Description

Technical Field

[0001] The invention relates to the technical field of foundation treatment devices, and in particular to an assembled foundation treatment device for a soft soil foundation. Background Art

[0002] Ground compaction is an indispensable part of the ground treatment process in construction projects. It aims to make the foundation soil layer denser by applying pressure to the ground, thereby increasing the bearing capacity and stability of the foundation. Impact compactors are widely used due to their high efficiency, flexibility, easy operation and simple maintenance. At the same time, the compaction blocks of impact compactors are usually assembled. When in use, they can be replaced by staff according to specific working conditions and construction requirements. It is also convenient for staff to maintain the compactors and compaction blocks later.

[0003] The existing impact compactor usually relies on a lifting device to lift the compacting block to a certain height and then release it, so that it falls freely and hits the ground to compact the foundation. Different areas of the same foundation will be divided into soft and hard areas. When using the impact compactor to compact the hard soil foundation part, it is necessary to increase the compaction frequency to overcome the initial resistance of the soil. When using the impact compactor to compact the soft soil foundation part, it is necessary to reduce the compaction frequency to avoid surface rupture or deep soil structure damage caused by rapid compaction. Therefore, before compacting the foundation, it is necessary to use the existing detection device to detect the hardness of the foundation. After the detection of a certain area is completed, the staff needs to make corresponding adjustments to the compaction frequency of the compactor according to the test results, and then start the compactor to start compaction operations. When the hardness of the foundation changes frequently, the above detection process needs to be repeated. At the same time, the compactor needs to be shut down during the detection to repeat the above process of adjusting the compactor. The overall process is cumbersome, which greatly affects the construction efficiency of foundation compaction and slows down the overall construction progress. Summary of the invention

DETAILED DESCRIPTION

[0055] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0056] Embodiment 1: A prefabricated foundation treatment device for soft soil foundation, such as Figure 1-Figure 6 As shown, it includes a mounting shell 1, one side of which is provided with a control terminal; a driving motor 2, which is mounted on the upper side of the mounting shell 1; a tamping block 3, which is slidably connected to the mounting shell 1, and the output shaft of the driving motor 2 and the tamping block 3 are jointly provided with a connecting module; a liquid storage shell 4, which is fixed to the inside of the mounting shell 1; a shaped piece 5, which is slidably connected to the inside of the liquid storage shell 4; a pressure detector 7, which is mounted inside the liquid storage shell 4, and a first spring is provided between the pressure detector 7 and the shaped piece 5, and the pressure detector 7 is used to detect the extrusion force exerted on the first spring; a moving block 8, which is limitedly slidably connected to the lower side of the tamping block 3, and the moving block 8 is extruded and matched with the soil; a transmission assembly, which is arranged in the mounting shell 1, and the transmission assembly is used to transmit the extrusion force exerted on the moving block 8 to the shaped piece 5.

[0057] In the above scheme, it is intended to solve the problem that in the process of compacting soft soil ground by existing compacting machines, it is necessary to use existing devices to detect the softness and hardness of the foundation in advance before changing the compacting frequency of the compacting machine; a pressure roller is arranged on the left part of the lower side of the mounting shell 1, which is used to preliminarily compact the ground and facilitate the movement of the entire device; a control terminal is installed on the upper side of the mounting shell 1, and the control terminal is electrically connected to the drive motor 2; the compacting block 3 is located on the left side of the mounting shell 1; the connecting module is an existing device, which can be selected as a crank rocker mechanism or other mechanical structure that can drive the compacting block 3 to move up and down when in use; the first spring is used to drive the I-shaped member 5 to reset; the pressure detector 7 is electrically connected to the control terminal, and the pressure detector 7 detects the pressure on the first spring, and then detects the softness of the soil; the moving block 8 is located on the left part of the lower side of the compacting block 3, and when in use, the moving block 8 moves upward due to the squeezing force of the soil.

[0058] Furthermore, the transmission assembly includes: an extrusion plate 10, which is slidably connected to the tamping block 3, a second spring is fixedly connected between the tamping block 3 and the extrusion plate 10, a liquid storage chamber 9 is provided in the tamping block 3, the liquid storage chamber 9 is connected to the liquid storage shell 4 through a connecting pipe, and the extrusion plate 10 slides in the liquid storage chamber 9; an extrusion column 12, which is fixedly connected to the lower side of the extrusion plate 10, the extrusion column 12 passes through the tamping block 3 and is extruded and matched with the moving block 8; a limit block 13, which is slidably connected to the tamping block 3, a third spring is fixedly connected between the limit block 13 and the tamping block 3, and the moving block 8 is provided with a limit hole that is limited and matched with the limit block 13; a locking assembly, which is arranged on the mounting shell 1, and the locking assembly is used to limit the position of the I-shaped part 5.

