[0002] In the current tunneling process, the roof and side anchor protection work is usually completed by manual operation. The device is simple, the labor intensity of miners is large, and the efficiency is not high. In the existing technology, the tunneling machine is provided with a roof bolter to reduce the labor intensity of workers and improve the efficiency. When the tunneling machine is working, the roof bolter is retracted on the side of the motor box of the tunneling machine, which increases the width of the cutting part and is prone to side scraping.

[0003] In addition, most of the existing onboard roof bolters are installed on a cantilever. When the roof bolter drills anchor holes, it needs to swing left and right through the cantilever to drill a row of anchor holes. When moving from hole to hole, not only does the cantilever need to swing left and right, but also it needs to stretch forward and backward, which makes the positioning action of the roof bolter complex and increases the difficulty of drilling.

[0011] The second driving part drives the second supporting pipe to slide out of the first accommodating cavity.

[0012] Further, the longitudinal section of the first supporting pipe and / or the second supporting pipe is matched with the longitudinal section of the first accommodating cavity.

[0013] Further, the first driving part and the second driving part are connected with the beam body through pin shafts, and the pin shafts are hingedly arranged on the beam body in the height direction.

[0015] Further, the beam body is provided with a transmission space with an upper opening, the transmission space is provided with a rack arranged along the length direction of the transmission space, the first telescopic mechanism comprises a guide frame sleeved outside the beam body, the guide frame is provided with a third driving part above, the power output end of the third driving part is provided with a gear, and the gear is in meshing transmission with the rack.

[0044] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0045] The embodiment relates to an anchor rod machine telescopic beam structure, which comprises a beam body 1, a supporting mechanism 4 telescopically connected to the beam body 1, and a first telescopic mechanism 2 and a second telescopic mechanism 3 drivingly connected to the beam body 1. The first telescopic mechanism 2 and the second telescopic mechanism 3 are respectively driven to move along the length direction of the beam body 1. The supporting mechanism 4 is driven to slide along the length direction of the beam body 1, and the supporting mechanism 4 extends away from the beam body 1 and abuts against a sidewall of a roadway.

[0046] The anchor rod machine telescopic beam structure of the embodiment can bidirectionally increase the drilling range of the anchor rod machine without increasing the width of the machine body, can adapt to roadways of various width specifications, and enables the anchor rod machine to extend the supporting mechanisms 4 away from each other in the working state, so that the supporting mechanisms 4 extend out from both sides and are supported on the sidewall of the roadway, the stability of the beam body 1 and the anchor rod machine is improved, a plurality of drill holes can be drilled in one supporting process, and the drilling efficiency is improved.

[0047] Based on the above overall introduction, an exemplary structure of the anchor rod machine telescopic beam structure in the embodiment is mounted on a heading machine to assemble into a heading and anchoring integrated machine. Of course, the anchor rod machine can also be fixed on a machine frame to be used as a special anchor rod machine. As shown in the figure, Figures 1-2 The beam body 1 of the embodiment is shaped into a long strip structure with a rectangular longitudinal section, and the first telescopic mechanism 2 and the second telescopic mechanism 3 are oppositely arranged on the beam body 1. Since the first telescopic mechanism 2 and the second telescopic mechanism 3 can be completely retracted into the length range of the beam body 1, the width of the beam body 1 can be set according to the width of the smallest roadway.

[0048] As a preferred implementation, the beam body 1 has a first accommodating cavity 101 arranged through the length direction of the beam body 1, and the supporting mechanism 4 comprises a first supporting pipe 401 and a second supporting pipe 402 oppositely sliding along the length direction of the first accommodating cavity 101. Figures 6-9 As shown in the figure, the beam body 1 is composed of a bottom plate 105, a top plate 106 and a side plate 107 arranged between the bottom plate 105 and the top plate 106, and the bottom plate 105, the top plate 106 and the two side plates 107 form a rectangular tube structure.

[0049] In addition, a partition plate 104 is arranged between the two side plates 107 and arranged through the length direction of the beam body 1, so as to divide the inner cavity of the beam body 1 into a second accommodating cavity 108 and the first accommodating cavity 101 arranged in front and back. The first accommodating cavity 101 is a full-length rectangular strip cavity, and the first supporting pipe 401 and the second supporting pipe 402 can slide relative to the first accommodating cavity 101.

