The motor drives the traction wheel to rotate to drive the traction rope, dragging the car and the counterweight to move relative to each other, so as to achieve vertical movement of the car. There is wear between the traction rope and the rope groove, and wear detection is required.

[0048] The traction machine is a device that transmits traction power for the elevator. The traction rope of the traction machine is wound around the traction wheel of the traction machine. One end of the traction rope is connected to the car, and the other end is connected to the counterweight device. The gravity of the car and the counterweight device causes the traction rope to be pressed tightly in the rope groove of the traction wheel to generate friction and transmit power. There is wear between the traction rope and the rope groove, and wear detection is required.

[0049] Figure 1 It is a principle cross-sectional view of detecting wear of a traction rope in the background technology.

Then, a feeler gauge is placed, and the gap distance between the top end of each traction rope 43 and the bottom end of the ruler 5 is measured by the feeler gauge to detect whether there is wear on the traction rope 43 and / or the rope groove 421. However, in the case where the top space of the installation position of the traction machine 4 is limited, there is not enough space to place the feeler gauge, and the measurement data of the feeler gauge is not easy to observe, which is not convenient for wear detection.

[0051] In view of the deficiencies of the above-mentioned technology, the utility model provides a detection device for a traction machine 4 of an elevator, a traction machine 4 and an elevator.

[0052] Figure 2 It is a three-dimensional schematic diagram of a traction machine according to an embodiment of the utility model. Figure 3 yes Figure 2 Enlarged view of point A in the middle.

One end of the traction rope 43 is connected to the car, and the other end is connected to the counterweight device. The traction rope 43 is configured to transmit power through the friction force generated by the traction rope 43 pressing against the rope grooves 421 of the traction sheave 42 under the drive of the traction sheave 42.

[0054] The detection device is installed on the main body 41 and is adjacent to the fitting portion of the traction rope 43 and the traction wheel 42.

The detection device is easy to operate and is still easy to operate even when space is limited, thereby improving the convenience of detecting the wear of the traction rope 43 and / or the rope groove 421.

[0055] Figure 4 It is a three-dimensional schematic diagram of a detection member and a protruding portion according to an embodiment of the utility model.

[0056] According to the detection device for the traction machine 4 of the elevator provided by the utility model, as Figure 3 and Figure 4 As shown, the detection device includes a mounting mechanism 1, a detection member 2 and a protrusion 3. The mounting mechanism 1 is mounted on the housing of the traction machine 4, and the traction wheel 42 of the traction machine 4 rotates around an axis extending horizontally in a first direction to pull the traction rope 43. A plurality of detection members 2 extend in a second direction of the tangent of the traction wheel 42, and are slidably mounted on the mounting mechanism 1 in the second direction, and the middle portions of the detection members 2 are respectively roughly in contact with the outer edge surfaces of the fitting portions of the traction rope 43 that are wrapped around the traction wheel 42, or there is a small gap, so that the traction rope 43 has no friction with the middle portion of the detection member 2 during the rotation process.

[0057] like Figure 3 and Figure 4As shown, both ends of the side of each detection member 2 facing the traction rope 43 are provided with protrusions 3, that is, each detection member 2 is provided with a pair of protrusions 3. Multiple pairs of protrusions 3 are respectively arranged at both ends of the side of the detection member 2 facing the traction rope 43, and the thickness of each pair of protrusions 3 is greater than the gap between the middle part of the detection member 2 and the outer edge surface of the fitting part of the traction rope 43 wrapped around the traction wheel 42, and is constructed to be substantially in contact with the outer edge surface of the non-worn traction rope 43 or have a small gap, so that when a predetermined force is applied to the detection member 2, by measuring whether the detection member 2 slides in the second direction, whether the traction rope 43 and / or the rope groove 421 is worn, and by further measuring the sliding distance of the detection member 2, the wear degree of the traction rope 43 and / or the rope groove 421 is determined.

[0058] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the casing of the traction machine 4 is made of metal. The mounting mechanism 1 is mounted on the casing of the traction machine 4 by magnetic attraction. The mounting mechanism 1 can also be mounted on the casing of the traction machine 4 by bolts, and the detection device is easy to install.

[0059] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the mounting mechanism 1 includes a mounting assembly 11 and a positioning plate 12. The mounting assembly 11 is a plate-like structure, and the mounting assembly 11 is mounted on the housing of the traction machine 4 by means of magnets or bolts, and a first side of the mounting assembly 11 is in contact with the housing of the traction machine 4. The positioning plate 12 is mounted on a second side of the mounting assembly 11 opposite to the first side, and the positioning plate 12 extends in a first direction, and the side of the mounting assembly 11 and the positioning plate 12 facing the traction wheel 42 forms an arc that matches the traction wheel 42.

