[0002] Explosion-proof analytical hut is a new technology that became popular in the world in the mid-1980s. It integrates the combination, set, installation and application of industrial online instruments, and was first widely used in oil refining and chemical enterprises.

[0003] In order to facilitate the later movement of the existing positive pressure explosion-proof cabin, rollers are generally installed directly on the bottom of the positive pressure explosion-proof cabin for movement. However, when used later, the support of the rollers greatly reduces the stability of the positive pressure explosion-proof cabin.

[0004] Therefore, it is necessary to provide a new positive pressure explosion-proof cabin to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a positive pressure explosion-proof room.

[0008] An adjustment component, wherein the adjustment component is provided with several groups and respectively located in each mounting tube, the adjustment component comprises a mounting plate, an airbag, a fixed inner tube, a fixed outer tube and a shock absorbing spring, the mounting plate is fixedly mounted on the inner top of the mounting tube, a fixedly connected airbag is provided on the bottom side of the mounting tube, a shock absorbing spring is provided inside the airbag on the bottom side of the mounting plate, a fixedly connected fixed inner tube is provided outside the airbag on the bottom side of the mounting plate, and a slidably connected fixed outer tube is sleeved on the outside of the fixed inner tube.

[0009] Preferably, a fixedly connected air pump is provided on the inner top of the explosion-proof cabin body, and a connecting pipe is provided at the output end of the air pump, and the connecting pipe passes through the explosion-proof cabin body, the mounting tube and the mounting plate respectively to communicate with the interior of the airbag.

[0010] Preferably, a plurality of interconnected exhaust pipes are provided on the outer wall of the connecting pipe, and a solenoid valve is provided on the outer wall of each exhaust pipe.

[0011] Preferably, through grooves are provided at the four corners of the outer wall of the explosion-proof room body, the inner wall of each through groove is fixedly connected to the outer wall of each corresponding mounting tube, and the inner wall of each mounting tube is provided with a plurality of evenly distributed guide grooves.

[0012] Preferably, the bottom sides of the airbag, the shock absorbing spring and the fixed outer cylinder inside the same mounting cylinder are all fixedly connected to the top side of the same support plate, and a universal wheel is provided at the bottom of the support plate.

[0013] Preferably, a fixedly connected guide block is provided at a position of the outer wall of the support plate corresponding to each guide groove, and the outer wall of each guide block is slidably connected to the inner wall of the corresponding guide groove.

[0014] Compared with the related art, the positive pressure explosion-proof cabin provided by the utility model has the following beneficial effects:

[0015] 1. The utility model is provided with an adjustment component. When the staff moves the explosion-proof cabin body to the desired position, the solenoid valve can be opened. At this time, the gas inside the airbag in the adjustment component will be smoothly discharged outward through the exhaust pipe. At this time, the tension of the shock-absorbing spring in the adjustment component and the gravity of the explosion-proof cabin body itself squeeze the universal wheel, so that the universal wheel can be smoothly stored in the installation tube, so that the bottom side of the explosion-proof cabin body can be smoothly contacted with the ground, and the universal wheel is not needed to support the explosion-proof cabin body, so that the later installation and placement of the explosion-proof cabin body can be more stable.

Later in the process of transporting the device, the staff can open the adjustment component to extend the universal wheel from the inside of the installation tube, and then make the universal wheel contact the transport vehicle. At this time, the vibration generated by the transport vehicle during transportation will first be transmitted to the shock-absorbing spring through the universal wheel. At this time, the shock-absorbing spring will absorb the vibration transmitted from the outside to a certain extent, thereby reducing the probability of damage to the internal parts of the explosion-proof room body due to vibration. When the external crane lifts the explosion-proof room body from the transport vehicle, the universal wheel will first contact the ground. Therefore, when the universal wheel contacts the ground, the shock-absorbing spring can also reduce the probability of damage to the internal parts of the explosion-proof room body due to the vibration generated by the impact when the explosion-proof room body contacts the ground.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0027] See also Figures 1 to 7 The utility model provides a positive pressure explosion-proof cabin, which comprises an explosion-proof cabin body 1 and an adjustment component 3. The four corners of the outer wall of the explosion-proof cabin body 1 are provided with mounting tubes 2.

[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 The adjusting assembly 3 is provided with several groups and respectively located in each mounting tube 2. The adjusting assembly 3 includes a mounting plate 31, an airbag 32, a fixed inner tube 33, a fixed outer tube 331 and a shock absorbing spring 34. The mounting plate 31 is fixedly mounted on the inner top of the mounting tube 2. The bottom side of the mounting tube 2 is provided with a fixedly connected airbag 32. The inside of the airbag 32 on the bottom side of the mounting plate 31 is provided with a shock absorbing spring 34. The outside of the airbag 32 on the bottom side of the mounting plate 31 is provided with a fixedly connected fixed inner tube 33, and the outside of the fixed inner tube 33 is provided with a slidingly connected fixed outer tube 331.

[0029] It should be noted that: later, when the staff moves the explosion-proof cabin body 1 to the desired position, the solenoid valve 4c can be opened. At this time, the gas inside the airbag 32 in the adjustment component 3 will be smoothly discharged outward through the exhaust pipe 4b. At this time, the tension of the shock-absorbing spring 34 in the adjustment component 3 and the gravity of the explosion-proof cabin body 1 itself squeeze the universal wheel 5a, so that the universal wheel 5a can be smoothly stored in the installation tube 2, so that the bottom side of the explosion-proof cabin body 1 can be smoothly contacted with the ground, and the universal wheel 5a is not needed to support the explosion-proof cabin body 1, so that the later installation and placement of the explosion-proof cabin body 1 can be more stable;

[0030] By sleeved a slidably connected fixed outer cylinder 331 on the outer wall of the fixed cylinder, when the airbag 32 is inflated, the fixed outer cylinder 331 and the fixed inner cylinder 33 sleeved on the outside of the airbag 32 can smoothly limit the airbag 32 in the horizontal direction. As the airbag 32 gradually expands, the inflated airbag 32 can smoothly drive the fixed outer cylinder 331 to move downward through the bottom support plate 5, so that the airbag 32 can be smoothly inflated in the vertical direction.

