Description

Technical Field

[0001] This disclosure relates to the field of elevator equipment technology, and more specifically to a traction belt detection device. Background Technology

[0002] In the elevator industry, a large number of steel traction belts are used for traction. These traction belts are generally composed of multiple parallel steel wire rope cores inside and a wear-resistant layer tightly wrapped around the outside of these cores. Compared to traction steel wire ropes, the steel cores inside traction belts are more difficult to inspect because they cannot be directly observed with the naked eye.

[0003] Currently, when inspecting the steel core inside the traction belt, it is generally necessary to set up the inspection device on the traction belt and connect the various components of the inspection device through wiring. This results in messy inspection wiring, complicated wiring, and the inspection device has a complex structure and high cost. Summary of the Invention

[0037] Embodiments of this disclosure provide a traction belt detection device for detecting at least two steel cores within a traction belt 1. The at least two steel cores include a first steel core 11 and a second steel core 12. The traction belt detection device includes: a detection device 2 having a current output terminal and a current input terminal; a first detection component 3 disposed at a first position on the traction belt 1 for electrically connecting the first steel core 11 and the second steel core 12; and a second detection component 4 disposed at a second position on the traction belt 1 for electrically connecting the first steel core 11 to the current output terminal of the detection device 2 and electrically connecting the second steel core 12 to the current input terminal of the detection device 2. The second detection component 4 includes: a second fixed base 41; a second detection block 42 detachably connected to the second fixed base 41, forming a second receiving cavity 43 between the second detection block 42 and the second fixed base 41; an input cutting head 44 disposed on the second detection block 42 and electrically connected to the current output terminal of the detection device 2, wherein the input cutting head 44 is electrically connected to the first steel core 11 when the traction belt 1 passes through the second receiving cavity 43; and a return cutting head 45 disposed on the second detection block 42 and electrically connected to the current input terminal of the detection device 2, wherein the input cutting head 44 is electrically connected to the second steel core 12 when the traction belt 1 passes through the second receiving cavity 43. Through the above structural design, a first detection component 3 is set at the first position of the traction belt 1, and a second detection component 4 is set at the second position of the traction belt 1. The first detection component 3 is used to electrically connect each steel core at the first position, and the second detection component 4 is used to connect and disconnect current, so that the steel cores between the first position and the second position are connected to form a current path. Then, the fault of the steel cores between the first position and the second position can be determined by detecting the continuity of the current.

[0038] It should be noted that the traction belt detection device of this embodiment can detect a traction belt 1 comprising at least two steel cores, the two steel cores being represented by a first steel core 11 and a second steel core 12, respectively. It should be understood that the first steel core 11 and the second steel core 12 are any two steel cores located inside the traction belt 1, and the first steel core 11 and the second steel core 12 may be adjacent or not adjacent.

[0039] Figure 1 The diagram illustrates an application scenario of the traction belt detection device according to an embodiment of the present disclosure.

[0040] like Figure 1 As shown, the traction belt detection device according to this embodiment may include a detection device 2, a first detection component 3, and a second detection component 4. The detection device 2 has a current output terminal and a current input terminal. The detection device 2 outputs current to the second detection component 4 through the current output terminal, and receives current from the second detection component 4 through the current input terminal. When detecting the traction belt 1, the first detection component 3 and the second detection component 4 are respectively installed at both ends of the traction belt 1 to be tested, so that faults such as breakage of the steel core between the first detection component 3 and the second detection component 4 can be detected. It should be noted that, for ease of description, in this embodiment, the first position and the second position are respectively used to represent the two ends of the traction belt 1 to be tested, that is, the first position and the second position are located at different positions along the length of the traction belt 1. It should be understood that the first position and the second position are merely exemplary and are not intended to limit the scope of the present invention. It should also be noted that the detection device 2 only needs to meet the conditions of being able to provide current and being able to detect the current continuity. In this embodiment, the specific structure of the detection device 2 is not limited. For example, the detection device 2 may include a power supply, an ammeter, or a multimeter.

[0041] Figure 2 A perspective view of the second detection component 4 according to an embodiment of the present disclosure is shown schematically. Figure 3 A cross-sectional view of the second detection component 4 according to an embodiment of the present disclosure is schematically shown; and Figure 4 A top view of the second detection component 4 according to an embodiment of the present disclosure is shown schematically.

