Description

Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to a mine explosion-proof electric actuator with precise adjustment. Background Technique

[0002] A mine explosion-proof electric actuator is a device specifically used in explosive environments such as mine shafts. It uses an electric drive device to control the movement of valves or other mechanical components to achieve the purpose of precise adjustment. At the same time, it has an explosion-proof function and can operate safely in environments where gas or dust may cause explosions.

[0003] Most of the existing mine explosion-proof electric actuators with precise adjustment have a display screen for displaying adjustment data. However, the display screen is mostly directly exposed to the external environment during use, without protecting the display screen. The display screen is easily attached with dust and can also be damaged by bumps, resulting in poor protection effect for the display screen on the mine explosion-proof electric actuator with precise adjustment and a general service life. Therefore, we propose a mine explosion-proof electric actuator with precise adjustment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mine explosion-proof electric actuator with precise adjustment to solve the problems that the display screen exposed to the external environment is easily attached with dust and can also be damaged by bumps, resulting in a general service life of the electric actuator as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mine explosion-proof electric actuator with precise adjustment includes an electric actuator main body. A display screen is provided at the top of the electric actuator main body, and a fixing box is installed at the rear end of the display screen. An adjusting component is provided in the fixing box. The adjusting component includes two connecting sliders. Both of the two connecting sliders are horizontally slidably connected to the front end of the fixing box, and fixing seats are installed on the front end faces of the two connecting sliders. Slots are opened in the fixing seats, and inserting blocks are connected in the slots. Locking holes are opened on both side walls of the inserting blocks, and disassembly and assembly components for fixing the locking holes are provided at both ends of the inner cavity of the fixing seats. Shielding explosion-proof plates are installed at the outer ends of the two inserting blocks.

[0007] Further: The adjusting component further includes a handwheel. The handwheel is located on the right outer wall of the fixing box, and the output end of the handwheel is connected with a bidirectional lead screw. Two threaded blocks are threadedly connected to the bidirectional lead screw. A through groove is opened on the front end face of the fixing box and is arranged in a penetrating manner, and the through groove is slidably connected with the two connecting sliders. The rear ends of the two connecting sliders are respectively connected with the front ends of the two threaded blocks.

[0008] Further: The disassembly and assembly component includes an operating rod that is horizontally slidably connected in the fixing seat, and a clamping block adapted to the locking hole is installed on the surface of the operating rod close to the slot.

[0009] Further: An auxiliary plate is connected to the operating rod, and the auxiliary plate is slidably connected to the inner wall of the fixed seat. A compression spring is sleeved on the outer wall of the operating rod, and the compression spring is located between the outer side of the auxiliary plate and the inner wall of the fixed seat.

[0010] Further: A pull ring is connected to the side of the operating rod away from the clamping block, and an anti-slip rubber sleeve is sleeved on the hand-held end of the pull ring.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By rotating the handwheel on the adjusting component of the present utility model, the bidirectional lead screw can be driven to rotate. After the two thread blocks threadedly connected to the bidirectional lead screw are slidably limited by the through groove and the connecting slider, the shielding explosion-proof plates at the front ends of the two fixed seats can move towards each other or in opposite directions. The shielding explosion-proof plate can shield the display screen, playing a protective role for the display on the precisely adjusted mine explosion-proof electric actuator and preventing the display screen from being damaged; through the sliding of the operating rod on the disassembly and assembly component in the fixed seat and the elasticity of the compression spring, the clamping block can be connected to or disengaged from the locking hole, realizing the fixation and loosening of the insertion block and the insertion slot, achieving the quick disassembly and assembly of the shielding explosion-proof plate and the fixed seat, facilitating the assembly and use by the staff, and improving the work efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment 1:

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a precisely adjustable mine explosion-proof electric actuator, including an electric actuator main body 1, a display screen 2 is provided at the top of the electric actuator main body 1, and a fixed box 3 is installed at the rear end of the display screen 2. An adjusting component is provided in the fixed box 3. The adjusting component includes two groups of connecting sliders 8. The two groups of connecting sliders 8 are both horizontally slidably connected to the front end of the fixed box 3, and fixing seats 10 are installed on the front end faces of the two groups of connecting sliders 8. A slot 11 is opened in the fixing seat 10, and a plug 12 is connected in the slot 11. Locking holes 13 are opened on both side walls of the plug 12. Disassembly and assembly components for fixing the locking holes 13 are provided at both ends of the inner cavity of the fixing seat 10. Shielding explosion-proof plates 4 are installed at the outer ends of the two groups of plugs 12.

