Description

Technical Field

[0001] This utility model belongs to the field of manual excavation pile construction technology, specifically relating to a safe slag removal device for pile foundation construction. Background Technology

[0002] Pile foundation construction is an indispensable part of the construction industry, playing a crucial role in ensuring the stability and safety of buildings. With the advancement of technology and the continuous improvement of engineering requirements, pile foundation construction technology will continue to innovate and improve. Under current technological conditions, pile foundation construction mainly relies on two methods: machinery and manual labor. Mechanical construction mainly relies on various advanced pile driving equipment to efficiently and accurately complete pile foundation construction. However, in complex terrain or pile foundation locations where pile driving machines cannot reach the required hole diameter, the machines cannot operate normally. In such cases, manual construction becomes particularly important. Manual excavation has the characteristics of flexibility and adaptability, and can cope with various complex terrains and special situations.

[0003] In the construction of manually excavated bored piles, safety protection inside the construction hole is crucial, directly affecting the lives of construction workers. Workers are excavating at the bottom of the pile foundation when debris may fall from above, affecting operations and even endangering their lives. Therefore, current technology typically involves erecting a semi-circular protective plate atop the inverted frustum-shaped concrete retaining wall of the pile foundation. This plate, positioned above the workers' heads, acts as a buffer against falling objects. However, this semi-circular protective plate still has some drawbacks in manually excavated bored pile construction: 1. The protective plate, erected directly on top of the concrete retaining wall, is easily loosened and displaced by external disturbances, potentially falling and posing a safety hazard; 2. During excavation, the position of the protective plate needs to be adjusted according to the workers' direction of excavation. Because the pile foundation hole is deep and the protective plate is heavy, adjusting its position requires both crane and manual labor, which is time-consuming and labor-intensive. Furthermore, the protective plate may get stuck in the concrete retaining wall during movement, making construction inconvenient and reducing safety. Summary of the Invention

[0004] The purpose of this utility model is to provide a safe slag removal device for pile foundation construction, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A safety slag discharge device for pile foundation construction includes a protective plate with an adjustable diameter, a through hole in the middle of the protective plate for a slag bucket to pass through, multiple adjustable legs evenly arranged around the center of the protective plate at the bottom of the protective plate, an adjustment component between the protective plate and the legs for adjusting the diameter of the protective plate, a baffle hinged to the protective plate for blocking the through hole, and a switch component between the baffle and the legs for opening or closing the baffle.

[0007] Preferably, the protective plate includes: a circular center plate, a plurality of T-shaped grooves evenly arranged radially around the center of the center plate on the bottom surface of the center plate, a T-shaped slider slidably disposed in the T-shaped grooves, and a plurality of fan-shaped plates respectively connected to the T-shaped sliders. The number of T-shaped grooves and fan-shaped plates is the same as the number of support legs. The support legs are disposed on the center plate, and the through holes are disposed through the center plate.

[0008] Preferably, the support leg includes: a fixed rod whose top end is fixedly connected to the bottom surface of the center plate, has an open bottom end and is hollow inside; a bottom rod whose top end is slidably disposed on the inner and outer walls of the fixed rod and has threads; and a connecting cylinder that is hollow inside, has one end rotatably sleeved on the bottom of the fixed rod and the other end threaded on the bottom rod.

[0009] Preferably, the outer wall of the fixed rod is provided with threads, and the adjusting assembly includes: an adjusting cylinder threaded on the fixed rod, an mounting cylinder rotatably sleeved on the upper part of the adjusting cylinder, and an adjusting rod with one end hinged to the bottom surface of the sector plate and the other end hinged to the mounting cylinder.

[0010] Preferably, an anti-slip rubber sleeve is fixedly fitted on the lower outer wall of the adjusting cylinder.

[0011] Preferably, the switch assembly includes: a fixed seat fixedly sleeved on a fixed rod near the hinged end of the baffle; a support rod with its top end hinged to the bottom surface of the baffle; a fixed hole through the bottom end of the support rod; a U-shaped mounting seat with its bottom surface fixedly connected to the fixed seat; mounting holes through the side walls on both sides of the U-shaped mounting seat; and bolts through the two mounting holes.

[0012] Preferably, one end of the bottom surface of the baffle is movably hinged to the protective plate via a hinge, and the baffle is a mesh plate.

[0013] Preferably, any of the fan-shaped plates has a notch on its edge and on the protective plate.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. This utility model allows the protective plate to be installed and supported by adjusting its diameter, with its edge resting on the top of the concrete retaining wall. Adjustable legs at the bottom of the protective plate further enhance its support, ensuring stability and load-bearing capacity. A switch assembly controls the opening and closing of the baffle at the through-hole, allowing workers to quickly open the baffle when slag removal is needed and close it afterward. This ensures both construction continuity and worker safety. The protective plate and baffle completely cover the pile hole, significantly reducing labor intensity, improving construction efficiency, effectively preventing debris from falling to the bottom, protecting workers' lives, and further enhancing the safety of the operation.

