Description

Technical Field

[0001] The utility model belongs to the technical field of light and small lifting equipment, and in particular relates to an intelligent hook assembly. Background Art

[0002] Electric hoists include chain electric hoists, wire rope electric hoists, mini electric hoists, micro electric hoists, combined chain electric hoists, winches, multi-functional hoists, etc. Electric hoists are a special lifting equipment installed on overhead cranes and gantry cranes. Electric hoists are characterized by small size, light weight, simple operation and easy use. They are mainly used in major factories, warehouses, wind power generation, logistics, docks, construction and other industries for lifting or loading and unloading goods. They can also lift heavy objects for convenient work or repair of large machines.

[0003] The electric hoist is mainly composed of a reducer, an operating mechanism, a drum device, a hook device, a coupling, etc. The hook assembly, as an important part connecting the drum device and the hook device, has a great influence on the stability and safety during the lifting process.

[0004] The Chinese utility model patent with patent announcement number CN211419369U and announcement date 2014.12.17 discloses a load detection device for a tower crane, the structure of which includes a mounting plate and a base plate, a first mounting column, a second mounting column, a weighing sensor, a first threaded rod and a second threaded rod, a data wire, a baffle, a weighing display panel, a shock-absorbing spring, two connecting plates, a first fixing bolt, a hook, a supporting side plate, a partition plate, a second fixing bolt, a hanging wire drum, and a limit fixing rod.

[0005] The load detection device in this utility model patent has the following general structural principle: the weighing sensor is arranged between the mounting plate and the base plate, and the upper and lower parts of the weighing sensor are respectively fixedly connected to the first threaded rod and the second threaded rod, and the threaded rod is screwed to the mounting column. By arranging the weighing sensor and the weighing display board above the hook, when the tower crane lifts the object, the weighing sensor can detect the load value at any time, and display the load value through the weighing display board. When the load exceeds the load range, the overload alarm fixedly installed on the right side of the weighing display board can give an alarm in time to remind the staff to adjust the weight of the device objects in time. The shock-absorbing spring provides shock-absorbing protection for the weighing sensor. The hook is fixed to the base plate with the first fixing bolt, and the hanging wire drum is fixed to the second fixing bolt on the supporting side plate, and is limited by the limiting fixing rod.

[0006] However, in actual use, the load detection device still has at least the following two shortcomings, in other words, which are the technical problems to be solved by the present utility model.

[0007] 1. The load cell of the load detection device is fixed to the hook. During the lifting process, as the weight and lifting height increase, the possibility of the hook rotating due to the weight increases, causing the wire of the wire drum to tangle, affecting the normal operation of the machine and the safety of the staff.

[0008] 2. The weighing sensor of the load detection device is fixed to the hook and the hanging wire drum, so that the weighing sensor and the weighing display board cannot rotate independently. When the observer is not at the right angle to the weighing display board, it is impossible to read the reading quickly, which increases the difficulty of use.

[0009] Therefore, in summary, there is an urgent need for a new intelligent hook assembly in which the hook can rotate and the weighing control device can rotate independently, so as to solve the barriers of the existing technology. Utility Model Content

[0010] The utility model provides an intelligent hook assembly, which can be achieved by arranging a hook rotating column unit and a chain rotating rod unit on a weighing machine: 1. The weighing machine is movably connected with the hook rotating column unit, and the rotation of the weight during the lifting process will not affect the weighing machine or the chain, and the interference to the machine is small; 2. The weighing machine is movably connected with the chain rotating rod unit and the hook rotating column unit, and the weighing machine can rotate independently, and the observer can read the value at any angle, with a simple structure and easy use.

[0011] The utility model adopts the technical solution to solve the above problems: the structure includes a weighing device, a hook rotating column unit respectively arranged on the lower end surface of the weighing device, and a chain rotating rod unit arranged on the upper end surface of the weighing device.

[0012] A further preferred technical solution is that the hook rotating column unit includes a threaded rod threadedly arranged on the lower end surface of the weighing device, a slotted rotating sleeve sleeved on the threaded rod and used for connecting the hook, an end limit block arranged on the threaded rod, and a thrust ball bearing sleeved on the threaded rod and supporting the slotted rotating sleeve.

