Description

Technical Field

[0001] The utility model belongs to the technical field of air duct construction, and particularly relates to a hoisting device for an air duct lined in an air well. Background Art

[0002] During the construction process, ventilation and air conditioning systems are usually connected to the end of each floor system in the form of lined air ducts in the air shaft. Lined air ducts are usually hoisted with a labor-saving device such as a hand chain hoist. Usually, the construction team will find a channel steel, angle steel, or steel pipe at the construction site as a fixed cross arm of the hand chain hoist (the cross arm is usually between the air shaft beams) because there is no suitable fixed object for the hand chain hoist.

[0003] At present, during the construction process, the duct construction team uses channel steel, angle steel, and steel pipe as cross-arm materials. These materials are only supported at both ends of the wind shaft beam without any fixing measures, which are prone to offset and displacement. In addition, due to the weight of the duct itself and the various forces applied to the duct by personnel during the hoisting process, the channel steel, angle steel, and steel pipe are prone to bending and deformation, which is extremely unfavorable for safe construction. Utility Model Content

[0004] The utility model aims to provide a hoisting device for an air duct lined in an air shaft.

[0005] The utility model is realized by the following measures: a hoisting device for an air duct lined with an air shaft, characterized in that it comprises a connecting shaft, at least three diagonal braces uniformly distributed on the connecting shaft in the circumferential direction, and a hoisting machine arranged below the connecting shaft;

[0006] The outer wall of the connecting shaft is provided with a plurality of connecting wing plates corresponding to the diagonal braces one by one, and the upper end of the diagonal brace is provided with an adjustment plate, which is rotatably arranged on the connecting wing plate, and the adjustment plate is provided with a long strip opening, and the connecting wing plate is provided with a plurality of adjustment holes matching the long strip opening, and the adjustment plate is rotated so that all the adjustment holes can correspond to the long strip opening, and a connecting piece is also included to fix the adjustment plate and the connecting wing plate through the adjustment holes and the long strip opening. The connecting wing plate is generally connected to the connecting shaft by welding, and the connecting shaft generally adopts a solid structure.

[0007] Furthermore, the connecting member is a bolt or a pin. The outer diameter of the bolt and the pin is generally larger than the inner diameter of the adjustment hole. Preferably, the outer diameter of the bolt and the pin is generally twice the inner diameter of the adjustment hole.

[0008] Furthermore, the connecting wing plate and the adjusting plate are rotatably connected by bolts and can be fixed by nuts.

[0009] Furthermore, the diagonal brace is a telescopic rod.

[0010] Furthermore, the connecting wing plates on the same horizontal plane are a group and several groups are arranged along the axis direction of the connecting shaft. Since the installation position of the diagonal brace is on the beam of the air shaft, when there are other air shafts around the air shaft, the diagonal brace sometimes cannot be fixed by simply adjusting the angle. Therefore, the connecting wing plates are arranged in several groups along the axis of the connecting shaft, and the diagonal brace can be fixed on other connecting wing plates according to actual conditions, so that the diagonal brace can be fixed on the corresponding beam.

[0011] Furthermore, the telescopic rod includes a leg sleeve and a leg sleeved in the leg sleeve, and a plurality of connecting holes are provided on the leg and the leg sleeve. The leg and the leg sleeve are fixed by bolts, and the length of the entire diagonal brace can be adjusted by controlling the extension length of the leg.

[0012] Furthermore, a bottom plate is rotatably provided at the lower end of the supporting leg, and a plurality of mounting holes are reserved on the bottom plate. The bottom plate is rotatably connected to adjust the fixed position, thereby ensuring that the bottom plate has good contact with the connection surface.

[0013] Furthermore, the hoist is a manual hoist, a lifting ring is provided below the connecting shaft, and an upper hook of the manual hoist is hung on the lifting ring.

[0014] Furthermore, a safety hook is provided between the upper hook and the lifting ring of the manual hoist, and the upper hook of the manual hoist is hung on the safety hook.

[0015] Directions:

[0016] After determining the construction position of the air duct, first fix the three diagonal braces on the connecting shaft; then adjust the length of the diagonal brace, and after the legs are extended to the appropriate length, use bolts and nuts to pass through the connection holes on the leg sleeves and legs to fix the length of each diagonal brace; then adjust the angle of the diagonal brace, and rotate the diagonal brace around the mounting bolts of the connecting wing plate and the adjustment plate. When it rotates to the appropriate position, when an adjustment hole on the connecting wing plate coincides with the long strip on the adjustment plate, tighten and fix it with bolts and nuts; fix two of the bottom plates of the device to the first and second beams of the wind shaft with expansion bolts, and fix the other bottom plate to the beam or wall on the other side of the wind shaft; at this time, the entire device has been completely fixed, screw the lifting ring into the threaded hole below the connecting shaft, and then hang the safety hook on the lifting ring, and hang the upper hook of the hand chain hoist on the safety hook. At this time, the device has the conditions for lifting the bottom air duct.

[0017] Several groups of connecting wing plates are arranged along the axis of the connecting shaft, so that when the lower connecting wing plate is connected to the diagonal brace, if there is no condition to fix the diagonal brace, the diagonal brace can be fixed on the upper connecting wing plate, and then the above working process can be repeated.

[0018] The beneficial effects of the technical solution provided by the embodiment of the utility model are: compared with the existing crossarms, the use of the present application makes the hoisting of the air duct lined in the air shaft safer, the stability of lifting heavy objects is improved, and the device is easy to carry and is suitable for inter-floor movement in multi-story buildings.
