Specific implementation mode

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0027] As Figure 1 shown:

[0028] A braking protection device for a pumping unit, including the main body 1 of the pumping unit pulley.

[0029] In this implementation: To solve the technical problems existing in this prior art, as disclosed in the background art above, "The current pumping unit is the most important surface oil production device in the oil production plant, and its safety control device is the most important safety facility. Due to factors such as the environment, human damage, and mechanical failures, there are prone to situations such as the lack of a braking device, brake failure, and self-sliding of the pumping unit pulley, resulting in major safety hazards during equipment operation, poor protection effect, and reduced use effect of the device." In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a locking assembly 2 is added in this application document, and all the power equipment involved in this product is powered by an external power supply.

[0030] Furthermore:

[0031] As Figures 1-4 shown:

[0032] A locking assembly 2 is provided on one side of the main body 1 of the pumping unit pulley. The locking assembly 2 includes a mounting seat 201 provided on one side of the main body 1 of the pumping unit pulley, two groups of limiting rods 209 fixedly arranged symmetrically inside the mounting seat 201, and a side plate 210 sliding on the surfaces of the two groups of limiting rods 209;

[0033] One end of the side plate 210 is fixedly installed with a brake disc 211 through bolts. The brake disc 211 is arranged at the inner cavity of the main body 1 of the pumping unit pulley;

[0034] Two symmetrically arranged tension springs 212 are fixedly installed between the two side plates 210. The tension springs 212 are used to expand and reset the two side plates 210;

[0035] On the sides of the side plate 210 close to each other, inclined blocks 208 are fixedly installed through bolts. An extrusion block 207 is arranged between the two inclined blocks 208. An electric push rod 205 for driving the extrusion block 207 to extrude the two inclined blocks 208 is arranged on one side of the mounting seat 201;

[0036] Connecting plates 202 are arranged on both sides of the mounting seat 201. Symmetrically arranged locking bolts 203 are arranged through the reserved holes of the connecting plates 202;

[0037] A rotational speed sensor 206 for detecting the rotational speed of the main body 1 of the pumping unit pulley is fixedly installed on one side of the mounting seat 201 through a mounting plate;

[0038] A rectangular through groove is opened on one side of the surface of the mounting seat 201 close to the two groups of limiting rods 209. One end of the side plate 210 is located in the rectangular through groove opened on the mounting seat 201. Through holes adapted to the limiting rods 209 are opened on the surface of the side plate 210. The side plate 210 and the limiting rods 209 are slidably connected through these through holes;

[0039] A U-shaped plate 204 is fixedly installed on one side of the mounting seat 201 through bolts. The electric push rod 205 is fixedly installed on the surface of the U-shaped plate 204 through bolts. The output end of the electric push rod 205 is fixed on one side surface of the extrusion block 207;

[0040] Inclined surfaces adapted to the inclined blocks 208 are arranged on both sides of the extrusion block 207.

[0041] In this implementation: When the brake protection device of the pumping unit is in use, first, this structure is installed on the housing of the pumping unit at the position of the main body 1 of the pumping unit pulley through the locking bolt 203. At this time, the brake disc 211 is located inside the main body 1 of the pumping unit pulley. Subsequently, the rotational speed of the main body 1 of the pumping unit pulley is detected by the rotational speed sensor 206. When the rotational speed detected by the rotational speed sensor 206 exceeds a certain value or when the main body 1 of the pumping unit pulley stops rotating, the rotational speed sensor 206 controls the electric push rod 205 to start running by controlling a controller (not shown in the figure).

[0042] When the electric push rod 205 starts, it drives the extrusion block 207 to move. At this time, the extrusion block 207 extrudes the two inclined blocks 208, causing the two inclined blocks 208 to drive the side plate 210 to move away from each other on the surface of the limiting rod 209, and at the same time, stretching the two tension springs 212. Through the setting of the tension springs 212, when the extrusion of the side plate 210 is released, at this time, through the rebound and contraction of the tension springs 212, the side plate 210 can be driven to reset. The side plate 210 drives the brake disc 211 to move, and the brake disc 211 extrudes the inner side wall of the main body 1 of the pumping unit pulley, so that the rotating main body 1 of the pumping unit pulley can be suddenly braked and locked, and the main body 1 of the pumping unit pulley after stopping rotating can be locked to prevent self-sliding. This structure can thus add a guarantee. In the case of the absence or ineffective braking of the braking device, it can firmly lock the pulley of the speed reducer, prevent self-sliding and slipping, avoid major safety hazards during the operation of the equipment, ensure the safety of personnel, and can play a role in strengthening the protection and improving the use effect of the device.

