Abstract
The utility model discloses a tower crane with a trailer pump. The tower crane comprises a tower crane body and a trailer pump; a weight arm is arranged on the tower crane body; the trailer pump comprises a pump body and a conveying pipe; the weight arm is connected with the tower crane body through a rotating universal joint; the weight arm is connected to a folding arm which can be folded and stretched; and the conveying pipe straight extends to the folding arm along the tower crane body and the weight arm. The tower crane with the trailer pump disclosed by the utility model and the trailer pump are combined; concrete is pumped to an appointed operation surface by utilizing the rotating arm of the tower crane and the concrete conveying pipe of the trailer pump; and the working efficiency is increased.
Description
Technical field
The utility model relates to a kind of tower machine, and specifically a kind of tower crane with dragging pump belongs to tower machine field.
Background technology
Quickening along with Modernized City Construction speed, and the continuous increase of depth of building, and the narrow bottleneck that has become the operation of restriction pump truck of the vertical pumping height of concrete pump truck and camp site, the limitation of concrete pump construction operation is apparent, affected concrete pumping because of the height of building body, increase work difficulty, reduced work efficiency.
The utility model content
In order to address the above problem, the utility model has designed a kind of tower crane with dragging pump, with tower crane and drag pump to combine, utilizes the pivot arm of tower crane and drags the concrete delivery pipe of pump, concrete pump is delivered to the scope of operation of appointment, has improved work efficiency.
The technical solution of the utility model is:
A kind of tower crane with dragging pump, comprise tower machine body and drag pump, described tower machine body is provided with weight arm, the described pump that drags comprises the pump housing and delivery pipe, described weight arm links to each other with described tower machine body by rotatable universal-joint, described weight arm be connected with can folding retractable folding arm, described delivery pipe extends to folding arm along described tower machine body and weight arm always.
Further, the cross-directional length of described delivery pipe is that the extreme length after the weight arm rotation axis is opened to folding arm is no more than 30 meters, and oversize the generation can be because of pump concrete the time laid particular stress on, and the danger rank occur.
Further, the vertical-direction length of described delivery pipe is advisable with 2 times of tower machine body standard knot, so both can reduce joint, and Assembly ﹠Disassembly easily again can also be supporting with tower crane well.
Further, described folding arm is linked to each other with motor by HM Hydraulic Motor by fluid control.In addition, comprise that rotation, lifting and dolly slide etc. all to use HM Hydraulic Motor, only need an electrical motor just can finish whole operations.
In addition,, usually the tower machine is fixed on the building sustaining wall by securing device because tower crane is too high to be produced the tower machine acutely to rock even collapse for preventing.This securing device comprises a stull and a diagonal brace, a part of weight of tower crane will be shared by building like this, the gravity of weight that adds lifting when the deadweight of tower crane is always downward along the standard knot of tower crane, will produce several component, approximately be that the above tower crane of day point reloads the deadweight component that the date of arrival, point produced strut later on that about 90% of lotus summation is tower crane certainly, this component approximately is that tower crane is from reloading about 10% of lotus summation, Action of Gravity Field is after stull, the outside thrust that stull also can produce, and the sustaining wall pull bar is to the pulling force of tower crane generation.As long as and then the jacking along with tower crane reaches the height that needs, a sustaining wall just is installed, how high no matter the tower crane jacking has so, tower crane self is only born the above weight of the highest sustaining wall.In other words, how high no matter tower crane rises, his deadweight has not been problem.
In addition, can also three acting point be set at sustaining wall, form triangular structure, sustaining wall and tower crane intersection arrange two acting point, and be well-known, and circular and triangle is figure the most stable in the plane geometry, these five points are all coupled together, if will form individual triangle, two acting point of sustaining wall and tower crane intersection are respectively these leg-of-mutton two summits, thereby further improve the stability of tower crane.
The utility model has the advantage of: with tower crane and drag pump to combine, utilize the pivot arm of tower crane and drag the concrete delivery pipe of pump, concrete pump is delivered to the scope of operation of appointment, improved work efficiency.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Among the figure: 1-tower machine body, 2-drag pump, 3-weight arm, 4-delivery pipe, 5-folding arm.
The specific embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, a kind of tower crane with dragging pump, comprise tower machine body 1 and drag pump 2, described tower machine body is provided with weight arm 3, the described pump 2 that drags comprises the pump housing and delivery pipe 4, described weight arm 3 links to each other with described tower machine body 1 by rotatable universal-joint, described weight arm 3 be connected with can folding retractable folding arm 5, described delivery pipe 4 extends to folding arm 5 along described tower machine body 1 and weight arm 3 always.
In addition, the cross-directional length of delivery pipe 4 is that the extreme length after the weight arm rotation axis is opened to folding arm is no more than 30 meters, and oversize the generation can be because of pump concrete the time laid particular stress on, and the danger rank occur.The vertical-direction length of delivery pipe 4 is advisable with 2 times of tower machine body standard knot, so both can reduce joint, and Assembly ﹠Disassembly easily again can also be supporting with tower crane well.
Folding arm 5 is linked to each other with motor by HM Hydraulic Motor by fluid control.In addition, comprise that rotation, lifting and dolly slide etc. all to use HM Hydraulic Motor, only need an electrical motor just can finish whole operations.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
