The specific operation is: 2 people on the pole are responsible for the installation of pulleys, wire ropes, etc., and the tractor-type winch truck needs to be fixed in place on the ground in advance. At least 5 people are required to operate when tightening the line, which involves certain safety risks and increases in labor and machinery costs.

[0003] During the wire laying process, the wire may be pulled back or slipped due to its own gravity, which affects the efficiency of the entire wire laying. Although there are devices on the market for clamping and positioning the wire, the corresponding structures are relatively complex. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent wire tightening device, aiming to solve the problem that the device for clamping and positioning the wire is relatively complicated.

[0006] A housing, wherein a wire is inserted into the housing;

[0007] Two pay-off wheels, the two pay-off wheels are mounted on the inner wall of the housing and are arranged opposite to each other, and the two pay-off wheels cooperate to pay off the wire;

[0008] Two wire-clamping wheels, both of which are mounted on the inner wall of the housing and located on one side of the two wire-releasing wheels;

[0010] The two wire clamping wheels are used to limit the wire through the brake sleeve.

[0011] In a possible implementation, both of the two wire-gripping wheels are provided with a clamping groove that is clamped with the brake sleeve, and the two clamping grooves are respectively arranged on one side of the two wire-gripping wheels that are close to each other.

[0012] In a possible implementation, both of the two wire clamping wheels are elliptical, both of the two wire clamping wheels are rotatably mounted on the housing, and the minimum distance between the two wire clamping wheels is smaller than the outer diameter of the brake sleeve.

[0013] In a possible implementation, the angle between the long axes of the two wire clamping wheels is an acute angle.

[0014] In a possible implementation, the two wire clamping wheels are symmetrically distributed.

[0015] In a possible implementation, a limit block engaged with the clamping groove is provided on the outer wall of the brake sleeve; the limit block is used to make the wire clamping wheel swing within a certain range through engagement transmission with the clamping groove.

[0016] In a possible implementation, both ends of the brake sleeve are provided with cut-off blocks, the two cut-off blocks are distributed on both sides of the two wire clamping wheels, and the thickness of the cut-off blocks is greater than the maximum distance between the two wire clamping wheels.

[0017] In a possible implementation, the brake sleeve includes two oppositely arranged brake petals, and the two brake petals are used to be sleeved on the wire through bolts; the two limit blocks are integrally formed on the outer wall of the brake petal, and the two stop blocks are welded and fixed at both ends of the brake petal.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Please also read Figure 1 to Figure 2 , the intelligent wire tensioning device provided by the present invention is now described. The intelligent wire tensioning device comprises: a housing 1, two wire-paying wheels 2, two wire-clamping wheels 3 and a brake sleeve 5. A wire is passed through the housing 1. The two wire-paying wheels 2 are mounted on the inner wall of the housing 1 and arranged opposite to each other, and the two wire-paying wheels 2 are used to pay out the wire. The two wire-clamping wheels 3 are both mounted on the inner wall of the housing 1 and are located on one side of the two wire-paying wheels 2. The brake sleeve 5 is used to be sleeved and fixed on the wire, and the brake sleeve 5 is arranged between the two wire-clamping wheels 3, and is respectively engaged with the two wire-clamping wheels 3. The two wire-clamping wheels 3 are used to limit the wire through the brake sleeve 5.

[0030] The beneficial effect of the intelligent wire tightening device provided by the present invention is that compared with the prior art, the two wire pay-off wheels 2 and the two wire clamping wheels 3 in the intelligent wire tightening device of the present invention are both installed on the housing 1, the two wire pay-off wheels 2 are arranged opposite to each other, the two wire clamping wheels 3 are arranged opposite to each other, and the two wire clamping wheels 3 are located on one side of the two wire pay-off wheels 2. A brake sleeve 5 is mounted on the wire, and the brake sleeve 5 is arranged between the two wire clamping wheels 3 and is clamped and matched with the two wire clamping wheels 3 respectively.

[0031] In actual application, the wire is passed between the two pay-off wheels 2 and between the two clamping wheels 3. The two pay-off wheels 2 cooperate to pay off the wire, and the two clamping wheels 3 are both clamped and matched with the brake sleeve 5.

[0032] After the wire is paid out, the brake sleeve 5 is put on the wire and is clamped between the two wire clamping wheels 3. When the wire has a tendency to move, the wire exerts a force on the brake sleeve 5, and the brake sleeve 5 acts on the two wire clamping wheels 3. Since the two wire clamping wheels 3 and the brake sleeve 5 are clamped, the brake sleeve 5 can be stabilized in a specific position through the two wire clamping wheels 3. After the position of the brake sleeve 5 is stabilized, the position of the wire is also determined, and the wire is finally prevented from loosening.

