Description

Technical Field

[0001] The invention relates to the technical field of elevator rail correction, in particular to a straightening device for elevator guide rails. Background Art

[0002] Elevator guide rails are key components in elevator systems. They provide guidance and support for the elevator car and counterweight, ensuring that the elevator can move vertically or tilted safely and smoothly.

[0003] During the operation of the elevator, the connecting parts used to connect the guide rails may become loose due to changes in ambient temperature and / or long-term load, which may cause the joints of the guide rails to be misaligned. In this case, the guide shoe of the car will come into abnormal contact with the misaligned guide rail when passing through the joint of the guide rail, causing vibration / shaking during the operation of the car, affecting the riding comfort and stability; and the abnormal contact between the guide shoe and the misaligned guide rail will also aggravate the wear of the guide shoe, shorten its service life, and affect the normal operation of the elevator.

[0004] In the prior art, the misaligned guide rail joints are corrected by using the "oscillation method". That is, a hammer is used to hit the guide rails during the correction operation, so that the misaligned guide rail joints are aligned under the action of the impact force. However, correcting the guide rails by hitting them easily leads to residual stress on the elevator guide rails, thereby reducing the fatigue strength of the guide rails and shortening the normal service life of the guide rails.

[0005] Therefore, when the elevator guide rail is calibrated, how to reduce or even avoid the stress remaining on the guide rail and ensure the service life of the guide rail is a technical problem that needs to be solved urgently in the prior art. Summary of the invention

After eliminating the pressure applied by the guide rail segment 1 above the first segment to be calibrated 3 on its body, the "oscillation method" is used to correct and straighten the first segment to be calibrated 3. In this way, it can be ensured that the force applied to the first segment to be calibrated 3 can be effectively released, thereby avoiding stress remaining in the first segment to be calibrated 3 and improving the service life of the guide rail segment 1.

[0048] It should be noted that the reference segment 2 in this embodiment is the guide rail segment 1 that has been straightened; when calibrating the second segment to be calibrated 4 and the remaining guide rail segments 1 above it, just follow the above method, which will not be repeated here.

[0049] As a preferred embodiment, based on the above method, further, a first limit ruler 10 and a second limit ruler 11 are provided on the first bearing plate 5, the first limit ruler 10 is used to abut against the guide surface of the reference segment 2, the second limit ruler 11 is used to abut against the side of the bottom plate of the reference segment 2, and the ends of the first limit ruler 10 and the second limit ruler 11 both exceed the top surface of the reference segment 2.

[0050] Specifically, in this embodiment, a first long fixing hole and a second fixing hole are provided on the first bearing plate 5, the central axis of the first fixing hole is perpendicular to the guide surface of the reference segment 2, and the second fixing hole is perpendicular to the side of the bottom plate of the reference segment 2. A first clamping plate is also provided at the bottom of the first limit ruler 10, and a second clamping plate is also provided at the bottom of the second limit ruler 11. The first clamping plate is clamped in the first fixing hole, and the first clamping plate can slide along the first fixing hole. The second clamping plate is clamped in the second fixing hole, and the second clamping plate can slide along the second fixing hole. Fixing bolts are also provided on the first clamping plate and the second clamping plate, and the fixing bolts are used to fix the first clamping plate and the second clamping plate.

[0051] In the present embodiment, the first limit ruler 10 and the second limit ruler 11 are provided. In the operation of straightening the first segment 3 to be calibrated, the first limit ruler 10 and the second limit ruler 11 can be used to more quickly and conveniently determine whether the first segment 3 to be calibrated is aligned with the reference segment 2, thereby improving the convenience of the present invention in actual use; further, the first limit ruler 10 and the second limit ruler 11 can also limit the movable range of the first segment 3 to be calibrated, so as to avoid the first segment 3 to be calibrated from exceeding the set stop position when being struck, thereby speeding up the straightening operation to a certain extent.

