Description

Technical Field

[0001] The utility model relates to the technical field of hoisting clamps, in particular to a hoisting safety fixing device. Background Art

[0002] Many common objects in engineering construction are cylindrical and need to be fixed by clamps during transportation. Larger objects need to be transported with cranes.

[0003] For example, patent CN216010411U proposes a gas cylinder transportation hoisting safety fixing device, which places the gas cylinder horizontally in a semicircular groove on the base, places a rubber ring in the rubber ring groove, and buckles the semicircular buckle cover on the base, so that the gas cylinder is completely buckled. The semicircular buckle cover and the base are fixedly connected as a whole through a quick connection structure, so that the gas cylinder is completely fixed. The rubber ring is firmly sleeved on the surface of the gas cylinder, and the utility model is stuck on the rubber ring, and there will be no relative sliding between the utility model and the gas cylinder. Since the lower surface of the base is a plane, it can be stably placed in the car, and the gas cylinder will not move during transportation, thereby preventing damage caused by collision of the gas cylinder. The two sides of the base are vertical surfaces, and multiple gas cylinders can be placed in a close proximity to each other, so that all gas cylinders can be stably placed in the car. Thereby ensuring the stability and safety of the gas cylinder during transportation.

[0004] The shortcomings of the solution are: although the gas cylinder can be clamped and fixed by the upper and lower semicircular grooves to maintain stability during transportation, when the crane is lifted and transported, the selected lifting rope is usually a chain or wire rope, the material is easy to bend, which causes the object to shake due to inertia and other problems during the lifting and transportation process, thereby affecting the stability of the object during transportation. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a lifting safety fixing device to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. After the lifting rope is buckled with the upper plate, the telescopic rods on both sides are locked with the upper plate to form a triangular connection structure, thereby maintaining stability during the lifting and transportation process. The hard connection of the telescopic rods on both sides prevents the bending of the lifting rope from causing the object to shake.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a lifting safety fixing device, including an upper plate, a lower plate is provided at the bottom of the upper plate, and two clamping plates are symmetrically provided at the bottom of the lower plate, the clamping plates are transmission connected to the upper plate and the lower plate, a top plate is provided on the top of the upper plate, and a lifting rope is fixed at the center of the bottom of the top plate, a hook is fixed at the bottom of the lifting rope, a hanging ring is fixed on the top surface of the upper plate corresponding to the hook, and the hook is buckled inside the hanging ring, the top plate is located on both sides of the lifting rope and is rotatably installed with a telescopic rod through a rotating shaft, and the extended end of the telescopic rod is clamped and locked with the upper plate, a connecting block is fixed at the middle position on the back side of the lower plate, and a vertical screw is rotatably installed at the position of the upper plate corresponding to the connecting block through a bearing seat, and the connecting block is meshed and sleeved on the vertical screw.

[0007] Furthermore, two movable grooves are symmetrically opened on the surfaces of the lower plate and the upper plate, and movable blocks are slidably connected inside the movable grooves. Two vertical rods are fixed on the top of the clamping plate, and the vertical rods slide through the movable block of the lower plate and are fixed to the movable block of the upper plate.

[0008] Furthermore, a bidirectional screw is rotatably mounted inside the movable groove of the lower plate via a bearing, and two movable blocks of the lower plate are meshed and sleeved inside the movable groove.

[0009] Furthermore, elastic bands are fixed to the bottoms of the two clamping plates.

[0010] Furthermore, two plug plates are symmetrically fixed on the top of the upper plate, and an insert column is rotatably installed on the extended end of the telescopic rod through a rotating shaft, and the insert column can be slidably inserted into the inside of the plug plate.

[0011] Furthermore, a convex block is fixed on the surface of the convex column, and a convex groove is provided at the upper end of the insertion hole of the plug board, and the convex block can slide along the convex groove and pass through the plug board.

[0012] Furthermore, a locking bolt is engaged and inserted at the receiving end of the telescopic rod, and the locking bolt is in compression contact with the extended end of the telescopic rod.

Then the plug post is rotated to stagger the position of the protruding groove, so that the plug post and the plug board are locked by a card connection, which is convenient for later disassembly.

[0015] The utility model drives the moving blocks of the two lower plates to move along the moving grooves by rotating the bidirectional screw rod, and the moving block on the top of the vertical rod slides along the moving groove of the upper plate to adjust the spacing between the two clamping plates. The vertical screw rod is rotated, and the connecting block engages with the vertical screw rod to adjust the spacing between the upper plate and the lower plate. At the same time, the position of the bottom of the lower plate and the two clamping plates is adjusted to facilitate the clamping and wrapping of pipes of different sizes. The elastic sleeve at the bottom of the clamping plate is used to enhance the stability when clamping cylindrical objects.

[0016] Compared with the prior art, after the lifting rope is buckled with the upper plate, the telescopic rods on both sides are locked with the upper plate to form a triangular connection structure, so as to maintain stability during the lifting and transportation process, and the hard connection of the telescopic rods on both sides can prevent the bending of the lifting rope from causing shaking of the object.
