Detailed Embodiments

[0036] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0037] Figure 1 It is a schematic structural diagram of a coal bunker transfer machine applied to a raw coal bunker according to an embodiment of the present invention. Figure 2 It is a schematic structural diagram of a coal bunker transfer machine according to an embodiment of the present invention.

[0038] See Figure 1 、 Figure 2 In this embodiment, a coal bunker transfer machine is provided, which includes a coal chute 1, a tower crane 2, an amplitude modulation box 3, and a coal receiving hopper 4. Among them, the tower crane 2 includes a tower body 9 and a boom. The tower body 9 is arranged on one side of the raw coal bunker 6; the coal chute 1 is arranged on the boom and can rotate with the boom together, and is used to discharge the coal released from the raw coal bunker 6 to an area far from the raw coal bunker 6; the amplitude modulation box 3 is arranged on one side of the boom and is used for counterweight; the coal receiving hopper 4, the outlet of the coal receiving hopper 4 is connected to the inlet of the coal chute 1, and the coal receiving hopper 4 is used to receive the coal released from the raw coal bunker 6.

[0039] It should be noted that the raw coal bunker 6 includes a coal discharge chute 5, and the coal discharge chute 5 is installed on the side wall of the raw coal bunker 6. The inlet of the coal receiving hopper 4 is located below the coal discharge chute 5.

[0040] Obviously, the coal chute 1 is not horizontally placed, but is inclined between the coal discharge chute 5 and the ground, so that the raw coal can flow to the ground under the action of gravitational potential energy.

[0041] Therefore, the coal bunker transfer machine provided by the embodiment of the present invention can discharge the coal released from the raw coal bunker through the coal chute and slide out to an area far from the raw coal bunker. Therefore, it can increase the storage space for the coal on the ground, facilitate the loading of the coal on the ground, and can reduce the height of the coal pile and increase the storage capacity of the coal.

[0042] The way of arranging the coal chute 1 on the boom can be determined according to actual needs. That is to say, there are many ways to arrange the coal chute 1 on the boom. No matter which arrangement method is adopted, as long as the arrangement method can make the raw coal in the raw coal bunker flow to an area far from the raw coal bunker, it is no longer necessary to use construction machinery such as bulldozers and loaders in the prior art to push the coal away, and the problems in the prior art can be solved and corresponding effects can be achieved.

[0043] There are many ways to arrange the coal chute 1 on the boom. In this embodiment, the following optional implementation manners are provided.

[0044] As a possible implementation method, refer to Figure 2 and Figure 5 , the boom includes a main boom 8 and a counterweight boom 11. The main boom 8 is arranged on one side of the tower body 9, and the counterweight boom 11 is arranged on the other side of the tower body 9; a tower cap 10 is arranged above the tower body 9; the coal chute 1 passes through the slewing section 29 between the tower body 9 and the tower cap 10 and is suspended below the main boom 8 by a number of suspension cables 7.

[0045] It should be noted that the tower crane 2 is modified on the basis of the original tower crane. For example, the hoist is cancelled, the luffing trolley is cancelled, and the counterweight is cancelled. Instead, an amplitude adjustment box 3, a coal receiving funnel 4 and a coal chute 1 are added.

[0046] In some embodiments, the tower cap 10 is respectively connected to the main boom 8, the counterweight boom 11 and the amplitude adjustment box 3 through the pull cables 12.

[0047] Refer to Figure 3 and Figure 4 , the counterweight boom 11 adopts a truss structure. A first hinge seat 16 is arranged at the end of the lower chord of the counterweight boom 11. An ear seat 20 is arranged at the bottom of one end of the amplitude adjustment box 3 close to the counterweight boom 11. The first hinge seat 16 and the ear seat 20 are connected by a first pin shaft 17. A second hinge seat 13 is arranged at the end of the upper chord of the counterweight boom 11. A through hole is arranged on the upper side of one end of the amplitude adjustment box 3 close to the counterweight boom 11. A screw 15 is installed in the through hole. One end of the screw 15 is connected to the second hinge seat 13 through a second pin shaft 14, and the screw 15 and the amplitude adjustment box 3 are fixed by a nut 21.

[0048] As a possible implementation method, the number of nuts 21 is 2, which are respectively installed on the inner and outer sides of the box wall of the amplitude adjustment box. The inclination angle of the coal chute 1 is adjusted by rotating the nut 21.

[0049] In a specific example of the present invention, a third hinge seat 18 is installed on an inner side surface of the amplitude adjustment box 3, a third pin shaft 19 is installed on the third hinge seat 18, and the third pin shaft 19 is connected to the tower cap 10 through the pull cable 12.

