Description

Technical Field

[0001] The invention belongs to the technical field of soft soil solidification, in particular to soft soil solidification equipment. Background Art

[0002] Soft soil solidification technology is a technology that changes the properties of soft soil foundation through physical and chemical means. Its core lies in mixing special curing agents (such as cement, lime, fly ash, polymer materials, etc.) with soft soil, evenly distributing the curing agents in the soft soil through mixing equipment, and initiating a series of physical and chemical reactions. These reactions can reduce the water content of soft soil, enhance its bonding strength, and ultimately form a composite stable base with a certain bearing capacity.

[0003] Existing soft soil solidification technologies include physical drainage and heating solidification, and the addition of chemical substances to solidify the soft soil. Among them, the more commonly used method is to add composite chemical substances into the soft soil to improve the properties of the soil and enhance its strength and stability. Specifically, it requires the use of a mixing head installed on the mechanical arm of the excavator body. While the "Y"-shaped mixing head is fully stirring, a soft soil solidifier that has been mixed with water is added, so that soft soil and soft soil solidifiers at different depths are repeatedly stirred and mixed to solidify the soft soil.

[0004] However, although the existing mixing heads can fully mix the soil in the horizontal and vertical directions, and can use the mobility of the excavator's mechanical arm to penetrate deep into the soil to solidify the soft soil, due to the small area of ​​the mixing head and the use of radial spiral mixing, when solidifying a large area of ​​shallow soft soil, only tedious mixing operations can be repeated, and the efficiency is lower than expected.

[0005] Therefore, it is necessary to propose a soft soil solidification equipment that can effectively solidify shallow soft soil and repeatedly mix the soft soil solidifier and soft soil, thereby ensuring the efficiency of large-area shallow soft soil solidification operations while retaining the ability to solidify deep soft soil operations. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a soft soil solidification equipment, which, by integrating the chain transmission structure design, can lay down the tooth chain and stir, mix and solidify the shallow soft soil in a straight line at the same time, and can make the input soft soil solidifying agent and the soft soil evenly mixed, so that the shallow soft soil solidification operation is more efficient and reduces unnecessary solidification costs.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a soft soil solidification equipment, including an excavator body and a controller arranged in the body, the end of the mechanical arm of the excavator body is detachably and rotatably connected to a support arm, a steering assembly is arranged in the support arm, a rotating groove is opened at the end of the support arm away from the mechanical arm, a rotating motor is fixedly connected to the rotating groove wall, the output shaft of the rotating motor is coaxially and fixedly connected to a rotating wheel, the outer periphery of the rotating wheel is fixedly connected to a frame, a digging assembly and a gyroscope are arranged on the frame, a conveying assembly is arranged on the inner side of the frame, the gyroscope and the conveying assembly are both connected to the controller signal, the steering assembly is used to realize radial rotation of the support arm; the digging assembly is used for excavating and stirring shallow soft soil; the conveying assembly is used to convey soft soil solidifying agent in several directions in the frame.

[0008] The principle of the basic scheme is: after the equipment is started, the excavator body provides power, and the mechanical arm sends the support arm and the digging assembly to the working position. The steering assembly adjusts the radial rotation angle of the support arm so that the digging assembly is aligned with the shallow soft soil area to be solidified. The rotating motor starts, driving the rotating wheel and the frame to rotate, and the digging assembly begins to dig and stir the soft soil. At the same time, the conveying assembly starts to evenly spray or inject the soft soil curing agent into the stirred soft soil. Through the continuous stirring of the digging assembly, the soft soil and the curing agent are fully mixed to form a uniform solidified soil body. While the digging assembly is working, the excavator body can move slowly, so that the soft soil is stirred and mixed while passing through the inside of the frame, thereby improving the efficiency of soft soil solidification.

[0009] The beneficial effects of the basic scheme are: 1. The integration of chain transmission structure design realizes the rapid excavation and mixing of large areas of shallow soft soil, improving the efficiency of solidification operations.

[0010] 2. The design of the conveying component ensures that the soft soil solidifier can be evenly distributed in the stirred soft soil, improving the solidification effect.

[0011] 3. The design of the steering assembly and the rotary motor enables the equipment to flexibly adjust the working posture and direction to meet the needs of different working environments. At the same time, the structure of the chain trencher also enables the present invention to have the ability to perform deep soil solidification operations.

[0012] 4. By improving the efficiency and quality of curing operations, unnecessary curing costs and time waste are reduced.

