Description

Technical Field

[0001] This utility model relates to the field of mine power supply equipment technology, and in particular to a seismic-resistant installation device for mine power supply equipment. Background Technology

[0002] Mine power supply refers to the power supply device or power supply system that provides electrical energy to various electrical equipment and facilities in coal mines, as well as mine production and safety monitoring systems. It is an important guarantee for safe production in mines, and its reliability and stability are directly related to the normal production and personnel safety of the mine.

[0003] In the mining environment, vibrations are frequently generated underground, such as from mine blasting or machinery operation. If these vibrations are transmitted to the mine power equipment, they may cause deformation of the equipment casing, cracking of solder joints, or loosening of internal components, leading to equipment failure and affecting the normal power supply. At the same time, the mine ground may be uneven. If the mine power equipment is installed at an angle, it will cause uneven stress on the internal components, such as transformer oil level deviation, eccentric operation of cooling fans, and may even cause problems such as poor contact or heat dissipation failure. Therefore, a seismic-resistant installation device for mine power equipment is needed. Utility Model Content

[0004] The main purpose of this utility model is to provide a seismic-resistant installation device for mine power equipment, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anti-seismic installation device for mine power equipment includes two support blocks. A connecting rod is fixedly connected to the front and rear of one end of each support block that is close to each other. An anti-seismic device is fixedly connected to the front and rear of the upper end of each support block. A base plate is fixedly connected to the upper end of the four anti-seismic devices. A mine power supply body is installed in the middle of the upper end of the base plate. A guardrail is fixedly connected to the outer ring of the upper end of the base plate. Rectangular holes are opened at the front and rear of the lower end of each support block. A leveling mechanism is fixedly connected to the inner cavity of each of the four rectangular holes.

[0007] Preferably, the two support blocks are hollow inside.

[0008] Preferably, the seismic device includes two mounting blocks, which are fixedly connected to the lower end of the base plate and the upper end of the support block, respectively. The two mounting blocks are symmetrically distributed vertically. The lower front and rear parts of the lower end of the upper mounting block are fixedly connected to a first fixing rod, and the upper front and rear parts of the upper mounting block are fixedly connected to a second fixing rod. The left and right sides of the outer surfaces of the first fixing rods are rotatably connected to a first connecting rod, and the left and right sides of the outer surfaces of the second fixing rods are rotatably connected to a second connecting rod. A rectangular shell is slidably connected to a portion of the outer surfaces of the two mounting blocks that are close to each other.

[0009] Preferably, movable blocks are fixedly connected to the front end and the middle of the rear end of the rectangular shell, sliders are slidably connected to the inner cavities of the two movable blocks, hydraulic dampers are fixedly connected to the ends of the two sliders that are far apart from each other, damping springs are sleeved on the outer surfaces of the two hydraulic dampers, and the ends of the two hydraulic dampers that are far apart from each other are respectively fixedly connected to the walls of the two movable blocks that are far apart from each other.

[0010] Preferably, the two connecting rods one located at the front and rear are rotatably connected to the left and right ends of the two sliders, respectively, and the two connecting rods two located at the front and rear are rotatably connected to the left and right ends of the two sliders, respectively.

[0011] Preferably, the leveling mechanism includes a limiting shell, which is fixedly connected to the inner cavity of the rectangular hole. A support leg is slidably connected to the inner surface of the limiting shell, and a threaded rod is threadedly connected to the inner surface of the support leg. A knob is fixedly connected to the upper end of the threaded rod.

[0012] Preferably, the outer surface portions of the four threaded rods are rotatably connected to the support block on the same side.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This device is designed with anti-vibration devices to buffer and absorb vibrations caused by factors such as mine blasting or machinery operation around the device. This prevents the mine power supply body from deforming its casing, cracking its solder joints, or loosening its internal components due to vibration, thus ensuring that the mine power supply body can stably supply power to the mine equipment.

[0015] 2. This device, through its designed leveling mechanism, allows workers to adjust the base plate to a horizontal state when the device is on uneven ground. This prevents uneven stress on internal components caused by tilting of the mine power supply body. A stable horizontal state can reduce abnormal wear of internal components of the mine power supply body and ensure the integrity of the mine power supply body. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1, as Figure 1 and Figure 2 As shown, a seismic installation device for mine power equipment includes two support blocks 3. A connecting rod 2 is fixedly connected to the front and rear of one end of the two support blocks 3 that are close to each other. Seismic devices 7 are fixedly connected to the front and rear of the upper ends of the two support blocks 3. A base plate 1 is fixedly connected to the upper ends of the four seismic devices 7. A mine power body 6 is installed in the middle of the upper end of the base plate 1. A guardrail 5 is fixedly connected to the outer ring of the upper end of the base plate 1. Rectangular holes are opened at the front and rear of the lower ends of the two support blocks 3. A leveling mechanism 4 is fixedly connected to the inner cavity of the four rectangular holes.

[0024] Furthermore, the two support blocks 3 are hollow inside.

[0025] Before implementing this device, firstly:

[0026] After moving the device to the designated location next to the mine power supply, place the device on the ground. Because the lower part of the leveling mechanism 4 protrudes from the lower end of the support block 3, the lower part of the leveling mechanism 4 will contact the ground. If the current mine ground is uneven, the workers can use the leveling mechanism 4 to level the support block 3 so that the base plate 1 is in a horizontal state. If the mine power supply body 6 is installed tilted, it may cause uneven stress on the internal components, such as transformer oil level deviation, eccentric operation of the cooling fan, or even poor contact or heat dissipation failure. By adjusting the leveling mechanism 4, the horizontality of the mine power supply body 6 can be controlled within a small range to ensure that it is in an ideal operating state.

