[0018] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0019] Embodiment 1: The present invention provides an elevator receiving platform, please refer to Figure 1-Figure 18 The elevator receiving platform is mainly used in special environments such as mines. Its core is the car 2 and receiving system 3 set in the support 1 in the well. The car 2 is a carrier for transporting people or goods, and the receiving system 3 installed at the bottom is a key component for achieving smooth and efficient docking with the mine leveling.

[0020] For details, please refer to Figure 4 , the undertaking system 3 includes: The receiving platform 31: It adopts a U-shaped drawer structure, which not only ensures sufficient bearing space but also enables flexible adjustment in the up and down directions when adjusting the relative height between the load and the mine level. Its working principle is to achieve lifting and lowering through the screw rod 21 that matches the nut seat 311 symmetrically arranged at the bottom of the car 2 and on both sides of the receiving platform 31. For example, when it is necessary to raise the receiving platform 31, the screw rod 21 rotates forward, driving the nut seat 311 to move upward, thereby raising the receiving platform 31, and vice versa; The receiving plate 32: The side away from the door of the car 2 is rotatably connected to the inner wall of the receiving platform 31, and the side close to the door of the car 2 is provided with a hydraulic system 4. The hydraulic system 4 accurately adjusts the horizontal angle of the receiving plate 32 by controlling the inflow and outflow and pressure of the hydraulic oil. For example, during the loading process, in order to facilitate pushing the goods into the car 2, the outer end of the receiving plate 32 can be raised to a certain angle, and the hydraulic system 4 inputs high-pressure oil to the corresponding hydraulic cylinder to push the piston out, so that the receiving plate 32 rotates around the rotation connection point with the receiving platform 31. A storage groove 321 is provided on one side of the receiving plate 32 for storing the spacing compensation plate 33, so that it can be compactly placed in the receiving plate 32 when not in use, saving space.

[0021] The spacing compensation plate 33: A guide rail 331 matching the receiving groove 321 is provided at one end thereof, and the whole can be slidably inserted in the receiving plate 32. A rack 332 meshing with the main driving gear 64 is provided on one side of the guide rail 331. When the main driving gear 64 rotates, the spacing compensation plate 33 is driven to extend and retract horizontally along the length direction of the receiving plate 32 under the guidance of the guide rail 331 through meshing with the rack 332, so as to adjust the spacing between the car 2 and the mine level.

[0022] The lap plate 34 is rotatably connected to the end of the spacing compensation plate 33, and two sets of parallel rod groups 5 are rotatably connected on both sides. The function of the parallel rod group 5 is to adjust the flip angle of the lap plate 34 following the telescopic state of the spacing compensation plate 33. For example, when the spacing compensation plate 33 extends outward, the rod ends of the parallel rod group 5 slide in the flip guide grooves 312 and the horizontal guide grooves 313 on both sides of the inner wall of the receiving platform 31, driving the lap plate 34 to flip downward to a horizontal state until it overlaps on the mine level, providing a transition channel for the entry and exit of personnel or goods. When the spacing compensation plate 33 is retracted inward, the rod ends of the parallel rod group 5 slide in the flip guide grooves 312 and the horizontal guide grooves 313 on both sides of the inner wall of the receiving platform 31, and use the reset elastic force of the reset spring 314 to drive the lap plate 34 to flip upward to a vertical state until the door of the car 2 is closed, providing protection for the personnel or goods carried.

[0023] The car 2 is also provided with a transmission mechanism 6 at the bottom of the receiving system 3. The transmission mechanism 6 is used to adjust the vertical spacing between the receiving platform 31 and the car 2, and the horizontal spacing between the spacing compensation plate 33 and the car 2 in a time-sharing manner. Specifically, the drive motor 65 fixed at the bottom of the car 2 is the power source of the entire transmission mechanism 6. The output end of the drive motor 65 is respectively connected to the main pulley 63 and the main drive gear 64 through the time-sharing mechanism. The main pulley 63 is rotatably connected to the bottom of the car 2, and the main drive gear 64 is rotatably connected to the inside of the receiving plate 32. The existence of the time-sharing mechanism enables the drive motor 65 to drive the main pulley 63 and the main drive gear 64 in a time-sharing manner to avoid interference caused by the two working at the same time; Please refer to the Figure 5 In addition, a horizontal distance sensor 203 is also provided on the car 2: it is installed on the car 2 to monitor the horizontal distance between the car 2 and the mine level in real time. Its working principle is usually based on laser ranging or ultrasonic ranging technology, by transmitting signals and receiving reflected signals, the distance between the two is calculated, and the data is transmitted to the elevator control system, so that the control system can adjust the action of the distance compensation plate 33 and other components according to the data.

