Description

Technical Field

[0001] The invention relates to the field of cement pole production equipment, and in particular to a cement pole assembly clamping bracket and a use method thereof. Background Art

[0002] As an outdoor power transmission and distribution infrastructure, cement poles are extremely common in all kinds of geographical environments. Multi-section assembled cement poles are prefabricated structures that can be prefabricated in factories and transported to the construction and installation area in sections, which can reduce the difficulty and cost of transportation. The assembled structure can reduce the time for on-site pouring and maintenance, and speed up the construction progress. At the same time, segmented assembly also facilitates the use of mechanically assisted construction, further improving efficiency. If a segment is damaged in subsequent use, the segment can be replaced separately without replacing the entire pole, which reduces the cost of maintenance and replacement. Therefore, segmented cement poles have been widely used;

[0003] However, since the cement pole is thick at the root and thin at the tip after overall assembly, each segment is a tapered slender frustum-shaped structure, and since adjacent segments are mostly connected by end flanges, the flanges are directly connected to the internal steel skeleton and embedded in the end face when the cement pole is cast. However, in order to meet the taper requirements, the thickness of the two ends of the casting cavity of the current cement pole is inconsistent, and it is impossible to ensure that the internal skeleton and the end face flange are in a coaxial position with the mold. In addition, during the casting process, the flange is easily non-parallel to the end face of the mold due to the pressure of the concrete, which causes the connection after the subsequent cement pole segments are assembled to tilt. The subsequent pole may not be able to withstand the load of the erection line in the outward deflection state, posing a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to provide a cement pole assembly clamping bracket and a method of using the same in order to solve the above-mentioned problem.

The shaft tube transversely passes through the sealing sleeve and is sealed with the sealing sleeve, and the outer end of the sealing sleeve extends into the assembly hole and is threadedly engaged with the assembly hole.

[0010] Preferably, a transmission plate is fixed to the outer end face of the transmission frame, a core hole for accommodating the shaft tube is transversely penetrated through the middle of the transmission frame, and external connecting holes distributed around the shaft tube are transversely penetrated through the end face of the transmission frame, and a laterally extending positioning pin is fixed to the end face of the transmission frame outside the external connecting hole.

[0011] Preferably, an inner connecting hole is passed through the end surface of the flange corresponding to the outer connecting hole, and a positioning hole for inserting and cooperating with the positioning pin is passed through the outside of the flange horizontally.

[0012] Preferably, the support ring is welded and fixed to the transmission frame, a rotating groove for supporting the rotation of the locking frame is coaxially arranged on the inner side of the support ring, and a hinge column is arranged around one side of the support ring close to the locking frame, and the hinge column corresponds to the centering arm one by one.

[0013] Preferably, a laterally extending pressure-bearing column is fixed on the support ring on the outside of the hinged column, the pressure-bearing column corresponds to the distribution of the electric cylinder, the locking frame includes two groups of mutually parallel synchronous rings, a transmission column is laterally connected between the two groups of synchronous rings, and the transmission column corresponds one-to-one to the electric cylinder.

[0014] Preferably, the outer end of the electric cylinder is hinged to the pressure-bearing column, and the inner end of the electric cylinder is hinged to the transmission column, a constraint hole is horizontally passed through the two groups of the synchronous rings, the centering arm includes a sliding rod hinged on the hinged column, a sliding sleeve is provided on the middle section of the sliding rod, the sliding sleeve is slidably matched with the sliding rod, and a constraint shaft is fixed to the outside of the sliding sleeve, which penetrates into the constraint hole and rotates with the constraint hole.

[0016] The method for using the cement pole assembly clamping bracket comprises the following steps:

[0017] a. First, place the lower mold between the two sets of frames, and support the lower mold through multiple sets of centering arms distributed in a ring shape. At the same time, place two sets of flanges at both ends of the lower mold to ensure that the positioning holes of the flanges are plugged and positioned with the positioning pins on the transmission frame. At the same time, screw the sealing sleeve into the flange to fix the sealing sleeve to the transmission frame through the assembly hole. Then, extend the steel strands for making the inner skeleton of the cement rod into the mold along the outer connecting holes of the transmission frame and the inner connecting holes of the flange. The steel strands pass through the two sets of transmission frames in sequence to form a cement rod casting skeleton through multiple strands of steel strands.

