Description

Technical Field

[0001] The utility model belongs to the technical field of transfer platforms, and particularly relates to a transfer platform for large-diameter steel pipes at workstations. Background Art

[0002] After the winding film operation of external anti-corrosion of large-diameter steel pipes, according to the design requirements of the products, they are either sent to the finished product warehouse or transferred to workstations such as spraying. However, due to the large size and heavy mass of large-diameter steel pipes themselves, it is extremely inconvenient to transfer them.

[0003] In view of this situation, in the prior art, a combination of a lever and a rack platform is used. The large-diameter steel pipe rolls on the rack platform, and the lever determines the rolling direction of the large-diameter steel pipe. The lever is generally arranged in parallel with the rotating wheel bracket for placing the large-diameter steel pipe. The lever is in a √ shape as a whole. The end of the long arm is hinged to the rack. A vertical hydraulic push rod is arranged at the bottom of the lever. The lever is lifted by the hydraulic push rod, and then the lever contacts the large-diameter steel pipe and guides it to the adjacent rack.

[0004] However, this kind of lever can only push the large-diameter steel pipe in one direction. If it is necessary to push the large-diameter steel pipe in the opposite direction, a mirror lever needs to be installed beside the existing lever to achieve two-way pushing of the large-diameter steel pipe. However, the above structure has many disadvantages, such as complex structure, large occupied space, and complex hydraulic system (either two sets of hydraulic systems are set up to drive respectively, or one set of hydraulic system realizes separate driving through multiple valve bodies), etc. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a transfer platform for large-diameter steel pipes at workstations, which is used to solve the technical problems that the transfer device structure and hydraulic system of large-diameter steel pipes in the prior art are both relatively complex, resulting in an increase in equipment cost and maintenance difficulty.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: A transfer platform for large-diameter steel pipes at workstations, comprising:

[0007] A lifting station, one end of the lifting station faces the previous workstation. The lifting station includes a plurality of lifting components and a plurality of rotating wheel brackets, and the lifting components and the rotating wheel brackets are arranged at intervals;

[0008] Two rack platforms, the two rack platforms are respectively arranged on both sides of the lifting component and respectively correspond to different subsequent workstations;

[0009] The lifting component includes:

[0010] A pair of support columns, and the pair of support columns are respectively arranged on both sides;

[0011] The first lifting link, wherein the first lifting link is pivotally connected to one of the support columns;

[0012] The second lifting link, wherein the second lifting link is pivotally connected to the first lifting link, and the second lifting link is pivotally connected to the other support column;

[0013] The hydraulic jack is arranged below the first lifting link or the second lifting link.

[0014] The utility model forms a V-shaped structure by using the first lifting link and the second lifting link. When a large-diameter steel pipe needs to be transferred to other workstations, only the hydraulic jack needs to lift the first lifting link and the second lifting link to the horizontal, and then push the large-diameter steel pipe to the workstation where it needs to be transferred.

[0015] Further: The pivot hole at any one of the pivot joints between the first lifting link and the second lifting link, the pivot joint between the first lifting link and the support column, and the pivot joint between the second lifting link and the support column is an oval hole, and a pivot shaft is arranged in the oval hole.

[0016] The beneficial effect of adopting this step: It can be known from the triangle formed by the three pivot joints that the sum of the two sides of the triangle is greater than the third side, indicating that the length of the first lifting link and the second lifting link in the V-shaped structure is greater than that in the horizontal state. In order to eliminate this length difference, oval holes are arranged at the pivot joints.

[0017] Further: The first lifting link and the second lifting link are channel steels with the opening facing upwards;

[0018] The groove of the channel steel is filled with wooden squares.

[0019] The beneficial effect of adopting this step: The main purpose is to reduce weight.

[0020] Further: Rubber pads are laid on the top surfaces of the first lifting link and the second lifting link.

[0021] The beneficial effect of adopting this step: Prevent damage to the anti-corrosion layer on the surface of the large-diameter steel pipe.

[0022] Further: The frame platform includes a plurality of parallel portal frames, and limit protrusions are arranged at the outer ends of the top surfaces of the portal frames.

[0023] The beneficial effect of adopting this step: The limit protrusions prevent the large-diameter steel pipe from rolling down.

[0024] Further: The columns of the portal frame are I-beams or steel pipes;

[0025] When the column is an I-beam, a fixing plate is arranged at the bottom surface, and a strengthening rod is arranged between the portal frames;

[0026] When the upright column is a steel pipe, the diameter range of the steel pipe is 300 - 500 mm.

[0027] Beneficial effect of this step: Different embodiments of the portal frame.

[0028] Further: The top surface of the first lifting link or the second lifting link is provided with a movable convex block.

[0029] Beneficial effect of this step: The convex block has two functions. One is to prevent the large-diameter steel pipe from rolling to the wrong position, and the other is to guide the rolling direction of the large-diameter steel pipe.

[0030] The beneficial effect of the present utility model is:

[0031] Using the lifting assembly composed of two links to replace the lever in the prior art to achieve the purpose of controlling the two-way rolling of the large-diameter steel pipe with a simple structure, simplifying the mechanical structure and hydraulic structure of the transfer platform, etc., achieving the effects of reducing costs and reducing maintenance difficulties.