[0016] 2. By rotating the connecting cylinder, the length of the bottom rod extending out of the fixed rod can be adjusted, thereby adjusting the length of the outrigger. Construction personnel can adjust the length of the outrigger at any time according to the depth of the excavation. The depth of the protective plate can also be adjusted by adjusting the length of the outrigger, which improves the flexibility and ease of use of the device.

[0017] 3. This utility model allows the adjusting cylinder and the mounting cylinder to move on the fixed rod by rotating the adjusting cylinder. Then, the adjusting rod can be used to apply force to the sector plate, causing the sector plate to slide at the bottom of the central plate, thereby realizing the extension and retraction adjustment of the sector plate and changing the diameter of the protective plate. This ensures that the device can be flexibly installed or disassembled in the pile foundation hole, improving construction efficiency and enabling the device to be reused.

[0018] 4. This utility model can control the rapid opening and closing of the baffle by swinging the support rod. By setting a fixed seat on the fixed rod and a U-shaped mounting seat on the fixed seat, the bolt can pass through the mounting hole and be fixed to the support rod located in the U-shaped mounting seat, so as to realize the fixing and adjustment of the support rod.

[0019] 5. This utility model uses a grid plate design for the baffle, which can not only ensure a certain protective function, but also reduce the weight of the baffle and ensure the ventilation of the head inside the hole, which is conducive to observing the situation inside the through hole and improving the safety during construction. By providing notches on the edge of any of the fan-shaped plates and the protective plate, it is convenient for the passage of rope ladders and water and electricity pipes.

Obviously, the described embodiments are only a part of the 14 embodiments of this utility model, not all of them.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] like Figure 1-4 As shown, a safety slag discharge device for pile foundation construction includes a protective plate 1 with an adjustable diameter, a through hole 2 through the middle of the protective plate 1 for the slag bucket to pass through, multiple adjustable legs 3 evenly arranged around the center of the protective plate 1 at the bottom of the protective plate 1, an adjustment component 4 disposed between the protective plate 1 and the legs 3 for adjusting the diameter of the protective plate 1, a baffle 5 hinged to the protective plate 1 for blocking the through hole 2, and a switch component 6 disposed between the baffle 5 and the legs 3 for opening or closing the baffle 5.

[0035] In practice, this device can adjust the diameter of the protective plate 1 according to the size of the pile hole by adjusting component 4, so that it matches the pile hole. This allows the edge of the protective plate 1 to be placed on top of the concrete retaining wall for installation support. Then, by setting adjustable-length support legs 3 at the bottom of the protective plate 1, the support legs 3 can firmly support the bottom of the pile hole, further providing stable support for the protective plate 1 and ensuring the stability and load-bearing capacity of the device. When it is necessary to discharge the excavated soil or stone debris, the baffle 5 is opened by the switch component 6 to expose the through hole 2. Then, the slag bucket is inserted into the pile hole through the through hole 2 to collect the soil or stone debris and then pull it out. After the slag discharge is completed, the baffle 5 is closed by the switch component 6 to prevent debris or soil from falling back into the pile hole. This ensures both the continuity of construction and the safety of construction personnel. The protective plate 1 and the baffle 5 can completely cover the pile hole, greatly saving labor intensity, improving construction efficiency, effectively preventing debris from falling to the bottom, ensuring the safety of personnel working in the hole, and further improving the safety of the operation process.

[0036] like Figures 2-4 As shown, the protective plate 1 includes: a circular central plate 7, a plurality of T-shaped grooves 8 evenly arranged radially around the center of the central plate 7 on the bottom surface of the central plate 7, a T-shaped slider 9 slidably disposed in the T-shaped grooves 8, and a plurality of fan-shaped plates 10 respectively connected to the T-shaped slider 9. The number of T-shaped grooves 8 and fan-shaped plates 10 is the same as the number of support legs 3. The support legs 3 are disposed on the central plate 7, and the through hole 2 is disposed through the central plate 7.

[0037] The support leg 3 includes: a fixed rod 11 with its top end fixedly connected to the bottom surface of the center plate 7, an open bottom end and a hollow interior; a bottom rod 12 with its top slidably disposed inside the fixed rod 11 and threaded on its outer side wall; and a connecting cylinder 13 with its interior hollow, one end rotatably sleeved on the bottom of the fixed rod 11 and the other end threaded on the bottom rod 12.

