Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile foundation construction equipment technology, and in particular to a duct concrete vibration device. Background Technology
[0002] Currently, during the concrete pouring process for pile foundations, a guide pipe needs to be lowered before concrete pouring. The concrete relies on its own weight to fall freely along the extension direction of the guide pipe and compact itself. However, according to the "Technical Specification for Building Pile Foundations JGJ94-2008", the concrete falling height should not exceed 2 meters, resulting in insufficient gravitational potential energy of the concrete itself. There is a vibration blind zone in the pile head area, which can easily lead to loose concrete and insufficient strength, affecting the pile foundation test results.
[0003] Therefore, it is necessary to use a vibration device to improve the compactness of the concrete at the pile head. However, the existing vibration devices are not versatile enough and cannot be applied to different sizes of guide pipe structures at the same time. Furthermore, the installation process is cumbersome and they are not easy to disassemble. Utility Model Content
[0004] The purpose of this utility model is to provide a duct concrete vibration device that is versatile and easy to install and disassemble.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] The duct concrete vibrating device includes:
[0007] Vibration mechanism;
[0008] The vibration clamp is ring-shaped, with its outer periphery fixedly connected to the output end of the vibration mechanism, and a locking groove provided on its inner periphery. The vibration mechanism is configured to drive the vibration clamp to vibrate.
[0009] A limiting strip extends circumferentially along the conduit structure and is fixedly installed on the outer wall of the conduit structure. When the vibration clamp is sleeved on the outer periphery of the conduit structure, the limiting strip extends into the locking groove and abuts against the inner wall of the locking groove.
[0010] Preferably, the vibration clamp is composed of a fixed segment and two movable segments. One end of the movable segment is a connecting end and the other end is a locking end. The connecting ends of the two movable segments are rotatably connected to the two ends of the fixed segment in a one-to-one correspondence. The two locking ends can abut against each other and lock.
[0011] Preferably, the vibration clamp also includes:
[0012] The locking rod has a connecting block at the locking end of each of the two movable segments. Each of the two connecting blocks has a transition groove. When the two connecting blocks abut against each other, the two transition grooves are connected to each other. One end of the locking rod is rotatably connected to the inner wall of any one of the transition grooves, and the other end can pass through and extend into the other transition groove.
[0013] A locking element, screwed onto the locking rod, is capable of pressing and locking one of the connecting blocks against the other connecting block.
[0014] Preferably, the locking element is provided with a handle.
[0015] Preferably, the handle is provided with an anti-slip structure.
[0016] Preferably, multiple vibration clamps are provided at intervals along the vertical direction.
[0017] Preferably, the output end of the vibration mechanism is detachably provided with a long strip-shaped connecting frame, the connecting frame being long and narrow, and the vibration clamp being fixedly connected to the side of the connecting frame away from the vibration mechanism.
[0018] Preferably, the connecting frame corresponds one-to-one with the vibration clamp.
[0019] The beneficial effects of this utility model are:
[0020] The vibration clamp and the limiting strip work together. When the vibration clamp is fitted on the outer periphery of the guide tube structure, the limiting strip extends into the locking groove and abuts against the inner wall of the locking groove. This prevents relative sliding between the guide tube and the vibration clamp during the vibration process driven by the vibration mechanism, which would affect the compactness of the concrete and the pile formation effect. The device has a simple structure, low manufacturing cost, and is easy to use on-site materials. Attached Figure Description

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] like Figures 1-2 As shown, this utility model provides a vibrating device for duct concrete, used for vibrating duct concrete. The vibrating device includes a vibrating mechanism 1, a vibrating clamp 2, and a limiting strip. The vibrating clamp 2 is annular, with its outer periphery fixedly connected to the output end of the vibrating mechanism 1, and a locking groove formed on its inner periphery. The vibrating mechanism 1 is configured to drive the vibrating clamp 2 to vibrate. The limiting strip extends circumferentially along the duct structure and is fixedly mounted on the outer wall of the duct structure. When the vibrating clamp 2 is fitted onto the outer periphery of the duct structure, the limiting strip extends into the locking groove and abuts against the inner wall of the locking groove.
