Description

Technical Field

[0001] This invention belongs to the technical field of material handling equipment, and in particular relates to a plate-shaped object handling device and its usage method. Background Technology

[0002] In fields such as building construction, precast component processing, and large-scale panel warehousing and logistics, it is often necessary to handle and relocate large-sized plate-shaped objects over short distances. Due to the physical characteristics of these objects, which are typically large in area, thin in thickness, heavy in weight, and have a high center of gravity, they are extremely prone to tipping over or surface damage during handling.

[0003] Currently, on-site handling of such items mainly relies on manual labor in conjunction with simple handcarts or forklifts. However, existing handling methods have several objective drawbacks. First, simple handcarts lack dedicated vertical clamping and positioning structures, making it easy for plate-shaped objects to wobble, slip, or even tip over during transport due to road bumps or turns, posing significant safety hazards. Second, when loading and unloading objects, the upper support structure often creates spatial interference, preventing objects from being smoothly hoisted vertically or placed into the bottom positioning slot. This requires repeated manual adjustments to the object's posture, making the operation cumbersome and labor-intensive. Furthermore, existing handling tools are difficult to adapt to plates of different heights and thicknesses, exhibiting poor versatility. In narrow and complex construction site environments, the equipment's turning flexibility and parking stability are difficult to balance, resulting in overall low handling efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a plate-shaped object handling device and its usage method, which is particularly suitable for transporting large-sized plate-shaped objects in construction sites with limited space.

[0005] The technical solution adopted by this invention is as follows: Firstly, a plate-shaped object handling device is provided for transporting plate-shaped components, comprising:

[0006] The support base has a walking mechanism at its bottom;

[0007] A lower positioning seat is disposed on the bearing base, and the lower positioning seat has a receiving space for accommodating the bottom of the plate component;

[0008] The lower clamping assembly is disposed on the lower positioning seat and is used to apply a clamping force to the bottom of the plate member located in the receiving space;

[0009] A rotatable lifting support arm, the lower end of which is rotatably connected to one side of the lower positioning seat or the bearing base, and the length of the rotatable lifting support arm is adjustable;

[0010] A lateral extension arm is connected to the upper end of the rotatable lifting support arm;

[0011] An upper clamping assembly is disposed on the lateral extension arm;

[0012] The upper clamping assembly rotates relative to the bearing base with the rotatable lifting support arm to switch between a loading avoidance position and a clamping working position; in the clamping working position, the upper clamping assembly and the lower clamping assembly are arranged vertically opposite each other to jointly clamp and fix the plate component.

[0013] Furthermore, the walking mechanism includes at least two omnidirectional walking wheels disposed at the bottom front end of the support base, and at least two directional walking wheels disposed at the bottom rear end of the support base; the omnidirectional walking wheels and / or the directional walking wheels are lockable walking wheels with braking structures.

[0014] Furthermore, the lower positioning seat is a U-shaped positioning seat, and the lower clamping assembly includes a first threaded adjusting clamping member, which passes through the side wall of the lower positioning seat and extends its end into the receiving space to abut against the plate member.

[0015] Furthermore, the rotatable lifting support arm is a multi-stage nested telescopic rod, with a length locking assembly between adjacent nested rods; the lower end of the rotatable lifting support arm is connected to the lower positioning seat through a rotating hinge assembly, and the rotation axis of the rotating hinge assembly extends horizontally along the forward direction perpendicular to the bearing base.

[0016] Furthermore, the rotary hinge assembly also includes an angle positioning element for locking the position of the rotatable lifting support arm.

[0017] Furthermore, the upper clamping assembly includes a second threaded adjusting clamping member and a clamping pressure plate. The second threaded adjusting clamping member is disposed on the lateral extension arm, and the clamping pressure plate is arranged opposite to the second threaded adjusting clamping member to cooperate in clamping the upper part of the plate member.

[0018] Furthermore, in the clamping working position, the clamping action line of the first threaded adjusting clamping member and the clamping action line of the second threaded adjusting clamping member are located in the same vertical plane.

[0019] Secondly, a method for using a plate-shaped object handling device is provided, including the following steps:

[0020] Move the plate-shaped object handling device to the loading area and lock the walking mechanism;

[0021] Adjust the length of the rotatable lifting support arm to match the height of the plate component to be transported, and rotate the rotatable lifting support arm so that the upper clamping assembly rotates with the lateral extension arm to the loading clearance position, opening the upper opening of the lower positioning seat.

[0022] The plate-shaped component is vertically placed into the receiving space of the lower positioning seat, and the lower clamping assembly is adjusted to clamp the bottom of the plate-shaped component.

[0023] Rotate the rotatable lifting support arm in the opposite direction to reset the upper clamping assembly to the clamping working position, and adjust the upper clamping assembly so that it and the lower clamping assembly together vertically clamp and fix the plate component.

