[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0049] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] like Figures 1 to 10 As shown, the utility model provides a material turnover device for circulating materials downward through the lifting hole 7, comprising:

[0051] The bearing member 1 has a height lower than that of the lifting hole 7;

[0052] Guide member 3: The guide member 3 is used to limit the moving direction of the rolling member 2, thereby improving the moving efficiency of the carrier 1. The guide member 3 is arranged on the 8th floor of the station hall and extends toward the lifting hole 7, so that the carrier 1 can approach or move away from the lifting hole 7 along the extension direction of the guide member 3. In this way, the carrier 1 can approach the lifting hole 7 in an empty manner, and after loading the material S, it can be moved away along the guide member 3 to facilitate unloading. At the same time, after the carrier 1 is moved away, the lifting hole 7 can also be exposed, which is convenient for conveying the material S from the ground 9 to the 8th floor of the station hall below. Of course, the carrier 1 loaded with materials can be guided out through the lifting hole 7 to achieve a rapid turnover of the material S.

[0053] The rolling member 2 is rotatably arranged at the bottom of the supporting member 1 and is located on the guide member 3; when the supporting member 1 moves along the extension direction of the guide member 3 under the driving force, the supporting member 1 can move toward the lifting hole 7 to the first position or move away from the lifting hole 7 to the second position; when the supporting member 1 is located at the first position, the supporting member 1 is located directly below the lifting hole 7, and when the supporting member 1 is located at the second position, the supporting member 1 is away from the lifting hole 7; the rolling member 2 is rotatably connected to the supporting member 1, which is convenient for workers to push the supporting member 1 to move easily and reduces labor intensity.

[0054] The material turnover device, when in use, pushes the carrier 1 to move toward the lifting hole 7. After the carrier 1 moves to the bottom of the lifting hole 7, the carrier 1 stops moving and stops at the bottom of the lifting hole 7, i.e., the first position. After the material S introduced from the lifting hole 7 is circulated to the carrier 1, the carrier 1 is pushed to move in the direction away from the lifting hole 7 and stops at a position away from the lifting hole 7, i.e., the second position.

[0055] In another embodiment, in the material turnover device, the bearing member moves along the extension direction of the guide member under the drive of the power device;

[0056] The material turnover device also includes:

[0057] The braking mechanism 101 is arranged on the carrier 1 and connected to the rolling member 2 for braking the carrier 1 ; the braking mechanism 101 is connected to the carrier 1 for braking the carrier 1 to maintain the position of the carrier 1 relative to the guide member 3 .

[0058] The detection mechanism 102 includes a pair of distance measuring sensors, which are spaced apart at the head and tail ends of the carrier 1 or on the guide member 3 (such as the two ends of the guide member 3), or each distance measuring sensor includes a transmitting end and a receiving end, the two transmitting ends are both arranged at the bottom of the carrier, and the two receiving ends are spaced apart on the guide member; the detection mechanism 102 is used to detect the current position of the carrier 1 relative to the guide member 3.

[0059] The controller 103 is connected to the pair of distance measuring sensors, the power device and the brake mechanism 101. When the pair of distance measuring sensors respectively detect that the carrier 1 reaches the set position, the controller 103 controls the action of the brake mechanism 101 to brake the carrier 1 and stop it at the first position or the second position. The controller 103 is communicatively connected to the detection mechanism 102 and the brake mechanism 101 to control the action of the brake mechanism 101 according to the current position information of the carrier 1 detected by the detection mechanism 102.

[0060] When a pair of distance measuring sensors are arranged at intervals at the head and tail ends of the carrier, two targets (such as the stopper 5 mentioned later) are arranged at intervals on the guide member. When the two distance measuring sensors respectively detect that the distance between the carrier and the two targets is equal to the braking distance value, the carrier reaches the set position.

[0061] When a pair of distance measuring sensors are spaced apart and arranged on the guide member, and the carrier moves close to and triggers the pair of distance measuring sensors, the carrier reaches the set position;

[0062] When each distance measuring sensor includes a transmitting end and a receiving end, and the receiving end of each distance measuring sensor receives a signal transmitted by the corresponding transmitting end, the bearing member reaches the set position.

[0063] In a possible embodiment, distance measuring sensors can be respectively arranged at the head and tail ends of the carrier 1, and two targets or obstacles are arranged at intervals on the guide member. The distance measuring sensor adopts an ultrasonic distance sensor, and its principle is to emit a very thin laser beam to the target during operation, and the laser beam reflected by the target is received by the photoelectric element, and the timer measures the time from the emission to the reception of the laser beam, thereby calculating the distance from the train to the obstacle. The ultrasonic distance sensor includes a transmitting probe and a receiving probe. The transmitting probe and the receiving probe are respectively connected to the transmitting circuit and the receiving circuit, and the transmitting circuit and the receiving circuit are connected to the single-chip microcomputer, and the single-chip microcomputer is connected to the signal processor (controller). The transmission and reception of the ultrasonic distance sensor and the timing of the round-trip time from the transmission to the reception of the ultrasonic wave are controlled by the single-chip microcomputer, so as to obtain the current distance value between the carrier 1 and the target. The signal processor compares the current distance value between the ultrasonic distance sensor and the target with a set safe braking distance value. If the signal processor determines that the current distance value is equal to the set braking distance value, a control command is sent to the emergency brake (brake mechanism). After receiving the control command, the emergency brake performs an emergency braking operation on the carrier 1 to stop the carrier 1 from moving in the shortest time (same as the use principle of the ultrasonic distance sensor, signal processor, and emergency brake in the first scheme of a train anti-collision warning device in the authorization announcement number CN 203888830 U). And stop at the first position or the second position.

[0064] In another possible embodiment, the braking mechanism 101 includes an electromagnetic brake. The detection mechanism 102 includes at least one pair of sensing chips, and the two ends of the guide member 3 are respectively provided with sensing chips. In this way, when the carrier 1 approaches and triggers the sensing chip, the sensing chip transmits the received electrical signal to the controller 103, and the controller 103 controls the electromagnetic brake to operate so that the carrier 1 stops moving, so that the carrier 1 can stop moving in time and effectively, ensuring the safety and reliability of the material S turnover device during operation.

[0065] In this case, the controller 103 can be configured as a control chip, which is connected to a pair of sensing chips. Of course, the controller 103 can also be configured as a PLC programmable logic controller 103, which can be configured according to the type and position of the detection mechanism 102.

[0066] In another possible embodiment, each distance measuring sensor includes a transmitting end and a receiving end, the two transmitting ends are arranged at the bottom of the carrier 1, and the two receiving ends are arranged at intervals at the two ends of the guide member, and when the receiving end of each distance measuring sensor receives the signal transmitted by the corresponding transmitting end, the carrier reaches the set position. The detection mechanism 102 includes two distance measuring sensors, the transmitting end of the distance measuring sensor is connected to the carrier 1, and the receiving end of the distance measuring sensor is arranged at the end of the guide member 3, so that the position of the carrier 1 is known through the communication between the receiving end and the transmitting end, and then the data is transmitted to the controller 103, so as to accurately control the motion state of the braking mechanism 101.

[0067] In the present disclosure, the rolling member 2 can be a roller, the power device that drives the roller to rotate can be a motor, and the electromagnetic brake can include a magnetic coil, a brake pad and a brake disc. The brake disc is connected to the support member 1 in a transmission manner. When current passes through the magnetic coil of the electromagnetic brake, the electromagnetic force attracts the brake pad, and the brake pad is used to release the brake disc. At this time, the drive shaft of the motor drives the brake disc to operate normally or start, that is, the brake disc can rotate equivalent to the roller, so that the support member 1 can move smoothly. When the current of the electromagnetic brake is cut off, the brake pad is separated from the brake disc, and a friction torque is generated between the brake disc, the brake pad and the flange, so that the drive shaft stops quickly. At this time, the brake disc stops rotating, so that the support member 1 is braked.

[0068] In addition, since the electromagnetic brake can be a commercially available product, its structure and working principle are common knowledge, so it will not be described in detail here. Of course, those skilled in the art can also make conventional improvements to the electromagnetic brake under the technical concept of the present disclosure.