[0024] The first distance sensor 201 is used to monitor the vertical distance between the car 2 and the receiving plate 32. It also uses a similar distance measurement principle to provide data support for ensuring a safe distance between the receiving plate 32 and the car 2 and subsequent precise adjustment.

[0025] The second distance sensor 202 monitors the vertical distance between the car 2 and the mine level. The data of this sensor plays a key role in ensuring that the height of the car 2 matches the mine level during the up and down movement and maintaining the relative height stability of the receiving system 3 and the mine level during the loading and unloading process.

[0026] See also Figure 7-15, the specific connection of the transmission mechanism 6: the output end of the driving motor 65 is connected to a driving shaft 651, and the outer side of the driving shaft 651 is connected to a sleeve 8 in a limited sliding connection in the vertical direction. The bottom inner side of the sleeve 8 is connected to a transmission shaft rod 9 in a sliding connection in the vertical direction. The bottom of the car 2 is connected to a locking sleeve 7 in a limited sliding connection in the vertical direction. The middle part of the main pulley 63 is provided with a first spline groove 631, and the top of the sleeve 8 is provided with a first spline shaft 81 matched with the first spline groove 631. This spline connection method can ensure reliable power transmission with the main pulley 63 when the sleeve 8 moves up and down. An upper locking tooth 632 is provided at the bottom of the main pulley 63, a lower locking tooth 71 matching with the upper locking tooth 632 is provided at the top of the locking sleeve 7, a permanent magnet ring 82 is rotatably connected to the bottom of the shaft sleeve 8, a second tensioning spring 83 is fixed between the permanent magnet ring 82 and the bottom of the locking sleeve 7, an electromagnetic ring 67 matching with the permanent magnet ring 82 is also fixed to the bottom of the car 2, when the electromagnetic ring 67 is energized, the magnetic field generated by it interacts with the permanent magnet ring 82, overcomes the elastic force of the second tensioning spring 83, drives the locking sleeve 7 and the shaft sleeve 8 to move, and realizes the switching of the time-sharing working mode; Please refer to the figure, the time-sharing mechanism includes a driving shaft 651 fixed on the output shaft of the driving motor 65, and a sleeve 8 is connected to the outer side of the driving shaft 651 in a limited sliding manner in the vertical direction. The inner wall of the sleeve 8 is provided with a fourth spline groove 84, and the outer wall of the driving shaft 651 is provided with a fourth spline shaft 652 that matches the fourth spline groove 84. This spline connection method ensures that the sleeve 8 can slide on the driving shaft 651 in the vertical direction while realizing power transmission. The inner side of the bottom of the sleeve 8 is connected to a transmission shaft rod 9 in a sliding manner in the vertical direction, and the bottom of the car 2 is connected to a locking sleeve 7 in a limited sliding manner in the vertical direction. The middle part of the main pulley 63 is provided with a first spline groove 631, the top of the sleeve 8 is provided with a first spline shaft 81 that matches the first spline groove 631, the bottom of the main pulley 63 is provided with an upper locking tooth 632, and the top of the locking sleeve 7 is provided with a lower locking tooth 71 that matches the upper locking tooth 632.

[0027] Specifically, the bottom of the transmission shaft 9 is provided with a third spline shaft 93, and the inner top of the driving shaft 651 is provided with a third spline groove 653 matched with the third spline shaft 93. This spline connection ensures that the transmission shaft 9 and the driving shaft 651 can slide relative to each other while transmitting power. An upper coupling shaft 641 is fixed to the middle of the main driving gear 64, and the bottom of the upper coupling shaft 641 is connected to the lower coupling shaft 68 through a universal joint 66. The function of the universal joint 66 is to allow the upper coupling shaft 641 and the lower coupling shaft 68 to rotate relative to each other within a certain angle range to adapt to different working angle changes of the receiving plate 32 relative to the receiving platform 31.

