Abstract
The utility model discloses a spiral embedded oil cylinder guide sleeve applicable to a rotary drilling rig. The spiral embedded oil cylinder guide sleeve is characterized in the guide sleeve is a split type guide sleeve and consists of an embedded sleeve and a spiral cover, the embedded sleeve is assembled with a sealing element, and one end of the embedded sleeve is provided with a concave platform; the spiral cover is sleeved on the outer circle surface of the concave platform of the embedded sleeve and is connected with the thread of the inner circle surface of an oil cylinder barrel, and shoulders used for axially positioning are arranged between the embedded sleeve and the oil cylinder barrel, between the spiral cover and the oil cylinder barrel, and between the spiral cover and the embedded sleeve. According the spiral embedded oil cylinder guide sleeve, the guide sleeve is designed to be in a split type, so that the damaged on the sealing element can be effectively reduced when the guide sleeve is assembled, and the appearance size of the cylinder barrel on the guide sleeve can be reduced, so that the spiral embedded oil cylinder guide sleeve is particularly applicable to a mast cylinder and a boom cylinder on the rotary drilling rig of which the installation spaces are limited.
Description
Technical field
The utility model relates to rotary drilling rig hydraulic system, particularly rotary drilling rig guide sleeve for hydraulic oil cylinder.
Background technique
Rotary drilling rig is a kind of efficient pore-forming equipment of widely used heavy caliber in foundation construction of fully hydraulic driven, because its power is large, power is strong, easy to use, pore-forming is quick, is widely used in the pile foundation construction of engineering, building.Rotary drilling rig, in construction, need to drive by hydraulic jack and realize vertical mast, movable mast, vertical adjustment, to the action such as hole and pressurization, and these actions are very important links in construction.Therefore, reasonably oil cylinder design, can improve oil cylinder working life, improves the performance of rotary drilling rig.The guide sleeve for hydraulic oil cylinder that uses on existing rotary drilling rig is common is two kinds, is integrated type, and one is spiral guide sleeve (as shown in Figure 1), and one is flange-type guide sleeve (as shown in Figure 2).Threaded guide sleeve is in when assembling, and the Sealing on guide sleeve 6 is followed guide sleeve and rotated together, is high-voltage oil cylinder due to what use on rotary drilling rig, withstand voltage for guaranteeing, screwing in distance need be longer, easily like this causes disengagement of seal member seal groove, and damages Sealing; Flange-type guide sleeve is bolton, by bolt, guide sleeve is assemblied on cylinder barrel, Sealing embeds along axis together with guide sleeve, but this form need by local the excircle dimension of cylinder barrel increasing could be on cylinder barrel drilling and tapping for bolton, this structure is restricted installing.
Model utility content
It is a kind of for the compact structure on rotary drilling rig that the utility model is to provide, and can realize to Sealing good protection guide sleeve for hydraulic oil cylinder, to solve the shortcoming and defect in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of embedded oil cylinder guide sleeve of spiral that is applicable to rotary drilling rig, it is characterized in that, described guide sleeve is split type guide sleeve, formed by embedding cover and screw lid assembling, its embedding puts and is equipped with Sealing, the one end that embeds cover is provided with concave station, described screw lid is socketed in and embeds the periphery of cover concave station and be threaded with the inner headed face of cylinder tube, between described embedding cover and cylinder tube, between screw lid and cylinder tube, and between screw lid and embedding cover, be provided with the shoulder matching in order to axially locating.
Beneficial effect: the utility model is by being designed to guide sleeve split formula, damage to Sealing can effectively reduce guide sleeve assembling time, and reduce the boundary dimension of guide sleeve place cylinder barrel, be specially adapted to the restricted mast oil cylinder of installing space and boom cylinder on rotary drilling rig.
Accompanying drawing explanation
Fig. 1 is the spiral guide sleeve structure figure that original rotary drilling rig hydraulic jack uses;
Fig. 2 is the flange-type guide sleeve structure figure that original rotary drilling rig hydraulic jack uses;
Fig. 3 is structural representation of the present utility model.
In figure: 1-screw lid 2-embedding cover, 3-Sealing, 4-cylinder tube, 5-piston rod
6-guide sleeve
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail as follows:
As shown in Figure 3, a kind of embedded oil cylinder guide sleeve of spiral that is applicable to rotary drilling rig, its guide sleeve is split type guide sleeve, formed by embedding cover 2 and screw lid 1 assembling, its embedding puts and is equipped with Sealing 3, the one end that embeds cover is provided with concave station, described screw lid is socketed in and embeds the periphery of cover concave station and be threaded with the inner headed face of cylinder tube 4, between described embedding cover and cylinder tube, between screw lid and cylinder tube, and between screw lid and embedding cover, be provided with the shoulder matching in order to axially locating.
When the assembling of this device, first screw lid is inserted in to piston rod 5, after Sealing is embedded on the seal groove that embeds Analysis of Nested Design, and embeddings is inserted in to piston rod, then fit in cylinder tube being inserted in the piston rod that screw lid and embedding overlap.Guide sleeve being packed in cylinder tube process, first embedding cover is slowly beaten to embedding cylinder tube, embed between cover and cylinder barrel and design shoulder in order to axially locating.When embedding cover and cylinder tube after shoulder place is withstood, then screw lid is screwed in cylinder tube, be now seated owing to embedding cover, can not follow screw lid to rotate together, and Sealing be all arranged on embed put, therefore, Sealing is not easy to run out of seal groove, has avoided damage.Between screw lid and cylinder tube and between screw lid and embedding cover, be provided with shoulder for axially locating, screw lid screwed in to cylinder tube until assembled after shoulder place dieback.This guide sleeve device, has guaranteed that in assembly process, Sealing only embeds along oil cylinder axis, without spin, can effectively reduce the damage of Sealing in assembly process.
