Description

Technical Field

[0001] The present invention relates to the technical field of electric power poles, and in particular to an intelligent cement pole reinforcement and slurry retaining device and a use method thereof. Background Art

[0002] Currently, the main structure of cement poles is a prefabricated hollow ring-shaped concrete pole with a steel frame in the middle and high-strength concrete around the perimeter. The specific production steps are: making the steel cage - adding baffles at both ends - pouring - closing the mold - centrifugal compaction - steam curing - demoulding - quality inspection - field curing - and then leaving the factory.

[0003] Currently, the technology for concrete mix design, reinforcement cage binding, and curing is relatively mature. However, during the centrifugal stage, as the steel bars pass through the baffle, the current technology is to prevent the steel bars from being ejected due to centrifugal force during high-speed rotation. A pier head machine is used to hot-melt-form pier heads at both ends of the steel bars, which are then clamped to the baffle. This prevents the steel bars from being ejected during centrifugation or when using a pump.

[0004] However, the production of the pier head requires heating, melting, and cooling the steel bars, which is a relatively demanding process for the workers. This process also changes the internal force distribution of the steel bars, leading to stress concentration at the pier head. Since the steel bars are not completely parallel in the mold, the force is uneven, causing the pier head to break, thus losing its binding function. When using a high-speed pump to pump concrete into the mold, or using a high-speed centrifuge, the steel bars may be ejected from the mold through the baffle, causing personal injury.

[0005] Moreover, since the holes of the baffle are larger than the steel bars, it is convenient for the steel bars to pass through. During the centrifugation stage, the slurry will flow out of the holes in large quantities under high-speed centrifugation, thereby polluting the environment or causing excessive water in the concrete to be thrown out, resulting in a decrease in the water-cement ratio, causing the finished product strength to differ too much from the design strength, and a decrease in the yield rate. Summary of the Invention

[0006] One of the technical problems to be solved by the present invention is to provide an intelligent cement pole reinforcement and slurry retaining device to solve the technical problems in the above-mentioned background technology.

[0007] The technical solution of the present invention is:

[0008] An intelligent cement pole reinforcement and slurry retaining device comprises a main body, a top plate, a bottom plate and an outer shell, wherein the main body is cylindrical and a flange is installed at the front end; the bottom plate is welded to the rear end of the main body, the top plate is located inside the main body and slides, and a plurality of sealing sleeves are arranged in a circular array on the front end surface of the top plate; a wireless force sensor is installed between the top plate and the bottom plate, and the wireless force sensor is fixed to the bottom plate; a plurality of rectangular drainage grooves are provided at equal angles on the peripheral wall of the main body, and water retaining plates are fixed on the inner side of the top plate at the positions corresponding to the rectangular drainage grooves; the outer shell is concentrically mounted on the outer periphery of the main body through a sealed bearing, and the rear end of the shell is closed, and a drainage outlet is provided at the bottom; a touch screen and an alarm are installed on the outer wall of the shell, and a battery compartment is installed on the bottom side as a counterweight to supply power to the touch screen and the alarm; the wireless force sensor is independently powered and transmits data to the touch screen and the alarm wirelessly.

[0009] Furthermore, a plurality of slide grooves are provided inside the main body, and sliders are fixed at the outer edges of the top plate at positions corresponding to the slide grooves.

[0010] Furthermore, the chute and the slider are both T-shaped.

[0011] Furthermore, the wireless force sensor uses Norilong's wireless force sensor + Bluetooth module.

[0012] The present invention also provides a method for using the above intelligent cement pole reinforcement and slurry retaining device, comprising the following steps:

[0013] (1) Connect the device to the baffle of the pole, insert the pier heads of the steel bars into the sealing sleeves one by one, fix the flange and baffle with bolts, and turn on the power;

[0014] (2) Control the wireless force sensor to zero on the touch screen, that is, enter the normal working state, and the device is installed;

[0015] (3) Setting an alarm threshold. If the data collected by the wireless force sensor exceeds the threshold, the alarm will sound.

[0016] (4) After the centrifugation process is completed, remove the device.

[0017] The present invention is beneficial in that:

[0018] (1) The sealing sleeve can effectively reduce or prevent the outflow of slurry, thus preventing the concrete in the mold from losing too much water under high-speed centrifugation, resulting in inconsistent water-cement ratio with the design and reduced strength;

[0019] (2) The top plate can prevent the steel bars from being ejected directly, and prevent the steel bars from being ejected during pumping or high-speed centrifugation, causing personal injury and product rework. It plays a blocking role when the steel bars are ejected, improving safety. In addition, through real-time monitoring by wireless force sensors, an alarm can be triggered to notify the staff as soon as the steel bars are separated from the baffle and ejected. Based on the data feedback, the technicians can judge whether it is necessary to terminate production and other issues, making objective judgments and ensuring the yield rate;

[0020] (3) After the steel bars are ejected, the slurry enters the shell through the rectangular drainage groove and is collected, and then discharged from the drainage port in a directional manner to avoid personal injury and slurry splashing and polluting the environment.

