Description

Technical Field

[0001] This utility model relates to the field of water and electricity pipeline cutting technology, specifically a pipeline cutting device for water and electricity installation projects. Background Technology

[0002] During the installation of water and electricity, pipes are cut to adjust their layout and length. The common method of pipe cutting is for the construction workers to first mark the cutting position of the pipe, then fix the pipe on the ground with their feet, and finally cut the pipe with a hand-held cutting machine.

[0003] For larger diameter drain pipes, the cutting blade cannot cut through the pipe. It is necessary to rotate the bottom of the pipe to expose the uncut area before cutting. The uncut areas on both sides of the pipe are also cut by moving the cutting machine. Adjusting the pipe position can easily cause the cut to shift, and moving the cutting machine position can easily cause the saw blade to deviate from the vertical cutting plane, resulting in an uneven pipe cut surface that does not meet the pipe connection process standards. In addition, since the pipe is circular, using a foot-operated method to fix the pipe container makes the pipe unstable. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe cutting device for hydropower installation projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pipe cutting device for hydropower installation projects, comprising:

[0007] L-shaped base plate;

[0008] There are two pedals, both of which are rotatably connected to the top surface of the L-shaped base plate. Stepping on the pedals can limit and fix the pipe.

[0009] A cutting mechanism is arranged in the middle of the top surface of an L-shaped substrate. The cutting mechanism includes two L-shaped rods that are rotatably connected to the L-shaped substrate. A protective cover is fixed between the two L-shaped rods. A slice is rotatably connected inside the protective cover. A motor that can drive the slice to rotate is fixed outside the protective cover.

[0010] A limiting post is fixed to the top surface of the L-shaped base plate, and a bolt capable of fixing the position of the L-shaped rod is screwed onto the top of the limiting post.

[0011] Two limiting components are slidably arranged at both ends of the top surface of the L-shaped substrate, which can limit the pipe to the inside of the L-shaped substrate.

[0012] Furthermore, a screw hole is provided on the outer side of one of the L-shaped rods, and the bolt is detachably screwed into the screw hole.

[0013] Furthermore, the L-shaped substrate has a through hole in the middle and through holes at both ends.

[0014] Furthermore, the top surface of the L-shaped substrate is provided with a rotating groove, and a support shaft that is rotatably connected to the two L-shaped rods is fixed inside the rotating groove.

[0015] Furthermore, the limiting component includes:

[0016] The locking block slides and engages with the L-shaped base plate.

[0017] An inverted bracket is fixed to the top surface of the locking block;

[0018] Bolt 2 is screwed into the middle of the clamping block, and a rubber pad is fixed to the bottom surface of Bolt 2.

[0019] Furthermore, the protective cover is rotatably connected to a connecting shaft in the middle, the connecting shaft is inserted and fixed to the slice, and a gear is fixed to one end of the connecting shaft.

[0020] Furthermore, the output end of the motor is fixed with a second gear, which meshes with the first gear for transmission. The output end of the motor is rotatably connected to an L-shaped rod at a corresponding position, and a handle is fixed between the two L-shaped rods.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By placing the pipe at the right-angle corner of the inner side of the L-shaped base plate and stepping on any of the pedals, the right-angle corner of the L-shaped base plate and the pressed pedals work together to limit and fix the pipe. This effectively prevents the pipe from moving during the cutting process compared to directly stepping on the pipe. By holding the handle on the cutting mechanism, the cutting mechanism is moved towards the pipe. At the same time, the slice on the cutting mechanism rotates, making it easy to directly cut through and sever smaller pipes (the pipe diameter is smaller than the cutting radius of the slice). An L-shaped through hole is pre-set in the middle of the L-shaped base plate at the position corresponding to the slice. The through hole can accommodate the slice that penetrates the pipe and prevent the slice from contacting the ground during the cutting process, thus protecting the slice.

[0023] 2. By placing a larger pipe (with a pipe diameter greater than the cutting radius of the slice) between the L-shaped base plate and the pedal, the top of the pipe is partially cut by rotating the cutting mechanism towards the pipe. Then, the bolt is screwed into the screw hole of the L-shaped rod to fix the cutting mechanism in the cutting position. By moving the clamping block outwards from the pipe, the inverted bracket on the top of the clamping block and the L-shaped base plate limit and clamp the pipe. The slice on the cutting mechanism rotates again. The user rotates the pipe at one end, so that the pipe rotates stably between the inverted bracket and the L-shaped base plate. At the same time, the slice can remain stationary in the cutting position to cut the circumference of the pipe, effectively preventing the pipe from moving away from the cutting position due to rotation, and also effectively preventing the slice from shifting the cutting surface due to moving the cutting machine, which is conducive to cutting a flat pipe cross-section.

Detailed Implementation

[0029] 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.

[0030] Example 1, please refer to Figure 1 - Figure 4In this embodiment of the utility model, a pipe cutting device for hydropower installation engineering includes an L-shaped base plate 100. Two pedals 200 are rotatably connected to the top surface of the L-shaped base plate 100. When a user steps on the pedals 200, the pipe can be fixed in place. A cutting mechanism 300 is provided at the middle position of the top surface of the L-shaped base plate 100. The cutting mechanism 300 includes two L-shaped rods 310 that are rotatably connected to the L-shaped base plate 100. A protective cover 320 is fixed between the two L-shaped rods 310. A cutting blade 321 is rotatably connected inside the protective cover 320. A motor 330 that can drive the cutting blade 321 to rotate is fixed to the outside of the protective cover 320. A limiting post 400 is fixed to the top surface of the L-shaped base plate 100. A bolt 410 that can fix the position of the L-shaped rods 310 is screwed onto the top of the limiting post 400. Limiting components 500 are slidably provided at both ends of the top surface of the L-shaped base plate 100.

