Description

Technical Field

[0001] This utility model relates to the field of vibration equipment technology, and in particular to an easily movable attached vibration device suitable for the side of beam structures. Background Technology

[0002] In engineering fields such as construction, water conservancy, and pumped storage, side vibration of beam structures is a crucial step in ensuring the quality of concrete construction. Currently, the mainstream side vibration methods for beam structures in the industry mainly rely on attached vibrators and immersion vibrators. Attached vibrators are usually directly fixed to the outside of the formwork with bolts, and vibration can be started simply by connecting the power supply.

[0003] However, this traditional technical solution has significant limitations: on the one hand, in order to achieve effective vibration of all sides of the beam structure, multiple vibrators need to be installed on the formwork, which leads to a significant increase in the equipment procurement and usage costs for the work team. This solution is only suitable for large-scale precast beam construction scenarios and is difficult to adapt to the needs of small-batch, dispersed beam structure construction. On the other hand, in water conservancy and hydropower projects and mountain road construction, the number of beam structures is small and their distribution is scattered. At the same time, mountain roads are rugged and transportation conditions are poor, making the construction and operation of large-scale precast beam plants infeasible. If the traditional multi-vibrator fixing solution is still used, it will not only further increase construction costs, but also affect construction efficiency and quality due to difficulties in equipment transportation and complicated installation.

[0004] To address the aforementioned technical challenges and reduce equipment investment costs for construction units, this utility model provides a movable, attached vibratory compaction device suitable for the side of beam structures. With a detachable attached vibratory compactor installation structure, the vibrator can be moved as needed, completing the compaction requirements with fewer vibrators and effectively reducing construction costs. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a movable, attached vibratory compaction device suitable for the side of beam structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A movable, attached vibratory compaction device suitable for the side of a beam structure includes a vibrator body and an attachment frame for attaching the vibrator body. The vibrator body has an upper steel plate and a lower steel plate at its upper and lower ends, respectively. The lower steel plate and the upper steel plate each have at least one open pre-drilled hole on their opposite sides. The front end of the attachment frame has a support member corresponding to the lower steel plate. The lower steel plate engages with the corresponding support member through the pre-drilled hole. A locking bolt is detachably installed on the front side of the attachment frame near the upper end. The locking bolt rests in the pre-drilled hole of the upper steel plate and is locked by a self-locking nut.

[0007] Preferably, the upper end of the upper steel plate is bent forward.

[0008] Preferably, the front side of the attachment frame near the upper part is provided with a through hole, which is larger than the maximum diameter of the bolt. The lower end of the through hole is provided with a groove for the bolt shank to be inserted, and the groove corresponds to the reserved hole in the upper steel plate.

[0009] Preferably, the front side of the attachment frame near the lower end is provided with a U-shaped toe plate that surrounds the support member. The toe plate can accommodate the insertion of the lower steel plate, and the gap between the toe plate and the attachment frame is equal to the thickness of the lower steel plate.

[0010] Preferably, the upper end of the inner wall of the limiting frame is provided with a slope.

[0011] Preferably, the lower end of the attachment frame is provided with a U-shaped bracket, and the front crossbeam of the bracket abuts against the front side of the lower end of the vibrator body.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] Example 1: In order to solve the problems existing in the prior art, this example provides a movable attached vibratory device suitable for the side of a beam structure, including a vibrator body 9 and an attachment frame 1 for attaching and mounting the vibrator body 9.

[0026] The vibrator body 9 is a flat plate vibrator. The upper and lower ends of the vibrator body 9 are respectively provided with an upper steel plate 11 and a lower steel plate 10. The lower steel plate 10 and the upper steel plate 11 each have at least one open pre-reserved hole 12 on their opposite sides.

