Description

Technical Field

[0001] This utility model relates to a pile driver, specifically a side-clamping pile driver for highway guardrail maintenance, belonging to the technical field of highway guardrail maintenance equipment. Background Technology

[0002] During long-term use, highway guardrail posts (piles) may bend, loosen, or be damaged due to factors such as vehicle collisions, natural corrosion, and climate change, requiring timely replacement and maintenance.

[0003] Existing guardrail bollard removal equipment is mostly large in size and heavy in structure. It usually requires the cooperation of large engineering vehicles, has poor mobility, and is not suitable for rapid operation in narrow shoulders or temporarily closed sections of highways.

[0004] The above problems can be solved by using mobile operation vehicles with clamping mechanisms. However, existing clamping mechanisms mostly adopt front clamping, which makes it difficult to achieve efficient clamping and accurate positioning in the limited space of highways. In addition, the high-frequency vibration pulling process can easily cause severe vibration of the equipment body, affecting the stability and safety of the operation.

[0005] On the other hand, some existing clamping mechanisms have auxiliary support mechanisms that are arranged on one side or lack synchronous coordination functions, resulting in uneven force distribution, easy deviation or tilting, affecting the pulling efficiency and the integrity of the pile. Utility Model Content

[0006] This utility model proposes a side-clamping guardrail maintenance pile driver, which aims to overcome the above-mentioned shortcomings of the existing technology, so as to achieve a smaller size to adapt to mobile vehicles, and to achieve rapid positioning, progressive clamping and stable support in a limited working space.

[0007] The technical solution of this utility model is a lateral clamping guardrail maintenance pile machine. Its structure includes a vehicle-mounted workbench, a hydraulic power station, a positioning robotic arm, auxiliary support rods, a vibrator, a hydraulic motor, and a lateral clamp. The vehicle-mounted workbench is mounted on a vehicle, and the hydraulic power station and positioning robotic arm are installed on the workbench. The end of the positioning robotic arm extends towards one side of the vehicle and is connected to a mounting box. The vibrator is installed at the bottom of the mounting box, and a hydraulic motor is installed on the side of the vibrator. The lateral clamp is installed at the bottom, with its opening and closing direction parallel to the vehicle's direction. Auxiliary support rods are provided on both sides of the mounting box. The hydraulic power station drives the positioning robotic arm, auxiliary support rods, and vibrator respectively through a control system. The vehicle-mounted workbench, driven by the vehicle, loads all components and moves to the target guardrail pile location on the highway. The hydraulic power station, in conjunction with the vehicle-mounted workbench, drives the positioning robotic arm, auxiliary support rods, and vibrator through the control system to perform the pulling operation. The lateral clamp positions and guides the guardrail pile. A hydraulic motor connects to the vibrator, driving it to generate high-frequency vibrations to improve drawing efficiency. The auxiliary support rods move synchronously with the lateral clamps, simultaneously pressing down to assist clamping and stabilize the equipment during the clamping process. The auxiliary support rods employ a symmetrical, double-cooperative arrangement, achieving balanced force, smooth operation, and stable support during the drawing operation. The synchronous movement of the auxiliary support rods during clamping and drawing operations counteracts the impact of the high-frequency vibrations generated by the vibrator on the vehicle body.

[0008] Preferably, the lateral clamp has a stepped structure that abruptly changes from the end inward, with adjacent stepped surfaces forming a guide step. This is used to achieve self-positioning and rapid guidance when the guardrail post enters the lateral clamp.

[0009] The advantages of this utility model are: (1) The overall structure is compact and suitable for loading onto mobile work vehicles, allowing for flexible operation on highway shoulders or in narrow construction areas; (2) The side clamp adopts a stepped structure to achieve rapid positioning and guidance of the pile body. It can be combined with a progressive clamping method to effectively improve clamping stability and operational safety. (3) The auxiliary support rod moves synchronously with the clamp and adopts a symmetrical double cooperative structure, which can balance the force, reduce the vibration of the equipment body and ensure the stability and safety of the operation process.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0015] like Figure 1-3 As shown, a side-clamping guardrail maintenance pile driver includes a vehicle-mounted workbench 1, a hydraulic power station 2, a positioning robotic arm 3, auxiliary support rods 4, damping blocks 5, a vibrator 6, a hydraulic motor 7, and a side gripper 8. The vehicle-mounted workbench 1 is mounted on a vehicle, and the hydraulic power station 2 and the positioning robotic arm 3 are mounted on the workbench 1. The end of the positioning robotic arm 3 extends to one side of the vehicle and is connected to a mounting box. The vibrator 6 is mounted on the lower part of the mounting box, and the hydraulic motor 7 is mounted on the side of the vibrator 6. The side gripper 8 is mounted on the bottom, and the opening and closing direction of the side gripper 8 is parallel to the vehicle direction. Auxiliary support rods 4 are respectively provided on both sides of the mounting box. The hydraulic power station 2 drives the positioning robotic arm 3, the auxiliary support rods 4, and the vibrator 6 respectively through a control system 21.

[0016] The vehicle-mounted workbench 1 is used to load all components and move them to the location of the highway target guardrail post 9.

[0017] The hydraulic power station 2 works in conjunction with the vehicle-mounted workbench 1, and drives the positioning robotic arm 3, auxiliary support rod 4 and vibrator 6 to perform the pulling operation through the control system 21.

[0018] The positioning robotic arm 3 is installed on the vehicle-mounted workbench 1 and is used to position the guardrail post 9.

[0019] The lateral gripper 8 is located at the end of the positioning robotic arm 3 and features a stepped structure that abruptly changes inward from the end. Adjacent steps form guide steps, used for self-positioning and rapid guidance when the guardrail post 9 enters the lateral gripper 8. After positioning, a progressive clamping method is preferably used to fix the guardrail post 9. This progressive clamping method involves gradually increasing the clamping force under hydraulic drive to reduce impact on the guardrail post 9 and improve clamping stability.

[0020] The auxiliary support rod 4 moves synchronously with the side clamping jaw 8, simultaneously pressing down to assist in clamping and stabilizing the equipment during the clamping process. The auxiliary support rod 4 adopts a symmetrical double-cooperative arrangement, achieving balanced force, smooth operation, and stable support during the pulling operation. The synchronous movement of the auxiliary support rod 4 during clamping and pulling operations can counteract the impact of the high-frequency vibration generated by the vibrator 6 on the vehicle body.

[0021] The hydraulic motor 7 is connected to the vibrator 6, driving the vibrator 6 to generate high-frequency vibration to improve the drawing efficiency.

[0022] 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.

[0023] 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.
