Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a dust prevention device for dynamic compaction hammer. Background Technology

[0002] Currently, most dynamic compaction machines on the market can only meet the requirements of dynamic compaction construction and cannot complete the construction using the full-rotation combined with the grab bucket method. Different types of machinery are required for dynamic compaction and the full-rotation combined with the grab bucket method, resulting in high construction costs. Furthermore, when there are no dynamic compaction tasks, the machines are idle and cannot be used for other construction projects, leading to low utilization rates.

[0003] The existing technology (CN215669435U) discloses a dynamic compaction machine including a frame, a first attachment for connecting to the tamping hammer, a second attachment for connecting to the grab bucket, a third attachment for connecting to a slewing device, and a first winch and a second winch mounted on the frame. The first flexible cable of the first winch and the second flexible cable of the second winch respectively pass around the boom of the frame. The first attachment and the second attachment are selectively connected to the first flexible cable. The first winch is used to drive the first attachment and the second attachment to rise and enable the first attachment and the second attachment to fall freely. The third attachment can be connected to the second flexible cable. The second winch is used to drive the third attachment to move up and down. This technology solves the problem that the existing dynamic compaction machines can only meet the requirements of dynamic compaction construction.

[0004] However, in the above-mentioned scheme, when the hammer falls to compact the ground, it will generate a huge impact force. This impact force will cause dust on the ground to be splashed and float in the air. If workers inhale this dust, it can easily cause injury. Utility Model Content

[0005] The purpose of this utility model is to provide a dust prevention device for dynamic compaction hammers, which aims to solve the problem that when the dynamic compaction hammer falls and contacts the ground during compaction, a huge impact force is generated. This impact force causes dust on the ground to be splashed and float in the air, and this floating dust can easily cause damage to workers' lungs when inhaled.

[0006] To achieve the above objectives, this utility model provides a dust prevention device for a dynamic compaction hammer, including a base and a dust prevention assembly. The dust prevention assembly includes a support member, a hammer, a mounting plate, a support cover, a vacuum cleaner, a collection frame, and a telescopic member. The support member is disposed on one side of the base, the hammer is disposed on one side of the support member, the mounting plate is fixedly connected to the hammer and located on one side of the hammer, the support cover is fixedly connected to the mounting plate and located on one side of the mounting plate, the vacuum cleaner is fixedly connected to the mounting plate and located on one side of the mounting plate, the collection frame is slidably connected to the support cover and located on one side of the support cover, and the telescopic member is disposed on one side of the support cover.

[0007] The supporting component includes a supporting arm, a mounting rod, a winch, and a mounting part. The supporting arm is fixedly connected to the base and located on one side of the base. The mounting rod is fixedly connected to the supporting arm and located on one side of the supporting arm. The winch is fixedly connected to the mounting rod and located on one side of the mounting rod. The mounting part is located on one side of the winch.

[0008] The mounting part includes a lifting rope and a hook. The lifting rope is fixedly connected to the output end of the winch and is located on one side of the winch. The hook is fixedly connected to the lifting rope and is located on one side of the lifting rope.

[0009] The telescopic component includes a spring and a telescopic member. One end of the spring is fixedly connected to the support cover and is located on one side of the support cover. The telescopic member is fixedly connected to the other end of the spring and is located on one side of the spring.

[0010] The dustproof component also includes a movable wheel, which is rotatably connected to the base and located on one side of the base.

[0011] This utility model discloses a dust prevention device for a dynamic compaction hammer. A support member is installed on the base to carry the hammer to a higher position. An mounting plate is fixed to the side of the hammer, connecting to a support cover. The support cover contains a dust collector. During operation, the support member lowers the hammer. Without restraint, the hammer falls rapidly to the ground under its own weight, compacting the soil. Upon impact, the hammer splashes up surrounding dust. A telescopic component extends and retracts upon contact with the ground to prevent damage from the impact. Simultaneously, the dust splashed up is absorbed and neutralized by the dust collector on the support cover, which is activated by the telescopic component. This solution solves the problem in existing dynamic compaction machines where the hammer's impact with the ground generates a huge force, causing dust to splash and float in the air. This airborne dust can be inhaled by workers and cause lung injuries. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a dust prevention device for a dynamic compaction hammer, including a base 101 and a dust prevention component 102. The dust prevention component 102 includes a support member 103, a hammer 104, a mounting plate 105, a support cover 106, a vacuum cleaner 107, a collection frame 108, a telescopic component 109, and a moving wheel 118. The support member 103 includes a support arm 110, a mounting rod 111, a winch 112, and a mounting part 113. The mounting part 113 includes a hook 114 and a lifting rope 115. The telescopic component 109 includes a spring 116 and a telescopic element 117. The aforementioned solution solves the problem that in existing dynamic compaction machines, when the hammer falls and contacts the ground, a huge impact force is generated. This impact force causes dust on the ground to be splashed and float in the air, and this floating dust can be inhaled by workers and cause lung injuries.

