Description

Technical Field

[0001] This utility model relates to the field of steel structure hoisting technology, specifically to an auxiliary tool for hoisting ultra-heavy steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields.

[0003] When using a crane to lift steel structures, the existing hoisting auxiliary structures are not very effective at securing some ultra-long steel structures, which can easily lead to dangerous phenomena such as tilting during hoisting, posing a great safety hazard. Therefore, they have certain limitations.

[0004] Therefore, it is necessary to design an auxiliary tool for hoisting ultra-heavy steel structures to improve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs an auxiliary tool for hoisting heavy steel structures. This hoisting auxiliary tool aims to solve the technical problem that existing technologies make it inconvenient to fix steel structure profiles of different lengths, which can easily lead to tilting during hoisting and affect construction safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lifting auxiliary tool for heavy steel structures includes a lifting frame. A guide slide rod is fixedly connected to the bottom left side of the lifting frame, and a bidirectional screw is rotatably connected to the bottom right side of the lifting frame. A motor is installed at one end of the bidirectional screw on the outside of the lifting frame, and the output end of the bidirectional screw is fixedly connected to the output end of the motor.

The clamping frames are sleeved on both sides of the lifting frame through the hanging ears. A reinforcing rib is fixedly connected at the connection between the hanging ears and the clamping frames. A directional pulley is rotatably connected to the bottom of the hanging ears at a position corresponding to the directional slide groove. The hanging ears are slidably connected to the directional slide groove through the directional pulley.

[0010] Preferably, the clamping frame has a sliding hole at the position corresponding to the guide slide rod, and the clamping frame is slidably connected to the guide slide rod through the sliding hole. The clamping frame has a threaded adjustment hole at the position corresponding to the bidirectional screw, and the clamping frame is threadedly connected to the bidirectional screw through the threaded adjustment hole.

[0011] Preferably, a bidirectional screw is rotatably connected to the top of the clamping frame, and a rotating handle is fixedly connected to one end of the bidirectional screw on the outside of the clamping frame. A pair of guide grooves are provided on both sides of the top of the clamping frame located on the bidirectional screw, and a set of clamping components is slidably connected to the bottom of the clamping frame.

[0012] Preferably, the clamping member has a threaded adjustment hole two at a position corresponding to the bidirectional screw two, and the clamping member is threadedly connected to the bidirectional screw two through the threaded adjustment hole two.

[0013] Preferably, a set of limiting sleeves is fixedly connected to the bottom of both sets of clamping frames on the side furthest from each other, and a material support sleeve is fixedly connected to the bottom of both sets of clamping frames on the side furthest from the limiting sleeves. A pair of anti-slip pads are fixedly connected to the bottom of both the limiting sleeves and the material support sleeves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The motor drives the bidirectional screw to rotate, so that the two sets of clamping frames are connected to the bidirectional screw through the threaded adjustment hole to adjust the spacing, which facilitates the clamping of steel structure profiles of different lengths and assists in hoisting.

[0016] 2. The limiting sleeve limits both ends of the steel structure profile to prevent it from slipping out of the clamping frame during hoisting and causing construction accidents.

[0023] Example:

[0024] This utility model provides an auxiliary tool for hoisting heavy steel structures. This hoisting auxiliary tool aims to solve the technical problem that it is not convenient to fix steel structure profiles of different lengths under the existing technology, which makes it easy to tilt during hoisting and affect the construction safety.

[0025] Please see Figures 1-4 This embodiment provides an auxiliary tool for hoisting heavy steel structures, including a hoisting frame 1. A guide slide rod 101 is fixedly connected to the bottom left side of the hoisting frame 1, and a bidirectional screw rod 102 is rotatably connected to the bottom right side of the hoisting frame 1. A motor 1021 is installed at one end of the bidirectional screw rod 102 on the outside of the hoisting frame 1. One end of the bidirectional screw rod 102 is fixedly connected to the output end of the motor 1021. A hoisting lug 103 is fixedly connected to the top center of the hoisting frame 1. A reinforcing rib 1031 is fixedly connected at the connection between the hoisting lug 103 and the hoisting frame 1. The reinforcing rib 1031 enhances the connection strength between the hoisting lug 103 and the hoisting frame 1. A set of directional slide grooves 104 are provided on both sides of the hoisting lug 103 at the top of the hoisting frame 1.

