Description

Technical Field

[0001] The present invention relates to the technical field of sintered red brick processing equipment, and particularly to a red brick stack compressor. Background Art

[0002] For the sintered red bricks, whether directly loaded onto trucks or packed and taken out of the kiln, the brick stacks baked on the empty rack need to be changed from the empty rack code to a dense stack code. Only by reducing the volume and occupying less space can it be beneficial for transportation. Fan Zhiyao invented a red brick packing device, with the application number 202110021539.5. However, due to the multiple processes: it requires processes such as stack transfer, stack removal and transfer, two reorganizations, stacking, and packing, and multiple devices: it requires the use of two main machines, three robots, two brick dividing machines, and packing equipment, so it occupies a large area and has a too high cost. Therefore, it is very difficult to promote. Currently, the brick factories still mainly rely on manual labor for loading the bricks out of the kiln. The workload of manual loading is very large, with high physical requirements, and it is becoming increasingly difficult to recruit workers. Summary of the Invention

[0003] The purpose of the present invention is to provide a red brick stack compressor to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution. A red brick stack compressor includes: multiple layers of compression frames, an outer frame, an inner frame, a lifting mechanism, a traveling mechanism, and a pallet. The four small stacks of red bricks baked on the empty rack and distributed in a cross shape are each sleeved into a layer of compression frame corresponding to each layer. In the order from top to bottom, layer by layer, the red bricks in the left and right frames separated by the middle beam of the compression frame are compressed and pressed tightly in opposite directions and lifted. After completion, they travel to the pallet and place the brick stack, withdraw from the compression frame, and then travel to the brick stack to be compressed.

[0005] Further, the compression frame is a square frame, the square frame is provided with a middle beam, the middle beam is in the middle of the square frame, the two ends of the middle beam are connected to the front and rear frame beams of the square frame, the middle beam divides the square frame into left and right two rectangular frames, the upper surface of the middle beam is arc-shaped, the lower surface is pointed, with the point downward, the middle beam is provided with left and right sliding grooves and left and right limiting camshafts for the push-pull plate to slide, the limiting camshaft can rotate 90 degrees under the drive of an external force, and the position of the middle beam when compressing the red bricks is flush with the red bricks of this layer and parallel to the rectangle of the upper layer of red bricks.

[0006] Further, push-pull plates are arranged in the left and right two rectangular frames separated by the middle beam of the compression frame. The push-pull plates are driven by an external force to slide on the frame beams. In one rectangular frame, the push-pull plate is a push plate that pushes the red bricks forward, and in the other rectangular frame, the push-pull plate is a pull plate that pulls the red bricks backward. The movement directions of the push-pull plates are opposite. The push-pull plates compress and press tightly the two brick stacks in each rectangular frame into a square shape.

[0007] Furthermore, devices for lifting and lowering driven by external forces are provided around the compression frame. The devices for lifting and lowering carried on the outer frame can adjust the height of the compression frame up and down to correct it. After the compression frame compresses and presses a layer of red bricks, the compression frame together with the red bricks held tightly in the frame rises on the outer frame to separate from the lower layer, facilitating the compression of the lower-layer red bricks.

[0008] Furthermore, a traveling mechanism is provided on the inner frame. The inner frame carries the outer frame, the outer frame carries the compression frame, and the compression frame holds the pressed red bricks. After each layer of red bricks is compressed, pressed, and lifted, the traveling mechanism starts to move.

[0009] Furthermore, a device for lifting the outer frame is provided on the inner frame. After the red brick stack is pressed and held tightly by the compression frame and travels to the pallet, the compression and pressing limit plate returns to its position - placing the red brick stack on the pallet. The inner frame pulls the outer frame together with the compression frame to rise, separate from the red brick stack, travel to the next red brick stack to be compressed, and lower the compression frame.

[0010] Furthermore, the pallet is composed of a movable pallet and a static pallet. The movable pallet and the static pallet are arranged in a staggered front-back manner. When carrying the red brick stack, the arrangement of the movable pallet and the static pallet is the same as that of the red brick stack. After the movable pallet and the static pallet carry the upper red brick stack, the movable pallet arranged at the back carries the red brick stack and moves to a position flush with the static pallet and stops, facilitating the forklift to fork away two stacks of red bricks at the same time.

