Description

Technical Field

[0001] The present application relates to the technical field of drum rope groove measuring devices, and in particular to an auxiliary device for detecting drum rope grooves. Background Art

[0002] Drums are generally required in mechanical structures such as winches. As Figure 1 shown, a drum rope groove 100 is provided on the outer peripheral surface of the drum for winding a flexible rope.

[0003] For the detection of the distance between two drum rope grooves 100, it usually depends on the visual inspection of the operator. This method not only has low measurement accuracy, but also low efficiency and high subjectivity. At present, the solution in the related art is to use conventional detection tools such as calipers for manual measurement, or to use a simple test rod 200 for auxiliary detection.

[0004] However, in the method of measuring with calipers, the influence of human factors is large and the accuracy is low; while in the method of using a test rod for auxiliary measurement, as Figure 2 shown, there is a problem of instability when the test rod 200 is placed on the drum rope groove 100, which is likely to affect the measurement accuracy and increase the measurement difficulty; moreover, on the basis of using the test rod 200, if a tape measure is used for measurement, although the accuracy can be improved to a certain extent, however, as Figure 3 shown, there is no space for the end of the tape measure to penetrate between the test rod 200 and the end face of the drum, so the measurement of the end drum rope groove 100 cannot be carried out, and the measurement requirements cannot be met.

[0005] In the above related art, there are defects of low measurement accuracy between two drum rope grooves and difficulty in measuring the end rope grooves. Utility Model Content

[0006] In order to improve the problems of low measurement accuracy between two drum rope grooves and difficulty in measuring the end drum rope grooves, the present application provides an auxiliary device for detecting drum rope grooves.

[0007] The auxiliary device for detecting drum rope grooves provided by the present application adopts the following technical solutions:

[0008] An auxiliary device for detecting the rope grooves of a drum, which is used to measure the distance between two rope grooves of the drum. The auxiliary device for detecting the rope grooves of the drum includes: a support mechanism, which includes a first support block and a first guide rail. The end of the first guide rail is connected to the first support block, and the first support block is used to cooperate with one rope groove of the drum; a sliding mechanism, which includes a slider. The slider is slidably connected to the first guide rail, and the slider is used to cooperate with another rope groove of the drum; a scale mechanism, which includes a main scale and a sub-scale. One end of the main scale is connected to the first support block, and the length direction of the main scale is parallel to the length direction of the first guide rail. The sub-scale is connected to the slider, and the sub-scale is slidably matched with the main scale for measuring the distance between the slider and the first support block.

[0009] By adopting the above technical solution, the support mechanism is used to support the sliding mechanism and the scale mechanism. The end of the first guide rail is connected to the first support block, so that the first support block can be used to support the first guide rail. During use, the first support block is matched with one rope groove of the drum, and the slider on the first guide rail is slid so that the slider is matched with another rope groove of the drum. Since the slider is connected to the sub-scale, the sub-scale can be driven to slide on the main scale, so as to realize reading through the alignment and cooperation of the sub-scale and the main scale. The distance between the two rope grooves corresponding to the first support block and the slider can be obtained through the read value, thereby realizing the measurement of the distance between the two rope grooves of the drum; since the scale mechanism connected to the support mechanism is provided, the stability during measurement can be improved through the support mechanism, and the measurement accuracy can be improved; moreover, the first support block is arranged at the end of the first guide rail, which can facilitate the cooperation between the first support block and the rope groove at the end of the drum. The end of the main scale is connected to the first support block and does not need to extend between the first support block and the end face of the drum, so as to conveniently realize the measurement of the rope groove at the end of the drum and reduce the measurement difficulty.

[0010] Optionally, it further includes a first detection head and a second detection head. The first detection head is connected to the first support block, and the second detection head is connected to the slider. An arc surface is provided on the side of the first detection head away from the first support block and on the side of the second detection head away from the slider. The arc surface is used to cooperate with the surface of the rope groove of the drum.

