Description

Technical Field

[0001] The present invention belongs to the technical field of crane control cabinets, and more specifically, relates to a crane control cabinet structure. The present invention also relates to a control method for the crane control cabinet structure. Background Art

[0002] A crane is a common name for bridge cranes, such as overhead cranes and overhead cranes. There are two basic types of crane drive systems: centralized drive, where a single electric motor drives a long drive shaft, driving two driving wheels; and separate drive, where each driving wheel is driven by a separate electric motor. Crane operation primarily utilizes a control cabinet, which traditionally houses control electrical components and connecting wiring to control their operation. A control cabinet typically consists of a cabinet body (a housing) housing various control electrical components and their connecting wiring. These components are typically organized into functional modules and mounted on a base within the cabinet body.

[0003] Conventional control cabinets contain numerous electrical components, some with high heat rates and some with low heat rates, and these components are located at different heights. Each component generates significant heat during operation, and since these components are fixed in position, high-heat-rate components can affect the lower-heat-rate components, potentially damaging them or affecting their normal operating performance, impacting the reliability and safety of the control cabinet.

[0004] Patent application CN108718492A, a state-of-the-art technology, describes a control cabinet comprising an outer frame, a slide plate, and a grille cover. The control cabinet has a vent on its side, and the outer frame is fixed to the outside of the vent. The outer frame has two internal grooves with circular holes at the upper and lower ends. Springs are fixed within the circular holes, and spring beads are fixed to the springs. The slide plate is mounted within the outer frame's slides and can slide up and down. The slide plate is provided with upper and lower frames of equal size, each containing dustproof cotton of varying thicknesses. Hemispherical grooves corresponding to the spring beads are provided on the upper and lower ends of the slide plate. A handle is fixed to the right side of the slide plate. The grille cover is mounted on the outside of the outer frame and fixed to the control cabinet via screws. The outer frame's right slide plate and the grille cover each have slots corresponding to the handle. The aforementioned patent uses a handle to control the slide plate's movement, thereby switching between different thicknesses of dustproof cotton for use outside the vent to achieve the desired dustproofing effect in different weather conditions.

By setting the shaft sleeve 47 and the rotating plate, the rotating plate can rotate on the shaft sleeve 47, so that the pull rod 41 can rotate in the third slot, thereby driving the first clamping block 45 to be clamped on the mounting plate 8, which is convenient for workers to carry out the work of winding the wires. The upper surface of the rotating plate is fixedly connected to a telescopic rod 46, and the other end of the telescopic rod 46 is fixedly connected to the pull rod 41.

When the wire is ready, the first handle 42 is rotated to the appropriate position, and the pull rod 41 moves downward due to the rebound force of the first spring 48, thereby driving the soft pad 43 to squeeze the wire, so that the wire is fixed.

[0007] However, the prior art does not involve the technical problems and technical solutions of the present application. Summary of the Invention

The clamping disc includes two semicircular clamping disc assemblies, one side of the two clamping disc assemblies is movably connected, and the other end of the two clamping disc assemblies is fixedly connected by bolts.

[0012] A servo motor 2 is fixedly mounted on the upper surface of the clamping disc, and the output shaft of the servo motor 2 passes through the clamping disc and is transmission-connected to the driving wheel located on the lower surface of the clamping disc. A plurality of driven wheels are evenly mounted on the lower surface of the clamping disc, and the plurality of driven wheels and the driving wheel are driven by a transmission belt. Each driven wheel is transmission-connected to a bevel gear 1 on the upper surface of the clamping disc through a rotating shaft, and the bevel gear 1 is meshed with the bevel gear 2. A threaded rod is fixedly mounted on the bevel gear 2, and a threaded sleeve is connected to the external thread of the threaded rod, and the threaded sleeve is rotationally connected to a fixed block fixedly mounted on the wire mounting plate.

[0013] The wire installation plate includes four wire installation plate assemblies, which are spliced ​​into a square structure. The adjacent sides of the wire installation plate assemblies are respectively provided with balancing grooves and balancing blocks, and the balancing grooves and balancing blocks are movably connected to each other.

