Description

Technical Field

[0001] This utility model relates to the field of concrete structure construction technology, specifically to a vibratory compaction device for pier construction. Background Technology

[0002] With the continuous acceleration of urbanization in my country, the construction of highways, railways and municipal infrastructure has developed rapidly. Most of these construction projects involve bridge construction. Concrete is one of the main materials used in the construction process, and its concrete components are the most important load-bearing components of the building structure. A crucial part of concrete structure construction is the pouring of cement piers. When pouring cement piers, they must be vibrated to ensure compaction. Air bubbles should be strictly avoided on the inside and outside surfaces of the piers, otherwise the load-bearing capacity of the piers will be seriously affected.

[0003] Patent application number 202323088991.7, entitled "A Vibration System for Concrete Pier Column Pouring," describes an invention that, through the cooperation of a lifting component, a tremie pipe component, a connecting platform, a rotating component, and a vibration mechanism, can achieve automatic vibration operation during the pouring of cement pier columns. The device is mechanically driven and does not require manual handling, solving the problems associated with manual vibration. This makes the working environment more comfortable and safer for employees during the pouring of cement pier columns, and significantly improves construction efficiency and vibration effect. However, before the pier column is poured, a steel reinforcement frame is erected, and the diameter of the steel reinforcement frame is smaller than the diameter of the pier column to be poured. Due to the obstruction of the steel reinforcement frame, the vibrator cannot extend to areas outside the steel reinforcement frame, where there is also concrete that needs to be vibrated. This may result in incomplete vibration at the edge of the pier column, thereby reducing the quality of the pier column pouring. Utility Model Content

[0004] This invention provides a vibratory device for pier construction to solve the problem that existing vibratory devices cause incomplete vibration in the edge area of ​​the pier due to obstruction by the steel reinforcement frame.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A vibratory device for pier construction includes a vibratory device installed on the upper end of the steel reinforcement frame of the pier. The vibratory device includes a lifting component, a tremie cylinder installed at the lower end of the lifting component, and a connecting platform installed at the lower end of the tremie cylinder. The connecting platform is provided with a slewing mechanism, a horizontal telescopic mechanism installed on the rotating platform of the slewing mechanism, and a vibratory mechanism installed at the telescopic end of the horizontal telescopic mechanism. The vibratory mechanism includes several traction components and a vibratory rod suspended on the traction components. The vibratory rod includes a main vibratory rod and several auxiliary vibratory rods. The main vibratory rod has a cavity inside, and a sliding rod is provided inside the cavity. Several telescopic rods are provided on the side wall of the sliding rod. Several through holes communicating with the cavity are opened on the side wall of the main vibratory rod. One end of the auxiliary vibratory rod passes through the through holes and is rotatably connected to the end of the telescopic rod. The auxiliary vibratory rod is rotatably connected to the side wall of the through holes.

[0007] Before pouring concrete for the piers, steel frames are erected, and the diameter of these frames is always smaller than that of the piers being poured. Due to the obstruction of the steel frames, the vibrator cannot extend beyond the areas outside the frames, where concrete still needs to be vibrated. This can lead to incomplete vibration at the edges of the piers, thus reducing the quality of the pier pouring. Therefore, by using sliding and telescopic rods, the secondary vibrator is rotated to be perpendicular to the primary vibrator, allowing it to extend laterally and transmit vibration. Simultaneously, the lateral extension of the secondary vibrator allows it to pass through holes in the steel frame, transmitting vibration to the outside of the pier. This solves the problem of incomplete vibration on the outer side of the pier and improves the quality of the pier pouring.

[0008] Furthermore, the telescopic end of the horizontal telescopic mechanism is provided with an elastic element, and a limiting hole is formed on the elastic element, into which the vibrating rod is embedded.

[0009] The limiting hole allows the vibrator to move along with the horizontal telescopic mechanism and the rotary mechanism. At the same time, the elastic force of the elastic element provides a buffer force for the vibrator, reducing the impact of the vibrator's vibration on the horizontal telescopic mechanism and the rotary mechanism.

[0010] Furthermore, a groove is provided on the side wall of the limiting hole, and a slide rail is provided on the outer side wall of the vibrating rod. The slide rail is matched and installed with the groove, and the orientation of the slide rail is opposite to the orientation of the secondary vibrating rod.

[0011] Since the secondary vibrating rod only faces one direction of the vibrating rod, and the vibrating rod is hoisted onto the traction component, the vibrating rod will inevitably rotate circumferentially during the vibration process, causing the orientation of the secondary vibrating rod to change. Therefore, by matching the slide rail with the groove, the orientation of the secondary vibrating rod is positioned so that it always faces the outside of the pier column, making it easier for the secondary vibrating rod to pass through the hole of the steel reinforcement frame.

