Description

Technical Field

[0001] This utility model relates to a guide rail bracket, and more specifically, to an elevator guide rail bracket. Background Technology

[0002] Elevator guide rails provide a stable running track for the car and counterweight, ensuring their smooth vertical movement. This guiding function not only guarantees that the elevator moves along the predetermined path, avoiding the risk of deviating from the track or colliding, but also ensures safe operation by bearing some lateral forces during elevator operation. Therefore, the installation accuracy of elevator guide rails plays a crucial role in elevator safety. In some elevator shaft construction, the shaft walls may exhibit height deviations due to low construction precision. Consequently, during elevator guide rail installation, this can lead to deviations in the installation position accuracy of the car and counterweight, or necessitate temporary modifications or cutting of the guide rail supports and other structural dimensions, making standardized production impossible.

[0003] For example, Chinese Patent Publication No. CN205132815U, published on April 6, 2016, discloses a utility model entitled "A Car Counterweight Guide Rail Fixing Bracket for Elevator Guide Rails." This application discloses an elevator guide rail bracket, including a shaft wall, a support plate, a slide groove, a locking screw, a guide rail, a locking nut, a floating slide, and a counterweight. Compared with the prior art, this elevator guide rail car counterweight guide rail fixing bracket has a simple structure and powerful function. It can slide back and forth in the slide groove through the locking screw, thereby adjusting the position of the guide rail. This makes it suitable for various elevator installations and meets market demands. Furthermore, the guide rail bracket has a buffering effect during elevator operation, preventing damage to the guide rail due to vibration. However, this solution cannot compensate for guide rail deployment when there is deviation in the elevator shaft, increasing construction difficulty. Utility Model Content

[0004] This invention overcomes the problem of elevator shaft errors causing difficulties in elevator guide rail installation, and provides an elevator guide rail bracket. This solution can adjust the position of the elevator car rail and counterweight rail within a given shaft, adaptively adjust the rail installation accuracy, and ensure elevator safety.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an elevator guide rail bracket, including a bracket assembly, the bracket assembly including a mounting bracket and a connecting bracket, the mounting bracket being fixedly connected to the hoistway, and the connecting bracket being adjustablely slidably connected to the mounting bracket, a car guide rail being provided on one side of the connecting bracket, and a counterweight guide rail being provided on the other side of the connecting bracket. In this solution, the car guide rail and the counterweight guide rail are connected by the connecting bracket, and then the position of the guide rail is adjusted by the relative adjustment between the connecting bracket and the mounting bracket to meet the installation accuracy of the elevator and the guide rail, compensate for the deviation of the car guide rail and the counterweight guide rail caused by hoistway errors, and improve the stability and safety performance of the elevator.

[0006] Preferably, the mounting bracket has a fixed bracket on the side near the shaft, and the fixed bracket is fixedly connected to the shaft. Both the fixed bracket and the mounting bracket have mutually perpendicular first elongated holes. The fixed bracket provides space for the mounting bracket to be fixedly installed. The perpendicularity of the first elongated holes on the fixed bracket and the mounting bracket allows for adjustment of the relative position of the bracket assembly in the horizontal left-right direction, as well as adjustment of the length of the mounting bracket and connecting bracket in the horizontal front-back direction to compensate for errors with the shaft wall.

[0007] Preferably, a first pressure guide plate is provided on the outer side of the connecting bracket near the car guide rail, and the car guide rail is pressed onto the connecting bracket by the first pressure guide plate. The first pressure guide plate can press the car guide rail onto the connecting bracket, so that the car guide rail is more stably arranged on the connecting bracket.

[0008] Preferably, a second pressure guide plate is provided on the outer side of the connecting bracket near the counterweight guide rail, and the counterweight guide rail is pressed onto the connecting bracket by the second pressure guide plate. The second pressure guide plate can press the counterweight guide rail onto the connecting bracket, so that the counterweight guide rail is more stably arranged on the connecting bracket.

[0009] Preferably, both the connecting bracket and the mounting bracket are U-shaped angle steels, with the connecting bracket sleeved over the mounting bracket. The use of U-shaped angle steel for both the connecting bracket and the mounting bracket not only provides higher structural strength but also ensures a sliding fit between the two components, facilitating adjustment of the bracket assembly.

[0010] Preferably, the connecting bracket and the mounting bracket have a plurality of corresponding second elongated holes on at least two surfaces, and a first fastener is disposed in each of the second elongated holes. The connecting bracket and the mounting bracket can be adjusted relative to each other through the second elongated holes to compensate for the error between the connecting bracket and the shaft sidewall, and the first fastener can fix the relative position of the connecting bracket and the mounting bracket.