[0042] Reference Figures 2 to 4The second detection assembly 4 includes a second fixing base 41, a second detection block 42, an input cutting head 44, and a return cutting head 45. The second fixing base 41 is detachably connected to the second detection block 42. When the second detection block 42 is connected to the second fixing base 41, a second receiving cavity 43 is formed between the lower surface of the second detection block 42 and the upper surface of the second fixing base 41. The input cutting head 44 and the return cutting head 45 are both located on the side of the second detection block 42 facing the second fixing base 41, and both are located within the second receiving cavity 43. The input cutting head 44 is electrically connected to the current output terminal of the detection device 2 via a line, and the return cutting head 45 is electrically connected to the current input terminal of the detection device 2 via a line. When the second detection assembly 4 is set at the second position of the traction belt 1, the traction belt 1 passes through the second receiving cavity 43, and the second detection block 42 and the second fixing base 41 are clamped on the upper and lower surfaces of the traction belt 1.

[0043] For example, the second fixing seat 41 and the second detection block 42 can be connected by bolts. When the bolts on the second fixing seat 41 and the second detection block 42 are tightened, the second detection block 42 will press against the second fixing seat 41, causing the input cutting head 44 and the return cutting head 45 on the second detection block 42 to cut through the surface of the traction belt 1 and then make contact with the steel core inside the traction belt 1 to conduct electricity. In this embodiment, when the traction belt 1 passes through the second receiving cavity 43, the input cutting head 44 contacts and conducts electricity with the first steel core 11, and the return cutting head 45 contacts and conducts electricity with the second steel core 12. At this time, the current output by the detection device 2 forms the following path: the current flows out from the current output terminal of the detection device 2, passes through the input cutting head 44, the first steel core 11, the first detection component 3, the second steel core 12, and the return cutting head 45 in sequence, and returns to the current input terminal of the detection device 2. By detecting the continuity of the current in this path, it can be determined whether the steel core of the traction belt 1 is damaged.

[0044] According to an embodiment of this disclosure, a second positioning protrusion 411 is provided on the second fixing base 41, and a second positioning groove 421 is provided on the second detection block 42 to cooperate with the second positioning protrusion 411. (Refer to...) Figure 2 and Figure 3 The second positioning protrusion 411 is disposed on the side of the second fixed seat 41 facing the second detection block 42. When the second fixed seat 41 and the second detection block 42 are engaged, the second positioning protrusion 411 is inserted into the second positioning groove 421. The provision of the second positioning protrusion 411 and the second positioning groove 421 can guide the second fixed seat 41 and the second detection block 42 to quickly align, reducing the installation time of the second detection assembly 4.

[0045] In some exemplary embodiments, the second positioning protrusion 411 may be interference-fitted with the second positioning groove 421, which can improve the stability of the connection between the second fixing seat 41 and the second detection block 42.

[0046] According to an embodiment of this disclosure, a second corrugated groove 412 is provided on the side of the second fixing seat 41 facing the second receiving cavity 43. When the traction belt 1 passes through the second receiving cavity 43, the traction belt 1 is embedded in the second corrugated groove 412. (Refer to...) Figure 3 The second corrugated groove 412 extends along the length of the traction belt 1. When the traction belt detection device of this embodiment is used to detect multi-wedge belts, the triangular wedges on the surface of the multi-wedge belt can be embedded in the second corrugated groove 412, which facilitates the installation and positioning of the multi-wedge belt and prevents the multi-wedge belt from moving in the horizontal direction, thus causing inaccurate detection results.

[0047] Among them, the aforementioned "multi-wedge belt" is also known as a multi-V traction belt, which refers to a series of longitudinal triangular wedge-shaped belts attached to a flat belt substrate.

[0048] According to an embodiment of this disclosure, a wiring groove 423 is provided on the side of the second detection block 42 facing away from the second fixed base 41. Two wiring holes 424 are provided within the wiring groove 423. The detection device 2 is electrically connected to the input cutting head 44 and the return cutting head 45 via the two wiring holes 424, respectively. (Refer to...) Figure 4 A wiring groove 423 is located on the top of the second detection block 42. A wiring hole 424 penetrates the second detection block 42, with its upper end communicating with the wiring groove 423 and its lower end communicating with the second receiving cavity 43. The current output and current input lines of the detection device 2 can be connected to the wiring groove 423 and electrically connected to the current input head 44 and the current return head 45 respectively through the two wiring holes 424. Furthermore, a wire clamp is provided in the wiring groove 423 to fix the lines, which can organize the lines, prevent them from becoming messy, and protect them from damage.

