Description

Technical Field

[0001] This invention relates to the field of elevator counterweight structure technology, and more specifically, to an elevator counterweight guiding device, a counterweight device, and a method for installing the counterweight device. Background Technology

[0002] The counterweight is a component of the elevator traction system, and its function is to reduce the power of the traction motor and the torque on the traction sheave and worm gear. The counterweight typically consists of a counterweight frame, counterweight sheave assembly, counterweight blocks, and guide shoes.

[0003] Chinese Patent Publication No. CN216303013U, Publication Date: April 15, 2022, Invention Title: A Compact Elevator Centering Guide Device, which includes a counterweight guide rail and a guide shoe. The guide shoe includes a support frame fixed on the counterweight frame and a roller rotatably connected to the support frame. The counterweight guide rail is provided with a guide for the roller to roll in the vertical direction and an installation component for installing the counterweight guide rail in the elevator shaft. The above-mentioned counterweight guide device occupies less space and has less noise. However, the guide device in the above application has the following two shortcomings. (1) The above application uses a combination of roller and C-shaped guide rail, so that the roller moves in the C-shaped guide rail. Once the counterweight frame tilts, the roller is easy to get stuck in the guide rail, which not only causes the roller to wear out severely, but also increases the noise. (2) When the guide shoe is replaced or installed in the above application, the centering frame needs to be moved to the top or bottom of the guide rail before the guide shoe can be replaced or installed, which is very inconvenient. Summary of the Invention

[0004] This invention overcomes the following two shortcomings of the existing elevator guide shoes: (1) When the guide shoes move along the C-shaped guide rail, the rollers on the guide shoes are easily stuck in the C-shaped guide rail when the counterweight frame is tilted, thereby increasing the wear of the rollers; (2) When the guide shoes need to be replaced, the counterweight frame needs to be moved to the end of the guide rail before the guide shoes can be replaced, which is very inconvenient. This invention provides an elevator counterweight guide device that can slide smoothly along the guide rail without the problem of the rollers and the guide rail getting stuck; in addition, it can be installed or replaced at any position on the guide rail, which is very convenient to install.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an elevator counterweight guiding device for cooperating with a C-shaped guide rail, wherein the C-shaped guide rail is provided with a guide groove with a single-sided opening, and the elevator counterweight guiding device includes at least a first roller and a second roller, wherein the first roller and the second roller are disposed in the guide groove and the first roller and the second roller respectively cooperate with the opposite sidewalls of the guide groove.

[0006] In this application, by setting at least two rollers and cooperating with C-shaped guide rails, when the counterweight frame moves in the guide groove, the contact between multiple rollers and the guide groove can improve the stability of the movement, allowing the counterweight frame to slide along the guide rail. Compared with a single roller, it will not be stuck due to the tilt of the counterweight frame, preventing the roller from getting stuck in the guide rail due to the tilt of the counterweight frame during operation. This can effectively avoid the adverse effects on the rollers caused by the tilt of the counterweight frame.

[0007] Preferably, the maximum distance between any point on the first roller and any point on the second roller is greater than the width of the guide groove opening, and the diameters of both the first roller and the second roller are smaller than the width of the guide groove opening.

[0008] With the above structural arrangement, when the first roller and the second roller are positioned within the guide groove, the angle between the line connecting the axes of the first roller and the second roller and the horizontal plane is an acute angle. This means that the first roller and the second roller are not on the same horizontal plane when sliding along the guide rail. This ensures that when the counterweight guiding device of this application is installed on the counterweight frame, if the counterweight frame tilts, although one roller may lose contact with the guide rail, the other roller will still maintain sliding contact with the guide rail. This allows the counterweight frame to continue sliding along the guide rail, preventing the roller from getting stuck in the guide rail during operation. It effectively avoids the adverse effects on the rollers caused by the tilting or offset of the counterweight frame, thereby reducing roller friction and increasing the service life of the rollers. In addition, when the first roller and the second roller run in the guide rail, the first roller and the second roller are at different running heights. That is, the positions where the first roller and the second roller contact the guide rail are also at different heights. In other words, the positions where the first roller and the second roller generate sound on the guide rail are also different. This can prevent the first roller and the second roller in the guide rail from resonating, thereby reducing noise. Compared with the existing technology, it has a low noise and vibration effect.

[0009] Preferably, the elevator counterweight guide device further includes a mounting component, wherein the first roller and the second roller are staggered in height within the guide groove, and the mounting component is equipped with a mounting assembly for adjusting the degree of misalignment between the first roller and the second roller.

[0010] The mounting bracket facilitates the installation of the first and second rollers onto the counterweight frame. The mounting bracket allows for the installation of both rollers. The angle of the mounting bracket can be adjusted to control the misalignment of the first and second rollers. Since different guide rails may have different widths on both sides, the mounting bracket ensures that the first and second rollers, once installed on the guide rails, can fit snugly against the side walls of the guide rails, thus improving the stability of the counterweight frame.

[0011] Preferably, the mounting assembly includes two through-holes on the mounting piece, adjusting bolts corresponding to the two through-holes respectively, and several adjusting shims passing through the adjusting bolts; the two through-holes are set in the same direction as the first roller and the second roller.

[0012] The angle at which the mounting component is installed on the counterweight frame can be changed by adjusting the number of corresponding adjusting shims on the two through sections, thereby adjusting the degree of misalignment of the first roller and the second roller to accommodate C-shaped guide rails of different widths.

