Description

TECHNICAL FIELD

[0002] In water conservancy projects and river measurement, a lead fish is a special measurement tool. It is a lead-made, streamlined object used to measure the flow and flow rate of a river. The lowering or retraction of the lead fish is usually completed by winding or releasing a steel wire rope through a winch. Although the weight of the lead fish will make the steel wire rope as vertical and tight as possible, under the influence of the water flow, the steel wire rope will still swing to a certain extent after entering the flow area. At present, in order to limit the swing of the steel wire rope as much as possible, only an opening through which the steel wire rope can pass is usually arranged at the bottom of the travelling crane box, and the lead fish is completely located outside the travelling crane box in both the use state and the non-use state, which occupies a large space and further limits the installation conditions and environment that can be adapted. When a space for accommodating the lead fish is arranged in the travelling crane, the rope body released by the hoisting mechanism needs to avoid the space for accommodating the lead fish, and thus the lifting monitoring mechanism for the lead fish also needs to be adaptively adjusted.

DETAILED DESCRIPTION

[0028] In order to make the purpose, method scheme and advantages of the embodiments of the present application more clear, the method scheme in the embodiments of the present application is described clearly and completely, obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0029] Embodiment 1: as Figures 1-4As shown, a full-range cableway online monitoring system comprises a lead fish lifting monitoring mechanism, the lead fish lifting monitoring mechanism comprises a rope body 1, a compression wheel 4, a guide shaft 5, a mounting plate 6, a linear bearing 7, a switch contact piece 8, a travel switch 9 and a first elastic member 10; one end of the rope body 1 is used for connecting a lead fish 2, the other end of the rope body 1 is used for connecting a winding mechanism 3; the compression wheel 4 is used for abutting against the rope body 1 in a tight state, the height of the compression wheel 4 is greater than the height of the winding mechanism 3; the compression wheel 4 is connected with the guide shaft 5 through a mounting frame 181, the guide shaft 5 is arranged in an inclined manner; one end of the guide shaft 5 away from the compression wheel 4 penetrates through the mounting plate 6; the linear bearing 7 is sleeved on the guide shaft 5, and the linear bearing 7 is located on the side of the mounting plate 6 away from the compression wheel 4; the switch contact piece 8 is sleeved on the guide shaft 5; the travel switch 9 is installed on the mounting plate 6 and located on the side of the mounting plate 6 away from the compression wheel 4, and the switch contact piece 8 is located between the travel switch 9 and the linear bearing 7; the first elastic member 10 is sleeved on the guide shaft 5; wherein when the first elastic member 10 is in a natural state, the switch contact piece 8 abuts against the contact point of the travel switch 9.

[0030] In the implementation process, the winding mechanism 3 can adopt a winch, and the rope body 1 is wound and released through the rotation of the winch. The first elastic member 10 can adopt a spring, and the first elastic member 10 can be arranged on the side of the mounting plate 6 close to the travel switch 9, or can be arranged on the side of the mounting plate 6 close to the compression wheel 4 as shown in the figure, and the two ends of the first elastic member 10 can be connected with the mounting plate 6 and the mounting frame 181 respectively. Figure 4 As shown, the travel switch 9 can adopt a micro switch. The winding mechanism 3 proposed in the embodiment is an environmental feature.

[0031] The embodiment can monitor the bottom-touching condition of the lead fish 2 through the cooperation of the compression wheel 4 and the travel switch 9 and the like. Since the lead fish 2 needs to be accommodated in the trolley, the rising height required by the lead fish 2 is greater than that in the conventional case, and then the highest point of the rope body 1 is close to the top of the trolley, and the winding mechanism 3 is generally arranged on the inner bottom wall of the trolley, so that after the rope body 1 starts from the winding mechanism 3, a section of the rope body 1 will be inclined upward as shown in the figure. Figure 2 The utility model monitors the bottom-touching condition of the lead fish 2 through the tension change of the inclined section, when the inclined section rope body 1 is tight, the rope body 1 exerts pressure on the compression wheel 4, and then the switch contact piece 8 touches the travel switch 9, when the lead fish 2 touches the bottom, the rope body 1 is no longer straight, the pressure of the rope body 1 on the compression wheel 4 decreases or disappears, and the switch contact piece 8 is away from the aforementioned contact point of the travel switch 9 under the action of the first elastic member 10. The control circuit of the travel switch 9 is turned on and off, and when the lead fish 2 touches the bottom, the release of the rope body 1 can be stopped in time.