[0033] In the present application, two pay-off wheels 2 pay out the wire, and two clamping wheels 3 limit the position of the wire through a brake sleeve 5. The overall structure of the device is relatively simple, which is convenient for installation and improves work efficiency.

[0034] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 2 The two wire clamping wheels 3 are both provided with clamping grooves for clamping with the brake sleeve 5, and the two clamping grooves are respectively arranged on the sides of the two wire clamping wheels 3 close to each other.

[0035] In order to enable the brake sleeve 5 to be effectively engaged with the wire clamping wheel 3, a clamping groove is opened on the side close to the two wire clamping wheels 3, and the two clamping grooves on the two wire clamping wheels 3 are arranged opposite to each other, that is, the brake sleeve 5 will be engaged with the clamping grooves on the two wire clamping wheels 3 at the same time.

[0036] When the wire tends to loosen or move, the wire will exert a force on the brake sleeve 5. The brake sleeve 5 can simultaneously exert a force on the two wire-gripping wheels 3 by engaging with the two clamping grooves. With the help of the position and structure of the two wire-gripping wheels 3, the brake sleeve 5 has a certain braking effect.

[0037] As a basic industry of the national economy, the development of my country's power industry has also entered a new growth period. As of 2013, my country's total power generation reached 520.7 billion kWh, a year-on-year increase of 9.2%, ranking first in the world. The per capita electricity consumption was 3,596 kWh, an increase of 8.7% over the previous year, which has exceeded the world average. From a global perspective, since 1990, the per capita electricity consumption in developed countries has grown slowly, gradually approaching or tending to saturation. Especially after 2000, the level of economic development has stabilized, the growth rate of electricity consumption has slowed down, and even some developed countries have seen a decline in electricity consumption.

[0038] From this we can see that a country's electricity demand will not always maintain a growth trend. The electricity demand may reach saturation or even decrease. Therefore, the power grid as an energy carrier will not always maintain a high-speed development state. As social and economic development tends to stabilize and the basic infrastructure of the power grid is basically improved, the development of the power grid will gradually tend to saturation.

[0039] Although the development of power grids in various countries is affected by their own unique economic, social and environmental factors, the development of power grids in various countries still follows the basic laws of power grid development. Therefore, it is necessary to study the development history of power grids in various countries, sort out and extract the general laws of power grid development, clarify the basic development period that power grid development must go through and its characteristics within this development period, so as to provide reference for the development of my country's power grid. This will help to improve the understanding of the development laws and future development trends of my country's power grid, and help relevant departments to carry out power grid planning and investment work according to the development period of their own power grids, so that the relevant power grid planning and investment will be more forward-looking and economical, thereby ensuring that the power grid has higher security and economy, and can better serve the development of social economy.

[0040] The construction of power grid projects has entered a stage of comprehensive and rapid development. Transmission line projects have a wide regional span, and a large number of them cross important facilities such as transmission lines, electrified railways, and high-speed railways. The contradiction between line crossing construction and the operation of power grids and railway networks has become increasingly prominent. In particular, the requirements for the safe operation of power grids and railway networks are becoming increasingly stringent, which puts higher requirements on the operation methods, operation time limits, and construction safety of line crossing construction.

[0041] At present, the traditional construction method is still used for the construction of transmission line crossings. The on-site construction is carried out according to the design data for layout and fitting. The common wiring method of transmission line projects currently requires multiple processes such as crossing construction, laying out guide (traction) ropes, laying out ground wires, sag observation, drawing and printing, anchoring lines, crimping and hanging lines, and accessory installation to meet the relevant requirements of the design and specifications. The construction process is long, the procedures are complicated, and there are many uncontrollable factors, which leads to low construction efficiency, many safety risks, and great difficulty in construction quality control.

[0042] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 1 and Figure 2 The two wire clamping wheels 3 are both elliptical in shape, and are rotatably mounted on the housing 1 . The minimum distance between the two wire clamping wheels 3 is smaller than the outer diameter of the brake sleeve 5 .

[0043] The distance between the axes of the two wire clamping wheels 3 is fixed. Both wire clamping wheels 3 are elliptical. Since the ellipse has a major axis and a minor axis, the distance between the outer surfaces of the two wire clamping wheels 3 will change in real time. If the minimum distance between the two wire clamping wheels 3 is smaller than the diameter of the brake sleeve 5, the two wire clamping wheels 3 will gradually squeeze the brake sleeve 5 on the wire during rotation. As the wire clamping wheels 3 squeeze the brake sleeve 5, the wire will be confined to a specific position through the brake sleeve 5.

