Technical Field
[0001] This utility model relates to the field of crushed stone pile technology, and in particular to a protective device for crushed stone pile construction. Background Technology
[0002] Crushed stone piles are formed by drilling holes in soft soil using processes such as vibration and impact, filling them with crushed stone, and compacting it to form a pile body. This pile body, together with the soil between the piles, forms a composite foundation. Construction safety devices are protective facilities installed in construction sites, such as buildings, to prevent personal injury, equipment damage, and reduce the risks of falls from heights and electric shocks. These devices include safety helmets, guardrails, and leakage protection devices, which can ensure construction safety and orderly processes.
[0003] Some crushed stone pile protection devices are key supporting components adapted to crushed stone pile construction processes such as vibro-compaction and pipe driving. The core consists of a guide and positioning component, an anti-collapse hole protection component, and a crushed stone filling control component. During operation, the guide and positioning component ensures the verticality of the pile body, the anti-collapse hole component maintains the stability of the hole formation, and the filling control component precisely regulates the amount and speed of crushed stone filling. Ultimately, it achieves the purpose of protecting the quality of pile formation, reducing damage to construction equipment, and reducing disturbance to the surrounding environment. It is widely used in soft soil foundation reinforcement projects.
[0004] In existing technologies, some protective devices for crushed stone piles have imperfect safety designs, making it difficult to provide rapid protection in case of emergencies. They also have slow anti-fall response speeds and lack efficient triggering mechanisms, relying heavily on gravity and inertia to initiate locking actions, which can easily lead to increased displacement during falls. Therefore, a protective device for crushed stone pile construction is proposed to solve the above problems. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] A protective device for the construction of crushed stone piles, referring to Figures 1 to 3The system includes a frame 1, which supports the fall arrest mechanism 3 and the quantitative feeding mechanism 5. A steel wire rope 2 is fixedly connected to the top of the frame 1. The steel wire rope 2 is used to adjust the depth of the crushed stone pile construction and drives the fall arrest mechanism 3 to move up and down during construction. The fall arrest mechanism 3 is fixedly connected to the bottom of the steel wire rope 2. The fall arrest mechanism 3 ensures construction safety and can quickly trigger a locking function in case of accidents such as breakage of the steel wire rope 2. The quantitative feeding mechanism 5 is fixedly connected to the top of the frame 1 and controls the amount and speed of crushed stone feeding. The fall arrest mechanism 3 includes a connector 31, which is the connection center between the fall arrest mechanism 3 and the steel wire rope 2, enabling force transmission. The top of the connector 31 is fixedly connected to a steel wire rope 2. At the bottom of the wire rope 2, a sliding rod 33 is fixedly connected to the bottom of the connector 31. The sliding rod 33 can slide along the support component 32 in the event of an accidental fall and is the main structure for triggering the anti-fall locking. The support component 32 is slidably connected to the outside of the sliding rod 33. The support component 32 provides guidance for the sliding of the sliding rod 33 and also provides an installation base for the rotating component 36 and the locking block 37. A connecting block 34 is fixedly connected to the bottom of the sliding rod 33 for connecting the rotating component 36 and converting the sliding displacement of the sliding rod 33 into the rotational power of the rotating component 36. A spring plate 35 is provided on the outside of the sliding rod 33. Under normal circumstances, it is compressed and stores energy. When an accidental fall occurs, the spring plate 35 quickly releases the elastic potential energy, causing the sliding rod 33 to slide downward. Specifically, the frame 1 is used to support the entire device, the wire rope 2 is used to adjust the construction depth and drive the anti-fall mechanism 3 to rise and fall, the connector 31 transmits force, and when the wire rope 2 breaks accidentally, the spring plate 35 releases energy and drives the sliding rod 33 to slide down, thereby driving the rotating component 36 to rotate, thereby causing the locking block 37 to engage with the rack 38. Rotating components 36 are rotatably connected to the front and rear sides of the connecting block 34, which can convert the linear movement of the connecting block 34 with the sliding rod 33 into its own rotational movement, thereby driving the locking block 37 to engage with the rack 38. The other end of the rotating component 36 is rotatably connected to the locking block 37, which rotates under the drive of the rotating component 36. In case of an accident, it tightly engages with the rack 38 to achieve the anti-fall function. The top of the frame 1 is fixedly connected to the rack 38, which works in conjunction with the locking block 37. When the locking block 37 engages in the tooth groove of the rack 38, it forms a mechanical lock to restrict the movement of the anti-fall mechanism 3. The support component 32 includes a horizontal connecting plate 321, which provides a sliding guide for the sliding rod 33. The interior of the horizontal connecting plate 321 is slidably connected to the exterior of the sliding rod 33. The bottom ends of the horizontal connecting plate 321 are fixedly connected to vertical Plate 322 provides a rotation point for the locking block 37, allowing the locking block 37 to rotate around the vertical plate 322. The rotating assembly 36 includes a first rotating plate 361, which can rotate with the movement of the connecting block 34. The interior of the first rotating plate 361 is rotatably connected to the exterior of the connecting block 34. The interior of the first rotating plate 361 is rotatably connected to a second rotating plate 362, which can transmit the rotational power of the first rotating plate 361 to the locking block 37, thereby driving the locking block 37 to perform locking and unlocking actions. The bottom of the connector 31 is fixedly connected to a vibrator 4, and the top of the frame 1 is fixedly connected to a cab 6. The operator operates from inside the cab 6 to move the entire structure to the designated position for work. The exterior of the locking block 37 is rotatably connected to the interior of the support assembly 32. This connection method allows the locking block 37 to rotate flexibly around the support assembly 32. Specifically, the horizontal connecting plate 321 guides the sliding rod 33. The sliding rod 33 slides down, causing the connecting block 34 to move. This causes the first rotating plate 361 of the rotating assembly 36 to rotate with the connecting block 34, which in turn causes the second rotating plate 362 to rotate. This causes the locking block 37 to rotate around the vertical plate 322 of the support assembly 32 and engage with the rack 38, forming a mechanical lock to prevent falling and improve safety and ease of operation.
