Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of foundation leveling, in particular to a foundation leveling equipment for construction engineering. BACKGROUND

[0002] In construction engineering, foundation leveling is the basic work to ensure the stability of building structure. Foundation leveling equipment is used to remove, compact and level the ground surface in order to provide stable and uniform support for the foundation of the building. Bulldozer is the most common equipment used for foundation leveling. It pushes the soil flat or removes it through the large shovel in front. Bulldozer is usually used to clean up large area of land, adjust the terrain to make it flat, but it cannot achieve large-scale foundation leveling, and the leveling effect is poor; the foundation leveling equipment in the prior art usually has poor leveling effect and cannot realize full-automatic operation, which is inconvenient to use. SUMMARY

[0003] In view of the above technical problems, the technical scheme adopted by the present application is as follows: a foundation leveling equipment for construction engineering, comprising a base mechanism for moving and watering, the base mechanism comprising a frame body, a watering module is arranged on the frame body, a flattening mechanism for leveling the foundation and a soil compacting mechanism for preliminary soil compaction are arranged on the base mechanism, the flattening mechanism comprises a ground pressing box, the soil compacting mechanism comprises an adjusting arm, and a ratchet gear is rotatably installed on the adjusting arm;

[0004] The flattening mechanism comprises a lifting rod and a center column which are slidingly installed on the ground pressing box, a pressing plate is fixedly installed on the center column, a lifting block is fixedly installed on the center column, a guide column is fixedly installed on the lifting block, the guide column slides on the ground pressing box, a driving wheel is rotatably installed on the ground pressing box, and the driving wheel is in contact with the guide column.

[0005] Further, the base mechanism comprises a traveling wheel which is rotatably installed on the frame body, a traveling track is wound outside the traveling wheel, and a motor for driving the traveling wheel is arranged in the frame body.

[0006] Further, the watering module comprises a piston cylinder which is fixedly installed on the ground pressing box, a water tank is fixedly installed on the frame body, the water tank is communicated with the piston cylinder through a push-out pipe, two spray pipes are fixedly installed on the water tank, a plurality of spray heads are arranged on the spray pipes, the lifting rod is slidingly installed with the piston cylinder, a piston sheet is fixedly installed on the piston cylinder, the piston sheet slides along the inner wall of the piston cylinder, and a one-way rotating sheet is rotatably installed on the piston cylinder.

[0007] The traveling wheel is driven to rotate by the two motors in the frame body, so as to drive the traveling track to rotate, so that the whole equipment moves and turns.

[0008] When the lifting rod rises, it drives the piston plate to slide upward along the piston cylinder. At this time, the one-way vane closes, pushing the gas above the piston plate into the water tank through the ejector pipe. The water in the tank is then sprayed out from the nozzles of the spray pipe to clean the tracks. At the same time, the wet tracks moisten the foundation soil, making it easier to press. When the lifting rod descends, the piston plate slides downward along the piston cylinder. The negative pressure causes the one-way vane to rotate inward, allowing outside gas to enter the piston cylinder. This process repeats continuously, ensuring that the water in the tank is continuously sprayed out from the nozzles of the spray pipe.

[0009] Furthermore, the flattening mechanism also includes a flattening motor fixedly installed on the flattening box. The flattening motor drives the dial wheel to rotate via a transmission belt. The pressure plate and the lifting rod are fixedly installed. A tension spring is provided between the lifting block and the flattening box. A rack frame is fixedly installed on the lifting rod. A ratchet is slidably installed on the rack frame. A spring is provided between the ratchet and the rack frame. The ratchet meshes with the ratchet gear.

[0010] Furthermore, two outer rotating blocks are rotatably installed inside the ground pressing box. A sliding sleeve is fixedly installed on the outer rotating block. A sliding rod is slidably installed inside the sliding sleeve. An inner rotating block is fixedly installed on the sliding rod. The inner rotating block is rotatably installed with the lifting block. A spring is provided between the sliding rod and the sliding sleeve.

[0011] The flattening motor drives the dial wheel to rotate via a transmission belt. The dial wheel drives the lifting block, center column, pressure plate, and lifting rod to rise via a guide column. The lifting rod drives the rack and pinion frame and ratchet rack to rise, stretching the tension spring. At the same time, the inner rotating block rotates relative to the lifting block, and the outer rotating block rotates relative to the ground pressing box. The sliding rod slides relative to the sliding sleeve, and the spring between the sliding sleeve and the sliding rod is compressed. Then the dial wheel disengages from the guide column, the tension spring rebounds, and the spring between the sliding sleeve and the sliding rod rebounds, causing the lifting block, pressure plate, center column, lifting rod, rack and pinion frame, and ratchet rack to descend rapidly. The pressure plate flattens the foundation. The dial wheel has two blades, which cause the pressure plate to rise and fall continuously, achieving high-frequency flattening of the foundation.

