技术领域Technical field
本发明属于强制驱动电梯领域,具体涉及到一种可降低楼顶施工量的电梯。The invention belongs to the field of forced drive elevators, and specifically relates to an elevator that can reduce the amount of roof construction.
背景技术Background technique
为了防止电梯上行或下行过快,发生事故,一般会在电梯的两侧安装安全钳,当电梯运行超速时会触发限速器动作,限速器钢丝绳通过安全钳提拉机构使安全钳动作,安全钳夹住电梯导轨制停电梯轿厢。现In order to prevent the elevator from going up or down too fast and causing an accident, safety gears are usually installed on both sides of the elevator. When the elevator runs overspeed, the speed limiter will be triggered. The speed limiter wire rope passes through the safety gear lifting mechanism to make the safety gear act. The safety gear clamps the elevator guide rail to stop the elevator car. now
在现有技术中,由于房屋结构的限制,别墅电梯井道顶层高度和地坑深度都较小。但是现有的别墅电梯中,强制驱动电梯的安全钳通常采用安全钳上置结构,这种结构往往需要占用较大的井道顶层与底坑空间,同时结构较为复杂,成本较高。同时,为了匹配现有技术中反绳轮支撑梁的安装需求,井道顶部反绳轮支撑梁需要预留梁孔洞。但是目前的别墅建设中,多数电梯井道无预留孔洞或预留孔洞尺寸误差过大,对后期电梯安装带来了不利影响,不仅需要后期对井道重新施工,而且增加了后期电梯安装的工作量。顶层高度有限,反绳轮支撑梁和限速器支架无更多安装空间。因此,需重新优化设计电梯结构。In the prior art, due to the limitations of the house structure, the top height of the villa elevator shaft and the depth of the pit are both small. However, in existing villa elevators, the safety gear of the forced-drive elevator usually adopts a safety gear-mounted structure. This structure often requires a large space on the top and bottom of the hoistway. At the same time, the structure is relatively complex and the cost is high. At the same time, in order to meet the installation requirements of the anti-sheave support beam in the existing technology, beam holes need to be reserved for the anti-sheave support beam at the top of the hoistway. However, in the current villa construction, most elevator shafts have no reserved holes or the size error of the reserved holes is too large, which has a negative impact on the later elevator installation. Not only does the shaft need to be re-constructed later, but it also increases the workload of the later elevator installation. . The height of the top floor is limited, and there is no more installation space for the anti-sheave support beam and speed governor bracket. Therefore, the elevator structure needs to be redesigned.
