Technical Field

[0001] This utility model relates to the field of tarpaulin winch technology, and in particular to a tracked chassis folding arm canopy sealing device. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to tarpaulin winches is also constantly improving. Tarpaulin winches are key equipment for material protection and covering operations, and are widely used in construction, cargo transportation, and open-air storage. Their core function is to use a motor to drive the roller to realize the raising and lowering of the tarpaulin, thereby quickly completing the covering or exposure operation of the target area.

[0003] Currently used tarpaulin winches can generally only complete the winding and unwinding of tarpaulins, but their winding shafts are difficult to adjust and adapt flexibly according to the height that the tarpaulin needs to cover. As a result, when covering materials or places that are high or low, the fit of the tarpaulin is easily affected and reduced, which has an adverse effect on the actual use of the tarpaulin winch. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the tarpaulin winches currently used can generally only complete the winding and unwinding of tarpaulins, but their winding shafts are difficult to flexibly adjust and adapt according to the height to be covered by the tarpaulin. As a result, when covering materials or places that are higher or lower, the fit of the tarpaulin is easily affected and reduced, which has an adverse effect on the actual use of the tarpaulin winch. Therefore, a tracked chassis folding arm tarpaulin sealing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tracked chassis folding arm canopy sealing device includes a tracked vehicle, a frame fixedly mounted on the tracked vehicle, a support base fixedly mounted on the frame, a first rotating shaft and a second rotating shaft rotatably connected to the support base, a rotating arm fixedly connected to the first rotating shaft, an electric push rod fixedly connected to the second rotating shaft, a third rotating shaft rotatably connected to the drive end of the electric push rod, and the third rotating shaft and the rotating arm fixedly connected. A support arm is fixedly mounted on the rotating arm, and a servo motor is fixedly mounted on the support arm. A winding shaft is fixedly connected to the drive end of the servo motor, and an electromagnetic brake is provided at the drive end of the servo motor.

[0006] Preferably, a winding flange is fitted on the outer side of the winding shaft, and a plurality of positioning pin holes are provided on the winding flange, with a conical positioning pin inserted into each of the positioning pin holes.

[0009] Preferably, the intermediate transmission sleeve is provided with a plurality of fastening bolts, which are arranged in a ring array.

[0010] Preferably, the side flange has a groove, and a sealing bushing is provided in the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Flexible height adaptation: The linkage structure between the electric push rod and the rotating arm allows the winding shaft to be freely adjusted in height within a certain range, adapting to the covering needs of materials and places of different heights and improving the fit of the tarpaulin. Precise and stable tarpaulin retraction: The servo motor, in conjunction with the electromagnetic brake, enables rapid start-stop and precise positioning of the tarpaulin retraction, preventing the tarpaulin from shifting due to inertia.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0017] Reference Figures 1-6 A tracked chassis folding arm tarpaulin covering device includes a tracked vehicle 4, which serves as the mobile carrier of the equipment, adapting to complex terrain and enabling the entire machine to be moved to the work area, such as open-air storage or construction sites, providing flexible position adjustment capabilities for tarpaulin covering operations. A frame 2 is fixedly installed on the tracked vehicle 4, and a support base 1 is fixedly installed on the frame 2. A first rotating shaft 16 and a second rotating shaft 15 are rotatably connected to the support base 1. A rotating arm 5 is fixedly connected to the first rotating shaft 16, and an electric push rod 3 is fixedly connected to the second rotating shaft 15. A third rotating shaft 10 is rotatably connected to the drive end of the electric push rod 3. The third rotating shaft 10 and the rotating arm 5 are fixedly connected. When the electric push rod 3 extends or retracts, it pushes the rotating arm 5 to rotate around the first rotating shaft 16, achieving precise adjustment of the height of the winding shaft 8, such as from the ground to the high-altitude work area, adapting to different covering height requirements.

[0018] refer to Figure 1 A support arm 6 is fixedly mounted on the rotating arm 5, and a servo motor 7 is fixedly mounted on the support arm 6. The drive end of the servo motor 7 is fixedly connected to the winding shaft 8, and the drive end of the servo motor 7 is equipped with an electromagnetic brake. The servo motor 7 serves as a power source to drive the winding shaft 8 to rotate in both directions, thereby realizing the winding and unwinding actions of the tarpaulin. At the same time, the drive end of the servo motor 7 is equipped with an electromagnetic brake, which can quickly brake after the tarpaulin is wound or unwound to prevent the tarpaulin from slipping due to inertia and ensure coverage accuracy.

