Description

Technical Field

[0001] The utility model relates to the field of underground spraying equipment, in particular to an anti-twisting rope automatic reciprocating spraying device. Background Art

[0002] Dust reduction in mines is a key task in production safety. The existing dust reduction methods include dust collection by induced draft equipment, water curtain, spray dust reduction, etc. Among them, spray dust reduction equipment has relatively high efficiency and low energy consumption, and has been better promoted and applied.

[0003] The underground spraying device in the prior art is usually driven by a winch and a steel cable, and the rope is prone to tangling during use. In response to this problem, the applicant filed application number 2023220027919, disclosing a mobile reciprocating tunnel cleaning and dust reduction system. The system solves the rope tangling problem existing in the movement of the spraying equipment in the prior art through the transmission form of synchronous wheels and synchronous belts. However, after actual working condition experiments, it was found that there are still technical drawbacks. The most important problem is that the equipment requires an explosion-proof servo motor to work with the electronic control system, synchronous wheels and synchronous belts, resulting in a high cost, and the cost of laying the whole underground is relatively large; and based on the above, due to the dust and humidity in the underground environment, the service life of the synchronous belt and synchronous wheel is short, and the maintenance of the electronic control system is more frequent. This has led to a further increase in the cost of use. In response to the above problems, there is currently a lack of corresponding solutions. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an anti-twisting rope automatic reciprocating spray device which has a simpler structure, a lower overall cost and is easier to maintain while achieving the anti-twisting rope function.

[0005] The equipment includes a power system and a spray system; the power system and the spray system are arranged at intervals;

[0006] The power system includes a winch housing, which is an assembly part used for fixed assembly in the tunnel;

[0007] A winch is rotatably arranged in the winch housing, and a return wheel is fixedly arranged on the opposite side of the winch through an assembly base; a steel cable loop is arranged between the winch and the return wheel;

[0008] The winch is in the form of a V-shaped axle with a smooth transition;

[0009] The winch power is connected to the power mechanism; a travel switch is arranged outside the power mechanism, a bump block is arranged on the steel cable sheath, and the bump block is arranged corresponding to the travel switch;

[0010] The travel switch is connected to the power mechanism via a mechanical valve signal;

[0011] The effect achieved in this way is that the winch in the form of a V-axle can constrain the steel cable loop and the recessed section in the middle; the power mechanism starts the winch to drive the steel cable loop to move, and during the displacement process, the bump block moves to the position of the travel switch, thereby realizing the forward and reverse rotation of the power mechanism, that is, realizing the reciprocating movement of the rope.

[0012] The spray system includes a trolley slideway, which is the assembly basis of the spray system;

[0013] A sliding trolley is arranged in an array on the trolley slideway, a lifting ring is arranged at the lower part of the sliding trolley, and a spray water pipe is passed through the lifting ring;

[0014] The sliding trolley is connected to the steel cable loop by pulling.

[0015] The effect achieved in this way is that the displacement of the steel cable loop drives the sliding trolley to move, that is, drives the spray water pipe to move, and the steel cable loop moves back and forth, driving the spray water pipe to spray the tunnel back and forth.

[0016] The beneficial effect of the utility model is that the utility model solves the problems of high cost and high maintenance rate of the transmission system in the prior art spraying equipment through a simple structure on the basis of realizing the anti-twisting rope function. Its cost and maintenance rate are lower, and it is more valuable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1 , Figure 2 and Figure 3The utility model discloses an automatic reciprocating spraying device for preventing twisting rope, comprising a power system and a spraying system; the power system and the spraying system are arranged at intervals;

[0024] The power system includes a winch housing, which is an assembly part used for fixed assembly in the tunnel;

[0025] A winch 1 is rotatably arranged in the winch housing, and a return pulley 5 is fixedly arranged on the opposite side of the winch 1 through an assembly base; a steel cable loop 4 is arranged between the winch 1 and the return pulley 5;

[0026] The winch 1 is in the form of a V-shaped axle with a smooth transition;

[0027] The winch 1 is connected to the power mechanism 2; a travel switch 21 is arranged outside the power mechanism 2, a bump block 3 is arranged on the steel cable loop 4, and the bump block 3 is arranged corresponding to the travel switch 21;

[0028] The travel switch 21 is connected to the power mechanism 2 via a mechanical valve signal;

[0029] Preferably, the travel switch 21 is a pneumatic travel switch, and the mechanical valve is a pneumatic valve.

[0030] The effect achieved by this is that the capstan 1 in the form of a V-axle can constrain the steel cable loop 4 in the middle recessed section; the power mechanism 2 starts the capstan 1 to drive the steel cable loop 4 to move, and during the displacement process, the bump block 3 moves to the position of the travel switch 21, so that the power mechanism 2 can be reversed, that is, the reciprocating movement of the rope can be achieved. Among them, the pneumatic travel switch and the mechanical valve are more suitable for underground, and meet the requirements of underground fire and explosion prevention.

[0031] The spray system includes a trolley slide 6, which is the assembly basis of the spray system;

[0032] A sliding trolley 7 is arranged in an array on the trolley slideway 6, and a lifting ring is arranged at the lower part of the sliding trolley 7, and a spray water pipe 8 is passed through the lifting ring;

[0033] The sliding trolley 7 is connected to the steel cable loop 4 by pulling.

[0034] The effect achieved in this way is that the displacement of the steel cable loop 4 drives the sliding trolley 7 to move, that is, drives the spray water pipe 8 to move, and the steel cable loop 4 moves back and forth, driving the spray water pipe 8 to spray the tunnel back and forth.

[0035] Furthermore, the power mechanism 2 is a pneumatic motor.

[0036] The effect achieved in this way is to meet the underground explosion-proof requirements at a lower cost.

[0037] Embodiment 1: The steel cable loop 4 is wound around the winch 1 for one circle and is sleeved on the return wheel 5. That is to say, the steel cable loop 4 always wraps around the steel rope on the winch 1 for only one circle, and the loop part only fits the outer half of the return wheel 5 at the return wheel 5 position.

[0038] The effect achieved thereby is that the surrounding position of the steel cable loop 4 on the winch 1 is always concentrated at the central recessed position thereof, thereby avoiding the rope twisting situation.

[0039] Embodiment 2: The number of the collision block 3 is one or two, and when there are two collision blocks 3, the two collision blocks 3 are arranged opposite to each other;

[0040] The stroke opening setting form corresponds to the bump block 3.

[0041] Embodiment 3: The trolley slideway 6 is an I-beam, and the sliding trolley 7 is a rail-holding trolley corresponding to the I-beam.

[0042] Embodiment 4: Refer to the attached drawings of the specification Figure 3 The trolley slide 6 is provided with a spray water pipe receiving section 61 at its tail end.

[0043] Preferably, the spray water pipe receiving section 61 is an arc-shaped slide.

[0044] The effect achieved in this way is that the spray pipe covers the entire length of the trolley slide 6, and when in standby, the spray water pipe 8 is stored in the spray water pipe storage section 61.

[0045] Furthermore, a tensioning mechanism is also provided in the power system.

[0046] Preferably, the tensioning mechanism may be a steel cable puller, a tensioning wheel, etc.