DETAILED DESCRIPTION

[0028] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1-6 As shown:

[0030] A smart cement pole reinforcement and slurry retaining device comprises a main body 2, a top plate 3, a bottom plate 22 and a shell 4. The main body 2 is cylindrical and has a flange 21 installed at the front end; the bottom plate 22 is welded to the rear end of the main body 2, the top plate 3 is located inside the main body 2 and slides, and a plurality of sealing sleeves 31 are arranged in a circular array on the front end surface of the top plate 3; a wireless force sensor 5 is installed between the top plate 3 and the bottom plate 22, and the wireless force sensor 5 is fixed on the bottom plate 22; a plurality of rectangular drainage grooves 24 are provided at equal angles on the peripheral wall of the main body 2, and a water retaining plate 33 is fixed on the inner side of the top plate 3 at the positions corresponding to the rectangular drainage grooves 24; the shell 4 is concentrically installed on the outer periphery of the main body 2 through a sealing bearing 41, and the rear end of the shell 4 is closed, and a drain outlet 2 is provided at the bottom; a touch screen 51 and an alarm 52 are installed on the outer wall of the shell 4, and a battery compartment 53 is installed on the bottom side as a counterweight to power the touch screen 51 and the alarm 52; the wireless force sensor 5 is independently powered and transmits data with the touch screen 51 and the alarm 52 wirelessly.

[0031] As an optimized solution, a number of slide grooves 23 are opened inside the main body 2, and sliders 32 are fixed at the outer edge of the top plate 3 corresponding to the positions of the slide grooves 23. This can ensure that the top plate 3 slides stably in the main body 2. The slide grooves 23 and the sliders 32 can be processed into T shapes.

[0032] In this device, the wireless force sensor 5 needs to be powered by its own lithium battery and transmits data wirelessly to the touch screen 51 and the alarm 52. It can be assembled independently or modularized with existing equipment, such as the wireless force sensor 5 + Bluetooth module from Norilong. Product features:

[0033] (1) It can monitor the clamping force in real time and compare it with the preset value, trigger an alarm in time, and support connection with Bluetooth module (model 85876) to achieve wireless data transmission without wiring.

[0034] (2) Self-contained power supply: The Bluetooth module provides power to the force sensor, and the module can be replaced without reconfiguration.

[0035] (3) High protection level, resistant to industrial environment.

[0036] How to use and working principle of this device:

[0037] a. First, workers connect the device to the baffle 12 of the pole's steel cage 1. The steel bar piers 11 are inserted into the sealing sleeves 31 one by one. The flange 21 and baffle 12 are fixed with bolts (screw holes can be drilled in the baffle 12 or screws can be welded). Due to the elastic force of the push rod, the wireless force sensor 5 pushes the top plate 3 and the steel bar pier 11 into a clamped state. The sealing sleeve 31 supports the baffle 12 to form a seal. The wireless force sensor 5 uses an independent battery, and data communication with the touch screen 51 uses Bluetooth transmission.

[0038] b. Control the wireless force sensor 5 to return to zero on the touch screen 51, that is, enter the normal working state. At this time, the device has been installed.

[0039] c. During centrifugation, the main body 2 rotates along with the pole. However, since the touch screen 51, alarm 52, and battery compartment 53 are all on the housing 4, the housing 4 and the main body 2 are connected by a sealed bearing 41, and there is a counterweight for the battery compartment 53, the housing 4 does not rotate (gyroscope principle). Therefore, this design will not damage the battery, alarm 52, and other equipment under high-speed rotation.

[0040] d. During rotation, the sealing sleeve 31 prevents significant slurry flow from the gap between the baffle 12 and the rebar, ensuring minimal water loss, a negative impact on the designed water-cement ratio, and guaranteed strength. If rebar is ejected, the top plate 3 moves backward, and the wireless force sensor 5 collects data. If the threshold is exceeded, the alarm 52 sounds, notifying management. However, due to the top plate 3, the rebar is prevented from being ejected and causing damage.

[0041] e. At this time, since the steel bars are ejected, but the top plate 3 is limited and the movement position will not be too large, the technicians need to determine whether to terminate the production. If not, the centrifugal process production can continue. However, since the top plate 3 retreats, the pier heads 11 of other steel bars will detach from the sealing sleeve 31, causing the slurry to flow out. At this time, the rectangular drainage groove 24 on the main body 2 comes into play, and the slurry is thrown out from the rectangular drainage groove 24 on the peripheral wall of the main body 2 by centrifugal force and hits the outer shell 4, and is finally collected by the outer shell 4 and flows out from the drain port 2 to avoid slurry splashing. The water retaining plate 33 provided on the top plate 3 can always block the rear end opening of the rectangular drainage groove 24 as it slides, preventing the slurry from entering between the top plate 3 and the bottom plate 22 and damaging the wireless force sensor 5.

[0042] f. After the centrifugation process is completed, the device is removed. The above embodiments of the present invention are described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions, and variations of these embodiments may be made without departing from the principles and spirit of the present invention, and the same shall still fall within the scope of protection of the present invention.
