Description

Technical Field

[0001] This invention relates to the technical field of crane beam installation, specifically to a crane beam system and installation method for factory buildings. Background Technology

[0002] Crane beams are roadbeds that support the operation of gantry cranes and are mostly used in factories. Crane beams have crane tracks on them, and gantry cranes travel back and forth on the crane beams via the tracks. Crane beams are similar to steel beams, but the difference is that the web plates of crane beams are welded with dense stiffening plates to provide support for lifting gantry cranes to move heavy objects.

[0003] The existing patent CN202210827911.6, entitled "A Factory Crane Beam System," describes an installation method for a factory crane beam system. The steps are as follows: multiple logs (1) are set on the ground; the crane beam (2) is hoisted onto the logs (1); an auxiliary truss (3) is erected and hoisted onto the logs (1); a horizontal support (4), a cross support (5), and a walkway plate (6) are connected between the crane beam (2) and the auxiliary truss (3); after the center and elevation of the upper plane of the steel column shoulder beam (7) are verified to be acceptable, a support plate (9) is installed, which is placed on a pad (8); the crane beam system is hoisted at four points, moving the crane beam system to the steel column shoulder beam (7) for installation. The method and system described in this invention not only improve the construction efficiency of the factory crane beam system installation and reduce construction costs, but also reduce high-altitude operations and installation risks.

[0004] The aforementioned existing technical solution has the following drawbacks: In this technical solution, during the installation process, it is not possible to quickly align the crane beam with the mounting bolt holes on the mounting support plate. When using external hoisting equipment to place the crane beam on the mounting support plate, the alignment between the mounting bolt holes requires the cooperation of both manual labor and hoisting equipment to support and lower the crane beam suspended in mid-air to help align the mounting bolt holes. The alignment process is slow, which reduces the overall installation efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a factory crane beam system and installation method, which has the following advantages: automatic alignment of mounting screw holes is achieved through the setting of alignment grooves, negative magnets and positive magnets, which greatly saves the alignment time of mounting screw holes during the installation process, thereby effectively improving the overall installation efficiency.

[0006] The above-mentioned objective of the present invention is achieved through the following technical solution:

[0007] A factory crane beam system includes a support base plate, an I-beam crane beam, and an L-shaped connecting steel plate. The support base plate has an alignment groove at its top, and first mounting slots are formed on both sides of the inner wall of the alignment groove. Positive magnets are fixedly installed inside each of the two first mounting slots. Two alignment support legs are fixedly connected to the bottom of the I-beam crane beam. Second mounting slots are formed on the sides of the two alignment support legs that are close to each other. Negative magnets are fixedly connected inside each of the two second mounting slots. A plurality of mounting screw holes are formed at the bottom of the I-beam crane beam and at the top of the support base plate, and first mounting bolts are threaded into the interior of each of the mounting screw holes.

[0008] In a preferred embodiment, the present invention may be further configured such that: the support plate has an inner cavity for mounting, the bottom of the inner cavity has a groove, and a clamping assembly is installed inside the inner cavity.

[0009] In a preferred embodiment, the present invention may be further configured such that: the clamping assembly includes a bidirectional threaded rod and two clamping steel plates, the bidirectional threaded rod is rotatably mounted inside the mounting cavity, and the bidirectional threaded rod is threadedly connected to a movable bar.

[0010] In a preferred embodiment, the present invention may be further configured such that: the two clamping steel plates are respectively installed at the bottom of the two moving bars, and the interior of each of the two clamping steel plates is threaded with a second mounting bolt.

[0011] In a preferred embodiment, the present invention can be further configured such that: two filling holes are provided on one side of the support plate, and oil storage chambers are provided inside the two moving strips.

[0012] In a preferred embodiment, the present invention can be further configured such that: two annular oil-coated cotton layers are fixedly connected to the inner sides of the two moving strips, and a sealing plug is provided inside the two oil storage cavities.

[0013] In a preferred embodiment, the present invention can be further configured such that: the inner surfaces of the two oil storage chambers are provided with a plurality of oil outlet holes, and the L-shaped connecting steel plate is internally threaded with a third mounting bolt.

