[0041] Figure 1 Schematic diagram of the structure of the wedge assembly according to one embodiment of the present invention, as shown in FIG. Figure 1 As shown, and reference Figures 2 to 6 , an embodiment of the present utility model provides a wedge assembly.

[0042] The wedge assembly includes a first support block 100 , a second support block 200 , a fixed stopper 120 and a movable stopper 300 .

[0043] A slideway 110 extending along a first direction is provided on the top of the first support block 100 .

[0044] The second supporting block 200 is slidably disposed along the slideway 110 .

[0045] The fixed stopper 120 is fixedly connected to the first support block 100 and is stopped at one end of the slideway 110 .

[0046] The movable stopper 300 includes a connecting block 320 and a stop plate 310. The connecting block 320 is fixedly connected to one end of the first support block 100 away from the fixed stopper 120. The connecting block 320 is formed with a clearance groove 322 extending along a first direction so that the second support block 200 can be moved out of the slide 110 through the clearance groove 322. The connecting block 320 is also formed with a receiving groove 321 adjacent to the slide 110. The receiving groove 321 extends along a second direction perpendicular to the first direction and passes through the clearance groove 322. One end of the extending direction of the receiving groove 321 passes through the connecting block 320 to form a mounting opening 3221.

[0047] The stopping plate 310 is detachably inserted into the receiving groove 321 and stops at an end of the slideway 110 away from the fixed stopper 120 .

[0048] In this embodiment, when the cam assembly is in operation, the second support block 200 moves along the slideway 110, and the stop plate 310 is inserted into the receiving groove 321, stopping it on one side of the slideway 110. The stop plate 310 and the fixed stop block 120 are located at both ends of the slideway 110 to stop the second support block 200. When the cam assembly is in operation, the second support block 200 can only move along the slideway 110, preventing the second support block 200 from falling off the slideway 110.

[0049] When the cam assembly needs maintenance, the stop plate 310 is removed from the receiving groove 321, or the stop plate 310 is moved out of the clearance groove 322, so that when the second support block 200 moves in the first direction, the stop plate 310 does not stop the second support block 200, so that the second support block 200 can be moved out of the slide 110 through the clearance groove 322 and separated from the first support block 100. When the cam assembly of the present invention is switched from a working state to a maintenance state, there is no need to remove bolts or other fastening components before removing the movable stop block 300 of the cam assembly. Instead, the stop plate 310 only needs to be removed from the receiving groove 321 to remove the second support block 200 from the slide 110, thereby achieving disassembly of the cam assembly. This simplifies the operation of disassembling the cam assembly, saves time for disassembling the cam assembly, and thus achieves the purpose of improving the maintenance efficiency of the cam assembly.

[0050] The stop plate 310 is slidably connected to the accommodating groove 321, and the movement of the stop plate 310 is limited by the accommodating groove 321, which not only provides a guide for the movement of the stop plate 310 to prevent the stop plate 310 from deviating, but also limits the stop plate 310 to improve the stability of the stop plate 310 during the sliding process.

[0051] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the receiving groove 321 is horizontally arranged so that the receiving groove 321 passes through one lateral side of the connecting block 320 .

[0052] In this embodiment, the receiving groove 321 extends horizontally, meaning the second direction is horizontal, so that the mounting opening 3221 is located at one horizontal end of the stopper 310. The stopper 310 is inserted into the receiving groove 321 through the mounting opening 3221. Since the receiving groove 321 is horizontally disposed and the stopper 310 slides within the receiving groove 321 along the second direction, meaning the stopper 310 is horizontally disposed, the receiving groove 321 supports the horizontally disposed stopper 310 upward, preventing the stopper 310 from sliding out of the receiving groove 321 when the receiving groove 321 is tilted downward and the mounting opening 3221 is not obstructed, thereby improving the installation stability of the stopper 310.

[0053] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the movable stopper 300 further includes a stopper post 350 and a stopper groove 360 ​​provided on the stopper plate 310. The stopper post 350 passes through the connecting block 320 and is movably inserted into the stopper groove 360 ​​to limit the stopper plate 310 from moving along the second direction.

[0054] In this embodiment, the stop post 350 is inserted into the stop slot 360 to restrict the movement of the stop plate 310 in the second direction. When the stop plate 310 needs to be installed or removed, the stop post 350 is removed from the stop slot 360, allowing the stop plate 310 to be inserted into or removed from the receiving slot 321 through the installation opening 3221. When the cam assembly is in operation, the stop plate 310 is located in the receiving slot 321, and the stop post 350 is inserted into the stop slot 360, preventing the stop plate 310 from falling out of the installation opening 3221. This prevents the cam assembly from posing a safety hazard due to the stop plate 310 falling out.

