Problems solved by technology

[0004] 1) When the diesel-powered concrete pump truck is working on a construction site with sufficient power, it can only work through the diesel engine to drive the equipment, and cannot use the external power supply on the construction site to provide power for the whole vehicle
Since the diesel engine consumes a lot of fuel and produces a lot of noise when working, it has to be driven by a diesel engine when it is possible to drive the equipment with electricity. This construction method not only increases the cost of use but also pollutes the surrounding environment.
[0005] 2) When the electric-driven concrete pump truck is working on a construction site without sufficient power supply, it cannot obtain power through the vehicle's external power supply interface, which greatly limits the scope of use of the electric-driven concrete pump truck
[0006] 3) Since the current concrete pump truck does not have a pumping system buffer device, when the concrete pump truck is working, the huge impact brought by the pumping system cannot be alleviated, which will cause the concrete pump truck to vibrate violently, which greatly provides the possibility of failure. possibility and shortened equipment life

Embodiment 1

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] see figure 1 , figure 2 , image 3 , Figure 4 , diesel-electric dual-power concrete delivery pump truck, the chassis of the car is equipped with an external power supply interface 23, and a transfer case 3 is installed on the chassis of the car, and one end of the transfer case 3 is connected with the chassis engine 2 through a transmission shaft to obtain the power of the chassis engine 2 , the other end of the transfer case 3 is respectively connected with the vehicle-mounted generator 5 and connected with the vehicle chassis traveling device 7 through the transmission shaft 6 . The on-board generator 5 provides power for the whole vehicle and simultaneously drives the motor 8 on the chassis of the vehicle. The motor 8 drives the hydraulic pump unit 9 of the pumping system to provide power for the pumping system. In this way, the power of chassis engine ...

Embodiment 2

[0031] see Figure 5The difference between this example and Example 1 is that the buffer device 6 installed on both sides of the pumping system washing chamber 11 and the pumping hopper 13 is cancelled, and the concrete delivery port 14, the concrete moving delivery pipe 17, the hollow piston 18 and the hollow piston are cancelled. 20. Connect the fixed concrete delivery pipe 19 directly to the pumping hopper 13, and simultaneously cancel the flexible connection between the concrete delivery port 14 and the pumping hopper, allowing concrete to be directly input into the hopper from the upper opening of the pumping hopper 13.

Abstract

The invention provides a novel diesel-electric dual-power truck-mounted concrete conveying pump truck which is driven by diesel power or electric power and can freely switch between the two kinds of power. The truck comprises a truck chassis, and is characterized in that: the truck chassis is provided with a power providing device and a pumping device; the power providing device comprises an external power interface and a truck-mounted power generation device; the truck-mounted power generation device comprises a truck chassis engine, a transfer case and a truck-mounted generator; one end of the transfer case is connected with the truck chassis engine, and the other end of the transfer case is connected with the truck-mounted generator and a truck chassis driving device respectively; and the pumping device is driven by an electric motor through electric power. The novel truck-mounted concrete conveying pump truck can be provided with a buffering device of a pumping system, can effectively reduce the impact of the pumping system on a truck body, and prolongs the service life of equipment.

Description

technical field [0001] The invention relates to a diesel-electric dual-power concrete conveying pump vehicle capable of freely switching diesel engine drive and electric drive. In addition, the diesel-electric dual-power concrete delivery pump truck can also be equipped with a pumping system buffer device, which reduces the huge impact of the concrete pumping system on the car body, thereby greatly increasing the service life of the equipment. Background technique [0002] At present, there are two types of concrete conveying pump trucks: diesel-powered concrete conveying pump trucks with diesel engine-driven pumping hydraulic pumps installed on the chassis of automobiles, and electric-driven concrete conveying pump trucks driven by external power supplies to drive motors and pumping hydraulic pumps. [0003] These two existing concrete delivery pump trucks have the following determinations: [0004] 1) When the diesel-powered concrete pump truck is working on a constructio...
