[0001] The utility model relates to the technical field of tower lifting equipment, in particular to a quick-installation attachment crossbeam. Background Art

[0002] Existing power plant construction projects mostly use large tower cranes above 2000t·m for construction. The widespread use of large tower cranes has greatly improved the efficiency of hoisting operations. For the convenience of construction, tower cranes are usually placed next to the steel structure of the power plant. The total height of the tower crane is between 100m and 200m. The attachment device usually uses 2 to 3 steel columns. The beams are set between the columns and the columns are connected with hoops. The attachment ears are installed on the beams, so as to eliminate the bending moment of the columns and avoid the bending moment of the columns.

[0003] When installing traditional beams, the beams, lugs and clamps are usually assembled and welded on the ground after on-site measurement, and then welded after hoisting. This installation method affects the progress of the project, and high-altitude welding is difficult, and the welding accuracy and welding strength are difficult to meet the requirements. The attached beams are expensive and difficult to reuse in the welded form, resulting in a waste of resources.

[0014] Preferably, the plurality of hoop ring beams and the plurality of ear seats are located on both sides of the attachment beam joint section.

[0015] Beneficial effects of the utility model:

[0016] The utility model detachably connects the hoop ring beam and the attachment cross beam joint section through the second bolt group, thereby improving the installation accuracy of the hoop ring beam, detachably connects the attachment cross beam joint section and the attachment cross beam extension section through the first bolt group, and detachably connects the attachment cross beam joint section and the ear seat through the third bolt group, thereby making the attachment cross beam joint section and the attachment cross beam extension section recyclable, and avoiding the reduction of installation accuracy due to high-altitude welding.

[0021] The following is a further description of the method of use of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 3 As shown, a quick-install attachment beam includes a clamp lock beam 1 for fastening to a column, and also includes:

[0023] Two hoop ring beams 2 are respectively connected to opposite sides of the hoop lock beam 1;

[0024] Two attachment cross beam joint sections 3 are respectively detachably connected to the corresponding hoop ring beam 2;

[0025] A plurality of attachment beam extension sections 4 are detachably connected between two attachment beam joint sections 3, and the plurality of attachment beam extension sections 4 are connected end to end, and the number of the plurality of attachment beam extension sections 4 matches the set length of the attachment beam.

[0026] The entire set of attachment beams is assembled by bolts, and the length can be freely adjusted as needed. It has high recycling efficiency and will not cause waste of resources.

[0027] The steel plates are welded on the upper and lower parts of the main limbs of the crossbeam, and the bolt holes are reserved in the steel plates. The hoop is divided into three parts that surround the column, which are symmetrical on the left and right, and are equipped with a bottom plate with long strip bolt holes to facilitate the connection with the crossbeam.

[0028] The main limbs of the attached beams are in the form of multi-section flanges. After determining the stress of the beams according to the results of mechanical calculations, appropriate main limbs of the beams are selected, and according to the actual length of the beams, the multiple attachments of this project or the different attachment beam lengths of multiple projects are comprehensively considered, and the beams are reasonably segmented, and high-strength bolts are used to splice the multiple sections of the beams.

[0029] Maximize the recycling rate of beams and greatly reduce labor and material costs.

[0030] The attachment crossbeam connecting section 3 is connected to the attachment crossbeam extension section 4 via a first bolt group 6 .

[0031] The cross beam joint section is provided with a plurality of detachably connected ear seats 5 for strengthening the fixation of the cross beam joint section.

[0032] A first crossbeam bottom plate 31 is provided between the attachment crossbeam joint section 3 and the hoop ring beam 2 , and the attachment crossbeam joint section 3 is connected to the hoop ring beam 2 through a second bolt group 7 passing through the first crossbeam bottom plate 31 .

[0033] A second crossbeam bottom plate 32 is provided between the attachment crossbeam joint section 3 and the ear seat 5 , and the attachment crossbeam joint section 3 is connected to the ear seat 5 through a third bolt group 8 passing through the second crossbeam bottom plate 32 .

[0034] The efficient bolt connection method and fewer subdivided modules greatly improve the installation efficiency; the main limbs of the attached beam adopt a multi-section splicing form, which increases the recycling rate of the attached beam.

[0035] A combination of wedges and blocking plates is used opposite the beam to firmly fasten the beam, hoop and column. Ear seat 5 is reserved with a long strip.

[0036] The plurality of hoop ring beams 2 and the plurality of ear seats 5 are located on both sides of the attachment beam joint section 3 .

[0037] Hang the attachment beam and clamp to the attachment column, adjust the attachment height, tighten the beam, clamp and column with bolts first and then with wedges. If necessary, design an anti-skid device between the beam and the column to prevent slipping due to frequent operations resulting in gaps between the column and the beam.

[0038] Installation process: First, workers install multiple second beam bottom plates 32 at the bottom of the attached beam joint section 3, then install multiple ear seats 5 on the second beam bottom plates 32, and fix the ear seats 5 and the second beam bottom plates 32 to the bottom of the beam joint section through the third bolt group 8; install multiple first beam bottom plates 31 on the top of the attached beam joint section 3, then install the hoop ring beam 2 on the first beam bottom plates 31, and fix the hoop ring beam 2 and the first beam bottom plates 31 to the top of the beam joint section through the second bolt group 7; then, according to actual length requirements, multiple attached beam extension sections 4 will be installed between the two attached beam joint sections 3 through the first bolt group 6. After the installation is completed, the hoop lock beam 1 is welded to the hoop ring beam 2 to complete the on-site assembly.

[0039] Then, the attachment beam and clamp are hoisted to the attachment column. After adjusting the attachment height, the beam, clamp and column are first tightened with bolts and then with wedges. If necessary, an anti-skid device should be designed between the beam and the column to prevent slipping due to gaps between the column and the beam caused by frequent operations.