[0012] Furthermore, the hoisting component, the tremie cylinder, the connecting platform, the slewing mechanism, the horizontal telescopic mechanism, and the vibrating mechanism are all provided with concrete channels in the middle.

[0013] The lifting components, tremie pipe, connecting platform, slewing mechanism, horizontal telescopic mechanism and vibration mechanism installed on the top of the movable template work together to complete the automatic vibration operation during the pier pouring. The mechanical drive device replaces manual operation, which solves the problems of manual hand vibration. This makes the working environment of employees more comfortable and safer during the pouring of cement piers, and greatly improves construction efficiency and vibration effect.

[0014] Furthermore, a sealing sleeve is provided at the connection between the auxiliary vibration rod and the through hole.

[0015] Because the vibrator operates within concrete, concrete can easily seep into the holes in the main vibrator. Once the concrete hardens, it restricts the rotation of the secondary vibrator, causing the vibrator to lose its proper function. Therefore, a sealing sleeve is used to seal the holes between the main and secondary vibrators to prevent concrete from entering, ensuring a suitable rotation environment for the secondary vibrator and extending its service life.

[0016] Furthermore, it also includes a climbing device installed on the pier and a movable formwork installed on the outside of the steel reinforcement frame. The upper end of the movable formwork is equipped with a vibrating device for extending into the movable formwork for vibration, and the lower end of the movable formwork is equipped with a climbing device for supporting the movable formwork.

[0017] By installing a climbing device on the pier base, the movable formwork and vibrating device can be lifted onto the pier, allowing for continuous pier pouring without dismantling the device. This reduces the need for frequent disassembly and installation of the vibrating device, effectively shortening the pier construction cycle. Furthermore, when the pier is high, the installation and dismantling of the vibrating device and pier formwork becomes more difficult and less safe. The climbing device eliminates the need for manual operation and frequent installation and dismantling, improving construction safety and reducing the difficulty of high-altitude construction.

[0018] Furthermore, the climbing device includes an upper clamp, a lower clamp, and a hydraulic cylinder mounted on the lower clamp for pushing the upper clamp upward. The upper end of the upper clamp is connected to the movable template.

[0019] The lower clamp is fastened to the pier, the upper clamp is loosened, and the upper clamp is pushed up by the hydraulic cylinder. Then the upper clamp is fastened to the pier, the lower clamp is loosened, the hydraulic cylinder retracts, and the lower clamp is pulled up. This process is repeated to achieve automatic climbing of the climbing device, which also drives the movable template and the vibrating device to climb together. The device has a simple structure and operation and can be remotely controlled.

[0020] Furthermore, both the upper clamp and the lower clamp include several detachable connecting plates and at least two locking devices. The two ends of the locking devices are rotatably connected to the detachable connecting plates, and the two ends of the detachable connecting plates are respectively rotatably connected to another detachable connecting plate and / or locking device.

[0021] Since the pier can be cylindrical or prismatic, to ensure the upper and lower clamps are securely fastened to the pier, their shapes must be roughly the same as or similar to the pier's shape. Therefore, by replacing different detachable connecting plates, the inner walls of the upper and lower clamps are made to fit as closely as possible to the outer wall of the pier. Then, by tightening and loosening the locking device, the circumference of the upper and lower clamps is changed, allowing them to tighten or loosen from the pier. This achieves the tightening and loosening of the upper and lower clamps, and the upper and lower clamps work together to enable the climbing device to ascend.

[0022] Furthermore, the detachable connecting plate includes an arc-shaped plate and a straight plate. The arc-shaped plate matches the sidewall of the cylindrical pier, while the straight plate matches the sidewall of the prismatic pier.

[0023] Furthermore, the movable template is equipped with a construction platform at its upper end, and a guardrail is provided on the outside of the construction platform. This facilitates construction workers in standing and installing or dismantling the device, improving safety.

[0024] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0025] (1) The auxiliary vibrating rod is rotated to be perpendicular to the main vibrating rod by means of the sliding rod and the telescopic rod, so that the auxiliary vibrating rod extends to the side and transmits the vibration. At the same time, the auxiliary vibrating rod extending to the side can pass through the holes on the steel frame and transmit the vibration to the outside of the pier column, thereby solving the problem of incomplete vibration on the outside of the pier column and improving the quality of pier column casting.

