Description

Technical Field

[0001] The utility model relates to the field of level meters, in particular to an integrated installation device for high-altitude level measurement. Background Art

[0002] At high-altitude mine sites (the site application altitude is 5,300 meters), affected by the site environment (low temperature, reduced air insulation strength, reduced heat dissipation capacity, high dust concentration, high mechanical vibration intensity, etc.), the difficulty of mine warehouse level detection increases exponentially. Not only the form of the level meter should be considered, but also various factors such as how to install the level meter, power distribution, shockproof and dustproof. Inappropriate installation methods lead to increased frequency and difficulty of on-site instrument maintenance, and even require on-site equipment shutdown and cooperation. In high-altitude environments, the labor capacity of personnel drops sharply. Therefore, choosing a suitable installation device is particularly important for improving the accuracy of instrument detection, extending the service life of the instrument, and reducing the intensity and frequency of workers' maintenance work on the instrument.

[0003] Large ore silos are distributed through belt conveyors and mobile distribution carts. The best detection point for level monitoring is directly below the belt conveyor or mobile distribution cart. However, there is no installation platform at this location. There is a lot of dust directly below the belt conveyor, which is easily hit by falling materials and is subject to large mechanical vibrations from the operation of the belt conveyor and distribution cart. The existing technology uses a simple bracket installation or flange fixed installation type to fix the level meter on the platform above the silo (the radar level meter emission angle needs to be adjusted, which is not the optimal detection position). This installation method is easily affected by mechanical vibrations on site. After running for a period of time, the probe is covered with dust and accurate measurement results cannot be obtained. There is no effective protection for the air pipes or wires on site, and the materials in the silo are easily hit by the air pipes or wires during the falling process, causing equipment failure.

[0016] (III) Beneficial effects

[0017] The beneficial effects of the utility model are: the main channel steel is stably fixed on the installation frame; since the main channel steel is the load-bearing main channel steel on the top of the silo, the impact of mechanical vibration after installation is much less than that of installation in other positions.

[0029] For example, please refer to Figure 1 As shown:

[0030] An integrated installation device for high-altitude level measurement includes an installation frame 100 for installation on a main channel steel 200; the main channel steel 200 is a load-bearing main channel steel 200 on the top of a silo. After installation, the main channel steel 200 is much less affected by mechanical vibration than when installed at other locations. The main channel steel 200 is located directly below the cloth belt, and the level meter 170 does not need to adjust the emission angle, thereby ensuring the availability and reliability of the measurement data. Compared with the bracket or flange 171 installed on the color steel plate on the top of the silo, it has better stability, so that the level meter 170 is not easily disturbed by on-site mechanical vibration, thereby improving the measurement accuracy; the bottom of the installation frame 100 is connected to the level meter 170; one side of the installation frame 100 is provided with an installation port 101 that allows the main channel steel 200 to enter the installation frame 100; the installation port 101 is provided with a limit rod 140 that prevents the installation frame 100 from detaching from the main channel steel 200; the installation frame 100 is also provided with a cleaning component for cleaning the level meter 170;

[0031] In one embodiment of the utility model, the main channel steel 200 is first limited by the installation frame 100, and further double protection is achieved by using the limiting rod 140; the installation frame 100 generally includes a top plate 110, one side of the top plate 110 is connected to the bottom plate 130 through the side plate 120, and the top plate 110 and the bottom plate 130 are arranged on the same side of the side plate 120; similarly, the top plate 110 and the bottom plate 130 are arranged in parallel; the space between the top and the bottom plate 130 is used to accommodate the main channel steel 200, and the other side of the space opposite to the side plate 120 is the installation opening 101, and the main channel steel 200 enters the interior of the installation frame 100 through the installation opening 101;

[0032] In one embodiment of the utility model, the main channel steel 200 can be fixed in advance using the mounting frame 100; the top plate 110 is provided with a fixing bolt 111; the fixing bolt 111 is threadedly connected to the top plate 110, and one end of the fixing bolt 111 can extend into the mounting frame 100, so that the length of the fixing bolt 111 extending into the mounting frame 100 can be adjusted by rotating the fixing bolt 111, so that the fixing bolt 111 is abutted against the main channel steel 200, and the main channel steel 200 is fixed in cooperation with the bottom plate 130;

[0033] In one embodiment, a baffle plate may be provided at the lower end of the fixing bolt 111, and the baffle plate is used to abut against the main channel steel 200, thereby having a larger contact area and thus having better connection stability;

[0034] In one embodiment, a plurality of fixing bolts 111 may be provided, so as to fix the main channel steel 200 in a manner of multiple surface contacts, which can achieve a better fixing effect; since the end surface of the main channel steel 200 abutting against the fixing bolts 111 is not completely flat, a plurality of fixing bolts 111 abutting against the main channel steel 200 has a better fixing effect;

[0035] In one embodiment, the external thread of the fixing bolt 111 is connected to the internal thread of the connecting seat 112; the connecting seat 112 is fixed on the top plate 110; one end of the fixing screw can extend into the installation frame 100;

[0036] In one embodiment, the bottom plate 130 is provided with connection protrusions 131 for abutting against the main channel steel 200 at intervals on one side surface relative to the fixing bolt 111; since the end surface of the main channel steel 200 abutting against the fixing bolt 111 is not completely flat, abutting against the main channel steel 200 by a plurality of connection protrusions 131 has a better fixing effect; three connection protrusions 131 are provided, arranged in a triangular shape; the connection protrusion 131 is cylindrical, and a hollow portion may be provided inside thereof. The connection protrusion 131 is made of a flexible material such as rubber or silicone, which can achieve a buffering effect and reduce the influence of vibration on the level meter 170. At the same time, when the hollow portion abuts against the main channel steel 200, the air in the hollow portion is discharged due to the deformation of the connection protrusion 131, and the negative pressure can be used to increase the connection effect with the main channel steel 200;

[0037] In one embodiment of the present invention, the limit rod 140 is rotatably connected to one end of the bottom plate 130 away from the side plate 120; the limit rod 140 is rotatably connected to the bottom plate 130 via a rotating shaft 141 structure; a locking assembly 150 that can locate the position of the limit rod 140 is provided on one side of the top away from the side plate 120; Figure 1 , Figure 3As shown, when the limiting rod 140 rotates counterclockwise, the installation opening 101 is opened, and the main channel steel 200 can be conveniently installed into the installation frame 100. The main channel steel 200 is fixed by rotating the fixing bolt 111 to abut against the main channel steel 200 and cooperate with the connecting protrusion 131. The limiting rod 140 is further rotated clockwise, and the end of the limiting rod 140 away from the bottom plate 130 cooperates with the locking assembly 150 to achieve the positioning of the limiting rod 140. The limiting rod 140 cannot rotate, thereby closing the installation opening 101, and the main channel steel 200 cannot be separated from the installation frame 100. The dual limiting of the fixing bolt 111 and the limiting rod 140 effectively prevents the main channel steel 200 from being separated from the installation frame 100.

[0038] like Figure 2 As shown, in one embodiment of the present invention, the end of the limit rod 140 near the top is provided with a locking plate 142; the locking plate 142 is provided with a locking hole 143; the locking assembly 150 includes a plurality of limit plates 152 and a stop plate 153 spaced apart on the side away from one end of the side plate 120, and a push-pull rod 151 movably connected in the limit plate 152 and the stop plate 153; the push-pull rod 151 can move linearly or rotate in the limit plate 152 and the stop plate 153 Movement, through linear movement to approach or move away from the locking plate 142, in order to realize the linear and rotational movement of the push-pull rod 151, the limit plate 152 and the stop plate 153 only need to be provided with through holes or grooves to allow the push-pull rod 151 to pass through; when the end of the push-pull rod 151 is inserted into the locking hole 143, the limit rod 140 can be locked; when the end of the push-pull rod 151 is separated from the locking hole 143, the limit rod 140 can be unlocked, and the limit rod 140 can rotate freely;

[0039] In one embodiment, a handle 155 is provided on the push-pull rod 151, and the handle 155 can conveniently realize the linear and / or rotational movement of the push-pull rod 151 along the axial direction, so as to facilitate the rapid matching and disengagement of the push-pull rod 151 and the locking hole 143; the stop plate 153 is arranged close to the handle 155; the stop plate 153 is provided with a clearance groove 154 for allowing the handle 155 to pass through; a limit member 158 is provided at one end of the push-pull rod 151 away from the limit rod 140; the limit plate 152 is arranged close to the limit member 158; a return spring 159 is provided between the limit member 158 and the limit plate 152;

[0040] In one embodiment, see Figure 2 In the state shown in , the return spring 159 is in a compressed state. When the handle 155 is turned clockwise to the position of the give way groove 154, the elastic force of the return spring 159 is released, driving the push-pull rod 151 to move in the direction of the lower right side, so that the push-pull rod 151 can quickly disengage from the locking hole 143, thereby realizing quick unlocking;

[0041] In one embodiment, see Figure 2 In the state shown in , the reset spring 159 is in a normal state. When the handle 155 is turned clockwise to the position of the yield groove 154, the reset spring 159 will not move, and quick unlocking cannot be achieved. The push-pull rod 151 needs to be manually pulled to the lower right side to unlock the limit rod 140, which can avoid accidentally unlocking the limit rod 140 during vibration or collision, and ensure the normal operation of the limit rod 140;

[0042] In one embodiment, the locking assembly 150 includes two positioning plates 156 that are arranged opposite to each other; when the locking hole 143 cooperates with the push-pull rod 151, the locking plate 142 is located between the two positioning plates 156, and the positioning plate 156 is provided with a positioning groove 157 that allows the push-pull rod 151 to pass through; the position of the limit rod 140 is limited by the positioning plate 156, so that the movable stroke of the push-pull rod 151 can meet the locking and unlocking states of the limit rod 140, and also avoids the limit rod 140 from being separated from the push-pull rod 151 in special circumstances;

[0043] In one embodiment, a plurality of protective tubes 121 are fixedly provided on the side plate 120; the cleaning assembly includes an air blowing pipeline or a water outlet pipeline; the air outlet pipeline or the water outlet pipeline is arranged in the protective tube 121 and extends toward the level meter 170, and the level meter 170 is cleaned by intermittent or continuous air blowing through the air outlet pipeline; or the level meter 170 is cleaned by intermittent or continuous water discharge through the water outlet pipeline; the protective tube 121 can ensure the safety of the air outlet pipeline or the water outlet pipeline, prevent smashing and collision, reduce maintenance frequency, and extend the service life of the equipment. At the same time, the wiring harness can also be routed in the protective tube 121, and signal transmission wires, distribution wires, etc. can be routed through the protective tube 121, effectively protecting the safety of the lines / pipelines;

[0044] In one embodiment, the base plate 130 is fixedly connected to the level meter 170 via a level meter mounting bracket 160; the level meter mounting bracket 160 includes at least one extension plate 161 extending from the bottom of the base plate 130; an end of the extension plate 161 away from the base plate 130 extends to form a mounting base plate 162 for fixing the level meter 170; the level meter 170 is fixedly connected to the mounting base plate 162 via a flange 171; the mounting base plate 162 is arranged parallel to the bottom; two extension plates 161 are usually arranged opposite to each other, so as to ensure the stability of the mounting base plate 162.
