Description

Technical Field

[0001] The utility model relates to the field of engineering piling, in particular to a construction engineering piling device. Background Art

[0002] In the field of construction engineering technology, piling is a process of driving a pile into the ground to facilitate subsequent construction operations. A piling device is required during piling. Currently, there are three methods for piling: hydraulic lift hammer piling, vibratory hammer piling, and spiral bored pile driving. Both hydraulic lift hammer piling and vibratory hammer piling require the use of prefabricated piles. Currently, when hydraulic lift hammer piling is used to drive piles, the hydraulic equipment drives the pile driver to intermittently strike the top of the pile to drive it into the ground. However, during the piling process, the pile driver is in direct contact with the top of the pile, and intermittent hammering not only easily damages the top surface of the pile, but also generates a lot of noise, causing noise pollution.

[0003] Therefore, it is necessary to invent a kind of construction engineering piling device. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a construction engineering piling device, comprising a soundproof cover and a pile column, the upper end of the pile column being inserted into the inside of the soundproof cover, the upper end of the soundproof cover being connected to a guide tube, a telescopic rod being inserted into the inside of the guide tube, a hydraulic hammer being installed at the lower end of the telescopic rod, support plates being fixedly installed on both sides of the outside of the guide tube, limiting components being symmetrically installed on both sides of the support plates, an anti-collision plate being movably provided in the inner cavity of the soundproof cover, and a sound insulation felt being installed at the upper end of the anti-collision plate.

[0006] Based on the above characteristics: before the construction of a building project needs to impact the pile into the ground, the entire piling device can be lifted by a crane first, and then the lower end of the pile is aligned with the position that needs to be impacted into the ground, and the upper end of the pile needs to be located inside the sound insulation cover. During this process, the upper end of the pile can lift the anti-collision plate upwards, and when the pile needs to be impacted into the ground, the hydraulic cylinder is started to drive the hydraulic hammer to intermittently rise and fall inside the guide tube through the telescopic rod. When the hydraulic hammer descends, the hydraulic hammer will hit the anti-collision plate, and the anti-collision plate is located above the pile. At this time, the pile will be hammered into the ground. Since the surface of the anti-collision plate is also provided with sound insulation felt, the anti-collision plate and the sound insulation felt cooperate to not only avoid the hydraulic hammer from directly hitting the pile, but also will not affect the effect of the pile impacting the ground, so that the upper end surface of the pile will not be damaged when it is impacted downward by the hydraulic hammer, and the noise generated by the impact can also be reduced.

[0007] Preferably, an anti-slip convex plate is fixedly mounted on the inner wall of the lower end of the soundproof cover.

[0008] Based on the above features: the sound insulation cover can provide sound insulation protection on the outside of the upper end of the pile, and the anti-fall-off convex plate prevents the anti-collision plate from falling down by itself.

[0009] Preferably, the limiting assembly includes a movable groove and sliding grooves symmetrically opened on both sides of the movable groove, a cylinder is installed at one end of the inner cavity of the movable groove, and a limiting plate is installed at the telescopic end of the cylinder.

[0010] Based on the above features: the movable grooves are symmetrically opened on both sides of the support plate. After the cylinder is powered on, the telescopic end can be used to drive the limit plate to move telescopically. At this time, the limit plate can be guided by the movable groove and the sliding groove to maintain translation.

[0011] Preferably, sliders are symmetrically installed on both sides of the upper end of the limiting plate, and a clamping plate is installed on one side of the lower end of the limiting plate.

[0012] Based on the above features: the limit plates are slidably connected to the slide grooves by means of sliders. When the two limit plates move towards each other, the clamping plates can be used to limit the upper end of the pile column so that the pile column remains vertical when impacting downward).

[0013] Preferably, a positioning groove is provided on the side of the anti-collision plate, a positioning convex plate is inserted into the positioning groove, a buffer spring is installed on one side of the positioning convex plate, and a moving part is installed on the lower end of the positioning convex plate close to the buffer spring.

[0014] Based on the above features: when the upper end of the pile is not inserted into the sound insulation cover, the anti-collision plate will fall downward by itself. Due to the limitation of the anti-fall-off convex plate, the anti-collision plate will not fall off the sound insulation cover. When the anti-collision plate or the sound insulation felt is damaged and needs to be replaced, the positioning convex plate can be pulled by the moving part to move the positioning convex plate so that the positioning convex plate retracts into the positioning groove. At this time, the anti-collision plate and the sound insulation felt can fall off from under the sound insulation cover, making it convenient to replace the anti-collision plate or the sound insulation felt.

[0015] Preferably, a movable groove is provided on the lower end surface of the positioning groove, and the movable groove is located on the bottom surface of the anti-collision plate.

[0016] Based on the above features: the moving part is movable through the moving groove, which makes it convenient for personnel to pull the positioning convex plate through the lower end of the sound insulation cover and the anti-collision plate to move.