[0052] Example 2: Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the elevator guide rail straightening device of the present invention is based on the above method. Further, the left and right sides of the central axis of the guide rail segment 1 are symmetrically provided with bearing blocks 12, and the bearing blocks 12 are arranged on one side of the top of the guide rail segment 1. The bearing blocks 12 are provided with limiting grooves 13.

[0053] The first bearing plate 5 includes a bearing portion 14, a fixing portion 15 and a platform portion 16, the limiting hole is arranged on the bearing portion 14, the first limiting ruler 10 is arranged on the platform portion 16, the second limiting ruler 11 is arranged on the fixing portion 15, and the fixing portion 15 is clamped in the limiting groove 13;

[0054] The platform portion 16 is provided with a slide groove 17, the central axis of which coincides with the central axis of the first bearing plate 5, a slider 18 is provided at the bottom of the first limit ruler 10, the slider 18 is clamped in the slide groove 17, and the slider 18 can slide along the slide groove 17, and a limit rotation shaft 19 is also provided on the slider 18, and the first limit ruler 10 is connected to the limit rotation shaft 19.

[0055] The first position limiting ruler 10 and the platform portion 16 have a first matching form and a second matching form.

[0056] When the first bearing plate 5 is in a horizontal state, the slider 18 slides to the side of the slide groove 17 close to the reference segment 2, so that the first limit ruler 10 abuts against the guide surface of the reference segment 2, and a first matching state is formed between the first limit ruler 10 and the platform portion 16, and in the first matching state, the bottom of the first limit ruler 10 is parallel to the platform portion 16;

[0057] When the adjusting bolt 9 applies pressure on the bearing portion 14 to form the first bearing plate 5 in an inclined state, the slider 18 slides along the slide groove 17 to the side away from the reference segment 2, and the first limit ruler 10 rotates with the limit rotation shaft 19 as the rotation axis. When the slider 18 abuts against the end of the slide groove 17 and the rotation angle of the limit rotation shaft 19 reaches the maximum, a second matching form is formed between the first limit ruler 10 and the platform portion 16, and in the second matching form, an acute angle is formed between the bottom surface of the first limit ruler 10 and the platform portion 16.

[0058] Specifically, in this embodiment, the bearing block 12 is arranged to cooperate with the first bearing plate 5. During the installation operation of the first bearing plate 5, the fixing portion 15 is clamped in the limiting groove 13, so that the first bearing plate 5 can be connected to the reference segment 2, thereby improving the convenience of connecting the first bearing plate 5 with the reference segment 2; and, with this structural arrangement, the fixing of the first bearing plate 5 does not need to occupy the bolt holes on the reference segment 2 and the first segment to be calibrated 3. In actual operation, after the calibration of the first segment to be calibrated 3 is completed, the first bearing plate 5 does not need to be disassembled, and the connection plate can be used to fix the joint of the reference segment 2 and the first segment to be calibrated 3, thereby further improving the convenience of the present invention in actual use;

[0059] On the other hand, in this embodiment, when the push rod 7 applies a downward push force on the first bearing plate 5, the first bearing plate 5 will rotate with the bearing block 12 as a fulcrum, and the first bearing plate 5 itself will change from a horizontal state to an inclined state. When the first limit ruler 10 and the platform portion 16 form a second matching form, the first bearing plate 5 forms a maximum inclination angle. At this time, the downward push force applied by the push rod 7 can make the first limit ruler 10 close to the guide surface of the reference segment 2, thereby avoiding the vibration caused by knocking on the guide rail segment 1 during the correction operation. The fixed position of the first limit ruler 10 is offset, and / or the first segment to be calibrated 3 is prevented from hitting the first limit ruler 10, causing its fixed position to be offset, thereby ensuring the accuracy of alignment between the first segment to be calibrated 3 and the reference segment 2; at the same time, the first limit ruler 10 is tightly attached to the guide surface of the reference segment 2, and can also transfer part of the pressure applied by the top support rod 7 on the bearing part 14 to the platform part 16 through the first limit ruler 10, thereby reducing the risk of deformation and damage of the first bearing plate 5 due to uneven force in actual use.

