Detailed Description
The technical solution and the advantages of the present invention will be described in detail with reference to the following embodiments.
The utility model provides a directional rig of level and be applied to directional rig of level's girder variable angle adjustment mechanism, as shown in figure 2, do the utility model discloses a preferred embodiment. The horizontal directional drilling machine comprises a chassis mechanism 1, a girder 2 and an angle-variable adjusting mechanism 3 capable of adjusting the angle of the girder, a power head 4 is also installed above the girder 2, and the chassis mechanism 1 is also usually installed on a walking power station 5. Wherein:
the girder 2 is supported and fixed by a girder bracket 6. The girder 2 can be installed on the girder bracket 6 through a slidable structure, the specific slidable structure can be that U-shaped sliding grooves are formed in two sides of the girder bracket 6, and two sides of the girder 2 are arranged in the U-shaped sliding grooves, so that the girder 2 slides forwards and backwards to limit the movement of the girder 2 up and down and two sides.
The variable angle adjusting mechanism 3 comprises a first amplitude changing mechanism 31, a second amplitude changing mechanism 32 and a floating oil cylinder 33. The first luffing mechanism 31 comprises a luffing connecting rod 311 and a first luffing oil cylinder 312, wherein one end of the luffing connecting rod 311 is hinged on the girder bracket 6, and the other end of the luffing connecting rod 311 is hinged on the chassis mechanism 1. One end of the first luffing cylinder 312 is hinged to the middle section of the luffing connecting rod 311, and the other end is hinged to the chassis mechanism 1. The second amplitude-varying mechanism 32 is a second amplitude-varying oil cylinder 321, one end of the second amplitude-varying oil cylinder 321 is hinged on the girder bracket 6, and the other end is hinged on the chassis mechanism 1. The floating oil cylinder 33 is hinged on the girder bracket 6, and one end of a piston rod of the floating oil cylinder is hinged on the girder 2. The first horn 31 may be provided at the low-side end of the girder 2, and the second horn 32 may be provided at the high-side end of the girder 2. In addition, because auxiliary support is not needed, two points of the variable angle adjusting mechanism 3 hinged with the girder bracket 6 can be positioned at the front end part and the rear end part of the girder bracket 6, so that the span is maximum, and the stability of transportation and construction is ensured.
Further, the chassis mechanism 1 includes a first beam 11 and a second beam 12. The other end of the first luffing cylinder 312 is hinged to the side surface of the first cross beam 11, specifically, the side surface of the first cross beam 11 is provided with a first hinge base 111, and the first luffing cylinder 312 is hinged to the first hinge base 111. The other end of the variable amplitude connecting rod 311 is hinged to the top end of the first cross beam 11, specifically, the top end of the first cross beam 11 is provided with a connecting rod hinge base 112, and the variable amplitude connecting rod 311 is hinged to the connecting rod hinge base 112. The other end of the second luffing cylinder 321 is hinged to the side surface of the second cross beam 12, specifically, a second hinge support 121 is arranged on the side surface of the second cross beam 12, and the other end of the second luffing cylinder 321 is hinged to the second hinge support 121. By adopting the structure, the amplitude-variable connection 311 of the first amplitude-variable mechanism 31 and the first amplitude-variable oil cylinder 312 are arranged on the same crossbeam (namely the first crossbeam 11), so that one supporting beam is omitted, the chassis structure is simpler, and the cost is lower.
In addition, a floating oil cylinder hinged support 21 can be further arranged on the girder 2, and a piston rod of the floating oil cylinder 33 is hinged on the floating oil cylinder hinged support 21.
As shown in fig. 3, when the angle of the girder 2 is to be adjusted, the horizontal directional drilling machine of the present invention controls the piston rod of the first luffing cylinder 312 to rise, and pushes the luffing connecting rod 311 to rotate clockwise, so that the left end of the girder bracket 6 rises; when the piston rod of the second luffing cylinder 321 is controlled to rise, the right end of the girder bracket 6 is pushed to rise until the girder bracket 6 reaches a required angle. When the anchoring plate 7 at the lower end of the girder 2 is not in contact with the ground, the piston rod of the floating cylinder 33 is retracted to pull the girder 2 to reach the ground.
The angle-variable adjusting mechanism with the structure can realize a wide range of angle variation because (as shown in figure 4): when the girder 2 is adjusted from a smaller 9 degrees to a larger 14 degrees, if the girder 2 and the girder bracket 6 are fixed structures, a larger oil cylinder stroke and a longer amplitude-variable connection are required, as shown in (b) and (c) of fig. 4, the required length of the amplitude-variable connecting rod 311 of the first amplitude-variable mechanism 31 and the required length of the stroke of the second amplitude-variable oil cylinder 321 of the second amplitude-variable mechanism 32 are both longer; and after the floating cylinder 33 is arranged, the floating cylinder 33 can drag the girder 2 to slide back and forth on the girder bracket 6, so that the girder 2 can be dragged backwards when the angle is adjusted to 14 degrees, thereby reducing the length of the luffing connecting rod 311 and the stroke of the second luffing cylinder 321, as shown in fig. 4 (d). That is to say, the amplitude variation connecting rod and the oil cylinder stroke with the same length can realize a larger angle variation range. As shown in fig. 4 (a), since the luffing mechanism provided with the luffing connecting rod of the present invention is installed at the lower end of the girder 2, and the length of the luffing connecting rod is reduced at the same time, when the girder 2 is lowered to the minimum, the inclination angle thereof is almost 0, thereby enlarging the whole variable angle range.
Above embodiment only is for explaining the utility model discloses a technical thought can not be injectd with this the utility model discloses a protection scope, all according to the utility model provides a technical thought, any change of doing on technical scheme basis all falls into the utility model discloses within the protection scope.
