Description

Technical Field

[0001] This utility model relates to a vibratory double-headed insertion device for grouting modified concrete. Background Technology

[0002] Modified concrete, a composite concrete material formed by incorporating cement paste into roller-compacted concrete (RCC), combines the high strength of RCC with the good density of ordinary concrete. It is widely used in large-volume concrete projects such as water conservancy projects and large factory foundations. The core of its construction quality lies in the uniform integration of cement paste and RCC aggregate. A key process for achieving this is creating uniformly distributed pores in the unconsolidated RCC base layer using a perforator, providing channels for the penetration and diffusion of the cement paste.

[0003] The modified concrete insertion equipment currently used in the project has many obvious defects:

[0004] Traditional single-head socketers are inefficient, as they can only complete the construction of one hole at a time, making it difficult to meet the needs of large-area operations.

[0005] Some dual-head devices use a single vibration source to drive two insertion rods, resulting in uneven transmission of vibration energy. This often leads to problems such as one insertion rod being inserted too deeply and the other being inserted too deeply, affecting the consistency of the hole quality.

[0006] Meanwhile, the insertion depth adjustment mechanism of existing equipment is mostly bolt-fixed, and the adjustment process requires repeated disassembly with the help of tools. The operation is cumbersome and the accuracy is difficult to control. It is easy to cause uneven penetration of the grout due to depth deviation, which in turn leads to differences in the internal density of the concrete.

[0007] In addition, most socketers lack effective limiting and protection structures. When not in use, the tip of the plug is in direct contact with the ground, which can easily cause wear and affect the sharpness of subsequent sockets. During construction, vibration energy can be easily transmitted to the operator's hands through the equipment frame. Long-term operation can easily cause fatigue and reduce construction safety and efficiency.

[0008] To address the aforementioned technical challenges, there is an urgent need to develop a high-efficiency, precise, easy-to-operate, and protective vibratory double-headed insertion device for adding grout to deformed concrete. Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide a high-efficiency, precise, easy-to-operate, and protective vibratory double-headed insertion device for grouting modified concrete.

[0010] To solve the above problems, the present invention adopts the following technical solution:

[0011] A vibratory double-headed jack for modified concrete with grouting, comprising,

[0012] An upper frame contains a drive rod rotatably mounted within it via bearings. One end of the drive rod extends to the outside of the upper frame, and a handle is mounted at that end. The drive rod has two drive threads with opposite directions of rotation. A support block is positioned at the center of the upper frame, and a through hole, through which the drive rod passes, is transversely formed on the side of the support block.

[0013] Two sliding blocks are provided, both located within the upper frame and each fitted with a section of the drive thread. A nut that fits the drive thread is provided inside the sliding block. A vibration rod is fixed to the bottom of the sliding block. The lower end of the vibration rod is a pointed tip. A vibration motor is installed on the side of the vibration rod near the top.

[0014] A support rod is fixed to the top of the support block by a fastener, and a second handle is provided on the outer wall of the support rod near the top.

[0015] A limiting device is provided, the distance between the limiting device and the upper frame is adjustable, and the lower end of the vibration rod passes through the limiting device and contacts the ground plane through the limiting device.

[0016] Preferably, a shock-absorbing grip sleeve is fitted onto the second handle.

[0017] Preferably, the limiting device includes a limiting plate, guide rods, and an adjusting device. The limiting plate is arranged parallel to the lower part of the upper frame, and the distance between the limiting plate and the upper frame is adjustable. Multiple guide rods are provided. A guide plate is provided on the outer side of the upper frame. The guide plate is provided with holes for the guide rods to pass through. The guide rods slide along the axial direction of the holes. A strip groove is provided on the surface of the limiting plate. The vibrating rod passes through the strip groove and can slide laterally along the strip groove. A base is fixedly provided at the middle position of the strip groove. The base corresponds to the support block. The adjusting device is installed between the support block and the base.

[0018] Preferably, the upper end of the guide rod is threaded with a limit cap, which limits the downward movement of the guide rod. When the limit cap contacts the guide plate, the vibrating rod moves above the limit plate.

[0019] Preferably, the adjusting device includes a bearing seat, a rotating tube, and a fixed rod. The bearing seat is fixed to the top of the base, the rotating tube is rotatably mounted in the bearing seat via a bearing, and the fixed rod is fixed to the bottom of the support block. The rotating tube and the fixed rod are threaded together. A rotating ring is provided near the top of the rotating tube, and a connecting rod is fixed between the rotating ring and the rotating tube.

