Abstract
The utility model relates to an advance supporting device of drivage face, pertaining to the temporary top board control device before the laneway permanent support. The top of the device is at least provided with two hinging beams which are mutually hinged to form an integer; a hydraulic pressure strut is positioned at the middle part of the device, and the upper part of the device is fixedly connected with the hinging beams and the lower part is fixedly connected with a tunneling walking device. The device has the aim of duly controlling the top board after the explosion operation so as to protect the constructor, and also has the function of protecting the device and other apparatuses during the blast process. Using the device can reduce the empty top time and duly support the laneway top board so as to effectively guarantee the safety of the operation staff at the work face. The utilization of the device can change the construction art during the tunneling operation process, quicken the tunneling speed, and improve the safety factor of the tunneling work so as to prevent the top board accident from happening.
Description
Technical field
The utility model relates to a kind of to the provisional Roof Control device before the permanent support of tunnel, specifically is applicable to advanced stand device of driving face in mine working and the railway tunnel construction process.
Background technology:
The facility of lame advanced supporting only is a mode of using forestope in the both sides, tunnel at present, and this device can not carry out supporting and just play the effect of blocking in both sides the tunnel, so the inbreak in tunnel still personnel casualty accidents can occur.The driving face roof accident is that the most frequent accident takes place mine industry, and all cause a large amount of casualtiess every year, therefore, takes technical measures and device targetedly, the generation of stopping accident, and reducing casualties is problem demanding prompt solution.
Summary of the invention:
The technical problems to be solved in the utility model is the defective at prior art, and a kind of top time that reduces to control in the tunnelling process is provided, and immediate support exposes top board, the advanced stand device of driving face of protection operating personnel's safety under the tunnel.
Solve the problems of the technologies described above by the following technical solutions: a kind of advanced stand device of driving face, its structural feature be, the top of described device is provided with two hinged girders at least, and being hinged between hinged girder and the hinged girder is integral; Hydraulic prop is positioned at the middle part of device, fixedlys connected with hinged girder in its top, and the bottom is fixedly connected on the driving running gear.
Owing to adopted technique scheme, compared with prior art, this device possesses in time controls top board after bursting work, and protection constructor's purpose also possesses simultaneously in the protective effect of banger process to this device and other equipment.Use this device can reduce the empty top time, in time back is carried out supporting, guarantee work plane operating personnel's safety effectively.And this device is installed on the running gears such as development machine, random motion advances, do not need artificial moving, promptly save manpower and can change construction technology in the excavation operation process again, not only accelerated driving speed, also improve the safety factor of headwork, can contain the generation of roof accident effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that fully mechanized workface uses advance support schematic diagram of the present utility model.
Fig. 3 is that gun diging face uses the utility model advance support schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to accompanying drawing 1, this device is made up of hinged girder, hydraulic prop 4 and running gear 5 etc., the quantity of hinged girder is set according to the purposes of device, article at least two, hinged girder is arranged on the top of device, it is in aggregates to be hinged between hinged girder and the hinged girder, hydraulic prop 4 is positioned at the middle part of device, fixedlys connected with hinged girder in its top, and the bottom is fixedly connected on the driving running gear 5.
This device is divided in the tunnel or tunnel adopts advanced stand device that adopts under the bursting work situation and the advanced stand device that adopts under the situation of tunnel or tunnel employing mechanical work.
Fig. 2 is that fully mechanized workface uses advance support schematic diagram of the present utility model, and its driving running gear is a development machine 8.Referring to accompanying drawing 2, the top of this device is provided with three hinged girders 1,2,3, and the middle part is a hydraulic prop 4, and the bottom is a development machine 8.Hinged girder 1, hinged girder 2 and hinged girder 3 are hinged into an integral body, be positioned at the top of device, hydraulic prop 4 is positioned at the middle part of device, weld mutually with hinged girder the upper end of hydraulic prop 4, the bottom is connected with base for supporting 7, and by base for supporting 7 that hydraulic prop 4 is fixing and be connected on the telescopic arm of development machine 8, by development machine 8 walkings.Development machine 8 is walked on base plate 9, when development machine 8 coal cuttings after hours, the work crown of development machine 8 is to 10 li of ribs, and telescopic arm is set level, and adopts hydraulic pressure that hydraulic prop 4 is risen, and drives the hinged girder action, supporting roof 6.This device is little to the transformation of the way amount of development machine, does not interfere motion, cut, the loading operation function of development machine.
Fig. 3 is that gun diging face uses the utility model advance support schematic diagram.Referring to accompanying drawing 3, the top of this device is provided with two hinged girders 1,2, article two, hinged girder 1,2 is hinged, and the middle part is a hydraulic prop 4, the upper end of hydraulic prop 4 and hinged girder welding, bottom and base car 11 weld together, and base car 11 is by moving wheel 12 walking on base plate 9.After explosion finishes, this device is pushed into driving face, adopts hydraulic pressure that hydraulic prop 4 is risen, drive the hinged girder supporting roof at top.
The utility model is to prop up, to protect and take into account, and it is big that it protects top area, and support speed is fast, and is safe and effective.
