Description

Technical Field

[0001] This invention belongs to the field of elevator testing technology, specifically relating to a device and method for testing the straightness of elevator tracks. Background Technology

[0002] Elevators have become an indispensable special equipment in people's production and life. Among them, the elevator track, also known as the elevator guide rail, is one of the important components for the normal operation of the elevator. While playing a guiding role, the track also bears the impact force when the car and the elevator brake. Due to its long length and the fact that it is usually spliced ​​together by multiple sections of track through connectors, deformed and bent track will affect the alignment effect of the track assembly. Poor straightness will cause vibration and noise when the elevator car rises and falls, which constitutes an unsafe factor for the elevator. Therefore, it is necessary to test the straightness of the track during production.

[0003] Elevator guide rails, based on elevator operating requirements, mainly include hollow rails, counterweight guide rails (L-shaped guide rails), and solid rails (T-shaped guide rails). Current methods for straightness testing of hollow guide rails require that the straightness of the hollow guide rails include both the X and Y directions. Figure 11 As shown, existing technologies can only measure the straightness of elevator guide rails in one direction at a time, or even only one surface at a time. The data from two directions need to be fitted later, resulting in low measurement efficiency. Furthermore, elevator guide rails are long and narrow, and when measured in a horizontal position, the placement needs to be repeatedly adjusted to ensure that the elevator guide rails are placed correctly, which also results in low work efficiency.

DETAILED DESCRIPTION

[0018] The following detailed description of the application will be further described with reference to the accompanying drawings, it is necessary to point out here that the following detailed description is only used to further illustrate the application, and cannot be understood as limiting the scope of protection of the application, and those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0019] As shown in Figure 1 , Figure 2 , the application provides a kind of detection device of elevator track straightness, comprising: Conveying mechanism 4 is used to convey track body 1, and the track body 1 is hollow guide rail with groove 14; Carrying mechanism 2 includes receiving block 23, material supporting assembly and indexing assembly, the output end of the material supporting assembly is drivingly connected with receiving block 23, the extension direction of the receiving block 23 is consistent with the extension direction of track body 1, and one end of the receiving block 23 is fixedly provided with limiting plate 24, the material supporting assembly is used to drive receiving block 23 to swing between horizontal position and inclined position, the lower end of the track body 1 in inclined state is abutted with limiting plate 24, the receiving part 231 of the receiving block 23 is embedded with the groove 14 of the track body 1, and the output end of the indexing assembly is drivingly matched with the material supporting assembly, and the indexing assembly is used to transfer the track body 1 in inclined state from inclined position to detection area; Detection mechanism 3 is used to detect the straightness of multiple surfaces of track body 1 carried to detection position, and the detection mechanism 3 includes displacement driving assembly and distance sensor 31, the output end of the displacement driving assembly is drivingly connected with distance sensor 31, the displacement driving assembly is used to drive distance sensor 31 to move along the extension direction of track body 1, the number of distance sensor 31 is multiple, and multiple distance sensor 31 is correspondingly arranged with the top surface and the side surface of track body 1.

[0020] It should be noted that, as Figure 9As shown, there are a total of three surfaces on the top and side of the track body 1, that is, the number of distance sensors 31 is three.

[0021] It should be further noted that, as Figure 11 shown, the track body 1 has a top 11, a side 12 and a bottom 13. The axial section of the track body 1 formed by the top 11, the side 12 and the bottom 13 is in a "ji" shape. Among them, the bottom 13 serves as the installation part, and the outer sides of the top 11 and the side 12 serve as the guiding surfaces for the elevator car to move up and down. Therefore, the surfaces of the track body 1 that need to be detected for straightness include the upper top surface of the top 11 in the Y direction and the outer sides of the two sides 12 in the X direction.

[0022] Among them, the hollow rail is mainly applicable to low-speed elevators (usually with a speed ≤ 1.0 m / s), has a hollow structure in cross-section, is usually made by cold bending forming process, and is mostly made of cold-rolled steel plates. It is the lightest type among the three types of guide rails, with light weight, low cost, convenient for transportation and installation, and can reduce the overall load-bearing of the elevator hoistway. [[ID=?]]

