Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator maintenance technology, and in particular to an elevator guide rail maintenance and rust removal device. Background Technology
[0002] Elevator guide rails are elevator components made of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails, and are available in three cross-sectional shapes: T-shaped, L-shaped, and hollow. While serving a guiding function, the guide rails also bear the impact forces during car and elevator braking, as well as the impact forces during emergency braking of the safety gear. The car of a cabin elevator achieves smooth vertical movement by sliding up and down along the T-shaped elevator guide rails. Because the working surfaces of the elevator guide rails are exposed to the air for a long time, they will rust. Rust powder adheres to the guide rails, which may affect the comfort of elevator operation and the operating performance of the safety gear. Therefore, regular rust removal and maintenance of the elevator guide rails are required.
[0003] Traditional rust removal methods mostly involve maintenance personnel manually grinding or using polishing machines, which is not only time-consuming and physically demanding, but also relatively cumbersome. This not only increases the labor intensity but also raises the difficulty of the maintenance personnel's work and reduces work efficiency. Therefore, an elevator guide rail maintenance and rust removal device is proposed to solve the above problems. Utility Model Content
[0004] (a) Purpose of the utility model
[0005] To address the technical problems existing in the background art, this utility model proposes an elevator guide rail maintenance and rust removal device. By setting up a transverse component, a movable plate, an ear plate, a first cylinder, and a displacement plate, a grinding block can be driven to move, bringing it into contact with the guide rail body. At this time, the elevator car drives the grinding block to move, allowing for thorough grinding and rust removal of the guide rail body. After rust removal is complete, the grinding block's reverse movement disengages it from the guide rail body. This prevents continuous contact between the guide rail body and the grinding block after rust removal, which could cause wear on the guide rail body. The installation component facilitates easy replacement of the grinding block, ensuring efficient rust removal and providing advantages such as thorough grinding of the guide rail.
[0006] (II) Technical Solution
[0007] This utility model provides an elevator guide rail maintenance and rust removal device, including a mounting plate and a guide rail body. A vertical plate is fixedly installed on the bottom of the mounting plate, the guide rail body is located on the right side of the mounting plate, and a grinding mechanism is provided on the right side of the vertical plate.
[0008] The grinding mechanism includes a U-shaped frame fixedly installed on the right side of the vertical plate. A movable plate is provided on the right side of the U-shaped frame. A transverse moving assembly is provided inside the U-shaped frame. The output end of the transverse moving assembly is connected to the movable plate. Two ear plates are fixedly installed on the right side of the movable plate. A first cylinder penetrating to the opposite side of each of the two ear plates is fixedly installed on the opposite side of each of the two ear plates. A displacement plate is fixedly installed on the piston rod of each of the two first cylinders. A T-shaped assembly is provided on the left side of each of the two displacement plates. Two grinding blocks are provided between the opposite sides of the two displacement plates. An installation assembly is provided on the opposite side of each of the two displacement plates. The two displacement plates are respectively connected to the two grinding blocks through two sets of installation assemblies.
[0009] Preferably, the lateral movement assembly includes a second cylinder and two guide rods. The second cylinder is fixedly installed on the right side of the vertical plate and extends to the right side of the U-shaped frame. The piston rod of the second cylinder is fixedly connected to the left side of the movable plate. The two guide rods are both fixedly installed on the left side of the movable plate and extend into the interior of the U-shaped frame. The two guide rods are slidably connected to the U-shaped frame.
[0010] Preferably, both sets of T-shaped components include T-shaped grooves and T-shaped blocks. The two T-shaped grooves are opened on the right side of the movable plate, and the two T-shaped blocks are fixedly installed on the left side of the two ear plates respectively. The two T-shaped blocks are slidably connected to the inside of the two T-shaped grooves respectively.
[0011] Preferably, both sets of mounting components include a U-shaped plate and a plurality of connecting bolts. The two U-shaped plates are respectively fixedly installed on opposite sides of the two ear plates. The two grinding blocks are respectively slidably connected to the interior of the two U-shaped plates. The plurality of connecting bolts are respectively located at the top and bottom of the U-shaped plates and extend into the interior of the grinding blocks. The plurality of connecting bolts are threadedly connected to the grinding blocks.
[0012] Preferably, the guide rail body includes two horizontal grinding surfaces and two vertical grinding surfaces. The opposite sides of the two grinding blocks are in contact with the two horizontal grinding surfaces, and the length of the grinding blocks is greater than the length of the horizontal grinding surfaces. The right sides of the two grinding blocks are in contact with the two vertical grinding surfaces, and the width of the right side of the grinding blocks is greater than the width of the vertical grinding surfaces.
