[0030] In the related art, the mechanical and electrical equipment located at the edge of the factory building foundation has the technical problem of low disassembly efficiency. The hoist and the travelling crane provided by the embodiments of the present application can at least solve the technical problem of low disassembly efficiency of the mechanical and electrical equipment located at the edge of the factory building foundation to a certain extent.
[0031] The present application will be described below in conjunction with the drawings and specific embodiments:
[0032] The hoist 100 comprises a hoisting beam 110, a counterweight lifting lug 120, a hoisted object lifting lug 130, a main hook lifting lug 140 and a secondary hook lifting lug 150. The counterweight lifting lug 120 is arranged on one side of the length direction of the hoisting beam 110 and connected to the hoisting beam 110, used for connecting with the counterweight 200. The hoisted object lifting lug 130 is arranged on the other side of the length direction of the hoisting beam 110 and connected to the hoisting beam 110, used for connecting with the hoisted object 300. The main hook lifting lug 140 is connected to the hoisting beam 110, used for connecting with the main hook 400 of the travelling crane, and arranged on the side of the hoisted object lifting lug 130 close to the counterweight lifting lug 120. The secondary hook lifting lug 150 is connected to the hoisting beam 110, used for connecting with the secondary hook 500 of the travelling crane, and arranged on the side of the hoisted object lifting lug 130 close to the counterweight lifting lug 120.
[0033] The main hook lifting lug 140, the auxiliary hook lifting lug 150, the counterweight lifting lug 120 and the hoisted object lifting lug 130 are fixedly connected to the hoisting beam 110. The counterweight lifting lug 120 and the hoisted object lifting lug 130 are arranged on the two sides of the hoisting beam 110 along the length direction, so that the hoisted object 300 and the counterweight 200 are separated on the two sides of the hoisting beam 110 during hoisting, and the counterweight 200 has a certain spacing from the hoisted object 300, so as to avoid the contact between the counterweight 200 and the wall of the factory building during hoisting. The main hook lifting lug 140 and the auxiliary hook lifting lug 150 are arranged on the side of the hoisted object 300 close to the counterweight lifting lug 120, so that the main hook lifting lug 140 and the auxiliary hook lifting lug 150 are away from the hoisted object lifting lug 130, so that the main hook 400 and the auxiliary hook 500 can be away from the hoisted object 300 during formal hoisting, and the hoisted object 300 is lifted, so as to avoid the interference between the main hook 400 and the auxiliary hook 500 and the wall of the factory building, thereby facilitating the hoisting of the mechanical and electrical equipment located at the edge of the factory building by the travelling crane. After the design of the present application, the mechanical and electrical equipment located at the edge of the factory building can be lifted by using the existing travelling crane in the factory building and combining the lifting appliance 100 of the present application, without the need to set up multiple inverted chains for lifting. The safety performance of the hoisting process is higher, and since multiple inverted chains do not need to be set up and installed on the steel structure of the factory building according to the designed position, the disassembly efficiency of the mechanical and electrical equipment located at the edge of the factory building is higher, which helps to improve the production efficiency of the enterprise.
[0034] In some embodiments, along the length direction of the hoisting beam 110, the main hook lifting lug 140 is arranged between the counterweight lifting lug 120 and the hoisted object lifting lug 130. The counterweight 200 and the hoisted object 300 are connected to the counterweight lifting lug 120 and the hoisted object lifting lug 130 respectively, and the main hook lifting lug 140 lifts the hoisted object 300 while lifting the counterweight 200. When the main hook lifting lug 140 is located between the counterweight lifting lug 120 and the hoisted object lifting lug 130, the lifting force can be more evenly distributed during hoisting, the stress concentration on the hoisting beam 110 is reduced, and the overall stability and safety of the hoisting structure are improved.
