[0002] At present, various thermal instruments are generally installed in modern power plants. In order to disassemble, calibrate and reinstall these thermal instruments, mobile devices are generally required to move them.

[0003] In the prior art, there is a mobile protection device for thermal instruments in a power plant with patent announcement number: CN213138824U, which includes a base, a box fixedly connected to the base and an equipment carrying device; the box is a rectangular parallelepiped with an opening on the top; a first protective pad is fixedly connected to each of the two sides of the inner wall of the box, and a clamping plate device is provided at each of the two ends of the inner wall of the box. The beneficial effects of the utility model are: its design is simple, easy to use, and can well protect the thermal instruments carried, effectively improving the transportation efficiency and safety and reliability. However, in the existing mobile protection device for thermal instruments in a power plant, when a worker wants to place the thermal instruments into the box, the worker needs to lift the thermal instruments higher than the height of the box so that the thermal instruments can be placed in the box. Therefore, the existing mobile protection device for thermal instruments in a power plant has the problem of being inconvenient for placing the thermal instruments. For this reason, a protection device is proposed. Utility Model Content

[0004] In view of this, the embodiment of the utility model hopes to provide a protective device to solve or alleviate the technical problems existing in the prior art. By installing a limit frame, the limit frame will no longer limit the two first rotating plates and the second rotating plates after sliding, so that the two first rotating plates and the second rotating plates can be rotated and unfolded. Because the two first rotating plates and the second rotating plates can be rotated and unfolded, the device can be more convenient for placing thermal instruments after being unfolded.

[0005] The technical solution of the utility model embodiment is achieved as follows:

[0006] A protective device comprises a base and four first universal wheels. Two first rotating plates and a second rotating plate are rotatably provided on the upper side of the base, and a sliding frame is slidably provided. Four springs are fixedly installed between the base and the sliding frame. Two limit frames are placed on the top of the two first rotating plates and the second rotating plate. Two support assemblies for supporting the base are fixedly installed on the lower side of the base. The support assemblies comprise guide bars, two sliding bars are slidably provided in the guide bars, and second universal wheels are fixedly installed on the sides of the two sliding bars away from each other. Four pins that penetrate the base and the two guide bars are placed in the base.

[0007] Preferably: a raised portion is provided on the upper side of the base, and the two first rotating plates and the second rotating plate are rotatably arranged on the top of the raised portion; seismic isolation foam plates are fixedly installed on the inner sides of the base, the two first rotating plates and the second rotating plate; the five seismic isolation foam plates are all rectangular structures; the setting of the raised portion makes it difficult for the first rotating plate and the second rotating plate to interfere with the sliding frame during rotation.

[0008] Preferably: four guide rods penetrating the sliding frame are fixedly installed on the upper side of the base, four springs are respectively mounted on the circumference of the four guide rods, the inner side walls of the sliding frame are respectively fitted with the circumference of the two first rotating plates and the second rotating plate, and the installation of the guide rods can guide the sliding frame during the sliding process, thereby making the sliding frame slide more smoothly.

[0009] Preferably: the four first universal wheels are respectively fixedly installed on a corner of the base, the tops of the two first rotating plates and the second rotating plates are provided with notches, the two limit frames are both T-shaped structures, the ends of the two limit frames are both provided with limit ends placed inside the notches, the sides of the two first rotating plates and the second rotating plates that are in contact with each other are both inclined in design, the notches are provided to facilitate the accommodation of the limit ends, so that after the limit frames are placed on the first rotating plate and the second rotating plate, they are not easy to slip.

[0010] Preferably: the four sliding bars are all T-shaped structures, the lower surfaces of the two guide bars are provided with guide grooves corresponding to the sliding bars, and the four sliding bars are provided with multiple circular holes corresponding to the four pins respectively. The beginning of the guide groove can guide the sliding bar during the sliding process, so that the sliding bar can slide more smoothly.

[0011] Preferably: a limiting protrusion is provided on the top of the pin, and four second universal wheels are respectively fixedly installed on the lower surfaces of the four sliding bars; a handle is fixedly installed on one side of one of the second rotating plates, and the top of the handle is a cylindrical structure. The setting of the limiting protrusion makes it difficult for the pin to separate from the base when in use.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] 1. The utility model installs a limit frame so that after the limit frame slides, the two first rotating plates and the second rotating plates are no longer limited, so that the two first rotating plates and the second rotating plates can be rotated and unfolded. Because the two first rotating plates and the second rotating plates can be rotated and unfolded, the device is more convenient for placing thermal instruments after it is unfolded.

[0014] 2. The utility model can drive the four second universal wheels to slide away from each other through the installation of the support assembly, so that after the four second universal wheels slide away from each other, the contact area between the device and the ground can be increased. Because the contact area between the device and the ground is increased, the device is not easy to tip over when transporting thermal instruments.

DETAILED DESCRIPTION

[0022] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an embodiment of the utility model provides a protection device, including: a base 1, four first universal wheels 7, two first rotating plates 2 and a second rotating plate 3 are rotatably provided on the upper side of the base 1, and a sliding frame 4 is slidably provided, four springs 5 ​​are fixedly installed between the base 1 and the sliding frame 4, two limit frames 6 are placed on the top of the two first rotating plates 2 and the second rotating plates 3, two support assemblies 8 for supporting the base 1 are fixedly installed on the lower side of the base 1, the support assembly 8 includes a guide bar 9, two sliding bars 10 are slidably provided in the guide bar 9, and second universal wheels 11 are fixedly installed on the sides of the two sliding bars 10 away from each other, and four pins 12 that penetrate the base 1 and the two guide bars 9 are placed in the base 1.

