Description

Technical Field

[0001] This invention relates to the field of elevator installation technology, and more specifically, to an installation structure for elevator slide rails. 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, with a cross-sectional shape of T-shape. While playing a guiding role, the guide rails also bear the impact force when the car and elevator brake, as well as the impact force when the safety brake brakes in an emergency.

[0003] During the installation of elevator slide rails, multiple slide rails need to be connected end to end, and adjacent slide rails must be aligned during installation to ensure the smoothness between the outer surfaces of adjacent slide rails (i.e., to ensure the connection accuracy of the slide rails). The connection accuracy of hollow slide rails and escalator slide rails is guaranteed by the end dimensions and geometric tolerances of the slide rails. The connection accuracy of the slide rails directly affects the smoothness and comfort of elevator operation. Any bending or twisting at any point on the slide rail will give the car a lateral force, affecting the linear motion of the car up and down, causing the car to sway. As the elevator speed increases, the car will vibrate, thus affecting comfort.

[0004] In the process of connecting hollow slide rails, the existing elevator slide rail installation structure is usually fixed to the slide rail frame by applying pressure plates. The pressure plates (i.e., the slide rail pressure plates in this invention) act on both sides of the hollow slide rail. However, this installation method cannot support the inner wall of the middle of the hollow slide rail, and the alignment of the middle of the hollow slide rail is not convenient.

[0005] For example, the "hollow elevator guide rail" disclosed in Chinese invention patent (application number: 200910030171.8) is described as including a guide rail base and a hollow guide rail body connected to the guide rail base. The guide rail body includes a pair of parallel guide rail edges and a guide edge connecting the pair of guide rail edges. The cross-section of the hollow elevator guide rail forms a "convex" shaped sealed hollow structure. This sealed hollow structure not only enhances its resistance to torsional deformation in the length direction, but also allows for series connection through internal connection, greatly facilitating the installation of the entire elevator guide rail, ensuring the straightness of the entire elevator guide rail, and reducing elevator operating noise. The above patent can corroborate the defects of the prior art.

[0006] Therefore, we made improvements and proposed an installation structure for elevator slide rails. Summary of the Invention

[0007] The purpose of this invention is to address the problem of inconvenient alignment in the middle of existing hollow slide rails.

[0008] To achieve the above-mentioned objectives, the present invention provides an elevator slide rail mounting structure to improve the aforementioned problems.

[0009] The application is as follows:

[0010] It includes a first hollow slide rail, a second hollow slide rail, an extension plate, and a slide rail pressure plate. The side of the extension plate and the slide rail pressure plate together press the connection between the first hollow slide rail and the second hollow slide rail. The other end of the extension plate is provided with a connecting steel plate, which is fixedly installed on the wall of the elevator shaft.

[0011] It also includes a support mechanism, the top view projection shape of which is the same as the inner wall contour of the first hollow slide rail. The support mechanism is detachably installed at the junction of the first and second hollow slide rails and is used to support the interior of the first and second hollow slide rails.

[0012] As a preferred technical solution of this application, the support mechanism includes a support frame and support plates located on both sides of the support frame. The support frame has a cylindrical structure in the middle, and support plates are provided at both ends of the cylindrical structure. The support plates are provided with a rotating support mechanism for driving the two support plates away from each other. The rotating support mechanism drives the support plates on both sides away from each other, so that the support plates are pressed into the interior of the first hollow slide rail and the second hollow slide rail.

[0013] As a preferred technical solution of this application, the rotating support mechanism includes a rotating column rotatably mounted on a support plate. The end of the rotating column away from the support plate is connected to the side of the support plate through a rocker arm. A torsion spring for driving the rocker arm to rotate is sleeved on the outer side of the rotating column.

[0014] As a preferred technical solution of this application, the two sets of rotating support mechanisms are symmetrically arranged on the inner wall of the support plate, and each set of rotating support mechanisms drives each support plate to rotate; an adjustment mechanism for fixing the rotating support mechanisms is provided between the two sets of rotating support mechanisms.

[0015] As a preferred technical solution of this application, the adjustment mechanism includes a mounting cylinder fixedly installed on the support plate. A threaded rod is threadedly installed inside the mounting cylinder. A connecting block is rotatably provided at one end of the threaded rod that extends into the support plate. A locking block is provided on the rocker arm. The locking block is connected to the connecting block through an adjusting rod. The two ends of the adjusting rod are rotatably connected to the locking block and the connecting block, respectively.

