Description

Technical Field

[0001] The present invention relates to the technical field of hoisting and clamping, and specifically relates to a clamping device for lifting and transporting building blocks. Background Technique

[0002] Building blocks are building materials used for building structures such as walls. They are usually made of materials such as concrete, cement, sand and gravel, and fly ash. They have various types and characteristics and are widely used in construction projects. The clamping device for lifting and transporting is a tool used to clamp, fix and transport objects such as building blocks through hoisting equipment in fields such as construction or logistics. It can provide reliable clamping force to ensure the stability and safety of objects during hoisting and transportation, and prevent objects from falling and causing personal injuries or property losses; During the working process of the existing clamping equipment, only through the clamping components on both sides, the top building blocks are less restricted during the hoisting and transportation of the building block stack, resulting in the top building blocks falling during transportation. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: A clamping device for lifting and transporting building blocks, comprising: A support beam, on both sides of which cylinders are fixedly installed, and side shafts are fixedly installed at both ends of the support beam; A clamping mechanism, which is installed at both ends of the support beam, and the clamping mechanism is rotatably connected to the support beam through the side shafts; A connection mechanism, which is used to connect with the hoisting equipment and buffer during hoisting, and the connection mechanism is installed on the top of the support beam; On both sides of the bottom of the support beam, connecting beams are fixedly installed. Fixed columns are fixedly installed at the bottoms of the connecting beams. The bottom ends of the fixed columns are fixedly installed with top plates. At both ends of the bottom of the top plate, inner inclined plates are fixedly installed. The opposite surfaces between the inner inclined plates are inclined surfaces that slope outward from top to bottom. And an axial groove is provided at the bottom end of the inner inclined plate. Rotating columns are rotatably installed at the axial grooves of the inner inclined plates. Through the cooperation of the rotating columns and the inner inclined plates, during the process of the clamping mechanism clamping the block stack, the rotating columns are used to contact the top of the block stack. During the offset process, the rotation of the rotating columns reduces the frictional resistance, so that during the position adjustment process, it is avoided that the resistance is too large, driving the top block stack and causing the top blocks to fall, affecting the clamping and transportation of the blocks. A pressing plate is installed at the bottom of the top plate. Through the cooperation of the pressing plate and the inner inclined plates, during the process of clamping the block stack, it cooperates with the clamping mechanism to increase the contact pressure between the pressing plate and the top of the block stack, causing the elastic cushion ring to deform. The inclined surfaces of the inner inclined plates are in contact with both sides of the top of the block stack. While the pressing plate restricts the top of the block stack, the inner inclined plates cooperate with the clamping mechanism to restrict the four sides of the top of the block stack, so that during the hoisting and transportation process of the block stack, it is avoided that the blocks at the top of the block stack fall during the transportation bumps, resulting in danger during hoisting and transportation. The two sides of the top of the pressing plate are slidably adapted to the outer side of the top plate through fasteners. And an elastic cushion ring is fixedly installed between the pressing plate and the top plate. The elastic cushion ring is made of elastic metal material. The pressing plate is located at the central position between the inner inclined plates.

[0004] Preferably, the connecting mechanism includes a fixed frame. The fixed frame is fixedly installed on the top of the support beam. A rectangular groove is provided at the central position of the top of the fixed frame. And an inner sliding plate is slidably installed inside the fixed frame. The inner sliding plate is in close fit with the fixed frame. A limiting column is fixedly installed at the top of the inner wall of the fixed frame. The bottom end of the limiting column penetrates through the inner sliding plate and extends to the top of the support beam. And the bottom end of the limiting column is fixedly connected to the top of the support beam. The limiting columns are symmetrically installed along the central axis of the fixed frame. A spring is fixedly installed between the top of the inner sliding plate and the inner wall of the fixed frame. Through the cooperation of the spring and the inner sliding plate, during the hoisting process, by pulling the inner sliding plate upward and compressing the spring to deform, during the elastic deformation of the spring, the hoisting tension is buffered, reducing the tension on the block stack at the moment of hoisting, avoiding the direct transmission of the tension to the block stack without buffering, resulting in large bumps of the block stack at the moment of hoisting and causing the block stack to become loose, affecting the safety of transportation. The spring is located outside the limiting column. A connecting block is fixedly installed at the central position of the top of the inner sliding plate. The outer side of the connecting block is slidably adapted to the rectangular groove of the fixed frame. And a connecting plate is fixedly installed at the top end of the connecting block.

