Description

Technical Field

[0001] This utility model relates to the field of pipe pile production, and more particularly to the field of brake hydraulic devices, specifically a device for realizing the pumping and adjusting of the brake horn hydraulic pressure. Background Technology

[0002] In the existing technology, after the ram horn is adjusted to a suitable height, the height of the ram horn is maintained by the self-braking function of the motor. This method has poor reliability. The amount of material loaded in the tube mold is maintained entirely by the motor brake. Once the motor brake fails, safety accidents are likely to occur. In addition, during the pumping process, the motor brake is prone to failure and the transmission mechanism is prone to damage due to the impact of the pump tube. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for pumping and adjusting the hydraulic pressure of the saddle brake that meets the requirements of energy saving, safety and stability and has a wide range of applications.

[0004] To achieve the above objectives, the device for pumping and adjusting the hydraulic pressure of the swashplate brake in this invention is as follows: The device for pumping hydraulic pressure for adjusting the swashplate brake is characterized by comprising a motor, an oil pump, a center block, an oil tank, a pressure sensor, a diaphragm accumulator, a check valve, a bidirectional normally closed solenoid valve, and a bidirectional normally open solenoid valve. The center block is installed between the motor and the oil pump, which are respectively connected to the center block by bolts. The center block is fixed to the oil tank, and the oil pump is completely immersed in the hydraulic oil within the tank. The check valve is connected to the output end of the oil pump, and the diaphragm accumulator is connected to the output end of the check valve. One end of the bidirectional normally closed solenoid valve is connected to the output end of the check valve, and the other end is connected to the brake caliper. One end of the bidirectional normally open solenoid valve is connected to the oil tank, and the other end is connected to the brake caliper. The pressure sensor and the diaphragm accumulator are both mounted on the center block, and the pressure sensor is connected to the diaphragm accumulator.

[0005] Preferably, the device further includes an overflow valve installed at the outlet of the oil pump.

[0006] Preferably, the device further includes a filter screen installed on the oil pump's suction port, through which the oil pump draws in hydraulic oil.

[0007] Preferably, the device further includes a breather cap and a level gauge, which are mounted on the oil tank.

[0008] Preferably, the central block has a central hole in which a coupling is installed, the coupling connecting the motors and oil pumps on both sides.

[0009] Preferably, the device further includes a first valve block and a second valve block, both of which are mounted on the center block.

[0010] Preferably, when the device is hydraulically braked after the height of the horn mechanism is adjusted, the electromagnet of the bidirectional normally closed solenoid valve is energized and engaged, the valve core of the bidirectional normally closed solenoid valve is in the right position, and the bidirectional normally closed solenoid valve is in the conducting state; the electromagnet of the bidirectional normally open solenoid valve is energized and engaged, the valve core of the bidirectional normally open solenoid valve is in the right position, and the bidirectional normally open solenoid valve is in the closed state. The oil pump draws hydraulic oil from the filter, pressurizes it to become high-pressure oil, and transmits it to a check valve. The check valve directs most of the high-pressure oil into the diaphragm accumulator and a small portion of the high-pressure oil through the right-hand position of the bidirectional normally closed solenoid valve into the brake caliper, causing the brake caliper to tighten slowly. If the oil pressure in the diaphragm accumulator reaches the set value, the motor and oil pump stop rotating, and the brake caliper is clamped by the diaphragm accumulator. If the oil pressure in the diaphragm accumulator is lower than the set value, the motor drives the oil pump to start and replenish the pressure in the diaphragm accumulator.

[0011] Preferably, when the device is hydraulically released, the electromagnet of the bidirectional normally closed solenoid valve is not energized, the valve core of the bidirectional normally closed solenoid valve is in the left position, and the bidirectional normally closed solenoid valve is in the closed state; the electromagnet of the bidirectional normally open solenoid valve is not energized, the valve core of the bidirectional normally open solenoid valve is in the left position, and the bidirectional normally open solenoid valve is in the open state. The bidirectional normally open solenoid valve allows high-pressure oil to flow into the oil tank, releasing the brake caliper.

[0012] The device for pumping and adjusting the hydraulic pressure of the brake caliper, as described in this invention, ensures stable and safe braking force over a long period through the cooperation of an accumulator and a switching valve. The accumulator prevents frequent motor starts and stops, saving energy and extending the service life of the motor and oil pump. Attached Figure Description

[0018] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.

