Referring to fig. 1 to 3, fig. 1 illustrates a schematic structural diagram of a switch machine lifting device 100 according to an embodiment of the present invention, fig. 2 illustrates a schematic structural diagram of a switch machine lifting device 100 when preparing to dock with one of corners 210 of a switch machine 200 according to an embodiment of the present invention, and fig. 3 illustrates a schematic structural diagram of a switch machine lifting device 100 when preparing to dock with the switch machine 200 according to an embodiment of the present invention. An embodiment of the utility model provides a pair of goat lifts shipping unit 100, goat lifts shipping unit 100 includes: a lifting body 110, an insert 120 and two stoppers 130. The side of the lifting body 110 is fixedly coupled to the insert 120. The insert 120 is adapted to be inserted into a mounting hole 221 on a foot plate 220 of the switch machine 200. One end of each of the two limiting members 130 is fixedly connected to the same end of the lifting body 110, an included angle is formed between the two limiting members 130, and the two limiting members 130 are respectively configured to abut against two side surfaces of the corner portion 210 of the switch machine 200.

It should be noted that, an included angle formed between the two limiting members 130 is, for example, 80 °, 85 °, 90 °, 95 °, or 100 °, and the like, and is not limited herein, a specific size of the included angle between the two limiting members 130 is determined according to two side surfaces of the corner portion 210 of the switch machine 200, and when the included angle between the two side surfaces of the corner portion 210 of the switch machine 200 is large, the two limiting members 130 simultaneously collide with the two side surfaces of the corner portion 210 of the switch machine 200, and the included angle between the two limiting members 130 is correspondingly large; conversely, when the angle between the two side surfaces of the corner portion 210 of the switch machine 200 is smaller, the angle between the two limiting members 130 is correspondingly smaller.

It should be noted that when the insert 120 of the switch machine lifting device 100 is inserted into the mounting hole 221 of the foot plate 220 of the switch machine 200, and the two limit pieces 130 of the switch machine lifting device 100 are respectively abutted against the two side surfaces of the corner portion 210 of the switch machine 200, so that the maintenance person holds the lifting body 110, and the end of the lifting body 110 exerts an upward acting force on the switch machine 200 by the lever principle, so as to easily lift the corner portion 210 of the switch machine 200, so that the carrying operation is convenient, and the maintenance person does not need to directly contact the bottom of the switch machine 200 with hands.

It should be noted that, a specific example of the lifting body 110 is a rod body as illustrated in fig. 1 to 6, and of course, the lifting body 110 may be a plate body or other shape structure, for example, and is not limited herein.

When the switch machine lifting device 100 is used to lift the switch machine 200, for example, two to four service personnel respectively hold one switch machine lifting device 100, and two to four switch machine lifting devices 100 are correspondingly connected to two to four corners 210 of the switch machine 200 one by one, that is, the plug 120 of the switch machine lifting device 100 is inserted into the mounting hole 221 of the foot plate 220 of the switch machine 200, and simultaneously, the two limit pieces 130 of the switch machine lifting device 100 are respectively abutted against two side surfaces of the corner 210 of the switch machine 200, so that the two to four service personnel all hold the lifting body 110, and the end of the lifting body 110 exerts an upward acting force on the switch machine 200 by the lever principle, so as to easily lift the switch machine 200, the carrying operation is convenient, and in addition, the service personnel are far away from the switch machine 200 due to the lifting body 110, so that the service personnel can be prevented from being injured during the carrying of the switch machine 200, the safety is high.

Specifically, when only two service personnel lift the rut machine 200, the two service personnel respectively act on the two opposite corner portions 210 of the switch machine 200 by using the two switch machine lifting devices 100 to lift the rut machine 200; when three maintenance personnel lift and operate the rut machine 200, the three maintenance personnel respectively act on three corner parts 210 of the switch machine 200 by adopting three switch machine lifting devices 100 in total to lift and operate the rut machine 200; when four maintenance workers lift the rut machine 200, the four maintenance workers use the four switch lifting devices 100 in total to act on the four corner portions 210 of the switch machine 200, respectively, to lift the rut machine 200.

