Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting, and particularly relates to an auxiliary tooling for steel structure hoisting construction. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. Because of its simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. When a steel structure is put into use, it needs to be hoisted, so special hoisting construction auxiliary tooling is required. The auxiliary tooling for steel structure hoisting construction refers to various tools and equipment specially designed and used during the installation process of steel structures, which are used to assist in the lifting, positioning, fixing and connection of steel components. The use of auxiliary tooling can improve construction efficiency, safety and accuracy, and ensure the smooth progress of the steel structure installation process.

[0003] In the Chinese utility model patent with the publication number of CN211619756U, a hoisting tooling for steel structures is disclosed. By rotating the lead screw, as the lead screw moves upward, it drives the connecting rod to pull closer two clamping rods symmetrically distributed, thereby driving the U-shaped clamping blocks to clamp the I-shaped steel structure. Then, the lifting lug is connected to the hoisting device to realize the hoisting of the I-shaped steel structure.

[0004] When this device is actually used, it is necessary to manually adjust the device to clamp and release the steel structure before and after hoisting, which is not only troublesome but also reduces the hoisting efficiency of the steel structure.

[0005] In summary, there is a need for an auxiliary tooling that can automatically clamp steel structures at present. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an auxiliary tooling for steel structure hoisting construction. With the cooperation of the gravity of the steel structure itself, when the hoisting device hoists the steel structure, it will first drive the symmetrically arranged clamping plates to approach the steel structure to clamp and limit it. When the clamping plates contact the steel structure, the whole device will be lifted, thus realizing the purpose of automatically clamping the steel structure.

[0007] The technical solution adopted by the utility model to solve the above problems is: an auxiliary tooling for steel structure hoisting construction, comprising:

[0008] A bottom plate, above which a top plate is movably connected, and a lifting lug is fixedly connected to the top of the top plate;

[0009] An automatic clamping assembly, the automatic clamping assembly includes a sliding rod fixedly connected to the top of the bottom plate, a sliding plate is arranged above the bottom plate, and the sliding plate is slidably connected with the sliding rod. A clamping plate is fixedly connected to the top of the sliding plate, and a connecting rod is hinged between the clamping plate and the top plate through a hinge member.

[0010] The bottom plate is at the bottom of the entire device. As the foundation and support part of the device, it provides a stable steel structure installation platform. The bottom plate is usually abutted against the ground or the bottom surface of steel members, and is used to bear and disperse the weight of the entire device and the temporary supporting force on the steel structure during construction.

[0011] The top plate is above the bottom plate and is connected to the bottom plate by a movable connection method. It is used to provide support for the clamping and lifting structures. A lifting lug is fixedly connected to the top of the top plate for connecting lifting equipment (such as hooks, lifting chains, etc.). The lifting lug enables the entire device to be lifted to complete the lifting and movement of steel members.

[0012] The automatic clamping assembly is located between the bottom plate and the top plate, and includes parts such as slide rods, slide plates, clamping plates, hinge parts and connecting rods, etc., for realizing the operation of automatically clamping and releasing steel members. The slide rod is fixed on the top of the bottom plate and extends vertically upward, providing a guiding and supporting structure to enable the slide plate to move along the direction of the slide rod, and the slide rod ensures that the movement of the slide plate is controlled and stable.

[0013] The slide plate is above the bottom plate and is slidably connected to the slide rod. Under the guidance of the slide rod, the slide plate can move up and down. A clamping plate is fixedly connected to the top of the slide plate. Through the movement of the slide plate, the clamping plate can approach or move away from the steel member to realize clamping or releasing.

[0014] A connecting rod is hinged between the clamping plate and the top plate through a hinge part. By hingedly connecting the clamping plate and the top plate, a structure similar to a lever is formed. When the top plate rises, the connecting rod will push the clamping plate closer to the steel member to clamp the steel member; conversely, when the top plate descends, the connecting rod will pull the clamping plate away from the steel member to release the steel member.

[0015] The clamping plate is fixed on the top of the slide plate. It directly contacts and clamps the steel member. The design of the clamping plate usually takes into account the matching with the shape and size of the steel member to ensure the firmness and safety of clamping.

[0016] The design of this auxiliary tooling for steel structure hoisting construction aims to simplify and accelerate the hoisting process of steel members through an automatic clamping mechanism. Each component works in coordination to achieve the following functions: through the sliding of the slide plate and the clamping plate and the action of the hinged connecting rod, automatic clamping of the steel member is realized. The lifting lug on the top plate is connected to the lifting equipment, enabling the entire device and the steel member to be safely lifted. The automatic clamping assembly improves the construction efficiency and reduces the complexity and error of manual operation.

[0017] A further preferred technical solution is that: a vertical rod is fixedly connected to the top of the bottom plate and is slidably connected between the vertical rod and the top plate.

