Description

Technical Field

[0001] The utility model relates to the technical field of pipe material processing, and more specifically, it relates to a pipe material unbundling device. Background Art

[0002] In order to facilitate the transportation and placement of pipe materials, the pipe materials are usually tied into a hexagonal cross-section shape or other shapes by straps or other ropes. This makes it necessary to cut the straps or ropes when processing the pipe materials. Since the straps are tied very tightly to the pipe materials, when manually cutting the straps, the elastic force on the straps will cause the straps to rebound, which is likely to cause harm to the workers. Therefore, an unbundling device is needed to protect the safety of the workers. Content of the Utility Model

[0003] The utility model overcomes the deficiency that when the bundled materials are directly removed manually in the prior art, the straps on the bundled materials rebound, which is likely to cause harm to the workers, and provides a pipe material unbundling device, which can clamp the bundled materials, so that the straps on the bundled materials lose their resilience. When the straps are cut, the straps will not rebound, thus avoiding harm to the workers caused by the rebound of the straps.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a pipe material unbundling device, comprising: a placement rack for placing the bundled materials, a plurality of fixed clamping rods are arranged on one side in the width direction of the placement rack, a plurality of movable clamping rods are arranged on the other side in the width direction of the placement rack, and a plurality of driving devices drive the movable clamping rods to reciprocate towards the fixed clamping rods.

[0005] In the utility model, the placement rack is used to place the bundled materials. After the bundled pipe materials are placed on the placement rack, the driving device drives the movable clamping rods to move, so that the movable clamping rods move towards the fixed clamping rods, and the bundled materials are clamped by the fixed clamping rods and the movable clamping rods. The clamped bundled materials will shrink, so that the elastic force on the straps disappears. When the worker cuts the straps, the straps will not bounce at this time because there is no elastic force, thus preventing the rebounding straps from harming the operating workers.

[0006] Preferably, one end of the movable clamping rod is connected to the driving device, and a bent rod is arranged at the other end of the movable clamping rod; a rotating hole is arranged between the connection point of the movable clamping rod and the driving device and the bent rod, and a rotating shaft is arranged on the placement rack, and the rotating hole rotates around the rotating shaft.

[0007] The arrangement of the bent rod enables it to better cooperate with the fixed clamping rod, so that the bundled materials can be clamped more stably.

[0008] Preferably, the straight-line distance from the rotation hole to the end of the bending rod is L1, and the straight-line distance from the rotation hole to the connection between the driving device and the movable clamping rod is L2, where L1 is greater than L2.

[0009] Since one end of the bending rod needs to clamp the bundled material, the force arm at one end of the bending rod is set longer, enabling the pipe material to be clamped more stably and allowing the hydraulic rod to move a small stroke to make the movable clamping rod rotate a larger angle.

[0010] Preferably, each movable clamping rod is correspondingly connected to a driving device.

[0011] Each hydraulic cylinder provides a clamping force for a movable clamping rod alone, thus providing a more stable clamping force for the bundled material and enabling the bundled material to be clamped tighter.

[0012] Preferably, the number of driving devices is less than the number of movable clamping plates, and the ends of several movable clamping rods away from the bending rod are connected by a connecting rod.

[0013] This enables all the movable clamping rods to be driven by two driving devices or even one driving device.

[0014] Preferably, the placement rack includes several parallel load-bearing rods, the fixed clamping rod is fixedly arranged at one end of the load-bearing rod, and the movable clamping rod is in a non-working state at the lower end of the load-bearing rod.

[0015] The movable clamping rod is located below the upper surface of the load-bearing rod, not affecting the placement of the bundled material.

[0016] Preferably, the load-bearing rods are inclined away from the fixed clamping rod.

[0017] The cylindrical pipe material can automatically roll down along the load-bearing rod. After rolling down from the load-bearing rod, the pipe material can undergo the next step of processing, enabling the pipe material in the area of the load-bearing rod between the fixed clamping rod and the movable clamping rod to be automatically emptied from this area.

[0018] Preferably, the driving device is a hydraulic cylinder, and the movable end of the hydraulic cylinder is rotationally connected to the movable clamping rod.

[0019] Using a hydraulic cylinder as the driving device can provide sufficient driving force to drive the movable clamping rod to rotate.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] The placement rack in this utility model is used to place bundled materials. After the bundled pipe materials are placed on the placement rack, the driving device drives the movable clamping rod to move, so that the movable clamping rod moves towards the direction close to the fixed clamping rod, and the bundled materials are clamped by the fixed clamping rod and the movable clamping rod. The clamped bundled materials will shrink, so that the elastic force on the binding belt disappears. When the worker cuts the binding belt, the binding belt at this time will not bounce because there is no elastic force, thus preventing the rebounding binding belt from hurting the operating worker.

