Description

Technical Field

[0001] The utility model relates to the technical field of tunneling machines, in particular to a power supply cable winding device for tunneling machines used in coal mines. Background Art

[0002] The cantilever roadheader is a kind of mechanical equipment commonly used in coal mining. The normal operation of the cantilever roadheader requires a stable power supply, so a cable reel is usually placed behind the whole machine. The cable is wound and fixed on the cable reel. The end of the cable away from the reel is electrically connected to the roadheader. In order to meet the movement of the roadheader within a certain range, a longer cable is reserved between the roadheader and the reel.

[0003] The cable between the reel and the tunnel boring machine is usually scattered on the ground because it is reserved for a long time. The tunnel boring machine will drag the cable on the ground during its forward movement. The dragging and scraping of the cable on the ground can easily cause a large amount of wet coal to adhere to the cable and damage the insulation layer of the cable. During the backward movement of the tunnel boring machine, it is necessary to reel up the longer cable in time and move the excess length of the cable to the side of the whole machine. Otherwise, the track wheel of the tunnel boring machine will easily press on the cable and cause damage to the cable. However, it is not easy to quickly reel up and move the cable between the reel and the tunnel boring machine during the backward movement of most tunnel boring machines. Utility Model Content

[0004] The utility model aims to provide a power cable reeling device for a coal mine roadheader to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A power cable reeling device for a coal mine boring machine, comprising:

[0007] A bottom plate, a crawler vehicle is fixedly mounted on the bottom of the bottom plate, two support seats 1 are fixedly mounted in the middle of the bottom plate, and two support seats 2 are fixedly mounted at both ends of the bottom plate;

[0008] A winding mechanism is arranged at the top of the two support seats, the winding mechanism comprises a winding shaft rotatably connected to the support seat, both ends of the winding shaft are sleeved and fixed with inclined winding wheels, a cable is wound around the outer side of the winding wheel, and a connecting cable is electrically connected between the cables on the two winding wheels;

[0009] A driving motor, used for driving the reel to rotate;

[0010] There are two cleaning mechanisms, which are respectively arranged between two adjacent support seats.

[0011] Furthermore, the cable on one of the winding wheels is electrically connected to the peripheral roadheader, and the cable on the other winding wheel is wound and fixed to the peripheral winding roller.

[0012] Furthermore, a counterweight ball is slidably connected in series at one end of the cable away from the winding wheel.

[0013] Furthermore, the cleaning mechanism includes:

[0014] Two carrier plates, and cleaning brushes are fixed on the side of the carrier plate close to the cable;

[0015] A plurality of connecting seats, and both ends of the carrier plate are fixedly connected to the connecting seats at the corresponding positions;

[0017] Furthermore, the winding shaft includes a first connecting shaft, both ends of the first connecting shaft are fixedly provided with second connecting shafts, and both ends of the second connecting shaft away from the first connecting shaft are fixedly provided with third connecting shafts.

[0018] Furthermore, a round hole is formed between the first connecting shaft and the second connecting shaft, the connecting cable is arranged inside the round hole, and both ends of the connecting cable respectively penetrate through the winding wheels at the corresponding positions and are electrically connected to the cables at the corresponding positions.

[0019] Furthermore, the second connecting shaft is fixedly connected to the winding wheel, and the second connecting shaft is arranged obliquely.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] 1. By rotatably arranging two winding wheels between the peripheral winding roller and the roadheader, cables are wound between the two winding wheels and the roadheader and the winding roller respectively. The driving motor drives the winding shaft to rotate so that the two winding wheels rotate synchronously. Since the winding directions of the cables on the two winding wheels are opposite, the two winding wheels can rotate to wind up the cable from two directions at the same time, which is convenient for quickly winding up the too long cable between the winding roller and the roadheader when the roadheader retreats. On the contrary, when the output end of the driving motor rotates in the reverse direction, the two winding wheels will rotate simultaneously to release the cable, which is convenient for quickly arranging the longer cable between the winding roller and the roadheader when the roadheader advances.

