Description

Technical Field

[0001] This utility model relates to the field of salt pond tarpaulin deployment and take-up technology, and in particular to an automatic rail-feeding device for salt pond tarpaulins. Background Technology

[0002] In large-scale production in salt ponds, the unfolding and retraction of salt pond tarpaulins rely on mechanical drive. The sliding parts on both sides need to slide along the slide rails on the side walls of the salt pond to achieve movement. Therefore, the stable cooperation between the slide rails and the sliding parts is the core to ensure the efficiency of tarpaulin unfolding and retraction operations.

[0003] However, traditional rail entry devices lack guidance and positioning designs for derailed sliding components. When the tarpaulin is retracted, the sliding components derail from the rail entry device and are affected by environmental factors, causing some of the sliding components to deviate from the rail entry port range. When the tarpaulin is released and the sliding components need to be re-entered, they cannot be effectively aligned with the rail entry port, requiring manual intervention. Operators need to manually adjust the position of the sliding components or manually place them into the rail entry device, which consumes a lot of manpower and seriously affects work efficiency. At the same time, operators at the edge of the salt pool face safety risks such as slippage. Therefore, there is an urgent need to provide a technical solution that can achieve automatic correction or precise rail entry of the sliding components. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, the present invention provides an automatic track-feeding device for salt pond tarpaulins.

[0005] To achieve the above objectives, this utility model provides an automatic track-feeding device for salt pond tarpaulins, comprising: The first slide rail is fixed to both sides of the salt pool and extends in the direction of tarpaulin conveying; The second slide rail has one end connected to one end of the first slide rail at an obtuse angle, and the other end extends away from the extension line of the first slide rail. The third slide rail has one end connected to the second slide rail at an obtuse angle, and the other end extends away from the extension line of the first slide rail. The third slide rail is located on the side of the second slide rail near the side wall of the salt pool. A spring sheet, one end of which is elastically connected to the third slide rail, and the other end of which extends toward the direction of the second slide rail; The first, second, and third slide rails are slidably connected to the sliding members on both sides of the tarpaulin. When the tarpaulin is being retracted, the sliding members pass sequentially through the first slide rail, the spring plate, and the third slide rail, and slide out through the third slide rail. The sliding members that slide out correspond to the third slide rail or are located within the angle range between the second and third slide rails. When the tarpaulin is being released, the sliding members that slide out enter the second and third slide rails respectively, and pass through or through the spring plate into the first slide rail.

[0006] Preferably, the second slide rail and the third slide rail are connected at an obtuse angle of 135°-150°.

[0007] Preferably, a first groove is provided on the third slide rail, the first groove is located close to the second slide rail, and is covered by the spring sheet; The first groove is for the slider to pass through, and the width of the first groove is greater than the maximum diameter of the slider. When the slider on the second slide rail enters the first slide rail, the slider arches the spring sheet and passes through the first groove.

[0008] Preferably, the rail entry device further includes a mounting frame, a floating device, and a rail entry guide fork; The two ends of the mounting frame are fixedly connected to the second slide rail and the third slide rail respectively, and the end of the mounting frame near the third slide rail is fixedly connected to the side wall of the salt pond. The guide fork for entering the rail is detachably connected to the end of the second slide rail away from the first slide rail. The floating device is set at the bottom of the mounting frame and located at the center of the mounting frame. The floating device is used to make the second slide rail and the third slide rail flush with the salt pond. The guide fork is used to guide the slider smoothly into the rail. The height of the floating device is adjustable. The rail entry device is used to raise or lower the mounting frame by changing the height of the floating device to adjust the orientation of the opening of the guide fork.

[0009] Preferably, the floating device includes an adjusting rod, an adjusting member, and a float. The adjusting rod is vertically arranged and one end is fixedly connected to the bottom of the mounting frame. The adjusting rod passes through the adjusting member and the float. The adjusting member is threadedly connected to the adjusting rod and abuts against the float. The floating device is used to adjust the position of the adjusting member on the adjusting rod, so as to adjust the length of the adjusting rod between the float and the mounting frame.

