Description

Technical Field

[0001] The invention relates to the technical field of cranes, and in particular to a crane with an anti-collision mechanism and a bearing structure. Background Art

[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. Cranes are generally used for lifting and installing objects that are inconvenient to move and require a large number of guy ropes to maintain stability. Cranes can be used in relatively narrow conditions and can lift large or small amounts.

[0003] The patent with patent announcement number CN212269213U discloses a small crane with an anti-collision mechanism, which belongs to the technical field of small cranes, including a base plate, a column installed on the top of the base plate, a horizontal plate installed on the top of the column, and horizontal buffer rods are slidably installed at both ends of the base plate and the horizontal plate. One end of the buffer rod is fixedly connected to a vertically arranged vertical plate, and a horizontally arranged horizontal axis is slidably installed on the vertical plate. One end of the horizontal axis passes through the vertical plate and is fixedly connected to the buffer plate. A compression spring is sleeved on the horizontal axis, and the compression spring is located between the vertical plate and the buffer plate. A winch is provided on the horizontal plate, and an inclined rod is installed on the top of the horizontal plate. This patent does not require binding objects with ropes, and electrically clamps and fixes objects, thereby improving the efficiency of lifting. Through elastic support and buffering, the impact of impact force on the crane is reduced, the safety and anti-collision performance of the crane are improved, and the service life of the crane is improved.

[0004] However, this device still has some shortcomings: this device can improve the safety and anti-collision performance of the crane, but when the crane is hoisting heavy materials on the construction site, the crane is prone to top-heavy phenomenon. At this time, the crane is prone to tipping over to one end of the hoisted heavy object, which is likely to increase the hoisting risk and thus increase the construction risk of the workers, and the tipping of the crane is likely to cause huge economic losses. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a crane and a load-bearing structure with an anti-collision mechanism, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a bearing structure, including a rotating shaft assembly, a receiving seat is arranged on the top of the rotating shaft assembly, a driver is arranged on the top of the receiving seat, a winding assembly is arranged on the front of the driver, a support arm is arranged on the left end of the winding assembly, and a hydraulic clamp is fixedly connected to the left end of the support arm through a cable.

[0007] A crane with an anti-collision mechanism comprises the above-mentioned bearing structure and a base, the top of the base is fixedly mounted on the bottom of the receiving seat, and the base is of a hollow design; The base is provided with an anti-dumping device at the periphery, an anti-obstruction device is provided inside the anti-dumping device, and an anti-adhesion device is provided inside the anti-obstruction device; The anti-dumping device includes a plurality of electric push rods, which are equidistant and fixedly installed inside the base, a buffer plate is fixedly installed on the telescopic end of the electric push rod away from the center of the base, the outer wall of the buffer plate is located inside the base, a plurality of resistance blocks are equidistant and fixedly installed on the outer wall of the fixed end of the electric push rod, an L-shaped tough plate is fixedly installed on the side of the buffer plate close to the center of the base, a plurality of L-shaped plates are symmetrically and fixedly installed at the edge of the buffer plate away from the electric push rod, a hollow bottom plate is fixedly installed at the bottom of the L-shaped plate, a plurality of L-shaped plates are fixedly installed on the side close to the center of the hollow bottom plate, a square frame is penetrated and hinged on the outer wall of the cross bar, and a plurality of diagonal rods are equidistant and fixedly installed on the bottom of the square frame.

[0008] According to the above technical solution, the outer wall of the resistance block is located on the movement trajectory of the L-shaped tough plate close to one end of the electric push rod, the outer wall of the hollow bottom plate passes through and is slidably installed inside the base, and a U-shaped groove is opened at the end of the hollow bottom plate away from the base, and a torsion spring is arranged between the inside of the square frame and the cross bar. When it is necessary to hoist the material, the hoisting direction is adjusted by rotating the rotating shaft assembly on the top of the base, and the winding assembly is driven by the driver to lower the cable toward the ground. When the cable is lowered with the inside of the support arm, the cable drives the hydraulic clamp to move synchronously, and the hydraulic clamp clamps the material through hydraulic pressure and then performs the hoisting work; before the crane starts working, the electric push rod is started, and the telescopic end of the electric push rod drives the buffer plate to move away from the center of the base until the buffer plate extends away from the outer wall of the base, and the buffer plate moves away from the center of the base and drives the L-shaped tough plate to move synchronously The L-shaped plate is moved by the user, and the ...

