Abstract

PURPOSE:To secure the uniform abrasion of the inner surface of a tube and improve the durability of the tube by installing a transmission mechanism for turning hollow supporting members in the reverse directions, between a rotary body and the hollow supporting member. CONSTITUTION:The sleeves for the hollow supporting members 6 and 7 made of metal is fitting-fixed at the both edge parts of a tube 3. An annular part of the hollow supporting member is fitted into an annular recessed part formed by the edge plate 10 of a pump case 2 and holding rings 11 and 12 fixed onto the edge plate 10, in turnable manners through a bearing. Further, worm wheels 13 and 14 are fixed onto the hollow supporting members 16 and 17. When a rotatable body 4 is revolved by operating a driving device, the rotary body 4 revolves the hollow supporting members 6 and 7 in the reverse direction at an equal speed through driving chain wheels 22 and 23, transmission chains 29 and 31, trailing chain wheels 28 and 30, and worm and worm wheels 13 and 14. Thus, the tube 3 is turned by the turn of the hollow supporting members 6 and 7.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pump for transferring concrete having a tube rotation device used for transferring highly concentrated fluids such as concrete and mortar. [Conventional technology] Conventionally, as a pump for transferring concrete,
As disclosed in Publication No. 4-16141, a U-shaped tube made of an elastic material is disposed within a pump case having a semi-cylindrical portion and having a semi-circular portion extending along the circumference of the semi-cylindrical portion. There is known a structure in which a tube holding roller is attached around a rotating body provided in the center of the pump case. [Problems to be Solved by the Invention] In the case of the conventional concrete transfer bomb, the tube containing concrete is strongly compressed by the tube press roller, and both sides of the inner surface of the tube in the compression direction are compressed by the concrete. Since the tube is strongly pressed, wear concentrates on both sides of the inner surface of the tube in the compression direction, which causes the problem that the tube must be replaced at an early stage.