[0018] A further preferred technical solution is that a limiting plate is fixedly connected to the top end of the vertical rod, and a return spring is sleeved outside the vertical rod.

[0019] A further preferred technical solution is that both ends of the return spring are fixedly connected to the limiting plate and the top plate respectively.

[0020] A further preferred technical solution is that an anti-slip pad is fixedly connected to the clamping plate.

[0021] A further preferred technical solution is that an integral connecting rod is provided between the lifting lug and the top plate.

[0022] A further preferred technical solution is that four groups of the vertical rods are arranged on the top of the bottom plate and are respectively fixed at the four corners of the top of the bottom plate.

[0023] A further preferred technical solution is that two lifting lugs are arranged on the top of the top plate and are symmetrically arranged along the center line of the top plate.

[0024] A further preferred technical solution is that four groups of the sliding rods are arranged on the top of the bottom plate, and two by two are used for slidably connecting the sliding plates.

[0025] A further preferred technical solution is that two groups of the connecting rods are hinged to a single clamping plate through hinge parts.

[0026] In summary, the present utility model has the following beneficial effects:

[0027] 1. When the lifting device hooks the lifting lug to lift the steel structure, under the sliding cooperation between the top plate and the vertical rod, the sliding cooperation between the sliding plate and the sliding rod, the hinged action between the clamping plate, the top plate and the connecting rod, and the gravity action of the steel structure itself, when the lifting device lifts the steel structure, it will first drive the symmetrically arranged clamping plates to approach the steel structure to clamp and limit it. When the clamping plate contacts the steel structure, the whole device will be lifted, thus realizing the purpose of automatically clamping the steel structure without manual operation by the operator, effectively improving the hoisting efficiency of the steel structure.

[0028] 2. The present utility model can automatically perform multi-point clamping and limiting on the whole steel structure, thereby improving the stability of the steel structure during hoisting and further increasing the safety during construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment:

[0036] Please refer to Figures 1-3 , an auxiliary tool for the hoisting construction of a steel structure in this embodiment, includes:

[0037] A bottom plate 1, a top plate 2 is movably connected above the bottom plate 1, lifting lugs 3 are symmetrically and fixedly connected to the top of the top plate 2, and the lifting lugs 3 and the top plate 2 are integrally structured. The size of the bottom plate 1 is the same as that of the top plate 2;

[0038] An automatic clamping assembly, the automatic clamping assembly includes four groups of sliding rods 101 symmetrically and fixedly connected to the top of the bottom plate 1. Four groups of sliding plates 102 are symmetrically arranged above the bottom plate 1 and the sliding plates 102 are slidably connected to two groups of sliding rods 101 on the same side. A clamping plate 103 is fixedly connected to the top of the sliding plate 102. Connecting rods 104 are symmetrically hinged between the clamping plate 103 and the top plate 2 through hinge parts. Vertical rods 105 are vertically and fixedly connected to the four corners of the top of the bottom plate 1 and the vertical rods 105 are slidably connected to the top plate 2. A limiting plate 106 is fixedly connected to the top end of the vertical rod 105. A return spring 107 is sleeved outside the vertical rod 105, and the two ends of the return spring 107 are respectively fixedly connected to the limiting plate 106 and the top plate 2, which is convenient for the device to automatically reset when lifting the steel structure. The clamping plate 103 is of an L-shaped structure design, which can not only support the steel structure, but also clamp and limit it.

[0039] In the embodiment of the present application, the implementation principle of an auxiliary tooling for steel structure hoisting construction is as follows: First, place the steel structure horizontally on the clamping plate 103, then connect the hoisting device to the lifting lug 3 and hoist it. Under the sliding fit between the top plate 2 and the vertical rod 105, the sliding fit between the sliding plate 102 and the sliding rod 101, the hinged action between the clamping plate 103 and the top plate 2 and the connecting rod 104, and the gravity of the steel structure itself, when the hoisting device hoists the steel structure, it will first drive the symmetrically arranged clamping plates 103 to approach the steel structure to clamp and limit it. When the clamping plate 103 contacts the steel structure, the whole device will be lifted, thus realizing the purpose of automatically clamping the steel structure without manual operation by the operator, effectively improving the hoisting efficiency of the steel structure. Finally, after the steel structure is hoisted to the designated area, lift the steel structure and transport it away. At this time, under the resilience of the return spring 107, the clamping plate 103 will automatically reset.

[0040] Further improvement lies in that: an anti-slip pad 108 is fixedly connected to the clamping plate 103, which can increase the friction between the clamping plate 103 and the steel structure and prevent it from slipping during the hoisting process.

[0041] In addition, as much as possible, the same or similar element symbols are used in the drawings and the description to refer to the same or similar parts or steps.
