Abstract

The utility model discloses an engine water jacket detaching tool which aims to overcome the defects of the prior art that before an engine water jacket is detached, a cylinder cover is detached firstly; before the engine water jacket is installed, a cylinder gasket needs to be replaced, thereby causing waste; the detachment of the cylinder cover also wastes manpower and time; and simultaneously,the detachment of the water jacket is difficult; a bracket which can be vertically arranged on the cylinder cover and surround the water jacket is sleeved outside a vertical screw which can be screwedon the inner hole of the water jacket; and a nut which can be supported on the bracket and pull out the water jacket with the reaction of the bracket. With the tool, the water jacket can be directlypulled out by the screw which can be directly screwed on the inner hole of the water jacket and the nut screwed on the screwed through the bracket, without detaching the cylinder cover, wasting the cylinder gasket or consuming sealant, thereby reducing operation steps, and saving manpower and time; and simultaneously, the detached water jacket can be taken out integrally without being crushed. Astested, the efficiency in detaching and replacing the water jacket is improved by more than 90 percent.

Description

The extracting tool of engine water jacket

Technical field

The utility model belongs to instrument, specifically a kind of instrument of engine water jacket for convenience detach.

Background technology

The engine that uses on the crane because service life is long, often because of the water jacket corrosion seriously drainage takes place, just needs the dismounting water jacket to change in case leak.To the dismounting of water jacket, need at first the cylinder head of engine to be pulled down at present, water jacket could be cast from the installation site then.When refilling new water jacket after with the dismounting of old water jacket, the former of cylinder head just can not have been used with head gasket, must more renew pad, spreads fluid sealant again and seals, and so not only wasted head gasket, but also wasted the manpower and the time of tearing cylinder head open; Simultaneously, because water jacket wall is thinner, under the corrosion serious situation, be easy to fragmentation during the water jacket dismounting, the water jacket after the dismounting fragmentation is difficulty very.

The utility model content

Technical problem to be solved in the utility model is, when overcoming prior art dismounting engine water jacket, to dismantle cylinder head earlier, the head gasket that will renew when again cylinder head being installed causes waste, the dismounting cylinder head is waste of manpower and time also, the easy fragmentation of the water jacket that is disassembled simultaneously causes the shortcoming of dismounting difficulty, and a kind of extracting tool of engine water jacket is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: in the setting screw rod outside that can twist on the water jacket endoporus, be with to erect and be placed on the cylinder head, water jacket is enclosed within it bearing, upper end at screw rod, be screwed with and be supported on the bearing, the nut of water jacket being extracted by the reaction force of bearing.

The utility model also has following technical characterictic:

Described bearing is a cylindrical seat, and at the flat shim that is placed with suitable for reading of cylindrical seat, the center of flat shim is provided with the pad hole that screw rod is passed;

Described bearing is for falling cup-shaped seat, and the center is provided with the hole that screw rod is passed at the bottom of cup;

Described screw rod is combined by the epimere and the hypomere of different thicknesses and pitch.

During use, at first use screw tap tapping internal thread on the water jacket endoporus, will be screwed on the internal thread hole with the screw rod setting that water jacket hole internal thread adapts again, but the bearing that is trapped among water jacket periphery holding nut is placed on the cylinder head, fastening nut can be extracted water jacket by the reacting force of supporting of bearing.

Advantage of the present utility model and good effect are, because above-mentioned instrument dismounting water jacket, be with the setting screw rod and the nut that is screwed on the screw rod that can directly be screwed on the water jacket endoporus, rely on the reaction force of bearing that water jacket is directly extracted, not needing to dismantle cylinder head is detachable water jacket, does not waste head gasket, does not also just consume fluid sealant, thereby reduced operating procedure, saved manpower and time; The water jacket that is disassembled simultaneously can whole the proposition and can be broken, and dismounting has also been guaranteed the cylinder body safety of engine easily.Through test, the efficient of dismounting and change water jacket has improved more than 90%.This instrument dismounting is simple, and it is convenient to change water jacket, can be used for the dismounting of crane engine water jacket other cover base parts in addition.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the structural representation of the another kind of embodiment of the utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, use on the engine jacket 6 of screw tap tapping internal thread within it on the hole 6.1, to twist on the internal thread of endoporus 6.1 with the setting screw rod 1 that above-mentioned internal thread adapts, the top of exposing cylinder head 5 of screw rod 1, be with to erect and be placed on the cylinder head 5, water jacket 6 is enclosed within it bearing, in the upper end of screw rod 1, be screwed with and be supported on the bearing, the nut of water jacket 6 being extracted by the reaction force of bearing 2.

Described bearing is a cylindrical seat 4, and at the flat shim 3 that is placed with suitable for reading of cylindrical seat 4, the center of flat shim 3 is provided with the pad hole 3.1 that screw rod 1 is passed.To be positioned at sides below the cylindrical seat 4, projection 5.1 on engine cylinder cap 5 in order walking around, to be positioned at the position leaving certain gaps uncovered by the economic plan 4.1 of projection 5.1 in the bottom of cylindrical seat 4.

Among Fig. 2, described bearing also can be cup-shaped seat 7, during use, cup-shaped seat 7 is tipped upside down on the engine cylinder cap 5, the center is provided with and the above-mentioned hole 7.1 that screw rod 1 is passed at the bottom of its glass, is positioned at the position leaving certain gaps uncovered by the economic plan 7.2 of projection 5.1 too in the bottom of cup-shaped seat 7.

The utility model can be used for the multiple dismounting that is similar to the engine water jacket parts, in order to adapt to the needs of different big small water sleeve 6 endoporus of dismounting, described screw rod 1 can be thickness and a pitch (referring to Fig. 1) unanimous between the higher and lower levels, the epimere 1.1 and the hypomere 1.2 that also can be divided into different thicknesses and pitch, epimere 1.1 is fixing a kind of thickness and pitch, hypomere 1.2 is according to the endoporus setting of different water jackets 6, and then (referring to Fig. 2) combined in connection.
