Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical design, and in particular relates to a fastener with a high load-to-weight ratio. Background Art

[0002] The transport fixture is an important part of ensuring the mobility of vehicle-mounted equipment. Its main function is to lock the equipment during transportation, maintain the stability of the rotating part of the equipment system, avoid rotation caused by bumps during driving, and avoid impact damage to other mechanisms.

[0003] As special vehicle carrying equipment continues to develop towards integration, transport fixtures are facing the development trend of automation, generalization, and high load-to-weight ratio. Although existing transport fixtures have the characteristics of simple structure and easy processing, their insufficient automation, poor adaptability, and low load-to-weight ratio are particularly obvious in the application of transport fixtures, which affects the transportation stability and rapid response ability.

[0004] The transport fixture, which is composed of a motor, a screw lift, a proximity switch, and a sensor, has become a viable alternative due to its significant advantages such as automation, high load-to-weight ratio, and good adaptability. However, the existing transport fixtures cannot meet the requirements of automation, quick disassembly, and generalization, which limits their application scope in vehicle-mounted rotary platforms. In order to adapt to the requirements of different load-bearing equipment, it is urgent to develop a universal, automated, quick-disassembly, and highly adaptable high load-to-weight ratio transport fixture to meet the growing demand for vehicle-mounted transportation.

It can be quickly disassembled, repaired and replaced, and has the advantages of high universality and good maintainability.

[0017] The utility model meets the automation requirements. A motor drives the screw elevator to lift the latch, so that the induction plate is located in the two proximity switches and moves up and down, and can automatically lock and unlock the rotating part. The utility model has manual and automatic control modes. Only when the electrical signal of the proximity switch is connected to the control system, the screw elevator is allowed to be powered on to execute the action. When the locking and unlocking are in place, the locking in place sensor indicator light and the unlocking in place sensor indicator light are on. A sensor is arranged on the transport fixture. When the transport fixture is not unlocked, the follow-up turning and tracking cannot be performed, and the safety is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0023] Example:

[0024] like Figures 1 to 3 As shown, a high load-to-weight ratio fixer includes a latch 2, a fixed support 6 and a spiral elevator 7. The latch 2 is connected to the elevator 7 through a pin shaft 4, and the latch 2 can be automatically or manually driven to move up and down. The latch 2 is set on the fixed support 6. When the latch 2 is locked, it is ensured that the latch and the pin hole are in contact. When unlocked, the latch 2 rises and the rotation center operates normally. A shield 8 is set on the elevator 7, and one side of the shield 8 is connected to the fixed support 6.

[0025] The fixing support 6 is provided with a connecting portion 13 , which is in a circular ring shape. The latch 2 is inserted into the connecting portion 13 for connection, and the latch 2 can move up and down in the connecting portion 13 .

[0026] The latch pin 2 is provided with a rubber dustproof seal ring 11 and a wear-resistant ring 12. The latch pin 2 is connected to the fixed support 6 via the dustproof seal ring 11 and the wear-resistant ring 12, and the reusability is improved.

[0027] A stud 1 and a screw hole 14 are provided on one side of the connection portion 13. The connection portion 13 is connected to the stud 1 through the screw hole 14. The stud 1 can resist the latch 2 to prevent the latch 2 from moving in a circumferential direction, that is, the latch 2 can only move up and down.

[0028] The fixing support 6 is provided with a mounting bracket 9, and the mounting bracket 9 is provided with a proximity switch 3. The fixing support 6 is connected to the rotating part of the vehicle body by bolts, which can not only match according to the relevant interface of the special vehicle, but also achieve the purpose of rapid disassembly and maintenance.

[0029] The latch 2 is provided with a sensing plate 5, which is provided on the side of the latch 2 close to the proximity switch 3. The sensing plate 5 is connected to the latch 2 by bolts and can move up and down with the latch 2. The sensing plate 5 can only be moved within the vertical distance between the two proximity switches 3. The upper proximity switch 3 is in the unlocking position of the transport fixture, and the lower proximity switch 3 is in the locking position of the transport fixture. When the electrical signal of the proximity switch 3 is connected to the control system, the screw elevator 7 is allowed to be powered on to perform the action.

[0030] The mounting bracket 9 is provided with a uni-shaped hole 15, and the proximity switch 3 is provided on the uni-shaped hole 15 by means of a bolt, and two proximity switches 3 and two uni-shaped holes 15 are provided, and are distributed on the upper and lower sides of the mounting bracket 9. Through the provision of the uni-shaped holes 15, the vertical distance between the two proximity switches 3 can be adjusted according to actual conditions, thereby increasing the adjustable range.

[0031] An adjustment pad 10 is arranged on the fixed support 6 .

[0032] The transport fixture of the utility model can automatically lock and unlock in less than 10 seconds, which greatly improves the rapid response capability of the equipment rotation. When locked and unlocked, the locked sensor indicator light and the unlocked sensor indicator light are on. A sensor is provided on the transport fixture. When the transport fixture is not unlocked, it cannot be turned and tracked, which is more secure.
