Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a small construction device for building engineering. Background Technology

[0002] Small construction equipment in building engineering typically refers to lightweight, small-sized, flexible, stand-alone equipment used for specific auxiliary processes (as opposed to large machinery such as tower cranes and concrete pump trucks), covering the entire process of surveying and setting out, foundation construction, main structure construction, decoration and finishing, material processing, and auxiliary support.

[0003] A handheld gasoline pile driver is a small construction device that uses a gasoline engine as its power source and repeatedly strikes the pile body with an impact hammer to achieve rapid pile driving. When using it, both hands should firmly grip the handle to keep the machine stable and avoid shaking that could cause the pile body to shift. In the early stages of pile driving, low energy is selected for positioning, followed by high energy penetration in the middle and later stages. When the ground is very hard and cylindrical piles are used, the pile driver generates high-frequency vibrations when high-energy pile driving is selected. This vibration may cause the operator's hands to lose control of the pile driver, resulting in the pile driver striking the pile body at an off-center position, or even striking the side of the pile body instead of the end face. This would cause the pile to be driven crooked and require re-driving. If pile driving is carried out slowly on hard ground, although the operator can support the pile driver, it is very time-consuming and affects work efficiency. Summary of the Invention

[0004] The present invention provides a small construction device for building engineering, which aims to solve the problem that when existing handheld pile drivers drive piles on hard ground, the high-energy impact of the pile driver will generate high-frequency vibration, causing the workers to lose their grip on the pile driver, resulting in the displacement of the pile body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small construction device for building engineering, including a handheld pile driver, with a limit mechanism installed on the outside of the handheld pile driver; The limiting mechanism includes a clamping component, which includes a protective block. The protective block is rotatably connected to the outside of the output end of the handheld pile driver. A hydraulic rod is fixedly connected to the outside of the protective block. The output end of the hydraulic rod passes through the protective block, and a clamping block is fixedly connected to the output end of the hydraulic rod.

[0006] In a preferred embodiment, two hydraulic rods are provided, and the clamping blocks are configured in an arc shape.

[0007] In a preferred embodiment, a cutting component is installed on the outer side of the protective block. The cutting component includes a square groove, which is opened at the end of the protective block away from the handle of the handheld pile driver. There are two square grooves. A square hole is opened inside the square groove. A square block is set inside the square groove. A blade block is fixedly connected to the end of the square block near the opening of the square groove. A sliding block is set inside the square hole. A moving block is fixedly connected to the outer side of the sliding block. A fixed block is fixedly connected to the outer side of the protective block. A hydraulic rod is fixedly connected to the outer side of the fixed block.

[0008] In a preferred embodiment, the sliding block and the square block are fixedly connected, and the sliding block and the protective block are slidably connected.

[0009] In a preferred embodiment, the square block and the protective block are slidably connected, and the output end of the hydraulic rod two is fixedly connected to the moving block.

[0010] In a preferred embodiment, a rotating component is installed between the protective block and the handheld pile driver. The rotating component includes a gear, which is fixedly connected to the end of the protective block away from the square groove opening. A slider is fixedly connected to the end of the gear away from the protective block. A sliding groove is provided at the end of the handheld pile driver near the gear, and several sliders are provided.

[0011] In a preferred embodiment, the slider is disposed inside the groove, and the slider and the handheld pile driver are slidably connected.

[0012] In a preferred embodiment, a motor is fixedly connected to the outside of the handheld pile driver, a rotating shaft is fixedly connected to the output end of the motor, and a second gear is fixedly connected to the end of the rotating shaft away from the motor, with the second gear meshing with the first gear.

[0013] The beneficial effects of this utility model are as follows: This utility model uses a clamping component of a limiting mechanism to directly clamp the pile body with a clamping block when the operator uses a handheld pile driver. However, the clamping is not tight. While limiting the position, it also facilitates the sliding of the pile body, making it easier for the operator to drive the pile quickly and preventing high-frequency vibration from causing the pile to shift position.

[0014] This invention, through the design of a cutting component and a rotating component, allows workers to directly apply high-frequency vibration from the start when using a handheld pile driver, especially when driving short and thick piles. This eliminates the need for initial low-frequency vibration and improves work efficiency. The rotating component is designed to locate the soft areas on both sides of the pile body where it needs to be driven, facilitating the operation of the cutting component.