[0013] Furthermore, the digging assembly includes an digging motor, which is fixedly connected to the inner wall of one end of the frame, and the output shaft of the digging motor is coaxially fixedly connected to the digging gear, and the digging gear is meshed with a digging tooth chain. The outer periphery of the digging tooth chain is detachably connected to a plurality of decks, and conveying gaps are provided between adjacent decks. A plurality of inclined guide plates and symmetrical digging teeth are fixedly connected to the decks, and the width of the deck is greater than the frame spacing, and the digging tooth chain surrounds the outer periphery of the frame.

[0014] The beneficial effects of the basic solution are: 1. Driven by the digging motor, the digging tooth chain can rotate continuously and stably, realizing efficient digging and mixing of soft soil in the lateral direction. The inclined guide plate and digging tooth design on the deck further enhance the digging and mixing effect, allowing the soft soil and curing agent to be mixed more fully.

[0015] 2. The deck can be detachably connected to the outer periphery of the digging tooth chain. This design allows the equipment to flexibly adjust the number and layout of the deck according to different working environments and soft soil properties. The digging tooth chain surrounds the outer periphery of the frame, making the frame design also flexible and able to adapt to the needs of soft soil curing operations of different depths and widths.

[0016] 3. The earthmoving motor is fixedly connected to the inner wall of the frame through a support shell. This design enhances the structural stability of the earthmoving assembly and improves the durability and service life of the equipment. The deck, inclined guide plate, earthmoving teeth and other components are made of wear-resistant and corrosion-resistant materials, which can adapt to harsh working environments and reduce maintenance and replacement costs.

[0017] 4. By optimizing the design of the earthmoving components, the operating efficiency of the equipment is improved, and energy consumption and costs are reduced. The detachable design of the earthmoving tooth chain and deck facilitates the maintenance of the equipment, reducing downtime and repair costs.

[0018] Furthermore, symmetrical digging teeth are located on both axial sides of the inclined guide plate, and the digging teeth are facing both sides of the deck.

[0019] The basic solution has the following beneficial effects: the symmetrical teeth are located on both sides of the axial direction of the inclined guide plate and face both sides of the deck. This design enables the tooth chain to dig and mix soft soil more efficiently when rotating. The cutting and flipping action of the teeth and the guiding action of the inclined guide plate together enable the soft soil to be mixed evenly and fully.

[0020] Furthermore, the earthmoving motor is fixedly connected to the inner wall of the frame via a supporting shell.

[0021] The beneficial effects of the basic scheme are: 1. The earthmoving motor is fixedly connected to the inner wall of the frame through the support shell, which can effectively prevent the motor from shaking or moving during operation and improve the overall stability of the equipment. This is crucial to ensure the normal operation of the equipment in a complex operating environment.

[0022] 2. The support shell can disperse the vibration and impact force generated by the earthmoving motor and reduce the damage to the motor. This can not only extend the service life of the motor, but also reduce the maintenance and replacement costs of the equipment.

[0023] Furthermore, the conveying assembly includes annular slide grooves located on both sides of the rotating wheel, and the annular slide grooves include an inner half ring and an outer half ring. The inner half rings are slidably matched with the outer half rings, the inner half rings are close to the rotating wheel, and the outer half rings are far away from the rotating wheel. The inner half rings are fixedly connected to the output shaft of the rotating motor, and the outer half rings are rotatably connected to the output shaft of the rotating motor. The inner half rings are connected with conveying pipes, which are laid in a ring shape along the frame, and a plurality of conveying ports are opened on the outer wall of the conveying pipes. The side of the outer half ring away from the rotating wheel is connected with a supply pipe, and the supply pipes pass through the wall of the rotating groove and extend upward along the support arm.

[0024] The beneficial effects of the basic scheme are: 1. The design of the annular chute and the conveying pipe realizes the uniform spraying of the curing agent. The inner half ring rotates with the rotating wheel, driving the conveying pipe to move along the frame, and spraying the curing agent evenly through the deck conveying gap into the stirred soft soil.

[0025] 2. The design of the conveying assembly has strong adaptability. The inner and outer half rings of the annular chute slide together to meet the requirements of different speeds and torques, and prevent the supply pipe from being affected by the rotating motor. The overall design of the conveying assembly is simple and compact, which is easy to maintain and reduce maintenance costs.

