DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a climbing frame machine position load limit warning device, including a base 1, a bearing platform 2, an adjustment component, a detection plate 3, a warning component and a buffer component.

[0026] Preferably, the early warning component includes: a mounting groove 4, an alarm 5, a pressure sensor 6 and a pressure mechanism 7. The mounting groove 4 is opened inside one end of the base 1, and the alarm 5 is fixedly installed at one end of the mounting groove 4. A pressure sensor 6 is connected to one side of the alarm 5 and located at the other end of the mounting groove 4. One end of the pressure sensor 6 is connected to the pressure mechanism 7, and the pressure sensor 6 is connected to the bottom of the detection plate 3 through the pressure mechanism 7.

[0027] Specifically, through the coordinated use of the alarm 5, the pressure sensor 6 and the pressure mechanism 7, the load-bearing platform 2 is first parked on the top of the detection plate 3, and then the items are transported to the inside of the load-bearing platform 2. When the weight of the items exceeds the load-bearing capacity of the climbing frame, the load-bearing platform 2 will squeeze the detection plate 3, and then the bottom of the detection plate 3 will touch the pressure mechanism 7, and then the pressure mechanism 7 will squeeze the pressure sensor 6, so that the pressure sensor 6 receives the pressure signal, and then the pressure sensor 6 converts the pressure signal into an electrical signal to control the alarm 5 to work, so that the device can issue a load limit warning to prevent the device from falling after raising the load-bearing platform 2 to mid-air, thereby improving the safety of workers using the device.

[0028] Preferably, the pressure mechanism 7 includes: a cavity 701 , a first piston 702 , a push rod 703 , a sliding cavity 704 , a second piston 705 , a push rod 706 and a telescopic spring 707 .

[0029] Specifically, the cavity 701 is opened inside the base 1, and the first piston 702 is adapted to be arranged inside the cavity 701. A push rod 703 is fixedly installed on the top of the first piston 702. One end of the push rod 703 passes through the upper end of the cavity 701 and extends to the top of the base 1 to contact the bottom of the detection plate 3. A sliding cavity 704 is opened on one side of the cavity 701 and located inside the base 1. A second piston 705 is adapted to be arranged inside the sliding cavity 704. A push rod 706 is fixedly installed on one side of the second piston 705. One end of the push rod 706 passes through one end of the sliding cavity 704 and extends to the inside of the mounting groove 4 to be connected with one end of the pressure sensor 6. A telescopic spring 707 is arranged on the surface of the push rod 706 and located inside the sliding cavity 704. One end of the telescopic spring 707 is fixedly installed on the inner wall of one end of the sliding cavity 704, and the other end of the telescopic spring 707 is fixedly connected to one side of the second piston 705.

[0030] Specifically, through the coordinated use of the cavity 701, the first piston 702, the push rod 703, the sliding cavity 704, the second piston 705, the push rod 706 and the telescopic spring 707, when the detection plate 3 presses the push rod 703, the first piston 702 moves downward inside the cavity 701 to compress the air inside the cavity 701, and the compressed air presses the second piston 705 inside the sliding cavity 704;

[0031] Then, the second piston 705 is used to push one end of the push rod 706 toward the inside of the installation groove 4, so that one end of the push rod 706 is subjected to a force on the pressure sensor 6. When the detection plate 3 reduces the pressure on the push rod 703, the telescopic spring 707 pushes the second piston 705, allowing the second piston 705 to push the air into the cavity 701, so that the first piston 702 can push the push rod 703 to reset the push rod 703, thereby facilitating an alarm after the load platform 2 is overloaded, reminding the user to reduce the items on the upper end of the load platform 2.

[0032] Preferably, the adjustment assembly includes: a column 8, a slide groove 9, a hydraulic cylinder 10 and a sliding block 11.

[0033] There are four groups of columns 8, which are fixedly installed at the four corners of the top of the base 1 respectively. A slide groove 9 is opened on one side of the four groups of columns 8, and a hydraulic cylinder 10 is fixedly installed at one end inside the four groups of slide grooves 9. Slide blocks 11 are adapted to be arranged inside the four groups of slide grooves 9, and one side of the four groups of slide blocks 11 is fixedly installed at the two ends of both sides of the supporting platform 2 respectively.

[0034] One end of the slider 11 is fixedly connected to the output end of the hydraulic cylinder 10. By adjusting the setting of the component, the support platform 2 can be made to move upward or downward, so that objects can be easily transported to the interior of a high-rise building.

[0035] Preferably, the buffer assembly includes: a fixed groove 12, a damping block 13, a damping rod 14, a damping piston 15 and a damping spring 16, four groups of fixed grooves 12 are respectively opened at the top of the base 1, and the inside of the fixed groove 12 is adapted to be provided with a damping block 13, the top of the damping block 13 is slidably connected with a damping rod 14, and the tops of the four groups of damping rods 14 are respectively fixedly connected to the four corners of the bottom of the detection plate 3.

[0036] The other end of the damping rod 14 is fixedly connected with a damping piston 15 inside the damping block 13 . A damping spring 16 is fixedly installed on the inner wall of the lower end of the damping block 13 . One end of the damping spring 16 is fixedly connected with one end of the damping piston 15 .

[0037] By setting the buffer component, it can play a shock-absorbing role when the bearing platform 2 falls to the top of the detection plate 3, and can also support the detection plate 3 to avoid the contact between the detection plate 3 and the pressure mechanism 7 when the bearing platform 2 is not overloaded, thereby improving the accuracy of the device's load limit warning for the climbing frame machine position.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
