Description

Technical Field

[0001] This utility model relates to the technical field of hoisting tools for building construction, specifically a steel bar bundling hoisting clamp. Background Technology

[0002] During construction, a large amount of steel reinforcement is required. For construction sites such as high-rise buildings, the steel reinforcement must first be bundled and hoisted to the construction section. The traditional hoisting method is to use two steel wire ropes to thread the bundle of steel reinforcement through, tie it together, and then hoist it. There are also special hoisting clamps to hold the steel reinforcement in place. However, the end of the clamp that holds the steel reinforcement is often rigid. When the steel reinforcement is placed on the ground rather than on a scaffold, these hoisting clamps cannot extend the clamping end under the steel reinforcement. This can easily lead to the bottom one or several steel reinforcements not being held, requiring manual re-stacking. However, longer steel reinforcements are heavier, and a single person cannot stack them, increasing the waste of manpower. Utility Model Content

[0003] The purpose of this utility model is to provide a steel bar bundling hoisting clamp to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rebar bundling hoisting clamp, comprising an S-shaped bend plate one and an S-shaped bend plate two, wherein the middle portions of the S-shaped bend plate one and the S-shaped bend plate two are hinged by a pin; the S-shaped bend plate one comprises an upper half bend plate one and a lower half bend plate one; the S-shaped bend plate two comprises an upper half bend plate two and a lower half bend plate two; a channel one is fixedly provided near the bottom of the upper half bend plate two; a channel two is fixedly provided near the bottom of the lower half bend plate one; and a channel three is fixedly provided near the top of the upper half bend plate two; connecting steel wire ropes pass through the channels one, two, and three; a steel wire rope knot is tied at the bottom of the connecting steel wire rope; and the top of the connecting steel wire rope is secured by the steel wire rope knot.

[0005] Furthermore, both the lower half-bent plate one and the lower half-bent plate two have an inwardly curved extension at their bottom ends.

[0006] Furthermore, the inner sides of both the lower half-bent plate one and the lower half-bent plate two are provided with anti-slip textures.

[0007] Furthermore, a guide rail is fixedly installed on the outer side of the lower half-bent plate. The guide rail is arc-shaped, and the connecting steel wire rope is slidably arranged inside the guide rail.

[0008] Furthermore, the top ends of the first and second upper curved plates are connected to both ends of the same traction rope, and a lifting ring is fitted on the traction rope.

[0009] Furthermore, the clamp consisting of S-shaped bend plate one and S-shaped bend plate two is provided, and each of the two clamps has a second lifting ring on the corresponding lifting ring one. The two second lifting rings are fixedly connected to the two ends of the same traction rope, and the traction rope is fitted with a third lifting ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Before hoisting, pass the end of the connecting wire rope without the wire rope knot through the first channel, then through the bottom of the rebar pile. Then, pass the connecting wire rope through the second and third channels in sequence, and use the wire rope clip to tighten the connecting wire rope. This will compensate for the problem that the S-shaped bend plate one and S-shaped bend plate two cannot hold the bottom rebar. When hoisting the S-shaped bend plate one and S-shaped bend plate two, rotate them so that the bottom of the upper half of the bend plate two and the lower half of the bend plate one gradually move closer together, and then tighten the rebar.

[0012] 2. The pile of steel bars is clamped and hoisted by the clamp composed of S-shaped bend plate one and S-shaped bend plate two. When the top of the upper half bend plate one and upper half bend plate two is subjected to traction force, S-shaped bend plate one and S-shaped bend plate two will rotate to clamp the steel bars. The heavier the steel bar, the greater the clamping force to ensure the clamping effect.