[0019] refer to Figure 6A winding shaft 8 is fitted with a winding shaft flange 9 on its outer side. Multiple positioning pin holes 18 are provided on the winding shaft flange 9. A conical positioning pin is inserted into each positioning pin hole 18. After inserting the conical positioning pin, the connection stability between the winding shaft 8 and other transmission components can be enhanced, and the winding shaft can be prevented from slipping or shifting when the tarpaulin is retracted.

[0020] refer to Figure 6 A side flange 13 is fixedly mounted on the drive end of the servo motor 7. One end of the winding shaft 8 is inserted into the inside of the side flange 13. An intermediate transmission sleeve 11 is fitted on the outside of the side flange 13. The intermediate transmission sleeve 11 can be designed with an adjustable inner and outer diameter structure, such as a nested bushing, to adapt to different winding shafts 8 (φ50-φ200mm) and servo motor 7 shaft diameters (φ20-φ60mm), improving component versatility. Multiple radial positioning pins 14 are installed on the side flange 13, and the multiple radial positioning pins 14 are arranged in a ring array. Multiple fastening bolts 12 are provided on the intermediate transmission sleeve 11, arranged in a circular array. A groove is provided on the side flange 13, and a sealing bushing 17 is provided in the groove. The intermediate transmission sleeve 11 is fitted on the outside of the side flange 13, and the circumferential rotation of the intermediate transmission sleeve 11 is restricted by multiple radial positioning pins 14. The connection is further reinforced with the fastening bolts 12 to ensure reliable torque transmission. The fastening bolts 12 are 10.9 grade high-strength bolts, with spring washers and thread locking agents such as Loctite 271 to prevent the bolts from loosening due to equipment vibration. In addition, the sealing bushing 17 in the groove of the side flange 13 is compressed and filled in the gap between the side flange 13 and the winding shaft 8, which has the functions of buffering and anti-loosening. It can prevent mud, sand and rainwater from entering the transmission part, protect the internal components, and improve the durability of the equipment.

[0021] In this invention, the tracked vehicle 4 moves the equipment to the work area. Based on the height of the material to be covered, the coverage area of ​​the tarpaulin is planned, and the electric push rod 3 is controlled to extend or retract. If covering higher materials, the electric push rod 3 extends, pushing the rotating arm 5 to rotate upward around the first rotating shaft 16, causing the support arm 6 and the winding shaft 8 to rise. If covering lower materials, the electric push rod 3 retracts, pulling the rotating arm 5 to rotate downward, lowering the height of the winding shaft 8. During this process, the angle adjustment of the rotating arm 5 is achieved through the rotational cooperation of the first rotating shaft 16 and the third rotating shaft 10. The linear motion of the electric push rod 3 is converted into the rotational motion of the rotating arm 5, accurately adapting to the coverage height. The servo motor 7 is started to rotate forward. The drive end of the servo motor 7 drives the winding shaft 8 to rotate through the side flange 13, the intermediate transmission sleeve 11 and other components. The winding shaft 8 releases the tarpaulin, and the tarpaulin extends towards the area to be covered under its own weight and traction.

[0022] The electromagnetic brake is in the released state when the tarpaulin is not fully released. Once the tarpaulin is in place, the electromagnetic brake brakes quickly, locking the winding shaft 8 to prevent the tarpaulin from slipping and ensuring a good fit. When the tarpaulin needs to be retracted, the servo motor 7 reverses, and the winding shaft 8 rotates counterclockwise to retract the tarpaulin. The electromagnetic brake is released, and the tarpaulin winds orderly along the spiral groove of the winding shaft 8. After winding, the electromagnetic brake brakes again to fix the winding shaft 8, and the tarpaulin is neatly stored. If the tarpaulin covering angle needs to be adjusted, such as from covering one side of the material yard to covering the other side, the horizontal angle of the winding shaft 8 can be changed by controlling the slight extension and retraction of the electric push rod 3, in conjunction with the rotation of the rotating arm 5 around the first rotating shaft 16, thus achieving flexible adjustment of the tarpaulin covering direction. At the same time, the tracked vehicle 4 can assist in movement to expand the covering range and adapt to working areas of different shapes and positions. The winding shaft 8 can be flexibly adjusted and adapted according to the height to be covered by the tarpaulin. When covering materials or places that are higher or lower, the tarpaulin covering fit is higher, which is beneficial to the use of the tarpaulin winch.
