Description

Technical Field

[0001] The utility model belongs to the technical field of passenger car transportation and loading, and relates to a wheel fixing device used for passenger car loading and transportation. Background Art

[0002] A flatbed cart is a special means of transport that can be used to transport passenger cars. After the passenger car is parked on the flatbed cart, in order to ensure the stability of the passenger car during transportation, the traditional wheel fixing method uses seat belts or ropes to fix the wheels. Although it is simple and easy, it has some disadvantages such as labor-intensive, limited fixation and difficult adjustment.

[0003] For example, a Chinese patent with application number 202010514759.7 discloses a multifunctional adjustable vehicle carrier and transport vehicle, including a vehicle body, on which a wheel fixing device is arranged, including a driving mechanism arranged on a lower parking plate and a clamping and fixing mechanism arranged on the driving mechanism, and the clamping and fixing mechanism is specifically located on the side of the lower parking plate; the clamping and fixing mechanism includes a pillar, a circular disc arranged on the top of the pillar, and a flexible clamping claw arranged on the circular disc, and the flexible clamping claw is provided with at least two groups, and the multiple groups of flexible clamping claws are centered on the center of the circular disc, and the circular disc is aligned with the wheel of the vehicle; the driving mechanism drives the arc of the pillar toward or away from the vehicle wheel until the multiple groups of flexible clamping claws are clamped on the vehicle wheel.

[0004] In the above scheme, the wheel is mainly clamped by flexible clamps. Since the circular disk on the top of the pillar is in a fixed state, the control of each joint of the flexible clamp needs to be more precise during the process of clamping the wheel, which is not easy to control. If the connection at the joint is loose, the combined force of the clamp will be greatly reduced, which may easily cause shaking during transportation. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a wheel fixing device for loading and transporting passenger cars. The technical problem to be solved by the utility model is: how to improve the convenience and stability of the wheel fixing device.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] A wheel fixing device for loading and transporting passenger cars comprises a base and two clamping arms, wherein a support frame is provided on the base, and the characterised in that the support frame has a first guide groove arranged in a vertical direction, the support frame is provided with a lifting plate which is slidably connected to the first guide groove up and down, the support frame is connected with a driving mechanism which can drive the lifting plate to move up and down, the support frame is provided with two symmetrically arranged swing arms which can swing up and down simultaneously, one end of the two swing arms is hinged to the support frame, the two clamping arms are respectively and vertically arranged at the other ends of the two swing arms, the two swing arms are movably connected to the lifting plate, and the two swing arms can swing up and down synchronously following the movement of the lifting plate.

[0008] After the passenger car is parked on the flatbed truck, the driving mechanism drives the lifting plate to move upward, thereby driving the swing arm to swing upward. The two clamping arms follow the swing arm to swing upward and contract radially to press on both sides of the wheel to hold the wheel tightly, thereby locking the wheel of the passenger car. The lifting plate and the swing arm are connected by the driving mechanism so that the entire swing arm can move upward and unfold stably. The support frame provides a good support foundation, reducing the shaking and swaying of the device during transportation. The clamping arm can also be retracted as the swing arm swings downward, so that the vehicle can drive in more conveniently, improving the convenience of using the device. The first guide groove forms a sliding guide for the lifting plate. When the lifting plate moves up and down, the two swing arms move synchronously, so that the clamping force is evenly applied to the wheel, providing a more stable fixing effect.

[0009] In the above-mentioned wheel fixing device for loading and transporting passenger cars, the support frame has two plate-shaped guide parts which are arranged in correspondence with each other at vertical intervals, the lifting plates have two guide parts which are arranged in correspondence outside the two guide parts, the two guide parts have the first guide groove, an intermediate connecting piece is arranged between the two lifting plates, the two lifting plates are fixedly connected to the intermediate connecting piece by a fixing pin which passes through the corresponding first guide groove, the driving mechanism is an oil cylinder, and the piston rod of the oil cylinder is connected to the intermediate connecting piece. The two lifting plates are synchronously linked by the intermediate connecting piece, and when the driving mechanism drives the intermediate connecting piece to move, the two lifting plates move synchronously, and through the two guide parts which are arranged at intervals, the thrust received by the swing arm is more uniform and stable, and the cooperation between the guide part and the first guide groove reduces the sway and shaking generated during the movement, and the structure is simple, reliable and highly stable.

