Description

Technical Field

[0001] The utility model relates to the technical field of maintenance platforms, in particular to an adjustable maintenance platform. Background Art

[0002] A thermal power plant, also known as a thermal power plant, is a factory that uses combustibles as fuel to produce electricity. In order to maintain the normal operation of a thermal power plant, it is necessary to conduct regular maintenance on various equipment in the thermal power plant. However, the equipment in a thermal power plant is large in size and requires a platform to be built for maintenance.

[0003] For example, Chinese patent application No. 202020042586.9 discloses a thermal power plant maintenance platform with a safety protection function. By setting a scissor-type connecting rod and cooperating with a hydraulic push rod, the support plate can be automatically lifted and lowered, which is convenient for maintenance personnel to inspect equipment at different heights. By setting hydraulic legs, the safety of the entire platform can be improved to avoid tilting and tipping. By setting a fence, the safety of maintenance personnel can be protected to avoid falling. At the same time, by setting a fence and rubber pads, objects on the surface of the support plate can be prevented from falling. By setting rubber pads, the anti-slip effect can be improved while reducing the chance of electric shock for maintenance personnel.

[0004] In the above scheme, due to the influence of the on-site environment, the platform of the maintenance platform cannot completely reach the equipment that needs to be maintained, so the operator needs to climb over the guardrail and cross the space distance between the platform and the maintenance equipment, which can easily cause the operator to fall from the maintenance platform, posing a major safety hazard. In order to solve the above problems, we designed an adjustable maintenance platform. Utility Model Content

[0005] The utility model provides an adjustable maintenance platform to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An adjustable maintenance platform comprises a base, wherein the upper side wall of the base is fixedly connected to a plurality of hydraulic cylinders, the telescopic ends of the plurality of hydraulic cylinders are fixedly connected to the maintenance platform, the base is provided with a limiting structure, the upper side wall of the maintenance platform is fixedly connected to four fixed plates, the maintenance platform is connected to two oppositely arranged extension plates through a plurality of hinges, two iron chains are fixedly connected to the side wall of each of the extension plates, one end of the two iron chains are respectively fixedly connected to the side walls of two adjacent fixed plates, a plurality of grooves are provided on the bottom side wall of the base, a plurality of threaded rods are threadedly connected to the base, each of the threaded rods passes through the groove and the side wall of the base, and an anti-sliding block is fixedly connected to the bottom end of the threaded rod.

[0008] Preferably, the limiting structure includes four limiting plates, and the four limiting plates are fixedly connected to the upper side wall of the base. The inner sides of the four limiting plates are provided with limiting grooves, and the four limiting grooves are slidably connected with limiting sliders, and the four limiting sliders are fixedly connected to the side walls of the inspection platform.

[0009] Preferably, locking hooks are connected to the side walls of both sides of the extension plate via a rotating shaft, and iron rings are fixedly connected to the side walls of the plurality of fixed plates.

[0010] Preferably, a plurality of movable wheels are fixedly connected to the bottom side walls of the base, and the plurality of movable wheels are self-locking universal wheels.

[0011] Preferably, a group of protection rods are fixedly connected to the opposite side walls of every two of the fixing plates, and a through groove is formed on one group of the protection rods.

[0012] Preferably, the upper ends of the plurality of threaded rods are fixedly connected with a rotating handle.

[0013] Preferably, a storage box is provided on the upper side wall of the base, and the storage box is located between the plurality of hydraulic cylinders.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The extension plate can be laid flat by hinges and iron chains, so that maintenance personnel can transition to the designated maintenance equipment side through the extension plate without the need for operators to climb over the platform, which improves the safety of operators. After use, the extension plate can be fixed to the side of the fixed plate by locking hooks and iron rings, which is convenient and quick;

[0016] The anti-slip block can be controlled to move up and down through the threaded rod, so that the anti-slip block is against the ground, increasing the anti-slip effect of the base. When the operator moves on it or is collided, the base is prevented from moving left and right due to force, thereby increasing the stability of the base.
