Description

Technical Field

[0001] This invention belongs to the field of vertical tunneling machine technology, specifically a vertical tunneling machine advanced support bracket. Background Technology

[0002] Vertical tunneling machines are a common type of excavation equipment in modern society, often used for shaft excavation. They have a wide range of applications and can be used in land, river, and marine environments.

[0003] Currently, in existing technologies, vertical tunneling machines often rely on bottom excavation equipment to break up and extract soil. During the excavation process, the cylindrical channel excavated by the vertical tunneling machine needs to be supported and maintained around the surrounding soil to reduce the occurrence of collapse. At the same time, when carrying out large-scale vertical shaft excavation, multiple vertical tunneling machines need to be used to excavate in a unified manner and then connected to complete the construction of large vertical shafts.

[0004] After the existing shaft is excavated, it is often necessary to extract the water source inside the shaft that maintains the soil pressure. At this time, during the movement of the water flow, the quicksand at the bottom of the shaft will move along with it, causing the mud and sand at the bottom and side walls of the shaft to shift, creating voids, affecting the soil pressure balance, and causing the soil layer in the shaft to collapse, affecting the progress of the project. Therefore, a vertical tunneling machine advance support bracket is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A vertical tunneling machine advance support frame, comprising a support frame; the support frames are arranged in pairs; multiple sets of connecting rods are fixedly connected between the pair of support frames; multiple sets of support rods are provided inside the support frame; a positioning block is provided at the top of the support frame; multiple sets of filter screens are provided on the side wall of the positioning block; a main support plate is fixedly connected to the middle of each set of filter screens; side support plates are fixedly connected to both side walls of each set of filter screens; the gap between the multiple sets of side support plates is larger than the diameter of the support rods; telescopic barriers are installed between each set of connecting rods; during operation, this step utilizes the support frames and connecting rods... The telescopic fence provides support around the bottom of the shaft, maintaining pressure on the soil around the perimeter during water extraction and reducing the risk of collapse. Simultaneously, movable positioning blocks can enter the support frame and, through the filtering effect of the filter screen, compress impurities at the bottom of the shaft, causing debris to accumulate at the bottom of the support frame. This reduces the movement of silt and sand at the bottom of the shaft with the pumping equipment during water extraction, preventing voids and soil collapse. The filter screen also acts as a filter during pumping, reducing debris entering the pumping pipes and preventing blockages that could affect pumping efficiency.

[0007] Preferably, the main support plate and the positioning block are rotatably connected by a first rotating shaft; the two side walls of the main support plate are hinged to a second rotating shaft by torsion springs; the end of the side support plate is connected to the side wall of the second rotating shaft; a first connecting rope is wound around both the second and first rotating shafts; a connecting column is rotatably connected to the top of the positioning block; multiple sets of main support plates are fixedly connected to the top of the second connecting rope; the other end of the second connecting rope is wound around the side wall of the connecting column. During operation, this step utilizes the rotatable effect of the connecting column to unfold the filter screen and suppress impurities in the water when drainage is required. At the same time, when drainage is not required, the rotation of the first rotating shaft can cause the main support plate to retract and move closer to the connecting column, thereby reducing the space occupied by the filter screen in the flattened state and improving space utilization.

[0008] Preferably, a positioning post is fixedly connected to the middle of the support rod; a first sliding groove is opened at the top of the positioning post; multiple sets of second sliding grooves are opened on the side wall of the first sliding groove; the second sliding groove 32 is located between each pair of support rods 12; the diameter of the main support plate is smaller than the diameter of the second sliding groove; during operation, this step, by installing the positioning post, can keep the positioning block in the center position of the support bracket during the falling process, reduce the collision between the filter screen and the side wall of the support bracket that causes displacement, and increase the stability of the filter screen when in contact with debris.

[0009] Preferably, a third slide is provided at the top of the first slide; multiple sets of third rotating shafts are hinged to the top of the third slide via torsion springs; guide plates are fixed to the side walls of the third rotating shafts; the multiple sets of guide plates are inclined toward the center of the positioning column; during operation, this step utilizes the guiding effect of the guide plates to assist the positioning block in entering the first slide when it falls, reducing the occurrence of jamming between the positioning block and the bottom of the positioning column, which would affect the normal falling of the positioning block and thus affect the work progress.