[0020] The electric actuator main body 1 is a precisely adjustable mine explosion-proof electric actuator. The display screen 2 is installed on the precisely adjustable mine explosion-proof electric actuator. The display screen 2 is used to display control data. Through the action of the adjusting component, the fixing seats 10 fixedly connected to the front ends of the two groups of connecting sliders 8 can be driven to move in opposite or opposite directions, so that the two groups of shielding explosion-proof plates 4 move in opposite or opposite directions. The two groups of shielding explosion-proof plates 4 can shield the display screen 2 and play a protective role for the display 2 on the precisely adjustable mine explosion-proof electric actuator to avoid damage to the display screen 2. When the display screen 2 is viewed, after the two groups of shielding explosion-proof plates 4 move away from the display screen 2 in opposite directions, the display screen 2 can be viewed and used; the plug 12 is fixedly connected to the shielding explosion-proof plate 4. Through the action of the disassembly and assembly component in the fixing seat 10, the fixing and loosening of the plug 12 and the slot 11 are realized, and the rapid disassembly and assembly of the shielding explosion-proof plate 4 and the fixing seat 10 are realized, which is convenient for the staff to assemble and use and improves work efficiency.

[0021] Among them, preferably, the adjusting component further includes a handwheel 5. The handwheel 5 is located on the right outer wall of the fixed box 3, and the output end of the handwheel 5 is connected to a bidirectional lead screw 6. Two thread blocks 7 are threadedly connected to the bidirectional lead screw 6. A through groove 9 is opened through the front end face of the fixed box 3, and the through groove 9 is slidably connected to the two groups of connecting sliders 8. The rear ends of the two groups of connecting sliders 8 are respectively connected to the front ends of the two groups of thread blocks 7;

[0022] The thread block 7 is fixedly connected to the connecting slider 8. By rotating the handwheel 5, the bidirectional lead screw 6 can be driven to rotate forward or backward. After the two groups of thread blocks 7 threadedly connected to the bidirectional lead screw 6 are slidably limited by the connecting slider 8 through the through groove 9, the shielding explosion-proof plates 4 at the front ends of the two groups of fixing seats 10 can be moved in opposite or opposite directions.

[0023] Preferably, the disassembly and assembly component includes an operating rod 14 that is horizontally slidably connected within the fixed seat 10, and a clamping block 17 adapted to the locking hole 13 is installed on one side of the operating rod 14 close to the slot 11; the operating rod 14 is fixedly connected to the clamping block 17.

[0024] Preferably, an auxiliary plate 15 is connected to the operating rod 14, and the auxiliary plate 15 is slidably connected to the inner wall of the fixed seat 10. A compression spring 16 is sleeved on the outer wall of the operating rod 14, and the compression spring 16 is located between the outer side of the auxiliary plate 15 and the inner wall of the fixed seat 10;

[0025] When installing the shielding explosion-proof plate 4, the two operating rods 14 in each group of fixed seats 10 are pulled in opposite directions. At this time, the two auxiliary plates 15 move outward, the compression spring 16 is compressed, and the clamping block 17 is received at both ends of the inner cavity of the fixed seat 10. At this time, the insertion block 12 on the shielding explosion-proof plate 4 can be connected to the slot 11. When the locking hole 13 is aligned with the clamping block 17, release the operating rod 14, and the compressed compression spring 16 automatically returns to its original position, causing the auxiliary plate 15 to move towards the side of the slot 11, and the clamping block 17 moves and connects with the locking hole 13, thus fixing the position of the insertion block 12 and completing the installation of the shielding explosion-proof plate 4. When disassembling, pull the operating rod 14 outward to disengage the clamping block 17 from the locking hole 13. At this time, after the position of the insertion block 12 is no longer restricted, it can be taken out from the slot 11, that is, the disassembly of the shielding explosion-proof plate 4 is completed.

[0026] Embodiment 2:

[0027] Refer to Figure 3 , the difference between this embodiment and the first embodiment is that a pull ring is connected to the side of the operating rod 14 away from the clamping block 17, and an anti-slip rubber sleeve is sleeved on the hand-held end of the pull ring; the pull ring facilitates the pulling of the operating rod 14, and the anti-slip rubber sleeve plays an anti-slip role to prevent slipping off when holding the pull ring.
