Description

Technical Field

[0001] This utility model relates to the technical field of unloading machine equipment, and in particular to a mobile arched unloading machine. Background Technology

[0002] V-type mine cars are typically bottom-discharge or tipper-type unloading vehicles. Because the bottom is a sharp angle, the material can slide out quickly from the bottom opening with the help of gravity (bottom-discharge type) or slide down the V-shaped slope by tipping the car.

[0003] In the prior art, mine cars are usually unloaded automatically using arched unloading machines. For example, utility model patent with publication number CN223421928U discloses an arched unloading machine, which includes support columns, guide rails, tipping claws, etc., and uses a hydraulic motor to drive the tipping claws to move along the guide rails to achieve tipping and unloading of the mine cars.

[0004] However, this unloading machine can only unload at fixed points, which is inconvenient. In addition, it can only unload one mine car at a time, resulting in low work efficiency. Utility Model Content

[0005] This application provides a mobile arched unloading machine, which can flexibly move the tipping claws to achieve unloading at different positions, making unloading convenient. At the same time, it can also unload multiple mine cars at the same time, which can effectively improve work efficiency.

[0006] This application provides a mobile arched unloading machine, including a support base and a crossbeam. The top of the support base is provided with two horizontally parallel arched rails. The crossbeam is vertically sleeved on the two arched rails. Drive motors are installed at both ends of the crossbeam. The output shaft of the drive motors vertically penetrates into the crossbeam and is fixedly sleeved with drive wheels. The arched rails are provided with first pin teeth that cooperate with the drive wheels, so that the crossbeam can be driven by the drive motors to move directionally along the arched rails. At least two movable seats are sleeved on the crossbeam between the two arched rails. The bottom of the movable seats is connected to unloading claws. A movable motor is installed on one side of the movable seat. The output shaft of the movable motors vertically penetrates into the movable seats and is fixedly sleeved with second gears. The crossbeam is provided with second pin teeth that mesh with the second gears.

[0007] In one possible implementation, the drive motors located at both ends of the crossbeam are a first motor and a second motor, respectively. The drive wheel sleeved on the output shaft of the first motor is a first gear, which meshes with the first pin tooth. The drive wheel sleeved on the output shaft of the second motor is a driven wheel, which rolls with the first pin tooth.

[0008] In one possible implementation, the movable seats fitted on the crossbeam are 2 to 5 in number.

[0009] In one possible implementation, the two ends of the crossbeam are fitted with first lower rollers at the bottom, and the first lower rollers roll in engagement with the bottom of the arched curved track.

[0010] In one possible implementation, a second lower roller is mounted on the bottom of the movable seat, and the second lower roller rolls in cooperation with the crossbeam.

[0011] In one possible implementation, a power storage device is installed on the top of the support base on the side away from the arched curved track, and the power storage end of the power storage device is connected to the crossbeam via a steel wire rope.

[0012] In one possible implementation, the top of the support base is fitted with a housing suitable for accommodating the energy storage component on the side away from the arched track. The housing has an opening, the energy storage component is a rotary spring, and the wire rope passes through the opening and is connected to the energy storage end of the energy storage component.

[0013] Beneficial effects: Compared with the prior art, the mobile arched unloading machine provided in this application sets two curved or arched parallel curved rails on the top of the support base, and a crossbeam is fitted between the two arched curved rails. The crossbeam is equipped with a moving motor and unloading claws. The drive motors at both ends of the crossbeam can drive the crossbeam to move the unloading claws along the arched curved rails in a directional manner to complete the unloading. At the same time, the moving motor can flexibly adjust the position of the unloading claws, i.e. the unloading position, no longer limited to fixed-point unloading, making unloading more convenient. With the cooperation of multiple unloading claws, multiple mine cars can be unloaded at the same time, resulting in higher work efficiency.