[0010] Preferably, the inner sidewall of the first chute has multiple sets of fourth chute; the fourth chute is slidably connected to a limiting plate; the fourth chute and the limiting plate are connected by a spring rod; during operation, this step utilizes the multiple sets of limiting plates installed inside the first chute, which, under the support of the spring rod, provide a jerking effect during the movement of the positioning block, generating vibration to shake off the mud and sand impurities on the filter screen, leaving gaps for water flow, reducing the resistance increase caused by mud and sand impurities clogging the filter screen, and affecting the falling speed of the positioning block.

[0011] Preferably, the pair of support brackets is configured in multiple segments, and each segment of the support bracket is connected by a storage plate; the storage plate has through slots on both sides, and the ends of the support brackets slide inside the storage plate; an electric actuator is slidably connected to the middle of the support rod; during operation, this step utilizes the segmented configuration of the support brackets to support shafts of different sizes, reducing soil collapse and increasing the adaptability of the equipment in different environments.

[0012] Preferably, a magnet is attached to the end of the main support plate away from the positioning block; a magnet with magnetic repulsion is fixed to the side wall of the connecting column at a position corresponding to the end of the main support plate; during operation, this step utilizes the magnets with magnetic attraction installed on the end of the main support plate and the side wall of the connecting column to increase the restriction effect on the main support plate when it is in the placement state, reducing the possibility of the main support plate unfolding and causing damage to the surrounding materials.

[0013] Preferably, the bottom storage plate has multiple sets of rollers rotatably connected to its sidewall; the rollers have multiple sets of protrusions fixed to their sidewalls; during operation, this step utilizes the rotatable effect of the rollers to reduce the friction between the support frame and the shaft sidewall during movement, assisting workers in moving the support frame. At the same time, the protrusions installed on the roller sidewalls can provide a shaking effect during movement, causing vibration to shake off the mud and sand on the support frame, connecting rods, and telescopic fence, reducing adhesion.

[0014] Preferably, multiple sets of baffle plates are fixed to the top and bottom surfaces of the filter screen; the baffle plates are arc-shaped, and their two ends contact the side walls of the main support plate and the side support plate, respectively; during operation, this step utilizes the multiple sets of baffle plates installed on the top and bottom surfaces of the filter screen to block debris in the water, keeping the debris accumulated at the bottom of the filter screen, reducing the amount of debris that may leak out from the gap between the filter screen and the telescopic fence during the movement of the filter screen, thus preventing blockages during water extraction and affecting the construction progress.

[0015] Preferably, a fifth groove is provided on the side wall of the connecting column at the location of the second connecting rope; the second connecting rope is wound inside the fifth groove; during operation, this step utilizes the fifth groove on the side wall of the connecting column to reduce the occurrence of the second connecting rope sliding up and down on the connecting column during the rotation of the connecting column, thereby maintaining the stability of the equipment during use.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention provides an advanced support frame for a vertical tunneling machine. By utilizing the blocking effect of the support frame, connecting rods, and telescopic fence, the bottom of the shaft can be supported around the shaft, maintaining pressure around the soil layer during water extraction and reducing the possibility of collapse. Simultaneously, a movable positioning block can enter the support frame and, through the filtering effect of the filter screen, compress impurities at the bottom of the shaft, causing debris to accumulate at the bottom of the support frame. This reduces the movement of mud and sand at the bottom of the shaft with the pumping equipment during water extraction, preventing voids at the bottom and potential soil collapse. Furthermore, the filter screen also filters water during pumping, reducing the amount of debris entering the pumping pipes and preventing blockages that could affect pumping efficiency.

[0018] 2. This invention provides an advanced support bracket for a vertical tunneling machine. By utilizing the rotatable effect of the connecting column, the filter screen can be unfolded to suppress debris in the water when drainage operations are required. At the same time, when drainage operations are not required, the rotation of the No. 1 rotating shaft can drive the main support plate to retract and move closer to the connecting column, thereby reducing the space occupied by the filter screen when it is in a flat state and improving space utilization.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-5As shown, a vertical tunneling machine advance support frame includes a support frame 1; a pair of the support frames 1 are arranged vertically and vertically; multiple sets of connecting rods 11 are fixedly connected between the pair of support frames 1; multiple sets of support rods 12 are provided inside the support frame 1; a positioning block 13 is provided at the top of the support frame 1; multiple sets of filter screens 14 are provided on the side wall of the positioning block 13; a main support plate 15 is fixedly connected to the middle of each of the multiple sets of filter screens 14; side support plates 16 are fixedly connected to the side walls of each of the multiple sets of filter screens 14; the multiple sets of side support plates 15... The gap between 6 is larger than the diameter of the support rod 12; telescopic fences 17 are installed between multiple sets of connecting rods 11; during operation, when the vertical tunneling machine has finished excavating and it is necessary to extract water from the well, the support bracket 1, connecting rods 11, and telescopic fences 17 installed on the bottom side wall of the well can support the surrounding walls. At this time, the workers can use the support effect of the main support plate 15 and the side support plate 16 to lift the positioning block 13 from the top of the support bracket 1 and place the filter screen 14. The gaps between the multiple sets of side support plates 16 allow the filter screen 14 to pass through the support rod 12 and enter the support frame 1. This suppresses debris in the water source, causing it to be squeezed and pushed into the bottom of the well, facilitating water extraction. This step utilizes the blocking effect of the support frame 1, connecting rod 11, and telescopic fence 17 to support the bottom of the shaft, maintaining pressure around the soil layer during water extraction and reducing the risk of collapse. Simultaneously, the movable positioning block 13 can enter the support frame 1 and, through the filtering effect of the filter screen 14, squeeze impurities at the bottom of the shaft, causing them to accumulate at the bottom of the support frame 1. This reduces the movement of mud and sand at the bottom of the shaft with the pumping equipment during water extraction, preventing voids and soil collapse. Furthermore, the filter screen 14 acts as a filter during pumping, reducing debris from entering the pumping pipe and causing blockages that could affect pumping efficiency.

[0031] Please see Figure 3-4As shown, the main support plate 15 and the positioning block 13 are rotatably connected by a first rotating shaft 2; the two side walls of the main support plate 15 are hinged to a second rotating shaft 21 by torsion springs; the end of the side support plate 16 is connected to the side wall of the second rotating shaft 21; a first connecting rope 22 is wound around the shafts of both the second rotating shaft 21 and the first rotating shaft 2; a connecting post 23 is rotatably connected to the top of the positioning block 13; multiple sets of the main support plates 15 are fixedly connected to the top of the second connecting rope 24; the other end of the second connecting rope 24 is wound around the side wall of the connecting post 23; during operation, when the operator uses the positioning block 13, the second connecting rope 24 can be wound and contracted by rotating the connecting post 23, so that the second connecting rope 24 pulls the main support plate 15, causing the main support plate 15 to rotate, so that when the positioning block 13 is stored, rotating the connecting post 23 causes the main support plate 15 to contract and move the side support plate 16 towards the connecting post 23. The connecting column 23 is brought closer together to reduce the space required for the positioning block 13. When in use, the connecting column 23 is rotated in the opposite direction to relax the second connecting rope 24, causing the main support plate 15 to be in a parallel state. At this time, the rotation of the first rotating shaft 2 will provide a pulling effect on the first connecting rope 22, causing the side support plate 16 to rotate. This, in conjunction with the state of the main support plate 15, flattens and contracts the filter screen 14. When 15 moves towards the side wall of 23, the rotation of multiple sets of 16 reduces the contact between them and reduces the jamming caused by the contact between multiple sets of 16. This step utilizes the rotatable effect of the connecting column 23. When drainage is required, the filter screen 14 can be unfolded to suppress debris in the water. At the same time, when drainage is not required, the rotation of the first rotating shaft 2 can cause the main support plate 15 to contract and move closer to the connecting column 23, thereby reducing the space occupied by the filter screen 14 when it is in a flat state and improving space utilization.

[0032] Please see Figure 2-6 As shown, a positioning post 3 is fixedly connected to the middle of the support rod 12; a first groove 31 is opened on the top of the positioning post 3; multiple sets of second grooves 32 are opened on the side wall of the first groove 31; the second grooves 32 are located between each pair of support rods 12; the diameter of the main support plate 15 is smaller than the diameter of the second groove 32; during operation, when the worker is feeding the filter screen 14, the positioning post 3 installed in the middle of the support rod 12 can allow the positioning block 13 to enter through the opening of its first groove 31, so that the main support plate 15 drives the filter screen 14 to move in the second groove 32. By fixing the position of the positioning post 3, the filter screen 14 is kept in the same vertical state during the pressing of debris. This step, by using the installation of the positioning post 3, can keep the positioning block 13 in the center position of the support bracket 1 during the falling process, reduce the collision between the filter screen 14 and the side wall of the support bracket 1, and increase the stability of the filter screen 14 when in contact with debris.