[0013] Preferably, the mounting component is an L-shaped mounting plate, the connecting part is a horizontal connecting plate set on the L-shaped mounting plate, and the mounting part is a vertical mounting plate set on the L-shaped mounting plate.

[0014] A reinforcing rib is installed between the horizontal and vertical connecting plates to improve overall strength. The vertical mounting plate, horizontal connecting plate, and reinforcing rib combine to form a single integrated structure. This design features simple structure and easy installation.

[0015] This application also provides a counterweight device, including a counterweight frame and the aforementioned elevator counterweight guide device; the elevator counterweight guide device is disposed at the upper and lower ends on both sides of the counterweight frame in the width direction.

[0016] In this application, since the counterweight guide device can be replaced and installed at any position on the guide rail, the centering device in this application has the characteristics of being easy to replace and install.

[0017] Preferably, the upper and lower surfaces of the counterweight frame are provided with mounting bolt holes that mate with the mounting components.

[0018] Each end of the upper and lower end faces along the length direction has a pair of mounting bolt holes, with each pair of mounting bolt holes positioned along the thickness direction of the counterweight frame. The positions of each pair of mounting bolt holes correspond to the through-holes. Then, adjusting bolts are sequentially passed through the through-holes, adjusting shims, and mounting bolt holes for secure connection, thus fixing the elevator counterweight guide device onto the counterweight frame.

[0019] Preferably, it also includes C-shaped guide rails arranged vertically at both ends of the counterweight frame in the width direction, and the C-shaped guide rails are provided with guide grooves that cooperate with the first roller and the second roller.

[0020] The C-shaped guide groove has a certain limiting function, which makes the movement of the first roller and the second roller along the guide groove more stable, thereby making the operation of the entire counterweight frame more stable.

[0021] This application also provides a method for installing a counterweight device, characterized in that it includes the counterweight device described above, and further includes the following steps:

[0022] Step 1: Rotate the elevator counterweight guide device to reduce the length of the horizontal projection of the line connecting the axes of the first roller and the second roller, and place the first roller and the second roller into the C-shaped guide rail.

[0023] Step 2: Rotate the elevator counterweight guide device to increase the length of the horizontal projection of the line connecting the axes of the first roller and the second roller, so that the first roller and the second roller abut against the side walls on both sides of the C-shaped guide rail respectively.

[0024] Step 3: Securely install the elevator counterweight guide device on the counterweight frame.

[0025] In existing technologies, the installation or removal of rollers requires moving the counterweight frame to the bottom or top of the C-shaped guide rail, which undoubtedly increases the difficulty and complexity of replacing and maintaining the guide shoes. However, the installation method described in this embodiment allows the counterweight guiding device to be installed at any position on the C-shaped guide rail, regardless of the counterweight frame's location, effectively improving installation and maintenance efficiency.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] (1) When the counterweight guide device of this application is installed on the counterweight frame, when the counterweight frame tilts, one of the rollers may lose contact with the guide rail, while the other roller will still slide in contact with the guide rail, so that the counterweight frame can still slide along the C-shaped guide rail, thereby effectively avoiding the adverse effects on the rollers caused by the tilting and offset of the counterweight frame, thereby reducing the friction of the rollers.

[0028] (2) When the first roller and the second roller are running in the guide rail, the first roller and the second roller are at different running heights, that is, the first roller and the second roller are at different heights when they contact the C-shaped guide rail. This can prevent the first roller and the second roller in the C-shaped guide rail from resonating, thereby reducing noise. Compared with the prior art, it has low noise and vibration effects.

[0029] (3) In the prior art, when installing or removing the rollers, the counterweight frame needs to be moved to the bottom or top of the guide rail, which undoubtedly increases the difficulty and complexity of replacing and maintaining the guide shoes. When the counterweight guiding device in this application is installed on the guide rail, it can be installed at any position on the guide rail, without being limited by the position of the counterweight frame on the guide rail, which effectively improves the efficiency of installation and maintenance.

[0038] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0039] Example 1: Refer to Figure 1 and Figure 2 As shown, an elevator counterweight guiding device is used to cooperate with a C-shaped guide rail. The C-shaped guide rail has a guide groove with an opening on one side. The elevator counterweight guiding device includes at least a first roller 1 and a second roller 2. The first roller 1 and the second roller 2 are arranged in the guide groove and the first roller 1 and the second roller 2 respectively cooperate with the opposite sidewalls of the guide groove.

[0040] In this application, by setting at least two rollers in cooperation with the C-shaped guide rail 5, the multiple rollers contacting the guide rail 51 when the counterweight frame 4 moves within the guide groove 51 improves the stability of the movement. This allows the counterweight frame 4 to slide along the C-shaped guide rail 5. Compared to a single roller, it will not get stuck due to the tilt of the counterweight frame 4, preventing the roller from getting stuck in the C-shaped guide rail 5 during the operation of the counterweight frame 4. This effectively avoids the adverse effects on the rollers caused by the tilting or offset of the counterweight frame 4. Furthermore, during operation, the smoother operation of the counterweight frame 4 also reduces the noise generated by its movement.