[0026] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3Two sets of clamping frames 2 are slidably connected to the bottom of the hoisting frame 1. Hanging ears 201 are fixedly connected to the top of the two sets of clamping frames 2 on opposite sides. The clamping frames 2 are fitted onto both sides of the hoisting frame 1 via the hanging ears 201. A reinforcing rib 2011 is fixedly connected to the connection between the hanging ears 201 and the clamping frames 2, enhancing the connection strength. A directional pulley 2012 is rotatably connected to the bottom of the hanging ears 201 at a position corresponding to the directional groove 104. The hanging ears 201 are slidably connected to the directional groove 104 via the directional pulley 2012, improving... The clamping frame 2 has a smooth spacing adjustment mechanism. A sliding hole 202 is provided at the position corresponding to the guide slide rod 101. The clamping frame 2 is slidably connected to the guide slide rod 101 through the sliding hole 202, which improves the stability of the clamping frame 2 spacing adjustment. A threaded adjustment hole 203 is provided at the position corresponding to the bidirectional screw 102. The motor 1021 drives the bidirectional screw 102 to rotate, so that the two sets of clamping frames 2 are threadedly connected to the bidirectional screw 102 through the threaded adjustment hole 203 for spacing adjustment. This facilitates the clamping of steel structure profiles of different lengths and assists in hoisting.

[0027] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 The top of the clamping frame 2 is rotatably connected to a double-acting screw 204. One end of the double-acting screw 204 is fixedly connected to a handle 2041 on the outside of the clamping frame 2. A pair of guide grooves 205 are provided on both sides of the double-acting screw 204 at the top of the clamping frame 2. A set of clamping parts 206 are slidably connected to the bottom of the clamping frame 2. The clamping parts 206 are provided with threaded adjustment holes 2061 at the corresponding positions of the double-acting screw 204. The handle 2041 drives the double-acting screw 204 to rotate, so that the two sets of clamping parts 206 are threadedly connected to the double-acting screw 204 through the threaded adjustment holes 2061 to adjust the spacing, clamping and positioning the two sides of the steel structure profile, and improving the stability of the steel structure profile hoisting.

[0028] In this embodiment, please refer to Figure 2 and Figure 3 Each of the two sets of clamping frames 2 has a set of limiting sleeves 207 fixedly connected to its bottom and the side furthest from each other. The limiting sleeves 207 limit the two ends of the steel structure profile to prevent the steel structure profile from sliding out of the clamping frame 2 during hoisting and causing construction accidents. Each of the two sets of clamping frames 2 has a material support sleeve 208 fixedly connected to its bottom and the side furthest from the limiting sleeve 207. Each of the limiting sleeve 207 and the material support sleeve 208 has a pair of anti-slip pads 209 fixedly connected to its bottom. The anti-slip pads 209 provide support for the bottom of the clamping frame 2 and improve the stability of the clamping frame 2 when placed on the ground.

[0029] In addition, it should be noted that the motor 1021 is all existing technology, and its internal working principle and operation process will not be described in detail here.

[0030] The working process of this utility model is as follows: First, the hoisting frame 1 is connected to the crane through the hoisting lug 103. The motor 1021 drives the bidirectional screw 102 to rotate, so that the two sets of clamping frames 2 are threadedly connected to the bidirectional screw 102 through the threaded adjustment hole 203. The spacing is adjusted according to the length of the steel structure profile, which facilitates the clamping of steel structure profiles of different lengths and assists in hoisting. The hanging lug 201 is slidably connected to the directional slide groove 104 through the directional pulley 2012, which improves the smoothness of the spacing adjustment of the clamping frame 2. The rotating handle 2041 drives the bidirectional screw 204 to rotate, so that the two sets of clamping parts 206 are threadedly connected to the bidirectional screw 204 through the threaded adjustment hole 2061, which adjusts the spacing and clamps and positions the two sides of the steel structure profile, improving the stability of the steel structure hoisting. The limiting sleeve 207 limits the two ends of the steel structure profile to prevent the steel structure profile from sliding out of the clamping frame 2 during hoisting and causing construction accidents.

[0031] The entire operation process is simple and convenient. Compared with existing hoisting auxiliary tools, this utility model is designed to be adaptable to the hoisting of steel structure profiles of different lengths, thereby improving the stability of steel structure profile hoisting and enhancing overall practicality.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
