Description

Technical Field

[0001] This invention relates to the field of coal mining machine technology, and more specifically, to the structure of the electrical control unit of a coal mining machine and the coal mining machine itself. Background Technology

[0002] In existing technologies, coal mining machines need to operate deep underground. The electrical control boxes of large coal mining machines are often large in size and operate at high temperatures due to their high power. Therefore, problems with the electrical control box during underground maintenance and repairs significantly increase the difficulty of repairs. The large size of the control box also leads to a substantial amount of disassembly work for workers, severely impacting the efficiency of the coal mining machine and increasing the workload of maintenance personnel. Furthermore, if a problem occurs with the control box's components, the entire control box and its associated equipment must be replaced, increasing maintenance costs.

[0003] Therefore, how to propose a structure for the electrical control unit of a coal mining machine that can reduce the maintenance cost of the electrical control box and greatly reduce its temperature has become an urgent problem to be solved. Summary of the Invention

[0004] The first objective of this invention is to provide a structure for the electrical control unit of a coal mining machine.

[0005] The second objective of this invention is to provide a coal mining machine.

[0006] In view of the above, the first aspect of the present invention provides an electrical control unit structure for a coal mining machine. The electrical control unit structure includes: a cabinet with a mounting cavity formed inside; an electrical control box that can be pulled out of the mounting cavity; and a cooling water channel located outside the electrical control box.

[0007] In this technical solution, the electrical control unit structure of the coal mining machine includes a cabinet, an electrical control box, and cooling water channels. The cabinet contains an installation cavity. The electrical control box can be pulled in and out of the installation cavity. The cooling water channels are located outside the electrical control box. By placing the cooling water channels on the electrical control box, the temperature of the electrical control box can be directly reduced. Furthermore, since the cooling water channels are located on the electrical control box, they can be pulled in and out of the cabinet along with the electrical control box. The integrated structure of the cooling water channels and the electrical control box allows for simultaneous improvements to the cooling water channels when modifying the electrical control box, bypassing the cabinet and greatly reducing the difficulty of modifying the coal mining machine. Moreover, since the cabinet and electrical control box appear as separate structures, the difficulty of transporting and installing the electrical control box of the coal mining machine is reduced. In particular, compared to the integrated design of the cabinet and left and right traction units, the weight and length of the individual cabinet are significantly reduced, making it easier to assemble, replace and maintain the coal mining machine underground.

[0008] In some possible technical solutions, the cooling water channels include: a first cooling water channel disposed on the top plate of the electrical control box; and / or a second cooling water channel disposed on the bottom plate of the electrical control box; and / or a third cooling water channel disposed on the side plate of the electrical control box.

[0009] In this technical solution, a first cooling water channel, a second cooling water channel, and a third cooling water channel are respectively arranged on three sides of the electrical control box, or cooling water channels can be arranged on at least one of the three sides of the electrical control box. The cooling water channels can be distributed as needed, and the number of cooling water channels can be reduced or increased while ensuring cooling requirements are met. Since the cooling water channels are directly located on the electrical control box, the distance between the cooling water channels and the electrical control box is closer, resulting in better cooling effect. At the same time, by setting three cooling water channels, the heat dissipation effect is better, and it will not affect the structural strength of the electrical control box. Furthermore, the three cooling water channels can surround the heat-generating areas of the electrical control box. The cooling water channels can also be set in different locations on the electrical control box as needed.

[0010] In some possible technical solutions, the electrical control unit structure of the coal mining machine also includes multiple first bolts. Multiple bolt holes are provided on the top plate of the cabinet. The first bolts can pass through these bolt holes and abut against the electrical control box.

[0011] In this technical solution, the electrical control unit structure of the coal mining machine also includes multiple first bolts. Multiple bolt holes are provided on the top plate of the cabinet. The first bolts can pass through the bolt holes and abut against the electrical control box, thereby limiting the position of the electrical control box and protecting the second cooling water channel located on the top plate of the electrical control box. Furthermore, the abutment between the first bolts and the electrical control box provides reverse support to the top plate of the cabinet, increasing its load-bearing capacity. The staggered positions of the first bolts and the cooling water channel prevent them from interfering with the cooling water channel and thus prevent cracking.

