Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an integrated device and construction method for deep foundation pit excavation and soil removal. Background Technology

[0002] In the construction of large-scale infrastructure projects such as building construction, subway stations, and underground utility tunnels, the application of deep foundation pit engineering is becoming increasingly common. Deep foundation pit excavation and removal are the core links in the foundation construction of building projects. Traditional excavation and removal equipment mostly relies on excavators repeatedly entering and leaving the foundation pit, and temporary construction trestle bridges are built to facilitate equipment passage.

[0003] However, the use of trestle bridges as excavator operating platforms also has obvious drawbacks: First, the erection and dismantling of the trestle bridge itself, as well as the back-and-forth movement of equipment on it, will occupy a lot of effective construction time. Moreover, in ultra-deep foundation pits, cumbersome layered excavation and multiple transfers are required, which is complicated and inefficient. Second, the dynamic load generated by the frequent operation of heavy equipment on the trestle bridge can easily cause adverse disturbances to the stability of the foundation pit slope. Therefore, this application proposes an integrated device and construction method for deep foundation pit excavation and soil removal. Summary of the Invention

[0004] The purpose of this invention is to address the problem of low construction efficiency of trestle bridges in the prior art by proposing an integrated device and construction method for deep foundation pit excavation and soil removal.

[0005] In a first aspect, the present invention provides an integrated device for deep foundation pit excavation and soil removal, including a chain bucket earthmoving hoist. Two sets of adjusting frames are installed on the outer side of the chain bucket earthmoving hoist. An earthmoving unloading hopper is provided at one end of the chain bucket earthmoving hoist. Two sets of support frames for supporting the earthmoving unloading hopper are fixedly connected to the bottom end of the earthmoving unloading hopper. Multiple sets of soil receiving frames are provided between the two sets of support frames. The device also includes:

[0006] The deceleration mechanism, connected to the earthwork unloading hopper, is used to buffer and decelerate the earthwork conveyed by the chain bucket earthmoving elevator.

[0007] A vibrating frame is fixed to the outside of a chain bucket earthmoving hoist. The vibrating frame has two sets of vibrating rods inside. One end of the vibrating rod is fixed to a horizontal plate. Two sets of guide rods slide through the inside of the horizontal plate. A spring is fixed between the horizontal plate and the inner wall of the vibrating frame.

[0008] The anti-caking mechanism is connected to the vibrating frame and is used to drive the vibrating rod, causing the vibrating rod to intermittently impact the inner wall of the vibrating frame to prevent soil from caking.

[0009] Optionally, the deceleration mechanism includes a buffer plate, a connecting rod, a conveyor belt, two sets of rotating shafts, and two sets of springs. The buffer plate is disposed inside the earthwork unloading hopper. The connecting rod is fixedly connected to the inner wall of the earthwork unloading hopper and is rotatably connected to the inside of the buffer plate. The conveyor belt rotates inside the buffer plate. Both sets of rotating shafts are rotatably connected to the inner wall of the buffer plate, and the conveyor belt is wound around the outside of the two sets of rotating shafts. Both sets of springs are fixedly connected between the inner wall of the earthwork unloading hopper and the buffer plate.

[0010] Optionally, the anti-caking mechanism includes a motor, a one-third gear, and a rack. The motor is mounted on the inner wall of the vibration frame, the one-third gear is connected to the output end of the motor, and the rack is fixed to the outside of the horizontal plate, with the one-third gear meshing with the rack.

[0011] Optionally, a screw is fixed to one end of the buffer plate near the second spring, a straight groove is opened on the outer side of the earthwork unloading hopper, the screw is located inside the straight groove, and a nut is threadedly connected to the outer side of the screw, and the nut fits against the outer side of the earthwork unloading hopper.

[0012] Optionally, the screw, straight groove and nut are provided in two sets, and the two sets of screw, straight groove and nut are symmetrically distributed.

[0013] Optionally, a connecting pipe and a supporting pipe are fixedly connected to the side of the two sets of horizontal plates near the vibrating rod, respectively. A clamping pipe is slidably connected to the outside of the supporting pipe, and the end of the clamping pipe away from the supporting pipe is slidably connected to the inside of the connecting pipe.

[0014] Optionally, the top end of the vibrating rod is provided with a threaded groove, and a vibrating cap is threadedly connected inside the threaded groove.

