Description

Technical Field

[0001] The invention relates to the technical field of brewing, in particular to a heavy-load quick-change joint. Background Art

[0002] With the development of science and technology, more and more large-scale intelligent equipment is used in the liquor brewing industry to replace traditional manual operations. For example, intelligent equipment is used in various process links such as spreading and drying, steaming, cellaring, and mixing bran. These equipment are generally heavy.

[0003] In the intelligent cellaring process, the inventor of this application applied for application number 2019219493672 in 2019 for an intelligent cellaring device, including a crane and a grab, and also a telescopic arm, one end of the telescopic arm is connected to the crane, and the other end is connected to the grab; the telescopic arm includes a first-section arm and a second-section arm arranged in sequence from the outside to the inside, the first-section arm and the second-section arm are movably connected, and the first-section arm is connected to the crane; a telescopic oil cylinder is arranged in the first-section arm, the fixed end of the telescopic oil cylinder is connected to the first-section arm, and the movable end is connected to the second-section arm. At the same time, the inventor of this application also applied for an intelligent suction and sweeping system for cellars with application number 201921948739X, including a crane, a connecting arm, a collection box and at least one cleaning mechanism arranged on the collection box; one end of the connecting arm is connected to the crane, and the other end is connected to the collection box; the cleaning mechanism includes a rotating shaft and a brush arranged on the rotating shaft, and the collection box is provided with a first power mechanism for driving the rotating shaft to rotate.

[0004] From the above, it can be seen that in the intelligent cellaring process, it is necessary to use a grab bucket to grab the mash in the cellar through the crane and the telescopic arm. After the grab bucket grabs the mash, it is necessary to clean the mash that is partially adhered to the inner wall of the cellar. It is necessary to replace the cleaning mechanism and clean the cellar through the cleaning mechanism. The current replacement method is: first remove the grab bucket from the telescopic arm, and then install the cleaning mechanism on the telescopic arm manually. The following problems were encountered during the installation process: First, the grab bucket and the cleaning mechanism are large-scale equipment, weighing more than several hundred kilograms, which is referred to as heavy load in this article. Therefore, the connecting bolts are relatively large and large, which makes it difficult and time-consuming to disassemble, with low efficiency and high labor intensity; Second, the grab bucket and the cleaning mechanism are connected to the telescopic arm by bolts or pins. Due to the poor fine-tuning performance of the crane, the screw holes or pin holes are not easy to align, and the equipment is also heavy and cannot be pushed manually, which makes the installation very inconvenient. Summary of the invention

[0005] The present invention provides a heavy-load quick-change joint to solve the technical problem of high labor intensity and low efficiency in switching connections between heavy loads of the telescopic arm.

[0006] The technical solution adopted by the present invention is: a quick-change joint for heavy loads, comprising a base plate for connecting with a boom and a connecting plate for connecting with a heavy load;

[0007] A pin is provided on the connecting plate, and a concave slot is provided on the side of the pin near the end;

[0008] An upper support and a lower support are stacked on the bottom plate from top to bottom. The upper support is movably connected to the lower support, and the lower support is movably connected to the bottom plate. A through hole matching the pin is provided on the upper support, and a limiting hole connected to the through hole and matching the card slot is provided beside the through hole.

[0009] The bottom plate is provided with a power mechanism for driving the lower support to slide relative to the bottom plate and the upper support, and a limiting plate for limiting the upper support is provided on one side of the lower support away from the power mechanism.

[0010] Fix the connecting plate to the heavy load, and fix the bottom plate to the telescopic arm, so that the connecting plate is horizontal, align the control through hole of the telescopic arm with the pin, and then control the bottom plate to descend to the upper end face of the connecting plate, and the pin passes through the through hole of the upper support; at this time, the power mechanism drives the lower support to move toward the direction of the pin, and the upper support moves synchronously with the lower support. When the limit hole of the upper support reaches the slot of the pin, the connection between the bottom plate and the connecting plate is completed, that is, the connection of the heavy load is completed. Compared with the traditional manual connection, the present invention uses a quick-change joint to enable the telescopic arm to be quickly disassembled and assembled between different heavy loads, without manual operation and without the need for connection through bolts or pins and other connectors, which changes the connection method, reduces labor intensity, and improves production efficiency. In addition, the device has a simple structure and is easy to operate.

[0011] Furthermore, a first sliding mechanism is provided between the upper support and the lower support, including a first sliding block arranged at the bottom of the upper support and a first sliding rail arranged at the top of the lower support and matching with the first sliding block, so as to reduce the friction between the upper support and the lower support, so that the two can slide against each other more smoothly.

[0012] Furthermore, the bottom surface of the upper support and the top surface of the lower support are both inclined surfaces and are parallel to each other. When the upper support and the lower support slide relative to each other, the height of the upper support and the lower support can be adjusted through the inclined surface, thereby completing the automatic clamping of the pin shaft, and further ensuring the stability of the connection between the bottom plate and the connecting plate. The power mechanism drives the lower support to move toward the pin shaft, and the upper support moves synchronously with the lower support. When the limit hole of the upper support reaches the slot of the pin shaft, the motor mechanism continues to push the lower support to move, so that the upper support becomes higher and higher until it hits the top of the slot, and the power mechanism stops working, completing the clamping of the pin shaft.

[0013] Furthermore, a guide shaft is provided on the connecting plate, and a guide hole matching the guide shaft is provided at a corresponding position on the bottom plate. The guide shaft makes it easier to install the connecting plate and the bottom plate, and plays a guiding role.

[0014] Furthermore, there are two guide holes, which are arranged on both sides of the lower support. The two guide shafts further improve the guiding accuracy and also balance the center of gravity of the connecting plate, avoiding the tilting of the device due to gravity eccentricity, which is inconvenient to work.

