Description

TECHNICAL FIELD

[0001] The utility model belongs to the processing technical field of grouting anchor rod especially relates to a grouting anchor rod automatic feeding device. BACKGROUND

[0002] Grouting anchor rod is a kind of device that can inject concrete slurry and open groove in engineering construction frequently. The main structure of grouting anchor rod includes anchor rod part and drill bit installed at the end of anchor rod part, and in working process, operator installs grouting anchor rod into drilling equipment and drives anchor rod into natural structure such as slope and roadway. The stability of structure is realized by the anchoring effect of anchor rod.

[0003] Meanwhile, drill bit at the end of anchor rod is used to open groove. In the production and processing of grouting anchor rod, anchor rod is formed by cutting anchor rod blank in sections, so in cutting process, anchor rod needs to be pushed onto cutting equipment for cutting. In pushing process, because the length of anchor rod blank is large and the weight is high, anchor rod needs to be kept in suspended state in cutting process.

[0004] The current practice is to support anchor rod on cushion block and manually push anchor rod in sections to cutting wheel of cutting equipment for cutting. Firstly, the friction between anchor rod blank and cushion block is high in pushing process, so it is difficult to push, and secondly, when cutting wheel touches anchor rod blank, the tail of anchor rod blank is prone to be raised, and anchor rod blank is unstable in cutting process, so the cutting precision is not high in cutting process, such as the defect that the cutting mouth position is not neat.

[0005] Based on the above defects, the production efficiency is not high in anchor rod production process, and the waste rate of anchor rod cutting in production process is high. INVENTION CONTENTS

Under the driving of the motor, the lead screw rotates and drives the pushing arm to move, and the anchor rod blank is continuously pushed to move in the forward direction during the movement of the pushing arm.

[0025] This method enables the anchor bolt blank to be pushed in a labor-saving, flexible, and convenient manner during the cutting process. It solves the technical problem of difficulty in pushing and cutting long anchor bolt blanks into segments during processing.

[0038] Example 1

[0039] like Figures 1-5 As shown, an automatic feeding device for grouting anchor bolts includes an anchor bolt feeding mechanism, which automatically pushes anchor bolt blanks of a relatively long length.

[0040] Specifically, the anchor bolt feeding mechanism includes a pusher track 1. In order to limit the anchor bolt blank, the top two sides of the pusher track 1 are respectively fixedly connected to the limiting guide rails 11. The inner sidewall of the limiting guide rail 11 is an inclined slope (that is, the longitudinal cross-sectional shape of the limiting guide rail 11 is trapezoidal), thus forming a V-shaped pusher structure.

[0041] A pushing structure with pushing anchor bolt blanks is assembled and connected on the pushing track 1.

[0042] Specifically, a long sliding opening is provided at the center of the push track 1, and the push structure includes a push arm 21 that is slidably connected within the long sliding opening. The push arm 21 is rectangular in shape.

[0043] Meanwhile, the pushing structure further comprises a screw rod 23 threadedly connected to the lower end of the pushing arm 21; the screw rod 23 is rotationally connected to the pushing track 1, specifically, mounting holes are formed in the front and rear sidewalls of the long sliding port, bearings are installed in the mounting holes in the same manner as the prior art, and the two ends of the screw rod 23 are rotationally connected to the bearings.

[0044] Meanwhile, a motor 22 for driving the screw rod 23 to rotate is installed at the rear end of the screw rod 23 (in the prior art, the motor 22 is fixed to the rear sidewall of the track, and the output shaft is fixedly installed on the screw rod 23 through a coupling or the like).

[0045] Meanwhile, in order to increase the flexibility of the pushing structure in pushing the anchor rod blank, the bottom of the pushing arm 21 is fixedly connected with a sliding roller structure, which comprises a sliding roller rod 24 fixedly connected with the pushing arm 21, and sliding track wheels 25 rotationally connected to the two ends of the sliding roller rod 24.