[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0014] This elevator guide rail maintenance and rust removal device, through the installation of a transverse component, a movable plate, an ear plate, a first cylinder, and a displacement plate, can drive the grinding block to move, bringing the grinding block into contact with the guide rail body. At this time, the elevator car drives the grinding block to move, allowing the grinding block to fully grind and remove rust from the guide rail body. After rust removal is completed, the grinding block moves in the opposite direction to disengage from the guide rail body. This prevents the guide rail body from continuously contacting the grinding block after rust removal, which could cause wear on the guide rail body. The installation component facilitates the replacement of the grinding block, ensuring the rust removal efficiency of the grinding block. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] like Figure 1-5 As shown, the present invention proposes an elevator guide rail maintenance and rust removal device, which includes a mounting plate 1 and a guide rail body 2. A vertical plate 3 is fixedly installed at the bottom of the mounting plate 1, the guide rail body 2 is located on the right side of the mounting plate 1, and a grinding mechanism 4 is provided on the right side of the vertical plate 3.
[0025] In this utility model, the grinding mechanism 4 can be installed through the mounting plate 1 and the vertical plate 3, and the grinding mechanism 4 can grind the guide rail body 2. The top of the mounting plate 1 has multiple mounting holes that extend to its bottom. The mounting plate 1 can be installed at the bottom of the elevator car through the multiple mounting holes. Thus, the vertical plate 3 and the grinding mechanism 4 are installed at the bottom of the elevator car through the mounting plate 1. The movement of the elevator car can drive the vertical plate 3 and the grinding mechanism 4 to move. Through the movement of the grinding mechanism 4, the guide rail body 2 is ground and rusted.
[0026] In an optional embodiment, the grinding mechanism 4 includes a U-shaped frame 41 fixedly installed on the right side of the vertical plate 3. A movable plate 42 is provided on the right side of the U-shaped frame 41. A transverse moving component 43 is provided inside the U-shaped frame 41. The output end of the transverse moving component 43 is connected to the movable plate 42. Two ear plates 44 are fixedly installed on the right side of the movable plate 42. A first cylinder 45 is fixedly installed on the opposite side of each of the two ear plates 44, penetrating to its opposite side. A displacement plate 46 is fixedly installed on the piston rod of each of the two first cylinders 45. A T-shaped component 47 is provided on the left side of each of the two displacement plates 46. Two grinding blocks 48 are provided between the opposite sides of the two displacement plates 46. An installation component 49 is provided on the opposite side of each of the two displacement plates 46. The two displacement plates 46 are respectively connected to the two grinding blocks 48 through two sets of installation components 49.
[0027] It should be noted that after the grinding mechanism 4 is installed, the transverse component 43 can drive the movable plate 42 to move to the left or right. The movable plate 42 will drive the two ear plates 44 and their connecting structures to move to the left or right, thereby causing the two grinding blocks 48 to move to the left or right. When the two first cylinders 45 are used, the piston rods of the two first cylinders 45 will drive the two displacement plates 46 to move to the opposite side or the opposite side respectively. Under the action of the mounting component 49, the two displacement plates 46 will drive the two grinding blocks 48 to move to the opposite side or the opposite side respectively. The T-shaped component 47 will guide the displacement plates 46 to ensure the stability of the movement of the displacement plates 46.
[0028] In an optional embodiment, the guide rail body 2 includes two grinding horizontal surfaces 21 and two grinding vertical surfaces 22. The opposite sides of the two grinding blocks 48 are in contact with the two grinding horizontal surfaces 21 respectively. The length of the grinding blocks 48 is greater than the length of the grinding horizontal surfaces 21. The right sides of the two grinding blocks 48 are in contact with the two grinding vertical surfaces 22 respectively. The width of the right side of the grinding blocks 48 is greater than the width of the grinding vertical surfaces 22.
[0029] It should be noted that the two horizontal surfaces 21 can be ground and rust removed by using the two grinding blocks 48 on opposite sides, while the two vertical surfaces 22 can be ground and rust removed by using the two grinding blocks 48 on their right sides.
[0030] In addition, before the guide rail body 2, the two grinding blocks 48 are moved to the right by the transverse component 43, so that the right side of the two grinding blocks 48 respectively contacts the two grinding vertical surfaces 22. By activating the two first cylinders 45, the two grinding blocks 48 are moved to the opposite side, so that the opposite side of the two grinding blocks 48 respectively contacts the two grinding horizontal surfaces 21.
