Description

Technical Field

[0001] The invention relates to the technical field of logistics transportation, and in particular to a universal wheel with a balancing mechanism for logistics equipment. Background Art

[0002] A swivel wheel is a so-called movable caster, and its structure allows for 360-degree horizontal rotation. Casters are a general term, including movable casters and fixed casters. Fixed casters have no rotating structure and cannot rotate horizontally but only vertically. These two types of casters are generally used in combination. For example, a trolley has two fixed wheels in the front and two movable swivel wheels in the back near the push handles. Casters, as an important component of many handling tools, are not only walking parts, but also have the function of shock absorption, especially in logistics places with uneven ground conditions. The shock absorption effect of casters plays a key role in the quality of handling operations and the noise of the working environment.

[0003] After searching, Chinese patent No. CN105417443A discloses a universal shock-absorbing balance wheel mechanism. Although it can rotate 360°, which improves the steering flexibility of the whole vehicle, it does not have a balancing mechanism, so that the balance wheel cannot balance the logistics equipment, especially when the logistics equipment is used on bumpy ground, the logistics equipment will vibrate violently, which not only reduces the safety of the transported goods, but also easily damages the logistics equipment, bringing about the problem of device defects. Summary of the invention

[0004] The purpose of the present invention is to solve the defects in the prior art and to propose a universal wheel for logistics equipment with a balancing mechanism.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A universal wheel for logistics equipment with a balancing mechanism comprises a wheel frame, one end of the wheel frame is rotatably connected to a roller, the other end of the wheel frame is rotatably connected to a swivel block, the top surface of the swivel block is fixedly connected to a fixed block, the top of the fixed block is provided with a support rod, the outer surface of the support rod is provided with a slide groove, and the support rod is provided with a cavity, the top surface of the fixed block is respectively fixedly connected to a telescopic rod and a push rod, the other end of the push rod is fixedly connected to a piston, the outer surface of the piston is fixedly connected to a sealing ring, the top outer surface of the telescopic rod is fixedly connected to a slider, the other end of the slider is fixedly connected to a moving ring, and the top surface of the moving ring is installed with an infrared rangefinder.

[0011] Furthermore, the electric valve 1 and the electric valve 2 are opened and closed synchronously, the output end of the infrared rangefinder is electrically connected to a controller, and the output end of the controller is electrically connected to the input ends of the electric valve 1, the electric valve 2 and the actuator cylinder respectively.

[0012] Furthermore, the electromagnetic fluid is composed of synthetic hydrocarbons and magnetic particles with a size of 0.1-1.0 μm, and the actuator cylinder pushes the fixed block and the wheel frame to move through the electromagnetic fluid, the piston and the push rod.

[0013] Furthermore, the fixed block, the push rod and the piston are all fixedly sleeved with a main conductor, one end of the main conductor is connected to an external power supply, the other end of the main conductor is fixedly connected to a coil, and the outer surface of the coil is in contact with a magnetic rod.

[0014] Furthermore, the magnetic rods are evenly distributed about the central axis of the coil, and the magnetic rods are connected to the piston through and fixedly connected.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention receives the roller oscillation signal through a controller and immediately starts an external power supply, so that the external power supply supplies power to the main conductor, so that the coil connected to the main conductor generates an induced magnetic field, and then the induced magnetic field is concentrated and magnetized into the electromagnetic fluid through the magnetic rod on the piston, so that the arrangement direction of particles in the electromagnetic fluid is changed, and the arrangement direction of the particles is perpendicular to the movement direction of the piston, thereby hindering the flow of the electromagnetic fluid in the cavity, thereby improving the damping coefficient, so that the movement of the piston and the push rod is buffered, and the shock absorbing effect of the roller and the wheel frame can be adjusted to avoid severe vibration of the logistics equipment on the universal wheel, so as to achieve the purpose of balancing the logistics equipment, which not only improves the safety of the transported objects, but also extends the service life of the logistics equipment.

[0017] 2. The present invention determines the universal wheel that needs to be adjusted and the lifting height through the controller, and then opens the electric valve 1 and the electric valve 2 respectively through the controller, and then starts the actuator cylinder, so that the reciprocating component in the actuator cylinder pushes the electromagnetic fluid downward, so that the electromagnetic fluid is further squeezed into the cavity in the support rod, so that the hydraulic pressure in the cavity increases, so that the electromagnetic fluid squeezes the top of the piston, and through the reaction force, the support rod rises relative to the push rod, and finally lifts a corner of the logistics equipment through the fixed plate on the support rod, so that the logistics equipment is rebalanced, further ensuring the balance of the logistics equipment and preventing the load from falling from the logistics equipment.

[0033] Specifically, in the process of balancing the logistics equipment with universal wheels, the controller determines the universal wheels that need to be adjusted and the lifting height based on the data of the infrared rangefinder 10 on the four corners of the logistics equipment, and then opens the electric valve 17 and the electric valve 2 21 respectively through the controller, and then starts the actuator cylinder 20, so that the reciprocating assembly in the actuator cylinder 20 pushes the electromagnetic fluid 16 downward, so that the electromagnetic fluid 16 is further squeezed into the cavity 15 in the support rod 6, so that the hydraulic pressure in the cavity 15 increases, so that the electromagnetic fluid 16 squeezes the top of the piston 13, and through the reaction force, the support rod 6 rises relative to the push rod 12, and finally lifts a corner of the logistics equipment through the fixed plate 26 on the support rod 6, so that the logistics equipment is rebalanced, further ensuring the balance of the logistics equipment and preventing the load from falling from the logistics equipment.
