It is strictly controlled in heat treatment process, temperature and time after being formed by machining.
[0003] In the hoisting equipment, the hook plays a crucial role, and is a necessary hoisting equipment transportation component. The hook has been widely used in various fields, and the structure of the hook is various. Because of different purposes, single-hook and double-hook are the most common two structure forms, but they cannot be used interchangeably. Under special conditions, frequent replacement of lifting appliance and hook greatly limits the improvement of work efficiency.
[0004] In the prior art, the hook generally needs to be used with a lifting handle assembly during use. The hook and the lifting handle assembly are connected by a connecting shaft to realize rotation connection. However, in actual use, the shafting is prone to deformation due to large stress during hoisting. Generally, a shaft sleeve is used to realize rotation connection. The contact part of the shaft sleeve and the lifting handle assembly is prone to wear during long-term use. Especially after excessive wear of the lifting handle assembly, the lifting handle assembly needs to be replaced, which is high in cost. UTILITY MODEL CONTENT

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] See Figures 1-4 This embodiment discloses a combined lifting handle assembly, including a lifting handle body 101, a connecting shaft 102, and a connecting component 103 disposed on the lifting handle body 101.
[0034] The handle body 101 includes a handle shaft 104 and a first connecting part 105 and a second connecting part 106 disposed at one end of the handle shaft 104. The first connecting part 105 and the second connecting part 106 are arranged in parallel. The other end of the handle shaft 104 is connected to the connecting assembly 103.
[0035] Mounting holes 107 are provided at opposite positions on the first connecting part 105 and the second connecting part 106. Fixing components 108 are detachably provided on the first connecting part 105 and the second connecting part 106. Fixing components 108 include end caps 109 and bushings 110. An extension 111 is provided on the end cap 109. After the end cap 109 is installed on the first connecting part 105 and the second connecting part 106, the extension 111 cooperates with the mounting holes 107. The bushings 110 are installed in the extension 111. Both ends of the connecting shaft 102 cooperate with the bushings 110 in the fixing components 108 on both sides of the first connecting part 105 and the second connecting part 106, respectively.
[0036] In practical use, this utility model is mainly used to connect hooks. The fixing component 108 in this application is used to fix the connecting shaft 102, thereby achieving connection with the hook. An extension 111 is provided on the end cap 109, which is fixedly connected to the first connecting part 105 and the second connecting part 106. A bushing 110 is installed inside the extension 111, allowing the bushing 110 to contact the connecting shaft 102 and the extension 111. This design avoids direct contact between the bushing 110 and the first connecting part 105 and the second connecting part 106, preventing wear. After long-term use, only the end cap 109 needs to be replaced. Replacing and installing the end cap 109 is more convenient and less costly than replacing the worn handle body 101. Furthermore, it eliminates the need to disassemble the connecting component 103, shortening replacement time and improving replacement efficiency.
[0037] The end cap 109 is detachably connected to the first connecting part 105 and the second connecting part 106 by a number of screws 112. The use of screws 112 for connection makes disassembly and assembly more convenient.
[0038] Furthermore, in some preferred embodiments, a wear-resistant pad is provided on the end cap 109 near the rotating shaft. The end cap 109 serves to limit the movement of the connecting shaft 102. During use, the connecting shaft 102 and the end cap 109 are prone to friction, and the wear-resistant pad can provide good wear resistance.
[0039] Furthermore, the lifting shaft 104, the first connecting part 105, and the second connecting part 106 are an integral structure.
[0040] The upper end of the lifting shaft 104 has a stepped structure, and the connecting component 103 is located at the shoulder of the lifting shaft 104.
[0041] In some preferred embodiments, the connecting assembly 103 includes a base 113, a connecting seat 114, and an annular support platform 115. The base 113 is provided with a through hole 116. The connecting seat 114 is provided with a recess 117 on the side near the upper base 113. The connecting seat 114 is provided with a threaded hole 118. The upper end of the lifting shaft 104 is provided with an external thread. The lifting shaft 104 passes through the through hole 116 and is threadedly connected to the threaded hole 118 on the connecting seat 114. The annular support platform 115 is located in the recess 117 and its lower end contacts the base 113. A lifting arm 119 is provided on the side of the base 113.
[0042] The annular support platform 115 can distribute pressure to the base 113, avoiding stress concentration during use.
[0043] Furthermore, the connecting assembly 103 also includes a support ring 120, which is located between the annular support platform 115 and the connecting seat 114. The width of the support ring 120 is greater than the width of the annular support platform 115. The support ring 120 can increase the contact surface with the base 113 and further disperse the pressure.
[0044] In some preferred embodiments, the cross-section of the bearing ring 120 is trapezoidal, with the upper end of the bearing ring 120 contacting the annular support platform 115 and the lower end contacting the connecting seat 114.
[0045] Furthermore, both the end face of the lifting shaft 104 and the upper end face of the connecting seat 114 are provided with positioning grooves 121. After the lifting shaft 104 is connected to the connecting seat 114, the positioning grooves 121 on the end face of the lifting shaft 104 and the upper end face of the connecting seat 114 are aligned with each other, and a limit block 122 is fixedly installed in the positioning groove 121 by screws 112. This improves the connection stability between the lifting shaft 104 and the connecting seat 114 and prevents them from rotating.
[0046] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
