Description

Technical Field

[0001] The utility model belongs to the technical field of coal pile sensors, in particular to an adjustable coal pile sensor. Background Art

[0002] The coal pile sensor is a signal acquisition unit for belt conveyor coal pile protection. It is suitable for coal mines with gas and coal dust explosion hazards, as well as workplaces such as open-pit coal mines and coal preparation plants. It is mainly used as a coal level protection signal and detection for the comprehensive protection and control device of mining belt conveyors. It is a powerful measure to achieve automatic control and high efficiency energy saving.

[0003] Currently, in actual applications, existing radar-type coal pile sensors are often installed in locations that come into contact with coal, causing coal blocks to collide with the equipment, affecting its stability. They are also prone to absorbing dust, which affects subsequent sensing effects.

[0004] In order to solve the above problems, this application proposes an adjustable coal pile sensor. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable coal pile sensor, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is an adjustable coal pile sensor, comprising: a coal pile sensor and a fixing frame; a transfer column is provided above the coal pile sensor, which is spirally connected to a fixing rod at one end of the fixing frame through a screw rod above the transfer column to adjust the use height of the coal pile sensor; a partition net is provided on the outside of the coal pile sensor to block the entry of coal blocks, a limit frame is provided on the outside of the transfer column and a double-layer ring frame on the outside thereof, an outer ring frame is provided above the partition net to form a rotational connection with an open groove on the outside of the double-layer ring frame, and when the coal block hits the partition net, it is pushed to form a rotational unloading force; a telescopic rod is provided inside the double-layer ring frame, and a spring on the outside thereof is used to form an elastic vibration force when the coal block hits the partition net, so that the dust in the mesh of the partition net falls off to form a clean state.

[0008] Furthermore, an inner ring frame is provided on the inner side of the outer ring frame and is rotatably mounted inside the double-layer ring frame, and the axis of the inner ring frame and the limiting frame are in an eccentric distribution state.

[0009] Furthermore, a positioning groove is provided at the lower end of the inner ring frame for installing balls to reduce the friction resistance between the inner ring frame and the double-layer ring frame, so that the screen can be easily driven to rotate by the impact of coal blocks.

[0010] Furthermore, a positioning ball is provided at one end of the telescopic rod for abutting against the inner side surface of the inner ring frame.

[0011] Furthermore, a bolt and nut structure is provided at the upper end of the limit frame, and the distance reduced when the nut is tightened forms a clamping effect on the adapter column to fix the limit frame.

[0012] Furthermore, the telescopic rods are distributed at equal intervals in the circumferential direction on the inner side of the double-layer ring frame.

[0013] Furthermore, the inner and outer double-layer structures of the double-layer ring frame are also used to utilize the transverse structure at the bottom of the inner layer to form a supporting effect on the outer ring frame, thereby maintaining the stability of the structure.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can effectively block the entry of external coal blocks by adding a partition net, so as to prevent the coal pile sensor from being damaged by the impact of coal blocks, and utilizes the rotatable connection between the outer ring frame and the open groove to make the partition net automatically rotate when the coal blocks hit it, so as to achieve the effect of unloading force. Compared with the existing protection method, it can effectively prevent the strong negative impact caused by the impact of coal blocks, so as to ensure the normal performance of the equipment.

[0016] In addition, by utilizing the built-in telescopic rod and the spring on its outside, the inner ring frame can be retracted to form elastic vibration when the coal block hits it, so that the dust in the mesh of the partition will automatically fall down to prevent blockage caused by long-term adsorption, thereby ensuring the long-term use of the equipment and improving the practical performance of the equipment.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] See also Figure 1-4 As shown, the utility model is an adjustable coal pile sensor, comprising: a coal pile sensor 1 and a fixing frame 2; an adapter column 4 is provided above the coal pile sensor 1, and a screw rod 9 above the adapter column 4 is screwedly connected to a fixing rod 3 at one end of the fixing frame 2 to adjust the operating height of the coal pile sensor 1;

[0028] A screen 8 is provided on the outside of the coal pile sensor 1 to prevent coal from entering. A limit frame 5 and a double-layer ring frame 6 are provided on the outside of the adapter column 4. An outer ring frame 7 is provided above the screen 8 to form a rotational connection with the open groove 16 on the outside of the double-layer ring frame 6. When the coal hits the screen 8, it pushes it to form a rotational unloading force.

[0029] The double-layer ring frame 6 is provided with a telescopic rod 11 inside. When the coal block hits the screen 8, the spring 14 on the outside forms an elastic vibration force, which causes the dust in the mesh of the screen 8 to fall off and become clean.

[0030] This embodiment provides a coal pile sensing device for preventing coal block collisions. By utilizing the blocking and rotational unloading method of the partition net 8, the negative impact of coal mine collisions can be effectively reduced. In combination with the telescopic rod 11 and the spring 14, the partition net 8 vibrates so that the dust in the mesh is automatically detached to achieve a cleaning effect, thereby reducing the difficulty of equipment maintenance during use.

[0031] Among them, an inner ring frame 10 is provided on the inner side of the outer ring frame 7 and is rotatably installed inside the double-layer ring frame 6, and the axis of the inner ring frame 10 and the limit frame 5 are eccentrically distributed, so that the partition net 8 swings when it is hit, forming a certain unloading effect and guiding its force to the outside.

[0032] Among them, a positioning groove 13 is opened at the lower end of the inner ring frame 10 for installing the ball 12 to reduce the friction resistance between the inner ring frame 10 and the double-layer ring frame 6, so that the partition 8 can be easily driven by the impact of the coal blocks to produce rotational motion, causing the coal blocks to deviate from the original motion trajectory.

[0033] One end of the telescopic rod 11 is provided with a positioning ball 15 for pressing against the inner side surface of the inner ring frame 10 to transmit elastic vibration force.

[0034] The upper end of the limiting frame 5 is provided with a bolt and nut structure, and the spacing reduced when the nut is tightened forms a clamping effect on the adapter column 4 to fix the limiting frame 5.

[0035] The telescopic rods 11 are distributed at equal intervals in the circumferential direction on the inner side of the double-layer ring frame 6 .

[0036] The inner and outer double-layer structures of the double-layer ring frame 6 are also used to utilize the transverse structure at the bottom of the inner layer to form a supporting effect for the outer ring frame 7, thereby maintaining the stability of the structure.

[0037] It can be understood that the utility model can prevent coal blocks from hitting the equipment. The blocking and rotational unloading method of the partition net 8 can effectively reduce the negative impact of coal mine collision. Combined with the telescopic rod 11 and the spring 14, the partition net 8 vibrates so that the dust in the mesh is automatically detached to achieve a cleaning effect, thereby reducing the difficulty of equipment maintenance during use.

[0038] A specific application of the operating process of this embodiment is: when in use, first use the screw 9 and the fixed rod 3 to adjust the use height of the coal pile sensor 1, and then install the limit frame 5 on the outside of the adapter column 4 through the bolts. At this time, the partition net 8 forms a protection for the coal pile sensor 1 to prevent the external coal blocks from directly hitting the coal pile sensor 1 and causing damage. When the coal blocks hit the partition net 8, the ball 12 is used to reduce the friction resistance of the inner ring frame 10, and it can rotate according to the impact direction of the coal mine to achieve the effect of unloading force. At the same time, the spring 14 is used to form an elastic vibration force on the inner ring frame 10, so that the dust in the mesh of the partition net 8 falls off downward to achieve the effect of automatic cleaning, so as to ensure the protection effect of the coal pile sensor 1 and maintain a stable use state for a long time.