[0011] Preferably, the connecting bracket is an L-shaped angle steel, and the mounting bracket is a U-shaped angle steel, with a set of connecting brackets on each of the outer sides of the mounting bracket. The presence of a set of connecting brackets on each of the U-shaped sides of the mounting bracket allows for the arrangement of counterweight guide rails and car guide rails on both sides of the mounting bracket.

[0012] Preferably, the two sets of connecting brackets and mounting brackets are arranged vertically in an up-down direction. This vertical arrangement reduces the lateral installation space required for the bracket assembly, which helps to reduce construction dimensions and the difficulty of installing the guide rail.

[0013] Preferably, the connecting bracket and the mounting bracket are provided with corresponding third elongated holes, and a second fastener is disposed in the third elongated hole. The connecting bracket and the mounting bracket can be adjusted relative to each other through the third elongated holes to compensate for the error between the connecting bracket and the shaft sidewall, and the second fastener can fix the relative position of the connecting bracket and the mounting bracket.

[0014] Preferably, the support assembly consists of two sets arranged in parallel, with the car guide rails and counterweight guide rails aligned on both sets. Parallelism of the two sets of support assemblies ensures the installation accuracy of the counterweight and car guide rails, thus avoiding limitations imposed by shaft errors. Alignment of the car and counterweight guide rails on the two support assemblies results in a rational guide rail arrangement, which is beneficial for elevator assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are: (1) It can ensure the installation accuracy of the counterweight guide rail and the car guide rail, adjust the position of the elevator car rail and the counterweight rail in the predetermined shaft, and improve the safety performance of the elevator; (2) It can not only adjust the relative position of the bracket assembly in the horizontal left and right direction, but also adjust the length of the mounting bracket and the connecting bracket in the horizontal front and back direction to compensate for the error with the shaft wall; (3) The structure is reasonable, which is conducive to the installation and operation of the elevator, reduces the workload, and improves the work efficiency.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: As Figures 1 to 3 The elevator guide rail bracket shown includes a bracket assembly and a fixed bracket 6. The bracket assembly is fixed to the side wall of the shaft 3 via the fixed bracket 6. The bracket assembly includes a mounting bracket 1 and a connecting bracket 2, with the mounting bracket 1 fixedly connected to the fixed bracket 6. The mounting bracket 1 and the connecting bracket 2 can be slidably connected relative to each other, thereby adjusting the position of the connecting bracket 2 relative to the mounting bracket 1, and further adjusting the distance between the guide rail on the connecting bracket 2 and the side wall of the shaft 3 to ensure the installation requirements of the elevator car and the guide rail are met.

[0023] The fixed bracket 6 is an L-shaped connecting plate. The vertical end of the fixed bracket 6 is directly fixed to the side wall of the shaft 3, and the horizontal end of the fixed bracket 6 is directly connected to the mounting bracket 1. Specifically, the fixed bracket 6 and the side wall of the shaft 3 are connected by M10x100 expansion bolts 13. Two sets of expansion bolts 13 are provided and symmetrically arranged on the fixed bracket 6 to ensure that the fixed bracket 6 can be stably installed on the side wall of the shaft 3. In addition, a first elongated hole 7 is provided on the horizontal end of the fixed bracket 6, and a first elongated hole 7 is also provided on the mounting bracket 1. Two sets of the first elongated hole 7 are provided on both the fixed bracket 6 and the mounting bracket 1, and their positions are corresponding and perpendicular to each other. The two sets of first elongated holes 7 on the fixed bracket 6 are perpendicular to the length direction of the mounting bracket 1, and the two sets of first elongated holes 7 on the mounting bracket 1 are parallel to the length direction of the mounting bracket 1. There are two sets of bracket assemblies. By fixing the bracket 6, the distance between the two bracket assemblies can be adjusted by the two sets of first elongated holes 7. The two sets of first elongated holes 7 on the mounting bracket 1 can adjust the distance between the mounting bracket 1 and the side wall of the well 3.

