Description

Technical Field

[0001] The present invention relates to a mechanical device, in particular to a highly reliable lifting system for a multi-layer vertical installation and testing work platform. Background Art

[0002] In the technical field of vertical installation and testing work platforms, the work platform generally requires functions of opening, closing, and lifting, so as to facilitate personnel to approach the product to be tested by means of the work platform. Traditional lifting work platforms generally use hydraulic cylinders to drive, realizing the rising and falling of the work platform. Due to the stroke limitation of the hydraulic cylinder, a hydraulic cylinder needs to be provided for each layer of the work platform. If a large range needs to be lifted or lowered at one time, exceeding the maximum stroke of the hydraulic cylinder itself, the pin shaft between the hydraulic cylinder and the guide rail needs to be repeatedly inserted and pulled out, and the lifting is completed by multiple expansions and contractions of the hydraulic cylinder, which is time-consuming and laborious and brings inconvenience to the operation. Therefore, a highly reliable, large-stroke, and multi-layer platform-sharable lifting system is needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a highly reliable lifting system for a multi-layer vertical installation and testing work platform, which can realize the large-range continuous lifting of the work platform with a single operation, is simple to operate, and has a simple structure.

The power assembly, the first reel, the second reel, the first pulley block, and the second pulley block are all connected to the bracket. The first rope sequentially bypasses the first reel, the first lifting ring, and the first pulley block, and the second rope sequentially bypasses the second reel, the second lifting ring, and the second pulley block. The first lifting ring and the second lifting ring are used to connect the work platform to be lifted or lowered. When the power assembly is started, it drives the first reel and the second reel to rotate forward or backward, so that the first lifting ring and the second lifting ring move upward or downward, and the first reel and the second reel act synchronously.

[0006] Further, the power assembly includes a first motor, a second motor, and a synchronous shaft. The synchronous shaft is connected between the first motor and the second motor, and the synchronous shaft is connected to the first reel and the second reel.

[0008] Further, both the first speed reducer and the second speed reducer are planetary speed reducers.

[0009] Further, the power assembly further includes a first brake and a second brake. The first brake is disposed between the first motor and the first speed reducer, and the second brake is disposed between the second motor and the second speed reducer.

[0010] Further, the power assembly further includes a third brake and a fourth brake. The third brake and the fourth brake respectively brake the first drum and the second drum.

[0011] Further, connection pins are provided on both the first sling and the second sling, and the connection pins are used to connect with the work platform to be lifted.

[0015] Compared with the prior art, the high-reliability lifting system of the multi-layer vertical installation and measurement work platform of the present invention has at least the following beneficial effects:

[0016] In the high-reliability lifting system of the multi-layer vertical installation and measurement work platform of the present invention, since the power assembly drives the first sling and the second sling to move up and down through the first rope and the second rope, and the lengths of the first rope and the second rope can cover the entire working range of the work platform, a large-range continuous lifting of the work platform can be realized with a single operation, the operation is simple, and the problems of the complex lifting system of the traditional vertical installation and measurement work platform and the inability to continuously lift in a large range are solved. At the same time, by connecting the first sling and the second sling with the work platform to be lifted, it is convenient to disassemble, so as to realize the sharing of the multi-layer work platforms of the lifting system, and the system scale is simplified; in addition, two ropes are provided, and when one rope breaks, the other rope can keep the work platform from falling, and the safety is improved.

[0023] As Figure 1 、 Figure 2 、 Figure 3 shown, a highly reliable lifting system for a multi-layer vertical installation and measurement work platform of the present invention includes a power assembly 01, a first drum 21, a second drum 22, a first pulley block 23, a second pulley block 24, a first rope 25, a second rope 26, a first sling 27, a second sling 28, and a bracket 03. The first rope 25 and the second rope 26 are both rigid ropes. In this embodiment, the first rope 25 and the second rope 26 are both made of steel wire ropes. The power assembly 01, the first drum 21, the second drum 22, the first pulley block 23, and the second pulley block 24 are all connected to the bracket 03.

The second rope 26 successively passes around the second drum 22, the second sling 28, and the second pulley block 24. The first sling 27 and the second sling 28 are used to connect the work platform 04 to be lifted. When the power assembly 01 is started, it drives the first drum 21 and the second drum 22 to rotate forward or backward, so that the first sling 27 and the second sling 28 move upward or downward, and the first drum 21 and the second drum 22 act synchronously. Specifically, two guiding cylinders 41 are provided on each work platform 04 to be lifted, and the first sling 27 and the second sling 28 are respectively connected to the two guiding cylinders 41 of a work platform 04 to be lifted. When it is necessary to lift a certain layer of the work platform 04 to be lifted, as Figure 4 、 Figure 5As shown in the figure, taking the example of first lifting and lowering the upper working platform and then the middle working platform, the power assembly 01 drives the first suspension ring 27 and the second suspension ring 28 to be lowered to the guide cylinder 41 of the upper working platform to be lifted and lowered 04, connects with the guide cylinder 41, and then drives the first suspension ring 27 and the second suspension ring 28 to rise to the specified height; when it is necessary to lift and lower the middle working platform, the connection between the guide cylinder 41 of the original working platform and the first suspension ring 27 and the second suspension ring 28 is released, and the first suspension ring 27 and the second suspension ring 28 are driven to be lowered to the guide cylinder 41 of the middle working platform to be lifted and lowered 04, thus completing the switching of the lifting of different working platforms. In the high-reliability lifting system of the multi-layer vertical installation and measurement working platform of the present invention, since the power assembly 01 drives the first suspension ring 27 and the second suspension ring 28 to move up and down through the first rope 25 and the second rope 26, and the lengths of the first rope 25 and the second rope 26 can cover the entire working range of the working platform, the large-range continuous lifting of the working platform can be realized with a single operation, the operation is simple, and the problems of the complex lifting system of the traditional vertical installation and measurement working platform and the inability to continuously lift in a large range are solved. At the same time, by connecting the first suspension ring 27 and the second suspension ring 28 with the working platform to be lifted and lowered 04, it is convenient to disassemble, so as to realize the sharing of the multi-layer working platform of the lifting system and simplify the system scale; in addition, two ropes are set, and when one rope breaks, the other rope can keep the working platform from falling, improving the safety.

[0027] Optionally, the power assembly 01 further includes a first brake 17 and a second brake 18.
