Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment and workshop production technology, and specifically relates to a quick connection device for armored vehicle tracks. Background Technology

[0002] Track connection is a crucial step in armored vehicle production. Currently, track connection typically involves the vehicle starting up and the drive wheel rotating to move the track ends forward towards the hull. This requires steel cables to pull the track ends, and then the connection fixture is attached to the track plate end, with workers tightening it manually. However, vehicle startup generates a large amount of exhaust fumes that pollute the workshop environment. The fixture is a heavy component, and the steel cables are usually thick and large, making storage, handling, and installation time-consuming and labor-intensive, thus lengthening the production cycle. Loosening of the fixture to the track plate, or the track plate to the steel cables, can also pose safety hazards.

[0003] It can be seen that the traditional track connection method has the following drawbacks:

[0004] 1. The overhead crane cannot achieve precise position adjustment by suspending and pulling the track plates with steel wire ropes. It basically requires several ground personnel to manually assist in the positioning, often requiring 4 to 5 people to participate.

[0005] 2. Track connection fixtures are often designed to be bulky, and the traction wire ropes are usually quite thick. The storage, transportation, and installation of the fixtures and wire ropes all require a lot of manpower.

[0006] 3. To reduce the operating torque, long-handled tools are often used to pry and support the track plates to tighten them. At the same time, workers need to manually lift the track plates, which is laborious and dangerous.

[0007] 4. If the wire rope scrapes against the drive wheel, idler wheel, or vehicle body, the surface paint layer will be damaged.

[0008] 5. Vehicles produce exhaust fumes that pollute the environment and pose a danger when started. Utility Model Content

[0041] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0042] To overcome the shortcomings of bulky track connection fixtures, difficult track traction and alignment operations requiring multiple personnel, potential damage to the paint layer of the vehicle body, idler wheel, and drive wheel during operation, and exhaust pollution of the workshop environment caused by vehicle startup, this utility model designs a multi-degree-of-freedom movable track end-connection device. By using a fixed track traction device to pull the track around the vehicle's drive wheel, track support wheel, and idler wheel, the end of the track to be connected is positioned between the idler wheel and the first set of road wheels. Then, by adjusting the position of the track end-connection device hook, the track plates are tightened and connected.

[0043] The implementation of the armored vehicle track quick-connect device is shown in Figure 1. The track quick-connect device consists of a track end-connecting device 101 and a fixed track traction device 102. The fixed track traction device 102 completes the track traction around the vehicle wheel set, and the track end-connecting device 101 completes the docking and tensioning of the track plate ends.

[0044] I. Track end coupling device

[0046] The end-connection assembly 8 consists of a slide rail seat 15, a telescopic slider 16, a track plate hook 17, and a first lug seat 18, as follows: Figure 3 As shown. The slide rail seat 15 is mounted and suspended on the end of the swing arm 9 via the first ear seat 18, and can be adjusted for pitch along the first ear seat 18. The slide rail seat 15 has a slide rail groove and a base machined inside. The telescopic hydraulic cylinder 7 is installed on the base inside the slide rail seat 15, and the telescopic slider 16 is installed on the slide rail groove inside the slide rail seat 15. The piston rod of the telescopic hydraulic cylinder 7 is connected to the tail of the telescopic slider 16, which can drive the telescopic slider 16 to move along the slide rail seat 15. Two sets of track plate hooks 17 are installed at the ends of both the slide rail seat 15 and the telescopic slider 16. The lateral spacing of each set of track plate hooks 17 matches the size of the track plate. After adjusting the track end coupling device so that the track plate hooks 17 hook onto the end of the track plate, the track end coupling device is tightened and aligned under the action of the telescopic hydraulic cylinder 7, with a maximum tightening force of 5 tons. The overall telescopic stroke of the track end coupling device is 610mm. Figure 4 As shown.

[0047] The welded base of the fixed frame 11 is bolted to the forks of the pallet truck 6, and its upper end is connected to the rocker arm 9 via the second lug 19. The lifting hydraulic cylinder 10 is connected to the fixed frame 11 and the rocker arm 9 via the third lug 20 and the fourth lug 21. The movement of the lifting hydraulic cylinder 10 can drive the rocker arm 9 and the end-connecting assembly 8 to lift as a whole, with a stroke of up to 1000mm. Figure 4 As shown.

