Description

Technical Field

[0001] This utility model belongs to the field of transport vehicle technology, and in particular to a convenient refractory material transport vehicle. Background Technology

[0002] High-temperature refractory bricks are commonly used for insulation, heat insulation, and structural purposes inside high-temperature furnaces. Almost all high-temperature containers and equipment require refractory materials to achieve high-temperature technical conditions and protect the long-term stable operation of the steel structure furnace body.

[0003] Currently, high-temperature refractory bricks need to be stacked on pallets after processing for easy transport or packaging. However, most high-temperature refractory bricks are currently stacked manually, which can lead to uneven stacking and misalignment. Existing refractory material transport vehicles do not have the function of squeezing the refractory bricks neatly or limiting their position. Therefore, if conventional refractory material transport vehicles are used for transport, there is a risk of safety accidents such as refractory bricks tipping over. Therefore, there is an urgent need for a convenient refractory material transport vehicle. Utility Model Content

[0004] The purpose of this invention is to provide a convenient refractory material transport vehicle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient refractory material transport vehicle, comprising a pallet and a back plate. A rectangular hole is laterally opened inside the pallet. A partition is fixedly connected inside the rectangular hole. Slide plates are symmetrically slidably connected inside the rectangular hole. A vertical plate is fixedly connected to one side of each slide plate extending outside the rectangular hole. A bidirectional lead screw is rotatably connected to the partition via a fixed bearing. Threaded holes are opened on the side of each slide plate near the partition. Both ends of the bidirectional lead screw are threaded into the threaded holes, with one threaded hole on one slide plate being through-hole. One end of the bidirectional lead screw is threaded to the outside of the slide plate. Supporting strips are symmetrically arranged below the pallet. A traveling wheel is symmetrically rotatably connected to the lower end of each supporting strip. Multiple hydraulic cylinders are fixedly installed on the top surface of each of the two supporting strips. The telescopic ends of the hydraulic cylinders are fixedly connected to the lower end of the pallet.

[0006] Preferably, a strip groove is symmetrically formed on the upper part of the inner wall of the rectangular hole, and a limit strip is symmetrically and fixedly connected to the top surface of the slide plate.

[0007] Preferably, the two limiting strips fixedly connected to the top surface of the sliding plate are slidably connected to the inside of the two strip grooves opened on the top surface of the inner wall of the rectangular hole.

[0008] Preferably, limit holes are symmetrically provided on the opposite sides of the two slide plates, and limit rods are symmetrically and fixedly connected through the partition plate.

[0009] Preferably, the two ends of the two limiting rods slide into the interior of the limiting holes opened on the sidewalls of the two slide plates.

[0010] Preferably, an arc-shaped plate is fixedly connected to the side of the tray away from the back plate.

[0011] Preferably, wear-resistant pads are fixedly connected to the opposite sides of both vertical plates.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This convenient refractory material transport vehicle, when transferring manually stacked refractory bricks, first rotates a double-ended screw extending to the outside of one of the slide plates. The rotation of the screw drives two slide plates threaded onto its wall to extend through rectangular holes to both sides of the pallet. This pushes the back plate and the pallet towards the stacked refractory bricks until the pallet is inserted under the pallet supporting the stacked refractory bricks. Then, the double-ended screw is rotated in the opposite direction, causing the two slide plates and the vertical plates fixedly connected to them to move towards the stacked refractory bricks above the pallet. When the inner sides of the two vertical plates contact the refractory bricks, the double-ended screw is rotated again, causing the two vertical plates to press and flatten the refractory bricks. Finally, the hydraulic cylinder is activated to lift the pallet and the refractory bricks on it for transfer. Compared to existing technologies, this device prioritizes further pressing of manually stacked refractory bricks to make them more uniform, thus greatly preventing the refractory bricks from tipping over during rotation due to uneven stacking.

[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0022] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0023] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0024] like Figures 1 to 4 This invention relates to a convenient refractory material transport vehicle, comprising a pallet 1 and a back plate 2. The back plate 2 is vertically fixed to one side of the top surface of the pallet 1. An arc-shaped plate 15 is fixedly connected to the side of the pallet 1 away from the back plate 2. The arc surface of the arc plate 15 is set at the top, so that the end of the pallet 1 can be easily inserted into the bottom of the pallet on which refractory bricks are stacked without being stuck by foreign objects at the bottom. A rectangular hole 3 is horizontally opened inside the pallet 1. A partition 4 is fixedly connected inside the rectangular hole 3. The partition 4 is located in the middle of the rectangular hole 3 and its height is the same as that of the rectangular hole 3. Slide plates 5 are symmetrically slidably connected inside the rectangular hole 3. The two slide plates 5 are separated by a partition to prevent them from contacting each other. A vertical plate 6 is fixedly connected to one side of the two slide plates 5 extending outside the rectangular hole 3. Wear-resistant pads 16 are fixedly connected to the opposite side of the two vertical plates 6. Thanks to the wear-resistant pads 16 on the opposite side of the two vertical plates 6, the friction between the inner wall of the vertical plate 6 and the refractory bricks can be effectively reduced, thereby greatly extending the service life of the vertical plate 6.