[0028] A second spline shaft 92 is fixed to the top of the transmission shaft 9, a second spline groove 682 matching the second spline shaft 92 is provided at the bottom of the lower coupling shaft 68, and a first tensioning spring 681 is fixed between the second spline groove 682 and the second spline shaft 92. The first tensioning spring 681 ensures that the transmission shaft 9 can keep the third spline shaft 93 of the transmission shaft 9 at the bottom of the third spline groove 653 when it is not subjected to the upward thrust of the sleeve 8, so that the transmission connection between the transmission shaft 9 and the drive shaft 651 can be effectively disconnected. At the same time, the downward elastic force of the first tensioning spring 681 on the transmission shaft 9 also ensures that when the receiving platform 31 moves up and down within a certain range, the third spline shaft 93 effectively maintains the transmission separation state with the third spline groove 653. A retaining ring 91 matching the top of the first spline shaft 81 is fixed to the middle part of the transmission shaft 9. The function of the retaining ring 91 is to push the transmission shaft 9 to move up synchronously when the sleeve 8 moves up.

[0029] Among them, the inner wall of the sleeve 8 is provided with a fourth spline groove 84, and the outer wall of the drive shaft 651 is provided with a fourth spline shaft 652 matched with the fourth spline groove 84. This spline connection realizes the power transmission and relative sliding between the sleeve 8 and the drive shaft 651. The second tensioning spring 83 has the elastic force to drive the locking sleeve 7 to move down and approach the permanent magnet ring 82. Under normal conditions, the locking sleeve 7 is kept in a certain position under the action of the second tensioning spring 83. The magnetic pole of the electromagnetic ring 67 is variable. By controlling the direction and size of the current passing through the electromagnetic ring 67, its magnetic pole can be changed, thereby realizing attraction or repulsion between the permanent magnet ring 82, and then controlling the movement of the locking sleeve 7 and the sleeve 8, and realizing the functional switching of the time-sharing mechanism.

[0030] When the main pulley 63 needs to work, the electromagnetic ring 67 is energized and generates magnetic attraction to the permanent magnet ring 82. At this time, the sleeve 8 moves downward, so that the first spline shaft 81 is inserted into the first spline groove 631. At the same time, the second tensioning spring 83 is used to drive the locking sleeve 7 to move downward, so that the lower locking tooth 71 is separated from the upper locking tooth 632. The power of the driving motor 65 is transmitted to the main pulley 63 through the driving shaft 651 and the sleeve 8, so as to realize the power transmission to the main pulley 63 and meet the height adjustment requirements of the receiving platform 31. When it is necessary to drive the main drive gear 64, the electromagnetic ring 67 changes its magnetic pole and repels the permanent magnet ring 82, driving the locking sleeve 7 and the shaft sleeve 8 to move upward, so that the first spline shaft 81 disengages from the first spline groove 631, and at the same time, the second tensioning spring 83 is used to push the locking sleeve 7 upward, so that the lower locking tooth 71 is aligned with the upper locking tooth 632, and then the main pulley 63 is locked to maintain the adjusted height of the receiving platform 31. At the same time, the upward movement of the shaft sleeve 8 contacts the retaining ring 91, driving the transmission shaft 9 to move upward, so that the third spline shaft 93 is aligned with the third spline groove 653. At this time, the power of the driving motor 65 is transmitted to the main drive gear 64 through the driving shaft 651 and the transmission shaft 9, thereby realizing the horizontal telescopic adjustment of the receiving plate 32.

[0031] The cooperation between the receiving platform 31 and the receiving plate 32: The receiving platform 31 is a U-shaped drawer structure. The side of the receiving plate 32 away from the door of the car 2 is rotatably connected to the inner wall of the receiving platform 31 through a rotating connection piece such as a pin shaft, forming a rotatable connection node. The side of the receiving plate 32 close to the door of the car 2 is provided with a hydraulic system 4, and the hydraulic system 4 includes components such as a hydraulic cylinder, a hydraulic pump, and a control valve. When the horizontal angle of the receiving plate 32 needs to be adjusted, the hydraulic pump delivers hydraulic oil to the hydraulic cylinder through the control valve, pushing the piston rod of the hydraulic cylinder to extend or retract, thereby driving the receiving plate 32 to rotate around the rotating connection point to achieve angle adjustment. A receiving groove 321 is provided on one side of the receiving plate 32, and a guide rail 331 matching the receiving groove 321 is provided at one end of the spacing compensation plate 33. A high-precision sliding fit is adopted between the guide rail 331 and the receiving groove 321 to ensure the stability and accuracy of the spacing compensation plate 33 during the sliding process. The spacing compensation plate 33 is integrally slidably inserted in the receiving plate 32. A rack 332 meshing with the main drive gear 64 is provided on one side of the guide rail 331. When the main drive gear 64 rotates, the spacing compensation plate 33 is driven to slide on the guide rail 331 through meshing with the rack 332, thereby compensating for the spacing between the car 2 and the mine level.

