Description

Technical Field

[0001] The utility model relates to a fire protection pipeline fixed-length cutting auxiliary device, belonging to the technical field of pipeline cutting. Background Art

[0002] Saw blade hand-cranked cutting machine is a commonly used cutting equipment in pipe cutting. Its principle is to manually operate the handle or foot pedal to drive the transmission system. The transmission system drives the saw blade to rotate, forming a cutting force. The saw blade is aligned with the workpiece and pushed in the predetermined direction. The saw blade can then cut the workpiece.

[0003] To improve construction efficiency and reduce costs, standardized design and construction methods are often adopted. Using pipes of uniform lengths can reduce adjustments during installation, improving installation speed and quality.

[0037] Example

[0038] This embodiment aims to address the cumbersome and inefficient process of cutting pipes using a hand-cranked saw blade cutter. This embodiment provides a fire protection pipe cutting aid, wherein a cutting device 100 is secured by a base 1. A fixed-length barrier assembly 2 can be positioned on a measuring rail 11 according to the desired pipe length. The pipe to be cut is placed on the cutting device 100, pushed against the fixed-length barrier assembly 2, and the saw blade of the cutting device 100 is shaken to cut the pipe. Each cut pushes the pipe against the fixed-length barrier assembly 2, resulting in multiple pipe sections of uniform length. The fixed-length barrier assembly 2 is adjustable, making it suitable for cutting pipes of various lengths.

[0039] Reference Figure 1-3 As shown, a fire protection pipe cutting auxiliary device includes a base 1, a fixed-length baffle assembly 2, and a stopper 3. The base 1 is detachably connected to the cutting device 100. For example, the base 1 can be a platform work surface for placing the cutting device 100, or it can be a support frame. The base 1 includes a ruler track 11 disposed on the base 1 body. The ruler track 11 is arranged along the pipe conveying direction of the cutting device 100. For example, the ruler track 11 is perpendicular to the saw blade of the cutting device 100. The fixed-length baffle assembly 2 is slidably connected to the ruler track 11. The fixed-length baffle assembly 2 corresponds to the position where the pipe is conveyed from the cutting device 100. The stopper 3 is movably connected to the fixed-length baffle assembly 2. When the stopper 3 is driven, it can abut against one side of the ruler track 11, thereby securing the fixed-length baffle assembly 2 to the ruler track 11. The fixed-length baffle assembly 2 can be fixed on the ruler track 11 according to the required pipe length. Exemplarily, the limiting member 3 may be a screw.

[0040] Reference Figure 1 and 2As shown, the fixed-length barrier assembly includes: a sliding member 21, a baffle member 22, an elastic reset member 23 and a traction rope body 24. The sliding member 21 is slidably connected to the measuring track member 11. The baffle member 22 is slidably connected to the sliding member 21, and the sliding direction of the baffle member 22 is perpendicular to the pipe conveying direction of the cutting device 100. For example, the baffle member 22 is parallel to the saw blade of the cutting device 100. The elastic reset member 23 is respectively connected to the sliding member 21 and the baffle member 22. After the contact control of the baffle member 22, the elastic reset force of the elastic reset member 23 can pull the baffle member 22 back to its original position, that is, corresponding to the pipe conveying direction of the cutting device 100. The baffle member 22 can be a plate that can block one end of the pipe.

[0041] Reference Figure 1 and 2 As shown, a loop 241 is provided in the middle of the traction rope 24. The two ends of the loop 241 are connected to the sliding member 21 and the base 1, respectively. The two ends of the traction rope 24 are connected to the baffle member 22 and the cutting swing end of the cutting device 100, respectively. When the cutting swing end of the cutting device 100 is shaken, one end of the traction rope 24 is pulled out and the other end of the traction rope 24 is retracted, driving the baffle member 22 to move away from the pipe conveying direction of the cutting device 100. It should be noted that the cutting device 100 is arranged on the base 1, so there is a height difference between the working surface of the cutting device 100 and the ground. When the pipe is cut, the baffle member 22 moves away from the pipe conveying direction of the cutting device 100, and the baffle member 22 releases the limit on one end of the pipe. The cut pipe automatically falls out of the height difference state, eliminating the need for the user to remove the pipe, thereby improving cutting efficiency. In some embodiments, a slope can be provided at the pipe drop location to facilitate the pipe rolling to the next welding step. Among them, a rope loop 241 is provided in the middle of the traction rope body 24, which can be, for example, an existing brake line. The movable ends of the brake line have T-shaped locking ends, which are convenient for connecting to the baffle member 22 and the cutting equipment 100.

[0042] Reference Figure 1 and 2 As shown, the sliding member 21 includes a transfer connection portion 25 arranged on the sliding member body 211, and the transfer connection portion 25 extends to one side of the sliding direction of the baffle member 22. The transfer connection portion 25 is provided with a first slot 251 for the traction rope body 24 to pass through, and the position of the first slot 251 corresponds to the moving direction of the baffle member 22; one end of the rope loop 241 is blocked to the side of the first slot 251 away from the baffle member 22, so as to achieve effective pulling of the baffle member 22.

[0043] Reference Figure 1 and 2As shown, the base 1 includes a limiting support member 12 arranged on the main body of the base 1, and the limiting support member 12 is provided with a second slot 121 for the traction rope 24 to pass through. The position of the second slot 121 is adapted to the position of the cutting swing end of the cutting device 100, and the other end of the rope loop 241 is blocked to the side of the second slot 121 away from the cutting swing end of the cutting device 100, so as to achieve effective pulling of the baffle member 22.

[0044] Reference Figure 2 As shown, the base 1 also includes a clamping assembly 4, which is provided on the base 1 and is used to detachably connect the base 1 to the cutting device 100. The clamping assembly 4 includes a screw 41, one end of which is provided with a handheld rotating nut 42, and the other end is provided with an abutment plate 43 for abutting the workbench of the cutting device 100. The middle portion of the screw is threadedly connected to the base 1 body; the abutment plate 43 and the limiting support member 12 are capable of clamping the cutting device 100.

The snap protrusion 242 can be snapped into the snap groove 261. The snap connector 26 can move synchronously with the cutting swing end of the cutting device 100, driving one end of the traction rope body 24 to move.

[0047] As shown in the figure, the sliding member 21 includes a first sliding groove 212 arranged on the sliding member body 211 and adapted to the ruler rail member 11. The ruler rail member 11 is inserted into the first sliding groove 212 and can slide along the first sliding groove 212; a limit member 3 is provided on one side of the sliding member 21, and one end of the limit member 3 can pass through one side of the first sliding groove 212 and abut against the ruler rail member 11.
