Description

Technical Field

[0001] This application relates to the field of lifting equipment technology, and in particular to a heavy-duty truck wheel hub lifting equipment. Background Technology

[0002] As an important component of trucks, heavy-duty truck wheel hubs bear the weight of the vehicle and transmit power. They are cylindrical metal parts that support the tires and are centrally mounted on the axle. They have a central hole inside for mounting components. Different vehicle models have different wheel hub sizes, and larger vehicles have larger wheel hubs.

[0003] Currently, wheel hubs are typically hoisted using nylon slings or steel cables. Operators simply tie the wheel hubs to the slings or cables, and then a crane lifts them. For wheel hubs lying flat, manual lifting or standing is required before tying them up, which is inconvenient. Improper handling during the process of turning a flat wheel hub into an upright position can also cause injury to operators, posing a safety hazard. Utility Model Content

[0004] To solve the aforementioned technical problems, this utility model provides a heavy-duty truck wheel hub lifting tool, addressing the issues of inconvenient lifting and potential safety hazards. The technical solution adopted by this utility model to solve these problems is as follows:

[0005] A heavy-duty truck wheel hub spreader includes:

[0006] Horizontal plate;

[0007] The booms are symmetrically arranged on both sides of the horizontal plate in a hinged structure.

[0008] A lifting plate used to drive the boom to rotate at the hinge point, the lifting plate being positioned above the horizontal plate;

[0009] The grippers, each corresponding to a specific boom, are fixedly installed at the bottom of the boom.

[0010] An inverted frustum is fixedly positioned on the lower end face of the center of a horizontal plate.

[0011] Furthermore, inclined grooves are symmetrically opened on both sides of the lifting plate, and bearings are installed in the inclined grooves. The bearings are rotatably connected to the boom. A slot connected to the lifting plate is opened on one side of the boom. The slot is equipped with a pin A and a locking nut in a fixed structure. The bearing is installed in the slot through pin A.

[0012] Furthermore, a connecting rod is fixedly installed on the upper surface of the horizontal plate in a vertical direction, and a groove is provided in the middle of the connecting rod for the sliding of the lifting plate.

[0013] Furthermore, the connecting rods on both sides of the groove are provided with sliding grooves, and a pin B is provided in the sliding groove in a sliding structure. The pin B is fixedly connected to the lifting plate.

[0014] Furthermore, hinge seats for hinged booms are symmetrically arranged on both sides of the upper surface of the horizontal plate in a fixed structure.

[0015] Furthermore, a suspension rod is fixedly installed at the top of the lifting platform, and a lifting ring is fixedly installed at the top of the suspension rod.

[0016] The beneficial effects of this utility model are: by setting an inverted truncated cone under the horizontal plate, precise centering is not required. The inverted truncated cone is used to align with the center hole of the wheel hub in the flat state during the descent, which reduces the steps of manually adjusting the lifting tool and saves manpower.

[0017] By setting up a lifting plate, boom, horizontal plate, grippers, and truncated cone, the wheel hub can be easily lifted and transported. The structure is simple in design and increases its practicality. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0023] A heavy-duty truck wheel hub lifting device includes: a horizontal plate 1; booms 4 are symmetrically arranged on both sides of the horizontal plate 1 in a hinged structure; a lifting plate 2 is provided on the upper part of the horizontal plate 1 for driving the booms 4 to rotate at the hinge point; grippers 5 are fixedly arranged on the lower part of the booms 4; and an inverted truncated cone 6 is fixedly arranged on the lower end face of the center of the horizontal plate 1. By setting the inverted truncated cone 6 under the horizontal plate 1, precise centering is not required. The inverted truncated cone 6 is used to align with the center hole of the wheel hub in the flat state during the descent, reducing the steps of manual adjustment of the lifting device and saving manpower. By setting the lifting plate 2, booms 4, horizontal plate 1, grippers 5 and truncated cone 6, the lifting of wheel hubs can be easily realized. The structure design is simple and increases the practicality of the structure.

[0024] It should be noted that inclined grooves 9 are symmetrically provided on both sides of the lifting plate 2, and bearings 10 are installed in the inclined grooves 9. The bearings 10 are rotatably connected to the boom 4. The inclined grooves 9 are provided to meet the vertical movement of the lifting plate 2 and the rotation of the boom 4 at the hinge point. A slot 41 connected to the lifting plate 2 is provided on one side of the boom 4. The slot 41 is provided with a pin A11 and a locking nut 12 in a fixed structure. The bearing 10 is installed in the slot 41 through the pin A11. The slot 41 facilitates the assembly of the boom 4 and the lifting plate 2.

[0025] It should be noted that a connecting rod 7 is fixedly installed on the upper surface of the horizontal plate 1 in a vertical direction, and a groove 8 is provided in the middle of the connecting rod 7 for the lifting plate 2 to slide; the groove 8 provides a sliding track for the lifting plate 2.

[0026] Furthermore, the connecting rods 7 on both sides of the groove 8 are provided with sliding grooves 15. A pin B16 is provided in the sliding groove 15 in a sliding structure. The pin B16 is fixedly connected to the lifting plate 2. The sliding groove 15 provides a sliding channel for the pin B16. The cooperation between the pin B16 and the sliding groove 15 ensures that the lifting plate 2 maintains linear movement when moving up and down, prevents lateral deviation, and ensures that the two booms 4 move in the same direction in the sliding groove 15.

[0027] It should be noted that hinge seats 13 for hinged boom 4 are symmetrically arranged on both sides of the upper end face of the horizontal plate 1 in a fixed structure; the top of the lifting plate 2 is provided with a lifting rod 3 in a fixed structure, and the top of the lifting rod 3 is provided with a lifting ring 14 in a fixed structure. This structure is used for attaching the crane hook.

[0028] The working principle and process of this utility model are as follows:

[0029] The lifting device is positioned above the center hole of the wheel hub. At this point, the device does not need to be perfectly aligned. The overhead crane slowly lowers the entire device, bringing the lower end of the inverted truncated cone 6 close to the center hole of the wheel hub. As the inverted truncated cone 6 gradually enters the center hole, its curved design causes it to slowly move towards the center of the hole upon contact with the sidewall, ensuring its lower end smoothly enters the center hole. As the device continues to lower, the operator places the two grippers 5 on the edge of the wheel hub, stopping the lowering once they are gripping the hub. The lifting device is then lifted upwards by the crane. At this time, the weight of the wheel hub and the upper pulling force provided by the crane work together to pull the lifting plate 2 to the upper position of the connecting rod 7 by the boom 3. At this time, the pin B16 is at the top position of the slide groove 15. The booms 4 on both sides slide down along the inclined groove 9 and rotate inward around the hinge point. The gripper 5 closes inward until it grips the edge of the wheel hub and stops sliding down. During this period, the horizontal plate 2 remains stationary. The entire lifting device is lifted up, and the lifting device and wheel hub are lifted together for hoisting.
