Description

TECHNICAL FIELD

[0001] The application relates to the technical field of engineering construction, in particular to a foundation dynamic compaction reinforcement device. BACKGROUND

[0002] The dynamic compaction method is also known as the dynamic compaction method, and is also known as the dynamic consolidation method. The dynamic compaction method is to use a large crawler-type dynamic compactor to drop a 8-30 ton weight from a height of 6-30 meters freely to compact the soil, rapidly improve the bearing capacity and compression modulus of the foundation, and form a relatively uniform and dense foundation, and change the pore distribution of the foundation soil within a certain depth of the foundation.

[0003] The existing patent (publication number: CN216142024U) discloses a foundation dynamic compaction reinforcement device, which comprises a dynamic compactor, a mounting bracket, an unhooking device and a dynamic compactor hammer. The unhooking device is hung below the mounting bracket of the dynamic compactor, the unhooking device is controlled by the unhooking cable of the dynamic compactor, and the unhooking device is provided with a trolley for fixing the dynamic compactor hammer; when the dynamic compactor hammer needs to be lowered, the dynamic compactor pulls the unhooking cable, and the two trolleys in the unhooking device are driven to move in opposite directions by the unhooking cable. The dynamic compactor hammer is no longer clamped, and at this time the dynamic compactor hammer is not limited to free falling and compacts the ground; after the dynamic compactor hammer falls, the dynamic compactor controls the unhooking device to descend, and relaxes the unhooking cable, so that the trolley is restored under the action of the spring, the dynamic compactor hammer is clamped into the unhooking device again, and then the dynamic compactor hammer is lifted, and the next dynamic compaction operation can be performed. The foundation dynamic compaction reinforcement device can automatically hook and unhook the dynamic compactor hammer, thereby improving the efficiency and safety of the dynamic compaction operation.

[0004] In the above-mentioned comparative document, the unhooking cable is used to move the two trolleys in opposite directions, so as to release the limiting effect of the dynamic compactor hammer. However, the unhooking cable is prone to breakage when it is forced, and when the dynamic compactor hammer is clamped in the equipment cabin, no limiting component is arranged below, so that the dynamic compactor hammer may shake up and down during the lifting process. In order to solve the above-mentioned problems, a foundation dynamic compaction reinforcement device is provided. Practical new type content

[0005] In view of the deficiencies of the prior art, the application provides a foundation dynamic compaction reinforcement device which can quickly and stably make the dynamic compactor hammer fall and compact the land, and can also make the dynamic compactor hammer and the equipment be more stably clamped.

[0006] To achieve the above object, the application provides the following technical scheme: A ground foundation strong ramming reinforcement equipment, comprising an equipment cabin, a strong ramming hammer and a clamping mechanism, the equipment cabin and the strong ramming hammer are clamped through the clamping mechanism, the clamping mechanism comprises a buffer base fixedly connected to the upper surface of the strong ramming hammer, a limiting sleeve fixedly connected to the outer surface of the buffer base, and a semicircular block fixedly connected to the top end of the buffer base, the inside of the buffer base is provided with a partition plate, the two sides of the partition plate are fixedly connected with small air cylinders, the output ends of the two small air cylinders are fixedly connected with push plates, the inner wall of the equipment cabin is fixedly connected with two sliding grooves, the inner wall of each sliding groove is slidingly connected with a wedge-shaped block, the side away from each other of the two wedge-shaped blocks is fixedly connected with first extension springs, and the ends away from each other of the two first extension springs are fixedly connected with the inner walls of the two sliding grooves.

[0007] Through the above scheme, the wedge-shaped block can be clamped between the semicircular block and the limiting sleeve through the limiting sleeve, so that the buffer base cannot shake up and down during the lifting of the strong ramming hammer following the equipment cabin, and the strong ramming hammer can be clamped in the equipment cabin more stably, the wedge-shaped block can be quickly and stably pushed into the sliding groove through the small air cylinder and the push plate, so that the wedge-shaped block is released from the limiting effect on the strong ramming hammer, and the strong ramming hammer can fall from a high place to compact the ground, which is more rapid and safer than the unhooking cable in the comparative document.

[0008] Further, the size of the push plate corresponds to the size of the wedge-shaped block, and the shape of the semicircular block corresponds to the shape of the wedge-shaped block.

[0009] Through the above scheme, the push plate can push the wedge-shaped block to move under the action of an external force, and when the semicircular block is inserted into the equipment cabin, the two wedge-shaped blocks can be pushed outward, thereby facilitating the clamping of the strong ramming hammer in the equipment cabin.

[0010] Further, the inner top wall of the equipment cabin is fixedly connected with a cylinder, and the inner wall of the cylinder is slidingly sleeved with a piston.

[0011] Through the above scheme, the piston can be stably moved in the cylinder.

