Description

Technical Field

[0001] This utility model relates to the field of airport runway construction technology, specifically a compaction device for runway construction. Background Art

[0002] During the compaction process in airport construction, various sizes of rammers are used, including smaller manual rammers and high-speed hydraulic rammers mounted on excavators for foundation compaction. These devices are suitable for various types of soil, especially for high fills and soft soils that are difficult to handle using traditional methods. Because airport construction requires extremely high foundation bearing capacity, multiple compaction operations are necessary to reinforce the soil and improve its bearing capacity. When using manually propelled rammers, multiple rammers are arranged in a row and operated simultaneously, with personnel maintaining equal spacing. However, after rain, the soil is slippery and has a high water content, causing mud to splash during compaction. Manual rammer operation can affect surrounding personnel. Furthermore, some rammers have curved steel plates at the bottom for contact with the soil; although these plates are relatively smooth, the initially compacted foundation soil is uneven, and if the soil is slippery, the rammer becomes even more difficult to move and use.

DETAILED DESCRIPTION

[0032] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0033] Please see Figure 1-5In this embodiment of the utility model, a compaction device for runway construction includes a mounting shell 100, a tamping unit 110 fixedly installed inside the mounting shell 100, a drive unit 120 fixedly installed on the top of the tamping unit 110, multiple limiting shells 200 fixedly connected to the outside of the mounting shell 100, multiple connecting arms 210 rotatably connected inside the limiting shells 200, multiple support cylinders 220 rotatably connected at both ends to adjacent connecting arms 210, a second protective pad 230 rotatably connected to the bottom of the limiting shells 200, and a control module 240 installed inside the limiting shells 200, capable of driving the support cylinders 220.

[0034] Specifically, protective pads 230 are rotatably connected to the bottom of the limiting shell 200. The two protective pads 230 can shield the sides of the mounting shell 100 to prevent mud from splashing onto the surrounding workers during the tamping operation. The hydraulic rod 246 can lift the mounting shell 100 through multiple auxiliary wheels 247. The motor 243 can rotate the connecting arm 210 so that the support cylinder 220 contacts the ground. At the same time, the two protective pads 230 rotate and separate from the ground. The support cylinder 220, together with the auxiliary wheels 247, can facilitate the movement of the mounting shell 100 on wet and slippery soil, making the transfer of the equipment between multiple tamping points more labor-saving and convenient to use.

[0035] Example 1

[0036] like Figure 3-4 As shown, in this embodiment, the control module 240 includes multiple shafts 241, which are rotatably connected to adjacent outer walls of the mounting housing 100. A connecting plate 2411 is fixedly connected to the outside of the shafts 241, a second protective pad 230 is fixedly connected to the connecting plate 2411, a first spur gear 2412 is fixedly sleeved on the outside of the shafts 241, and two first bevel gears 2413 are provided and fixedly sleeved on the outside of the shafts 241. The two first bevel gears 2413 are symmetrically distributed. Multiple round rods 242 are provided and rotatably connected to the outer wall of the mounting shell 100. The round rods 242 pass through the adjacent connecting arms 210 and are fixedly connected to them. The second bevel gear 2421 is fixedly sleeved on one end of the round rod 242. The second bevel gear 2421 meshes with the adjacent first bevel gear 2413. The inner wall of the limiting shell 200 is fixedly connected to the motor 243. The second spur gear 2431 is fixedly sleeved on the output end of the motor 243. The second spur gear 2431 meshes with the first spur gear 2412.

[0037] In this embodiment, when the shaft 241 rotates, the connecting arm 210 can be driven to rotate through the transmission of bevel gear 1 2413 and bevel gear 2421, thereby lowering the two support cylinders 220 to contact the ground. The two support cylinders 220 can cooperate with the auxiliary wheel 247 to move the equipment. At the same time, the shaft 241 drives the protective pad 230 to rotate and detach from the ground through the connecting plate 2411, preventing the protective pad 230 from scratching the ground and affecting the movement of the mounting shell 100. When the shaft 241 rotates in the opposite direction, the two support cylinders 220 contact the ground. Separation allows the mounting shell 100 and the tamping unit 110 to contact the ground for tamping operations. Simultaneously, the second protective pad 230 rotates and contacts the ground, shielding both sides of the mounting shell 100 to prevent mud splashing. Starting the motor 243 drives the second spur gear 2431 to rotate, which in turn drives the shaft 241 to rotate via the transmission between the spur gear 2431 and the bevel gear 2421. This provides power for the rotation of the shaft 241, allowing the mounting shell 100 to switch between two modes: travel and deployment for tamping operations.

