Description

Technical Field

[0001] The invention relates to the technical field of construction engineering equipment, in particular to a construction engineering foundation compacting device. Background Art

[0002] In today's construction industry, foundation compaction is a key step in ensuring the overall quality and safety of buildings. With the acceleration of my country's urbanization process and the continuous advancement of infrastructure construction, various construction projects have sprung up, and the requirements for foundation compaction technology and equipment have also increased.

[0003] At present, the foundation compaction devices used in my country's construction projects can meet the basic construction needs to a certain extent, but in the actual application process, they still expose many problems that need to be solved: Imperfect dust suppression measures: During the foundation compaction process, a large amount of dust will be generated, which will not only cause serious pollution to the air quality of the construction site, but also pose a threat to the health of construction workers. Long-term exposure to high-concentration dust environments makes construction workers very likely to suffer from respiratory diseases, pneumoconiosis and other occupational diseases. Existing dust suppression measures, such as simple watering to suppress dust, have limited effects and cannot fundamentally solve the dust problem. They do not meet my country's requirements for green and environmentally friendly construction, and are not conducive to the occupational health protection of construction workers.

[0004] Single or missing crushing function: There are often obstacles of various types and sizes in the foundation, such as stones, hard soil blocks, and construction waste, as well as soils of different shapes. Most foundations are uneven, resulting in poor surface flatness, affecting the subsequent construction quality and failing to meet the construction requirements under complex foundation conditions. This not only increases the workload and cost of manual processing, but may also pose safety hazards due to incomplete foundation processing.

[0005] In summary, the existing construction engineering foundation compaction device has deficiencies in dust reduction effect and crushing function. Therefore, in order to ensure good dust reduction effect, powerful crushing function and high coordination function in the foundation compaction process, a construction engineering foundation compaction device is proposed. Summary of the invention

[0006] The present invention aims to provide a construction engineering foundation compaction device to solve the problems of imperfect dust reduction measures and single crushing function in the prior art.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The specific implementation process is as follows: Embodiment 1: See also Figure 1-6The present invention provides a technical solution: a construction engineering foundation compaction device, including a body 1, a moving wheel 2 is installed under the body 1, a compaction groove 3 is opened at one end of the inner wall of the body 1, compaction slide grooves 301 are opened on both sides of the inner wall of the compaction groove 3, the compaction groove 3 is movably adapted to the compaction hammer 705, the compaction slide groove 301 is movably embedded and adapted to the lifting slide plate 708, a spray device 4 is fixedly installed in the middle of the inner wall of the body 1, the spray device 4 is mainly used for dust reduction and increasing soil viscosity during construction, the spray device 4 includes a negative pressure airbag 401 fixedly installed at one end of the lifting slide plate 708, when the compaction hammer 705 drives the lifting slide plate 708 to move up and down in the compaction slide groove 301, the movement of the lifting slide plate 708 synchronously drives the negative pressure airbag 401 to move up and down The up and down movement of the negative pressure airbag 401 changes the air pressure inside it, thereby generating negative pressure suction. A negative pressure tank 402 is fixedly installed below the negative pressure tank 401, a water inlet pipe 403 is fixedly installed below the negative pressure tank 402, a water outlet pipe 404 is fixedly installed on one side of the negative pressure tank 402, and a plurality of water distribution pipes 405 are evenly distributed on one end of the water outlet pipe 404. Under the action of negative pressure suction, the water source in the water tank 407 is sucked into the negative pressure tank 402 through the water inlet pipe 403, and then discharged through the water outlet pipe 404. Atomizing nozzles 406 are installed on one end of the water distribution pipes 405. These atomizing nozzles 406 have a specific inclination angle, which faces the position facing the crushing roller 808. When water passes through the atomizing nozzles 406, it will be atomized into fine water droplets and sprayed out, which has a great impact on the crushing. The device 8 performs dust reduction treatment on the dust generated by the crushing work, and at the same time increases the soil viscosity after the crushing is completed, creating better conditions for the subsequent compaction work. One end of the water outlet pipe 404 is fixedly connected to a water tank 407, and the water tank 407 is fixedly installed in the middle of the inner wall of the body 1. A water filling port 408 is fixedly installed above the water tank 407, and a cover plate 409 is installed above the water tank 407. A transmission groove 5 is opened at the other end of the inner wall of the body 1, and transmission slide grooves 501 are opened on both sides of the inner wall of the transmission groove 5.

