Description

Technical Field

[0001] The invention relates to the technical field of measuring instruments, in particular to a double meter-counting device for galvanized steel stranded wires. Background Art

[0002] The meter device is an instrument used to measure the length of the cable. It usually uses a roller or sensor to detect the movement of the cable to calculate the length. Specifically, the running cable directly contacts the roller, and the friction between the cable and the roller is used to drive the roller to rotate. The sensor detects the number of rotations of the roller to obtain the cable length data.

[0003] For the metering process of galvanized steel strands, since the running steel strands will have a certain degree of shaking, and the steel strands may not contact the rollers, the metered length will be less than the actual length of the steel strands, resulting in monitoring errors. The surface of the galvanized steel strands is coated with a layer of zinc. During the contact and friction between the steel strands and the rollers, the steel strands will be worn and the zinc powder on the surface will fall off. If the hard particles in the zinc powder adhere to the roller surface, it will accelerate its wear. Moreover, if the zinc powder accumulates on the roller surface, it may reduce the friction between the steel strands and the rollers, causing slippage, that is, the rollers and the steel strands slide relative to each other, resulting in reduced metering accuracy. Summary of the invention

[0004] In order to solve the problem that conventional metering devices are prone to slipping, which leads to reduced accuracy of metering data, the present invention provides a double metering device for galvanized steel strands. The steel strands are elastically clamped by two metering wheels close to each other, which can be suitable for measuring steel strands with different wire diameters and specifications. The zinc powder that has fallen off can be cleaned and collected, and the elastic clamping can be used to prevent slipping. The dual monitoring means of mechanical metering and sensor metering are combined to ensure the accuracy of metering data.

The tension spring group forces the two meter-counting wheels to approach each other.

[0011] Furthermore, the meter wheel has a diameter greater than the width of the adsorption frame, and limited segments are arranged at the upper and lower ends of the meter wheel. The diameter of the limited segments is greater than the diameter of the meter wheel, which is convenient for limiting the up and down shaking of the steel strand. The meter wheel and the limited segments are both wheel bodies made of metal; The adsorption frame includes a frame body, a soft-bristle brush frame and an adsorption cover.

Even if the running steel strand shakes slightly, the meter wheel can follow and slide slightly, thereby effectively adapting to the shaking of the steel strand. The steel strand can still stably drive the meter wheel to rotate, thereby improving the metering accuracy.

[0018] The adsorption frame of the present invention comprises a frame body, a soft brush frame and an adsorption cover, and the adsorption frame is connected to an exhaust fan. The soft brush frame contacts the surface of the meter wheel, and can clean the zinc powder on the surface of the meter wheel. The zinc powder is collected and processed in time by the adsorption cover, thereby avoiding the slipping phenomenon caused by the presence of zinc powder and ensuring sufficient friction between the steel strand and the meter wheel.

DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings: like Figure 1 to Figure 12 As shown, the double metering device for galvanized steel strands comprises a lifting mechanism 1, a metering platform 4, a guiding unit 5 and a metering unit 6. Figure 1~Figure 4The lifting mechanism 1 is arranged vertically, and has a height adjustment function. A metering platform 4 is arranged above the lifting mechanism 1, and the metering platform 4 is arranged horizontally. The lifting mechanism 1 can drive the metering platform 4 to adjust its height.

[0033] In this embodiment, the lifting mechanism 1 is manually operated to achieve height adjustment. The lifting mechanism 1 includes a base plate 101, a telescopic rod 102 and a reinforcing plate 104. Figure 5 As shown. The base plate 101 is a rectangular steel plate, and the base plate 101 is fixed to the ground with expansion bolts. A telescopic rod 102 is arranged in the center of the base plate 101, and the telescopic rod 102 is arranged vertically. The telescopic rod 102 has a telescopic function, thereby enabling the lifting mechanism 1 to be height-adjustable. A triangular reinforcing plate 104 is arranged between the bottom of the telescopic rod 102 and the base plate 101. The number of reinforcing plates 104 is a plurality of evenly distributed annularly, and the reliability of the installation of the telescopic rod 102 is achieved through the reinforcing plate 104.

