[0045] like Figure 1 and 2 As shown, an embodiment of the present invention provides a guide rail verticality detection device, including: a simulation detection component, which is arranged on the guide rail 1 after the guide rail 1 is installed and before the car is installed.

[0046] In the embodiment of the present invention, a simulation detection component is arranged on the guide rail 1 after the guide rail 1 is installed and before the car is installed. The simulation detection component is used to simulate the up and down movement of the elevator car to detect the verticality of the guide rail 1. Compared with the prior art, the detection efficiency is high, the operation is simple and convenient, and if there is a problem with the verticality of the guide rail 1, it can be quickly adjusted.

[0047] The simulation detection component includes: two groups of detection frames 2, which are slidably arranged on both sides of the guide rail 1 one by one, and the detection frame 2 includes a sliding plate 21 and a lifting arm 22 connected to the sliding plate 21. The sliding plate 21 and the lifting arm 22 are integrally formed, and the sliding plate 21 and the lifting arm 22 form an angle, which is preferably an acute angle between 85° and 60°. When the lifting arm 22 is tightened, the sliding plate 21 can be tightly attached to the direction of the slide rail; a roller part 4 and a laser emitter 3 are arranged on the sliding plate 21, and the two groups of lifting arms 22 are connected by an elastic member 5; two groups of adjustment arms 6, respectively one The lifting arm 22 is connected to the two groups of adjustment arms 6, and the two groups of adjustment arms 6 are also hinged by a hinged buckle 7; a fixed plate 92 is arranged at the top of the guide rail 1, and is respectively connected to the two groups of guide rails 1, and a motor 9 is arranged thereon, and the motor 9 is arranged in the middle of the fixed plate 92, that is, in the middle of the two groups of guide rails 1, and the output end of the motor 9 is connected to a lifting rope 91, and the lifting rope 91 is connected to the hinged buckle 7; two groups of laser sensors 8 are arranged on one side of the bottom of the guide rail 1, and are respectively arranged one by one below the laser emitter 3; a sensor display panel 100 is used to receive the sensing signal of the laser sensor 8 and generate a deviation curve graph.

[0048] In the embodiment of the present invention, before measurement, the lifting arm 22 is raised to the top of the guide rail 1. When the measurement starts, the rope is released by the motor 9. The detection frame 2 moves downward close to the guide rail 1 under the action of gravity. The laser point of the laser transmitter 3 hits the position of the laser sensor 8, and the jumping position of the laser point under each distance travel is obtained in real time. A deviation curve graph is formed on the sensor display panel 100 to judge the verticality of the guide rail 1. The detection efficiency is high, the speed is fast, and the operation is simple. One person can complete it quickly. At the same time, if there is a problem with the verticality of the guide rail 1, the specific position of the verticality problem can be quickly found according to the distance travel, and quickly adjusted. Furthermore, the two sets of lifting arms 22 are connected by elastic members 5, so that when the two sets of sliding plates 21 move on the guide rail 1, under the action of elastic force, the rolling part is close to the surface of the guide rail 1, thereby ensuring the accuracy of the measurement.

[0049] As a preferred embodiment of the present invention, Figure 1 and 2As shown, an integrally formed connecting plate 221 is provided at the bottom of the lifting arm 22 near the adjusting arm 6, and a connecting hole 222 is provided on the connecting plate 221, and the two ends of the elastic member 5 are respectively connected to the two groups of connecting holes 222 on the connecting plates 221. Specifically, the elastic member 5 can be a spring, a spring sheet, etc., and is a spring in the embodiment of the present invention. Since the angle between the lifting arm 22 and the sliding plate 21 is an acute angle, the connecting plate 221 is provided at the bottom of the lifting arm 22 near the adjusting arm 6, and the connecting plate 221 extends downward at an angle. When the elastic member 5 connects the two groups of connecting plates 221, the elastic force provided by the spring is exactly perpendicular to the sliding plate 21 in direction, so that the roller part 4 on the sliding plate 21 can be close to the surface of the guide rail 1, thereby ensuring the measurement accuracy.

[0050] As a preferred embodiment of the present invention, Figure 1 and 2 As shown, the lifting arm 22 is provided with a plurality of first waist holes 223, and the adjusting arm 6 is provided with a plurality of second waist holes 61, and the lifting arm 22 and the adjusting arm 6 are connected by locking bolts passing through the first waist holes 223 and the second waist holes 61. Specifically, in the embodiment of the present invention, the position of the adjusting arm 6 can be adjusted through the first waist holes 223 and the second waist holes 61, so that the hinge buckle 7 of the adjusting arm 6 can be located just below the motor 9, and when the lifting rope 91 is released, it is ensured that the two groups of detection frames 2 move downward at the same time.

[0051] As a preferred embodiment of the present invention, Figure 1 and 2 As shown, the roller part 4 includes four groups of side rollers 401, which are arranged side by side and rotated on the sliding plate 21 in pairs; two groups of back rollers 402 are rotatably connected to the sliding plate 21, and are respectively arranged on the upper and lower sides of the side rollers 401. Optionally, two groups of avoidance openings 211 are arranged on the sliding plate 21, and the avoidance openings 211 are arranged one-to-one with the back rollers 402, and the avoidance openings 211 are used to avoid the back rollers 402. Specifically, in the embodiment of the present invention, the guide rail 1 is usually a T-shaped guide rail 1, and the back rollers 402 and the side rollers 401 just wrap the entire surface of the guide rail 1 to ensure the measurement accuracy.

