[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Ports are warehouses and open-air yards used to store and preserve goods to be shipped. Port yards are the main distribution centers for water-borne goods, and play an important role in shortening the stay time of vehicles and ships, speeding up cargo turnover, and improving freight quality. Port warehouses are mainly used for short-term storage of goods that are not suitable for sun and rain and valuable goods that are easy to lose; yards are mainly used to store bulk cargo and barreled and containerized goods that are not afraid of sun and rain.

[0032] Port warehouses usually include reinforced concrete frame structures, multi-span reinforced concrete frame structures, and reinforced concrete hyperbolic barrel arch roof warehouses. The first structure: reinforced concrete thin-web beams or roof trusses, prefabricated reinforced concrete columns and large roof panels, brick walls or reinforced concrete wall panels for enclosure. This structure is suitable for various special warehouses in auxiliary construction areas with small and medium spans; the second structure: used for large warehouses in front of the port, with a variety of combined spans. This structure mostly uses standard components and is easy to construct, but adding columns in the warehouse will reduce the effective storage capacity, which is not conducive to mechanized operations; the third structure: the arch span can reach more than 40m, which is suitable for large-span warehouses, and the structural forms are diverse, such as saddle-shaped roofs.

[0033] Its port warehouses are divided into: piece goods warehouses, bulk cargo warehouses, dangerous goods warehouses and cold storages according to the types of goods stored; according to location: divided into front warehouses and rear warehouses. The front warehouse is located in the front of the dock and is directly related to the ship loading and unloading operations; the rear warehouse is located at the rear of the port area and is used for long-term storage of goods; according to characteristics: divided into special warehouses and general warehouses, single-story warehouses and multi-story warehouses, etc.

[0034] However, the basic construction of port warehouses is supported by columns. The vertical state of the columns ensures the storage safety of goods inside the warehouse. The verticality of the columns is currently detected by total station or three-dimensional laser measurement methods.

[0035] This method is only applicable to places with better column positions. When the warehouse storage is closed, the space is small, the light is dim, and the column surface is rough, there are problems such as difficulty in equipment installation and poor signal reception, resulting in low detection efficiency, unstable results and large deviations from the actual situation. It is difficult to meet the needs of structural inspection during the operation period of port warehouses.

[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a verticality detection device for a warehouse column in a port area, including a load-bearing platform 1 and a column 2:

[0037] A column 2 is provided on one side of the carrying platform 1, and a notch 3 is provided on the upper surface of the carrying platform 1;

[0038] The inside of the slot 3 is fixedly connected with a connecting shaft 310, the outer surface of the connecting shaft 310 is rotatably connected with an arc-shaped receiving block 370, the upper surface of the arc-shaped receiving block 370 is bolted with an electric push rod fixed end 330, the upper end of the electric push rod fixed end 330 is internally installed with an electric push rod output end 331, the outer side of the electric push rod output end 331 is provided with a scale line 332, the upper end of the electric push rod output end 331 is hinged with a flat plate 333, the outer side wall of the electric push rod fixed end 330 is bolted with an inclinometer 340, the outer surface of the connecting shaft 310 is movably connected with a mounting block 350, the outer side of the mounting block 350 is fixedly connected to the inner side wall of the slot 3, the upper surface of the mounting block 350 is bolted with a laser rangefinder 360, the upper surface of the carrying platform 1 is provided with a computing display component 4, and the inclinometer 340 and the laser rangefinder 360 are data-connected with the computing display component 4.

[0039] During the inspection, the electric push rod fixed end 330 and the electric push rod output end 331 form an electric push rod to replace the inclinometer rod, drive the output length of the electric push rod output end 331, and at the same time push the electric push rod fixed end 330 to tilt, so that the side of the flat plate 333 hinged at the top of the electric push rod output end 331 fits the side of the column 2. Since the length of the electric push rod fixed end 330 is fixed, before the inspection, the length of the electric push rod fixed end 330 can be measured first, and then the length of the electric push rod output end 331 can be measured according to the length of the fixed end 330 of the electric push rod. The length is compared with the scale line 332 set thereon, and the extension length of the electric push rod as the inclinometer is added together. At this time, the inclinometer 340 and the laser rangefinder 360 set on the fixed end 330 of the electric push rod can be used for measurement to know the inclination angle and the distance between the end point of the fixed end 330 of the electric push rod and the column 2. The data is communicated with the calculation and display component 4 through the data of the two, and enters the interior of the calculation and display component 4. Then, the extension length of the electric push rod is input and the verticality of the column 2 is obtained by matching the function;

