Its advantages are: during the replacement process of the first rope of the vertical well multi-rope friction hoist, the large deformation of the filling material can provide positive pressure on the steel wire rope, fix the position of the steel wire rope, and protect the steel wire rope while making up for the diameter difference between the old and new steel wire ropes. effect.

Description

Composite board for head rope replacement of vertical well multi-rope friction hoist

technical field

The utility model relates to a board card for replacing the first rope of a vertical shaft multi-rope friction hoist, in particular to a composite board card for replacing the first rope of a vertical shaft multi-rope friction hoist.

Background technique

The replacement process of the first rope of the multi-rope friction hoist of Lijing is usually "the new rope brings the old rope, and the old rope spits out the new rope". During this process, in order to prevent the new rope from falling into the shaft, or the new rope from being entangled with the old rope, it is necessary to connect the new rope to the old rope at intervals to bear the weight of the old rope in sections while maintaining the position of the new rope. At the present stage, iron clamps are often used in construction to complete this work, but the iron clamps have the following defects: 1. There is a difference in the diameter of the new rope and the old rope, and the difference may reach 10%. When holding the new rope, it is difficult to clamp the old rope, and it is easy to cause the new rope to fall into the shaft; 2. When the new and old ropes are alternately stressed, the length of the new and old ropes will change, and the steel wire rope needs to slide in the board, and the iron board will be broken. Damage the wire rope.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and to provide a board card for replacing the first rope of the vertical shaft multi-rope friction hoist. During the replacement process of the first rope of the multi-rope friction hoist in the vertical shaft, the plate card provides positive pressure on the steel wire rope through the large deformation of the filling material and fixes the position of the steel wire rope. It can also protect the steel wire rope while making up for the diameter difference between the old and new steel wire ropes. .

The technical scheme of the utility model is realized as follows: a plate card for replacing the head rope of a vertical shaft multi-rope friction hoist includes two pieces of plate clips, bolts, skeletons, and steel wire ropes. The material is poured into a plate clamp, and there are bolt holes on the two clamps, and a rope groove is opened on the inner contact surface of the two clamps. The steel wire rope is placed in the rope groove, and the two clamps are connected and fixed by bolts and nuts. The inner contact surface of the piece plate clamped with the rope groove is closely attached, and gaskets are set on both sides of the bolts and nuts.

The skeleton is a steel skeleton.

The number of the rope grooves is twice the number of the wire ropes of the hoist, and the depth of the rope grooves is smaller than the radius of the wire ropes.

The filling material is polyurethane elastomer polymer material.

After the utility model adopts the above scheme, it has the following beneficial effects:

(1) The board is light in weight, easy to operate and reusable;

(2) The board clamps the steel wire rope through the large deformation of the filling material, which can make up for the diameter difference between the old and new ropes;

(3) The filling material has good elasticity, which can protect the steel wire rope and avoid damage to the steel wire rope when the old and new steel wire ropes are stressed alternately.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural diagram of the utility model;

FIG. 2 is an enlarged cross-sectional view of the board in FIG. 1 .

In the figure, 1. Filling material, 2. Skeleton, 3. Steel wire rope, 4. Plate clamp, 5. Nut, 6. Gasket, 7. Rope groove, 8. Bolt hole, 9. Bolt.

Detailed ways

With reference to Fig. 1 and Fig. 2, the utility model comprises two plate clips 4, bolts 9, nuts 5, skeleton 2, steel wire rope 3, skeleton 2 and filling material 1 are poured into plate clip 4, and described skeleton 2 is a steel skeleton , can provide strength for the board; the filler material 1 is made of polyurethane elastomer polymer material, which can protect the wire rope and reduce the weight of the board clip 4 at the same time. A bolt hole 8 is opened on the two-piece plate clamp 4, and a rope groove 7 is opened on the inner contact surface of the two-piece plate clamp 4. The steel wire rope 3 is placed in the rope groove 7, and the two-piece plate clamp 4 passes through the bolt 9 and the nut 5. Connect and fix, on the both sides of bolt 9, nut 5, gasket 6 is sleeved, tighten nut 5, make the contact surface of two pieces of plate clamp 4 belt rope grooves 7 close. Like this, the relative position of steel wire rope 3 has just been fixed. Simultaneously, because the depth of the rope groove 7 is less than the radius of the steel wire rope 3, the filling material 1 in the plate clamp 4 will be deformed, and a positive pressure will be applied to the steel wire rope 3 to bear the weight of the steel wire rope 3. The deformation of the filling material 1 provides a positive pressure on the steel wire rope and bears the weight of the steel wire rope.
