DETAILED DESCRIPTION Example 1 This embodiment provides a loading and unloading device for installation on a lifting device, such as Figure 1 As shown, the loading and unloading device includes a bearing mechanism and a supporting platform, the bearing mechanism includes a bearing component, and the bearing component is arranged on the supporting platform. In this embodiment, a walking wheel 1 is provided at the bottom of the bearing component, and the walking wheel 1 cooperates with the supporting platform, so that the bearing component can walk a certain distance along the supporting platform. Connecting arms are provided on both sides of the bearing component, and the connecting arms are telescopic structures, including a first connecting part and a second connecting part telescopically connected to the first connecting part. The first connecting part is connected to the bearing component, and the outer end of the second connecting part is vertically fixedly connected to one end of the fixed arm. This bionic embracing action structure is adopted to simulate the structure of human arms, so that the loading and unloading device can fix the material more reliably.

[0020] The bearing component and the supporting platform both adopt an L-shaped structure.

[0021] like Figure 2As shown, the support platform includes a bottom support portion and a backrest support portion vertically arranged at one end of the bottom support portion, and both the bottom support portion and the backrest support portion adopt a frame structure formed by welding a plurality of round tubes.

[0022] Specifically, the bottom support portion shown includes two first circular tubes 2 which are arranged in parallel and along the traveling direction of the bearing component. The first circular tube 2 is arranged at a set acute angle with the horizontal plane. The first circular tube 2 is welded and fixed to the top ends of multiple vertical circular tubes 3. The vertical circular tubes 3 are used to support the first circular tube 2. The first circular tube 2 is also welded and fixed to the top of a positioning circular tube 4. The axis of the positioning circular tube 4 is not parallel to the axis of the vertical circular tube 3, which plays a role in positioning and stabilizing support. One end of the first circular tube 2 is vertically welded to the second circular tube 5. The two second circular tubes 5 form a backrest support portion of the support platform. The second circular tube 5 is welded and fixed to one end of a diagonal support circular tube 6. The diagonal support circular tube 6 is used to support the second circular tube 5.

[0023] In this embodiment, the bottom support part and the backrest support part of the support platform both adopt a frame structure formed by welding multiple round tubes, which has good bending resistance and avoids the defects of needing to set stiffening ribs when two cross-section steels such as channel steels are spliced ​​in parallel. The round tube structure has a better appearance.

[0024] like Figure 3 As shown, the load-bearing component is used to support the goods. The load-bearing component also adopts an L-shaped structure, including a bottom frame and a backrest frame fixed to one end of the bottom support frame. The bottom frame and the backrest frame both adopt a frame structure welded from multiple square tubes to avoid the setting of stiffening ribs. The square tubes are used as backrest rods for better bending resistance.

[0025] In this embodiment, the bottom frame includes two longitudinal square tubes 7 arranged along the walking direction, the longitudinal square tubes 7 are parallel to the first circular tubes 2, and the two longitudinal square tubes 7 correspond to the two first circular tubes 2 respectively. The two ends and the middle of the bottom surface of the longitudinal square tube 7 are installed with walking wheels 1, and the walking wheels cooperate with the first circular tubes 2. In this embodiment, the wheel surface of the walking wheel 1 is an inner concave surface, which ensures the stability of the cooperation between the walking wheel 1 and the first circular tube 2. The first circular tube 2 serves as both a wheel support and a wheel guide. A plurality of transverse square tubes 8 are vertically welded and fixed between the two longitudinal square tubes 7 to form a bottom frame structure. One end of the longitudinal square tube 7 is vertically welded and fixed to the bottom end of the backrest frame composed of a rectangular frame 9. A plurality of transverse square tubes and vertical square tubes are arranged inside the rectangular frame as support.

[0026] The longitudinal square tube 7 is parallel to the first circular tube 2 and also forms a set acute angle with the horizontal plane. In this way, photovoltaic panels and other goods are placed at an acute angle to the vertical plane, supported by the bottom frame and leaning on the backrest frame, making the storage of goods convenient and stable.