[0012] In some possible technical solutions, the electrical control unit structure of the coal mining machine also includes: multiple second bolts, which are installed between the side plate and the cabinet of the electrical control box when the electrical control box is installed in the mounting cavity, for fixing the electrical control box.

[0013] In this technical solution, the electrical control unit structure of the coal mining machine also includes: multiple second bolts. When the electrical control box is installed in the mounting cavity, the second bolts are installed between the side plate of the electrical control box and the cabinet to fix the electrical control box and the cabinet. This prevents the electrical control box from moving left and right in the cabinet and also protects the third cooling water channel installed on the side plate of the electrical control box.

[0014] In some possible technical solutions, the electrical control unit structure of the coal mining machine also includes: multiple third bolts. When the electrical control box is installed in the mounting cavity, the third bolts are installed between the bottom plate of the electrical control box and the cabinet to fix the electrical control box and the cabinet. Together with the first bolt, they can prevent the electrical control box from moving up and down in the cabinet, and at the same time protect the second cooling water channel installed on the bottom plate of the electrical control box.

[0015] In this technical solution, the electrical control unit structure of the coal mining machine also includes: multiple third bolts. When the electrical control box is installed in the mounting cavity, the third bolts are installed between the bottom plate of the electrical control box and the cabinet to fix the electrical control box.

[0016] In some possible technical solutions, the electrical control box also includes: multiple handles, located on the front side of the electrical control box, for controlling the electrical control box to be pulled out and out of the installation cavity.

[0017] In some possible technical solutions, the coal mining machine includes: two traction units located on both sides of the electrical control unit structure; multiple tie rods, with both ends of the tie rods fixed to the two traction units respectively; and a cabinet including: multiple tie rod slots distributed on the top and bottom surfaces of the electrical control unit structure. The multiple tie rods are respectively installed within the multiple tie rod slots to fix the top surface of the electrical control unit structure between the two traction units.

[0018] In this technical solution, the coal mining machine includes two traction units and multiple tie rods. The two traction units are located on both sides of the electrical control unit structure, and they can fix the electrical control unit structure and install it onto the coal mining machine. The cabinet includes multiple tie rod slots distributed on the top and bottom surfaces of the electrical control unit structure. Multiple tie rods are respectively installed in the multiple tie rod slots to fix the top surface of the electrical control unit structure between the two traction units. Since the two ends of the tie rods are fixed to the two traction units respectively, and the tie rod portions are located in the tie rod slots, by adjusting the fixed positions of the two ends of the tie rods in the traction units, the traction units and the electrical control unit structure can be tightly fitted together to form a whole, and the multiple tie rod slots can prevent the electrical control unit structure from rotating relative to the traction units.

[0019] In some possible technical solutions, the coal mining machine also includes: at least two pins for fixing the traction unit and electrical control unit structure. The cabinet also includes: at least two grooves, with pins disposed within the grooves for fixing the traction unit and electrical control unit structure.

[0020] In this technical solution, the coal mining machine also includes at least two pins for fixing the traction unit and the electrical control unit structure. The cabinet also includes at least two grooves, with the pins positioned within these grooves to fix the traction unit and the electrical control unit structure. When the electrical control unit structure is engaged with the traction unit via a pull rod, the pins are positioned at the contact surface between the electrical control unit structure and the traction unit, and within the grooves of the cabinet. This pin configuration restricts the position of the electrical control unit structure, preventing it from shifting vertically or horizontally relative to the traction unit. Specifically, the pins can be fixedly mounted on the traction unit, or the traction unit can have pin holes corresponding to the grooves, allowing the pins to pass through the pin holes and be inserted into the grooves.

[0021] In some possible technical solutions, the coal mining machine includes: a cable connected to the electrical control box. The cabinet includes: a circuit through-hole, located on the side panel of the cabinet, through which the cable passes to connect to the electrical control box.

[0022] In this technical solution, the coal mining machine also includes: a cable connected to the electrical control box. The cabinet also includes: a circuit through-hole, located on the side plate, through which the cable passes, enabling the connection between the electrical control box and other circuits of the coal mining machine.

