Embodiment one: as shown in fig. 1 and 2, the safety protection device for a high-speed sightseeing elevator only comprises a car body 2 and a protection part 1 arranged on the upper side of the car body 2, wherein the protection part 1 comprises a first plate 11 and a second plate 12 arranged on one side of the first plate 11 close to the car body 2, a through hole 121 is formed in the second plate 12, two groups of scissor structures 21 with mutually hinged scissor structures are arranged on one side of the car body 2 close to the first plate 11, one end of the scissor structures 21 away from the car body 2 is connected with the first plate 11 through a first spring 13, at least one part of the first spring 13 is positioned in the through hole 121, the second plate 12 is connected with the car body 2 through a second spring 14, and a third spring 22 is connected between two adjacent hinging points of the scissor structures 21.

In the utility model, the car body 2 is an elevator passenger freight car, the protection part 2 is arranged on the upper side of the car body 2, the body of the protection part 1 is a first plate 11, a second plate 12 is fixedly arranged on the lower side of the first plate 11, the first plate 11 and the second plate 12 are respectively connected with the car body 2 through a first spring 13 and a second spring 14, but the first plate 11 is connected with a scissor structure 21 arranged on the upper side of the car body 2 through at least a part of the first spring 13 positioned in the through hole 121, and a third spring 22 is connected between two adjacent hinge points in the scissor structure 21.

Here, each group of scissors structures 21 is provided with a plurality of connecting plates hinged end to end, a hinge point hinged with the other group of scissors structures is arranged in the middle of each connecting plate, and when two adjacent hinge points are close, the scissors structures 21 are shortened; conversely, when two adjacent hinge points are far away, the scissor-fork structure 21 stretches; one end (lower end) of the scissor fork structure 21 is connected to the car body 2, and the other end (upper end) of the scissor fork structure 21 is connected to the first plate 11 by the first spring 13.

The primary length of the first spring 21 is smaller than the depth of the through hole 121 when it is not affected by an external force, that is, the scissor structure 21 is partially disposed in the through hole 121 when it is not affected by an external force.

Under tension of the third spring 22, adjacent two hinge points are close, the scissor structure 21 is shortened, and simultaneously the width of the scissor structure 21 is increased until the scissor structure abuts against the inner side wall of the through hole 121.

It is also noted that the utility model also comprises hoisting ropes comprising a main hoisting rope for connection to the upper end of the car body 2 and a secondary hoisting rope for connection above the first plate 11. Also, the length of the main hoisting ropes is greater than the length of the auxiliary hoisting ropes and the difference between them is greater than the thickness of the second plate 12. Here, when the main traction rope is straightened, the auxiliary traction rope is in a loose state; in general, the main traction rope drives the car body 2 to move up and down, and the protection part 1 simultaneously moves up and down under the support of the first spring 13 and the second spring 14; when the main rope is deactivated, the auxiliary rope plays a role in traction, and at this time, the auxiliary rope drives the protection unit 1 to move up and down, and the car body 2 moves up and down simultaneously by pulling down of the first spring 13 and the second spring 14.

Then, if the elevator is in operation, the protection part 1 can buffer the upper side of the car body 2, mainly the buffer function of the second spring 14, and the first spring 13 can also play a proper buffer function.

When the elevator loses upward pulling force to generate sudden drop, namely the main traction rope is out of action, the auxiliary traction rope plays a traction role at the moment, and the danger generated by sudden drop of the car main body 2 is effectively prevented.

Moreover, when the auxiliary traction rope plays a traction role, the first spring 13 and the second spring 14 can be pulled to be very open due to the fact that the mass of the car main body 2 is large, the length of the first spring 13 in the stretched state is larger than the depth of the through hole 121, the scissor-fork structure 21 is completely located outside the through hole 121, and the scissor-fork structure 21 can assist in hanging the car main body 2 under the pulling force of the third spring 22, so that the car main body 2 is further guaranteed not to fall suddenly.

