Description

A light portable mobile hoisting device

technical field

The utility model relates to a hoisting device, in particular to a light portable mobile hoisting device, which is used for hoisting light materials and equipment on a construction site, and belongs to the technical field of building construction equipment.

Background technique

In the construction of the main structure of a small high-rise building, after the completion of the secondary structure construction, the permanent elevator designed by the building cannot be put into use at this time, and it is often faced with an embarrassing situation: whether to remove the temporary construction elevator? After dismantling, how to transport materials and small equipment? At present, there is no finished product hoisting equipment specially designed to solve such problems in the construction field. In the construction of some unitized curtain walls, self-made single-arm cranes similar to tower cranes or placing hoisting equipment in the floor are used. This equipment is relatively large and heavy. , when encountering the shear wall or some narrow spaces on the roof, the space for display is relatively limited. At the same time, the control system (switch) of this kind of equipment is set near the equipment. When lifting objects on the top floor, it is necessary to use a walkie-talkie to maintain a dialogue with the operator on the ground floor for control. The visibility is poor, the coordination is poor, and the construction efficiency is low. Also relatively low.

Utility model content

Purpose of the utility model: The purpose of this utility model is to provide a light portable mobile hoisting device for the deficiencies of the prior art. The ground part can be easily moved and operated, and at the same time, the volume of the upper fulcrum is reduced for flexible arrangement, which improves the hoisting operation. sex and work efficiency.

Technical solution: A light portable mobile hoisting device described in the utility model includes a hoisting system placed on the ground, a hoisting system installed on the roof and steel wire ropes. The hoisting system includes a ground machine base, a hoist and Counterweight, the hoist and the counterweight are fixed on the ground machine base, the hoisting system includes a roof machine base, a wall-riding member and a hoisting frame, the wall-riding member is clamped on the parapet, and the inner side of the wall-riding member is connected to the roof The machine base is fixedly connected, and the outer side is fixedly connected with the hoisting frame. The roof machine base is provided with a counterweight, and the top of the hoisting frame is provided with a pulley. There is a hook at the top. This equipment uses a winch as a lifting mechanism, and a fixed pulley as a hoisting cable guide, so that the hoisted objects pass through the winch and pulleys to be hoisted to the installation site.

To further improve the above technical solution: the ground machine base is provided with a screw jacking device to ensure that the equipment does not slip during operation.

Further: casters are installed on the bottom surface of the ground base to facilitate the movement of the equipment.

To further improve the above technical solution: the hoisting frame includes a diagonal tie rod and a support rod, the bottom end of the diagonal stay rod is fixed on the wall-riding member, and the support rod is fixed between the diagonal stay rod and the wall-riding member.

Further: a stiffener is provided between the wall-riding member and the roof frame.

Compared with the prior art, the utility model has the beneficial effects as follows: (1) the lifting device described in the utility model has a simple structure, and the lifting system is placed on the ground, which can be easily moved and used flexibly; (2) the control system (Switch) can be placed next to the hoist, and controlled and operated next to the equipment. It has better visualization and is convenient for the command of the crane. It can quickly and orderly complete the hoisting operation, reducing the construction cost and accident rate; (3) The hoisting system layout is flexible , The roof occupies less space, avoiding the phenomenon that the local space is too small to place hoisting equipment.

Detailed ways

The technical solutions of the utility model are described in detail below, but the protection scope of the utility model is not limited to the embodiments.

Embodiment 1: As shown in Figures 1 to 4, a light portable mobile hoisting device includes a hoisting system placed on the ground, a hoisting system and a wire rope 14 placed on the roof.

The hoisting system includes a ground frame 1, a hoist 2 and a counterweight 3, the counterweight 3 is fixed in the middle of the ground frame 1, the hoist 2 is fixed on the ground frame 1 adjacent to the counterweight 3, and the The ground machine base 1 is provided with a screw jacking device 4 to ensure that the equipment does not slip during operation, and casters 5 are installed on the bottom surface of the ground machine base 1 to facilitate the movement of the equipment.

The hoisting system includes a roof machine base 6, a wall-riding member 7, a hoisting frame and a counterweight 3. The wall-riding member 7 is clamped on the parapet wall, and the inner side of the wall-riding member 7 is fixedly connected to the roof machine base 6, specifically connected The method is: one end of the roof frame 6 is directly embedded into the U-shaped connector 9 on the wall-mounted member 7 through the L-shaped connector 8 for fixing, and a stiffener 10 is provided between the wall-mounted member 7 and the roof frame.