[0020] Preferably, an outer retaining edge is provided at the top edge of the limiting plate, and an inner retaining edge is provided at the top of the limiting plate, located at the edge of the strip groove.

[0021] The beneficial effects of this utility model are:

[0022] 1. Improve construction efficiency and hole layout accuracy

[0023] The device employs a dual-head synchronous operation design. With two opposing drive threads on the drive rod, rotating the handle allows for synchronous reverse or same-direction lateral movement of the two vibrating rods, quickly adjusting the hole spacing to adapt to different construction needs. Compared to traditional single-head equipment, construction efficiency is more than doubled. Simultaneously, each vibrating rod is equipped with an independent vibration motor, ensuring uniform vibration energy transmission and effectively avoiding insertion depth deviations caused by a single vibration source. The limiting plate has a large contact area with the ground, combined with a precisely adjustable depth control mechanism, keeping the insertion depth error within 5mm, significantly improving the consistency of hole layout quality and ensuring uniform slurry penetration.

[0024] 2. Convenient depth adjustment and strong stability

[0025] The innovatively designed threaded adjustment device achieves stepless adjustment of the limit plate height by driving the rotating tube and fixed rod to rotate relative to each other via a rotating ring. No additional tools are required, making the adjustment process time-saving and labor-saving. The mating structure of the guide rod and guide plate ensures that the limit plate remains parallel to the upper frame, preventing depth deviations caused by tilting during adjustment. The limit cap effectively prevents the limit plate from overtraveling downwards, further enhancing the safety and reliability of the adjustment operation. Compared to traditional bolt-fixed adjustment mechanisms, this device offers improved depth adjustment efficiency and higher precision.

[0026] 3. Excellent operating comfort and equipment protection.

[0027] The EVA shock-absorbing grip sleeve on the second handle effectively absorbs the vibration force transmitted by the vibratory motor, reducing hand vibration amplitude by more than 40%, significantly reducing the operator's labor intensity and improving comfort during long-term operation. In the idle state, the lowering limit device allows the vibratory rod tip to be higher than the limit plate, ensuring stable placement of the equipment, preventing wear caused by the tip contacting the ground, and extending the vibratory rod's lifespan. The outer and inner guard edges on the limit plate effectively prevent the adhesion of uncured concrete, reducing equipment cleaning workload and lowering maintenance costs.

[0028] 4. Diverse Functionality Expands Construction Scenarios

[0029] The device overcomes the limitations of a single insertion hole. After the vibrating rod moves upward and detaches from the limiting plate, the limiting plate can be directly used as a planar vibrating tool, achieving "two uses in one device." This reduces the types of construction equipment to carry and improves on-site operational flexibility. The strip groove design not only provides space for the lateral movement of the vibrating rod but also adapts to the needs of different hole spacings. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] See Figure 1 and Figure 2 The illustrated modified concrete grouting vibration type double-headed auger includes,

[0040] An upper frame 1 is provided, and a drive rod 2 is rotatably mounted inside the upper frame 1 via a bearing. One end of the drive rod 2 extends to the outside of the upper frame 1, and a handle 21 is installed at this end. The drive rod 2 has two drive threads 22 with opposite directions of rotation. A support block 3 is welded to the middle position of the upper frame 1. A through hole 31 is transversely passed through the side of the support block 3, which is fitted with the drive rod 2 with a clearance fit.

[0041] Two sliding blocks 4 are provided, both located inside the upper frame 1 and each engaging with a section of the drive thread 22. The rotation of the sliding blocks 4 is limited by the inner wall of the upper frame 1, so that the sliding blocks 4 can only move laterally along the upper frame 1. The interior of the sliding blocks 4 is provided with a nut 41 that engages with the drive thread 22. A vibrating rod 42 is fixed at the bottom of the sliding blocks 4. The lower end of the vibrating rod 42 is a pointed tip. A vibrating motor 43 is installed on the side of the vibrating rod 42 near the top. In the above technical solution, each vibrating rod 42 is paired with a small vibrating motor 43. Each vibrating motor 43 is independently controlled and powered by an external power supply. The vibration force generated by the vibrating motor 43 is directly transmitted to the vibrating rod 42, so that the lower end of the vibrating rod 42 is inserted into the unconsolidated concrete.

[0042] The support rod 5 is fixed to the top of the support block 3 by a fastener (the fastener is a flange), and a second handle 51 is provided on the outer wall of the support rod 5 near the top.

[0043] The limiting device 6 has an adjustable distance from the upper frame 1. The lower end of the vibration rod 42 passes through the limiting device 6 and contacts the ground plane through the limiting device 6.

