It is suitable for various high-end office buildings, star-rated hotels, convention and exhibition centers and other places.

[0003] Most machine room-less elevators on the market operate the elevator by installing two car bottom wheel seats under the lower beam of the car frame, which increases the production cost of the elevator and causes unnecessary waste. Summary of the invention

[0004] The object of the present invention is to provide a machine roomless elevator without a lower beam, so as to solve the problem that most of the machine roomless elevators on the market mentioned in the above background technology are to install two car bottom wheel seats under the lower beam of the car frame to run the elevator, which increases the production cost of the elevator and causes unnecessary waste.

[0005] The cam is provided with a plurality of holes, the holes being respectively provided with a first hole and a second hole, and a first hole being provided on the top of the cam, and a second hole being provided on the bottom of the cam.

[0006] Preferably, a third threaded hole corresponding to the fixing hole is formed on the side wall of the car, and the fixing hole and the third threaded hole are connected and fixed by screws.

[0007] Preferably, the vertical beam safety clamp is fixedly connected to the safety clamp installation groove by a second bolt.

[0008] Preferably, the lower guide shoe of the vertical beam is fixedly connected to the lower guide shoe mounting groove by a first bolt.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention has a simple structure, eliminates the traditional lower beam and car bottom wheel seat, eliminates the safety clamp and guide shoe installed on the car bottom wheel seat, uses the vertical beam safety clamp and the vertical beam lower guide shoe installed in the vertical beam of the car frame to correspond to the lower guide shoe mounting groove and the safety clamp mounting groove opened on the connecting plate, and fixes them with the first bolt and the second bolt, so that the car bottom wheel seat and the car are directly fixedly connected through the mounting plate, thereby reducing the production cost.

[0016] Example:

[0017] See also Figure 1-2The present invention provides a technical solution: a beamless and machine roomless elevator, comprising a car wheel base 1, a mounting plate 2 is fixedly arranged on the upper end of the car bottom wheel base 1, a plate wall of the mounting plate 2 is provided with symmetrical fixing holes 3, a connecting plate 5 is vertically fixedly arranged on the front end of the mounting plate 2, a lower guide shoe mounting groove 6 is provided on the front end of the connecting plate 5, a symmetrical first threaded hole 7 is provided on the inner wall of the lower guide shoe mounting groove 6, a vertical beam lower guide shoe 11 is fixedly arranged on the front end of the lower guide shoe mounting groove 6, a safety clamp mounting groove 8 is provided on the side wall of the connecting plate 5 and located on the upper side of the lower guide shoe mounting groove 6, and the safety clamp mounting groove 8 has a first threaded hole 7 on the inner wall of the lower guide shoe mounting groove 6. A symmetrical second threaded hole 9 is opened on the inner wall, and a vertical beam safety clamp 12 is fixedly arranged at the front end of the safety clamp installation groove 8. A car frame vertical beam 10 is fixedly arranged between the connecting plate 5 and the lower guide shoe 11 of the vertical beam and the vertical beam safety clamp 12. The vertical beam 10 of the car frame is fixedly connected to the connecting plate 5 through the lower guide shoe 11 of the vertical beam and the vertical beam safety clamp 12, and the guide shoe and safety clamp installed on the car bottom wheel seat 1 are cancelled. A car 13 is fixedly arranged on the side wall of the car frame vertical beam 10, and the mounting plate 2 is fixedly connected to the car 13. Through the connection between the mounting plate 2 and the car 13, the use of the lower beam connection is cancelled, and the stability of the installation is maintained.

[0018] Among them, the side wall of the car 13 is provided with a third threaded hole corresponding to the fixing hole 3, and the fixing hole 3 and the third threaded hole are connected and fixed by a screw 4.
