[0026] Embodiment 1 Reference Figure 1as well as Figure 2 A mobile protective bracket includes a support mechanism 1 and a support platform 2. The support platform 2 is arranged on the support mechanism 1 to provide support for the construction of operators. The support mechanism 1 includes a vertical truss 11. The vertical truss 11 is fixed with a protective plate 13. A plurality of first connecting seats 12 are arranged on both sides of the vertical truss 11. The plurality of first connecting seats 12 are laid along the height direction of the vertical truss 11. The first connecting seats 12 are used to connect with the support platform 2. The first connecting seats 12 can be connected with the vertical truss 11 in a pre-embedded manner. The first connecting seats 12 can also be a part of the vertical truss 11.

[0027] The supporting platform 2 includes a platform body 21, and a second connecting seat 22 is fixedly arranged on one side of the platform body 21 close to the supporting mechanism 1. The number and position of the second connecting seat 22 correspond one-to-one to the first connecting seat 12. A fastening mechanism 3 is arranged between the first connecting seat 12 and the second connecting seat 22. Through the fastening mechanism 3, the platform body 21 and the vertical truss 11 can be reinforced and the internal structure can be protected to ensure the stability and service life of the protective bracket.

[0028] Reference Figure 3 , Figure 4 as well as Figure 5 The fastening mechanism 3 includes a connecting component 31 and a tightening component 32. The connecting component 31 is used to connect the first connecting seat 12 and the second connecting seat 22. The tightening component 32 acts on the connecting component 31 to prevent loosening. Specifically, the connecting component 31 includes a connecting stud 311 installed on the first connecting seat 12 and the second connecting seat 22. The connecting stud 311 passes through the first connecting seat 12 to the second connecting seat 22. The connecting stud 311 is provided with a locking nut 312, and the locking nut 312 is tightened against the second connecting seat 22. At the same time, the connecting component 31 also includes a first vibration-damping pad 313 and a second vibration-damping pad 314. The first vibration-damping pad 313 is arranged between the connecting stud 311 and the first connecting seat 12, and the second vibration-damping pad 314 is arranged between the first connecting seat 12 and the second connecting seat 22. By setting the connecting assembly 31 in this way, the first connecting seat 12 and the second connecting seat 22 can be connected through the connecting stud 311. At the same time, the vibration-damping pad can effectively increase the connection strength between the first connecting seat 12 and the second connecting seat 22, thereby increasing the stability and safety of the protective bracket.

[0029] Reference Figure 5 as well as Figure 6The tightening assembly 32 includes a support seat 321 fixedly arranged on the second connecting seat 22, and a tightening spring piece 322 is embedded in the support seat 321, and the tightening spring piece 322 faces the locking nut 312 and abuts against the locking nut 312. Specifically, the support seat 321 has an installation cavity, and a plurality of positioning columns 3211 are arranged in the installation cavity; the tightening spring piece 322 includes a first spring piece and a second spring piece, and the first spring piece and the second spring piece are relatively arranged and embedded in the plurality of positioning columns 3211. The tightening spring piece 322 can be positioned and installed by the positioning columns 3211, and the tightening spring piece 322 applies an elastic force to the locking nut 312 to prevent the locking nut 312 from loosening. In addition, the tightening assembly 32 also includes a tightening spring ring 323, which is arranged between the tightening spring piece 322 and the locking nut 312 to increase the connection strength between the tightening spring piece 322 and the locking nut 312.

