Description

Technical Field

[0001] This utility model relates to the field of hydraulic technology, specifically to an electromagnetic directional valve for a coal dust removal hydraulic system. Background Technology

[0002] The mining, transportation, and processing of coal generate a large amount of dust, which not only affects the working environment but also harms workers' health. Therefore, coal dust removal systems are being used more and more widely, and the performance and reliability of hydraulic systems, as an important component of dust removal equipment, directly affect the dust removal effect.

[0003] In existing coal dust removal hydraulic systems, electromagnetic directional valves are typically driven by controllers. Over time, these controllers are susceptible to external impacts, which can affect the normal operation of the system and consequently its efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an electromagnetic directional valve for a coal dust removal hydraulic system, in order to solve the problem that the electromagnetic directional valves used in existing coal dust removal hydraulic systems are usually driven by a controller. During long-term use, the controller is easily subjected to external impacts, which over time affects the normal use of the device and thus affects its working efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an electromagnetic directional valve for a coal dust removal hydraulic system, comprising a valve body and a valve head. The valve head is fixedly mounted on the surface of the valve body. A protective structure is provided on the surface of the valve body, including a connecting plate. The surface of the connecting plate is fixedly connected to the surface of the valve body. A groove is formed on the surface of the connecting plate, and the protective plate is slidably connected to the inner wall of the groove. A first bidirectional screw is slidably connected to the inner wall of the groove, and the arc surface of the first bidirectional screw is threadedly connected to the surface of the protective plate. A motor is mounted on the surface of the connecting plate, and the output end of the motor is fixedly connected to one end of the first bidirectional screw. A fixing groove is fixedly connected to the surface of the protective plate, and a connecting block is fixedly connected to the surface of the protective plate. The size of the fixing groove matches the size of the connecting block. The connecting plate provides an installation base for the protective structure, connecting the protective structure to the valve body. The design of the slide groove, protective plate, and first bidirectional screw provides sliding space for the protective plate. The threaded connection between the first bidirectional screw and the protective plate allows the protective plate to move accurately in opposite directions within the slide groove when the first bidirectional screw rotates, thus achieving the protective function for the valve body and valve head. The motor provides power for the rotation of the first bidirectional screw, facilitating the automatic opening and closing of the protective plate. The fixed groove and connecting block create a closed structure between the protective plates, enhancing the protective effect.

[0007] Furthermore, a pad made of rubber is fixedly connected to the surface of the protective plate. The use of rubber in the pad provides cushioning when the protective plate comes into contact with the valve body or other components, preventing damage to the valve body or similar parts.

[0008] Furthermore, a protective pad, made of silicone, is fixedly connected to the surface of the protective plate. The use of silicone in the protective pad further protects the valve body and other components from external influences.

[0009] Furthermore, the valve body surface is provided with a clamping structure, which includes a fixing plate. The surface of the fixing plate is fixedly connected to the surface of the valve body. A groove is formed on the surface of the fixing plate, and a clamping block is slidably connected to the inner wall of the groove. A second bidirectional screw is slidably connected to the inner wall of the groove, and the arc surface of the second bidirectional screw is slidably connected to the surface of the clamping block. A rotating plate is fixedly connected to one end of the second bidirectional screw, and a bolt is slidably connected to the surface of the rotating plate. One end of the bolt is threadedly connected to the surface of the fixing plate. An extension plate is fixedly connected to the surface of the clamping block, and a connecting rod is slidably connected to the surface of the extension plate. The fixing plate provides an installation base for the clamping structure, connecting the clamping structure to the valve body. The groove, clamping block, and second bidirectional screw provide sliding space for the clamping block within the groove. The threaded connection between the second bidirectional screw and the clamping block allows the clamping block to move accurately towards or away from each other within the groove when the second bidirectional screw rotates, thereby achieving the clamping function of the valve body. The rotating plate and bolts allow the operator to easily rotate the second bidirectional screw, while the bolts fix the position of the rotating plate, thereby fixing the position of the clamping block and ensuring clamping stability. The extension plate and connecting rod work together to guide and restrict the movement of the clamping block, ensuring that the clamping block can only move in a straight line.