[0031] Specifically, by placing the pipe at the right-angle corner of the L-shaped base plate 100, the user can firmly fix the pipe on the L-shaped base plate 100 by stepping on the pedal 200. At the same time, the user can rotate the blade 321 towards the pipe by holding the handle 323 on the cutting mechanism 300, so that the blade 321 can cut the pipe. For larger pipes, after the blade 321 cuts the top part of the pipe, the cutting mechanism 300 is fixed in the cutting position by bolt 410. Then, the pipe is further limited at the right-angle corner of the L-shaped base plate 100 by the limiting component 500. Then, the motor 330 is turned on again to drive the blade 321 to rotate. The user can manually rotate the pipe so that the blade 321 cuts the pipe along the circumference of the pipe. The limiting component 500 prevents the rotating pipe from moving away from the cutting position. The bolt 410 fixes the blade 321 on the cutting mechanism 300 in the cutting position to prevent the blade 321 from deviating from the initial cutting position due to moving the blade 321, which helps to improve the flatness of the cutting of thicker pipe sections.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, an L-shaped rod 310 has a screw hole 311 on its outer side. A bolt 410 is detachably screwed into the screw hole 311. When it is necessary to fix the entire cutting mechanism 300 at the cutting station, the bolt 410 can be screwed into the screw hole 311 of the L-shaped rod 310, so that the L-shaped rod 310 and the entire cutting mechanism 300 remain stationary. Then, by rotating the pipe, the slice 321 can cut the pipe around its perimeter.

[0033] like Figure 3As shown, in this embodiment, a through hole 110 is provided in the middle of the L-shaped substrate 100. When the slice 321 cuts a pipe with a small diameter, the slice 321 will move to the position of the through hole 110 after passing through the pipe to prevent the slice 321 from damaging the L-shaped substrate 100. Through holes 220 are provided at both ends of the L-shaped substrate 100. The through holes 220 facilitate the movement of the pedal 200 towards the L-shaped substrate 100 to press and fix the pipe at the corner of the L-shaped substrate 100.

[0034] In this embodiment, a rubber sleeve is fixed to the outer side of the pedal 200, so that the pedal 200 can be firmly pressed against the outside of the pipe, thereby improving the stability of the pipe fixation. Two rotating seats are fixed to the bottom end of the pedal 200, and a fixed seat that is rotatably connected to the rotating seats is fixed on the L-shaped base plate 100, so that the pedal 200 can be rotated on the L-shaped base plate 100 to adjust its position.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, a rotating groove is provided on the top surface of the L-shaped substrate 100. A support shaft 130 that is rotatably connected to two L-shaped rods 310 is fixed inside the rotating groove, so that the L-shaped rods 310 can rotate and adjust the position of the entire cutting mechanism 300 on the L-shaped substrate 100. When replacing the slice 321, the L-shaped rods 310 can also be rotated away from the L-shaped substrate 100 so that the slice 321 is exposed upwards, which is convenient for replacing the slice 321.

[0036] like Figure 4 As shown, in this embodiment, a connecting shaft is rotatably connected to the middle of the protective cover 320. The connecting shaft is inserted and fixed to the slice 321. A gear 322 is fixed to one end of the connecting shaft that passes through the L-shaped rod 310. A gear 2 is fixed to the output end of the motor 330. The gear 2 meshes with the gear 322 for transmission. The output end of the motor 330 is rotatably connected to the L-shaped rod 310 at the corresponding position. A handle 323 is fixed between the two L-shaped rods 310.

[0037] In this embodiment, when the slice 321 needs to be rotated, the motor 330 drives the gear 2 at its output end to rotate. The gear 2 drives the gear 1 322 to rotate, causing the connecting shaft to rotate, which in turn causes the connecting shaft to rotate and cut the slice 321. An L-shaped support plate is fixed between the lower part of the motor 330 and the protective cover 320, which facilitates the secure mounting of the motor 330 on the outside of an L-shaped rod 310.

[0038] like Figure 2 As shown, in this embodiment, a limiting block 150 is fixed outside the through hole 110 of the L-shaped substrate 100. The limiting block 150 can support the protective cover 320 and prevent the cutting mechanism 300 from moving down too much.

[0039] Example 2, based on Example 1, aims to prevent the thicker pipe from leaving the cutting position during rotation.

[0040] like Figure 3 As shown, in this embodiment, the limiting component 500 includes a locking block 510 that is slidably engaged with the L-shaped substrate 100. A U-shaped frame 520 is fixed on the top surface of the locking block 510. A bolt 530 is screwed into the middle of the top surface of the locking block 510. A rubber pad is sleeved and fixed on the bottom surface of the bolt 530.

[0041] In this embodiment, before rotating the thicker pipe to cut around the pipe, the locking block 510 is moved along the slot 140 on the top surface of the L-shaped base plate 100 toward the pipe, so that the C-shaped bracket 520 on the locking block 510 can abut against the outside of the pipe. Then, the second bolt 530 is rotated so that the bottom of the second bolt 530 can abut against the inside of the slot 140 of the L-shaped base plate 100, so that the limiting component 500 arranged on the outside of the pipe will not move. By fixing a rubber pad at the bottom end of the second bolt 530, it is beneficial to improve the abutment and fixing strength between the second bolt 530 and the bottom surface of the slot 140 when it is screwed down.

[0042] In this embodiment, the two U-shaped frames 520 can also be used to move or transport the cutting device.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