[0005] Preferably, the clamping mechanism includes a clamping frame. Sleeve shaft plates are symmetrically installed at the top of the clamping frame. Shaft holes are provided on the outer sides of the sleeve shaft plates, and the shaft holes of the sleeve shaft plates are rotationally adapted to both ends of the outer side of the side shaft. Fixing plates are fixedly installed at both ends of the outer side of the clamping frame. One end of the fixing plate away from the clamping frame is inclined upward and is provided with a rotating groove. A clamping shaft block is rotatably installed at the rotating groove of the fixing plate. One end of the clamping shaft block away from the fixing plate is rotationally adapted to the output end of the air cylinder. Card slot plates are fixedly installed at the bottoms of the opposite surfaces of the clamping frame. Card slots are provided on the opposite surfaces of the card slot plates, and bottom cushion plates are clamped at the card slots of the card slot plates. By cooperating with the bottom clamping claws, during the clamping process, in line with the characteristic that the end of the bottom clamping claw away from the clamping frame is inclined downward, while clamping, the block stack is driven to move upward. Cooperating with the pressing plate and the inner inclined plate, the restriction on the stacked block stack is increased. At the same time, the bottom cushion plate contacts the bottom layer of the block stack after clamping, increasing the friction force to prevent the blocks from sliding relative to the clamping device during transportation. The bottom cushion plate is made of rubber material.

[0006] Preferably, a bottom clamping claw is fixedly installed at the bottom end of the clamping frame. The bottom clamping claws are uniformly installed along the axis, and the end of the bottom clamping claw away from the clamping frame is inclined downward. Folding plates are fixedly installed on the opposite surfaces of the clamping frame. The bottom end of the folding plate has a horizontal plate that folds inward, and the opposite surfaces of the folding plate are inclined surfaces that incline inward from top to bottom. Sliding grooves are uniformly provided on the inclined surfaces of the folding plate. Oblique sliding plates are slidably installed at the sliding grooves of the folding plate. By cooperating the oblique sliding plates with the sliding grooves on the inclined surfaces of the folding plate, during the clamping process, the rubber cushion strips are used to contact the side of the cut block stack. When the block stack has a tendency to slide downward during movement, through the friction between the rubber cushion strips and the cut blocks, the tendency is transmitted to the oblique sliding plates, causing them to have a tendency to move downward and compress the elastic cushion strips. Through the inclined surfaces of the oblique sliding plates and the folding plates, the oblique sliding plates have a tendency to move inward to restrict the falling of the block stack. Rubber cushion strips are fixedly installed on the opposite surfaces of the oblique sliding plates. An elastic cushion strip is fixedly installed at the top of the horizontal plate of the folding plate, and the top of the elastic cushion strip is in close contact with the bottom of the oblique sliding plate.

[0007] The present invention provides a clamping device for lifting and transporting blocks. It has the following beneficial effects: First, in this clamping device for lifting and transporting blocks, through the cooperation of the rotating column and the inner inclined plate, during the process of the clamping mechanism clamping the block stack, the rotating column is used to contact the top of the block stack. During the offset process, the rotational movement of the rotating column reduces the frictional resistance, so that during the position adjustment process, it is avoided that the resistance is too large, driving the top layer of the block stack and causing the top layer of blocks to fall, affecting the clamping and transportation of the blocks.

[0008] Second, the clamping device for lifting and transporting the building blocks, through the cooperation of the pressure plate and the inner inclined plate, during the process of clamping the building block stack, in cooperation with the clamping mechanism, increases the contact pressure between the pressure plate and the top of the building block stack, causing the elastic pad to deform annularly, making the inclined surface of the inner inclined plate contact the two sides of the top of the building block stack. While restricting the top of the building block stack with the pressure plate, the inner inclined plate cooperates with the clamping mechanism to restrict the four sides of the top of the building block stack, so that during the hoisting and transportation process of the building block stack, it can be avoided that the building blocks at the top of the building block stack fall during the transportation bumps, resulting in danger during hoisting and transportation.

