Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and more particularly to a foundation compacting device for civil engineering. Background Art

[0002] Civil engineering is a general term for the science and technology of building various types of land engineering facilities. It refers to the materials and equipment used, as well as the technical activities such as surveying, design, construction, maintenance, and repair, as well as the objects of engineering construction. During civil engineering construction, compaction devices are needed to compact the foundation of the civil engineering project. The external force generated by the compaction device is used to squeeze and compact the foundation to increase the density and strength of the foundation soil. However, the existing foundation compaction device for civil engineering has the following deficiencies in the process of compacting the foundation: the foundation compaction device adopts a hydraulic press to drive the compaction plate to continuously compact the foundation through the hydraulic power of the hydraulic press. The hydraulic power of the hydraulic press drives the compaction plate to generate large vibrations when working. The vibrations are transmitted to the foundation compaction device through the foundation and the compaction plate, which can easily cause the hydraulic press on the foundation compaction device and the parts connected to the device to loosen, thereby reducing the stability of the foundation compaction device in compacting the foundation. Moreover, after the compaction plate descends to compact the foundation during the compaction process, the hydraulic press cannot drive the compaction plate to rise for buffering. The compaction plate is subjected to the counter-vibration force generated by the foundation, which causes the compaction plate to be easily deformed during the compaction process, thereby reducing the service life of the compaction plate.

[0009] The beneficial effects of the present invention are: 1. When the support frame at the upper end of the main machine is installed and connected with the hydraulic mechanism, the installation frame is supported in the middle of the upper end of the support frame by the front and rear support blocks. At the same time, the four plug-in blocks on the inner side of the side sealing plates on the left and right mounting mechanisms are plugged into the inner edge of the installation frame to improve the firmness of the side sealing plates installed on the outer edge of the installation frame. After the side sealing plates are installed, they are tightly abutted against the surface of the hydraulic press through the inner contact plates, which ensures the firm positioning of the hydraulic press inside the installation frame. 2. The bottom surface of the gasket at the connection position between the support rod and the support frame is in the same plane as the bottom surface of the support rod, ensuring that the support rod can be stably installed and supported on the upper surface of the support frame. It is locked with the bolts and, at the same time, the elastic extrusion of the spring is used to improve the vibration reduction effect of the support rod installed on the upper end of the support frame, and the vibration reduction effect of the installation frame and the internal hydraulic press is improved to prevent the vibration from causing a slight angular deviation of the hydraulic press, resulting in the inability to drive the hammer rod to perform vertical hammering work inside the compaction host, thereby reducing the compaction effect of the foundation; 3. When encountering an unstable foundation surface, the hydraulic mechanism, the surrounding frame and the internal tamping plate are installed horizontally on the foundation surface through the independent telescopic adjustment of the four supporting mechanisms, ensuring that the hydraulic mechanism can apply vertical hydraulic power to the tamping plate, avoiding the hydraulic power from tilting at an angle and failing to act vertically on the tamping plate, effectively improving the tamping effect of the tamping plate on the foundation; 4. The six branch rods set between the support foot and the external ring can disperse the generated vibration, reducing the effect of the tamping plate inside the enclosing frame transmitting the vibration to the support foot, thereby ensuring that the support foot can stably support the support frame and the hydraulic mechanism as a whole, reducing the shaking caused by vibration; 5. The tamping plate descends and drives the articulated shaft block to pull the lower ends of the linked support plates on both sides to move downward. At this time, the two sliding blocks connected to the upper ends of the linked support plates slide toward the middle of the spring rod. The elastic force applied by the spring rod can have a certain buffering effect on the tamping plate, and the hammer rod is reset through the spring rod to apply a reset elastic force to the two sliding blocks to slide outward, so that the two linked support plates are reset and linked, thereby driving the tamping plate to reset, avoiding the tamping plate from getting stuck inside the foundation and being unable to move out during the process of tamping the foundation.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings: Example 1: As attached Figure 1 To the attached Figure 3 As shown: The present invention provides a foundation compacting device for civil engineering, the structure of which includes a hydraulic mechanism D and a compacting main unit H. The hydraulic mechanism D is installed at the top middle end of the compacting main unit H. The hydraulic mechanism D includes a mounting frame d2, a hydraulic press d7, a support block d8, a hammer rod d4, and a mounting mechanism d5. A support block d8 is provided at the middle of the front end of the mounting frame d2, and the support block d8 is installed at the top of the compacting main unit H. The hydraulic press d7 is installed inside the mounting frame d2, and the bottom output end of the hydraulic press d7 is welded to the top of the hammer rod d4. The lower end of the hammer rod d4 is clearance-fitted and penetrates the middle end of the compacting main unit H. The inner end of the mounting mechanism d5 is installed on the side of the mounting frame d2, and the inner end of the mounting mechanism d5 conflicts with the hydraulic press d7 inside the mounting frame d2. The outer end of the mounting mechanism d5 is installed on the side end of the top of the compacting main unit H. Two mounting mechanisms d5 are provided and are symmetrically mounted on both sides of the edge of the mounting frame d2. At the same time, two support blocks d8 are provided, one at the front and the other ends of the mounting frame d2. Through the mounting mechanisms d5 on the left and right sides and the support blocks d8 at the front and the back ends, the mounting frame d2 can be stably supported and mounted on the top middle end of the tamping machine H. The compacting machine H includes a support frame h5, a threaded hole h3, a force-bearing mechanism h8, and a support mechanism h1. The outer ends of the support block d8 and the mounting mechanism d5 are both connected to the upper end of the support frame h5. The upper end of the support frame h5 is embedded with a threaded hole h3, and the outer end of the mounting mechanism d5 is threadedly connected to the inner part of the threaded hole h3. The outer end surface of the force-bearing mechanism h8 is connected to the lower end of the support mechanism h1, and the bottom of the support mechanism h1 is welded to the bottom of the support frame h5. The mounting frame d2 is installed in the middle of the upper end of the support frame h5. The support frame h5 is a rectangular structure, and has a threaded hole h3 embedded on both sides. The threaded holes h3 on both sides can improve the firmness of the installation connection between the support frame h5 and the installation mechanisms d5 on both sides; There are four supporting mechanisms h1, and they are arranged at four positions on the bottom of the supporting frame h5. At the same time, the four supporting frames h5 are supported and connected to the front and back sides of the edges of the force-bearing mechanism h8, so that the force-bearing mechanism h8 can be stably supported under the supporting frame h5 and on the foundation surface that needs to be compacted.