[0022] 2. By arranging a winding mechanism between the peripheral take-up roller and the roadheader, the winding mechanism is supported at the middle of the long cable, which can prevent the cable from piling up on the ground to a certain extent and prevent the cable from being damaged by being dragged by the roadheader. The winding mechanism is installed and fixed on the peripheral crawler vehicle, and the movement of the crawler vehicle can adjust the support position of the cable, which is convenient for evacuating the too long cable to the side of the roadheader in time when the roadheader retreats. When the roadheader advances, it is also convenient to move and convey the spare length cable between the winding mechanism and the take-up roller towards the roadheader, so as to realize short-distance cable conveyance during the process of not operating the winding mechanism to meet the needs of the roadheader's advance.

[0023] 3. By sleeving and fixing the winding wheel on the obliquely arranged connecting shaft II, when the winding shaft on the support base I rotates integrally, the winding wheel will swing left and right to wind the cable, so that the cable can swing horizontally and wind longitudinally and twitch on the cleaning brushes when passing through the two cleaning brushes, which is convenient for fully cleaning the impurities remaining on the outer side of the cable and improving the cleaning efficiency of the cable to a certain extent.

Detailed Embodiment

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Example 1. Refer to Figures 1-6 , in the embodiment of the present utility model, a power supply cable winding device for a coal mine roadheader includes a bottom plate 100. A crawler vehicle is fixedly installed at the bottom of the bottom plate 100. Two first support seats 110 are fixed in the middle of the bottom plate 100. Two second support seats 120 are fixed at both ends of the bottom plate 100. A winding mechanism 200 is rotatably arranged between the tops of the two first support seats 110. The winding mechanism 200 includes a winding shaft 210 rotatably connected to the first support seats 110. Inclined winding wheels 220 are fixedly sleeved at both ends of the winding shaft 210. A cable 221 is wound outside the winding wheels 220. A connecting cable 230 is electrically connected between the cables 221 on the two winding wheels 220. Among them, a driving motor 300 for driving the winding shaft 210 to rotate is fixedly installed outside the top of one of the first support seats 110. A cleaning mechanism 400 is detachably fixed between the tops of two adjacent second support seats 120. The cleaning mechanism 400 is used to clean impurities such as wet coal on the outside of the cable 221.

[0033] Specifically, by arranging a winding mechanism 200 between the roadheader 600 and the external winding roller 500, the two winding wheels 220 on the winding mechanism 200 wind the two ends of the middle part of the cable 221 from different directions respectively. The driving motor 300 drives the two winding wheels 220 to rotate, so as to realize winding the cable 221 simultaneously from both ends of the middle position of the cable 221, achieving the effect of quickly winding the too long cable 221 in a short time. The driving motor 300 drives the two winding wheels 220 to rotate in the reverse direction, achieving the effect of quickly releasing the cable 221 in a short time. By installing the winding mechanism 200 on the external crawler vehicle, the crawler vehicle can drive the whole cable 221 to move, facilitating the long cable 221 to make way for an open space in the advancing direction of the roadheader 600, preventing the roadheader 600 from pressing on the cable 221, and achieving the effect of protecting the cable 221.

[0034] As Figure 1 and Figure 4 shown, in this embodiment, the cable 221 on one winding wheel 220 is electrically connected to the external roadheader 600, and the cable 221 on the other winding wheel 220 is wound and fixed to the external winding roller 500.

[0035] In this embodiment, the cable 221 on one winding wheel 220 is connected to the roadheader 600, and the cable 221 of the other winding wheel 220 is connected to the external take-up roller 500. The two winding wheels 220 are connected by a connecting cable 230, so that the power supply at the position of the external take-up roller 500 can transmit electric power to the roadheader 600 through the cable 221 for use. Both the roadheader 600 and the take-up roller 500 are devices of the prior art, and the specific working principle will not be elaborated.

[0036] As Figure 2 shown, in this embodiment, a diagonal brace 111 is fixed between the first support base 110 and the second support base 120, so that the take-up mechanism 200 and the cleaning mechanism 400 can be stably supported and fixed on the top of the bottom plate 100.

