Problems solved by technology

In the prior art, spectacle plates are relatively easy to wear due to their special working conditions. Therefore, steel plates are usually used as the substrate, and then hard alloys are inlaid on the working surface and wear-resistant welding rods are surfacing for production. The defects of this scheme The cemented carbide has a high cost, high brittleness, and is easy to crack during work; at the same time, the cemented carbide is connected to the substrate through brazing, and if the brazing quality is not good enough, it is easy to cause the cemented carbide to fall off
In addition, the spectacle plates in the prior art are heavy and inconvenient to maintain

Embodiment Construction

[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0035] see Figure 1 to Figure 9 According to one aspect of the present invention, a wear-resistant ring assembly is provided, including a base body 1 and a wear-resistant ring 2 fixedly connected to the base body 1, the base body 1 has a feeding hole 3 and a groove 4 around the feeding hole 3 , wherein the wear ring 2 is fixed to the groove portion 4 by a fastener 5 . Preferably, the substrate 1 is a light alloy, such as aluminum alloy, magnesium alloy, titanium alloy, etc., and the wear-resistant ring 2 is a ceramic material, such as alumina, zirconia, boron carbide, and the like.

[0036] As mentioned above, since the wear-resistant ring 2 is fixed to the g...

Abstract

The invention discloses a wear-resistant ring assembly, comprising a base body (1) and a wear-resistant ring (2) fixedly connected to the base body (1), the base body (1) has a feeding hole (3) and a The groove portion (4) around the feeding hole (3) is characterized in that the wear-resistant ring (2) is fixed to the groove portion (4) by a fastener (5). In addition, the invention also discloses a pumping device. Since the wear-resistant ring is fixed to the groove of the base body through the fastener, the problem that the wear-resistant ring is easy to fall off is solved, and the connection reliability is stronger.

Description

technical field [0001] The invention relates to the field of concrete delivery pumps, in particular to a wear-resistant ring assembly and pumping equipment including the wear-resistant ring assembly. Background technique [0002] As a wear-resistant ring component, the spectacle plate is also called a wear-resistant plate. It is an important part of the concrete pump. It forms a matching friction pair with the cutting ring. The cutting ring is installed on the swing end of the S pipe, and through the swing cylinder Function, the S tube drives the cutting ring to slide back and forth on the spectacle plate to realize the alternate pumping of the double cylinders. In the prior art, spectacle plates are relatively easy to wear due to their special working conditions. Therefore, steel plates are usually used as the substrate, and then hard alloys are inlaid on the working surface and wear-resistant welding rods are surfacing for production. The defects of this scheme The reason...
