Description

Technical Field

[0001] This application relates to the technical field of hammock supports, especially hammock shelves. Background Art

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating and hot-dip galvanization, is an effective method for metal anti-corrosion, mainly used on metal structure facilities in various industries. Hot-dip galvanizing involves lifting a rust-removed steel part, lowering it into molten zinc at around 500 °C, so that a zinc layer adheres to the surface of the steel component, thereby achieving the purpose of anti-corrosion. It is the most basic, economical, and effective method for steel material anti-corrosion.

[0003] After a zinc layer adheres to the surface of a steel component through the hot-dip galvanizing process, equipment such as a crane is usually used to lift it onto a shelf. The steel component usually cools naturally to room temperature to ensure that the zinc layer can fully solidify and tightly bond with the surface of the steel component. In this way, the galvanized layer can provide long-term anti-corrosion protection for the steel component and extend its service life.

[0004] In actual operation, workers usually manually place two crossbeams parallel to each other on the ground according to the size of the steel component to form a simple support platform, so that the steel component and the hammock can be stably placed on this simple platform for cooling. However, since the way workers manually place the crossbeams has the problem that the crossbeams may not be placed parallel due to human factors, this may cause the steel component to be placed unstably, and even lead to serious situations such as the steel component tilting and collapsing, reducing the safety of the device.

An extension slide rod 3 is slidably connected inside the extension chute 2. One end of the extension slide rod 3 is fixedly connected to a cross beam 4. A plurality of cushion blocks 5 are installed at the bottom of the cross beam 4. In the middle section of the inside of the connecting rod 1, an installation chamber 6 is provided. An extension screw rod 7 is rotatably connected inside the extension chute 2. On the inner side of the installation chamber 6, a driven bevel gear 8 fixedly connected to the extension screw rod 7 is symmetrically rotatably connected. And on one side of the inside of the installation chamber 6, a driving bevel gear 9 meshing with the driven bevel gear 8 is rotatably connected. One end of the driving bevel gear 9 passes through the connecting rod 1 and is fixedly connected to an extension handle 10.

[0037] When in use, first manually rotate the extension handle 10 to drive the driving bevel gear 9 to rotate, and make the driving bevel gear 9 engage with the driven bevel gear 8, so as to drive the two driven bevel gears 8 to rotate synchronously. At the same time, make the two driven bevel gears 8 drive the two extension screw rods 7 to form a threaded connection with the two extension slide rods 3 respectively, so as to drive the two extension slide rods 3 to move away from each other along the length direction of the extension chute 2, and make the two extension slide rods 3 push the cross beam 4 to move along the length direction of the extension chute 2, so as to facilitate the parallel placement of the two cross beams 4 along the length direction of the extension chute 2, thereby reducing the serious situation that the steel components are placed unstably or even tilted and collapsed due to the non-parallel placement of the two cross beams 4, and improving the stability and safety of the device.

[0038] Refer to Figure 1 and Figure 3 , an adjustment chute 11 is provided at the bottom of the cross beam 4. An adjustment slider 12 is slidably connected inside the adjustment chute 11.

[0049] During use, first, by rotating the driving screw rod 25, a threaded connection is formed with the driving slider 24, and the driving slider 24 is driven to move along the length direction of the driving chute 23 towards the support rod 21. At the same time, one end of the driving slider 24 pushes the transmission rod 26 around the hinge axis, and one end of the transmission rod 26 pushes the support rod 21 to rotate around the hinge axis, and one end of the support rod 21 drives the universal wheel 22 to rotate around the hinge axis until it forms a rolling contact with the ground, so that the cross beam 4 forms a rolling contact with the ground through the universal wheel 22, so that pushing the cross beam 4 can drive the universal wheel 22 to roll along the ground, thus facilitating the movement of the cross beam 4 along the ground and effectively improving the practicability of the device.

[0051] Then, by manually rotating the extension handle 10, the driving bevel gear 9 is driven to rotate, and the driving bevel gear 9 meshes with the driven bevel gear 8, so as to drive the two driven bevel gears 8 to rotate synchronously. At the same time, the two driven bevel gears 8 drive the two extension screw rods 7 to be respectively threadedly connected with the two extension slide rods 3, so as to drive the two extension slide rods 3 to move away from each other along the length direction of the extension chute 2, and the two extension slide rods 3 push the cross beam 4 to move along the length direction of the extension chute 2, so as to facilitate the parallel placement of the two cross beams 4 along the length direction of the extension chute 2. Then, push the cross beam 4 to drive the universal wheel 22 to move along the ground to the required area;

[0052] Next, according to the center of gravity deviation of the steel member, manually push the cushion block 5 to drive the adjustment slider 12 to move along the length direction of the adjustment chute 11 to a position close to the center of gravity of the steel member. Then, by manually tightening the locking nut 15, the locking nut 15 moves along the length direction of the locking screw rod 14 towards the cross beam 4, and the locking nut 15 forms a tight fit with one side of the cross beam 4 to fix the cushion block 5. Finally, by reversely rotating the driving screw rod 25, the support rod 21 is driven to drive the universal wheel 22 to disengage from the rolling contact with the ground and retract into the inside of the retraction groove 20.
