Description

Technical Field

[0001] The utility model relates to the technical field of water hoisting, in particular to a lifting lug suitable for a barrel-type foundation structure. Background Art

[0002] The barrel-type foundation structure needs to be hoisted and installed by lifting equipment during production and installation. Due to the large size and weight of the barrel-type foundation structure, the existing lifting ears are usually fixed to the barrel-type foundation structure by bolts. Since the lifting ears are subjected to very large forces, the vertical friction between the bolts and the concrete alone can easily damage the concrete around the bolts, causing the bolts to loosen or even fall off, thereby posing a great safety hazard to the lifting operation; and the connection method of the existing lifting ears' lifting ropes is relatively simple, and it is necessary to select a corresponding connection method according to the structure of the lifting ears for connection, which has poor applicability. The pin shaft and the hanging plate are split designs. When the pin shaft is lost or damaged, it is necessary to re-equip the pin shaft, resulting in waste. Summary of the invention

[0003] In view of this, the utility model provides a lifting lug suitable for a barrel-type foundation structure, which has the characteristics of high strength, firm installation and wide applicability.

[0004] The utility model solves the above problems through the following technical means:

[0005] The utility model is applicable to the lifting ear of the barrel-type foundation structure, comprising a U-shaped embedded plate with two ends exposed from the concrete surface of the barrel-type foundation structure, a lifting ear body arranged between the two ends of the embedded plate, and a reinforcement mechanism for limiting the position arranged at the two ends of the embedded plate;

[0006] The lifting ear body includes a base plate, two parallel ear plates arranged at the upper end of the base plate, a pin installed on the ear holes of the two ear plates, two groups of stiffening plates arranged on the outer sides of the two ear plates and connected to the base plate, and a spacer block detachably installed between the two ear plates and matching the shape of the ear plates.

[0007] Preferably, the reinforcement mechanism includes two groups of limiting bolts arranged at the two ends of the embedded plate, limiting top blocks arranged at the ends of the two groups of limiting bolts for supporting the two ear plates, and fastening bolts arranged at the upper ends of the two limiting top blocks and inserted downward for tightening the base plate.

[0008] Preferably, each group of the stiffening plates comprises two triangular structures distributed on both sides of the ear hole, and the limiting top block is arranged between the two stiffening plates.

[0009] Preferably, a plurality of bolt holes arranged in a matrix are provided at corresponding positions of the embedded plate and the base plate, for inserting connecting bolts of the base plate and the embedded plate in sequence from top to bottom to fix the lifting ear body.

[0010] As a further improvement of the above technical solution, the spacer block is an inverted hook-shaped structure, and the outer side of the long end of the spacer block is hinged to the edge of the bottom plate, so that the spacer block can rotate around the edge of the bottom plate.

[0011] As a further improvement of the above technical solution, a limiting buckle is provided at the short end of the spacer, and a limiting slot is provided on the ear plate corresponding to the limiting buckle.

[0012] Preferably, a pull rope is provided at the limiting end of the pin shaft.

[0013] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0014] The utility model is suitable for the lifting ear of the barrel type foundation structure. The lifting ear body is reinforced by the embedded plate embedded in the concrete of the barrel type foundation structure to increase the lateral friction force, thereby improving the installation strength, avoiding the loosening or even falling off of the lifting ear body, and ensuring the construction safety. Moreover, when the pin shaft is lost or damaged, the spacer block can be installed between the two ear plates, and the lifting can be carried out by directly passing the hook through the ear hole or directly passing the lifting rope through the ear hole to fix it. The spacer block blocks and limits the ear plates on both sides to avoid the situation where the two ear plates are deformed inwardly due to excessive pressure during upper lifting. The utility model has a wider applicability and avoids the waste caused by re-distributing the pin shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0023] The utility model will be described in detail below with reference to the accompanying drawings. Figures 1 to 5 As shown: the lifting ear suitable for the barrel-type foundation structure described in this embodiment includes a U-shaped embedded plate 1 with two ends exposed from the concrete surface of the barrel-type foundation structure, an ear body 2 arranged between the two ends of the embedded plate 1, and a reinforcement mechanism 3 for limiting the position arranged at the two ends of the embedded plate 1; the ear body 2 includes a bottom plate 21, two parallel ear plates 22 arranged at the upper end of the bottom plate 21, a pin 23 installed on the ear holes of the two ear plates 22, two groups of stiffening plates 24 arranged on the outside of the two ear plates 22 and connected to the bottom plate 21, and a spacer 25 detachably installed between the two ear plates 22 and matching the shape of the ear plates 22.

