[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Reference Figures 1-3 This utility model provides a portable anti-collision guardrail post driver, comprising:

[0029] A circular metal plate 1 is fixedly installed at the end of the steel bar of the excavator breaker hammer; in this embodiment, the circular metal plate 1 is welded and fixed to the end of the steel bar.

[0030] The clamp sleeve 2 is fixedly installed on the end of the circular metal plate 1 away from the steel bar. Several positioning holes 3 are opened on the side wall of the clamp sleeve 2. The clamp sleeve 2 is sleeved on the outside of the corrugated guardrail post. The clamp sleeve 2 is made of four steel plates with a specification of 300mm*160mm*10mm assembled into a square clamp with an outer side length of 17cm and an inner side length of 15cm.

[0031] Fasteners are provided in several parts. Several fasteners are installed on the outer wall of the clamp sleeve 2. Several fasteners pass through several positioning holes 3 respectively. The clamp sleeve 2 and the corrugated guardrail post are detachably connected by several fasteners.

[0032] The cross-sectional shape of the clamp sleeve 2 and the cross-sectional shape of the corrugated guardrail post are both rectangular;

[0033] With this configuration, during construction, after the column is inserted into the clamp sleeve 2, the clamp sleeve 2 and the corrugated guardrail column are fixed by several fasteners, and the corrugated guardrail column is lifted by an excavator, eliminating the safety risks of falling and being crushed caused by manual handling, avoiding construction deviations caused by manual adjustment, and improving the construction efficiency and quality of the corrugated guardrail column.

[0034] This utility model is based on the modification of existing excavator breakers, eliminating the need to purchase dedicated pile drivers, effectively reducing equipment investment costs. It is especially suitable for small and medium-sized projects or short-term projects, and can be quickly transferred to different construction sites by excavator, reducing transportation costs.

[0035] Further optimization of the scheme: the cross-sectional shape of the corrugated guardrail post is square, and the difference between the outer contour side length of the corrugated guardrail post and the inner contour side length of the clamp sleeve 2 is 15mm to 25mm; in this embodiment, it is preferably 20mm, wherein the outer contour side length of the corrugated guardrail post is 130mm and the inner contour side length of the clamp sleeve 2 is 150mm.

[0036] The guardrail post and the clamp sleeve 2 form a suitable gap. This gap can ensure that the post can be smoothly inserted into the clamp sleeve 2, and can also be tightly fixed by subsequent fasteners to prevent the post from shaking.

[0037] The scheme is further optimized so that there are four fasteners, which are installed axially at equal intervals on the outer wall of the clamp sleeve 2.

[0038] In a further optimized design, fasteners are made of bolts, and four bolt holes are provided on the outer wall of the column. The four bolts are threaded into the four bolt holes respectively. The inner diameter of the bolt holes is 20mm to 24mm; in this embodiment, it is preferably 22cm.

[0039] In a further optimized design, the positioning hole 3 of the clamp sleeve 2 has a circular cross-sectional shape and an inner diameter of 28mm to 32mm; in this embodiment, it is preferably 30cm.

[0040] Further optimization of the scheme: the circular metal plate 1 is made of circular steel plate with an outer diameter of 25cm to 30cm; in this embodiment, it is preferably 26cm; the circular metal plate 1 is welded to the end of the steel bar of the excavator breaker to ensure stable transmission of impact force, and the size of the circular metal plate 1 is compatible with the diameter of common excavator steel bars, which is convenient for modification.

[0041] Example 2

[0042] Reference Figure 4The difference between this embodiment and Embodiment 1 is that the cross-sectional shape of the positioning hole 3 is rectangular, the width of the positioning hole 3 is 28mm to 32mm, and the length of the positioning hole 3 is 50mm to 80mm. In this embodiment, the width of the positioning hole 3 is preferably 30cm, and the length is preferably 60mm. The rectangular positioning hole 3 ensures that the bolt can be smoothly inserted. The device of this invention can effectively replace the work of a column pile driver, and because the column is fixed with bolts, at least one person's labor can be reduced. The excavator uses on-site equipment, and can continue to perform other work after the work is completed, saving rental or purchase costs.
