[0028] Figure 2 A schematic diagram showing the cooperation between the mobile body 10 and the coal car track 1 according to an embodiment of the utility model is shown. Figure 3 FIG. 1 is a schematic diagram of a refractory material transport device 100 according to an embodiment of the present invention. Figure 2 and Figure 3 The utility model proposes a refractory material transportation device 100 for the roof removal and renovation of the coke oven combustion chamber, which includes: a mobile body 10, the mobile body 10 can be movably arranged on a coal car track 1 arranged along the longitudinal direction of the coke oven, and the mobile body 10 has a running track 12 arranged along the transverse direction; an electric hoist 20 for lifting refractory materials, and the electric hoist 20 can be movably arranged on the running track 12.

[0029] In the embodiment of the utility model, the mobile body 10 can be movably arranged on the coal car track 1 along the longitudinal direction, and the electric hoist 20 can be movably arranged on the running track 12 arranged along the transverse direction of the mobile body 10, so that the electric hoist 20 can be moved in the longitudinal and transverse directions to transport the refractory materials to multiple different locations, greatly enhancing flexibility and improving transportation efficiency. Compared with the fixed hoist arranged on the coal loading car in the prior art, the electric hoist 20 arranged on the mobile body 10 of the present application can have a larger lifting capacity and improve the transportation capacity.

[0030] refer to Figure 2 and Figure 3 In some embodiments, the mobile body 10 includes two brackets 11 arranged opposite to each other in the transverse direction and at least one transverse member 13 connecting the two brackets 11, each bracket 11 is movably arranged on each coal car track 1, and the running track 12 is arranged on the top of the two brackets 11. Through such an arrangement, the mobile body 10 can be lightweight, its weight can be reduced and materials can be saved, and it can be ensured that the mobile body 10 can be moved on the coal car track 1 more easily. The brackets 11 and the transverse member 13 can be welded together, or they can also be detachably connected together by means such as threaded connection, snap connection, clamping, etc. Similarly, the brackets 11 and the running track 12 can be welded together, or they can also be detachably connected together by means such as threaded connection, snap connection, clamping, etc. The transverse member 13 can be made of I-beam, for example, and its length can be 150 mm.

[0031] The number of transverse members 13 can be, for example, two, and the two transverse members 13 are respectively connected to the two side areas of the two brackets 11 in the longitudinal direction, so that the middle area of ​​the two brackets 11 in the longitudinal direction can be reserved for setting the running track 12 and the electric hoist 20 thereon. In this way, the electric hoist 20 is generally arranged in the middle position of the mobile body 10 in the longitudinal direction, which can ensure the stability of the refractory material transportation process.

[0032] The frame-shaped mobile body 10 of the present application can provide sufficient installation area for the electric hoist crane 20 and can provide sufficient structural strength, so that the electric hoist crane 20 can adopt a larger lifting capacity. For example, the maximum lifting weight of the electric hoist crane 20 is 5t, which is significantly larger than the 2t lifting capacity in the prior art, which is beneficial to improving the transportation capacity and transportation efficiency.

[0033] The bracket 11 can be movably arranged relative to the coal car track 1 through a sliding member or a rolling member thereon. In some embodiments, the bracket 11 can be slidably connected to the coal car track 1 through a sliding block. In other embodiments, at least two running wheels 15 that can move along the coal car track 1 are provided at the bottom of each bracket 11, and the running wheels 15 guide the bracket 11 to move along the coal car track 1. At least two running wheels 15 can be arranged at opposite ends of the bottom of the bracket 11, so as to effectively and stably guide the movement of the bracket 11.

[0034] Similarly, the electric hoist 20 can be movably arranged on the running track 12 through a movable bracket. The movable bracket can move along the running track 12 through a sliding member or a rolling member thereon, and the electric hoist 20 is fixedly connected to the movable bracket, so as to move along the running track 12 with the movable bracket. For example, the movable bracket is slidably connected to the running track 12 through a slider, or a running wheel that can move along the running track 12 is provided at the bottom of the movable bracket, and the movable bracket is guided to move along the running track 12 through the running wheel.

