Abstract
The invention discloses a hydraulic pushing type locking device. The hydraulic pushing type locking device comprises a support and a locking mechanism arranged on the support. The locking mechanism comprises a cylinder barrel and a locking shaft, wherein the cylinder barrel is horizontally fixed to the support, the locking shaft is arranged in the cylinder barrel, and the two ends of the locking shaft extend out of a baffle ring in a left opening of the cylinder barrel and a baffle ring in a right opening of the cylinder barrel in a sealing and sliding mode respectively. The middle of the locking shaft is of a circular platform structure which is in sliding fit with the inner wall of the cylinder barrel in a sealing mode. An inner cavity of the cylinder barrel is divided into a left cavity chamber and a right cavity chamber through a circular platform, and the parts, located on the left cavity chamber and the right cavity chamber, of the cylinder barrel wall are respectively provided with a hydraulic liquid port communicated with an outside pump station. The hydraulic pushing type locking device has the advantages of being simple and compact in structure, convenient to operate and short in stroke, the overall size of the locking device is effectively reduced, a gate pier does not need to be thickened, engineering investment is reduced, and the hydraulic pushing type locking device has a good sight effect. Meanwhile, the hydraulic drive is adopted, and therefore the hydraulic pushing type locking device can be applied to the overwater engineering and undwater engineering.
Description
Technical field
The present invention relates to flap gate locking device, especially relate to hydraulic pressure pushing-type locking device.
Background technology
Along with the continuous quickening of social progress and urbanization process, urban ecology water system engineering also develops rapidly as important symbol and the important component part of Modern Water Conservancy thereupon, and flap gate is widely used in this type of engineering.The lock mode of flap gate routine adopts locking apparatus for motor push rod more, due to locking apparatus for motor push rod size large (single locking device length is in 1.5m left and right), in order to meet the layout of locking device, require the middle pier thickness of porous lock in 3m left and right, the thickness of abutment pier also need be in 2m left and right, and this has not only strengthened investment but also has affected attractive in appearance.Therefore, adopting a kind of flexible operation, characteristics of compact layout, the little locking device that takes up room, is the emphasis of Metal Structure Design in this type of engineering.
Summary of the invention
The object of the invention is to provide a kind of hydraulic pressure pushing-type locking device.
For achieving the above object, the present invention takes following technical proposals:
Hydraulic pressure pushing-type locking device of the present invention, comprises bearing, is arranged on the locking mechanism on described bearing; Described locking mechanism comprises the cylinder barrel being horizontally fixed on bearing, is arranged on the lock shaft in described cylinder barrel, and described lock shaft two ends seal respectively to slide extends outside the baffle ring of the left and right nozzle of cylinder barrel; Lock shaft middle part is for to seal with inner wall of cylinder the frustum cone structure being slidably matched, and inner cavity of cylinder is divided into left chamber and right chamber by described round platform; Be positioned on the cylinder barrel wall of described left and right chamber and offer respectively the hydraulic fluid mouth for being communicated with extraneous pumping plant.
The left and right riser that described bearing is connected thereon by base plate and interval forms; Described cylinder barrel is fixed between described left and right riser; Described lock shaft two ends respectively with the plate hole matched in clearance of left and right riser; In the plate hole of described right riser, be inlaid with axle sleeve, described axle sleeve right side is provided with pressure ring, and described pressure ring is fixedly connected with right riser by bolt.
The invention has the advantages that simple and compact for structurely, easy to operate, stroke is short, has effectively reduced the overall dimensions of locking device, without the thickness that strengthens gate pier, has not only reduced construction investment but also have good landscape effect.Meanwhile, the present invention, owing to adopting hydraulic-driven, therefore can be applicable to waterborne also can be applicable under water.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, hydraulic pressure pushing-type locking device of the present invention, comprises bearing, is arranged on the locking mechanism on described bearing; The left and right riser 2,3 that described bearing is connected thereon by base plate 1 and interval forms; Described locking mechanism comprises the cylinder barrel 4 being horizontally fixed between described left and right riser 2,3, be arranged on the lock shaft 5 in described cylinder barrel 4, described lock shaft 5 two ends seal respectively slip and extend outside the baffle ring 6,7 of cylinder barrel 4 left and right nozzles and in the plate hole matched in clearance of left and right riser 2,3; Lock shaft 5 middle parts are round platform 8 structures that are slidably matched with cylinder barrel 4 inner wall sealings, and cylinder barrel 4 inner chambers are divided into left chamber 9 and right chamber 10 by described round platform 8; Be positioned on cylinder barrel 4 walls of described left and right chamber 9,10 and offer respectively the hydraulic fluid mouth 11,12 for being communicated with extraneous pumping plant.For ease of installing, in the plate hole of right riser 3, be inlaid with axle sleeve 13, described axle sleeve 13 right sides are provided with pressure ring 14, and described pressure ring 14 is fixedly connected with right riser 3 by bolt.
When the present invention locks, input high pressure liquid by extraneous pumping plant to the right chamber 10 of cylinder barrel 4, drive lock shaft 5 left parts to stretch out by the right side of promotion lock shaft 5 middle part round platforms 8 flap gate 15 is locked.When release, input high pressure liquid by extraneous pumping plant to the left chamber 9 of cylinder barrel 4, drive lock shaft 5 left parts retractions that flap gate 15 is untied by promoting the left side of lock shaft 5 middle part round platforms 8.
