Abstract
The utility model relates to the mining mechanical field, in particular to a novel mining rest-transport flat car capable of bearing 30T, which solves the problems that when the prior old mine tunnel rail-travels hydraulic supports, the consumption of labor, materials and financial resources and the like is caused due to small bearing capability and high height of flat cars. The flat car comprises a car frame and a wheel assembly, and is characterized in that the car frame is a welding frame structure which is by means of taking steel I-beam as main carrier bars, a traction connecting bar of which two ends have moveable connecting heads is further arranged in front of the car frame, the wheel assembly employs a double-row conical bearing enclosed structure, wheels adopt a cast structure, and a car frame slip and the steel I-beam employ a riveted mode to connect. The intensity of the flat car can satisfy the requirement of bearing 30T, the height of the whole car is the height of the flat car plus the height of a support and is shorter than the height of a down-hole string, the string space is reserved, the stability is good when the flat car bears the support, which can be applicable to the gauge of 600 mm, the flat car has the advantages of simple structure, rational design, low manufacture cost and good use effect, and is particularly to be applicable to old mines with narrow tunnels and small space.
Description
Technical field
The utility model relates to mining field of transport vehicles, is specially the new type mining fortune frame flat truck of a kind of 30T of carrying.
Background technology
Development along with fully-mechanized mining equipment, the more and more large-scale change of hydraulic support, China's coal-mine down-hole rail transports heavy hydraulic support at present, because old mine laneway condition is bad, gauge is little, turn radius is little, the gradient is bigger, and original flat truck intensity difference, bearing capacity are less, and be highly higher and make the tunnel bottom-to-top-height can't satisfy the stringing requirement of large hydraulic support, under the situation of big in the gradient simultaneously or bend, can't normally drive a vehicle, need field by using with measures such as gradient reductions, cause the consumption of a large amount of human and material resources, financial resources, and setup time is produced in prolongation.
Summary of the invention
When the utility model transports heavy hydraulic support in order to solve existing old mine laneway rail, owing to little, the highly high defective of used flat truck bearing capacity causes problems such as the consumption of human and material resources, financial resources and production cycle be long, provide the new type mining fortune frame flat truck of a kind of 30T of carrying.
The utility model is to adopt following technical scheme to realize: the new type mining fortune frame flat truck of a kind of 30T of carrying, comprise vehicle frame and be installed in vehicle frame below and the wheel that cooperates with underground orbit right, vehicle frame the place ahead is provided with and tractor equipment bonded assembly chain, and innovative point of the present utility model is that vehicle frame is by the lead frame structure of I-beam section as main carrier bar; Vehicle frame the place ahead also has additional two ends and is respectively equipped with the traction link that flexibly connects head.Adopt structure design of the present utility model, vehicle frame can be under the condition of proof strength, reduce the whole height of flat truck effectively, guarantee the stringing height, improve flat truck stability, and the flexible connection head of the traction link in vehicle frame the place ahead by two ends is hinged with vehicle frame, tractor equipment respectively, traction link can be rotated up and down, have certain adjustment surplus and buffering effect, guarantee the normal driving on planar curve path and the vertical bend.
In order further to improve flat truck intensity, to reduce its height, the described wheel all adopting biserial conical surface bearing enclosed construction reduces its scantling of structure as far as possible under the condition of proof strength, to reduce the height of flat truck, each wheel adopts the block cast structure, can increase the wheel loading strength.
Described vehicle frame slips adopts the riveted joint mode to be connected with I-beam section, can reduce stress concentration, improves antifatigue and anti-brittle failure ability.
Compared with prior art, adopt fortune frame flat truck described in the utility model can realize whole transportation of rail of coal mine fully-mechanized mining working large hydraulic support, problems such as load-bearing, bend, climbing and head-room restriction in the time of can solving simultaneously the heavy hydraulic support of transportation, concrete effect is as follows:
1, this flat truck intensity satisfies the requirement of carrying 30t;
2, the car load height be flat truck height and support height sum less than down-hole stringing height, and be reserved with the stringing space;
3, flat truck carrying support rear stability is good, and during applicable to the 600mm gauge, horizontal minimum profile curvature radius is not less than 12m, and vertical minimum profile curvature radius is not less than 15m, and in easy flights in 20 ° tunnel, margin of stability is greater than 1.5;
In a word, the utility model is simple in structure, reasonable in design, cost of manufacture is low, result of use is very good, is particularly useful for the old mine that the tunnel is narrow, the space is little and transports heavy hydraulic support.

Among the figure: 1-vehicle frame 2-underground orbit 3-wheel flexibly connects a 8-traction link to 4-chain 5-I-beam section 6-vehicle frame slips 7-
The specific embodiment
A kind of new type mining fortune frame flat truck that carries 30T, as shown in Figure 1, 2, comprise vehicle frame 1 and be installed in vehicle frame below and the wheel that cooperates with underground orbit 2 to 3, constitute by two groups of wheels facing each other, wheel all adopts biserial conical surface bearing enclosed construction to 3, and each wheel adopts the block cast structure; Vehicle frame 1 the place ahead is provided with and two chains 4 of tractor equipment bonded assembly; mainly shield; setting up two ends between the chain is respectively equipped with and flexibly connects a traction link 8 of 7; vehicle frame 1 is by the lead frame structure of I-beam section 5 as main carrier bar, and vehicle frame slips 6 adopts the riveted joint mode to be connected with I-beam section 5.
In the practical application, the heavy hydraulic support that is transported is fixed on the vehicle frame of flat truck, tractor equipment connects to ground by chain and traction link, drives fortune frame flat truck and orbits, and reaches the purpose of load transfer device.When flat truck connects operation firmly by the locomotive haulage connecting rod when gallery transports, move by the winch towing bracket in the time of on the ramp.