[0028] The following will further specifically describe the technical solutions of this utility model through specific embodiments in conjunction with the drawings:

[0029] Embodiment 1: Refer to Figures 1 to 4 As shown, a device for unbundling pipe materials includes a placement rack for placing bundled materials. On one side in the width direction of the placement rack, there are several fixed clamping rods 2, and on the other side in the width direction of the placement rack, there are several movable clamping rods 3. Several driving devices 4 drive the movable clamping rods 3 to reciprocate towards the direction of the fixed clamping rods 2.

[0030] The placement rack is used to place bundled materials. After the bundled pipe materials are placed on the placement rack, the driving device 4 drives the movable clamping rod 3 to move, so that the movable clamping rod 3 moves towards the direction close to the fixed clamping rod 2, and the bundled materials are clamped by the fixed clamping rod 2 and the movable clamping rod 3. The clamped bundled materials will shrink, so that the elastic force on the binding belt disappears. When the worker cuts the binding belt, the binding belt at this time will not bounce because there is no elastic force, thus preventing the rebounding binding belt from hurting the operating worker.

[0031] Embodiment 2: Refer to Figures 1 to 4As shown in the figure, a tube material unbundling device includes a placement rack for placing bundled materials. The placement rack includes a number of load-bearing racks 11 arranged in parallel. The adjacent load-bearing racks 11 are connected by connecting rod members 12 to form the entire placement rack structure. Two parallel load-bearing rods 13 are provided on each load-bearing rack 11. When the bundled materials are placed on the load-bearing rods 13, the tube materials are perpendicular to the load-bearing rods 13.

[0032] On one side in the width direction of the placement rack, a number of fixed clamping rods 2 are provided. On the other side in the width direction of the placement rack, a number of movable clamping rods 3 are provided. A number of driving devices 4 drive the movable clamping rods 3 to reciprocate towards the fixed clamping rods 2.

[0033] In this embodiment, the fixed clamping rods 2 are fixedly arranged at one end of the load-bearing rods 13, and the movable clamping rods 3 are in a non-working state at the lower end of the load-bearing rods 13. The number of fixed clamping rods 2 is the same as the number of load-bearing racks 11, and the number of movable clamping rods 3 is the same as the number of fixed clamping rods 2. Moreover, each movable clamping rod 3 and its corresponding fixed clamping rod 2 are arranged in the same lateral direction of the placement rack.

[0034] The movable clamping rods 3 and the driving devices 4 are installed between the two load-bearing rods 13. One end of the movable clamping rod 3 is connected to the driving device 4. The driving device 4 uses a hydraulic cylinder, which can provide sufficient driving force to drive the movable clamping rod 3 to rotate. The driving device 4 includes but is not limited to a hydraulic cylinder. The other end of the movable clamping rod 3 is provided with a bending rod 31; a rotating hole 32 is provided between the connection point of the movable clamping rod 3 and the driving device 4 and the bending rod 31. A rotating shaft 14 is fixedly arranged on the placement rack. The rotating shaft 14 is arranged below the load-bearing rods 13, and the rotating hole 32 rotates around the rotating shaft 14.

[0035] In the non-working state, the movable clamping rod 3 is located at a position below the upper end surface of the load-bearing rod 13, which does not affect the placement of the bundled materials. When it is necessary to unbind the bundled materials, the hydraulic cylinder drives its movable end to drive the movable clamping rod 3 to move, so that the movable clamping rod 3 rotates around the rotating shaft 14, thereby enabling the bending rod 31 to rotate towards the direction close to the fixed clamping rod 2. The setting of the bending rod 31 enables it to cooperate better with the fixed clamping rod 2, making it more stable when clamping the bundled materials, thereby compressing the tube materials, causing the straps tied to the bundled materials to contract, and the elastic force on the straps to disappear. After the straps are cut, the straps will not rebound. Then, the movable clamping rod 3 is reset under the action of the hydraulic cylinder, and the movable clamping rod 3 returns below the load-bearing rod 13, allowing the tube materials to be placed on the load-bearing rack 11 and waiting for further processing.

[0036] The load-bearing rod 13 is inclined away from the fixed clamping rod 2. That is to say, the height of the load-bearing rod 13 at the movable clamping rod 3 is lower than the height of the load-bearing rod 13 at the fixed clamping rod 2. Thereby enabling the cylindrical pipe material to automatically roll downward along the load-bearing rod 13. After rolling down from the load-bearing rod 13, the pipe material can be processed in the next step, so that the pipe material on the area of the load-bearing rod 13 between the fixed clamping rod 2 and the movable clamping rod 3 is automatically emptied from this area.

