According to the utility model, the standard joint platform is fixed with the fixed blocks according to the welding pin shafts in four directions, the standard joint connecting pin shafts are inserted into the fixed blocks, and the connecting pin shafts are strung up and fixed with the platform by the lock pins, so that the connecting pin shafts cannot be strung or fall off, and the tower crane can be installed by directly taking down the lock pins and taking out the connecting pin shafts, so that the installation preparation time is greatly reduced, the time and the labor are saved, and the problem that the time is wasted when the connecting pin shafts are found in the past is solved.
Description
Technical Field
The utility model relates to the technical field of tower cranes, in particular to a novel standard joint pin shaft storage structure of a tower crane.
Background
The connecting pin shaft used by the standard section of the tower crane is generally stored in a packing box in the delivery process, and needs to be turned in the packing box when being installed on site.
Disclosure of Invention
In order to solve the problems that a connecting pin shaft used by the existing standard knot of the tower crane is difficult to find during installation and installation efficiency is influenced, the utility model provides a novel pin shaft storage structure for the standard knot of the tower crane.
In order to achieve the purpose, the utility model provides the following technical scheme:
a novel standard joint pin shaft storage structure of a tower crane comprises a tower crane standard joint and a standard joint platform, wherein fixed blocks are arranged at four included angles of the standard joint platform at the bottom of the tower crane standard joint, and a plurality of connecting holes are formed in the fixed blocks and used for inserting and placing connecting pin shafts; the lock pin penetrates through the pin hole of the connecting pin shaft, the lock pin is a plastic piece, the appearance of one end of the lock pin is larger than that of the pin hole, the appearance of the other end of the lock pin is smaller than that of the pin hole, and a transverse notch is formed in the middle of one end, the appearance of the lock pin is smaller than that of the pin hole.
Preferably, the fixed block is made of channel steel.
Preferably, vertical notches perpendicular to the transverse notches are arranged on the upper side and the lower side of one end, which is smaller than the pin hole, of the lock pin in appearance.
Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, the standard joint platform is fixed with the fixed blocks according to the welding pin shafts in four directions, the standard joint connecting pin shafts are inserted into the fixed blocks, and the connecting pin shafts are strung up and fixed with the platform by the lock pins, so that the connecting pin shafts cannot be strung or fall off, and the tower crane can be installed by directly taking down the lock pins and taking out the connecting pin shafts, so that the installation preparation time is greatly reduced, the time and the labor are saved, and the problem that the time is wasted when the connecting pin shafts are found in the past is solved.

Detailed Description
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description and simplicity of description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
As shown in fig. 1 to 4, the embodiment of the utility model comprises a tower crane standard knot and a standard knot platform, wherein four included angles of the standard knot platform 2 at the bottom of the tower crane standard knot 1 are respectively provided with a fixed block 3, and the fixed block 3 is provided with two connecting holes 4 for inserting and placing connecting pin shafts 5; a lock pin 6 penetrates through the pin hole of the connecting pin shaft 5, the lock pin 6 is a plastic piece, the appearance of one end of the lock pin 6 is larger than that of the pin hole, the appearance of the other end of the lock pin is smaller than that of the pin hole, a transverse notch 61 is arranged in the middle of one end of the lock pin 6, which is smaller than the pin hole, and vertical notches 62 perpendicular to the transverse notch 61 are arranged on the upper side and the lower side of the lock pin.
Taking a fixing block 3 as an example, firstly, two connecting pin shafts 5 penetrate through the connecting holes 4, the pin holes of the connecting pin shafts are correspondingly communicated, then one end of the lock pin 6, the shape of which is smaller than the pin holes, sequentially penetrates through the pin holes of the two connecting pin shafts 5, the upper side and the lower side of the transverse notch 61 are pulled outwards to be larger than the diameter of the pin holes, the lock pin 6 cannot be separated from the pin holes under the action of no external force, the pin shafts cannot move in a string mode or fall off, and the end parts of the lock pin 6 can be more conveniently pulled by the vertical notch 61 perpendicular to the transverse notch 61. When the standard knot 1 of the tower crane is installed, the lock pin 6 is a plastic piece, so that the lock pin can be directly pulled out of the pin hole of the connecting pin shaft 5 by force, and then the connecting pin shaft 5 is taken out of the connecting hole 4 of the fixing block 3, so that the installation preparation time is greatly reduced, time and labor are saved, and the problem that the time is consumed by finding the pin shaft in the past is solved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
