Description

[0002] Waterless geological conditions usually refer to a state in which there is no water or very little water in the stratum. Boulder geological conditions refer to a state in which the stratum contains a large number of boulders of various sizes and shapes. Common construction equipment suitable for waterless and boulder geology includes pipe jacking machines, shield machines, etc. Among them, shield machines require the assistance of mixers during use. Mixers can mix and stir to make grouting materials, and grouting materials are an indispensable condition for the operation of shield machines.

[0003] In the initial stage of mixing the grouting material, a higher mixing speed is used to accelerate the mixing and uniform distribution of the raw materials. However, as the mixing process progresses, when the grouting material has reached a certain uniformity, an excessively high mixing speed may cause excessive wear of the material, generate heat or form bubbles, thereby affecting the performance of the grouting material. The mixing structure of the existing mixer cannot make adaptive adjustments to this characteristic, and it is impossible to reduce the wear of the mixing structure while improving the uniformity of mixing.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] As mentioned in the background technology of this application, it has been found that in the initial stage of mixing the grouting material, in order to accelerate the mixing and uniform distribution of the raw materials, the mixer adopts a higher stirring speed. However, as the mixing process proceeds, when the grouting material has reached a certain uniformity, an excessively high stirring speed may cause excessive wear of the material, generate heat or form bubbles, thereby affecting the performance of the grouting material. The stirring structure of the existing mixer cannot make adaptive adjustments to this characteristic, and cannot improve the uniformity of the mixing while reducing the wear of the stirring structure, which has certain defects.

[0037] In order to solve the above-mentioned defects, the present application discloses a construction device and method suitable for waterless and boulder-like geology. By setting up an adaptive stirring mechanism, it has two working modes, which can better stir the grouting material, reduce the wear of the stirring structure and improve the uniformity of stirring and mixing.

[0038] The following will describe in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0039] See also Figure 1 and Figure 2In an embodiment of the present invention, a construction device suitable for waterless and boulder-like geology includes a frame 1, a mixing box 2 is fixedly connected to the top surface of the frame 1, and a top cover 3 is fixedly connected to the top surface of the mixing box 2, a mixing chamber 32 is provided inside the mixing box 2, and a mixing shaft 4 is rotatably connected inside the mixing chamber 32, and a lower driving mechanism is fixedly connected inside the frame 1 for driving the mixing shaft 4 to rotate; two adaptive stirring mechanisms arranged in parallel up and down are fixedly connected to the outer side surface of the mixing shaft 4, and an intermittent feeding mechanism is provided at the top of the mixing shaft 4, a plurality of evenly distributed spiral feeding rods 19 are rotatably connected to the inside of the mixing chamber 32 near the edge, and an upper driving mechanism is provided inside the top cover 3 for driving the plurality of spiral feeding rods 19 to rotate synchronously. The adaptive stirring mechanism provided in the present application has two working modes, which can better stir the grouting material, and improve the uniformity of stirring and mixing while reducing the wear of the stirring structure.

[0040] In this embodiment, if Figure 2 and Figure 5 As shown, the adaptive stirring mechanism specifically includes: an inner ring body 6 sleeved on the outside of the stirring shaft 4, an outer ring body 5 is arranged outside the inner ring body 6, and the centers of the outer ring body 5 and the inner ring body 6 are both located on the central axis of the stirring shaft 4, three evenly distributed fixed stirring rods 7 are fixedly connected to the outer side of the stirring shaft 4 corresponding to the position of the inner ring body 6, and the side of the fixed stirring rod 7 is provided with a first slot 8 for the outer ring body 5 and the inner ring body 6 to pass through, and the two first slots 8 are respectively fixedly connected to the outer ring body 5 and the inner ring body 6, and a movable stirring rod 10 is arranged on one side of the fixed stirring rod 7, and the side of the movable stirring rod 10 is provided with a second slot 11 for the outer ring body 5 and the inner ring body 6 to pass through, and the two second slots 11 are respectively movably connected to the outer ring body 5 and the inner ring body 6, and the outer side of the outer ring body 5 is fixedly connected with three evenly distributed limit blocks 13. During the high-speed rotation of the stirring blade, a strong impact force will be generated on the grouting material. This impact force will not only cause eddy currents and shear forces in the mixing tank, but also increase the friction and wear between the mixing blades and the grouting materials. Figure 5 As shown, the adaptive stirring mechanism is in the first working mode at this time. At this time, the fixed stirring rod 7 and the movable stirring rod 10 are combined to form an integrated stirring rod, and the integrated stirring rod can reduce the friction and wear between the grouting material and enhance the overall structural strength, so as to better adapt to high-speed rotation. Figure 6 As shown, the adaptive stirring mechanism is in the second working mode at this time. The fixed stirring rod 7 and the movable stirring rod 10 are separated to form a split stirring rod. The split stirring rod can improve the stirring efficiency while rotating at a low speed, thereby improving the uniformity of stirring and mixing.