[0023] In a second aspect of the invention, a coal mining machine is provided, including an electrical control unit structure as described in the first aspect.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] An embodiment of the first aspect of the present invention provides an electrical control unit structure 10 for a coal mining machine 1, such as... Figures 1 to 7 As shown, the electrical control unit structure 10 of the coal mining machine 1 includes: a cabinet 11, an electrical control box 12, and a cooling water channel 13. The cabinet 11 has an installation cavity 115 formed inside. The electrical control box 12 can be pulled in and out of the installation cavity 115. The cooling water channel 13 is located outside the electrical control box 12.

[0039] In this embodiment, such as Figures 1 to 7 As shown, the electrical control unit structure 10 of the coal mining machine 1 is used for the coal mining machine 1, such as... Figure 1 and Figure 2As shown, the electrical control unit structure 10 of the coal mining machine 1 includes: a cabinet 11, an electrical control box 12, and a cooling water channel 13. The cabinet 11 has an installation cavity 115. The electrical control box 12 can be pulled in and out of the installation cavity 115. The cooling water channel 13 is located outside the electrical control box 12. By placing the cooling water channel 13 on the electrical control box 12, the temperature of the electrical control box 12 can be directly reduced. Furthermore, since the cooling water channel 13 is located on the electrical control box 12, it can be pulled in and out of the cabinet 11 along with the electrical control box 12. The integrated structure of the cooling water channel 13 and the electrical control box 12 allows for simultaneous improvements to the cooling water channel 13 when modifying the electrical control box 12, bypassing the cabinet 11 and greatly reducing the difficulty of modifying the coal mining machine 1. Furthermore, the cabinet 11 and the electrical control box 12 are both separate structures, which reduces the difficulty of transporting and installing the cabinet 11 when installing the electrical control box 12 of the coal mining machine 1. In particular, compared with the scheme of setting the cabinet 11 and the left and right traction units 2 as a whole, the weight and length of the separate cabinet 11 are significantly reduced, which is more conducive to the assembly, replacement and maintenance of the coal mining machine 1 underground.

[0040] In some possible embodiments, the cooling water channel 13 includes: a first cooling water channel 131 disposed on the top plate of the electrical control box 12; and / or a second cooling water channel 132 disposed on the bottom plate of the electrical control box 12; and / or a third cooling water channel 133 disposed on the side plate of the electrical control box 12.

[0041] In this embodiment, such as Figure 4 and Figure 6 As shown, a first cooling water channel 131, a second cooling water channel 132, and a third cooling water channel 133 are respectively arranged on three sides of the electrical control box 12. Alternatively, a cooling water channel 13 can be arranged on at least one of the three sides of the electrical control box 12. The cooling water channels 13 can be distributed as needed, and the number of cooling water channels 13 can be reduced or increased while ensuring cooling requirements. Since the cooling water channels 13 are directly located on the electrical control box 12, the distance between the cooling water channels 13 and the electrical control box 12 is closer, resulting in better cooling effect. At the same time, by setting three cooling water channels 13, the heat dissipation effect is better, and it will not affect the structural strength of the electrical control box 12. Furthermore, the three cooling water channels 13 can surround the heat-generating areas of the electrical control box 12. The cooling water channels 13 can also be arranged in different positions on the electrical control box 12 as needed.

[0042] In some possible embodiments, the electrical control unit structure 10 of the coal mining machine 1 also includes a plurality of first bolts 14. A plurality of bolt holes 111 are provided on the top plate of the cabinet 11. The first bolts 14 can pass through the bolt holes 111 and abut against the electrical control box 12.

[0043] In this embodiment, such as Figure 2 and Figure 3As shown, the electrical control unit structure 10 of the coal mining machine 1 also includes multiple first bolts 14. Multiple bolt holes 111 are provided on the top plate of the cabinet 11. The first bolts 14 can pass through the bolt holes 111 and abut against the electrical control box 12, thereby limiting the position of the electrical control box 12 and protecting the second cooling water channel 132 located on the top plate of the electrical control box 12. Furthermore, the abutment between the first bolts 14 and the electrical control box 12 provides reverse support to the top plate of the cabinet 11, increasing the load-bearing strength of the top plate of the cabinet 11. The staggered positions of the first bolts 14 and the cooling water channel 13 prevent them from affecting the cooling water channel 13 and thus prevent cracking of the cooling water channel 13.