[0009] According to the above technical solution, the anti-obstruction device includes a sliding plate, a vertical rod, a swinging plate and a guide plate. The sliding plate is slidably installed inside the U-shaped groove of the hollow bottom plate near the side of the buffer plate. Both ends of the vertical rod are fixedly installed inside the sliding groove of the sliding plate. The swinging plate passes through and is hinged to the outer wall of the vertical rod. The guide plate is fixedly installed on the outer wall of the swinging plate near the side of the sliding plate.

[0010] According to the above technical solution, a sliding groove is provided at one end of the sliding plate away from the buffer plate, and a torsion spring is arranged between the inside of the swinging plate and the vertical rod. When the hollow bottom plate moves in the direction away from the base, the U-shaped groove inside itself drives the sliding plate to move synchronously, and the sliding plate drives the vertical rod to move synchronously. In the process of the vertical rod driving the swinging plate to move synchronously, the swinging plate contacts the ground or other obstacles at any time to generate a resistance force. At this time, the swinging plate relies on the resistance force to start to generate a rotational force along the outer wall of the vertical rod. When the swinging plate starts to rotate with its own hinge axis as the axis, it will drive the guide plate to move synchronously.

[0011] According to the above technical solution, the anti-obstruction device also includes a plurality of rotating wheels, a reciprocating screw rod, a hollow arc plate and a plurality of scraping blocks, wherein the plurality of rotating wheels are symmetrically and rotatably installed inside the U-shaped groove of the hollow bottom plate, the two ends of the reciprocating screw rod are fixedly installed on the side of the rotating wheel close to the center of the hollow bottom plate, the outer wall of the reciprocating screw rod passes through and is movably installed inside the sliding plate, the outer wall of the hollow arc plate is fixedly installed on the inner wall of the U-shaped groove of the hollow bottom plate, the plurality of scraping blocks are equidistantly and fixedly installed inside the hollow arc plate, the bottom of the scraping block is in contact with the outer wall of the rotating wheel, and the hollow bottom plate drives the rotating wheel to contact the ground during movement. And friction force is generated, and the wheel starts to rotate along the U-shaped groove of the hollow bottom plate through the friction force, and the wheel drives the reciprocating screw to rotate. When the reciprocating screw rotates, the reciprocating spiral groove limits the built-in block of the sliding plate, so that the reciprocating screw can drive the sliding plate to slide back and forth along its own outer wall and reset when it rotates. The sliding plate drives the swing plate and the guide plate to move synchronously, and limits the hollow arc plate through the inner wall of the U-shaped groove of the hollow bottom plate, so that the hollow arc plate is always in a stationary state. At this time, the rotating wheel contacts the scraper block, and the dirt such as mud on the outer wall of the wheel during the rotation is removed by the scraper block.

[0012] According to the above technical solution, the anti-adhesion device includes a U-shaped plate, a transmission belt, a rotating rod and a plurality of dust reduction mesh plates. The bottom of the U-shaped plate is fixedly installed on the top of the hollow bottom plate away from the base. The inner wall of the bottom of the transmission belt is sleeved and transmission-installed on the outer wall of the reciprocating screw rod. Both ends of the rotating rod are fixedly installed inside the U-shaped plate, and a plurality of dust reduction mesh plates are fixedly installed on the outer wall of the rotating rod.

[0013] According to the above technical solution, the outer wall of the rotating rod is driven and installed on the inner wall of the top of the transmission belt, and a plurality of the dust reduction screens are evenly distributed on the outer wall of the rotating rod. When the reciprocating screw rotates, the transmission belt drives the rotating rod to start rotating along the inner wall of the U-shaped plate. When the rotating rod rotates on the inner wall of the U-shaped plate, it drives the dust reduction screen to revolve. When the dust reduction screen revolves, it evenly absorbs the dust that is raised by the sliding plate when it drives away obstacles.