[0033] Please see Figure 7 As shown, the top of the first chute 31 is provided with a third chute 4; the top of the third chute 4 is hinged with multiple sets of third rotating shafts 42 by torsion springs; the side walls of the third rotating shafts 42 are fixed with guide plates 41; the multiple sets of guide plates 41 are inclined towards the center of the positioning post 3; during operation, when the worker puts the positioning block 13 in, the guide plates 41 inclined on the top of the positioning post 3 can guide the falling positioning block 13 under the effect of the inclined surface, so that it can smoothly enter the first chute 31 and fall down to suppress the debris in the water. This step utilizes the guiding effect of the guide plates 41 to assist the positioning block 13 in entering the first chute 31 when it falls, reducing the occurrence of jamming between the positioning block 13 and the bottom of the positioning post 3, which would affect the normal falling of the positioning block 13 and thus affect the work progress.

[0034] Please see Figure 7 As shown, the inner sidewall of the first slide 31 has multiple sets of fourth slides 5; the fourth slide 5 is slidably connected to a limiting plate 51; the fourth slide 5 and the limiting plate 51 are connected by a spring rod 52; during operation, as the positioning block 13 moves into the first slide 31, as the positioning block 13 continuously contacts the multiple sets of limiting plates 51, the positioning block 13 can experience a jerking effect during movement, shaking the mud and sand on the filter screen 14 and leaving gaps for water to pass through. This step utilizes the multiple sets of limiting plates 51 installed inside the first slide 31, which, under the support of the spring rod 52, provide a jerking effect during the movement of the positioning block 13, generating vibration, shaking the mud and sand impurities on the filter screen 14, leaving gaps for water to pass through, reducing the resistance increase caused by mud and sand impurities clogging the filter screen 14, and affecting the falling speed of the positioning block 13.

[0035] Please see Figure 2 As shown, the pair of support brackets 1 are multi-segmented, and each segment of support bracket 1 is connected by a storage plate 8. The storage plate 8 has through slots on both sides, and the ends of the support brackets 1 slide inside the storage plate 8. An electric actuator 81 is slidably connected to the middle of the support rod 12. During operation, when workers are supporting shafts of different sizes, the segmented design of the support brackets 1, combined with the presence of the storage plate 8, allows for changes in their length. The pushing effect of the electric actuator 81 causes the support rod 12 to retract, making contact support between the sidewall of the support bracket 1 and the sidewall of the shaft. This step, utilizing the segmented design of the support brackets 1, allows for support in shafts of different sizes, reducing soil collapse and increasing the equipment's adaptability to different environments.

[0036] Please see Figure 1-5As shown, a magnet is attached to the end of the main support plate 15 away from the positioning block 13; a magnet with magnetic repulsion is fixed to the side wall of the connecting column 23 at a position corresponding to the end of the main support plate 15; during operation, as the operator rotates the connecting column 23 to retract and place the main support plate 15, the magnets installed on the end of the main support plate 15 can provide a pulling effect on the main support plate 15 under the magnetic attraction effect as the distance between the magnets and the connecting column 23 decreases. This step utilizes the magnetic attraction between the magnets installed on the end of the main support plate 15 and the side wall of the connecting column 23 to increase the restriction effect on the main support plate 15 when it is in the placement state, reducing the possibility of the main support plate 15 unfolding and causing damage to the surrounding materials.

[0037] Please see Figure 2 As shown, the bottom storage plate 8 has multiple sets of rollers 6 rotatably connected to its side wall; the rollers 6 have multiple sets of protrusions 61 fixed to their side walls; during operation, when the worker lowers and installs the support bracket 1, the storage plate 8 installed on the side wall of the support bracket 1 can be lowered with the assistance of the rotatable rollers 6 on its own side wall. After contacting the side wall of the shaft, the rolling effect of the rollers 6 can assist in the movement. This step utilizes the rotatable effect of the rollers 6 to reduce the friction between the support bracket 1 and the side wall of the shaft during the movement, assisting the worker in moving the support bracket 1. At the same time, the protrusions 61 installed on the side wall of the rollers 6 can provide a shaking effect during the movement, causing it to vibrate and shake off the mud and sand on the support bracket 1, connecting rod 11, and telescopic fence 17, reducing adhesion.

[0038] Please see Figure 3 As shown, multiple sets of baffle plates 9 are fixed to the top and bottom surfaces of the filter screen 14. The baffle plates 9 are arc-shaped, and their two ends contact the side walls of the main support plate 15 and the side support plate 16, respectively. During operation, as the filter screen 14 moves within the water source, the baffle plates 9 installed on the top and bottom surfaces of the filter screen 14 can partially block debris in the water, reducing the likelihood of debris rolling over at the bottom of the filter screen 14 during the pressing process. This step utilizes multiple sets of baffle plates 9 installed on the top and bottom surfaces of the filter screen 14 to block debris in the water, keeping the debris concentrated at the bottom of the filter screen 14. This reduces the likelihood of debris leaking out from the gap between the filter screen 14 and the telescopic fence 17 during the movement of the filter screen 14, which could lead to blockages during water extraction and affect the construction progress.

