[0031] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0032] As introduced in the background technology, the existing three-dimensional five-axis laser cutting machine is usually equipped with a large safety door structure. While this safety door protects the safety of the operator, it also brings many inconveniences. For example, the existing safety door structure is large in size, resulting in an increase in the overall footprint of the equipment, which is not conducive to the effective use of space. In order to solve the above technical problems, the utility model proposes a large surrounding lifting door structure.

[0033] like Figure 1 As shown, the large enclosed lifting door structure includes a fixing frame 1, an electric winch 2, a reversing pulley block and a wire rope 4. The fixing frame 1 includes a truss 11 and a mounting seat 13, and the mounting seat 13 is located on the upper side of the lifting door 62 (as shown in FIG. Figure 2 As shown), the truss 11 and the mounting seat 13 are located at the same height and are located behind the mounting seat 13; Figure 3 As shown, the electric winch 2 is installed on the truss 11. Figure 4 As shown, the reversing pulley block is mounted on the mounting seat 13 and is located at the left and right ends of the mounting seat 13; Figure 5As shown, the steel wire rope 4 includes a traction section 41, a separation section 42 and a lifting section 44. One end of the traction section 41 is wound on the electric winch 2, and the other end is connected to the two separation sections 42. The other end of the separation section 42 passes around the reversing pulley group and extends downward to form the lifting section 44. The lower end of the lifting section 44 is connected to the lifting door 62.

[0034] The driving part of the lifting door 62 is located at the top of the large enclosure 6 structure. After the steel wire rope 4 comes out of the electric winch 2, it first changes from one to two and then passes through the reversing pulley group to achieve two reversals. The lifting door 62 is connected from both sides of the top of the lifting door 62, and the lifting and lowering of the lifting door 62 is achieved by the forward and reverse rotation of the electric winch 2. The volume of the safety door is reduced, the space occupation of the equipment is reduced, the space utilization efficiency is improved, and it is suitable for equipment with a deeper longitudinal structure. In addition, the pulley group and the reversing function of one to two ensure the smooth lifting and lowering of the door body, which improves the convenience and safety of operation.

[0035] The design of changing the electric winch 2 and the steel wire rope 4 into two reduces the cost and the risk of twisting compared to the motor and the transmission shaft, and realizes fast and smooth lifting and lowering of the door body to meet the needs of frequent loading and unloading operations.

[0036] The lifting section 44 of the steel wire rope 4 is arranged vertically, and no directional force is generated, thereby reducing the risk of the lifting door 62 being deformed by the bias force, and reducing the cost of the guide structure of the lifting door 62.

[0037] like Figure 2 As shown, a crossbeam 61 is provided on the top of the large enclosure 6, and the truss 11 is installed in the middle position of the crossbeam 61 of the large enclosure 6. Figure 3 As shown, the truss 11 includes a support rod 111 and a fixing plate 112, the two ends of the support rod 111 are respectively mounted on the cross beam 61, the two ends of the fixing plate 112 are mounted on the support rods 111 on the left and right sides, and the electric winch 2 is mounted on the fixing plate 112. This structure ensures the stability and load-bearing capacity of the electric winch 2, and improves the rigidity and stability of the overall structure by reasonably distributing the positions of the support rods 111 and the fixing plate 112.

[0038] like Figure 3As shown, the rear end of the truss 11 is also provided with a guide pulley block 3, which includes a guide seat and a first guide wheel 31 and a second guide wheel 32 installed on the guide seat. The first guide wheel 31 includes a pair of guide wheels arranged horizontally, and the second guide wheel 32 includes a pair of guide wheels arranged vertically and front and back. After extending from the electric winch 2, the traction section 41 of the steel wire rope 4 passes through the pair of the first guide wheels 31, the front second guide wheel 32 and the rear second guide wheel 32 in sequence. The traction section 41 of the steel wire rope 4 is guided by the multiple guide wheels arranged horizontally and vertically in the guide pulley block 3, which effectively avoids the steel wire rope 4 from twisting and derailing during the transmission process, thereby improving the stability and transmission efficiency of the system.

[0039] like Figure 1 , Figure 3 As shown, the fixing frame 1 further includes a support frame 12, the front end of the support frame 12 is mounted on the rear side of the guide seat, and the rear end of the support frame 12 is mounted on the front side of the mounting seat 13. The support frame 12 provides additional support and stability, and the truss 11, the support frame 12 and the mounting seat 13 form an immutable rigid structure. This design can effectively share the load, especially during the lifting process of the door body, and further improves the safety and reliability of the system.