[0010] Furthermore, a protrusion is fixedly connected to the surface of the clamping block, and a recess is formed on the surface of the clamping block. The size of the protrusion matches the size of the recess. The protrusion and recess serve as positioning and connecting elements when multiple clamping blocks are engaged, improving the integrity and accuracy of the clamping structure.

[0011] Furthermore, a friction pad made of silicone is fixedly connected to the surface of the clamping block. The use of silicone in the friction pad increases the friction between the clamping block and the clamped component, preventing the valve body from sliding during clamping and improving clamping stability.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a protective structure. When protection of the valve body and valve head is required, the motor is activated. The motor's output drives the first bidirectional screw to rotate. Since the first bidirectional screw is threadedly connected to the protective plate, and the protective plate can slide within a groove, the two protective plates move towards or away from each other as the first bidirectional screw rotates. When the protective plates reach the appropriate position, a connecting block on one protective plate can be inserted into a fixed groove on the other, forming a closed structure between the protective plates. The rubber pad provides cushioning when the protective plate contacts the valve body or other components, and the silicone protective pad further protects the valve body and other components from external factors. The connecting plate provides a mounting base for the protective structure, connecting it to the valve body. The groove, protective plates, and first bidirectional screw provide sliding space for the protective plates, and the threaded connection between the first bidirectional screw and the protective plates allows the protective plates to move accurately towards or away from each other within the groove when the first bidirectional screw rotates, thus achieving the protective function for the valve body and valve head. The motor provides power for the rotation of the first bidirectional screw, facilitating the automatic opening and closing of the protective plate. The fixing groove and connecting block create a closed structure between the protective plates, enhancing protection. The rubber pad cushions the protective plate when it contacts the valve body or other components, preventing damage. The silicone protective pad further protects the valve body and other components from external influences. This protective structure also facilitates the protection of the control panel on the valve body surface, minimizing impact damage and extending its lifespan.

[0014] This invention utilizes a clamping structure. When the valve body needs to be fixed in a certain position, the rotating plate is rotated. The rotating plate drives the second bidirectional screw to rotate. Since the second bidirectional screw and the clamping block are threadedly connected, and the clamping block can slide within the groove, while the rotation of the clamping block is restricted by the connecting rod, the two clamping blocks will move towards or away from each other as the second bidirectional screw rotates. When the clamping block moves to the appropriate position, the bolt is screwed into the fixing plate to fix the rotating plate, thereby fixing the position of the clamping block. The protrusions and recesses on the clamping blocks can play a positioning and connecting role when multiple clamping blocks are engaged. The silicone friction pad can increase the friction between the clamping block and the clamped part, improving the stability of clamping. The fixing plate provides an installation base for the clamping structure, connecting the clamping structure to the valve body. The groove, clamping block, and second bidirectional screw provide sliding space for the clamping block within the groove. The threaded connection between the second bidirectional screw and the clamping block allows the clamping block to move accurately towards or away from each other within the groove when the second bidirectional screw rotates, thus achieving the clamping function of the valve body. The rotating plate and bolts facilitate easy rotation of the second bidirectional screw by the operator, while the bolts fix the position of the rotating plate, thereby fixing the position of the clamping block and ensuring clamping stability. The extension plate and connecting rod work together to guide and restrict the movement of the clamping block, ensuring it can only move in a straight line. The protrusions and recesses provide positioning and connection when multiple clamping blocks are engaged, improving the overall integrity and accuracy of the clamping structure. The friction pad, made of silicone, increases the friction between the clamping block and the clamped component, preventing the valve body from slipping during clamping and improving stability. This clamping structure facilitates clamping of wire connections, minimizing bending and damage, further enhancing the device's operational stability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4As shown, this utility model is an electromagnetic directional valve for a coal dust removal hydraulic system, including a valve body 1 and a valve head 2. The valve head 2 is fixedly mounted on the surface of the valve body 1. A protective structure 3 is provided on the surface of the valve body 1. The protective structure 3 includes a connecting plate 31, the surface of which is fixedly connected to the surface of the valve body 1. A groove 32 is formed on the surface of the connecting plate 31, and a protective plate 35 is slidably connected to the inner wall of the groove 32. A first bidirectional screw 33 is slidably connected to the inner wall of the groove 32, and the arc surface of the first bidirectional screw 33 is threadedly connected to the surface of the protective plate 35. A motor 34 is provided on the surface of the connecting plate 31, and the output end of the motor 34 is fixedly connected to one end of the first bidirectional screw 33. A fixing groove 36 and a connecting block 37 are fixedly connected to the surface of the protective plate 35. The size of the fixing groove 36 is adapted to the size of the connecting block 37. The connecting plate 31 provides an installation base for the protective structure 3, connecting the protective structure 3 to the valve body 1. The arrangement of the slide groove 32, the protective plate 35, and the first bidirectional screw 33 enables the slide groove 32 to provide sliding space for the protective plate 35. The threaded connection between the first bidirectional screw 33 and the protective plate 35 allows the protective plate 35 to move accurately towards or away from each other within the slide groove 32 when the first bidirectional screw 33 rotates, thereby achieving the protective function for the valve body 1 and the valve head 2. The motor 34 provides power for the rotation of the first bidirectional screw 33, facilitating the automatic opening and closing operation of the protective plate 35. The fixing groove 36 and the connecting block 37 enable the fixing groove 36 and the connecting block 37 to form a closed structure between the protective plates 35, enhancing the protective effect.

