Description

Technical Field

[0001] The invention relates to the technical field of steel mesh transportation, in particular to a steel mesh grabbing device suitable for steel meshes of various specifications and sizes. Background Art

[0002] Steel mesh is a shaped steel product made of steel bars arranged with equal or unequal spacing in the horizontal and vertical directions, and tied and welded at the intersection of the horizontal and vertical steel bars to form a mesh. It is mainly used in the foundation slabs and wall panels of reinforced concrete structures. After the steel bars are produced, the stacked meshes are hoisted to the prefabricated component production line.

[0003] According to the patent application with publication number CN209226445U, the steel mesh grabbing, conveying and storage equipment integrates the functions of grabbing, conveying and storage, has diverse and comprehensive functions, works safely and reliably, has a high degree of intelligence, and greatly improves production efficiency;

[0004] Although the above device can grab and transport the steel mesh, in actual operation, especially when grabbing multi-layer stacked steel mesh, the above grabbing method is difficult to adaptively adjust the position of the grabbed steel mesh during operation, and the grabbing component and the steel mesh frame are easily misaligned, making it impossible to accurately grab the mesh and maintain a balanced state during lifting;

[0005] At the same time, in most cases, conventional mechanical grippers can only clamp a single set of steel mesh at a time, especially for larger steel meshes. It is difficult to grasp multi-layer meshes. Not only is it easy for the top single-layer or multi-layer meshes to affect the stability of the mesh stacking below the grasping layer, thereby affecting the continuous grasping effect, but the steel mesh frames on both sides are prone to uneven force due to the uneven bending defects of the steel mesh frames in some interlayers, causing the grasped steel mesh to fall off, thereby reducing the grasping efficiency of the steel mesh.

[0006] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

[0007] The purpose of the present invention is to achieve multi-directional limited grabbing of single-layer or multi-layer steel meshes on the basis of automatic straightening of steel meshes of different specifications, thereby ensuring that the stability of the steel mesh plate below the grabbing layer is not affected, avoiding the situation where the frame of the grabbed single-layer or multi-layer steel mesh falls off due to uneven force, and improving the grabbing efficiency of the steel mesh.

[0013] Furthermore, the two groups of push strips extend away from each other at one end to the outside of the material grabbing frame and are fixedly installed with a T-shaped support frame. A convex sliding shaft is fixedly installed at the bottom center of each group of push strips, and sliding grooves are provided at the bottom surface of the material grabbing frame and at the corresponding positions of the two groups of convex sliding shafts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention utilizes a pair of cylinders to push the material grabbing frames horizontally to the upper end of the steel mesh stacking group, and then utilizes a second cylinder to vertically sink the material grabbing frames, thereby forcing the material grabbing frames to be close to the steel mesh, and then utilizes a motor to drive the gear ring to rotate, thereby causing the fan-shaped gear disc and the swing bar to deflect, and the two groups of push bars to move to the outside of the material grabbing frames respectively, thereby the convex sliding shaft simultaneously slides along the inside of the slide groove and the inclined groove, forcing the front and rear two groups of slide plates and their bottom vertical rods to be close to the steel mesh respectively, and utilizing the vertical rods to straighten the steel mesh of the clamping layer and the mesh of the next layer of the clamping layer, which not only keeps the clamping parts aligned with the steel mesh, facilitating the subsequent grabbing part to quickly grab the mesh, but also ensures that the stability of the steel mesh stacked below the grabbing layer is not affected, thereby assisting in improving the grabbing efficiency of the steel mesh;