[0015] Optionally, a spur gear is fixedly connected to the outer side of the rotating shaft. The spur gear is located on the outer side of the earthwork unloading hopper. An arc-shaped rack is fixedly connected to the outer side of the earthwork unloading hopper. The spur gear meshes with the arc-shaped rack.

[0016] Optionally, a protective plate is provided on the outer side of the spur gear, and the protective plate is fixed to the outer side of the earthwork unloading hopper.

[0017] Secondly, the present invention provides an integrated construction method for deep foundation pit excavation and soil removal, applied to the integrated deep foundation pit excavation and soil removal device described in the first aspect. The method includes the following steps:

[0018] S1. Prepare the foundation pit working face and install and debug the equipment. Push the soil into the feed port of the chain bucket earthmoving machine using bulldozing equipment. The anti-caking mechanism prevents the soil from sticking together and ensures continuous feeding.

[0019] S2. Start the chain bucket earthmoving hoist to lift the earth from the bottom of the pit to the top and dump it into the earth unloading hopper. After the earth is slowed down and broken by the internal buffer plate, it falls into the uniformly moving earth receiving frame under the action of gravity.

[0020] S3. Fully loaded soil receiving frames are transported to the end of the conveyor belt, where they automatically tilt and unload into the soil storage area or transport vehicles. Empty frames return to receive materials, and the device is cleaned and moved after completion.

[0021] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0022] This invention effectively prevents soil accumulation and blockage by buffering and breaking up the falling soil through a deceleration mechanism. At the same time, the anti-caking mechanism drives the vibrating rod to intermittently transmit vibration force to the outside of the chain bucket earthmoving hoist. The resulting vibration prevents soil from clumping. The two work together to ensure the continuous and smooth operation of earthmoving during the lifting and unloading process.

[0023] Furthermore, by meshing the spur gear and the arc rack, the oscillation of the shaft is converted into the continuous rotation of the conveyor belt. This design not only effectively promotes the smooth falling of the soil through centrifugal force, but also significantly reduces the adhesion of soil to the surface of the conveyor belt due to the vibration generated, thereby improving unloading efficiency and cleanliness.

[0032] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0033] like Figure 1 and Figure 2 As shown, the present invention proposes an integrated deep foundation pit excavation and soil removal device, including a chain bucket earthmoving elevator 1. Two sets of adjusting frames 2 are installed on the outer side of the chain bucket earthmoving elevator 1. After the bottom working surface of the foundation pit is cleared, the chain bucket earthmoving elevator 1 is installed on the side of the foundation pit, and the adjusting frames 2 are used to adjust the chain bucket earthmoving elevator 1 to a suitable angle. Then, a small bulldozing device (a mature existing technology, not shown in this embodiment, and will not be elaborated upon) pushes the soil to the feeding port of the chain bucket earthmoving elevator 1. One end of the chain bucket earthmoving elevator 1 is equipped with a soil unloading hopper 3. The chain bucket earthmoving elevator 1 will... The excavated soil is lifted from the bottom to the top of the foundation pit and dumped into the soil unloading hopper 3 by gravity. The bottom of the soil unloading hopper 3 is fixed with two sets of support frames 4 for supporting the soil unloading hopper 3. The support frames 4 support the soil unloading hopper 3. Multiple sets of soil receiving frames 5 are set between the two sets of support frames 4. The soil falling into the soil unloading hopper 3 will eventually enter the soil receiving frames 5 under the action of gravity. The soil receiving frames 5 move at a constant speed with the external conveyor belt (the external conveyor belt is not shown in this embodiment and will not be described in detail). When it reaches the end, it automatically tilts and unloads the material to the soil pile area or external transport vehicles. The empty soil receiving frames 5 return to receive material again.

[0034] As one implementation method, such as Figure 1 , Figure 2 and Figure 3As shown, the deceleration mechanism in the integrated excavation and transportation device is connected to the earth unloading hopper 3. When the chain bucket earthmoving elevator 1 transports earth to the earth unloading hopper 3, the earth will hit the deceleration mechanism, which is used to buffer and decelerate the earth conveyed by the chain bucket earthmoving elevator 1. The deceleration mechanism also applies a reaction force to the earth, which can further disperse the earth and prevent the earth from piling up and falling naturally under the action of gravity.

