Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, and in particular relates to a split car top structure for a heavy-duty elevator. Background Technology

[0002] With the development of high-rise buildings and large commercial facilities, the demand for high-capacity elevators is increasing. High-capacity elevators typically require larger car space, and correspondingly, the car top dimensions also increase.

[0003] Traditional large-size integrated car roof structures have problems such as transportation difficulties, inconvenience in entering the shaft, and limited installation space, which are particularly prominent when the top floor of the shaft is not high enough.

[0004] Existing car roof structures typically install ventilation devices (fans) and lighting devices (lamp fixtures) as separate components on top of the car roof frame or ceiling panel, which increases the structural height, number of parts, and installation complexity.

[0005] The car top and the straight beam inside the hoistway are usually directly fixed to the car top frame with bolts. For heavy-duty elevators, the installation accuracy and stability requirements are higher. Traditional installation methods are inconvenient to adjust and cannot meet the precise installation requirements in both width and depth directions at the same time.

[0006] Disadvantages of existing technology: Large-sized, integrated car roofs are difficult to transport and install, resulting in high costs.

[0007] Ventilation, lighting and other devices are installed independently, occupy a lot of space, have a complex structure, many parts, and are cumbersome to install.

[0008] The car top and the straight beam connection structure have poor adjustment capabilities, making it difficult to meet the high-precision installation requirements of heavy-duty elevators. At the same time, the vibration and noise during elevator operation will be directly transmitted to the car through the straight beam.

[0009] The overall structure is complex, and the manufacturing and subsequent maintenance costs are high. Utility Model Content

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 As shown, a split-type car top structure for a heavy-duty elevator includes multiple splicable car top panels 1. These panels together form the main body of the car top. The car top panels 1 are made of steel plates and are spliced ​​and fixed together by connectors. The car top is constructed from multiple independent car top panels 1 assembled in sections to accommodate large-size requirements and solve transportation and installation challenges. The specific number and shape of the sections can be designed according to the actual car top dimensions (e.g., two panels, three panels, etc.). Specifically, the car roof panel 1 is equipped with reinforcing ribs; The car roof panel 1 is also equipped with a ventilation device 2 and a lighting device 3; The ventilation device 2 is directly fixedly installed on the reinforcing rib of at least one car top plate 1. Specifically, the ventilation device 2 is a fan, which is fixed to the reinforcing rib by bolts. The car top plate 1 that supports the ventilation device 2 has ventilation openings, which correspond to the air inlet or air outlet of the ventilation device 2. The car roof ventilation device 2 (such as a fan) is directly fixed to the reinforcing ribs of the car roof panel 1 itself. This utilizes the strength and space of the reinforcing ribs, eliminating the need for additional brackets or mounting plates.

[0031] Ventilation openings are made in the area of ​​the car roof panel 1 that supports the ventilation device 2 (usually between or near the reinforcing ribs). Airflow path: outside air -> ventilation opening -> ventilation device 2 -> car interior.

[0032] The same car roof panel 1 structure simultaneously undertakes three functions: structural support, bearing ventilation equipment, and forming a ventilation channel, significantly reducing the number of parts and lowering the structural height.

[0033] The lighting device 3 is directly installed on the lower surface of the car roof panel 1; specifically, the lighting device 3 is an LED downlight, which is clipped onto the lower surface of the car roof panel 1.

[0034] The car roof lighting device 3 (LED downlight) is directly installed on the lower surface of the car roof panel 1 (the side facing the interior of the car). This eliminates the need for traditional ceiling panels or light fixture brackets, resulting in an extremely simple structure and more direct light distribution.

[0035] Two car top plates 1 near the straight beams on both sides of the car top are provided with straight beam clips 4. The straight beam clips 4 are provided with several elongated holes for installation and connection. The elongated holes include a first set of elongated holes arranged along the width of the car and a second set of elongated holes arranged along the depth of the car.

[0036] Furthermore, the straight beam clip 4 is bolted to the car roof plate 1; the number of the first set of elongated holes and the second set of elongated holes are both at least two.

[0037] The straight beam clip 4 is installed on the car roof plate 1 (usually on the outer side) near the straight beams on both sides of the car roof.

[0038] Structure: The straight beam clip 4 is a specially designed mounting component, which is bolted to the car top plate 1. As the size of the car changes, the installation position of the straight beam clip 4 on the car top plate 1 is not fixed. To adapt to this situation, several elongated holes for installing the straight beam clip 4 are designed on the two car top plates 1 near the straight beam position, so as to ensure the installation of the straight beam clip 4 and the standardization of the product.

[0039] Meanwhile, the U-shaped straight beam card 4 is designed with several cylindrical rubber springs on three sides, so that the straight beam card 4 and the straight beam form point contact, reducing the contact area; thus, the car top and the straight beam are flexibly connected, which plays a role in vibration damping and noise reduction.

[0040] Several elongated holes are installed on the car top and the straight beam 4. The spacing and orientation of these elongated holes need to be carefully designed: The major axis of some of the elongated holes is along the width direction of the car (X direction), and is used to adjust the installation position of the car top relative to the straight beam in the width direction.

[0041] The major axis of some of the elongated holes is along the depth direction (Y direction) of the car, and is used to adjust the installation position of the car top relative to the straight beam in the depth direction.

[0042] Some elongated holes can be designed to be angled, or small-angle adjustments can be achieved through combinations.

[0043] By using the elongated hole and connecting bolts, the installation position can be flexibly and precisely adjusted in both width and depth directions, ensuring the stability and alignment accuracy of the connection between the car top and the straight beam under heavy load conditions.

[0044] The above design (split structure, integrated ventilation, integrated lighting, and optimized straight beam clip 4) together constitute a car roof system that is simple in structure, has few parts, is easy to manufacture, and is convenient and efficient to install.

[0045] This application has the following advantages: Effectively solves the problem of large size: The split design makes the transportation and installation of large car roofs in the shaft feasible and convenient, reducing logistics and installation costs and difficulties.

[0046] Highly integrated and with a simplified structure: The ventilation device 2 is integrated into the reinforcing rib, the ventilation opening is opened in the top plate, and the lighting is directly mounted below, which greatly reduces the number of independent parts (eliminating ventilation brackets, part of the ceiling structure, light fixture brackets, etc.) and simplifies the overall structure.

[0047] Reduce manufacturing costs: Fewer parts and a simplified structure directly reduce raw material costs and processing and assembly costs.

[0048] Optimized space utilization: The reduction of stacked structures effectively lowers the total thickness of the car roof (structural height), providing more space for hoistway design or car clearance.

[0049] Easy and efficient installation: The split design facilitates transportation and operation within the shaft.

[0050] Integration reduces the number of components that need to be installed separately.

[0051] The bidirectional elongated hole design on the four straight beam clamps makes the connection, installation, and adjustment of the car top and the hoistway straight beam convenient, fast, and precise. It is particularly suitable for the strict requirements of installation accuracy for heavy-duty elevators, significantly improving installation efficiency and quality.

[0052] Easy to maintain: The simple structure and segmented design make it easy to inspect or replace individual components (such as ventilation or lighting on a certain top panel) later.

[0053] High reliability: The reinforced ribs support the ventilation device 2, ensuring strength; the optimized straight beam installation ensures a stable connection.

[0054] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