[0014] The top inner wall and the bottom inner wall of the cabinet are respectively fixedly installed with sliding sleeves, the upper part of the screw rod is movably sleeved in the sliding sleeve of the top inner wall, and the lower part of the screw rod is movably sleeved in the sliding sleeve of the bottom inner wall. The top inner wall and the bottom inner wall of the cabinet are respectively fixedly installed with cylinder 1, the piston rod of cylinder 1 is connected to the sleeve slidingly connected to the corresponding sliding sleeve, and a lifting plate is fixedly installed on the outer circumference of the sleeve, and a plurality of winding wheels are installed on the lifting plate.

[0018] The present invention also relates to a method for controlling a crane control cabinet structure with simple steps, which effectively solves the problem that the control cabinet cannot separate electrical components with high and low heat rates to avoid mutual influence between the electrical components, and simultaneously solves the problem that wire entanglement cannot be avoided when different electrical components are separated from each other, thereby avoiding affecting the normal working performance of the control cabinet and improving the reliability and safety of the control cabinet. The control steps of the control method for the crane control cabinet structure are as follows:

[0019] S1. When the electrical components inside the cabinet need to dissipate heat, the servo motor is driven to rotate, which drives the lead screw to rotate. The lead screw cooperates with the two threaded sleeves to drive the two threaded sleeves to rotate in opposite directions. The distance between the wire mounting plates of each wire mounting plate assembly is adjusted. Electrical components of different heights are installed on different wire mounting plates in the same group. The different wire mounting plates are separated to prevent electrical components with high heat rates from affecting electrical components with low heat rates, causing damage and interfering with normal operation.

[0020] S2. Start servo motor 2 to drive the driving wheel to rotate, and the driving wheel drives multiple driven wheels to rotate through the transmission belt. The multiple driven wheels respectively drive the corresponding bevel gear 1 to rotate, and each bevel gear 1 drives the corresponding bevel gear 2 to rotate, and each bevel gear 2 drives the corresponding threaded rod to rotate, and each threaded rod drives the corresponding threaded sleeve to move, and then pushes the corresponding wire mounting plate to move outward through the corresponding fixed block. Different wire mounting plates of the same wire mounting plate assembly are separated from each other, and there is a certain distance between the electrical components on the other side, to avoid the different wire mounting plates of the same wire mounting plate assembly being separated from each other, and mutual influence between the electrical components on the other side causing damage and interference with normal work.

[0021] When the wire mounting plate needs to be adjusted up and down, the cylinder is driven to push the sleeve to slide up and down on the sliding sleeve, thereby driving the lifting plate to move up and down, and then driving the winding wheel to move up and down. There is an electric wire wound around the winding wheel. The setting of the winding wheel ensures that the wire on the wire mounting plate is in a taut state and is not easy to be entangled; or in a loose state to avoid jamming.

[0022] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:

[0023] The driving control cabinet structure described in the present invention has a servo motor 1 fixedly installed on the top of the cabinet when the structure is set. The servo motor 1 can realize start and stop, speed and rotation direction control through the control component, and the output shaft of the servo motor 1 is connected to the screw rod, one end of the screw rod extends into the cabinet and is rotatably connected to the bottom of the cabinet, that is, the screw rod extends from the inner wall of the top of the cabinet to the inner wall of the bottom, and multiple groups of threaded kits are connected on the screw rod, each group of threaded kits includes two threaded sleeves, and the two threaded sleeves of each group of threaded kits are installed with opposite threads of the screw rod, and a limiting groove is provided on the threaded sleeve, and a clamping disk is clamped at the position of the limiting groove, and a wire mounting plate is respectively connected to the circumference of each clamping disk. In this way, when the screw rod rotates, the threaded sleeve is driven to move up and down relative to the screw rod, that is, the clamping disk is moved up and down, thereby driving the wire mounting plate to move up and down in the cabinet. The size of the wire mounting plate is slightly smaller than the cabinet, ensuring that it can only move up and down but not rotate in the cabinet. Each wire mounting plate includes multiple wire mounting plate assemblies, each of which has an electrical component mounted thereon. Wire mounting plate assemblies at different heights are mounted with electrical components of different heights. Alternatively, some wire mounting plate assemblies on the same wire mounting plate are mounted with electrical components of the same heat generation rate, while some wire mounting plate assemblies on the same wire mounting plate are mounted with electrical components of a high heat generation rate, while some wire mounting plate assemblies on the same wire mounting plate are mounted with electrical components of a low heat generation rate. In this way, when electrical components are placed in a cabinet, they can be categorized. On the one hand, based on height, components requiring a higher height can be placed on the upper wire mounting plate, while components requiring a lower height can be placed on the lower wire mounting plate. On the other hand, based on heat generation rate, components requiring the same heat generation rate can be placed on some wire mounting plate assemblies on the same wire mounting plate. In this way, by controlling the rotation of the screw rod in different directions, the distance between the two wire mounting plates can be adjusted. When the distance is increased, the mutual influence of electrical components with different heating rates on different wire mounting plates can be reduced. That is, there is a certain distance between the electrical components on each wire mounting plate. The electrical components with high heating rates will not cause damage or influence on the electrical components with low heating rates. The electrical components can be effectively protected to avoid damage or influence on working performance and improve stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following describes the embodiments with reference to the accompanying drawings to further explain in detail the specific embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships between the various components involved, the functions and working principles of the various components.

[0033] As attached Figure 1As shown, the present invention is a driving control cabinet structure, including a cabinet 1, a servo motor 11 is fixedly installed on the top of the cabinet 1, the output shaft of the servo motor 11 is connected to a screw rod 13, one end of the screw rod 13 extends into the cabinet 1 and is rotatably connected to the bottom of the cabinet 1, and a plurality of sets of threaded kits are sleeved on the screw rod 13, each set of threaded kits includes two threaded sleeves 14, and the thread rotation directions of the screws installed by the two threaded sleeves of each set of threaded kits are opposite, and a limiting groove is provided on the threaded sleeve 14, and a clamping disk 15 is clamped at the position of the limiting groove, and a wire mounting plate 16 is respectively connected to the circumference of each clamping disk 15, each wire mounting plate 16 includes a plurality of wire mounting plate assemblies, and each wire mounting plate assembly is respectively installed with an electrical component; electrical components of different heights are respectively installed on wire mounting plate assemblies of different heights, and some wire mounting plate assemblies of the same wire mounting plate 16 have electrical components with the same heat generation rate, or some wire mounting plate assemblies of the same wire mounting plate 16 are installed with electrical components with a high heat generation rate, and some wire mounting plate assemblies of the same wire mounting plate 16 are installed with electrical components with a low heat generation rate. The above structure proposes an improved technical solution to address the deficiencies in the existing technology. When the structure is set up, a servo motor 11 is fixedly installed on the top of the cabinet 1. The servo motor 11 can realize start and stop, speed and rotation direction control through the control component, and the output shaft of the servo motor 11 is connected to the screw rod 13. One end of the screw rod 13 extends into the cabinet 1 and is rotatably connected to the bottom of the cabinet 1, that is, the screw rod extends from the inner wall of the top of the cabinet to the inner wall of the bottom. Multiple sets of threaded kits are installed on the screw rod 13, each set of threaded kits includes two threaded sleeves 14, and the two threaded sleeves of each set of threaded kits have opposite thread rotation directions. A limiting groove is provided on the threaded sleeve 14, and a clamping disk 15 is clamped at the position of the limiting groove. A wire mounting plate 16 is respectively connected to the circumference of each clamping disk 15. In this way, when the screw rod rotates, the threaded sleeve is driven to move up and down relative to the screw rod, that is, the clamping disk 15 is moved up and down, thereby driving the wire mounting plate 16 to move up and down in the cabinet. The size of the wire mounting plate 16 is slightly smaller than the cabinet, ensuring that it can only move up and down in the cabinet but not rotate. Each wire mounting plate 16 includes a plurality of wire mounting plate assemblies, each of which is equipped with an electrical component. Wire mounting plate assemblies of different heights are equipped with electrical components of different heights. Some wire mounting plate assemblies on the same wire mounting plate 16 have electrical components with the same heating rate. Alternatively, some wire mounting plate assemblies on the same wire mounting plate 16 have electrical components with high heating rates, while some wire mounting plate assemblies on the same wire mounting plate 16 have electrical components with low heating rates. In this way, when electrical components are arranged in a cabinet, they can be classified. On the one hand, based on height classification, electrical components that require a higher height can be placed on the upper wire mounting plate, while components that require a lower height can be placed on the lower wire mounting plate. On the other hand, based on heating rate classification, electrical components with the same heating rate can be placed on some wire mounting plate assemblies on the same wire mounting plate 16.In this way, by controlling the rotation of the screw rod 13 in different directions, the distance between the two wire mounting plates can be adjusted. When the distance is increased, the mutual influence of electrical components with different heating rates on different wire mounting plates can be reduced, that is, there is a certain distance between the electrical components on each wire mounting plate. The electrical components with high heating rates will not cause damage or influence on the electrical components with low heating rates, which can effectively protect the electrical components, avoid damage or influence on working performance, and improve stability.

