Description

Technical Field

[0001] The utility model relates to a temporary support, specifically a temporary support for processing mobile metal pipes with variable pipe diameters, mainly used for supporting and placing pipes or for auxiliary support during pipe processing and manufacturing, belonging to the auxiliary technical field of construction supplies. Background Technique

[0002] As is well known, during pipe processing, the use of temporary supports is very important, especially in the processing of metal pipes. The use of pipe support devices is particularly important. During pipe processing, temporary supports can ensure the stability and accuracy of pipes during processes such as cutting, welding, and assembly, thereby improving the quality and efficiency of pipe manufacturing. In addition, during pipe transportation and installation, temporary supports can also be used to support and fix pipes to prevent them from moving or deforming.

[0003] At conventional construction sites, most pipe processing generally does not use temporary supports. Usually, operations are carried out on the ground. This operation method not only makes it difficult to guarantee processing quality, but also requires additional multiple workers to assist beside, performing operations such as lifting, moving, and flipping the pipes. The construction efficiency is extremely low and the safety is poor.

[0004] Currently, although there are already devices in the prior art specifically for supporting and lifting pipes to assist in pipe processing, but currently these existing structures all have relatively complex structures and cumbersome operations during use. When welding and processing pipes with different diameters, manual adjustment of the device needs to be carried out multiple times to achieve. More importantly, after processing, most structures are not equipped with structures convenient for movement. Therefore, it is still necessary to manually carry the temporary support to the designated tool storage location, with low handling efficiency, time-consuming and laborious, increasing the labor intensity of the operator, and the existing structures have large supports, which are difficult to stack or move during placement, and generally, they are very inconvenient.

[0005] Therefore, the key to solving the above technical problems is to develop a temporary support for processing mobile metal pipes with variable pipe diameters that is simple in structure, highly practical, and convenient for stacking and placement. Summary of the Invention

[0024] The inner diameter of the fixed ring (53) is equal to the inner diameter of the fixed sleeve (51);

[0025] The connecting plate (54) is provided with connecting plate connection holes penetrating through its front and back surfaces.

[0026] As a further improvement of the above-mentioned utility model, the support chassis (6) includes:

[0027] A connecting seat (61), the connecting seat (61) includes a connecting sleeve and several first hinge seats circumferentially connected to the outside of the connecting sleeve;

[0028] Several legs (62), one ends of the several legs (62) are respectively hinged to the corresponding first hinge seats;

[0029] Among them, a second hinge seat is further connected to the top of each leg (62) near the connecting seat (61).

[0030] As a further improvement of the above-mentioned utility model, the leg (62) is an integral rectangular plate-shaped member, and a plurality of through holes are also penetrated along the length direction of the leg (62), and one end of the leg (62) is connected to the corresponding first hinge seat through a connecting shaft.

[0031] As a further improvement of the above-mentioned utility model, one end of the connecting rod (7) is connected to the corresponding second hinge seat through a connecting shaft, and the other end is connected to the corresponding connecting plate connection hole below the fixed ring (53) through a connecting shaft.

[0032] As a further improvement of the above-mentioned utility model, the support cylinder (1) includes a support sleeve and a connecting column connected to the middle of the lower end of the support sleeve, and the support sleeve is a columnar structure with an open top and a hollow interior;

[0033] Both the support column (3) and the connecting column are cylindrical structures,

[0034] Among them, the diameter of the support column (3) is larger than the diameter of the connecting column.

[0035] As a further improvement of the above-mentioned utility model, the locking member (2) is arranged on the outer side of the upper part of the support cylinder (1), the locking member (2) includes a knob and a screw rod connected to the middle of one end of the knob, and among them, the fastening member (52) and the locking member (2) have the same shape and structure.

[0036] As a further improvement of the above-mentioned utility model, the supporting jack (4) is integrally in a "V" shape, and a supporting cushion (41) is further connected to the inner side of the supporting jack (4).

[0038] The working principle is as follows: Before using a temporary support for processing a movable metal pipe with variable pipe diameters having the above-mentioned designed structure, a reasonable number of multiple such temporary supports need to be transported to a designated working position for use by manual labor or corresponding handling equipment according to the number of pipes to be processed or the number of workers.

[0039] During use, the operator arranges at least two temporarily adjusted supports side by side and opposite to each other according to the length of the pipe (9) to be specifically processed. After the arrangement is completed, the moving wheels (8) below each temporary support are locked to prevent the temporary support from moving;

[0040] Then, the operator hoists or manually places the pipe (9) into the supporting jacks (4) of the two temporary supports;

[0041] Immediately afterwards, the operator unlocks the moving wheels (8) below each temporary support, and then, under the supporting action of the temporary support, the pipe (9) can be easily moved to the processing area for processing.

[0042] When it is necessary to raise the supporting jack (4), the operator first loosens the locking member (2), and then, when the operator holds the supporting jack (4) and pulls it up to the designated height, the operator locks the support column (3) through the locking member (2), thus completing the work of raising the supporting jack (4).

[0043] When it is necessary to retract the supporting chassis (6) or raise the supporting chassis (6), the operator first loosens the fastening member (52), and then, the operator retracts the supporting chassis (6) downward. During the retraction, the connecting seat (61) drives the connecting rod (7) hinged thereto to move respectively, and further drives the sliding adjustment seat (5) hinged to the other end of the connecting rod (7) to move downward along the lower section of the support cylinder (1). After the retraction is completed, the operator locks the sliding adjustment seat (5) through the fastening member (52), thus completing the retraction of the supporting chassis (6) and the raising of the temporary support.

