Description
Technical Field
[0001] This utility model relates to the field of industrial remote control technology, specifically a wireless remote control for overhead cranes with voice broadcast function. Background Technology
[0002] Overhead cranes generally refer to bridge cranes, gantry cranes, etc., characterized by their ability to vertically lift or horizontally move heavy objects suspended on hooks or other lifting devices within a space. Bridge cranes include a hoisting mechanism and a trolley traveling mechanism. Through the coordinated operation of these mechanisms, heavy objects can be lifted and moved within a defined cubic space. Overhead cranes are primarily controlled wirelessly, eliminating the need for personnel to climb onto the crane for operation, offering a wide field of vision, and providing convenient and quick operation.
[0003] To reduce the occurrence of drops, existing wireless remote controls for overhead cranes with voice broadcast functions are usually equipped with anti-loss ropes. These anti-loss ropes are typically made of nylon or other fibers. However, industrial remote controls are different from those for traditional small household devices. Industrial remote controls are usually heavier, and the fiber ropes are subjected to greater tensile forces, resulting in a shorter lifespan for the anti-loss ropes and a tendency to break. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a wireless remote controller for overhead cranes with voice broadcast function to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wireless remote controller for a crane with voice broadcast function, comprising a remote controller body, a support base fixed to the bottom of the remote controller body, and slots on both sides of the outer surface of the support base, a cover plate connected to the outer surface of the support base, and buckles fixed to both sides of the back of the cover plate; an anti-loosening plate fixed in the middle of the back of the cover plate, a support block connected inside the support base, and anti-loss ropes connected to both sides of the support block, an anti-wear sleeve sleeved on the outside of the anti-loss rope, and an adjustment block connected to the outer surface of the anti-wear sleeve.
[0006] By adopting the above technical solution, the worker puts their hand through the anti-abrasion sleeve, and then slides the adjusting block to adjust the opening size of the anti-abrasion sleeve. This prevents the anti-loss rope and anti-abrasion sleeve from slipping off the worker's arm due to their thin arms. The interference fit between the anti-abrasion sleeve and the adjusting block creates resistance between them. Since the anti-abrasion sleeve is a flexible structure, although there is resistance, the adjusting block can still be slid with force. Wearing the anti-loss rope makes the remote control less likely to slip out of the hand, increasing safety. The anti-loss rope is made of stainless steel, which has advantages such as corrosion resistance, acid and alkali resistance, and long lifespan. Its tensile strength is also much higher than that of traditional fiber ropes. Furthermore, the anti-loss rope is made of multiple strands of fine steel wire, which is highly flexible, disperses stress when bent, and has strong fatigue resistance. It is suitable for high-frequency bending and medium-load scenarios, capable of bearing the weight of the remote control while being flexible enough to avoid impact. The anti-loss rope is designed for easy use; it is wrapped in an anti-abrasion sleeve. The TPU material is elastic, wear-resistant, and can buffer the bending stress of the anti-loss rope. At the same time, the soft TPU anti-abrasion sleeve can prevent the anti-loss rope from chafing the staff's arms. When the anti-loss rope and anti-abrasion sleeve are severely worn after several years of use, the staff can remove the cover plate. Then, the staff can remove the anti-loss rope from the groove on the support block. The staff can then place the new anti-loss rope in the grooves on the top and sides of the support block. Finally, the staff can put the cover plate back in place using the buckle and slot. After the cover plate is put back in place, the anti-loosening plate enters the support base. The anti-loosening plate blocks and limits the top and sides of the support block to prevent the anti-loss rope from loosening and falling out of the groove on the support block. In addition, the support block bears the tension of the anti-loss rope during use, preventing the anti-loss rope from pushing the cover plate open and causing the anti-loss rope to lose its restraint and fall out.
[0007] Furthermore, the support block has grooves on both sides and top, and the anti-loosening plate has an "n" shaped cross section.
[0008] By adopting the above technical solution, after the cover plate is reinstalled, the anti-loosening plate enters the support base. The anti-loosening plate blocks and limits the top and sides of the support block, preventing the anti-loss rope from falling out of the groove on the support block after it loosens. In addition, the anti-loss rope is supported by the support block during use, preventing the anti-loss rope from moving the cover plate and causing the cover plate to open, which would cause the anti-loss rope to lose its limit and fall off.
