Description

Technical Field

[0001] The present invention belongs to the technical field of slope trimming, and specifically relates to a slope trimming device for high-fill embankments in water conservancy construction. Background Art

[0002] A high-fill embankment refers to a roadbed where, in paddy fields or areas with perennial waterlogging, a fine-grained fill is used to build an embankment with a height greater than 6 m, and in other areas, the total fill height exceeds 18.0 m (for soil) or 20.0 m (for rock), which is called a high embankment. A high-fill embankment is a roadbed form with relatively high technical difficulty in traffic engineering, and its successful implementation depends on strict foundation treatment, scientific filling technology, a perfect drainage system, and dynamic monitoring and control. During the construction of a high-fill embankment, it is necessary to process its slope. The conventional slope presents a trapezoid between the slope and the road surface.

[0003] In order to ensure that the plane of the slope is relatively flat, it is usually necessary to trim the slope. At this time, a special trimming device will be used, which is mainly composed of a tamping and trimming device. A tamping column that reciprocates up and down is used to apply pressure to the plane of the slope. In order to increase the pressure, sand is usually filled inside the tamping column. However, since the slope usually has a certain slope, when tamping, the sand inside the tamping column will tilt to a certain extent, and since the tamping column is a closed environment, the center of gravity of the entire tamping column will shift to a certain extent, which will affect the pressurizing effect and it is difficult to achieve stable pressurization.

[0004] At the same time, during the slope trimming process, some slopes will bulge. It is difficult to flatten them by the hammering pressure of the tamping column and subsequent treatment is required. At the same time, some slopes will also show depressions, and sand needs to be manually filled during trimming, resulting in a relatively low overall trimming efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a slope trimming device for high-fill embankments in water conservancy construction to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A high-fill embankment slope trimming device for water conservancy construction, including a frame. On the left and right sides of the top of the frame, longitudinal guide rails are fixedly installed. Above the frame, there is a hoisting member. The left and right sides of the bottom end of the hoisting member are connected to the top ends of the longitudinal guide rails. In the middle of the bottom end of the hoisting member, a double-shaft motor is installed. The left and right ends of the double-shaft motor are connected to power components. The front and back sides of the power components are movably clamped with the longitudinal guide rails. At the bottom end of the power components, a tamping and trimming component is installed. The tamping and trimming component reciprocates up and down relative to the longitudinal guide rails through the power components. On one side of the tamping and trimming component, there is an overflow tank. The top end of the overflow tank is fixedly communicated with an overflow pipe. The other end of the overflow pipe is communicated with the tamping and trimming component. In the middle of the bottom end of the overflow tank, a three-way valve is fixedly communicated. On the other side of the frame, a transverse guide rail is fixedly installed. The front and back sides of the bottom end of the transverse guide rail are movably clamped with auxiliary leveling components. The top ends of the auxiliary leveling components are connected to the bottom end of the overflow tank. The front and back ends of the three-way valve are communicated with the tamping and trimming component.

[0007] Before trimming the slope, the external frame can be connected through the hoisting member, and the inclination angle of the device can be adjusted to ensure that the bottom end of the tamping and trimming component is perpendicular to the slope. At the same time, an external traction device is used to drive the device to move up and down relative to the slope to complete the traction process. At the same time, according to the required tamping pressure of the slope, the sand content inside the tamping and trimming component needs to be adjusted to meet the tamping and trimming requirements.

[0008] As a further technical solution of the present invention, the power component includes a guide frame. The front and back ends of the guide frame are movably clamped with the two longitudinal guide rails. The guide frame moves up and down relative to the longitudinal guide rails. On the left and right sides of the top end of the guide frame, extension seats are fixedly installed.

[0009] As a further technical solution of the present invention, one end of the extension seat away from the guide frame is movably connected to a first connecting rod through a rotating shaft. The end of the first connecting rod away from the extension seat is movably connected to a second connecting rod through a rotating shaft. One end of the second connecting rod is connected to the output end of the double-shaft motor.

[0010] When the tamping and trimming component is perpendicular to the slope, the preparation before slope tamping and trimming can be maintained. At this time, the double-shaft motor can be started to drive the second connecting rod to rotate. At this time, the corresponding first connecting rod will swing accordingly, and apply an upward pulling force and a downward pushing force to the extension seat, and drive the guide frame to reciprocate up and down, so as to synchronously drive the tamping and trimming component and the overflow tank at the bottom end to reciprocate up and down.