[0011] By adopting the above technical solution, both the first detection head and the second detection head are provided with arc surfaces, which can facilitate the limit cooperation with the rope groove, increase the contact area with the rope groove, improve the stability during measurement, thereby helping to reduce the measurement error and improve the measurement accuracy.

[0012] Optionally, the side of the first detection head away from the second detection head is flush with the side of the first support block away from the slider.

[0013] By adopting the above technical solution, the first detection head will not protrude along the length extension direction of the first guide rail, avoiding the problem of being unable to measure the rope groove at the end of the drum.

[0014] Optionally, protruding blocks are provided on both the first detection head and the second detection head, and grooves are provided on both the first support block and the slider. The protruding blocks are slidably connected in the grooves, enabling the first detection head and the second detection head to move in a direction perpendicular to the length of the first guide rail.

[0015] By adopting the above technical solution, the first detection head can move relative to the first support block, and the second detection head can move relative to the slider, thus facilitating the adjustment of the positions of the first detection head and the second detection head, reducing the difficulty of alignment and cooperation with the rope groove of the drum; at the same time, the cooperation between the protruding blocks and the grooves can improve the stability of the first detection head and the second detection head, thereby ensuring sufficient measurement accuracy.

[0016] Optionally, the first detection head is detachably connected to the first support block, and the second detection head is detachably connected to the slider.

[0017] By adopting the above technical solution, the detachable connection method of the first detection head and the second detection head can facilitate replacement or maintenance when the first detection head and the second detection head are damaged, or for different specifications of the rope grooves of the drum, contributing to ensuring measurement accuracy, improving applicability, and reducing operation difficulty.

[0018] Optionally, the secondary scale includes a limit groove, the main scale is inserted into the limit groove, an opening is provided above the limit groove, the scale value of the main scale is exposed through the opening, and the height of the limit groove along the direction perpendicular to the length of the main scale is greater than the thickness of the main scale.

[0019] By adopting the above technical solution, the limit groove of the secondary scale can be used to achieve a sliding connection with the main scale, enabling the secondary scale to move linearly along the main scale to measure the distance between two rope grooves of the drum; and, with the opening provided in the limit groove, it is convenient to expose the scale value on the main scale, thus facilitating reading; the height of the limit groove being greater than the thickness of the main scale can reduce the wear of the scale value on the main scale due to the sliding of the secondary scale relative to the main scale, thereby extending the service life of the main scale.

[0020] Optionally, the upper end of the secondary scale is provided with an inclined surface, scale values are provided on the inclined surface, and the height of the first end of the inclined surface away from the axis extending in the length direction of the main scale is greater than the height of the second end of the inclined surface close to the axis extending in the length direction of the main scale.

[0021] By adopting the above technical solution, the scale values of the secondary scale are set on the inclined surface. On the basis that the height of the limit groove is greater than the thickness of the main scale and the upper end of the secondary scale is far from the surface of the main scale, the scale values on the secondary scale can be made close to the scale values of the main scale through the inclined surface, so that the alignment of the two scale values can be facilitated, which helps to reduce the reading difficulty and improve the measurement accuracy.

[0022] Optionally, the support mechanism includes a second guide rail, the end of the second guide rail is connected to the first support block, the second guide rail is spaced below the main scale, the first guide rail and the second guide rail are spaced apart, and the slider is slidably connected to the second guide rail; the sliding mechanism includes a locking member, the slider is provided with a locking hole, the locking member is screwed into the locking hole, and the end of the locking member can selectively abut against the second guide rail to relatively fix the slider and the second guide rail.

[0023] By adopting the above technical solution, the setting of the second guide rail can improve the guiding property of the slider. The first guide rail and the second guide rail are used to limit the slider, prevent the slider from rotating, and can reduce the contact between the secondary scale and the main scale perpendicular to the length direction of the first guide rail, thereby reducing the friction between the main scale and the secondary scale, improving the smoothness of the sliding of the secondary scale, and reducing the measurement difficulty; during measurement, after the positions of the first support block and the slider are determined, the slider can be fixed in position by the locking member pressing against the second guide rail, so that reading can be realized under stable conditions, which helps to improve the measurement accuracy.

