Description

Technical Field

[0001] This invention relates to the field of loading and unloading equipment technology, and specifically to a stone machinery device that facilitates unloading operations. Background Technology

[0002] In garden construction, rockery landscape decoration using stone materials is quite common. In garden construction, stone materials, as raw materials for building stone landscapes, need to be loaded, unloaded, and transported to the construction site.

[0003] Existing mechanical devices for loading and unloading stone mostly use hoisting equipment connected to ropes binding the stone; or hoisting equipment connected to clamping arms that hold the stone in place. The stone is then transported to the target location by the hoisting equipment, and the loading and unloading of the stone is achieved by untying the ropes or loosening the clamping arms.

[0004] Stone used in landscaping, such as for decorative garden paths and artificial rock formations, is often irregular in shape and size. Due to its irregular shape and fragile edges, it is prone to breakage or chipping during loading and unloading. Current technologies, whether using ropes to bind the stone or clamping arms, suffer from unstable gripping of irregular stones due to the varying shapes and sizes of their edges and corners, resulting in a risk of the stone slipping. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems in the prior art and provide a stone processing machinery device that facilitates unloading operations.

[0006] This invention provides a stone processing machinery device for easy unloading operations, comprising: a gripping assembly and a follower clamping assembly. The gripping assembly includes at least three gripping arms, and the follower clamping assembly is correspondingly configured at the gripping ends of each gripping arm. The follower clamping assembly includes multiple levels of follower clamping units, and each level of the follower clamping unit includes:

[0007] The first semicircular body has at least one arc-shaped groove on its side closest to the stone; the second semicircular body is adapted to the arc-shaped groove and is embedded in each of the arc-shaped grooves in a corresponding manner, and the second semicircular body slides in conjunction with the arc-shaped groove.

[0008] The number of stages of the follow-up clamping unit increases sequentially from the gripping end of the gripping arm toward the side closer to the stone. The first semicircle of the first-stage follow-up clamping unit is fixed to the gripping end of the gripping arm, and the second semicircle of each stage of the follow-up clamping unit serves as the first semicircle of the next stage of the follow-up clamping unit, thus forming a multi-stage follow-up clamping structure. This structure is used to make the end of the gripping arm contact the irregular surface of the stone through multi-stage sliding adjustment when each gripping arm approaches the stone.

[0009] The upper middle part of the gripping arm is provided with a clamping component, which is used to limit the swaying of the upper part of the stone. The clamping component includes a clamping arm, a slider, and a hinge rod. The slider is connected to one end of the clamping arm, and the other end of the clamping arm is used to clamp the stone. One end of the hinge rod is hinged to the slider, and the other end is hinged to the top of the adjacent gripping arm. The inner side of the gripping arm is provided with a groove adapted to the slider. The groove extends downward along the arm length to near the middle of the gripping arm and is located above the middle. When the clamping arm is clamped against the stone, the slider is located at the lowest end of the groove, so that after the clamping arm is subjected to pressure, the slider moves upward along the groove, thereby providing an upward supporting force to the end of the gripping arm, so that the gripping arm moves closer to the stone.

[0010] As a preferred embodiment, the inner surface of the arc-shaped groove is provided with an arc-shaped sliding groove, and the outer surface of the second semicircle is provided with an arc-shaped sliding rail, with the arc-shaped sliding groove slidingly engaging with the second semicircle. When clamping the stone, the stone surface contacts the second semicircle close to the stone. Since the stone surface is irregular and the clamping force points are different, the sliding engagement allows the unforced portion of the second semicircle to evenly bear the gripping force required by the stone, increases the gripping area, enhances the contact force, and achieves stable gripping.

[0011] As a preferred embodiment, three second semicircular bodies, located near the final stage of the stone, are staggered on the clamping surface of the first semicircular body. During the clamping process, the first and second semicircular bodies of each clamping unit are staggered and compressed to share the clamping force, thereby improving the overall stability of the follow-up clamping unit in the clamping state.

[0012] As a preferred embodiment, the inner surface of the second semicircle closest to the stone is provided with a flexible layer. The flexible layer structure fits the inner surface of the semicircle, preventing sliding breakage between the rigid joints when the arc-shaped slide rail and the arc-shaped slide groove slide together, and also improving the stability of the device.