[0050] Further, as shown in Figure 4 The beam body 1 is provided with a pivotally connected first driving part 201 and a second driving part 301, the first support pipe 401 is sleeved outside the first driving part 201, and the power output end of the first driving part 201 is pivotally connected with the first support pipe 401 to drive the first support pipe 401 to slide outside the first containing cavity 101. The second support pipe 402 is sleeved outside the second driving part 301, and the power output end of the second driving part 301 is pivotally connected with the second support pipe 402 to drive the second support pipe 402 to slide outside the first containing cavity 101.

[0051] The first driving part 201 and the second driving part 301 of the embodiment preferably adopt hydraulic oil cylinders, and as shown in Figure 4 The mounting seats of the two are adjacently arranged at the middle part of the beam body 1, and the position of the first driving part 201 and the second driving part 301 is fixed by arranging a pin shaft 202 in each mounting seat. The two ends of the pin shaft 202 are bolted and fixedly connected with the bottom plate 105 and the top plate 106. The power output ends of the two are arranged to the two sides of the beam body 1 respectively. And as shown in Figure 9 In order to keep the first driving part 201 and the second driving part 301 in the middle part of the cavity of the first containing cavity 101, a positioning sleeve 110 is sleeved on the pin shaft 202, and the two positioning sleeves 110 are respectively abutted between the top plate 106 and the mounting seat and between the bottom plate 105 and the mounting seat, so as to limit the height displacement of the mounting seat.

[0052] As shown in Figure 5 The first support pipe 401 and the second support pipe 402 both adopt rectangular pipes or rectangular profiles, and since the structures of the two are the same, the connection relationship is described by taking the first support pipe 401 as an example. A positioning pin penetrating the inner cavity of the first support pipe 401 is arranged along the width direction of the first support pipe 401, and the power output end of the first driving part 201 is sleeved on the positioning pin. The first driving part 201 drives the first support pipe 401 to move outward so that the side wall of the first support pipe 401 abuts on the sidewall of the roadway for support.

[0053] Correspondingly, the second driving part 301 drives the second support pipe 402 to move outward, and the first support pipe 401 and the second support pipe 402 can abut on the two opposite sidewalls of the roadway before the working of the anchor rod machine, so as to fix the beam body 1 and provide support for the hole punching of the anchor rod machine, thereby avoiding the low strength of the existing cantilever provided with the anchor rod machine and the vibration phenomenon of hole punching, improving the stability and reliability of the anchor rod machine during anchor punching, so as to effectively reduce the vibration of the rock wall and reduce rock falling;

[0054] By Figure 4 And Figure 5As shown, the length of the first support pipe 401 and the second support pipe 402 of the embodiment is slightly less than half of the length of the beam body 1, that is, when in the retracted state, the first support pipe 401 and the second support pipe 402 can be completely retracted, and do not occupy the equipment width space when the roadheader is running, and are suitable for narrow or medium-sized roadway construction.

[0055] In addition, the longitudinal section of the first support pipe 401 and the second support pipe 402 is matched with the longitudinal section of the first accommodating cavity 101. By matching the longitudinal section of the first support pipe 401 and / or the second support pipe 402 with the longitudinal section of the first accommodating cavity 101, not only can the guiding effect of the sliding of the first support pipe 401 and the second support pipe 402 be achieved, but also the part of the first support pipe 401 and the second support pipe 402 that is extended can be shaken with the beam body 1 due to the weight of the anchor rod machine. Of course, the longitudinal section of the first support pipe 401 or the second support pipe 402 can also be provided with a gap with the longitudinal section of the first accommodating cavity 101, and a plain bearing or a copper sheet is added at the gap position to improve the movement flexibility of the first support pipe 401 and the second support pipe 402.

[0056] Preferably, the first support pipe 401 and the second support pipe 402 are provided with a baffle plate 403 on both sides, and the baffle plate 403 is provided with a conical frustum 404 protruding outward, and the conical frustum 404 is placed on the sidewall of the roadway when the anchor rod machine is in the working state. As shown in Figure 4 and Figure 6 As shown, the conical frustum 404 is a conical frustum 404 shape protruding outward of the beam body 1, which is used to enable the first support pipe 401 and the second support pipe 402 to be inserted into the sidewall of the roadway, and further ensures the supporting effect.

[0057] In addition, as shown in Figure 7 and Figure 9 As shown, the second accommodating space adjacent to the first accommodating space is provided, and the inspection hole 109 penetrating through the partition plate 104 and the side plate 107 thereof is provided, and the inspection hole 109 is communicated into the first accommodating cavity 101, so that the oil injection pipe and the oil outlet pipe of the first driving part 201 and the second driving part 301 can be penetrated out of the second accommodating cavity 108 and then connected to the external pump station. In this way, the rationality and neatness of the arrangement of the telescopic beam structure of the anchor rod machine are ensured, and maintenance is facilitated.