[0032] Example 2: In order to monitor the process of lead fish 2 moving from outside the trolley to inside the trolley, the embodiment 1 is improved as shown in Figures 2-6 In this embodiment, the lead fish lifting monitoring mechanism is arranged inside the trolley, the trolley is provided with a bottom frame body 11, the bottom frame body 11 leaves a passage for the lead fish 2 to pass through, the lead fish lifting monitoring mechanism further comprises: vertical shafts 12, a moving beam 13, a limit switch 14 and a switch trigger 15, the vertical shafts 12 are at least two, the vertical shafts 12 are arranged perpendicular to the bottom frame body 11, and the vertical shafts 12 are arranged on both sides of the passage; the moving beam 13 is arranged between the two vertical shafts 12 and is in sliding connection with the vertical shafts 12, and the moving beam 13 is provided with an opening through which the rope 1 passes; the upper part of the moving beam 13 is provided with the limit switch 14; when the moving beam 13 is in a natural state, a space is left between the moving beam 13 and the limit switch 14; the switch trigger 15 is arranged on one side of the moving beam 13 close to the limit switch 14.

[0033] In the specific implementation process, the number axis can adopt an optical axis, the moving beam 13 can be connected with the optical axis through a linear bearing 7, and the switch trigger 15 can adopt a switch rocker. A stop block can also be arranged on the optical axis for limiting the downward movement of the linear bearing 7. In this embodiment, in order to enable the lead fish 2 to be hung into the cabinet, the bottom of the cabinet is designed to be open, and then a passage for the lead fish 2 to pass through is arranged. The connection mode of the lead fish 2 and the rope 1 can be as shown in Figure 2 The rope 1 and the lead fish 2 form a triangular connection area. In this embodiment, it is proposed that the lead fish 2 is an environmental feature. When the volume of the lead fish 2 is small and can be accommodated in the cabinet, the rope 1 can be wound by the winch mechanism 3 in the existing trolley, the lead fish 2 is lifted, and the lead fish 2 enters the cabinet after passing through the passage. Due to the different specifications of different lead fish 2 and the different elongation degrees of the rope 1 in different environmental use states of the lead fish 2, the length of the rope 1 is different when the lead fish 2 is retracted. In order to adapt to different use cases, the moving beam 13 is arranged in this embodiment, the lead fish 2 is lifted to push the moving beam 13 to move upward, the switch trigger 15 on the moving beam 13 cooperates with the limit switch 14 to stop the winding of the rope 1. When the volume of the lead fish 2 is large and cannot be accommodated in the cabinet.

[0034] Example 3: In order to make the moving beam 13 reset more stably, the embodiment 2 is improved as shown in Figure 6 In this embodiment, the lead fish lifting monitoring mechanism further comprises: a mounting seat 16 and a second elastic member 17, the height of the mounting seat 16 is greater than the height of the moving beam 13, and the vertical shafts 12 are mounted in the trolley through the mounting seat 16; the second elastic member 17 is sleeved on the vertical shafts 12, and the second elastic member 17 is located between the mounting seat 16 and the moving beam 13.

[0035] In the implementation process, the upper and lower ends of the vertical shaft 12 can be installed in the machine box through the mounting seat 16, and the second elastic member 17 can be connected or abutted with the moving beam 13 and the mounting seat 16 through a spring, as shown in Figure 6 When the lead sinker 2 starts to descend from the retracted state, the moving beam 13 will also descend under the action of gravity. After the second elastic member 17 is arranged between the moving beam 13 and the mounting seat 16 in the embodiment, the elastic force of the second elastic member 17 can be used to reset the moving beam 13. When the two ends of the second elastic member 17 are connected with the mounting seat 16 and the moving beam 13, the stability of the moving beam 13 during resetting can be increased, and the rapid descent of the moving beam 13 can be avoided to some extent.

[0036] Embodiment 4: In order to better limit the swing of the rope body 1, the embodiment 2 is improved, as shown in Figure 3 In the embodiment, the lead sinker lifting monitoring mechanism further comprises a limiting member 18 and a limiting block 19. The limiting member 18 is connected with the bottom wall of the moving beam 13, and the limiting member 18 is provided with a gap through which the rope body 1 passes. The limiting block 19 is connected with one end of the rope body 1 close to the lead sinker 2, and the orthographic projection of the limiting block 19 towards the gap falls at least partially on the limiting member 18.