[0014] According to the above technical scheme, the anti-adhesion device also includes a plurality of angular scrapers, spherical blocks, convex rings and telescopic pressure plates. The plurality of angular scrapers are respectively slidably installed on the outer wall of the dust reduction mesh plate through springs. The spherical block is fixedly installed on the outer wall of the angular scraper away from the transmission belt. The convex ring is fixedly installed on the inner wall of the U-shaped plate away from the transmission belt. The arc surface of the convex ring close to the transmission belt is located on the movement trajectory of the spherical block. The bottom of the fixed end of the telescopic pressure plate is fixedly installed on the outer wall of the square frame. The telescopic end of the telescopic pressure plate is located on the movement trajectory of the dust reduction mesh plate. When the dust reduction mesh plate revolves, it drives the angular scrapers to move synchronously. When the angular scrapers revolve, it drives the spherical blocks to move synchronously. The spherical blocks revolve during the process of revolution. The angular scraper slides along the outer wall of the dust reduction screen plate toward the transmission belt through the resistance force. When the spherical block no longer resists the convex block ring arc surface, the angular scraper is reset by the spring force and repeats this process. In addition, the dust reduction screen plate continuously contacts the arc surface of the telescopic end of the telescopic pressure plate during its revolution. Downward pressure is generated on the telescopic end of the telescopic pressure plate through the revolution of the dust reduction screen plate, and the telescopic end of the telescopic pressure plate shrinks toward its own fixed end through the resistance of the dust reduction screen plate. When the dust reduction screen plate no longer presses the telescopic end of the telescopic pressure plate, the telescopic pressure plate resets its own telescopic end through the built-in spring, and causes the square frame to generate a downward movement force through the transmission of force, and the square frame causes the diagonal rod to be subjected to force synchronously.

[0015] The present invention provides a crane and a load-bearing structure with an anti-collision mechanism, which have the following beneficial effects: (1) The present invention adopts the setting of the anti-dumping device, and cooperates with the electric push rod, the buffer plate, the resistance block, the L-shaped tough plate, the L-shaped plate, the hollow bottom plate, the cross bar, the square frame and the diagonal rod to make the buffer plate rely on slight vibration to make itself move more smoothly in the process of moving away from the base, thereby preventing the buffer plate from getting stuck with the inside of the base during long-term use, thereby increasing wear. At the same time, the buffer plate provides anti-collision protection for the outer deformation of the base, thereby preventing external moving objects from directly hitting the base during movement, thereby reducing the lifting stability; at the same time, relying on the extension of the hollow bottom plate, the contact area between the base and the ground is effectively expanded, thereby improving the overall stability of the equipment, and preventing the support arm from tipping over due to insufficient bottom counterweight when lifting heavier materials. Since the diagonal rod extends into the ground at an oblique angle, the force area between the diagonal rod and the ground is effectively increased, thereby preventing one end of the crane from tipping over due to uneven force, thereby effectively avoiding the lifting risk and equipment damage risk.

[0016] (2) The present invention sets an anti-obstruction device, and cooperates with a hollow bottom plate, a sliding plate, a vertical rod, a swinging plate, a guide plate, a rotating wheel, a reciprocating screw rod, a hollow arc plate and a scraping block. The swinging plate swings away obstacles such as gravel that it contacts, and the guide plate contacts and guides the gravel and other obstacles through its own arc surface during the synchronous movement of the swinging plate, so that the obstacles can quickly move away from the movement path of the hollow bottom plate, thereby preventing the hollow bottom plate from reducing the fit with the ground, and preventing the inclined rod from being difficult to extend into the ground due to the obstruction of the obstacle, thereby preventing the overall stability of the equipment from being reduced; and effectively expanding the range of movement of the sliding plate and the swinging plate, that is, effectively improving the effect of removing obstacles on the movement path of the hollow bottom plate, ensuring the flatness of the road surface, and enabling the bottom of the hollow bottom plate to be relatively completely fitted with the ground, while preventing the outer wall of the rotating wheel from carrying wet mud to increase the overall bumpiness of the equipment during movement, and preventing the mud from aggravating the oxidation rate of the rotating wheel and thus shortening its service life.

