Description

Technical Field

[0001] The utility model relates to the technical field of bridge cranes, in particular to a positioning and scribing device for installing a limit scale base. Background Art

[0002] With the transformation and upgrading of the port industry, port equipment has also begun to move towards modernization, automation, and intelligence. Bridge cranes and gantry cranes have started to apply new technologies and developed into automated and semi-automated bridge cranes and automated gantry cranes. The application of advanced equipment requires strong technical support. Advanced port equipment requires various detection limits to constantly feedback the equipment operation status to the control system terminal. The detection of the position of the bridge crane trolley uses this technology, which can feedback various data of the trolley operation to the data terminal, so as to achieve remote control.

[0003] At present, bridge cranes generally adopt a semi-automated control system. In order to detect the position of the trolley assembly in real time, trolley limit scales need to be installed on the front and rear girders. The trolley limit scales are arranged on the limit scale bases. The bridge crane needs to position and weld 168 limit scale bases. How can we ensure that these 168 limit scale bases are on the same straight line and have the same height? The earliest scribing process relied on traditional scribing methods to measure the dimensions at the welding positions of the limit scale bases on the front and rear girders for scribing, which had the disadvantage of large scribing errors. Later, after the bridge crane was fully installed, scribing was carried out during the commissioning stage. An induction limit position positioning marker pen was installed at the trolley assembly of the bridge crane. By running the trolley of the bridge crane, the positioning line of the limit scale base was scribed on the side of the front and rear girders. This process method requires all mechanisms of the bridge crane to be fully installed, with scribing, positioning, and welding at high altitude, which belongs to high-altitude operation, has a large construction difficulty, and has potential safety hazards of falling objects from high altitude. In addition, the construction period during the commissioning stage of the bridge crane is tight. It takes at least 5 days to weld and install the trolley induction scale base, seriously affecting the commissioning period. Summary of the Utility Model

[0004] In order to overcome the defects of large scribing errors, large construction difficulty of high-altitude operation, and potential safety hazards in the prior art, the utility model provides a positioning and scribing device for installing a limit scale base.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a positioning and scribing device for installing a limit scale base, including a scribing trolley installed on the trolley assembly track of the girder. A vertical rod is installed on the scribing trolley, and a horizontal rod that can move up and down along the axis of the vertical rod is penetrated and connected to the vertical rod. One end of the horizontal rod is penetrated and connected with a fixed seat that can move left and right along the axis of the horizontal rod. A marker pen is clamped on the fixed seat. A universal spirit level is arranged on the scribing trolley, and a cylindrical spirit level is arranged on the horizontal rod.

[0006] As a further improvement of the present utility model, positioning plates for limiting the scribing trolley are provided on both sides of the track of the trolley assembly.

[0007] As a further improvement of the present utility model, eight groups of ball small wheels are evenly distributed at the bottom of the scribing trolley.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to make the technical solutions and beneficial effects of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0017] The installation requirements for the scale on the gantry crane girder are of very high precision. While ensuring that the straightness error of the scale itself does not exceed 1 mm and the spacing error between each scale does not exceed 0.5 mm, it is also necessary to ensure that each scale is parallel to the trolley assembly track, with the horizontal dimension error not exceeding 1 mm and the height error not exceeding 1 mm. Along with the camber of the trolley track, the dimensions of some trolley scales also change accordingly.

[0018] Referring to Figure 1 and Figure 2 , an embodiment of the present invention discloses a positioning and marking device for installing a limit scale base, including a marking trolley 1 installed on the trolley assembly track 12 of the girder. A vertical rod 4 is installed on the marking trolley 1, and a horizontal rod 5 that can move up and down along the axis of the vertical rod 4 is connected through the vertical rod 4. One end of the horizontal rod 5 is connected through a fixing seat 7 that can move left and right along the axis of the horizontal rod 5. A marking pen 8 is clamped on the fixing seat 7. A universal spirit level 10 is provided on the marking trolley 1, and a cylindrical spirit level 11 is provided on the horizontal rod 5.

[0019] Among them, a rib plate 13 for fixing the vertical rod 4 is provided on the marking trolley 1, thereby improving the stability of the vertical rod 4.

[0020] During use, a universal spirit level 10 is provided on the marking trolley 1 for detecting the levelness of the marking trolley 1, and a cylindrical spirit level 11 is provided on the horizontal rod 5 for detecting the levelness of the horizontal rod 5. The vertical rod 4 and the horizontal rod 5 are connected and fixed through an up and down adjustment knob 6. The horizontal rod 5 and the fixing seat 7 are connected and fixed through a left and right adjustment knob 9. A marking pen 8 is clamped on the fixing seat 7. The vertical rod 4 is installed on the marking trolley 1, and the marking trolley 1 is installed on the trolley assembly track 12. The construction workers are on the ground and move the marking trolley 1 along the trolley assembly track 12 to perform positioning and marking of the limit scale base on the sides of the front and rear girders, and weld the base on the ground and install the trolley scale limit on the ground, reducing high-altitude operations and improving operation safety.

[0021] Taking the trolley assembly track 12 of the gantry crane as a reference, the parallel lines of the trolley track can be accurately drawn on the sides of the front and rear girders. Compared with the traditional marking method, the accuracy of marking is increased, and at least 3 / 4 of the time is saved. It solves the conflict between the debugging process and the welding base process, shortens the debugging time, ensures the construction period, and improves the production efficiency.

[0022] Positioning plates 2 for limiting the marking trolley 1 are provided on both sides of the trolley assembly track 12. The positioning plates 2 are made of plexiglass and play a role of positioning and guiding. The specification of the trolley assembly track 12 is A100, that is, the track width is 100 mm, and the inner width of the two positioning plates 2 on both sides of the marking trolley 1 is 100 mm + 0.5 mm, ensuring that the marking trolley 1 can be stuck on the trolley assembly track 12 to move in a straight line.

[0023] Eight groups of ball casters 3 are evenly distributed at the bottom of the scribing trolley 1. The ball caster 3 has the characteristics of small volume, large load-bearing capacity and convenient fixation, and is fixed at the bottom of the scribing trolley 1.

[0024] It should be understood that the specific embodiments described herein are only for understanding the present utility model and are not used to limit the present utility model.
