Description

Technical Field

[0001] This application relates to the field of civil engineering technology, and in particular to a clamping and handling device. Background Technology

[0002] In the construction industry, precast concrete slabs, aerated concrete blocks, and decorative stone are essential building materials. These materials are generally characterized by their large weight, sharp edges, rough surfaces, and diverse sizes. During construction, these materials require frequent transfer operations, including horizontal transport from storage areas to construction sites, vertical transport between floors, precise positioning in confined spaces, and repeated short-distance movements.

[0003] Currently, the transfer of building materials mainly relies on manual handling. However, due to the sharp edges and rough surfaces of the materials, workers are prone to skin abrasions when they come into direct contact with them. Furthermore, the concentrated local pressure from the sharp edges of the materials on the palms during handling can easily lead to unstable grip and the risk of the materials slipping. Therefore, the method of handling materials by manual contact is not very convenient and has obvious shortcomings. Utility Model Content

[0004] To improve the convenience for workers when handling materials, this application provides a clamping handling device.

[0005] The clamping and conveying device provided in this application adopts the following technical solution:

[0006] A clamping and conveying device includes a housing with a handle and a clamping assembly inside the housing. The clamping assembly includes a connecting block on the top of the housing, with a first gripper and a second gripper hinged to both sides of the connecting block. The first gripper and the second gripper are respectively located at opposite ends of the housing. Both the first gripper and the second gripper are provided with clamping plates for clamping materials. The housing is provided with a driving assembly for driving the clamping assembly to clamp or release materials.

[0007] By adopting the above technical solution, when handling materials, the worker drives the first and second grippers to approach each other and clamp the materials through the drive component. After the materials are clamped inside the shell, the worker holds the handle and lifts the shell to transfer the materials. After reaching the designated location, the worker drives the first and second grippers to move away from each other through the drive component, and the materials are released from the shell, thus ending the material transfer.

[0008] This design allows operators to complete material transfer operations without direct contact with the materials, avoiding direct pressure on the hands from the sharp edges of the materials, significantly reducing the risk of hand abrasions and fatigue, and thus improving the convenience for workers when handling materials.

[0009] Optionally, the drive assembly includes a drive rod rotatably disposed within the housing. One end of the drive rod is disposed on the handle, and the other end passes through the connecting block and extends into the housing. The drive rod is provided with a first threaded section, and a slider is threadedly connected to the first threaded section. The slider is slidably disposed within the housing. A first connecting rod and a second connecting rod are respectively hinged to both sides of the slider. The end of the first connecting rod away from the slider is hinged to the first gripper, and the end of the second connecting rod away from the slider is hinged to the second gripper.

[0010] By adopting the above technical solution, when clamping materials, the worker holds the shell with one hand to restrict the rotation of the shell, and rotates the drive rod in the forward direction with the other hand. The rotation of the drive rod drives the first threaded section to rotate. Since the rotation of the shell is restricted, the rotation of the first threaded section drives the slider to move upward along the axis of the drive rod. At this time, the angle between the first connecting rod and the second connecting rod and the axis of the drive rod becomes smaller. The first connecting rod and the second connecting rod pull the first gripper and the second gripper to rotate in a direction that brings them closer to each other, thereby achieving clamping.

[0011] When releasing the material, the worker rotates the drive rod in the opposite direction. At this time, the first threaded section rotates in the opposite direction, the slider moves downward along the axis of the drive rod, the angle between the first and second connecting rods and the axis of the drive rod increases, and the first and second grippers rotate in a direction away from each other, thereby releasing the material.

[0012] The drive assembly allows users to grip and release materials with simple rotational movements, further improving the convenience of material handling for workers.

[0013] Optionally, an auxiliary plate is provided on the bottom surface of the housing. The auxiliary plate is positioned above the two clamping plates and encloses the two clamping plates to form a clamping space.

[0014] By adopting the above technical solution, the first and second grippers limit the material on the left and right sides, and the auxiliary plate limits the material in the horizontal direction. This ensures that the material is not only subjected to the force of the grippers on both sides during the clamping process, but also to the support force of the top auxiliary plate. This prevents the material from shaking or slipping due to the shift of the center of gravity or external vibration during the handling process, and improves the stability after clamping.

[0015] Optionally, the drive rod is provided with a second threaded section, and the auxiliary plate is threadedly connected to the second threaded section, wherein the first threaded section and the second threaded section have opposite thread directions.

[0016] By adopting the above technical solution, when clamping materials, the drive rod drives the second threaded section to rotate in the forward direction. Since the first threaded section and the second threaded section have opposite thread directions, the auxiliary plate descends along the axis of the drive rod, gradually approaches the material and abuts against the material surface, improving the clamping effect of the clamping assembly on the material. When releasing materials, the drive rod drives the second screw to rotate in the reverse direction, and the auxiliary plate rises along the axis of the drive rod. The rise of the auxiliary plate increases the clamping space and prevents the auxiliary plate from affecting the normal placement of the material.

