The ramp with the structure disclosed by the utility model is easy to replace wood beams and low in maintenance and use cost.
Description
Technical field:
The utility model relates to a kind of ramp, is specifically related to a kind of crawler belt armored vehicle test and uses ramp.
Background technology:
The novel crawler armored vehicle of China's development, adopts metal track walking structure, conducts oneself with dignity 55 tons, and power reaches 1103kw, is subject to the low-frequency vibration of certain amplitude in travelling.The at present concrete ramp of test use, due to metal track and concrete friction factor lower, cause track adhesion inadequate, even if climb up by sheer good luck ramp, due to the vibrations of power, transmission system low frequency, will make vehicle accelerate along ramp to glide, very easily produce motor and fall quick-fried accident.
In addition, the ramp of single concrete structure, when vehicle passes through concrete structure surface, be subject to crawler belt extruding easily to cause avalanche, friction factor domatic after using several times reduces, and the danger of climbing increases, can not meet instructions for use, finally scrap, cause the use cost in ramp high, and can not meet bulk trial demand.
Summary of the invention:
The utility model utilizes natural hill, and on land waste, building, with the steel concrete ramp of expanded metal lath cell, location flitch and carrying flitch, has solved existing ramp metal track and concrete friction factor is lower, fragile and cost is high problem.
The utility model is realized by following technical scheme:
Ramp is used in a kind of crawler belt armored vehicle test, comprise natural hill, through clearing up the land waste ramp on the natural hill that reaches crawler belt armored vehicle support strength, steel concrete ramp matrix, reinforcing cage, expanded metal lath cell, carrying flitch and spacing flitch, steel concrete ramp matrix is embedded on land waste ramp by steel concrete foundation pile, reinforcing cage and expanded metal lath cell bottom weld together, be embedded in the matrix of steel concrete ramp, and with steel concrete ramp matrix one moulding by casting, steel concrete ramp matrix is exposed on expanded metal lath cell top, carrying flitch and location flitch embed wherein, flitch two ends, location withstand on respectively on the steel plate and carrying flitch of expanded metal lath cell, location flitch is fixed on the matrix of steel concrete ramp by road bolt, on carrying flitch, be embedded with the anti-skidding railway spike exposing, the space recess on expanded metal lath cell top adds compactness, compressive strength and hardness reach the climbing of crawler belt armored vehicle and support the soil requiring.
Be cast on the steel plate of the expanded metal lath cell bottom in the matrix of steel concrete ramp and have hole.
The crushing strength of natural hill is not less than 100kg/cm2.
Add in the native compactness of space, expanded metal lath cell top recess and reach more than 97%, compressive strength is not less than 7.6kg/cm2, and Shao Shi C hardness is not less than 35.
In the utility model, when the ramp surface of vehicle by expanded metal lath cell structure, utilize crawler belt rake teeth to be bumped into relatively soft soil and carrying flitch, the additional railway spike hook rake teeth of stumbling, guarantees that vehicle climbing passes through; Locate flitch to the extruding of carrying flitch, prevent from carrying flitch and be subject to the overturning of crawler belt active force, to counter-force of carrying flitch to prevent turning over spacing.Soil is beneficial to crawler belt and is bumped into wherein, increases track adhesion.This structure ramp surface is easy to change flitch, safeguards, use cost is low.
Accompanying drawing explanation:
Fig. 1 is the utility model section structure schematic diagram, is also the A-A sectional view of Fig. 2;
Fig. 2 is the top plan view structural representation of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 2, is also that carrying flitch adds railway spike structural representation;
Fig. 4 is the C-C sectional view of Fig. 2, is also spacing flitch extruding carrying flitch structural representation.
The specific embodiment:
As Figure 1-4, the utility model utilizes natural hill (crushing strength of natural hill is not less than 100kg/cm2), builds high inclination-angle (32 ° of left and right) steel concrete ramp matrix 7 on land waste ramp 6.Steel concrete ramp matrix 7, by steel concrete foundation pile 8, is embedded in land waste ramp 6 (be generally granite, can reach the support strength of crawler belt armored vehicle climbing) upper, in case steel concrete ramp matrix 7 comes down.
On steel concrete ramp matrix 7 domatic, increase expanded metal lath cell 4 (the thick 17mm of expanded metal lath cell 4 edge steel plate being embedded on reinforced concrete structure face, the thick 15mm of middle steel plate), steel concrete ramp matrix 7 is exposed on expanded metal lath cell 4 tops, reinforcing cage 10 in bottom and steel concrete ramp matrix 7 concrete structures welds together, and cast one forms.And, imbed and on the steel plate of expanded metal lath cell 4 bottoms in steel concrete ramp matrix 7, have the concrete hole 9 of flowing, be beneficial to the concrete bonding that mutually flows.
Expose in the upper steel expanded metals cell 4 of steel concrete ramp matrix 7 and be inlaid with the carrying flitch 2 of 200 × 200 × 1800mm and the location flitch 1 of 150 × 150 × 200mm.On carrying flitch 2, be embedded with the anti-skidding railway spike 3 that exposes 30mm, location flitch 1 is fastened 11 by road and is fixed on steel concrete ramp matrix 7.Space recess in upper steel expanded metals cell 4, fills and leads up with soil 5, pushes space between flitch.Soil 5 should guarantee that its compactness reaches more than 97% in the time of construction, and compressive strength is not less than 7.6kg/cm2, and Shao Shi C hardness is not less than 35.In practice, this soil is made up of clay, stone, pitch, cellulose and lime.
The utility model can make metal track and concrete friction factor reach 0.48-0.52.