[0041] Example 2: Refer to Figures 1 to 7As shown, an elevator counterweight guiding device is used to cooperate with a C-shaped guide rail 5. The C-shaped guide rail 5 is provided with a guide groove 51 with one side opening. The elevator counterweight guiding device includes at least a first roller 1 and a second roller 2. The first roller 1 and the second roller 2 are arranged in the guide groove 51 and the first roller 1 and the second roller 2 respectively cooperate with the opposite sidewall of the guide groove 51.

[0042] In one embodiment, the first roller 1 and the second roller 2 can be individually fixedly installed on both sides of the counterweight frame 4 in the width direction.

[0043] The first roller 1 and the second roller 2 can be individually fixed on both sides of the counterweight frame 4 in the width direction, which is very inconvenient. In this embodiment, to facilitate the installation and replacement of the first roller 1 and the second roller 2, a mounting component 3 is also included. The mounting component 3 facilitates the installation of the first roller 1 and the second roller 2 on the counterweight frame 4. The first roller 1 and the second roller 2 can be installed on the counterweight frame 4 using the mounting component 3.

[0044] The maximum distance between any point on the first roller 1 and any point on the second roller 2 is greater than the width of the guide groove opening. The diameters of the first roller 1 and the second roller 2 are both smaller than the width of the guide groove opening.

[0045] The elevator counterweight guide device also includes a mounting component 3. The first roller 1 and the second roller 2 are arranged in a staggered manner in the guide groove. The mounting component is equipped with a mounting assembly for adjusting the degree of misalignment between the first roller 1 and the second roller 2.

[0046] The first roller 1 and the second roller 2 are offset, so that the first roller 1 and the second roller 2 are tilted on the side of the counterweight frame 4, that is, the angle between the line connecting the axes of the first roller 1 and the second roller 2 and the horizontal plane is A, 0°. <A<90°。

[0047] Mounting component 3 mainly includes a connecting part 31 and a mounting part 32. The connecting part 31 facilitates connection with the counterweight frame 4, while the mounting part 32 is used to mount the first roller 1 and the second roller 2. In this embodiment, the connecting part 31 is arranged horizontally, and the mounting part 32 is arranged vertically. The first roller 1 and the second roller 2 are located on the end face of the mounting part 32 away from the connecting part 31. The connecting part 31 facilitates the fixing of the mounting component 3 onto the counterweight frame 4, while the mounting part 32 allows the first roller 1 and the second roller 2 to be mounted on the mounting part 32, so that the first roller 1 and the second roller 2 can be mounted on the counterweight frame 4 along with the connection of the connecting part 31 to the counterweight frame 4.

[0048] In one embodiment, a mounting assembly capable of adjusting the included angle A is also provided. The mounting assembly adjusts the angle A between the line connecting the axes of the first roller 1 and the second roller 2 and the horizontal plane by adjusting the angle of the mounting member 3. Since different C-shaped guide rails 5 may have different widths on both sides, in order to ensure that the first roller 1 and the second roller 2, after being mounted on the C-shaped guide rail 5, can respectively fit against the side walls of the C-shaped guide rail 5, thereby improving the stability of the counterweight 4, a mounting assembly capable of adjusting the included angle A is provided. By adjusting the angle of the mounting member 3, the included angle A can be adjusted, thereby adjusting the width of the projection of the first roller 1 and the second roller 2 in the horizontal direction to accommodate C-shaped guide rails 5 of different widths.

[0049] In one embodiment, the mounting assembly includes two through-holes 33 disposed on the mounting member 3, adjusting bolts 34 corresponding to the two through-holes 33 respectively, and a plurality of adjusting shims 35 passing through the adjusting bolts 34; the positions of the two through-holes 33 correspond to the first roller 1 and the second roller 2 respectively. When the mounting member 3 is mounted on the counterweight frame 4, the projections of the first roller 1 and the second roller 2 in the horizontal direction correspond to the thickness direction of the counterweight frame 4, and the two through-holes 33 are also arranged along the thickness direction of the counterweight frame 4. The adjusting bolts 34 pass through the through-holes 33 and the adjusting shims 35 in sequence and are connected to the bolt holes on the counterweight frame 4, that is, the adjusting shims 35 are disposed between the counterweight frame 4 and the connecting part 31. Therefore, the setting part of the adjusting bolts 34 can not only fix the mounting member 3 on the counterweight frame 4, but also change the angle at which the mounting member 3 is mounted on the counterweight frame 4 by adjusting the number of adjusting shims 35 corresponding to the two through-holes 33, thereby adjusting the size of the included angle A to accommodate C-shaped guide rails 5 of different widths.