The transmission slide plate 503 is fixedly connected to both ends of the first crushing rod 801. The extension and retraction of the hydraulic rod 502 is controlled by a control device, which can drive the transmission slide plate 503 to move in a certain direction. The transmission slide 501 moves up and down, thereby realizing the precise adjustment of the overall height of the crushing device 8 to adapt to different construction conditions and foundation conditions. A transmission device 6 is fixedly installed above the tamping groove 3. The transmission device 6 is the power transmission core of the entire device. The transmission device 6 includes a transmission motor 601 fixedly installed above the body 1. The transmission motor 601 serves as a power source. A transmission gear 602 and a transmission shaft 604 are fixedly installed at the output end of the transmission motor 601. When the transmission motor 601 starts to run, the rotational power of the motor is directly transmitted to the transmission gear 602 and the transmission shaft 604, so that they rotate synchronously. A rotating shaft 603 is movably installed between the transmission gear 602 and the transmission shaft 604, and a transmission rod 605 is symmetrically installed on the side of the transmission shaft 604.The transmission rod 605 performs circular motion as the transmission shaft 604 rotates, providing power input for the subsequent tamping device 7. The tamping device 7 is movably embedded in the tamping groove 3. The tamping device 7 is responsible for the actual tamping operation of the foundation. The tamping device 7 includes a rotating plate 701 fixedly installed on the side of the rotating shaft 603. The rotating plate 701 rotates as the rotating shaft 603 rotates. A rotating rod 702 is fixedly installed at one end of the rotating plate 701. During the rotation of the transmission rod 605, the transmission rod 605 will periodically contact the rotating rod 702, and transmit the rotational power of the transmission shaft 604 to the rotating rod 702, driving the rotating rod 702 to rotate around its axis. A connecting plate 703 is fixedly installed at one end of the rotating rod 702. The connecting plate 703 A buffer damping rod 704 is fixedly installed at the bottom, and a tamping hammer 705 is fixedly installed at the bottom of the buffer damping rod 704. The rotation of the rotating rod 702 causes the connecting plate 703 to perform a unique axial rotation and movement up and down. This composite movement is transmitted to the tamping hammer 705 through the buffer damping rod 704 fixedly connected at the bottom of the connecting plate 703, so that the tamping hammer 705 moves up and down regularly in the tamping groove 3. A tamping plate 706 is fixedly installed at the bottom of the tamping hammer 705. The tamping plate 706 and the tamping hammer 705 are fixedly connected by a tamping spring 707. The tamping spring 707 plays a role in buffering and enhancing the tamping strength during the tamping process. A lifting slide 708 is fixedly installed on the side of the tamping hammer 705. The lifting slide 708 ensures that the tamping hammer 705 can move up and down regularly. In order to ensure the stability and accuracy during the movement, a crushing device 8 is installed under the transmission groove 5. The crushing device 8 is used to crush the uneven soil, stones and other debris in the foundation to ensure the flatness of the foundation surface. The crushing device 8 includes a first crushing rod 801 fixedly installed on the inner wall of the transmission groove 5, a crushing gear 802 is movably installed on the surface of the first crushing rod 801, and a transmission belt 803 is installed on the surface of the crushing gear 802. The other end of the transmission belt 803 is adapted to be connected with the transmission gear 602. When the transmission motor 601 is running, it drives the transmission gear 602 at the output end to rotate, and the rotation of the transmission gear 602 is transmitted to the crushing gear 802 through the transmission belt 803, so that the crushing gear 802 rotates around the first crushing rod 801. A crushing plate 804 is symmetrically installed on the surface of the rod 801, and a driven rod 805 is fixedly installed below the crushing plate 804. A driven gear 806 is movably installed on the surface of the driven rod 805. A driven belt 807 is adapted to be installed on the surface of the driven gear 806. When the crushing gear 802 rotates, the driven belt 807 also rotates accordingly. The rotation of the driven belt 807 drives the driven gear 806 to rotate. The other end of the driven belt 807 is adapted to be connected with the crushing gear 802. A crushing roller 808 is fixedly installed on one side of the driven gear 806. The rotation of the driven gear 806 eventually drives the crushing roller 808 to rotate at a high speed. During the rotation process, the crushing roller 808 can crush uneven soil and debris to achieve a relatively consistent flatness, which is convenient for subsequent compaction work. First, firmly install the moving wheel 2 at the four corner positions below the machine body 1 to ensure that the moving wheel 2 can rotate freely and the support is stable, so that the device has good mobility. Next, install the transmission motor 601 above the machine body 1, and accurately fix the transmission gear 602 and the transmission shaft 604 at the output end of the transmission motor 601. Flexibly install the rotating shaft 603 between the transmission gear 602 and the transmission shaft 604 to ensure that it can rotate freely.

