Description

Technical Field

[0001] The present application relates to the technical field of cleaning devices, and in particular to a cleaning device for cement solidified in a cement silo. Background Art

[0002] Cement silo, also known as mud silo or cement tank, is a device specially used to store cement. It is usually used for bulk cement storage in concrete mixing plants to ensure a stable supply of cement to the mixing plant. During storage, the cement silo may not be well sealed, resulting in humid air. Cement exposed to a humid environment for a long time will absorb moisture from the air, causing hydration reactions between cement particles, resulting in cement coagulation and agglomeration. During storage, the cement coagulated on the inner wall of the cement silo needs to be cleaned to ensure that the cement silo can supply cement to the mixing plant normally.

[0003] Referring to the Chinese patent with announcement number CN204320758U and name "A new type of high-efficiency cement silo cleaning equipment", the high-efficiency cement silo cleaning equipment includes a turntable and a cleaning component, the cleaning component includes a frame, an extension arm, a hammer head, a wire rope and a locking block, and the cleaning component is suspended under the turntable by a rope. When cleaning the lumps on the inner wall of the cement silo, the turntable drives the frame to rotate while rotating, and the extension arms of the frame are horizontally distributed and symmetrically arranged at both ends of the frame drive the hammer head to retract inward or extend outward at the same time, and the hammer head is driven by the motor to rotate, and the wire rope installed on the hammer head contacts the lumps on the inner side of the cement silo to break them up, and the locking block connected to the wire rope can increase the crushing force and strength of the lumps, and can effectively clean the solidified cement on the inner wall of the cement silo.

[0004] When the above-mentioned cleaning equipment is in use, since the cleaning component is suspended under the turntable, it is easy to swing when rotating. Furthermore, when the hammer head rotates under the drive of the motor, the wire rope installed on the hammer head will gradually rise and straighten under the inertia of the rotation force, and the end of the wire rope and the locking block can contact and crush the lumps on the inner side of the cement silo. However, when the wire rope and the locking block contact the lumps, the lumps have relative resistance to the wire rope. After the wire rope collides with the lumps, the wire rope is prone to irregular swinging trajectories, and the amplitude of the swing is easy to lose control. Therefore, when the cleaning component swings irregularly, it is difficult for the wire rope and the locking block to control the contact point with the inner wall of the cement silo, which may cause the wire rope and the locking block to knock the inner wall of the cement silo, and the inner wall of the cement silo is prone to scratches and pits. Summary of the invention

[0005] In view of this, the present application provides a cleaning device for solidified cement in a cement silo, which is mainly used to solve the problem that the cleaning piece swings too much, causing scratches and pits on the inner wall of the cement silo.

[0006] In order to solve the above technical problems, the present application provides a cleaning device for cement condensation in cement silos, comprising a first steel wire rope, a second steel wire rope and a cleaning assembly for cleaning the condensation cement. It also comprises a balance bar, a counterweight and a balance pressing cylinder, wherein the center of the balance bar is hingedly arranged at the traction end of the first steel wire rope through a hinge shaft, and the weights of the ends of the balance bar on both sides of the hinge shaft are unequal so that the balance bar can tilt in a natural state; the traction end of the second steel wire rope is installed with a balance pressing cylinder, and the balance pressing cylinder comprises a cylinder body with a perforation arranged in the center, the traction end of the first steel wire rope is hingedly arranged with the balance bar after passing through the perforation, and the traction end of the second steel wire rope is fixedly connected with the cylinder body so that the balance bar tilts when the balance pressing cylinder is pulled upward; a connecting piece is arranged at the upper end of the cleaning assembly, and the connecting piece is cylindrical, and a perforated through hole is penetrated through the center axis of the connecting piece, and the first steel wire rope and the second steel wire rope pass through the through hole.

[0007] Beneficial effect: the counterweight block can drive the balance bar hinged at the end of the first steel wire rope to tilt toward one side of the counterweight block, and under the extension of the first steel wire rope, the balance bar is moved out from the discharge port inside the cement silo, and the balance pressing cylinder is driven by the second steel wire rope to contact the center of the balance bar, so that the balance bar is horizontal and clamped on the outside of the discharge port of the cement silo. At this time, the first steel wire rope is in a taut state. When the cleaning assembly rotates to clean the solidified cement on the inner wall of the cement silo, the taut first steel wire rope can limit the swing amplitude of the cleaning assembly to prevent the cleaning assembly from swinging too much, and can reduce the collision and scratches of the end of the cleaning assembly on the inner wall of the cement silo.

