Description

Technical Field

[0001] The present invention relates to the technical field of radar ranging equipment, and in particular to a radar ranging device for sports venues. Background Art

[0002] Sports venues refer to special land with fixed facilities and equipment that can be used for physical fitness, teaching, training and competition, including public sports venues open to the public and non-public sports venues used within units. During the construction of sports venues, in order to ensure quality, it is necessary to plan the distance measurement of the construction site in advance. Among them, the most common distance measurement method is to use radar.

[0003] The construction of sports venues usually involves infrastructure construction around a runway, and the requirements for marking the arc ends of the runway are the most stringent. Before manually pushing a cart to mark the arc runway, workers need to lay out the lines on the runway in advance. The main methods of existing line laying are point laying and arc laying. The former requires the user to place the ranging radar at the center of the arc runway in advance, and calculate the starting point, end point and midpoint of the arc runway through the ranging radar, and then roughly lay out the lines. The latter requires the user to calculate the placement point in advance through the ranging radar (the center of the arc runway, according to different The laying-out size will have different points) and the ranging radar is fixed. The position of the ranging radar is used as one end, and the wire roll is manually stretched and moved along the runway to draw a dotted line to facilitate the subsequent wiring operation of the workers. However, in actual operation, this method requires manual marking of the points after the radar ranging is done. Manual marking will result in a certain degree of accuracy difference in the obtained marking line. On the other hand, since the curved runway usually covers a large area, the worker needs to bend over and mark the line while moving during the manual rolling of the marking line. Long-term work will make the workers feel very tired, and the convenience needs to be improved. Summary of the Invention

[0004] The present invention discloses a radar ranging device for sports venues, which aims to solve the technical problems that, after the existing ranging radar performs mark distance measurement on the curved end of a runway, on the one hand, it is necessary to manually mark the points, and manual marking will result in a certain degree of accuracy difference in the obtained marking line; on the other hand, since the curved runway usually covers a large area, during the process of manually rolling the marking line, workers need to bend over and mark the line while moving, and the long-term operation will make the workers feel very tired, and the convenience needs to be improved.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A sports field radar ranging device includes a bracket, a radar fixed to the top of the bracket, and an electric pay-off roller distributed on the outside of the machine. The radar measures the wiring distance and controls the electric pay-off roller to release the traction line of the corresponding distance through a controller;

[0007] A cleaning assembly is provided on the side of the electric pay-off roller, and the cleaning assembly is used to clean the traction line of the electric pay-off roller;

[0008] A moving mechanism is provided inside the machine; a wiring mechanism is provided inside the moving mechanism; and a lifting mechanism is provided between the machine and the electric pay-off roller;

[0009] The lifting mechanism and the machine cooperate with the movement of the moving mechanism to lay out the wires. After the moving mechanism moves to a specified distance, the moving mechanism is used to change direction to drive the wiring mechanism to apply paint to the runway and perform wiring work.

[0010] A machine structure rotatably mounted on the bottom of the bracket is provided on the basis of the traditional ranging radar, and a moving mechanism is placed inside the machine. After the radar completes the ranging, the line is paid off by the electric pay-off roller in coordination with the lateral and longitudinal movement of the moving mechanism. The electric pay-off roller pulls the moving mechanism with the traction line, causing the moving mechanism to move along the arc track on the arc runway. While moving, it drives the operation of the additional wiring mechanism, so that a white dotted line is generated on the route where the mobile mechanism has run, thereby replacing the operation of manual marking and laying out the line, greatly improving the functionality of the traditional ranging radar, and at the same time improving the accuracy of subsequent marking and improving the convenience of marking. At the same time, the additional lifting mechanism can increase the height of the line end connected to the electric pay-off roller and the moving mechanism, thereby further improving the stability of this equipment during operation.

[0011] The transmission mechanism is a pair of pair of pair of opposite ends of the sprocket wheel, the side of the pair of opposite ends is engaged with the gear train of said frame, and said pair of opposite ends is engaged with the gear train of said frame, and said pair of opposite ends is engaged with the gear train of said frame.

[0012] By separately setting a bottom plate with bottom wheels and a transport platform structure with top wheels, using a motor to drive the transmission of the bevel gear in conjunction with the ordinary gear, and then using an electric push rod to drive the transport platform to rise and fall, the gears connected to the bottom wheel and the top wheel are driven by the motor respectively, so that the rotation of the bottom wheel and the top wheel drives the wiring mechanism to move, and move longitudinally and transversely, cooperating with the operation of the wiring mechanism to complete the laying of the curved runway, replacing manual marking and improving the accuracy and convenience of marking.