[0037] In the implementation process, the limiting block 19 can be arranged at the vertex of the triangular connection area, as shown in Figure 2 When the limiting block 19 on the rope body 1 rises to abut against the limiting member 18, the moving beam 13 is pushed upward, the switch trigger 15 on the moving beam 13 cooperates with the limit switch 14, and the stopping of the winding of the rope body 1 is realized. When the volume of the lead sinker 2 is large and cannot be accommodated in the machine box, the limiting member 185 in the embodiment is used to control the upward height of the triangular connection area, so that the triangular connection area is accommodated in the travelling crane, and the control process is the same as described above. Figure 2

[0038] Since the machine box of the travelling crane provided in the embodiment does not have a lower bottom, the swing of the rope body 1 cannot be limited through the opening in the lower bottom as in the prior art. Therefore, the limiting member 18 in the embodiment also has the function of limiting the swing of the rope body 1 through the size of the gap.

[0039] Embodiment 5: In order to reduce the wear of the rope body 1 and further limit the swing of the rope body 1, the embodiment 4 is improved, as shown in Figure 3 ​As shown, in the embodiment, the limiting member 18 comprises a mounting frame 181 and a pipe body 182, the mounting frame 181 is connected with the moving beam 13, the mounting frame 181 is located below the moving beam 13, and the mounting frame 181 is provided with a through hole for the rope 1 to pass through; the pipe body 182 is at least two, and the gap is formed between the two pipe bodies 182, the pipe body 182 is mounted on the mounting frame 181, and the pipe body 182 is located below the through hole.

[0040] In the implementation process, the mounting frame 181 can be a U-shaped frame body, and the pipe body 182 can be a circular steel pipe. The rope 1 passes through the gap between the two pipe bodies 182 and the opening on the moving beam 13 in turn, and the opening on the moving beam 13 and the pipe body 182 can limit the movement of the rope 1. At the same time, the rope 1 can abut or rub against the pipe body 182 during use. The pipe body 182 with a circular cross section can reduce the friction between the rope 1 and the pipe body 182, thereby reducing the wear of the rope 1. The limiting block 19 on the rope 1 cannot pass between the two pipe bodies 182, so that the limiting block 19 on the rope 1 can push the pipe body 182 from below during the lifting of the lead fish 2, thereby moving the moving beam 13 upward.

[0041] Because the length of the gap between the two pipe bodies 182 is relatively long, the limitation on the rope 1 is limited, so the aperture of the opening on the moving beam 13 can be smaller. However, because the aperture is small, the rope 1 will often rub against it, such as when the rope 1 is vertically suspended with the lead fish 2. When the lead fish 2 is lowered into the river water, a horizontal pushing force is exerted on the lead fish 2 due to the flow of the water body, the relative vertical position of the lead fish 2 changes, thereby causing the rope 1 to tilt. A protective sleeve can be sleeved in the aperture, and the protective sleeve can reduce the wear caused by the lifting of the rope 1 during tilting. The protective sleeve can be made of a non-rigid material, such as rubber.

[0042] Embodiment 6: In order to better monitor the movement of the rope 1, the embodiment 2 is improved, as shown in Figure 2 As shown, in the embodiment, the lead fish lifting monitoring mechanism further comprises an encoder wheel 20, the height of the encoder wheel 20 is greater than that of the moving beam 13, and the height of the compression wheel 4 is less than that of the encoder wheel 20; the rope 1 is released from the winch mechanism 3 and wound around the encoder wheel 20; the rope 1 passes through the opening of the moving beam 13 after passing through the encoder wheel 20; the compression wheel 4 abuts against the tight rope 1 on the side close to the winch mechanism 3 of the encoder wheel 20.

[0043] In the embodiment, the encoder wheel 20 is connected with the rotary encoder 30, which is a sensor that detects the position, direction and speed of a shaft or a rotating body by converting the rotary motion into an electrical signal. The encoder wheel 20 is provided with special marks or openings, which change the path of light, magnetism or electricity when the wheel rotates, and then are read by the encoder 30 and converted into a digital signal. As shown in Figure 2 FIG. 1, the rope 1 extends vertically downward through the opening of the moving beam 13 after passing through the encoder wheel 20. The encoder wheel 20 can also serve as a guide for the extension path of the rope 1.

