Accurate measuring tool for elevator guide rail installation

Abstract

The utility model belongs to the field of elevator guide rails, and particularly relates to an accurate measuring tool for elevator guide rail installation, which comprises a rail calibration ruler body, and a bayonet is arranged at the front end of the rail calibration ruler body. According to the rail calibration ruler, after the rail calibration ruler bodies are installed on the different guide rails respectively, the limiting blocks are pushed to abut against the guide rails through the magnetic force between the electromagnets and the magnetic blocks to fix the rail calibration ruler bodies, and due to the fact that the magnetic force is the same, the installation positions of the rail calibration ruler bodies are completely the same; position deviation caused by manually rotating bolts to fix the rail calibration ruler body is avoided, so that data of follow-up levelness measurement is more accurate, two symmetrical rotating plates are driven by rotating a rotating rod to rotate to the surface of a guide rail, and when the two rotating plates make contact with the guide rail at the same time, two warning lamps can warn constructors at the same time. The problem that the levelness of the rail calibration ruler body is difficult to detect in an observation mode when the rail calibration ruler works in an elevator shaft with a poor view field is avoided.

Description

Technical Field

[0001] The utility model relates to the field of elevator guide rails, in particular to a precise measuring tool for installing elevator guide rails. Background Art

[0002] When installing elevator guide rails, it is necessary to check the parallelism between multiple guide rails to ensure the safety of the guide rails after installation. The commonly used method is to check the parallelism through a track calibration ruler. The operator installs the track calibration ruler directly on the elevator guide rail, and then directly reads the reading of the track calibration ruler to ensure the stability of subsequent elevator operation.

[0003] At present, when installing a track gauge, it is necessary to ensure that the track gauge itself is level. Currently, a bubble level is usually used to directly observe the surface of the track gauge. However, since the work is done in an elevator shaft, the internal field of vision may be poor. Therefore, it is troublesome for construction workers to observe the bubble level, and errors may occur during observation, resulting in inaccurate data, which will reduce the detection accuracy and efficiency, and even worse, may cause safety hazards. Therefore, in view of the above problems, a precise measuring tool for elevator guide rail installation is proposed. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art and avoid potential safety hazards caused by inaccurate detection, the utility model provides a precise measuring tool for installing elevator guide rails.

[0005] The utility model solves the technical problem by adopting a technical solution: an accurate measuring tool for installing elevator guide rails, comprising a rail calibration ruler body, a bayonet is provided at the front end of the rail calibration ruler body, a limiting component is provided inside the bayonet, and a level detection component is provided inside the rail calibration ruler body;

[0006] The limiting component includes a sliding rod slidably connected to the inside of the track gauge body, an inner groove is provided at the top of the sliding rod, a buffer spring is fixedly installed on the inner wall of the inner groove, an electromagnet is fixedly clamped inside the track gauge body near the bayonet, a limiting block is fixedly connected to the left end of the sliding rod, a magnetic block is clamped inside the limiting block, and a clamping block is clamped at the top of the limiting block.

[0007] Preferably, a slide groove is provided inside the track calibration ruler body, the slide groove is connected to the bayonet, and the slide rod is slidably connected inside the slide groove.

[0008] Preferably, one end of the buffer spring away from the inner wall of the inner groove is fixedly mounted on the inner wall of the track calibration ruler body located in the slide groove, and the proximal ends of the electromagnet and the magnetic block have the same magnetic poles. The magnetic force between the electromagnet and the magnetic block pushes the limiting block to abut against the elevator guide rail, ensuring that the force between the limiting block and the elevator guide rail is inconvenient, thereby ensuring the accuracy of subsequent detection data.

[0009] Preferably, the horizontal detection assembly includes a hollow block fixedly installed inside the track calibration ruler body, the interior of the hollow block is rotatably connected to a rotating rod, a gear is fixedly installed on the surface of the rotating rod, sliding blocks are slidably connected to the upper and lower sides of the hollow block, the end of the sliding block close to the interior of the hollow block is fixedly connected to a rack, the upper and lower ends of the hollow block are rotatably connected to a rotating plate, the upper and lower ends of the hollow block are fixedly installed with return springs, the upper and lower ends of the hollow block are fixedly connected with abutment rods, a force sensor is fixedly installed on the left end face of the rotating plate, and a warning light is fixedly connected to the surface of the rotating plate away from the hollow block.

[0010] Preferably, the rotating rod passes through the hollow block and the track gauge body and extends to the outside of the right side of the track gauge body, the gear and rack are meshingly connected, the two sliding blocks and the rack are symmetrical about the axis center of the rotating rod, and when the rotating rod is rotated to drive the two racks to move in opposite directions, the moving distance of the two racks is always the same.

[0011] Preferably, a slot that is adapted to engage with the abutment rod is formed at one end of the rotating plate close to the hollow block, and one end of the return spring away from the hollow block is fixedly connected to the surface of the rotating plate. The force sensor and the warning light are electrically connected through a PLC controller. When the force sensor contacts the guide rail, it receives a signal and drives the warning light through the PLC controller to alert the operator.

[0012] The utility model is beneficial in that:

[0013] The utility model installs a plurality of track calibration ruler bodies on different guide rails respectively, and then uses the magnetic force between the electromagnet and the magnetic block to push the limiting block to abut against the guide rail to fix the track calibration ruler body. Since the magnitude of the magnetic force is the same, the installation positions of the plurality of track calibration ruler bodies are exactly the same, and the position deviation caused by manually rotating the bolts to fix the track calibration ruler body is avoided, so that the subsequent horizontality measurement data is more accurate.

