Abstract
The utility model belongs to punching equipment for extracting coal mine gas in a coal mine under ground, in particular to a wide range lifting deep hole drilling rig for mining. The drilling rig solves the technical problem that the punching height of the existing drilling rig can not achieve the requirement for effectively extracting the coal mine gas during the extraction process of the gas of a mine with large amount of gas. The drilling rig structurally comprises a walking portion, a vertical prop and a lifting support are arranged on the walking portion, a host machine is movably installed on the prop, and a lifting arm is arranged on the lifting support and connected with the host machine. The walking portion further is provided with a hydraulic system and a control system which control the lifting support. The drilling rig realizes the vertical and extensible movement by supplying oil through a hydraulic pump, then leads the lifting arm arranged on a lifting mechanism to move vertically, and finally leads the host machine to be lifted vertically. The drilling rig can meet the technical requirements for multi-layer hole drilling at a position 1.2m to 4.0m under ground and intensively extracting the gas, solves the production problem of coal mine with the large amount of the gas, guarantees smooth production of mining, and meets the requirement that the host machine works at different height in a under ground tunnel.
Description
Technical requirements
The utility model belongs to the punch device of underground mine use in gas discharge in mine, is specially a kind of ascending/decending on a large scale colliery deep hole drill car.
Background technology
The present drill carriage (or rig) produced of domestic and international several families drill carriages (or rig) manufacturer, the drill center height is lower, generally the highlyest is no more than 2 meters, all is individual layer boring, can't realize layering boring.The technological requirement that satisfies that the coal seam is thick, gas permeability is poor, draws out methane under the high special geologic condition of gas bearing capacity is only beaten the intensive extraction of multilayer hole at distance ground differing heights, could draw out methane effectively, and the drill center height that has need reach about four meters.Obviously present machine on the market can't satisfy the requirement of this mine.And for highly gassy mine, if gas can not get effective extraction, coal mining just can't carry out smoothly, and this not only can bring enormous economic loss, exists serious potential safety hazard simultaneously.
Summary of the invention
The purpose of this utility model is in order to solve existing drill carriage punching in the highly gassy mine gas drainage under suction process highly not to be reached the standard techniques problem of effective extraction and a kind of ascending/decending on a large scale colliery deep hole drill car is provided.
The utility model is realized by following technical scheme, a kind of ascending/decending on a large scale colliery deep hole drill car, structure comprises running part, on running part, be provided with column, crane, be movably installed with main frame on the column, crane is provided with lifting arm, and lifting arm connects main frame, also is provided with the hydraulic system and the control system of control crane on the running part.
The utility model is by being realized hydraulic jack stretching motion up and down by the hydraulic pump fuel feeding, the boom that rises that drives then on the elevating mechanism also moves up and down, and drives the main frame oscilaltion at last.Can satisfy at 1.2-4.0 rice and beat perforated, the intensive technological requirement that draws out methane, solve the production difficult problem of highly gassy mine, the guarantee mine is produced smoothly.Realize the requirement of main frame differing heights work in the tunnel.
Compared with prior art, the utility model adds elevating mechanism in main frame one side, and elevating mechanism is fixed on the drill carriage travelling platform, and main frame is fixed by the front and back column, and elevating mechanism is flexible up and down under hydraulic cylinder control, thereby realizes rising, the decline of main frame.The highest 2.8m that raises of elevating mechanism, the drill center altitude range of main frame can reach 1.2m-4.0m, thereby realizes the multilayer multistation boring in the 1.2m-4.0m scope.The boring needs that adapt to high seam, low-permeable, highly gassy mine.When needing to beat perforated, the operation hydraulic system rises to main frame easily by lifting arm and requires the position, can realize that the multilayer multistation drills, and that drill carriage does not need to do is any mobile.
Description of drawings
Fig. 1 is the utility model colliery deep hole drill car unitary construction figure.
Fig. 2 is colliery described in the utility model with deep hole drill car vertical view (not containing hydraulic system and operating system).
Among the figure: 1-main frame, 2-column, 3-crane, 4-hydraulic system, 5-control system, 6-running part, 7-travelling platform, 8-lifting arm.
The specific embodiment:
As schematically shown in Figure 1, 2, a kind of ascending/decending on a large scale colliery deep hole drill car, structure comprises running part 6, be movably installed with main frame 1 being provided with on the running part 6 on column 2, crane 3, the column 2, crane 3 is provided with lifting arm 8, lifting arm 8 connects main frame, also is provided with the hydraulic system 4 and the control system 5 of control crane on the running part 6.
Dispose hydraulic jack on the crane 3, the piston rod of hydraulic jack connects lifting arm 8, and oil cylinder carries out lifting by hydraulic pump drive, and oil cylinder is flexible up and down, drives lifting arm and moves up and down, and has realized the oscilaltion of main frame simultaneously.When main frame is raised to bore position, still fix by the slips on the column of front and back, play firm effect.
Described column 2 is a more piece combined type adjustable height type structural column, between the more piece column for being threaded.Main frame relies on four root posts location, and every root post structure is detachable combined type, increases or reduce according to differing heights to add long column quantity on every root post, reduces the static height of complete machine; Crane is the two grade of ascend and descend frame, has both satisfied the requirement of lifting altitude, makes the oneself height of the lifting altitude of elevating mechanism greater than itself again, and is comprehensive, can realize that main frame satisfies the requirement of using in the lifting of 1.2-4.0 rice in the tunnel.