[0013] In a preferred embodiment, the wiring mechanism includes a circular bin fixedly mounted on one end of the top of the transport platform. The circular bin is a hollow structure and passes through the bottom of the transport platform. The top of the circular bin is connected to a barrel. At the same time, a discharge wheel is rotatably mounted inside the circular bin, and the discharge wheel is fixedly connected to the side of one of the top wheels.

[0014] By setting up a circular bin with an internal discharge wheel structure, the rotation of the top wheel is used to drive the discharge wheel to rotate synchronously. While rotating, the paint inside the barrel connected to the top of the circular bin is intermittently discharged, and in conjunction with the operation of the moving mechanism, an arc-shaped dotted line is formed, which facilitates the workers' subsequent marking operations and ensures the perfect and reasonable operation of this equipment.

[0015] In a preferred embodiment, the cleaning component includes two cotton rollers symmetrically distributed on the sides of the electric pay-off roller, and the traction line of the electric pay-off roller passes between the cotton rollers to clean the traction line. The lifting mechanism includes a sliding groove opened on both sides of one end of the machine, and a sliding plate is slidably installed inside the sliding groove. The electric pay-off roller and the cotton roller are both rotatably installed between the two sliding plates. An adapter is rotatably installed on the top of the transport platform, and a lifting rod is rotatably installed on the top of the adapter. One end of the lifting rod is connected and fixed to the traction line of the electric pay-off roller.

[0016] By setting the electric pay-off roller to be rotatably connected to the middle part of the sliding plate, and additionally providing a foldable lifting rod structure on the top of the moving mechanism, the pulling force of the electric pay-off roller on the moving mechanism when winding the traction line, and the resetting rotational force of the lifting rod when releasing the line segment are utilized, so that the traction line connected by the electric pay-off roller and the moving mechanism can be lifted, and the line end is prevented from contacting the ground, thereby preventing debris on the ground from blocking the pay-off operation of the electric pay-off roller, thereby affecting the operation of this equipment, and ensuring the integrity of the operation of this equipment.

[0017] In a preferred solution, an elastic member is fixedly connected between each of the sliding grooves and the interlayer of the sliding plate, a torsion spring is fixedly connected between the interlayer of the adapter and the raising rod, and both ends of the torsion spring are respectively connected to the adapter and the raising rod.

[0018] The elastic part and the torsion spring structure are provided to provide power for the lifting of the electric pay-off roller and the lifting rod, thereby ensuring the perfect and reasonable operation of the lifting mechanism.

[0019] In a preferred embodiment, an emptying port is opened in the upper middle part of the machine, and the folded lifting rod passes through the inside of the emptying port. A retaining port is opened on the upper side of the machine, and the barrel passes through the inside of the retaining port.

[0020] By respectively providing an emptying port and a retaining port structure, when the moving mechanism is stored inside the machine, the emptying port and the retaining port are utilized to provide space for storing the lifting rod and the barrel, thereby ensuring the integrity and rationality of the operation of the equipment.

[0021] As can be seen from the above, the sports field radar ranging device provided by the present invention has the following improvements and advantages compared with the prior art:

[0022] By setting up a mechanism that can automatically pay out the arc line on the basis of the traditional ranging radar, when the radar completes the ranging, the line is paid out by the electric pay-out roller, and then the bottom plate with bottom wheels and the transport platform structure with top wheels are used. The motor drives the bevel gear to cooperate with the ordinary gear for transmission, and then the electric push rod is used to drive the transport platform to rise and fall, so that it moves through the rotation of the bottom wheel and the top wheel, and moves longitudinally and laterally. After reaching the designated position, it moves in an arc trajectory. At the same time, a circular warehouse structure with a discharge wheel inside is additionally provided, and the rotation of the top wheel is used to drive the discharge wheel to rotate synchronously. While rotating, the paint inside the barrel connected to the top of the circular warehouse is intermittently discharged, and in conjunction with the operation of the transport platform, an arc-shaped white dotted line is formed on the runway, thereby facilitating the workers' subsequent marking operations, replacing manual marking, improving the accuracy and convenience of marking, and improving the functionality of traditional ranging radars.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The invention discloses a radar ranging device for sports venues, which is mainly used for measuring the distance markings of curved runways in sports venues.

