Description

GLASS PLATE FOR A CONCRETE CONVEYING PUMP FIELD OF THE INVENTION
[0001] The present invention relates to a glass plate for a concrete conveying pump. DESCRIPTION OF THE PRIOR ART
[0002] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
[0003] Existing glass plates for concrete conveying pumps comprise a steel base with two feeding through holes thereon, the end face of the steel base is embedded and welded with a wear-resistant material slide joint surface, and shear rings are assembled in the two feeding through holes of the steel base. In the Chinese Patent Authorized Publication No. CN201582092 U, shear rings are assembled in two feeding through holes of the steel base, one end of each shear ring is provided with a flange ring that is accommodated in a countersunk hole of the steel base. During use, the flange ring is pressed tightly in the countersunk hole by the assembly pressure between the steel base and the external conveying pump such that the shear ring will not become loose or turn and fall off in operations. On some steel bases, however, interference could take place between the countersunk holes for accommodating the shear rings and sealing grooves on the end face thereof. Moreover, the assembly and disassembly thereof are relatively inconvenient. In addition, such a sear ring only has one face thereof utilized, which is a waste.
SUMMARY OF THE INVENTION
[0004] Advantageously, the aim of at least one preferred embodiment of the present invention is to provide a glass plate for a concrete conveying pump, eliminate countersunk holes for accommodating the shear rings and a flange ring at one end of each shear ring, avoid the interference of sealing grooves on the end face of the steel base and the countersunk holes for accommodating the shear rings thereon, and achieve convenient assembly and disassembly.
[0005] The glass plate for a concrete conveying pump according to the present invention comprises a steel base with two feeding through holes thereon, the end face of the steel base is embedded and welded with a wear-resistant material slide joint surface, shear rings are assembled in the two feeding through holes of the steel base, which are provided with openings, grooves are formed on inner circular faces of the feeding through holes, and outer circular faces of the shear rings are provided with flanges matched with the grooves.
[0006] With the structure according to the present invention, the flange ring on the shear ring is eliminated and the interference of sealing grooves on the end face of the steel base and the countersunk holes for accommodating the shear rings thereon is avoided, leading to convenient assembly and disassembly. At the same time, the engagement of the grooves and the flange can effectively prevent displacement of the shear ring along the axial direction of the feeding through hole.
[0007] Along the axial direction, a centrally dividing plane of the shear ring is taken as a symmetry plane, and the grooves and the flanges are symmetrically arranged with respect to the symmetry plane.
[0008] With such a structure, the front of shear ring can be reversed to become the back, which is re-assembled in the feeding through hole for use, i.e. two end faces of the shear ring can be utilized, which doubles the service life of the shear ring relative to the past.
[0009] In such a structure, the structure of grooves and flange is simple, which facilitates design, processing and production.
[0010] The groove comprises at least one groove arc segment in the circumferential direction, the flange matches the groove and comprises the same number of flange arc segments as that of the groove arc segments.
[0011] Such a structure replaces continuous grooves and flanges with discontinuous grooves and flanges, which can prevent the shearing ring from turning circumferentially.
[0012] The cross-sectional shape of the grooves and flanges is rectangular, which can improve the precision of axial positioning of the shearing ring.
[0013] An expansion device is provided at the opening of the shearing ring.
[0014] When the shearing ring is placed in the feeding through hole, the expansion of the expansion device increases the diameter of the shearing ring such that the shearing ring is more reliably pressed tight onto the inner wall of the feeding through hole, which ensures that the shearing ring will not become loose during operations.
[0015] The expansion device is composed of two mutually matching expansion wedge blocks, and two side surfaces of the two expansion wedge blocks that match with the shearing ring are both parallel to the axis of the shearing ring.
[0016] With such a structure, when the shearing ring is reversed and installed on the feeding through hole, the two expansion wedge blocks can still match with the opening of the shearing ring such that the shearing ring with the expansion device can also be used twice with its front and back.
[0017] The steel base is provided with radial holes that are open to the feeding through holes, a screw is provided within the radial hole, and a screw hole is formed on one of the expansion wedge blocks for threaded connection with the screw.
[0018] The above structure can ensure that the shearing ring will not turn during operations and at the same time, is favorable for assembly and disassembly of the expansion wedge blocks.
[0019] The steel base is provided with a guide lifting groove that is open to the feeding through hole, and a guide ear that matches with the guide lifting groove is provided on one of the expansion wedge blocks.
[0020] During operations, the guide lifting groove can limit the circumferential position of the expansion wedge block by means of the guide ear therein, thereby ensuring that the shearing ring will not turn during operations.
[0021] The steel base is provided with radial holes that are open to the feeding through holes, a screw is provided within the radial hole for fixing the shearing ring, thereby ensuring that the shearing ring will not turn during operations.
[0022] Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise”, “comprising”, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to”.
