Description

Technical Field

[0002] Currently, in industrial production, simple V-shaped or arc-shaped supports are generally used for the transfer and transportation of tubular or cylindrical products, supplemented by fixing methods such as pressure blocks, steel belts or ropes to fix the tubular or cylindrical products on the V-shaped or arc-shaped supports to prevent them from falling and ensure the safety of transfer and transportation.

Other modifications within the scope and spirit of the present disclosure will occur to those skilled in the art.

[0037] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present disclosure and, together with the general description of the present disclosure given above and the detailed description of the embodiments given below, serve to explain the principles of the present disclosure.

[0038] These and other characteristics of the present disclosure will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0039] It should also be understood that although the present disclosure has been described with reference to certain specific examples, those skilled in the art will be able to realize many other equivalent forms of the present disclosure that have the characteristics recited in the claims and are therefore within the scope of protection defined thereby.

[0040] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0041] Specific embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant detail. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but rather serve merely as a basis and representative basis for teaching those skilled in the art to variously employ the present disclosure with substantially any suitable detailed structure.

[0042] This description may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0043] The first embodiment of the present disclosure proposes a transport carrier, which is used to fix a clamped object and can also achieve fixation and locking based on the weight of the clamped object. The clamped object here is particularly a tubular or columnar structure, and can particularly be a round tube.

[0044] Specifically, Figure 1 and Figure 2 A transfer carrier 100 is shown, which includes a carrier base 101 and a plurality of support devices 200 arranged on the carrier base 101, wherein the plurality of support devices 200 are arranged at intervals along the length direction of the carrier base 101, wherein the central axes of the plurality of support devices 200 coincide, and the plurality of support devices 200 are used to fix and lock the clamping object 300.

[0045] Furthermore, the carrier base 101 is provided with a plurality of slides 102, which are movable along the length of the carrier base 101. Specifically, a slide groove is provided on the upper surface of the carrier base 101, and the slide groove is provided along the length of the carrier base 101. The slides 102 slide on the slide groove 2. In this embodiment, the slides 102 can extend along the width direction of the carrier base 101 and can slide along the length of the carrier base 101.

[0046] Furthermore, the slide plate 102 can be positioned after sliding to a predetermined position. For example, the slide plate 102 can be detachably fixed to the carrier base 101 by screws. Figure 1 and Figure 2 As shown, the upper surface of the carrier base 101 is provided with a mounting hole 103 , and screws screwed into the mounting hole 103 can realize a detachable connection between the slide plate 102 and the carrier base 101 , thereby realizing the positioning of the slide plate 102 .

[0047] Furthermore, the supporting device 200 is arranged on each of the slides 102, and the clamping object 300 is fixed by multiple supporting devices 200. In this way, by sliding the slide 102, the distance between two adjacent supporting devices 200 can be flexibly adjusted according to actual clamping requirements, thereby meeting the fixing requirements of the clamping objects 300 of various different lengths.

[0048] Furthermore, a plurality of guide wheels 104 are provided on the side of the carrier base 101. The guide wheels 104 are provided to protect the carrier base 101 so that the carrier base 101 can roll in contact with other objects, thereby preventing the carrier base 101 from coming into contact with other objects during transportation and transfer and causing severe friction and damage.

[0049] Furthermore, a lifting ring 105 is provided on the upper surface of the carrier base 101 . The lifting ring 105 facilitates the lifting of the carrier base 101 . The lifting ring 105 is particularly provided at the end of the carrier base 101 .

[0050] In the embodiment of the present disclosure, the clamp is placed on the support device on the carrier base to achieve fixation and locking, and there is no need to manually lock the screws of the clamp. It can be applied to the support of clamps of various specifications, improve the stability of the clamp transportation, ensure the positioning accuracy of the clamp on the support device, and at the same time reduce the risk of product damage and reduce damage costs.

[0051] A second embodiment of the present disclosure provides a supporting device for supporting a clamping object such as a round tube, so as to fix and lock the clamping object after the clamping object is placed. Figure 3-Figure 12 A supporting device 200 is shown, which includes a supporting frame 1. The supporting frame 1 is a hollow shell structure, and a self-locking device is movably arranged inside the supporting frame. The self-locking device can move up and down relative to the supporting frame 1, so that the clamping object can be fixed and locked after the clamping object is placed.

