Description
Technical Field
The utility model particularly relates to an on-spot quick-operation joint device of fire-resistant bus duct
Background
Modern high-rise buildings and large workshops need huge electric energy, and safe and reliable conduction equipment needs to be selected in the face of the huge load needing hundreds of thousands of amperes of strong current, so that a bus system is a good choice. The bus duct system is a power distribution device for efficiently transmitting current, and particularly meets the requirements of economic and reasonable wiring of higher and higher buildings and large-scale factories. The tapping unit of current bus duct is mostly the plug-in type, can't satisfy the operation requirement when drawing electric current great, has certain potential safety hazard, and short circuit easily takes place in the long-time use, and the emergence accident threatens enterprise and staff's personal safety. The connection between the current bus duct unit adopts the direct overlap joint of bus joint ware more, but the bus duct is in the overlap joint, and complex operation can appear the overlap joint unstably in the overlap joint, and the deviation can appear in the ware that connects when the fastening, leads to the bus duct to transmit information effect poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving prior art's not enough, provide a scene quick-operation joint device of fire-resistant bus duct, including two block up-and-down symmetry's clamp plate and a bolt that passes two clamp plates perpendicularly, the inboard of clamp plate be equipped with the stopper, the bolt on the cover be equipped with a plurality of Z type and separate the packing ring, the upper end of bolt links to each other with the nut cooperation, the nut install on last clamp plate.
Preferably, the bolts are stud torque bolts.
Preferably, the clamping plate is provided with two bilaterally symmetrical bending pieces, and the distance L between the two bending pieces is larger than the outer diameter of the bolt.
Preferably, an indicating washer is arranged between the bolt and the bending piece on the lower clamping plate, and the indicating washer is an incomplete circular washer.
Preferably, the outer diameter of the indicating washer is larger than the distance L between the two bent sheets.
In order to ensure uniform pressure, moderate tightness and safe and reliable electrical connection on the contact surface of the whole bus duct, the separating gasket is preferably a high-pressure equalizing gasket.
Preferably, the separation washer is sleeved on the bolt in an up-and-down symmetrical mode.
Has the advantages that: the utility model discloses an on-spot quick-operation joint device of fire-resistant bus duct, traditional structural design has been abandoned to this piecing devices, has guaranteed that the phenomenon of bus duct disconnected in whole connection process can not take place, has simplified the installation, has improved the installation rate between the bus duct.
Drawings
FIG. 1 is a schematic structural diagram of a fire-resistant busway field quick connector device;
FIG. 2 is a schematic view of an assembly structure of a fire-resistant bus duct on-site quick connector device;
in the figure: 1. clamping plate 11, upper clamping plate 12, lower clamping plate 13, limiting block 14, bending piece 15, indicating washer 2, bolt 3, separating washer 4, nut 5, fire-resistant bus duct 51, bus duct cover plate 52 and tapping unit
Detailed description of the preferred embodiments
In order to deepen the understanding of the present invention, the present invention is described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in figure 1, the on-site quick joint device for the fire-resistant bus duct comprises two clamping plates 1 which are symmetrical up and down and a bolt 2 which vertically penetrates through the two clamping plates, two bilaterally symmetrical limiting blocks 13 are arranged on the inner side of the clamping plate 1, two bilaterally symmetrical bending pieces 14 are arranged on the clamping plate 1, the distance L between the two bending pieces 14 is larger than the outer diameter of the bolt 2, a plurality of separating washers 3 are sleeved on the bolt 2, the separating washers 3 are symmetrically sleeved on the bolt 2 from top to bottom, an indicating washer 15 is arranged between the bolt 2 and the bending piece 14 on the lower clamping plate 12, the indicating washer 15 is an incomplete circular washer, the outer diameter of the indicating washer 15 is larger than the distance L between the two bending pieces 14, the upper end of the bolt 2 is connected with a nut 4 in a matching way, and the nut 4 is arranged on the upper clamping plate 11.
The working condition is as follows: as shown in fig. 1 and fig. 2, the two fire-resistant bus ducts 5 are respectively inserted into the left and right sides of the joint device until the limiting blocks 13 inside the clamping plates 1 abut against the bus duct cover plate, the tapping units 52 of the two fire-resistant bus ducts 5 are connected, at this time, the bolts 2 are screwed by using a wrench (not shown in the figure), the bolts 2 drive the upper clamping plate 11 and the lower clamping plate 12 to squeeze inwards until the bolt heads on the bolts 2 break and the indicating washers 15 fall off from the bolts 2, which indicates that the joint device has reached the optimal connection state. The connector device abandons the traditional structural design, ensures that the phenomenon of bus duct disconnection can not occur in the whole connection process, simplifies the installation process and improves the installation speed between bus ducts.
It should be noted that the bolt head after installation can be used for a second time in the later maintenance and dismounting process, and the waste of installation elements is not caused.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
