Description

Technical Field

[0001] The utility model relates to the technical field of clamping table equipment, in particular to a pipe clamping and transporting device. Background Art

[0002] Special-shaped pipes refer to pipes with unconventional shapes, which are usually different from standard round straight pipes, such as "U-shaped" pipes that contain symmetrical straight pipe sections and arc-shaped curved pipe sections.

[0003] The shapes of these special-shaped pipes vary, and when the size of some parts changes, the overall size changes greatly. Take the "U-shaped" pipe as an example. When the radius of the curved section changes, the "U-shaped" pipe as a whole will change significantly in the width direction. When carrying large-sized special-shaped pipes, they are usually affected by their own shape and size, and require the joint efforts of multiple people to carry them.

[0004] In the current market, there is a further demand for special-shaped pipes, such as requiring the outer wall of the special-shaped pipe to be provided with a large number of fins, etc. However, when such special-shaped pipes are manually transported, it is easy to cause bumps, scratches, etc. on the additional parts such as the fins.

[0005] If mechanical grasping and carrying of special-shaped pipes is adopted, the above-mentioned problems can be partially solved, but currently there is a lack of relevant desktop equipment on the market that can grasp and carry the above-mentioned special-shaped pipes stably. Utility Model Content

[0006] The utility model provides a pipe clamping and handling device for clamping a special-shaped pipe including two symmetrically distributed pipe sections. The pipe clamping and handling device can reduce the manpower consumption in the handling process, and after mechanical handling control, it can reduce the damage caused by manual handling, such as bumps and scratches.

[0007] The utility model is realized through the following technical solutions.

[0008] A pipe clamping and handling device is used for clamping and handling special-shaped pipes. The special-shaped pipe is characterized in that it comprises two symmetrically distributed pipe sections.

[0009] No matter what shape of pipe is used to connect the two straight pipe sections, as long as the two pipe sections are symmetrically distributed, they can be applied to the pipe clamping and handling device. Taking a "U-shaped" pipe as an example, one end of the two straight pipe sections is connected to the two ends of the arc-shaped curved pipe, so that the "U-shaped" pipe is an axisymmetric structure as a whole, and the two straight pipe sections on it are symmetrically distributed. This "U-shaped" pipe can be applied to the pipe clamping and handling device.

[0010] The pipe clamping and handling device is characterized in that it comprises:

[0011] A clamping part, used for clamping the special-shaped pipe;

[0012] A moving part, used for defining a moving path of the clamping part, so as to realize the handling of the special-shaped pipe;

[0013] The positioning part is used to limit and adjust the working position of the clamping part to ensure that the clamping part can accurately clamp the special-shaped pipe, and includes a positioning component arranged on the moving part and a positioning block arranged on the processing platform, and the positioning component is adapted to the positioning block.

[0014] In the usual processing flow, firstly, the complete special-shaped pipe is processed on the processing platform. Then the special-shaped pipe on the processing platform needs to be moved to the designated material rack and moved to other stations for cleaning, inspection, water pressure test, etc. Therefore, the processing platform is the initial platform for supporting special-shaped pipes, and the pipe clamping and handling work starts from the processing platform.

[0015] In the process of clamping and handling pipes, the initial working position of the clamping part needs to be adjusted by the moving part, and the clamping working position of the clamping part needs to be determined by the positioning part. After ensuring that the clamping part is located at the designated clamping working position, the special-shaped pipe is clamped and adjusted to the final working position by the moving part. Finally, the clamped special-shaped pipe is released to complete a handling work.

[0016] When the handling device completes a handling task, it needs to move the clamping part back to the location of the processing platform to clamp the next set of special-shaped pipes. At this time, the overall position of the pipe clamping and handling device does not have a large deviation, but in order to ensure that the clamping part on it can successfully clamp the special-shaped pipe, the position needs to be calibrated. When the positioning part on the handling device matches the positioning block on the processing platform, it means that the position of the pipe clamping and handling device is accurate and the next clamping and handling work can be carried out.

[0017] In order to make the positioning component adapt to the positioning block, the structures that can be used include but are not limited to: a accommodating space is provided on the positioning component, and when the accommodating space completely accommodates the positioning block, the positioning is successful; the positioning component includes two clamping blocks, and when the clamping blocks are retracted toward the center and clamp the positioning block, the positioning is successful, and any other mechanical structure that fixes the relative position of the positioning component and the positioning block.