[0013] As a preferred embodiment, the outer surface of the second semicircle closest to the stone is provided with a protruding buffer pad. This increases the friction between the outer surface of the second semicircle and the stone, further enhancing the device's stable grip on the stone.

[0014] As a preferred option, the multi-stage follow-up clamping unit is a three-stage follow-up clamping unit used for loading and unloading garden landscape stones. Considering factors such as material cost, stone type, shape, and volume, the three-stage follow-up clamping unit is the optimal design.

[0015] As a preferred embodiment, both the first semicircular body and the first semicircular body are made of rigid materials. Since garden landscape stones come in various types, rigid materials are suitable for the loading, unloading, and clamping of such stones due to their hardness, and the cost is reasonable and economical.

[0016] As a preferred embodiment, the outer arm of the gripping arm is provided with a pulley line track, and a pulley line is threaded through the pulley line track. One end of the pulley line is fixedly connected to a first semicircular body close to the stone. When clamping the stone, the force of lifting the stone can be converted into a clamping force close to the stone through the pulley line fixedly connected to the first semicircular body.

[0017] As a preferred embodiment, the sides of the first semicircular bodies near the stone protrude beyond the sides of the first semicircular body near the stone. This avoids the situation where, during clamping, one side of the semicircular body slides into the semicircular arc due to the force distribution on both sides, reducing the force-bearing area and lowering the force-bearing direction.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention provides a stone handling machinery device that facilitates unloading operations. It features multiple gripping arms that work together to clamp the stone. Each gripping arm has a gripping structure with a follow-up clamping component at its end, enabling the loading and unloading of irregular stones. The follow-up clamping component consists of multiple levels of follow-up clamping units. Each level of the follow-up clamping unit is composed of two mutually sliding semicircular bodies, allowing for relative sliding. This allows the follow-up clamping component to act on the stone contact surface, while each semicircular body within each clamping unit quickly adheres to the stone surface under the influence of the applied force and the weight of the stone itself. Because the stones vary in size and regularity, the outer surface of each semicircular body in contact with the stone surface, under the action of the follow-up clamping component, ensures maximum contact and uniform force application to the stone itself. This also enhances the adhesion between the follow-up clamping component and the irregular stone surface, resulting in a stable gripping effect.

[0020] This invention achieves multi-point clamping through multiple gripping arms and multiple second semicircles. The multiple second semicircles, through multi-level adjustment by a multi-stage follow-up clamping unit, can maximize contact with the irregular edges of the stone and achieve stable clamping. At the same time, multi-point clamping can disperse the local force at each clamping point, avoiding the problem of edge breakage and damage to the stone due to excessive local force during lifting caused by a limited number of clamping points and reduced contact area with the stone when encountering irregular stone surfaces.

[0021] The upper middle part of the gripping arm of the present invention is provided with a clamping component. When the follow-up clamping component clamps the stone, the clamping arm of the clamping component clamps against the stone, and the slider is located at the lowest end of the slide groove. After the clamping part is subjected to pressure, the slider moves upward along the slide groove, thereby giving the end of the gripping arm an upward supporting force, so that the gripping arm moves towards the side closer to the stone, and achieves the purpose of stable gripping.

Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0031] This embodiment discloses a stone processing machinery device for easy unloading operations, including a gripping component 1 and a follower clamping component 2. The gripping component 1 includes at least three gripping arms 11, and the follower clamping component 2 is correspondingly arranged at the gripping end of each gripping arm 11. The follower clamping component 2 includes multiple levels of follower clamping units, and each level of the follower clamping unit includes:

[0032] The first semicircular body 21 has at least one arc-shaped groove 211 on its side near the stone.

[0033] The second semicircular body 22 is adapted to the arc-shaped groove 211 and is embedded in each of the arc-shaped grooves 211 in a corresponding manner. The second semicircular body 22 and the arc-shaped groove 211 are in sliding fit.

[0034] The number of stages of the follow-up clamping unit 3 increases sequentially from the gripping end of the gripping arm 11 toward the side closer to the stone. The first semicircular body 21 of the first-stage follow-up clamping unit is fixed to the gripping end of the gripping arm 11, and the second semicircular body 22 of each stage of the follow-up clamping unit serves as the first semicircular body 21 of the next stage of the follow-up clamping unit, thereby forming a multi-stage follow-up clamping structure. This structure is used to make the end of the gripping arm 11 contact the irregular surface of the stone through multi-stage sliding adjustment when each gripping arm 11 approaches the stone.

