The utility model discloses simple structure, main davit and the vice davit regulation length of can stretching out and drawing back, low in cost uses and adjusts quick conveniently, and the storage space that occupies moreover is little.
Description
Technical field
The utility model belongs to casing of preinstalled type substation lifting device field, particularly relates to a kind of lifting arm of lifting casing of preinstalled type substation.
Background technology
Casing of preinstalled type substation of the prior art, in hoisting process, needs to coordinate lifting rope to lift by crane by the arm of corresponding size.The casing of preinstalled type substation of different size needs the special arm making corresponding size, the casing of preinstalled type substation of so each replacing different size just needs making arm, not only high degree causes the waste of steel, and larger-size arm also needs to consume larger storage space.
Utility model content
The purpose of this utility model is to provide a kind of lifting arm, and the utility model structure is simple, and main arm and secondary arm can telescopic adjustment length, cheap, take up space little.
The technical solution adopted in the utility model is as follows:
A kind of lifting arm, described a kind of lifting arm comprises the main arm of tubular, the each free-running fit in main arm two ends is provided with secondary arm, main arm and secondary arm are all provided with jack, and main arm and secondary arm realize removably connecting with coordinating of jack by set pin, and secondary arm end is installed with hanging block, hanging block top is provided with the first lifting hole(eyelet), bottom is provided with the second lifting hole(eyelet), and the first lifting hole(eyelet) is connected with hawser, and the second lifting hole(eyelet) is connected with casing of preinstalled type substation by lifting rope.
Preferably, in described main arm, center radial direction is installed with two parallel connecting rods, and every root connecting rod is connected with one end of elastic component, and the elastic component other end is connected with corresponding secondary arm end.
Preferably, described elastic component is volute spiral spring.
During work, according to the size of required lifting casing of preinstalled type substation, by two secondary arms along main arm axial sliding movement to appropriate length, now volute spiral spring is in extended state.Then set pin is inserted jack on main arm and secondary arm with the relative position of fixing main arm and secondary arm.Again lifting rope is connected with casing of preinstalled type substation, by the cooperation of hawser, arm and lifting rope, by casing of preinstalled type substation lifting to target location.
After rigging out, be separated by lifting rope with casing of preinstalled type substation, then be separated with jack by set pin, the utility model, under the reset pulling force of volute spiral spring, along main arm axis direction retraction, is placed by two secondary arms.
Compared with prior art, tool has the following advantages the utility model:
This novel a kind of lifting arm structure is simple, and main arm and secondary arm can telescopic adjustment length, and cheap, adjustment in use is quick and convenient, and the storage space occupied is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of lifting arm in detailed description of the invention;
Fig. 2 is the structural representation of a kind of lifting arm in detailed description of the invention;
Fig. 3 is main arm inner structure schematic diagram in Fig. 2.
Be labeled as in figure: main arm 1, secondary arm 2, hanging block 3, the first lifting hole(eyelet) 4, second lifting hole(eyelet) 5, first jack 6, hawser 7, lifting rope 8, the second jack 9, volute spiral spring 10, connecting rod 11.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, a kind of lifting arm, described suspender comprises the main arm 1 of tubular, the each free-running fit in main arm 1 two ends is provided with secondary arm 2, main arm 1 is provided with the first jack 6, secondary arm 2 is provided with the second jack 9, main arm 1 and secondary arm 2 realize removably connecting with the first jack 6 and coordinating of the second jack 9 by set pin, secondary arm 2 end is installed with hanging block 3, hanging block 3 top is provided with the first lifting hole(eyelet) 4, bottom is provided with the second lifting hole(eyelet) 5, first lifting hole(eyelet) 4 and is connected with hawser 7, and the second lifting hole(eyelet) 5 is connected with casing of preinstalled type substation by lifting rope 8.In main arm 1, center radial direction is installed with two parallel connecting rods 11, and every root connecting rod 11 is connected with one end of volute spiral spring 10, and volute spiral spring 10 other end is connected with corresponding secondary arm 2 end.
During work, according to the size of required lifting casing of preinstalled type substation, by two secondary arms 2 along main arm 1 axial sliding movement to appropriate length, now volute spiral spring 10 is in extended state.Then set pin is inserted the second jack 9 on the first jack 6 of main arm 1 and secondary arm 2 with the relative position of fixing main arm 1 and secondary arm 2.Again lifting rope 8 is connected with casing of preinstalled type substation, by the cooperation of hawser 7, main arm 1, secondary arm 2 and lifting rope 8, by casing of preinstalled type substation lifting to target location.
After rigging out, be separated by lifting rope 8 with casing of preinstalled type substation, then be separated with the second jack 9 with the first jack 6 by set pin, the utility model, under the reset pulling force of volute spiral spring 10, along main arm 1 axis direction retraction, is placed by two secondary arms 2.
