For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] During the construction process of mines and tunnels, it usually involves operations such as bolt operations and drilling operations, and such operations usually require a propulsion device to complete. However, the tensioning mechanism in the existing propulsion device has a complex structure and high cost, is not convenient to adjust, and the tensioning effect is not ideal after adjustment.

[0029] Based on the above problems, the present invention provides an anchor trolley, which is applied to fields such as mines and tunnel engineering. The anchor trolley includes an anchor operation device, and the anchor operation device can be used for drilling operations, grouting operations, and anchor operations, etc., with high operation efficiency.

[0030] Please refer to Figure 1 , the anchor operation device 1 provided by the present invention is applied to construction operation fields such as mines and tunnels. The anchor operation device 1 includes a propulsion beam assembly 11 and a tensioning mechanism 10, and the tensioning mechanism 10 is arranged at the end of the propulsion beam assembly 11.

[0031] In this embodiment, the anchor operation device 1 further includes a drilling mechanism and an anchor mechanism, etc. The drilling mechanism and the anchor mechanism are both arranged on the propulsion beam assembly 11, and drilling operations and anchor driving operations can be realized through the drilling mechanism, the anchor mechanism, and the propulsion beam assembly 11.

[0032] The tensioning mechanism 10 is arranged at one end of the propulsion beam assembly 11. The tensioning mechanism 10 and the propulsion beam assembly 11 are connected by a steel wire rope. The tensioning mechanism 10 is used to tension the steel wire rope, so as to improve the stability and reliability of the anchor operation device 1 during the reciprocating propulsion operation of the drilling mechanism and the anchor mechanism, and avoid fatigue damage of components such as oil cylinders due to vibration or swinging. Therefore, the service life of the anchor operation device 1 is effectively extended.

[0033] Specifically, please refer to Figure 2 and Figure 3, the tensioning mechanism 10 includes a pulley mounting member 100, a wire rope pulley 200, a propulsion beam connecting member 300, an adjusting member 400, and a fastening member 500.

[0034] Among them, the pulley mounting member 100 is arranged on the guide rail 900, and relative displacement with the propulsion beam connecting member 300 is realized through the guide rail 900; the adjusting member 400 is used to drive the displacement of the pulley mounting member 100.

[0035] In this embodiment, the propulsion beam connecting member 300 is used to connect with the propulsion beam assembly 11, and the pulley mounting member 100 is used to mount the wire rope pulley 200 to wind the wire rope connected with the propulsion beam assembly 11; and the pulley mounting member 100 can approach or move away from the propulsion beam connecting member 300 through the guide rail 900. Therefore, by driving the pulley mounting member 100 to displace relative to the propulsion beam connecting member 300 through the adjusting member 400, that is, driving the pulley mounting member 100 to approach or move away from the propulsion beam assembly 11, the distance between the propulsion beam connecting member 300 and the pulley mounting member 100 can be adjusted to a suitable distance to avoid the wire rope from being too tight or too loose, so as to enable the wire rope to rotate smoothly around the pulley mounting member 100, thus effectively improving the stability and reliability of the operation of the propulsion beam assembly 11.

[0036] Specifically, one end of the adjusting member 400 is connected to the pulley mounting member 100, and the other end is movably connected to the propulsion beam connecting member 300. Of course, in other embodiments of the present utility model, one end of the adjusting member 400 can also be connected to the propulsion beam connecting member 300, and the other end is movably connected to the pulley mounting member 100, as long as the adjusting member 400 can drive the displacement of the pulley mounting member 100, which is not specifically limited herein.

[0037] One end of the guide rail 900 is connected to the pulley mounting member 100, and the other end is used for sliding cooperation with the propulsion beam assembly 11. Of course, in other embodiments of the present utility model, one end of the guide rail 900 can also be used to connect with the propulsion beam assembly 11, and the other end is used for sliding cooperation with the pulley mounting member 100, as long as the pulley mounting member 100 can realize relative displacement with the propulsion beam connecting member 300 through the guide rail 900, which is not specifically limited herein.

