Abstract
Disclosed is a pressure measurer for train which relates to a pressure detector and has particular application to the detection of the wind pressure of the main blast pipe of passenger train and cargo train in railway. The utility model comprises a pressure measuring block, a clamping mechanism and a pressure gauge. The screw pressure measuring block is in the shape of a round disk. The bottom part of the pressure measuring block is provided with a protruded round table which is corresponding to the hole of a connector, the middle of the pressure measuring block is provided with thread holes which are connected with screw joints, and the outside of the pressure measuring block is provided with a pin hole which is connected with a clamping mechanism. The clamping mechanism is a lever eccentric clamping mechanism which is composed of a handle, a pressure measuring hook and a circlip pin shaft. The inlet of the pressure gauge is provided with pressure buffering screws, and the center of the screws are provided with stepped fine holes. The utility model has the advantages of small size, light weight, high safety and convenience for carrying.
Description
The utility model relates to that a kind of pressure detector is specially adapted to the detection of railway visitor, lorry air main blast and to the check and correction of its car apoplexy table.
China railways visitor, the detection of lorry air main blast and the check and correction of car apoplexy table at present do not have special testing instrument, be to adopt homemade instrument, at the hose end of air hose coupling a tensimeter is installed, this instrument heaviness, detection efficiency are low, do not reach measuring accuracy.Hurt sb.'s feelings easily and the damage instrument owing to pressure jump during dismounting.
The purpose of this utility model is the shortcoming that overcomes above-mentioned self-made tool, and a kind of be used for measuring visitor, lorry air main blast size are provided, and visitor, lorry wind table are proofreaded the specially-used measuring instrument of measuring.
The technical solution of the utility model is achieved in that the train manograph is stifled by pressure measurement, clamp system, tensimeter are formed: disc is blocked up in pressure measurement, the bottom has the round platform of protrusion corresponding with the hole of connector, the centre has threaded hole to connect with tensimeter spiral shell button, and there is the pin hole that links to each other with clamp system in its outside; Clamp system is by the eccentric clamp system of the lever that handle, pressure measurement are colluded, jump ring, bearing pin are formed; Manometric porch is equipped with the pressure buffer screw, and there is a stepped appearance pore at the screw center.
The utility model is compared with existing self-control pressure measurement instrument has that volume is little, in light weight, test is easy to loading and unloading, it is safe in utilization to be easy to carry, under the situation of airduct supercharging, release and pressure jump, make tensimeter avoid impacting, thereby prolonged advantage such as manometric serviceable life.
Now describe most preferred embodiment of the present utility model in conjunction with the accompanying drawings in detail.
Fig. 1 is the scheme of installation of train manograph
Fig. 2 is the vertical view of train manograph
Fig. 3 is the left view of train manograph
Fig. 4 installs partial enlarged drawing for buffer screw
The train manograph is stifled by pressure measurement, clamp system, tensimeter are formed: 5 one-tenth discs are blocked up in pressure measurement, the bottom has the round platform of protrusion corresponding with the hole of connector 12, the centre has threaded hole to connect with tensimeter 3 spiral shell buttons, and there is the pin hole 13 that links to each other with the handle 2 of clamp system in its outside; Clamp system is by handle 2, pressure measurement collude 1, jump ring 7, bearing pin 6 etc. are formed the eccentric clamp system of lever; The porch of tensimeter 3 is equipped with pressure buffer screw 11, there is a thin through hole at the screw center, the hole is a stepped appearance, most advanced and sophisticated and bottom part aperture diameter respectively is φ 0.5mm, φ 2mm, pressure wind has slowed down the air pressure of turnover tensimeter 3 through buffer screw 11, under the situation of supercharging, release and pressure jump, make tensimeter 3 avoid impacting, thereby prolonged the serviceable life of tensimeter 3.In order to improve the sealing that connects of tensimeter 3 and pressure measurement stifled 5, in its connection place groove, place sealing gasket 4.Clamp system is by the eccentric clamp system of lever that handle 2, pressure measurement collude 1, jump ring 7, bearing pin 6 are formed, and on the handle stifled 8 for ease of the end of leaving handle 2 in, be provided with and hang pin 10, link 9 is installed on pin.
Pressure measurement stifled 5 and pressure measurement are colluded 1 and are all adopted the enhancing nylon 1010, and tensimeter 3 adopts φ 60,0～1000KPa, 1.5 stage pressure tables 3, and handle 2 adopts A
3Cold drawn weldless steel tube bends and forms.
Last plane with the pressure measurement of manograph stifled 5 during use is placed in the hose coupling 12 top tongues, make stifled 5 end round platforms of pressure measurement put into the hole of hose coupling 12, then pressure measurement being colluded 1 colludes on the edge, base of connector 12, after being close to handle 2 has been removed, make its state as shown in Figure 1, then with car upcast ventilation pipe valve open, pressure wind enters tensimeter 3 and measures behind buffer screw 11.
Claims (3)
1, the train manograph is used for the detection of railway visitor, lorry air main blast and to the check and correction of car apoplexy table, it is characterized in that it is stifled by pressure measurement, clamp system, tensimeter formed: disc is blocked up in pressure measurement, the bottom has the round platform of protrusion corresponding with the hole of connector, the centre has threaded hole to connect with tensimeter spiral shell button, and there is the pin hole that links to each other with clamp system in its outside; Clamp system is by the eccentric clamp system of the lever that handle, pressure measurement are colluded, jump ring, bearing pin are formed; The pressure buffer screw is equipped with in manometric porch, and there is the stepped appearance pore at the screw center.
2, train manograph according to claim 1 is characterized in that pressure measurement is blocked up and all employing enhancing nylon material manufacturings are colluded in pressure measurement.
