Description

Technical Field

[0001] This invention relates to a power supply and water supply device, and more particularly to a linear track combined power supply and water supply device with start-up protection function. Background Technology

[0002] Many large outdoor track-mounted mobile machinery and equipment require cables to provide power, remote control, and network communication during operation.

[0003] Traditional power supply methods generally include drums and reels. These methods have the following drawbacks: 1. Due to their self-powered drive, they can be out of sync with the trolley, leading to cables that are either too loose or too tight; 2. They place high demands on the cables, especially three-in-one cables, which are expensive; 3. Due to their winding mechanism, the cables are prone to twisting during operation, and the twisting angle increases with the number of turns, causing the cable to form a spiral shape. This phenomenon is a structural defect; 4. The cables have a short lifespan.

[0004] Based on this, the improved cable conveying device does not require power drive and is driven by the main equipment, overcoming the problems of cables being too loose or too tight. For example, Chinese patent CN218754146U discloses a cable conveying device in which the lifting equipment is connected to the conveying component through a traction frame. When the lifting equipment moves, it can drive the conveying component to move along the guide rail through the traction frame, so that the cable conveying device can maintain the synchronization of movement with the lifting equipment. Moreover, the power for the conveying component to move on the guide rail comes from the movement of the lifting equipment, so there is no need to configure an additional power source, which greatly saves costs.

[0005] However, when the main equipment (lifting equipment) drives the trolley assembly to reciprocate along the straight track via the traction frame, the speed of the main equipment increases from zero at the instant of movement, and the instantaneous acceleration is very large. In addition, the mass of the trolley assembly and other components is very large, which causes the conveyor belt to bear huge stress at the instant of the main equipment starting, which can easily lead to a decline in the performance of the conveyor belt.

[0006] Therefore, researching a linear track combined with power and water supply device that can protect the conveyor belt at the moment the main unit of the equipment starts up has become an urgent technical problem to be solved in this field. Summary of the Invention

[0060] A traction frame, one end of which is connected to the trolley assembly, and the other end is connected to the equipment main body through a starting protection module.

[0061] Furthermore, the trolley assembly includes a conveyor belt, a pulley, a trolley, and a number of wheels. The trolley is supported on the horizontally arranged linear track by the pulleys fixed at both ends.

[0064] The tensioning device is fixedly installed at the symmetrical midpoint position of the linear track.

[0065] Beneficial effects:

[0066] (1) At the moment the main unit starts, the active component and the passive component undergo relative displacement; when the main unit is running smoothly, the active component and the passive component remain relatively fixed. Therefore, at the moment the main unit starts, the active component and the passive component undergo relative displacement, resulting in a slight relative displacement between the main unit and the linear track conveyor, which are rigidly connected to the active and passive components respectively. Consequently, within the same time frame, the distance the traction frame moves is shorter than the distance the main unit moves, and the speed and acceleration of the traction frame decrease at the moment of startup.

[0067] (2) Through the interaction of the protective teeth and the mating teeth, during the retraction of the protective teeth at the moment the main unit starts, the protective teeth and the mating teeth slide laterally, resulting in relative displacement between the active and passive components. Therefore, during the start-up period, the distance the traction frame moves is shorter than the distance the main unit moves, and the speed and acceleration of the traction frame at the moment of start-up exhibit start-up attenuation.

[0068] (3) The linear track combined power supply and water supply device with start-up protection function of the present invention has an active component that is easy to assemble and replace easily damaged parts such as elastic elements, tooth bodies or guide columns through modular assembly. At the same time, the smallest replacement unit of the active component is the elastic element, tooth body or guide column, which does not require the whole component to be replaced due to the damage of a certain part. This is conducive to modular production, purchasing and spare parts, and greatly saves costs.

[0069] (4) By rigidly connecting different passive components to the traction frame, when the main unit of the equipment starts instantaneously, the vertical movement distance of the protective teeth is ensured to be within the ideal limit range. This avoids the protective teeth from disengaging from the mating teeth due to complete retraction, and also avoids the speed and acceleration of the traction frame from being too slow due to the small relative displacement between the active and passive components. Ultimately, this allows the start-up protection module to adapt to more working conditions.

[0070] (5) The linear track combined power and water supply device with start-up protection function of the present invention can be used to switch between different operating conditions of a set of equipment. During the switching process, the long slider remains in the track groove, and it is not necessary to completely disengage the active component from the first connecting part. It is only necessary to push the active component back and forth. Thus, it is not necessary to drag the active component throughout the switching process, saving time and effort. At the same time, the "convex" shaped track groove restricts the degrees of freedom of the active component in the up, down, forward, and backward directions. Attached Figure Description

Detailed Implementation

[0085] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0086] like Figure 1-12 As shown, this embodiment provides a linear track combined power supply and water supply device with start-up protection function, including a main unit 100 and a linear track conveying device 200 connected to the main unit 100.

