Description

Technical Field

[0001] This utility model belongs to the technical field of elevator guide rail installation, and more specifically, it relates to a quick installation and fixing device for elevator guide rails. Background Technology

[0002] Elevator guide rails are the guiding components for the vertical movement of the elevator car and counterweight. Like train tracks, they provide precise guidance for the elevator's vertical movement. The elevator car and counterweight move up and down along the car guide rails and counterweight guide rails respectively, ensuring that the elevator does not sway or deviate during operation, thus guaranteeing the smoothness and safety of elevator operation. The most common type of elevator guide rail is T-shaped.

[0003] The existing elevator guide rail installation process typically involves driving expansion bolts into the elevator shaft, securing the guide rail bracket with expansion bolts, and then hoisting the guide rail into the elevator shaft using other devices. The guide rail is then fixed to the guide rail bracket using bolts and other devices. However, because the guide rail is hoisted into the elevator shaft without a fixing device, it may sway during installation. If workers manually hold the guide rail, various factors may cause it to lose its level, leading to the need for disassembly and reinstallation after installation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick installation and fixing device for elevator guide rails. This solves the technical problem that in existing technologies, guide rails are hoisted into the elevator shaft by other devices without a fixing device, which may cause them to sway during installation. If workers hold the guide rails by hand, various factors may cause the guide rails to lose their horizontal position, resulting in the need for disassembly and reinstallation after installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick installation and fixing device for elevator guide rails, comprising a guide rail bracket one, a guide rail bracket two on the guide rail bracket one, two sets of bolts threadedly connected to the guide rail bracket two, both sets of bolts being threadedly connected to the guide rail bracket one, both the guide rail bracket one and the guide rail bracket two having two sets of holes three, both sets of holes three having a frame body movably passing through them, both sets of frame bodies being rotatably connected to a double-ended threaded rod, the double-ended threaded rod being threadedly connected to two sets of clamps, one end of the guide rail bracket one having a hole one, and one end of the guide rail bracket two having a hole two.

[0006] As a preferred technical solution of this utility model, one end of the clamp is connected to a block, the block is movably penetrated by a column, one end of the column is connected to a plumb line, and one end of the block is provided with a groove.

[0007] As a preferred embodiment of this utility model, the guide rail bracket has a reinforcing rib connected to one end.

[0008] As a preferred embodiment of this utility model, a handwheel is connected to one end of the double-threaded rod.

[0009] As a preferred embodiment of this utility model, the two sets of frame bodies are connected by rods, and the rods are slidably connected to the two sets of clamps.

[0010] As a preferred embodiment of this utility model, one end of each of the two sets of clamps is connected to a rubber pad.

[0011] As a preferred embodiment of this utility model, a washer is connected to one end of each of the two sets of bolts.

[0012] This utility model provides a quick installation and fixing device for elevator guide rails, which has the following advantages:

[0013] 1. By cooperating with the double-ended threaded rod, clamp, and frame, and by engaging the expansion bolts pre-drilled into the elevator shaft wall through the hole one, guide rail bracket one is fixed to the inner wall of the elevator shaft. Guide rail bracket two is placed close to guide rail bracket one, and bolts are screwed into guide rail bracket one to fix guide rail bracket one and guide rail bracket two together. The frame is then inserted into guide rail bracket one and guide rail bracket two. Rotating the double-ended threaded rod moves the clamp to hold the hoisted elevator guide rail. This method, to a certain extent, prevents the elevator guide rail from shaking during installation, which could lead to a failure to maintain a horizontal position and thus require disassembly and reinstallation of the elevator guide rail.

