Description

Technical Field

[0001] The invention relates to the technical field of gas pressure regulator installation equipment, and more particularly to an adjustable installation bracket with a protective function for a gas pressure regulator. Background Art

[0002] Gas pressure regulator is commonly known as pressure reducing valve, also called gas pressure regulating valve. It is a device that automatically changes the gas flow through the regulating valve to keep the outlet gas at a specified pressure. It is usually divided into direct-acting type and indirect-acting type. The pressure regulator is a special valve on the gas pipeline. It can keep the downstream pressure stable regardless of the changes in gas flow and upstream pressure. The pressure regulator should be able to: 1. Reduce the upstream pressure to a stable downstream pressure; 2. When the pressure regulator fails, it should be able to limit the downstream pressure to a safe range.

[0003] When installing a gas pressure regulator, a mounting bracket is required to install it, but the existing mounting bracket cannot be conveniently adjusted in length and height, and the gas pressure regulator is heavy, which increases the difficulty of installation and affects the installation efficiency. Summary of the invention

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an adjustable mounting bracket with a protective function for a gas pressure regulator. The length of the mounting plate can be adjusted by a support plate and an extended support plate, thereby effectively increasing the installation area of ​​the mounting plate to meet different usage requirements. The height of the mounting plate can be adjusted by a lifting assembly, which facilitates installation and debugging and effectively reduces the difficulty of installation.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A gas pressure regulator with an adjustable mounting bracket having a protective function comprises a base, a lifting assembly is fixed at the center of the upper surface of the base, the lifting assembly is a cylinder or a hydraulic cylinder, a mounting plate is provided on the upper side of the base, the mounting plate comprises a support plate with a hollow structure inside and two extended support plates plugged into the support plate, a lifting output end of the lifting assembly is fixedly connected to the center of the lower surface of the support plate, an electromagnet is fixed at the center of the support plate, the two extended support plates are respectively arranged on the left and right sides of the electromagnet, a mounting groove is provided on the side of the extended support plate close to the electromagnet, and a bar magnet is fixed inside the mounting groove, the magnetic pole arrangement direction of the electromagnet when energized is opposite to the magnetic pole direction of the bar magnet, an inner support rod is provided at the lower end of the extended support plate away from the support plate, and the inner support rod is slidably connected to the extended support plate through a sliding clamping structure, outer support rods matching the inner support rods are fixed at the left and right ends of the upper surface of the base, the inner support rod is plugged into the outer support rod, and a box-type protective structure is provided on the upper side of the support plate and the extended support plate. When using the mounting bracket, the voltage regulator is mounted on the support plate and the extended support plate, and is protected by a box-type protection structure. Since the extended support plate is plugged into the inside of the support plate, in the initial state, the electromagnet is in a power-off state, and the bar magnet and the iron core of the electromagnet are attracted to each other. When the electromagnet is energized, since the magnetic pole arrangement direction of the electromagnet is opposite to the magnetic pole direction of the bar magnet, a repulsive effect is exerted on the bar magnet, and the extended support plate is ejected from the support plate, and the extended support plate is supported by the inner support rod and the outer support rod, thereby realizing the adjustment of the length of the mounting plate, effectively increasing the installation area of ​​the mounting plate, and meeting different usage requirements. The height of the mounting plate can be adjusted by using a lifting assembly, which is convenient for installation and debugging, and effectively reduces the difficulty of installation.

[0009] Furthermore, a limiting plate is fixed to one end of the extended support plate close to the electromagnet, and limiting protrusions are integrally formed on the inner walls of both ends of the support plate. The width of the limiting plate is greater than the inner spacing of the limiting protrusions, and the limiting plate is a rubber plate. By setting the limiting plate and the limiting protrusion, the extended support plate can be limited to prevent the extended support plate from moving out of the support plate, thereby ensuring stability. The limiting plate is a rubber plate, which can effectively buffer when the extended support plate collides with the electromagnet.

[0010] Furthermore, a push-pull handle is fixed on the side wall of one end of the extended support plate outside the support plate, and an anti-slip pattern is cut on the outer wall of the push-pull handle. The push-pull handle is used to facilitate pushing and pulling of the extended support plate, and is convenient for operation.

[0011] Furthermore, the sliding clamping structure includes a clamping slot provided on the lower surface of the extended support plate along its length direction and a clamping slider fixed to the top of the inner support rod, the clamping slider matches the clamping slot, and the clamping slider is clamped inside the clamping slot, the clamping slider is a T-shaped block, and the clamping slot is a T-shaped slot. The clamping slider and the clamping slot of the T-shaped structure are clamped to realize the sliding clamping connection between the inner support rod and the extended support plate, so as to realize a firm connection without affecting the sliding.

[0012] Furthermore, a spherical groove is provided on the side wall where the clamping slider contacts the clamping slot, a steel ball is embedded in the spherical groove, and the steel ball contacts the inner wall of the clamping slot. By providing the spherical groove and the steel ball, the friction resistance of the clamping slider when sliding in the clamping slot can be greatly reduced.