[0018] The present invention also drives the gear to rotate in the opposite direction through a motor, forcing the toothed disc and the swing bar to deflect in the opposite direction, and the two groups of push bars move toward the inside of the material grabbing frame, and respectively pull the corresponding T-shaped abutment frames closer to each other, and the left and right rows of concave vertical frames are respectively located at the side edges of the steel mesh of the clamping layer, and along with the two rows of concave vertical frames, the tip of the bevel guide block is first inserted into the gap between the two groups of steel meshes, and then the steel mesh of the top layer is lifted up and separated from the steel mesh plate of the lower layer, and at the same time, the steel mesh frame of the top layer continues to slide upward along the inclined surfaces of several groups of bevel guide blocks into the notch groove, and slide along the inclined surface of the clamping block, forcing the clamping block to sink into the inner cavity, and the spring damping shock absorber is compressed until the steel mesh stays between the inner wall at the top of the notch groove of the concave vertical frame and the clamping block, then the concave vertical frame can be stopped from moving, therefore, the upper and lower ends and sides of the steel mesh are pressed and clamped, and the structure can adaptively clamp and grab steel meshes of different specifications and different numbers of layers at the same time, thereby improving the grabbing efficiency of the steel mesh.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 - Figure 7As shown, a steel mesh grabbing device suitable for multiple specifications and sizes includes a movable long frame 1 and a material guide frame 2, the material guide frame 2 is arranged in an inclined structure, and the bottom inner wall of the material guide frame 2 is located at the higher end and is arranged in a mesh surface, the movable long frame 1 is fixedly installed at the top of the material guide frame 2 at the higher end through a connecting rod, a cylinder 3 is arranged at the center of the inner wall of one side of the movable long frame 1, and one end of the cylinder 3 is fixedly installed with an H-shaped frame 4 through a push rod 301, and the front and rear ends of the H-shaped frame 4 are respectively slidably connected to the inside of the transverse groove 101 opened on the front and rear inner walls of the movable long frame 1, a cylinder 2 5 is arranged at the center of the top of the H-shaped frame 4, and the bottom of the cylinder 2 5 extends to the bottom of the H-shaped frame 4 and is provided with a push rod 2 501, and a grabbing frame 6 is fixedly installed at the bottom of the push rod 2 501;

[0030] Slide frames 601 are provided at both ends of the bottom of the material grabbing frame 6, and slide plates 602 are movably connected at the front and rear ends between the two groups of slide frames 601. The ends of the two groups of slide plates 602 away from each other extend to the outside of the slide frames 601, and each group of slide plates 602 is provided with an inclined groove 603 inside. The front and rear groups of inclined grooves 603 are arranged diagonally, and the ends of the front and rear groups of slide plates 602 away from each other are located at the corners on both sides, and the opposite surfaces of the vertical poles 604 of the two adjacent groups are located at the bottom and are arranged in an inclined surface. A limiting mechanism 7 is arranged inside the material grabbing frame 6;

[0031] Multiple groups of steel mesh sheets are stacked at the bottom of the movable long frame 1 on one side of the material guide frame 2, and then the cylinder 1 3 is started, which uses the push rod 1 301 to push the H-shaped frame 4 and the material grabbing frame 6 to move in a straight line until the material grabbing frame 6 moves to the upper end of the steel mesh sheet, and then the cylinder 2 5 is started, which uses the push rod 2 501 to pull the material grabbing frame 6 to settle until the material grabbing frame 6 settles to the steel mesh sheet close to the top layer, and the four groups of vertical rods 604 settle with the material grabbing frame 6 and are located at the front and rear ends of the two groups of steel mesh sheets on the top layer. During the settlement process of the vertical rods 604, the frame of the steel mesh sheet protruding from the front and back is pressed and pushed, and then the limiting mechanism 7 is used to straighten and adaptively clamp the two sides of the steel mesh sheet;

[0032] After the steel mesh is grabbed, the cylinder 2 5 is driven again, and the push rod 2 501 is used to pull the grabbing frame 6 and the clamped mesh plate upward until the bottom of the steel mesh is in the same plane as the guide frame 2, and then the cylinder 1 3 is used to drive the H-shaped frame 4, the grabbing frame 6 and the clamped steel mesh to move to the guide frame 2. The steel mesh moves to the higher end of the frame opening of the guide frame 2. After the clamping of the limit mechanism 7 is released, the steel mesh falls into the guide frame 2. At the same time, the mesh contacts the inner wall of the guide frame 2 and collides slightly, thereby the filler blocked by the mesh of the inner wall is automatically ejected to keep the mesh of the steel mesh unobstructed. Subsequently, the mesh slides down the inclined guide frame 2 to the operating table for further processing, thereby completing the unloading of the steel mesh;

