Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail placement technology, specifically to a placement platform for elevator guide rail correction. Background Technology

[0002] Elevator guide rails are the core guiding components for elevator operation. They are typically made of high-precision cold-rolled T-shaped steel and are divided into two types: car guide rails and counterweight guide rails. They are vertically fixed to the shaft wall and connected to the elevator car / counterweight through guide shoes to ensure that the elevator runs smoothly in a straight line and prevents deviation or shaking. The guide rails must have high strength, wear resistance, and corrosion resistance to withstand the impact of frequent start-stop operations of the elevator over a long period of time. Their precision directly affects the comfort and safety of elevator operation. During installation, verticality and spacing must be strictly calibrated. In order to ensure their precision, they need to be corrected during processing and production to ensure their overall accuracy.

[0003] Currently, elevator guide rails are straightened using specialized straightening equipment, while the guide rails are manually fed via conveyor belt. However, due to the considerable length of the guide rails, straightening one rail at a time before feeding another results in a lengthy process, hindering efficient straightening. Therefore, we propose a placement platform for elevator guide rail straightening. Utility Model Content

[0004] The purpose of this utility model is to provide a placement table for elevator guide rail straightening. By setting a conveyor belt inside the support frame, the guide plates on its surface pass through the openings to the top of the support frame. The elevator guide rails are placed between the guide plates and supported on the surface of the support frame. Multiple elevator guide rails can be placed on the surface of the support frame at once before the straightening work begins. Subsequently, the guide plates are used to move the elevator guide rails one by one to the straightening work table, saving loading time and reducing the total time consumption, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a placement platform for elevator guide rail correction, comprising a support frame and rotating rollers. Rotating rollers are rotatably installed on both sides of the support frame at an upper position. The rotating rollers are connected to a stepper motor mounted on the side surface of the support frame at their ends. Circular grooves are provided around both outer rings of the rotating rollers. A conveyor belt is sleeved between the circular grooves of the two rotating rollers. A baffle plate is uniformly fixed on the surface of the conveyor belt. The baffle plate passes through a through-hole provided on the surface of the support frame to the top of the support frame.

[0006] By adopting the above technical solution, multiple elevator guide rails are placed on the support frame surface and positioned between adjacent shift plates. During subsequent material loading, the conveyor belt is driven to rotate and the shift plates are used to transfer the elevator guide rails one by one to the straightening workbench, thus achieving the purpose of adding multiple guide rails to the support frame at one time and then loading them one by one.

[0007] Optionally, the surface of the support frame is provided with raised strips, and there are three raised strips, all of which are parallel to the conveyor belt.

[0008] By adopting the above technical solution, the convex strip supports the elevator guide rail to a certain height, reduces the contact area at the bottom of the guide rail, makes it less subject to frictional resistance, and makes it easier to push.

[0009] Optionally, electric actuator feet are installed at the four bottom corners of the support frame, and there are four electric actuator feet.

[0010] By adopting the above technical solution, the height of the support frame can be changed by controlling the electric actuator feet.

[0011] Optionally, the side of the support frame is fixed with inclined guide plates, and three guide plates are provided.

[0012] By adopting the above technical solution, when the elevator guide rail is pushed down from the support frame, it can be guided by the guide plate to the surface of the straightening workbench.

[0013] Optionally, a stop bar is provided on the bottom surface of the guide plate, and a rubber sleeve is fitted around the outer ring of the stop bar.

[0014] By adopting the above technical solution, the stop bar can block and support the elevator guide rail when it slides down.

[0015] Optionally, the bottom surface of the guide plate is provided with a screw hole, and the bottom of the stop bar is installed on the bottom surface of the guide plate by screwing it into the screw hole.

[0016] By adopting the above technical solution, the stop lever can be removed and can be taken off when its blocking function is not needed.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application has a conveyor belt inside the support frame, and the dial plate on its surface passes through the through hole to the top of the support frame. The elevator guide rail is placed between the dial plate and supported on the surface of the support frame. Multiple elevator guide rails can be placed on the surface of the support frame at one time before the start of the straightening work. Subsequently, the dial plate is used to move the elevator guide rails one by one to the straightening work table, saving the material loading time and reducing the total time consumption.

[0019] 2. The technical solution of this application provides multiple parallel protrusions on the surface of the support frame, and the elevator guide rail is supported on the protrusions, which reduces the contact area and makes the sliding of the elevator guide rail smoother.

