Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by the technical personnel in the field without creative work belong to the protection scope of the present invention.

As shown in fig. 1-5.

The utility model provides a pair of railway engineering vehicle railing door locking device, it includes first railing 1 and second railing 2, first railing 1 and second railing 2 are isometric, and the one end of first railing 1 and second railing 2 is connected jointly on the machineshop car, and the machineshop car is at the another side of fig. 1, and prior art no longer gives details, the utility model discloses an explain during as the actual equipment state shown in fig. 1 to be convenient for understand technical scheme, the tradition mounting means of door plant has been used, the utility model discloses in, as shown in fig. 1, the one end that first railing 1 kept away from the machineshop car is equipped with hinged-seat 3, has railing door 4 through hinged-seat 3 swing joint on first railing 1, and when railing door 4 closed, it sheltered from the afterbody (position in the picture) at first railing 1 and second railing 2, has constituted a rail formula parking space that is used for adorning and getting the goods with machineshop car position.

In the utility model, the closing mode of the balustrade door 4 is creatively designed, as shown in fig. 1 to 4, the balustrade door 4 is welded with the lock nose 5 far away from the other end where the hinged support 3 is installed, the hanging nose 6 corresponding to the lock nose 5 is welded at the end of the second balustrade 2 far away from the engineering vehicle, the lock nose 5 is provided with the U-shaped positioning slot 61 matching with the hanging nose 6, the second balustrade 2 is welded with two fixing plates 7 corresponding to the upper part of the hanging nose 6, the bottom ends of the two fixing plates 7 are penetrated with the cylindrical pin 8, the locking switch 9 for locking the position of the lock nose 5 clamped into the hanging nose 6 when the cylindrical pin 8 rotates downwards is arranged between the two fixing plates 7, namely, in the utility model, after the goods are loaded and taken, if the balustrade door 4 is to be closed rapidly, the operator only needs to rotate the balustrade door 4, and the end with the lock nose 5 rotates towards the direction of the second balustrade 2, finally, the lock nose 5 is buckled on the hanging nose 6 by the U-shaped positioning slot 61, when the hand rail door 4 is rotationally closed, because the impact force generated during the rotation is large, the lock nose 5 on the lock nose can firstly impact the pressure-bearing part 93 arranged at the outer edge of the bottom end of the lock switch 9, as shown in fig. 5, the pressure-bearing part 93 can force the limiting plate 91 on the lock switch 9 to rotate around the cylindrical pin 8 due to the impact, and when the limiting plate 91 is rotationally closed, the top end of the lock nose is far away from the second hand rail 2 and rotates towards the right (in the direction of the figure), the bending part 94 at the bottom end of the lock nose can rotate towards the direction of the second hand rail 2, and the action can be completed at the moment when the lock nose 5 impacts the pressure-bearing part 93, and the lock nose 5 is clamped on the outer wall surface of the second hand rail 2, and the U-shaped positioning slot 61 is clamped on the hanging nose 6, then under the action of gravity, and because the stop rod 10 corresponding to the upper part of the locking switch 9 is welded between the two fixing plates 7, after the limiting plate 91 completes the above-mentioned rotation action, the top end of the limiting plate is limited by the stop rod 10, and a reaction impact force is generated on the limiting plate, and the limiting plate 91 is forced to reversely rotate again until the bending part 94 at the bottom end of the limiting plate just falls back to block the locking nose 5, so that the balustrade door 4 is convenient to rapidly close, and an operator only needs to throw the balustrade door 4 with force to throw one end with the locking nose 5 onto the hanging nose 6 when closing. In conclusion, it can be seen that the closing process of the balustrade door 4 is convenient without manually operating other locking components.

As shown in fig. 2 to 5, a shifting piece 92 is disposed at the top end of the limiting plate 91, and a round rod 97 for making the shifting piece 92 far away from the outside of the second handrail 2 is welded between the shifting piece 92 and the locking switch 9, that is, the shifting piece 92 installed at the top end of the limiting plate 91 is located outside the second handrail 2, an operator manually rotates the shifting piece 92 to manually control the limiting plate 91 to rotate around the cylindrical pin 8 to a state shown in fig. 5, the pressure-bearing portion 93 at the bottom end of the limiting plate 91 passes through the lock nose 5 forcibly during the manual rotation process, and finally crosses over the lock nose 5, and the inclined surface portion of the lock nose is displayed near the lock nose 5, and at this time, the lock nose 5 is far away from the bent portion 94 to be bound, and the operator only needs to push the handrail 4 in the direction opposite to the rotation direction of closing the handrail 4, so as to open the handrail in a rotating manner.

As shown in fig. 3, the bottom end of the bearing portion 93 is provided with a first hanging hole 95, the top end of the hanging nose 6 is provided with a second hanging hole 62, and according to actual needs, a padlock in the prior art can pass through the first hanging hole 95 and the second hanging hole 62 in a closed state, so that the whole locking device is locked, and people and other people are prevented from getting on the vehicle.