[0033] Example 2: Please refer to Figure 3 - Figure 5 As shown, a limiting mechanism 7 is arranged inside the material grabbing frame 6, and the limiting mechanism 7 includes a motor 701, which is arranged at the inner wall of the front end of the material grabbing frame 6 through a machine base, and the bottom output end of the motor 701 extends to the lower end of the machine base and is fixedly installed with a gear ring 702, and the rear end of the gear ring 702 is movably connected with a fan-shaped toothed disc 703, and the gear ring 702 is meshed with the opposite surface of the fan-shaped toothed disc 703, and a swing bar 704 is fixedly installed at one end of the fan-shaped toothed disc 703 away from the gear ring 702, and the bottom center of the swing bar 704 is hinged with the center of the bottom inner wall of the material grabbing frame 6, and a long groove 705 is arranged at the rear end of the swing bar 704;

[0034] Push bars 706 are provided near the front and rear ends at the center of the bottom surface of the swing bar 704, and the end of the push bar 706 connected to the swing bar 704 is arranged in a bent structure, and the two groups of push bars 706 are arranged in opposite structures, the top of the front push bar 706 is hinged with the swing bar 704, and the top end of the rear push bar 706 is provided with a round shaft 707, and the round shaft 707 is slidably connected inside the long groove 705, and the ends of the two groups of push bars 706 away from each other are extended to the outside of the material grabbing frame 6 and fixedly installed with a T-shaped abutment frame 708, and a convex sliding shaft 709 is fixedly installed at the center of the bottom of each group of push bars 706, and a sliding groove 710 is opened at the bottom surface of the material grabbing frame 6 corresponding to the two groups of convex sliding shafts 709, and the convex sliding shaft 709 passes through the corresponding sliding groove 710 and the inside of the inclined groove 603 in sequence;

[0035] After the upright pole 604 sinks with the material grabbing frame 6, the motor 701 is started, which first drives the gear ring 702 to rotate clockwise, and the fan-shaped gear disc 703 meshes with the gear ring 702 and rotates counterclockwise with the swing bar 704. The two ends of the swing bar 704 push the two groups of push bars 706 to move to the two sides of the material grabbing frame 6, and the two groups of T-shaped abutment frames 708 move away from each other, and the distance between the T-shaped abutment frames 708 and the side frames of the steel mesh plate increases, and the convex sliding shaft 709 moves linearly with the push bars 706, and slides along the slide groove 710 and the inside of the inclined groove 603 at the same time;

[0036] Therefore, the inside of the inclined groove 603 is pressed and forces the slide plate 602 to move into the slide frame 601, and the front and rear groups of slide plates 602 approach each other, and drive the corresponding vertical rods 604 to press against the front and rear end surfaces of the two groups of steel mesh panels on the top layer, forcing the two groups of steel mesh panels on the upper layer to be aligned in the center. At this time, the steel mesh panels on the top layer are aligned with reference to the steel mesh panels on the next layer, so as to prevent the steel mesh panels on the lower layer from deflecting and tipping over when the top steel mesh panels are subsequently grabbed, thereby improving the stability of the stacked steel mesh panels and the grabbing efficiency of the mesh panels to be clamped.

