Each clamp assembly comprises two pull rods hinged to the upper crossbeam, and two curved arms hinged to the two pull rods, the curved arms being connected to the lower crossbeam. One curved arm of the clamp assembly is provided with jaws disposed toward the other curved arm thereof, and the clamp assembly is provided with a jaw adjustment mechanism for adjusting the distance between the jaws and the other curved arm of the clamp assembly. The adjustment process of the device is simple and convenient. For trapezoidal slabs of different widths, the jaws can be adjusted to enable the clamp assembly to clamp the trapezoidal slab. This avoids the problems of low thickness accuracy and difficulty in manufacturing manually placed steel plates. For trapezoidal slabs of different sizes, only the jaws need to be adjusted, making the operation convenient and easy. After the alignment of the material is completed, the rotary shutter needs to be manually controlled to drive the two curved arms to clamp the material, resulting in a low level of intelligence.

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] In order to solve the technical problem that the device has a low degree of intelligence due to the need for manual control of the rotary switch to drive the two curved arms to clamp the material 1 after the alignment of the material 1 is completed, the utility model provides a trapezoidal slab mechanical clamp, which can achieve that after driving the positioning block 21 and the sliding member 4 to abut against the material 1, the positioning block 21 is continued to be driven to make the material 1 slide relative to the positioning block 21. When the sliding member 4 and the material 1 are abutted against the touch switch 3, the touch switch 3 automatically triggers the driving member 23, so that the two clamping members 22 rotate relative to the positioning block 21 and clamp the material 1. There is no need for the user to manually control the positioning block 21 to slide close to the material 1 and control the driving member 23 to start, which can realize the intelligence of the device and facilitate operation.

[0044] It should be noted that the mechanical clamp for trapezoidal slabs described in the present invention is used for but not limited to the field of lifting equipment technology, etc. For the sake of convenience, in the present invention, only the application of the mechanical clamp for trapezoidal slabs in the field of lifting equipment technology is used as an example for explanation, and the principle of applying the mechanical clamp for trapezoidal slabs to other types of equipment is essentially the same as the principle applied to the field of lifting equipment technology, which will not be repeated here.

[0045] See also Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a mechanical clamp for a trapezoidal slab in an embodiment of the present invention. The mechanical clamp for a trapezoidal slab is used to clamp a material 1, and includes: a clamping assembly 2, a touch switch 3 and a sliding member 4. The clamping assembly 2 includes a positioning block 21, two clamping members 22 and a driving member 23. The two clamping members 22 are respectively hinged to the positioning block 21. The driving member 23 is hinged to the two clamping members 22 and is used to drive the two clamping members 22 to rotate closer to or away from each other to clamp or release the material 1. The touch switch 3 is connected to the positioning block 21 and is electrically connected to the driving member 23. The sliding member 4 is arranged relative to the touch switch 3 and is slidably connected to the positioning block 21. The sliding member 4 can slide with the material 1 and abut against the touch switch 3 to start the driving member 23.

[0046] In this device, two clamping members 22 are relatively arranged on both sides of the material 1 and are respectively hinged to the positioning block 21. Driven by the driving member 23, the two clamping members 22 can rotate closer to or away from the positioning block 21 and the material 1 to clamp or release the material 1. The positioning block 21 is also provided with a touch switch 3 electrically connected to the driving member 23. The sliding member 4 is arranged relative to the touch switch 3 and is slidably connected to the positioning block 21. After the sliding member 4 abuts against the material 1, it can slide close to the touch switch 3 along with the material 1 to abut against the touch switch 3, thereby starting the driving member 23 to drive the two clamping members 22 to clamp the material 1.

[0047] Compared with the prior art, after driving the positioning block 21 and the sliding member 4 to abut against the material 1, the user continues to drive the positioning block 21 to make the material 1 slide relative to the positioning block 21. When the sliding member 4 and the material 1 abut against the touch switch 3, the touch switch 3 automatically triggers the driving member 23, so that the two clamping members 22 rotate relative to the positioning block 21 and clamp the material 1. There is no need for the user to manually control the positioning block 21 to slide close to the material 1 and control the driving member 23 to start. The device can be intelligent, easy to operate, and improve production efficiency. It can solve the technical problem in the prior art that after completing the alignment of the material 1, manual control of the rotary switch is still required to drive the two curved arms to clamp the material 1, resulting in a low degree of intelligence of the device.

[0048] Specifically, the driving member 23 in this device is a scissor-type telescopic structure, which is hinged to the two clamping members 22 respectively. The rotation of the two clamping members 22 relative to the positioning block 21 can be achieved through the extension or shortening of the scissor-type telescopic structure. This is a conventional setting known to those skilled in the art.

