Description
Technical field
The utility model relates to a kind of bolt clamp device, particularly relates to the horizontal iron bolt fastener of a kind of coke oven door.
Background technology
The outside of coke oven masonry is all provided with furnace retaining equipment; its effect is the potential energy utilizing adjustable springs; continuously to masonry apply enough, be evenly distributed rational protectiveness pressure, makes masonry self expand and still can keep complete, tight under External Force Acting, thus the normal production of guarantee coke oven.Firedoor frame is the important component part in furnace retaining equipment, is used for fixing fire door simultaneously, and fire door will hold out against by horizontal iron bolt, after pressurization, the horizontal iron of fire door bears very large pressure, and not only labour intensity is large to use manpower to complete fastening bolt operation, and efficiency is low, have impact on construction speed.
Summary of the invention
The utility model provides the horizontal iron bolt fastener of a kind of coke oven door, utilizes the pulling force of outside crane to realize the fastening of the horizontal iron bolt of pressurization coke oven door, increases work efficiency, reduce labor strength.
In order to achieve the above object, the utility model realizes by the following technical solutions:
The horizontal iron bolt fastener of a kind of coke oven door, comprise rotating disk, limited block and steel wire rope, described center of turntable offers the hexagon through hole that the horizontal iron bolt with coke oven door adapts, limited block is established in through hole one end, cannelure is offered in disk peripheral direction, establish lacing hole near the inner side of cannelure, steel wire rope one end is fixed in lacing hole, and the other end is connected with the suspension hook of outside crane after cannelure several weeks.
Between described hexagon through hole and horizontal iron bolt, one-sided gap is 0.5 ~ 1mm, rotating disk width 5 ~ 10mm less of bolt head thickness.
Compared with prior art, the beneficial effects of the utility model are:
1) utilize the pulling force of outside crane to realize the fastening of the horizontal iron bolt of pressurization coke oven door, increase work efficiency, greatly reduce labor strength;
2) structure is simple, easy to make, can change the rotating disk adapted according to the different type of furnace;
3) size of fastening force is adjusted according to the gap between the horizontal iron outer face of fire door and bolt head outer face, simply controlled.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1, it is structural representation of the present utility model, the horizontal iron bolt fastener of a kind of coke oven door of the utility model, comprise rotating disk 2, limited block 4 and steel wire rope 6, the hexagon through hole that horizontal iron bolt 3 adapts with coke oven door is offered at described rotating disk 2 center, and limited block 4 is established in through hole one end, rotating disk 2 circumferencial direction offers cannelure 7, establish lacing hole 5 near the inner side of cannelure 7, steel wire rope 6 one end is fixed in lacing hole 5, and the other end is connected with the suspension hook 8 of outside crane after cannelure 7 several weeks.
One-sided gap 0.5-1mm between described hexagon through hole and horizontal iron bolt 3, rotating disk 2 width 5-10mm less of bolt head thickness.
Due to the particularity of coke oven door structure, when the horizontal iron bolt of fire door 3 is fastening, pressure is comparatively large, uses traditional torque spanner with manually carrying out fastening wasting time and energy.The utility model utilizes mechanical tensile forces and the lever principle of crane, this process is simplified, and not only can improve operating efficiency, also greatly reduces the labour intensity of workman.
The horizontal iron bolt fastener of a kind of coke oven door of the utility model, first according to the diameter of the space around horizontal iron bolt 3 and required moment size determination rotating disk 2, does not need strictly to calculate, rule of thumb determines.Offer the hexagon through hole adapted with required fastening horizontal iron bolt 3 at rotating disk 2 center, and between horizontal iron bolt 3, one-sided gap is 0.5 ~ 1mm, makes it to be enclosed within bolt smoothly; Limited block 4 is fixed in hexagon through hole one end, and the width of limited block 4 is less than the maximum gauge of horizontal iron bolt 3, so that the position of the horizontal iron bolt 3 of direct vision, and convenient operation.Width 5 ~ the 10mm less of bolt head thickness of rotating disk 2, does not hinder horizontal iron bolt 3 to be close to horizontal iron 1.
Rotating disk 2 circumferencial direction offers annular notches 7, and inside it, section configuration is semicircle, and adapt with steel wire rope 6, its degree of depth should meet the winding number of turns of steel wire rope 6.Offer a manhole at rotating disk 2 near the inner side of cannelure 7, for passing and fixing steel wire rope 6, steel wire rope 6 one end is fixed in lacing hole 5, and the other end is wrapped in cannelure 7 and is connected with the suspension hook 8 of crane after a few.
During use, horizontal iron bolt 3 after only the hexagon through-hole alignment at rotating disk 2 center need being twisted in advance puts clamping, being fixed by steel wire rope 6 and winding the rear other end hangs on the suspension hook 8 of crane, start the slow lifting hook 8 of crane, drive steel wire rope 6 that rotating disk 2 is rotated, thus by fastening for the horizontal iron bolt 3 at center.Whether determine that horizontal iron bolt 3 is fastening according to the gap of the fire door of drawing requirement horizontal iron 1 end face and bolt head end face to put in place, after reaching requirement, crane stops, and is unloaded by rotating disk 2 from horizontal iron bolt 3.
Make corresponding rotating disk 2 according to horizontal iron bolt 3 specification, select the steel wire rope 6 of suitable length when operation, the installation requirement of the horizontal iron 1 of different model coke oven door can be met.
