Description

Technical Field

[0001] This invention relates to the field of roadbed construction, and in particular to a vibratory compaction device and vibratory compaction operation method for backfill areas. Background Technology

[0002] Earthwork backfilling refers to the filling of soil in construction projects, mainly including foundation filling, backfilling of foundation pits (trenches) or pipe trenches, indoor floor backfilling, and outdoor site backfilling and leveling. After backfilling, the backfilled area usually needs to be compacted. Compaction methods generally include rolling, tamping, vibratory compaction, and compaction using earthmoving equipment.

[0003] Chinese Patent Application Publication No. CN112376541A discloses a vibratory compaction device and method for backfill areas. The device includes a hammer with a vibrating mechanism mounted on it. The hammer comprises a spherical base for providing the hemispherical surface. The hammer also includes a counterweight detachably connected to the base, the counterweight being a columnar structure. The center of the hemispherical surface is located on the axis of the counterweight. A lifting lug is located on the top of the counterweight. In use, the hammer is lifted by a hoisting device, and its weight causes it to fall onto the backfill area, thus compacting the backfill.

[0004] The aforementioned technologies have the following technical drawbacks: When connecting the counterweight to the hoisting equipment, it is usually necessary to manually connect the lifting lug to the hook of the hoisting equipment. These hooks typically have automatic opening and closing functions to enable the counterweight to fall automatically from a height. However, after releasing the counterweight, the hook may swing due to position adjustments or wind. When it is necessary to connect the hook to the counterweight again, the operator needs to manually assist in stabilizing the swing of the hook. This manual assistance method makes it inconvenient to drive the counterweight for the next compaction. Summary of the Invention

[0005] Therefore, in order to facilitate the driving of the hammer to achieve the next compaction, the present invention provides a vibratory compaction device and a vibratory compaction operation method for backfill areas.

[0006] This invention is implemented as follows: a vibratory compaction device for backfill areas is constructed, including a counterweight and a hoisting device. The hoisting device includes a base plate and a plate body. The base plate is provided with an adjustment device for adjusting the position and height of the plate body along the circumference of the base plate. The plate body is provided with a hoisting component, which includes a winding roller and a hoisting motor for driving the winding roller to rotate. The hoisting motor is fixedly mounted on the plate body. A steel wire rope is wound on the winding roller. One end of the steel wire rope is fixedly mounted on the winding roller, and the other end is provided with a connecting plate. The counterweight includes a connecting block. The connecting plate and the connecting block are provided with an installation mechanism for automatically fixing the connecting block to the connecting plate or automatically separating the connecting block from the connecting plate. The base plate is provided with a stabilizing device for stabilizing the swing of the steel wire rope.

[0007] By adopting the above technical solution, the hoisting motor drives the winding roller to rotate, which in turn drives the wire rope to wind up and down. This causes the wire rope to lift and lower the connecting plate. The connecting plate can be fixed to the connecting block through the installation mechanism, allowing the connecting block to drive the hammer to fall and achieve compaction. The use of an adjustment device facilitates the hammer to fall at different positions, thereby achieving compaction at different locations. The use of a stabilizing device stabilizes the swing of the wire rope, eliminating the need for manual assistance from operators. This facilitates the wire rope driving the connecting plate to fix the hammer for the next time, prevents the swing of the wire rope from causing injury to nearby personnel, and improves the compaction efficiency of multiple hammer compactions to a certain extent.

[0008] Optionally, the adjusting device includes a rotating plate and a lifting plate. The base plate is provided with a rotating mechanism for driving the rotating plate to rotate, the rotating plate is provided with a lifting mechanism for driving the lifting plate to rise and fall, and the lifting plate is provided with a first moving mechanism for adjusting the distance between the plate body and the lifting plate.

[0009] By adopting the above technical solution, the rotating plate is driven to rotate by the rotating mechanism, thereby adjusting the position of the hammer along the circumference of the base plate. The lifting plate is driven to rise and fall by the lifting mechanism to facilitate the adjustment of the height of the hammer. The plate is driven to move towards or away from the lifting plate by the first moving mechanism, thereby facilitating the adjustment of the distance between the hammer and the base plate. This allows the hammer to be positioned at different locations for compaction, thus improving the compaction range of the hammer.