[0049] Furthermore, the positioning block 21 is trapezoidal, and the cross-sectional area of ​​the positioning block 21 gradually decreases in the direction approaching the material 1. The positioning block 21 here belongs to a conventional setting well known to those skilled in the art and will not be described in detail here.

[0050] In this embodiment, the clamping member 22 includes a clamping arm 221, a first clamp head 222 and a second clamp head 223, and the sliding member 4 includes a sliding plate 41 and at least one sliding rod 42, at least one first elastic part 43, at least two rollers 44, and at least one second elastic part 45.

[0051] In one embodiment, see Figure 3 The positioning block 21 has at least one guide groove relative to the material 1, the sliding plate 41 is arranged between the positioning block 21 and the material 1, the sliding rod 42 is arranged in a one-to-one correspondence with the guide groove, one end of the sliding rod 42 is connected to the sliding plate 41, and the other end is slidably inserted into the guide groove.

[0052] The sliding cooperation between the sliding rod 42 and the guide groove plays a role in sliding connection between the sliding plate 41 and the positioning block 21 .

[0053] As a preferred embodiment, Figure 3 As shown, the sliding member 4 includes a plurality of sliding rods 42 , which are distributed at intervals along the surface of the positioning block 21 .

[0054] The plurality of sliding rods 42 are distributed at intervals and are all connected to the sliding plate 41 to improve the stability of the sliding connection.

[0055] In one embodiment, see Figure 3 One end of the first elastic portion 43 is connected to the positioning block 21 , and the other end is connected to the sliding plate 41 , and is used to drive the sliding plate 41 to slide relative to the positioning block 21 and then automatically reset.

[0056] The elastic restoring force generated by the first elastic portion 43 can abut against a portion of the thrust that pushes the sliding rod 42 to slide relative to the positioning block 21, thereby preventing abnormal operation of the device caused by misoperation.

[0057] Furthermore, the first elastic part 43 here is a spring, elastic block or spring piece that is common and easy to purchase on the market. The first elastic part 43 here belongs to a conventional setting well known to those skilled in the art and will not be described in detail here.

[0058] In one embodiment, see Figure 1 、 Figure 3 At least two rollers 44 are spaced apart from each other and are both rotatably connected to the sliding plate 41 , and the rollers 44 can abut against the surface of the material 1 .

[0059] By arranging the roller 44 to abut against the surface of the material 1 , damage to the surface of the material 1 caused by the rigid contact between the sliding plate 41 and the surface of the material 1 is avoided.

[0060] Furthermore, the roller 44 here is a conventional setting well known to those skilled in the art and will not be described in detail here.

[0061] In one embodiment, see Figure 3 The positioning block 21 is further provided with a receiving groove, which is connected to at least one guide groove. The touch switch 3 is built into the receiving groove and is connected to the sliding track of the other end of the sliding rod 42.

[0062] The touch switch 3 is arranged on the sliding track at the other end of the sliding rod 42 and is built into the receiving groove, which can avoid the safety hazards caused by accidental touch and improve the overall appearance of the device.

[0063] In one embodiment, see Figure 3 The touch switch 3 includes an electrical control end 31 and an electrical contact end 32. The electrical control end 31 and the electrical contact end 32 of the touch switch 3 are electrically connected to the driving member 23 respectively, and the electrical control end 31 and the electrical contact end 32 of the touch switch 3 are flexibly connected. After sliding, the other end of the sliding rod 42 can abut against the electrical contact end 32 of the touch switch 3, thereby making the electrical control end 31 and the electrical contact end 32 of the touch switch 3 electrically conductive.

[0064] The electrical control end 31 and the electrical contact end 32 of the touch switch 3 are electrically connected to the driving member 23 respectively. By abutting or separating the other end of the sliding rod 42 with the electrical contact end 32 of the touch switch 3, the electrical control end 31 and the electrical contact end 32 of the touch switch 3 are turned on or off, thereby realizing electrical control of the driving member 23 and achieving electrical control drive of the two clamping members 22.

[0065] Furthermore, the touch switch 3 here is a common and easily purchased device on the market. It is a conventional setting well known to those skilled in the art and will not be described in detail here.

[0066] In one embodiment, see Figure 3 The second elastic portion 45 is disposed between the touch switch 3 and the bottom inner wall of the receiving groove, and both ends of the second elastic portion 45 are connected to the touch switch 3 and the bottom inner wall of the receiving groove respectively.

[0067] The second elastic portion 45 is arranged between the touch switch 3 and the bottom inner wall of the accommodating groove, so that even after the material 1 pushes the sliding rod 42 to abut against the touch switch 3, it can continue to push the touch switch 3 to slide, thereby avoiding damage to the touch switch 3.