Preferably, an electronic connecting buckle is arranged at the joint of the main traction rope and the car main body 2, and when the descending speed of the car main body 2 exceeds a preset threshold value, the electronic connecting buckle is released, so that the main traction rope is actively disabled, and the auxiliary traction rope performs traction work.

When the car body 2 is a sightseeing elevator car, the car body 2 is provided with a car door, and three sides are light transmitting members (glass members or similar transparent members), so that the protection part 1 is provided on the upper side of the car body 2, and three sides are not shielded from light transmission, thereby not affecting the sightseeing.

Finally, the width of the first plate 11 is greater than the width of the car body 2, so that the first plate 11 can slide in the hoistway, thereby restricting the sway of the car body 2.

In a word, this device both can carry out towards the protection of top, urgent weigh down protection and not shading outside, can also carry out certain guide and slide and reduce rocking, very be fit for high-speed sightseeing elevator and use.

The high-speed sightseeing elevator safety protection device has a simple structure, can effectively prevent the upper punch top and the falling of the elevator car, can simultaneously conduct sliding of the elevator car to reduce running shake, does not influence the transparency of the sightseeing side of the elevator, and can be effectively adapted to the sightseeing elevator.

The limit wing plate 23 and the limit hook plate 112 are actually a final safety, and when the auxiliary traction rope has the effect that if the total mass of the car main body 2 is too large, the first spring 13, the second spring 14 and the third spring 15 are prolonged too much, the lower side of the limit wing plate 23 is hooked by the limit hook plate 112 to be rigidly supported, and the car main body 2 is finally suspended; secondly, the running posture of the car body 2 can be stabilized due to the rigid suspension, so that the car body is prevented from shaking; third, the maximum extension length of the first spring 13, the second spring 14 and the third spring 15 is limited, and elastic fatigue is prevented.

Here, a slide guide 113 for matching with a slide rail in the hoistway is provided on a side of the sagging plate 111 away from the car body 2, the slide guide 113 slides in the hoistway, the limit hook plate 112 abuts against a side wall of the car body 2, and further the car body 2 is guided to slide to reduce shake.

Of course, the limiting wing plate 23 is arranged at the top end of the joint of two adjacent side walls of the car body 2, and the joint of two adjacent side walls of the car body 2 is certainly provided with a supporting column although the joint is a light-transmitting member, so that the limiting wing plate 23 is arranged on the supporting column, the final hanging supporting force is ensured not to act on the light-transmitting member, and the protection safety is improved.

It should be noted that when the main hoisting rope is in operation, due to the tension of the third spring 22, the two sides of the scissor-fork structure 21 are propped against the inner side of the through hole 121 and cannot be deformed, at this time, the scissor-fork structure 21 can be understood as a rigid member, so that the hinge is effectively ensured not to be worn due to frequent movement, and only when the first spring 21 is extended to a length greater than the depth of the through hole 121, the scissor-fork structure 21 starts to hinge.

Here, the scissor fork structure 21 is connected to the car body 2 via a connecting post 211. And the length of the connecting post 211 is not less than the original length of the second spring 14, that is, when the main hauling rope acts, the second spring 14 is almost in a natural state under a small external force (only the gravity of the protecting part 1 itself), at this time, under the extending length of the connecting post 211, it is ensured that the whole scissor structure 21 is located all inside the through hole 121, and the whole structure will not hinge.

In addition, the second plate 12 is a honeycomb steel plate, so that the self weight of the protection part 1 can be effectively reduced, and the first spring 13 and the second spring 14 can not be subjected to too large extrusion force at ordinary times (when the main traction rope works).

Further, the first plate 11, the sagging plate 111 and the limiting hook plate 112 are integrally formed, and the integrally formed structure has high strength and is convenient to install.

Finally, the side wall of the through hole 121 near one end of the car body 2 is arc-shaped, so that after the emergency is relieved, the main traction rope is re-started, and the scissor fork structure 21 is conveniently retracted into the through hole 121.

The present utility model is not limited to the above-described specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. of the above embodiments according to the technical substance of the present utility model should be included in the protection scope of the present utility model.