[0009] Furthermore, the adjusting block is slidably connected to the anti-wear sleeve, and the anti-wear sleeve and the adjusting block are interference-fitted.
[0010] By adopting the above technical solution, the staff can adjust the size of the opening of the anti-abrasion sleeve by sliding the adjustment block, which avoids the phenomenon that the anti-loss rope and anti-abrasion sleeve will slip off the staff's arm due to the staff's thin arms. In addition, the anti-abrasion sleeve and the adjustment block are interference fit, which makes there is resistance between the adjustment block and the anti-abrasion sleeve. Since the anti-abrasion sleeve is a flexible structure, although there is resistance between the adjustment block and the anti-abrasion sleeve, the adjustment block can still be slid by force.
[0011] Furthermore, the cover plate is detachably connected to the support base via buckles and slots, and the anti-loss rope is detachably connected to the support block.
[0012] By adopting the above technical solution, when the anti-loss rope and anti-wear sleeve are worn out after several years of use, the staff can remove them by pressing the cover plate. After that, the staff can remove the anti-loss rope from the groove on the support block.
[0013] Furthermore, the anti-loss rope is made of multiple strands of 304 stainless steel fine wire twisted together.
[0014] By adopting the above technical solutions, the anti-loss rope made of 304 stainless steel has the advantages of corrosion resistance, acid and alkali resistance, and long service life. Its tensile strength is also much higher than that of traditional fiber ropes. It is made of multiple strands of fine steel wire, which is highly flexible, disperses stress when bending, and has strong fatigue resistance. It is suitable for high-frequency bending and medium-load scenarios. It can bear the weight of the remote control body and is relatively soft and easy to bend to avoid affecting its use.
[0015] Furthermore, the abrasion sleeve is made of TPU material, and the abrasion sleeve is fixedly connected to the anti-loss rope through injection molding and overmolding process.
[0016] By adopting the above technical solution, the anti-loss rope is wrapped with an anti-abrasion sleeve. The TPU material has good elasticity and wear resistance and can buffer the bending stress of the anti-loss rope. At the same time, the TPU anti-abrasion sleeve is soft and can prevent the anti-loss rope from chafing the staff's arms.
[0017] Furthermore, a signal antenna is installed on the top of the remote control body, and an emergency stop button, a switch knob, and a speaker are respectively installed on the top of the outer surface of the remote control body. Multiple control buttons are also installed on the outer surface of the remote control body.
[0018] By adopting the above technical solution, the operator can turn on the remote control by rotating the switch knob. The operator can then control the overhead crane using multiple control buttons. Wireless signals are transmitted and received via a signal antenna. During control, a speaker will announce corresponding information. For example, if the operator controls the overhead crane to move eastward using the remote control, the speaker will announce eastward movement when the corresponding control button is pressed. Similarly, when the overhead crane lifts goods, the speaker will announce the lifting of goods when the corresponding control button is pressed. This allows the operator to promptly detect any incorrect button presses during blind operation, improving work efficiency and eliminating the need for the operator to frequently look down to check the remote control. In case of an accident, the operator can press the emergency stop button to bring the overhead crane to an emergency stop.
[0019] Furthermore, a head cover is connected to the top of the signal antenna, and a protective sleeve is fitted over the outside of the signal antenna.
[0020] By adopting the above technical solution, when a staff member walks while holding the remote control body, if the protruding exposed signal antenna collides with an object, the impact force on the signal antenna can be reduced by the headgear and protective cover working together.
[0021] Furthermore, an airbag is fitted onto the outside of the sheath, and the airbag is made of TPU material.
[0022] By adopting the above technical solution, the presence of the airbag improves the cushioning capacity of the signal antenna waist, and the material of the airbag further enhances the cushioning effect, effectively reducing the damage to the signal antenna when it is bumped.
[0023] Furthermore, the headgear is spherical, and both the headgear and the protective cover are made of TPU material.