[0049] Figure 5 A schematic diagram of the structure of the second limiting rib 422 according to an embodiment of the present disclosure is shown.

[0050] Reference Figure 5 According to an embodiment of this disclosure, a second limiting rib 422 is provided on the side of the second detection block 42 facing the second receiving cavity 43. The second limiting rib 422 extends into the second receiving cavity 43, and there is a gap between the second limiting rib 422 and the upper surface of the second fixing seat 41, which should be not less than the thickness of the traction belt 1. Providing the second limiting rib 422 can limit the traction belt 1 in the vertical direction, and at the same time can prevent abnormal materials adhering to the surface of the traction belt 1 from entering the second receiving cavity 43, thus avoiding interference with the detection process.

[0051] Figure 6 A perspective structural view of the first detection component 3 according to an embodiment of the present disclosure is schematically shown; and Figure 7 A cross-sectional view of the second detection component 4 according to an embodiment of the present disclosure is shown schematically.

[0052] Reference Figure 6 and Figure 7 According to an embodiment of this disclosure, the first detection component 3 includes a first fixing base 31 and a first detection block 32, which is detachably connected to the first fixing base 31. For example, the first detection block 32 and the first fixing base 31 can be connected by bolts. When the first detection block 32 is connected to the first fixing base 31, a first receiving cavity 33 is formed between the lower surface of the first detection block 32 and the upper surface of the first fixing base 31. When the first detection component 3 is positioned at a first position of the traction belt 1, the traction belt 1 passes through the first receiving cavity 33, and the first detection block 32 and the first fixing base 31 are clamped on the upper and lower surfaces of the traction belt 1. In this embodiment, the first detection component 3 is used to electrically connect the first steel core 11 and the second steel core 12 at the first position, so that the current output by the detection device 2 can smoothly form a path.

[0053] According to an embodiment of this disclosure, a first positioning protrusion 311 is provided on the first fixing base 31, and a first positioning groove 321 is provided on the first detection block 32 to cooperate with the first positioning protrusion 311. (Refer to...) Figure 6 and Figure 7 The first positioning protrusion 311 is disposed on the side of the first fixed seat 31 facing the first detection block 32. When the first fixed seat 31 and the first detection block 32 are engaged, the first positioning protrusion 311 is inserted into the first positioning groove 321. The first positioning protrusion 311 and the first positioning groove 321 can guide the first fixed seat 31 and the first detection block 32 to be quickly aligned, reducing the installation time of the first detection component 3.

[0054] In some exemplary embodiments, the first positioning protrusion 311 may be interference-fitted with the first positioning groove 321, which can improve the stability of the connection between the first fixing seat 31 and the first detection block 32.

[0055] According to an embodiment of this disclosure, a first limiting rib 322 is provided on the side of the first detection block 32 facing the first receiving cavity 33. The first limiting rib 322 extends into the first receiving cavity 33, and there is a gap between the first limiting rib 322 and the upper surface of the first fixing seat 31, which should be not less than the thickness of the traction belt 1. Providing the first limiting rib 322 can limit the traction belt 1 in the vertical direction, and at the same time can prevent abnormal materials adhering to the surface of the traction belt 1 from entering the first receiving cavity 33, thus avoiding interference with the detection process.

[0056] According to an embodiment of this disclosure, a first corrugated groove 312 is provided on the side of the first fixing seat 31 facing the first receiving cavity 33. When the traction belt 1 passes through the first receiving cavity 33, the traction belt 1 is embedded in the first corrugated groove 312. (Refer to...) Figure 7The first corrugated groove 312 extends along the length of the traction belt 1. When the traction belt detection device of this embodiment is used to detect multi-wedge belts, the triangular wedges on the surface of the multi-wedge belt can be embedded in the first corrugated groove 312, which facilitates the installation and positioning of the multi-wedge belt and prevents the multi-wedge belt from moving in the horizontal direction, thus causing inaccurate detection results.

[0057] Figure 8 The diagram illustrates the current direction of a traction belt detection device according to an embodiment of the present disclosure.