[0012] Further, the bottom end of the piston is fixedly connected with a pressing plate.

[0013] Through the above scheme, the semicircular block can be pressed downward through the pressing plate, thereby facilitating the clamping of the strong ramming hammer in the equipment cabin.

[0014] Further, the top end of the piston is fixedly connected with a second extension spring, and the top end of the second extension spring is fixedly connected with the inner top wall of the cylinder.

[0015] Through the above scheme, when the second telescopic spring is compressed and deformed, the elastic force can be generated, and the piston can be reset by the elastic force generated by the deformation of the second telescopic spring.

[0016] Further, the bottom of the dynamic compactor hammer is embedded with a dynamic pressure sensor.

[0017] Through the above scheme, the dynamic pressure sensor can be arranged to monitor the ramming intensity and the rebound effect of the foundation in real time, and accurate data support is provided.

[0018] Further, the top of the equipment cabin is welded with two supports, and the top end of each support is installed with a load-bearing cable.

[0019] Through the above scheme, the support and the load-bearing cable can be arranged to facilitate the connection of the equipment cabin and the dynamic compactor.

[0020] Further, the upper surface of the equipment cabin is fixedly connected with a counterweight.

[0021] Through the above scheme, the counterweight can be arranged to ensure that the equipment cabin has a certain weight, so that when the equipment cabin is sleeved on the dynamic compactor hammer, the dynamic compactor hammer can be clamped in the equipment cabin by the self-gravity through the clamping mechanism.

[0022] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0023] The foundation dynamic compaction reinforcement equipment is provided with a limiting sleeve, which can clamp the wedge-shaped block between the semi-circular block and the limiting sleeve, thereby effectively avoiding the up-down shaking of the buffer base during the lifting of the dynamic compactor hammer with the equipment cabin, ensuring that the dynamic compactor hammer is more stably fixed in the equipment cabin. In addition, the device is also equipped with a small air cylinder and a push plate, which can quickly and stably push the wedge-shaped block into the sliding groove, thereby releasing the limiting of the dynamic compactor hammer, so that the dynamic compactor hammer can fall from a high place to compact the ground. Compared with the way of using an unhooking cable to release the limiting in the comparative document, the device not only operates more quickly, but also is safer and more reliable.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the ground ramming reinforcement equipment in the embodiment comprises an equipment cabin 1, a rammer 2 and a clamping mechanism 3, the equipment cabin 1 and the rammer 2 are clamped through the clamping mechanism 3, the clamping mechanism 3 comprises a buffer base 301 fixedly connected to the upper surface of the rammer 2 and a limiting sleeve 302 fixedly connected to the outer surface of the buffer base 301, and a semicircular block 303 fixedly connected to the top end of the buffer base 301, the buffer base 301 can relieve the impact force generated when the rammer 2 falls on the ground, the buffer base 301 is internally provided with a partition plate 304, the space in the buffer base 301 is divided into two parts through the partition plate 304, small air cylinders 305 are fixedly connected to the two sides of the partition plate 304, and the output ends of the two small air cylinders 305 are fixedly connected with push plates 306, so that the push plates 306 can move in the horizontal direction when the small air cylinders 305 are started.

[0032] It should be noted that the small air cylinders 305 are connected with an external controller through wireless signals, and the small air cylinders 305 are made of high-strength impact-resistant materials, such as alloy steel or high-performance composite materials, and have good toughness and fatigue resistance, so that the impact force generated when the rammer 2 strikes the ground can be avoided to damage the small air cylinders 305.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4The inner wall of the equipment cabin 1 is fixedly connected with two sliding grooves 307, the inner wall of each sliding groove 307 is slidably connected with a wedge-shaped block 309, the side away from each other of the two wedge-shaped blocks 309 is fixedly connected with a first telescopic spring 308, and the ends away from each other of the two first telescopic springs 308 are fixedly connected with the inner walls of the two sliding grooves 307. When the wedge-shaped block 309 is pushed into the sliding groove 307, the first telescopic spring 308 can be compressed and deformed, and an elastic force is generated. The size of the push plate 306 corresponds to the size of the wedge-shaped block 309, and the shape of the semicircular block 303 corresponds to the shape of the wedge-shaped block 309. Under the action of an external force, the push plate 306 can push the wedge-shaped block 309 to move. At the same time, when the semicircular block 303 is inserted into the equipment cabin 1, the two wedge-shaped blocks 309 can be pushed outward, thereby facilitating the clamping of the rammer 2 in the interior of the equipment cabin 1.