[0037] The straight-line distance from the rotation hole 32 to the end of the bending rod 31 is L1, and the straight-line distance from the rotation hole 32 to the connection between the driving device 4 and the movable clamping rod 3 is L2, and L1 is greater than L2. Since one end of the bending rod 31 needs to clamp the bundled material, the lever arm of one end of the bending rod 31 is set longer, so that the pipe material can be clamped more stably, and it also enables the hydraulic rod to move a very small stroke to make the movable clamping rod 3 rotate a larger angle.

[0038] In this embodiment, the number of the driving devices 4 and the movable clamping rods 3 is the same, that is to say, each movable clamping rod 3 is connected to a separate hydraulic cylinder. Each hydraulic cylinder provides a clamping force for a movable clamping rod 3 separately.

[0039] The working principle of this embodiment is as follows: First, place the bundled material on the placement rack. At this time, the pipe material is perpendicular to the load-bearing rack 11. Then the hydraulic cylinder is started, and the movable end of the hydraulic cylinder drives the movable clamping rod 3 to rotate, so that the movable clamping rod 3 rotates. When the movable clamping rod 3 rotates, the bending rod 31 moves towards the direction close to the fixed clamping rod 2. Then the fixed clamping rod 2 and the movable clamping rod 3 cooperate to clamp the bundled material. After the bundled material is clamped, the elastic force on the binding belt of the bundled material weakens or disappears. Then the worker cuts the binding belt. At this time, the binding belt will not rebound. The pipe material in the bundled material spreads out between the fixed clamping plate and the movable clamping plate. Then the hydraulic cylinder drives the movable clamping rod 3 to reset, and the movable clamping rod 3 resets below the load-bearing rod 13 again, and the pipe material is placed on the load-bearing rod 13.

[0040] The pipe material placed on the load-bearing rod 13 is affected by gravity and moves away from the fixed clamping rod 2, so that the pipe material on the load-bearing rod 13 between the movable clamping rod 3 and the fixed clamping rod 2 is automatically cleaned, which is convenient for untying the next bundled material.

[0041] In this embodiment, the placement rack is used to place the bundled material. After the bundled pipe material is placed on the placement rack, the driving device 4 drives the movable clamping rod 3 to move, so that the movable clamping rod 3 moves towards the direction close to the fixed clamping rod 2, so that the bundled material is clamped by the fixed clamping rod 2 and the movable clamping rod 3. The clamped bundled material will shrink, so that the elastic force on the binding belt disappears. When the worker cuts the binding belt, the binding belt will not bounce at this time because there is no elastic force, so as to prevent the rebounding binding belt from hurting the operating worker.

[0042] Example 2: Refer to Figures 1 to 4 As shown in the figure, a tube bundle unpacking device includes: a placement rack for placing the bundled materials. The placement rack includes a number of parallel load-bearing racks 11, and adjacent load-bearing racks 11 are connected by connecting rods 12 to form the entire structure of the placement rack. Two parallel load-bearing rods 13 are provided on each load-bearing rack 11. When the bundled materials are placed on the load-bearing rods 13, the tubes are perpendicular to the load-bearing rods 13.

[0043] On one side in the width direction of the placement rack, a number of fixed clamping rods 2 are provided, and on the other side in the width direction of the placement rack, a number of movable clamping rods 3 are provided. A number of driving devices 4 drive the movable clamping rods 3 to reciprocate towards the fixed clamping rods 2.

[0044] In this embodiment, the fixed clamping rods 2 are fixedly arranged at one end of the load-bearing rods 13, and the movable clamping rods 3 are in a non-working state at the lower end of the load-bearing rods 13. The number of fixed clamping rods 2 is the same as the number of load-bearing racks 11, and the number of movable clamping rods 3 is the same as the number of fixed clamping rods 2, and each movable clamping rod 3 and its corresponding fixed clamping rod 2 are arranged in the same transverse direction of the placement rack.

[0045] The movable clamping rods 3 and the driving devices 4 are installed between the two load-bearing rods 13. One end of the movable clamping rod 3 is connected to the driving device 4. The driving device 4 uses a hydraulic cylinder, which can provide sufficient driving force to drive the movable clamping rod 3 to rotate. The driving device 4 includes but is not limited to a hydraulic cylinder. The other end of the movable clamping rod 3 is provided with a bent rod 31; a rotating hole 32 is provided between the connection point of the movable clamping rod 3 and the driving device 4 and the bent rod 31. A rotating shaft 14 is fixedly arranged on the placement rack, and the rotating shaft 14 is arranged below the load-bearing rods 13, and the rotating hole 32 rotates around the rotating shaft 14.

