Abstract
The utility model relates to a support frame of support drum inner wall. The utility model discloses constitute by support, hand wheel, lead screw, connecting seat, connecting rod, arc fagging, activity fagging, lead screw horizontal connection is on the support, and the tip is equipped with the hand wheel, and the lead screw is established two screw threads in opposite directions respectively toward both ends by the centre, connects two connecting seats respectively, and a arc fagging is connected on the radial even articulated a plurality of connecting rods of connecting seat, the top of two connecting rods that two connecting seats correspond, and a plurality of arc faggings form the ring form through activity fagging swing joint. The utility model discloses utilize the bracing piece of radial equipartition to realize supporting-reseing, can realize the wholeness of circumference under the support state, when the sealing washer cover was established on the support frame, guaranteed sealed reliability. The utility model discloses convenient operation is reliable, greatly reduced personnel's intensity of labour, realized quick installation in narrow and small space.
Description
Technical field
The utility model relates to a kind of supporting mechanism, relates in particular to the supporting frame of support cylinder inwall.
Background technique
For the support of cylinder inner wall, be to play two or several arc dunnages with they sup-port to realize that defective is can not realize circumferentially contacting fully with barrel mostly, and load and unload cumbersomely that personnel labor intensity is big.At present, the under ground piping in the municipal engineering adopts prefabricated pipe, and the seam of pipeline junction requires ne-leakage.In actual engineering, every pipeline has the hundreds of bar at least, at most several thousand in addition up to ten thousand interfaces need to handle, careless slightly in the construction, just might cause the seepage generation.Traditional detecting method of past is that pour water pressurization or arc dunnage of segmentation supports seal ring and detect whether seepage of seam, segmentation is poured water pressurization owing to need a large amount of water, and be not easy accurately to locate leakage point and abandoned, the form that arc dunnage support seal ring detects seam one by one is widely adopted, when operator install seal arrangement in pipeline, need connect some part stack mountings, workload is big, manual reliability is also poor, and it is bad to cause seal arrangement itself to combine with tube wall easily.
Summary of the invention
The utility model provides a kind of at above defective and can move in the cylinder, realizes the supporting frame that supports-reset by operating lever.
The technical solution of the utility model is: it is made up of support, handwheel, screw mandrel, connecting base, connecting rod, arc fagging, Movable fagging, the screw mandrel level is connected on the support, the end is provided with handwheel, screw mandrel is by middle two in opposite directions the screw threads of establishing respectively toward two ends, connect two connecting bases respectively, the radially even hinged some connecting rods of connecting base, the top of two connecting rods of two connecting base correspondences connects an arc fagging, some arc faggings flexibly connect by Movable fagging, form circular.
Described support is provided with castor.
Described connecting rod is 12 pairs.
Described connecting rod middle part is provided with adjusting nut.
Described arc fagging is provided with the hole that is connected with Movable fagging, and the bottom is provided with the hole with rod hinge connection, and the both sides of Movable fagging are respectively equipped with the groove that flexibly connects with the arc fagging.
The utility model is subjected to the inspiration of the folding structure of umbrella, utilizes radial uniform strut to realize support-reset; Top at each connecting rod flexibly connects the arc fagging, connect by Movable fagging between the arc fagging, Movable fagging and arc fagging are hinged, Movable fagging is provided with chute in the hinged place, can under holding state, realize circumferential integrity, when seal ring is set on the supporting frame, guaranteed the reliability of sealing.The utility model convenient and reliable operation greatly reduces personnel's labor intensity, has realized quick mounting in small space.

Embodiment
Flexibly connect leading screw 4 on the support 1, handwheel 5 is established at leading screw 4 two ends, and leading screw 4 can be set a device by middle two in opposite directions the screw threads of establishing respectively toward two ends in the middle of the leading screw 4, and the positioning device sky is enclosed within on the leading screw 4; Two ends are provided with connecting base 3 respectively on leading screw 4, two connecting bases 3 move respectively in opposite directions when leading screw 4 rotations, connecting base 3 connects arc fagging 8 by connecting rod 2, the arc fagging 8 that each connecting rod 2 connects connects by Movable fagging 9, Movable fagging 9 is hinged with arc fagging 8, and Movable fagging 9 is provided with chute in the hinged place, can realize circumferential integrity under holding state, when seal ring 11 and pneumatic tyre 12 are set on the supporting frame, guaranteed the reliability of sealing; When reset mode, the end face of the end face of Movable fagging 9 and arc fagging 8 is not on a profile line.
Castor is established in lower end at support 1, can conveniently move in pipeline 14, and the seam 13 of corresponding pipeline 14 supports this supporting frame, realizes the support location to seal ring 11 and pneumatic tyre 12, and effectively seal ring 11 and pneumatic tyre 12 circumferentially is pressed on seam 13 places.
Supporting frame of the present utility model can be provided with drive unit, can realize automatic operation.
