The invention discloses a supporting rod spring assembling device and belongs to the field of supporting rod spring assembling equipment. The supporting rod spring assembling device comprises a slide rail line, an outer sleeve positioning part, spring keeping parts and a spring compressing part, wherein the outer sleeve positioning part, the spring keeping parts and the spring compressing part are sequentially arranged along the slide rail line from front to back, and the spring compressing part and the outer sleeve positioning part are both arranged on the slide rail line in a sliding manner; the outer sleeve positioning part comprises a positioning sliding plate and an outer sleeve clamping base arranged on the positioning sliding plate; the spring keeping parts are sequentially arranged along the slide rail line, and two keeping mechanisms of each spring keeping part are arranged above the slide rail line relative to the mirror image of the slide rail line; and the spring compressing part comprises a driving sliding plate, a shifting plate and a spring sleeve clamping base, and the shifting plate and the spring sleeve clamping base are sequentially arranged on the driving sliding plate from front to back. It is guaranteed that no deformation is generated in the spring assembling process, friction collision between the spring and other parts is avoided, the assembling time is shortened, the assembling efficiency is improved, the automation degree is high, and the supporting rod spring assembling device can adapt to supporting rods in different length specifications.

The invention relates to the technical field of assembling a large prefabricated member, and particularly relates to a prefabricated concrete octagonal column assembling device and discloses an assembling method of a prefabricated concrete octagonal column. The assembling method comprises the following steps: a. setting up a measurement control frame at the outer periphery of an octagonal column embedded part; b. setting up a support frame connected with a scaffold; c. prefabricating the prefabricated concrete octagonal column; d. hoisting the prefabricated concrete octagonal column; and e. controlling the perpendicularity of the prefabricated concrete octagonal column. The problem that the centrifugal prefabricated concrete column cannot be embedded and hoisted can be effectively solved, and a clasp and foot pads can be repeatedly utilized; and the use amount of cranes can be saved, the site limiting problem for positioning cables can be avoided, the hoisting accuracy can be improved, the problem existing in traditional construction can be effectively solved, the assembling efficiency can be improved, the construction period can be shortened, and the construction cost can be saved.

The invention belongs to the field of automobile connecting pieces, specifically relates to an anti-stripping pipe clamp. The anti-stripping pipe clamp comprises a nip used for clamping pipe fittings. The other side of the nip relative to a clamping interface used for clamping pipe fittings is reversely provided with inserting columns orderly. Each inserting column is distributed with right tapered through holes penetrating the inserting column. The through holes form a hollow expansive sleeve structure of the inserting column, and the inserting columns and automobile fixing pieces form an inserting type expansive nail match. The pipe clamp also comprises expansive pins used for forming an inserting match with the inserting columns which are in a shape of an expansive sleeve. The inserting ends of the expansive pins are forwardly provided with sheltering sections orderly along the axes. The sheltering sections and the top ends of the inserting columns form a unidirectional sheltering match. The separation distances of the sheltering sections on the expansive pins and the inserting ends are greater than or equal to the lengths of the through holes. The unidirectional stop performance is realized after the expansive pins are inserted in the inserting columns by arranging the sheltering sections at the inserting ends of the expansive pins, so that the storage and transportation cost of the pipe clamp is obviously reduced, and meanwhile the self-working performance of the pipe clamp is maintained.