[0024] Optionally, the support mechanism includes a second support block, the second support block is spaced from the first support block, both ends of the first guide rail are respectively connected to the first support block and the second support block, both ends of the second guide rail are respectively connected to the first support block and the second support block, and both ends of the main scale are respectively connected to the first support block and the second support block.

[0025] By adopting the above technical solution, the second support block can improve the stability of the first guide rail and the second guide rail, so that the movement of the slider and the secondary scale is more stable, which helps to improve the measurement accuracy.

[0026] Optionally, it further includes an electronic digital display component, the electronic digital display component is arranged on the scale mechanism, and the electronic digital display component is electrically connected to the scale mechanism.

[0027] By adopting the above technical solution, the electronic digital display component is used to display the measurement value of the scale mechanism, reduce the reading difficulty, and can obtain the measurement data intuitively and conveniently.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The support mechanism is used to support the sliding mechanism and the scale mechanism. The end of the first guide rail is connected to the first support block, enabling the first support block to support the first guide rail. During use, the first support block is engaged with a drum rope groove, and the slider on the first guide rail is slid so that the slider is engaged with another drum rope groove. Since the slider is connected to the secondary scale, it can drive the secondary scale to slide on the main scale, thereby enabling reading through the alignment and cooperation of the secondary scale and the main scale. The distance between the two drum rope grooves corresponding to the first support block and the slider can be obtained from the reading value, thus realizing the measurement of the distance between the two drum rope grooves. Due to the provision of the scale mechanism connected to the support mechanism, the stability during measurement can be improved through the support mechanism, enhancing the measurement accuracy. Moreover, the first support block is provided at the end of the first guide rail, facilitating the engagement of the first support block with the rope groove at the end of the drum. The end of the main scale is connected to the first support block and does not need to extend between the first support block and the end face of the drum, thereby enabling convenient measurement of the rope groove at the end of the drum and reducing the measurement difficulty.

[0030] 2. Both the first detection head and the second detection head are provided with arc-shaped surfaces, which facilitate the limit cooperation with the rope groove, increase the contact area with the rope groove, improve the stability during measurement, thus helping to reduce the measurement error and enhance the measurement accuracy.

Detailed implementation mode

[0040] The following is combined with the attached Figure 1 - attached Figure 6 The present application will be further described in detail. In this embodiment, unless otherwise clearly specified, "connection", "connection" and "fixation" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and the interaction between two components, etc., which can be understood according to specific situations.

[0041] In the present application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but in contact through other features therebetween. Moreover, in the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "right" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application. Without contrary description, the orientation terms such as "inside, outside" used in the present application refer to the outline of the corresponding component itself.

[0042] As Figure 1 and Figure 4 As shown, the embodiment of the present application discloses an auxiliary device for detecting a drum rope groove (hereinafter simply referred to as "device"). This device is applicable to equipment containing drums such as overhead cranes, elevators, and hoisting machinery, and is used in the application scenario of detecting the drum rope groove 100. The device includes a support mechanism 1, a sliding mechanism 2, and a scale mechanism 3, and is used to measure the distance between two drum rope grooves 100.

[0043] The support mechanism 1 can be placed on the reel and is used to support the sliding mechanism 2 and the scale mechanism 3. The support mechanism 1 includes a first support block 11 and a first guide rail 12. The end of the first guide rail 12 is connected to the first support block 11, enabling the first support block 11 to support the first guide rail 12. The first support block 11 is used to cooperate with a reel rope groove 100. The sliding mechanism 2 includes a slider 21, which is slidably connected to the first guide rail 12. The slider 21 is used to cooperate with another reel rope groove 100. The cooperation between the first guide rail 12 and the slider 21 enables the slider 21 to accurately move along the axial direction of the reel, ensuring that each reel rope groove 100 can be accurately detected. When in use, the support mechanism 1 is placed on the reel, and the length direction of the first guide rail 12 extends along the axis of the reel, enabling the first support block 11 to cooperate with a reel rope groove 100. Slide the slider 21 on the first guide rail 12 to align and cooperate the slider 21 with another reel rope groove 100.