[0046] The bottom of the pushing track 1 is fixedly connected with lower guide rails 12 (longitudinal cross-section shape L) on both sides, and the sliding track wheels 25 roll on the lower guide rails 12.

[0047] During operation, the anchor rod blank is placed in the pushing track 1, and under the limiting of the limiting guide rail 11, the anchor rod blank is limited between the pushing track 1 and the limiting guide rail 11 (the diameter of the anchor rod blank is greater than the width of the long sliding port).

[0048] Subsequently, under the driving of the motor, the screw rod 23 rotates and drives the pushing arm 21 to move, and in the moving process of the pushing arm 21, the anchor rod blank is continuously pushed to move in the front direction.

[0049] In this way, the anchor rod blank is pushed in a labor-saving, flexible and convenient manner during the cutting process. This method solves the technical defect that it is difficult to push the rod blank to cut it in sections during the cutting process of the long anchor rod blank.

[0050] The discharge end of the pushing track 1 is fixedly connected with a guide structure, which comprises a guide plate 3 fixedly connected to the discharge end of the pushing track 1, and the guide plate 3 is provided with guide holes 31. In this way, the anchor rod blank is penetrated from the guide holes 31, thereby ensuring the posture of the anchor rod after discharging and facilitating accurate cutting.

[0051] Embodiment 2

[0052] As shown in Figures 1-5 the structure of embodiment 1, the discharge end of the guide structure is provided with an anchor rod blank pulling structure. During operation, the blank is pulled into the cutting equipment with the assistance of the anchor rod blank pulling structure, and in particular, the length of the anchor rod blank pulled out can be adjusted with the assistance of the anchor rod blank pulling structure, thereby facilitating accurate cutting length.

[0053] Specifically, the anchor bolt blank pulling structure includes a pair of pulling wheels, each of which is equipped with a drive motor (the drive motor is fixed on the mounting bracket described below). The anchor bolt blank is pulled by the frictional power of the pulling wheels.

[0054] Specifically, mounting brackets 4 are fixedly connected to the front and rear sides of the guide plate, and first pull wheels 51 and second pull wheels 52, symmetrically arranged vertically, are rotatably connected between the mounting brackets 4. Both the first pull wheels 51 and the second pull wheels 52 are made of elastic rubber, and are dumbbell-shaped.

[0055] During operation, the anchor bolt passes through the gap in the V-shaped structure between the first pulling wheel 51 and the second pulling wheel 52. Driven by the drive motor 53, the first pulling wheel 51 and the second pulling wheel 52 elastically compress the anchor bolt blank, dragging it along. This method allows for precise control of the dragging length and enables coordination with the cutting equipment to adjust the cutting position of the anchor bolt blank. This method also facilitates flexible adjustment of the relative position between the anchor bolt blank and the cutting equipment during the cutting process.

[0056] After the cutting is completed, the above-mentioned pushing structure continues to push the anchor bolt blank until the anchor bolt blank extends between the first pulling wheel 51 and the second pulling wheel 52. Then the motor 22 is turned off (the lead screw 23 stops rotating), and the first pulling wheel 51 and the second pulling wheel 52 work to drag the anchor bolt blank.

[0057] Example 3

[0058] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 2, in order to prevent the anchor rod blank from warping during the cutting process, an anchor rod positioning structure is installed at the discharge end of the above-mentioned anchor rod blank pulling structure.

[0059] Specifically, the anchor bolt positioning structure includes positioning cylinders 6 fixedly connected to the top of the mounting frame 4 and positioning cylinders 6 fixedly connected to the bottom of the mounting frame 4. During the positioning process, the piston rods of the positioning cylinders 6 press and position themselves on the top and bottom of the anchor bolt blank. At the same time, cylinder supports for fixing and installing the positioning cylinders 6 are fixedly connected between the top and bottom of the mounting frame 4.

[0060] By using the positioning cylinder 6 to squeeze and position the anchor rod blank from the top and bottom, the anchor rod remains stationary during the cutting process, thereby increasing the cutting accuracy.

[0061] Of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