[0013] 3. Two sets of clamps can clamp the steel bars at different positions to ensure stability during hoisting. The hoisting equipment lifts the third lifting ring, which in turn lifts the two second lifting rings at the same time. The second lifting ring lifts the first lifting ring, which in turn lifts the clamp consisting of the first and second S-shaped bend plates. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a rebar bundling hoisting clamp, including an S-shaped bend plate 1 and an S-shaped bend plate 2. The middle parts of the S-shaped bend plate 1 and the S-shaped bend plate 2 are hinged by a pin. The S-shaped bend plate 1 includes an upper half bend plate 101 and a lower half bend plate 102. The S-shaped bend plate 2 includes an upper half bend plate 201 and a lower half bend plate 202. A channel 1 301 is fixedly provided near the bottom of the upper half bend plate 201. A channel 2 302 is fixedly provided near the bottom of the lower half bend plate 102. A channel 3 303 is fixedly provided near the top of the upper half bend plate 201. A connecting steel wire rope 3 passes through the channel 1 301, channel 2 302, and channel 3 303. A steel wire rope knot 305 is tied at the bottom of the connecting steel wire rope 3. The top of the connecting steel wire rope 3 is tied tightly by the steel wire rope knot 305. The clamping device composed of S-shaped bend plate 201 and S-shaped bend plate 202 is used to clamp and lift the pile of steel bars. When the top of the upper half-bend plate 101 and the upper half-bend plate 201 is subjected to traction, the S-shaped bend plate 11 and S-shaped bend plate 202 will rotate to clamp the steel bars. The heavier the steel bars, the greater the clamping force to ensure the clamping effect. Before lifting, the end of the connecting wire rope 3 without the wire rope knot 305 is passed through the channel 1 301 and then through the bottom of the steel bar pile. Then, the connecting wire rope 3 is passed through the channel 2 302 and the channel 3 303 in sequence, and then the connecting wire rope 3 is tied tightly with the wire rope buckle 304. This makes up for the problem that the S-shaped bend plate 11 and S-shaped bend plate 202 cannot clamp the bottom steel bars. When the S-shaped bend plate 11 and S-shaped bend plate 202 rotate during lifting, the bottom of the upper half-bend plate 201 and the lower half-bend plate 102 gradually move closer and then clamp the steel bars.

[0021] Both the bottom ends of the lower half-bent plate 102 and the lower half-bent plate 202 are provided with inwardly curved extensions. By using the flat and long extensions, they can better extend under the reinforcing bars when the lower half-bent plate 102 and the lower half-bent plate 202 are rotated and snapped together.

[0022] The inner sides of both the lower half-bend plate 102 and the lower half-bend plate 202 are provided with anti-slip textures. The anti-slip textures can effectively increase the friction between the lower half-bend plate 102 and the lower half-bend plate 202 and the reinforcing bars, and can effectively prevent the reinforcing bars from slipping.

[0023] A guide rail 4 is fixedly installed on the outer side of the lower half-bend plate 102. The guide rail 4 is arc-shaped, and the connecting steel wire rope 3 is slidably set inside the guide rail 4. The guide rail 4 guides the connecting steel wire rope 3 to prevent the connecting steel wire rope 3 from sliding, which would prevent it from failing to support and limit the steel bars.

[0024] The top ends of the upper half-bend plate 101 and the upper half-bend plate 201 are connected to the two ends of the same traction rope, and the traction rope is fitted with a lifting ring 5. By lifting the lifting ring 5 with the hoisting equipment, the clamp composed of the S-shaped bend plate 1 and the S-shaped bend plate 2 can be lifted, so that the top ends of the upper half-bend plate 101 and the upper half-bend plate 201 are subjected to force, and then the S-shaped bend plate 1 and the S-shaped bend plate 2 rotate to clamp the steel bar.

[0025] There are two clamps consisting of S-shaped bend plate 1 and S-shaped bend plate 2. Each clamp has a lifting ring 6 on its corresponding lifting ring 5. The two lifting rings 6 are fixedly connected to both ends of the same traction rope, and the traction rope is fitted with a lifting ring 7. The two clamps can clamp the steel bar stack at different positions to ensure stability during the hoisting process. The hoisting equipment lifts the lifting ring 7, which in turn lifts the two lifting rings 6 at the same time. The lifting rings 6 lift the lifting ring 5, which in turn lifts the clamp consisting of S-shaped bend plate 1 and S-shaped bend plate 2.

[0026] Working principle: When in use, the end of the connecting wire rope 3 without the wire rope knot 305 is passed through the first channel 301, and then through the bottom of the rebar pile. Then, the connecting wire rope 3 is passed through the second channel 302 and the third channel 303 in sequence. The connecting wire rope 3 is then tied tightly with the wire rope clip 304. This compensates for the problem that the S-shaped bend plate 1 and the S-shaped bend plate 2 cannot hold the bottom rebar. When the S-shaped bend plate 1 and the S-shaped bend plate 2 are hoisted, they are rotated, which makes the bottom of the upper half bend plate 201 and the lower half bend plate 102 gradually move closer together, and then the rebar is locked.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
