DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0035] Reference Figures 1-4 The specific embodiments of the present application provide a novel high-efficiency dynamic compactor, which comprises a vehicle body 1, an arm support 4 and a winch 2 installed on the vehicle body 1, and further comprises:

[0036] A ring baffle 9 is fixedly connected to the side of the capstan 8 of the winch 2, and two groups of steel wire ropes 3 are wound on the capstan 8 and located on the two sides of the ring baffle 9.

[0037] A fixed pulley set is installed on the top of the arm support 4, and the two ends of the two groups of steel wire ropes 3 are wound through the fixed pulley set.

[0038] A movable pulley set, the two groups of steel wire ropes 3 are sequentially wound through the two groups of fixed pulley sets and the movable pulley set, and are hingedly connected to the arm support 4.

[0039] The lifting speed of the rammer of the existing strong ramming machine depends on the power of the winch and the ratio of the wire rope pulley set. Taking the construction of 18000 kn*m ramming energy with the lifting of a 90-ton rammer to a height of 20 m as an example, under the condition that the power of the wire rope winch is constant, the wire rope pulley set needs to be based on 8 times the ratio for the lifting operation of the rammer, which is low in operation efficiency and low in daily output. In the present application, a ring-shaped baffle 9 is added in the winch 2. By arranging the ring-shaped baffle 9, two steel wires 3 can be wound on both sides of the ring-shaped baffle 9, and the original winding of one steel wire 3 on the winch 8 is changed to winding of two steel wires, one on each side of the ring-shaped baffle 9. Two groups of steel wires 3 pass through the fixed pulley set and the movable pulley set respectively, and the lifting speed of the rammer 7 is doubled, the construction efficiency is doubled, and the daily output is doubled, which greatly improves the construction efficiency.

[0040] When the ring-shaped baffle 9 is arranged as a group, the effect of changing the original winding of one steel wire 3 on the winch 8 to winding of two steel wires is achieved without a significant increase in the amount of steel wire 3 used compared to the original, and the effect of one steel wire on each side of the ring-shaped baffle 9 is achieved.

[0041] Further optimization scheme, the movable pulley set includes:

[0042] The hanging block 6, the rammer 7 is installed below the hanging block 6;

[0043] The movable pulley 12, a plurality of movable pulleys 12 are rotatably connected in the hanging block 6, and the hinged ends 11 of the two groups of steel wires 3 pass through the plurality of movable pulleys 12 respectively.

[0044] Further optimization scheme, the movable pulley 12 is arranged in four groups, and the hinged end 11 of a group of steel wires 3 passes through two groups of movable pulleys 12.

[0045] Further optimization scheme, the fixed pulley set includes:

[0046] The fixed pulley 5, a plurality of fixed pulleys 5 are rotatably connected at the top end of the arm frame 4, and the hinged ends 11 of the two groups of steel wires 3 pass through the plurality of fixed pulleys 5 respectively.

[0047] The hinged end 11 of a group of steel wires 3 corresponds to winding of two groups of fixed pulleys 5, i.e. the two groups of steel wires 3 correspond to four groups of fixed pulleys 5.

[0048] Further optimization scheme, further includes:

[0049] The guide pulley 13, the guide pulley 13 is rotatably connected at the top end of the arm frame 4, and the hinged end 11 of a group of steel wires 3 passes through a group of guide pulleys 13, two groups of fixed pulleys 5 and two groups of movable pulleys 12 in sequence.

[0050] The guide pulley 13 helps to stabilize the steel wire 3 during use.

[0051] In this way, the single steel wire rope 3 is wound into two sets of fixed pulleys 5 and two sets of movable pulleys 12, which is 4 times the ratio. Since the lifting speed of the two steel wire ropes 3 wound on the winch 2 is the same, and the rope length is also the same, the deviation of the tension borne by the two steel wire ropes 3 can be avoided. In this way, the ram lifting speed is doubled, the construction efficiency is doubled, the daily output is doubled, and the construction efficiency is greatly improved. In the original equipment working principle, the construction operation using one steel wire rope 3 wound in the movable pulley set at 8 times the ratio is changed to using two steel wire ropes 3, and the single steel wire rope 3 is wound into two sets of fixed pulleys 5 and two sets of movable pulleys 12 to perform 4 times winding operation. Since the ratio is halved, the overall steel wire rope 3 usage does not increase significantly (the original length of one can be cut into two or two new steel wire ropes 3 are used), but the lifting speed is doubled, which directly leads to a doubling of daily output and a significant increase in efficiency.

[0052] Further optimization scheme also includes:

[0053] The fixed block 10 is fixedly connected to the lower jaw of the top end of the arm support 4, and the hinged ends 11 of the two steel wire ropes 3 are hinged to the fixed block 10.

[0054] The main function of the fixed block 10 is to connect the hinged ends 11 of the two steel wire ropes 3. Originally, one steel wire rope 3 was connected to one fixed block 10, and the hinged ends 11 of the two steel wire ropes 3 were connected to the two fixed blocks 10.

[0055] Further optimization scheme also includes:

[0056] The fixed slot (not labeled in the figure) is provided on the winch 8 and located on both sides of the annular baffle 9, and the winding end of the steel wire rope 3 is clamped in the fixed slot.

[0057] Through the fixed slot, the winch 2 can simultaneously wind two steel wire ropes 3.

[0058] Further optimization scheme, the arm support 4 is a box-shaped structure or a truss structure.

[0059] In this way, the stability and safety of the overall structure can be ensured.

[0060] Further optimization scheme, the bottom of the arm support 4 is hinged to the vehicle body 1, and the arm support 4 adjusts the angle through the traction part.

[0061] The traction part can be another winch, which pulls the arm support 4 through the steel wire rope, so that the arm support 4 rotates around the hinge point by a certain angle.

[0062] The present application, in actual use, can result in a need for a larger horsepower engine to provide more power to increase the torque of the hoist 2 responsible for lifting the rammer 7 due to the increased construction efficiency.
