The following describes a quay crane trapezoid assembly according to an embodiment of the present invention in detail with reference to the accompanying drawings.
As shown in fig. 1-3, the quay crane trapezoid assembly according to the embodiment of the invention comprises a sea-side upper cross beam, two dome 1, a plurality of clamping codes 2 and a trapezoid frame. Two dome space 1 are respectively fixed at two ends of the upper surface of the sea side upper cross beam; a plurality of clamping codes 2 are arranged on the upper surfaces of the two dome-shaped space 1; the ladder-shaped frame comprises two supporting pipes 3, the bottom ends of the two supporting pipes 3 are respectively fixed on the upper surfaces of the two dome regions 1, and a plurality of clamping codes 2 are attached to the inner walls of the supporting pipes 3.
The prior installation method of the ladder frame and the sea side upper cross beam is that a plurality of clamping codes 2 for guiding are firstly installed on the upper surface of a dome 1, then a supporting tube 3 of the ladder frame is installed among the plurality of clamping codes 2, and after the installation, the temporary clamping codes 2 are removed for structural stress and attractive appearance of components.
However, in the process of removing the card code 2, high altitude fire operation is required, and dust generated by cutting and polishing causes pollution and damage to painted components and environments to different degrees, so that the production process and the manufacturing cost are increased.
According to the invention, the guiding mode is changed from external guiding to internal guiding, and the bottom end of the supporting tube 3 of the assembled ladder frame is arranged outside the clamping code 2, so that the clamping code 2 is supported on the inner wall of the supporting tube 3, and the ladder frame can be used for positioning and guiding without affecting the attractive appearance of the component and without cutting. Compared with the prior quay crane trapezoidal component, the invention has the following specific advantages:
1) The qualification rate of the ribs is high: the rib plate contour line of the rib is drawn out of the dome 1 on the sea side upper beam and the rib is aligned with the ladder frame support tube 3 during prefabrication, the clamping code 2 is tightly attached to the inner wall of the support tube 3 to enter the support tube 3 during installation of the ladder frame, the support tube 3 of the ladder frame is installed on the dome 1 along the clamping code 2, therefore, the ladder frame cannot deviate during installation, and rib alignment accuracy of the ladder frame support tube 3 and the dome 1 is guaranteed.
2) The construction safety is high: the weight of the clamping code 2 is reduced by about 3.4kg, the clamping code can be positioned by one hand and one person, and the construction safety is further improved.
3) The material quantity is reduced: the prior quay crane ladder-shaped component can be provided with a large number of clamping codes 2 for improving the stability, the workload is larger, the more the quantity is, the higher the error rate is, and the clamping codes 2 are clung to the inner wall of the ladder-shaped frame support tube 3, so the stability of the ladder-shaped frame can be ensured without installing too many clamping codes 2, the installation workload is greatly reduced, and the error rate is reduced.
4) Post-paint exempt from to cut: after the installation is finished, the clamping code 2 is fixed in the supporting tube 3, and the appearance of the whole framework is not affected, so that the clamping code 2 does not need to be cut off, the fire operation required by cutting off the clamping code 2 is omitted, and the generation of polishing dust in the cutting off process is avoided.
Further, the clamping code 2 further comprises a support, the support is fixed on the upper surface of the dome 1, and the clamping code 2 is fixed on the support.
The mounting of the card 2 is preceded by mounting the holder at a predetermined position and then mounting the card 2 on the holder. The card code 2 is the position of the trapezoidal bridge component with larger stress, and the damage probability is larger, if damage occurs, the card code 2 can be directly detached from the support, and the bridge component is more convenient.
Further, as shown in fig. 3, the plurality of card codes 2 includes three.
The clamping code 2 is tightly attached to the inner wall of the ladder frame supporting tube 3, so that the stability of the ladder frame can be ensured without installing excessive clamping codes 2. Compared with the current mode of installing seven clamping codes 2 on one dome 1, the invention adopts the mode of installing three clamping codes 2 on one dome 1, thereby not only ensuring the stability of one surface of three points, but also greatly reducing the installation quantity and reducing the workload.
Further, as shown in fig. 2, the height of the side of the two dome 1 away from each other is greater than the height of the side close to each other.
Because of the trapezoid structure, the supporting tube 3 of the trapezoid frame is not in vertical relation with the horizontal plane, and in order to facilitate installation of the trapezoid frame, the inclination of the upper surfaces of the two dome places 1 is kept consistent with the inclination of the supporting tube 3 as much as possible.
Further, as shown in fig. 2, the width of the upper end of the code is smaller than the width of the lower end.
In the installation process of the support tube 3, the opening at the bottom end of the support tube 3 moves downwards along the edge of the clamping code 2 from the upper end of the clamping code 2, and the structure with the narrow upper part and the wide lower part can play a role in guiding, so that the movement of the support tube 3 is smoother in the process of starting to contact the clamping code 2.
Further, as shown in fig. 1, the sea side upper beam includes a connection cross frame 4, two connection tables 5. The connection table 5 is formed in a round table shape, two connection tables 5 are respectively connected to two ends of the connection transverse frame 4, and two dome places 1 are respectively connected to the two connection tables 5.
The sea side upper cross beam is a bearing part of the whole quay crane trapezoid assembly, and the two connecting tables 5 are main bearing structures of the sea side upper cross beam, and the connecting tables 5 are in a round table shape, so that the structure is stable.

The invention changes the outer guide into the inner guide, namely, reduces the installation distance between the clamping codes 2, and then the supporting tube 3 is sleeved outside the clamping codes 2, so that the clamping codes 2 are supported on the inner wall of the supporting tube 3. The mode omits the process of cutting off the clamping code 2, thereby not affecting the beautiful appearance of the component, but not generating polishing dust.
Further, step S30 includes: mounting a support on the upper surface of the dome 1; the card code 2 is arranged on the support.
And a support is additionally arranged between the dome 1 and the clamping code 2, so that the clamping code 2 is convenient to maintain and replace.
Further, the method further comprises the step S6: measuring the assembled size of the assembled quay crane trapezoid assembly through three-dimensional measuring equipment; step S7: judging whether the assembly size of the assembled quay bridge trapezoidal component is qualified or not, if so, finishing the assembly, and if not, adjusting the assembly size of the quay bridge trapezoidal component until the assembly size is qualified.
