Technical Field

The present invention relates to the field of sensor devices, and more particularly to wear assemblies and sensing assemblies.

Background

Elevators are used to transport passengers to a destination location primarily by raising and lowering a car in a hoistway. The lift process of the car in the hoistway depends on the detection matching relation between a grating ruler arranged in the hoistway and a sensor arranged on the car. The sensor reads the coded information on the grating ruler, so as to assist in controlling the car to stop at a target floor. In order to ensure that the sensor can reliably read the coded information on the grating ruler, the relative position of the grating ruler and the sensor needs to be in a stable state, and excessive deviation cannot occur. Therefore, a wear-resistant part is arranged on the sensor at a position corresponding to the grid ruler, and when the grid ruler deviates, the wear-resistant part can be firstly contacted with the wear-resistant part, and the grid ruler is limited at a relatively fixed position by the wear-resistant part.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

In one embodiment, a sensing assembly 10 is provided, the sensing assembly 10 being positionable on a lift for controlling the stop of the lift at a target location. Specifically, as shown in fig. 1 and 2, the sensing assembly 10 includes a sensor 20 and a wear assembly 30.

Further, in one embodiment, as shown in fig. 1 and 2, the sensor 20 includes a sensor body 21, and the sensor body 21 is provided with a mounting groove 211 for passing the grating 40. The mounting groove 211 penetrates the top and bottom surfaces of the sensor body 21, and the wear-resistant member 30 is disposed in the mounting groove 211. The grid ruler 40 is limited in a target range by the wear-resistant component 30, so that the sensor body 21 can acquire coded information on the grid ruler 40, and the control process is completed. The sensor body 21 is disposed on a car of the elevator, and the grating 40 is disposed in a hoistway of the elevator and is disposed in a longitudinal direction. In the process of lifting the car, the grid ruler 40 and the sensor body 21 slide relatively.

Further specifically, as shown in fig. 3 and 6, in one embodiment, the wear assembly 30 includes a wear member 31 and a resilient abutment member 32. The wear member 31 is provided on the sensor body 21 to define the scale 40 within a target range. The wear part 31 can be pressed against the sensor body 21. Specifically, the wear-resistant member 31 may be disposed in the mounting main groove 211, and the wear-resistant member 31 abuts against a side wall of the mounting main groove 211. The elastic abutting member 32 abuts between the wear-resistant member 31 and the sensor body 21, and is used for providing a friction force for preventing relative sliding between the wear-resistant member 31 and the sensor body 21 in the longitudinal direction. In the normal use process, the phase position between the wear-resistant piece 31 and the sensor body 21 in the longitudinal direction is stable, the grid ruler 40 is limited in the target range, and the sensor body 21 can reliably detect the coding information on the grid ruler 40.

Furthermore, the wear-resistant member 31 is pressed against the sensor body 21 by the elastic abutting member 32. At the beginning of use, the grid 40 is limited to the target range. If the grid rule 40 is displaced during use, friction occurs between the grid rule 40 and the wear-resistant part 31. After a period of use, if the wear-resistant member 31 is worn seriously, based on that the wear-resistant member 31 is pressed against the sensor body 21 by the elastic abutting member 32, the friction force caused by the elastic force of the elastic abutting member 32 can be overcome by an external force, so that the wear-resistant member 31 and the sensor body 21 are displaced relatively in the longitudinal direction, and the elastic abutting member 32 is pressed and compressed transversely, so that the wear-resistant member 31 is detached from the sensor body 21 and replaced. The grid ruler 40 is ensured to be always limited in the target range, so that the detection reliability is always kept. Moreover, it is based on the fact that the wear-resistant member 31 is pressed against the sensor body 21 by the elastic force of the elastic abutment member 32. Therefore, when a foreign object 50 is caught between the ruler 40 and the wear-resistant member 31, as shown in fig. 4, if the clamping force of the foreign object 50 reaches a certain value, the wear-resistant member 31 is pulled down from the sensor body 21 along with the ruler 40, so as to be separated from the sensor body 21, thereby avoiding the dead-lock of the ruler 40.