[0017] (3) The present invention adopts the setting of the anti-adhesion device, and cooperates with the reciprocating screw, U-shaped plate, transmission belt, rotating rod, dust suppression mesh plate, angle scraper, spherical block, convex ring and telescopic pressure plate to intercept the dust and other dirt raised by the dust suppression mesh plate, so as to prevent the dirt from eroding and adhering to the sliding gap between the buffer plate and the base, and avoid the filling of the movable gap between the two, thereby increasing the difficulty of extension and resetting, and avoid the reduction of the extension area of ​​the base in a single direction, thereby affecting the stability of the equipment as a whole when it is hit; at the same time, the reciprocating scraping of the angle scraper plate causes the dirt intercepted on the surface of the dust suppression mesh plate to be evenly distributed, and avoids excessive accumulation of dirt on a part of the dust suppression mesh plate and the dirt falling off during the revolution, thereby extending the maintenance cycle and further reducing the possibility of dirt filling the sliding gap. At the same time, the knocking of the dust suppression mesh plate causes the inclined rod to extend into the ground more quickly, and prevents the ground from being too hard to reduce the penetration depth of the inclined rod, so as to ensure that the inclined rod can be firmly inserted into the ground at an oblique angle.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 9 One embodiment of the present invention is: a bearing structure, including a shaft assembly 1, a receiving seat 2 is arranged on the top of the shaft assembly 1, a driver 21 is arranged on the top of the receiving seat 2, a winding assembly 22 is arranged on the front of the driver 21, a support arm 23 is arranged on the left end of the winding assembly 22, and a hydraulic clamp 24 is fixedly connected to the left end of the support arm 23 through a cable.

[0022] A crane with an anti-collision mechanism comprises the above-mentioned bearing structure and a base 3, the top of the base 3 is fixedly mounted on the bottom of the receiving seat 2, and the base 3 is a hollow design; An anti-dumping device 4 is arranged on the periphery of the base 3, an anti-obstruction device 5 is arranged inside the anti-dumping device 4, and an anti-adhesion device 6 is arranged inside the anti-obstruction device 5; The anti-dumping device 4 includes a plurality of electric push rods 41, which are equidistant and fixedly installed inside the base 3. A buffer plate 42 is fixedly installed on the telescopic end of the electric push rod 41 away from the center of the base 3, and the outer wall of the buffer plate 42 is located inside the base 3. A plurality of abutment blocks 43 are equidistant and fixedly installed on the outer wall of the fixed end of the electric push rod 41. An L-shaped tough plate 44 is fixedly installed on the side of the buffer plate 42 close to the center of the base 3. A plurality of L-shaped plates 45 are symmetrically and fixedly installed at the edge of the side of the buffer plate 42 away from the electric push rod 41. A hollow bottom plate 46 is fixedly installed at the bottom of the L-shaped plate 45. A plurality of L-shaped plates 45 are fixedly installed on the side close to the center of the hollow bottom plate 46. A square frame 48 is penetrated and hinged on the outer wall of the cross bar 47, and a plurality of diagonal rods 49 are equidistant and fixedly installed on the bottom of the square frame 48.

[0023] The outer wall of the abutment block 43 is located on the motion track of one end of the L-shaped tough plate 44 close to the electric push rod 41. The outer wall of the hollow bottom plate 46 penetrates and is slidably installed inside the base 3. A U-shaped groove is provided at the end of the hollow bottom plate 46 away from the base 3. A torsion spring is provided between the inside of the square frame 48 and the cross bar 47. Through the above cooperation, the buffer plate 42 relies on slight vibration to make itself move more smoothly in the direction away from the base 3, thereby preventing the buffer plate 42 from being blocked with the inside of the base 3 during long-term use, thereby increasing wear. At the same time, the buffer plate 42 has a good impact on the outer shape of the base 3. Anti-collision protection is provided to prevent external moving objects from directly colliding with the base 3 during movement, thereby reducing the hoisting stability; through the above cooperation, the extension of the hollow bottom plate 46 is relied on to effectively expand the contact area between the base 3 and the ground, thereby improving the overall stability of the equipment, and preventing the support arm 23 from tipping over due to insufficient bottom counterweight when hoisting heavier materials. Since the inclined rod 49 extends into the ground at an oblique angle, the force-bearing area between the inclined rod 49 and the ground is effectively increased, preventing one end of the crane from tipping over due to uneven force, and effectively avoiding the risk of hoisting and equipment damage.