[0014] In a preferred embodiment, the present invention may be further configured such that: the internal structure of the I-beam crane beam is fixedly connected with several stiffening ribs, and the top of the I-beam crane beam is provided with a braking truss.

[0015] An installation method for a factory crane beam system includes the following steps:

[0016] S1: Drive the bidirectional threaded rod to rotate through the drive device, drive the moving bar to move until the clamping steel plate clamps the support column;

[0017] S2: Place the support leg at the bottom of the I-beam crane beam on the top of two adjacent alignment grooves. The support leg is attracted by the negative magnet and the positive magnet in the alignment groove to achieve the alignment of the I-beam crane beam and the support base plate. Then, install it in the corresponding mounting screw hole with the first mounting bolt to complete the installation alignment of the I-beam crane beam and the support base plate.

[0018] S3: Align one of the third mounting bolts on the L-shaped connecting steel plate with the mounting screw hole of the I-beam crane beam to fix the I-beam crane beam and the L-shaped connecting steel plate. Align the other third mounting bolt with the screw hole on the support column to fix the I-beam crane beam to the support column. The brake truss is fixed to the I-beam crane beam with bolts to complete the installation.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] The alignment groove allows the alignment support leg to fall in firmly and quickly. The negative magnet and the opposite positive magnet attract each other, making the alignment support leg fit tightly in the alignment groove, thus completing the automatic alignment of the mounting screw hole. This greatly saves the alignment time of the mounting screw hole during the installation process, thereby effectively improving the overall installation efficiency. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, this technical solution discloses a factory crane beam system, including a support base plate 1, an I-beam crane beam 2, and an L-shaped connecting steel plate 3. The top of the support base plate 1 has an alignment groove 4, which allows the alignment support legs 7 to fall in stably and quickly. Both sides of the inner wall of the alignment groove 4 have first mounting slots 5, and positive magnets 6 are fixedly installed inside each of the two first mounting slots 5. Two alignment support legs 7 are fixedly connected to the bottom of the I-beam crane beam 2. Second mounting slots 8 are formed on the sides of the two alignment support legs 7 that are close to each other. Negative magnets 9 are fixedly connected inside each of the two second mounting slots 8. The negative magnets 9 and their opposite positive magnets 6 attract each other, causing the alignment support legs 7 to fit tightly into the alignment grooves 4, completing the automatic alignment of the mounting screw holes 10. Several mounting screw holes 10 are formed at the bottom of the I-beam crane beam 2 and at the top of the support base plate 1, and first mounting bolts 11 are threaded into the interior of each of the mounting screw holes 10.

[0029] The support plate 1 has an internal mounting cavity 12, and a sliding groove 13 is formed at the bottom of the mounting cavity 12. A clamping assembly 14 is installed inside the mounting cavity 12. The clamping assembly 14 includes a bidirectional threaded rod 1401 and two clamping steel plates 1402. The bidirectional threaded rod 1401 is rotatably mounted inside the mounting cavity 12 and is threadedly connected to a moving bar 1403. The two clamping steel plates 1402 are respectively installed at the bottom of the two moving bars 1403, and each of the two clamping steel plates 1402 is threadedly connected to a second mounting bolt 1404.

[0030] Two filling holes 15 are provided on one side of the support plate 1, and oil storage chambers 16 are provided inside the two moving bars 1403. Two annular oil-coated cotton layers 17 are fixedly connected to the inner side of the two moving bars 1403, and sealing plugs 18 are provided inside the two oil storage chambers 16. Several oil outlet holes 19 are provided on the inner surface of the two oil storage chambers 16, and a third mounting bolt 20 is threaded inside the L-shaped connecting steel plate 3. Several stiffening ribs 21 are fixedly connected inside the I-beam crane beam 2, and a braking truss 22 is provided on the top of the I-beam crane beam 2. To prevent the outer surface of the bidirectional threaded rod 1401 from becoming dulled over time and affecting the efficiency of the moving strip 1403, the sealing plug 18 is removed through the filling hole 15, and lubricating oil is injected into the oil reservoir 16. The lubricating oil wets the annular oil-coated cotton layer 17 through the oil outlet hole 19. The bidirectional threaded rod 1401 is rotated by an external drive device. The bidirectional threaded rod 1401 drives the two moving strips 1403 to move on its outer surface. The moving strips 1403 then drive the two annular oil-coated cotton layers 17 to fully coat the outer surface of the bidirectional threaded rod 1401 with lubricating oil, preventing the outer surface of the bidirectional threaded rod 1401 from becoming dull and affecting its use.