[0044] As Figure 1 and Figure 4 shown, the scale mechanism 3 includes a main scale 31 and a sub-scale 32. One end of the main scale 31 is connected to the first support block 11, and the length direction of the main scale 31 is parallel to the length direction of the first guide rail 12. The sub-scale 32 is connected to the slider 21 and is slidably engaged with the main scale 31. The distance between the slider 21 and the first support block 11 is measured by the sub-scale 32 and the main scale 31. Since the slider 21 is connected to the sub-scale 32, the sliding of the slider 21 can drive the sub-scale 32 to slide on the main scale 31, so as to realize numerical reading and recording through the alignment and cooperation of the sub-scale 32 and the main scale 31. The distance between the two reel rope grooves 100 corresponding to the first support block 11 and the slider 21 can be obtained through the read numerical value, thereby realizing the measurement of the distance between the two reel rope grooves 100. Move the slider 21 along the axial direction of the reel and repeat the above steps until all the reel rope grooves 100 are detected, which helps to improve the measurement efficiency. By measuring the distance between two reel rope grooves 100, the pitch of the reel rope groove 100 can be calculated or obtained. The method of reading the scale after the main scale 31 and the sub-scale 32 are cooperated can refer to the reading method of a vernier caliper, which will not be described in detail here. Since the scale mechanism 3 connected to the support mechanism 1 is provided, the stability during measurement can be improved through the support mechanism 1, and the measurement accuracy can be improved. Moreover, the first support block 11 is arranged at the end of the first guide rail 12, which facilitates the cooperation between the first support block 11 and the rope groove at the end of the reel. The end of the main scale 31 is connected to the first support block 11 and does not need to extend between the first support block 11 and the end face of the reel, so as to conveniently realize the measurement of the rope groove at the end of the reel and reduce the measurement difficulty and the influence of human factors.

[0045] As Figure 4 、 Figure 5 and Figure 6As shown, optionally, the support mechanism 1 includes a second guide rail 13. The end of the second guide rail 13 is connected to the first support block 11. The second guide rail 13 is disposed at intervals below the main scale 31. The first guide rail 12 and the second guide rail 13 are arranged at intervals. The slider 21 is slidably connected to the second guide rail 13. The arrangement of the second guide rail 13 can improve the guiding property of the slider 21. The limiting effect on the slider 21 is realized through the first guide rail 12 and the second guide rail 13, preventing the slider 21 from rotating, and reducing the contact between the secondary scale 32 and the main scale 31 perpendicular to the length direction of the first guide rail 12, thereby reducing the friction between the main scale 31 and the secondary scale 32, improving the smoothness of the sliding of the secondary scale 32, and reducing the measurement difficulty. The sliding mechanism 2 includes a locking member 22. The slider 21 is provided with a locking hole. The locking member 22 is screwed into the locking hole. The end of the locking member 22 can selectively abut against the second guide rail 13 to relatively fix the slider 21 and the second guide rail 13. During measurement, after the relative positions of the first support block 11 and the slider 21 are determined, by using the locking member 22 to press against the second guide rail 13, the position of the slider 21 can be fixed, avoiding measurement errors caused by vibration or accidental touch, so that reading can be realized under stable conditions, which helps to improve the measurement accuracy. The locking member 22 can be a bolt, and the locking hole can be a threaded hole. The threaded hole communicates with the second guide rail 13. The bolt is screwed into the threaded hole so that the end of the bolt can abut against the second guide rail 13, thereby restricting the sliding of the slider 21 and improving the stability of the slider 21, facilitating accurate reading.