[0024] When in use, when it is necessary to hoist the material, the hoisting direction is adjusted by rotating the shaft assembly 1 on the top of the base 3, and the winding assembly 22 is driven by the driver 21 to lower the cable toward the ground. When the cable is lowered with the inside of the support arm 23, the cable drives the hydraulic clamp 24 to move synchronously. The hydraulic clamp 24 clamps the material through the hydraulic pressure and then performs the hoisting work; before the crane starts working, the electric push rod 41 is started, and the telescopic end of the electric push rod 41 drives the buffer plate 42 to move away from the center of the base 3 until the buffer plate 42 extends away from the outer wall of the base 3. When the buffer plate 42 moves away from the center of the base 3, it drives the L-shaped The tough plates 44 move synchronously, and the L-shaped tough plates 44 will contact the resistance block 43 during the movement to generate a resistance force. The fixed end of the electric push rod 41 limits the resistance block 43. At this time, the L-shaped tough plate 44 bends and deforms during the resistance. The L-shaped tough plate 44 and the resistance block 43 are guided by the arc surfaces between each other, so that the L-shaped tough plate 44 in a bent posture can pass over the resistance block 43. At this time, the L-shaped tough plate 44 will swing back and forth during the process of resetting by its own toughness, thereby generating vibration, and the buffer plate 42 is prompted to generate slight vibration through the transmission of force. Through the above cooperation, the buffer plate 42 relies on slight vibration to prompt itself The movement in the direction away from the base 3 is smoother, preventing the buffer plate 42 from getting stuck with the inside of the base 3 during long-term use, thereby increasing wear. At the same time, the buffer plate 42 provides anti-collision protection for the outer deformation of the base 3, preventing external moving objects from directly hitting the base 3 during movement, thereby reducing the stability of the lifting. When the buffer plate 42 moves in the direction away from the base 3, it drives the L-shaped plate 45 to move synchronously, and the L-shaped plate 45 pulls the hollow bottom plate 46 to extend synchronously from the inside of the base 3. At the same time, the L-shaped plate 45 drives the cross bar 47 to move synchronously, and the cross bar 47 drives the square frame 48 to move synchronously, and the square frame 48 drives the diagonal rod 49 to move with the ground The surfaces are in contact at an inclined angle, so when the square frame 48 moves synchronously with the L-shaped plate 45, the square frame 48 will drive the inclined rod 49 to gradually insert into the ground at an inclined angle. Through the above cooperation and relying on the extension of the hollow bottom plate 46, the contact area between the base 3 and the ground is effectively expanded, thereby improving the overall stability of the equipment and preventing the support arm 23 from tipping over due to insufficient bottom counterweight when hoisting heavier materials. Since the inclined rod 49 extends into the ground at an inclined angle, the force area between the inclined rod 49 and the ground is effectively increased, preventing one end of the crane from tipping over due to uneven force, and effectively avoiding the risk of hoisting and equipment damage.

[0025] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-obstruction device 5; The anti-obstruction device 5 includes a sliding plate 51, a vertical rod 52, a swinging plate 53 and a guide plate 54. The sliding plate 51 is slidably installed inside the U-shaped groove of the hollow bottom plate 46 near the side of the buffer plate 42. Both ends of the vertical rod 52 are fixedly installed inside the sliding groove of the sliding plate 51. The swinging plate 53 passes through and is hinged at the outer wall of the vertical rod 52. The guide plate 54 is fixedly installed on the outer wall of the swinging plate 53 near the side of the sliding plate 51.

[0026] A sliding groove is provided at one end of the sliding plate 51 away from the buffer plate 42, and a torsion spring is arranged between the inside of the swing plate 53 and the vertical rod 52. Through the above cooperation, the swing plate 53 is relied on to swing away obstacles such as gravel that it contacts, and the guide plate 54 moves synchronously with the swing plate 53. The guide plate 54 contacts and guides obstacles such as gravel through its own arc surface, so that the obstacles can quickly move away from the movement path of the hollow bottom plate 46, preventing the hollow bottom plate 46 from reducing its fit with the ground, and at the same time preventing the inclined rod 49 from being difficult to penetrate into the ground due to the obstruction of obstacles, thereby preventing the overall stability of the equipment from being reduced.

