Technical Field

[0001] The utility model relates to the field of scaffold load detection, in particular to a scaffold crossbeam load detection fixing tool. Background Art

[0002] Scaffolding is a temporary construction facility commonly used in construction, decoration and various projects. It provides a safe working platform for construction workers. As an important part of the scaffolding structure, the scaffolding beam bears various loads generated during the construction process. It needs to be fixed during load testing to facilitate subsequent testing.

[0004] The above-mentioned fixing device has the advantage of being able to ensure the fixing effect of the beam and at the same time avoid the occurrence of local deformation of the beam due to excessive clamping force. However, when the scaffolding beams are placed and fixed, beams of different lengths require the use of corresponding tooling, which is not convenient for the rapid adjustment of the fixed spacing and the fixing of the beams. When the beams are taken out after the inspection is completed, friction is easily generated on the surface of the beams, which is inconvenient for the removal of the beams and the positioning of the two ends.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] Combine Figure 1-Figure 3 A scaffolding beam load detection fixing tool comprises a base plate 1, a fixing seat 2 and a fixing plate 3 are fixedly installed on the top of the base plate 1 near the rear end and the front end respectively, and a positioning mechanism 4 is installed between the fixing seat 2 and the fixing plate 3.

[0024] See Figure 2 , it is further obtained that the positioning mechanism 4 includes a slide 6 and three slide rods 7, the three slide rods 7 are fixedly installed between the fixed seat 2 and the fixed plate 3, the slide 6 is movably installed on the outside of the three slide rods 7, fixed blocks 8 are fixedly installed on both sides of the slide 6, and an adjusting rod 9 is movably installed inside the fixed block 8, and a pressure plate 10 is fixedly installed on the bottom of the adjusting rod 9. Friction grooves 11 are provided on both sides of the top of the bottom plate 1, and a support plate 12 is fixedly installed on the top of the slide 6 and the fixed seat 2. A pneumatic cylinder 13 is installed on the top of the support plate 12, and a pressure plate 14 is installed on the bottom end of the telescopic rod of the pneumatic cylinder 13. Guide rods 15 are fixedly installed on both sides of the top of the pressure plate 14, and two limit plates 16 are fixedly installed on one side of the support plate 12, and a roller 17 is movably installed on the bottom of the limit plate 16.

[0025] The slide 6 is located outside the three slide rods 7 and is slidable back and forth. The fixed seat 2 and the slide 6 are symmetrical to each other. The distance between the fixed seat 2 and the slide 6 is adjusted by sliding the slide 6.

[0026] The adjusting rod 9 is threadedly connected to the interior of the fixing block 8 . One side of the support plate 12 is open, and the crossbeam is taken in and put out through the opening on the side of the support plate 12 .

[0027] The guide rod 15 passes through the top of the support plate 12 and is slidably connected. The roller 17 is located at the bottom of the limit plate 16 and is movably rotated. The roller 17 contacts the top of the beam, and the rotation of the roller 17 reduces friction on the beam.

[0028] Specifically, the distance between the sliding slide 6 and the fixed seat 2 is adjusted to adapt to beams of different lengths. The pressure plate 10 is driven by the adjusting rod 9 to contact the friction groove 11 to support and fix the slide 6. The beam is placed between the fixed seat 2 and the slide 6 from the opening on one side of the support plate 12. The pressure plate 14 is driven down by the pneumatic cylinder 13 to press and fix the two ends of the beam.

[0029] Example 2

[0030] See Figure 3 On the basis of Example 1, it is further obtained that a lifting assembly 5 is installed inside the sliding seat 6 and the fixed seat 2. The lifting assembly 5 includes two lifting rods 18 and two contraction grooves 19. The lifting rods 18 are movably installed in the contraction grooves 19. The outside of the lifting rods 18 is sleeved with a spring 20. A cross bar 21 is fixedly installed between the top ends of the two lifting rods 18.

[0031] The contraction groove 19 is respectively opened inside the fixed seat 2 and the slide seat 6. The lifting rod 18 is located in the contraction groove 19 and is slidable up and down. The lifting rod 18 slides up and down under the action of the spring 20, so that the cross bar 21 is always stuck in the hook of the beam.

[0032] Ventilation holes are provided at the upper and lower ends of the shrinkage groove 19 . The diameter of the cross bar 21 is larger than the diameter of the lifting rod 18 , and the hook of the cross beam is hung through the cross bar 21 .

[0033] Specifically, by pressing the cross bar 21 downward, the lifting rod 18 slides downward and shrinks into the shrinkage groove 19, and then the hook of the beam is hung on the cross bar 21. The cross bar 21 is lifted upward under the action of the spring 20, and drives the cross bar to rise, while keeping the hook of the beam always hung on the cross bar 21.

[0034] In actual operation, the crossbeam is fixed between the fixed seat 2 and the sliding seat 6, and the hook of the crossbeam is hooked on the crossbar 21 to facilitate the load detection of the crossbeam;

[0035] When taking, placing, and fixing, push the slide 6 to a position that matches the length of the beam, rotate the two adjusting rods 9 respectively, and drive the pressure plate 10 to slide downward under the action of the thread to contact the friction groove 11, further supporting and fixing the slide 6. Place the beam between the fixed seat 2 and the top of the slide 6 through the opening on one side of the support plate 12. By activating the two pneumatic cylinders 13, the two pressure plates 14 are lowered to press and fix the two ends of the beam, so as to facilitate the subsequent detection of the beam load;

[0036] During the lifting and fixing process, when the crossbeam is placed between the fixed seat 2 and the slide 6, the hooks at both ends of the crossbeam are respectively hung on the two cross bars 21 to facilitate the positioning of the crossbeam. The cross bar 21 is lifted upward under the action of the spring 20, and drives the crossbeam to rise and separate from the fixed seat 2 and the slide 6, and contact with the roller 17. Through the rotation of the roller 17, the crossbeam is easily removed and the friction is reduced. The crossbeam is pressed downward by the pressure plate 14, so that the lifting rod 18 is retracted into the retraction groove 19.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