[0018] b. After the cement pole skeleton is arranged, the upper mold is hoisted to the top surface of the lower mold, and the bolts are inserted through the assembly frame to complete the mold assembly. Then, the telescopic end of the electric cylinder is contracted, and then, under the support of the support ring, the electric cylinder is used to pull the locking frame to rotate as a whole. The telescopic end of the electric cylinder pulls the transmission column, and the constraint shaft support sleeve inserted into the constraint hole on the locking frame moves toward the hinge column. At this time, the sliding sleeve is used to drive the sliding rod to rotate toward the axis of the locking frame with the hinge column as the center of the circle, so that when the electric cylinder drives the locking frame to rotate, multiple sets of centering arms are supported to gather toward the center, so as to achieve clamping of both ends of the mold and axis positioning, and ensure that the axes of the mold, flange and transmission frame coincide.

[0019] c. After the mold is clamped, connect the external grouting joint of the shaft tube to the concrete pumping equipment, and send the concrete into the mold through the grouting hole along the shaft tube. At the same time, use the drive motor to drive the transmission frame, support ring, locking frame, centering arm, electric cylinder, flange and mold to rotate synchronously, and then complete the concrete rotation centrifugal action synchronously during the process of concrete entering the mold, so as to promote the uniform distribution of concrete in the mold;

[0020] d. After the concrete pouring is completed, the shaft tube is pulled outward, and the mold is kept in a suspended support state using a lifting device. Then, multiple sets of electric cylinders are released, and the locking frame is driven to rotate in the opposite direction by extending the telescopic end of the electric cylinder, thereby supporting multiple sets of centering arms to rotate outward and expand, releasing the clamping and tightening effect of multiple sets of centering arms on the mold, and then the mold and the two sets of flanges on its end faces are lifted up synchronously, so as to transfer the mold containing semi-formed concrete and the flange to the steam station for subsequent maintenance.

[0021] The beneficial effects are as follows: 1. The present invention provides multiple groups of centering arms distributed around the locking frame, uses the centering arms to support both ends of the mold, cooperates with the locking frame through the support ring, and uses the electric cylinder to drive the support ring to rotate in the locking frame, which can synchronously control the outward expansion and inward retraction angles of multiple groups of centering arms, so as to adapt to the clamping of molds with different tapers, ensure that the mold, flange and transmission frame remain in a coaxial state, thereby avoiding the problem that the existing casting equipment cannot keep the flange coaxial with the pole, and ensure the consistency of the axis at the assembly connection of adjacent pole segments;

[0022] 2. An axial tube is provided to extend into the mold for concrete filling, which can deliver concrete to the mold cavity in the mold closing state, avoiding the cumbersome operation of first delivering concrete to the lower mold and then hoisting the upper mold to close the mold. It can also be filled with more concrete to ensure the density of the pole structure, avoid the problem of easy spillage of materials in the existing concrete pouring method, reduce the process of wiping the material on the top of the lower mold, and speed up the production.

[0023] 3. A driving motor for driving the transmission frame to rotate is arranged on the outside of the frame, which can control the rotation of the transmission frame, support ring, locking frame, electric cylinder, centering arm, flange and mold while using the shaft tube to fill concrete into the mold, promote the homogenization of the concrete filled in the mold, and integrate the centrifugal forming and pouring processes of concrete, eliminating the subsequent production step of lifting the mold to the centrifugal rotation station, and further speeding up the production speed.

[0045] The end surface of the frame 3 is also provided with a guide wheel 302 for supporting the rotation of the transmission frame 4, and the other end of the frame 3 is provided with a motor seat 301 for supporting the drive motor 11, the support ring 5 is welded and fixed to the transmission frame 4, and a rotating groove 501 for supporting the rotation of the locking frame 6 is coaxially provided on the inner side of the support ring 5, and a hinge column 502 is arranged around the side of the support ring 5 close to the locking frame 6, and the hinge column 502 corresponds to the centering arm 7 one by one, and a laterally extending pressure column 503 is fixed on the support ring 5 outside the hinge column 502, and the pressure column 503 is distributed corresponding to the electric cylinder 8, and the locking frame 6 includes two sets of mutually parallel synchronous rings 601, and a transmission column 602 is laterally connected between the two sets of synchronous rings 601, and the transmission column 602 corresponds to the electric cylinder 8 one by one;

[0046] Specifically, the outer end of the electric cylinder 8 is hinged to the pressure column 503, and the inner end of the electric cylinder 8 is hinged to the transmission column 602, so that the synchronous ring 601 can be pushed to rotate under the support of the support ring 5 on the electric cylinder 8.

