Description

Technical Field

[0001] The utility model relates to the technical field of movable concrete mixing stations, in particular to a movable new energy mixing station platform for tunnel construction. Background Art

[0002] Concrete must be stirred continuously during transportation to effectively prevent solidification and drying. Concrete mixer trucks mainly convert the engine power into the power of the hydraulic oil pump through the power take-off device of the mixer truck. Then, the pressure generated by the hydraulic oil pump converts the hydraulic oil into mechanical energy through the hydraulic motor to generate speed and torque to provide the final power for the reducer to drive the overall rotation of the mixing tank. There is also a mobile concrete mixing station used for tunnel construction. The mixing tank is set on a trailer, and the rotation of the mixing tank itself is also driven by a hydraulic motor. However, in the tunnel, which is different from the outdoor environment, the use of a diesel engine to maintain the continuous rotation of the mixing tank will lead to a large amount of exhaust gas in the tunnel, causing air pollution in the tunnel. In addition, the oxygen-deficient environment is not conducive to the operation of the diesel engine. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] Embodiments of the present utility model:

[0025] like Figure 1-Figure 3 As shown, the mobile new energy mixing station platform for tunnel construction includes a power battery 3, a motor controller, a motor and a mixing tank 2. The mixing tank 2 is arranged on the chassis 1 of the trailer, which is the prior art. The difference is that the power battery 3 is used to supply power, replacing the traditional driving system such as hydraulic motors, thereby solving the problem of fuel emission polluting the air in the tunnel.

[0026] The power battery 3, the motor controller, and the motor are all arranged on a base. The bottom of the power battery 3 is provided with a plurality of bolt holes, which are fixed to the base by bolts. The base adopts a metal frame, and the drive control system and the base are hoisted and installed on the chassis 1 of the trailer as a module (after the original drive system is removed, the space left is just enough to install the new energy drive control system). For the convenience of description, the power battery 3 is defined to be located in front of the mixing tank 2, that is, in the length direction of the chassis 1.

[0027] The output interface of the power battery 3 is electrically connected to the motor controller, the motor controller is connected to the motor, the motor is drivingly connected to the rotating shaft at one end of the stirring tank 2, the motor drives the stirring tank 2 to rotate, and the motor controller can control the motor speed.

[0028] The power battery 3 is in the shape of a rectangular parallelepiped, and its length direction is placed along the width direction of the chassis 1. The power battery 3 adopts a lithium iron phosphate battery cell, which is a large-capacity battery of 36KWh. A full charge can satisfy the operation of the mixing tank 2 for about 12 hours. The power battery 3 is provided with a discharge-specific output interface on the side facing the mixing tank 2, which is a high-voltage DC output port 37DC345.6V, which is a standard DC charging port. The output interface is for the charging gun to be plugged in, and is connected to the motor controller through the charging gun (not shown). In order to distinguish it from the charging gun behind, the charging gun used for discharge here is recorded as the first charging gun, that is, it supplies power to the motor. The structural form and principle adopt the form of the current charging gun.

[0029] A control panel area is provided on one side of the chassis 1 of the trailer in the width direction of the power battery 3 for easy operation. A charging interface is provided in the control panel area, and the charging interface is used to charge the power battery 3. The charging interface includes an AC charging interface and a DC charging interface 32. Of course, only one of them can be provided in other embodiments. The DC charging interface 32 is a standard DC charging port with a power of up to 28KW and a very fast charging speed. More than 80% of the capacity can be charged in 1 hour. The AC charging interface has two specifications: AC380V charging interface 34 and AC220V charging interface 33. Using the AC380V charging interface 34, it can be fully charged in five hours; the AC220V charging power is relatively small, and it can be used as a backup for emergency use. When charging is needed, after the mixing tank is towed outside the tunnel by the trailer, the above-mentioned power battery is charged using a charging pile, and the charging gun on the charging pile is recorded as the second charging gun.

[0030] The discharge interface and the charging interface are set separately, supporting charging while using, which can ensure the long-term and continuous rotation of the mixing tank.

[0031] Furthermore, the control panel area is also provided with an AC220V output port 35 and a USB interface 36. The AC220V output port 35 can be used to power lighting equipment, small electric tools, etc. when necessary, and the output port is not necessarily provided. The USB interface 36 is used when the battery system is upgraded.

[0032] The control panel area is provided with a display screen 31, which can display information such as charging and power consumption. An openable protective door 39 is provided on the outside of the control panel area. The protective door 39 is set as a transparent area at least at the corresponding display screen 31, and can be made completely transparent. The protective door 39 is mainly used to shield and protect various charging interfaces and the display screen 31. One side can be hinged, and the conventional installation method of the existing door is adopted. When charging, open the protective door; when charging is completed, close it.

[0033] The side wall of the power battery 3 is provided with a plurality of lifting rings 38, which are used in conjunction with a flat lifting belt. When the power battery 3 is installed on the base, and when the entire battery module is installed on the trailer, lifting operations can be performed.