[0009] Third, the clamping device for lifting and transporting the building blocks, through the cooperation of the spring and the inner sliding plate, during the lifting process, by pulling the inner sliding plate upward, compressing the spring to deform, during the elastic deformation of the spring, it buffers the lifting force, reduces the pulling force on the building block stack at the moment of lifting, and avoids the direct transmission of the pulling force to the building block stack without buffering, resulting in a large bump of the building block stack at the moment of lifting, causing the building block stack to become loose and affecting the transportation safety.

[0010] Fourth, the clamping device for lifting and transporting the building blocks, through the cooperation of the bottom cushion plate and the bottom clamping claws, during the clamping process, with the characteristic that one end of the bottom clamping claws away from the clamping frame inclines downward, while clamping, it drives the building block stack to move upward, in cooperation with the pressure plate and the inner inclined plate, increasing the restriction on the stacked building blocks. At the same time, the bottom cushion plate contacts the bottom building block stack after clamping, increasing the friction force to avoid relative sliding between the building blocks and the clamping device during transportation.

[0011] Fifth, the clamping device for lifting and transporting the building blocks, through the cooperation of the inclined sliding plate and the chute on the inclined surface of the zigzag plate, during the clamping process, uses the rubber cushion strip to contact the side of the building block stack. When the building block stack has a tendency to slide downward during the movement process, through the friction between the rubber cushion strip and the building block, the tendency is transmitted to the inclined sliding plate, causing it to have a tendency to move downward, compressing the elastic cushion strip. Through the inclined surface of the inclined sliding plate and the zigzag plate, the inclined sliding plate has a tendency to move inward, restricting the falling of the building block stack.

Specific embodiments

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] The first embodiment is as Figures 1 to 5 shown, and the present invention provides a technical solution: A clamping device for lifting and transporting building blocks, comprising: A support beam 1, on both sides of which cylinders 4 are fixedly installed, and side shafts 5 are fixedly installed at both ends of the support beam 1; A clamping mechanism 2, which is installed at both ends of the support beam 1, and the clamping mechanism 2 is rotatably connected to the support beam 1 through the side shaft 5; A connection mechanism 3, which is used to connect with the lifting equipment and buffer during the lifting process, and the connection mechanism 3 is installed on the top of the support beam 1; On both sides of the bottom of the support beam 1, connecting beams 9 are fixedly installed. On the bottom of each connecting beam 9, a fixed column 10 is fixedly installed. At the bottom end of the fixed column 10, a top plate 12 is fixedly installed. At both ends of the bottom of the top plate 12, inner inclined plates 6 are fixedly installed. During the process of wrapping the block stack from top to bottom, the clamping device driven by the lifting device moves downward from the top of the block stack. Through the inner inclined plate 6 and the pressing plate 7, the top and side of the block stack are released. Through the cooperation of the inclined surface of the inner inclined plate 6 and the rotating column 8, during the downward movement, the rotating column 8 first contacts the block. When the position of the block is offset from the position of the clamping device, the position of the clamping device can be adjusted by the lifting device. The opposite surfaces of the inner inclined plates 6 are inclined surfaces that slope outward from top to bottom. And at the bottom end of the inner inclined plate 6, a shaft groove is provided. Rotating columns 8 are rotatably installed at the shaft grooves of the inner inclined plates 6. A pressing plate 7 is installed at the bottom of the top plate 12. The two sides of the top of the pressing plate 7 are slidably adapted to the outside of the top plate 12 through fasteners. During the adjustment process, the rotation of the rotating column 8 is used to reduce the friction with the block and adjust the object position. When the position is determined, the clamping mechanisms 2 on both sides are driven to rotate by the cylinder 4 to clamp the block stack. During the clamping process, through the cooperation of the clamping mechanism 2 and the pressing plate 7, during the clamping process, the contact pressure between the pressing plate 7 and the top of the block stack is increased, so that the elastic cushion ring 11 deforms under the contact pressure, and the inner inclined plates 6 contact both sides of the top of the block stack, cooperating with the clamping mechanism 2 to restrict the four sides of the block stack. And an elastic cushion ring 11 is fixedly installed between the pressing plate 7 and the top plate 12. The elastic cushion ring 11 is made of elastic metal material. The pressing plate 7 is located at the central position between the inner inclined plates 6.

