Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pole production, and particularly relates to a concrete pole tensioning and anchoring device. Background Art

[0002] When producing ordinary concrete poles, sheathed holes are used on the tensioning head and tensioning disk, so that the steel bars can pass directly through the sheathed holes and are locked by locking nuts. After locking the steel bars, tensioning equipment is used to tension the steel bars, and finally the tensioning head nuts are locked to put the steel bars in a stretched state. Then, concrete pouring, centrifugation, and curing processes are carried out to form the pole. After the pole is cured and demoulded, the demoulding worker uses a wrench to remove the steel bar locking nuts one by one, and uses a hammer to knock out the steel bars on the tensioning head and tensioning disk, and then uses welding to cut off the steel bars extending out of the large and small end faces of the pole.

[0003] However, the production process of the above-mentioned poles has the following problems: 1. The steel bar hole guards on the tensioning head and the tensioning disk wear out during long-term use, and the hole diameter of the guard becomes larger. After pouring concrete, the concrete slurry is easy to leak from the guard hole, affecting the quality of the pole, and increasing the difficulty of disassembling the tensioning head and the tensioning disk, and increasing the labor intensity of the demoulding workers; 2. Because the steel bars need to pass through the tensioning head and the tensioning disk for locking, the cutting length of the steel bars will be about 100mm longer than the length of the pole, which increases the cost of steel bars; 3. After the pole is demoulded, oxygen cutting is required to cut the steel bar head, which poses a safety hazard and will cause occupational health hazards to the operators; 4. When demoulding, a hammer is needed to knock out the steel bar head from the tensioning head and the tensioning disk. The noise generated by the hammer hitting the tensioning head and the tensioning disk affects the hearing of the demoulding worker, and the hammer is easy to hit the operator's hand when hitting the tensioning head and the tensioning disk, which can easily cause safety accidents and promote the risk of occupational diseases among employees.

[0004] In order to solve the above problems, the existing publication number CN220198070U discloses a steel bar tensioning tool for concrete poles, including a tensioning head and a tensioning disk for use in combination; a plurality of first through holes are evenly distributed in a circle on the end face of the tensioning head, a first sheath is coaxially sleeved in the first through hole, a first anchor bolt is coaxially sleeved in the first sheath, and the end face of the first anchor bolt is flush with the end face of the tensioning head; a plurality of second through holes are evenly distributed in a circle on the end face of the tensioning disk, a second sheath is coaxially sleeved in the second through hole, a second anchor bolt is coaxially sleeved in the second sheath, and the end face of the second anchor bolt is flush with the end face of the tensioning disk; the threaded sections of the first anchor bolt and the second anchor bolt are both internal threads.

[0005] It is known from existing common sense that the diameters at both ends of a concrete pole are different, and their diameters decrease or increase from one end to the other. Therefore, the diameters at both ends of the steel cage inside the concrete pole are also different, and their diameters decrease or increase from one end to the other. In addition, it can also be seen from the drawings of the above-mentioned patent that the diameters at both ends of the steel cage are different, and their diameters decrease or increase from one end to the other. Therefore, the steel bars arranged along the length direction of the steel cage are not perpendicular to the end faces of the tensioning heads and the end faces of the tensioning disks at both ends. However, the end face of the first anchor bolt is flush with the end face of the tensioning head, and the end face of the second anchor bolt is flush with the end face of the tensioning disk, which makes it difficult to align the first anchor bolt and the second anchor bolt with the threaded segments at both ends of the steel bar, and thus makes it inconvenient for the first anchor bolt and the second anchor bolt to be threadedly connected to the threaded segments, or the connection is difficult, or it is impossible to connect. Utility Model Content

[0006] In response to the shortcomings of the prior art, the purpose of the present invention is to provide a concrete pole tensioning and anchoring device. The positional relationship and the inclination angle relationship between the sleeve and the tensioning disk in this application can be adjusted so that the sleeve can be aligned and connected with the threaded sections at both ends of the steel bar. At the same time, the tensioning disk can be suitable for concrete poles of various diameters, and there is no need to adapt to tensioning disks of various sizes.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A concrete pole tensioning and anchoring device, comprising:

[0009] A tensioning disk, wherein a plurality of evenly distributed chute grooves are formed on the tensioning disk along its circumference, wherein a slider is slidably connected in the chute, and a first ball head is rotatably connected in the middle of the slider;

[0010] A connecting rod passes through the first ball head and is slidably connected to the first ball head. One end of the connecting rod is fixedly connected to a sleeve, and an internal thread is provided on the inner side of the sleeve. The other end of the connecting rod is fixedly connected to the second ball head, and a baffle is rotatably connected to the second ball head.

[0011] The above technical solution, its principle and technical effects:

[0012] First, erect the tensioning disk so that the sleeve faces upward. Under the action of gravity, the sleeve approaches the tensioning disk. Finally, adjust the posture of the tensioning disk so that the sleeve faces the threaded section at the end of the steel bar. Bend the connecting rod to drive the first ball head to rotate, adjust the position and inclination angle of the sleeve so that the sleeve is aligned with the threaded section at the end of the steel bar, screw the sleeve onto the threaded section at the end of the steel bar, and the remaining sleeves are threadedly connected to the threaded sections at the end of the steel bar in turn. When all the sleeves are tightened with the threaded sections at the end of the steel bar, the tensioning disk can be pulled by the pulling equipment. During the movement of the tensioning disk, the steel bar is straightened until the baffle is in contact with the end face of the tensioning disk. Since the baffle can rotate, it is completely in contact with the end face of the tensioning disk, so that the baffle is subjected to balanced force.

[0013] In a preferred example, the present invention can be further configured as follows: concave limiting grooves are provided on both sides of the interior of the sliding groove, and both sides of the sliding block are located in the limiting grooves and slide.

[0014] In a preferred example, the present invention can be further configured as follows: the outer side of the sleeve is an external hexagonal structure.

[0015] In a preferred example, the present invention can be further configured as follows: the diameter of the baffle is greater than the width of the chute.

[0016] In a preferred example, the present invention can be further configured as follows: a pull rod is fixedly connected to a side surface of the tensioning disk close to the baffle.

[0017] In a preferred example, the present invention can be further configured as follows: the pull rod and the tensioning disk are arranged coaxially.

[0018] In a preferred example, the present invention can be further configured as follows: the other end of the pull rod is fixedly connected to a pull ring.

[0019] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0020] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0021] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting, and tenoning. Since they require forging, sawing, or oxygen cutting to disassemble during repair or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration, polishing, etc.).

[0023] A threaded connection refers to a detachable connection in which the connected parts are connected together using a threaded part (or the threaded part of the connected parts).

[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] Beneficial effects of the utility model:

[0027] The positional relationship and inclination angle relationship between the sleeve and the tensioning disk in this application can be adjusted so that the sleeve can be aligned and connected with the threaded sections at both ends of the steel bar. At the same time, the tensioning disk can be suitable for concrete poles of various diameters without the need to adapt to tensioning disks of various sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] According to the concept of this application, Figures 1 to 4 An embodiment of a concrete pole tensioning and anchoring device is described below. Specifically, the concrete pole tensioning and anchoring device is constructed as a split structure, which includes a tensioning plate 1, a connecting rod 4, a sleeve 5, a baffle 7 and other components. Through the mutual cooperation of the provided slide groove 11, slider 2, first ball head 3, second ball head 6 and other structures, the tensioning disk 1 is first erected so that the sleeve 5 faces upward. Under the action of gravity, the sleeve 5 approaches the tensioning disk 1. Finally, the posture of the tensioning disk 1 is adjusted so that the sleeve 5 faces the threaded section at the end of the steel bar. The connecting rod 4 is bent to drive the first ball head 3 to rotate, and the position and inclination angle of the sleeve 5 are adjusted so that the sleeve 5 is aligned with the threaded section at the end of the steel bar. The sleeve 5 is screwed on the threaded section at the end of the steel bar, and the remaining sleeves 5 are threadedly connected to the threaded section at the end of the steel bar in turn. When all the sleeves 5 are tightened with the threaded section at the end of the steel bar, the tensioning disk 1 can be pulled by the pulling equipment. During the movement of the tensioning disk 1, until the baffle 7 is in contact with the end face of the tensioning disk 1, the steel bar is straightened. Since the baffle 7 can rotate, the baffle 7 is completely in contact with the end face of the tensioning disk 1, so that the baffle 7 is subjected to balanced force.