Referring to fig. 1 to 3, the limiting member 130 is a limiting plate, and a plate surface of the limiting plate is configured to abut against a side surface of the corner 210 of the switch machine 200. Thus, when the plate surface of the limit plate is in contact with the side surface of the corner portion 210 of the switch machine 200, a good fixing effect between the limit plate and the switch machine 200 can be achieved, and the phenomenon of slipping between the limit member 130 and the side surface of the corner portion 210 of the switch machine 200 in the lifting process can be avoided. It can be understood that the limiting member 130 is not limited to a limiting plate, and may also be a limiting column, a cylindrical surface of the limiting column contacting with the side surface of the corner portion 210 of the switch machine 200 is an anti-slip surface, and when the cylindrical surface of the limiting column contacts with the side surface of the corner portion 210 of the switch machine 200, the phenomenon of slipping between the limiting member 130 and the side surface of the corner portion 210 of the switch machine 200 during the lifting and transporting process can be avoided, and the bearing effect is good. Of course, the limiting member 130 may be a limiting structure with other shapes as long as it can collide with the side surface of the corner portion 210 of the switch machine 200 to form a force-bearing point, and the specific shape structure of the limiting member 130 is not limited herein.

Referring to fig. 1 to 3 again, in one embodiment, the insert 120 is a pin or a bolt, and the insert 120 is used for clearance fit with the mounting hole 221. Thus, the insert 120 can be easily inserted into the mounting hole 221, and the insert 120 can interfere with the wall of the mounting hole 221 as a force bearing point during the transportation process.

Please refer to any one of fig. 4 to 6, fig. 4 illustrates a schematic structural diagram of a switch machine lifting device 100 according to another embodiment of the present invention, fig. 5 illustrates a schematic structural diagram of a switch machine lifting device 100 according to another embodiment of the present invention, and fig. 6 illustrates a schematic structural diagram of a switch machine lifting device 100 according to yet another embodiment of the present invention. In one embodiment, the end of the lifting body 110 remote from the insert 120 is provided with a handle 140. In this way, the maintenance personnel can conveniently lift and carry the main body 110 by holding the handle 140 with hands, and the operation is convenient. Particularly, the handle 140 can be provided with an anti-slip layer, so that the phenomenon of slipping in the carrying process is avoided, and the carrying effect is good. In addition, a soft layer or an elastic layer can be sleeved on the handle 140, so that the comfort of holding the handle 140 is improved.

Referring to fig. 4, the handle 140 is optionally embodied as a handle disposed on a side of the lifting body 110 away from the insert 120. That is, the two ends of the handle 140 are respectively connected to the side of the lifting body 110 away from the plug 120, so that the handle 140 also serves as a handle, and the lifting body 110 is carried by holding the handle, which is convenient to operate. In addition, since the handle is located on the side of the lifting body 110 far away from the plug-in 120, the carrying operation process is labor-saving.

It should be noted that, in the infringement comparison, the "handle" may be a part of the "lifting body 110", that is, the "handle" and the "other part of the lifting body 110" are integrally formed; or a separate member that can be separated from the other parts of the lifting body 110, i.e., the handle can be manufactured separately and then combined with the other parts of the lifting body 110 into a whole. In one embodiment, as shown in fig. 4, the "handle" is a part of the "lifting body 110" that is integrally formed.

Referring to fig. 5 again, optionally, the handle 140 includes a first handle 141 and a second handle 142. The first lever 141 is connected to the second lever 142, the second lever 142 is connected to the lifting body 110, and the first lever 141 is located on the side of the lifting body 110 facing away from the insert 120. In this way, since the first handle 141 is located on the side of the lifting body 110 opposite to the plug-in unit 120, the lifting body 110 is transported by holding the first handle 141, which is more labor-saving and more convenient.

It should be noted that, in infringement contrast, the "first stem 141" may be a part of the "second stem 142", that is, the "first stem 141" and the "other part of the second stem 142" are integrally formed; or a separate member that is separable from the "other portion of second stem 142", i.e., "first stem 141" may be manufactured separately and then integrated with the "other portion of second stem 142". As shown in fig. 5, in one embodiment, first handle 141 is a part of second handle 142 that is integrally formed.

It should be noted that, in infringement comparison, the "handle 140" may be a part of the "lifting body 110", that is, the "handle 140" is integrally formed with the other parts of the "lifting body 110"; the handle 140, which may be a separate member from the other parts of the lifting body 110, may be manufactured separately and then integrated with the other parts of the lifting body 110. As shown in FIG. 5, in one embodiment, the "handle 140" is an integrally formed part of the "lifting body 110".

Referring to fig. 6, the lifting body 110 is shaped like a rod, and the lifting body 110 is protruded toward a side away from the insert 120 to form a handle 140. In this way, the raised portion of the lifting body 110 corresponds to the handle 140, and a serviceman usually holds the raised portion to perform work during transportation. Since the raised portion is located on the side of the lifting body 110 remote from the insert 120, it is labor-saving in handling the switch machine 200.

