DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0022] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, the accompanying drawings only show structures and / or processing steps that are closely related to the solutions according to the present invention, while other details that are not closely related to the present invention are omitted.

[0023] like Figure 1 、 Figure 2 As shown, this specific embodiment adopts the following technical scheme: it includes a support 1, a permanent magnet direct drive motor 2, a drum body 3, a pin 4, a flexible pull rod 5, a tensioning device 6, a ground roller 7, a connecting plate 8 and a car compartment 9; a pair of supports 1 are fixedly installed on the car compartment 9, and the supports 1 are fixedly connected to the stator on the permanent magnet direct drive motor 2, and the outer rotor of the permanent magnet direct drive motor 2 is fixedly sleeved with a drum body 3, and both ends of the drum body 3 are fixedly installed with a disk cover, and the support 1 is inserted with a pin 4, and the pin 4 is plugged into the disk cover on the side of the drum body 3, and the two ends of the flexible pull rod 5 are respectively rotationally connected to the central axis of the permanent magnet direct drive motor 2 and the ground roller 7, and the ground roller 7 is connected to the tensioning device 6 through the connecting plate 8.

[0024] The permanent magnet direct drive outer rotor motor rotates, driving the drum body 3 to rotate through the connection, realizing multiple layers of long-haired blanket winding, or reverse to achieve blanket laying. When the work is completed, the drum body 3 is inserted with the pin 4. Due to the uncertainty of the field site, to avoid adverse working factors such as impact on the working drum body 3, a flexible pull rod 5 is set between the drum body 3 and the ground roller 7.

[0025] like Figure 3 As shown, further, the tensioning device 6 includes a mounting plate 61, a fixed roller 62, an adjusting roller 63 and a proximity switch 64; a pair of fixed rollers 62 are rotatably mounted on a pair of mounting plates 61, and an adjusting roller 63 is mounted at the middle and lower ends of the pair of fixed rollers 62. The adjusting roller 63 can rotate freely and can move up and down on the mounting plate 61. A pair of proximity switches 64 are fixedly mounted on the mounting plate 61, and the pair of proximity switches 64 are respectively located at the upper and lower ends of the adjusting roller 63.

[0026] When the adjusting roller 63 on the tensioning device 6 is at the extreme positions at both ends, there will be an appropriate distance between the adjusting roller 63 and the proximity switch 64 (that is, the adjusting roller 63 will not touch the proximity switch 64). When the tension of the blanket on the tensioning device 6 is large, the adjusting roller 63 rises and the upper proximity switch 64 senses it. On the contrary, when the tension is small, the adjusting roller 63 falls and the lower proximity switch 64 senses it. The information is fed back to the control system 12 through the proximity switch 64, and then the control system 12 controls the permanent magnet direct drive motor 2 to adjust the speed in real time to ensure that the speed of winding and laying the blanket is synchronized with the car.

[0027] Furthermore, the side disc cover of the reel body 3 is evenly distributed with several pin holes that cooperate with the pin 4; the electrical control can achieve zero-speed braking of the permanent magnet motor, and through the cooperation between the pin 4 and the pin hole, mechanical braking can be achieved, achieving double insurance of mechanical and electrical braking.

[0028] Furthermore, a spring is provided in the middle of the flexible pull rod 5; the winding machine body is connected to the ground roller through the flexible pull rod 5, so that the main body's retraction and release of the blanket will not be affected by the uneven ground. At the same time, the ground roller 7 presses the blanket on the ground with its own weight, so that the blanket will not be suspended in the air.

[0029] like Figure 4 As shown, further, the permanent magnet direct drive motor 2 and the proximity switch 64 are both electrically connected to the control system 12, and the control system 12 is electrically connected to the vehicle speed sensor 11; the permanent magnet direct drive motor 2 is lengthened, and the width of the outer rotor of the permanent magnet direct drive motor 2 is consistent with the width of the blanket.

[0030] In terms of electrical control, the vehicle speed sensor 11 is used to synchronize the vehicle's running speed. At the same time, the data from the proximity switch 64 is combined to control the permanent magnet direct drive motor 2 to adjust the speed in real time to ensure that the speed of winding and laying the blanket is synchronized with the car.

[0031] like Figure 5 As shown, further, a frame bracket 10 is fixedly installed on the automobile compartment 9; the frame bracket 10 is an inverted trapezoidal structure.

[0032] When the width of the blanket winder is larger than the car compartment, a frame bracket 10 is installed on the car compartment 9 to form an inverted trapezoidal structure, and then the blanket winder is installed on the frame bracket 10 so that the main body is suspended outside the car compartment for operation.

[0033] The working principle of this embodiment is as follows: first, the blanket winding machine is installed on the car compartment 9, and then the blanket on the reel body 3 is pulled out from the bottom, and passes through the fixed roller 62, the adjusting roller 63, the fixed roller 62 and the ground roller 7 in sequence, and then the tail end of the blanket is fixed by the anchoring device (such as Figure 2As the vehicle moves forward, the permanent magnet direct-drive outer rotor motor drives the reel 3 to rotate, which in turn drives the reeling and unreeling of the blanket. The electrical control system monitors the vehicle's speed and, based on data from the proximity switch 64, controls the permanent magnet direct-drive motor 2, adjusting its speed in real time to ensure that the blanket reeling and laying speeds are synchronized with the vehicle's.

[0034] The present invention installs a winder on a car compartment and realizes the winding and unwinding of the blanket by the forward and reverse rotation of the drum, which not only reduces the labor intensity of the soldiers, but also reduces the time for laying and rolling up the blanket; the saved time can be used for soldiers' training to improve their combat effectiveness; the use of a permanent magnet variable frequency motor can improve efficiency and reduce electricity expenses, etc.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