[0044] Embodiment

[0045] As Figure 1 and Figure 2 shown, a large-diameter steel pipe working position transfer platform provided by this utility model includes:

[0046] A lifting station, one end of which faces the front station, and the lifting station includes a plurality of lifting assemblies and a plurality of rotating wheel brackets 1, and the lifting assemblies and the rotating wheel brackets 1 are arranged at intervals; the front station generally performs anti-corrosion wrapping and other processes on the large-diameter steel pipe 8, and after completion, the rotating wheel bracket 1 is pushed in, and the large-diameter steel pipe 8 is generally supported and rotated by the rotating wheel bracket 1;

[0047] Two rack platforms 2, the two rack platforms 2 are respectively arranged on both sides of the lifting assembly and correspond to different post-process workstations, such as a finished product warehouse or a paint spraying room;

[0048] The lifting assembly comprises:

[0049] A pair of support columns 3, a pair of support columns 3 are respectively arranged on both sides;

[0050] A first lifting link 4, wherein the first lifting link 4 is pivotally connected to one of the support columns 3;

[0051] a second lifting link 5, the second lifting link 5 being pivotally connected to the first lifting link 4, and the second lifting link 5 being pivotally connected to another of the support columns 3;

[0052] A hydraulic jack 6, wherein the hydraulic jack 6 is arranged below the first lifting link 4 or the second lifting link 5;

[0053] When the hydraulic jack 6 is extended to the upper limit, the first lifting link 4 and the second lifting link 5 are in a horizontal state;

[0054] When the hydraulic jack 6 is retracted to the lower limit, the first lifting link 4 and the second lifting link 5 are V-shaped, and the contact position a with the large-diameter steel pipe 8 is lower than the contact position b between the rotating wheel bracket 1 and the large-diameter steel pipe 8 .

[0055] The utility model utilizes the first lifting link 4 and the second lifting link 5 to form a V-shaped structure. When the large-diameter steel pipe 8 needs to be transported to other workstations, it only needs the hydraulic jack 6 to push the first lifting link 4 and the second lifting link 5 to a horizontal level, and then push the large-diameter steel pipe 8 to the workstation that needs to be transported.

[0056] The utility model no longer needs to repeatedly and massively use a shifting lever in a single direction, thereby simplifying the mechanical structure and the structure of the hydraulic power system, achieving the purpose of reducing costs and reducing the difficulty of daily maintenance.

[0057] On the basis of the above technical solution, the pivot hole at any one of the pivot joints of the first lifting link 4 and the second lifting link 5, the pivot joint of the first lifting link 4 and the support column 3, and the pivot joint of the second lifting link 5 and the support column 3 is a waist-shaped hole, and a pivot shaft is provided in the waist-shaped hole.

[0058] From the triangle formed by the three pivot joints, it can be known that the sum of the lengths of two sides of a triangle is greater than the length of the third side. This indicates that the lengths of the first lifting link 4 and the second lifting link 5 in the V-shaped structure are greater than those in the horizontal state. To eliminate this length difference, oblong holes are provided at the pivot joints.

[0059] In addition, the pivot joints of the first lifting link 4 and the second lifting link 5 are of a slot structure, that is, a notch is provided at the end of one link, and the end of the other link extends into this notch and then is pivotally connected. This ensures that the first lifting link 4 and the second lifting link 5 are in the same plane, which can save space.

[0060] Based on the above technical solution, the first lifting link 4 and the second lifting link 5 are channel steels with the opening facing upwards;

[0061] Wooden squares are filled in the grooves of the channel steels.

[0062] The main purpose of the above structure is to reduce the weight of the link itself and lower the power consumption of the hydraulic jack.

[0063] Based on the above technical solution, rubber pads are laid on the top surfaces of the first lifting link 4 and the second lifting link 5.

[0064] The rubber pads play a buffering role to prevent damage to the anti-corrosion layer on the surface of the large-diameter steel pipe 8.

[0065] Based on the above technical solution, the frame platform 2 includes a number of parallel gantry frames, and limit protrusions 21 are provided at the outer ends of the top surfaces of the gantry frames.

[0066] The limit protrusions 21 prevent the large-diameter steel pipe 8 from rolling down.

[0067] Based on the above technical solution, the columns of the gantry frames are I-beams or steel pipes;

[0068] When the columns are I-beams, fixing plates are provided at the bottom surfaces, and strengthening bars are provided between the gantry frames;

[0069] When the columns are steel pipes, the diameter range of the steel pipes is 300 - 500 mm.

[0070] Different embodiments of the gantry frames.

[0071] Based on the above technical solution, movable bumps are provided on the top surfaces of the first lifting link 4 or the second lifting link 5.

[0072] The bumps can have various forms of movable installation. If the link is made of metal, the bumps can be magnetic attraction blocks. If the link is made of other materials, concave holes can be provided on the top surface of the link for placing the bumps.

[0073] The bump has two functions. One is to prevent the large-diameter steel pipe 8 from rolling to the wrong position, and the other is to guide the rolling direction of the large-diameter steel pipe 8 during the lifting of the connecting rod.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