[0037] Example 3: Please refer to Figure 3 , Figure 6 - Figure 7As shown, a plurality of groups of concave vertical frames 8 of longitudinal structure are fixedly installed at equal distances at the bottom of the T-shaped abutment frame 708, and the notched grooves of the concave vertical frames 8 correspond to the left and right sides of the material grabbing frame 6. After the front and rear positions of the steel mesh of the grabbing layer are adjusted, the motor 701 is started again, and the driving gear ring 702 rotates counterclockwise, so that the fan-shaped gear disc 703 and the swing bar 704 deflect clockwise and respectively pull the two groups of push bars 706 to move inside the material grabbing frame 6. Therefore, the convex sliding shaft 709 slides in the opposite direction along the inside of the inclined groove 603. Similarly, due to the pressure on the inner wall of the inclined groove 603, the two groups of slide plates 602 are forced to move to the outside of the sliding frame 601 respectively, and the vertical rod 604 loses the pressure on the front and rear end frame edges of the steel mesh. At the same time, the two groups of push bars 706 pull the two groups of T-shaped abutment frames 708 closer to each other, and the concave vertical frame 8 moves toward the frame of the steel mesh, and the sharp corner at the lower end of the bevel guide block 801 is located at the gap between the two layers of steel mesh at the top.

[0038] An angled guide block 801 is provided on one side of the concave vertical frame 8 close to the material grabbing frame 6 and at the bottom end of the notch groove, and a roller 802 is embedded in the inclined surface of the angled guide block 801. An inner cavity 803 is provided on the inner wall at the bottom of the concave vertical frame 8. As the left and right rows of concave vertical frames 8 continue to approach the frames on both sides of the steel mesh, the tip of the angled guide block 801 is first inserted into the gap between the two groups of steel meshes, and then the top layer of steel mesh is lifted up and separated from the steel mesh plate of the lower layer. At the same time, the frame of the top layer of steel mesh continues to slide upward along the inclined surfaces of several groups of angled guide blocks 801, and the roller 802 assists in accelerating the sliding speed of the steel mesh until the concave vertical frame 8 moves to the notch groove;

[0039] The inner cavity 803 is provided with a block 804 running through it, the top of the block 804 extends to the inner wall at the top of the notch groove, and one side of the block 804 is located at the top and is arranged in an oblique section, and a spring damping shock absorber 805 is provided between the bottom end of the block 804 and the inner wall at the bottom of the inner cavity 803. Because the steel mesh is continuously compressed, it slides along the inclined surface of the block 804, forcing the block 804 to sink into the inner cavity 803, and the spring damping shock absorber 805 is compressed until the steel mesh stays between the inner wall at the top of the notch groove of the concave frame 8 and the block 804, and the concave frame 8 can be stopped from moving. Therefore, the upper and lower ends and side edges of the steel mesh are clamped, and this structure can not only press the frame frames on both sides of the steel mesh to further center and straighten it, but also facilitate the adaptive pressing and clamping according to the thickness and length of the steel mesh frame, so as to realize multi-directional locking of the mesh, so as to avoid the mesh from being grasped and falling off during the grasping process, and further improve the stability during the grasping process.

[0040] It is worth noting that, due to the various specifications of the steel mesh, the specific steel mesh length and frame thickness can be adjusted adaptively when grasping. The length of the steel mesh can be adjusted by adjusting the spacing between the left and right sets of T-shaped abutment frames 708, and the frame thickness of the steel mesh can be adjusted by adjusting the spacing between the clamping block 804 and the inner wall of the top of the notch groove of the concave vertical frame 8. The clamping block 804 can be lifted upward or compressed downward by itself, so that it can adapt to the multi-directional clamping of steel meshes of various specifications, forcing the steel mesh to be more stable when grasping;

[0041] It is also worth mentioning that the device can not only clamp a single group of meshes, but also be suitable for clamping multiple groups of meshes. During the clamping process, the cylinder 2 5 is first used to drive the grasping frame 6 to sink, forcing the bottom of the vertical rod 604 to sink to the lower layer of the mesh to be clamped. Similarly, with the steel mesh of the next layer of the clamping layer as a reference, it and the meshes stacked above are straightened forward and backward, and then the above steps are repeated to clamp the side frames of the multiple groups of steel meshes to the corresponding notches of the concave vertical frame 8, and press the block 804 to sink according to the thickness of the stacked steel meshes, and the frames of the multiple groups of steel meshes are adaptively clamped between the block 804 and the inner wall at the top of the notch. Therefore, the stacking and grabbing of multiple groups of meshes is realized, which is more practical.

