Description

Technical Field

[0001] This utility model relates to the field of pile hole forming technology, and more specifically, to a slag removal device for manually excavated pile holes. Background Technology

[0002] Manually excavated bored piles are a construction method in which pile holes are formed by manual excavation, and concrete is poured into the holes to form the pile foundation. During the construction of manually excavated bored piles, the removal of excavated soil is a crucial step. Traditionally, a hoist is used at the borehole opening, equipped with a winch, to hoist a muck bucket and transport the excavated soil from inside the borehole to a designated removal area outside. For safety, protective railings are usually installed around the borehole opening to prevent workers on the ground from falling into the borehole; they also prevent debris from falling into the borehole and injuring the workers inside. Although protective railings are in place, ground personnel still need to frequently approach the borehole opening from within the railing to observe the situation inside and communicate with the workers inside, thus creating potential safety hazards. Utility Model Content

[0003] This utility model addresses the safety hazards that still exist in existing fence-type structures by providing a slag removal device for manually excavated piles. This device can maintain the protective state of the hole opening throughout the excavation process, avoiding safety accidents caused by operators' probe operation.

[0004] This utility model is achieved through the following technical solution: A manually excavated bored pile muck removal device includes a hanger, a lifting mechanism, and a muck removal bucket. The hook of the lifting mechanism is connected to the muck removal bucket and can lift the muck removal bucket. The hanger includes a hanger body arranged at the borehole opening and a muck removal crossbeam arranged on the top of the hanger body. The lifting mechanism is arranged on the muck removal crossbeam and can move along the muck removal crossbeam, thereby moving the muck removal bucket laterally from the borehole opening to the muck removal area. The manually excavated bored pile muck removal device also includes a protective net that can cover the borehole opening. The protective net is slidably arranged on the hanger body and can slide vertically along the hanger body. The hanger body is also provided with a net frame limiting component that can temporarily position the protective net at a fixed position on the hanger body. The steel rope portion of the lifting mechanism passes through the protective net, and a net frame lifting ring is provided on the steel rope portion, which can lift the protective net when the slag bucket is discharged. The protective net also has a notch, which allows the steel rope portion to detach from the protective net.

[0005] Optionally, the main body of the hanger includes several columns, each column having a groove, and the protective net is connected to several rollers, which are capable of moving within the groove.

[0006] Optionally, the space frame limiting assembly includes a partition, a first guide plate, a second guide plate, and a limiting plate. The partition is arranged in the groove to divide the groove into two channels capable of moving the rollers. A limiting plate is arranged in one of the channels, and the limiting plate can rotate between a vertical and a horizontal state. The bottom end of the partition is connected to the first guide plate, and a torsion spring is arranged between the first guide plate and the partition to keep the first guide plate in contact with one side of the groove, thereby guiding the rollers to the channel where the limiting plate is arranged. The top end of the partition is connected to the second guide plate, and a torsion spring is arranged between the second guide plate and the partition to keep the second guide plate in contact with the other side of the groove.

[0007] Optionally, the column is made of channel steel or I-beam.

[0008] Optionally, the notch portion adopts a flared structure in the shape of a trumpet.

[0009] Optionally, the lifting mechanism is a winch.

[0010] Optionally, the notch extends from the side of the protective net to the center of the protective net.

[0011] The technical solution of this utility model has at least the following beneficial effects: This utility model's manual excavation pile muck removal device, by arranging a protective net at the hole opening, can keep the hole opening covered during the excavation process, ensuring the safety of the operation even if an operator is peering through the net; at the same time, the safety net can be temporarily attached to the main body of the hoisting frame during hoisting without affecting the muck removal and hoisting of the muck bucket, making the operation simple and convenient.

Detailed Implementation

[0014] Reference Figure 1 The manually excavated bored pile muck removal device of this embodiment includes a hanger 10, a lifting mechanism 20, and a muck removal bucket 30. The lifting mechanism 20 can be a conventional winch. The hook of the lifting mechanism 20 is connected to the muck removal bucket 30, enabling it to lift the muck removal bucket 30. The hanger 10 includes a hanger body arranged at the borehole opening and a muck removal crossbeam 12 arranged on top of the hanger body. The muck removal crossbeam 12 generally extends out of the hanger body, and an area outside the hanger body is designated as the muck removal area, where the lifted muck is dumped. The lifting mechanism 20 is arranged on the muck removal crossbeam 12 and can move along the muck removal crossbeam 12, thereby moving the muck removal bucket 30 laterally from the borehole opening to the muck removal area. The main body of the hanger in this embodiment includes several columns 11. Generally, three or four columns 11 are selected. In this embodiment, four columns 11 are selected. The column 11 is made of I-beams or channel steel. The bottom of the column 11 is fixed to the ground by concrete foundation and buried bolts, etc. The top is arranged with connecting components to form an integral structure. At the same time, a canopy can be laid on the top for rain protection and sunshade.

