Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The present invention will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present invention.
Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of an engine cylinder cover lifting tool according to an embodiment of the present invention; FIG. 2 is a front view of the engine head lifting tool shown in FIG. 1 in an expanded state; fig. 3 is a front view of the engine head lifting tool shown in fig. 1 in a clamped state.
The invention provides an engine cylinder cover hoisting tool which comprises a connecting rod assembly, a first lifting hook 1 and a second lifting hook 2, wherein the input end of the connecting rod assembly is used for being connected with power equipment for hoisting a cylinder cover, and the first lifting hook 1 and the second lifting hook 2 are fixed at the output end of the connecting rod assembly and are used for moving towards and away from each other under the action of the connecting rod assembly; the first lifting hook 1 and the second lifting hook 2 are respectively embedded in an air inlet and two air outlets on the left side and the right side of the cylinder cover, and the air inlet and the air outlet on the cylinder cover are utilized to realize quick and stable hanging.
The corresponding modes of the first lifting hook 1 and the second lifting hook 2, the air inlet hole and the air outlet hole are not limited to the above situations, and can be divided into two situations: first lifting hook 1 blocks simultaneously and inlays in two inlet port and the second lifting hook 2 block in one exhaust hole of cylinder cap exhaust side of cylinder cap air inlet side, and second lifting hook 1 blocks in one inlet port and the second lifting hook 2 block simultaneously in two exhaust holes of cylinder cap exhaust side of cylinder cap air inlet side. It should be noted that the engine cylinder cover lifting tool has two different setting modes, and does not mean that the engine cylinder cover lifting tool can be reversely installed only by changing the positions of the first lifting hook 1 and the second lifting hook 2 when in use. Because there may be differences between the positions, sizes and heights of the air inlet and the air outlet on the engine cylinder cover, the position of the lifting hook is not necessarily ensured to be accurately matched with the cylinder cover when the engine cylinder cover lifting tool is used, so that the lifting is realized.
Compared with the prior art that the hanging of the cylinder cover is realized through a plurality of threaded holes, the tool utilizes the existing structure of the cylinder cover, namely the air inlet and the air outlet, the position of the structure on the cylinder cover is fixed, and the accurate hanging of any cylinder of the same type can be ensured by adopting a tool matched with the structure; meanwhile, the tool is simple in structure and convenient to operate, and only the first lifting hook 1 and the second lifting hook 2 are required to be respectively clamped and embedded in the air inlet hole and the air outlet hole. In order to avoid possible tipping when the lifting hooks are clamped with the two points of the cylinder cover, the number of contact points of the first lifting hooks 1 and the second lifting hooks 2 with the air inlet holes and the air outlet holes is three, so that three-point positioning clamping is realized.
The engine cylinder cover lifting tool provided by the invention is further described below with reference to the accompanying drawings and the implementation mode.
In order to facilitate the connection between the power equipment and the engine cylinder cover lifting tool, the engine cylinder cover lifting tool also comprises a lifting ring 3 arranged between the power equipment and the connecting rod assembly; the lifting ring 3 can be connected with the existing power equipment for lifting the engine cylinder cover, and is simple and quick to operate. On this basis, the connecting rod assembly comprises two first linkage shafts 41 with first ends connected to the bottom of the lifting ring 3 in a rotating way, and two second linkage shafts 42 with first ends connected to the second ends of the two first linkage shafts 41 in a rotating way respectively, wherein the two second linkage shafts 42 are connected in a rotating way at the crossing points after crossing; wherein the first hooks 1 and the second hooks 2 are fixed to the second ends of the two second coupling shafts 42, respectively.
When the engine cylinder cover is hung, the power equipment is not connected or the connecting rod assembly is not hung in the air under the action of the power equipment and the hanging ring 3, the tail end of the second linkage shaft 42, namely the second end connected with the first hanging hook 1 and the second hanging hook 2, is in a free state, in other words, when the input end of the connecting rod assembly does not input motion through the power equipment, the output end of the connecting rod assembly can be driven to move under the artificial action, for example, the second linkage shaft 42 is lifted relative to the first linkage shaft 41, so that the first hanging hook 1 and the second hanging hook 2 positioned at the tail end of the second linkage shaft 42 can move away from each other to enlarge the distance between the first hanging hook 1 and the second hanging hook 2.