[0016] As a preferred technical solution of this application, one side of the card block is connected to the rocker arm, the card block is provided with a card slot, and the end of the adjusting rod is provided with a locking rod for locking into the inner wall of the card slot, the locking rod being slidably installed inside the card slot.

[0017] As a preferred technical solution of this application, a straightness detection mechanism is provided on the end faces of the two support plates facing each other. The straightness detection mechanism includes a mounting plate installed on the support plate, a slide rod fixedly installed on the mounting plate, a roller slidably installed on the side of the slide rod, and an elastic element on the slide rod that drives the roller away from the mounting plate. The straightness of the connection between the first hollow slide rail and the second hollow slide rail is determined according to the position of the roller on the slide rod.

[0018] As a preferred technical solution of this application, the mounting plate is provided with an electrical connection piece, which is located between the mounting plate and the roller. When the roller is stuck on both sides of the first hollow slide rail or the second hollow slide rail, the electrical connection piece contacts the side of the roller to connect the detection circuit.

[0019] As a preferred technical solution of this application, the roller is slidably connected to the slide rod through the connecting column, and the roller is rotatably connected to the connecting column. A connecting wire is provided inside the connecting column. One end of the connecting wire is provided with a wire connection end. The other end of the connecting wire passes through the middle of the connecting column and is connected to an electrical connection plate provided on the side of the roller. When the electrical connection plate contacts the electrical connection piece, the detection circuit is turned on.

[0020] As a preferred technical solution of this application, the support plate is provided with multiple indicator lights, which are set in each detection circuit. When the detection circuit is turned on, the indicator lights are lit.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In the scheme of this application:

[0023] 1. To address the problem in existing technologies where elevator slide rails are typically fixed to the slide rail frame using pressure plates during the docking process, with the pressure plates (i.e., the slide rail pressure plates in this invention) acting on both sides of the hollow slide rail, this installation method cannot support the inner wall of the hollow slide rail in the middle, making alignment of the middle of the hollow slide rail inconvenient. This application addresses this issue by providing a support mechanism that, when two hollow slide rails are docked, supports the inner sides of both hollow slide rails, simultaneously aligning the front-to-back position and the action position of the first hollow slide rail with the second hollow slide rail below, eliminating the need for installers to repeatedly adjust the position of the first hollow slide rail for alignment.

[0024] 2. To solve the problem that the support mechanism in the prior art cannot be easily fixed inside the first hollow slide rail or the second hollow slide rail, this application sets up a rotating support mechanism. The rotating support mechanism drives the two support plates set opposite each other on the support mechanism to move away from each other, so that the support plates can press against the inner wall of the first hollow slide rail or the second hollow slide rail on both sides respectively, and fix the support mechanism as a whole inside the first hollow slide rail or the second hollow slide rail, without the need for elevator slide rail installers to manually support it;

[0025] 3. By setting an adjustment mechanism, it is possible to easily fold the two opposing support plates to the sides of the support frame when the support mechanism is not in use, thereby reducing the size of the support mechanism and solving the problem of storing or retrieving the support mechanism when it is not in use.

[0026] 4. By using a flatness detection mechanism installed on the inner wall of the support plate, the flatness of the raised surface in the middle of the first hollow slide rail or the second hollow slide rail can be determined based on whether the positions of the upper and lower sets of rollers on the slide rod are consistent. This solves the problem that the flatness of the connection between the first hollow slide rail and the second hollow slide rail cannot be conveniently detected in the prior art.

[0027] 5. By setting a connecting wire inside the connecting column, with one end of the connecting wire connected to the electrical connecting plate, the electrical connecting plate will not rotate when the roller rotates. This solves the problem of wear at the contact point between the electrical connecting plate and the electrical connecting piece when the roller rotates, which prevents the electrical connecting piece and the electrical connecting plate from being used for a long time.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] As described in the background art, the existing elevator slide rail installation structure is usually fixed to the slide rail frame by applying pressure plates. The pressure plates act on both sides of the hollow slide rail. However, this installation method cannot support the inner wall of the hollow slide rail in the middle, and the alignment of the middle of the hollow slide rail is not convenient.

