Technical Field
[0001] The invention relates to the technical field of vibratory impact equipment, and in particular to a vibratory impact device with a telescopic waist discharging function. Background Art
[0002] The vibrator is a special machine used in vibratory construction. It can generate horizontal vibration force to vibrate the filler and surrounding soil, thereby improving the bearing capacity of the foundation, reducing settlement, increasing foundation stability, and improving the ability to resist earthquake liquefaction.
[0003] The existing vibrator is connected to a material pipe, and the discharge port is a vibrating hole on the side wall of the material pipe, through which the crushed stone is discharged. However, in actual operation, the discharge end of the material pipe is a normally open material port. Once the crushed stone is loaded into the material pipe, the crushed stone will be directly discharged from the discharge port. In this way, when a problem occurs with the equipment, the output of the vibrating crushed stone cannot be temporarily stopped, and the machine can only be shut down after the crushed stone in the entire material pipe is completely transported, resulting in a large amount of time waste. Summary of the invention
[0004] The purpose of the present invention is to provide a vibratory impact device with a telescopic waist for discharging materials, which can temporarily stop the output of materials when a problem occurs in the device, thereby effectively saving waiting time.
[0005] In order to solve the above technical problems, the present invention adopts the following solutions: A vibratory impact device with a telescopic waist discharge comprises a crawler pile driver, a bracket of the crawler pile driver is provided with a vibratory impact device, the vibratory impact device comprises a feeding mechanism, a telescopic feed pipe and a vibrator from top to bottom, the feeding mechanism comprises a fixed hopper and a movable hopper, the fixed hopper is connected to the top of the bracket, the bottom of the fixed hopper is connected to the feed pipe, the movable hopper is connected to a winch on the crawler pile driver, the bottom of the feed pipe is connected to the vibrator, a discharge port located above the vibrator is provided on the side wall of the feed pipe, a plurality of discharge ports are provided and are evenly distributed around the feed pipe, a control component for controlling the opening or closing of the discharge port is slidably provided in the feed cavity inside the feed pipe, a cable and a water supply pipe which can follow the extension and retraction of the feed pipe are provided on the outer wall of the feed pipe, the cable is connected to a joint inside a junction box on the vibrator, and the water supply pipe is connected to a water pipeline inside the vibrator.
[0006] Due to the adoption of the above technical scheme, on the basis of the existing vibro-compaction equipment, the material pipe is changed into a telescopic material delivery pipe, so that the vibro-compaction device of the present application can vibrate out a deeper vibro-compaction hole, and then complete the construction of deeper vibro-compaction gravel piles, so that the foundation bearing capacity of the construction area is stronger; and the discharge port position of the original material pipe is a normally open material port. After the gravel enters the material pipe, as long as there is gravel inside the material pipe, the material port will continue to discharge material and cannot be stopped. In this way, when a problem occurs in the equipment or the feeding needs to be stopped at a certain stage in the vibro-compaction hole, it is impossible to temporarily stop the feeding, and the only thing to do is to wait until the gravel in the material pipe is completely emptied. In this way, when the machine needs to be shut down for maintenance, it is necessary to wait for a long time to clear the material, which results in too much gravel in the hole that is vibrated, resulting in the final gravel pile quality not meeting the standards, affecting the final project quality.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed", "opened", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example
[0022] A vibrating device with a telescopic waist discharge, such as Fig. 9 As shown, it includes a crawler pile driver 7, a vibrating device is installed on a bracket 8 of the crawler pile driver 7, and the vibrating device includes a feeding mechanism 1, a telescopic feeding pipe 2, and a vibrator 4 from top to bottom. The feeding mechanism 1 includes a fixed hopper 101 and a movable hopper 102. The fixed hopper 101 is connected to the top of the bracket 8, the bottom of the fixed hopper 101 is connected to the feeding pipe 2, the movable hopper 102 is connected to the winch on the crawler pile driver 7, and the bottom of the feeding pipe 2 is connected to the vibrator 4, a discharge port 3 located above the vibrator 4 is opened on the side wall of the feed pipe 2, and there are multiple discharge ports 3 evenly distributed around the feed pipe 2, a control component for controlling the opening or closing of the discharge port 3 is slidably arranged in the feed cavity 12 inside the feed pipe 2, and a cable 15 and a water supply pipe 5 that can follow the expansion and contraction of the feed pipe 2 are arranged on the outer wall of the feed pipe 2, the cable 15 is connected to the joint inside the junction box 6 on the vibrator 4, and the water supply pipe 5 is connected to the water pipeline inside the vibrator 4.