[0059] In the above scheme, the transmission assembly is used to transmit the extrusion force exerted on the moving block 8 to the workpiece 5; the liquid storage chamber 9 is filled with hydraulic oil, and the volume of the hydraulic oil in the liquid storage chamber 9 is changed by the position of the extrusion plate 10; the second spring is used to drive the extrusion plate 10 to reset; the extrusion force exerted on the moving block 8 is transmitted to the extrusion plate 10 by the extrusion column 12; the third spring squeezes the limit block 13, so that the limit block 13 limits the moving block 8, that is, when the extrusion force exerted on the moving block 8 is greater than the elastic force of the third spring, the moving block 8 can continue to move upward.

[0060] Furthermore, under the action of the squeezing force of the third spring, the friction force between the limiting block 13 and the moving block 8 is smaller than the gravity of the moving block 8 .

[0061] In the above solution, it is ensured that the third spring and the limiting block 13 can provide a limiting effect on the moving block 8 under the cooperation, and the moving block 8 can also be smoothly reset downward to the initial position.

[0062] Furthermore, the limit block 13 is provided with symmetrically distributed inclined surfaces, and the height of the projection of the inclined surfaces on the limit block 13 on the vertical plane is equal to the distance between the extrusion column 12 and the moving block 8 .

[0063] In the above scheme, the shape of the limit block 13 is limited, and the extrusion column 12 is not in contact with the moving block 8 initially. When the moving block 8 moves upward and loses the limit cooperation with the limit block 13, the moving block 8 contacts the extrusion column 12, thereby reducing the frequency of the upward movement of the extrusion column 12 and preventing the extrusion column 12 and subsequent parts from being aggravated by frequent movement. Wear, affecting the normal use of subsequent parts.

[0064] The working principle of the above scheme is as follows: after the staff moves the device to the ground that needs to be compacted, the control terminal is started and the locking assembly is controlled to work so that the locking assembly releases the limit on the work-shaped member 5. Then the control terminal starts the drive motor 2. During the rotation of the output shaft of the drive motor 2, the compacting block 3 moves downward until the compacting block 3 moves downward to contact the ground. The ground is compacted by the gravity of the compacting block 3 itself. At the same time, during the compaction process, the ground reacts to the moving block 8, so that the moving block 8 moves upward due to the reaction force of the ground.

[0065] During the upward movement of the moving block 8, the moving block 8 squeezes the inclined surface on the lower side of the limit block 13, causing the limit block 13 to move and compressing the third spring to accumulate force until the moving block 8 moves upward to lose contact with the inclined surface of the limit block 13, and the moving block 8 contacts the extrusion column 12. Subsequently, during the continued upward movement of the moving block 8, the moving block 8 pushes the extrusion column 12 to move, and the extrusion column 12 drives the extrusion plate 10 to move upward synchronously, while compressing the second spring to accumulate force until the moving block 8 moves upward to a position where it loses contact with the limit block 13, and the limit block 13 is reset to its initial position under the action of the third spring.

[0066] During the upward movement of the extrusion plate 10, the greater the distance the extrusion plate 10 moves upward, the softer the soil is. The extrusion plate 10 transports the hydraulic oil in the liquid storage chamber 9 to the liquid storage shell 4, so that the I-shaped piece 5 moves upward under the extrusion force, and the first spring is compressed and stored. At the same time, the value detected by the pressure detector 7 continues to increase. When the compacting block 3 stops moving downward, the value detected by the pressure detector 7 stops increasing synchronously. Then, the control terminal reduces the speed of the output shaft of the drive motor 2 according to the value detected on the pressure detector 7, that is, reduces the frequency of the compacting block 3 moving downward, thereby reducing the frequency of compacting the foundation. There is no need to stop the machine, so that the compacting block 3 can work continuously, which improves the efficiency of compacting the foundation. At the same time, the soil after each compaction has enough time to rearrange and stabilize, thereby ensuring uniform compaction of the soil and avoiding excessive compression of the soil due to high-frequency compaction in the process of compacting the soft soil surface, resulting in excessive soil density that is not conducive to subsequent engineering operations.