[0017] Optionally, the end of the drive rod away from the second threaded segment is rotatably connected to the connecting block via a bearing.

[0018] By adopting the above technical solution, the bearing configuration can reduce the friction between the drive rod and the connecting block when the drive rod rotates, making the drive rod rotate more smoothly, reducing the force required for the operator to turn the handle, improving the convenience of operation, and also reducing the wear between the drive rod and the housing, extending the service life of the device.

[0019] Optionally, the handle is provided with a grip portion, which is cylindrical.

[0020] By adopting the above technical solution, the cylindrical grip increases the contact area between the handle and the human hand, making it easier for workers to grip the handle. The cylindrical grip is more ergonomic, making it easier for operators to grasp, making their hands more comfortable and reducing hand fatigue during handling.

[0021] Optionally, rubber pads are provided on the opposite end faces of the clamping plates.

[0022] By adopting the above technical solution, the rubber pad has elasticity and friction. The elasticity allows the rubber pad to better fit the material surface when clamping the material, avoiding damage to the material due to excessive clamping force and playing a role in protecting the material. The friction makes the grip between the clamping plate and the material more secure, preventing the material from slipping during transportation and improving the reliability of clamping.

[0023] Optionally, the housing is provided with relief grooves that correspond one-to-one with the first gripper and the second gripper, and the first gripper and the second gripper are slidably disposed in the corresponding relief grooves.

[0024] By adopting the above technical solution, the clearance groove provides space for the opening and closing movements of the first and second grippers, ensuring that the grippers can open and close smoothly. At the same time, it guides the movement of the first and second grippers, avoiding uneven clamping force or material slippage caused by skew, and improving the reliability of clamping.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] This application, by setting up a clamping component and a driving component, allows the worker to drive the clamping component to clamp the material during material handling. After the material is clamped inside the housing, the worker holds the handle and lifts the housing to transfer the material. Once the material reaches the designated location, the worker drives the clamping component to release the material, thus ending the material transfer. This setup allows the operator to complete the material transfer operation without directly contacting the material, avoiding direct pressure from the sharp edges of the material on the hand, significantly reducing the risk of hand abrasions and fatigue, and thus improving the convenience for workers when handling materials.

[0027] 1. By setting a second threaded section and an auxiliary plate, the first and second grippers limit the material on the left and right sides during clamping, and the auxiliary plate limits the material in the horizontal direction, thus preventing the material from shaking or slipping due to the shift of the center of gravity or external vibration during handling, and improving the stability after clamping.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses a clamping and handling device.

[0034] Reference Figure 1 A clamping and conveying device includes a housing 1, which is square in shape. A handle 2 is provided on the top surface of the housing 1. A gripping part 21 is fixedly connected to the handle 2. The gripping part 21 is cylindrical so that it is easy for a person to hold. A clamping component 3 and a driving component 4 are provided inside the housing 1. The driving component 4 drives the clamping component 3 to clamp or release the material.

[0035] Reference Figure 1 and Figure 2The clamping assembly 3 includes a connecting block 31 fixedly installed on the top of the housing 1. The central axis of the connecting block 31 is on the same straight line as the central axis of the housing 1. A first clamping claw 32 and a second clamping claw 33 are respectively hinged to both sides of the connecting block 31. The housing 1 is provided with relief grooves 5 corresponding to the first clamping claw 32 and the second clamping claw 33. The two relief grooves 5 are respectively set at opposite ends of the housing 1 and are vertically arranged. The first clamping claw 32 and the second clamping claw 33 are slidably arranged in the corresponding relief grooves 5. The ends of the first clamping claw 32 and the second clamping claw 33 away from the connecting block 31 are integrally formed with clamping plates 34. The opposing surfaces of the two clamping plates 34 are detachably connected with rubber pads 341 by Velcro. The rubber pads 341 increase the friction between the first clamping plates 34 and the second clamping plates 34 and the material, thereby improving the clamping stability.

[0036] Reference Figure 1 and Figure 2 The drive assembly 4 includes a drive rod 41 rotatably disposed inside the housing 1. The axis of the drive rod 41 is in the same straight line as the axis of the housing 1. One end of the drive rod 41 is fixedly connected to the handle 2, and the other end passes through the connecting block 31 and extends into the housing 1. The drive rod 41 is rotatably engaged with the connecting block 31 through a bearing. The bearing reduces the friction between the drive rod 41 and the housing 1, making the drive rod 41 rotate more smoothly.

[0037] Reference Figure 1 and Figure 2 A first threaded section 42 is coaxially provided on the drive rod 41, and a slider 43 is threadedly connected to the first threaded section 42. The slider 43 is slidably disposed inside the housing 1 along the axis of the drive rod 41. A first connecting rod 44 and a second connecting rod 45 are respectively hinged to both sides of the slider 43. The end of the first connecting rod 44 away from the slider 43 is hinged to the first gripper 32, and the end of the second connecting rod 45 away from the slider 43 is hinged to the second gripper 33.