[0024] The lifting ear suitable for the barrel-type foundation structure described in this embodiment is reinforced by the embedded plate 1 embedded in the concrete of the barrel-type foundation structure to reinforce the lifting ear body 2, thereby increasing the lateral friction force and improving the installation strength, avoiding the loosening or even falling off of the lifting ear body 2, and ensuring the construction safety; and when the pin shaft 23 is lost or damaged, the spacer 25 can be installed between the two ear plates 22, and the lifting can be carried out by directly passing the hook through the ear hole or directly passing the lifting rope through the ear hole to fix it. The spacer 25 blocks and limits the ear plates 22 on both sides to avoid the situation where the two ear plates 22 are deformed inward due to excessive pressure from the upper end during lifting. The applicability is wider and the waste caused by re-distributing the pin shaft 23 can be avoided.

[0025] When pouring the barrel-type foundation structure, the embedded plate 1 is embedded in the designed position. During installation, the bottom plate 21 of the lifting ear body 2 is first placed between the ends of the embedded plate 1 on the upper part of the concrete surface, and the lifting ear body 2 is limited and reinforced by the reinforcement mechanism 3, and then a plurality of connecting bolts 5 are passed through the bottom plate 21 and the bottom of the embedded plate 1 from top to bottom to fix them, and finally the pin shaft 23 is passed through the two ear plates 22 and limited.

[0026] As a preferred implementation of the above technical solution, the reinforcement mechanism 3 includes two groups of limiting bolts 31 arranged at the two ends of the embedded plate 1, limiting top blocks 32 arranged at the ends of the two groups of limiting bolts 31 for supporting the two ear plates 22, and fastening bolts 33 arranged at the upper ends of the two limiting top blocks 32 and inserted downward for tightening the bottom plate 21. The limiting top blocks 32 are controlled by the limiting bolts 31 to support the ear plates 22 for front and rear limiting, and the wide sides of the embedded plate 1 and the wide sides of the lifting ear body 2 are used to limit the left and right sides, thereby ensuring that the lifting ear body 2 and the embedded plate 1 correspond to each other up and down, so that the connecting bolts 5 can be smoothly driven into the bottom of the bottom plate 21 and the embedded plate 1, and the fastening bolts 33 can apply downward pressure to the upper surface of the bottom plate 21, thereby further enhancing the installation strength.

[0027] As a preferred implementation of the above technical solution, each group of the stiffening plates 24 includes two triangular structures distributed on both sides of the ear hole, and the limiting top block 32 is arranged between the two stiffening plates 24, so that the ear body 2 can be easily limited to the left and right, thereby improving the installation efficiency.

[0028] To facilitate installation, as a preferred implementation of the above technical solution, a plurality of bolt holes 4 arranged in a matrix are provided at corresponding positions of the embedded plate 1 and the base plate 21, which are used to insert the connecting bolts 5 of the base plate 21 and the embedded plate 1 in sequence from top to bottom to fix the lifting ear body 2.

[0029] As a further improvement of the above technical solution, the spacer block 25 is a hook-shaped structure, and the outer side of the long end of the spacer block 25 is hinged to the edge of the base plate 21, so that the spacer block 25 can rotate around the edge of the base plate 21. When the pin shaft 23 is used to wrap the wire rope of the lifting equipment, the spacer block 25 is rotated open and will not hinder the lifting operation. When the wire rope is directly passed through the ear hole for lifting or the hook is directly passed through the ear hole for lifting, the spacer block 25 is rotated closed and the two ear plates 22 are limited. It is easy to change the installation form of the spacer block 25, and the installation efficiency is high.

[0030] To facilitate installation and fixation, as a further improvement of the above technical solution, a limiting buckle (not shown in the figure) is provided at the short end of the spacer block 25, and a limiting slot (not shown in the figure) is provided on the ear plate 22 corresponding to the limiting buckle. When the spacer block 25 is closed, it is easy to fix it with the ear plate 22 to avoid the spacer block 25 from falling out due to lifting and shaking.

[0031] In order to facilitate the unwinding, as a preferred implementation of the above technical solution, a pull rope 26 is provided at the limiting end of the pin shaft 23, and the construction personnel do not need to be next to the lifting lug, and can unwind the cable by simply pulling the pull rope 26.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
