has reached better sealing effectiveness.
For solving above-mentioned technical matters, the utility model is by the following technical solutions: a kind of improvement structure of tank car tank body sand discharge door, comprise ratchet spring device, jam nut, locking arm, bulb leading screw and gland, described ratchet spring device is connected to the locking arm lower left, described gland is between locking arm two arms, described jam nut is installed on the locking arm symmetrical center line, is connected with the bulb leading screw between described jam nut and the gland.
Further, described jam nut top is connected with moving bar, and moving bar is parallel to locking arm.
Further, be provided with O-ring seal between described ratchet spring device and the gland.
Further, the right arm inside of described locking arm is provided with and slides to down bar and door-hinge, and door-hinge is positioned at the below that slides to down bar.
Further, be provided with gate seat bottom the described gland.
Further, be provided with the center bulb in the middle of the described gland.
Compared with prior art, the beneficial effects of the utility model are:
1, this structure centre bulb is evenly distributed to the power that the external world applies on the O-ring seal of hermatic door by the bulb leading screw, avoided because unbalance stress causes O-ring seal partial failure, thereby reached better sealing effectiveness.
When 2, the utility model has not only reduced the maintenance of various tank bodies the sediment outflow door open and close man-hour, also reduced collating time and the labour intensity of sediment outflow door.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral is expressed as respectively among the figure: 1, ratchet spring device; 2, O-ring seal; 3, jam nut; 4, moving bar; 5, locking wall; 6, bulb leading screw; 7, slide to down bar; 8, gland; 9, door-hinge; 10, gate seat.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated, embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, the utility model comprises ratchet spring device 1, jam nut 3, locking arm 5, bulb leading screw 6 and gland 8.The ratchet spring device 1 of the present embodiment is connected to locking arm 5 lower lefts, is provided with O-ring seal 2 between ratchet spring device 1 and the gland.The gland 8 of the present embodiment is between 5 liang of arms of locking arm, and gland 8 bottoms are provided with gate seat 10, is provided with the center bulb in the middle of the gland 8.The jam nut 3 of the present embodiment is installed on locking arm 5 symmetrical center line, and jam nut 3 tops are connected with moving bar 4, and moving bar 4 is parallel to locking arm 5.Be connected with bulb leading screw 6 between the jam nut 5 of the present embodiment and the gland 8, the right arm inside of locking arm 5 is provided with and slides to down bar 7 and door-hinge 9, and door-hinge 9 is positioned at the below that slides to down bar 7.
When needs are opened the sediment outflow door, rotate moving bar and make the gland unloading, draw and dial the ratchet spring device, the ratchet spring device on the locking arm is decontroled, but just opening encapsulation gland.When needs are closed the sediment outflow door, gland and locking arm are fixed door by ratchet spring device and door-hinge after door-hinge rotates, and rotate moving bar jam nut is compressed gland, and gland is under the effect of bulb leading screw, automatically pressure is evenly distributed to around the gland, makes O-ring seal and gate seat effective sealing.This apparatus structure is simple, and is easy to use.
Just can realize this utility model as mentioned above.