[0035] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, the integrated excavation and removal device also includes a vibrating frame 6 fixed to the outside of the chain bucket earthmoving hoist 1. The vibrating frame 6 has two sets of vibrating rods 7 inside. In the initial state, the vibrating rods 7 are in contact with the inner wall of the vibrating frame 6. One end of each vibrating rod 7 is fixed to a horizontal plate 8. Two sets of guide rods 9 slide through the interior of the horizontal plate 8. The horizontal plate 8 moves stably along the outer side of the two sets of guide rods 9. A spring 10 is fixed between the horizontal plate 8 and the inner wall of the vibrating frame 6. The reaction force provided by the spring 10 can be transmitted to the vibrating rod 7 through the horizontal plate 8, causing the vibrating rod 7 to adhere to the inner wall of the vibrating frame 6. An anti-caking mechanism, connected to the vibrating frame 6, is used to drive the vibrating rod 7, causing the vibrating rod 7 to intermittently impact the vibration. The inner wall of the vibrating frame 6 prevents soil from caking. The anti-caking mechanism first moves the horizontal plate 8 away from the vibrating rod 7. When the horizontal plate 8 moves, it will cause the vibrating rod 7 to release its contact with the horizontal plate 8. When the horizontal plate 8 moves, it will also squeeze the spring 10, causing the spring 10 to deform under force and generate elastic potential energy. Subsequently, the anti-caking mechanism releases its control over the horizontal plate 8, and the spring 10 will release its elastic potential energy, pushing the horizontal plate 8 to reset. The reset of the horizontal plate 8 will cause the vibrating rod 7 to reset and impact the inner wall of the vibrating frame 6. The vibrating frame 6 is then impacted by the vibrating rod 7, thereby generating vibration force, which is transmitted to the chain bucket earthmoving elevator 1. At this time, the chain bucket earthmoving elevator 1 vibrates to prevent soil from caking.

[0036] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the deceleration mechanism includes a buffer plate 11, a connecting rod 12, a conveyor belt 13, two sets of rotating shafts 14, and two sets of springs 15. The deceleration mechanism is described in detail below:

[0037] The buffer plate 11 is installed inside the earthwork unloading hopper 3. When earthwork enters the earthwork unloading hopper 3, it will impact the buffer plate 11. The connecting rod 12 is fixed to the inner wall of the earthwork unloading hopper 3 and is rotatably connected to the inside of the buffer plate 11. When the buffer plate 11 is subjected to force, it will swing along the outside of the connecting rod 12. The conveyor belt 13 rotates inside the buffer plate 11. Both sets of rotating shafts 14 are rotatably connected to the inner wall of the buffer plate 11, and the conveyor belt 13 is wrapped around the outside of the two sets of rotating shafts 14. When the buffer plate 11 swings, it will also drive the conveyor belt 13 to swing through the rotating shafts 14. At this time, the buffer... When the plate 11 and the conveyor belt 13 swing, they slow down the descent speed of the soil and act as a buffer, preventing the soil from hitting the soil unloading hopper 3 for a long time and causing serious damage to the inner wall of the soil unloading hopper 3. Both sets of springs 15 are fixed between the inner wall of the soil unloading hopper 3 and the buffer plate 11. When the buffer plate 11 swings, it will also squeeze the springs 15, causing the springs 15 to deform under force and generate elastic potential energy. The reaction force applied by the springs 15 can also push the buffer plate 11 to reset. When the buffer plate 11 resets, it will hit the soil and break it up.

[0038] Among them, such as Figure 4 , Figure 5 and Figure 6 As shown, the anti-caking mechanism includes a motor 16, a one-third gear 17, and a spur rack 18. The anti-caking mechanism is described in detail below:

[0039] The motor 16 is mounted on the inner wall of the vibrating frame 6. The third gear 17 is connected to the output end of the motor 16. When the motor 16 is running, it drives the third gear 17 to rotate. The rack 18 is fixed to the outside of the horizontal plate 8, and the third gear 17 meshes with the rack 18. When the third gear 17 rotates, it drives the rack 18 to move. The movement of the rack 18 in turn drives the horizontal plate 8 to move. After the third gear 17 rotates a certain number of times, it releases its control over the rack 18. The spring 10 then releases its elastic potential energy, which pushes the vibrating rod 7 to strike the inner wall of the vibrating frame 6 through the horizontal plate 8. This causes the vibrating frame 6 to be subjected to force, driving the chain bucket earthmoving hoist 1 to vibrate, effectively preventing soil from clumping.

