Description

Technical Field

[0001] This utility model relates to a vibrator, specifically a back-cover type vibrator suitable for clamping, positioning, and high-frequency sinking and pulling operations of concrete pipe piles, steel piles, etc., and particularly suitable for pulling out guardrail posts. It belongs to the technical field of pile foundation construction equipment. Background Technology

[0002] In the construction of road guardrails, bridge foundations and temporary supports, it is often necessary to drive or extract piles.

[0003] The existing hydraulic clamp-type vibrator technology has the following main problems in practical applications: 1) Uneven distribution of clamping force: Some pile clamping mechanisms are driven on one side or have an asymmetrical structure, which leads to uneven distribution of clamping force on both sides of the pile body, which can easily cause eccentric loading, affecting the sinking and pulling efficiency and equipment life.

[0004] 2) Insufficient clamping stability: For piles with irregular shapes or rough surfaces (such as concrete pipe piles, steel sheet piles, etc.), the traditional parallel clamping tooth layout is prone to slippage, causing operation interruption.

[0005] 3) Low centering accuracy: Some equipment clamping mechanisms do not fully consider eccentricity compensation when laid out laterally, which can easily cause the pile to tilt during pile driving or extraction, affecting the construction quality.

[0006] 4) Limited operating posture: The existing equipment is poorly compatible with the excavator, and the pitch and slewing degrees of freedom are insufficient, which makes it difficult to operate in narrow spaces or at special angles, reducing the versatility and adaptability of the equipment.

[0007] Therefore, there is an urgent need for an integrated back-cover type guardrail post pull-out vibrator with symmetrical structure, stable clamping, high centering accuracy, and multi-posture operation capability to solve the shortcomings of existing technologies. Utility Model Content

[0008] This utility model proposes an integral back cover type guardrail post pull-out vibrator, which aims to overcome the above-mentioned shortcomings of the existing technology and achieve symmetrical structure, stable clamping, high centering accuracy and multi-position operation capability.

[0009] The technical solution of this utility model is an integral back cover type guardrail post pull-out vibrator, which includes a symmetrical synchronous clamp, staggered tooth clamping structure, lateral eccentric arrangement and multi-degree-of-freedom adjustment design, so as to achieve uniform clamping, stable grip and high-precision centering of the pile body, and improve the adaptability of the equipment under multiple working conditions.

[0010] Specifically, the system includes a pitch boom, a slewing mechanism, a back-covered side support, a vibrator housing, and a symmetrical synchronous clamping mechanism. The upper end of the pitch boom is connected to the excavator's standard boom via a pitch adjustment mechanism. The lower end of the pitch boom is connected to the upper end of the slewing mechanism via a pin. The lower end of the slewing mechanism is connected to the upper end of the back-covered side support via a slewing pin. The vibrator housing is installed inside the back-covered side support, and its lower end is connected to the upper end of the symmetrical synchronous clamping mechanism via bolts. During operation, the symmetrical synchronous clamping mechanism clamps or releases the pile, controlling the sinking and pulling action. The vibrator housing uses high-frequency excitation to achieve pile sinking and pulling. The slewing mechanism is used to adjust the angle of the pile clamping position, and the pitch boom is used to adjust the pitch posture.

[0011] Preferably, a damping block is provided between the exciter housing and the back cover-type side support. This can buffer the impact force generated by high-frequency excitation and prevent damage to the drive body.

[0012] Preferably, the rotary mechanism includes a turntable body, a rotary motor, a rotary gear, and a positioning gear. The upper end of the turntable body is connected to the lower end of the pitch arm via a pin. The turntable body is equipped with a rotary motor on its side. The output end of the rotary motor is connected to the rotary gear located below the turntable body. The rotary gear meshes with the positioning gear. The positioning gear is connected to the upper end of the back cover-type side support via a rotary pin.

[0013] Preferably, the symmetrical synchronous clamping mechanism includes a clamping cylinder, synchronous connecting rods, synchronous teeth, and staggered clamping teeth. The middle portions of a pair of synchronous connecting rods are rotatably connected to both sides of the mounting frame. The upper ends of the two synchronous connecting rods are rotatably connected to the piston of the cylinder and the outer end of the clamping cylinder, respectively. Staggered clamping teeth are provided on opposite sides of the lower ends of the two synchronous connecting rods, and synchronous teeth are provided on opposite sides of the middle portions of the two synchronous connecting rods. The synchronous connecting rods on both sides are arranged eccentrically laterally. In the clamping position, the clamping cylinder drives the piston to extend, bringing the staggered clamping teeth of the two synchronous connecting rods closer together to clamp the top of the guardrail post pile. The clamping cylinder and piston drive the synchronous connecting rods and staggered clamping teeth to move synchronously, ensuring that the clamping force is evenly distributed on both sides of the guardrail post pile, avoiding uneven loading. The staggered layout of the staggered clamping teeth enhances the gripping stability of irregular piles and prevents slippage during driving and extraction. The eccentric arrangement of the synchronous connecting rods on both sides allows for automatic centering of the pile during driving or extraction operations.