[0052] As a preferred embodiment of the present invention, Figures 1 to 3As shown, a sensing area is provided on the laser sensor 8, which includes a mutually perpendicular transverse line 801 and a longitudinal line 802, the intersection of the transverse line 801 and the longitudinal line 802 is a laser dot 803, and the transverse line 801, the longitudinal line 802 and the laser dot 803 divide the sensing area into a default sensing qualified area 804, a transverse positive and longitudinal positive sensing area 805, a transverse negative and longitudinal positive sensing area 806, a transverse positive and longitudinal negative sensing area 807 and a transverse negative and longitudinal negative sensing area 808, and the default sensing qualified area 804 is within a distance range of 2.0 mm from the laser dot 803. Specifically, when starting to measure, it is necessary to make the laser point of the laser emitter 3 coincide with the laser dot 803. The laser dot 803, the horizontal line 801 and the vertical line 802 divide the sensing area into a default sensing qualified area 804, a horizontal positive and vertical positive sensing area 805, a horizontal negative and vertical positive sensing area 806, a horizontal positive and vertical negative sensing area 807 and a horizontal negative and vertical negative sensing area 808. When the laser point jumps in the corresponding sensing area, a sensing mark point will be formed, and a deviation curve graph will be generated on the sensor display panel 100 to judge the verticality of the guide rail 1. At the same time, if there is a problem with the verticality of the guide rail 1, the specific position with the verticality problem can be quickly found according to the distance travel, and quickly adjusted.

[0053] The embodiment of the present invention provides a detection method of the guide rail verticality detection device described above, comprising the following steps:

[0054] After the guide rail 1 is installed and before the car is installed, the simulation detection component is installed on the guide rail 1;

[0055] Before measuring, lift the lifting arm 22 to the top of the guide rail 1 and below the motor 9;

[0056] Turn on the laser emitter 3, ensure that the laser spot emitted by the laser emitter 3 overlaps with the laser dot 803 on the laser sensor 8, and adjust the transverse line 801 of the laser sensor 8 so that the transverse line 801 is parallel to the guide rail 1. Specifically, the guide rail 1 is a T-shaped guide rail 1, which includes a transverse guide rail surface and a longitudinal guide rail surface. It is necessary to ensure that the transverse guide rail 1 surface is parallel to the transverse line 801;

[0057] Start measuring, start the motor 9, the motor 9 contains a rotary encoder, the signal of the rotary encoder is transmitted to the laser sensor 8 at the same time, the motor 9 releases the rope, the lifting arm 22 slides down along the guide rail 1 under its own gravity, the rotary encoder is used to provide rotation data to obtain the distance stroke H, the laser sensor 8 senses and obtains the jumping position of the laser point in the sensing area at each distance stroke distance H in real time;

[0058] The lifting arm 22 moves to the bottom of the guide rail 1, and the measurement is completed. The sensor display panel 100 generates a lateral deviation curve graph and a longitudinal deviation curve graph according to the distance stroke H and the position of the laser point in the sensing area. The horizontal coordinates of the lateral deviation curve graph and the longitudinal deviation curve graph are the stroke position H, and the vertical coordinates are the lateral deviation value and the longitudinal deviation value respectively; preferably, positive qualified lines and negative qualified lines are set on the lateral deviation curve graph and the longitudinal deviation curve graph, that is, positive qualified values ​​and negative qualified values ​​are set.

[0059] The drawing principle of the horizontal deviation curve graph and the vertical deviation curve graph is as follows: for example, take a point at a certain time T1 on the laser sensor. This point is similar to the XY plane coordinate line. There is a horizontal value X1 and a vertical value Y1 on it. X1 can be judged to be a positive or negative value according to the area where it is located. The same is true for Y1. At time T1, the distance travel H of the laser transmitter 3 downward can be calculated according to the rotary encoder data, so as to calculate the travel position H1. At this time, a point can be drawn on the horizontal deviation curve graph with H1 on the horizontal coordinate and X1 on the vertical coordinate, and then each point at each position (H2, X2), (H3, X3), (H4, X4)... Each continuous point constitutes a curve, and the distance travel H and Y vertical deviation curves are similar;

[0060] The verticality of the guide rail 1 is determined based on the lateral deviation curve graph and the longitudinal deviation curve graph.

[0061] Specifically, Figure 4 and Figure 5 As shown, Figure 4 The sensor display panel 100 shows a qualified curve diagram. The curve is within the qualified value range, and the verticality of the surface guide rail 1 is qualified. Figure 5 The sensor display panel 100 shows an unqualified curve graph, in which the curve exceeds the qualified value range, and the surface verticality is unqualified. The position where the verticality problem occurs is the position where the curve exceeds the qualified value at the stroke position H on the horizontal axis. At this time, the verticality of the guide rail 1 at the stroke position can be adjusted according to the stroke position of the curve and the value exceeding the qualified value range.

[0062] In the embodiment of the present invention, the motor 9 drives the rope release, the sliding plate 21 moves downward along the guide rail 1, the laser sensor 8 senses the sensing position of the laser point of the laser transmitter 3 at each distance travel in real time, and the sensor display panel 100 generates a lateral deviation curve graph and a longitudinal deviation curve graph according to the distance travel and the position of the laser point in the sensing area. The verticality of the guide rail 1 can be quickly determined according to the lateral deviation curve graph and the longitudinal deviation curve graph, and the detection efficiency is high, the speed is fast, and the operation is simple and can be completed quickly by one person. At the same time, if there is a problem with the verticality of the guide rail 1, the specific position of the verticality problem can be quickly found according to the distance travel, and the guide rail can be quickly adjusted.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