[0058] As a preferred embodiment, the beam body 1 is provided with an upper opening transmission space 102 above, the transmission space 102 is provided with a rack 103 arranged along the length direction thereof, the first telescopic mechanism 2 includes a guide frame 203 sleeved outside the beam body 1, the guide frame 203 is provided with a third driving part 204 above, the power output end of the third driving part 204 is provided with a gear 205, and the gear 205 is in meshing transmission with the rack 103.

[0059] AsFigures 1-2 As shown, the top of the side plates 107 on both sides is higher than the top plate 106, so that the top plate 106 and the side plates 107 on both sides form an upper open transmission space 102, and the rack 103 is fixedly connected in the transmission space 102. Figure 8 As shown, the top plate 106 is provided with an elongated blind groove for positioning the rack 103, and the rack 103 is fixed in the blind groove by bolts.

[0060] As shown in Figure 1 and Figure 2 The guide frame 203 is composed of an upper plate 4011 provided on the upper part of the top plate 106 and middle plates 4012 provided on both sides of the upper plate 4011 and extending downward. The upper plate 4011 and the two middle plates 4012 are arranged outside the beam body 1, and the lower plate 4013 is arranged below the two middle plates 4012, so as to form a rectangular frame structure for the guide frame 203. The third driving part 204 is arranged above the upper plate 4011, and the power output shaft thereof extends through the upper plate 4011 to the transmission space 102. The third driving part 204 of the present embodiment is a speed reducer motor, and a gear 205 is sleeved on the power output shaft of the motor. The gear 205 is engaged with the rack 103.

[0061] When the third driving part 204 is started, the first telescopic mechanism 2 moves along the beam body 1 in the width of the roadway. In the present embodiment, the first telescopic mechanism 2 is arranged opposite to the second telescopic mechanism 3. The fifth driving part 302 is arranged on the second telescopic mechanism 3. When the third driving part 204 is started, the fifth driving part 302 drives the second telescopic mechanism 3 to move along the beam body 1 in the width of the roadway. The two anchor rod machines can continuously drill holes at any position in the width of the roadway, avoiding the difficulty of three-dimensional adjustment of the cantilever in the prior art, and realizing linear two-dimensional adjustment of the drilling position. This not only improves the drilling efficiency, but also further ensures the accuracy and stability of the movement position of the anchor rod machine due to the transmission of the gear 205 and the rack 103.

[0062] It should be noted that the first telescopic mechanism 2 and the second telescopic mechanism 3 can independently move left and right due to independent driving sources, thereby improving the convenience and flexibility of the use of the equipment.

[0063] Preferably, as shown in Figures 1-2 The first telescopic mechanism 2 of the present embodiment is further provided with a fourth driving part 206 for driving the rotation of the anchor rod machine. The rotation direction of the anchor rod machine is parallel to the side surface of the beam body 1. The fourth driving part 206 is a hydraulic rotary motor. The full-circumferential rotation of the anchor rod machine can be realized by the driving of the fourth driving part 206, so as to adapt to the adjustment of the drilling of the anchor rod machine at different positions in the roadway.

[0064] In addition, as shown in Figures 1-2As shown, in the embodiment, the guide frame 203 is provided with an operation platform 207 above, and a pedal 208 provided reversibly below the guide frame 203, the pedal 208 is provided correspondingly above and below the operation platform 207. In this way, the operator can replace the anchor rod and operate the anchor rod machine conveniently, and the practicability of the equipment is improved.

[0065] In addition, as Figures 1-2 As shown, the beam body 1 is provided with a rotary support 209 below, and the rotary support 209 is pivotally connected with external equipment. As Figure 6 As shown, by providing the rotary support 209 on the bottom plate 105, the anchor rod machine telescopic beam structure and the anchor rod machine can adjust the angle with the tunneling machine, further increase the flexibility of the tunneling machine, and facilitate the automatic drilling.

[0066] The anchor rod machine telescopic beam structure of the embodiment can increase the drilling range of the anchor rod machine bidirectionally without increasing the width of the machine body, can adapt to various specifications and widths of the roadway, and also makes the anchor rod machine in the working state extend the supporting mechanism 4 from both sides to support on the roadway side, strengthens the stability of the beam body 1 and the anchor rod machine, realizes drilling multiple holes at one time, and improves the drilling efficiency.

[0067] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
