Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment, and in particular relates to an installation, adjustment and maintenance mechanism for a mining flameproof and intrinsically safe frequency converter movement. Background Art

[0002] Mining flameproof and intrinsically safe inverters are widely used in underground mines to control equipment such as explosion-proof hoists, belt conveyors, scraper conveyors, infinite rope winches, underground monkey cars, pump stations, and fans. They not only improve the automation level of coal mine production, but also ensure production safety. At the same time, they achieve energy conservation and emission reduction by optimizing equipment control, which is of great significance to improving coal mine production efficiency and safety.

[0003] With the increasing application and demand, the requirements for increased production and convenient and fast on-site maintenance are becoming more urgent. The inverter movement is the core of the entire machine. How to safely and reliably install the inverter movement in the flameproof enclosure efficiently is the guarantee of product quality and output. Secondly, during the underground maintenance, how to safely and efficiently maintain the movement ensures the safe and timely production of the mine and the control of the supplier's maintenance costs.

[0004] The existing core components of the flameproof and intrinsically safe inverters for mining use adopt modular and standardized designs to achieve universality and mass production, so the core can be regarded as an independent component. However, due to the accumulated errors in the processing and production process, there will be an error of 1-3mm between each core.

[0005] The installation of the movement is more difficult because it has two different installation surfaces that need to be connected to the corresponding fixing surfaces of the flameproof housing through fasteners. The inverter is sometimes installed on the equipment train underground, and the width of the equipment train is limited. According to previous design experience, if the movement is damaged and needs to be repaired, the movement cannot be pulled out of the housing for disassembly and assembly. The control components at the front of the movement can only be removed and replaced. If the components inside are damaged, they can only be repaired by lifting the well, which makes disassembly and maintenance difficult. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides an installation, adjustment and maintenance mechanism for a flameproof and intrinsically safe inverter movement for mining, which can well adjust the error caused by fixing two adjacent surfaces, and does not need to pull the movement out of the housing to adjust the mounting base plate separately, but can adjust the movement and the mounting base plate as a whole, greatly reducing the workload and time. The present invention provides an installation, adjustment and maintenance mechanism for a flameproof and intrinsically safe inverter movement for mining, including:

[0007] A flameproof casing and a movement trolley, wherein the movement trolley is arranged in the flameproof casing, an opening is arranged at the front of the flameproof casing for installing the movement trolley, a back and a bottom of the movement trolley are respectively arranged on two end faces of the flameproof casing, the bottom of the movement trolley is connected to the bottom of the flameproof casing through a mounting base plate, an X-direction adjusting member and a Z-direction adjusting member are arranged on the mounting base plate, and a Y-direction adjusting member is arranged at the bottom of the movement trolley.

[0010] Furthermore, the Z-direction adjustment member includes a plurality of threaded holes arranged on the mounting base plate, and adjustment screws are arranged in the plurality of threaded holes. By adjusting the screwing depth of the adjustment screws, the deviation of the movement trolley in the flameproof casing in the Z direction is adjusted.

[0011] Furthermore, a plurality of rollers are provided on the bottom beam plate of the movement trolley, and the plurality of rollers extend downward from the bottom beam plate. A first slide groove is provided on the mounting bottom plate, and the rollers cooperate with the first slide groove to push the movement trolley into the explosion-proof casing.

[0012] Furthermore, the X-direction adjustment member also includes a plurality of adjustment screws fixedly arranged in the flameproof casing, and the plurality of adjustment screws are distributed on both sides of the casing bottom plate and abut against the casing bottom plate. The position of the casing bottom plate in the X direction is adjusted by adjusting the screws, thereby driving the adjustment movement trolley to adjust the deviation of the X direction in the flameproof casing.

[0013] Furthermore, a heat sink is provided on the back of the movement trolley, and the flameproof casing corresponds to the back of the movement trolley as a casing back plate, a square hole is provided on the casing back plate, the heat sink extends out of the square hole, and is fixedly connected to a heat sink cover plate provided on the square hole.

