Above-described caliberating device 100, three boundaries are set on warning portal 1 simultaneously, when operating mode, can generate standard gauge S0, one-level gauge S1, secondary gauge S2 automatically, can carry out the demarcation of standard gauge, one-level gauge, secondary gauge simultaneously to safety door thus; Adopt Fu 2, the accurately revolution of controlling and driving motor (rotational angle); By transmission device 3, realize the warning portal 1 straight-line conversion that rotatablely moves of drive motor easily.Thus, under the control of Fu 2, can accurately control the flexible stroke of warning portal 1, guarantee standard gauge S0, one-level gauge S1, the secondary gauge S2 of its generation shape, be of the required size, reduce systematic error, improve stated accuracy to safety door.

In order to reduce field installation time, to improve and demarcate efficient, above-mentioned caliberating device 100 can be installed on a kind of special vehicle, to have formed movably railway freight safety door caliberating device, below be called railway freight safety door calibration vehicle (being designated hereinafter simply as calibration vehicle) 200, be described below.

Please also refer to Fig. 7 A, Fig. 7 B, wherein, Fig. 7 A is the scheme drawing (main looking) of the utility model railway freight safety door calibration vehicle; Fig. 7 B is the birds-eye view of railway freight safety door calibration vehicle after removing the part assembly among Fig. 7 A.This calibration vehicle 200, caliberating device 100 in its car body, are used for safety door is demarcated.Be cost saving, the car body of calibration vehicle 200 can be by the multiple vehicle transformation of the way; Preferably, adopt the general-purpose box car transformation to form, its car body is made up of underframe, side wall, headwall, roof.This box car itself is a kind of railway truck, and its retrofit work amount is little, and can simulate the running environment of railway freight realistically.

As shown in Figure 7, the railway freight safety door is demarcated dress and is thrown aside and 100 be installed in underframe 21; Above this installation site, false ceiling 22 is set; On the side wall of these both sides, installation site, side door 23 is installed respectively.

After false ceiling 22, side door 23 were set, the warning portal 1 in the caliberating device 100 can stretch freely, that is, upper control limit door 1-1, left warning portal 1-2, right warning portal 1-3 are recoverable to car body, also can rise to the gauge height; Simultaneously, left warning portal 1-2, right warning portal 1-3 can also carry out the flexible stroke of horizontal direction.When operating mode, false ceiling 22 and two side doors 23 are opened, by Fu 2, just warning portal 1 can be stretched over mutually deserved size positions, and generate complete standard gauge S0, one-level gauge S1, secondary gauge S2, and then finish the demarcation of safety door.

Especially, for guaranteeing warning portal 1, particularly left warning portal 1-2, right warning portal 1-3 do not interfere with doorframe 24 in telescopic process, should keep certain interval between warning portal 1 and the doorframe 24; Especially, should keep bigger gap respectively between the top chord of left warning portal 1-2, right warning portal 1-3 and doorframe 24, be generally about 145mm.

The unlatching of described false ceiling 22 and/or side door 23, close, can adopt manual type or mechanical system to carry out; Preferably, false ceiling 22 and/or side door 23 adopt open loop control, to reduce labor intensity.Simultaneously, described false ceiling 22 and/or side door 23 can adopt the version of revolving door, also can adopt the version of sliding door; Preferably, adopt the version of sliding door, so that utilize the electric control system of aforementioned Fu 2.In this case, as long as increase a control branch road, and needn't the otherwise designed controlling schemes, specific as follows stating:

As shown in Figure 5, in Fu 2, set up sliding door control branch road, comprise, sliding door servomotor 2-1-4 is used to export false ceiling 22, side door 23 unlatchings or closes required power; Sliding door servo-driver 2-2-4, the rotational angle of adjustment sliding door servomotor 2-1-4 rotor; Sliding door is opened sensor 2-3-9, sliding door returns zero deceleration sensor 2-3-10, sliding door closure sensor 2-3-12, is respectively applied for detected activity ceiling 22, side door 23 at the position signal of opening, returning under zero deceleration, the closed condition.Sliding door servomotor 2-1-4 by sliding door transmission device 3-4, just can open or close false ceiling 22, side door 23 after starting.

Especially, adopt Fu 2 shown in Figure 5 after, warning portal 1 can be realized interlock protection with false ceiling 22, side door 23.As false ceiling 22 and/or side door 23 is not opened or the aperture deficiency, warning portal 1 can be not protruding, prevents that thus warning portal 1 and side door 23 or false ceiling 22 from bumping damage equipment.

This calibration vehicle 200 is installed caliberating device 100 on existing vehicle technology basis, make caliberating device 100 can arbitrarily move to any safety door position, promptly becomes a kind of removable caliberating device; Thus, need not on-site installation, debugging, save the nominal time, improve and demarcate efficient.

The above only is a preferred implementation of the present utility model, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, and protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