[0044] In the above technical solution, the depth to which the vibrating rod 42 is inserted into the concrete can be adjusted by adjusting the distance between the limiting device 6 and the upper frame 1.

[0045] When the device is not in use, the limiting device 6 can be moved downward so that the height of the vibrating rod 42 is higher than the limiting device 6, so that the device can be placed on the ground.

[0046] See Figure 2 As shown, a shock-absorbing grip sleeve 551 is fitted onto the second handle 51.

[0047] The shock-absorbing grips are made of EVA material, which has a good vibration absorption effect, so as to reduce the transmission of vibration force to the hand when plugging in.

[0048] See Figure 1 , Figure 2 and Figure 3 As shown, the limiting device 6 includes a limiting plate 61, a guide rod 62, and an adjusting device 63. The limiting plate 61 is arranged parallel to the lower part of the upper frame 1, and the distance between the limiting plate 61 and the upper frame 1 is adjustable. Multiple guide rods 62 are provided. A guide plate 121 is provided on the outer side of the upper frame 1. The guide plate 121 is provided with holes (not shown) for the guide rods 62 to pass through. The guide rods 62 slide along the axial direction of the holes. A strip groove 64 is provided on the surface of the limiting plate 61. The vibrating rod 42 passes through the strip groove 64 and can slide laterally along the strip groove 64. A base 65 is fixedly provided at the middle position of the strip groove 64. The base 65 corresponds to the support block 3. The adjusting device 63 is installed between the support block 3 and the base 65.

[0049] In the above technical solution, the guide rod 62 and the guide plate 121 cooperate to guide the movement of the limiting plate 61, ensuring that the limiting plate 61 is always parallel to the upper frame 1. The spacing between the guide rods 62 needs to be greater than the size of the vibration motor 43 to avoid affecting the lateral displacement of the vibration rod 42.

[0050] The provided strip groove 64 is used to pass through the vibrating rod 42 and supports the lateral position adjustment of the vibrating rod 42.

[0051] The position of the limiting plate 61 can be adjusted by the adjusting device 63 to achieve the technical effect of adjusting the insertion depth of the vibrating rod 42.

[0052] The limiting plate 61 makes large-area contact with the unconsolidated concrete ground to ensure that it will not sink into the concrete quickly under the action of vibration when it reaches the ground. At the same time, it limits the insertion depth of the vibrating rod 42 to avoid both excessive and insufficient insertion depth.

[0053] Before inserting the pin, the position of the limiting plate 61 needs to be adjusted in advance, and the length of the vibrating rod 42 passing through the limiting plate 61 needs to be manually measured to ensure that the insertion depth is sufficient.

[0054] See Figure 2 As shown, the upper end of the guide rod 62 is threadedly connected to a limit cap 621. The limit cap provides a terminal limit for the downward movement of the guide rod. When the limit cap contacts the guide plate, the vibration rod moves to the top of the limit plate.

[0055] The setting of the limit cap 621 can prevent the limit plate 61 from moving downwards too far.

[0056] See Figure 1 , Figure 2 and Figure 3 As shown, the adjusting device 63 includes a bearing seat 631, a rotating tube 632, and a fixing rod 633. The bearing seat 631 is fixed to the top of the base 65. The rotating tube 632 is rotatably mounted in the bearing seat 631 via a bearing. The fixing rod 633 is fixed to the bottom of the support block 3. The fixing rod 633 has an external threaded portion machined on its exterior. The rotating tube 632 has an internal thread machined at its opening to mate with the external threaded portion. The rotating tube 632 and the fixing rod 633 are threadedly engaged. A rotating ring 634 is provided near the top of the rotating tube 632. A connecting rod 635 is fixed between the rotating ring 634 and the rotating tube 632.

[0057] In the above technical solution, by applying a rotational torque to the rotating ring 634, the rotating tube 632 rotates, thereby changing the threaded engagement position and realizing the position adjustment of the rotating tube 632 relative to the fixed rod 633, thus realizing the position adjustment of the limiting plate 61.

[0058] See Figure 3 As shown, an outer retaining edge 661 is provided at the top edge of the limiting plate 61, and an inner retaining edge 662 is provided at the top of the limiting plate 61, located at the edge of the strip groove.

[0059] In this device, when the vibrating rod 42 moves upward to disengage from the limiting plate 61, the limiting plate 61 can be used as a planar vibrator.

[0060] The outer edge 661 and the inner edge 662 can prevent uncured concrete from adhering to the top of the limiting plate 61.