[0024] The fixed bracket 6 and the mounting bracket 1 are fixedly connected by M10x50 bolts within the first elongated oval hole 7, ensuring the connection strength between them. Furthermore, the length direction of the first elongated oval hole 7 on the fixed bracket 6 is perpendicular to the length direction of the mounting bracket 1, which improves the stability of the mounting bracket 1 and ensures the bolts are centered within it. Specifically, because the first elongated oval hole 7 on the fixed bracket 6 is perpendicular to the length direction of the mounting bracket 1, the first elongated oval hole 7 on the mounting bracket 1 is positioned on its axis of symmetry. Therefore, using M10x50 bolts to fix the mounting bracket 1 ensures the bolts are centered within it, guaranteeing stability. Conversely, if the positions of the first elongated oval holes 7 on the fixed bracket 6 and the mounting bracket 1 were reversed, the bolts could not be centered within the mounting bracket 1, making it difficult to guarantee installation balance and stability.

[0025] Specifically, the connecting bracket 2 is a U-shaped angle steel structure, and the mounting bracket 1 is also a U-shaped angle steel structure. The size of the connecting bracket 2 is larger than the size of the mounting bracket 1, and the connecting bracket 2 is sleeved on the outside of the mounting bracket 1. The openings of the connecting bracket 2 and the mounting bracket 1 can face upwards or downwards without affecting the relative movement between the connecting bracket 2 and the mounting bracket 1.

[0026] In this design, the size of the connecting bracket 2 is larger than that of the mounting bracket 1, and the connecting bracket 2 is fitted over the outside of the mounting bracket 1. This minimizes the installation space of the connecting bracket 2 and the mounting bracket 1. Compared to placing the connecting bracket 2 on both sides of the mounting bracket 1, this reduces the overall lateral installation space of the mounting bracket 1 and the connecting bracket 2, ensuring sufficient space within the shaft 3.

[0027] Counterweight guide rail 5 and car guide rail 4 are respectively installed on both sides of the connecting bracket 2. The car guide rail 4 and counterweight guide rail 5 on the two bracket assemblies are aligned, which is conducive to the reasonable arrangement of the elevator car and counterweight and ensures that the elevator can operate safely and stably.

[0028] A first pressure guide plate 8 is provided on one side of the car guide rail 4. The first pressure guide plate 8 has a notch and is provided on both sides of the car guide rail 4. The bottom of the car guide rail 4 is pressed onto the connecting bracket 2 through the notches on the first pressure guide plates 8 on both sides. Then, the first pressure guide plate 8 is fixed to the connecting bracket 2 by fixing bolts. In this way, the installation of the car guide rail 4 can be realized.

[0029] A second pressure guide plate 9 is provided on one side of the counterweight guide rail 5. The second pressure guide plate 9 also has a notch. The second pressure guide plate 9 is provided on both sides of the counterweight guide rail 5. The bottom of the counterweight guide rail 5 is pressed onto the connecting bracket 2 through the notches on the second pressure guide plates 9 on both sides. Then, the second pressure guide plate 9 is fixed to the connecting bracket 2 by fixing bolts. In this way, the installation of the counterweight guide rail 5 can be realized.

[0030] Since both mounting bracket 1 and connecting bracket 2 are U-shaped, second elongated holes 10 can be provided on both sides of mounting bracket 1 and connecting bracket 2. Four sets of second elongated holes 10 are provided on each side of connecting bracket 2 and mounting bracket 1. Figure 2 and Figure 3 As shown, the multiple sets of second elongated holes 10 effectively ensure the stability of the horizontal adjustment of the connecting bracket 2 and the mounting bracket 1, and also ensure the connection strength and stability of the connecting bracket 2 and the mounting bracket 1 after installation. First fasteners 11 are arranged in the second elongated holes 10 on the mounting bracket 1 and the connecting bracket 2. Specifically, the first fasteners 11 can be M10x50 bolts.

[0031] When it is necessary to adjust the spacing between the two sets of bracket assemblies, both the fixed bracket 6 and the mounting bracket 1 need to be adjusted. Specifically, if the adjustment amount between the two sets of bracket assemblies is small, only one set of fixed bracket 6 and mounting bracket 1 needs to be adjusted. Loosen the fastening bolts and move the position of mounting bracket 1 to adjust the distance between the two sets of bracket assemblies. After the position is adjusted, re-fix mounting bracket 1.

[0032] When it is necessary to adjust the distance between the guide rail and the side wall of the shaft 3, it is preferable to adjust the relative position of the mounting bracket 1 and the connecting bracket 2. Loosen the first fastener 11, and then pull the connecting bracket 2. After the connecting bracket 2 is adjusted to the appropriate position, tighten the first fastener 11 again. If the appropriate position cannot be achieved by simply adjusting the mounting bracket 1 and the connecting bracket 2, then further adjustment can be made by adjusting the fixing bracket 6 and the first elongated hole 7 on the mounting bracket 1, in a similar manner.

