Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a power pipe cutting device for electric power construction. Background Art

[0002] Power construction refers to the construction of buildings according to the technical requirements of power construction. Power construction includes a series of work such as wiring and installing power devices. During power construction, workers are usually required to use power pipes according to the actual length and design factors of the building. Before using the power pipes, they need to be cut to length according to standards. Nowadays, cutting of power pipes is carried out using cutting devices.

[0003] The existing patent (Announcement No.: CN221269837U) discloses that coolant is added to the inside of the liquid inlet component box, and the hydraulic component is controlled to drive the box to extend out of the slot, so that the box contacts the cutting knife. The coolant in the box can absorb the heat of the cutting knife through the contact between the cutting knife and the box, thereby cooling the cutting knife and preventing the staff from being burned when accidentally touching the cutting knife.

[0004] However, the existing equipment still has certain shortcomings. First, the equipment only relies on the contact between the box and the cutting blade to cool down, which is too inefficient. When the cutting blade is not completely cooled, accidental burns may still occur. Moreover, it cannot be completed and prepared for the next round of cutting operations in a short time, affecting the cutting efficiency. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide an electric power pipe cutting device for electric power construction to solve the technical problem mentioned in the above background technology that the cooling efficiency is low and may still burn the operator.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a power pipe cutting device for power construction, comprising a bottom shell, a mounting slot, and a cutting device, wherein an electric push rod is installed inside the mounting slot, and a cooling assembly is fixed to the output end of the electric push rod;

[0007] The outer wall of the cooling box is located at the top of the cooling box, and the outer wall of the cooling box is fixed with a water inlet pipe, and the outer wall of the cooling box is fixed with a water outlet pipe, and the water outlet pipe is fixed with a water outlet pipe on the lower left side of the cooling box.

[0008] By adopting the above technical solution, the first flap is first opened, the chiller and the motor are started at the same time, and then the lifting device is started so that the blade of the cutting equipment is closely attached to the surface of the cooling box. Then, fresh coolant flows in from the water pipe port. When it flows through the heat contact surface, it encounters multiple sets of baffles, which to a certain extent reduces the cooling water flow rate, increases the heat transfer time, and improves the heat transfer efficiency, thereby improving the cooling efficiency of the cutting blade. At this time, the motor is used to drive the rotating rod, prompting multiple sets of water paddles to stir the cooling water located between the two sets of partitions and the heat contact surface to maintain uniform heat transfer and further improve the heat dissipation efficiency. At the same time, the rotating rod drives the blower blades to rotate inside the blower box, and the accelerated air is blown toward the surface of the cutting blade through the bent pipe to accelerate the cooling of the cutting blade. After the cooling water completes a circulation process, the hot water flows from the water outlet through the hose into the chiller for cooling, and then flows back into the cooling box through the water inlet pipe and the hose, realizing the recycling of the cooling water. Secondly, the cover plate is used to block most of the debris and sparks generated during cutting, and the debris is collected in the chip collection box, reducing the intensity of subsequent site cleaning for the operator.

[0009] Furthermore, a plurality of grooves are evenly spaced on an inner wall of the cooling box on a side close to the cutting device, and a plurality of heat dissipation fins are fixedly connected to an outer wall of the cooling box on a side away from the cutting device.

[0010] By adopting the above technical solution, multiple sets of grooves can increase the contact area with the cooling water, while reducing the thickness and improving the heat dissipation efficiency. Multiple sets of heat dissipation fins can dissipate the cooling water in the cooling box to a certain extent.

[0011] Furthermore, the corners of one end of the plurality of groups of slow flow plates that are close to each other are all provided with oblique openings, and the stirring direction of each group of water blades is opposite to the water inlet pipe opening.

[0012] By adopting the above technical solution, the stirring direction of each set of water blades is opposite to the water inlet pipe, which can ensure the smooth flow of cooling water.

[0013] Furthermore, the end of the blower blade is connected to a conical nozzle, and the water inlet and outlet of the cooling box are connected to the output and input pipes of the chiller through a hose, and a one-way valve is installed at the connection between the hose and the water outlet of the cooling box.

[0014] By adopting the above technical solution, the conical nozzle can concentrate high-speed gas to the cutting blade to accelerate the cooling efficiency. A one-way valve is installed at the connection between the hose and the water outlet of the cooling box to facilitate the injection of new coolant.

[0015] Furthermore, a first flip cover is rotatably connected to the top position of one side of the mounting slot, and a limiting slot is provided at the end of the mounting slot away from the first flip cover. A mounting plate is fixedly connected to the upper surface of one side of the bottom shell, and a lifting device is movably installed on the outer wall of the mounting plate, and the cutting equipment is fixedly installed on the upper surface of the lifting device by fixing bolts.

[0016] By adopting the above technical solution, the first flip cover can protect the cooling assembly, and the limiting groove can limit and fix the first flip cover.

[0017] Furthermore, a cover plate is fixedly installed on one side outer wall of the bottom shell, a cavity is opened inside the cover plate, and the cavity fits the bottom shell, a sliding box is fixedly connected to the bottom outer wall of the cover plate, and a chip collecting bucket is slidably sleeved inside the sliding box.

[0018] By adopting the above technical solution, the cover plate can block the sparks and debris generated during cutting, reduce the contaminated area, and at the same time use the internal cavity to introduce the debris and sparks into the chip collection bucket for centralized cleaning.

[0019] Furthermore, a plurality of mounting brackets are symmetrically fixedly connected to the side of the upper surface of the bottom shell away from the mounting plate, a control device is fixedly installed on the side wall of the bottom shell located on the side of the cover plate, a second flip cover is rotatably connected to the port of the mounting chamber on one side surface of the bottom shell, universal wheels are fixedly installed at the four corners of the lower surface of the bottom shell, and a heat dissipation window is provided on the outer wall of the side of the bottom shell away from the mounting plate.

[0020] By adopting the above technical solution, multiple sets of mounting frames can be used to install multiple sets of pipe fixing brackets in subsequent use, thereby improving practicality. The second flap can protect the chiller inside the installation chamber, and the universal wheels can enable the device to be moved at will, thereby improving the convenience of the device.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The utility model starts the chiller, motor and lifting device first and makes the cutting blade fit the surface of the cooling box, and then fresh coolant flows in from the water pipe mouth. When it flows through the thermal contact surface, multiple sets of baffles reduce the cooling water flow rate to a certain extent, increase the heat transfer time, and improve the heat transfer efficiency, thereby improving the cooling efficiency. At this time, the motor is used to drive the rotating rod to prompt multiple sets of water paddles to stir the cooling water between the two sets of partitions and the thermal contact surface to maintain uniform heat transfer and further improve the heat dissipation efficiency. At the same time, the rotating rod drives the blower blades to rotate inside the blower box, and the accelerated air is blown toward the surface of the cutting blade through the bent pipe, thereby accelerating the cooling of the cutting blade.
