Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mining electrical appliances, in particular to an interlocking mechanism of a mining explosion-proof vacuum electromagnetic starter. Background Art
[0002] The explosion-proof vacuum electromagnetic starter for mining is mainly used to control the direct start, stop and forward and reverse operation of mining motors, and can protect mining motors from overload and phase failure. With the widespread application of remote control technology, more and more switches are being debugged and tested. In order to ensure safety, the door of the explosion-proof vacuum electromagnetic starter for mining is first translated and then rotated to open, and the reversing knob switch, test button and door have the following interlocking relationship:
[0003] 1. When opening the box door, the reversing knob switch must be in the off position and the test button must not be pressed;
[0004] 2. When the reversing knob switch is in the forward or reverse position, the box door must be closed and the test button must not be pressed;
[0005] 3. When the test button is pressed, the box door must be closed and the reversing knob switch must be in the off position.
[0006] The existing mine flameproof vacuum electromagnetic starter relies on a complex mechanism to realize the interlocking between the reversing knob switch, the test button and the box door, which is prone to mechanical failure, and maintenance and repair are also very troublesome, delaying production. Therefore, it is necessary to design a simple and reliable interlocking mechanism. Utility Model Content
[0007] In order to overcome the shortcomings of the background technology, the utility model discloses an interlocking mechanism of a mine flameproof vacuum electromagnetic starter, and the interlocking mechanism of the mine flameproof vacuum electromagnetic starter adopts the following technical solutions:
[0008] An interlocking mechanism of a mine explosion-proof vacuum electromagnetic starter comprises a box body, a box door, a reversing knob switch and a test button. The reversing knob switch has three rotation positions: a forward rotation position, a disconnection position and a reverse rotation position. The reversing knob switch comprises a handle and a disk body. Two protrusions are arranged along the radial direction of the disk body. When the handle is rotated to the forward rotation position or the reverse rotation position, the protrusions face the box door, restricting the box door from moving in the direction of the disk body. A slide groove and a slide plate are also arranged on the disk body. When the handle is rotated to the disconnection position, the slide plate can only slide along the slide groove toward the box door, and while restricting the box door from moving in the direction of the disk body, the test button is exposed.
[0009] To further improve the technical solution, a limiting structure is provided on the slide groove, and the limiting structure is used to prevent the slide plate from falling out of the slide groove.
[0010] To further improve the technical solution, a push-pull handle is installed on the skateboard.
[0011] To further improve the technical solution, the disconnection position is arranged in the horizontal direction, and the slide groove is arranged along the horizontal direction.
[0012] To further improve the technical solution, the angles between the positive rotation position and the disconnection position, and between the disconnection position and the reverse position are all 90°.
[0013] After implementing the above technical solution, the beneficial effects produced by the utility model are:
[0014] The interlocking mechanism realizes the interlocking relationship between the reversing knob switch, the test button and the box door, and ensures the safe use of the mine flameproof vacuum electromagnetic starter.
[0015] Compared with the existing interlocking mechanism, the interlocking mechanism has the advantages of simple structure, high reliability, low cost, easy operation and maintenance, etc. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0026] Attached Figure 1 The figure shows a partial schematic diagram of a mining flameproof vacuum electromagnetic starter housing, on which a housing door 2, a reversing switch shaft 3 and a test button 4 are installed. The test button 4 is located below the reversing switch shaft 3, and the reversing switch shaft 3 is used to install a reversing knob switch, which has three positions: forward position, disconnection position and reverse position.
[0027] In this embodiment, with the reversing switch shaft 3 as the center, the disconnection position is set in the horizontal direction, the positive rotation position is set above the reversing switch shaft 3, and the negative rotation position is set below the reversing switch shaft 3. The angles between the positive rotation position and the disconnection position, and between the disconnection position and the reverse position are all 90°. The box door 2 adopts a quick-opening door structure. The box door 2 needs to be translated to the right by 3 cm before it can be rotated outward to open.
[0028] In order to solve the problem in the background technology, the reversing knob switch is mainly composed of a handle 10 and a disk body 5 .
[0029] Refer to the attached Figure 2 , attached Figure 2 The structure diagram of the reversing knob switch is shown. The handle 10 is fixed on the disk body 5, and the disk body 5 is generally in the shape of a racket. Two protrusions 6 are provided along the radial direction of the disk body 5 (with the rotation center as the center of the circle), and the two protrusions 6 are arranged opposite to each other about the center of the disk body 5. In addition, a slide groove 7 and a slide plate 8 are also provided on the disk body 5.
[0030] Refer to the attached Figure 3 and attached Figure 4 , attached Figure 3 The attached Figure 2 Schematic diagram of the structure of the AA section, attached Figure 4 The attached Figure 2 The structural diagram of the BB section is shown in the figure. Figure 3 and attached Figure 4 It can be seen that a push-pull handle 9 is installed on the slide 8, and the slide groove 7 is arranged in the horizontal direction, and the slide 8 can slide along the slide groove 7. In addition, a limit structure with a large end and a small end is also provided on the slide groove 7, and the limit structure can prevent the slide 8 from falling out of the slide groove 7.
[0031] Refer to the attached Figure 5 , attached Figure 5 The structure diagram of the box door 2 when it is open is shown in FIG. Figure 5 It can be seen that when the handle 10 is rotated to the disconnected position, the main power supply in the box is in a power-off state. At this time, the box door 2 can be translated toward the disk body 5. After being translated into place, the box door 2 can be rotated outward to open.
[0032] Refer to the attached Figure 6 , attached Figure 6 The following is a schematic diagram of the switch test. Figure 6 It can be seen that the handle 10 is still in the disconnected position, but the slide plate 8 can slide along the slide groove 7 toward the door 2 to expose the test button 4. At this time, the door 2 is in a closed state, and the switch test can be performed. If the door 2 is in an open state at this time, the slide plate 8 cannot slide toward the door 2, and the test button 4 cannot be exposed, and the switch test cannot be performed.
[0033] Refer to the attached Figure 7 , attached Figure 7 The following is a schematic diagram of the structure of the mining equipment when it is rotating forward. Figure 7 It can be seen that when the handle 10 is rotated to the positive rotation position, a protrusion 6 faces the door 2, restricting the door 2 from moving in the direction of the disk 5, and the door 2 cannot be opened. At the same time, the test button 4 is blocked by the disk 5, and the switch test cannot be performed.
[0034] Refer to the attached Figure 8 , attached Figure 8 The diagram shows the structure of the mining equipment when it is reversed. Figure 8 It can be seen that when the handle 10 is rotated to the negative rotation position, the other protrusion 6 faces the door 2, restricting the door 2 from moving in the direction of the disk 5, and the door 2 cannot be opened. At the same time, the test button 4 is blocked by the disk 5, and the switch test cannot be performed.
[0035] From the above, it can be seen that the interlocking mechanism realizes the interlocking relationship between the reversing knob switch, the test button and the box door, ensuring the safe use of the mine explosion-proof vacuum electromagnetic starter. Compared with the existing interlocking mechanism, the interlocking mechanism has the advantages of simple structure, high reliability, low cost, easy operation and maintenance, etc.
[0036] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the protection scope of the present invention is defined by the attached claims and their equivalents.
