[0037] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] This embodiment provides a mobile power box, which is applied to a rock drilling rig, such as Figure 2-Figure 6As shown, the mobile power box includes a storage box 100 with a storage cavity 110 formed inside and a drawer 200 for containing batteries. The first side end of the storage box 100 is provided with an opening, and the drawer 200 is detachably plugged into the storage cavity 110 through the opening. The side panel of the drawer 200 corresponding to the first side end is a first side panel 211, and the two side panels of the drawer 200 in the width direction are a second side panel 212 and a third side panel 213, respectively, and the first side panel 211 is sealed in the opening.

[0039] This embodiment also provides a rock drilling rig, such as Figure 1 As shown, it includes a mounting frame 300, a traveling device, an operating device 600 and the above-mentioned mobile power box. The traveling device is installed at the bottom of the mounting frame 300, and the operating device 600 and the mobile power box are both installed on the mounting frame 300. The drawer 200 of the mobile power box contains batteries, and the first side panel 211 of the drawer 200 faces the outside of the drilling rig.

[0040] The present embodiment provides a mobile power box and a rock drilling trolley, wherein the mobile power box comprises a drawer 200 for containing batteries and a storage box 100 for accommodating the drawer 200, and when the drawer 200 is inserted into the storage box 100, the first side panel 211 of the drawer 200 can block the opening of the storage box 100; wherein the rock drilling trolley comprises a mounting frame 300 as a mounting base, an operating device 600 for operations such as rock drilling, a traveling device for driving the mounting frame 300 and the operating device 600 to move, and the above-mentioned mobile power box for carrying batteries, and batteries are contained in the drawer 200 of the mobile power box.

[0041] When in use, the battery is contained in the drawer 200, and the drawer 200 is inserted into the storage box 100 through the opening of the storage box 100, and the first side plate 211 of the drawer 200 is blocked at the opening of the storage box 100 to reduce the occurrence of the battery in the drawer 200 falling out; the battery is connected to the traveling device and the working device 600 that require electrical energy to supply power to them. During the operation of the rock drilling trolley, the traveling device drives the mounting frame 300 to move, and the working device 600, the mobile power box and the battery therein can move synchronously with the mounting frame 300 to ensure continuous power supply of the battery, so that the rock drilling trolley can move as an independent individual when working, without being restricted by external power supplies and cables, thereby increasing the operating range of the rock drilling trolley and improving its convenience and flexibility in movement.

[0042] In addition, since the first side panel 211 of the drawer 200 faces the outside of the drilling trolley, when the battery needs to be charged, repaired or replaced, the drawer 200 can be pulled outward through the opening and then the battery can be operated accordingly. The above arrangement can greatly improve the convenience of pulling out, installing, etc. the drawer 200, and there is no need to set up a working space on the drilling trolley for the above operations, which can effectively reduce the size of the drilling trolley.

[0043] Optionally, after the drawer 200 is inserted into the storage box 100, a connector can be used to detachably fix the first side panel 211 of the drawer 200 to the end face of the first side end of the storage box 100, so as to reduce the possibility of the drawer 200 sliding out of the storage box 100 or even falling due to vibration during the operation of the drilling rig, thereby ensuring the stability of battery power supply.

[0044] Specifically, the working device 600 may include a drill arm for drilling operations and a power assembly for driving the drill arm to adjust the direction.

[0045] Optionally, in this embodiment, if Figure 7 As shown, the mobile power box may also include a rolling assembly, which includes two rollers 250; one of the rollers 250 is pivotally connected to the outer wall of the second side panel 212, and the other roller 250 is pivotally connected to the outer wall of the third side panel 213, and the two rollers 250 correspond to each other along the width direction of the drawer 200; the spacing between the outer end surfaces of the two rollers 250 along the width direction of the drawer 200 is consistent with the width of the accommodating cavity 110. The setting of the rolling component, on the one hand, during the process of pulling out the drawer 200, the roller 250 of the rolling component can support the drawer 200, and the roller 250 and the bottom plate of the storage box 100 are in rolling connection, and the friction between the two is much smaller than the sliding friction between the drawer 200 and the bottom plate of the storage box 100 when it is directly pulled out, thereby reducing the resistance encountered by the drawer 200 during the pulling out process and improving the smoothness of pulling out the drawer 200; on the other hand, during the pulling out process of the drawer 200, the two rollers 250 of the rolling component respectively abut against the two side walls in the width direction of the storage chamber 110, that is, the above-mentioned two side side plates can guide and limit the rolling path of the two rollers 250, and correspondingly guide and limit the pulling out path of the drawer 200, thereby improving the position accuracy of the pulling out of the drawer 200 and reducing the occurrence of the drawer 200 being stuck in the storage box 100 due to the displacement of the drawer 200.

