Description

Technical Field

[0001] This invention belongs to the technical field of bridge construction equipment, specifically a template-attached vibratory compaction device and its usage method. Background Technology

[0002] Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, bridges have also been extended to refer to buildings that cross mountains, adverse geological conditions, or meet other transportation needs to make travel more convenient. Currently, during the hardening process of concrete, in order to better remove air bubbles mixed inside, it is necessary to insert a vibrator to remove the air inside by vibration, thereby increasing the density of the hardened concrete.

[0003] However, in the current technology, when constructing large components such as bridges, the concrete beams to be poured at the same time are tens of meters long. The existing vibrator has a simple structure and a small vibration coverage area. It is necessary to constantly change the position of the vibrator, which leads to uneven mixing of concrete and easy generation of air bubbles. At the same time, during the construction of concrete beams, the vibrator is prone to hitting the tensioned steel strands, which poses a great safety hazard. Moreover, if multiple vibrators are used at the same time, the difference in vibration amplitude will cause the concrete aggregate to accumulate and segregate. If only one vibrator is used, it needs to be constantly moved and inserted, which takes a long time and wastes manpower and resources. Summary of the Invention

[0004] The purpose of this invention is to provide a formwork-attached vibratory compaction device and its usage method that can improve the concrete mixing effect, effectively prevent the generation of air bubbles, and avoid affecting the construction structure.

[0005] The technical solution adopted in this invention is as follows: A template-attached vibratory compaction device, comprising: a functional mechanism, the functional mechanism including a bottom frame, a limiting component, and a linkage component; the top frame of the bottom frame has an installation groove; an installation frame is embedded inside the installation groove; three limiting frames are equidistantly fixedly connected to the outer surface of the installation frame; the limiting component is disposed on the three limiting frames; and the linkage component is disposed on the limiting component; and

[0006] A moving mechanism includes an adjusting frame. Limiting openings are formed on both sides of the top center of the adjusting frame. A first bidirectional threaded rod is rotatably connected between the two sides of the adjusting frame relative to its inner surface. Two first adjusting blocks are threadedly connected to the outer surface of the first bidirectional threaded rod. Each first adjusting block extends into a corresponding limiting opening at its top. A support shaft is rotatably connected to one side of the outer surface of each first adjusting block. A second bidirectional threaded rod is rotatably connected between the adjusting frame and its inner surface. One end of the second bidirectional threaded rod slides through one side of the outer surface of the two first adjusting blocks. Two second adjusting blocks are threadedly connected to the outer surface of the second bidirectional threaded rod. Each second adjusting block extends into a corresponding limiting opening at its top. A support shaft is also rotatably connected to one side of the outer surface of each second adjusting block. A support wheel is slidably sleeved on the outer surface of each support shaft. A limiting groove is formed on one side of the outer surface of each support wheel. An adjusting spring is slidably sleeved on the outer surface of each support shaft within a corresponding limiting groove. One end of the first bidirectional threaded rod slides through one side of the outer surface of the two second adjusting blocks.

[0007] The bottom frame is rotatably connected to two corners, and the mounting frame has sliding holes on the bottom surface near the four corners.

[0008] The limiting components are provided in three sets, and each set of the limiting components includes a limiting rod. There are two limiting rods, and the two limiting rods are fixedly connected between the inner walls of the corresponding limiting frame on both sides.

[0009] Each of the limiting rods has two limiting springs slidably sleeved on its outer surface, and the six limiting rods are divided into three groups.

[0010] The linkage component includes support rods and linkage blocks. There are four support rods in total, and the lower end of each support rod is slidably inserted into the corresponding sliding hole. A movable plate is threadedly connected between the outer surfaces of the four support rods. A vibration motor is fixedly connected to the top of the movable plate. There are three linkage blocks in total, and each linkage block is slidably sleeved between the outer surfaces of a corresponding set of two limit rods.