[0040] To solve this technical problem, the present invention provides an elevator slide rail installation structure, which is applied in the installation process of hollow slide rails.

[0041] For details, please refer to Figure 1 and Figure 2 The elevator slide rail installation structure specifically includes:

[0042] It includes a first hollow slide rail 1, a second hollow slide rail 2, an extension plate 3 and a slide rail pressure plate 5. The side of the extension plate 3 and the slide rail pressure plate 5 together press the connection between the first hollow slide rail 1 and the second hollow slide rail 2. The other end of the extension plate 3 is provided with a connecting steel plate 4, which is fixedly installed on the wall of the elevator shaft.

[0043] It also includes a support mechanism 6, the top view projection shape of which is the same as the inner wall contour of the first hollow slide rail 1. The support mechanism 6 is detachably installed at the junction of the first hollow slide rail 1 and the second hollow slide rail 2. The support mechanism 6 is used to support the inside of the first hollow slide rail 1 and the second hollow slide rail 2.

[0044] The elevator slide rail installation structure provided by this invention allows the support mechanism 6 to be supported at the joint of the first hollow slide rail 1 and the second hollow slide rail 2 during the installation process. After the support mechanism 6 is secured below the second hollow slide rail 2, the first hollow slide rail 1 is lifted and its lower end is inserted between the support mechanism 6 and the slide rail clamp 5. This simultaneously aligns the front-to-back position and the working position of the first hollow slide rail 1 with the second hollow slide rail 2 below, eliminating the need for installers to repeatedly adjust the position of the first hollow slide rail 1 for alignment. Furthermore, since the support mechanism 6 is supported inside the first hollow slide rail 1 and the second hollow slide rail 2, it increases the internal support strength of the first hollow slide rail 1 and the second hollow slide rail 2, allowing for more stable resistance to the force from the bridge box during elevator braking.

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] Example 1

[0049] Please refer to Figure 3 and Figure 4 The elevator slide rail installation structure includes a support mechanism 6 comprising a support frame 61 and support plates 62 located on both sides of the support frame 61. The support frame 61 has a cylindrical structure in the middle, and support plates 611 are provided at both ends of the cylindrical structure. The support plates 611 are provided with a rotating support mechanism 64 for driving the two support plates 62 away from each other. The rotating support mechanism 64 drives the support plates 62 on both sides away from each other, so that the support plates 62 are pressed into the interior of the first hollow slide rail 1 and the second hollow slide rail 2.

[0050] In this embodiment, since a rotating support mechanism 64 is provided on the support plate 611, the rotating support mechanism 64 can drive the two opposing support plates 62 to move away from each other when in use. When the support mechanism 6 is placed as a whole on the inner wall of the first hollow slide rail 1 or the second hollow slide rail 2, the support plates 62 can press against the inner walls of the first hollow slide rail 1 or the second hollow slide rail 2 on both sides respectively, fixing the support mechanism 6 as a whole inside the first hollow slide rail 1 or the second hollow slide rail 2, without requiring manual support from elevator slide rail installers.

[0051] Please refer to Figure 7 The elevator slide rail installation structure includes a rotating support mechanism 64, which includes a rotating column 641 rotatably mounted on a support plate 611. One end of the rotating column 641 away from the support plate 611 is connected to the side of the support plate 62 via a rocker arm 642. A torsion spring 643 for rotating the rocker arm 642 is sleeved on the outer side of the rotating column 641.

[0052] In addition, the torsion spring 643 on the rotating column 641 will drive the rocker arm 642 away from the rotating column 641 to rotate. At this time, the rocker arm 642 drives the two opposing support plates 62 to move away from each other. When the support mechanism 6 acts inside the first hollow slide rail 1 or the second hollow slide rail 2, the two support plates 62 can support the inner wall of the first hollow slide rail 1 or the second hollow slide rail 2, stabilizing the overall position of the support mechanism 6.

[0053] Example 2

[0054] The installation structure of the elevator slide rail provided in Example 1 is further optimized, specifically, as follows: Figure 7 As shown, two sets of rotating support mechanisms 64 are symmetrically arranged on the inner wall of the support plate 611. Each set of rotating support mechanisms 64 drives each support plate 62 to rotate. An adjustment mechanism 66 for fixing the rotating support mechanism 64 is provided between the two sets of rotating support mechanisms 64.