[0067] After the tamping block 3 stops moving downward, the output shaft of the driving motor 2 drives the tamping block 3 to reset upward through the connecting module. During this process, when the moving block 8 moves upward until it loses contact with the ground, the squeezing plate 10 and the moving block 8 begin to reset downward under the combined action of their own gravity and the second spring. During the downward movement of the squeezing plate 10, the hydraulic oil squeezed into the liquid storage shell 4 is pumped back into the liquid storage chamber 9, so that the I-shaped piece 5 is reset downward to the initial position. During the downward movement of the moving block 8, the moving block 8 pushes out the soil remaining in the tamping block 3 until the moving block 8 is reset downward to the position aligned with the limit block 13. When in contact, the moving block 8 squeezes the inclined surface on the upper side of the limit block 13, causing the limit block 13 to move forward again, and causing the third spring to compress and accumulate force again, until the moving block 8 is reset to the initial position. The limit block 13 is reset to the initial position under the action of the third spring, that is, the limit block 13 limits the moving block 8 again, and then controls the locking assembly to limit the I-shaped piece 5 again. In the subsequent process of compacting the foundation, the staff intermittently controls the locking assembly to work, so that the I-shaped piece 5 moves intermittently, and then intermittently adjusts the frequency of compacting the ground by the compacting block 3. After the compaction of the ground is completed, the staff shuts down the control terminal.

[0068] Further, such as Figure 4 , Figure 7 and Figure 8 As shown, the locking assembly includes: a limit plate 15, which is slidably connected to one side of the mounting shell 1, a fourth spring is arranged between the limit plate 15 and the mounting shell 1, and the limit plate 15 is slidably connected to the liquid storage shell 4, and the limit plate 15 is limitedly matched with the I-shaped member 5; a limit groove 16, which is arranged on the upper side of the limit plate 15; a connecting rod 17, which is rotatably connected to the right side of the liquid storage shell 4, and a torsion spring is fixedly connected between the connecting rod 17 and the liquid storage shell 4; a limit rod 18, which is slidably connected to the right end of the connecting rod 17, a tension spring is fixedly connected between the limit rod 18 and the connecting rod 17, and the limit rod 18 slides in the limit groove 16.

[0069] In the above scheme, an inclined surface is provided on the left side of the limit plate 15, and the distance between the inclined surface and the I-shaped piece 5 gradually increases from left to right. Initially, the lower side of the limit plate 15 contacts the upper side of the I-shaped piece 5. During the resetting process of the I-shaped piece 5, the I-shaped piece 5 squeezes the inclined surface on the left side of the limit plate 15; the angle between the inclined surface on the left side of the limit plate 15 and the horizontal plane is not less than 45°, ensuring that the I-shaped piece 5 can be smoothly reset downward; the projection of the limit groove 16 on the horizontal plane is heart-shaped, and initially the limit rod 18 is located in the depression on its right side, and the fourth spring is in a compressed state, but has not been compressed to the limit state.

[0070] Furthermore, the bottom surface of the limiting groove 16 is composed of four parts, namely, a first limiting portion 161 , a second limiting portion 162 , a third limiting portion 163 and a fourth limiting portion 164 , which are connected in pairs, and each part is provided with an inclined surface.

[0071] In the above scheme, the shape of the bottom surface of the limiting groove 16 is limited so that Figure 8 The viewing angle is taken as the reference viewing angle, and the four limiting parts are distributed counterclockwise on the limiting plate 15, so that when the limiting rod 18 moves in the limiting groove 16, it moves counterclockwise along the limiting groove 16.

[0072] Furthermore, the maximum height difference and the minimum height difference between the inclined surfaces of the first limiting portion 161 , the second limiting portion 162 , the third limiting portion 163 and the fourth limiting portion 164 and the connecting rod 17 are equal.

[0073] In the above solution, when the limiting rod 18 moves in the limiting groove 16 , when the limiting rod 18 contacts the uppermost side of the four limiting positions, the limiting rod 18 moves upward to the limit position.

[0074] The working principle of the above scheme is as follows: in the process of the above-mentioned staff controlling the locking assembly to release the limit on the I-shaped member 5, the staff presses the limit plate 15 to move the limit plate 15 to the left and compress the fourth spring again. In the process of the limit plate 15 moving to the left, the limit groove 16 squeezes the limit rod 18, so that the limit rod 18 moves along the third limit portion 163, and the limit rod 18 drives the connecting rod 17 to rotate around the connection between the connecting rod 17 and the liquid storage shell 4, so that the torsion spring between the connecting rod 17 and the liquid storage shell 4 is twisted and force is accumulated. At the same time, the limit rod 18 is squeezed by the inclined surface on the third limit portion 163 and moves upward, and the tension spring between the limit rod 18 and the connecting rod 17 is stretched and force is accumulated. In this process, the limit rod 18 gradually moves upward to the limit position. When the limit rod 18 moves upward to the limit position, the limit rod 18 is still in contact with the third limit portion 163.