[0042] The working process and principle of the present invention are as follows:

[0043] When the present invention is in use, multiple groups of steel mesh sheets are stacked at the bottom of the movable long frame 1 on one side of the material guide frame 2, and then the cylinder 1 3 is started, which uses the push rod 1 301 to push the H-shaped frame 4 and the material grabbing frame 6 to move linearly until the material grabbing frame 6 moves to the upper end of the steel mesh sheet, and then the cylinder 2 5 is started, which uses the push rod 2 501 to pull the material grabbing frame 6 to settle, until the material grabbing frame 6 settles to the steel mesh sheet close to the top layer;

[0044] The four groups of vertical rods 604 sink with the material grabbing frame 6 and are located at the front and rear ends of the two groups of steel mesh plates on the top layer. Then the motor 701 is started, which first drives the gear ring 702 to rotate clockwise, and the fan-shaped gear plate 703 and the swing bar 704 to rotate counterclockwise. The swing bar 704 pushes the two groups of push bars 706 to move to the two sides of the material grabbing frame 6, and the convex sliding shaft 709 slides along the slide groove 710 and the inside of the inclined groove 603 at the same time. The front and rear groups of slide plates 602 approach each other and drive the corresponding vertical rods 604 to press against the front and rear ends of the two groups of steel mesh plates on the top layer, forcing the steel mesh on the top layer to be aligned with the steel mesh on the next layer.

[0045] After the front and rear positions of the steel mesh of the grabbing layer are adjusted, the motor 701 is started again, and the driving gear ring 702 rotates counterclockwise, so that the fan-shaped gear plate 703 and the swing bar 704 deflect clockwise, and the convex sliding shaft 709 slides in the opposite direction along the inside of the inclined groove 603, forcing the two groups of slide plates 602 to move to the outside of the sliding frame 601 respectively, and the vertical rod 604 loses the pressure on the front and rear end frames of the steel mesh. At the same time, the two groups of push bars 706 pull the two groups of T-shaped frames 708 closer to each other, and the concave vertical frame 8 moves toward the frame of the steel mesh, and the tip of the bevel guide block 801 is first inserted into the gap between the two groups of steel mesh;

[0046] Then, the top layer of steel mesh is lifted up and separated from the steel mesh plate of the lower layer. At the same time, the frame of the top layer of steel mesh continues to slide upward along the inclined surfaces of the plurality of groups of bevel guide blocks 801 until the concave vertical frame 8 moves to the notch groove. Then, due to the continuous pressure on the steel mesh, it slides along the inclined surface of the clamping block 804, forcing the clamping block 804 to sink into the inner cavity 803. The spring damping shock absorber 805 is compressed until the steel mesh stays between the inner wall at the top of the notch groove of the concave vertical frame 8 and the clamping block 804. Then, the concave vertical frame 8 can be stopped from moving. Both sides and the upper and lower frames of the steel mesh are pressed and clamped.

[0047] After the mesh is grabbed, the cylinder 2 5 is driven again, which uses the push rod 2 501 to pull the grab frame 6 and the clamped mesh plate upward until the bottom of the steel mesh is in the same plane as the guide frame 2, and then uses the cylinder 1 3 to drive the H-frame 4, the grab frame 6 and the clamped steel mesh to move to the guide frame 2. The steel mesh moves to the higher end of the frame opening of the guide frame 2, and the motor 701 drives the two sets of T-shaped abutment frames 708 to gradually move away, and the bottom frame of the steel mesh slowly slides downward along the inclined surfaces of the clamping block 804 and the bevel guide block 801 respectively, and the steel mesh falls into the guide frame 2, and the mesh slides down along the inclination of the guide frame 2 to the operating table for further processing, thereby completing the unloading of the steel mesh.