[0027] The front end of the attachment frame 1, near the lower end, is provided with a support member 2 that corresponds one-to-one with the lower steel plate 10. The support member 2 is a steel pipe welded and fixed to the attachment frame 1. The reserved hole 12 on the lower steel plate 10 can be mounted on the steel pipe serving as the support member 2 to form a snap-fit ​​connection. The front side of the attachment frame 1, near the upper end, is detachably equipped with a locking bolt 5. After the lower steel plate 10 of the vibrator body 9 is placed on the support member 2 through the reserved hole 12, the locking bolt 5 is placed in the reserved hole 12 of the upper steel plate 11, and the self-locking nut 6 is screwed onto the locking bolt 5. The self-locking nut 6 abuts against the front end of the upper steel plate 11. Through the cooperation between the lower steel plate 10 and the support member 2, and between the upper steel plate 11 and the bolt, the vibrator body 9 is locked onto the attachment frame 1.

[0028] Based on the above technical solution: According to the vibration point positions marked on the template, fix the back of the attachment frame 1 to the template (e.g., by welding or bolting). This is to fix the vibration point, and the attachment frame 1 serves as the fixed installation point, providing the installation foundation. Then, align the pre-drilled hole 12 of the lower steel plate 10 at the lower end of the vibrator body 9 with the support member 2 on the attachment frame 1, and slowly lower the vibrator so that the support member 2 is fully inserted into the pre-drilled hole 12 of the lower steel plate 10. At this time, the support member 2 supports the entire weight of the vibrator body 9, completing the initial fixation at the bottom. After that, insert the locking bolt 5 from the installation position near the upper part of the front side of the attachment frame 1, so that the bolt rod rests in the pre-drilled hole 12 of the upper steel plate 11. Adjust the bolt position to ensure that the vibrator body 9 and the attachment frame 1 are tightly fitted. Then, tighten the self-locking bolt from the end of the bolt to lock the upper part of the vibrator body 9, completing the installation and fixation of the entire vibrator. Connect the power socket and start the vibrator body 9 to vibrate the concrete at the vibration point (the vibration time and frequency are set according to the concrete grade and specifications). After vibration is completed, disconnect the power supply, then unscrew the self-locking bolts, remove the locking bolts 5, lift the vibrator body 9 upwards so that the reserved hole 12 of the lower steel plate 10 is disengaged from the support 2, move the vibrator to the next vibration point and repeat the above installation and vibration steps until the side vibration operation of the entire beam is completed.

[0029] By using the interlocking mechanism of "lifting component 2 + lower steel plate 10 pre-drilled hole 12" and the locking structure of "locking bolt 5 + upper steel plate 11 pre-drilled hole 12 + self-locking bolt", the vibrator body 9 and the attachment frame 1 can be quickly disassembled and stably fixed, ensuring that the vibrator does not loosen or shift during the vibration process. Only 2-3 vibrators are needed to complete the vibration operation of multiple vibration points in this project, which greatly reduces the equipment investment cost. At the same time, the vibrator is easy to move, and the construction efficiency will also be improved.

[0030] In this embodiment, the upper end of the upper steel plate 11 is bent forward. This folded edge structure can form a lateral obstruction for the locking bolt 5 placed in the reserved hole 12 of the upper steel plate 11, preventing the locking bolt 5 from slipping out along the opening direction of the reserved hole 12 due to equipment vibration during the vibration process.

[0031] In this embodiment, the attachment frame 1 has a through hole 7 near its upper front end. The through hole 7 is larger than the maximum diameter of the bolt. The lower end of the through hole 7 has a groove 8 for the bolt shank to be inserted into, and the groove 8 corresponds to the pre-drilled hole 12 in the upper steel plate 11. First, the shank of the locking bolt 5 is inserted through the through hole 7 of the attachment frame 1, allowing the bolt shank to naturally embed into the groove 8 below. At this point, the position of the locking bolt 5 is exactly aligned with the pre-drilled hole 12 in the upper steel plate 11. The bolt shank can then be directly placed into the pre-drilled hole 12, achieving a detachable fit between the locking bolt 5 and the attachment frame 1. During vibration, the groove 8 restricts the horizontal displacement of the locking bolt 5, further preventing the bolt from loosening. The vertical locking of the vibrator body 9 is limited by the locking preload of the locking bolt 5 and the self-locking nut 6, preventing easy displacement.

