Problems solved by technology

[0005] The purpose of the present invention is to provide a new type of hydraulic control system for crawler mobile station in order to solve the above problems, to solve the problem that the existing hydraulic control system fails to store and recover the high-pressure oil, but directly High-pressure oil is discharged into the oil tank, which is not conducive to energy saving, resulting in high fuel consumption of the entire crawler mobile crushing station

Embodiment 1

[0038] Embodiment one: if Figure 5 As shown, the cup body 31 is provided with two cylinders 7 nested together. The cylinders 7 are made of hard materials and are not easily deformed after being pressed. The central axis of the two cylinders 7 coincides with the central axis of the cup 31. , the lower ends of the two cylinders 7 are sealed by the bottom of the cup. The method of sealing can be either by using the cup cover 32 to press the cylinder 7 on the bottom of the cup, or by setting a slot on the bottom of the cup, and then placing the cylinder The lower end of 7 is tightly inserted in the slot, so that the lower end of the cylindrical body 7 is sealed. In addition, a socket with a slot can also be placed at the bottom of the cup, and then the lower end of the cylindrical body 7 is inserted into the slot of the socket. Realize the function that the lower ends of the two barrels 7 are hermetically sealed by the bottom of the cup.

Embodiment 2

[0043] Embodiment two: if Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the sealing ring 19 is replaced by a sealing sleeve 13, and the inner and outer walls of the sealing sleeve 13 are crimped and sealed with the outermost cylinder body 7 and the inner wall of the cup body 31.

Embodiment 3

[0044] Embodiment three: as Figure 7 As shown, the difference between the present embodiment and the second embodiment is that the cylinder body 7 is easily deformed after being pressed. The inner and outer walls are close to the anti-pressure cylinder 9 of the two cylinders 7, and the anti-pressure cylinder 9 and the sealing sleeve 13 are flush, so that when the sealing sleeve 13 squeezes the cylinder 7, the existence of the anti-pressure cylinder 9 can prevent The cylinder body 7 is deformed to ensure that the sealing sleeve 13 is well sealed and crimped with the outermost cylinder body 7 and the inner wall of the cup body 31 .

Abstract

The invention discloses a hydraulic control system for a crawler-type mobile station. The hydraulic control system involves a filter with an energy storage function, wherein the filter communicates with an oil drain opening of a pressure control valve mounted on a hydraulic oil way of the crawler-type mobile station, an oil outlet of the filter communicates with an energy accumulator through a pipeline I, and the pipeline I communicates with the hydraulic oil way through a pipeline II. The hydraulic control system for the crawler-type mobile station has the beneficial effects that the hydraulic control system for the crawler-type mobile station has an energy storage and recovery function, the hydraulic control system can carry out energy storage and recovery treatment on high-pressure oilin the hydraulic control oil way, then compensation is carried out on the hydraulic control oil way when the oil pressure of the hydraulic control oil way drops, and therefore the oil pressure stability of the oil way is maintained, and the normal work of the crawler-type mobile crushing station is facilitated, and meanwhile, the energy-saving effect is remarkable, and the oil consumption of a crusher is effectively reduced; and the size is small, the installation and the arrangement are flexible and convenient, and the practicability is high.

Description

technical field [0001] The invention relates to the field of crawler mobile stations, in particular to a hydraulic control system for crawler mobile stations. Background technique [0002] Crawler Crusher, also known as crawler mobile crushing station, hydraulically driven crawler mobile crushing station, is a kind of high-efficiency crushing equipment, which is self-driven and has complete functions. It has excellent station mobility and adaptability to the work site. It does not require various preliminary preparations before the fixed crushing station is installed. It can complete the station adjustment in a short time and enter the working state at any time. This can reduce the handling of materials and facilitate the coordination of all auxiliary machinery and equipment, especially suitable for operations in narrow and complex areas. [0003] At present, the crawler mobile crushing station generally adopts the hydraulic control system to control the various actuators t...