Further, in an embodiment, as shown in fig. 4, a recess 212 may be further provided on the sensor body 21 at a position for contacting with the elastic abutting member 32. Or the wear-resisting piece 31 is provided with a recess at the position contacting with the elastic abutting piece 32. As shown in fig. 3, the elastic abutting member 32 can press against the recess 212, so that the relative position between the wear assembly 30 and the sensor body 21 is fixed. The grid ruler 40 is limited in the target range of the sensor body 21, and the reliability of detection is guaranteed. After a period of use, the resilient force of the resilient abutment member 32 can be overcome by an applied force, thereby removing and replacing the wear assembly 30 from the sensor 20, ensuring a consistent and reliable test result. Moreover, the sensor 20 can be used continuously only by replacing the wear-resistant component 30, and the replacement cost is low. As shown in fig. 4, if a foreign object 50 is jammed between the ruler 40 and the wear-resistant member 31, the wear-resistant member 31 moves together with the ruler 40 and is separated from the sensor body 21, so that the sensor body 21 is not damaged, and the ruler 40 is not jammed.

Alternatively, the sensor body 21 may not be provided with the recess 212, and the elastic abutting member 32 is pressed against the sensor body 21 completely by its own elastic force.

Further, in an embodiment, a side surface of the sensor body 21 for abutting against the elastic abutting member 32 is a limiting surface, a side surface of the wear-resistant member 31 opposite to the limiting surface is a first side surface 311, the elastic abutting member 32 is disposed on the wear-resistant member 31, and the elastic abutting member 32 protrudes from the first side surface 311 and can abut against the sensor body 21. When the wear-resistant member 31 is mounted in the mounting groove 211 of the sensor body 21, the elastic abutting member 32 abuts against the sensor body 21, so that the relative position between the wear-resistant member 31 and the sensor body 21 is fixed. When the wear-resistant member 31 and the sensor body 21 are displaced relatively, the elastic abutting member 32 can be pressed toward the first side 311.

It should be noted that, in the above solution, the elastic abutting piece 32 is disposed on the wear-resistant piece 31, and when the wear-resistant assembly 30 is assembled with the sensor body 21, the elastic abutting piece 32 abuts against the sensor body 21. Alternatively, the elastic abutting piece 32 can be arranged on the sensor body 21, and when the wear assembly 30 is assembled with the sensor body 21, the elastic abutting piece 32 abuts against the wear piece 31.

Further, in an embodiment, as shown in fig. 3 to 7, an end surface of the elastic abutting member 32 for abutting against the sensor body 21 is an abutting surface 321, and the abutting surface 321 is an arc-shaped surface protruding outward. Therefore, when the wear-resistant component 30 needs to be replaced, the replacement is more convenient under the guiding action of the arc-shaped surface. In particular, the extension direction of the arc-shaped surface is consistent with the sliding direction of the wear-resistant component 30 relative to the sensor body 21 when the wear-resistant component 30 is replaced, so that the wear-resistant component 30 can be pushed into or out of the mounting groove 211 of the sensor body 21 conveniently.

For example, in the embodiment shown in fig. 1 to 7, if the arrangement direction of the grating 40 in the hoistway is defined as the longitudinal direction, when the wear-resistant assembly 30 is replaced, the wear-resistant member 31 and the sensor body 21 are moved relative to each other in the longitudinal direction, so that the wear-resistant member 31 is separated from the sensor body 21. As shown in fig. 3 to 7, the extension direction of the arc-shaped surface is also longitudinal, which can provide effective guiding function for the replacement process and improve the convenience of replacement.

Specifically, the force required to be applied when replacing the wear assembly 30 is related to the elastic coefficient k of the elastic abutting member 32, the friction coefficient μ between the elastic abutting member 32 and the sensor body 21, and the depth d of the elastic abutting member 32 inserted into the recess 212 when the recess 212 is provided on the sensor body 21. For example, in one embodiment, if the elastic coefficient k is 100N/mm, the friction coefficient μ is 0.5, and the depth d is 4mm, the required applied force F is k × d × μ is 200N. Maintenance personnel need to apply a force of 200N in the longitudinal direction to the wear assembly 30 to replace the wear assembly 30. Moreover, when the foreign matter 50 is caught between the ruler 40 and the wear-resistant part 31, and the clamping force between the ruler 40 and the wear-resistant part 31 is greater than 200N, the wear-resistant component 30 will move along with the ruler 40 and separate from the sensor body 21.

