Abstract
The utility model discloses a lifting tower hoist, which is mainly composed of a base, a tower body and a hanging and conveying device, wherein, the tower body is generally composed of a lower tower section which can be fixed corresponding to the base and an upper tower section which can be lifted and lowered, and the hanging and conveying device is supported by the top of the upper tower section. The utility model is characterized in that the upper parts of the left side and the right side of the lower tower section are respectively fixed with a fixed pulley; one end of two pulling ropes is respectively fixed on the left side and the right side of the lower part of the upper tower section, and the other end is connected with a hoisting power source respectively through a left fixed pulley and a right fixed pulley. The utility model can be used for rise and fall rapidly, the stress of the upper tower section is balanced, the problem of uneven stress of a tower body and the easy deflection and the easy jam of rise and fall can not occur when one side of the utility model is pulled, and thus, the stability and the reliability of the work of the lifting tower hoist are increased, and the free and the safety of hoisting operation are ensured.
Description
The utility model relates to a kind of lifting machine, the elevation tower lifting machine that especially a kind of body of the tower of overhead hoist can lifting.
In order to satisfy the construction needs of small building projects such as building houses of countryside, the small-sized lifting machines such as right angle trolley that are transformed into walker tractor receive an acclaim.The body of the tower that supports the small-sized lifting machine of this class is formed by saving with base relatively-stationary tower down joint and last tower that can lifting usually, wherein descend the tower joint to go up fixedly fixed pulley, last tower joint is connected with movable pulley, last tower joint top braces overhead hoist, trailing cable one end is fixed on down tower joint top, and the other end connects the elevator propulsion source through movable pulley, fixed pulley.Its mechanism's essence has been used for reference the movable and fixed pulley group principle in the physics.Because the lifting of last tower joint relies on the one-sided traction through the fixed pulley changed course, the problem of easy deflection clamping stagnation when therefore above-mentioned lifting machine in use exists body of the tower unbalance stress, lifting.
The purpose of this utility model is: at the problem that above-mentioned lifting machine in use exists, propose stressed evenly, the elevation tower hoisting machine that can not the deflection clamping stagnation of a kind of body of the tower lifting, thereby improve the performance of hoisting machine, guarantee safety of operation.
In order to achieve the above object, elevation tower hoisting machine of the present utility model mainly is made up of base, body of the tower, overhead hoist, body of the tower constitutes by saving with relatively-stationary down tower joint of base and last tower that can lifting usually, last tower joint top braces overhead hoist, its innovative design part is that down tower saves at least top, the left and right sides fixing fixed pulley respectively, one end of two trailing cables is separately fixed at the tower joint left and right sides, bottom, and the other end connects the elevator propulsion source through left and right fixed pulley respectively.
When elevation tower hoisting machine of the present utility model was worked, the elevator propulsion source produced synchronous castering action by at least two trailing cables to last tower joint simultaneously.Like this, not only lifting is rapid, and goes up tower joint stress equalization, the problem of body of the tower unbalance stress, the easy deflection clamping stagnation of lifting in the time of monolateral traction can not occurring, thereby improved the stability and the reliability of the work of elevation tower hoisting machine, guaranteed that lifting is operated freely, safety.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment running condition of the utility model.
The elevation tower hoisting machine of present embodiment mainly is made up of base 8, body of the tower, overhead hoist 1, body of the tower constitutes by saving 2 with the relatively-stationary towers down of base 8 joint 4 and last tower that can lifting usually, last tower saves 2 top braces overhead hoist 1, following tower saves 4 and arranged on left and right sides tops fixing fixed pulley 3 and 9 respectively, two trailing cables 5 and an end of 10 are separately fixed at tower and save 2 bottom and arranged on left and right sides, the other end (on-fixed end) through left and right fixed pulley 3 and 9 and fixed pulley 6, connects same elevator propulsion source 7 respectively.When this elevator propulsion source 7 rotated, two trailing cables 3 and 9 promote synchronously from and arranged on left and right sides respectively went up tower joint 2, makes its stable rising.Like this, only need an elevator power to get final product, thereby make this elevation tower hoisting machine simple in structure, cost is lower.In addition, on last tower joint 2, the lifting guiding mechanism of being made up of roller and rolling wheel support 11 is housed also, the roller of this mechanism can be along the guided way operation on the following tower joint 4, thereby can beat when having guaranteed that last tower saves 2 liftings, has further improved the stability and the reliability of the work of elevation tower hoisting machine.
Except the foregoing description, the utility model also has other embodiments, for example combines with the Chinese patent of having authorized " more piece interlock flexible tower ladder " technology and the more piece elevation tower hoisting machine that produces etc.In a word, all employings are equal to and replace or technical scheme that equivalent transformation forms is protection domain of the present utility model.
Claims (3)
1. elevation tower hoisting machine, mainly form by base, body of the tower, overhead hoist, body of the tower constitutes by saving with relatively-stationary down tower joint of base and last tower that can lifting usually, last tower joint top braces overhead hoist, it is characterized in that: following tower saves at least and arranged on left and right sides top fixing fixed pulley respectively, one end of two trailing cables is separately fixed at tower joint bottom and arranged on left and right sides, and the other end connects the elevator propulsion source through left and right fixed pulley respectively.
2. elevation tower hoisting machine according to claim 1 is characterized in that: the on-fixed end of described two trailing cables connects same elevator propulsion source respectively behind left and right fixed pulley.
3. elevation tower hoisting machine according to claim 1 is characterized in that: described going up on the tower joint also is equipped with the lifting guiding mechanism of being made up of roller and rolling wheel support, and the roller of this mechanism can be along the guided way operation on tower saves down.
