Description

Technical Field

[0001] This utility model relates to the technical field of brick stack dismantling equipment, and in particular to a segmented pallet dismantling device. Background Technology

[0002] In the sintering process of brick making (including refractory bricks, building bricks, etc.), a large number of brick blanks need to be stacked into several multi-layered stacks with different gaps and arranged in a longitudinal and transverse manner according to parameters such as ventilation, firing, and temperature distribution before sintering. After the stacks are formed, they are put into a tunnel kiln for firing. After firing, the kiln cars transport the sintered brick stacks to a designated location for dismantling.

[0003] While automated brick-retrieving equipment is widely used in the industry, the mechanical mechanisms and gripping logic of the brick-retrieving grippers still have limitations. On the one hand, traditional brick-retrieving grippers often use a fixed-space design, making it difficult to adapt to the varying widths of brick stacks of different sizes. This leads to frequent problems such as misalignment and brick damage during stack removal, severely restricting operational efficiency. On the other hand, existing equipment has low versatility in its brick-retrieving grippers. For different brick types, frequent manual replacement of specialized gripper structures is required, significantly increasing the labor intensity of workers and causing frequent production line downtime, thus reducing overall enterprise production efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a segmented pallet destacking device. It is reasonably designed, easy to use, applicable to all brick types, does not require frequent replacement of grippers, and improves production efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a segmental pallet destacking device, including a pallet, a lever plate and a hook plate. The lever plate is located above the pallet. The pallet is provided with a first driving device that drives the lever plate to slide relative to the pallet. The hook plate is located at the front end of the pallet. The hook plate is connected to a connecting arm. The connecting arm is provided with a second driving device that drives the hook plate to reciprocate.

[0006] Furthermore, the first driving device is a motor driving device, including a motor and a mechanical transmission mechanism, and the dial is connected to the mechanical transmission mechanism.

[0007] Furthermore, a connecting rod is provided on the side of the pallet, and a first sleeve is sleeved on the outside of the connecting rod. Both ends of the lever are connected to the first sleeve, and the lever is connected to the mechanical transmission mechanism through the first sleeve.

[0008] Furthermore, the pallet is connected to the rack or frame via a lifting mechanism.

[0009] Furthermore, the edge of the tray is provided with a guard plate, which can increase the rigidity of the tray on the one hand, and facilitate the reciprocating sliding of the lever on the other hand.

[0010] Furthermore, the pallet is provided with a sub-plate, the end of which extends outside the pallet and is perpendicular to the hook plate.

[0011] Furthermore, the second driving device includes a third driving device and a fourth driving device. The output end of the third driving device is provided with a second sleeve that is sleeved outside the connecting arm, and the fourth driving device is connected to the connecting arm.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.

Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-5As shown, a segmented pallet destacking device of this embodiment includes a pallet 1, a lever 2, and a hook plate 3. The lever 2 is located above the pallet 1 and is slidably connected to the pallet 1, meaning that the lever 2 and the pallet 1 can slide relative to each other. The pallet 1 is provided with a first driving device 4 for driving the lever 2 to slide relative to the pallet 1. The first driving device 4 can be hydraulically driven, pneumatically driven, electrically driven, linearly driven, mechanically driven, etc., to drive the lever 2 to slide relative to the pallet 1. The hook plate 3 is located at the front end of the pallet 1, that is, outside the loading end of the pallet 1. The length of the hook plate 3 is less than the width of the pallet 1. The hook plate 3 is connected to a connecting arm 5. The connecting arm 5 is equipped with a second driving device 6 that drives the hook plate 3 to move back and forth. That is, after the hook plate 3 grabs the top layer of bricks in a row of stacks, the second driving device 6 drives the hook plate 3 to move towards the pallet 1. The pallet 1 moves the row of bricks towards the pallet 1, and the top layer of bricks in a row of stacks is grabbed onto the pallet 1. Then the pallet 1 moves to the next adjacent row of stacks. Driven by the second driving device 6, the hook plate 3 extends into the gap between the two adjacent rows of stacks and repeats the process of grabbing bricks, grabbing the top layer of bricks in the next row of stacks onto the pallet 1, and so on.

[0026] The first driving device 4 is a motor driving device, including a motor and a mechanical transmission mechanism. The mechanical transmission mechanism can be a lead screw, a driving wheel, a driven wheel, a belt mechanism, a gear and rack mechanism, a driving wheel, a driven wheel, a chain mechanism, etc. The motor is such as a servo motor. The servo motor drives the worm gear reducer to rotate, thereby driving the driving wheels at both ends of the support plate 1 to rotate. The driving wheels rotate through the belt or chain, causing the driving wheel, driven wheel and chain in the transmission structure to rotate. The two ends of the lever plate 2 are connected to the chain, so the lever plate 2 moves synchronously with the chain, realizing the relative sliding between the lever plate 2 and the support plate 1.

