Description
Technical field
The utility model relates to the tight rope device that uses in a kind of mine rail transport systems, a kind of specifically dynamic boomer.
Background technology
In recent years, the China's coal-mine production technique has been obtained large development, along with the continuous expansion of pit mining scale and the continuous extension of down-hole developing distance, the haul distance of rope traction Orbital Transport Systems is also more and more longer, under coal mine, in the rope traction Orbital Transport Systems, generally be provided with steel wire rope stretching device, for the Orbital Transport Systems of long haul distance at the winch end, tensioning to system's steel rope has higher requirement, particularly tight rope amount and tight rope speed is had higher requirement.If the tight rope amount can cause the steel rope can't tensioning inadequately, system can't move; The tight rope amount is crossed and may well be caused steel rope to break, and causes safety misadventure; Tight rope speed is slow excessively, the untimely meeting of tight rope causes vehicle to occur skidding, and the safety that influence is produced is carried out.
At present, the tensioning of cableway steel rope generally has three types of hydraulic pressure, indirect labor and winch formulas.Indirect labor's tensioning and the tensioning of winch formula are to adopt chain block or a section tensioning of winch, be fixed to again on the automatic weighing hook, and the tensioning on period, cableway must quit work, and labour intensity is big, influences normal manufacturing schedule.The fluid pressure type clamping system comprises Hydraulic Pump and various control element, and need set up hydraulic oil unit, and the control convenience complexity is invested bigger.
The utility model content
The utility model technical issues that need to address provide a kind of simple in structure, dynamic boomer easily and fast.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
Dynamic boomer, comprise support body, the bottom of support body is set with at least two fixed pulleys by support, a movable pulley is set between the adjacent fixed pulley, also be provided with the slideway that supplies movable pulley in support body, to slide up and down between adjacent fixed pulley on the described support body, the top of described slideway is provided with center shaft and the perpendicular track adjusting wheel I of movable pulley anchor shaft, is surrounded with on the track adjusting wheel I to be connected the heavy burden stay cord that the other end connects clump weight on an end and the movable pulley anchor shaft; Described system steel rope is looped around on the race of the fixed pulley that is provided with at interval and movable pulley successively.
Further improvement of the utility model is: described slideway is vertical with support to be provided with.
Further improvement of the utility model is: the two ends of described support body are provided for the track adjusting wheel II of designating system steel rope trend respectively.
Further improvement of the utility model is: be provided with straight down pilot bar with corresponding position, the track adjusting wheel I outside on the described support body back timber, described clump weight slip cap is connected on the pilot bar.
Because the technological advance that has adopted technique scheme, the utility model to obtain is:
The utility model is simple in structure, has satisfied when growing haul distance in the rope traction Orbital Transport Systems under the coal mine the slack-free requirement of steel rope.In the rail transport process, dynamically boomer can be according to the running condition automatically regulating amount of tension of steel rope, and along with different change dynamics adjustment, appersonation.
Slideway is vertical with support when being provided with, and boomer is the sensitiveest when adjusting, and the design of track adjusting wheel I not only can be used to change the direction of heavy burden stay cord, and the wearing and tearing of the stay cord that can also prevent to bear a heavy burden increase the service life.The track adjusting wheel II is used for the trend of stabilization system steel rope, is connected closely when making the fixed pulley of system's steel rope in walking around boomer, prevents steel rope abrasion, increases the service life.Pilot bar can be controlled the direction of clump weight, prevents that clump weight from waving in the process that rises or descend, and influences the dynamicsensitivity of boomer, guarantees that boomer can normally move with optimum regime.

Wherein, 1, support body, 2, the track adjusting wheel I, 3, pilot bar, 4, movable pulley, 5, the heavy burden stay cord, 6, clump weight, 7, fixed pulley, 8, slideway, 9, the track adjusting wheel II, 10, system's steel rope.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details:
Dynamic boomer, structure comprises support body 1 as shown in Figure 1 and Figure 2, be provided with horizontally disposed support and vertically disposed slideway 8 in the support body 1, fixedly install at least two fixed pulleys 7 on the support, be provided with movable pulley 4 in the slideway 8, movable pulley 4 can slide up and down in support body 1 along slideway 8.Spare on the support in the present embodiment and be furnished with 7, three movable pulleys 4 of four fixed pulleys and three slideways 8.
As shown in Figure 1, be set with track adjusting wheel I 2 on support body 1 back timber on slideway 8 tops, the anchor shaft of the center shaft of track adjusting wheel I 2 and movable pulley 4 is perpendicular, is surrounded with heavy burden stay cord 5 on the track adjusting wheel I.One end of heavy burden stay cord 5 is captiveed joint with the anchor shaft of movable pulley 4, and the other end of heavy burden stay cord 5 connects a clump weight 6.As shown in Figure 2, in the upper surface of support body 1, be provided with a connecting panel below the track adjusting wheel I 2, be provided with pilot bar 3 straight down in the lower surface of connecting panel, be provided with the hole that cooperates with pilot bar 3 external diameters in the described clump weight 6, clump weight 6 can slide up and down along pilot bar 3.
As shown in Figure 1, end face is provided with track adjusting wheel II 9 respectively in the left and right sides of support body 1, behind track adjusting wheel II 9 change of directions of system's steel rope 10 in the Orbital Transport Systems by end setting, on fixed pulley 7 races of outermost end to dynamic boomer, be looped around on the race of movable pulley 4 and fixed pulley 7 afterwards in order successively, stretch out dynamic boomer from support body 1 other end at last, get back in the Orbital Transport Systems by the track adjusting wheel II 9 that is arranged on the other end again.
Operational process of the present utility model is:
In the utility model, heavy burden stay cord 5 one ends are connected on the anchor shaft of movable pulley 4, the other end is connected with clump weight 6 after track adjusting wheel I 2 guiding, and the anchor shaft of movable pulley 4 is complied with slideway 8 under the effect of clump weight direction moves up and down, and clump weight 6 moves up and down along pilot bar 3.
When becoming flexible appears in system's steel rope 10, clump weight 6 moves downward at the effect lower edge pilot bar 3 of deadweight, drive movable pulley 4 upwards motion in slideway 8 by heavy burden stay cord 5, interval between movable pulley 4 and the fixed pulley 7 increases, the movable pulley 4 and system's steel rope 10 length on the fixed pulley 7 that are looped around this moment in the boomer increase, system's steel rope 10 length that are used for Orbital Transport Systems are shortened, system's steel rope 10 tensioning rapidly.
When system's steel rope 10 stressed excessive when tight, under the tension of system's steel rope 10, movable pulley 4 moves downward along slideway 8, heavy burden stay cord 5 traction clump weights 6 are along pilot bar 3 upward movements, distance between movable pulley 4 and the fixed pulley 7 shortens at this moment, then system's steel rope 10 length in the boomer reduce, and system's steel rope 10 length that are used for Orbital Transport Systems increase, and system's steel rope 10 can be adjusted to suitable tensioning state.By such process, the continuous automatic compensation of boomer guarantees steadily operation smoothly of Orbital Transport Systems.
