Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit construction technology, specifically a suspended walkway for deep foundation pits. Background Technology

[0002] With the continuous development of the construction industry, the depth of foundation pit excavation is constantly being refreshed. Currently, the commonly used pedestrian walkways for foundation pit construction mainly adopt ground-mounted steel pipe scaffolding and lay steel or wooden ladders. The walkway is supported by the bottom of the foundation pit. It can only be erected after the foundation pit is excavated to the design bottom elevation and the walkway foundation construction is completed, which causes inconvenience to the passage of construction personnel.

[0003] Patent No.: CN213173735U, a tool-type suspended walkway for deep foundation pits, including a capping beam foundation and a support component located on the upper part of the capping beam foundation. A zigzag ladder is provided on the left side of the support component. The support component includes two irregularly shaped rods arranged in a symmetrical front-to-back structure. A fixing plate is provided between the top of the two irregularly shaped rods and between the right sides of the two irregularly shaped rods. Fixing components are provided at the bottom and left side of the fixing plate. This utility model provides a sliding support plate at the handrail position in the middle of the zigzag ladder, so that construction workers do not need to carry or bear objects by hand when going up and down the passage. They can simply pull the support plate to transport the objects, saving time and effort, and making it simple and quick.

[0004] The above-mentioned device still has certain defects in actual production and use: the above-mentioned device lacks a structure for stable connection between the walkway and the bottom of the foundation pit during use, which makes the walkway extremely unstable when suspended on the foundation pit, posing certain safety hazards to construction personnel. Based on the shortcomings of existing technology, this utility model designs a suspended walkway for deep foundation pits. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a suspended walkway for deep foundation pits, which has the advantage of ensuring a stable connection between the walkway and the bottom of the foundation pit.

[0006] This utility model provides the following technical solution: a suspended walkway for deep foundation pits, comprising a steel pipe frame, wherein the steel pipe frame is welded from multiple steel pipes, and two of the steel pipes of the steel pipe frame are provided with connecting structures inside, the two connecting structures including rotating shafts, connecting blocks being rotatably installed inside the two rotating shafts, a throttle handle being installed on the outer surface of the connecting blocks, a threaded rod being welded to one side of the outer surface of the connecting blocks, a threaded sleeve being threadedly installed on the outer surface of the threaded rod, the threaded sleeve being movably snapped into the inner wall of the steel pipe, a conical head being installed at one bottom end of the threaded sleeve, and four sleeves being provided at the bottom of the steel pipe frame.

[0007] As a preferred embodiment of this utility model, the steel pipe frame is provided with a walkway staircase inside, and the steel pipe frame is provided with a platform inside.

[0008] As a preferred embodiment of this utility model, multiple reinforcing steel pipes are welded between two steel pipes of the steel pipe frame.

[0009] As a preferred embodiment of this utility model, suspension components are provided on both sides of the outer surface of the steel pipe frame.

[0010] As a preferred embodiment of this utility model, a cover plate structure is installed on the top of the steel pipe frame, and the cover plate structure includes four connecting rods.

[0011] As a preferred embodiment of this utility model, a first cover plate is installed on the top of the four connecting rods, and two support rods are installed on one side of the outer surface of the first cover plate.

[0012] As a preferred embodiment of this utility model, a second cover plate is provided on the top of the two support rods, the second cover plate is hinged to the first cover plate, and a top handle is provided on the top of the second cover plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This suspended walkway for deep foundation pits, through a connecting structure, allows the second cover plate to be opened when connecting the device to the bottom of the foundation pit. At this time, the operator stands on the platform and turns the handle, causing the connecting block to drive the threaded rod to rotate in the steel pipe frame. Since the threaded sleeve is movably snapped into the steel pipe frame and threadedly connected to the threaded rod, the rotation of the threaded rod can drive the threaded sleeve to move horizontally on its outer surface, thereby allowing the conical head to penetrate into the foundation pit ground, thus completing the connection with the bottom of the foundation pit, ensuring the stability of the device and avoiding safety hazards to construction personnel.

[0015] 2. This suspended walkway for deep foundation pits, through the setting of the cover plate structure, allows construction workers to hold the top handle and push the second cover plate open upwards during normal weather to provide more sunlight into the device, thereby providing better visibility inside the device. During rainy weather, the second cover plate can be reset and closed, thereby reducing the amount of rainwater entering the device. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 A suspended walkway for deep foundation pits includes a steel pipe frame 1, which is welded from multiple steel pipes. Two of the steel pipes in the steel pipe frame 1 have a connecting structure 4 inside. The two connecting structures 4 include a rotating shaft 41. A connecting block 42 is rotatably installed inside the two rotating shafts 41. A handle 43 is installed on the outer surface of the connecting block 42. A threaded rod 44 is welded to one side of the outer surface of the connecting block 42. A threaded sleeve 45 is threadedly installed on the outer surface of the threaded rod 44. The threaded sleeve 45 is movably snapped into the inner wall of the steel pipe. A conical head 46 is installed at one bottom end of the threaded sleeve 45. Four sleeves 7 are provided at the bottom of the steel pipe frame 1.

[0024] Please see Figure 1-3 The steel pipe frame 1 has a walkway staircase 2 inside, and a platform 3 inside. Multiple reinforcing steel pipes 6 are welded between two steel pipes of the steel pipe frame 1. Suspension components 8 are installed on both sides of the outer surface of the steel pipe frame 1.

[0025] The steel pipe frame 1 is reinforced and fixed by the reinforcing steel pipe 6. The steel pipe frame 1 can be fixed to the inner wall of the pit opening by the setting of the suspension component 8.

[0026] Please see Figure 1-5A cover plate structure 5 is installed on the top of the steel pipe frame 1. The cover plate structure 5 includes four connecting rods 51. A first cover plate 52 is installed on the top of the four connecting rods 51. Two support rods 53 are installed on one side of the outer surface of the first cover plate 52. A second cover plate 54 is provided on the top of the two support rods 53. The second cover plate 54 is hinged to the first cover plate 52. A top handle 55 is provided on the top of the second cover plate 54.

[0027] In normal weather, construction workers can hold the top handle 55 and push the second cover plate 54 upwards to provide more sunlight into the device and thus provide better visibility inside. In rainy weather, the second cover plate 54 can be reset and closed to reduce rainwater entering the device.

[0028] Working principle: When a suspended walkway for deep foundation pits is used, in the initial state, the steel pipe frame 1 is first fixed to the inner wall of the foundation pit opening by the suspension assembly 8. At the same time, the second cover plate 54 is opened. At this time, the operator stands on the platform 3 and turns the handle 43, so that the connecting block 42 drives the threaded rod 44 to rotate in the steel pipe frame 1. Since the threaded sleeve 45 is movably snapped into the steel pipe frame 1 and threadedly connected to the threaded rod 44, when the threaded rod 44 rotates, it can drive the threaded sleeve 45 to move horizontally on its outer surface, so that the conical head 46 can be driven into the foundation pit ground, thereby making the steel pipe frame 1 more stable. In normal weather, the construction personnel can hold the top handle 55 and push the second cover plate 54 open to provide more sunlight into the device, thereby providing better visibility inside the device. In rainy weather, the second cover plate 54 is reset and closed, thereby reducing rainwater from entering the device.