[0018] As a further improvement of the present invention, the moving part includes a lifting arm and a transverse beam; the clamping part and the positioning assembly are arranged on the transverse beam; wherein the lifting arm is used to adjust the position of the transverse beam and its upper parts in the vertical direction, and the transverse beam is used to adjust the position of the clamping part and the positioning part in the horizontal direction.

[0019] Since the processing platform is responsible for the initial processing and manufacturing of special-shaped pipes, a fixing device is usually provided on the processing platform to prevent the pipes from shifting during processing. Plastic buckles are usually used to fix the pipes and facilitate the removal of the pipes.

[0020] Therefore, after clamping the special-shaped pipe, the pipe clamping and handling device usually removes the special-shaped pipe from the processing platform by lifting it up with a lifting arm, and then moves the special-shaped pipe in a horizontal position to the designated area above the material rack through the transverse beam, and then moves it under the special-shaped pipe, and finally releases the special-shaped pipe to complete the handling work.

[0021] As a further improvement of the present invention, the clamping portion includes two clamping members, and the two clamping members are symmetrically distributed on the transverse beam along the central reference line of the transverse beam; the moving portion also includes a spacing adjustment device for adjusting a first spacing between the two clamping members.

[0022] In the present invention, all center reference lines refer to a reference line used to determine or mark the position of other structures or components. The line is located at the center of the structure or equipment and can be used as a reference for other measurements or positioning.

[0023] Here, the center reference line of the transverse beam refers to a reference line passing through the center of the transverse beam and perpendicular to the longer side of the transverse beam.

[0024] When the size of the special-shaped pipe changes, especially when the size of the pipe segment used to connect the two pipe segments changes, the distance between the two pipe segments will also change. Under this structure, the two clamping members are used to clamp the two pipe segments respectively, so the first distance can be adjusted first to make the first distance close to the distance between the two pipe segments, and then the pipe segments can be clamped after the positioning work is completed. This structure enables the pipe clamping and handling device to clamp and handle special-shaped pipes of different sizes, thereby improving the applicability of the pipe clamping and handling device.

[0025] As a further improvement of the present invention, the positioning assembly is arranged on the central reference line of the transverse beam, and the positioning block is arranged on the central reference line of the processing platform.

[0026] The center reference line of the processing platform here refers to the reference line passing through the center of the processing platform.

[0027] Under this structure, when the special-shaped pipe is placed on the processing platform, the two pipe sections are distributed on both sides of the positioning block and have the same distance from the positioning block.

[0028] At the same time, the positioning component is located on the center reference line of the transverse beam, and the clamping parts are symmetrically distributed on the transverse beam along the center reference line of the transverse beam. At this time, only the first distance between the two clamping parts needs to be adjusted appropriately. When the positioning part and the positioning block jointly complete the positioning work, the two clamping parts can clamp the corresponding pipe sections.

[0029] As a further improvement of the utility model, the positioning assembly includes a first driving device and two movable positioning blocks. When performing positioning work, the first driving device is used to drive the two movable positioning blocks to move toward the position of the center reference line of the transverse beam so that the two movable positioning blocks clamp the positioning block.

[0030] When the movable positioning block clamps the positioning block, it not only determines the position of the transverse beam, but also ensures that the transverse beam is in a horizontal state. At the same time, since the table top of the processing platform is also in a horizontal state, the transverse beam and the table top of the processing platform are relatively parallel at this time.

[0031] After the positioning work is achieved through the positioning assembly and the positioning block, it can be ensured that the two clamping members can completely clamp the entire pipe section, that is, the clamping members clamp the pipe section at the position of the pipe diameter, rather than only clamping part of the pipe section, thereby ensuring the stability of the clamping work and preventing the special-shaped pipe from falling off during subsequent handling.

[0032] As a further improvement of the utility model, the movable positioning block includes a positioning rod, one end of which is fixed on the movable positioning block, and the other end is horizontally away from the main body of the pipe clamping and handling device, and this end is the clamping end; when positioning work is performed, the clamping ends of each of the two positioning rods clamp the positioning block.

[0033] When processing a long pipe section, multiple processing platforms are usually used, each of which can hold a part of the pipe section, and finally multiple parts are spliced ​​together to form a complete pipe section. Accordingly, in order to ensure the stability of transportation, multiple handling devices will also be used to clamp and transport the pipe sections of special-shaped pipes at the same time.

