Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

Example 1

As shown in fig. 1-4, the self-propelled trolley sand-lifting and sand-breaking system comprises two sand tank assemblies 1, two lifting frame bodies 3 and two self-propelled trolley assemblies 2, wherein two ends of each lifting frame body 3 are respectively fixed at the tops of the two sand tank assemblies 1, and a part of each lifting frame body extends out of the sand tank assembly 1 and is used for lifting sand bags; the sand tank assembly 1 comprises a tank body frame, and a sand tank and a sand discharge hopper which are sequentially arranged on the tank body frame;

the self-propelled trolley assembly 2 comprises a self-propelled trolley frame body 4, a lifting hook 5, a steel wire rope 6, four idler wheels 7 with motors and a winch 8, wherein the four idler wheels 7 with the motors are arranged on the self-propelled trolley frame body 4, the motors are arranged on the idler wheels 7 through pin shafts, and the motors drive the idler wheels to rotate, so that the self-propelled trolley assembly 2 can move forwards and backwards; one end of the steel wire rope 6 is wound on the winch 8, the other end of the steel wire rope is connected with the lifting hook 5, an I-shaped steel slide rail 11 penetrating through the hoisting frame body 3 is arranged on the hoisting frame body, the roller 7 of the self-propelled trolley assembly 2 is arranged in the I-shaped steel slide rail 11, and the self-propelled trolley assembly 2 can move back and forth in the I-shaped steel slide rail 11. The both ends of hoisting frame body 3 all are equipped with the stop device that the restriction dolly subassembly 2 moved by oneself, avoid dolly subassembly 2 roll-off hoisting frame body 3 by oneself.

Wherein the specific sand adding process is as follows: the motor drives the self-propelled trolley assembly 2 to move in the I-shaped steel slide rail 11 to the outside of the sand tank assembly 1, then the winch 8 starts to work, the lifting hook 5 is lowered to a lifting point, and a worker at the bottom hangs a sand bag on the lifting hook 5; then the winch 8 starts to rotate reversely to drive the lifting hook 5 to lift the sand bag, and when the lifting hook 5 rises above the sand tank component 1, the motor drives the self-propelled trolley component 2 to move in the I-shaped steel slide rail 11 to the position right above the sand tank component 1. After the sand reaches the designated position, the winch 8 rotates forwards, the sand bag descends to the top of the sand tank and contacts with the sand breaker, so that the sand bag is broken, sand is added into the sand tank, and the sand adding is completed. After the sand is added, the winch 8 works, and the lifting hook 5 returns to the lifting position; then the motor drives the self-propelled trolley component 2 to move in the I-shaped steel slide rail 11 to the outside of the sand tank component 1, and the lifting hook 5 falls down to carry out the next sand adding work.

When the sand tank lifting device is used, the sand bag reaches the lifting point position of the sand tank along with the conveyor belt, and then the lifting assembly lifts the sand bag to break sand; can add sand jar suit according to the on-the-spot sand demand that adds.