[0046] Optionally, the support mechanism 1 includes a second support block 14. The second support block 14 is arranged at intervals with the first support block 11. The two ends of the first guide rail 12 are respectively connected to the first support block 11 and the second support block 14. The two ends of the second guide rail 13 are respectively connected to the first support block 11 and the second support block 14. The two ends of the main scale 31 are respectively connected to the first support block 11 and the second support block 14. The second support block 14 can improve the stability of the first guide rail 12 and the second guide rail 13, so that the movement of the slider 21 and the secondary scale 32 is more stable, which helps to improve the measurement accuracy.

[0047] As Figure 1 、 Figure 4 and Figure 5As shown, optionally, the device further includes a first detection head 4 and a second detection head 5. The first detection head 4 is connected to the first support block 11, and the second detection head 5 is connected to the slider 21. An arc surface is provided on the side of the first detection head 4 away from the first support block 11 and on the side of the second detection head 5 away from the slider 21. The arc surface is used to cooperate with the surface of the drum rope groove 100. Both the first detection head 4 and the second detection head 5 are provided with arc surfaces, which can facilitate the limit cooperation with the drum rope groove 100, increase the contact area with the drum rope groove 100, improve the stability during measurement, thereby helping to reduce the measurement error and improve the measurement accuracy. The cross-sectional shapes of the first detection head 4 and the second detection head 5 are determined according to the cross-sectional shape of the drum rope groove 100, so that the first detection head 4 and the second detection head 5 can fit the drum rope groove 100, increase the contact area with the peripheral wall of the drum rope groove 100, and thus reduce the error; in this embodiment, the cross-sections of both the first detection head 4 and the second detection head 5 are semi-circular.

[0048] Optionally, the side of the first detection head 4 away from the second detection head 5 is flush with the side of the first support block 11 away from the slider 21, so that the first detection head 4 will not protrude along the length extension direction of the first guide rail 12, avoiding the problem of being unable to measure the rope groove at the end of the drum. The starting section of the scale value on the main scale 31 is matched with one end of the first detection head 4 close to the second detection head 5, and the starting section of the scale value on the secondary scale 32 is matched with one end of the second detection head 5 close to the first detection head 4, so as to measure the distance between the first detection head 4 and the second detection head 5, such as the minimum distance along the drum axis direction, through the cooperation between the main scale 31 and the secondary scale 32, and thus further obtain parameters such as the pitch.

[0049] Such as Figure 1 、 Figure 4 and Figure 5 As shown, optionally, the first detection head 4 is detachably connected to the first support block 11, and the second detection head 5 is detachably connected to the slider 21, such as by a bolt connection. The detachable connection method of the first detection head 4 and the second detection head 5 can facilitate replacement or maintenance when the first detection head 4 and the second detection head 5 are damaged or for drum rope grooves 100 of different specifications, which helps to ensure the measurement accuracy, improve the applicability, and reduce the operation difficulty.

[0050] Optionally, protruding blocks 6 are provided on both the first detection head 4 and the second detection head 5. Grooves are provided on both the first support block 11 and the slider 21. The protruding blocks 6 are slidably connected to the grooves, enabling the first detection head 4 and the second detection head 5 to move in a direction perpendicular to the length of the first guide rail 12. The first detection head 4 can move relative to the first support block 11, and the second detection head 5 can move relative to the slider 21, thereby facilitating the adjustment of the positions of the first detection head 4 and the second detection head 5 to reduce the difficulty of alignment and the risk of interference with the drum rope groove 100. At the same time, the cross-sectional shape of the protruding block 6 and the cross-sectional shape of the groove are set as required and cooperate with each other. The cooperation between the protruding block 6 and the groove can limit the relative movement along the drum axis direction, improving the stability of the first detection head 4 and the second detection head 5, and thus ensuring sufficient measurement accuracy.

