While some patents exist for auxiliary safety shutdown devices and manual / automatic braking systems, they target band brakes, with braking components such as brake bands and brake clamps. There is a lack of upgrade solutions specifically for disc brakes in wide-band chain reversing pumping unit braking systems.

[0035] Example 1:

[0036] Please see Figures 1 to 3 The wide-band chain reversing pumping unit dual-brake device provided in this embodiment includes a limit start part, a limit guide part 3, and an execution part 4.

The limit start part has a variable depth surface 2.2 in the limit guide part 3, and the execution part 4 is in contact with the variable depth surface. When the limit guide part 3 is stationary, the rotation of the limit start part can cause the execution part 4 to be pushed out or retracted by the variable depth surface 2.2. When the limit start part is stationary, the rotation of the limit guide part 3 can cause the execution part 4 to rotate, thereby causing the execution part 4 to be pushed out or retracted by the variable depth surface 2.2.

[0037] Furthermore, the limiting start part includes a column cam 2 and a first drive handle 1. The limiting guide part 3 includes a sleeve 3.1. One end of the column cam 2 is rotatably inserted into the sleeve 3.1. The end of the column cam 2 away from the sleeve 3.1 is connected to the first drive handle 1.

[0038] Among them, the limiting pin 3.2 and the limiting groove 4.3 enable the limiting guide part 3 and the actuating part 4 to rotate synchronously and slide axially.

[0039] Specifically, the first drive handle 1 includes a connecting part 1.1, a bending part 1.2, and a first fixing part 1.3; the connecting part is connected to the column cam 2, and the connecting part 1.1 contacts the end face of the sleeve 3.1 to achieve axial positioning of the column cam 2; the bending part 1.2 bends away from the second drive handle 3.3 to avoid collision between the first drive handle 1 and the second drive handle 3.3; the first fixing part 1.3 is provided with fixing holes to facilitate fixing the first drive handle 1 to the pumping unit frame with bolts.

[0040] Specifically, the cylindrical cam 2 includes a cylindrical body 2.1, and a variable depth surface 2.2 is provided at one end of the cylindrical body 2.1 near the transmission column 4.2. A spline block 2.3 is provided at the end face of the cylindrical body 2.1 near the first drive handle 1.

[0041] Preferably, the variable depth surface 2.2 is a radially penetrating corner groove with rounded corners at the bottom, allowing the transmission column 4.2 to move smoothly.

[0042] Specifically, the second drive handle 3.3 on the outer wall of the sleeve 3.1 is provided with a second fixing part, and a fixing hole is provided on the second fixing part to facilitate the connection of the second drive handle 3.3 to the automation linkage by bolts.

[0043] Specifically, the limiting groove 4.3 of the execution part 4 can be configured in various ways, such as setting the limiting groove 4.3 on the outer wall of the push plate 4.1, or setting a transition platform between the push plate 4.1 and the transmission column 4.2, with the limiting groove 4.3 set on the outer wall of the transition platform. In this embodiment, it is preferred that the limiting groove 4.3 is set on the outer wall of the transmission column 4.2, and the push plate 4.1 can contact the end face of the sleeve 3.1 to achieve positioning.

[0044] Preferably, the transmission column 4.2 is a round-headed column to ensure smooth transmission.

[0045] In this embodiment, the ejection and retraction of the execution part 4 are realized. The two drive handles can be used as automatic brake handles and manual brake handles respectively.

[0046] Example 2:

[0047] Based on Example 1, this example provides a braking system using a wide-band chain reversing pumping unit with dual braking devices, including the wide-band chain reversing pumping unit dual braking device and brake pad device described in Example 1.

[0048] Furthermore, the brake pad device includes a fixed seat 5, on which a brake pad 6 is fixed by bolts. A guide rod 9 perpendicular to the fixed brake pad 6 is welded to the fixed seat 5. A movable brake pad 7 is slidably disposed between the fixed brake pad 6 and the guide rod 9. The movable brake pad 7 is connected to the fixed seat 5 through a reset mechanism. The column cam 2 and push plate 4.1 are provided with a center hole. The column cam 2 and push plate 4.1 are sleeved on the guide rod 9. A positioning nut 10 is provided on the guide rod 9. The positioning nut 10 contacts the column cam 2 to achieve axial limiting. The push plate 4.1 contacts the movable brake pad 7.

[0050] Specifically, the movable brake pad 7 is provided with a transmission rod 7.1, which is a round-headed rod, and the head of the transmission rod 7.1 contacts the push plate 4.1.

[0051] Specifically, the movable brake pad 7 is slidably connected to the fixed seat 5 via a T-shaped guide rail and a T-shaped groove. The movable brake pad 7 is provided with a clearance groove 7.2 to prevent interference with the guide rod 9.

[0052] Specifically, the reset mechanism includes a reset spring 8, a first connecting seat 5.1, and a second connecting seat 7.2. The first connecting seat 5.1 is located on the side of the fixed seat 5 away from the fixed brake pad 6, and the second connecting seat 7.2 is located on the side wall of the movable brake pad 7. The two ends of the reset spring 8 are connected to the first connecting seat 5.1 and the second connecting seat 7.2 respectively through hooks. The reset spring 8 is in a stretched state, so that the movable brake pad 7 can automatically reset and release the brake when the actuator 4 is retracted.

[0053] Example 3:

[0054] Based on Example 2, this example provides a method for using a braking system with a wide-band chain reversing pumping unit dual braking device, including the following steps:

[0055] The brake pad assembly is installed on the brake disc of the wide-band chain reversing pumping unit, positioning the brake disc between the fixed brake pad 6 and the movable brake pad 7. The first fixing part 1.3 of the first drive handle 1 is connected to the frame with bolts, and the second fixing part of the second drive handle 3.3 is connected to the automatic linkage. The first drive handle 1 and the second drive handle 3.3 are placed horizontally diagonally to avoid interference, ensuring the braking system is in a state of equilibrium. Figure 1 The brake position is shown.

[0056] When the pumping unit needs to be started, the automatic linkage drives the sleeve 3.1 to rotate via the second drive handle 3.3. At this time, the first drive handle 1 and the column cam 2 are fixed, and the push plate 4.1 is driven by the sleeve 3.1 to rotate together, causing the transmission column 4.2 to move from the shallow point to the deep point of the variable depth surface 2.2. Under the action of the return spring 8, the movable brake pad 7 and the push plate 4.1 retract together, releasing the brake and pulling down the power switch to start the pumping unit.

[0057] When the pumping unit needs to be shut down, the power switch is turned off, and the automatic linkage drives the sleeve 3.1 to rotate through the second drive handle 3.3, causing the transmission column 4.2 to move from the deep point to the shallow point of the variable depth surface 2.2. The movable brake pad 7 and the push plate 4.1 are pushed out together, and the movable brake pad 7 contacts the brake disc to achieve braking.

[0058] When manual operation is required, the self-locking characteristic of the automatic linkage makes the second drive handle 3.3 and sleeve 3.1 fixed. The bolts on the first drive handle 1 are removed, and the first drive handle 1 is rotated. The column cam 2 rotates, changing the contact state between the variable depth surface 2.2 and the transmission column 4.2, thus adjusting the brake. Figure 1 , Figure 2 As shown, after adjustment, fix the first drive handle 1 to the frame.

[0059] It should be noted that the automated linkage is existing technology, including a motor, a worm gear reducer, and a crank-rocker mechanism, which can drive the second drive handle 3.3 to rotate 90°. The self-locking characteristic of the worm gear reducer fixes the second drive handle 3.3, which is clear to those skilled in the art.