[0010] Preferably, at least two mounting brackets are provided, and one of the mounting brackets is located at the end of the second slide rail and the third slide rail; The adjusting rod is installed at the bottom of the mounting bracket furthest from the first slide rail.

[0011] Preferably, the second slide rail includes an inclined section and a horizontal section, wherein the inclined section and the horizontal section are connected at an angle; The inclined section is connected to the first slide rail at an obtuse angle, and the horizontal section is arranged parallel to the third slide rail.

The two ends of the columns are fixedly connected to the two crossbeams. The columns are all located on the side of the third slide rail away from the second slide rail.

[0015] Based on this, the beneficial effects of this utility model are as follows: This invention utilizes a design with a second slide rail, a third slide rail, and a spring plate. When the tarpaulin is retracted, the sliding parts move from the first slide rail, guided and blocked by the spring plate, into the third slide rail. As the tarpaulin is retracted, some sliding parts slide out through the third slide rail and are located outside the rail entry device. These parts may deviate from the rail entry point of the third slide rail or be affected by external environmental factors, remaining within the range between the second and third slide rails. When the tarpaulin is released, all external sliding parts automatically enter the rail via the third or second slide rail, eliminating the need for manual assistance. When the sliding parts of the second slide rail move to the spring plate position, they can arch the spring plate and pass through the third slide rail into the first slide rail, ensuring smooth tarpaulin movement and achieving fully automated operation.

[0022] Figure 1 This schematic view shows a perspective view of an orbital insertion device according to one embodiment of the present invention. Figure 2 This schematic diagram shows a top view of an orbital insertion device according to one embodiment of the present invention, such as... Figure 1 , 2 As shown, the present invention provides an automatic track-feeding device for salt pond tarpaulins, comprising: The first slide rail 10 is fixed to both sides of the salt pool and extends in the direction of conveying the tarpaulin; The second slide rail 20 has one end connected to the first slide rail 10 at an obtuse angle, and the other end extends away from the first slide rail 10. The third slide rail 30 has one end connected to the second slide rail 20 at an obtuse angle, and the other end extends away from the first slide rail 10. The third slide rail 30 is located on the side of the second slide rail 20 near the side wall of the salt pool. The spring sheet 40 has one end elastically connected to the third slide rail 30, and the other end extends toward the direction close to the second slide rail 20; The first slide rail 10, the second slide rail 20, and the third slide rail 30 are slidably connected to the sliding members 50 on both sides of the tarpaulin. When the tarpaulin is being retracted, the sliding member 50 passes through the first slide rail 10, the spring plate 40, and the third slide rail 30 in sequence, and slides out through the third slide rail 30. The sliding member 50 that slides out corresponds to the third slide rail 30 or is located within the angle range between the second slide rail 20 and the third slide rail 30. When the tarpaulin is being released, the sliding member 50 that slides out enters the second slide rail 20 and the third slide rail 30 respectively, and passes through or through the spring plate 40 into the first slide rail 10.

[0023] Specifically, in traditional technology, after the tarpaulin is recovered, the head portion of the sliding component 50 still needs to remain in the rail entry device. This design ensures that the sliding component 50 always remains associated with the rail entry device, thus providing a prerequisite for the next tarpaulin release operation. However, the derailed sliding component 50 is prone to deviating from the rail entry opening due to the lack of guidance. When the tarpaulin needs to be released and re-entered into the rail, the derailed sliding component 50 cannot be aligned with the rail entry opening, and manual intervention is still required.

