Description

Technical Field

[0001] The invention relates to the technical field of safety protection facilities for vibration test benches, and in particular to a multifunctional safety operation protection platform for a vibration test bench. Background Art

[0002] The vibration test bench is an essential process equipment for most mechanical environmental tests. With the continuous increase in thrust and load of the vibration test bench, the height and volume of the vibration test bench are also increasing. When the test personnel go on the bench to operate, they are prone to fall from heights, which threatens the personal safety of the test personnel. Therefore, the vibration test safety operation platform is a necessary protective measure during the mechanical environmental test. At the same time, it is necessary to consider the disassembly and assembly of the expansion bench, the maintenance of the bench body, the inability to test long and large products, and the blocked aisles on both sides of the product.

[0003] It is used in the design of scaffolding construction platforms in the field of construction. The functions and structures of scaffolding construction platforms in the field of construction vary greatly due to their different application fields, and do not meet the functions of the safety facilities field of vibration test benches.

[0004] At present, test personnel use a small inclined ladder to go up and down the vibration table. There is no operation platform and no protection. The safety risk of test personnel completing the test on the table is relatively high, and relevant protection must be carried out. The existing vibration test table has no safe operation protection platform or only realizes a single function such as going up and down the table. At the same time, the installation of the protection platform does not fully consider the problem of difficulty in repairing the table and inconvenience in the test process. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a vibration test bench safe operation protection platform to solve the potential safety hazards faced by test personnel during vibration test operations and improve test efficiency. At the same time, the platform has the advantages of multi-function and flexible operation.

[0006] In order to solve the above technical problems, one of the purposes of the present invention is to provide a multifunctional vibration test bench safe operation protection platform, comprising:

[0007] A fixed guardrail 1, which is composed of a frame base 11, a guardrail 12, a walkway iron plate 13, a skirting board 14, and a grounding plate 15;

[0008] The expansion frame 5 is composed of an expansion frame support frame 51, an inner circular plate 52, a fixed support bottom plate 53, a support bottom plate 54 and a hanging nut 55;

[0009] The inclined ladder door 4 is composed of an inclined ladder door body 41 and an inclined ladder door U-shaped pin 42;

[0010] The expansion rack 5 is placed in the reserved square hole of the fixed guardrail 1, and the expansion rack 5 is supported by the vibration test bench 6, and is connected to the predetermined threaded holes on both sides of the vibration test bench 6 through the fixed support bottom plate 53. After the connection is completed, the inner circular plate 52 on the upper part of the expansion rack 5 and the walkway iron plate 13 remain horizontal, and together form an operating platform. There is a gap between the expansion rack 5 and the fixed guardrail 1 to prevent the fixed guardrail 1 from generating transmitted vibration during the vibration test bench test; the italic door 4 is fixed to the fixed guardrail 1 by the italic door U-shaped pin 42 to prevent the test personnel from falling from the inclined ladder.

[0011] Furthermore, the protection platform also includes an inclined ladder 2 , which is composed of an inclined ladder frame 21 , a foot pedal 22 , a handrail 23 and a grounding plate 15 .

[0012] Furthermore, the inclined ladder 2 is connected to the fixed guardrail 1 by fasteners, which not only ensures the stability of the inclined ladder 2 and the fixed guardrail 1, but also allows for flexible assembly and disassembly.

[0013] Furthermore, when the test product is long or large in size, which affects the passage of test personnel on both sides, inclined ladders are installed on both sides of the vibration test bench safe operation protection platform to avoid being blocked from passage.

[0014] Furthermore, the expansion frame 5 is provided with four holes and nuts for hoisting, so as to facilitate the disassembly and assembly of the expansion frame.

[0015] Furthermore, the expansion frame 5 is connected to the vibration test bench by fasteners to prevent the expansion frame from being deviated from its original position due to vibration.

[0016] Furthermore, when the extended test bench is not in use, the extension rack is used to fill the area left by removing the extension bench, and the extension rack and the fixed guardrail together form an operating platform; when the extended test bench is in use, the extension rack is removed and moved away from the original area through the lifting hole.

[0017] Furthermore, the protection platform also includes an extension door 3 , which is composed of an extension door body 31 , an extension door U-shaped pin 32 and a fixing pin 33 . The extension door 3 is fixed to the fixed guardrail 1 via the extension door U-shaped pin 32 and the fixing pin 33 .

[0018] Furthermore, when the length of the test product is greater than the length of both sides of the guardrail, the extension door is opened to complete the corresponding test.

[0019] Furthermore, the protection platform also includes a video monitoring system 7 to monitor the test process and the safe operation of personnel.

[0020] Furthermore, the protection platform also includes an automatic door opening and closing motor 8 and a photoelectric sensor 9, which can control the number of operators on the operating platform. When a person passes through the photoelectric sensor 9, the system performs statistical analysis. If there is no overcrowding, the automatic door opening and closing motor 8 is started, the inclined elevator door opens, and the system broadcasts "The current number of people on the platform is X"; if there is an overcrowding, the automatic door opening and closing motor 8 does not move, the inclined elevator door does not move, and the system broadcasts "Overcrowding, please do not enter".

[0021] The above one or more technical solutions of the present invention have at least one or more of the following technical effects:

[0022] The protection platform of the present invention protects test personnel from safety threats and enables them to complete scheduled tests more conveniently and efficiently. At the same time, the platform also has the advantages of being easy to install and operate, safe and firm, and easy to dismantle, and having multiple functions and flexibility.

[0023] Build a safe operating platform and guardrail to prevent people from falling and improve test efficiency. The expansion rack is connected to the vibration test bench with fasteners to prevent the expansion rack from deviating from its original position due to vibration.

[0024] When the extension table is not in use, the extension rack can be used to fill the area left by removing the extension table. When the extension table is in use, the extension rack can be removed and moved away from the original area through the lifting hole. When the length of the test product is greater than the length of both sides of the guardrail, the extension door can be opened to complete the corresponding test. When the test product is long or large in size and affects the passage of test personnel on both sides, the vibration test bench safety operation protection platform is designed with double-sided inclined ladders to avoid this situation.