[0050] In addition, during installation, when the rollers in the prior art are installed in the guide grooves of the guide rails or disassembled from the guide grooves of the guide rails, especially for T-shaped guide grooves and C-shaped guide grooves. It is necessary to move the counterweight frame 4 to the bottom or the top of the C-shaped guide rail 5, which undoubtedly increases the difficulty and complexity of replacing and repairing the guide shoes. When the counterweight guiding device in the present application is installed on the C-shaped guide rail 5, it can be installed at any position on the C-shaped guide rail 5. The specific operation is as follows. First, rotate the mounting member 3 on which the first roller 1 and the second roller 2 are installed by an angle. The rotation angle makes the included angle between the connection line of the axes of the first roller 1 and the second roller 2 and the horizontal plane increase, that is, the included angle A increases, so that the projection of the connection line between the first roller 1 and the second roller 2 in the horizontal direction is shortened. Then, smoothly place the first roller 1 and the second roller 2 into the C-shaped guide rail 5. After that, rotate the mounting member 3 to make the included angle between the connection line of the axes of the first roller 1 and the second roller 2 and the horizontal plane decrease, that is, the included angle A decreases, so that the projection of the connection line between the axes of the first roller 1 and the second roller 2 in the horizontal direction is lengthened, so that the first roller 1 and the second roller 2 can respectively abut against both sides of the C-shaped guide rail 5. Then, install the mounting member 3 on the counterweight frame 4 through the adjustment bolt 34 and the adjustment gasket 35. During disassembly, the steps are opposite to the above. Just rotate the angle of the mounting member 3 to shorten the projection of the connection line of the axes of the first roller 1 and the second roller 2 in the horizontal direction, and then the first roller 1 and the second roller 2 can be taken out from the guide groove. Therefore, the counterweight guiding device in this embodiment can be replaced and installed at any position of the C-shaped guide rail 5, and has the characteristics of convenient replacement and installation.

[0051] In one embodiment, the mounting member 3 is an L-shaped mounting plate. The connecting portion 31 is a horizontal connecting plate provided on the L-shaped mounting plate, and the mounting portion 32 is a vertical mounting plate provided on the L-shaped mounting plate. A reinforcing rib plate 36 for improving the overall strength is provided between the horizontal connecting plate and the vertical connecting plate. The vertical mounting plate, the horizontal connecting plate and the reinforcing rib plate 36 are combined to form an integral structure.

[0052] In one embodiment, 30° < A < 60°. Within this range of the included angle A, the movements of the first roller 1 and the second roller 2 can respectively fit with both sides of the C-shaped guide rail 5. Compared with other angles, a more stable operating state can be achieved. In this embodiment, the included angle A is set to 45°.

[0053] The elevator counterweight guiding device in this embodiment consists of at least two rollers, namely a first roller 1 and a second roller 2. When the first roller 1 and the second roller 2 are installed, the angle between the line connecting their axes and the horizontal plane is an acute angle. This means that the first roller 1 and the second roller 2 are not on the same horizontal plane when sliding along the C-shaped guide rail 5. This ensures that when the counterweight guiding device is installed on the counterweight frame 4, if the counterweight frame 4 tilts, although one roller may lose contact with the C-shaped guide rail 5, the other roller will still maintain sliding contact with it. This allows the counterweight frame 4 to continue sliding along the C-shaped guide rail 5, effectively avoiding the adverse effects on the rollers caused by the tilting or offset of the counterweight frame 4, thereby reducing roller friction and increasing roller lifespan. Furthermore, when the first roller 1 and the second roller 2 run within the C-shaped guide rail 5, the first roller 1 and the second roller 2 are at different running heights. That is, the positions where the first roller 1 and the second roller 2 contact the C-shaped guide rail 5 are also at different heights. In other words, the positions where the first roller 1 and the second roller 2 generate sound on the guide rail are also different. This can prevent the first roller 1 and the second roller 2 within the C-shaped guide rail 5 from resonating, thereby reducing noise. Compared with the prior art, it has a low noise and vibration effect.

[0054] In addition, when installing the elevator counterweight guide device, firstly, rotate the mounting piece 3, which has the first roller 1 and the second roller 2 installed, by an angle. This rotation increases the angle between the line connecting the axes of the first roller 1 and the second roller 2 and the horizontal plane, thus increasing angle A. This shortens the horizontal projection of the line connecting the first roller 1 and the second roller 2. Then, smoothly place the first roller 1 and the second roller 2 into the C-shaped guide rail 5. Next, rotate the mounting piece 3 to decrease the angle between the line connecting the axes of the first roller 1 and the second roller 2 and the horizontal plane, thus decreasing angle A. This lengthens the horizontal projection of the line connecting the first roller 1 and the second roller 2, allowing the first roller 1 and the second roller 2 to abut against both sides of the C-shaped guide rail 5. Finally, install the mounting piece 3 onto the counterweight frame 4 using adjusting bolts 34 and adjusting shims 35. Removal is performed by reversing the above steps. Therefore, the counterweight guide device in this embodiment can be replaced and installed at any position on the C-shaped guide rail 5, and has the characteristics of convenient replacement and installation.

[0055] Example 3: Reference Figures 1 to 6 As shown, a counterweight device includes a counterweight frame 4, a plurality of counterweight blocks 41 are disposed inside the counterweight frame 4, and an elevator counterweight guide device as described in Embodiment 1 or Embodiment 2.

[0056] The elevator counterweight guide devices are installed at the upper and lower ends of both sides of the counterweight frame 4 in the width direction. That is, there are two elevator counterweight guide devices on each side of the counterweight frame 4 in the width direction, and the two elevator counterweight guide devices on each side are respectively installed at the upper and lower ends of the counterweight frame 4.

[0057] In one embodiment, mounting bolt holes are provided on both the upper and lower end faces of the counterweight frame 4. A pair of mounting bolt holes are provided at each end of the length direction of the upper and lower end faces, and each pair of mounting bolt holes is arranged along the thickness direction of the counterweight frame 4. Each pair of mounting bolt holes corresponds to the position of the through portion 33. When the mounting component 3 is installed on the counterweight frame 4, the adjusting bolt 34 is sequentially passed through the through portion 33, the adjusting shim 35, and the mounting bolt holes for fixed connection, thereby fixing the elevator counterweight guide device on the counterweight frame 4.