[0035] Figure 4 A schematic diagram showing a bracket according to an embodiment of the utility model is shown, referring to Figure 4 In some embodiments, the support 11 is a door-shaped frame, the shape of the door-shaped frame is a trapezoid, the running track 12 is arranged at the upper bottom of the trapezoid, and at least two running wheels 15 are arranged at opposite ends of the lower bottom of the trapezoid. The trapezoidal structure can improve the stability of the support 11. The shape of the door-shaped frame can be roughly an isosceles trapezoid to ensure the symmetry of the structure.

[0036] refer to Figure 4 In some embodiments, the size a of the upper base of the trapezoid is 0.8-1.2 m, the size b of the lower base is 2-3 m, and the size h of the height is 3-4 m. For example, the size a of the upper base of the trapezoid is 1 m, the size b of the lower base is 2.5 m, and the size h of the height is 3.5 m. Ensure that the bracket 11 has sufficient strength and stability.

[0037] In some embodiments, each bracket 11 is provided with a running motor 17 for driving at least two running wheels 15 thereon, and the refractory material transport device 100 further comprises the same controller for controlling the two running motors 17 of the two brackets 11. The two running motors 17 can be controlled to run synchronously by the same controller, thereby controlling the synchronous movement of the multiple running wheels 15 of the two brackets 11. The controller is in communication connection with the running motor 17 and can control the rotation direction, rotation speed, start, pause, etc. of the running motor 17 to move the bracket 11 to a predetermined position along a predetermined direction at a predetermined speed.

[0038] In some embodiments, each running motor 17 is disposed at the bottom of each bracket 11 to lower the center of gravity and ensure the stability of the bracket 11. Figure 4 The traveling motor 17 can be arranged on the upper side of the lower bottom of the trapezoid to avoid interference with the traveling wheel 15 and the coal car track 1.

[0039] In some embodiments, the length of the running track 12 is the same as the length of the coke carbonization chamber, ensuring that the electric hoist 20 can move in a wider range in the horizontal direction to transport the refractory material to the required location.

[0040] In some embodiments, both ends of the running track 12 are provided with stoppers to prevent the electric hoist 20 from derailing. The stoppers limit the moving stroke of the electric hoist 20 to prevent it from falling off due to excessive running. The stoppers can be convexly arranged on the surface of the running track 12 to achieve a limiting effect. The stoppers can be integrally formed with the running track 12, or fixed to the running track 12 by welding, bonding, etc., and can also be detachably arranged on the running track 12 by threaded connection, clamping, etc.

[0041] In some implementations, the length of the transverse member 13 is adjustable in the transverse direction, so that the distance between the two brackets 11 is adjustable, so that the mobile body 10 can move on the coal car track 1 with different spacings, thereby improving the flexibility and adaptability of the transportation device 100. Accordingly, the length of the running track 12 is adjustable in the transverse direction to adapt to coke ovens with different transverse sizes and meet the transportation needs in the transverse direction. The transverse member 13 may include a first transverse portion and a second transverse portion, and the second transverse portion is slidably connected to the first transverse portion, so as to achieve the adjustable length of the transverse member 13 in the transverse direction. Alternatively, the transverse member 13 may include a plurality of detachably connected transverse portions, and the transverse length of the transverse member 13 can be changed by assembling different numbers of transverse portions. The running track 12 can also achieve the adjustable length in the transverse direction in a similar manner.

[0042] In summary, the utility model designs a movable refractory material transportation device on the coal car track on the top of the coke oven. The device is provided with a movable electric hoist. The electric hoist can move along the coal car track in the longitudinal direction of the coke oven following the gantry frame, and can also move in the transverse direction along the running track on the gantry frame. The electric hoist of the refractory material transportation device of the utility model has a large lifting capacity and a stronger transportation capacity than the fixed hoist provided on the coal car in the prior art. It also has the function of moving longitudinally along the coal car track to any carbonization chamber of the coke oven and the function of transverse movement, which can greatly enhance flexibility and improve transportation efficiency. The device has the characteristics of strong transportation capacity, flexible lifting and hanging, etc., has little impact on production, can shorten the maintenance period, and has a good on-site application effect.
