Description

Technical Field

[0001] The utility model relates to the field of sling equipment, and more specifically, to a sling used for an automobile. Background Art

[0002] A sling is a device used in lifting machinery to lift heavy objects. The most commonly used sling for lifting finished items is a hook, and there are other slings such as lifting rings, lifting suction cups, clamps, and forks. Lifting suction cups, clamps, and forks can be used as special slings on cranes for a long time, or as replaceable auxiliary slings hung on hooks for temporary use. They are often used in warehouses and yards with multiple types of goods to improve work efficiency. Lifting slings for automobiles can be used for rescue operations when the vehicle encounters an abnormal situation.

[0003] However, the rescue hoist used for the car does not form a vertical contact force between the lifting crossbeam and the rescued car body, which leads to a large swing range of the upper hanging rope and the lower hanging rope, which is not conducive to ensuring the stability of the rescued car body during the lifting process. Therefore, it is necessary to design a more stable car hoist for rescue to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a hoist for automobiles. This scheme can utilize the electric push rod under the lifting beam to drive the negative pressure suction cup to move downward until it contacts the roof position of the lower hanging rope, thereby forming a vertical abutment force between the lifting beam and the rescued vehicle body, reducing the shaking range of the upper hanging rope and the lower hanging rope, which is beneficial to ensuring the stability of the lifting process of the rescued vehicle body.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A lifting device for an automobile comprises a lifting rope, wherein the lower end of the lifting rope is fixedly connected to a lifting hook, upper hanging ropes are symmetrically arranged at the left and right ends of the lower end of the lifting hook, a lifting crossbeam is arranged at the lower ends of the two upper hanging ropes, arc-shaped rings are symmetrically fixedly connected to the left and right ends of the lifting crossbeam, the two arc-shaped rings at the upper end are bound to the upper hanging ropes, the lower ends of the two arc-shaped rings at the lower end are respectively bound to a pair of lower hanging ropes, an electric push rod is fixedly connected to the middle part of the lower end of the lifting crossbeam, and a negative pressure suction cup is fixedly connected to the output end of the electric push rod.

[0009] Furthermore, the lower ends of the plurality of lower hanging ropes are hoisted with the rescued vehicle body.

[0010] Furthermore, the negative pressure suction cup is in contact with the upper end of the rescued vehicle body, and a buffer layer is fixedly connected between the output end of the electric push rod and the negative pressure suction cup.

[0011] Furthermore, distance sensors are fixedly connected to the left and right sides of the lower end of the lifting crossbeam, and the two distance sensors are respectively located on the left and right sides of the electric push rod.

[0012] Furthermore, the outer ends of the upper hanging rope and the lower hanging rope are fixedly connected with anti-warning light outer strips.

[0013] Furthermore, the outer ends of the lower hanging rope belts of the upper hanging rope belts are slidably connected with a plurality of anti-wear outer sliding sleeves.

[0014] Furthermore, a plurality of anti-wear outer sliding sleeves are respectively in contact with the hook, the arc-shaped ring and the lower hanging rope belt, and the hanging rope is externally connected to a crane.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) Before the rescued vehicle is lifted, the electric push rod under the lifting beam can be used to drive the negative pressure suction cup to move downward until it contacts the roof position of the lower hanging rope, thereby forming a vertical contact force between the lifting beam and the rescued vehicle. Then, during the process of lifting the lower hanging rope in the air, the swing range of the upper hanging rope and the lower hanging rope is reduced, which is beneficial to ensure the stability of the lifting process of the rescued vehicle and make it more accurately docked when it is close to the lifting and unloading location.

[0018] (2) At the same time, during the lifting process of the upper hanging rope and the lower hanging rope, a plurality of slidable anti-wear outer sliding sleeves can be arranged outside the upper hanging rope and the lower hanging rope. The anti-wear outer sliding sleeves can be slid to the contact position between the upper hanging rope and the lower hanging rope and the hard point during the assembly process of the upper hanging rope and the lower hanging rope by the staff, thereby reducing the strong wear force on the upper hanging rope and the lower hanging rope during the lifting process, which is beneficial to ensure the service life of the upper hanging rope and the lower hanging rope.

[0019] (3) At the same time, during the lifting process of the upper hanging rope and the lower hanging rope, by setting anti-warning light outer strips outside the upper hanging rope and the lower hanging rope, the workers can more clearly know the lifting position of the rescued vehicle in a dim environment, making the use process more humane.