[0014] The installation, adjustment and maintenance mechanism of the mining explosion-proof and intrinsically safe inverter movement of the present invention also includes: a tool frame, a front flange is provided at the front opening of the explosion-proof shell, the tool frame is fixedly arranged at the front end of the front flange, and a second slide groove is provided on the tool frame so that the movement trolley can be pulled out of the explosion-proof shell and maintained on the tool frame.

[0015] Furthermore, the tooling frame includes a bearing plate, one end of the bearing plate is fixedly connected to the lower portion of the front flange, and a plurality of foot supports are arranged below the bearing plate.

[0016] Furthermore, the tooling frame includes a bearing plate, one end of the bearing plate is fixedly connected to the lower part of the front flange, and the other end of the bearing plate is fixedly connected to the upper part of the front flange via a chain.

[0020] In addition, the tooling frame of the present invention has two application scenarios. The first is that when there is a flat ground in front of the explosion-proof enclosure, a foot support is set on the ground, and the movement trolley is pulled out of the explosion-proof enclosure as a whole and placed on the tooling frame for maintenance. The second is used when the frequency converter is installed on an underground equipment train. Due to the width limitation of the equipment train, generally in this case, there is no flat ground in front of the explosion-proof enclosure. When the front door is opened, the front is suspended in the air, and at this time, there is no ground for the foot support. In this case, the tooling frame is fixedly connected to the explosion-proof shell by a chain, and the movement trolley is pulled out of the explosion-proof enclosure as a whole and placed on the tooling frame for maintenance. Both methods greatly facilitate underground maintenance work.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, the present invention provides a mechanism for installing, adjusting and maintaining a movement of a flameproof and intrinsically safe frequency converter for mining, comprising:

[0034] A flameproof housing 1 and a movement trolley 2, wherein the movement trolley 2 is arranged in the flameproof housing 1, an opening is arranged at the front of the flameproof housing 1 for installing the movement trolley 2, a back and a bottom of the movement trolley 2 are respectively arranged on two end surfaces of the flameproof housing 1, a bottom of the movement trolley 2 is connected to the bottom of the flameproof housing 1 through a mounting base plate 3, an X-direction adjusting member and a Z-direction adjusting member are arranged on the mounting base plate 3, and a Y-direction adjusting member is arranged at the bottom of the movement trolley 2.

[0035] The installation, adjustment and maintenance mechanism of the mine flameproof and intrinsically safe inverter movement of the present invention allows the movement to have an error of 2-3 mm in the six directions of XYZ after being pushed into the flameproof housing by designing the installation base plate and the installation method, thereby reducing the difficulty of machining, facilitating machining and installation.

[0036] like Figures 3 to 6 As shown, the bottom of the movement trolley 2 includes a bottom beam plate 21, the bottom of the flameproof casing 1 includes a casing bottom plate, and the X-direction adjusting member includes 8 X-direction long holes 31 arranged on the mounting bottom plate 3, the 8 X-direction long holes 31 are distributed in two rows and four columns, the 8 X-direction long holes 31 are threadedly connected to the casing bottom plate, and the X-direction long holes 31 are used to adjust the deviation of the movement trolley 2 in the flameproof casing 1 in the X direction.

[0037] The Y-direction adjustment member includes a plurality of Y-direction long holes 22 arranged on the bottom beam plate 21, wherein 7 Y-direction long holes 22 are arranged at the front end of the bottom beam plate 21, and 4 Y-direction long holes 22 are arranged at the rear end of the bottom beam plate 21. The plurality of Y-direction long holes 22 are threadedly connected to the mounting base plate 3, and the Y-direction long holes 22 are used to adjust the Y-direction deviation of the movement trolley 2 in the flameproof casing 1.

[0038] The Z-direction adjustment part includes a plurality of threaded holes arranged on the mounting base plate 3. There is a threaded hole on each of the left and right sides of the X-direction long hole on the mounting base plate 3. Adjustment screws 32 are provided in the 16 threaded holes. The threaded holes can be set to M12. M12x25 hexagonal flat-end set screws are installed in the sixteen M12 threaded holes. By adjusting the screwing depth of the adjustment screws 32, the deviation of the movement trolley 2 in the flameproof casing 1 in the Z direction is adjusted.