[0052] Specifically, the support frame 1 includes a base portion 11 and a support portion 12. The bottom of the base portion 11 is an open structure. The support portion 12 is used to support the self-locking device and can accommodate the clamping object 300. The support portion 12 has an arc-shaped end surface. The clamping object 300 can be supported inside the arc-shaped end surface of the support portion 12 and supported by the self-locking device. The self-locking device here can fix and lock the clamping object 300.

[0053] Specifically, the self-locking device can extend out of the arc-shaped end surface or retract into the arc-shaped end surface by moving, wherein, when the clamp 300 is not placed on the self-locking device, the self-locking device can extend upward from the arc-shaped end surface and be in an unlocked state. When the clamp 300 is placed on the self-locking device, based on the self-gravity of the clamp 300, the self-locking device is retracted into the arc-shaped end surface and the clamp 300 is tightly clamped and is in a locked state.

[0054] like Figure 2 、 Figure 3 as well as Figure 4 As shown, the self-locking device includes a lifting support assembly 2, and the lifting support assembly 2 includes a support column 2a extending along a first direction, and the end of the support column 2a is provided with a support seat 2b extending along a second direction, wherein the end of the support column 2a is connected to the middle of the support seat 2b, and a support plate 24 for supporting the clamping object 300 is provided on the support seat 2b, and the support plate 24 here is made of polyurethane.

[0055] Furthermore, the two ends of the support seat 2b are respectively movably connected to the adjustable support rod assembly 5, and the adjustable support rod assembly 5 can be rotated relative to the support seat 2b to achieve unlocking or locking. A clamping assembly is provided at the end of the adjustable support rod assembly 5, so that when the clamping object 300 is placed on the self-locking device, the clamping assembly can clamp the clamping object 300.

[0056] In this embodiment, the adjustable support rod assembly 5 is used to clamp and fix the tubular or cylindrical clamp 300 through the clamping assembly. When the clamp 300 is placed, the clamp 300 presses the support plate 24 based on its weight, and presses down the support seat 2b connected to the adjustable support rod assembly 5, thereby driving the inward rotation of the adjustable support rod assembly 5, so that the clamping assembly at the end of the adjustable support rod assembly 5 presses the clamp 300 inward, thereby fixing and clamping the clamp 300. When the clamp 300 moves up and separates from the support plate 24, the outward rotation of the adjustable support rod assembly 5 separates the clamping assembly at the end of the adjustable support rod assembly 5 from the clamp 300.

[0057] Furthermore, a first support block 28 is provided in the middle of the adjustable support rod assembly 5 , which fixes and locks the clamping object 300 through the cooperation between the support plate 24 and the clamping assembly.

[0058] Furthermore, notches 121 are symmetrically provided on the outer sides of the two distal ends of the support portion 12 , and the notches 121 enable the adjustable support rod assembly 5 to be tilted to both sides to be unlocked and opened without placing the clamp 300 .

[0059] Specifically, second support blocks 241 are respectively arranged at both ends of the support plate 24, and the second support blocks 241 have a first inclined surface 2411, a vertical surface 2412 and a second inclined surface 2413, wherein the first inclined surfaces 2411 of the two second support blocks 241 are arranged opposite to each other and are used to contact the outer surface of the clamp 300, and the connection between the vertical surface 2412 and the second inclined surface 2413 is used to squeeze the self-locking device downward after the clamp 300 is placed, so that the self-locking device can lock the clamp 300.

[0060] To facilitate the rotation of the adjustable support rod assembly 5 relative to the jacking support assembly 2 and the support frame 1, the middle portion of the adjustable support rod assembly 5 is rotatably connected to the support portion 12 of the support frame 1 via a first axle pin 3, and the first end of the adjustable support rod assembly 5 is connected to the support base 2b via a second axle pin 21. Preferably, a waist-shaped hole is provided on the adjustable support rod assembly 5 to respectively cooperate with the first axle pin 3 and the second axle pin 21, thereby facilitating the restriction of the adjustable support rod assembly 5 within a certain range of motion.

[0061] like Figure 3 and Figure 4 As shown, in one embodiment, the bottom of the base portion 11 is an open structure, the support column 2a is a screw, the support seat 2b here can move relative to the support column 2a, and the bottom of the support column 2a abuts against the slide 102.

