Specific embodiment
The present invention is illustrated below according to attached drawing illustrated embodiment.This time disclosed embodiment can consider in all sides
Face is to illustrate, without limitation.The scope of the present invention is not illustrated to be limited by following implementation, only by claims
Shown in range.
A kind of dipper crowding gear of the present embodiment is applied during truss oil filling riser closed loading.The purlin that embodiment is related to
The main structure of frame oil filling riser includes: gas-liquid split-phase threeway 4, liquid-phase tube 5 and flexible nanubrium (including outer tube 6 and inner tube 7).Wherein
Gas-liquid split-phase threeway 4 is multi-stage expansion pipe for recycling residual air, liquid-phase tube 5.Outer tube 6 is fixed on the outside of gas-liquid split-phase threeway 4
On flange.Inner tube 7 is sleeved on inside outer tube 6, and is coaxially disposed, and can be slided up and down along the inner wall of outer tube 6, the connection of 7 lower end of inner tube
Sealing cover 16, inner tube 7 can drive sealing cover 16 to move up and down.The material of sealing cover 16 is media-resistant rubber, with tank car tank mouth
Contact.
The lower end of outer tube 6 is arranged in dipper crowding gear, positioned at the top of sealing cover 16.Dipper crowding gear includes driving device 8, pressure
Power device, clamp device and telescopic device 15.Driving device 8 is connected with pressure apparatus, and clamp device is connected with telescopic device 15,
Pressure apparatus is located at the outside of clamp device.Pressure apparatus can move up and down relative to clamp device, and clamp device can be along interior
The outer surface of pipe 7 moves up and down.
Wherein, driving device 8 is used to the up and down motion of driving pressure device, can be using cylinder or oil cylinder etc..This implementation
In example, attachment base 9 is equipped on the outer wall of 6 lower part of outer tube, driving device 8 is fixed on attachment base 9.
Pressure apparatus is used to provide pushing force, i.e., the pressure for inwardly fastening the thrust of inner tube and inner tube being driven to move downward,
A kind of integrated briquette structure can be specifically used, it can also be using as shown in Figure 1 by pressing plate 10, briquetting set 11 and briquetting 12
The separate structure of composition, wherein pressing plate 10 is sleeved on the outside of inner tube 6, and connect with the output rod of driving device 8, briquetting 12
It is fixed on 11 inside of briquetting set, briquetting set 11 is fixed together with pressing plate 10.
Clamp device can include fastener ball 13 and support sleeve 14, support using separate structure shown in Fig. 1
Set 14 is sleeved on 11 inside of briquetting set, can opposite fortune between support sleeve 14 and briquetting set 11, inner tube 7 positioned at the outside of inner tube 7
It is dynamic, in the aperture or groove that ball 13 is mounted on support sleeve 14 and it can roll.Ball 13 is arranged multiple and along inner tube 7
Even circumferential distribution, accordingly, pressure apparatus is also provided with multiple.Clamp device can also be using whole garter spring form, directly
It is set in the outside of inner tube 7, is not provided with support sleeve 14.It is needed on contact surface when both pressure apparatus and clamp device squeeze
One inclined-plane is set, and the form of another contact surface does not limit, can be T-type skewback, sphere, cylindrical body, triangle body etc.,
As long as clamp device is made to have stress towards the direction of inner tube 7.The present embodiment sets the contact surface of briquetting 12 to
Inclined-plane, the fastener of clamp device is using sphere or the ball 13 of cylindrical body.
Telescopic device 15 is located at the lower section of clamp device, mainly includes spring and spiral shell for adjusting the height of clamp device
Bar, naturally it is also possible to similar effect, telescopically adjustable structure can be reached using other, such as tension spring, torsional spring, rubber elastomer
Deng.One end of the present embodiment screw rod passes through the hole on 14 flange of support sleeve and connect with briquetting set 11, and the other end is equipped with step.Spring
Lower end be pressed on the step of screw rod, the upper end of spring is pressed on the lower end surface of support sleeve 14, and spring is with the step of screw rod lower end
Face is that support presses upwards on support sleeve 14, and the pressing force of spring is greater than the sum of the gravity of support sleeve 14 and ball 13.
The following detailed description of the course of work of the present embodiment dipper crowding gear:
In the initial state, as shown in Figure 1, inner tube 7 is retracted to inside outer tube 6, driving device 8 does not work, and stretches out stroke
It is zero, the upper surface (i.e. in Fig. 1 at A) of support sleeve 14 is bonded with the lower end surface (i.e. in Fig. 1 at B) of outer tube 6, support sleeve 14 and outer
Pipe 6 is relatively fixed, and spring force cannot push support sleeve 14 to move upwards, without active force between the inclined-plane and ball 13 of briquetting 12,
There is gap in the outer surface of ball 13 and inner tube 7, guarantees that internal and external casing movement is smooth, when inner tube 7 is moved downwardly to seal cover board 16
When with tank car mouth upper contact, inner tube 7 is no longer moved downward.Driving device 8 is opened in next step, as shown in Fig. 2, driving device 8
Extension bar move downward, the pressure apparatus for pushing pressing plate 10, briquetting set 11 and briquetting 12 to form, pressure apparatus moves downward,
Since the pressing force of the spring of telescopic device 15 is greater than the gravity of clamp device, support sleeve 14 under the action of the spring in the short time not under
Drop.With moving downward for pressure apparatus, screw rod is also moved downward, spring elongation, pressure release, but also requires to guarantee after discharging
The pressure of spring is greater than the sum of the gravity of support sleeve 14 and ball 13, and the inclined-plane of briquetting 12 is contacted with ball 13 and 13 edge of ball
Radial inward movement, after ball 13 and the contact of inner tube 7, the downward pressing force of briquetting 12 passes through inclined-plane and generates the level point increased
Tight inner tube 7 is forced, the frictional force that pressing force generates is greater than the lower pressure of driving device 8, so dipper crowding gear is non-slip, driving dress
It sets 8 pressure to be transmitted to by dipper crowding gear on the sealing cover 16 of inner tube 7 and lower end connection, the rubber pad of 16 lower part of sealing cover
Compress closed tank truck mouth.
After the completion of entrucking, the extension bar of driving device 8 is withdrawn upwards, and extension bar drives pressure apparatus to move upwards, this
When briquetting set 10 and 12 uplink of briquetting, the inclined-plane of briquetting 12 to ball 13 without pressing force, but because support sleeve 14 lower end by
The pressure of the spring of telescopic device 15 acts on, and ball 13 but only rolls in ball hole without departing from the inclined-plane and inner tube 7 of briquetting 12
Rise, does not influence the movement of inner tube 7.When driving device 8 continues up, the upper surface (i.e. in Fig. 1 at A) of support sleeve 14 with
The lower end surface (i.e. in Fig. 1 at B) of outer tube 6 is bonded, and support sleeve 14 and outer tube 6 are relatively fixed, and spring force cannot push support sleeve 14
It moving upwards, pressure apparatus will also continue up, and the inclined-plane of briquetting 12 (can not contact) with ball 13 without active force at this time,
There is gap in the outer surface of ball 7 and inner tube 7, and driving device 8, which continues up stroke, to be terminated, and inner tube 7 drives sealing cover 16
Rising is recovered to inside outer tube 6, completes truss oil filling riser closed loading process.
