Abstract
Description
Technical Field
[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a rotation restriction structure for a vibratory impactor head. Background Technology
[0002] During construction, the vibratory compactor often experiences slow rotation of its guide rod and lifting head due to friction with the ground soil. Excessive rotation of the vibratory compactor casing is not permitted due to the cables and water / gas pipelines extending from the guide rod.
[0003] Commonly used anti-piracy methods:
[0004] 1. Tie a rope to the horizontal bar at the top of the guide rod and hold it with a person or a winch. The disadvantages are that it requires manpower, the strength cannot be accurately controlled, and it requires intermittent operation.
[0005] 2. Installing a rotary joint under the hoist head allows the cables and pipelines to pass through it for a transition. This way, when the guide rod rotates, the hoist head and cable pipelines will not rotate with it. The disadvantages are its complex structure, the risk of electro-hydraulic leakage, and high cost.
[0006] 3. After the equipment begins to rotate, the vibratory impactor is stopped first, and then switched to reverse start to make the equipment rotate back to its original position. The disadvantage of this method is that frequent start-stop operations waste working time and reduce construction efficiency. Utility Model Content
[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a rotation limiting structure for the vibratory impactor head, which can effectively limit the rotation of the guide rod and prevent large-scale rotation of the guide rod from damaging the internal cables and water pipes.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A vibratory impactor lifting head rotation limiting structure includes a vibratory impactor lifting rod and a take-up mechanism fixed to the ground. A fixed pulley is installed at the top of the vibratory impactor lifting rod. A horizontal bar is fixed to one side of the top of the vibratory impactor lifting rod. The horizontal bar is horizontally arranged and parallel to the axis of the take-up mechanism. A first rope is attached to the end of the horizontal bar. A docking lug is fixed above one side of the vibratory impactor lifting rod. A second rope is connected to the end of the docking lug. The second rope and the first rope are parallel to each other. The second rope and the first rope are wound around the take-up mechanism. A tension detection mechanism for measuring tension is also installed on the surface of the second rope. The tension data of the tension detection mechanism is wirelessly transmitted to the controller of the take-up mechanism.
[0010] Furthermore, the tension detection mechanism detects the tension of the second rope in real time. The preset tension of the tension detection mechanism is used to keep the second rope taut. When the tension of the tension detection mechanism is less than a threshold, the take-up mechanism is controlled to rotate to tighten the first and second ropes until the tension is restored. When the tension of the tension detection mechanism is greater than the threshold, the take-up mechanism is controlled to reverse to relax the first and second ropes until the tension is restored.
[0011] Furthermore, the winding mechanism is a winch, which includes a fixed plate fixed to the ground, a drum rotatably mounted on the inner side of the fixed plate, a motor fixed on the outer side of the fixed plate, the drum mounted on the output shaft of the motor, and a partition plate provided at the center of the surface of the drum, which divides the drum into two equal areas, and the second rope and the first rope are wound around different areas of the drum respectively.
[0012] Furthermore, the angle between the second rope and the first rope and the ground is an acute angle.
[0013] Furthermore, the tension detection mechanism is a tensioning wheel.
[0014] Furthermore, the tension detection mechanism is a force gauge.
[0015] Furthermore, the tension detection mechanism is a suspension angle control structure.
[0016] Furthermore, the tension detection mechanism is directly implemented through constant torque electrical control of the motor.
[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. By adding a second rope and a tension detection mechanism for automatic control of the rope length, the rope length can be automatically adjusted to follow the lifting and lowering of the hoist.
[0018] 2. Always maintain restrictions on the rotation of the lifting head, so that the lifting head can only rotate within a certain range, preventing damage to the internal cables due to excessive rotation, and eliminating the need for personnel to be on duty.