[0010] Optionally, a cylinder is fixedly mounted on the rotating plate, and a lifting rod is inserted into and slidably connected to the cylinder. The lifting plate is fixedly mounted on the end of the lifting rod away from the bottom plate. Slide grooves are opened inside the cylinder and on both sides of the cylinder. Slider blocks are fixedly mounted on both sides of the lifting rod and slidably connected to the slide grooves on both sides. The lifting mechanism includes a screw that is rotatably mounted inside the cylinder along the length direction of the cylinder. The lifting rod is sleeved on and threadedly connected to the screw. A lifting motor for driving the screw to rotate is fixedly mounted inside the cylinder.

[0011] By adopting the above technical solution, the lifting motor drives the screw to rotate. Because the slider is slidably set in the groove, the lifting rod will not rotate with the screw. This allows the lifting rod to move on the screw, and the lifting rod can drive the lifting plate to rise and fall. This allows the lifting plate to drive the counterweight to adjust the height. The screw-driven method can automatically fix the lifting plate to the moved position, improving the driving effect of the lifting plate.

[0012] Optionally, the stabilizing device includes a stabilizing rod fixedly mounted on the cylinder along its length, a movable plate slidably mounted on the stabilizing rod along its length, a driving mechanism for moving the movable plate along its length, a stabilizing frame for passing a steel wire rope through the movable plate, and a second moving mechanism for adjusting the distance between the stabilizing frame and the movable plate.

[0013] By adopting the above technical solution, the wire rope passes through the stabilizing frame. When the wire rope needs to be stabilized, the stabilizing frame is driven to descend by the driving mechanism, so that the stabilizing frame drives the wire rope to swing stably. The stabilizing rod is set on the cylinder so that the stabilizing rod can rotate synchronously with the cylinder. The position of the second moving mechanism is convenient to adjust the position of the stabilizing frame to follow the wire rope, thereby improving the stabilizing effect of the stabilizing frame on the wire rope.

[0014] Optionally, a drive groove is provided on the stabilizer bar along its length direction, a drive block is fixedly provided on the movable plate and slidably connected in the drive groove, the drive mechanism includes a lead screw rotatably provided in the drive groove along its length direction, the drive block is sleeved and threadedly connected to the lead screw, and a drive motor for driving the lead screw to rotate is fixedly provided at the end of the stabilizer bar away from the base plate.

[0015] By adopting the above technical solution, the drive motor drives the lead screw to rotate. Because the drive block is slidably set in the drive groove, the drive block will not rotate with the rotation of the lead screw. This causes the drive block to drive the moving plate to rise and fall, and the moving plate to drive the stabilizing frame to rise and fall. The use of the lead screw can fix the stabilizing frame to any position after movement, thus improving the driving effect of the stabilizing frame.

[0016] Optionally, the stabilizing frame includes a U-shaped frame and an opening / closing rod hinged to the U-shaped frame for opening or closing the U-shaped frame. The U-shaped frame is provided with an opening / closing mechanism for driving the opening / closing rod to rotate on the U-shaped frame.

[0017] By adopting the above technical solution, the opening and closing mechanism drives the opening and closing rod to rotate on the U-shaped frame, so that the opening and closing rod opens or closes the U-shaped frame, thereby facilitating the removal of the wire rope within the stabilizing frame and preventing the stabilizing frame from affecting the lifting and lowering of the wire rope.

[0018] Optionally, a hinge shaft is fixedly provided on the opening and closing rod and rotatably connected to the U-shaped frame. The opening and closing mechanism includes a worm gear, a worm, and an opening and closing motor. The worm gear is sleeved and fixedly connected to the hinge shaft. The worm is fixedly provided on the drive end of the opening and closing motor and meshes with the worm gear. The opening and closing motor is fixedly provided on the U-shaped frame.

[0019] By adopting the above technical solution, the opening and closing motor drives the worm gear to rotate, which in turn drives the hinge shaft to rotate. The hinge shaft can then drive the opening and closing rod to rotate, thereby enabling the opening and closing rod to open or close the U-shaped frame. The worm gear and worm wheel drive method can fix the opening and closing rod to any moved position, improving the driving effect of the opening and closing rod.

[0020] Optionally, slots are provided on the connecting block and on both sides of the connecting block, and plugs for insertion into the slots on both sides are provided on the connecting plate and on both sides of the connecting plate. Both plugs are electromagnets. The mounting mechanism includes a metal block fixedly disposed on the bottom wall of the slot for attraction with the electromagnet.

[0021] By adopting the above technical solution, the electromagnet is energized so that it can attract the metal block. When it is necessary to drive the hammer to fall freely, the electromagnet can be de-energized. The combination of electromagnet and metal block has a simple structure and improves the fixing effect of the connecting block.

