Description

Technical Field

[0001] This utility model relates to an automatic anchor bolt binding machine for mining, belonging to the field of mining equipment. Background Technology

[0002] Bundling is a crucial step in the production of anchor bolts. Anchor bolts are generally long and slender rods, making them prone to becoming scattered during production, transportation, and storage. Bundling is essential to ensure orderly placement and facilitate subsequent operations and use. However, current bundling methods often involve manually tidying and stacking the scattered anchor bolts before using bundling equipment to achieve a rounded shape. This method has significant drawbacks: the bundled bolts tend to loosen during transport, making it difficult to maintain a tight bond. This becomes especially problematic when bundling large quantities of anchor bolts, leading to inefficiency and unreliable quality. This not only affects the subsequent use and transportation of the anchor bolts but also creates numerous inconveniences in production.

[0003] Currently, the common method for binding anchor bolts is to bind multiple anchor bolts into a circle. Compared to binding multiple anchor bolts into a hexagon, the hexagon provides more even stress distribution and makes the bundled anchor bolts more stable during transportation. Therefore, this application designs a device for binding multiple anchor bolts into a hexagon. Utility Model Content

[0004] The purpose of this invention is to provide an automatic anchor bolt binding machine for mining, which can effectively solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The device includes a mounting base with a hexagonal frame that has an opening at the top. The two uppermost sides of the hexagonal frame are rotatably disposed, and a drive device for controlling the rotation angle of the sides is provided on both sides of the sides.

[0007] Furthermore: the hexagonal frame includes a base plate, on both sides of the base plate being integrally formed with inclined plates inclined at a 60-degree angle outwards, with hinge plates fixed at the front and rear ends of the inclined plates, and a rotating shaft being provided between the hinge plates, with the side key connected to the rotating shaft.

[0008] Furthermore: the driving device includes a hydraulic cylinder, the piston end of the hydraulic cylinder is rotatably connected to the side via a first hinge structure, and the cylinder body end of the hydraulic cylinder is rotatably mounted on the mounting base via a second hinge structure.

[0009] Furthermore: mounting plates are provided on both sides of the mounting base, and the second hinge structure is fixed on the mounting plates.

[0010] Furthermore, the number of hexagonal frames is two.

[0011] Furthermore: the lower end of the mounting base is provided with a transverse reciprocating device, the transverse reciprocating device including a sliding plate fixed on the lower end face of the mounting base, the sliding plate being transversely slidably disposed on the upper end face of the substrate.

[0012] Furthermore, a crank cam mechanism is also provided on one side of the sliding plate. The crank cam mechanism includes a limiting plate with a limiting groove. A pushing block is slidably disposed in the limiting groove. A connecting rod is rotatably disposed on the pushing block. One end of the connecting rod is rotatably connected to the driving wheel. The driving wheel is rotatably disposed on the sliding plate, and a drive motor is disposed on the sliding plate. The output end of the drive motor is connected to the driving wheel through a rotating shaft.

[0013] The beneficial effects are:

[0014] 1. The anchor rods are arranged in a hexagonal frame. Compared with the traditional circular binding method, the hexagonal structure distributes the force more evenly, and the bound anchor rods are more stable, making them easier to transport and store.

[0015] 2. By using a transverse reciprocating device in conjunction with a crank cam mechanism, the hexagonal frame is made to vibrate laterally, causing the anchor rod to automatically adjust its position and ultimately form a regular hexagon, improving the binding accuracy and reducing human intervention.

[0016] 3. This device uses a hydraulic cylinder to drive the opening and closing of the side, realizing the automatic clamping and release of the anchor bolts. Combined with the lateral vibration function, it reduces the workload of manually handling the anchor bolts and improves production efficiency. Attached Figure Description

[0029] See Figure 1-5 This is one embodiment of the automatic anchor bolt binding machine for mining according to this utility model.

