Detailed description of the invention
Core of the present utility model is to provide a kind of rail wagon base frame and brake activation valve flap seat thereof, and the reliability of this brake activation valve flap seat is high, long service life, and is convenient to the dismounting of brake activation valve.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
It should be noted that for ease of understanding and saving space, be below described in conjunction with rail wagon base frame and brake activation valve flap seat thereof, the railway truck providing for the utility model, describes no longer separately, and beneficial effect also no longer repeats to discuss.
Described rail wagon base frame comprises underframe body and is fixedly arranged on the brake activation valve flap seat of described underframe body.
Please refer to Fig. 4-5, Fig. 4 provides the structural representation of a kind of detailed description of the invention of brake activation valve flap seat for the utility model; Fig. 5 is the birds-eye view of Fig. 4.
In a kind of specific embodiment, the brake activation valve flap seat of described rail wagon base frame comprises boatswain chair 22 and two bearings 21; Wherein, two bearings 21 be arranged in parallel, and boatswain chair 22 is positioned at the upper end of two bearings 21, and removably connect with two bearings 21, and the upper end of boatswain chair 22 is also connected with hanger 23, and hanger 23 has hole for hoist 23a; In addition, on boatswain chair 22, also offer the mounting hole 22a that brake activation valve is installed.
This brake activation valve flap seat is fixedly arranged on described underframe body by bearing 21.Particularly, bearing 21 can be welded in to described underframe body, easy to be reliable.Certainly, also can adopt other affixed mode.
Because the bearing 21 of this brake activation valve flap seat removably connects with boatswain chair 22, avoid the integral assembly welding structure of brake activation valve flap seat in background technology, reduce the weld seam quantity of brake activation valve flap seat, in the operational process of railway truck, reduce the probability of brake activation valve flap seat generation endurance crack, thereby improve the reliability of brake activation valve flap seat, extended the service life of brake activation valve flap seat.
When brake activation valve is installed, can make boatswain chair 22 and bearing 21 in notconnect state, first brake activation valve is installed on to boatswain chair 22, recycling hanging device is placed in boatswain chair 22 and mounted brake activation valve on bearing 21 by the hole for hoist 23a of hanger 23, finally boatswain chair 22 is connected with bearing 21; Dismounting is when brake activation valve, can first remove being connected of boatswain chair 22 and bearing 21, recycle the hole for hoist 23a of hanging device by hanger 23 by boatswain chair 22 and on brake activation valve hang bearing 21, finally unload brake activation valve.Obviously, in this process, the installation or removal of brake activation valve and boatswain chair 22 all can not carried out in the bottom of railway truck, that is to say, are not limited to the bottom space of railway truck, thereby have improved the simplicity of brake activation valve dismounting.
In concrete scheme, hanger 23 can be fixed in boatswain chair 22 by welding manner, easy to be reliable.Certainly, also can by other means hanger 23 be fixed on boatswain chair 22 when actual setting.
In scheme, hanger 23 is arranged at the middle part of boatswain chair 22 more specifically, so, in the time utilizing hanging device lifting boatswain chair 22, can make its stress equalization.
In this embodiment, hanger 23 is structure triangular in shape roughly, and as shown in Figure 8, hole for hoist 23a is opened in the medium position of hanger 23, when lifting, can make its stress balance.
The structure that should be appreciated that hanger 23 is not limited to triangle, also can be set to semicircle grade for other structures, as long as can realize the lifting of boatswain chair 22.
Please also refer to Fig. 6, Fig. 6 is the structural representation of bearing in Fig. 4.
In this embodiment, bearing 21 comprises crossbeam 211 and two vertical beams that be arranged in parallel 212, and crossbeam 211 is fixed in the upper end of two vertical beams 212, that is to say, bearing 21 is substantially in shaped door; The two ends of boatswain chair 22 are connected with two crossbeams 211 of two bearings 21 respectively.
In concrete scheme, the cross-sectional plane of crossbeam 211 and vertical beam 212 is all L-shaped, so can save material.Certainly, under the prerequisite of proof strength and rigidity, crossbeam 211 and vertical beam 212 also can be selected other structures, as its cross-sectional plane can be the degree of lip-rounding etc.
Particularly, the connection between crossbeam 211 and vertical beam 212 can adopt welding manner, not only easy but also reliable.Certainly, also can adopt the bending of a beam body to form described crossbeam 211 and described vertical beam 212.
Please also refer to Fig. 7, Fig. 7 is the structural representation of boatswain chair in Fig. 4.
In this embodiment, offer bolt hole 22b on boatswain chair 22, boatswain chair 22 removably connects by bolt with crossbeam 211, convenient and reliable.Certainly,, when actual setting, also can adopt other modes that removably connect.
On boatswain chair 22, also offer mounting hole 22a, for brake activation valve is installed.In this programme, on boatswain chair 22, offer four mounting hole 22a, when actual setting, also can offer as required the mounting hole 22a of other numbers, as long as guarantee that brake activation valve is connected with the reliable of boatswain chair 22.
Further, in two bearings 21, the distance between two vertical beams 212 of one is greater than the distance between two vertical beams 212 of another one, and as shown in Figure 5, the distance between two vertical beams 212 of left side bearing 21 is greater than the distance between two vertical beams 212 of right side bearing 21.
Because a side of brake activation valve also has the pipeline being connected with other relevant devices, as above arrange, when brake activation valve is installed, can make brake activation valve there are a side and two left side bearing 21 homonymies of connecting line, so, be convenient to the layout of brake activation valve connecting line.
When actual setting, can determine as required the distance between two vertical beams 212 of bearing 21.
It is pointed out that on the noun of locality relating to herein, left and right etc. is to be all arranged in figure and parts position each other defines with parts in Fig. 4 to Fig. 8, just in order to explain the clear and convenient of technical scheme.Should be appreciated that the use of the described noun of locality should not limit the protection domain of the application's request.
Above a kind of rail wagon base frame provided by the utility model and brake activation valve flap seat thereof are all described in detail.Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
