Description

Technical Field

[0001] The present application relates to the technical field of stone processing equipment, and in particular to a lifting device for operating a large wire saw machine. Background Art

[0002] Stone cutting is a basic method of stone processing. Stone wire saw machine is a large-scale equipment for precise cutting of stone. When using stone wire saw machine, due to its large size, it is usually necessary to set up an operating platform around the wire saw machine for workers to stand on the operating platform to perform maintenance operations on the wire saw machine.

When in use, the staff climbs onto the operating platform via an escalator to perform maintenance operations on the wire saw machine. However, in actual use, the use of the above-mentioned fixed operating platform is not convenient for the staff to perform maintenance and repairs on different positions of the wire saw machine, and there is room for improvement. Utility Model Content

[0036] The embodiment of the present application discloses a lifting device for operating a large-scale wire saw machine.

[0037] Example 1:

[0038] Reference Figure 1 and Figure 2 A lifting device for operating a large wire saw machine includes a horizontally placed main frame 1, which is composed of several columns 11 and several beams 12. The several beams 12 are all located at the top of the columns 11, and the several beams 12 cooperate with each other to connect the tops of the several columns 11 together. In this embodiment, the columns 11 and the beams 12 are preferably set to four, and the four columns 11 and the four beams 12 form a rectangular frame structure. An accommodating space 13 is formed between the four columns 11, and a lifting platform 2 is provided on the outside of the columns 11.

[0039] Reference Figure 1 and Figure 2When in use, the column 11 and the beam 12 are assembled on the outside of the wire saw machine to ensure that the wire saw machine is located in the accommodating space 13, so that the wire saw machine and the inner wall of the lifting platform 2 are separated by a certain distance through the column 11 to ensure that the staff can perform maintenance operations on the wire saw machine without affecting the subsequent lifting of the lifting platform 2.

[0040] Reference Figure 1 and Figure 3 A driving assembly 3 and an auxiliary lifting assembly 4 are arranged between the main frame 1 and the lifting platform 2, wherein the driving assembly 3 is used to drive the lifting platform 2 to rise and fall in the vertical direction. The driving assembly 3 consists of a first rack 31, a first gear 32 and a driving structure 33. The first rack 31 is fixed to the column 11 by bolts, and the length direction of the first rack 31 is parallel to the height direction of the column 11. The first gear 32 is rotatably connected to the inner wall of the lifting platform 2, and the first gear 32 and the first rack 31 are meshed.

[0041] Reference Figure 1 and Figure 3 When in use, the first gear 32 is driven to rotate by the driving structure 33. Under the cooperation and guidance of the first rack 31, the first gear 32 rotates so that the first gear 32 itself rolls along the length direction of the first rack 31, thereby driving the lifting platform 2 to move up and down. In order to ensure the stability of the lifting process of the lifting platform 2, in this embodiment, two first gears 32 and two first racks 31 are provided, and the first gears 32 and the first racks 31 are provided one to one, and the two first gears 32 and the two first racks 31 are symmetrically provided at both ends of the width direction of the main frame 1.

[0042] Reference Figure 3 and Figure 4 The driving structure 33 includes a driving shaft 331, a driven sprocket 333, a driving sprocket 332, a chain 334 and a driving motor 335. The driving shaft 331 is rotatably connected to the lifting platform 2. The two first gears 32 are coaxially fixedly connected to the driving shaft 331, and the two first gears 32 are respectively located at both ends of the length direction of the driving shaft 331. The driven sprocket 333 is coaxially fixedly connected to the driving shaft 331. In this embodiment, the driven sprocket 333 is located between the two first gears 32, and the driving sprocket 332 is rotatably connected to the lifting platform 2. The chain 334 is wound between the driven sprocket 333 and the driving sprocket 332, and the chain 334 is meshed with the driven sprocket 333 and the driving sprocket 332.

[0043] Reference Figure 3 and Figure 4The driving motor 335 is installed on the lifting platform 2 by bolts, and the output shaft of the driving motor 335 is coaxially fixedly connected to the driving sprocket 332. In the present application, an installation cavity is provided on the lifting platform 2, and the driving motor 335 and the driving sprocket 332 are both arranged in the installation cavity. At the same time, a protective shell 6 is also provided on the lifting platform 2.

