Description

Technical Field

[0001] This utility model relates to the field of refractory brick blank technology, and in particular to a lifting device for pressing refractory brick blanks. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory materials made from refractory clay or other refractory raw materials. They are pale yellow or brownish in color. Primarily used for lining smelting furnaces, they can withstand high temperatures of 1580℃–1770℃.

[0003] In the prior art, before refractory bricks are fired, brick powder needs to be pressed into brick blanks using a molding machine. As shown in the brick blank molding machine disclosed in CN102241049B, the core of the molding machine is the molding mold, which is generally composed of a mold base plate, a pressure head, two side plates and two end plates. After brick powder is filled into the mold cavity, the pressure head is pressed down by a hydraulic press to compact the soft brick powder according to the shape of the cavity to form a brick blank. Then, through a lifting mechanism, the base plate is connected to the brick blank and lifted up to push the brick blank out of the mold. After that, the brick blank is transferred and unloaded.

[0004] Traditionally, a lifting mechanism is used to lift the base plate and the brick blank together. After the brick blank is pushed out of the mold, it needs to be transferred and unloaded. However, the existing method of transferring the brick blank from the forming mold is mostly done by manual lifting. The brick blank and the mold base plate are lifted out of the hydraulic press together, and then the bottom is unloaded, which is time-consuming and labor-intensive.

[0005] Therefore, it is necessary to provide a lifting device for pressing refractory brick blanks to solve the above-mentioned technical problems. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] refer to Figures 1 to 5 This utility model provides a lifting device for pressing refractory brick blanks, comprising: a support base 1, the top of which is connected to the fixed end of a lifting cylinder; a first moving groove 2 and a second moving groove 19 respectively provided at both ends of the top of the support base 1; a first slide rail 3 and a second slide rail 20 respectively installed inside the first moving groove 2 and the second moving groove 19; the first slide rail 3 and the slide rail 20 respectively connected to the bottom of a retractable first support plate 4 and a second support plate 9 via sliders; the sides of the first support plate 4 and the second support plate 9 respectively rotatably connected to the middle of a first rotating shaft and a second rotating shaft; one end of the first rotating shaft and the second rotating shaft respectively connected to a first rotating plate 21 and a second rotating plate 20. The first rotating plate 21 and the second rotating plate 10 are respectively connected to the fixed ends of the first cylinder 7 and the second cylinder 11. The telescopic ends of the first cylinder 7 and the second cylinder 11 are respectively connected to the sides of the first clamping plate 8 and the second clamping plate 12. The other ends of the first rotating shaft and the second rotating shaft pass through one side of the first support plate 4 and the second support plate 9 and are respectively connected to the driving ends of the first motor 5 and the second motor 22. The first motor 5 and the second motor 22 are respectively set on the top of the first motor plate 6 and the second motor plate 23. The sides of the first motor plate 6 and the second motor plate 23 are respectively connected to the other side of the first support plate 4 and the second support plate 9.

[0018] In the embodiments of this utility model, reference is made to Figure 2As shown, the first support plate 4 and the second support plate 9 have the same structure. The first support plate 4 includes a fixed plate 24. The top of the fixed plate 24 is provided with a moving groove. The moving groove is slidably connected to the moving plate 25. The inner wall of the moving groove is provided with an external connecting hole. The side of the moving plate 25 is provided with a plurality of internal connecting holes 26. The external connecting holes and the internal connecting holes 26 are connected by bolts 27.

[0019] It should be noted that: by using different mold cavities and base plates, the heights of the first support plate 4 and the second support plate 9 are adjusted. After the adjustment is completed, the inner connecting hole 26 is connected to the outer connecting hole by bolt 27 to fix the height of the first support plate 4 and the second support plate 9. The first slide rail 3 and the second slide rail 20 are existing electric slide rails.

[0020] During the lifting process, the base plate can be lifted by extending and retracting the lifting cylinder. After the base plate is lifted to the outside of the mold cavity, the movement of the first slide rail 3 and the second slide rail 20 drives the first support plate 4 and the second support plate 9 to move to both sides of the base plate. Then, the extension and retraction of the first cylinder 7 and the second cylinder 11 drives the first clamping plate 8 and the second clamping plate 12 to move towards each other until the first clamping plate 8 and the second clamping plate 12 contact the sides of the base plate respectively, thus achieving the lifting of the base plate. After the plates are clamped, the first support plate 4 and the second support plate 9 are moved to one side of the mold cavity by the drive of the first slide rail 3 and the second slide rail 20. The first clamping plate 8 and the second clamping plate 12 are rotated by the drive of the first motor 5 and the second motor 22, which in turn rotates the bottom plate clamped therein. The bottom plate is rotated until the top of the bottom plate is facing downward. Under the action of gravity, the brick blank on the displacement bottom plate is separated from the bottom plate, realizing the bottom unloading operation. The whole process is fully automatic and does not require additional manpower, thus improving the bottom unloading efficiency.

