Description

Technical Field

[0001] This utility model relates to the field of mine ventilation and dust removal technology, specifically to a limiting and dragging device for fixing a dust removal duct using a mine monorail crane. Background Technology

[0002] Currently, most methods of towing dust removal ducts involve manual labor using long-handled tools to drag the duct from below, followed by securing it with wire. This method has serious drawbacks: firstly, it is extremely labor-intensive, and the personnel standing under the duct are at risk of it slipping and falling, causing injury; secondly, the wire securing is very weak, with the risk of the wire breaking and the duct slipping; it is not only time-consuming and labor-intensive, but also poses safety risks due to working at height.

[0003] Therefore, this utility model provides a limiting and dragging device for fixing a dust removal duct using a mine monorail crane. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a limiting and dragging device for fixing a dust removal duct using a mine monorail crane. The specific technical solution is as follows:

[0005] A limiting and dragging device for fixing a dust removal duct using a mine monorail crane is used to install on the monorail crane track on the roof of the roadway. It includes a connecting plate, a hand-operated winch, a car stopper, and at least two pulley cars. At least two of the pulley cars and the car stopper are sequentially arranged on the track along the roadway mining direction. The pulley cars and the car stopper are slidably connected to the track. The connecting plate is fixedly installed at the bottom of the car stopper. The hand-operated winch is fixed to the top of the connecting plate. A pull rope is wound around the surface of the hand-operated winch, and one end of the pull rope is pulled out and connected to a lifting lug at the bottom of the pulley car near the car stopper. The dust removal duct is suspended from the lifting lug at the bottom of the pulley car by the rope and a hook.

[0006] Preferably, the pulley cart is equipped with a braking device.

[0007] Preferably, the pull rope and the suspension rope are made of three-point steel wire rope.

[0008] Preferably, the connecting plate is made of steel.

[0009] The beneficial effects of this utility model are:

[0010] This utility model has a simple structure and is easy to install. The dust removal duct can be moved along the mining direction of the roadway by pulling the rope with a hand winch. The movement of the dust removal duct is limited by a car stop, which not only reduces the labor intensity of manually dragging the dust removal duct and reduces labor costs, but also avoids the safety hazards caused by the dust removal duct slipping off. Attached Figure Description

[0011] The accompanying drawings constituting this application are provided to further understand this application and do not constitute an undue limitation of this application.

[0012] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0013] In the diagram, 1-track; 2-stop device; 3-pulley; 4-connecting plate; 5-hand winch; 6-pull rope; 7-dust removal duct; 8-suspension rope. Detailed Implementation

[0014] The specific implementation of the limiting and dragging device for fixing a dust removal duct using a mine monorail crane provided by this utility model will be further described in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a limiting and dragging device for fixing a dust removal duct using a mine monorail is installed on the monorail track 1 on the roof of the roadway. Specifically, it includes a connecting plate 4 and a hand winch 5. At least two sets of pulley cars 3 and car stoppers 2 are arranged sequentially along the roadway mining direction on the track 1. The pulley cars 3 and car stoppers 2 are slidably connected to the track 1.

[0016] Preferably, the connecting plate 4 is fixedly installed at the bottom of the barrier 2; the hand-operated winch 5 is fixed at the top of the connecting plate 4; a pull rope 6 is wound around the surface of the hand-operated winch 5, and one end of the pull rope 6 is pulled out and connected to the lifting lug at the bottom of the pulley 3 near the barrier 2; the dust removal duct 7 is suspended from the lifting lugs at the bottom of at least two sets of pulley 3 by the hanging rope 8 and the hook, which can ensure the stability of the dust removal duct 7.

[0017] Preferably, the pulley cart 3 is equipped with a braking device. When it moves to the required working area, the braking device is released and locked to prevent the dust removal duct from moving back and forth on the track 1.

[0018] Preferably, the pull rope 6 and the suspension rope 8 are made of three-point steel wire rope.

[0019] Preferably, the connecting plate 4 is made of steel.

[0020] In use, the dust removal duct is moved to the working area by moving the pulley cart 3 and the stopper 2, and the brake device of the pulley cart 3 is activated to fix it. As the mining work progresses, the workers only need to move the stopper 2 forward and use the hand winch 5 to retrieve the rope 6 so that the dust removal duct 7 can be moved along the mining direction by the pulley cart 3 to the next mining area for dust removal and environmental purification. At the same time, the stopper 2 can limit the movement of the dust removal duct 7 during the dragging process.

[0021] Traditional methods of dragging dust removal ducts mostly involve manual labor using long-handled tools while standing under the duct, followed by securing it with wire. However, this method has serious drawbacks: firstly, it is extremely labor-intensive, and the duct is prone to slippage and falling, posing a risk of injury; secondly, the wire securing is often weak, with the risk of the wire breaking and the duct slipping again. This method is not only time-consuming and labor-intensive but also poses safety risks associated with working at height. In contrast, this new invention features a simple structure and easy installation. A hand-operated winch retracts the rope to move the dust removal duct along the mining direction of the tunnel; a stopper limits the movement of the duct, reducing the labor intensity and costs of manual dragging and preventing the safety hazards caused by the duct slipping.

These terms are merely used to facilitate the description of the structural relationships of the various components or elements of this utility model and do not specifically refer to any part or element of this utility model; they should not be construed as limiting this utility model.

For those skilled in the art, the specific meaning of the above terms in this utility model can be determined according to the specific circumstances, and they should not be construed as limiting this utility model.

[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