[0027] In order to avoid a rigid collision between the backrest frame and the backrest support part when the backrest frame returns to its original position, the second circular tube 5 is provided with an elastic buffer component. Preferably, the elastic buffer component is a rubber block 10. The rubber block 10 is in contact with the backrest frame to avoid a rigid collision between the backrest frame and the second circular tube 5, thereby playing a role of shockproof buffering.

[0028] like Figure 4-Figure 5 As shown, connecting arms are connected to both sides of the backrest frame. The connecting arms adopt a telescopic structure, including a first connecting part and a second connecting part telescopically connected to the first connecting part. The outer end of the second connecting part is vertically welded and fixed with a fixed arm.

[0029] In this embodiment, Figure 6-Figure 7 As shown, the first connection portion includes two parallel connecting square tubes 11, and two vertical square tubes 12 are vertically welded and fixed between the two connecting square tubes 11 to form a rectangular frame structure.

[0030] Two connecting lugs 13 are provided at the inner end of the connecting square tube 11. The connecting lugs 13 extend between the two fixed lugs 14 and are rotatably connected to the fixed lugs through a rotating shaft. The fixed lugs 14 are fixed to the outside of the backrest frame. In this embodiment, the rotating shaft is a bolt. The head of the bolt is pressed on the outer side of the fixed lug 14 on one side. The bolt rod passes through the two fixed lugs 14 and the connecting lug 13 and is threadedly connected with a nut. The nut is pressed on the outer side of the fixed lug 14 on the other side. The two fixed lugs 14 press the two connecting lugs 13, thereby realizing the locking and fixing of the first connecting part with the backrest frame. Loosening the nut can realize the rotation of the first connecting part. The nut serves as the fourth locking mechanism between the connecting arm and the backrest frame.

[0031] The distance between the two connecting square tubes 11 of the first connecting part on one side of the backrest frame is greater than the distance between the two connecting square tubes 11 on the other side, so that when the two connecting arms are rotated and folded, there will be no movement interference between the two connecting arms and the fixed arm.

[0032] The second connection part is telescopically connected to the first connection part and a first locking mechanism is disposed between the second connection part and the first connection part.

[0033] In this embodiment, the second connecting portion is also made of two telescopic square tubes 15, each telescopic square tube 15 is telescopically connected to the corresponding connecting square tube 11, and two first sliders 16 are provided on the connecting square tube 11. The telescopic square tube 15 passes through the first slider 16 and is slidably connected to the first slider 16.

[0034] Specifically, the first slider 16 includes a rectangular tube, and the four inner sides of the rectangular tube are provided with contact blocks, the contact blocks are in contact with the telescopic square tube 15 and are slidably connected to the telescopic square tube 15, wherein the tube wall located above the rectangular tube is provided with an opening, and correspondingly, the contact block on the inner side of the tube wall also forms an opening, and a pressure plate 17 is movably arranged in the opening. Specifically, two contact blocks 18 are provided on the inner side of the tube wall with the opening by bolts, and an opening is formed between the two contact blocks 18, and a contact block 2 19 is provided on the inner side of the tube wall on the opposite side of the tube wall by bolts, and contact blocks 3 20 are provided on the other two opposite inner sides of the tube wall by bolts. In this embodiment, the area of ​​the opening is larger than the area of ​​the pressure plate 17, and the pressure plate 17 can be placed in the opening to realize the movable setting, and the pressure plate 1 One side of 7 contacts with the telescopic square tube 15, and the other side contacts with the first cam 21. The first cam 21 is arranged on the cam sleeve, and the cam sleeve is rotatably connected with the camshaft. The camshaft adopts a bolt, and the cam sleeve is sleeved on the outer periphery of the rod of the bolt, and its two ends are respectively in contact with two ear plates fixed to the first slider 16. The bolt rod passes through the two ear plates and is threadedly connected by a locking nut. The two ear plates constitute a cam seat, and the head of the bolt is pressed against the outer side surface of the ear plate on one side, and the nut is pressed against the outer side surface of the ear plate on the other side. The ear plates on both sides clamp the cam sleeve, thereby realizing the locking and fixing of the first cam. Loosen the nut, the two ear plates loosen the cam sleeve, and the first cam can rotate freely. The cam sleeve is connected to one end of the shift rod 22, which is convenient for the staff to rotate the first cam 21.