[0044] When adjusting the height of the pipeline (9) as described above, it can be adjusted in two ways, making the adjustment more convenient and flexible. In addition, a scale is provided on the connecting column of the support column (3) and the lower section of the support cylinder (1), which is more convenient for adjusting the temporary support of the common pipeline (9).

[0045] During the above processing, the operator can adjust the height by adding a new temporary support and reducing the height of the original temporary support. After the height adjustment is completed, reduce the height of the newly added temporary support and remove the newly added temporary support. The pipeline (9) can then be placed on the originally adjusted temporary support to avoid the situation where the lifting equipment is difficult to lift due to environmental factors.

[0046] During the above use process, since the support cushion (41) is connected to the inner side of the support top bracket (4), it can effectively protect the integrity of the pipeline (9).

[0047] Finally, as time goes by, after all the pipelines (9) are processed, the operator only needs to clean and repair the various components of the present utility model, then release the brake device on the moving wheels (8), and then transport it to the designated tool storage warehouse for storage through the moving wheels (8).

[0048] The beneficial effects of the present utility model compared with the prior art are as follows:

[0049] 1. The support top bracket (4) of the present utility model can adjust the height in the upper part of the support cylinder (1) under the mutual cooperation of the support column (3) and the locking member (2) to meet the processing requirements of the operator for pipelines (9) of different heights. At the same time, the pipeline (9) can be locked at the support height in the support cylinder (1) through the locking member (2);

[0050] 2. The fixed adjustment seat (5), the support chassis (6) and the connecting rod (7) of the present utility model are combined with each other, and can expand and contract in the lower section of the support cylinder (1) to realize the rapid support and storage of the temporary support, making the whole support convenient to carry and store, easy to handle, time-saving and labor-saving;

[0051] 3. The fixed adjustment seat (5), the support chassis (6) and the connecting rod (7) of the present utility model are combined with each other, and can adjust the height in the lower section of the support cylinder (1) to realize a certain flexible adjustment of the height of the whole support, providing the ability of fine adjustment during installation and operation, and achieving the optimization of the performance and safety of the equipment.

[0053] 5. An inner side of the support jack (4) of the present utility model is further connected with a support cushion (41), which can prevent the outer wall of the pipeline (9) from being worn during placement and processing, and effectively protect the integrity of the pipeline (9);

[0054] 6.

[0104] In summary, a more specific implementation manner of the present utility model is as follows:

[0105] Before using the temporary support for processing a mobile metal pipeline with variable pipe diameters having the above - designed structure, a reasonable number of multiple such temporary supports need to be transported to the designated working position by manual labor or corresponding handling equipment according to the number of pipelines to be processed or the number of workers for use.

[0106] During use, the operator, according to the length of the pipeline 9 to be specifically processed, places at least two adjusted - height temporary supports side - by - side and relatively. After placing them, the moving wheels 8 below each temporary support are locked to prevent the temporary support from moving;

[0107] Then, the operator hoists or manually places the pipeline 9 into the support top brackets 4 of the two temporary supports;

[0108] Immediately afterwards, the operator unlocks the moving wheels 8 below each temporary support, and then, under the support of the temporary support, the pipeline 9 can be easily moved into the processing area for processing.

[0109] When it is necessary to raise the support top bracket 4, the operator first loosens the locking member 2. Then, the operator holds the support top bracket 4 and pulls it up to the designated height. After that, the operator locks the support column 3 through the locking member 2, thus completing the work of raising the support top bracket 4.

[0110] When it is necessary to fold up the support chassis 6 or raise the height of the support chassis 6, the operator first loosens the fastener 52. Subsequently, the operator folds the support chassis 6 downward. When folding, the connecting seat 61 drives the connecting rod 7 hinged thereto to move respectively, and then drives the sliding adjustment seat 5 hinged to the other end of the connecting rod 7 to move downward along the lower section of the support cylinder 1. After folding is completed, the operator locks the sliding adjustment seat 5 through the fastener 52, that is, the folding of the support chassis 6 and the height adjustment of the temporary support are completed.

[0111] When adjusting the height of the pipeline 9 as described above, it can be adjusted in two ways, making the adjustment more convenient and flexible. In addition, a scale is also provided on the connecting column of the support column 3 and the lower section of the support cylinder 1, which is more convenient for adjusting the temporary support of the common pipeline 9.

[0112] During the above processing, the operator can adjust the height by adding a new temporary support and lower the height of the original temporary support. After the height adjustment is completed, lower the height of the newly added temporary support and remove the newly added temporary support, then the pipeline 9 can be placed on the original temporary support with the adjusted height, avoiding the situation that the lifting equipment is not easy to lift due to environmental factors.

[0113] During the above use process, since a support cushion 41 is connected to the inner side of the support top bracket 4, it can effectively protect the integrity of the pipeline 9.

[0114] Finally, as time goes by, when all the pipelines 9 are processed, the operator only needs to clean and repair the various components of the present utility model, then unlock the braking device on the moving wheels 8, and then transport it to the designated tool storage warehouse for storage through the moving wheels 8.

[0115] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model, and is not a limitation of the present utility model in other forms.
