Description

Technical Field

[0001] The utility model belongs to the technical field of section steel hoisting, and in particular relates to a section steel hoisting device. Background Art

[0002] Steel is a common metal material with a specific cross-sectional shape. It is usually produced by rolling or extrusion to form cross-sections of different shapes, including I-beams, H-beams, angle steels, channel steels, etc. These steels of different shapes are widely used in construction, bridges, machinery manufacturing, shipbuilding and other fields.

[0003] During use of the existing steel section lifting device, one end of the clamping frame is connected to the lifting equipment by a steel wire rope, and then the clamping frame is installed on both sides of the steel section in a staggered manner to facilitate the lifting of the steel section by the lifting equipment. During the lifting process, manual installation can easily make the distances between the two sets of clamping frames and the central axis of the steel section different, which will cause the steel section to be tilted during lifting, posing a safety hazard. Utility Model Content

[0004] The utility model aims to provide a steel section hoisting device.

[0005] The utility model adopts the following technical solution to solve the technical problem: a steel section lifting device comprises a casing, an adjusting mechanism is installed in the casing, a clamping mechanism is installed on the outer side of the adjusting mechanism, the adjusting mechanism is provided with a support seat, a threaded bidirectional lead screw is provided in the middle of the support seat, and guide rods with sliding connection are provided on both sides of the support seat; the clamping mechanism is provided with a frame, a slide groove is provided on the frame, and an adjusting lead screw is installed in the slide groove.

[0006] Specifically, a bracket is provided in the slide groove, the bracket is provided with a fixing plate, an adjusting screw rod threadedly connected to the fixing plate passes through the fixing plate, a clamping plate is provided at the bottom of the adjusting screw rod, and the clamping plate is connected to the adjusting screw rod through a bearing.

[0007] Specifically, one end of the bidirectional lead screw extends to the outside of the housing, and a hand wheel is fixed to the end of one end of the bidirectional lead screw.

[0008] Specifically, a mounting seat is symmetrically fixed on the top of the housing, and a lifting ring is threadedly connected to the mounting seat.

[0009] Specifically, guide grooves are symmetrically provided on both sides of the casing, and the support seat is connected to the casing through the guide grooves.

[0010] The utility model has the following beneficial effects: by arranging a casing, a handwheel and an adjusting mechanism, the clamping mechanism can be fixed on the adjusting mechanism. When hoisting the steel section, the casing is placed on the central axis of the steel section, and then the staff uses the handwheel to rotate the bidirectional screw in the adjusting mechanism. The bidirectional screw drives the two groups of support seats to move in opposite directions along the guide rod, thereby adjusting the spacing between the clamping mechanisms, avoiding different spacings between the clamping mechanisms and the central axis of the steel section, preventing the steel section from tilting during hoisting, and thus avoiding safety hazards.

Guide rods 402 are symmetrically arranged on both sides of the bidirectional screw 401, and the guide rods 402 can guide the support seat 403. The support seat 403 is provided with a bidirectional screw 401 and a guide rod 402. The support seat 403 can fix the clamping mechanism 5. There are two groups of support seats 403. The support seat 403 is threadedly connected to the bidirectional screw 401, and the support seat 403 is slidably connected to the guide rod 402.

[0017] The clamping mechanisms 5 are installed on the support base 403 , and the number of the clamping mechanisms 5 is twice that of the support base 403 , so that the support base 403 can drive multiple groups of clamping mechanisms 5 to move synchronously.

[0018] The clamping mechanism 5 includes a frame 501, which is fixedly connected to the support seat 403, and the end of the frame 501 near the support seat 403 is a triangular structure, which can ensure the supporting force of the frame 501 during use. The slide groove 502 is formed on the frame 501, and the bracket 503 is connected to the frame 501 through the slide groove 502. The bracket 503 is an L-shaped structure, which is convenient for the bracket 503 to move along the frame 501 through the slide groove 502 to adjust the position, thereby meeting the use requirements of different types of steel sections.

[0019] The fixed plate 504 is installed on the bracket 503, and the adjusting screw 505 is threadedly connected to the bracket 503. The bottom end of the adjusting screw 505 is connected to the bearing of the clamping plate 506. The adjusting screw 505 can be supported by the fixed plate 504.

The device is moved above the steel section through the lifting equipment. At this time, the casing 1 is placed on the central axis of the steel section. After the placement is completed, the staff uses the hand wheel 6 to rotate the bidirectional screw 401 in the adjustment mechanism 4, and the bidirectional screw 401 drives the two sets of support seats 403 to move in opposite directions along the guide rod 402, so as to adjust the spacing between the clamping mechanisms 5 to avoid different spacings between the clamping mechanisms 5 and the central axis of the steel section, and prevent the steel section from tilting during lifting, thereby avoiding safety hazards.
