Description

Technical Field

[0002] Unloading platforms are temporary operating platforms and operating racks often set up at construction sites, generally used for material turnover. They are divided into mobile unloading platforms, floor-standing unloading platforms, cantilevered unloading platforms, etc.

[0003] The bottom of the cantilever unloading platform is made of I-beams, which are anchored by steel wire ropes. Wooden boards or steel plates are laid on the I-beams to form a platform. Under the long-term weight of building materials, I-beams are prone to deformation or even breakage, affecting construction safety. Therefore, it is necessary to monitor the deformation degree of I-beams. The monitoring methods mainly include manual level monitoring method and automated electronic equipment monitoring method. The manual level monitoring method not only has a large workload, but also cannot achieve continuous monitoring and cannot detect danger in time. The automated electronic equipment monitoring method is more expensive, which increases the construction cost. Utility Model Content

[0017] By adopting the above technical solution, under the action of the spring restoring force, the insertion rod is pressed tightly against the insertion hole and the corresponding slot, thereby reducing the possibility of the insertion rod loosening and making the fixation more stable.

[0018] Optionally, one end of the insertion rod close to the second tube body is spherical.

[0019] By adopting the above technical solution, when the insertion rod slides into the slot, it plays a guiding role, making it easier for the insertion rod to slide into the slot.

[0020] Optionally: a wear-resistant layer is provided on one end of the first piston rod close to the I-beam.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] This embodiment: a cantilever unloading platform end deformation monitoring device, referring to Figure 1 and Figure 2 , including: a first piston 2 fixedly connected to the outside of the wall 1 and a second piston 3 fixedly connected to the inside of the wall 1. The first piston 2 includes a first piston cylinder 21 fixedly connected to the outside of the wall 1 and a first piston rod 22 slidably connected to the first piston cylinder 21. The second piston 3 includes a second piston cylinder 31 fixedly connected to the inside of the wall 1 and a second piston rod 32 slidably connected to the second piston cylinder 31.

[0031] The first piston rod 22 is parallel to the second piston rod 32, and is perpendicular to the I-beam 4. The top of the first piston rod 22 abuts against the bottom of the I-beam 4 away from the wall 1. The top of the first piston rod 22 is fixedly connected with a wear-resistant layer 23, which is a wear-resistant rubber pad.

[0032] The first piston cylinder 21 is connected to the second piston cylinder 31 through a connecting pipe 5, one end of the connecting pipe 5 is fixedly connected to the bottom of the first piston cylinder 21, and the other end of the connecting pipe 5 is fixedly connected to the bottom of the second piston cylinder 31. Hydraulic oil is contained in the first piston cylinder 21, the second piston cylinder 31 and the connecting pipe 5. A scale 33 is provided on the second piston cylinder 31, and a liquid level monitoring alarm 34 is installed at a predetermined height on the second piston cylinder 31.

[0033] Under the pressure of the building materials, the I-beam 4 is deformed downward, the first piston rod 22 moves downward, and the second piston rod 32 floats up under the transmission of the hydraulic oil. When the second piston rod 32 floats to a predetermined height, the liquid level monitoring alarm 34 sounds an alarm. Real-time monitoring of the I-beam 4 is achieved, which reduces costs and improves safety.

[0034] Since the first piston rod 22 needs to abut against the end of the I-beam 4, when the length of the I-beam 4 is different, the distance between the first piston 2 and the second piston 3 should also be different. Therefore, in this embodiment, the connecting pipe 5 includes a first tube body 51 fixedly connected to the bottom of the first piston cylinder 21 and a second tube body 52 fixedly connected to the bottom of the second piston cylinder 31.

[0035] The second tube body 52 is slidably connected to the first tube body 51 along the length direction of the first tube body 51. The first tube body 51 is connected to the second tube body 52. ​​The first tube body 51 is provided with a fixing assembly 6 for fixing the second tube body 52. ​​A sealing ring is fixedly connected to the outer side of the end of the second tube body 52, and the sealing ring abuts against the inner wall of the first tube body 51.

[0036] According to the length of the I-beam 4, the distance between the first piston 2 and the second piston 3 is adjusted. During the adjustment, the second tube body 52 is pushed to slide along the length direction of the first tube body 51. After the second tube body 52 slides to a predetermined position, the second tube body 52 is fixed by using the fixing assembly 6. The invention has a wide range of applications and strong practicality.

[0037] The fixing assembly 6 includes a plug hole 61 provided on the first tube body 51, a plug rod 62 is slidably inserted into the plug hole 61, the plug rod 62 is perpendicular to the first tube body 51, and one end of the plug rod 62 close to the second tube body 52 is spherical. Five slots 63 for accommodating the plug rod 62 are provided on the second tube body 52 at equal intervals along the length direction of the second tube body 52.

[0038] In addition, a spring 64 is sleeved on the insertion rod 62, one end of the spring 64 is connected to the insertion rod 62, and the other end of the spring 64 is connected to the first tube body 51. The spring 64 is in a stretched state, and the spring 64 causes the insertion rod 62 to have a tendency to slide toward the second tube body 52.

[0039] Before pushing the second tube body 52, slide the rod 62 out of the slot 63. At this time, the spring 64 is in a stretched state, pushing the second tube body 52 to slide along the first tube body 51. After the second tube body 52 is slid to a predetermined position, the insertion hole 61 is aligned with the corresponding slot 63, and the rod 62 is released. Under the action of the restoring force of the spring 64, the rod 62 rebounds to the insertion hole 61 and the corresponding slot 63, and the second tube body 52 is fixed. The operation is convenient and the fixation is stable.

[0040] The implementation principle of the deformation monitoring device at the end of the cantilever unloading platform of the present application embodiment is as follows: according to the length of the I-beam 4, the spacing between the first piston 2 and the second piston 3 is adjusted. When adjusting, before pushing the second tube body 52, the rod 62 is slid out of the slot 63. At this time, the spring 64 is in a stretched state, pushing the second tube body 52 to slide along the first tube body 51. After the second tube body 52 is slid to a predetermined position, the jack 61 is aligned with the corresponding slot 63, and the rod 62 is released. Under the action of the restoring force of the spring 64, the rod 62 rebounds to the jack 61 and the corresponding slot 63, and the second tube body 52 is fixed. The operation is convenient and the fixation is stable.

[0041] Under the pressure of the building materials, the I-beam 4 is deformed downward, the first piston rod 22 moves downward, and the second piston rod 32 floats up under the transmission of the hydraulic oil. When the second piston rod 32 floats to a predetermined height, the liquid level monitoring alarm 34 sounds an alarm. Real-time monitoring of the I-beam 4 is achieved, which reduces costs and improves safety.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