[0008] Optionally, the top of the cleaning component is hoisted by a connected third steel wire rope, and the third steel wire rope is provided in four pieces and is used to drive the cleaning component to move vertically up and down.

[0009] Beneficial effect: The arrangement of the four third steel wire ropes can enhance the stability of movement in the process of driving the cleaning component to move vertically up and down.

[0010] Optionally, the cleaning assembly includes a hydraulic rod, an articulated base, an auxiliary rod, a receiving plate and a breaker. Four hydraulic rods are arranged in a circular array on the connecting piece, and an articulated base is sleeved on the piston rod of the hydraulic rod; an auxiliary rod is hingedly arranged on the articulated base, and a receiving plate is hingedly arranged on the upper part of the cylinder side wall of the hydraulic rod, and the end of the auxiliary rod away from the articulated base is hinged to the portion of the receiving plate near the middle, and a breaker is arranged on the end of the receiving plate away from the hydraulic rod; a clamping assembly is arranged on the articulated base and the piston rod to limit the sliding of the articulated base on the piston rod.

[0011] Beneficial effect: When the articulated base is connected to the piston rod of the hydraulic rod through the clamping assembly, the piston rod on the hydraulic rod can drive one end of the auxiliary rod to slide up and down by telescoping, and the receiving plate hinged to the other end of the auxiliary rod can open and close a certain angle around the side wall of the hydraulic rod cylinder, so that the breaker hammer contacts the solidified cement on the inner wall of the cement silo and knocks it down.

[0012] Optionally, the clamping assembly includes a spring and a ball. A semicircular groove is provided on the piston rod, and the hinged base includes a base body, a circular hole is provided through the center of the base body, a rectangular groove is provided on the inner side wall of the circular hole, a spring is provided in the rectangular groove, and a round ball matching the semicircular groove is connected to one end of the spring away from the bottom of the rectangular groove.

[0013] Beneficial effect: When the half part of the ball facing the semicircular groove contacts the semicircular groove, the ball can be clamped in the semicircular groove to limit the hinged base.

[0014] When the falling cement hits the receiving plate and the impact force of the cement is large enough, the ball will break away from the semicircular groove and the receiving plate will slide down by itself, which can prevent the cement from damaging the receiving plate and the drive motor.

[0015] Four hydraulic rods and four corresponding receiving plates are arranged at the same time, so as to prevent that when one or two receiving plates are closed, the other receiving plates which are not closed will drive the breaker to continue to clean the solidified cement on the inner wall of the cement silo, thereby ensuring work efficiency.

[0016] Optionally, the connecting member includes an inner sleeve and an outer sleeve. A circular clamping block is fixedly arranged on the outer side wall of the inner sleeve, a circular clamping groove matching the circular clamping block is opened on the inner side of the outer sleeve, and the inner sleeve is clamped on the outer sleeve.

[0017] Beneficial effect: Through the circular clamping block and the circular clamping groove, the inner sleeve can be clamped on the inner side of the outer sleeve and rotated.

[0018] Optionally, a driving assembly for driving the inner sleeve to rotate is installed on the outer sleeve.

[0019] Beneficial effect: the driving assembly drives the inner sleeve to rotate inside the outer sleeve.

[0020] Optionally, the driving assembly includes a driving motor, a gear and a gear ring. The driving motor is symmetrically mounted on the inner top of the outer sleeve, the output shaft of the driving motor is mounted with a gear, and the inner wall of the inner sleeve is fixedly mounted with a gear ring meshing with the gear.

[0021] Beneficial effect: the output source of the driving motor drives the gear to rotate, and then the gear ring meshing with the gear rotates, the inner sleeve rotates inside the outer sleeve, the hydraulic rod is set at the bottom of the inner sleeve of the connecting part, and the inner sleeve drives the hydraulic rod to rotate.

[0022] Optionally, a plurality of crushing plates are arranged in a circular array on the balanced pressing cylinder.

[0023] Beneficial effect: The second steel wire rope is driven by the winding machine to reciprocate the crushing plate up and down, and hits the coagulated cement at the discharge port, thereby further crushing the coagulated cement accumulated at the discharge port and causing it to flow out from the discharge port.