[0087] The linear track conveying device 200 includes a linear track 2 and a trolley assembly disposed on the linear track 2. The trolley assembly reciprocates on the linear track 2 and is used to carry cables and convey them to the main equipment 100. The linear track conveying device 200 also includes a traction frame 8, one end of which is connected to the trolley assembly and the other end of which is connected to the main equipment 100. The cables are connected to the main equipment 100 through the traction frame 8.

[0088] It is understandable that the main equipment 100 is connected to the trolley assembly via the traction frame 8. When the main equipment 100 moves, it can drive the trolley assembly to move along the linear track 2 via the traction frame 8. In this way, no matter where the main equipment 100 moves, the linear track conveying device 200 can deliver cables to the main equipment 100, that is, the linear track conveying device 200 moves synchronously with the main equipment 100.

[0089] Specifically, the trolley assembly includes a conveyor belt 3, pulleys 4, trolley 5, and several wheels 16. The trolley 5 is supported on a horizontally arranged straight track 2 by pulleys 4 fixed at both ends. Two conveyor belts 3 with the same length and structure are symmetrically installed on the outer circumference of the pulleys 4 on both sides of the trolley in a wrapping manner. Several wheels 16 are all connected to the trolley 5 and can all be rotatably connected to the straight track 2.

[0090] Understandably, the two conveyor belts 3 are connected end to end by the upper traction frame 8 and the lower tensioning device 9, forming a closed loop covering the outside of the trolley 5; the cable guide frame 7 is evenly distributed on the two conveyor belts 3, and the cables and water cables are installed on the two conveyor belts 3 through the cable guide frame 7 and the cable fixing clamps 11 respectively; the tensioning device 9 is fixedly installed at the symmetrical midpoint of the straight track 2; the traction frame 8 is connected to the main equipment 100 through a transmission; and the two parallel straight tracks 2 of equal height are symmetrically installed between the two side columns 13 of the fixed support 1.

[0091] In this embodiment, multiple sets of conveyor belt support rollers 6 are fixedly installed on the upper part of the trolley 5 between two pulleys 4, so that the support rollers 6 can reduce the friction of the conveyor belt 3 when rotating. Multiple sets of conveyor belt brackets 10 are fixedly installed on the lower part of the fixed bracket 1. A set of conveyor belt cleaning devices 14 are respectively installed on the inner side of the support plates of the pulleys 4 at both ends of the trolley 5. A baffle plate 15 is set on the upper part of the trolley 5 within a certain range corresponding to the main machine.

[0092] It is worth noting that in traditional linear track combined power and water supply devices, the main equipment 100 is rigidly connected to the main equipment 100 via the traction frame 8. When the main equipment 100 (e.g., a lifting device) drives the trolley 5 to reciprocate along the linear track 2 via the traction frame 8, the speed of the main equipment 100 increases from zero at the moment of startup, and the instantaneous acceleration is very large. In addition, the trolley 5 and its components have a large mass, which causes the conveyor belt 3 to bear huge stress at the moment of startup of the main equipment 100, which can easily lead to a decrease in the performance of the conveyor belt 3.

[0093] Therefore, the linear track combined power supply and water supply device of this embodiment is also equipped with a start protection module 300, and its active end is rigidly connected to the main equipment 100, and its passive end is rigidly connected to the traction frame 8, so that the main equipment 100 drives the trolley 5 to reciprocate along the linear track 2 through the start protection module 300.

[0094] Through the start-up protection module 300, a slight relative displacement occurs between the main equipment 100 and the linear track conveyor 200 at the moment of start-up. As a result, the speed and acceleration of the traction frame 8 will decrease at the moment of start-up, ultimately reducing the stress on the conveyor belt 3 at the moment of start-up.

[0095] Specifically, in this embodiment, the start-up protection module 300 includes an active component 400 and a passive component 500. The active component 400 is rigidly connected to the device host 100 via a first connecting part 600, and the passive component 500 is rigidly connected to the traction frame 8 via a second connecting part 700. Thus, during startup, the device host 100 drives the active component 400 to move via the first connecting part 600, and the passive component 500 drives the trolley 5 to move via the second connecting part 700.

[0096] In this process, the active component 400 is in contact with the passive component 500, and in the first state, the active component 400 and the passive component 500 are in relative displacement; in the second state, the active component 400 and the passive component 500 are relatively fixed.