[0034] The telescopic rod 102 includes a lower tube 2, an upper column 3 and a hand wheel 103. The lower tube 2 is a round tube structure, and the lower tube 2 is fixedly connected to the base plate 101. A reinforcing plate 104 is arranged between the lower tube 2 and the base plate 101 to improve the reliability of the connection between the lower tube 2 and the base plate 101. The upper column 3 is inserted into the lower tube 2, and the upper column 3 slides up and down in the lower tube 2. The upper column 3 is a screw structure, and the upper end of the upper column 3 extends out of the lower tube 2 and is connected to the meter-counting platform 4, thereby supporting the meter-counting platform 4.

[0035] On the basis that the lower cylinder 2 is fixed and the upper column 3 can slide up and down, in order to realize the sliding of the upper column 3, a hand wheel 103 is rotatably connected to the upper end of the lower cylinder 2. The hand wheel 103 is a circular ring body, and the hand wheel 103 is provided with three joysticks arranged circumferentially, and the joysticks are arranged radially along the hand wheel 103. When the hand wheel 103 is installed, an outer flange 201 is arranged on the upper end of the lower cylinder 2, and the lower end of the hand wheel 103 is against the outer flange 201, and a plane bearing 10 is arranged between them, which limits the downward movement of the hand wheel 103; at the same time, a plurality of vertical bolts 11 are arranged circumferentially on the edge of the lower end of the hand wheel 103, and the heads of the vertical bolts 11 are stuck on the edge of the outer flange 201, which limits the upward movement of the hand wheel 103, so that the axial movement of the hand wheel 103 can be avoided, and the hand wheel 103 is prevented from being separated from the lower cylinder 2, and the circumferential rotation of the hand wheel 103 is not interfered.

[0036] The hand wheel 103 after installation is sleeved on the outer side of the upper column 3 and is threadedly connected to the upper column 3. In order to drive the upper column 3 to move up and down by rotating the hand wheel 103, limit bolts 12 are also arranged on both sides of the lower cylinder 2, and limit slots 13 are provided on both sides of the upper column 3. The limit bolts 12 and the limit slots 13 correspond to each other one by one. The corresponding limit bolts 12 pass through the lower cylinder 2 and are inserted into the limit slots 13, thereby preventing the upper column 3 from rotating. Then, the hand wheel 103 is manually operated to rotate, so that the lifting and lowering of the upper column 3 can be controlled, thereby driving the metering platform 4 to be lifted and lowered.

[0037] The meter-counting platform 4 is a rectangular plate made of steel plate, and lifting holes 14 are provided at the four corners of the meter-counting platform 4. The lifting holes 14 are threaded holes, and the lifting holes 14 are used to connect eyebolts to facilitate the lifting and movement of the meter-counting platform 4. A bottom ring 15 is provided at the center of the lower part of the meter-counting platform 4, and the bottom ring 15 is sleeved on the top of the upper column 3, and an axle pin is passed between the bottom ring 15 and the upper column 3, so as to realize the secure installation of the meter-counting platform 4 and the upper column 3 and prevent the meter-counting platform 4 from falling off.

[0038] Guide units 5 are arranged at intervals on both sides of the metering platform 4, a metering unit 6 is arranged in the middle of the metering platform 4, and the steel strand is passed between the guide unit 5 and the metering unit 6. Under the guidance of the guide unit 5, it can be ensured that the running steel strand passes through the metering unit 6 accurately, that is, the guide unit 5 plays a guiding role, and the steel strand can be smoothly introduced into the metering unit 6 and then led out to the next process.

[0039] The guide units 5 on both sides are arranged symmetrically, and the guide units 5 include vertical guide rollers 51 and horizontal guide rollers 52. Figure 6 As shown. There are two vertical guide rollers 51 arranged at intervals. The vertical guide rollers 51 are arranged vertically. The vertical guide rollers 51 are far away from the metering unit 6. The vertical guide rollers 51 include a roller shaft and a roller body. The roller shaft is inserted into the roller body, and the roller shaft and the roller body are rotatably connected. When the vertical guide rollers 51 are installed, a long hole 16 is opened on the metering platform 4. The vertical guide rollers 51 are arranged on both sides of the long hole 16. The roller shafts of the vertical guide rollers 51 pass downward through the long hole 16 and are connected with nuts. Tightening the nuts can fix the vertical guide rollers 51. After loosening the nuts, the position of the vertical guide rollers 51 can be adjusted in the long hole 16, and then the distance between the two vertical guide rollers 51 can be adjusted. The steel strand is wound between the two vertical guide rollers 51, and the vertical guide rollers 51 can limit the left and right swing of the steel strand.

