Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting, in particular to a steel bar cutting device for earthwork engineering construction. Background Art

[0002] In civil engineering, common earthwork projects include: site leveling, foundation pit and trench excavation, roadbed excavation, civil air defense project excavation, ground filling, roadbed filling and foundation pit backfilling. The construction plan should be arranged reasonably and should not be arranged in the rainy season as much as possible. At the same time, in order to reduce the construction cost of earthwork projects and implement the principle of not occupying or occupying less farmland and arable land and facilitating land reclamation, a reasonable allocation plan for earthwork should be made and overall arrangements should be made.

[0003] An existing patent (authorization announcement number: CN 220112216 U) discloses a steel bar cutting device. During long-term use, the cutting blade of the steel bar cutting device will wear. The cutting blade can be disassembled and replaced separately by cooperating with the threaded barrel and the threaded block, thereby avoiding the situation where the cutting blade causes an uneven cutting surface when worn. At the same time, the cutting blade can be fixed by cooperating with the first fixing block, the second fixing block, the fixing groove and the fixing bolt, which is convenient for disassembly.

[0004] However, the above technical solution still has certain defects. Before and after the cutting of the steel bars, it is necessary to manipulate the fixed structure to clamp or release the steel bars, which makes the steel bar cutting process cumbersome and reduces the efficiency of steel bar cutting in disguise. In addition, the cut steel bars need to be frequently removed from the platform by manual labor, which results in a heavy workload for the manual labor. Therefore, a steel bar cutting device for earthwork engineering construction is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A steel bar cutting device for earthwork engineering construction, such as Figures 1 to 5 As shown, it includes a cutting table 100, a support table 110 is fixed to the bottom end of the cutting table 100, a U frame 130 is fixed to the top of the cutting table 100 near the front and rear edges, and a restraining component 140 is fixed to one side of the U frame 130 at the top of the cutting table 100;

[0026] A groove 101 to be cut is provided on the left side of the top of the cutting table 100, and a plurality of arc grooves 102 are provided at the center of the transverse inner wall of the groove 101 to be cut. A through notch 103 is provided on the right side of the top of the cutting table 100, and a triangular plate 104 is fixed to the left and right inner walls of the notch 103. The front and rear surfaces of the notch 103 and the inner wall of the notch 103 form two groups of material discharge troughs 150.

[0027] An active plate 133 is slidably disposed inside the U frame 130, and a cutting mechanism 132 extending to the front of the active plate 133 is installed at the bottom end of the active plate 133. Two groups of positioning frames 141 are fixed at the front and rear edges of the top of the cutting table 100 on the front side of the U frame 130, and a driven plate 142 is slidably disposed between the two groups of positioning frames 141. A pair of telescopic rods 145 are fixed at the bottom end of the driven plate 142, and a restraining plate 144 is fixed at the bottom end of the telescopic rods 145. Two groups of Z-shaped bars 143 fixed to the driven plate 142 are disposed at the top end of the active plate 133;

[0028] A support plate is fixed on the right side of the support platform 110 below the notch 103, and a collection frame 120 is slidably disposed on the top of the support plate;

[0029] Two sets of electric push rods 131 are installed at the top of the U frame 130. The output ends of the electric push rods 131 pass through the U frame 130 and are fixed to the top of the active plate 133. The cutting mechanism 132 includes a driving motor. A supporting frame fixed to the bottom of the active plate 133 is provided on the outside of the driving motor. The output end of the driving motor is connected to a cutting disk.

[0030] The steel bar is placed on the cutting table 100 and placed in the arc groove 102 opened by the groove 101 to be cut. Then the electric push rod 131 is controlled to work, and its output end is lowered to push the active plate 133 to lower in the U frame 130, and the cutting mechanism 132 at the bottom is lowered to approach the steel bar. At the same time, driven by the Z-shaped bar 143, the driven plate 142 is synchronously lowered, and the telescopic rod 145 and the constraint plate 144 connected to the bottom are also lowered. Because the bottom end of the constraint plate 144 is close to the steel bar, the bottom end of the constraint plate 144 will first contact the steel bar and complete the purpose of clamping and constraining the steel bar, and the telescopic rod 145 is shortened to avoid affecting the electric push rod 131 to continue to lower, until the cutting mechanism 132 contacts the steel bar and completes the cutting effect;

[0031] On the contrary, after the cutting is completed, the output end of the electric push rod 131 rises and recovers, and the contact has the same clamping and restraining effect on the steel bars. The steel bars to be cut are manually pushed closer to the restraining component, so that the cut steel bars can be pushed along with it, so that the cut steel bars fall on the top of the triangular plate 104, roll along the inclined surface through the discharge chute 150 and fall into the collection frame 120, thus achieving the purpose of efficient cutting of the steel bars.

[0032] Please refer to Figure 4 and Figure 5 Both ends of the driven plate 142 are provided with limit blocks extending into the positioning frame 141, and a travel groove is opened at the contact position between the positioning frame 141 and the limit blocks.

[0033] The limit block is made to rise and fall only along the concave straight line of the stroke, so that the driven plate 142 is lowered according to the constrained trajectory, thereby achieving the constraining effect on the steel bars to be cut.

[0034] Please refer to Figure 4 and Figure 5 The bottom end of the telescopic rod 145 is provided with a plurality of arc grooves, and the number of the arc grooves corresponds to the arc grooves 102 one by one.

[0035] The cooperation of multiple groups of arc grooves and the arc groove 102 can fully wrap the outer wall of the steel bar to be cut, thereby increasing the contact surface and achieving the purpose of fixing the steel bar.

[0036] Please refer to Figure 1 and Figure 3 A cutting groove is provided at a position corresponding to the position of the transverse inner wall of the groove to be cut 101 and the cutting mechanism 132, and the depth of the cutting groove is sufficient for the cutting mechanism 132 to be lowered to the lowest point.

[0037] The cutting groove is provided to facilitate the cutting mechanism to fully lower the steel bar to complete the cutting without contacting the cutting table 100 and causing damage.

[0038] When in use, the steel bar is placed on the cutting table 100 and placed in the arc groove 102 opened by the groove 101 to be cut, and then the electric push rod 131 is controlled to work, and its output end is lowered to push the active plate 133 to lower in the U frame 130, and the cutting mechanism 132 at the bottom is lowered to approach the steel bar. At the same time, driven by the Z-shaped bar 143, the driven plate 142 is synchronously lowered, and the telescopic rod 145 and the constraint plate 144 connected to the bottom are also lowered. Because the bottom end of the constraint plate 144 is close to the steel bar, the bottom end of the constraint plate 144 will first contact the steel bar and complete the purpose of clamping and constraining the steel bar, and the telescopic rod 145 is shortened to avoid affecting the electric push rod 131 to continue to lower, until the cutting mechanism 132 contacts the steel bar and completes the cutting effect;

[0039] On the contrary, after the cutting is completed, the output end of the electric push rod 131 rises and recovers, and the contact has the same clamping and restraining effect on the steel bars. The steel bars to be cut are manually pushed closer to the restraining component, so that the cut steel bars can be pushed along with it, so that the cut steel bars fall on the top of the triangular plate 104, roll along the inclined surface through the discharge chute 150 and fall into the collection frame 120, thus achieving the purpose of efficient cutting of the steel bars. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.

[0040] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
