Description

Technical Field

[0001] This invention relates to the field of anchor cable support equipment technology; specifically, this invention relates to a coal mine anchor cable support device. Background Technology

[0002] In anchor cable support operations, anchor cable drilling is a relatively time-consuming and labor-intensive construction step. Existing anchor cable drilling operations, due to the obstruction of the anchor hole inner wall and other uncertainties, combined with the uncertainty of the mining environment, mainly rely on manual labor. In actual manual anchor cable drilling operations, workers need to pull or lift the anchor cable while slowly inserting it into the anchor hole. Furthermore, if obstruction is encountered and insertion is not possible, forced insertion is not allowed; the anchor cable must be pulled back and wiggled from side to side before re-inserting. Although manual anchor cable drilling is time-consuming and labor-intensive, the ability to adjust the anchor cable based on the obstruction during drilling ensures effective insertion. Therefore, improving anchor cable support equipment to reduce manual labor intensity and ensure operational safety while maintaining the advantage of timely adjustments based on the anchor cable drilling situation is extremely important and also a challenge in improving anchor cable support equipment.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This application provides a coal mine anchor cable support device for drilling operations in roadway anchor cable support. Specifically, it is used in drilling operations to support and stably push the anchor cable, reducing the labor intensity of manually pulling and lifting the anchor cable. Especially when drilling anchor cables into the roadway roof, it allows workers to release the anchor cable with their hands without causing the anchor cable to pull back and fall from the anchor hole, reducing construction difficulty and improving construction safety. In particular, when equipped with a lifting work platform, the anchor cable support device can be fixed on the lifting work platform for anchor cable support operations.

[0022] like Figures 1 to 10 As shown, the coal mine anchor cable support device of this application includes a platform 1, a pusher wheel 3, a pusher clamp 5, a barbed band 6, a front barbed pair 7, and a rear barbed pair 8.

[0023] Platform 1 has retractable support legs 2 rotatably mounted at both its front and rear ends. Platform 1 includes a plate body 1.1 and an arc-shaped track body 1.2. One arc-shaped track body 1.2 is provided at each of the front and rear ends of the plate body 1.1. The plate body 1.1 is rotatably mounted on the arc-shaped track body 1.2, and the support legs 2 are mounted on the two arc-shaped track bodies 1.2. By rotating the plate body 1.1 on the arc-shaped track body 1.2, the anchor cable can be rotated left and right around its center axis during anchor cable drilling, reducing the friction between the anchor cable and the anchor hole or mitigating the resistance effect, thus facilitating the anchor cable drilling operation.

[0024] The telescopic design of the support leg 2 allows for adjustment of the device's height during anchor cable drilling operations on the roadway sidewall, making it suitable for anchor cable drilling operations at different heights.

[0025] The support leg 2 is designed to rotate to adjust the tilt angle of the platform 1. Specifically, a pin is installed at the top of the support leg 2, a positioning plate is installed on the arc-shaped track section 1.2, and a ring of pin holes is provided around the circumference of the positioning plate. The support leg 2 is locked by inserting the pin into the pin holes. Combined with the telescopic adjustment of the front and rear support legs 2, the pitch angle of the platform 1 can be adjusted, making it better suited for anchor insertion operations in inclined anchor holes.

[0026] To improve the angular positioning effect of the pin-fitting hole on the support leg 2 and platform 1, the pin is a bolt, and its thread is installed on the top of the support leg 2. The support leg 2 is configured with two threaded sleeves, and its length can be adjusted by rotation.

[0027] Two push wheels 3 are positioned opposite each other at the front end of the top of the platform 1, forming a push channel 4 for the anchor cable between the two push wheels 3. Both push wheels 3 are concave in the middle and are respectively clamped on both sides of the anchor cable. When pushing the anchor cable, the push wheels 3 rotate to feed the anchor cable into the anchor hole.