[0024] In this scheme, due to the arrangement of the second slide rail 20, the third slide rail 30 and the spring plate 40, when the sliding member 50 moves from the first slide rail 10 to the roller, it will be blocked and guided by the spring plate 40 to enter the third slide rail 30, and slide out from the third slide rail 30, falling between the roller and the rail entry device. When the derailed part of the sliding member 50 is affected by external environmental factors (such as wind), due to the fixing effect of both ends of the tarpaulin (one end is located in the rail entry device, and the other end is wrapped around the roller), the derailed sliding member 50 will not be significantly derailed, and it will still be within the range between the third slide rail 30 and the second slide rail 20. When the tarpaulin releases the sliding member 50 again to enter the rail, the derailed sliding member 50 automatically enters the second slide rail 20, and the sliding member that has not derailed automatically enters the third slide rail 30. As the tarpaulin moves, the slider 50 on the third slide rail 30 is guided into the first slide rail 10 by the spring plate 40. When the slider 50 on the second slide rail 20 is in the position of the spring plate 40, it is pulled by the movement of the tarpaulin, which squeezes the spring plate 40, causing it to arch and bend towards the third slide rail 30. This allows the slider 50 to pass through the third slide rail 30 and enter the first slide rail 10, thus achieving full entry of the slider 50 into the rail and ensuring the smooth movement of the tarpaulin.

[0025] Meanwhile, in this application, the slider 50 can be a structure that combines a long rod with a ball at the head end. The long rod can be inserted into the track, and the ball can be limited by the track to prevent the slider 50 from falling out from both sides perpendicular to the sliding direction.

[0026] With this configuration, the rail-entry device of this utility model can automatically enter the rail without manual assistance, saving manpower and greatly improving the efficiency of tarpaulin operation, providing stable support for the automated operation process of tarpaulin take-up and take-down.

[0027] Furthermore, the angle between the second slide rail 20 and the third slide rail 30 is an obtuse angle ranging from 135° to 150°. In the solution of this application, the angle between the second slide rail 20 and the third slide rail 30 is 135°. Within this range, it can be fully guaranteed that even if the sliding member 50 deviates, it can still enter the second slide rail 20.

[0028] Furthermore, Figure 3 This schematic diagram illustrates the structure of the first groove according to one embodiment of the present invention, as shown below. Figure 3 As shown, a first groove 301 is provided on the third slide rail 30. The first groove 301 is located close to the second slide rail 20 and is covered by the spring sheet 40. The first groove 301 is for the slider 50 to pass through. The width of the first groove 301 is greater than the maximum diameter of the slider 50. When the slider 50 on the second slide rail 20 enters the first slide rail 10, the slider 50 arches the spring sheet 40 and passes through the first groove 301.

[0029] Specifically, the first slide rail 10, the second slide rail 20 and the third slide rail 30 are each composed of two parallel and spaced stainless steel tubes. The sliding member 50 can enter the space between the two from the opening at the end and slide along the space.

[0030] The maximum diameter of the sliding member 50 is greater than the distance between the two stainless steel tubes to prevent the sliding member 50 from derailing after entering the rail, ensuring that the tarpaulin can move smoothly. When the sliding member 50 needs to pass through the third rail 30 from the second rail 20 to enter the first rail 10, the first groove 301 ensures that the sliding member 50 can pass smoothly through the first groove 301 without being blocked or jammed by the two stainless steel tubes of the third rail 30.

[0031] Meanwhile, two spring plates 40 are provided, which are installed on the third slide rail 30 at an interval, one above the other. The gap between the two is sufficient to not affect the sliding of the horizontal sliding member 50 and to prevent the sliding member 50 from passing through longitudinally. The spring plates 40 completely cover the first groove 301, so that when the tarpaulin is retracted, the sliding member 50 on the first slide rail 10 can be blocked and guided by the spring plates 40 to enter the third slide rail 30. It will not pass through the first groove 301 and enter the second slide rail 20. This ensures that the sliding member 50 that slides out of the third slide rail 30 can still be within the range between the second slide rail 20 and the third slide rail 30 if it deviates. This ensures that the sliding member 50 will naturally and smoothly enter the rail when the tarpaulin is released next time.

[0032] Furthermore, the rail insertion device also includes a mounting frame 60, a floating device 70, and a rail insertion guide fork 80; The two ends of the mounting frame 60 are fixedly connected to the second slide rail 20 and the third slide rail 30 respectively, and the end of the mounting frame 60 near the third slide rail 30 is fixedly connected to the side wall of the salt pond. The guide fork 80 is detachably connected to the end of the second slide rail 20 away from the first slide rail 10. The floating device 70 is set at the bottom of the mounting frame 60 and located at the center of the mounting frame 60. The floating device 70 is used to make the second slide rail 20 and the third slide rail 30 flush with the salt pond. The guide fork 80 is used to guide the slider 50 smoothly into the rail. The height of the floating device 70 is adjustable. The rail entry device is used to raise or lower the mounting bracket 60 by changing the height of the floating device 70 to adjust the orientation of the opening of the guide fork 80.

