Description

Technical Field

[0001] This invention relates to the technical field of elevator polishing, and in particular to an elevator guide rail repair device. Background Technology

[0002] Currently, a safety brake test is required for every elevator after installation. The safety brake inevitably damages the guide rails, causing unevenness on the surface, necessitating grinding and repair.

[0003] If a regular grinding machine is used for grinding, it is difficult to control the amount and precision of grinding, which will result in uneven grinding and ultimately lead to deviations in the thickness of the guide rail, affecting the comfort and lifespan of the elevator.

[0004] For example, patent application CN202322220841.0 describes a rust removal device for elevator guide rails. This patent is a handheld grinder and auxiliary cleaning mechanism, which solves the problem of difficult-to-clean hard rust or impurities when using a handheld grinder to remove rust from elevator rail surfaces. However, this patent is an auxiliary device for a handheld grinder and cannot improve the grinding accuracy.

[0005] For example, patent application CN202421431032.2 describes an elevator guide rail rust removal device. This patent utilizes a drive motor, support frame, grinding components, and transmission components, mounted on the top of the elevator, to achieve rapid and effective grinding and rust removal of the elevator guide rails. This improves work efficiency and reduces the difficulty and labor intensity of manual operation. Furthermore, the elastic telescopic component allows the device to adapt to different specifications of elevator guide rails, making it convenient to use and highly efficient. However, this patent primarily focuses on improving work efficiency and cannot control the grinding precision. Summary of the Invention

[0006] In view of this, in order to solve the above problems, the purpose of this invention is to provide an elevator guide rail repair device, comprising: Drive components, grinding components, clamping components, adjustment fixtures; A housing is mounted on the drive assembly. The housing has a through hole. The output shaft of the drive assembly extends into the housing and is used to mount the grinding assembly. At least a portion of the grinding assembly passes through the through hole and protrudes from the outside of the housing. The outer shell is fixed to the clamping assembly, and at least one first roller, one second roller and one third roller are pivotally mounted on the clamping assembly; The adjustment fixture is equipped with a mounting plate; The clamping assembly is configured to be clamped onto the adjustment fixture. When clamped, at least one of the first rollers and the protruding portion of the grinding assembly abut against the same reference surface of the mounting plate, thereby calibrating that the outer circumferential surface of the first roller and the outer circumferential surface of the grinding assembly are on the same straight line.

[0007] In the aforementioned elevator guide rail repair device, a plurality of mounting rods are provided at the end of the outer casing away from the through hole.

[0008] The elevator guide rail repair device described above includes a clamping assembly comprising: a base plate, a positioning plate, a connecting plate, a fixing plate, a screw, and fixing rings; at least one first roller and the positioning plate are vertically mounted on one surface of the base plate; the connecting plate is adjustablely mounted on the positioning plate via the screw, and a fixed space is defined between the connecting plate and the positioning plate; the second roller is mounted on the lower end of the connecting plate; the fixing plate is vertically mounted on one end of the base plate and located on the side away from the connecting plate; a portion of the fixing plate protrudes from the base plate and is provided with several fixing holes; several fixing rings are correspondingly mounted on the fixing plate; several mounting rods pass through several fixing holes and are locked and fixed by several fixing rings; and the third roller is mounted on the fixing plate via a plate.

[0009] The elevator guide rail repair device described above further includes: a spring; a limiting plate is installed at one end of the screw extending from the positioning plate, the spring is sleeved on the screw, and the two ends of the spring abut against the limiting plate and the positioning plate respectively.

[0010] The elevator guide rail repair device described above includes an adjustment fixture comprising: a base, a connecting rod, a mounting component, and several pressure rods; the mounting plate is vertically mounted on the upper surface of the base, the mounting component is mounted on one surface of the mounting plate via several connecting rods, several pressure rods are mounted on the upper end of the mounting component, the fixing space is clamped to the edge of the mounting plate, and the several pressure rods press against the mounting rods, so that the outer circumferential surface of the first roller and the outer circumferential surface of the grinding assembly are both in contact with the same reference surface of the mounting plate.

[0011] In the elevator guide rail repair device described above, at least one positioning block is installed on the upper end of one surface of the mounting plate, and the protruding parts of the grinding components abut against the positioning block.

