Abstract
The utility model relates to a temporary support and top plate and bottom plate supporting device of a rock-roadway tunneling machine, which comprises a top plate supporting arm, a temporary support carrier plate, a supporting cylinder, a bottom plate supporting arm and a nailing plate. The temporary support and top plate and bottom plate supporting device is characterized in that the top plate supporting arm and the bottom plate supporting arm are respectively hinged to a fixed base of the body of the rock-roadway tunneling machine through pins, the supporting cylinder is mounted in the middle of the bottom plate supporting arm through a pin, the temporary support carrier plate is hinged to the top of the top plate supporting arm through a pin, and the nailing plate is arranged at the front end of the bottom plate supporting arm. The temporary support and top plate and bottom plate supporting device can guarantee stability and reliability in running of the rock-roadway tunneling machine and safety running rate thereof and the like, and is suitable for rock-roadway mechanical equipment for different coal mines in different size.
Description
Technical field
The utility model belongs to developing equipment technical field under the mine, is applicable to the temporary lining and the roof and floor bracing or strutting arrangement of the comprehensive mechanization stone head development machine use of rock gangway developing operation under the large, medium and small moulded coal mine.
Background technology
Developing equipment technical field under mine; One Chinese patent application numbers 200820077065.6 discloses anchor bar anchor cable rig part, hydraulic pressure and the operating system that a kind of " stone drifting and supporting construction rig " comprises track unit and belt transport section, temporary lining and the broken petrosa branch of rake rock, two liftables and swing.This equipment has three pedestals that are used for fixing oil cylinder on operating platform, wherein two pedestals are used for fixing anchor bar anchor cable rig part, and a pedestal is used for fixing temporary lining and the broken petrosa branch of rake rock.The pedestal that temporary lining and the broken petrosa of rake rock divide is in the centre of operating platform, and the pedestal of the anchor bar anchor cable rig of described two liftables and swing part is in the both sides of operating platform.Though it changes into the technical equipment of cover for realizing the construction of large, medium and small rock roadway in coal mine pick borehole, top-assisting anchor rod and anchor cable construction, broken rock rake rock, detritus transportation, temporary lining machinery; Realize safety in production for large, medium and small colliery and created the most basic condition; But------line--is blown out and--is broken rock and--harrow--mucking--temporary lining--anchor bar anchor cable supporting---whitewashing of rock fortune rock in powder charge in warning because construction technology is: perforating.Still can not break away from the traditional handicraft of the rock of drilling and blasting brokenly, still can not solve complex process, the slow stone drifting difficult problem of driving progress.
For this reason, people are devoted to research and develop the stone head development machine that uses in the stone drifting construction under the coal mine, and stone head development machine job stability and reliability are extremely important simultaneously, are directly connected to equipment operating efficiency and work safety.
Summary of the invention
The purpose of the utility model is for solving the job stability and the reliability of the stone head development machine that uses in the construction of stone drifting under the above-mentioned coal mine, and the temporary lining of the stone head development machine of a kind of high stability, reliability and the safety that provide and roof and floor bracing or strutting arrangement.
The technical scheme of the utility model is to achieve these goals:
A kind of temporary lining of stone head development machine and roof and floor bracing or strutting arrangement comprise top plate supporting arm, temporary lining supporting plate, support cylinder, backplanes support arm and nail-plate; It is characterized in that: described top plate supporting arm and backplanes support arm are hinged on respectively with bearing pin on the holder of fuselage, and support cylinder is loaded on backplanes support arm middle part with bearing pin, and hinged with bearing pin with top plate supporting arm middle front part; Described temporary lining supporting plate is hinged on the top plate supporting arm top with bearing pin; Said nail-plate is positioned at backplanes support arm front end.
A kind of temporary lining of stone head development machine and roof and floor bracing or strutting arrangement also comprise back support arm, back support cylinder; Described back support arm is hinged on the fuselage back lower place, and described back support cylinder is hinged on the fuselage back lower place and back support arm respectively.
The working stability that the utility model can guarantee stone head development machine is with reliable, and advantage such as safe operation rate.Be adapted to the rock gangway mechanical work equipment under various big, the little coal mine of neutralization.
Description of drawings
Fig. 1 is the structure chart of new temporary lining of this practicality and roof and floor bracing or strutting arrangement.
Fig. 2 is the structure partial figure of the new middle roof and floor bracing or strutting arrangement of this practicality.
The specific embodiment
The specific embodiment of carrying out the utility model below in conjunction with accompanying drawing specifies:
As depicted in figs. 1 and 2, the structure chart of a kind of temporary lining of stone head development machine and roof and floor bracing or strutting arrangement.It comprises top plate supporting arm 1, temporary lining supporting plate 4, support cylinder 2, backplanes support arm and nail-plate 3; Described top plate supporting arm and backplanes support arm are hinged on respectively with bearing pin on the holder of fuselage, and support cylinder is loaded on backplanes support arm middle part with bearing pin, and hinged with bearing pin with top plate supporting arm middle front part; Described temporary lining supporting plate is hinged on the top plate supporting arm top with bearing pin, and said nail-plate is positioned at backplanes support arm front end.
A kind of temporary lining of stone head development machine and roof and floor bracing or strutting arrangement also comprise back support arm 5, back support cylinder 6; Described back support arm is hinged on the fuselage back lower place, and described back support cylinder is hinged on the fuselage back lower place and back support arm respectively.
Promotion lower roof plate support arm at support cylinder upwards rotates, and the backplanes support arm rotates, at this moment; Top plate supporting arm and backplanes support arm make progress and open simultaneously downwards; Be used for supporting the top board and the base plate in tunnel, and the support arm 5 behind the fuselage back lower place, the fuselage with stone head development machine under the promotion of back support cylinder 6 is supported on the base plate; The effectively fixing fuselage of stone head development machine so just, and make the fuselage of whole stone head development machine in operation process, can not occur moving.
