Description

Technical Field

[0001] This utility model relates to a vibration detection device during elevator operation. It falls under the technical field of detection equipment. Background Technology

[0002] Currently, elevators are important transportation equipment in mining operations, and their safety is directly related to the safety and efficiency of mine production. However, existing elevator safety inspection methods mostly rely on manual inspection and regular maintenance checks. This method has problems such as long inspection cycles, low efficiency, and the test results being greatly affected by human factors.

[0003] Traditional elevator safety inspection methods typically involve professionals inspecting each component of the elevator one by one while it is stopped. However, this method is not only time-consuming and labor-intensive, but also fails to fully and accurately reflect the elevator's safety performance during actual operation. Elevators may vibrate during operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is: In order to solve the above-mentioned technical problem, this utility model provides a vibration detection device during elevator operation.

[0005] The technical solution adopted in this utility model is: a vibration detection device during elevator operation, which has the following features:

[0006] The support column can be installed inside the elevator car;

[0007] The counterweight is installed on top of the column;

[0008] The monitoring module has a monitoring plate arranged on top of the counterweight. The monitoring plate is provided with a first slide groove and a second slide groove arranged in a horizontal direction and perpendicular to each other. A first slider and a second slider that slide in cooperation with the first slide groove and the second slide groove are respectively installed in the first slide groove and the second slide groove. A pressure sensor and a warning light are provided at both ends of the first slide groove and the second slide groove. The warning light is connected to a power supply and an electromagnetic switch circuit. When the first slider and the second slider slide in the first slide groove and contact the pressure sensor, the pressure sensor can acquire a pressure signal.

[0009] The controller, pressure sensor, and electromagnetic switch are all connected to the controller. After the pressure sensor obtains the pressure signal, it sends it to the controller. The controller then controls the corresponding electromagnetic switch to close, making the circuit where the warning light is located open and illuminating the warning light.

[0010] The counterweight has a counterweight box with an opening on the front and a door that can be opened and closed. The counterweight block is arranged inside the counterweight box.

[0011] The column is equipped with a support plate at its bottom, and a base is provided below the support plate. The base has a placement groove on its top, and the support plate can be placed in the placement groove.

[0012] The base has a reel installed around the column, with a steel wire rope wound on the reel. The end of the steel wire rope is connected to a hook. Lifting lugs are installed on the side wall of the column at positions corresponding to the reel, and the hooks at the ends of the steel wire rope can be hoisted onto the lifting lugs.

[0013] The beneficial effects of this utility model are as follows: By setting a counterweight on the column and arranging a monitoring module on the counterweight, the center of gravity of the monitoring device is high under the action of the counterweight. This makes it easier for the monitoring device to tilt when the elevator vibrates during operation, facilitating the monitoring module on the counterweight to monitor the vibrations during elevator operation. Furthermore, by creating an opening in the counterweight box and installing a door panel at the opening, it is easy to place the counterweight into the box through the opening, facilitating the adjustment of the counterweight. Finally, by installing a support plate at the bottom of the column and setting a base with a placement groove below the support plate, it is convenient to... After the base is placed inside the elevator car, the support plate is placed in the placement slot of the base, which limits the horizontal movement of the detection device. Furthermore, because the base limits the movement of the bottom of the column, it facilitates the tilting of the detection device. This invention uses a reel installed on the base to wind up a steel wire rope, a hook installed at the end of the steel wire rope, and lifting lugs installed on the side wall of the column. This allows the hook to be attached to the lifting lugs after the column is placed on the base. Thus, if the detection device tilts to one side, the steel wire rope on the other side is pulled out, preventing the detection device from falling inside the elevator car under the traction of the steel wire rope.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] Example 1 is a vibration detection device during elevator operation. In this example, it has the following features:

[0021] Column 1 can be installed inside the elevator car 10;

[0022] Counterweight 2 is installed on top of column 1;

[0023] The monitoring module 3 has a monitoring plate 3-9 arranged on the top of the counterweight 2. The monitoring plate 3-9 is provided with a first slide groove 3-1 and a second slide groove 3-3 arranged in a horizontal direction. The first slide groove 3-1 and the second slide groove 3-3 are perpendicular to each other. A first slider 3-2 and a second slider 3-4 that slide in cooperation with the first slide groove 3-1 and the second slide groove 3-3 are respectively installed in the first slide groove 3-1 and the second slide groove 3-3. A pressure sensor 3-5 and a warning light 3-6 are provided at both ends of the first slide groove 3-1 and the second slide groove 3-3. The warning light 3-6 is connected to the power supply 3-8 and the electromagnetic switch 3-7. When the first slider 3-2 and the second slider 3-4 slide in the first slide groove 3-1 and the second slide groove 3-3 until they contact the pressure sensor 3-5, the pressure sensor 3-5 can obtain a pressure signal.

