Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further details:
As it is shown in figure 1, a kind of colliery roadway repairer, including body part and actuator, described body part includes running gear 7 and is arranged on the vehicle frame 6 above running gear 7.Pilot set, operating board are installed on vehicle frame 6, the electromotor etc. of power is provided for running gear 7 and hydraulic jack.Described actuator includes that large arm 3, forearm 2 and scraper bowl 1, large arm 3 one end 5 are arranged on vehicle frame 6 front end, and large arm 3 is connected with one end of forearm 2 away from one end of vehicle frame 6, and forearm 2 is provided with scraper bowl 1 away from one end of large arm 3.Large arm 3 is arranged above driving the hydraulic jack of forearm 2 motion, is provided with the hydraulic jack driving large arm 3 motion below large arm 3.
Large arm and central frame beam are provided with an elevating mechanism 5, and described elevating mechanism 5 includes two guide rail 5-1 being vertically installed at vehicle frame 6 front end, and two guide rail 5-1 are each provided with the U-type groove of a vertical direction, and the U-type groove opening direction of two guide rail 5-1 is relative.Elevating mechanism 5 also includes a slide block 5-2, described slide block 5-2 coordinates with the U-type groove on guide rail 5-1 by being arranged on the gib block 5-3 of two vertical directions on slide block 5-2 side, groove is had in order to store lubricating oil, it is ensured that the lubrication between guide rail 5-1 and gib block 5-3 on U-type groove inwall on guide rail 5-1.Described slide block 5-2 is connected with vehicle frame 6 by a vertically-mounted hydraulic jack, is moved along guide rail 5-1 vertical direction by the telescopic band movable slider 5-2 of hydraulic jack.On slide block 5-2, the side away from guide rail 5-1 is hinged with large arm 3 by an intermediary agency.
Described intermediary agency is the yaw 5-4 that a yaw 5-4 or is provided with angling cylinder 4, described yaw 5-4 is vertically installed at the slide block 5-2 hinge away from gib block 5-3 side on slide block 5-2 by one, described yaw 5-4 both sides are connected with slide block 5-2 both sides by a hydraulic jack respectively, by stretching of the hydraulic jack of setting and yaw 5-4 both sides, yaw 5-4 can swing around bearing pin.On yaw 5-4, the side away from bearing pin can be by the hinged large arm of large arm mounting seat 9 or installation angling cylinder 4.When installing angling cylinder 4, being fixedly mounted on yaw 5-4 the side away from bearing pin by a flange bottom angling cylinder 4, described angling cylinder 4 is hinged with large arm 3 by the large arm mounting seat 9 being fixedly mounted on its output shaft.
When the corner for coal mine roadway belt-conveying motor spindle one class carries out operation, first with elevating mechanism 5, the axis of operation of actuator is reduced to apart from ground lowest part, then recycling angling cylinder 4 drives actuator to rotate, till actuator can enter smoothly and carry out drawing bottom belt and dig action.When running into some region actuator and cannot enter smoothly, it is also possible to utilize yaw 5-4 to swing and drive actuator to carry out angle adjustment, so that scraper bowl 1 or quartering hammer can enter operating area smoothly.
The outside of two guide rail 5-1 of elevating mechanism 5 is connected by bearing pin respectively has positioning piece 5-5, described slide block 5-2 both sides to be respectively arranged with an otic placode 5-6 matched with keeper 5-5.Keeper 5-5 can swing forward or backward around bearing pin, a chuck it is provided with bottom otic placode 5-6, when slide block 5-2 rises to highest point under the drive of hydraulic jack, keeper 5-5 can be rocked to below otic placode 5-6, contact with the chuck on otic placode 5-6, thus slide block 5-2 vertical direction is played certain supporting role, prevent hydraulic jack to lose efficacy to fall suddenly with rear slider 5-2.It is in most cases to carry out routine work when slide block 5-2 is in highest point in view of this utility model, thus a chuck only it is provided with in otic placode 5-6 bottom, but when roadway repairer needs to allow slide block 5-2 in an intermediate position for a long time or extreme lower position carries out routine work when, multiple chuck need to be set on otic placode 5-6, thus keeper 5-5 can be played a supporting role the arbitrary height of slide block 5-2.
On described forearm 2, the one end away from large arm 3 is connected with scraper bowl 1 by a fast replacing device 8, described fast replacing device 8 includes a riser 8-1 being provided with C-shaped channel I, connected by bearing pin on described riser 8-1 and have claw 8-2, the C-shaped channel II contrary with C-shaped channel I opening direction it is provided with on claw 8-2, described claw 8-2 is connected by one end of bearing pin and a hydraulic jack, the other end of described hydraulic jack is connected with riser 8-1, and described riser 8-1 is provided with suspension hook 8-3.This fast replacing device 8 includes that two riser 8-1 being symmetrically installed along car body axis add the structure of claw 8-2, a transverse axis is used to be fixed between two claw 8-2, one end of hydraulic jack carries out hinged with the cross bar being connected claw 8-2, and between two symmetrical riser 8-1, same employing cross bar is fixed and is arranged on forearm 2.Accordingly, two cross bars for matching it are equipped with two C-shaped channel on scraper bowl 1 and quartering hammer, fast replacing device 8 drives claw 8-2 to swing up and down around bearing pin by hydraulic jack, when being rocked to lower section, claw 8-2 unclamps the cross bar on scraper bowl 1, now can change scraper bowl 1 or quartering hammer, when claw 8-2 be rocked to top time two C-shaped channel clamping scraper bowls 1 on two cross bars thus fix scraper bowl 1 or quartering hammer.Find in actual applications, use due to devices such as the yaw in this utility model, elevating mechanism, angling cylinders, the position of fast replacing device and angle can arbitrarily adjust, so that fast replacing device is more convenient when changing scraper bowl or quartering hammer, it is only necessary to a small amount of human assistance just can complete Renewal process.
