Abstract

The utility model discloses a perceptive carrying device which can be used for monitoring the unbalanced stress of a supporting head of each unwheeling machine at any time. The perceptive carrying device comprises a drive screw rod (1) which can rotate, a nut (2) arranged on the drive screw rod (1) and a supporting head (3) pushed by the nut (2). Importantly, a pressure sensor (4) is arranged between the nut (2) and the supporting head (3), and is connected with a programmable controller (5).The utility model has the advantages of simple structure, reasonable design, convenient operation and reliable and safe use; and the perceptive carrying device is used for overhauling railway rolling stocks and motor train units, and has wide application range.

Description

A kind of perception bogey

Technical field:

The utility model relates to rolling stock's docking facility, particularly is the perception bogey of a kind of rolling stock car lifting J-Horner.

Technical background:

Car lifting J-Horner is the indispensable equipment of rolling stock's maintenance, its effect is not understand at the permutation motor train unit to need under the situation about compiling by many scaffold cars machine car body to be erected synchronously, so that bogie truck is overhauled and changed in the car body bottom, the safety of unwheeling operation is all in all major issue, in case the load inequality of car lifting J-Horner holder head takes place, just the vehicle capsizing case may take place, the influence safety in production, and the synchronous error scope of the holder head of existing car lifting J-Horner is big, in the unwheeling operation process, can not in time find a holder off-load of indivedual car lifting J-Horners, lose the situation of carrying or transshipping, cause job safety hidden danger.

Summary of the invention:

Goal of the invention of the present utility model provides a kind of perception bogey of discontinuity equalization of the holder head that can monitor each car lifting J-Horner in the unwheeling process at any time.

Realize that technical solution of the present utility model is as follows: comprise rotatable motion turn-screw, be installed in the holder head that nut on the turn-screw and nut promote, key is to be provided with a pressure sensor between nut and the holder head, and pressure sensor is connected with a Programmable Logic Controller.

Be connected for wired connection or wireless signal between described pressure sensor and the Programmable Logic Controller.

The utility model is simple in structure, and is reasonable in design, easy to operate, uses reliable and securely, and is used for the maintenance of rail vehicles and motor train unit, applied range.

Description of drawings:

Fig. 1 is an integral structure scheme drawing of the present utility model.

The specific embodiment:

See also Fig. 1, specific embodiment of the utility model is as follows: comprise rotatable motion turn-screw 1, be installed in holder that nut 2 on the turn-screw 1 and nut 2 promote 3, key is to be provided with a pressure sensor 4 between nut 2 and the holder 3, and pressure sensor 4 is connected with a Programmable Logic Controller 5; Pressure sensor 4 and Programmable Logic Controller 5 are prior art, pressure sensor 4 optional resistance strain gages of using for example, the screw thread of turn-screw 1 and nut 2 is an Acme thread, Acme thread possesses auto-lock function, can stop and locking at an arbitrary position, nut 2 is connected also support holder 3 with holder 3, the top of holder 3 also has a holder attaching parts 6,4 of pressure sensors are arranged between a holder attaching parts 6 and the nut 2, be connected for wired connection or wireless signal between pressure sensor 4 and the Programmable Logic Controller 5, pressure sensor 4 and Programmable Logic Controller 5 have constituted the load monitoring device of the holder 3 of car lifting J-Horner, can directly demonstrate load value in the holder 3 by Programmable Logic Controller 5; When car lifting J-Horner is worked under the unwheeling operating mode, turn-screw 1 rotatablely moves and promotes holder 3 lifting by nut 2 and pressure sensor 4, after holding vehicle, holder 3 makes pressure sensor 4 pressurizeds by attaching parts 6, pressure sensor 4 is transferred to Programmable Logic Controller 5 with the pressure value of impression, Programmable Logic Controller 5 directly shows the load value in the holder 3, at any time monitor hidden danger in the unwheeling process according to the load value in the holder of each car lifting J-Horner 3, if each holder 3 load value that Programmable Logic Controller 5 shows are all basic identical, show that then all car lifting J-Horners carrying row and each holder synchronously all 3 is in state of equilibrium, if holder 3 off-load of one or more car lifting J-Horner wherein, lose and carry or overload, 5 pairs of off-loads of Programmable Logic Controller, losing the car lifting J-Horner that carries or transship regulates and control, make holder 3 a maintenance state of equilibrium of all car lifting J-Horners, guarantee the unwheeling job safety.

Claims

1. perception bogey, comprise rotatable motion turn-screw (1), be installed in the holder head (3) that nut (2) on the turn-screw (1) and nut (2) promote, it is characterized in that being provided with a pressure sensor (4) between nut (2) and the holder head (3), pressure sensor (4) is connected with a Programmable Logic Controller (5).

2. by the described perception bogey of claim 1, it is characterized in that being connected for wired connection or wireless signal between described pressure sensor (4) and the Programmable Logic Controller (5).