[0097] Therefore, in the first state, that is, at the moment the device host 100 starts, the active component 400 and the passive component 500 are relatively displaced; in the second state, that is, when the device host 100 is running smoothly, the active component 400 and the passive component 500 are relatively fixed.

[0098] With this configuration, at the instant the main unit 100 starts, the active component 400 and the passive component 500 generate relative displacement, thereby creating a slight relative displacement between the main unit 100 and the linear track conveyor 200, which are rigidly connected to the active component 400 and the passive component 500, respectively. Therefore, within the same time frame, the distance traveled by the traction frame 8 is shorter than the distance traveled by the main unit 100; that is, the speed and acceleration of the traction frame 8 decrease at the instant of startup.

[0099] In this embodiment, the active component 400 includes a first body 410 and a guide groove 420 mounted on the first body 410, with the guide groove 420 located on the front end face of the first body 410 (the side facing the passive component 500). Correspondingly, the passive component 500 includes a second body 510 and a guide block 520 mounted on the second body 510, with the guide block 520 located on the rear end face of the second body 510 (the side facing the active component 400). Thus, when the active component 400 and the passive component 500 experience relative displacement, their stability is ensured.

[0100] In this embodiment, the active component 400 further includes a plurality of protective teeth 430 disposed on the front end face of the first body 410, and the rear end face of the passive component 500 is fixedly mounted with mating teeth 530, and the shape and size of the mating teeth 530 match the protective teeth 430; the protective teeth 430 are configured to extend elastically out of the front end face of the first body 410 or partially retract into the front end face of the first body 410.

[0101] Therefore, in the first state, at the moment the host device 100 starts up, the speed increases from zero and the instantaneous acceleration is very large. The squeezing force between the protective tooth 430 and the mating tooth 530 exceeds the elastic force of the protective tooth 430. The protective tooth 430 partially retracts to the front end face of the first main body 410. During the retraction of the protective tooth 430, the active component 400 generates a relative displacement with respect to the passive component 500, that is, the acceleration of the passive component 500 is attenuated relative to the active component 400.

[0102] In the second state, the main unit 100 of the equipment enters a uniform speed state with an acceleration of approximately zero. The squeezing force between the protective tooth 430 and the mating tooth 530 does not exceed the elastic force of the protective tooth 430. The protective tooth 430 extends completely out of the front end face of the first main body 410. The active component 400 is fixed relative to the passive component 500, that is, the linear track conveying device 200 maintains synchronous movement.

[0103] Through the interaction of the protective tooth 430 and the mating tooth 530, at the moment the main equipment 100 starts, during the retraction of the protective tooth 430, the protective tooth 430 and the mating tooth 530 slide laterally, resulting in relative displacement between the active component 400 and the passive component 500. Therefore, during the start-up period, the distance traveled by the traction frame 8 is shorter than the distance traveled by the main equipment 100, and the speed and acceleration of the traction frame 8 experience start-up attenuation at the moment of start-up.

[0104] Specifically, the protective tooth 430 is a triangular tooth and is equipped with a first contact surface 431; correspondingly, the mating tooth 530 is equipped with a second contact surface.

[0105] In this embodiment, the front end face of the first main body 410 is provided with a mounting groove 440, and a tooth base module 450 is fixedly installed in the mounting groove 440. A plurality of protective teeth 430 can be elastically and retractably installed in the tooth base module 450, and the front end face of the tooth base module 450 is also provided with a receiving groove 451 so that the protective teeth 430 can retract into the receiving groove 451 in the first state.

[0106] The receiving groove 451 has stepped holes 452, and the number of them is the same as that of the protective teeth 430; correspondingly, the protective teeth 430 includes a tooth body 432 and a guide post 433 fixedly installed at the bottom of the tooth body 432, and the guide post 433 is installed in the stepped holes 452.

[0107] In this structure, the small hole 453 in the stepped hole 452 is located at the top, and the large hole 454 is located at the bottom. Correspondingly, the guide post 433 is a stepped shaft, with its small diameter portion 434 located at the top and disposed within the small hole 453, and its size matching that of the small hole 453. Its large diameter portion 435 is located at the bottom and disposed within the large hole 454, and its size matching that of the large hole 454. An elastic element 455 is also disposed within the large hole 454, with its upper end abutting against the lower end face of the guide post 433, thereby allowing the protective tooth 430 to elastically extend and retract.

