Description

Technical Field

[0001] The present application relates to the technical field of engine cylinder block hangers, and in particular to a V-shaped engine cylinder block hanger. Background Art

[0002] At present, when a V-shaped engine cylinder block needs to be moved during machining, a soft sling is usually used for lifting. The sling needs to be inserted into the cylinder hole on one side and out of the cylinder hole on the other side. Since the cylinder hole is small, the hand cannot reach into the cylinder hole after wearing gloves, and the sling cannot be pulled out. If the hand is not worn, it is very easy to scratch the hand. Usually, a hook is required to reach into the cylinder hole to hook out the soft sling. This method is relatively cumbersome, and the soft sling is manually fixed. It is easy for the ropes on both sides of the sling to be of different lengths, resulting in the cylinder body being unable to maintain a horizontal state during lifting. Therefore, manual intervention is required to maintain the balance and stability of the cylinder body. This method is not conducive to the rise and fall of the cylinder body on the processing fixture, and it is also easy to cause danger to the workers. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0038] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0039] The V-shaped engine cylinder block hanger of the present application is applied to a hanger of a V-shaped engine cylinder block; the present application is described in detail by taking a V-shaped 12-cylinder engine cylinder block as an example.

[0040] A V-shaped engine cylinder block hoist comprises: a first boom 1 and a second boom 2; a strip hole 3 is penetrated through the top of the first boom 1, and a stopper 4 is arranged on the top right side of the strip hole 3; the second boom 2 is arranged in the strip hole 3, and is rotatably connected to the right end of the first boom 1; the upper surface of the second boom 2 can contact the stopper 4, and a lifting ring 5 is arranged on the top of the second boom 2, and a second positioning clamping component 8 is arranged on the bottom; a first positioning clamping component 7 is arranged on the bottom of one end of the first boom 1 away from the second boom 2; the second positioning clamping component 8 cooperates with the first positioning clamping component 7 to clamp and fix the cylinder block.

[0041] In this embodiment, the sizes of the first suspension arm 1 and the second suspension arm 2 can be adapted according to the size of the cylinder block 9, so as to facilitate the lifting of different V-shaped engine cylinder blocks.

[0042] A first support arm 11 is extended downward from the left bottom of the first boom 1 ; the first support arm 11 is vertically connected to the first boom 1 , and a first positioning clamping component 7 is fixedly provided on the right side of the first support arm 11 .

[0043] Specifically, the first positioning clamping component 7 is used to cooperate with the characteristic position of the left side of the cylinder body 9 for positioning; the second positioning clamping component 8 is used to cooperate with the characteristic position of the right side of the cylinder body 9 for positioning; with the cooperation of the first positioning clamping component 7 and the second positioning clamping component 8, the cylinder body 9 is clamped by the first boom 1 and the second boom 2 to complete the lifting operation.

[0044] The first positioning and clamping component 7 includes a first clamping piece 71; the upper outer side of the first clamping piece 71 is welded and fixed to the first support arm 11; the upper inner side of the first clamping piece 71 is provided with a positioning block 72 that cooperates with the cylinder body 9 for clamping; the first clamping piece 71 is provided with positioning pins 73 at the front and rear ends of the bottom of the side away from the first support arm 11; the positioning block 72 and the two positioning pins 73 are fixed to the first clamping piece 71 by bolts.

[0045] In this embodiment, the positioning block 72 and the two positioning pins 73 are designed to be fixed by bolts, which facilitates the installation and disassembly of the positioning block 72 and the two positioning pins 73 and the timely replacement of worn parts; further, the positioning block 72 and the two positioning pins 73 respectively correspond to the left positioning shoulder 110 and the two positioning holes 130 on the left end face of the cylinder body 9, thereby realizing the left side positioning of the cylinder body 9; wherein, the upper surface of the positioning block 72 is in contact with the lower surface of the left positioning shoulder 110 of the cylinder body 9, so as to better share the gravity generated by the cylinder body 9 itself, and the upper surface of the positioning block 72 has the same curvature as the lower surface of the left positioning shoulder 110 of the cylinder body 9.