[0024] The controller 4, pressure sensor 3-5, and electromagnetic switch 3-7 are all communicatively connected to the controller 4. After the pressure sensor 3-5 acquires the pressure signal, it sends it to the controller 4. The controller 4 then controls the corresponding electromagnetic switch 3-7 to close, activating the circuit for the warning light 3-6 and illuminating the warning light 3-6. The counterweight 2 raises the center of gravity of the detection device. This allows the elevator to move up and down within the elevator shaft 11. After the detection device is placed inside the elevator car 10, if the elevator vibrates during operation, the detection device tilts. The first slider 3-2 and the second slider 3-4 on the monitoring module 3 slide within the first slide groove 3-1 and the second slide groove 3-3, respectively, following the tilt of the detection device. When the first slider 3-2 and the second slider 3-4 reach their ends within the first slide groove 3-1 and the second slide groove 3-3, they contact the pressure sensor 3-5 at the end. At this time, the pressure sensor 3-5 acquires the pressure signal and sends it to the controller 4. The controller 4 then controls the corresponding electromagnetic switch 3-7 to close based on the received pressure signal, activating the circuit for the warning light 3-6 and illuminating the warning light 3-6. In this way, when the elevator stops running, it is convenient for personnel to enter the elevator car 10 and check whether the warning lights 3-6 are lit to determine whether the elevator car 10 has shaken during operation.

[0025] Example 2 is a vibration detection device for elevator operation. Based on Example 1, in this example, the counterweight 2 has a counterweight box 2-1, with an opening on the front side of the counterweight box 2-1 and an openable and closable door panel 2-2 installed thereon. A counterweight block 2-3 is arranged inside the counterweight box 2-1. This allows for adjustment of the counterweight of the detection device by adjusting the counterweight block 2-3 placed inside the counterweight box 2-1.

[0026] Example 3 is a vibration detection device for elevator operation. Based on Example 1, in this example, a support plate 5 is installed at the bottom of the column 1, and a base 6 is provided below the support plate 5. A placement groove 6-1 is formed on the top of the base 6, and the support plate 5 can be placed in the placement groove 6-1. Thus, after the base 6 is placed in the elevator car 10, by placing the support plate 5 in the placement groove 6-1 of the base 6, the base 6 can effectively support the detection device in the horizontal direction. At the same time, because the bottom of the column 1 is limited, it is easier for the detection device to tilt.

[0027] In this embodiment, a reel 7 is installed on the base 6 around the column 1. A steel wire rope 8 is wound on the reel 7, and a hook is connected to the end of the steel wire rope 8. A lifting lug 9 is installed on the side wall of the column 1 at a position corresponding to the reel 7. The hook at the end of the steel wire rope 8 can be hoisted onto the lifting lug 9. This allows the column 1 to be placed on the base 6 and then hoisted onto the lifting lug 9. In this way, if the detection device tilts to one side, the steel wire rope 8 on the other side is pulled out. Under the traction of the steel wire rope 8, the detection device is prevented from falling into the elevator car 10 and colliding with the elevator car 10.

[0028] Example 4 is a vibration detection device during elevator operation. In this example, it has the following features:

[0029] Column 1 can be installed inside the elevator car 10;

[0030] Counterweight 2 is installed on top of column 1;

[0031] The monitoring module 3 has a monitoring plate 3-9 arranged on the top of the counterweight 2. The monitoring plate 3-9 is provided with a first slide groove 3-1 and a second slide groove 3-3 arranged in a horizontal direction. The first slide groove 3-1 and the second slide groove 3-3 are perpendicular to each other. A first slider 3-2 and a second slider 3-4 that slide in cooperation with the first slide groove 3-1 and the second slide groove 3-3 are respectively installed in the first slide groove 3-1 and the second slide groove 3-3. A pressure sensor 3-5 and a warning light 3-6 are provided at both ends of the first slide groove 3-1 and the second slide groove 3-3. The warning light 3-6 is connected to the power supply 3-8 and the electromagnetic switch 3-7. When the first slider 3-2 and the second slider 3-4 slide in the first slide groove 3-1 and the second slide groove 3-3 until they contact the pressure sensor 3-5, the pressure sensor 3-5 can obtain a pressure signal.

[0032] The controller 4, pressure sensor 3-5, and electromagnetic switch 3-7 are all connected to the controller 4. After the pressure sensor 3-5 obtains the pressure signal, it sends it to the controller 4. The controller 4 controls the corresponding electromagnetic switch 3-7 to close, so that the circuit of the warning light 3-6 is open and the warning light 3-6 is lit.

[0033] The counterweight 2 has a counterweight box 2-1, with an opening on the front side of the counterweight box 2-1 and an openable and closable door panel 2-2 installed therein. The counterweight block 2-3 is arranged inside the counterweight box 2-1.

[0034] The support plate 5 is installed at the bottom of the column 1, and a base 6 is provided below the support plate 5. The top of the base 6 is provided with a placement groove 6-1, and the support plate 5 can be placed in the placement groove 6-1.

[0035] A reel 7 is installed on the base 6 around the column 1. A steel wire rope 8 is wound on the reel 7. A hook is connected to the end of the steel wire rope 8. A lifting lug 9 is installed on the side wall of the column 1 at the position corresponding to the reel 7. The hook at the end of the steel wire rope 8 can be hoisted onto the lifting lug 9.

[0036] 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.
