Description

Technical Field

[0001] The utility model relates to the technical field of steel structure hoisting, in particular to a steel structure hoisting edge and corner protection tool. Background Art

[0002] At present, as chemical plants become larger and larger, the use of steel structures is becoming more and more optimized, from the original on-site prefabrication of raw materials to the current arrival of prefabricated products, from single-piece installation to the current installation of pieces and frames, the advantages of steel structures in terms of ease of manufacture and installation and short construction period are becoming more and more obvious. The installation of various types of steel structures involves hoisting work. A steel structure hoisting edge protection tool with publication number CN212982218U discloses four semi-cylindrical protection sheets with arc-shaped cross sections, the port diameter of the arc-shaped cross section of each protection sheet is larger than the thickness of the flange plate of the steel structure, when in use, the four protection sheets are respectively placed on the flange plates at the four corners of the steel structure, so that the edges of each flange plate extend into the protection sheet from the port of a protection sheet, and then the steel wire rope is tied to the four protection sheets, and then the steel structure can be started to be hoisted; however, in this patent document, since the user needs to manually place the protection sheets, and the user needs to manually fix the protection sheets when the steel wire rope is tied to the four protection sheets, the operation is complicated, resulting in low work efficiency, and at the same time, during the hoisting process, the protection sheets will also wear against the steel structure, and the protection sheets are only arranged at the position in contact with the steel wire rope, resulting in the two ends of the steel structure being exposed to the outside, which is easy to collide with foreign objects, and the safety factor is poor, and the safe hoisting of the steel structure cannot be guaranteed.

[0003] There may already be technical means to solve the above problems in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0004] Purpose of the utility model: The purpose of the utility model is to provide a steel structure hoisting corner protection tool to address the deficiencies in the prior art.

[0005] Technical solution: The utility model discloses a steel structure hoisting edge protection tool, comprising a lifting lug, a T-shaped frame is installed at the lower end of the lifting lug, a supporting circular frame is installed at the lower end of the T-shaped frame, a steel structure is movably arranged at the middle part of the supporting circular frame, and an edge protection structure is installed on the T-shaped frame;

[0006] The edge protection structure includes cylinders symmetrically installed on the T-shaped frame. A motor is installed at the telescopic end of the cylinder, and a sleeve is installed at the driving end of the motor. The opening of the sleeve is aligned with the supporting square frame. A middle U-shaped support plate is installed at the middle part of the outer wall surface of the supporting square frame, and an end U-shaped support plate is installed at the middle part of the outer wall surface of the sleeve. The plane where the lower wall surface of the middle U-shaped support plate is located is the same plane as the plane where the lower wall surface of the end U-shaped support plate is located. An active guiding component is installed on the motor.

[0007] Preferably, the active guiding component includes a connecting frame, and a guiding rod is installed on the connecting frame. The guiding rod is movably inserted on the T-shaped frame.

[0008] Preferably, a middle flexible pad is installed on the inner wall surface of the supporting square frame.

[0009] Preferably, an end flexible pad is installed on the inner wall surface of the sleeve.

[0010] Preferably, an extension column is installed between the cylinder and the T-shaped frame.

[0011] Preferably, a connecting edge is provided between the sleeve and the driving end of the motor.

[0012] Beneficial effects: The steel structure body is horizontally installed on the supporting square frame. The cylinders on both sides of the T-shaped frame are controlled to extend and the motor works to make the sleeve buckle on the end of the steel structure body. The sleeves on both sides clamp the end of the steel structure body, realizing the fixation of the steel structure body, avoiding the compression of the edges and corners of the steel structure, with simple operation and high work efficiency. Through the clamping of the sleeves on both sides, it prevents the steel structure body from moving during hoisting, avoiding mutual abrasion between the steel structure body and the tools. The sleeve shields and protects the end of the steel structure body, preventing it from colliding with external objects, ensuring the safe hoisting of the steel structure. When the device is placed on the ground, the middle U-shaped support plate and the end U-shaped support plate support on the ground, expanding the distance between the steel structure body and the ground, preventing the steel structure body from being worn due to uneven ground.

Specific implementation mode

[0018] The technical solution of the present utility model will be described in detail below with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the described embodiments.

