Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a pipeline cutting device capable of preventing sparks from flying. Background Art

[0002] Pipe processing is a kind of work that makes pipes according to drawings. Pipe processing mainly processes pipes required by industries such as industry, chemical industry, civil use, and construction. Usually, pipe processing is carried out at the construction site. The pipes are processed into appropriate lengths according to the actual size of the installation location to facilitate subsequent installation work.

[0003] When processing pipes, cutting equipment is required. Since pipes are mostly made of metal, a large number of metal sparks will be generated during the cutting process, which can easily cause fires. Therefore, fire prevention measures are usually required at the construction site, such as placing fire extinguishers at the processing location, laying fireproof mats in the processing area, and placing fireproof cloth in the direction of the sparks to catch the sparks.

[0004] In the prior art, although fireproof cloth is placed in the direction of sparks, the sparks will cover a wide range after being splashed. If fireproof cloth is placed outside the cutting equipment, some sparks will still fall outside the fireproof cloth. The high-temperature sparks will contaminate other objects and easily catch fire. Utility Model Content

[0005] The utility model aims to provide a pipe cutting device with the function of preventing sparks from flying, so as to solve the problem in the prior art that, when cutting pipes, a fireproof cloth is arranged on the periphery of the cutting device and all sparks generated by cutting cannot be effectively intercepted.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A pipe cutting device with the function of preventing sparks from flying comprises a base, a support frame is vertically installed on the rear side of the base, the top end of the support frame is connected to a motor above the middle part of the base through a rotating member, a cutting blade is installed on the output shaft of the motor, a baffle is detachably installed on the upper side of the base at the rear side of the cutting blade corresponding to the position of the cutting blade, and a fireproof cloth is installed on the side of the baffle facing the cutting blade.

[0008] A further technical solution is that the baffle is detachably mounted on the upper side of the base through a mounting strip, an insertion slot with an upward opening is provided on the upper side of the mounting strip, and the lower end of the baffle is clamped in the insertion slot.

[0009] A further technical solution is that the fireproof cloth is installed on the baffle through a clamping strip, a clamping slot is provided on the clamping strip, the upper end of the baffle is clamped in the clamping slot, and the upper end of the fireproof cloth is tightly fitted in the clamping slot and the upper end of the baffle.

[0010] A further technical solution is that a processing plate is installed on the upper side of the base below the cutting blade, and a first fixed block and a second fixed block are arranged on the processing plate at intervals on the left and right sides. When the cutting blade moves downward through the rotating member, it is placed in the gap between the first fixed block and the second fixed block; the first fixed block and the second fixed block are respectively provided with a first placement groove and a second placement groove, and the first placement groove and the second placement groove are aligned; the cross-sections of the first placement groove and the second placement groove are both semicircular arcs.

[0011] A further technical solution is that the front and rear sides of the first fixed block are respectively provided with a first wire hole and a second wire hole connected to the first placement slot, and the front and rear sides of the second fixed block are respectively provided with a third wire hole and a fourth wire hole connected to the second placement slot; a fixing rope is provided on the front side of the base, one end of the fixing rope passes through the first wire hole and the second wire hole in sequence, and is connected to the rear side of the first fixed block, and the other end of the fixing rope passes through the third wire hole and the fourth wire hole in sequence, and is connected to the rear side of the second fixed block.

[0012] A further technical solution is that the rotating part includes a rotating seat, a first connecting rod, a second connecting rod and a third connecting rod. The rotating seat is connected to the top of the support frame, the two ends of the first connecting rod are arranged front and back, the rear end of the first connecting rod is vertically connected to the rotating shaft on the rotating seat, the two ends of the second connecting rod are arranged left and right, the left end of the second connecting rod is connected to the front end of the first connecting rod, the two ends of the third connecting rod are arranged front and back, the rear end of the third connecting rod is connected to the right end of the second connecting rod, and the front end is connected to the motor.

[0013] A further technical solution is that a return spring is vertically arranged on the upper side of the rotating seat, and the upper end of the return spring is connected to the lower side of the connection between the first connecting rod and the second connecting rod.

[0014] A further technical solution is that a protective cover for covering the upper part of the cutting blade is installed on the motor.

