[0001] This invention relates to the field of column testing technology, specifically a verticality testing device for columns in port warehouses. Background Technology

[0002] Port warehouses are buildings used in port areas for the temporary and short-term storage of cargo for loading and unloading, including land-based and water-based warehouses.

[0003] During the operation of port warehouses, regular structural inspections are crucial. However, in practice, there are many difficulties in inspecting the verticality of warehouse columns. Traditional total station or 3D laser measurement methods suffer from problems such as difficulty in equipment setup and poor signal reception under conditions of enclosed storage, small space, dim lighting, and rough column surfaces. This results in low inspection efficiency, unstable results, and significant deviations from the actual situation, making it difficult to meet the structural inspection needs of port warehouses during operation.

[0004] Therefore, it is necessary to propose a verticality detection device for warehouse columns in port areas. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a port warehouse column verticality detection device, which is easy to operate and accurate in measurement, and effectively overcomes the limitations of existing technologies in confined spaces and low-light environments, thus solving the problems mentioned in the background art.

[0006] This invention provides the following technical solution: a port warehouse column verticality detection device, comprising a support platform and columns:

[0007] A column is provided on one side of the support platform, and a slot is opened on the upper surface of the support platform;

A laser rangefinder is bolted to the upper surface of the mounting block.

[0009] Preferably, a screw lifter is provided at both ends of the front side of the lower surface of the bearing platform. The screw lifter includes a connecting sleeve, an adjusting block, and a screw rod. The connecting sleeve is fixedly connected to both ends of the front side of the lower surface of the bearing platform. The adjusting block is rotatably sleeved at the lower end of the connecting sleeve. The screw rod is internally threaded to the adjusting block. The outer surface of the screw rod is movably connected to the interior of the connecting sleeve. The lower end of the screw rod is fixedly connected to a wheel bracket.

[0010] Preferably, a U-shaped block is fixedly connected to the bottom of the bearing platform, a rotating shaft is rotatably connected inside the U-shaped block, a connecting rope is wound around the outer surface of the rotating shaft, and a threaded connecting rod is fixedly connected to the other end of the connecting rope.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This port warehouse column verticality detection device uses an electric push rod, consisting of a fixed end and an output end, to replace the inclinometer. Driving the output end of the electric push rod increases its output length, while simultaneously tilting the fixed end. This causes the side of the flat plate hinged at the top of the output end to fit against the side of the column. An inclinometer and laser rangefinder mounted on the fixed end of the electric push rod can then measure the tilt angle and the distance between the fixed end and the column. This data is input into a calculation and display component connected to the inclinometer and laser rangefinder. The verticality of the column is determined by a built-in calculation function within the calculation and display component. This structure, through the combined use of various components and the function calculation method, ensures the accuracy of the detection, reduces errors caused by excessive human intervention, and features simple and convenient detection components for easy operation.

[0018] 2. This port warehouse column verticality testing device, by incorporating a screw lifter, allows for adjustment of the support platform's height. Combined with a level for auxiliary use, it enables fine-tuning of the platform's horizontal position, ensuring its horizontal operation. The addition of a wheeled bracket and handrails facilitates device mobility, enabling testing between different port warehouse columns, saving testing costs and time. Furthermore, the device is adaptable to special environments, employing a contact measurement scheme that effectively overcomes the problems of difficulty in moving testing equipment and measurement failures in confined indoor spaces and low light conditions. It is particularly suitable for measuring column verticality during structural inspections in port areas and warehouses during their operational phase. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Port warehouses and open storage yards are used for storing and storing goods awaiting shipment. Port warehouses are the main distribution centers for waterborne goods and play an important role in shortening the dwell time of vehicles and ships, speeding up the turnover of goods, and improving the quality of freight transportation. Port warehouses are mainly used for short-term storage of goods that are not suitable for exposure to sunlight and rain and valuable goods that are easily lost; storage yards are mainly used for storing bulk cargo and barrelled or boxed goods that are not afraid of exposure to sunlight and rain.

[0032] Port warehouses typically include reinforced concrete frame structures, multi-span reinforced concrete frame structures, and reinforced concrete hyperbolic arch roof warehouses. The first type uses thin-webbed reinforced concrete beams or roof trusses, precast reinforced concrete columns, and large roof panels, enclosed by brick or reinforced concrete walls. This structure is suitable for various specialized warehouses in auxiliary areas with small to medium spans. The second type is used for large warehouses in front of the port, featuring various combined spans. This structure often uses standard components, making construction easy, but adding columns inside the warehouse reduces the effective storage capacity and is not conducive to mechanized operations. The third type has arch spans exceeding 40m, suitable for large-span warehouses, and offers diverse structural forms, such as saddle-shaped roofs.

[0033] Its port warehouses are classified according to the type of goods stored: piece cargo warehouses, bulk cargo warehouses, dangerous goods warehouses, and cold storage warehouses; according to location: they are divided into front warehouses and rear warehouses. Front warehouses are located at the front of the wharf and are directly related to ship loading and unloading operations; rear warehouses are located at the rear of the port area and are used for long-term storage of goods; according to characteristics: they are divided into dedicated warehouses and general-purpose warehouses, single-story warehouses and multi-story warehouses, etc.

