Detailed description of the invention
Below detailed description of the invention of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent in appended claim, the utility model creation that all utilize the utility model to conceive is all at the row of protection.
The hound shown as the arm tower crane of the utility model embodiment with reference to figure 1, Fig. 1 is fixedly mounted on ground structural representation with revolution undersetting by anchor structure; As shown in Figure 1, the technical scheme that the present embodiment adopts is:
This arm tower crane comprises crane arm, the revolution upper bracket 6 linked together by gyration gear ring and revolution undersetting 7, revolution upper bracket 6 is provided with the swing type mechanism engine installation 9 driving revolution upper bracket 6 to rotate, and swing type mechanism engine installation 9 can be motor.Wherein crane arm 2 is arranged on revolution upper bracket 6 by rotating shaft, and the steel cable that the tip of crane arm 2 faces upward the torque arm mechanism 12 of bowing with for controlling it by crane arm pull bar 3 is connected; Suspension hook 1 on crane arm 2 is elevated the lifting mechanism 11 carrying out weight lifting with one is connected for controlling suspension hook 1.
Revolution upper bracket 6 is also provided with a root post 5 by shipping and reselling on another market, and column 5 adopts vertical mode to be fixedly mounted on revolution upper bracket 6; Column 5 is fixed on ground with at least one, is connected for the hound 8 of support post 5 with adjusting post 5 squareness; Hound 8 can be installed on the ground by bolt, by the squareness of adjusting bolt adjusting post 5 during installation, turns round during to ensure that tower machine turns round with the axial line of column 5.
Above-mentioned swing type mechanism engine installation 9, torque arm mechanism 12 are all connected with electric control system 14 with lifting mechanism 11, are realizing the lifting of weight and are driving weight rotation all automatically can be completed by the control of electric control system 14.The implementation procedure rotated in the lifting and drive weight that realize weight is: the rotation being controlled swing type mechanism engine installation 9 by electric control system 14, swing type mechanism engine installation 9 drives revolution upper bracket 6 to rotate by driving gyration gear ring, and then drives the crane arm 2 on revolution upper bracket 6 and column 5 to rotate.
Pull-up weighing arm 2 steel rope that the reel of torque arm mechanism 12 is wound around is fixed on crane arm 2 by the pulley on crane arm pull bar 3 after walking around the fixed pulley group 4 of installing at column 5 top, controlled the rotation of torque arm mechanism reel by electric control system 14, and then the amplitude of bowing of facing upward completing crane arm converts.
In the implementation procedure of the lifting realizing weight be: the reel of lifting mechanism 11 is wound around steel wire ropes for hoisting, hoist rope moves in suspension hook 1 by crane arm 2 arm point after walking around the rope pulley excessively in the fixed pulley group in the middle part of column 5, controlled the rotation of the reel of lifting mechanism 11 by electric control system 14, and then the lifting of weight is carried out in the lifting completing 1 group, suspension hook.
When this arm tower crane be arranged on roof carry out the dismounting of other goliaths time, as long as it is smooth for meeting revolution undersetting 7 installation position place, other positions can according to the concrete structure on roof by expansion bolt or girder steel and building fixing.
Fig. 5 show two hounds 8 link together with column 5 after birds-eye view; As shown in Figure 5 when hound 8 is one, when this hoisting crane turns round, the pulling force of a hound 8 is limited, is difficult to meet operating needs, so in an embodiment of the present utility model, the hound 8 that column 5 can be fixed on the ground by two connects.If when the horizontal projection angle of two hounds 8 is less, the pulling force of itself an and employing hound 8 is similar, and effect is little.When the horizontal projection angle of two hounds 8 is very large, although it provides larger pulling force can to column 5, but the rotational steps of crane arm 2 can be had a strong impact on, so the installation horizontal projection angle of two hounds 8 can be arranged on about 90 °, be preferably 90 °, the maximum rotational steps of such crane arm 2 can reach 220 °.
With reference to figure 2, in an embodiment of the present utility model, hound 8 and revolution undersetting 6 can be fixedly mounted on the ground by anchor structure 13.Because the size of anchor structure 13 can be selected according to in-site installation area, the pressure of roof carrying during arm tower crane hoisting heavy can be disperseed like this, avoid local area stressed excessive, damage is caused to building.
With reference to figure 2, when the area on roof is enough large, can fixedly mount an equilibrium arm 15 on revolution upper bracket 6, the increase of equilibrium arm 15 can improve the stability of arm tower crane further, can increase the bearing load of arm tower crane so further.In this case, when carrying out arm tower crane installation, before installation column 5, can first strut bar 10 be connected on column 5, after column 5 and revolution upper bracket 6 connect, use bearing pin to be arranged on equilibrium arm 15 or ground with support post 5 pin-and-hole of strut bar 10 lower end.
When roof area is enough wide, torque arm mechanism 12, electric control system 14 and lifting mechanism 11 all can fixedly mount on the ground.
With reference to figure 2, but when the area on roof is less, be difficult to install downward moving arm tower crane when realizing the necessary parts hoisted, generally can adopt and fixedly mount an equilibrium arm 15 on revolution upper bracket 6, equilibrium arm 15 now is just being not stability for improving arm tower crane further, but for carrying torque arm mechanism 12, electric control system 14 and lifting mechanism 11.
With reference to figure 3 and Fig. 4, when roof is installed arm tower crane, pressure for the ease of roof carrying scatter as much as possible, can also at least fixedly mount three supporting legs 16 at the edge of revolution undersetting 7, be equivalent to so at least be provided with three stress points in the below of revolution undersetting 7; Supporting leg 16 is fixedly mounted on the ground by anchor structure 13.The stressed of such house can be disperseed by multiple supporting legs 16 of installation and anchor structure 13, avoids roof local pressure, occurs cracking or other damages.When carrying out roof and installing, consider from the angle of assembly and disassembly, be typically chosen in upper four supporting legs 16 of edge fixed installation of revolution undersetting 7.
With reference to figure 6, it illustrates the technical scheme that arm tower crane one and the embodiment provided exist following distinguishing characteristics above:
The revolution upper bracket 6 of this technical scheme is installed with an equilibrium arm 15, the hound 8 for support post 5 and adjusting post 5 squareness is arranged on equilibrium arm 15 instead of installs on the ground.
The technical scheme of this mode is except revolution upper bracket 15 is installed with an equilibrium arm 15, be arranged on outside the mounting means of two parts on equilibrium arm 15 and each technical scheme above-mentioned have any different for the hound 8 of support post 5 and adjusting post 5 squareness, the structure of other parts all can adopt the identical mode of technique scheme to install, the various distortion that prior art scheme is mentioned, are equally also applicable to the distortion of the technical scheme in Fig. 6.
