Description

Technical Field

[0001] This utility model belongs to the field of precast concrete vibration technology, and in particular relates to a mobile precast concrete vibration device. Background Technology

[0002] Precast concrete structures are a method of fabricating precast concrete structures used in water conservancy engineering construction to improve construction efficiency. Specifically, compared with on-site construction methods, precast concrete structures not only allow for prefabrication but also facilitate construction and installation, thus significantly improving construction efficiency.

[0003] In the process of precast concrete structure pouring, in order to achieve concrete compaction, existing technology uses concrete vibrators to achieve compaction during the pouring of concrete into the reinforcing cage structure. The main structure of the concrete vibrator includes a vibrating rod and a rubber tube installed on the vibrating rod. During construction, the vibrating rod compacts the concrete.

[0004] However, in actual work, due to the dimensional requirements of precast structures, manual labor is needed to insert vibrators one by one into the rebar cage through the openings, compacting the concrete inside. Clearly, this method is more flexible and easier to operate for smaller precast structures. However, for larger precast structures, due to the greater number of parts requiring vibration, multiple operators are needed to insert vibrators one by one through the openings of the rebar cage. This method not only requires excessive labor but also involves a very large overall workload.

[0005] In order to improve the vibration effect, vibrators often need to be placed in the steel cage at intervals. If the number of workers is reduced during the repeated raising and lowering of the vibrators, the workload and efficiency will be very low. However, the increase in the number of construction workers will inevitably lead to an increase in labor costs. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a mobile precast concrete vibration device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mobile precast concrete vibration device includes a mobile vibration mechanism, wherein the mobile vibration mechanism includes a vibrator mounting frame and a plurality of position-adjustable vibration structures are installed inside the vibrator mounting frame.

[0009] The vibration structure includes a rolling frame that rolls within a vibrator mounting frame, on which a vibrator is mounted.

[0010] The bottom of the rolling frame suspends the vibrator via a suspension structure;

[0011] The top of the vibrator mounting frame is equipped with an upper cover, and the upper cover has a long rectangular sliding opening. Several locking structures are fixedly connected to the top of the rolling frame. The vibrator is positioned after adjustment through the locking structures.

[0012] Preferably, a rectangular opening is provided at the center of the vibrator mounting bracket;

[0013] The rectangular opening has inner track slots on its left and right side walls, and the rolling frame is equipped with several rollers that roll within the inner track slots.

[0014] Preferably, the transverse cross-sectional shape of the rolling frame is I-shaped, and two rollers are respectively installed at the left and right ends of the rolling frame, one in front and one behind.

[0015] The center of the rolling frame has a through-hole, and the rubber hose on the vibrator passes through the through-hole upwards. The rubber hose on the vibrator passes through the rectangular opening.

[0016] Preferably, the bottom of the vibrator mounting bracket is equipped with a bottom cover;

[0017] The bottom cover has a lower rectangular sliding opening, through which the vibrating rod of the vibrator passes.

[0018] Preferably, a pair of locking structures spaced apart front to back are installed on the top of the rolling frame.

[0019] Preferably, the locking structure includes a locking screw fixedly connected to the rolling frame, the locking screw passing through the long rectangular slide opening;

[0020] The locking screw is threaded with a nut positioned on the top cover.

[0021] Preferably, the suspension structure includes a clamp structure installed at the lower end of the rubber tube on the vibrator;

[0022] Suspension ropes are fixedly connected to both sides of the clamp structure, and the suspension ropes are fixed to the bottom of the rolling frame.

[0023] Preferably, the clamp structure includes a pair of arc-shaped clamp rods that are fitted and clamped onto the rubber tube, and the two ends of the arc-shaped clamp rods are fastened by bolts respectively;

[0024] A protrusion is fixedly connected to the outer wall of the arc-shaped clamp rod, and a suspension rope is fixedly connected to the protrusion.

[0025] Preferably, handrails are fixedly connected to the front and rear side walls of the vibrator mounting frame.

[0026] This utility model has the following beneficial effects:

[0027] 1. During construction, the position of the vibrator can be adjusted flexibly according to the opening of the reinforcing cage. The adjustment is achieved through a rolling mechanism, overcoming the difficulty of adjusting heavier vibrators. Furthermore, the rolling mechanism minimizes resistance when concrete adheres to the vibrator, increasing its weight. During construction, the spacing of the vibrators can be adjusted according to the cage opening position, allowing multiple vibrators to be lowered simultaneously for compaction at multiple locations, significantly improving construction efficiency.

[0028] 2. During the operation, the locking screw moves horizontally in the long rectangular slide during the rolling adjustment process. After the position is adjusted, the nut is lowered until it is pressed against the long rectangular slide, thus positioning the vibrator. Specifically, when the nut is pressed against the edge of the long rectangular slide, frictional resistance is formed between the nut and the top cover, thereby making it difficult for the vibrator to move through frictional resistance.