[0058] Reference Figures 2 to 8 According to embodiments of this disclosure, at least two more steel cores are included between the first steel core 11 and the second steel core 12 of the traction belt 1. These at least two steel cores, together with the first steel core 11 and the second steel core 12, form a steel core unit to be tested. The first detection component 3 further includes at least two first conductive clips 34, which are disposed on the first detection block 32 and located within the first receiving cavity 33, for electrically connecting two adjacent steel cores within the steel core unit to be tested. The second detection component 4 further includes at least one second conductive clip 46, which is disposed on the second detection block 42 and located within the second receiving cavity 43, for electrically connecting two adjacent steel cores within the steel core unit to be tested. The first conductive clips 34 and the second conductive clips 46 are staggered in the width direction of the traction belt 1, so that the current output from the current output terminal circulates between the second position and the first position, forming a current path between the input cutting head 44 and the return cutting head 45. The traction belt detection device in this embodiment is suitable for detecting traction belts 1 comprising multiple steel cores.

[0059] Specifically, the traction belt 1 includes a test steel core unit composed of at least two steel cores, a first steel core 11, and a second steel core 12; that is, the test steel core unit includes at least four steel cores. The first detection component 3 includes at least two first conductive clips 34, which are fixed to the side of the first detection block 32 facing the first fixing seat 31, and extend into the first receiving cavity 33. When the first detection component 3 is installed on the traction belt 1, tightening the bolts on the first detection block 32 and the first fixing seat 31 causes the first detection block 32 to press against the first fixing seat 31, which in turn causes the first conductive clips 34 to press down and cut through the surface of the traction belt 1, thereby making contact with the steel cores for conductivity. The second detection component 4 includes at least one second conductive clip 46, which is fixed to both sides of the second detection block 42 facing the second fixing seat 41, and extends into the second receiving cavity 43. When the second detection component 4 is installed on the traction belt 1, the second detection block 42 can be pressed against the second fixed seat 41 by tightening the bolts on the second detection block 42 and the second fixed seat 41. Then the second conductive clamp 46 will press down and cut open the surface of the traction belt 1 so as to make contact with the steel core and conduct electricity.

[0060] Furthermore, refer to Figure 8 As shown, each first conductive clip 34 is used to connect two adjacent steel cores located at the first position, and each second conductive clip 46 is used to connect two adjacent steel cores located at the second position. Furthermore, the number of first conductive clips 34 is one more than the number of second conductive clips 46, and the first conductive clips 34 and second conductive clips 46 are staggered in a direction parallel to the width of the traction belt 1. Therefore, the current output from the current output terminal can circulate between the second and first positions. That is, the current input to the input current cutter head 44 can return to the return current cutter head 45 after passing through all the steel cores in the steel core unit under test, all the first conductive clips 34, and all the second conductive clips 46, thus forming a current path between the input current cutter head 44 and the return current cutter head 45. Through the above structural design, the traction belt detection device of this embodiment can be adapted to detect traction belts 1 containing multiple steel cores.

[0061] In an exemplary embodiment, two steel cores are included between the first steel core 11 and the second steel core 12. These two steel cores are designated "Steel Core One" and "Steel Core Two" along the direction from the first steel core 11 to the second steel core 12. That is, the steel core unit under test includes four steel cores: the first steel core 11, "Steel Core One," "Steel Core Two," and the second steel core 12. At this time, two first conductive clips 34 are provided in the first detection assembly 3. These two first conductive clips 34 are designated "Conductive Clip One" and "Conductive Clip Two" along the direction from the first steel core 11 to the second steel core 12. A second conductive clip 46 is provided in the second detection assembly 4. When the detection device 2 inputs current to the traction belt 1, the current flows in through the input current cutter head 44, sequentially passing through the first steel core 11, "Conductive Clip One," "Steel Core One," the second conductive clip 46, "Steel Core Two," "Conductive Clip Two," and the second steel core 12, and then flows out through the return current cutter head 45, thus forming a current path, which can then be detected by the detection device 2.

[0062] According to embodiments of this disclosure, at least two first conductive clips 34 are arranged along a first straight line, wherein the first straight line (not shown in the figure) is parallel to the width direction of the traction belt 1. Arranging multiple first conductive clips 34 along a first straight line parallel to the width direction of the traction belt 1 makes the detection boundary of the traction belt 1 to be tested at the first position smoother, which is beneficial for segmented detection of the traction belt 1 and facilitates timely screening of faulty traction belt 1 segments.

[0063] According to embodiments of this disclosure, the input cutting head 44, the return cutting head 45, and at least one second conductive clamp 46 are arranged along a second straight line, wherein the second straight line (not shown in the figure) is parallel to the width direction of the traction belt 1. Arranging the input cutting head 44, the return cutting head 45, and the plurality of second conductive clamps 46 along a second straight line parallel to the width direction of the traction belt 1 makes the detection boundary of the traction belt 1 to be tested at the second position smoother, which is beneficial for segmented detection of the traction belt 1 and facilitates timely screening of faulty sections of the traction belt 1.