[0016] Second Embodiment. On the basis of the first embodiment, please refer to Figure 6 As shown, the connecting mechanism 3 includes a fixed frame 31. The fixed frame 31 is fixedly installed on the top of the support beam 1. A rectangular groove is provided at the central position of the top of the fixed frame 31. And an inner sliding plate 34 is slidably installed inside the fixed frame 31. The inner sliding plate 34 is in close fit with the fixed frame 31. It is connected to the lifting device through a connecting plate 36, so that the lifting device drives the clamping device through the connecting mechanism 3. At the same time, after clamping the block stack, the lifting device first transmits the traction force to the connecting mechanism 3. At the top of the inner wall of the fixed frame 31, a limiting column 33 is fixedly installed. The bottom end of the limiting column 33 penetrates through the inner sliding plate 34 and extends to the top of the support beam 1. And the bottom end of the limiting column 33 is fixedly connected to the top of the support beam 1. The limiting columns 33 are symmetrically installed along the central axis of the fixed frame 31.

[0017] A spring 32 is fixedly installed between the top of the inner sliding plate 34 and the inner wall of the fixed frame 31. The spring 32 is located outside the limit post 33. By driving the connecting block 35 and the inner sliding plate 34 through the connecting plate 36, the inner sliding plate 34 is compressed against the spring 32 under the restriction of the fixed frame 31 and the limit post 33. The elastic deformation of the spring 32 during compression elastically buffers the traction lifting force and reduces the vibration during lifting. A connecting block 35 is fixedly installed at the central position of the top of the inner sliding plate 34. The outer side of the connecting block 35 is slidably adapted to the rectangular groove of the fixed frame 31, and a connecting plate 36 is fixedly installed at the top end of the connecting block 35.

[0018] The third embodiment is based on the first and second embodiments. Please refer to Figures 7 to 9 As shown, the clamping mechanism 2 includes a clamping frame 201. Sleeve shaft plates 204 are symmetrically installed at the top of the clamping frame 201. Shaft holes are formed on the outer sides of the sleeve shaft plates 204, and the shaft holes of the sleeve shaft plates 204 are rotationally adapted to both ends of the outer side of the side shaft 5. Fixing plates 202 are fixedly installed at both ends of the outer side of the clamping frame 201. One end of the fixing plate 202 away from the clamping frame 201 is inclined upward and is provided with a rotating groove. A clamping shaft block 203 is rotatably installed at the rotating groove of the fixing plate 202. One end of the clamping shaft block 203 away from the fixing plate 202 is rotationally adapted to the output end of the cylinder 4. By connecting the fixing plate 202 to the output end of the cylinder 4, the clamping frame 201 is rotated by driving the fixing plate 202 through the output end of the cylinder 4 to open and close. During the process of the clamping frames 201 rotating towards each other, contact is made with the side of the block stack through the rubber gasket strip 205 located above. Bottom clamping plates 206 are fixedly installed at the bottoms of the opposite surfaces of the clamping frame 201. Clamping grooves are formed on the opposite surfaces of the bottom clamping plates 206, and bottom cushion plates 206 are clamped at the clamping grooves of the bottom clamping plates 206. The bottom cushion plates 206 are made of rubber material.

[0019] The bottom end of the clamping frame 201 is fixedly installed with bottom clamping claws 207. The bottom clamping claws 207 are evenly installed along the axial direction, and the end of the bottom clamping claw 207 away from the clamping frame 201 is inclined downward. Opposite surfaces of the clamping frame 201 are fixedly installed with zigzag plates 210. The bottom end of the zigzag plate 210 has a horizontal plate that zigzags inward, and the opposite surfaces of the zigzag plate 210 are inclined surfaces that slope inward from top to bottom. During the contact process, the rubber cushion strips 205 from top to bottom in position sequentially contact the block stack. Finally, the bottom clamping claws 207 at the bottom end of the clamping frame 201 contact the bottom edge position of the block stack. At the same time, during the clamping process, by using the end of the bottom clamping claw 207 away from the clamping frame 201 to be inclined downward, when the bottom clamping claw 207 clamps, the contact pressure with the pressure plate 7 increases during the process of driving the block stack to move upward. At the same time, the bottom clamping claw 207 cooperates with the bottom backing plate 206. During the process of the bottom clamping claw 207 clamping, the bottom of the outside of the block stack contacts the bottom backing plate 206 to clamp the bottom of the block stack. The inclined surfaces of the zigzag plate 210 are evenly provided with sliding grooves. Slant sliding plates 209 are slidably installed at the sliding groove positions of the zigzag plate 210. Rubber cushion strips 205 are fixedly installed on the opposite surfaces of the slant sliding plates 209. An elastic cushion strip 211 is fixedly installed at the top of the horizontal plate of the zigzag plate 210, and the top of the elastic cushion strip 211 is in close contact with the bottom of the slant sliding plate 209.

