Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to an asymmetric component hoisting fixture and a hoisting device. Background Art

[0002] The X-shaped sling is a commonly used lifting fixture. Through the pulling force at the top of the X-shaped sling, a pair of clamps of the X-shaped sling provide clamping pressure on the hoisted component. The elastic blocks set in the pair of clamps convert the clamping pressure into friction force on the hoisted component, and the friction force offsets the gravity of the hoisted component.

[0003] For example, the utility model patent with the authorization announcement number CN213894915U discloses an X-shaped hoist for large components. The above solution solves the problem that the X-shaped hoist cannot hoist heavy precast concrete components. For symmetrical structural components with a large width, the hoisting work is mostly carried out based on the existing X-shaped hoisting equipment.

[0004] However, for asymmetric components with relatively narrow width, X-shaped slings are usually not able to directly lift them, such as Figure 1 As shown, this asymmetric component has a base portion, a vertical wall panel extends from one side of the base portion, and a bent plate extends from the top of the vertical wall panel toward the side of the base portion. For this type of asymmetric component, it is usually necessary to manually adjust the posture of the asymmetric component and tie it up with a sling, and lift the component by pulling the sling. After the component is lifted to the workbench, it is necessary to manually remove the sling wrapped around the component, which greatly reduces the work efficiency per unit time and increases the work intensity of the operators. In addition, the operators need to come into close contact with the large components when removing the slings, and also need to communicate with the overhead crane staff at a distance through gestures. If the communication is not timely, there will be certain safety hazards.

[0005] Therefore, it is urgent to develop a new lifting fixture on the existing basis for safe lifting of asymmetric components, which is conducive to improving the production efficiency of lifting work and reducing the time cost caused by adjusting the fixture and slings. Utility Model Content

The asymmetric component lifting fixtures are connected to the lower end of the lifting rope of the electric hoist through a lifting pin.

[0013] Preferably, the transverse movement mechanism of the lifting part includes a transverse movement guide, a bidirectional lead screw and a transverse movement drive motor. The bidirectional lead screw is rotatably installed in the transverse movement guide, the transverse movement drive motor is fixedly installed at the end of the transverse movement guide, and the output end of the transverse movement drive motor is drivingly connected to the end of the bidirectional lead screw; the bidirectional lead screw is provided with a forward thread section and a reverse thread section, and the two electric hoists are slidably fitted on the transverse movement guide through a base plate, and the two base plates are respectively fitted with the forward thread section and the reverse thread section through corresponding nut seats.

DETAILED DESCRIPTION

[0020] 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.

[0021] like Figure 1 The asymmetric component 100 shown has a base portion 101, a vertical wall panel 102 extends from one side of the base portion 101, and a bent plate 103 extends from the top of the vertical wall panel 102 toward the side of the base portion 101. For such an asymmetric component 100, it is usually necessary to manually adjust the posture of the asymmetric component 100, tie it up with a sling, and lift the component by pulling the sling.

[0022] See also Figures 1 to 3The utility model provides a technical solution: an asymmetric component lifting fixture, including a main body 2 and a hook lock 1, the main body 2 includes a lifting body 21, a vertical portion 22 is extended downward from the lower end of the lifting body 21 away from the hook lock 1, the vertical portion 22 is used to be attached to the side of the vertical wall plate 102 of the asymmetric component 100, and a lifting pin 4 for winding a lifting rope 5 is inserted at the upper end of the lifting body 21; the hook lock 1 includes a lower hook portion 11, the free end of the hook portion 11 is obliquely arranged upward toward the vertical portion 22, the hook portion 11 is used to hook the lower end of the bent plate 103 at the upper end of the asymmetric component 100, and an oblique arm portion 12 is extended from the upper end of the hook portion 11, and the oblique arm portion 12 is rotatably connected with the lifting body 21 through a horizontal pin 3.

[0023] The working principle of the utility model is: during hoisting, the lifting rope 5 is lowered so that the vertical part 22 is first abutted against the side of the vertical wall panel 102, and then, as the lifting rope 5 continues to descend, the free end of the hook part 11 first contacts the outer edge of the bending plate 103, and under the action of the bending plate 103, as the lifting rope 5 falls, the hook locking part 1 will rotate around the horizontal pin shaft 3 until the free end of the hook part 11 enters the lower end of the bending plate 103, and the hooking operation can be completed to meet the lifting state. As the lifting rope 5 rises, the asymmetric component 100 can be lifted. During the lifting process, the asymmetric component 100 is clamped by the cooperation of the hook locking part 1 and the main part 2, and the asymmetric component 100 can maintain its initial posture, which is convenient for accurately placing the asymmetric component 100 on the subsequent assembly workbench. The entire process does not require a sling to tie the component, and the operation is relatively more convenient and safer.

[0024] The lifting fixture of the utility model has a reasonable structural design, and does not require a sling binding operation. The asymmetric component 100 can be automatically hooked, and the hooking structure is stable and can meet the lifting state, which is beneficial to improving the production efficiency of the lifting work and reducing the time cost caused by adjusting the fixture and the sling. In addition, during the lifting process, the asymmetric component 100 can maintain the correct assembly position, which facilitates the accurate placement of the asymmetric component 100 on the subsequent assembly workbench, and the lifting operation is relatively more convenient and safer.

[0025] As a specific solution, under the premise of ensuring the structural strength of the main body 2, in order to reduce the weight of the main body 2, the main body 2 is composed of a pair of main body hangers, the main body hangers have corresponding hanging body parts 21 and vertical parts 22, and the two main body hangers are welded and connected by multiple stiffening fixing plates 23.

[0026] As a specific solution, under the premise of ensuring the structural strength of the hook locking component 1, in order to reduce the weight of the hook locking component 1, the hook locking component 1 is composed of a pair of hook locking hanger plates, the hook locking hanger plates have corresponding bent hook portions 11 and oblique arm portions 12, and the two hook locking hanger plates are welded and connected by multiple stiffening fixing plates 13.

[0027] In order to facilitate the hook locking member 1 to open automatically under the action of its own gravity during the hooking process, the bottom end height position of the vertical portion 22 is lower than the bottom end height position of the hook portion 11 .

[0028] For safe lifting of long asymmetric components 100, please refer to Figure 4 The present embodiment also provides an asymmetric component lifting device, including a pair of the asymmetric component lifting fixtures, a pair of electric hoists 6 and a lifting component transverse movement mechanism 200 for driving the electric hoists 6 to move toward or away from each other. The asymmetric component lifting fixture is connected to the lower end of the lifting rope 5 of the electric hoist 6 through the lifting pin 4, and the electric hoist 6 is used to control the lifting and lowering movement of the lifting rope 5 to lift the component. Among them, the transverse movement mechanism 200 of the lifting part includes a transverse movement guide 201, a bidirectional lead screw 202 and a transverse movement drive motor 203.
