Problems solved by technology
However, because the emergency stop of the hoisting cage will bring greater impact, and the hinged connection between the pressure plate and the bracket is relatively flexible, there is a problem that the pressure plate bounces from the travel switch or even moves away from the travel switch when the hoisting cage is in an emergency stop. The direction is reversed, thereby causing the risk of secondary accidents, so that the anti-overrunning device cannot reliably play the role of preventing the cage from overcoming the roof

Embodiment Construction
[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0020] see figure 1 with figure 2 , shows the structure of the anti-shock device for the construction elevator provided by the embodiment of the present invention. For the convenience of description, figure 1 The structure of some components of the construction hoist is also shown in . According to the prior art, the construction hoist mainly includes a guide rail frame and a lifting device that can move longitudinally along the guide rail frame. Among them, the guide rail frame includes a frame body formed by a plurality of stacked standard sections ( figure 1 Not shown in), and the rack 81 and guide rail fixedly installed on the frame ( figure 1 Not shown in), the height of the rack 81 ...

The invention provides a building hoist and an anti-piercing device thereof. The anti-piercing device comprises an installation seat, a pressing block and a travel switch. The installation seat is installed at the top of a lifting device and provided with a slideway arranged obliquely. The pressing block is in sliding fit with the slideway. Downward sliding of the pressing block is limited by a guide rail bracket. The pressing block comprises a trigger part. The travel switch is installed on the glide path of the trigger part. By the adoption of the anti-piercing device, piercing of a cage can be avoided reliably; and in addition, the structure is simple, and the cost is low.
Description
technical field [0001] The invention relates to the field of elevators, and more specifically, to a construction elevator and an anti-shock device thereof. Background technique [0002] Construction elevators are also called construction elevators for construction, and can also be called outdoor elevators and construction site elevators. They are often used in construction to carry people and cargo. They are mainly used for interior and exterior decoration of high-rise buildings, construction of bridges, chimneys and other buildings. The construction hoist mainly includes a guide rail frame and a lifting device that can move longitudinally along the guide rail frame. Wherein, the guide rail frame includes a frame body formed by a plurality of stacked standard sections, and a rack and a guide rail installed on the frame body, and the height of the rack body is basically the same as that of the frame body. The lifting device includes a cage and a driving part. The cage can mo...
