Description

Technical Field

[0001] The invention relates to the technical field of winch control room protection, and in particular to a protection device for a mining shaft tower winch control room. Background Art

[0002] A mine is a hoisting, evacuation and ventilation passage for underground mining. A winch control room will be built next to the open-air mine tower. The winch equipment is installed in the control room, and the wire rope is lifted and lowered underground by the winch through the rotating wheel of the tower.

[0003] The winch control room is a closed, high-cleanliness area with a variety of equipment and facilities installed inside. The requirements for dust prevention, protection, and equipment temperature control are relatively strict. The wire rope needs to be hoisted to the sheave of the well tower through the winch for lifting operations. In the past, an open window had to be reserved from the control room to the well tower. First, it is to ensure that the wire rope can be connected to the sheave through the winch to ensure normal operation; second, it is to facilitate the control room personnel to observe the working conditions of the sheave and wire rope. Due to the large elasticity and range of motion of the wire rope, the reserved window opening is large, and the wire rope is an external exposed component, which has a great impact on the dust prevention and protection of the winch control room. The sand and dust aggravate the wear of the equipment, and the temperature of the equipment in the control room is difficult to control, resulting in great safety hazards in the lifting system. Summary of the invention

DETAILED DESCRIPTION

[0026] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0027] Example 1

[0028] This embodiment is used to specifically illustrate the present invention.

[0029] like Figure 1 , Figure 2 and Figure 6As shown, the present invention includes a protective window frame 1, wherein a card slot is provided in the protective window frame 1, and a protective glass 2 is installed in the card slot. A roller 3 is rotatably connected between the upper and lower parts of the protective window frame 1; two damping rollers 6 with damping rollers are respectively installed at the upper and lower parts of the protective window frame 1, and the protective window frame 1 is slidably matched with a mounting frame 8 through the damping rollers 6. The mounting frame 8 is welded to a long bolt fixed inside the wall, and other fixing methods can also be used here. A limiting bracket 7 is also welded on the left and right sides of the mounting frame 8, and two anti-collision rubbers 11 are arranged on the limiting bracket 7. A sealed dustproof brush 13 is fixed to the back of the upper and lower parts of the protective window frame 1, and the fixing bracket 4 is welded in the middle of the upper and lower parts of the protective window frame. The bottom of the fixing bracket 4 is fixed to the base of the spherical shaft 10 by screws, and the bottom of the hydraulic buffer 9 and the rotating rod of the spherical shaft 10 are also fixed by screws. The top of the hydraulic buffer 9 is fixed to the rotating rod of another spherical shaft 14 by screws. The base of the spherical shaft 14 is fixed to the wire rope lubrication device 13 by screws, and the wire rope lubrication device 13 is connected to the dust removal brush 5 through the connecting plate 21. The back mechanism of the protective window frame 1 is arranged symmetrically up and down.

[0030] The working principle of the present invention is as follows: the wire rope of the hoisting equipment in the hoisting control room passes through the wire rope lubrication device 13, the dust removal brush 5 and the two rollers 3 and is connected to the tower sheave. When the equipment starts the lifting operation, the wire rope begins to tighten and be recovered, and the roller 3 begins to rotate due to the friction. The roller 3 rotates while reducing the wear effect on the wire rope. A large amount of dust is attached to the wire rope exposed outside the control room. During the recovery process, the dust removal brush 5 brushes off most of the dust, reducing the probability that the dust is brought into the control room by the wire rope and causing damage to the equipment. The wire rope passing through the dust removal brush 5 is then lubricated by the wire rope lubrication device 20, which slows down the rusting speed of the wire rope on the one hand and reduces the dust raising phenomenon of the wire rope on the other hand. If the wire rope has a small sway, the hydraulic buffer 9 and the wire rope lubricating device 13 will limit the up and down movement of the wire rope, and the roller 3 and the damping roller 6 with the damping roller will limit the left and right movement of the wire rope. However, if the wire rope has a large sway, in order to avoid damage, the protective window frame 1 will be driven by the damping roller 6 to move left and right on the mounting frame 8, and the wire rope lubricating device 13 will move up and down under the action of the hydraulic buffer 9 to adapt to the sway of the wire rope. When the protective window frame 1 moves to both sides of the mounting frame 8, the anti-collision rubber 6 provided on the limit bracket 7 will play a role in limiting and buffering.

