The utility model provides a kind of long pipe to solve the problems, such as that long pipe support positioning makes welding quality improve Retaining wall on slope positioning device.

The utility model is achieved by the following technical solution：A kind of long pipe retaining wall on slope positioning device, it is special Sign is：Including one block of plectane, the circle centre position of the plectane is fixed there are one cylindrical cushion block, is connected by bearing on the cushion block It connects there are one center taper shank, is uniformly distributed on peripheries with four fixed seats centered on cushion block on the plectane, each fixed seat includes axis Seat and two pieces of gussets with plectane diameter symmetry, the gusset are fixed on plectane, and the axle bed is welded between two pieces of gussets, A leading screw is connected between two axle beds, the leading screw both ends are respectively arranged in by thrust ball bearing on two axle beds；Institute It states and is threaded with nut on leading screw, top plate is fixedly welded on the nut, the top plate is located at the oval hole slot on plectane It is interior, and stretch out oval hole slot.

The utility model is to fix more difficult and design in lathe process groove for long pipe, and the device is with circle Plate is substrate, is opened on plectane there are four oval hole slot, and four oval hole slots are distributed in centered on the plectane center of circle on plectane, It is respectively equipped with fixed seat positioned at the position of four oval hole slots（As shown in Fig. 2, being that respectively there are one fixed seats up and down）, often A fixed seat includes two pieces of gussets, and two pieces of gussets are fixed on plectane with the diameter symmetry of plectane, are played a supportive role；It is oval Top plate in hole slot is used for fixing and supporting long pipe, and top plate is fixed on nut, and nut is connect with threads of lead screw, can pass through rotation Stubborn leading screw comes the position of adjusting nut and top plate, adapts to taking over for different-diameter with this, leading screw is installed by thrust ball bearing In on two axle beds, two axle beds are fixedly connected on two pieces of gussets；It fixes positioned at the circle centre position of plectane and is padded there are one cylindrical Block is connected with center taper shank on the cushion block by bearing, and the effect of center taper shank is for insertion on the tailstock of lathe, when whole When a device rotation, which is fixed.The utility model concrete operations are：By the center in the positioning device Taper shank is inserted on tail stock, and long pipe is then stuck in four top plates outsides or inside, if long pipe is relatively large in diameter, Then top plate is stuck in long pipe, if diameter is smaller, top plate may be stuck in long pipe or on the outside of long pipe；And pass through Leading screw is screwed to adjust the position of top plate and nut so that top plate is by long pipe clamping and supports fixation, is completed when support is fixed Afterwards, you can carry out retaining wall on slope.

Preferably, in order to be suitable for taking over for more sizes, plectane can suitably be done to larger, the diameter of the plectane For 500mm.

Preferably, in order to make take over uniform force and support it is more secured, top plate is longer at a distance from take over contact, because The length that this described top plate stretches out oval hole slot is 30-60mm.

Preferably, screwing in order to facilitate leading screw, one end end face that the leading screw stretches out axle bed are square.

The utility model has the advantages that compared with prior art：The utility model traditional groove before solving The problem of processing, the apparatus structure is simple, easy to operate；Manual polishing groove cost is not only saved, while improving long pipe Welding quality；It improves work efficiency, saves human and material resources, financial resources, be fixed on tailstock tool by center taper shank, so Carry out retaining wall on slope again afterwards.
