Description

Technical Field

[0001] The present invention mainly relates to a steel formwork for green environmental protection concrete poles.

Background Art

[0002] Place the steel formwork of the pole on the running wheels, then put in the steel bars and the mixed concrete, cover the steel formwork and fix it with bolts. The running wheels are driven by a motor to rotate, thus causing the steel formwork to rotate. Under the action of the centrifugal force generated by the rotation, a hollow cement pole is formed and gradually solidifies. To accelerate this solidification process, the steam generated by the boiler can be used to promote the denaturation structure of the cement after the rotation process ends;

[0003] After the steel bars are loaded into the steel formwork of the concrete pole, it is necessary to fix the two steel formworks. Most of the existing steel formworks for concrete poles are fixed by multiple groups of fixing screws during fixation, which is troublesome, time-consuming, laborious, and has poor practicability.

[0006] A first docking part is provided on the right side of the lower mold base, a second docking part is provided on the right side of the upper mold base, and a third docking part is provided above the second docking part;

[0007] The first docking part is provided with a first inner groove, the second docking part is provided with a second inner groove, the first inner groove is communicated with the second inner groove, the end of the buckling rod is hinged to the first docking part, and the locking rod is sleeved on the top end of the buckling rod so that the locking rod can rotate around the buckling rod;

[0008] The buckling rod rotates and accesses the first inner groove and the second inner groove, and the locking rod exposes outside the second inner groove; the third docking part is provided with a connection hole, the end of the locking rod is provided with a plug, and the locking rod rotates to insert the plug into the connection hole;

[0009] Cone-shaped ends respectively extend from the upper and lower ends of the plug. A pressing part is provided in the connection hole, and the pressing part is connected to the inside of the connection hole through a spring, so that the pressing part has elasticity, and the pressing part is pushed by the spring to keep in contact with the cone-shaped end entering the connection hole.

[0010] Preferably, anti-slip lines are provided on the end faces of both the pressing part and the cone-shaped end.

[0011] Preferably, the pressing parts are respectively provided at the upper and lower ends of the connection hole, and the pressing parts are respectively provided on both sides of the connection hole.

[0012] Preferably, the length of the fastening rod is greater than the total length of both the first inner groove and the second inner groove.

[0013] Preferably, the first inner groove is provided at the edge of the first docking portion, the first inner groove penetrates through the first docking portion, and the first inner groove has an open side for the fastening rod to rotate and insert; the second inner groove is provided at the edge of the second docking portion, the second inner groove penetrates through the second docking portion, and the second inner groove has an open side for the fastening rod to rotate and access.

[0016] The beneficial effects of the present invention compared with the background technology:

[0017] The present invention provides a green and environment-friendly concrete pole steel mold. By connecting the third docking portion with the fastening rod, the upper mold base and the lower mold base can be fastened together. At the same time, the plug is in contact with the pressing member in the socket. As the centrifugal force of the steel mold increases during rotation, the plug has a tendency to move towards the end of the socket. Since the plug is conical, the pressing member in contact with the plug will be correspondingly pressed harder, strengthening the frictional force and improving the connection firmness between the locking rod and the third docking portion. The faster the rotation, the better the connection firmness. It has the advantages of simple structure, compact cooperation, and reasonable design; therefore, it is a product with excellent technical and economic performance.

[0026] A preferred embodiment provided by the present invention is as follows: Figures 1 to 5 As shown, a steel mold for a green environmental protection concrete electric pole includes an upper mold base 1, a lower mold base 2, a buckling rod 3, and a locking rod 4. The left sides of the upper mold base 1 and the lower mold base 2 are hinged.

[0027] A first docking portion 21 is provided on the right side of the lower mold base 2, a second docking portion 11 is provided on the right side of the upper mold base 1, and a third docking portion 12 is provided above the second docking portion 11.

