DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 4 In an embodiment of the utility model, a refractory material construction lifting platform includes a material platform 1, and at least one mobile platform 2 is slidably equipped in the length direction of the material platform 1, and the mobile platform 2 includes a fixed platform 201, a first folding platform 202 and a second folding platform 203. The fixed platform 201 is slidably connected to the material platform 1, one end of the first folding platform 202 is rotatably connected to the fixed platform 201, and the other end of the first folding platform 202 is rotatably connected to the second folding platform 203; a folding component 3 is provided between the lower end of the mobile platform 2 and the second folding platform 203, which is used to adjust the position relationship of the first folding platform 202 and the second folding platform 203 relative to the fixed platform 201 to meet the size of the unfolding surface of the mobile platform 2 under different working conditions; first slide rails 11 are provided on both sides of the material platform 1, and a first slide seat 12 matched with the first slide rails 11 is installed at the bottom of the fixed platform 201.

[0019] In this embodiment: Since the space occupied by the traditional lifting and hoisting devices is fixed, lifting equipment of different specifications needs to be deployed when building or repairing kilns of different models. Secondly, if the volume of the lifting platform is too small, the staff may not be able to reach the repair area. On the contrary, if the volume of the lifting platform is too large, it may block the area to be repaired, thereby causing interference with the working conditions. In this state, it is extremely inconvenient for the staff to carry out the construction, thereby affecting the work efficiency. Therefore, this solution assembles a mobile platform 2 that can move left and right on the basis of the material platform 1. The mobile platform 2 slides along the length direction of the material platform 1, thereby indirectly expanding the working range. Secondly, the mobile platform 2 is a foldable structure, and the extension area of ​​the mobile platform 2 can be adjusted according to different working conditions to meet the working needs under actual conditions.

[0020] Specifically, the refractory material construction lifting platform mainly includes a material platform 1, a mobile platform 2 and a folding component 3. The material platform 1 is installed on a lifting track, and a lifting motor is used to drive the material platform 1 to move up and down along the lifting track. Refractory materials are placed in the material platform 1, and the mobile platform 2 is installed on the first slide rail 11 on the material platform 1. The mobile platform 2 is driven to move on the first slide rail 11 by an existing linear drive device.

[0021] The mobile platform 2 is composed of a fixed platform 201, a first folding platform 202 and a second folding platform 203, which are connected in a head-to-tail rotational manner in sequence, and the positions of the first folding platform 202 and the second folding platform 203 are adjusted by using a folding component 3. When it is necessary to expand the extension area of ​​the mobile platform 2, the fixed platform 201, the first folding platform 202 and the second folding platform 203 are controlled to be on the same horizontal line by the folding component 3. Conversely, when it is necessary to reduce the area of ​​the mobile platform 2, the second folding platform 203 is controlled to be folded parallel to the first folding platform 202 by the folding component 3, and the first folding platform 202 and the fixed platform 201 are folded vertically.

[0022] Please refer to Figure 4 At least one limiting plate 4 is connected to the bottom of the first folding platform 202, and the limiting plate 4 is fixedly connected to the first folding platform 202 by bolts.

[0023] In this embodiment: when the first folding platform 202 and the fixed platform 201 are in the same horizontal plane, one end of the limit plate 4 will contact the bottom of the fixed platform 201, thereby limiting the first folding platform 202 from folding and rotating downward, and the staff can stand stably on the first folding platform 202.

[0024] Please refer to Figure 3 and Figure 4 Two meshing gears 5 are installed on the outer side of the connection between the first folding platform 202 and the second folding platform 203, and the two gears 5 are installed on the first folding platform 202 and the second folding platform 203 respectively.

[0025] In this embodiment: the first folding platform 202 and the second folding platform 203 are connected to each other by two gears 5, and when the second folding platform 203 is driven to rotate by the folding assembly 3, the meshing gears 5 are used to drive one end of the first folding platform 202 to move upward until the first folding platform 202 and the fixed platform 201 are perpendicular to each other. In addition, when the fixed platform 201, the first folding platform 202 and the second folding platform 203 are all on the same water surface, the first folding platform 202 that cannot rotate downward will also limit the second folding platform 203 corresponding to the first folding platform 202 from rotating downward through the gear 5.

[0026] Please refer to Figure 3 and Figure 4The folding assembly 3 includes a hydraulic cylinder 301, which is fixedly installed at the lower end of the fixed walkway 201. The lower end of the fixed walkway 201 is located on one side of the hydraulic cylinder 301 and is provided with two parallel second slide rails 302. The second slide rail 302 is slidably equipped with a second slide seat 303 in the length direction. The second slide seat 303 is fixedly connected to the output end of the hydraulic cylinder 301. Two symmetrically arranged connecting rods 304 are connected between the second slide seat 303 and the second folding walkway 203. The two ends of the connecting rod 304 are respectively rotatably connected to the second folding walkway 203 and the second slide seat 303 through bearings; the output shaft of the hydraulic cylinder 301 and the second slide rail 302 are on the same horizontal line.

[0027] In this embodiment: when the mobile platform 2 needs to be fully unfolded, the hydraulic cylinder 301 pushes the second slide 303 to slide along the length direction of the second slide rail 302, and the second slide 303 drives the first folding walkway 202 and the second folding walkway 203 to rotate and unfold through the connecting rod 304 until the fixed walkway 201, the first folding walkway 202 and the second folding walkway 203 are all on the same water surface. At this time, the output end of the hydraulic cylinder 301 is the maximum stroke, and the first folding walkway 202 and the second folding walkway 203 are limited by the connecting rod 304, the gear 5 and the limit plate 4, and the staff can stand on the first folding walkway 202 and the second folding walkway 203.

[0028] When the first folding walkway 202 and the second folding walkway 203 need to be stored, the second slide 303 is driven to move in the opposite direction by the hydraulic cylinder 301, and then one end of the second folding walkway 203 is pulled downward by the connecting rod 304, and the other end of the second folding walkway 203 drives one end of the first folding walkway 202 to move upward through the gear 5, until the first folding walkway 202 and the second folding walkway 203 are folded in parallel, and at the same time, the fixed walkway 201 and the first folding walkway 202 are folded vertically.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