[0023] Therefore, in the above embodiment, the material supporting component is used to drive the receiving block 23, and the track body 1 conveyed by the conveying mechanism 4 is swung from the horizontal position to the inclined position, that is, from the horizontal position to the handling position. At this time, under the action of the self-gravity of the track body 1, it slides down obliquely until the lower end of the track body 1 abuts against the limiting plate 24 to position the track body 1. Then, with the cooperation of the indexing component and the material supporting component, the track body 1 in the inclined state is transferred to the detection area (that is, the area other than the handling position), and under the continuous action of the material supporting component, the receiving block 23 receives the track body 1 and swings it back to the horizontal position. At this time, the track body 1 is located at the detection position. Then, driven by the displacement driving component, the multiple distance sensors 31 move along the corresponding surfaces to be detected of the track body 1 to achieve synchronous detection of multiple surfaces and improve the detection efficiency.

[0024] Exemplarily, continue to refer to Figure 3 and Figure 4 , the material supporting component includes a material supporting driving part 27, a swing rod 26 and a sleeve shaft 25. The output end of the material supporting driving part 27 is传动连接 with the swing rod 26. The outer end of the swing rod 26 is rotatably connected with the sleeve shaft 25. The sleeve shaft 25 is fixedly connected with the receiving block 23. The handling mechanism 2 further includes a receiving seat 21. A让位槽 211 is opened on the receiving seat 21. The receiving seat 21 is used to receive the track body 1 in the horizontal position. A guiding plate 22 is further arranged on the receiving seat 21. The paired guiding plates 22 are symmetrically distributed with respect to the让位槽 211 to facilitate guiding the track body 1 conveyed by the conveying mechanism 4 to the receiving seat 21. Among them, the track body 1 is located above the让位槽 211, as Figure 4 It should be noted that the part "传动连接" in the original text seems to be an incorrect or incomplete expression. It might be better to check and correct it in the original content for a more accurate translation. Here, I translated it as "传动连接" as it is, but it may need further clarification.As shown, the receiving block 23 is located in the giving way slot 211, and the upper end surface of the receiving block 23 is lower than the upper end surface of the receiving seat 21, so that under the driving of the material supporting driving member 27, the swing lever 26 drives the sleeve shaft 25 to swing synchronously, the receiving block 23 moves out of the giving way slot 211 and supports the track body 1, and because the inclination degree of the sleeve shaft 25 gradually increases, the tail end of the track body 1 (i.e. the upper end of the track body 1 in the inclined state) is first supported on the receiving block 23, while the lower end of the track body 1 still abuts against the receiving seat 21, and as the receiving block 23 gradually inclines, the track body 1 is gradually and completely supported on the receiving block 23, achieving gentle support of the track body 1, until the receiving block 23 swings to the inclined position, as shown in Figure 6 , so that the track body 1 is completely separated from the receiving seat 21.

[0025] As shown in Figure 2 and Figure 3 , the index assembly includes an index driving member 28 and a mounting seat 29, the output end of the index driving member 28 is drivingly connected with the mounting seat 29, and the material supporting driving member 27 is arranged on the mounting seat 29. For the track body 1 that swings to the inclined position, under the driving of the index driving member 28, the mounting seat 29 and the material supporting assembly thereon are integrally indexed, as shown in Figure 2 , the mounting seat 29 counterclockwise rotates by an angle α to a detection area (i.e. an area above the receiving seat 21 except for the area where the track body 1 is moved), so that under the reverse driving of the material supporting driving member 27, the receiving block 23 drives the positioned track body 1 to swing from the inclined state to the horizontal state, thus achieving the operation process of carrying the track body 1 to the detection position.

[0026] As shown in , the index driving member 28 and the material supporting driving member 27 are driving motors.

[0027] Figure 4 As shown in , the receiving block 23 includes a receiving part 231 and a counterweight part 232, the counterweight part 232 is fixedly arranged at the lower end of the receiving part 231, and the receiving part 231 is embedded with the groove 14 of the track body 1.

[0028] Thus, when the swing lever 26 drives the sleeve shaft 25 to swing from the horizontal position to the inclined position, the receiving part 231 is embedded with the groove 14 of the track body 1, which can stably support the track body 1, and during the supporting process, the track body 1 will not be separated from the receiving block 23; and under the action of the counterweight part 232, the center of gravity of the receiving block 23 is lower than the axis of the sleeve shaft 25, i.e. the counterweight part 232 of the receiving block 23 is always located below the sleeve shaft 25, thereby achieving stable erection of the track body 1 on the receiving block 23, and the track body 1 will not be overturned.