[0033] Specifically, the floating device 70 includes an adjusting rod 701, an adjusting member 702, and a float 703. The adjusting rod 701 is vertically arranged and one end is fixedly connected to the bottom of the mounting frame 60. The adjusting rod 701 passes through the adjusting member 702 and the float 703. The adjusting member 702 is threadedly connected to the adjusting rod 701, and the adjusting member 702 abuts against the float 703. The floating device 70 is used to adjust the position of the adjusting member 702 on the adjusting rod 701, so as to adjust the length of the adjusting rod 701 between the float 703 and the mounting bracket 60.

[0034] Among them, the float 703 can float autonomously in the salt pool with the change of liquid level, and use the buoyancy of the water to form a stable support for the mounting frame 60, ensuring that the mounting frame 60 always maintains an appropriate height with the liquid surface of the salt pool, avoiding tilting or displacement of the mounting frame due to liquid surface fluctuations, and providing a stable structural foundation for the subsequent sliding parts to enter the rail.

[0035] The guide fork 80 is also composed of two stainless steel tubes, which are detachably connected to two stainless steel tubes spaced apart vertically on the second slide rail 20. They extend in opposite directions to form a Y-shape. The included angle between the forks of the guide fork 80 is set at 90°. Its forked shape can help to gather and guide the uneven sliding parts 50 and tarpaulin. When the height of the mounting frame 60 changes due to changes in the salt pool liquid level or the adjustment of the floating device 70, the guide fork 80 moves synchronously with the mounting frame 60. This allows the guide fork 80 to adaptively adjust the opening orientation, ensuring that the opening is always aligned with the movement trajectory of the sliding part. This ensures that the opening of the guide fork 80 can be aligned with the movement trajectory of the sliding part 50 regardless of the height of the mounting frame 60, thus improving the accuracy and stability of the sliding part 50 entering the rail.

[0036] To further improve the overall structural stability of the rail insertion device and ensure that it does not deform under stress, at least two mounting brackets 60 are provided, and one of the mounting brackets 60 is located at the end of the second slide rail 20 and the third slide rail 30. The adjusting rod 701 is installed at the bottom of the mounting bracket 60 furthest from the first slide rail 10.

[0037] Furthermore, the mounting frame 60 includes two crossbeams 601 and at least two uprights 602. The crossbeams 601 are located at the top and bottom of the second slide rail 20 and the third slide rail 30, respectively, and are fixedly connected to them. The two ends of the uprights 602 are fixedly connected to the two crossbeams 601. The uprights 602 are located on the side of the third slide rail 30 away from the second slide rail 20. Thus, the stability and rigidity of the mounting frame 60 are enhanced by the multiple uprights 602.

[0038] Furthermore, the second slide rail 20 includes an inclined section 201 and a horizontal section 202. The inclined section 201 and the horizontal section 202 are connected at an angle, with the included angle ranging from 135° to 150°. The inclined section 201 is connected to the first slide rail 10 at an obtuse angle, and the horizontal section 202 is arranged parallel to the third slide rail 30.

[0039] The horizontal section 202 buffers the slider 50, ensuring that the slider 50 slides smoothly.

[0040] Furthermore, a liner 90 is provided between the second slide rail 20 and the third slide rail 30 to limit and support the sliding member 50, preventing it from sinking excessively and getting stuck.

[0041] In summary, the rail-entry device of this utility model can automatically insert the sliding member 50 into the rail during tarpaulin recycling and release, eliminating the need for manual assistance in inserting the sliding member into the rail, saving manpower, significantly improving the efficiency of tarpaulin recycling and release, and providing a stable foundation for subsequent automated processes.

[0042] The above description is merely a preferred embodiment of this application. Those skilled in the art should understand that the scope of disclosure in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described concept.