[0028] The first docking portion 21 is provided with a first inner groove 22, the second docking portion 11 is provided with a second inner groove 13, the first inner groove 22 communicates with the second inner groove 13, the end of the buckling rod 3 is hinged to the first docking portion 21 through a shaft rod, and the locking rod 4 is sleeved on the top of the buckling rod 3 so that the locking rod 4 can rotate around the buckling rod 3.

[0029] The buckling rod 3 rotates and accesses the first inner groove 22 and the second inner groove 13. The length of the buckling rod 3 is greater than the total length of the first inner groove 22 and the second inner groove 13, so that the locking rod 4 protrudes out of the second inner groove 13. The third docking portion 12 is provided with a receiving hole 14, the end of the locking rod 4 is provided with a plug 41, the locking rod 4 rotates to insert the plug 41 into the receiving hole 14, and an arc position 43 is provided at the access end of the plug 41 so that the plug can smoothly enter the receiving hole.

[0030] The top end of the buckling rod 3 is provided with an end head 32 and a limiting block 33. The end head 32 and the limiting block 33 are spaced apart to reserve a position for the locking rod 4. The diameter of the end head 32 is larger than that of the buckling rod 3. The limiting block 33 is arranged on the end face of the buckling rod 3. The end of the locking rod 4 is provided with a through hole for the buckling rod 3 to pass through. The locking rod 4 is arranged between the end head 32 and the limiting block 33 to limit the position of the locking rod 4.

[0031] Conical ends 42 extend from the upper and lower ends of the plug 41 respectively. A pressing member 15 is arranged in the connection hole 14. The pressing member 15 is connected in the connection hole 14 through a spring 16, so that the pressing member 15 has elasticity, and the pressing member 15 is pushed by the spring 16 to keep in contact with the conical end 42 entering the connection hole 14. Anti-slip lines are arranged on the end face of the pressing member 15 and the end face of the conical end 42 to increase the friction force.

[0032] The pressing members 15 are respectively arranged at the upper and lower ends of the connection hole 14, and the pressing members 15 are respectively arranged on both sides of the connection hole 14 to correspondingly press the conical ends 42 arranged up and down of the plug 41. The first inner groove 22 is arranged at the edge of the first docking part 21. The first inner groove 22 penetrates through the first docking part 21. The first inner groove 22 has an open side for the buckling rod 3 to rotate and embed; the second inner groove 13 is arranged at the edge of the second docking part 11. The second inner groove 13 penetrates through the second docking part 11. The second inner groove 13 has an open side for the buckling rod 3 to rotate and access. The first inner groove 22 and the second inner groove 13 are located on the same vertical line so that the buckling rod 3 can rotate and access the first inner groove 22 and the second inner groove 13 at the same time.

[0033] Operation process: After putting the steel bars and the mixed concrete into the steel mold (i.e., the upper mold base 1 and the lower mold base 2), cover the upper mold base 1 and the lower mold base 2, turn the buckling rod 3 of the first inner groove 22 so that the buckling rod 3 accesses the first inner groove 22 and the second inner groove 13 at the same time, and at this time the locking rod 4 exposes from the second inner groove 13. The plug 41 of the locking rod 4 and the third docking part 12 are on the same horizontal plane. Rotate the locking rod 4 to insert the joint into the connection hole 14, and limit the locking rod 4 from detaching from the third connection part through the connection between the pressing member 15 and the plug 41, so as to keep the upper mold base 1 and the lower mold base 2 connected. Further, the running wheel drives the electric pole steel mold to rotate. The upper and lower ends of the plug 41 are conical. As the centrifugal force of the steel film increases during rotation, the plug 41 has a tendency to move towards the end of the connection hole 14. Since the plug 41 is conical, the pressure on the pressing member 15 connected to the plug 41 will also increase correspondingly, strengthening the friction force and improving the connection firmness between the locking rod 4 and the third docking part 12. The faster the rotation, the better the connection firmness.
