Description
Technical Field
The utility model relates to an auxiliary tool for installing a cylinder sleeve of an internal combustion locomotive.
Background
The diesel engine of the diesel locomotive is the heart of the diesel locomotive, and the cylinder sleeve is arranged in a cylinder body hole of the diesel locomotive body and is tightly pressed and fixed by a cylinder cover. The piston reciprocates in its inner bore and always makes high-speed sliding friction with piston ring and piston skirt. The inner surface of the cylinder sleeve is directly acted by high-temperature and high-pressure fuel gas, the outer surface of the cylinder sleeve is in contact with cooling water and corroded by the cooling water, severe thermal stress is generated under a large temperature difference, and the working condition is severe. When the engine encounters faults such as water leakage of the cylinder sleeve and the like in the daily use process of the locomotive, the cylinder sleeve assembly needs to be lifted from the engine body of the diesel engine to be replaced by a new cylinder sleeve assembly. When the cylinder sleeve is replaced, a maintainer needs to drill into the machine body to loosen the connecting rod bolt, take down the connecting rod and the piston, and reinstall the connecting rod and the piston after the cylinder sleeve is installed in place, so that the operation is complex, time-consuming and labor-consuming.
Disclosure of Invention
The utility model aims to provide an auxiliary tool for installing a cylinder sleeve of a diesel locomotive, which has good effect, stable performance, safety and reliability. The traditional complex maintenance mode is changed, and the cylinder sleeve can be installed without disassembling the connecting rod. Greatly improves the working efficiency, saves the cost and reduces the labor intensity of the operators.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an internal combustion locomotive cylinder liner installation appurtenance, includes drum, fastening screw and fastener, the drum front side is equipped with the opening, and both ends are equipped with left mounting, right mounting respectively about drum front side opening department, and the U type inslot of left mounting has fastening screw through the fix with screw, and the fastening screw right-hand member wears to establish the U type groove at right mounting, and fastening screw right-hand member spiral has the fastener.
Furthermore, a plurality of supporting nuts are uniformly arranged on the outer side of the cylinder.
Further, the thickness of the cylinder is 2mm, and the height of the cylinder is 85 mm.
The utility model has the following beneficial effects: the utility model has good effect, stable performance, safety and reliability. The traditional complex maintenance mode is changed, and the cylinder sleeve can be installed without disassembling the connecting rod. Greatly improves the working efficiency, saves the cost and reduces the labor intensity of the operators. The arrangement of the fastening screw and the fastening piece is convenient for rapidly disassembling or assembling the device.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Wherein: 1. the device comprises a cylinder, 2, a fastening screw, 3, a fastening piece, 4, an opening, 5, a left fixing piece, 6, a right fixing piece, 7, a screw, 8 and a supporting nut.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, an internal combustion locomotive cylinder sleeve installation appurtenance, including drum 1, fastening screw 2 and fastener 3, 1 front side of drum is equipped with opening 4, and both ends are equipped with left mounting 5, right mounting 6 respectively about 1 front side opening 4 department of drum, and the U type inslot of left mounting 5 is fixed with fastening screw 2 through screw 7, and the U type groove at right mounting 5 is worn to establish by fastening screw 2 right-hand member, and fastening screw 2 right-hand member spiral has fastener 3.
A plurality of supporting nuts 8 are uniformly arranged on the outer side of the cylinder 1.
The thickness of the cylinder 1 is 2mm and the height of the cylinder 1 is 85 mm.
When the cylinder sleeve is used, firstly, the fastening piece 3 is loosened to loosen the cylinder 1, the cylinder 1 is installed at the position of the piston ring, then the fastening piece 3 is screwed to enable the cylinder 1 to lock and compress the piston ring, after the piston ring is compressed, the cylinder sleeve is sleeved in from the upper part of the piston ring and is supported by the support nut 8, then the cylinder 1 is slowly pushed downwards, after the cylinder sleeve is installed in place, the fastening piece 3 is loosened from the cavity, and the cylinder 1 is taken out to complete the installation of the cylinder sleeve; the arrangement of the fastening screw rod 2 and the fastening piece 3 facilitates the quick disassembly or assembly of the device.
The present invention is not limited to the above embodiments, and any structural changes made under the teaching of the present invention shall fall within the scope of the present invention, which is similar or similar to the technical solutions of the present invention.
The techniques, shapes, and configurations not described in detail in the present invention are all known techniques.
