[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] like Figures 1 to 5 As shown, the present invention provides a cutting device with a lifting guardrail, comprising:

[0041] The frame 100 serves as the supporting structure for the guardrail;

[0042] A power source 200 is mounted on a frame 100. The output direction of the power source 200 is horizontal, and a connector 210 is connected to the output end of the power source 200. The power source 200 drives the connector 210 to reciprocate in the horizontal direction. The connector 210 is provided with a first clamping part 211 and a second clamping part 212. The first clamping part 211 and the second clamping part 212 are arranged vertically along the moving direction perpendicular to the connector 210.

[0043] Two pulley assemblies are connected to the frame 100, namely a first pulley assembly 300 and a second pulley assembly 320 400, and the first pulley assembly 300 and the second pulley assembly 320 400 are located at opposite ends along the moving direction of the connector 210.

[0044] A pull rope 500 has one end connected to the first clamping part 211, and the other end passes sequentially around the first pulley assembly 300 and the second pulley 320 assembly 400, and is connected to the second clamping part 212. The pull rope 500 is arranged in a U-shape, and the connector 210 is located at the closed end of the U-shaped pull rope 500. The first pulley assembly 300 and the second pulley 320 assembly 400 are respectively located on both sides of the open end of the U-shaped pull rope 500.

[0045] The guardrail assembly 600 is connected to the pull rope 500 on both sides along the moving direction of the connector 210 via a first fixing part 610 and a second fixing part 620, respectively. The first fixing part 610 and the second fixing part 620 are located on both sides of the open end of the U-shaped pull rope 500. The guardrail assembly 600 can be raised and lowered synchronously on both sides along the moving direction of the connector 210 by the reciprocating movement of the connector 210.

[0046] This utility model provides a cutting device with a lifting guardrail. Through a single power source 200, combined with a pulley assembly and a pull rope 500, the synchronicity of the lifting and lowering of both sides of the guardrail assembly 600 is achieved. Moreover, the selection of the power source 200 only needs to be able to overcome the gravity of the guardrail assembly 600, thereby reducing the production cost of the cutting device.

[0047] More preferably, the first clamping part 211 and the second clamping part 212 are staggered along the moving direction perpendicular to the connector 210.

[0048] It is worth mentioning that the first clamping part 211 and the second clamping part 212 are staggered, which provides space for the first guide part 213 and the second guide part 214. Furthermore, the arrangement of the first guide part 213 and the second guide part 214 ensures that one end of the pull rope 500 output from the first pulley assembly 300 and one end of the pull rope 500 entering the second pulley 320 assembly 400 are on the same horizontal plane, thereby further ensuring the synchronicity of the lifting and lowering of both sides of the guardrail assembly 600.

[0049] It is further pointed out that the first guide portion 213 and the second guide portion 214 are both rollers, and the rollers are connected to the connector 210 by fasteners. The first guide portion 213 and the second guide portion 214 are both tangential to the edge of the roller.

The center of the third pulley 330 in the first pulley assembly 300 and the center of the first pulley 310 in the second pulley assembly 320 are on the same horizontal plane. The horizontal and vertical distance between the centers of the first pulley 310 and the third pulley 330 is the same as the diameter of the second pulley 320.

[0052] In this embodiment, since the horizontal and vertical distance between the center of the first pulley 310 and the center of the third pulley 330 is the same as the diameter of the second pulley 320, when a first tangent point is provided between the pull rope 500 and the first pulley 310, a second tangent point and a third tangent point are provided between the pull rope 500 and the second pulley 320, and a fourth tangent point is provided between the pull rope 500 and the third pulley 330, the line connecting the first tangent point and the second tangent point and the line connecting the third tangent point and the fourth tangent point are parallel to each other, thereby ensuring that the two sides of the guardrail assembly 600 maintain their corresponding verticality when they are raised and lowered synchronously, thereby improving the reliability of the raising and lowering of the guardrail assembly 600.

[0053] It is further pointed out that the center of the first pulley 310 and the center of the second pulley 320 are in the same vertical plane.

[0054] It is further pointed out that the diameters of the first pulley 310, the second pulley 320, and the third pulley 330 are the same, and the diameter of the first pulley 310 in the first pulley assembly 300 is the same as the diameter of the first pulley 310 in the second pulley assembly 400, the diameter of the second pulley 320 in the first pulley assembly 300 is the same as the diameter of the second pulley 320 in the second pulley assembly 400, and the diameter of the third pulley 330 in the first pulley assembly 300 is the same as the diameter of the third pulley 330 in the second pulley assembly 400.

