[0043] Figure 1 The structure diagram of the support device 2 in an embodiment is shown. Figure 3 The structure diagram of the support device 2 in another embodiment is shown. For the convenience of description, the following vertical direction is the up-down direction shown in the figure.

[0044] As shown in Figure 1 , Figure 3 , the utility model provides a kind of storage tank, and the storage tank includes tank roof platform 1 and at least one support device 2. Tank roof platform 1 is located at the top of storage tank. Support device 2 is arranged on tank roof platform 1, and support device 2 is used to install high-altitude instrument 3. The instrument 3 installation height of high-altitude instrument 3 is high, and the instrument 3 in high altitude can be flame detector and combustible gas detector, etc., can be used to monitor whether storage tank is safe operation. At least one support device 2 can be one or more than two, and more than two support devices 2 are arranged at intervals.

[0045] The support device 2 provided by the utility model includes mounting table 22, support frame 21, fixed frame 23 and locking mechanism 24.

[0046] Mounting table 22 and fixed frame 23 are all fixed on tank roof platform 1, and the bottom of support frame 21 is rotatably and / or detachably connected to mounting table 22, so that support frame 21 can be erected on mounting table 22 or laid down to be horizontally located on the top of tank roof platform 1. The top of support frame 21, i.e. the other end of support frame 21 away from its connection to mounting table 22, is used to install instrument 3. Locking mechanism 24 can connect and lock support frame 21 erected on mounting table 22 on fixed frame 23, to realize the positioning of support frame 21. The support device 2 of the utility model can provide convenient installation, maintenance and overhaul space for the instrument 3 installed at high altitude, without the need for high-altitude disassembly, maintenance and overhaul of instrument 3, to reduce the safety hazards caused by high-altitude operation.

[0047] Among them, support frame 21 in vertical state can mean that support frame 21 is erected relative to tank roof platform 1 or even perpendicular to tank roof platform 1. Support frame 21 in horizontal laid-down state can mean that support frame 21 is placed on tank roof platform 1, or support frame 21 is parallel to the top surface of tank roof platform 1, or there can be a certain gap and a certain angle between support frame 21 and tank roof platform 1, etc.

[0048] Actually, the top and bottom of support frame 21 are relative descriptions when support frame 21 is in vertical state. In fact, support frame 21 has axial first end and second end, the first end of support frame 21 is used to connect mounting table 22, and the second end of support frame 21 is used to install instrument 3.

[0049] When the instrument 3 needs to be installed, the staff can first install the instrument 3 at the second end of the support frame 21 when the support frame 21 is in a laid-down state, then turn the first end of the support frame 21 upward relative to the mounting table 22, or detachably mount the first end of the support frame 21 on the mounting table 22, so that the support frame 21 is vertically erected on the mounting table 22 as a whole, and finally lock the support frame 21 on the fixed frame 23 through the locking mechanism 24, at this time the instrument 3 is at the top of the support frame 21, the installation of the instrument 3 is completed, and the installation of the high-altitude instrument 3 is facilitated.

[0050] When the instrument 3 needs to be overhauled, replaced or removed, the locking of the support frame 21 and the fixed frame 23 by the locking mechanism 24 is released, then the bottom of the support frame 21 is turned downward relative to the mounting table 22, or the bottom of the support frame 21 is detached from the mounting table 22, and the support frame 21 is laid down on the tank top platform 1, which facilitates the maintenance and operation of the high-altitude instrument 3 by the staff.

[0051] It should be noted that the bottom of the support frame 21 is rotatably and / or detachably connected to the mounting table 22, which means that the bottom of the support frame 21 can be rotatably connected to the mounting table 22 only, or detachably connected to the mounting table 22 only, or detachably and rotatably connected to the mounting table 22.

[0052] One, two or more than two instruments 3 can be mounted on one support frame 21, and the instrument 3 can be a flame detector, a combustible gas detector or the like, which is specifically set according to the installation requirements.

[0053] Figure 2 For Figure 1 A local enlarged view of the middle A area.