[0050] Advantageously, the coal receiving funnel 4 is arranged at one end of the amplitude adjustment box 3 away from the counterweight boom 11, and the coal receiving funnel 4 is fixed to the amplitude adjustment box 3. Refer to Figure 6, the coal receiving hopper 4 includes a straight pipe section 23, an elbow section 25, a tapered pipe section 26, a closing section 27, and an arc-shaped notch section 28. Among them, for the arc-shaped notch section 28, the center of the arc-shaped notch section 28 is concentric with the center of the slewing section 29. Such a setting enables the coal placed in the coal discharging chute 5 to be received during the partial slewing of the tower crane 2. For the closing section 27, the top of the closing section 27 is connected to the bottom of the arc-shaped notch section 28. The two ends of the closing section 27 are arc-shaped and inclined towards the middle to form a closing, which can introduce the coal entering the partial arc-shaped notch section 28 into the tapered pipe section 26. The opening of the tapered pipe section 26 is larger at the top and smaller at the bottom, and the top of the tapered pipe section 26 is connected to the bottom of the closing section 27; for the elbow section 25, the top of the elbow section 25 is connected to the bottom of the tapered pipe section 26, and the elbow section 25 makes the inclination angle of the straight pipe section 23 coincide with the inclination angle of the coal chute 1. For the straight pipe section 23, one end of the straight pipe section 23 is connected to the bottom of the elbow section 25, and the other end of the straight pipe section 23 is provided with a flange 22, and the flange 22 is connected to the coal chute 1.

[0051] In some embodiments, to increase the stability of the amplitude modulation box 3, a plurality of mounting holes 24 are opened on the side of the closing section 27 close to the tower crane 2. The mounting holes 24 are used to pass through bolts to be fixed to the amplitude modulation box 3.

[0052] The installation process of the coal bin transfer machine in this embodiment during actual use is as follows: Install the tower crane 2 on one side of the raw coal bin 6 provided with the coal discharging chute 5. Remove the hoist and the luffing trolley at the top of the tower crane 2, cancel the counterweight at the end of the balance arm 11. At the end of the balance arm 11, insert the screw 15 into the through hole at one end of the amplitude modulation box 3, and screw nuts at both ends of the amplitude modulation box plate. Insert the first pin shaft 17 into the first hinge seat 16, and insert the second pin shaft 14 into the second hinge seat 13, then connect the amplitude modulation box 3 to the end of the balance arm 11. According to the need of the inclination angle of the coal chute 1, adjust the amplitude modulation box 3 to the required angle by changing the positions of the nuts 21 at both ends of the box plate, and fix the amplitude modulation box 3 in place with the pulling cable 12 connected to the tower cap 10 and the third pin shaft 19; Connect the coal receiving hopper 4 and the coal chute 1 together with multiple bolts passing through the holes in the flange 22. Use a crane to lift the coal receiving hopper 4 and the coal chute 1 together, pass the coal chute 1 along the slewing section 29, and lift it to the designated position. Fix the coal receiving hopper 4 and the amplitude modulation box 3 together with multiple bolts passing through the mounting holes 24. Then, use multiple suspension cables 7 to hang the coal chute 1 obliquely under the boom 8.

[0053] During the operation of the bunker coal transfer machine, the coal discharged from the coal discharge chute 5 is discharged by its own weight through the coal receiving hopper 4 and the coal chute 1 to one end far from the coal discharge chute 5. When the discharged coal reaches a certain height, the rotary joint 29 is remotely operated to rotate, so that the coal chute 1 rotates along with it to a designated position to continue discharging coal. When it is necessary to directly discharge coal under the coal discharge chute 5, just rotate the rotary joint 29 to make the coal receiving hopper 4 leave the coal discharge chute 5, and the coal can be discharged near the raw coal bunker 6.

[0054] In summary, the bunker coal transfer machine provided by the embodiment of the present invention has the following technical effects: 1. The coal storage capacity can be increased; the coal discharged from the coal discharge chute slides out through the coal chute, and the distance exceeds 50 meters, correspondingly increasing the storage space for the coal on the ground. 2. There are fewer transmission mechanisms; in the bunker coal transfer machine, the hoist is removed, and only the rotary mechanism remains in the transmission mechanism. Moreover, there is no transmission mechanism in the coal receiving hopper and the coal chute. In this way, there are fewer transmission mechanisms in the bunker coal transfer machine, which can correspondingly reduce the failure rate and the number of high-altitude maintenance operations. 3. The coal discharge location can be selected; due to the coal receiving hopper provided with an arc-shaped notch section, through the local rotation of the tower crane, the coal on the ground can be stacked in a fan shape far from the coal discharge chute. In this way, according to needs, the coal on the ground can be discharged to a place closer to the parking space of the coal transport vehicle, facilitating the loading of the coal on the ground.