[0108] Therefore, during the compression of the protective tooth 430, the elastic element 455 provides an upward elastic force to the protective tooth 430. Simultaneously, the large-diameter portion 435 cooperates with the large hole 454 to provide guidance, ensuring the stability of the protective tooth 430's movement. Furthermore, the large-diameter portion 435 cooperates with the small hole 453 to act as a limit, preventing the protective tooth 430 from disengaging from the stepped hole 452.

[0109] It is worth noting that the stepped hole 452 in this embodiment penetrates the tooth base module 450; and the tooth body 432 and the guide post 433 are detachable, the tooth base module 450 and the first body 410 are also detachable, and the lower end of the elastic element 455 abuts against the bottom surface of the mounting groove 440.

[0110] Therefore, when assembling the active component 400, the tooth body 432 is first placed in the receiving groove 451, then the guide post 433 is inserted through the large hole 454 and connected and fixed to the tooth body 432, then the elastic element 455 is inserted into the large hole 454 from the bottom, and finally the tooth base module 450 is placed in the mounting groove 440 and the first body 410 and the tooth base module 450 are fixed together.

[0111] When the elastic element 455, tooth body 432 or guide post 433 need to be replaced, the replacement steps are basically the reverse of the assembly steps of the active component 400, and will not be described in detail here.

[0112] The linear track combined power and water supply device with start-up protection function in this embodiment uses a modular assembly method for its active component 400, which facilitates the assembly and replacement of vulnerable parts such as the elastic element 455, the gear body 432, or the guide post 433. Furthermore, the smallest replacement unit for the active component 400 is the elastic element 455, the gear body 432, or the guide post 433, eliminating the need for complete replacement due to damage to a single component. This facilitates modular production, procurement, and spare parts availability, significantly reducing costs.

[0113] Specifically, a stud 436 is provided on the upper end face of the guide post 433, and correspondingly, a first threaded hole 437 is provided on the bottom of the tooth body 432, thereby realizing a detachable connection between the tooth body 432 and the guide post 433. In addition, an internal hexagonal hole 438 is also provided on the lower end face of the guide post 433 so that a wrench can be used to tighten the guide post 433.

[0114] The gear base module 450 has a second threaded hole 456 on its side wall, and the first body 410 has a third threaded hole 411 on its side wall. The position and parameters of the third threaded hole 411 match those of the second threaded hole 456. Thus, the gear base module 450 and the first body 410 are detachably connected by bolts 460.

[0115] It is understandable that the second threaded hole 456 can be set on the upper or lower side of the gear base module 450, or the second threaded hole 456 can be opened on both the upper and lower sides to increase the connection strength between the gear base module 450 and the first body 410.

[0116] Preferably, the third threaded hole 411 is a stepped hole, with an internal thread at the small end and a smooth hole at the large end; correspondingly, the bolt 460 is an internal hex bolt. This ensures that the bolt 460 does not protrude from the side wall of the first body 410, preventing the bolt 460 from interfering with the cable configuration.

[0117] In this embodiment, the first connecting part 600 includes a connecting body 610 and a connecting plate 620 mounted on the front end face of the connecting body 610. The connecting plate 620 has a plurality of oblong holes 630. Correspondingly, the rear end face of the first body 410 is provided with a mating connecting plate 470, which fits against the connecting plate 620. The mating connecting plate 470 has a plurality of connecting holes 471, and the positions of the connecting holes 471 match the oblong holes 630. Thus, threaded fasteners pass through the oblong holes 630 and the connecting holes 471, fixing the first connecting part 600 to the active component 400.

[0118] The rear end face of the connecting body 610 is provided with a mounting flange 640 so that the first connecting part 600 can be rigidly connected to the main equipment 100 through the mounting flange 640.

[0119] Understandably, for cost-saving reasons, the second connecting part 700 has the same structure as the first connecting part 600, the difference being the installation position. For example, the connecting plate 620 of the second connecting part 700 is located on the rear end face, while the mounting flange 640 is located on the front end face. It is worth noting that the fact that the second connecting part 700 has the same structure as the first connecting part 600 does not imply any limitation on its size.

[0120] Correspondingly, the front end face of the second main body 510 is provided with a second mating connecting plate 540, and the second mating connecting plate 540 is attached to the connecting plate 620. The second mating connecting plate 540 is provided with a plurality of second connecting holes 541, and the positions of the second connecting holes 541 match the oblong holes 630. Thus, the threaded fastener passes through the oblong holes 630 and the second connecting holes 541, fixing the second connecting part 700 to the passive component 500.

[0121] Understandably, during the operation of the protection module 300, the force analysis on the protection tooth 430 ignores the influence of friction and other factors, and approximates the vertical component of the compressive force on the protection tooth 430 as ( Figure 10 The angle of view is equal to the moving distance of the protective tooth 430 multiplied by the elastic coefficient of the elastic element 455.