[0040] The transverse guide roller 52 has the same structure as the vertical guide roller 51. The transverse guide roller 52 is arranged horizontally and is close to the metering unit 6. The length of the transverse guide roller 52 is greater than the center distance between the two vertical guide rollers 51. When the transverse guide roller 52 is installed, two mounting brackets 17 are also provided on the metering platform 4. The mounting brackets 17 are bent into an L shape. Each mounting bracket 17 is provided with a height adjustment hole 18. The height adjustment hole 18 is a vertically arranged strip hole. The two ends of the roller shaft of the transverse guide roller 52 extend out of the two height adjustment holes 18 and are connected with nuts. The position of the transverse guide roller 52 can be fixed by tightening the nut. After loosening the nut, the transverse guide roller 52 can move up and down in the height adjustment hole 18 to adjust the height. The steel strand is wound around the top of the transverse guide roller 52, and the transverse guide roller 52 can limit the downward movement of the steel strand.

[0041] The meter unit 6 can measure the length of the steel strand in operation. The meter unit 6 includes a slide rail 7, an adsorption frame 8, a meter wheel 9 and a counter. Figure 7 and Figure 8As shown. The slide rail 7 is fixedly connected to the metering platform 4, and the arrangement direction of the slide rail 7 is perpendicular to the running direction of the steel strand. The two ends of the slide rail 7 are elastically slidably connected with the adsorption frame 8, that is, the adsorption frame 8 slides on the slide rail 7, and the adsorption frame 8 is subjected to elastic force when sliding, so that the two adsorption frames 8 tend to be close to each other in the initial state.

[0042] When the adsorption frame 8 is installed, a slider 19 is provided at the bottom of the adsorption frame 8, and the adsorption frame 8 is slidably connected to the slide rail 7 through the slider 19, so that the distance between the two adsorption frames 8 is adjustable. With the cooperation of the slider 19 and the slide rail 7, the adsorption frame 8 can be lifted upward to keep a certain distance between the adsorption frame 8 and the meter-counting platform 4. A tension spring group 21 is also provided between each adsorption frame 8 and the meter-counting platform 4, and the action of the tension spring group 21 causes the two adsorption frames 8 to approach each other. In the initial state, the distance between the two adsorption frames 8 is the smallest.

[0043] In this embodiment, two tension spring groups 21 are arranged in parallel on both sides of the slide rail 7. The tension spring group 21 includes a tension spring body 211, a mounting bolt 1 212, and a mounting bolt 2 213 arranged in a straight line. The mounting bolt 1 212 is connected to the bottom of the adsorption frame 8 upward, and the mounting bolt 2 213 is connected to the metering platform 4 downward. There is a gap between the mounting bolt 1 212 and the mounting bolt 2 213. The two ends of the tension spring body 211 are hooked with the mounting bolt 1 212 and the mounting bolt 2 213 respectively. Under the action of the tension spring body 211, the two adsorption frames 8 move relative to each other.

[0044] The cross section of the adsorption frame 8 is in the shape of a Chinese character “U”. A meter wheel 9 is rotatably arranged in each adsorption frame 8. The diameter of the meter wheel 9 is larger than the width of the adsorption frame 8. The line connecting the two meter wheels 9 is perpendicular to the line connecting the two guide units 5. The line connecting the two guide units 5 is consistent with the running direction of the steel strand. As the two adsorption frames 8 tend to approach each other, the two meter wheels 9 also approach each other. Under the action of the tension spring group 21, an elastic clamping force is generated between the two meter wheels 9. The two meter wheels 9 elastically clamp the steel strand.

