Description

Technical Field

[0001] This utility model relates to the field of protection technology for impact drill pile formation, and in particular to an anti-collapse hole device for impact drill pile formation. Background Technology

[0002] In the current construction of impact drilling for building pile foundations, bridge foundations and other projects, the risk of pile hole collapse in loose sand layers, water-rich strata or backfilled soil layers has always been the core pain point restricting construction efficiency and quality. Therefore, there is a need for an anti-collapse hole device for impact drilling pile body to solve this problem.

[0003] In the existing technology, the existing anti-collapse hole equipment for impact drilling pile forming mostly has an internal support frame with a fixed diameter, which cannot be adapted to pile holes of different diameters. Moreover, when the entire anti-collapse device is placed into the hole, its anti-collapse plate will cause great friction with the inner wall of the hole, which can easily lead to damage to the anti-collapse plate or collapse inside the hole. It has great limitations and poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where the internal support frame is mostly of a fixed diameter, which cannot be adapted to pile holes of different diameters, and when the entire anti-collapse device is placed into the hole, its anti-collapse plate will cause great friction with the inner wall of the hole, which can easily lead to damage to the anti-collapse plate or collapse inside the hole. Therefore, an anti-collapse hole device for impact drilling pile body is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-collapse hole device for impact drilling pile forming, comprising a housing, anti-collapse plates on both sides of the housing, a sleeve fixed to the top of the housing, a connecting column fixed to the bottom of the housing, a driving structure for driving the two anti-collapse plates to move in opposite directions within the housing, an inner cavity opened at one end of each anti-collapse plate, a telescopic component installed on the inner wall of the inner cavity, and a guide wheel provided at the output end of the telescopic component.

[0006] Preferably, the driving structure includes a driving source installed inside the housing. A bidirectional screw is fixed to the output end of the driving source. Both ends of the outer wall of the bidirectional screw are threadedly connected to movable plates. The ends of the two movable plates away from the bidirectional screw are slidably connected to limit posts. The opposite ends of the two movable plates are fixed to connecting frames. The opposite ends of the two connecting frames pass through the housing and are respectively fixed to two anti-collapse plates. By operating the driving source, the bidirectional screw is driven to rotate, causing the two movable plates to move towards or in opposite directions under the limit of the limit posts. This enables the two anti-collapse plates connected to the two connecting frames to move towards or in opposite directions, allowing the position of the two anti-collapse plates to be adjusted according to the diameter of the hole, adapting to holes of different widths and improving practicality.

[0007] Preferably, the top end of the sleeve has a slot that matches the connecting post. The connecting post is fixed to the sleeve by bolts. The combination of the connecting post, bolts, and sleeve allows the housing to be connected to other housings, making it easy to directly install the corresponding housing according to the actual hole length. This allows the overall height of the device to be adjusted, and when a component of one housing is damaged, only that component needs to be replaced, without replacing the entire housing, making it more practical.

[0008] Preferably, the outer wall of the connecting column is provided with a plurality of limiting holes that match the bolts. By setting the limiting holes, when the bolt threads are inserted into different limiting holes, the depth of the connecting column in the sleeve can be adjusted, thereby adjusting the distance between the two housings.

[0009] Preferably, the end of the bidirectional screw away from the drive source is rotatably connected to the housing, both ends of the limiting post are fixed to the housing, and both ends of the housing are provided with connecting slots that match the connecting frame. By rotatably connecting the end of the bidirectional screw away from the drive source to the housing, both ends of the bidirectional screw have a point of force, making its operation more stable.

[0010] Preferably, the output end of the telescopic component is fixed with a support plate, and the guide wheel is installed at the end of the support plate away from the telescopic component. By setting the support plate, the force-bearing area can be expanded and the stress can be dispersed. If there is no support plate, the output end of the telescopic component is directly connected to the guide wheel, which will cause local stress concentration due to the small contact area, resulting in deformation and damage to the end of the telescopic component or the guide wheel shaft seat, thus making the stability stronger.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the operation of the drive source drives the bidirectional screw to rotate, causing the two moving plates to move towards or away from each other under the limitation of the limiting post. This enables the two anti-collapse plates connected by the two connecting frames to move towards or away from each other, allowing the position of the two anti-collapse plates to be adjusted according to the diameter of the hole, adapting to holes of different widths and enhancing practicality. When placing the entire device into the hole, the operation of the telescopic component drives the support plate and guide wheel to move, causing the guide wheel to move out of the inner cavity opened at one end of the anti-collapse plate. At this time, when the entire device is placed into the hole, the guide wheel will contact the inner wall of the hole. Its rotational characteristics indirectly guide the placement of the entire device. Also, because its contact area with the inner wall of the hole is small, friction is reduced, avoiding the phenomenon of collapse of the inner wall of the hole due to mud, etc., thus enhancing stability.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figures 1-4This utility model provides a technical solution: an anti-collapse hole device for impact drilling pile forming, including a housing 1, with anti-collapse plates 2 on both sides of the housing 1, a sleeve 9 fixed to the top of the housing 1, and a connecting column 10 fixed to the bottom of the housing 1. The housing 1 contains a drive structure 3 for driving the two anti-collapse plates 2 to move in opposite directions. One end of each anti-collapse plate 2 has an inner cavity 5, and a telescopic component 6 is installed on the inner wall of the inner cavity 5. The output end of the telescopic component 6 is equipped with a guide wheel 8. Through the operation of the drive structure 3, the two anti-collapse plates 2 can be driven to move in opposite directions, thereby supporting the inner wall of the hole formed by the two anti-collapse plates 2 to achieve the anti-collapse effect. Through the operation of the telescopic component 6, the support plate 7 and the guide wheel 8 are driven to move, causing the guide wheel 8 to move out of the inner cavity 5 at one end of the anti-collapse plate 2. In cavity 5, when the entire device is placed into the hole, the guide wheel 8 will contact the inner wall of the hole. Its rotational characteristics indirectly guide the placement of the entire device. Because its contact area with the inner wall of the hole is small, friction is reduced, preventing the collapse of the inner wall due to soil, thus increasing stability. In this application, each connecting box 1 is staggered with the previous box 1. This application also includes an external power supply and controller for powering and controlling the drive source 301 and the telescopic component 6. Therefore, they will not be described in detail here. In this application, the drive source 301 and the telescopic component 6 can be a motor, an electric telescopic rod, an electric push rod, etc. They only need to drive the bidirectional screw 302 to rotate and the support plate 7 to move; there are no special limitations. Figure 3 and Figure 4 The drive source 301 and the telescopic component 6 used inside are a motor and an electric telescopic rod, respectively.