[0019] The mounting mechanism d5 includes a support rod d59, a bolt d56, a spring d52, a gasket d57, a side sealing plate d58, a plug-in block d51, and a contact plate d54. The bolt d56 is threadedly connected to the threaded hole h3 at the upper end of the support frame h5, and the outer end of the support rod d59 is fastened to the upper end of the support frame h5 by the bolt d56. The bolt d56 passes through the inside of the spring d52, and the spring d52 is fixed to the bottom of the outer end of the support rod d59. The bottom of the outer end of the support rod d59 is fitted with a gasket d57, the inner end of the support rod d59 is welded to the outer end surface of the side sealing plate d58, and the side sealing plate d58 is installed on the side of the mounting frame d2. The corner end of the inner side of the side sealing plate d58 is provided with a plug-in block d51, and the plug-in block d51 is plugged into the inside of the side of the mounting frame d2. The contact plate d54 is installed in the middle of the inner side of the side sealing plate d58, and the contact plate d54 conflicts with the surface of the hydraulic press d7. The gasket d57 is made of rubber and has good resilience. The gasket d57 is embedded in the bottom of the outer end of the support rod d59. The bottom surface of the gasket d57 and the bottom surface of the support rod d59 are in the same plane, ensuring that the support rod d59 can be stably installed and supported on the upper surface of the support frame h5. It is locked with the bolt d56 and elastically squeezed with the spring d52 to improve the vibration reduction effect of the support rod d59 installed on the upper end of the support frame h5, thereby improving the vibration reduction effect of the mounting frame d2 and the internal hydraulic press d7. There are four plug-in blocks d51, which are located at the four corner edges of the inner surface of the side sealing plate d58. The four plug-in blocks d51 are plugged into the inner edge of the mounting frame d2 to improve the firmness of the side sealing plate d58 being mounted on the outer edge of the mounting frame d2. The contact plate d54 has an arc-shaped structure and matches the surface of the hydraulic press d7, ensuring that the contact plate d54 can tightly contact the surface of the hydraulic press d7, thereby ensuring the firm positioning of the hydraulic press d7 installed inside the mounting frame d2, and preventing vibration from causing a slight angular deviation of the hydraulic press d7, resulting in the inability to drive the hammer rod d4 to perform vertical hammering work inside the compaction main unit H, thereby reducing the compaction effect of the foundation.