[0033] It should also be noted that, since the first elongated hole 7 on the fixed bracket 6 and the mounting bracket 1 are perpendicular to each other, the mounting bracket 1 can actually produce a slight rotation effect relative to the fixed bracket 6, which can further compensate for the angle problem of the two sets of bracket components, and make the two sets of bracket components parallel, thus solving the problem of the well wall tilting caused by construction.

[0034] It should also be noted that the distance between the car guide rail 4 and the side wall of the hoistway 3 is 320mm; and since the car guide rail 4 and the counterweight guide rail 5 are basically arranged at the height of the entire hoistway 3, multiple sets of support assemblies need to be arranged in the vertical direction for the counterweight guide rail 5 and the car guide rail 4, and the distance between each set of support assemblies can be set to 1500mm.

[0035] Example 2: As Figure 4 As shown and combined as Figures 1 to 3 The elevator guide rail bracket shown includes a bracket assembly and a fixed bracket 6. The bracket assembly is fixed to the side wall of the shaft 3 via the fixed bracket 6. The bracket assembly includes a mounting bracket 1 and a connecting bracket 2, with the mounting bracket 1 fixedly connected to the fixed bracket 6. The mounting bracket 1 and the connecting bracket 2 can be slidably connected relative to each other, thereby adjusting the position of the connecting bracket 2 relative to the mounting bracket 1, and further adjusting the distance between the guide rail on the connecting bracket 2 and the side wall of the shaft 3 to ensure the installation requirements of the elevator car and the guide rail are met.

[0036] The fixed bracket 6 is an L-shaped connecting plate. The vertical end of the fixed bracket 6 is directly fixed to the side wall of the shaft 3, and the horizontal end of the fixed bracket 6 is directly connected to the mounting bracket 1. Specifically, the fixed bracket 6 and the side wall of the shaft 3 are connected by M10x100 expansion bolts 13. Two sets of expansion bolts 13 are provided and symmetrically arranged on the fixed bracket 6 to ensure that the fixed bracket 6 can be stably installed on the side wall of the shaft 3. In addition, a first elongated hole 7 is provided on the horizontal end of the fixed bracket 6, and a first elongated hole 7 is also provided on the mounting bracket 1. Two sets of the first elongated hole 7 are provided on both the fixed bracket 6 and the mounting bracket 1, and their positions are corresponding and perpendicular to each other. The two sets of first elongated holes 7 on the fixed bracket 6 are perpendicular to the length direction of the mounting bracket 1, and the two sets of first elongated holes 7 on the mounting bracket 1 are parallel to the length direction of the mounting bracket 1. There are two sets of bracket assemblies. By fixing the bracket 6, the distance between the two bracket assemblies can be adjusted by the two sets of first elongated holes 7. The two sets of first elongated holes 7 on the mounting bracket 1 can adjust the distance between the mounting bracket 1 and the side wall of the well 3.

[0037] The fixed bracket 6 and the mounting bracket 1 are fixedly connected by M10x50 bolts within the first elongated oval hole 7, ensuring the connection strength between them. Furthermore, the length direction of the first elongated oval hole 7 on the fixed bracket 6 is perpendicular to the length direction of the mounting bracket 1, which improves the stability of the mounting bracket 1 and ensures the bolts are centered within it. Specifically, because the first elongated oval hole 7 on the fixed bracket 6 is perpendicular to the length direction of the mounting bracket 1, the first elongated oval hole 7 on the mounting bracket 1 is positioned on its axis of symmetry. Therefore, using M10x50 bolts to fix the mounting bracket 1 ensures the bolts are centered within it, guaranteeing stability. Conversely, if the positions of the first elongated oval holes 7 on the fixed bracket 6 and the mounting bracket 1 were reversed, the bolts could not be centered within the mounting bracket 1, making it difficult to guarantee installation balance and stability.

[0038] Specifically, the connecting bracket 2 is an L-shaped angle steel structure, and the mounting bracket 1 is a U-shaped angle steel structure. The U-shaped opening of the mounting bracket 1 is arranged horizontally. A connecting bracket 2 is arranged on the upper and lower sides of the mounting bracket 1 respectively. When installing two sets of connecting brackets 2, one side of each set of connecting brackets 2 is connected to the upper and lower sides of the mounting bracket 1, while the other side of each set of connecting brackets 2 is located in two opposite directions of the mounting bracket 1. This allows the car guide rail 4 and the counterweight guide rail 5 to be arranged on both sides of the mounting bracket 1.

