Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, specifically a special lifting device for emergency rescue small cars. Background Technology

[0002] In my country, small cars are flexible to drive and widely applicable (such as family sedans, SUVs, MPVs, etc.), and are the mainstream models for daily travel, family use and urban logistics. When small cars break down or are involved in an accident and cannot be moved, they usually need to be lifted by a crane using a lifting device.

[0003] Currently, in pursuit of wide applicability, the slings use fixed support components for through channels. However, the fixed support components are mismatched with the curved surface of the small car chassis, resulting in insufficient contact area and large offset of the support points. This leads to stress concentration and easy damage to the vehicle body. In addition, the single mechanical locking mechanism has a high probability of slippage under tilted conditions. Furthermore, in terms of space, the large unfolding size often cannot meet the needs of working in confined spaces, and frequent adjustments reduce rescue efficiency. Utility Model Content

[0004] To address the problems of uneven stress distribution leading to secondary damage and the inconvenience of large-sized lifting devices in confined spaces, the purpose of this utility model is to provide a special lifting device for small cars used in emergency rescue.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a special lifting tool for emergency rescue small cars, including a sling and a clamp, the clamp including a lower clamp and an upper clamp, the lower clamp and the upper clamp being symmetrically distributed, the dimensions of the lower clamp and the upper clamp being 200×150×100mm, a sling groove being provided on the opposite side of the lower clamp and the upper clamp, one end of the sling movably passing through the sling groove, a lifting ring being fitted on the end of the sling near the clamp, the end of the sling away from the clamp movably passing through the lifting ring, a wooden wedge being movably inserted inside the lifting ring, a threaded pin being threaded into one end of the lifting ring, the lifting ring being easily removed from the sling by disassembling through the threaded pin, and a lifting port being provided on the end of the sling away from the clamp;

[0006] Preferably, a connecting rope is fixedly provided at the top of the wooden wedge, with one end of the connecting rope sleeved on the outside of the lifting ring. This connecting rope prevents the wooden wedge from being easily lost. A cut-resistant rubber sleeve is fixedly provided on the outside of the lifting strap to prevent scratches or cuts from car wheel hubs. Both the lower and upper clamps include a high-density EVA foam core and a carbon fiber shell. The carbon fiber shell is located outside the high-density EVA foam core. The high-density EVA foam core has excellent energy absorption and cushioning performance, serving as a support core, dispersing external impact forces, reducing overall weight, and providing a certain structural rigidity. The carbon fiber shell has high strength, corrosion resistance, and fatigue resistance. The outer protective layer bears the main load and enhances the overall bending and impact resistance. The sling is made through a multi-fiber layer lamination process, which increases the load-bearing capacity of the sling, ensures uniform load distribution, and reduces the risk of single-layer breakage. The wooden wedge is an isosceles trapezoid with dimensions of 3cm for the upper base, 5cm for the lower base, and 15cm for the height. The isosceles trapezoid structure allows for easy insertion and fixing of the lifting ring. The upper surface of the lower clamp is fixed with screws arranged in a rectangular array. One end of each screw movably passes through the upper clamp, and a nut is threaded onto the top of each screw. The lower and upper clamps can be locked and fixed by the cooperation of the screws and nuts.

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

[0008] Non-contact geometric connection avoids secondary damage caused by traditional clamping and hoisting. The clamps distribute the load through a wide contact surface and the slings do not contact the vehicle body frame, thus avoiding structural deformation of the vehicle. The modular and independent design of slings, clamps, and lifting rings can shorten the installation time of the lifting equipment. At the same time, the modular design can adapt to working conditions in narrow spaces such as narrow passages, thus increasing the applicability of the lifting equipment. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3 As shown, this utility model provides a special lifting tool for emergency rescue small cars, including a sling 1 and a clamp. The clamp includes a lower clamp 2 and an upper clamp 3, which are symmetrically distributed. The dimensions of the lower clamp 2 and the upper clamp 3 are 200×150×100mm. A sling groove 5 is provided on one side of each of the lower clamp 2 and the upper clamp 3. One end of the sling 1 passes through the sling groove 5. A lifting ring 4 is fitted onto the end of the sling 1 near the clamp, and the end of the sling 1 away from the clamp passes through the lifting ring 4. A wooden wedge 7 is inserted into the inside of the lifting ring 4. Wooden wedges 7 are used to fill the gap between the sling 1 and the lifting ring 4, which can fix the sling 1. One end of the lifting ring 4 is threaded with a threaded pin 8. The lifting ring 4 can be easily removed from the sling 1 by disassembling the threaded pin 8. The end of the sling 1 away from the clamp is provided with a lifting port 6. By passing one end of the sling 1 through and fitting it onto the wheel hub of the vehicle, and then passing the other end of the sling 1 through the lifting ring 4, the sling 1 can be hung on the hook of the crane through the lifting port 6. The wheel hub is lifted by four lifting tools, which can keep the lifting stable and avoid damage to the vehicle.

[0016] A connecting rope 12 is fixedly installed at the top of the wooden wedge 7. One end of the connecting rope 12 is sleeved on the outside of the lifting ring 4. The connecting rope 12 can prevent the wooden wedge 7 from being easily lost. A cut-resistant rubber sleeve 11 is fixedly sleeved on the outside of the sling 1. The cut-resistant rubber sleeve 11 can prevent the sling 1 from being scratched or cut by the car wheel hub. Both the lower clamp 2 and the upper clamp 3 include a high-density EVA foam core and a carbon fiber shell. The carbon fiber shell is set on the outside of the high-density EVA foam core. The high-density EVA foam core has excellent energy absorption and cushioning performance. As a support core, it disperses external impact force, reduces overall weight, and provides a certain structural rigidity. The carbon fiber shell has high strength, corrosion resistance, and fatigue resistance. The outer protective layer bears the main load and enhances the overall bending and impact resistance. The sling 1 is made by multi-fiber layer lamination process, which can increase the load-bearing capacity of the sling 1, ensure uniform load distribution and reduce the risk of single-layer breakage. The wooden wedge 7 is an isosceles trapezoidal structure with the following dimensions: upper base 3cm, lower base 5cm and height 15cm. The isosceles trapezoidal structure allows for easy insertion and fixing of the lifting ring 4. The upper surface of the lower clamp 2 is fixed with screws 9 arranged in a rectangular array. One end of the screw 9 moves through the upper clamp 3, and the top of the screw 9 is threaded with a nut 10. The lower clamp 2 and the upper clamp 3 can be locked and fixed by the cooperation of the screw 9 and the nut 10.

[0017] Working principle: First, the sling 1 is passed through the sling groove 5 between the lower clamp 2 and the upper clamp 3. Then, the lower clamp 2 and the upper clamp 3 are locked and fixed by the screw 9 and the nut 10. Next, one end of the sling 1 is passed through the wheel hub of the vehicle, and the cut-resistant rubber sleeve 11 of the sling 1 is placed at the contact point with the wheel hub. This can protect the wheel hub and the sling 1. Then, one end of the sling 1 is passed through the lifting ring 4, and a wooden wedge 7 is inserted into the lifting ring 4. The wooden wedge 7 fills the gap between the sling 1 and the lifting ring 4, which can fix the sling 1. This makes it easy to install the lifting device on the wheel hub. Repeat the above operation to install the four lifting devices on the four wheel hubs of the vehicle. Then, the lifting ports 6 of the four slings 1 are put on the crane hook, so that the crane can lift the vehicle for rescue. By fixing the four lifting devices to the wheel hub, the vehicle can be lifted to avoid structural deformation. This can maintain the stability of the lifting and avoid damage to the vehicle.
