Detailed Description
The utility model provides a frock is connected to railcar coupler gas circuit can external model be the coupling of airtight type 330, and this coupling is using widely in partial circuits such as fertile full circuit and shanghai, nanjing, guangzhou, chengdu at present, and this frock is applicable to and uses all circuit trains of this hook type in the above-mentioned urban circuit.
The semi-permanent coupler of the tight-lock type 330 is divided into a male rod and a female rod, and please refer to fig. 2 and 4. Due to the difference between the male and female poles, when the train is connected, the female pole connector 42 and the male pole connector 40 are inserted together, so that the gas passage is communicated. However, in the process of subway erection repair, due to the separation of the male rod and the female rod, the coupler gas circuit connection tool needs to be designed to realize the connection and conduction of the gas pipeline. In view of the difference of public pole, female pole structure, in order to realize better assembly, the utility model provides a frock is connected to two kinds of coupling gas circuits, its public pole and the female pole that corresponds airtight type 330 couplers respectively, following difference detailing.
Example 1
As a first embodiment of the present invention, please refer to fig. 1, the coupler gas circuit connection tooling of the present embodiment mainly comprises a bottom plate 10, a mounting plate 11, a supporting plate 12, a clamping plate 13, a clamping head 20, a connecting screw 21, a connecting plate 23 and a rotation adjusting block 30.
The mounting plate 11, the supporting plate 12 and the engaging plate 13 are arranged in parallel and mounted on the bottom plate 10, and the supporting plate 12 is disposed between the mounting plate 11 and the engaging plate 13. The bayonet 20 and the connection plate 23 are respectively installed at both ends of the connection screw 21. The rotary adjusting block 30 is screw-mounted on the connecting screw 21.
One end of the clamping connector 20 is used for assembling an airflow pipeline so as to connect with an external air source. The middle parts of the clamping head 20, the connecting screw 21 and the connecting plate 23 are provided with an air flow pipeline which penetrates out of the middle part of the connecting plate 23.
After the assembly is completed, the connecting screw 21 penetrates through the mounting plate 11 and the support plate 12, the rotation adjusting block 30 is located between the mounting plate 11 and the support plate 12, and the gap between the mounting plate 11 and the support plate 12 is slightly larger than the thickness of the rotation adjusting block 30. The connecting plate 23 is located between the supporting plate 12 and the engaging plate 13, and the rotation of the rotation adjusting block 30 drives the connecting screw 21 to rotate and move horizontally, so as to adjust the distance between the connecting plate 23 and the engaging plate 13.
The clamping plate 13 is provided with an arc-shaped groove with an upward opening, and the clamping plate 13 is used for assembling the gas circuit connecting tool with a male rod or a female rod of the close-lock type 330 coupler. Referring to fig. 2, since the male rod connector 40 is externally designed with a boss 41, the engaging plate 13 is conveniently mounted on the riding way, and the end of the male rod connector 40 is recessed towards the inner side (which is convenient for the insertion and mounting of the female rod connector 42), when the air path connecting tool is mounted on the male rod, the connecting plate 23 is adjusted by rotating the rotary adjusting block 30 until the connecting plate is inserted into the inner side of the end of the male rod connector 40, and a tight fit relationship is formed.
Because the male rod connector 40 is communicated with the air pipe 50, after the air path connecting tool is assembled, the air path can be conducted, and an external air source can supply air to the train for testing.
Example 2
As a second embodiment of the present invention, please refer to fig. 3, the main structure of which is the same as the first embodiment, and is only modified for assembling the female rod of the coupler 330.
Referring to fig. 4, since there is no boss on the female rod connector 42, only one mounting groove 43 is provided on each of the upper and lower sides thereof, for the female rod connector, the gas circuit connecting tool needs to be rotated by 90 ° for assembly, and the engaging plate 13 is engaged in the upper and lower mounting grooves 43. By rotating the rotary adjusting block 30, the connecting plate 23 is adjusted until it abuts against the end of the female rod connector 42 and forms a tight fit.
The lower part of the female rod at the female rod connector 42 is provided with a structural connector 44 (in a splayed shape), so that the assembly of the air path connecting tool can be prevented. Therefore, in the present embodiment, the hollow-out inclined grooves 14 are formed at the corresponding positions of the bottom of the one side of the engaging plate 13 and the bottom plate 10 on the same side, so that the gas circuit connecting tool is assembled to avoid the structural connecting member 44.
Because female pole connector 42 communicates with trachea 50, consequently, after the frock is connected to the gas circuit assembly, can realize that the gas circuit switches on, external air supply can be to the train air feed in order to test.
The foregoing is merely exemplary and illustrative of the principles of the present invention, and various modifications, additions and substitutions as may be made to the specific embodiments described herein by those skilled in the art are intended without departing from the spirit and scope of the invention as defined in the accompanying claims.
