[0004] However, in the prior art, steel bars need to be cut to the length of the steel bars according to the use requirements when they are used, and since the construction working environment is relatively harsh, most of the cutting devices cannot be placed on a flat ground when they are used, resulting in the cutting platform being unable to be horizontal with the ground when it is used, which seriously affects the smooth progress of the steel bar cutting work. A solution is proposed to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a steel bar cutting device for construction, which aims to improve the problem that steel bars need to be cut to the length according to the use requirements during use. However, due to the harsh environment of construction work, most of the cutting devices cannot be placed on a flat ground during use, resulting in the cutting platform being unable to be horizontal with the ground during use, which seriously affects the smooth progress of the steel bar cutting work.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a cutting table, both sides of the lower end of the cutting table are slidably connected with connecting plates, both sides of the lower ends of the two connecting plates are fixedly connected to support rods, the interiors of the four support rods are slidably connected with lifting blocks, the lower ends of the four lifting blocks are fixedly connected to the fixing rods, the lower ends of the four fixing rods are fixedly connected to the bottom plate, one side of the four lifting blocks is rotatably connected to the movable rod, and the other ends of the four movable rods are rotatably connected to the slider, and a No. 1 two-way screw rod is provided on both sides of the lower end of the cutting table, and one end of the two No. 1 two-way screw rods is connected to two of the support rods One side is rotatably connected, and one side of the four sliders is respectively threadedly connected to the two sides of the outer surface of the two No. 1 bidirectional screw rods, and a sliding rod is provided above the two No. 1 bidirectional screw rods, and the outer surfaces of the two sliding rods are respectively slidably connected to one side of the four sliders, and the two ends of the two sliding rods are respectively fixedly connected to one side of the four support rods, and one end of the two No. 1 bidirectional screw rods respectively passes through one side of the other two support rods and is fixedly connected to a No. 1 handle, and the lower end of the cutting table is rotatably connected to a threaded rod, and the outer surfaces of the threaded rods are respectively threadedly connected to the middle parts of the two connecting plates, and one end of the threaded rod is fixedly connected to the No. 2 handle.

[0007] As a further description of the above technical solution: when the ground at the construction site is uneven and the cutting table cannot be placed normally, the No. 2 handle can be turned to drive the threaded rod to rotate, and the rotating threaded rod can drive the two connecting plates to move to both sides, so that the support rods are separated from each other, which can be used to increase the support area of ​​the bottom of the cutting table. Then, the No. 1 handle is turned according to the depression of the ground, and the No. 1 bidirectional screw rod is driven to rotate by the No. 1 handle. When the No. 1 bidirectional screw rod rotates, it can control the slider to gather or disperse on the No. 1 bidirectional screw rod. When the slider disperses, its two movable rods will move and rotate to both sides to push the lifting block to move downward. After the lifting block moves downward, its bottom plate will be pushed downward to extend the length of its support rod to compensate for the height of the depression in the ground. Otherwise, the slider can be gathered together, and the lifting block will move upward to shorten the length of the support rod. Through this method, when using the device, if the ground depression at the construction site is large, the cutting table can be leveled by adjusting the length of the support rod, so that the device can adapt to construction sites with different ground conditions.

[0008] Preferably, the instrument on the upper end of the cutting table is fixedly connected to a mounting table, and the upper end of the mounting table is rotatably connected to a mounting rod.

[0009] As a further description of the above technical solution: the mounting platform can be used to fix the mounting rod, and the mounting rod can be used to install the cutting mechanism.

[0010] Preferably, one end of the mounting rod is fixedly connected to a cutting mechanism, and the other side of the cutting mechanism is fixedly connected to a number three handle.

[0011] As a further description of the above technical solution: the cutting mechanism can cut the steel bars, and the No. 3 handle can be used to adjust the height of the cutting mechanism to cut the steel bars.

[0012] Preferably, both sides of the upper end of the cutting table are fixedly connected with placement blocks, and the upper ends of the two placement blocks are provided with placement grooves.

[0013] As a further description of the above technical solution: the placement slot on the placement block can be used to place steel bars.

[0014] Preferably, one side of the two placement slots is provided with an installation slot, and both sides of the two installation slots are rotatably connected to a clamping rod No. 1.

[0015] As a further description of the above technical solution: the mounting groove can be used to fix the No. 1 clamping rod and the No. 2 clamping rod.

[0016] Preferably, the upper ends of the two mounting grooves are fixedly connected to a No. 2 clamping rod, and the upper ends of the four No. 1 clamping rods are fixedly connected to a No. 1 rubber block.

[0017] As a further description of the above technical solution: the ends of the No. 1 clamping rod can clamp both sides of the steel bar after being gathered together.

[0018] Preferably, the upper ends of the two No. 2 clamping rods are fixedly connected to the No. 2 rubber block, and the lower ends of the four No. 1 clamping rods are rotatably connected to the connecting block.