[0075] Until the limit plate 15 moves to the left to the extreme position, the limit rod 18 moves past the junction of the third limit portion 163 and the fourth limit portion 164. At this time, the limit rod 18 is located on the fourth limit portion 164. At the same time, the limit rod 18 is reset to the initial height under the action of the adjacent tension spring. Then the staff releases the limit plate 15. At this time, the limit plate 15 is reset to the right driven by the fourth spring. At the same time, the limit rod 18 moves along the fourth limit portion 164 due to the extrusion force of the limit groove 16. The specific movement process of the limit rod 18 The process will not be described in detail, and reference will be made to the above. After the limit plate 15 moves to the right to the extreme position, the fourth spring is in an uncompressed state, and the limit rod 18 passes through the junction of the fourth limit portion 164 and the first limit portion 161. At the same time, the limit rod 18 is located on the first limit portion 161. At this time, the limit plate 15 loses contact with the I-shaped member 5, so that the I-shaped member 5 can move upward under the squeeze of the hydraulic oil, thereby compressing the first spring and accumulating force, and the value detected by the pressure detector 7 gradually increases.

[0076] After the above-mentioned I-shaped piece 5 is reset, that is, after the tamping block 3 completes one tamping, the staff presses the limit plate 15 again to make the limit plate 15 limit the I-shaped piece 5 again. During this process, the limit rod 18 moves along the first limit portion 161 until the limit plate 15 moves to the left to the extreme position again, the limit rod 18 passes through the junction of the first limit portion 161 and the second limit portion 162, and the limit rod 18 is located on the second limit portion 162. The staff releases the limit plate 15. At this time, the limit plate 15 is reset to the initial position under the action of the fourth spring, and then the limit rod 18 moves along the second limit portion 162. After the limit plate 15 is reset to the initial position, the limit rod 18 passes through the junction of the second limit portion 162 and the third limit portion 163, and the limit rod 18 is located on the third limit portion 163. The specific movement process of the limit rod 18 can be referred to above and will not be described in detail.

[0077] In the subsequent process of compacting the ground, the staff intermittently presses the limit plate 15 according to the compacted position, and then intermittently adjusts the rotation speed of the output shaft of the drive motor 2.

[0078] Furthermore, if Figure 2 and Figure 9-11 As shown, it also includes an adjustment mechanism, which is arranged on the mounting shell 1. The adjustment mechanism is used to change the rising height of the tamping block 3. The adjustment mechanism includes: a connecting shaft 19, which is rotatably connected to the upper side of the mounting shell 1. The connecting shaft 19 is spline-connected to the output shaft of the driving motor 2. A slide groove is arranged on the left side of the connecting shaft 19. An active arm 20 is slidably connected in the slide groove of the connecting shaft 19. Initially, the active arm 20 is located on the upper side of the connecting shaft 19. The connecting shaft 19 is externally connected to a hydraulic pump, and the hydraulic pump is electrically connected to the control terminal; a rotating shaft 21, which is rotatably connected to the active arm 20 located on the connecting shaft 19 outside; driven arm 22, rotatably connected to the rotating shaft 21, and rotatably connected to the tamping block 3; electric push rod 23, electric push rod 23 is electrically connected to the control terminal, and is arranged inside the mounting shell 1, and a telescopic frame is installed between the electric push rod 23 and the mounting shell 1; connecting sleeve 24, slidably connected to the telescopic end of the electric push rod 23, and a fifth spring is arranged between the connecting sleeve 24 and the telescopic end of the electric push rod 23, a pressure sensor is installed in the connecting sleeve 24, and the pressure sensor is electrically connected to the control terminal; cleaning block 25, fixed to the left side of the connecting sleeve 24.

