Abstract

The invention discloses a clamp tool for installing a bell-spigot type nodular cast iron pipe. The clamp tool comprises a clamp A and a clamp B. The clamp A and the clamp B are each provided with a clamp arm used for clamping pipelines and an arc-shaped hoop arranged on the clamp arm and used for holding the pipelines, wherein the arc-shaped hoop is located on the side, facing the pipelines, of the clamp arm. Tensioning lead screws are arranged between the portions, located on the same side, of the clamp arm of the clamp A and the clamp arm of the clamp B, penetrate through the clamp arms, and are parallel to the ground. A thrust nut is arranged at each of the two ends of each tensioning lead screw, located at the outer side of the corresponding clamp arm and matched with the tensioning lead screw. The clamp arm of the clamp A and the clamp arm of the clamp B are clamped on the two sides of the two oppositely arranged pipelines, and the thrust nuts are rotated to move towards the middle, so that the clamp at one side of the thrust nuts is pushed to move along with the thrust nuts. The clamp tool has the advantages of being simple in structure, convenient to operate, capable of assembling two pipelines quickly, and low in installation cost.

Description

A kind of clamp fixture for installing spigot-and-socket ductile iron pipe

Technical field

The present invention relates to a kind of pipeline installation engineering field, particularly a kind of fixture work for installing spigot-and-socket ductile iron pipe Dress.

Background technology

In China's construction project, the commonly used socket joint ductile iron pipe of current water supply and sewage work, when mounted, spheroidal graphite casting Iron pipe is usually mounted to underground, and installation site is deeper, and pipe trench is also narrow, causes installation operation scope little, and Jing can only often be adopted Coordinated with Miniature digging machine and installed.However, the labour cost of digging machine is higher, and device is cumbersome, fully relies on operator Jing Test with feel to transfer ductile iron pipe, it is relatively time-consuming.

Except using above-mentioned digging machine mode come, in addition to installing, during actual installation, also Jing pulls calabash frequently with traditional Reed, is lifted by chain block forms a team to be respectively fitted on two relative ductile iron pipes.Although which solves Relatively costly problem, but the efficiency or relatively low, the high labor intensive of workman of its installation.

The content of the invention

The invention aims to solve low existing means lifting spheroidal graphite cast-iron tube efficiency, high labor intensive, into This higher problem, and a kind of clamp fixture of the installation spigot-and-socket ductile iron pipe for providing.

To achieve these goals, the clamp fixture of a kind of installation spigot-and-socket ductile iron pipe designed by the present invention, it Including fixture A and fixture B, the fixture A and fixture B includes being used in combination for clamping the jig arm of pipeline and being arranged in jig arm In the arc anchor ear for holding pipeline tightly；The jig arm of the fixture A and fixture B is constituted by the support arm that two rotary types connect, described Arc anchor ear is located at jig arm towards the side of pipeline；Be provided between fixture A and fixture B homonymy jig arm one through jig arm and with The horizontal tension screw mandrel in ground；One is equipped with the outside of the two ends of tension screw mandrel, jig arm to be engaged with screw mandrel is tensed Push nut, by the jig arm in fixture A and fixture B is clamped in two pipeline both sides being oppositely arranged respectively, and rotate Nut is pushed, the rotated backward middle part movement of nut is pushed, so as to promote the fixture in its side to move.

Further, for the ease of adjusting the spacing in fixture A and fixture B between two support arms, adapt to the folder of different tube diameters Hold, meanwhile, be easy to fixture A, fixture B with the installation and removal between cast-iron pipe, one is provided with for adjusting in two support arm upper ends The clamp system of spacing between section support arm, the clamp system include the clamping silk on a turnable support arm installed therein Bar, the screw mandrel being fixedly mounted on another support arm are placed block and are located at and clamp screw mandrel placement block both sides and be enclosed within clamping screw mandrel Adjusting nut, during use, rotating adjusting nut, you can drive that the screw mandrel in its side places block and to place block with screw mandrel solid The support arm displacement of fixed connection.

Further, screw mandrel place block upper end be provided with one for place clamping screw mandrel breach, the breach can be so as to Depart from screw mandrel placement block in placing to clamp screw mandrel or screw mandrel will be clamped, change the adjusting nut being easily damaged.

Further, the support arm is by upper arm, underarm and is placed in linking arm between upper arm and underarm and oblique Composition, the linking arm in two in fixture A and fixture B support arm are cross-shaped, are provided with a rotary shaft in linking arm intersection. Arranged in turnable structure by the support arm by fixture A and fixture B, two support arms can be connected into an entirety, together When, it is easy to two arm rooms to rotate, adjusts the spacing of two arm rooms.

Further, the clamp system is arranged between fixture A and the upper arm of fixture B each support arm, and the arc is embraced Hoop is on the underarm of fixture A and fixture B each support arm, and the radian of arc anchor ear is outer with cast-iron pipe in each fixture Wall radian is identical.

Compared with prior art, a kind of clamp fixture of installation spigot-and-socket ductile iron pipe that the present invention is obtained has as follows Advantage：

1st, by being clamped on two pipelines to be installed respectively using two fixtures, and wear in the jig arm of two fixtures A piece horizontal tension screw mandrel, by push nut of the rotary sleeve on screw mandrel and on the outside of jig arm, you can drive and the spiral shell The adjacent fixture of parent phase and pipeline are mobile to centre together, so that two pipelines connect together.

2nd, it is fitted with for adjusting two clamp systems for intersecting spacing between support arms, the clamp system on each fixture Corresponding spacing between two support arms can be adjusted according to the external diameter size of field pipes, so as to realize the purpose of clamping pipe.

3rd, the structure of fixture is relatively simple, easy for installation, only needs a people i.e. operable during installation, save it is artificial and into This.Meanwhile, during operative, only need the spacing in installs fixture, alignment jig between support arm and rotation to push nut, It is time saving and energy saving.
