Description

Technical Field

[0001] This utility model belongs to the field of storage tank maintenance technology, and in particular relates to a mobile platform for maintenance devices of horizontal storage tanks. Background Technology

[0002] Horizontal storage tanks are widely used in petroleum, chemical, and warehousing industries. Their top and sidewall valves, instruments, insulation layers, and other equipment require regular inspection and maintenance. Currently, maintenance of these tanks often utilizes mobile lifting platforms or aerial work platforms; however, these methods typically suffer from the following technical drawbacks: Insufficient anti-overturning capacity poses a significant safety hazard: When the working platform is raised to the top of the tank, the lifting arm and the working platform will form a huge "inverted L-shaped" structure with the base, generating a significant overturning moment. This moment will cause the front end of the base to tend to lift upward. Traditional bases rely solely on their own weight and wheel brakes to resist overturning, resulting in poor stability and making it extremely easy for the entire equipment to overturn, leading to a major safety accident.

[0003] Poor support stability affects operational accuracy and safety: After most mobile bases are in place, they are still supported by elastic components such as tires. The compression deformation of the tires and uneven ground can cause slight shaking and settling of the entire work platform. This not only affects the work comfort and accuracy of maintenance personnel, but this unstable support state also further exacerbates the risk of overturning.

[0004] The process of fixing and moving is cumbersome and inefficient: In order to enhance stability, some improvement solutions use spiral legs or pads, but this method requires operators to manually adjust them one by one. The process is cumbersome, time-consuming, and requires a high level of experience from the operators. It is difficult to quickly achieve accurate leveling and reliable fixing, which reduces the overall efficiency of maintenance work. Therefore, there is an urgent need in this field for a mobile platform for horizontal storage tank maintenance that can simultaneously solve the three major challenges of anti-tipping safety, support stability, and ease of operation. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile platform for maintenance devices of horizontal storage tanks. By mechanically interlocking the anti-tilting edge at the front end with the anti-tilting beam at the bottom of the tank pre-embedded in the ground, the overturning moment caused by the "inverted L-shaped" structure is fundamentally solved, rather than relying solely on the weight of the equipment to resist it. At the same time, the cooperation between the electromagnet and the steel plate wire embedded in the bottom of the tank provides a strong downward suction force, further resisting the tendency of the front end to lift up. This constructs a multi-layered, active and passive anti-tilting safety guarantee system, which is extremely safe and improves stability.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a mobile platform for maintenance of horizontal storage tanks, including a vehicle body, a tank bottom steel plate line installed on the ground below the horizontal storage tank, and a tank bottom anti-tilting beam installed on the ground below the horizontal storage tank. The vehicle body is equipped with wheels on both the front and rear sides of its sides, and an anti-tilt edge is integrally provided on the lower front part of the vehicle body. The vehicle body is provided with a lifting platform mounting position on the rear top side, and hydraulic feet are fixed at both corners of the rear end of the vehicle body. The front side of the bottom of the vehicle body is provided with a groove that is misaligned with the wheel body and the anti-tilt edge. The groove is a rectangular groove structure with an open bottom. A set of front oil cylinders is fixed on the top of the vehicle body. A lifting platform is slidably connected in the groove. An electromagnet is fixed on the bottom surface of the lifting platform. The ends of the telescopic rods of the two front oil cylinders are fixed to the top of the lifting platform. The anti-tilting beam at the bottom of the tank is a C-shaped beam structure, and the steel plate line at the bottom of the tank is composed of several linearly arranged steel plates embedded in the ground. When the anti-tilting clearance of the vehicle body is set in the groove of the anti-tilting beam at the bottom of the tank, the electromagnet is located directly above the steel plate line at the bottom of the tank.

[0007] Furthermore, the hydraulic foot includes a rear hydraulic cylinder, which is vertically installed at the rear end of the vehicle body. The telescopic rod of the rear hydraulic cylinder passes through the vehicle body and is fixed with a foot plate.

[0008] Furthermore, a hydraulic pump station is provided inside the vehicle body, and both the rear and front cylinders are connected to the hydraulic pump station through pipelines and valve groups.

[0009] Furthermore, when the front hydraulic cylinder is in the retracted state, the bottom surface of the electromagnet is flush with the bottom surface of the vehicle body, the stroke of the front hydraulic cylinder is greater than the distance between the vehicle body and the ground, and the thickness of the lifting platform is greater than the distance between the vehicle body and the ground.

[0010] Furthermore, the two wheels at the rear of the vehicle body are large running wheels, the two wheels at the front of the vehicle body are large omnidirectional wheels, and wheel wells that mate with the wheels are provided on both sides of the vehicle body.

[0011] Furthermore, the top of the vehicle body is provided with a set of inverted T-shaped through-holes that communicate with the groove. The front oil cylinder is installed in the large-diameter section of the through-hole, and the telescopic end of the front oil cylinder passes through the small-diameter section of the through-hole.

[0012] This utility model has the following beneficial effects: 1. This utility model fundamentally solves the overturning moment caused by the "inverted L-shaped" structure by mechanically interlocking the anti-tilting edge at the front end with the anti-tilting beam pre-embedded in the ground at the bottom of the tank. When the overturning moment is generated, the anti-tilting edge is firmly hooked by the upper lip of the anti-tilting beam at the bottom of the tank, directly transmitting the overturning force to the ground foundation, rather than relying solely on the weight of the equipment itself. At the same time, the cooperation between the electromagnet and the steel plate wire pre-embedded in the bottom of the tank provides a strong downward suction force, further resisting the tendency of the front end to lift up, completely eliminating any slight horizontal movement of the moving platform (such as sliding or shaking), achieving the effect of "welding" to the ground, and constructing a multi-layered, active and passive anti-tilting safety guarantee system with extremely high safety and improved stability.

[0013] 2. This utility model, by designing hydraulic feet at the rear end, can stably transfer the weight of the equipment to the ground, forming a stable support surface together with the front end mechanism. This greatly lowers the center of gravity, improves the overall anti-overturning ability, and further enhances the load capacity and stability. Moreover, by bearing the main load with hydraulic feet, the swaying and settling problems caused by the load-bearing of elastic components such as tires are completely avoided. This provides an almost absolutely stable base for the aerial work platform, ensuring that the support feet do not compress or deform after bearing the load, thereby ensuring the verticality of the lift column and the stability of the work platform.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