[0029] As shown inFigure 7 The counterweight part 232 is internally provided with a curved groove 233, and a rolling ball 234 is arranged to roll in the curved groove 233. When the bearing block 23 supports the track body 1 to swing, the bearing block 23 in the inclined state makes the rolling ball 234 roll down along the curved groove 233 under the action of gravity. With the rolling ball 234 swinging left and right (relative to the extension direction of the bearing block 23) along the curved groove 233, the counterweight part 232 drives the bearing part 231 and the track body 1 to swing left and right, and further makes the track body 1 stably erected on the bearing block 23.

[0030] It should be noted that the lower end of the counterweight part 232 is provided with a disassembly cover, and the inner side of the disassembly cover is the curved groove 233, so as to facilitate the taking and placing of the rolling ball 234, and the curved groove 233 is provided with a plurality of rolling ball grooves 2331, so as to facilitate the taking and placing of the rolling ball 234. Figure 4 For example, in the orientation shown, the width dimension of the counterweight part 232 is less than the width dimension of the bearing part 231.

[0031] For example, continuing to refer to Figure 8 One side of the bearing seat 21 is provided with a limiting seat 38, and a limiting groove 39 is formed in the limiting seat 38. When the track body 1 is carried to the detection position, the lower end of the counterweight part 232 is limited and clamped with the limiting seat 38 through the limiting groove 39. For the track body 1 carried to the detection position, at this time, the rolling ball 234 rolls to the bottom of the curved groove 233, and no additional inertial force is applied to the counterweight part 232, and with the gradual flattening of the track body 1 and the clamping of the lower end of the counterweight part 232 with the limiting groove 39, the positioning of the bearing block 23 is realized, and then the positioning of the track body 1 at the detection position is realized.

[0032] For example, continuing to refer to Figure 8 The displacement driving assembly includes a lifting displacement assembly and a horizontal sliding assembly. The lifting displacement assembly includes a lifting driving piece 35, a first sliding rail 34, a lifting frame 33, and a frame 32. The output end of the lifting driving piece 35 is transmissionally connected with the lifting frame 33, the lifting frame 33 is slidingly connected on the first sliding rail 34, the frame 32 is installed on the lifting frame 33, and the sensor is installed on the inner side of the frame 32. The sliding direction of the first sliding rail 34 and the lifting frame 33 is a vertical direction. The horizontal sliding assembly includes a sliding driving piece 311, a sliding seat 36, a lead screw 37, and a second sliding rail 310. The first sliding rail 34 is fixedly installed on the sliding seat 36, the sliding seat 36 is threadedly sleeved on the lead screw 37, the input end of the lead screw 37 is transmissionally connected with the sliding driving piece 311, and the side of the sliding seat 36 is slidingly connected with the second sliding rail 310. The sliding direction of the sliding seat 36 and the second sliding rail 310 is consistent with the extension direction of the track body 1.

[0033] The lifting frame 33 is driven to move up and down by the lifting drive 35, so that the frame 32 drives the plurality of distance sensors 31 to move up and down, for example, when moving down, the plurality of distance sensors 31 are displaced to the position shown in Figure 9 , so that the distance sensor 31 is located on the side of the surface of the track body 1 to be detected, and the detection is completed. Then the lifting drive 35 is driven in reverse to move the frame 32 upward; After the distance sensor 31 moves to the detection position, the sliding seat 36 slides along the second sliding rail 310 under the drive of the sliding drive 311, so that the distance sensor 31 moves along the extension direction of the track body 1, and the synchronous detection of the plurality of distance sensors 31 on the plurality of measuring surfaces of the track body 1 is realized.

[0034] For example, the lifting drive 35 is a hydraulic telescopic cylinder, an electric telescopic cylinder, or an electric telescopic cylinder, and the sliding drive 311 is a driving motor.

[0035] It should be noted that, as shown in Figure 1 and Figure 10 , the conveying mechanism 4 includes a conveying drive 41, a conveying plate chain 42, and a baffle 44. The conveying plate chain 42 includes a chain plate and a conveying chain belt. The conveying drive 41 is arranged on a mounting frame 43, and the output end of the conveying drive 41 is drivingly connected with the conveying chain belt. The chain plate is mounted on the conveying chain belt, and the chain plate is used to support the track body 1. The baffle 44 is arranged in pairs, and along the conveying direction of the track body 1, the baffles 44 arranged in pairs are symmetrically arranged on both sides of the track body 1. For example, the conveying drive 41 is a motor.