[0038] The fixing rod 11 has a threaded outer wall, and the adjusting assembly 4 includes: an adjusting cylinder 14 threaded onto the fixing rod 11, a mounting cylinder 15 rotatably sleeved on the upper part of the adjusting cylinder 14, and an adjusting rod 16 with one end hinged to the bottom surface of the sector plate 10 and the other end hinged to the mounting cylinder 15.

[0039] Multiple T-shaped grooves 8 and corresponding T-shaped sliders 9 are set on the central plate 7, and a sector plate 10 connected to the T-shaped slider 9 can be easily adjusted to change the position of the sector plate 10, thereby allowing the diameter of the protective plate 1 to be flexibly adjusted. The T-shaped slider slides in the T-shaped groove, and the sector plate 10 can move outward or inward, thereby changing the overall diameter of the protective plate 1. This allows the device to flexibly change the shape and size of the protective plate 1 according to actual needs, adapting to pile foundation construction with different hole diameters. The specific principle of adjusting the diameter of the protective plate 1 through the adjusting component 4 is as follows: rotating the adjusting cylinder 14 allows the adjusting cylinder 14 and the mounting cylinder 15 to move on the fixed rod 11. Since one end of the adjusting rod 16 is hinged to the bottom surface of the sector plate 10 and the other end is hinged to the mounting cylinder 15, the up and down movement of the mounting cylinder 15 will drive the adjusting rod 16, thereby pushing the sector plate 10 to slide in the T-shaped groove, realizing the adjustment of the diameter of the protective plate 1, thereby changing the diameter of the protective plate 1, ensuring that the device can be flexibly installed or disassembled in the pile foundation hole, improving construction efficiency, and realizing the reuse of the device.

[0040] When it is necessary to adjust the length of the outrigger 3, the connecting cylinder 13 can be rotated to adjust the length of the bottom rod 12 extending out of the fixed rod 11, thereby adjusting the length of the outrigger 3. Construction personnel can adjust the length of the outrigger 3 at any time according to the depth of the excavation. The depth of the protective plate 1 can also be adjusted by adjusting the length of the outrigger 3, which improves the flexibility and ease of use of the device.

[0041] To facilitate the operator's application of force and prevent hand slippage, thereby improving the accuracy and efficiency of adjustment, an anti-slip rubber sleeve is fixedly fitted on the lower outer wall of the adjustment cylinder 14 to increase the friction between the hand and the adjustment cylinder 14.

[0042] like Figures 2-4 As shown, the switch assembly 6 includes: a fixed seat 18 fixedly sleeved on a fixed rod 11 near the hinge end of the baffle 5; a support rod 19 whose top end is hinged to the bottom surface of the baffle 5; a fixed hole 20 passing through the bottom end of the support rod 19; a U-shaped mounting seat 21 whose bottom surface is fixedly connected to the fixed seat 18; mounting holes 22 passing through the side walls on both sides of the U-shaped mounting seat 21; and bolts 23 passing through the two mounting holes 22.

[0043] When it is necessary to open the baffle 5 for slag discharge, first pull out the bolt 23 from the mounting holes 22 on both sides of the U-shaped mounting base and the fixing holes 20 at the bottom of the support rod 19. After pulling out the bolt 23, the support rod 19 no longer supports the baffle 5, causing the baffle 5 to rotate downwards around the hinge under its own weight, exposing the through hole 2. At this time, the slag discharge bucket can transport the slag through the through hole 2. When the slag discharge operation is completed and it is necessary to close the baffle 5 to restore the protective state, push the baffle 5 upwards through the support rod 19 to make it rotate back around the hinge. The original position is covered by the through hole 2 on the protective plate 1. Then, the fixing hole 20 at the bottom of the support rod 19 is aligned with the mounting holes 22 on both sides of the U-shaped mounting base. Then, the bolt 23 is inserted so that the support rod 19 restores its supporting function for the baffle 5 and prevents debris from falling into the bottom of the pile hole from the through hole 2 during construction, ensuring the safety of the workers. In practice, in order to improve the fixing effect of the bolt 23 and prevent the bolt 23 from accidentally falling out of the hole and causing the support rod 19 to lose its supporting function, the end of the bolt 23 can be threaded with a nut.

[0044] One end of the bottom surface of the baffle 5 is movably hinged to the protective plate 1 via a hinge. The baffle 5 is a grid plate. The grid plate design can not only ensure a certain protective function, but also reduce the weight of the baffle 5, ensure the air permeability of the head inside the hole, facilitate the observation of the situation inside the through hole 2, and improve the safety during the construction process.

[0045] To facilitate the passage of rope ladders and water and electricity pipes, a notch 24 is provided on the edge of any of the fan-shaped plates 10 and on the protective plate 1.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made without departing from the spirit and scope of this utility model as defined in the appended claims.
