DETAILED DESCRIPTION

[0026] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-3 As shown, the utility model provides a guiding device 100, which is installed on a wire rope detection device 1000. The wire rope detection device 1000 is provided with a tubular passage 200 for the wire rope to be tested to pass through, including two cylindrical shells 1 and two friction pads 2; the two cylindrical shells 1 are connected to the wire rope detection device 1000, and are respectively located at the two ends of the tubular passage 200, and each cylindrical shell 1 is coaxially connected to the tubular passage 200; the two friction pads 2 are arranged in a one-to-one correspondence with the two cylindrical shells 1, each friction pad 2 is a cylindrical shape adapted to the cylindrical shell 1, the friction pad 2 is laid on the inner side wall of the corresponding cylindrical shell 1, and is detachably connected to the cylindrical shell 1, the inner diameter of the friction pad 2 is smaller than the diameter of the tubular passage 200, and the friction pad 2 is used to clamp the wire rope to be tested, and under the action of external force, the cylindrical shell 1 and the friction pad 2 slide relative to the wire rope to be tested.

[0028] In the above technical solution, the connection relationship between the cylindrical housing 1 and the wire rope detection device 1000 is not limited, for example, it can be connected by bolts and screw holes or by blocks and slots, and the specific connection method between the friction pad 2 and the cylindrical housing 1 is not limited, for example, it can be connected by bolts and screw holes, or by blocks and slots, as long as the two can be disassembled, the purpose is to facilitate the replacement of the friction pad 2. In some embodiments, the friction pad 2 is made of polytetrafluoroethylene, which has the advantages of small friction loss, low cost and easy use.

[0029] The utility model installs the two cylindrical shells 1 on the wire rope detection device 1000, and the friction pad 2 is installed in each cylindrical shell 1. The friction force between the friction pad 2 and the wire rope is small. For wire ropes of different diameters, only the friction pad 2 needs to be replaced, and the replacement is convenient. At the same time, it also solves the technical problem that the current guide wheel assembly cannot ensure that wire ropes of all diameters always maintain a coaxial state with the circular tubular passage 200, and the wire rope is easily offset, resulting in wear of the wire rope and the inside of the wire rope detection device 1000, and damage to the internal components of the detection device.

[0030] In addition to the above technical effects, the following technical effects are also provided: the guide device 100 includes the two cylindrical shells 1, each of which is coaxially connected to the circular tubular passage 200. When in use, the steel wire rope to be tested passes through the two cylindrical shells 1 and the circular tubular passage 200. Since the inner diameter of the friction pad 2 in the cylindrical shell 1 is smaller than the diameter of the circular tubular passage 200, the two friction pads 2 ensure effective clamping of the steel wire rope, thus preventing the steel wire rope from loosening or falling off during the detection process. This design can effectively prevent the steel wire rope from hitting the inside of the steel wire rope detection device 1000, reduce the risk of damage to the steel wire rope detection device 1000, and extend the service life of the device.

[0031] Another technical effect is that the guide device 100 of the utility model can effectively clamp the steel wire rope to be tested and can slide relatively under the action of external force by setting the two cylindrical shells 1, thereby ensuring that the steel wire rope to be tested maintains a stable direction when passing through the circular tubular passage 200, avoiding the steel wire rope to be tested from deflecting or shaking during the detection process, thereby improving the accuracy and reliability of the detection.

[0032] Furthermore, a rubber pad 3 is provided between the cylindrical shell 1 and the friction pad 2. The rubber pad 3 is laid on the cylindrical shell 1, and the friction pad 2 is laid on the rubber pad 3. The rubber pad 3 is mainly used for shock absorption to avoid inaccurate detection results due to vibration during the wire rope detection process. In some embodiments, the connection relationship between the rubber pad 3, the friction pad 2 and the cylindrical shell 1 is not limited. For example, they can be connected by screws or by means of block and slot.

[0033] In some technical schemes, a limit member 4 is provided at the end of the cylindrical shell 1 away from the wire rope detection device 1000, and the limit member 4 abuts against the ends of the friction pad 2 and the rubber pad 3 away from the wire rope detection device 1000. The present application does not limit the specific structure of the limit member 4. For example, it can be an annular metal sheet, which is fixed to the end of the cylindrical shell 1 away from the wire rope detection device 1000 by screws, and the side of the metal sheet close to the cylindrical shell 1 abuts against the friction pad 2 and the rubber pad 3. It can also be a limit member 4 of other shapes or materials, and is installed at the end of the cylindrical shell 1 away from the wire rope detection device 1000 to abut against the friction pad 2 and the rubber pad 3 to prevent the friction pad 2 and the rubber pad 3 from falling off.

[0034] In the technical solution of the present application, the cylindrical shell 1 includes a first semi-cylindrical shell 11 and a second semi-cylindrical shell 12, and the cylindrical shell 1 is spliced ​​by the first semi-cylindrical shell 11 and the second semi-cylindrical shell 12. In this way, it is convenient to put the cylindrical shell 1 on the outside of the steel wire rope to be tested, and the installation and disassembly are convenient and quick.

[0035] Furthermore, the rubber pad 3 includes a first rubber pad 31 and a second rubber pad 32, wherein the first rubber pad 31 is arranged on the inner side wall of the first semi-cylindrical shell 11, and the second rubber pad 32 is laid on the inner side wall of the second semi-cylindrical shell 12. Since the cylindrical shell 1 is easy to disassemble, the first rubber pad 31 is arranged on the inner side wall of the first semi-cylindrical shell 11, and the second rubber pad 32 is laid on the inner side wall of the second semi-cylindrical shell 12, so when the cylindrical shell 1 is disassembled or installed, the rubber pad 3 is also disassembled or installed, and installation and disassembly are convenient and quick.

[0036] Furthermore, the friction pad 2 includes a first friction pad 21 and a second friction pad 22, wherein the first friction pad 21 is laid on the inner side of the first rubber pad 31, and the second friction pad 22 is laid on the inner side of the second rubber pad 32. Since the cylindrical shell 1 is easy to disassemble, the first friction pad 21 is laid on the inner side of the first rubber pad 31, and the second friction pad 22 is laid on the inner side of the second rubber pad 32, so when the cylindrical shell 1 is disassembled or installed, the friction pad 2 is also disassembled or installed, and installation and disassembly are convenient and quick.

[0037] In some embodiments, the limit member 4 includes a first limit member 41 and a second limit member 42. The first limit member 41 is arranged at the end of the first semi-cylindrical shell 11 away from the wire rope detection device 1000, and abuts against the ends of the first rubber pad 31 and the first friction pad 21 away from the wire rope detection device 1000; the second limit member 42 is arranged at the end of the second semi-cylindrical shell 12 away from the wire rope detection device 1000, and abuts against the ends of the second rubber pad 32 and the second friction pad 22 away from the wire rope detection device 1000. The present application does not limit the specific structure of the limiting member 4. For example, it can be in the shape of a circular ring sheet, a plurality of shift bars or shift blocks, etc., as long as it can be used to abut and limit the friction pad 2 and the rubber pad 3. Since the friction pad 2 and the rubber pad 3 are divided into two parts, in order to better limit the friction pad 2 and the rubber pad 3, the present application also divides the limiting member 4 into two parts, which abut and limit the two parts of the friction pad 2 and the rubber pad 3 one by one.

[0038] In the technical solution of the present application, the rubber pad 3 and the friction pad 2 are fixed in the cylindrical shell 1 by multiple screws 7; an accommodating portion 5 is provided on the outer side of the cylindrical shell 1, and each screw 7 passes through the end of the cylindrical shell 1 located on the outer side of the cylindrical shell 1, and is located in the accommodating portion 5. The present application does not limit the number of the screws 7 and the specific shape of the accommodating portion 5. In some embodiments, four rows of screws 7 may be included, and each row of screws 7 is arranged along the length direction of the cylindrical shell 1, and each row includes, for example, 4, 5 or 6 screws 7 arranged at intervals, and the four rows of screws 7 are four rows arranged at intervals along the circumference of the cylindrical shell 1. At this time, the accommodating portion 5 may include four accommodating cavities, and the four accommodating cavities are arranged at intervals along the circumference of the outer side of the cylindrical shell 1. The four accommodating cavities are arranged one-to-one with the four rows of screws 7, and the end of each row of screws 7 located on the outer side of the cylindrical shell 1 is located in the corresponding accommodating cavity. Of course, the number of rows of the screws 7 is not limited, and it can be 3 rows, 5 rows, 6 rows, etc. The ends of the screws 7 are hidden in the accommodating portion 5 to prevent the screws 7 from hurting people, while also having an aesthetic effect.

[0039] Furthermore, the cylindrical shell 1 and the wire rope detection device 1000 are connected by a connecting plate 6. The present application does not limit the specific shape of the connecting plate 6. For example, it can be an annular plate, which is sleeved on the outside of the cylindrical shell 1 and is located at the end of the cylindrical shell 1 close to the wire rope detection device 1000. The inner side of the annular plate is connected to the cylindrical shell 1, and the outer side is connected to the wire rope detection device 1000. Of course, the specific connection method between the connecting plate 6 and the wire rope detection device 1000 is not limited. They can be connected by means of screws and screw holes. In some embodiments, the connecting plate 6 can also be a rectangular plate or a strip plate, as long as it can realize the connection between the cylindrical shell 1 and the wire rope detection device 1000.

[0040] The present invention also provides a wire rope detection device 1000 , comprising the guide device 100 .

[0041] The wire rope detection device 1000 includes all the technical effects of the aforementioned guide device 100 and has all the beneficial effects of the guide device 100, which will not be described one by one here.

[0042] Usage process: The wire rope detection device 1000 and the guide device 100 are both mounted on the outside of the wire rope to be detected. By moving the wire rope detection device 1000, the wire rope detection device 1000 and the guide device 100 are moved along the length direction of the wire rope to be detected. During the movement, the wire rope detection device 1000 detects the wire rope to be detected. In some embodiments, since the cylindrical shell 1, the friction pad 2 and the rubber pad 3 are all spliced ​​from two parts, the process of mounting the guide device 100 on the wire rope to be detected is to first install the wire rope detection device 1000 on the wire rope to be detected, and then install the first semi-cylindrical shell 11 and the second semi-cylindrical shell 12 one by one on the wire rope detection device 1000. After the installation is completed, the guide device 100 is also clamped on the outside of the wire rope to be detected.
