Description

Technical Field

[0001] This utility model relates to the field of crane end beams, and in particular to a soft starter device for crane end beams. Background Technology

[0002] The crane end beam soft starter is a device used to control the starting current and torque of the motor when starting and stopping an electric crane. The main function of this device is to achieve smooth starting and stopping of the motor, thereby reducing mechanical shock and improving the operational safety and reliability of the equipment.

[0003] The soft starter for the overhead crane end beam reduces the impact force during startup by controlling the starting process of the motor, preventing sudden mechanical vibrations during equipment startup, thus protecting the equipment and goods. The soft starter can effectively control the current of the motor during startup, avoiding the impact of instantaneous large current on the power grid and motor, improving the stability of the power grid and the service life of the motor, and enhancing the safety of equipment operation.

[0004] When controlling the operation of the crane end beam, a remote control is usually installed at the bottom of the crane end beam and connected to the crane end beam via a power cord. However, if the remote control is directly connected via a power cord, the power cord may break or the connection may become loose when the remote control is subjected to tension. Furthermore, it is not convenient to adjust the height of the remote control according to the usage requirements. Utility Model Content

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] This utility model provides, for example Figure 1-5 The image shows a soft starter for a crane end beam.

[0045] Example 1

[0046] The device includes a crossbeam 1, a crane-end body 2, a remote controller 3, a connecting cable 4, a connecting strap 5, and a storage assembly 6. The crane-end body 2 is connected to the top of the crossbeam 1, and the remote controller 3 is located at the bottom of the crane-end body 2. The connecting cable 4 is electrically connected to the remote controller 3 and the crane-end body 2. When the remote controller 3 sends a control signal to the crane-end body 2 through the connecting cable 4, the voltage and current input to the motor are adjusted by the controller and voltage regulator to gradually increase the speed of the motor, thereby achieving soft start of the crane-end body 2. This is existing technology and will not be described in detail here. The ends of the connecting strap 5 are connected to the remote controller 3 and the crane-end body 2 respectively, and the length of the connecting strap 5 is less than the length of the connecting cable 4. Therefore, when the remote controller 3 is subjected to tension, the connecting strap 5 is subjected to a tensile force, so that the connecting cable 4 is not subjected to a tensile force. The storage assembly 6 is installed on the top of the remote controller 3. The storage assembly 6 is used to store the connecting cable 4 and the connecting strap 5, thereby changing the hanging height of the remote controller 3.

[0047] Furthermore, the storage assembly 6 includes a storage housing 61, a partition 62, and a storage and unfolding assembly 63. The storage housing 61 is fixedly installed on the top of the remote control 3. The top of the storage housing 61 has a wire inlet hole. The partition 62 is fixedly connected to the inside of the storage housing 61. The partition 62 is used to divide the inside of the storage housing 61 into two chambers, so that the connecting wire 4 and the connecting strap 5 are stored in different chambers in the storage housing 61. The storage and unfolding assembly 63 is disposed on the top of the inner cavity of the storage housing 61.

[0048] Furthermore, the take-up and release assembly 63 includes a driven roller 631, a drive shaft 632, and a drive roller 633. The driven roller 631 is rotatably disposed at the top of the inner cavity of the storage housing 61. The outer wall of the drive shaft 632 is rotatably connected to the storage housing 61. The drive roller 633 is fixedly sleeved on the outside of the drive shaft 632. The drive shaft 632 drives the drive roller 633 to rotate, so that the driven roller 631 and the drive roller 633 cooperate to take up or release the connecting line 4 and the connecting belt 5.

[0049] Furthermore, the retractable assembly 63 also includes a fixed shaft 634, a silicone sleeve, and a locking assembly 64. The fixed shaft 634 is fixedly connected to the inside of the storage housing 61. The driven roller 631 is rotatably sleeved on the outside of the fixed shaft 634. The silicone sleeve is sleeved on the outside of the driven roller 631 and the drive roller 633 respectively. The width of the connecting strip 5 is greater than the width of the connecting line 4. Under the action of the silicone sleeve, the friction between the connecting strip 5 and the driven roller 631 and the drive roller 633 can be increased, thereby ensuring the stability of its storage. The locking assembly 64 is set at one end of the outer wall of the drive shaft 632.

[0050] Example 2

[0051] Based on Embodiment 1, the locking assembly 64 includes a connecting cap 641, a positioning rod 642, a fixing collar 643, a slider 644, and a connecting block 645. The connecting cap 641 is slidably sleeved on the outside of the drive shaft 632. One end of the positioning rod 642 is fixedly connected to the connecting cap 641. A positioning groove matching the positioning rod 642 is provided on one side of the housing 61. When the positioning rod 642 is engaged with the positioning groove, the positioning rod 642 can limit the drive shaft 632 through the connecting cap 641, thereby ensuring the stability of the positioning of the driven roller 631 and the drive roller 633 on the connecting belt 5. The fixing collar 643 is fixedly sleeved on one end of the inner cavity of the connecting cap 641. The slider 644 is fixedly connected to the inside of the fixing collar 643. A groove matching the slider 644 is provided on one end of the outer wall of the drive shaft 632. The slider 644 can keep the connecting cap 641 and the drive shaft 632 rotating synchronously. The connecting block 645 is fixedly connected to the end of the drive shaft 632.

[0052] Furthermore, the locking assembly 64 also includes a limiting block 646 and a limiting spring 647. The side of the connecting block 645 has a mounting hole that matches the limiting block 646. One end of the limiting block 646 is arc-shaped. The inner wall of the connecting cap 641 has a limiting groove that matches the limiting block 646. Figure 5 As shown, the limiting block 646 engages with limiting positions at different locations. The connecting cap 641 drives the positioning rod 642 to be in a separated or engaged state with the positioning groove on one side of the housing 61. The limiting spring 647 is slidably sleeved inside the mounting hole. The end of the limiting spring 647 is pressed against the limiting block 646. The limiting spring 647 can ensure the stability of the engagement between the limiting block 646 and the limiting groove. Furthermore, by manually applying a force along the axis of the drive shaft 632 to the connecting cap 641, the limiting block 646 can be slidably separated from the limiting groove on the connecting cap 641.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