[0041] In this embodiment, if Figure 7 and Figure 8As shown, a strip groove 9 is provided on the side of the fixed stirring rod 7 between the two first slots 8, and a strip cutting plate 12 is fixedly connected to the side of the movable stirring rod 10 close to the fixed stirring rod 7, and the strip cutting plate 12 is located inside and matched with the strip groove 9. The provision of the strip groove 9 enables the passing slurry to rapidly collide with the strip cutting plate 12 at the rear, further breaking up the slurry and improving the mixing uniformity.

[0042] In this embodiment, if Figure 7 As shown, the side of the movable stirring rod 10 away from the fixed stirring rod 7 is an arc-shaped surface. The setting of the arc-shaped surface allows the adaptive stirring mechanism to reduce the friction and wear of the contact surface with the grouting material in the first working mode.

[0043] In this embodiment, if Figure 2 and Figure 4 As shown, the intermittent feeding mechanism specifically includes: a circular groove 27 opened at the center of the bottom end face of the top cover 3, the top end of the stirring shaft 4 is rotatably connected to the top wall of the circular groove 27, and the outside of the circular groove 27 is provided with an annular groove 29 connected thereto, the stirring shaft 4 in the circular groove 27 is symmetrically fixedly connected with connecting rods 28 on both sides, and one end of the connecting rod 28 extends to the annular groove 29 and is fixedly connected with an arc plate 30, the top end face of the top cover 3 is fixedly connected with an additive feeding bin 26 at a position corresponding to the arc plate 30, and the bottom end of the additive feeding bin 26 is connected to the annular groove 29, and the bottom end face of the annular groove 29 is provided with a plurality of through grooves 31 connected to the stirring chamber 32. Additives, such as thickeners, emulsifiers, etc., need to be added during the stirring process of the grouting material, and their delivery method has a direct impact on the performance of the grouting material. One-time delivery will cause the additives to be unevenly distributed in the grouting material, thereby affecting the overall performance of the material. Therefore, for these additives, the method of batching and gradually delivering them can better ensure that they are evenly distributed in the grouting material. The intermittent feeding mechanism of the present application can be driven by the rotating stirring shaft 4, so that the added additives are sequentially and intermittently added into the stirring chamber 32, which not only saves power source but also ensures that the additives are evenly distributed in the grouting material.

[0044] In this embodiment, if Figure 4 As shown, both ends of the arc plate 30 are inclined, and the centers of the arc plate 30 and the annular groove 29 are located on the central axis of the stirring shaft 4. Both ends of the arc plate 30 are inclined so that excess additives can be pushed into the circular groove 27 and then fall from the circular groove 27 into the stirring chamber 32, thereby preventing excess additives from affecting the rotation of the arc plate 30.

[0045] In this embodiment, if Figure 2 and Figure 4As shown, the upper driving mechanism specifically includes: an annular cavity 20 opened inside the top cover 3 near the edge position, a driven wheel 21 is rotatably connected to the position of each spiral feeding rod 19 inside the annular cavity 20, and the top end of the spiral feeding rod 19 penetrates into the annular cavity 20 and is fixedly connected to the corresponding driven wheel 21, a transmission cavity 33 connected to the annular cavity 20 is opened on one side inside the top cover 3, and a driving wheel 23 is rotatably connected inside the transmission cavity 33, a stepper motor 22 is fixedly connected to the position corresponding to the driving wheel 23 at the top surface of the top cover 3, and the bottom output shaft of the stepper motor 22 penetrates into the transmission cavity 33 and is fixedly connected to the driving wheel 23, and the driving wheel 23 and one driven wheel 21, as well as two adjacent driven wheels 21 are connected through a first belt 24 for transmission. The upper driving mechanism provided in the present application can drive several spiral feeding rods 19 to rotate synchronously, transport the bottom slurry upward, and thus improve the uniformity of mixing the bottom slurry and the top slurry in the stirring chamber 32. In addition, the adaptive stirring mechanism will generate a strong impact force on the grouting material during the rotation process, and this impact force will cause the grouting material to form eddy currents and shearing forces in the stirring chamber 32. Several spiral feeding rods 19 are distributed in a circular shape outside the adaptive stirring mechanism, and the eddy currents and shearing forces formed by the adaptive stirring mechanism further improve the stirring effect of the grouting material.

[0046] In this embodiment, if Figure 3 As shown, the lower driving mechanism specifically includes: a driving motor 14 fixed in the middle position inside the frame 1, a gear box 15 is fixedly connected to one side of the driving motor 14, and the input end of the gear box 15 is fixedly connected to the first transmission wheel 17, the output shaft of the driving motor 14 is fixedly connected to the second transmission wheel 16, and a second belt 18 is provided between the second transmission wheel 16 and the first transmission wheel 17 for transmission connection, and the bottom end of the stirring shaft 4 penetrates into the frame 1 and is fixedly connected to the top output end of the gear box 15. The lower driving mechanism can drive the stirring shaft 4 to rotate quickly and stably, thereby driving the intermittent feeding mechanism and the adaptive stirring mechanism to operate.

