Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a cross hoisting sling. Background Art

[0002] During the installation of large equipment and structures, each component needs to be hoisted and installed, usually using a crane and steel ropes.

[0003] At present, due to the huge size of large components, the steel ropes are subjected to great force during the lifting process. The force on the hoisted components can be decomposed into vertical upward pulling force and horizontal inward squeezing force. Due to the existence of squeezing force, the hoisted components are prone to deformation during the installation process, which ultimately affects the quality of construction. Utility Model Content

[0004] The utility model aims to provide a cross hoisting sling with the advantages of simple structure and easy use, and solves the problem that due to the huge size of large components, the steel rope is subjected to large force during the hoisting process, and the force of the hoisting components can be decomposed into vertical upward pulling force and horizontal inward squeezing force. Due to the existence of squeezing force, the hoisting components are easily deformed during the installation process, which ultimately affects the quality of construction.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cross lifting sling, comprising a central frame and a double-hole lifting ear, the double-hole lifting ear is installed on the central frame and connected to the central frame by sliding fit, a steel rope is arranged on the top of the double-hole lifting ear, a crane is arranged on the top of the steel rope, a lifting component is arranged on the bottom of the double-hole lifting ear, the central frame is made of channel steel, the central frame is a centrally symmetrical cross, the central frame is a centrally symmetrical shape, and a lifting ear hole is respectively provided at the upper and lower ends of the double-hole lifting ear.

[0006] As a preferred solution, the double-hole lifting lug is symmetrical.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] 1. The utility model is provided with double-hole lifting ears, which can slide along the central frame as needed, so that the hoisted object is completely subjected to the vertical upward pulling force, avoiding the phenomenon of the hoisted object being compressed and deformed, effectively ensuring the construction quality, and thus effectively improving the practicability of the equipment.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-3 The utility model: a cross lifting sling, comprising a central frame 1 and a double-hole lifting ear 2, the double-hole lifting ear 2 is installed on the central frame 1 and connected to the central frame 1 by sliding fit, a steel rope 3 is arranged on the top of the double-hole lifting ear 2, a crane 5 is arranged on the top of the steel rope 3, a lifting member 4 is arranged on the bottom of the double-hole lifting ear 2, the central frame 1 is made of channel steel, the central frame 1 is a centrally symmetrical cross, the central frame 1 is a centrally symmetrical shape, and a lifting ear hole is respectively provided at the upper and lower ends of the double-hole lifting ear 2.

[0017] The working principle of the utility model is: Figure 3 As shown, the upper hole of the double-hole lifting ear 2 of the lifting sling is connected to the hook of the crane 5 through the steel rope 3, and the lower hole of the double-hole lifting ear 2 is connected to the lifting component 4 through the steel rope 3. The position of the double-hole lifting ear 2 is adjusted by sliding along the central frame 1, so that the steel rope 3 between the double-hole lifting ear 2 and the lifting component 4 is in a vertical horizontal plane, ensuring that the lifting component 4 is only subjected to vertical upward tension to prevent it from being compressed and deformed. The crane 5 is started to pull up the steel rope 3 for lifting construction.

[0018] 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 the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