[0014] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0021] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] refer to Figures 1 to 5This application provides a mobile arched unloading machine, including a support base 10 and a crossbeam 20. The top of the support base 10 has two horizontally arranged arched curved rails 30, which are either arched or curved. The crossbeam 20 is vertically mounted on the two arched curved rails 30, and drive motors 21 are installed at both ends of the crossbeam 20. The output shaft of the drive motor 21 vertically penetrates into the crossbeam 20 and is fixedly fitted with a drive wheel. Correspondingly, the arched curved rails 30 have first pin teeth 31 that cooperate with the drive wheels, thereby enabling the crossbeam 20 to move directionally along the arched curved rails 30 via the drive motors at both ends. Furthermore, at least two movable seats 40 are fitted on the crossbeam 20 between the two arched curved rails 30. At the same time, the bottom of the movable seat 40 is connected to the unloading claw 50, and a movable motor 41 is installed on one side of the movable seat 40. The output shaft of the movable motor 41 extends vertically into the movable seat 40 and is fixedly fitted with a second gear 42. Correspondingly, the crossbeam 20 is provided with a second pin tooth 22 that meshes with the second gear 42. Thus, the movable seat 40 can be driven to move directionally on the crossbeam 20 based on the meshing relationship between the second gear 42 and the second pin tooth 22, thereby adjusting the position of the unloading claw 50.

[0024] During operation, based on the meshing relationship between the second gear 42 and the second pin 22, the moving motor 41 can drive the moving seat 40 to move directionally along the crossbeam 20, thereby flexibly adjusting the position of the unloading claw 50 to form an adjustable moving unloading claw 50. This allows for flexible adjustment of the unloading position, moving beyond fixed-point unloading and making unloading more convenient. Based on the length of the crossbeam 20, multiple moving seats 40 can be mounted on the crossbeam 20, such as 2-5. When the drive motor 21 drives the crossbeam 20 to move directionally along the arched curved track 30, the cooperation of multiple unloading claws 50 enables simultaneous unloading of multiple mine cars, resulting in higher work efficiency.

[0025] In the phrase "the arched curved rail 30 is provided with a first pin tooth 31 that cooperates with the drive wheel", the first pin tooth 31 on the arched curved rail 30 can simultaneously mesh with the drive wheels at both ends. At this time, the drive motors 21 at both ends need to operate synchronously to drive the crossbeam 20 to move on the arched curved rail 30. However, considering that the synchronization of the drive motors 21 at both ends may be poor in some cases, which may damage the first pin 31 or the drive wheel, in one embodiment, the drive motors 21 at both ends of the crossbeam 20 are a first motor 211 and a second motor 212, respectively. The drive wheel on the output shaft of the first motor 211 is a first gear 213, which meshes with the first pin 31. That is, the outer surface of the first gear 213 has external teeth that mesh with the first pin 31. The drive wheel on the output shaft of the second motor 212 is a driven wheel 214, which rolls with the first pin 31. That is, the driven wheel 214 is a passive rotating wheel with no external teeth on its outer surface. The driving power mainly comes from the first gear 213. During movement, the driven wheel 214 rolls and rubs with the first pin 31. In this way, even if the drive motors 21 at both ends are out of sync, the first pin 31 and the drive wheel will not be damaged.

[0026] In one embodiment, the two ends of the crossbeam 20 are equipped with first lower rollers 23 at the bottom, and the first lower rollers 23 roll in cooperation with the bottom of the arched curved track 30. Thus, the first lower rollers 23 can provide rolling support, making the movement of the crossbeam 20 on the arched curved track 30 more stable.

[0027] In one embodiment, a second lower roller 43 is installed at the bottom of the movable seat 40, and the second lower roller 43 rolls in cooperation with the crossbeam 20. Thus, the second lower roller 43 can play a rolling support role, making the movement of the movable seat 40 on the crossbeam 20 more stable.

[0028] In one embodiment, a power storage component 11 is installed on the top of the support base 10 on the side away from the arched curved track 30. At the same time, the power storage end of the power storage component 11 is connected to the crossbeam 20 through a steel wire rope 12, so that the stored energy can be released through the power storage component 11 during the return phase of the crossbeam 20, providing additional reset assistance to the drive motor 21 and improving the overall efficiency of the unloading operation.

[0029] More preferably, the top of the support base 10 is provided with a housing 13 on the side away from the arched curved rail 30, which is suitable for accommodating the energy storage member 11 and for installing and limiting the energy storage member 11. The housing 13 is provided with an opening, wherein the energy storage member 11 is preferably a rotary spring, and the wire rope 12 passes through the opening and is connected to the energy storage end of the energy storage member 11.

[0030] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
