Description

Railway vehicle wheel lifting appliance

Technical Field

The utility model relates to the technical field of railway equipment, in particular to a wheel lifting appliance for a railway vehicle.

Background

Railway traffic is an important transportation tool for people to go out, and in the running process of railway vehicles, the requirements on wheels for the railway vehicles are very strict in the production, processing, press fitting and use processes of the wheels due to high safety performance requirements of the wheels. In the railway vehicle production process, in order to satisfy the clamping requirement of the machine tool, realize the normal circulation of wheel in the process, prevent that the work piece from appearing the bruise etc, need dispose corresponding hoist, and traditional hoist only utilizes the transport of manpower, both the time of wasting is saved and the cost is increased, current hoist is closed and the closed dynamics of claw through the gravity control card of tire at long-term handling wheel process, this in-process takes place the deformation easily, the connected mode between the part parts is uncoordinated, it is less with the area of contact of being hung the part, often make the work piece surface appear the quality problem, also have the potential safety hazard.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks or disadvantages, it is an object of the present invention to provide a railway vehicle wheel hanger.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

a railway vehicle wheel lifting appliance comprises a lifting base, wherein an installation seat is installed on the lifting base, a hydraulic cylinder is installed in the installation seat, a sliding rod is installed at the movable end of the hydraulic cylinder, a plurality of grabbing arms are evenly installed at the bottom of the lifting base, a connecting rod is installed on the sliding rod, and the other end of the connecting rod is connected with the grabbing arms; and a lifting ring for lifting is further installed at the top of the installation seat.

Three grabbing arms are uniformly arranged at the bottom of the hoisting base.

The grabbing arm is provided with a clamping groove clamped with the tire.

The connecting rod is hinged with the sliding rod and the grabbing arm.

And the grabbing end of the grabbing arm is provided with a protective layer.

The protective layer is a silica gel layer or a rubber layer.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model provides a railway vehicle wheel lifting appliance, which can control the opening and closing of a grabbing arm through a power source of a hydraulic cylinder, so as to stably grab a railway vehicle wheel, avoid falling off in the lifting process and ensure the safety of the whole carrying process.

FIG. 2 is a schematic view of the construction of the wheel hanger gripping arm of the railway vehicle of the present invention;

fig. 3 is a top plan view of the railway vehicle wheel hanger of the present invention.

In the figure, 1, a base is hoisted; 2, a hydraulic cylinder; 3-a grasping arm; 4-a connecting rod; 5, a sliding rod; 6, mounting seats; 7-vehicle wheels; 8, hanging rings; 31-card slot.

Detailed Description

The present invention will now be described in detail with reference to the drawings, wherein the described embodiments are only some, but not all embodiments of the utility model. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, belong to the scope of the present invention.

As shown in fig. 1-3, the utility model provides a railway vehicle wheel crane, which comprises a hoisting base 1, wherein an installation seat 6 is installed on the hoisting base 1, a hydraulic cylinder 2 is installed in the installation seat 6, a sliding rod 5 is installed at the movable end of the hydraulic cylinder 2, a plurality of grabbing arms 3 are uniformly installed at the bottom of the hoisting base 1, a connecting rod 4 is installed on the sliding rod 5, and the other end of the connecting rod 4 is connected with the grabbing arms 3; and a lifting ring 8 for lifting is further installed at the top of the installation seat 6.

Preferably, the bottom of the hoisting base 1 is uniformly provided with three gripping arms 3, and the three gripping arms 3 are distributed at the outer edge of the hoisting base 1 at an angle of 120 degrees, and it should be said that the hoisting base 1 in the utility model is of a circular structure.

Preferably, the gripping arm 3 is provided with a locking groove 31 for engaging with a tire. The clamping groove 31 is positioned in the middle of the grabbing arm 3 and is clamped with the boss on the outer edge of the tire.

In the utility model, the connecting rod 4 is hinged with the sliding rod 5 and the grabbing arm 3, so that the grabbing arm 3 can be smoothly opened and closed under the pushing of the hydraulic cylinder 2 by the whole grabbing arm 3. The grabbing arm 3 is provided with a reinforcing rib, so that the strength and the force of the grabbing arm 3 are ensured.

In addition, in the utility model, the grabbing end of the grabbing arm 3 is provided with a protective layer, specifically, the protective layer is a silica gel layer or a rubber layer, so that the tire can fall off in the grabbing process, and on the other hand, some damage to the tire in the hoisting process can be ensured, and the loss is reduced.

The gravity sensor is arranged at the end part of the grabbing arm 3, so that whether the contact of the vehicle tire is good or not can be detected, whether the clamping of the vehicle tire and the grabbing arm 3 is safe and in place or not is guaranteed, and accidents in the hoisting process are avoided.

The working process of the utility model is as follows:

when the vehicle tire is lifted, the lifting appliance is installed on lifting equipment, the lifting equipment is used for lowering the device to a proper height, then the hydraulic cylinder 2 is used for pushing the grabbing arm 3 to be opened, after the device continues to be lowered, the grabbing arm 3 is moved to the wheel 7 and then continues to be lowered, when the bottom of the grabbing arm 3 is clamped with the wheel 7, the moving end of the hydraulic cylinder 2 is contracted, the sliding rod 5 is driven to move upwards, the connecting rod 4 is driven to contract, and finally the grabbing arm 3 is pulled to gather together to clamp the vehicle tire. When the lifting device lifts the lifting appliance to a specified position, the moving end of the hydraulic cylinder 2 pushes the sliding rod 5 to move downwards, so that the connecting rod 4 is driven to push the grabbing arm 3 to be opened, tires are put down, and lifting is completed.

It will be appreciated by those skilled in the art that the above embodiments are merely preferred embodiments of the utility model, and thus, modifications and variations may be made in the utility model by those skilled in the art, which will embody the principles of the utility model and achieve the objects and objectives of the utility model while remaining within the scope of the utility model.