When the distance between the first lifting hook 1 and the second lifting hook 2 is enlarged to be enough to accommodate the cylinder cover, the cylinder cover can be clamped and embedded between the first lifting hook 1 and the second lifting hook 2 through the inherent air inlet hole and the inherent air outlet hole. Once the first lifting hook 1 and the second lifting hook 2 are mutually clamped and embedded with the air inlet hole and the air outlet hole of the cylinder cover, namely, the output end of the connecting rod assembly is connected with a larger load, when the power equipment suspends the cylinder cover through the suspension ring 3, the first linkage shaft 41 pulls the second linkage shaft 42 to move towards the vertical direction, so that the tail ends of the two second linkage shafts 42 are mutually close, namely, the first lifting hook 1 and the second lifting hook 2 which are positioned at the tail ends of the two second linkage shafts 42 are mutually close, and the cylinder cover is clamped to move upwards.
The length of the first linkage shaft 41 and the second linkage shaft 42 and the position of the intersection point of the two second linkage shafts 42 have an influence on the movement range between the first lifting hook 1 and the second lifting hook 2, and changing the positions of the first linkage shaft 41, the second linkage shaft 42 and the intersection point of the two second linkage shafts 42 can cause the movement range between the first lifting hook 1 and the second lifting hook, although the engine cylinder cover is different in model and structure, the movement range between the first lifting hook 1 and the second lifting hook 2 is still within a certain range, and obviously, the greater the movement range between the first lifting hook 1 and the second lifting hook 2 is, the greater the practicability is, so the size and the mutual position relation of the structures can be comprehensively considered according to the size and the structure of the engine cylinder cover in actual operation.
After the power equipment and the hanging ring 3 suspend the cylinder cover, the two second coupling shafts 42 are towed downward toward the vertical direction due to the large mass of the cylinder cover, so that the first hooks 1 and the second hooks 2 positioned at the ends of the two second coupling shafts 42 move toward each other, thereby clamping the cylinder cover. However, it is not excluded in this process that the lifting ring 3 and the two first coupling shafts 41 are already decelerated during the sudden stop of the power plant, and the engine cylinder head still moves upwards at a relatively high speed by inertia, so that the two second coupling shafts 42 tend to move horizontally, which may cause the distance between the first lifting hook 1 and the second lifting hook 2 to be enlarged, and there is a risk that the cylinder head falls off.
In view of the foregoing, the connecting rod assembly of the engine cylinder cover lifting tool provided by the present invention further includes a first rotating shaft 43 disposed at the connection between the lifting ring 3 and the two first linkage shafts 41 and used for rotating the two first linkage shafts 41 around the connection; a second rotating shaft 44 provided between any one of the first coupling shafts 41 and one of the second coupling shafts 42 on the same side; a third rotating shaft 45 arranged at the intersection of the two second coupling shafts 42 and used for rotating the two second coupling shafts 42 around the intersection, and two locking nuts 46 respectively arranged at the end of any rotating shaft away from the boss and used for adjusting the fastening degree of the rotating shafts.
It can be seen that any one of the rotating shafts adopted in the above embodiments has a boss at one end, and can stop relative to the mounting surface; the other end is provided with an external thread, a spindle which can be engaged with the lock nut 46, and a manner of setting such a spindle will be described later as an example. Of course, if a cylindrical shaft is used, external threads are required at both ends of the shaft to adjust the rotation amplitude at the shaft by at least two lock nuts 46 at both ends of the shaft, respectively.
When the engine cylinder cover lifting tool provided by the invention is used for lifting the cylinder cover, the tail ends of the two second linkage shafts 42, namely the distance between the second lifting hooks 2 and the second lifting hooks 2, are manually adjusted to be matched with the size of the cylinder cover, so that the cylinder cover is clamped and embedded between the first lifting hooks 1 and the second lifting hooks 2 through the inherent air inlet holes and the inherent air outlet holes of the cylinder cover; the current movement form of the connecting rod assembly is fixed through a first rotating shaft 43, two second rotating shafts 44, a third rotating shaft 45 and locking nuts 46 on the first rotating shaft, so that the tail ends of the two second connecting shafts 42 can not drive the first lifting hooks 1 and the second lifting hooks 2 to expand a distance, and the cylinder cover falls off.
The number of the locking nuts 46 on each rotating shaft is not limited to two, and considering the extrusion and abrasion conditions possibly caused by the weight of the cylinder cover to the internal threads of the locking nuts 46, the two locking nuts 46 are preferably distributed on the same rotating shaft, if the internal threads of one locking nut 46 slide, the cylinder cover can still be ensured not to fall off in the lifting process, and the safety of personnel is ensured.
The core thought that first lifting hook 1 and second lifting hook 2 set up lies in that two lifting hooks utilize the current structure of cylinder cap to realize three-point centre gripping on the opposite face of cylinder cap at faster speed, with the stability of guaranteeing to lift by crane in-process cylinder cap, will now be explained taking a concrete embodiment of lifting hook as an example.