[0032] Lifting transmission of the receiving platform 31: Two sets of nut seats 311 are symmetrically arranged on both sides of the receiving platform 31, and the bottom of the car 2 is rotatably connected with a screw rod 21 matching the nut seat 311. A synchronous belt 61 is sleeved on the main pulley 63, and a driven pulley matching the synchronous belt 61 is arranged at the bottom of the screw rod 21. The synchronous belt 61 is sleeved between the main pulley 63 and the driven pulley to form a cross-star belt winding. When the main pulley 63 rotates driven by the driving motor 65, the power is transmitted to the driven pulley through the synchronous belt 61, thereby driving the screw rod 21 to rotate. Due to the threaded cooperation between the nut seat 311 and the screw rod 21, the rotation of the screw rod 21 is converted into the up and down movement of the nut seat 311, thereby realizing the lifting and lowering of the receiving platform 31. The bottom of the car 2 is also rotatably connected to multiple sets of pressing rollers 62, which are in conflict with the outer wall of the synchronous belt 61 in contact with the main pulley 63. The function of the pressing rollers 62 is to ensure that the synchronous belt 61 always remains in a tensioned state during operation, avoid belt slippage, and improve power transmission efficiency.

[0033] Flipping adjustment of the lap plate 34: The lap plate 34 is rotatably connected to the end of the spacing compensation plate 33, and a rotatable connection is achieved through a rotating connection piece such as a pin. Two sets of parallel rod groups 5 are rotatably connected on both sides of the lap plate 34, and the parallel rod group 5 is composed of two mutually parallel rods connected by a pin. When the spacing compensation plate 33 is extended and retracted, the rod ends of the parallel rod group 5 slide in the guide grooves on both sides of the inner wall of the receiving platform 31, thereby driving the lap plate 34 to flip. For example, when the spacing compensation plate 33 extends outward, the rod ends of the parallel rod group 5 slide in the flipping guide groove 312 and the horizontal guide groove 313, so that the lap plate 34 flips downward until it overlaps on the mine level; when the spacing compensation plate 33 retracts, the parallel rod group 5 drives the lap plate 34 to flip upward and return to the initial position.

[0034] Both sides of the inner wall of the receiving platform 31 are provided with a flip guide groove 312, and a horizontal guide groove 313 is provided in the flip guide groove 312. A slide 315 is provided in the flip guide groove 312, and two groups of rod ends of the parallel rod group 5 are rotatably connected to the two ends of the slide 315. A first slider 3151 matching the flip guide groove 312 is fixed at one end of the slide 315, and a second slider 3152 matching the horizontal guide groove 313 is fixed at the other end. A reset spring 314 is also fixed between the first slider 3151 and the receiving platform 31. When the spacing compensation plate 33 is extended, the second slider 3152 slides in the horizontal guide groove 313, driving the slide 315 to move along the flip guide groove 312, and at the same time, the parallel rod group 5 drives the lap plate 34 to flip; when the spacing compensation plate 33 is retracted, under the action of the reset spring 314, the first slider 3151 drives the slide 315 and the second slider 3152 to reset, and the lap plate 34 is also reset accordingly. The groove depth of the horizontal guide groove 313 is greater than that of the flip guide groove 312. The horizontal guide groove 313 is a horizontal groove structure, one end of which is a horizontal groove, and the groove width of the other end gradually increases. The maximum groove width of the horizontal guide groove 313 is equal to the distance between the first slider 3151 and the second slider 3152. This design ensures that the slide 315 can slide smoothly in the horizontal guide groove 313 and realize different guiding functions at different positions.