[0046] In the non-working state, the movable clamping rod 3 is located at a position below the upper end surface of the load-bearing rod 13, which does not affect the placement of the bundled materials. When it is necessary to untie the bundled materials, the hydraulic cylinder drives its movable end to drive the movable clamping rod 3 to move, so that the movable clamping rod 3 rotates around the rotating shaft 14, so that the bent rod 31 rotates towards the direction close to the fixed clamping rod 2. The setting of the bent rod 31 enables it to cooperate better with the fixed clamping rod 2, so that the bundled materials can be clamped more stably, so that the tubes are compressed, and the straps tied to the bundled materials contract, and the elastic force on the straps disappears. After the strap is cut, the strap will not rebound. Then the movable clamping rod 3 is reset under the action of the hydraulic cylinder, and the movable clamping rod 3 returns below the load-bearing rod 13, so that the tubes are placed on the load-bearing rack 11 and wait for further processing.

[0047] The load-bearing rod 13 is inclined away from the fixed clamping rod 2. That is to say, the height of the load-bearing rod 13 at the movable clamping rod 3 is lower than the height of the load-bearing rod 13 at the fixed clamping rod 2. Thus, the cylindrical pipe material can automatically roll downward along the load-bearing rod 13. After rolling down from the load-bearing rod 13, the pipe material can be processed in the next step, so that the pipe material in the area of the load-bearing rod 13 between the fixed clamping rod 2 and the movable clamping rod 3 is automatically emptied from this area.

[0048] The linear distance from the rotation hole 32 to the end of the bending rod 31 is L1, and the linear distance from the rotation hole 32 to the connection point of the driving device 4 and the movable clamping rod 3 is L2, and L1 is greater than L2. Since one end of the bending rod 31 needs to clamp the bundled material, the lever arm of one end of the bending rod 31 is set longer, so that the pipe material can be clamped more stably, and it also enables the hydraulic rod to move a very small stroke to make the movable clamping rod 3 rotate a larger angle.

[0049] Refer to Figure 4 As shown, the number of the driving devices 4 is less than the number of the movable clamping plates. The ends of several movable clamping rods 3 away from the bending rod 31 are connected by a connecting rod 5. In this embodiment, the number of the movable clamping rods 3 is four, and the driving devices 4 are set to two. The ends of the movable clamping rods 3 away from the bending rod 31 are all hinged to the connecting rod 5. So that all the movable clamping rods 3 can be driven to move by two driving devices 4 or even one driving device 4.

[0050] The working principle of this embodiment is as follows: First, place the bundled material on the placement rack. At this time, the pipe material is perpendicular to the load-bearing rack 11. Then the hydraulic cylinder is started, and the movable end of the hydraulic cylinder drives the movable clamping rod 3 to rotate, so that the movable clamping rod 3 rotates. When the movable clamping rod 3 rotates, the bending rod 31 moves towards the direction close to the fixed clamping rod 2. Then the fixed clamping rod 2 and the movable clamping rod 3 cooperate to clamp the bundled material. After the bundled material is clamped, the elastic force on the binding belt of the bundled material weakens or disappears. Then the worker cuts the binding belt, and at this time the binding belt will not rebound. The pipe material in the bundled material spreads out between the fixed clamping plate and the movable clamping plate. Then the hydraulic cylinder drives the movable clamping rod 3 to reset, and the movable clamping rod 3 resets below the load-bearing rod 13 again, and the pipe material is placed on the load-bearing rod 13.

[0051] The pipe material placed on the load-bearing rod 13 is affected by gravity and moves away from the fixed clamping rod 2, so that the pipe material on the load-bearing rod 13 between the movable clamping rod 3 and the fixed clamping rod 2 is automatically cleaned, which is convenient for untying the next bundled material.

[0052] In this embodiment, the placement rack is used to place the bundled materials. After the bundled pipe materials are placed on the placement rack, the driving device 4 drives the movable clamping rod 3 to move, so that the movable clamping rod 3 moves towards the direction close to the fixed clamping rod 2, and the bundled materials are clamped by the fixed clamping rod 2 and the movable clamping rod 3. The clamped bundled materials will shrink, so that the elastic force on the binding belt disappears. When the worker cuts the binding belt, the binding belt at this time will not bounce because there is no elastic force, thus preventing the rebounding binding belt from hurting the operating worker.