[0031] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 A fixedly connected air pump 4 is provided at the inner top of the explosion-proof cabin body 1, and a connecting pipe 4a is provided at the output end of the air pump 4, and the connecting pipe 4a passes through the explosion-proof cabin body 1, the mounting tube 2 and the mounting plate 31 respectively and is connected with the inside of the airbag 32, and a plurality of connected exhaust pipes 4b are provided on the outer wall of the connecting pipe 4a, and a solenoid valve 4c is provided on the outer wall of each exhaust pipe 4b.

[0032] It should be noted that: by setting the air pump 4, when the adjustment component 3 needs to be extended later, the staff can control the air pump 4 to work, and the working air pump 4 can smoothly introduce the gas into the airbag 32 in the adjustment component 3 through the connecting pipe 4a, so as to smoothly expand the airbag 32;

[0033] At the same time, when it is necessary to control the adjustment component 3 to shrink, the solenoid valve 4c on the outer wall of the exhaust pipe 4b can be opened. At this time, the gas inside the airbag 32 can flow smoothly into the exhaust pipe 4b through the connecting pipe 4a, and then can flow out smoothly through the exhaust pipe 4b, so that the airbag 32 can shrink smoothly.

[0034] In the embodiments of the present invention, please refer to Figure 1 , Figure 6 and Figure 7 The four corners of the outer wall of the explosion-proof cabin body 1 are provided with through grooves 1a, the inner wall of each through groove 1a is fixedly connected to the outer wall of each corresponding mounting tube 2, and the inner wall of each mounting tube 2 is provided with a plurality of evenly distributed guide grooves 2a.

[0035] It should be noted that: by providing through grooves 1a at the four corners of the explosion-proof cabin body 1, the installation tube 2 can be smoothly embedded in the bottom of the explosion-proof cabin body 1 and connected to the explosion-proof cabin body 1, so that the universal wheel 5a inside the installation tube 2 can smoothly pass through the explosion-proof cabin body 1 and abut against the ground later.

[0036] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The bottom sides of the airbag 32, the shock absorbing spring 34 and the fixed outer tube 331 inside the same mounting tube 2 are fixedly connected to the top side of the same support plate 5, and a universal wheel 5a is provided at the bottom of the support plate 5.

[0037] It should be noted that: by integrating the support plate 5 with the airbag 32, the shock-absorbing spring 34 and the fixed outer tube 331, when the airbag 32 expands or the shock-absorbing spring 34 contracts due to its own tension, the support can be smoothly driven to move up and down, and then the universal wheel 5a at the bottom of the support plate 5 can be smoothly slid inside the mounting tube 2.

[0038] In the embodiments of the present invention, please refer to Figure 5 and Figure 6 A fixedly connected guide block 5c is provided at a position corresponding to the outer wall of the support plate 5 and each guide groove 2a, and the outer wall of each guide block 5c is slidably connected to the inner wall of the corresponding guide groove 2a.

[0039] It should be noted that: by slidably connecting the guide block 5c with the guide groove 2a, when the adjustment component 3 drives the support plate 5 to slide later, the guide block 5c can slide smoothly inside the guide groove 2a, thereby making the sliding of the support plate 5 more stable.

[0040] The working principle of the positive pressure explosion-proof cabin provided by the utility model is as follows:

[0041] Later, during the transportation of the device, the staff can first control the air pump 4 to work, and the working air pump 4 can smoothly introduce gas into the air bag 32 through the connecting pipe 4a to inflate the air bag 32;

[0042] At this time, the inflated airbag 32 can smoothly drive the universal wheel 5a at the bottom of the support plate 5 to move downward inside the installation tube 2, and can smoothly make the universal wheel 5a slide out from the installation tube 2, so that the universal wheel 5a contacts the transport vehicle.

[0043] At this time, the vibration generated by the transport vehicle during transportation will first be transmitted to the shock absorbing spring 34 through the universal wheel 5a. At this time, the shock absorbing spring 34 will absorb the vibration transmitted from the outside to a certain extent, thereby reducing the probability of damage to the internal components of the explosion-proof room body 1 due to vibration;

[0044] When the external crane lifts the explosion-proof cabin body 1 from the transport vehicle, the universal wheel 5a will first contact the ground. Therefore, when the universal wheel 5a contacts the ground, the shock absorbing spring 34 can also reduce the probability of damage to the internal components of the explosion-proof cabin body 1 caused by the vibration generated by the impact when the explosion-proof cabin body 1 contacts the ground.

[0045] When the staff moves the explosion-proof cabin body 1 to the desired position, the solenoid valve 4c can be opened. At this time, the gas inside the airbag 32 in the adjustment component 3 will be smoothly discharged outward through the exhaust pipe 4b. At this time, the tension of the shock-absorbing spring 34 in the adjustment component 3 and the gravity of the explosion-proof cabin body 1 itself squeeze the universal wheel 5a, so that the universal wheel 5a can be smoothly stored in the installation tube 2, so that the bottom side of the explosion-proof cabin body 1 can be smoothly contacted with the ground, and the universal wheel 5a is not needed to support the explosion-proof cabin body 1, so that the later installation and placement of the explosion-proof cabin body 1 can be more stable.

[0046] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