[0020] The specific usage and function of this embodiment are as follows: In the present invention, when compacting the foundation of a civil engineering project, the compacting main unit H and the hydraulic mechanism D are supported on the foundation surface by the four supporting mechanisms h1 on the outside of the compacting main unit H. At the same time, when the support frame h5 on the upper end of the compacting main unit H is installed and connected with the hydraulic mechanism D, the installation frame d2 is supported on the middle part of the upper end of the support frame h5 by the front and rear two supporting blocks d8. At the same time, the four plug-in blocks d51 on the inner sides of the side sealing plates d58 on the installation mechanisms d5 on the left and right sides are plug-connected with the inner edge of the installation frame d2, thereby improving the firmness of the side sealing plates d58 being installed on the outer edge of the installation frame d2. After the side sealing plates d58 are installed, they are tightly abutted against the surface of the hydraulic press d7 through the inner contact plates d54, thereby ensuring the firmness of the positioning of the hydraulic press d7 installed inside the installation frame d2. At the same time, the bottom surface of the gasket d57 at the connection position of the support rod d59 and the support frame h5 is in the same plane as the bottom surface of the support rod d59, ensuring that the support rod d59 can be stably installed and supported on the upper surface of the support frame h5, and locked with the bolt d56. At the same time, the elastic extrusion of the spring d52 is used to improve the vibration reduction effect of the support rod d59 installed on the upper end of the support frame h5, thereby improving the vibration reduction effect of the installation frame d2 and the internal hydraulic press d7, and avoiding vibration causing a slight angular deviation of the hydraulic press d7, resulting in the inability to drive the hammer rod d4 to perform vertical hammering work on the inside of the compaction host H, thereby reducing the compaction effect of the foundation. The hammer rod d4 is driven vertically by the work of the hydraulic press d7, and the hydraulic power is transmitted to the inside of the force-bearing mechanism h8, and the foundation is compacted through the force-bearing mechanism h8.

[0021] Example 2: As attached Figure 4 To the attached Figure 7 As shown: The force-bearing mechanism h8 includes a lower guide frame h86, a reinforcing support rod h88, a ball bearing h83, and a working mechanism h81. The lower guide frame h86 is fixedly mounted on the upper end of the working mechanism h81, and the middle portion of the outer side of the lower guide frame h86 is welded to the upper end of the reinforcing support rod h88. The lower end of the reinforcing support rod h88 is welded to the upper surface of the upper end of the working mechanism h81. The ball bearing h83 is embedded in the lower guide frame h86. The outer side of the working mechanism h81 is connected to the lower end of the support mechanism h1. The hammer rod d4 is located directly above the lower guide frame h86 and the working mechanism h81. Two reinforcing struts h88 are provided and are symmetrically installed between the left and right sides of the lower guide frame h86 and the upper end surface of the working mechanism h81. Both reinforcing struts h88 are installed at an inclined angle. The reinforcing struts h88 on both sides improve the firmness of the lower guide frame h86 installed on the upper end of the working mechanism h81, preventing the hammer rod d4 from repeatedly lifting and lowering and penetrating the lower guide frame h86, which may cause the installation of the lower guide frame h86 to become loose. Twelve balls h83 are provided, and three are grouped together, distributed in a ring-shaped array at four locations inside the lower guide frame h86. The twelve balls h83 can effectively improve the smoothness of the hammer rod d4 and the interior of the lower guide frame h86, avoiding collision and jamming of the hammer rod d4 during repeated lifting and penetration work inside the lower guide frame h86, and improving the effect of the hammer rod d4 in applying hydraulic power vertically to the working mechanism h81.

