[0001] The utility model relates to the technical field of building bridge construction, in particular to a lifting device of a vibrating system used for concrete pouring. Background Art
[0002] At present, my country's highway, railway and municipal construction are developing rapidly, and most of the construction projects involve bridge construction. An important part of bridge construction is the pouring of cement piers.
[0003] The concrete pouring process is generally divided into pre-pouring inspection, pump truck entry and concrete transportation, concrete slump inspection, concrete pouring and vibration, and concrete curing.
[0004] Among them, the most important process is concrete pouring and vibration. When pouring cement piers, they must be vibrated and compacted, and bubbles should be strictly avoided inside and outside the piers, otherwise it will seriously affect the bearing capacity of the piers.
[0005] At present, the pouring of cement piers mainly relies on manual labor with hand-held vibrators entering the formwork several meters or even dozens of meters deep for vibration. The above situation has unavoidable problems such as high labor intensity for workers, high temperature inside the formwork in summer, and the risk of falling objects from high altitude.
[0006] In recent years, some concrete pouring vibration equipment has been gradually developed, which has achieved the mechanization of vibration operation to a certain extent, and can significantly improve the labor intensity and working environment of vibration operation, but the existing technology still has the following shortcomings:
[0007] 1. The existing vibrating equipment has a low degree of integration, or even no integration, for example, there is no integrated cement pouring barrel device.
[0008] 2. Due to the limited internal space of the steel cage during pouring, the telescopic stroke of the telescopic rod that drives the vibrating rod of the vibration equipment to move horizontally will be affected. Therefore, in actual use, the vibrating equipment in the prior art cannot vibrate the center of the pier column, resulting in uneven vibration.
[0009] 3. The vibrating rod of the vibrating equipment in the prior art has no vertical displacement movement function when working, and cannot achieve fast insertion and slow lifting. It can only be fixed and vibrated, which does not meet the requirements of fast insertion and slow lifting mentioned in GB50666-2011 "Concrete Structure Engineering Construction Code".
[0010] 4. The vibrating equipment in the prior art is not equipped with a concrete diversion device, and when the working height is high, concrete segregation may occur.

[0043] An embodiment of a vibrating system for concrete pouring of the utility model is further described with reference to the accompanying drawings.
[0044] like Figures 1 to 19 As shown, a vibrating system for concrete pouring includes a lifting device 1, a string tube group 2, a bearing device 3, a rotating device 4, a horizontal telescopic device 5, and a vibrating device 6;
[0045] The lifting device 1 is connected to the carrying device 3 by wire rope hoisting; the lifting device 1, the carrying device 3, the rotating device 4, and the horizontal telescopic device 5 are all provided with passage openings for the passage of concrete slurry; the upper port of the string tube group is connected to the passage opening of the lifting device 1, and the lower port of the string tube group is connected to the passage opening of the carrying device 3; the passage opening of the carrying device 3 is also connected to the passage opening of the rotating device 4, and the passage opening of the rotating device 4 is connected to the passage opening of the horizontal telescopic device 5; the string tube group is connected to the passage openings of the lifting device 1, the carrying device 3, the rotating device 4, and the horizontal telescopic device 5 to form a passage for concrete slurry;
[0046] The lifting device 1 can drive the carrying device 3, the rotating device 4, the horizontal telescopic device 5, and the vibrating device 6 to perform up and down lifting movements; the rotating device 4 can drive the horizontal telescopic device 5 and the vibrating device 6 to perform rotational movements; the horizontal telescopic device 5 can drive the vibrating device 6 to perform horizontal movements; and the vibrating device 6 can perform vibration operations on the concrete slurry.
[0047] The lifting device 1 includes an electric winch 1.1, a box-shaped mounting bracket 1.2, and a pulley system; the electric winch 1.1 is installed on the mounting bracket 1.2, and the drum of the electric winch 1.1 is divided into more than three grids, and each grid of the drum of the electric winch 1.1 is wound with an independent steel wire rope 1.3; the pulley system is installed on the mounting bracket 1.2, and the pulley system includes a plurality of horizontal guide pulleys and a plurality of vertical guide pulleys, and the vertical guide pulleys are evenly distributed about the passage opening of the lifting device 1; the steel wire ropes 1.3 on the drum of the electric winch 1.1 are connected to the bearing device 3 after being vertically changed one by one through the vertical guide pulleys; when the steel wire ropes 1.3 on the drum of the electric winch 1.1 pass through the vertical guide pulleys one by one, if it is necessary to change direction randomly in the horizontal direction, the horizontal change is made through the horizontal guide pulley. The lifting device 1 further comprises an adjusting electric cylinder 1.6, which is located on the vertical section of the steel wire rope 1.3 of the electric winch 1.1.
[0048] Specifically, in this example, the electric winch 1.1 of the lifting device 1 is mounted on a box-shaped mounting bracket 1.2, and the drum of the electric winch 1.1 is divided into three compartments. One electric winch 1.1 can simultaneously retract and release three steel wire ropes 1.3. One end of the three steel wire ropes 1.3 is fixed on the drum of the electric winch 1.1, passes through the pulley system, and the other end is fixed on the carrying device 3, wherein the vertical section of the steel wire rope 1.3 is equipped with an adjusting electric cylinder 1.6. Three (six) pulleys are installed on the box-shaped mounting bracket 1.2. Three steel wire ropes 1.3 first pass through two three-grid pulleys 1.4.1, and then one of the steel wire ropes 1.3 passes downward through the through hole and is connected to one of the adjusting electric cylinders 1.6; the other two steel wire ropes 1.3 continue to pass through two two-grid pulleys 1.4.2, and then one of the steel wire ropes 1.3 passes downward through the through hole and is connected to one of the adjusting electric cylinders 1.6; the last steel wire rope 1.3 continues to pass through two one-grid pulleys 1.4.1 and then passes downward through the through hole and is connected to the adjusting electric cylinder 1.6. The adjusting electric cylinder 1.6 has a mounting hole at each end, one end is connected to the steel wire rope 1.3, and the other end is connected to the lifting lug of the load-bearing device 3 and bears the weight. In order to avoid the situation that when one electric winch 1.1 drives three steel ropes 1.3, the positions of the steel ropes 1.3 and the edge of the drum are different, which causes the three steel ropes 1.3 to have different strokes, a synchronous swinging synchronous wire arrangement device 1.7 is specially provided. The synchronous wire arrangement device 1.7 is provided with three rope grooves. The width of the three rope grooves is matched with the thickness of the steel ropes 1.3. The three rope grooves are used to limit the three steel ropes 1.3, so as to ensure that the arrangement spacing of the three steel ropes on the drum is consistent, so as to achieve the effect of arranging the steel ropes 1.3 on the drum in a relatively neat manner. The synchronous wire arrangement device 1.7 can be hoisted on the box-shaped mounting bracket 1.2 so that it can swing with the three steel ropes 1.3. It can also be slidably installed on the box-shaped mounting bracket 1.2 so that it can slide in a direction parallel to the axis of the drum. After the rope arrangement effect of the synchronous wire arrangement device 1.7, if there is still a slight asynchronism among the three steel ropes 1.3, the weight at the lower end can be leveled by adjusting the electric cylinder 1.6. The box-shaped mounting bracket 1.2 can be fixed in the middle of the steel tube beam 1.5, and both ends of the steel tube beam 1.5 can be placed on the steel cage of the pier to be cast respectively to play a load-bearing role.
