Description

Technical Field

[0001] The utility model relates to a push-pull anchor cutter. Background Art

[0002] There are huge safety hazards and high labor costs in the anchor removal and roof removal work in underground fully mechanized mining faces in coal mines across the country. Now, almost all coal mines across the country use the most primitive manual anchor remover to carry out anchor removal and roof removal operations, and some use explosive blasting to remove the roof. When using the anchor remover to remove the roof, 2-3 workers are required to hold the anchor removal jack by hand, standing on a temporary construction scaffolding. After several people hold the anchor removal jack together and connect it to the anchor, they direct the ground staff to manually pressurize the power pump, and then take out the anchor after the anchor is loosened. After the anchor removal jack is sent back to the ground, the workers return to the ground to dismantle and transfer the scaffolding. In order to remove one or two anchors, it takes at least 2-3 hours to complete this set of processes. The mine has to spend huge labor costs over the years to complete the task. Moreover, after the anchor is removed, the rock and coal blocks on the top of the tunnel are likely to collapse at any time, and the safety of personnel cannot be guaranteed at all. Most anchors cannot be effectively removed. Some coal mines use explosives to remove the roof, which has a greater risk of safety accidents. If the anchors are not removed, the fully mechanized mining tunnel will fall into disrepair over time, and most of the anchors will rust and fall off, causing the entire tunnel to collapse. The harmful gases in the collapsed tunnel will all flow into the production working face, and workers on the working face will be poisoned and suffocated after inhaling the harmful gases, which will harm their health. Therefore, any safety accident will have catastrophic consequences for coal mine safety production. Summary of the Invention

DETAILED DESCRIPTION

[0014] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 、 2As shown in Figure 3, a push-pull anchor cutter in this embodiment includes a machine base 1. A longitudinal groove and a transverse groove are provided at the center of the top of the machine base 1 to form a cross-shaped storage groove. Two horizontally arranged knife seats 4 are symmetrically arranged in the transverse groove, and knife heads 5 are provided on the opposite surfaces of the knife seats 4. Push-pull arms 2 are provided on the left and right sides of the machine base 1 respectively. The upper and middle parts of the push-pull arms 2 are hinged to the machine base 1 respectively, and the top ends of the push-pull arms 2 are connected to the knife seats 4 on the corresponding sides through connecting plates 7. A vertically arranged cutting cylinder 3 is provided at the bottom of the machine base 1, and a cylinder connecting plate is provided at the protruding end of the cutting cylinder 3. The bottom ends of the push-pull arms 2 are connected to the cylinder connecting plate 8 through connecting rod groups. The anchor is arranged in the storage groove and between the two cutting heads. The cutting cylinder 3 drives the cylinder connecting plate 8 to move up and down, driving the connecting rod group to swing, so that the push-pull arm 2 rotates around the hinge point. The rotation of the push-pull arm 2 pushes the knife seat 4 to move in the machine base 1, and the two cutting heads 5 approach each other to cut the anchor; or move away from each other.

[0016] The top of the machine base 1 is symmetrically covered with a top plate 6, and a guide groove 10 is provided on the bottom surface of the top plate 6. A guide block 11 is provided on the top surface of the tool holder 4. The guide block 11 matches the guide groove 10 so that the guide block is arranged in the slot and plays a guiding role when the tool holder moves in the machine base.

[0017] Any connecting rod group includes two connecting rods 9, which are symmetrically arranged on both sides of the cylinder connecting plate. One end of the connecting rod is connected to the cylinder connecting plate through a pin, and the other end of the connecting rod is connected to the bottom of the push-pull arm.

[0018] The extension and retraction of the cutting cylinder's extension rod drives the synchronous movement of the cylinder connecting plate, causing the connecting rod group to drive the push-pull arm to rotate around the hinge point, driving the knife seat to move along the machine base, and the two knife heads to cut the anchor cable. This application has a simple structure and is easy to operate, avoiding the bending and tangling of the anchor cable when withdrawing the anchor.

[0019] The cutter can be installed on an operating platform with a multi-dimensional rotating mechanism, so that the cutter can rotate in the X\Y\Z axis direction, and can cut the anchor cables and anchors with various inclination angles of the mine roof according to the unevenness of the mine roof.

[0020] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
