Description

Technical Field

[0001] The utility model relates to the technical field of belt-type oil pumping units, in particular to a brake locking protection device for belt-type oil pumping units. Background Art

[0002] The brake device of the oil pump is a very important operating control device. Whether its braking performance is flexible and reliable plays a decisive role in the safety of various operations of the oil pump. As a type of oil pump, the belt-type oil pump has outstanding advantages and is widely used. Figure 1 A partial device of a belt-type oil pumping unit body 13 is shown, which includes a brake device, which includes a brake pad, a brake disc, a spring tube, a brake lever 16, a brake handle 14, a stop plate 15, a brake base 19, etc. A brake base fixing bolt 20 is fixed in the middle of the brake base 19. The brake handle 14, the stop plate 15 and the brake lever 16 are connected together through two fan-shaped structures 17 arranged in parallel, and two symmetrical circular holes 18 are arranged at one end of the two fan-shaped structures 17. When braking, pressing the brake handle 14 drives the brake lever 16 to rotate. The brake lever 16 drives the brake pad to hold the brake disc tightly through the spring tube fixed at the end to achieve braking. When the stop plate 15 touches the brake base 19, the brake lever 16 is formed to move to a dead point and the brake is locked.

[0003] The above-mentioned belt-type oil pump brake device has low reliability in the braking state and the brake release state due to the lack of a dedicated locking protection device. When the operator is not concentrating, misoperation can easily cause a slipping accident, posing a safety hazard to the safe production of employees and enterprises. Therefore, designing a belt-type oil pump brake locking protection device is the best choice.

[0004] There are also various types of belt-type oil pump brake locking protection devices. After preliminary understanding, the Chinese utility model patent applications with announcement number CN208935228U, announcement date 2019.06.04 and announcement number CN215108860U, announcement date 2021.12.10 disclose two types of belt-type oil pump brake self-locking protection devices, which respectively realize the self-locking state of the belt-type oil pump brake through the ratchet and gear rack structure. However, both structures require the modification of the existing belt-type oil pump brake device, which is complex in structure and cannot achieve the locking of the belt-type oil pump brake device when the brake is released. Utility Model Content

[0005] The utility model aims to provide a belt-type oil pump brake locking protection device, which has a simple structure, reliable locking and is easy to use, and is used to solve the problem that the existing belt-type oil pump brake locking protection device requires the entire brake device to be modified and has a complex structure.

[0006] The utility model discloses a brake locking protection device for a belt-type oil pump, which adopts the following technical scheme: a brake locking protection device for a belt-type oil pump, comprising a holder mounted on a brake base, the holder being provided with a locking member for stopping the brake lever from rotating when the belt-type oil pump is in a brake state, and the holder being further provided with a latch member for being inserted and matched with a circular hole on a fan-shaped structure when the brake of the belt-type oil pump is in a released state.

[0007] The belt-type oil pump brake locking protection device of the utility model is improved on the basis of the existing belt-type oil pump brake device. When the belt-type oil pump brake locking protection device of the utility model is in use, after the belt-type oil pump brake is stopped, the socket of the utility model is clamped on the brake base, and the locking piece on the socket locks the brake lever to prevent rotation, so that the brake handle is limited and locked, thereby improving the reliability of the locking protection of the brake device; when the belt-type oil pump is started and operated, the socket of the utility model is clamped on the brake base, and the latch is inserted into the round hole on the fan-shaped structure at the end of the brake handle to limit and lock the brake handle, thereby eliminating the safety hazard caused by misoperation.

[0008] Furthermore, the holder is a U-shaped holder, the opening of the U-shaped holder faces the extension direction of the brake base, an avoidance groove for avoiding the fixing bolts of the brake base is provided on the U-shaped holder, and the two wing plates of the U-shaped holder fit the brake base. The holder is a U-shaped holder, and the opening of the U-shaped holder faces the extension direction of the brake base. This arrangement is structurally stable and saves materials. The U-shaped structure is more conveniently arranged on the brake base. The fixing bolts of the brake base are inserted into the avoidance groove to limit the left and right movement of the holder. The arrangement of the avoidance groove also allows the two wing plates of the U-shaped holder to fit better with the brake base, and the structure is compact, so as to achieve a better fixing effect.