[0044] In practical application, the relative positions and spatial angles of the two clamping wheels 3 need to be reasonably arranged. The wires in the power grid may have a tendency to move in two opposite directions under the influence of the external environment, so the two clamping wheels 3 are needed to limit the brake sleeve 5 in two directions.

[0045] Here, the elliptical clamping wheel 3 can rotate in two directions and form a minimum spacing, thereby limiting the brake sleeve 5 in two directions.

[0046] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 1 and Figure 2 , the angle between the long axes of the two clamping wheels 3 is an acute angle.

[0047] In order to enable the wire clamping wheel 3 to swing a certain angle in both directions, when the wire is in a horizontal state, the angle between the long axis direction of the wire clamping wheel 3 and the wire is an acute angle, and the angle between the two long axis directions of the two wire clamping wheels 3 is also an acute angle.

[0048] Through this arrangement, the wire clamping wheel 3 can swing a certain angle in both directions, so that the distance between the two directions can be gradually reduced, and finally the two extreme positions of the brake sleeve 5 and the wire can be limited.

[0049] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 1 and Figure 2 , the two wire clamping wheels 3 are symmetrically distributed.

[0050] In order to facilitate installation and assembly, the two wire-gripping wheels 3 need to be symmetrically distributed on both sides of the wire. After the brake sleeve 5 is put on the wire, the long axes of the two wire-gripping wheels 3 are parallel to each other and to the length direction of the wire, ensuring that the amplitude of movement of the wire-gripping wheels 3 in two directions is the same.

[0051] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 2 A limit block 7 engaged with the slot is provided on the outer wall of the brake sleeve 5; the limit block 7 is used to make the wire clamping wheel 3 swing within a certain range through the engagement transmission with the slot.

[0052] For a more detailed description, a limit block 7 is provided on the brake sleeve 5, and the limit block 7 is integrally formed on the brake sleeve 5. The two limit blocks 7 on the brake sleeve 5 are respectively engaged with the two clamping grooves on the two clamping wheels 3.

[0053] When the wire drives the brake sleeve 5 to move, the limit block 7 on the brake sleeve 5 will always be in meshing with the clamping groove. Since it is always in meshing state, the limit block 7 can drive the clamping wheel 3 to swing within a certain range. The clamping wheel 3 is elliptical, which causes the distance between the two clamping wheels 3 to change under the drive of the brake sleeve 5.

[0054] When the limit block 7 drives the wire clamping wheel 3 to move to the extreme position, the two wire clamping wheels 3 will squeeze the brake sleeve 5. As the movement trend of the brake sleeve 5 becomes stronger, the force of the wire clamping wheel 3 on the brake sleeve 5 will become greater. At this time, the brake sleeve 5 will squeeze the wire, thereby increasing the maximum static friction between the brake sleeve 5 and the wire, and finally preventing the wire from slipping.

[0055] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 2 Both ends of the brake sleeve 5 are provided with cut-off blocks 6 , and the two cut-off blocks 6 are distributed on both sides of the two wire clamping wheels 3 , and the thickness of the cut-off blocks 6 is greater than the maximum spacing between the two wire clamping wheels 3 .

[0056] The brake sleeve 5 is directly sleeved on the wire. By tightening the bolts and other components on the brake sleeve 5, the squeezing force of the brake sleeve 5 on the wire can be effectively guaranteed, that is, a series of problems such as looseness between the brake sleeve 5 and the wire can be avoided.

[0057] First, the structure of the wire clamping wheel 3 itself is determined, and the distance between the axes of the two wire clamping wheels 3 is fixed. In order to further limit the limit position of the wire, a cut-off block 6 is provided at both ends of the rotating sleeve, and the thickness of the cut-off block 6 is greater than the maximum distance between the two wire clamping wheels 3. Even if the limit block 7 slips off the clamping slot, the cut-off block 6 cannot pass through the two wire clamping wheels 3, which prevents the wire from slipping off to a certain extent.

[0058] There are two cut-off blocks 6 , and the two cut-off blocks 6 can define the extreme positions of the conductor in two directions.

[0059] In some embodiments of the intelligent tensioning device provided in the present application, the brake sleeve 5 includes two oppositely arranged brake petals, which are used to be sleeved on the wire through bolts; the two limit blocks 7 are integrally formed on the outer wall of the brake petal, and the two stop blocks 6 are welded and fixed at both ends of the brake petal.

[0060] The brake sleeve 5 itself has a certain length, and includes two brake petals, one end of which is hinged to each other, and the other end is fixed by bolts or other components. When the two brake sleeves 5 are bolted onto the wire, the wire can be tightly held. At this time, there is a large force between the brake sleeve 5 and the wire, thereby avoiding the occurrence of problems such as misalignment or slippage between the brake sleeve 5 and the wire.