[0024] Unlock the walking mechanism, push the plate component transport device to transport the plate component to the target position, and after arrival, release the upper clamping assembly and the lower clamping assembly to remove the plate component.

[0025] The advantages and positive effects of this invention are as follows: by adopting the above technical solution, structural interference during loading and unloading is effectively eliminated, allowing plate-shaped objects to be smoothly placed or moved vertically, greatly reducing the difficulty of operation; through the coordinated cooperation of the upper and lower clamping components, stable vertical clamping of plate-shaped objects is achieved, significantly improving the anti-shaking ability and safety during handling; the structural layout is compact and reasonable, making it particularly suitable for material transfer operations in construction sites with limited space or in narrow passages.

[0030] The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. The technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative effort are within the scope of protection of the present disclosure.

[0031] like Figure 1 As shown, the present invention provides a plate-shaped object handling device, comprising:

[0032] The support base 1 has a walking mechanism 2 at its bottom. The support base 1 serves as the basic support platform for the entire device. Its material includes, but is not limited to, metal profiles (such as channel steel, square tube, and I-beam), high-strength engineering plastics, or composite materials. The walking mechanism 2 at the bottom includes at least three support wheels. The form of the walking mechanism 2 includes, but is not limited to, support wheels, tracks, air cushions, and slide rail slider structures to achieve spatial displacement of the device.

[0033] The lower positioning seat 3 is disposed on the support base 1. The lower positioning seat 3 has a receiving space for accommodating the bottom of the plate component 8. The receiving space includes at least a U-shaped groove, and may also include, but is not limited to, a V-shaped groove, an L-shaped corner groove, or a flat tray with side baffles, as long as it can limit the bottom of the plate component 8.

[0034] The lower clamping assembly 4 is disposed on the lower positioning seat 3 and is used to apply clamping force to the bottom of the plate member 8 located in the receiving space; the lower clamping assembly 4 includes, but is not limited to, a manual threaded clamping member, a cylinder push rod, a hydraulic cylinder, a cam clamping mechanism and an electric push rod.

[0035] The rotatable lifting support arm 5 has its lower end rotatably connected to one side of the lower positioning seat 3 or the bearing base 1. The length of the rotatable lifting support arm 5 is adjustable. The length adjustment mechanism of the rotatable lifting support arm 5 includes, but is not limited to, multi-stage sleeve nesting, scissor lifting structure, screw nut lifting mechanism or gear rack lifting mechanism. The rotation connection method of its lower end includes, but is not limited to, pin hinge, hinge connection, bearing connection and universal joint connection.

[0036] The lateral extension arm 6 is connected to the upper end of the rotatable lifting support arm 5; the lateral extension arm 6 includes, but is not limited to, straight profiles, curved arms, and polygonal arms.

[0037] The upper clamping assembly 7 is mounted on the lateral extension arm 6. The upper clamping assembly 7 includes, but is not limited to, threaded clamping parts and pressure plates, pneumatic grippers, electromagnetic chucks or vacuum chucks, as long as they can cooperate with the lower clamping assembly 4 to form an upper and lower clamping.

[0038] The upper clamping assembly 7 rotates relative to the bearing base 1 with the rotatable lifting support arm 6 to switch between the loading avoidance position and the clamping working position; in the clamping working position, the upper clamping assembly 7 and the lower clamping assembly 4 are arranged opposite each other to clamp and fix the plate component 8.

[0039] The above-mentioned design effectively eliminates structural interference during loading and unloading, allowing plate-shaped objects to be smoothly placed or removed vertically, significantly reducing operational difficulty. Through the coordinated operation of the upper and lower clamping components, stable vertical clamping of plate-shaped objects is achieved, significantly improving anti-sway capability and safety during handling. The compact and reasonable structural layout is particularly suitable for material transfer operations in space-constrained construction sites or narrow passages.

[0040] In one embodiment, the walking mechanism includes at least two omnidirectional wheels disposed at the bottom front end of the support base, and at least two directional wheels disposed at the bottom rear end of the support base; the omnidirectional wheels and / or directional wheels are lockable wheels with braking structures. The cooperation between the front omnidirectional wheels and the rear directional wheels gives the device excellent steering flexibility, enabling it to make flexible turns and fine adjustments in narrow spaces; the lockable structure ensures that the device remains absolutely still during loading, unloading, and clamping operations, preventing the risk of objects tipping over or people being pinched due to accidental slippage.

[0041] In one embodiment, the lower positioning seat is a U-shaped positioning seat, and the lower clamping assembly includes a first threaded adjustment clamping member, which is disposed on the side wall of the lower positioning seat and its end extends into the receiving space to abut against the plate-type member.