[0046] Optionally, in this embodiment, if Fig. 9As shown, the drawer 200 includes an outer containing part 220, a middle containing part 230 and an inner containing part 240 in sequence from the first side panel 211 to the other end along its length direction. There are two groups of rolling assemblies, both of which are located in the inner containing part 240, and the two groups of rolling assemblies are arranged at intervals along the length direction of the inner containing part 240; the inner walls of the two side panels in the width direction of the storage box 100 are provided with guide rails 120, and the two guide rails 120 extend inward from the first side end along the length direction of the storage box 100, and a guide groove 130 is formed between the guide rail 120 and the bottom plate inside the storage box 100, and the roller 250 matches the guide groove 130. Specifically, along the length direction of the drawer 200, the side panel opposite to the first side panel 211 can be defined as the fourth side panel 214; when the drawer 200 needs to be pulled out, the drawer 200 is pulled out to a certain length, and the rollers 250 of the two sets of rolling assemblies all roll into the guide grooves 130. When the center of gravity of the drawer 200 is located outside the storage box 100, the two sets of rollers 250 arranged at intervals jointly support the drawer 200 under the limiting action of the two guide rails 120 to ensure that the drawer 200 is in a horizontal state, reducing the drawer 200 from being pulled out to a certain length. When the center of gravity of the drawer 200 is located outside the storage box 100, one end of the fourth side panel 214 of the drawer 200 is tilted upward under the action of gravity, causing the drawer 200 to slide.

[0047] In this embodiment, Fig. 9 As shown, a partition 260 can be provided in the drawer 200 along its width direction, and there are two partitions 260, one of which is located between the outer container 220 and the middle container 230, and the other is located between the middle container 230 and the inner container 240. The partition 260 can be provided, on the one hand, to support between the second side plate 212 and the third side plate 213, thereby improving the firmness of the shape of the entire drawer 200; on the other hand, the partition 260 divides the inner space of the drawer 200 into three container chambers, and the batteries can be respectively loaded into the three container chambers, so as to effectively improve the neatness and stability of the multiple batteries loaded in the drawer 200. Specifically, there can be twelve batteries, and three batteries can be loaded into each container chamber; in addition, a charging head can be installed in the storage box 100, and the charging head is connected to each battery, so that the user can charge the battery directly with the external synchronous charging head without pulling out the drawer 200, thereby further improving the convenience of using the mobile power box.

[0048] In this embodiment, Fig. 9 As shown, guide strips 270 may be fixedly provided on the outer walls of the second side plate 212 and the third side plate 213 along their length directions; Figure 8 As shown, the inner walls of the two side plates of the container box 100 in the width direction are both pivotally connected with guide wheels 140, and the two guide wheels 140 correspond to the two guide strips 270 one by one, as shown in FIG. Figure 6As shown, the guide bar 270 is overlapped on the corresponding guide wheel 140. The guide wheel 140 is rollingly supported at the bottom of the guide bar 270. When the drawer 200 is pulled out, firstly, the guide wheel 140 can support the guide bar 270 in the height direction, and then limit the position of the drawer 200 in the height direction, so as to further improve the position accuracy and smoothness of the drawer 200 in the accommodating cavity 110 during the pull-out process; secondly, during the pull-out process of the drawer 200, there is rolling friction between the guide wheel 140 and the guide bar 270, and the friction force is small, so as to reduce the resistance encountered by the drawer 200 during the pull-out process, and further improve the smoothness of the pull-out process.

[0049] Specifically, the guide wheel 140 and the roller 250 can both use bearings, wherein the outer ring of the bearing serves as a rolling wheel body.

[0050] In this embodiment, Figure 1 As shown, the walking device may include an active walking body 400 and a passive walking body 500, the active walking body 400 is installed at the head end of the mounting frame 300, and the passive walking body 500 is installed at the tail end of the mounting frame 300; the passive walking body 500 includes a carriage and a passive wheel 510 pivotally connected to the carriage, wherein the storage box 100 of the mobile power box is used as the carriage. This is a specific form of a traveling device, in which the active traveling body 400 and the driven traveling body 500 respectively support the front end and the rear end of the mounting frame 300, and the active traveling body 400 serves as a power device to drive the entire drilling trolley to move; in addition, the storage box 100 of the mobile power box is used as a carriage of the driven traveling body 500, the driven wheel 510 is pivotally connected to the bottom of the storage box 100, and the drawer 200 and batteries are contained in the storage box 100, so that the storage box 100 has multiple uses and can make full use of the space occupied by the carriage, thereby effectively improving the structural compactness of the drilling trolley, correspondingly reducing its volume, and further improving its flexibility in moving in the tunnel.

[0051] In this embodiment, Figure 2 and Figure 7 As shown, there may be two driven wheels 510, and the two driven wheels 510 are pivotally connected to the outer walls of the two side plates in the width direction of the storage box 100 in a one-to-one correspondence; the outer walls of the two side plates in the width direction of the storage box 100 are also pivotally connected to a driven auxiliary wheel 520. The driven auxiliary wheel 520 can assist the driven wheel 510 in supporting different positions of the driven walking vehicle body 500 to improve its support stability; preferably, the wheel diameter of the driven auxiliary wheel 520 can be smaller than the wheel diameter of the driven wheel 510. During the movement of the driven walking vehicle body 500, the rotation speeds of the driven auxiliary wheel 520 and the driven wheel 510 are different, which can effectively reduce the vibration force of the driven walking vehicle body 500, and correspondingly improve its movement stability.