[0039] There are 14 rollers 23 on the bottom beam 21 of the movement trolley 2. The 14 rollers 23 extend downward from the bottom beam 21. The 14 rollers 23 are divided into two rows and are arranged on the left and right sides of the bottom beam 21 respectively. A first slide groove 33 is provided on the mounting base 3. The first slide groove 33 is also divided into two left and right rows, corresponding to the two rows of rollers 23. The rollers 23 and the first slide groove 33 cooperate to push the movement trolley 2 into the flameproof casing 1.

[0040] The X-direction adjustment member also includes four adjustment screws 12 fixedly arranged in the flameproof casing 1. The four adjustment screws 12 are distributed on both sides of the casing bottom plate and abut against the casing bottom plate. By adjusting the relative extension lengths of the left and right sides of the screws 12, the left and right positions of the casing bottom plate can be fine-tuned, thereby driving the adjustment of the deviation of the movement trolley 2 in the X direction in the flameproof casing 1.

[0041] A heat sink 24 is provided on the back of the movement trolley 2, and the flameproof housing 1 is a housing back plate 13 corresponding to the back of the movement trolley 2. The housing back plate 13 is provided with a square hole, and the heat sink 24 extends out of the square hole and is fixedly connected to the heat sink cover plate 14 provided on the square hole.

[0042] After the roller 23 at the bottom of the movement trolley 2 enters the left and right first slide grooves 33 on the mounting base plate 3, the movement trolley 2 can be pushed into the explosion-proof housing. After the movement trolley 2 is pushed to the appropriate position, the movement trolley 2 can be adjusted by adjusting the upper X, Y, and Z direction adjustment members. The X-direction adjustment can be made by fine-tuning the mounting base plate 3 with four adjustment screws installed on the front and rear of the housing base plate to drive the movement trolley 2 in the X-direction position. The X-direction position of the movement trolley 2 can also be adjusted by the X-direction long hole 31 on the mounting base plate 3. The Y-direction pushes the movement trolley 2 so that the end face of the heat sink 24 at the rear of the movement trolley 2 is flush with the outer surface of the housing rear plate 13; the Z-direction is adjusted by adjusting the hexagon socket head screw wrench clockwise or counterclockwise to adjust the height of the movement trolley 2 in the Z-direction. After all adjustments are completed, observing from the rear of the shell, the heat sink 24 of the movement car 2 extends out from the square hole of the rear plate 13 of the shell, and the end surfaces of the two faces are flush. The gaps between the upper, lower, left and right four faces of the heat sink 24 and the upper, lower, left and right four faces of the square hole are basically the same, which means that the adjustment is basically in place. At this time, the heat sink cover 14 can be installed, and the mounting holes on the outer circle of the heat sink cover 14 are connected to the threaded holes of the rear plate 13 of the shell, and the mounting holes on the inner circle of the heat sink cover 14 are connected to the threaded holes of the heat sink 24. When all the screws are installed, it means that the movement car 2 is installed in the correct position.

[0043] The installation, adjustment and maintenance mechanism of the mine-use flameproof and intrinsically safe inverter movement of the present invention realizes a mode in which the movement trolley 2 can be adjusted together with the mounting base plate 3 after being pushed into the housing. This is more convenient than the previous method of pushing the movement out of the flameproof housing 1 and then adjusting the mounting base plate 3 after each comparison, greatly improving the installation efficiency and saving manpower.

[0044] The installation, adjustment and maintenance mechanism of the mine-use flameproof and intrinsically safe inverter movement of the present invention can also solve the maintenance problem of the movement trolley at the underground site. Because the movement trolley is an integral component, the installation and disassembly of various structural parts have sequential steps, and the space inside the flameproof shell is limited. The sheet metal parts of the movement structure cannot be disassembled in the flameproof cavity. Therefore, it is necessary to pull the movement trolley out of the flameproof shell as a whole.

[0045] Therefore, the installation, adjustment and maintenance mechanism of the mine-use explosion-proof and intrinsically safe inverter movement of the present invention also includes: a tool frame 4, a front flange 15 is provided at the front opening of the explosion-proof casing 1, the tool frame 4 is fixedly arranged at the front end of the front flange 15, and a second slide groove 41 is provided on the tool frame 4, so that the movement trolley 2 can be pulled out of the explosion-proof casing 1 and maintained on the tool frame 4.

[0046] The present invention designs two usage scenarios according to actual conditions. One is suitable for the situation where there is a flat ground in front of the field flameproof enclosure, such as Figure 1 As shown, the tooling frame 4 includes a bearing plate 42, one end of which is fixedly connected to the lower portion of the front flange 15, and six foot supports 43 are arranged below the bearing plate 42, and the foot supports 43 are threadedly connected to the bearing plate 42, and the height of the entire tooling frame 4 is adjusted by adjusting the screwing depth of the foot supports 43.

[0047] The foot support 43 is square, which is convenient for tightening with an adjustable spanner. The foot support 43 can be made of an M16 external threaded rod, which is screwed into the internal threaded hole of the load-bearing plate 42. The height of the tooling frame 4 is adjusted by adjusting the depth of the foot support 43 screwed into the load-bearing plate 42 with an adjustable spanner until the second slide groove 41 of the load-bearing plate is flush with the first slide groove 33 of the mounting base 3 in the flameproof enclosure 1. At this time, the nut on the foot support 43 is screwed tightly against the bottom surface of the load-bearing plate 42 until it is screwed tightly, that is, the foot support 43 is locked, and the tooling frame 4 is fine-tuned to the appropriate position front and back, left and right, and the long hole at the front end of the tooling frame 4 is fixed with the threaded hole on the lower flange surface of the front flange 15 of the flameproof enclosure 1 with screws, that is, the tooling frame 1 is fixed. At this time, various cables can be removed and the small movement 2 can be pulled out, so that the movement maintenance can be performed outside the flameproof enclosure 1.

[0048] Another method is suitable for the case where the frequency converter is installed on an underground equipment train. Because of the width limitation of the equipment train, in this case, there is generally no flat ground in front of the flameproof enclosure. When the front door is opened, the front is suspended in the air. At this time, the foot support 43 has no ground for support. In this case, the present invention provides another tooling frame, such as Figure 7 As shown, the tooling frame 4 includes a bearing plate 42 , one end of the bearing plate 42 is fixedly connected to the lower portion of the front flange 15 , and the other end of the bearing plate 42 is fixedly connected to the upper portion of the front flange 15 via a chain 44 .

[0049] Specifically, two M12 eye screws are screwed into the front end of the bearing plate 42, and the threaded holes of the front door are installed using the front flange 15. Two M12 eye screws are screwed into the leftmost and rightmost threaded holes, and D-type M10 chain wire rope buckles are installed on the four eye screws. The stainless steel chain is installed in the wire rope buckles on the corresponding sides. The required chain length can be adjusted by inserting the wire rope buckles into the front and rear links of the chain 44, and then the depth of the eye screws can be adjusted for fine-tuning. When the tooling frame 4 is adjusted to be flush with the mounting base plate 3 in the flameproof casing 1, the purpose of pulling the movement out of the casing for maintenance can be achieved.

[0050] In summary, the installation, adjustment and maintenance mechanism of the mining explosion-proof and intrinsically safe inverter movement of the present invention allows an error of 2-3 mm in the six directions of XYZ after the movement is pushed into the explosion-proof casing, through the design of the installation base plate and the installation method, so that the difficulty of machining is not as high as previously required; secondly, the present invention realizes a mode in which the movement can be adjusted together with the installation base plate after being pushed into the casing, which is more convenient than the previous method of adjusting the installation base plate after each comparison after pushing the movement out of the explosion-proof casing, greatly improves the installation efficiency, and saves manpower.

[0051] The present invention also provides a tooling frame that is convenient for core maintenance, and has two usage scenarios. The first one can be applied to most working situations and is simple and convenient to use, and the second one can be applied to working scenarios with special restrictions such as equipment trains. The core maintenance tooling frame of the present invention greatly facilitates underground maintenance work.