[0040] As one implementation method, such as Figure 2 and Figure 3As shown, a screw 19 is fixedly connected to one end of the buffer plate 11 near the second spring 15. When the buffer plate 11 swings, it will synchronously drive the screw 19 to swing. A straight groove 20 is opened on the outer side of the earthwork unloading hopper 3, and the opening of the straight groove 20 can provide space for the movement of the screw 19. The screw 19 is located inside the straight groove 20. A nut 21 is threadedly connected to the outer side of the screw 19, and the nut 21 fits against the outer side of the earthwork unloading hopper 3. The nut 21 is blocked by the outer side of the earthwork unloading hopper 3, thereby limiting the distance by which the second spring 15 pushes the buffer plate 11 to reset. When it is necessary to increase the reset distance of the buffer plate 11, the screw can be rotated. When nut 21 moves away from earthwork unloading hopper 3, buffer plate 11 can increase the swing distance until nut 21 contacts earthwork unloading hopper 3. The greater the angle of swing of buffer plate 11 away from screw 19, the shorter the contact distance between buffer plate 11 and earthwork, and the greater the buffering effect of buffer plate 11 on earthwork. Screw 19, straight groove 20 and nut 21 are provided in two sets, and the two sets of screw 19, straight groove 20 and nut 21 are symmetrically distributed. The two sets of screw 19, straight groove 20 and nut 21 can be used in place of one set if one set is damaged.

[0041] Furthermore, such as Figure 5 and Figure 6 As shown, a connecting pipe 22 and a supporting pipe 23 are respectively fixed to the side of the two sets of horizontal plates 8 near the vibrating rod 7. A clamping pipe 24 is slidably connected to the outside of the supporting pipe 23. The clamping pipe 24 can move laterally along the outside of the supporting pipe 23. The end of the clamping pipe 24 away from the supporting pipe 23 is slidably connected to the inside of the connecting pipe 22. When one end of the clamping pipe 24 is inserted into the inside of the connecting pipe 22, when one set of horizontal plates 8 moves, the horizontal plate 8 can drive the clamping pipe 24 to move vertically through the supporting pipe 23. The movement of the clamping pipe 24 can drive the other set of horizontal plates 8 to move vertically through the connecting pipe 22. This achieves synchronous movement of the two sets of horizontal plates 8, saves one drive source, reduces production costs, and when it is necessary to reduce the vibration force, the clamping pipe 24 can be moved out of the inside of the connecting pipe 22 to achieve movement of one set of horizontal plates 8. It should be noted that the friction between the clamping pipe 24 and the connecting pipe 22 is relatively large. Therefore, the clamping pipe 24 will not detach from the inside of the connecting pipe 22 when moving.

[0042] Furthermore, such as Figure 5 and Figure 6 As shown, the top end of the vibrating rod 7 is provided with a threaded groove 25, and the internal thread of the threaded groove 25 is connected to a vibrating cap 26. When the vibrating rod 7 impacts the vibrating frame 6, the vibrating cap 26 will contact the vibrating frame 6 first. The threaded connection between the vibrating cap 26 and the threaded groove 25 makes it easy to disassemble and assemble the vibrating cap 26, thus providing convenience for the maintenance of the vibrating cap 26.

[0043] Among them, such as Figure 7 As shown, a spur gear 27 is fixedly connected to the outer side of the rotating shaft 14. When the rotating shaft 14 swings, it will drive the spur gear 27 to swing synchronously. The spur gear 27 is located on the outer side of the earthwork unloading hopper 3. An arc-shaped rack 28 is fixedly connected to the outer side of the earthwork unloading hopper 3. The spur gear 27 meshes with the arc-shaped rack 28. When the spur gear 27 swings, it will rotate along the inner side of the arc-shaped rack 28. The rotation of the spur gear 27 will drive the conveyor belt 13 to rotate through the rotating shaft 14. When the conveyor belt 13 rotates, it will apply centrifugal force to the soil on its surface, which will facilitate the falling of the soil. In addition, the vibration force generated by the transmission of the conveyor belt 13 can also effectively prevent the soil from adhering.

[0044] In addition, such as Figure 7 As shown, a protective plate 29 is provided on the outer side of the spur gear 27. The protective plate 29 is fixed to the outer side of the earthwork unloading hopper 3. The protective plate 29 can shield and protect the spur gear 27 and the arc-shaped rack 28.

[0045] A method for integrated excavation and soil removal in deep foundation pits, comprising the following steps:

[0046] S1. Prepare the foundation pit working face and install and debug the device. Push the soil into the feed port of the chain bucket earthmoving machine 1 using bulldozing equipment. The anti-caking mechanism prevents the soil from sticking and ensures continuous feeding.