[0052] Optionally, in this embodiment, if Figure 7 As shown, the first end face of the driven wheel 510 along its axial direction is provided with an outward-turned first flange 511. This is a specific arrangement form when the driven wheel 510 is used in conjunction with the track, wherein the first end face here refers to the end face of the driven wheel 510 facing the receiving box 100. When the driven wheel 510 is pressed on the track in the tunnel and there are two driven wheels 510, the two first flanges 511 of the two driven wheels 510 are respectively in contact with the inner side walls of the two tracks, thereby limiting the displacement of the receiving box 100 and the driven wheel 510 in the width direction of the track to ensure the cooperative connection between the driven wheel 510 and the track.

[0053] In addition, a second outward-turned flange can also be provided on the second end face of the driven wheel 510 along its axial direction; the two second flanges of the two driven wheels 510 respectively abut against the outer walls of the two tracks, further limiting the driven wheels 510 relative to the track width direction, further improving the matching position accuracy between the driven wheels 510 and the tracks, and reducing the occurrence of displacement or even derailment of the driven wheels 510.

[0054] Similarly, a third flange 521 may be provided on the first end face of the driven auxiliary wheel 520 along its axial direction, and a fourth flange may be provided on the second end face of the driven auxiliary wheel 520 along its axial direction. The third flange 521 and the fourth flange limit the driven auxiliary wheel 520 in the track width direction to ensure the matching position accuracy between the driven auxiliary wheel 520 and the track.

[0055] In this embodiment, Figure 4 As shown, a rotating body 530 may be fixedly connected to the top of the traveling device, a rotating base 540 may be fixedly connected to the bottom of the mounting frame 300, and the rotating body 530 is pivotally connected to the rotating base 540. The traveling device is pivotally connected to the mounting frame 300 through the rotational cooperation of the rotating body 530 and the rotating base 540, and the traveling device can perform 360° circumferential rotation relative to the mounting frame 300 in the horizontal direction. When turning is required, under the guidance of the track in the tunnel, the traveling device can adjust the direction along the track, so that the spacing and relative angle between the driving wheel on the active traveling vehicle body 400 and the driven wheel 510 on the driven traveling vehicle body 500 are adapted to the track, thereby reducing the restriction of the entire drilling vehicle body length when the drilling vehicle turns, and the entire vehicle body can also be turned in a small space or when the turning radius is small, which correspondingly improves the flexibility of the drilling vehicle displacement in the tunnel and improves its convenience of use.

[0056] Specifically, one of the active traveling body 400 and the passive traveling body 500 can be pivotally connected to the mounting frame 300, or both can be pivotally connected to the mounting frame 300; and when the passive traveling body 500 is pivotally connected to the mounting frame 300, as Figure 5As shown, a threading hole 560 for passing the power line can be provided at the axis of the rotating body 530 and the rotating base 540; a through hole connected to the threading hole 560 is provided on the top of the storage box 100. The connection line between the battery in the drawer 200 and the walking device and the working device 600 passes through the through hole and the threading hole 560 to realize the battery to supply power to the outside.

[0057] In this embodiment, Figure 4 As shown, the rotary base 540 can be provided with an annular groove 550 along its circumference, and the cross section along the depth of the annular groove 550 is an upward convex spherical surface, the rotary body 530 is rotatably clamped in the annular groove 550, and the rotary body 530 matches the annular groove 550 to form a spherical shape. The annular groove 550 is a spherical groove, the rotary body 530 cooperates with the spherical groove, and the rotary body 530 is sleeved between the sleeve hole of the rotary base 540 and the rotary base 540 to form an adjustment space. On the basis of realizing the circumferential rotation of the rotary body 530, that is, on the basis of realizing the pivotal connection of the driven traveling vehicle body 500 to the mounting frame 300, within a certain range, the rotary body 530 can also rotate in various directions along the spherical surface in the spherical groove, thereby increasing the adjustment range of the driven traveling vehicle body 500 in various directions, further improving its displacement flexibility, so that the rock drilling trolley can adapt to various terrains in the tunnel and can move smoothly.

[0058] Optionally, in this embodiment, if Figure 2 and Figure 4 As shown, a driven protective cover 570 may be fixedly connected to the bottom of the mounting frame 300, the slewing base 540 may be fixedly connected to the driven protective cover 570, the receiving box 100 and the driven wheel 510 may be received in the driven protective cover 570, and the slewing body 530 may be fixedly connected to the top of the receiving box 100. The driven protective cover 570 may protect the mobile power supply device, the battery, the driven wheel 510, etc., to reduce damage to them caused by external factors.