[0030] In order to further improve the connection strength between the pressing assembly 32 and the connecting assembly 31 and to provide protection, the fastening mechanism 3 further includes a protection assembly 33, which includes a telescopic rod 331 disposed on the second connecting seat 22, and a pressing slider 332 disposed on the telescopic rod 331. The pressing slider 332 faces the locking nut 312 and is sleeved and installed on the connecting stud 311, and a spring is disposed between the pressing slider 332 and the second connecting seat 22. In this embodiment, the telescopic rod 331 is driven by a cylinder, and the second connecting seat 22 is provided with a slide groove that matches the pressing slider 332. The pressing slider 332 is cross-shaped and is slidably connected to the slide groove. When the locking nut 312 is locked, the telescopic rod 331 is extended under the drive of the cylinder to drive the locking slider 332 to move along the slide groove, thereby moving towards the direction close to the locking nut 312, and finally the locking slider 332 contacts and abuts against the locking nut 312. At this time, the locking slider 332 applies a large thrust to one side of the locking nut 312. Under the action of this thrust, the locking spring piece 322 will also apply the same reverse thrust to the other side of the locking nut 312. The locking nut 312 can remain stable for a long time under the forces on both sides to achieve an anti-loosening effect, thereby improving the connection reliability and stability of the first connecting seat 12 and the second connecting seat 22.

[0031] In addition, the pressing slider 332 is also provided with a protective telescopic plate 333, which is located above the second connecting seat 22. When the pressing slider 332 is pushed by the telescopic rod 331, the protective telescopic plate 333 will be extended as the pressing slider 332 moves, and finally close the upper end of the second connecting seat 22 to form a nearly closed state, thereby preventing dust or other debris from entering and contaminating the connecting stud 311 and the locking nut 312, reducing blockage or rust, and extending the service life of the connecting parts.

[0032] Reference Figure 7 , Figure 8 as well as Fig. 9 In order to increase the buffering capacity of the support platform 2, a buffer mechanism 4 is provided in the platform body 21, and the buffer mechanism 4 includes a buffer support assembly 41 and a buffer assembly 42 provided on the buffer support assembly 41. Specifically, a support plate 23 is provided above the platform body 21, and the buffer support assembly 41 includes a buffer support 411, a buffer bracket 412 provided on the buffer support 411, and a buffer block 413. The buffer bracket 412 is located in the middle of the platform body 21, and the buffer bracket 412 is used to cooperate with the buffer support 411 for limiting and cooperate with the buffer assembly 42 for buffering.

[0033] One end of the buffer bracket 412 is connected to the support plate 23, and the other end of the buffer bracket 412 is connected to the bottom of the platform body 21. In this embodiment, the buffer bracket 412 includes a first connection block 4121 provided on the support plate 23 and a second connection block 4122 provided on the platform body 21. A first connecting rod 4123 and a second connecting rod 4124 are hinged between the first connecting block 4121 and the second connecting block 4122. A sliding block 4125 is rotatably connected at the connection between the first connecting rod 4123 and the second connecting rod 4124, and the sliding block 4125 is slidably connected to the buffer support 411. When the support plate 23 is affected by vibration, it will move up and down. At this time, the buffer bracket 412 will perform a corresponding action, so that the sliding block 4125 moves left and right along the length direction of the buffer support 411. Due to the limit of the buffer support 411, the buffer bracket 412 will support the support plate 23 during this process, thereby reducing the vibration amplitude of the support plate 23.

[0034] The buffer block 413 includes a main buffer block 4131 disposed on the buffer support 411, and the main buffer block 4131 is provided with an upper auxiliary buffer block 4132 and a lower auxiliary buffer block 4133. The upper auxiliary buffer block 4132 is disposed in contact with the support plate 23, and the lower auxiliary buffer block 4133 is disposed in contact with the platform body 21. In order to cooperate with the installation of the buffer block 413, corresponding holes are provided on the top and bottom of the buffer support 411, and the main buffer block 4131 is located between the two holes. The upper auxiliary buffer block 4132 is slidably connected to the buffer support 411 through the holes and abuts against the main buffer block 4131, and the lower auxiliary buffer block 4133 is slidably connected to the buffer support 411 through the holes and abuts against the main buffer block 4131. When the support plate 23 is affected by vibration, it will move up and down. At this time, the buffer block 413 will perform corresponding actions. The upper auxiliary buffer block 4132 and the lower auxiliary buffer block 4133 will press the main buffer block 4131, and the pressed main buffer block 4131 will deform and cooperate with the buffer assembly 42.