[0035] The first cam 21 rotates to switch the state of the pressing plate 17 pressing and releasing the telescopic square tube 15 , thereby switching the state of the telescopic square tube 15 and the connecting square tube 11 between locking and releasing.

[0036] The first locking mechanism is arranged in this way to facilitate operation by staff. It can be understood that the first locking mechanism can adopt a locking bolt threadedly connected to the first slider, and technical personnel in this field can arrange it according to actual needs.

[0037] like Figure 8-Figure 9 As shown, the fixed arm includes two fixed rods 23 arranged in parallel, the plane where the axes of the two fixed rods 23 are located is perpendicular to the bottom frame, the fixed rods 23 are arranged along the extension direction of the entire fixed arm, and the fixed rods 23 are also made of square tubes. One end of the fixed rod 23 is vertically welded and fixed to the corresponding telescopic square tube 15, and a square tube 24 is vertically welded and fixed between the ends of the two fixed rods 23 connected to the telescopic square tube 15, and a connecting rod 25 is fixed between the other ends. A connecting piece 26 is also provided between the two fixed rods 23 to form a spatial truss structure. The fixed arm adopts a spatial truss structure composed of multiple rods such as fixed rods, square tubes, and connecting rods. Compared with the traditional single-rod bidirectional cantilever structure, the entire fixed arm has better anti-bending and anti-torsion effects.

[0038] like Figure 10-11 As shown, the connecting member 26 is made of a circular tube, and both ends of the connecting member are slidably connected to the two fixing rods 23 respectively, and can move along the axial direction of the fixing rods 23.

[0039] A second locking mechanism is provided between the end of the connecting member 26 and the fixing rod 23 , and the connecting member and the fixing rod can be locked and fixed by the second locking mechanism.

[0040] In this embodiment, the structure of the second locking mechanism is the same as that of the first locking mechanism, and also includes a second slider 27. The second slider 27 is fixedly connected to the connecting member 26. The fixing rod 23 passes through the second slider 27 and is slidably connected to the second slider 27. The second slider 27 has the same structure as the first slider 16, and also includes a rectangular tube. The inner sides of the four tube walls of the rectangular tube are provided with contact blocks. The contact blocks are in contact with the fixing rod 23 and are slidably connected to the fixing rod 23. The outer tube wall of the rectangular tube is provided with an opening, and the contact block on the inner side is also provided with an opening. A pressing plate 17 is movably provided at the opening. One side of the pressing plate 17 is in contact with the fixing rod 23, and the other side is in contact with the second cam 28. The second cam 28 is rotatably connected to the cam seat 29 fixed to the second slider through the cam sleeve 31. The connection method of the second cam 28 and the cam seat 29 is the same as the connection method of the first cam 21 and the cam seat, which is repeated here.

[0041] It is understandable that the second locking mechanism may also be a second locking bolt threadedly connected to the second sliding block 27 .

[0042] The connecting piece is provided with a stopper, which is used to contact the front side of the goods to prevent the goods from tipping forward during transportation.

[0043] In this embodiment, the stopper is a rubber ring 30 which is sleeved and fixed on the outer periphery of a mounting rod 32 . The mounting rod 32 is vertically fixed on a sleeve 33 . The sleeve 33 is sleeved on the outer periphery of the connecting member 26 and is rotatably connected to the connecting member 26 .

[0044] The bottom end of the sleeve 33 is provided with two notches, which are set 180 degrees apart. The sleeve is clamped on the fixing member through the notches. The fixing member adopts a fixing tube 34, which is vertically fixed to the connecting member 26, and the axis of the fixing tube 34 is parallel to the extension direction of the fixing arm.