[0058] The counterweight device also includes C-shaped guide rails 5 vertically arranged at both ends of the counterweight frame 4 in the width direction. The C-shaped guide rails 5 have guide grooves 51 that cooperate with the first roller 1 and the second roller 2. When the counterweight frame 4 slides along the C-shaped guide rails 5, the first roller 1 and the second roller 2 abut against the side walls on both sides of the guide groove 51. The guide groove 51 has a certain limiting function, making the movement of the first roller 1 and the second roller 2 along the guide groove 51 more stable, thereby making the entire counterweight frame 4 more stable and reducing the vibration generated during operation.

[0059] The working principle of this embodiment is as follows: (1) Install the elevator counterweight guide device. First, rotate the mounting part 3 with the first roller 1 and the second roller 2 installed at an angle. The angle of rotation increases the angle between the line connecting the axes of the first roller 1 and the second roller 2 and the horizontal plane, so that the angle A increases, thereby shortening the projection of the line connecting the first roller 1 and the second roller 2 in the horizontal direction; then smoothly place the first roller 1 and the second roller 2 into the guide groove 51; (2) Rotate the mounting part 3 to decrease the angle between the line connecting the axes of the first roller 1 and the second roller 2 and the horizontal plane, so that the angle A decreases, thereby lengthening the projection of the line connecting the first roller 1 and the second roller 2 in the horizontal direction, so that the first roller 1 and the second roller 2 can respectively abut against the two sides of the guide groove 51. Then, install the mounting part 3 on the counterweight frame 4 with the cooperation of the adjusting bolt 34 and the adjusting shim 35; (3) The elevator counterweight guide device is removed in the opposite way to the above installation steps. Therefore, the counterweight guide device in this embodiment can be replaced and installed at any position on the C-shaped guide rail 5, and has the characteristics of convenient replacement and installation.

[0060] Example 4: Reference Figure 7As shown, this embodiment is similar in structure to Embodiment 2 or Embodiment 3. The mounting assembly can also be configured as follows: an adjustment groove 37 is fixedly mounted on the mounting part 32, the adjustment groove 37 is set along the thickness direction of the counterweight frame 4, the shaft of the second roller 2 is slidably mounted in the adjustment groove, a positioning block 38 is provided on the mounting part 3, the positioning block is threadedly connected to a positioning bolt, and the positioning bolt 39 passes through the positioning block, with the end of the positioning bolt 39 abutting against the nut of the shaft on the second roller. Locking nuts are provided on both sides of the positioning bolt 39 on the positioning block. By adjusting the length of the positioning bolt, the position of the second roller 2 is adjusted, thereby adjusting the size of the angle A between the line 1 connecting the second roller 2 and the first roller and the horizontal plane. Similarly, the adjustment groove 37, positioning block 38, and positioning bolt 39 can also be provided at the position corresponding to the first roller 1 to adjust the position of the first roller 1, thereby adjusting the size of A.

[0061] Example 5: Figure 5 As shown, this embodiment is similar in structure to embodiment 3, except that when the mounting part 3 is installed on the counterweight frame 4, the distance between the end face of the mounting part 32 facing the C-shaped guide rail 5 and the bottom end face of the C-shaped guide rail 5 is H, and the depth of the C-shaped guide rail 5 is h, where H>h.

[0062] In this application, the above-mentioned limiting structure creates a distance between the mounting part and the bottom end face of the guide rail, making the distance between the mounting part and the bottom end of the guide rail greater than the depth of the guide rail. This allows the mounting part to be located outside the guide rail, ensuring that when any mounting part is rotated at any angle, the mounting part remains outside the guide groove 51 and is not stuck by the guide groove 51.

[0063] Example 6: A method for installing a counterweight device, comprising the counterweight device as described in Example 3, and further comprising the following steps:

[0064] Step 1: Rotate the elevator counterweight guide device to reduce the length of the horizontal projection of the line connecting the axes of the first roller 1 and the second roller 2, and place the first roller 1 and the second roller 2 into the C-shaped guide rail 5.

[0065] Step 2: Rotate the elevator counterweight guide device to increase the length of the horizontal projection of the line connecting the axes of the first roller 1 and the second roller 2, so that the first roller 1 and the second roller 2 abut against the side walls on both sides of the C-shaped guide rail 5 respectively.

[0066] Step 3: Securely install the elevator counterweight guide device onto the counterweight frame 4. Pass the adjusting bolt 34 sequentially through the through-hole 33, the adjusting shim 35, and the mounting bolt hole to secure it, thus fixing the mounting component 3 onto the counterweight frame 4.

[0067] Step 4, observe whether the first roller 1 and the second roller 2 are respectively abutted against both sides of the C-shaped guide rail 5. If the first roller 1 and the second roller 2 are not abutted against both sides of the C-shaped guide rail 5, adjust the number of adjusting shims 35 to incline the mounting member 3, so that the projection of the line connecting the centers of the first roller 1 and the second roller 2 in the horizontal direction increases, and make the first roller 1 and the second roller 2 respectively abut against both sides of the C-shaped guide rail 5.

[0068] Step 5, repeat the above steps 1 to 4 to install the elevator counterweight guiding device at the upper and lower ends on both sides in the width direction of the counterweight frame 4.

