[0002] The railway open wagon needs to be clamped and fixed after entering the dumper body, and the clamping device comprises a car pressing device and a car leaning device. The car pressing device is the main clamping device, which is used for pressing the railway open wagon to prevent the railway open wagon from loosening and causing derailment accidents during the dumping process, and the spring force of the railway open wagon needs to be released during the dumping process to prevent damage to the railway open wagon.
[0003] The existing dumper car pressing device is divided into balanced beam type and through beam type, and the spring force release compensation method is divided into hydraulic system release compensation and external elastic device release compensation.

In order to meet the requirements of high car type dumping, the size of the dumper needs to be increased, and the equipment manufacturing cost is high. The through beam type car pressing device is hinged to the front and rear beams on both sides of the dumper, and swings around the hinge point. When pressing different types of railway open wagons, due to the height difference of the railway open wagons, the pressing plane is affected by the swing angle and forms an angle with the upper plane of the railway open wagon, the pressing plane is not in good contact, and a thrust is generated on the side of the railway open wagon, which is easy to cause the vehicle to loosen and damage.