[0034] The clamping disc 15 is provided with a clamping strip around its periphery. The clamping disc 15 is clamped into the limiting groove of the threaded sleeve 14 via the clamping strip to achieve connection with the threaded sleeve 14. The clamping disc 15 comprises two semicircular clamping disc assemblies, one end of which is movably connected to the other end of which is fixedly connected by bolts. The above structure positions the clamping disc 15 in the limiting groove via the clamping strip to achieve positioning of the clamping disc, and then fixes the clamping disc via bolts. In this way, the clamping disc is connected to the threaded sleeve to ensure a reliable connection and easy disassembly. After disassembly, the electrical components on the wire mounting plate 16 can be easily repaired or replaced, and it is not necessary to remove all electrical components when a component has a problem, which makes operation more convenient.

[0035] A servo motor 2 151 is fixedly mounted on the upper surface of the clamping disc 15. The output shaft of the servo motor 2 151 passes through the clamping disc 15 and is transmission-connected to a driving wheel 152 located on the lower surface of the clamping disc 15. A plurality of driven wheels 154 are evenly mounted on the lower surface of the clamping disc 15. The plurality of driven wheels 154 and the driving wheel 152 are transmitted via a transmission belt 153. Each driven wheel 154 is transmission-connected to a bevel gear 1 156 on the upper surface of the clamping disc 15 through a rotating shaft. The bevel gear 1 156 is meshed with the bevel gear 2 157. A threaded rod 158 is fixedly mounted on the bevel gear 2 157. The threaded rod 158 is externally threaded and fitted with a threaded sleeve 155. The threaded sleeve 155 is rotationally connected to a fixed block 161 fixedly mounted on the wire mounting plate 16. The above structure starts the servo motor 2 151 to drive the driving wheel 152 to rotate, and the driving wheel 152 drives multiple driven wheels 154 to rotate through the transmission belt 153. The multiple driven wheels 154 respectively drive the bevel gear 1 156 to rotate, the bevel gear 1 156 drives the bevel gear 2 157 to rotate, the bevel gear 2 157 drives the threaded rod 158 to rotate, and the threaded rod 158 drives the threaded sleeve 155 to move, and then pushes the wire mounting plate 16 outward through the fixed block 161, that is, the distance between different wire mounting plate assemblies of the same wire mounting plate 16 is increased, and the electrical components with high heat generation rate on different wire mounting plate assemblies of the same wire mounting plate 16 will not cause damage or influence on the electrical components with low heat generation rate, thereby effectively protecting the electrical components and improving the working stability and service life of the electrical components.

[0036] The wire mounting plate 16 comprises four wire mounting plate assemblies assembled into a square structure. Adjacent sides of the wire mounting plate assemblies are provided with balancing slots 164 and balancing weights 165, respectively. These slots 164 and weights 165 are movably engaged and connected. This structure, through the provision of balancing slots 164 and weights 165, ensures a secure connection between the wire mounting plate 16 both when it is moving and when it is stationary, and also ensures reliable movement when the distance between the different wire mounting plate assemblies of the wire mounting plate 16 is adjusted.