[0062] Furthermore, a nut 26 is sleeved on the support column 2a, and a first spring 27 is sleeved on the support column 2a between the nut 26 and the support seat 2b. The upper end of the first spring 27 is in conflict with the lower surface of the support plate 24, and the lower end of the first spring 27 is in conflict with the nut 26. When it is necessary to reduce the clamping force of the adjustable support rod assembly 5 on the clamping object 300, the nut 26 is screwed and the spiral is raised to further squeeze the first spring 27, thereby increasing the lifting force of the first spring 27 on the support plate 24, thereby reducing the downward pressure on the support plate 24, and The downward pressure applied to the adjustable support rod assembly 5 decreases, and the clamping force of the clamped object 300 by the adjustable support rod assembly 5 decreases accordingly. Conversely, the clamping force of the adjustable support rod assembly 5 on the clamped object 300 can be increased by screwing the nut 26 downward. Here, the clamping force of the adjustable support rod assembly 5 on the clamped object 300 can be adjusted. On the one hand, it can avoid that the clamping force is too large and the product is damaged, especially some hollow tubular or cylindrical products, which are not easy to be clamped too tightly, otherwise the outer wall of the product will be deformed. On the other hand, in some cases, the clamped tubular or cylindrical products need to be rotated, and in this case, it is avoided that clamping too tightly will make the product difficult to rotate.

[0063] The working principle of the above structure is as follows: when the clamping object 300 is not placed on the supporting device 200 of this embodiment, the supporting device 200 of this embodiment is in a normally open or unlocked state, such as Figure 4 As shown; when the clamp 300 is placed on the support device 200, the clamp 300 presses down the support plate 24 to drive the adjustable support rod assembly 5 to rotate around the second pin 21, and the clamping assembly is used to cooperate with the support plate 24 to clamp the clamp 300 with the help of the adjustable support rod assembly 5 through the gravity of the clamp 300 itself.

[0064] When the clamp 300 is lifted, the pressure on the support plate 24 is reduced, and the adjustable support rod assembly 5 rotates and opens again under the action of its own weight, making it convenient to separate the clamp 300 from the support plate 24, thereby achieving automatic opening and closing with the help of gravity, without the need to use external objects to fix the clamp 300. Therefore, the clamp 300 can be removed or placed on the support device 300 by a robot, realizing fully automatic fastening or disassembly of tubular or columnar products without manual assistance, saving time and effort, and greatly improving the fastening and disassembly efficiency of tubular or columnar products, thereby improving the transportation and delivery efficiency of tubular or columnar products and the production efficiency of the enterprise.

[0065] In another embodiment, Figure 5-Figure 12As shown, the base portion 11 may have a bottom plate, which is used to contact and cooperate with the self-locking device, especially with the bottom of the support column 2a. The bottom of the support column 2a is provided with a second spring 22, and the second spring 22 on the support column 2a can cooperate with the bottom plate of the base portion 211.

[0066] Furthermore, a fixing ring 25 is provided on the support column 2a, and a mounting hole is provided on the fixing ring 25. A ball screw 23 is provided in the mounting hole. Here, the ball screw 23 cooperates with the support frame 1 to limit the position of the self-locking device. Preferably, the contact portion between the mounting hole and the ball screw 23 is configured as a semicircular arc cutout, which can ensure that the ball head surface of the ball screw 23 stably contacts the mounting hole.

[0067] Furthermore, a limiting hole 213 is provided on the support frame 1. When the support column 2a is moved to allow the ball head screw 23 to extend into the limiting hole 213, the self-locking device is limited in the support frame 1 and cannot move up and down. When the ball head screw 23 is pressed, the limitation on the self-locking device is released so that the self-locking device can move up and down relative to the support frame 1.

[0068] When the clamp 300 is not placed on the lifting support assembly 2, the second spring 22 is in an uncompressed state, and the support plate 24 of the self-locking device extends outward from the arc end surface and enables the two adjustable support rod assemblies 5 to open outward through the notch 2121 and be in an unlocked state; when the clamp 300 is placed on the lifting support assembly 2, the second spring 22 is compressed by the dead weight of the clamp 300, so that compression is achieved between the second spring 22 and the bottom plate, so that the self-locking device extends into the arc end surface and is located in the support frame 1, and at the same time, the second support block 241 on the support plate 24 squeezes the adjustable support rod assembly 5 downward, and the two adjustable support rod assemblies 5 rotate inwardly under the action of the squeezing force to be recovered and hold the clamp 300 tightly through the clamping assembly, thereby achieving support and self-locking of the clamp 300, so that the clamp 300 can be restricted on the support frame 1.

