Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, be described in further detail detailed description of the invention of the present utility model, object helps those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme, and contribute to its enforcement.
As shown in Figure 1, this towing pin anti-drop device, tractive force, for connecting tractor truck and pulling material or locomotive, passes to and pulls material or locomotive by towing pin 6; Comprise traction seat 1, towing pin 6 is inserted on traction seat 1 in set mounting hole 7, and traction seat 1 is provided with the escapement with towing pin 6 adaptation; Effectively self-locking is carried out to towing pin 6 by escapement, prevent towing pin 6 from coming off, ensure that tractor truck is reliably connected smoothly with trailer.
As shown in Fig. 1, Fig. 4 to Fig. 7, escapement comprises the mount pad 12 be located on traction seat 1, mount pad 12 is provided with the fixed pin shaft 2 that set hold down groove 9 on towing pin 6 is inserted in one end, fixed pin shaft 2 other end is set with and compresses with mount pad 12 Compress Spring 3 contacted.Towing pin 6, by coordinating with the hold down groove 9 on towing pin 6, is fixed on traction seat 1 by fixed pin shaft 2; Fixed pin shaft 2, for pinning towing pin 6, prevents towing pin 6 from coming off.
Compress Spring 3 is resisted against between fixed pin shaft 2 and mount pad 12, prevents fixed pin shaft 2 from bouncing back and causes pinning disabler.Fixed pin shaft 2 inserts in hold down groove 9, under the power effect of Compress Spring 3, effectively carries out self-locking to fixed pin shaft 2, prevents fixed pin shaft 2 from deviating from the hold down groove 9 of towing pin 6, prevents towing pin 6 in tractor truck driving conditions from coming off.
Fixed pin shaft 2 is provided with and compresses with end, Compress Spring 3 one end the back-up ring 4 contacted, and on fixed pin shaft 2, back-up ring 4 side is provided with the locating dowel pin 5 of spacing back-up ring 4.The elastic force that back-up ring 4 produces for bearing, transmitting Compress Spring 3; Locating dowel pin 5 is used for limiting the position of back-up ring 4, the elastic force that back-up ring 4 bears is passed to fixed pin shaft 2 simultaneously.The structure of locating dowel pin 5 and back-up ring 4, not only simple structure, and easy accessibility.
Fixed pin shaft 2 is provided with the knock hole 8 coordinated with locating dowel pin 5; Locating dowel pin 5 inserts in knock hole 8, and what can realize back-up ring 4 is spacing, and then for limiting the position of Compress Spring 3.
Mount pad 12 is U-board, and the open end of mount pad 12 is provided with the fixed installation hole 10 of installing fixed pin shaft 2; U-shaped structural slab, not only convenient installation, and while guarantee structural reliability, comparatively save material, be beneficial to and reduce costs.
Fixed pin shaft 2 one end is inserted in hold down groove 9 through fixed installation hole 10 and hold down groove 9 coordinates, and fixed pin shaft 2 other end end is provided with the handle 13 of upwards bending.Handle 13 1 aspect can play position-limiting action, is convenient to the plug of fixed pin shaft 2 on the other hand, is convenient to the quick release of escapement.
Handle 13 is provided with annulus; Annulus facilitates the plug of fixed pin shaft 2.
Mount pad 12 bottom and traction seat 1 weld, and mount pad 12 installation reliability is good.
Towing pin 6 is bolted on tractor truck; Traction seat 1 is provided with bolt mounting holes, is fixed in the afterbody of tractor truck with bolt by bolt mounting holes, is used for the tractive force of transmitting tractive car; Again escapement being fixed thereon, for pinning towing pin 6, preventing from coming off.
This towing pin anti-drop device can make towing pin 6 be in two mode of operations:
As shown in Figure 2, towing pin 6 is in can insert the state of getting: with pulling out fixed pin shaft 2, Compress Spring 3 is shortened by compression, fixed pin shaft 2 to be turned right movement to direction as shown, departing from outside the hold down groove 9 of towing pin 6, now can get by pulling the draw ring 11 on towing pin 6 to realize freely inserting of towing pin 6.
As shown in Figure 3, towing pin 6 is in stationary state: unclamp fixed pin shaft 2 after towing pin 6 is inserted traction seat 1, now Compress Spring 3 is not applied in any power, carry out reply by compressive state to elongate, fixed pin shaft 2 is mobile with the elongation of Compress Spring 3, until fixed pin shaft 2 insert towing pin 6 hold down groove 9 in stop, now towing pin 6 is fixed on traction seat 1 cannot insert and gets.
This towing pin anti-drop device, adopt the method for axial restraint, be fixed on traction seat 1 by towing pin 6, vehicle is the used time not, and towing pin 6 is fixed on vehicle can not be lost, and also can not come off because vehicle traveling is jolted, towing pin 6 is reliably locked on traction seat 1.The present invention can be used for the fixing of all directions of towing pin 6, and can only place towing pin 6 by vertical direction relative to original, after adopting the present invention, the installation of towing pin 6 is more flexible.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; Or without improvement, above-mentioned design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model.