[0019] 3. It is simple to implement and low in cost, and all components are commonly used in engineering construction. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0028] refer to Figures 1-5 As shown, a vibratory impactor head rotation limiting structure includes a vibratory impactor rod 1 and a take-up mechanism 6 fixed to the ground. A fixed pulley 11 is installed on the top of the vibratory impactor rod 1. A crossbar 2 is fixed to one side of the top of the vibratory impactor rod 1. The crossbar 2 is horizontally set and always remains perpendicular to the vibratory impactor rod 1. The crossbar 2 is set parallel to the axis of the take-up mechanism 6 so that the first rope 3 and the second rope 4 are in a taut state. The first rope 3 is tied to the end of the crossbar 2. A connecting ear plate 12 is fixed above one side of the vibratory impactor rod 1. The end of the connecting ear plate 12 is connected to the second rope 4. The second rope 4 and the first rope 3 are set parallel to each other. The second rope 4 and the first rope 3 are wound around the take-up mechanism 6. The take-up mechanism 6 controls the first rope 3 and the second rope 4 synchronously. A tension detection mechanism 5 for measuring tension is also installed on the surface of the second rope 4. The tension data of the tension detection mechanism 5 is wirelessly transmitted to the controller of the take-up mechanism 6.
[0029] refer to Figure 1 and Figure 3 As shown, the tension detection mechanism 5 detects the tension of the second rope 4 in real time. The preset tension of the tension detection mechanism 5 is used to keep the second rope 4 taut. When the tension of the tension detection mechanism 5 is less than the threshold, the take-up mechanism 6 is controlled to rotate to tighten the first rope 3 and the second rope 4 until the tension is restored. When the tension of the tension detection mechanism 5 is greater than the threshold, the take-up mechanism 6 is controlled to reverse to relax the first rope 3 and the second rope 4 until the tension is restored. This achieves automatic adjustment of the rope so that the rope can adapt to the up and down movement of the vibratory boom 1 during operation and maintain the rope tension.
[0030] refer to Figure 4 As shown, the winding mechanism 6 is a winch. The winding mechanism 6 includes a fixed plate 61 fixed to the ground. A drum 63 is rotatably mounted on the inner side of the fixed plate 61. A motor 62 is fixed on the outer side of the fixed plate 61. The drum 63 is mounted on the output shaft of the motor 62. An isolation plate 64 is provided at the center of the surface of the drum 63. The isolation plate 64 divides the drum 63 into two equal areas. The second rope 4 and the first rope 3 are wound on different areas of the drum 63, so that the first rope 3 and the second rope 4 can be wound and unwound synchronously, realizing synchronous control.
[0031] The angle between the second rope 4 and the first rope 3 and the ground is an acute angle to ensure good operation.
[0032] refer to Figure 3 As shown, tension detection mechanism 5 is a tensioning wheel.
[0033] refer to Figure 3 As shown, tension detection mechanism 5 is a tension gauge.
[0034] refer to Figure 3 As shown, the tension detection mechanism 5 is a suspension angle control structure.
[0035] refer to Figure 3 As shown, the tension detection mechanism 5 is directly controlled by constant torque electric control of the motor.
[0036] The working principle of this utility model is as follows: During use, the predetermined value of the tension detection mechanism 5 ensures that the second rope 4 is always taut, and that the first rope 3 and the second rope 4 are always parallel to each other. The tension detection mechanism 5 detects the tension of the second rope 4 in real time and transmits the data to the controller of the motor 62. Since the second rope 4 and the first rope 3 are wound on the left and right sides of the drum 63 respectively, the first rope 3 and the second rope 4 can be wound and unwound synchronously. When the vibratory boom 1 is lowered, the second rope 4 is relaxed, and at this time the winding mechanism 6 tightens the first rope 3 and the second rope 4. Conversely, when the vibratory boom 1 is raised, the tension of the tension detection mechanism 5 increases, and the winding mechanism 6 releases a portion of the first rope 3 and the second rope 4 until the tension of the tension detection mechanism 5 returns to the threshold value.
[0037] When the vibratory boom 1 rotates, if the rotation range causes the crossbar 2 to be within half a circumference facing the drum, and if the rotation range causes the crossbar 2 to be within half a circumference facing the drum 63, the end rotates towards the take-up mechanism 6. At this time, the first rope 3 is loosened, and the vibratory boom 1 can rotate freely without being restricted by the first rope 3. When the rotation range causes the crossbar 2 to be within half a circumference facing away from the drum 63, that is, rotating away from the take-up mechanism 6, the first rope 3 cannot extend, thus restricting the crossbar from continuing to rotate outward, thereby achieving the function of restricting the rotation of the boom.
[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