[0009] Furthermore, a fixing bolt for fixing the brake base and keeping the U-shaped base and the brake base locked and fixed is screwed on the wing plate of the U-shaped seat. Tightening the fixing bolt fixes the U-shaped seat on the brake base, ensuring that the locking member and the latch member are more stable and reliable when locking the brake device.

[0010] Furthermore, a through hole is provided on the wing plate of the U-shaped seat, and a fixing nut is welded on the wing plate at a position corresponding to the through hole, and the inner hole of the fixing nut constitutes a screw hole for screwing the fixing bolt. The through hole is provided on the wing plate of the U-shaped seat, and the manufacturing is simple and convenient, and the fixing nut is adjusted by the fixing bolt, which is simple and has a good locking effect.

[0011] Furthermore, the locking member is a stopper rod extending horizontally and perpendicular to the brake lever, and the stopper rod is adjustably arranged on the U-shaped seat. When the belt-type oil pump is in a braking state, the stopper rod blocks the brake lever forward to stop the brake lever from rotating, and the stopper rod is released when it is retracted to the rear side of the brake lever. By blocking the stopper rod forward above the brake lever to limit the rotation of the brake lever, the brake device is locked, which is simple to operate and has a good locking effect.

[0012] Furthermore, a vertical plate perpendicular to the wing plate and parallel to the brake lever is provided on the U-shaped seat, a through hole is provided on the vertical plate, a limit nut is welded on the wing plate at a position corresponding to the through hole, the stop rod is a limit bolt, and the inner hole of the limit nut constitutes a screw hole for screwing the limit bolt. The through hole provided on the vertical plate is simple and convenient to manufacture, and the limit nut is adjusted in coordination with the limit bolt, which is simple and has a good locking effect.

[0013] Furthermore, the latch is an L-shaped pin, which is arranged on the side of the U-shaped seat opposite to the vertical plate. The L-shaped pin has a simple structure, and the L-shaped pin arranged on the side opposite to the vertical plate does not affect the limit bolt, making the structure more convenient.

[0014] Furthermore, a rib plate is connected between the vertical plate and the U-shaped seat wing plate, which ensures that the vertical plate structure is more stable and the limiting bolt has a better limiting and locking effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0022] Specific embodiment 1 of the brake locking protection device of the belt-type oil pumping unit of the utility model:

[0023] The utility model of the belt type oil pumping unit brake locking protection device is as follows Figure 2-5 As shown, a belt-type oil pump brake locking protection device includes a socket mounted on a brake base 19, on which is provided a locking member for stopping the brake lever 16 from rotating when the belt-type oil pump is in a brake state, and on which is also provided a latch member for inserting and cooperating with a circular hole 18 on a fan-shaped structure 17 when the brake of the belt-type oil pump is in a released state.

[0024] As can be seen from the figure, the base is a U-shaped base 1, which includes two rectangular wing plates that are parallel to the upper and lower surfaces of the brake base 19 and match in size. The opening of the U-shaped base 1 is facing the extension direction of the brake base 19, and U-shaped grooves 2 are symmetrically opened on the upper and lower wing plates of the U-shaped base 1. The U-shaped grooves 2 are consistent with the opening direction of the U-shaped base 1. When the U-shaped base 1 is clamped on the brake base 19, the brake base fixing bolts 20 are just clamped into the U-shaped grooves 2, and the brake base fixing bolts 20 limit the left and right movement of the U-shaped base 1. At this time, the two wing plates of the U-shaped base 1 fit the brake base 19.

[0025] Specifically, a T-shaped fixing bolt 12 is provided on one side of the upper wing plate of the U-shaped seat 1, which can fix the U-shaped seat 1 to the brake base 19. The T-shaped fixing bolt 12 includes a screw rod and a circular handle assembled with the screw rod. A square vertical plate 3 is provided on the other side edge of the upper wing plate, which is perpendicular to the wing plate and parallel to the brake lever 16. A T-shaped limit bolt 8 is provided on the vertical plate 3, which is perpendicular to the vertical plate 3. The T-shaped limit bolt 8 includes a screw rod and a circular handle assembled with the screw rod. The T-shaped limit bolt 8 is the locking member. Two right-angled triangular ribs are provided on both sides of the vertical plate 3, which are perpendicular to the vertical plate 3, namely the first rib plate 4 and the second rib plate 5, to ensure that the vertical plate 3 is more stable. An L-shaped through pin 9 matching the circular hole 18 on the fan-shaped structure 17 is provided at the rear end of the U-shaped groove 2 in the middle of the lower wing plate. The L-shaped through pin 9 is the latch member.