[0027] Preferably, the mechanical transmission mechanism is a drive wheel, a driven wheel, a belt or chain mechanism, and a connecting rod 7 is provided on the side of the support plate 1. A first sleeve 8 is sleeved on the outside of the connecting rod 7. Both ends of the lever plate 2 are connected to the first sleeve 8. The lever plate 2 is connected to the belt or chain in the mechanical transmission mechanism through the first sleeve 8.

[0028] The pallet 1 is connected to the frame or machine frame via a lifting mechanism. The lifting mechanism can be one or a combination of existing hydraulic lifting mechanisms, pneumatic lifting mechanisms, electric screw lifting mechanisms, scissor lifting mechanisms, and guide rail lifting mechanisms. The lifting mechanism is not an improvement of this application and is not shown in the accompanying drawings. After the hook plate 3 disassembles and unloads the bricks of the top layer on the kiln car, the lifting mechanism raises and lowers the pallet 1, making it convenient for the hook plate 3 to pull the remaining bricks of the top layer of the stack on the kiln car onto the pallet 1 for disassembly.

[0029] The support plate 1 is provided with a guard plate 9 at its edge. On the one hand, the guard plate 9 can increase the rigidity of the support plate 1, and on the other hand, it is convenient to set up the first driving device to drive the reciprocating sliding of the lever 2. The length of the hook plate 3 is less than the distance between the inner sides of the guard plates 9, so that the hook plate 3 can easily pull the bricks onto the support plate 1.

[0030] The pallet 1 is provided with a secondary plate 10. The end of the secondary plate 10 extends outside the pallet 1. The secondary plate 10 is perpendicular to the hook plate 3, that is, one end of the secondary plate 10 extends beyond the pallet 1 and is located outside the pallet 1. The purpose is that when the hook plate 3 grabs the top layer of bricks in a row or column, the secondary plate 10 can extend into the gap between the brick stacks in that row or column to prevent the top layer or the second layer of bricks from tilting or falling over.

[0031] The second driving device 6 includes a third driving device 61 and a fourth driving device 62. The output end of the third driving device 61 is provided with a second sleeve 63 that is sleeved on the outside of the connecting arm 5, driving the connecting arm 5 to move up and down. The fourth driving device 62 is connected to the connecting arm 5, driving the connecting arm 5 to move back and forth. Preferably, the third driving device 61 and the fourth driving device 62 are cylinder driven or hydraulic driven, which facilitates driving and controlling the movement trajectory of the connecting arm 5 and the hook plate 3. Thus, under the joint action of the third driving device 61, the fourth driving device 62 and the connecting arm 5, the hook plate 3 can be inserted into the gap at the front end of the brick to be removed, remove the row of bricks into the support plate 1, and then return to the state of removing bricks in a cyclical process.

[0032] The pallet 1 is equipped with an inclined guide plate 11 at its loading end. When the hook plate 3 removes the top layer of bricks from the previous row, the previous row of bricks has one less brick than the next row to be removed. At this time, the pallet 1 is suspended above the previous row of bricks and does not contact the bricks of the previous row, or only lightly touches the upper layer of bricks of the previous row. The end of the guide plate 11 contacts the lower layer (i.e., the second layer of bricks from the top) of the next row of bricks to be removed, preventing the lower layer of bricks from tipping over when the hook plate 3 moves the top layer of bricks toward the pallet 1. At the same time, it can also guide the movement of the bricks held by the hook plate 3, so that the hook plate 3 can smoothly move the upper layer of bricks to the top of the pallet 1.

[0033] The bottom of the pallet 1 is provided with reinforcing ribs to ensure the rigidity of the pallet 1, thereby ensuring the flatness of the pallet 1.

[0034] The working principle of this utility model is as follows: The pallet 1 moves to the front end of the stack of bricks to be dismantled. The second driving device 6 drives the connecting arm 5 and the hook plate 3 to move, so that the hook plate 3 is placed in the gap at the rear end of the stack (the gap between the stacks). The second driving device 6 drives the connecting arm 5 and the hook plate 3 to move closer to the pallet 1. The hook plate 3 grabs the top layer of bricks in the stack and moves it onto the pallet 1. After the frontmost brick contacts the lever 2 or the bricks on the pallet 1, under the action of the first driving device 4, the lever 2 moves synchronously with the bricks and the hook plate 3 to a certain position, and pulls the bricks onto the pallet 1. Then, the pallet 1 moves to the top of the stack where the bricks were just pulled. The second driving device 6 drives the hook plate 3 to move away from the pallet 1. Under the action of the second driving device 6, the hook plate 3 moves to the gap at the rear end of the next row of stacks to dismantle the next row of bricks. This process is repeated. After the bricks on the kiln car are dismantled, the pallet 1 moves to the next process. The first drive device 4 pushes the bricks on the pallet 1 to move and unload the bricks on the pallet 1 to the platform of the next process. Then the dismantling of the brick stacks on the kiln car continues.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
