Description

Technical Field

[0001] This utility model belongs to the field of maintenance vehicle technology, specifically referring to a maintenance vehicle used for the maintenance of information engineering lines. Background Technology

[0002] In the field of information engineering line maintenance, with the continuous development and upgrading of communication networks, the range of line laying is becoming increasingly wide, and the maintenance scenarios are becoming increasingly complex and diverse. Existing large maintenance vehicles face many limitations when operating in narrow spaces such as narrow streets, underground equipment rooms, and residential areas due to their large size and poor maneuverability. These limitations include difficulty in entering the work area, inconvenient operation due to excessive turning radius, and inability to get close to the maintenance point, which greatly reduces maintenance efficiency and may even delay emergency repairs due to the inability to reach the designated location.

[0003] Meanwhile, information engineering line maintenance requires the use of various types of cables, such as fiber optic cables, coaxial cables, and twisted-pair cables. However, current maintenance vehicles lack a systematic cable management and storage design. Cables are usually piled up randomly inside the vehicle or temporarily hung outside. When maintenance personnel need to use the cables, they are easily tangled, affecting the normal progress of maintenance work. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a maintenance vehicle for information engineering line maintenance, which effectively solves the problems of not being able to adapt to small space operations and effectively managing cables.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a maintenance vehicle for information engineering line maintenance, including a vehicle platform, a movable wheel provided at the bottom of the vehicle platform, a traction connecting frame fixedly connected to the vehicle platform, adjustable carrier plates provided on both sides of the vehicle platform, a unwinding mechanism provided at the center of the adjustable carrier plate and the vehicle platform, a drive structure connected to the adjustable carrier plate and a maintenance equipment toolbox provided on the vehicle platform in front of the unwinding mechanism;

[0006] The drive structure includes a groove, which is embedded in the side walls of the vehicle panel. A rotating shaft fixed to an adjustable carrier plate is rotatably mounted on the inner wall of the groove. A worm gear is fixed on the rotating shaft. A receiving cavity with openings on both sides is opened on the vehicle panel. A motor is installed on the outer wall of the vehicle panel. The output end of the motor is connected to a worm that passes through the receiving cavity and meshes with the worm gear.

[0007] Preferably, each set of unwinding mechanisms includes a movable support plate and a fixed support plate. The movable support plate is slidably mounted on an adjustable carrier plate and a carriage plate, respectively. The fixed support plate is fixed on the movable support plate, which is fixed on the adjustable carrier plate and the carriage plate. Both the movable and fixed support plates are rotatably mounted on a connecting shaft. A winding drum is sleeved on the connecting shaft. An abutment plate is also fixed on the connecting shaft, abutting against one side of the winding drum to limit its movement. The winding drum is used to wind cables. A threaded rod that is threadedly connected to the movable support plate is rotatably mounted on the fixed support plate. A handwheel is fixed at one end of the threaded rod.

[0008] Preferably, a limit block is fixed on the side of the take-up drum on the adjustable carrier plate and the vehicle plate, and the limit block is provided with a limit hole.

[0009] Preferably, the toolbox for maintenance equipment is provided with a cross-shaped partition, which divides the interior of the box into four independent storage spaces. A horizontal threaded post is fixed on the side wall of the partition, and a threaded sleeve is threaded onto the threaded post. The surface of the threaded sleeve is coated with an anti-slip layer, and a fastening block is fixed to one end of the threaded sleeve. An elastic rubber pad is attached to the surface of the fastening block.

[0010] Preferably, the maintenance equipment toolbox is a rectangular box with double doors.

[0011] Preferably, a battery box is fixed to the bottom of the vehicle platform, and a charging port protective cover is provided on the battery box.

[0012] The beneficial effects achieved by adopting the above-described structure are as follows:

[0013] 1. Through optimized design, this maintenance vehicle is more suitable for operation in small spaces in terms of structure and layout compared to traditional large maintenance vehicles. The traction connecting frame set at the front of the vehicle can be used with a small tractor to facilitate access to narrow alleys, underground spaces and other areas. The unwinding mechanism and maintenance equipment toolbox are reasonably arranged to reduce the overall space occupied by the vehicle, improve the mobility and operational flexibility in small spaces, and effectively solve the problems of traditional large maintenance vehicles when operating in small spaces.

[0014] 2. Three sets of unwinding mechanisms are installed, enabling independent winding of different types of cables, avoiding tangling and mixing. During use, the unwinding mechanisms on both sides can be flexibly adjusted from a vertical to a horizontal position, facilitating quick access to the required cables by maintenance personnel. The adjustable carrier plate is rotated via a drive structure, allowing the position of the unwinding mechanism to be adjusted according to working space and angle requirements, further enhancing cable retrieval convenience, significantly improving maintenance efficiency, and reducing the risk of cable damage.

A receiving cavity 24 with openings on both sides is opened on the carriage 1. A motor 25 is installed on the outer side wall of the carriage 1. The output end of the motor 25 is connected to a worm 28 that passes through the receiving cavity 24 and meshes with the worm gear 23. The motor 25 drives the worm 28 to rotate, which in turn drives the worm gear 23 and the rotating shaft 22 to rotate. The rotating shaft 22 drives the adjustable carrier plate 4 to rotate, which in turn drives the unwinding mechanism 5 to rotate, thereby adjusting the position and angle.

[0026] like Figure 1 , 2As shown in Figure 4, each unwinding mechanism 5 includes a movable support plate 6 and a fixed support plate 7. The movable support plate 6 is slidably mounted on the adjustable carrier plate 4 and the carriage plate 1, respectively.

[0029] In practical use, when it is necessary to inspect and repair information engineering lines, the repair vehicle is towed to the repair location by the traction connecting frame 3. According to the repair needs, the motor 25 of the drive structure 27 is started. The motor 25 drives the worm gear 28 to rotate. The worm gear 28 drives the worm wheel 23 and the rotating shaft 22 to rotate. The rotating shaft 22 drives the adjustable carrier plate 4 to rotate, adjusting the unwinding mechanism 5 from the vertical state to the horizontal state for easy access to the cable. As needed, the cable can be pulled out and passed through the limiting hole 14 for use.

[0030] Rotate the threaded sleeve 17 to move the fastening block 18 away from the maintenance equipment, take out the corresponding maintenance equipment from the maintenance equipment toolbox 26, after completing the maintenance work, start the motor 25, adjust the unwinding mechanism 5 back to the vertical state and then turn off the motor 25, put the maintenance equipment back in place, and pull the maintenance vehicle back to the storage location through the traction connecting frame 3.