[0023] In the present embodiment, as shown in Figure 1, based on the existing vibro-compacting equipment, the material pipe is changed into a telescopic material delivery pipe 2, so that the vibro-compacting device of the present application can create a deeper vibro-compacting hole, and then complete the construction of a deeper vibro-compacted gravel pile, so that the foundation bearing capacity of the construction area is stronger; and the discharge port 3 of the original material pipe is a normally open material port. After the gravel enters the material pipe, as long as there is gravel inside the material pipe, the material port will continue to discharge material and cannot be stopped. In this way, when a problem occurs in the equipment or the feeding needs to be stopped at a certain stage in the vibro-compacting hole, it is impossible to temporarily stop the feeding, and the machine can only wait until the gravel in the material pipe is completely emptied. In this way, when the machine needs to be shut down for maintenance, it is necessary to wait for a long time to clear the material, which results in too much gravel in the hole that is vibro-compacted, resulting in the final gravel pile quality not meeting the standards, affecting the final project quality. In this scheme, on the ground, the crushed stone is first loaded into the movable hopper 102 by a loader, then lifted to the top of the bracket 8 by the winch equipment on the crawler crane, poured into the fixed hopper 101, and finally slid into the conveying pipe 2. Figure 7 and Figure 8 As shown, the present application is provided with a quantity control component on the inner side of the discharge port 3. During any time period of the vibro-conveyoring, if the machine needs to be shut down for maintenance or for other reasons that require stopping the feeding, the quantity control component can temporarily close the discharge port 3 and stop the continued output of the crushed stone. There is no need to wait for the crushed stone in the feeding pipe 2 to be completely emptied, thus saving time. At the same time, there will not be a large amount of uncompacted crushed stone in the hole due to the shutdown, thus ensuring that the final project quality meets the standards.
[0024] Furthermore, the fixed hopper 101 has a silo inside, a fixed rod 104 is provided above the silo, a connecting tube 103 connected to the silo is provided at the end of the fixed hopper 101, the lower end of the connecting tube 103 is connected to the feed pipe 2, the fixed rod 104 is circumferentially provided with a reinforcing plate 105 connected to the side wall of the silo (not shown in the figure), a first pulley 106 is provided on the top of the fixed rod 104, a support frame 107 is provided on the side wall of the fixed rod 104, a second pulley 108 is provided at the end of the support frame 107, a steel wire rope 109 is provided on the first pulley 106 and the second pulley 108, one end of the steel wire rope 109 is connected to a hoisting device, and the other end is connected to the movable hopper 102, the hoisting device (not shown in the figure) drives the steel wire rope 109 to drive the movable hopper 102 to rise and pour the gravel inside into the fixed hopper 101.
[0025] Specifically, Figure 2 and Figure 3As shown, the fixed hopper 101 is a cone shape, which is convenient for the crushed stone to slide quickly into the feeding pipe 2. The silo can prevent the movable hopper 102 from splashing when pouring the crushed stone into the fixed hopper 101. The connecting tube 103 is open at both ends and is detachably connected to the top of the feeding pipe 2 by bolts. The upper end of the connecting tube 103 is welded and fixed to the bottom of the fixed hopper 101. A fixing rod 104 is provided in the silo, and the lower end of the fixing rod 104 is suspended in the air, which can avoid affecting the sliding of the crushed stone. The reinforcing plate 105 can enhance the strength of the entire fixed hopper 101 and extend its service life. One end of the wire rope 109 is wound around the hoisting device on the crawler pile driver 7, and the other end cooperates with the second pulley 108. In this way, the movable hopper 102 is lifted by driving the wire rope 109 to be retracted and released by the hoisting device, thereby realizing feeding.
