Technical Field
[0001] The utility model relates to a flat-pushing type tarpaulin capable of cleaning the inner wall of a muck truck tarpaulin, and belongs to the technical field of muck truck tarpaulin equipment. Background Technique
[0002] Muck trucks play an important role in urban construction for transporting sand, gravel, construction waste, etc. Muck trucks usually need to be covered with tarpaulins to prevent materials such as sand and gravel from spilling. Muck trucks without tarpaulins are prone to material spilling, dripping, and leaking during transportation, which not only pollutes the environment but also poses a threat to the safety of other road users. Tarpaulins are usually made of high-strength polyester or polyethylene plastic materials, with good toughness and softness. Installing automatic tarpaulins or manually covering the tarpaulins can effectively prevent these situations and reduce traffic violations caused by non-standard operations.
[0003] When the existing flat-pushing type tarpaulin of a muck truck is in use, when the tarpaulin covers the materials such as muck, the inner side of the tarpaulin will come into contact with the materials such as muck. When the humidity of the muck is relatively high, the materials such as muck are easily adhered to the inner side of the tarpaulin, which is difficult to clean, easily causes additional wear of the tarpaulin, and affects the smooth opening and closing of the tarpaulin when more adhesion occurs.

[0020] The present utility model is composed of a tarpaulin 1, a pulley bracket 2, a frame connecting plate 3, a moving bottom frame 4, a top shaft 5, a rotating arm 6, a cleaning brush 7, a first rotating rod 8, a fixed arm 9, a second rotating rod 10, a sliding groove 11, a rotating shaft 12, a lifting cross shaft 13, a shaft sleeve 14, and a pin shaft 15.
[0021] Figure 1 It is shown that a plurality of pulley brackets 2 are sequentially installed on the flat push light rails on both sides of the upper end of the muck truck carriage, and the pulley brackets 2 are in sliding fit with the flat push light rails. Both ends of a plurality of moving bottom frames 4 are respectively connected to the relative pulley brackets 2 on both sides of the flat push light rail, and are connected to the flat push light rail chain of the flat push type tarpaulin through the pulley brackets 2. The moving bottom frame 4 is pushed through the flat push light rail chain, so as to realize the storage or unfolding of the tarpaulin 1.
[0022] Figure 2 、 3 It is shown that a plurality of top shafts 5 are arranged in parallel and sequentially above a plurality of moving bottom frames 4. The plurality of top shafts 5 and the plurality of moving bottom frames 4 are arranged at intervals. Each end of each top shaft 5 has two turning arms 6 respectively. The two turning arms 6 are rotatably arranged in a crossed shape outside the top shaft 5. The upper end of the turning arm 6 is a ring, and the ring is sleeved on the shaft rod of the top shaft 5. The ring of the turning arm 6 is in sliding fit with the shaft rod of the top shaft 5. A horizontal rotating shaft 12 is fixed at the lower end of the turning arm 6, and a shaft sleeve 14 is welded to the inner side of the moving bottom frame 4 opposite to the lower end of the turning arm 6. The rotating shaft 12 at the lower end of the turning arm 6 is fitted in the shaft sleeve 14 on the inner side of the moving bottom frame 5, and the rotating shaft 12 and the shaft sleeve 14 are in rotational fit.
[0023] Figure 2 、 3 It is shown that the two turning arms 6 at each end of the top shaft 5 are respectively rotatably connected to the two ends of the two moving bottom frames 4 on both sides of the top shaft 5 to form a triangular support structure, and the tarpaulin 1 continuously covers above the plurality of turning arms 6 and the top shaft 5. When the moving bottom frames 4 on both sides move closer, the top shaft 5 and the turning arms 6 move upward, and the tarpaulin 1 is folded; when the moving bottom frames 4 on both sides separate from each other, the top shaft 5 and the turning arms 6 descend, and the tarpaulin 1 is flattened accordingly.
