Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to an H-type elevator gantry. Background Art

[0002] The H-type elevator gantry is an important part of the elevator. It is usually made of steel and has the function of bearing and supporting the elevator car. It can withstand various forces and vibrations generated during the operation of the elevator to ensure the stability and safety of the elevator. In addition, the design of the H-type elevator gantry can also improve the load-bearing capacity and operating efficiency of the elevator, allowing the elevator to operate more efficiently and safely.

[0003] In the prior art, the gantry includes a vertical frame, a horizontal top frame and a car bottom beam. The elevator car is installed between the two vertical frames and the car bottom beam. The outer side of the vertical frame is used to install safety clamps, guide shoes and other mechanisms. A sheave is installed on the upper part of the elevator car. The sheave is used to connect the steel rope and cooperate with auxiliary motors such as traction wheels and anti-ropes to realize the lifting and lowering operation of the elevator car. However, the sheave is generally installed on the gantry (i.e., the top of the horizontal top frame) and has a certain distance from the top of the elevator car. In this way, the overall height of the car is increased, and the applicability to low-rise buildings such as villas is relatively low, so further improvement is needed. Utility Model Content

[0043] Embodiment 2:

[0044] The embodiment of the present application discloses an H-type elevator gantry.

[0045] Reference Figure 4 The difference between the H-type elevator gantry disclosed in the embodiment of the present application and the embodiment 1 is that:

[0046] In this embodiment, a rotating rod 48 is rotatably installed on the top wall of the first shielding strip 44, and the rotating rod 48 is vertically arranged. The rotating rod 48 is provided with a rotating bar 6, and one end of the rotating bar 6 is fixedly connected to the outer peripheral wall of the rotating rod 48. The rotating bar 6 is rotatably installed on the first shielding strip 44 through the rotating rod 48; the rotating bar 6 is provided with an anti-slip component 7, and the anti-slip component 7 is used to dock with the mounting bolt 51 to limit the free rotation of the mounting bolt 51.

The limiting groove 721 is used for matching and inserting the mounting bolt 51. The anti-slip block 72 normally moves downward under the action of its own gravity and is sleeved on the mounting bolt 51 through the limiting groove 721.

[0048] The implementation principle of Example 2 of the present application is as follows: after the mounting frame 4 is installed on the horizontal top frame 1, the rotating bar 6 is rotated to rotate the anti-slip block 72 to the top of the mounting bolt 51, and the anti-slip block 72 moves downward under the action of its own gravity so that the mounting bolt 51 is inserted into the limiting groove 721 of the anti-slip block 72. The inner wall of the limiting groove 721 limits the mounting bolt 51, thereby limiting the free rotation of the mounting bolt 51 and keeping the mounting bolt 51 in a locked state, thereby improving the stability of the connection between the mounting frame 4 and the horizontal top frame 1 and improving the safety of the overall structure.

[0049] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
