SUMMERY OF THE UTILITY MODEL

In view of the above problem, the utility model provides a quick off-load formula sand section of thick bamboo support has solved the difficult problem of cleaing away of grit in the sand section of thick bamboo.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a quick off-load formula sand cylinder support, includes the urceolus, sets up the inner tube in the urceolus and sets up the bottom plate under the urceolus, inner tube upper portion is equipped with the cushion, the urceolus bottom is equipped with the sand outlet of mutual symmetry, be equipped with adjusting device in the sand outlet, adjusting device includes the lead screw, the lead screw both ends all are equipped with the voussoir that runs through sand outlet both sides and mutual symmetry, the outside of voussoir be equipped with lead screw complex nut, the bottom surface of voussoir with the bottom surface of urceolus is tangent, and tangent partial urceolus bottom surface is equipped with and runs through the sand leakage mouth outside the bottom plate.

Preferably, the outer wall of the inner cylinder is tangent to the inner wall of the outer cylinder.

Preferably, the cushion block is square, and the side length of the cushion block is larger than the diameter of the outer barrel.

Preferably, the wedge block is provided with a through hole for the lead screw to pass through.

The utility model has the advantages that: the utility model provides a pair of quick off-load formula sand section of thick bamboo support utilizes the mobility of grit, adopts a sand section of thick bamboo to replace hydraulic jack, need not adjust the backing plate of jack repeatedly and change the jack, and simple structure, small investment, workable can design to the weight of steel structure and the requirement of falling height, have solved the support problem that the steel structure is safe, swift, steady, evenly descends to take one's place. The adjusting device is arranged to control the sand outlet amount of the sand outlet and the sand leakage port, so that sand in the outer barrel can be quickly discharged, the purpose of quick unloading is achieved, and the working efficiency is improved.

Wherein: 1. the sand-leakage-prevention device comprises an outer cylinder, 2, an inner cylinder, 3, a bottom plate, 4, a cushion block, 5, a sand outlet, 6, an adjusting device, 7, a screw rod, 8, a wedge block, 9, a nut, 10 and a sand leakage opening.

Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

For convenience of description, the words "upper", "lower", "left" and "right" in the present application, if any, merely indicate that the directions of movement of the device or element are consistent with those of the drawings, and do not limit the structure, but merely facilitate the description of the invention and simplify the description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the invention.

As shown in fig. 1-2, a quick unloading type sand cylinder support comprises an outer cylinder 1, an inner cylinder 2 arranged in the outer cylinder 1 and a bottom plate 3 arranged below the outer cylinder 1, wherein the outer wall of the inner cylinder 2 is tangent to the inner wall of the outer cylinder 1, a cushion block 4 is arranged on the upper portion of the inner cylinder 2, the cushion block 4 is square, the side length of the cushion block is larger than the diameter of the outer cylinder 1, sand outlets 5 which are symmetrical to each other are arranged at the bottom end of the outer cylinder 1, an adjusting device 6 is arranged in each sand outlet 5, the adjusting device 6 comprises a lead screw 7, wedge blocks 8 which penetrate through two sides of each sand outlet 5 and are symmetrical to each other are arranged at two ends of each lead screw 7, through holes through which the lead screws 7 penetrate are arranged on the wedge blocks 8, nuts 9 which are matched with the lead screws 7 are arranged on the outer side of the wedge blocks 8, the bottom surface of the wedge blocks 8 is tangent to the bottom surface of the outer cylinder 1, and a sand leakage port 10 which penetrates through the bottom plate 3 is arranged at the tangent part of the bottom plate 1, the number of the sand leakage openings 10 is 2.
