Description
Technical field
Compression leg jack lifter device of the present invention, belong under the coal mine winch, scratch board conveyor etc. fixedly supporting use the mechanical lifting gear technical field.
Background technology
The winch that mining face under mine and tunnel are used generally adopts concrete foundation to fix, and roving winch or jury winch generally adopt fixedly supporting of round log, because the length of round log is certain; Winch is under the situation that does not receive tractive force; Round log setting load between top board and the winch is very little, adds the not sclerosis of some back, and coal body is softer; Winch possibly be inserted in the top board coal body at round log under the effect of heavy load tractive force and go; Winch produces displacement makes round log lose fixedly support action, the whole supporting of winch was lost efficacy, even cause the generation of shipping accident; Scratch board conveyor belongs to roving plant equipment; So generally adopting round log to make compression leg fixes head, tail; Same length owing to round log is fixed; Do not have enough big setting load, add scratch board conveyor the time be in vibrational state always in work, thus adopt separately round log fixedly supporting effect be not fine.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved provides small and exquisite, easy to use safe, the fixed compression leg jack lifter device of a kind of structure.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: compression leg jack lifter device, comprise end boots, end boots sleeve, jack, round log Connection Block and round log cap bag, and the structure of end boots is: cylinder vertically is fixed on the base plate top; End boots sleeve is cylindric; End boots sleeve set is outside cylinder, and boots sleeve lower end, the end contacts with base plate, and the upper end of end boots sleeve is welded on below the jack; The upper end of jack is equipped with the round log Connection Block, and the round log cap bag vertically is positioned at the top of round log Connection Block.
Cylinder in the boots of the said end and end boots sleeve are fastening fixing through circular pegs.
Parallel welding in the top of described round log cap bag or straight line are welded with the anti-slop serrations of two inverted triangle shapes.
The sidewall of said round log Connection Block and round log cap bag all has screwed hole, all is connected with a bolt in each screwed hole.
Described base plate is inverted groove shape, or below square plate, evenly is provided with a plurality of feets, or below circular slab, is provided with a plurality of feets.
The present invention compares with prior art has following beneficial effect.
1, the present invention has adopted jack and the round log Connection Block that is connected with round log, round log cap bag, and the up-down that just can accomplish round log is pressed in the arm of force hole that only needs to insert jack one side with iron rod repeatedly, and structure is small and exquisite, and is easy to use, also provides cost savings.
2, end boots among the present invention or be inverted groove shape or be provided with a plurality of feets are welded with anti-slop serrations on the round log cap bag, only need on the base of scratch board conveyor that contact with end boots or winch, add rubber, prevent that contact from skidding, and safety is firm more.
3, the present invention makes round log be connected with the round log cap bag with the round log Connection Block with bolt, prevents that being connected not firm dropping with round log hurts sb.'s feelings, and safety is firm more.
4, the end of the present invention boots are connected fixing with jack with circular pegs with suit; Just can change different end boots according to the scratch board conveyor of different model or the different bases of winch; Change the jack of different tonnages according to different purposes, change and conveniently also provides cost savings.

The specific embodiment
Shown in Fig. 1-10; Compression leg jack lifter device of the present invention comprises end boots 1, end boots sleeve 2, jack 3, round log Connection Block 4 and round log cap bag 5, and the structure of end boots 1 is: cylinder 6 vertically is fixed on base plate 7 tops; End boots sleeve 2 is cylindric; End boots sleeve 2 is sleeved on outside the cylinder 6, and boots sleeve 2 lower ends, the end contact with base plate 7, and the upper end of end boots sleeve 2 is welded on below the jack 3; The upper end of jack 3 is equipped with round log Connection Block 4, and round log cap bag 5 vertically is positioned at the top of round log Connection Block 4.
Parallel welding in the top of described round log cap bag 5 or straight line are welded with the anti-slop serrations 9 of two inverted triangle shapes.
The sidewall of said round log Connection Block 4 and round log cap bag 5 all has screwed hole, all is connected with a bolt in each screwed hole.
Described base plate 7 is inverted groove shape, or below square plate, evenly is provided with a plurality of feets 8, or below circular slab, is provided with a plurality of feets 8.
The end of the present invention boots contact with the base of scratch board conveyor 12 or winch 13, and contact surface is added with rubber and skids preventing.
Two anti-slop serrations 9 of the present invention are 50mm for the length of side, and thick is the right angle triangle of 20mm.
Cap bag internal diameter of the present invention is designed to 230mm, is applicable to the log diameter of down-hole 90%.
Method for using: the end of the present invention boots are positioned on the base of scratch board conveyor 12 or winch 13, round log Connection Block 4 is put in round log 11 bottoms, again round log cap bag 5 is enclosed within round log 11 tops.
Be screwed in the round log 11 in the nut that is inserted into round log Connection Block 4 and round log cap bag 5 sidewalls with two externally threaded bolts of taper reducing band shown in figure 10 and the screwed hole and with it, round log 11 and round log Connection Block 4 or round log cap bag 5 firmly are fixed together.Because the diameter of round log 11 varies; When the diameter of round log 11 during less than the interior diameter of round log Connection Block 4 and round log cap bag 5; Not having the sidewall of screwed hole to put into timber wedge at round log Connection Block 4 and round log cap bag 5 clogs the gap between round log 11 and round log Connection Block 4 and round log cap bag 5 inwalls, has a side of screwed hole bolt to be screwed into fixing; During with round log cap bag 5 interior diameters, can round log 11 be cut carefully greater than cover round log Connection Block 4 when the diameter of round log 11, then bolt is screwed into fixing.
At last; Insert the arm of force hole of jack 3 one sides with iron rod; Press jack to regulate the distance that round log 11 goes up and down repeatedly, make round log between back and scratch board conveyor 12 or winch 13 bases receive enough setting loads its winch or scratch board conveyor are firmly fixed, like Figure 11, shown in Figure 12.
Using the go up and down range of round log 11 of the present invention is 200-300mm.
Combine accompanying drawing that embodiments of the invention have been done detailed description above, but the present invention is not limited to the foregoing description, in the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from aim of the present invention, makes various variations.