[0046] The first clamping member 71 is an inverted V-shaped structure, wherein the front arm and the rear wall of the first clamping member 71 are both provided with weight-reducing holes 74. The first clamping member 71 designed with a V-shaped structure has a higher overall strength and will not be deformed due to the gravity of the cylinder 9; in addition, the structural design of the first clamping member 71 is intended to match the characteristic position of the left side of the V-shaped engine cylinder, so that the first clamping member 71 and the characteristic position of the cylinder 9 are more consistent, and the clamping effect of the sling is better and the wear is lower due to the three-point force.

[0047] The front and rear ends of the first boom 1 are penetrated by strip-shaped weight-reducing holes 12 .

[0048] A limit block 10 is fixedly set in the middle position of the bottom of the strip hole 3, and the right side of the limit block 10 can contact and limit the left side of the second boom 2; the advantage of this design is that the limit block 10 is designed to prevent the second boom 2 from falling to the bottom of the first boom 1 under its own gravity when not in use, causing inconvenience in use; in this embodiment, the limit block 10 can ensure that when the second boom 2 is not in use, the lifting ring 5 is always located above the first boom 1, which is convenient for the hook operation.

[0049] A second arm 21 is extended upwardly from the left side of the second boom 2, and the left side of the second arm 21 can contact the limit block 10; the lifting ring 5 is fixed on the top of the second arm 21; a third arm 22 is extended downwardly from the right side of the second boom 2, and the second positioning clamping component 8 is welded and fixed on the inner surface of the third arm 22; a first axial hole 23 is provided at the connection between the second boom 2 and the third arm 22, and correspondingly, a second axial hole 13 is provided on the first boom 1, wherein the shaft 6 passes through the second axial hole 13 and the first axial hole 23 in sequence, so as to rotatably connect the first boom 1 and the second boom 2, and the part of the shaft 6 extending out of the first boom 1 is fixed by a pin 61.

[0050] The second positioning and clamping component 8 includes a second clamping piece 81, and a mounting groove is arranged on the upper outer side of the second clamping piece 81. The third arm 22 is inserted into the mounting groove and fixed in the mounting groove by welding; a supporting block 82 cooperating with the cylinder body clamping is arranged on the upper inner side of the second clamping piece 81.

[0051] The upper surface of the support block 82 contacts the lower surface of the right positioning shoulder 120 on the right end surface of the cylinder body, thereby realizing the right side positioning of the cylinder body; wherein the curvature of the upper surface of the support block 82 is the same as the curvature of the lower surface of the right positioning shoulder 120 .

[0052] A handle 100 is welded and fixed to the right side of the third arm 22 .

[0053] In this embodiment, the position where the first boom 1 and the second boom 2 are axially connected is located at the connection between the second boom 2 and the third arm 22; the advantage of this design is that, with the axis as the fulcrum, the first boom 1 and the second boom 2 are driven to rise or fall through the lifting ring 5, and under the action of the fulcrum, the distance between the first arm 11 and the third arm 22 is adjusted, thereby completing the tightening or loosening operation of the cylinder body 9.

[0054] When in use, the second boom 2 is in contact with the limit block 10 when it is in the lowest position; the distance between the first arm 11 and the third arm 22 is the largest. At this time, the sling is in an open state. When the sling is lifting the cylinder body, the overhead crane is used to slowly lift the sling body through the lifting ring 5, and with the assistance of the control handle 100, the first positioning clamping component 7 and the second positioning clamping component 8 are respectively aligned with the characteristic positions of the left and right end surfaces of the cylinder body 9, and then the lifting ring 5 is continued to be lifted, and the second boom 2 moves upward. When the second boom 2 is in contact with the stopper 4, the sling is in a fully closed and clamped state, and the rising overhead crane lifts the cylinder body 9 smoothly.

[0055] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.
