Description

Technical Field

[0001] The utility model relates to a hoisting device, in particular to a hoisting device capable of hoisting a diesel engine transmission gear to a gearbox, belonging to the technical field of lifting equipment. Background Art

[0002] Gear transmission is one of the most widely used transmission methods in mechanical transmission. In order to change the transmission distance, transmission direction and transmission ratio, it is necessary to add single (multiple) intermediate gears or single (multiple) double gears between the driving gear and the driven gear. At present, the normal operation of most components or equipment such as the intake camshaft, exhaust camshaft, lubricating oil pump and cooling water pump of marine diesel engines is realized by the crankshaft transmission parts through gear meshing transmission. In its gearbox, it is necessary to add intermediate gears or double gears to meet the requirements of different transmission distances and different transmission ratios. Since the intermediate gears and double gears are large in volume and heavy in weight, in order to ensure the installation accuracy of the gears, they are generally hoisted and installed by a crane. The existing gear hoisting device has a complex structure, poor stability and cumbersome operation, often unable to ensure the installation accuracy of the gears, and there are also certain safety hazards. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hoisting device for diesel engine transmission gears with a simple structure, low cost, time-saving and labor-saving operation, and can effectively ensure the installation accuracy of the gears.

[0004] The utility model is realized through the following technical solutions:

[0005] A hoisting device for diesel engine transmission gears includes a suspension rod, a gear mounting plate and two spacing blocks; one end of the suspension rod is fixedly connected to the middle of the gear mounting plate, a suspension plate is vertically fixed on the upper side of one end of the suspension rod, and several lifting holes are arranged at intervals at one end of the suspension plate; the two spacing blocks are respectively fixed at both ends of the gear mounting plate, and both radial ends of the gear hub are respectively abutted against the corresponding spacing blocks, and one ends of several fasteners respectively pass through the gear mounting plate and the spacing blocks and are screwed on the gear hub.

[0006] The purpose of the utility model can also be further realized by the following technical measures.

[0007] In the aforementioned hoisting device for diesel engine transmission gears, the gear mounting plate has a kidney-shaped structure with both ends being arc-shaped, several transverse kidney-shaped holes are symmetrically arranged at both ends of the gear mounting plate, and the middle transverse kidney-shaped holes respectively correspond to the positions of the connection holes at both radial ends of the gear hub.

[0008] In the aforementioned hoisting device for diesel engine transmission gears, the spacing block is arc-shaped, and several mounting holes corresponding to the positions of the transverse kidney-shaped holes are arranged on the spacing block.

[0009] The aforesaid diesel engine drive gear hoisting device, wherein the boom is made of a steel pipe, and a handle is provided on the lower side of the other end of the boom.

[0010] The utility model has the advantages of simple structure, low cost, good stability, safety and reliability. The gear to be installed is fixed on the gear mounting plate and hoisted to the gearbox on the machine frame for installation through the hanging plate. During the hoisting process, the whole device can be kept horizontally balanced by the handle on the lower side of the boom, and it can be pushed forward while hoisting until the gear is accurately pushed in place. This not only saves time and effort in operation and has high work efficiency, but also has accurate gear positioning and high positioning accuracy, which can effectively ensure the gear installation accuracy. The distance between the two spacing blocks can be adjusted according to the spacing of the connecting holes on the hubs of gears of different specifications, so that gears of various specifications can be hoisted, and the applicable range is wide.

[0011] The advantages and features of the utility model will be illustrated and explained by the following non-restrictive description of preferred embodiments, which are given only as examples with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following further illustrates the utility model with reference to the drawings and embodiments.

[0016] As Figure 1 , Figure 2 and Figure 3As shown in the figure, the utility model includes a suspension rod 1, a gear mounting plate 2 and two spacing blocks 3. The suspension rod 1 is made of a steel pipe. The right end of the suspension rod 1 is welded to the middle of the gear mounting plate 2. A suspension plate 4 is vertically provided on the upper side of the right end of the suspension rod 1. The two ends of the suspension plate 4 are respectively welded to the gear mounting plate 2 and the suspension rod 1. Two lifting holes 41 are spaced at the left end of the suspension plate 4. A handle 5 is welded to the lower side of the left end of the suspension rod 1. The two spacing blocks 3 are respectively fixed to the two ends of the gear mounting plate 2 by bolts. The two radial ends of the hub of the gear 6 respectively abut against the corresponding spacing blocks 3. One ends of two connecting bolts 7 respectively pass through the gear mounting plate 2 and the spacing blocks 3 and are screwed onto the hub of the gear 6, thereby fixedly connecting the gear 6 and the gear mounting plate 2. The gear mounting plate 2 is a waist-shaped structure with arc-shaped ends. Six transverse waist-shaped holes 21 are symmetrically provided at its two ends. The two middle transverse waist-shaped holes 21 respectively correspond to the positions of the connecting holes at the two radial ends of the hub of the gear 6. The spacing block 3 is arc-shaped. Three mounting holes 31 corresponding to the positions of the transverse waist-shaped holes 21 are provided on the spacing block 3.

[0017] Taking the installation of the intermediate gear at the flywheel end of a 32 / 40 type diesel engine as an example, according to the distance between the connecting holes at the two radial ends of the hub of the intermediate gear, adjust the distance between the two spacing blocks 3 along the transverse waist-shaped holes 21 until the middle mounting hole 31 on the spacing block 3 corresponds to the position of the connecting hole on the hub of the intermediate gear, and fixedly connect the two with the connecting bolt 7. Then connect the cross pin of the lifting shackle 8 with the left lifting hole 41 of the suspension plate 4. The sling 9 is sleeved on the body of the lifting shackle 8. Use a crane to lift the utility model together with the intermediate gear. At the same time, pull the handle 5 downward by hand to keep the suspension rod 1 horizontal. Lift the intermediate gear into the gearbox at the flywheel end of the diesel engine, so that the installation alignment marks on the teeth of the intermediate gear are respectively aligned with the installation marks on the fuel camshaft assembly gear and the intake and exhaust valve camshaft assembly gear in the gearbox. Push the present invention and the intermediate gear horizontally forward with the crane to make the intermediate gear fully mesh with the fuel camshaft assembly gear and the intake and exhaust valve camshaft assembly gear, and align the meshing marks. Fasten the intermediate gear to the frame with fasteners, and the installation is completed. In the same way, the double gear can be lifted into the gearbox at the flywheel end of the diesel engine by using the right lifting hole 41 of the suspension plate 4, and it can be respectively meshed and installed with the crankshaft main gear and the intermediate gear.