[0044] Embodiment 7: In order to better arrange the lead fish lifting monitoring mechanism, the embodiment is improved on the basis of embodiment 6, as shown in Figure 2 and Figure 5 In the embodiment, the online monitoring system comprises a portal frame 21, the encoder wheel 20 is installed below the cross beam of the portal frame 21, one end of the mounting plate 6 is connected with the cross beam of the portal frame 21, and the other end of the mounting plate 6 gradually decreases in height during the extension towards the hoisting mechanism 3.

[0045] In the embodiment, the encoder wheel 20 and the mounting plate 6 are both connected with the cross beam of the portal frame 21, which can better ensure the relative positions among the encoder wheel 20, the compression wheel 4, the hoisting mechanism 3 and the rope 1, so that the rope 1 in the straightened state and the compression wheel 4 can be in a mutual extrusion state and the extrusion position is as close to the middle part of the compression wheel 4 as possible.

[0046] Embodiment 8: In order to better control the movement of the trolley, the embodiment is improved on the basis of embodiments 1-7, as shown in Figures 7-9 In the embodiment, the online monitoring system comprises a trolley movement monitoring mechanism, the trolley movement monitoring mechanism comprises a guide rail 22, an abutting block 23 and an abutting switch 24, the guide rail 22 is used to be connected with the trolley in rolling manner, the abutting block 23 is arranged at both ends of the guide rail 22, and the abutting switch 24 is arranged at both ends of the bottom of the trolley; when the trolley moves to the preset path endpoint, the abutting block 23 abuts against the abutting switch 24.

[0047] In practical implementation, to better demonstrate the cooperation between the abutment blocks 23 on the guide rail 22 and the trolley, the guide rail 22 in the attached drawings of this utility model is relatively short. In actual use, the distance between the abutment blocks 23 at both ends of the guide rail 22 is much greater than the length of the trolley. When the trolley moves on the guide rail 22, its movement is limited by the cooperation of the limit block 19 and the limit switch 14. The guide rail 22 can span waterways, and the trolley can be self-driving, with a drive motor installed on the trolley to drive the wheels to roll along the guide rail 22. Charging devices can also be installed on both banks of the waterway, with charging brushes installed on the trolley, and charging of the trolley is achieved through contact connection. When the trolley moves to the abutment block 23, the rocker arm on the abutment switch 24 abuts against the abutment block 23, and the rocker arm rotates. When an external force is applied to the rocker arm, the rocker arm swings. This swing is converted into the action of the contact points through an internal mechanism, that is, the closing or opening of the contact points. Specifically, when the joystick swings to a predetermined position, the contacts close, thus connecting the circuit; when the joystick leaves that position, the contacts open, and the circuit is broken. This process enables precise control of the circuit, thereby controlling the movement of the vehicle.

[0048] Example 9: To better monitor the vehicle's movement, such as... Figures 7-9 As shown, in this embodiment, the vehicle movement monitoring mechanism further includes: a bearing seat 25, a connecting shaft 26, a self-driving wheel 27, and a driven wheel 28. The bearing seat 25 is used to connect with the bottom wall of the vehicle; the connecting shaft 26 is rotatably connected to the bearing seat 25 via a bearing; there are at least two self-driving wheels 27, which are connected via the connecting shaft 26 and connected to the rollers of the guide rail 22; there are at least two driven wheels 28, which are connected via the connecting shaft 26, and the driven wheels 28 and the self-driving wheels 27 are respectively located at the front and rear ends of the vehicle. The vehicle movement monitoring mechanism further includes: a driving gear 29, an encoder 30, and a driven gear 31. The driving gear 29 is provided on the connecting shaft 26 corresponding to the driven wheel 28; the encoder 30 is installed below the bottom frame 11; the driven gear 31 is connected to the encoder 30 and is drively connected to the driving gear 29.

[0049] In practice, the connecting shaft 26 of the self-driving wheel 27 can be connected to a rotary motor. The rotary motor drives the self-driving wheel 27 to rotate, and the self-driving wheel 27 drives the driven wheel 28 to move, thereby realizing the movement of the vehicle. Through the transmission of the driving gear 29 and the driven gear 31, the encoder 30 can detect the rotation angle of the transmission gear, thereby monitoring and controlling the position and motion state, and realizing high-precision positioning, operation and status feedback of the vehicle.

[0050] The above merely is preferred embodiment of the present utility model, and is not used to limit the present utility model, for the method personnel in the art, the present utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the present utility model, should be contained in the protection scope of the present utility model.