[0079] In the above scheme, the connecting shaft 19 is located at the left part of the upper side of the mounting shell 1, and a slide groove is arranged on the left side of the connecting shaft 19. The slide groove of the connecting shaft 19 is filled with hydraulic oil. The hydraulic pump is an existing device and is not shown in the figure. Initially, the active arm 20 is located on the upper side of the connecting shaft 19, and the active arm 20 is not completely located in the slide groove of the connecting shaft 19. The driven arm 22 is a telescopic arm, which is rotatably connected to the upper side of the tamping block 3. When the tamping block 3 is located on the upper side, the driven arm 22 is in an extended state, and the driven arm 22 is perpendicular to the tamping block 3. The telescopic frame is an existing device, and its specific working process is no longer described in detail. The vertical position of the electric push rod 23 can be adjusted by the telescopic frame. The electric push rod 23 is electrically connected to the control terminal, and the pressure sensor is used to detect the pressure exerted on the fifth spring, and then detect the resistance exerted on the cleaning block 25.

[0080] In this embodiment, the connection module in the above embodiment is replaced by an adjustment mechanism.

[0081] The above scheme aims to solve the problem that the existing compaction machine cannot autonomously adjust the compaction force according to the viscosity of the soft soil foundation. In the process of compacting the soft soil foundation, if the viscosity of the soft soil foundation is large, this part of the foundation has high plasticity and low strength, and is easy to deform under the action of external force. At this time, if the compaction force is too large, it will not only fail to effectively improve the bearing capacity of the soil, but also destroy the particle structure of the soil, resulting in the stability of the foundation being affected. The specific work flow is as follows:

[0082] After the control terminal starts the drive motor 2, the output shaft of the drive motor 2 drives the connecting shaft 19 to rotate, and the connecting shaft 19 drives the active arm 20 to rotate synchronously clockwise to Figure 1 The perspective from left to right is the reference perspective. During this process, the active arm 20 drives the driven arm 22 to rotate synchronously through the rotating shaft 21, and drives the tamping block 3 to gradually move downward. At the same time, the driven arm 22 also rotates relative to the tamping block 3 until the active arm 20 rotates 90°, and the rotating shaft 21 moves to the front side. At this time, the driven arm 22 also rotates to the maximum angle relative to the tamping block 3. Then, as the connecting shaft 19 continues to rotate, the connecting shaft 19 drives the active arm 20 to rotate from front to bottom. During this process, the driven arm 22 gradually rotates from an inclined state to a state perpendicular to the tamping block 3. After the active arm 20 rotates to the lower side, the driven arm 22 rotates synchronously to the lower side. At this time, the driven arm 22 is located at a position perpendicular to the tamping block 3, and the tamping block 3 stops moving downward.

[0083] During the downward movement of the tamping block 3, if the tamping block 3 contacts the ground, the tamping block 3 tamps the ground. At the same time, the tamping block 3 is blocked by the ground and cannot continue to move downward. At this time, the telescopic part of the slave arm 22 gradually moves toward its fixed part until the active arm 20 rotates to the lower side. The telescopic part of the slave arm 22 stops moving synchronously. Subsequently, while the output shaft of the driving motor 2 continues to rotate, the output shaft of the driving motor 2 drives the active arm 20 to rotate from bottom to back through the connecting shaft 19, and then lifts the rotating shaft 21 upward. At this time, the rotating shaft 21 pulls the telescopic part of the slave arm 22 out of its fixed part and the slave arm 22 also rotates backward relative to the tamping block 3 until the slave arm 22 is stretched to the limit length. The rotating shaft 21 drives the slave arm 22 to move synchronously, and the slave arm 22 drives the tamping block 3 to move upward synchronously until the active arm 20 rotates to the upper side, completing a tamping of the ground.

[0084] After the tamping block 3 completes one tamping and resets upward to the initial position, the control terminal starts the electric push rod 23, and the telescopic end of the electric push rod 23 drives the cleaning block 25 to move to the left through the connecting sleeve 24, and the cleaning block 25 cleans the soil attached to the bottom surface of the tamping block 3 to prevent the soil attached to the tamping block 3 from affecting the subsequent tamping process. During this process, the soil attached to the bottom surface of the tamping block 3 reacts on the cleaning block 25, so that the cleaning block 25 is affected by the resistance of the soil and drives the connecting sleeve 24 to move to the right relative to the telescopic end of the electric push rod 23, and compresses the fifth spring to accumulate force, while the value detected by the pressure sensor continues to increase.