[0035] Reference Figures 1 to 9 A sports field radar ranging device includes a bracket 1, a radar 2 fixed to the top of the bracket 1, a machine platform 3 rotatably mounted on the bottom of the bracket 1, and electric pay-off rollers 4 distributed on the outside of the machine platform 3. The radar 2 measures the wiring distance and controls the electric pay-off rollers 4 to release the traction line of the corresponding distance through a controller;

[0036] A cleaning assembly is provided on the side of the electric pay-off roller 4, which is used to clean the traction line of the electric pay-off roller 4;

[0037] A moving mechanism 6 is provided inside the machine 3; a wiring mechanism 7 is provided inside the moving mechanism 6; a lifting mechanism 8 is provided between the machine 3 and the electric pay-off roller 4;

[0038] The lifting mechanism 8 and the machine 3 cooperate with the movement of the moving mechanism 6 to pay out the wire. After the moving mechanism 6 moves to the specified distance, the moving mechanism 6 is used to change direction to drive the wiring mechanism 7 to apply paint to the runway and perform wiring work. The cleaning component includes two cotton rollers 5 symmetrically distributed on the sides of the electric pay-off roller 4. The traction line of the electric pay-off roller 4 passes between the cotton rollers 5 to clean the traction line.

[0039] In this embodiment: after the user holds the bracket 1 and moves it to the designated position of the runway (the center of the arc-shaped runway), the bracket 1 is opened and placed vertically on the ground, and the radar 2 is started at the same time. The radar 2 model is RPLIDAR A3. The straight-line distance to the arc-shaped runway is measured by the radar 2. At this time, the user can rotate the machine 3 and face the end point of the arc-shaped runway, and at the same time control the electric pay-off roller 4 to run to release the corresponding length of the line segment and start the moving mechanism 6. While the electric pay-off roller 4 is paying off the line, the two symmetrically distributed cotton rollers 5 will continuously clean the line segment. The started moving mechanism 6 moves horizontally until it reaches the length of the line segment released by the electric pay-off roller 4. At this time, the line released by the electric pay-off roller 4 is pulled straight, and the moving mechanism 6 also changes from the original horizontal movement to the longitudinal movement. Since the longitudinally moving moving mechanism 6 is pulled by the electric pay-off roller 4 to release the line segment, the moving mechanism 6 will produce an arc movement around the bracket 1 as the center of the circle, and the wiring mechanism 7 will be started synchronously while moving, so that as the moving mechanism 6 moves, the white dotted line is laid on the arc runway to complete the wiring work; in the process of the electric pay-off roller 4 rotating and releasing the line segment, the lifting mechanism 8 will run synchronously, thereby lifting the released line segment for a distance and allowing the line segment to be suspended in the air to prevent the line segment from being obstructed by ground obstacles when the moving mechanism 6 is running.

[0040] It should be supplemented that: a stopper 12 is sleeved and installed on both sides of the middle of the cotton roller 5, which is used to position the wire segment released by the electric pay-off roller 4.

[0041] In the above scheme, in order to replace the manual work of laying out the curved runway, the specific operations are as follows.

[0042] Reference Figures 2 to 4 、 Figures 6 to 9In a preferred embodiment, the moving mechanism 6 includes a bottom plate 601 distributed inside the machine 3, and a plurality of bottom wheels 602 are symmetrically and rotatably installed on both sides of the bottom plate 601. The plurality of bottom wheels 602 are in contact with the ground, and a common gear 603 is fixed horizontally on the side of one bottom wheel 602. A motor 604 is fixed on the top of the bottom plate 601, and a first bevel gear 605 is fixed on the output end of the motor 604. The common gear 603 and the first bevel gear 605 are meshed and connected. A transport platform 606 is distributed on the top of the bottom plate 601. The transport platform 606 06 are symmetrically and rotatably installed on both sides of the transport platform 606. A second bevel gear 608 is rotatably installed on the inner wall of the transport platform 606. A belt 609 is connected between the second bevel gear 608 and a top wheel 607. The relatively moving first bevel gear 605 is meshed with the second bevel gear 608, and an electric push rod 610 is vertically fixed in the middle of the transport platform 606. The output end of the electric push rod 610 vertically passes through the transport platform 606 and is connected and fixed to the top of the base plate 601; the wiring mechanism 7 is arranged on the top of the transport platform 606.

