Abstract
Description
Technical Field
[0001] This invention relates to the field of special vehicles for field operations, and more specifically to a mobile equipment. Background Technology
[0002] This invention relates to a structural improvement of a special-purpose vehicle for field operations based on the Mengshi chassis. Such vehicles typically use onboard generator sets for power supply. However, due to the significant noise and vibration generated by these generator sets, and the fact that they are mounted on the vehicle, the noise and vibration are transmitted to the vehicle body, affecting personnel working inside. Manual loading and unloading of the generator sets is often used, but this method suffers from drawbacks such as the heavy weight of high-power generators, requiring laborious manual handling, low efficiency, and inconvenience in use and maintenance. Furthermore, issues related to the generator's placement stability and vibration damping need to be addressed.
[0003] In practical engineering, the following problems exist when using automated lifting platforms to accommodate generator sets:
[0004] I. In the existing technology, when placing generator sets on special vehicles, there are problems such as impacts due to the large size and weight of the generator sets, which need to be addressed.
[0005] Second, in existing technologies, after a generator set is placed on a special vehicle, the generator set will shake due to the movement of the vehicle, causing undesirable effects. Common methods include adding guardrails, but the space enclosed by the guardrails takes up a large amount of interior space, and the guardrails need to be of a certain height, which is not conducive to space planning. Moreover, if the guardrails are not completely sealed, the problem of generator set shaking still cannot be solved, which is not conducive to adapting to various models of generator sets and requires special manufacturing.
[0006] Third, in the existing technology of spring buffer columns, the life of the springs cannot be guaranteed when they are subjected to long-term impacts; if it is a hydraulic buffer column of the existing technology, the impact energy is absorbed by damping, but a collision still cannot be avoided when the buffer stroke ends.
[0007] Fourth, in the existing technology, the buffer column has only one collision surface at the end of the buffer stroke, which cannot produce a good positive effect on lifespan and impact.
[0008] Fifth, existing hydraulic buffer columns do not utilize the discharge volume factor, resulting in limited functional development.
[0009] VI. In the existing spring-type buffer column technology, the spring is compressed to the extreme during impact and further bears the impact force, resulting in a significant reduction in lifespan. Summary of the Invention

[0015] The upper cover is connected to the lower wall by an upper rod, and the upper rod, sealing disc, middle rod, upper piston, lower rod, lower piston, and liquid pusher block are connected in sequence from top to bottom; the upper rod passes through the through hole, and in the initial state, the sealing disc abuts against the upper wall; in the supported state, the sealing disc seals the sealing hole, the liquid pusher block enters the lower groove, the lower piston separates the lower cavity from the piston cavity, the lower wall of the upper cover abuts against the upper wall of the column, the diameter of the lower cavity is smaller than the diameter of the piston cavity, and the diameter of the liquid pusher block is smaller than the diameter of the lower piston;
[0016] An electromagnet is provided in the main body, and two legs are provided at the bottom of the main body, with a foot under each leg. Reinforcing ribs are provided between the main body and the feet.
[0017] Preferably, the number of support columns is four.
[0018] Preferably, the number of support frames is two.
[0019] Preferably, in the supported state, the lower surface of the liquid-pushing block abuts against the liquid.
[0020] Preferably, in the supported state, the lower surface of the closed disk abuts against the liquid.
[0021] Preferably, in the initial state, the lower surface of the upper piston abuts against the liquid.
[0022] Preferably, the upper cover includes an upper plate and a peripheral wall.
[0023] Preferably, in the supported state, the spring is completely located within the groove.
[0024] Preferably, the sealing disc can prevent liquid in the piston chamber from entering the upper chamber when sealing the sealing hole.
[0025] Preferably, the detector is used to detect whether an object is supported on the support system.
[0026] The beneficial effects of this invention are:
[0027] I. In response to the first point raised in the background technology, a support with a buffer column is proposed, which can reduce the impact when heavy objects are placed.
[0028] Second, regarding the second point raised in the background technology, an electromagnet element is installed on the support, which can better attract the generator set.
[0029] Thirdly, in response to the third point raised in the background technology, a buffer column with hydraulic buffer and spring buffer coupling is designed. At the end of the buffer stroke, a separate liquid space is isolated by the piston. The liquid is fixed in the liquid space to form a lock. The locked part of the liquid provides a liquid stop, thereby providing an additional locked and relatively fixed liquid impact surface on the basis of the original solid collision. The liquid impact surface has a better protection effect than the solid impact surface.
[0030] Fourthly, in response to the fourth point raised in the background technology, a three-point impact surface is provided. Based on the collision between the cover and the column and the previously mentioned liquid impact surface, a second working mode is optionally provided, which adds a second liquid impact surface. Specifically, a baffle is added to the inner cavity of the column, and a through hole is formed in the middle of the baffle. The through hole cooperates with the second collision part (closed disc) to form a complete seal. When it is necessary to increase the impact surface, liquid in the inner cavity of the column can be added. The contact between the closed disc and the liquid forms two liquid impact surfaces at the end of the buffer stroke to further disperse the impact and improve the protection effect on the parts.
[0031] Fifthly, regarding the fifth point raised in the background technology, as mentioned above, a separate liquid space is isolated by a piston. However, it is conceivable that if a cavity forms a liquid space, and the piston is only positioned above the liquid space for isolation, it will still have to abut against the bottom wall of the column surrounding the cavity, resulting in a solid impact. Therefore, a reduced-diameter pusher block is designed below the piston. The pusher block has a small diameter, which facilitates its entry into the liquid space to push the liquid. When the piston falls, the pusher block first enters the liquid space, pushes out a small portion of the liquid in the liquid space, thereby making room so that a small portion of the lower piston can smoothly enter the liquid space, thus forming a more stable state.
[0032] VI. Regarding the sixth point raised in the background technology, a groove is provided at the upper end of the column to accommodate the spring. When the spring is in its original state, it extends out of the groove. When it is compressed, it enters the groove and is protected by the groove so that it will not be excessively compressed. Based on the above-mentioned measures, a balance is sought among various factors such as spring protection and impact protection. Attached Figure Description
