[0002] With increasing environmental awareness and increasingly stringent environmental regulations, the demand for dust removal equipment in the coal industry is constantly growing. As a crucial component of dust removal equipment, the performance and reliability of the hydraulic system directly affect the dust removal effect and the normal operation of the equipment.

[0003] The hydraulic hose structure of existing coal dust removal hydraulic systems often has clamping devices that make it difficult to adjust the clamping plates. When clamping pipe connections of different sizes is required, it is often difficult to adjust quickly. Over time, this affects the normal use of the device and consequently its working efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic hose structure for a coal dust removal hydraulic system, in order to solve the problem that the clamping device on the existing hydraulic hose structure of the coal dust removal hydraulic system is often inconvenient to adjust the clamping plate. When it is necessary to clamp the connection of pipes of different sizes, it is often inconvenient to adjust quickly. Over time, this affects the normal use of the device and thus affects the working efficiency of the device.

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

[0006] This utility model relates to a hydraulic hose structure for a coal dust removal hydraulic system, comprising a pipe body and a circular block. The circular block is fixedly connected to the surface of the pipe body, and an adjustment structure is provided on the surface of the circular block. The adjustment structure includes a sliding groove, with a recessed groove on the inner wall of the sliding groove. A slider is slidably connected to the inner wall of the recessed groove. A fixing plate is fixedly connected to the surface of the slider, and a screw is slidably connected to the surface of the fixing plate. One end of the screw is threadedly connected to the surface of the circular block. A sliding rod is slidably connected to the surface of the slider, and a fixing block is fixedly connected to one end of the sliding rod. A long strip plate is rotatably connected to the surface of the fixing block, and a disc is fixedly connected to the surface of the long strip plate. The sliding groove provides space for partial movement of the slider, allowing it to slide in a certain direction on the surface of the circular block. The recessed groove limits the range of movement of the slider and provides installation space for it, forming an adjustable structure together with the slider, connecting rod, spring, and other components. The slider is a key moving component in the adjustment structure; through its connection with the screw, sliding rod, and other components, its movement within the recessed groove can drive the position adjustment of other components. The fixed plate is positioned to fix itself to the surface of the slider, providing a point for the screw to pass through and connect threadedly. The screw's threaded connection to the circular block allows for fixing or adjusting the slider's position. The screw, through its threaded connection, is used to fix the slider's position. Rotating the screw allows for precise adjustment of the slider's position relative to the circular block, thereby adjusting the position of other components connected to the slider. The sliding rod is slidably connected to the slider, with one end connected to the fixed block, transmitting the slider's movement so that its movement drives the movement of the fixed block and its connected components. The fixed block provides a position for the rotational connection of the long plate, converting the sliding rod's movement into the long plate's rotational movement. The long plate is rotatably connected to the fixed block at one end, with a disc fixedly connected to its surface. The position and orientation of the disc can be adjusted by the slider and sliding rod. The disc's position and orientation can be adjusted via an adjustable structure, potentially for connecting with other components, blocking, or providing some form of adjustment.

[0007] Furthermore, a connecting rod is fixedly connected to the inner wall of the groove, and the arc surface of the connecting rod is slidably connected to the surface of the slider. The connecting rod serves to guide and limit the slider, ensuring stable sliding within the groove and preventing the slider from detaching from the groove or shifting during sliding.

[0008] Furthermore, a spring is fitted onto the arcuate surface of the connecting rod. One end of the spring is fixedly connected to the surface of the slider, and the other end is fixedly connected to the inner wall of the groove. This spring design allows it to fit over the arcuate surface of the connecting rod, with one end fixed to the slider surface and the other end fixed to the inner wall of the groove. When the screw is released, it provides an elastic restoring force to the slider, enabling it to return to its initial position under a certain external force or automatically adjust its position within a certain range.

[0009] Furthermore, the surface of the slider is provided with a clamping structure, which includes a square groove. A movable block is slidably connected to the inner wall of the square groove. The surface of the movable block is fixedly connected to the arc surface of the slide rod. A stop block is fixedly connected to one end of the slide rod, and a clamping plate is fixedly connected to the surface of the movable block. The square groove provides sliding space for the movable block and restricts its sliding direction, allowing it to slide linearly only within the square groove. The movable block, which slides within the square groove and is fixedly connected to the slide rod and clamping plate, is the intermediate component that transmits the movement of the slide rod to the clamping plate. The stop block, fixed to one end of the slide rod, prevents the movable block from slipping off, ensuring the integrity of the clamping structure. The clamping plate, fixed to the surface of the movable block, moves closer to or away from the object to be clamped as the movable block moves, and is the component that directly contacts the object being clamped.