Install the tamping device 7 in the tamping groove 3, firmly fix the rotating plate 701 on the side of the rotating shaft 603 to ensure that the rotating plate 701 can As the rotating shaft 603 rotates synchronously, one end of the rotating rod 702 is fixed on the rotating plate 701, and the other end is fixedly connected to the connecting plate 703. A buffer damping rod 704 is installed under the connecting plate 703, and a tamping hammer 705 is fixed to the lower end of the buffer damping rod 704. The tamping plate 706 is connected to the tamping hammer 705 through a tamping spring 707 to ensure that the tamping spring 707 has suitable elasticity and buffering performance. A lifting slide 708 is installed on the side of the tamping hammer 705. At the same time, tamping grooves 301 compatible with the lifting slide 708 are opened on both sides of the inner wall of the tamping groove 3, so that the lifting slide 708 can slide up and down smoothly in the tamping groove 301, and the negative pressure airbag 401 is fixedly installed at one end of the lifting slide 708 to ensure that the negative pressure airbag The bag 401 can move synchronously with the up and down movement of the lifting slide plate 708. The negative pressure tank 402 is connected below the negative pressure air bag 401, and one end of the water inlet pipe 403 is connected to the negative pressure tank 402, and the other end is connected to the water tank 407. The water outlet pipe 404 is connected to one side of the negative pressure tank 402, and the water distribution pipe 405 is evenly distributed at one end of the water outlet pipe 404. An atomizing nozzle 406 with an inclined angle is installed at the end of the water distribution pipe 405. The water tank 407 is fixedly installed in the middle position of the inner wall of the body 1, and a water filling port 408 is opened above the water tank 407, and a cover plate 409 is covered. Sufficient clean water is injected into the water tank 407 through the water filling port 408. The crushing device 8 is installed in the transmission groove 5, and the first crushing rod 801 is fixedly installed in the transmission groove. 5, ensure that it is stable and reliable, install the crushing gear 802 movably on the surface of the first crushing rod 801, put one end of the transmission belt 803 on the transmission gear 602, and the other end on the crushing gear 802, ensure that the tension of the transmission belt 803 is appropriate and can accurately transmit power, install the driven belt 807 on the surface of the crushing gear 802, and put the other end of the driven belt 807 on the driven gear 806, and fix the crushing roller 808 on one side of the driven gear 806 to ensure that the crushing roller 808 can rotate at high speed with the rotation of the driven gear 806, open the transmission slide groove 501 on both sides of the inner wall of the transmission groove 5, fix the hydraulic rod 502 in the transmission slide groove 501, and connect the transmission slide plate 503 with one end of the hydraulic rod 502.And fix the transmission slide 503 to both ends of the first crushing rod 801 to ensure that the hydraulic rod 502 can smoothly drive the crushing device 8 to move up and down through the transmission slide 503. Finally, check whether the connection of each component is firm, whether the rotation of the transmission component is smooth, and whether the electrical circuit is connected correctly to ensure that the device is in good operating condition before starting.

[0019] Working principle: according to the construction requirements, the machine body 1 is pushed, and the device is moved to the designated foundation compaction position by the moving wheel 2. Through manual adjustment or with the help of auxiliary equipment, the device is accurately aligned with the foundation area to be processed to ensure the accuracy of subsequent work. The transmission motor 601 is started, and the transmission motor 601 starts to operate. The output power drives the transmission shaft 604 and the transmission gear 602 to rotate synchronously. The rotation of the transmission shaft 604 drives the transmission rod 605 on its side to perform circular motion. During the rotation of the transmission rod 605, the transmission rod 605 periodically contacts the rotating rod 702, and the rotational power is transmitted to the rotating rod 702. The rotating rod 702 drives the connecting plate 703 to rotate up and down on the axis. This composite motion is transmitted to the tamping hammer 705 through the buffer damping rod 704, so that the tamping hammer 705 reciprocates up and down in the tamping groove 3. The tamping plate 706 under the tamping hammer 705 is under the action of the tamping spring 707. The foundation surface is powerfully compacted. 05 During the up and down movement, the lifting slide 708 slides up and down synchronously along the tamping chute 301, ensuring the stability and accuracy of the tamping work. As the tamping hammer 705 moves up and down, the lifting slide 708 also moves up and down, thereby driving the negative pressure airbag 401 fixed thereon to move up and down. The up and down movement of the negative pressure airbag 401 changes the air pressure inside it, generating negative pressure suction. Under the action of the negative pressure suction, the water in the water tank 407 is sucked into the negative pressure groove 402 through the water inlet pipe 403, and then enters the atomizing nozzle 406 through the water outlet pipe 404 and the water distribution pipe 405. The atomizing nozzle 406 atomizes the water into fine water droplets, which are sprayed to the position of the crushing roller 808 at a set inclination angle. These atomized water droplets can not only effectively suppress the flying dust generated by the crushing work of the crushing device 8, reduce the dust concentration at the construction site, and improve the construction environment, but also increase the viscosity of the crushed soil, so that the soil particles are better combined together, providing better conditions for subsequent tamping work.

[0020] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
