Description

Technical Field

[0001] This utility model relates to the field of civil defense engineering technology, specifically to an auxiliary device for installing explosion-proof valves in civil defense systems. Background Technology

[0002] The explosion-proof valve installation auxiliary device for civil defense systems can use mechanical structures to assist in the precise alignment of explosion-proof valves with pipes, walls, and other installation positions, avoiding installation deviations caused by human operation errors and ensuring the sealing and coaxiality of valves and interfaces.

[0003] In the prior art, a valve installation angle adjustment device with patent publication number CN208215251U includes an adjustment block, a placement groove on the adjustment block, an installation plate in the placement groove, an adjustment ball in the installation plate, clamping rods threaded on both sides of the adjustment block, steel balls rolled in the installation plate, and a support column fixedly connected to the top of the adjustment ball.

[0004] During use, this device clamps and fixes the valve to the outer wall of the pipeline. When adjusting the angle of the pipeline by controlling the sliding hole and slider, there is a problem with poor adjustment accuracy. Clamping the pipeline from the outer wall may cause the pipeline to deform or scratch the outer wall due to excessive clamping force. Poor adjustment accuracy will cause the valve to still have a slight deviation after being adjusted to the target angle, which may affect the sealing performance of the pipeline system. Utility Model Content

[0013] Furthermore, the outer surface of the slider makes sliding contact with the inner wall of the guide block;

[0014] The turntable, through the slider, drives the arc plate to rotate, enabling the arc plate to drive the explosion-proof valve body to rotate synchronously in the vertical direction.

[0019] Furthermore, the fixing block is fixedly sleeved on the outer surface of the support column.

[0020] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0021] This utility model, by setting a positioning mechanism, not only supports the explosion-proof valve body from the inner wall during installation, avoiding the problem of deformation or scratches caused by clamping the outer wall, but also prevents slight deviations from the explosion-proof valve body after adjustment to the target angle by cooperating with the rotating and flipping components.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example: An auxiliary device for installing explosion-proof valves in a civil defense system, as shown in the attached document. Figure 1 -Appendix Figure 5 ,include,

[0032] 100 bearing frame;

[0033] Explosion-proof valve body 300 is located on the outside of the support frame 100;

[0034] The positioning mechanism 200 includes an inner support assembly 210 for supporting the explosion-proof valve body 300 from the inside, a rotating assembly 220 for controlling the explosion-proof valve body 300 to rotate in the horizontal and vertical directions, and a flipping assembly 230 for controlling the explosion-proof valve body 300 to adjust the angle.

[0035] The inner support assembly 210, the rotating assembly 220, and the flipping assembly 230 are all located directly above the support frame 100;

[0036] The inner support assembly 210 includes a mounting frame 211 located directly above the support frame 100, a first cylinder 212 adapted to be installed on the outside of the mounting frame 211, a connecting column 213 fixedly installed on the output end of the first cylinder 212 by bearings, and a plurality of wedges 214 arranged in a circumferential array on the outer surface of the connecting column 213.

[0037] Specifically, the inner support assembly 210 also includes a sliding sleeve 215 slidably sleeved on the outer surface of the wedge block 214, an arc plate 216 fixedly connected to the outside of the sliding sleeve 215 and used to support the inner wall of the explosion-proof valve body 300, a slider 217 fixedly connected to the outer end face of the arc plate 216, a turntable 218 fixedly mounted on the outer surface of the mounting bracket 211 by bearings, and a guide block 219 fixedly connected to the outer surface of the turntable 218 and used in conjunction with the slider 217.

[0038] It should be noted that when the first cylinder 212 drives the connecting column 213 to move axially, the connecting column 213 can drive the wedge block 214 to squeeze the sliding sleeve 215, causing the sliding sleeve 215 to drive the arc plate 216 to expand or contract radially, thereby causing the arc plate 216 to be tightly or loosely attached to the inner wall of the explosion-proof valve body 300. When the first motor 221 drives the gear 222 to rotate, the gear 222 can drive the gear disk 223 and the turntable 218 to rotate synchronously. Then, through the cooperation of the turntable 218 and the guide block 219, the slider 217 and the arc plate 216 are driven to rotate around the axis of the turntable 218, thereby causing the arc plate 216 to drive the explosion-proof valve body 300 to rotate synchronously in the vertical direction.

[0039] Furthermore, the outer surface of the slider 217 slides in contact with the inner wall of the guide block 219;

[0040] The turntable 218 drives the arc plate 216 to rotate via the slider 217, which enables the arc plate 216 to drive the explosion-proof valve body 300 to rotate synchronously in the vertical direction.

[0041] Preferably, the rotating assembly 220 includes a first motor 221 adapted to be mounted on the outer surface of the mounting bracket 211, a gear 222 fixedly connected to the output end of the first motor 221 via a coupling, and a gear disk 223 meshing with the outer surface of the gear 222 and used to drive the turntable 218 to rotate.