[0032] In this embodiment, the front side of the attachment frame 1, near its lower end, is provided with a U-shaped toe plate 3 that surrounds the lifting member 2. The width of the toe plate 3 is greater than the width of the lower steel plate 10 to allow the lower steel plate 10 to be inserted. The gap between the toe plate 3 and the attachment frame 1 is equal to the thickness of the lower steel plate 10, which prevents the front side of the lower steel plate 10 from being blocked. Combined with the locking action of the locking bolt 5 and the self-locking nut 6, the vibrator will not deviate in the horizontal front-back direction. The upper end of the inner wall of the limiting frame is provided with a ramp to facilitate the insertion of the lower steel plate 10.

[0033] In this embodiment, the lower end of the attachment frame 1 is provided with a U-shaped bracket 4, and the front crossbeam of the bracket 4 abuts against the front side of the lower end of the vibrator body 9. After the lower steel plate 10 is inserted into the toe plate 3 and the lifting member 2 is inserted into the reserved hole 12, the front side of the lower end of the vibrator body 9 is in contact with the front crossbeam of the bracket 4. The bracket 4 forms an upward supporting force on the front end of the vibrator, forming a two-point support structure with the rear end support of the lifting member 2. During vibration operation, the bracket 4 can counteract the downward pull force generated by the vibration at the front end of the vibrator, and is used to provide auxiliary support for the vibrator body 9 from the lower front side, effectively preventing the vibrator from tilting due to excessive force on the front end. At the same time, the two-point support structure distributes the weight load of the vibrator and extends the service life of the lifting member 2.

[0034] In this embodiment, a connector 14 is welded and fixed to the lower end of the back side of the attachment frame 1, and a rib plate 13 is welded and fixed to the upper end. The connector 14 and the rib plate 13 are fixedly connected to the template by bolts or welding. The connection point on the back side of the attachment frame 1 is extended by the rib plate 13 and the connector 14 to adapt to the template (the side of the vibration point installation part has a C-shaped structure).

[0035] In this embodiment, the lower steel plate 10 has two reserved holes 12, and the upper steel plate 11 has one reserved hole 12. The "2 lower, 1 upper" reserved hole 12 layout makes the fixing structure of the vibrator body 9 more reasonable and the force on the upper and lower parts more balanced.

[0036] Project Overview: The Jiufengshan Pumped Storage Power Station in Huixian County, Henan Province, is located in Huangshui Township, Huixian City, Xinxiang City. The power station is equipped with six vertical shaft single-stage mixed-flow reversible pump-turbines with a single unit capacity of 350MW, for a total installed capacity of 2100MW and a rated head of 682m. The project is classified as a large (1) type first-class project, with the main permanent buildings designed as Class 1 buildings and the secondary permanent buildings designed as Class 3 buildings.

[0037] The project mainly consists of Bridges 1 and 2 on Y4 Road. Due to road conditions, on-site pouring was chosen, using prefabricated steel formwork. The prefabricated steel formwork was fabricated in sections, composed of steel plates and shaped steel sections. The height of each section of the prefabricated steel formwork matched the height of the beam, with an average length of 1.6m (mainly for ease of processing and transportation). In order to achieve good appearance quality of the beam structure concrete, according to the construction plan, two attached vibrators need to be installed on each prefabricated steel formwork section.

[0038] According to the project, the beam is 32m long and 2m high. To facilitate transportation, installation, and disassembly, the segment length is 1.6m. An outer vibrator is arranged in the middle along the beam height, double-sided, with spacing consistent with the formwork segment length. First, the vibrator positions are marked on the steel formwork, and then the attachments are welded according to the marked positions. Next, a plate vibrator with a steel plate is installed. The lower structure of the plate vibrator is inserted into the gap of the toe plate 3 of the attachment frame 1. Then, the nutless end of a long bolt is inserted into the through hole 7, and the nut-equipped end is secured in the pre-drilled hole 12 on the upper part of the plate vibrator. The plate vibrator is fixed by tightening the nut. During concrete pouring, the vibrator is moved to vibrate multiple points of the entire beam structure. This device features low investment and high efficiency, achieving full vibration of the beam structure with fewer vibrators. It is particularly suitable for lateral vibration of beam structures produced outside of designated production sites. In particular, the construction of beam structures within pumped storage power station sites and small-scale projects is inconvenient to use large-scale prefabrication yards.