[0038] Furthermore, the wire rope pulley 200 is movably arranged on the pulley mounting member 100, and the wire rope pulley 200 is used for winding the wire rope; the propulsion beam connecting member 300 is used to connect with the propulsion beam assembly 11; one end of the adjusting member 400 is connected to the pulley mounting member 100, and the other end is movably connected to the propulsion beam connecting member 300; the fastening member 500 is arranged on the adjusting member 400 and is used for fixed cooperation with the propulsion beam connecting member 300.

[0039] In this embodiment, one end of the wire rope is connected to the propulsion beam assembly 11, and the other end is wound around the wire rope pulley 200. By moving the adjusting member 400 relative to the propulsion beam connecting member 300, the distance between the propulsion beam connecting member 300 and the pulley mounting member 100 is adjusted. Therefore, the adjusting member 400 adjusts the distance between the propulsion beam connecting member 300 and the pulley mounting member 100 to an appropriate distance, avoiding the wire rope from being too tight or too loose, so that the wire rope can rotate smoothly around the wire rope pulley 200, and effectively improving the stability and reliability of the operation of the propulsion beam assembly 11.

[0040] It can be seen that the tensioning mechanism 10 provided by the present utility model has a simple structure, low cost and is convenient to adjust. After adjustment, the stability and reliability of the operation of the propulsion beam assembly 11 can be effectively improved.

[0041] Furthermore, the tensioning mechanism 10 further includes a wire rope baffle 600. The wire rope baffle 600 is arranged on the pulley mounting member 100, and the wire rope baffle 600 is arranged on the side of the pulley mounting member 100 away from the propulsion beam connecting member 300. The wire rope baffle 600 is used to prevent the wire rope from falling off the wire rope pulley 200.

[0042] In this embodiment, by arranging the wire rope baffle 600 on the pulley mounting member 100, the wire rope baffle 600 can play a blocking role on the wire rope, thereby effectively preventing the wire rope from falling out of the wire rope pulley 200, and thus effectively improving the structural stability of the tensioning mechanism 10.

[0043] Furthermore, the wire rope baffle 600 is perpendicularly arranged with respect to the wire rope pulley 200, and there is a gap between the wire rope baffle 600 and the edge of the wire rope pulley 200.

[0044] In this embodiment, the steel plate is perpendicularly arranged with respect to the plane where the wire rope pulley 200 is located, and there is a gap between the wire rope baffle 600 and the edge of the wire rope pulley 200. On the one hand, this can avoid the direct contact between the wire rope baffle 600 and the wire rope pulley 200, thereby avoiding the wire rope pulley 200 from being stuck or damaged. On the other hand, the gap between the baffle and the wire rope pulley 200 also provides a winding space for the wire rope, ensuring that the wire rope can be wound around the edge of the wire rope pulley 200.

[0045] Furthermore, a groove 210 is arranged on the outer peripheral wall of the wire rope pulley 200. The groove 210 is used to accommodate the wire rope, and the wire rope baffle 600 is correspondingly arranged with the groove 210.

[0046] In this embodiment, by providing a groove 210 on the outer peripheral wall of the wire rope pulley 200, the wire rope is wound in the groove 210, and the side wall of the groove 210 can also restrict the wire rope to prevent the wire rope from detaching from the wire rope pulley 200, thereby further improving the stability of the tensioning mechanism 10.

[0047] Further, the tensioning mechanism 10 further includes an end plate 700, and the end plate 700 is connected to a side of the wire rope baffle 600 away from the pulley mounting member 100.

[0048] In this embodiment, by providing an end plate 700 on the pulley mounting member 100, the end plate 700 is connected to the propulsion beam connecting member 300, and the pulley mounting member 100 is movably disposed between the end plate 700 and the propulsion beam connecting member 300, that is, the end plate 700 is located on a side of the pulley mounting member 100 away from the wire rope baffle 600, so that the pulley mounting member 100 and the wire rope baffle 600 are stably and firmly mounted, further improving the structural stability of the tensioning mechanism 10.

