Detailed Description

The following describes a specific embodiment of the present embodiment with reference to the drawings.

Fig. 1 is an assembly diagram of the present invention. As shown in the combined figure 1, the utility model discloses a hidden elevator diagonal draw bar mechanism. The direction of X in the figure is the upper end of the assembly diagram of the utility model. The direction of Y in the figure is the right end of the assembly schematic of the utility model. The hidden elevator diagonal draw bar mechanisms are symmetrically arranged at two ends of the elevator lower beam. The hidden elevator diagonal draw bar mechanism comprises a lower beam pull lug 1, a pull rod 2 and a bridge bottom pull lug 3. The lower beam pull lug 1 is arranged on the lower beam of the elevator. The bridge bottom pulling lug 3 is arranged on the bridge bottom of the elevator far away from the lower beam of the elevator. Two ends of the pull rod 2 are respectively connected with a lower beam pull lug 1 and a bridge bottom pull lug 3.

The elevator lower beam is arranged at the bottom of the elevator bridge bottom. The hidden elevator diagonal draw bar mechanisms are symmetrically arranged at the left end and the right end of the elevator lower beam. The hidden elevator diagonal draw bar mechanism stabilizes the bridge bottom from the two ends of the elevator underbeam, so that the stress of the bridge bottom is balanced, and the stability of the elevator operation is ensured.

The lower beam pull lug 1 is installed on the lower beam of the elevator through a first bolt 4. The lower beam pull lug 1 is L-shaped.

A first through hole is formed in one end, close to the elevator lower beam, of the lower beam pull lug 1. The first bolt 4 passes through the first through hole to fixedly install the lower beam pull lug 1 on the lower beam of the elevator. And a second through hole is formed in one end, away from the elevator lower beam, of the lower beam pull lug 1.

Compared with the traditional scheme, the pull lug is not required to be arranged on the side beam of the elevator. The elevator side beam is a stress beam, and the inclined pull rod mechanism is arranged on the elevator side beam and can increase the stress of the elevator side beam. When the diagonal draw bar mechanism is installed, holes need to be formed in the side beam of the elevator, and the rigidity of the side beam of the elevator can be reduced.

The hidden elevator diagonal draw bar mechanism is arranged at the position of the elevator lower beam, so that the stress of the elevator side beam cannot be increased, and the rigidity of the elevator side beam cannot be reduced. On the premise of not influencing the original structure of the elevator, the stability of the operation of the elevator is ensured.

The pull rod 2 consists of a connecting plate 5 and a connecting rod 6 which are connected. The connecting plate 5 is connected with the lower beam pull lug 1 through a second bolt 7. The connecting rod 6 is connected with the bridge bottom pull lug 3 through a first nut 8.

One end of the connecting plate 5, which is far away from the lower beam pull lug 1, is connected with a connecting rod 6. One end of the connecting rod 6, which is far away from the bridge bottom pull lug 3, is connected with the connecting plate 5. And a third through hole is formed at one end of the connecting plate 5 close to the lower beam pull lug 1. The outer surface of the connecting rod 6 is processed with external threads.

And a second bolt 7 respectively penetrates through the third through hole and the second through hole to fixedly connect the connecting plate 5 with the lower beam pull lug 1. First nut 8 sets up on connecting rod 6, and connecting rod 6 adopts screw-thread fit with first nut 8.

Fig. 1 is an assembly diagram of the present invention. Fig. 2 is a schematic structural view of the bridge bottom pull lug of the present invention. Referring to fig. 1 and 2, the bridge bottom pull lug 3 is composed of a pull lug block 9 and a pull lug bolt 10 which are connected with each other. The lug pulling block 9 is provided with a lug pulling block through hole 11.

The bridge bottom pull lug 3 is installed on the bridge bottom of the elevator through a pull lug bolt 10. The pull rod 2 passes through the pull lug block through hole 11 and is fixed on the pull rod 2 through the first nut 8.

Preferably, the lug block 9 is square. The lug pulling bolt 10 is screwed into the bridge bottom of the elevator, and the bridge bottom pulling lug 3 is fixed on the bridge bottom of the elevator. The connecting rod 6 passes through the pull lug through hole 11. The first nuts 8 fix the connecting rod 6 from both ends of the pull lug block through hole 11.

The pull rod 2 is connected with the lower beam pull lug 1 through bolts, so that the connection stability is ensured. The pull rod 2 and the bridge bottom pull lug 3 are connected by double nuts and fixed from two ends, so that the pull rod 2 can stably support the bridge bottom of the elevator.

The installation length of the pull rod 2 can be lengthened or shortened according to the construction requirement. The pull rod 2 adopts a thickened design, so that the strength of the pull rod 2 is ensured.

The hidden elevator diagonal draw bar mechanism is fixed at the front end and the rear end of the elevator bridge bottom. Because the hidden elevator diagonal draw bar mechanism is designed symmetrically, the hidden elevator diagonal draw bar mechanism respectively fixes the front and back ends at the left side of the elevator bridge bottom and the front and back ends at the right side of the elevator bridge bottom.

Hidden elevator diagonal draw bar mechanisms are typically installed for use on glass hoistways or sightseeing elevators. Such elevators have special requirements for aesthetic appearance when installed. The effect that hidden elevator diagonal draw bar mechanism can not be seen from the elevator is achieved. Meanwhile, the elevator is not arranged on the side beam of the elevator, the operation of the elevator is more stable, the hidden type elevator diagonal draw bar mechanism supports the bottom of the elevator car from the stretching of the two ends of the lower beam of the elevator, the balanced stress of the bottom of the elevator car is guaranteed, and the comfort of the elevator is not influenced.

In the present embodiment, the lug piece 9 is described as being square, but the shape is not limited to this, and may be other shapes within a range capable of functioning.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
