Abstract
The utility model relates to a hydraulic smashing pick, which comprises a handle, an upper pick body, an outer cylinder and a lower pick body, wherein, the handle is connected with the upper pick body, and the side surface of the upper pick body is connected with the tail of a soft pipe, and a port plate is arranged inside the upper pick body, and the bottom end of the upper pick body is connected with the upper end of the outer cylinder, and the lower end of the outer cylinder is connected with the lower pick body, and a flow-rate cylinder is sleeved inside the outer cylinder, and the outer circumference of the flow-rate cylinder is provided with a high pressure oil hole, and a piston is sleeved inside the flow-rate cylinder, and the upper part of the piston is provided with a surge direction-changing valve, and the bottom end of the surge direction-changing valve is sealed with the flow-rate cylinder, and the top end of the surge direction-changing valve is sealed with the upper pick body. The smashing pick has the advantages that the integral weight is light, the structure design is reasonable, the malfunction rate is low, and the product stability is good; the sealing between the outer cylinder and the flow-rate cylinder is changed from the movable sealing to the static sealing, so that the outer cylinder is matched with the flow-rate cylinder in a compact way, thereby not only simplifying the processing technic and reducing the cost, but also improving the performance of the product; after the disassembling and assembling for a plurality of times, the smashing function is not changed.
Description
Technical field
The utility model relates to a kind of hydraulic breakup pick.
Background technology
The primary structure of hydraulic breakup pick in the market comprises handle, last pick body, valve plate, hydraulicchange-over valve, piston, flow tube, outer cylinder, following pick body.This light hydraulic breakup pick is when fragmentation, and bounce is big, people's labour intensity height; Hydraulicdirectional control valve fault rate height, crushing efficiency can reduce gradually after use a period of time; And the flow tube of Hydraulic pick and the required precision that cooperatively interacts between the cylinder barrel are higher, often break down in use and keep in repair, and Hydraulic pick is after the maintenance of dismounting repeatedly, crushing efficiency can reduce greatly, not only increased the cost of maintenance, repairing, also production has been impacted.
The utility model content
The purpose of this utility model provides a kind of hydraulic breakup pick, to overcome the shortcoming of said apparatus fault rate height, cost height, unstable properties.
The purpose of this utility model is achieved through the following technical solutions:
The described hydraulic breakup pick of the utility model embodiment, comprise handle, last pick body, outer cylinder and following pick body, the described pick body inside of going up is provided with valve plate, the last pick body side surface flexible pipe tail pigtail that spins, flexible pipe tail pigtail is connected with fuel tank by oil pipe, described handle is connected with last pick body, last pick body bottom connects the outer cylinder upper end, pick body under the socket of outer cylinder lower end, described outer cylinder inside is with the flow tube, and flow tube periphery is provided with the high pressure oilhole, flow tube inside is with piston, piston top is with hydraulicchange-over valve, described hydraulicchange-over valve bottom and the sealing of flow tube, hydraulicchange-over valve top and the sealing of last pick body.
The beneficial effect of hydraulic breakup pick described in the utility model is: the configuration design of hydraulicchange-over valve becomes cylindrical, the high pressure oilhole is evenly distribution (14 hole) on circumference, the internal high pressure oil groove is designed to annular (communicating with 14 holes), the valve interior surface that cooperates with reversing valve core is processed eight road oil grooves, is beneficial to the formation oil film and plays lubrication; The fit clearance of valve body lower end and spool lower end reduces, by this design, and the one, simplified technology, improved the machining accuracy of product, reduced cost; The 2nd, improved the stability of reversal valve work, fault rate is low; The 3rd, not only improved the frequency of impact of Hydraulic pick, and the bounce to the people reduces greatly also when fragmentation, has improved broken effect simultaneously; Cylinder barrel and flow tube have been become static seal by movable sealing, cooperated compactness between the two, enhanced product performance, realized that broken effect is constant through repeatedly dismounting.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of hydraulic breakup pick described in the utility model.
Among the figure:
1, handle; 2, go up the pick body; 3, valve plate; 4, hydraulicchange-over valve; 5, piston; 6, high pressure oilhole; 7, flow tube; 8, outer cylinder; 9, following pick body; 10, flexible pipe tail pigtail.
The specific embodiment
As shown in Figure 1, the described hydraulic breakup pick of the utility model embodiment, comprise handle 1, last pick body 2, outer cylinder 8 and following pick body 9, last pick body 2 inside are provided with valve plate 3, the last pick body 2 sides flexible pipe tail pigtail 10 that spins, flexible pipe tail pigtail 10 is connected with fuel tank by oil pipe, described pick body 2 upper ends of going up connect handle 1, last pick body 2 lower ends connect outer cylinder 8 upper ends, pick body 9 under the outer cylinder 8 lower end sockets, described outer cylinder 8 inside are with flow tube 7, flow tube 7 peripheries are provided with high pressure oilhole 6, and flow tube 7 inside are with piston 5, and piston 5 top peripheries are with hydraulicchange-over valve 4, described hydraulicchange-over valve 4 bottoms and 7 sealings of flow tube, hydraulicchange-over valve 4 tops and 2 sealings of last pick body.
The described hydraulic breakup pick of the utility model embodiment, piston 5 processes of moving upward are: hydraulic oil enters pick body 2 through flexible pipe tail pigtail 10, switch valve is opened the back and is flow to valve plate 3 by the oilhole in the last pick body 2, at this moment hydraulicchange-over valve 4 around be full of hydraulic oil, hydraulic oil enters flow tube 7 through reversal valve, the spool of hydraulicchange-over valve 4 is upwards promoted by four up thimbles, hydraulicchange-over valve 4 is closed, cause hydraulic oil can't act on the upper end anchor ring of piston 5, but the lower end anchor ring of piston 5 is hydraulic oil abrim still, and the lower end anchor ring of piston 5 is subjected to the hydraulic oil effect to cause piston 5 to move upward; Piston 5 moves downward process: piston 5 continues to move upward, when the belt oil groove of piston 5 communicates with first oil groove of flow tube 7 upper ends, the lower end of up thimble communicates with high pressure oilhole 6, at this time the pressure of hydraulic oil raises gradually, accumulator nitrogen leather cup is compressed simultaneously, and energy stores.The spool of hydraulicchange-over valve 4 is promoted downwards by two descending thimbles when hydraulic oil rises to rated operating pressure, hydraulicchange-over valve 4 is opened, the upper end anchor ring of piston 5 is full of hydraulic oil, piston 5 moves downward, the accumulator energy discharges simultaneously, piston 5 quickens to move downward the strike pick rod, and a working cycles is finished.