[0060] As a preferred embodiment, on the basis of the above method, further, taking the connection portion between the first limit ruler 10 and the limit rotating shaft 19 as a dividing line, a filling block 20 is provided on the side of the first limit ruler 10 close to the reference segment 2; when a first matching form is formed between the first limit ruler 10 and the platform portion 16, the filling block 20 abuts against the platform portion 16; when a second matching form is formed between the first limit ruler 10 and the platform portion 16, a gap is formed between the filling block 20 and the platform portion 16, and the bottom of the side of the first limit ruler 10 on which the filling block 20 is not provided abuts against the platform portion 16.

[0061] In this embodiment, the filling block 20 is provided to limit the range of rotation of the first position limit ruler 10, ensuring that when the first position limit ruler 10 and the platform portion 16 form a first matching form, the bottom of the first position limit ruler 10 is always parallel to the platform portion 16, thereby improving the convenience of the first supporting plate 5 during installation.

[0062] As a preferred embodiment, based on the above method, further, when the first position limit ruler 10 and the platform part 16 form the second matching form, the part where the bottom thereof abuts against the platform part 16 is set to a rounded structure. With this structural setting, the pressure of the bottom of the first position limit ruler 10 on the platform part 16 can be dispersed, thereby reducing the risk of deformation and damage of the first position limit ruler 10 and the platform part 16 under pressure.

[0063] Example 3: Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the elevator guide rail straightening device described in the present invention is based on the above method. Further, a suspension component 21 is further provided on the second bearing plate 6, and the suspension component 21 includes a first support rod 22, a second support rod 23 and a pulling rope 24.

A first fixed pulley 25 is provided at the end of the first support rod 22, and a second fixed pulley 26 is provided at the end of the second support rod 23. The pulling rope 24 is clamped between the first fixed pulley 25 and the second fixed pulley. The pulley 26 is in the wheel groove; a winding component 27 is also provided on the segment of the top support rod 7 located below the first bearing plate 5, one end of the pulling rope 24 is connected to the winding component 27, and the other end is connected to the bearing block 12, and the winding component 27 is used to reel in or release the pulling rope 24; the second support rod 23 and the second bearing plate 6 are rotatably connected; an accommodating groove 28 is provided at the end of the first support rod 22, and a support shaft 29 is provided in the accommodating groove 28, the first fixed pulley 25 is rotatably connected to the support shaft 29, and the first fixed pulley 25 can slide along the support shaft 29.

[0064] Specifically, in this embodiment, the pulling rope 24 is provided with a rope buckle at one end connected to the bearing block 12, and the winding component 27 is a winding component; in the operation of correcting the first segment 3 to be calibrated, after the pulling rope 24 is connected to the bearing block 12, the winding component 27 is started to reel in the pulling rope 24, and the pulling rope 24 lifts the first segment 3 to be calibrated upward for a distance, so that a gap is formed at the joint between the first segment 3 to be calibrated and the reference segment 2. During this process, the first support rod 22 will guide the pulling rope 24, so that the segment of the pulling rope 24 from the first fixed pulley 25 to the bearing block 12 generates a horizontal component force perpendicular to the central axis of the top support rod 7, and then the first segment 3 to be calibrated will produce a deviation from the top support rod 7 under the action of the horizontal component force. The displacement in the direction of the support rod 7, so that the guide surface of the first segment to be calibrated 3 can be in close contact with the first limit ruler 10, that is, the alignment operation of the guide surface of the first segment to be calibrated 3 and the guide surface of the reference segment 2 is completed; further, in this embodiment, when the second support rod 23 is rotated clockwise or counterclockwise, the pulling rope 24 exerts a force on the first fixed pulley 25, which can make it slide along the support shaft 29. During this process, the pulling rope 24 segment under the first fixed pulley 25 can drive the first segment to be calibrated 3 to translate to the left or right. When the side surface of the bottom plate of the first segment to be calibrated 3 is adjusted to be in close contact with the second limit ruler 11, the alignment operation of the side surface of the bottom plate of the first segment to be calibrated 3 facing the side surface of the bottom plate of the reference segment 2 is completed.