[0025] A cutting component 22 is installed on the outside of the protective block 211. The cutting component 22 includes a square groove 221. The square groove 221 is opened at the end of the protective block 211 away from the handle of the handheld pile driver 1. There are two square grooves 221. A square hole 222 is opened inside the square groove 221. A square block 223 is set inside the square groove 221. A blade block 224 is fixedly connected to the end of the square block 223 near the opening of the square groove 221. A sliding block 225 is set inside the square hole 222. A moving block 226 is fixedly connected to the outside of the sliding block 225. A fixing block 227 is fixedly connected to the outside of the protective block 211. A hydraulic rod 228 is fixedly connected to the outside of the fixing block 227.

[0026] Sliding block 225 and square block 223 are fixedly connected, and sliding block 225 and protective block 211 are slidably connected.

[0027] Square block 223 and protective block 211 are slidably connected, and the output end of hydraulic rod 228 and moving block 226 are fixedly connected.

[0028] It should be noted that the two directional slots are respectively set at the front and rear ends of the bottom side of the protective block 211, the front square hole 222 is opened in the front side inside the front square slot 221, and the rear square hole 222 is opened in the rear side inside the rear square slot 221.

[0029] A rotating component 23 is installed between the protective block 211 and the handheld pile driver device 1. The rotating component 23 includes a gear 231, which is fixedly connected to the end of the protective block 211 away from the opening of the square groove 221. A slider 232 is fixedly connected to the end of the gear 231 away from the protective block 211. A sliding groove 233 is provided at the end of the handheld pile driver device 1 near the gear 231. Several sliders 232 are provided.

[0030] The slider 232 is located inside the slide groove 233, and the slider 232 is slidably connected to the handheld pile driver device 1.

[0031] A motor 234 is fixedly connected to the outside of the handheld pile driver device 1. A rotating shaft 235 is fixedly connected to the output end of the motor 234. A gear 236 is fixedly connected to the end of the rotating shaft 235 away from the motor 234. Gear 236 and gear 1 are meshed together.

[0032] It should be noted that gear 231 is fixed to the upper end of protective block 211, and the front view cross section of slider 232 and slide groove 233 is set as T-shaped to facilitate the stability of related structures of protective block 211.

[0033] In this embodiment, the specific implementation scenario is as follows: When the worker prepares to use the handheld pile driver 1 for pile driving, he first lifts the device and then puts the pile body inside the protective block 211. The hydraulic rods 212 on both sides of the protective block 211 are activated, allowing the hydraulic rods 212 to clamp the pile body with the arc-shaped clamping blocks 213. The pile body is cylindrical, which is conducive to the clamping of the clamping blocks 213. The clamping force is maintained to ensure a tight grip without affecting the force of the device's impact and sliding. Then, the handheld pile driver 1 is held perpendicular to the ground, aimed at the pile driving position, and the device is started to drive the pile directly. First, the pile is driven slowly at a low frequency, and then it is driven quickly at a high frequency until the pile body is completely in the ground.

[0034] When workers prepare to drive shorter wooden piles, they clamp the pile body directly in the clamping component 21, then allow the equipment to carry the pile body vertically to the ground. At this time, hydraulic rod 228 is activated, which moves moving block 226, which in turn moves sliding block 225, which in turn moves square block 223. Square block 223, along with blade block 224, moves to cut the ground, embedding square block 223 into the ground. Maintaining this position, the handheld pile driver 1 is activated to use high-frequency vibration to drive the pile body, allowing it to penetrate the ground more quickly. When blade block 224... When cutting the ground, if the ground is too hard for the blade to cut, or if there is an iron block hidden inside the ground that the blade block 224 cannot cut, the motor 234 can be started. The motor 234 drives the rotating shaft 235 to rotate, the rotating shaft 235 drives the second gear 236 to rotate, the second gear 236 drives the first gear 231 to rotate, and the first gear 231 drives the protective block 211 and related structures of the blade block 224 to rotate, so that the blade block 224 rotates to change the cutting position of the ground until a position is found where the square block 223 can enter the ground. Then the motor 234 is stopped. The equipment is started in this way so that the impact hammer head can strike the pile body at high frequency.

[0035] Working principle: First, the staff clamps the cylindrical pile body with the clamping component 21, then holds the handheld pile driver equipment 1 vertically to the ground, and then slowly starts the equipment to hit the pile body, and then uses the impact hammer head to hit the pile body with high frequency vibration.

[0036] 2. When the staff chooses to strike a shorter cylindrical pile, they still first clamp the pile, then make the equipment perpendicular to the ground, then let the blade block 224 of the cutting component 22 cut the ground, let the square block 223 slide into the ground, and then directly use the impact hammer head to strike at high frequency.

[0037] Third, when the ground cut by the blade block 224 is relatively hard, the rotating component 23 is activated to rotate the blade block 224 and change to a softer ground near the pile. Then, the square block 223 is slid into the ground and the impact hammer head is still directly struck at high frequency.

[0038] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