[0024] Optionally, a pulley is provided on the inner wall of the cylinder of the balanced pressing cylinder, and the pulleys are distributed in a ring array around the first steel wire rope.

[0025] Beneficial effect: when the second steel wire rope drives the balancing pressing cylinder to move up and down, the pulley arranged through the center of the balancing pressing cylinder can assist the balancing pressing cylinder to slide up and down more easily.

[0026] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By clamping the balance bar on the outside of the discharge port of the cement silo, the first steel wire rope hinged on the balance bar is penetrated and set on the center of the cleaning component. When the cleaning component rotates and the breaker collides with the coagulated cement on the inner wall of the cement silo, the first steel wire rope can limit the cleaning component, reduce the shaking amplitude of the cleaning component and the breaker, reduce the collision probability between the breaker and the inner wall of the cement silo, and protect the inner wall of the cement silo.

[0028] 2. When cement falls on the board and the impact force is large enough, the receiving plate is under pressure, causing the ball to leave the semicircular groove and retract into the rectangular groove under the elastic force of the spring. The receiving plate shrinks by itself, which can prevent the receiving plate from being damaged by the solidified cement.

[0029] 3. The receiving plate is set as a long plate from top to bottom. The shape of the long plate is set downward from right to left. The receiving plate receives the solidified cement falling from above. The inclined surface of the receiving plate from top to bottom always keeps rotating clockwise. When the cement falls and hits the receiving plate, the clockwise rotation of the receiving plate can be further promoted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 9 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 This embodiment provides a cleaning device for solidified cement in a cement silo, which is arranged on a cement silo 1, includes a first steel wire rope 2, a second steel wire rope 3 and four third steel wire ropes 4, and also includes a limiting component, a cleaning component 5, a clamping component, a connecting piece 51, a driving component 6, a crushing plate 7 and a pulley 24.

[0042] The first steel wire rope 2 and the second steel wire rope 3 clamp the limit assembly on the outside of the discharge port of the cement silo 1 to reduce the swing amplitude of the cleaning assembly 5 during the rotation process. The cleaning assembly 5 connected to the third steel wire rope 4 is driven by the driving assembly 6 to rotate to clean the solidified cement on the inner wall of the cement silo 1.

[0043] Among them, the retraction and release actions of the first steel wire rope 2, the second steel wire rope 3 and the four third steel wire ropes 4 are all completed by an external winding machine, and the first steel wire rope 2, the second steel wire rope 3 and the third steel wire rope 4 can be independently retracted and released by three independent winding machines.

[0044] Reference Figure 3 and Figure 4 The limit assembly includes a hinge shaft, a balance bar 21, a counterweight 22 and a balance pressing cylinder 23. The hinge shaft is installed at the traction end of the first steel wire rope 2, the balance bar 21 is set to be trapezoidal, and the center of the balance bar 21 is hingedly set at the traction end of the first steel wire rope 2 through the hinge shaft. The length of the balance bar 21 is set to be slightly larger than the diameter of the discharge port at the bottom of the general cement silo 1, so that when the balance bar 21 is set horizontally, it can be clamped on the outside of the discharge port of the cement silo 1, so that the first steel wire rope 2 can be tightened when the first steel wire rope 2 is pulled, thereby limiting the swing amplitude of the first steel wire rope 2 and the cleaning assembly 5. The balance bar 21 is provided with a receiving groove with an opening facing downward, and the counterweight 22 is arranged in the receiving groove at one end of the balance bar 21, so that the weight of one end of the balance bar 21 is greater than that of the other end, so that when the balance bar 21 is hung at the lower section of the second steel wire rope 3 and is in a natural state, the balance bar 21 can be tilted and close to a vertical state.

[0045] The balance pressing cylinder 23 includes a cylindrical body, and a through hole extending along the axis of the body is provided inside the body, and the through hole constitutes a through hole for passing the second steel wire rope 3. The body is made of metal material, and the wall of the body has a certain thickness, so that the lower end surface of the body constitutes a pressing surface that can press the upper surface of the balance bar, and the weight of the body is sufficient to restore the balance bar 21 to a horizontal state when the lower end surface of the body is pressed on the upper surface of the balance bar 21. The through hole in the body is a circular hole, and the diameter of the hole is slightly larger than the diameter of the second steel wire rope 3, so as to prevent the axis of the body from deviating from the axis of the second steel wire rope 3 after the body is pressed on the balance bar 21.