On the one hand, this can improve the efficiency of the cutting equipment assembly, and on the other hand, it can reduce the types of pulleys and facilitate management.

[0056] Preferably, the first pulley assembly 300 further includes a support column 340, which is connected to the frame 100 by fasteners. The length direction of the support column 340 is consistent with the lifting direction of the guardrail assembly 600.

The first pulley 310 and the third pulley 330 are staggered vertically along the lifting direction of the guardrail assembly 600.

[0057] Preferably, the guardrail assembly 600 is provided with sliding components on both sides of the corresponding support column 340 along the moving direction of the connector 210, namely a first sliding component 700 and a second sliding component 800.

One side of the second sliding component 800 is connected to the support column 340 in the second pulley assembly 320, and the other side of the second sliding component 800 is connected to the corresponding side on the guardrail assembly 600. The first sliding component 700 and the second sliding component 800 enable the two sides of the guardrail assembly 600 to slide relative to the corresponding support column 340.

[0058] It is worth mentioning that by setting the first sliding component 700 and the second sliding component 800, the smoothness and verticality of the guardrail component 600 during the lifting and lowering process are improved.

[0059] Preferably, the first sliding component 700 and the second sliding component 800 have the same structure. For ease of description, the first sliding component 700 will be used as an example.

[0061] It is worth mentioning that, since the guardrail assembly 600 has a large area in the vertical plane, in order to prevent the guardrail assembly 600 from deflecting when it rises and falls in the vertical plane, there are two first sliders 720, and both first sliders 720 are slidably connected to the first slide rail 710. The two first sliders 720 are connected to the first slider mounting block 730.

[0062] Preferably, a limiting structure 350 is provided on the support column 340. The limiting structure 350 includes an upper limiting part 351 and a lower limiting part 352, and the upper limiting part 351 and the lower limiting part 352 are arranged vertically along the lifting direction of the guardrail assembly 600. The guardrail assembly 600 is provided with a limiting block 630 that cooperates with the upper limiting part 351 and the lower limiting part 352, and the limiting block 630 is located between the upper limiting part 351 and the lower limiting part 352. The lifting stroke of the guardrail assembly 600 is controlled by the cooperation between the upper limiting part 351, the lower limiting part 352 and the limiting block 630.

[0063] Preferably, the power source 200 is a cylinder, which is connected to the frame 100 via a cylinder mounting plate 220. The connector 210 includes a first cylinder connecting plate 215 and a second cylinder connecting plate 216 connected to each other. The first cylinder connecting plate 215 is connected to the output end of the power source 200. A first clamping part 211 and a second clamping part 212 are disposed on the second cylinder connecting plate 216. A sliding structure 230 is provided between the second cylinder connecting plate 216 and the cylinder mounting plate 220 to ensure the straightness of the power source 200 when driving the connector 210 to move.

[0064] It is worth mentioning that the sliding structure 230 includes a second slide rail 231 connected to the cylinder mounting plate 220, and a second slider 232 slidably connected to the second slide rail 231, wherein the second slider 232 is connected to the second cylinder connecting plate 216.

[0065] More preferably, a horizontal limiting part 240 is provided on the cylinder mounting plate 220, and the horizontal limiting part 240 is disposed opposite to the output end of the power source 200. The maximum extension stroke of the output end of the power source 200 is controlled by the horizontal limiting part 240, thereby controlling the maximum unidirectional movement stroke of the connecting member 210 in the horizontal direction.

[0066] Preferably, the guardrail assembly 600 includes a guardrail bracket 640 and a guard plate 650 connected to the guardrail bracket 640, and the guard plate 650 is made of a transparent material, such as glass. One end of the first fixing part 610 and the second fixing part 620 is connected to the guardrail bracket 640, and the other end of the first fixing part 610 and the second fixing part 620 is connected to the pull rope 500.

[0067] In this embodiment, the protective plate 650 is made into a transparent structure, so that the operator can see the current cutting situation through the protective plate 650. If an abnormality is found, the cutting equipment can be shut down in time to avoid waste of materials.

[0068] More preferably, light curtain support frames 660 are connected to both sides of the support plate 650 along the moving direction of the connector 210, and safety light curtain 670 is connected to the light curtain support frame 660.

[0069] It is worth mentioning that a liftable guardrail assembly 600 is installed on both sides of the cutting equipment. The safety light curtain 670 on one guardrail assembly 600 is the signal transmitter, and the safety light curtain 670 on the other guardrail assembly 600 is the signal receiver. When an object (such as a hand or body) enters the area between the signal transmitter and the signal receiver, it will be triggered, and the cutting equipment will be shut down directly, thus achieving the effect of safety protection.