[0045] When it is necessary to put goods on the load-bearing component, the sleeve 33 can be lifted, the notch and the fixing tube 34 are separated, the sleeve is rotated 180°, the notch is clamped on the fixing tube 34 again, and the rubber ring 30 is rotated to the outside of the space between the two fixing arms. At this time, the goods can be delivered. After the goods are delivered, the sleeve 33 is lifted, and the notch is clamped on the fixing tube 34 again after the sleeve is rotated 180°. At this time, the rubber ring 30 is located in the space between the two fixing arms, and the connecting member 26 slides along the fixing rod 23 until the rubber ring 30 contacts the front side of the goods, and then is locked by the second locking mechanism.

[0046] The structures of the connecting arms and the fixed arms on both sides of the backrest frame are the same and will not be repeated here.

[0047] The connecting arm can be retracted and the connecting piece can slide along the fixed arm, which meets the fixing requirements of goods of different sizes and improves the applicability of the entire loading and unloading device.

[0048] In this embodiment, Fig.12 As shown, since the first connecting portion is rotatably connected to the backrest frame, the two connecting arms can be rotated 90° to be perpendicular to the backrest frame, so that the connecting arms and the fixed arms can be folded and stowed, reducing the occupied volume and facilitating storage. At the same time, it can also avoid the loading and unloading device from colliding with the lifting equipment itself when the lifting equipment moves.

[0049] Furthermore, in order to limit the expansion of the connecting arm, a limiting beam 35 is provided on the back of the side portion of the backrest frame. The limiting beam 35 is made of a square tube and can contact the first connecting portion, thereby limiting the rotation of the first connecting portion.

[0050] In this embodiment, since the first connecting portion includes two connecting square tubes 11 , two limiting beams 35 are provided, and the two limiting beams 35 correspond to the two connecting square tubes 11 respectively.

[0051] Since the load-bearing component can move along the supporting platform through the walking wheels, in order to ensure the stability of the load-bearing component during transportation, a third locking mechanism is provided between the backrest frame of the load-bearing component and the backrest supporting portion of the supporting platform. In this embodiment, the third locking mechanism includes a plurality of locking ear plates fixed to the bottom surface of the limiting beam 35 below, and a locking pin passes through the plurality of locking ear plates. A locking bolt passes through the second circular tube 5, and a nut is threadedly connected to the locking bolt. The rod of the locking bolt passes through two locking plates 36, and one end of the locking plate 36 is rotatably connected to the rod of the locking bolt. The two locking plates 36 are respectively located on both sides of the second circular tube 5, and the other end of the locking plate 36 is provided with a through hole for the locking pin to pass through. The locking plate 36 is rotated so that the through hole of the locking plate 36 corresponds to the locking pin, and the locking pin is moved so that the locking pin passes through all the locking ear plates and the locking plate 36, thereby realizing the connection between the backrest frame and the backrest supporting portion.

[0052] Furthermore, the locking pin is provided with an anti-drop plate, which is located between the locking ear plates to prevent the locking pin from falling off the locking ear plates.

[0053] When the loading and unloading device of this embodiment is working, Fig.13 As shown, the third locking mechanism is loosened, the load-bearing component is pushed out a certain distance, and then the load-bearing component is loaded by a loading device such as a forklift. After loading is completed, the rubber ring is rotated to the space between the two fixed arms, and then the connecting piece is moved so that the rubber ring contacts the front side of goods such as the photovoltaic panel box 37, and the second locking mechanism is locked to prevent the goods from tipping forward during transportation. The load-bearing component is then returned to the initial position, and the load-bearing component and the support platform are locked by the third locking mechanism. At this time, the goods can be transported.

[0054] The loading is carried out after the bearing component is pushed out to prevent collision and interference between the loading equipment and the loading and unloading devices.

[0055] When the material is a photovoltaic panel, the photovoltaic panel is grabbed at a sideways angle, which avoids the use of a complicated turning device and avoids the damage of the photovoltaic panel due to self-weight squeezing.

[0056] The loading and unloading device of this embodiment is mainly used in the laying of photovoltaic panels in the photovoltaic field and other lifting machinery fields to carry and fix corresponding materials so that the lifting equipment can transport and store materials in an orderly, efficient and safe manner during production, installation, testing, logistics and other processes.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
