Description

Technical Field

[0001] The utility model belongs to the technical field of I-beam processing, and in particular relates to a prefabricated anti-overturning device for an I-beam. Background Art

[0002] I-beam is a steel beam with an I-shaped cross-section. It is widely used in the industry, such as as a load-bearing beam in building structures. Since I-beam has a very high compressive strength, it can be used as the support structure of the platform during the construction of the offshore platform. By installing I-beam, the structural stability of the offshore platform can be improved.

[0003] In the production and processing of I-beams, in order to facilitate operation, it is often necessary to raise the I-beam to a height that is convenient for operation, such as a height corresponding to the height of the operator, so that the operator can easily operate the I-beam, such as correction, knocking, welding, etc. However, since the I-beam has a certain length, during the operation, the container may overturn when the I-beam is raised, which may easily injure the construction workers.

[0004] Therefore, during the design and construction process, it is often necessary to arrange support rods to support the two sides of the beam diagonally to play a supporting role. However, due to the relatively long length of the I-beam, during the construction process, when constructing at different parts of the I-beam, especially when force needs to be applied to the beam, the support structure needs to be moved to the vicinity of the operating part, so as to ensure that the I-beam at the operating part is not easily lost due to loss of balance, which will cause the entire beam frame to lose balance.

[0005] Currently, the more conventional operation method is to loosen the locking structure of the diagonal support rod, move the diagonal support rod, and then lock it again. However, during the construction process, since the I-beam has a certain length and the construction position needs to be adjusted back and forth on the I-beam during construction, the repeated disassembly and installation of the support to improve the safety of the operation makes the work efficiency very low and the operation is not convenient enough.

[0041] Example 1

[0042] like Figure 1-5 As shown, a prefabricated anti-overturning device for an I-beam includes an anti-overturning mechanism. The anti-overturning mechanism can be used to prevent the I-beam 1 from losing balance and causing overturning during operation, and can also flexibly adjust the support position according to the construction location (stress-bearing location) of the I-beam 1.

[0043] Specifically, the anti-overturning mechanism includes a first adjusting slide rail 4 and a second adjusting slide rail 3 symmetrically arranged on both sides of the I-beam 1; a plurality of contact wheel assemblies are assembled and connected between the first adjusting slide rail 4 and the second adjusting slide rail 3.

[0044] The contact wheel assembly includes contact wheels symmetrically arranged front and back (the structure of the contact wheel is: the contact wheel includes a wheel frame plate 62, and the wheel frame plate 62 is rotatably connected to a wheel body 61, and the wheel body 61 contacts and rolls on the I-beam 1), and the contact wheels on the front and rear sides respectively contact the two sides of the I-beam 1.

[0045] At the same time, the abutting wheels are respectively hinged with articulated arms 63 (specifically: a pair of articulated ear plates are fixedly connected to the wheel frame plate 62, and the upper end of the articulated arm 63 is hinged between the articulated ear plates through a fixed pin shaft), and the bottom of the articulated arm 63 is hinged with a slide seat 631 (specifically: a pair of ear plates are fixedly connected to the top of the slide seat 631, and the lower end of the articulated arm 63 is hinged between the ear plates through a pin shaft). The slide seat 631 is slidably connected to the first adjustment rail 4 and the second adjustment rail 3.

[0046] Specifically, the slide 631 slides in a limited manner, specifically, the longitudinal cross-section of the slide 631 is T-shaped, and the first adjustment slide rail 4 and the second adjustment slide rail 3 are respectively provided with a slide groove 31 adapted to the slide 631. The front and rear sides of the slide 631 are limited in the slide groove 31 of the T-shaped structure.

[0047] During the working process, the two sides of the I-beam 1 are simultaneously abutted from multiple positions through the multiple abutment wheels-articulated arms 63-slide seats 631 structures on the front and rear sides.

[0048] At the same time, during the working process, if it is necessary to perform forceful work (such as tapping and correction) at a certain position of the I-beam 1, at this time, the resistance wheel-articulated arm 63-slide seat 631 is slid to the vicinity of the working part, thereby increasing the stability of the working part.