[0019] This utility model discloses a device for pumping hydraulic pressure for adjusting the swashplate, comprising a motor 1, an oil pump 2, a center block 3, an oil tank 4, a pressure sensor 7, a diaphragm accumulator 8, a one-way valve 3-1, a bidirectional normally closed solenoid valve 6-1, and a bidirectional normally open solenoid valve 6-2. The center block 3 is installed between the motor 1 and the oil pump 2, and the motor 1 and the oil pump 2 are respectively connected to the center block 3 by bolts. The center block 3 is fixed to the oil tank 4, and the oil pump 2 is completely immersed in the hydraulic oil in the oil tank 4. The one-way valve 3-1 is connected to the oil... The output end of pump 2 is connected, the diaphragm accumulator 8 is connected to the output end of check valve 3-1, one end of bidirectional normally closed solenoid valve 6-1 is connected to the output end of check valve 3-1, and the other end of bidirectional normally closed solenoid valve 6-1 is connected to brake caliper. One end of bidirectional normally open solenoid valve 6-2 is connected to oil tank 4, and the other end of bidirectional normally open solenoid valve 6-2 is connected to brake caliper. The pressure sensor 7 and diaphragm accumulator 8 are both mounted on center block 3, and the pressure sensor 7 is connected to diaphragm accumulator 8.

[0020] In a preferred embodiment of the present invention, the device further includes an overflow valve 3-2, which is installed at the outlet of the oil pump 2.

[0021] In a preferred embodiment of the present invention, the device further includes a filter screen 2-1, which is installed on the oil inlet of the oil pump 2, and the oil pump 2 draws in hydraulic oil through the filter screen 2-1.

[0022] In a preferred embodiment of the present invention, the device further includes a breather cover 4-1 and a level gauge 4-2, which are mounted on the oil tank 4.

[0023] In a preferred embodiment of the present invention, the central block 3 has a central hole, and a coupling is installed in the central hole. The coupling connects the motor 1 and the oil pump 2 on both sides.

[0024] In a preferred embodiment of the present invention, the device further includes a first valve block 5 and a second valve block 6, both of which are mounted on the center block 3.

[0025] In a preferred embodiment of this utility model, when the device is hydraulically braked after the height of the horn mechanism is adjusted, the electromagnet of the bidirectional normally closed solenoid valve 6-1 is energized and engaged, the valve core of the bidirectional normally closed solenoid valve 6-1 is in the right position, and the bidirectional normally closed solenoid valve 6-1 is in the conducting state; the electromagnet of the bidirectional normally open solenoid valve 6-2 is energized and engaged, the valve core of the bidirectional normally open solenoid valve 6-2 is in the right position, and the bidirectional normally open solenoid valve 6-2 is in the closed state. The oil pump 2 draws hydraulic oil from the filter screen 2-1, pressurizes the hydraulic oil to become high-pressure oil, and transmits the high-pressure oil to the one-way valve 3-1. The one-way valve 3-1 directs most of the high-pressure oil into the diaphragm accumulator 8 and a small portion of the high-pressure oil through the right position of the bidirectional normally closed solenoid valve 6-1 into the brake caliper, causing the brake caliper to tighten slowly. If the oil pressure in the diaphragm accumulator 8 reaches the set value, the motor 1 and the oil pump 2 stop rotating, and the brake caliper is clamped by the diaphragm accumulator 8. If the oil pressure in the diaphragm accumulator 8 is lower than the set value, the motor 1 drives the oil pump 2 to start and replenish the pressure in the diaphragm accumulator 8.

[0026] In a preferred embodiment of this utility model, when the device is hydraulically released, the electromagnet of the bidirectional normally closed solenoid valve 6-1 is not energized, the valve core of the bidirectional normally closed solenoid valve 6-1 is in the left position, and the bidirectional normally closed solenoid valve 6-1 is in the closed state; the electromagnet of the bidirectional normally open solenoid valve 6-2 is not energized, the valve core of the bidirectional normally open solenoid valve 6-2 is in the left position, and the bidirectional normally open solenoid valve 6-2 is in the open state. The bidirectional normally open solenoid valve 6-2 guides high-pressure oil into the oil tank, releasing the brake caliper.

[0027] This utility model belongs to the pipe pile manufacturing industry. It is applied to the use of a braking hydraulic device to fix the height of the pump horn at a certain position after adjusting the height of the pump horn, so that the entire horn adjustment equipment can be used safely.

[0028] This invention provides a hydraulic brake caliper braking method. After the swivel height is adjusted, the hydraulic brake caliper distributes the force of the swivel transmission mechanism to the brake caliper, which improves the reliability and safety of the swivel mechanism and extends its service life.