[0014] A further preferred technical solution is that the hook rotating column unit also includes a supporting cross bar arranged on the slotted rotating sleeve and used for connecting the hook.

[0015] A further preferred technical solution is that the hook rotating column unit also includes a reinforcing bottom plate which is arranged on the lower end surface of the end stop block and is used to fix the slotted rotating sleeve.

[0016] A further preferred technical solution is that the hook rotating column unit also includes a locking nut arranged on the supporting cross bar and used for connecting to the slotted rotating sleeve.

[0017] A further preferred technical solution is that the chain rotating rod unit also includes a limit pin disposed in the chain jacket and used to clamp the chain.

[0018] A further preferred technical solution is that: a Bluetooth cover is also provided on the weighing device.

[0019] A further preferred technical solution is that a perforated fixing plate for sleeve-engaging the T-shaped rotating threaded rod is provided in the weighing device.

[0020] A further preferred technical solution is that the weighing device is also provided with a function expansion joint and a spiral wire interface for connecting the spiral wire. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0034] As attached Figure 1-7 As shown, an intelligent hook assembly comprises a weighing device 11, a hook rotating column unit 1 respectively arranged on the lower end surface of the weighing device 11, and a chain rotating rod unit 2 respectively arranged on the upper end surface of the weighing device 11.

[0035] In this embodiment, the weighing device 11 is a prior art, and mainly includes a tension and pressure sensor, a control circuit board, a housing and a digital display board. The weighing device 11 is used to transmit the tension and pressure change data at both ends to the control circuit board, and then display the weight on the digital display board for easy reading. The main function of the housing is to protect and fix the various parts.

[0036] In addition, the function of the hook rotating column unit 1 is to flexibly connect the weighing device 11 and the hook a so that the rotational freedom between the hook and the weighing device 11 will not interfere with each other, and the rotation of the weight on the hook will not affect the chain b and the spiral line c, and will not interfere with the normal operation of other components of the machine. The structure is simple and safe to use.

[0037] Finally, the chain rotating rod unit 2 is used to flexibly connect the chain b and the weighing machine 11, so that the rotational freedom of the upper and lower connections of the weighing machine 11 is not restricted and can rotate independently of other structures. When the user is behind the digital display board of the weighing machine 11 or at an angle that is difficult to observe, the user only needs to rotate the weighing machine 11 so that the digital display board faces the observer. It is convenient and flexible to use. At the same time, the weighing machine 11 is mostly connected to the chain hoist host d through the spiral line c. After the weighing machine 11 can rotate independently, the spiral line c and the chain hoist host d are less affected by other structures, and the service life of the machine will also be extended.

[0038] The hook rotating column unit 1 includes a threaded rod 101 threadedly arranged on the lower end surface of the weighing device 11, a slotted rotating sleeve 102 sleeved on the threaded rod 101 and used for connecting the hook a, an end limit block 103 arranged on the threaded rod 101, and a thrust ball bearing 104 sleeved on the threaded rod 101 and supporting the slotted rotating sleeve 102.

[0039] In this embodiment, the weighing device 11 is provided with a threaded hole for screw connection, one end of the threaded hole is connected to the hook rotating column unit 1, and the other end is connected to the chain rotating rod unit 2. In order to further strengthen it, spring washers can be added at the two ends of the connection, and thread glue can be injected. The screw rod 101 is used to screw the weighing device 11, the slotted rotating sleeve 102 is inserted on the screw rod 101, and the downward freedom is limited by the end stop block 103. The lower end of the slotted rotating sleeve 102 is used to connect with the hook a. At the same time, the thrust ball bearing 104 is sleeved on the screw rod 101 and clamped by the end stop block 103 and the slotted rotating sleeve 102, so that the slotted rotating sleeve 102 can rotate freely relative to the screw rod 101, and the structure is simple and stable.

[0040] The chain rotating rod unit 2 includes a T-shaped rotating threaded rod 201 threadedly arranged on the weighing device 11, a chain clamping sleeve 202 sleeved on the T-shaped rotating threaded rod 201 and used to fix the chain b, and a bearing 203 arranged on the chain clamping sleeve 202 and used to sleeve the T-shaped rotating threaded rod 201.

