Description

Technical Field

[0001] The invention relates to a prefabricated concrete enclosure pier, belonging to the technical field of power distribution line equipment. Background Art

[0002] Traditional cast-in-place concrete piers require a series of complex processes such as template installation, steel bar binding, concrete pouring and maintenance on site. The construction period is long, and the poles cannot be protected in a timely and effective manner. Concrete production consumes a large amount of raw materials such as cement, which will cause certain environmental pollution during the construction process. If the cast-in-place concrete pier is broken or damaged during use, it needs to be maintained and replaced. Due to the characteristics of concrete materials, maintenance work is often time-consuming and laborious, and the subsequently dismantled concrete piers can no longer be used, resulting in a waste of resources.

[0003] A recycled concrete pole disclosed in a Chinese utility model patent with publication number CN218862247U includes a precast pier, a first frame is fixedly connected to the top of the precast pier, a second frame is fixedly connected to the top of the first frame, a third frame is fixedly connected to the top of the second frame, a fixed rod is fixedly connected to the top of the third frame, and a lightning rod is provided on the top of the fixed rod.

[0004] The above reference example is provided with prefabricated piers, but the prefabricated piers are still an integrated structure and cannot be disassembled and reused, and concrete needs to be poured in the first pouring hole connecting the prefabricated pier and the pole. When the pole needs to be replaced later, the prefabricated pier and the pole must be forcibly destroyed as a whole, which is time-consuming and labor-intensive. Therefore, improvements are urgently needed. Summary of the invention

The installation process is simple and quick, which greatly shortens the construction period. It is also easy to disassemble and can be recycled.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] Furthermore, the steel mesh includes a plurality of stirrups and a plurality of longitudinal bars, the stirrups are spaced from top to bottom, the longitudinal bars are vertically arranged along the length direction of the stirrups, and the longitudinal bars are fixedly connected to the stirrups.

[0009] Furthermore, a plurality of iron wires are fixedly connected between the steel mesh and the foam layer.

[0010] Furthermore, a plurality of clamps are provided at intervals from top to bottom on the outside of the pier body, and the clamps include two semicircular semicircular hoops detachably connected to each other, and a lifting mechanism for driving each clamp to rise synchronously is provided on the side away from each other of the two semicircular hoops.

[0011] Furthermore, the lifting mechanism comprises a guide rod and a lifting plate, and the guide rod is arranged in the same direction as the electric pole;

[0012] The guide rod is vertically connected to a plurality of transverse rods, and two sides of the guide rod are symmetrically provided with slide rods slidably mounted on the transverse rods, and the top of the guide rod is provided with a driving assembly for driving the two slide rods to alternately reciprocate;

[0013] The lifting plate is slidably installed on the side of the guide rod close to the pole, and a plurality of one-way teeth are arranged on both sides of the lifting plate from top to bottom. Push rods are hinged on the side of the two sliding rods close to the pole, and the free ends of the two push rods are respectively clamped on the one-way teeth on both sides of the lifting plate.

[0014] Furthermore, the driving assembly includes a forward and reverse motor installed on the top of the guide rod, the output shaft of the forward and reverse motor is fixedly connected to a swing rod, the two ends of the swing rod are symmetrically hinged with hinged rods, and the free ends of the two hinged rods are respectively hinged to the top of two sliding rods; the forward and reverse motor is externally connected to a host computer.

[0015] Furthermore, a guide groove parallel to the guide rod is provided in the middle of the lifting plate, and a plurality of clamping blocks are fixedly installed from top to bottom on one side of the guide rod close to the electric pole, and each of the clamping blocks is slidably clamped in the guide groove.

[0016] Furthermore, a plurality of pairs of linkage rods are fixedly installed from top to bottom on one side of the lifting plate close to the pole, and the free ends of each pair of linkage rods are fixedly connected to each clamp in a one-to-one correspondence.

[0017] Furthermore, a fixing collar is fixedly sleeved on the pole, two connecting rods are fixedly connected to the fixing collar, and the free ends of the two connecting rods are fixedly connected to the top ends of the two guide rods respectively.