[0085] Until the telescopic end of the electric push rod 23 moves to the left to the extreme position, the cleaning block 25 completes the cleaning of the soil on the tamping block 3, and then the control terminal controls the electric push rod 23 to reset to the initial state. At the same time, the control terminal judges the viscosity of the soil through the maximum value detected by the pressure sensor during a single cleaning process. When the value detected by the pressure sensor increases to a certain value, the control terminal starts the hydraulic pump, and the hydraulic pump draws out the hydraulic oil in the slide groove of the connecting shaft 19, thereby moving the active arm 20 downward. At the same time, the active arm 20 drives the tamping block 3 to move downward synchronously through the transmission of the rotating shaft 21 and the driven arm 22, so as to change the vertical position of the tamping block 3, reduce the gravitational potential energy of the tamping block 3 during the downward movement, and reduce the impact force of the tamping block 3 on the ground, thereby adjusting the tamping strength of the ground, ensuring the tamping effect of the soft soil foundation, and improving the stability and bearing capacity of the foundation.

[0086] During the above process of adjusting the position of the active arm 20, the control terminal synchronously adjusts the vertical position of the electric push rod 23 through the telescopic frame, so that the cleaning block 25 is always in contact with the lower side of the tamping block 3, ensuring the cleaning effect of the cleaning block 25 on the lower side of the tamping block 3. After the position adjustment of the tamping block 3 is completed, continue to compact the remaining ground according to the above operation until the ground in the designated area is compacted. The staff shuts down the above parts and maintains the parts on the device for subsequent use.

[0087] Furthermore, the adjustment mechanism also includes: a missing gear 26, which is rotatably connected to the interior of the mounting shell 1, and a plurality of teeth are fixedly connected to the missing gear 26, and a heavy ball is fixedly connected to the lower side of the missing gear 26, and the heavy ball always points to the center of the earth during use; a liquid storage tube 27, which is fixedly connected to the interior of the mounting shell 1, and the interior of the liquid storage tube 27 is filled with hydraulic oil; a moving rod 28, which is slidably connected to the liquid storage tube 27, and a displacement detector is arranged inside the liquid storage tube 27, and the displacement detector is electrically connected to the control terminal, and the displacement detector is used to detect the distance moved by the moving rod 28. Initially, the moving rod 28 can move left and right in the liquid storage tube 27, and the moving rod 28 is fixedly connected to a push plate 281 that slides in the liquid storage tube 27, and a limiting flow hole 29 is arranged on the push plate 281. The specific number of the limiting flow holes 29 can be selected by the staff according to actual needs. The left end of the moving rod 28 is fixedly connected to a rack meshing with the missing gear 26, and the missing gear 26 drives the moving rod 28 to move left and right.

[0088] Furthermore, the diameter of the flow limiting hole 29 gradually increases from both sides to the middle, so as to reduce the moving speed of the push plate 281, thereby reducing the influence of mechanical vibration on the position of the push plate 281 during use.

[0089] In the process of compacting the slope foundation, since the slope surface will cause the compactor to tilt as a whole, the magnitude of the force exerted by the compaction block 3 on the ground at this time is the component force of its gravity, which leads to low efficiency of the compaction block 3 when compacting the slope surface. To solve this problem, the present invention provides the following solution:

[0090] When the device moves toward the slope foundation, the angle between the mounting shell 1 and the horizontal plane gradually increases. During this process, the missing gear 26 and the mounting shell 1 rotate relative to each other, so that the missing gear 26 drives the moving rod 28 to move horizontally through the meshing of the teeth on the gear 26 and the rack on the moving rod 28. The moving rod 28 drives the push plate 281 to move synchronously, and at the same time, the hydraulic oil in the liquid storage tube 27 flows through the flow limiting hole 29, and the value detected by the displacement detector increases continuously. Until the mounting shell 1 is completely located on the slope, the mounting shell 1 is no longer tilted, and the moving rod 28 moves to the limit position. At this time, the value detected by the displacement detector no longer increases. Subsequently, the control terminal controls the hydraulic pump to deliver hydraulic oil to the slide groove of the connecting shaft 19 through the value detected by the displacement detector, so that the height of the active arm 20 is increased. The specific process of the active arm 20 moving upward is opposite to the specific process of the above-mentioned downward movement, which will not be described in detail. The gravitational potential energy of the tamping block 3 is increased, thereby generating greater kinetic energy and impact force when falling, so that the tamping strength of the tamping block 3 will not be reduced due to tilting, and the tamping efficiency of the tamping block 3 on the slope is the same as its tamping efficiency on the plane.

[0091] The above description is only an embodiment of the present invention and is not intended to limit the present invention. Any equivalent substitution made within the principle of the present invention should be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the existing technology known to the technicians in this professional field.
