Description

Technical Field

[0001] This utility model relates to the field of crane hook structure technology, and in particular to a crane hook that is easy to connect. Background Technology

[0002] Crane hooks are the most common type of lifting device on cranes. Hooks are usually suspended from the wire rope of the hoisting mechanism by means of pulley blocks and other components. Crane hooks are key components in lifting equipment that are directly connected to the object being lifted. When using crane hooks, it is necessary to make them easy to connect and install so that they can be easily disassembled and replaced when they malfunction.

[0003] A search revealed that patent announcement number CN219009709U discloses a crane hook that is easy to connect. This application includes a pulley block and a wheel seat. A fixing rod is rotatably connected to the lower surface of the wheel seat. A fixing block is welded to the end of the fixing rod away from the wheel seat. A groove is formed inside one side of the fixing block. A hook is slidably connected to the inner surface of the groove. A fixing plate is engaged inside the groove of the fixing block. A threaded hole one and a threaded hole two are formed on the side of the fixing plate away from the fixing block. A screw is threaded into the first threaded hole of the fixing plate. The external thread of the screw passes through the fixing plate and connects to the inside of the fixing block. The hook is fixed using two sets of screws instead of the traditional multiple sets of fastening bolts, improving the work efficiency of workers when installing and connecting the hook. Since the force point of the hook during use is the bottom of the inner wall of the groove in the fixing block, the screw will not bend during use, thus improving the work efficiency of workers when installing the hook again.

[0004] However, existing crane hooks cannot be easily and quickly installed or disassembled when malfunctions occur. At the same time, crane hooks do not have good protective effects, so they are prone to rusting and cleaning after long-term use, which affects the efficiency of disassembly. Therefore, there is an urgent need in the market for a crane hook that is easy to connect to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a crane hook that is easy to connect, so as to solve the problems mentioned in the background art, that existing crane hooks cannot be easily and quickly installed and disassembled when malfunctions, and that crane hooks do not have good protective effects, which makes them prone to rusting and cleaning after long-term use, thus affecting the efficiency of disassembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A crane hook that is easy to connect includes two side plates. A pulley shaft is installed between the side plates, and pulleys are installed at both ends of the pulley shaft. Protective shells are installed on the outside of the pulleys. A mounting bearing is installed below the pulley shaft, and a hook body is installed below the mounting bearing. A limit seat is provided at the upper end of the hook body, and a threaded seat is provided at the upper end of the limit seat. A fixed seat is installed on the outside of the threaded seat, and a sealing cap is installed above the fixed seat. The sealing cap has a threaded connection groove inside that corresponds to the threaded seat.

[0008] Preferably, one end of the protective shell is provided with a fixing foot, the lower fixing foot is fixedly connected to the side plate by a fixing bolt, the upper fixing foot is fixedly connected to the side plate by a connecting rod, one end of the connecting rod connected to the side plate is provided with a limit nut, and the other end of the connecting rod connected to the side plate is provided with a fixing nut.

[0009] Preferably, the mounting bearing is fixedly connected to the side plate by fastening screws.

[0010] Preferably, the inner wall of the threaded seat is provided with an installation through hole, the limiting seat and the hook structure are an integral structure, and the threaded seat and the limiting seat are an integral structure.

[0011] Preferably, one end of the threaded seat passes through the mounting bearing and extends to the outside of the mounting bearing, and the threaded seat and the mounting bearing are fixedly connected by a fixing seat.

[0012] Preferably, the fixed base has a threaded groove inside that corresponds to the threaded seat, and the outer wall of the fixed base has a second mounting through hole inside that corresponds to the first mounting through hole. The upper end of the fixed base has a threaded connecting seat, and the threaded connecting seat and the fixed base are an integral structure.

[0013] Preferably, a fixing rod is installed between the fixing seat and the threaded seat. One end of the fixing rod passes through the first mounting through hole of the threaded seat and the second mounting through hole of the fixing seat and extends to the outside of the fixing seat. Both ends of the fixing rod are provided with fixing ends, and fastening nuts are installed on the outside of the fixing ends.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model uses a threaded seat on the hook body to pass through the mounting bearing, and then uses a rotating fixed seat to fix the threaded seat and the mounting bearing. At this time, the first mounting through hole and the second mounting through hole are on the same horizontal plane. Then, the fixing rod passes through the threaded seat and the fixed seat respectively, and both ends of the fixing rod are equipped with fastening nuts. This can further limit the threaded seat and prevent the hook body and the mounting bearing from easily falling off and separating. This method can facilitate the connection and installation of the crane hook, making the crane hook connection more secure.