[0018] Furthermore, each of the clamps is equipped with a tilt sensor for detecting whether the pole is tilted.

[0019] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0020] 1. The present invention can be prefabricated inside the factory by setting up the splicing unit, which effectively reduces the on-site construction time and labor demand and improves the construction efficiency. The prefabricated splicing unit can be directly transported to the site for installation, and the installation process is simple and quick, which can greatly shorten the construction period. The setting of the foam layer can effectively reduce the weight of the splicing unit, which is not only convenient for transportation but also can reduce the workload during installation. The setting of the outer sleeve can provide good protection for the pole. The mutual cooperation between the foam layer and the outer sleeve can effectively improve the impact resistance and durability of the pole. The setting of the steel mesh, anchor steel bars and iron wire ensures the firm connection between the outer sleeve and the foam layer, and improves the stability and durability of the overall structure.

[0021] 2. The present invention provides a lifting mechanism, and when the tilt sensor detects that the pole is tilted, the upper computer controls the two forward and reverse motors to perform periodic forward and reverse rotation. When the forward and reverse motors are reversed, the two ends of the swing rod are driven to swing up and down, and the two slide bars are driven to move up and down during the swinging process of the swing rod. Since a push rod is hingedly installed on the slide bar, the free end of the push rod will move downward and engage with the next one-way tooth after lifting a one-way tooth during the up and down movement of the slide bar. After the swing rod repeatedly swings up and down, the lifting plate can be continuously lifted up by the push rod, thereby driving the lifting of the clamp through the lifting of the lifting plate. When the pole is tilted, the position of the clamp can be adjusted so that the clamp can still maintain a good clamping of the splicing unit, thereby ensuring that the splicing unit can well protect the tilted pole. At the same time, the adjustable design of the clamp can also help reduce further damage that may be caused by the tilt of the pole, that is, by timely adjusting the position of the clamp, the shear force or pressure on the pole due to the tilt can be prevented from being too large, thereby protecting the structural integrity of the pole and extending its service life.

[0037] Furthermore, a plurality of iron wires 5 are fixedly connected between the steel mesh 3 and the foam layer 2 .

[0038] Embodiment 2

[0039] See also Figures 5 to 9 A plurality of clamps 6 are provided on the outside of the pier body from top to bottom at intervals. The clamps 6 include two semicircular semicircular hoops that are detachably connected to each other. A lifting mechanism 7 for driving each clamp 6 to rise synchronously is provided on one side of the two semicircular hoops that are away from each other.

[0040] Furthermore, the lifting mechanism 7 includes a guide rod 8 and a lifting plate 18, and the guide rod 8 and the electric pole 19 are arranged in the same direction;

[0041] A plurality of transverse rods are vertically connected to the guide rod 8. Slide rods 11 slidably mounted on the transverse rods are symmetrically arranged on both sides of the guide rod 8. A driving assembly for driving the two slide rods 11 to alternately reciprocate is arranged at the top of the guide rod 8. In this embodiment, two transverse rods are arranged, namely an upper transverse rod 9 and a lower transverse rod 10. The upper transverse rod 9 is arranged at a position close to the top of the guide rod 8, and the lower transverse rod 10 is arranged at the bottom of the guide rod 8.

[0042] The lifting plate 18 is slidably installed on the side of the guide rod 8 close to the pole 19, and a plurality of one-way latch teeth 182 are provided on both sides of the lifting plate 18 from top to bottom. The two sliding rods 11 are hinged with push rods 12 on one side close to the pole 19, and the free ends of the two push rods 12 are respectively clamped on the one-way latch teeth 182 on both sides of the lifting plate 18.

[0043] Furthermore, the driving assembly includes a forward and reverse motor 13 installed on the top of the guide rod 8, the output shaft of the forward and reverse motor 13 is fixedly connected to a swing rod 15, and the two ends of the swing rod 15 are symmetrically hinged with hinge rods 14, and the free ends of the two hinge rods 14 are respectively hinged to the top of the two sliding rods 11; the forward and reverse motor 13 is externally connected to the upper computer.

[0044] Furthermore, a guide groove 181 parallel to the guide rod 8 is opened in the middle of the lifting plate 18 , and a plurality of blocks 21 are fixedly installed from top to bottom on one side of the guide rod 8 close to the electric pole 19 , and each block 21 is slidably clamped in the guide groove 181 .

[0045] Furthermore, a plurality of pairs of linkage rods 20 are fixedly installed from top to bottom on one side of the lifting plate 18 close to the electric pole 19 , and the free ends of each pair of linkage rods 20 are fixedly connected to each clamp 6 in a one-to-one correspondence.

[0046] Furthermore, a fixing collar 16 is fixedly sleeved on the electric pole 19 , and two connecting rods 17 are fixedly connected to the fixing collar 16 . The free ends of the two connecting rods 17 are fixedly connected to the top ends of the two guide rods 8 , respectively.

[0047] Furthermore, each clamp 6 is equipped with a tilt sensor for detecting whether the pole 19 is tilted. The tilt sensor is externally connected to a host computer. The host computer receives a tilt signal detected by the tilt sensor and then controls the forward and reverse motor 13 to start.

[0048] From the above description, it can be seen that when the tilt sensor detects that the pole 19 is tilted, the upper computer controls the two forward and reverse motors 13 to perform periodic forward and reverse rotations. When the forward and reverse motors 13 are reversed, the two ends of the swing rod 15 will be driven to swing up and down. During the swinging process of the swing rod 15, the two slide bars 11 will be driven to move up and down. Since the push rod 12 is hingedly installed on the slide bar 11, the free end of the push rod 12 will move downward and engage with the next one-way tooth 182 after lifting a one-way tooth 182 during the up and down movement of the slide bar 11. After the swing rod 15 repeatedly swings up and down, the lifting plate 18 can be continuously lifted upward by the push rod 122, thereby driving the lifting of the clamp 6 by the lifting of the lifting plate 18. When the pole 19 is tilted, the position of the clamp 6 can be adjusted so that the clamp 6 can still maintain a good clamping of the splicing unit.

[0049] The working principle of the present invention: by setting up splicing units, prefabrication can be carried out inside the factory, which effectively reduces the on-site construction time and labor requirements and improves the construction efficiency. The prefabricated splicing units can be directly transported to the site for installation, and the installation process is simple and quick, which can greatly shorten the construction period. By setting up the foam layer, the mass of the splicing unit can be effectively reduced, which is not only convenient for transportation, but also can reduce the workload during installation. The setting of the outer sleeve can provide good protection for the pole. The mutual cooperation between the foam layer and the outer sleeve can effectively improve the impact resistance and durability of the pole. The setting of the steel mesh, anchor steel bars and iron wire ensures a firm connection between the outer sleeve and the foam layer, and improves the stability and durability of the overall structure.

[0050] By setting a lifting mechanism, when the tilt sensor detects that the pole is tilted, the upper computer can control the two forward and reverse motors to perform periodic forward and reverse rotation. When the forward and reverse motors are reversed, the two ends of the swing rod will be driven to swing up and down, and the two slide bars will be driven to move up and down during the swinging process of the swing rod. Since a push rod is hingedly installed on the slide bar, the free end of the push rod will move downward and get stuck in the next one-way tooth after lifting a one-way tooth during the up and down movement of the slide bar. After the swing rod repeatedly swings up and down, the lifting plate can be continuously lifted up by the push rod, so that the lifting of the lifting plate drives the lifting of the clamp. When the pole is tilted, the position of the clamp can be adjusted so that the clamp can still keep the splicing unit well clamped, thereby ensuring that the splicing unit can well protect the tilted pole. At the same time, the adjustable design of the clamp can also help reduce the further damage that may be caused by the tilt of the pole, that is, by timely adjusting the position of the clamp, the shear force or pressure on the pole due to the tilt can be prevented from being too large, thereby protecting the structural integrity of the pole and extending its service life.