[0017] Preferably, the movable member includes a fixed plate and a through slot at the bottom of the fixed plate, a movable pull plate is inserted into the through slot, a piston plate is installed at the upper end of the movable pull plate, and a compression spring is installed at the upper end of the piston plate.

[0018] Based on the above features: the fixed plate is located inside the movable groove, and the lower end of the fixed plate extends out of the movable groove through the movable pull plate, making it convenient for personnel to pull the extended movable pull plate to drive the positioning protruding plate to move.

[0019] The beneficial effects of the utility model are:

[0020] 1. When the construction project needs to impact the pile column into the ground, the upper end of the pile column will be located inside the sound insulation cover. During this process, the upper end surface of the pile column will contact the bottom surface of the anti-collision plate. At this time, the pile column will push up the anti-collision plate. When the pile column needs to be impacted into the ground, the hydraulic hammer is used to lift and lower it intermittently. When the hydraulic hammer descends, the hydraulic hammer will hit the sound insulation felt and the anti-collision plate. Since the anti-collision plate is located above the pile column, the pile column will be hammered into the ground at this time. The anti-collision plate and the sound insulation felt can not only prevent the hydraulic hammer from directly hitting the pile column, but also will not affect the effect of the pile column being impacted into the ground, so that the upper end surface of the pile column will not be damaged when it is impacted downward by the hydraulic hammer, and the noise generated by the impact can also be reduced.

[0021] 2. When the pile is separated from the sound insulation cover, the anti-collision plate and the sound insulation felt will fall down by themselves. At this time, the buffer spring can extend the positioning convex plate outward through the positioning groove, so that the anti-falling convex plate can limit the positioning convex plate at the lower end of the inner wall of the sound insulation cover to prevent the anti-collision plate and the sound insulation felt from falling off the sound insulation cover. When the anti-collision plate or the sound insulation felt is damaged and needs to be replaced, the positioning convex plate can be pulled by moving the pull plate to move the positioning convex plate so that the positioning convex plate retracts into the positioning groove. At this time, the anti-collision plate and the sound insulation felt can fall off from under the sound insulation cover, which is convenient for replacing the anti-collision plate or the sound insulation felt.

[0022] 3. When the upper end of the pile is inserted into the soundproof cover, the pile will push the anti-collision plate upward. At this time, the movable pull plate will be pushed into the inner side of the fixed plate through the through groove. At the same time, the movable pull plate will be squeezed by the piston plate to deform the compression spring. When the pile is separated from the soundproof cover, the movable pull plate will be rebounded and extended outward by the compression spring, making it convenient for personnel to move the positioning convex plate by pulling the movable pull plate.

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0029] Refer to the attached Figure 1-4 The utility model provides a construction engineering piling device, including a sound insulation cover 1 and a pile column 9. The upper end of the pile column 9 is inserted into the inside of the sound insulation cover 1. The upper end of the sound insulation cover 1 is connected to a guide tube 2. A telescopic rod 3 is inserted into the inside of the guide tube 2. A hydraulic hammer 4 is installed at the lower end of the telescopic rod 3. Support plates 5 are fixedly installed on both sides of the outside of the guide tube 2. Limiting components 6 are symmetrically installed on both sides of the support plate 5. An anti-collision plate 7 is movably provided in the inner cavity of the sound insulation cover 1 (the anti-collision plate 7 is supported by D3O material, which belongs to the category of "expanding foam" material. It can present two mechanical-like states under different gravity impacts, hard and soft, and has good impact resistance), and a sound insulation felt 8 is installed on the upper end of the anti-collision plate 7.

[0030] The upper end of the telescopic rod 3 is connected to the hydraulic cylinder, which is not shown in the figure of this application. The prior art will not be described in detail. When the construction project needs to impact the pile column 9 into the ground, the entire pile driving device can be lifted by a crane first, and then the lower end of the pile column 9 is aligned with the position where it needs to be impacted into the ground, and the upper end of the pile column 9 needs to be located inside the sound insulation cover 1. During this process, the upper end of the pile column 9 can push the anti-collision plate 7 upward. When the pile column 9 needs to be impacted into the ground, the hydraulic cylinder is started to drive the hydraulic hammer through the telescopic rod 3. The hydraulic hammer 4 is intermittently raised and lowered inside the guide tube 2. When the hydraulic hammer 4 descends, it will hit the anti-collision plate 7, which is located above the pile 9. At this time, the pile 9 will be hammered into the ground. Since the anti-collision plate 7 is also provided with a sound insulation felt 8 on the surface, the anti-collision plate 7 cooperates with the sound insulation felt 8 to not only prevent the hydraulic hammer 4 from directly hitting the pile 9, but also do not affect the effect of the pile 9 hitting the ground, so that the upper end surface of the pile 9 will not be damaged when it is hit downward by the hydraulic hammer 4, and the noise generated by the impact can also be reduced.

[0031] Preferably, an anti-slip convex plate 11 is fixedly mounted on the inner wall of the lower end of the soundproof cover 1 .

