Description

Technical Field

[0003] The above-mentioned project rationally and effectively applied the dynamic compaction construction technology, which greatly shortened the construction period, saved the project investment, and achieved good economic and social benefits. In construction projects, in order to ensure the quality of the building, the loose soil is usually compacted by a dynamic compaction machine. The dynamic compaction machine is a soft foundation treatment equipment. When working, it lifts the heavy object to a certain height, so that the heavy object has a certain potential energy, and then separates the heavy object from the dynamic compaction machine through the unhooking device. The heavy object falls freely with the acceleration of free fall, and then hits the foundation, thereby achieving the purpose of compacting the foundation.

[0004] However, in actual practical use, the unhooking device in the prior art has no protection mechanism, which leads to poor safety of the unhooking device. It does not unhook when it should, causing the ramming unit to tilt upward; it unhooks when it should not, causing the crane arm to tilt backward, which can easily cause a "back-of-the-bar" accident.

[0023] The utility model will be further described below in conjunction with the accompanying drawings.

[0024] See also Figure 1-5 The utility model is a decoupling device for a tamping machine, comprising a tamping plate 1, a fixed cylinder 2 is arranged on the outside of the tamping plate 1, a decoupling structure 3 is arranged on the outside of the fixed cylinder 2, an electromagnetic cylinder 4 is connected to the upper side of the fixed cylinder 2, the electromagnetic cylinder 4 is connected to the fixed cylinder 2, a hanging ring 5 is connected to the upper surface of the electromagnetic cylinder 4, a driving structure 6 is arranged on the upper surface of the fixed cylinder 2, a suction plate 101 is connected to the upper surface of the tamping plate 1, wherein the preferred choice is that the material of the suction plate 101 is cast iron, so that the suction plate 101 is attracted by the electromagnetic cylinder 4 through magnetic force in the later stage, and the outer surface of the tamping plate 1 Two fixing grooves 102 are provided, among which the preferred choice is that the cross-sectional shape of the fixing groove 102 is in the shape of "7". Of course, the shape of the limiting plate 304 matches the shape of the fixing groove 102, so that it is convenient for the limiting plate 304 to enter the fixing groove 102 in the later stage, thereby fixing the ramming plate 1 in the fixing tube 2 to insure the ramming plate 1 and avoid the suction plate 101 being unable to be attracted by the magnetic force of the electromagnetic tube 4 due to accidents. Two groups of through grooves 201 are provided on the outer surface of the fixing tube 2, and each group of through grooves 201 corresponds to their own fixing grooves 102.

[0025] The unhooking structure 3 includes a disengagement plate 301, a movable shaft 302, a spring 303, a limit plate 304 and a movable seat 202. The upper surface of the fixed cylinder 2 is connected to two movable seats 202, and the two movable seats 202 are respectively located on the left and right sides of the electromagnetic cylinder 4. Each movable seat 202 is movably connected to two movable shafts 302. The end faces of the two movable shafts 302 are connected to a disengagement plate 301. The two disengagement plates 301 are respectively located on the front and back sides of the electromagnetic cylinder 4. The surface of each disengagement plate 301 is connected to two limit plates 304, and each group of through grooves 201 corresponds to its own limit plate 304.

[0026] The movable shaft 302 is in a T-shape, and a spring 303 is sleeved on the surface of the movable shaft 302. One end of the spring 303 abuts against the end surface of the movable shaft 302, and the other end of the spring 303 abuts against the surface of the movable seat 202. The spring 303 ensures that the two limit plates 304 on the two separation plates 301 are both located in their respective fixed grooves 102.

[0027] The driving structure 6 includes an electric push rod 601, a driving rack 602, a driving gear 603 and a driven rack 604. The upper surface of the fixed cylinder 2 is connected to the electric push rod 601. The telescopic rod of the electric push rod 601 is connected to one end of the driving rack 602. The driving rack 602 and the driven rack 604 are both movably connected to the outer surface of the fixed cylinder 2. The driving rack 602 and the driven rack 604 are respectively located on the left and right sides of the electromagnetic cylinder 4. The outside of the electromagnetic cylinder 4 is movably connected to the driving gear 603, and the driving gear 603 simultaneously engages the driving rack 602 and the driven rack 604.

[0028] Of course, a better choice is that the lower end of the fixed tube 2 is trumpet-shaped, which is convenient for the ramming plate 1 to enter the fixed tube 2. It is worth noting that the center of gravity of the ramming plate 1 is located at the bottom, and a more stable shape can be adopted, not necessarily the shape in the attached figure, to ensure that the ramming plate 1 always remains upright during the falling process, avoiding the situation where the ramming is not firm and the suction plate 101 cannot enter the electromagnetic tube 4 at a later time.

[0029] Working principle:

[0030] First, it is assumed that both the two disengagement plates 301 are disengaged from their respective through slots 201, and the hook of the crane is hung on the hanging ring 5, so as to connect the crane and the fixed cylinder 2. When connection is required, the fixed cylinder 2 is directly moved above the ramming plate 1, and the fixed cylinder 2 is lowered. At this time, the suction plate 101 enters the electromagnetic cylinder 4, and the electromagnetic cylinder 4 is turned on. The electromagnetic cylinder 4 generates a magnetic force to attract the suction plate 101. In order to avoid accidents that cause the electromagnetic cylinder 4 to generate insufficient magnetic force to attract the suction plate 101, the electric push rod 601 is started at this time, and the electric push rod 601 drives the drive The moving rack 602 moves on the upper surface of the fixed cylinder 2, and the driving rack 602 drives the driving gear 603 to rotate on the surface of the electromagnetic cylinder 4, and then the driving gear 603 drives the driven rack 604 to move on the upper surface of the fixed cylinder 2. At this time, the end faces of the driving rack 602 and the driven rack 604 do not abut on the two detachment plates 301 to which they belong. Under the action of the spring 303, the two limit plates 304 on each detachment plate 301 enter their respective fixed grooves 102, thereby completing the fixing of the detachment plate 301 to the ramming plate 1;

[0031] When it is necessary to disengage, start the electric push rod 601, which drives the driving rack 602 to move on the upper surface of the fixed cylinder 2, and the driving rack 602 drives the driving gear 603 to rotate on the surface of the electromagnetic cylinder 4, and then the driving gear 603 drives the driven rack 604 to move on the upper surface of the fixed cylinder 2. At this time, the end faces of the driving rack 602 and the driven rack 604 are both against the two disengagement plates 301 to which they belong, and the spring 303 is compressed. The two limit plates 304 on each disengagement plate 301 are disengaged from their respective fixed grooves 102. At this time, the magnetic force of the electromagnetic cylinder 4 is disconnected, and the disengagement of the ramming plate 1 can be completed.
