Description

Technical Field

[0001] This utility model relates to the field of manually excavated pile technology, and in particular to a protective device for workers operating manually excavated piles. Background Technology

[0002] Manual borehole excavation is a common construction method in civil engineering, building construction, and municipal engineering, mainly used for pile foundation drilling, pipeline laying, and surveying and sampling. This process has advantages such as simple equipment, strong adaptability, and high-quality borehole formation. However, significant safety hazards exist during the bottom cleaning stage after borehole formation, which urgently need to be addressed.

[0003] The current work process is as follows: After the borehole is excavated to the designed depth, a large amount of accumulated soil and gravel will remain at the bottom. Workers are transported to the bottom of the borehole using hoisting equipment such as winches or tripods, while soil collection buckets (or hoisting buckets) are also hoisted down into the well. Workers repeatedly shovel the accumulated soil into the collection buckets at the bottom of the borehole. Once the buckets are full, they are hoisted out and emptied by personnel above ground. This process is repeated until the bottom of the borehole is completely cleared.

[0004] The existing operating method has the following main defects and risks: When workers are shoveling soil at the bottom of the hole, their heads and upper bodies are completely exposed below the entire hole wall. Due to the disturbance of the soil around the hole wall caused by the excavation work, or the presence of joints or loose soil, small rocks or loose soil often fall from above the hole wall. Workers can not effectively protect themselves from the impact of falling rocks from above and the sides with only their safety helmets, which can easily cause personal injury and poses a serious safety hazard.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A protective device for workers operating manually excavated bored piles includes a shield, a guide rail, and a support. The support is arranged in an arc shape. The shield is located at one end of the support. The guide rail is detachably connected to the inner wall of the manually excavated bored pile. A guide block is provided at one end of the support. A sliding groove is provided on the guide rail. The support is slidably connected to the sliding groove through the guide block.

[0007] Preferably, one end of the shield is provided with a lifting lug for connecting to the crane.

[0008] Preferably, the shielding plate has an arc-shaped cross-section, and the protruding end of the shielding plate faces outward of the manually dug pit pile.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Example like Figures 1-3 , Figure 5 , Figure 6 As shown, a protective device for workers operating manually excavated piles includes a shield 1, a support 2, and a guide rail 9. The support 2 is a stable arc-shaped frame structure formed by welding several metal rods together. This arc-shaped frame can be adapted to common circular pile holes and provides sufficient space for internal operations.

[0022] The shielding plate 1 is fixedly installed at the top of the bracket 2. The main body of the shielding plate 1 is designed with an arc-shaped cross-section, and its convex surface faces the pile opening of the manually excavated pile. The purpose of this specific arc-shaped design is that when rocks or soil fall from the hole wall, they will first impact the convex arc surface of the shielding plate 1, and then slide down the slope to both sides of the bottom of the hole by their own weight, thereby preventing them from accumulating on top of the shielding plate 1 and effectively eliminating the risk of additional load or reduced protective effect due to the accumulation of debris.

[0023] The edge of the shielding plate 1 closest to the borehole wall is also designed as an arc shape consistent with the curvature of the pile hole, so that it can maintain a small and uniform gap with the borehole wall, maximizing the protection area and avoiding interference with the uneven borehole wall. The shielding plate 1 is made of metal plate or high-strength engineering plastic with certain strength and toughness, and can withstand the impact of falling rocks.

[0024] A lifting lug 5 is provided at the center or symmetrical position on the upper surface of the shielding plate 1. The lifting lug 5 has a pin hole for connecting with the hook of the crane to realize the lifting and lowering of the device in the pile hole.

[0025] The outer contour of the support 2, located near the borehole wall, is also designed to be arc-shaped to match the curvature of the borehole wall. This design allows the support 2 to maintain smooth contact or a small gap with the borehole wall when it moves up and down inside the borehole or moves slightly with personnel, greatly reducing the risk of scratches, collisions, or jamming, while also minimizing disturbance to the stability of the borehole wall.