[0019] As a further description of the above technical solution: Rubber block No. 1 and rubber block No. 2 can be used to increase the friction between the ends of clamping rod No. 1 and clamping rod No. 2, making the steel bars more stable after clamping.

[0020] Preferably, one side of the two placement blocks is rotatably connected to a No. 2 bidirectional screw rod, and the outer surfaces of the two No. 2 bidirectional screw rods are respectively threadedly connected to one side of the four connection blocks.

[0021] As a further description of the above technical solution: after rotation, the No. 2 bidirectional screw rod can be used to adjust the connection blocks to disperse or gather, so as to adjust the No. 1 clamping rod for clamping.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are:

[0023] When the cutting table is flat, the two connecting plates can be moved to the sides by rotating the second handle, so that the two connecting plates can be moved to the sides, and the support rods can be separated from each other, which can be used to increase the support area of ​​the bottom of the cutting table. Then, according to the depression of the ground, the first handle is rotated, and the first handle drives the first bidirectional screw rod to rotate. When the first bidirectional screw rod rotates, it can control the slider to gather or disperse on the first bidirectional screw rod. When the slider disperses, the two movable rods will move to the sides and rotate accordingly to push the lifting block to move downward. After the lifting block moves downward, its bottom plate will be pushed downward, thereby extending the length of the support rod to compensate for the depression of the ground. Otherwise, the slider can be gathered together, and the lifting block will move upward to shorten the length of the support rod. By this method, when using the device, if the ground depression at the construction site is large, the length of the support rod can be adjusted to make the cutting table level, so that the device can adapt to construction sites with different ground conditions.

[0024] 2. In the utility model, when cutting the steel bar, the steel bar can be placed between the No. 2 clamping rod and the No. 1 clamping rod, and then the No. 2 bidirectional screw rod is rotated. The rotating No. 2 bidirectional screw rod can drive the two connecting blocks to separate from each other. After the connecting blocks are dispersed, the No. 1 clamping rod will be driven to rotate. At this time, the upper ends of the No. 1 clamping rod will gather together, so that the No. 1 rubber block on the No. 1 clamping rod is tightly clamped on the outer surface of the steel bar. Through this method, when clamping the steel bar, the No. 1 rubber block and the No. 2 rubber block can be used to clamp the bottom and both sides of the outer surface of the steel bar respectively, so that the steel bar is more stable during cutting. At the same time, the device can also adjust the clamping spacing according to the thickness of the steel bar, so that the device can clamp more types of steel bars.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 As shown, an embodiment of the present invention includes a cutting table 1, both sides of the lower end of the cutting table 1 are slidably connected with connecting plates 14, both sides of the lower ends of the two connecting plates 14 are fixedly connected to support rods 6, the interiors of the four support rods 6 are slidably connected with lifting blocks 15, the lower ends of the four lifting blocks 15 are fixedly connected to fixed rods 16, the lower ends of the four fixed rods 16 are fixedly connected to the bottom plate 7, one side of the four lifting blocks 15 is rotatably connected to a movable rod 18, the other ends of the four movable rods 18 are rotatably connected to a slider 12, and both sides of the lower end of the cutting table 1 are provided with a No. 1 bidirectional screw rod 11, one end of the two No. 1 bidirectional screw rods 11 is connected to two of the support rods 6 One side is rotatably connected, one side of the four sliders 12 is respectively threadedly connected to the two sides of the outer surface of the two No. 1 bidirectional screw rods 11, and a slide rod 17 is provided above the two No. 1 bidirectional screw rods 11. The outer surfaces of the two slide rods 17 are respectively slidably connected to one side of the four sliders 12, and the two ends of the two slide rods 17 are respectively fixedly connected to one side of the four support rods 6. One end of the two No. 1 bidirectional screw rods 11 passes through one side of the other two support rods 6 and is fixedly connected to the No. 1 handle 8. The lower end of the cutting table 1 is rotatably connected to the threaded rod 13, and the outer surfaces of the threaded rod 13 are respectively threadedly connected to the middle part of the two connecting plates 14, and one end of the threaded rod 13 is fixedly connected to the No. 2 handle 9.

[0033] In this embodiment, when the ground at the construction site is uneven and the cutting table 1 cannot be placed normally, the second handle 9 can be rotated to drive the threaded rod 13 to rotate. The rotating threaded rod 13 can drive the two connecting plates 14 to move to both sides, so that the support rods 6 are separated from each other, which can be used to increase the support area of ​​the bottom of the cutting table 1. Then, the number one handle 8 is rotated according to the concave condition of the ground, and the number one bidirectional screw rod 11 is driven to rotate by the number one handle 8. When the number one bidirectional screw rod 11 is rotated, the slider 12 can be controlled to gather or disperse on the number one bidirectional screw rod 11. When dispersed, its two movable rods 18 will move to both sides and rotate accordingly to push the lifting block 15 downward. After the lifting block 15 moves downward, its bottom plate 7 will be pushed downward to extend the length of its support rod 6 to compensate for the height of the depression in the ground. Conversely, the sliders 12 can be gathered together, and its lifting block 15 will move upward to shorten the length of the support rod 6. Through this method, when using the device, if the ground depression at the construction site is large, the cutting table 1 can be horizontal by adjusting the length of the support rod 6, so that the device can adapt to construction sites with different ground conditions.