[0044] In some possible embodiments, the electrical control unit structure 10 of the coal mining machine 1 further includes a plurality of second bolts 15, which are disposed between the side plate of the electrical control box 12 and the cabinet 11 when the electrical control box 12 is disposed in the mounting cavity 115, for fixing the electrical control box 12.

[0045] In this embodiment, the electrical control unit structure 10 of the coal mining machine 1 further includes: a plurality of second bolts 15. When the electrical control box 12 is installed in the mounting cavity 115, the second bolts 15 are installed between the side plate of the electrical control box 12 and the cabinet 11 to fix the electrical control box 12 and the cabinet 11. This can prevent the electrical control box 12 from moving left and right in the cabinet 11, and at the same time protect the third cooling water channel 133 installed on the side plate of the electrical control box 12.

[0046] In some possible embodiments, the electrical control unit structure 10 of the coal mining machine 1 further includes a plurality of third bolts 16, which are arranged between the bottom plate of the electrical control box 12 and the cabinet 11 when the electrical control box 12 is installed in the mounting cavity 115, for fixing the electrical control box 12.

[0047] In this embodiment, the electrical control unit structure 10 of the coal mining machine 1 further includes: a plurality of third bolts 16. When the electrical control box 12 is installed in the mounting cavity 115, the third bolts 16 are installed between the bottom plate of the electrical control box 12 and the cabinet 11 to fix the electrical control box 12 and the cabinet 11. In conjunction with the first bolts 14, they can prevent the electrical control box 12 from moving up and down in the cabinet 11, and at the same time protect the second cooling water channel 132 installed on the bottom plate of the electrical control box 12.

[0048] In some possible embodiments, such as Figure 5 As shown, the electrical control box 12 includes multiple handles 17, which are located on the front side of the electrical control box 12 and are used to control the electrical control box 12 to be pulled out of the mounting cavity 115.

The multiple tie rods 3 are respectively disposed in the multiple tie rod slots 112, used to fix the top surface of the electrical control unit structure 10 between the two traction units 2.

[0050] In this embodiment, the coal mining machine 1 includes two traction units 2 and multiple tie rods 3. The two traction units 2 are located on both sides of the electrical control unit structure 10, and can fix the electrical control unit structure 10 and install it onto the coal mining machine 1. The cabinet 11 includes multiple tie rod slots 112, distributed on the top and bottom surfaces of the electrical control unit structure 10. Multiple tie rods 3 are respectively disposed within the multiple tie rod slots 112, used to fix the top surface of the electrical control unit structure 10 between the two traction units 2. Since both ends of the tie rods 3 are fixed to the two traction units 2 respectively, and a portion of the tie rods 3 is disposed within the tie rod slots 112, by adjusting the fixed positions of the two ends of the tie rods 3 in the traction units 2, the traction units 2 and the electrical control unit structure 10 can be tightly fitted together to form a whole, and the multiple tie rod slots 112 can prevent the electrical control unit structure 10 from rotating relative to the traction units 2.

The cabinet 11 also includes at least two grooves 113, in which the pins 4 are disposed for fixing the traction unit 2 and the electrical control unit structure 10. When the electrical control unit structure 10 is engaged with the traction unit 2 via the pull rod 3, the pins 4 are positioned at the contact surface between the electrical control unit structure 10 and the traction unit 2, and are also positioned within the grooves 113 of the cabinet 11. This allows the pins 4 to restrict the position of the electrical control unit structure 10, preventing it from shifting vertically or horizontally relative to the traction unit 2. Specifically, the pins 4 can be fixedly disposed on the traction unit 2, or the traction unit 2 can have pin holes corresponding to the grooves 113, allowing the pins 4 to pass through the pin holes and be inserted into the grooves 113.