[0021] In the embodiments of this utility model, reference is made to Figure 1 As shown, the top of the support base 1 on one side of the lifting cylinder is connected to the fixed end of the support cylinder 13, and the telescopic end of the support cylinder 13 is connected to the top of the placement plate 14.

[0022] In the embodiments of this utility model, reference is made to Figure 2 As shown, the top two ends of the placement plate 14 are vertically connected to the first baffle 28 and the second baffle 29, respectively.

[0023] It should be noted that by setting up a liftable placement plate 14, when unloading the bottom, the placement plate 14 can be raised to below the position when the bottom plate rotates, so as to receive the falling brick blanks and prevent them from falling directly onto the support base 1. If the height is too high, it will cause damage to the brick blanks. The first baffle 28 and the second baffle 29 can protect the top edge of the placement plate 14 to prevent the brick blanks from falling from the edge of the placement plate 14 when receiving the brick blanks, thus preventing damage to the brick blanks.

[0024] In the embodiments of this utility model, reference is made to Figure 1 As shown, a cushioning pad 15 is bonded to the top of the placement plate 14, and the cushioning pad 15 is made of rubber.

[0025] It should be noted that by setting the buffer pad 15, the impact force on the brick blank when it falls can be reduced, and the brick blank can be prevented from being damaged due to excessive impact force when it falls.

[0026] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the two sides of the placement plate 14 are respectively connected to an L-shaped first guide block and a second guide block. One end of the horizontal part of the first guide block and the second guide block is slidably connected to the first guide groove 31 and the second guide groove 17, respectively. The first guide groove 31 and the second guide groove 17 are respectively arranged on the opposite sides of the first guide plate 32 and the second guide plate 18. The bottom of the first guide plate 32 and the second guide plate 18 are respectively connected to the two ends of the top of the support base 1.

[0027] It should be noted that by setting the first guide block and the second guide block, and by limiting the first guide groove 31 and the second guide groove 17, the stability of the placement plate 14 when moving up and down is improved.

[0028] In the embodiments of this utility model, reference is made to Figure 3 , Figure 4 , Figure 5 As shown, the first rotating plate 21 has a first rotating ring 33 on its side, the first rotating ring 33 is rotatably connected to a first rotating groove 35, the first rotating groove 35 is located on the side of the first support plate 4, the second rotating plate 10 has a second rotating ring 34 on its side, the second rotating ring 34 is rotatably connected to a second rotating groove 36, the second rotating groove 36 is located on the side of the second support plate 9.

[0029] It should be noted that by setting the first rotating ring 33 and the first rotating groove 35, and the second rotating ring 34 and the second rotating groove 36, the stability of the first rotating plate 21 and the second rotating plate 10 during rotation can be improved by limiting the first rotating groove 35 and the second rotating groove 36.

[0030] The working principle of the jacking device for pressing refractory brick blanks provided by this utility model is as follows: After the base plate is lifted to the outside of the mold cavity, the movement of the first slide rail 3 and the second slide rail 20 drives the first support plate 4 and the second support plate 9 to move to both sides of the base plate. Then, the extension and retraction of the first cylinder 7 and the second cylinder 11 drives the first clamping plate 8 and the second clamping plate 12 to move towards each other until the first clamping plate 8 and the second clamping plate 12 contact the sides of the base plate respectively, thus clamping the base plate. After clamping, the first support plate 4 and the second support plate 9 are moved to one side of the mold cavity by the drive of the first slide rail 3 and the second slide rail 20. The first clamping plate 8 and the second clamping plate 12 are rotated by the drive of the first motor 5 and the second motor 22, which in turn drives the base plate clamped in it to rotate, rotating it until the top of the base plate is facing downwards. Under the action of gravity, the brick blank on the displacement base plate is separated from the base plate, realizing the bottom unloading operation.

[0031] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
