Description

Technical Field

[0001] The invention relates to the technical field of high slope earthwork compaction, in particular to a high slope earthwork rapid compaction device for filling. Background Art

[0002] High slopes refer to slopes that have a great impact on project safety. High earth slopes usually refer to slopes over 15 meters. They have poor stability and are easily unstable due to various factors. After construction on high slopes, they need to be backfilled with earth. This type of engineering operation is often used in road construction, site leveling, water conservancy projects and other fields. By filling the high slope area with earth that meets the requirements in layers and performing compaction and other treatments, the designed project elevation and slope stability requirements can be achieved.

[0003] In the existing practice, when compacting the earthwork on high slopes, large-scale machinery cannot be used because the slope of the high slope is relatively large, so most of the time, manually operated rammers are used to compact the earthwork. However, due to the large angle and uneven slope surface of the high slope, when manually operating the rammer, the operator is prone to slipping due to unstable feet during movement, which poses a safety hazard. At the same time, since the rammer itself has a certain weight, operating it on a high slope requires the operator to exert more physical strength to control its movement and operation. Long-term operation can easily make the operator tired, thereby reducing work efficiency. Summary of the Invention

This high slope filling earthwork rapid compaction device cooperates with the compaction plate 114 through the frame 100 to facilitate compaction of the earthwork on the high slope, without the need for manual operation standing on the slope surface, making construction safer and more efficient. The moving wheels 133 cooperate with the U-shaped mounting frame 132 to facilitate movement of the frame 100 on the high slope, thereby facilitating subsequent compaction operations on the high slope. At the same time, the ground plug 141 is used to improve the stability of the frame 100 during the compaction operation.

[0032] Please refer to Figure 1 Figure 4 and Figure 5The fixed horizontal plate 200 is located on the right side of the frame 100, and the top of the fixed horizontal plate 200 is slidably connected to the traction frame 210. A winding drum 211 is provided on the inner side of the traction frame 210. The rear side wall of the traction frame 210 is fixedly connected to the second stepping motor 220 by bolts. The output shaft of the second stepping motor 220 is fixedly connected to the rear side wall of the winding drum 211, and the front side wall of the winding drum 211 is rotatably connected to the inner side wall of the traction frame 210 through a bearing. An adjusting slot 221 is provided on the top left side of the fixed horizontal plate 200, and an adjusting slider 222 is slidably connected to the inner cavity wall of the adjusting slot 221.

It is fixedly connected to the adjusting slider 222 through bolts, and the front and rear sides of the right side wall of the frame 100 are fixedly connected with connecting rings 230. The outer wall of the winding drum 211 is wrapped with a steel wire rope, and the end of the steel wire rope is fixedly connected to the connecting ring 230. The right side wall of the fixed cross plate 200 is fixedly connected with a fixed hole block 240, and the fixed hole blocks 240 are evenly distributed. This high slope filling earthwork rapid compaction device adjusts the longitudinal position of the frame 100 on the slope surface through the connecting ring 230 in conjunction with the winding drum 211 and the second stepper motor 220, and adjusts the lateral position of the frame 100 on the slope surface through the traction frame 210 in conjunction with the adjusting slider 222 and the bolt hole 223. The two cooperate with each other to facilitate positioning of the construction position, thereby realizing all-round construction of the high slope.

[0033] When the present invention is in use: the fixed horizontal plate 200 is placed on the top of the slope, and the ground nails are inserted into the fixed hole blocks 240 and then driven into the ground to fix the fixed horizontal plate 200. Then the frame 100 is placed on the slope, and the power of the second stepper motor 220 is turned on. The output shaft of the second stepper motor 220 rotates to drive the winding drum 211 to rotate slowly and uniformly. The winding drum 211 rotates to release the wound wire rope. At this time, the wire rope cooperates with the connecting ring 230 to slowly release the frame 100. The frame 100 cooperates with the moving wheel 133 and the U-shaped mounting bracket 132 to slide to the bottom of the slope under the action of its own gravity. When the frame 100 reaches the construction position, the second stepper motor 220 is turned off and the hydraulic cylinder 13 is turned on. 1, the output end of the hydraulic cylinder 131 contracts, and the frame 100 moves downward. When the frame 100 moves downward, it drives the ground plug 141 to move downward. After the ground plug 141 is inserted into the slope, the frame 100 contacts the slope and stops moving, positioning the frame 100 at the construction position. Then, the first stepper motor 121 and the electric push rod 111 are turned on at the same time. The output end of the electric push rod 111 drives the pressing plate 112 to move downward, and the tamping plate 114 cooperates with the limit frame 113 to move downward at the same time to compact the earth on the slope. When the electric push rod 111 reaches the maximum stroke, it drives the tamping plate 114 to reset, and then drives the tamping plate 114 to move downward again, thereby driving the tamping plate 114 to move back and forth to compact the earth. In the compaction process, when encountering a hard soil layer or other obstacles that cause excessive resistance, the spring 115 will first be compressed and deformed, limiting the excessive force transmitted to the electric push rod 111, preventing the electric push rod 111 from being damaged due to overload, and playing a protective role. At the same time, the output shaft of the first stepper motor 121 rotates to drive the reciprocating screw 122 to rotate, and the reciprocating screw 122 rotates to drive the movable frame 110 to move back and forth on the auxiliary rod 123, compacting the earth evenly and expanding the compaction range. After completing the compaction of the earth at the current position, the power of the hydraulic cylinder 131 is turned on, and the output end of the hydraulic cylinder 131 is extended to make the frame 100 move upward and away from the slope. At the same time, the ground plug 141 is pulled out, and the second stepper motor 121 is started. The motor 220 rotates to drive the winding drum 211 to reel in the wire rope, pulling the frame 100 upward to the next construction position. When the longitudinal position of the slope is compacted from bottom to top, the frame 100 is at the top of the slope. At this time, the bolt is turned out from the bolt hole 223 to release the fixation of the adjusting slider 222, and then the traction frame 210 is pushed to drive the adjusting slider 222 to slide in the adjusting slide groove 221, and the traction frame 210 is moved to the next position. The bolt is inserted into the current bolt hole 223 and tightened to fix the adjusting slider 222. Then, after moving the frame 100 to the current position, the above operation can be repeated to compact the current longitudinal slope, and then the slope can be compacted in all directions by performing the above operations in sequence.

[0034] It should be noted that the electric push rod, the first stepper motor, the second stepper motor and the hydraulic cylinder mentioned in the article are all existing traceable technologies. When in use, they are powered by a tow line. The principle of the electric push rod driving the tamping plate to move back and forth is that the existing electric push rod is driven by a motor. The motor generates rotational motion when energized, and the rotational motion is converted into linear telescopic motion of the push rod through a screw drive or a gear rack drive and other mechanisms. The range of motion is then controlled by a limit device, and the start, stop, forward and reverse rotation and speed adjustment of the motor are realized by the control system, thereby accurately controlling the reciprocating movement of the object.

[0035] At the same time, when the frame reaches the position, the output shaft of the second stepper motor stops rotating and will self-lock to prevent the winding drum from rotating. The principle is that the stepper motor self-locks by energizing the stator to generate a magnetic field, aligning the rotor poles with it and maintaining the magnetic field after power is cut off, and using the high matching degree between the rotor and the stator to achieve stable positioning.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
