Preferably, an annular groove matched with the outer diameter of the large rope is formed in the outer circumferential surface of the pressing wheel, so that the contact area of the pressing wheel and the large rope is increased, and slipping is avoided.
Preferably, the anti-jump rod is sleeved with a limiting sleeve for limiting the axial movement of the pressing wheel, so as to avoid the axial movement influence of the pressing wheel.
Preferably, the force application end of the compression bar is provided with a drop-proof groove for installing the chain rope, so that the large rope is pressed and fixed on the rope pulley by applying pressure on the force application end of the compression bar by the chain rope during drilling operation, and the large rope on the rope pulley is prevented from being drawn out.
As above, the utility model discloses a press rope device for dead line fixer has following beneficial effect:
the utility model has simple structure and convenient use, when the big rope needs to be coiled on the roller, only one pressure needs to be applied to the force application end of the pressure lever, so that the pressure wheel rotates by a certain angle to apply one pressure on the big rope of the rope pulley, when the winch roller rotates to coil the big rope, the speed of pulling the big rope on the rope pulley is controlled by the pressure of the pressure wheel, the big rope between the winch roller and the rope pulley is ensured to be always in a straightening state, and the coiling tightness of the big rope is ensured; because the whole operation process does not need an operator to tightly pull the big rope by hand or a hammer to strike the big rope on the roller, the operation safety is ensured.

Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1 to 4. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
The utility model relates to a dead line fixing device which is the prior art and comprises a fixed base 01, a rope wheel 02, an anti-jumping bar 03 and a sensor 4, wherein the rope wheel comprises two wheel plates 021 arranged at intervals and a wheel core 022 positioned between the two wheel plates 021; the wheel core 022 is a wheel body with a rope groove on the outer circumferential surface; wheel core 022 is fixed coaxially with wheel plate 021, and the outer diameter dimension of wheel plate 021 is greater than the outer diameter dimension of wheel core 022; the anti-jumping rod 03 sequentially penetrates through the two wheel plates to be connected with the anti-jumping nut; the position of the big rope in the rope groove is limited by the skipping prevention rod 03 (see fig. 1 and fig. 2 in particular).
As shown in fig. 1 to 4, the utility model provides a rope pressing device for a dead rope fixer, which comprises a pressing wheel 1 and a pressing rod 2; the pressure lever 2 comprises a connecting end and a force application end, and the connecting end of the pressure lever 2 is fixed on the pressure wheel 1; the eccentric hole 11 is arranged on the pressing wheel 1, and the pressing wheel 1 is rotatably sleeved on the anti-jumping rod 03 through the eccentric hole 11, so that the outer circular surface of the pressing wheel 1 is close to or far away from the big rope on the rope wheel 02, and the purpose of adjusting the pressure of the big rope on the rope wheel 02 is achieved.
As shown in fig. 4, an annular groove adapted to the outer diameter of the large rope is formed on the outer circumferential surface of the pressing wheel 1 to increase the contact area between the pressing wheel 1 and the large rope and prevent slipping.
It can be understood that, in order to prevent the axial movement of the pressure roller 1 on the anti-jump rod 03, the thickness of the pressure roller 1 needs to be equal to the distance between the two wheel plates 021, or the anti-jump rod 03 is sleeved with a limit sleeve 3 for limiting the axial movement of the pressure roller 1, which is not limited; the axial position of the pressing wheel 1 is preferably limited by the limiting sleeve 3 in the embodiment.