[0014] Preferably, when in the pile driving position, the clamping cylinder drives the cylinder piston to retract, causing the staggered clamping teeth of the two synchronous connecting rods to open. The bottom of the mounting frame is equipped with a positioning pile cap, the shape of which matches the shape of the top of the guardrail post pile.

[0015] The advantages of this utility model are: 1) The symmetrical synchronous clamping mechanism makes the clamping force evenly distributed, which can avoid uneven load and extend the service life of the equipment. 2) The staggered tooth clamping structure improves the grip and anti-slip performance on irregular piles; 3) The lateral eccentric arrangement can improve the centering accuracy during the sinking and pulling process and improve the construction quality; 4) It is compatible with the standard boom of excavators and has 0-90° pitch adjustment and 360° continuous slewing function, which can significantly improve the multi-position operation capability and the scope of application. 5) Damping block connection can effectively buffer the excitation force and protect the core structure of the equipment from damage.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0023] like Figure 1-5 As shown, an integral back-cover type guardrail post pull-out vibrator has the following structure: a pitch arm 1, a slewing mechanism 2, a back-cover type side support 3, a vibrator housing 4, and a symmetrical synchronous clamping mechanism 5. The lower end of the pitch arm 1 is connected to the upper end of the slewing mechanism 2 by a pin, and the lower end of the slewing mechanism 2 is connected to the upper end of the back-cover type side support 3 by a slewing pin. The vibrator housing 4 is installed inside the back-cover type side support 3. A damping block 41 is provided between the vibrator housing 4 and the back-cover type side support 3. The lower end of the vibrator housing 4 is connected to the upper end of the symmetrical synchronous clamping mechanism 5 by a bolt group.

[0024] During operation, the symmetrical synchronous clamping mechanism 5 clamps or releases the pile body to control the sinking and pulling action. The vibrator box 4 realizes the sinking and pulling of the pile body through high-frequency excitation. The slewing mechanism 2 is used to adjust the angle of the pile clamping and positioning. The pitch arm 1 is used to adjust the pitch posture. The damping block 41 is used to buffer the impact force generated by high-frequency excitation to prevent damage to the drive body.

[0025] Specifically, the rotary mechanism 2 includes a turntable body 21, a rotary motor 22, a rotary gear 23, and a positioning gear 24. The upper end of the turntable body 21 is connected to the lower end of the pitch arm 1 via a pin. The rotary motor 22 is mounted on the side of the turntable body 21. The output end of the rotary motor 22 is connected to the rotary gear 23 located below the turntable body 21. The rotary gear 23 meshes with the positioning gear 24. The positioning gear 24 is connected to the upper end of the back cover-type side support 3 via a rotary pin.

[0026] The symmetrical synchronous clamping mechanism 5 includes a clamping cylinder 53, a synchronous connecting rod 55, a synchronous tooth 54, and an interlaced clamping tooth 58. The middle parts of a pair of synchronous connecting rods 55 are rotatably connected to both sides of the mounting frame 51. The upper ends of the two synchronous connecting rods 55 are rotatably connected to the piston of the cylinder 52 and the outer end of the clamping cylinder 53, respectively. Interlaced clamping teeth 58 are provided on opposite sides of the lower ends of the two synchronous connecting rods 55, and synchronous teeth 54 are provided on opposite sides of the middle part of the two synchronous connecting rods 55.

[0027] like Figure 2 As shown, when in the clamping position, the clamping cylinder 53 drives the cylinder piston 52 to extend, causing the staggered clamping teeth 58 of the two synchronous connecting rods 55 to approach and clamp the top of the guardrail post 57.

[0028] like Figure 3 As shown, when in the pile driving position, the clamping cylinder 53 drives the cylinder piston 52 to retract, causing the staggered clamping teeth 58 of the two synchronous connecting rods 55 to open, and the positioning pile cap 56 is installed at the bottom of the mounting frame 51. The shape of the positioning pile cap matches the shape of the top of the guardrail post pile body 57.

[0029] In the above structure, the clamping cylinder 53 and the cylinder piston 52 drive the synchronous connecting rods 55 on both sides and the staggered clamping teeth 58 to move synchronously, which can ensure that the clamping force is evenly distributed on both sides of the guardrail post pile 57 and avoid uneven load; the staggered layout of the staggered clamping teeth 58 can enhance the gripping stability of irregular piles and prevent the piles from slipping during the sinking and pulling process; the synchronous connecting rods 55 on both sides are arranged eccentrically in the lateral direction, which can realize the automatic centering of the pile during pile sinking or pulling operations.

[0030] In actual operation, the upper end of the pitch boom 1 is adapted to the standard boom of the excavator for installation. With the help of the slewing mechanism 2, it can achieve 360° continuous slewing. With the pitch adjustment mechanism (existing technology) set between the standard boom of the excavator and the pitch boom 1, it can achieve 0-90° pitch adjustment to adapt to multi-posture operation.

[0031] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