[0046] When in use, first pull the second steel wire rope 3 to separate the balance pressing cylinder 23 from the balance bar 21. Under the action of gravity, the balance bar 21 tilts, and the first steel wire rope 2 drives the balance bar 21 to move vertically downward to the outside of the discharge port. Then, driven by the second steel wire rope 3, the balance pressing cylinder 23 moves downward to press the center of the balance bar 21 to keep the balance bar 21 horizontal, and at the same time, the first steel wire rope 2 and the second steel wire rope 3 are wound upward, driving the inclined surfaces at both ends of the trapezoidal balance bar 21 to contact the bottom edge of the discharge port of the cement silo 1. The first steel wire rope 2 running through the center of the cleaning component 5 can limit the swing amplitude of the cleaning component 5 during rotation.

[0047] Reference Figure 1 and Figure 3 The cleaning assembly 5 includes a hydraulic rod 52, a hinged base 53, an auxiliary rod 54, a receiving plate 55 and a breaker hammer 56.

[0048] Reference Fig. 9 The connecting member 51 includes an inner sleeve 511, an outer sleeve 512, a circular clamping block and a circular clamping groove. The top of the inner sleeve 511 and the bottom of the outer sleeve 512 are both through-set, the outer sleeve 512 is located above the inner sleeve 511 and the inner sleeve 511 is sleeved inside the outer sleeve 512, and under the clamping connection of the circular clamping block and the circular clamping groove, the inner sleeve 511 rotates around the central axis of the outer sleeve 512 inside the outer sleeve 512; the inner sleeve 511 can be sleeved on the outer sleeve 512 by the principle of thermal expansion and contraction;

[0049] A sealed bearing is provided at the connection between the inner sleeve 511 and the outer sleeve 512. The cleaning assembly 5 fixedly connected to the bottom of the inner sleeve 511 is pressed downward on the outer sleeve 512. The provision of the sealed bearing enables the inner sleeve 511 to rotate better on the outer sleeve 512.

[0050] The third steel wire rope 4 is connected to the top of the connecting piece 51 , and the lower ends of the four third steel wire ropes 4 are fixedly connected to the top surface of the outer sleeve 512 , and are evenly distributed in the circumferential direction around the axis of the outer sleeve 512 .

[0051] The receiving plate 55 is arranged in a long plate shape from top to bottom, and the shape of the long plate is arranged downwardly tilted from right to left; the top of the cylinder body of the hydraulic rod 52 is arranged in a circular array and fixedly installed at the bottom of the connecting piece 51, and the hydraulic rod 52 extends vertically downward; the hydraulic rod 52 is hinged to the auxiliary rod 54 through the hinge base 53, one end of the auxiliary rod 54 is hinged to the hinge base 53, and the other end is hinged to the upper center of the inner side of the receiving plate 55. There are four hydraulic rods 52, which can prevent the other unclosed receiving plates 55 and the breaker hammer 56 at the end of the receiving plate 55 from continuing to work when one or two of the receiving plates 55 are closed; the receiving plate 55 is driven to open and close a certain angle by the extension and retraction of the hydraulic rod 52, so that the breaker hammer 56 can contact with the coagulated cement of different thicknesses to crush it.

[0052] Start the hydraulic rod 52, which drives the hinged base 53 to move vertically up and down during the extension and retraction process. Under the connection of the auxiliary rod 54, the receiving plate 55 rotates with its own hinge axis of the cylinder side wall on the hydraulic rod 52 as the reference, so that the receiving plate 55 opens and closes to different degrees, so that the breaker 56 contacts the solidified cement on the inner side of the cement silo 1 to break the solidified cement.