[0069] When the rollers in the prior art are installed or disassembled, the counterweight frame 4 needs to be moved to the bottommost or topmost end of the C-shaped guide rail 5, which undoubtedly increases the difficulty and complexity of replacing and repairing the guide shoes. In this embodiment, by the above method, the mounting member 3 with the first roller 1 and the second roller 2 installed is rotated by an angle, and the rotation angle is such that the included angle between the line connecting the centers of the first roller 1 and the second roller 2 and the horizontal plane increases, that is, the included angle A increases, so that the projection of the line connecting the first roller 1 and the second roller 2 in the horizontal direction is shortened. Then, the first roller 1 and the second roller 2 are smoothly placed in the C-shaped guide rail 5. After that, the mounting member 3 is rotated so that the included angle between the line connecting the centers of the first roller 1 and the second roller 2 and the horizontal plane decreases, that is, the included angle A decreases, and the projection of the line connecting the first roller 1 and the second roller 2 in the horizontal direction is lengthened, so that the first roller 1 and the second roller 2 can respectively abut against both sides of the C-shaped guide rail 5. Then, the mounting member 3 is installed on the counterweight frame 4 through the cooperation of the adjusting bolts 34 and the adjusting shims 35. The disassembly is the reverse of the above steps. Therefore, through the above installation method, the counterweight guiding device can be replaced and installed at any position of the C-shaped guide rail 5, and has the characteristics of convenient replacement and installation.

[0070] Embodiment 7: An elevator counterweight device, the core of which lies in the unique configuration of the first roller 1 and the second roller 2 and the design of the included angle A (0° < A < 90°) between the line connecting the centers of the two rollers and the horizontal plane, aiming to improve the running stability and installation convenience of the elevator counterweight frame on the guide rail. To improve the inconvenience of the traditional roller installation method, this embodiment introduces a mounting member 3 as an auxiliary. Different from directly fixing the rollers on both sides of the counterweight frame, this design realizes the installation of the rollers through the mounting member 3. The mounting member 3 skillfully integrates a connecting part 31 and a mounting part 32. The former is arranged in the horizontal direction for firm connection with the counterweight frame 4; the latter is arranged in the vertical direction for carrying and fixing the first roller 1 and the second roller 2, ensuring that the rollers can be installed on the counterweight frame together with the mounting member, simplifying the installation process.

[0071] In view of the differences in the widths of different guide rails, an angle adjustment mechanism is further integrated in this embodiment. This mechanism indirectly adjusts the size of the angle A between the axis connection line of the first roller 1 and the second roller 2 and the horizontal plane by adjusting the angle of the mounting member 3. Specifically, the mounting component includes a through portion 33, an adjusting bolt 34, and an adjusting gasket 35. By increasing or decreasing the number of adjusting gaskets, the mounting angle of the mounting member on the counterweight frame can be flexibly adjusted, thereby achieving the tight fit of the rollers to the side walls on both sides of the guide rail and enhancing the stability of the counterweight frame.

[0072] Another highlight of the design lies in the convenience of its installation and disassembly. Compared with the traditional method that requires moving the counterweight frame to the extreme position of the guide rail, this device allows installation or disassembly at any position on the guide rail. During operation, only need to rotate the mounting member to increase the angle A between the axis connection line of the rollers and the horizontal plane, shorten the projection of the roller connection line in the horizontal direction, and easily place the rollers into the guide rail; then rotate the mounting member in the reverse direction to reduce the angle A, make the rollers closely adhere to both sides of the guide rail, and finally complete the fixation through the adjusting bolt and gasket. The disassembly process is the opposite, greatly improving the maintenance efficiency and convenience.

[0073] As the elevator system starts, the elevator counterweight device begins to play its key role in ensuring the balance and stability between the elevator car and the counterweight frame. First, when the elevator starts to run, the first roller 1 and the second roller 2 roll smoothly along both sides of the C-shaped guide rail 5. Since a carefully designed angle A (0° < A < 90°) is maintained between the axis connection line of the two rollers and the horizontal plane, this design not only enhances the contact area between the rollers and the guide rail, but also provides additional stability, effectively reducing vibration and noise. The rolling track of the rollers on the guide rail is smooth and continuous, ensuring the smooth movement of the elevator counterweight frame 4.

[0074] As the running direction of the elevator changes, the counterweight device can quickly respond and adapt to the curvature change of the guide rail through the flexible support of the mounting member 3. The connecting portion 31 of the mounting member 3 is firmly connected to the counterweight frame, ensuring the stability of the entire device in the vertical direction; while the mounting portion 32 cleverly carries the rollers, enabling them to roll freely along the track of the guide rail. This design makes the rollers hardly generate any lateral offset during the rolling process, further enhancing the smoothness of operation.

[0075] When it is necessary to adjust the tightness of the contact between the rollers and the guide rail, the angle adjustment mechanism on the mounting member 3 plays a key role. By simply increasing or decreasing the number of adjusting gaskets 35 and tightening the adjusting bolt 34, the operator can easily adjust the inclination angle of the mounting member 3, thereby changing the angle A between the axis connection line of the rollers and the horizontal plane. This adjustment process is rapid and precise, ensuring that the rollers can closely adhere to the side walls on both sides of the guide rail, thus improving the stability of the counterweight frame on the guide rail.