[0011] Beneficial effects: The red bricks baked by the empty-frame stacking method, after being compressed and densified by the red brick stack compressor, can be directly forked out of the kiln for storage or loaded onto a vehicle by a forklift. This avoids the need for a large amount of manual labor for the heavy work of unloading from the kiln and loading onto the vehicle. It solves the problem that has always troubled red brick factories, which requires a large amount of manual labor for the heavy work of unloading from the kiln and loading onto the vehicle.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figure 3 shown: The red brick stack compressor is composed of a compression system, a compression frame lifting device, an outer frame, an outer frame lifting system, an inner frame, a traveling system, and a pallet mechanism. Now, taking the example of welding a frame with preferably formed steel, applying external force with pneumatic components to compress and press the red bricks, using a motor plus a reducer plus a sprocket chain drive plus a wire rope winch as the outer frame lifting system, and a motor plus a reducer plus a track wheel plus a track as the traveling system, the specific implementation manner will be described.

[0019] Please refer to Figures 1-6 , the present invention provides a technical solution: A red brick stack compressor includes: The compression system is a multi-layer compression frame 3 and the lifting device 15 - 17 of the compression frame 3 on the outer frame, the outer frame 2, the inner frame 1, the lifting mechanism 15 - 17 of the outer frame 2 on the inner frame 1, and the traveling mechanism 18 - 20. Four small stacks of red bricks 22 baked in a hollow frame and arranged in a grid pattern are pulled out. Each layer of red bricks is correspondingly sleeved into a layer of compression frame 3. In the order from top to bottom, layer by layer, the red bricks 22 in the left and right frames separated by the middle beam 306 of the compression frame 3 are compressed and pressed in opposite directions and lifted. After completion, it travels to the pallets 23, 24, puts down the red brick stack 21, withdraws the compression frame 3, and travels to the red brick stack to be compressed.

[0020] The function of the compression system: It is responsible for compressing the red brick stack baked in a hollow frame into a densely stacked red brick stack, and it is the main system of the red brick stack compressor.

[0021] As Figure 4 shown: The components of the compression system: The compression system is composed of a compression frame 3, a compression cylinder 6, a pressing cylinder 5, a limit cylinder 12, a rotary cylinder 4, a lifting cylinder 13, and compression push plates 14, compression pull plates 8, pressing push plates 10, limit push plates 7, limit camshafts 11, etc. connected to the cylinders.

[0022] The compression frame 3 is a square frame: The front beam 301, rear beam 302, left beam 303, right beam 304, tail beam 305, and middle beam 306 of the compression frame 3 are welded by 10# I-beams into the shape as Figure 4 shown. The front beam 301, rear beam 302, left beam 303, and right beam 304 form a square frame.

[0023] The tail beam of the compression frame: The left beam 303 and the right beam 304 extend backward to the length of the compression cylinder 6, and the tail beam 305 is welded. The frame composed of the left beam 303, the right beam 304, and the rear beam 302 of the tail beam 305 is installed in the compression cylinder 13, and the tail of the compression cylinder 13 is fixed. On the tail beam 305, the telescopic shaft of the compression cylinder 13 passes through the rear beam 302 and is respectively fixed on the push plate 10 and the pull plate 8.

[0024] The middle beam of the compression frame: The two ends of the middle beam 306 are respectively welded in the middle of the front beam 301 and the rear beam 305. The left and right slots of the 10# I-beam are installed in the sliding slots of the push plate 10 and the pull plate 8 and the limit camshaft 11. The middle beam 306 divides the square frame into two rectangular frames, and the left and right rectangular frames should be able to enclose two stacks of red bricks separated by the middle beam 306 into a "day" shape.

[0025] The lifting device of the compression frame on the outer frame: On the four sides of the compression frame 3, there are lifting cylinder seat plates 13 welded with steel plates. The lifting cylinder 17 is fixed under the lifting cylinder seat plate 13. The rod head of the lifting cylinder 17 is connected to the steel plate 15 that can be adjusted in height on the outer frame 2, which plays the role of lifting, fixing, and adjusting the compression frame 3. When the lifting cylinder 17 is filled with high-pressure gas, the telescopic rod of the lifting cylinder 17 abuts against the steel plate 15 that can be adjusted up and down on the four sides of the outer frame, driving the compression frame and the red bricks in the frame upward, lifting the already compressed and compacted red bricks 21 away from the lower-layer red bricks 22, facilitating the compression of the lower-layer red bricks 22. The compression function setting: The rear seat of the compression cylinder 6 is fixed on the tail beam 305. The telescopic shaft of the compression cylinder 6 passes through the rear beam 302 and is respectively connected to the push plate 10 and the pull plate 8. The two ends of the push plate 10 and the pull plate 8 slide on the frame beams 303, 304, and 306 of the compression frame. When the compression cylinder 6 is filled with high-pressure gas, the telescopic shaft of the cylinder 6 drives the push plate 10 and the pull plate 8 to move, and the push plate 10 and the pull plate 8 drive the red bricks to move to be dense and compacted when moving.

