The invention discloses a wrecker and a platform telescopic mechanism. The wrecker comprises a frame and a platform, the frame and platform are in sliding connection, a telescopic oil cylinder is arranged on the frame; the piston end of the telescopic oil cylinder is fixedly connected with the frame; a cylinder barrel of the telescopic oil cylinder is slidably connected with the frame; when telescopic oil cylinder stretches or contracts, a cylinder barrel of the telescopic oil cylinder slides along the frame; a pulley is arranged on the telescopic oil cylinder; the pulley is rotationally arranged on the oil cylinder through a rotating shaft; inhaul cables are connected between the frame and the platform; one end of each inhaul cable is fixedly connected with the frame, the other end of theinhaul cable is connected with the platform after bypassing the pulley, a rotating shaft of the pulley is perpendicular to the platform in the sliding direction of the frame, at least the extending inhaul cable and the retracting inhaul cable are included, the two ends of the extending inhaul cable are arranged in the first side of the wound pulley, and the two ends of the retracting inhaul cableare arranged in the second side of the wound pulley. According to the mechanism, platform stretching is achieved through the single cylinder with the inhaul cables, under the condition that the sameplatform stretching length is achieved, the oil cylinder stroke can be shortened by half, and the platform stretching efficiency is doubled.

    本发明一种清障车及平台伸缩机构,包括车架和平台,车架和平台滑动连接,在车架设置有伸缩油缸,伸缩油缸的活塞端固定连接车架,伸缩油缸的缸筒滑动连接车架,伸缩油缸伸缩时,伸缩油缸的缸筒沿车架滑动,在伸缩油缸上设置有滑轮,滑轮通过转轴转动设置在油缸上,在车架和平台之间连接有拉索,拉索一端固定连接车架,另一端绕过滑轮后连接平台,滑轮的旋转轴与平台沿车架滑动方向垂直,拉索至少设置有两根,分别为伸出拉索和缩回拉索,伸出拉索的两端均置于所绕滑轮的第一侧,缩回拉索的两端均置于所绕滑轮的第二侧。该机构通过单缸带拉索实现平台伸缩,在实现相同的平台伸缩长度下,油缸行程可缩短一半,平台伸缩效率提高一倍。
