[0018] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the steel pipe protection device for a steel pipe straightening machine of the utility model in conjunction with the accompanying drawings.
[0019] like Figures 1 to 4 As shown, a steel pipe protection device for a steel pipe straightening machine of the utility model comprises a bottom plate 1, a first column 2 is symmetrically arranged at the center of one side of the top surface of the bottom plate 1, and a baffle 3 is symmetrically arranged at the center of the top of the first column 2, and a partition 4 for supporting the steel pipe is distributed between the two baffles 3. Among them, the top surface of the partition 4 is lower than the top surface of the baffle 3, so that the steel pipe can be prevented from slipping off the partition 4 when sliding on the partition 4. At the same time, the top surface of the first column 2 is flush with the top surface of the partition 4, so that when the length of the steel pipe is longer than the spacing between the two first columns 2, the steel pipe and the first column 2 can be prevented from colliding. Of course, it is also feasible that the top surface of the first column 2 is lower than the top surface of the baffle 4, which can meet the use requirements. In order to facilitate the movement of the steel pipe protection device for the steel pipe straightening machine, a universal wheel 12 is distributed on the bottom surface of the bottom plate 1, and the universal wheel 12 is preferably a universal wheel 12 with a brake, which is convenient for fixing the position of the steel pipe protection device for the steel pipe straightening machine.
[0020] The steel pipe on the partition 4 is removed, and a guide plate 5 is provided on the top surface of the bottom plate 1 at an angle relative to the first column 2, and a material ejection assembly 6 is provided on the top surface of the bottom plate 1 to eject the steel pipe on the partition 4 out of the baffle 3. Specifically, the material ejection assembly 6 includes a first electric push rod 61 provided on the bottom plate 1, the first electric push rod 61 is connected to an external power supply for power supply, and a first connecting plate 62 is provided on the telescopic end of the first electric push rod 61, the first connecting plate 62 is located between the two first columns 2 and is slidably arranged between the two first columns 2 to increase the stability of the first connecting plate 62 on the two first columns 2, and at the same time, it can also prevent the first connecting plate 62 from tilting and causing a load on the first electric push rod 61, thereby achieving the purpose of increasing the service life of the first electric push rod 61. There are also inclined blocks 63 distributed at intervals on the top surface of the first connecting plate 62, and the inclined blocks 63 and the partition 4 are staggered. The inclined blocks 63 can pass through the gaps of adjacent partitions 4, and their inclination is inclined toward the guide plate 5. When the steel pipe on the partition 4 needs to be pushed out, the first electric push rod 61 can be started. The first electric push rod 61 drives the inclined block 63 set thereon to rise upward through the first connecting plate 62 and pass through the gap of the adjacent partition 4. The inclined surface of the inclined block 63 contacts the steel pipe on the partition 4, and the steel pipe moves in the opposite direction toward the guide plate 5 along the inclined surface of the inclined block 63 until the lowest position of the inclined surface of the inclined block 63 is flush with the top of the baffle 3. The steel pipe on the inclined block 63 will pass over the baffle 3 and fall onto the guide plate 5, and then fall through the guide plate 5. The first electric push rod 61 drives the inclined block 63 to move downward to the initial position through the first connecting plate 62. In order to reduce the noise when the steel pipe falls on the guide plate 5, a rubber sheet 8 is provided on the guide plate 5.
