Description

Technical Field

[0001] This invention relates to the field of civil engineering construction technology, and in particular to a foundation compaction device. Background Technology

[0002] Currently, foundation laying is required before civil construction. Because the foundation is relatively soft after laying, two types of compaction devices are used to strengthen it: one controlled by the excavator's robotic arm, and the other a handheld compactor. However, the current handheld compactor still has the following shortcomings:

[0003] Handheld compactors tend to bounce around during use, making it easy for construction workers to lose control. When compacting at the bottom of a slope, the user needs to apply a pushing and pulling force, which increases labor costs. In addition, prolonged use of the compactor can generate significant heat at the friction points of the engine and rotating shaft, shortening their lifespan.

[0004] Secondly, current compaction devices either repeatedly compact the same spot or use a hopping mechanism to move the device forward. Therefore, construction workers need to select different compaction devices depending on the compaction conditions, which increases the types of compaction devices available and the cost. Summary of the Invention

[0005] In view of this, the present invention provides a foundation compaction device to solve the problem of stable operation of the compaction device while ensuring proper heat dissipation.

A through hole that fits the rotating sleeve is opened on the inner side of the extrusion seat. The extrusion seat is installed on the outer side of the rotating sleeve in conjunction with the through hole.

[0009] Furthermore, the stabilizing frame has a bent friction block on top, and the extrusion seat has three steps and an impact groove. The friction block and the extrusion seat are in contact. A rotatably connected threaded rod is installed on top of the stabilizing frame, and a tamping plate is installed at the bottom of the stabilizing frame. Two stabilizing rods are installed on top of the tamping plate, and the stabilizing rods pass through the bottom of the stabilizing frame.

[0010] Furthermore, the extrusion seat has a mounting hole at one end, and one end of the connecting rod extends into the interior of the mounting hole.

The bottom of the positioning block is inserted into the interior of the positioning groove. A stabilizing plate is installed on one side of the second positioning frame with a bolt.

[0011] Furthermore, the stabilizing base has a set of heat dissipation plates installed on its inner side, with a set of mesh ventilation holes opened on the heat dissipation plates, and a set of blades set on one side of the heat dissipation plates. The heat dissipation plates are located on the outer side of the second rotating shaft.

[0012] Furthermore, the first rotating shaft has a flow groove on its inner side, a drain hole is opened on the flow groove, a flow seat is installed on the outer side of the drain hole, a flow seat is also installed on one end of the rotor of the electric motor, the two ends of the flow pipe are connected to the flow seat respectively, and a small water pump is installed between the water tank and the flow pipe.

[0013] Furthermore, a driven bevel gear is mounted on the outer side of the second rotating shaft, and a driving bevel gear is mounted on one end of the first rotating shaft. The driven bevel gear and the driving bevel gear mesh. The second rotating shaft passes through the interior of the stable base, and an extension rod is mounted on each end of the second rotating shaft. An actuating plate is mounted on the bottom of the extension rod.

[0014] Furthermore, a threaded hole is provided at the sliding groove position of the stabilizing body, and an adjusting bolt is inserted into the threaded hole and rotatably connected to the stabilizing seat.

[0015] The foundation compaction device provided by the present invention has the following beneficial effects:

[0016] 1. An electric motor-driven tamping plate is installed to compact the foundation. A stabilizing frame, friction block, and extrusion seat are installed between the electric motor and the tamping plate. The electric motor drives the extrusion seat to rotate and squeeze the friction block, so as to achieve the effect of the tamping plate jumping up and down. The stabilizing frame, friction block, and extrusion seat replace the complex drive of the current tamping device.

[0017] 2. An actuating plate is installed on the basis of the compaction device. The actuating plate is connected with a bevel gear and a rotating shaft. The driving force of the actuating plate drives the actuating plate to rotate. When the actuating plate rotates, it moves the compaction device to a different position.

