At present, a shield construction traction locomotive is a traction device for rail vehicle transportation, and is widely applied to engineering construction of various mines, urban rail transit, water conservancy tunnels and the like. With the large-scale exploitation of underground mines and the construction of subway and water conservancy construction industries and the trend of the development of TBM tunneling technology, the large-tonnage and large-traction locomotive has a considerable market prospect. The traction locomotive utilizes the power generated by a traction motor or other power machines, drives a driving wheel (driving wheel) through a locomotive transmission device, and generates a driving force, namely locomotive traction force, by virtue of certain adhesive force between the driving wheel and a steel rail.
As shown in fig. 1-3, the existing large-tonnage tractor for shield construction basically has three axle modes: fig. 1, a two-axle locomotive (one tractor has two moving axles and four wheels); the structure can not meet the traction output of a large-tonnage shield construction traction electric locomotive (particularly a 60-ton tractor and above), exceeds the axle weight limit, has insufficient adhesive force, and requires that the tractor is output when the tractor has low speed and large torque and starts on a ramp frequently in the special use requirement of tunnel shield construction, so that the wheel slip is easy to occur; when the traction locomotive brakes, the tractor is not easy to brake and wheels are easy to wear due to the inertia of large-tonnage running of the vehicle.
FIG. 2, a locomotive with one moving axle and one bogie (1 independent moving axle and one bogie with 2 moving axles on the bogie for a total of 6 wheels); the manufacturing cost is high, the processing technology is complex, the requirement on installation strength is high, the maintenance and the overhaul are troublesome, and the whole frame is required to be disassembled and hung for maintenance and repair of the bogie.
Fig. 3, two bogie locomotives (2 bogies with 2 moving axles on each bogie, respectively, for a total of 8 wheels). The manufacturing cost is higher, the processing technology is complicated, the requirement on the installation strength is high, the maintenance and the overhaul are troublesome, and the whole frame can be maintained and maintained only by disassembling and hanging the whole frame for the maintenance of the bogie. The tractor is suitable for tractors with the weight of more than 75 tons.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides the bogie-free three-shaft shield construction traction locomotive which is simple in structure, low in manufacturing cost, simple in processing technology, low in installation strength requirement and convenient to maintain and overhaul.
The technical scheme adopted by the utility model is as follows: a three-shaft shield construction traction locomotive without a bogie comprises a frame, wherein three groups of axle box bodies are arranged at the bottom of the frame, and each group of axle box bodies comprises two axle box bodies symmetrically arranged on two sides of the frame; in the three groups of axle box bodies, the front axle box body is arranged on the frame through two rubber springs, the rear axle box body is arranged on the frame through two rubber springs, and the top of the middle axle box body is arranged on the frame through a plurality of spiral springs; each set of axle box body is provided with an axle, and the two ends of the axle are respectively provided with wheels.
In the three-shaft shield construction traction locomotive without the bogie, the sections of the front axle box body and the rear axle box body in the three sets of axle box bodies are isosceles trapezoids with small upper parts and large lower parts; two side surfaces of the axle box body are connected with the frame through rubber springs.
In the bogie-free three-shaft shield construction traction locomotive, the frame is provided with a shaft box guide block corresponding to the shaft box body in the middle, the shaft box guide block is provided with a shaft box guide groove, the shaft box body in the middle is arranged in the shaft box guide groove, the top of the shaft box body in the middle is connected with the top of the shaft box guide groove through two spiral springs, and the two spiral springs are connected in parallel; the top of the axle box guide groove is provided with two spring positioning blocks corresponding to the two spiral springs, and the two spring positioning blocks are respectively positioned in the two spiral springs.
Compared with the prior art, the utility model has the beneficial effects that:
a. the utility model has relatively simple structure;
b. the utility model has uncomplicated processing technology, does not have a bogie mode, and can output the traction force and the braking force of the tractor with the bogie;
c. the utility model is more convenient to maintain and has good accessibility;
d. the wearing part of the utility model is easy to replace and has low manufacturing cost.