[0022] The working mechanism h81 includes a top cover 1d, an enclosing frame 1k, a rubber pad 1j, a tamping plate 1b, and a buffer mechanism 1c. The top cover 1d is fixedly mounted on the top of the enclosing frame 1k, and a lower guide frame h86 is mounted in the middle of the upper end of the top cover 1d. The lower end of the reinforcing support rod h88 is welded to the top surface of the top cover 1d. The tamping plate 1b is located at the lower end of the inner part of the enclosing frame 1k, and a rubber pad 1j is provided in the middle of the upper end of the tamping plate 1b. The lower end of the buffer mechanism 1c is fixed to the edge of the upper surface of the tamping plate 1b, and the upper end of the buffer mechanism 1c is fixedly mounted on the upper end of the inner part of the enclosing frame 1k. The hammer rod d4 is located directly above the rubber pad 1j in the middle of the upper end of the tamping plate 1b. A circular opening is provided in the middle of the upper end of the top cover 1d, and the circular opening on the top cover 1d is aligned with the circular hole inside the lower guide frame h86. This ensures that the hammer rod d4 can pass through the lower guide frame h86 and the top cover 1d and vertically act downward on the rubber pad 1j of the tamping plate 1b, so that the tamping plate 1b is hydraulically powered to compact the foundation. The rubber pad 1j prevents the hammer rod d4 from hard collision with the tamping plate 1b and causing damage. There are two buffer mechanisms 1c, which are symmetrically installed inside the enclosing frame 1k and on the upper surfaces of the two side edges of the tamping plate 1b. The two buffer mechanisms 1c can elastically lift and buffer the tamping plate 1b during the process of tamping the foundation, thereby preventing the tamping plate 1b from being deformed and damaged during long-term tamping of the foundation.

[0023] The buffer mechanism 1c includes a sliding block c9, a spring rod c4, a linkage support plate c7, and an articulated shaft block c2. The spring rod c4 is inserted into the interior of the sliding block c9 with a clearance fit and is fixedly mounted on the upper end of the interior of the enclosing frame 1k. The upper end of the linkage support plate c7 is connected to the inner axis of the sliding block c9, and the lower end of the linkage support plate c7 is hinged to the interior of the articulated shaft block c2. The bottom surface of the articulated shaft block c2 is welded to the upper surface of the edge of the tamping plate 1b. The two sliding blocks c9 and the linked support plate c7 are each provided with two, and the two sliding blocks c9 are slidably mounted on both sides of the spring rod c4 in opposite directions. At the same time, the lower ends of the two linked support plates c7 are hingedly connected to the inside of the hinge shaft block c2, so that the two linked support plates c7 are connected to form a "V"-shaped structure. When the tamping plate 1b is subjected to the hydraulic power applied by the hammer rod d4 to tamp the foundation, the tamping plate 1b drives the hinge shaft block c2 to pull the lower ends of the linked support plates c7 on both sides to move downward. At this time, the two sliding blocks c9 connected to the upper end of the linked support plate c7 slide toward the middle of the spring rod c4. The elastic force applied by the spring rod c4 can play a certain buffering role on the tamping plate 1b. When the hammer rod d4 is reset, the tamping plate 1b loses power. At this time, the spring rod c4 applies a reset elastic force to the two sliding blocks c9 to slide outward, so that the two linked support plates c7 are reset and linked, thereby driving the tamping plate 1b to reset, preventing the tamping plate 1b from getting stuck inside the foundation and being unable to move out during the process of tamping the foundation.

