Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a ride-on bridge deck wet joint vibration device, which is suitable for vibration after the bridge deck wet joint is poured. Background Technology

[0002] Currently, wired remote-controlled wet joint vibration damping machines are the most common type of vibration damping equipment for bridge deck wet joints. This type typically uses a variable frequency drive for its walking mechanism, mainly divided into direct-drive wheel type or tracked type. The spacing between the vibrating rods is usually not adjustable. Direct-drive wheel type machines mainly use two parallel tracks for movement, while tracked type machines can adapt to different terrains, but require more frequent adjustments to the driving direction when turning.

[0003] Since wet joints in bridge decks typically include transverse and longitudinal joints, this type of equipment has low efficiency in switching between the construction interfaces of transverse and longitudinal joints. Direct-drive vibration dampers cannot switch automatically and require external cranes or forklifts for assistance, which limits wet joint construction and reduces vibration efficiency. Furthermore, because the rebar spacing in wet joints varies across different bridge construction projects, this type of equipment is unsuitable for situations where the rebar spacing changes, demonstrating significant shortcomings in versatility and convenience.

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1, such as Figure 1 and Figure 2 As shown, a driverable bridge deck wet joint vibration device includes a traveling mechanism, a hydraulic mechanism and a vibration dissipation mechanism. The traveling mechanism is connected to the vibration dissipation mechanism through the hydraulic mechanism. A traveling drive wheel 10 is installed at the bottom of the traveling mechanism, and a driving steering wheel for driving the traveling drive wheel 10 is installed at the top of the traveling mechanism.

[0024] By adopting a drivable walking mechanism for the first time, steering is facilitated, operational flexibility and work efficiency are increased, and the efficiency of switching between transverse and longitudinal joint construction interfaces is improved. During implementation, a storage-type power supply can be used, featuring stepless speed regulation and a built-in steering mechanism, offering advantages such as flexible operation and environmental friendliness. The hydraulic mechanism is installed under the chassis of the walking mechanism, enabling fine-tuning and leveling lifting, and offering advantages such as high stability and good adjustability.

[0025] Specifically, the vibration reduction mechanism includes a vibration reduction machine chassis 4 and a vibratory rod positioning plate 5. The vibration reduction machine chassis 4 is connected to the traveling mechanism via a hydraulic mechanism.

The vibratory rod positioning plate 5 is mounted on top of the vibration reduction machine chassis 4, and the high-frequency vibratory rods 17 are installed in the vibratory rod positioning plate 5. The lifting height of the high-frequency vibratory rods 17 can be adjusted according to the depth of the wet joint, and the vibratory rod positioning plate 5 can be replaced according to different rebar spacings.

[0026] The top of the vibratory rod positioning plate 5 is also equipped with a lifting electric cylinder 14 and a connecting flange 15. The vibration dissipation mechanism also includes a frame that houses the vibratory rod positioning plate 5. The vibratory rod positioning plate 5 can be provided with multiple positioning slots at different intervals. The lifting electric cylinder 14 is installed on the top of the inner cavity of the frame, and the lifting electric cylinder 14 is placed vertically with its telescopic head facing downwards. The output end of the lifting electric cylinder 14 is connected to the connecting flange 15 for transmission. The bottom of the connecting flange 15 is fixedly connected to the vibratory rod positioning plate 5, and the bottom of the vibratory rod positioning plate 5 is connected to the high-frequency vibratory rod 17 through connecting bolts 16. The vibratory rod positioning plate 5 can be replaced and adjusted according to different rebar spacings. The vibratory rod positioning plate 5 is all bolted for easy replacement and has strong applicability.

[0027] Please see Figure 4 There are generally four types of rebar spacing in the wet joints of bridge decks: 200*100mm, 150*100mm, 150*150mm, and 200*150mm. Based on the rebar spacing, a corresponding vibratory rod positioning plate 5 is fabricated, and the positioning plate is bolted to the lifting connecting rod for quick replacement. The fabricated vibratory rod positioning plate 5 is shown below. Figure 4 As shown, the three frames in the upper and lower parts are the conveying and installation parts for the lifting electric cylinder 14 and the connecting flange 15. The vibratory rod positioning plate 5 has various types, and each type has high-frequency vibratory rod 17 positioning holes of different sizes according to the conventional vibration size. The positioning holes form positioning grooves with different spacings on the vibratory rod positioning plate 5, which facilitates the installation of high-frequency vibratory rods 17.

[0028] The bottom of the vibration decompression machine chassis 4 is equipped with vibration decompression machine traveling wheels 6. When the driving wheels 10 are moved, they drive the vibration decompression machine chassis 4 to the bridge deck construction position to vibrate the wet joints of the bridge deck. The vibration decompression machine chassis 4 has a cavity for the high-frequency vibrator 17 to move up and down. During vibration, the high-frequency vibrator 17 passes through the cavity to carry out construction work on the bridge deck.

