Description

Technical Field

[0001] The present invention relates to the field of drag chains, in particular to the technical field of anti-collision drag chains, and specifically refers to a high-speed silent drag chain with transversely offset rollers and a method for using the same. Background Art

[0002] Drag chains are generally used for machinery and structures with repetitive movements. They can pull and protect the cables, oil pipes, air pipes, water pipes, etc. placed within them. They can be divided into many different types according to their classification methods. According to the material, they can be divided into steel drag chains, steel-aluminum drag chains, plastic drag chains, stainless steel drag chains, and nylon drag chains; according to the form, they can be divided into bridge drag chains, closed drag chains, silent drag chains, open drag chains, and threading drag chains; according to the assembly form, they can be divided into bridge drag chains, fully enclosed drag chains, and semi-enclosed drag chains. Different types of drag chains are suitable for different scenarios. Therefore, drag chains are widely used in various industries such as CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machines, robots, overweight transportation equipment, and automated warehouses.

[0003] The drag chain includes a main body, but in actual use, since the main body is gradually flipped from the lower layer to the upper layer, if the main body is long, the upper layer of the main body will droop, causing the upper and lower layers of the drag chain to collide with each other and wear.

[0004] At present, in order to solve the problem of the upper drag chain sagging, rollers are usually installed on the upper surface of the main body. By setting the rollers, direct contact between the upper and lower layers of the drag chain main body is prevented. However, after the lower layer main body is flipped to the upper layer, the positions of the rollers of the upper and lower layers will overlap, resulting in the problem of ups and downs and vibration of the drag chain. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a high-speed silent drag chain with horizontally offset rollers and a method for using the same, so that when the rollers are flipped upwards, they automatically move toward the main body, thereby achieving the offset of the upper and lower rollers and avoiding the occurrence of fluctuations and vibrations in the drag chain.

[0006] The present invention is achieved through the following technical solution: a high-speed silent drag chain with horizontally offset rollers and a method of using the same, comprising a main body provided with rollers, and support blocks fixedly connected to both sides of the main body, the support blocks being provided with the rollers, and the support blocks being further provided with a first drive device for driving the rollers to move axially along the rollers.

[0007] The present invention sets a first driving device. When the main body is located at the bottom, the first driving device drives the roller away from the main body; when the main body is flipped to the top, the first driving device drives the roller close to the main body, thereby achieving misalignment of the upper and lower rollers and avoiding the occurrence of ups and downs and vibrations of the drag chain.

[0008] Preferably, the first driving device comprises a slide plate sliding in the support block along the axis of the roller, one end of the slide plate is axially connected to the roller, the other end of the slide plate is a first inclined surface inclined toward the side of the slide plate, and the side of the slide plate away from the inclined surface is connected to the support block via a first spring;

[0009] A push plate is also provided in the support block, which moves in the height direction and extends out of the support block. One end of the push plate is located in the support block and is pressed against the first inclined surface. The first spring and the push plate are located on both sides of the slide. A second driving device is also provided in the support block to drive the push plate to move.

[0010] When the preferred solution is in use, when the main body is located at the bottom, the second driving device is driven to drive the push plate to move into the support block. Under the action of the support block and the first inclined surface, the push plate moves into the support block to push the slide plate to move along the roller axis toward the main body. The movement of the push plate drives the roller to move toward the main body, while compressing the first spring.

[0011] When the main body is at the top, the second driving device is driven to drive the push plate to extend outward from the support block, so that the push plate is away from the first inclined surface. At this time, under the elastic force of the first spring, the slide plate is pushed to move along the axial direction of the roller away from the main body. The movement of the push plate drives the slide plate to move along the axial direction of the roller away from the main body. The roller located above is away from the main body, and the roller located below is close to the main body, so that the two rollers are misaligned.

[0012] Preferably, the second driving device includes a second spring that is retracted and contracted in the height direction, and a connecting plate is provided between the end of the second spring away from the roller and the support plate, and the connecting plate is fixedly connected to the push plate.

[0013] When the preferred solution is in use, when the main body is at the bottom, the push plate extends downward under the action of the elastic force of the second spring. Under the action of the gravity of the drag chain, the end of the push plate extending from the support block presses against the bottom plate, and the bottom plate drives the push plate to move into the support block, compressing the second spring, thereby realizing the push plate moving into the support block;

[0014] When the main body is turned over from the bottom to the top, the push plate is away from the bottom plate, and the restraint of the bottom plate on the push plate is released. Under the elastic force of the second spring, the push plate is pushed to extend out of the support block.

[0015] Preferably, the end surface of the push plate that contacts the first inclined surface is a second inclined surface that matches the first inclined surface. This preferred solution allows the push plate to contact two surfaces of the slide plate by providing the first inclined surface and the second inclined surface, thereby avoiding line-surface contact that could damage the push plate and slide plate, and extending the service life of the push plate and slide plate.

[0016] Preferably, the push plate is axially connected to a rotating wheel having a second inclined surface extending from a circumferential surface and in contact with the first inclined surface. This preferred solution converts sliding friction into rolling friction through the arrangement of the rotating wheel, thereby reducing the friction between the push plate and the slide plate, and ensuring that the push plate pushes the slide plate smoothly.

[0017] Preferably, the first spring is sleeved on a guide post extending along the axial direction of the roller, and the guide post is slidably connected to the slide plate. This preferred solution supports the spring through the provision of the guide post, and provides the spring with a guiding effect when the spring is extended and retracted.

[0018] Preferably, the support block is provided with a through hole for the push plate to extend out of the support block, and the size of the through hole is adapted to the size of the push plate. This preferred solution provides a guiding effect when the push plate moves through the arrangement of the through hole.