[0026] Furthermore, the cross-section of the movable hopper 102 is trapezoidal, and hangers 110 are movably connected on the two side walls of the movable hopper 102. A third pulley 114 is provided inside the hanger 110, and the wire rope 109 is movably connected to the third pulley 114. A limiting column 112 is also provided on the side wall of the movable hopper 102, and limiting bending portions 111 that cooperate with the limiting columns 112 are provided on both sides of the fixed hopper 101. After the hoisting device lifts the movable hopper 102 vertically until the limiting columns 112 contact the limiting bending portions 111, the hoisting device continues to lift the movable hopper 102, and the limiting bending portions 111 change the path of the movable hopper 102. The movable hopper 102 starts to rotate toward the silo with the limiting columns 112 as the axis, and the movable hopper 102 pours the gravel inside into the silo.
[0027] Specific feeding principle: Figure 1-3 As shown, before loading, the movable hopper 102 is located on the ground. After it is filled with crushed stone, the winch equipment is operated, and the hanger 110 is lifted by the wire rope 109 to drive the movable hopper 102 to the top position of the bracket 8, until the limit column 112 contacts the limit bending part 111, and the limit bending part 111 restricts the movable hopper 102 from continuing to rise, and the limit bending part 111 and the limit column 112 can rotate relative to each other after contact. The two ends of the hanger 110 are also rotatably connected to the side walls of the movable hopper 102. After the winch equipment continues to lift a small end of the movable hopper 102, the movable hopper 102 will rotate to the side of the fixed hopper 101 with the limit column 112 as the axis, and then the crushed stone in the movable hopper 102 is poured into the fixed hopper 101 to realize loading, and the cross-section of the movable hopper 102 is trapezoidal, which can accelerate the pouring of crushed stone into the fixed hopper 101.
[0028] Furthermore, a stabilizing frame 113 is fixed on the side wall of the movable hopper 102 , and the stabilizing frame 113 is located on one side of the inclined side wall of the movable hopper 102 , and the bottom surface of the stabilizing frame 113 is flush with the bottom surface of the movable hopper 102 .
[0029] Specifically, when on the ground, after the movable hopper 102 is filled with materials, since the cross-section of the movable hopper 102 is trapezoidal, after being filled with crushed stone, the center of gravity of the entire movable hopper 102 shifts to one side of the inclined surface, which can easily cause the movable hopper 102 to tip over. Therefore, door-shaped stabilizing frames 113 are welded on both sides of the movable hopper 102, and the stabilizing frames 113 are flush with the bottom surface of the movable hopper 102, supporting one side of the inclined surface of the movable hopper 102 to prevent the movable hopper 102 from tipping over.
[0030] Furthermore, the feed pipe 2 includes multiple sections of guide pipes that are slidably connected to each other, namely the first guide pipe 201, the second guide pipe 202, and the third guide pipe 203. The inner diameters of the three guide pipes gradually decrease from top to bottom. The first guide pipe 201 is bolted to the connecting tube 103, the upper end of the second guide pipe 202 is inserted into the first guide pipe 201, and the upper end of the third guide pipe 203 is inserted into the second guide pipe 202. There is a feed cavity 12 in the three guide pipes. The third guide pipe 203 is connected to the vibrator 4, and the discharge port 3 is opened on the side wall of the third guide pipe 203. The quantity control component is located inside the third guide pipe 203, and a clamping device for controlling the descending speed of the second guide pipe 202 and the third guide pipe 203 is provided on the side of the feed pipe 2.