[0029] Example 2, based on Example 1, includes a drivable chassis 1 as the walking mechanism and a fine-tuning hydraulic cylinder 2 as the hydraulic mechanism. The drivable chassis 1 is connected to the vibration damper chassis 4 via the fine-tuning hydraulic cylinder 2. The fine-tuning hydraulic cylinder 2 is used to fine-tune the walking distance, providing strong fault tolerance. A hydraulic pump station 9 is installed on the top of the drivable chassis 1, and the hydraulic pump station 9 is connected to the fine-tuning hydraulic cylinder 2 to provide it with energy.

[0030] For fine-tuning guidance, outer square tubes 3 are fixed to both sides of the rear of the drivable chassis 1, and inner square tubes 8 are fixed to both sides of the front of the vibration exhaust machine chassis 4. The inner square tubes 8 are fitted inside the outer square tubes 3. The outer square tubes 3 can be 60*60 mm in diameter, and the inner square tubes 8 can be 50*50 mm in diameter. When the fine-tuning hydraulic cylinder 2 finely adjusts the distance between the drivable chassis 1 and the vibration exhaust machine chassis 4, the inner square tubes 8 and outer square tubes 3 serve as guides.

[0031] As a preferred embodiment, a meter counter 7 is installed at the bottom of the drivable chassis 1. This high-precision meter counter accurately positions the distance of each vibration cycle. The meter counter 7 can arbitrarily set the distance of a single vibration cycle with accuracy down to the millimeter. An alarm sounds when the device travels beyond the set distance, featuring ease of operation and high precision. A transformer 13 is installed on the outside of the vibrator positioning plate 5, connected to the hydraulic pump station 9 to supply it with suitable voltage. A control box 19 is installed at the rear of the vibration de-vibration machine chassis 4. The vibration power can be flexibly set via a knob on the control box 19. Alternatively, the control box 19 can be configured as an intelligent box with wireless communication, equipped with a handheld remote control for convenient operation.

[0032] Example 3, based on Example 1, has a vibratory plate 12 installed at the front of the drivable chassis 1, and an attached vibrator 11 installed on the vibratory plate 12 for compacting concrete in bridge construction. Here, a thickened vibratory plate 12 and a high-frequency attached vibrator 11 are used to improve the leveling ability.

[0033] Please see Figure 3 The vibratory plate 12 is connected to the tread plate 20 via a lifting hydraulic cylinder 18. The attached vibrator 11 is installed on the top of the tread plate 20 and is lifted by the lifting hydraulic cylinder 18 to meet the requirements of different bridge deck heights. The lifting hydraulic cylinder 18 is powered by a hydraulic pump station 9.

[0035] In the scheme of embodiment 3, the walking mechanism first vibrates and flattens the wet joint of the bridge concrete deck by attaching vibrator 11 when walking, and then moves a distance to reach the vibration dissipation mechanism, and then the high-frequency vibrator 17 continues to vibrate and flatten the wet joint of the bridge deck.

[0036] Based on Examples 1-3, the following steps are performed in specific operations:

[0037] Drive or hoist this ride-on bridge deck wet joint vibrator to the work area, check that the battery power of the traveling mechanism is sufficient and that the external power supply connection of the vibrator is correct; select the appropriate vibrator positioning plate 5 according to the spacing of the reinforcing bars and install it; after the wet joint is poured, drive this equipment to the starting vibration position, and set the single travel distance of the meter 7 according to the vibration beat distance; start vibration, first press the remote control button to vibrate using the high-frequency vibrator 17, then immediately lower the remote control connecting flange 15, and after the vibration is in place, raise the remote control connecting flange 15; after the high-frequency vibrator 17 rises to leave the concrete surface, stop the remote control high-frequency vibrator 17.

[0038] Drive the equipment to the next vibration beat position. After reaching the set beat distance, the meter counter 7 alarms and stops moving. If slight adjustments are needed, use the fine-tuning hydraulic cylinder 2 to fine-tune. Repeat the remote control operation of the high-frequency vibrator 17 to vibrate and raise / lower. Drive the lifting hydraulic cylinder 18 to lower the platen 20 so that it is close to the wet joint concrete surface. Remotely turn on the attached vibrator 11 and repeat the moving and vibration dissipation remote control operation.

[0039] The purpose of this solution is to address the issue of vibration compaction during wet joint pouring in bridge decks by providing a mobile, ride-on vibratory compactor. This improves the efficiency of wet joint vibration operations, reduces labor intensity, enhances the stability of the vibration process, and increases the intelligence of the wet joint vibration operation. The lifting height of the high-frequency vibrator 17 can be adjusted according to the depth of the wet joint, and the vibrator positioning plate 5 can be replaced according to different rebar spacings. All high-frequency vibrators 17 and attached vibrators 11 are connected via quick couplings for easy maintenance.