[0013] Furthermore, the box-type protection structure includes a vertical plate fixed on the extended support plate, and the tops and front and rear sides of the two vertical plates are fixed with telescopic horizontal plates, and the telescopic horizontal plates include two relatively arranged outer plates, and the opposite ends of the two outer plates are provided with strip grooves, and the inner plates are inserted in the two strip grooves, and the inner side walls of the outer plates are pasted with a sealing layer. The vertical plates on both sides and the telescopic horizontal plates form a box-type structure, which effectively protects the voltage regulator, and the telescopic horizontal plates on the front and rear sides and the upper side include outer plates and inner plates, which can be telescopically adjusted in conjunction with the extended support plate and the support plate to meet the use requirements of different lengths, and the provided sealing layer can provide sealing protection to prevent dust from entering.

[0014] Furthermore, the outer plate and the inner plate at the front side are provided with corresponding openings, and an inspection door is installed at the opening. The inspection door is provided to facilitate the inspection and operation of the voltage regulator inside the box-type protective structure.

[0015] Furthermore, two openings are provided on the vertical plate, and dust-proof heat dissipation boxes matching the openings are provided in the openings. A plurality of ventilation ducts are provided on the inner sides of the left and right end faces of the dust-proof heat dissipation boxes. The ventilation ducts on both sides are arranged in a staggered manner, and the ventilation ducts on the left and the ventilation ducts on the right are arranged symmetrically. An induced draft fan is fixed on the outer side of the dust-proof heat dissipation box on the upper side of the vertical plates on both sides. By arranging four dust-proof heat dissipation boxes and induced draft fans on the vertical plates on both sides, the voltage regulator inside the box-type protective structure can be effectively cooled and dust-proofed, and the induced draft fans on both sides are located at the top, so that a cross airflow can be formed inside the box-type protective structure, effectively improving the heat dissipation effect and ensuring the working environment inside the box-type protective structure.

[0016] Furthermore, the ventilation duct includes an air outlet section, a middle section and an air inlet section, the air outlet section and the air inlet section are arranged horizontally, the middle section is arranged vertically, and the inner wall of the middle section is frosted, a dust collection hole opening downward is provided on the ventilation duct, and the dust collection hole is located below the middle section, a coarse filter is installed at the end of the air inlet section, a fine filter is installed at the end of the air outlet section, and a dust filter layer is vertically provided at the center of the dustproof heat dissipation box. By setting a dustproof heat dissipation box that is symmetrically arranged on the left and right, the wind flow can flow inside and outside the box-type protective structure through the dustproof heat dissipation box, and at the same time, when the air passes through the ventilation duct through the middle section, the dust hits the inner wall of the middle section, and then falls from the dust collection hole to the bottom of the dustproof heat dissipation box. The frosted inner wall of the middle section can also effectively adhere to the dust, and the dust filter layer arranged inside can also be dustproof, and multiple dustproof mechanisms are used to ensure the dustproof effect.

[0017] Furthermore, the dust filter layer includes gauze filter layers on both sides and a non-woven filter layer located in the middle of the gauze filter layer. The gauze filter layer and the non-woven filter layer are combined to filter dust, which further improves the dustproof effect.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) This solution adjusts the length of the mounting plate through the support plate and the extended support plate, effectively increasing the installation area of ​​the mounting plate to meet different usage requirements. The height of the mounting plate can be adjusted using the lifting assembly, which facilitates installation and debugging and effectively reduces the difficulty of installation.

[0021] (2) By setting a limit plate and a limit protrusion, the extended support plate can be limited to prevent the extended support plate from moving out of the support plate and ensure stability. The limit plate is a rubber plate that can effectively buffer when the extended support plate collides with the electromagnet.

[0022] (3) The push-pull handle facilitates pushing and pulling of the expansion support plate, making operation easier.

[0023] (4) The sliding connection between the inner support rod and the extended support plate is realized by using the T-shaped structure of the clamping slide block and the clamping groove to achieve a firm connection without affecting the sliding.

[0024] (5) By providing the spherical groove and the steel ball, the friction resistance encountered by the snap-in slide block when sliding in the snap-in slide groove can be greatly reduced.

[0025] (6) The vertical plates and telescopic horizontal plates on both sides form a box-type structure, which effectively protects the voltage regulator. The telescopic horizontal plates on the front, rear and upper sides include outer plates and inner plates, which can be telescopically adjusted in conjunction with the extended support plates and support plates to meet the use requirements of different lengths. The sealing layer can provide sealing protection to prevent dust from entering.

[0026] (7) By providing an inspection door, it is convenient to inspect and operate the voltage regulator inside the box-type protection structure.

[0027] (8) By arranging four dust-proof heat dissipation boxes and induced draft fans on the vertical plates on both sides, the voltage regulator inside the box-type protective structure can be effectively cooled and dust-proofed, and the induced draft fans on both sides are located at the top, so that cross airflow can be formed inside the box-type protective structure, effectively improving the heat dissipation effect and ensuring the working environment inside the box-type protective structure.

[0028] (9) By setting up a dustproof heat dissipation box that is symmetrical on the left and right, the wind can flow through the dustproof heat dissipation box inside and outside the box-type protective structure. At the same time, when the air passes through the ventilation duct through the middle section, the dust hits the inner wall of the middle section and then falls from the dust collection hole to the bottom of the dustproof heat dissipation box. The inner wall of the middle section is frosted to effectively adhere to the dust. The dust filter layer set inside can also prevent dust. Multiple dust prevention mechanisms are used to ensure the dust prevention effect.

[0029] (10) A combination of a gauze filter layer and a non-woven filter layer is used to filter dust, further improving the dust prevention effect. BRIEF DESCRIPTION OF THE DRAWINGS