The first lifting hook 1 comprises two air inlet hole locating pins 11 for clamping and embedding two air inlet holes on the air inlet side of the cylinder cover and an air inlet side bracket 12 arranged between one air inlet hole locating pin 11 and a second linkage shaft 42 on the same side; similarly, the second hook 2 includes one exhaust hole positioning pin 21 for being respectively engaged with one exhaust hole of the cylinder head exhaust side and an exhaust side bracket 22 provided between the two exhaust hole positioning pins 21 and the second coupling shaft 42 on the same side.
Obviously, the pin diameters of the above-mentioned one air intake hole positioning pin 11 and two air exhaust hole positioning pins 21 should be adapted to the sizes of the air intake holes and the air exhaust holes of the cylinder head, respectively, and since there may be a height difference between the air intake holes and the air exhaust holes of the cylinder head in the vertical direction, the height between the air intake hole positioning pins 11 and the air exhaust hole positioning pins 21 should be adjusted according to the actual situation to adapt to the structure of the cylinder head.
Whether the cylinder cover is a 4-valve cylinder cover or a 6-valve cylinder cover, the number of air inlet holes or air outlet holes on the cylinder cover is always more than the number of pin posts, that is, two air outlet hole positioning pins 21 can be arranged to be clamped in two air outlet holes farthest away from each other or can be arranged to be clamped in two adjacent air outlet holes; also, there are various options for the location of the inlet hole locating pin 11. In general, the air inlet positioning pin 11 is positioned between the two air outlet positioning pins 21, which is more helpful to maintain the balance of the cylinder cover in lifting, and meanwhile, the stress on each pin is equivalent, the service life is equivalent, so that one pin is not broken suddenly due to overlarge stress, and safety accidents are avoided.
To further improve the strength and reliability of the connecting rod assembly, the connecting rod assembly further includes reinforcing ribs 47 provided between the intake side bracket 12 and the second linking shaft 42 on the same side and between the exhaust side bracket 22 and the second linking shaft 42 on the same side, respectively. Because the exhaust side support 22 is fixed with two exhaust hole positioning pins 21, and the two exhaust hole positioning pins 21 are generally symmetrically distributed by taking the plane of the connecting rod assembly as a symmetry plane, the exhaust side support 22 can be provided with two reinforcing ribs 47; wherein, the first end of any reinforcing rib 47 is fixed with the end of the second linkage shaft 42 of the connecting rod assembly, and the second end is fixed with the exhaust side bracket 22.
On the basis of any one of the above embodiments, the connecting rod assembly further includes limiting pins 48 respectively fixed to the two second linkage shafts 42 for limiting the rotation range of the two second linkage shafts 42 around the intersection point thereof. The two limiting pins 48 are respectively arranged on the side walls of the shaft surfaces of the two second linkage shafts 42, which are close to the intersection point, and one limiting pin 48 is positioned above the intersection point, and the other limiting pin 48 is positioned below the intersection point. One of the limit pins 48 is used to limit the maximum rotational limits of the two linkage shafts and the other limit pin 48 is used to limit the minimum rotational limits of the two linkage shafts. Meanwhile, the distance between the limiting pin 48 and the intersection influences the rotation range of the two second linkage shafts 42, and the use sense of the whole engine cylinder cover hoisting tool can be adjusted by adjusting the position of the limiting pin 48, so that the hoisting speed is improved.
The specific arrangement positions of the two limit pins 48 and the respective limit effects are not limited to the above-described embodiments, as long as the range of movement between the first hook 1 and the second hook 2 can be limited to a reasonable range. Of course, other structures capable of achieving the limiting effect may be used as the limiting pin 48 according to the present invention.
The engine cylinder cover lifting tool needs to manually adjust the relative positions between the two first linkage shafts 41 and the two second linkage shafts 42 before use so as to enlarge the distance between the first lifting hook 1 and the second lifting hook 2, and for the convenience of adjustment of operators, the tool further comprises handles 5 which are respectively arranged on the two second linkage shafts 42 and used for manual holding. The number of handles 5 is generally not less than two, and at least one handle 5 is provided on each of the second coupling shafts 42. When the first hook 1 and the second hook 2 are not clamped in the air inlet hole and the air outlet hole, the output end of the connecting rod assembly can be regarded as no load, so that the positions of the first hook 1 and the second hook 2 can be easily adjusted by pulling the handle 5. The handle 5 and the second linkage shaft 42 are not absolutely fixed, but the handle 5 can be fixed on the second linkage shaft 42 in a fixed shaft rotation mode, when an operator grasps the handle 5 to lift the two second linkage shafts 42 upwards, the handle 5 can rotate around the fixed shaft at the connecting point of the handle 5 and the second linkage shaft 42, and the operator can conveniently adjust the limb actions of the operator.
The engine cylinder cover lifting tool provided by the invention is described in detail above. The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the invention can be made without departing from the principles of the invention and these modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
