The setting of above-mentioned multiple contact disk, is convenient to form electric potential difference, is more conducive to the stability of powering.
It should be noted that, above-mentioned setting height those skilled in the art can rule of thumb set.
The top of above-mentioned contact cover 11 can be installed on the movable pulley 2 that suspension strap in construction machinery and equipment carries in the lifting pulley of downward putting device, can carry downward putting device lifting to realize contact cover with band.
Preferably in embodiment, as shown in Figure 3, Fig. 3 is the A place partial enlarged drawing with the construction machinery and equipment of band year downward putting device provided by the invention shown in Fig. 2, contact plate 111 is made up of electromagnetic material, power supply is the feed circuit of the controller of construction machinery and equipment, contact modules 31 also comprises: magnetic chuck 314, and magnetic chuck 314 is provided with the second joint 3141 be connected with the feed circuit of the controller of construction machinery and equipment.The feed circuit of the controller of construction machinery and equipment are energized to magnetic chuck 314 by the second joint 3141, magnetic chuck 314 can produce magnetic force after being energized, when contact modules 31 contacts with contact plate 111, magnetic chuck 314 can hold contact plate 111, and then hold contact cover 11, and visible, the setting of magnetic chuck 314, the stability that control module 4 provides electric energy can be risen to, the stability contacting cover 11 when weight 5 breaks off relations can also be improved simultaneously.
Continue with reference to figure 3, contact modules 31 also comprises: cover the protective case 313 be buckled in outside magnetic chuck 314, insulate and arrange between protective case 313 and magnetic chuck 314.
Above-mentioned protective case 313 is the cube structure of one end open; the open end of protective case 313 is towards contact cover 11; the number of contact disk 312 is four, in parallel between four contact disks 312, and four contact disks 312 lay respectively on protective case 11 side adjacent with its open end.So that better for control module provides electric energy.
The concrete structure of above-mentioned contact cover 11 can have multiple, as shown in Figure 3, contact cover 11 also comprises: multi-disc division board 112, and contact cover 11 be surrounded by multi-disc division board 112 inner hollow, one end open structure, the lateral surface on the top of contact cover 11 forms exit skirt shape, the lateral surface of bottom forms the polyhedron-shaped of both ends open, and the large end of the exit skirt shape on the top of contact cover 11 connects with a polyhedron-shaped open end of the bottom contacting cover 11.
In a kind of detailed description of the invention, the lateral surface of the bottom of contact cover 11 is formed as both ends open rectangular shape, and contact plate 111 is four pieces, four pieces of contact plates 111 are by cuboid four lateral surfaces of insulating collar 113 both ends open of the bottom of imbedding and contact cover 11 one to one;
As shown in Figure 4, Fig. 4 carries the construction machinery and equipment B of downward putting device to structural representation for provided by the invention shown in Fig. 2 has band, contact modules 31 is four, each contact modules 31 hangs on construction machinery and equipment support respectively by two suspension cables 6, and two suspension cables 6 with the corresponding contact plate 111 contacted of the contact modules 11 of its suspension is projected as herringbone.The design of herringbone can make contact modules 31 better locate, and the contact disk 312 of contact modules 31 is contacted with contact plate 111 more accurately.
Optionally, above-mentioned contact disk 312 is spring contact plate.Certain contact disk is not limited to spring contact plate, just repeats no longer one by one here.
Present invention also offers a kind of construction machinery and equipment, comprise: band carries downward putting device, also comprise: the described band of above-mentioned any one carries the power equipment supply of downward putting device, the power supply that the second contact device in power equipment supply connects is the feed circuit of the controller of described construction machinery and equipment.Because above-mentioned band carries the power equipment supply of downward putting device, the generation that supply cable is involved in the phenomenon of suspension hook can be reduced, improve construction machinery and equipment service life and safety in utilization, so, construction machinery and equipment provided by the invention, there is higher service life and good safety in utilization, and construction machinery and equipment also can use under the occasion of high energy consumption.
In a kind of detailed description of the invention, above-mentioned band the first contact device carried in the power equipment supply of downward putting device is installed in construction machinery and equipment and hangs described band and carry movable pulley in the lifting pulley of downward putting device.
Above-mentioned construction machinery and equipment can be hoisting crane, and dynamic compaction machinery etc. have the structure that band carries downward putting device.Take construction machinery and equipment as hoisting crane be example, construction machinery and equipment provided by the invention, the feed circuit of the controller of construction machinery and equipment are connected to form power equipment supply feed circuit, for the two provides electric energy by supply cable and the first joint 311 and the second joint 3141.Time initial, contact cover 11 is positioned at the below of contact modules 31, weight triggers by the suspension hook that band carries downward putting device, hoisting crane upwards promotes, contact cover 11 is with lifting pulley upward movement, the top cone structure of contact cover 11 pushes contact modules 31 open, contact modules 31 slides along the top conical surface of contact cover 11, along with hoisting crane further upwards promotes, contact modules 31 slides the conical surface of contact cover 11, under the effect of gravity and suspension cable pulling force, contact modules 31 presses close to contact polyhedral side of cover 11 bottom, when contact modules 31 is just to contact plate 111, hoisting crane stops upwards promoting, spring contact plate is compressed under the gravity of contact modules 31 and the effect of suspension cable pulling force, until contact plate 111 and magnetic chuck 314 are adjacent to, after touch panel 111 waiting is adjacent to magnetic chuck 314, electric energy is passed to control module 4 by the first joint 311, contact disk 312 and contact plate 111 by the feed circuit of the controller of construction machinery and equipment, after control module 4 receives electric energy, control hook is broken off relations and weight 5 is put down, due in decentralization process, band is carried downward putting device and covers by contact cover 11, therefore the hook that band carries on downward putting device can not catch on supply cable line, when again needing to hook lift heavy thing 5, the feed circuit of the controller of construction machinery and equipment no longer give spring contact plate and magnetic chuck 34 electric energy, and now, contact modules 31 will be separated with contacting cover 11, and contact cover 11 just can again along with lifting pulley up-and-down movement.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
