Description
Technical Field
The utility model relates to a nut wear monitoring technology field, in particular to screw-nut drive mechanism with bear nut wearing and tearing and detect function.
Background
In the screw rod nut transmission mechanism, most of the time for monitoring the abrasion loss of the nut threads is inspected in a visual inspection mode, and the visual inspection mode has low automation degree; and relies heavily on the experience and responsibility of the operator. Many lifting devices are subject to accidents due to lack of a nut wear monitoring link.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a screw-nut drive mechanism with bear nut wearing and tearing and detect function to the wearing and tearing volume degree of automation who solves traditional range estimation monitoring nut is low, excessively relies on operating personnel's experience and the easy problem that meets accident of responsibility heart.
In order to solve the technical problem, the utility model provides a screw nut transmission mechanism with a bearing nut wear detection function, which comprises a bearing nut, a safety nut and a screw rod, wherein the bearing nut and the safety nut both pass through the screw rod and are in threaded connection with the screw rod;
a nut seat is arranged at one end of the bearing nut, and the bearing nut is fixedly connected with the nut seat through a bolt;
the side wall of the bearing nut is fixedly connected with a proximity switch;
the switch induction plate is fixedly connected to the side wall of the safety nut.
Optionally, the bearing nut and the safety nut are arranged oppositely, and a safety distance is reserved between the bearing nut and the safety nut.
Optionally, the proximity switch is a photoelectric sensor.
Optionally, the proximity switch and the switch induction plate are located on the same vertical plane.
Optionally, the bearing nut and the safety nut are connected through a guide pillar, and under the rotation action of the screw rod, the bearing nut and the safety nut slide back and forth along the screw rod.
The utility model provides a lead screw nut transmission mechanism with bearing nut wear detection function, which comprises a bearing nut, a safety nut and a lead screw, wherein the bearing nut and the safety nut both pass through the lead screw and are in threaded connection with the lead screw; a nut seat is arranged at one end of the bearing nut, and the bearing nut is fixedly connected with the nut seat through a bolt; the side wall of the bearing nut is fixedly connected with a proximity switch; the switch induction plate is fixedly connected to the side wall of the safety nut. This screw-nut drive mechanism with bear nut wearing and tearing and detect function compares with traditional range estimation monitoring nut wearing and tearing volume, and degree of automation is high, proximity switch can realize real time monitoring to send the warning, greatly reduced the probability that the accident took place.
Drawings
Fig. 1 is a schematic front structural view of a screw nut transmission mechanism with a bearing nut wear detection function provided by the present invention;
fig. 2 is a schematic side view of a lead screw nut transmission mechanism with a function of detecting wear of a bearing nut provided by the present invention.
Detailed Description
The following describes in detail a lead screw nut transmission mechanism with a wear detection function of a load nut according to the present invention with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
Example one
The utility model provides a screw nut transmission mechanism with bearing nut wear detection function, the structure of which is shown in figure 1, and the transmission mechanism comprises a bearing nut 1, a safety nut 2 and a screw rod 3, wherein the bearing nut 1 and the safety nut 2 both pass through the screw rod 3 and are in threaded connection with the screw rod 3; a nut seat 4 is arranged at one end of the bearing nut 1, and the bearing nut 1 is fixedly connected with the nut seat 4 through a bolt 5; the side wall of the bearing nut 1 is fixedly connected with a proximity switch 6; the side wall of the safety nut 2 is fixedly connected with a switch induction plate 7.
Specifically, the bearing nut 1 and the safety nut 2 are arranged oppositely, and a safety distance is reserved between the bearing nut 1 and the safety nut 2, so that when the thread of the bearing nut 1 is worn, the safety distance is reduced; the proximity switch 6 is a photoelectric sensor; the proximity switch 6 and the switch induction plate 7 are positioned on the same vertical plane; when the distance between the proximity switch 6 and the switch induction plate 7 is smaller than the minimum safe distance, the proximity switch 6 sends an alarm signal, so that the real-time monitoring of the bearing nut 1 is realized, and the probability of accidents is greatly reduced.
Specifically, as shown in fig. 2, the bearing nut 1 and the safety nut 2 are connected by a guide post 8, and under the rotation action of the screw rod 3, the bearing nut 1 and the safety nut 2 slide back and forth along the screw rod 3.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