[0035] like Figure 1As shown, the stone handling machinery device in this embodiment, which facilitates unloading operations, includes a gripping component 1 and a follow-up clamping component 2. The gripping component 1 in this embodiment is a conventional gripping component in the prior art, such as a four-corner gripper. The specific structure includes four gripping arms 11, which are connected to a lifting component via hinges 4. The lifting component can be a crane or a hydraulic lifting device, etc. When loading and unloading stone, the fixed pulley 3 connected below the hinges 4 can change the direction of the lifting component's pulling force. The lifting force of the lifting component is transmitted to the gripping arms connected to each other through the hinges 4, and part of the force is converted into a clamping force acting on the stone, realizing the mutual clamping of the gripping arms 11 and acting on the stone itself to perform the gripping action.

[0036] The clamping component in this embodiment, such as Figure 5 The diagram shows the structure of the clamping component 6 in this embodiment. The clamping component 6 includes a clamping arm 61, a slider 62, and a hinge rod 63. The slider 62 is connected to one end of the clamping arm 61, and the other end of the clamping arm 61 is used to clamp the stone. One end of the hinge rod 63 is hinged to the slider 62, and the other end is hinged to the top of the adjacent gripping arm 11. The gripping arm 11 has a groove 111 adapted to the slider 62 on its inner side. The groove 111 extends downward along the arm length of the gripping arm 11 to the upper middle part of the gripping arm 11. When the gripping arm 11 grips the component, the slider 62 is located at the lowest end of the groove 111 when the clamping arm 61 is clamped to the stone. This allows the slider 62 to move upward along the groove 111 after the clamping arm 61 is subjected to pressure, thereby providing an upward supporting force to the end of the gripping arm 11, so that the gripping arm 11 moves closer to the stone.

[0037] like Figure 2 As shown, in this embodiment, the stone machinery device for easy unloading operation has a gripping arm 11, a hinge 4 connected to the lifting assembly, and a hinge 4 hinged to the upper connection port 52 of the corresponding gripping arm 11. The lifting assembly is used to apply an upward lifting force. During the lifting process, the gripping assembly 1 is subjected to force. The four gripping arms 11 apply a central force towards the stone in a hinged manner, acting on the stone itself to perform a gripping action.

[0038] like Figure 3 As shown, a structural schematic diagram of the follower clamping assembly 2 in this embodiment is disclosed. The follower clamping assembly 2 in this embodiment includes multiple levels of follower clamping units. Each level of follower clamping unit is assembled by a sliding connection. When the gripping assembly 1 drives the gripping arm 11 to perform a gripping action, the clamping unit at the very end of the follower clamping assembly 2 is subjected to force and contacts the stone surface. Due to the semi-circular device on the follower clamping unit, it has a high degree of freedom. When it contacts the stone, each clamping unit is squeezed and subjected to force, and the force is uniform. It contacts the stone surface to the maximum extent, making its surface adhesion stronger, thereby achieving a stable gripping effect.

[0039] like Figure 4 As shown, the inner surface of the arc-shaped groove 211 is provided with an arc-shaped sliding groove 212, and the outer surface of the second semicircular body 22 is provided with an arc-shaped sliding rail 213. The arc-shaped sliding groove 212 and the arc-shaped sliding groove 212 are slidably engaged. When clamping the stone, the stone surface comes into contact with the second semicircular body 22 close to the stone. The stone surface is irregular, and the clamping force points are different. The sliding engagement allows the unforced portion of the second semicircular body 22 to evenly bear the gripping force required by the stone, and increases the gripping area, enhances the contact force, and achieves stable gripping.