[0019] The method of using the roller horizontally offset high-speed silent drag chain includes the following steps:

[0020] a. When the main body is at the bottom, under the action of the elastic force of the second spring, the push plate extends downward. Under the action of the gravity of the drag chain, one end of the push plate extending from the support block presses against the bottom plate, and the bottom plate drives the push plate to move into the support block. The push plate moves into the support block, driving the connecting plate to move upward, thereby compressing the second spring. At the same time, the push plate moves upward, driving the rotating wheel to move upward. Under the cooperation of the rotating wheel and the first inclined surface, the rotating wheel moves upward and drives the slide plate to move along the axial direction of the roller toward the main body. The movement of the slide plate drives the roller to move toward the main body while compressing the first spring.

[0021] b. When the main body flips from the bottom to the top, the bottom plate releases the restraint of the push plate. Under the elastic force of the second spring, the push plate is pushed to extend outward from the support block, thereby moving the rotating wheel away from the first inclined surface. At this time, under the elastic force of the first spring, the slide plate is pushed to move along the axial direction of the roller away from the main body. The movement of the push plate drives the slide plate to move along the axial direction of the roller away from the main body. The roller located above is away from the main body, and the roller located below is close to the main body, thereby causing the two rollers to be misaligned.

[0022] The beneficial effects of the present invention are as follows: through the setting of the first driving device, when the main body is located at the bottom, the roller is driven away from the main body, and when the main body is flipped to the top, the roller is driven close to the main body, thereby realizing the misalignment of the upper and lower rollers, avoiding the upper and lower rollers colliding with each other, causing the drag chain to vibrate, and at the same time no collision occurs between the rollers, and the sound of the roller collision is eliminated, achieving a silent effect; through the setting of the rotating wheel, the sliding friction is converted into rolling friction, the friction between the push plate and the skateboard is reduced, and the push plate is guaranteed to push the skateboard smoothly; through the setting of the guide column, the spring is supported while giving the spring a guiding effect when the spring is extended and contracted; through the setting of the perforation, a guiding effect is given when the push plate moves.

[0030] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0031] Refer to the attached Figure 1-5 The present invention provides a high-speed silent drag chain with horizontally offset rollers 4 and a method for using the same, comprising a main body 1 provided with rollers 4, and support blocks 2 fixedly connected to both sides of the main body 1, wherein the support blocks 2 are provided with the rollers 4, and the support blocks 2 are also provided with a first driving device for driving the rollers 4 to move axially along the rollers 4.

[0032] The first driving device includes a slide plate 5 that slides axially along the roller 4 in the support block 2. One end of the slide plate 5 is axially connected to the roller 4. The other end of the slide plate 5 is a first inclined surface that is inclined toward the side of the slide plate 5. The side of the slide plate 5 away from the inclined surface is connected to the support block 2 via a first spring 9.

[0033] A push plate 3 is also provided in the support block 2, which moves in the height direction and extends out of the support block 2. One end of the push plate 3 is located in the support block 2 and is pressed against the first inclined surface. The first spring 9 and the push plate 3 are located on both sides of the slide plate 5. A second driving device is also provided in the support block 2 to drive the push plate 3 to move.

[0034] The second driving device includes a second spring 10 that is retracted in the height direction. A connecting plate 8 is provided between the end of the second spring 10 away from the roller 4 and the support plate. The connecting plate 8 is fixedly connected to the push plate 3.

[0035] The end surface of the push plate 3 that contacts the first inclined surface is a second inclined surface that matches the first inclined surface.

[0036] A rotating wheel 7 is axially connected to the push plate 3 and has a second inclined surface extending from its circumferential surface and in contact with the first inclined surface.

[0037] The first spring 9 is sleeved on a guide post 6 extending axially along the roller 4 , and the guide post 6 is slidably connected to the slide plate 5 .

[0038] The support block 2 is provided with a through hole for the push plate 3 to extend out of the support block 2 , and the size of the through hole is adapted to the size of the push plate 3 .

[0039] The method of using the roller 4 transversely displaced high-speed silent drag chain includes the following steps:

[0040] a. When the main body 1 is at the bottom, under the action of the elastic force of the second spring 10, the push plate 3 extends downward. Under the action of the gravity of the drag chain, one end of the push plate 3 extending from the support block 2 presses against the bottom plate, and the bottom plate drives the push plate 3 to move into the support block 2. The push plate 3 moves into the support block 2, driving the connecting plate 8 to move upward, thereby compressing the second spring 10. At the same time, the push plate 3 moves upward, driving the runner 7 to move upward. Under the cooperation of the runner 7 and the first inclined surface, the runner 7 moves upward, driving the slide plate 5 to move along the axial direction of the roller 4 toward the main body 1. The movement of the slide plate 5 drives the roller 4 to move toward the main body 1 while compressing the first spring 9.

[0041] b. When the main body 1 flips from the bottom to the top, the restraint of the bottom plate on the push plate 3 is released. Under the elastic force of the second spring 10, the push plate 3 is pushed to extend outward from the support block 2, thereby moving the rotating wheel 7 away from the first inclined surface. At this time, under the elastic force of the first spring 9, the slide plate 5 is pushed to move along the axial direction of the roller 4 away from the main body 1. The movement of the push plate 3 drives the slide plate 5 to move along the axial direction of the roller 4 away from the main body 1. The roller 4 located above is away from the main body 1, and the roller 4 located below is close to the main body 1, thereby causing the two rollers 4 to be misaligned.
