Description

Technical Field

[0001] This utility model belongs to the technical field of highway engineering construction equipment, specifically relating to a detachable and adaptable uprighting and leveling positioning device for steel guardrail post piling construction. Background Technology

[0002] In the construction of steel guardrails for highway engineering, the positions of the guardrail posts are usually determined by surveying and setting out before being installed into the roadbed using a driving method. Construction specifications require that the posts have good verticality (horizontalness) to ensure the overall smoothness of the guardrail's alignment. However, the existing steel guardrail post piling construction process has many technical defects: First, collaborative work is inefficient. Traditional construction requires at least two workers: one uses pipe wrenches or other tools to hold and straighten the column, while the other uses a level (such as a spirit level) to check the verticality against the side of the column. Because the two workers' actions are difficult to synchronize perfectly, the column is prone to shifting during the straightening process, requiring repeated adjustments and greatly reducing construction efficiency.

[0003] Secondly, the accuracy of levelness detection is poor. The level measuring instrument requires manual close contact with the side of the column for detection. However, in actual construction, the surface of the column may be uneven. If the contact force or angle is inconsistent during manual contact, gaps or tilting may occur between the level and the column, thus introducing detection errors and affecting the accuracy of verticality control.

[0004] Furthermore, the versatility of straightening tools is insufficient. Existing straightening tools such as pipe wrenches typically have a single jaw shape, making it difficult to simultaneously adapt to steel guardrail posts with different cross-sectional shapes (such as common square steel posts and round steel pipe posts). When construction involves posts with various cross-sections, it is necessary to frequently change specialized tools, increasing preparation time and tool management costs before construction.

[0005] Finally, there is a high degree of operator fatigue. During the pile driving process, the pile driver's hammer strikes the column, generating significant vibrations. The personnel responsible for straightening the column need to continuously exert force to fix it with tools while simultaneously monitoring its levelness. This can quickly lead to hand and limb fatigue, further reducing the accuracy of the column straightening and leveling operations.

[0006] In summary, the current steel guardrail post piling construction lacks a dedicated device that can integrate functions such as "multi-section post adaptation, single-person synchronous straightening and leveling, and precise level detection," and there is an urgent need for technical improvements to solve the above problems. Utility Model Content

[0007] To address the problems in existing steel guardrail post piling construction, such as low collaborative work efficiency (requiring multiple people to cooperate in straightening and inspection), poor levelness detection accuracy (the level instrument directly touching the post is prone to errors due to uneven surfaces or contact deviations), insufficient versatility of straightening tools (difficult to adapt to posts with different cross-sections such as square and round), and high operator fatigue (large vibrations during piling and the need for continuous force), and considering the requirements of steel guardrail post construction for pre-layout positioning and ensuring verticality and smooth alignment during driving, this utility model aims to provide a detachable and adaptable straightening, leveling, and positioning device for steel guardrail post piling construction. By integrating straightening clamping and levelness detection functions, it enables single-person synchronous operation. To improve construction efficiency, the system completes column alignment and verticality testing. It utilizes detachable, adaptable positioning components with both right-angle and curved fitting parts to meet the alignment and horizontal benchmark establishment needs of columns with different cross-sections, enhancing versatility. Taking advantage of the positioning component's automatic horizontalization of the operating handle when it's in contact with the column, the level measuring instrument is integrated into the handle, avoiding errors caused by the level directly contacting the column and improving testing accuracy. Simultaneously, the handle structure is optimized to reduce operational force and alleviate fatigue caused by pile driving vibrations, ensuring construction stability and comfort, thereby reducing the workload of subsequent overall linear adjustments and adapting to steel guardrail column driving installation scenarios.

[0008] To achieve the above objectives, this utility model provides a detachable, adaptable, uprighting, leveling, and positioning device for steel guardrail post piling construction, comprising: The clamp body, as the main skeleton of the device, has a handle for the operator to grip; The clamping jaws are fixedly installed at the front end of the clamp body and are used to directly clamp the steel guardrail post, providing a stable clamping foundation for the post to be straightened. A detachable adapter positioning component is detachably connected to the front end of the clamp body in a direction perpendicular to the length of the clamp body. The detachable adapter positioning component has a fitting part on the side away from the clamp body. The fitting part is used to fit tightly against the outer surface of the steel guardrail post so that the steel guardrail post and the clamp body form a basic right angle shape, thus establishing a horizontal detection benchmark. A level mounting area is provided on the upper surface of the handle portion of the clamp body for mounting a level measuring instrument; A detachable level measuring instrument, which is detachably fitted with the level mounting area, is used to detect the verticality of the steel guardrail post based on the reference of the basic right-angle shape. A jaw locking assembly is disposed between the clamping jaws and the clamp body to adjust the clamping force of the clamping jaws and ensure that the clamping jaws are stably and securely attached to the steel guardrail post. The positioning locking assembly is located between the detachable adapter positioning component and the clamp body, and is used to fix the detachable adapter positioning component to the front end of the clamp body, maintaining the contact state between the fitting part and the steel guardrail post and the basic right angle between the post and the clamp body.

