Description

Technical Field

[0001] This utility model relates to the field of experimental auxiliary equipment technology, and in particular to an expandable container test chamber platform. Background Technology

[0002] When conducting tests on standard or smaller test chambers, test platforms are installed on both sides of the chamber for operators to stand on and adjust the test equipment. Conventional test chamber platforms are typically designed based on the location of the steel columns and the dimensions of the hydraulic presses with different strokes on those columns. The span between the two platforms used for testing is generally between 4 and 5 meters. Due to the large span between the platforms, the distance between the test chamber and the platform in the middle is also relatively large. Therefore, a ladder is usually installed at one corner of the conventional test chamber platform. After adjusting the equipment on one side, the operator needs to climb down the ladder on that side, walk to the other side platform, and then climb up again to perform the operation. This process of climbing up and down the ladder is labor-intensive, time-consuming, and leads to low work efficiency.

[0003] Therefore, there is an urgent need for a test chamber platform that allows operators to stand while conveniently crossing the boxes to the opposite platform for debugging operations, saving the process of climbing ladders and improving work efficiency. Utility Model Content

The translational tracks extend horizontally along a first direction to provide a sliding path for the rollers.

[0008] Preferably, a locking mechanism is provided between the translation track and the extension platform to fix the position of the extension platform.

[0009] Preferably, the locking mechanism comprises a positioning pin, a positioning shaft sleeve fixed on the expansion platform, a plurality of positioning holes equidistantly arranged on the translation rail in the first direction, and the positioning pin can pass through the positioning shaft sleeve and be inserted into the corresponding positioning hole when the positioning shaft sleeve and the positioning hole are coaxial.

[0010] Preferably, the positioning shaft sleeve is arranged on the side of the connecting part away from the extension part.

[0011] Preferably, the translation rail is provided with a limiting end plate at both ends in the first direction, for limiting the sliding range of the roller.

[0028] As Figures 1-3 shown, the expansion platform 2 comprises a connecting part 21 and an extension 22 arranged along the first direction, the connecting part 21 is connected with the pulley mechanism 3, and the expansion platform 2 is erected above the fixed platform 1 through the supporting action of the pulley mechanism 3, the extension 22 moves to the outside of the fixed platform 1 when the expansion platform 2 moves horizontally, and the operator stands on it. Guardrails 23 are arranged on both sides of the expansion platform 2 to provide safety protection for the operator and improve the safety of the platform. The guardrails 23 are arranged on both sides of the expansion platform 2 along a second direction, and the second direction is perpendicular to the first direction. When the operator pushes the expansion platform 2 to move, the operator can apply force by pushing and pulling the guardrails 23, which is convenient to operate and saves manpower.

The roller 32 is internally provided with a bearing, the bearing is sleeved on one end of the pin shaft 34, and the other end of the pin shaft 34 is screwed with a nut 35 for fixing the pin shaft 34 to prevent the roller 32 and the bearing from falling off. A flat spring washer (not marked) is arranged between the support plate 33 and the nut 35 to increase the friction to prevent the nut from rotating. In a specific embodiment, the support plate 33 and the connecting portion 21 are locked and connected by three groups of bolts 36 arranged in a triangular structure to improve the connection strength between the support plate 33 and the connecting portion 21.

[0031] As Figures 1-3 shown, in this specific embodiment, two groups of rollers 32 are correspondingly provided and spaced apart in the translation track 31 to improve the connection stability between the connecting portion and the fixed platform. The more rollers 32 and support plates 33 are provided, the higher the connection stability is to ensure that when the operator stands on the extension portion 22 outside the fixed platform 1, the rollers 32 and the corresponding support plates 33 limited in the translation track 31 have a pulling force on the extension platform 2 to prevent the extension platform 2 from falling.

[0032] As Figures 1-3 shown, the translation track 31 and the extension platform 2 are provided with a locking mechanism 4 for fixing the position of the extension platform 2.
