Technical Field

[0001] The present application relates to the technical field of testing equipment, and in particular to a sliding guide shoe lining wear testing device. Background Art

[0002] In modern elevator technology, guide shoes are key components of elevator cars and counterweights. Their performance directly impacts the smoothness, safety, and reliability of elevator operation. Guide shoes contact the guide rails via rollers, guiding the car or counterweight.

[0003] However, existing sliding guide shoe lining wear test devices usually use pressure to make the shoe lining fit with the friction plate when simulating the movement between the guide shoe and the guide rail. When the shoe lining is worn to a certain extent, the shoe lining and the friction plate cannot be separated without human intervention, resulting in almost complete wear of the shoe lining and inability to provide effective side data of the shoe lining. Summary of the Invention

[0004] In order to improve the problem that the existing sliding guide shoe lining wear test device cannot separate the shoe lining and the friction plate without manual intervention, the present application provides a sliding guide shoe lining wear test device.

[0005] The present application provides a sliding guide shoe lining wear test device that adopts the following technical solution: A sliding guide shoe lining wear test device, comprising: The friction plate is rotatable and is used to simulate the guide rails of an elevator. A limiting assembly is used to limit the position of the shoe lining so that the shoe lining abuts against or separates from the friction plate; The pressure component abuts against the limit component and is used to connect with a heavy object to change the pressure between the shoe lining and the friction plate.

[0006] By adopting the above technical solution, the friction plate can simulate the relative movement between the guide rail and the shoe lining during elevator operation, thereby realistically reproducing the wear conditions of the shoe lining in actual use, providing a reliable motion basis for the test. The limit assembly can achieve contact or separation with the friction plate according to the test requirements, avoiding the tedious process of manual operation to separate the shoe lining and the friction plate, reducing the interference of human factors on the test results, and improving the problem that the existing sliding guide shoe lining wear test device cannot separate the shoe lining and the friction plate without human intervention. The pressure assembly adjusts the pressure between the shoe lining and the friction plate by connecting a heavy object.

[0007] Preferably, it further comprises a rotating table, wherein the fixed end of the rotating table is fixedly connected to any horizontal plane, the movable end of the rotating table is detachably connected to the friction plate, and the rotating table is used to drive the friction plate to rotate.

[0008] By adopting the above technical solution, the rotating table can realize the continuous rotation of the friction plate, thereby driving the friction plate to simulate the relative motion state of the elevator guide rail in actual operation.

[0009] Preferably, the limiting assembly includes a clamp and a limiting block. The clamp is arranged relative to the friction plate. The clamp is used to limit the position of the boot lining so that the boot lining abuts or separates from the friction plate. The limiting block is arranged relative to the friction plate. The limiting block abuts against the clamp. The limiting block is used to limit the position of the clamp to ensure the stability of the position of the boot lining.

[0010] By adopting the above technical solution, the clamp can limit the position of the boot lining, ensuring that the boot lining always remains on the predetermined motion trajectory during the test. The limit block can limit the position of the clamp, thereby further limiting the position of the boot lining, thereby avoiding affecting the contact state between the boot lining and the friction plate.

[0011] Preferably, the clamp includes an abutment block, a first connecting block and a second connecting block, the abutment block is slidably connected to the first connecting block, the abutment block is used to provide a buffer for the first connecting block, the second connecting block is detachably connected to the first connecting block, and the second connecting block is used to abut against the boot lining to connect the first connecting block and the boot lining.

[0012] By adopting the above technical solution, the abutment block is slidably connected to the first connecting block, which can provide a buffer for the first connecting block when the rotation speed of the friction plate changes, simulating the real elevator movement and ensuring the validity of the side data of the shoe lining.

[0013] Preferably, protrusions are provided on both sides of the first connecting block, and the protrusions are used to abut against the limiting blocks to limit the position of the shoe lining.

[0014] By adopting the above technical solution, the abutment between the protrusion and the limit block can ensure that the wear degree of each shoe lining is the same during the test, thereby eliminating the situation of excessive wear or insufficient wear and improving the accuracy of the test results.

[0015] Preferably, a notch portion for accommodating the clamp is provided on one side of the limiting block, the length of the notch portion is greater than the length of the first connecting block, and the height of the notch portion is greater than the height of the first connecting block.

[0016] By adopting the above technical solution, the notch ensures that the first connecting block can be completely embedded in the notch, while providing sufficient space for the movement of the clamp, avoiding the jamming phenomenon caused by size limitations, thereby simulating the actual operating state of the elevator.

[0017] Preferably, the pressure assembly includes a bracket, a rotating rod, an abutment rod and a connecting rod. The bracket is vertically arranged, the rotating rod is rotatably connected to the bracket, the abutment rod is fixedly arranged at one end of the rotating rod, the abutment rod is used to abut against the abutment block to limit the position of the abutment block, and the connecting rod is fixedly arranged at one end of the rotating rod away from the abutment rod, and the connecting rod is used to connect with a heavy object to change the pressure between the abutment rod and the abutment block.

[0018] By adopting the above technical solution, the pressure component can transmit external force to the clamp, and then act on the shoe lining, simulating the pressure between the shoe lining and the guide rail when the elevator is running.

[0019] Preferably, it also includes a storage rack, which is detachably provided with a first container, which is arranged opposite to the friction plate, and contains fluid. The first container is provided with a through hole for the fluid to flow out, and the first container is used to flow the fluid toward the friction plate so that the surface of the friction plate is covered with the fluid.

[0020] By adopting the above technical solution, fluid flows to the surface of the friction plate, so that the test device can more realistically simulate the wear conditions of the boot lining in actual use, providing a reliable test means for studying the wear characteristics of the boot lining under different lubrication or cooling conditions, and improving the credibility of the side data provided by the boot lining.

[0021] Preferably, the storage rack can also be rotatably provided with a second container, in which particulate matter is provided. The second container has holes for discharging the particulate matter, and the first container is used to discharge the particulate matter toward the friction plate so that the surface of the friction plate is covered with the particulate matter.

[0022] By employing this technical solution to discharge particulate matter onto the friction plate surface, the second container can simulate the abrasive wear environment found in actual operating conditions. Abrasive wear is a significant form of wear that shoe linings may encounter in actual use. This approach allows for a more comprehensive study of the wear resistance of shoe linings and enhances the credibility of the indirect data provided by the linings.

[0023] Preferably, the storage rack is further fixedly provided with a driving member, and the movable end of the driving member is used to contact the second container when swinging, so as to drive the second container to swing.

[0024] By adopting the above technical solution, the movable end of the driving member contacts the second container during the swinging process, and this contact applies an external force, causing the second container to swing. This swinging can disturb the particles in the container, preventing the particles from accumulating or clogging the discharge hole due to static state.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1.

The limit assembly can abut or separate from the friction plate according to test requirements, avoiding the tedious process of manually separating the shoe lining and friction plate, reducing human interference with test results, and improving the existing sliding guide shoe lining wear test device. The problem of being unable to separate the shoe lining and friction plate without manual intervention is solved. The pressure assembly adjusts the pressure between the shoe lining and friction plate by connecting a weight. 2. The rotating table can realize the continuous rotation of the friction plate, thereby driving the friction plate to simulate the relative motion state of the elevator guide rail in actual operation; 3. The fixture can limit the position of the boot lining to ensure that the boot lining always remains on the predetermined motion trajectory during the test. The limit block can limit the position of the fixture, thereby further limiting the position of the boot lining, thereby avoiding affecting the contact state between the boot lining and the friction plate.

[0028] The following is combined with Figure 1-6 This application is described in further detail.

[0029] The present application discloses a sliding guide shoe lining wear test device. Figure 1 and Figure 2 The sliding guide shoe lining wear test device includes a rotating table 1, a limiting component 2, a pressure component 3 and a storage rack 4.

[0030] like Figure 1 and Figure 2 As shown, the fixed end of the turntable 1 is fixedly connected to any horizontal plane, and the movable end of the turntable 1 is detachably provided with a friction plate 5, which is used to simulate the guide rail during elevator operation. The turntable 1 is used to drive the friction plate 5 to rotate, thereby realizing continuous rotation of the friction plate 5, so that the friction plate 5 simulates the relative motion state of the elevator guide rail during actual operation.

[0031] For example, the friction plate 5 is a ring-shaped metal plate, the turntable 1 is an electric turntable, the surface of the friction plate 5 is smooth, and the turntable 1 is horizontally arranged. When the movable end of the turntable 1 rotates, the friction plate 5 can be driven to rotate around the axis in the horizontal direction, simulating the relative movement between the guide rail and the shoe lining 6 when the elevator is running, thereby reproducing the wear condition of the shoe lining 6 in actual use, providing a reliable motion basis for the test.

[0032] like Figure 2 and Figure 3 As shown, the limiting assembly 2 includes a clamp 21 and a limiting block 22. The clamp 21 is arranged opposite to the friction plate 5. The clamp 21 is used to limit the position of the boot lining 6 so that the boot lining 6 is in contact with or separated from the friction plate 5. The limiting block 22 is arranged opposite to the friction plate 5. The limiting block 22 is in contact with the clamp 21. The limiting block 22 is used to limit the position of the clamp 21 to ensure the stability of the position of the boot lining 6. The clamp 21 can limit the position of the boot lining 6 to ensure that the boot lining 6 always remains on the predetermined motion trajectory during the test. The limiting block 22 can limit the position of the clamp 21, thereby further limiting the position of the boot lining 6, thereby avoiding affecting the contact state between the boot lining 6 and the friction plate 5.

[0033] In an embodiment of the present application, the clamp 21 includes an abutment block 211, a first connecting block 212 and a second connecting block 213. The abutment block 211 is slidably connected to the first connecting block 212. The abutment block 211 is used to provide a buffer for the first connecting block 212. The second connecting block 213 is detachably connected to the first connecting block 212. The second connecting block 213 is used to abut against the boot lining 6 to connect the first connecting block 212 and the boot lining 6. The abutment block 211 is slidably connected to the first connecting block 212, and can provide a buffer for the first connecting block 212 when the rotation speed of the friction plate 5 changes, simulating the actual elevator movement situation and ensuring that the side data of the boot lining 6 is valid.

[0034] For example, please refer to Figure 3 and Figure 4The first and second connecting blocks 213 are all metal blocks, and one end of the abutment block 211 is provided with an arc groove for abutting with any columnar object, and the end of the abutment block 211 away from the arc groove is provided with a dovetail groove, and the side wall of the first connecting block 212 is provided with a dovetail tenon, and the abutment block 211 is slidably connected through the dovetail groove and the dovetail tenon, and the side wall of the first connecting block 212 is also provided with a plurality of holes for screws to pass through, and the side wall of the second connecting block 213 is provided with holes of the same specification as the holes of the first connecting block 212. The first connecting block 212 and the second connecting block 213 are detachably connected by screws passing through the corresponding holes of the two. The position of the second connecting block 213 relative to the first connecting block 212 can be changed by changing the hole of the second connecting block 213 corresponding to the hole of the first connecting block 212; there are two second connecting blocks 213, and the two second connecting blocks 213 respectively abut against the side walls corresponding to the shoe lining 6 through the side walls, thereby limiting the position of the shoe lining 6.

[0035] Optionally, in order to further ensure that the position of the shoe lining 6 is stable during testing, the side of the shoe lining 6 away from the friction plate 5 is detachably connected to the first connecting block 212 through materials or structures such as adhesives.

[0036] like Figure 2 and Figure 3 As shown, a notch 23 for accommodating the clamp 21 is provided on one side of the limit block 22. The length of the notch 23 is greater than the length of the first connecting block 212, and the height of the notch 23 is greater than the height of the first connecting block 212. Optionally, a rotating wheel is rotatably provided on the side wall of the notch 23. The rotating wheel is used to abut against the clamp 21 to prevent direct friction between the clamp 21 and the limit block 22. The notch 23 ensures that the first connecting block 212 can be fully embedded in the notch 23, while providing sufficient space for the movement of the clamp 21, avoiding jamming due to size limitations, thereby simulating the actual operating state of the elevator.

[0037] It should be noted that in the embodiment of the present application, protrusions 214 are provided on both sides of the first connecting block 212. The protrusions 214 are used to abut against the limit block 22 to limit the position of the boot lining 6. The abutment between the protrusions 214 and the limit block 22 can ensure that the degree of wear of each boot lining 6 is the same during the test, thereby eliminating excessive wear or insufficient wear and improving the accuracy of the test results.