[0037] The top inner wall and bottom inner wall of the cabinet 1 are fixedly mounted with a sleeve 12, respectively. The upper portion of the screw rod 13 is movably mounted within the sleeve 12 on the top inner wall, while the lower portion of the screw rod 13 is movably mounted within the sleeve 12 on the bottom inner wall. A cylinder 181 is fixedly mounted on the top inner wall and the bottom inner wall of the cabinet 1, respectively. The piston rod of the cylinder 181 is connected to a sleeve 18 slidably connected to the corresponding sleeve 12. A lifting plate 182 is fixedly mounted on the outer circumference of the sleeve 18, and a plurality of winding reels 183 are mounted on the lifting plate 182. With the above structure, when the wire mounting plate 16 needs to be adjusted up and down, the cylinder 181 is driven to push the sleeve 18 to slide up and down on the sleeve 12, thereby driving the lifting plate 182 up and down, and further driving the winding reels 183 up and down. Wires are wound around the winding reels 183. The arrangement of the winding reels 183 ensures that the wires on the wire mounting plate 16 are in a taut state, which is not easy to get tangled, or in a loose state, which prevents them from getting stuck. That is to say, the distance between the lifting plate 182 and the wire mounting plate 16 can be adjusted according to actual needs, so that tension is achieved when the distance is far and relaxation is achieved when the distance is close, thereby meeting actual needs.

[0038] Each wire mounting plate assembly of the wire mounting plate 16 is provided with a limit wheel 163 at the edge; limit wheels 163 are connected to the corresponding wire mounting plate assembly via springs 162. This structure, through the provision of limit wheels 163, allows the wires to be arranged inward from the edge of the wire mounting plate 16, creating a more neat and orderly arrangement, while also leaving more space for electrical components. The provision of springs 162 also ensures that limit wheels 163 have a certain amount of elasticity, ensuring the safety of the device when the wire mounting plate 16 moves up and down or separates.

[0039] The bottom of the lifting plate 182 is movably connected to an inclined cylinder 2 187, and the end of the piston rod of the cylinder 2 187 is movably connected to the winding wheel 183, and one end of the winding wheel 183 is movably connected to the lifting plate 182. With the above structure, the second cylinder 187 is activated to push the winding wheel 183 to move a certain angle, thereby facilitating the cooperation with the limiting wheel 163 for winding different types of wires, thereby expanding the scope of application and avoiding the inconvenience caused by too limited a scope of use.

[0040] The top inner wall and the bottom inner wall of the cabinet 1 are respectively fixedly mounted with guide rods 184, each guide rod 184 passes through the corresponding lifting plate 182 and is connected to the corresponding limit block 185. A plurality of limit posts 186 are fixedly mounted on the outer circumference of each sliding sleeve 12, and the limit posts 186 are plug-connected with the limit holes provided at the bottom of the sleeve 18. The above structure, through the provision of the guide rods 184, can play a reliable guiding and balancing role, and through the provision of the limit blocks 185, can play a good limiting role to prevent the lifting plate 182 from falling off. At the same time, through the provision of the limit posts 186 and the limit holes, can play a good limiting role to prevent the lifting plate 182 from falling off.

[0041] The present invention also relates to a method for controlling a crane control cabinet structure with simple steps, which effectively solves the problem that the control cabinet cannot separate electrical components with high and low heat rates to avoid mutual influence between the electrical components, and simultaneously solves the problem that wire entanglement cannot be avoided when different electrical components are separated from each other, thereby avoiding affecting the normal working performance of the control cabinet and improving the reliability and safety of the control cabinet. The control steps of the control method for the crane control cabinet structure are as follows:

[0042] When the electrical components inside cabinet 1 need to be cooled, servo motor 11 is driven to rotate, which drives screw 13 to rotate. Screw 13 cooperates with two threaded sleeves 14 to drive the two threaded sleeves 14 to rotate in opposite directions. The distance between the wire mounting plates 16 of each wire mounting plate assembly is adjusted. Electrical components of different heights are installed on different wire mounting plates 16 in the same group. The different wire mounting plates 16 are separated to prevent electrical components with high heat rates from affecting electrical components with low heat rates, causing damage and interfering with normal operation.