[0040] like Figure 4 As shown, the reversing pulley block includes a first reversing pulley block 5 and a second reversing pulley block 7, the second reversing pulley block 7 is located at the rear side of the first reversing pulley block 5, the separation section 42 bypasses the first reversing pulley block 5 to form a transition section 43, and the transition section 43 bypasses the second reversing pulley block 7 to form the lifting section 44. This multiple reversing design can effectively adjust the running track of the wire rope 4, ensure uniform force during the lifting and lowering of the door body, avoid the stress concentration problem caused by a single reversal, and form a transition section 43 between the two reversing pulley blocks to avoid close reversal on both sides, reduce the bending and wear of the wire rope 4, and improve the operating life of the system.

[0041] Specifically, the first reversing pulley set 5 includes a first reversing wheel 51 and a second reversing wheel 52, the first reversing wheel 51 includes a pair of reversing wheels arranged horizontally, the second reversing wheel 52 is arranged vertically and located in the middle of the two first reversing wheels 51 at the rear side of the first reversing wheel 51, the second reversing pulley set 7 includes a third reversing wheel 71, the third reversing wheel 71 is arranged vertically and aligned with the second reversing wheel 52, the starting end of the transition section 43 changes direction from the first reversing wheel 51 to the second reversing wheel 52, and the terminal changes direction again from the position of the third reversing wheel 71. Through this multi-level and multi-angle reversing pulley design, the wire rope 4 is smoothly converted in different directions and angles, ensuring the smooth operation of the lifting door 62.

[0042] like Figure 6 As shown, the top of the lifting door 62 is provided with a first lifting ring 622 and a second lifting ring 623, and the bottom of the lifting section 44 of the wire rope 4 is hung on the first lifting ring 622. Figure 8 As shown, an anti-falling rope 8 is provided at the bottom side of the mounting seat 13, and the bottom of the anti-falling rope 8 is hung on the second hanging ring 623. When the wire rope 4 breaks suddenly, the anti-falling rope 8 can prevent the door body from falling to the bottom and causing an accident, further improving the safety of the system.

[0043] like Figure 6 , Figure 7 As shown, guide wheels 621 are provided on the left and right sides of the lifting door 62, and vertically arranged guide grooves 63 are provided on both sides of the large enclosure 6, and the guide wheels 621 slide up and down in the guide grooves 63. By providing the guide wheels 621 and the guide grooves 63, it is ensured that the door body runs along the fixed track during the lifting process, avoiding the door body from being offset or tilted during the lifting process, and improving the stability and operation accuracy of the door body.

[0044] A bracket 64 is provided at the upper and lower ends of the side of the large enclosure 6, and a travel switch is installed on the bracket 64. The travel switch is used to detect the specific position of the lifting door 62, control the start and stop of the electric winch 2, ensure that the door body can be accurately positioned during the lifting process, avoid over-limit operation, and improve the automation degree and operation safety of the system.

[0045] Working principle:

[0046] The electric winch 2 fixed on the truss 11 drives the wire rope 4 to change direction through the pulley block. At the same time, the wire rope 4 is divided into two wire ropes 4. The two ends of the wire rope 4 are respectively connected to the first lifting ring 622. The first lifting ring 622 is installed on the left and right sides of the top of the lifting door 62 to balance the gravity exerted on the door body. The middle of the separated section 42 of the wire rope 4 is connected to the traction section 41 on the electric winch 2.

[0047] When the electric winch 2 receives the start signal, the winch rotates and drives the traction section 41 to roll up. At this time, it passes through the guide pulley block 3. The pulley block here deviates from the center line in order to ensure that the tensioning direction of the wire rope 4 is not affected by the motor winch. The traction section 41 of the wire rope 4 on the electric winch 2 is connected to the center of the separation section 42 of the wire rope 4, driving the separation section 42 to deform, gradually changing from a straight line to an acute angle. Then the separation section 42 of the wire rope 4 is reversed left and right and up and down through the reversing slide group, and the force is transmitted to the lifting door 62 to drive the lifting door 62 to move upward. When it moves to the position of the upper travel switch, the electric winch 2 receives a stop signal. At this time, the door body is opened to a distance of 1.75m, which can meet normal loading and unloading operations. After the loading and unloading operation is completed, a signal needs to be given manually to make the electric winch 2 rotate in the opposite direction and loosen the wire rope 4; thereby the lifting door 62 drops to the position of the lower travel switch. At this time, the limit switch sends a set of signals to stop the movement of the electric winch 2, completing one loading and unloading and door opening and closing operation of the three-dimensional five-axis cutting machine.

[0048] Based on the above large surrounding lifting door structure, the embodiment of the utility model also provides a three-dimensional five-axis cutting machine, in which the three-dimensional five-axis cutting machine is provided with the large surrounding lifting door structure described in the above embodiment. The door structure of the three-dimensional five-axis cutting machine is optimized, which significantly improves the space utilization and operation convenience of the equipment, while reducing the overall manufacturing cost and improving work efficiency and safety.

[0049] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