[0021] like Figures 1-4 As shown, the drive structure 3 includes a drive source 301 installed inside the housing 1. A bidirectional screw 302 is fixed to the output end of the drive source 301. Both ends of the outer wall of the bidirectional screw 302 are threadedly connected to movable plates 303. The ends of the two movable plates 303 away from the bidirectional screw 302 are slidably connected to a limit post 304. A connecting frame 305 is fixed to the opposite ends of the two movable plates 303. The opposite ends of the two connecting frames 305 pass through the housing 1 and are respectively fixed to the two anti-collapse plates 2. By running the drive source 301, the bidirectional screw 302 is driven to rotate, causing the two movable plates 303 to move towards or away from each other under the limit of the limit post 304. This allows the two anti-collapse plates 2 connected by the two connecting frames 305 to move towards or away from each other, so that the position of the two anti-collapse plates 2 can be adjusted according to the diameter of the hole, adapting to holes of different widths and making it more practical.

[0022] like Figures 1-4As shown, the top of the sleeve 9 has a slot that matches the connecting post 10. The connecting post 10 is fixed to the sleeve 9 by bolts 11. With the connection post 10, bolts 11 and sleeve 9, the housing 1 can be connected to install other housings 1, which makes it easy to directly install the corresponding housing 1 according to the actual hole length. On the one hand, the overall height of the device can be adjusted. On the other hand, when a component of one of the housings 1 is damaged, only that component needs to be replaced, without replacing the whole device, which makes it more practical.

[0023] like Figures 1-4 As shown, the outer wall of the connecting post 10 is provided with a plurality of limiting holes 12 that match the bolts 11. By setting the limiting holes 12, when the bolts 11 are threaded into different limiting holes 12, the depth of the connecting post 10 in the sleeve 9 can be adjusted, thereby adjusting the distance between the two housings 1.

[0024] like Figures 1-4 As shown, the end of the bidirectional screw 302 away from the drive source 301 is rotatably connected to the housing 1. Both ends of the limiting post 304 are fixed to the housing 1. Both ends of the housing 1 are provided with connecting slots 4 that match the connecting frame 305. By rotatably connecting the end of the bidirectional screw 302 away from the drive source 301 to the housing 1, both ends of the bidirectional screw 302 have a force point, making its operation more stable.

[0025] like Figures 1-4 As shown, the output end of the telescopic component 6 is fixed with a support plate 7, and the guide wheel 8 is installed at the end of the support plate 7 away from the telescopic component 6. By setting the support plate 7, it can expand the force-bearing area and disperse the stress. If there is no support plate 7, the output end of the telescopic component 6 is directly connected to the guide wheel 8, which will cause local stress concentration due to the small contact area, resulting in deformation and damage to the end of the telescopic component 6 or the shaft seat of the guide wheel 8. The stability is stronger.

[0026] The device's operation and working principle are as follows: When in use, the drive source 301 drives the bidirectional screw 302 to rotate, causing the two moving plates 303 to move towards or away from each other under the limiting position of the limiting post 304. This, in turn, drives the two anti-collapse plates 2 connected by the two connecting frames 305 to move towards or away from each other, allowing the position of the two anti-collapse plates 2 to be adjusted according to the diameter of the hole, adapting to holes of different widths and enhancing practicality. When placing the entire device into the hole, the telescopic component 6 drives the support plate 7 and guide wheel 8 to move, causing the guide wheel 8 to move out of the inner cavity 5 opened at one end of the anti-collapse plate 2. At this point, when placing the entire device into the hole, the guide wheel 8 will contact the inner wall of the hole. Its rotational characteristics indirectly guide the placement of the entire device. Furthermore, because its contact area with the inner wall of the hole is small, friction is reduced, preventing the inner wall of the hole from collapsing due to soil, thus enhancing stability.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