[0039] In this scheme, the connecting bracket 2 and the mounting bracket 1 are arranged vertically, which can reduce the lateral installation space of the bracket assembly, which is beneficial to reduce the construction size and the installation difficulty of the guide rail. Compared with setting the connecting bracket 2 on both sides of the mounting bracket 1, it can reduce the overall lateral installation space of the mounting bracket 1 and the connecting bracket 2, ensuring that there is sufficient space in the shaft 3.

[0040] On one side of each connecting bracket 2, there are counterweight guide rails 5 and car guide rails 4. The car guide rails 4 and counterweight guide rails 5 on the two bracket assemblies are aligned, which is conducive to the reasonable arrangement of the elevator car and counterweight and ensures that the elevator can operate safely and stably.

[0041] A first pressure guide plate 8 is provided on one side of the car guide rail 4. The first pressure guide plate 8 has a notch and is provided on both sides of the car guide rail 4. The bottom of the car guide rail 4 is pressed onto the connecting bracket 2 through the notches on the first pressure guide plates 8 on both sides. Then, the first pressure guide plate 8 is fixed to the connecting bracket 2 by fixing bolts. In this way, the installation of the car guide rail 4 can be realized.

[0042] A second pressure guide plate 9 is provided on one side of the counterweight guide rail 5. The second pressure guide plate 9 also has a notch. The second pressure guide plate 9 is provided on both sides of the counterweight guide rail 5. The bottom of the counterweight guide rail 5 is pressed onto the connecting bracket 2 through the notches on the second pressure guide plates 9 on both sides. Then, the second pressure guide plate 9 is fixed to the connecting bracket 2 by fixing bolts. In this way, the installation of the counterweight guide rail 5 can be realized.

[0043] Since mounting bracket 1 and connecting bracket 2 are aligned and fixed on one side, a third elongated hole (not shown in the figure) can be provided on the connecting side of mounting bracket 1 and connecting bracket 2. Four sets of the third elongated holes are provided on each side of connecting bracket 2 and mounting bracket 1, such as... Figure 2 and Figure 3 As shown. The multiple sets of third elongated holes effectively ensure the stability of the horizontal adjustment of the connecting bracket 2 and the mounting bracket 1, while also guaranteeing the connection strength and stability after installation. Second fasteners 12 are arranged within the third elongated holes on the mounting bracket 1 and the connecting bracket 2; specifically, the second fasteners 12 can be M10x50 bolts.

[0044] When it is necessary to adjust the spacing between the two sets of bracket assemblies, both the fixed bracket 6 and the mounting bracket 1 need to be adjusted. Specifically, if the adjustment amount between the two sets of bracket assemblies is small, only one set of fixed bracket 6 and mounting bracket 1 needs to be adjusted. Loosen the fastening bolts and move the position of mounting bracket 1 to adjust the distance between the two sets of bracket assemblies. After the position is adjusted, re-fix mounting bracket 1.

[0045] When it is necessary to adjust the distance between the guide rail and the side wall of the shaft 3, it is preferable to adjust the relative position of the mounting bracket 1 and the connecting bracket 2. Loosen the second fastener 12, and then pull the connecting bracket 2. After the connecting bracket 2 is adjusted to the appropriate position, tighten the second fastener 12 again. If the appropriate position cannot be achieved by simply adjusting the mounting bracket 1 and the connecting bracket 2, then further adjustment can be made by adjusting the fixing bracket 6 and the first elongated hole 7 on the mounting bracket 1, in a similar manner.

[0046] It should also be noted that, since the first elongated hole 7 on the fixed bracket 6 and the mounting bracket 1 are perpendicular to each other, the mounting bracket 1 can actually produce a slight rotation effect relative to the fixed bracket 6, which can further compensate for the angle problem of the two sets of bracket components, and make the two sets of bracket components parallel, thus solving the problem of the well wall tilting caused by construction.

[0047] It should also be noted that the distance between the car guide rail 4 and the side wall of the hoistway 3 is 320mm; and since the car guide rail 4 and the counterweight guide rail 5 are basically arranged at the height of the entire hoistway 3, multiple sets of support assemblies need to be arranged in the vertical direction for the counterweight guide rail 5 and the car guide rail 4, and the distance between each set of support assemblies can be set to 1500mm.