[0042] In one embodiment, the rotatable lifting support arm is a multi-level nested telescopic rod, and a length locking component is provided between two adjacent nested rods; the lower end of the rotatable lifting support arm is connected to the lower positioning seat through a rotary hinge component, and the rotation axis of the rotary hinge component extends horizontally along the forward direction perpendicular to the bearing base.

[0043] In one embodiment, the rotary hinge assembly further includes an angle positioning element for locking the position of the rotatable lifting support arm.

[0044] In one embodiment, the upper clamping assembly includes a second threaded adjusting clamping member and a clamping pressure plate. The second threaded adjusting clamping member is disposed on the lateral extension arm, and the clamping pressure plate is arranged opposite to the second threaded adjusting clamping member to cooperate in clamping the upper part of the plate-type component.

[0045] In one embodiment, in the clamping working position, the clamping action line of the first threaded adjusting clamping member and the clamping action line of the second threaded adjusting clamping member are located in the same vertical plane.

[0046] In one embodiment, a flexible abutment layer is laid on the bottom surface of the U-shaped groove of the lower positioning seat, the inner surface of the side wall, and the contact surface between the upper clamping pressure plate and clamping block and the plate component, all by means of bolt fixing or adhesive bonding. This flexible abutment layer is specifically a polyurethane elastic anti-slip pad with an anti-slip texture or a rubber cushioning coating, used to increase the coefficient of friction and prevent hard metal parts from scratching or crushing the surface of the plate-shaped object. Apart from welding, high-strength bolt fasteners are used to connect the various components of the support base at nodes requiring disassembly and maintenance.

[0047] like Figure 2 As shown, this embodiment provides a preferred implementation method and describes in detail the core mechanical structure of the plate-shaped object handling device.

[0048] The support base 1 adopts a frame structure welded from rectangular square tubes; the walking mechanism 2 adopts a four-wheel layout, with two polyurethane omnidirectional walking wheels with universal wheels installed at the front end and two directional rubber wheels installed at the rear end. All four wheels are equipped with foot-operated brake pads.

[0049] The lower positioning seat 3 is a U-shaped positioning seat made of thick steel plate bent and welded, with the opening facing upwards. The lower clamping assembly 4 adopts the first threaded adjustment clamping component, specifically a coarse-toothed screw with a handle at one end and a washer at the other end. The screw passes through the threaded hole on one side wall of the U-shaped positioning seat, and the end extends into the U-shaped groove. Rotating the handle can drive the threaded rod to feed linearly, causing the washer to move closer to or away from the plate.

[0050] The rotatable lifting support arm 5 is a multi-stage nested telescopic rod composed of three levels of square steel tubes. Each level of steel tube has multiple positioning holes on its side, and spring pins are inserted as length locking components. The lower end of the rotatable lifting support arm 5 is connected to the outer wall of the lower positioning seat 3 through a rotating hinge assembly with heavy-duty bearings. The axis of rotation is horizontal and perpendicular to the length direction of the base.

[0051] The lateral extension arm 6 uses a square tube of the same specifications as the rotatable lifting support arm 5 and is horizontally welded to the top of the rotatable lifting support arm 5. The upper clamping assembly 7 includes a second threaded adjusting clamping element (also a screw with a handle and washer) and a clamping pressure plate made of a rectangular steel plate. The screw passes through a threaded hole on the lateral extension arm, and the clamping pressure plate is connected to the bottom end of the screw via a bearing or ball joint structure to ensure that the pressure plate remains parallel and in contact with the object. In the clamping working position, the center lines of the upper screw and the lower screw are strictly aligned on the same vertical plane.

[0052] like Figure 3 As shown, in order to better utilize a plate-shaped object handling device, this application also proposes a method of using the plate-shaped object handling device, including the following steps:

[0053] S10. Move the plate-shaped object handling device to the loading area and lock the walking mechanism;

[0054] S20. Adjust the length of the rotatable lifting support arm to match the height of the plate component to be transported, and rotate the rotatable lifting support arm so that the upper clamping assembly rotates with the lateral extension arm to the loading clearance position, opening the upper opening of the lower positioning seat.

[0055] S30. Place the plate component vertically into the receiving space of the lower positioning seat, adjust the lower clamping assembly, and clamp the bottom of the plate component.

[0056] S40. Reverse rotation of the rotatable lifting support arm resets the upper clamping assembly to the clamping working position. Adjust the upper clamping assembly so that it, together with the lower clamping assembly, vertically clamps and fixes the plate component.

[0057] S50. Unlock the walking mechanism and push the plate component transport device to transport the plate component to the target position. After arrival, release the upper clamping assembly and the lower clamping assembly to remove the plate component.

[0058] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
