Description

Technical Field

[0001] This utility model relates to elevator manufacturing technology, and in particular to a counterweight frame with an inclined counterweight wheel. Background Technology

[0002] To meet the requirements of the civil engineering layout for machine room-less elevators, the existing technology adopts an inclined counterweight wheel arrangement. The elevator counterweight is usually approximately a cuboid structure. Taking the vertical plane with the length and width determined when the elevator counterweight is in use as the reference plane, the inclined counterweight wheel means that the axis of the counterweight wheel is not perpendicular to the reference plane, but has a non-zero angle (i.e., tilt angle) with the reference plane.

[0003] Existing counterweight rollers are generally installed in the upper beam, resulting in a relatively complex structure. Due to the limited space within the upper beam, installation is inconvenient for workers. Furthermore, the limited space restricts the tilting angle of the counterweight rollers, sometimes failing to achieve optimal results. Additionally, the existing counterweight blocks are installed as a single long strip, which is also inconvenient in the confined space of the shaft. Summary of the Invention

[0004] To solve the above problems, the technical solution of this utility model is: a counterweight frame with an inclined counterweight wheel, which consists of two symmetrical and identical vertical beams, a bottom beam fixedly connected to the bottom of the vertical beams, an upper beam fixedly connected to the top of the vertical beams, a middle vertical beam between the two vertical beams, and a counterweight block between the two vertical beams and the middle vertical beam; the upper beam is composed of two parallel steel plates, and a counterweight wheel assembly is inclinedly and fixedly installed on the upper beam; The counterweight wheel assembly includes two identical symmetrical upright plates. The bottom of the upright plates has a notch through which a steel plate passes. The bottom of the upright plates is fixedly connected by a ∩-shaped fixing plate. A horizontal plate is fixedly installed above the fixing plate on the bottom of the steel plate. The fixing plate is fixedly connected to the horizontal plate. The counterweight wheel is installed on the upright plates above the upper beam.

[0005] Furthermore, a ┌-shaped protective plate is fixedly installed on the top of the upright plate. The length of the protective plate is less than the diameter of the counterweight wheel, and its width is greater than the thickness of the counterweight wheel.

[0006] Furthermore, a middle beam is fixedly installed between the two upright beams, and the middle beam is also fixedly connected to the middle upright beam.

[0007] Furthermore, both the vertical beam and the central vertical beam are equipped with counterweight fixing plates.

[0008] Furthermore, a bumper assembly is fixedly installed at the bottom of the bottom beam.

[0009] Furthermore, the two uprights are also fixedly connected on both sides by a protective frame.

[0010] The beneficial effects of this utility model are: The counterweight rollers are mounted on the upright plate and connected to the upper beam through the upright plate, which allows for a greater adjustable angle of the counterweight rollers, making them suitable for various construction scenarios.

[0011] The counterweight wheel assembly is installed above the upper beam, making installation more convenient and easier for workers, thus effectively improving installation efficiency.

[0012] This application proposes to install the counterweight in two sections on the counterweight frame, which makes installation in confined spaces more convenient. The two sections also reduce the weight of each individual counterweight, making it easier for workers to handle and install. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] exist Figures 1 to 2 In this invention, a counterweight frame with inclined counterweight wheels is provided, comprising two symmetrical and identical vertical beams 3. A bottom beam 1 is fixedly connected to the bottom of the vertical beams 3, and an upper beam is fixedly connected to the top of the vertical beams 3. A middle vertical beam 10 is also provided between the two vertical beams 3 and the middle vertical beam 10. A counterweight block 2 is provided between the two vertical beams 3 and the middle vertical beam 10. The upper beam is composed of two parallel steel plates 5, and a counterweight wheel assembly is inclinedly and fixedly installed on the upper beam. The counterweight wheel assembly includes two identical symmetrical upright plates 6. The bottom of the upright plate 6 is provided with a notch, through which a steel plate 5 passes. The bottom of the upright plate 6 is fixedly connected by a U-shaped fixing plate 13. A horizontal plate 12 is fixedly installed above the fixing plate 13 at the bottom of the steel plate 5. The fixing plate 13 is fixedly connected to the horizontal plate 12. The counterweight wheel 8 is installed on the upright plate 6 above the upper beam.

[0018] Using the above technical solution, the counterweight roller 8 is fixed by passing through the notch of the upright plate 6 through the steel plate 5. This design allows for a wider range of angle adjustment for the counterweight roller 8. The counterweight roller assembly is installed above the upper beam, which is convenient for workers to install and also facilitates the adjustment of the angle of the counterweight roller 8.

[0019] As a further improvement of the utility model, a ┌-shaped protective plate 7 is fixedly installed on the top of the upright plate 6. The length of the protective plate 7 is less than the diameter of the counterweight wheel 8, and its width is greater than the thickness of the counterweight wheel 8.

[0020] By adopting the above technical solution, debris can be prevented from falling onto the counterweight roller 8, thus improving the safety of use.

[0021] As a further improvement to the utility model, a middle beam 4 is also fixedly installed between the two vertical beams 3, and the middle beam 4 is also fixedly connected to the middle vertical beam 10.

[0022] By adopting the above technical solution, a central beam 10 is set between the two upright beams 3, so that the counterweight 2 is installed on the counterweight frame in two sections. One is to reduce the weight of a single counterweight 2, and the other is to reduce the length of the counterweight 2, which is conducive to installing the counterweight 2 on the counterweight frame in a narrow space.

[0023] As a further improvement to the utility model, both the vertical beam 3 and the central vertical beam 10 are equipped with counterweight fixing plates 11.

[0024] By adopting the above technical solution, the counterweight 2 can be better limited and fixed, preventing it from generating noise during elevator operation.

[0025] As a further improvement of the utility model, a bumper assembly 14 is fixedly installed at the bottom of the bottom beam 1.

[0026] By adopting the above technical solution, in the event of a failure, the bottom beam 1 can be effectively prevented from directly impacting the bottom surface, thus effectively reducing the impact force.

[0027] As a further improvement to the utility model, the two upright plates 6 are also fixedly connected on both sides by a protective frame 9.

[0028] By adopting the above technical solution, better protection can be provided for the counterweight roller 8, and the safety of workers can be effectively guaranteed during maintenance.
