Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a cross chain suspension conveying device and an accumulation type suspension conveying chain system. Background Art

[0002] In modern industrial production, as a highly mechanized integrated space storage, transportation and lifting system, the accumulation type overhead conveyor plays a vital role. The system can not only effectively perform the material transportation task, but also realize the whole process of the production line, perfectly integrating exquisite process operation, efficient storage management and flexible transportation functions. This comprehensive design greatly improves the automation level of the production process and provides strong technical support for scientific management and efficient production. The accumulation type overhead conveyor is widely applicable to a variety of production needs. It can easily and smoothly cooperate with various operating stations, loading and unloading equipment and automated instruments on the production line, significantly improving production efficiency and flexibility.

[0003] However, in the existing accumulation and release overhead conveying equipment, the design of the traction track has become one of the key factors restricting its further performance improvement. The traditional design uses two wheels placed on both sides of the I-rail, and achieves traction through a sliding connection. Although this design meets the basic transportation needs to a certain extent, it exposes a series of problems in actual application. Especially in the traction process, due to the complexity of material transportation, including various dynamic changes such as rising, falling and tilting, it is difficult to maintain uniform force on the two wheels. This uneven force state not only affects the stability of the relative movement between the wheel and the I-rail, but also significantly increases the resistance during traction, reducing the operating efficiency and reliability of the entire system.

[0004] Specifically, the unstable relative movement between the wheel and the I-beam rail not only increases wear and shortens the service life of the equipment, but may also cause vibration and noise, which has an adverse impact on the production environment. At the same time, the increased traction resistance not only consumes more energy, but may also pose a challenge to the stability of the power system and increase the risk of failure.

[0005] Therefore, how to improve the design of traction rails to solve problems such as uneven force, unstable relative motion and large traction resistance has become an important issue that needs to be urgently solved in the current field of power-up and release overhead conveying equipment technology.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The purpose of the present invention is to provide a cross-chain suspended conveying device and an accumulation-type suspended conveying chain system to solve the problems existing in the prior art. By optimizing the layout and connection method of the traveling wheel and the chain guide wheel, it is ensured that under complex and changeable conveying conditions, the traveling wheel in the traction channel and the chain guide wheel in the guide channel can maintain stable operation, effectively reduce the traction resistance, and improve the operation efficiency and reliability.

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] like Figure 1 to Figure 15As shown, the present invention provides a cross chain suspension conveying device, including a traction track 32 and a cross chain 31, the cross chain 31 is used to move in the traction track 32, in actual work, the cross chain 31 always keeps in operation, and controls whether the traction object (such as the carrying trolley 4) is connected to the cross chain 31 to control whether the traction object is traction by the cross chain 31. The traction track 32 includes an opening and an oppositely arranged "J"-shaped guide rail, the cross section of the "J"-shaped guide rail is an "J"-shaped, and the "J"-shaped guide rail is in a horizontal state, thus, the "J"-shaped guide rail includes a first vertical arm, a second vertical arm and a first horizontal arm, the first vertical arm is used as the top side of the "J"-shaped, the second vertical arm is used as the bottom side of the "J"-shaped, and the first horizontal arm is used as the vertical side of the "J"-shaped, and the three have the following relationship: the first vertical arm is parallel to the second vertical arm, the first horizontal arm is connected to the first vertical arm and the second vertical arm, and the second vertical arm extends outward. A traction channel is formed between the first horizontal arms of the same "J"-shaped guide rail, and a guide channel is formed between the second vertical arms of different "J"-shaped guide rails. The cross chain 31 includes a running wheel 311 and a chain guide wheel 312. The chain body is formed by a combination of multiple chain units and can be driven by a driving gear to run. The running wheel 311 is connected to the left and right sides of the chain body, and the running wheel 311 is located in the traction channel. The first horizontal arms on the upper and lower sides of the traction channel can be used as the support surface of the running wheel 311. When the running wheel 311 is tilted and stressed, the first horizontal arm on the top can be used to provide support, so that the cross chain 31 can still achieve stable operation. The chain guide wheel 312 is connected to the upper and lower sides of the cross chain 31, and the chain guide wheel 312 is located in the guide channel. When the running wheel 311 is tilted and stressed, the second vertical arms on the left and right sides can be used to provide support, so that the cross chain 31 can still achieve stable operation.

[0047] The present invention arranges a "J"-shaped guide rail so that the traction track 32 forms a traction channel and a guide channel. The cross-sections of the walking wheel 311, the chain guide wheel 312 and the chain body are cross-shaped. The walking wheel 311 is arranged in the traction channel, and the chain guide wheel 312 is arranged in the guide channel. Therefore, by optimizing the layout and connection method of the walking wheel 311 and the chain guide wheel 312, it is possible to ensure that under complex and changeable conveying conditions, the walking wheel 311 can maintain stable operation in the traction channel and the chain guide wheel 312 can maintain stable operation in the guide channel, effectively reduce traction resistance, and improve operation efficiency and reliability, thereby meeting the higher requirements of modern industrial production for high efficiency, intelligence and environmental protection.