[0022] According to the above-mentioned vibration compaction operation method of the backfill area vibration compaction device, the implementation process of the backfill area vibration compaction device is as follows: when it is necessary to drive the hammer 1 to compact, the hoisting motor drives the winding roller to rotate, so that the winding roller drives the wire rope to rise. The opening and closing motor drives the worm gear to rotate, so that the worm wheel drives the hinge shaft to rotate. The opening and closing rod can drive the U-shaped frame to open. The rotating motor drives the rotating gear to rotate, so that the rotating gear ring drives the rotating shaft to rotate. The lifting motor drives the screw to rotate, so that the lifting rod drives the lifting plate to rise and fall. The first moving electric cylinder drives the plate to move, thereby adjusting the falling position of the hammer. By driving the electromagnet to de-energize, the insert block is disengaged from the slot. At this time, the hammer can fall. After the hammer falls, the second moving electric cylinder drives the stabilizing frame to move, so that the wire rope moves into the stabilizing frame. The drive motor drives the screw to rotate, so that the moving plate drives the stabilizing frame to fall, thereby stabilizing the swing of the wire rope. No operator assistance is required, which facilitates the next hammer compaction and prevents the operator from being injured nearby.

[0023] The present invention has the following advantages: 1. The hoisting motor drives the winding roller to rotate, which in turn drives the wire rope to wind up and down. The wire rope then drives the connecting plate to rise and fall. The connecting plate can be fixed to the connecting block through the installation mechanism, allowing the connecting block to drive the hammer to fall and achieve compaction. The use of an adjustment device makes it easy to move the hammer to different positions to achieve compaction at different locations. The use of a stabilizing device can stabilize the swing of the wire rope, thus eliminating the need for manual assistance from the operator to stabilize the wire rope. This facilitates the wire rope to drive the connecting plate to fix the hammer for the next time, and can prevent the swing of the wire rope from causing injury to nearby personnel. At the same time, it can improve the compaction efficiency of multiple hammer compaction to a certain extent. 2. The wire rope passes through the stabilizing frame. When the wire rope needs to be stabilized, the stabilizing frame is driven to descend by the driving mechanism, so that the stabilizing frame drives the wire rope to swing stably. The stabilizing rod is set on the cylinder so that the stabilizing rod can rotate synchronously with the cylinder. The position of the second moving mechanism is convenient to adjust the position of the stabilizing frame to follow the wire rope, which improves the stabilizing effect of the stabilizing frame on the wire rope. 3. The opening and closing mechanism drives the opening and closing rod to rotate on the U-shaped frame, so that the opening and closing rod opens or closes the U-shaped frame, thereby facilitating the removal of the wire rope within the stabilizing frame and preventing the stabilizing frame from affecting the lifting and lowering of the wire rope.

Detailed Implementation

[0026] The following will be combined with the appendix Figures 1-5 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] This invention provides, through improvements, a vibratory compaction device for backfill areas. (See reference...) Figure 1 It includes a weight 1, which includes a connecting block 11 and a sphere 111. The sphere 111 is hemispherical, and the connecting block 11 is fixedly mounted on the hemispherical sphere 111.

[0028] The vibratory compaction device also includes a hoisting device, which includes a base plate 12 and a plate body 121. In this embodiment, the base plate 12 is provided with a rod 17, and the rod 17 is provided with a plurality of barbs 171 for fixing the rod 17 to the ground. The plate body 121 is provided with a hoisting component, which includes a winding roller 122 and a hoisting motor 123 for driving the winding roller 122 to rotate. The hoisting motor 123 is fixedly installed on the plate body 121. The cross-section of the winding roller 122 is "H" shaped. A steel wire rope 124 is wound on the winding roller 122. One end of the steel wire rope 124 is fixedly installed on the winding roller 122, and the other end is fixedly installed with a connecting plate 125. The connecting plate 125 and the connecting block 11 are provided with an installation mechanism for automatically fixing the connecting block 11 to the connecting plate 125 or automatically separating the connecting block 11 from the connecting plate 125.

[0029] Combination Figure 1 and Figure 2 The connecting block 11 has slots 126 on both sides, and the connecting plate 125 has inserts 127 on both sides for insertion into the slots 126. Both inserts 127 are electromagnets. The mounting mechanism includes a metal block 128 fixedly mounted on the bottom wall of the slot 126 for attraction with the electromagnet. In this embodiment, the metal block 128 is made of iron.

