Detailed Description

The present invention will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention easy to understand.

As shown in fig. 1 to 5, an adjustable roller rope guide comprises a mounting frame 1, two oval long rollers 2 with adjustable intervals are connected to the mounting frame 1, two movable seats 3 which are close to or far away from each other are slidably mounted on the long rollers 2, short rollers 4 which are vertically distributed on the same plane with the long rollers are mounted on the movable seats 3, fixed sleeves 5 which are connected with the mounting frame 1 through bearings are fixed on the long rollers 2, rotating sleeves 6 which are matched with the movable seats 3 are sleeved on the long rollers 2, a first adjusting mechanism 7 is connected to the movable seats 3, and a second adjusting mechanism 8 is connected to the long rollers 2.

Through this kind of mode, first adjustment mechanism 7 and second adjustment mechanism 8 can be to long roller 2 interval and short roller 4 interval in the rope guide are adjusted, because need adjust the interval in two directions, if all adopt the regulation interval of slip mode, whole rope guide holistic structural stability is relatively poor, be difficult to ensure the rope guide effect, adopt and be oval long roller 2, rotate long roller 2, can adjust the interval between the long roller 2 for whole rope guide's stability obtains guaranteeing.

The first adjusting mechanism 7 comprises a connecting block 71 connected with the movable seat 3, a double-headed screw 72 matched with the connecting block 71 and arranged on the mounting frame 1, and a rotary hand wheel 73 connected with the double-headed screw 72. In use, the rotation of the double-ended screw rod 72 drives the two movable bases 3 to move towards or away from each other, changing the spacing between the short rollers 4.

The second adjusting mechanism 8 comprises a knob 81 connected with the long roller 2, clamping plates 82 which are symmetrically arranged on the upper side and the lower side of the long roller 2 and uniformly distributed with teeth 821, a small double-end screw 83 which is arranged on the mounting frame 1 and matched with the clamping plates 82, and a hexagonal plate 84 connected with the small double-end screw 83. When in use, the knob 81 adjusts the rotation of the two long rollers 2, the distance between the long rollers 2 is changed, after the small double-headed screw 83 is rotated, the clamping plates 82 are mutually close, and the positions of the long rollers 2 are fixed through the teeth 821.

The short roller 4 is obliquely arranged on the movable seat 3 near the center of the mounting frame. In this way the wire rope is brought into contact with the short rollers 4 avoiding the wire rope coming into contact with the mobile seat 3.

The rotary sleeve 6 comprises a cylindrical block 61, an elliptical hole 62 formed on the cylindrical block 61, and an annular protrusion 63 fixed on the outer circular surface of the cylindrical block 61 and matched with the movable seat 3. The movable seat 3 is internally provided with a chute 3a matched with the annular bulge 63. In this way, the rotating sleeve 6 is slid along the long roller 2, and the annular projection 63 makes the long roller 2 rotatable in the moving seat 3 via the rotating sleeve 6.

The bottom of the mounting frame 1 is provided with a rope passing hole 1a.

The method of use of the invention is further described below:

in operation, the rotating hand wheel 73 is rotated, the double-headed screw 72 drives the movable seat 3 to move away from or approach each other through the connecting block 71, and the distance between the short rollers 4 is adjusted.

The knob 81 is rotated, the long rollers 2 rotate on the mounting frame 1 and rotate on the movable seat 3 through the rotating sleeve 6, the distance between the long rollers 2 is adjusted by approaching the elliptical long shafts or the elliptical short shafts of the long rollers 2, the small double-headed screw 8 is rotated, the clamping plates 82 are mutually approaching, and the positions of the long rollers 2 are fixed, so that the long rollers can be used.

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