[0060] Figure 5 It is a cross-sectional view of a detection device according to an embodiment of the utility model. Figure 6 It is another cross-sectional view of the detection device according to an embodiment of the utility model.

[0061] In an exemplary embodiment, Figure 5 and Figure 6 As shown, a plurality of receiving grooves 121 extending in the second direction are provided on one side of the positioning plate 12 facing the traction wheel 42 . The plurality of receiving grooves 121 are spaced apart in the first direction and are respectively arranged opposite to the plurality of rope grooves 421 .

[0062] In an exemplary embodiment, Figure 5 and Figure 6As shown, a guide rib 122 extending in the second direction is provided on the inner wall of each receiving groove 121, and two guide ribs 122 are provided on the inner wall of each receiving groove 121. The two guide ribs 122 are respectively located in the middle of the two side walls of the receiving groove 121 to guide the detection member 2 to slide in the second direction, and the interval between the two guide ribs 122 allows the protrusion 3 to extend and slide in the second direction. The plurality of receiving grooves 121 are configured to respectively accommodate the detection member 2, and allow the traction rope 43 to partially extend into the receiving groove 121, respectively, so that the detection member 2 is roughly in contact with the outer edge surface of the portion of the traction rope 43 that is in contact with the traction wheel 42 (i.e., the portion that is wrapped around the traction wheel 42), or there is a small gap, so that the traction rope 43 has no friction with the middle portion of the detection member 2 during the rotation process.

[0063] In an alternative exemplary embodiment, a guide groove in the second direction is provided on the inner wall of each accommodating groove, and a guide block cooperating with the guide groove is provided on the detection member, and the guide block slides in the guide groove to guide the detection member to slide in the second direction.

[0064] According to the embodiment of the utility model, the mounting mechanism 1 is mounted on the housing of the traction machine 4, and is easy to disassemble and assemble. The multiple receiving grooves 121 of the mounting mechanism 1 are opposite to the rope grooves 421 on the traction wheel 42, so that the outer edge surface of the part where the traction rope 43 and the traction wheel 42 fit together partially extends into the bottom of the receiving groove 121. The guide rib 122 sets the detection member 2 in the receiving groove 121, so that the middle part of the detection member 2 is roughly in contact with the outer edge surface of the part where the traction rope 43 and the traction wheel 42 fit together, or there is a small gap, and guides the movement of the detection member 2 in the second direction.

[0065] In an exemplary embodiment, Figure 4 and Figure 5 As shown, each detection member 2 is provided with two protrusions 3, and the two protrusions 3 are respectively provided at the two ends of the side of the detection member 2 facing the traction rope 43. The operator can apply a predetermined force to the detection member 2 in both directions in the second direction, and detect whether the traction rope 43 and / or the rope groove 421 are worn by measuring whether the detection member 2 slides in the second direction, and determine the degree of wear of the traction rope 43 and / or the rope groove 421 by further measuring the sliding distance of the detection member 2.

[0066] In a replaceable exemplary embodiment, each detection member may also be provided with a protrusion, which is provided at an end portion of the side of the detection member facing the traction rope. The operator applies a predetermined force to the detection member unidirectionally in the second direction to move the protrusion in the second direction toward the direction close to the outer edge surface of the traction rope. The degree of wear of the traction rope and / or the rope groove can also be detected by measuring the sliding distance of the detection member in the second direction.

[0067] According to an embodiment of the utility model, in the initial state, the protrusion 3 is roughly in contact with the outer edge surface of the unworn traction rope 43 or there is a small gap, so that the traction rope 43 has no friction with the protrusion 3 during the rotation process. During detection, the operator applies a predetermined force to the detection member 2 in the second direction, so that the detection member 2 slides along the receiving groove 121 in the second direction. When the protrusion 3 abuts against the outer edge surface of the traction rope 43, and there is no sliding or the sliding distance is very small in the second direction, the wear of the traction rope 43 and / or the rope groove 421 is small, and there is no need to replace the traction rope 43 or the traction wheel 42. When the outer edge of the traction rope 43 faces the protrusion 3 without obstruction, so that the detection member 2 slides a large distance in the second direction, and the protrusion 3 extends into the receiving groove 121, it is detected that the traction rope 43 and / or the rope groove 421 are worn out.

[0068] In an exemplary embodiment, a marking line is provided on the side wall of the detection member, and the marking line is configured to indicate that the middle of the detection member is aligned with the middle of the positioning plate, so as to facilitate adjustment of the initial position of the detection member of the detection device.