[0011] Each of the support rods has a support spring slidably sleeved on its outer surface. The top end of each support spring is fixedly connected to the bottom of the moving plate, and the bottom end of each support spring is connected to the ground inside the mounting frame.

[0012] One of the linkage blocks has an extension block fixedly connected to its bottom, and an extension rod fixedly connected to one side of the outer surface of the extension block. A first abutment is inserted into the top of the extension rod near one end edge. A top frame is fixedly connected between the tops of the other two linkage blocks, and a mounting bracket is fixedly connected to the top of the top frame.

[0013] The mounting bracket is fixedly connected to a clamping frame at its top, and a second abutment is slidably embedded in the top of the clamping frame. A threaded hole is provided at the bottom end of the second abutment.

[0014] The threaded hole is internally threaded with an adjusting bolt, the outer surface of the adjusting bolt is slidably fitted with a linkage spring, and the bottom end of the adjusting bolt is fixedly connected with an elastic washer.

[0015] A method for using a template-attached vibratory compaction device includes the following steps:

[0016] S1. Installation and Adjustment: By rotating the first bidirectional threaded rod and the second bidirectional threaded rod, the first bidirectional threaded rod can be moved to adjust the position between the two first adjusting blocks. At the same time, the second bidirectional threaded rod can be moved to adjust the position between the two second adjusting blocks. This allows the moving mechanism to meet the spacing of different distribution beam bodies. The equipment is then moved intermittently to both sides of the bottom steel formwork body by the steering wheel and support wheel. By rotating the support rod, the height of the moving plate can be adjusted. The height of the extension block can be adjusted by the moving plate. The height of the first abutment can be effectively adjusted by the extension rod. The first abutment can fit against the bottom of the bottom steel formwork body. By rotating the adjusting bolt, the adjusting bolt can be locked inside the side steel formwork body by the elastic pad and the second abutment. This allows the equipment to be attached to one side of the corresponding side steel formwork body.

[0017] S2. Control and Adjustment: By controlling the start of the vibration motor, the vibration motor can drive the extension rod and the top frame to vibrate through the moving plate and the connecting block. This allows the extension rod to provide a vibration effect to the distribution beam body through the first abutment, while the top frame can provide a vibration effect to the side steel formwork body through the connecting spring, the second abutment, and the adjusting bolt. This allows the staggered equipment to simultaneously vibrate and mix the concrete between the bottom steel formwork body and the side steel formwork body.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In this invention, during use, by rotating the first bidirectional threaded rod and the second bidirectional threaded rod, the rotating first bidirectional threaded rod can effectively move and adjust the position between the two first adjusting blocks, and simultaneously, the rotating second bidirectional threaded rod can effectively move and adjust the position between the two second adjusting blocks. This allows the moving mechanism to accommodate different spacing of the distribution beam bodies. Furthermore, the steering wheels and support wheels effectively move the equipment intermittently to both sides of the bottom steel formwork body. By rotating and adjusting the support rod, the height of the moving plate can be effectively adjusted, which in turn allows the height of the extension block to be effectively adjusted. The extension block can then effectively adjust the height of the first abutment rod, ensuring that the first abutment rod effectively fits against the bottom of the bottom steel formwork body. Rotating the adjusting bolt allows it to be engaged inside the side steel formwork body via elastic pads and a second abutment. This enables the equipment to effectively attach to the corresponding side of the steel formwork body. Controlling the start of the vibration motor then drives the extension rod and top frame to vibrate via a moving plate and connecting block. The extension rod, through the first abutment, effectively provides vibration to the distribution beam body. Simultaneously, the top frame, through the connecting spring, the second abutment, and the adjusting bolt, provides vibration to the side steel formwork body. This allows the staggered placement of the equipment to simultaneously vibrate and mix the concrete between the bottom and side steel formwork bodies, effectively preventing any impact on the construction structure during concrete mixing and enabling the equipment to efficiently perform its intended functions.