[0043] In this embodiment: the user rotates the machine 3 toward the end point of the arc runway, and at the same time controls the electric pay-off roller 4 to run, pays out a line segment of corresponding length and starts the motor 604 at the same time, causing the motor 604 to rotate and drive the first bevel gear 605 to rotate synchronously. The rotating first bevel gear 605 drives the bottom wheel 602 to rotate through the meshing ordinary gear 603, and the rotating bottom wheel 602 drives the bottom plate 601 to move laterally, thereby driving the entire moving mechanism 6 to move toward the end point of the arc runway until it moves to the position corresponding to the maximum length of the line segment paid out by the electric pay-off roller 4. At this time, the line segment paid out by the electric pay-off roller 4 is pulled and straightened, and the electric push rod 610 When the machine starts working, the entire bottom plate 601 is lifted by retracting the output shaft, causing the bottom wheel 602 to lose contact with the ground and allowing the top wheel 607 to contact the ground. At the same time, the first bevel gear 605 that moves synchronously will mesh with the second bevel gear 608 and drive the second bevel gear 608 to rotate. The rotating second bevel gear 608 will drive the top wheel 607 to rotate through the belt 609. The rotating top wheel 607 will drive the entire transport platform 606 to move longitudinally, and the entire moving mechanism 6 is pulled by the line segment released by the electric pay-off roller 4, so that it can only move in a circular trajectory around the electric pay-off roller 4 as the center of the circle, thereby moving along the arc runway; Figure 9 shown.

[0044] In the above scheme, in order to lay the line on the curved runway in advance and facilitate subsequent operators to mark the solid line, the specific operations are as follows.

[0045] Reference Figures 2 to 4 、 Figures 6 to 8In a preferred embodiment, the wiring mechanism 7 includes a circular bin 701 fixedly mounted on one end of the top of the transport platform 606. The circular bin 701 is a hollow structure and passes through the bottom of the transport platform 606. The top of the circular bin 701 is connected with a barrel 702. At the same time, a discharge wheel 703 is rotatably installed inside the circular bin 701. The discharge wheel 703 is fixedly connected to the side of a top wheel 607.

[0046] In this embodiment: when the entire moving mechanism 6 is driven and moved by the rotating top wheel 607, the rotating top wheel 607 will drive the unloading wheel 703 to rotate synchronously, and the continuously rotating unloading wheel 703 will intermittently open the connection between the circular bin 701 and the barrel 702, thereby intermittently discharging the paint inside the barrel 702 and leaving it on the curved runway, cooperating with the operation of the moving mechanism 6, leaving intermittent dotted lines on the curved runway.

[0047] In the above scheme, considering that when the mobile mechanism 6 moves along the runway, the line segment connecting the electric pay-off roller 4 and the mobile mechanism 6 will be blocked by obstacles on the ground, therefore, in order to ensure the integrity of the operation of this equipment, the specific operations are as follows.

[0048] Reference Figures 1 to 7 In a preferred embodiment, the lifting mechanism 8 includes a sliding groove 801 opened on both sides of one end of the machine 3, and a sliding plate 802 is slidably installed inside the sliding groove 801. The electric pay-off roller 4 and the cotton roller 5 are both rotatably installed between the two sliding plates 802. The top of the transport platform 606 is rotatably installed with an adapter 803, and the top of the adapter 803 is rotatably installed with a lifting rod 804. One end of the lifting rod 804 is fixedly connected to the traction line of the electric pay-off roller 4.

[0049] In this embodiment: when the moving mechanism 6 is located inside the machine 3, since the wire segment inside the electric pay-off roller 4 is tightly wound, there will be a pulling force between the sliding plate 802 and the lifting rod 804, so that the electric pay-off roller 4 is located at the bottom of the sliding groove 801, and the lifting rod 804 is pulled by the wire segment and is in a flat state. When the moving mechanism 6 starts to move and the electric pay-off roller 4 starts to perform the pay-off operation, the pulling force between the electric pay-off roller 4 and the lifting rod 804 is lost, and the sliding plate 802 moves upward along the inside of the sliding groove 801, and the lifting rod 804 rotates synchronously, thereby lifting the wire segment connected between the electric pay-off roller 4 and the moving mechanism 6, so that the wire segment will not directly contact the ground, thereby preventing the wire segment from being blocked by ground obstacles.