[0024] Among them, the support mechanism h1 includes an electric push rod h14, a support foot h12, an external ring h16, a branch rod h19, a connecting slider h17, and an elastic rod h13. The top of the electric push rod h14 is fixedly installed on the bottom edge of the support frame h5, and the lower end of the electric push rod h14 is welded to the upper end of the support foot h12. The support foot h12 is inserted into the external ring h16 with a clearance fit, and the inside of the external ring h16 is welded to the outer surface of the support foot h12 through the branch rod h19. The connecting slider h17 is installed on the side of the external ring h16, and the elastic rod h13 is inserted into the connecting slider h17 with a clearance fit. The connecting slider h17 is slidably installed on the surface of the enclosing frame 1k, and the elastic rod h13 is fixedly installed on the surface of the enclosing frame 1k. Six branch rods h19 are provided and distributed in a ring shape at the connection between the inner side of the outer ring h16 and the outer surface of the support leg h12. The branch rods h19 can disperse the generated vibration, reducing the effect of the tamping plate 1b inside the surrounding frame 1k transmitting the vibration to the support leg h12, thereby ensuring that the support leg h12 can stably support the support frame h5 and the hydraulic mechanism D as a whole, reducing the shaking caused by vibration. The elastic rod h13 is installed in a vertical orientation and maintains a vertical orientation between the supporting feet h12. The supporting feet h12 drive the connecting slider h17 to perform vertical elastic guidance on the elastic rod h13, so that the supporting feet h12 can be raised and lowered outside the enclosing frame 1k. When encountering an unstable foundation surface, the electric push rods h14 on the four supporting mechanisms h1 drive the supporting feet h12 to be telescopically adjusted, and the hydraulic mechanism D as a whole, the enclosing frame 1k and the tamping plate 1b inside are horizontally installed on the foundation surface, ensuring that the hydraulic mechanism D can apply vertical hydraulic power to the tamping plate 1b, avoiding the hydraulic power from tilting at an angle and failing to act vertically on the tamping plate 1b, and effectively improving the tamping effect of the tamping plate 1b on the foundation.

[0025] The specific usage and function of this embodiment are as follows: In the present invention, when the force-bearing mechanism h8 is placed on the foundation surface, the electric push rod h14 drives the support foot h12 to move up and down. At this time, the external ring h16 drives the connecting slider h17 to perform vertical elastic guidance on the elastic rod h13, so that the support foot h12 can move up and down outside the enclosing frame 1k. When encountering an unstable foundation surface, the four support mechanisms h1 are independently telescopically adjusted to horizontally install the hydraulic mechanism D as a whole, the enclosing frame 1k and the internal tamping plate 1b on the foundation surface, ensuring that the hydraulic mechanism D can apply vertical hydraulic power to the tamping plate 1b, avoiding the hydraulic power from tilting at an angle and failing to act vertically on the tamping plate 1b, effectively improving The tamping plate 1b has the effect of tamping the foundation. At the same time, the six branch rods h19 set between the support foot h12 and the external ring h16 can disperse the generated vibration, weakening the effect of the tamping plate 1b inside the enclosing frame 1k transmitting the vibration to the support foot h12, thereby ensuring that the support foot h12 can stably support the support frame h5 and the hydraulic mechanism D as a whole, reducing the shaking caused by vibration. During the tamping work, when the hammer rod d4 is driven down by the hydraulic press d7, the hammer rod d4 extends into the lower guide frame h86, and the reinforcement rods h88 on both sides of the lower guide frame h86 are used to improve the firmness of the lower guide frame h86 installed on the upper end of the working mechanism h81, avoiding the hammer rod d 4 When the lower guide frame h86 is repeatedly lifted and lowered through the work, the installation of the lower guide frame h86 becomes loose, and the twelve ball bearings h83 can effectively improve the smoothness of the hammer rod d4 and the lower guide frame h86, so as to avoid the hammer rod d4 from colliding and getting stuck when the lower guide frame h86 is repeatedly lifted and lowered through the work, and improve the effect of the hammer rod d4 on the vertical action of the hydraulic power on the working mechanism h81. The hammer rod d4 can act vertically downward on the rubber pad 1j of the tamping plate 1b through the lower guide frame h86 and the top cover 1d, so that the tamping plate 1b is subjected to the hydraulic power to tamp the foundation, and the rubber pad 1j can avoid the hardness between the hammer rod d4 and the tamping plate 1b. At this time, the spring rod c4 is used to apply a reset elastic force to the two sliding blocks c9 to slide outward, so that the two linked support plates c7 are reset and linked, thereby driving the tamping plate 1b to reset, avoiding the tamping plate 1b from getting stuck inside the foundation and being unable to move out during the process of tamping the foundation.
