Description

Technical Field

[0001] This utility model belongs to the technical field of anchor cable tensioning equipment for coal mine roadways, and particularly relates to a portable lifting device for the head of a roadway anchor cable tensioning machine. Background Technology

[0002] Anchor tensioners are the core equipment for tensioning and locking anchor cables. Their main function is to apply the designed tension to the anchor cable and lock it in place to ensure that the anchor cable plays a reinforcing and stabilizing role.

[0003] During anchor cable tightening, workers first need to climb a ladder while holding the jacking head (weighing approximately 20 kg). Then, the front end of the jacking head clamps the end of the anchor cable. The workers then release the jacking head and activate the anchor cable tensioner to tighten the jacking head onto the anchor cable. After tightening, the tensioner is closed, and the jacking head is released and falls freely. During this process, the jacking head falling freely after the tensioner is closed poses a risk of injury to workers near the equipment, and over time, this process can easily damage the jacking head. Utility Model Content

[0004] The purpose of this invention is to provide a portable lifting device for the head of a roadway anchor cable tensioning machine, so as to reduce the risk of anchor cable tightening process and improve the service life of the head.

[0005] The present invention adopts the following technical solution: a portable lifting device for the head of a roadway anchor cable tensioning machine, including a slide bar installed on the top of the roadway and aligned with the roadway direction, the slide bar being horizontally set and having several curved sections evenly spaced; The opening at each bend faces upwards; A hook is hung on the sliding rod, and a fixed pulley is installed below the hook; It also includes a suspension rope, which is hung on a fixed pulley, and the two ends of the suspension rope are respectively equipped with a first hook and a second hook, which are used to hang the head of the anchor cable tensioning machine.

[0006] The beneficial effects of this utility model are: by connecting one end of the sling to the cannon head and the other end to the puller or the drum, the worker can avoid carrying the cannon head up the ladder, and the cannon head can be prevented from falling freely after the anchor cable is tightened, thus reducing the risk of the anchor cable tightening process and improving the service life of the cannon head.

[0009] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0010] This utility model discloses a portable lifting device for the head of a roadway anchor cable tensioning machine, such as... Figure 1 As shown, it includes a slide bar 40 installed on the top of the tunnel and aligned with the tunnel direction. The slide bar 40 is horizontally positioned and has several evenly spaced bends 41. The opening of each bend 41 faces upward. A hook 50 is hung on the slide bar 40, and a fixed pulley 60 is located below the hook 50. It also includes a suspension rope 70, which is hung on the fixed pulley 60. The two ends of the suspension rope 70 are respectively provided with a first hook 71 and a second hook 72. The first hook 71 and the second hook 72 are used to hang the head of the anchor cable tensioning machine.

[0011] This utility model connects one end of the sling 70 to the sling head, and the other end is pulled by the worker or connected to the drum 80. This can avoid the worker carrying the sling head up the ladder, and can also prevent the sling head from falling freely after the anchor cable is tightened. This reduces the risk of the anchor cable tightening process and improves the service life of the sling head.

[0012] To further reduce the workload of workers, this device also includes a drum 80, which is detachably installed on the support netting 20 on the side of the roadway 10. The drum 80 is connected to the first hook 71 / second hook 72. The hoisting rope 70 can be pulled by the drum 80, saving labor and effort.

[0013] More specifically, a connecting rope is fixedly installed on the drum 80, and the other end of the connecting rope has a third hook 81, which is used to connect with the first hook 71 / second hook 72. The connecting rope and the third hook 81 facilitate the connection between the drum 80 and the first hook 71 / second hook 72. The hook can also be designed as a male and female hook (or snap fastener), which is simple to connect and ensures that the two hooks will not detach after connection.

[0014] In one embodiment, the slide bar 40 is located in the middle of the tunnel 10 and is installed on the tunnel's support mesh via hooks or clips. The slide bar 40 can be made of steel bars and installed at the top of the tunnel by binding with wire or using hooks. This allows the blasting head to be easily hoisted to the top of the tunnel.

[0015] Furthermore, the curved portion 41 smoothly transitions to the straight portion of the connected slide rod 40, ensuring that the hook 50 slides smoothly on the slide rod 40.

[0016] The method of using this utility model is as follows: First, the processed slide bar 40 is installed on the support net 20 at the top of the roadway 10. During installation, the slide bar 40 is fixed at both ends to prevent the fixed hook or binding wire from affecting the sliding of the hook 50 on it. At the same time, the hook 50 is hung on the slide bar 40.

[0017] Next, move the hook 50 to the nearest bend 41 to the position where the gun head needs to be lifted. The bend 41 prevents the hook 50 from sliding back and forth during use.

[0018] Then, the drum 80 is secured to the support netting 20 on the side of the tunnel 10 using ropes or bolts. The hoisting rope 70 is then passed through the fixed pulley 60, with the first hook 71 at one end of the rope 70 hooked onto the inlet / outlet oil pipe of the blasting head, and the second hook 72 connected to the third hook 81. The drum 80 is then rotated to pull the hoisting rope 70, causing the blasting head hooked on the first hook 71 to slowly rise. When it reaches the predetermined height, workers climb the ladder, align the blasting head with the end of the anchor section 30 in the tunnel 10, and the operator below activates the anchor cable tensioner to clamp the end of the anchor cable 30 with the blasting head. The worker then climbs down the ladder, hooks the second hook 72 onto the nearby support netting 20, and activates the anchor cable tensioner to tighten the anchor cable 30 through the blasting head.

[0019] After the anchor cable 30 is tightened, the connection between the cannon head and the end of the anchor cable 30 is disconnected. The cannon head falls freely under the action of gravity. However, since the cannon head is connected to the first hook 71, it is hooked by the first hook 72 when it falls to a certain extent. Then, the second hook 72 is connected to the drum 80, and the cannon head is slowly lowered through the drum 80 until the staff removes the first hook 71 from the cannon head.

[0020] When it is necessary to tighten the anchor cable of the next section of the tunnel 10, simply pull the first hook 71 and the second hook 72 and swing them back and forth. The lifting rope 70 will pull the hook 50 out of the bend and move it to the next bend. Then repeat the above process.