[0028] The front and rear ends of the slide block 5.1 form "U"-shaped through holes 9, and the through holes 9 are concentric with the push channel 4. The anchor cable passes through the through holes 9. The through holes 9 can work with the push channel 4 to limit the anchor cable at two points, so that the anchor cable is in a taut state. When the clamping plate 5.2 holds the anchor cable, there is no need to push the anchor cable, thereby reducing the resistance formed by the anchor cable blocking the clamping plate 5.2 when the handle 5.3 is manually pressed down, making it easier to operate.

[0029] The push clamp 5 includes a slide 5.1, a clamping plate 5.2 and a handle 5.3. The slide 5.1 is slidably mounted on the platform 1. There is one clamping plate 5.2 on each side of the top of the slide 5.1. The handle 5.3 is located at the top of the slide 5.1. The handle 5.3 drives the bottom ends of the two clamping plates 5.2 to rotate relative to each other and clamp the anchor cable by moving downward.

[0030] When pushing the anchor cable, the worker first presses down the handle 5.3 to clamp the anchor cable with the clamping plate 5.2, then pushes the handle 5.3 forward, pushing the anchor cable forward with the entire clamping angle. After the pusher 5 completes its stroke, the worker pulls the handle 5.3 upward to release the clamping force of the clamping plate 5.2 on the anchor cable, and then pulls the pusher 5 back to its initial position, thus achieving segmented pushing and drilling of the anchor cable.

[0031] Two spiked belts 6 are installed inside the platform 1, each connected to a push wheel 3, to drive the two push wheels 3 to rotate synchronously in opposite directions. Both ends of the spiked belt 6 are equipped with pulleys, which are rotatably mounted on the platform 1. The two pulleys at the front end are coaxially arranged with the two push wheels 3. When the spiked belt 6 rotates, it drives the pulleys to rotate, and the front pulleys drive the push wheels 3 to rotate, allowing the push wheels 3 to work in conjunction with the push clamp 5 to push the anchor cable at two points simultaneously. At this time, the push wheels 3 ensure that the anchor cable is taut near the anchor hole, making it easier for the anchor cable to enter the anchor hole. Simultaneously, the synchronized and coordinated movement of the push wheels 3 and the push clamp 5 ensures that the anchor cable between them remains taut, preventing anchor cable deformation that could hinder effective pushing.

[0032] The front spike pair 7 is positioned between the front ends of the straight sections of the two spike bands 6 that are close to each other. It includes two front spike plates 7.1 that are slidably installed within the platform 1, capable of locking the push wheel 3 in reverse. During the pushing of the anchor cable, the front spike pair 7 locks the push wheel 3 in reverse in real time. By utilizing the clamping action of the push wheel 3 on the anchor cable, it prevents the anchor cable from being pulled out of the anchor hole in reverse. Thus, there is no need for manual lifting of the anchor cable, reducing construction difficulty and improving safety.

[0033] The rear spike pair 8 includes two rear spike plates 8.1 slidably mounted on the bottom of the slide block 5.1. These plates can follow the displacement of the push clamp 5 and, when moving forward, can drive the push wheel 3 to rotate via the spike band 6 and push the anchor cable into the anchor hole. When pushing the anchor cable forward, the push clamp 5 is in a clamping state, at which time the two front spike plates 7.1 are engaged with the two spike bands 6 respectively.

[0034] Specifically, the front spike pair 7 also includes a front slider fixedly installed on the top of the front spike plate 7.1. A front sliding groove is provided on the platform 1, and the top of the front slider is slidably installed in the front sliding groove to realize the installation of the front spike plate 7.1.

[0035] The rear spike pair 8 also includes a rear slider fixedly installed on the top of the rear spike plate 8.1. The bottom of the slide block 5.1 is provided with a rear sliding groove, and the top of the rear slider is slidably installed in the rear sliding groove to realize the installation of the rear spike plate 8.1.

[0036] An extended spring is also connected between the two front spike plates 7.1 and the two rear spike plates 8.1 to provide force for the engagement of the spike band 6. The extended spring is compressed during the process of the front spike plates 7.1 and the rear spike plates 8.1 moving inward to disengage from the spike band 6.