[0014] The rotating rod is used to drive two symmetrical rotating plates to rotate toward the guide rail surface. When the two rotating plates contact the guide rail at the same time, the two warning lights will also alert the construction personnel at the same time, avoiding the difficulty of detecting the horizontality of the track gauge body by observation when working in the elevator shaft with poor visibility, thereby improving the detection accuracy of the track gauge body.

[0024] Reference Figure 1 - Figure 2The limiting component 3 includes a sliding rod 31 slidably connected to the inside of the track gauge body 1, a sliding groove is opened inside the track gauge body 1, the sliding groove is connected to the bayonet 2, the sliding rod 31 is slidably connected to the inside of the sliding groove, an inner groove 32 is opened at the top of the sliding rod 31, and a buffer spring 33 is fixedly installed on the inner wall of the inner groove 32, an electromagnet 34 is fixedly connected to the inside of the track gauge body 1 near the bayonet 2, the left end of the sliding rod 31 is fixedly connected to a limiting block 35, and a magnetic block 36 is clamped inside the limiting block 35, and the buffer spring 33 is fixedly installed on the inner wall of the track gauge body 1 located in the sliding groove at one end away from the inner wall of the inner groove 32, and the proximal ends of the electromagnet 34 and the magnetic block 36 are the same magnetic poles. The magnetic force between the electromagnet 34 and the magnetic block 36 pushes the limiting block 35 to abut against the elevator guide rail, ensuring that the force between the limiting block 35 and the elevator guide rail remains unchanged, thereby ensuring the accuracy of subsequent detection data, and a clamping block 37 is clamped on the top of the limiting block 35.

[0025] Reference Figure 3 - Figure 4 The horizontal detection component 4 includes a hollow block 41 fixedly installed inside the track gauge body 1, a rotating rod 42 is rotatably connected inside the hollow block 41, a gear 43 is fixedly installed on the surface of the rotating rod 42, and sliding blocks 44 are slidably connected to the upper and lower sides of the hollow block 41. The end of the sliding block 44 close to the inside of the hollow block 41 is fixedly connected to a rack 45. The rotating rod 42 passes through the hollow block 41 and the track gauge body 1 to the outside of the right side of the track gauge body 1. The gear 43 and the rack 45 are meshed and connected. The two sliding blocks 44 and the rack 45 are symmetrical about the axis center of the rotating rod 42. When the rotating rod 42 is rotated to drive the two racks 45 to move in opposite directions, the moving distances of the two racks 45 are always the same. The upper and lower ends of the hollow block 41 are rotatably connected A rotating plate 46 is connected, and return springs 47 are fixedly installed on the upper and lower ends of the hollow block 41. Abutment rods 48 are fixedly connected to the upper and lower ends of the hollow block 41. A force sensor 491 is fixedly installed on the left end face of the rotating plate 46. A warning light 492 is fixedly connected to the surface of the rotating plate 46 away from the hollow block 41. A slot that is adapted to be engaged with the abutment rod 48 is provided at one end of the rotating plate 46 close to the hollow block 41, and one end of the return spring 47 away from the hollow block 41 is fixedly connected to the surface of the rotating plate 46. The force sensor 491 and the warning light 492 are electrically connected through a plc controller. When the force sensor 491 contacts the guide rail, it receives a signal itself. At this time, the warning light 492 is driven by the plc controller to alert the operator.

[0026] Working principle: After the operator inserts the magnetic block 36 into the interior of the limiting block 35, the operator then clamps the clamping block 37 on the top of the limiting block 35 so that the magnetic block 36 will not separate from the limiting block 35. At this time, the clamping port 2 is aligned with the guide rail so that the inner wall on the left side of the clamping port 2 abuts against the guide rail. Then, the electromagnet 34 is energized. At this time, the electromagnet 34 will repel the magnetic block 36 and push the limiting block 35 to move to the left. At this time, the limiting block 35 will stretch the buffer spring 33 and abut against the surface of the guide rail. The limiting block 35 will stably limit the track ruler body 1 to abut against the surface of the guide rail.

[0027] Afterwards, the operator manually rotates the rotating rod 42 counterclockwise, at this time, the rotating rod 42 will drive the fixedly connected gear 43 to rotate, and the gear 43 will drive the two meshing racks 45 to move in opposite directions, and the racks 45 will drive the fixedly connected sliding blocks 44 to move, at this time, the two sliding blocks 44 will move in the direction away from each other, and in the process of the movement of the sliding blocks 44, they will first disengage from the abutment rod 48, and at the same time, the sliding blocks 44 will stretch the reset spring 47 and push the rotating plate 46 to rotate, at this time, the two rotating plates 46 at the remaining two ends of the hollow block 41 rotate at the same time, and if the track gauge body 1 is in a horizontal state at this time, the distance between the left sides of the two rotating plates 46 and the guide rail should be equal, that is, when the sliding block 44 pushes the rotating plate 46 to rotate, the force sensors 491 on the left sides of the two rotating plates 46 should contact the guide rail at the same time, that is, at this time, the two warning lights 492 will simultaneously alert the operator, that is, at this time, the track gauge body 1 is in a horizontal state.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
