The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, the invention provides a kind of paver, the front apron 30 that this paver comprises casing 10 and is positioned at casing 10 rears, is formed with between front apron 30 and casing 10 for the hammer ram mechanism installing space of hammer ram mechanism is installed.For make front apron 30 bottoms scraper plate 31 can and drift 70 between keep in touch, paver provided by the invention also comprises take-up device 20, this take-up device 20 also comprises the pulling force adjusting portion 22 that is arranged on the elastic tensioning mechanism in hammer ram mechanism installing space and is positioned at hammer ram mechanism installing space outside, elastic tensioning mechanism comprises elastic tensioning part 21, wherein, the first end of elastic tensioning part 21 is connected with front apron 30, and the second end of elastic tensioning part 21 is connected with pulling force adjusting portion 22.Cai for make elastic tensioning part 21 only in needs in tensioning state, and idle time, remove tensioning, above-mentioned pulling force adjusting portion 22 has to be made the primary importance of elastic tensioning part 21 in tensioning state and makes elastic tensioning part 21 in removing the second place of tensioning state.
As shown in Figures 3 to 5, paver provided by the invention, owing to pulling force adjusting portion 22 being arranged on to hammer ram mechanism installing space outside, divide and be arranged with hammer ram mechanism, can avoid interfering in operation pulling force adjusting portion 22Shi Yu hammer ram mechanism, and, as can be seen from Figure 1, as a kind of concrete embodiment, in the present invention, pulling force adjusting portion 22 has been arranged on to the inside of casing 10, because the clearance spaces in casing 10 is larger, and in non-complete totally enclosed state (side shown in Fig. 1 is opening-wide state), convenient operation personnel operate at any time to pulling force adjusting portion 22, the tensioning of adjustable elastic tension part 21 or relaxed state in real time.
In order to realize tension effect, above-mentioned elastic tensioning mechanism also comprises: the first pull bar 23 and the second pull bar 25, the first pull bar 23 is connected between the first end and front apron 30 of elastic tensioning part 21, and the second pull bar 25 is connected between second end and pulling force adjusting portion 22 of elastic tensioning part 21.Utilization is arranged on first pull bar 23 at elastic tensioning part 21 two ends and the second pull bar 25 and realizes rigidity and combine with elasticity, can guarantee reliable connection, can play again the effect of buffering.
For the ease of the dismounting of front apron 30, the first end of the first pull bar 23 and front apron 30 removably connect.
In order to realize removably connecting between the first end of the first pull bar 23 and front apron 30, elastic tensioning mechanism also comprises connection keeper 27, connect the draw-in groove that is formed with an end opening on keeper 27, the first end of the first pull bar 23 has the flange 23a extending radially, and flange 23a is arranged in draw-in groove so that the first end of the first pull bar 23 and front apron 30 removably connect.
In order to realize being connected between elastic tensioning part 21 and the first pull bar 23 and the second pull bar 25, the second end of the first pull bar 23 has the first connection ring portion 23c, the first end of elastic tensioning part 21 has the second connection ring portion 21a, and second connects ring portion 21a is connected between ring portion 23c connected by the first bolt 29a with first; Same, the first end of the second pull bar 25 has the 4th and connects ring portion 25a, and the second end of elastic tensioning part 21 has the 3rd and connects ring portion 21c, and the 4th connects ring portion 25a is connected between ring portion 21c and connects by the second bolt 29c with the 3rd.Utilize bolt to realize being connected between elastic tensioning part 21 and two pull bars, be convenient on the one hand dismounting, there is on the other hand reliable bonding strength, and compact conformation, installing space can be saved.
Because elastic tension part 21 is after long-time use, elasticity can reduce, and in order to promote the elastic force of elastic tension part 21 by simple adjustment, paver provided by the invention, also comprises fine setting sleeve 24.The first end of fine setting sleeve 24 is positioned at hammer ram mechanism installing space and is set in the periphery of elastic tensioning mechanism, the periphery of fine setting sleeve 24 is formed with the first fine tuning structure, on the inwall of casing 10, be formed with match with the first fine tuning structure so that the second end distance of finely tuning sleeve 24 fine-tuningly near or the second fine tuning structure of moving away from the direction of hammer ram mechanism installing space and, elastic tensioning part 21 is telescopically arranged in fine setting sleeve 24 with the movement of the second end of fine setting sleeve 24.When elastic tensioning part 21 aging, when elasticity weakens, can by adjusting, finely tune the installation site of the inwall of sleeve 24 and casing 10, second end of finely tuning sleeve 24 is moved to the direction away from hammer ram mechanism installing space, thereby elastic tensioning part 21 is shunk, increase the elasticity of elastic tensioning part 21.
For the ease of regulating, and cost-saving, above-mentioned the first fine tuning structure is the thread segment 24a that is arranged on fine setting sleeve 24, and the second fine tuning structure is the screwed hole being arranged on the inwall of casing 10, and the second end of fine setting sleeve 24 is through screwed hole and be positioned at hammer ram mechanism installing space outside.
The mode of utilizing screw thread and screw to cooperatively interact realizes the movement of fine setting sleeve 24, simple in structure, is easy to realize.