[0045] In order to prevent the steel strand from excessively deviating along the axial direction of the meter wheel 9, the meter wheel 9 is provided with limited segments 91 at the upper and lower ends. The diameter of the limited segments 91 is larger than the diameter of the meter wheel 9. The meter wheel 9 and the limited segments 91 are both wheel bodies made of metal. The steel strand contacts the wheel surface of the meter wheel 9 between the two limited segments 91, and the limited segments 91 prevent the steel strand from moving up and down out of the meter wheel 9.

[0046] Since the two meter wheels 9 cooperate, the steel strand can be elastically clamped, and the running steel strand can drive the meter wheel 9 to rotate, and the length of the steel strand can be determined by monitoring the rotation of the meter wheel 9. Specifically, a counter is provided on any adsorption frame 8, and the counter is connected to the meter wheel 9 in the adsorption frame 8 to monitor the number of rotations of the meter wheel 9. The counter is a mechanical counter 20, an electronic counter, or a combination of the two, that is, the mechanical counter 20 or the electronic counter can be used alone for monitoring, or the mechanical counter 20 and the electronic counter can be used simultaneously for monitoring.

[0047] In this embodiment, the counter is a combination of a mechanical counter 20 and an electronic counter, that is, the mechanical counter 20 and the electronic counter are used simultaneously to detect the number of rotations of the meter wheel 9. Fig. 9 As shown, when the counter is installed, a gear set 22 is provided between the input shaft of the mechanical counter 20 and the meter wheel 9. The gear set 22 is two meshing bevel gears. A protective shell 23 is also provided on the adsorption frame 8. The gear set 22 is arranged in the protective shell 23 to protect the gear set 22.

[0048] The electronic counter includes a sensor 24, a magnet 25 and an electronic counter body. The sensor 24 is vertically arranged on the adsorption frame 8, and the sensor 24 is a Hall sensor 24. The magnet 25 is arranged on the upper end surface of the meter wheel 9. The magnet 25 and the sensor 24 are kept at a certain interval. The magnet 25 and the sensor 24 cooperate to detect the number of rotations of the meter wheel 9. The sensor 24 is connected to the electronic counter body through a data line, and the electronic counter body is not shown in the figure.

[0049] The principle of the present invention is as follows: according to the height of the steel strand, the height of the lifting mechanism 1 is adjusted, and the lifting mechanism 1 is used to drive the meter unit 6 to move up and down, so that the steel strand is placed within the operating range of the meter wheel 9. The meter wheels 9 are manually moved to both sides to move away from each other, and then the steel strand is placed between the two meter wheels 9. After the meter wheels 9 are released, the meter wheels 9 are moved closer to each other under the action of the two tension spring groups 21, and the meter wheels 9 cooperate to clamp the steel strand.

[0050] During the operation of the steel strand, no matter which direction the steel strand deviates toward, the steel strand can be closely contacted with the meter wheel 9 under the action of the tension spring group 21, so that the steel strand can drive the meter wheel 9 to rotate reliably, thereby preventing the steel strand and the meter wheel 9 from slipping. At the same time, during the rotation of the meter wheel 9, the mechanical counter 20 directly monitors the number of rotations of the meter wheel 9, and the electronic counter can also monitor the number of rotations of the meter wheel 9, and then the length of the steel strand can be obtained by calculation.

[0051] Since the galvanized steel strand contacts and rubs against the length measuring wheel 9, zinc powder will fall off. To prevent zinc powder from remaining on the surface of the length measuring wheel 9, suction fans are respectively connected to both sides of each adsorption frame 8 through air pipes, so that the fallen zinc powder can be sucked away in time. The air pipes and the suction fans are not shown in the figure. Specifically, the adsorption frame 8 includes a frame body 81, a soft brush frame 82, and an adsorption cover 83. The cross-section of the frame body 81 is in the shape of a "hui" character. The frame body 81 is rotatably connected to the length measuring wheel 9. A slider 19 is arranged at the bottom of the frame body 81, as Figure 10~Figure 12 shown.