[0053] Reference Figure 4 , Figure 7 and Figure 8 The clamping assembly includes a spring 532 and a ball 533 . The spring 532 is arranged horizontally in the rectangular groove 531, one end of the spring 532 is fixedly connected to the side wall of the ball 533, and the other end of the spring 532 is fixedly connected to the inner wall of the rectangular groove 531. The ball 533 is retracted into the rectangular groove 531 or half of the ball 533 is clamped in the semicircular groove 521 under the elastic force of the spring 532; the semicircular groove 521 is arranged in an annular array on the piston rod of the hydraulic rod 52, and is set to four. The rectangular groove 531 corresponds to the semicircular groove 521 annular array and is opened on the inner wall of the hinged base 53. Correspondingly, the spring 532 and the ball 533 are arranged in four in each semicircular groove 521 and rectangular groove 531, which can enhance the stability of the opening and closing of the receiving plate 55 during the opening and closing process of the receiving plate 55; the ball 533 is clamped in the semicircular groove 521 or the rectangular groove 531, which can make the receiving plate 55 slide down by itself or control the opening and closing of the receiving plate 55.

[0054] When the clamping assembly is clamped to the hinged base 53, the semicircular groove 521 corresponds to the rectangular groove 531 and under the elastic force of the spring 532, half of the ball 533 is clamped inside the semicircular groove 521 to complete the clamping of the hinged base 53, and then the hydraulic rod 52 drives the receiving plate 55 to open and close during the extension and retraction process; when the impact force on the receiving plate 55 is too large, the hinged base 53 drives the spring 532 to press downward along the piston rod, the ball 533 disengages from the semicircular groove 521 and retracts into the rectangular groove 531, and the hinged base 53 slides down on the piston rod by itself, causing the receiving plate 55 to close.

[0055] Reference Figure 8 and Fig. 9 The driving assembly 6 includes a driving motor 61, a gear 62 and a gear ring 63. The driving motors 61 are provided in two numbers and are symmetrically mounted on the inner top of the outer sleeve 512. The two driving motors 61 can more easily drive the gear ring 63 to rotate; the driving assembly 6 drives the inner sleeve 511 to rotate inside the outer sleeve 512.

[0056] The driving motor 61 installed on the top inner side of the outer sleeve 512 drives the gear 62 to rotate, and the gear 62 drives the gear ring 63 meshing therewith to rotate, thereby rotating the inner sleeve 511 fixedly connected to the outer side wall of the gear ring 63, thereby driving the gear 62 and the inner sleeve 511 to rotate, thereby driving the hydraulic rod 52 connected to the bottom of the connecting member 51 to rotate in a circle.

[0057] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 A crushing plate 7 is arranged in an annular array on the side wall of the balanced pressing cylinder 23, and a pulley 24 is arranged on the inner side wall of the central through hole of the balanced pressing cylinder 23.

[0058] A baffle 8 is provided at the end of the piston rod.

[0059] The pulley 24 is set to four, such as Figure 4 Figure 5 As shown, the pulley 24 is arranged on the inner wall of the balance pressing cylinder 23 through an axial ring array, and surrounds the outer wall of the first steel wire rope 2;

[0060] The sum of the widths of the two symmetrical crushing plates 7 is smaller than the length of the balance bar 21, which facilitates the crushing plates 7 to move out of the discharge port or enter the cement silo 1. The crushing plates 7 further crush the aggregated cement accumulated at the discharge port.

[0061] When the breaker 56 knocks down the solidified cement inside the cement silo 1, the solidified cement falls at the discharge port of the cement silo 1, and the crushing plate 7 further crushes the cement accumulated at the discharge port through the rotation of the second steel wire rope 3 and the balanced pressing cylinder 23, so that it flows out of the discharge port faster; when the articulated base 53 is disengaged from the clamping assembly, the articulated base 53 slides freely on the piston rod, and the baffle 8 can prevent the articulated base 53 from being disengaged from the piston rod; when the second steel wire rope 3 drives the balanced pressing cylinder 23 to move up and down, the pulley 24 that runs through the center of the balanced pressing cylinder 23 can make the resistance of the balanced pressing cylinder 23 smaller during the up and down sliding process.

[0062] In this embodiment, a counterweight 22 is installed on the balancing rod 21 which is off-center. When there is no external force blocking the balancing rod 21, the balancing rod 21 can deviate to one side of the counterweight 22 according to its own gravity, thereby achieving the effect of being subsequently moved out from the discharge port of the cement silo 1.

[0063] In this embodiment, four hydraulic rods 52 are provided, and correspondingly, the hinged base 53, the auxiliary rod 54 and the receiving plate 55 are all provided with corresponding numbers, which can prevent that when one or two receiving plates 55 are closed by the impact force of the solidified cement, the other unclosed receiving plates 55 and the breaking hammers 56 installed at the ends of the receiving plates 55 continue to break the solidified cement inside the cement silo 1, thereby ensuring the efficiency of cement cleaning.