[0055] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the stopping groove 360 ​​is disposed on a side of the stopping plate 310 away from the slideway 110 .

[0056] In this embodiment, the stopping column 350 passes through the side of the connecting block 320 away from the slide 110 and is inserted into the stopping groove 360. There is interference between the side groove wall of the stopping groove 360 ​​away from the installation port 3221 and the stopping column 350 to prevent the stopping plate 310 from slipping from the installation port 3221.

[0057] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the movable stopper 300 further includes a first handle 400, which is fixedly connected to the stopper column 350 and is arranged perpendicular to the moving direction of the stopper column 350. The position of the stopper column 350 can be changed by pushing the first handle 400.

[0058] In some embodiments of the present invention, Figure 6 As shown, the movable stopper 300 further includes a first elastic member 340 . The first elastic member 340 is configured to force the stopping post 350 to be inserted into the stopping groove 360 ​​.

[0059] In this embodiment, when switching from a maintenance state to an operating state, the second support block 200 is first installed on the slideway 110 through the clearance groove 322, and the stopper column 350 is then inserted into the stopper groove 360. The external force applied to the stopper column 350 is then removed, so that the first elastic member 340 is subjected to a restoring force that moves the stopper column 350 until it is inserted into the stopper groove 360, thereby preventing the stopper plate 310 from falling out of the receiving groove 321, thereby completing the assembly of the cam assembly. This cam assembly does not require disassembly or assembly of the cam assembly by removing or installing screws, thereby simplifying the operation of assembling the cam assembly after maintenance and improving the assembly efficiency of the cam assembly.

[0060] In some embodiments of the present invention, Figure 6 As shown, the first elastic member 340 is a telescopic spring.

[0061] In some embodiments of the present invention, the movable stopper 300 further includes a movable plate, which is movably disposed at the installation opening 3221 to stop at the installation opening 3221 .

[0062] In this embodiment, the opening and closing of the mounting opening 3221 are controlled by moving the position of a movable plate. To install or remove the stop plate 310, the movable plate is moved to the outer periphery of the mounting opening 3221, allowing the stop plate 310 to be inserted into or removed from the receiving slot 321 through the mounting opening 3221. When the cam assembly is in operation, the stop plate 310 is located within the receiving slot 321, and the movable plate is retained by the mounting opening 3221, preventing the stop plate 310 from falling out of the mounting opening 3221. This, in turn, avoids potential safety hazards to the cam assembly caused by the stop plate 310 falling out.

[0063] In some embodiments of the present invention, the movable plate is slidably connected to a side of the connecting block 320 where the mounting opening 3221 is provided.

[0064] In some embodiments of the present invention, the movable plate is rotatably connected around the rotation axis to a surface of the first support block 100 where the mounting opening 3221 is provided.

[0065] The movable stopper 300 further includes a second elastic member configured to force the movable plate to stop at the installation opening 3221 .

[0066] In this embodiment, when switching from a maintenance state to an operating state, the second support block 200 is first installed on the slideway 110 through the clearance groove 322, and the stop plate 310 is then inserted into the receiving groove 321. The external force applied to the movable plate is then removed, so that the second elastic member is subjected to a restoring force that moves the movable plate to the side that is stopped by the installation opening 3221, thereby preventing the stop plate 310 from falling out of the receiving groove 321, thereby completing the assembly of the cam assembly. This cam assembly does not require the disassembly or assembly of the cam assembly by removing or installing screws, simplifying the operation of assembling the cam assembly after maintenance and improving the assembly efficiency of the cam assembly.

[0067] In some embodiments of the present invention, the second elastic member is a torsion spring.

[0068] In this embodiment, a torsion spring is mounted on a rotating shaft fixedly connected to the movable plate. One end is fixedly connected to the rotating shaft, and the other end is fixedly connected to the first support block 100. This allows the torsion spring to rotate with the rotation of the movable plate. When the movable plate is not subjected to external forces, the restoring force of the torsion spring causes the movable plate to move to the stop position. Furthermore, the torsion spring is relatively inexpensive to manufacture and easy to maintain and replace, reducing the manufacturing and maintenance costs of the cam assembly.

[0069] In some embodiments of the present invention, the movable stopper 300 further includes a second handle, which is fixedly connected to an end of the movable plate away from the rotation axis.

[0070] In this embodiment, the second handle is fixedly connected to the movable plate. When the angled wedge assembly needs to be disassembled, the second handle can be moved to move the movable plate to the disassembly position. Positioning the second handle at the end of the movable plate away from the rotation axis reduces the force applied when moving the second handle, making movement of the movable plate easier, thereby facilitating removal of the stop plate 310 and simplifying disassembly of the angled wedge assembly.

