Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, specifically to a new type of sliding door with a multi-wire saw cover. Background Technology

[0002] Multi-wire saws are widely used in stone quarrying, building demolition, and mining. They cut materials such as stone or concrete using a high-speed diamond saw wire. In recent years, with the development of industries like construction and mining, the use of multi-wire saws has become increasingly common. During operation, the diamond saw wire generates cutting debris at high speeds, and there is a risk of wire breakage. If the saw wire breaks, it can cause serious injury to the operator. Therefore, safety devices are crucial for ensuring the safety of operators.

[0003] Existing sliding door covers generate a lot of mud due to long-term cutting, and the mud and sand are difficult to remove. The mud and sand accumulate between the guide rail and the roller, causing serious mud accumulation between the roller and the guide rail. Over time, this can cause the sliding door to jam. At the same time, the roller is exposed to mud and sand, making operation difficult and affecting production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel sliding door for multi-wire saw machine protection to solve the aforementioned problems.

[0005] This utility model provides the following technical solution:

[0006] A novel sliding door for a multi-wire saw machine includes an upper sliding door and a lower sliding door. The bottom of the upper sliding door and the top of the lower sliding door are separated by a certain gap. The upper sliding door is provided with a non-contact transverse guide rail that is in contact with the lower sliding door. A roller support frame is fixed on the lower sliding door. The roller support frame is used to fix a roller assembly that works in conjunction with the transverse guide rail.

[0007] Furthermore, the transverse guide rail is located between the top frame and the bottom crossbar of the upper cover sliding door.

[0008] Furthermore, the roller support frame includes two vertical bars that are laterally spaced at a certain distance.

[0009] Furthermore, the roller assembly includes a small wheel assembly and a large wheel assembly, which are respectively mounted on two vertical bars of the roller support frame.

[0010] Furthermore, the roller support frame has a limiting block on the vertical bar near the side.

[0011] Furthermore, the lower cover is also provided with a lower cover support rod, and the side of the lower cover is also provided with support rollers.

[0012] Furthermore, the small wheel assembly includes four small rollers, two of which are distributed above and below the transverse guide rail; the large wheel assembly includes two large rollers, one of which is distributed above and below the transverse guide rail.

[0013] Furthermore, the bottom horizontal frame of the upper protective sliding door is also equipped with a brush.

[0014] Furthermore, the upper protective sliding door also includes a door handle and a door latch.

[0015] This utility model has the following beneficial technical effects:

[0016] This invention utilizes a fixed mechanism between large and small roller assemblies and a lower protective cover supporting the roller frame. This, combined with the upper horizontal guide rail, enables smooth sliding without jamming. Furthermore, the roller assemblies and guide rails are positioned far from the lower protective cover, making it difficult for mud and sand to contact the roller assemblies during stone cutting. Simultaneously, the mud and sand will fall off the guide rails due to gravity, effectively solving the problem of sliding doors jamming due to mud and sand accumulation between the guide rails and rollers.

[0017] This invention further divides the roller assembly into two groups of different sizes. The smaller rollers mainly serve to clamp and support the guide rail, preventing the horizontal guide rail from deviating vertically. The larger rollers can counteract the deviation of the sliding door caused by changes in the center of gravity. When the upper cover sliding door is fully opened, the larger roller assembly separates from the horizontal guide rail, and the side of the upper cover sliding door is supported by the rollers to maintain its horizontal movement. The entire sliding process ensures that the upper cover sliding door does not deform too much during movement, while also preventing the upper cover sliding door from tilting.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figure 1-2 This embodiment discloses a novel sliding door for a multi-wire saw machine guard. The figure shows the open and closed states of the novel sliding door for a multi-wire saw machine guard.

[0029] Specifically, see Figure 3-6 A novel sliding door for a multi-wire saw machine includes an upper sliding door 5 and a lower sliding door 9. The upper sliding door 5 includes a top frame and a bottom crossbar, which are connected by vertical bars and side diagonal bars. The upper sliding door 5 uses limiting aluminum profiles 10. The lower sliding door 9 is fixed to the frame of the multi-wire saw machine. The upper sliding door 5 and the lower sliding door 9 are set with a certain gap in the vertical direction. The upper sliding door 5 is provided with a non-contact horizontal guide rail 7 that is located between the top frame and the bottom crossbar of the upper sliding door 5. A roller support frame 13 is fixed on the lower sliding door 9. The roller support frame 13 includes two vertical bars that are horizontally spaced at a certain distance. The top of the two vertical bars is fixedly connected by a short horizontal bar. The roller support frame 13 is used to fix the roller assembly that cooperates with the horizontal guide rail 7. The roller assembly includes a small roller assembly 4 and a large roller assembly 6. The small roller assembly 4 and the large roller assembly 6 are respectively mounted on two vertical rods of the roller support frame 13. The small roller assembly 4 includes four small rollers, and the large roller assembly 6 includes two large rollers. Both the large and small rollers are distributed in two rows above and below the transverse guide rail 7 to clamp the transverse guide rail 7. There are two small rollers on each side of the transverse guide rail 7, and one large roller on each side of the transverse guide rail 7. The large and small rollers adopt a V-shaped structure.

[0030] The lower cover 9 is a triangular frame, and its side is also equipped with support rollers 2. When the upper cover sliding door 5 is fully opened, it moves above the support rollers 2, ensuring that the sliding door cover does not deform too much during movement and preventing the sliding door from tilting. The lower cover 9 is also equipped with a lower cover support rod 1 to strengthen its structural strength.

[0031] The roller support frame 13 has a limiting block 3 on the vertical rod near the side to restrict the lateral movement of the upper cover sliding door 5, so that the upper cover sliding door 5 stops moving. A brush 12 is provided between the upper cover sliding door 5 and the lower cover 9.

[0032] The upper protective sliding door 5 also includes a door handle 11 for pushing and pulling the upper protective sliding door 5, and the upper protective sliding door 5 is also provided with a door latch 8 for locking the upper protective sliding door 5.

[0033] In this embodiment, when the upper cover sliding door 5 is pushed or pulled, the roller assembly moves on the horizontal guide rail 7. Since the roller assembly remains stationary, the horizontal guide rail 7 slides back and forth on the rollers. The door handle 11 can reduce the force of pushing and pulling. The roller assembly is divided into two groups of large and small rollers. The small rollers mainly serve to clamp the guide rail, so that the horizontal guide rail 7 does not deviate vertically. The large rollers can counteract the deviation of the sliding door caused by the change of the center of gravity. When the upper cover sliding door 5 is fully opened, the large roller assembly separates from the horizontal guide rail 7, and the side of the upper cover sliding door 5 is supported by the support rollers 2 to maintain its ability to move horizontally.

[0034] When the upper cover sliding door 5 is opened or closed, the guide rail and the small wheel assembly 4 always maintain two-point contact, while the large wheel assembly 6 can adjust for excessive deformation of the guide rail. When closed, the sliding door remains horizontal under the action of the large roller and the door latch clamp 8; when the sliding door is opened, the guide rail will disengage from the large roller, but before disengaging, it will contact the support roller below to ensure the horizontal movement of the guide rail. In addition, the limit block 3 acts as a travel limit for the sliding door. When the sliding door is fully opened, the limit block 3 restricts the lateral movement of the upper cover sliding door 5 and stops it at the vertical side of the small wheel assembly 4.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