[0012] Furthermore, the soil compaction mechanism includes a pressure arm rotatably mounted on an adjusting arm, a counterweight block rotatably mounted on the pressure arm, a lever rotatably mounted on the adjusting arm, a lever fixedly mounted on the lever, and the lever cooperating with the pressure arm.

[0013] Furthermore, a worm gear is fixedly mounted on the ratchet gear, and a worm wheel is rotatably mounted on the frame. The worm gear meshes with the worm wheel, and the worm wheel drives the lever to rotate through gear transmission and belt transmission.

[0014] Furthermore, the frame is provided with an adjustment module, which includes a lower rotating seat rotatably mounted on the frame, a rotating ring rotatably mounted on the adjustment arm, a lead screw fixedly mounted on the lower rotating seat, the lead screw slidingly mounted on the rotating ring, a strong spring between the rotating ring and the lower rotating seat, an internal thread block rotatably mounted on the rotating ring, the internal thread block having an internal thread, and the internal thread block and the lead screw forming a threaded transmission.

[0015] When it is necessary to adjust the angle between the adjusting arm and the frame, the rotatable internal thread block causes the swivel to slide along the screw. In the initial state, the strong spring is in a compressed state. As the swivel slides along the screw, the strong spring rebounds to a certain extent or is further compressed. At this time, the lower swivel rotates relative to the frame, the swivel rotates relative to the adjusting arm, and the angle between the adjusting arm and the frame changes to adapt to more working environments.

[0016] When the lifting rod descends, the ratchet rack drives the ratchet gear and worm gear to rotate, which in turn drives the worm wheel to rotate. Through gear transmission and belt transmission, the lever rotates counterclockwise, which in turn drives the lever to rotate. When the lever contacts the pressure arm, it drives the pressure arm to rotate relative to the adjusting arm, which in turn drives the counterweight block to rise. The counterweight block has a large weight and always keeps its bottom surface facing down. When the lever disengages from the pressure arm, the counterweight block drives the pressure arm to rotate under its own weight. The counterweight block hammers the foundation, initially flattening the foundation. When the equipment moves, the counterweight block first initially flattens the foundation, and then the pressure plate achieves high-frequency precision flattening of the foundation.

[0017] The beneficial effects of this invention compared with the prior art are: (1) The water spraying module set in this invention can clean the walking track when leveling the foundation, and the wet walking track can wet the foundation soil, which is convenient for pressing; (2) The pressing mechanism set in this invention uses multiple sets of springs in conjunction with the cooperation of the dial wheel and the guide column to enable the pressing plate to hit the foundation at a high frequency, thus achieving efficient foundation leveling operation; (3) When the pressing plate set in this invention is pressing the foundation, it will also drive the pressing arm to lift, thereby pre-pressing the foundation at the front of the equipment through the counterweight pressing block, which is convenient for leveling the foundation when the pressing plate reaches the pre-pressing point, thus improving the leveling effect.

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example: Reference Figures 1-8 A foundation leveling device for construction engineering includes a base mechanism for movement and water spraying. The base mechanism includes a frame 101, on which a water spraying module is installed. The base mechanism is equipped with a leveling mechanism for leveling the foundation and a soil compaction mechanism for preliminary soil compaction. The leveling mechanism includes a soil compaction box 201, and the soil compaction mechanism includes an adjusting arm 301, on which a ratchet 307 is rotatably mounted.

[0029] The flattening mechanism includes a lifting rod 204 and a central column 206 slidably mounted on the flattening box 201. A pressure plate 205 is fixedly mounted on the central column 206. A lifting block 210 is fixedly mounted on the central column 206. A guide column 211 is fixedly mounted on the lifting block 210. The guide column 211 slides on the flattening box 201. A dial 203 is rotatably mounted on the flattening box 201. The dial 203 is in contact with the guide column 211.

[0030] likeFigure 2 , Figure 3 As shown, the base mechanism includes a traveling wheel 102 rotatably mounted on the frame 101, a traveling track 109 wrapped around the traveling wheel 102, and a motor for driving the traveling wheel 102 is provided inside the frame 101.