[0035] Reference Figure 8 as well as Fig. 9The buffer assembly 42 includes a plurality of auxiliary cylinders 421 disposed on the buffer support 411 and an auxiliary push rod 422 matched with the main buffer block 4131. The auxiliary cylinder 421 includes a cylinder 4211 and an auxiliary slide rod 4212 slidably connected to the cylinder 4211. The auxiliary slide rod 4212 has a pressure plate sleeved on the cylinder 4211, and the auxiliary slide rod 4212 is sleeved with a buffer spring. The cylinder 4211 has a cavity, and the size of the pressure plate corresponds to the cylinder 4211 to close the cavity of the cylinder 4211. When the support plate 23 vibrates, the pressure plate will be driven to move up and down in the cylinder 4211. In this process, the buffer spring and the air pressure in the cylinder 4211 will further buffer the vibration of the support plate 23, thereby cooperating with the buffer support 412 to further reduce the vibration amplitude of the support plate 23.

[0036] The auxiliary push rod 422 includes a trigger push rod installed on the main buffer block 4131, and an air bag 41311 for driving the trigger push rod is arranged in the main buffer block 4131. The platform body 21 has a protection button, and the trigger push rod contacts or disengages from the protection button (not shown in the figure). In this embodiment, the protection button is used to form a fence on the support platform 2. The support platform 2 includes a plurality of protection plates 24 arranged on the support plate 23, and the protection plates 24 are slidably connected to the support plate 23; when the trigger push rod contacts the protection button, the protection plate 24 will rise.

[0037] When the vibration amplitude of the support plate 23 increases, the upper auxiliary buffer block 4132 and the lower auxiliary buffer block 4133 will press the main buffer block 4131 to deform the airbag 41311 inside it, and the deformed airbag 41311 drives the trigger push rod to contact the protection button, and the protection plate 24 rises from the support plate 23 to form a barrier to the construction environment, thereby blocking and protecting the operators and construction equipment. It can be understood that the protection button can have multiple strokes to form barriers of different ranges, and the specific setting position and number of the protection plate 24 on the support plate 23 can be adjusted according to actual conditions.

[0038] Embodiment 2 Reference Fig.10 A control method for the above-mentioned mobile protective rack comprises the following steps: S1: monitor the real-time status of the support platform and obtain the real-time data of the support platform, including the load and amplitude of the support platform; Specifically, a strain type load sensor and an amplitude sensor are arranged in the platform body. The strain type load sensor can monitor the real-time load data of the platform body, and the amplitude sensor can monitor the real-time amplitude data of the platform body. Real-time data can be obtained by collecting and acquiring data from the two sensors.

[0039] S2: Compare the real-time data with the preset data; The preset data are: the first load range of the support platform is 1-500kg, the first amplitude range is 0-2cm; the second load range of the support platform is 500-800kg, the second amplitude range is 2-5cm; the third load range of the support platform is above 800kg, and the third amplitude range is above 5cm. The real-time data obtained in S1 is compared with the preset data to determine the state of the support platform.

[0040] S3: If the real-time data is higher than the preset data, check whether the support platform has taken protective measures; If the support platform is in the first load range or the first amplitude range, the protection button will not be triggered and the protection plate will not move; if the support platform is in the second load range or the second amplitude range, the protection button will be triggered, part of the protection plate will rise, or the protection plate will rise to a specified height to form a first state enclosure; if the support platform is in the third load range or the third amplitude range, the protection button will be triggered, and the protection plate will rise to form a second state enclosure.

[0041] The highest value of the corresponding range of the real-time load data and the real-time amplitude data in the real-time data is taken for judgment to detect whether the support platform has taken corresponding protection measures at this time. For example, if the real-time load data is in the first load range and the real-time amplitude data is in the second load range, the protection button at this time should be triggered to form the first state enclosure.

[0042] S4: If the supporting platform does not take protective measures, initiate protective measures and record data.

[0043] If the support platform does not take protective measures, the corresponding protective measures will be initiated and the data will be recorded, and the operator will make adjustments later.

[0044] Through the above control method, the protective bracket can have self-inspection and self-protection functions, ensuring that the protection plate can be triggered and raised when the specified conditions are met, thereby protecting the staff and equipment, and further ensuring the safety and stability of the protective bracket.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