[0069] Furthermore, the two distal ends of the support portion 12 are symmetrically provided with a third support block 4, and the third support block 4 includes a main body 41, and the main body 41 is located on the inner side surface of the distal end portion of the support portion 12 and is respectively connected to the two end faces of the distal end portion of the support portion 12 through two connecting arms 42. The side surface of the main body 41 of the third support block 4 can support the clamping object 300, and the self-locking device can pass through between the two connecting arms 42, and the self-locking device can be limited by the two connecting arms 42.

[0070] Furthermore, the adjustable support rod assembly 5 includes a first rod body 51 and a second rod body 52, wherein a certain angle is formed between the first rod body 51 and the second rod body 52, and the second rod body 52 here is preferably arc-shaped. The arc-shaped second rod body 52 is used here to facilitate matching the surface of the clamping object 300. In addition, a weight-reducing groove 521 is provided on the second rod body 52.

[0071] To facilitate the rotation of the adjustable support rod assembly 5 relative to the jacking support assembly 2 and the support frame 1, the first end of the first rod body 51 is connected to the support base 2b via a second axle pin 21, and the second end of the first rod body 51 is connected to the support portion 12 via a first axle pin 3. Preferably, a waist-shaped hole is provided on the adjustable support rod assembly 5 to respectively cooperate with the first axle pin 3 and the second axle pin 21, thereby facilitating the restriction of the adjustable support rod assembly 5 within a certain range of motion.

[0072] The clamping assembly described in any of the above items is arranged at the adjustable support rod assembly 5, especially at the end of the second rod body 52, and the clamping assembly includes a first fixed block 7, and the first fixed block 7 is connected to the end of the second rod body 52 through a third axis pin 8, and an adjustable knob 9 is provided on the third axis pin 8. By operating the adjustable knob 9, the position of the first fixed block 7 can be adjusted through the third axis pin 8, thereby realizing the adjustment of the clamping position.

[0073] Preferably, a second fixing block 6 is provided between the first fixing block 7 and the adjustable knob 9. The hardness of the second fixing block 6 is greater than that of the first fixing block 7. The first fixing block 7 is made of polyurethane, for example. By adjusting the adjustable knob 9, the pressure of the first fixing block 7 on the clamp 300 can be adjusted, thereby ensuring the support and holding strength of the clamp 300. Preferably, the adjustable knob 9 requires manual operation and has a knurled surface.

[0074] In this embodiment, all portions of the support device that come into contact with the clamp 300 are made of polyurethane to prevent scratching of the tube surface. These contact surfaces include, for example, the aforementioned second support block 241, the third support block 4, the first support block 28, and the support surfaces of the first fixing block 7. Furthermore, the edges of the second support block 241, the third support block 4, the first support block 28, and the first fixing block 7 are rounded to further reduce the risk of scratching the tube surface.

[0075] The working principle of the support device using the embodiment of the present disclosure is as follows: first, the clamp 300 is placed on the support plate 24 of the jacking support assembly 2. When the outer surface of the clamp 300 contacts the second support block 241 of the support plate 24, the clamp 300 presses the jacking support assembly 2 downward under the action of gravity, so that the second spring 22 is compressed with the bottom plate of the base portion 2. At the same time, the second support block 241 squeezes the adjustable support rod assembly 5, thereby driving the two adjustable support rod assemblies 5 to rotate inward at the same time and tighten, so that the first fixing block 7 of the clamping assembly contacts the outer surface of the clamp 300 and holds the clamp 300 tightly, thereby realizing the automatic locking function. In this way, on the basis of setting the jacking support assembly, the two adjustable support rod assemblies can move in place synchronously to ensure that the clamp is stably supported on the self-locking device.

[0076] When the clamp 300 needs to be removed from the support device, the clamp 300 is lifted up so that the first fixing block 7 is out of contact with the clamp 300 and is subjected to outward force, driving the adjustable support rod assembly 5 to open to both sides, and the second spring 22 is released from compression to drive the lifting support assembly 2 to move upward, thereby achieving automatic unlocking of the clamp 300.

[0077] In the embodiment of the present disclosure, automatic locking is achieved by placing the clamp on the self-locking device, and automatic unlocking is achieved by removing the clamp from the self-locking device. There is no need for manual screw locking, and the system is applicable to the self-locking support and unlocking of clamps of various specifications, thereby improving the stability of the clamp transportation, ensuring the positioning accuracy of the clamp on the support device, and reducing the risk of product damage and the cost of damage.
