Problems solved by technology

[0003] The model of the muck truck is usually named by the capacity of the muck hopper, that is, different types of muck trucks have different hopper capacities, and the models of the matching chassis and bogies are also different. Due to the complex structure of the bogie, small Capacity 13m 3 There are many models of the following dirt trucks, and the components of different types of bogies are not universal, so a large number of parts and components are added in specific use, resulting in procurement costs, logistics costs, manufacturing costs and after-sales service The cost is generally higher, in this context the 13m 3 It is imminent to optimize the design of the following light-duty dirt trucks

Embodiment Construction

[0023] Such as Figure 3-11 As shown, the embodiment of the present invention provides a light rail earth muck truck, which includes:

[0024] The slag hopper 3 is used to hold the slag and is symmetrical about the center line 30; both ends have a lifting shaft 31 for hoisting and a rotating shaft 32 for supporting; the connection line between the centers of the two lifting shafts 31 and the slag hopper The center line 30 coincides, and the line connecting the centers of the two rotating shafts 32 is located on the same side of the center line 30 of the slag hopper; see Figure 3-5 ;

[0025] The bottom frame 2 is used to carry the slag hopper 3. On the top surface, there are two positioning plates 23 adapted to the positions of the rotating shafts 32. The positioning plates 23 are provided with U-shaped grooves 24, and the rotating shafts 32 are respectively placed in the U-shaped grooves. 24 inside; both ends have a traction coupling 21 for connection; see Figure 6-8 ; ...

Abstract

The invention discloses a light rail soil residue vehicle. The light rail soil residue vehicle comprises a residue bucket, an underframe, a walking part and an air braking system, wherein the residue bucket is symmetrical with respect to the center line. Lifting shafts and rotating shafts are positioned at two ends of the residue bucket, the central connection line of the two lifting shafts and the center line of the residue bucket coincide, and the central connection lines of the two rotating shafts are located on the same side of the center line of the residue bucket. The top surface of the underframe is provided with two positioning plates, the positioning plates are provided with U-shaped grooves, the rotating shafts are placed in the U-shaped grooves, and pull type coupling devices are positioned at two ends of the underframe. The walking part comprises two wheel sets, every wheel set comprises an axle, two wheels and an axle box body, and the underframe is supported on the axle box body through an elastic element. The air braking system comprises four braking units, every braking unit comprises a braking cylinder, a connecting rod and a brake shoe, wherein the braking cylinder is fixed on the underframe, one end of the connecting rod is pivoted to the underframe, and the other end of the connecting rod is pivoted to a braking cylinder piston rod. The same underframe, the walking part and the air braking system are used for soil residues of various models, kinds of parts are greatly reduced, and the purchase cost, the logistics cost, the manufacturing cost and the after-sale service cost are greatly reduced.

Description

technical field [0001] The invention relates to the technology of supporting vehicles behind industrial and mining vehicles used in construction, in particular to a light rail earth muck vehicle. Background technique [0002] The soil muck truck is used to dump the excavated soil dregs to the unloading area in the shield tunnel construction of the subway tunnel. Due to the different geological conditions in the shield tunneling construction, shield machines of different specifications and models are used, resulting in the parameters of locomotives and vehicles. The individual needs are quite different, especially it is necessary to choose soil muck trucks with different capacities, such as figure 1 As shown, the existing muck truck is mainly composed of bogie 1, underframe 2 and slag bucket 3, and the bogie is the running mechanism of the muck truck, and every muck truck has two bogies. When the muck car is running, it is steered by the bogie's core disc, damped by the bogi...
