Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic pilot valve devices, in particular to an assembly device for an electromagnetic pilot valve of a hydraulic support. Background Technique

[0002] At present, electro-hydraulic control valves have been comprehensively adopted in the fully-mechanized mining hydraulic supports underground in the construction of intelligent coal mines. The electro-hydraulic control valves on the working face need to be regularly maintained. The number of electro-hydraulic control valves to be maintained on the working face of the hydraulic support is gradually increasing, and the demand for the maintenance work of intelligent equipment is increasing year by year.

[0003] The assembly efficiency of the electromagnetic pilot valve on the electro-hydraulic control main valve is low. Especially for the process of placing the ceramic balls under the liquid-moving part's liquid-passing sleeve, it greatly restricts the assembly efficiency. Currently, during assembly, medical forceps are used to pick up one by one ceramic balls with a diameter of 3 mm and put them into the groove at the cross-shaped opening position of the liquid-passing sleeve (23 mm away from the thread opening) through the shell sealing plug (inner thread hole diameter 12 mm). Often, the balls cannot be directly placed in the groove, but may be placed on the edge of the groove or on the cross-shaped groove, or even adsorbed onto the shell beside the liquid-passing sleeve. Then, the forceps are used to move the ceramic balls into the groove. This method greatly restricts the maintenance efficiency. Therefore, the utility model provides an assembly device for an electromagnetic pilot valve of a hydraulic support to solve the deficiencies in the prior art. Summary of the Utility Model

The hollow column 2 is installed on the fixed block 7. A pressing rod 3 is movably arranged inside the hollow column 2. A vertical slideway 8 is arranged inside the device main body 1. The lower end of the pressing rod 3 is located inside the vertical slideway 8. A limiting groove 9 is arranged inside the device main body 1 on one side of the vertical slideway 8. A blanking slideway 10 is arranged inside the device main body 1 on the other side of the vertical slideway 8. The limiting groove 9 is vertically arranged with the vertical slideway 8. The blanking slideway 10 is inclined, and the upper end of the blanking slideway 10 is communicated with the lower discharge port of the funnel-shaped hopper 4. The lower end of the blanking slideway 10 and one end of the limiting groove 9 are both connected to the vertical slideway 8. A stopper 5 is arranged inside the limiting groove 9. The position of the discharge end of the blanking slideway 10 is adapted to the position of the stopper 5. A feeding nozzle 6 is arranged below the inside of the device main body 1. The lower end of the vertical slideway 8 is communicated with the feeding channel inside the feeding nozzle 6.

[0019] When performing the assembly operation of the ceramic ball of the hydraulic support electromagnetic pilot valve, move the whole device so that the feeding nozzle 6 reaches the position of the inner groove of the cross port of the liquid-passing sleeve of the electromagnetic pilot valve spool to be installed. Press the pressing rod 3 downward with a finger. The pressing rod 3 inside the hollow column 2 will move downward to press a ceramic ball stuck on the stopper 5 and automatically move downward through the stopper 5. The ceramic ball enters the feeding nozzle 6 through the vertical slideway 8 and then reaches the inner groove of the cross port of the liquid-passing sleeve to be installed. Release the pressing rod 3, and the pressing rod 3 will reset under the action of the first spring 13. The stopper 5 will also reach its original position to play a limiting role. The next ceramic ball will slide to the position of the stopper 5 due to gravity and be stuck by the stopper 5 and will not fall, realizing the installation step of one ceramic ball and preparing for the prelude of the installation of the next ceramic ball, thereby realizing the precise and continuous assembly of the ceramic ball.

[0020] On one side of the top of the device main body 1, there is a threaded connection seat 11. The outer wall of the hopper mouth of the funnel-shaped hopper 4 is threadedly connected to the threaded connection seat 11. A transition blanking channel 12 is arranged below the inside of the threaded connection seat 11. The upper end of the transition blanking channel 12 is butted against the hopper mouth of the funnel-shaped hopper 4, and the lower end of the transition blanking channel 12 is butted against the upper end of the blanking slideway 10. By detachably installing the funnel-shaped hopper 4, the funnel-shaped hopper 4 can be disassembled for unclogging operation when it is blocked inside the funnel-shaped hopper 4.

[0021] The upper end of the pressing rod 3 extends out of the top end of the hollow column 2 and a first spring 13 is sleeved outside. The upper end of the first spring 13 is connected to the bottom of the pressing block on the top of the pressing rod 3, and the lower end of the first spring 13 is connected to the top of the hollow column 2.