[0030] It includes a mounting base 1, a hexagonal frame 2, a drive unit 3, a mounting plate 4, a transverse reciprocating device 5, and a crank cam mechanism 6.

[0031] The main function of the equipment is to bind multiple mining anchor bolts into a hexagonal shape, making them more stable during transportation and stacking, and improving the uniformity of stress distribution.

[0032] The hexagonal frame 2 is used to define the arrangement of the anchor rods, so that they are bundled into a regular hexagon. The upper end of the hexagonal frame 2 is set as an opening, through which the anchor rods can be directly put into the hexagonal frame 2.

[0033] The specific structure of the hexagonal frame 2 includes a base plate 22, an inclined plate 23, and a side 21 rotatably mounted on the inclined plate 23; the base plate 22 is the basic component of the hexagonal frame 2, providing support and serving as the bottom surface for anchor rod placement.

[0034] The inclined plate 23 is inclined outward at 60° from both sides of the base plate 22 and is integrally formed with the base plate 22; to prevent the anchor rods from rolling, so that they automatically move towards the center and form a hexagonal arrangement.

[0035] The hinge plate 24 is set at the front and rear ends of the inclined plate 23 to fix the rotation shaft 25 and provide a support structure so that the two sides 21 of the hexagonal frame 2 can rotate around the rotation shaft 25.

[0036] Side 21: The two top sides of the rotatable hexagonal frame. Its main function is to open the opening at the top of the hexagonal frame 2 when placing the anchor rod, so that the anchor rod can be placed into the hexagonal frame 2. After a certain number of anchor rods are placed, the driving device 3 controls the closing of the side 21 to limit the position of the anchor rod, so that the anchor rod can be tied up by the automatic binding device. Finally, after the anchor rod is tied up, the driving device 3 controls the side 21 to open again, so that the tied anchor rod can be lifted out.

[0037] Rotating shaft 25: Keyed to side 21, serving as the rotation center of side 21, enabling it to open and close under the action of drive device 3.

[0038] The drive device 3 in this device is used to control the opening and closing of the side 21 of the hexagonal frame 2 in order to complete the binding or release of the anchor rod. The specific structure includes a hydraulic cylinder 31, a first hinge structure 32 provided at the piston end of the hydraulic cylinder 31, and a second hinge structure 33 provided at the cylinder body of the hydraulic cylinder 31.

[0039] The hydraulic cylinder 31 is the core drive component, which controls the extension and retraction of the piston to control the rotation of the side 21. When it extends, it pushes the side 21 to rotate inward, pressing the anchor rod to form a hexagonal binding state. When it retracts, it pulls the side 21 to rotate outward, releasing the anchor rod and facilitating unloading.

[0040] The first hinge structure 32 and the second hinge structure 33 are mainly designed to enable the thrust of the hydraulic cylinder 31 to be effectively transmitted to the side 21 to achieve rotational action.

[0041] The mounting base 1 of this device serves as the basic support structure for the entire equipment. Mounting plates 4 are provided on both sides of the mounting base 4 for fixing the drive device 3. One mounting plate is provided on each side to fix the second hinge structure 33, so that the hydraulic cylinder 31 does not shift during operation, ensuring the stable transmission of driving force.

[0042] The lower end of the mounting base 1 is connected to the transverse reciprocating device 5, which allows the entire equipment to be adjusted in the transverse position. More importantly, the transverse reciprocating device 5 can be used to control the equipment on the mounting base 1 to vibrate rapidly in the transverse direction, so that multiple anchor rods can form a hexagonal structure under vibration.

[0043] The anchor bolts in this device are hollow, not solid, so they are relatively lightweight; therefore, the force required to drive the entire device in lateral reciprocating motion does not need to be very large.

[0044] The transverse reciprocating device 5 of this device mainly works with the crank cam mechanism 6 to make the anchor rod vibrate laterally, so as to facilitate the formation of a hexagonal structure.