[0027] After adjustment, the workers then fix the mine power supply body 6 to the base plate 1 with bolts. Next, the guardrail 5 is fixedly installed on the outer ring of the upper end of the base plate 1 so that the guardrail 5 protects the mine power supply body 6 and prevents workers from directly contacting the mine power supply body 6 when working in the mine, thus ensuring the safety of the workers.

[0028] As described above, after the mine power supply body 6 is installed on the base plate 1, the anti-vibration device 7 can provide anti-vibration protection for the mine power supply body 6. The anti-vibration device 7 absorbs the vibration generated by the low-frequency impact of mechanical operation or the high-frequency vibration of the mine power supply body 6 itself, so as to avoid the deformation of the outer shell, cracking of the solder joints or loosening of internal components caused by severe impact, and reduce the failure of the mine power supply body 6.

[0029] In the above, the hollow design of the support block 3 ensures that the support block 3 has sufficient support force while reducing the weight of the support block 3, making it easier to move the device.

[0030] In Example 2, further, in order to achieve the purpose of earthquake-resistant device 7 providing earthquake protection for the mine power supply body 6, see [reference needed]. Figure 3 and Figure 4 The seismic device 7 includes two mounting blocks 71, which are fixedly connected to the lower end of the base plate 1 and the upper end of the support block 3 respectively. The two mounting blocks 71 are symmetrically distributed vertically. The lower front and rear parts of the lower end of the upper mounting block 71 are fixedly connected to a first fixing rod 72, and the upper front and rear parts of the upper mounting block 71 are fixedly connected to a second fixing rod 74. The left and right sides of the outer surfaces of the first fixing rod 72 are rotatably connected to a first connecting rod 73, and the left and right sides of the outer surfaces of the second fixing rod 74 are rotatably connected to a second connecting rod 75. The outer surfaces of the two mounting blocks 71 are slidably connected to a rectangular shell 791 at a point close to each other.

[0031] Furthermore, movable blocks 76 are fixedly connected to the front end and the middle of the rear end of the rectangular shell 791. Slider blocks 77 are slidably connected to the inner cavity of the two movable blocks 76. Hydraulic dampers 78 are fixedly connected to the ends of the two sliders 77 that are far apart from each other. Damping springs 79 are sleeved on the outer surface of the two hydraulic dampers 78. The ends of the two hydraulic dampers 78 that are far apart from each other are fixedly connected to the walls of the two movable blocks 76 that are far apart from each other.

[0032] Furthermore, the two connecting rods 73 located at the front and rear are rotatably connected to the left and right ends of the two sliders 77, respectively, and the two connecting rods 75 located at the front and rear are rotatably connected to the left and right ends of the two sliders 77, respectively.

[0033] In the above-mentioned scenario, when vibrations occur around the device, such as low-frequency impacts from mine blasting or mechanical operation, the two mounting blocks 71 will float up and down within the rectangular shell 791. As the two mounting blocks 71 float up and down, the connection between the fixing rod 1 72 and the fixing rod 2 74 and the connecting rod 1 73 and the connecting rod 2 75 will cause the connecting rod 1 73 and the connecting rod 2 75 to rotate. The connecting rod 1 73 and the connecting rod 2 75, through their connection with the slider 77, cause the mounting blocks 71 to float up and down, driving the connecting rod 1 73 and the connecting rod 2 75 to rotate up and down. This, in turn, pushes the connecting rod 1 73 and the connecting rod 2 75. The two sliders 77 move to a point further apart, causing them to slide within the cavity of the movable block 76. When the two anti-vibration devices 7 move to a point further apart, they compress the hydraulic damper 78 and the damping spring 79. The damping spring 79 provides elastic buffering and absorbs the generated vibration energy. The hydraulic damper 78 mainly consumes high-frequency vibration kinetic energy, such as the high-frequency vibration of the mine power supply body 6 itself, thereby providing anti-vibration protection for the mine power supply body 6 and ensuring that the mine power supply body 6 stably supplies power to the mine equipment, ensuring that other equipment can work normally.

[0034] Furthermore, in order to achieve the purpose of adjusting the base plate 1 to a horizontal state through the leveling mechanism 4, refer to... Figure 5 The leveling mechanism 4 includes a limiting shell 44, which is fixedly connected to the inner cavity of the rectangular hole. A support leg 43 is slidably connected to the inner surface of the limiting shell 44. A threaded rod 42 is threadedly connected to the inner surface of the support leg 43. A knob 41 is fixedly connected to the upper end of the threaded rod 42.

[0035] Furthermore, the outer surfaces of the four threaded rods 42 are respectively rotatably connected to the support blocks 3 on the same side.

[0036] In the above description, when the device is placed on the ground, the support leg 43 will be in contact with the ground. If the ground is uneven, one support leg 43 will not be in contact with the ground, and the base plate 1 will not be horizontal. At this time, the operator can manually rotate the knob 41 to drive the threaded rod 42 to rotate. When the threaded rod 42 rotates, it will drive the support leg 43 to move downward through the threaded connection with the support leg 43. At the same time, the support leg 43 will be limited by the limiting shell 44, so that the support leg 43 slides in the inner cavity of the limiting shell 44 and moves vertically downward, so that the lower end of the support leg 43 contacts the ground. After adjusting in sequence, the base plate 1 can be adjusted to a horizontal state.