[0037] In the coal mine anchor cable support device of this application, the pushing clamp 5 also includes a wedge block 5.4 and a pressure block 5.5.

[0038] Wedge blocks 5.4 are slidably mounted on both sides of the slide block 5.1. The side facing the clamping plate 5.2 is flat, and the side away from the clamping plate 5.2 is inclined. The clamping plate 5.2 is driven by displacement within the box to clamp the anchor cable. Pressure blocks 5.5 are vertically mounted on top of the slide block 5.1. When pressed down by the handle 5.3, they push the wedge blocks 5.4 inwards, pushing the clamping plate 5.2. When the handle 5.3 is pressed down, it presses down the pressure blocks 5.5. As the pressure blocks 5.5 pass over the inclined surface of the wedge blocks 5.4 from top to bottom, they push the wedge blocks 5.4 inwards. This pushes the clamping plate 5.2 inwards, causing the swing plate to rotate inwards and clamp the anchor cable.

[0039] In order to achieve the effect of pulling back when the anchor cable is blocked by the hole wall during the anchor cable drilling process, the front thorn pair 7 needs to be able to automatically determine whether the reverse action of the push clamp 5 is to reset and push the anchor cable again, or whether the anchor cable needs to be pulled back to continue pushing, so as to unlock the front thorn pair 6 automatically.

[0040] At this point, the push clamp 5 of this application also includes a ramp 5.6, a push rod 5.7, and a synchronization plate 5.8. The ramp 5.6 is fixedly installed on the top of the rear spike plate 8.1 and located inside the slide 5.1. The push rod 5.7 is inserted into the slide 5.1, and its top end is fixedly connected to the wedge block 5.4. The synchronization plate 5.8 is slidably installed on the platform 1, with its two ends passing through the front spike plate 7.1 and the rear spike plate 8.1 located on the same side, respectively. The handle 5.3, the wedge block 5.4, and the pressure block 5.5 can move synchronously on the slide 5.1 in the front-to-back direction, and when the push rod 5.7 moves backward in the clamping state of the anchor cable, the ramp 5.6 and the synchronization plate 5.8 cause both the front spike plate 7.1 and the rear spike plate 8.1 to disengage from the spike band 6.

[0041] The top of the slide block 5.1 is provided with a rectangular groove, and the insertion rod is located in the rectangular groove. The length direction of the rectangular groove is adapted to the front and back displacement of the insertion rod, and the width direction of the rectangular groove is adapted to the left and right position of the insertion rod.

[0042] When the clamping block holds the anchor cable, the sliding rod 5.11 is in its innermost position and located on the outer surface of the inner end of the inclined plate 5.6. When the clamping plate 5.2 moves backward while holding the anchor cable, the anchor cable cannot be pulled out of the anchor hole because the front shank 7.1 locks the barbed band 6. This allows the handle 5.3, wedge block 5.4, and pressure block 5.5 to move backward synchronously on the sliding block 5.1 in the front-back direction. At this time, as the sliding rod 5.11 moves from the inner end to the outer end of the inclined plate 5.6, it pushes the inclined plate 5.6 inward. The inclined plate 5.6 first causes the rear shank 8.1 to separate from the barbed band 6. Then, the inclined plate 5.6 continues to push the rear shank 8.1 inward. The rear shank 8.1 pushes the synchronizing plate 5.8 through the box, causing the front shank 7.1 to move inward and disengage from the barbed band 6. Thus, the barbed band 6 is unlocked.

[0043] During the subsequent backward displacement of the push clamp 5, the anchor cable will be pulled out of the anchor hole in the opposite direction. In addition, when the clamping plate 5.2 in the push clamp 5 returns in a relaxed state, due to the holding force of the extended spring on the rear ratchet plate 8.1, the slide rod 5.11 will be guided by the inclined plate 5.6 when it moves from the inner end to the outer end, causing the wedge block 5.4 to move outward as a whole. During this process, the ratchet band 6 will not be unlocked.