[0050] Among them, it needs to be supplemented that: an elastic member 805 is fixedly connected between the interlayer of each sliding groove 801 and the sliding plate 802, and a torsion spring 806 is fixedly connected between the interlayer of the adapter 803 and the raising rod 804, and the two ends of the torsion spring 806 are respectively connected to the adapter 803 and the raising rod 804; when the sliding plate 802 and the raising rod 804 lose the pulling force limit, the elastic member 805 and the torsion spring 806 will provide driving force for the sliding plate 802 and the raising rod 804 respectively, allowing the sliding plate 802 to slide upward along the sliding groove 801 and allowing the flat raising rod 804 to rotate upright.

[0051] Furthermore, it is supplemented that: an emptying port 9 is opened in the upper middle part of the machine 3, and the folded lifting rod 804 passes through the inside of the emptying port 9; a retaining port 10 is opened on the upper side of the machine 3, and the barrel 702 passes through the inside of the retaining port 10; the emptying port 9 and the retaining port 10 provide space for the movement of the lifting rod 804 and the barrel 702 respectively.

[0052] In the above solution, considering that the moving mechanism 6 is reset after completing its work, in order to facilitate the moving mechanism 6 to return to the interior of the machine 3, the specific operation is as follows.

[0053] Reference Figures 2 to 4 In a preferred embodiment, a positioning groove 11 is opened at the bottom of the inner wall of the machine 3, and the bottom wheel 602 is distributed inside the positioning groove 11.

[0054] In this embodiment, when the moving mechanism 6 is reset and moved to the side of the platform 3 , the positioning groove 11 will guide the movement of the bottom wheel 602 , thereby making it easier for the moving mechanism 6 to return to the interior of the platform 3 .

[0055] Working principle: When in use, the user holds the bracket 1 and moves it to the designated position of the runway (the center of the arc runway), expands the bracket 1 and places it vertically on the ground, and starts the radar 2 at the same time. The radar 2 measures the straight-line distance to the arc runway. At this time, the user can rotate the machine 3 and face the end point of the arc runway, and control the electric pay-off roller 4 to run and release the line segment of corresponding length. While the electric pay-off roller 4 is paying off the line, the two symmetrically distributed cotton rollers 5 will continuously clean the line segment, and the motor 604 is started synchronously, causing the motor 604 to rotate and drive the first bevel gear 605 to rotate synchronously, rotating The first bevel gear 605 will drive the bottom wheel 602 to rotate through the meshing ordinary gear 603, and the rotating bottom wheel 602 will drive the bottom plate 601 to move horizontally, thereby driving the entire moving mechanism 6 to move toward the end point of the arc runway until it moves to the position corresponding to the maximum length of the line segment released by the electric pay-off roller 4. At this time, the line segment released by the electric pay-off roller 4 is pulled and straightened, and the electric push rod 610 starts to work, and the entire bottom plate 601 is lifted by retracting the output shaft, causing the bottom wheel 602 to lose contact with the ground and allowing the top wheel 607 to contact the ground, and the first bevel gear 605 of the rotating bevel gear 605 to rotate will cause the bottom wheel 602 to lose contact with the ground and allow ... The wheel 605 will mesh with the second bevel gear 608 and drive the second bevel gear 608 to rotate. The rotating second bevel gear 608 will drive the top wheel 607 to rotate through the belt 609. The rotating top wheel 607 will drive the entire transport platform 606 to move longitudinally, and the entire moving mechanism 6 is pulled by the line segment released by the electric pay-off roller 4, so that it can only move in a circular trajectory around the electric pay-off roller 4 as the center of the circle, and walk along the arc runway. The rotating top wheel 607 will drive the unloading wheel 703 to rotate synchronously, and the continuously rotating unloading wheel 703 will intermittently open the circular bin 701 and the barrel 70 2, thereby intermittently guiding the paint inside the barrel 702 and leaving it on the arc runway, cooperating with the operation of the moving mechanism 6, leaving intermittent dotted lines on the arc runway, and completing the routing work; and when the electric pay-off roller 4 starts to pay-off operation, the electric pay-off roller 4 and the lifting rod 804 lose the influence of the pulling force, the sliding plate 802 will move upward along the inside of the sliding groove 801, and the lifting rod 804 will rotate synchronously, thereby lifting the line segment connected between the electric pay-off roller 4 and the moving mechanism 6, so that the line segment will not directly contact the ground, thereby preventing the line segment from being blocked by ground obstacles.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