[0122] Therefore, the instantaneous start-up speed of the main unit 100 varies under different operating conditions, and the compressive force on the protective teeth 430 also varies. If the vertical component of the compressive force exceeds the height value of the protective teeth 430 ( Figure 10 Multiplying the angle by the elastic coefficient of the elastic element 455 will cause the protective tooth 430 to retract completely, and the protective tooth 430 will disengage from the mating tooth 530, ultimately causing the active component 400 to be unable to drive the passive component 500, that is, the main unit 100 of the equipment cannot drive the linear track conveyor 200.

[0123] If the vertical component of the compressive force is less than the minimum vertical movement distance limit of the protective tooth 430 ( Figure 10 Multiplying the angle by the elastic coefficient of the elastic element 455 will result in insufficient retraction distance of the protective tooth 430, and too small relative displacement between the active component 400 and the passive component 500. Ultimately, this will result in insufficient attenuation of the speed and acceleration of the traction frame 8, which will not effectively reduce the stress borne by the conveyor belt 3 at the moment of startup.

[0124] To eliminate the aforementioned problems and enable the start-up protection module 300 to adapt to more operating conditions, as one embodiment of this method, the elastic elements 455 can be configured as two sets of springs with different elastic coefficients. Adaptably, the passive component 500 is also configured as two.

[0125] In another embodiment of this method, the protective teeth 430 can be configured as two sets of teeth with different parameters, that is, the inclination angle of the first contact surface 431 of the different sets of protective teeth 430 is different. Adaptably, the passive component 500 also needs to be configured as two, and the dimensions of the mating teeth 530 of the two passive components 500 are respectively matched with the two different sets of protective teeth 430.

[0126] With the above settings, the traction frame 8 is rigidly connected to different passive components 500. When the equipment main body 100 is instantaneously started, it is ensured that the vertical movement distance of the protection tooth 430 is within an ideal limit range, which can not only avoid the disengagement of the protection tooth 430 from the mating tooth 530 caused by the complete retraction of the protection tooth 430, but also avoid the excessive attenuation of the speed and acceleration of the traction frame 8 caused by the too small relative displacement between the active component 400 and the passive component 500. Finally, the start-up protection module 300 is made to adapt to more working conditions.

[0127] It can be understood that the type quantity of the elastic element 455 or the protection tooth 430 is not limited to two. Springs with different elastic coefficients and teeth with different parameters can also be set for different groups of protection teeth 430 at the same time. The deformations of the above two methods both belong to the equivalent technical solutions of this embodiment.

[0128] It is worth noting that the linear track combined power supply and water supply device with start-up protection function in this embodiment can be used for the switching of different working conditions of a set of equipment.

[0129] During the switching, the equipment main body 100, the first connecting part 600, the linear track conveying device 200, and the second connecting part 700 all remain stationary. Remove the threaded fasteners passing through the waist-shaped hole 630 and the connecting hole 471, and then move the active component 400 and the passive component 500 as a whole, so that the first connecting part 600 is aligned with different positions of the active component 400, and the second connecting part 700 is aligned with another passive component 500. Then, fix the first connecting part 600, the active component 400, the second connecting part 700, and the passive component 500 respectively through the threaded fasteners passing through the waist-shaped hole 630 and the connecting hole 471.

[0130] In this embodiment, a track 412 is provided on the rear end face of the first main body 410, and a track groove 413 in the shape of a "convex" character is opened in the track 412; correspondingly, a long slider 650 is fixedly installed on the rear end face of the connecting body 610 of the first connecting part 600, and the shape and size of the long slider 650 are the same as those of the track groove 413.

[0131] Thus, during the switching process, the long slider 650 always remains in the track groove 413, and it is not necessary to completely disengage the active component 400 from the first connecting part 600. It is only necessary to push the active component 400 back and forth. Thus, it is not necessary to hold the active component 400 throughout the switching process, which saves time and effort. At the same time, the setting of the track groove 413 in the shape of a "convex" character restricts the degrees of freedom of the active component 400 in the up, down, front, and rear directions.

[0132] Similarly, a second track 511 is provided on the front end face of the second main body 510, and a second track groove 512 in a "convex" shape is formed in the second track 511; correspondingly, a long slider 650 is fixedly installed on the front end face of the connection body 610 of the second connection part 700.

[0133] In this embodiment, a plurality of cable clips 480 are further provided on the upper side surface of the first main body 410 to ensure the smoothness of the cables and water cables.

[0134] As described above, only the preferred specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