[0012] The elevator guide rail repair device described above, wherein the grinding component includes: a grinding wheel; the grinding wheel is sleeved on the output shaft of the drive component.

[0013] In the aforementioned elevator guide rail repair device, a handle is installed on the upper end of the positioning plate.

[0014] In the aforementioned elevator guide rail repair device, the connecting plate is bent, and the upper end of the connecting plate is connected to the positioning plate via several connecting shafts. The second roller is installed at the lower end of the connecting plate.

[0015] A method of using an elevator guide rail repair device, comprising the aforementioned elevator guide rail repair device. Step 1: Install the grinding component onto the output shaft of the drive component, and install the housing onto the drive component, such that a portion of the grinding component protrudes from the outside of the housing through the through hole; Step 2: Secure the outer shell and the drive assembly to the clamping assembly; Step 3: The clamping assembly clamps onto the mounting plate, and the adjusting fixture presses against the outer shell; Step 4: Calibrate the first roller and the grinding component. When at least one of the first rollers and the protruding part of the grinding component are both abutting against the same reference surface of the mounting plate, remove the clamping component, the grinding component and the driving component from the adjustment fixture. Hold the clamping component, and position the elevator guide rail with at least one of the first rollers, one of the second rollers and one of the third rollers. Drive the component and start the grinding component to grind the elevator guide rail.

[0016] The positive effects of the above technical solution compared with the existing technology are: 1. Precise installation and calibration ensure grinding quality and accuracy: By setting up specialized adjustment fixtures and using pressure rods and mounting plates as references, the relative position of the grinding component and the first roller can be precisely calibrated during assembly, ensuring that the grinding surface of the grinding component is accurately aligned with the contact surface of the guide rail. This pre-calibration mechanism effectively avoids grinding misalignment or poor contact caused by manual installation errors, fundamentally guaranteeing the accuracy and quality of grinding.

[0017] 2. Modular structure for easy assembly and maintenance: The drive assembly, grinding assembly, and clamping assembly are assembled into a single, independent module using retaining rings and other fasteners, and then calibrated by adjusting the tooling. This modular design simplifies the installation process of each component and facilitates subsequent disassembly, repair, or replacement of parts.

[0018] 3. Combining high-efficiency adjustability with robust clamping force: This device employs a combination of screw and spring design, achieving a dual advantage in clamping force. On one hand, by adjusting the handle to rotate the screw, the width of the fixing space can be quickly and easily adjusted to accommodate different sizes of guide rails or facilitate installation / disassembly. On the other hand, after clamping, the spring continuously provides a stable and adaptive elastic clamping force, ensuring that the equipment is firmly clamped to the guide rail during grinding. Even with slight vibrations or uneven guide rail dimensions, it remains stable, improving operational safety and reliability. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0028] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0029] like Figures 1 to 7 As shown, an elevator guide rail repair device according to a preferred embodiment is illustrated, which includes: a drive assembly 1, a grinding assembly 2, a clamping assembly 3, and an adjustment fixture 4.

[0030] A housing 5 is mounted on the drive assembly 1. The housing 5 has a through hole 51. The output shaft of the drive assembly 1 extends into the housing 5 and a grinding assembly 2 is mounted thereon. At least a portion of the grinding assembly 2 passes through the through hole 51 and protrudes from the outside of the housing 5. The housing 5 is fixed to a clamping assembly 3. At least one first roller 6, one second roller 7, and one third roller 8 are pivotally mounted on the clamping assembly 3. An adjustment fixture 4 is provided with a mounting plate 41. The clamping assembly 3 is configured to be clamped on the adjustment fixture 4. When clamped, at least one first roller 6 and the protruding portion of the grinding assembly 2 abut against the same reference surface of the mounting plate 41, thereby calibrating that the outer circumferential surface of the first roller 6 and the outer circumferential surface of the grinding assembly 2 are on the same straight line.