[0036] It should be noted that, in use, the receiving block 23 is located in the accommodation groove 211, the track body 1 is conveyed to the receiving seat 21 by the conveying mechanism 4, and under the guidance and constraint of the guide plate 22, the track body 1 is located above the accommodation groove 211; Then the material supporting drive 27 is started, the swing rod 26 drives the sleeve shaft 25 to swing counterclockwise (for example, in the direction shown in Figure 5 and Figure 6 ), the receiving block 23 lifts the track body 1 through the groove 14, and under the action of its own gravity, the track body 1 is inclined and slides down, and the lower end of the track body 1 abuts against the limiting plate 24, so as to realize the preliminary positioning of the track body 1. Moreover, in the process of lifting the track body 1, the rolling balls 234 in the curved groove 233 roll, the counterweight part 232 swings, the receiving part 231 drives the track body 1 to swing synchronously, and the track body 1 is stably erected on the receiving block 23; When the track body 1 swings to the inclined position, as shown in Figure 6As shown, then, the rotating driving member 28 is started to drive the carrier assembly on the mounting seat 29 to rotate synchronously until the track body 1 is above the receiving seat 21 to the detection area, then the carrier driving member 27 is started again to drive the track body 1 to swing reversely to the horizontal state, at this time, the lower end of the counterweight part 232 is clamped with the limiting groove 39 to realize the positioning of the receiving block 23, and indirectly the positioning of the track body 1. Then, the lifting driving member 35 is started to drive the lifting frame 33 to move downward to realize the downward movement of the frame 32 with the distance sensor 31 to the position as shown. Figure 9 As shown, then, the rotating driving member 28 is started to drive the carrier assembly on the mounting seat 29 to rotate synchronously until the track body 1 is above the receiving seat 21 to the detection area, then the carrier driving member 27 is started again to drive the track body 1 to swing reversely to the horizontal state, at this time, the lower end of the counterweight part 232 is clamped with the limiting groove 39 to realize the positioning of the receiving block 23, and indirectly the positioning of the track body 1. After the detection is completed, the track body 1 can be taken away, and the receiving block 23 can be reset into the giving-way groove 211 to perform the straightness detection of the next track body 1.

[0037] In another embodiment, the application further provides a detection method for the straightness of an elevator track, which is applied to the detection device for the straightness of an elevator track, and the detection method comprises the following steps. The track body 1 is conveyed to the receiving seat 21 of the carrying mechanism 2 by the conveying mechanism 4, at this time, the receiving block 23 is in the giving-way groove 211, and the giving-way groove 211 is below the track body 1 under the constraint of the guide plate 22. The receiving block 23 is driven by the carrier assembly to swing from the horizontal position to the inclined position, and the track body 1 is lifted by the receiving block 23 through the groove 14, and the lower end of the track body 1 in the inclined state is abutted with the limiting plate 24. The track body 1 in the inclined state is transferred from the inclined position to the detection area by the transmission cooperation of the rotating assembly and the carrier assembly, and the receiving block 23 is driven by the carrier assembly to swing the track body 1 to the detection position. The plurality of distance sensors 31 are driven by the displacement driving assembly to detect the straightness of the plurality of surfaces of the track body 1.

[0038] In the process of transferring the track body 1 in the inclined state from the inclined position to the detection area, the receiving block 23 is driven by the counterweight part 232 through the receiving part 231 to swing eccentrically by the rotating cooperation of the sleeve shaft 25 and the swing rod 26.

[0039] Through the above method, the synchronous detection of the plurality of surfaces of the track body 1 is realized, and before detection, the inclined carrying of the track body 1 by the receiving block 23 is facilitated by the carrying mechanism 2, the track body 1 is abutted against the limiting plate 24, the positioning of the track body 1 is realized, and the center of gravity of the counterweight part 232 is lowered, the track body 1 is swung with the receiving block 23, the central position of the track body 1 compared with the receiving block 23 is adjusted, and the detection accuracy is ensured.

[0040] The above-described embodiments only express several embodiments of the present application, which are described in detail and specifically, but cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
