Description

Technical field:

[0001] The utility model relates to the technical field of winch equipment, in particular to a blocking and protective device for a winch wire rope outlet. Background technology:

[0002] Gold mine winch is a mechanical equipment used to lift ore and other materials in mining and beneficiation. In actual production, large winches are installed in the central control room to facilitate protection, comprehensive control and operation of the winch. However, the conveying wire rope of the winch needs to pass through the wall of the central control room for transportation. For this reason, the central control room is equipped with a wire rope window. Due to the large length of the winch drum, the wire rope will move back and forth horizontally in the window when the winch is running. In the existing technology, in order not to hinder the movement of the wire rope, only strip curtains are installed at the window for simple dust and warmth protection. However, in the cold winter in the north, the strip curtains are difficult to block the invasion of cold wind, and the cold, wind and dust protection functions are limited. The central control room, especially near the window, is cold and the environment is harsh, causing the infrared rope break sensor in the window to frost, resulting in sensor failure or false alarm. At the same time, the wire rope contacts the edge of the window, generating irregular friction, resulting in a short service life of the winch wire rope and prone to rope breakage accidents, which urgently needs to be improved. Utility model content:

[0003] The purpose of the utility model is to provide a blocking and protective device for the wire rope outlet of a winch, so as to solve the technical problems in the prior art that the strip curtains on the wire rope windows in the control room of the winch have poor wind and cold protection effects, leading to sensor failure and a cold and harsh environment in the control room.

[0010] Furthermore, a fan-shaped sealing plate is provided between any two adjacent positioning and anti-wear components, and the sealing plate is fixedly mounted on the inner wall of the wire rope through hole.

[0011] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and a movable plate assembly and a folding telescopic plate are designed at the position of the wire rope window. While fully covering and blocking the wire rope window, the movable plate can move with the movement of the wire rope. While ensuring the normal operation of the winch wire rope, it has good cold and windproof functions, ensures the normal operation of the sensor, and improves the environment of the winch control room.

Specific implementation method:

[0017] like Figure 1 and Figure 2As shown, a blocking and protective device for the wire rope outlet of a winch includes a winch 1, which is installed in a central control room. A window 2 is provided on the wall of the central control room. A movable plate assembly is connected to the window 2 for sliding left and right. A wire rope through hole 6 is provided on the movable plate assembly. Folding and telescopic plates 3 are connected to both sides of the movable plate assembly. The outer end of the folding and telescopic plate 3 is connected to the window 2. The movable plate assembly and the folding and telescopic plate 3 block the window 2.

[0018] like Figure 3 As shown, the movable plate assembly includes an upper plate, a center plate 5 and a lower plate connected in sequence from top to bottom, the wire rope through hole 6 is opened on the center plate 5, and rollers 15 are rotatably connected to the upper and lower plates. Slide grooves 4 are opened at the upper and lower ends of the window 2, and the rollers 15 roll in the slide grooves 4; positioning pins 13 are installed on the upper and lower plates, and pin holes 14 matching the positioning pins 13 are opened at the upper and lower ends of the center plate 5, and the positioning pins 13 are inserted into the pin holes 14.

[0019] In order to increase the service life of the wire rope, less irregular friction, such as Figure 3 and Figure 4 As shown, several positioning anti-wear components are evenly distributed along the circumferential direction in the wire rope through hole 6; the positioning anti-wear components include a stud 7, a compression spring 8, and a positioning column 9 connected in sequence, and several through holes are evenly distributed along the circumferential direction in the wire rope through hole 6, the stud 7 is screwed into the through hole, the end of the positioning column 9 extends into the wire rope through hole 6, and a wear-resistant ball 10 is installed at the end of the positioning column 9; a hemispherical groove is opened at the end of the positioning column 9, the wear-resistant ball 10 is located in the groove, and a magnet 11 is installed at the bottom of the groove, and the magnet 11 magnetically attracts the wear-resistant ball 10.