[0020] 3. The technical solution of this application provides an inclined guide plate on the side of the support frame to guide the guide rail to the straightening workbench, and a detachable stop bar can be installed as needed to prevent the elevator guide rail from sliding or to remove it.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a placement platform for elevator guide rail straightening, including a support frame 1 and a rotating roller 2. Each of the four bottom corners of the support frame 1 is equipped with an electric push rod support leg 11. There are four electric push rod support legs 11. When in use, the support frame 1 is supported by the electric push rod support legs 11 at its four bottom corners, so that it is supported on the side of the straightening workbench. The four electric push rod support legs 11 are connected to an industrial control computer and can be synchronously controlled to lift and lower, so that the height of the support frame 1 can be adjusted to adapt to straightening workbenches of different heights.

[0028] Rotary rollers 2 are rotatably installed on both sides of the upper part of the inner side of the support frame 1. The rollers 2 are connected to the stepper motors 22 installed on the side surface of the support frame 1 at their ends. Each roller 2 has an annular groove 21 around its outer side, and a conveyor belt 3 is sleeved between the annular grooves 21 of the two rollers. The surface of the conveyor belt 3 is uniformly fixed with a baffle plate 31, which passes through the through hole 12 on the surface of the support frame 1 to the top of the support frame 1.

[0029] In use, multiple elevator guide rails can be supported and placed on the upper surface of the support frame 1 at one time, and placed between different dial plates 31. When it is necessary to place the elevator guide rails on the surface of the straightening worktable, the stepper motor 22 can be controlled to drive the conveyor belt 3 to rotate, so that each dial plate 31 advances by one unit length, and all elevator guide rails are pushed to the front end, and the frontmost elevator guide rail falls onto the straightening worktable, so as to achieve the purpose of gradually adding elevator guide rails to the surface of the straightening worktable.

[0030] In addition, inclined guide plates 4 are fixed on the side of the support frame 1. There are three guide plates 4. When in use, the end of the guide plate 4 is placed above the correction workbench. After the elevator guide rail is pushed down from the support frame 1, it can slide to the surface of the support frame 1 under the guidance of the guide plate 4.

[0031] In addition, a stop bar 5 is provided on the bottom surface of the guide plate 4, and a screw hole 41 is provided on the bottom surface of the guide plate 4. The bottom of the stop bar 5 is installed on the bottom surface of the guide plate 4 by screwing it into the screw hole 41. A rubber sleeve is fitted around the outer ring of the stop bar 5. When the elevator guide rail slides down, it can be blocked by the stop bar 5 with the rubber sleeve, preventing it from sliding and hitting the straightening worktable directly. In addition, the stop bar 5 can be rotated and twisted off, and can be removed when its blocking function is not needed.

[0032] The support frame 1 is also provided with three protrusions 13, all of which are parallel to the conveyor belt 3. The elevator guide rail is supported above the support frame 1 by the protrusions 13, which reduces the contact area between the bottom of the elevator guide rail and the support frame 1, making it less subject to frictional resistance and easier to push.

[0033] In use, the support frame 1 is supported on the side of the straightening worktable by the electric push rod support leg 11. After the electric push rod support leg 11 is connected to the industrial control computer, the support frame 1 is raised and lowered by controlling the synchronous lifting of the electric push rod support leg 11, so that the bottom of the guide plate 4 is placed above the straightening worktable. The stepper motor 22 is also connected to the industrial control computer. Before the straightening work begins, the elevator guide rail to be straightened is kept perpendicular to the convex strip 13 and placed between the adjacent dial plates 31 and supported above the support frame 1 by the convex strip 13. Each time the elevator guide rail needs to be placed on the straightening worktable, the stepper motor 22 is controlled to drive the rotating roller 2 to make the conveyor belt 3 rotate. Only the frontmost elevator guide rail is pushed forward by the dial plate 31 and slid onto the straightening worktable by the guide plate 4 and blocked by the stop bar 5. Then the elevator guide rail can be placed on the straightening worktable and locked for straightening work. After all the guide rails above the support frame 1 have been conveyed to the straightening worktable, multiple more elevator guide rails can be added above the support frame 1. In addition, when feeding materials, the stop bar 5 can be rotated so that its bottom can be unscrewed from the screw hole 41 and removed, so that the front end of the guide plate 4 is unobstructed and the guide rail can slide directly onto the surface of the straightening worktable through the guide plate 4.