[0044] Reference Figure 3 and Figure 4 When in use, the driving motor 335 drives the driving sprocket 332 to rotate. Under the transmission action of the chain 334, the driving sprocket 332 rotates and synchronously drives the driven sprocket 333 to rotate. The driven sprocket 333 rotates and drives the driving shaft 331 to rotate, thereby driving the two first gears 32 to rotate synchronously, thereby driving the lifting platform 2 to rise and fall. In this process, the protective shell 6 protects the connection between the chain 334, the driving sprocket 332, the driven sprocket 333 and the driving shaft 331 to ensure the stability of the transmission process. At the same time, the driving sprocket 332, the driven sprocket 333 and the chain 334 are used for transmission, and the first gear 32 and the first rack 31 are engaged, so that the lifting control accuracy of the lifting platform 2 is higher and it is more convenient to use.

[0045] Reference Figure 1 and Figure 5 The auxiliary lifting assembly 4 is used to further ensure the stability of the lifting platform 2 during the lifting process. The auxiliary lifting assembly 4 is composed of a plurality of second racks 41 and a plurality of second gears 42.

The two second gears 42 are respectively provided at both ends of the linkage shaft 43 in the length direction, and the two second gears 42 are coaxially fixedly connected to the linkage shaft 43; when in use, during the lifting process of the lifting platform 2, the cooperation between the second gear 42 and the second rack 41 further ensures the stability of the lifting of the lifting platform 2.

[0047] Reference Figure 1 and Figure 6When in use, due to the gap between the inner side of the lifting platform 2 and the main frame 1, in the process of the first gear 32 and the first rack 31, the second gear 42 and the second rack 41 cooperating with each other, in order to prevent the first gear 32 and the second gear 42 from sliding laterally, causing the first gear 32 to disengage from the first rack 31 and the second gear 42 to disengage from the second rack 41, a guide rail 14 is also fixedly connected to the main frame 1 by bolts. In this embodiment, the guide rail 14 is provided with four guide rails 14, and the four guide rails 14 are respectively provided on a column 11, and the four guide rails 14 are symmetrically arranged in pairs.

[0048] Reference Figure 1 and Figure 6 , each guide rail 14 is slidably connected to a slide 15, and the slide 15 is fixedly connected to the lifting platform 2 by bolts, and in this embodiment, a corresponding avoidance groove for avoiding the first gear 32 or the second gear 42 is opened on the slide 15; when in use, through the coordinated use of the four guide rails 14 and the slide 15, the horizontal direction of the lifting platform 2 is limited without affecting the vertical lifting of the lifting platform 2, thereby ensuring the stability of the lifting platform 2 during use.

[0049] Reference Figure 1 A guardrail 7 is also fixedly connected to the surrounding side of the lifting platform 2, and an escalator 5 is provided on one side of the lifting platform 2. The escalator 5 is arranged in an inclined manner as a whole, and the top of the escalator 5 is fixedly connected to the lifting platform 2, and the bottom end of the escalator 5 is used to abut the ground. An entrance and exit are opened at the connection between the escalator 5 and the lifting platform 2, and the entrance and exit are used for staff to pass between the escalator 5 and the lifting platform 2; when in use, when the lifting platform 2 is in the lowest position, the bottom end of the escalator 5 abuts the ground. At this time, the staff can climb onto the lifting platform 2 through the escalator 5. During the lifting process of the lifting platform 2, the staff are protected by the guardrail 7 to ensure the safety of the staff during the maintenance process of the wire saw machine.

[0050] The implementation principle of the embodiment of the present application is: when in use, the main frame 1 is assembled on the outside of the wire saw machine, and the lifting platform 2 is assembled on the main frame 1; when the wire saw machine needs to be maintained, the staff can climb onto the lifting platform 2 through the escalator 5, and then under the action of the driving component 3, the lifting platform 2 is raised and lowered in the vertical direction, thereby driving the staff to move, so that the staff can perform maintenance operations on different positions of the wire saw machine. During the lifting process of the lifting platform 2, the cooperation of the guide rail 14 and the slide 15, as well as the action of the auxiliary lifting component 4, ensure the stability of the lifting platform 2 during use, and the protection of the protective net on the side of the lifting platform 2 ensures the safety of the staff walking on the lifting platform 2. The overall use is simple and convenient.
