Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a conveyor frame, a conveyor, and a crushing station. Background Technology

[0002] Mobile crushing plants, characterized by their integrated unit design, flexibility, and on-site modularity, are increasingly favored by customers. Currently, mobile crushing plants are typically transported as a whole unit via trailer. Due to limitations in transport size and height, foldable conveyors are often used to reduce the overall transport size and height of the equipment. After arriving at the construction site, the equipment is quickly deployed to bring the mobile crushing plant to normal operating status.

[0003] In existing technologies, foldable conveyors are designed in sections, including a fixed section and a folding section. The fixed section is fixedly connected to the frame of the crushing station, while the folding section is hinged to the fixed section. By rotating the folding section relative to the fixed section, the conveyor can be folded and unfolded. The fixed section is inclined and cantilevered. Due to limitations in the material strength of both the fixed and folding sections, the conveyor is prone to bending under the weight of the conveyor and the material it transports, thus limiting its length and preventing long-distance transport. Furthermore, because the fixed section has a fixed inclination angle on the frame, certain requirements must be placed on the inclination angle to ensure effective material transport, further limiting the conveyor's transport height.

[0004] Therefore, how to solve the problem of limited conveying length and height in existing conveyors has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0017] According to the present invention, a conveyor frame further includes:

[0018] The first drive cylinder has its two ends respectively disposed on the bearing side of the third frame and on the frame body, and is configured to drive the third frame to rotate relative to the second frame.

[0019] According to the present invention, a conveyor frame further includes:

[0020] A linkage assembly is disposed at the second end of the first frame and the first end of the second frame. The linkage assembly includes a first link and a second link. The first end of the first link is rotatably connected to the first frame, the first end of the second link is rotatably connected to the second frame, and the second end of the first link is rotatably connected to the second end of the second link.

[0021] The second drive cylinder is configured to drive the first connecting rod to rotate relative to the first frame or to drive the second connecting rod to rotate relative to the second frame.

[0022] According to the present invention, a conveyor frame is provided, wherein the first frame comprises:

[0023] The first frame body has a second end that is rotatably connected to the second frame;

[0024] A first roller mounting bracket is disposed at the first end of the first frame body, and the relative position of the first roller mounting bracket and the first frame body along the extension direction of the first frame body is adjustable;

[0025] And / or, the third rack includes:

[0026] The third frame body, the first end of which is rotatably connected to the second frame;

[0027] The second roller mounting bracket is disposed at the second end of the third frame body, and the relative position of the second roller mounting bracket and the third frame body along the extension direction of the third frame body is adjustable.

[0028] According to a conveyor frame provided by the present invention, at least two elastic material buffer strips are provided on the bearing side of the third frame, the buffer strips extend along the extension direction of the third frame, and the distribution direction of each buffer strip is perpendicular to the extension direction of the third frame.

[0029] The present invention also provides a conveyor, including a frame and a conveyor frame disposed on the frame, wherein the conveyor frame is the conveyor frame described above.

[0030] The present invention also provides a crushing station, including a frame and a conveyor disposed on the frame;

[0031] The conveyor is the conveyor described above, or the conveyor includes the conveyor frame described above.

[0032] The conveyor frame provided by this invention is used to be installed on the frame of a crushing station. Combined with components such as conveyor belts and rollers, it can transport materials output from the crusher away from the crusher. The conveyor frame includes a first frame, a second frame, and a third frame, with the second frame located between the first and third frames. The first frame is located at the first end of the second frame, and the second end of the first frame is rotatably connected to the first end of the second frame.

This configuration, with both ends of the second frame connected to the main frame, reduces bending deformation of the second frame, facilitating an increase in its length and consequently increasing the conveyor's conveying length.

[0033] Furthermore, when the conveyor frame provided by this invention is installed on the frame of the crushing station, the second frame can be rotated relative to the frame by adjusting the extension and retraction of the first telescopic rod. Different lengths of the first telescopic rod result in different tilt angles of the second frame relative to the frame, thus adjusting the tilt angle of the conveyor. With a fixed conveying length, appropriately adjusting the tilt angle of the second frame allows the conveyor to have different conveying heights, further solving the problem of limited conveying height.

[0034] Furthermore, the conveyor provided by the present invention also possesses the various advantages described above due to having the conveyor frame as described above.