[0031] The vibration clamp 2 and the limiting strip work together. When the vibration clamp 2 is fitted on the outer periphery of the guide tube structure, the limiting strip extends into the locking groove and abuts against the inner wall of the locking groove. This prevents relative sliding between the guide tube and the vibration clamp 2 during the vibration process driven by the vibration mechanism 1, which would affect the compactness of the concrete and the pile formation effect. In addition, the structure is simple, the manufacturing cost is low, and it is convenient to use local materials on the construction site.
[0032] For example, in this embodiment, the vibration mechanism 1 is an electromagnetic vibrator commonly used in the art, and its working principle and specific structure will not be described in detail here.
[0033] Understandably, the vibration clamp 2 is available in various models with different circumferences to fit different types of conduit structures.
[0034] Specifically, the vibration clamp 2 is composed of a fixed segment 21 and two movable segments 22. One end of the movable segment 22 is a connecting end 221, and the other end is a locking end 222. The connecting ends 221 of the two movable segments 22 are rotatably connected to the two ends of the fixed segment 21 in a one-to-one correspondence. The two locking ends 222 can abut against each other and lock. With the above arrangement, the two movable segments 22 and the fixed segment 21 cooperate with each other, making it easy to put on or take off the vibration clamp 2 from the outer periphery of the conduit. Furthermore, the two locking ends 222 can abut against each other and lock, preventing the vibration clamp 2 from separating from the conduit during vibration.
[0035] More specifically, the vibration clamp 2 also includes a locking rod 23 and a locking element 24. Each of the locking ends 222 of the two movable segments 22 is provided with a connecting block 223. Each connecting block 223 has a transition groove. When the two connecting blocks 223 abut against each other, the two transition grooves are interconnected. One end of the locking rod 23 is rotatably connected to the inner wall of either transition groove, and the other end can pass through and extend into the other transition groove. The locking element 24 is screwed onto the locking rod 23, and the locking element 24 can press and lock one connecting block 223 against the other connecting block 223. With the above arrangement, the locking rod 23 and the locking element 24 cooperate to achieve mutual locking of the two locking ends 222.
[0036] For example, in this embodiment, the locking member 24 is provided with a handle. The handle makes it easier for the operator to rotate the locking member 24.
[0037] For example, in this embodiment, the handle is provided with an anti-slip structure. The anti-slip structure can be an anti-slip pad, such as a rubber pad; or, the anti-slip structure can be an anti-slip protrusion, which can be a dotted protrusion or a textured protrusion of any shape, as long as it can increase the contact friction between its location and the operator's hand. The specific form is in accordance with the prior art and is not specifically limited in this embodiment.
[0038] Specifically, multiple vibration clamps 2 are spaced apart along the vertical direction. This arrangement further improves the stability of the catheter and makes the force on the catheter more even.
[0039] Specifically, the output end of the vibration mechanism 1 is detachably provided with a long strip-shaped connecting frame 11. The connecting frame 11 is long and narrow, and the vibration clamp 2 is fixedly connected to the side of the connecting frame 11 away from the vibration mechanism 1. The connection frame 11 improves the connection strength between the vibration clamp 2 and the output end of the vibration mechanism 1, thereby improving the stability during vibration.
[0040] For example, in this embodiment, the connecting frame 11 is specifically a strip angle steel commonly used in the art, so as to facilitate the use of local materials on the construction site.
[0041] More specifically, the connecting frame 11 is detachably connected to the output end of the vibration mechanism 1 by means of bolts and is welded to the vibration clamp 2 to ensure stability during the vibration process.
[0042] More specifically, the connecting frame 11 corresponds one-to-one with the vibration clamp 2, which can further ensure stability during the vibration process.
[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