[0018] An adjusting bolt is installed. After the construction workers turn the adjusting bolt, the driving force of the push frame and the electric motor is separated, and the compaction device is in a stable state to repeatedly press and hammer the foundation.

[0019] The extrusion seat has three steps. On the foundation of the compaction plate, there is an adjustment assembly consisting of a connecting rod, a stabilizing block, a positioning block, and a positioning frame. After the construction worker pushes the positioning block, the construction worker applies a push-pull force to the positioning block. At this time, the extrusion seat moves under the force to adjust the different steps. Different hammering forces of the compaction plate are achieved according to different steps, and the different hammering forces of the compaction plate are set as simple mechanical adjustments.

[0020] 3. A drainage hole is set on the electric motor and rotating shaft. A water tank and drainage pipe are set on the drainage hole. A small water pump is set to transport water from the water tank to the electric motor and rotating shaft. At this time, the water flow dissipates heat from the electric motor and rotating shaft, extending the service life of the electric motor and the friction life of the rotating shaft.

[0021] In addition, a heat dissipation plate is installed inside the stabilizer. When the heat dissipation plate rotates, it achieves the effect of heat dissipation inside the stabilizer and extends the friction life of the second rotating shaft during rotation. Attached Figure Description

[0046] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0047] Please refer to Figures 1 to 12 As shown:

[0048] Example 1: This invention provides a foundation compaction device, including a stabilizing body 1. A set of rollers is installed at the bottom of the stabilizing body 1. An adjusting bolt 2 and a drive mechanism 3 are installed on the top of the stabilizing body 1. The drive mechanism 3 consists of an electric motor 301, a rotating sleeve 302, a pressing seat 303, and a first rotating shaft 304. The electric motor 301 is installed on top of the stabilizing body 1. A threaded hole is formed in the middle of the rotor of the electric motor 301. The rotating sleeve 302 is connected to the rotor of the electric motor 301. A groove is provided at one end of the rotor of the electric motor 301, and the rotating sleeve 302 is installed inside the groove. Motor 301 drives rotating sleeve 302 to rotate stably. Rotating sleeve 302 has a set of sliding grooves on its outer side. The sliding grooves are arc structures. An extrusion seat 303 has a through hole on its inner side that fits with rotating sleeve 302. Extrusion seat 303 is installed on the outer side of rotating sleeve 302 with the through hole. Extrusion seat 303 rotates stably with the sliding grooves. In addition, with the setting of sliding hole, extrusion seat 303 can move flexibly. First rotating shaft 304 is set at one end of rotating sleeve 302. Electric motor 301 can drive rotating sleeve 302, extrusion seat 303 and first rotating shaft 304 to rotate simultaneously.

[0049] The stabilizing body 1 has a set of compaction structures 4 and a set of adjustment components 5 installed on its inner side. The compaction structure 4 is composed of a stabilizing frame 401, a friction block 402, a compaction plate 403, and a threaded rod 404. The stabilizing body 1 has a threaded positioning plate 101 on top, with a vertical threaded hole. The threaded rod 404 is inserted into the threaded hole. The threaded positioning plate 101, in conjunction with the threaded hole, positions the threaded rod 404. Rotating the threaded rod 404 will cause the compaction structure 4 to rise and fall. After the compaction structure 4 rises, it is convenient to adjust the position of the extrusion seat 303. The stabilizing frame 401 has a bent friction block 4 on top. 02. The extrusion seat 303 is provided with three steps and one impact groove. The friction block 402 is in contact with the extrusion seat 303. When the extrusion seat 303 rotates, it will squeeze the friction block 402, causing the compaction structure 4 to move upward. When the friction block 402 is located in the impact groove, the compaction plate 403 moves downward quickly to compact the foundation surface. The stabilizing frame 401 is equipped with a rotatably connected threaded rod 404 on the top. The stabilizing frame 401 is equipped with a compaction plate 403 at the bottom. The compaction plate 403 is provided with two stabilizing rods on the top. The stabilizing rods pass through the bottom of the stabilizing frame 401. With the cooperation of the stabilizing rods, the stabilizing frame 401 and the compaction plate 403 are stably connected.

