Description
Technical field
The ancillary equipment for promoting material to fall in the utility model relates to a plant feed bin is stretched more particularly to one kind is hydraulic
Contracting arch breaking apparatus belongs to material conveying equipment technology field.
Background technique
In modern industrial production, material largely is stored using each plant feed bin.Feed bin is during storing material, material
It is easy occur arch camber in feed bin, material in feed bin is caused not send out normally.For this purpose, in Patent No. 201020109013.X
In patent, a kind of arch breaking apparatus is proposed, will be broken when arch camber can occur in feed bin in this arch breaking apparatus by hydraulic cylinder
Arch sleeve is sent in feed bin, mechanically abolishes arch camber.Although this arch breaking apparatus have it is easy to operate, broken arch power is big
The advantages that, but in actual operation, since arch breaking apparatus will generally tilt installation, horizontal peace may be also wanted in special circumstances
Dress, in this way, material and broken arch in feed bin fill after the broken arch sleeve of arch breaking apparatus is protruded into out of pilot sleeve to feed bin
The self weight of itself is set so that bearing very big downward pressure on broken arch sleeve, this pressure will be born by pilot sleeve, be led
It causes to generate very big active force between broken arch sleeve and pilot sleeve, in this way after broken arch sleeve is deep into feed bin, flexible
During very big frictional force is generated between broken arch sleeve and pilot sleeve, cause broken arch sleeve can not be in pilot sleeve
It is smoothly mobile, it will lead to stuck between the two when serious, be normally carried out broken arch operation can not.To solve this problem, urgently
It needs to develop a kind of new arch breaking apparatus, solves that frictional force existing for aforementioned arch breaking apparatus is big, and broken arch sleeve is easy stuck
Problem in feed bin.
Summary of the invention
The purpose of this utility model is just to provide such a hydraulically extensible arch breaking apparatus, it can effectively solve aforementioned
Frictional resistance existing for arch breaking apparatus is excessive, is easy stuck problem.
Purpose of the utility model is realized as follows: a kind of hydraulically extensible arch breaking apparatus, includes broken arch oil cylinder, broken arch set
Cylinder and pilot sleeve, are welded with guide post on the broken arch oil cylinder casing wall, and the quantity of the guide post is no less than three, described broken
Arch sleeve is sleeved in guide post, and one end is closed with end cap, and the piston rod of the broken arch oil cylinder is connected to the end cap of broken arch sleeve
On, the pilot sleeve is sleeved on broken arch sleeve ends, and the pilot sleeve is circumferentially square close to one end of broken arch sleeve ends
Help sliding device to setting, it is described that help sliding device include to help rolling hole, ball, pressurizing block and puller bolt, it is described help rolling hole be
Circumferentially disposed through-hole on pilot sleeve is mounted therein with the ball, and described help on the outside of rolling hole is welded with pressurizing block,
Hole is threaded in the pressurizing block, the puller bolt will help the ball in rolling hole to hold out against broken by the screw thread of pressurizing block
Encircle the outer surface of sleeve.
Described to help sliding device along pilot sleeve circumferencial direction lower half circumference location arrangements, quantity is no less than three sets.
In the other end of pilot sleeve, there is quantity quantity to be no less than along pilot sleeve circumferencial direction upper semicircumference location arrangements
Two sets are helped sliding device.
The ball is abrasion-proof steel ball.
The ball is abrasion-resistant stee cylindrical body, and the axial axis of the abrasion-resistant stee cylindrical body and the axis of pilot sleeve hang down
Directly.
Sliding device is helped by being arranged on pilot sleeve, converts the force of sliding friction between pilot sleeve and broken arch sleeve
For force of rolling friction, frictional force between the two can be substantially reduced, thus help to prevent broken arch sleeve and pilot sleeve it
Between since frictional force is excessive there is stuck problem, have structure simple, effect is good, the series of advantages such as easy to set up.
Using abrasion-proof steel ball or abrasion-resistant stee cylindrical body as ball, lubricating grease is added helping in rolling hole, by holding out against spiral shell
Bolt holds out against ball in broken arch sleeve outer surface, and ball is easy to roll during broken arch slip expansion, reliable operation, drops effect of rubbing
Fruit is good, while the service life of ball can be improved.
Since the frictional force in arch breaking apparatus telescopic process is mainly appeared on close to broken arch sleeve closed end cap pilot sleeve
The lower half circumference of one end and far from broken arch sleeve closed end cap pilot sleeve one end upper semicircumference position on, thus this two
A corresponding location arrangements help sliding device, it can be made to give full play to the downhill race effect of rubbing that helps, and guarantee broken arch sleeve in the course of work
In it is smooth flexible.
Sliding device is helped in two sets of the corresponding position setting of upper and lower part at the both ends of pilot sleeve or more, can be dispersed
The pressure that each device is born, and improve and help sliding effect.
Detailed description of the invention
Attached drawing show the structure chart of the utility model specific embodiment, and B-B location that wherein Fig. 1 show Fig. 2 cuts open
View, Fig. 2 show the cross-sectional view of the position A--A in Fig. 1.
Specific embodiment
In the present embodiment attached drawing, the meaning of each part sequence number is as follows: 1, broken arch oil cylinder；2, guide post；3, broken arch sleeve；
4, abrasion-proof steel ball；5, puller bolt；6, pressurizing block；7, pilot sleeve；8, bolt is connected；9, piston rod；10, rolling hole is helped.
Four guide posts 2 are welded on the casing wall of broken arch oil cylinder 1, broken arch sleeve 3 is sleeved in guide post, and one end is by sealing
The closing of closed end lid, the piston rod 9 of broken arch oil cylinder are connected on the closed end cap of broken arch sleeve by connecting bolt 8, pilot sleeve 7
Broken arch sleeve ends are sleeved on, pilot sleeve is provided with three sets on the lower half circumference close to one end of broken arch sleeve closed end and helps
Device is slided, three sets are also disposed on the upper semicircumference of the other end of pilot sleeve and helps sliding device, it includes to help rolling that every set, which helps sliding device,
Hole 10, abrasion-proof steel ball 4, the pressurizing block 6 with threaded hole and puller bolt 5, pressurizing block, which is welded on, to be helped at rolling hole, is helped in rolling hole and is added
It is marked with lubricating grease.
The right end of pilot sleeve is mounted on the bulkhead of feed bin in figure when installation, and helps the end at the part of sliding device
In lower half circumference, the other end helps sliding device to be located at top.Before work, puller bolt is tightened, holds out against abrasion-proof steel ball in broken arch
The outer surface of sleeve.When work, broken arch sleeve is moved right into feed bin under the driving of broken arch oil cylinder along pilot sleeve,
At this time in feed bin the pressure of material and the self weight of arch breaking apparatus so that pilot sleeve right end lower part and left end top bear it is non-
Often big active force, these active forces are born by abrasion-proof steel ball.When broken arch sleeve is along pilot sleeve telescopic moving back and forth, will break
Force of sliding friction between arch sleeve and pilot sleeve is converted to force of rolling friction, drops the frictional force in moving process significantly
It is low, broken arch sleeve can be effectively prevented and occur the problems such as stuck in pilot sleeve.
