Technical field
This utility model relates to a kind of crane, is specifically related to one and is applicable in limited construction space The rotatable simple pole crane of operation.
Background technology
In each industrial working, colliery, usually there will be common crane during construction at present cannot normally enter Situation about using, as changed deep well submerged pump, interim stock ground weight loading-unloading vehicle etc., it may appear that during construction The situation that crane leaves to enter or crane car arm cannot stretch, and prior art lacks and can be applied to coal The pole of industrial working, ore deposit, mostly applies to pole or communication antenna that iron tower of power transmission line assembles Pole, this type of pole supporting structure is complicated, heavier-weight, and it is the most convenient to install, existing simply Pole rocking link is in the middle of pole, and crane arm coordinates with pole and easily produces stress when hoisting heavy Concentrate, make pole be easily generated flexural deformation, furthermore during work crane arm one end due to lifting heavy stress Relatively big, material mechanical performance understand moment of flexure suffered by the root of the crane arm other end relatively big, the most easily draw Play crane arm deformation, and the installation site of pulley is unfavorable for that electric winch drives heavy lift, so It is a kind of simple and reasonable that prior art is badly in need of design, and easy construction can be suitably used in industrial working Pole crane.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to carry For a kind of rotatable simple pole crane.This pole crane structure is simple, and using effect is good, energy Enough lifting carryings being efficiently completed plant equipment or weight in limited construction space, cost of manufacture Low, can be applicable.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of rotatable simple Pole crane, including base, it is characterised in that: rotated by pivoting support on described base and install There is installing plate, described installing plate is vertically fixed pole, described installing plate is provided with electric winch With the first fixed pulley, one end of lift heavy crossbeam is fixedly connected on described pole, described lift heavy crossbeam The other end is provided with the second fixed pulley, and institute walked around successively by the boom hoist cable stretched out from described electric winch Fix after stating the first fixed pulley, the second fixed pulley and being arranged on the movable pulley below described second fixed pulley Being connected on lift heavy crossbeam, described movable pulley connects has lifting frame, with described lift heavy on described pole The side that crossbeam is relative is installed with claw type auxiliary stand, and the top of described pole is provided with lightning-arrest Pin, the top of described pole is provided with becket bridle, and the end of described lift heavy crossbeam is by strengthening rope and rope Ring is connected.
Above-mentioned a kind of rotatable simple pole crane, it is characterised in that: described lift heavy crossbeam is straight Angle ladder beam.
Above-mentioned a kind of rotatable simple pole crane, it is characterised in that: described claw type auxiliary stand Including cross bar and the brace being symmetricly set on described cross bar both sides, it is connected between described cross bar and brace and has Reinforcement.
Above-mentioned a kind of rotatable simple pole crane, it is characterised in that: outside described pivoting support Circle is fixedly mounted on described base, and the inner ring of described pivoting support is fixing with described installing plate to be connected.
This utility model compared with prior art has the advantage that
1, this utility model is simple and reasonable, it is easy to processing and fabricating, novel in design, turns at needs Installing plate only need to be promoted time dynamic to rotate, and the bearing of trend of lift heavy crossbeam changes therewith, it is possible to achieve 360 ° of rotations, to reach hoisting operation requirement, this pole crane can be in limited construction space Being efficiently completed the lifting carrying of plant equipment or weight, using effect is good.
2, in this utility model, lift heavy crossbeam is preferably the right-angled trapezium beam of upper flat slanting, and lift heavy Crossbeam is relatively big with the area of pole junction, therefore relatively can reduce the flexural deformation of lift heavy crossbeam root, The structure making this pole crane is the most reliable, it addition, also can be according to job site practical situation needs Lifting frame is replaced by lifting hug, and easy to use, cost of manufacture is low, can be applicable.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Detailed description of the invention
A kind of rotatable simple pole crane as shown in Figure 1, including base 1, described base 1 On be rotatablely equipped with installing plate 3 by pivoting support 2, described installing plate 3 is vertically fixed pole 4, described installing plate 3 is provided with electric winch 5 and the first fixed pulley 6, one end of lift heavy crossbeam 7 Being fixedly connected on described pole 4, the other end of described lift heavy crossbeam 7 is provided with the second fixed pulley 8, The boom hoist cable 5-1 stretched out from described electric winch 5 walk around successively described first fixed pulley 6, Two fixed pulleys 8 are fixedly connected on lift heavy after being arranged on the movable pulley 9 below described second fixed pulley 8 On crossbeam 7, described movable pulley 9 is connected by rope and has lifting frame 10, with institute on described pole 4 State the relative side of lift heavy crossbeam 7 and be installed with claw type auxiliary stand 11, the top of described pole 4 Being provided with discharging rod 12, the top of described pole 4 is provided with becket bridle 13, described lift heavy crossbeam 7 End is connected with becket bridle 13 by strengthening rope 14.
As it is shown in figure 1, in the present embodiment, described lift heavy crossbeam 7 is right-angled trapezium beam, described right angle Ladder beam is upper flat slanting, and lift heavy crossbeam 7 root is relatively big with the connection area of lift heavy crossbeam 7, has It is beneficial to prevent lift heavy crossbeam 7 from deforming.