[0015] Reference Figure 1 , Figure 2 The slag removal device for manually excavated bored piles also includes a protective net 40, which can cover the borehole opening. The protective net 40 is slidably arranged on the main body of the hanger and can slide vertically along the main body of the hanger. This is mainly achieved by setting a trough on the column 11, with several rollers 41 connected to the protective net 40, and the rollers 41 can move in the trough. The column 11 forms a guiding structure, allowing the protective net 40 to move vertically along the column 11.

[0016] The steel rope section 21 of the lifting mechanism 20 passes through the protective netting 40, and a net frame lifting ring is provided on the steel rope section 21. The net frame lifting ring is a ring-shaped component arranged near the slag discharge bucket 30 and fixed to the steel rope section 21. The ring component can be designed with a disc structure to increase the contact area. The outer diameter can be larger than the rope hole structure on the protective netting 40. This allows the protective netting 40 to be lifted when the slag discharge bucket 30 exits the hole, thus allowing the protective netting 40 to move and rise along the column 11. The protective netting 40 also has a notch section 42 that connects to the rope hole, allowing the steel rope section 21 to detach from the protective netting 40. The notch section 42 extends from the side of the protective netting 40 to its center, ensuring that the steel rope section 21 is located in the center of the hole during hoisting. At the same time, the notch section 42 adopts a flared, trumpet-shaped structure, allowing it to easily enter the notch section 42 when the slag discharge bucket 30 returns to the center of the hole after dumping the slag.

[0017] Reference Figure 3 , Figure 4A mesh frame limiting assembly 50 is also arranged on the main body of the hanger, which can temporarily position the protective net 40 in a fixed position on the main body of the hanger. The mesh frame limiting assembly 50 includes a partition 53, a first guide plate 52, a second guide plate 54, and a limiting plate 51. The partition 53 is arranged in the trough and is used to divide the trough into two channels that can move the roller 41. The limiting plate 51 is arranged in one of the channels and can be rotated between a vertical and a horizontal state. The bottom end of the partition 53 is connected to the first guide plate 52. A torsion spring is arranged between the first guide plate 52 and the partition 53 to keep the first guide plate 52 in contact with one side of the trough, so as to guide the roller 41 to the channel where the limiting plate 51 is arranged. The top end of the partition 53 is connected to the second guide plate 54. A torsion spring is arranged between the second guide plate 54 and the partition 53 to keep the second guide plate 54 in contact with the other side of the trough.

[0018] When the lifting mechanism 20 retracts the steel rope section 21, thereby lifting the slag discharge bucket 30 out of the orifice, it will rise together with the protective net 40 via the net frame lifting ring. When the roller 41 connected to the protective net 40 reaches the end face of the partition 53, it will first be guided by the first guide plate 52 and guided into the channel where the limit plate 51 is set. The limit plate 51 adopts a one-way rotation structure, so the roller 41 can move and pass over the limit plate 51. After the roller 41 passes over the limit plate 51, the limit plate 51 will deflect to a vertical state due to gravity. This controls the lifting mechanism 20 to descend a certain height, and the roller 41 of the protective net 40 is restricted and fixed at that height position by the limit plate 51. At this time, the lifting mechanism 20 is controlled to move along the slag discharge beam 12, and the steel rope section 21 can exit the protective net 40 from the notch section 42 and then go to the slag discharge area to perform the dumping work.

[0019] After the dumping is completed, the lifting mechanism 20 is moved along the slag discharge beam, returning to the center of the protective net 40 from the notch 42. Then, the lifting mechanism 20 continues to rise, causing the protective net 40 to continue moving. Since the second guide plate 54 is elastically pressed against the side of the trough, the elastic force can overcome the resistance, allowing the roller 41 to pass over the second guide plate 54. When the roller 41 rises above the second guide plate 54, the second guide plate 54 returns to its position against the trough under the action of the torsion spring. Then, the lifting mechanism 20 descends, and the protective net 40 follows. Guided by the second guide plate 54, the roller 41 of the protective net 40 enters another channel and continues to descend. At the position of the first guide plate 52, the elastic force of the first guide plate 52 cannot resist the weight of the protective net 40, so the protective net 40 can continue to descend with the slag discharge bucket 30, finally stopping at the orifice to achieve protection.