[0025] A pad 38, made of rubber, is fixedly connected to the surface of the protective plate 35. The pad 38 is designed to cushion the valve body 1 or other components when they come into contact with the protective plate 35, preventing damage to the valve body 1 or other parts.

[0026] A protective pad 39, made of silicone, is fixedly connected to the surface of the protective plate 35. The use of silicone material for the protective pad 39 further protects the valve body 1 and other components from external factors.

[0027] The valve body 1 has a clamping structure 4 on its surface. The clamping structure 4 includes a fixing plate 41, the surface of which is fixedly connected to the surface of the valve body 1. A groove 42 is formed on the surface of the fixing plate 41, and a clamping block 44 is slidably connected to the inner wall of the groove 42. A second bidirectional screw 43 is slidably connected to the inner wall of the groove 42, and the arc surface of the second bidirectional screw 43 is slidably connected to the surface of the clamping block 44. A rotating plate 47 is fixedly connected to one end of the second bidirectional screw 43, and a bolt 48 is slidably connected to the surface of the rotating plate 47. One end of the bolt 48 is threadedly connected to the surface of the fixing plate 41. An extension plate 45 is fixedly connected to the surface of the clamping block 44, and a connecting rod 46 is slidably connected to the surface of the extension plate 45. The fixing plate 41 provides an installation base for the clamping structure 4, connecting the clamping structure 4 to the valve body 1. The groove 42, clamping block 44, and second bidirectional screw 43 provide sliding space for the clamping block 44. The threaded connection between the second bidirectional screw 43 and the clamping block 44 allows the clamping block 44 to move accurately towards or away from each other within the groove 42 when the second bidirectional screw 43 rotates, thus achieving the clamping function of the valve body 1. The rotating plate 47 and bolt 48 facilitate the operator's rotation of the second bidirectional screw 43, while the bolt 48 fixes the position of the rotating plate 47, thereby fixing the position of the clamping block 44 and ensuring clamping stability. The extension plate 45 and connecting rod 46 work together to guide and restrict the rotation of the clamping block 44, ensuring that the clamping block 44 can only move in a straight line.

[0028] A protrusion 49 is fixedly connected to the surface of the clamping block 44, and a recess 410 is provided on the surface of the clamping block 44. The size of the protrusion 49 matches the size of the recess 410. The protrusion 49 and the recess 410 are designed to provide positioning and connection when multiple clamping blocks 44 are engaged, thereby improving the integrity and accuracy of the clamping structure 4.

[0029] A friction pad 411 is fixedly connected to the surface of the clamping block 44. The friction pad 411 is made of silicone. The use of silicone material for the friction pad 411 increases the friction between the clamping block 44 and the clamped part, prevents the valve body 1 from sliding during clamping, and improves the stability of clamping.

