Embodiment Construction
[0030] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] Such as Figure 1-3 As shown, a self-locking clamp includes a bracket 1 , a clamp 2 and a telescopic piece 3 ;
[0032] The number of clamps 2 can be designed according to the actual situation. The more clamps 2, the more stable the clamps 2 are when lifting and transporting the concrete guardrail. One clamp 2 corresponds to one telescopic part 3. If there are multiple telescopic parts 3, then All the telescopic elements 3 operate synchronously, so that the corresponding clamps 2 operate synchronously.
[0033] Clamp 2 comprises opposite first support arm 4, second support arm 5 and support plate 6; First support arm 4 ends and second support arm 5 ends are hinged, and first support arm 4 and second support arm 5 The first rotating shaft 7 is connected; the opposite second support arm 5 is arranged crosswise, and the second rotating shaft 8 is...

The invention relates to a self-locking type fixture, which comprises a support, at least one fixture, and a telescopic piece for controlling the fixture to open or close. The telescopic piece and thefixture are located on the support; the fixture comprises first support arms, second support arms and support plates arranged oppositely; one ends of the first support arms are hinged with one ends of the second support arms; the support plates are connected to the other ends of the second support arms; a base is arranged on the upper ends of the oppositely arranged first support arms; the firstsupport arms are hinged with the left side and the right side of the base; a first rotary shaft is arranged on a connecting part of each first support arm and each second support arm; the oppositely arranged second support arms are connected in a crossing way; and a second rotary shaft is arranged on a connecting part of the second support arms. Compared with the prior art, by matching with a forklift lifting and transshipping concrete guardrail mechanical installation manner, a large volume can be safely and effectively realized, a large-tonnage expressway medial strip concrete guardrail is quickly installed, and meanwhile, the fixture provided by the invention can realize self-locking, so that the concrete guardrail is more stable during an installation process, and operating personnel is safer.
Description
technical field [0001] The invention belongs to the technical field of clamps, in particular to a self-locking clamp and an installation method thereof. Background technique [0002] In modern bridge guardrails and highway guardrails, the anti-collision level is determined according to the grade of the road, considering its safety, coordination, characteristics of the object to be protected and geometric conditions on the spot, and then according to its own structure, economy and construction. Concrete guardrails are usually selected to be located on both sides of bridges and roads. As the stressed components of bridges and road guardrails, concrete guardrails have good characteristics of absorbing vehicle collision energy and are also easy to process. [0003] During the installation and construction of the concrete guardrail, because the concrete guardrail is large in size and weighs about 2.5 tons, the installation position is narrow, and the line type requirements after ...