[0011] As a further technical solution of the present invention, the ramming and trimming assembly includes a pressure tank. The middle of the top end of the pressure tank is connected to the bottom end of the guide frame. The inside of the pressure tank is filled with sand. The top end of the pressure tank near one side of the overflow tank is fixedly communicated with an overflow port, and the overflow port is communicated with an overflow pipe.

[0012] As a further technical solution of the present invention, a locking ring frame is fixedly sleeved on the outer side of the pressure tank near the bottom end. Feeding valves are installed at both the front and rear ends of the locking ring frame. The top ends of the feeding valves are fixedly communicated with feeding hoses, and the other ends of the feeding hoses are communicated with a three-way valve.

[0013] When the pressure tank reciprocates up and down under the action of the guide frame, the slope at the specified position can be rammed by the cooperation of the pressure tank and the sand inside. At the same time, since the device is parallel to the slope before ramming, the sand inside the pressure tank can be inclined at this time. The inclined sand can overflow through the overflow port and enter the inside of the overflow tank through the overflow pipe for temporary storage. At this time, the inclined part of the sand inside the pressure tank can be exported, and the center of gravity of the pressure tank is adjusted. At this time, the reciprocating displacement of the pressure tank can apply a suitable pressure to the slope to complete the uniform pressure application process.

[0014] By arranging an overflow tank on one side of the ramming and trimming assembly and through the cooperation between the ramming and trimming assembly and the overflow tank, when the ramming and trimming assembly is inclined, the sand in the inclined state can be automatically exported and enter the inside of the overflow tank for temporary storage. At the same time, the amount of exported sand is positively correlated with the inclination angle, which can ensure the automatic adjustment of the center of gravity of the pressure tank when it is inclined. The entire adjustment process does not need to be manually completed, which can ensure that a uniform pressure is maintained during the inclined ramming and trimming, and improve the ramming quality.

[0015] When the slope at one position is rammed, the device can be towed along the slope downward by an external towing device. When there is a depression at the specified ramming position, the feeding mechanism inside the overflow tank can be opened, and the sand temporarily stored inside the overflow tank is input into the three-way valve. At the same time, the valves at both the left and right ends of the three-way valve are opened, and the sand then enters the feeding valve through the three-way valve and the feeding hose. By opening the feeding valve, the sand can be injected into the depression to complete the automatic filling of the slope depression and complete the self-trimming process.

[0016] By utilizing the sand overflowed when the device is inclined and the cooperation between the ramming and trimming assembly and the overflow tank, when the device reaches the depression of the slope, the sand can be exported and the depression can be self-filled. Through the self-filling of the device, the automatic trimming of the depression of the slope is realized. The entire trimming process can be completed synchronously with the ramming process, that is, ramming can be completed while trimming, avoiding subsequent filling operations and further improving the trimming efficiency.

[0017] As a further technical solution of the present invention, the auxiliary flattening assembly includes a first fixed seat, and the top end of the first fixed seat is connected to the positions near the four corners of the bottom end of the overflow tank. One end of the first fixed seat away from the overflow tank is movably connected to a support rod through a rotating shaft.

[0018] As a further technical solution of the present invention, one end of the support rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft. A guide block is installed at the bottom end of the second fixed seat, and the guide block is movably clamped with the transverse guide rail.

[0019] As a further technical solution of the present invention, a flattening plate is fixedly installed at the bottom end of the guide block. The bottom end of the flattening plate is always in contact with the surface of the slope. The flattening plate moves relatively closer or farther away under the drive of the support rod.

[0020] When the pressure tank realizes the tamping and trimming of the slope through reciprocating up and down displacement, the overflow tank can be synchronously driven to reciprocate up and down. At this time, the support rod can be synchronously driven to deflect, and a thrust and a pull force are applied to the guide block at the bottom end. At this time, the guide block can drive the flattening plate at the bottom end to reciprocate left and right under the guiding action of the transverse guide rail, that is, to keep relatively closer or relatively farther away. When the two flattening plates keep relative movement, the slope soil at the bottom end can be flattened, and the process of flattening the excess sand on the slope is completed.