[0051] As Figure 1 , Figure 4 and Figure 6 shown, optionally, the secondary scale 32 includes a limit groove 321, and the primary scale 31 is inserted into the limit groove 321. The limit groove 321 of the secondary scale 32 can be used to achieve a sliding connection with the primary scale 31, enabling the secondary scale 32 to move linearly along the primary scale 31 to measure the distance between two drum rope grooves 100. An opening is provided above the limit groove 321, and the scale value of the primary scale 31 is exposed through the opening, thus facilitating reading and reducing wear. The height of the limit groove 321 in a direction perpendicular to the length of the primary scale 31 is greater than the thickness of the primary scale 31, which can reduce the wear of the scale value on the primary scale 31 due to the sliding of the secondary scale 32 relative to the primary scale 31, thereby extending the service life of the primary scale 31.

[0052] As Figure 1 , Figure 4 and Figure 6As shown, optionally, the upper end of the secondary scale 32 is provided with an inclined surface 322, and scale values are provided on the inclined surface 322, such that the scale values on the inclined surface 322 are located above the scale values of the main scale 31. The height of the first end of the inclined surface 322 away from the axis extending in the length direction of the main scale 31 is greater than the height of the second end of the inclined surface 322 close to the axis extending in the length direction of the main scale 31. By setting the scale values of the secondary scale 32 on the inclined surface 322, that is, the height of the first end of the inclined surface 322 is greater than that of the second end, and the scale values of the secondary scale 32 are arranged close to the second end of the inclined surface 322, on the basis that the height of the limit slot 321 is greater than the thickness of the main scale 31 and the upper end of the secondary scale 32 is away from the surface of the main scale 31, the scale values on the secondary scale 32 can be made close to the scale values of the main scale 31 through the inclined surface 322. Thus, while improving the support strength, it is convenient to align the two scale values, which helps to reduce the reading difficulty and improve the measurement accuracy. In this embodiment, "above" and "below" refer to the positional relationship when the scale values of the main scale 31 face upward.

[0053] Optionally, the device further includes an electronic digital display component, which is arranged on the scale mechanism 3 and electrically connected to the scale mechanism 3. The electronic digital display component is used to display the measurement value of the scale mechanism 3, reducing the reading difficulty and enabling intuitive and convenient acquisition of measurement data. The operating principle of the electronic digital display component is similar to that of an electronic digital caliper. In view of the existing related technologies, the principle and structure thereof will not be described in detail herein. It can be understood that the device further includes necessary structures for functions such as connection, support, drive, positioning, limitation, and control, so that the device can operate normally; parameters such as the shape, size, material, and setting quantity of each part of the device can be determined according to needs as long as the corresponding functions can be achieved. The first support block 11 of the device can be close to the first end of the reel or the second end of the reel, and its setting direction and placement position are not limited as long as it is convenient for measurement.

[0054] The implementation principle of an auxiliary device for detecting the rope grooves of a drum in an embodiment of the present application is as follows: During use, the first support block 11 is fitted with one drum rope groove 100, and the slider 21 on the first guide rail 12 is slid to make the slider 21 fit with another drum rope groove 100. Since the slider 21 is connected to the secondary scale 32, it can drive the secondary scale 32 to slide on the primary scale 31, so as to achieve reading through the alignment and cooperation of the secondary scale 32 and the primary scale 31. The distance between the two drum rope grooves 100 corresponding to the first support block 11 and the slider 21 can be obtained through the reading value, thereby realizing the measurement of the distance between the two drum rope grooves 100; The scale mechanism 3 connected to the support mechanism 1 can improve the stability during measurement and the measurement accuracy through the support mechanism 1; Moreover, the first support block 11 is arranged at the end of the first guide rail 12, which can facilitate the cooperation between the first support block 11 and the drum rope groove 100 at the end of the drum. The end of the primary scale 31 is connected to the first support block 11 and does not need to extend between the first support block 11 and the end face of the drum, so as to conveniently realize the measurement of the rope groove at the end of the drum and reduce the measurement difficulty.

[0055] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
