Description

Hoist lifting hole plugging device

The technical field is as follows:

the utility model relates to a hoist lifting hole shutoff field especially relates to a hoist lifting hole plugging device.

Background art:

in the hydraulic conveying engineering, a plurality of regulating brakes and inverted siphon brakes are arranged along the whole channel, and the lifting of the existing gate is generally completed by winding and unwinding a steel wire rope through the rotation of a winding drum. Reverse threads are arranged on two sides of the winding drum, two ends of the steel wire rope are wound in the reverse threads respectively, and the middle of the steel wire rope penetrates through a lifting pulley block connected with the gate downwards through a lifting hole. When the winding drum rotates to drive the gate to ascend, the steel wire ropes in the vertical state move oppositely and are arranged in the thread groove of the winding drum in order, and the distance between the two ends of the steel wire ropes is continuously shortened; when the winding drum rotates to drive the gate to descend, the steel wire rope moves relatively, and the distance between the two ends of the steel wire rope is increased continuously. Because the position of the steel wire rope is constantly changed, an orifice must be reserved, and the steel wire rope can smoothly run in a working range.

Because the orifice is reserved, birds, winged insects, dust and the like can enter the room to pollute the indoor environment, threaten the electrical elements of equipment and leave potential safety hazards for the normal operation of the hoisting hoist. In order to prevent birds and insects from entering, a common treatment method is to cut a rubber block into teeth from the middle, leave a proper gap for the steel wire rope to walk around, and then fix the rubber block on a cover plate at the periphery of an opening. Although the mode can play a part of protection role, the rubber plate often rubs with the steel wire rope because the sealing is impossible, the rubber plate is easy to age and damage, the problem cannot be solved fundamentally, and the image of the engineering project is also influenced.

Therefore, the hoisting hole plugging device capable of effectively solving the problems of potential safety hazards of electrical equipment of the hoist chamber, poor environmental sanitation and the like is developed, and becomes a technical problem to be solved urgently in the industry.

The utility model has the following contents:

the utility model discloses a remedy prior art not enough, provide a hoist lifting hole plugging device, can remain the leakproofness of lifting hole all the time when wire rope removes, avoid birds, winged insect and dust etc. can get into indoor pollution indoor environment, eliminated the potential safety hazard, solved the problem that prior art exists.

The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be:

a hoist lifting hole plugging device includes:

the two sliding grooves are symmetrically arranged on two sides of the hoisting hole;

the two movable shields are respectively and movably arranged in the two sliding grooves on the outer sides of the two steel wire ropes, and the steel wire ropes penetrate through the movable shields to drive the movable shields to move back and forth;

the two fixed shields are respectively buckled outside the two sliding chutes on the outer sides of the two steel wire ropes;

the telescopic protective cover is arranged in the two sliding grooves between the two steel wire ropes, and two ends of the telescopic protective cover are fixedly connected with the two movable protective covers respectively.

The telescopic protective cover is a stainless steel scale armor telescopic protective cover.

And a flexible sheath is arranged between the steel wire rope and the movable protective cover.

Two guide wheels are installed in the movable shield through vertical plates, and the steel wire rope penetrates between the two guide wheels.

The utility model adopts the above technical scheme, have following advantage:

carry out the shutoff through the hole for hoist between the telescopic protection casing to two wire rope, carry out the shutoff through the hole for hoist of removing the guard shield and fixed guard shield to two wire rope outsides, can remain the leakproofness of hole for hoist all the time when wire rope round trip movement, simple structure, the outward appearance is clean and tidy, simple to operate can effectively avoid birds, winged insect and dust etc. to get into indoor pollution indoor environment, has eliminated hoist lock chamber electrical equipment potential safety hazard.