[0047] S2. Start the chain bucket earthmoving hoist 1 to lift the earth from the bottom of the pit to the top and dump it into the earthmoving unloading hopper 3. After the earthmoving is slowed down and broken up by the internal buffer plate 11, it falls into the uniformly moving earth receiving frame 5 under the action of gravity.

[0048] S3. The fully loaded soil receiving frame 5 is transported to the end of the conveyor belt, automatically tilted to unload the material into the soil storage area or transport vehicle, and the empty frame returns to receive material. After completion, the device is cleaned and moved.

[0049] In this embodiment, after the bottom of the foundation pit is cleared, the chain bucket earthmoving elevator 1 is installed on the side of the foundation pit. The chain bucket earthmoving elevator 1 is adjusted to a suitable angle using the adjusting frame 2. Then, a small bulldozer pushes the earth to the feeding point of the chain bucket earthmoving elevator 1. The chain bucket earthmoving elevator 1 lifts the earth from the bottom of the foundation pit to the top, and then, through gravity, dumps it into the earth unloading hopper 3. The earth falling into the earth unloading hopper 3, under the influence of gravity, eventually enters the receiving frame 5. The receiving frame 5 moves at a constant speed with the external conveyor belt, and at the end, it automatically tilts to unload the earth into the stockpile area or onto external transport vehicles. The empty receiving frame 5 returns to receive earth repeatedly. The chain bucket earthmoving elevator 1 transfers earth to the earth unloading hopper 3. When the soil is inside, it will impact the buffer plate 11. The buffer plate 11 will swing along the outside of the connecting rod 12 under the force. When the buffer plate 11 swings, it will also drive the conveyor belt 13 to swing through the rotating shaft 14. At this time, the swinging of the buffer plate 11 and the conveyor belt 13 will slow down the descent speed of the soil and play a buffering role, avoiding the soil from hitting the soil unloading hopper 3 for a long time, which would cause serious damage to the inner wall of the soil unloading hopper 3. When the buffer plate 11 swings, it will also squeeze the second spring 15, causing the second spring 15 to deform under the force and generate elastic potential energy. The reaction force applied by the second spring 15 can also push the buffer plate 11 to reset. When the buffer plate 11 resets, it will impact the soil and break it up.

[0050] In the initial state, the vibrating rod 7 is in contact with the inner wall of the vibrating frame 6. When the motor 16 is running, it drives the one-third gear 17 to rotate. When the one-third gear 17 rotates, it drives the rack 18 to move. The movement of the rack 18 in turn drives the horizontal plate 8 to move. When the horizontal plate 8 moves, it causes the vibrating rod 7 to release its contact with the horizontal plate 8. When the horizontal plate 8 moves, it also compresses the spring 10, causing the spring 10 to deform under force and generate elastic potential energy. After the one-third gear 17 rotates a certain number of times, the one-third gear 17 will release its control over the rack 18. The spring 10 will then release its elastic potential energy, which will push the vibrating rod 7 to hit the inner wall of the vibrating frame 6 through the horizontal plate 8. This causes the vibrating frame 6 to be subjected to force and drive the chain bucket earthmoving hoist 1 to vibrate, effectively preventing soil from clumping.

[0051] When one end of the clamping tube 24 is inserted into the interior of the connecting tube 22, when a set of horizontal plates 8 moves, the horizontal plates 8 can drive the clamping tube 24 to move vertically through the support tube 23. The movement of the clamping tube 24 can drive the other set of horizontal plates 8 to move vertically through the connecting tube 22, thereby achieving synchronous movement of the two sets of horizontal plates 8. Furthermore, when it is necessary to reduce the vibration force, the clamping tube 24 can be moved out of the interior of the connecting tube 22, thereby achieving the movement of a set of horizontal plates 8.

[0052] When the rotating shaft 14 swings, it drives the spur gear 27 to swing synchronously. When the spur gear 27 swings, it rotates along the inner side of the arc-shaped rack 28. The rotation of the spur gear 27 drives the conveyor belt 13 to rotate through the rotating shaft 14. When the conveyor belt 13 rotates, it applies centrifugal force to the soil on its surface, which facilitates the falling of the soil. In addition, the vibration force generated by the transmission of the conveyor belt 13 can also effectively prevent the soil from adhering.

[0053] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