[0038] When handling materials, the worker holds the housing 1 with one hand to restrict its rotation, and rotates the handle 2 in the forward direction with the other hand. The handle 2 drives the first threaded section 42 to rotate in the forward direction through the drive rod 41. Since the rotation of the housing 1 is restricted, the rotation of the first threaded section 42 drives the slider 43 to move upward along the axis of the drive rod 41. At this time, the angle between the first connecting rod 44 and the second connecting rod 45 and the axis of the drive rod 41 becomes smaller. The first connecting rod 44 and the second connecting rod 45 pull the first gripper 32 and the second gripper 33 to rotate in a direction that approaches each other. The two clamping plates 34 continuously approach each other and finally abut against the outer surface of the material to achieve clamping of the material.

[0039] After clamping, the worker holds handle 2 to lift housing 1 and transfer the material. Once the material reaches the designated location, the worker reverses the drive rod 41, causing the first threaded section 42 to rotate in the opposite direction. The slider 43 moves downward along the axis of drive rod 41, increasing the angle between the first connecting rod 44 and the second connecting rod 45 and the axis of drive rod 41. The first gripper 32 and the second gripper 33 drive the two clamping plates 34 to move away from each other. The two clamping plates 34 eventually detach from the material, and the material falls to the designated location. This design allows the operator to complete the material transfer operation without direct contact with the material, avoiding direct pressure on the hands from the sharp edges of the material, significantly reducing the risk of hand abrasions and fatigue, and thus improving the convenience for workers when handling materials.

[0040] Reference Figure 2 and Figure 3 To further improve the stability of the clamping assembly, an auxiliary plate 6 is integrally formed on the bottom of the housing 1. The length direction of the auxiliary plate 6 is perpendicular to the length direction of the clamping plate 34. The auxiliary plate 6 is set above the two clamping plates 34 and forms a clamping space (not shown in the figure) between the two clamping plates 34. A second threaded section is coaxially provided on the shaft of the drive rod 41. The auxiliary plate is threadedly connected to the second threaded section. The first threaded section 42 and the second threaded section have opposite thread directions.

[0041] When clamping the material, the drive rod 41 drives the second threaded section to rotate in the forward direction. Since the first threaded section 42 and the second threaded section have opposite thread directions, the auxiliary plate 6 descends along the axis of the drive rod 41. The auxiliary plate 6 gradually approaches the material and abuts against the surface of the material. At this time, the first gripper 32 and the second gripper 33 limit the material on the left and right sides, and the auxiliary plate 6 limits the material in the horizontal direction. This ensures that the material is not only subjected to the force of the grippers on both sides during the clamping process, but also to the support force of the top auxiliary plate 6. This prevents the material from shaking or slipping due to the shift of the center of gravity or external vibration during the handling process, and improves the stability after clamping.

[0042] When releasing material, the drive rod 41 drives the second screw to rotate in the opposite direction, and the auxiliary plate 6 rises along the axis of the drive rod 41. The rise of the auxiliary plate 6 increases the clamping space and prevents the auxiliary plate 6 from affecting the normal release of material.

[0043] The implementation principle of a clamping and handling device according to an embodiment of this application is as follows: When handling materials, the worker holds the housing 1 with one hand to restrict the rotation of the housing 1, and rotates the handle 2 in the forward direction with the other hand. The handle 2 drives the first threaded section 42 to rotate in the forward direction through the drive rod 41. Since the rotation of the housing 1 is restricted, the rotation of the first threaded section 42 drives the slider 43 to move upward along the axis of the drive rod 41. At this time, the angle between the first connecting rod 44 and the second connecting rod 45 and the axis of the drive rod 41 becomes smaller. The first connecting rod 44 and the second connecting rod 45 pull the first gripper 32 and the second gripper 33 to rotate in a direction that approaches each other. The two clamping plates 34 continuously approach each other and finally abut against the outer surface of the material to achieve clamping of the material.

[0044] After clamping, the worker holds handle 2 to lift housing 1 and transfer the material. Once the material reaches the designated location, the worker reverses the drive rod 41, causing the first threaded section 42 to rotate in the opposite direction. The slider 43 moves downward along the axis of drive rod 41, increasing the angle between the first connecting rod 44 and the second connecting rod 45 and the axis of drive rod 41. The first gripper 32 and the second gripper 33 drive the two clamping plates 34 to move away from each other. The two clamping plates 34 eventually detach from the material, and the material falls to the designated location. This design allows the operator to complete the material transfer operation without direct contact with the material, avoiding direct pressure on the hands from the sharp edges of the material, significantly reducing the risk of hand abrasions and fatigue, and thus improving the convenience for workers when handling materials.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