[0026] The guide rail 9 has a ring-shaped structure, and its curvature matches that of the inner wall of the manually excavated bored pile. It is detachably fixed to the inner wall of the pile hole. Specifically, several connecting plates are provided on the side of the guide rail 9 facing the hole wall. The shape of the connecting plates conforms to the curved surface of the hole wall, and each connecting plate has an installation hole. Anchor rods pass through the installation holes and are anchored in the soil layer of the hole wall, thereby achieving reliable fixation of the guide rail 9 to the inner wall of the pile hole. The advantage of this design is that as the manually excavated bored pile is dug downwards, the workers can remove the anchor rods, lower the entire guide rail 9 to the new working depth, and reinstall it, so that the protective device can continuously provide protection for the working face at different depths.

[0027] A guide block 21 is fixedly mounted on one end of the bracket 2 near the guide rail 9 by welding or threaded connection. The guide rail 9 has an annular groove 92, preferably T-shaped in cross-section. The guide block 21 is shaped to fit into the T-shaped groove 92, allowing it to be inserted and slide smoothly. The guide rail 9 has a connection port on its circumference, which partially breaks the guide rail 9, and its width is greater than the width of the guide block 21. This design allows the bracket 2 to be inserted and removed from the guide block 21 through this connection port, enabling quick assembly and disassembly from the guide rail 9. The bracket 2 is slidably connected to the guide rail 9 through the cooperation of the guide block 21 and the groove 92.

[0028] A lifting ring 91 is also provided on the guide rail 9. The crane hook is connected to the lifting ring 91, which can suspend the guide rail 9 as a whole, making it easy to install into the manually excavated pile, and also easy to lift and remove after construction.

[0029] like Figures 1-5 As shown, a lighting assembly 6 is also integrated below the shielding plate 1. The lighting assembly 6 includes a lighting support rod 61, a lighting support plate 62, and a lamp 63. One end of the lighting support rod 61 is obliquely fixed to the shielding plate 1, and the other end is connected to the lighting support plate 62. The lighting support plate 62 and the lighting support rod 61 can be connected by welding or threading to make them a whole. The lamp 63 adopts an LED industrial lamp, and a protrusion 631 is provided on the back of the lamp 63. The size of the protrusion 631 is slightly larger than the size of the back of the lamp 63. A slot 621 is provided on the lighting support plate 62. The cross-sectional shape of the slot 621 is the same as that of the protrusion 631. The lamp 63 is fixed by interlocking with the corresponding slot 621 on the lighting support plate 62 through the protrusion 631 on its back. When the protrusion 631 is fully embedded in the slot 621, a tight interference fit or mechanical interlock is formed between the two, so that the lamp 63 is firmly locked on the lighting support plate 62. It will not slip or loosen due to device movement or vibration caused by underground operation, ensuring continuous and stable lighting effect. The angle of the lamp 63 is adjustable, which can provide sufficient and shadow-free lighting for the working face at the bottom of the hole.

[0030] The inclined setting of the lighting support rod 61 makes the lighting assembly 6 tilt towards the working surface at the bottom of the hole, rather than pointing horizontally. This specific angle design ensures that the light can be concentrated and effectively cover the shoveling area under the worker's feet, while fundamentally avoiding strong light shining directly into the eyes of the worker in the center of the support 2, thus preventing discomfort and safety hazards caused by glare.

[0031] On both sides of the bracket 2, tie rods 7 are welded and fixed. The tie rods 7 extend inclinedly into the interior space of the bracket 2, and their ends are equipped with handles for easy gripping. Operators can use the tie rods 7 to actively fine-tune the position and orientation of the protective device at the bottom of the hole, ensuring that it is always in the optimal protective position.

[0032] The main structural components, such as bracket 2, guide rail 8, and shielding plate 1, are all made of lightweight, high-strength materials, such as aluminum alloy profiles, high-strength engineering plastics, or thin-walled alloy steel. Through optimized material selection, the overall weight is minimized while ensuring sufficient strength and rigidity of the structure, thereby ensuring that the device will not pose a safety hazard to the pile hole retaining wall when suspended or in operation.

[0033] The device is slidably connected to the ring guide rail 9 via the guide block 21. When the work area needs to be moved, the worker only needs to hold the pull rod 7 on the bracket 2 with one hand to apply traction force, which will drive the device to slide easily along the ring guide rail 9 to the new work point. At this time, the arc-shaped shield 1 moves accordingly and continues to provide continuous protection. The whole process does not require repeated lifting and lowering of the crane, which not only ensures zero interruption of rockfall protection, but also significantly improves work efficiency.

[0034] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
