Abstract

The invention discloses an abrasion-resistant plate of a concrete pump. A first hole and a second hole are formed in a body, an abrasion-resistant sleeve is embedded in the first hole, an abrasion-resistant sleeve is embedded in the second hole, a groove is formed in the abrasion-resistant face of the body, and a hard alloy layer is brazed in the groove. The invention further provides the concrete pump, and a manufacturing method of the abrasion-resistant plate of the concrete pump. According to the concrete pump, the abrasion-resistant plate of the concrete pump, and the manufacturing method of the abrasion-resistant plate of the concrete pump, surfacing of a flow channel is eliminated, and the problems that the abrasion-resistant plate is irregular in shape, heating is not uniform, and the deformation amount is large are avoided. The abrasion resistance and the sealing performance of the abrasion-resistant plate are improved, and the service life of the abrasion-resistant plate is prolonged.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a spectacle plate for a concrete pump and a manufacturing method. Background technique [0002] The spectacle plate and cutting ring are the wear-resistant parts of the concrete pump and also the key vulnerable parts of the concrete pump. The spectacle plate is installed on the rear wall of the hopper, and there are generally two inner holes on it, which are respectively connected to the delivery cylinder; The cutting ring is installed on the S valve, which has an inner hole. During the pumping operation, the S valve swings, and the inner hole of the cutting ring communicates with the inner hole of the spectacle plate alternately. During the pumping process, the spectacle plate and the cutting ring are subjected to large friction and impact forces, and their wear resistance, sealing performance and service life have always been important indicators that affect the overall qu...