[0031] An installation method for a factory crane beam system includes the following steps:

[0032] S1: Drive the bidirectional threaded rod 1401 to rotate by having one end of the external drive device inserted into the connecting groove of the fixing button at one end of the bidirectional threaded rod 1401. This causes the two moving bars 1403 to move closer to each other until the clamping steel plate 1402 is clamped on both sides of the support column. The clamping steel plate 1402 is then fixedly installed on the support column by the second mounting bolt 1404.

[0033] S2: Place the alignment support leg 7 at the bottom of the I-beam crane beam 2 on the top of two adjacent alignment grooves 4. The alignment support leg 7 slides naturally into the alignment groove 4 by its own weight. Then, the negative magnet 9 and its corresponding positive magnet 6 attract each other, so that the alignment support leg 7 fits tightly in the alignment groove 4, occupying half of the space. This completes the one-to-one alignment of the mounting screw holes 10 at the bottom of the I-beam crane beam 2 and the top of the support plate 1. The first mounting bolt 11 is installed in the corresponding mounting screw holes 10 to complete the installation alignment of the I-beam crane beam 2 and the support plate 1.

[0034] S3: Connect one of the third mounting bolts 20 on the L-shaped connecting steel plate 3 to the mounting screw holes 10 on the I-beam crane beam 2. Fix the I-beam crane beam 2 and the L-shaped connecting steel plate 3 with the third mounting bolt 20. Install the other third mounting bolt 20 in the screw hole on the support column to fix the I-beam crane beam 2 to the support column. Fix the brake truss 22 to the I-beam crane beam 2 with bolts to complete the installation.

[0035] In use, the clamping steel plates 1402 of the support base plate 1 are placed on top of the support column on both sides. One end of the external drive device is engaged in the connecting groove of the fixing button at one end of the bidirectional threaded rod 1401, driving the bidirectional threaded rod 1401 to rotate rapidly. The rotation of the bidirectional threaded rod 1401 causes the two moving bars 1403 to move closer together. The two moving bars 1403 then drive the two clamping steel plates 1402 closer together until the clamping steel plates 1402 are clamped on both sides of the support column. After the two clamping steel plates 1402 are clamped on the outside of the support column under the rotation of the bidirectional threaded rod 1401, the alignment groove 4 is kept in the middle position at the top of the support column, preventing the alignment groove 4 from shifting and causing the bottom support of the I-beam crane beam 2 to be outside the support column, resulting in insufficient support strength. After all the support base plates 1 are installed, the I-beam crane beam 2 is lifted using external hoisting equipment, and the alignment support legs 7 at the bottom of the I-beam crane beam 2 are placed on top of the two adjacent alignment grooves 4 for alignment. The shape of the groove 4 allows the alignment support leg 7 to slide naturally into the alignment groove 4 under its own weight. Then, the alignment support leg 7 is attracted by the positive magnet 6 opposite to the negative magnet 9 installed on the alignment support leg 7, so that the alignment support leg 7 fits tightly in the alignment groove 4 and occupies half of the space. At this time, the mounting screw holes 10 at the bottom of the I-beam crane beam 2 and the top of the support base plate 1 are in one-to-one correspondence. The first mounting bolt 11 is installed in the corresponding mounting screw hole 10 to complete the installation alignment of the I-beam crane beam 2 and the support base plate 1. The third mounting bolt 20 on the L-shaped connecting steel plate 3 is aligned with the third mounting screw hole 10 on the I-beam crane beam 2. The I-beam crane beam 2 and the L-shaped connecting steel plate 3 are fixed by the third mounting bolt 20. The other third mounting bolt 20 is installed into the screw hole on the support column to securely install the I-beam crane beam 2 on the support column. The brake truss 22 is installed by several small bolts and small screw holes at the top of the I-beam crane beam 2.

[0036] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
