Structure development machine is widely used in the Tunnel Engineering such as subway, railway, highway, municipal administration, water power.
Hobboing cutter is the critical piece that shield machine carries out soil stone cutting, can frequent and rock structure in operation
Clash into.Be enough to bear certain impact force in order to ensure hobboing cutter, need hobboing cutter is carried out shock-testing,
Being specially is fixed on below impact block by hobboing cutter, then the impact block with the biggest quality is dragged to one
Fixed height, then decontrols impact block and makes its freely falling body collide hobboing cutter cutter ring, if cutter ring is intact, explanation
Hobboing cutter intensity is qualified.
Prior art strikes in order to ensure impact block the appropriate location of hobboing cutter, needs to pass through slider guide
Steadily declining of impact block is realized with coordinating of lead.The when that impact block starting quickly to fall,
Slider guide and lead can produce severe friction, not only produce noise, and cause loss, more important
Be that frictional resistance can cause impact force loss even card, this by affect the accuracy of shock-testing with
Safety.
It is therefore desirable to provide a kind of new testing bench structure to avoid problem above.
Utility model content
Main purpose of the present utility model is to provide a kind of anti-wear shield avoiding guide frame to wear and tear
Machine hobboing cutter shock-testing platform.
This utility model is achieved through the following technical solutions above-mentioned purpose: a kind of anti-wear shield machine roller cutter
Shock-testing platform, including having base, column and the frame of top frame, described top frame hangs down a cable,
Described cable draws a striker, it is characterised in that: it is additionally provided with at least one pair of in described frame vertically solid
Fixed lead, described striker is provided with the slider guide matched respectively with each lead, described
The cross section of lead is I-shaped, and described slider guide is provided with the pulley of pair of parallel pivot joint, two cunnings
Wheel clamps I-shaped middle part.
Concrete, described cable ends is provided with a magnechuck, absorption institute during the energising of described magnechuck
State striker.
Further, described base is provided with and is positioned at the hobboing cutter below described striker and fixes seat.
Further, the bottom of described striker is embedded with impact block.
Further, described top frame is fixed with the traction electric machine for drawing described cable.
Concrete, described pulley is enclosed with plastic washers.
Using technique scheme, technical solutions of the utility model provide the benefit that:
1, pulley can not only reduce equipment attrition, moreover it is possible to reduces mechanical power loss when striker falls,
Ensure the accuracy of shock-testing；
2, striker is released when, between cable and top frame, high-speed resistance not occurring, this just protects
Protect equipment, ensured use safety, extended service life of equipment；
3, traction electric machine can provide the mechanical force promoting striker, makes test more automatization；
4, the independent structure that impact block is set on striker can conveniently be replaced；
5, plastic washers can reduce friction noise.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail.
Embodiment 1:
As depicted in figs. 1 and 2, a kind of shield machine roller cutter shock-testing platform, including having base 11, standing
Post 12 and the frame 1 of top frame 13, the cable 2 hung down from top frame 13 and the electromagnetism being fixed on cable 2 end
Sucker 3；Magnechuck 3 adsorbs a striker 4 when being energized, striker 4 bottom is embedded with impact block 42；
Base 11 is provided with and is positioned at the hobboing cutter below striker 4 and fixes seat 111.Before test prepares, cable 2 is sagging,
Make magnechuck 3 contact impact seat 4；Now magnechuck 3 is energized, electromagnetism under electromagnetic action
Sucker 3 holds striker 4；Then to draw magnechuck 3 the most up for cable 2, makes striker 4 also increase
To certain height；Now shield machine roller cutter 5 is fixed on hobboing cutter to fix on seat 111；Then electromagnetism is inhaled
Dish 3 is stopped power supply, and the striker 4 losing magnetic-adsorption can drop rapidly, makes impact block 42 clash into hobboing cutter 5
By observing hobboing cutter 5, whether outside, the most just can have whether the situation of breakage judges its impact resistance
Qualified.The when of because striker 4 is released, cable 2 moves the most together, therefore cable 2 and top frame
Abrasion at a high speed will not occur between 13, and this just protects equipment, has ensured use safety, extended
Service life of equipment.Impact block 42 is the critical piece clashing into hobboing cutter 5, and therefore rapid wear, impact block 42 sets
Can conveniently replace for the independent structure on striker 4.
As depicted in figs. 1 and 2, top frame 13 is fixed with the traction electric machine 131 for drawing cable 2.Cause
The heaviest for striker 4 component, it is therefore desirable to rely on mechanical force and carry out the lifting of striker 4, so survey
Examination can more automatization.
As shown in Figure 1 to Figure 3, frame 1 is additionally provided with at least one pair of the most fixing lead 14, impact
Seat 4 is provided with the slider guide 41 matched respectively with each lead 14, and slider guide 41 laterally has guide groove
411, lead 14 wall contacts guide groove 411 inner surface.So striker 4 position in the horizontal plane can
To be limited by lead 14, it is ensured that the balance in striker 4 whereabouts, it is to avoid striker 4 drops out machine
Frame 1, it is ensured that clash into and occur in impact block 42 part.
Embodiment 2:
As shown in Figure 4, it is with the difference of embodiment 1: the cross section of lead 14 is I-shaped,
Slider guide 41 is provided with the pulley 412 of pair of parallel pivot joint, and two pulleys 412 clamp I-shaped middle part.
Compared to embodiment 1, pulley 412 can preferably play maintenance punching with coordinating of I-shaped lead 14
Hit the effect of seat 4 balance, and both frictions are sliding friction, can not only reduce equipment attrition, also
Mechanical power loss when striker 4 falls can be reduced, it is ensured that the accuracy of shock-testing.
As shown in Figure 4, pulley 412 is enclosed with plastic washers 4121, so can subtract to a certain extent
Little friction noise.
Above-described is only embodiments more of the present utility model.Ordinary skill for this area
For personnel, on the premise of creating design without departing from this utility model, it is also possible to make some deformation
And improvement, these broadly fall into protection domain of the present utility model.
