Description

Technical Field

[0001] The utility model belongs to the technical field of boiler installation, and specifically relates to a boiler installation frame. Background Art

[0002] A boiler is an energy conversion device that is mainly used to convert chemical energy or electrical energy in fuel into thermal energy, thereby generating steam, high-temperature water or organic heat carrier with a certain amount of thermal energy;

[0003] For example, the Chinese patent for a gas boiler installation and connection frame with the authorization announcement CN 218821026 U includes a base, an arc block, and several fixed blocks are equidistantly fixed on one side of the base. A slide groove is provided on the top surface of the base, and a second slide groove is provided in the middle of the top surface of the base. The slide groove is movably connected to the clamping block, and a connecting plate is provided on the back of the clamping block. The gas boiler installation and connection frame is provided with slide grooves on both sides of the top surface of the base, and the gas boiler is placed between the arc block and the fixed block by utilizing the symmetry between the arc surface of the arc block and the arc surface of the fixed block. The arc block and the fixed block clamp the gas boiler firmly, thereby avoiding the use of bolts to fix the gas boiler. When the gas boiler is damaged, the arc block can be moved to separate the gas boiler from the installation and connection frame, and workers do not need to remove the bolts one by one, thereby saving time for removing the bolts and improving the efficiency of separating the gas boiler from the installation and connection frame.

[0004] During the use of the fixed boiler as described above, the base will inevitably vibrate, which can easily cause the threaded rod to rotate, thereby loosening the arc block, reducing the stability and firmness of the filter fixation, and may also cause potential risks to the overall safety performance and operating efficiency of the boiler. Utility Model Content

[0005] The utility model aims to provide a boiler mounting bracket, which can limit the reversal of the screw rod, avoid the loosening of the clamping plate when the screw rod is reversed, and thus improve the stability and firmness of the boiler fixation.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A boiler mounting bracket comprises a base, the base is provided with a movable groove, a screw rod is rotatably installed inside the movable groove, a movable block is screwed on the outer wall of the screw rod, a fixed tube is fixed on one side of the base corresponding to the screw rod, and one end of the screw rod passes through the fixed tube, a sleeve is provided on the outer wall of the fixed tube, a first sliding groove is provided on the inner wall of the sleeve, a first sliding block slidably connected to the first sliding groove is fixed on the outer wall of the fixed tube, an annular ratchet is fixed on one end of the sleeve, a positioning rod matched with the annular ratchet is fixed on the outer wall of the screw rod, a limiting plate is fixed on one end of the sleeve, a spring is fixed on one side of the limiting plate, and the spring is sleeved on the outer wall of the fixed tube.

[0008] Furthermore, a push block is provided on the top of the limiting plate.

[0009] Furthermore, a limiting rod is rotatably mounted on the outer wall of the base and located on one side of the spring, and a placing rod for limiting the limiting rod is provided on the outer wall of the base.

[0010] Furthermore, a counterweight block is arranged on the bottom end of the limiting rod.

[0011] Furthermore, a base is fixed on the outer wall of the base and located below the sleeve, and a rotating motor is arranged on the outer wall of the base, and an output shaft of the rotating motor is fixed to one end of the screw rod.

[0012] The technical effects achieved by this utility model are:

[0013] The utility model discloses a boiler mounting frame, wherein the annular ratchet is arranged, and when the screw rod rotates forwardly, the positioning rod is driven to rotate. At this time, the pawl on the annular ratchet will not restrict the rotation of the screw rod. After the boiler is fixed, after the screw rod stops rotating, the annular ratchet cooperates with the positioning rod to limit the reverse rotation of the screw rod, thereby preventing the clamping plate from loosening when the screw rod is reversed, thereby improving the stability and firmness of the boiler fixation.