[0031] Specifically, Figure 4 As shown, the first material guide pipe 201 is the material guide pipe on the uppermost layer, and its inner diameter is relatively large. It is fastened to the connecting tube 103 by bolts to ensure stability. The inner diameter of the second material guide pipe 202 is smaller than that of the first material guide pipe 201. Its upper end is inserted into and can slide freely in the first material guide pipe 201 to adapt to the length adjustment under different working requirements. The inner diameter of the third material guide pipe 203 is further reduced, and the upper end is inserted into the second material guide pipe 202 and can also slide. The adjacent material guide pipes will not fall off. After the gravel enters the material guide pipe, the clamping tightness of the corresponding material guide pipe by the clamping device is changed to control the extension and contraction speed of the feed pipe 2 to avoid the sudden drop of the material guide pipe. At the same time, the sliding speed of the material guide pipe should match the sliding speed of the cable 15 and the water supply pipe 5 to avoid the risk of the material guide pipe falling too fast and the speed difference between the cable 15 and the water supply pipe 5 causing the risk of breakage.
[0032] Furthermore, the clamping device includes a mounting seat 11 and a clamping portion 10 hinged to the mounting seat 11. The mounting seat 11 is provided with three and respectively corresponds to the first material guide tube 201, the second material guide tube 202, and the third material guide tube 203. The clamping portion 10 includes two symmetrically arranged clamping arms 14. The clamping arms 14 are arc-shaped, and the inner side of the clamping arms 14 has a clamping arc surface adapted to the corresponding material guide tube. A hydraulic cylinder 13 is hinged on the mounting seat 11, and the telescopic end of the hydraulic cylinder 13 is hinged to the clamping arm 14.
[0033] Specifically, Figure 4As shown, there are three mounting seats 11, corresponding to the first material guide tube 201, the second material guide tube 202, and the third material guide tube 203 respectively. Such a design ensures that each material guide tube can be clamped independently and stably. The mounting seat 11 serves as a support and fixing point for the clamping portion 10. The mounting seat 11 is firmly mounted at an appropriate position of the material delivery pipe 2 system so as to effectively clamp and control the material guide tube. The clamping portion 10 includes two symmetrically arranged clamping arms 14. The two clamping arms 14 together constitute a pliers-like structure for clamping the material guide tube. The clamping arm 14 is arc-shaped. Such a design enables the clamping arm 14 to fit tightly against the outer wall of the material guide tube and provide a stable clamping force. The inner side of the clamping arm 14 has a clamping arc surface adapted to the corresponding material guide tube, which further enhances the stability and reliability of the clamping and prevents the material guide tube from sliding or deflecting during the clamping process. After the clamping arm 14 is clamped on each material guide tube, it will not contact the water supply pipe 5 or the cable 15. The hydraulic cylinder 13 is hinged on the mounting seat 11. The hydraulic cylinder 13 can rotate around the hinge point to adjust its extension direction. The extension end of the hydraulic cylinder 13 is hinged with the clamping arm 14, so that when the hydraulic cylinder 13 is extended, the clamping arm 14 can be driven to open and close. Specifically, when the hydraulic cylinder 13 is extended, the clamping arm 14 will move closer to the center and clamp the material guide pipe; when the hydraulic cylinder 13 is shortened, the clamping arm 14 will open outward to release the material guide pipe. When it is necessary to adjust the descending speed of the material guide pipe, the operator can change the clamping force of the clamping part 10 on the material guide pipe by controlling the extension and contraction of the hydraulic cylinder 13. If you want to slow down the descent speed of the material guide tube, you can increase the extension of the hydraulic cylinder 13 so that the clamping arm 14 clamps the material guide tube more tightly, thereby increasing the friction and slowing down the descent speed; on the contrary, if you want to speed up the descent speed of the material guide tube, you can reduce the extension of the hydraulic cylinder 13 or shorten it so that the clamping force of the clamping arm 14 on the material guide tube is reduced, the friction is reduced, and the descent speed is accelerated. This clamping device achieves flexible adjustment of the descent speed of the material guide tube through precise control of the hydraulic cylinder 13, and its arc-shaped clamping arm 14 and the adapted clamping arc surface design ensure the stability and reliability of clamping.
[0034] Furthermore, a guide wheel 18 is provided on the bottom surface of the clamping arm 14 to press against the side wall of the material guiding tube.