[0034] There are gaps between multiple processing platforms. At this time, when the movable positioning block of this structure is used for positioning, the pipe clamping and handling device can be moved to the space above the gap and then fall down to perform the clamping work, rather than moving to the space above the processing platform and then advancing the clamping work. In this clamping situation, the collision between the bottom of the clamping part and the supporting surface of the processing platform is avoided, and the possibility of damage to the clamping part is reduced while ensuring that the clamping part can clamp the pipe section.

[0035] As a further improvement of the utility model, the positioning part further includes a transverse positioning block fixedly arranged on the transverse beam and two transverse limit blocks arranged on the lifting arm; a second spacing is arranged between the two transverse limit blocks, forming an accommodation space for accommodating the transverse positioning block, so as to limit the transverse movement range of the transverse beam. When the transverse beam moves to the point where the transverse positioning block is supported by one of the transverse limit blocks, the transverse beam is located in the space above the processing platform or the corresponding material rack, and at this time, the lifting arm can be used to move in the vertical direction, perform positioning work, and finally clamp or release the special-shaped pipe.

[0036] As a further improvement of the utility model, a transverse limit block is movably installed on the lifting arm, and when the position of the transverse beam is fixed, the two transverse limit blocks are clamped to the transverse positioning block through the second driving device.

[0037] Under this structure, when the lateral positioning block collides with one of the lateral limit blocks, the other lateral limit block can move, and finally clamp the lateral positioning block. This clamping work can adjust the main body of the lateral beam to a horizontal state before the positioning work after displacement. In the subsequent positioning and clamping work, the lateral beam is guaranteed to be parallel to the supporting surface of the processing platform, so that both clamping parts can stably clamp the special-shaped pipes; in the release work, it is ensured that the special-shaped pipes on the rack are stacked flat when released.

[0038] As a further improvement of the utility model, the clamping member is an air gripping device, which includes two clamping blocks and an air driving device, and the air driving device is used to drive the two clamping blocks to clamp the pipe section. The air gripping device runs fast and can adjust the gripping force by adjusting the air pressure to prevent deformation of the pipe caused by excessive gripping force.

[0039] As a further improvement of the utility model, a supporting block is provided at the bottom of the clamping block to support the special-shaped pipe during the clamping operation to prevent it from falling off;

[0040] A limit rod is arranged between the two clamping blocks, and when clamping, the limit rod is used to limit the final distance between the two clamping blocks, so as to adapt to the clamping of special-shaped pipes with different pipe diameters.

[0041] In this structure, the clamping piece has the basic clamping function to prevent the special-shaped pipe from moving and falling off, while not causing pressure on the pipe. In order to ensure that the pipe can be transported, the support block supports the special-shaped pipe to prevent it from falling off.

[0042] The structure enables the clamping piece to be used for clamping special-shaped pipes with fins without causing damage to the fins.

[0043] The beneficial effects of the utility model include:

[0044] (1) The above-mentioned special-shaped pipes can be clamped and transported by mechanical equipment, which reduces the labor intensity of workers and avoids the possibility of collision and scratching of special-shaped pipes during manual handling;

[0045] (2) By changing the position of the clamping parts, the clamping and handling equipment can be used for clamping and handling special-shaped pipes of different sizes, thereby improving the versatility of the equipment;

[0046] (3) The design of the clamping structure can ensure that the special-shaped pipe is not subjected to great pressure during the clamping process, thereby preventing the special-shaped pipe from being deformed and / or damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0052] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0053] In each embodiment, the special-shaped pipe refers to a pipe comprising two symmetrically distributed pipe sections A. Taking a "U-shaped" pipe as an example, Figure 3 As shown, it includes two symmetrical pipe sections A and an arc-shaped pipe section connected to the straight pipe section. The pipe clamping and handling device (hereinafter referred to as the handling device) can be used to handle such special-shaped pipes.

[0054] In order to facilitate understanding and demonstrate the specific structure of the transport device in each embodiment, a "U-shaped" tube is used as the clamping object. A person skilled in the art can easily draw the following conclusion: any special-shaped tube containing two symmetrical tube sections A is suitable for the transport device.

[0055] Embodiment 1:

[0056] like Figure 1 As shown, the handling device in this embodiment includes a gripping part 1 for gripping the pipe section A, a moving part 2 for limiting and adjusting the moving path of the gripping part 1, and a positioning part 3 for limiting the working position of the gripping part 1. The positioning part 3 includes a positioning component 301 and a positioning block 302.