[0034] Example 2, as Figure 1 、 Figure 2 and Figure 4 As shown, the instrument at the upper end of the cutting table 1 is fixedly connected to the mounting table 5, and the upper end of the mounting table 5 is rotatably connected to the mounting rod 4, one end of the mounting rod 4 is fixedly connected to the cutting mechanism 3, and the other side of the cutting mechanism 3 is fixedly connected to the No. 3 handle 2. Both sides of the upper end of the cutting table 1 are fixedly connected to the placement blocks 10, and the upper ends of the two placement blocks 10 are provided with placement grooves 26, and one side inside the two placement grooves 26 is provided with a mounting groove 20, and both sides inside the two mounting grooves 20 are rotatably connected to the No. 1 clamping rod 21, and the upper ends of the two mounting grooves 20 are fixedly connected to the No. 2 clamping rod 24, and the upper ends of the four No. 1 clamping rods 21 are fixedly connected to the No. 1 rubber block 22, and the upper ends of the two No. 2 clamping rods 24 are fixedly connected to the No. 2 rubber block 23, and the lower ends of the four No. 1 clamping rods 21 are rotatably connected to the connecting block 25, and one side of the two placement blocks 10 is rotatably connected to the No. 2 bidirectional screw rod 19, and the outer surfaces of the two No. 2 bidirectional screw rods 19 are respectively threadedly connected to one side of the four connecting blocks 25.

[0035] In this embodiment, when cutting the steel bars, the steel bars can be placed between the No. 2 clamping rod 24 and the No. 1 clamping rod 21, and then the No. 2 bidirectional screw rod 19 is rotated. The rotating No. 2 bidirectional screw rod 19 can drive the two connecting blocks 25 to separate from each other. After the connecting blocks 25 are dispersed, the No. 1 clamping rod 21 will be driven to rotate. At this time, the upper ends of the No. 1 clamping rod 21 will gather together, so that the No. 1 rubber block 22 on the No. 1 clamping rod 21 is tightly clamped on the outer surface of the steel bar. Through this method, when clamping the steel bar, the No. 1 rubber block 22 and the No. 2 rubber block 23 can be used to clamp the bottom and both sides of the outer surface of the steel bar respectively, so that the steel bar is more stable during cutting. At the same time, the device can also adjust the clamping spacing according to the thickness of the steel bar, so that the device can clamp more types of steel bars.

[0036] Working principle: When the ground at the construction site is uneven and the cutting table 1 cannot be placed normally, the No. 2 handle 9 can be turned to drive the threaded rod 13 to rotate. The rotating threaded rod 13 can drive the two connecting plates 14 to move to both sides, so that the support rods 6 are separated from each other, which can be used to increase the support area of ​​the bottom of the cutting table 1. Then, the No. 1 handle 8 is turned according to the depression of the ground, and the No. 1 bidirectional screw rod 11 is driven to rotate by the No. 1 handle 8. When the No. 1 bidirectional screw rod 11 rotates, it can control the slider 12 to gather or disperse on the No. 1 bidirectional screw rod 11. When the slider 12 disperses, its two movable rods 18 will move and rotate to both sides to push the lifting block 15 to move downward. After the lifting block 15 moves downward, its bottom plate 7 will be pushed downward to extend the length of its support rod 6 to compensate for the depression height of the ground. Otherwise, the sliders 12 can be gathered together, and the lifting block 15 will move upward. It is used to shorten the length of the support rod 6. When cutting the steel bar, it can be used to place the steel bar between the No. 2 clamping rod 24 and the No. 1 clamping rod 21, and then rotate the No. 2 bidirectional screw rod 19. The rotating No. 2 bidirectional screw rod 19 can drive the two connecting blocks 25 to separate from each other. After the connecting blocks 25 are dispersed, the No. 1 clamping rod 21 will be driven to rotate. At this time, the upper ends of the No. 1 clamping rod 21 will gather together, so that the No. 1 rubber block 22 on the No. 1 clamping rod 21 is tightly clamped on the outer surface of the steel bar. Through this method, when clamping the steel bar, the No. 1 rubber block 22 and the No. 2 rubber block 23 can be used to clamp the bottom and both sides of the outer surface of the steel bar respectively, so that the steel bar is more stable during cutting. At the same time, the device can also adjust the clamping spacing according to the thickness of the steel bar, so that the device can clamp more types of steel bars. At this time, the cutting mechanism 3 can be started again to perform the steel bar cutting work.
