Fixation of the traction steel belt 3 is simply realized merely by twisting operation, thereby simplifying a fixing structure.
In an embodiment, the first fastening screw and the second fastening screw are pressed against an outer surface of the traction steel belt 3. A way in which the first fastening screw and the second fastening screw fix the traction steel belt 3 is not limited to pressed against the outer surface of the traction steel belt 3, thefirst fastening screw and the second fastening screw may be inserted inside the traction steel belt 3, or the first fastening screw and the second fastening screw may penetrate through the traction steel belt 3.
In an embodiment, as illustrated in FIG. 3, the circuit board 12 is provided with an output socket
121, and the output socket 121 is electrically connected to the output spring sheets 13 through a conductive line provided in the circuit board 12. By providing the output socket 121, it is easy to integrate lines connecting the respective output spring sheets 13, thereby simplifying a connection structure and facilitating operation.
In an embodiment, as illustrated in FIG. 3, the circuit board 12 is provided with plug holes 122, and one ends of the respective output spring sheets 13 are plugged and welded into the respective plug holes 122. The arrangement of the plug holes 122 can simplify connection between the output spring sheets 13 and the circuit board 12, and welding the output spring sheets 13 in the respective plug holes 122 can prevent poor connection between the output spring sheets 13 and the circuit board 12, ensuring that the detection work can be performed smoothly. Moreover, the arrangement of the plug holes 122 is more convenient for installation and welding of the output spring sheets 13, effectively avoiding welding failure caused by displacement of the output spring sheets 13 during a welding process.

In an embodiment, as illustrated in FIGS. 3 to 5, a limiting surface 113 is provided inside the first base 11 and located above an outlet end of the first installation hole 111, and limiting grooves 114 corresponding to the respective output spring sheets 13 are provided on the limiting surface 113. Non-end parts of the respective output spring sheets 13 are inserted into the respective limiting grooves 114, and one ends of the respective output spring sheets 13 facing away from the circuit board 12 extend to the outlet end of the first installation hole 111. By arranging the limiting surface 113, positions of the output spring sheets 13 can be limited by the limiting grooves 114 on the limiting surface 113, ensuring that the positions of the output spring sheets 13 can be kept corresponding to positions of the corresponding steel wire ropes 31 in the traction steel belt 3 in real time.
In other embodiments, instead of arranging the limiting grooves 114, adhesive may be arranged on the limiting surface 113 to bond the output spring sheets 13 at specified positions, and the adhesive is made of a non-conductive material.
With reference to FIGS. 1, 4 and 6, the output end connection assembly 1 further includes a plurality of pressing members 16 that are spaced apart on one side of the limiting surface 113. The plurality of pressing members 16 are arranged to press the output spring sheets 13 tightly in the respective limiting grooves 114. By arranging the plurality of pressing members 16, the output spring sheets 13 can be pressed at the specified positions. When installed in place, the traction steel belt 3 would squeeze the one ends of the respective output spring sheets 13 away from the circuit board 12, while limitation of the pressing members 16 on the output spring sheets 13 enables the output spring sheets 13 reversely exert elastic forces on the traction steel belt 3, so that the traction steel belt 3 and the output spring sheets 13 are abutted against each other.
In an embodiment, instead of arranging the plurality of pressing members 16, the output spring sheets 13 may be bonded in the respective limiting grooves 114 with the adhesive. Displacement of the output spring sheets 13 is prevented by viscosity of the adhesive, ensuring that the output spring sheets 13 exert sufficient elastic forces on the traction steel belt 3, so that the output spring sheets 13 and the traction steel belt 3 are tightly abutted against each other.
In an embodiment, as illustrated in FIGS. 5 and 6, afirst accommodating groove 115 is concaved on the first base 11 and at the outlet end of the first installation hole 111.

The first notch is detachably provided with a first cover plate 15 for blocking the first notch, and the pressing members 16 are arranged on one side of the first cover plate 15 adjacent to the output spring sheets 13. By arranging thefirst accommodating groove 115 and the first cover plate 15, installation of the output spring sheets 13 can be facilitated. During the installation, the first cover plate 15 is removed to expose the first accommodating groove 115, and then the output spring sheets 13 are installed at the specified positions, and finally the first cover plate 15 is installed in the first accommodating groove 115 to block the first accommodating groove 115. The first cover plate 15 can also block and protect the output spring sheets 13, prevent external components from squeezing the output spring sheets 13, reduce deformation and damage of the output spring sheets 13, and prevent dust from covering side surfaces where the output spring sheets 13 are in contact with the steel wire ropes 31, so as to avoid affecting contact effect.
In the present embodiment, the pressing members 16 are integrally molded with the first cover plate 15. In an embodiment, the pressing members 16 and the first cover plate 15 are integrally molded by plastic injection molding.