[0064] In this embodiment, if only a rod is used to support the breaker 56, when the solidified cement falling from above hits the rotating rod, the rotating rod will be subjected to the tangential force of the solidified cement, causing the rotating rod to stop. If this continues for a long time, it will cause damage to the drive assembly 6. The receiving plate 55 is configured as a long plate from top to bottom, and the shape of the long plate is inclined downward from right to left. The receiving plate 55 receives the solidified cement falling from above, and the inclined surface of the receiving plate 55 from top to bottom always keeps rotating clockwise. When cement falls and hits the receiving plate 55, the clockwise rotation of the receiving plate 55 can be further promoted.

[0065] In this embodiment, four third steel wire ropes 4 are provided to hoist the cleaning assembly 5, which can enhance the pulling stability of the third steel wire ropes 4 during the up and down movement of the cleaning assembly 5.

[0066] In this embodiment, a circular array of pulleys 24 is installed on the inner side of the balancing and pressing cylinder 23, and a first steel wire rope 2 is arranged through a central perforation of the balancing and pressing cylinder 23. When the second steel wire rope 3 drives the balancing and pressing cylinder 23 to move up and down, the balancing and pressing cylinder 23 has smaller resistance when moving up and down due to the rolling of the pulley 24.

[0067] The implementation principle of the cleaning device for cement silo solidified cement in the embodiment of the present application is as follows:

[0068] When cleaning the coagulated cement inside the cement silo 1, under the action of the gravity of the counterweight 22, the balance bar 21 loses balance and tilts to the side where the counterweight 22 is installed, and the first steel wire rope 2 drives the balance bar 21 to move vertically downward and move out from the discharge port at the lower end of the cement silo 1. At this time, the second steel wire rope 3 is started to drive the balance pressing cylinder 23 to move downward, and the balance pressing cylinder 23 contacts the center of the balance bar 21 to restore the balance bar 21 to a horizontal state, and at the same time, the first steel wire rope 2 and the second steel wire rope 3 are started to drive the horizontal balance bar 21 to be clamped on the discharge port, and the balance pressing cylinder 23 always contacts the center of the balance bar 21. The first steel wire rope 2 that runs through the cleaning component 5 remains in a straight state, and its swing amplitude can be reduced when the cleaning component 5 rotates, thereby reducing the probability of collision between the breaker 56 and the inner wall of the cement silo 1.

[0069] Then, the hydraulic rod 52 is started. During the extension and retraction process, the hydraulic rod 52 drives the hinged base 53 to move vertically up and down, and then the hinged auxiliary rod 54 and the receiving plate 55 are opened and closed to different degrees, driving the breaker 56 to contact the solidified cement on the inner side of the cement silo 1. The driving assembly 6 is started to drive the inner sleeve 511 to rotate slowly inside the outer sleeve 512, and the hydraulic rod 52 rotates, so that the breaker 56 contacts the solidified cement on the inner side of the cement silo 1. The breaker 56 cleans the solidified cement on the inner side of the cement silo 1 from bottom to top; the solidified cement falls on the receiving plate 55 and falls downward along the receiving plate 55, and flows out from the discharge port;

[0070] During the extension and retraction of the hydraulic rod 52, when the semicircular groove 521 on the piston rod corresponds to the rectangular groove 531 on the hinged base 53, the ball 533 contacts the semicircular groove 521 under the action of the elastic force of the spring 532. When the impact force of the setting cement on the receiving plate 55 is too large, the ball 533 disengages from the semicircular groove 521. Under the action of the spring 532, the ball 533 retracts into the rectangular groove 531. The hinged base 53 slides down on the piston rod of the hydraulic rod 52 by itself, and the receiving plate 55 closes synchronously to protect the receiving plate 55. During the extension and retraction of the hydraulic rod 52, the clamping assembly is clamped to the hinged base 53 again, which can drive the receiving plate 55 to open again.

[0071] In other embodiments, the four third steel ropes 4 may adopt rigid rods, which have high hardness. Under the action of the rotational force output by the drive assembly 6 and the resistance encountered by the breaker 56 during cleaning, the use of the rigid rods can prevent the four third steel ropes 4 from being entangled together.

[0072] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
