Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to an anchor rod storage component of an anchor rod trolley and a rod feeding method. Background Art

[0002] In the process of using the anchor trolley for mine support, the anchor rods need to be installed. In order to improve the efficiency of anchor support, the anchor rods need to be stored directly on the anchor trolley. Therefore, it is necessary to design a corresponding anchor rod warehouse for storing batches of anchor rods and ensure that they can be quickly taken out during use. When the anchor trolley is performing the process of drilling anchor holes, since the drilling assembly and the anchor rod pushing device are integrated on the swing frame, in order to avoid affecting the drilling, the swing frame will rotate the drilling assembly and the anchor rod pushing device away from the anchor rod warehouse. When drilling the anchor rod, the swing frame will be driven to bring the anchor rod pushing device closer to the anchor rod. Chinese patent application CN114856464A discloses an anchor rod warehouse and an operating arm of an anchor trolley with the anchor rod warehouse. In order to facilitate the removal of anchor rods, a special anchor rod grabbing device is required, which makes the structure complicated and increases the production and maintenance costs. Summary of the Invention

[0003] The present invention provides an anchor rod storage assembly of an anchor rod trolley and a rod delivery method, which solves the technical problem that an anchor rod pushing device cannot be directly aligned with the anchor rod when the anchor rod trolley takes the anchor rod from the anchor rod storage.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is:

[0005] An anchor rod storage assembly of an anchor rod trolley includes a support, an anchor rod storage, and an anchor rod pushing device. The support is connected to the anchor rod trolley, and the two ends of the support are rotatably connected to a swing frame 1 and a swing frame 2 respectively. The anchor rod storage is fixedly installed on the support, and a pushing beam is installed on the swing frame 1 and the swing frame 2. The anchor rod pushing device is slidably installed on the pushing beam. The anchor rod storage includes a plurality of anchor rods arranged in a circle, and each anchor rod can rotate around the arrangement center and align with the anchor rod pushing device.

[0006] Specifically, a shaft is rotatably provided on the support, and the swing frame 1 and the swing frame 2 are fixedly connected to the two ends of the shaft respectively. A swing cylinder is also provided on the support, and the stroke end of the swing cylinder is hinged to the swing frame 1.

[0007] Specifically, the anchor rod library is fixed on the support through a fixing bracket.

[0008] Specifically, the anchor rod library includes a fixed rod, a rotary drive device, a rotating rod, an anchor rod bracket and an anchor rod baffle. The fixed rod is fixed to the support through the fixed bracket, the rotary drive device is installed on the fixed rod through a connecting plate, the output end of the rotary drive device is connected to the rotating rod, the anchor rod bracket is fixedly installed on the rotating rod, and multiple anchor rods are clamped on the anchor rod bracket.

[0009] Specifically, the anchor rod baffle is fixedly arranged on the fixing rod and is located at the tail end of the anchor rod. The anchor rod baffle is provided with a notch, and the position of the notch is facing the moving direction of the anchor rod pushing device.

[0010] Specifically, the anchor rod bracket includes a base, a spring clip, a pressure block and a fastener. The base is fixed on the rotating rod. The base is a polygon with a circumscribed circle. Several spring clips are evenly distributed on the edge of the base. The spring clips are fixed to the base through the pressure block and fasteners.

[0011] Specifically, after the spring clip is aligned with the anchor rod pushing device, the symmetry center line of the spring clip is tangent to a circle with the axis as the center and the radius from the axis to the center of the anchor rod pushing device.

[0012] The push beam is provided with an anchor rod clamping mechanism, and the anchor rod clamping mechanism is a clamping claw that can clamp the anchor rod.

[0013] A method for feeding anchor rods to an anchor rod storage assembly of an anchor rod trolley comprises the following steps:

[0014] S1: After the anchor trolley finishes drilling the anchor hole, the swing cylinder starts and drives the swing frame 1 and the swing frame 2 to swing around the axis, thereby driving the push beam and the anchor pushing device to swing and approach the anchor warehouse;

[0015] S2, the rotation drive device drives the rotating rod, which in turn drives the anchor rod holder fixed on the rotating rod to rotate, so that the anchor rod clamped on the anchor rod holder is aligned with the anchor rod pushing device at the notch position of the anchor rod baffle;

[0016] S3, the anchor rod pushing device is docked with the anchor rod, the anchor rod clamping mechanism clamps the front end of the anchor rod, the rotary drive device rotates slightly, and the anchor rod is released from the spring clip;

[0017] S4, the anchor rod pushing device sends the anchor rod out along the pushing beam.

