Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a flexible cantilever box mechanism. Background Technology

[0002] With social development, people are increasingly accepting of natural beauty in their interior design, and the desire to experience natural beauty at home has led to a surge in the acceptance of stone decoration. Bridge cutting machines are no longer limited to horizontal and vertical cutting of slabs; they are evolving towards five-axis linkage for deep processing such as cutting, carving, and contouring. During stone cutting, water spray is needed to cool the saw blade. At this time, the saw blade rotates at high speed, and cooling water splashes everywhere. Therefore, mechanical safety barriers are often added to the operator's side. To achieve better protection, the height of the mechanical safety barrier is generally 1.8m. To facilitate worker operation, the key support of the cantilever box is generally about 1.1m above the ground. This can cause interference between the safety door and the cantilever box when opening and closing outward-opening mechanical safety doors. Currently, the cantilever arms of existing cantilever boxes are made of rigid materials. To prevent interference, opening the safety door requires rotating the cantilever box to a large angle and a relatively far position, increasing unnecessary operation. This is very inconvenient for one person to operate, and even more so in workshops with limited space where large-angle rotation of the cantilever box is not possible, potentially affecting the normal operation of the equipment. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a flexible cantilever box mechanism that can rotate at multiple angles, and the cantilever end is connected by a flexible tube, which can be raised and twisted, thus solving the interference problem between the cantilever box and the protective door opening door.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flexible cantilever box mechanism, comprising a hollow vertical wall base, riser I, elbow, horizontal pipe, right-angle box base, riser II, and a height fixing structure connected in sequence. The lower end of riser II is connected to the cantilever box body. The line passes through the vertical wall base, riser I, elbow, horizontal pipe, right-angle box base, and riser II to enter the cantilever box body. The upper end of the vertical wall base is a rotatable interface and is fixedly connected to riser I. The lower end of the right-angle box base is a rotatable interface and is fixedly connected to riser II. Riser II is a flexible pipe. Flanges are provided at both the upper and lower ends of riser II. The upper and lower ends of riser II are fixedly connected to the lower end of the right-angle box base and the top of the cantilever box body respectively through the flanges. The height fixing structure is used to fix the height of the cantilever box body after it is raised.

[0005] The height-fixing structure includes a suspending rod installed on a right-angle base and extending outward along the horizontal tube. The suspending rod is equipped with a suspending device that can lift the cantilever box. With the suspending rod and device installed, when the protective fence needs to be opened for operation, the cantilever box can be lifted and maintained at a certain height, eliminating the need for operators to constantly pull or lift it, thus increasing operational convenience.

[0006] As a preferred embodiment, the lifting device includes a pull rope, the upper end of which is fixed to a lifting rod, and the lower end of which is connected to at least one hook. A fixing ring I is provided at the top of the cantilever box, and the hooks can be hung on the fixing ring I. To facilitate adjustment of the height after lifting, multiple hooks can be installed at different points on the lower end of the pull rope. Hooks at different heights hanging on the fixing ring I can position the cantilever box at different heights.

[0007] Furthermore, a fixing ring II is provided at the base of the pull rope on the lifting rod, and the base of the pull rope is fixed to the fixing ring II. The hook can be hung on the fixing ring II. When it is not necessary to lift the cantilever box, the end of the pull rope can be hung on the fixing ring II to prevent the hook and the end of the pull rope from interfering with the operator.

[0008] As another preferred embodiment, the lifting device includes a rope, the base of which is fixed to the top of the cantilever box. A pulley is provided on the lifting rod, the rope passes through the pulley, and a hook is provided at the end of the rope. At least one hanging ring is provided on the rope from the base upwards, and the hook can be hooked onto the hanging ring. With this design, the cantilever box can be lifted by pulling the rope downwards, making the operation easier for the operator by lifting and pulling with both hands. After the cantilever box is in position, the hook is hooked onto the hanging ring.

[0009] Furthermore, a counterweight is provided above the hook on the pull rope. The weight of the counterweight is less than the force required to pull the cantilever box. The specific weight can be selected and set according to the actual situation. The counterweight can provide some assistance to the operator when pulling the pull rope downwards, making the operation more effortless.

[0010] Furthermore, an auxiliary hanging ring is fixed to the end of the lifting rod, and a hook can be attached to the auxiliary hanging ring. When it is not necessary to lift the cantilever box, the hook at the end of the pull rope can be attached to the auxiliary hanging ring to prevent the hook and the end of the pull rope from interfering with the operator.

[0011] The beneficial effects of this utility model are as follows: the vertical end of the cantilever and the connection section of the cantilever box are set as a flexible structure that can be bent. The cantilever box can be raised to a certain height and the lifting height can be fixed by the sling device, which prevents the cantilever box from interfering with the outward opening door of the protective fence and facilitates the opening and closing operation of the protective fence. The sling and hook of the sling device can be set with several hanging points at different heights to achieve different heights of the cantilever box, which is convenient for different height requirements in stone processing.