[0038] like Figure 1-2 As shown, in this embodiment, a movable plate 130 is fixedly connected to the bottom of the mounting shell 100, a plurality of mounting rods 140 are fixedly connected to the top of the mounting shell 100, a protective shell 150 is fixedly connected between the plurality of mounting rods 140, a push rod 160 is rotatably connected to the outer wall of the mounting shell 100, and a protective pad 170 is fixedly connected to the outer wall of the mounting shell 100.

[0039] In practice, the drive unit 120 drives the tamping unit 110, the mounting rod 140 works with the protective shell 150 to protect the drive unit 120, and the push rod 160 is used for the operator to grip and move the equipment. Both the protective pad 170 and the protective pad 230 are made of polyurethane. Polyurethane pads have the characteristics of super wear resistance, high wear resistance, and heat resistance. They are suitable for various working conditions, have a wide range of hardness options, are soft and elastic, and have a certain degree of airtightness. The protective pad 170 can shield the mud behind the mounting shell 100 to prevent mud from splashing onto the operator. The protective pad 230 can protect the two sides of the mounting shell 100 to prevent mud caused by tamping from splashing onto the surrounding workers.

[0040] Example 2

[0041] Based on Embodiment 1, in order to make the limiting of the connecting arm 210 more stable, the mounting shell 100 can move more smoothly.

[0042] like Figure 3-5As shown, in this embodiment, multiple T-shaped plates 244 are fixedly connected to the inner bottom surface of the limiting shell 200, and multiple limiting rods 2441 are fixedly connected to the bottom of the T-shaped plates 244. A fixing plate 245 and a rectangular plate 248 are provided inside the limiting shell 200. The limiting rods 2441 pass through the adjacent fixing plates 245 and rectangular plates 248. An auxiliary wheel 247 is fixedly connected to the bottom of the fixing plate 245. The auxiliary wheel 247 passes through the limiting shell 200 and extends to its outside. Multiple hydraulic rods 246 are fixedly connected to both outer walls of the mounting shell 100. The output end of the hydraulic rod 246 is fixedly connected to the top of the adjacent fixing plate 245. An insert rod 2481 is fixedly connected to the top of the rectangular plate 248. The insert rod 2481 can be movably engaged with the adjacent connecting arm 210. Multiple hydraulic rods 249 are fixedly connected to the inner bottom surface of the limiting shell 200. The output end of the hydraulic rod 249 is fixedly connected to the bottom of the adjacent rectangular plate 248.

[0043] In practice, the T-shaped plate 244, in conjunction with the limiting rod 2441, slides and limits the fixed plate 245 and the rectangular plate 248, thereby vertically limiting the auxiliary wheel 247. Before rotating the connecting arm 210 to make the support cylinder 220 contact the ground, multiple hydraulic rods 246 are activated to move multiple auxiliary wheels 247 down to contact the ground. The auxiliary wheels 247 then lift the mounting shell 100, creating a certain distance and space between the mounting shell 100 and the ground. Then, the connecting arm 210 is rotated and the support cylinder 220... Contact with the ground can distribute the force on the connecting arm 210 and the support cylinder 220, preventing the mounting shell 100 from being lifted up by the rotation of the connecting arm 210 and the support cylinder 220 and subjected to excessive force. After the connecting arm 210 rotates and the support cylinder 220 contacts the ground, the hydraulic rod 249 is activated to drive the rectangular plate 248 to move upward and insert the insertion rod 2481 into the adjacent connecting arm 210, thereby strengthening and limiting the deployment of the connecting arm 210 and the support cylinder 220 and reducing the force on the transmission components such as the bevel gear 2421 and the bevel gear 2413.