[0041] In this embodiment, the T-shaped rotating threaded rod 201 is used to screw the weighing device 11 and is clamped by the chain sleeve 202, but it does not affect the rotational freedom between the chain sleeve 202 and the T-shaped rotating threaded rod 201. Similarly, the bearing 203 is sleeved between the chain sleeve 202 and the T-shaped rotating threaded rod 201 to make the rotation more flexible. At the same time, a groove for fixing the chain b is provided in the chain sleeve 202, so that the chain b and the weighing device 11 can be flexibly connected, and each structure can rotate independently. The overall structure is simple and firm, which increases the user experience and improves the service life of the machine.

[0042] The hook rotating column unit 1 further includes a supporting cross bar 105 which is arranged on the slotted rotating sleeve 102 and is used to connect the hook a.

[0043] In this embodiment, the supporting cross bar 105 is inserted into the slotted rotating sleeve 102, and the hook a is mounted on the slotted rotating sleeve 102, so that the connection between the slotted rotating sleeve 102 and the hook a is more secure, and the hook a of different specifications can be installed according to the type of cargo, which has strong flexibility, and the hook a can use a safer eye-type self-locking hook.

[0044] The hook rotating column unit 1 further includes a reinforcing bottom plate 106 which is arranged on the lower end surface of the end stop block 103 and is used to fix the slotted rotating sleeve 102 .

[0045] In this embodiment, the reinforcement base plate 106 is disposed in the groove of the slotted rotating sleeve 102 and is further fixed to the slotted rotating sleeve 102 by screws to enhance the connection firmness of the slotted rotating sleeve 102 .

[0046] The hook rotating column unit 1 further includes a locking nut 107 which is arranged on the supporting cross bar 105 and is used to connect to the slotted rotating sleeve 102 .

[0047] In this embodiment, the support cross bar 105 is used to connect the hook a, which is easily loosened due to force during use. By providing the locking nut 107 on the support cross bar 105, the hook a can be prevented from slipping due to the loosening of the support cross bar 105.

[0048] The chain rotating rod unit 2 further includes a limiting pin 204 which is disposed in the chain jacket 202 and is used to clamp the chain b.

[0049] In this embodiment, the limiting pin 204 is inserted into the chain b to clamp the chain b and strengthen the connection stability between the chain jacket 202 and the chain b.

[0050] The weighing device 11 is also provided with a Bluetooth cover plate 12 .

[0051] In this embodiment, the Bluetooth cover 12 is connected to the control circuit board in the weighing device 11, so that the mobile phone can directly receive the force information of the weighing device 11, and can also communicate with the chain hoist host d through the spiral line c, so that the mobile phone can be used instead of the operating handle e to issue commands to the chain hoist.

[0052] The weighing device 11 is provided with a perforated fixing plate 13 for sleeve-engaging the T-shaped rotating threaded rod 201 .

[0053] In this embodiment, the hole fixing plate 13 makes the connection between the weighing device 11 and the T-shaped rotating threaded rod 201 more firmly and enhances stability. The hole fixing plate 13 can be set on the inner surface or the outer surface of the weighing device 11.

[0054] The weighing device 11 is also provided with a function expansion joint 14 and a spiral wire interface 15 for connecting the spiral wire c.

[0055] In this embodiment, the spiral wire interface 15 is used to connect the spiral wire c on the chain hoist host d, so that the chain hoist host d can maintain control communication with the spiral wire interface 15, and the spiral wire c is fixed by a spiral wire fixing clip 205 to prevent the spiral wire c from winding. The purpose of adding the functional expansion connector 14 is to meet other requirements of customers for the chain hoist as a reserve data connection port, and the function button 16 can be set on the weighing device 11. The function button 16 is connected to the control circuit board in the weighing device 11 and can issue instructions to the chain hoist host d so that the chain hoist can enter a suspended state. After entering the suspended state, when the user presses or supports the weight lightly with his hand, the front and rear forces of the weight change, so that the chain hoist can intelligently enter an ascending or descending motion, and can be operated with one button. To prevent the chain hoist from running due to accidental touch or external force, it is only necessary to turn off the function of the function button 16, which is simple and intelligent to operate.

[0056] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model.