[0048] In one embodiment, if Figure 4 and Figure 5As shown, the chain body includes a first chain plate group 313 and a second chain plate group 314 which are arranged at intervals and connected to each other in rotation. The first chain plate group 313 includes first chain plates arranged in parallel, and the second chain plate group 314 includes second chain plates arranged in parallel, and the first chain plate is perpendicular to the second chain plate. There is an installation space between the two first chain plates, and the installation space is provided with a connecting structure (such as a push rod 33) for connecting the towed object. A space for driving teeth to enter is formed between the two second chain plates, which is used to drive the cross chain 31 to run using the driving teeth. The first chain plate is parallel to the plane where the walking wheel 311 is located, and the first chain plate can be used to install the support shaft of the walking wheel 311. The second chain plate is parallel to the plane where the chain guide wheel 312 is located, and the second chain plate can be used to install the support shaft of the chain guide wheel 312.

[0049] In one embodiment, in combination Figure 8 , Figure 13 to Figure 15 As shown, the first chain plate group 313 and the second chain plate group 314 are connected by a cross-unit 315, and the cross-unit 315 includes an intermediate section 3151, a first shaft 3152 and a second shaft 3153, and the intermediate section 3151 has a first through hole and a second through hole for the first shaft 3152 and the second shaft 3153 to pass through, and the first through hole and the second through hole are perpendicular to each other, so that the first shaft 3152 and the second shaft 3153 are also perpendicular to each other after being installed in the intermediate section 3151. The first shaft 3152 is connected to the first chain plate group 313, and the second shaft 3153 is connected to the second chain plate group 314, so that the first chain plate group 313 can have multiple degrees of freedom relative rotation with the second chain plate group 314, so as to realize horizontal movement, turning or climbing. In addition, it should be noted that the first shaft 3152 and the second shaft 3153 are used as rotation axes, and the two can rotate relative to the intermediate section 3151, and can also rotate relative to the first chain plate group 313 and the second chain plate group 314.

[0050] In one embodiment, a push rod 33 is provided between the first chain plates, and the push rod 33 can be fixed to the first chain plates by bolts, and a push head 331 is connected to the end of the push rod 33, and the push head 331 is used to connect the lifting claw 45 of the carrying trolley 4. The cross section of the push head 331 perpendicular to its running direction is a trapezoid, and the width of the trapezoid is greater than the width of the chain body. By providing the trapezoidal push head 331, the contact area between the push head 331 and the lifting claw 45 can be increased, and the reliability of the connection can be improved.

[0051] Reference again Figure 1 to Figure 15As shown, the present invention also provides an accumulation type suspension conveyor chain system, including a load-carrying trolley 4 and a cross chain suspension conveyor device 3 as described above. The cross chain 31 is used to be connected to the load-carrying trolley 4, so that the movement of the cross chain 31 drives the movement of the load-carrying trolley 4. As needed, a load beam 6 can be connected below the load-carrying trolley 4, and a workpiece 7 is connected below the load beam 6 through a flexible chain. The load beam 6 can be installed with a lifting device with a lifting function, so that the workpiece 7 can be lifted, so as to facilitate the conveyance of the workpiece 7.

[0052] In one embodiment, if Fig. 9 and Fig.10 As shown, the load-carrying trolley 4 includes a body 41 and a lifting claw 45 connected to the body 41. The cross chain 31 is connected to a push rod 33, and the push rod 33 is connected to a push head 331. The top of the lifting claw 45 is provided with a slot for the push head 331 to be inserted into. After the push head 331 is inserted into the slot, the connection between the cross chain 31 and the load-carrying trolley 4 is realized, and the cross chain 31 can be used to drive the load-carrying trolley 4 to move. The lifting claw 45 can be raised and lowered on the body 41, and can have a tendency to be located at a high position in a natural state, so that it can be smoothly inserted into the slot and stably connected with the push head 331.

[0053] In one embodiment, if Figure 3 , Fig. 9 and Fig.10 As shown, it also includes a load-bearing track 43, which includes a U-shaped guide rail with openings arranged opposite to each other. The cross section of the U-shaped guide rail is U-shaped, and the U-shape is in a horizontal state. Therefore, the U-shaped guide rail includes a third vertical arm and a second horizontal arm. The third vertical arm serves as the top edge of the U-shaped guide rail, and the second horizontal arm serves as the two sides of the U-shaped guide rail. The relationship between the two is as follows: the second horizontal arm is connected to the third vertical arm and is distributed above and below the third vertical arm, and a load-bearing channel is formed between the second horizontal arms of the same U-shaped guide rail. The vehicle body 41 is also connected to a load-bearing wheel 42, which is located in the load-bearing channel. On the one hand, the load-bearing channel supports the load-bearing trolley 4 through the load-bearing wheel 42, and on the other hand, the load-bearing channel, the traction channel, and the guide channel together realize stable support for the operation of the load-bearing trolley 4.

