Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
As shown in fig. 1 to 6, a device for measuring a traveling distance of a rail car in a greenhouse includes: the device comprises a trolley 11, a connecting support 1 and a rotating base 3, wherein the connecting support 1 is fixed on a trolley chassis 1101. The rotary base 3 is rotatably connected with the connecting support 1 through a rotating shaft 5, one end of the rotary base 3 is provided with a follower wheel 4, the rotary base 3 is fixedly connected with a bearing with a seat 6, the follower wheel 4 is connected with a main shaft 401, the main shaft 401 penetrates through the bearing with a seat 6 to be connected with a coupler 7, and the coupler 7 is connected with an encoder 8. A limiting plate 10 is fixedly arranged on the connecting support 1, the other end of the rotating base 3 is connected to the limiting plate 10 through a spring 9, and a proximity switch 2 is arranged on the connecting support 1. The trolley chassis 1101 is further provided with wheels 12, wherein the wheels 12 comprise an outer end landing section 1201, a middle arc groove section 1202 and an inner end connecting section 1203, the wheel diameter of the outer end landing section 1201 is larger than the wheel diameter of the follow-up wheel 4, and the wheel diameter of the groove bottom of the middle arc groove section 1202 is smaller than the wheel diameter of the follow-up wheel 4.
The wheel 12 structure of the chassis of the trolley 11 mentioned in the present invention is only a scheme, and the distribution positions of the landing section 1201, the arc groove section 1202 and the connecting section 1203 mentioned in the above technical scheme at the wheel 12 can be adjusted according to the actual situation of the user. For example, the vehicle chassis 1101 is further provided with a wheel 12, wherein the wheel 12 comprises an outer end circular arc groove section 1202, a middle landing section 1201 and an inner end connecting section 1203, the diameter of the middle landing section 1201 is larger than that of the follower wheel 4, and the diameter of the groove bottom of the outer end circular arc groove section 1202 is smaller than that of the follower wheel 4. The purpose is that when the trolley runs on the track 13, the track 13 can be clamped in the arc groove 1202, and the structural characteristics of the wheel 12 can be adjusted according to the width of the actual track 13. The wheels 12 are integrally formed, and different tracks 13 only need to be formed by selecting different wheels 12. The track 13 is an elongated circular tube, and the size of the track 13 meets the requirement of being clamped in the arc-shaped groove section 1202.
The specific working principle is as follows: the whole distance measuring device is fixedly arranged on a trolley chassis 1101 of a running trolley 11 through a connecting frame 1, when the trolley 11 runs on a horizontal ground, one end of a follow-up wheel 4 of a rotating base 3 moves downwards around a rotating shaft 5 under the action of self gravity of the follow-up wheel 4 and the tension of a spring 9, and the result is shown in the figure II. When the tail end of the rotating base 3 touches the limiting plate 10, the rotating base 3 stops floating downwards, at the moment, the proximity switch 2 cannot detect the rotating base 3 and feed back a signal to the control system, the system can judge that the trolley 11 does not run on the track 13 at the moment, the encoder 8 stops counting, even if the foreign matter on the ground causes the follow-up wheel 4 to rotate at the moment, the distance measuring device cannot measure and record the running distance of the trolley. The adjusting limit plate 10 can limit the up-down movement distance of the rotating base 3, and in the actual use process, the position of the limit plate 10 is fixed only by meeting the requirement of ensuring that the follower wheel 4 does not contact the ground. When the trolley 11 runs on the track 13, the track 13 is clamped in the arc groove section 1202 and is in contact with the follower wheel 4, one end of the follower wheel 4 of the rotating base 3 falls on the track 13, the proximity switch 2 detects a signal and sends a signal to the control system to display that the trolley 11 is on the track 13, as shown in the figure I; because the bearing effect of track 13 and the effect of spring 9 pulling force down, trailing wheel 4 tightly laminates on track 13 surface, and trailing wheel 4 rotates on track 13 surface along with dolly 11 when dolly 11 traveles to drive encoder 8 through shaft coupling 7 and rotate, through the count feedback of encoder 8, can accurate measurement dolly 11 actual working distance on track 13. Because the device is totally independent of dolly wheel 12, the wheel 12 skids and can not cause any influence to it, and the follow-up wheel 4 surface of count adopts polyurethane material, has increased the frictional force with between track 13 when guaranteeing certain hardness, has avoided the inaccurate phenomenon of range finding that causes because of the count follow-up gyro wheel phenomenon of skidding itself. When the trolley 11 runs to the ground from the track 13, one end of the follow-up wheel 4 of the rotating base 3 rotates downwards around the rotating shaft 5, the proximity switch 2 cannot detect a signal, and the measuring device stops the distance measuring function.
To sum up, the utility model discloses reach anticipated purpose.