[0055] In this embodiment, by setting an adjustment mechanism 66, the position of the support mechanism 64 can be stably rotated during use. When the support mechanism 6 is not in use, the two opposing support plates 62 can be conveniently folded together to both sides of the support frame 61, thereby reducing the size of the support mechanism 6 and making it more convenient to store or retrieve.

[0056] Furthermore, such as Figure 7 and Figure 8 As shown, the adjustment mechanism 66 includes a mounting cylinder 662 fixedly mounted on a support plate 611. A threaded rod 661 is threadedly mounted inside the mounting cylinder 662. One end of the threaded rod 661, which extends into the support plate 611, is rotatably connected to a connecting block 6611. A locking block 6421 is provided on the rocker arm 642. The locking block 6421 is connected to the connecting block 6611 via an adjusting rod 663. Both ends of the adjusting rod 663 are rotatably connected to the locking block 6421 and the connecting block 6611, respectively. By setting the mounting cylinder 662 on the support plate 611 and threading the threaded rod 661 inside the mounting cylinder 662, the up-and-down movement of the threaded rod 661 drives the adjusting rod 663 to extend or retract, thereby achieving the effect of adjusting the position of the two rocker arms 642 that are set opposite to each other.

[0057] The locking block 6421 is connected to the rocker arm 642 on one side. The locking block 6421 is provided with a locking groove. The end of the adjusting rod 663 is provided with a locking rod for locking into the inner wall of the locking groove. The locking rod is slidably installed inside the locking groove. The mounting cylinder 662 is provided with a limiting post 6621 for limiting the adjusting rod 663 and preventing the adjusting rod 663 from rotating.

[0058] In addition, by setting a locking block 6421, the locking block 6421 and the adjusting rod 663 are detachably connected. During use, the locking rod can be easily slid out of the locking slot. At this time, the adjusting mechanism 66 and the rocker arm 642 are separated. The adjusting mechanism 66 is mainly used to stabilize the position of the rocker arm 642 and prevent the rocker arm 642 from rotating under the drive of the torsion spring 643, so that the support mechanism 6 is reduced in size during storage and transportation.

[0059] Example 3

[0060] The installation structure of the elevator slide rail provided in Embodiment 1 or 2 is further optimized, specifically, as follows: Figure 4 and Figure 5 As shown, each of the two support plates 62 has a straightness detection mechanism 63 on its mutually facing end faces. The straightness detection mechanism 63 includes a mounting plate 631 installed on the support plate 62, a slide rod 632 fixedly installed on the mounting plate 631, a roller 635 slidably installed on the side of the slide rod 632, and an elastic element 633 on the slide rod 632 that drives the roller 635 away from the mounting plate 631. The straightness of the connection between the first hollow slide rail 1 and the second hollow slide rail 2 is determined according to the position of the roller 635 on the slide rod 632.

[0061] In this embodiment, a flatness detection mechanism 63 is provided on the inner side of the support plate 62 to detect flatness when the support plate 62 is in a certain position. Figure 4 In the indicated state, the two support plates 62 can be clamped on both sides of the protrusion in the middle of the first hollow slide rail 1 or the second hollow slide rail 2. By driving the support frame 61 to move up and down, the rollers of the flatness detection mechanism 63 can slide on the surface of the protrusion in the middle of the first hollow slide rail 1 or the second hollow slide rail 2. The flatness of the surface of the protrusion in the middle of the first hollow slide rail 1 or the second hollow slide rail 2 can be judged by whether the positions of the upper and lower sets of rollers 635 on the slide rod 632 are consistent. The flatness of the first hollow slide rail 1 or the second hollow slide rail 2 is converted into the position difference of the rollers 635 on the slide rod 632. A device can be connected externally to determine the position of each roller 635 on its respective matching slide rod 632 to display the flatness at the junction of the first hollow slide rail 1 and the second hollow slide rail 2.

[0062] It should be noted that, in order to increase the support strength of the support frame 61, a support cylinder 67 is provided in the middle of the support frame 61, and the support cylinder 67 is welded to the support frame 61.

[0063] Furthermore, such as Figure 5 As shown, the mounting plate 631 is provided with an electrical connection piece 636, which is located between the mounting plate 631 and the roller 635. When the roller is stuck on both sides of the first hollow slide rail 1 or the second hollow slide rail 2, the electrical connection piece 636 contacts the side of the roller 635 to connect the detection circuit.