[0021] By utilizing the tamping process of the device, that is, by using the reciprocating up and down displacement of the tamping and trimming assembly, and by using the cooperation between the tamping and trimming assembly, the overflow tank and the auxiliary flattening assembly, the relative displacement of the two flattening plates is realized. While the slope is tamped and trimmed, the convex part of the slope can be trimmed and flattened. The whole process can be completed synchronously, and tamping and convex trimming can be completed at the same time, significantly improving the overall trimming efficiency.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) In the present invention, an overflow tank is arranged on one side of the tamping and trimming assembly. Through the cooperation between the tamping and trimming assembly and the overflow tank, when the tamping and trimming assembly is tilted, the sand in the tilted state can be automatically exported and enter the interior of the overflow tank for temporary storage. At the same time, the amount of exported sand is positively correlated with the tilt angle, which can ensure the automatic adjustment of the center of gravity of the pressure tank during tilting. The whole adjustment process does not need to be manually completed, which can ensure uniform pressure during tilting tamping and trimming and improve the quality of tamping.

[0024] (2) By utilizing the sand that overflows when the device is tilted and the cooperation between the ramming and trimming component and the overflow tank, when the device reaches the concave part of the slope, the sand can be exported to self-fill the concave part. Through the self-filling of the device, the automatic trimming of the concave part of the slope is realized. The entire trimming process can be completed synchronously with the ramming process, that is, ramming can be completed while trimming, avoiding subsequent filling operations and further improving the trimming efficiency.

[0025] (3) By utilizing the ramming process of the device, that is, the reciprocating up and down displacement of the ramming and trimming component, and the cooperation between the ramming and trimming component, the overflow tank, and the auxiliary leveling component, the relative displacement of the two leveling plates is realized. While completing the ramming and trimming of the slope, the convex part of the slope can be trimmed and leveled. The entire process can be completed synchronously, and ramming and convex trimming can be completed simultaneously, significantly improving the overall trimming efficiency.

Detailed implementation mode

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1 to 8 shown, in the embodiment of the present invention, a high-fill embankment slope trimming device for water conservancy construction includes a frame 1. Longitudinal guide rails 2 are fixedly installed on both the left and right sides of the top end of the frame 1. A hoisting member 3 is provided above the frame 1. The left and right sides of the bottom end of the hoisting member 3 are connected to the top ends of the longitudinal guide rails 2. A dual-axis motor 4 is installed in the middle of the bottom end of the hoisting member 3. The left and right ends of the dual-axis motor 4 are connected to a power assembly 6. The front and rear sides of the power assembly 6 are movably clamped with the longitudinal guide rails 2. A ramming and trimming assembly 7 is installed at the bottom end of the power assembly 6. The ramming and trimming assembly 7 reciprocates up and down relative to the longitudinal guide rails 2 through the power assembly 6. An overflow tank 8 is provided on one side of the ramming and trimming assembly 7. An overflow pipe 9 is fixedly connected to the top end of the overflow tank 8. The other end of the overflow pipe 9 is connected to the ramming and trimming assembly 7. A three-way valve 10 is fixedly connected to the middle of the bottom end of the overflow tank 8. A transverse guide rail 5 is fixedly installed on the other side of the frame 1. Auxiliary leveling assemblies 11 are movably clamped on both the front and rear sides of the bottom end of the transverse guide rail 5. The top ends of the auxiliary leveling assemblies 11 are connected to the bottom end of the overflow tank 8. The front and rear ends of the three-way valve 10 are connected to the ramming and trimming assembly 7.

[0037] Among them, a material conveying mechanism is installed inside the overflow tank 8 for conveying sand into the three-way valve 10.

[0038] Before trimming the slope, the external frames can be connected through the lifting member 3, and the inclination angle of the device can be adjusted to ensure that the bottom end of the ramming and trimming assembly 7 is perpendicular to the slope. At the same time, an external traction device is used to drive the device to move up and down relative to the slope to complete the traction process. At the same time, the sand content inside the ramming and trimming assembly 7 needs to be adjusted according to the ramming pressure required by the slope to meet the ramming and trimming requirements.

[0039] As Figure 1 and Figure 2 and Figure 3 As shown, the power assembly 6 includes a guide frame 601. The front and rear ends of the guide frame 601 are movably clamped between two longitudinal guide rails 2. The guide frame 601 moves up and down relative to the longitudinal guide rails 2. On the left and right sides of the top end of the guide frame 601, extension seats 602 are fixedly installed. One end of the extension seat 602 away from the guide frame 601 is movably connected to a first connecting rod 603 through a rotating shaft. One end of the first connecting rod 603 away from the extension seat 602 is movably connected to a second connecting rod 604 through a rotating shaft. One end of the second connecting rod 604 is connected to the output end of the double-shaft motor 4.

