Support transport vehicle with double engines

Abstract

The invention belongs to the field of mine machinery and particularly discloses a support transport vehicle with double engines. The support transport vehicle with the double engines comprises a front vehicle frame, a U-shaped framework, a shaft pin, a power driving system and a backup camera system. The two anti-explosion engines can be started simultaneously to promote power and tractive force, when one engine breaks down, the other engine can provide motive power, the support transport vehicle is driven to a maintenance working surface, and therefore production is not affected, the whole vehicle is compact in structure, and a hydraulic oil tank is arranged in the middle of the U-shaped framework. The hydraulic oil tank is placed in the middle of the front end of the rear part of the vehicle, and the capacity of a diesel tank can be effectively increased due to the unique position of the hydraulic oil tank.

Description

technical field [0001] The invention belongs to the field of mining machinery, and in particular relates to a dual-engine support transport vehicle. Background technique [0002] With the industrialization and modernization of coal mines, the production capacity of coal mines has gradually increased. The hydraulic supports used in new mines are getting bigger and bigger. At present, there are two problems in the practical use of the support trucks: 1. The existing support trucks all use an explosion-proof diesel engine, which is obviously insufficient in power due to the limitation of the explosion-proof diesel engine. If a single engine fails, the pallet truck will be parked in the roadway, and other vehicles will not be able to pass. If it cannot be repaired in a short period of time, it can only be towed by a tractor to the maintenance work surface. This situation is not only time-consuming, but also reduces production. 2. The hydraulic oil tanks of the support trucks ...

AI Technical Summary

Problems solved by technology

The hydraulic supports used in new mines are getting bigger and bigger. At present, there are two problems in the practical use of the support trucks: 1. The existing support trucks all use an explosion-proof diesel engine. Due to the limitation of the explosion-proof diesel engine, the power is obviously insufficient

If a single engine fails, the truck will stop in the roadway and other vehicles will not be able to pass

If it cannot be repaired in a short period of time, it can only be towed by a tractor to the maintenance work surface. This situation is not only time-consuming, but also reduces production.

2. At present, the hydraulic oil tanks of the support trucks on the market are all placed on the front frame, occupying the position of the diesel tank, resulting in a small effective volume of the diesel tank, short continuous working time, frequent refueling, and seriously affecting work efficiency.

Of course, improvement measures have been proposed in other industries for the first problem. For example, the patent application No. 201110285406.5 discloses a dual-engine aircraft tractor, which also solves the problem of insufficient power of the tractor. In order to control the two engines respectively, this point can be learned from the [0003] paragraph of the content of the invention of the application. One of the technical solutions is unnecessary, because even in the no-load state, no matter whether two engines or one engine is turned on, the The energy consumption is the same, and the second is that two sets of mechanical accelerator pedals must be used to drive. In other words, this technical solution does not solve the technical problem of one accelerator pedal simultaneously controlling the start of two engines, which increases the difficulty of operation.

3. Affected by the volume factor of the carrier truck, the driver's field of vision in the cab is greatly limited, and it is difficult to accurately judge the reversing distance and observe the road obstacles behind, and the single reversing rearview system on ordinary cars is not enough to solve this problem