[0030] like Figure 1 As shown, in order to adjust the falling position of the weight 1, the base plate 12 is provided with an adjustment device for adjusting the position and height of the plate 121 along the circumference of the base plate 12. The adjustment device includes a rotating plate 13 and a lifting plate 131. The base plate 12 is provided with a rotating mechanism for driving the rotating plate 13 to rotate. The rotating plate 13 is provided with a lifting mechanism for driving the lifting plate 131 to rise and fall. The lifting plate 131 is provided with a first moving mechanism for adjusting the distance between the plate 121 and the lifting plate 131.

[0031] like Figure 1 As shown, in this embodiment, a rotating shaft 132 is fixedly provided on the rotating plate 13 and rotatably connected to the base plate 12. The rotating mechanism includes a rotating motor 133, a rotating gear 134, and a rotating gear ring 135. The rotating motor 133 is fixedly provided on the base plate 12, the rotating gear 134 is fixedly provided on the drive end of the rotating motor 133, and the rotating gear ring 135 is sleeved on and fixedly connected to the rotating shaft 132. The rotating gear 134 and the rotating gear ring 135 are meshed together.

[0032] Combination Figure 1 and Figure 3A cylinder 14 is fixedly mounted on the rotating plate 13. A lifting rod 141 is inserted into and slidably connected to the cylinder 14. The lifting plate 131 is fixedly mounted on the end of the lifting rod 141 away from the bottom plate 12. Sliding grooves 142 are provided inside the cylinder 14 and on both sides of the cylinder 14 (see...). Figure 4 The lifting rod 141 has sliders 143 fixedly installed on both sides of the lifting rod 141 and slidably connected in the sliding grooves 142 on both sides. In this embodiment, the cross-section of the sliding groove 142 is set as "U" shaped, and the sliders 143 are configured to cooperate with the "U" shaped sliding groove 142. The lifting mechanism includes a screw 144 rotatably installed in the cylinder 14 along the length direction of the cylinder 14. The lifting rod 141 is sleeved and threadedly connected to the screw 144. A lifting motor 145 for driving the screw 144 to rotate is fixedly installed in the cylinder 14. In this embodiment, the first moving mechanism includes a first moving electric cylinder 146 fixedly installed on the lifting plate 131, and the plate 121 is fixedly installed on the driving end of the first moving electric cylinder 146.

[0033] The lifting motor 145 drives the screw 144 to rotate. Because the slider 143 is slidably set in the slide groove 142, the lifting rod 141 will not rotate with the rotation of the screw 144. Thus, the lifting rod 141 moves on the screw 144. The lifting rod 141 can drive the lifting plate 131 to rise and fall, so that the lifting plate 131 drives the counterweight 1 to rise and fall.

[0034] Combination Figure 1 and Figure 3 To prevent the wire rope 124 from swinging, a stabilizing device is provided on the base plate 12 to stabilize the swing of the wire rope 124. The stabilizing device includes a stabilizing rod 15 fixedly installed on the cylinder 14 along the length direction of the cylinder 14. The stabilizing rod 15 is integrally installed with the cylinder 14. A movable plate 151 is slidably installed on the stabilizing rod 15 along the length direction of the stabilizing rod 15. A driving mechanism is provided on the stabilizing rod 15 to drive the movable plate 151 to move along the length direction of the stabilizing rod 15. A stabilizing frame 152 is provided on the movable plate 151 for the wire rope 124 to pass through.

[0035] Combination Figure 1 and Figure 3 A drive groove 153 is provided on the stabilizer bar 15 along the length direction of the stabilizer bar 15. A drive block 154 is fixedly provided on the moving plate 151 and slidably connected in the drive groove 153. In this embodiment, the cross-section of the drive groove 153 is set as "T" shaped. The drive block 154 is configured to cooperate with the "T" shaped drive groove 153. The drive mechanism includes a lead screw 155 rotatably disposed in the drive groove 153 along the length direction of the drive groove 153. The drive block 154 is sleeved and threadedly connected to the lead screw 155. A drive motor 156 for driving the lead screw 155 to rotate is fixedly provided at the end of the stabilizer bar 15 away from the base plate 12.

[0036] The drive motor 156 drives the lead screw 155 to rotate. Since the drive block 154 is slidably set in the drive groove 153, the drive block 154 will not rotate with the rotation of the lead screw 155. The drive block 154 can move on the lead screw 155, so that the drive block 154 drives the moving plate 151 to move, thereby causing the moving plate 151 to drive the stabilizing frame 152 to rise and fall.