Further, in an embodiment, as shown in fig. 3 to 5, the elastic abutting member 32 includes an elastic member 322 and an abutting block 323, one end of the elastic member 322 is connected to or abutted against the wear member 31, and the other end of the elastic member 322 is connected to or abutted against the abutting block 323, for abutting the abutting block 323 in a direction away from the first side surface 311.

When the wear-resistant assembly 30 is assembled to the sensor body 21, the abutting block 323 is pressed against the sensor body 21 by the elastic member 322, so that the relative position between the wear-resistant assembly 30 and the sensor body 21 is stabilized.

In particular, the elastic member 322 may be a compression spring. The elastic coefficient of the elastic abutting member 32 is the elastic coefficient of the elastic member 322.

Further, in one embodiment, as shown in fig. 3 to 5, the first side 311 of the wear-resistant member 31 is provided with a mounting groove 3111, the elastic member 322 is disposed in the mounting groove 3111, and the abutting block 323 protrudes from the first side 311. The mounting groove 3111 may serve as a receiving groove when the abutting block 323 is pressed. When the wear assembly 30 is replaced, as shown in fig. 4 and 5, the abutting block 323 is pressed by the sensor body 21 to recede into the mounting groove 3111. When the wear-resistant component 30 and the sensor body 21 are mounted in place, the abutting block 323 protrudes from the first side 311 under the action of the elastic member 322 and abuts against the sensor body 21.

It should be noted that, here, the abutting block 323 protrudes from the first side surface 311 means that when the abutting block 323 is only acted by the elastic member 322, the abutting block 323 can protrude from the first side surface 311, so that when the wear-resistant assembly 30 is mounted on the sensor body 21, the abutting block 323 can be pressed against the sensor body 21. If the recess 212 is not formed in the sensor body 21 and the surface of the sensor body 21 opposite to the first side surface 311 is a plane, when the wear-resistant component 30 is mounted on the sensor body 21, the abutting block 323 will be pressed by the sensor body 21 and be completely located in the mounting groove 3111. If the sensor body 21 is provided with a recess 212, as shown in fig. 3, the abutting block 323 will abut against the recess 212. Also, the abutment block 323 may be partially located in the recess 212 and partially located in the mounting groove 3111.

Specifically, as shown in fig. 3 to 5, the elastic member 322 is disposed on the bottom wall of the mounting groove 3111.

Further, as shown in fig. 4 and 5, in an embodiment, a limiting member 312 is disposed on a sidewall of the mounting groove 3111. The abutting block 323 comprises a limiting portion 3231 and an abutting portion 3232, which are connected to each other, the limiting portion 3231 is limited by the limiting member 312 on a side away from the first side surface 311, the abutting portion 3232 protrudes from the first side surface 311, and the limiting member 312 surrounds the abutting portion 3232.

The abutting portion 3232 protrudes from the first side 311 and then abuts against the recess 212 of the sensor body 21, and the position-limiting member 312 surrounding the abutting portion 3232 can provide a supporting force for the abutting block 323 in the longitudinal direction, so that the abutting block 323 does not rely on the elastic member 322 to provide a supporting force in the longitudinal direction. The abutting portion 3232 and the sensor body 21 mutually provide a force in the longitudinal direction based on a friction effect, so that the wear-resistant member 31 can be fixed relative to the sensor body 21 in the longitudinal direction.

Furthermore, the retaining member 312 surrounds the abutting portion 3232, so that when the wear assembly 30 is longitudinally moved, the abutting block 323 can only be retracted into the mounting groove 3111, and does not swing up and down at the angle shown in fig. 4 and 5. When the wear-resistant assembly 30 is not assembled in the sensor 20, the abutting block 323 moves away from the mounting groove 3111 under the action of the elastic element 322, and the limiting element 312 limits the limiting portion 3231 on the limiting element 312 toward one side of the bottom wall of the mounting groove 3111.