[0026] Furthermore, the delivery port is fixedly connected with an electric-controlled valve and a nozzle, the electric-controlled valve is connected with the controller signal, and the nozzle opening near the two ends of the frame is smaller than the nozzle in the center.

[0027] The beneficial effect of the basic scheme is that the setting of the electric control valve effectively prevents the backflow of the curing agent and soft soil, ensuring the stability and continuity of the spraying. This not only improves the spraying efficiency, but also avoids the waste of resources and environmental pollution.

[0028] Furthermore, a protective shell is fixedly connected to one side of the delivery pipe away from the frame, and a plurality of stirring rods are fixedly connected to the protective shell.

[0029] The beneficial effects of the basic solution are: the design of the protective shell and the stirring rod further enhances the stirring effect. While the soft soil passes through the frame, the stirred soft soil is stirred for the second time, which promotes the uniform mixing of the curing agent and the soft soil. The design of the protective shell protects the conveying pipe from external damage and prolongs the service life of the equipment.

[0030] Further, the supply pipe is made of an elastic material.

[0031] The beneficial effect of the basic solution is that the supply pipe is made of elastic material, which can adapt to the vibration and friction during operation and ensure a stable supply of curing agent.

[0032] Furthermore, the steering assembly includes a gear shaft fixedly connected to the end of the excavator body mechanical arm, a steering groove is opened inside the end of the support arm that is rotatably connected to the mechanical arm, the gear shaft is located inside the steering groove, a steering motor is fixedly connected in the steering groove, a steering gear is coaxially fixedly connected to the output shaft of the steering motor, and the steering gear is meshed with the gear shaft.

[0033] The beneficial effects of the basic solution are: 1. The steering motor drives the steering gear to rotate, which in turn drives the support arm to rotate radially, thus realizing flexible adjustment of the working direction of the equipment. This design enables the soft soil solidification equipment to easily cope with different working environments and terrain conditions, improving the adaptability and flexibility of the equipment.

[0034] 2. The meshing transmission of the gear shaft and the steering gear has the characteristics of high transmission efficiency and strong load-bearing capacity, which can ensure the stable operation of the steering assembly under long-term and high-load working conditions. The structure of the steering assembly is relatively simple and easy to disassemble and repair. When the equipment fails, the problem can be quickly located and repaired, reducing downtime and maintenance costs.

[0035] 3. The flexibility and stability of the steering assembly help improve the operating efficiency of the soft soil solidification equipment. By quickly adjusting the working direction, the equipment can cover the working area more efficiently, reducing repetitive labor and ineffective working time.

[0036] Furthermore, the supply pipe is fixedly connected to the outer periphery of the support arm, the upwardly extending end of the supply pipe is connected to the output end of the supply pump, the input end of the supply pump is connected to the soft soil curing agent mixing tank, and the supply pump is connected to the controller signal.

[0037] The benefits of the basic solution are: 1. The fixed connection between the supply pipe and the outer periphery of the support arm enhances the structural stability of the entire delivery system. This design reduces the risk of loosening or falling off of the pipe due to vibration or external force, ensuring the continuity and stability of the curing agent delivery.

[0038] 2. This design has strong adaptability and can be applied to different types of soft soil curing working environments. Whether it is large-scale engineering projects such as highways, railways, airport runways, or other occasions that require soft soil curing, this equipment can provide efficient and stable curing agent delivery solutions.

DETAILED DESCRIPTION

[0044] The following is further described in detail through specific implementation methods:

The excavation gear 17 is meshed with a excavation tooth chain 25. The outer periphery of the excavation tooth chain 25 is connected with a number of decks 8 by detachable buckles. Conveying gaps 9 are provided between adjacent decks 8. A number of inclined guide plates 10 and symmetrical excavation teeth 11 are welded on the decks 8. The width of the deck 8 is greater than the interval of the frame 5. The excavation tooth chain 25 surrounds the outer periphery of the frame 5. The symmetrical excavation teeth 11 are located on both axial sides of the inclined guide plate 10, and the excavation teeth 11 are all facing both sides of the deck 8. The excavation motor 18 is welded to the inner wall of the frame 5 through a support shell 14.