[0054] As shown in Figure 1 , Figure 2 , the support frame 21 comprises a main rod 211 and a cross rod 212 which are connected to each other, the cross rod 212 is rotatably or detachably connected with the mounting table 22, one end of the main rod 211 is fixedly connected with the cross rod 212, and the other end of the main rod 211 is used for mounting the instrument 3; the locking mechanism 24 is configured to lock the main rod 211 and the fixed frame 23. The main rod 211 of the support frame 21 is used for mounting the instrument 3, the cross rod 212 is cross-connected with the main rod 211, and the cross rod 212 is arranged to facilitate the connection with the mounting table 22, so that the support frame 21 as a whole can be mounted on the mounting table 22.

[0055] Specifically, the crossbar 212 is arranged perpendicularly to the main rod 211, and is arranged at one axial end of the main rod 211. The two axial ends of the crossbar 212 extend along the two radial sides of the main rod 211, so that the crossbar 212 and the main rod 211 form a T-shaped rod structure. Alternatively, the crossbar 212 can be arranged at a position close to the axial end of the main rod 211, so that the crossbar 212 and the main rod 211 form a cross-shaped rod structure. In some other embodiments, one axial end of the crossbar 212 can be connected to the main rod 211, and the other axial end of the crossbar 212 can extend outwardly along the radial direction of the main rod 211. The end of the crossbar 212 away from the main rod 211 can be rotatably connected to the mounting table 22, so that the crossbar 212 serves as a rotating shaft of the main rod 211 to realize the swinging of the main rod 211. Alternatively, the end of the crossbar 212 away from the main rod 211 can be detachably connected to the mounting table 22, so that the crossbar 212 can be fixed to or detached from the mounting table 22.

[0056] In the present embodiment, the mounting table 22 includes two bases 221 arranged at intervals on the top surface of the tank top platform 1. The side wall of each base 221 is provided with a mounting hole, and the mounting holes of the two bases 221 are arranged oppositely. The two axial ends of the crossbar 212 are arranged one-to-one through the mounting holes of the two bases 221. The crossbar 212 can rotate in the mounting holes. The support frame 21 can be switched between the vertical state and the horizontal state by rotation. When the support frame 21 is in the vertical state, it does not need to be aligned and installed, which saves time and labor and is convenient for the workers to use and disassemble the instrument 3.

[0057] Specifically, the distance between the two bases 221 is less than the axial dimension of the crossbar 212, so that the crossbar 212 can be fixed after being arranged through the mounting holes of the two bases 221, thereby realizing the installation of the crossbar 212. The base 221 can be an angle steel and be rigidly connected to the tank top platform 1. In the case where the crossbar 212 extends only along one radial side of the main rod 211, the base 221 can be provided with only one, and the end of the crossbar 212 away from the main rod 211 can be arranged through the base 221 and clamped on the base 221 by a limiting structure, so as to avoid the crossbar 212 from falling off.

[0058] Further, in order to further facilitate the maintenance and replacement of the high-altitude instrument 3 and the replacement of the support frame 21, the crossbar 212 is rotatably and detachably connected to the two bases 221.

[0059] Specifically, the mounting holes are machined on the side wall of the base 221 at a suitable height, and the inner diameter of the mounting hole is about 3 mm larger than the outer diameter of the crossbar 212. The worker can first arrange one end of the crossbar 212 obliquely through the mounting hole of one base 221, and the length of the crossbar 212 arranged through the mounting hole can be adjusted to be flat. Then, the crossbar 212 is moved axially to pass through the mounting hole of the other base 221. Subsequently, the position of the crossbar 212 is adjusted, so that the crossbar 212 is stably supported in the two mounting holes.

[0060] Further, the crossbar 212 is provided with at least one positioning pin 213 protruding from the outer wall of the crossbar 212, the positioning pin 213 is located near the base 221 of the crossbar 212, used to limit the axial movement of the crossbar 212, prevent the crossbar 212 from falling off between the two mounting holes. When it is needed to disassemble the crossbar 212 from the base 221, the positioning pin 213 is removed first, and the position of the crossbar 212 is adjusted axially, so that the end of the crossbar 212 can be removed from the mounting hole. In this embodiment, the crossbar 212 is provided with a positioning pin 213 on each side near the two bases 221, further improving the installation stability of the crossbar 212.