[0076] Example 8: An elevator counterweight guide device. In a specific configuration of this example, the mounting component 3 adopts an L-shaped structure design, wherein the horizontal connecting plate serves as the connecting part 31 and is stably placed on the horizontal section of the L-shaped plate; while the vertical mounting plate plays the role of the mounting part 32 and is vertically set on the vertical section of the L-shaped plate. To enhance the stability of the overall structure, a reinforcing rib 36 is cleverly added between the horizontal connecting plate and the vertical mounting plate, and the three fit together tightly to form a sturdy and compact whole.

[0077] Through careful calculation and experimental verification, this embodiment limits the included angle A to between 30° and 60° to ensure that the first roller 1 and the second roller 2 operate optimally on the C-shaped guide rail 5. In particular, when the included angle A is set to 45°, the fit between the roller and the guide rail and the running stability are both optimal, effectively reducing the adverse effects caused by the tilt of the counterweight frame and extending the service life of the roller.

[0078] This elevator's counterweight guiding device innovatively adopts a non-coplanar roller layout, meaning that the first roller 1 and the second roller 2 run at different heights on the C-shaped guide rail 5, thereby avoiding resonance between the rollers and significantly reducing operating noise. Furthermore, this design enhances the stability of the counterweight frame 4 in tilted states; even if one roller temporarily detaches from the guide rail, the other roller maintains effective contact, ensuring smooth sliding of the counterweight frame.

[0079] During installation, the user can first adjust the angle of mounting component 3 to increase the angle A between the line connecting the roller axes and the horizontal plane, thereby shortening the projection of the roller line in the horizontal direction, making it easier to place the roller into the guide rail. Then, the angle of the mounting component is adjusted in the opposite direction to ensure the roller fits snugly against both sides of the guide rail, and it is then securely installed on the counterweight frame 4 using the combination of adjusting bolts 34 and adjusting shims 35. Disassembly is the reverse process, equally simple and quick, without requiring the counterweight frame to be moved to the extreme positions of the guide rail.

[0080] The upper and lower end faces of the counterweight frame 4 are provided with mounting bolt holes corresponding to the through-parts 33 of the mounting component 3, facilitating stable installation through the combination of adjusting bolts 34 and adjusting shims 35. Each pair of mounting bolt holes is arranged along the thickness direction of the counterweight frame to ensure a tight connection between the mounting component and the counterweight frame. The C-shaped guide rail 5 is arranged along the width direction of the counterweight frame 4 and is equipped with a guide groove 51 inside, which fits tightly with the first roller 1 and the second roller 2. The design of the C-shaped guide groove not only enhances the guiding stability of the rollers but also reduces vibration during operation, improving the overall smoothness of operation.

[0081] During operation, the L-shaped mounting piece firmly supports the first roller and the second roller to slide smoothly within the C-shaped guide groove of the guide rail. The non-coplanar layout between the rollers effectively avoids resonance and reduces noise. The mounting piece is strengthened by rib plates to enhance its stability, ensuring that the rollers closely adhere to both sides of the guide rail at an optimal angle (30° - 60°, with the optimal being 45°). Even in an inclined state, the rollers can maintain effective contact, ensuring smooth sliding of the counterweight frame. The installation and disassembly process is simple and quick, without the need to move the counterweight frame to extreme positions, and can be completed by adjusting the angle of the mounting piece and tightening the bolts. The overall design improves the stability and reliability of elevator operation.

[0082] Embodiment 9: An elevator counterweight guiding device. In this embodiment, through an innovative roller configuration and a flexible installation adjustment mechanism, the stability and efficiency of the elevator counterweight frame running on the guide rail are improved. The device consists of a differential height roller system, which includes two main rollers, the first roller 1 and the second roller 2, configured at different heights. High-quality bearings are equipped inside each roller to ensure smooth rolling and low noise. At the same time, a sealing device is provided outside the roller to prevent dust and impurities from entering, extending the service life of the roller.

[0083] As the core components of the device, these two rollers are precisely installed at different vertical heights. By adjusting their relative positions, the connecting line of their axles forms an acute angle A (0° < A < 90°) with the horizontal plane. This design ensures that in an inclined state of the counterweight frame, at least one roller can continuously maintain effective contact with the guide rail, thus preventing roller jamming and reducing wear caused by friction.

[0084] To simplify the installation process and improve the overall structural stability, an integrated mounting bracket is introduced. The bracket integrates roller mounting seats and interfaces for connecting to the counterweight frame. During installation, simply fix the integrated mounting bracket to the counterweight frame, and then install the first roller 1 and the second roller 2 onto the corresponding roller mounting seats. Special roller mounting seats are provided on the integrated mounting bracket, and these mounting seats are precisely machined to ensure that the rollers can be firmly and accurately installed. The mounting seats are also equipped with adjustable fixing devices to facilitate fine-tuning according to the size of the rollers.

[0085] Considering the width differences of different elevator guide rails, an angle adaptive adjustment module is set up, allowing users to flexibly adjust the inclination angle of the integrated mounting bracket according to the actual width of the guide rail, thereby changing the angle A between the connecting line of the axles of the first roller 1 and the second roller 2 and the horizontal plane. This design ensures that the rollers can closely adhere to both sides of the guide rail, improving the stability and safety of operation.

[0086] The differentiated height roller system effectively solves the counterweight tilting problem, ensuring the elevator's stability during operation. The integrated mounting bracket design simplifies and speeds up roller installation, reducing costs and time. The angle adaptive adjustment module allows the device to adapt to different guide rail specifications, improving its versatility and flexibility. Because the rollers contact the guide rail at varying heights, resonance is avoided, thus reducing elevator noise levels during operation.