[0031] Specifically, when the right sides of the two grinding blocks 48 are in contact with the two grinding vertical surfaces 22 respectively, the right sides of the grinding blocks 48 can completely cover the grinding vertical surfaces 22. When the opposite sides of the two grinding blocks 48 are in contact with the two grinding horizontal surfaces 21 respectively, the opposite sides of the grinding blocks 48 can completely cover the two grinding horizontal surfaces 21 respectively, thereby ensuring the effectiveness of the guide rail body 2 in grinding and rust removal.
[0032] In an optional embodiment, the transverse assembly 43 includes a second cylinder 431 and two guide rods 432. The second cylinder 431 is fixedly installed on the right side of the vertical plate 3 and extends to the right side of the U-shaped frame 41. The piston rod of the second cylinder 431 is fixedly connected to the left side of the movable plate 42. The two guide rods 432 are both fixedly installed on the left side of the movable plate 42 and extend into the interior of the U-shaped frame 41. The two guide rods 432 are slidably connected to the U-shaped frame 41.
[0033] It should be noted that when the second cylinder 431 is activated, the piston rod of the second cylinder 431 will drive the movable plate 42 to move to the right. The two guide rods 432 can guide the movable plate 42 to ensure the stability of the movable plate 42 during movement.
[0034] In addition, after the guide rail body 2 has been polished and rust removed, the first cylinder 45 is first activated in reverse so that the two polishing blocks 48 move to opposite sides, thereby separating the polishing blocks 48 from the polishing horizontal surface 21. Then the second cylinder 431 is activated in reverse so that the two polishing blocks 48 move to the left, thereby separating the polishing blocks 48 from the polishing vertical surface 22. This prevents the guide rail body 2 from continuing to contact the polishing blocks 48 after the rust removal is completed, which would cause wear to the guide rail body 2.
[0035] In an optional embodiment, both sets of T-shaped components 47 include T-shaped grooves 471 and T-shaped blocks 472. The two T-shaped grooves 471 are both opened on the right side of the movable plate 42, and the two T-shaped blocks 472 are respectively fixedly installed on the left side of the two ear plates 44. The two T-shaped blocks 472 are respectively slidably connected to the inside of the two T-shaped grooves 471.
[0036] It should be noted that the T-slot 471 and T-block 472 can guide and limit the movable plate 42, which can prevent the movable plate 42 from shifting and ensure the stability of the movement of the movable plate 42.
[0037] In an optional embodiment, both sets of mounting components 49 include a U-shaped plate 491 and a plurality of connecting bolts 492. The two U-shaped plates 491 are respectively fixedly mounted on opposite sides of the two ear plates 44. The two grinding blocks 48 are respectively slidably connected to the interior of the two U-shaped plates 491. The plurality of connecting bolts 492 are respectively located at the top and bottom of the U-shaped plates 491 and extend into the interior of the grinding blocks 48. The plurality of connecting bolts 492 are threadedly connected to the grinding blocks 48.
[0038] It should be noted that when the grinding block 48 needs to be replaced, the multiple connecting bolts 492 can be directly rotated. When the multiple connecting bolts 492 are disengaged from the grinding block 48, the grinding block 48 can be removed from the U-shaped plate 491 for easy replacement. When the grinding block 48 needs to be installed, first slide the grinding block 48 into the U-shaped plate 491, and then rotate the multiple connecting bolts 492 in the opposite direction. When the multiple connecting bolts 492 are threadedly connected to the grinding block 48, the grinding block 48 can be fixed by the multiple connecting bolts 492.
[0039] Working principle:
[0040] In use, the elevator guide rail maintenance and rust removal device is installed by mounting plate 1 onto vertical plate 3 and grinding mechanism 4, aligning grinding mechanism 4 with guide rail body 2. First, the second cylinder 431 is activated, causing two grinding blocks 48 to move to the right until their right sides contact the two grinding vertical surfaces 22. Then, the two first cylinders 45 are activated, causing the two grinding blocks 48 to move to opposite sides. When their opposite sides contact the two grinding horizontal surfaces 21, the movement of the elevator car drives the two grinding blocks 48 to grind and remove rust from the guide rail body 2. After grinding and rust removal, the first cylinder 45 is activated in reverse, followed by the second cylinder 431, disengaging the two grinding blocks 48 from the guide rail body 2. This prevents continued contact between the guide rail body 2 and the grinding blocks 48 after rust removal, thus avoiding wear on the guide rail body 2.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