[0042] It should be noted that the rotating assembly 220 also includes a second motor 224 adapted to be installed on the top of the support frame 100, a rotating rod 225 fixedly connected to the output end of the second motor 224 via a coupling, a support sleeve 226 fixedly connected to the other end of the rotating rod 225, a support column 227 rotatably connected to the inner surface of the support sleeve 226, and a connecting block 228 fixedly connected to the outer end face of the support column 227 and used in conjunction with the mounting frame 211.

[0043] Furthermore, the gear plate 223 is fixedly sleeved on the outer surface of the turntable 218, and the mounting bracket 211 is fixedly installed on the top of the connecting block 228.

[0044] It should be explained that when the second motor 224 drives the support column 227 to rotate through the rotating rod 225 and the support sleeve 226, it can drive the connecting block 228 and the mounting bracket 211 to rotate synchronously through the support column 227. In turn, the mounting bracket 211 drives the support sleeve 226 to rotate through the connecting block 228 and the support column 227, and then the support sleeve 226 drives the explosion-proof valve body 300 to rotate horizontally.

[0045] Specifically, the flipping assembly 230 includes a second cylinder 231 adapted to be installed on the top of the support frame 100, an annular guide rail 232 fixedly connected to the output end of the second cylinder 231, a force-receiving ball 233 movably connected to the inner wall of the annular guide rail 232, a swing rod 234 integrally formed on the outer surface of the force-receiving ball 233, and a fixing block 235 fixedly connected to the other end of the swing rod 234 and used in conjunction with the support column 227.

[0046] Preferably, the fixing block 235 is fixedly sleeved on the outer surface of the support column 227.

[0047] When the second cylinder 231 drives the annular guide rail 232 to move vertically, the annular guide rail 232 can squeeze the force ball 233, thereby causing the force ball 233 to drive the swing rod 234 and the fixed block 235 to rotate around the support column 227. Then, the support column 227 drives the mounting frame 211 to flip through the connecting block 228, thereby driving the explosion-proof valve body 300 to flip synchronously with the mounting frame 211.

[0048] When using,

[0049] Place the support frame 100 and the explosion-proof valve body 300 in a suitable installation position, so that the explosion-proof valve body 300 is fitted onto the outside of the arc plate 216.

[0050] The first cylinder 212 is started to drive the connecting column 213 to move axially, so that the connecting column 213 drives the wedge block 214 to squeeze the sliding sleeve 215, and then the sliding sleeve 215 drives the arc plate 216 to expand radially until the arc plate 216 is tightly attached to the inner wall of the explosion-proof valve body 300, thus completing the internal support and fixation of the valve, and then the first cylinder 212 is controlled to stop moving.

[0051] When the explosion-proof valve body 300 needs to be rotated vertically: the first motor 221 is started to drive the gear 222 to rotate, and then through the cooperation of the gear 222 and the gear plate 223, the turntable 218 is driven to rotate synchronously, so that the turntable 218 drives the slider 217, the arc plate 216 and the explosion-proof valve body 300 to rotate around the turntable 218 through the guide block 219, so as to achieve the effect of controlling the explosion-proof valve body 300 to rotate vertically;

[0052] When the explosion-proof valve body 300 needs to be adjusted by horizontal rotation: start the second motor 224 to drive the rotating rod 225, the support sleeve 226 and the support column 227 to rotate synchronously, and then drive the connecting block 228 and the mounting bracket 211 to rotate synchronously through the support column 227, thereby driving the support sleeve 226 and the explosion-proof valve body 300 to rotate horizontally;

[0053] When it is necessary to control the explosion-proof valve body 300 to rotate at an angle: the second cylinder 231 is activated to drive the annular guide rail 232 to move vertically. The annular guide rail 232 squeezes the force ball 233, which in turn drives the swing rod 234 and the fixed block 235 to rotate around the support column 227. Then, through the cooperation between the fixed block 235 and the support column 227, the connecting block 228 and the mounting bracket 211 are rotated, so that the explosion-proof valve body 300 rotates synchronously with the mounting bracket 211, thereby achieving the effect of controlling the explosion-proof valve body 300 to complete multi-angle gapless adjustment.

[0054] In summary, by setting up the positioning mechanism 200, not only can the explosion-proof valve body 300 be supported from the inner wall during installation, avoiding the problem of deformation or scratches caused by clamping its outer wall, but also, when controlling the explosion-proof valve body 300 to adjust its angle, the cooperation between the rotating component 220 and the flipping component 230 can prevent slight deviations from the explosion-proof valve body 300 after it has been adjusted to the target angle. This achieves the effect of reducing damage to the explosion-proof valve body 300 during installation while significantly improving installation accuracy.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