[0031] like Figure 2 , Figure 3 As shown, the sprinkler module includes a piston cylinder 106 fixedly installed on the ground pressure box 201, a water tank 103 fixedly installed on the frame 101, the water tank 103 and the piston cylinder 106 are connected through the push-out pipe 105, two spray pipes 104 are fixedly installed on the water tank 103, and several nozzles are provided on the spray pipes 104. The lifting rod 204 is slidably installed on the piston cylinder 106, a piston plate 108 is fixedly installed on the piston cylinder 106, the piston plate 108 slides along the inner wall of the piston cylinder 106, and a one-way rotating plate 107 is rotatably installed on the piston cylinder 106, the one-way rotating plate 107 can only rotate inward.

[0032] Two motors inside the frame 101 drive the walking wheels 102 to rotate, which in turn drives the walking tracks 109 to rotate, enabling the equipment to move and turn as a whole.

[0033] When the lifting rod 204 rises, it drives the piston plate 108 to slide upward along the piston cylinder 106. At this time, the one-way rotating plate 107 closes, pushing the gas above the piston plate 108 into the water tank 103 through the push-out pipe 105. The water in the water tank 103 is sprayed out from the nozzle of the spray pipe 104 to clean the walking track 109. At the same time, the wet walking track 109 can wet the foundation soil, which is convenient for compaction. When the lifting rod 204 descends, the piston plate 108 slides downward along the piston cylinder 106. The negative pressure causes the one-way rotating plate 107 to rotate inward, and the outside gas enters the piston cylinder 106. This process is repeated to continuously spray the water in the water tank 103 out from the nozzle of the spray pipe 104.

[0034] like Figure 4 , Figure 5 As shown, the flattening mechanism also includes a flattening motor 202 fixedly installed on the flattening box 201. The flattening motor 202 drives the dial wheel 203 to rotate via a transmission belt. The pressure plate 205 is fixedly installed with the lifting rod 204. A tension spring 209 is provided between the lifting block 210 and the flattening box 201. A rack frame 207 is fixedly installed on the lifting rod 204. A ratchet rack 208 is slidably installed on the rack frame 207. A spring is provided between the ratchet rack 208 and the rack frame 207. The ratchet rack 208 meshes with the ratchet gear 307.

[0035] like Figure 4 , Figure 5As shown, two outer rotating blocks 212 are rotatably installed inside the ground pressing box 201. A sliding sleeve 214 is fixedly installed on the outer rotating block 212. A sliding rod 215 is slidably installed inside the sliding sleeve 214. An inner rotating block 213 is fixedly installed on the sliding rod 215. The inner rotating block 213 is rotatably installed with the lifting block 210. A spring is provided between the sliding rod 215 and the sliding sleeve 214.

[0036] The flattening motor 202 drives the dial wheel 203 to rotate via a transmission belt. The dial wheel 203 drives the lifting block 210, the center column 206, the pressure plate 205, and the lifting rod 204 to rise via the guide column 211. The lifting rod 204 drives the rack frame 207 and the ratchet rack 208 to rise, and the tension spring 209 is stretched. At the same time, the inner rotating block 213 rotates relative to the lifting block 210, the outer rotating block 212 rotates relative to the pressing box 201, and the sliding rod 215 slides relative to the sliding sleeve 214. The spring between the slide bar 215 and the slide 4 is compressed, and then the dial wheel 203 disengages from the guide post 211, the tension spring 209 rebounds, and the spring between the slide sleeve 214 and the slide bar 215 rebounds, causing the lifting block 210, pressure plate 205, center post 206, lifting rod 204, rack frame 207, and ratchet 208 to descend rapidly. The pressure plate 205 flattens the foundation. The dial wheel 203 has two blades, which cause the pressure plate 205 to rise and fall continuously, achieving high-frequency flattening of the foundation.

[0037] like Figures 6-8 As shown, the soil compaction mechanism includes a pressure arm 302 rotatably mounted on an adjusting arm 301, a counterweight block 303 rotatably mounted on the pressure arm 302, a lever 304 rotatably mounted on the adjusting arm 301, and a lever 305 fixedly mounted on the lever 304, which cooperates with the pressure arm 302.

[0038] like Figures 6-8 As shown, a worm gear 306 is fixedly mounted on the ratchet gear 307, and a worm wheel 308 is rotatably mounted on the frame 101. The worm gear 306 meshes with the worm wheel 308, and the worm wheel 308 drives the lever 304 to rotate through gear transmission and belt transmission.