[0035] Furthermore, the crushing station provided by the present invention also possesses the various advantages described above due to the presence of the conveyor frame or conveyor as described above. Attached Figure Description

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0051] The following is combined with Figures 1 to 11 The conveyor frame of the present invention is described.

[0052] like Figures 1 to 11 As shown, the conveyor frame provided in this embodiment of the invention is used to be installed on the frame 1 of the crushing station. Combined with components such as conveyor belts and rollers, it can transport the material output by the crusher away from the crusher.

[0053] The conveyor frame includes a first frame 4, a second frame 2 and a third frame 5, with the second frame 2 located between the first frame 4 and the third frame 5.

[0054] Specifically, the first frame 4 is disposed at the first end of the second frame 2, and the second end of the first frame 4 is rotatably connected to the first end of the second frame 2. The third frame 5 is disposed at the second end of the second frame 2, and the first end of the third frame 5 is rotatably connected to the second end of the second frame 2. By rotating the first frame 4 and the third frame 5 relative to the second frame 2, the conveyor frame can be folded and unfolded.

[0055] The first end of the second frame 2 is provided with a first telescopic rod 3, the first end of which is rotatably connected to the second frame 1, and the length of the first telescopic rod 3 can be adjusted. When the conveyor frame is installed on the frame 1 of the crushing station, the second end of the second frame 2 is rotatably connected to the frame 1, and the second end of the first telescopic rod 3 is rotatably connected to the frame 1.

[0056] With this configuration, both ends of the second frame 1 are connected to the frame 2, which reduces the bending deformation of the second frame 2, facilitates increasing the length of the second frame 2, and consequently increases the conveying length of the conveyor. With a fixed tilt angle of the conveyor, the increase in the conveying length leads to a corresponding increase in the conveying height, solving the problem of limited conveying length and height in existing technologies.

[0057] Furthermore, when the conveyor frame provided in this embodiment of the invention is installed on the frame 1 of the crushing station, the second frame 2 can be rotated relative to the frame 1 by adjusting the extension and retraction of the first telescopic rod 3. Different lengths of the first telescopic rod 3 result in different tilt angles of the second frame 2 relative to the frame 1, thus adjusting the tilt angle of the conveyor. With a fixed conveying length, appropriately adjusting the tilt angle of the second frame 2 allows the conveyor to have different conveying heights, further solving the problem of limited conveying height.

[0058] It should be noted that there are two first telescopic rods 3, which are distributed along the width direction of the second frame 2. The width direction of the second frame 2 is parallel to the bearing surface of the second frame 2 and perpendicular to the extension direction of the second frame 2. The second frame 2 is connected to the frame body 1 by the two first telescopic rods 3, which helps to improve the stability and reliability of the second frame 2.

[0059] The rotation axes of the first frame 4 relative to the second frame 2, the rotation axis of the second frame 2 relative to the frame 1, the rotation axis of the third frame 5 relative to the second frame 2, the rotation axis of the first telescopic rod 3 relative to the second frame 2, and the rotation axis of the first telescopic rod 3 relative to the frame 1 are parallel to each other and are all along the width direction of the second frame 2.

[0060] In this embodiment of the invention, the conveyor frame further includes a second telescopic rod 6. The first end of the second telescopic rod 6 is rotatably connected to the second frame 2. The first end of the second telescopic rod 6 is located between the rotatable connection point between the second frame 2 and the frame body 1 and the connection point between the first end of the first telescopic rod 3 and the second frame 2. When the conveyor frame is installed on the frame body 1 of the crushing station, the second end of the second telescopic rod 6 needs to be rotatably connected to the frame body 1. The rotation axis of the second telescopic rod 6 relative to the second frame 2 and the rotation axis of the second telescopic rod 6 relative to the frame body 1 are parallel and both are along the width direction of the second frame 2.

[0061] The installation of the second telescopic rod 6 increases the connection between the second frame 2 and the frame 1, which can improve the stability and reliability of the second frame 2.

[0062] The length of the second telescopic rod 6 can be adjusted to accommodate the telescopic adjustment of the first telescopic rod 3 and the different tilt angles of the second frame 2.

[0063] The second telescopic rod 6 and the first telescopic rod 3 can be set on the same side of the second frame 2. Specifically, the rotation axis of the second telescopic rod 6 relative to the frame 1 and the rotation axis of the first telescopic rod 3 relative to the frame 1 can be made to coincide, so that the first telescopic rod 3, the second telescopic rod 6 and the second frame 2 form a triangular structure, which can enhance the stability of the connection structure between the second frame 2 and the frame 1, and further improve the stability and reliability of the second frame 2.

