Abstract

The utility model discloses a building lifting device which comprises a hopper car, a lifting motor, a lifting tower, a spring, a pulley wheel, a cranking handle, a wire rope and a portal frame, wherein the portal frame and the lifting tower are both installed on a construction floor; the lower end of the portal frame is hinged on a base seat arranged at the edge of the construction floor; the lifting motor is installed on a cross beam of the portal frame; the pulley wheel is fixed on the lifting tower; one end of the wire rope is fixedly connected with the portal frame, the other end that passes through the spring and the pulley wheel is fixed on a center shaft of the cranking handle; a plurality of positioning wire ropes are fixed between the portal frame and the lifting tower. The utility model has the advantages of simple structure, little space occupation, light weight, low manufacturing accuracy requirement, no need of enormous installation foundation, and convenient installation, and the utility model is especially suitable for rural areas without convenient traffic.

Description

A kind of building bont

Technical field

The utility model relates to a kind of building bont that uses when building building.

Background technology

At present, widely used during the building at lid is the tower crane gig, and its weak point is: 1. complex structure, take up room big, own wt is big, accuracy of manufacture requirement height, involve great expense; 2. the transport amount is big back and forth; 3. must build huge installation basis; 4. adorn, must employ crane and technical sophistication in addition when tearing open; 5. architecture storey is high more, and the structure of tower crane gig is complicated more, and transportation and dress, the work capacity when tearing open is big more; 6. limited owing to the tower crane arm lengths, as build wide, long floor and must just can finish by the tower crane gig more than two; 7. because tower crane gig height, self is heavy, adds that the heavy training pouring weight of postbrachium should not move fast, work efficiency is low; 8. tower crane mechanism is many, must just can finish transport by a plurality of motors, and power consumption is many.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, take up room little, own wt is light, accuracy of manufacture is less demanding, inexpensive suitable building bont, it need not be huge the installation basis, it is convenient to install, be specially adapted to ungetable rural area, and the structure of bont is not subjected to the influence of architecture storey height, build ten floors and two floors and can not have more a facility, this device need only just can be worked power saving by a motor.

For achieving the above object, the building bont that the utility model relates to, comprise trolley, lifting motor, spring, pulley, rocking-turn handle and steel rope, it is characterized in that also comprising and be installed in the portal frame on the construction floor and play tower crane, the portal frame lower end links on the pedestal at construction floor edge, like this, portal frame can rotate around its lower end, the lifting motor is installed on the crossbeam of portal frame, pulley has been fixed on the tower crane, steel rope one end captive joint portal frame, the other end are fixed on the center shaft of rocking-turn handle after by spring and pulley.

As further improvement of the utility model, between a portal frame and a tower crane, also be fixed with several positioning wire ropes.

As further improvement of the utility model, below described trolley, be provided with a folding shuttle groove.

Fig. 4 is the front view of trolley.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of building bont of the present utility model, comprise the trolley 1 that has a Foldable shuttle groove, lifting motor 2, spring 4, pulley 5, rocking-turn handle 7 and steel rope 8, it is characterized in that also comprising and be installed in the portal frame 9 on the construction floor and play tower crane 3, portal frame 9 lower ends link on the pedestal at construction floor edge, like this, portal frame 9 can rotate around its lower end, lifting motor 2 is installed on the crossbeam of portal frame 9, pulley 5 has been fixed on the tower crane 3, steel rope 8 one end captive joint portal frames 9, the other end is fixed on the center shaft of rocking-turn handle 7 after by spring 4 and pulley 5, at portal frame 9 with rise between the tower crane 3 and also be fixed with two positioning wire ropes 10.

Operating process of the present utility model is: start lifting motor 2, the trolley 1 that will install material (as cement concrete) rises to the height of construction floor, and this moment, trolley 1 was positioned at outside, floor edge, shake handle 7, portal frame 9 inwardly is pulled to the inside, floor edge, counter-rotating lifting motor 2, put down trolley 1, construct, simultaneously, can hang up another sky trolley, counter-rotating handle 7, portal frame 9 is pushed to outside, floor edge under the effect of spring 4, put down the trolley charging.Like this, construction and feeding are carried out simultaneously, can improve work efficiency.

Positioning wire rope 10 may command portal frames 9 exceed the position outside the floor edge.

The setting of shuttle groove, but convenient construction.After shifting trolley 1 onto destination, put down the shuttle groove, just open drain hole, put material after, put on the shuttle groove, just shut drain hole.

Because after using building bont of the present utility model to transport material, mostly be manual operation in the operation of construction floor, can use wooden handcart as annex of the present utility model, with convenient as prefabricated board and so on transporting of part greatly; For making things convenient for moving of trolley, wooden handcart, can on the construction flooring, lay panel.

Claims

1. building bont, comprise trolley, lifting motor, spring, pulley, rocking-turn handle and steel rope, it is characterized in that also comprising and be installed in the portal frame on the construction floor and play tower crane, the portal frame lower end links on the pedestal at construction floor edge, the lifting motor is installed on the crossbeam of portal frame, pulley has been fixed on the tower crane, and steel rope one end captive joint portal frame, the other end are fixed on the center shaft of rocking-turn handle after by spring and pulley.

2. a kind of building bont according to claim 1 is characterized in that at portal frame and rises between the tower crane also being fixed with several positioning wire ropes.