[0032] The soundproof cover 1 can provide sound insulation protection outside the upper end of the pile column 9, and the anti-fall-off convex plate 11 prevents the anti-collision plate 7 from falling downward by itself.

[0033] Preferably, the limiting assembly 6 includes a movable groove 61 and sliding grooves 62 symmetrically provided on both sides of the movable groove 61 . A cylinder 63 is installed at one end of the inner cavity of the movable groove 61 , and a limiting plate 64 is installed at the telescopic end of the cylinder 63 .

[0034] The movable grooves 61 are symmetrically arranged on both side surfaces of the support plate 5. After the cylinder 63 is powered on and started, the telescopic end can be used to drive the limit plate 64 to telescopically move. At this time, the limit plate 64 can be guided by the movable grooves 61 and the slide grooves 62 to maintain translation.

[0035] Preferably, sliders 641 are symmetrically installed on both sides of the upper end of the limiting plate 64, and a clamping plate 642 is installed on one side of the lower end of the limiting plate 64.

[0036] The limiting plate 64 is slidably connected to the slide groove 62 by the slider 641. When the two limiting plates 64 move toward each other, the clamping plate 642 can be used to limit the upper end of the pile column 9 so that the pile column 9 remains vertical when impacting downward (the piling device will move synchronously with the descent of the pile column 9).

[0037] Preferably, a positioning groove 71 is opened on the side of the anti-collision plate 7, a positioning convex plate 72 is inserted into the positioning groove 71, a buffer spring 73 is installed on one side of the positioning convex plate 72, and a moving part 74 is installed on the lower end of the positioning convex plate 72 close to the buffer spring 73.

[0038] When the upper end of the pile 9 is not inserted into the interior of the sound insulation cover 1, the anti-collision plate 7 will fall downward by itself. At this time, the buffer spring 73 can extend the positioning protrusion 72 outward through the positioning groove 71, so that one side of the positioning protrusion 72 contacts the inner wall of the sound insulation cover 1. When the anti-collision plate 7 falls downward, due to the limitation of the anti-fall-off protrusion 11, the anti-collision plate 7 will not fall off from the sound insulation cover 1. When the anti-collision plate 7 or the sound insulation felt 8 is damaged and needs to be replaced, the positioning protrusion 72 can be pulled out by the moving part 74 to move the positioning protrusion 72 so that the positioning protrusion 72 retracts into the positioning groove 71. At this time, the anti-collision plate 7 and the sound insulation felt 8 can fall off from the bottom of the sound insulation cover 1, which is convenient for replacing the anti-collision plate 7 or the sound insulation felt 8.

[0039] Preferably, a moving groove 711 is formed on the lower end surface of the positioning groove 71 , and the moving groove 711 is located on the bottom surface of the anti-collision plate 7 .

[0040] The movable member 74 is movable through the movable groove 711 , so that a person can easily pull the positioning protruding plate 72 through the lower end of the soundproof cover 1 and the anti-collision plate 7 to move.

[0041] Preferably, the movable member 74 includes a fixed plate 741 and a through slot 742 at the bottom of the fixed plate 741 , a movable pull plate 743 is inserted into the through slot 742 , a piston plate 744 is installed on the upper end of the movable pull plate 743 , and a compression spring 745 is installed on the upper end of the piston plate 744 .

[0042] When the locking cam 730 is in the unlocked position, the locking cam 730 will be in the unlocked position, and the winch 72 will be unlocked when the winch 730 is unlocked.

[0043] The use process of the present invention is as follows: before the pile column 9 needs to be impacted into the ground during construction, the entire pile driving device can be hoisted by a crane first, and then the lower end of the pile column 9 is aligned with the position where it needs to be impacted into the ground, and the upper end of the pile column 9 needs to be located inside the sound insulation cover 1. During this process, the upper end surface of the pile column 9 will contact the bottom surface of the anti-collision plate 7. At this time, the pile column 9 will push the anti-collision plate 7 upward. When the pile column 9 needs to be impacted into the ground, the hydraulic hammer 4 is used to lift and lower it intermittently. When the hydraulic hammer 4 When descending, the hydraulic hammer 4 will hit the sound insulation felt 8 and the anti-collision plate 7. Since the anti-collision plate 7 is located above the pile column 9, the pile column 9 will be hammered into the ground at this time, and the anti-collision plate 7 cooperates with the sound insulation felt 8 to prevent the hydraulic hammer 4 from directly contacting the upper end of the pile column 9. When the sound insulation felt 8 or the anti-collision plate 7 is damaged by the collision, the positioning protrusion 72 can be pulled by moving the pull plate 743 to displace the positioning protrusion 72, so that the positioning protrusion 72 retracts into the positioning groove 71. At this time, the anti-collision plate 7 and the sound insulation felt 8 can fall off from under the sound insulation cover 1.

Anyone skilled in the art may utilize the above-described technical solutions to modify the present invention or create equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
