Abstract
The invention discloses a pulley fulcrum capable of achieving two-dimensional deflection and belongs to the field of withdrawal machine pulley supports. The technical problems that the position of an existing pulley support cannot be adjusted, and the application range is narrow are solved. According to the technical scheme, the pulley fulcrum comprises a frame withdrawal table and a pulley support. A pulley is arranged in the pulley support. The frame withdrawal table and the pulley support are connected through a plurality of horizontal telescopic oil cylinders. The fixed ends of the telescopic oil cylinders are fixedly connected with the frame withdrawal table. The movable ends of the telescopic oil cylinders are fixedly connected with the pulley support. A plurality of supporting oil cylinders are arranged between the bottom of the pulley support and the frame withdrawal table. The fixed ends of the supporting oil cylinders are hinged to the frame withdrawal table. The movable ends of the supporting oil cylinders are hinged to the pulley support. The telescopic oil cylinders and the supporting oil cylinders are all communicated with a control system through hydraulic pipelines.
Description
Technical field
The invention belongs to and withdraw from machine pulley bracket field, particularly relate to a kind of can bidimensional displacement pulley fulcrum.
Background technology
Remove on machine at the hydraulic support in carrier and field, colliery and all can use fixed pulley, fixed pulley is all generally be fixed on specific support, meet the effect that fixed pulley changes the direction of power, but the existing hydraulic support fixed pulley removed on machine is installed on fixed support, the position of fixed pulley support is unadjustable, Applicable scope is narrow, uses very inconvenient, can not adapt to different height.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, solve existing pulley bracket position unadjustable, the problem that applicable area is narrow, aim to provide a kind of can bidimensional displacement pulley fulcrum, this pulley bracket structure is simple, and use, by the flexible position adjusting pulley bracket of telescopic oil cylinder, thus make fixed pulley be in different positions, increase the range of use of machine of withdrawing from.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: can bidimensional displacement pulley fulcrum, comprise and remove pallet and pulley bracket, pulley is provided with in pulley bracket, remove between pallet and pulley bracket and connected by multiple horizontally disposed telescopic oil cylinder, the fixed end of telescopic oil cylinder with remove pallet and be fixedly connected with, the movable end of telescopic oil cylinder is fixedly connected with between pulley bracket, the bottom of pulley bracket and remove between pallet and be tiltedly installed with multiple support cylinder, the fixed end of support cylinder with remove pallet and be articulated and connected, movable end and the pulley bracket of support cylinder are articulated and connected, described multiple telescopic oil cylinder is all communicated with control system by hydraulic tubing with multiple support cylinder.
Preferably, pulley bracket comprises rest body, and described rest body entirety is quadra structure, and the middle part of rest body is pulley installation region, the left end of rest body is preset with the mounting hole be connected with telescopic oil cylinder, and the lower end of rest body is preset with the hinged seat be connected with support cylinder.
Preferably, described pulley is connected with pulley bracket by adapter shaft, and the two ends of adapter shaft are all connected with captive nut through the sidewall of rest body.
Preferably, the quantity of described telescopic oil cylinder is four, and the quantity of support cylinder is two.
The present invention compared with prior art has following beneficial effect: the present invention is by arranging multiple telescopic oil cylinder removing between platform and pulley bracket, according to the distance of removing between platform and hydraulic support, control system is utilized to adjust the collapsing length of telescopic oil cylinder, thus between change pulley with the distance of hydraulic support, enable to remove platform to work in different positions, increase and remove platform range of use, promote and remove efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of rest body.
In figure: 1 for removing pallet, 2 is pulley bracket, and 21 is rest body, and 22 is mounting hole, and 23 is hinged seat, and 3 is telescopic oil cylinder, and 4 is support cylinder, and 5 is pulley, and 6 is adapter shaft, and 7 is captive nut.
Detailed description of the invention
As Figure 1-Figure 2, can bidimensional displacement pulley fulcrum, comprise and remove pallet 1 and pulley bracket 2, pulley 5 is connected with pulley bracket 2 by adapter shaft 6, the two ends of adapter shaft 6 are all connected with captive nut 7 through the sidewall of rest body 21, remove between pallet 1 and pulley bracket 2 and connected by multiple horizontally disposed telescopic oil cylinder 3, the fixed end of telescopic oil cylinder 3 with remove pallet 1 and be fixedly connected with, the movable end of telescopic oil cylinder 3 is fixedly connected with between pulley bracket 2, the bottom of pulley bracket 2 and remove between pallet 1 and be tiltedly installed with multiple support cylinder 4, the fixed end of support cylinder 4 with remove pallet 1 and be articulated and connected, movable end and the pulley bracket 2 of support cylinder 4 are articulated and connected, described multiple telescopic oil cylinder 3 is all communicated with control system by hydraulic tubing with multiple support cylinder 4.
As shown in Figure 3, particularly, pulley bracket 2 comprises rest body 21, described rest body 21 entirety is quadra structure, the middle part of rest body 21 is pulley 5 installation region, the left end of rest body 21 is preset with the mounting hole 22 be connected with telescopic oil cylinder 3, and the lower end of rest body 21 is preset with the hinged seat 23 be connected with support cylinder 4.