[0061] In actual application, the wire is firstly released by two pay-off wheels 2. After the pay-off wheels 2 release the wire to the specified position, the brake sleeve 5 is mounted on the wire, and the wire is now located between the two clamping wheels 3. For the convenience of operation, the wire can be lifted from between the two clamping wheels 3, and after the brake sleeve 5 is installed, the brake sleeve 5 is clamped and matched with the two clamping wheels 3 respectively.

[0062] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 2 One of the pay-off wheels 2 is connected to a motor, and a sensor 8 is installed on the limit block 7. The sensor 8 is used to fit the tension on the wire; when the value measured by the sensor 8 exceeds the threshold, the motor is used to provide a force in the opposite direction to the wire through the pay-off wheel 2.

[0063] Pressure sensor 8 is the most commonly used sensor 8 in industrial practice. Traditional pressure sensor 8 is mainly a mechanical structure device, and the deformation of the elastic element indicates the pressure. However, this structure is large in size and heavy in weight, and cannot provide electrical output, so it is most commonly used in the industrial field.

[0064] With the development of semiconductor technology, semiconductor pressure sensors 8 have also emerged, which are characterized by small size, light weight, high accuracy and good temperature characteristics. In particular, with the development of MEMS technology, semiconductor sensors 8 are developing towards miniaturization, and have low power consumption and high reliability.

[0065] A micro tension and pressure sensor 8 (sometimes called a strain sensor 8) is a sensor 8 whose resistance changes with the applied force; it converts physical quantities such as force, pressure, tension, weight, etc. into changes in resistance, thereby measuring these physical quantities. When an external force acts on a fixed object, stress and strain are generated. The reaction force generated inside the object is stress, and the displacement and deformation generated are strain.

[0066] In order to effectively evaluate the stress on the wire, the state of the wire at this time can be calculated. Therefore, a sensor 8 is installed on the limit block 7. In actual application, the sensor 8 on the limit block 7 is connected to the host computer, and the host computer is electrically connected to the motor. The host computer can determine the data collected by the sensor 8, and can roughly calculate the stress state on the wire at this time based on experience. When the value collected by the sensor 8 is greater than the preset standard, it is necessary to conduct a field inspection on site. At the same time, the host computer controls the motor to move the motor in the opposite direction. The movement of the motor in the opposite direction will have an opposite force on the wire, which can prevent the wire from further loosening.

[0067] In some embodiments of the intelligent wire tightening device provided in this application, please refer to Figure 2 , both pay-off wheels 2 are provided with annular grooves, in which anti-skid sleeves 4 are sleeved, and the anti-skid sleeves 4 are used to abut against the wire and drive the wire to move.

[0068] Both pay-off wheels 2 need to rely on friction to pay off the wire. In order to ensure that there is sufficient friction between the wire and the pay-off wheel 2, annular grooves are provided along the circumference of the pay-off wheel 2. An anti-slip sleeve 4 is installed in the annular groove. The anti-slip sleeve 4 is made of flexible plastic material and is used to increase the friction between the wire and the pay-off wheel 2.

[0069] In order to make the pay-off wheel 2 rotate stably, the pay-off wheel 2 is connected to a motor for driving one or two pay-off wheels 2. The motor is connected to a control switch for making the pay-off wheel 2 rotate forward or reversely.

[0070] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. Its working principle is to convert the pressure of compressed air into mechanical energy through pneumatic transmission, so that the mechanism can perform linear reciprocating motion, or swing and rotation motion. The cylinder can be divided into four types: single-acting cylinder, double-acting cylinder, diaphragm cylinder, and impact cylinder.

[0071] A cylinder is installed on the driving wheel with a motor, and the cylinder can drive the driving wheel to reciprocate in one direction, that is, the distance between the two pay-off wheels 2 can be increased or decreased under the action of the cylinder. When it is necessary to pay off the wire, the distance between the two pay-off wheels 2 is shortened under the action of the cylinder so that both pay-off wheels 2 are effectively against the wire. After the pay-off is completed, the cylinder is used to move the corresponding pay-off wheel 2 away from the wire, and at this time, the stress on the wire can be effectively determined by the sensor 8 on the limit block 7.

[0072] When the value detected by the sensor 8 on the limit block 7 is too large, that is, the wire tends to slip, the cylinder makes the pay-off wheel 2 press against the wire as much as possible, and then the motor rotates in the opposite direction to make the wire acted on in the opposite direction, and the pay-off wheel 2 keeps the wire pulled in the opposite direction until the fault is eliminated.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