[0027] The anti-obstruction device 5 also includes a plurality of rotating wheels 55, a reciprocating screw rod 56, a hollow arc plate 57 and a plurality of scraping blocks 58. The plurality of rotating wheels 55 are symmetrically and rotatably mounted inside the U-shaped groove of the hollow bottom plate 46. Both ends of the reciprocating screw rod 56 are fixedly mounted on the rotating wheel 55 near the center of the hollow bottom plate 46. The outer wall of the reciprocating screw rod 56 penetrates and is movably mounted inside the sliding plate 51. The outer wall of the hollow arc plate 57 is fixedly mounted on the inner wall of the U-shaped groove of the hollow bottom plate 46. The plurality of scraping blocks 58 are equidistantly and fixedly mounted on the hollow arc plate 51. Inside the plate 57, the bottom of the scraper block 58 contacts the outer wall of the wheel 55. The above cooperation effectively expands the range of movement of the sliding plate 51 and the swing plate 53, that is, effectively improves the effect of removing obstacles on the movement path of the hollow bottom plate 46, ensures the flatness of the road surface, and enables the bottom of the hollow bottom plate 46 to be relatively completely in contact with the ground. At the same time, it prevents the outer wall of the wheel 55 from carrying wet soil to increase the overall bumpiness of the equipment during movement, and prevents the soil from aggravating the oxidation rate of the wheel 55 and thus shortening its service life.

[0028] When in use, when the hollow bottom plate 46 moves away from the base 3, the U-shaped groove inside it drives the sliding plate 51 to move synchronously, the sliding plate 51 drives the vertical rod 52 to move synchronously, and the vertical rod 52 drives the swing plate 53 to move synchronously. In the process, the swing plate 53 contacts the ground or other obstacles at any time to generate resistance. At this time, the swing plate 53 starts to generate a rotation force along the outer wall of the vertical rod 52 by relying on the resistance force. When the swing plate 53 starts to rotate with its own hinge axis as the axis, it will drive the guide plate 54 to move synchronously. The guide plate 54 moves synchronously with the swing plate 53, and the guide plate 54 contacts and guides the obstacles such as gravel through its own arc surface, so that the obstacles can quickly move away from the movement path of the hollow bottom plate 46, preventing the hollow bottom plate 46 from reducing the fit between the ground and the inclined rod 49 from being blocked by obstacles, thereby preventing the overall stability of the equipment from being reduced. During the movement of the hollow bottom plate 46, the rotating wheel 55 is driven to contact the ground and generate friction. The rotating wheel 55 is moved by The friction force starts to rotate along the U-shaped groove inside the hollow bottom plate 46, and the rotating wheel 55 drives the reciprocating screw rod 56 to rotate. When the reciprocating screw rod 56 rotates, the reciprocating spiral groove limits the built-in block of the sliding plate 51, so that the reciprocating screw rod 56 can drive the sliding plate 51 to slide back and forth along its own outer wall and reset. The sliding plate 51 drives the swing plate 53 and the guide plate 54 to move synchronously, and limits the hollow arc plate 57 through the inner wall of the U-shaped groove of the hollow bottom plate 46, so that the hollow arc plate 57 is always in a stationary state. At this time, the rotating wheel 55 and The scraper block 58 contacts the outer wall of the wheel 55, and the dirt such as the mud on the outer wall of the wheel 55 during the rotation is removed by the scraper block 58. The above cooperation effectively expands the range of movement of the sliding plate 51 and the swing plate 53, that is, effectively improves the effect of removing obstacles on the movement path of the hollow bottom plate 46, ensures the flatness of the road surface, and enables the bottom of the hollow bottom plate 46 to be relatively completely in contact with the ground. At the same time, it prevents the outer wall of the wheel 55 from carrying wet mud to increase the overall bumpiness of the equipment during movement, and prevents the mud from aggravating the oxidation rate of the wheel 55 and thus shortening its service life.

The bottom of the U-shaped plate 61 is fixedly installed on the top of the hollow bottom plate 46 away from the base 3. The inner wall of the bottom of the transmission belt 62 is sleeved and transmission-installed on the outer wall of the reciprocating screw rod 56. Both ends of the rotating rod 63 are fixedly installed inside the U-shaped plate 61, and a plurality of dust reduction mesh plates 64 are fixedly installed on the outer wall of the rotating rod 63.