[0026] (2) By matching the slide rail with the groove, the orientation of the auxiliary vibrating rod is positioned so that it always faces the outside of the pier column, making it easier for the auxiliary vibrating rod to pass through the hole of the steel frame;

[0027] (3) The lifting components, cistern, connecting platform, slewing mechanism, horizontal telescopic mechanism and vibration mechanism installed on the top of the movable template cooperate with each other to complete the automatic vibration operation during the pier pouring. The mechanical drive device replaces manual operation, which solves the problem of manual hand vibration. This makes the working environment of employees more comfortable and safer during the cement pier pouring, and greatly improves the construction efficiency and vibration effect.

[0028] (4) By installing a climbing device on the pier base, the movable template and vibrating device are lifted on the pier, so that the pier can be continuously poured without removing the device, reducing the frequent disassembly and installation of the vibrating device, which can effectively reduce the construction cycle of the pier. At the same time, when the pier is high, the installation and disassembly of the vibrating device and the pier template will be more difficult and the safety will be worse. By lifting with the climbing device, no staff operation is required, and frequent installation and disassembly are not required, which improves the safety of construction and reduces the difficulty of high-altitude construction.

[0029] (5) The lower clamp is fastened to the pier, the upper clamp is loosened, the upper clamp is pushed up by the hydraulic cylinder, the upper clamp is fastened to the pier again, the lower clamp is loosened, the hydraulic cylinder is contracted, and the lower clamp is pulled up. This process is repeated to achieve automatic climbing of the climbing device, while driving the movable template and the vibrating device to climb together. The device has a simple structure and operation and can be remotely controlled. Attached Figure Description

The auxiliary vibrating rod 213 is rotatably connected to the side wall of the through hole 217.

[0040] The number of auxiliary vibrating rods 213 is determined by the degree and length of the main vibrating rod 212, and they are evenly distributed along the main vibrating rod 212. Preferably, the distance between two adjacent auxiliary vibrating rods 213 corresponds to the holes on the steel frame. The main vibrating rod 212 contains only a vibrating motor. The sliding rod 215 is also driven up and down by a built-in drive motor. The number of telescopic rods 216 is equal to that of the auxiliary vibrating rods 213 and they correspond one-to-one. They are also driven to extend and retract by a built-in motor.

[0041] The lifting component 201 preferably drives the steel wire ropes via an angle reduction motor to lift and lower the connecting platform 203. At least two steel wire ropes are provided, both connected to the connecting platform 203. The steel wire ropes are driven by a reel connected to the output shaft of the angle reduction motor and by pulleys to change direction, thus achieving upward traction of the connecting platform 203. The tremie drum 202 is arranged along the concrete channel 207 to facilitate lifting and lowering with the vibrating device 2. The tremie drum 202 is preferably a telescopic structure, including multiple telescopic drums and support rods, which are nested together. The number of telescopic drums can be adjusted according to height requirements. Its function is to guide the concrete and prevent segregation. The telescopic drums have a conical structure, which allows them to overlap during retraction, saving space. Through holes are provided on the support rods for the steel wire ropes to pass through, guiding and limiting the telescopic drums.

[0042] In a more preferred embodiment, the telescopic end of the horizontal telescopic mechanism 205 is provided with an elastic element 210, and a limiting hole 211 is provided on the elastic element 210, and the vibrating rod 209 is embedded in the limiting hole 211.

[0043] To buffer and guide the lateral movement of the vibrator 209, an elastic element 210 is provided on the moving end of the horizontal telescopic mechanism 205. The elastic element 210 preferably includes a spring bracket, a support spring, and a threaded rod. There are two threaded rods and two support springs. The two threaded rods are symmetrically fixed on both sides of the spring bracket. The two support springs are respectively fitted onto the upper part of the two threaded rods.

[0046] The rotating mechanism 204 enables rotation between the tremie drum 202 and the vibrating device 2.

Two horizontal telescopic mechanisms 205 on the same side are fixedly connected and welded to the connecting platform 203. When the two sets of horizontal telescopic mechanisms 205 extend, the two vibrators 209 can reach the vicinity of the steel frame at the edge of the pier. When the two sets of horizontal telescopic mechanisms 205 shorten, the two vibrators 209 are close together, and the distance between the two vibrators 209 is less than the sum of the distances that their vibrations can be transmitted. That is, the radiation range of the two vibrators 209 vibrating at the same time covers the center of the pier. With the rotation drive of the rotary mechanism 204, the two vibrators 209 can rotate and move 360 ​​degrees. The traction component 208 makes the vibrators 209 vertically adjustable.
