The specific embodiment
The structure that Figure of description illustrates, ratio, size etc., equal contents in order to cooperate specification to disclose only, equal contents in order to cooperate specification to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the present invention, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this specification as " on ", the term such as D score, 'fornt', 'back', " centre ", also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
Fig. 1 is the structural representation of flange butt joint auxiliary device.Can see that by schematic diagram an end of hydraulic clamp clamp 2 is provided with fixedly backing plate 3, the other end is equipped with clamping cylinder 1, and the flange butt joint auxiliary device will be finished clamping work will two hydraulic clamp clamp 2 at least.Described hydraulic clamp clamp are C shapes herein, but all should drop in the claim protection domain as herein described with the similar project organization of C shape.For the overall weight that makes the flange butt joint auxiliary device light as far as possible, clamping cylinder 1 adopts built-in, be embedded in the hydraulic clamp clamp, can make like this total length of hydraulic clamp clamp 2 be reduced by at least 50mm, because described hydraulic clamp clamp 2 are C shapes, so have the uneven situation that affects work of local pressure, therefore, thinner destructible position increases certain thickness to guarantee bulk strength in the centre.Oil cylinder 1 is connected with Hydraulic Station 19.
Each hydraulic clamp clamp 2 is installed in the upper end of a support bar 20, connects hydraulic clamp clamp 2 and support bar 20 with a movable spring 4.Described movable spring 4 be have certain bending stiffness without guide spring, can be crooked to different directions, like this so that clamping device allows working face that certain angle is arranged when work, movable spring 4 can be tilted separately in allowed band, the maintenance level thereby the chassis that makes elevating mechanism and flange butt joint auxiliary device remains unchanged, and then also be convenient to contraction, adjustment support bar so that more stable work.
Passive every support bar 20 is fixed on the active section 12 of omnidirectional mechanism 14 outermost end, and support bar 20 is wrapped support arm 10 and lower branch arm 13, and lower branch arm 13 is connected on the hoistable platform 15 by the active section 12 on the omnidirectional mechanism 14.The upper branch arm 10 of support bar 20 and lower branch arm 13 is hinged by folding joint 11 so that the transportation of flange butt joint auxiliary device and when depositing can with two sections support arm folding shrinkings to general length to save the space.Outer surface cover at the folding joint 11 of hinged place has mobilizable locking bushing 9, and locking bushing 9 is fixed on two sections support arms on the same straight line when work.
Fig. 2 is the concrete structural scheme of mechanism of upper branch arm 10.Upper branch arm 10 comprises interior slide bar 5 and outer sliding sleeve 7, interior slide bar 5 be connected movable spring 4 and connect, outer sliding sleeve 7 is enclosed within the outside of interior slide bar 5, and interior slide bar 5 bottoms are sitting on the buffer spring 8 of outer sliding sleeve 7 inside, the effect of described buffer spring 8 is to allow the flange on top to clamp clamp to produce in the course of the work some displacements, can also avoid in addition operating personnel owing to neglect so that the unexpected shock of a fall equipment of clamping device, this is played cushioning effect, avoid interior slide bar 5 to slide easily for reaching when producing buffering effect, buffer spring 8 should adopt hard spring or the larger spring of rigidity.Be provided with set screw 6 at outer sliding sleeve 7, under flange butt joint auxiliary device duty, set screw 6 is in relaxed state, so that buffer spring 8 plays cushioning effect, under off working state, set screw 6 is in the state of screwing, and slides so that interior slide bar 5 can not produce with respect to outer sliding sleeve 7, has an accident in order to avoid interior slide bar 5 skids off.
The motion of flange butt joint auxiliary device can realize that by travelling car 18 dolly comprises pushing hands, chassis and four wheels, and two fast pulleys are in a side on chassis in the four wheels, and two other deflecting roller is fixed on opposite side.Electric hydraulic operating desk 17 and Hydraulic Station 19 and hoistable platform 15 all are installed on the dolly, electric hydraulic operating desk 17 and Hydraulic Station 19 are at the tail end of dolly, the bottom of hoistable platform 15 is provided with hoist cylinder 16, hoist cylinder 16 links to each other with Hydraulic Station 19 and is installed in the place ahead of Hydraulic Station 19, and described hoist cylinder 16 promotes the rough adjustment of the hoistable platform 15 realization flange butt joint auxiliary device height on the lifting support.One side of lifting support is installed on the rotatable hanging feet, and a side then is installed in the adjusting of the enterprising line height of slideway, and slideway and hanging feet are separately fixed on the chassis and the hoistable platform bottom.
Fig. 3 is that the installation of straight blowing pipe of blast furnace and reduced pipe concerns schematic diagram, can see the installation site of straight blowing pipe of blast furnace and reduced pipe and the position of circle mouth, the flange butt joint auxiliary device is carried out travelling car 18 near belly pipe when work, selecting the quantity of support bar 20 to adjust omnidirectional mechanism 14 according to the clamping demand is evenly distributed in around the flange face it, regulate height by electric hydraulic operating desk 17 control Hydraulic Stations 19 control hoist cylinders 16, mobile active section 12 is so that C shape clamp are faced flange face again, fine setting C shape clamp, when the belly pipe of needs docking and reduced pipe gap meet standard, regulate Hydraulic Station 19 control hydraulic clamp clamp 2 by electric hydraulic operating desk 17 again and finish clamping work, then manually bolt is screwed, last pressure release, removal device.Whole process does not need to hit wedge with sledgehammer, can avoid knocking the inconvenience of bringing because of space problem with sledgehammer in the conventional method simultaneously.
In sum, flange butt joint auxiliary device of the present utility model can solve pipeline junction and the circle lip reflex occur and process the problem that wastes time and energy, and can also improve workman's operating efficiency and the safety coefficient of workman when work simultaneously.So, corresponding value is arranged aspect production and uses meaning thereby the utility model has effectively overcome practical problems more of the prior art.
Above-mentioned embodiment is illustrative principle of the present utility model and effect thereof only, but not is used for restriction the utility model.The utility model also many aspects can also improve such as the shape of clamp, the installation site of each mechanism etc. under the prerequisite of overall thought.Therefore, all can be under spirit of the present utility model and category for person skilled in the art scholar, can modify or change above-described embodiment.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under spirit that the utility model discloses and the technological thought, must be contained by claim of the present utility model.