[0030] When protection of valve body 1 and valve head 2 is required, motor 34 is started. The output end of motor 34 drives the first bidirectional screw 33 to rotate. Since the first bidirectional screw 33 is threadedly connected to the protective plate 35, and the protective plate 35 can slide in the slide groove 32, the two protective plates 35 will move towards or away from each other as the first bidirectional screw 33 rotates. When the protective plate 35 moves to the appropriate position, the connecting block 37 on one protective plate 35 can be inserted into the fixing groove 36 on the other protective plate 35, so that a closed structure is formed between the protective plates 35. The rubber pad 38 can play a buffering role when the protective plate 35 contacts the valve body 1 or other components. The silicone protective pad 39 can further protect the valve body 1 and other components from external factors. The setting of the connecting plate 31 provides an installation base for the protective structure 3, connecting the protective structure 3 to the valve body 1. The arrangement of the slide groove 32, the protective plate 35, and the first bidirectional screw 33 provides sliding space for the protective plate 35 through the slide groove 32. The threaded connection between the first bidirectional screw 33 and the protective plate 35 allows the protective plate 35 to move accurately towards or away from each other within the slide groove 32 when the first bidirectional screw 33 rotates, thereby achieving the protective function for the valve body 1 and the valve head 2. The motor 34 provides power for the rotation of the first bidirectional screw 33, facilitating the automatic opening and closing operation of the protective plate 35. The fixing groove 36 and the connecting block 37 enable the protective plate 35 to form a closed structure, enhancing the protective effect. The pad 38, made of rubber, acts as a buffer when the protective plate 35 contacts the valve body 1 or other components, preventing damage to the valve body 1, etc., caused by the protective plate 35. The protective pad 39 is made of silicone material, which further protects the valve body 1 and other components from external factors. By setting the protective structure 3, it is convenient to protect the control panel on the surface of the valve body 1, minimize the impact on the control panel on the surface of the valve body 1, and further extend the service life of the control panel on the surface of the valve body 1.

[0031] When the valve body 1 needs to be fixed in a certain position using the clamping structure 4, the rotating plate 47 is rotated. The rotating plate 47 drives the second bidirectional screw 43 to rotate. Since the second bidirectional screw 43 and the clamping block 44 are threadedly connected, and the clamping block 44 can slide in the groove 42, while the clamping block 44 is restricted from rotation by the connecting rod 46, the two clamping blocks 44 will move towards or away from each other as the second bidirectional screw 43 rotates. When the clamping block 44 moves to the appropriate position, the bolt 48 is screwed into the fixing plate 41 to fix the rotating plate 47, thereby fixing the position of the clamping block 44. The protrusion 49 and the recess 410 on the clamping block 44 can play a positioning and connecting role when multiple clamping blocks 44 are engaged. The silicone friction pad 411 can increase the friction between the clamping block 44 and the clamped part, improving the stability of clamping. The setting of the fixing plate 41 provides an installation base for the clamping structure 4, connecting the clamping structure 4 to the valve body 1. The groove 42, clamping block 44, and second bidirectional screw 43 provide sliding space for the clamping block 44. The threaded connection between the second bidirectional screw 43 and the clamping block 44 allows the clamping block 44 to move accurately towards or away from each other within the groove 42 when the second bidirectional screw 43 rotates, thus achieving the clamping function of the valve body 1. The rotating plate 47 and bolt 48 facilitate the operator's rotation of the second bidirectional screw 43, while the bolt 48 fixes the position of the rotating plate 47, thereby fixing the position of the clamping block 44 and ensuring clamping stability. The extension plate 45 and connecting rod 46 guide and restrict the rotation of the clamping block 44, ensuring that the clamping block 44 can only move linearly. The protrusion 49 and recess 410 provide positioning and connection when multiple clamping blocks 44 are engaged, improving the integrity and accuracy of the clamping structure 4. The friction pad 411 is made of silicone material, which increases the friction between the clamping block 44 and the clamped part, prevents the valve body 1 from sliding during clamping, and improves the stability of clamping. By setting the clamping structure 4, it is convenient to clamp the wire connection, minimizes the bending and damage of the wire connection, and further improves the working stability of the device.