[0025] A bidirectional lead screw 7 is rotatably connected to the upper part of the partition plate 4 through a fixed bearing. The fixed bearing is fixedly sleeved inside the partition plate 4, thereby enabling the bidirectional lead screw 7 to rotate and be positioned. Threaded holes 8 are opened on the side of each of the two slide plates 5 near the partition plate 4. The two ends of the bidirectional lead screw 7 are threaded into the threaded holes 8, and the threaded hole 8 on one of the slide plates 5 is through-hole. One end of the bidirectional lead screw 7 is threaded to the outside of the slide plate 5. The bidirectional lead screw 7, which rotates in the opposite direction to the outside of one of the slide plates 5, will drive the two slide plates 5 and the vertical plates 6 fixedly connected to the slide plates 5 to move towards the stacked refractory bricks above the tray 1. When the inner sides of the two vertical plates 6 contact the refractory bricks, the bidirectional lead screw 7 continues to rotate, driving the two vertical plates 6 to press the refractory bricks flat. Bearing strips 9 are symmetrically arranged below the tray 1. The lower ends of the bearing strips 9 are symmetrically rotatably connected to traveling wheels 11. Multiple hydraulic cylinders 10 are fixedly installed on the top surface of each of the two bearing strips 9. The telescopic ends of the hydraulic cylinders 10 are fixedly connected to the lower end of the tray 1.

[0026] A strip groove is symmetrically opened on the upper part of the inner wall of the rectangular hole 3. A limiting strip 12 is symmetrically fixedly connected to the top surface of the slide plate 5. The two limiting strips 12 fixedly connected to the top surface of the slide plate 5 are slidably connected to the inside of the two strip grooves opened on the top surface of the inner wall of the rectangular hole 3. Thanks to the setting of the limiting strip 12 and the strip groove, the sliding direction of the slide plate 5 can be effectively limited.

[0027] Each of the two sliding plates 5 has a symmetrically arranged limiting hole 13 on one side opposite to the other. A limiting rod 14 is symmetrically and fixedly connected through the partition plate 4. The two ends of the two limiting rods 14 slide and extend into the limiting hole 13 on the side wall of the two sliding plates 5. Thanks to the setting of multiple limiting rods 14, the sliding direction of the sliding plate 5 can be further controlled, and the sliding of the two sliding plates 5 can be made more stable.

[0028] Working principle

[0029] This convenient refractory material transport vehicle, when in use, first pushes the device next to the refractory bricks to be transported, then rotates the double-ended screw 7 extending to the outside of one of the slide plates 5. The rotation of the double-ended screw 7 causes the two slide plates 5, threaded onto its wall, to slide along the rectangular holes 3 inside the tray 1, and to slide outwards from the rectangular holes 3, extending to both sides of the tray 1. Simultaneously, the slide plates 5 push the vertical plate 6 fixedly connected to them to move. As the two slide plates 5 move along the rectangular holes 3, the limiting strip 12 fixedly connected to the top surface of the slide plates 5 slides along the strip groove inside the rectangular holes 3, and the limiting rod 14 fixedly connected to the partition 4 slides along the limiting holes 13 on the side walls of the two slide plates 5. Thus, the limiting strip 12 and the limiting rod 14 further limit the sliding of the slide plates 5. Subsequently... Push the back plate 2 and the tray 1 towards the stacked refractory bricks until the tray 1 is inserted under the tray holding the refractory bricks. At this point, the back plate 2 will first contact the refractory bricks. Applying a pushing force to the back plate 2 will flatten the unevenly stacked refractory bricks. Since the refractory bricks transported manually will not be stacked too high, they can be easily flattened by manpower. Then, rotate the double-ended screw 7 extending to the outside of one of the slide plates 5 in the opposite direction. The double-ended screw 7 will drive the two slide plates 5 and the vertical plates 6 fixedly connected to the slide plates 5 to move towards the stacked refractory bricks above the tray 1. When the inner sides of the two vertical plates 6 contact the refractory bricks, continue to rotate the double-ended screw 7 to drive the two vertical plates 6 to press the refractory bricks flat. Then, start the hydraulic cylinder 10 to lift the tray 1 and the refractory bricks on the tray and transport them.
