Technical field

The present invention relates to a kind of Manual fast tightening and clutch of water-cooled block, espespecially for fast tightening and the clutch of the girth joint cooling block of pipeline position automatic welding.

Background technology

When pipeline position automatic welding, under molten metal is easy, drops down and make appearance of weld poor, traditional welding method adopts minimizing welding current to guarantee welding quality, be prone to the defects such as lack of penetration, incomplete fusion, slag inclusion, the excessive defects such as burn at undercut, the back side, overlap that easily occur of welding current but welding current is too small, in thick-walled pipe all position welding termination process, backing welding technology is the key that guarantees welding quality, need veteran welder to use suitable welding procedure and strict technology, generally take copper lining in outside weld to force moulding root bead, need special to mouthpart, in band, copper lining is applied on a lot of pipelines abroad to the outer root bead moulding process of mouthpart, especially on submarine pipeline, application is more extensive, but this equipment volume is large, need exterior power equipment, and need at least two welders just can install and use, integer counterpart complex structure, installment and debugging uses inconvenient, affect welding efficiency.

High to mouthpart cost in order to overcome in existing band copper lining, volume is large, operation is used inconvenient, develop a kind of pipe lining water-cooled block fast tightening and clutch, do not need exterior power, simple in structure, installation and easy to repair, water-cooled block Manual fast tightening and clutch with low cost are the task of top priority.

Summary of the invention

Described in background technology, the object of the present invention is to provide a kind of water-cooled block fast tightening and clutch that does not need the power-equipments such as motor, hydraulic pressure and air pressure, only need a welder to pull mounting knob, slide plate is pulled to spring catch can easily be installed and used above, after welding, spring catch is recovered to pin frame inside, slide plate and water-cooled block pull recovery to get final product light clutch by extension spring, thereby realize Manual fast tightening and the clutch of the Manual fast tightening of pipeline internal groove root bead moulding water-cooled block and the pipeline automatic welding liner water-cooled block of clutch.

To achieve these goals, the present invention is achieved through technology:

A kind of water-cooled block Manual fast tightening and clutch, mainly by a fixed mount (1), two active guide rods (2), two driven guide rods (3), four handles (4), two bracing frames (5) and two slide plates (6) composition, wherein: initiatively guide rod (2) and driven guide rod (3) are arranged on fixed mount (1), adopt matched in clearance, axle bumper for both sides (33) is fixing, forms overall fixed bracket structure; Initiatively the upper and lower end parts of guide rod (2) is bolted with initiatively back-up ring (21), at the below of active back-up ring (21) suit active bracket slide block (22) and spring (23), and active bracket slide block (22) can slide along active guide rod (2), driven guide rod (3) upper, bottom is bolted with driven back-up ring (31), be set with driven bracket slide (32) in the side direction of driven back-up ring (31), and driven bracket slide (32) can be slided along driven guide rod (3); In the guide hole hole of slide plate (6), be fixedly mounted with slide plate slide block (61), slide plate (6) is sleeved on active guide rod (2), and can slide along active guide rod (2), four handles (4) are connected with slide plate (6) by bolt; Be bolted bracing frame (5) at the left and right sides of fixed mount (1), upper and lower side at bracing frame (5) is connected with spring catch frame (53) by dormant bolt (52), and wherein device has telescopic spring catch (51).

Owing to having adopted technique scheme, tool of the present invention has the following advantages and effect:

1, the present invention has adopted guide rod slide block mechanism, utilize the locked stretching of spring catch, the structures such as extension spring recovery clutch have realized Manual fast tightening and the clutch of water-cooled block, this mechanism structure is simple, only need a welder to use, do not need to introduce power-equipment, be particularly suitable for field and use, can be widely used in fast tightening and the clutch of moulding water-cooled block in the pressure of pipeline automatic welding root bead.

2, the present invention adopts Central Symmetry to arrange, the strict centering groove center, fluting position of water-cooled block while making fast tightening, thus guaranteeing root bead Forming Quality, this mechanism structure is simple, cheap, and working service and repairing are simple and easy.

The specific embodiment

Illustrated by Fig. 1 and Fig. 2, a kind of water-cooled block Manual fast tightening and clutch, mainly by 2, two driven guide rods 3 of 1, two active guide rod of a fixed mount, four handles 4, two bracing frames 5 and two slide plates 6 form, and wherein: initiatively guide rod 2 and driven guide rod 3 are arranged on fixed mount 1, adopt matched in clearance, both sides are fixing with axle bumper 33, form overall fixed bracket structure; Initiatively the upper and lower end parts of guide rod 2 is bolted with initiatively back-up ring 21, below active back-up ring 21, be set with active bracket slide block 22 and spring 23, and active bracket slide block 22 can slide along active guide rod 2, driven guide rod 3 upper, bottom is bolted with driven back-up ring 31, be set with driven bracket slide 32 in the side direction of driven back-up ring 31, and driven bracket slide 32 can be slided along driven guide rod 3; In the guide hole hole of slide plate 6, be fixedly mounted with slide plate slide block 61, slide plate 6 is sleeved on active guide rod 2, and can slide along active guide rod 2, and four handles 4 are connected with slide plate 6 by bolt; Be bolted bracing frame 5 at the left and right sides of fixed mount 1, be connected with spring catch frame 53 at the upper and lower side of bracing frame 5 by dormant bolt 52, wherein device has telescopic spring catch 51.

Referring to Fig. 3, when the present invention works, initiatively guide rod 2 presents and is arranged symmetrically with along center, and guide effect is played in stretching and clutch to upper and lower water-cooled block, driven guide rod 3 presents and is arranged symmetrically with along center, and stretching and clutch to left and right water-cooled block play guide effect, and initiatively the length of guide rod 2 and driven guide rod 3 changes with the thickness of internal diameter of the pipeline and water-cooled block, its length is generally less than internal diameter of the pipeline, and the internal diameter that should be more than or equal to water-cooled block adds the length of 2 times of water-cooled block thickness.

The course of work of the present invention is: welder's pull handle 4, slide plate 6 moves laterally along active guide rod 2, spring 23 is compressed, in the time that slide plate 6 moves to spring catch 51 top, spring catch 51 ejects, and mechanism is locked, and upper and lower water-cooled block is by stretching, simultaneously drive left and right water-cooled block along the driven guide rod 3 whole mechanism of mobile stretching laterally by upper and lower water-cooled block, the fast general structure schematic diagram of stretching water-cooled as shown in Figure 3; Clutch process is that after spring catch 51 is regained, slide block and water-cooled block pull recovery to get final product light clutch (Fig. 3 is referred in extension spring installation site) by extension spring.

Separately know, four handles 4 bolts are connected on slide plate 6, move up and down with slide plate.

In order to guarantee that the moving component on guide rod slides smoothly, initiatively support slipper 22, driven support slipper 32 and slide plate slide block 61 are red copper material.

Know, in order to guarantee root bead Forming Quality, this mechanism presents Central Symmetry along fixed mount 1 and arranges, the strict centering groove center, fluting position of water-cooled block while making fast tightening again.