[0026] The pressing function setting: The pressing cylinders 5 are respectively fixed on the left beam 303 and the right beam 304, and the pressing push plate 10 is fixed on the telescopic shaft head of the pressing cylinder 5. When the pressing cylinder 5 is filled with high-pressure gas, the telescopic shaft of the pressing cylinder 5 pushes the pressing plate 10 to press the red bricks.

[0027] The limiting function setting: The limiting cylinders 12 are respectively fixed on the front beam 301 and the rear beam 302, and the limiting push plate 7 is fixed on the telescopic shaft head of the limiting cylinder 12. When the limiting cylinder 12 is filled with high-pressure gas, the telescopic shaft of the limiting cylinder 12 drives the limiting push plate 7 to extend to a predetermined position to block the red bricks 21, preventing the red bricks 21 from sticking to the compression frame 3, facilitating the compression frame 3 to withdraw from the compressed red brick stack 21 after completing the compression and compaction task.

[0028] The rotating cylinder 4 is fixed on the front beam 301, and a camshaft 11 is fixed to the rotating rod head of the rotating cylinder 4. When the cylinder is filled with high-pressure gas, the rotating rod head of the rotating cylinder 4 drives the camshaft 11 to rotate 90 degrees. The convex surface of the cam faces outward to block the red bricks so that the red bricks do not stick to the middle beam 306 of the compression frame. After the compression and pressing task is completed, the cam 11 rotates back 90 degrees, with the convex surface of the cam facing downwards, leaving an active space to facilitate the withdrawal of the compression frame 3 from the compressed red brick stack 21.

[0029] Preparation work: The compression frame 3 is sleeved from top to bottom into four small stacks of red brick stacks 22 that are pulled empty and roasted in a cross-shaped pattern. The middle beam 306 cuts into the middle seam of the brick stack. The two rectangular frames on the left and right of the middle beam 306 are each sleeved into two small stacks of red bricks 22 in a Japanese character shape. The middle beam 306 is parallel to the rectangle of the upper-layer red bricks, and the middle beam 306 is flush with the red bricks of this layer.

[0030] The compression, pressing, and lifting process: The compression cylinder 13, the limit cylinder 28, and the rotating cylinder 29 are simultaneously filled with high-pressure gas. The compression cylinder 13 drives the push plate 22 and the pull plate 24 to move together with the red bricks to be compacted and pressed. At the same time, the limit cylinder 28 drives the limit plate 23 to move to a predetermined position to block the red bricks. At the same time, the rotating cylinder 29 drives the camshaft 27 to rotate 90 degrees, with the convex surface facing outward to block the red bricks. After the compression is completed, the pressing cylinder 12 is filled with high-pressure gas, and the telescopic rod of the pressing cylinder 12 pushes the pressing plate to press the red bricks. After the red bricks are compressed and pressed on all four sides, the lifting cylinder 15 is filled with high-pressure gas to drive the compression frame and the red bricks in the frame to rise, disengaging from the lower-layer red bricks.

[0031] Layer-by-layer compression: After the upper-layer red bricks are compressed and pressed, the compression and pressing of the next layer of red bricks are then carried out layer by layer until all layers of this stack of red bricks are completely compressed and pressed.

[0032] The compression frame lifting system: The compression frame lifting system is responsible for lifting the red bricks that have been compressed and pressed in one layer in the compression frame 3 away from the lower layer to facilitate the compression and pressing of the lower-layer red bricks. As Figure 3 shown, the compression frame lifting system is composed of a lifting cylinder seat plate 13, a lifting cylinder 17, an adjustable steel plate 15, and a double lead screw 16.

[0033] The working principle of the compression frame lifting system: The double lead screw 16 is fixed on the outer frame column 2. Two holes of the adjustable steel plate 15 are respectively passed through the double lead screw 16. There is a screw nut on each of the upper and lower sides of the two holes of the steel plate 15 to clamp the steel plate 15. Adjust the screw nut to an appropriate position and lock the screw nut to fix the steel plate. Another hole of the steel plate 15 is connected to the rod head of the lifting cylinder 17, and the tail of the lifting cylinder 17 is fixed on the lifting cylinder seat plate 13 of the compression frame 3. When the lifting cylinder 17 is filled with high-pressure gas, the compression frame 3 is lifted up; when the high-pressure gas is released, the compression frame 3 drops down.

[0034] The outer frame: The outer frame 2 is responsible for connecting all compression frames 3 into a whole, and driven by the lifting system, drives all compression frames 3 to be inserted into and exit the red brick pile.

