[0002] At present, the battery replacement station for pure electric concrete mixer trucks refers to facilities that provide battery replacement and charging services for pure electric concrete mixer trucks. Pure electric concrete mixer trucks are concrete mixer trucks that use electric drive systems instead of traditional fuel engines. Compared with traditional fuel mixer trucks, pure electric concrete mixer trucks have the characteristics of zero emissions. Pure electric concrete mixer trucks use batteries as energy, do not produce tail gas and exhaust gas emissions, and effectively reduce air pollution. Since the driving distance and operating time of pure electric concrete mixer trucks are limited by battery capacity and cruising range, it is necessary to build a battery replacement station to solve the cruising range problem. At present, the battery replacement process of the traditional pure electric concrete mixer truck battery replacement station is as follows: the vehicle arrives at the designated location, the lifting mechanism moves to the top of the vehicle battery box, and the vehicle battery box is lifted to the charging area. Then the lifting mechanism selects a group of fully charged battery boxes and lifts the fully charged battery box to the top of the pure electric concrete mixer truck for cooperation. Finally, the lifting mechanism returns to the equipment to reset. The traditional battery replacement station takes too long to take and store the body battery and take and install the fully charged battery, and the battery replacement efficiency needs to be improved. Therefore, we propose a new energy charging and battery replacement integrated pure electric concrete mixer truck battery replacement station. Utility Model Content

A steel wire rope is wound around the outside of the winding drum 403, and the bottom end of the steel wire rope is fixedly connected to the top surface of the grabbing platform 405.

[0028] Grooves for accommodating the clamping strip 406 are formed on both side walls of the rectangular frame seat 407 . The clamping strip 406 is embedded in the grooves. Cylinder groups 408 connected to the clamping strip 406 are fixedly provided on both sides of the inner wall of the rectangular frame seat 407 .

[0029] In a specific embodiment of the utility model, the tank chain transport mechanism 1 7 and the tank chain transport mechanism 2 8 are both composed of a conveying shaft, a tank chain and a stepper motor. The stepper motor drives the tank chain to move at a precisely set distance. The block group 701 arranged on the surface of the tank chain is composed of four blocks. The four blocks are arranged in pairs. The spacing between the two teams of blocks is 40 mm larger than the narrow side width of the fully charged battery box 101. The block group 701 is used to engage with the battery box to limit the position, so as to ensure the position stability of the battery box during tank chain transportation.

[0030] The pure electric concrete mixer truck 2 is accurately parked in the middle area set between the battery storage mechanism A1 and the battery storage mechanism B3.

At this time, the fully charged battery box 101 is transferred to the pure electric concrete mixer 2, and the replaceable battery box 201 is moved to the tank chain transport mechanism 2 8 of the battery storage mechanism B3, and then the push rod of the cylinder group 408 is controlled to retract and the grabbing platform 405 is lifted. Then it moves and resets, and the battery replacement step of the pure electric concrete mixer truck 2 is completed. At this time, the fully charged battery box 101 on the tank chain transport mechanism 7 moves toward the front end by the distance of a battery box to fill the gap of the fully charged battery box 101 after replacement. Then the tank chain transport mechanism 28 transports the power-deficient replaceable battery box 201 to the bottom of the gantry lifting frame 25, and transports the replaceable battery box 201 back to the battery storage mechanism A1 through the gantry lifting frame 25 and charges it, thereby realizing the cyclic battery replacement management.