[0049] Further, the tensioning mechanism 10 further includes a plurality of connecting rods 800, and the end plate 700 and the propulsion beam connecting member 300 are connected by the plurality of connecting rods 800.

[0050] In this embodiment, by providing a plurality of connecting rods 800 between the end plate 700 and the propulsion beam connecting member 300 and arranging the plurality of connecting rods 800 in parallel, the stability of the end plate 700 and the propulsion beam connecting member 300 can be improved by the plurality of connecting rods 800.

[0051] Further, the tensioning mechanism 10 further includes a guide rail 900 and a slider 1000. The slider 1000 is used to be disposed on the propulsion beam assembly 11, and the guide rail 900 is connected to the propulsion beam connecting member 300 and slidably cooperates with the slider 1000.

[0052] In this embodiment, the slider 1000 is fixedly mounted on the propulsion beam assembly 11, one end of the guide rail 900 is fixedly connected to the pulley mounting member 100, and the other end slidably cooperates with the slider 1000; it can be understood that the slide rail extends along the length direction of the propulsion beam assembly 11, so as to play a guiding role for the relative movement of the pulley mounting member 100 and the propulsion beam connecting member 300 through the sliding cooperation of the guide rail 900 and the slider 1000, ensuring the relative movement of the pulley mounting member 100 and the propulsion beam connecting member 300 along the extending direction of the guide rail 900.

[0053] Further, the number of the fastening members 500 is two. The adjusting member 400 is in threaded cooperation with the propulsion beam connecting member 300. Both of the two fastening members 500 are sleeved on the adjusting member 400 and in threaded cooperation with the adjusting member 400, and the two fastening members 500 respectively abut against two sides of the propulsion beam connecting member 300.

[0054] In the present embodiment, by providing two fasteners 500 on the adjusting member 400, after the adjustment of the adjusting member 400 is completed, the two fasteners 500 respectively abut against both sides of the propulsion beam connecting member 300, thereby playing a fixing role.

[0055] Optionally, the adjusting member 400 is a screw rod and the fastener 500 is a nut. Of course, in other embodiments, the adjusting member 400 and the fastener 500 may also be other components, as long as the above functions can be achieved, and specific limitations are not made here.

[0056] Furthermore, the tensioning mechanism 10 further includes a pulley pin shaft 1100. The pulley pin shaft 1100 is arranged on the pulley mounting member 100, and the wire rope pulley 200 is rotatably arranged on the pulley pin shaft 1100.

[0057] In the present embodiment, by arranging the wire rope pulley 200 on the pulley pin shaft 1100, the wire rope pulley 200 can rotate relative to the pulley pin shaft 1100, so that the wire rope can smoothly rotate around the wire rope pulley 200, thereby ensuring the structural stability of the tensioning mechanism 10.

[0058] In summary, the present invention provides a tensioning mechanism 10 and an anchor rod working device 1. One end of the wire rope is connected to the propulsion beam assembly 11, and the other end is wound around the wire rope pulley 200; by moving the adjusting member 400 relative to the propulsion beam connecting member 300, the distance between the propulsion beam connecting member 300 and the pulley mounting member 100 is adjusted. Therefore, the distance between the propulsion beam connecting member 300 and the pulley mounting member 100 is adjusted to a suitable distance by the adjusting member 400, avoiding the wire rope from being too tight or too loose, so that the wire rope can smoothly rotate around the wire rope pulley 200, and effectively improving the stability and reliability of the operation of the propulsion beam assembly 11. It can be seen that the tensioning mechanism 10 provided by the present invention has a simple structure, low cost and is convenient to adjust. After adjustment, the stability and reliability of the operation of the propulsion beam assembly 11 can be effectively improved.