[0054] In one embodiment, it also includes a trolley guide wheel 44, which is connected to the vehicle body 41, and the vehicle body 41 is located between two U-shaped guide rails. When the vehicle body 41 tends to tilt, the trolley guide wheel 44 can be used to limit the position, thereby further improving the operating stability of the load-bearing trolley 4.

[0055] In one embodiment, if Figure 1 to Figure 3As shown, it also includes a support frame 2, which is distributed on the support device 1 at intervals, and the support frame 2 is fixed by the support device 1. The traction rail 32 and the load-bearing rail 43 are both installed on the support frame 2, and the traction rail 32 is located above the load-bearing rail 43. The support frame 2 can be used to support and limit the position of the traction rail 32 and the load-bearing rail 43. The support frame 2 can adopt a frame structure, which can be composed of support rods, or the support frame 2 can adopt a block or plate structure, and the installation of the traction rail 32 and the load-bearing rail 43 is achieved by slotting.

[0056] In one embodiment, the support frame 2 adopts a plate-like structure, and the plate-like structure is provided with an installation slot, which includes a cross-shaped installation slot and an open slot connected vertically. The cross-shaped installation slot is used to install the traction rail 32, which can be fixed by welding. Since the cross-shaped installation slot has a horizontally extending groove, by inserting the left and right protrusions of the U-shaped guide rail of the traction rail 32 into the above-mentioned groove, effective support for the traction rail 32 can be formed. The open slot is used to install the load-bearing rail 43, and the load-bearing rail 43 can be connected to the open slot by welding. The slot wall of the open slot is connected to the outer bottom surface of the U-shaped guide rail, and has a sufficient connection area to ensure connection stability and effective support. It should be noted that the setting of the support frame 2 not only supports the traction rail 32 and the load-bearing rail 43 vertically, but also realizes lateral support due to the horizontal limit. In general, effective support for all directions of the traction rail 32 and the load-bearing rail 43 is realized.

[0057] In one embodiment, if Fig.11 and Fig.12As shown, the machine body also includes a stopper, which includes a frame 81, a drive cylinder 82 and a stop plate 83. The frame 81 is connected to the traction rail 32, and the traction rail 32 is used to install and fix the frame 81. One end of the drive cylinder 82 is connected to the frame 81, and the other end of the drive cylinder 82 is connected to the stop plate 83. The stop plate 83 is hinged to the frame 81. The telescopic movement of the drive cylinder 82 can drive the stop plate 83 to rotate around the hinge axis of the frame 81. For example, the stop plate 83 can adopt an L-shaped structure. When the drive cylinder 82 extends, the free end of the stop plate 83 can be driven to move upward, and when the drive cylinder 82 shortens, the free end of the stop plate 83 can be driven to move downward. The free end of the stop plate 83 is provided with a clamping head, and the travel direction of the lifting claw 45 is provided with a stop slope, and the stop slope is provided with a stop groove. When the load-carrying trolley 4 needs to be stopped, the driving cylinder 82 is retracted, and the clamping head moves downward and contacts the running stop slope. As the load-carrying trolley 4 continues to move, the lifting claw 45 is pressed down to a low position, and the clamping head is clamped into the stop groove. At this time, the lifting claw 45 is separated from the push head 331, and the load-carrying trolley 4 stops running under the obstruction of the stop plate 83. It should be noted that the stop plate 83 is located on the left and right sides of the traction track 32, and the lifting claw 45 is controlled by limiting the left and right sides of the lifting claw 45, that is, the cross chain 31 can pass through the middle of the stopper, and the stopper will not affect the operation of the cross chain 31.

[0058] In one embodiment, if Figure 5 As shown, the backstop 5 is also included. The backstop 5 is connected to the carrying rail 43. The backstop 5 is provided with a backstop slope in the oblique direction of travel, and the backstop slope is provided with a backstop tooth. In order to make the backstop 5 work, the carrying trolley 4 is equipped with a blocking structure that cooperates with the backstop tooth. The backstop 5 can be connected with a rotation drive structure, so that when the backstop function is needed, the backstop 5 can be rotated to a position that limits the backstop of the carrying trolley 4. Alternatively, the backstop 5 is only rotatably connected to the carrying rail 43, but is not connected to the rotation drive structure. By setting a limit structure, the backstop 5 can be rotated around the forward direction of the carrying trolley 4, but cannot be rotated in the reverse direction. In addition, the backstop 5 is maintained at a height that can limit the backstop of the carrying trolley 4, so that the smooth forward movement of the carrying trolley 4 is not affected.

[0059] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