[0043] S2. Start the servo motor 2 151 to drive the driving wheel 152 to rotate. The driving wheel 152 drives multiple driven wheels 154 to rotate through the transmission belt 153. The multiple driven wheels 154 respectively drive the corresponding bevel gear 1 156 to rotate. Each bevel gear 1 156 drives the corresponding bevel gear 2 157 to rotate. Each bevel gear 2 157 drives the corresponding threaded rod 158 to rotate. Each threaded rod 158 drives the corresponding threaded sleeve 155 to move, and then pushes the corresponding wire mounting plate 16 to move outward through the corresponding fixed block 161. Different wire mounting plates 16 of the same wire mounting plate assembly are separated from each other. There is a certain distance between the electrical components on the other side, so as to avoid the different wire mounting plates 16 of the same wire mounting plate assembly being separated from each other and affecting each other to cause damage and interfere with normal operation.

[0044] When the wire mounting plate 16 needs to be adjusted up and down, the cylinder 181 is driven to push the sleeve 18 to slide up and down on the sliding sleeve 12, thereby driving the lifting plate 182 to move up and down, and then driving the winding wheel 183 to move up and down. There is an electric wire wound around the winding wheel 183. The setting of the winding wheel 183 ensures that the wires on the wire mounting plate 16 are in a taut state and are not easily entangled; or in a loose state to avoid jamming.

[0045] The driving control cabinet structure and control method described in the present invention are as follows: when the structure is set, a servo motor 11 is fixedly installed on the top of the cabinet 1. The servo motor 11 can realize start and stop, speed and rotation direction control through the control component, and the output shaft of the servo motor 11 is connected to the screw rod 13. One end of the screw rod 13 extends into the cabinet 1 and is rotatably connected to the bottom of the cabinet 1, that is, the screw rod extends from the inner wall of the top of the cabinet to the inner wall of the bottom, and multiple groups of threaded kits are connected on the screw rod 13, each group of threaded kits includes two threaded sleeves 14, and the two threaded sleeves of each group of threaded kits have opposite thread rotation directions of the screw rods installed. A limiting groove is provided on the threaded sleeve 14, and a clamping disk 15 is clamped at the position of the limiting groove. A wire mounting plate 16 is respectively connected to the circumference of each clamping disk 15. In this way, when the screw rod rotates, the threaded sleeve is driven to move up and down relative to the screw rod, that is, the clamping disk 15 is moved up and down, thereby driving the wire mounting plate 16 to move up and down in the cabinet. The size of the wire mounting plate 16 is slightly smaller than the cabinet, ensuring that it can only move up and down in the cabinet but not rotate. Each wire mounting plate 16 includes a plurality of wire mounting plate assemblies, each of which is equipped with an electrical component. Wire mounting plate assemblies of different heights are equipped with electrical components of different heights. Some wire mounting plate assemblies on the same wire mounting plate 16 have electrical components with the same heating rate. Alternatively, some wire mounting plate assemblies on the same wire mounting plate 16 have electrical components with high heating rates, while some wire mounting plate assemblies on the same wire mounting plate 16 have electrical components with low heating rates. In this way, when electrical components are arranged in a cabinet, they can be classified. On the one hand, based on height classification, electrical components that require a higher height can be placed on the upper wire mounting plate, while components that require a lower height can be placed on the lower wire mounting plate. On the other hand, based on heating rate classification, electrical components with the same heating rate can be placed on some wire mounting plate assemblies on the same wire mounting plate 16. In this way, by controlling the rotation of the screw rod 13 in different directions, the distance between the two wire mounting plates can be adjusted. When the distance is increased, the mutual influence of electrical components with different heating rates on different wire mounting plates can be reduced, that is, there is a certain distance between the electrical components on each wire mounting plate. The electrical components with high heating rates will not cause damage or influence on the electrical components with low heating rates, which can effectively protect the electrical components, avoid damage or influence on working performance, and improve stability.

[0046] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