[0013] Reference Figure 1 and Figure 4The quantitative feeding mechanism 5 includes a support column 51, which provides support for the quantitative feeding mechanism 5. The bottom of the support column 51 is fixedly connected to the top of the frame 1. A connecting column 52 is fixedly connected to the outer right side of the support column 51, which fixes the storage bin 53 through the connection with the support column 51. The storage bin 53 is fixedly connected to the adjacent side of the two connecting columns 52, which is used to store the crushed stone required for construction. A buffer plate 54 is fixedly connected inside the storage bin 53, which plays a role in blocking and buffering the falling crushed stone and preventing the crushed stone from directly hitting the gate 510. Fixed connecting frames 55 are fixedly connected to the front and rear sides of the storage bin 53, which are used to install fixed cylinders 56. The cylinder 56 is fixedly connected to the bottom of the fixed connecting frame 55. The cylinder 56 is the power source of the quantitative feeding mechanism 5, which drives the connecting ring 57 and the rotating connecting plate 58 to extend and retract. The driving end of the cylinder 56 is fixedly connected to the connecting ring 57, connecting... A rotating connecting plate 58 is fixedly connected to the bottom of the connecting ring 57. The rotating connecting plate 58 is used to drive the driven block 59 to rotate, thereby realizing the power direction transmission. The driven block 59 is rotatably connected inside the two rotating connecting plates 58, which is used to drive the gate 510 to realize the opening and closing action. The gate 510 is fixedly connected to the adjacent side of the two driven blocks 59. The gate 510 realizes the opening and closing of the outlet of the storage bin 53 through the opening and closing action, thereby controlling the amount of crushed stone discharged. The driven plate 511 is fixedly connected to the outside of the gate 510. The driven plate 511 provides a fulcrum for the rotation of the gate 510, ensuring that the gate 510 can rotate stably around the fixed plate 512. The fixed plate 512 is rotatably connected to the outside of the driven plate 511. Through the rotatable connection with the driven plate 511, the smooth opening and closing action of the gate 510 is ensured. The two fixed plates 512 are fixedly connected to the outside of the storage bin 53. Specifically, the support column 51 and the connecting column 52 are used to fix the storage bin 53, the buffer plate 54 is used to buffer the crushed stone to prevent it from impacting the gate 510 and causing damage, the cylinder 56 drives the connecting ring 57 and the rotating connecting plate 58, and drives the driven block 59 to make the gate 510 rotate around the fixed plate 512. By opening and closing, the amount of crushed stone fed is controlled, which improves the efficiency and reliability of construction.
[0014] The implementation principle of this application embodiment is as follows: When the crushed stone pile is being constructed, the wire rope 2 can drive the anti-fall mechanism 3 to move up and down. Since the connector 31 of the anti-fall mechanism 3 is fixedly connected to the wire rope 2, it drives the sliding rod 33 and the support component 32 to move together. If the wire rope 2 breaks, the spring plate 35 will release the elastic force, causing the sliding rod 33 to slide down. At this time, the connecting block 34 will rotate in conjunction with the first rotating plate 361 and the second rotating plate 362, thereby causing the locking block 37 to engage with the rack 38, thus achieving the anti-fall effect. When the vibratory compactor 4 is in operation, when it is necessary to add crushed stone into the hole, the loader is used to fill the storage bin 53 with crushed stone at one time. The buffer plate 54 in the storage bin 53 can buffer the impact force of the falling crushed stone and prevent the crushed stone from damaging the gate 510. Then, the cylinder 56 drives the connecting ring 57 and the rotating connecting plate 58 to extend and retract, causing the driven block 59 to rotate, which in turn causes the gate 510 to rotate around the fixed plate 512 through the driven plate 511. When the amount of crushed stone required for each vibratory compaction is met, the cylinder 56 is controlled again to reset the gate 510, thereby closing the storage bin 53 and stopping the feeding of crushed stone.
