Description

Technical Field

[0001] This utility model relates to the field of bored pile construction technology, specifically to a deep hole operation channel. Background Technology

[0002] In construction projects such as water conservancy and hydropower, bridges, mines, and subways, it is often necessary to construct deep wells or holes (such as ventilation shafts, vertical shafts, and pile holes) as work or passageways. To meet the vertical transportation needs of personnel, equipment, and materials, work passageways need to be set up inside the deep holes.

[0003] Currently, fixed steel ladders are used as working passages in deep boreholes. This traditional ladder has several drawbacks: First, its structure is usually fixed, with no adjustable length or width, making it unsuitable for holes of different depths and diameters, resulting in poor versatility. Different specifications of ladders need to be designed and manufactured for different projects, leading to resource waste and increased costs. Second, fixed ladders are bulky, making transportation and handling extremely inconvenient, and difficult to install in narrow construction sites. Third, to ensure operational safety, ladders usually require safety cages. Traditional cages are mostly rigid welded structures, fixedly connected to the ladder, which not only increases the complexity and weight of the overall structure but also requires more space for storage and transportation. Furthermore, in manually excavated bored pile construction, traditional methods of access include rope climbing, using earthmoving equipment, or climbing along the pile wall, but these pose significant safety hazards. Rope climbing: poor stability, prone to falls due to fatigue or slippery conditions. Earthmoving equipment: unmanned design, insufficient structural strength, prone to overturning or breakage accidents. Climbing along the pile wall: When the pile wall is smooth or the soil is loose, it is very easy to slip and fall, and there is a lack of protective measures. Utility Model Content

[0004] The present invention aims to overcome the defects in the prior art and provide a deep hole operation channel with a simple structure and high safety, which can be used for different hole diameters and depths.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a deep hole operation channel, including several detachable ladders, with a connecting structure between adjacent ladders, and the width of the ladders is adjustable; each ladder is equipped with a protective cage to form a protective space, and a hinge is provided between the protective cage and the ladder.

[0006] As a preferred embodiment of this utility model, the ladder includes two parallel support rods, and a plurality of ladder rods evenly distributed along its length are provided between the two support rods, and the ladder rods are telescopic structures.

[0007] As a preferred embodiment of this utility model, the connecting structure is configured as a connector for connecting two adjacent ladders, and the two ends of the connector are provided with bolts for fixed connection with the support rod.

[0008] As a preferred embodiment of this utility model, two connectors are provided, and they are respectively located at the ends of two parallel support rods.

[0009] As a preferred embodiment of the present invention, the cage includes several protective rings evenly distributed along the length of the ladder, and steel wire ropes are connected between the protective rings, with the steel wire ropes arranged along the length of the ladder.

[0010] As a preferred embodiment of this utility model, the protective ring has an arc-shaped structure, and the hinge is provided at the end of the protective ring.

[0011] As a preferred embodiment of this utility model, the support rod is provided with a fixing member, and the hinge is connected to the guard ring and the fixing member.

[0012] As a preferred embodiment of this utility model, the top of the cage is provided with a handle for raising and lowering the cage.

[0013] As a preferred embodiment of this utility model, it also includes an orifice base, on which a through hole is formed, and a crossbar is provided on the orifice base, and the ladder is connected to the crossbar.

[0014] In a preferred embodiment of this utility model, the fixing member is provided with a connecting plate, which is connected to the crossbar.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up several detachable ladder units and connecting them in series using a connecting structure, the number of ladders can be flexibly increased or decreased according to the actual depth of the deep hole, realizing free adjustment of the length. Furthermore, the ladder is set to have an adjustable width structure. This design allows a single ladder unit to adapt to holes of different diameters within a certain range, greatly improving the versatility and adaptability of the product and reducing the manufacturing cost of special equipment.

[0016] 2. The cage is connected to the ladder via hinges, enabling it to be tilted and retracted. A handle at the top allows operators to easily lower or raise the cage from the ground or work platform. In the retracted state, the space occupied by the ladder system is greatly reduced, facilitating passage through narrow areas; in the lowered state, it creates an effective safety protection space, ensuring personnel safety. The steel wire rope connection to the protective ring structure ensures safety and strength while reducing overall weight and increasing structural flexibility.

[0017] 3. Furthermore, the detachable modular design breaks down the massive ladder system into multiple smaller units, significantly reducing the weight and volume of individual components and making transportation and on-site handling more convenient. Construction workers can easily insert the units one by one into the holes and assemble them internally, reducing the difficulty and risk of installation work.

[0018] 4. Furthermore, specialized connectors and bolts are used to connect adjacent ladders, ensuring the overall strength and stability of the connected ladder sections. By setting up orifice bases and crossbars and fixing them to the connecting plates on the ladders, the entire work passage system can be quickly and securely installed at the orifice, ensuring the safety and reliability of the entrance.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a deep hole working channel includes several detachable ladders 1, with a connecting structure 4 between adjacent ladders 1, and the width of the ladders 1 is adjustable; the ladders 1 are provided with a protective cage 2 to form a protective space, and a hinge 3 is provided between the protective cage 2 and the ladders 1.