[0057] The processing of special-shaped pipes is usually completed on processing platform B. After the processing is completed, the special-shaped pipes need to be moved to other workstations for the next step of testing and other work. Therefore, processing platform B is the initial holding platform for special-shaped pipes, and the transportation of special-shaped pipes also starts from processing platform B.

[0058] In order to accurately clamp the special-shaped pipe on the processing platform B, it is necessary to rely on the positioning part 3. In the positioning part 3, the positioning component 301 is arranged on the main body of the handling device, that is, on the moving part 2; the positioning block 302 matched with the positioning component 301 is arranged on the processing platform B. When the two are matched, the positioning of the working position of the clamping part 1 is completed, and the subsequent clamping work can be carried out.

[0059] The operation process of this handling device mainly includes:

[0060] S1. The main position of the clamping portion 1 is adjusted by the moving portion 2, and then the positioning assembly 301 in the positioning portion 3 matches the positioning block 302 to locate the working position of the clamping portion 2;

[0061] S2. When the positioning assembly 301 matches the positioning block 302, the clamping unit 1 is started to clamp the pipe A;

[0062] S3. After the clamping work is completed, the moving portion 2 is started to change the position of the clamping portion 1 to play a role in handling;

[0063] S4. Adjust the clamping part 1 to return to the initial position through the moving part 2 to prepare for the next round of clamping and handling work.

[0064] Preferably, the moving part 2 includes a lifting arm 201 and a transverse beam 202. The transverse beam 202 is installed on the lifting arm 201, and the lifting arm 201 controls the vertical position of the transverse beam 202 as a whole. The transverse beam 202 is installed with the clamping part 1 and the positioning assembly 301. The transverse beam 202 can move in the horizontal direction, thereby driving the components installed thereon to move horizontally. The lifting arm 201 and the transverse beam 202 cooperate with each other, so that the handling work in S3 can include the steps of lifting the special-shaped pipe, moving the special-shaped pipe horizontally, lowering the special-shaped pipe and releasing it; the return work of the clamping part 1 in S4 can include the steps of lifting the transverse beam 202, returning the transverse beam 202 to its position horizontally, and lowering the transverse beam 202 to locate the working position of the clamping part 1 through the positioning part 3.

[0065] Preferably, the clamping portion 1 comprises two clamping members 101, such as Figure 1 As shown, the two clamping members 101 are symmetrically distributed on the transverse beam 202 along the central reference line of the transverse beam 202, and the first distance between the two clamping members 101 can also be adjusted by a distance adjustment device. The adjustment step can be set during the debugging of the transport device, earlier than the formal use step of the transport device.

[0066] When the position of the clamping member 101 is adjusted, the position of the central reference line of the transverse beam 202 is taken as the central position, and the two clamping members 101 are simultaneously moved the same distance in the direction close to or away from the central position. It is ensured that after adjusting the first spacing, the two clamping members 101 still maintain a symmetrical structure. The spacing adjustment device can be in the form of a servo motor driving a synchronous belt, etc., to synchronously and quantitatively control the moving distance of the two clamping members 101.

[0067] Preferably, if Figure 1 As shown, the positioning assembly 301 is arranged on the center reference line of the transverse beam 202, and the positioning block 302 is arranged on the center reference line of the processing platform B. Under this structure, when the positioning assembly 301 matches the positioning block 302, it can ensure that the center reference line of the transverse beam 202 coincides with the center reference line of the processing platform B. At this time, since the two clamping members 101 are symmetrical with respect to the center reference line, and the pipe section A located on the processing platform B is also symmetrical with respect to the center reference line, it is only necessary to accurately adjust the first spacing during the commissioning of the handling device to ensure smooth clamping work.

[0068] Embodiment 2:

[0069] The difference between this embodiment and embodiment 1 is that in this embodiment, Figure 1~2 As shown, the positioning assembly 301 includes a first driving device and two movable positioning blocks 301 - 1 .

[0070] In S4 , after the transverse beam 202 is returned to the corresponding position, the transverse beam 202 is lowered by the lifting arm 201 , so that the positioning assembly 301 matches the positioning block 302 , and the working position of the clamping part 1 is positioned.