[0015] Compared with the prior art, the utility model has at least one of the following beneficial effects: 1. By setting a base, the cutting position can be raised to a suitable height. Compared with the direct cutting by placing the transmission on the ground, the degree of bending of the operator can be reduced, and the fatigue of operation can be reduced; 2. When the cutting blade cuts the pipe, sparks will splash out from the back side of the cutting blade. Through the cooperation of the baffle and the fireproof cloth, the splashing sparks can be directly intercepted and fall along the baffle to prevent the sparks from splashing around; 3. The baffle plays a supporting role for the fireproof cloth. The fireproof cloth can be spread out and installed vertically to the position aimed at the spark splashing, so as to intercept the sparks. Moreover, since the texture of the fireproof cloth is relatively soft compared to the baffle, when the spark hits the fireproof cloth, most of the kinetic energy will be buffered, so that it will not be ejected to other positions again.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Figures 1 to 3 Shown is an embodiment of the utility model.

[0022] Embodiment 1:

[0023] like Figure 1As shown, a pipe cutting device with spark splash prevention function includes a base 1, a support frame 2 is vertically installed on the rear side of the base 1, a motor 3 is connected to the top of the support frame 2 above the middle of the base 1 through a rotating member, a cutting blade 4 is installed on the output shaft of the motor 3, and a baffle 5 is detachably installed on the upper side of the base 1 at the rear side of the cutting blade 4 corresponding to the position of the cutting blade 4, and a fireproof cloth 6 is installed on the side of the baffle 5 facing the cutting blade 4. By setting the base 1, the cutting position can be raised to a suitable height, which is lower than the cutting height of a conventional cutting machine, and the cutting is almost close to the ground, which can reduce the degree of bending of the operator and reduce the fatigue of the operation. When the cutting blade 4 cuts the pipe, sparks will splash out from the rear side of the cutting blade 4. Through the cooperation of the baffle 5 and the fireproof cloth 6, the splashing sparks can be directly intercepted and fall down along the baffle 5 to prevent the sparks from splashing around. The baffle 5 supports the fireproof cloth 6, and can spread the fireproof cloth 6 and install it vertically to the position where the sparks are splashed, so as to intercept the sparks. And because the texture of the fireproof cloth 6 is relatively softer than the baffle 5, when the sparks hit the fireproof cloth 6, most of the kinetic energy will be buffered, so that it will not be ejected to other positions again.

[0024] like Figure 2 As shown, the baffle 5 is detachably mounted on the upper side of the base 1 through the mounting strip 7. The upper side of the mounting strip 7 is provided with an insertion slot 8 with an opening facing upward, and the lower end of the baffle 5 is clamped in the insertion slot 8. By providing the mounting strip 7, the baffle 5 can be conveniently installed. Since the baffle 5 can play a huge role during use, if it is installed on the device during transportation, it will cause inconvenience in transportation and cause the device to be too large. Therefore, the baffle 5 can be removed from the mounting strip 7 for separate transportation during transportation. The groove wall of the insertion slot 8 can be provided with a rubber strip, so that when the baffle 5 is inserted, the friction and deformation of the rubber strip can be used to stably insert the baffle 5 into the insertion slot 8.

[0025] like Figure 3 As shown, the fireproof cloth 6 is installed on the baffle 5 through a clamping strip 9, and a clamping slot 10 is provided on the clamping strip 9. The upper end of the baffle 5 is clamped in the clamping slot 10, and the upper end of the fireproof cloth 6 is tightly fitted with the upper end of the baffle 5 in the clamping slot 10. By providing the clamping strip 9, the upper end of the fireproof cloth 6 and the upper end of the baffle 5 can be installed together. At the same time, the lower end of the fireproof cloth 6 is in a free hanging state, so that when the spark hits the fireproof cloth 6, the fireproof cloth 6 can buffer the kinetic energy of the spark by its own loose state, so that the spark will not splash everywhere.

