Background
At present, due to the convenient installation mode and the low cost, the i-steel rail trolley has a large number of applications in an automobile manufacturing factory, such as transferring workpieces from one station to another station, or conveying parts to a production line or a warehouse along a fixed rail, and the position of the i-steel rail trolley needs to be fed back to a control system in the running process of the trolley.
The inventor finds out that the following two main methods are adopted in the process of realizing the utility model:
1. a detection switch is arranged at a fixed position of the track, and the detection switch feeds back to a control system after detecting the trolley;
2. the trolley walking motor adopts a servo motor or other driving devices with position feedback capacity, and the trolley position information is fed back in real time through the driving motor of the trolley;
however, both of these solutions have drawbacks: in the scheme 1, more detection switches are required to be equipped when the position requirements are more, so that the control difficulty and the failure rate are increased; scheme 2 is with higher costs, and the dolly probably skids when walking on the I-steel track wheel moreover, and servo motor judges the position through the number of turns of record wheel rotation, and the position of feedback will be inaccurate when the wheel skids.
Disclosure of Invention
In order to solve the technical problem who exists among the current I-steel small rail car position feedback, the utility model provides an I-steel small rail car position feedback device with low costs, high reliability.
Therefore, the technical scheme of the utility model is, a I-steel small rail car position feedback device, including small rail car and I-steel track, its characterized in that:
a chain support extends from one side surface of the I-shaped steel track in the vertical direction, a chain is connected to the chain support along the length direction of the I-shaped steel track,
the utility model discloses a rail trolley, including the small rail car, be fixed with the mounting panel that upwards extends the setting on the small rail car, wear to be equipped with the pivot of rotation connection on the mounting panel, pivot one end is fixed with the sprocket with chain looks meshing, the pivot other end is connected with the encoder, the encoder is fixed in on the mounting panel through the support, be located the mounting panel of encoder below and be fixed with wireless communication module, the encoder is connected through the data line with wireless communication module, wireless communication module is connected through wireless communication with control system.
Preferably, the mounting plate is provided with a rotating shaft in a penetrating manner, the rotating shaft is rotatably connected, the mounting plate is embedded with a bearing, and the rotating shaft penetrates through and is fixed in a through hole in the middle of the bearing in a limiting manner.
The technical scheme is further improved in that spacer bushes abutted with the inner ring of the bearing are respectively arranged on the rotating shafts on two sides of the bearing, and the spacer bushes on one side close to the chain wheel are abutted with the chain wheel; the spacer bush close to one side of the encoder is abutted with the rotating piece of the encoder. The purpose is to ensure that in the using process, the leaping does not occur to influence the normal use.
Preferably, a key for limiting the rotation of the chain wheel along the circumferential direction of the rotating shaft is arranged between the rotating shaft and the chain wheel. The limiting structure is convenient to ensure that the chain wheel and the rotating shaft do not rotate relatively.
Has the advantages that: compared with the prior art, the advantage of this patent lies in:
1. the position information can be fed back in real time, and a plurality of detection switches are not required to be arranged under the condition that a plurality of positions are required to be controlled;
2. the problem that the position fed back by the encoder in the traditional mode is wrong when wheels of the trolley slip on the I-shaped steel is solved; when the wheels of the trolley slip, the trolley body still moves, and the chain wheel is meshed with the chain, so that the chain wheel still drives the encoder to rotate, and the real moving distance of the trolley body is fed back.