[0020] During use, connect the clamping device to the lifting equipment, fixedly connect the lifting equipment to the connecting mechanism 3, and connect the pneumatic control pipeline of the air cylinder 4 to the lifting equipment. Control the operation of the air cylinder 4 through the lifting equipment. During the working process, control the air cylinder 4 to extend through the lifting equipment, so that the clamping mechanisms 2 on both sides open, and wrap the stacked block stack from top to bottom. After the wrapping is completed, contract the output end of the air cylinder 4 to make the clamping mechanisms 2 on both sides clamp inward to clamp and fix the block stack. Subsequently, drive the connecting mechanism 3 through the lifting equipment to lift and transport the clamping device and the block stack simultaneously.

[0021] During the process of wrapping the block stack from top to bottom, the clamping device driven by the lifting equipment moves downward from the top of the block stack. The inner inclined plate 6 contacts the top and side of the block stack through the pressure plate 7. Through the cooperation of the inclined surface of the inner inclined plate 6 and the rotating column 8, during the downward movement, the rotating column 8 first contacts the block. When the position of the block is offset from the position of the clamping device, the position of the clamping device can be adjusted through the lifting equipment. During the adjustment process, utilize the rotation of the rotating column 8 to reduce the friction with the block and facilitate the position adjustment. When the position is determined, drive the clamping mechanisms 2 on both sides to rotate through the air cylinder 4 to clamp the block stack. During the clamping process, through the cooperation of the clamping mechanism 2 and the pressure plate 7, during the clamping process, the contact pressure between the pressure plate 7 and the top of the block stack increases, causing the elastic cushion ring 11 to deform under the contact pressure, and making the inner inclined plate 6 contact both sides of the top of the block stack to cooperate with the clamping mechanism 2 to restrict the periphery of the block stack.

[0022] In the clamping mechanism 2, the fixed plate 202 is connected to the output end of the air cylinder 4. The output end of the air cylinder 4 drives the fixed plate 202, causing the clamping frame 201 to rotate for opening and closing. During the process of the clamping frames 201 rotating towards each other, the rubber gasket strip 205 located above contacts the side of the block stack. Meanwhile, during the contact process, the rubber gasket strips 205 from top to bottom sequentially contact the block stack. Finally, the bottom clamping claws 207 at the bottom end of the clamping frame 201 contact the bottom edge position of the block stack. Also, during the clamping process, the end of the bottom clamping claw 207 away from the clamping frame 201 is inclined downward. When the bottom clamping claw 207 clamps, the contact pressure between the block stack and the pressing plate 7 increases during the upward movement of the block stack driven by the bottom clamping claw 207. At the same time, the bottom clamping claw 207 cooperates with the bottom backing plate 206. When the bottom clamping claw 207 clamps, the bottom outside of the block stack contacts the bottom backing plate 206, clamping the bottom of the block stack.

[0023] In the connecting mechanism 3, the connecting plate 36 is connected to the lifting device, enabling the lifting device to drive the clamping device through the connecting mechanism 3. Also, after clamping the block stack, the lifting device first transmits the traction force to the connecting mechanism 3. The connecting plate 36 drives the connecting block 35 and the inner sliding plate 34. Under the restriction of the fixed frame 31 and the limiting column 33, the inner sliding plate 34 compresses the spring 32. The elastic deformation of the spring 32 during compression elastically buffers the traction and lifting force, reducing the vibration during lifting.
