Abstract
The utility model relates to ground construction equipment, in particular to a motion guiding device for a ground lateral groove milling device. A feed device for a ground lateral groove milling device is used for sending a laterally-grooving device to a certain depth. The laterally-grooving device mainly comprises a guide frame, a milling device on the guide frame and an adjusting valve of the milling device. The motion guiding device is characterized in that the motion guiding device mainly comprises a feed oil cylinder, the upper end of the feed oil cylinder is provided with a top seat which is connected with a steel cable, and the lower end of the piston rod of the feed oil cylinder is provided with an ear base which is fixed on the guide frame. The utility model is simple in structure, and can accurately feed the ground laterally-grooving device to a certain height to complete the grooving operation.
Description
Technical field
The utility model relates to underground construction equipment, relates in particular to the motion feed arrangement 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, and this just need send into devices such as milling pin rod in the middle of the dell, and the side direction underground tank often has certain vertical depth requirement, only adopts crane rope can't satisfy the depth accuracy requirement.
Summary of the invention
The utility model is intended to solve the above-mentioned defective of prior art, and a kind of feeding device of underground lateral trenching and milling device is provided.The utility model is simple in structure, can make accurately the underground lateral trough forming system is fed into certain height and then finishes grooving work.
The utility model is achieved in that
A kind of feeding device of underground lateral trenching and milling device, it is in order to send to certain depth to the side direction trough forming system, described side direction trough forming system mainly comprises and mills pin assembly and control valve thereof on a saddle, the saddle, it mainly comprises: a feed cylinder, there is the footstock that is connected with wire rope its upper end, and its piston-rod lower end is provided with the ear seat that is fixed on the saddle.
Described feeding device of underground lateral trenching and milling device, it also comprises a stroke sensing device, described stroke sensing device comprises a tablet that is positioned at the sensor of feed cylinder cylinder body upper end and is positioned at the cylinder body lower end, and sensor and tablet are positioned on the straight line.
Described feeding device of underground lateral trenching and milling device, the footstock of described feed cylinder comprises a flat board, this flat board top is provided with a pair of otic placode that has earhole that is oppositely arranged, and is provided with horizontal bearing pin therebetween in order to connect wire rope.
Described feeding device of underground lateral trenching and milling device, described ear seat bottom has a flat board that is welded to connect saddle.
The flexible saddle that drives of feed cylinder piston rod of the present utility model moves up and down, and then influence the milling behavior of milling bar on the saddle, when piston rod is stretched, by the amount of feeding of control valve control to set, rotation milling bar is just realized quantitatively cutting, cause mixing of mud and pulp-water, realize mud circulation then; Stretch when sufficient when piston rod, stroke sensor can provide a signal, and piston rod shrinks with fast speed then, transfers corresponding length wire rope again after being retracted to the end, and above process repeats, thereby finishes side direction grooving work accurately, quickly and smoothly.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2: a kind of feeding device of underground lateral trenching and milling device, it is in order to send to certain depth to the side direction trough forming system, described side direction trough forming system mainly comprises and mills pin assembly and control valve thereof (failing among the figure to show) on a saddle, the saddle, it mainly comprises: a feed cylinder 1, there is the footstock 2 that is connected with wire rope its upper end, and its piston-rod lower end is provided with the ear seat 3 that is fixed on the saddle.
It also comprises a stroke sensing device, and described stroke sensing device comprises a tablet 5 that is positioned at the sensor 4 of feed cylinder 1 cylinder body upper end and is positioned at the cylinder body lower end, and sensor 4 and tablet 5 are positioned on the straight line.
The footstock of feed cylinder 1 comprises a flat board, and this flat board top is provided with a pair of otic placode that has earhole that is oppositely arranged, and is provided with horizontal bearing pin therebetween in order to connect wire rope.Described ear seat 3 bottoms have a flat board (failing among the figure to show) that is welded to connect saddle.
