Abstract
The utility model provides a wear plate for a concrete pump, which comprises a wear plate body, wherein two through-holes are formed on the wear plate body; at least one cemented carbide wear ring is melt-cast on the inner ring-shaped surfaces of the through-holes of the wear plate body; and a cemented carbide wear layer is melt-cast on the end surface of the wear plate body. By combining the wear layer and a steel substrate into a metallurgical joint, the wear plate of the utility model is obviously superior to the products in the prior art in the aspects of shearing resistance, shock resistance and wear resistance; and the wear plate of the utility model has the advantages of reasonable structure, good shearing resistance, good shock resistance, good wear resistance and long service life. Therefore, the utility model is suitable for industrialized production; and the utility model can substitute for the existing wear plate for the concrete pump.
Description
Technical field
The utility model relates to concrete conveying equipment, and refering in particular to is a kind of glasses board for concrete pump, belongs to engineering machinery concrete conveying equipment technical field.
Background technology
Concrete pump has two plunger shaft with concrete hopper UNICOM usually, the S that is called first piston chamber, second plunger shaft and is arranged in the concrete hopper manages, described S manages an end and is connected with the concrete delivery pipe of peripheral hardware, the other end chronologically respectively with described first piston chamber, the second plunger shaft UNICOM, realize concrete conveying.Its course of work is: when S manages an end and first piston chamber UNICOM, with the hydraulic piston forward acting of this plunger shaft UNICOM, concrete is released plunger shaft, enter the peripheral hardware concrete delivery pipe through the S pipe, realize concrete conveying; Meanwhile, oppositely do work with the hydraulic piston of the second plunger shaft UNICOM, in the concrete inspiration corresponding piston chamber in the concrete hopper, when the forward acting was finished in the first piston chamber, the S pipe was rocked to the second plunger shaft end, and with the second plunger shaft UNICOM, equally, with the hydraulic piston forward acting of this plunger shaft UNICOM, concrete is released plunger shaft, enter the peripheral hardware concrete delivery pipe through the S pipe, realize concrete conveying; And so forth, realize concrete continuous conveying.Because S tube end and first piston chamber, the second plunger shaft end are in the state of reciprocatingly sliding, therefore, wearing and tearing easily between the contact-making surface cause vacuum reduction in the concrete delivery pipe road, influence the concrete continuous delivery reliability; Prior art is in order to overcome this defective, normally in the first piston chamber, the equipped cheater plate in the second plunger shaft end, described cheater plate is provided with two through holes that mate with described first piston chamber, second plunger shaft, in end face soldering one deck hard alloy abrasion-resistant layer of cheater plate, the wear-resisting circle of rich chromium cast iron is enclosed in built-up welding one respectively on two through hole inner peripherys of cheater plate; The improvement of this structure, raising first piston chamber, the wearability of the second plunger shaft end that can part prolong the service life of cheater plate, improve the concrete continuous delivery reliability; But, this structure in use, still there is following defective: at first, because the rich chromium cast iron impact wear resistance is lower, in actual use, the wear-resisting circle of rich chromium cast iron of the inner periphery setting of cheater plate is easy to be lost efficacy by the concrete impact wear, causes the cheater plate inner periphery to form edge of a knife shape; Secondly, the hard alloy layer of cheater plate end face soldering, because the shear strength of soldering weld layer is lower, therefore, when the edge of a knife shape of cheater plate end inner periphery formation feeds through to the soldering weld layer, the hard alloy layer of soldering will be easy to be come off by impact grinding; In addition,, reduce faulty soldered joint, require bonding area less usually in order to improve the firm welding degree of carbide ring and cheater plate end, thereby, limited the area of soldering at the hard alloy layer of cheater plate end face, cause its wearability increase rate less.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of rational in infrastructure, and anti-cutting performance, shock-resistant polishing machine are good, the glasses board for concrete pump of long service life.
A kind of glasses board for concrete pump of the utility model is to adopt following proposal to realize:
A kind of glasses board for concrete pump, comprise the cheater plate body, described cheater plate body is provided with two through holes, on the through hole inner ring surface that described cheater plate body is provided with, founding has at least one circle carbide alloy wear ring, and founding has hard alloy abrasion-resistant layer on described cheater plate body end face.
In the utility model, on the described through hole inner ring surface on the carbide alloy wear ring of founding and the described cheater plate body end face hard alloy abrasion-resistant layer of founding connect as one.
The utility model is owing to adopt said structure, and direct founding hard alloy abrasion-resistant layer on cheater plate body surface and through hole inner ring surface compared with prior art, has the following advantages:
Since directly employing carbide alloy founding at cheater plate body surface and through hole inner ring surface as wearing layer, therefore, wearing layer is the combination of metallurgical interface with combining of steel matrix, raising greatly when its bond strength, anti-cutting performance, shock resistance are compound to the steel matrix surface than the employing soldering with carbide alloy, thereby, effectively improve the life-span that cheater plate is on active service under bad working environments; In addition, the impact wear resistance of carbide alloy is than rich chromium cast iron height, therefore, significantly improve than prior art at substrate combinating strength, also than under the good situation of prior art, anti-cutting performance of the present utility model, shock resistance, abrasion resistance properties all obviously are better than the product that prior art is produced to the performance of wearing layer own, contrast through overtesting, service life, the pump concrete amount of the utility model on concrete pump compared with the product that prior art is produced, and all reaches more than 3 times.
In sum, the utility model is rational in infrastructure, and anti-cutting performance, shock-resistant polishing machine are good, and long service life is suitable for suitability for industrialized production, alternative existing concrete delivery pump cheater plate.