[0038] Specifically, the first connecting block 212 can be mounted on the limit block 22 through the protrusion 214, and the first connecting block 212 is located in the notch 23; the boot lining 6 is detachably arranged at the bottom of the first connecting block 212. Since the boot lining 6 has a certain thickness, the boot lining 6 lifts the first connecting block 212 at the beginning of the test, and the protrusion 214 of the first connecting block 212 is separated from the limit block 22; during the test, the boot lining 6 wears and becomes thinner after friction with the friction plate 5. At this time, the protrusion 214 abuts against the limit block 22, limiting the position of the boot lining 6 in the vertical direction, so that the boot lining 6 no longer contacts the friction plate 5; the limit assembly 2 can abut or separate from the friction plate 5 according to the test requirements, avoiding the tedious process of manual operation to separate the boot lining 6 from the friction plate 5, reducing the interference of human factors on the test results, and improving the problem that the existing sliding guide shoe boot lining wear test device cannot separate the boot lining 6 and the friction plate 5 without manual intervention.

[0039] like Figure 2 As shown, the pressure assembly 3 includes a bracket 31, a rotating rod 32, an abutting rod 33 and a connecting rod 34. The bracket 31 is vertically arranged, the rotating rod 32 is rotatably connected to the bracket 31, the abutting rod 33 is fixedly arranged at one end of the rotating rod 32, the abutting rod 33 is used to abut against the abutting block 211 to limit the position of the abutting block 211, and the connecting rod 34 is fixedly arranged at the end of the rotating rod 32 away from the abutting rod 33. The connecting rod 34 is used to connect with a weight to change the pressure between the abutting rod 33 and the abutting block 211; the pressure assembly 3 can transmit external force to the clamp 21, and then act on the boot lining 6 to simulate the pressure between the boot lining 6 and the guide rail when the elevator is running; the pressure assembly 3 adjusts the pressure between the boot lining 6 and the friction plate 5 by connecting a weight; exemplarily, the bracket 31 is vertically arranged on any horizontal plane such as the ground or the fixed end of the rotating table 1.

[0040] like Figure 5 As shown, the storage rack 4 is detachably provided with a first container 41, which is arranged opposite to the friction plate 5. Fluid is provided in the first container 41, and the first container 41 is provided with a through hole for the fluid to flow out. The first container 41 is used to flow the fluid toward the friction plate 5 so that the surface of the friction plate 5 is covered with the fluid; the flow of fluid toward the surface of the friction plate 5 enables the test device to more realistically simulate the wear conditions of the boot lining 6 in actual use, provides a reliable test means for studying the wear characteristics of the boot lining 6 under different lubrication or cooling conditions, and improves the credibility of the side data provided by the boot lining 6.

[0041] Exemplarily, the first container 41 is a plastic bottle, and the first container 41 is set on one side of the shelf 4 through a metal sheet that is detachably connected to the shelf 4. The first container 41 is set vertically, and the first container 41 has an air hole, so that the first container 41 can automatically drip fluid through air pressure balance; the fluid is lubricating oil.

[0042] like Figure 5 and Figure 6 As shown, the rack 4 is also rotatably provided with a second container 42. This second container 42 contains particulate matter and has holes for the discharge of the particulate matter. The first container 41 is used to discharge the particulate matter onto the friction plate 5, thereby covering the surface of the friction plate 5 with the particulate matter. By discharging particulate matter onto the surface of the friction plate 5, the second container 42 can simulate the abrasive wear environment encountered in actual operating conditions. Abrasive wear is a significant form of wear that the shoe lining 6 may encounter in actual use. This method allows for a more comprehensive study of the wear resistance of the shoe lining 6, improving the credibility of the indirect data provided by the shoe lining 6.

[0043] In the embodiment of the present application, the storage rack 4 is also fixedly provided with a driving member 43. The movable end of the driving member 43 is used to contact the second container 42 when swinging to drive the second container 42 to swing. The movable end of the driving member 43 contacts the second container 42 during the swinging process. Through this contact, an external force is applied to cause the second container 42 to swing, thereby disturbing the particulate matter in the container and preventing the particulate matter from accumulating or clogging the discharge hole due to standing still.

[0044] Exemplarily, the second container 42 is a plastic bottle, and the second container 42 is arranged on the other side of the rack 4 through a metal sheet hinged to the rack 4. A protrusion is provided on the top of the second container 42, and the driving member 43 is specifically a metronome. The movable end of the driving member 43 is used to contact or separate from the protrusion on the top of the second container 42 during the swinging process to drive the second container 42 to swing.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