[0039] like Figures 6-8 As shown, an adjustment module is provided on the frame 101. The adjustment module includes a lower rotating seat 310 rotatably mounted on the frame 101, a rotating ring 309 rotatably mounted on the adjustment arm 301, a lead screw 311 fixedly mounted on the lower rotating seat 310, the lead screw 311 and the rotating ring 309 being slidably mounted, a strong spring 313 being provided between the rotating ring 309 and the lower rotating seat 310, and an internal thread block 312 rotatably mounted on the rotating ring 309. The internal thread block 312 is provided with internal threads, and the internal thread block 312 and the lead screw 311 form a threaded transmission.

[0040] When it is necessary to adjust the angle between the adjusting arm 301 and the frame 101, the rotatable internal thread block 312 causes the swivel ring 309 to slide along the lead screw 311. In the initial state, the strong spring 313 is in a compressed state. As the swivel ring 309 slides along the lead screw 311, the strong spring 313 rebounds to a certain extent or is further compressed. At this time, the lower swivel seat 310 rotates relative to the frame 101, the swivel ring 309 rotates relative to the adjusting arm 301, and the angle between the adjusting arm 301 and the frame 101 changes to adapt to more working environments.

[0041] When the lifting rod 204 descends, the ratchet rack 208 drives the ratchet gear 307 and the worm gear 306 to rotate, which in turn drives the worm wheel 308 to rotate. Through gear transmission and belt transmission, the lever 304 is driven to rotate counterclockwise, which in turn drives the lever 305 to rotate. When the lever 305 contacts the pressure arm 302, it drives the pressure arm 302 to rotate relative to the adjusting arm 301, which in turn drives the counterweight block 303 to rise. The counterweight block 303 has a large weight and always keeps its bottom surface facing down. When the lever 305 disengages from the pressure arm 302, the counterweight block 303 drives the pressure arm 302 to rotate under its own weight. The counterweight block 303 hammers the foundation to initially flatten the foundation. When the equipment moves, the counterweight block 303 first initially flattens the foundation, and then the pressure plate 205 achieves high-frequency precision flattening of the foundation.

[0042] The working principle of the foundation leveling equipment for building engineering disclosed in this invention is as follows: the two motors in the frame 101 drive the walking wheels 102 to rotate, thereby driving the walking track 109 to rotate, so that the equipment moves and turns as a whole. The flattening motor 202 drives the dial wheel 203 to rotate via a transmission belt. The dial wheel 203 drives the lifting block 210, the center column 206, the pressure plate 205, and the lifting rod 204 to rise via the guide post 211. The lifting rod 204 drives the rack frame 207 and the ratchet 208 to rise, stretching the tension spring 209. At the same time, the inner rotating block 213 rotates relative to the lifting block 210, and the outer rotating block 212 rotates relative to the pressing box 201. The sliding rod 215 slides relative to the sliding sleeve 214, compressing the spring between the sliding sleeve 214 and the sliding rod 215. Subsequently, the dial wheel 203 disengages from the guide post 211, the tension spring 209 rebounds, and the spring between the sliding sleeve 214 and the sliding rod 215 rebounds, causing the lifting block 210, the pressure plate 205, the center column 206, the lifting rod 204, the rack frame 207, and the ratchet 208 to descend rapidly. When the lifting rod 204 descends, the ratchet rack 208 drives the ratchet gear 307 and the worm gear 306 to rotate, which in turn drives the worm wheel 308 to rotate. Through gear transmission and belt transmission, the lever 304 is driven to rotate counterclockwise, which in turn drives the lever 305 to rotate. When the lever 305 contacts the pressure arm 302, it drives the pressure arm 302 to rotate relative to the adjusting arm 301, which in turn drives the counterweight block 303 to rise. The counterweight block 303 has a large weight and always keeps its bottom surface facing down. When the lever 305 disengages from the pressure arm 302, the counterweight block 303 drives the pressure arm 302 to rotate under its own weight. The counterweight block 303 hammers the foundation to initially flatten the foundation. The pressure plate 205 flattens the foundation. The lever 203 has two blades, which make the pressure plate 205 rise and fall continuously, achieving high-frequency flattening of the foundation. When the equipment is moved, the counterweight block 303 first flattens the foundation, and then the pressure plate 205 achieves high-frequency precision flattening of the foundation.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