[0034] It should be noted that as shown in Figure 3 , the wedge-shaped block 309 can be clamped between the semicircular block 303 and the limiting sleeve 302 by the limiting sleeve 302. When the rammer 2 moves with the equipment cabin 1, the buffer base 301 will no longer shake, which means that the rammer 2 can be more stably clamped in the interior of the equipment cabin 1. When the limiting effect of the rammer 2 needs to be contacted, and the rammer 2 falls to ram the ground, the two small-sized cylinders 305 can be driven at the same time, so that the two push plates 306 move away from each other. Thus, the two wedge-shaped blocks 309 can be pushed into the corresponding sliding grooves 307. When the wedge-shaped block 309 moves out of the limiting sleeve 302 and the semicircular block 303, the limiting effect on the rammer 2 is released, so that the rammer 2 can freely fall. Compared with the comparative document which uses a hooking cable to pull to release the limiting, the way of using the push plate 306 to push the wedge-shaped block 309 to release the limiting in this device is more stable and convenient, and there is no need to worry about the breaking of the hooking cable.

[0035] Please refer to Figure 2 , Figure 3 and Figure 4 , the inner top wall of the equipment cabin 1 is fixedly connected with a cylinder 310, the inner wall of the cylinder 310 slidably sleeves a piston 311, so that the piston 311 can stably move in the cylinder 310. The bottom end of the piston 311 is fixedly connected with a pressing plate 312. By providing the pressing plate 312, the semicircular block 303 can be pressed downward, thereby facilitating the clamping of the rammer 2 in the equipment cabin 1. The top end of the piston 311 is fixedly connected with a second telescopic spring 313, and the top end of the second telescopic spring 313 is fixedly connected with the inner top wall of the cylinder 310. When the second telescopic spring 313 is compressed and deformed, an elastic force is generated, and the piston 311 can be reset by the elastic force generated by the deformation of the second telescopic spring 313.

[0036] Please refer to Figure 1、 Figure 2 And Figure 3 The bottom of the rammer 2 is inlaid with a dynamic pressure sensor 4, through which the ramming intensity and the rebound effect of the foundation can be monitored in real time, accurate data support is provided, the top of the equipment cabin 1 is welded with two supports 5, the top end of each support 5 is installed with a bearing cable 6, through the setting of the support 5 and the bearing cable 6, the equipment cabin 1 can be conveniently connected with the rammer, the upper surface of the equipment cabin 1 is fixedly connected with a counterweight 7, through the setting of the counterweight 7, the equipment cabin 1 can be guaranteed to have a certain weight, so that when the equipment cabin 1 is sleeved on the rammer 2, the rammer 2 can be clamped in the equipment cabin 1 by means of the self-gravity through the clamping mechanism 3.

[0037] In the embodiment, the wedge-shaped block 309 can be clamped between the semicircular block 303 and the limiting sleeve 302 through the setting of the limiting sleeve 302, so that in the process of the rammer 2 following the equipment cabin 1 rising, the up-and-down shaking of the buffer base 301 can be avoided, the rammer 2 can be more stably clamped in the equipment cabin 1, through the setting of the small air cylinder 305 and the push plate 306, the wedge-shaped block 309 can be quickly and stably pushed into the sliding groove 307, so that the wedge-shaped block 309 releases the limiting effect on the rammer 2, the rammer 2 can be made to fall from a high place to compact the ground, compared with the unhooking cable in the comparative document, the device is more quickly and safely released.

[0038] The working principle of the above embodiment is that the device is connected with the dynamic compactor through the support 5 and the bearing cable 6, then the equipment cabin 1 is moved downward, the through hole at the bottom of the equipment cabin 1 is aligned with the semicircular block 303 at the top of the dynamic compactor 2, and the equipment cabin 1 is quickly clamped on the top of the dynamic compactor 2 by the gravity of the counterweight 7, in the clamping process, the semicircular block 303 is in contact with the two wedge blocks 309, and the two wedge blocks 309 are pushed into the corresponding sliding grooves 307 by the upward movement of the semicircular block 303, at the same time, the corresponding first extension springs 308 are compressed, when the semicircular block 303 moves upward and passes the wedge blocks 309, the wedge blocks 309 are no longer pushed by external force, but are bounced between the semicircular block 303 and the limiting sleeve 302 by the elastic force generated by the compression of the first extension springs 308, so that the clamping of the equipment cabin 1 and the dynamic compactor 2 is completed, then the dynamic compactor moves the equipment cabin 1 and the dynamic compactor 2 to a suitable height through the support 5 and the bearing cable 6, in the moving process, since the wedge blocks 309 are clamped between the semicircular block 303 and the limiting sleeve 302, the buffer base 301 will not shake up and down, and the dynamic compactor 2 cannot shake, when it is needed to release the clamping effect on the dynamic compactor 2, the two small air cylinders 305 are started to make the two push plates 306 move away from each other, so that the two wedge blocks 309 are respectively pushed into the corresponding sliding grooves 307, when the wedge blocks 309 are no longer in contact with the semicircular block 303, the clamping effect on the dynamic compactor 2 is released, so that the dynamic compactor 2 can freely fall and ram on the ground.