[0039] Please see Figure 4As shown, a fifth groove 101 is provided on the side wall of the connecting column 23 at the location of the second connecting rope 24; the second connecting rope 24 is wound inside the fifth groove 101; during operation, as the connecting column 23 rotates, the fifth groove 101 on the side wall of the connecting column 23 allows the second connecting rope 24 to be wound, causing the second connecting rope 24 to gradually accumulate inside the fifth groove 101. This step utilizes the fifth groove 101 on the side wall of the connecting column 23 to reduce the occurrence of the second connecting rope 24 sliding up and down on the connecting column 23 during the rotation of the connecting column 23, thus maintaining the stability of the equipment during use.

[0040] Working Principle: After the vertical tunneling machine completes excavation, when water needs to be extracted from the well, the support frame 1, connecting rod 11, and telescopic fence 17 installed on the bottom side wall of the well can support the surrounding walls. At this time, the operator can hoist and drop the positioning block 13 from the top of the support frame 1. The filter screen 14 is unfolded using the support effect of the main support plate 15 and the side support plates 16. The gaps between the multiple sets of side support plates 16 allow the filter screen 14 to pass through the support rod 12 and enter the interior of the support frame 1, suppressing debris in the water source. The debris is then forced into the bottom of the well by the filter screen 14, facilitating the operator's absorption and extraction of the water. During the operation of the positioning block 13, it can be rotated... The moving connecting column 23 drives the second connecting rope 24 to wind and contract, causing the second connecting rope 24 to pull on the main support plate 15, causing the main support plate 15 to rotate. When storing the positioning block 13, rotating the connecting column 23 causes the main support plate 15 to contract and move the side support plate 16 closer to the connecting column 23, reducing the space required for the positioning block 13. In use, rotating the connecting column 23 in the opposite direction relaxes the second connecting rope 24, causing the main support plate 15 to be in a parallel state. At this time, the rotation of the first rotating shaft 2 provides a pulling effect on the first connecting rope 22, causing the side support plate 16 to rotate. This, in conjunction with the state of the main support plate 15, flattens and contracts the filter screen 14, allowing multiple sets of 16 to move towards the side wall of 23. Rotation reduces contact between components and minimizes jamming caused by contact between multiple groups 16. During the process of the operator delivering the filter screen 14, the positioning post 3 installed in the middle of the support rod 12 can allow the positioning block 13 to enter through the opening of its first slide 31, causing the main support plate 15 to move the filter screen 14 in the second slide 32. The fixed position of the positioning post 3 ensures that the filter screen 14 remains in a vertical position during the process of pressing debris. During the delivery of the positioning block 13, the guide plate 41 inclined on the top of the positioning post 3 can guide the falling positioning block 13 under the effect of the slope, allowing it to smoothly enter the first slide 31 and fall to press debris in the water. During the movement inside the No. 1 chute 31, as the positioning block 13 continuously contacts multiple sets of limiting plates 51, it creates a jerking effect, shaking the mud and sand on the filter screen 14 and leaving gaps for water flow. When workers support vertical shafts of different sizes, the segmented design of the support bracket 1, combined with the presence of the storage plate 8, allows for changes in its length. The push effect of the electric actuator 81 causes the support rod 12 to retract, bringing the side wall of the support bracket 1 into contact with the side wall of the vertical shaft. As workers rotate the connecting column 23 to retract and place the main support plate 15, the magnets installed at the end of the main support plate 15 decrease in distance from the connecting column 23.The magnets installed on the main support plate 15 and the connecting column 23 can provide a pulling effect on the main support plate 15 under the magnetic attraction effect. During the lowering and installation of the support bracket 1, the storage plate 8 installed on the side wall of the support bracket 1 can be lowered with the assistance of the rotatable rollers 6 on its own side wall. After contacting the side wall of the shaft, the rolling effect of the rollers 6 can assist in the movement. During the movement of the filter screen 14 in the water source, the blocking plates 9 installed on the top and bottom surfaces of the filter screen 14 can partially block the debris in the water, keeping the debris at the bottom of the filter screen 14 from rolling during the pressing process. During the rotation of the connecting column 23, the No. 5 slide groove 101 opened on the side wall of the connecting column 23 can be used for the No. 2 connecting rope 24 to be wound, so that the No. 2 connecting rope 24 gradually accumulates inside the No. 5 slide groove 101.