[0021] In this specific embodiment, the support member 103 is disposed on one side of the base 101, the counterweight 104 is disposed on one side of the support member 103, the mounting plate 105 is fixedly connected to the counterweight 104 and located on one side of the counterweight 104, the support cover 106 is fixedly connected to the mounting plate 105 and located on one side of the mounting plate 105, the vacuum cleaner 107 is fixedly connected to the mounting plate 105 and located on one side of the mounting plate 105, the collection frame 108 is slidably connected to the support cover 106 and located on one side of the support cover 106, and the telescopic member 109 is disposed on one side of the support cover 106. The support member 103 is mounted on the base 101 to carry the counterweight 104 to a higher position. The mounting plate 105 is fixed to the side of the counterweight 104 and is used to connect the support cover 106. The support cover 106 contains a vacuum cleaner 107. During operation, the support member 103 lowers the hammer 104. Without restraint, the hammer 104 falls rapidly to the ground under its own weight to compact the soil. When the hammer 104 lands, it splashes up surrounding dust. When the hammer 104 contacts the ground, the telescopic member 109 extends and retracts to avoid damage caused by the impact. At the same time, the splashed dust is absorbed and cleaned by the vacuum cleaner 107 covering the support cover 106 with the telescopic member 109. Through the above solution, the problem of the huge impact force generated when the hammer of the existing dynamic compaction machine falls and contacts the ground is solved. This impact force causes the dust on the ground to splash and float in the air, and the dust floating in the air can be inhaled by workers and cause harm.

[0022] The support arm 110 is fixedly connected to the base 101 and located on one side of the base 101. The mounting rod 111 is fixedly connected to the support arm 110 and located on one side of the support arm 110. The winch 112 is fixedly connected to the mounting rod 111 and located on one side of the mounting rod 111. The mounting part 113 is disposed on one side of the winch 112. The support arm 110 is installed on the surface of the base 101 and is used to adjust the support height. Then, the winch 112 is fixed to the high point of the support arm 110 through the mounting rod 111. The output belt end of the winch 112 drives the mounting part 113 to fall down. The counterweight 104 is fixed to the mounting part 113 to compact the ground.

[0023] Secondly, the hoisting rope 115 is fixedly connected to the output end of the winch 112 and is located on one side of the winch 112. The hook 114 is fixedly connected to the hoisting rope 115 and is located on one side of the hoisting rope 115. One end of the hoisting rope 115 is connected to the winch 112, and the other end is connected to the hook 114. The hook 114 is used to hook the counterweight 104. The rotation of the winch 112 winds and releases the hoisting rope 115, thereby adjusting the counterweight 104 suspended by the other end through the hook 114.

[0024] Meanwhile, one end of the spring 116 is fixedly connected to the support cover 106 and located on one side of the support cover 106. The telescopic member 117 is fixedly connected to the other end of the spring 116 and located on one side of the spring 116. During buffering, the telescopic member 117 will cause the spring 116 to undergo elastic deformation after being impacted by the ground. The elastic deformation of the spring 116 will cause the telescopic member 117 to slide into the support cover 106, always maintaining contact with the ground without being damaged, thus preventing dust from falling and splashing. This effectively limits the dust splashing after hitting the ground.

[0025] In addition, the movable wheel 118 is rotatably connected to the base 101 and is located on one side of the base 101. During the process of compacting the ground, the movable wheel 118 drives the whole to repeatedly change positions, ensuring the efficiency and quality of the work.

[0026] In using this utility model, the mounting plate 105 is fixed to the side of the hammer 104. The mounting plate 105 is used to connect the support cover 106. The support cover 106 contains the vacuum cleaner 107. When working, the support member 103 lowers the hammer 104. Without restraint, the hammer 104 falls rapidly downwards under its own weight, compacting the ground. When the hammer 104 lands, it splashes up surrounding dust. When the hammer 104 contacts the ground, the telescopic member 109 extends and retracts to avoid damage caused by impact. The mounting plate 105 is fixed to the side of the hammer 104. The mounting plate 105 is used to connect the support cover 106. The support cover 106 contains the vacuum cleaner 107. When working, the support member 103 lowers the hammer 104. Without restraint, the hammer 104 falls rapidly under its own weight. The hammer 104 falls rapidly downwards and impacts the ground for compaction. Upon impact, it kicks up surrounding dust. During this cushioning process, the telescopic component 117, subjected to the impact force, causes the spring 116 to deform elastically. This deformation allows the telescopic component 117 to slide into the support cover 106, maintaining contact with the ground to prevent dust from splashing up. By effectively limiting dust splashing after impact, the vacuum cleaner 107 on the support cover 106 collects the splashed dust into the collection frame 108 for quiet processing. This solution solves the problem in existing dynamic compaction machines where the hammer impacts the ground with tremendous force, causing dust to splash and float in the air. This airborne dust can be inhaled by workers and cause lung injuries.

Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