[0040] Further, the basic formula for calculating the function inside the display component 4 is: Wherein θ is the verticality, ; is the reading of the laser rangefinder 360, L is the sum of the length of the fixed end 330 of the electric push rod and the extended length of the output end 331 of the electric push rod, and a is the reading of the inclinometer 340.

[0041] As a preferred technical solution of the present invention, spiral lifters 120 are provided at both ends of the front side of the lower surface of the carrying platform 1, and the spiral lifters 120 include a connecting sleeve 124, an adjusting block 123 and a screw member 122.

The internal thread of the adjusting block 123 is connected to the screw member 122, and the outer surface of the screw member 122 is movably connected to the inside of the connecting sleeve 124, and the lower end of the screw member 122 is fixedly connected to the pulley bracket 121.

[0042] By rotating the adjusting block 123 , the adjusting block 123 moves on the outer surface of the screw member 122 , and synchronously drives the connecting sleeve 124 connected to the adjusting block 123 to move up and down, so that the height of the carrying platform 1 can be adjusted.

[0043] As a preferred technical solution of the present invention, a U-shaped block 130 is fixedly connected to the bottom of the supporting platform 1, and the interior of the U-shaped block 130 is rotatably connected to a rotating shaft 131, and a connecting rope 135 is wrapped around the outer surface of the rotating shaft 131, and the other end of the connecting rope 135 is fixedly connected to a threaded connecting rod 133, and the lower surface of the arc-shaped supporting block 370 is fixedly connected to a connecting block 320, and the end of the threaded connecting rod 133 passes through the interior of the connecting block 320, and the threaded connecting rod 133 passes through the outer surface of the end of the connecting block 320 and is threadedly connected to a limiting block 134, and one side of the limiting block 134 is fitted with the other side of the connecting block 320, and a motor 132 is installed on the lower surface of the supporting platform 1, and the output shaft of the motor 132 is fixedly connected to the rotating shaft 131.

[0044] When testing is performed, the motor 132 drives the rotating shaft 131 to rotate, and the rotating shaft 131 unwinds a relatively long connecting rope 135, which facilitates the subsequent angle adjustment of the fixed end 330 of the electric push rod. When the testing is completed, the motor 132 drives the rotating shaft 131 to rotate, so that the rotating shaft 131 reels in the connecting rope 135, and the connecting rope 135 pulls the arc-shaped receiving block 370 through the connecting block 320 to reset, thereby resetting the electric push rod assembly, which is convenient for subsequent testing.

[0045] Furthermore, the end of the connecting rope 135 is connected to a threaded connecting rod 133, which is passed through the interior of the connecting block 320 and then threadedly connected to the outer surface of the end of the threaded connecting rod 133 through a limiting block 134, thereby assembling the connecting rope 135 and the connecting block 320.

[0046] As a preferred technical solution of the present invention, handrails 5 are fixedly connected to both sides of the upper surface of the carrying platform 1, and fixed brackets 110 are fixedly connected to both ends of the rear side of the lower surface of the carrying platform 1.

[0049] During the inspection, the device is moved as a whole to one side of the column 2, at which time the central axis 150 is facing one side of the column 2, and by observing the level meter 140, it is determined whether the bearing platform 1 and the column 2 are on the same horizontal line. If they are not on the same horizontal line, the spiral lifter 120 is used for fine adjustment to ensure that they are on the same horizontal line;

[0050] Furthermore, the initial end of the light beam of the laser rangefinder 360 is located on the central axis of the connecting shaft 310 , thereby ensuring the distance accuracy between the fixed end 330 of the electric push rod and the column 2 .

[0051] As a preferred technical solution of the present invention, a portion of the surface of one side of the arc-shaped receiving block 370 is in contact with the inner wall of the slot 3 , and the arc-shaped receiving block 370 and the mounting block 350 are cocentric with the connecting shaft 310 .