[0010] In the above-mentioned wheel fixing device for loading and transporting passenger cars, the two swing arms are provided with long strip-shaped slide grooves along the length direction, and two guide rods are connected between the two lifting plates. The two guide parts are also provided with two second guide grooves arranged vertically, and the two guide rods pass through the two second guide grooves and the two slide grooves respectively. When the lifting plate moves up and down, the guide rod moves with it. Since one end of the swing arm is hinged on the support frame, the height of this end remains unchanged. During the up and down movement of the guide rod, the groove wall of the slide groove will be pushed along the top of the slide groove, causing the swing arm to swing up and down. The design of the guide rod and the guide groove provides a guiding function to ensure that the guide rod slides along the top of the slide groove during the up and down movement. This guiding function can make the movement of the fixing device more stable and controllable, and prevent the device from deviating or shaking during use.

[0011] In the above-mentioned wheel fixing device for loading and transporting passenger cars, an articulated shaft is connected between the two guide parts, and the articulated ends of the two swing arms are inserted into the gap between the two guide parts and articulated on the articulated shaft. The articulated shaft provides a relatively stable connection point, so that the swing arm can make limited rotational movement in the fixing device. This stability helps to maintain the stability of the fixing device and the uniform distribution of the clamping force, ensuring that the wheel will not loosen or shift during transportation.

[0012] In the above-mentioned wheel fixing device for loading and transporting passenger vehicles, the support frame also has a plate-shaped fixing portion, which is integrally formed at the lower part of the two guide portions and connects the two guide portions, and the lower end of the oil cylinder is fixed to the fixing portion. The fixing portion is connected between the two guide portions. This design can simplify the installation process of the device. By fixing the lower end of the oil cylinder to the fixing portion, the overall installation and adjustment of the fixing device can be achieved, making the installation process more convenient and efficient.

[0013] In the above-mentioned wheel fixing device for loading and transporting passenger cars, the support frame further has a sliding portion that is slidably connected to the base along the length direction of the clamp arm, and the sliding portion is integrally formed below the fixing portion. Through the sliding connection between the sliding portion and the base, this sliding adjustment performance enables the fixing device to adapt to passenger cars with different wheel spacings to meet different loading requirements.

[0014] In the above-mentioned wheel fixing device for loading and transporting passenger vehicles, the base has two symmetrically arranged receiving grooves, and when the two swing arms swing downward, the two clamping arms can be located in the receiving grooves. The design of the receiving grooves can effectively utilize the base space, and by storing the clamping arms in the receiving grooves, the overall size of the fixing device can be minimized, and more space can be left for other loaded items or equipment, making it more compact and efficient.

[0015] In the above-mentioned wheel fixing device for loading and transporting a passenger car, the top of the base has a concave arc-shaped bearing surface. The arc-shaped bearing surface can match the shape of the passenger car wheel, which helps to provide stable support and fixation, and maintain the safety and balance of the wheel.

[0016] Compared with the prior art, the advantages of the utility model are:

[0017] 1. The lifting plate and the swing arm are connected by a driving mechanism so that the entire swing arm can move upward and unfold stably. The support frame provides a good supporting foundation, reduces the shaking and swaying of the device during transportation, and improves stability.

[0018] 2. The clamping arm can also be retracted as the swing arm swings downward, so that the vehicle can drive in more conveniently, improving the convenience of using the device.

[0019] 3. The first guide groove forms a sliding guide for the lifting plate. When the lifting plate moves up and down, the two swing arms move synchronously, so that the clamping force is evenly applied to the wheel, providing a more stable fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS
