Problems solved by technology

In this lifting system, the normal position of the reversing valve of the oil pump is the rising position, and the hydraulic lock is opened by the momentum of the oil, but the system does not provide a reliable oil return system, and the return of the hydraulic lock needs to be decompressed through the oil return. Realization, without the corresponding oil return system, it is difficult to guarantee the reliability of the return operation
Moreover, since the normal position of the reversing valve of the oil pump is the rising position, once a control error occurs, the cab will turn over, posing a great safety hazard
At the same time, the operation of the system requires manual cooperation, and the operation process is complicated and inconvenient.

Embodiment 1

[0035] Embodiment 1: An application of a battery pack quick change and locking system based on a non-differential cab lift and flip system.

[0036] The battery pack quick change and locking system includes a cab lifting and turning hydraulic system 1 (oil pump 1.1 / 1.2, reversing valve 1.3, oil cylinder 1.4), a power-changing control valve group module 2, and a power-changing locking module 3 , Lift and replace the electronic control module 4. The connection relationship is as attached Figure 1.5a shown, . The power exchange control valve group module 2 is in communication with the lowering circuit of the cab lifting and turning hydraulic system 1, specifically the 2P-Y oil port of the power changing control valve group module and the lifting reversing valve in the lowering circuit of the cab lifting and turning hydraulic system 1 1.3 is connected to the oil port 1B1-Y between the lifting cylinder 1.4, and the oil port 2A-Y of the electric control valve group module is conne...

Embodiment 2

[0051] Embodiment 2: An application of a battery pack quick change and locking system based on a differential cab lift and flip system.

[0052] The battery pack quick change and locking system includes a cab lifting and turning hydraulic system 1 (oil pump 1.1 / 1.2, reversing valve 1.3, oil cylinder 1.4), a power-changing control valve group module 2, and a power-changing locking module 3 , Lift and replace the electronic control module 4. The connection relationship is as attached Figure 1.6 shown. Compared with Embodiment 1, only the lift cylinder 1.4 is replaced with a differential cylinder, and the lift reversing valve 1.3 is replaced with a differential lift valve. The other modules are connected in the same way and have the same functions. This is the advantage of the logic design of the present invention. High practicality.

Embodiment 3

[0053] Embodiment 3: An application of a battery pack quick change and locking system based on a single-acting oil cylinder-based cab lifting and turning system.

[0054] The battery pack quick change and locking system includes a cab lifting and turning hydraulic system 1 (oil pump 1.1 / 1.2, reversing valve 1.3, oil cylinder 1.4), a power-changing control valve group module 2, and a power-changing locking module 3 , Lift and replace the electronic control module 4. The connection relationship is as attached Figure 1.7 shown. Compared with Embodiment 1, the lift cylinder 1.4 is a single-acting cylinder, the lift reversing valve 1.3 is a two-position three-way valve, and the oil inlet 2P-Y of the power exchange control valve group module 2 is connected to the oil outlet of the oil pump 1. Port 1P-Y; The oil outlet 2A-Y of the power-changing control valve group module 2 is sealed, and the other modules are connected in the same way and have the same function. This is the advant...

Abstract

The invention relates to a battery pack quick-changing and locking system of an electric heavy truck, which relates to the technical field of transportation and mainly comprises a cab lifting and overturning hydraulic system, a battery changing control valve group module, a battery changing locking module, a lifting battery changing control module, a battery pack, a frame, a connecting pipeline, a line, a bolt and the like. The system is mainly used for locking a battery pack and a frame bracket, shares a power source with a cab lifting and overturning system of a battery replacement heavy truck, and accords with actual operation: the cab cannot be overturned during battery replacement, the battery is not replaced during cab overturning, and the two operations cannot be performed at the same time; the new energy battery replacement heavy truck battery pack can be quickly and reliably replaced and locked at low cost, and meanwhile the reliability of an existing cab lifting and overturning system can be improved.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a battery pack quick change and locking system for an electric heavy truck. Background technique [0002] With the gradual advancement of the "five modernizations" in the transportation industry, more and more pure electric heavy trucks have entered substantive applications in the transportation industry and achieved good economic benefits. However, the battery pack, the power source of pure electric heavy trucks, is becoming the bottleneck for the development of pure electric heavy trucks: to increase the cruising range, a larger battery pack is required, and the larger the battery pack, the larger the volume and weight, and the greater the economic benefits. Low. In order to solve this problem, the heavy electric truck adopts the "battery swap" technology: the battery pack is used as a standard size and is connected to the heavy truck through a quick detachable system. ...