[0061] In some other embodiments, the top surface of the mounting table 22 is provided with mounting holes, the bottom of the support frame 21 is inserted into the mounting holes, and is locked on the mounting table 22 and the fixed frame 23 through the detachable locking mechanism 24 such as bolts, pins, clamps, pipe clamps, etc., realizing the detachable connection between the support frame 21 and the mounting table 22. The two bases 221 of the mounting table 22 can be provided with special-shaped holes matching the cross section shape of the crossbar 212, so that the crossbar 212 is positioned after being inserted into the special-shaped hole.

[0062] The height of the support frame 21 in the vertical state needs to meet the installation height of the high-altitude instrument 3, so the height of the support frame 21 is relatively high. In order to ensure the stability of the support frame 21 and improve the installation stability of the instrument 3, further, the fixed frame 23 is fixed on the tank top platform 1, the fixed frame 23 can be arranged side by side with the support frame 21 in the vertical state, so that the locking mechanism 24 can lock the support frame 21 on the fixed frame 23, and then the fixed frame 23 realizes the support of the support frame 21. After the locking mechanism 24 locks the support frame 21 and the fixed frame 23, the support frame 21 and the fixed frame 23 are in close contact with each other, reducing the shaking of the support frame 21.

[0063] Specifically, the fixed frame 23 is a steel structure guardrail frame, improving the stability. The fixed frame 23 can be installed on the tank top platform 1 after the support frame 21 is erected, improving the installation precision and reducing the gap between the support frame 21 and the fixed frame 23 or avoiding the inclination of the support frame 21.

[0064] Further, the height of the fixed frame 23 is at least half of the height of the support frame 21, that is, the height of the fixed frame 23 is at least half of the axial length of the support frame 21, improving the support stability of the fixed frame 23 to the support frame 21.

[0065] The number of the locking mechanism 24 of this embodiment is multiple, the multiple locking mechanisms 24 are arranged in the up-down direction, there are multiple locking connection points between the vertical support frame 21 and the fixed frame 23 in the up-down direction, further improving the positioning stability of the support frame 21.

[0066] Figure 4Structure diagram of locking mechanism 24 for locking support frame 21 and fixing frame 23.

[0067] Further, the locking mechanism 24 comprises a first U-shaped bolt 241 and a first nut 242. The first U-shaped bolt 241 has outer threads on the outer periphery of the opposite ends, and the opposite ends of the first U-shaped bolt 241 pass through the fixing frame 23. The first nut 242 is screwed to the part of the first U-shaped bolt 241 that passes through the fixing frame 23, thereby realizing detachable connection between the first U-shaped bolt 241 and the support frame 21. The first U-shaped bolt 241 and the fixing frame 23 together form a containing space for containing the support frame 21. Specifically, after the support frame 21 is erected, the opening of the first U-shaped bolt 241 is sleeved on the support frame 21, and after the opposite ends of the first U-shaped bolt 241 pass through the fixing frame 23, the first U-shaped bolt 241 is locked by the first nut 242, so that the first U-shaped bolt 241 is fixed on the fixing frame 23. With the continuous engagement of the first nut 242, the support frame 21 and the fixing frame 23 can be pulled closer until they are locked and the shaking of the support frame 21 is reduced. The way of sleeving the support frame 21 on the fixing frame 23 by the first U-shaped bolt 241 ensures the strength of the support frame 21.

[0068] In addition, the locking mechanism 24 can also be realized by a bolt passing through the support frame 21 and the fixing frame 23 in sequence and being locked, thereby realizing detachable locking of the support frame 21 and the fixing frame 23.

[0069] The support device 2 under the embodiment also comprises at least one threading pipe 25, the number of which corresponds to the number of the instruments 3 installed on the support frame 21, and the threading pipe 25 has a through hole in the inside for threading the cable 31 of the instrument 3.

[0070] The threading pipe 25 can be a steel pipe 254 or an explosion-proof flexible pipe 253, which is used to protect the cable 31 of the instrument 3. After the cable 31 of the instrument 3 passes through the threading pipe 25 and the bridge frame 4 in sequence, it finally flows into the junction box 5.

