Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a protective structure for the main beam of a bridge-type cutting machine. Background Technology

[0002] Stone cutting machines are mainly used for cutting and processing stone slabs. A conventional bridge-type stone cutting machine consists of a cutting assembly and a worktable. The cutting assembly includes two longitudinal beams, a crossbeam (also called a main beam) between the two longitudinal beams, a movable seat on the crossbeam that can move laterally, a lifting frame on the movable seat that can be raised and lowered, and a cutting device on the lifting frame. In the process of stone cutting with a traditional bridge-type cutting machine, the cutting wastewater from the cooling blades carries a large amount of stone dust and powder. This wastewater is flung out by the high-speed rotating cutting blades during processing. Traditional cutting machines only have a water-blocking cloth installed on the water-splashing side of the blades to block the splashed wastewater, but its blocking effect is not good. During processing, the wastewater easily splashes out without being blocked by the water-blocking cloth. The wastewater generally contains a large amount of stone dust and powder, causing factory pollution. The dust also damages the cutting equipment. Furthermore, the sparks and vibrations generated during cutting cannot be effectively prevented from causing damage.

[0003] To address this, some improvements have been made to the bridge-type cutting machine. For example, Chinese patent document CN202221643148.3 discloses a bridge-type cutting machine with a dust-blocking function. This machine includes a bridge-type cutting machine body, a gantry frame on the machine body, and a horizontally movable cutting head mounted on the gantry frame. A cutter head protective cover is installed on the cutting head, comprising a blade cover and a dust cover. The dust cover has a movable locking component, and the blade cover has a locking hole. The movable locking component engages with a spring-loaded locking mechanism in the locking hole. A wheel is located on the lower bottom of the dust cover. The dust cover is used to block splashed cutting cooling water containing dust. This utility model utilizes the dust cover to block splashed cutting cooling wastewater, thereby blocking and collecting the dust contained in the wastewater, preventing dust splashing, pollution, and damage to the equipment. However, it cannot effectively protect the main beam of the bridge cutting machine, which allows wastewater, sparks, etc. to splash onto the main beam during operation. Dust and other substances adhere to the main beam, causing dirt or sparks to fall and damage it. This leads to unstable operation of the moving seat on the main beam, affecting the cutting accuracy. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a bridge-type cutting machine beam protection structure that is structurally stable and durable, effectively protects the main beam, and ensures stable operation and cutting accuracy.

[0005] To solve this technical problem, the present invention adopts the following solution: a protective structure for a bridge-type cutting machine beam, including a protective cover installed on the main beam of the bridge-type cutting machine. The protective cover is detachably installed on the upper surface of the beam. The top of the protective cover includes a plurality of parallel and connected guide slopes. The top cross section of each guide slope is an acute angle with one side vertical and the other side inclined, and the inclination direction of each guide slope is the same. Sealing strips are provided on both sides of the protective cover, and neodymium iron boron magnetic strips are embedded in the sealing strips.

[0006] A further improvement is that the acute angle of the cross section at the top of each of the aforementioned guide slopes is 15°-45°.

[0007] A further improvement is that the channels formed between the various guide slopes are set at an angle from one side to the other.

[0008] In a further improvement, the bottom of the groove at the top of the protective cover is 1cm-3cm higher than the other end.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By setting a protective cover on the main beam and then movably fitting the movable seat onto the main beam with the protective cover, and setting the top surface of the protective cover as a peak-valley structure with multiple guide slopes connected by an acute-angled top section to disperse impact stress, the overall mechanical impact resistance of the protective cover is enhanced by more than 20%, making the structure stable and durable, effectively protecting the main beam, ensuring the stable movement and operation of the cutting device, and effectively ensuring cutting accuracy. The sealing strip is embedded with neodymium iron boron magnetic strips and forms a 0.2mm gap with the steel main beam for adsorption, extending the life of the seal by more than 5 times compared to traditional rubber seals, resulting in better protective effect of the protective cover, and quick and convenient disassembly during maintenance. By setting the guide slopes as an acute angle of 15°-30° with one side vertical and the other inclined, the top surface of the protective cover can be automatically swept away by the airflow of the cutting machine. Furthermore, the grooves formed between the guide slopes are inclined from one side to the other, allowing the cutting debris to slide off automatically and improving the cleaning effect of the cutting machine's airflow on the top surface of the protective cover. This design can be widely promoted and applied. Attached Figure Description

[0013] refer to Figures 1-2The preferred protective structure for the main beam of the bridge cutting machine of this utility model includes a protective cover 3 disposed on the main beam 2 of the bridge cutting machine body 1. The protective cover 3 is detachably mounted on the upper surface of the main beam 2. The top of the protective cover 3 includes a plurality of parallel and connected guide slopes 31. The top cross section of each guide slope 31 is an acute angle α with one side vertical and the other inclined, and the inclination direction of each guide slope 31 is in the same direction. The acute angle α of the top cross section of each guide slope 31 is 30°. The protective cover 3 has sealing on both sides. The sealing strip 32 is embedded with a neodymium iron boron magnetic strip. The groove 33 formed between each guide slope 31 is inclined from one side to the other side. The bottom of the groove 33 at the top of the protective cover 3 is 1.5cm higher than the other end. When maintenance is required, the cutting device 12 on the moving seat 11 is removed, and then the moving seat 11 on the main beam 2 is removed. Then, the protective cover 3 can be pried off the main beam 2 by simply disassembling the fixed connection between the two ends of the protective cover 3 and the bridge-type cutting machine body 1.
