Description

Technical Field

[0001] The utility model belongs to the field of pressure transmitter supporting devices, in particular to a fire-resistant oil pressure transmitter supporting device. Background Art

[0002] A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. Fire-resistant oil (EH oil) is a type of oil in a steam turbine system that is specifically used to drive the turbine regulating switch. Pressure transmitters are usually used to monitor the oil pressure in the fire-resistant oil pipeline. The pressure transmitter is connected to the fire-resistant oil pipeline through a pressure lead pipeline. The pressure transmitter is usually not fixed, and is only supported by the pressure lead pipeline next to the fire-resistant oil pipeline. Since the steam turbine will also generate certain vibrations when it is working, the vibrations will be transmitted to the pressure transmitter through the pressure lead pipeline, causing damage to the pressure transmitter. It may also cause the connection between the pressure transmitter and the pressure lead pipeline to loosen or even rupture, affecting safety. There are many different types of pressure transmitters on the market. How to stably install different types of pressure transmitters and quickly replace or disassemble and repair the pressure transmitter is a problem that needs to be solved. Utility Model Content

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] A fire-resistant fuel pressure transmitter support device, such as Figure 1 , 2 As shown, it includes a clamping assembly and a locking assembly 10; the clamping assembly includes a static clamping plate 5, a guide rod 4 and a dynamic clamping plate 11, the static clamping plate is fixedly arranged on the wall 1 through a bracket 7, the static clamping plate and the dynamic clamping plate are arranged in parallel, and a clamping gap for accommodating a pressure transmitter is formed between the static clamping plate and the dynamic clamping plate, and the static clamping plate and the dynamic clamping plate can stably clamp the pressure transmitter in the clamping gap;

[0031] The guide rod is arranged vertically with the static clamping plate, one end of the guide rod is fixedly connected with the lower end of the static clamping plate, the dynamic clamping plate is slidably arranged on the guide rod and can slide along the guide rod toward or away from the static clamping plate; a limit rod 6 is also arranged on the static clamping plate, and a plurality of limit grooves 22 arranged along the length direction are provided on the limit rod, one end of the limit rod is fixedly connected with the lower end of the static clamping plate, the limit rod and the guide rod are arranged parallel, and a pipeline channel is formed between the limit rod and the guide rod to allow the pressure supply pipeline of the pressure transmitter to pass through; a through hole is provided on the dynamic clamping plate for accommodating the limit rod, and when the dynamic clamping plate slides along the guide rod, it also slides along the limit rod at the same time, and a locking assembly for locking the dynamic clamping plate and the limit rod to each other is provided on the dynamic clamping plate next to the through hole.

[0032] A static V-shaped groove 3 is provided on the surface of the static clamping plate near the clamping gap, and a dynamic V-shaped groove 9 is provided on the surface of the dynamic clamping plate near the clamping gap. The static V-shaped groove and the dynamic V-shaped groove are of the same size and aligned with each other, and both are V-shaped openings facing upward. The static clamping plate is made of transparent material, so that some pressure transmitters with digital display functions can still read the readings under the support of the static clamping plate.

[0033] A static guide plate 2 is provided at the upper end of the static clamping plate, and a dynamic guide plate 8 is provided at the upper end of the dynamic clamping plate. The surface of the static guide plate close to the clamping gap and the surface of the dynamic guide plate close to the clamping gap are both inclined surfaces, and the two inclined surfaces are respectively extended upward in a direction away from the clamping gap from the upper ends of the two end surfaces of the static V-groove and the dynamic V-groove that are aligned with each other; the two inclined surfaces can respectively guide the front end face and the rear end face of the pressure transmitter into the static V-groove and the dynamic V-groove, and pressure transmitters of different models and sizes can be inserted into the static V-groove and the dynamic V-groove toward the bottom of the V-groove and be clamped front and back by the static clamping plate and the dynamic clamping plate, and the pressure transmitter can be limited while avoiding lateral movement.

[0034] like Figure 3 , 4 As shown in , 5, the locking assembly includes a fixed plate 14, a lock buckle and a locking member. The fixed plate is arranged on the surface of the movable clamping plate on one side of the limiting rod. The lock buckle includes a connecting section 13 and a mounting section 16. One end of the connecting section is rotatably connected to the top end of the fixed plate through a hinge shaft 12. The mounting section is vertically arranged at the other end of the connecting section and extends to the other side of the limiting rod. A locking gap capable of accommodating the limiting rod is provided between the mounting section and the fixed plate; an arc-shaped groove 23 capable of matching with the surface of the limiting rod is provided on the surface of the mounting section close to the limiting rod; an accommodating groove 17 is provided on the mounting section in alignment with the other side of the limiting rod, and a rotating shaft 21 parallel to the limiting rod is provided in the accommodating groove, and the locking member is rotatably provided on the rotating shaft;

[0035] The locking member includes a locking end 18 and an operating end 19. The locking end is located on the side of the rotating shaft close to the limit rod and can be inserted into the limit groove. The operating end is located on the side of the rotating shaft away from the limit rod. Both the locking end and the operating end are provided with outer arc surfaces. When the two outer arc surfaces are connected, they form a semicircular arc surface. The arc centers of the two outer arc surfaces coincide with the axis center of the rotating shaft.

[0036] The locking end can extend from the opening of the accommodating groove close to the limit rod and can be inserted into the limit groove. The limit groove is provided with an inner arc surface that can match the outer arc surface. The curvature of the inner arc surface is the same as that of the outer arc surface. When the locking end is inserted into the limit groove, the outer arc surface can fit with the inner arc surface; the outer arc surface of the locking end and the inner arc surface of the limit groove can ensure that the locking end will not push the limit groove to cause displacement of the limit rod when inserted into or pulled out of the limit groove, and also avoid the locking end from being stuck during the insertion or removal process.