[0047] The conveying assembly is used to convey the soft soil curing agent in several directions in the frame 5. The conveying assembly includes an annular slide 15 located on both sides of the rotating wheel 16. The annular slide 15 includes an inner half ring 23 and an outer half ring 24. The inner half ring 23 is slidably matched with the slide of the outer half ring 24. The inner half ring 23 is close to the rotating wheel 16, and the outer half ring 24 is far away from the rotating wheel 16. The inner half ring 23 is welded to the output shaft of the rotating motor 4, and the outer half ring 24 is slidably sleeved with the output shaft of the rotating motor 4. The inner half ring 23 is connected to the conveying pipe 12, and the conveying pipe 1 2 is laid along the frame 5 in an annular shape, a plurality of delivery ports 13 are opened on the outer wall of the delivery pipe 12, a supply pipe 2 is connected to the side of the outer semi-ring 24 away from the rotating wheel 16, the supply pipe 2 passes through the wall of the rotating groove 3 and extends upward along the support arm 1, an electric control valve and a nozzle are welded in the delivery port 13, the electric control valve is connected to the controller signal, the nozzle opening near the two ends of the frame is smaller than the nozzle in the center, a protective shell 6 is welded on the side of the delivery pipe 12 away from the frame 5, a plurality of stirring rods 7 are welded on the protective shell 6, and the supply pipe 2 is made of elastic material.

[0048] The supply pipe 2 is bonded to the outer periphery of the support arm 1 , the end of the supply pipe 2 extending upward is connected to the output end of the supply pump, the input end of the supply pump is connected to the soft soil curing agent mixing tank, and the supply pump is connected to the controller signal.

[0049] The specific implementation process is as follows: When solidifying a large area of ​​shallow soft soil, it is necessary to use a mixing head to penetrate the soft soil step by step to mix and stir the soft soil solidifier. Due to the small area of ​​the mixing head, the operating efficiency is not ideal. For this reason, a digging component is designed by integrating a chain transmission structure.

[0050] like Figure 2 As shown, the support arm 1 installed on the mechanical arm of the excavator body supports the rotating motor 4, and the rotating wheel 16 welded on the output shaft of the rotating motor 4 is welded to the frame 5, so that the rotating motor 4 on the support arm 1 can rotate the frame 5, which is convenient for flexible adjustment of the end of the frame 5. When solidifying soft soil, the digging motor 18 is turned on, and the digging gear 17 on the output shaft drives the digging tooth chain 25 to move circumferentially around the outer periphery of the frame 5, thereby driving the deck 8 fixed thereon, and the inclined guide plate 10 and the digging teeth 11 on the deck 8 dig the soft soil and push it to the lateral sides of the deck 8. When deep soft soil solidification is required, the frame 5 is erected, and the entire frame 5 is deeply inserted into the soft soil for stirring and mixing.

[0051] At the same time, the blended soft soil curing agent is input along the support arm 1 through the supply pipe 2. The supply pipe 2 directly passes through the support arm 1 and is connected to the outer semi-ring 24. The outer semi-ring 24 will not rotate with the rotation of the frame 5 on the rotating motor 4, so as to avoid the supply pipe 2 being affected by the rotation. The soft soil curing agent enters the inner semi-ring 23 through the annular slide groove 15, and then enters the delivery pipe 12 through the inner semi-ring 23, and is evenly dispersed into the excavated soft soil through the delivery ports 13 distributed at different positions. On the one hand, the electric control valve is used to prevent the excavated soft soil from entering the delivery port 13 and blocking the delivery pipe 12. Since the annular delivery pipe 12 is located on the inner side of the frame 5 and needs to have the ability to rotate with the frame 5, the inner semi-ring 23 is welded to the output shaft of the rotating motor 4 and rotates with it. The soft soil curing agent output from the delivery port 13 is sprayed into the soft soil from the inner side of the frame 5 through the delivery gap 9 between the decks 8 to fully ensure the mixing efficiency of the soft soil and the soft soil curing agent.

[0052] The main working mode of the present invention is to erect the frame 5 to carry out deep soft soil excavation, stirring and fixing, or to place the frame 5 horizontally to carry out shallow soft soil solidification in a larger range. Only in these two postures of the frame 5, by receiving the gyroscope angular velocity signal, the controller controls the supply pump to reach the maximum soft soil solidifier supply flow rate. When the rotating motor 4 rotates the frame 5 to 45 degrees with the mechanical arm, the controller controls the supply pump to enter the minimum supply flow rate or stop supplying, thereby avoiding the waste of soft soil solidifier when the frame 5 rotates or the excavator body changes direction, ensuring sufficient supply of soft soil solidifier in the working state, and reducing the possibility of external impurities entering the delivery port 13 and clogging it.