[0024] By adopting the above technical solutions, the headgear is spherical to achieve the purpose of thickening, and the materials of the headgear and protective cover further improve the cushioning effect, effectively reducing the damage to the signal antenna when it is bumped.
[0025] In summary, the present invention has the following main advantages:
[0026] 1. This utility model features an anti-loss rope, an anti-abrasion sleeve, and an adjusting block. The anti-loss rope is made of 304 stainless steel, which has advantages such as corrosion resistance, acid and alkali resistance, and long service life. Its tensile strength is also much higher than that of traditional fiber ropes. The anti-loss rope is made of multiple strands of fine steel wire, which is highly flexible, disperses stress when bent, and has strong fatigue resistance. It is suitable for high-frequency bending and medium-load scenarios. It can withstand the weight of the remote control body, and is also soft enough to bend without affecting its use. The anti-loss sleeve wraps around the anti-loss rope. The TPU material has good elasticity and wear resistance and can buffer the bending stress of the anti-loss rope. At the same time, the TPU anti-abrasion sleeve is soft and can prevent the anti-loss rope from chafing the operator's arms. The adjusting block allows for easy adjustment of the size of the opening of the anti-loss rope and the anti-abrasion sleeve, preventing the anti-loss rope and the anti-abrasion sleeve from slipping off the operator's arm if the operator's arms are thin. It is strong, corrosion-resistant, soft, comfortable, and easy to use.
[0027] 2. This utility model, through the setting of support base, cover plate, buckle and slot, allows for easy replacement of anti-loss rope and anti-wear sleeve when it is necessary to replace them. Simply remove the cover plate to replace the anti-loss rope and anti-wear sleeve. After replacement, the buckle and slot will lock the cover plate in place, thus completing the replacement operation. It is convenient and quick to replace, and the operation is much simpler than the traditional method of threading a thin line through a thin hole, which is prone to misalignment.
[0028] 3. This utility model, through the setting of support blocks and anti-loosening plates, allows the anti-loss rope to be placed in the grooves on the top and sides of the support block during installation. The anti-loosening plates also cover and limit the top and sides of the support block, preventing the anti-loss rope from falling out of the grooves on the support block after it loosens. During use, the support block bears the tension of the anti-loss rope, preventing the anti-loss rope from pushing open the cover plate and causing it to lose its restraint and fall off. This improves stability and prevents the anti-loss rope from pushing open the cover plate and falling off. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0036] The embodiments of this utility model will be described below based on its overall structure.
[0037] Example 1:
[0038] A wireless remote control for overhead cranes with voice broadcast function, such as Figures 1-4As shown, the device includes a remote control body 1, with a support base 10 fixed to the bottom. The support base 10 has slots 17 on both sides of its outer surface. A cover plate 12 is connected to the outer surface of the support base 10, and the cover plate 12 is detachably connected to the support base 10 via buckles 16 and slots 17. Buckles 16 are fixed to both sides of the back of the cover plate 12. An anti-loosening plate 18 is fixed to the middle of the back of the cover plate 12. A support block 11 is connected inside the support base 10. An anti-loss rope 13 is detachably connected to the support block 11. Grooves are provided on both sides and the top of the support block 11. The anti-loosening plate 18 has an "n"-shaped cross-section. When the device has been used for several years or when the anti-loosening rope 13 and the anti-wear sleeve 14 are severely worn, the operator can remove the cover plate 12 by pressing it down. Afterward, the operator can remove the anti-loosening rope 13 from the support block. The new anti-loss rope 13 is then placed in the grooves on the top and sides of the support block 11 during installation. Finally, the cover plate 12 is reinstalled using the buckle 16 and slot 17. After the cover plate 12 is reinstalled, the anti-loosening plate 18 enters the support base 10, thus blocking and limiting the top and sides of the support block 11 to prevent the anti-loss rope 13 from loosening and falling out of the grooves on the support block 11. Furthermore, the support block 11 bears the tension of the anti-loss rope 13 during use, preventing it from dislodging the cover plate 12 and causing it to lose its restraint and fall out. Anti-loss ropes 13 are connected to both sides of the support block 11. The anti-loss ropes 13 are made of multiple strands of 304 stainless steel wire twisted together. 