[0064] It should be noted that the side of the roller 635 is provided with conductive material. One end of the detection power supply is connected to the side of the roller, and the other end of the detection power supply is connected to the electrical connecting piece 636. When the roller 635 is squeezed and retracts, the circuit of the detection power supply is connected. When the roller 635 slides to the point where the difference between the outer surfaces of the first hollow slide rail 1 and the second hollow slide rail 2 is too large, the gap between one side of the roller 635 and the surface of the first hollow slide rail 1 or the second hollow slide rail 2 will increase. At this time, the side of the roller 635 will separate from the electrical connecting piece 636, and the detection circuit will be disconnected. The installer can easily determine that the flatness of the first hollow slide rail 1 and the second hollow slide rail 2 at this point is too large and the connection position of the first hollow slide rail 1 and the second hollow slide rail 2 needs to be adjusted.

[0065] Example 4

[0066] The installation structure of the elevator slide rail provided in the above embodiments is further optimized, such as... Figure 6 As shown, the roller 635 is slidably connected to the slide rod 632 via the connecting post 634, and the roller 635 is rotatably connected to the connecting post 634. The connecting post 634 is provided with a connecting wire 637 inside. One end of the connecting wire 637 is provided with a wire connection end 6371, and the other end of the connecting wire 637 passes through the middle of the connecting post 634 and is connected to the electrical connection plate 638 provided on the side of the roller 635. When the electrical connection plate 638 contacts the electrical connection piece 636, the detection circuit is turned on.

[0067] In this embodiment, by providing a connecting wire 637 inside the connecting post 634, with one end of the connecting wire 637 connected to the electrical connecting plate 638, the electrical connecting plate 638 will not rotate when the roller 635 rotates. This can prevent wear at the contact point between the electrical connecting plate 638 and the electrical connecting piece 636, allowing the electrical connecting piece 636 and the electrical connecting plate 638 to be used for a long time. In this embodiment, the roller 635 can be made of wear-resistant rubber.

[0068] Furthermore, such as Figure 4 and Figure 6 As shown, the support plate 611 is provided with a plurality of indicator lights 65, which are arranged in each detection circuit. When the detection circuit is turned on, the indicator lights 65 light up.

[0069] The indicator light 65 is connected to the detection circuit. When the detection circuit port is open, the elevator slide bar installer can observe it directly and determine whether the connection between the upper and lower hollow guide rails needs to be adjusted, which can improve the installation efficiency of the elevator slide bar.

[0070] The elevator slide rail installation structure provided by this invention is used as follows:

[0071] Working principle: When the first hollow slide rail 1 needs to be installed above the already fixed second hollow slide rail 2, first connect the protruding plate 3 and the connecting steel plate 4 to each other and install them on the inner wall of the elevator shaft. Then, install the slide rail clamp 5 on the top of the second hollow slide rail 2 at the lower end. Then, put the lower half of the support mechanism 6 into the interior of the second hollow slide rail 2. At this time, the two opposing support halves 62 on the support mechanism 6 tend to move away from each other under the action of the torsion spring 643, which can maintain the position of the support mechanism 6 inside the second hollow slide rail 2. Then, the first hollow slide rail 1 can be moved down along the support mechanism 6 so that the middle inner wall of the first hollow slide rail 1 is stuck on both sides of the support mechanism 6. When the lower end of the first hollow slide rail 1 is in close contact with the upper end of the second hollow slide rail 2, press the slide rail clamp 5 tightly at the connection between the first hollow slide rail 1 and the second hollow slide rail 2.

[0072] When it is necessary to test the straightness of the connection between the first hollow slide rail 1 and the second hollow slide rail 2, the support mechanism 6 is removed from inside the first hollow slide rail 1 and the second hollow slide rail 2. Then, driven by the torsion spring 643, the two opposing support plates 62 on the support mechanism 6 rotate to the position shown in the image. Figure 4 In the state shown, the two support plates 62 are then respectively clamped on both sides of the middle of the first hollow slide rail 1 and the second hollow slide rail 2. At this time, the support mechanism 6 can be moved up and down to detect the straightness of the connection between the first hollow slide rail 1 and the second hollow slide rail 2.
