Description

Technical Field

[0001] The utility model belongs to the technical field of rotary kiln leakage detection, and in particular relates to a rotary kiln motor leakage detection system. Background Art

[0002] Rotary kiln motors are heavy equipment used in industrial production, mainly used in processes such as heat treatment, drying and chemical reactions of materials. This type of motor is usually large in size and high in power, and is commonly found in mines, chemical plants, cement plants and other places. Detecting the leakage of the rotary kiln motor casing is a key safety operation to ensure that the electrical insulation performance of the equipment is good when it is running.

[0003] At present, the main equipment used for rotary kiln motor housing leakage detection includes multimeter and megohmmeter. Multimeter is used to measure the resistance value, detect the resistance between the motor housing and the ground or power line, to determine whether there is leakage. Megohmmeter measures the insulation resistance between the motor housing and the ground by applying a certain test voltage, so as to determine whether the rotary kiln motor housing is leaking.

[0004] The above leakage detection equipment still has safety hazards. Specifically, the rotary kiln motor usually works under high voltage and high power. If the operator does not wear insulating gloves, insulating clothing and other protective gear during the maintenance process, electric shock accidents are likely to occur. In addition, due to the large size of the rotary kiln motor, and the motor is usually installed on the bracket of the rotary kiln power unit, the entire rotary kiln together with the bracket is set on the maintenance platform. Maintenance often requires working at high altitudes, which increases the probability of accidents. It can be seen that in the field of rotary kiln detection, it is urgent to design a leakage detection system for rotary kiln motors to fully protect the lives of maintenance personnel. Utility Model Content

[0005] The purpose of the utility model is to provide a leakage detection system for a rotary kiln motor in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A leakage detection system for a rotary kiln motor includes a leakage detection device and a storage mechanism with a built-in protective gear room and an equipment room, and the equipment room is used to store the leakage detection device. The storage mechanism has a first opening corresponding to the protective gear room and a second opening corresponding to the equipment room, the first opening is arranged outside the storage mechanism, and the second opening is arranged inside the storage mechanism. When the first opening is in a closed state, the second opening and the equipment room are isolated from the external space of the storage mechanism. Before the maintenance personnel use the leakage detection device, they first open the first opening, wear insulating protective gear, and then take the leakage detection device out of the equipment room. In the specific taking-out process, the leakage detection device first passes through the second opening, enters the protective gear room from the equipment room, and then passes through the first opening to move to the outside of the storage mechanism.

[0008] As a further optimization solution of the present utility model, the storage mechanism further includes a cabinet and a box body arranged on the cabinet, the first opening is arranged on the cabinet, and the second opening is arranged on the box body.

[0009] As a further optimization solution of the present invention, a sealing component is provided inside the second opening.

[0010] As a further optimization solution of the utility model, the sealing component is a carrier frame slidably arranged on the inner side of the second opening, the carrier frame is used to place the leakage detection equipment, and a linear drive component for moving the carrier frame is provided on the inner side of the box body.

[0011] As a further optimization solution of the present invention, the sealing component is a plate body slidably arranged inside the second opening.

[0012] As a further optimization solution of the utility model, a lifting mechanism for carrying people is provided on one side of the storage mechanism.

[0013] As a further optimization solution of the utility model, the lifting mechanism includes a folding lifting platform, and a workbench is slidably provided on the top of the folding lifting platform.

[0014] As a further optimization solution of the utility model, the workbench is slidably connected to the folding lifting platform through a slide rail, and positioning members and ladders are provided on both sides of the folding lifting platform, and the positioning members are used to fix the workbench.

[0015] The beneficial effects of the utility model are:

[0016] 1) When the first opening of the utility model is in a closed state, the second opening and the equipment room are isolated from the external space of the storage mechanism. The maintenance personnel need to open the first opening before taking the leakage detection device, put on the protective gear, take the leakage detection device from the equipment room to the protective gear room, and then take the leakage detection device out of the storage mechanism. The storage mechanism restricts the order in which the maintenance personnel take the protective gear and the detection device, so as to avoid the maintenance personnel using the leakage detection device to perform leakage detection on the motor housing when they are not wearing insulating protective gear due to negligence, thereby improving the safety performance of the detection system;

