Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a high-frequency vibrator for flat bridge construction. Background Technology

[0002] Flatbed bridges, as an important transportation facility, are commonly used to cross obstacles such as rivers, culverts, and railways. In urban construction and road renovation, the construction plan for flatbed bridges is crucial. Construction requires a significant amount of materials, such as steel plates, concrete, and bolts. Especially when using precast concrete bridge components, high-frequency vibrators are necessary. High-frequency vibrators are primarily used for precast railway, highway, and road bridge components, as well as other precast concrete engineering structures. Their vibration frequency is more than three times higher than that of ordinary vibrators, resulting in smoother surfaces and significantly reduced air bubbles and voids in the vibrated components. This saves costs, accelerates project progress, and improves project quality.

[0003] Existing high-frequency vibrators are generally bolted to the precast mold of the bridge during use. They drive the precast mold to vibrate by their own vibration. However, the frequency of the high-frequency vibrator is higher than that of a regular vibrator. Therefore, the bolt will be subjected to violent and prolonged vibration. Frequent vibration can cause tiny gaps or even deformation in the originally tightly meshed threads, resulting in the bolt loosening and the vibrator falling off the mold.

[0004] Existing high-frequency vibrators mainly consist of a high-frequency vibrating motor and a high-frequency inverter cabinet. The high-frequency vibrating motor and the high-frequency inverter cabinet are connected by cables. This means that the cables are always in contact with the ground and generate friction when the vibrator is working, which can easily lead to cable damage or even leakage. At the same time, the construction environment of bridges is relatively complex, with people coming and going, and construction personnel or machinery can easily press on the cables, thereby causing cable damage and reducing the service life of the cables. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-frequency vibrator for flat bridge construction, which has the advantages of preventing bolt loosening and protecting the vibrator cable, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a high-frequency vibrator for flat bridge construction, comprising a base plate, a vibration motor, a connecting plate, and bolts respectively disposed on the upper surface of the base plate, the vibration motor being fixedly mounted on the upper surface of the connecting plate, and four bolts, the upper surface of the base plate having four threaded holes corresponding to the four bolts, the interior of the base plate having four rectangular slots communicating with the four threaded holes respectively, a cable being disposed at one end of the vibration motor, a limiting mechanism for limiting the bolts being disposed in each of the four rectangular slots, and a protective mechanism being disposed on the outer surface of the cable.

[0007] By using the above technical solution to limit the bolts, the bolts are prevented from loosening due to prolonged operation of the vibratory motor, thus preventing them from falling off the connecting plate. Subsequently, the vibratory motor can use a protective mechanism to protect the cable during operation, preventing the cable from being in contact with the ground for a long time and causing friction, which could lead to cable damage and affect the normal use of the vibratory motor, effectively increasing the service life of the cable.

[0008] Preferably, the limiting mechanism includes an annular plate disposed inside each of the four rectangular grooves. The annular plate can slide up and down within the rectangular grooves. The inner surface of the annular plate is provided with an internal thread section adapted to the bolt. The outer surface of the annular plate is rotatably mounted with two connecting rods arranged in a circular array. Sliding grooves are provided on both sides of the inner wall of the rectangular grooves. A sliding plate is rotatably mounted on one end of each of the two connecting rods. The two sliding plates can slide in the two sliding grooves respectively. Both sliding plates are provided with openings. Limiting elements for limiting the sliding plates are provided in the two sliding grooves.

[0009] By using the above technical solution to limit the bolts, the bolts can be prevented from loosening due to the vibration motor working for a long time, thus preventing the bolts from falling off the connecting plate.

[0010] Preferably, the protective mechanism includes a protective sleeve fitted onto the outer surface of the cable. The outer surface of the protective sleeve is provided with an installation plate and a limiting plate. On the opposite side of the installation plate and the limiting plate, a limiting block and a connecting groove are respectively provided. The limiting block is engaged in the connecting groove. The protective sleeve, the installation plate, the limiting plate, and the limiting block are all made of elastic material.

[0011] By adopting the above technical solution to protect the cable, the cable is prevented from being in contact with the ground for a long time and causing friction, which would lead to cable damage and affect the normal use of the vibration motor, thus effectively increasing the service life of the cable.

[0012] Preferably, the limiting member includes a slot formed inside the slide groove, a vertical limiting rod is slidably inserted into the slot, and a spring is provided between the bottom of the slot and the bottom end of the limiting rod.

[0013] By employing the above technical solution to limit the sliding plate, the limiting plate is prevented from detaching from the sliding groove.

[0014] Preferably, two guide rods are symmetrically distributed and fixedly installed between the top and bottom of the rectangular groove, and both guide rods penetrate the annular plate.

[0015] The ring plate is guided by the above-mentioned technical solution.

[0016] Preferably, the outer surface of the protective sleeve is uniformly fitted with an elastic sleeve.