[0064] The first telescopic rod 3 and the second telescopic rod 6 can be positioned on the load-bearing side of the second frame 2, or they can be positioned on the non-load-bearing side of the second frame 2. When the second frame 2 is installed on the frame 1, the load-bearing side of the second frame 2 is the upper part of the second frame 2, and the non-load-bearing side of the second frame 2 is the lower part of the second frame 2. When the first telescopic rod 3 and the second telescopic rod 6 are located on the load-bearing side of the second frame 2, they exert a tensile force on the first end of the second frame 2, that is, the first end of the second frame 2 is connected to the frame 1 by suspension. When the first telescopic rod 3 and the second telescopic rod 6 are located on the non-load-bearing side of the second frame 2, they exert an upward supporting force on the first end of the second frame 2. (Refer to...) Figures 1 to 3 In this embodiment, the first telescopic rod 3 and the second telescopic rod 6 are set on the bearing side of the second frame 2.

[0065] The rotatable connection between the first telescopic rod 3 and the second frame 2, the rotatable connection between the first telescopic rod 3 and the frame 1, the rotatable connection between the second telescopic rod 6 and the second frame 2, and the rotatable connection between the second telescopic rod 6 and the frame 1 can all be achieved by means of pin hinge.

[0066] The first telescopic rod 3 and the second telescopic rod 6 have the same structure, both including a sleeve, a first connecting rod, and a second connecting rod. The first and second connecting rods extend into the sleeve from both ends, and are threadedly connected to the sleeve. The thread direction on the first connecting rod is opposite to that on the second connecting rod. Taking the first telescopic rod 3 as an example, after hinged to the second frame 2 and the second connecting rod to the frame 1, the first and second connecting rods can be moved closer or further apart by screwing the sleeve, thereby achieving the extension and retraction of the first telescopic rod 3.

[0067] In this embodiment of the invention, the rotational connection between the third frame 5 and the second frame 2 is achieved by a hinge. Specifically, the second end of the second frame 2 and the first end of the third frame 5 are hinged together by a connecting shaft 7, the axis of which is arranged along the width direction of the second frame 2. The end of the connecting shaft 7 extends beyond the second frame 2 and the third frame 5, that is, the end of the connecting shaft 7 has a suspended portion relative to the second frame 2 and the third frame 5.

[0068] A slot 8 is provided on the frame 1, which allows the suspended part to extend into. After the suspended part extends into the slot 8, it ensures that the suspended part can rotate relative to the frame 1, thereby realizing the rotatable connection between the second frame 2 and the frame 1, which facilitates the assembly and disassembly of the second frame 2 and the frame 1.

[0069] The bottom surface of card slot 8 can be tilted, as shown in the reference. Figure 11After the conveyor frame is installed on the frame 1 of the crushing station, the weight of the conveyor frame and the material it conveys can prevent the suspended part from coming out of the slot 8, thus ensuring the stability of the second frame 2.

[0070] When the conveyor frame is in its unfolded state, the bearing surfaces of the first frame 4, the second frame 2, and the third frame 5 are coplanar. To ensure the smooth passage of the crushing plant, the third frame 5 needs to rotate upwards when folded.

[0071] like Figure 7 As shown, the connecting shaft 7 is positioned close to the non-load-bearing side of the second frame 2 and the third frame 5. The shapes of the first end of the third frame 5 and the second end of the second frame 2 are designed so that when the third frame 5 is rotated upwards to its limit position, the angle between the load-bearing surface of the third frame 5 and the load-bearing surface of the second frame 2 is less than 180 degrees. At this point, when folding the conveyor frame, the third frame 5 needs to rotate upwards relative to the second frame 2. When unfolding the conveyor frame, the third frame 5 can rotate downwards relative to the second frame 2.

[0072] In this embodiment, the conveyor frame also includes a suspension member 9, which is disposed between the bearing side of the third frame 5 and the frame body 1. The first end of the suspension member 9 is connected to the third frame 5, and the second end of the suspension member 9 can be detachably connected to the frame body 1.

