Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular to an auxiliary device for a guardrail pile driver. Background Technology

[0002] Corrugated beam guardrails play a crucial role in modern road safety protection, and their installation quality directly affects the protective effect and service life. Traffic safety facility projects are characterized by short construction periods and rapid project schedules, making guardrail pile drivers an indispensable key piece of equipment for achieving mechanized operations in modern transportation infrastructure.

[0003] Traditional guardrail pile drivers are hydraulically or diesel-powered, using high-frequency impact to quickly drive guardrail piles into the ground. During construction, workers must first erect the guardrail posts that were previously laid horizontally on the ground and move them to the precise installation position. Then, the hammer of the guardrail pile driver presses down on the top of the post, driving it downwards into the ground. The guardrail posts are heavy, making the process of erecting them labor-intensive and inefficient. Furthermore, the impact force from the hammer can easily cause the posts to tilt, resulting in poor installation accuracy and affecting the quality of the corrugated beam guardrail.

[0028] Figures 1 to 8 This invention illustrates an auxiliary device for a guardrail pile driver. The guardrail pile driver includes a vehicle body 1, with a guide rail frame 2 and a hammer module 3 mounted on one side of the vehicle body 1. The hammer module 3 is mounted on the guide rail frame 2 and can move up and down along the guide rail frame. A hammer body 31 is mounted at the bottom end of the hammer module 3. The guardrail pile driver also includes a power module. Driven by the power module, the hammer module 3 moves up and down along the guide rail frame 2 and applies impact force to the guardrail posts 6 through the hammer body 31.

[0029] like Figure 1 and Figure 2 As shown, the auxiliary device provided by this utility model includes a rigging 4 and a limiter 5. The forward direction of the guardrail pile driver is defined as forward. The rigging 4 is positioned in front of the hammer head module 3 and includes a sling 41 and a connector 42. The top end of the sling 41 is fixedly connected to the hammer head module 3, and the connector 42 is fixedly connected to the bottom end of the sling 41, hanging down to a position lower than the hammer body 31. The hammer head module 3 can drive the rigging 4 to move up and down. The connector 42 is used to connect to or disconnect from the top end of the guardrail post 6. When the connector 42 is connected to the top end of the guardrail post 6, the hammer head module 3 can drive the guardrail post 6 to move. The connector 42 is configured to connect to the guardrail post 6 lying horizontally on the ground and then, as the hammer head module 3 moves upward, erect the guardrail post 6.

[0030] During construction, the guardrail post 6 is laid horizontally on the ground beforehand, with its top end close to the installation position. The guardrail pile driver travels until the hammer module 3 is above the installation position and moves it downwards, bringing the connector 42 of the rigging 4 close to the top of the guardrail post 6. The workers then connect the connector 42 to the top of the guardrail post 6. If the connector 42 is too high, the top of the guardrail post 6 can be raised a certain height before connection. After confirming a stable connection between the connector 42 and the top of the guardrail post 6, the hammer module 3 moves upwards, lifting the horizontally laid guardrail post 6 using the rigging 4, making it upright in the installation position. Once the guardrail post 6 is stable, the hammer 31 is pressed against the top of the guardrail post 6, and a downward impact force is applied, driving the bottom of the guardrail post 6 into the ground. After the connector 42 detaches from the guardrail post 6, the guardrail pile driver can continue forward to install the next guardrail post 6.

[0031] The hammer module 3 is connected to the guardrail post 6 via the rigging 4. The upward movement of the hammer module 3 can erect the guardrail post 6, which is faster, replaces manual labor, and reduces labor intensity. Construction workers only need to connect the connector 42 to the top of the guardrail post 6, which makes the construction more efficient.

[0032] The limiter 5 is located below the hammer module 3 and is fixedly connected to the bottom of the guide rail frame 2. The limiter 5 has a limiting groove 50 that cooperates with the guardrail post 6. After the rigging 4 erects the guardrail post 6, the construction personnel can assist the guardrail post 6 in locking it into the limiting groove 50 to position it so that it is directly below the hammer body 31. During the process of the hammer module 3 applying force to the guardrail post 6, the limiter 5 can keep the guardrail post 6 upright, resulting in higher installation accuracy and ensuring the quality of the guardrail.

[0033] Specifically, the sling 41 is located in front of the hammer body 31, allowing the top of the guardrail post 6 to be closer to the hammer body 31 after being lifted. The sling 41 can be made of steel wire rope, chain, synthetic fiber rope, etc., and the connector 42 can be made of hooks, buckles, clamps, etc., connecting the top of the guardrail post 6 through hooking, snapping, clamping, etc. The rigging 4 and limiter 5 have a simple structure, are easy to install, have low cost, and high versatility, making them suitable for various types of guardrail pile drivers.