[0035] Before the hoisting of the hoisted object 300, the main hook 400 and the auxiliary hook 500 need to simultaneously apply force to hoist the hoisting appliance 100 and the counterweight 200 thereon, and move the hoisting appliance 100 to the side of the hoisted object 300. Since the counterweight lifting lug 120 is arranged on the side away from the hoisted object lifting lug 130, and the main hook lifting lug 140 is arranged between the counterweight 200 lifting lug and the hoisted object lifting lug 130, if the auxiliary hook lifting lug 150 is not arranged well, when the hoisting appliance 100 and the counterweight 200 are hoisted, the hoisting appliance 100 will be tilted upward on the side of the hoisted object lifting lug 130 due to uneven force on both sides in the length direction, making it difficult for the hoisted object lifting lug 130 to be connected with the hoisted object 300. Therefore, in some embodiments, the counterweight lifting lug 120 is arranged between the main hook lifting lug 140 and the auxiliary hook lifting lug 150 in the length direction of the hoisting beam 110. After such design, the auxiliary hook lifting lug 150, the counterweight lifting lug 120, the main hook lifting lug 140 and the hoisted object lifting lug 130 are arranged in sequence in the length direction of the hoisting beam 110. During the hoisting of the hoisting appliance 100 and the counterweight 200, the counterweight 200 is located between the main hook 400 and the auxiliary hook 500, and different forces are applied to the main hook 400 and the auxiliary hook 500, so as to balance the counterweight 200 and the hoisting beam 110, and make the hoisting beam 110 in a horizontal state, preventing the hoisting beam 110 from being tilted upward on the side of the hoisted object lifting lug 130, and facilitating the connection between the hoisted object lifting lug 130 and the hoisted object 300.
[0036] It is easy to understand that the main hook 400 and the main hook lifting lug 140, the auxiliary hook 500 and the auxiliary hook lifting lug 150, the hoisted object 300 and the hoisted object lifting lug, the counterweight 200 and the counterweight lifting lug 120 can be directly connected or indirectly connected through a steel wire rope, a hoisting belt or the like, which is not limited in the present application.
[0037] In some embodiments, the auxiliary hook lifting lug 150 is also used to connect with the counterweight 200. The auxiliary hook lifting lug 150 also serves as a connection for the counterweight 200, so that the counterweight 200 can be hung on the counterweight lifting lug 120 or the auxiliary hook lifting lug 150, and the position of the counterweight 200 on the hoisting beam 110 can be flexibly adjusted according to the weight of the counterweight 200, the weight of the hoisted object 300, etc., facilitating the user to hoist different hoisted objects 300 through the hoisting appliance 100.
[0038] In some embodiments, the counterweight lifting lug 120 is also used to connect with the auxiliary hook 500 of the travelling crane. The counterweight lifting lug 120 also serves as a connection for the auxiliary hook 500, so that the auxiliary hook 500 can be hung on the counterweight lifting lug 120 or the auxiliary hook lifting lug 150, and the position of the auxiliary hook 500 on the hoisting beam 110 can be flexibly adjusted according to the weight of the counterweight 200, the position of the counterweight 200, the weight of the hoisted object 300, etc., facilitating the user to hoist different hoisted objects 300 through the hoisting appliance 100.
[0039] In some embodiments, a plurality of weight lifting lugs 120 are provided, which are spaced along the length direction of the hoisting beam 110. The weight 200 can be hung on the weight lifting lugs 120 at different positions, so that the position of the weight 200 on the hoisting beam 110 can be flexibly adjusted according to the weight of the weight 200, the weight of the hoisted object 300, etc., facilitating the user to hoist different hoisted objects 300 by the lifting appliance 100.
[0040] In some embodiments, a plurality of hoisted object lifting lugs 130 are provided, which are spaced along the length direction of the hoisting beam 110.

[0041] In some embodiments, three weight lifting lugs 120 and four hoisted object lifting lugs 130 are provided, which are all spaced along the length direction of the hoisting beam 110.
[0042] In some embodiments, a plurality of main hook lifting lugs 140 are provided, which are spaced along the length direction of the hoisting beam 110. The main hook 400 can be hung on the main hook lifting lugs 140 at different positions, so that the position of the main hook 400 on the hoisting beam 110 can be flexibly adjusted according to the weight of the weight 200, the weight of the main hook 400, etc., facilitating the user to hoist different main hooks 400 by the lifting appliance 100.
[0043] In some embodiments, two main hook lifting lugs 140 are provided, and the main hook 400 is connected to the two main hook lifting lugs 140 at the same time.
[0044] In some embodiments, the main hook lifting lug 140, the auxiliary hook lifting lug 150, the weight lifting lug 120 and the hoisted object lifting lug 130 are all in a columnar shape, and a plurality of mounting through holes are formed on the hoisting beam 110, each lug is arranged in the mounting through hole and is welded with the hoisting beam 110, and the two ends of each lug are arranged outside the hoisting beam 110, and each lug is connected with the corresponding component through the part outside the hoisting beam 110.
[0045] The following describes the use method of the lifting appliance 100:
