[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] A specific embodiment of this utility model provides a comprehensive control device for a chain crane, as shown in the attached figure. Figure 1 - Appendix Figure 4As shown, the device mainly includes a connecting part 1, a first connecting member 2, a second connecting member 3, a sliding part 4, an inductive switch 5, and a control board 6. The connecting part 1 has the first connecting member 2 at one end and the second connecting member 3 at the other end. The first connecting member 2 and the second connecting member 3 at both ends connect to the suspended part of the chain crane, thus integrating the chain crane's comprehensive control device onto the suspended part. In actual use, operation is only required on one suspended part. The sliding part 4 is slidably mounted on the connecting part 1. One of the moving terminal 7 and the contact point 8 of the inductive switch 5 is mounted on the sliding part 4, and the other is mounted on the connecting part 1. The slidable arrangement of the sliding part 4 enables control of the suspended part. The control board 6 is mounted on the connecting part 1, and the inductive switch 5 is connected to the control board 6. Pushing the sliding part 4 moves the moving terminal 7, and the movement between the moving terminal 7 and the contact point 8 causes the inductive switch 5 to generate an inductive signal, which is transmitted to the control board 6. The control board 6 generates a lower-level control signal based on the inductive signal and sends it to the drive motor of the chain crane to control the lifting and lowering of the suspended part. The control method of integrating the control switch into the suspension part in this application enables an operator to easily complete the suspension and transfer of items by a single person, making the operation more convenient.

[0025] In specific embodiments of this application, in conjunction with the appendix Figure 1 and attached Figure 2 As shown, the connecting part 1 includes a connecting rod 9 and a mounting shell 10. The two ends of the connecting rod 9 are connected to the first connecting member 2 and the second connecting member 3, respectively. The mounting shell 10 is disposed on the connecting rod 9. The sliding part 4 is slidably sleeved on the connecting rod 9 and can move along the length of the connecting rod 9. In practice, the connecting rod 9 is vertically arranged. The first connecting member 2 is disposed at the bottom of the connecting rod 9, and the second connecting member 3 is disposed at the top of the connecting rod 9. The control plate 6 is disposed inside the mounting shell 10, and the sliding part 4 has a handle-like structure sleeved on the connecting rod 9. The outer surface of the sliding part 4 has anti-slip textures for easy gripping by the operator. After the operator grasps the sliding part 4, sliding it upwards or downwards triggers the inductive switch 5, generating a corresponding signal that is sent to the control board 6. When the operator slides the sliding part 4 upwards, the inductive switch 5 generates an upward signal, which is fed back to the control board 6. The control board 6 then generates an upward control signal based on the upward signal and sends it to the drive motor of the chain crane to control the suspended part to rise. Conversely, when the operator slides the sliding part 4 downwards, the inductive switch 5 generates a downward signal, which is fed back to the control board 6. The control board 6 then generates a downward control signal based on the downward signal and sends it to the drive motor of the chain crane to control the suspended part to descend. During the suspension process, the operator can also simultaneously push the chain crane's integrated control device laterally upwards to move the suspended item to a designated location.

[0026] Since the induction switch 5 and the control board 6 are conventional technical solutions, they will not be described in detail.

[0027] In some embodiments, the device further includes a guide rod 11 and a reset member 12. The guide rod 11 is provided inside the mounting housing 10, and a guide hole is provided on the sliding part 4. The guide rod 11 passes through the guide hole, and the reset member 12 is provided between the mounting housing 10 and the sliding part 4. In this way, the sliding direction of the sliding part 4 can be restricted by the guide rod 11 to prevent the sliding part 4 from shaking randomly. Moreover, the reset member 12 can be used to return the sliding part 4 to its original position when no operation is performed.