[0037] As Figure 3 shown, in this embodiment, a support plate for supporting and fixing the driving motor 300 is fixed on the outside of one first support base 110, and further the driving motor 300 is installed and fixed on the first support base 110.

[0038] As Figure 4 and Figure 5 shown, in this embodiment, the winding direction of the cable 221 on one winding wheel 220 is upward, and the winding direction of the cable 221 on the other winding wheel 220 is downward, so that the two winding wheels 220 can wind the cable 221 from two directions simultaneously during the rotation process. The cable 221 on each winding wheel 220 passes through the winding wheel 221 and the second connecting shaft 212, and the two cables 221 extending into the second connecting shaft 212 are electrically connected through the connecting cable 230 inside the first connecting shaft 211, so that the cables 221 on the two winding wheels 220 are conducted.

[0039] As Figure 1 shown, in this embodiment, a counterweight ball 2211 is slidably connected in series at the end of the cable 221 away from the winding wheel 220. The cables 221 at both ends of the take-up mechanism 200 are both pulled by the gravity of the counterweight ball 2211, making the winding and releasing of the cable 221 by the winding wheel 220 smoother.

[0040] As Figure 4 shown, in this embodiment, the take-up shaft 210 includes a first connecting shaft 211, and both ends of the first connecting shaft 211 are fixed with second connecting shafts 212, and one end of the second connecting shaft 212 away from the first connecting shaft 211 is fixed with a third connecting shaft 213.

[0041] In this embodiment, the first connecting shaft 211 is used to fix the two second connecting shafts 212, the second connecting shaft 212 is used to support and fix the winding wheel 220, and the third connecting shaft 213 is used to rotatably connect with the first support base 110 to make the entire take-up shaft 210 rotate.

[0042] AsFigure 4 As shown, in this embodiment, a round hole is provided between the first connecting shaft 211 and the second connecting shaft 212, and the connecting cable 230 is arranged inside the round hole. Both ends of the connecting cable 230 respectively penetrate through the winding wheels 220 at corresponding positions and are electrically connected to the cables 221 at corresponding positions.

[0043] In this embodiment, the connecting cable 230 can be arranged inside the first connecting shaft 211 to conduct and connect the cables 221 on the two winding wheels 220.

[0044] As Figure 4 and Figure 5 shown, in this embodiment, the second connecting shaft 212 is fixedly connected to the winding wheel 220, and the second connecting shaft 212 is arranged obliquely. The obliquely arranged second connecting shaft 212 enables the rotating winding wheel to swing, so that the cable can move and be cleaned on the cleaning brush during the cable winding process.

[0045] As Figure 2 shown, in this embodiment, annular baffles 222 are sleeved and fixed at both ends of the winding wheel 220. The annular baffles 222 are used to prevent the cable 221 from detaching from the winding wheel 220.

[0046] Embodiment Two, based on Embodiment One, is for cleaning the cable 221 while winding the cable 221.

[0047] As Figure 6 shown, in this embodiment, the cleaning mechanism 400 includes two carrier plates 410. Cleaning brushes are fixed on the side of the carrier plate 410 close to the cable 221. Connecting seats 420 are fixed at both ends of the carrier plate 410. Bolts 430 penetrate between adjacent two connecting seats 420 and the top of the second support base 120, and nuts are screwed on the tops of the bolts 430.

[0048] In this embodiment, the connecting seats 420 at both ends of the carrier plate 410 are lapped on the second support base 120, and then the bolts 430 are used to pass through the connecting seats 420 and the second support base 120, and nuts are screwed on the tops of the bolts 430 to detachably mount the carrier plate 410 and the cleaning brushes to the second support base 120. The cable 221 passes through the two cleaning brushes, which is convenient for cleaning the impurities on the outer side of the cable 221. After the cleaning brushes are soiled, the carrier plate 410 can also be detached for replacing the cleaning brushes.