[0037] The operating end can extend from the opening of the receiving groove away from the limiting rod, and an operating part is arranged on the outer arc surface of the operating end, and the operating part can be a component that can increase friction, such as a receiving groove, a friction pad, etc. on the arc surface, so that the staff can turn the operating end to pull the locking end out of the limiting groove to unlock the lock buckle. After the lock buckle is unlocked, the locking assembly is out of the locking state of the movable clamping plate, and the movable clamping plate can slide along the guide rod and the limiting rod. The operating part cannot prevent the locking end from being inserted into the limiting groove.

[0038] A torsion spring is provided on the rotating shaft, and the two ends of the torsion spring are respectively connected to the locking member and the rotating shaft. The torsion spring can provide a rotational force to the locking member so that the locking end can automatically rotate in the direction of the limiting rod. The locking end can automatically insert into the limiting groove when aligned with the limiting groove under the rotational force provided by the torsion spring. When the locking end is inserted into the limiting groove, the lock buckle is fixed to the other side of the limiting rod. At this time, the lock buckle fits the limiting rod, the locking assembly is in a locked state, and the movable clamp is locked in the long direction of the limiting rod; when the locking end is pulled out of the limiting groove by toggling the operating part, the lock buckle can rotate from the other side of the limiting rod to the direction away from the limiting rod. When the lock buckle rotates in the direction away from the limiting rod, the locking end can be reset and rotated toward the limiting rod under the action of the torsion spring and extend from the receiving groove of the lock buckle. The locking end can be pulled out of the limit groove and the lock buckle can be unlocked by simply toggling the operating part so that the lock buckle can rotate, thereby unlocking the movable clamping plate so that the movable clamping plate can slide along the guide rod and the limit rod, and the pressure transmitter can be removed conveniently and quickly for replacement or maintenance.

[0039] When the lock buckle rotates from the open state to the limit rod, the locking end moves along the arc surface of the limit rod to the limit groove with the rotation of the lock buckle. When the locking end rotates with the lock buckle to align with the limit groove, it can automatically insert into the limit groove under the action of the torsion spring; when the locking end is inserted into the limit groove, the movable clamping plate is locked in the axial direction of the limit rod. This process can quickly clamp the pressure transmitter installed in the clamping gap by automatically locking the movable clamping plate, which is suitable for the rapid installation of different types of pressure transmitters.

[0040] A limiting block 15 is fixedly arranged on the surface of the fixed plate close to the limiting rod, and a non-slip arc surface is arranged on the surface of the limiting block close to the limiting rod for accommodating the limiting rod, the non-slip arc surface can fit with one side of the limiting rod, and a non-slip pad is arranged on the non-slip arc surface, which can cooperate with the arc-shaped groove of the mounting section. When the locking member does not lock the movable clamping plate in the long direction of the limiting rod, it can still maintain a certain friction with the limiting rod to prevent the movable clamping plate from moving over a large range.

[0041] In this embodiment, Figure 3 The figure shows the locked state of the locking assembly. At this time, the locking end is inserted into the limit groove, the lock buckle is attached to the limit rod, and the locking assembly locks the movable clamping plate so that the movable clamping plate cannot move in the long direction of the limit rod. At this time, the clamping gap between the movable clamping plate and the static clamping plate remains unchanged, and the movable clamping plate and the static clamping plate can stably clamp the pressure transmitter; Figure 4 The figure shows the state where the locking end is pulled out of the limiting groove. At this time, the lock buckle can rotate in the direction away from the limiting rod. When the lock buckle rotates in the direction away from the limiting rod, the locking end can be reset under the action of the torsion spring, and the locking end extends out of the receiving hole again. Figure 5 As shown; after the locking end is pulled out of the limit groove, the limit of the locking assembly in the long direction of the limit rod is released, and the movable clamping plate can slide along the guide rod and the limit rod to quickly install, replace or disassemble the pressure transmitter for maintenance.

[0042] The effects of the above scheme are described below:

[0043] (1) The pressure transmitter can be clamped by the static clamping plate and the dynamic clamping plate, and the dynamic clamping plate is locked and fixed by the locking mechanism, so as to maintain the clamping state of the pressure transmitter; the static V-groove, the dynamic V-groove, the static guide plate and the dynamic guide plate can adapt to various types of pressure transmitters, and can clamp the pressure transmitter quickly and stably. The pipeline channel between the guide rod and the limit rod can be used for the pressure pipeline to pass through;

[0044] (2) The anti-slip arc surface of the limit block and the arc-shaped groove of the lock buckle can fit with the limit rod. The anti-slip pad on the limit block can prevent the movable clamping plate from sliding easily over a large range during the installation of the pressure transmitter even if it is not locked by the locking piece, which facilitates the rapid installation of the pressure transmitter;

[0045] (3) The locking end can be inserted into the limit groove to lock the movable clamp in the long direction of the limit rod to maintain a stable clamping state of the pressure transmitter, which is convenient for quick installation of the pressure transmitter. The locking end can be pulled out of the limit groove to release the lock of the locking assembly, so as to quickly replace or disassemble and repair the pressure transmitter;

[0046] (4) When the lock buckle rotates toward the limit rod, the locking end can move along the surface of the limit rod toward the limit groove with the lock buckle. When the locking end moves to a position aligned with the limit groove, it can automatically insert into the limit groove under the action of the torsion spring, thereby quickly and conveniently locking the movable clamp. While clamping the pressure transmitter, it can also prevent accidental loosening of the locking assembly due to accidental touch, thereby preventing the movable clamp from loosening and losing the clamping state of the pressure transmitter, causing damage to the pressure transmitter, or causing the connection between the pressure transmitter and the pressure lead pipeline to loosen or even rupture.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