Further specifically, as shown in fig. 3 to 5, in an embodiment, the limiting member 312 includes an annular sheet structure disposed at an opening of the mounting groove 3111. The limiting member 312 is parallel to the first side surface 311, and an end surface of the abutting portion 3232 protruding from the limiting member 312 is a spherical surface.

The annular plate-like structure surrounds the spherical surface, so that the abutting block 323 can move only in the telescopic direction of the elastic member 322. And the guide effect of the spherical surface makes the moving process of the abutting block 323 more stable and smooth when being extruded.

Further, in another embodiment, as shown in fig. 6 and 7, the first side 311 of the wear-resistant member 31 is provided with an abdicating groove 3112, the elastic abutting member 32 is disposed at an opening of the abdicating groove 3112, and the elastic abutting member 32 is an elastic sheet 324. The outer edge of the elastic sheet 324 is connected with the wear-resistant member 31, and the middle portion of the elastic sheet 324 is bent and protruded from the first side surface 311 in a direction away from the bottom wall of the receding groove 3112.

As shown in fig. 6, when the wear-resistant assembly 30 is assembled to the sensor body 21, the elastic piece 324 protrudes and abuts against the sensor body 21 based on the elastic deformation force of the elastic piece. When the recess 212 is formed on the sensor body 21, the elastic piece 324 is tightly pressed against the recess 212. The outer edge of the elastic sheet 324 is connected with the wear-resistant part 31, and the relative position of the elastic sheet 324 at the opening of the receding groove 3112 is stable. Moreover, the opening of the receding groove 3112 is provided with the elastic sheet 324, which has the advantages of simple structure, less material types, low cost and long service life.

Further, in one embodiment, the elastic piece 324 is integrally connected with the wear-resistant member 31. The elastic sheet 324 is firmly connected to the wear-resistant member 31, and does not shake left and right. When the sensor body 21 is replaced, the wear-resistant component 30 is pushed, and the elastic sheet 324 can be stably pushed into the receding groove 3112, so that the wear-resistant component 30 can be separated from the sensor body 21.

Further, as shown in fig. 1 and 2, in one embodiment, the surface of the wear-resistant member 31 opposite to the ruler 40 is a limiting side 313, the limiting side 313 is provided with positioning grooves 3131, the distance between the side walls of the positioning grooves 3131 is slightly larger than the thickness of the ruler 40, and the edge of the ruler 40 can be located in the positioning groove 3131.

When the elevator is assembled, the wear-resistant assembly 30 is assembled on the sensor body 21 to form the sensing assembly 10, the sensing assembly 10 is arranged on a car, the grating 40 penetrates through the mounting main groove 211 on the sensor body 21, and the edge of the grating 40 is positioned in the positioning groove 3131.

Further, as shown in fig. 1 and 2, in the sensor assembly 10, two wear assemblies 30 are disposed in the mounting groove 211, two wear members 31 are disposed opposite to each other, the positioning groove 3131 is disposed on each of the limiting side surfaces 313 of the two wear members 31, and both edges of the grid 40 in the longitudinal direction are disposed in the positioning grooves 3131, so that the grid 40 is positioned between both sides.

Further, as shown in fig. 1 and 2, in one embodiment, the positioning groove 3131 penetrates through an upper surface and a lower surface of the wear member 31, where the upper surface and the lower surface of the wear member refer to the wear member 31 being disposed in the mounting groove 211 and mounted on the car together with the sensor body 21, the positioning groove 3131 being disposed in the longitudinal direction when the wear member 31 is disposed in the mounting groove 211, and the top surface of the wear member 31 being the upper surface and the bottom surface of the wear member 31 being the lower surface. The upper and/or lower surface of the wear part 31 is provided with a replacement logo coating 33. The replacement mark coating 33 is disposed on the positioning groove 3131 on a side away from the stopper side 313, and the replacement mark coating 33 surrounds the positioning groove 3131.

The edge of the ruler 40 is located in the positioning groove 3131, but during use, if the ruler 40 is offset from the sensing assembly 10, the ruler 40 will rub against the side wall or the bottom wall of the positioning groove 3131. When the wear part 31 is worn to the limit, the ruler bar 40 will come into contact with the replacement identification coating 33.