[0026] Embodiment 2:

[0027] On the basis of Example 1, Figure 1As shown, a processing plate 11 is installed on the upper side of the base 1 below the cutting blade 4, and a first fixed block 12 and a second fixed block 13 are arranged on the processing plate 11 at intervals on the left and right. When the cutting blade 4 moves downward through the rotating member, it is placed in the gap between the first fixed block 12 and the second fixed block 13; the first fixed block 12 and the second fixed block 13 are respectively provided with a first placement slot 14 and a second placement slot 15, and the first placement slot 14 and the second placement slot 15 are aligned; the cross-sections of the first placement slot 14 and the second placement slot 15 are both semicircular. By setting the first fixed block 12 and the second fixed block 13, the pipe to be cut can be placed in the first placement slot 14 and the second placement slot 15 of the first fixed block 12 and the second fixed block 13, and then the pipe is cut by the cutting blade 4. By setting the cross-sections of the first placement slot 14 and the second placement slot 15 to be semicircular, the outer wall of the pipe can be relatively close, so that the pipe can be fixed well.

[0028] The first fixing block 12 is provided with a first wire hole 16 and a second wire hole 17 connected to the first placement slot 14 on the front and rear sides respectively, and the second fixing block 13 is provided with a third wire hole 18 and a fourth wire hole 19 connected to the second placement slot 15 on the front and rear sides respectively; a fixing rope 20 is provided on the front side of the base 1, one end of the fixing rope 20 passes through the first wire hole 16 and the second wire hole 17 in sequence, and is connected to the rear side of the first fixing block 12, and the other end of the fixing rope 20 passes through the third wire hole 18 and the fourth wire hole 19 in sequence, and is connected to the rear side of the second fixing block 13. By setting the fixing rope 20, when cutting, by passing the pipe under the fixing rope 20 in the first placement groove 14 and the second placement groove 15, and then stepping on the fixing rope 20 with the sole of the foot to place it in the front side of the base 1, the fixing rope 20 can be tightened so that the fixing rope 20 presses the pipe tightly in the first placement groove 14 and the second placement groove 15. There is no need for the operator to hold down the pipe as in the past, or to fix the pipe by means of a complicated threaded locking ring, etc., which is simple and efficient to operate. The part of the fixing rope 20 placed in the first placement groove 14 and the second placement groove 15 can also be covered with a rubber sleeve, so that friction can be used to prevent the pipe from rotating during cutting. The fixing rope 20 can be made of a steel rope or a fire-resistant rope.

[0029] The rotating member includes a rotating seat 21, a first connecting rod 22, a second connecting rod 23 and a third connecting rod 24. The rotating seat 21 is connected to the top of the support frame 2. The two ends of the first connecting rod 22 are arranged front and back, and the rear end of the first connecting rod 22 is vertically connected to the rotating shaft 25 on the rotating seat 21. The two ends of the second connecting rod 23 are arranged left and right, and the left end of the second connecting rod 23 is connected to the front end of the first connecting rod 22. The two ends of the third connecting rod 24 are arranged front and back, and the rear end of the third connecting rod 24 is connected to the right end of the second connecting rod 23, and the front end is connected to the motor 3. In such a setting, due to the existence of the second connecting rod 23, the position of the first connecting rod 22 can be moved toward the side of the motor 3 by an end distance, so that the edge of the baffle 5 can better block the sparks generated by the cutting position of the cutting blade 4 when it is close to the first connecting rod 22. The front end of the third connecting rod 24 can be provided with a mounting collar that runs through both sides, and the output shaft of the motor 3 is placed in the mounting collar. The third connecting rod 24 is fixedly connected to the end of the motor 3 at the edge of the collar by mounting bolts. A handle 27 is provided on the motor 3 to facilitate the operator to control the motor 3 to drive the cutting blade 4 to move up and down to cut the pipe.

[0030] A return spring 26 is vertically arranged on the upper side of the rotating seat 21, and the upper end of the return spring 26 is connected to the lower side of the connection between the first connecting rod 22 and the second connecting rod 23. By arranging the return spring 26, the motor 3 and the cutting blade 4 can be lifted to a height higher than the position where the pipeline is placed in a natural state, so that the operator only needs to press the handle 27 to drive the cutting blade 4 downward to cut the pipeline during cutting. After the cutting is completed, the cutting blade 4 will rise up, which is convenient for the operator to operate the pipeline.

[0031] A protective cover 28 for covering the upper part of the cutting blade 4 is installed on the motor 3. By providing the protective cover 28, the upper side of the cutting blade 4 can be effectively protected to avoid accidental touch by the operator.