[0069] In an exemplary embodiment, Figure 4 and Figure 5 As shown, a limit block 21 is provided at the first end of the detection member 2, and the limit block 21 and the detection member 2 are detachably connected by threaded connection or clamping, so that the detection member 2 is assembled into the receiving groove 121, and the limit block 21 is assembled with the detection member 2. The limit block 21 is located outside the port of the receiving groove 121 to prevent the first end of the detection member 2 from entering the receiving groove 121.

[0070] According to the embodiment of the utility model, in the initial state, the protrusion 3 is roughly in contact with the outer edge surface of the unworn traction rope 43 or there is a small gap, so that the traction rope 43 has no friction with the protrusion 3 during the rotation process. During the detection process, when the traction rope 43 and / or the rope groove 421 are worn out and fail, the gap between the traction rope 43 and the detection member 2 increases, and the detection member 2 slides along the receiving groove 121 in the second direction. The protrusion 3 and the end of the detection member 2 continue to extend into the receiving groove 121. When the limit block 21 is about to abut against the end of the receiving groove 121, it can be detected that the traction rope 43 and / or the rope groove 421 are worn out and fail, and need to be repaired and replaced. The operation is convenient and easy to operate even when the space is limited, which improves the convenience of detecting the wear of the traction rope 43 and / or the rope groove 421.

[0071] The limiting block 21 blocks the first end of the detection member 2 from entering the receiving groove 121 , thereby preventing the detection member 2 from being separated from the receiving groove 121 and being lost.

[0072] In an exemplary embodiment, Figure 4 and Figure 5As shown, the second end of the detection member 2 is provided with a handle 22, the handle 22 is located outside the port of the receiving groove 121, the first end of the handle 22 is perpendicular to the detection member 2, the first end of the handle 22 prevents the second end of the detection member 2 from entering the receiving groove 121, and the first end of the handle 22 prevents the detection member 2 from being separated from the receiving groove 121 and lost. The second end of the handle 22 extends in a direction away from the traction wheel 42, which is convenient for the operator to hold the handle 22 and apply external force to the detection member 2, further improving the convenience of operation.

[0073] In an exemplary embodiment, the detection device further includes a plurality of limit members (not shown in the figure), which are arranged on the positioning plate 12 and are configured to respectively prevent the detection member 2 from sliding in the second direction.

[0074] Specifically, each limiting member includes a limiting screw threaded through the positioning plate 12 and in contact with the side of the detection member 2 away from the traction rope 43 .

[0075] According to the embodiment of the utility model, when there is no detection, the operator rotates the limiter (limiting screw) so that the limiter is in close contact with the detection member 2, preventing the detection member 2 from sliding in the second direction, and preventing the detection member 2 from sliding under the action of vibration or unexpected external force and generating friction with the detection member 2, thereby affecting the normal use of the traction rope 43. When detection is required, the operator loosens the limiter and cancels the restraint of the limiter on the detection member 2 to apply a predetermined force to the detection member 2, and detects whether the traction rope 43 and / or the rope groove 421 are worn by measuring whether the detection member 2 slides in the second direction.

[0076] According to the elevator provided by the utility model, the traction machine 4 as described above is installed, and one end of the traction rope 43 of the traction machine 4 is connected to the car, and the other end is connected to the counterweight device. The gravity of the car and the counterweight device causes the traction rope 43 to be pressed tightly in the rope groove 421 of the traction sheave 42 of the traction machine 4 to generate friction and transmit power. The traction sheave 42 rotates to drive the traction rope 43, dragging the car and the counterweight to make relative motion, thereby realizing vertical movement of the car.

[0077] According to the detection device, traction machine 4 and elevator applicable to the elevator provided by the utility model, when in use, the operator applies a predetermined force to the detection member 2 in the second direction (the extension direction of the detection member) to measure the sliding distance of the detection member 2 in the second direction. When the traction rope 43 is not worn or the degree of wear is small, the outer edge surface of the traction rope 43 blocks the detection member 2 from sliding in the second direction, and the detection member 3 does not slide or the sliding distance is small; on the other hand, when the traction rope 43 and / or the rope groove 421 are worn greatly, the gap between the traction rope 43 and the detection member 2 and the protrusion 3 increases, and the outer edge of the traction rope 43 faces the protrusion 3 without blocking, so that the detection member 2 slides in the second direction, and the protrusion 3 extends into the receiving groove 121. When the limiter 21 contacts the port of the receiving groove 121, it is detected that the traction rope 43 and / or the rope groove 421 are worn to a large extent and fail. Replacement and maintenance are required, and it is still easy to operate in the case of limited space, which improves the convenience of detecting the wear of the traction rope 43 and / or the rope groove 421.

[0078] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific embodiments of the utility model and are not used to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