[0044] Therefore, after setting the push angle as described above, the machine can automatically determine whether to pull the anchor cable in the reverse direction without requiring any additional operation from the workers, and automatically control whether the spike belt 6 is locked or unlocked, and realize the locking and unlocking of the push wheel 3, which greatly facilitates the operation of workers and improves construction safety.

[0045] The front ratchet plate 7.1 and the rear ratchet plate 8.1 are respectively provided with a front through groove 7.2 and a rear through groove 8.2 for the end of the synchronization plate 5.8 to pass through. The difference between the width of the front through groove 7.2 and the thickness of the synchronization plate 5.8 is twice the travel distance of the front ratchet plate 7.1 when it is disengaged from the ratchet band 6. The difference between the width of the rear through groove 8.2 and the thickness of the synchronization plate 5.8 is three times the travel distance of the rear ratchet plate 8.1 when it is disengaged from the ratchet band 6.

[0046] Through the cooperation of the front through groove 7.2 and the rear through groove 8.2, the front spike plate 7.1 and the rear spike plate 8.1 will not be interfered with by the synchronization plate 5.8 when they are separating from and re-engaging with the spike band 6. Before the pusher clamp 5 clamps the anchor cable and pulls it out of the anchor hole in the opposite direction, during the process of the slide rod 5.11 pushing the inclined plate 5.6 inward, the rear spike plate 8.1 moves inward first to unlock the spike band 6. At this time, the outer inner wall of the rear through groove 8.2 contacts the synchronization plate 5.8, and the inner inner wall of the front through groove 7.2 contacts the synchronization plate 5.8. Therefore, as the rear spike plate 8.1 continues to move inward, it will push the synchronization plate 5.8 to move the front spike plate 7.1 inward, so that the front spike plate 7.1 disengages from the spike band 6.

[0047] In order to realize the control of the clamping plate 5.2 to clamp the cable anchor by pressing down the handle 5.3, the pushing fixture 5 further includes a sliding frame 5.9 and a lifting frame 5.10. The sliding frame 5.9 is slidably mounted on the sliding seat 5.1 in the front-back direction, and the wedge block 5.4 is restricted inside the bottom end of the sliding frame 5.9 in the front-back direction; the lifting frame 5.10 is mounted on the sliding frame 5.9 so as to be able to lift, and the pressing block 5.5 is fixed to the bottom end of the lifting frame 5.10; the handle 5.3 is mounted on the sliding frame 5.9 and can press down the lifting frame 5.10.

[0048] Furthermore, both the limiting frame and the lifting frame 5.10 are in an open-downward "C" shape, and the pushing fixture 5 further includes a sliding rod 5.1 and a return spring 5.12. The sliding rod 5.11 is fixedly arranged in the middle of the top of the limiting frame, the middle part of the lifting frame 5.10 is slidably sleeved outside the sliding rod 5.11, and the handle 5.3 is sleeved on the top end of the sliding rod 5.11; the return spring 5.12 is sleeved outside the sliding rod 5.11 and is located between the limiting frame and the lifting frame 5.10.

[0049] The pushing fixture 5 further includes a sliding groove 5.13 and a sliding block . The sliding groove 5.13 is in an "L" shape and is arranged on the surface of the sliding rod 5.11; the sliding block 5.14 is fixedly arranged on the inner wall surface of the handle 5.3 and can slide in the sliding groove 5.13.

[0050] By providing the sliding groove 5.13, after the handle 5.3 is pressed down to the lowest position, the handle 5.3 can be rotated to make the sliding block 5.14 enter the sliding groove 5.13, and the cooperation of the sliding groove 5.13 and the sliding block 5.14 is used to lock the handle 5.3 at the lowest displacement. Thus, during the process of pushing the cable anchor, the worker only needs to apply a thrust, which is more convenient for the worker to operate.

[0051] The technical scope of the present invention is not limited only to the content in the above specification. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
