Abstract

The invention relates to a hinged type plane combined locking sealing mechanism. The hinged type plane combined locking sealing mechanism comprises a box body, a rear door, an oil cylinder, a push-pull rod assembly and a lock hook. Rear door hinge bases and an oil cylinder base are fixedly connected to the box body. The rear door is connected to the rear door hinge bases. A sealing strip is arranged between the combined faces of the rear door and the box body. The oil cylinder is hinged to the oil cylinder base through an oil cylinder shaft. A hydraulic push rod of the oil cylinder is connected with the lock hook through the push-pull rod assembly. A lock hook locking base is arranged at the bottom of the rear door. Arc transitional guiding grooves are arranged on the rear door hinge bases. The rear door is connected into the guiding grooves through a first hinge shaft in a sliding manner. The arc transitional guiding grooves are adopted on the rear door hinge bases so that the rear door can be attached to the box body into a whole in a plane combined manner when approaching the box body, it is ensured that the combined faces are sealed reliably, no gas, liquid or solid waste leakage appears, and the problem that the combined faces leak due to the fact that a sealing strip is pressed unevenly for a long time, ultra-deformation and overload fatigue are caused is solved.

Specific embodiment

As shown in figure 1, this lock sealing mechanism is mainly by box-like body, the latch hook mechanism of 7, two synchronizations in back door, oil cylinder 8th, two back door hinge seats 3, sealing device and power transmission link gear etc. are constituted.

Back door 7 is passed through back door hinge seat 3 and is connected with casing body formation radial type, and back door hinge seat 3 adopts curved transition Gathering sill, guiding back door 7 when close to box-like body can in the way of plane engagement with casing adhesion integral it is ensured that combine Face seal is reliable, occurs without air-liquid and solid waste seepage, back door 7 and box-like body are with the purpose of plane engagement mode Be exactly emphasis solve the uneven for a long time pressurized and super deformed amount of sealing strip 6, over loading fatigue damage and cause faying face seepage.

As shown in figure 4, the sealing strip that the sealing mechanism of back door 7 and box-like body is just built-in on the groove of back door 7 passes through Impressed pressure effect just sticks to tank surface, and on sealing strip 6, the raised sill formula structure in three roads reduces the mistake of seepage gas and water Effect probability.

The load transfer device of locking is to exert a force by oil cylinder 8 to be transferred to latch hook 17 to push-pull bar assembly 11, in locating shaft 13 Carry out positioning both vertically as well as horizontally under effect, and the elongation with oil cylinder 8, latch hook 17 is progressively by tight level compacting sealing strip 6 Play sealing function.

Two symmetrical back door hinge seats 3 are vertically welded in the plane of box-like body, and back door hinge seat 3 is welded on On back door, the shape of the gathering sill of curved transition is the positioning track being made up of two sections of straight lines and easement curve.

Oil cylinder 8 one end carries out activity installation, the other end and push-pull bar assembly by the oil cylinder seat 1 being welded on box-like body 11 are connected, and promote push-pull bar assembly 11 during oil cylinder elongation.Form certain moment of torsion and force lock in the presence of push-pull bar assembly 11 Hook rotary shaft 16 is moved, and the linear motion of oil cylinder 8 so becomes the rotary motion of latch hook rotary shaft 16, latch hook rotary shaft 16 Supported by the outer pole socket 14 of four latch hooks, latch hook rotary shaft 16 band moveable lock hook 17 rotates together, the positioning edge on latch hook 17 Locating shaft 13 and haul back door 7 according to profile track lower end and rotate, simultaneously in the gathering sill of two curved transition Move along targeting part in the lower upper end of effect, the top and bottom at back door 7 are respectively under the comprehensive function according to two sets of detent mechanisms Form the motion in level of approximation direction, the sealing strip 6 on back door is equably pressurized in the presence of rear door frame 18 to be fitted in casing On body, thus reaching obturation effect.

As shown in Fig. 2 described back door hinge seat 3 includes two, two described back door hinge seats 3 are symmetrically fixedly connected on case On body body.

As shown in figure 1, being fixedly connected with push-pull bar hinge seat 9 on described back door 7, described push-pull bar hinge seat is provided with waist Shape hole gathering sill, slidably connects second hinge axle 10 in mounting hole gathering sill, the hydraulic thrust rod end of described oil cylinder 8 is hinged described Second hinge axle 10, hinged push-pull bar assembly 11 simultaneously on second hinge axle 10.

Further, box-like body bottom is provided with locating shaft 13, and on back door 7, the position of corresponding described locating shaft 13 is provided with lock Tight guide lugs 12.

Further, the bottom at described back door 7 is fixedly connected with the outer pole socket 14 of at least two latch hooks, on the outer pole socket 14 of latch hook It is rotatably connected to latch hook rotary shaft 16, hinged latch hook 17 in latch hook rotary shaft 16.

Further, in order to ensure the intensity of back door hinge seat 3, described back door hinge seat 3 is provided with reinforcement.

α, β angle in Fig. 3 directly affects back door and shifts efficiency and the uniformity entering position, most important to sealing effectiveness, and one As for, select α ＞ β, herein α be 36 °；β is 30 °.Calculate transition arc after α, β angle determines.