[0069] When the detection mechanism 102 detects that the support member 1 is close to the target position (taking the guide member 3 as a reference object, the target position can be the two ends of the guide member 3), the controller 103 controls the braking mechanism 101 to operate according to the signal transmitted by the detection mechanism 102, thereby helping the support member 1 to slow down and gradually stop moving, thereby enabling the support member 1 to stop in a timely and effective manner, preventing damage to the construction environment and ensuring the safety of the construction process.

[0070] The material turnover device is suitable for the lifting holes 7 on the subway station hall 8, and the material turnover device can cooperate with the lifting holes 7 to circulate materials S between the ground 9 and the subway station hall 8.

[0071] The material turnover device, when in use, drives the support member 1 to move toward the lifting hole 7 through the rolling member 2. After a distance measuring sensor detects that the support member 1 has reached the preset position, the controller 103 controls the action of the braking mechanism 101 to brake the support member 1 and stop it directly below the lifting hole 7, i.e., the first position. After the material S introduced from the lifting hole 7 is circulated to the support member 1, the support member 1 is driven by the rolling member 2 to move away from the lifting hole 7. After another distance measuring sensor detects that the support member 1 has reached the preset position, the controller 103 controls the action of the braking mechanism 101 to brake the support member 1 and stop it at a position away from the lifting hole 7, i.e., the second position.

[0072] Through the above technical solution, based on the cooperation among the bearing member 1, the rolling member 2 and the guide member 3, the bearing member 1 can be quickly moved close to or away from the lifting hole 7, without the need for repeated manual disassembly and assembly, which greatly reduces the labor intensity of workers. In addition, the material turnover device can be used repeatedly and has low cost. At the same time, it has a simple structure and a small size, and is extremely suitable for the narrow space of the subway. At the same time, the bearing member 1 can stop running in a timely and effective manner, and has good flexibility and safety.

[0073] In the specific embodiment of the present disclosure, the rolling member 2 and the guide member 3 can be configured as any suitable structure.

[0074] In another embodiment, in the material turnover device, when the carrier 1 is located at the first position, the vertical projection of the lifting hole 7 is located within the vertical projection of the carrier 1. The carrier 1 is formed into a shape adapted to the lifting hole 7, and the cross-sectional area of ​​the carrier 1 is greater than or equal to the area of ​​the lifting hole 7, so that the carrier 1 can completely cover the lifting hole 7. In this way, the material S introduced from the lifting hole 7 can be completely circulated to the carrier 1. In addition, when the station hall 8 has multiple floors, it can also prevent the material S from falling from the lifting hole 7 on the floor where the carrier 1 is located into the station hall 8 on the lower floor during turnover, thereby eliminating safety hazards.

[0075] In another embodiment, in the material turnover device, the rolling member 2 includes at least two pairs of rollers, the guide member 3 is a pair of parallel guide rails, the at least two pairs of rollers are spaced apart along the length direction of the guide rails at the bottom of the support member 1, and each pair of rollers is located on a pair of guide rails. The rollers are configured as at least two pairs and spaced apart along the length direction of the guide rails. On the one hand, the support member 1 can move smoothly along the extension direction of the guide rails, and at the same time, it is also beneficial to evenly bear the gravity and reduce the pressure and wear on the rails. In the present disclosure, Figure 4 and Figure 5 As shown, the rollers are configured into two pairs, and the rollers at both ends are respectively arranged at the two ends of the bottom of the carrier 1. In other embodiments, the rollers can also be configured into three pairs, five pairs or any other suitable number, and the present disclosure does not limit this.

[0076] When a pair of distance measuring sensors are arranged at intervals at the head and tail ends of the carrier, a target object is arranged at each end of one of the pair of guide rails;

[0077] When a pair of distance measuring sensors are arranged at intervals on the guide member, the pair of distance measuring sensors are arranged at intervals at both ends of one of the pair of guide rails;

[0078] When each distance measuring sensor includes a transmitting end and a receiving end, the two receiving ends are arranged at intervals at the two ends of one of the pair of guide rails. The detection mechanism 102 includes two distance measuring sensors, the transmitting end of the distance measuring sensor is connected to the carrier 1, and the receiving end of the distance measuring sensor is arranged at the end of the guide member 3, so that the position of the carrier 1 is known through the communication between the receiving end and the transmitting end, and then the data is transmitted to the controller 103, so as to accurately control the motion state of the braking mechanism 101.

[0079] In another embodiment, in the material turnover device, each roller is provided with an annular groove along its circumferential direction, and a pair of guide rails respectively pass through the bottom of the annular groove of the roller corresponding thereto. The rolling element 2 may include at least two pairs of rollers, and the guide element 3 includes a pair of parallel guide rails; wherein, as an option, an annular groove matching the guide rail is provided on the roller, so that the roller can ride on the guide rail. In this way, the supporting element 1 can move along the guide rail through the matching of the annular groove and the guide rail. Based on the rotatable characteristic of the rolling element 2, the friction between the rolling element 2 and the guide rail can also be reduced, and the wear between the guide rail and the roller can be reduced.

[0080] In another scheme, in the material turnover device, a pair of guide rails are provided with grooves along their extension direction, and each roller is embedded in the corresponding groove. Among them, as another option, the guide rail can also be provided with grooves extending along its length direction, and the roller is embedded in the groove. Thus, through the cooperation of the roller and the groove, the carrier 1 can be moved quickly along the guide rail. It should be noted that the guide rail can be embedded in the base of the 8th floor of the subway station hall, and the guide rail can be lower than the upper surface of the base. In this way, the flatness of the base can be guaranteed, which is convenient for forklifts or other auxiliary equipment to move.

[0081] In another embodiment, in the material turnover device, a guardrail is provided at the outer edge of the carrier 1 along its circumferential direction, and the side of the guardrail away from the hoisting hole 7 is an open end. The carrier 1 may also be provided with a guardrail to prevent the material S from falling during the movement. The guardrail is vertically arranged around the circumferential direction of the carrier 1, which is beneficial to increase the stacking height, thereby accommodating more materials S. The side of the carrier 1 away from the hoisting hole 7 is set as an open end, so as to facilitate forklift or manual operation and facilitate loading or unloading.

[0082] In another embodiment, in the material turnover device, a first stopper 41 is provided at the bottom of the carrier 1, and a second stopper 42 is provided on the guide member 3. The first stopper 41 and the second stopper 42 are detachably connected; when the first stopper 41 and the second stopper 42 are connected, the carrier 1 is located at the first position. Figure 8 and Fig. 9 As shown, the support member 1 may be provided with a first limiter 41, and the guide member 3 may be provided with a second limiter 42. The first limiter 41 and the second limiter 42 are detachably connected, so that when the first limiter 41 and the second limiter 42 are connected, the position of the support member 1 relative to the lifting hole 7 can be maintained to prevent the support member 1 from continuing to slide along the guide rail after being squeezed or touched after reaching the preset position, thereby effectively improving the reliability of the position of the support member 1, which can facilitate workers to work (for example, lifting the material S to the outside world, etc.). When the connection between the first limiter 41 and the second limiter 42 is released, the support member 1 can be reset. It should be noted that the second limiter 42 is located around the lifting hole 7, which is convenient for workers to operate nearby.

[0083] In the specific implementation provided in the present disclosure, the first limiting member 41 and the second limiting member 42 may be connected in any suitable manner.

[0084] In another embodiment, in the material turnover device, the first stopper 41 and the second stopper 42 are detachably connected in a specific manner as follows:

[0085] The first limiting member 41 and the second limiting member 42 are both provided with through holes, and the through holes on the first limiting member 41 correspond to the through holes on the second limiting member 42 one by one, and each through hole on the first limiting member 41 is threadedly connected with the corresponding through hole on the second limiting member 42 through a matching bolt and nut assembly; as an option, Figure 8 and Fig. 9 As shown, the first stopper 41 can be connected to the second stopper 42 through a locking structure, and the locking structure includes a through hole and a fastener matched with the through hole, and the through holes are respectively arranged on the first stopper 41 and the second stopper 42. That is to say, the first stopper 41 and the second stopper 42 are connected by the fastener, thereby achieving the purpose of quick disassembly and assembly. Among them, the fastener can be a bolt and a nut, or a wire rope, a stopper pin.

[0086] Alternatively, one of the first limiter 41 and the second limiter 42 is a magnetic member, and the other is a metal member; as another option, the first limiter 41 and the second limiter 42 can also be connected by magnetic attraction. Specifically, one of the first limiter 41 and the second limiter 42 is a magnetic member, and the other of the first limiter 41 and the second limiter 42 is a metal member, and when the magnetic member is powered on and generates magnetic force, it can absorb the metal member, thereby maintaining the position of the carrier 1 relative to the guide rail. After power is turned off, the connection between the first limiter 41 and the second limiter 42 can be released.

[0087] Alternatively, the first limiting member 41 and the second limiting member 42 are connected via a clamping hoop. As another option, the first limiting member 41 and the second limiting member 42 may be connected via a clamping hoop.

[0088] Based on the above technical concept, those skilled in the art can flexibly configure it according to actual needs, and the present disclosure does not limit this.

[0089] In another embodiment, the material turnover device further includes:

[0090] A pair of stoppers 5 are provided at both ends of one of the pair of guide rails; when the carrier 1 is located at the first position or the second position, the carrier 1 is located between the pair of stoppers 5; when the carrier 1 is located at the first position, the carrier 1 is close to one of the stoppers 5; when the carrier 1 is located at the second position, the carrier 1 is close to the other of the stoppers 5; Figure 4 and Figure 5As shown, the material turnover device also includes a stopper 5 for limiting the moving range of the carrier 1, and the stopper 5 is arranged on the guide member 3. In this way, the carrier 1 is prevented from continuing to move beyond the range due to inertia during the moving process, causing accidents such as rollover, so that a reliable limiting effect is achieved through this mechanical structure.

[0091] As an option, the stop member 5 can be a parking wedge, so that the bearing member 1 can be braked in time, and the parking wedge is simple and easy to obtain, which is beneficial to reducing equipment costs. The parking wedge is detachably connected to the guide member 3, which is convenient for disassembly and maintenance of the parking wedge.

[0092] As another embodiment, the stop member 5 can also be configured as a limit pile, and the limit pile is a rubber column or a wooden pile, which can be flexibly arranged by those skilled in the art.

[0093] In order to further reduce the impact of the bearing member 1 on the stop member 5 when braking, a buffer pad can be provided on the stop member 5. The buffer pad can be made of any suitable flexible material such as rubber, cotton cloth or plastic, and the present disclosure does not limit this.

[0094] The slope pad 6 is detachably connected to the bearing member 1, and the slope pad 6 is located on the side of the bearing member 1 away from the lifting hole 7, such as Fig.10 As shown, the slope pad 6 is a right triangle, the slope of the slope pad 6 gradually slopes downward and away from the load-bearing member 1, and the height of the top of the slope pad 6 is equal to the height of the load-bearing surface of the load-bearing member 1. During the turnover of material S, there is a certain height difference between the load-bearing member 1 and the 8th floor of the station hall, which is not convenient for using a forklift or other equipment to turn over the material S. For this reason, Fig.10 As shown, a slope pad 6 can be provided to facilitate the use of a forklift or other device to labor-savingly batch-transfer materials S. In addition, the slope pad 6 is removably connected to the bearing member 1, so that the slope pad 6 can be selectively removed according to usage requirements, which has good flexibility and practicality.

[0095] In order to allow a forklift or other device to move smoothly between the load-bearing member 1 and the 8th floor of the station hall, the maximum height of the slope pad 6 is equal to the distance from the load-bearing surface of the load-bearing member 1 to the 8th floor of the station hall, so that the vibration of the forklift during driving can be reduced, and the material S can be prevented from being offset or scattered. Furthermore, the inclined surface of the slope pad 6 is a plane. Of course, in other embodiments, it can also be a curved surface, and the present disclosure does not limit this.

[0096] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
