Abstract
Disclosed is a tube panel hoisting turning tool. The technical scheme of the tube panel hoisting turning tool includes that crab jaws capable of being opened and closed comprises a body and clamping blocks, and the tube panel hoisting turning tool matches with an ejector rod only capable of rotating positively and reversely for 90 degrees. When the ejector rod positively rotates for 90 degrees, press feet of the ejector rod fall into clamping block grooves, and the clamping blocks can be opened to be installed into a tube panel. After the clamping blocks are closed and the ejector rod rotates reversely for 90 degrees, the press feet of the ejector rod are pressed on the clamping blocks, the clamping blocks can not be opened, and hoisting can be performed. In addition, synclastic teeth respectively arranged on the press feet and the clamping blocks are embedded into each other, the ejector rod can be prevented from rotating, thereby being safe and reliable. The whole process has only a release work position and a closed work position, is operated completely manually, and the tube panel hoisting turning tool is simple, convenient, flexible, time-saving and safe, and overcomes the shortcomings of cutting off of an existing steel wire rope by flat steel at the edge of the tube panel.
Description
Affiliated technical field
The utility model is applied to the station boiler originating firm, lifts by crane, stands up tube panel and use.
Background technology
At present, it is big in batches that China's station boiler originating firm is produced tube panel, and tube panel is welded by many pipes and band steel, needs lifting in the production process, stands up, and number of times is frequent.Boilermaker adopts steel rope directly to lift by crane, stand up, and operation easily causes steel rope to be cut off by the band steel on the tube panel limit like this, and the steel rope rapid wear stands up also inconvenient.
Summary of the invention
Directly lift by crane tube panel and easily cause steel rope to be cut off by the band steel on the tube panel limit in order to overcome existing steel rope, the steel rope rapid wear stands up also inconvenient deficiency, and the utility model provides a kind of convenient mounting and clamping, stands up easy lifting tool.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of tube panel hoisting and overturning instrument is carrier with the body, there is the flat tongue of protrusion at its place of taking over, lower end, on the flat tongue circular hole is arranged, the fixture block that has same circular hole, middle fluting is embedded flat tongue, load onto the bearing pin that has step, have horizontal pin-and-hole at the bearing pin other end, insert spring cotter, fixture block can rotate around bearing pin, opening is adjustable, and fixture block and body form open-close type crab claw type jaw, open and then put into the tube panel pipe, close and then embrace pipe, then can lift by crane.Fixture block top has transverse teeth and push rod lower end profile of tooth embeds mutually, in case the push rod rotation.Weld mutually with ∏ shape handle the fixture block lower right; The body upper right side has oblique tapped bore and push rod matches, the push rod lower end is the flat, rectangular presser feet, and have tooth and a fixture block embedding mutually, the top of its thread segment is that the center square hole of square column and handwheel matches to transmit rotation, epimere nut, the anti-handwheel of packing ring are deviate from, the cylindrical of handwheel has 90 ° of arc gaps, straight pin from then on breach squeeze in the body with the control handwheel drive push rod can only cw or conter clockwise change 90 °, formation is to the control mechanism of jaw folding, when hand-motion push rod cw changes 90 °, jaw can free folding; When 90 ° of push rod conter clockwise commentaries on classics, then jaw can not be opened.Have the latch that cylindrical hole and the shackle of gauge member rigging carry directly over the body and match, rigging shackle top penetrates steel rope and links to each other with shop traveller.
Adopt open and close type but clamp, convenient mounting and clamping, clamped position is not limited.
Push rod and fixture block seal face all have tooth in the same way, and lifting back fixture block is difficult for rotating; Push rod top adopts square toes to be connected with handwheel, and handwheel is by straight pin restriction push rod degreeof turn (90 °), and is safe and reliable.
This instrument can be put down and be hung, and also can stand and hang, stands up.
The beneficial effects of the utility model are: overcome existing steel rope and directly lift by crane tube panel and easily cause steel rope to be cut off by the band steel on the tube panel limit, the steel rope rapid wear stands up also inconvenient deficiency, and is easy to use, safe and efficient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Among the figure: 1. fixture block, 2. handle, 3. bearing pin, 4. spring cotter, 5. push rod, 6. packing ring, 7. nut, 8. handwheel, 9. straight pin, 10. body, 11. rigging shackles, 12. steel ropes.
The specific embodiment
In the accompanying drawings, with body (10) is carrier, there is the flat tongue of protrusion at its place of taking over, lower end, on the flat tongue circular hole is arranged, the fixture block (1) that has same circular hole, middle fluting is embedded flat tongue, load onto the bearing pin (3) that has step, have horizontal pin-and-hole at bearing pin (3) other end, insert spring cotter (4), body (10) forms crab claw type jaw with fixture block (1), can open and can close.Open and then put into the tube panel pipe, close and then embrace pipe, then can lift by crane.Fixture block (1) top has transverse teeth and push rod (5) lower end profile of tooth embeds mutually, in case the push rod rotation.Weld mutually with ∏ shape handle (2) fixture block (1) lower right; Body (10) upper right side has oblique tapped bore and push rod (5) matches, push rod (5) lower end is the flat, rectangular presser feet, and have tooth and fixture block (a 1) embedding mutually, the top of its thread segment is that the center square hole of square column and handwheel (8) matches to transmit rotation, epimere nut (7), the anti-handwheel (8) of packing ring (6) are deviate from, the cylindrical of handwheel (8) has 90 ° of arc gaps, straight pin (9) from breach squeeze into the body (10) with control handwheel (8) can only cw or conter clockwise change 90 °; Have the latch that cylindrical hole and gauge member rigging shackle (11) carry directly over the body (10) and match, rigging shackle (11) top penetrates steel rope (12) and links to each other with shop traveller.
During use, 90 ° of push rod (5) head clickwises are arrived diagram dotted line position place, the flat head of its lower end then falls into the inside groove of fixture block (1), do not influence opening of fixture block (1), move fixture block (1) to the dotted line place again, insert the tube panel pipe, put down fixture block (1), to the diagram solid line position, at this moment, the flat head in push rod (5) the lower end then top both sides shoulder of going up fixture block (1) is gone up (centre is a groove) with 90 ° of push rod (5) head left-hand revolutions.Then can lift by crane, stand up.Accompanying drawing hangs or stands up for upright, and each then can be put down and hang with two these instruments in the tube panel both sides.In the lifting process, because the action of gravity of tube panel, force fixture block (1) outside bearing pin (3) conter clockwise, to change (seeing accompanying drawing), prop up the lower end of push rod (5), at this moment, fixture block (1) can embed mutually under weight with the tooth in the same way of push rod (5), then prevents the rotation of push rod (5) in the lifting process, guarantees safe and reliable.
In the whole process, fixture block (1) has only the folding two states, and handwheel (8) also has only cw or conter clockwise to change 90 ° of two kinds of actions, all uses manual manipulation, and is easy, flexible, save time.
