Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1
As shown in FIGS. 1 to 5, a height adjusting device 8 for a machine body comprises a first driving member 85, a sliding block 81, a sliding block seat 82, a second driving member 84, a limiting member 83, a hinge seat 86, a hinge shaft 87, a sliding rod 88, and an installation seat 811,
the sliding block seat 82 is fixedly arranged on the machine body 2, a sliding groove for the sliding block 81 to slide is formed in the middle of the sliding block seat 82, 2 limiting holes are formed in the side portion of the sliding block seat 82, and a matching hole is formed in the side portion of the sliding block 81; in this embodiment, the limiting hole is formed on the slider seat 82 on a side close to the limiting member 83. The slider 81 and the slider holder 82 constitute a sliding pair.
The bottom end of the sliding block 81 is embedded into the sliding groove, and the top end of the sliding block 81 is fixed on the traveling device 7;
one end of the first driving piece 85 is fixed on the side part of the machine body 2, and the other end is connected with the middle part of the sliding block 81; in the embodiment, two ends of the first driving element 85 are respectively hinged to the body 2 and the sliding block 81.
One end of the second driving member 84 is connected with the body 2, the other end of the second driving member 84 is fixedly connected with the limiting member 83, and the second driving member 84 drives the limiting member 83 to sequentially pass through the limiting hole and the matching hole;
the hinged seat 86 is fixed at the front end of the walking device 7, the mounting seat 811 is fixed on the machine body 2,
a groove for embedding the sliding rod 88 is arranged in the mounting seat 811, one end of the sliding rod 88 is hinged with the hinge seat 86 through a hinge shaft 87, and the other end of the sliding rod 88 is slidably arranged in the groove for adjusting the position of the machine body 2 and the traveling device 7 in the X direction. The slide rod 88 and the body 2 constitute a slide pair. The slide rod 88 rotates about the axis of the Y-axis of the hinge base 86.
Specifically, one end of the sliding rod 88 is hinged to the hinge seat 86, and the other end is slidably disposed in the groove, which may be replaced by a sliding bearing fixed on the machine body 2 or a sliding rail, and the sliding rod 88 may move slightly inside the sliding rod. For example, the joint bearing is used for equivalent replacement (the inner ring of the joint bearing can rotate at a small angle relative to the outer ring), specifically, one end of the sliding rod is directly fixed on the walking device, the other end of the sliding rod is inserted into the joint bearing, and the outer ring of the joint bearing is fixed on the mounting seat. Two degrees of freedom of rotation in the Y-axis direction and movement in the X-axis direction are also obtained. When the body rotates, the sliding rod rotates around the hinged shaft and slides along the axial direction of the circular sliding chute X relative to the body, and the sliding direction is changed all the time because the body rotates. And can slide back and forth in the body 2 to compensate for a slight play of the body 2 in the front-rear direction during height adjustment.
In this embodiment, the limiting members 83 are two limiting pins, and the two limiting pins are disposed in parallel. One of the preferred modes is as follows: the distance between the axes of the two limiting pins is equal to the distance between the two limiting holes. The diameter of the limiting pin is the same as that of the limiting hole and the matching hole.
The quantity of spacing round pin is unanimous with the quantity of the spacing hole on the slider seat 82, and the number in spacing hole has decided the figure of fuselage height control position, and the quantity of preferred spacing round pin is 2 in this embodiment, and is corresponding, sets up 2 spacing holes on the slider seat 82, has decided that fuselage 2 has two height control positions. As shown in fig. 3, the fuselage 2 is in the raised position; as shown in fig. 4, the body 2 is in a low position.
When the height is adjusted, the second driving member 84 retracts to drive the limiting pin to be drawn out from the matching hole of the slider 81 and retract into the limiting hole of the slider seat 82, so as to ensure the guiding function of the limiting hole on the slider seat 82. The slider 81 can move up and down along the inside of the slider seat 82 by the first driving member 85. The height between the body 2 and the running gear 7 is adjusted by changing the length of the first driving member 85.
When the height of the machine body 2 is adjusted, the limit pin is pushed by the second driving member 84 to be inserted into the limit hole of the slider seat 82 and the fitting hole (not shown) of the slider 81 in sequence, so as to limit the vertical displacement of the slider 81.
In this embodiment, the groove is a U-shaped groove, the opening end of the U-shaped groove is fixedly provided with the block 89, and the block 89 is fixed at the opening end of the U-shaped groove by the fixing pin 810;
one side of the block 89 is provided with a semicircular groove matched with the U-shaped groove, and the semicircular groove and the semicircular part of the U-shaped groove form a circular sliding groove allowing the sliding rod 88 to slide. The block 89 is disposed in a U-shaped groove of the mounting seat 811, and the slide bar 88 moves only in the X direction. The fixing pin 810 fixes the block 89 to the mounting seat 811.
Specifically, including articulated seat 86 rear end welding on running gear 7 in this embodiment, set up the through-hole that supplies articulated seat 86 rear end to inlay to establish on running gear 7, articulated seat 86 rear end is fixed with running gear 7 through welding mode after stretching into the through-hole.
In this embodiment, the first driving member 85 is a hydraulic cylinder. The force required by the first drive member 85, which is relatively large, preferably a hydraulic ram, can also be replaced by an electric element which meets the power requirements.
Preferably, the second drive member 84 is a hydraulic ram in this embodiment. The hydraulic cylinder can also be replaced by an electric element which meets the power requirement, such as an electric push rod.
Fuselage height-adjusting device 8 can adjust the height of fuselage 2 and then improve the discharge gate position:
when the height of the machine body rises, the machine body 2 rotates relative to the walking device 7 along the Y-axis negative direction to drive the sliding rod 88 to rotate downwards relative to the hinge seat 86 clockwise along the Y-axis negative direction, and the machine body 2 can slightly move along the X-axis negative direction while rotating, so that the length of the sliding rod 88 embedded into the circular sliding chute is increased;
when the fuselage height descends, the fuselage 2 rotates along Y axle positive direction for running gear 7, drives slide bar 88 for articulated seat 86 rotates along Y axle positive direction clockwise, can produce when fuselage 2 rotates and follow X axle positive direction micrometric movement, makes the length of slide bar 88 embedding circular spout reduces.
When the height of the body changes, the sliding rod 88 is always embedded in the circular sliding groove.
A paver comprises the machine body height adjusting device 8, and a receiving device 1, a machine body 2, a ceiling assembly 3, a material conveying and distributing device 5, a leveling device 6 and a screed 4 which are sequentially arranged on the paver from the front end to the rear end, wherein a walking device 7 is positioned at the bottom of the machine body 2, one side of the leveling device 6 is fixedly arranged at the side part of the walking device 7, and the other side of the leveling device is connected with the screed 4; the material conveying and distributing device 5, the ceiling assembly 3 and the material receiving device 1 are all arranged above the machine body 2; the body height adjusting device 8 is arranged between the body 2 and the traveling device 7.