[0040] Using the above-described technical solution of this embodiment, when loading and unloading irregular stones, a crane or hydraulic lifting equipment is used to load, unload, and lift the stones. The hinge 4 above the device is hinged to the lifting assembly. The fixed pulley 3 connected below the hinge 4 is fixed to the end of the gripping arm 11 through the pulley line. The gripping action is performed simultaneously. The four gripping arms 11 are connected to the hinge. The lifting force of the lifting assembly is transmitted to the respective connected gripping arms 11. Part of the lifting force changes direction under the action of the fixed pulley, transforming into a clamping force close to the stone for clamping. At the same time, when the clamping arm is pressed against the stone, the slider is located at the lowest end of the slide groove, so that after the clamping arm is subjected to pressure, the slider moves upward along the slide groove, thereby providing an upward supporting force to the end of the gripping arm, so that the gripping arm moves towards the side closer to the stone. At the same time, the gripping arm is connected to the lower 11. After the follower clamping assembly 2 is subjected to clamping force, the follower clamping units at each level, which are connected by a sliding connection, begin to bear force. The clamping unit at the very end of the follower clamping assembly 2 contacts the stone surface under force. Due to the high degree of freedom of the semi-circular device on the follower clamping unit, when it contacts the stone, each clamping unit is squeezed and subjected to force evenly, and the maximum range of contact with the stone surface is achieved. Furthermore, an arc-shaped slide rail 213 is provided on the outer surface of the second semi-circular body 22, and the arc-shaped slide groove 212 slides in cooperation with the arc-shaped slide groove 212. When clamping the stone, the stone surface contacts the second semi-circular body 22 that is close to the stone. Since the stone surface is irregular and the clamping force points are different, the sliding cooperation allows the part of the second semi-circular body 22 that is not under force to evenly bear the gripping force required by the stone, and increases the gripping area, enhances the contact force, and achieves the effect of stable gripping.

[0041] Meanwhile, this embodiment achieves multi-point clamping through multiple gripping arms and multiple second semicircles. The multiple second semicircles, through multi-level adjustment by the multi-level follow-up clamping unit, can make maximum contact with the irregular edges of the stone and achieve stable clamping. At the same time, multi-point clamping can disperse the local force at each clamping point, avoiding the problem of edge breakage and damage to the stone due to excessive local force during the lifting process caused by the limited number of clamping points and the reduced contact area between the limited clamping points and the stone when encountering irregular stone surfaces.

[0042] As a preferred embodiment, three second semicircular bodies 22, located near the final stage of the stone, are staggered on the clamping surface of the first semicircular body 21. During the clamping process, the first semicircular bodies 21 and second semicircular bodies 22 of each clamping unit are staggered and compressed to share the clamping force, thereby improving the overall stability of the follow-up clamping unit in the clamping state.

[0043] As a preferred embodiment, the inner surface of the second semicircular body 22, which is closest to the stone, is provided with a flexible layer. The flexible layer structure fits snugly against the inner surface of the semicircle, preventing slippage and breakage between the rigid joints when the arc-shaped slide rail 213 and the arc-shaped slide groove 212 slide together, thus improving the stability of the device.

[0044] As a preferred embodiment, the outer surface of the second semicircular body 22, which is closest to the stone, is provided with a protruding buffer pad. This increases the friction between the outer surface of the second semicircular body 22 and the stone, thereby further enhancing the device's stable grip on the stone.

[0045] As a preferred method, the number of multi-stage follower clamping units is three, which is used for the loading and unloading process of garden landscape stones. Considering factors such as material cost, stone type, shape, and volume, the three-stage follower clamping unit is more suitable for this type of device.

[0046] As a preferred embodiment, both the first semicircular body 21 and the first semicircular body 21 are made of rigid material. Since garden landscape stones come in various types, rigid materials are suitable for the loading, unloading, and clamping of such stones due to their hardness, and the cost is reasonable and economical.

[0047] As a preferred embodiment, the outer arm of the gripping arm is provided with a pulley line track, and a pulley line is threaded through the pulley line track. One end of the pulley line is fixedly connected to a first semicircular body close to the stone. When clamping the stone, the force of lifting the stone can be converted into a clamping force close to the stone through the pulley line fixedly connected to the first semicircular body.

[0048] As a preferred embodiment, the sides of the first semicircular body 21 near the stone protrude beyond the sides of the first semicircular body 21 near the stone. This avoids the situation where, during clamping, one side of the semicircular body slides into the semicircular arc due to the force distribution on both sides, reducing the force-bearing area and lowering the force-bearing direction.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