[0068] Furthermore, the second elastic part 45 here is a spring, elastic block or spring sheet that is common and easy to purchase on the market. The second elastic part 45 here belongs to a conventional setting well known to those skilled in the art and will not be described in detail here.

[0069] In this embodiment, Figure 1 、 Figure 2 As shown, the two clamping arms 221 are arranged opposite to each other and are rotatably connected to the two sides of the positioning block 21 respectively. The two first clamp heads 222 are respectively arranged opposite to the material 1 and are respectively detachably connected to the clamping arms 221.

[0070] The first clamp head 222 is detachably connected to the clamping arm 221 , so that the user can make a reasonable selection according to the materials 1 of different sizes.

[0071] Specifically, the first clamp head 222 has a clamp head abutting end and a connecting end. The clamp head abutting end of the first clamp head 222 is tightly pressed against the surface of the material 1 , and the connecting end of the first clamp head 222 is detachably connected to the clamping arm 221 .

[0072] In one embodiment, see Figure 2 The second clamp head 223 is arranged between the clamping arm 221 and the first clamp head 222 , and one end of the second clamp head 223 is detachably connected to the clamping arm 221 , and the other end is clamped to the first clamp head 222 .

[0073] The second clamp head 223 is made of a different material from the first clamp head 222 , is disposed between the clamp arm 221 and the connecting end of the first clamp head 222 , and is detachably connected to the clamp arm 221 and the connecting end of the first clamp head 222 .

[0074] Specifically, the clamping arm 221 is provided with a first threaded hole, the second clamp head 223 is provided with a first through hole relative to the first threaded hole, the threaded section of the fastening connection part passes through the first through hole and is threadedly connected to the first threaded hole, the clamping arm 221 is also provided with a second threaded hole, the second clamp head 223 is further provided with a wedge-shaped groove on the side relative to the first clamp head 222, and the bottom inner wall of the wedge-shaped groove is provided with a second through hole relative to the second threaded hole, the first clamp head 222 is provided with a third through hole relative to the second through hole, the threaded section of the fastening connection part passes through the third through hole and the second through hole in sequence, and is threadedly connected to the second threaded hole.

[0075] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0076] The two clamping members 22 are relatively arranged on both sides of the material 1 and are respectively hinged to the positioning block 21. Driven by the driving member 23, the two clamping members 22 can rotate closer to or away from the positioning block 21 and the material 1 to clamp or release the material 1. The positioning block 21 is also provided with a touch switch 3 electrically connected to the driving member 23. The sliding member 4 is arranged relative to the touch switch 3 and is slidably connected to the positioning block 21. After the sliding member 4 abuts against the material 1, it can slide close to the touch switch 3 along with the material 1 to abut against the touch switch 3, thereby starting the driving member 23 to drive the two clamping members 22 to clamp the material 1. Compared with the prior art, after driving the positioning block 21 and the sliding member 4 to abut against the material 1, the user continues to drive the positioning block 21 to make the material 1 slide relative to the positioning block 21. When the sliding member 4 and the material 1 abut against the touch switch 3, the touch switch 3 automatically triggers the driving member 23, so that the two clamping members 22 rotate relative to the positioning block 21 and clamp the material 1. There is no need for the user to manually control the positioning block 21 to slide close to the material 1 and control the driving member 23 to start, which can realize the intelligence of the device, facilitate operation, and improve production efficiency.

[0077] The specific working process of the present invention is that when in use, the user first moves the positioning block 21 so that the positioning block 21 is set relative to the material 1, and the two clamping arms 221 are located on both sides of the material 1, and then pushes the positioning block 21 to slide close to the material 1 until at least two rollers 44 abut against the surface of the material 1, and then continues to push the positioning block 21, and the material 1 drives the rollers 44 and the sliding rod 42 to slide close to the electric contact end 32 of the touch switch 3, and abuts against the electric contact end 32 of the touch switch 3, so that the driving member 23 is started, and finally, driven by the driving member 23, the clamping arms 221 on both sides rotate close to each other to clamp the material 1.

[0078] Furthermore, the user controls the driving member 23 to move in the reverse direction to drive the two clamping arms 221 to rotate in directions away from each other, thereby releasing the two clamping arms 221 from clamping and tightening the material 1 .

[0079] The above structure of the device can solve the technical problem in the prior art that after the alignment of the material 1 is completed, the manual control of the rotary shutter is still required to drive the two curved arms to clamp the material 1, resulting in a low level of intelligence of the device.

[0080] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention.