[0071] When positioning the working position of the clamping part 1, the first driving device is used to drive the two movable positioning blocks 301-1 to move simultaneously to the position of the center reference line of the transverse beam 202, so that the two movable positioning blocks 301-1 finally clamp the positioning block 302. When the clamping is completed, the working position of the clamping part 1 is successfully positioned.

[0072] Preferably, if Figure 2 As shown, the movable positioning block 301-1 includes a positioning rod 301-1a. One end of the positioning rod 301-1a is fixed to the movable positioning block 301-1, and the other end is horizontally away from the main body of the transport device, wherein the end away from the main body of the transport device is the clamping end.

[0073] When positioning the working position of the clamping part 1 , the clamping ends of the two positioning rods 301 - 1 a clamp the positioning block 302 .

[0074] like Figure 3 As shown, when processing a long pipe segment, multiple processing platforms B are usually used, each of which can support a part of the pipe segment A, and finally multiple parts are spliced ​​together to form a complete pipe segment A. Accordingly, in order to ensure the stability of transportation, multiple handling devices will also be used to clamp the pipe segment A at different positions at the same time and transport the entire special-shaped pipe.

[0075] There are gaps between the multiple processing platforms B. At this time, when the movable positioning block 301-1 of the structure is used to position the working position of the clamping part 1, when the position of the transport device is initially set, it can be adjusted to be placed in the space above the gap. Then, when adjusting the position of the clamping part 1 in S1, the clamping part 1 can be adjusted to be located in the space above the gap and then dropped, rather than being located in the space above the processing platform B. Under this clamping condition, the bottom of the clamping part 1 is prevented from colliding with the supporting surface of the processing platform B, and the possibility of the clamping part 101 colliding with the processing platform B and being damaged is reduced while ensuring that the clamping part 101 can clamp the pipe section A.

[0076] Embodiment 3:

[0077] The difference between this embodiment and embodiments 1~2 is that, in this embodiment, the positioning portion 3 also includes a transverse positioning block 303 fixedly arranged on the transverse beam 202 and two transverse limit blocks 304 arranged on the lifting arm 201; a second spacing is arranged between the two transverse limit blocks 304 to form an accommodating space for accommodating the transverse positioning block 303.

[0078] When the transverse beam 202 moves laterally, when it reaches the space above the position for clamping or placing special-shaped pipes, the transverse positioning block 303 thereon will conflict with one of the transverse limit blocks 304, so that the transverse limit block plays a role in limiting the transverse movement range of the transverse beam 202.

[0079] Preferably, if Figure 1~2 As shown, the transverse limit block 304 is movably installed on the lifting arm 201. When the position of the transverse beam 202 is fixed, the two transverse limit blocks 304 are clamped by the second driving device to clamp the transverse positioning block 303.

[0080] When the transverse positioning block 303 moves to conflict with one of the transverse limit blocks 304, the other transverse limit block 304 can be driven by the second driving device to approach the position of the transverse positioning block 303. Finally, the two transverse limit blocks 304 clamp the transverse positioning block 303 to fix the position of the transverse positioning block 303, that is, to fix the position of the transverse beam 202.

[0081] Embodiment 4:

[0082] The difference between this embodiment and embodiments 1 to 3 is that in this embodiment, Figure 1~2 As shown, the clamping member 101 is an air gripping device, which includes two clamping blocks 101-1 and an air driving device. The air driving device is used to drive the two clamping blocks 101-1 to move toward the center at the same time to clamp the pipe section A during the clamping operation.

[0083] Preferably, if Figure 1 As shown, a supporting block 101-2 is provided at the bottom of the clamping block 101-1, which is used to support the corresponding pipe section A on the special-shaped pipe to prevent it from falling off during the clamping operation; a limiting rod 101-3 is provided between the two clamping blocks 101-1, and the limiting rod 101-3 is used to limit the final spacing between the two clamping blocks 101-1 during the clamping operation.

[0084] The two structures cooperate together, so that the clamping block 101-1 plays a greater role in preventing the pipe segment A from being displaced, and the support block 101-2 is used to ensure that the pipe segment A will not fall off. The two structures cooperate together, so that when clamping the pipe segment A, the clamping member 101 is prevented from exerting a large clamping pressure on the pipe segment A to cause deformation of the pipe segment A, while ensuring that the pipe segment A will not shake or deviate during transportation, so as to prevent it from falling off.

[0085] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