[0035] Specifically, Figure 6As shown, the guide wheel 18 acts as a rolling contact element, forming rolling friction with the side wall of the guide tube. Compared with direct sliding friction, the resistance of rolling friction is smaller, which helps to reduce the wear of the clamping part 10 on the side wall of the guide tube and reduce energy consumption. The guide wheel 18 can ensure that the clamping arm 14 maintains stable contact when clamping the guide tube, avoiding shaking or jamming of the guide tube due to uneven clamping force or offset clamping position. When the guide tube needs to adjust its position or descending speed, the guide wheel 18 can also play an auxiliary guiding role, and can guide each guide tube to move along a predetermined path to ensure the continuity and stability of material transportation.
[0036] Furthermore, the quantity control component includes a plugging head 20, the bottom end of the third material guide tube 203 is a closed end, the plugging head 20 is slidably arranged in the material delivery cavity 12 of the third material guide tube 203 and is located below the discharge port 3, a sliding column 22 is provided at the bottom end of the plugging head 20, a sealing ring is embedded in the circumference of the sliding column 22, and a top pressure cavity 17 connected to the water supply pipe 5 is formed between the sliding column 22 and the bottom end of the third material guide tube 203, a three-way solenoid valve 19 is provided on the pipeline connecting the top pressure cavity 17 and the water supply pipe 5, and a pressure sensor 24 for sensing the water pressure in the top pressure cavity 17 is provided at the bottom of the third material guide tube 203.
[0037] Specifically, Figure 7 and Figure 8As shown, the plugging head 20 is a key component for controlling the material flow. The plugging head 20 slides in the feeding cavity 12 of the third material guide tube 203, and limits or allows the material to be discharged through the discharge port 3 by changing its vertical position. The plugging head 20 is located below the discharge port 3 to ensure that the discharge port 3 can be completely blocked when the plugging head 20 rises to prevent the material from being discharged, and the material is allowed to be discharged through the discharge port 3 when the plugging head 20 descends. The sliding column 22 is fixed at the bottom end of the plugging head 20 and slides in the third material guide tube 203 with the plugging head 20, and the sealing ring is embedded in The sliding column 22 is circumferentially sealed with the inner wall of the third material guide tube 203 to prevent water from leaking from the gap between the sliding column 22 and the third material guide tube 203. The top pressure chamber 17 is a space formed between the sliding column 22 and the bottom end of the third material guide tube 203. When water is injected into the top pressure chamber 17, the water pressure will act on the sliding column 22 to push the plugging head 20 up or down, thereby controlling the material flow rate. The top pressure chamber 17 is provided with a pressurized water source by means of the water supply pipe 5. The position of the plugging head 20 is controlled by adjusting the water flow and water pressure in the water supply pipe 5. A three-way solenoid valve 19 is provided on the connected pipeline to control the on-off relationship between the water supply pipe 5 and the top pressure chamber 17 and the flow direction of the water flow. The three-way solenoid valve 19 controls the on-off relationship between the water supply pipe 5 and the top pressure chamber 17 and adjusts the flow direction of the water flow as needed. By controlling the switch state of the three-way solenoid valve 19, the water pressure in the top pressure chamber 17 can be accurately adjusted. The pressure sensor 24 is installed at the bottom of the third guide pipe 203 to monitor the water pressure change in the top pressure chamber 17 in real time. The pressure sensor 24 converts the water pressure signal into an electrical signal and transmits it to the control system The control system calculates the output of crushed stone according to the feedback signal of the pressure sensor 24. When the plugging head 20 seals the discharge port 3 circumferentially, the water pressure is the weight of the crushed stone above. The pressure sensor 24 obtains an initial pressure value. When the crushed stone needs to be quantitatively output, the plugging head 20 opens the discharge port 3, and the discharge amount is certain. After opening for a period of time, the discharge port 3 is closed again. The pressure sensor 24 will obtain a new pressure value again. The initial pressure value is subtracted from the new pressure value to obtain the gravity value of the output crushed stone, which is then converted into the weight value of the crushed stone. Working principle: When it is necessary to reduce or stop the material flow, the control system controls the three-way solenoid valve 19 to inject water into the top pressure chamber 17 through the water supply pipe 5. The water pressure acts on the sliding column 22 to push the plugging head 20 up, gradually blocking the discharge port 3, thereby reducing the discharge amount of the material through the discharge port 3. When it is necessary to open or increase the material flow, the control system controls the three-way solenoid valve 19 to discharge the water in the top pressure chamber 17, the water pressure is reduced, and the plugging head 20 descends under the action of the material pressure or its own gravity, gradually opening the discharge port 3 to allow more material to pass through.
