Description

Technical Field

[0001] The utility model relates to the technical field of cement pole processing, in particular to a cement pole steel bar tensioning device. Background Art

[0002] At present, cement poles are mainly composed of steel bars and concrete, so they are also called reinforced concrete cement poles. They are mainly used as wire support pillars in the power, communication, railway, petroleum and other industries.

[0003] Among them, the production process of cement poles requires the following steps: 1. Prepare the raw materials needed to produce cement poles; 2. Use a steel bar straightening and cutting machine to straighten the prepared steel bars according to the specified length and then cut them. If conditions are limited, a wire rod machine can also be used, but the effect is not as good as the steel bar straightening and cutting machine; 3. Prepare a mold for cement poles of relevant length. The mold is generally divided into two halves. The straightened steel bars are coiled into a weft with fine steel wire at the same time, and the steel wire used as the weft is wrapped around the wire. The joints are tied with iron wire, so that the overall skeleton of the cement pole is formed in the mold; 4. After pouring the cement, cover the upper mold and confirm After the gaps on both sides are smaller or closed, the two ends are finally plugged with spouts to prevent the cement from flowing out; 5. Use a hook to adjust the cement pole mold to the centrifuge, and the high-speed rotation of the centrifuge will evenly stick the cement to the inner wall of the mold, so that the cement pole becomes hollow; 6. Then use the gantry crane to lift it into this rectangular semi-underground large container. This rectangular large container is connected to the boiler, which is equivalent to a large steamer. Cover the steamer with a lid and steam the cement pole with high-temperature steam for a period of time to accelerate the solidification of the cement; 7. After setting it aside for a while, use the gantry crane to lift it down, remove the plugs at both ends, and then the cement pole is finished.

[0004] Before pouring mortar into the mold, the operator needs to ensure that the steel cage inside the mold is in a taut state to avoid the complete collapse of the steel cage inside the mold, which would affect the quality of the cement pole. To this end, a new technical solution needs to be designed to ensure that the steel cage is in a taut state inside the mold. Utility Model Content

[0005] The purpose of the utility model is to provide a cement pole steel bar tensioning device, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: a cement pole steel bar tensioning device, comprising a tensioning platform, a steel bar cage is placed on one side of the tensioning platform, a first welding plate is welded to one side of the steel bar cage, a second welding plate is welded to the other side of the steel bar cage, and a steel bar tensioning detection mechanism is installed on one side of the first welding plate and the second welding plate;

[0007] The steel bar tensioning detection mechanism includes a pressure sensor fixedly installed in the middle of the first welding plate, multiple groups of equidistantly distributed spring tubes detachably installed on one side of the first welding plate, a first tensioning plate fixedly installed on the other side of the multiple groups of spring tubes, a screw rotatably installed in the middle of the second welding plate, a hexagonal joint fixedly installed on the other side of the screw, and a second tensioning plate movably installed with the screw.

[0008] As an optional solution of the technical solution of the present application, the pressure sensor corresponds to the first stretching plate, and the first stretching plate is movably connected to one side of the steel cage.

[0009] As an optional solution to the technical solution of the present application, multiple groups of equally spaced limiting holes are provided on the outer side of the second welding plate, and a limiting rod is slidably installed in each group of the limiting holes. One side of the multiple groups of limiting rods is fixedly installed on the outer wall of the second stretching plate, which can limit the second stretching plate.

[0010] As an optional solution of the technical solution of the present application, the pressure sensor is connected to an indicator light via a wire, and the indicator light is located in the middle of the outer side of the first welding plate, which can detect the pressure sensor.

[0011] As an optional solution of the technical solution of the present application, a tensioning mechanism is installed on the inner side of the tensioning platform, and the tensioning mechanism corresponds to the hexagonal joint.