[0040] When the ramming and trimming assembly 7 is perpendicular to the slope, the preparation before slope ramming and trimming can be maintained. At this time, the double-shaft motor 4 can be started to drive the second connecting rod 604 to rotate. At this time, the corresponding first connecting rod 603 will swing accordingly, and apply an upward pulling force and a downward pushing force to the extension seat 602, and drive the guide frame 601 to reciprocate up and down, so as to synchronously drive the ramming and trimming assembly 7 and the overflow tank 8 at the bottom to reciprocate up and down.

[0041] As Figure 1 and Figure 4 and Figure 5 As shown, the ramming and trimming assembly 7 includes a pressure tank 701. The middle of the top end of the pressure tank 701 is connected to the bottom end of the guide frame 601. The inside of the pressure tank 701 is filled with sand. An overflow port 705 is fixedly communicated with the top end of the pressure tank 701 on the side close to the overflow tank 8. The overflow port 705 is communicated with an overflow pipe 9. A locking ring frame 702 is fixedly sleeved on the outer side of the pressure tank 701 near the bottom end. Feeding valves 703 are installed at the front and rear ends of the locking ring frame 702. The top ends of the feeding valves 703 are fixedly communicated with feeding hoses 704. The other ends of the feeding hoses 704 are communicated with a three-way valve 10.

[0042] Embodiment: When the pressure tank 701 reciprocates up and down under the action of the guide frame 601, the slope at a specified position can be compacted by the cooperation of the pressure tank 701 and the sand inside. At the same time, since the device is parallel to the slope before compaction, the sand inside the pressure tank 701 can be inclined at this time. The inclined sand can overflow through the overflow port 705, and then through the overflow pipe 9 and enter the inside of the overflow tank 8 for temporary storage. At this time, the inclined part of the sand inside the pressure tank 701 can be exported, and the center of gravity of the pressure tank 701 is adjusted. At this time, the reciprocating displacement of the pressure tank 701 can apply an appropriate pressure to the slope to complete the uniform pressure application process.

[0043] By arranging an overflow tank 8 on one side of the compaction and trimming assembly 7, and through the cooperation between the compaction and trimming assembly 7 and the overflow tank 8, when the compaction and trimming assembly 7 is inclined, the sand in the inclined state can be automatically exported and enter the inside of the overflow tank 8 for temporary storage. At the same time, the amount of exported sand is positively correlated with the inclination angle, which can ensure the automatic adjustment of the center of gravity of the pressure tank 701 during inclination. The entire adjustment process does not need to be completed manually, which can ensure a uniform pressure during inclined compaction and trimming and improve the compaction quality.

[0044] When the compaction of the slope at one position is completed, the device can be towed along the slope downward by an external towing device. When a depression appears at the specified compaction position, the feeding mechanism inside the overflow tank 8 can be opened, and the sand temporarily stored inside the overflow tank 8 can be input into the inside of the three-way valve 10. At the same time, the valves at both the left and right ends of the three-way valve 10 are opened, and the sand then enters the inside of the injection valve 703 through the three-way valve 10 and the feeding hose 704. By opening the injection valve 703, the sand can be injected into the depression to complete the automatic filling of the slope depression and complete the self-trimming process.

[0045] By utilizing the sand overflowed when the device is inclined and the cooperation between the compaction and trimming assembly 7 and the overflow tank 8, when the device reaches the slope depression, the sand can be exported to self-fill the depression. Through the self-filling of the device, the automatic trimming of the slope depression is realized. The entire trimming process can be completed synchronously with the compaction process, that is, compaction can be completed while trimming, avoiding subsequent filling operations and further improving the trimming efficiency.

[0046] Such as Figure 1 and Figure 7As shown in FIG. 8, the auxiliary flattening assembly 11 includes a first fixing base 111. The top end of the first fixing base 111 is connected to the positions near the four corners at the bottom end of the overflow tank 8. One end of the first fixing base 111 away from the overflow tank 8 is movably connected to a support rod 114 through a rotating shaft. One end of the support rod 114 away from the first fixing base 111 is movably connected to a second fixing base 112 through a rotating shaft. A guide block 113 is installed at the bottom end of the second fixing base 112. The guide block 113 is movably clamped with the transverse guide rail 5. Flattening plates 115 are fixedly installed at the bottom ends of the guide blocks 113. The bottom ends of the flattening plates 115 are always in contact with the surface of the slope. The flattening plates 115 move relatively closer to or away from each other driven by the support rods 114.