[0047] The method for using the cement pole assembly clamping bracket comprises the following steps:

[0048] a. Set the two sets of frames 3 above the same ground rail respectively, so as to ensure that the spacing between the two sets of frames 3 is adjustable, so as to facilitate the subsequent separation of the mold 1 from the centering arms 7 on both sides, first place the lower mold 102 between the two sets of frames 3, and support the lower mold 102 through multiple sets of centering arms 7 distributed in a ring shape, and at the same time place two sets of flanges 9 at the two end positions in the lower mold 102, ensure that the positioning holes 902 of the flanges 9 are plugged and positioned with the positioning pins 403 on the transmission frame 4, and at the same time screw the sealing sleeve 10 into the flange 9 to fix the sealing sleeve 10 to the transmission frame 4 through the assembly hole 402, and then extend the steel strands for making the inner skeleton of the cement rod into the mold 1 along the outer connecting holes 404 of the transmission frame 4 and the inner connecting holes 901 of the flange 9, and the steel strands sequentially pass through the two sets of transmission frames 4 to form a cement rod casting skeleton through multiple strands of steel strands;

[0049] b. After the cement pole skeleton is arranged, the upper mold 101 is hoisted to the top surface of the lower mold 102, and the bolts are inserted through the assembly frame 103 to complete the assembly of the mold 1. Then, the telescopic end of the electric cylinder 8 is contracted, and then, under the support of the support ring 5, the electric cylinder 8 is used to pull the locking frame 6 to rotate as a whole. The telescopic end of the electric cylinder 8 pulls the transmission column 602, and the constraint shaft 704 inserted into the constraint hole 603 on the locking frame 6 supports the sliding sleeve 703 to move toward the hinge column 502. At this time, the sliding sleeve 703 is used to drive the sliding rod 701 to rotate toward the axis direction of the locking frame 6 with the hinge column 502 as the center, so that when the electric cylinder 8 drives the locking frame 6 to rotate, multiple groups of centering arms 7 are supported to gather toward the center, so as to achieve clamping of the two ends of the mold 1 and axis positioning, and ensure that the axes of the mold 1, flange 9 and transmission frame 4 coincide with each other;

[0050] c. After the mold 1 is clamped, the external grouting joint 201 of the shaft tube 2 is connected to the concrete pumping equipment, and the concrete is fed into the mold 1 through the grouting hole 202 along the shaft tube 2. At the same time, the driving motor 11 is used to drive the transmission frame 4, the support ring 5, the locking frame 6, the centering arm 7, the electric cylinder 8, the flange 9 and the mold 1 to rotate synchronously, and then the concrete rotation centrifugal action is synchronously completed during the process of concrete being poured into the mold 1, so as to promote the uniform distribution of concrete in the mold 1;

[0051] d. After the concrete pouring is completed, the shaft tube 2 is pulled outward, and the mold 1 is kept in a suspended supporting state using a lifting device, and then the multiple sets of electric cylinders 8 are loosened, and the locking frame 6 is driven to rotate in the opposite direction by the extension of the telescopic end of the electric cylinder 8, thereby supporting the multiple sets of centering arms 7 to rotate outward and unfold, releasing the clamping and tightening effect of the multiple sets of centering arms 7 on the mold 1, and then the mold 1 and the two sets of flanges 9 on its end faces are synchronously lifted upward to transfer the mold 1 and the flanges 9 containing the semi-formed concrete to the steam station for subsequent maintenance.

[0052] By setting a plurality of groups of centering arms 7 distributed around the locking frame 6, the centering arms 7 are used to support the two ends of the mold 1, and the support ring 5 cooperates with the locking frame 6, and the electric cylinder 8 is used to drive the support ring 5 to rotate in the locking frame 6, the outward expansion and inward retraction angles of the plurality of groups of centering arms 7 can be synchronously controlled, so that the molds 1 with different tapers can be clamped and used, ensuring that the mold 1, the flange 9 and the transmission frame 4 remain in a coaxial state, thereby avoiding the problem that the existing casting equipment cannot keep the flange 9 coaxial with the pole, and ensuring the consistency of the axis at the assembly connection of adjacent pole segments;

[0053] A shaft tube 2 is provided which extends into the mold 1 for concrete filling, and can deliver concrete into the mold cavity in the mold closing state, thereby avoiding the cumbersome operation of first delivering concrete into the lower mold 102 and then hoisting the upper mold 101 to close the mold. In addition, more concrete can be filled to ensure the density of the pole structure, and the problem of easy spillage of materials in the existing concrete pouring method can be avoided, thereby reducing the process of wiping the material on the top mold closing surface of the lower mold 102 and speeding up the production speed.