[0043] It should be noted that: The rotational speed sensor 206 measures the rotational speed of the main body 1 of the pumping unit pulley and converts this information into electrical signals, and then sends these signals to the controller. A specific rotational speed threshold is set inside the controller. When the rotational speed detected by the rotational speed sensor 206 reaches or exceeds this threshold, the controller sends a start signal to the electric push rod 205. After receiving the signal, the electric push rod 205 starts to work;

[0044] The rotational speed sensor 206 is a laser velocimeter. It measures the rotational speed by emitting laser light to the surface of the main body 1 of the pumping unit pulley and analyzing the reflected light. The laser light reflected from the surface changes due to the rotation of the main body 1 of the pumping unit pulley. By analyzing these changes, the rotational speed can be calculated;

[0045] The rotational speed sensor 206 is connected to the controller via a signal line. This signal line usually transmits an electrical signal (such as a voltage or current signal) proportional to the rotational speed. When connecting, it is necessary to ensure that the output signal type of the sensor matches the signal type that the controller can accept. The controller is connected to the electric push rod 205 via a control signal line. When the controller receives the signal sent by the rotational speed sensor 206 and determines that the electric push rod 205 needs to be started, it will send a start signal to the electric push rod 205 through this control line. The electric push rod 205 and the controller are connected to an external power supply through a power adapter for power supply.

[0046] Furthermore;

[0047] In an optional embodiment, on one side of the surface of the connecting plate 202 close to the mounting seat 201, symmetrically arranged adjusting frames 213 are fixed. A plurality of groups of equally spaced mounting holes 214 are formed on the surface of the adjusting frame 213. On one side of the surface of the mounting seat 201 close to the adjusting frame 213, symmetrically arranged limit bolts 215 are provided. Threaded holes adapted to the limit bolts 215 are formed on the surface of the mounting seat 201. One end of the limit bolt 215 is screwed into the threaded hole of the mounting seat 201 and inserted into the corresponding mounting hole 214 of the adjusting frame 213. A sliding groove adapted to the adjusting frame 213 is formed on the surface of the mounting seat 201. The adjusting frame 213 and the mounting seat 201 are slidably connected through this sliding groove.

[0048] In this embodiment: By rotating the limit bolt 215, the limit bolt 215 is pulled out from the mounting hole 214, and then the position locking between the adjusting frame 213 and the mounting seat 201 is released. Then, rotate the locking bolt 203 to separate the connecting plate 202 from the housing of the pumping unit pulley main body 1. Subsequently, one side of the connecting plate 202 and the mounting seat 201 are closely attached. Then, rotate the two groups of limit bolts 215, and then insert the limit bolts 215 into the corresponding mounting holes 214 of the adjusting frame 213 to lock the positions of the mounting seat 201 and the adjusting frame 213, thereby reducing the overall structural volume, facilitating carrying, and further improving the use effect of the device.

[0049] Working principle and usage process of the utility model: For this brake protection device of the pumping unit, during use, first install this structure on the housing of the pumping unit at the position of the main body 1 of the pumping unit pulley through the locking bolt 203. At this time, the brake disc 211 is inside the main body 1 of the pumping unit pulley. Subsequently, detect the rotation speed of the main body 1 of the pumping unit pulley through the rotation speed sensor 206. When the rotation speed sensor 206 detects that the rotation speed of the main body 1 of the pumping unit pulley exceeds a certain value or the main body 1 of the pumping unit pulley stops rotating, control the electric push rod 205 to start running through the rotation speed sensor 206 to control the controller (not shown in the figure). Through the start of the electric push rod 205, drive the extrusion block 207 to move. At this time, the extrusion block 207 extrudes the two inclined blocks 208, causing the two inclined blocks 208 to drive the side plate 210 to move away from each other on the surface of the limiting rod 209, and at the same time stretch the two tension springs 212. Through the setting of the tension springs 212, when the extrusion of the side plate 210 is released, at this time, through the rebound and contraction of the tension springs 212, the side plate 210 can be driven to reset. Drive the brake disc 211 to move through the side plate 210, and squeeze the inner side wall of the main body 1 of the pumping unit pulley through the brake disc 211, so as to quickly brake and lock the rotating main body 1 of the pumping unit pulley, and lock the main body 1 of the pumping unit pulley after stopping rotation to prevent self-sliding. This structure can thus add a guarantee. In the case of the absence or poor braking of the braking device, it can firmly lock the belt pulley of the speed reducer, prevent self-sliding and slipping, avoid major safety hazards during equipment operation, ensure personnel safety, and play a role in strengthening protection, improve the use effect of the device. By rotating the limit bolt 215, pull out the limit bolt 215 from the mounting hole 214, and then release the position lock between the adjusting frame 213 and the mounting seat 201. Then rotate the locking bolt 203 to separate the connecting plate 202 from the housing of the main body 1 of the pumping unit pulley. Subsequently, the connecting plate 202 and one side of the mounting seat 201 are closely attached. Then rotate the two limit bolts 215, and then insert the limit bolts 215 into the corresponding mounting holes 214 of the adjusting frame 213 to lock the positions of the mounting seat 201 and the adjusting frame 213, thereby reducing the overall structure volume, being convenient to carry, and further improving the use effect of the device.

[0050] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
