Embodiment Construction

[0020] like Figure 1~2 As shown, the present invention is a curved paving device, which includes a paving scraper 2 fixed on a lifting frame 1, the paving scraper 2 is connected with a paving scraper fixed leg 4 through a reinforced steel 3, and the paving scraper is fixed The leg 4 is set on the lower end of the extended column 7 on the outside of the paving trolley 6 through the casing 5, and the paving scraper fixed leg 4 is also connected with the gantry 8, and the gantry 8 is provided with a traction mechanism 9 for the paving scraper 2. A height adjustment mechanism for the paving scraper 2 is arranged between the pipe 5 and the gantry 8 .

[0021] A preferred embodiment of the present invention is that the paving scraper 2 includes a parallel section parallel to the slope of the ditch, and an inclined section forming an angle with the slope, and the angle between the parallel section and the inclined section is 120°- 160°.

[0022] A further preferred embodiment of t...

Abstract

The invention discloses a bent paving scraper and a fixing and lifting device of the bent paving scraper. The fixing and lifting device comprises the paving scraper fixed to a lifting frame, the paving scraper is connected with a paving scraper fixing leg through reinforcing shape steel, the paving scraper fixing leg is arranged at the lower ends of lengthened upright columns outside a paving trolley in a sleeved mode through sleeves, the paving scraper fixing leg is further connected with a portal frame, the portal frame is provided with traction mechanisms of the paving scraper, and a paving scraper height adjusting mechanism is disposed between the sleeves and the portal frame. The fixing and lifting device is simple in structure, has three functions, saves investment and reduces labor cost. According to the shape of the bent paving scraper and a positioning device, a vertical rod is fully used for guiding and supporting, and transmission of various forces of the paving scraper is guaranteed. By means of the portal frame, compulsive lifting of the paving scraper is achieved, space on two sides and above the portal frame is reasonably used, and a lifting device is convenient to arrange. The paving scraper can be conveniently and smoothly inserted into a sand pile due to the bent section on the front portion of the paving scraper, and paving of filter sand to a wider direction can be achieved by inclining the paving scraper.

Description

technical field [0001] The invention relates to the field of hydropower station engineering construction machinery, in particular to a curved paving device. Background technique [0002] On the foundation surface of the large-scale canal project, the slope of the canal is leveled, according to the current situation of the groundwater level, according to the design, a layer of coarse sand filter material is generally laid to ensure the balance between the internal water pressure of the channel and the external groundwater pressure. The design value of the paving thickness of the coarse sand filter material ranges from 5cm to 20cm (excluding the groove part), and it must be flattened and compacted. In the prior art, this process is divided into two steps: the first step is to manually push and scrape the coarse sand accumulated on the top of the slope, and to ensure the thickness of the paving, angle steel or square pipes are also installed. In order to scrape to the prescrib...