[0073] When the conveyor frame needs to be unfolded, the third frame 5 is rotated downward relative to the second frame 2 to the target position, and then the second end of the suspension member 9 is connected to the frame body 1. When the conveyor frame needs to be folded, the second end of the suspension member 9 is disconnected from the frame body 1, and then the third frame 5 is rotated upward relative to the second frame 2.

[0074] The first end of the suspension member 9 is spaced from the first end of the third frame 5. Specifically, the first end of the suspension member 9 can be positioned adjacent to the second end of the third frame 5.

[0075] In a further embodiment, at least two connection positions can be provided on the suspension member 9, the distance between any two connection positions and the first end of the suspension member 9 is different, and each connection position can be connected to the frame 1.

[0076] When different connection points on the suspension component 9 are connected to the frame 1, the distance between the first end of the suspension component 9 and the frame 1 is different, and correspondingly, the tilt angle of the third frame 1 is also different. By switching the connection points connected to the frame 1, the tilt angle of the third frame 1 can be adjusted.

[0077] Specifically, the aforementioned suspension component 9 can be, but is not limited to, a chain or rope. In this case, a connection hole is provided on the frame 1.

[0078] When a rope is selected as the suspension element 9, after passing the rope through the connecting hole, the rope is knotted according to the required tilt angle of the third frame 1 to connect the rope to the frame 1.

[0079] When a chain is selected as the suspension element 9, different links of the chain can be connected to the connecting holes on the frame 1. (Refer to...) Figure 6 The connecting hole has a locking seam. After determining the chain link that needs to be connected to the connecting hole, the corresponding chain link can be locked into the locking seam. Through the interaction between the adjacent chain links and the side wall of the locking seam, the chain can be prevented from coming out of the connecting hole.

[0080] In this embodiment, to facilitate the rotation of the third frame 5, the conveyor frame also includes a first drive cylinder 10. The first drive cylinder 10 is disposed between the bearing side of the third frame 5 and the frame 1. The two ends of the first drive cylinder 10 are respectively connected to the bearing side of the third frame 5 and the frame 1. The first drive cylinder 10 can drive the third frame 5 to rotate relative to the second frame 2.

[0081] The first drive cylinder 10 may be, but is not limited to, a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0082] In this embodiment, a hydraulic cylinder is selected as the first drive cylinder 10. The cylinder barrel of the hydraulic cylinder is hinged to the frame 1, and the piston rod of the hydraulic cylinder is hinged to the third frame 5. The extension and retraction of the hydraulic cylinder can drive the third frame 5 to rotate relative to the second frame 2, which can reduce manual operation and help reduce the labor intensity of the operators.

[0083] In this embodiment, a sensor is installed on the third frame 5, and two limit switches are installed on the frame 1. When the third frame 5 rotates relative to the second frame 1, the sensor triggers the limit switches. The two limit switches are a first limit switch and a second limit switch. When the third frame 5 rotates to the folded state, the sensor triggers the first limit switch; when the third frame 5 rotates to the unfolded state, the sensor triggers the second limit switch. Both the first and second limit switches are electrically connected to the crushing plant's control system. When the second limit switch is triggered, the crushing plant's control system restricts the crushing plant's movement; when the first limit switch is triggered, the crushing plant's control system restricts the normal operation of the crushing plant, thereby ensuring the safe operation of the crushing plant.

[0084] In this embodiment, the frame 1 of the crushing station is configured as a baseless structure. That is, the frame 1 includes two side plates 19 and support rods 20. The two side plates 19 are arranged opposite each other with a gap between them. Multiple support rods 20 are arranged between the two side plates 19 and are spaced apart. When the conveyor frame of this embodiment is installed on the frame 1 of the crushing station, the conveyor frame is located between the two side plates 19. When designing the position of the support rods 20, it is necessary to avoid placing them below the third frame 5 as much as possible. There are no support rods 20 or any base or bottom plate below the conveyor frame, allowing the third frame 5 to rotate relative to the second frame 2 within a large angle range. When maintenance of the crushing station is required, the third frame 5 can be rotated downwards as much as possible to create a larger space between the third frame 5 and the crusher, facilitating operation by the personnel.

[0085] To facilitate the installation of the conveyor frame, through holes are made on the two side plates 19 at the positions corresponding to the slots 8 and the positions corresponding to the suspension components 9 and the first drive cylinder 10, so that it is convenient to observe and operate during installation. The connection between the third frame 5 and the frame 1 can be completed from the outside of the frame 1.

