Description

Technical Field

[0001] The utility model relates to the technical field of pipeline hoisting, in particular to a socket-type concrete pipe sling. Background Art

[0002] The hoisting of reinforced concrete pipes is an important link in the pipeline installation construction process. The most commonly used method in pipeline hoisting is ordinary strap hoisting, which requires multiple people to cooperate to complete, is time-consuming and laborious, and increases the danger of operators in the deep trench space. The construction operation area is in the deep trench of the pipeline. When hoisting the pipeline with ordinary straps, it needs to move back and forth to align, which is inconvenient, time-consuming and laborious, and increases the construction cost. When using ordinary straps to fix the interfaces of reinforced concrete pipes in the deep foundation pit where the construction operation surface of the reinforced concrete pipes is located, it will increase the number of construction workers and labor. When the construction of the reinforced concrete pipes is in a deep foundation pit with a depth of 3 - 5m, when the depth of the foundation pit is too high, the danger coefficient of the operators will increase during the construction process.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1 to 3 shown, a socket-type concrete pipe lifting tool includes a pipe support 1 and a hook connection 2. The pipe support 1 includes an insertion part 1.1 for inserting into the pipe opening and a connection part 1.2 for connecting the hook. When the insertion part 1.1 is inserted into the pipe, the connection part 1.2 is located outside the pipe. The pipe support 1 is inserted into the interior of the concrete pipe through the insertion part 1.1 to achieve a stable connection between the lifting tool and the concrete pipe. The connection part 1.2 is located outside the pipe to limit the pipe orifice. The hook connection 2 is used to connect the wire rope buckle, thereby realizing the lifting of the concrete pipe.

[0021] At the top of the connecting part 1.2, a plate body part 3 extends horizontally towards the insertion part 1.1. The length of the plate body part 3 is the same as that of the insertion part 1.1, and the hook connecting piece 2 is fixedly connected to the top of the plate body part 3. The plate body part 3 provides an installation platform for the hook connecting piece 2. Through the plate body part 3, a more stable connection structure is formed between the hook connecting piece 2 and the pipe support 1, enhancing the overall stability of the lifting tool and ensuring safety during the lifting process.

[0022] The insertion part 1.1, the connecting part 1.2, and the plate body part 3 are all rectangular steel plates, and the insertion part 1.1, the connecting part 1.2, and the plate body part 3 are integrally formed. The plate body part 3 and the insertion part 1.1 are respectively located at both ends of the connecting part 1.2, and the connecting part 1.2 is perpendicular to the insertion part 1.1. The rectangular steel plate has high strength and stability, can bear large loads, ensuring the strength and durability of the lifting tool. The integrally formed design reduces the connection points between components, improving the strength and reliability of the overall structure, increasing the service life of the lifting tool. The connecting part 1.2 being perpendicular to the insertion part 1.1 makes the lifting tool more smooth when inserted into the concrete pipe and ensures stability during the lifting process.

[0023] The hook connecting piece 2 includes a first lifting ear 2.1 and a second lifting ear 2.2. In the extending direction of the plate body part 3, an angle is formed between the first lifting ear 2.1 and the plate body part 3, and the angle is an acute angle. The second lifting ear 2.2 is parallel to the plate body part 3. The first lifting ear 2.1 and the second lifting ear 2.2 provide two lifting points, increasing the stability and safety of the lifting. The acute angle formed between the first lifting ear 2.1 and the plate body part 3 facilitates the connection and disconnection of the wire rope buckle. The second lifting ear 2.2 being parallel to the plate body part 3 further increases the stability during the lifting process.

[0024] The first lifting ear 2.1 is a semi-circular structural steel plate, and the second lifting ear 2.2 is a rectangular steel plate. The first lifting ear 2.1 is located at the front end of the plate body part 3, and the second lifting ear 2.2 is located at the tail end of the plate body part 3. The first lifting ear 2.1 and the second lifting ear 2.2 are respectively located at the front end and the tail end of the plate body part 3, jointly bearing the load during the lifting process.

[0025] Snap holes 4 are provided on both the first lifting ear 2.1 and the second lifting ear 2.2. Through the design of the snap holes 4, the wire rope buckle is connected more firmly and reliably, avoiding the risk of the wire rope buckle falling off during the lifting process.

[0026] A plurality of snap holes 4 are arranged in sequence along the horizontal direction on the second lifting ear 2.2. By arranging a plurality of snap holes 4 along the horizontal direction on the second lifting ear 2.2, the connection position of the wire rope buckle can be adjusted according to actual needs, improving the flexibility and adaptability of the lifting.

[0027] Before carrying out the hoisting operation, first insert the insertion part 1.1 of the pipe support 1 into both ends of the concrete pipe, ensure that the insertion part 1.1 fits tightly against the inner wall of the pipe, so that the connection part 1.2 abuts against the upper end of the pipe orifice. Pass the wire rope buckle through the buckle holes 4 on the first lifting lug 2.1 and the second lifting lug 2.2. The connection position of the wire rope buckle in the buckle hole 4 of the second lifting lug 2.2 can be adjusted according to the diameter of the reinforced concrete pipe. Finally, connect it with the external hoisting equipment through the wire rope buckle and start the hoisting operation.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