[0049] The above method not only realizes the synchronous multiple-position abutment support on both sides of the I-beam 1 in a very flexible manner, but also because the abutment support can be adjusted by rolling, the I-beam 1 can be fully supported during the processing of the I-beam 1, especially during the repeated correction of the I-beam 1, the abutment wheel-articulated arm 63-slide seat 631 structure can be adjusted back and forth, so as to reduce the difficulty of operation and improve the operation efficiency.

[0050] The bottom of the I-beam 1 is supported by a plurality of support columns 2. During operation, the I-beam 1 is supported on the support columns 2 to maintain a certain height for easy operation.

[0051] Example 2

[0052] like Figure 1-5As shown, based on the structure of Example 1, the front and rear ends of the top of the slide seat 631 are respectively fixedly connected with screws 6311, and correspondingly, the first adjustment rail 4 and the second adjustment rail 3 are provided with long rectangular sliding openings adapted to the screw 6311, and the screw 6311 is limited to slide in the long rectangular sliding opening; a contact pressure positioning nut is threadedly connected to the screw 6311.

[0053] During operation, as the resistance wheel-articulated arm 63-slide seat 631 slides and adjusts, the screw 6311 slides in the long rectangular slide. After sliding to the target position, the contact pressure positioning nut is screwed until it is squeezed onto the first adjustment slide rail 4 and the second adjustment slide rail 3 to maintain positioning.

[0054] Example 3

[0055] like Figure 1-5 As shown, based on the structure of Example 1, in order to facilitate the resistance wheel to press against the I-beam 1, the prefabricated anti-overturning device of the I-beam 1 further includes a locking mechanism, through which the resistance wheel is locked to press against the I-beam 1.

[0056] Specifically, the locking mechanism includes a first locking assembly installed between the left end and the right end of the first adjusting slide rail 4 and the second adjusting slide rail 3 .

[0057] Specifically, the first locking assembly comprises convex plates welded to the bottom of the first adjusting slide rail 4 and the second adjusting slide rail 3 , and a long mounting screw 5 is slidably connected between the convex plates.

[0058] Specifically, the front and rear ends of the long mounting screw rod 5 are respectively threadedly connected with push nuts for pushing the first adjusting slide rail 4 and the second adjusting slide rail 3 against each other.

[0059] During the working process, after the pushing nut is pushed inward, the first adjusting slide rail 4 and the second adjusting slide rail 3 on the front and rear sides carry the first adjusting slide rail 4-contact wheel and the second adjusting slide rail 3-contact wheel structure to approach each other, and the contact wheels are pressed against the two sides of the I-beam 1.

[0060] During the abutment process, the articulated arm 63 rotates to a positioning state, in which the abutment wheel abuts against the I-beam 1 and remains fixed.

[0061] Example 4

[0062] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the locking mechanism further includes a second locking assembly installed between the wheel frame plates 62 .

[0063] Specifically, the second locking assembly includes a vertical column 71 fixedly connected to the top position of the wheel frame plate 62, and a long sliding screw 72 is slidably connected between the vertical columns 71; the front and rear ends of the long sliding screw 72 are respectively threadedly connected with an inner push nut that pushes the vertical column 71.

[0064] When the first locking assembly contacts the I-beam 1, the long sliding screw 72 is passed through between the vertical columns 71, and the inner push nut is screwed inward. At this time, when the long sliding screws 72 on both sides are close to each other, the contact wheels are pressed against both sides of the I-beam 1.

[0065] This method can further improve the abutment force of the abutment wheel. When the first locking assembly abuts against the I-beam 1, the long sliding screw 72 on the second locking assembly is disengaged from the vertical column 71 (for easy operation).

[0066] Since the front and rear contact wheels are integrated under the action of the vertical column 71-long sliding screw 72, the contact wheels on both sides can be moved synchronously in this way, which is convenient for synchronous adjustment of the support.

[0067] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