[0026] Specifically, a T-shaped limit bolt through hole 6 is provided in the middle portion of the upper part of the vertical plate 3, and a concentric regular hexagonal limit nut 7 is welded at a position on the vertical plate 3 corresponding to the T-shaped limit bolt through hole 6. The T-shaped limit bolt 8 can be adjustably screwed into the matching limit nut 7, and the diameter of the T-shaped limit bolt through hole 6 is slightly larger than the diameter of the T-shaped limit bolt 8; a T-shaped fixing bolt through hole 10 is provided on one side of the wing plate of the U-shaped seat 1, and a fixing nut 11 is welded at a position on the wing plate of the U-shaped seat 1 corresponding to the T-shaped fixing bolt through hole 10, and the T-shaped fixing bolt 12 can be adjustably screwed into the matching fixing nut 11, and the diameter of the T-shaped fixing bolt through hole 10 is slightly larger than the diameter of the T-shaped fixing bolt 12.

[0027] like Figure 4As shown, when the belt-type oil pump needs to stop running, the brake handle 14 is pressed down to drive the brake lever 16 and the stop plate 15 to rotate counterclockwise. The brake lever 16 drives the brake pad to hold the brake disc through the spring tube fixed at the end to achieve braking. When the stop plate 15 touches the brake base 19, the brake lever 16 is formed to move to a dead point and the brake is locked. The opening of the U-shaped seat 1 of the utility model faces the brake base 19, and the U-shaped groove 2 faces the brake base fixing bolt 20 and is installed on the brake base 19. The T-shaped fixing bolt 12 is rotated clockwise to fix the U-shaped seat 1 on the brake base 19. The T-shaped limit bolt 8 is rotated clockwise. When the limit bolt 8 extends forward and blocks the brake lever 16, the brake lever 16 is stopped and the brake device is locked. Due to the limit locking function of the T-shaped limit bolt 8 on the brake device in the braking state, the reliability of the locking protection of the brake device is further improved.

[0028] like Figure 5 As shown, when the belt-type oil pump needs to release the brake for normal operation, the brake locking protective device of the belt-type oil pump of the utility model is removed, the brake handle 14 is lifted and returned to its original position, and the brake lever 16 and the stop plate 15 are driven to rotate clockwise. The brake lever 16 drives the brake pad to release the brake disc through the spring tube fixed at the end, and the belt-type oil pump operates normally. The L-shaped through pin 9 of the U-shaped seat 1 of the utility model is placed in the upper direction, the opening of the U-shaped seat 1 is facing the brake base 19, and the U-shaped groove 2 is facing the brake base fixing bolt 20 and then installed on the brake base 19. The L-shaped through pin 9 is inserted into the circular hole 18 on the fan-shaped structure 17 at the end of the brake handle 14, and the T-shaped fixing bolt 12 is rotated clockwise to fix the U-shaped seat 1 on the brake base 19. Due to the limit locking of the brake handle 14 by the L-shaped through pin 9, the misoperation such as pressing the handle is prevented, and the safety hazard is effectively eliminated.

[0029] Through the above description of the specific embodiment 1 of the brake locking protection device of the belt-type oil pumping unit of the utility model, it can be seen that the brake locking protection device of the belt-type oil pumping unit of the utility model is improved on the basis of the existing brake device of the belt-type oil pumping unit, and has a simple structure and reliable locking. When the belt-type oil pumping unit is stopped by braking, the locking member on the holder locks the brake lever to prevent rotation. When the belt-type oil pumping unit is started and operated, the latch member is inserted into the round hole on the fan-shaped structure at the end of the brake handle. The brake device can be locked during braking and operation, thereby improving the reliability of the brake device locking protection and eliminating the safety hazards caused by misoperation.