[0047] Embodiment: When the pressure tank 701 realizes the tamping and trimming of the slope through reciprocating up and down displacement, the overflow tank 8 can be synchronously driven to reciprocate up and down. At this time, the support rod 114 can be synchronously driven to deflect, and a thrust and a pull force are applied to the guide block 113 at the bottom end. At this time, the guide block 113 can drive the flattening plate 115 at the bottom end to reciprocate left and right under the guiding action of the transverse guide rail 5, that is, to keep relatively close to or relatively far from each other. When the two flattening plates 115 keep relative movement, the slope soil at the bottom end can be flattened, and the flattening process of the excess sand on the slope is completed.

[0048] By utilizing the tamping process of the device, that is, using the reciprocating up and down displacement of the tamping and trimming assembly 7, and using the cooperation between the tamping and trimming assembly 7, the overflow tank 8 and the auxiliary flattening assembly 11, the relative displacement of the two flattening plates 115 is realized. While completing the tamping and trimming of the slope, the convex parts of the slope can be trimmed and flattened. The whole process can be completed synchronously, and tamping and convex trimming can be completed at the same time, significantly improving the overall trimming efficiency.

[0049] Working principle and usage process:

[0050] Before trimming the slope, the external frame can be connected through the lifting member 3, and the inclination angle of the device can be adjusted to ensure that the bottom end of the tamping and trimming assembly 7 is perpendicular to the slope. At the same time, an external traction device is used to drive the device to reciprocate up and down relative to the slope to complete the traction process. At the same time, the sand content inside the tamping and trimming assembly 7 needs to be adjusted according to the required tamping pressure of the slope to meet the tamping and trimming requirements;

[0051] When the tamping and trimming assembly 7 is perpendicular to the slope, the preparation before slope tamping and trimming can be maintained. At this time, the double-shaft motor 4 can be started to drive the second connecting rod 604 to rotate. At this time, the corresponding first connecting rod 603 will swing accordingly, and an upward pull force and a downward thrust are applied to the extension seat 602, and the guide frame 601 is driven to reciprocate up and down, so as to synchronously drive the bottom-end tamping and trimming assembly 7 and the overflow tank 8 to reciprocate up and down;

[0052] When the pressure tank 701 reciprocates up and down under the action of the guide frame 601, the slope at the designated position can be compacted by the cooperation of the pressure tank 701 and the sand inside. At the same time, since the device is parallel to the slope before compaction, the sand inside the pressure tank 701 can be inclined at this time. The inclined sand can overflow through the overflow port 705, and through the overflow pipe 9, and enter the inside of the overflow tank 8 for temporary storage. At this time, the inclined part of the sand inside the pressure tank 701 can be exported, and the center of gravity of the pressure tank 701 is adjusted. At this time, the reciprocating displacement of the pressure tank 701 can apply an appropriate pressure to the slope to complete the uniform pressure application process;

[0053] When the compaction of the slope at one position is completed, the device can be towed along the slope downward by an external towing device. When a depression appears at the designated compaction position, the feeding mechanism inside the overflow tank 8 can be opened, and the sand temporarily stored inside the overflow tank 8 can be input into the inside of the three-way valve 10. At the same time, the valves at both the left and right ends of the three-way valve 10 are opened, and the sand then enters the inside of the injection valve 703 through the three-way valve 10 and the feeding hose 704. By opening the injection valve 703, the sand can be injected into the depression to complete the automatic filling of the slope depression and complete the self-trimming process;

[0054] When the pressure tank 701 realizes the compaction and trimming of the slope through reciprocating up and down displacement, the overflow tank 8 can be synchronously driven to reciprocate up and down. At this time, the support rod 114 can be synchronously driven to deflect, and a thrust and a pull force are applied to the guide block 113 at the bottom end. At this time, the guide block 113 can drive the leveling plate 115 at the bottom end to reciprocate left and right under the guiding action of the transverse guide rail 5, that is, to keep relatively close or relatively far away. When the two leveling plates 115 are in relative motion, the slope soil at the bottom end can be leveled to complete the leveling process of the excess sand on the slope.

The scope of the present invention is defined by the appended claims and their equivalents.