[0024] Figure 2 、 3 It is shown that a first rotating rod 8 and a second rotating rod 10 are respectively installed between the two ends of the two opposite moving bottom frames 4. The rear ends of the two first rotating rods 8 and the two second rotating rods 10 are respectively sleeved on the outer ends of the rotating shafts 12 connecting the moving bottom frames 4 and the lower ends of the turning arms 6, and are also rotatably connected to the rotating shafts 12. The rotating shaft 12 is the common rotating connection shaft of the moving bottom frames 4, the lower ends of the turning arms 6, and the first rotating rod 8 and the second rotating rod 10.
[0025] Figure 2 、 3 It is shown that the lengths of the first rotating rod 8 and the second rotating rod 10 are greater than the length of the turning arm 6, which is convenient for when the turning arm 6 rotates to the horizontal state, that is, when the tarpaulin 1 is completely flattened and unfolded, the first rotating rod 8 will not affect the rotation of the turning arm 6, and prevent the problem that the turning arm 6 cannot be completely horizontally unfolded.
[0026] Figure 2 、3 It is shown that lifting horizontal shafts 13 are respectively connected between the front ends of two first rotating rods 8 and two second rotating rods 10 between two relatively moving bottom frames 4. Both ends of the two lifting horizontal shafts 13 are rotatably connected to the front ends of the two first rotating rods 8 and the two second rotating rods 10 respectively. The middle of each lifting horizontal shaft 13 is fixedly connected to the rear ends of two fixed arms 9 respectively. The two fixed arms 9 and the lifting horizontal shaft 13 are of an integral structure. The included angle between the two fixed arms 9 is fixed. The front ends of the two fixed arms 9 are respectively rotatably connected to the cleaning frames 7 on both sides.
[0027] Figure 2 、 3 It is shown that the cleaning brush 7 is composed of a bottom plate and bristles. The bottom plate is a rectangular plate. The plate surface of the bottom plate is parallel and opposite to the tarpaulin 1. Bristles are evenly distributed on the front of the bottom plate and are in contact with the tarpaulin 1. Sliders are fixedly connected to both ends of the front of the bottom plate respectively. Pin shafts 15 are respectively arranged at both ends of the rear of the bottom plate and are rotatably connected to the front ends of the two fixed arms 9.
[0028] The using process of the utility model is as follows:
[0029] When the flat-pushing type tarpaulin of the muck truck is used, it is connected to the flat-pushing light rail chain of the flat-pushing type tarpaulin through the pulley bracket 2, and the movement of the moving bottom frame 4 is realized through the flat-pushing light rail chain;
[0030] When the tarpaulin 1 is laid flat, the distance between two opposite moving bottom frames 4 becomes larger. Two swing arms 6 rotate outward around the top shaft 5. At the same time, the top shaft 5 descends, and the tarpaulin 1 unfolds and is gradually laid flat. At this time, the first rotating rods 8 and the second rotating rods 10 on two opposite moving bottom frames 4 also rotate around the lifting horizontal shaft 13. At the same time, the lifting horizontal shaft 13 descends. The descent of the lifting horizontal shaft 13 will drive the fixed arms 9 and the cleaning brush 7 to descend together. The bristles of the cleaning brush 7 are in contact with the inner wall of the tarpaulin 1, and the inner wall of the tarpaulin 1 is brushed.
[0031] On the contrary, when the tarpaulin 1 is stored, the distance between the moving bottom frames 4 gradually becomes smaller. Two swing arms 6 rotate inward around the top shaft 5. At the same time, under the push of the swing arms 6, the top shaft 5 will rise and lift, and the tarpaulin 1 is folded. At this time, the first rotating rods 8 and the second rotating rods 10 on two opposite moving bottom frames 4 also rotate around the lifting horizontal shaft 13. The bottoms of the first rotating rods 8 and the second rotating rods 10 also gradually approach, so that the lifting horizontal shafts 13 at their tops rise, driving the fixed arms 9 to rise. The cleaning brush 7 connected to the front end of the fixed arm 9 slides upward under the guidance of the chute 11 of the swing arm 6, and the bristles brush the inner wall of the tarpaulin 1 outside the cleaning brush 7, removing the sundries on the inner wall of the main body of the tarpaulin 1, and avoiding the problems that the adhesion damages the tarpaulin and affects the folding of the tarpaulin.
