Detailed ways

The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Fig. 1, the longitudinal beam driving structure used for grate cooler material delivery includes a crossbeam 1 and a driving beam 7 arranged longitudinally above the crossbeam, and the crossbeam 1 is provided with support wheels 8 for supporting the driving beam and The hydraulic drive structure is based on the movement of the traction drive beam. The hydraulic drive structure includes two drive hydraulic cylinders and 4 or more drive hydraulic cylinders. Each drive beam is driven by at least two drive hydraulic cylinders, and each drive hydraulic cylinder is driven by a fixed base. Set on beam 1.

The support wheels 8 are arranged in two or more groups vertically; the support wheels are arranged in two or more groups horizontally to support two or more rows of drive beams 7; the longitudinal and transverse support wheels form a support surface to support a group of drive beams , thus supporting a larger grate bed.

The drive hydraulic cylinders are arranged in two or more groups vertically; the drive hydraulic cylinders are arranged in two or more groups horizontally to drive two or more rows of drive beams; all the arranged drive hydraulic cylinders are combined to form an integral drive module. The module drives the entire grate bed, and the grate bed can do cyclical reciprocating motion under the action of the driving structure, and the operation is stable and reliable.

The fixed base 2 is arranged on the beam through a detachable structure, and the fixed base is located directly below the driving beam. Preferably, the fixed base includes an upper base and a lower base, the upper base and the lower base are clamped and fixed on the beam, and the upper base and the lower base are connected and fixed on the beam by fixing bolts 3, which is easy to install and disassemble.

The bottom of the driving beam is provided with an ear seat, and the rod head 5 at one end of the driving hydraulic cylinder 4 is hinged on the fixed base through the pin shaft 6, and the other end rod head of the driving hydraulic cylinder is hingedly connected with the ear seat through the pin shaft, which is easy to connect.

There is a buffer structure 9 between the piston end of the driving hydraulic cylinder and the cylinder body of the driving hydraulic cylinder. The buffer structure can be a coil spring structure, which is sleeved at the end of the piston rod to prevent the hydraulic cylinder from hitting the cylinder end during operation. The drive runs smoothly and reliably.

The two driving hydraulic cylinders corresponding to each row of driving beams have opposite structural arrangements, and one driving hydraulic cylinder works in a rodless chamber while the other driving hydraulic cylinder works in a rod chamber.

At least two hydraulic cylinders are installed on each row of drive beams. When the drive beam is moving forward or backward, two hydraulic cylinders are used to work at the same time. The auxiliary hydraulic cylinder works with a rod cavity. When the driving beam is retreating, the two hydraulic cylinders work in the opposite way. This operation mode can reduce the working pressure, volume and weight of a single hydraulic cylinder, which is convenient for installation and removal, and makes the whole hydraulic system run smoothly.

Combined with a special structure, the hydraulic system has small operating resistance, the entire hydraulic system runs smoothly, the seal is not easy to damage, oil leakage, the hydraulic cylinder is small in volume and weight, easy to install and disassemble, low in cost, and reliable in operation.