[0071] The threading pipe 25 comprises a plurality of pipe fittings 251 which are axially spliced in sequence by a joint 252. At least one joint 252 is located above the tank top platform 1. In the case that the support frame 21 needs to be rotated relative to the mounting table 22, the joint 252 located above the mounting table 22 can be disconnected first, so that the pipe fittings 251 are separated, avoiding interference between the threading pipe 25 and the tank top platform 1. In the case that the support frame 21 needs to be directly disassembled from the mounting table 22, the joint 252 located above the mounting table 22 can be disconnected first, so that the pipe fittings 251 are separated, facilitating disassembly of the support frame 21.

[0072] In some embodiments, each of the pipe fittings 251 is an explosion-proof flexible pipe 253. Alternatively, each of the pipe fittings 251 is a steel pipe 254. In this embodiment, one of the pipe fittings 251 is an explosion-proof flexible pipe 253, and the rest of the pipe fittings 251 are steel pipes 254. The axial ends of the explosion-proof flexible pipe 253 are connected to the instrument 3 and one of the steel pipes 254 through the union joint 252.

[0073] Figure 5 The structure of the union joint 252 is shown in the figure.

[0074] Referring to Figure 2 and Figure 5 , the union joint 252 includes a first pipe 2521, a second pipe 2522, a nut 2523, and a sealing ring 2524. Between two adjacent pipe fittings 251, the first pipe 2521 is arranged on the end of one of the pipe fittings 251, the second pipe 2522 is arranged on the end of the other pipe fitting 251, and the outer periphery of each of the first pipe 2521 and the second pipe 2522 is provided with external threads. The two adjacent pipe fittings 251 are spliced together so that the first pipe 2521 and the second pipe 2522 sandwich a sealing gasket therebetween. The nut 2523 is pre-assembled on the pipe fitting 251 with the first pipe 2521, and the nut 2523 with internal threads is moved and engaged on the first pipe 2521 and the second pipe 2522 to achieve detachable connection of the two adjacent pipe fittings 251. The nut 2523 and the first pipe 2521 have matching stepped surfaces to prevent the nut 2523 from being detached from the pipe fitting 251 with the first pipe 2521 and to ensure that the first pipe 2521 and the second pipe 2522 can be engaged at the same time.

[0075] Further, the wire pipe 25 includes a laying section and an adjusting section connected in sequence and bent relative to each other. The laying section is located below the tank top platform 1 and extends horizontally. The axial one end of the adjusting section is connected to the adjusting section, the adjusting section passes out of the mounting table 22 upwardly, and the axial other end of the adjusting section is used for connection with the instrument 3. The laying section is located below the mounting table 22 and the tank top platform 1, so that the cable 31 of the instrument 3 can be routed from the bottom of the tank top platform 1 to avoid hindering the work of the workers.

[0076] In this embodiment, at least one union joint 252 is arranged at the part of the adjusting section above the tank top platform 1. The connection position between the laying section and the adjusting section can be connected through an L-shaped pipe structure, and the laying section and the adjusting section can also be spliced by a plurality of pipe fittings 251. When the support frame 21 is in the vertical state, the instrument 3 is supported on the top of the support frame 21, and the cable 31 of the instrument 3 is arranged in the wire pipe 25. At this time, the adjusting section can also be in the vertical state.

[0077] Figure 6 The structure of the locking mechanism 26 for locking the mounting block 28 of the support frame 21 and the wire pipe 25 is shown in the figure.

[0078] Referring to Figure 1 and Figure 6 The support device 2 in the embodiment further comprises a plurality of locking mechanisms 26.

[0079] The locking mechanisms 26 are configured to lock the cable tube 25 and the support frame 21 with each other, and the plurality of locking mechanisms 26 are distributed along the axial extension direction of the cable tube 25. The locking mechanisms 26 can lock the cable tube 25 and the support frame 21 with each other, reduce the shaking of the cable tube 25, and improve the installation stability of the instrument 3. The plurality of locking mechanisms 26 further improve the positioning stability of the cable tube 25. Specifically, the locking mechanisms 26 are connected between the adjusting section and the support frame 21, and the arrangement direction of the plurality of locking mechanisms 26 is consistent with the extension direction of the adjusting section.

[0080] Further, the locking mechanisms 26 are configured to lock the cable tube 25 and the tank top platform 1 with each other, and the plurality of locking mechanisms 26 are distributed along the axial extension direction of the cable tube 25.