[0031] In actual use, the drive component 1 in this device is a motor. When the drive component 1 and the grinding component 2 are installed together, they are mounted on the adjustment fixture 4. Since grinding the elevator guide rail 10 does not involve pressing the grinding component 2 tightly against the elevator guide rail surface, but rather maintaining a constant distance between the grinding component 2 and the elevator guide rail surface, the structure of removing only the protruding parts of the elevator guide rail surface is achieved. The relative positions of the first roller 6 and the grinding component 2 are calibrated by adjusting the fixture 4, ensuring that the outer circumferential surfaces of both the first roller 6 and the grinding component 2 abut against the same reference surface of the mounting plate 41. See [link to details]. Figure 7As shown, this ensures that the position of the grinding component 2 remains constant relative to the grinding surface of the elevator guide rail, unaffected by the machining accuracy such as the perpendicularity of the elevator guide rail 10. After adjusting the relative position of the first roller 6 and the grinding component 2 using the adjusting fixture 4, the first roller 6 and the grinding component 2 are tightened and removed. The operator holds the clamping component 3, which, through the first roller 6, the second roller 7, and the third roller 8, clamps and positions the elevator guide rail 10. The grinding component 2 then starts grinding the elevator guide rail 10.

[0032] In addition to the above, the present invention also has the following embodiments: Furthermore, an elevator guide rail repair device is provided, wherein a plurality of mounting rods 52 are provided at the end of the outer casing 5 away from the through hole 51.

[0033] Furthermore, in an elevator guide rail repair device, the clamping assembly 3 further includes: a base plate 31, a positioning plate 32, a connecting plate 33, a fixing plate 36, a screw 34, and a fixing buckle 35; at least one first roller 6 and the positioning plate 32 are vertically mounted on the same surface of the base plate 31, the connecting plate 33 is adjustablely mounted on the positioning plate 32 by the screw 34, and a fixed space 323 is defined between the connecting plate 33 and the positioning plate 32, the second roller 7 is mounted on the lower end of the connecting plate 33, the fixing plate 36 is vertically mounted on one end of the base plate 31 and located on the side away from the connecting plate 33, a portion of the fixing plate 36 protrudes from the base plate 31 and is provided with a plurality of fixing holes 361, a plurality of fixing buckles 35 are correspondingly mounted on the fixing plate 36, a plurality of mounting rods 52 pass through the plurality of fixing holes 361 and are locked and fixed by the plurality of fixing buckles 35, and the third roller 8 is mounted on the fixing plate 36 through a plate 37.

[0034] Furthermore, an elevator guide rail repair device further includes: a spring 39; a limiting plate 38 is installed at one end of the screw 34 extending out of the positioning plate 32, the spring 39 is sleeved on the screw 34, and the two ends of the spring 39 abut against the limiting plate 38 and the positioning plate 32 respectively.

[0035] Specifically, for ease of use, an adjustment handle is installed at the head of the screw 34. The screw 34 is rotated by adjusting the handle, thereby adjusting the relative distance between the connecting plate 33 and the positioning plate 32, that is, the width of the fixed space 323.

[0036] Furthermore, an elevator guide rail repair device includes an adjustment fixture 4 comprising: a base 42, connecting rods, a mounting component 43, and several pressure rods 44. A mounting plate 41 is vertically mounted on the upper surface of the base 42. The mounting component 43 is mounted on one surface of the mounting plate 41 via several connecting rods. Several pressure rods 44 are mounted on the upper end of the mounting component 43. A fixing space 323 clamps the edge of the mounting plate 41, and the pressure rods 44 press against the mounting rod 52, so that the outer circumferential surface of the first roller 6 and the outer circumferential surface of the grinding assembly 2 are both in contact with the same reference surface of the mounting plate 41. Specifically, the pressure rods 44 can be manual or automatic depending on the actual usage.

[0037] Furthermore, in an elevator guide rail repair device, at least one positioning block 45 is installed on the upper end of one surface of the mounting plate, and the protruding portions of the grinding component 2 abut against the positioning block 45. The calibration surface of the positioning block 45 facing the grinding component 2 is coplanar with the reference surface of the mounting plate 41, together forming a flat calibration reference. By setting the positioning block 45, the first roller 6 and the grinding component 2 can simultaneously abut against this coplanar reference, thereby accurately calibrating their relative positions.

[0038] Furthermore, an elevator guide rail repair device includes a grinding component 2 comprising a grinding wheel, which is sleeved on the output shaft of the drive component 1. Specifically, the elevator guide rail 10 is ground by adjusting the surface roughness of the grinding wheel, and the grinding wheel abuts against the positioning block 45.