[0017] 2) The utility model integrates the leakage detection device, the storage mechanism of the detection device and the protective gear, and the manned lifting mechanism, which improves the convenience of the maintenance workers in detecting the leakage of the motor, so that the leakage detection system can be applied to the high-power motor for the rotary kiln;

[0018] 3) The utility model sets a workbench on the lifting mechanism for placing leakage detection equipment. Before maintenance, the position of the workbench can be adjusted according to the specific position of the part to be detected of the rotary kiln motor. Positioning parts and ladders are set on both sides of the folding lifting platform. Maintenance personnel can use the positioning parts to lock the workbench according to the position of the workbench, and reach the top of the lifting platform through the ladder away from the workbench, so as to further improve the convenience of maintenance work.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

Specifically, the first opening 23 is provided on the front side wall of the cabinet 25, and the second opening 24 is provided at the bottom of the box 26 and is connected to the protective gear room 21 and the equipment room 22 respectively. When the cabinet door 29 is closed, the first opening 23 is closed, and the second opening 24 and the equipment chamber 22 are isolated from the external space of the storage mechanism 2 .

[0028] Before the maintenance personnel use the megohmmeter, they first open the cabinet door 29, so that the first opening 23 and the protective gear room 21 are opened, and the insulating protective gear in the protective gear room 21 is put on, and then the megohmmeter is taken out from the equipment room 22. In the specific taking-out process, the megohmmeter first passes through the second opening 24, enters the protective gear room 21 from the equipment room 22, and then passes through the first opening 23 to move to the outside of the storage mechanism 2. The storage mechanism 2 can limit the order in which the maintenance personnel use the insulating protective gear and the megohmmeter, so as to avoid the maintenance personnel from using the leakage detection equipment to perform leakage detection on the motor housing due to negligence without wearing the insulating protective gear. When testing whether the rotary kiln motor is leaking, the two test wires of the megohmmeter are firmly connected to the housing and power cord of the rotary kiln motor respectively. After starting the megohmmeter, the leakage condition of the housing of the rotary kiln motor is judged according to the reading of the megohmmeter. In addition, in some other embodiments, the megohmmeter can also be replaced by a multimeter or other leakage detection instruments.

[0029] Furthermore, if Figure 3As shown, a sealing member 27 is provided inside the second opening 24. The sealing member 27 in this embodiment is a carrier frame slidably arranged inside the second opening 24, the carrier frame is used to place the megohmmeter, at least one opening is provided on the side wall of the carrier frame for taking and placing the megohmmeter, and a linear drive member 28 for moving the carrier frame is provided inside the box 26. The linear drive member 28 is preferably a drive motor fixedly arranged below the top wall of the box 26 and a screw rod fixedly arranged at the output end of the drive motor, a nut pair corresponding to the screw rod is fixedly arranged on the top of the rear side of the carrier frame, and the drive motor drives the carrier frame to move up and down through the screw rod and the nut pair. A button corresponding to the drive motor is provided on the inner wall of the cabinet 25. In addition, in some other embodiments, the box 26 can also be arranged on the side wall of the cabinet 25, or the box 26 can be arranged inside the cabinet 25.

[0030] Preferably, if Figure 1 , 2 As shown in Figures 4 and 5, a lifting mechanism 3 for manning is provided on one side of the storage mechanism 2. The lifting mechanism 3 includes a folding lifting platform 31, and a workbench 32 is slidably provided on the top of the folding lifting platform 31. The workbench 32 is slidably connected to the folding lifting platform 31 through a slide rail 33. The number of the slide rails 33 is preferably two. The lower part of the workbench 32 has two groups of legs, and the two groups of legs are slidably connected to the slide rail 33. Positioning members 34 and ladders 35 are provided on both sides of the folding lifting platform 31. The ladder 35 is fixed at the bottom of the folding lifting platform 31. The positioning member 34 is preferably a magnet for fixing the workbench 32. The legs of the workbench 32 are made of ferromagnetic metal so that the positioning member 34 can fix the workbench 32 by magnetic attraction. The maintenance personnel can fix the workbench 32 by magnets, and climb to the top of the folding lifting platform 31 by ladder 35, and the maintenance personnel are transported to the height of the leakage detection working surface by the folding lifting platform 31. In addition, in some other embodiments, the lifting mechanism 3 may not be provided, and the maintenance personnel may use a stepladder or other carrier to reach the height of the working surface to perform leakage detection on the motor housing of the rotary kiln.

[0031] Second embodiment