[0050] The stabilizing frame 401 has a bent friction block 402 on top. The extrusion seat 303 has three steps and an impact groove. The friction block 402 and the extrusion seat 303 are in contact. When the extrusion seat 303 rotates, it will extrude the friction block 402, causing the compaction structure 4 to move upward. When the friction block 402 is in the position of the impact groove, the compaction plate 403 moves downward quickly to compact the foundation surface. The stabilizing frame 401 has a rotatably connected threaded rod 404 on top. The stabilizing frame 401 has a compaction plate 403 on the bottom. The compaction plate 403 has two stabilizing rods on top. The stabilizing rods pass through the bottom of the stabilizing frame 401. With the cooperation of the stabilizing rods, the stabilizing frame 401 and the compaction plate 403 are stably connected.

[0051] The adjusting assembly 5 consists of a connecting rod 501, a stabilizing block 502, a positioning block 503, a second positioning frame 504, and a stabilizing plate 505. The extrusion seat 303 has a mounting hole at one end. One end of the connecting rod 501 extends into the mounting hole, where a locking bolt is installed. After installation, the connecting rod 501, in conjunction with the locking bolt, achieves a stable connection with the extrusion seat 303. A stepped sliding groove is formed on the upper part of the connecting rod 501. A stabilizing block 502 is installed inside the sliding groove, positioning and stabilizing the sliding position of the stabilizing block 502. A support spring is installed on the outer side of the stabilizing block 502. A positioning block 503 is located above the stabilizing block 502, supporting the spring with the cooperation of the positioning block 503. A spring provides elastic support to the stabilizing block 502. The second positioning frame 504 is located above the stabilizing body 1. The second positioning frame 504 has a set of positioning grooves on its upper part that correspond to the steps of the extrusion seat 303. The bottom of the positioning block 503 is inserted into the interior of the positioning groove. After the construction worker pushes the positioning block 503, the construction worker applies a push-pull force to the positioning block 503. At this time, the extrusion seat 303 moves under the force to adjust different steps. Different hammering forces of the compaction plate 403 are achieved according to different steps. The different hammering forces of the compaction plate 403 are set as simple mechanical adjustments. With the cooperation of the positioning groove and the support spring, the extrusion seat 303 is quickly stabilized after adjustment. A stabilizing plate 505 is installed on one side of the second positioning frame 504 with bolts.

[0052] The stabilizing body 1 has two T-shaped sliding grooves on its upper part. A set of stabilizing seats 6 are installed at the sliding groove positions. A set of heat dissipation plates 601 are installed on the inner side of the stabilizing seats 6. A rotational gap of about one millimeter is set between the heat dissipation plates 601 and the stabilizing seats 6. A set of mesh ventilation holes are opened on the heat dissipation plates 601. A set of blades is set on one side of the heat dissipation plates 601. The heat dissipation plates 601 are located outside the second rotating shaft 801. When the second rotating shaft 801 rotates, it can stably drive the heat dissipation plates 601 to rotate. When the heat dissipation plates 601 rotate, they work with the ventilation holes and blades to achieve the effect of heat dissipation inside the stabilizing seats 6, extending the friction life of the second rotating shaft 801 during rotation. A set of heat dissipation components 7 are installed on the inner side of the stabilizing body 1. The heat dissipation components 7 consist of a water tank 701 and a heat sink 701. The flow pipe 702 is composed of a flow groove on the inner side of the first rotating shaft 304, and a drain hole is opened on the flow groove. A flow guide seat is installed on the outer side of the drain hole. A flow guide seat is also installed at one end of the rotor of the electric motor 301. The flow guide seat is stable against the first rotating shaft 304. The two ends of the flow pipe 702 are connected to the flow guide seat respectively. A small water pump is installed between the water tank 701 and the flow pipe 702. Thus, the small water pump, together with the flow pipe 702, transports the water in the water tank 701 to the inside of the rotor, rotating sleeve 302, and first rotating shaft 304. At this time, the water flow dissipates heat from the rotor, rotating sleeve 302, and first rotating shaft 304, extending the service life of the electric motor 301 and the friction life of the first rotating shaft 304.