[0052] Soft brush frames 82 are arranged around the inner periphery of the frame body 81. Two soft brush frames 82 are arranged on one frame body 81. Specifically, soft brush frames 82 are arranged at both ends of the opening of the frame body 81. The cross-section of the soft brush frame 82 is in the shape of a "hui" character, that is, the soft brush frame 82 is a "hui" character structure formed by connecting four soft brush plates. The soft brush frame 82 is connected to the inner walls around the frame body 81 by screws, and the soft brush frame 82 contacts the surface of the length measuring wheel 9. In this way, each soft brush frame 82 contacts the wheel surface and the upper and lower end surfaces of the length measuring wheel 9 through soft brushes. During the rotation of the length measuring wheel 9, the soft brush frame 82 can remove zinc powder from the surface of the length measuring wheel 9 in multiple directions.

[0053] In order to collect and process the removed zinc powder in time, adsorption covers 83 are respectively arranged on the left and right sides of the frame body 81. The connection line of the two adsorption covers 83 is perpendicular to the connection line of the two soft brush frames 82, and the adsorption covers 83 are arranged between the two soft brush frames 82. One end of the adsorption cover 83 expands and faces the length measuring wheel 9, and the other end of the adsorption cover 83 shrinks and is connected to the suction fan through an air pipe.

[0054] Specifically, the adsorption cover 83 includes a rectangular section 26, a conical section 27, a circular pipe section 28, and a filter cartridge 29. The rectangular section 26, the conical section 27, and the circular pipe section 28 are connected in sequence and integrally formed. The size of the rectangular section 26 is larger than that of the circular pipe section 28, and the transition between the rectangular section 26 and the circular pipe section 28 is through the conical section 27. An opening is made on the frame body 81, and the rectangular section 26 is embedded into the frame body 81 through this opening position. The rectangular section 26 is close to the wheel surface of the length measuring wheel 9, and the height of the rectangular section 26 is greater than the height of the length measuring wheel 9.

[0055] An installation ring section 30 is also integrally formed on the conical section 27. The installation ring section 30 is arranged outside the circular pipe section 28, and a filter cartridge 29 is threadedly connected to the installation ring section 30. The filter cartridge 29 includes a cylinder body 291 with openings at both ends and a filter element 292 arranged inside the cylinder body 291. One end of the cylinder body 291 has a large opening and the other end has a small opening. The large-diameter end of the cylinder body 291 is threadedly connected to the installation ring section 30, the circular pipe section 28 is inserted into the cylinder body 291, and the small-diameter end of the cylinder body 291 is connected to the air pipe.

[0056] The filter element 292 is a hollow cylinder with a "U"-shaped cross-section. One end of the filter element 292 with an opening faces the circular tube section 28, and the diameter of the filter cartridge 29 is larger than that of the circular tube section 28. The filter element 292 has a two-layer structure and includes a filter cloth layer 2921 and a filter mesh layer 2922. The filter mesh layer 2922 is used to support the filter cloth layer 2921 to ensure the stable shape of the filter cloth layer 2921. The filter mesh layer 2922 cooperates with the cylinder body 291 to clamp the filter cloth layer 2921.

[0057] The entire process of zinc powder cleaning is as follows: The soft brush frame 82 sweeps the zinc powder on the surface of the length measuring wheel 9. After the exhaust fan operates, the zinc powder within the range of the adsorption hood 83 is extracted through the air pipe, and thus the zinc powder swept by the soft brush frame 82 can be adsorbed into the filter cartridge 29. The zinc powder is intercepted and collected by the filter element 292, thereby ensuring that there is no zinc powder adhering to the surface of the length measuring wheel 9. After the length measuring wheel 9 has rotated for a period of time, the filter cartridge 29 can be removed and the filter element 292 can be taken out for zinc powder cleaning. By cleaning the zinc powder, the accumulation of zinc powder on the surface of the length measuring wheel 9 is avoided, mechanical friction is reduced, the smooth rotation of the length measuring wheel 9 is ensured, and at the same time, the situation where the steel wire strand slips with the length measuring wheel 9 due to the presence of zinc powder is avoided, and the interference of zinc powder with the monitoring operation of the sensor 24 and the magnet 25 is also avoided.