[0022] Furthermore, this device is designed for deep-hole operations, employing a modular, foldable structure. It consists of a detachable aluminum alloy ladder 1 and a protective cage 2 hinged to the ladder 1. Each section of the ladder 1 is approximately 100cm long, and the protective cage 2 has a protective height of approximately 100cm. The main body of the ladder 1 is made of high-strength aluminum alloy profiles, balancing lightweight design with load-bearing requirements (≥300kg). Multiple ladders 1 can be quickly assembled via a connecting structure 4, adapting to different hole depths. The protective cage 2 is connected to the ladder 1 via hinges 3. When unfolded, it forms a fully enclosed protective space to prevent personnel from falling; when folded, it fits snugly against the side wall of the ladder 1, reducing transport volume. In the folded state, the volume is reduced to 1 / 5 of the unfolded state, allowing for manual transport to the work site and assembly within 10 minutes, significantly improving the safety and efficiency of deep-hole operations.

[0023] The ladder 1 includes two parallel support rods 101, and a number of ladder rods 102 evenly distributed along their length are provided between the two support rods 101. The ladder rods 102 are telescopic structures. Furthermore, the ladder rods 102 are vertically connected to the support rods 101, and the ladder rods 102 can extend and retract along their length, thereby adjusting the width of the ladder 1 to suit holes of different diameters.

[0024] The connecting structure 4 is configured as a connector 401 for connecting two adjacent ladders 1. The connector 401 has bolts 402 at both ends for fixed connection with the support rod 101. Furthermore, there are two connectors 401, which are located at the ends of two parallel support rods 101 respectively. The connector 401 is a plate-shaped structure and is connected to the support rod 101, thereby connecting and fixing the corresponding support rods 101 of the two ladders 1. By the cooperation of the bolts 402 and the connector 401, the two adjacent ladders 1 are connected and fixed, thereby increasing the length of the ladder 1 and making it suitable for holes of different depths.

[0025] The protective cage 2 includes several protective rings 201 evenly distributed along the length of the ladder 1. Steel wire ropes 202 are connected between the protective rings 201 and are arranged along the length of the ladder 1. Furthermore, the protective rings 201 have an arc-shaped structure, and hinges 3 are set at the ends of the protective rings 201. The protective rings 201 are made of deformable material. When the width of the ladder 1 changes, the protective rings 201 deform accordingly. The protective rings 201 are hinged to the ladder 1 through the hinges 3. The top of the steel wire ropes 202 is connected to the opening. After the protective rings 201 are unfolded, they form a vertical channel with the ladder 1, thus providing protection for construction personnel when climbing the ladder 1. The steel wire ropes 202 also achieve dynamic stability of the vertical channel, adapting to the conditions of slight deformation of the hole wall or soft soil foundation.

[0026] The support rod 101 is provided with a fixing member 1011. The hinge member 3 is connected to the guard ring 201 and the fixing member 1011. Furthermore, the fixing member 1011 has an L-shaped structure. One vertical side of the fixing member 1011 is fixedly connected to the support rod 101, and the other side is connected to the end of the guard ring 201 through the hinge member 3, so that the guard ring 201 can rotate on the fixing member 1011, thereby realizing the hinge between the guard ring 201 and the support rod 101. The hinge member 3 is a bolt and a nut. The bolt passes through the fixing member 1011 and the guard ring 201, and the nut is threadedly connected to the end of the bolt and abuts against the guard ring 201, thereby realizing the hinge between the guard ring 201 and the fixing member 1011.

[0027] The top of the cage 2 is provided with a handle 203 for raising and lowering the cage 2. Furthermore, the handle 203 is located at the top of the cage 2 and is connected to the protective ring 201. The raising and lowering of the cage 2 is controlled by the handle 203.

[0028] It also includes an orifice base 6, on which a through hole 601 is formed, and a crossbar 5 is provided on the orifice base 6. The ladder 1 is connected to the crossbar 5. Furthermore, the orifice base 6 is located at the end of the hole, and the crossbar 5 is fixedly connected to the orifice base 6. The length of the crossbar 5 is greater than the diameter of the through hole 601. The ladder 1 is fixedly connected to the crossbar 5 and enters the hole through the through hole 601, thereby realizing the installation of the ladder 1.

[0029] The fastener 1011 is provided with a connecting plate 1012, which is connected to the crossbar 5. Furthermore, the connecting plate 1012 is fixedly connected to the fastener 1011, and the connecting plate 1012 is fixedly connected to the crossbar 5 by bolts, thereby realizing the connection between the ladder 1 and the crossbar 5.
