Detailed Description
Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the tower crane 100 of the present embodiment mainly includes a base 12, a tower body 11, a balance arm 1, a crane arm 3, and a cab 8. In the example shown in fig. 1, the crawler-type running gear 13 is provided below the base 12, but the present utility model is not limited to this, and for example, a track-type running gear may be used, or the base 12 may be directly fixed to the ground without providing a running gear.
The tower body 11 is vertically arranged on the base 12. The tower body 11 laterally supports a balance arm 1 and a boom 3, which are disposed in succession with each other, above it via a swing mechanism, not shown in the drawings, so as to be capable of horizontally swinging. As shown in fig. 2 and 3, a cab 8 is provided at the top of the tower 11 at a position laterally to the boom 1 and the boom 3. The driver 8 may be provided at a position higher than the upper beams of the boom 1 and the arm 3, but the present utility model is not limited thereto, and for example, the cab 8 may be provided lower than the upper beams of the boom 1 and the arm 3. The operator can perform various operations on the tower crane 100 by a control device provided in the cab 8.
As shown in fig. 1 and 4, a sub-trolley 9 is suspended on the boom 7 so as to be movable laterally along the boom 7. A lifting hook 10 for hanging the goods is arranged below the auxiliary trolley 9. On the other hand, as shown in fig. 1 and 2, a lifting mechanism 7 is provided at the projecting end of the balance arm 1. The balance arm 1 is further provided with a counterweight, an electric box, and the like.
The lifting mechanism 7 lifts and lowers a hook 10 provided in the sub-trolley 9 by a suspension rope, thereby lifting and lowering a load suspended from the hook 10 in the vertical direction. Further, the load suspended on the hook 10 can be transported laterally by the movement of the sub-carriage 9 in the lateral direction of the boom 3. Further, the boom 3 and the balance arm 1 perform a pivoting operation with respect to the tower body 1 via the pivoting mechanism, whereby the cargo suspended by the sub-trolley 9 and the hook 10 thereof can be pivoted together with the boom 3. The lifting of the load by the tower crane 100 is achieved by the pivoting motion of the boom 3 and the balance arm 1, the lateral movement of the sub-trolley 9, and the lifting of the hook 10 in the up-down direction described above.
According to the present embodiment, as can be seen from fig. 1 and 2, an observation platform 6 is provided on top of the boom 3 and the balance arm 1. The observation platform 6 is provided along the longitudinal direction of the boom 3 and the balance arm 1, and is rotatable together with the boom 3 and the balance arm. In the example shown in fig. 2, the width of the observation platform 6 is substantially the same as the width of the boom 3 and the counter arm 1. As shown in fig. 1 and 4, a protective rail 4 is preferably provided around the observation deck 6. By providing the balustrade 4, the safety of the operator who works on the observation platform can be increased, and the safety of the work can be improved.
In the present embodiment, as shown in fig. 3, an elevator 5 that can be lifted and lowered in the vertical direction is provided along a tower body 11 on the side of the tower body 11 where the cab 8 is provided. In the example shown in fig. 3, the elevator 5 is directed to the cab 8 (i.e., the elevator 5 is directed into the cab 8). A connection platform 2 for connecting the cab 8 and the observation platform 6 is provided between them.
By means of the book-loading structure, the operator can take the elevator 5 directly from the base 12 of the tower 100 to the cab 8 and walk from the cab 8 into the observation platform 6 via the connection platform 2. Therefore, operators can reach almost any position on the crane boom 3 and the balance boom 1 on the observation platform 6, can safely and conveniently maintain and detect the tower crane, observe the construction environment around the tower crane and comprehensively master the construction condition. For example, as shown in fig. 4, an operator may stand behind the balustrade 4 on the observation platform 6 to safely observe the sub-trolley 9, the hook 10, and/or the load (not shown) hung on the hook 10, which are moved to the end of the boom 3, so as to timely grasp the operation of the apparatus, or the hanging condition of the load, etc.
The above description of the tower machine with an elevator direct observation platform according to the present utility model is given as an exemplary embodiment. However, the present utility model is not limited to the above-described embodiments, but various modifications and improvements can be made within the scope not departing from the gist of the present utility model.
For example, in another embodiment shown in fig. 5, the elevator 5 does not reach directly into the cab 8, but into the connecting platform 2 provided between the cab 8 and the observation platform 6. According to this real-time manner, the operator first takes the elevator 5 from the base 12 to the connection platform 2, however, it is possible to access the observation platform 6 from one side of the connection platform 2 or to access the cab 8 from the other side of the connection platform 2 at the discretion of the operator.
In the embodiment shown in the drawings, the elevator 5 and the cab 8 are provided on the same side of the tower 11, but the elevator and the cab may be provided on both sides of the tower 11. However, in this case, the operator must pass through the observation platform before entering the cab after arriving at the top of the tower 11 by taking the elevator. Therefore, this approach is not optimal from the standpoint of saving the walking distance of the operator.
Further, in the embodiment shown in fig. 2, the width of the observation platform 6 is formed to be substantially the same as the widths of the boom 3 and the balance arm 1, and for example, in the case of a large-sized tower crane, the width of the sightseeing platform 6 may be 5.5m. However, the present utility model is not limited thereto, and the width of the observation platform may be formed at least partially wider than the widths of the boom 3 and the balance arm 1, or the width of the observation platform may be formed wider than the widths of the boom 3 and the balance arm 1 over the entire length thereof.
For example, in the plan view shown in fig. 6, an embodiment in which the width of the observation platform 6 is partially formed wider than the widths of the boom 3 and the balance arm 1 is shown. In the embodiment of fig. 6, the observation platform 6 protrudes on both sides in the width direction on the side near the end of the boom 3, forming a substantially circular platform portion. By adopting such a structure, the movable range of the operator on the side of the end portion of the observation platform 6 close to the boom 3 can be increased, so that the lifting condition of the cargo can be observed better.
In the present utility model, the observation platform 6 may be integrally formed and integrally assembled to the balance arm 1 and the boom 3, or may be formed by combining a plurality of separate parts, which are assembled to the balance arm 1 and the boom 3, respectively. As an example in which the observation platform 6 is composed of a combination of separate parts, for example, in the embodiment shown in fig. 6, the observation platform 6 may be formed in two parts: a substantially rectangular portion provided along the balance arm 1 and the boom 3, and a substantially disk-shaped portion near the end of the boom; and, these two parts are assembled separately.
The present utility model is described above with reference to the drawings, in which a specific embodiment is described. By adopting the tower crane with the direct elevator observation platform in the embodiments, an operator can conveniently reach the observation platform through the elevator, and can conveniently and safely carry out maintenance operation on the observation platform and carry out omnibearing observation on the construction conditions of the tower crane and the periphery thereof. Therefore, the problems that in the prior art, the safety coefficient is low, the movable range is limited, the operator can only climb to the walking table, and the whole tower crane and the surrounding construction environment cannot be intuitively and comprehensively observed are solved.