[0035] like Figure 3 As shown, the outer frame 2 is welded by square tubes into a four-column and four-beam cube, and the four-column square tubes of the outer frame 2 are sleeved inside. The four columns of the outer frame 2 can slide outside the four columns of the inner frame 1. Double screws 16 are fixed to the four column square tubes of the outer frame 2, and steel plates 15 are fixed to the double screws 16. The steel plates 15 are connected to the lifting cylinders 17, and the lifting cylinders 17 are fixed to the lifting cylinder seat plates 13 of the compression frames 3. Each layer of the compression frames 3 corresponds to a set of steel plates 15 and lifting cylinders 17, so all the compression frames 3 are carried on the outer frame 2.

[0036] The working principle of the outer frame 2 is as follows: the outer frame 2 stays on the foot beam of the inner frame 1, and after the compression frame 3 releases the compression plate, the clamping plate and the limit plate of each layer and places the red brick pile on the pallet, the steel wire rope 206 of the outer frame lifting system on the top of the inner frame 1 suspends the outer frame 2 and the outer frame 2 rises together with the compression frame 3. After the outer frame 2 rises above the top of the compressed red brick pile, the walking system walks to the top of the next red brick pile. After the position is calibrated, the steel wire rope of the outer frame lifting system suspends the outer frame 2 and the compression frame 3 together and descends, and the compression frame 3 is put on the outside of the next red brick pile to be compressed to carry out the next compression action.

[0037] The external frame lifting system: The external frame lifting system is responsible for the lifting operation of the external frame 2 together with the compression frame 3.

[0038] like Figure 3 As shown, a cycloidal pinwheel reducer 201 is fixed on the top of the inner frame 1, and a sprocket 202 is fixed on the output shaft of the cycloidal pinwheel reducer 201. The sprocket 202 is transmitted to the sprocket 202 of the transmission shaft 203 through a chain. Bearings and a wire rope winch 204 are fixed at both ends of the transmission shaft 203. The bearings are installed in a bearing seat 205 fixed on the inner frame 1, and the other end of the wire rope 206 of the wire rope winch 204 is fixed on the beam of the outer frame 2.

[0039] Working principle of the external frame lifting system: When the external frame 2 needs to be lifted, the motor of the cycloidal pinwheel speed reducer 201 is powered on and rotates clockwise. The rotation of the motor is decelerated by the cycloidal pinwheel speed reducer 201 to increase the torque. The sprocket 202 fixed on the output shaft of the cycloidal pinwheel speed reducer 201 rotates accordingly. The sprocket 202 drives the sprocket on the transmission shaft 203 through a chain, causing the transmission shaft 203 to rotate together. The rotation of the transmission shaft 203 drives the wire rope winch 204 to rotate. The wire rope winch 204 rotates to wind up the wire rope, and the wound wire rope pulls up the external frame 2 for lifting. When the external frame 2 needs to be lowered, the motor of the cycloidal pinwheel speed reducer 201 is powered on and rotates counterclockwise. Through the above transmission method, the external frame 2 is lowered.

[0040] As Figure 3 shown, the inner frame 1 is welded into a cube with four columns and four beams made of square tubes. The external frame lifting system is fixed on the top of the inner frame 1. The four columns of the inner frame 1 are sleeved with the external frame 2, and the traveling system is fixed on the beams of the inner frame 1.

[0041] The traveling system: The traveling system is responsible for moving the red brick stack compressor from the already compressed red brick stack to the next red brick stack to be compressed.

[0042] As Figure 3 shown, the traveling end beam is fixed under the inner frame 1. The traveling track wheels 18 are installed inside the traveling end beam and are driven by the traveling three-in-one motor 19. The traveling three-in-one motor 19 is integrated with the motor and the speed reducer.

[0043] The working principle of the traveling system is: When traveling is required, the three-in-one motor 19 is powered on and rotates. The output gear of the three-in-one motor 19 meshes with the gear of the traveling track wheel 18. The gear of the traveling track wheel 18 drives the track wheels together to rotate on the track 20, driving the red brick stack compressor to travel.

[0044] The pallet is composed of a moving pallet 23, a static pallet 24, and rollers 25, and is arranged in a staggered front-back manner. When receiving the red brick stack, the moving and static pallets are arranged in the same way as the red brick stack. After the pallet bears the red brick stack, the moving pallet 23 at the back bears the red brick stack 21 and moves on the rollers 25 to a position flush with the static pallet 24 and stops, facilitating the forklift to fork away two stacks of red bricks at the same time.
