The speed of pulling the valve core is slow due to the reasons, and the valve core and the valve sleeve are easy to damage.

Application number 2017214523189, a specialized tool is pulled out to hydraulic valve core is disclosed, including can insert the section of thick bamboo of pulling out in case central pore and pull out the pole, place in the pulling out the pole in the section of thick bamboo of pulling out and can reciprocate, the head and the cavity gland of pulling out the section of thick bamboo are connected, the afterbody is connected with the load base, it has a radial guide way to open on the load base, be equipped with a pair of rather than sliding fit's pulling out round pin in the guide way, the guide way both ends are provided with limit baffle, it is equipped with reset spring to pull out between round pin and the limit baffle, it makes the edge that the tail end of pulling out the round pin stretches out the load base to pull out the pole to remove downwards through promoting, thereby it shifts out from the valve body to drive the case. Although the device can also realize the extraction of the hydraulic valve core, the possibility of possible damage to the valve core exists in the using process.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the speed of pulling out to hydraulic pressure case is slow, fragile case, valve barrel scheduling problem provide a device is swiftly pulled out to hydraulic support case.

The utility model adopts the following technical scheme:

the utility model provides a device is swiftly pulled out to hydraulic support case, includes the loop bar, the one end of loop bar is equipped with the sleeve that matches with the tip of case, be equipped with the internal thread that matches with the external screw thread of case tip in the sleeve, the other end of loop bar is equipped with the outer hexagonal end of interior hexagonal hole assorted with the tip of case, is equipped with handle and base on the loop bar, and the handle is located the sleeve below, and the base is located the top of outer hexagonal end, is equipped with the hammer that gets rid of that can follow loop bar reciprocating motion between handle and the base.

Further, the axes of the sleeve, the swinging hammer and the sleeve rod are located on the same straight line.

Furthermore, the handle is a cross handle and is vertical to the loop bar.

Furthermore, the cross section of the base is circular, and the diameter of the base is larger than that of the drop hammer.

Further, the center of the base coincides with the center of the loop bar.

The utility model has the advantages as follows:

1. the utility model discloses simple structure, convenient to use.

2. The utility model discloses a get rid of hammer reciprocating motion's kinetic energy and drive that the case is whole to move outward, both can easily pull out a case.

3. The utility model discloses a get rid of hammer and loop bar axis direction and case axis unanimous for the case atress is even, has solved the atress uneven and has leaded to the case to be difficult to the problem of taking out in the valve barrel position inequality, has greatly improved the speed and the case integrity of pulling out the case.

4. Through using the utility model discloses, work efficiency has been improved.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic perspective view of the present invention;

wherein: 1-loop bar; 2-a sleeve; 3-external hexagonal end; 4-a handle; 5-a base; 6-throwing hammer.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in the figure, the whole hydraulic support valve element quick pulling device is rod-shaped, one end of the hydraulic support valve element quick pulling device is a sleeve with an internal threaded hole, the threaded hole of the sleeve is matched with a threaded hole in the end portion of a valve element, a loop bar is welded in the center of the sleeve in a perpendicular mode, a cross-shaped handle is arranged on the loop bar, a cylindrical throwing hammer is sleeved on a loop bar under the handle, a circular sheet-shaped base is arranged under the loop bar, the diameter of the round flaky base is not smaller than the diameter of the throwing hammer, the throwing hammer can reciprocate between the cross-shaped handle and the circular sheet-shaped base, an external hexagonal surface is welded at the end of the round flaky base perpendicular to the center of the loop bar, and the size of the external hexagonal surface is matched with a hexagonal hole in the end portion of the valve element.

The using method comprises the following steps: when the tool is used, the outer hexagon at one end of the tool is sleeved into the hexagonal opening in the valve core, the cross-shaped handle is convenient for twisting the valve core to enable the threaded opening of the valve core to be completely separated from the valve sleeve, the sleeve with the inner threaded opening at the other end is twisted on the threaded opening of the valve core, the swinging hammer is driven to reciprocate on the cross-shaped handle and the circular gasket at a certain speed by hands, the kinetic energy of the reciprocating motion of the swinging hammer is utilized to drive the valve core to move outwards integrally, the valve core can be pulled out easily, the axial direction of the swinging hammer and the sleeve rod is consistent with the axial direction of the valve core, the stress of the valve core is uniform, the problem that the valve core is not exactly positioned in the valve sleeve and is difficult to take out due to uneven stress is solved, and the speed of pulling the valve core and the integrity of the valve core are greatly improved.

Through using the utility model discloses, greatly improved case speed of pulling out and case integrity, change the case time and dropped to every 5 minutes by original every 20 minutes, promoted support maintenance efficiency, reduced the maintenance degree of difficulty.

One person can be saved in the daily maintenance of the support, the average wage of a fully mechanized mining team is 593 yuan per person per shift, the monthly labor cost can be saved by 1.779 ten thousand yuan, the damage of the valve core caused by improper operation of pulling the valve core is reduced, and the maintenance efficiency of the support is effectively improved.