[0086] In some embodiments, a first limiting hole is provided at the second end of the second frame 2, and a second limiting hole 21 is provided at the first end of the third frame 5, so that when the third frame 5 rotates relative to the second frame 2 to a certain position, the first limiting hole and the second limiting hole 21 are aligned. When the conveyor frame is installed on the frame 1 of the crushing station, pins or bolts can be used to pass through the first limiting hole and the second limiting hole 21 to fix the third frame 5 relative to the second frame 2, ensuring the stability of the conveyor frame during hoisting and improving operational safety.

[0087] In this embodiment of the invention, the conveyor frame further includes a connecting rod assembly and a second drive cylinder 13, with the connecting rod assembly disposed at the second end of the first frame 4 and the first end of the second frame 2.

[0088] Specifically, the linkage assembly includes a first link 11 and a second link 12. The first end of the first link 11 is rotatably connected to the first frame 4, the first end of the second link 12 is rotatably connected to the second frame 2, and the second end of the first link 11 is rotatably connected to the second end of the second link 12.

[0089] The rotation axis of the first link 11 relative to the first frame 4, the rotation axis of the second link 12 relative to the second frame 2, and the rotation axis of the first link 11 relative to the second link 12 are parallel to each other and are all along the width direction of the second frame 2.

[0090] The rotatable connection between the first link 11 and the first frame 4, the rotatable connection between the second link 12 and the second frame 2, and the rotatable connection between the first link 11 and the second link 12 can all be achieved by means of pin hinge.

[0091] The second drive cylinder 13 is used to drive the deformation of the connecting rod assembly. The connecting rod assembly allows the first frame 4 to rotate relative to the second frame 2 within a large angle range, which helps to reduce the angle between the first frame 4 and the second frame 2 when the first frame 4 is folded, reduce the length and height of the conveyor frame when folded, and increase the uphill and downhill slope angles when the crushing station is traveling.

[0092] Specifically, the second drive cylinder 13 can drive the first connecting rod 11 to rotate relative to the first frame 4, or the second drive cylinder 13 can drive the second connecting rod 12 to rotate relative to the second frame 2.

[0093] The second drive cylinder 13 can be mounted on either the first frame 4 or the second frame 2. To reduce the load on the hinge axis between the first frame 4 and the second frame 2, and to reduce the load on the second drive cylinder 13, the second drive cylinder 13 can be mounted on the second frame 2.

[0094] The second drive cylinder 13 may be, but is not limited to, a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0095] In this embodiment, a hydraulic cylinder is selected as the second drive cylinder 13. The cylinder barrel of the hydraulic cylinder is hinged to the second frame 2, and the piston rod of the hydraulic cylinder is hinged to the first connecting rod 11. The extension and retraction of the hydraulic cylinder can drive the first frame 4 to rotate relative to the second frame 2, which can reduce manual operation and help reduce the labor intensity of the operators.

[0096] Reference Figure 7 In this embodiment, the second end of the second connecting rod 12 is hinged to the middle position of the first connecting rod 11, and the piston rod of the hydraulic cylinder is hinged to the second end of the first connecting rod 11, which can further increase the range of rotation angles of the first frame 4. In this embodiment, the maximum rotation angle of the first frame 4 relative to the second frame 2 is close to 180 degrees.

[0097] To ensure the stability of the first frame 4 and the second frame 2 during conveyor operation, locking members 22 are provided at the second end of the first frame 4 and the first end of the second frame 2. The first end of the locking member 22 is rotatably connected to the second end of the first frame 4, with the axis of rotation perpendicular to the extension direction and width direction of the first frame 4. A locking plate with an open slot is provided at the first end of the second frame 2, allowing the locking member to move in and out of the open slot during rotation. When the locking member enters the open slot, it is threadedly connected to the locking member by a fastener 23, which abuts against the locking plate. Through the interaction between the fastener 23 and the locking plate, the rotation of the locking member relative to the first frame 4 is restricted. The relative rotation of the first frame 4 and the second frame 2 is restricted by the interaction between the first locking member and the first frame 4, and the interaction between the first locking member and the second frame 2.

[0098] Both the first end of the first frame 4 and the second end of the third frame 5 are used to install rollers. In a specific embodiment, only the first frame 4 can be configured as a structure with adjustable roller position, only the third frame 5 can be configured as a structure with adjustable roller position, or both the first frame 4 and the third frame 5 can be configured as structures with adjustable roller position.