[0009] Furthermore, the detachable adapter positioning component includes two adapter types: The square column is fitted with a positioning component, the fitting part of which is a right-angled groove. The right-angled groove is fitted to the outer side of the square steel guardrail post. After fitting, the square steel guardrail post and the clamp body can stably form a basic right-angle shape. The cylindrical adapter positioning part has an arc-shaped groove for its fitting part. The arc-shaped groove fits the outer side of the circular steel guardrail post. After fitting, the circular steel guardrail post and the clamp body can stably form a basic right angle shape. The square column adapter positioning component and the cylindrical adapter positioning component have the same structural dimensions, and both can be detachably fixed to the front end of the clamp body through the positioning component locking assembly.

[0010] Furthermore, the level mounting area is provided with a magnetic or snap-fit ​​structure, and the bottom of the detachable level measuring instrument is provided with a magnetic base adapted to the magnetic structure or a snap-fit ​​protrusion adapted to the snap-fit ​​structure. The detachable level measuring instrument is fixed to the level mounting area by magnetic or snap-fit ​​engagement.

[0011] Furthermore, a rubber anti-slip pad is attached to the inner side of the clamping jaws, which is used to enhance the friction between the clamping jaws and the outer surface of the steel guardrail post.

[0012] Furthermore, the outer surface of the handle of the clamp body is covered with a shock-absorbing sleeve, and the inside of the shock-absorbing sleeve is equipped with a spring shock-absorbing core. The shock-absorbing sleeve is made of silicone and is used to absorb the vibration transmitted to the handle during the piling process.

[0013] Furthermore, the detachable level measuring instrument is a bubble level or an electronic level. The bubble level has two bubble observation windows on its front. The detection directions of the two bubble observation windows correspond to the left and right vertical directions and the front and back vertical directions of the steel guardrail post, respectively. This is used to detect the verticality deviation of the post in the two directions based on the basic right-angle shape of the post and the clamp body.

[0014] The present invention, by adopting the above technical solution, has at least the following beneficial effects: In this invention, the integrated design of clamping jaws, detachable adapter positioning parts and level measuring instrument enables a single person to simultaneously straighten and clamp the steel guardrail posts and check their verticality, eliminating the need for multiple people to work together. This avoids the repeated adjustments to the posts caused by the asynchronous actions of multiple people in traditional construction, and significantly improves construction efficiency.

[0015] This invention includes a square column adapter positioning part with a right-angled groove fitting part and a round column adapter positioning part with an arc-shaped groove fitting part, which can accurately adapt to steel guardrail posts with different cross-sectional shapes such as square and round. Moreover, the two positioning parts have the same structural dimensions and can be detachably fixed to the front end of the clamp body through the positioning part locking assembly. There is no need to equip separate tools for columns with different cross-sections, which enhances the versatility of the device and reduces the time for tool replacement and preparation before construction.

[0016] In this invention, after the detachable adapter positioning piece is attached to the steel guardrail post, the post and the clamp body can automatically form a basic right angle. The level measuring instrument performs verticality detection based on the stable benchmark of the "post-clamp body right angle", which avoids the detection error caused by the surface condition of the post or the deviation of manual attachment when the traditional level is directly attached to the post, thus improving the accuracy of verticality detection.

[0017] In this invention, the shock-absorbing sleeve wrapped around the outer surface of the clamp handle can absorb the vibration transmitted to the handle during the pile driving process. At the same time, the rubber anti-slip pad attached to the inner side of the clamp jaws enhances the friction with the outer surface of the steel guardrail post, so that the operator can keep the post stable without having to hold it tightly for a long time, reducing operator fatigue and ensuring the stability of the construction process.

[0018] In this invention, the jaw locking assembly can adjust the clamping force of the jaws, and together with the rubber anti-slip pad, it can ensure that the jaws are stably attached to the steel guardrail post and are not prone to slipping; the positioning locking assembly can firmly fix the detachable and adaptable positioning component to the front end of the jaw body, so that the contact part is continuously and tightly attached to the post, ensuring the stability of the "post-jaw body right angle shape", and providing a reliable foundation for the straightening and leveling of the post.
