Abstract
The utility model relates to an internal expanding type lifts by crane instrument, it includes: the solar apparatus further comprises a supporting mechanism, the supporting mechanism is including supporting the disk body, installing support on the disk body and be in many supporting legs in the coplanar and set up in support the traction lever of disk body top, the traction lever perpendicular to is many the plane that the supporting leg was located, fixture, fixture include the middle part with supporting leg looks pivoted joint and quantity rather than the first branch of unanimity and one end and first branch tip looks pivoted joint and another tip and traction lever looks pivoted joint's second branch, another tip of first branch be equipped with with supporting leg matched with clamping jaw, utilize the clamping jaw to catch hold of the product bottom with a hook and coordinate the supporting leg like this, rely on and hang locking from weight of thing, prevent the finished product because the iron wire fracture from directly falling to downstairs, avoids causing serious equipment and life incident upstairs.
Description
Technical field
This utility model relates to a kind of lifting tool, is specifically related to a kind of internal expansion type lifting tool.
Background technology
The production of China's prestressing steel is started in the initial stage sixties, only has 4.5 ten thousand tons because being had influence on 20th century the mid-80 production capacity by planned economy, and principal item is common lax level compressor wire, steel strand wires and modulation heat-treated steel bar, belongs to low grade products.Along with China's reform and opening-up and the deepening continuously of economic construction, through country " six or five ", " the Seventh Five-Year Plan ", " eight or five ", the development of the enforcement period of the ninth five-year plan, China's prestressing steel production technology there occurs the change of matter with equipment, pull developing rapidly of China's high-speed wire mill, also promoting the design of prestressed reinforced concrete construction engineering field, construction and the technological progress of materials and update, prestressed steel bar use in engineering obtains bigger development space simultaneously.
I takes charge of the apparatus for production line of prestressed steel bar upstairs, the finished product so produced all can be placed on upstairs by temporary heap, every three guarantees meeting 6mm iron wire carries out three roads and ties up, then warehouse for finished product downstairs is winched to three-jaw chain, owing to the quality of three road iron wires does not detects, it is very likely to occur fracture accident during lifting, makes three guarantees finished product pound from upstairs, abnormally dangerous.
Summary of the invention
This utility model purpose is to provide a kind of internal expansion type lifting tool to overcome the deficiencies in the prior art.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of internal expansion type lifting tool, and it includes:
Supporting mechanism, described supporting mechanism includes supporting disk body, the many supporting legs being arranged on described support disk body and being in same plane and being arranged at the draw bar above described support disk body, and described draw bar is perpendicular to the plane residing for many described supporting legs；
Clamping device, described clamping device includes the first pole that middle part connects and quantity is consistent with it and the second pole that one end is connected with described first strut ends phase pivot and the other end is connected with draw bar phase pivot with described supporting leg phase pivot, and described first pole the other end is provided with the jaw matched with described supporting leg；
Hoisting ring, described hoisting ring is arranged on the top of described draw bar.
Optimally, described supporting leg offers the slotted eye passed for described first pole.
Optimally, described support disk body being provided with opening/closing device, pivotally connected on described draw bar have the multiple claws matched with described opening/closing device.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that this utility model internal expansion type lifting tool, matched by the supporting mechanism and clamping device using ad hoc structure, jaw is so utilized to be hooked to bottom product and coordinate supporting leg, rely on and hang locking from weight of thing, prevent finished product from rupturing from the most directly dropping to downstairs due to iron wire, it is to avoid to cause serious equipment and life security incident.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model internal expansion type lifting tool；
Wherein, 1, supporting mechanism；11, disk body is supported；12, supporting leg；13, draw bar；14, opening/closing device；15, claw；2, clamping device；21, the first pole；211, jaw；22, the second pole.
Detailed description of the invention
This utility model is further described by the embodiment shown in below in conjunction with the accompanying drawings.
Internal expansion type lifting tool as shown in Figure 1, mainly includes that supporting mechanism 1, clamping device 2 and hoisting ring 3, supporting mechanism 1 and clamping device 2 cooperate, and hoisting ring 3 is arranged on the top of supporting mechanism 1.
Wherein, supporting mechanism 1 includes supporting disk body 11, supporting leg 12 and draw bar 13.Supporting leg 12 has multiple, and they are arranged on support disk body 11, and are in same plane；It can be made to be installed in rotation on pivotally connected with support disk body 11 for its end on support disk body 11 as required, convenient for collecting；In the present embodiment, supporting leg 12 is three, and the angle between adjacent two supporting legs 12 is 120 °.Draw bar 13 is arranged at the top supporting disk body 11, and it is perpendicular to the plane of three supporting leg 12 places (or residing).Clamping device 2 includes the first pole 21 and the second pole 22, and its quantity is consistent with the quantity of supporting leg 12 respectively, thus is matched therewith.The lower end of the first pole 21 is provided with the jaw 211 matched with supporting leg 12, and its middle part is connected with supporting leg 12 phase pivot；One end of second pole 22 is connected with the upper end phase pivot of the first pole 21, and the other end is connected with draw bar 13 phase pivot.So utilize jaw 211 to be hooked to bottom product and coordinate supporting leg 12, relying on and hang locking from weight of thing, preventing finished product from rupturing from the most directly dropping to downstairs due to iron wire, it is to avoid to cause serious equipment and life security incident.Hoisting ring 3 is arranged on the top of draw bar 13, for the lifting of internal expansion type lifting tool.
In the present embodiment, supporting leg 12 offers the slotted eye 121 passed for the first pole 21.The pivot of the first pole 21 and supporting leg 12 is i.e. arranged on them and intersects part.Supporting and be provided with opening/closing device 14 on disk body 11, pivotally connected on draw bar 13 have the multiple claws 15 matched with opening/closing device 14, and such draw bar 13 is connected with the opening/closing device 14 supported on disk body 11 by claw 15；When internal expansion type lifting tool does not uses, it is used for ensureing that it is in contraction state；When needs use, need to open claw 15 by opening/closing device 14.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
