Description

(54) CONSTRUCTION LIFT

one

The invention relates to lifting mechanisms, namely to construction hoists.

A construction elevator is known, which contains a frame with an arrow installed fa adjustable racks with a boom, a cargo truck with a rope, a boom rounding around the boom blocks and an unsecured cargo container, a boom extension locking device and a locking device for the container's upper position.

The disadvantage of the known lift is its limited functionality and relatively low productivity.

The purpose of the invention is to increase productivity and enhance the functionality of the elevator.

The goal is achieved by being installed with a vertical inclination in the direction of the container, and the boom is mounted for movement along the frame, with the cargo winch mounted on the container, the counterweight is suspended to one end of the rope, and the other end is fixed to the frame

The fixture of the boom extension device consists of a plate with a shaped groove rigidly fixed to the frame and a lever pivotally connected to the boom interacting with the container body, the lever being provided with a roller, which interacts with the shaped plate groove.

In addition, the locking device in the top position of the container consists of an eyelet on the container with tilt stop.

Claims (3)

The elevator consists of supports 1, height-adjustable struts 2, frame 3 with boom 4 mounted on rails that can be moved along them on rollers 5, cargo container 6 equipped with rollers 7 interacting with the building surface, cargo winch 8 of friction clips onnobarabnbgo type with a reversible electric motor and brake system, a rope of a cargo winch 9 fixed in the upper part of the frame of the boom passed through the blocks of 10, stocked on the drums of the cargo winch 8 and equipped with a counterweight 11. When mounted on ryshe ra ma lift equipped beam 12 and counterweight 13, and when installed in claim Birmingham LDani Carrier with counterweight can be replaced with height-adjustable vertical struts (not shown in the diagrams). The boom 4 is equipped with two locking devices, a locking device for extending the boom, interacting with the guides of the frame 3 and a cargo container 6 when it approaches the upper point of the path, and a locking device of the upper position of the cargo container b relative to the boom, interacting with the guides when moving arrows along them. The locking device for boom movement consists of a plate 14 with a figured groove rigidly fixed to the frame and a hinged lever 15 connected to the strap, which interacts with the container body, and the lever 1 is provided with a roller that interacts with the plate shaped groove. The locking device of the upper position of the container consists of a patch mounted on the container. 17, mounted on the boom rod 18 with a spring 19, which interacts with the eye of the container. On the frame 3 of the lift, there is an inclined stop 20, and on the boom there is a movable pin with roller 21. A finger with a flexible pin 22 through blocks with a spring-loaded rod 18. Lifting | in the following way . Load - the cargo container 6 with freight. Include cargo winch. The cargo container begins to rise, rollers 7, touching the surface of the railway. When approaching the top point of the way, the freight container b lifts the lever 15 of the locking device for moving the boom, while the roller 16 leaves the shaped groove of the plate 14 and releases the boom of the lift. The cargo container B, continuing its way upwards, reaches the stop of the boom (see Fig. 4), which leads to its movement along the frame guides inside the building together with the cargo container. At the same time, the finger roller 21 is moved along the inclined stop 20, which leads to a weakening of the tension of the flexible connection passing through the blocks and, under the action of the spring 19, the rod enters the eye of the cargo container 17, fixing its upper position relative to the lift arm . The boom 4 with the cargo container 6 is stopped at the desired location by turning off the power to drive the winch. At the same time the brake of the winch works. After loading and unloading operations include a winch drive in the opposite direction. An arrow with a cargo container fixed on it moves along the frame guides towards the outer wall of the building. The tilting of the guides allows the boom to move in reverse with the cargo container even in the absence of cargo. When the boom approaches the outer end of the guides, the finger roller, moving along the inclined stop, rises, pulling the flexible connection, which, compressing the spring 19, takes the rod out of engagement with the cargo container. The freight container, being lowered, releases the lever 16, which causes the boom to be fixed in the outermost position relative to the guides. Claim 1. A construction hoist comprising a frame with an arrow mounted on adjustable racks, a cargo winch with a rope around the boom blocks and a carrying cargo container, a boom extension locking device and a container upper locking device, characterized in that expanding the functionality of the elevator, the frame is installed with a vertical inclination towards the container, and the boom is mounted for movement along the frame, and the cargo winch is mounted on a container, to one end of which a counterweight is suspended, and the other end is fixed to the frame. 2. The elevator according to claim 1, characterized in that the locking device of the boom extension consists of a plate with a figured groove rigidly fixed to the frame and a lever hinged to the boom, which interacts with the container body, and the lever is provided with a roller interacting with the figured plastier groove. 3. The elevator according to claim 1, characterized in that the locking device of the upper position of the container consists of an eyelet mounted on the container, mounted on a boom of a spring-loaded serge, interacting with an eye, mounted on an inclined support frame, and mounted on the boom movably 57980156 th finger connected by a flexible t - Sources of information goy with a spring-loaded rod and taken into account in the examination of a roller interacting c1.
