Embodiment Construction

[0015] Referring to the accompanying drawings, the present invention is a high-pressure automatic control power oil tank for steel bar upsetting equipment, which includes a main engine 1 and a power oil tank 2, and the main engine 1 is equipped with a working device 3, a pressure gauge 4, a reversing valve 5 and a reset valve. Switch 6, motor 7, main pump 8, auxiliary pump 9, two-position solenoid valve 10 and hydraulic control check valve 11 are housed in power oil tank 2.

[0016] The pressure gauge 4 is a magnetic-assisted two-upper limit electric contact pressure gauge, and the pressure gauge 4 outputs a control signal. The reversing valve 5 is a three-position reversing valve, and the reversing valve 5 is connected with the main pump 8 . The two-position solenoid valve 10 and the hydraulic control check valve 11 are connected with the auxiliary pump 9 . The two-position solenoid valve 10 controls the oil circuit to drive the hydraulic control check valve 11 to realize sy...

Abstract

The invention relates to a high pressure automatic power control gasoline tank for reinforcing steel bar device, it includes a host machine assembled with an action device and power gasoline tank assembled with engine and primary pump. The host machine is also assembled with pressure meter, reversing valve and reset switch, the pressure meter is magnetism double-upper limits contact pressure meter, the pressure meter outputs control signal, the reversing valve is connected to the primary pump. The power gasoline tank is also assembled with a assistant pump, two-bit electromagnetism valve and liquid control single-way valve, the electromagnetism valve and the liquid control single-way valve are connected to the assistant pump, the electromagnetism valve control oil channel drives the liquid control single-way valve to realize system relief, when the system is in failure, the pressure meter sends out the second upper limit signal, cuts off the primary pump power through control circuit. The assistant pump uses method for supplying oil in branches by the primary pump. The flow of the assistant pump is 10-15% of the primary pump; it simplifies the pump structure and reduces the cost.

Description

technical field [0001] The invention relates to steel bar upsetting equipment, in particular to a high-pressure automatic control power oil tank for steel bar upsetting equipment. Background technique [0002] The upsetting straight thread connection of steel bars has attracted extensive attention in the construction industry because of its advantages of high connection strength, stable quality, convenient on-site management and control, and fast construction speed, and has been applied in a series of major projects. [0003] Although the straight thread connection of steel bar upsetting has been applied, the process of steel bar upsetting is controlled by the operator on site according to the output pressure of the power tank or oil pump during upsetting, that is, the end of the upsetting process is artificially controlled by the operator according to the reading of the pressure gauge. Control, due to the pulsation of the output pressure of the oil pump, the pointer of the ...
