Abstract
The utility model discloses a device hanging mechanism of a railway car; the extrution processing technique of the profile of the crossbeam of a bottom frame is directly adopted on the hanging and transverse moving positions at the lower side of the crossbeam, thus avoiding welding relevant mounting seats on the crossbeam; not only the mounting technique is simplified and the position aligning accuracy is improved; but also the space occupied by the hanging device is correspondingly reduced. The utility model includes a hanging slot arranged on the crossbeam of the bottom frame; the bolt head of a hanging bolt is arranged in the hanging slot and the screw rod of the hanging bolt vertically extends to the lower side. The hung devices are arranged on the lower side of the hanging bolt from up to down through fastening nuts. The utility model is characterized in that the hanging bolt can transversely move along the hanging slot to arrange the hanging slot on the crossbeam so as to avoid welding the mounting seats on the crossbeam. The selection of the hanging position of the devices can be conveniently realized through moving the hanging bolt, thereby simplifying the mounting technique of the devices and being beneficial to improving the aligning accuracy as well.
Description
Technical Field
The utility model relates to a quick-witted mechanism is hung to equipment, is applied to rail vehicle's vehicle bottom equipment specifically and hangs belongs to the machine-building field.
Background
On rail vehicles which are currently put into use, large-scale power control equipment, air conditioning equipment, water tanks, sewage tanks, brake control equipment and the like are generally placed below a vehicle body underframe.
With the continuous improvement of the performance design of high-speed rail vehicles, more and more devices are mounted at the bottom of the vehicle, and how to realize the maximization of the internal space of the vehicle body and the design requirement of reducing the gravity center of the vehicle body on the premise of mounting the devices as much as possible is always a difficult problem of mounting the devices under the vehicle.
SUMMERY OF THE UTILITY MODEL
Rail vehicle is with equipment hanging mechanism, its design aim at solve above-mentioned problem and adopt hanging and lateral shifting device in the crossbeam below, directly borrow the extrusion process of chassis crossbeam section bar, avoid welding relevant mount pad on the crossbeam, both realized simplifying mounting process, improve the position alignment accuracy, reduced the shared space of cable suspension device again correspondingly.
In order to achieve the above design purpose, the device hanging mechanism comprises:
the bolt head of the hanging bolt is arranged in the hanging groove, and the screw rod of the hanging bolt vertically extends downwards.
The hung equipment is arranged below the hanging bolt from bottom to top through the fastening nut.
According to the technical scheme, the hanging bolt can move transversely along the hanging groove, and the hanging groove is arranged on the cross beam, so that the mounting seat is prevented from being welded on the cross beam. Through the movement of the hanging bolt, the selection of the hanging position of the equipment can be conveniently realized, thereby simplifying the installation process of the equipment and being beneficial to improving the alignment precision.
The further improvement scheme is that the hanging groove is integrally extruded and formed, and a placing hole for placing a hanging bolt is formed below the hanging groove.
In order to improve the integral fastening performance of the hanging mechanism, a contact gasket is arranged at the head of the hanging bolt. A pinch plate is buckled on the underframe beam and is tightly connected with the contact gasket through a small bolt.
Before the equipment is installed, a hanging bolt and a contact gasket need to be placed in a placing hole of a hanging groove, and positioning is realized through transverse movement in the hanging groove;
then, the buckle plate and the small bolt are screwed down to fix the hanging bolt;
and finally, stably lifting the equipment by a crane, aligning with the hanging bolt, and screwing the locking nut.
As mentioned above, the equipment hanging mechanism for the rail vehicle has the advantages that the extrusion processing technology of the cross beam profile of the underframe is directly used to avoid welding the related mounting seats on the cross beam, the equipment mounting technology is simplified, the alignment precision of the fixed position can be improved, and the occupied space of the hanging device is correspondingly reduced.

The direction of the arrow in fig. 3 indicates the operation direction of inserting the hanger bolt.
Detailed Description
the bolt head of the hanging bolt 2 is arranged in the hanging groove 11, and the screw rod of the hanging bolt extends vertically downwards.
The suspended equipment 7 is installed below the suspension bolt 2 from the bottom to the top through a fastening nut 6.
The hanging groove 11 is formed by integral extrusion, and a placing hole 12 for placing the hanging bolt 2 is arranged below the hanging groove.
A contact gasket 4 is arranged at the head of the hanging bolt 2, and the pinch plate 3 is buckled on the underframe cross beam 1 and is tightly connected with the contact gasket 4 through a small bolt 5.
Before the installation of the device 7, the hanger bolt 2 together with the contact pad 4 is placed in the hanger groove 11 in the direction of the arrow in fig. 3, and then moved to a desired position.
When the equipment 7 is installed, the equipment is stably supported by a crane, the installation hole penetrates through the hanging bolt 2, and the fastening nut 6 is used for screwing.