[0029] like Figure 1 As shown, a central block 3 connects motor 1 and oil pump 2. Motor 1 and oil pump 2 are connected to central block 3 by bolts. Central block 3 has a central hole with a coupling installed inside. Motor 1 and oil pump 2 are connected through the coupling. Central block 3 is fixed to oil tank 4. Oil pump 2 is completely immersed in the hydraulic oil in oil tank 4. A filter screen 2-1 is installed on the oil suction port of oil pump 2. Oil tank 4 is equipped with a breather cover 4-1 and a level gauge 4-2. Central block 3 is equipped with a check valve 3-1, an overflow valve 3-2, a first valve block 5, a second valve block 6, a bidirectional normally closed solenoid valve 6-1, a bidirectional normally open solenoid valve 6-2, a pressure sensor 7, and a diaphragm accumulator 8.

[0030] Among them, the first valve block 5 and the second valve block 6 are different things. The function of the first valve block 5 is to act as a transition plate for the oil circuit. Its main function is to raise the second valve block 6 and prevent the components on the second valve block 6 from interfering with other parts.

[0031] The second valve block 6 is a machined part with internal oil passages conforming to hydraulic principles. The bidirectional normally closed solenoid valve 6-1 and the bidirectional normally open solenoid valve 6-2 are purchased standard hydraulic valve parts. The installation dimensions of the second valve block 6 are machined according to the dimensions of the bidirectional normally closed solenoid valve 6-1 and the bidirectional normally open solenoid valve 6-2. The bidirectional normally closed solenoid valve 6-1 and the bidirectional normally open solenoid valve 6-2 are installed on the second valve block 6, together forming the hydraulic function for this part.

[0032] In a specific embodiment of this utility model, the operation process is as follows: S1: Hydraulic braking is applied after the yoke mechanism is adjusted to the correct position.

[0033] After the steering horn mechanism is adjusted to the appropriate position, the hydraulic brake caliper closes, locking the steering horn mechanism.

[0034] The specific hydraulic operation is described below: When braking, the electromagnet of the bidirectional normally closed solenoid valve 6-1 is energized and engaged, the valve core of the bidirectional normally closed solenoid valve 6-1 is in the right position, and the bidirectional normally closed solenoid valve 6-1 is in the conducting state; the electromagnet of the bidirectional normally open solenoid valve 6-2 is energized and engaged, the valve core of the bidirectional normally open solenoid valve 6-2 is in the right position, and the bidirectional normally open solenoid valve 6-2 is in the closed state.

[0035] Hydraulic oil pump 2 draws hydraulic oil from filter screen 2-1, pressurizes it, and sends it to check valve 3-1. Most of the high-pressure oil flows into diaphragm accumulator 8, while a small portion flows into the brake caliper through the right-hand side of bidirectional normally closed solenoid valve 6-1, causing the brake caliper to slowly tighten. When the oil pressure in diaphragm accumulator 8 reaches the set value of pressure sensor 7, motor 1 and hydraulic pump 2 stop rotating. The brake caliper is clamped by the oil supplied from diaphragm accumulator 8, at which point the brake caliper pressure reaches its maximum. Relief valve 3-2 is used to limit the maximum oil pressure at the outlet of hydraulic pump 2 to prevent the oil pressure from exceeding the set value. When pressure sensor 7 detects that the oil pressure in the diaphragm accumulator 8 is lower than the set pressure, motor 1 drives hydraulic pump 2 to start and replenish the pressure in diaphragm accumulator 8. A full diaphragm accumulator 8 can satisfy several clamping and releasing cycles of the brake caliper, avoiding frequent motor starts and reducing energy consumption.

[0036] S2: Release of hydraulic brake on the yoke mechanism.

[0037] When braking, the electromagnet of the normally closed bidirectional solenoid valve 6-1 is not energized, the valve core of the normally closed bidirectional solenoid valve 6-1 is in the left position, and the normally closed bidirectional solenoid valve 6-1 is in the closed state; the electromagnet of the normally open bidirectional solenoid valve 6-2 is not energized, the valve core of the normally open bidirectional solenoid valve 6-2 is in the left position, and the normally open bidirectional solenoid valve 6-2 is in the conducting state.

[0038] At this moment, the high-pressure oil in the brake caliper flows into the oil tank from the open position of the two-way normally open solenoid valve 6-2, and the brake caliper is released, losing braking force.

[0039] Pressure sensors can be replaced by pressure relays; pressure gauges with electrical contacts are also within this protection range.

[0040] If the valve core model of the normally closed solenoid valve 6-1 or the bidirectional normally open solenoid valve 6-2 is changed, or the valve core function is changed, as long as the same effect is achieved, it will be covered by this protection.