[0015] Furthermore, the end of the guide shaft is a conical structure, which further increases the guiding range. When the guide shaft and the guide hole are inserted into each other, the cross section of the guide shaft increases from small to large, thus playing an automatic guiding role.

[0016] Furthermore, a second sliding mechanism is provided between the lower support and the bottom plate, including a second sliding block arranged at the bottom of the lower support and a second sliding rail arranged at the top of the bottom plate and matching with the second sliding block, so as to reduce the friction between the lower support and the bottom plate, so that the two can slide against each other more smoothly.

[0017] Furthermore, the power mechanism is an electric cylinder, the fixed end of the electric cylinder is connected to the bottom plate, and the movable end is connected to the lower support. The structure is simple, the drive is stable, and the cost is low.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention uses a quick-change joint to enable the telescopic arm to be quickly disassembled and assembled between different heavy loads, without manual operation and without the need for connection through connecting parts such as bolts or pins, thereby changing the connection method, reducing labor intensity, and improving production efficiency. The device has a simple structure and is easy to operate.

[0020] 2. The bottom surface of the upper support and the top surface of the lower support of the present invention are parallel inclined surfaces. When the upper support and the lower support slide relatively, the height of the upper support and the lower support can be adjusted through the inclined surfaces, thereby completing the automatic clamping of the pin shaft above the upper support, further ensuring the stability of the connection between the bottom plate and the connecting plate.

[0030] The present invention is further described below in conjunction with the accompanying drawings.

[0031] Example:

[0032] like Figure 1 to Figure 6 As shown, the heavy-duty quick-change connector of the present invention comprises a base plate 1 for connecting with a boom and a connecting plate 2 for connecting with a heavy load; a pin shaft 3 is arranged on the connecting plate 2, and a concave slot 31 is arranged on the side of the pin shaft 3 near the end; an upper support 4 and a lower support 5 are stacked from top to bottom on the base plate 1, the upper support 4 is movably connected with the lower support 5, and the lower support 5 is movably connected with the base plate 1, a through hole 41 matching with the pin shaft 3 is arranged on the upper support 4, and a limiting hole 42 connected with the through hole 41 and matching with the slot 31 is arranged beside the through hole 41; a power mechanism for driving the lower support to slide relative to the base plate and the upper support is arranged on the base plate 1, and a limiting plate 51 for limiting the upper support 4 is arranged on the side of the lower support 5 away from the power mechanism. A first sliding mechanism is arranged between the upper support 4 and the lower support 5, including a first slider 61 arranged at the bottom of the upper support 4 and a first slide rail 62 arranged at the top of the lower support 5 and matching with the first slider 61. The bottom surface of the upper support 4 and the top surface of the lower support 5 are both inclined surfaces and parallel to each other. A guide shaft 21 is provided on the connecting plate 2, and a guide hole 11 matching the guide shaft 21 is provided at a corresponding position on the bottom plate 1. There are two guide holes 11, which are respectively arranged on both sides of the lower support 5. The end of the guide shaft 21 is a conical structure. A second sliding mechanism is provided between the lower support 5 and the bottom plate 1, including a second slider 71 arranged at the bottom of the lower support 5 and a second slide rail 72 arranged at the top of the bottom plate 1 and matching the second slider 71. The power mechanism is an electric cylinder 8, the fixed end of the electric cylinder 8 is connected to the bottom plate 1, and the movable end is connected to the lower support 5.

[0033] Working principle: In the intelligent cellar opening process, two connecting plates 2 are made, and the two connecting plates 2 are connected to the grab bucket and the cleaning mechanism respectively by bolt connection; the telescopic arm is connected to the bottom plate 1, and a connecting rod 9 connected to the telescopic arm is provided on the bottom plate 1. When it is necessary to grab the mash in the cellar, the connecting plate connected to the grab bucket is placed horizontally, the telescopic arm controls the through hole of the bottom plate to align with the pin, and then controls the bottom plate to descend to the upper end surface of the connecting plate, and the pin passes through the through hole of the upper support; at this time, the electric cylinder 8 extends to drive the lower support 5 to move toward the pin 3, and the upper support 4 moves synchronously with the lower support 5. When the limiting hole 42 of the upper support 4 reaches the clamping groove 31 of the pin 3, the upper support 4 stops moving in the horizontal direction relative to the pin 3, and the electric cylinder 8 continues to extend to push the lower support 5 to move. The lower support 5 drives the upper support 4 to rise in the vertical direction through the inclined surface, so that the upper support 4 becomes higher and higher until it supports the top of the clamping groove 31, and the electric cylinder 8 stops working to complete the clamping of the pin 3.

[0034] When the mash in the cellar is grabbed and the cleaning mechanism needs to be replaced to clean the cellar, the electric cylinder 8 retracts to drive the lower support 5 to move. During the sliding process between the lower support 5 and the upper support 4, the upper support 5 is driven to descend in the vertical direction through the inclined surface, thereby releasing the clamping action of the pin shaft 3. The electric cylinder 8 continues to retract, and the limit plate 51 on the lower support 5 drives the upper support 4 to move to the right synchronously with the lower support 5. At this time, the pin shaft 3 is located in the through hole 41, and the bottom plate 1 is lifted by the telescopic arm to complete the disassembly of the connecting plate 2 and the bottom plate 1.

[0035] Compared with traditional manual connection, the present invention uses a quick-change joint to enable the telescopic arm to be quickly disassembled and assembled between different heavy loads. There is no need for manual operation and no need to connect through connecting parts such as bolts or pins. This changes the connection method, reduces labor intensity, and improves production efficiency. The device has a simple structure and is easy to operate.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
