Abstract
The utility model relates to ground construction equipment, in particular to a motion guiding device for a ground lateral groove milling device. An angle-turning device for a ground lateral groove milling device is used for driving the arc motion of a power head and a milling rod. The angle-turning device for a ground lateral groove milling device is characterized in that the angle-turning device for a ground lateral groove milling device mainly comprises a turning oil cylinder, the upper end of the cylinder body of the turning oil cylinder is pivoted with a fixed point through a pin shaft, and the piston rod end of the turning oil cylinder and the upper end of the power head are hinged together. The utility model is simple in structure, can enable the ground laterally-grooving device to successfully rotate around a point in a vertical plane in a mine to ensure the accurate completion of the ground laterally-grooving operation.
Description
Technical field
The utility model relates to underground construction equipment, relates in particular to the motion guide device of underground lateral trenching and milling device.
Background technology
Along with urban construction, subterranean cable, pipeline, subway construction emerge in an endless stream, and these often all are to be embedded in some degree of depth under the face of land, need to avoid the under ground portion of numerous buildings in construction; And because the construction period difference, and the requirement difference of underground installation, each length of embedment that is provided with is different again, often some facility need be constructed in the facility bottom that other is buried underground in advance, in this occasion, especially should be noted that and to damage existing facility, seriously influence otherwise can bring to the city.
Traditional, people generally adopt and dig earlier a dell vertically downward, and the dell bottom is lower than the lowest part of existing facility, then position as requested, laterally dig the passage or the space of the new facility that rises abruptly, modal is the Suporting structure that underground pipeline is used.Yet, the Suporting structure cost is high, needs the track of default shield machine structure transverse movement in the construction, the structure more complicated, employ Suporting structure for equipment such as cable, optical cables and seem and waste one's talent on a petty job, therefore need stronger, the lower-cost facility of a kind of specific aim of exploitation.Someone imagines to adopt and mills pin rod and mill pin and go out underground tank, but underground tank generally has certain requirement to height and width, and it is less to mill the pin rod diameter, only can move up and down, and can't satisfy size and required precision.
Summary of the invention
The utility model is intended to solve the above-mentioned defective of prior art, and a kind of underground lateral trenching and milling device angle station is provided.The utility model is simple in structure, and the underground lateral trough forming system is successfully rotated around any in vertical plane in the hole, ensures accurately finishing of underground lateral grooving work.
The utility model is achieved in that a kind of underground lateral trenching and milling device angle station, its circular motion in order to drive unit head and to mill pin rod, it mainly comprises a corner oil cylinder, its cylinder body upper end is pivotally connected on a fixed point by a bearing pin, and its tailpiece of the piston rod is in the same place with described unit head upper end hinge.
Described underground lateral trenching and milling device angle station, the cylinder body upper end of described corner oil cylinder are sat with a fixing ear and are connected with bearing pin.
Described underground lateral trenching and milling device angle station, the piston rod of described corner oil cylinder is connected with bearing pin by otic placode with unit head.
Described underground lateral trenching and milling device angle station, described angle station, unit head and mill pin rod and be suspended on the steel wire end that can move up and down.
The riding position uniqueness of the utility model oil cylinder, the cylinder head of oil cylinder are sat with the ear on being welded on saddle and are connected with bearing pin, and piston rod is connected with bearing pin with otic placode on the unit head.When the oil cylinder piston bar is stretched under the effect of foot back at control valve to fit the circular arc milling that just realizes the milling bar when quantitatively shrinking.When the oil cylinder piston bar be retracted to spacing after, utilize the quantitative milling of side direction that just realizes the milling bar under the effect of other feed cylinder.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is the utility model schematic diagram;
The specific embodiment
Show as Fig. 1: a kind of underground lateral trenching and milling device angle station, its circular motion in order to drive unit head 1 and to mill pin rod 2, it mainly comprises a corner oil cylinder 3, its cylinder body upper end is pivotally connected on a fixed point 4 by a bearing pin, and its tailpiece of the piston rod is in the same place with described unit head 2 upper end hinge.
In an embodiment of the present utility model, the cylinder body of described corner oil cylinder 3 upper end is sat with an ear as fixed point 4 and is connected with bearing pin; The piston rod of described corner oil cylinder 3 is connected with bearing pin 5 by otic placode with unit head 1.Described angle station, unit head 1 and mill pin rod 2 and be suspended on the steel wire end (failing among the figure to illustrate) that can move up and down.
During use, when with wire rope package unit being promoted, corner oil cylinder 3 piston rods are stretched foot can make the barycenter of device be in the equilbrium position; When corner oil cylinder 3 piston rods are stretched the circular arc milling that just realizes milling bar 2 when quantitatively shrink so that corresponding device thereof is suitable the foot back; When corner oil cylinder 3 piston rods be retracted to spacing after, under the effect of feed cylinder, just realize the quantitative milling of side direction of milling bar.