[0012] As an optional solution to the technical solution of the present application, the tensioning mechanism includes limit slides opened on both sides of the tensioning platform, limit frames slidably installed in the two groups of limit slides, a motor fixedly installed between the two groups of limit frames, and a hexagonal socket fixedly installed on the motor shaft of the motor.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

Before pouring mortar in the mold, the technical solution of the present application can first connect the screw on the second welding plate with the hexagonal socket on the tensioning mechanism, drive the screw to rotate continuously, and make the steel cage move continuously to one side. The first welding plate located on the other side of the steel cage will continuously squeeze toward the first stretching plate, and cooperate with the supporting force of multiple sets of spring cylinders installed between the first welding plate and the first stretching plate, so that each group of steel bars can be stretched and straightened. After waiting for the first welding plate and the first stretching plate to fit each other, the pressure sensor on the first welding plate will be squeezed, and the signal will be transmitted to the control processor to control the outer indicator light, which can well prompt the operator to judge whether the steel cage inside the mold is stretched and straightened.

[0015] 2. The technical solution of this application is to install a tensioning mechanism on the inner side of the tensioning table, and the tensioning mechanism corresponds to the hexagonal joint. When the operator pushes the motor in the tensioning table, the hexagonal socket on one side of the motor fits with the hexagonal joint, and drives the motor to drive the hexagonal socket to rotate. As the screw rotates with the hexagonal joint, it will push the motor to move horizontally in the limiting slide groove inside the tensioning table, effectively stretching the steel cage.

The pressure sensor 22 corresponds to the first tensile plate 2, and the first tensile plate 2 is movably connected to one side of the steel cage 1.

[0023] In this technical solution, before pouring mortar in the mold, the screw 23 on the second welding plate 12 can be connected to the hexagonal socket 34 on the tensioning mechanism, driving the screw 23 to rotate continuously, so that the steel cage 1 is continuously moved to one side, and the first welding plate 11 located on the other side of the steel cage 1 will continuously squeeze toward the first stretching plate 2, and cooperate with the supporting force of multiple groups of spring tubes 21 installed between the first welding plate 11 and the first stretching plate 2, so that each group of steel bars can be stretched and straightened, and after waiting for the first welding plate 11 and the first stretching plate 2 to fit each other, the pressure sensor 22 on the first welding plate 11 will be squeezed, and the signal will be transmitted to the control processor to control the outer indicator light 26, which can well prompt the operator to judge whether the steel cage 1 inside the mold is stretched and straightened.

[0024] In some technical solutions, a tensioning mechanism is installed on the inner side of the tensioning platform 3, and the tensioning mechanism corresponds to the hexagonal joint 24. The tensioning mechanism includes limit slides 31 opened on both sides of the tensioning platform 3, limit frames slidably installed in the two groups of limit slides 31, a motor 33 fixedly installed between the two groups of limit frames, and a hexagonal socket 34 fixedly installed on the motor shaft of the motor 33. The hexagonal socket 34 and the hexagonal joint 24 fit together, and the steel cage 1 can be pulled with a rope.

[0025] In this technical solution, when the operator pushes the motor 33 in the tensioning platform 3, the hexagonal socket 34 on one side of the motor 33 fits with the hexagonal joint 24, and drives the motor 33 to rotate the hexagonal socket 34. As the screw 23 rotates following the hexagonal joint 24, it will push the motor 33 to move horizontally in the limiting slide groove 31 inside the tensioning platform 3, effectively stretching the steel cage 1.

[0026] In some technical solutions, the pressure sensor 22 is connected to an indicator light 26 via a wire. The indicator light 26 is located in the middle of the outer side of the first welding plate 11 and can detect the pressure sensor 22.

Finally, fix the first stretching plate 2 and the second stretching plate 25 on both sides of the steel cage 1 on the mold, and wait for mortar to be poured into the mold. At the same time, before pouring mortar into the mold, the screw 23 on the second welding plate 12 can be docked with the hexagonal socket 34 on the tensioning mechanism, and the screw 23 can be driven to rotate continuously, so that the steel cage 1 is continuously moved to one side, and the first welding plate 11 on the other side of the steel cage 1 will continuously squeeze the first stretching plate 2, and the supporting force of multiple sets of spring cylinders 21 installed between the first welding plate 11 and the first stretching plate 2 is coordinated to make each set of steel bars evenly connected.

At the same time, a tensioning mechanism is installed on the inner side of the tensioning platform 3, and the tensioning mechanism corresponds to the hexagonal joint 24. When the operator pushes the motor 33 in the tensioning platform 3, the hexagonal socket 34 on one side of the motor 33 fits with the hexagonal joint 24, and drives the motor 33 to drive the hexagonal socket 34 to rotate.