Referring again to FIG. 1, in one embodiment, the length of the insert 120 is a, and a is 35mm to 40 mm. Thus, the length of the plug-in 120 is adapted to the depth of the mounting hole 221 on the foot plate 220 of the switch machine 200, so that the plug-in 120 is completely located in the mounting hole 221, and when the switch machine is lifted, the plug-in 120 contacts with the hole wall of the mounting hole 221, the side surface of the end part of the lifting body 110 contacts with the plate surface of the foot plate 220, the two limiting members 130 synchronously contact with the two side surfaces of the corner part 210 respectively, the stress effect is good, and the slip phenomenon cannot occur in the operation process of the switch machine lifting device 100. In addition, the length of the insert 120 is not so long that the end of the lifting body 110 cannot contact the board surface of the foot board 220 (because the switch machine 200 is usually located on the ground, when the length of the insert 120 is greater than the depth of the mounting hole 221, the insert 120 will interfere with the ground, so that the end of the lifting body 110 cannot contact the board surface of the foot board 220), and thus the force effect between the lifting body 110 and the foot board 220 is poor; in addition, the length of the insert 120 is not too short to contact only a portion of the sidewall of the mounting hole 221, and the force is also poor.

Referring to fig. 1 again, in one embodiment, the distance between the plug 120 and the stopper 130 is s, and s is 18mm to 20 mm. In this way, when the insert 120 is inserted into the mounting hole 221 of the foot plate 220, the stopper 130 can simultaneously contact the side surface of the corner portion 210 of the switch machine 200. It should be noted that the distance between the plug 120 and the limiting member 130 depends on the installation position of the installation hole 221 on the foot plate 220.

Referring to fig. 1 again, in one embodiment, the position-limiting element 130 is a position-limiting element, and a distance h (also referred to as a height of the position-limiting element) between a top side and a bottom side of the position-limiting element is 65mm to 70 mm. Therefore, the height of the limiting plate is proper, the limiting plate is not too large or too small, and the limiting plate has better stress effect and is not easy to slip in the process of being respectively contacted with two side faces of the corner part 210 of the point switch 200.

Referring again to FIG. 1, in one embodiment, the length of the lifting body 110 is b, which is 45cm-65 cm. Thus, the length of the lifting and transporting main body 110 is suitable, the lifting and transporting main body is not too large or too small, maintenance personnel can lift and operate the switch machine 200, the maintenance personnel can avoid the switch machine 200, the switch machine 200 is prevented from falling to damage the maintenance personnel in the lifting and transporting process, and the safety is high.

Referring to fig. 1 again, in one embodiment, the lifting body 110, the plug 120 and the stopper 130 are made of stainless steel, iron, copper or hard alloy. Thus, the switch machine lifting device 100 has a good force bearing effect, and can realize the switch machine 200 with the carrying weight of about 150 KG. Of course, the lifting body 110, the plug 120 and the stopper 130 may be made of hard rubber, hard wood or other materials, and are not limited herein.

Referring to fig. 1 again, in one embodiment, the lifting body 110, the plug 120 and the limiting member 130 are an integrated structure. Of course, the lifting body 110, the insert 120 and the stopper 130 may be detachably connected together, and are not limited herein. For example, the lifting body 110 is provided with a first screw hole, the plug 120 is provided with a screw thread corresponding to the first screw hole, and the plug 120 is detachably mounted in the first screw hole. In addition, a second screw hole is formed on the lifting and transporting main body 110, the limiting member 130 is provided with a threaded insertion end corresponding to the second screw hole, and the limiting member 130 is installed on the lifting and transporting main body 110 through the threaded insertion end. For another example, the plug-in 120 may be detachably fixed to the lifting and transporting main body 110 by using a mounting member such as a pin, a rivet, a clamping member, and the like, and the limiting member 130 may also be detachably fixed to the lifting and transporting main body 110 by using a mounting member such as a pin, a rivet, a clamping member, and the like, which are not limited herein, as long as the plug-in 120 and the limiting member 130 can be fixed to the lifting and transporting main body 110, and are not described in detail.

It should be further noted that, in infringement comparison, the "insert 120" may be a part of the "lifting body 110", that is, the "insert 120" is integrally formed with the "other part of the lifting body 110"; the "insert 120" may be manufactured separately from the "other part of the lifting body 110" and may be combined with the "other part of the lifting body 110" as a single unit. In one embodiment, as shown in FIG. 1, the "insert 120" is a part of the "lift body 110" that is integrally formed.

It should be further noted that, in the infringement comparison, the "limiting member 130" may be a part of the "lifting body 110", that is, the "limiting member 130" is integrally formed with the other part of the "lifting body 110"; the "stopper 130" may be manufactured separately from the "other part of the lifting body 110" and then combined with the "other part of the lifting body 110" to form a single body. As shown in fig. 1, in one embodiment, the "limiting member 130" is a part of the "lifting body 110" that is integrally formed.