[0030] The outer wall of the rotating rod 63 is installed on the inner wall of the top of the transmission belt 62, and a number of dust suppression mesh plates 64 are evenly distributed on the outer wall of the rotating rod 63. Through the above cooperation, the dust suppression mesh plates 64 are used to intercept the raised dust and other dirt to prevent the dirt from eroding and adhering to the sliding gap between the buffer plate 42 and the base 3, to prevent the active gap between the two from being filled, thereby increasing the difficulty of extension and resetting, and to prevent the extension area of ​​the base 3 in a single direction from being reduced, thereby affecting the stability of the entire equipment when it is hit.

[0031] The anti-adhesion device 6 also includes a plurality of angular scrapers 65, a spherical block 66, a convex ring 67 and a telescopic pressure plate 68. The plurality of angular scrapers 65 are respectively slidably mounted on the outer wall of the dust suppression screen 64 through springs. The spherical block 66 is fixedly mounted on the outer wall of the angular scraper 65 on the side away from the transmission belt 62. The convex ring 67 is fixedly mounted on the inner wall of the U-shaped plate 61 on the side away from the transmission belt 62. The arc surface of the convex ring 67 on the side close to the transmission belt 62 is located on the movement trajectory of the spherical block 66. The bottom of the fixed end of the telescopic pressure plate 68 is fixedly mounted on the outer wall of the square frame 48. The telescopic pressure plate 68 The telescopic end is located on the movement trajectory of the dust reduction mesh plate 64. Through the above cooperation, the reciprocating scraping of the angle scraper 65 can make the dirt intercepted on the surface of the dust reduction mesh plate 64 be evenly distributed, avoiding excessive accumulation of dirt in a part of the dust reduction mesh plate 64 and causing it to fall off during the revolution, thereby extending the maintenance cycle and further reducing the possibility of dirt filling the sliding gap. At the same time, with the help of the knocking of the dust reduction mesh plate 64, the inclined rod 49 can penetrate into the ground more quickly, preventing the ground from being too hard to reduce the penetration depth of the inclined rod 49, and ensuring that the inclined rod 49 can be firmly inserted into the ground at an oblique angle.

[0032] When in use, the reciprocating screw rod 56 rotates and drives the rotating rod 63 to rotate along the inner wall of the U-shaped plate 61 through the transmission belt 62. The rotating rod 63 drives the dust suppression mesh plate 64 to revolve when the inner wall of the U-shaped plate 61 rotates. When the dust suppression mesh plate 64 revolves, the dust that is raised by the sliding plate 51 due to the obstacle is uniformly adsorbed. Through the above cooperation, the dust suppression mesh plate 64 intercepts the raised dust and other dirt, prevents the dirt from eroding and adhering to the sliding gap between the buffer plate 42 and the base 3, and avoids the active gap between the two from being filled, thereby increasing the The extension and reset difficulty is increased to avoid the reduction of the extension area of ​​the base 3 in a single direction, thereby affecting the stability of the entire device when it is hit; when the dust suppression screen 64 revolves, it drives the angular scraper 65 to move synchronously, and when the angular scraper 65 revolves, it drives the spherical block 66 to move synchronously. During the revolution of the spherical block 66, it contacts the outer wall arc surface of the protrusion ring 67 and generates a resistance force. The angular scraper 65 slides along the outer wall of the dust suppression screen 64 toward the transmission belt 62 through the resistance force. When the spherical block 66 no longer resists the arc surface of the protrusion ring 67, the angular scraper 65 The retractable end of the telescopic pressure plate 68 is retracted toward the inside of its own fixed end through the resistance of the dust reduction mesh plate 64. When the dust reduction mesh plate 64 no longer suppresses the retractable end of the telescopic pressure plate 68, the telescopic pressure plate 68 resets its own retractable end through the built-in spring, and the square frame 48 generates a downward movement force through the transmission of force, which promotes the square frame 48 to The inclined rod 49 is subjected to force synchronously, and the reciprocating scraping of the angle scraper 65 is used to evenly distribute the dirt trapped on the surface of the dust suppression mesh plate 64, thereby avoiding excessive accumulation of dirt on a part of the dust suppression mesh plate 64 and causing it to fall off during the revolution. This extends the maintenance cycle and further reduces the possibility of dirt filling the sliding gap. At the same time, the knocking of the dust suppression mesh plate 64 is used to enable the inclined rod 49 to penetrate the ground more quickly, preventing the ground from being too hard and reducing the penetration depth of the inclined rod 49, thereby ensuring that the inclined rod 49 can be firmly inserted into the ground at an oblique angle.