[0017] The above technical solution is used to prevent the limiting block from detaching from the connecting groove set on one side of the limiting plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The bolts are limited by a limiting mechanism to prevent them from loosening due to prolonged operation of the vibrating motor, which could cause them to fall off the connecting plate.

[0020] 2. The cable is protected by a protective mechanism to prevent it from being in contact with the ground for a long time and causing friction, which could lead to cable damage and affect the normal use of the vibration motor, thus effectively increasing the service life of the cable.

A vibrating motor 2, a connecting plate 3, and bolts 4 are respectively arranged on the upper surface of the base plate 1. The vibrating motor 2 is fixedly installed on the upper surface of the connecting plate 3. There are four bolts 4. The upper surface of the base plate 1 has four threaded holes 5 corresponding to the four bolts 4. The interior of the base plate 1 has four rectangular grooves 6, which are respectively connected to the four threaded holes 5. A cable 7 is provided at one end of the vibrating motor 2. Each of the four rectangular grooves 6 is provided with a limiting mechanism for limiting the bolts 4. A protective mechanism is provided on the outer surface of the cable 7.

[0034] Please see Figure 3 , Figure 4 , Figure 5 and Figure 9The limiting mechanism includes annular plates 8, each set inside one of four rectangular slots 6. The annular plates 8 can slide up and down within the rectangular slots 6. The inner surface of the annular plates 8 is provided with an internal thread section 9 that is compatible with the bolts 4. The outer surface of the annular plates 8 is arranged in a circular array and rotatably mounted with two connecting rods 10. Sliding grooves 11 are provided on both sides of the inner wall of the rectangular slots 6. A sliding plate 12 is rotatably mounted on one end of each of the two connecting rods 10. The two sliding plates 12 can slide in the two sliding grooves 11 respectively. A through opening 13 is provided on each of the two sliding plates 12. Limiting elements for limiting the sliding plates 12 are provided in the two sliding grooves 11.

[0035] Please see Figures 6-7 The protective mechanism includes a protective sleeve 15 that is fitted onto the outer surface of the cable 7. The outer surface of the protective sleeve 15 is provided with a mounting plate 16 and a limiting plate 17. On the opposite side of the mounting plate 16 and the limiting plate 17, a limiting block 18 and a connecting groove 19 are respectively provided. The limiting block 18 is snapped into the connecting groove 19. The protective sleeve 15, the mounting plate 16, the limiting plate 17 and the limiting block 18 are all made of elastic material.

[0036] Please see Figure 9 The limiting component includes a slot 20 opened inside the slide groove 11, a vertical limiting rod 21 is slidably inserted into the slot 20, and a spring 22 is provided between the bottom of the slot 20 and the bottom end of the limiting rod 21.

[0037] Please see Figure 8 Two guide rods 23 are symmetrically distributed and fixedly installed between the top and bottom of the rectangular groove 6. Both guide rods 23 penetrate the annular plate 8. The guide rods 23 are used to guide the annular plate 8 and prevent the annular plate 8 from rotating in the rectangular groove 6 along with the bolt 4.

[0038] Please see Figure 6 The outer surface of the protective sleeve 15 is uniformly fitted with an elastic sleeve 24. The elastic sleeve 24 can prevent the limiting block 18 from detaching from the connecting groove 19 provided on one side of the limiting plate 17. In addition, the elastic sleeve 24 can also be replaced by a cable tie.

[0039] Working principle: In use, first place the vibratory motor 2 and the connecting plate 3 on the base plate 1. Then, pass the bolt 4 through the connecting plate 3 and thread it into the threaded hole 5 on the base plate 1. As the bolt 4 moves downward in the threaded hole 5, it will pass through the threaded hole 5 and enter the rectangular groove 6, contacting the internal thread section 9 on the inner surface of the annular plate 8. Continue to rotate the bolt 4. At this time, the annular plate 8 will rise along the bolt 4, and at the same time, it will drive the connecting rod 10 to rotate around the outer surface of the annular plate 8 and gradually tend to be horizontal. As the connecting rod 10 rotates and tends to be horizontal, it will cause the connecting rod 10 to rotate around the outer surface of the annular plate 8 and gradually tend to be horizontal. When the sliding plate 12 slides to the deepest part of the groove 11, the inclined surface at one corner of the sliding plate 12 pushes the limiting rod 21 downward in the slot 20 and compresses the spring 22. When the sliding plate 12 has completely passed the limiting rod 21, the rebound force generated by the spring 22 pushes the limiting rod 21 upward, so that the top of the limiting rod 21 is inserted into the through 13, thereby limiting the sliding plate 12. The sliding plate 12 limits the annular plate 8, and the annular plate 8 limits the bolt 4, and vice versa.

[0040] When it is necessary to protect the cable 7, the protective sleeve 15 can be fitted onto the outer surface of the cable 7. Then, the limiting block 18 set on one side of the mounting plate 16 can be engaged into the connecting groove 19 set on one side of the limiting plate 17 to achieve protection of the cable 7. Finally, the elastic sleeve 24 can be fitted onto the protective sleeve 15.