3. An anti-abrasion sleeve 14 is fitted externally. The anti-abrasion sleeve 14 is made of TPU material and is fixedly connected to the anti-loss rope 13 through injection molding. An adjusting block 15 is connected to the outer surface of the anti-abrasion sleeve 14. The adjusting block 15 is slidably connected to the anti-abrasion sleeve 14, and the anti-abrasion sleeve 14 and the adjusting block 15 are interference-fitted. The worker puts his hand through the anti-abrasion sleeve 14, and then slides the adjusting block 15 to adjust the opening size of the anti-abrasion sleeve 14. This prevents the anti-loss rope 13 and the anti-abrasion sleeve 14 from slipping out of the worker's arm if the worker's arm is thin. The interference fit between the anti-abrasion sleeve 14 and the adjusting block 15 creates resistance between them. Since the anti-abrasion sleeve 14 is a flexible structure, although there is resistance between the adjusting block 15 and the anti-abrasion sleeve 14, the resistance is still maintained. Despite resistance, the adjustment block 15 can still be slidable with force. The anti-loss rope 13 makes it less likely for the remote control body 1 to slip out of the hand and fall, increasing safety. The anti-loss rope 13 is made of 304 stainless steel, which has the advantages of corrosion resistance, acid and alkali resistance, and long service life. Its tensile strength is also much higher than that of traditional fiber ropes. The anti-loss rope 13 is made of multiple strands of fine steel wire, which is highly flexible, disperses stress when bent, and has strong fatigue resistance. It is suitable for high-frequency bending and medium-load scenarios. It can bear the weight of the remote control body 1, and is also soft enough to bend without affecting its use. The anti-loss rope 13 is wrapped by the anti-abrasion sleeve 14. The TPU material is elastic, wear-resistant, and can buffer the bending stress of the anti-loss rope 13. At the same time, the TPU anti-abrasion sleeve 14 is soft and can prevent the anti-loss rope 13 from chafing the operator's arms.
[0039] See Figure 1 and Figure 5 In the above embodiment, a signal antenna 2 is installed on the top of the remote control body 1. An emergency stop button 3, a switch knob 4, and a speaker 5 are respectively installed on the top of the outer surface of the remote control body 1. Multiple control buttons 6 are installed on the outer surface of the remote control body 1. The operator can turn on the remote control body 1 by rotating the switch knob 4. After that, the operator can control the overhead crane through the multiple control buttons 6. The wireless signal is transmitted and received by the signal antenna 2. During the control, the speaker 5 will broadcast the corresponding information. For example, when the operator controls the overhead crane to move eastward through the remote control body 1, the speaker 5 will broadcast the eastward movement when the corresponding control button 6 is pressed. Similarly, when the overhead crane lifts the goods, the speaker 5 will broadcast the goods being lifted when the corresponding control button 6 is pressed. This allows the operator to promptly detect when the operator presses the wrong control button 6 while blindly operating, improving work efficiency and eliminating the need for the operator to frequently look down to check the remote control body 1. In the event of an accident, the operator can press the emergency stop button 3 to stop the overhead crane immediately.
[0040] Example 2:
[0041] Based on the above embodiment one, the following settings are now implemented to facilitate antenna protection.
[0042] See Figure 1 and Figure 5 In the above embodiment, a head cover 7 is connected to the top of the signal antenna 2, and a protective cover 8 is fitted over the outside of the signal antenna 2. When the staff walks with the remote control body 1 in hand, if the exposed signal antenna 2 collides with an object, the head cover 7 and the protective cover 8 work together to reduce the impact force on the signal antenna 2.
[0043] Example 3:
[0044] Based on the above embodiment one, in order to further improve the protection effect, the following settings are now implemented.
[0045] See Figure 1 and Figure 5 In the above embodiment, an airbag 9 is fitted onto the outside of the protective sleeve 8. The airbag 9 is made of TPU material. The head cover 7 is spherical. Both the head cover 7 and the protective sleeve 8 are made of TPU material. The spherical shape of the head cover 7 is for the purpose of thickening. The presence of the airbag 9 improves the cushioning capacity of the waist of the signal antenna 2. The materials of the head cover 7, the protective sleeve 8 and the airbag 9 further improve the cushioning effect and effectively reduce the damage to the signal antenna 2 when it is bumped.