[0053] A displacement mechanism 8 is installed at one end of the stabilizing body 1. The displacement mechanism 8 consists of a second rotating shaft 801, an extension rod 802, and a toggle plate 803. A driven bevel gear is installed on the outer side of the second rotating shaft 801, and a driving bevel gear is installed at one end of the first rotating shaft 304. The driven bevel gear and the driving bevel gear mesh. The second rotating shaft 801 passes through the interior of the stabilizing seat 6, and the stabilizing seat 6 stabilizes the rotation and installation position of the second rotating shaft 801. An extension rod 802 is installed at each end of the second rotating shaft 801. When the second rotating shaft 801 rotates, it drives the extension rod 802 to stabilize. Rotating, the extension rod 802 has a deflector plate 803 installed at the bottom. During the movement of the compaction plate 403, the second rotating shaft 801 can drive the deflector plate 803 to rotate. The deflector plate 803 has a set of deflecting teeth on its outer side. When the deflecting teeth move to the position of the foundation, they can push the compaction device to move. A threaded hole is opened at the sliding groove position of the stabilizing body 1. The adjusting bolt 2 is inserted into the threaded hole and rotates to connect with the stabilizing seat 6. Thus, after the construction personnel rotate the adjusting bolt 2, the driving bevel gear and the driven bevel gear separate, and the compaction device is in a stable state to repeatedly press and hammer the foundation.

[0054] Example 2: Based on Example 1, springs are installed on the two stabilizing rods of the compaction plate 403. When the compaction plate 403 is hammered on the foundation surface, the springs can buffer the force of the compaction plate 403, avoiding the phenomenon of numbness in the hands of construction personnel when operating the compaction device.

[0055] The specific usage and function of this embodiment are as follows:

[0056] Before compacting the foundation, the compaction device needs to be assembled. The drive mechanism 3 is installed on the top of the stabilizing body 1 in sequence. Then, the displacement mechanism 8 is installed on the top of the stabilizing body 1 in conjunction with the second rotating shaft 801 of the stabilizing seat 6, so that the drive bevel gear and the driven bevel gear mesh. The construction personnel install the water tank 701 and the diversion pipe 702 on the stabilizing body 1, so that the two ends of the diversion pipe 702 are connected to the diversion seat respectively. A small water pump is installed between the water tank 701 and the diversion pipe 702. The small water pump, together with the diversion pipe 702, transports the water in the water tank 701 to the inside of the rotor, the rotating sleeve 302, and the first rotating shaft 304. At this time, the water flow dissipates heat from the rotor, the rotating sleeve 302, and the first rotating shaft 304.

[0057] Construction workers added coolant to the inside of water tank 701. With the help of the main body 1 and rollers, the construction workers moved the compaction device to the position of the civil foundation compaction. Then, the electric motor 301 was started. At this time, the compaction plate 403 jumped up and down to compact the foundation.

[0058] The compaction force of the tamping plate 403 is adjusted according to the softness of the foundation. The construction workers rotate the threaded rod 404, so that the stabilizing frame 401 moves upward under force. The construction workers push the positioning block 503 and then apply a push-pull force to the positioning block 503. At this time, the extrusion seat 303 moves under force to adjust different steps. Different hammering forces of the tamping plate 403 are achieved according to different steps. The different hammering forces of the tamping plate 403 are set as simple mechanical adjustments.

[0059] When the foundation is repeatedly compacted at the same location, after the construction workers move the positioning plate, they push the positioning plate to adjust the displacement of bolt 2. At this time, the driving bevel gear and the driven bevel gear separate, and the compaction device is in a stable state to repeatedly press and hammer the foundation.