[0014] 2. By coordinating the blocks, columns, and plumb line, the column is inserted into the block. The plumb line is used to test the perpendicularity of guide rail bracket one and guide rail bracket two. This avoids, to some extent, the guide rail inheriting the deviation of the bracket after it is installed on the guide rail due to the excessive perpendicularity deviation between guide rail bracket one and guide rail bracket two, making it difficult to adjust the perpendicularity of the guide rail to the standard range.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: a quick installation and fixing device for elevator guide rails, including a guide rail bracket 1, a guide rail bracket 2 on the guide rail bracket 1, and two sets of bolts 3 threadedly connected to the guide rail bracket 2. Tightening the bolts 3 fixes the guide rail bracket 1 and the guide rail bracket 2 together. Both sets of bolts 3 are threadedly connected to the guide rail bracket 1. Both the guide rail bracket 1 and the guide rail bracket 2 have two sets of holes 18, and a frame 4 is movably inserted through each of the two sets of holes 18. The frame 4 is inserted into the holes 18. A double-ended threaded rod 5 is rotatably connected to the two sets of frame 4. Rotating the double-ended threaded rod 5 moves the clamp 6, clamping the hoisted guide rail. After installation, the frame 4 can be removed and placed on other guide rail brackets. The double-threaded rod 5 is threaded with two sets of clamps 6. The shape of the clamps 6 matches the T-shaped guide rail. One end of the guide rail bracket 1 has a hole 10 at the other end. The guide rail bracket 1 is fixed to the inner wall of the elevator shaft by cooperating with the expansion bolt through the hole 10. One end of the guide rail bracket 2 has a hole 24 at the other end. The guide rail can be fixed on the guide rail bracket 2 through the hole 24. The guide rail is clamped by the clamps 6, which to a certain extent avoids the problem of the hoisted guide rail shaking due to other factors, resulting in deviation in levelness, and requiring disassembly and reinstallation.

[0025] One end of a set of clamps 6 is connected to a block 16, through which a column 7 is movably inserted. One end of the column 7 is connected to a plumb bob 8, which is a tool for testing verticality. This is existing technology and will not be described in detail here. One end of the block 16 has a groove 17. The plumb bob 8 is moved a certain distance along the groove 17, and the column 7 is inserted into the hole in the block 16. The verticality of the guide rail bracket 1 and the guide rail bracket 2 is tested by the plumb bob 8. This avoids excessive verticality deviation, which would cause the guide rail to inherit the deviation of the bracket after it is installed, making it difficult to adjust the verticality of the guide rail to the standard range.

[0026] Among them, one end of the guide rail bracket 1 is connected to a reinforcing rib 9, which strengthens the structural strength of the guide rail bracket 1 to a certain extent, thereby enhancing the load-bearing capacity of the guide rail bracket 1.

[0027] The double-threaded rod 5 is connected to a handwheel 11 at one end, which makes it easier to rotate the double-threaded rod 5.

[0028] Among them, two sets of frame bodies 4 are connected to rod bodies 12, and the rod bodies 12 are slidably connected to two sets of clamps 6, and the rod bodies 12 guide the clamps 6.

[0029] Both sets of clamps 6 have a rubber pad 13 connected to one end, which can improve the clamping stability to a certain extent.

[0030] Both sets of bolts 3 have washers 15 connected to one end, which to a certain extent prevents the bolts 3 from loosening due to vibrations caused by elevator operation.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In use, expansion bolts are driven into the corresponding positions on the inner wall of the elevator shaft. The guide rail bracket 1 is fixed to the inner wall of the elevator shaft by engaging the expansion bolts with the hole 10. The guide rail bracket 2 is then placed flush against the guide rail bracket 1, and bolts 3 are screwed in to secure them together. A plumb line 8 is moved along the groove 17, and after a certain distance, the column 7 is placed into the block 16. The plumb line 8 is used to test the perpendicularity of the guide rail bracket 2 and the guide rail bracket 1, thus preventing excessive perpendicularity deviation that could cause the guide rail to malfunction after installation. The deviation makes it difficult to adjust the verticality of the guide rail to the standard range. Move the frame 4 along the hole 18, rotate the double-headed threaded rod 5 to drive the two sets of clamps 6 to move. The clamps 6 clamp the hoisted elevator guide rail and fix the elevator guide rail to the guide rail bracket 2 through the hole 14. The clamps 6 clamp the elevator guide rail to a certain extent to avoid the elevator guide rail shaking during installation, which would cause errors in the horizontality of the elevator guide rail after installation and require disassembly and reinstallation. After the installation is completed, the frame 4 can be removed and placed on other guide rail brackets for use, which has a wide range of applications.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