[0028] The guide rods 11 are multiple and arranged circumferentially along the sliding part 4 to ensure the stability of the connection between the sliding part 4 and the connecting part 1. The reset member 12 can be a spring, which is sleeved on the guide rod 11. One end of the guide rod 11 is connected to the mounting shell 10, and the other end is provided with a clamping cap 13. The sliding part 4 is provided with a clamping head 14, which is arranged circumferentially at one end of the sliding part 4. The clamping head 14 can be a block-shaped protrusion structure. A guide hole is provided on the clamping head 14, and the direction of the guide hole is the same as the direction of the connecting rod 9. The two ends of the clamping head 14 are respectively connected to the mounting shell 10 and the clamping cap 13 through springs. There are limiting grooves at the opening positions of the guide holes at both ends of the clamping head 14, and the spring is located in the limiting groove.

[0029] Specifically, in this application, the first connecting member 2 is a lower lifting member, which is located at the lower end of the connecting part 1. The second connecting member 3 is a tension rotating ring, which is rotatably connected to the connecting rod 9. The tension rotating ring and the connecting rod 9 can be rotatably connected through a bearing.

[0030] The specific tension-bearing swivel ring includes an inner connector, a thrust bearing, a connecting disc, and an outer connector. One end of the inner connector has an internal thread for threaded connection with the connecting rod 9. The other end of the inner connector has a first convex ring with an increased diameter. The outer diameter of this first convex ring is larger than the inner diameter of the thrust bearing. The thrust bearing is fitted onto the inner connector, with its top end abutting against the lower ring surface of the first convex ring. The connecting disc has a mounting hole inside, and within this hole is a second convex ring. The inner diameter of the second convex ring is smaller than the outer diameter of the thrust bearing, and the lower end face of the thrust bearing abuts against the upper ring surface of the second convex ring. The outer connector is connected to the connecting disc by bolts. This allows for a rotatable connection between the tension-bearing swivel ring and the connecting rod 9, preventing the cable from becoming entangled with the chain.

[0031] A conductive pulley 15 is installed inside the bearing rotating ring to ensure a rotatable communication connection and signal transmission.

[0032] In some embodiments, a tension sensor 16 is also included. One end of the tension sensor 16 is connected to the connecting rod 9, and the other end is connected to the second connecting member 3. The tension sensor 16 is used for weighing. The control board 6 can receive the tension signal fed back by the tension sensor 16 in real time. When the operator presses down or lifts the chain crane integrated control device for a short time, a short-term change in force will occur. At this time, the control board 6 can generate a corresponding lower-level control signal according to the data change, thereby controlling the chain crane to move down or up, which makes the operation more convenient for the operator.

[0033] In some embodiments, a human infrared sensor may also be included, which can sense the infrared radiation of a human body. When someone approaches and makes an upward lifting motion, the sensor sends a signal to the control board 6, thereby controlling the chain crane to move upward. When a downward pressing motion is made, the sensor sends a signal to the control board 6, thereby controlling the chain crane to move downward.

[0034] In some embodiments, a laser sensor switch 17 is also included. The laser sensor switch 17 is disposed on the connecting part 1, specifically inside the mounting housing 10. The mounting housing 10 has a through hole at one end facing the sliding part 4. The detection end of the laser sensor switch 17 is located inside the through hole. The laser sensor switch 17 is disposed facing the sliding part 4 and is connected to the control board 6. Specifically, the setting direction of the laser sensor switch 17 can be parallel to the length direction of the connecting rod 9, so that the laser sensor switch 17 can detect the position on one side of the sliding part 4. The device can only be started when the sliding part 4 is slid when a human hand is detected to be grasping the sliding part 4.

[0035] In some embodiments, the system also includes a speed control knob 18, an emergency stop switch 19, and a display screen 20, all connected to the control board 6. The speed control knob 18, emergency stop switch 19, and display screen 20 are all mounted on the mounting housing 10. The speed control knob 18 can be used for mechanical speed adjustment; for this purpose, mechanical control buttons connected to the control board 6, such as up buttons and down buttons, can also be provided for control. The emergency stop switch 19 is used for emergency stopping. The display screen 20 is used to limit data information.

[0036] In some embodiments, a switching button and a speed control knob 18 may also be included. The switching button can switch the control mode, for example, switching the stepless sliding speed control mode of the sliding part 4 to a fixed speed mode. In the fixed speed mode, the speed can be adjusted by the speed control knob 18, while the up and down sliding of the sliding part 4 only controls the sliding direction.
