Description
Technical field
A kind of test device for jack ejecting force is the utility model is related to, for detecting the ejecting force of jack.
Background technology
Civil air defense constructions and installations includes the parts such as exterior wall, cushion wall, explosion proof door, enclosing wall, protection partition wall and formed, and is mainly used in the people
Antiaircraft temporary shelters, wartime air defense direction center, communication center, hideaway etc., part permanent defenses also have anti-nuclear weapon
Device, anti-chemical weapon, the three proofings function of anti-biological weapon.Civil air defense constructions and installations is in addition to possessing wartime air defense purposes, in recent years, also often
As all kinds of natural calamity emergency shelters.
The airtight blast door set as protection airtight, it is to prevent contamination air from entering civil air defense constructions and installations through gateway that it, which is acted on,.
Existing people's air defense airtight blast door, all it is the solid sealed door by steel plate and concrete for making, overall heavier, installation
During airtight blast door, because of the limitation in space, typically airtight blast door is jacked up using hand-operated jack, then implement to install.
Installed by the production of closed guard gate for many years, for the service condition of hand-operated jack, it is found that it is present necessarily not
Foot, although marking out its maximum rated ejecting force in jack model, often can not accurately measure its top in actual use
The numerical values recited of output, so as to which damage caused by stress is excessive in jack work easily occur, security incident easily occurs.
Therefore, hand-operated jack to its maximum rated ejecting force before use, first must detect.Conventional detection side
Method is to install strain transducer on the push rod of the big piston of jack, by measuring instrumentss direct measurement pressure, but such a method
Cost is higher.
The content of the invention
In view of the situation of prior art and existing deficiency, the utility model provides a kind of for jack ejecting force
Test device, the device, simple in construction, easy to use, clear reading, stable performance, safe and reliable, cost is low.
To achieve the above object, used technical scheme is the utility model：A kind of survey for jack ejecting force
Trial assembly is put, including draw-bar donamometer, it is characterised in that：Also include pedestal, fixed mount, fixing bolt, top plate, steel wire rope I, steel wire rope
IIth, rectangular slab；
The pedestal, fixed mount and top plate are rectangle, in the both sides of seat surface, fix one piece of fixed mount respectively,
Be spirally connected a fixing bolt respectively in the nut that two pieces of fixed mount upper ends are fixed, and one is set respectively in the front end of two fixing bolts
Block rectangular slab, fixing bolt, two pieces of rectangular slabs being correspondingly arranged in opposite directions or can be moved conversely clockwise or counterclockwise；
The lower end of two draw-bar donamometers, respectively one end with steel cable II fix, the other end of two steel wire ropes II, point
It is not fixed on the seat surface between two pieces of fixed mounts, the upper end of two draw-bar donamometers, one end with steel cable I is consolidated respectively
It is fixed, the other end of two steel wire ropes I, it is separately fixed on the lower surface of top plate.
The beneficial effects of the utility model are：For hand-operated jack before use, by the detection of the device, it is accurate to draw
Ejecting force, so as to learn maximum ejecting force of the hand-operated jack in real work, help we solve machinery production and
In actual mechanical process, the size of accurate control jack ejecting force is led to not because closed guard gate is overweight, and thousand can not be learnt
Can jin pushes up maximum ejecting force bear closed guard gate's pressure, so as to bring potential safety hazard the problem of.The device have it is simple in construction,
The advantages that easy to use, clear reading, stable performance, safe and reliable, low cost, other field can be applied and popularized to.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model.
Embodiment
As shown in figure 1, a kind of test device for jack ejecting force, including draw-bar donamometer 8, in addition to pedestal 1, fixation
Frame 2, fixing bolt 3, top plate 4, steel wire rope I 5, steel wire rope II 6, rectangular slab 7.
Pedestal 1, fixed mount 2 and top plate 4 are rectangle, and in the both sides in the face of pedestal 1, one piece of fixed mount 2 is respectively welded,
Be spirally connected a fixing bolt 3 respectively in the nut 2-1 that two pieces of upper ends of fixed mount 2 are welded and fixed, in the front end of two fixing bolts 3
One piece of rectangular slab 7 is set respectively, fixing bolt 3 clockwise or counterclockwise, two pieces of rectangular slabs 7 being correspondingly arranged can in opposite directions or
It is opposite mobile.
On the lower loop of two draw-bar donamometers 8, one end with steel cable II 6 is fixed respectively, two steel wire ropes II 6
The other end, on the face of pedestal 1 being welded between two pieces of fixed mounts 2 being respectively separated, on the top ring of two draw-bar donamometers 8, respectively
Fix, the other end of two steel wire ropes I 5, be respectively welded on the lower surface of top plate 4 with one end of steel cable I 5.
Draw-bar donamometer 8 is 10T two-way tension tables.The basic parameter of draw-bar donamometer is as follows：
1st, draw-bar donamometer accuracy class is 2.0.
2nd, draw-bar donamometer measurement range is 0-120KN.
3rd, the sensitivity of draw-bar donamometer is less than or equal to the 0.5% of full scale load.
4th, the overload capacity of draw-bar donamometer is that load exceeds maximum measured value 50%.
Application method, as shown in Fig. 2 step is as follows：
The lower end of jack 9 is arranged on to the centre position in the face of pedestal 1, the upper end of jack 9 is arranged on the lower surface of top plate 4
Centre position.
Turn clockwise two fixing bolts 3, moves towards the rectangular slab 7 that two front ends of fixing bolt 3 are set, until
Contacted with the two sides of the lower end of jack 9, jack 9 is firmly positioned on the face of pedestal 1.
Hand-operated jack rocking bar, very heavy top collet is increased and contacted with the lower surface of top plate 4, continue hand-operated jack rocking bar,
Until very heavy top collet rises to limiting altitude, now, on the top plate 4, top plate 4 changes into drawing for the ejecting force effect of jack 9
Power, and by two steel wire ropes I 5 and the opposing force of two steel wire ropes II 6, pull two draw-bar donamometers 8, make two draw-bar donamometers 8 same
When show pulling force data, according to the reading data of two draw-bar donamometers 8, the ejection force value of jack 9 can be drawn.
The effect of top plate 4 is that the active force for making jack 9 is uniformly distributed, and the pulling force of the draw-bar donamometer 8 of both sides is kept balance.