[0016] (2) This utility model installs the sealing cap on top of the fixed seat by rotating the sealing cap. This can prevent dust from falling at the connection between the fixed seat and the threaded seat, thus affecting the disassembly efficiency of the fixed seat. When the hook structure is damaged after a long period of use, and it is inconvenient to rotate and disassemble the fixed seat and the threaded seat due to the long time, the sealing cap can be opened by rotating to easily add lubricating oil between the fixed seat and the threaded seat. This makes it easy to disassemble the fixed seat and the threaded seat, and thus makes it easy to disassemble and replace the hook structure. Attached Figure Description

It should be noted that, in order to save space and highlight the innovative elements of this patent, such as how the crane hook is used and the working principle and process of how the pulley shaft drives the pulley to rotate, it will not be described in detail in this patent.

[0024] See Figure 1 One end of the protective shell 4 is provided with a fixing foot 401. The lower fixing foot 401 is fixedly connected to the side plate 1 by a fixing bolt 8. The upper fixing foot 401 is fixedly connected to the side plate 1 by a connecting rod 5. One end of the connecting rod 5 is provided with a limit nut 6 at the connection point with the side plate 1, and the other end of the connecting rod 5 is provided with a fixing nut 7. The fixing bolt 8 can be used to easily install and fix the fixing foot 401 to the side plate 1. The connecting rod 5 and the limit nuts 6 and fixing nuts 7 at both ends of the connecting rod 5 can fix the fixing foot 401 to the side plate 1 and provide limiting support between the two side plates 1.

[0025] See Figure 2 and Figure 4The threaded seat 1102 has an internal mounting through hole 1103 on its outer wall. The limiting seat 1101 and the hook structure 11 are integrally formed. The threaded seat 1102 and the limiting seat 1101 are integrally formed. One end of the threaded seat 1102 passes through the mounting bearing 9 and extends to the outside of the mounting bearing 9. The threaded seat 1102 and the mounting bearing 9 are fixedly connected by a fixing seat 12. The fixing seat 12 has an internal threaded groove 1201 corresponding to the threaded seat 1102. The internal wall of the fixing seat 12 has an internal mounting through hole 1202, which corresponds to the mounting through hole 1103. A threaded connecting seat 1203 is provided at the upper end of the fixing seat 12. The threaded connecting seat 1203 and the fixing seat 12 are integrally formed. A fixing rod 13 is installed between the fixing seat 12 and the threaded seat 1102. One end of the fixing rod 13 passes through... The mounting through hole 1103 provided in the threaded seat 1102 and the mounting through hole 1202 provided in the fixed seat 12 extend to the outside of the fixed seat 12. Both ends of the fixing rod 13 are provided with fixing ends 1301, and fastening nuts 14 are installed on the outside of the fixing ends 1301. The fixed seat 12 can facilitate the installation and fixation between the threaded seat 1102 and the mounting bearing 9. At this time, the mounting through hole 1202 and the mounting through hole 1103 are located on the same horizontal plane. Then, by passing the fixing rod 13 through the threaded seat 1102 and the fixed seat 12 respectively, and then fixing them with fastening nuts 14, the threaded seat 1102 and the fixed seat 12 can be installed and fixed, which can prevent the threaded seat 1102 and the mounting bearing 9 from falling off and separating, thus avoiding a large safety hazard for the crane hook.

[0026] Working principle: In use, the threaded seat 1102 of the hook body 11 passes through the mounting bearing 9, and then the fixed seat 12 is rotated to fix the threaded seat 1102 and the mounting bearing 9. This prevents the hook body 11 from falling off and separating from the mounting bearing 9. At this time, the first mounting through hole 1103 and the second mounting through hole 1202 are on the same horizontal plane. Then, the fixing rod 13 passes through the threaded seat 1102 and the fixed seat 12 respectively, and both ends of the fixing rod 13 are equipped with fastening nuts 14. This further limits the threaded seat 1102 and prevents the hook body 11 from easily falling off from the mounting bearing 9. In the case of separation, the sealing cap 15 is installed on top of the fixed seat 12 by rotating the sealing cap 15. This can prevent dust from falling at the connection between the fixed seat 12 and the threaded seat 1102, thus affecting the disassembly efficiency of the fixed seat 12. When the hook structure 11 is damaged after a long period of use, and it is inconvenient to rotate and disassemble the fixed seat 12 and the threaded seat 1102 due to the long time, the sealing cap 15 can be opened by rotating it to easily apply lubricating oil between the fixed seat 12 and the threaded seat 1102. This makes it easy to disassemble the fixed seat 12 and the threaded seat 1102, and thus makes it easy to disassemble and replace the hook structure 11.
