Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to an elevator traction rope wear scanning and measuring instrument. Background Technique

[0002] The traction drive elevator transmits the motion and power of the traction machine by the friction between the traction wheel and the traction rope. Therefore, the traction rope is the key transmission component and load-bearing component of the traction drive elevator. During the operation of the elevator, the traction rope bears the load and moves, and there is wear, resulting in a decrease in diameter, thereby reducing the load-bearing capacity of the traction rope. When the load-bearing capacity of the traction rope drops to a certain extent, it will threaten the safety of elevator use. Therefore, the standard stipulates that when the diameter reduction of the traction rope reaches 10% of the nominal diameter (the original diameter of the traction rope), it should be scrapped; at present, the common measurement method for the wear amount of the traction rope diameter is: artificially judge the severely worn section of the traction rope. This measurement and judgment method takes a point instead of the whole surface and there is a risk of missed judgment.

Brushes are arranged inside the upper arc-shaped mounting plate and the lower arc-shaped mounting plate. A threaded rod is inserted in the middle of one side of the upper box body, and the lower part of the threaded rod is movably connected with a fixing plate. A plurality of mounting seats are arranged at equal intervals below the fixing plate, and rollers are arranged on the mounting seats;

[0004] However, each elevator has multiple traction ropes, the traction ropes are very long and large in number. Under the influence of the movement characteristics of the elevator and the uniform force distribution among the traction ropes at a longer stroke scale, there are differences in the wear of the traction ropes at different positions. Therefore, it is relatively difficult for the above-mentioned prior art to comprehensively measure and judge the wear degree of the traction ropes; and the overall volume of the above-mentioned technology is relatively large, adopting a box structure, resulting in a certain waste of space; its overall is a standard design, non-modular assembly, and its later expandability is also poor. For the measuring device itself, its later maintenance and upgrade are inconvenient. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.

[0030] Reference Figure 1-7 As shown, an elevator traction rope wear scanning and measuring instrument includes a base 1, a substrate 3 mounted on the base 1, a mounting seat 4 detachably connected to the substrate 3, and a plurality of measuring components 2 arranged in the mounting seat 4;

[0031] The measuring component 2 includes a displacement sensor 21 inserted and assembled in the mounting seat 4, a measuring rod 23 connected to the displacement sensor 21, and a measuring head 22 mounted at the end of the measuring rod 23;

[0032] The base 1 and the substrate 3 clamp the traction rope 5. During measurement, the measuring head 22 is in sliding contact with the traction rope 5.

[0033] During the actual operation of the present utility model, the base 1 and the substrate 3 clamp the traction rope 5 and can slide within the length of the traction rope 5; the mounting base 4 mounts several measuring components 2 at the same inclination angle and fixes them on the substrate 3, and then the measuring head 22 scans and measures the traction rope 5.

[0034] The specific process is as follows: When there is no traction rope assembled, each measuring head 22 on the measuring component 2 presses on the base 1, and the measuring surfaces on the base respectively coincide with the measuring surfaces of the corresponding measuring heads 22. At this time, each displacement sensor 21 is set to zero. After the displacement sensor 21 is set to zero, the base 1 and the substrate 3 are disassembled, sleeved on the traction rope 5 rope row and then assembled, so that each traction rope 5 is respectively attached to the base 1 and the measuring head 22, and the measuring heads press against each other. At this time, the data collected by the displacement sensor is the diameter of the corresponding azimuth of the traction rope at this part, and the wear amount of the corresponding traction rope is calculated; since the measuring instrument can slide along the traction rope 5 rope row; therefore, when the elevator runs from the upper and lower end stations to the lower and upper end stations, the traction rope 5 almost passes through the measuring instrument body in its full length, so the measuring instrument body can realize the full-length scan of the wear of the traction rope 5.

[0035] Adopting the present utility model, the structure is concise, the modular construction can reduce the overall volume, the data collected by the sensor is accurate, through the detachable design, the adaptability of the measuring instrument to various traction ropes 5 is improved, the risk management of the traction rope 5 by the operator is improved, and the quality inspection and maintenance efficiency are improved.

[0036] In this embodiment, the base 1 is provided with a clamping table 11 for assembling with the substrate 3, and a rope groove 12 for the traction rope 5 to slide is opened between the clamping tables 11; the rope groove 12 can help the traction rope 5 to slide stably, ensuring the accuracy of the traction rope 5 and the measurement data during the measurement process; in this embodiment, the substrate 3 is detachably installed on the base 1 by bolts passing through the substrate holes 32, and an avoidance arch 31 corresponding to the rope groove 12 is opened at the lower edge of the substrate 3.

[0037] In this embodiment, the rope groove 12 is provided with a rope groove end face 121 in a V shape. When in the non-measurement state, the measuring head 22 abuts against the rope groove end face 121; the V-shaped rope groove 12 can better adapt to the measuring head, and the rope groove end face 121 is the measuring surface of the base 1; it can ensure the stable position of the measuring head 22 in the non-measurement state and ensure that the displacement sensor 21 can be normally zeroed.

[0038] In this embodiment, the mounting base 4 is detachably mounted on both side end faces of the substrate 3 by bolts passing through the mounting holes 41; the mounting base (4) is further provided with a built-in cavity (43), the displacement sensor (21) is mounted on one side of the built-in cavity (43), and the measuring rod (23) is slidably assembled on the other side of the built-in cavity (43); the mounting bases (4) mounted on both side end faces of the substrate (3) are centrosymmetric with the center of gravity of the substrate (3) as the center point; the axes of the two built-in cavities (43) intersect;

[0039] The mounting base 4 is detachably assembled with the substrate 3. Only by quickly disassembling and assembling the mounting base 4, it is convenient for subsequent batch replacement of the measuring assembly 2; the mounting base 4 is mounted in a centrosymmetric manner, ensuring that the built-in cavity 43 arranged obliquely can also be centrosymmetric, thereby ensuring that each traction rope 5 has a measuring assembly 2 for corresponding measurement and testing.

[0040] The mounting base (4) is further provided with a connecting ring (44), and the sensor body (213) is mounted on one side of the built-in cavity (43) by the connecting ring (44); a buffer spring (214) is arranged in the built-in cavity (43), one end of the buffer spring (214) is connected to the connecting ring (44), the other end contacts the measuring rod (23), and the measuring rod (23) contacts the displacement rod (211); a movable groove (231) is formed in the measuring rod (23), and the measuring rod (23) is assembled in the built-in cavity (43) by a guide pin (42) passing through the movable groove (231).

[0041] The inner thread of the connecting ring 44 is used to mount the sensor body 213, and the outer ring is used to assemble and pre-install the buffer spring 214; during installation, the end of the measuring rod 23 extends into the built-in cavity 43 from below, the measuring rod 23 is pressed against the buffer spring 214 and abuts against the movable rod 211 to ensure that the sensor body 213 can obtain displacement changes, and then the guide pin 42 is inserted into the movable groove 231 to complete the assembly; through the movable groove 231, the movement range of the measuring rod 23 can be determined; the use of the guide pin 42 can realize the quick replacement of the measuring rod 23 to meet the installation requirements of various measuring rods 23 and adapt to rope grooves of various sizes.

[0042] The measuring head 22 can be replaced together with the measuring rod 23 to avoid errors and deformations caused by wear of the high-friction measuring head 22.