In an embodiment, as illustrated in FIGS. 1 and 5, the outlet end of the first installation hole111 is provided with a first limiting bump 17 that limits an insertion depth of the traction steel belt 3. The first limiting bump 17 is arranged on a groove wall of the first accommodating groove 115, and a position of the first limiting bump 17 corresponds to a position between two adjacent steel wire ropes 31. By arranging the first limiting bump 17, when the traction steel belt 3 is inserted into the first installation hole 111 until an end portion of the traction steel belt 3 abuts against the first limiting bump 17, it is indicated that the output spring sheets 13 tightly abut against the end surface of the end portion of the traction steel belt 3. The first limiting bump 17 can protect the output spring sheets 13 and reduce impact of the traction steel belt 3 on the output spring sheets 13.
In an embodiment, the circuit board 12 is fixed on the first base 11 by screws.
In an embodiment, as illustrated in FIGS. 7 to 11, a spring sheet base plate 22 is connected to the second base 21, and one ends of the respective short-circuited spring sheets 23 are connected in series through the spring sheet base plate 22. By arranging the spring sheet base plate 22, all the short-circuited spring sheets 23 can be connected as a whole for easy installation.
In an embodiment, as illustrated in FIGS. 7 and 8, a second accommodating groove 213 is arranged on the second base 21, and the second accommodating groove 213 is provided with a second notch facing to an outlet end of the second installation hole 211. A second cover plate 25 is detachably arranged at the second notch, and configured to package the spring sheet base plate 22 and the short-circuited spring sheets 23 in the second accommodating groove 213. By arranging the second accommodating groove 213 and the second cover plate 25, installation of the short-circuited spring sheets 23 can be facilitated. During the installation, the second cover plate 25 is removed to expose the second accommodating groove 213, and then the short-circuited spring sheets 23 and the spring sheet base plate 22 are installed at the specified positions, and finally the second cover plate 25 is installed in the second accommodating groove 213 to block the second accommodating groove 213. The second cover plate 25 can also block and protect the short-circuited spring sheets 23, prevent external components from squeezing the short-circuited spring sheets 23, reduce deformation and damage of the short-circuited spring sheets 23, and prevent dust from covering side surfaces where the short-circuited spring sheets 23 are in contact with the steel wire ropes 31, so as to avoid affecting contact effect.
In an embodiment, as illustrated in FIG. 9, the second accommodating groove 213 is provided with an installation surface arranged opposite to the second notch. The installation surface is located above the outlet end of the second installation hole 211, and a hot melt column 26 is protruded from the installation surface. The spring sheet base plate 22 is provided with a through hole, and the hot melt column 26 can fix the spring sheet base plate 22 in the second accommodating groove 213 after the hot melt column 26 passing through the through hole and being hot melted. Such structure connected by the hot melt column 26 can reduce a number of connection components, and reduce manufacturing cost. Moreover, connection of the hot melt column 26 after being hot melted is more reliable, which effectively prevents the spring sheet base plate 22 from loosening, thereby preventing the short-circuited spring sheets 23 from being in poor contact with the traction steel belt 3 due to loosening.
In an embodiment, the outlet end of the second installation hole 211 is provided with a second limiting bump 27 that limits an insertion depth of the traction steel belt 3. By arranging the second limiting bump 27, when the traction steel belt 3 is inserted into the second installation hole 211 until an end portion of the traction steel belt 3 abuts against the second limiting bump 27, it is indicated that the short-circuited spring sheets 23 tightly abut against the end surface of the end portion of the traction steel belt 3. The second limiting bump 27 can protect the short-circuited spring sheets 23 and reduce impact of the traction steel belt 3 on the short-circuited spring sheets 23.
In the present embodiment, the first limiting bump 17 and the second limiting bump 27 are provided. In other embodiments, only the first limiting bump 17 may be provided, or only the second limiting bump 27 may be provided.
In the present embodiment, the first cover plate 15 is clamped on the first base 11 by a buckle, and the second cover plate 25 is clamped on the second base 21 by a buckle. A way of buckle connection can reduce difficulty in disassembly and assembly of the first cover plate 15 and the second cover plate 25.
As illustrated in FIG. 12, the present embodiment further provides a detection system. The detection system includes the elevator traction steel belt rope-breakage detection device, and a monitoring module 4, and a fault indicator 6. The fault indicator 6 is connected to the monitoring module 4. The monitoring module 4 is provided with at least one set of socket groups. Each set of socket groups is provided with output end sockets, and the number of output end sockets of each set of socket groups matches the number of steel wire ropes 31 of the traction steel belt 3. The output end sockets is electrically connected in one-to-one correspondence to the output spring sheets 13 on the circuit board 12 of the elevator traction steel belt rope-breakage detection device.