[0036] like Figure 1-4 As shown, a concrete pole tensioning anchoring device includes:

[0037] A tensioning plate 1 is provided with a plurality of evenly distributed chute grooves 11 along its circumference, a slider 2 is slidably connected in the chute 11, and a first ball head 3 is rotatably connected in the middle of the slider 2;

[0038] The connecting rod 4 passes through the first ball head 3 and is slidably connected to the first ball head 3. One end of the connecting rod 4 is fixedly connected to a sleeve 5, and an internal thread 51 is provided on the inner side of the sleeve 5. The other end of the connecting rod 4 is fixedly connected to the second ball head 6, and a baffle 7 is rotatably connected to the second ball head 6.

[0039] When in use, first erect the tensioning disk 1 so that the sleeve 5 faces upward. Under the action of gravity, the sleeve 5 approaches the tensioning disk 1. Finally, adjust the posture of the tensioning disk 1 so that the sleeve 5 faces the threaded section at the end of the steel bar. Bend the connecting rod 4 to drive the first ball head 3 to rotate, adjust the position and inclination angle of the sleeve 5 so that the sleeve 5 is aligned with the threaded section at the end of the steel bar, screw the sleeve 5 on the threaded section at the end of the steel bar, and the remaining sleeves 5 are threadedly connected to the threaded section at the end of the steel bar in turn. When all the sleeves 5 are tightened with the threaded section at the end of the steel bar, the tensioning disk 1 can be pulled by the pulling equipment. During the movement of the tensioning disk 1, until the baffle 7 is in contact with the end face of the tensioning disk 1, the steel bar is straightened. Since the baffle 7 can rotate, the baffle 7 is completely in contact with the end face of the tensioning disk 1, so that the baffle 7 is subjected to balanced force.

[0040] In one embodiment of the present invention, concave limiting grooves 12 are provided on both sides of the inner portion of the chute 11, and both sides of the slider 2 slide in the limiting grooves 12. This design ensures that the slider 2 will not fall out of the chute 11 when sliding in the chute 11.

[0041] In one embodiment of the present invention, the outer side of the sleeve 5 is an outer hexagonal structure. Such a design makes it convenient for the operator to tighten the sleeve 5 on the threaded section of the end of the steel bar with a handheld wrench to achieve anchoring with the steel bar.

[0042] In one embodiment of the present invention, the diameter of the baffle 7 is greater than the width of the chute 11. When all sleeves 5 are connected to the steel bars and the tensioning disk 1 is pulled, the baffle 7 fits with the tensioning disk 1 to prevent the connecting rod 4 from separating from the first ball head 3.

[0043] In one embodiment of the present invention, a pull rod 8 is fixedly connected to one side of the tensioning disc 1 near the baffle 7. The setting of the pull rod 8 is conducive to connecting with the pulling device to pull the tensioning disc 1.

[0044] In one embodiment of the present invention, the pull rod 8 is coaxially arranged with the tensioning disk 1. Such a design enables the connecting rods 4 at various locations to be subjected to balanced forces when the tensioning disk 1 is pulled.

[0045] In one embodiment of the present invention, the other end of the pull rod 8 is fixedly connected to a pull ring 9. The arrangement of the pull rod 9 further highlights the convenience of connection with the pulling device.

[0046] The following further describes a concrete pole tensioning and anchoring device provided by the present invention in conjunction with the accompanying drawings and implementation methods.