[0035] Please refer to the Figure 16-Figure 18 The present application also provides a receiving method of an elevator receiving platform, which specifically includes the following steps: S1, the car 2 runs to the corresponding mine level, and uses the data monitored by the second spacing sensor 202 and the first spacing sensor 201 to keep the plane of the receiving plate 32 higher than the mine level; S2. Using the data collected by the horizontal spacing sensor 203, the transmission mechanism 6 drives the spacing compensation plate 33 to move outward to the designed spacing through the time-sharing mechanism, and uses the outward movement of the spacing compensation plate 33 to drive the overlapping plate 34 to flip and overlap on the mine level layer; S3. According to the requirements of loading or unloading cargo in the car 2, the tilt angles of the receiving plate 32 and the spacing compensation plate 33 are adjusted through the hydraulic system 4; S4. Utilize the data collected by the second spacing sensor 202 to calculate the height change amplitude of the car 2 during loading or unloading, and the transmission mechanism 6 drives the receiving platform 31 as a whole to adjust its height through the time-sharing mechanism, so as to achieve that the relative height of the receiving system 3 as a whole to the mine level does not change during loading and unloading.

[0036] When the car 2 runs to the corresponding mine level, the second spacing sensor 202 and the first spacing sensor 201 start working and transmit the monitored data to the control system. The control system controls the hydraulic system 4 based on these data to make the plane of the docking plate 32 higher than the mine level, preparing for the subsequent docking work.

[0037] The horizontal distance sensor 203 collects the horizontal distance data between the car 2 and the mine level in real time, and transmits the data to the control system. Based on the data, the control system controls the drive motor 65 to drive the main drive gear 64 to rotate through the time-sharing mechanism. The main drive gear 64 meshes with the rack 332 on one side of the guide rail 331 of the spacing compensation plate 33, driving the spacing compensation plate 33 to move outward. When the spacing compensation plate 33 moves outward to a certain distance, the lap plate 34 at its end is flipped under the action of the parallel rod group 5 and overlapped on the mine level, providing a channel for people or goods to enter and exit.

[0038] According to the need to load or unload goods in the car 2, the operator starts the hydraulic system 4 through the control system. The hydraulic system 4 adjusts the inclination angle of the receiving plate 32 and the spacing compensation plate 33 by controlling the inflow and outflow and pressure of the hydraulic oil to meet the placement and transportation requirements of different goods. For example, when the car 2 is unloading goods, the angle of the receiving plate 32 can be appropriately adjusted so that the cargo trolley can be pushed out of the car 2 without resistance, or when transporting irregularly shaped goods, the angle of the receiving plate 32 can be accurately adjusted through the hydraulic system 4 to ensure that the goods are placed stably.

[0039] Since the car 2 is mostly pulled by a steel wire rope, and since the steel wire rope has a certain deformation amount, even after the steel wire rope is fixed, during the process of loading or unloading the car 2, due to the change in the weight of the goods, the height of the car 2 will change, affecting the angle of the receiving plate 32 after adjustment. At this time, the second spacing sensor 202 collects the vertical spacing data between the car 2 and the mine level in real time, and transmits the data to the control system. Based on the data, the control system calculates the height change amplitude of the car 2, and then controls the drive motor 65 to drive the main pulley 63 to rotate alone through the time-sharing mechanism. The main pulley 63 drives the driven pulley through the synchronous belt 61, and then rotates the screw rod 21 to adjust the overall height of the receiving platform 31. In this way, the receiving system 3 as a whole can maintain its relative height to the mine level without changing during the loading and unloading process, ensuring the safe and stable transportation of personnel and goods.

[0040] The present invention can accurately adjust the horizontal and vertical distances between the car and the mine level by setting a receiving platform 31, a receiving plate 32, a spacing compensation plate 33 and a lap plate 34, as well as a corresponding transmission mechanism 6 and a sensor to ensure smooth docking. The receiving plate 32 can flexibly adjust the load angle through the hydraulic system 4 to meet the transportation needs of different goods. During the loading and unloading process, the second spacing sensor 202 monitors the vertical distance between the car and the mine level in real time. When the weight of the goods changes and the height of the car changes, the control system controls the drive motor 65 in the transmission mechanism 6 according to the sensor data, drives the main pulley 63 through the time-sharing mechanism, and then drives the screw 21 to rotate, adjust the height of the receiving platform 31, keep the relative height of the receiving system and the mine level stable, and improve transportation efficiency and safety.

[0041] The above are only the best implementation methods adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