[0037] like Figure 1 As shown, a second moving mechanism for adjusting the distance between the stabilizing frame 152 and the moving plate 151 is provided on the moving plate 151; in this embodiment, the second moving mechanism includes a second moving electric cylinder 157 fixedly disposed on the moving plate 151, and the stabilizing frame 152 is fixedly disposed on the driving end of the second moving electric cylinder 157.

[0038] Combination Figure 1 and Figure 5 The stabilizing frame 152 includes a U-shaped frame 16 and an opening / closing rod 161 hinged to the U-shaped frame 16 for opening or closing the U-shaped frame 16. The U-shaped frame 16 is fixedly mounted on the drive end of the second moving electric cylinder 157. The U-shaped frame 16 is provided with an opening / closing mechanism for driving the opening / closing rod 161 to rotate on the U-shaped frame 16.

[0039] like Figure 5 As shown, a hinge shaft 162 is fixedly installed on the opening and closing rod 161 and rotatably connected to the U-shaped frame 16. The opening and closing mechanism includes a worm gear 163, a worm 164, and an opening and closing motor 165. The worm gear 163 is sleeved and fixedly connected to the hinge shaft 162. The worm 164 is fixedly installed on the drive end of the opening and closing motor 165 and meshes with the worm gear 163. The opening and closing motor 165 is fixedly installed on the U-shaped frame 16. The opening and closing motor 165 drives the worm 164 to rotate, which causes the worm gear 163 to drive the hinge shaft 162 to rotate, thereby causing the hinge shaft 162 to drive the opening and closing rod 161 to open or close the U-shaped frame 16.

[0040] The implementation principle of a vibration compaction device for backfill areas according to an embodiment of this application is as follows: When it is necessary to drive the hammer 1 for compaction, the hoisting motor 123 drives the winding roller 122 to rotate, causing the winding roller 122 to drive the wire rope 124 to rise. The opening and closing motor 165 drives the worm gear 164 to rotate, causing the worm wheel 163 to drive the hinge shaft 162 to rotate. The opening and closing rod 161 can drive the U-shaped frame 16 to open. The rotating motor 133 drives the rotating gear 134 to rotate, causing the rotating gear ring 135 to drive the rotating shaft 132 to rotate. The lifting motor 145 drives the screw 144 to rotate, causing the lifting rod 141 to drive the lifting plate 131. The lifting mechanism is achieved by moving the plate 121 via the first moving electric cylinder, thereby adjusting the falling position of the hammer 1. By de-energizing the electromagnet, the insert 127 disengages from the slot 126, allowing the hammer 1 to fall. After the hammer 1 falls, the second moving electric cylinder 157 moves the stabilizing frame 152, causing the wire rope 124 to move into the stabilizing frame 152. The drive motor 156 drives the lead screw 155 to rotate, causing the moving plate 151 to lower the stabilizing frame 152, thus stabilizing the swing of the wire rope 124. No operator assistance is required, facilitating the next compaction of the hammer 1 and preventing injury to nearby operators.

The rotating gear (134) and the rotating gear ring (135) are meshed.

6. The vibration compaction operation method of the backfill area vibration compaction device according to claim 5, characterized in that: The implementation process of the vibratory compaction device for the backfill area is as follows: When it is necessary to drive the hammer to compact, the hoisting motor drives the winding roller to rotate, causing the winding roller to drive the wire rope to rise. The opening and closing motor drives the worm gear to rotate, causing the worm wheel to drive the hinge shaft to rotate. The opening and closing rod drives the U-shaped frame to open. The rotating motor drives the rotating gear to rotate, causing the rotating gear ring to drive the rotating shaft to rotate. The lifting motor drives the screw to rotate, causing the lifting rod to drive the lifting plate to rise and fall. The first moving mechanism drives the plate to move, thereby adjusting the falling position of the hammer. By driving the electromagnet to de-energize, the insert block is disengaged from the slot, and the hammer can fall. After the hammer falls, the second moving mechanism drives the stabilizing frame to move, causing the wire rope to move into the stabilizing frame. The drive motor drives the screw to rotate, causing the moving plate to drive the stabilizing frame to fall, thereby stabilizing the swing of the wire rope. No operator assistance is required, which facilitates the next hammer compaction and prevents operators from being injured nearby.