In an embodiment, the fault indicator 6 is an indicator light, and may also be a digital tube, a liquid crystal display, or the like.
In an embodiment, the monitoring module 4 is further provided with a test switch 5 for monitoring whether or not the monitoring module 4 is normal. The test switch 5 is configured to check whether or not the monitoring module 4 is operating normally during elevator maintenance. When the test switch 5 is disconnected, breakage of an external steel wire rope 31 can be simulated, the system detects that a test circuit is blocked, and corresponding alarm information would be displayed, indicating that the monitoring module 4 is operating normally. In a case where the test switch 5 is disconnected and the monitoring module 4 does not provide the corresponding alarm information, it is indicates that there may be a fault in the monitoring module 4 and the monitoring module 4 needs to be repaired or replaced in time, so as to avoid a case where the monitoring module 4 cannot provide an alarm timely and effectively in response to breakage of the steel wire rope 31.
The present embodiment further provides a detection method, which is applied to the above detection system. As illustrated in FIG. 13, FIG. 13 illustrates a flow chart of a detection method in the present embodiment, and the detection method includes the following steps.
In step SI10, an electrical signal is input to any one of output end sockets by the monitoring !0 module 4; and
In step S120, current of the remaining output end sockets is detected, in a case where the current is successfully detected in the remaining output end sockets, it is determined that that steel wire ropes 31 corresponding to the arbitrary output end socket and the remaining output end socket in the traction steel belt 3 are not broken; and in a case where the current fails to be detected in the remaining output end sockets, it is determined that the steel wire ropes 31 corresponding to the arbitrary output end socket and the remaining output end socket in the traction steel belt 3 are broken.
In an embodiment, as illustrated in FIG. 12, an A end of the traction steel belt 3 is a short-circuited end, a B end of the traction steel belt 3 is an output end. A number n of steel wire ropes 31 are provided in the traction steel belt 3. The A end of the traction steel belt 3 is provided with a number n of ends, namely an end Al, an end A2, an end A3, an end A4,..., an end An. The end B of the traction steel belt 3 is provided with a number n of ends, namely an end BI, an end B2, an end B3, an end B4, ... , an end Bn. At the A end of the traction steel belt 3, all the steel wire ropes 31 are short-circuited-connected together by the short-circuited spring sheet 23 and are electrically conductive. At the B end of the traction steel belt 3, all the steel wire ropes 31 are electrically connected to the output end sockets of the monitoring module 4 by the output spring sheets 13, and can independently input and output electrically, without direct electrical connection between each other.
Generally, one elevator has multiple (N) traction steel belts 3. Correspondingly, a number N of socket groups are provided on the monitoring module 4. The number N of socket groups are connected to corresponding the number n of ends of the B end of the traction steel belt 3 respectively.
A test principle is as follows. For example, an electrical signal is input to the end BI, and current at the end B2 is detected at the same time. Normally, the current passes through a loop formed by the end B1-the end Al-the end A2-the end B2. If current at the end B2 can be detected, it means that neither the first steel wire rope 31 nor the second steel wire rope 31 is broken. If the current at the end B2 cannot be detected, it means that either the first steel wire rope 31 or the second steel wire rope 31 is broken. At this moment, the current at end B3 is detected. Normally, the current passes through a loop formed by the end B1-the end Al-the end A3-the end B3. If the current at the end B3 can be detected, it means that the first steel wire rope 31 is not broken, while the second steel wire rope 31 is broken. If the current at the end B3 cannot be detected, it means that the first steel wire rope 31 is broken, while the second steel wire rope 31 is not broken. Here, detecting the current at the end B3 is merely an example. In other embodiments, any one of the end B4, the end B5... and the end Bn may be selected for detection. That is, when it is found that current at two endpoints under test cannot constitute a normal loop, at this moment, it is necessary to test other endpoints other than these two endpoints to confirm a specific position of a broken rope. Testing of remaining steel wire ropes 31 is also followed by analogy, and matching tests are performed in turn according to a preset period.
This detection method adopts a unique current detection manner, which can quickly and accurately detect whether or not the steel wire ropes 31 are broken, improving detection efficiency and accuracy. And the fault indicator 6 of the detection system can visually display which steel wire rope 31 is broken, that is, a broken status of the steel wire rope 31 can be visually displayed, which is convenient for an operator to distinguish and repair and replace in the future. In addition, even if the detection system detects that one of the steel wire ropes 31 is broken, detection on other steel wire ropes 31 is not affect, and the detection system can detect the statuses of all the steel wire ropes 31 in sequence. The monitoring module 4 of the detection system has a self-detection function, ensuring a long-term stable operation of the system.
