Description

Technical Field

[0001] This utility model relates to the field of load detection technology, specifically to a load detection device for the working bucket of an insulated bucket arm vehicle. Background Technology

[0002] When an aerial work platform is operating at height, workers will stand inside the work bucket with their tools. The load weight of the work bucket varies depending on the work scenario. If the load exceeds the work bucket's capacity, it may cause a serious accident such as a rollover. To ensure operational safety, the load inside the work bucket must be monitored in real time.

[0003] Existing aerial work platform bucket weighing solutions basically involve installing load cells at the bottom of the bucket to directly measure the load. However, the overall weighing mechanism occupies a large space. It is more suitable for non-insulated aerial work platforms, but because the bucket of an insulated aerial work platform is an insulating component, it is not suitable for structural installation under the bucket. Utility Model Content

[0004] The purpose of this invention is to provide a load detection device for the working bucket of an insulated bucket arm vehicle, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a load detection device for an insulated bucket arm truck, comprising: a leveling support mounted on the bucket arm, and further comprising: bushings mounted on both ends of one side of the outer wall of the leveling support, with pins at both ends of the two bushings, a first limiting plate and a second limiting plate respectively mounted on the two bushings via pins, and a lifting frame weldment mounted on one side of the outer wall of the second limiting plate, with the bucket fixed to one end of the lifting frame weldment, and a cantilever beam sensor mounted on one side of the outer wall of the leveling support, the lifting frame weldment contacting the force contact point of the cantilever beam sensor, and a connecting plate fixed to the bottom of the leveling support, a support plate fixed to one side of the outer wall of the connecting plate, and elastic components mounted on both ends of the top outer wall of the support plate, with the same bearing component fixed to the top of the two elastic components, and a press-activated sound device mounted on one end of the top outer wall of the support plate.

[0006] The elastic component includes a fixed tube, a movable rod slidably connected to the inner wall of the fixed tube, and a spring disposed inside the fixed tube.

[0007] The load-bearing assembly includes a load-bearing plate, an insulating pad fixed to the top of the load-bearing plate, and a pressure bar fixed to the bottom of the load-bearing plate.

[0008] The support plate includes two structural plates and a buffer pad sandwiched between the two structural plates.

[0009] The first limiting plate, the second limiting plate, and the two bushings are hinged together to form a parallelogram structure.

[0010] The support plate is equipped with a first triangular reinforcing plate and a second triangular reinforcing plate on its upper and lower outer walls, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model discloses a load detection device for an insulated bucket truck. By contacting the cantilever beam sensor with the lifting frame welded parts, the load inside the bucket can be monitored in real time. This ensures that the insulation performance of the bucket is not affected by the load monitoring structure. When the cantilever beam sensor fails, the bucket falls due to gravity. The gap between the first and second limiting plates becomes zero. After falling a certain distance, the bucket can press on the bearing component, squeezing the elastic component for cushioning. This causes the bottom of the bearing component to press on the press-activated sounder, which then emits an alarm to promptly alert nearby workers, thus enhancing safety.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a load detection device for an insulated bucket arm truck, comprising: a leveling support 1 installed on the bucket arm, and bushings 5 ​​installed at both ends of the outer wall of one side of the leveling support 1, with pins 4 at both ends of the bushings 5. A first limiting plate 7 and a second limiting plate 8 are respectively installed at both ends of the bushings 5 ​​via the pins 4. A lifting frame weldment 2 is installed on one side of the outer wall of the second limiting plate 8. A working bucket 3 is fixed at one end of the lifting frame weldment 2. A cantilever beam sensor 6 is installed on one side of the outer wall of the leveling support 1. The lifting frame weldment 2 contacts the force contact point of the cantilever beam sensor 6. A connecting plate 9 is fixed at the bottom of the leveling support 1. A support plate 10 is fixed on one side of the outer wall of the connecting plate 9. Elastic components 11 are installed at both ends of the top outer wall of the support plate 10. The same bearing component 12 is fixed at the top of the two elastic components 11. A press-activated sound device 13 is installed at one end of the top outer wall of the support plate 10.

[0022] It should be noted that: by contacting the cantilever beam sensor 6 through the lifting frame welded part 2, the load inside the working bucket 3 can be monitored in real time. The cantilever beam sensor 6 is located on the outside of the working bucket, so that the insulation performance of the working bucket 3 is not affected by the load monitoring structure. When the cantilever beam sensor 6 fails, the working bucket 3 falls due to gravity, which drives the second limiting plate 8 to descend, so that the gap between the first limiting plate 7 and the second limiting plate 8 is zero. The protruding parts between the first limiting plate 7 and the second limiting plate 8 are locked together to limit the working bucket 3 from falling, ensuring safety. At the same time, the working bucket 3 falls a certain distance and can press on the bearing component 12, which in turn drives the bearing component 12 to descend, squeezing the elastic component 11, and causing the bottom of the bearing component 12 to press on the press-activated sound device 13. The press-activated sound device 13 emits an alarm to promptly remind the surrounding staff, making it safer.

[0023] In a preferred embodiment, the elastic component 11 includes a fixed tube 1101, a movable rod 1102 slidably connected to the inner wall of the fixed tube 1101, and a spring 1103 disposed inside the fixed tube 1101.

[0024] It should be noted that when the working bucket 3 falls and presses on the bearing component 12, it causes the movable rod 1102 to slide into the fixed tube 1101. The compression spring 1103 can buffer the impact of the falling working bucket 3.

[0025] In a preferred embodiment, the support assembly 12 includes a support plate 1201, an insulating pad 1202 fixed to the top of the support plate 1201, and a pressure bar 1203 fixed to the bottom of the support plate 1201.

[0026] It should be noted that when the working bucket 3 falls and presses on the top of the support plate 1201, the insulation of the working bucket 3 can be ensured by the insulating pad 1202. When the working bucket 3 falls, it causes the support plate 1201 to descend, so that the pressure rod 1203 presses on the press-activated sound device 13, and the press-activated sound device 13 can sound an alarm.

[0027] In a preferred embodiment, the support plate 1201 includes two structural plates 1201-1 and a buffer pad 1201-2 sandwiched between the two structural plates 1201-1.

[0028] It should be noted here that this can improve the buffering effect of the bearing plate 1201.

[0029] Working principle: The load inside the working bucket 3 can be monitored in real time by contacting the cantilever beam sensor 6 through the welded part 2 of the lifting frame. The cantilever beam sensor 6 is located on the outside of the working bucket, so the insulation performance of the working bucket 3 is not affected by the load monitoring structure. When the cantilever beam sensor 6 fails, the working bucket 3 falls due to gravity, causing the second limiting plate 8 to descend. This causes the gap between the first limiting plate 7 and the second limiting plate 8 to return to zero. The protruding parts between the first limiting plate 7 and the second limiting plate 8 then engage to limit the falling of the working bucket 3, ensuring safety. Simultaneously, the working bucket 3 falls a certain distance and presses on the top of the support plate 1201. The insulation pad 1202 ensures the insulation of the working bucket 3. The falling of the working bucket 3 causes the support plate 1201 to descend, which in turn causes the movable rod 1102 to slide into the fixed tube 1101. The compression spring 1103 can buffer the impact of the falling working bucket 3. At the same time, the descent of the support plate 1201 causes the pressure rod 1203 to descend. The pressure rod 1203 presses on the press-activated sound device 13, which can sound an alarm to promptly remind the surrounding staff, making it safer.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