[0064] The term "detection boundary" refers to the boundary of the traction belt 1 to be detected; that is, traction belt 1 outside this boundary is not within the detection range.

[0065] It should be understood that the "first straight line" is only used to indicate the relative positional relationship between the multiple first conductive clips 34, and the "second straight line" is only used to indicate the relative positional relationship between the input cutting head 44, the return cutting head 45 and the multiple first conductive clips 34. The "first straight line" and the "second straight line" do not have any practical meaning.

[0066] Figure 9a A side view of the first conductive clip 34 according to an embodiment of the present disclosure is schematically shown; and Figure 9b A top view schematically illustrates the structure of the first conductive clip 34 according to an embodiment of the present disclosure.

[0067] According to embodiments of this disclosure, a first conductive clip 34 is provided with a first contact 341 and a second contact 342, the first contact 341 and the second contact 342 being used for electrical connection with different steel cores, respectively. (Refer to...) Figure 9a and Figure 9b The first conductive clip 34 has a first end and a second end. The first end of the first conductive clip 34 is connected to the side of the first detection block 32 facing the first fixing base 31, and the second end of the first conductive clip 34 extends into the first receiving cavity 33. The second end of the first conductive clip 34 is provided with a first contact 341 and a second contact 342. The first conductive clip 34 and its first contact 341 and second contact 342 are all made of conductive material and are used to connect different steel cores at the first position to form a current path.

[0068] When the first detection component 3 is installed on the traction belt 1, the bolts on the first detection block 32 and the first fixed seat 31 can be tightened to make the first detection block 32 press against the first fixed seat 31. At the same time, the first conductive clip 34 set on the first detection block 32 will cut open the surface of the traction belt 1, thereby making the first contact 341 and the second contact 342 contact the steel core to conduct electricity.

[0069] According to embodiments of this disclosure, the second conductive clip 46 and the first conductive clip 34 have the same structure. The second conductive clip 46 is made of a conductive material and is used to connect different steel cores at the second position to form a current path. It should be understood that the specific structural forms of the first conductive clip 34 and the second conductive clip 46 are not limited to those described above. Figure 9a and Figure 9b As shown in the embodiments disclosed herein, this is not a limitation.

[0070] It should be noted that the traction belt detection device of this disclosure is applicable to the detection of various types of traction belts 1, and is particularly suitable for the detection of elevator traction belts 1. For example, the traction belt detection device can be used to detect multi-wedge type traction belts 1 of elevators. It should be understood that the application of the traction belt detection device in this disclosure is not limited to elevator traction belts 1.

[0071] When the traction belt detection device of this embodiment is used, the specific steps are as follows: According to the detection requirements of the traction belt 1, the first detection component 3 is installed at the first position of the traction belt 1, so that the plurality of first conductive clips 34 in the first detection component 3 contact and conduct electricity with each steel core at the first position; the second detection component 4 is installed at the second position of the traction belt 1, so that the current-infeeding blade 44 and the current-returning blade 45 and the plurality of second conductive clips 46 in the second detection component 4 contact and conduct electricity with each steel core at the second position; thereby, the steel cores between the first position and the second position can be connected to form a current path, and then the detection device 2 inputs current to the steel core of the traction belt 1 and detects whether the current in the current path is normal, so as to determine whether the steel core of the traction belt 1 being detected is damaged.

[0072] The traction belt detection device according to the embodiments of this disclosure has at least one of the following technical effects:

[0073] (1) The present invention adopts a split structure. The first detection component 3 and the second detection component 4 can be installed at any position of the traction belt 1, which is simple to install. Furthermore, the first detection component 3 and the second detection component 4 do not need to be connected by a line, and there is no need to set up extra lines and circuit connection structures, which reduces the cost.

[0074] (2) The present invention utilizes the first conductive clip 34 and the second conductive clip 46 to connect different steel cores to form a current path. The first conductive clip 34 and the second conductive clip 46 can cut open the surface of the traction belt 1 under the action of external force, insert into the interior of the traction belt 1 and then contact the steel core to conduct electricity, ensuring a stable connection with the steel core and making the detection process more stable.

[0075] (3) The traction belt detection device of the present invention can be used to detect traction belt 1 containing multiple steel cores, and can detect whether each steel core is damaged.