[0031] Example 2

[0032] like Figure 3As shown, the wire rope lubricating device 13 includes a wire ring 14, a sleeve 15, a stopper 16, a pressure spring 17, a plug 18, a through hole 19, and an oil storage tank 20; circular holes are arranged on both sides of the wire rope lubricating device 13, and the diameter of the circular holes can be larger than the diameter of the wire rope. A wire ring 14 is fixed on the outside of the circular holes on both sides, and the diameter of the wire ring 14 should be slightly larger than the diameter of the wire rope; a sleeve 15 is welded on the upper and lower sides of the inner wall of the wire rope lubricating device 13, and other fixing methods can also be used here; a through hole 19 is arranged at one end of the sleeve 15, and a thread is arranged on the inner wall of the other end; the plug 18 is connected to the pressure spring 17, and the pressure spring 17 is connected to the stopper 16; the diameter of the plug 18, the pressure spring 17, and the stopper 16 is the same as the inner wall diameter of the sleeve 15, and the selected plug 18 should be compatible with the thread of the sleeve 15.

[0033] The working principle of the present invention is: when the hoisting device is performing a lifting operation, if it is necessary to lubricate the wire rope, the operator unscrews the plug 18, adds solidified lubricating butter therein, and a little more lubricating butter should be added here, and then screws back the plug 18. Since the part of the wire rope in the oil storage bin 20 is in direct contact with the lubricating butter, the wire rope is continuously lubricated during the recovery process. At the same time, since more lubricating butter is added at the beginning, the pressure spring 17 will be in a compressed state. When the lubricating butter around the wire rope is taken out of the oil storage bin 20, the pressure spring 17 will push the block 16 to slide in the sleeve 15, and then squeeze the lubricating butter to make it continuously fill around the wire rope. The wire ring 14 arranged outside the circular hole will play a certain role in sealing the oil storage bin 20 and preventing the lubricating butter from leaking. In order to reasonably control the use of lubricating butter, the through hole 19 can be set smaller, the pressure spring 17 can select a spring with a smaller thrust, and the natural elongation length of the pressure spring 17 should not be greater than the length of the sleeve 15. The wire ring 14 is used for sealing because the forward and backward movement of the wire rope will generate greater friction. The use of the wire ring 14 can effectively increase the service life of the device. If there are other materials that are more resistant to the friction of the wire rope, they can also be used to replace the wire ring 14.

[0034] Example 3

[0035] like Figure 4 and Figure 5 As shown, the dust removal brush 5 is square on the outside and circular on the inside; a rectangular slot is provided in the middle of the connecting plate 21 .

[0036] The working principle of the present invention is: the dust removal brush 5 is connected to the wire rope lubricating device 13 through the connecting plate 21. For the convenience of fixing, the outer shells of the dust removal brush 5 and the wire rope lubricating device 13 are both square. Of course, if the dust removal brush 5 and the wire rope lubricating device 13 are connected in other ways, then their outer shells can be adaptively changed.

[0037] During the wire rope recovery process, the dust removal brush 5 removes the dust on the wire rope, and the dust falls through the rectangular slot of the connecting plate 21. In actual operation, the operator can place a container for collecting dust under the connecting plate. The bristles of the dust removal brush 5 can be made of palm material, which can ensure a good dust removal effect without causing excessive damage to the wire rope.

[0038] Example 4

[0039] like Figure 7 As shown, the bottom of the hydraulic buffer 9 and the fixed bracket 4, as well as the top of the hydraulic buffer 9 and the wire rope lubrication device 13 are connected through a spherical shaft 10, and the spherical shaft 10 is fixed with screws.

[0040] The working principle of the present invention is that when the hoisting device is working, the wire rope will not only shake, but also move back and forth. The use of the spherical shaft 10 enables the hydraulic buffer 9 and the wire rope lubricating device 13 to form a set of mechanisms with a margin of motion. If the wire rope produces a large friction effect on the wire rope lubricating device 13, in order to prevent damage, the mechanism will appropriately translate to adapt to the movement of the wire rope, thereby reducing the harm of the friction effect.