[0038] Furthermore, the length of the plugging head 20 is greater than the length of the discharge port 3, the upper end of the plugging head 20 is a conical surface, the lower end of the sliding column 22 is provided with a pad 23, and the inner wall of the third material guide tube 203 is provided with a limit block 21 located below the discharge port 3. When the plugging head 20 seals the discharge port 3, the top of the plugging head 20 is located above the upper end of the discharge port 3.
[0039] Specifically, Figure 7 As shown, the length of the plugging head 20 is greater than the discharge port 3, ensuring that when the plugging head 20 completely seals the discharge port 3, its length is sufficient to cover the entire range of the discharge port 3, thereby preventing the material from leaking from the edge of the discharge port 3. The design of the conical surface enables the plugging head 20 to more easily guide the flow of materials when approaching the discharge port 3 and reduce the friction with the edge of the discharge port 3. At the same time, when the plugging head 20 rises to seal the discharge port 3, the conical surface can gradually compress the material and force it to flow to other areas, thereby improving the sealing effect. The pad 23 can prevent the sliding column 22 from always having a certain gap with the third guide pipe 203, facilitating the injection of water. The inner wall of the third guide pipe 203 is provided with a limit block 21, which is located below the discharge port 3 and is used to limit the rising position of the plugging head 20 in the third guide pipe 203. When the plugging head 20 rises to a certain extent, it will encounter the obstruction of the limit block 21 and stop rising.
[0040] Furthermore, the first material guide tube 201, the second material guide tube 202 and the third material guide tube 203 are provided with positioning sleeves 9 adapted to the water supply pipe 5 and the cable 15, the water supply pipe 5 and the cable 15 respectively pass through two assembly openings 16 on the positioning sleeves 9, the water supply pipe 5, the cable 15 and the positioning sleeves 9 can slide relative to each other, the water supply pipe 5 and the cable 15 can be bent, and the connecting sleeves on the second material guide tube 202 and the third material guide tube 203 are both located near the bottom of the tube.
[0041] Specifically, Figure 5As shown, the positioning sleeve 9 is adapted to the water supply pipe 5 and the cable 15 to ensure that the water supply pipe 5 and the cable 15 can be installed in the positioning sleeve 9. The positioning sleeve 9 is provided with two assembly ports 16, which are used to pass the water supply pipe 5 and the cable 15 respectively. This design enables the water supply pipe 5 and the cable 15 to be installed on the guide pipe in parallel or separately without interfering with each other. The water supply pipe 5, the cable 15 and the positioning sleeve 9 can slide relative to each other. This feature allows the water supply pipe 5 and the cable 15 to move flexibly with the guide pipe when it moves or adjusts its position without being affected. The water supply pipe 5 and the cable 15 can be bent and wound to avoid large resistance or damage, which makes them more easily adaptable to the guide pipe system of different shapes and layouts. Whether it is a straight section or a curved section, the water supply pipe 5 and the cable 15 can maintain stable connection and transmission functions, and the water supply pipe 5 will not bend after bending, so as not to affect the water supply flow. The water supply pipe 5 and the cable 15 can be wound around the roller of the crawler pile driver 7, and then the motor drives the roller to realize the retraction and extension of the cable 15 and the water supply pipe 5. The retraction and extension speed matches the extension and contraction speed of the feed pipe 2. The connecting sleeves on the second guide pipe 202 and the third guide pipe 203 are both located near the bottom of the pipe, which can avoid the two guide pipes being affected by the connecting sleeves when they are recovered. Such a position allows the second guide pipe 202 and the third guide pipe 203 to be recovered to the shortest position. At the same time, the assembly port 16 can be provided with curling edges above and below to avoid damage to the cable 15 and the water supply pipe 5.