[0045] Because after the anchor rods are placed in the hexagonal frame 2, they may not naturally align into a tight hexagon due to the shape of the anchor rods themselves, their placement method, or the influence of friction. At this time, the transverse reciprocating device 5 drives the hexagonal frame 2 to reciprocate in a small amplitude along the horizontal direction, thereby continuously adjusting the position between the anchor rods and eventually forming a uniform hexagonal arrangement.

[0046] The transverse reciprocating device 5 includes a sliding plate 51 and a base plate 52. The sliding plate 51 is fixed to the lower end face of the mounting base 1 and can slide left and right along the upper end face of the base plate 52 to realize the adjustment of the device position. The base plate 52 serves as a support structure for the sliding plate 51, ensuring sliding stability and enabling the device to adjust its position smoothly.

[0047] The crank-cam mechanism 6 in this device includes a limiting plate 61, a limiting groove 62, a pushing block 63, a connecting rod 64, a driving wheel 65, a drive motor 66, and a rotating shaft 67.

[0048] The limiting plate 61 is fixed to one side of the sliding plate 51 to restrict the movement trajectory of the push block 63 and ensure that it slides along the set route.

[0049] The limiting groove 62 is formed on the limiting plate 61, providing a sliding path for the pushing block 63, allowing it to move along the groove, thereby driving the sliding plate 51 to move left and right.

[0050] The push block 63 is slidably disposed in the limiting groove 62 and connected to the drive wheel 65 through the connecting rod 64. When the drive wheel 65 rotates, the push block 63 moves back and forth along the limiting groove 62, thereby pushing the sliding plate 51 to slide and realizing the lateral vibration of the equipment.

[0051] One end of the connecting rod 64 is connected to the push block 63, and the other end is connected to the drive wheel 65, converting the rotational motion of the drive wheel into the linear motion of the push block 63.

[0052] The drive wheel 65 is fixedly mounted on the sliding plate 51. By rotating, it drives the connecting rod 64 to move, causing the push block 63 to slide along the limiting groove 62, and finally driving the sliding plate 51 to move.

[0053] The drive motor 66 is fixed on the sliding plate 51 and provides power to the entire crank cam mechanism 6. Its output end is connected to the drive wheel 65 through the rotating shaft 67.

[0054] The rotating shaft 67 is used to transmit the power of the drive motor 66 to the drive wheel 65, so that the drive wheel 65 rotates, thereby driving the entire crank cam mechanism 6 to work.

[0055] The working process of this equipment is as follows:

[0056] First, the anchor rod is placed in the hexagonal frame 2: the operator or automatic feeding mechanism places the anchor rod on the base plate 22, and the anchor rod automatically moves closer together under the action of the inclined plate 23.

[0057] Next, the drive device 3 presses the anchor rod: the hydraulic cylinder 31 extends and drives the side 21 to rotate inward through the first hinge structure 32, pressing the anchor rod tightly together to form a stable hexagon.

[0058] Then the anchor bolts are secured using specialized automatic securing equipment, which is a feature found in all automatic securing machines and is not specified in this application. During securing, the equipment is placed at both ends of the anchor bolts, and the hexagonal anchor bolts are secured with nylon tape. This securing method is very common in the field.

[0059] Then, the hydraulic cylinder 31 retracts, causing the side 21 to rotate outward, forming an opening, and the crane is used to lift out the bundled anchor rod.

[0060] During the process of forming the anchor rods into a hexagon, the device uses a transverse reciprocating device 5 in conjunction with a crank cam mechanism 6 to make the entire device vibrate laterally. The hexagonal frame 2 then vibrates slightly in the horizontal direction, forcing the anchor rods to squeeze each other and adjust their positions, making them more closely arranged.

[0061] At the same time, this process is carried out simultaneously with the extension of the hydraulic cylinder 31, vibrating and retracting at the same time, which is more efficient.

[0062] This invention is applicable to the mass anchor bolt binding in scenarios such as mines and tunnels, improving binding quality and production efficiency.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