[0010] Furthermore, a clamping block is fixedly connected to the surface of the clamping plate, and the clamping block has a rectangular cross-section. The clamping block is fixed to the surface of the clamping plate, and its rectangular cross-section may increase the contact area between the clamping plate and the clamped item or provide better clamping shape adaptability, thereby improving clamping stability.

[0011] Furthermore, a pad made of rubber is fixedly connected to the surface of the clamping plate. The pad, made of rubber, is fixed to the surface of the clamping plate. Rubber has elasticity and friction, which increases the friction between the clamping plate and the clamped item, while preventing damage to the item.

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

[0013] This invention, through the adjustment of its structure, firstly, fixes a circular block to the surface of the tube body. A groove is formed on the surface of the circular block, and a recess is formed on the inner wall of the groove. A connecting rod is installed on the inner wall of the recess, and a spring is fitted onto it. A slider is placed in the recess, and the arc surface of the slider slides along the connecting rod. One end of the spring is fixed to the surface of the slider, and the other end is fixed to the inner wall of the recess. A fixing plate is fixed to the surface of the slider, and a screw is passed through the surface of the fixing plate. Then, one end of the screw is threaded to the surface of the circular block. A sliding rod is slidably connected to the surface of the slider, and one end of the sliding rod is fixedly connected to a fixing block. A long strip plate is rotatably connected to the surface of the fixing block, and a disc is fixedly connected to the surface of the long strip plate. By rotating the screw, the position of the slider in the recess can be adjusted. Since the slider is connected to the sliding rod, the position of the disc can also be adjusted. When the screw is tightened, the position of the slider is fixed, and the position of the disc is also fixed. When the screw is loosened, the slider can slide in the recess under the action of the spring or under the push of an external force, thereby driving the disc to adjust its position. The groove provides space for partial movement of the slider, allowing the slider to slide in a certain direction on the surface of the circular block. The groove design limits the slider's range of motion and provides installation space, forming an adjustable structure together with the slider, connecting rod, spring, and other components. The slider is a key moving part in the adjustment structure; its movement within the groove, connected to the screw and slide rod, drives the position adjustment of other components. The fixing plate is fixed to the slider surface, providing a point for the screw to pass through and connect threadedly. The screw's threaded connection to the circular block allows for fixing or adjusting the slider's position. The screw, through its threaded connection, fixes the slider's position. Rotating the screw precisely adjusts the slider's position relative to the circular block, thereby adjusting the position of other components connected to the slider. The slide rod is slidably connected to the slider, with one end connected to the fixing block, transmitting the slider's movement so that its movement drives the movement of the fixing block and its connected components. The fixing block provides a point for rotational connection to the long plate, converting the slide rod's movement into the long plate's rotational movement. The elongated plate is designed to rotatably connect to a fixed block at one end, with a disc fixedly attached to its surface. The position and orientation of the disc can be adjusted via a slider and a sliding rod. The disc's position and orientation can be adjusted through an adjustable structure, potentially for connecting with other components, blocking, or providing some form of adjustment. The connecting rod guides and limits the slider, ensuring stable sliding within the groove and preventing it from detaching or shifting during movement. A spring is fitted onto the arcuate surface of the connecting rod, with one end fixedly connected to the slider surface and the other end fixedly connected to the inner wall of the groove.When the screw is released, it provides elastic restoring force to the slider, enabling the slider to return to its initial position under a certain external force or automatically adjust its position within a certain range. By setting an adjustment structure, it is convenient to adjust the clamping plate, minimizing the inconvenience of adjusting pipe joints of different sizes, and further improving the ease of operation of the device.

