The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
According to an embodiment of the present utility model, a kind of tower crane device is provided, as shown in Figure 1, comprise: pedestal 10, the first end of first cantilever 30 is rotatably installed on the pedestal 10, and first cantilever 30 also has the second end, and the second end is provided with rotatable ring flange 31, intermediolateral column 40 with hollow structure is installed on the ring flange 31 by second bearing pin, so intermediolateral column 40 can rotate together with ring flange 31; Outer cover at intermediolateral column 40 is equipped with lifting unit 50, is provided with first slide block 70 between intermediolateral column 40 and lifting unit 50, and this first slide block 70 is sleeved on the intermediolateral column 40 slidably; Lifting unit 50 has wallboard 51, and wallboard 51 is screwed onto on the surrounded surface of first slide block 70, and 50 of lifting units are connected by wallboard 51 and first slide block 70, are sleeved on slidably on the intermediolateral column 40.Only need pull down wallboard 51 when lifting unit 50 breaks down can keep in repair lifting unit 50, greatly facilitates field maintenance work, has improved maintenance work efficient.
In Fig. 1, also show, lifting unit 50 also comprises the base plate 52 that is arranged on lifting unit 50 bottoms, the upper surface of base plate 52 is equipped with electric pushrod 53 by first bearing pin 54, be connected with extension bar 55 on the electric pushrod 53, unshowned in the drawings, extension bar 55 stretches into the hollow structure of intermediolateral column 40, and passes from this hollow structure on the ring flange 31 on the second end that is installed in first cantilever 30.
Before using the tower crane device, need regulate first installation site of slide block 70 on intermediolateral column 40 according to the situation of load, regulate lifting unit 50 equilibrated purposes to reach, after first slide block 70 is adjusted to suitable position, with screw first slide block 70 is fixed on the intermediolateral column 40, guaranteeing that first slide block 70 can not glide voluntarily gets final product, and subsequently wallboard 51 is installed on the surrounded surface of first slide block 70.When lifting unit 50 needed to descend, electric pushrod 53 outwards extended, because the extension bar 55 that is connected with electric pushrod 53 is fixed on the ring flange 31 of first cantilever 30, therefore, moved downward along with electric pushrod 53 outside elongations then drive lifting unit 50; When lifting unit 50 needs to rise, then control electric pushrod 53 retractions, rise thereby drive lifting unit 50.
Because the pretightning force that first slide block 70 applies by screw is fixed on the intermediolateral column 40, in order to guarantee that lifting unit 50 slides up and down swimmingly, as shown in Figure 3, on the outer surface of intermediolateral column 40, be processed with sliding tray, and the inwall of first slide block 70 is provided with first slide protrusion 71 that matches with sliding tray all around, in order to reduce fricative noise, to avoid producing cut, first slide protrusion 71 is provided with felt, can clear up the sliding tray on the intermediolateral column 40 when first slide block 70 slides.
Preferably, the stainless steel wire drawing plate can also be installed in sliding tray.
In tower crane device illustrated in fig. 2, between the pedestal 10 and first cantilever 30, also be provided with second cantilever 20, one end of second cantilever 20 rotatably is connected on the pedestal 10, and the first end of first cantilever 30 rotatably is connected the other end of second cantilever 20.So just can make the tower crane device cover bigger range of application, practical more.
Simultaneously, in Fig. 2, also show second slide block 90 that is sleeved on the intermediolateral column 40.
Figure 3 illustrates first slide block 70 and second slide block 90 and be installed in position relation on the intermediolateral column 40.Identical with first slide block 70, second slide block 90 is provided with second slide protrusion 91 that matches with sliding tray, and is arranged on the felt on second slide protrusion 91, and wallboard 51 is screwed onto on the surrounded surface of first slide block 70 and second slide block 90 simultaneously.The balance that two slide blocks more help regulating lifting unit 50 is set on intermediolateral column 40, because when load is big, often deficiency need be according to the definite quantity of using slide block of the situation of load so that lifting unit 50 reaches balance only according to a slide block.
As can be seen from the above description, this utility model the above embodiments have realized following technique effect:
Tower crane device according to this utility model embodiment, employing is equipped with the lifting unit of wallboard, and wallboard is installed on the slide block, when having avoided slide block to slide and the friction of lifting unit inwall, effectively reduced noise, prolonged the service life of tower crane, and owing to wallboard can be pulled down from slide block, for the maintenance of tower crane device is also provided convenience.
The slip that the stainless steel wire drawing plate helps slide block is set in the sliding tray of intermediolateral column, and felt is set on the slide protrusion of slide block, help reducing the noise between the sliding tray of slide block and intermediolateral column, and can also play the effect of the sliding tray of cleaning intermediolateral column along with the slip felt of slide block.
The above is a preferred embodiment of the present utility model only, is not limited to this utility model, and for a person skilled in the art, this utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
