DETAILED DESCRIPTION

[0031] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range protected by the utility model.

[0032] Please refer to Figures 1-11 The utility model provides a kind of technical scheme:

[0033] A sleeve hoisting installation hole positioning guide tool, including screw rod 1, guide cone 2 and locking cap 3, and, by the cooperation of screw rod 1, guide cone 2 and locking cap 3, the flange plate 51 on sleeve pipe 5 can be aligned with the installation hole of mounting base 4, the specific specification size of screw rod 1, guide cone 2 and locking cap 3 is not specifically defined here, and the appropriate specification size of screw rod 1, guide cone 2 and locking cap 3 can be selected according to the specification size of actual mounting base 4 and sleeve pipe 5 during actual operation, the structure and working principle of the three parts are described in detail below.

[0034] Said screw rod 1 is adapted to the screw hole 41 of mounting base 4, is screwed into the screw hole 41 when using screw rod 1, and the top end surface of screw rod 1 is provided with recess 11.

[0035] Said guide cone 2 top is conical, bottom end is provided with boss column 21, boss column 21 is detachably inserted and fixed in the inside of recess 11, and guide cone 2 cooperates with the flange hole 511 on the flange plate 51 of sleeve pipe 5 to realize the positioning of sleeve pipe 5;After the boss column 21 in it is inserted into the inside of recess 11, screw rod 1 and guide cone 2 are coaxially arranged.

[0036] Said locking cap 3 includes insertion rod 31 matched with recess 11 and lock cap 32 fixed at the top end of insertion rod 31.

[0037] The detachable insertion mode between boss column 21 and recess 11 is as follows.

[0038] The inner circumferential surface of the recess hole 11 is provided with a clamping groove 12; the outer circumferential surface of the boss column 21 and the outer circumferential surface of the insertion rod 31 are both provided with outward protruding protrusions 211; the protrusions 211 are detachably clamped in the clamping groove 12, and the protrusions 211 can adopt a semispherical shape.

[0039] In specific use, before hoisting the equipment, appropriate specifications of the screw rod 1, the guide cone 2 and the locking cap 3 are selected, and the screw rod 1 and the guide cone 2 are clamped and fixed together by the cooperation of the clamping groove 12 and the protrusion 211; then the bottom of the screw rod 1 is screwed into the screw hole 41 of the installation base 4, and usually 2-3 groups of combinations of the screw rod 1 and the guide cone 2 are needed before hoisting; then the equipment is hoisted, when hoisted to above the guide cone 2, the sleeve 5 is manually held and slowly lowered, the flange hole 511 of the flange plate 51 is aligned with the guide cone 2 below (for example, in the case of three groups of screw rod 1 and guide cone 2, during the process of manually holding and slowly lowering the sleeve 5, the flange hole 511 of the flange plate 51 needs to be aligned with the corresponding guide cone 2), because the top end of the guide cone 2 is conical, it can be relatively easily inserted into the corresponding flange hole 511, then the equipment is slowly lowered onto the installation base 4, due to the positioning effect of the guide cone 2, the screw hole 41 of the installation base 4 is accurately aligned with the flange hole 511 of the flange plate 51, then the guide cone 2 is removed, and the locking cap 3 is screwed onto the screw rod 1.

[0040] The detachable clamping mode of the protrusion 211 and the clamping groove 12 has the following two implementation modes.

[0041] Implementation mode one: the recess hole 11 is a circular hole coaxially arranged with the screw rod 1, and the boss column 21 is a circular column; the clamping groove 12 is an L-shaped groove, the top end of the vertical groove section 121 of the L-shaped groove extends to the top end surface of the screw rod 1; the protrusion 211 can slide from the top end to the bottom end of the vertical groove section 121, and be rotated to slide into the horizontal groove section 122 of the L-shaped groove; the clamping groove 12 and the protrusion 211 can both be provided with two.

[0042] The specific working principle of the implementation mode one is that: the mode of clamping and fixing the screw rod 1 and the guide cone 2 together is that: the screw rod 1 is vertically placed with the recess hole 11 upward, then the guide cone 2 is moved to vertically move the boss column 21 at the bottom of the guide cone 2 together, and in the process of moving downward, the protrusion 211 is aligned with the vertical groove section 121 of the L-shaped groove, after the protrusion 211 slides into the vertical groove section 121, the guide cone 2 is continuously moved downward, after the protrusion 211 moves to the bottom end of the vertical groove section 121, the guide cone 2 is rotated, so that the protrusion 211 is rotated and slid into the inside of the horizontal groove section 122, the clamping and locking of the guide cone 2 and the screw rod 1 are completed; when the guide cone 2 is to be removed, the guide cone 2 is directly rotated in the reverse direction, so that the protrusion 211 is rotated from the horizontal groove section 122 to the bottom end position of the vertical groove section 121, then the guide cone 2 is directly pulled upward, so that the guide cone 2 and the screw rod 1 are separated.

[0043] The inner part of the boss column 21 and the inner part of the inserting rod 31 are formed with a hollow cavity 212, and a through hole 213 is formed on the outer circumferential surface of the boss column 21 and communicates with the hollow cavity 212; the inner part of the hollow cavity 212 is provided with an elastic member 214, the protrusion 211 is supported by the elastic member 214 and passes through the through hole 213 from the inner part of the hollow cavity 212 and protrudes from the outer circumferential surface of the boss column 21; the protrusion 211 in the embodiment has two, and the corresponding clamping groove 12 also has two (or the clamping groove 12 is annular), and the elastic member 214 is a V-shaped spring piece.

[0044] The specific working principle of the embodiment two is that the mode of clamping and fixing the screw rod 1 and the guide cone 2 together is that the screw rod 1 is vertically placed and the concave hole 11 faces upward, then the guide cone 2 is moved to drive the bottom boss column 21 to vertically move downward, and the boss column 21 is directly inserted into the inner part of the concave hole 11; in the process, due to the existence of the elastic member 214, the protrusion 211 is extruded by the inner circumferential surface of the concave hole 11, so that the elastic member 214 is elastically deformed, the protrusion 211 is completely retracted into the inner part of the through hole 213, and when the protrusion 211 moves to one side of the clamping groove 12, the protrusion 211 is popped out from the inner part of the through hole 213 and clamped into the inner part of the clamping groove 12 under the elastic force of the elastic member 214; when the guide cone 2 is taken off, the guide cone 2 is directly pulled upward to be pulled out from the screw rod 1.

[0045] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