[0054] A driving motor 11 for driving the transmission frame 4 to rotate is arranged on the outside of the frame 3. The driving motor 11 can control the rotation of the transmission frame 4, the support ring 5, the locking frame 6, the electric cylinder 8, the centering arm 7, the flange 9 and the mold 1 while using the shaft tube 2 to fill the mold 1 with concrete, thereby promoting the homogenization of the concrete filled in the mold 1 and integrating the centrifugal forming and pouring processes of the concrete, thereby eliminating the subsequent production step of lifting the mold 1 to the centrifugal rotation station, and further speeding up the production speed.

[0055] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.

The clamping plate (702) is arc-shaped, and the width of the clamping plate (702) is greater than the distance between the two groups of synchronizing rings (601).

10. The method for using the cement pole assembly clamping bracket according to claim 9, characterized in that: The following steps are involved: a. Firstly, the lower mold (102) is placed between the two sets of frames (3), and the lower mold (102) is supported by a plurality of sets of centering arms (7) distributed in an annular shape. Meanwhile, two sets of flanges (9) are placed at the two end positions in the lower mold (102), and the positioning holes (902) of the flanges (9) are ensured to be plugged and positioned with the positioning pins (403) on the transmission frame (4). Meanwhile, the sealing sleeve (10) is screwed into the flange (9) to fix the sealing sleeve (10) to the transmission frame (4) through the assembly hole (402), and then the steel strands for making the inner skeleton of the cement rod are extended into the mold (1) along the outer connecting holes (404) of the transmission frame (4) and the inner connecting holes (901) of the flanges (9), and the steel strands are sequentially passed through the two sets of transmission frames (4) to form a cement rod casting skeleton through the plurality of steel strands; b. After the cement pole skeleton is arranged, the upper mold (101) is hoisted to the top surface of the lower mold (102), and bolts are inserted through the assembly frame (103) to complete the assembly of the mold (1). Then, the telescopic end of the electric cylinder (8) is contracted, and then, under the support of the support ring (5), the electric cylinder (8) is used to pull the locking frame (6) to rotate as a whole. The telescopic end of the electric cylinder (8) pulls the transmission column (602) and inserts the constraint shaft (704) in the constraint hole (603) on the locking frame (6). ) supports the sliding sleeve (703) to move toward the hinge column (502), and at this time, the sliding sleeve (703) drives the sliding rod (701) to rotate toward the axis of the locking frame (6) with the hinge column (502) as the center, thereby supporting multiple sets of centering arms (7) to gather toward the center during the process of the electric cylinder (8) pushing the locking frame (6) to rotate, thereby achieving clamping of the two ends of the mold (1) and axis positioning, ensuring that the axes of the mold (1), the flange (9) and the transmission frame (4) coincide with each other; c. After the mold (1) is clamped, the external grouting joint (201) of the shaft tube (2) is connected to the concrete pumping equipment, and the concrete is fed into the mold (1) through the grouting hole (202) along the shaft tube (2). At the same time, the driving motor (11) is used to drive the transmission frame (4), the support ring (5), the locking frame (6), the centering arm (7), the electric cylinder (8), the flange (9) and the mold (1) to rotate synchronously, thereby synchronously completing the concrete rotation centrifugal action during the process of concrete being poured into the mold (1), thereby promoting the uniform distribution of the concrete in the mold (1); d. After the concrete pouring is completed, the shaft tube (2) is pulled outward, and the mold (1) is kept in a suspended supporting state using a lifting device, and then the multiple sets of electric cylinders (8) are released, and the locking frame (6) is driven to rotate in the opposite direction by the extension of the telescopic end of the electric cylinder (8), thereby supporting the multiple sets of centering arms (7) to rotate outward and unfold, releasing the clamping and tightening effect of the multiple sets of centering arms (7) on the mold (1), and then the mold (1) and the two sets of flanges (9) on the end faces are synchronously lifted upward, so as to transfer the mold (1) and the flanges (9) containing the semi-formed concrete to the steam station for subsequent maintenance.
