[0025] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0026] For the construction of refractory materials in the furnace, the main method currently used is to use a fixed high platform and a cantilever crane for combined operations. The cantilever crane is mainly used to lift furnace-building equipment and furnace-building materials mixed into a plastic state. The platform allows workers to rise to the tank mouth, and the workers then use safety tools such as lifting ropes to enter the furnace and use furnace-building equipment and furnace-building materials to build the furnace. After the operation is completed, the various equipment must be transported to other locations to avoid affecting the subsequent operations of the furnace. The entire process of building refractory materials in the furnace is time-consuming and inefficient.

[0027] See also Figure 1-Figure 3 In the first aspect of the present application, an embodiment provides a maintenance platform for cold furnace repair operations, including a track 2, a first platform 3, a second platform 4, a transport pipe 5 and a drive mechanism 7.

[0028] The track 2 includes two guide rails respectively arranged on both sides of the furnace mouth 1 of the furnace; the first platform 3 is slidably arranged on the track 2, and an operating port 31 is arranged in the middle of the first platform 3. When the first platform 3 moves to above the furnace mouth 1, the projection of the operating port 31 in the vertical direction at least partially falls within the furnace mouth 1; the second platform 4 is arranged above the first platform 3 through a plurality of support columns 91, and a lifting mechanism 6 is arranged between the second platform 4 and the first platform 3; the inlet of the transport pipe 5 is arranged on the second platform 4, and the outlet of the transport pipe 5 is located above the first platform 3; the driving mechanism 7 drives the first platform 3 to move along the track 2.

[0029] It can be understood that a larger area of ​​working space is provided by the first platform 3. The maintenance platform is moved to the furnace intersection by the driving structure, and the operator can operate the furnace mouth 1 of the furnace around the operating port 31; the second platform 4 is used to place the equipment required for the furnace operation, which is easy to use. For example, the refractory material in the furnace needs to be mixed into a shaped state by a stirring device. The stirring device is set on the second platform 4. The shaped refractory material stirred by the stirring device is transported to the first platform 3 through the transport pipe 5. The operator uses other storage devices to move the refractory material output from the transport pipe 5 for the operator to use, which greatly shortens the time of transporting the refractory material to the furnace and can improve the construction efficiency of the operator. After the construction is completed, the driving mechanism 7 drives the maintenance platform to leave the furnace intersection. There is no need to carry the equipment required for the furnace maintenance multiple times. The preparation and finishing stages of the maintenance can be carried out quickly, and the maintenance efficiency is high.

[0030] In some embodiments, the operation port 31 is disposed in the middle of the first platform 3 , so that the space around the operation port 31 on the first platform 3 is relatively even, making it easier for operators to move on the first platform 3 .

[0031] Taking into account that the furnace mouth 1 of some furnaces is higher than the ground, in some embodiments, one side of the operating port 31 is connected to one side of the first platform 3, that is, the operating port 31 at this time is U-shaped, so as to avoid the furnace mouth 1 of the furnace, so that the driving mechanism 7 can drive the operating port 31 of the first platform 3 close to the furnace mouth 1, thereby improving the adaptability of the maintenance platform to various furnaces.

[0032] Taking into account the heavy weight of the first platform 3, the second platform 4 and the equipment placed on the first platform 3 and the second platform 4, in some embodiments, at least two pairs of rollers 8 that roll with the track 2 are provided at the bottom end of the first platform 3. The rolling friction between the rollers 8 and the track 2 reduces the pressure of the driving mechanism 7, increases the speed at which the driving mechanism 7 drives the maintenance platform to move, and thereby improves the maintenance efficiency.

[0033] In some embodiments, the driving mechanism 7 includes a motor and a transmission box. The motor is connected to the roller 8 through the transmission box. The transmission box is a power transmission device that is commonly used in the field of transmission technology. The motor transmits and adjusts the output power through the transmission box to drive the roller 8 to rotate, thereby allowing the first platform 3 to move on the guide rail. Taking into account the weight of the first platform 3, the second platform 4, and the equipment placed on the second platform 4, in some embodiments, each roller 8 is connected to a driving mechanism 7, and multiple driving mechanisms 7 are used to jointly drive the first platform 3 to move, thereby increasing the speed of movement and thus improving maintenance efficiency. Of course, in other embodiments, only one roller 8 in each pair of rollers 8 may be connected to a driving mechanism 7. At the same time, it is ensured that among the multiple rollers 8 on each guide rail, at least one roller 8 is connected to a driving mechanism 7 to improve the stability of the first platform 3 when moving. For example, please refer to Figure 3 Two pairs of rollers 8 are provided at the bottom of the first platform 3 , wherein one pair of rollers 8 arranged opposite to each other are both connected to the driving structure 7 , while the other pair of rollers 8 arranged opposite to each other are not connected to the driving mechanism.

[0034] In some embodiments, a reinforcement column 92 is further provided between the first platform 3 and the second platform 4. The top end of the reinforcement column 92 is fixedly connected to the bottom end of the first platform 3, and the bottom end of the reinforcement column 92 is fixedly connected to the top end of the second platform 4. The reinforcement column 92 is arranged at an angle. It can be understood that the reinforcement column 92 enhances the structural strength between the first platform 3 and the second platform 4, thereby improving the reliability and safety of the first platform 3 and the second platform 4 during use.

[0035] In some embodiments, the bottom end of the reinforcing column 92 is also fixedly connected to the bottom end of a supporting column 91, further increasing the tightness of the connection between the first platform 3, the second platform 4, the supporting column 91 and the reinforcing column 92. At this time, a triangular structure is formed between the supporting column 91, the reinforcing column 92 and the second platform 4, which is not easy to deform and has high structural strength.

[0036] In some embodiments, fences 93 are provided on the outer edge of the first platform 3, the outer edge of the operating port 31, and the outer edge of the second platform 4. On the one hand, the fence 93 can prevent the equipment on the first platform 3 or the second platform 4 from leaving the platform. On the other hand, the fence 93 can also protect the workers and prevent them from falling from the first platform 3 or the second platform 4.

[0037] In some embodiments, the lifting mechanism 6 is a staircase, allowing workers to move from the first platform 3 to the second platform 4 via the staircase to operate equipment on the second platform 4 or to pick up or place small items. Large equipment can be hoisted to the second platform 4 using an overhead crane before the maintenance platform is put into use. Of course, the lifting mechanism 6 can also be an electric lift, comprising a lifting platform and a drive mechanism 7. Driven by the drive mechanism 7, the lifting platform can be flush with the top surfaces of the first platform 3 and the second platform 4, respectively. Workers or equipment can be raised to the second platform 4 or lowered to the first platform 3 via the electric lift.