[0039] Example 1

[0040] like Figure 1-5 As shown, a mobile precast concrete vibrating device includes a mobile vibrating mechanism, which includes a vibrator mounting frame 11. The vibrator mounting frame 11 has a rectangular cross-sectional shape and a rectangular opening of a certain length in the center as an adjustment port for the vibrator.

[0041] Specifically, the vibrator mounting bracket 11 has several adjustable vibrating structures installed inside.

[0042] Specifically, the vibration structure includes a rolling frame 31 that rolls within the vibrator mounting bracket 11, on which a vibrator 2 is mounted. The rolling frame 31 has an I-shaped cross-section, and two rollers 32 are mounted at its left and right ends, respectively. A through-hole is located at the center of the rolling frame 31, through which the rubber hose of the vibrator 2 passes upwards, and through a rectangular opening.

[0043] Correspondingly, inner track slots A are respectively opened on the left and right side walls of the rectangular opening, and several rollers 32 are installed on the rolling frame 31, and the rollers 32 roll in the inner track slots A.

[0044] The above structure allows for highly flexible adjustment of the vibrator 2 position based on the opening of the reinforcing cage. During adjustment, the roller 32 is used for rolling adjustment, which solves the problem of difficulty in adjusting the heavy vibrator 2. Furthermore, if the weight of concrete adhering to the vibrator 2 increases, the rolling adjustment by the roller 32 reduces resistance.

[0045] During construction, the spacing of the vibrators 2 can be adjusted according to the position of the cage opening of the steel cage, so that multiple vibrators 2 can be lowered simultaneously during the vibration process, achieving vibration at multiple positions at one time, which greatly improves construction efficiency.

[0046] In actual work, the structure of the reinforcing cage is often a regular geometric structure (precast concrete structures are often regular in shape, and the shape of the reinforcing cage corresponds to the shape of the structure). Therefore, the positions of the cage openings on the tied reinforcing cage are mostly regularly spaced. This method often results in fewer adjustments during construction, thus improving the convenience of construction. Furthermore, due to the low adjustment resistance, the vibrator can be easily and quickly adjusted during construction.

[0047] Among them, the vibrator 2 is a conventional concrete vibrating device disclosed in the prior art, and its main structure includes a vibrating rod part 21 and a rubber tube 22 installed at the top of the vibrating rod part 21.

[0048] Example 2

[0049] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, in order to fix the vibrator after adjustment and increase the stability of construction, the top of the vibrator mounting frame 11 is equipped with an upper cover 12. The upper cover 12 has a long rectangular sliding opening 121. The top of the rolling frame 31 is fixedly connected with several locking structures. Through the locking structures, the vibrator 2 is positioned after adjustment.

[0050] Specifically, a pair of locking structures spaced apart front to back are installed on the top of the rolling frame 31. The locking structure includes a locking screw 33 fixedly connected to the rolling frame 31, the locking screw 33 passing through the long rectangular slide 121; a nut 331 positioned on the upper top cover 12 is threaded onto the locking screw 33.

[0051] During operation, during the rolling adjustment process, the locking screw 33 moves horizontally in the long rectangular slide 121. After the position is adjusted, the nut 331 is lowered and pressed against the long rectangular slide 121 to achieve the positioning of the vibrator 2. Specifically, when the nut 331 is pressed against the edge of the long rectangular slide 121, frictional resistance is formed between the nut 331 and the upper cover 12, thereby making it difficult for the vibrator 2 to move through frictional resistance.

[0052] Example 3

[0053] like Figure 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, the bottom of the rolling frame 31 suspends the vibrator 2 via a suspension structure. Specifically, the suspension structure includes a clamp structure 41 installed at the lower end of the rubber tube 22 on the vibrator 2. Suspension ropes 42 are fixedly connected to both sides of the clamp structure 41, and the suspension ropes 42 are fixed to the bottom of the rolling frame 31. The clamp structure 41 is a conventional clamp disclosed in the prior art. Specifically, the clamp structure 41 includes a pair of arc-shaped clamp rods that cooperate to clamp the rubber tube 22, and the two ends of the arc-shaped clamp rods are fastened by bolts.

[0054] The vibrator 2 of a certain weight is positioned by using a clamp in conjunction with the nut 331.

[0055] The bottom of the vibrator mounting bracket 11 is equipped with a bottom cover; the bottom cover has a lower rectangular sliding opening (not shown in the figure), the vibrator rod on the vibrator 2 passes through the lower rectangular sliding opening (not shown in the figure), and at the same time, the rubber tube 22 on the vibrator rod passes through the lower rectangular sliding opening (not shown in the figure) for a distance.

[0056] A boss 411 is fixedly connected to the outer wall of the aforementioned arc-shaped clamp rod, and a suspension rope 42 is fixedly connected to the boss 411.

[0057] Handrails 111 are fixedly connected to the front and rear side walls of the vibrator mounting frame 11. During construction, the handrails 111 facilitate the operator in lifting and placing the entire device.

[0058] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