[0018] Based on the above technical solution, the following technical effects can be produced:

[0019] 1. The present invention controls the stroke of the swing cylinder to fix the anchor rod pushing device on the swing frame at the same position. Each time the anchor rod depot rotates at the same angle, the anchor rod is aligned with the anchor rod pushing device. The symmetrical center line of the spring clip that clamps the anchor rod is tangent to a circle formed with the axis as the center and the axis to the center of the anchor rod pushing device as the radius. When the anchor rod depot rotates again, the elastic deformation of the spring clip allows the anchor rod clamped by the clamping mechanism and engaged with the anchor rod pushing device to be separated from the anchor rod depot. This allows the anchor rod to align with the anchor rod pushing device after deflection, eliminating the need for a special anchor rod grabbing device, thereby simplifying the structure and simplifying the operation.

[0020] 2. The anchor rod depot of the present invention is provided with an anchor rod baffle to prevent the spring clip from deforming and causing the anchor rod to be unstable and fall off. BRIEF DESCRIPTION OF THE DRAWINGS

A swing cylinder 8 is also provided on the support 1, and the stroke end of the swing cylinder 8 is hinged to the swing frame 1 6.

[0035] Optionally or preferably, the anchor rod library 2 is fixed on the support 1 via a fixing bracket 10 .

[0037] An optional or preferred solution is that the anchor baffle 21 is fixed on the fixing rod 12 and is located at the tail end of the anchor rod 9. The anchor baffle 21 is provided with a notch, and the notch is located opposite to the travel direction of the anchor pushing device 3. The anchor rod warehouse 2 uses the anchor baffle 21 to limit the loosening and falling of the anchor rod.

[0038] An optional or preferred solution is that the anchor rod bracket 15 includes a base 17, a spring clip 18, a pressure block 19 and a fastener 20. The base 17 is fixed on the rotating rod 14. The base 17 is a polygon with a circumscribed circle. Several spring clips 18 are evenly distributed on the edge of the base 17. The spring clips 18 are fixed to the base 17 by the pressure block 19 and the fastener 20.

[0039] For optional or preferred options, see Figure 6 After the spring clip 18 is aligned with the anchor rod pushing device 3, the symmetry center line of the spring clip 18 is tangent to a circle with the axis 11 as the center and the axis 11 to the center of the anchor rod pushing device 3 as the radius.

[0040] Optionally or preferably, the push beam 5 is provided with an anchor rod clamping mechanism 4 , and the anchor rod clamping mechanism 4 is a clamping claw that can clamp the anchor rod 9 .

[0041] A method for feeding anchor rods to an anchor rod storage assembly of an anchor rod trolley comprises the following steps:

[0042] S1, after the anchor trolley finishes drilling the anchor hole, the swing cylinder 8 is activated and drives the swing frame 1 6 and the swing frame 2 7 to swing around the axis 11, thereby driving the pushing beam 5 and the anchor pushing device 3 to swing and approach the anchor warehouse 2;

[0043] S2, the rotation drive device 13 drives the rotating rod 14, which in turn drives the anchor rod holder 15 fixed to the rotating rod 14 to rotate, so that the anchor rod 9 clamped on the anchor rod holder 15 is aligned with the anchor rod pushing device 3 at the notch position of the anchor rod baffle 21;

[0044] S3, the anchor rod pushing device 3 completes docking with the anchor rod 9, the anchor rod clamping mechanism 4 clamps the front end of the anchor rod 9, the rotary drive device 13 rotates slightly, and the anchor rod 9 is disengaged from the spring clip 18;

[0045] S4, the anchor rod pushing device 3 sends the anchor rod 9 along the pushing beam 5.

[0046] The working principle of the anchor storage assembly of the anchor trolley provided by the present invention is as follows:

[0047] By setting the telescopic stroke of the swing cylinder 8 to be constant, the swing frame 16 and the swing frame 7 each rotate about the axis 11 at a constant angle, thereby ensuring that the anchor rod pushing device 3 on the pushing beam 5 swings at a constant angle. By designing the anchor rod holder 15 of a suitable size and according to the number of anchor rods 9 supported by the anchor rod holder 15, the rotation angle of the rotary drive device is the same each time, so that the anchor rod 9 is aligned with the anchor rod pushing device 3. At the same time, the symmetric centerline of the spring clip 18 holding the anchor rod 9 is tangent to the circle formed by the axis 11 as the center and the axis 11 and the center of the anchor rod pushing device 3 as the radius. When the anchor rod holder 15 is driven to rotate again, the elastic deformation of the spring clip 18 allows the anchor rod 9, which is clamped by the clamping mechanism 4 and engaged with the anchor rod pushing device 3, to be released from the anchor rod storage 2 and then delivered by the anchor rod pushing device 3 along the pushing beam 5. This ensures that the anchor rod is aligned with the anchor rod pushing device after deflection, eliminates the need for a dedicated anchor rod grabbing device, and achieves a simplified structure and easy operation.
