Description

Technical Field

[0001] This utility model relates to the field of elevator installation technology, and in particular to an elevator installation construction platform test frame. Background Technology

[0002] Elevator installation must strictly adhere to correct and reasonable installation procedures, which can generally be divided into three stages: the first stage involves the foundation work in the elevator shaft; the second stage involves the placement and installation of the elevator equipment; and the third stage is commissioning and acceptance. During elevator installation, a construction platform is typically used. This platform can move up and down within the elevator shaft to install elevator components. Before formal installation, the construction platform often needs to be tested and inspected. Since existing test racks are not suitable for construction platforms of different specifications, publication number CN204643419U proposes "a test rack for an elevator installation construction platform." By setting two adjustable-spacing supports, it is suitable for construction platforms of different specifications, allowing for testing of construction platforms of various sizes.

[0003] However, the two supports in this solution do not have a movable structure at the bottom, which makes it inconvenient when the test frame needs to be moved. In view of the above reasons, this application proposes an elevator installation construction platform test frame. Utility Model Content

[0021] Example like Figure 1-5As shown, the present invention proposes an elevator installation construction platform test frame, which includes two supports 1. The bottom of each of the two supports 1 is provided with a base 2 for installation. The bottom of the base 2 is provided with a storage groove 3 for storage. One side of the storage groove 3 is provided with an installation cavity 4. The same moving component 5 for improving the flexibility of the support 1 is provided in the storage groove 3 and the installation cavity 4. The upper part of the two supports 1 is provided with a pressure-bearing pipe 7 for installing the construction platform. The movable component 5 includes a rectangular block 501 for installation, a horizontal plate 502 for positioning, and a blocking block 503. The horizontal plate 502 is movably connected to the mounting cavity 4. A positioning groove is provided on the top inner wall of the mounting cavity 4. A positioning block is fixedly provided on the top of the horizontal plate 502, and the positioning block and the positioning groove are movably connected. A plurality of springs 506 are fixedly provided on one side of the horizontal plate 502. The ends of the multiple springs 506 away from the horizontal plate 502 are fixedly connected to the inner wall of the mounting cavity 4. The front of both the horizontal plate 502 and the base 2 are provided with positioning holes with the same inner diameter. The positioning hole on the front of the base 2 communicates with the mounting cavity 4. A threaded rod for positioning is movably provided in the positioning hole on the base 2. The threaded rod and two through-holes are connected to the positioning groove. The hole matching, threaded rod and cross plate 502 are set to limit the universal wheel 505 when it is folded and released. The bottom of the rectangular block 501 is provided with a universal wheel 505 to improve the flexibility of the equipment. The bottom of the rectangular block 501 is provided with a rectangular groove. The top of the universal wheel 505 is fixedly provided with a connecting block 504. Both sides of the connecting block 504 are fixedly provided with a rotating shaft 507. Both rotating shafts 507 are movably connected to the inner wall of the rectangular groove. The inner wall of the rectangular groove is provided with a mounting hole. A coil spring 508 is fixedly provided in the mounting hole. The coil spring 508 applies force to the rotating shaft 507 to assist the universal wheel 505 to reset. The inner ring of the coil spring 508 is fixedly sleeved on the rotating shaft 507. Mounting plates 6 are fixedly installed on the top of both brackets 1. A shock-absorbing structure 8 is provided between the mounting plates 6 and the pressure-bearing pipe 7. The shock-absorbing structure 8 includes two mounting seats 801. Two dampers 802 are fixedly installed inside the mounting seats 801. Springs 803 are sleeved on the dampers 802. The top of the two dampers 802 is fixedly installed on the same top plate 804. The top of the two top plates 804 is fixedly installed on the same placement seat 805. The top of the placement seat 805 is fixedly installed on the positioning frame 806.

[0022] In this embodiment, when the bracket 1 needs to be moved, first remove the bolts fixing the base 2, then lift the bracket 1 using the equipment, and then pull the horizontal plate 502 towards the spring 506. After the horizontal plate 502 is fully retracted into the mounting cavity 4, pull the caster 505 downwards. The caster 505 rotates 90 degrees around the pivot 507, and the connecting block 504 engages with the blocking block 503. Then, release the horizontal plate 502, and the spring 506 pushes the horizontal plate 502 back to its original position. One side of the horizontal plate 502 engages with the connecting block 504. Then, rotate the threaded rod clockwise to insert it into the through hole of the horizontal plate 502, thus positioning the horizontal plate 502. The cooperation between the horizontal plate 502 and the blocking block 503 can limit the connection block 504, making it perpendicular to the base 2 and preventing the caster 505 from tilting. Then, by pushing the bracket 1, the bracket 1 can be transferred. After being transferred to the designated location, the threaded rod is removed, and the horizontal plate 502 is pulled to one side. When the horizontal plate 502 is fully retracted into the storage cavity 4, the coil spring 508 causes the connecting block 504 to return to its original position. At this time, the universal wheel 505 is folded and retracted into the storage cavity 3. Then, the base 2 is fixed to the ground with bolts. The foldable universal wheel 505 not only improves the flexibility of the equipment, but also allows for quick storage after movement, thereby ensuring the fit between the base 2 and the ground and improving the stability of the equipment. During the impact test, the damper 802 and the spring 803 can effectively absorb and buffer the vibration, reduce the impact of vibration on the overall structure of the test frame, reduce the risk of component loosening caused by vibration, and also reduce noise interference during the test, making the test data more accurate and reliable.

[0023] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
