Abstract
The utility model discloses a brake oil cylinder for a mine. The brake oil cylinder for the mine is designed to overcome the defects that existing equipment is low in action speed and the like. The brake oil cylinder for the mine comprises a tubular hollow cylinder barrel, a guide sleeve, a cylinder bottom lug ring, a hollow piston rod, a hydraulic control valve, a cylinder sleeve, a head portion lug ring and a spring. A first oil liquid hole which is communicated with a hollow hole of the piston rod is formed in the head portion lug ring and a second oil liquid hole which is connected to the inner side of the cylinder barrel is formed in the cylinder bottom lug ring. The hydraulic control valve and the cylinder sleeve are located inside the cylinder barrel and conduct reciprocal movement along the inner wall of the cylinder barrel under the pushing of the piston rod. The hydraulic control valve is a hydraulic control one-way vale. The spring is a cylindrical spiral compression spring. The brake oil cylinder for the mine is reasonable in structure, convenient to use, light in weight, small in size, quick in action speed, stable and reliable in performance, high in efficiency, and low in cost. In addition, electro-hydraulic integration is realized and the brake oil cylinder for the mine is brought in line with international equivalent equipment for the mine.
Description
Technical field
The utility model relates to a kind of mining brake cylinder, especially relates to the electric overhead trolley brake cylinder of a kind of row.
Background technique
Oil cylinder is the necessary equipment of mining equipment (especially being listed as electric overhead trolley) skidding.No matter existing mining hydraulic brake cylinder is double-action DC type vehicle hydraulic cylinder or HSG * 01 Series Hydraulic cylinder, exists all that oil cylinder weight is large, volume is large, speed is slow, to problems such as the flow rate of hydraulic system requirement are large, can't satisfy the requirement of mining equipment.
The model utility content
In order to overcome above-mentioned defective, the utility model provides a kind of usability better mining brake cylinder.
For achieving the above object, the utility model provides a kind of mining brake cylinder, described oil cylinder comprises the cannulated cylinder barrel, be arranged on the guide sleeve of described cylinder barrel one end inboard, be arranged on the cylinder bottom earrings of the described cylinder barrel the other end, string is located at the hollow piston rod in described guide sleeve, be arranged on hydraulic control valve and cylinder sleeve on described piston rod one side head, be arranged on the head earrings on described piston rod opposite side termination, and be connected between described cylinder bottom earrings and head earrings and be set in the spring in the described cylinder barrel outside; Described head earrings is provided with the first fluid hole that is communicated with the piston rod hollow hole, and described cylinder bottom earrings is provided with the second fluid hole that is connected to the cylinder barrel inboard; Hydraulic control valve and cylinder sleeve are positioned at cylinder barrel, do back and forth movement along inner wall of cylinder under the promotion of piston rod.
Particularly, described hydraulic control valve is Pilot operated check valve.
Particularly, described spring is cylindroid helicalcoil compression spring.
Be provided with Pilot operated check valve in the mining brake cylinder of the utility model, can reach accurately the pressurize effect, make mining equipment safer.Be connected with spring between cylinder bottom earrings and head earrings, utilize spring action to open the fluid-control one-way valve core in the expansive force of head earrings when hydraulic system decompression (i.e. 0 pressure), reach (overhead trolley) walking states.All be provided with the fluid hole on head earrings and cylinder bottom earrings, move to left when getting back to 0 stroke at the hydraulic cylinder pressure relief piston, two fluid holes simultaneously drainings the oil hydraulic cylinder action is fast, the fast purpose of draining to reach.
The mining brake cylinder of the utility model is rational in infrastructure, and is easy to use, lightweight, and volume is little, and quick action is stable and reliable for performance, and efficient is high, and is cheap, realizes electrohydraulic integration, integrates with the equal mining equipment in the world.
Description of drawings
Fig. 1 is the utility model preferred embodiment structural representation.
Fig. 2 is preferred embodiment the first view shown in Figure 1.
Fig. 3 is preferred embodiment the second view shown in Figure 1.
Embodiment
Below in conjunction with Figure of description and preferred embodiment, the utility model is described in detail.
As shown in Figure 1, the mining brake cylinder of the utility model comprises cannulated cylinder barrel 1, be arranged on the guide sleeve 2 of cylinder barrel 1 one end inboards, be arranged on the cylinder bottom earrings 3 of cylinder barrel 1 the other end, string is located at the hollow piston rod 4 in guide sleeve 2, be arranged on hydraulic control valve 5 and cylinder sleeve 6 on piston rod 4 one side heads, be arranged on the head earrings 7 on piston rod 4 opposite side terminations, and be connected between cylinder bottom earrings 3 and head earrings 7 and be set in the spring 8 in cylinder barrel 1 outside.Head earrings 7 is provided with the first fluid hole 11 that is communicated with piston rod 4 hollow holes, and cylinder bottom earrings 3 is provided with the second fluid hole 12 that is connected to cylinder barrel 1 inboard.Hydraulic control valve 5 and cylinder sleeve 6 are positioned at cylinder barrel 1, do back and forth movement along cylinder barrel 1 inwall under the promotion of piston rod 4.
In order to reach more accurately the pressurize effect, to make mining equipment safer, hydraulic control valve adopts Pilot operated check valve.
In order to utilize better expansive force to open the fluid-control one-way valve core when the hydraulic system decompression, spring adopts cylindroid helicalcoil compression spring, and strength is larger, and stability is higher.
As shown in Figures 2 and 3, when oil hydraulic cylinder 0 stroke, mining brake cylinder need to lean on the hydraulic system selector valve to commutate to pressure.When hydraulic system decompression (0 pressure), in order to reach well and accurately pressurize effect, the expansive force that utilizes the exterior cylindrical spiral compression spring to act on the head earrings is opened the fluid-control one-way valve core, reaches (overhead trolley) walking states; Exterior cylindrical spiral compression spring pressurized moves to right piston and makes (overhead trolley) braking.
When new type mining equipment (being listed as electric overhead trolley) required braking, hydraulic system commutated to pressing exterior cylindrical spiral compression spring pressurized by selector valve, and pressure oil liquid moves to right piston by Pilot operated check valve to reach braking.System pressure greater than, equal under the expansive force condition of spiral compression spring, fluid firmly to be pinned.The system electric control Pilot operated check valve that do not commutate is not opened, and more well and accurately reaches the pressurize effect, for mining equipment provides safety guarantee.
When hydraulic system 0 was pressed, the expansive force of spiral compression spring was opened Pilot operated check valve automatically greater than fluid under the hydraulic system pressure condition, and the hydraulic cylinder pressure relief piston moves to left and gets back to 0 stroke.The oil hydraulic cylinder action is fast, the fast new design theory of draining thereby oil hydraulic cylinder head earrings, cylinder bottom earrings while draining reach.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