[0053] In addition, when deep soft soil solidification is being carried out, the gyroscope on the frame 5 detects the posture of the frame 5 at this time, and transmits a signal to the controller to open the deep soft soil excavation and solidification mode. At this time, the gyroscope continuously detects the angular velocity change of the frame 5 landing and digging, so as to control the electric control valves entering below the ground to open step by step through the controller. At the beginning, the electric control valves are opened the least, and the opened electric control valves correspond to the nozzles with smaller openings. Under the premise of the same soft soil solidifier flow rate, the speed of the soft soil solidifier spraying reaches the fastest at this time, thereby helping the deck 8 and the digging teeth 11 to moisten the soft soil that has not been excavated, reducing the difficulty of excavation. When the frame 5 gradually goes deeper into the ground, the electric control valves are opened layer by layer, and the nozzles with larger openings in the center are also opened. The soft soil solidifier is continuously sprayed and mixed with the soft soil with greater pressure, and the flow rate of the delivered soft soil solidifier is fully utilized to stir the excavated soft soil, thereby promoting the mixing effect in the deep soft soil fixed excavation process.

[0054] When the shallow soft soil is being solidified, the gyroscope on the frame 5 detects the horizontal posture of the frame 5 at this time, and the shallow soft soil solidification mode is turned on by the controller. The gyroscope detects the orientation of the frame 5 at this time, and the controller controls the electric control valve close to the ground to open, and the shallow soft soil solidification begins. During the movement of the excavator body, the soft soil passes under the frame 5 and the inside of the frame 5. At this time, the conveying port 13 close to the ground continuously sprays the soft soil curing agent into the pushed soft soil through the conveying gap 9, and cooperates with the movement of the deck 8, the movement of the digging teeth 11, the inclined guide plate 10 and the stirring rod 7 to strengthen the stirring of the shallow soft soil. The effect of the soft soil curing agent is fully exerted, and the curing quality and efficiency are improved. Since the opening of the nozzles at both ends is smaller than that of the central nozzle, the flow rate of the nozzles at both ends is always faster than that of the central nozzle, so that the soft soil below the two lateral ends of the frame 5 is more strongly impacted. When the shallow soft soil is solidified, the frame 5 can be swung back and forth in conjunction with the rotating motor 4, so that one end of the frame 5 is lifted to impact and gather the soft soil to the middle of the frame 5, and the gathered soft soil is mixed with a large amount of soft soil curing agent sprayed from the nozzle with a larger opening in the center, thereby promoting the overall mixing efficiency of the soft soil, enhancing the stirring effect, and avoiding the problem of uneven distribution of the soft soil after stirring and solidification.

[0055] Example 2

[0056] The difference from the above embodiment is that, as shown in the attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: the steering assembly is used to realize the radial rotation of the support arm 1, and the steering assembly includes a gear shaft 22 fixedly connected to the end pin of the mechanical arm of the excavator body, and a steering groove 19 is opened inside the end of the support arm 1 that is rotatably connected to the mechanical arm. The gear shaft 22 is located inside the steering groove 19, and a steering motor 20 is fixedly connected in the steering groove 19. A steering gear 21 is coaxially welded on the output shaft of the steering motor 20, and the steering gear 21 is meshed with the gear shaft 22.

[0057] The specific implementation process is as follows: the steering motor 20 rotates the steering gear 21 on the gear shaft 22, driving the support arm 1 welded with the steering motor 20 to rotate at the end of the excavator body mechanical arm, thereby giving the device a more flexible operation mode. When dealing with a large area of ​​shallow soft soil, the steering motor 20 and the rotating motor 4 are coordinated to make the device horizontal, and the support arm 1 and the frame 5 form an "L" shape. While digging and stirring the soil, start the excavator to make the excavated soft soil accumulate on the side of the frame 5. At this time, the inclined guide plate 10 can not only generate thrust in the direction of movement of the tooth chain, but also generate thrust in the direction of forward movement of the excavator, reducing the excavated soil remaining on the ground and reducing the uniformity of mixing the soft soil curing agent. At the same time, these soft soils are also mixed with the soft soil curing agent and leak to the rear through the gap inside the frame 5. The protective shell 6 can not only protect the conveying pipe 12, but the stirring rod 7 on it can also stir the soft soil again to provide uniformity with the soft soil curing agent. This working mode undoubtedly greatly improves the efficiency of solidifying large areas of shallow soft soil and reduces the consumption of manpower and material resources.
