Abstract
A multi-connection valve connecting device is provided to prevent the safety hazard caused by driver's failure when shifting the switch part of the multi-connection valve to the corresponding position during the switching process, and to enhance the informatization of position transition of the multi-connection valve. The multi-connection valve comprises a switch valve part, a multi-connection valve part, a brake cylinder shut-off valve part, a multi-connection valve body, and a valve seat. A signal output port is equipped on the multi-connection valve body and a pressure switch is arranged in the signal output port. When the multi-connection valve is conducted in the 'primary machine position' or 'assistant machine position', the position transition is converted into electrical signals which are further input to a microcomputer and the microcomputer monitors with the aid of logical programs to avoid the safety hazard when the driver forgets to shift the switch of multi-connection valve during the terminal-switching process.
Description
Technical field
The utility model relates to a kind of preassembling of locomotive electro-pneumatic brake, is that the heavy multi pack of double-heading valve of a kind of two-shipper that is used for railway transportation and multiple-operated locomotive units traction is put specifically.
Background technology
For adapting to the continuous growth of railway transporting amount, railway transportation adopts two-shipper and multiple-operated locomotive units traction through regular meeting.At dress with the locomotive electro-pneumatic brake of DK1 type or JZ7 type and require to need to adopt double-heading valve weight multi pack to put in the electric locomotive that air brake heavily joins.Double-heading valve is made up of change-over valve portion, double-heading valve portion and brake cylinder intercepter valve (IV) portion and double-heading valve body, base.Change-over valve portion is a manually operated valve, demonstrates two active positions of double-heading valve on the nameplate: this seat in the plane and assisting vehicle position.Switching button remains on a certain fixed position under the effect of spring and locating dowel pin, if need dislocation, must earlier switching button be pushed inward, and then rotate 180 °.Behind the desired position, unclamp.Because the rotation energy of switching button drives the rotation of eccentric rod, and eccentric rod is that vertical direction is connected with plunger, the rotation of eccentric rod has become moving up and down of plunger, by the sealing function that the O shape on the plunger is enclosed, has realized opening or breaking of two paths.During this seat in the plane, two paths are obstructed, and wherein underpass and atmosphere are linked up; During the assisting vehicle position, two paths are linked up.When the binodal electric locomotive heavily joins when handling, must with change-over valve artificial get to corresponding position.The control node locomotive is got to " this seat in the plane ", and multi-locomotive is got to " assisting vehicle position ", then could guarantee the transportation safety of driving a vehicle.If the driver forgets that the double-heading valve change-over swith is carried out corresponding conversion will bring transportation safety hidden danger when changing joint manipulation locomotive.Table 1 has been listed the consequence that produces at diverse location
Table 1
| Sequence number | Handle the locomotive double heading valve position | Multi-locomotive double-heading valve position | Produce consequence |
| 1 | This seat in the plane | The assisting vehicle position | Effect is normal |
| 2 | This seat in the plane | This seat in the plane | When handling the little lock brake application of this section locomotive, multi-locomotive is brake application not; Handle when needing to alleviate after the big lock of this section locomotive is braked, the multi-locomotive brake cylinder is not alleviated substantially, causes and relaxes. |
| 3 | The assisting vehicle position | This seat in the plane | When handling the little lock brake application of this section locomotive, multi-locomotive is brake application not; Handle when needing to alleviate after the big lock of this section locomotive is braked, influenced by electropneumatic valve path latus rectum, the multi-locomotive brake cylinder is not alleviated substantially, causes and relaxes. |
| 4 | The assisting vehicle position | The assisting vehicle position | When handling the little lock brake application of this section locomotive, brake cylinder brake application speed is slow, and multi-locomotive can be slower; When handling the big lock of this section locomotive, locomotive brake cylinder pressure and train pipe pressure reduction are disproportionate, are much smaller than normal condition. |
As can be seen from the above table,, if the driver forgets that the double-heading valve change-over swith is carried out corresponding conversion will bring transportation safety hidden danger when changing joint manipulation locomotive.Therefore necessary this is improved.
The utility model content
The purpose of this utility model is in order to solve the deficiency of present double-heading valve, a kind of double-heading valve of performance safety and reliability to be provided.
The purpose of this utility model is achieved through the following technical solutions: in order to prevent that the driver from when changing the joint manipulation, forgetting the converter section of double-heading valve is got to the potential safety hazard that bring corresponding position, need improve double-heading valve, strengthen its position transitional informationization.Double-heading valve comprises change-over valve portion, double-heading valve portion and brake cylinder intercepter valve (IV) portion and double-heading valve body, base, total wind connection pipe that the following square tube of double-heading valve cage saddle and bridle a horse is flow through by change-over valve portion.When the assisting vehicle position, the wind of total wind connection pipe arrives the lower surface of cage saddle and bridle a horse.A signal output is set on the flange face of double-heading valve body, and total wind connection pipe trench of signal output and double-heading valve cage saddle and bridle a horse below is logical.At signal output the electric signal generating means is housed, the electric signal generating means becomes electric signal with the blast of signal output and is input to microcomputer.The electric signal generating means can be a kind of pressure switch, pressure switch is installed in outside the signal output, pressure switch can be exported a signal by signal wire (SW), and at the operation double-heading valve when " this seat in the plane " or " assisting vehicle position ", with the position transitions is electric signal, when double-heading valve was in " this seat in the plane ", because signal output does not have blast, output signal was " 0 "; When being in " assisting vehicle position ", signal output has blast, and output signal is " 1 ".Pressure switch also is input to microcomputer with this signal, utilizes program logic computer to control, and avoids the driver when changing the end operation, because of forgetting that the double-heading valve change-over swith carries out corresponding conversion and will bring transportation safety hidden danger.
The utility model is implemented with machine monitoring the present position of double-heading valve by electric signal, can effectively avoid because of the driver when changing the end operation, because of forgetting that the double-heading valve change-over swith carries out corresponding conversion and will bring transportation safety hidden danger.And implement simply, on existing double-heading valve,, just can realize the informationization of double-heading valve function conversion through transforming, avoid the driver operation mistake.
