Please refer to Figures 1-9. The present invention provides a technical solution for the installation and hoisting equipment of a steel structure in a light steel building:
A steel structure installation and lifting equipment for light steel buildings, including a horizontal hanger, which includes a horizontal plate 1, a lifting ear 2 placed above the horizontal plate 1, and a rope 3 connected to the lifting ear 2; A guide column is vertically inserted in the middle of horizontal plate 1; Two sets of symmetrical hinged seats are fixed along the length direction below the horizontal plate 1, each consisting of two hinged 593854 ears 4 that are coaxial along the width direction of the horizontal plate 1. Each set of hinged seats is hinged with a clamping claw 5, which is clamped by the left and right clamping claws 5 and pressed downwards by the guide column to fix the steel structure component 6; A clamping device is installed at the connection between clamp claw 5 and hinge ear 4, and when clamp claw 5 rotates outward, it is clamped by the clamping device;
The guide column is connected to the clamping device through rope 7, and the upward movement of the guide column is released from the clamping claw 5 through rope 7.
The horizontal plate 1 is fixed with four lifting lugs 2 distributed in a rectangular array, and each lifting lug 2 is fixed with a rope 3. The upper ends of multiple ropes 3 are gathered together and connected to the crane.
The horizontal plate 1 is provided with a vertical large through-hole 9 in the middle, and the guide column is composed of an intermediate rod 10 placed in the through-hole and a disc 11 placed at both ends of the intermediate rod 10. The diameter of the disc 11 at both ends of the intermediate rod 10 is larger than that of the intermediate rod 10, and the two discs 11 are respectively placed on the upper and lower sides of the horizontal plate 1. There is a first spring 12 sleeved on the intermediate rod 10 between the lower circular disc 11 and the horizontal plate 1.
The lower end face of the horizontal plate 1 is equipped with a left and right direction sliding groove 13, the upper end of the hinge ear 4 is fixed with a sliding block 14, and the sliding block 14 is placed inside the sliding groove 13 to achieve left and right movement of the hinge ear 4; There are fastening bolts between slide 14 and slide 13, which are tightened to fix the slide 14 relative to the slide 13.
The clamping claw 5 is composed of an L-shaped rod 15 and an articulated shaft 16. The articulated shaft 16 is fixed with two L-shaped rods 15 that are symmetrical in front and rear. The two ends of the articulated shaft 16 are inserted into the two coaxial articulated ears 4, and there is a torsion spring between the articulated shaft 16 and the articulated ear 4. The torsion spring causes the clamping claw 5 to rotate towards the middle; The end near the middle of the hinge ear 4 is provided with a through groove 17 that is connected to the inner edge of the hinge ear 4. A pin shaft 18 is inserted into the through groove 17, and one end of the pin shaft 18 placed on the outer side of the through groove 17 is fixed with a fixed block 19. A second spring 20 is arranged between the fixed block 19 and the hinge ear 4 The hinge shaft 16 is provided with a groove 21 corresponding to the through groove 17. When the hinge shaft 16 rotates to fully conneft,503854 the groove 21 with the through groove 17, the pin shaft 18 enters the groove 21 under the action of the second spring 20 to fix the hinge shaft 16 with the hinge ear 4 and clamp the gripper 5 tightly; The locking device is composed of pin 18, fixed block 19, second spring 20, groove 21, and through groove 17; There are multiple vertical small through- holes 22 on the horizontal plate 1. One end of the rope 7 is fixed on the pin shaft 18 and placed on the outer end of the through-hole 17. The other end of the rope 7 passes through the small through-hole 22 and is connected to the upper end of the guide column. working principle:
In the initial state, the two clamping jaws 5 rotate outward, and the distribution shaft 18 enters the groove 21 under the action of the second spring 20 to fix the hinge shaft 16 and the hinge ear 4, locking the clamping jaws 5. The distance between the two clamping jaws 5 is greater than the length of the steel structure component 6 to be clamped. By moving the slider 14 left and right, the slider 14 is placed inside the slide 13 to slide, achieving the left and right movement of the hinge ear 4. Adjust the distance between the two clamping jaws 5, and then tighten the fastening bolts to fix the slider 14 relative to the slide 13.
During lifting, the suspension frame is lifted by a crane or crane to achieve the lifting and lowering of the suspension frame. It is placed above the steel structure component 6 to be lifted, and the suspension frame is moved downwards to make the disc 11 at the lower end of the guide column contact the upper end face of the steel structure component 6. Then, the suspension frame is further moved downwards to compress the first spring 12, causing the guide column to move upwards relative to the horizontal plate 1 and the clamping claw 5. The pin shaft 18 is pulled by the rope 7 to detach from the groove 21, before the clamping claw 5 does not contact the steel structure component 6,
Release the clamping claw 5 from its stuck state, and under the action of the torsion spring, rotate the clamping claw 5 towards the middle to clamp the steel structural component 6; Although the weight of the steel structure component 6 is not large each time it is lifted, in order to ensure the safety of lifting, the present invention designs the clamp 5 as an L-shape, and the clamp 5 can move left and right. Before lifting, the position of the clamp 5 is adjusted, which can achieve that when the clamp 5 clamps the steel structure component 6, the lower end of the clamp 5 is placed below the steel structure component 6 and almost parallel, increasing the vertical support for the steel structure component 6, Prevent the joint action of excessive weight and insufficient vertical supPPQts03854 force of steel structure component 6 from causing it to slip.
Then move the hanger upwards, and the first spring 12 returns to push the guide column downwards relative to the horizontal plate 1. Under the combined action of the clamping jaws 5 and the downward pressure of the guide column, fix the steel structure component 6 firmly.
When moving to the placement position, move the hanger downwards. After the steel structure component 6 is moved to the lowest end, continue to move the hanger downwards, so that the upper end of the guide column is away from the hinge shaft 16 and the pin shaft 18 is pulled by the rope 7. Under the reaction force of the steel structure component 6, further rotate the clamp claw 5 outward, move the hanger upwards, and make the clamp claw 5 detach from the steel structure component 6. The clamp claw 5 rotates in the middle under the action of the torsion spring, while the guide column moves downwards, Reset the pin shaft 18 under the action of the second spring 20. When the groove 21 rotates to fully connect with the through groove 17, the pin shaft 18 enters the groove 21 and clamps the gripper 5 tightly. The gripper 5 returns to its initial state, and the next lifting can proceed.
The above is only a preferred specific implementation of the present invention, but the scope of protection of the present invention is not limited to this. Technicians familiar with the technical field should be covered by the scope of protection of the present invention by equivalent replacement or modification based on the technical solution and inventive concept of the present invention within the scope of disclosure.