[0087] As the elevator starts moving, the differentiated height roller system in the elevator counterweight guide mechanism begins to demonstrate its unique advantages. The first and second rollers, located at different vertical heights, roll smoothly along the guide rails, supported by high-quality bearings. Thanks to the external sealing devices on the rollers, dust and impurities are effectively prevented from entering, ensuring smooth and durable rolling. During elevator operation, the counterweight frame may tilt slightly due to various factors. However, thanks to the non-coplanar configuration of the rollers, even when tilted, at least one roller maintains continuous effective contact with the guide rail, thus avoiding roller jamming and unnecessary wear. This design significantly improves the stability and safety of elevator operation.

[0088] The integrated mounting bracket, as the core structure of the device, firmly connects the rollers and the counterweight frame. The roller mounting seats on it are precisely machined to ensure accurate positioning and secure installation of the rollers. When the elevator is running, the rollers, supported by the mounting seats, roll freely along the guide rails, providing stable guidance for the counterweight frame. The presence of an angle adaptive adjustment module allows the device to easily handle guide rails of varying widths. Users simply need to adjust the tilt angle of the integrated mounting bracket according to the actual width of the guide rail to change the angle A between the line connecting the roller axes and the horizontal plane, ensuring a tight fit between the rollers and both sides of the guide rail. This flexible adjustment mechanism not only improves the versatility and flexibility of the device but also further enhances the stability and safety of elevator operation.

[0089] Example 10: A method for installing a counterweight device, which further improves and describes the method of Example 5.

[0090] Step 1: Roller Pre-positioning. First, ensure all mounting components (including first roller 1, second roller 2, mounting bracket 3, adjusting bolt 34, adjusting shim 35, etc.) are complete and undamaged, and prepare the installation tools. Gently rotate the elevator counterweight guide device. By rotating mounting bracket 3, the angle A between the line connecting the axes of first roller 1 and second roller 2 and the horizontal plane increases. This operation shortens the projected length of the roller axis connection line in the horizontal direction, creating space for the rollers to smoothly enter the C-shaped guide rail 5. After confirming the angle adjustment is in place, align first roller 1 and second roller 2 with the opening of the C-shaped guide rail 5 and gently push them in until the rollers are fully inside the guide rail.

[0091] Step Two: Roller Positioning Adjustment. After the rollers are installed on the rails, rotate the elevator counterweight guide device in the reverse direction, gradually reducing the angle A between the line connecting the roller axes and the horizontal plane, thus increasing the projected length of the line connecting the roller axes in the horizontal direction. By continuously fine-tuning the rotation angle, ensure that the first roller 1 and the second roller 2 are tightly against the two side walls of the C-shaped guide rail 5, achieving precise positioning. At this point, the rollers should be able to slide stably along both sides of the guide rail without any shaking or deviation. After the rollers are accurately positioned, initially tighten the adjusting bolts 34 to maintain a certain connection force between the mounting component 3 and the counterweight frame 4, but do not tighten them completely.

[0092] Step 3: Secure Installation. Using adjusting bolts 34, pass them through the through-hole 33 of mounting component 3, then through the adjusting shims 35 and the mounting bolt holes, and finally tighten the bolts completely to securely install the elevator counterweight guide device onto the counterweight frame 4. After installation, carefully check the contact between the rollers and the guide rails. Ensure that the first roller 1 and the second roller 2 are tightly fitted to both sides of the guide rails without any gaps or misalignment. If a slight deviation is found between the rollers and the guide rails, the tilt of mounting component 3 can be fine-tuned by increasing or decreasing the number of adjusting shims 35 to further optimize the contact between the rollers and the guide rails.

[0093] Step 4: Calibration and Fine-tuning. After installation, check the contact between the rollers and the guide rail. If there is a deviation, adjust the tilt of the mounting piece 3 by increasing or decreasing the number of adjusting shims 35 until the rollers are fully in contact with both sides of the guide rail to ensure smooth operation.

[0094] Step 5: Full Installation. Following the methods described in Steps 1 to 3 above, install the elevator counterweight guide devices at both the top and bottom ends of the counterweight frame 4 in the width direction. Ensure that each roller undergoes precise pre-positioning, positioning adjustment, and fixing. After all rollers are installed, perform a comprehensive verification of the entire counterweight device. Check whether the rollers slide smoothly and steadily on the guide rails, and whether there are any abnormal noises or vibrations. Simultaneously, confirm whether the counterweight frame 4 remains horizontal and stable during movement.

[0095] This embodiment introduces an angle adjustment mechanism, allowing for flexible adjustment of the relative position between the roller and the mounting component. During installation, operators no longer need to laboriously move the heavy counterweight frame; simply rotating the mounting component allows the roller to smoothly enter the guide rail and be precisely positioned. This "on-site installation" method greatly simplifies the installation steps, shortens the installation cycle, and reduces labor intensity. When the roller needs to be replaced or repaired, there is also no need to move the counterweight frame to a specific position. Simply following the reverse operation procedure allows for easy removal and replacement of the roller. This convenience not only improves maintenance efficiency but also reduces the impact of prolonged downtime on elevator operation, providing users with a superior service experience.

[0096] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