[0019] Embodiment: By those skilled in the art, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of the electrical components working successively in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no description of electrical control will be made. Please refer to Figures 1-3 , in order to solve the problems of complex operation, low work efficiency, easy wear between the steel structure and the protection sheet, the two ends of the steel structure are exposed and easy to collide with foreign objects, and poor safety factor when using the protection sheet to protect the steel structure, this technical solution is designed, and the detailed technical solution is as follows;

[0020] A steel structure hoisting edge protection tool includes a lifting lug 1, a T-shaped frame 2 is installed at the lower end of the lifting lug 1, a supporting loop frame 3 is installed at the lower end of the T-shaped frame 2, a steel structure body is movably arranged in the middle of the supporting loop frame 3, and an edge protection structure is installed on the T-shaped frame 2;

[0021] It should be noted that the lifting lug 1 is used to connect the hoisting equipment, and the supporting loop frame 3 is connected to the lifting lug 1 through the T-shaped frame 2. During use, the supporting loop frame 3 is sleeved on the middle part of the steel structure body;

[0022] Specifically, the edge protection structure includes cylinders 4 symmetrically installed on the T-shaped frame 2, a motor 5 is installed at the telescopic end of the cylinder 4, a sleeve 6 is installed at the driving end of the motor 5, the opening part of the sleeve 6 is aligned with the supporting loop frame, a middle U-shaped support plate 7 is installed at the middle part of the outer wall surface of the supporting loop frame 3, an end U-shaped support plate 8 is installed at the middle part of the outer wall surface of the sleeve 6, the plane where the lower wall surface of the middle U-shaped support plate 7 is located is the same plane as the plane where the lower wall surface of the end U-shaped support plate 8 is located, and a movable guiding component is installed on the motor 5;

[0023] It should be noted that when placing the steel structure on the support loop 3, the motor 5 drives the sleeve 6 to rotate to the upper position, so that the steel structure can be horizontally installed on the support loop 3. Subsequently, by controlling the elongation of the cylinders 4 on both sides of the T-shaped frame 2, the sleeve 6 is moved to a certain distance from the end of the steel structure. Then the motor 5 drives the sleeve 6 to rotate to align with the end of the steel structure. Subsequently, the cylinders 4 are controlled to contract, so that the sleeve 6 is buckled on the end of the steel structure. The sleeves 6 on both sides clamp the end of the steel structure, realizing the fixation of the steel structure, avoiding the pressure on the edges and corners of the steel structure, with simple operation and high work efficiency. Through the clamping of the sleeves 6 on both sides, the steel structure is prevented from moving during hoisting, and the steel structure is prevented from rubbing against tools. The sleeve 6 shields and protects the end of the steel structure, preventing it from bumping against foreign objects, ensuring the safe hoisting of the steel structure. When the device is placed on the ground, the middle U-shaped support plate 7 and the end U-shaped support plate 8 support on the ground, expanding the distance between the steel structure and the ground, preventing the steel structure from being worn due to uneven ground;

[0024] During the hoisting process, when welding or assembling the steel structure, as Figure 4 shown, first the motor 5 on the left drives the sleeve 6 to rotate, causing the sleeve 6 to flip 180 degrees. At this time, with the movement of the crane or other tools, the left end of the steel structure on this device is docked with other steel structures to achieve corresponding welding or assembly. After welding, the crane drives this device to move to the right until the steel structure is separated from this device. When the right end of the steel structure is welded or assembled with other steel structures, the motor at the right end drives the sleeve to rotate 180 degrees. After welding, the crane drives this device to move horizontally until the steel structure is separated from this device. The cylinders and motors are set to two, so that there is no need to distinguish between left and right directions during assembly or welding, making it more convenient and fast to use.

[0025] Preferably, further, the movable guiding component includes a connecting frame 9. A guiding rod 10 is installed on the connecting frame 9. The guiding rod 10 is movably inserted into the T-shaped frame 2. When the cylinders 4 expand and contract, the guiding rod 10 moves on the T-shaped frame 2 accordingly, supporting the motor 5 and protecting the telescopic ends of the cylinders 4;

[0026] Preferably, further, a middle flexible pad 11 is installed on the inner wall surface of the support loop 3 to prevent mutual wear between the steel structure and the support loop 3;

[0027] Preferably, further, an end flexible pad 12 is installed on the inner wall surface of the sleeve 6 to prevent mutual wear between the steel structure and the sleeve 6;

[0028] Preferably, further, an extension column 13 is installed between the cylinder 4 and the T-shaped frame 2;

[0029] Preferably, further, a connecting edge 14 is provided between the sleeve 6 and the driving end of the motor 5 for connecting the sleeve 6 and the driving end of the motor 5.

[0030] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation on the present invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
