Description

Technical Field

[0001] The utility model relates to the technical field of concrete vibrating devices, and more particularly to a concrete vibrating device. Background Art

[0002] In the field of modern building construction, the quality of concrete is directly related to the strength and durability of the entire building structure. In order to improve the construction quality of concrete, the vibration process has become a vital link. The main purpose of vibration is to expel bubbles in the concrete and make the concrete more dense, thereby eliminating possible quality defects such as honeycomb surface, and ultimately improving the overall strength of the concrete floor or cushion. The traditional vibration method usually uses a single vibrating rod vibrating device. In this method, the construction workers need to insert the vibrating rods into the concrete one by one before the concrete is initially solidified, and vibrate the area around the vibrating rod. However, This traditional method has several obvious drawbacks: First, a single vibrator can only cover a small area around it at a time, which requires the operator to frequently move the vibrator to ensure that the entire concrete surface is fully vibrated. Second, due to the need to frequently move the vibrator, it is easy for some areas to be under-vibrated (missing vibration) or over-vibrated (false vibration). This uneven vibration will lead to inconsistent concrete quality and affect the strength and durability of the overall structure. In addition, the use of a single vibrator is time-consuming and labor-intensive, and the efficiency of this method is particularly low, especially in large-scale concrete pouring projects.

[0003] In order to solve the above problems, some improved concrete vibrating devices have adopted a design of multiple vibrating rods. This design has indeed improved the efficiency and coverage of vibration to a certain extent. However, this improved device also brings new challenges, mainly reflected in the handle design. First, most devices use fixed handles, but due to the different heights of operators, fixed-height handles are difficult to meet the needs of everyone, which not only affects the comfort of operation, but may also cause fatigue after long-term use, and even cause occupational health problems. Secondly, some devices use detachable handles to solve the height adaptation problem, but these designs often have the problem of cumbersome installation and disassembly processes. In actual construction environments, cumbersome adjustment operations may significantly reduce work efficiency.

[0004] In addition, although some devices attempt to adopt quick installation and disassembly mechanisms, these designs are often simple in structure and lack sufficient stability. In a high-frequency vibration working environment, this simple quick-change mechanism may cause the grip to loosen or even fall off accidentally during operation, posing a safety hazard to the operator.

At this time, the outer side of the insertion rod 20 loses the limit of the limiting sleeve 11, and then the rotating sleeve 8 is rotated. The rotating sleeve 8 will drive the insertion rod 20 to move, and then the side wall of the slot 22 will squeeze the end of the insertion rod 20. 22, one end of the rod 20 will be disengaged from the slot 22, and the other end of the rod 20 will drive the conical spring 21 to stretch, and at the same time the rotating sleeve 8 will drive the matching slot 6 to rotate. Due to the special structural design of the matching slot 6, when the matching slot 6 moves, the matching block 7 will drive the quick-change block 29 to disengage from the quick-change slot 28, and at the same time the quick-change block 29 will squeeze the push spring 30 connected on one side. When the rotating sleeve 8 cannot rotate, the quick-change block 29 will completely disengage from the quick-change slot 28. At this time, the reset spring 26 will push the reset plate 27 to reset, and then the reset plate 27 will push the quick-change rod 9 to separate from the quick-change sleeve 10, and then the quick-change rod 9 and the quick-change sleeve 10 will be pulled to both sides respectively, and the quick-change sleeve 10 and the quick-change rod 9 can be completely Remove it, thereby removing the handle 5, and then pass the quick-change rod 9 connected to one end of the replaced handle 5 through the corresponding mounting hole, and then fit the quick-change sleeve 10 to the outside of the quick-change rod 9 from the other side, and then one end of the quick-change rod 9 will push the reset plate 27, and then the reset plate 27 will squeeze the reset spring 26.

The output end of the motor 36 drives the transmission wheel 38 set at the output end of the reducer 37 to rotate after the deceleration effect of the reducer 37. Then the transmission wheel 38 set at the output end of the reducer 37 will drive one end of the lead screw 35 installed on the transmission wheel 38 to rotate through the transmission belt 39 sleeved on the outside, and then the corresponding transmission wheel 38 will drive the lead screw 35 to rotate. Since the lifting plate 2 is rotatably connected to the lead screw 35 through a thread, the lifting plate 2 will drive the vibrating rod 3 and the vibrator 4 to slide along the slider 32 and the slide groove 33, so that multiple vibrating rods 3 are inserted into the concrete at the same time to vibrate the concrete, realizing synchronous vibration of a large area of ​​concrete, and then the entire device can be pushed to move by the handle 5 to realize vibration of concrete in other areas.

At this time, the outer side of the insertion rod 20 loses the limit of the limiting sleeve 11, and then the rotating sleeve 8 is rotated. The rotating sleeve 8 will drive the insertion rod 20 to move, and then the side wall of the slot 22 will squeeze the end of the insertion rod 20.

Due to the special structural design of the matching slot 6, when the matching slot 6 moves, the matching block 7 will drive the quick-change block 29 to disengage from the quick-change slot 28, and at the same time the quick-change block 29 will squeeze the push spring 30 connected on one side. When the rotating sleeve 8 cannot rotate, the quick-change block 29 is completely disengaged from the quick-change slot 28. At this time, the reset spring 26 will push the reset plate 27 to reset, and then the reset plate 27 will push the quick-change rod 9 to separate from the quick-change sleeve 10, and then the quick-change rod 9 and the quick-change sleeve 10 are pulled to both sides respectively, and the quick-change sleeve 10 and the quick-change rod can be separated. 9 is completely removed, thereby removing the handle 5, and then the quick-change rod 9 connected to one end of the replaced handle 5 is passed through the corresponding mounting hole, and then the quick-change sleeve 10 is fitted to the outside of the quick-change rod 9 from the other side, and then one end of the quick-change rod 9 will push the reset plate 27, and then the reset plate 27 will squeeze the reset spring 26. When the reset spring 26 is squeezed to the limit, the rotating sleeve 8 is rotated in the opposite direction, and the rotating sleeve 8 will drive the matching groove 6 to reset, and then the matching groove 6 and the matching block 7 cooperate, as well as the reset effect of the push spring 30, so that the quick-change block 29 is engaged with the quick-change groove 28.