[0014] This invention utilizes a clamping structure with a square groove on the surface of the slider. A movable block is placed into this groove and can slide within it. The movable block is fixedly connected to the arc surface of a sliding rod, and a stop block is fixedly connected to one end of the sliding rod to prevent the movable block from slipping off. A clamping plate is fixedly connected to the surface of the movable block, and a clamping block and a pad are fixedly connected to the surface of the clamping plate. When an item needs to be clamped, pushing the disc rotates the long plate, which in turn moves the sliding rod, which in turn moves the clamping plate. The movable block slides within the square groove, bringing the clamping plate closer to the item to be clamped. The clamping block and pad then contact the item, and the friction between them clamps and pads clamps the item. The square groove provides sliding space for the movable block and restricts its sliding direction, ensuring it can only slide in a straight line within the groove. The movable block, fixedly connected to the sliding rod and clamping plate, is the intermediate component that transmits the movement of the sliding rod to the clamping plate. The stop block is fixed to one end of the slide bar to prevent the moving block from slipping off, ensuring the integrity of the clamping structure. The clamping plate is fixed to the surface of the moving block, moving it closer to or away from the object to be clamped; it is the component that directly contacts the clamped object. The clamping block, fixed to the surface of the clamping plate, has a rectangular cross-section, which may increase the contact area between the clamping plate and the clamped object or provide better clamping shape adaptability, improving clamping stability. The pad, made of rubber, is fixed to the surface of the clamping plate. Rubber has a certain elasticity and friction, which increases the friction between the clamping plate and the clamped object while preventing damage to the object. This clamping structure facilitates clamping work at pipe connections, minimizing instability at pipe connections and further improving the operational stability of the device.

[0025] A connecting rod 39 is fixedly connected to the inner wall of the groove 36, and the arc surface of the connecting rod 39 is slidably connected to the surface of the slider 34. The connecting rod 39 serves to guide and limit the slider 34, ensuring that the slider 34 slides stably within the groove 36 and preventing the slider 34 from detaching from the groove 36 or shifting during the sliding process.

[0026] A spring 310 is fitted onto the arc surface of the connecting rod 39. One end of the spring 310 is fixedly connected to the surface of the slider 34, and the other end is fixedly connected to the inner wall of the groove 36. The spring 310 fits snugly onto the arc surface of the connecting rod 39, with one end fixedly connected to the surface of the slider 34 and the other end fixedly connected to the inner wall of the groove 36. When the screw 38 is released, it provides an elastic restoring force to the slider 34, allowing the slider 34 to return to its initial position under a certain external force or automatically adjust its position within a certain range.

[0027] The surface of the slider 34 is provided with a clamping structure 4, which includes a square groove 46. A movable block 42 is slidably connected to the inner wall of the square groove 46. The surface of the movable block 42 is fixedly connected to the arc surface of the slide rod 33. A stop block 43 is fixedly connected to one end of the slide rod 33, and a clamping plate 41 is fixedly connected to the surface of the movable block 42. The square groove 46 provides sliding space for the movable block 42, restricting its sliding direction and ensuring it can only slide linearly within the square groove 46. The movable block 42 slides within the square groove 46 and is fixedly connected to the slide rod 33 and clamping plate 41, serving as an intermediate component that transmits the movement of the slide rod 33 to the clamping plate 41. The stop block 43 is fixed to one end of the slide rod 33 to prevent the movable block 42 from slipping off, ensuring the integrity of the clamping structure 4. The clamping plate 41 is fixed to the surface of the moving block 42. The moving block 42 moves closer to or away from the item to be clamped, and it is a component that directly contacts the item being clamped.

[0028] A clamping block 44 is fixedly connected to the surface of the clamping plate 41. The clamping block 44 has a rectangular cross-section. The clamping block 44 is fixed to the surface of the clamping plate 41. The rectangular cross-section may increase the contact area between the clamping plate 41 and the clamped item or provide better clamping shape adaptability, thereby improving clamping stability.

[0029] A pad 45, made of rubber, is fixedly connected to the surface of the clamping plate 41. The pad 45, made of rubber, is fixed to the surface of the clamping plate 41. Rubber has elasticity and friction, which increases the friction between the clamping plate 41 and the clamped item, while preventing damage to the clamped item.