[0021] like Figure 1 and Figure 3As shown, a second electric push rod 9 is provided on the bottom plate 1, and the second electric push rod 9 is connected to an external power supply, and a blocking part 10 is provided at the telescopic end of the second electric push rod 9 to block the steel pipe sliding off the guide plate 5. The setting of the blocking part 10 can prevent the steel pipe sliding off the guide plate 5 from colliding with the ground, thereby causing damage to the steel pipe. Specifically, the blocking part 10 includes a long strip 101 provided on the telescopic end of the second electric push rod 9, and the long strip 101 and the bottom plate 1 are slidingly arranged, and a blocking arm 102 is obliquely distributed on the long strip 101, and the blocking arm 102 is vertically arranged with the guide plate 5. At the same time, a through hole 51 is also opened on the guide plate 5 at the position corresponding to the blocking arm 102 for its passage. When the first electric push rod 61 is working, the second electric push rod 9 also starts to work, and drives the blocking arm 102 to move toward the right side of the base plate 1 through the long plate 101 and makes the blocking arm 102 pass through its corresponding through hole 51, and then an angle is formed between the blocking arm 102 and the guide plate 5, so that the blocking arm 102 can block the steel pipe sliding down from the guide plate 5, and then the second electric push rod 9 is started again, and the second electric push rod 9 drives the blocking arm 102 to return to the initial position through the long plate 101, and the steel pipe stagnant on the blocking arm 102 will fall to the ground through the guide plate 5 again, reducing the impact force between the steel pipe and the ground.
[0022] In order to reduce the impact of the steel pipe on the barrier arm 102, a buffer part 11 is provided on the barrier arm 102, and the buffer part 11 includes a shock absorber 111 provided on the barrier arm 102, and a buffer block 113 is provided at the telescopic end of the shock absorber 111, and a spring 112 is sleeved on the shock absorber 111 between the barrier arm 102 and the buffer block 113. When the steel pipe falls from the guide plate 5, it will directly contact the buffer block 113, and then the buffer block 113 will impact the barrier arm 102 through the spring 112 and the shock absorber 111, and the spring 112 and the shock absorber 111 will buffer and absorb the impact of the buffer block 113.
[0023] like Figure 2As shown, the two first columns 2 are connected by a second connecting plate 71, and the first electric push rod 61 is located on the second connecting plate 71.

Specifically, the lifting device 7 includes a slider 73 that is symmetrical with the center of the base and is slidably arranged on the base, and the slider 73 is slidably arranged along the length direction of the first connecting plate 62, and a connecting rod 72 is also rotatably arranged on each slider 73, and the free end of each connecting rod 72 is rotatably connected to the second connecting plate 71. At the same time, a motor 74 connected to an external power source is also provided on the bottom plate 1, and a support block 76 is provided on the side of the bottom plate 1 opposite to the motor 74. A positive and negative threaded rod 75 is provided on the output end of the motor 74, and the positive and negative threaded rod 75 passes through two sliders 73, and the two sliders 73 are respectively threadedly connected with two sections of threads on the positive and negative threaded rod 75, and the positive and negative threaded rod 75 is rotatably arranged with the support block 76 relative to one end of the motor 74.

Similarly, when it is necessary to lower the components on the first column 2 and the second connecting plate, the motor 74 can be started to rotate in the opposite direction, and the forward and reverse threaded rod 75 connected to the motor 74 will also rotate in the opposite direction, and the two sliders 73 threadedly connected to the forward and reverse threaded rod 75 will move away from each other, thereby achieving the purpose of lowering the first column 2 and the second connecting plate 71 and the components arranged on the second connecting plate 71. In order to make the first column 2 and the second connecting plate 71 more stable during the lifting process, a second column 13 is arranged on the base corresponding to the position of the first column 2, and the first column 2 and the corresponding second column 13 are arranged for sliding.
[0024] Instructions for use: Move the steel pipe protection device for the steel pipe straightening machine to the outlet side of the straightening machine, then raise the first column 2 and the second connecting plate 71 and the components on the second connecting plate 71 through the lifting device 7, and make the top surface of the partition 4 flush with the lowest end of the straightening machine outlet, and then the steel pipe falls from the straightening machine onto the partition 4, and then start the pushing assembly, the pushing assembly pushes the steel pipe on the partition 4 out of the baffle 3, and then falls on the guide plate 5, when the first electric push rod 61 works, the second electric push rod 9 starts to work, and drives the blocking part 10 to work to block the steel pipe falling from the guide plate 5, and the buffer part 11 on the blocking arm 102 of the blocking part 10 will also buffer the steel pipe, and then the first electric push rod 61 and the second electric push rod 9 can bring the connected components back to the initial position.