[0046] The implementation principle of this utility model is as follows: First, the worker puts his hand through the anti-abrasion sleeve 14, and then the worker slides the adjusting block 15 to adjust the opening size of the anti-abrasion sleeve 14 to prevent the anti-loss rope 13 and the anti-abrasion sleeve 14 from slipping off the worker's arm due to the worker's thin arm. The anti-abrasion sleeve 14 and the adjusting block 15 are interference fit, so there is resistance between the adjusting block 15 and the anti-abrasion sleeve 14. Since the anti-abrasion sleeve 14 is a flexible structure, although there is resistance between the adjusting block 15 and the anti-abrasion sleeve 14, the adjusting block 15 can still be slid with force.
[0047] The anti-loss rope 13 makes it less likely for the remote control body 1 to slip out of the hand and fall, increasing safety. The anti-loss rope 13 is made of 304 stainless steel, which has the advantages of corrosion resistance, acid and alkali resistance, and long service life. Its tensile strength is also much higher than that of traditional fiber ropes. The anti-loss rope 13 is made of multiple strands of fine steel wire, which is highly flexible, disperses stress when bent, and has strong fatigue resistance. It is suitable for high-frequency bending and medium-load scenarios. It can bear the weight of the remote control body 1, and is also soft enough to bend without affecting its use. The anti-loss rope 13 is wrapped by the anti-abrasion sleeve 14. The TPU material is elastic, wear-resistant and can buffer the bending stress of the anti-loss rope 13. At the same time, the TPU anti-abrasion sleeve 14 is soft and can prevent the anti-loss rope 13 from chafing the operator's arms.
[0048] When a staff member walks while holding the remote control body 1, if the protruding and exposed signal antenna 2 collides with an object, the headgear 7 and protective cover 8 work together to reduce the impact force on the signal antenna 2. The headgear 7 is spherical to achieve the purpose of thickening, and the presence of airbag 9 improves the cushioning capacity of the signal antenna 2 at the waist. The materials of the headgear 7, protective cover 8 and airbag 9 further improve the cushioning effect and effectively reduce the damage to the signal antenna 2 when it is bumped.
[0049] The operator can turn on the remote control body 1 by rotating the switch knob 4. After that, the operator can control the overhead crane through multiple control buttons 6. The wireless signal is transmitted and received by the signal antenna 2. During the control, the speaker 5 will broadcast the corresponding information. For example, when the operator controls the overhead crane to move eastward through the remote control body 1, the speaker 5 will broadcast the eastward movement when the corresponding control button 6 is pressed. Similarly, when the overhead crane lifts goods, the speaker 5 will broadcast the goods being lifted when the corresponding control button 6 is pressed. This allows the operator to promptly detect if they accidentally press the wrong control button 6 while blindly operating the crane, improving work efficiency and eliminating the need for the operator to frequently look down to check the remote control body 1. In case of an accident, the operator can press the emergency stop button 3 to stop the overhead crane immediately.
[0050] When the anti-loss rope 13 and anti-wear sleeve 14 are severely worn after several years of use, the staff can remove the cover plate 12 by snapping it open. Then, the staff can remove the anti-loss rope 13 from the groove on the support block 11. The staff then places the new anti-loss rope 13 in the grooves on the top and sides of the support block 11 during installation. Finally, the staff uses the buckle 16 and the slot 17 to reinstall the cover plate 12. After the cover plate 12 is reinstalled, the anti-loosening plate 18 enters the support base 10. The anti-loosening plate 18 blocks and limits the top and sides of the support block 11 to prevent the anti-loss rope 13 from loosening and falling out of the groove on the support block 11. In addition, the anti-loss rope 13 is supported by the support block 11 during use, which prevents the anti-loss rope 13 from pushing the cover plate 12 open and causing the anti-loss rope 13 to lose its restraint and fall out.
[0051] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