[0034] However, the basic construction of port warehouses is supported by columns. The verticality of the columns ensures the safety of the goods stored inside the warehouse. Currently, the verticality of the columns is tested by measuring with a total station or a 3D laser instrument.

[0035] This method is only suitable for locations with good column positions. When the warehouse is enclosed, the space is small, the lighting is dim, and the column surface is rough, there are problems such as difficulty in setting up the equipment and poor signal reception, resulting in low detection efficiency, unstable results, and large deviations from the actual situation, making it difficult to meet the needs of structural inspection during the operation of port warehouses.

[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The port area warehouse column verticality detection device includes a support platform 1 and a column 2.

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

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

[0039] During testing, an electric actuator, consisting of a fixed end 330 and an output end 331, replaces the inclinometer rod. The output length of the output end 331 is driven, simultaneously tilting the fixed end 330. This causes the side of the plate 333 hinged at the top of the output end 331 to fit against the side of the column 2. Since the length of the fixed end 330 is fixed, it can be measured before testing. Then, the length of the output end 331 can be used to determine the inclinometer rod's length. The length is compared with the scale line 332 set on it, and the two lengths are added to obtain the extension length of the electric push rod, which serves as the inclinometer rod. At this time, the inclinometer 340 and laser rangefinder 360 set on the fixed end 330 of the electric push rod can be used to measure the tilt angle and the distance between the end point of the fixed end 330 of the electric push rod and the column 2. This data is communicated with the data of the calculation and display component 4 and enters the internal of the calculation and display component 4. Then, by inputting the extension length of the electric push rod, the verticality of the column 2 is obtained in conjunction with the function.

[0040] Furthermore, the basic formula for the function inside component 4 is calculated as follows: Where θ is the verticality, ; is the laser rangefinder reading 360, L is the sum of the length of the fixed end 330 of the electric actuator and the extension length of the output end 331 of the electric actuator, and a is the inclinometer reading 340.

[0041] As a preferred technical solution of the present invention, a screw lifter 120 is provided at both ends of the front side of the lower surface of the bearing platform 1. The screw lifter 120 includes a connecting sleeve 124, an adjusting block 123 and a screw member 122. The connecting sleeve 124 is fixedly connected to both ends of the front side of the lower surface of the bearing platform 1. The adjusting block 123 is rotatably sleeved at the lower end of the connecting sleeve 124. The screw member 122 is threadedly connected to the inside of the adjusting block 123. The outer surface of the screw member 122 is movably connected to the inside of the connecting sleeve 124. The lower end of the screw member 122 is fixedly connected to a wheel bracket 121.

[0042] By rotating the adjusting block 123, the adjusting block 123 moves on the outer surface of the screw 122, and synchronously drives the connecting sleeve 124 connected to the adjusting block 123 to move up and down, thereby adjusting the height of the bearing platform 1.

[0043] As a preferred technical solution of the present invention, a U-shaped block 130 is fixedly connected to the bottom of the bearing platform 1, a rotating shaft 131 is rotatably connected inside the U-shaped block 130, a connecting rope 135 is wound around the outer surface of the rotating shaft 131, and a threaded connecting rod 133 is fixedly connected to the other end of the connecting rope 135. A connecting block 320 is fixedly connected to the lower surface of the arc-shaped receiving block 370. The end of the threaded connecting rod 133 passes through the interior of the connecting block 320, and a limiting block 134 is threaded through the outer surface of the end of the connecting block 320. One side of the limiting block 134 fits against the other side of the connecting block 320. A motor 132 is installed on the lower surface of the bearing platform 1, and the output shaft of the motor 132 is fixedly connected to the rotating shaft 131.

[0044] During testing, the motor 132 drives the rotating shaft 131 to rotate, and the rotating shaft 131 unwinds a longer length of connecting rope 135 to facilitate subsequent angle adjustment of the fixed end 330 of the electric push rod. After testing is completed, the motor 132 drives the rotating shaft 131 to rotate, causing the rotating shaft 131 to wind up the connecting rope 135. The connecting rope 135 then pulls the arc-shaped receiving block 370 through the connecting block 320 to reset, thereby resetting the electric push rod assembly and facilitating subsequent testing.

[0045] Furthermore, the end of the connecting rope 135 is connected to a threaded connecting rod 133. The threaded connecting rod 133 is passed through the inside of the connecting block 320 and then threadedly connected to the outer surface of the end of the threaded connecting rod 133 by the 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 bearing platform 1, and fixed brackets 110 are fixedly connected to both ends of the rear side of the lower surface of the bearing platform 1.

[0047] Handrail 5 facilitates the movement of the device, and the wheeled bracket 121 improves the ease of movement.

[0048] As a preferred technical solution of the present invention, a central axis 150 is provided on the upper surface of the bearing platform 1, a level 140 is installed on the upper surface of the bearing platform 1, the center line of the lower surface of the level 140 is parallel to the center line of the central axis 150, and the beam position of the laser rangefinder 360 is parallel to the center line of the central axis 150.

[0049] During testing, the entire device is moved to one side of column 2. At this time, the central axis 150 is directly opposite one side of column 2. The bearing platform 1 and column 2 are judged by observing the level 140 to determine whether they are on the same horizontal line. If they are not on the same horizontal line, the screw lift 120 is used for fine adjustment to ensure that they are on the same horizontal line.

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

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