[0034] The top of the guardrail post 6 is usually provided with a mounting hole 61, which is used for subsequent installation of the guardrail panel. Specifically, the mounting hole 61 is located on the side of the top of the guardrail post 6, close to the top surface of the guardrail post 6, and the mounting hole 61 can be used to connect the connector 42 of the rigging 4.

[0035] In some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the connector 42 is a hook 421, which is used to attach to the mounting hole 61 on the side of the top of the guardrail post 6. The hook and the mounting hole 61 are easy to connect and disconnect, making it convenient and quick to use. Furthermore, since the hook is attached to the side of the guardrail post 6, it will not affect the contact between the hammer 31 and the top surface of the guardrail post 6.

[0036] Furthermore, such as Figure 2 The distance in the height direction between the bottom of the connector 42 and the bottom surface of the hammer 31 is greater than the distance from the top surface of the guardrail post 6 to the mounting hole 61. Specifically, when the rigging 4 hangs naturally, the position of the connector 42 is lower than the hammer 31, and the height difference between the bottom of the connector 42 and the bottom surface of the hammer 31 is D1; ​​the distance between the top surface of the guardrail post 6 and the mounting hole 61 is D2, D1 > D2. When the rigging 4 lifts the guardrail post 6 to an upright position, the connector 42 is hooked into the mounting hole 61. At this time, the bottom end of the guardrail post 6 contacts the ground, and the top surface of the guardrail post 6 is lower than the bottom surface of the hammer 31. The hammer head module 3 needs to move downward so that the bottom surface of the hammer 31 contacts the top surface of the guardrail post 6, applying force to the guardrail post 6. The rigging 4 moves downward with the hammer head module 3 and vibrates under the impact of the hammer 31, so the hook 421 can automatically disengage from the mounting hole 61. If the hook 421 fails to automatically detach from the mounting hole 61, the hook 421 can be removed by the construction personnel after the guardrail post 6 has been driven into the ground to the required height.

[0037] In some embodiments of this utility model, the top end of the sling 41 is detachably fixed to the front side of the hammer module 3. Specifically, the sling 41 is a chain, the top end of which is provided with a shackle. A hanging ring is fixedly provided on the front side of the hammer module 3, and the shackle is detachably connected to the hanging ring, which facilitates the installation and removal of the sling 4.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the limiting groove 50 of the limiter 5 is located directly below the hammer body 31, and its opening faces forward. Since the lifting cable 41 is located on the front side of the hammer head module 3, the guardrail post 6 is positioned slightly in front of the limiter 5 after being lifted, making it easier for it to fit into the limiting groove 50. To avoid interference between the guardrail post 6 and the limiter 5 during lifting, the guardrail post 6 can be placed on the ground in the front-to-back direction, with its top end close to the installation position (i.e., below the hammer head module 3) and its bottom end facing forward, thus preventing the guardrail post 6 from colliding with the limiter 5 during lifting. Furthermore, a protective layer, such as fabric or a rubber sleeve, can be provided on the surface of the limiter 5 to prevent scratches on the guardrail post 6.

[0039] In some embodiments of this utility model, such as Figure 5 , Figure 6 and Figure 7As shown, the limiter 5 includes a fixing member 51 and multiple replacement members 52. The fixing member 51 is fixedly connected to the bottom of the guide rail frame 2. One of the multiple replacement members 52 is detachably and fixedly connected to the fixing member 51. Each of the multiple replacement members 52 is provided with a limit groove 50. The limit grooves 50 of the multiple replacement members 52 are configured with different shapes to adapt to guardrail posts 6 of different shapes. For example... Figure 6 The replacement part 52 has a limiting groove 50 with an arc structure, which can be adapted to the cylindrical guardrail post 6. Figure 7 The replacement part 52 shown has a rectangular groove 50 that can be adapted to the square column guardrail post 6.

[0040] Furthermore, a reinforcing rib 53 can be provided on the limiter 5 to increase structural strength and ensure the stability of the limit groove 50. Specifically, the reinforcing rib 53 is provided on the fixing member 51 and is fixedly connected to the guide rail frame 2 to increase the installation stability of the fixing member 51. Specifically, the fixing member 51 and the replacement member 52 can be made of metal plate and fixedly connected by multiple screws, pins and other fasteners.