[0071] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the connecting block 320 further includes a guide block 324 , the upper surface of which forms the lower groove wall of the accommodating groove 321 , and the upper surface of the guide block 324 is in the same plane as the upper surface of the first supporting block 100 .

[0072] In this embodiment, the guide block 324 not only supports the stopping plate 310 but also guides the stopping plate 310 when it is inserted into the receiving groove 321 .

[0073] The guide block 324 is flush with the upper surface of the first support block 100. This prevents interference between the guide block 324 and the second support block 200 when the wedge assembly is disassembled in the first direction, thereby facilitating the removal of the second support block 200 from the slideway 110 and separation from the first support block 100. Furthermore, compared to a case where the upper surface of the guide block 324 is positioned below the upper surface of the first support block 100, the flush positioning of the guide block 324 with the upper surface of the first support block 100 increases the contact area between the connecting block 320 and the first support block 100, thereby making the connection of the connecting block 320 more stable, and thereby making the connection of the movable stopper 300 more stable.

[0074] In some embodiments of the present invention, Figure 5 As shown, a plurality of first connection holes 323 are provided on the connection block 320 , and a second connection hole corresponding to the plurality of first connection holes 323 is provided on the first support block 100 .

[0075] In this embodiment, the connecting block 320 is fastened to the first support block 100 via bolts. The bolts are sequentially inserted into the first and second connecting holes 323 to securely connect the connecting block 320 to the first support block 100. Bolted connections are convenient and inexpensive, allowing for straightforward replacement if damaged, reducing the manufacturing and maintenance costs of the cam assembly.

[0076] Of course, the connecting block 320 can also be fastened to the first supporting block 100 by other fasteners such as pins.

[0077] Alternatively, the connecting block 320 may also be welded to the first supporting block 100 .

[0078] In some embodiments of the present invention, Figure 5 As shown, there are four first connection holes 323 , which are evenly spaced and evenly distributed on both sides of the clearance slot 322 .

[0079] In this embodiment, the four connection holes are evenly spaced on the connection block 320, so that the connection between the connection block 320 and the first support block 100 is evenly stressed, balancing the stress on the connection block 320, avoiding damage caused by uneven stress on the connection block 320, and improving the connection stability between the connection block 320 and the first support block 100.

[0080] The first connection holes 323 are evenly spaced on both sides of the clearance slot 322 to prevent interference between the clearance slot 322 and the first connection holes 323. Preferably, the clearance slot 322 is located in the center of the connecting block 320, that is, the receiving slot 321 is located in the middle of the connecting block 320. This ensures that the wall thicknesses on both sides of the receiving slot 321 are equal, thereby improving the structural strength of the receiving slot 321 and, in turn, the stability of the stopper 310. The placement of the first connection holes 323 on both sides of the clearance slot 322 further stabilizes the connection between the connecting block 320 and the first support block 100.

[0081] In some embodiments of the present invention, the slideway 110 is parallel to the upper surface of the first support block 100 .

[0082] In this embodiment, the slideway 110 is parallel to the upper surface of the first support block 100, thereby preventing the second support block 200 from interfering with the first support block 100 during the sliding process. The second support block 200 is slidably disposed on the upper surface of the first support block 100, and the slideway 110 is parallel to the upper surface of the first support block 100, which further stabilizes the structure of the slideway 110 and improves the support effect of the first support block 100 on the second support block 200.

[0083] In some embodiments of the present invention, Figure 1 As shown, a surface of the stop plate 310 facing the second support block 200 is parallel to a surface of the second support block 200 facing the stop plate 310 .

[0084] In this embodiment, the side of the stop plate 310 and the second support block 200 that are close to each other are arranged in parallel, so that the stop plate 310 and the second support block 200 are subjected to uniform force when in contact, avoiding deformation or damage due to uneven force on the side of the stop plate 310 and the second support block 200 that are close to each other, thereby improving the service life of the wedge assembly.

[0085] In some embodiments of the present invention, Figure 1 As shown, the connection surface between the first support block 100 and the movable stopper 300 is arranged perpendicular to the slideway 110 .

[0086] In some embodiments of the present invention, Figure 2 As shown, the first support block 100 further includes two guide blocks 111 disposed opposite each other. The two guide blocks 111 are disposed on either side of the first support block 100, forming a slideway 110 between the two guide blocks 111. A slider is formed at the bottom of the second support block 200. The slider is slidably disposed between the two guide blocks 111 and is slidably connected to the guide blocks 111.

[0087] In this embodiment, two guide blocks 111 are respectively provided on either side of the first support block 100 to form a slideway 110. A slider at the lower end of the second support block 200 is slidably engaged with the slideway 110. The guide blocks 111 provide guidance and support for the sliding of the second support block 200, allowing the second support block 200 to slide along the slideway 110.

[0088] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