[0048] The end-connecting assembly 8 and the swing arm 9 are connected at a single point. During use, the end-connecting assembly 8 can be manually swung up and down along the first lug 18. By adjusting the positions of the telescopic hydraulic cylinder 7 and the lifting hydraulic cylinder 10, the track plate hook 17 can be easily moved to the end position of the track plate. Figure 5 As shown. When the two sets of track plate hooks 17 hook the ends of the track plates, keep the lifting hydraulic cylinder 10 stationary, tighten the telescopic hydraulic cylinder 7 to tighten and align the track plates, insert the track pin to complete the track connection, and then move the track end connecting device to the other side of the vehicle to connect the other track.

[0049] The control box 12 is fixedly installed on the forks of the transport vehicle 6. An opening is made on the back near the fixed frame 11.

Raise button 23 and lower button 24 control the lifting hydraulic cylinder 11, while tension button 25 and release button 26 control the telescopic hydraulic cylinder 7. Emergency stop button 27, when pressed in case of operational malfunction or emergency, can cut off power to prevent equipment damage or personnel danger.

[0051] II. Fixed Track Traction Device

[0052] The fixed track traction device 102 consists of an electrical control module 28 (the electrical control module is existing technology), a drive motor 29, a winch 30, a wire rope and traction hook 31, a safety guardrail 32, an H-beam welded base 33, a ground steel plate 34, and a fixed fixture 35, as shown in the schematic diagram. Figure 7 As shown.

[0053] The ground steel plate 34 serves as the operating area for track laying, vehicle placement, and track connection. Two sets of fixing fixtures 35 are installed on the ground steel plate 34 near the winch 30. The H-beam welded base 33 serves as the mounting base for other equipment and modules, and is installed on the ground using anchor bolts. The electrical control module 28 is installed on the side of the H-beam welded base 33 away from the vehicle. The drive motor 29 and the winch 30 are symmetrically distributed and installed on the side of the H-beam welded base 33 near the vehicle, with the centerline of the winch 30 aligned with the centerline of the fixing fixtures 35. The wire rope and traction hook 31 are wound around the drum of the winch 30 and are wound and unwound by the rotation of the winch 30. The safety guardrail 32 surrounds and fixes the track traction device 102 to prevent the wire rope from suddenly breaking and flying away, which could cause danger.

[0054] The method of using the track quick-connect device is as follows: First, hoist the two tracks onto the ground steel plate 34, unfold the tracks, and install one end of the tracks onto the fixed fixture 35. The overhead crane then lifts the chassis and places it onto the unfolded tracks, away from the fixed track traction device 102. Using the remote control, control the drive motor 29 to reverse the winch 30, releasing the two sets of wire ropes and hooks 31 until they extend to the rear of the vehicle and hook onto the ends of the two tracks. Control the winch 30 to reverse, and the wire ropes and traction hooks 31 pull the two track ends sequentially around the vehicle's drive wheel, track support wheel, and idler wheel. Loosen the two sets of track ends on the fixed fixture 35, move the track end-connecting device 101 to the front side of the vehicle, and manually attach the loosened track ends to the track plate hook 17 on the outside of the end-connecting assembly 8. Then, detach the wire rope and towing hook 31 from the track, manually put the track head onto the track plate hook 17 on the outside of the end coupling assembly 8, tighten and align the track head and tail through the track end coupling device 101, and then insert the track pin to complete the assembly. Then move the track end coupling device 101 to the other side of the front of the vehicle and repeat the operation to complete the track assembly on that side.

[0055] It can be seen that this utility model has the following characteristics:

[0056] 1. The designed fixed track traction device provides power for track traction, avoiding air pollution and safety risks caused by starting vehicles within the workshop. The wire rope and tow hook are mechanically deployed and retracted, saving operating space and overhead crane time, and reducing labor intensity. The fixed track traction device uses a mechanized method for deploying and retracting the wire rope and tow hook, avoiding the need for starting vehicles within the workshop. It has two modes: single-sided operation and simultaneous double-sided operation, which can be switched according to production needs.

[0057] 2. The designed track end-connector integrates the functions of traditional tooling and fixtures into a single device. Mounted on a transport vehicle, this device improves equipment handling efficiency. Two sets of hydraulic cylinders adjust the height and extension of the end-connector assembly, while the pitch angle of the assembly relative to the rocker arm can be manually adjusted. This allows for rapid alignment and engagement of the hook with the track plate end, reducing labor intensity and increasing track connection assembly production efficiency. The spatial position adjustment of the end-connector assembly is flexible and convenient, and a single unit can meet the alignment and engagement requirements of the track ends.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