[0047] In this embodiment, if Figure 1 As shown, a feeding port 25 communicating with the stirring chamber 32 is fixedly connected to one side of the top surface of the top cover 3. The feeding port 25 is used to feed raw materials other than additives into the stirring chamber 32.

[0048] The present application also discloses a construction method applicable to waterless and boulder-like geology, using the above-mentioned construction device applicable to waterless and boulder-like geology, comprising the following steps:

[0049] Put the raw materials for preparing the grouting material into the stirring chamber 32 to prepare for stirring and mixing. Specifically, other raw materials except the additive are introduced into the stirring chamber 32 from the feeding port 25;

[0050] The lower driving mechanism operates to drive the stirring shaft 4 to rotate at a high speed, and the adaptive stirring mechanism is in the first working mode. Specifically, the driving motor 14 operates to drive the second transmission wheel 16 to rotate, and the second transmission wheel 16 drives the first transmission wheel 17 to rotate under the transmission action of the second belt 18, thereby causing the gear box 15 to operate, and the gear box 15 drives the stirring shaft 4 to rotate at a high speed. Figure 5 As shown, the adaptive stirring mechanism is in the first working mode at this time. Under the impact force caused by high-speed rotation, the fixed stirring rod 7 and the movable stirring rod 10 are combined to form an integrated stirring rod, and the strip cutting plate 12 is inserted into the strip groove 9. The arc surface of the movable stirring rod 10 directly faces the impact of the slurry. This integrated stirring rod can reduce the friction and wear between the grouting material and enhance the overall structural strength, and can better adapt to high-speed rotation.

[0051] After stirring for a preset time, the lower driving mechanism drives the stirring shaft 4 to reverse and the speed decreases. At this time, the adaptive stirring mechanism is in the second working mode. Specifically, the driving motor 14 runs in the opposite direction and reduces the speed, driving the stirring shaft 4 to reverse and reduce the speed. At this time, the adaptive stirring mechanism is in the second working mode. Since the fixed stirring rod 7 can no longer resist the movable stirring rod 10 at the back, the movable stirring rod 10 is separated from the fixed stirring rod 7 under the impact force brought by the rotation to form a split stirring rod. The movable stirring rod 10 moves away from the fixed stirring rod 7 along the outer ring body 5 and the inner ring body 6 until the movable stirring rod 10 is restricted by contact with the limit block 13. At this time, the strip cutting plate 12 is separated from the strip groove 9, and the setting of the strip groove 9 can allow the passing slurry to rapidly collide with the strip cutting plate 12 at the rear, further breaking up the slurry. This split stirring rod can increase the number of stirring rods, improve the stirring efficiency under the premise of low-speed rotation, and thereby improve the uniformity of stirring and mixing;

[0052] During the stirring process, the upper driving mechanism drives several spiral feeding rods 19 to rotate synchronously to transport the bottom slurry upward. Specifically, the stepper motor 22 drives the driving wheel 23 to rotate. The driving wheel 23 drives the corresponding driven wheel 21 to rotate under the transmission action of the first belt 24, and then drives all the driven wheels 21 to follow the synchronous rotation, so that each spiral feeding rod 19 rotates synchronously to transport the bottom slurry upward, and improves the uniformity of the mixing of the bottom slurry and the top slurry in the stirring chamber 32. In addition, the adaptive stirring mechanism will generate a strong impact force on the grouting material during the rotation process, and this impact force will cause the grouting material to form eddy currents and shear forces in the stirring chamber 32. Several spiral feeding rods 19 are distributed in a circular shape outside the adaptive stirring mechanism, and the eddy currents and shear forces formed by the adaptive stirring mechanism further improve the stirring effect of the grouting material. It should be noted that the intermittent feeding mechanism discharges the additives intermittently and orderly when feeding the additives. Specifically, the stirring shaft 4 rotates to drive the connecting rod 28 in the circular groove 27 to rotate, and the connecting rod 28 rotates to drive the arc plate 30 in the annular groove 29 to rotate. In the initial state, the arc plate 30 just blocks the bottom outlet of the additive feeding bin 26. When the arc plate 30 rotates to leave the bottom outlet of the additive feeding bin 26, the additives put into the additive feeding bin 26 enter the annular groove 29. When the arc plate 30 passes again, it will push the additives in the annular groove 29 forward. During the forward process, the additives fall into the stirring chamber 32 from the through groove 31 at the bottom of the annular groove 29 in sequence. Compared with one-time feeding, this feeding method can better ensure that the additives are evenly distributed in the grouting material. In addition, both ends of the arc plate 30 are inclined surfaces, which can push too much additives into the circular groove 27, and then fall from the circular groove 27 into the stirring chamber 32, so as to avoid excessive additives affecting the rotation of the arc plate 30.

[0053] After mixing is completed, the grouting material is discharged and then transported to the external shield machine for construction in waterless and boulder-like geology.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