[0039] Furthermore, an elevator guide rail repair device is provided, wherein a handle is installed on the upper end of the positioning plate 32. In this embodiment, the positioning plate 32 is a bent L-shaped plate, and the handle 9 is installed at the bent position at the upper end of the positioning plate 32, allowing the user to easily polish the elevator guide rail 10.

[0040] Furthermore, in an elevator guide rail repair device, a connecting plate 33 is bent, and the upper end of the connecting plate 33 is connected to a positioning plate 32 via several connecting shafts. A second roller 7 is installed at the lower end of the connecting plate 33. Specifically, the moving stability of the connecting plate 33 is maintained by two connecting shafts located on both sides of the screw 34.

[0041] In this embodiment, a mounting base is provided between the drive assembly 1 and the housing 6. The drive assembly 1 is mounted on one surface of the mounting base by screws, and then the housing 5 is mounted on the other surface of the mounting base. The output shaft of the drive assembly 1 passes through the mounting base and extends into the interior of the housing 5. At this time, the grinding assembly 2 is mounted on the output shaft of the drive assembly 1. When the drive assembly 1 is started, it drives the grinding assembly 2 to rotate, and the elevator guide rail 10 is ground by the roughness of the outer circumferential surface of the grinding assembly 2. After installing the drive assembly 1 and the grinding assembly 2, install them onto the clamping assembly 3. Insert the mounting rods 52 into the corresponding fixing holes 361. Do not tighten the fixing rings 35 at this time. Install the drive assembly 1, the grinding assembly 2, and the clamping assembly 3 onto the adjustment fixture 4. Rotate the screw 34 by adjusting the handle to adjust the relative width of the fixing space 323, so that the fixing space 323 is clamped onto the mounting plate 41. At this time, due to the elastic force of the spring 39, the clamping assembly 3 is clamped onto the adjustment fixture 4. Then, several pressure rods 44 press down on several mounting rods 52, so that the outer circumferential surface of the grinding assembly 2 and the outer circumferential surface of the first roller 6 are on the same straight line. Align the grinding assembly 2, and then tighten it. The fixed buckle 35 locks the drive assembly 1, the grinding assembly 2, and the clamping assembly 3 together. Finally, the width of the fixed space 323 is increased by adjusting the screw 34 through the adjustment handle. The drive assembly 1, the grinding assembly 2, and the clamping assembly 3 are then removed from the adjustment fixture 4. The operator can hold the handle 9 to grind the elevator guide rail 10. During grinding, the width of the fixed space 323 is adjusted again through the adjustment handle. The elevator guide rail 10 is located in the fixed space 323. The adjustment handle is released. Due to the elastic force of the spring 39, the first roller 6 and the second roller 7 clamp the two sides of the elevator guide rail 10 together. The third roller 8 is used to fit the end face of the elevator guide rail 10. The grinding assembly 2 is activated to grind the elevator guide rail 10.

[0042] A method of using an elevator guide rail repair device, comprising the aforementioned elevator guide rail repair device. Step 1: See details Figure 2 As shown, the grinding component 2 is installed on the output shaft of the drive component 1, and the housing 5 is installed on the drive component 1, such that a part of the grinding component 2 protrudes from the outside of the housing 5 through the through hole 51. Step Two; see details below. Figure 5 As shown, the housing 5 and the drive assembly 1 are fixed to the clamping assembly 3; Step 3: See details Figure 1 As shown, the clamping assembly 3 is clamped to the mounting plate 41, and the adjusting fixture 4 presses the outer shell 5. Step 4: See details Figure 7As shown, the first roller 6 and the grinding component 2 are calibrated. When at least one of the first rollers 6 and the protruding part of the grinding component 2 are both abutting against the same reference surface of the mounting plate 41, the clamping component 3, the grinding component 2 and the drive component 1 are removed from the adjustment fixture. The clamping component 3 is held in hand, and at least one first roller 6, one second roller 7 and one third roller 8 are used to position the elevator guide rail 10. The drive component 1 is driven, and the grinding component 2 is started to grind the elevator guide rail 10.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