[0025] In the present embodiment, specifically: a protrusion 101 is provided on the upper side of the base 1, the two first rotating plates 2 and the second rotating plate 3 are rotatably arranged on the top of the protrusion 101, and the inner sides of the base 1, the two first rotating plates 2 and the second rotating plate 3 are fixedly installed with seismic isolation foam plates 13, and the five seismic isolation foam plates 13 are all of rectangular structure. The installation of the seismic isolation foam plates 13 plays a certain vibration absorption role, so that the thermal engineering instrument is not easily damaged by vibration during transportation.

[0026] In this embodiment, specifically: four guide rods 14 penetrating the sliding frame 4 are fixedly installed on the upper side of the base 1, and four springs 5 ​​are respectively sleeved on the circumference of the four guide rods 14. The inner side walls of the sliding frame 4 are respectively in contact with the circumference of the two first rotating plates 2 and the second rotating plate 3. The installation of the springs 5 ​​can push the sliding frame 4 to slide, so that after the sliding frame 4 slides, the two first rotating plates 2 and the second rotating plates 3 can be limited, so that the first rotating plates 2 and the second rotating plates 3 are in a vertical state after being limited, so that the first rotating plates 2 and the second rotating plates 3 can transport the thermal instrument in the vertical state.

[0027] In the present embodiment, specifically: four first universal wheels 7 are respectively fixedly mounted on a corner of the base 1, notches are provided on the tops of the two first rotating plates 2 and the second rotating plates 3, the two limiting frames 6 are both T-shaped structures, and the ends of the two limiting frames 6 are both provided with limiting ends 601 placed inside the notches, and the sides where the two first rotating plates 2 and the second rotating plates 3 are in contact with each other are both inclined. The setting of the limiting frames 6 can limit the two first rotating plates 2 and the second rotating plates 3 in the vertical state, so that the two first rotating plates 2 and the second rotating plates 3 in the vertical state are not easy to rotate and tilt.

[0028] In this embodiment, specifically: the four sliding bars 10 are all T-shaped structures, the lower surfaces of the two guide bars 9 are provided with guide grooves corresponding to the sliding bars 10, and the four sliding bars 10 are provided with multiple circular holes 1001 corresponding to the four pins 12 respectively. The opening of the circular holes 1001 facilitates the insertion of the pins 12 into the sliding bars 10, so that the position of the sliding bars 10 after sliding can be fixed, so that the sliding bars 10 are not easy to slide when the device is in use.

[0029] In this embodiment, specifically: a limiting protrusion 1201 is set on the top of the pin 12, and four second universal wheels 11 are respectively fixedly installed on the lower surfaces of the four sliding bars 10; a handle 15 is fixedly installed on one side of one of the second rotating plates 3, and the top of the handle 15 is a cylindrical structure. The installation of the handle 15 is convenient for workers to push the device to move.

[0030] When the utility model is working: when it is necessary to place the thermal instrument inside the device, the sliding frame 4 is pressed downward at this time, and the sliding frame 4 is pressed to squeeze the spring 5, so that the spring 5 contracts at this time. When the sliding frame 4 slides to the lower side of the two first rotating plates 2 and the second rotating plate 3, the sliding frame 4 no longer limits the first rotating plate 2 and the second rotating plate 3. At this time, the two limiting frames 6 are removed. After the two limiting frames 6 are removed, the two first rotating plates 2 and the second rotating plates 3 are rotated at this time. The two first rotating plates 2 and the second rotating plates 3 are The movable plate 3 is unfolded during the rotation. When the first rotating plate 2 and the second rotating plate 3 are rotated, the height of the device becomes lower. When placing the instrument, the worker does not need to move the instrument to the upper side of the first rotating plate 2 and the second rotating plate 3 and then place the instrument in the base 1. The instrument can be placed inside the base 1 by simply raising the height of the instrument to the height of the unfolded first rotating plate 2 and the second rotating plate 3. Because when the two first rotating plates 2 and the second rotating plates 3 are unfolded, it is more convenient to place the thermal instrument.

[0031] When the instrument is placed, the two first rotating plates 2 and the second rotating plates 3 are rotated to a vertical state, and the force of the pressing spring 5 is released at this time, so that the sliding frame 4 slides, and the sliding frame 4 limits the first rotating plate 2 and the second rotating plate 3 after sliding, so that the first rotating plate 2 and the second rotating plate 3 are not easy to rotate after being limited, and the limiting frame 6 is placed on the top of the first rotating plate 2 and the second rotating plate 3, and the limiting frame 6 limits the first rotating plate 2 and the second rotating plate 3;

[0032] When the instrument is transported, because a large number of instruments are stacked inside the device, the device is prone to tilting and tipping over when it is moved. Therefore, the pin 12 needs to be taken out at this time. When the pin 12 is taken out, the four sliding bars 10 are pulled to slide away from each other. The sliding of the four sliding bars 10 drives the four second universal wheels 11 to slide away from each other. After the four second universal wheels 11 slide away from each other, the contact area between the device and the ground is increased. At this time, the four pins 12 are inserted into the inside of the four sliding bars 10. Because the contact area between the device and the ground is increased, the device is not prone to tilting or tipping over when in use.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