[0030] First, a circular block 2 is fixedly connected to the surface of the tube 1. A groove 35 is formed on the surface of the circular block 2, and a recess 36 is formed on the inner wall of the groove 35. A connecting rod 39 is installed on the inner wall of the recess 36, and a spring 310 is fitted onto it. A slider 34 is placed into the recess 36, and the arc surface of the slider 34 slides along the connecting rod 39. One end of the spring 310 is fixed to the surface of the slider 34, and the other end is fixed to the inner wall of the recess 36. A fixing plate 37 is fixedly connected to the surface of the slider 34. A screw 38 is passed through the surface of the fixing plate 37, and one end of the screw 38 is threadedly connected to the surface of the circular block 2. A sliding rod 33 is slidably connected to the surface of the slider 34. One end of the sliding rod 33 is fixedly connected to a fixing block 311, and a long strip plate 32 is rotatably connected to the surface of the fixing block 311. A disc 31 is fixedly connected to the surface of the long strip plate 32. By rotating the screw 38, the position of the slider 34 in the recess 36 can be adjusted. Since the slider 34 is connected to the sliding rod 33, the position of the disc 31 can also be adjusted. When screw 38 is tightened, the position of slider 34 is fixed, and the position of disk 31 is also fixed. When screw 38 is loosened, slider 34 can slide in groove 36 under the action of spring 310 or under the push of external force, thereby driving disk 31 to adjust its position. The sliding groove 35 provides space for partial movement of slider 34, allowing slider 34 to slide in a certain direction on the surface of block 2. The groove 36 limits the range of movement of slider 34 and provides installation space for slider 34, forming an adjustable structure together with slider 34, connecting rod 39, spring 310, and other parts. Slider 34 is a key moving part in adjustment structure 3. Through its connection with screw 38, sliding rod 33, and other parts, its movement in groove 36 can drive other parts to adjust their positions. Fixing plate 37 is fixed to the surface of slider 34, providing a position for screw 38 to pass through and be threaded. Through the threaded connection between screw 38 and block 2, the position of slider 34 can be fixed or adjusted. The screw 38 is configured to fix the position of the slider 34 via a threaded connection. Rotating the screw 38 allows for precise adjustment of the slider 34's position relative to the circular block 2, thereby adjusting the positions of other components connected to the slider 34. The slide bar 33 is configured to slide along the slider 34, with one end connected to the fixed block 311, transmitting the movement of the slider 34 so that its movement drives the movement of the fixed block 311 and its connected components. The fixed block 311 provides a rotatable connection for the elongated plate 32, converting the movement of the slide bar 33 into the rotational movement of the elongated plate 32. The elongated plate 32 is rotatably connected to the fixed block 311 at one end, with a disk 31 fixedly connected to its surface. The position and orientation of the disk 31 can be adjusted by the slider 34 and the slide bar 33. The position and orientation of the disk 31 can be adjusted via the adjustment structure 3, potentially for connecting with other components, blocking, or providing some form of adjustment.The connecting rod 39 guides and limits the slider 34, ensuring its stable sliding within the groove 36 and preventing it from dislodging or shifting during sliding. The spring 310 is fitted onto the arc surface of the connecting rod 39, with one end fixedly connected to the surface of the slider 34 and the other end fixedly connected to the inner wall of the groove 36. When the screw 38 is released, it provides elastic restoring force to the slider 34, allowing it to return to its initial position under a certain external force or automatically adjust its position within a certain range. The adjustment structure 3 facilitates the adjustment of the clamping plate 41, minimizing inconvenience in adjusting pipe joints of different sizes and further improving the ease of operation of the device.

[0031] A square groove 46 is formed on the surface of the slider 34. The movable block 42 is placed in the square groove 46 and can slide within the square groove 46. The movable block 42 is fixedly connected to the arc surface of the slide rod 33. A stop block 43 is fixedly connected to one end of the slide rod 33 to prevent the movable block 42 from slipping off the slide rod 33. A clamping plate 41 is fixedly connected to the surface of the movable block 42. A clamping block 44 and a pad 45 are fixedly connected to the surface of the clamping plate 41. When an item needs to be clamped, the pusher disc 31 rotates the long strip 32, which in turn moves the slide bar 33. The slide bar 33 then moves the clamping plate 41. The moving block 42 slides within the square groove 46, bringing the clamping plate 41 closer to the item to be clamped. The clamping block 44 and the pad 45 then contact the item, clamping it through friction. The square groove 46 provides sliding space for the moving block 42 and restricts its sliding direction, ensuring it can only slide linearly within the groove. The moving block 42, which slides within the square groove 46 and is fixedly connected to the slide bar 33 and clamping plate 41, acts as an intermediate component transmitting the movement of the slide bar 33 to the clamping plate 41. The stop block 43 is fixed to one end of the slide bar 33 to prevent the moving block 42 from slipping off, ensuring the integrity of the clamping structure 4. The clamping plate 41 is fixed to the surface of the movable block 42. As the movable block 42 moves closer to or further away from the object to be clamped, it is the component that directly contacts the clamped object. The clamping block 44, fixed to the surface of the clamping plate 41, has a rectangular cross-section. This may increase the contact area between the clamping plate 41 and the clamped object or provide better adaptability to the clamping shape, thus improving clamping stability. The pad 45, made of rubber, is fixed to the surface of the clamping plate 41. Rubber has a certain elasticity and friction, which increases the friction between the clamping plate 41 and the clamped object while preventing damage to the object. By setting up the clamping structure 4, it is convenient to clamp the pipe connection, minimizing the possibility of instability at the pipe connection and further improving the working stability of the device.
