Description

Technical Field

[0001] The utility model relates to the technical field of on-site explosive mixing vehicles, in particular to a pipe delivery device. Background Art

[0002] Currently in mining operations, the on-site explosives mixing truck can use the tube feeder fixed on the hanging basket to send the explosives into the blasthole through the tube feeder. The tube feeder plays a vital role and is a key component to ensure the automation and intelligent realization of charging.

[0003] There are some problems in the use of existing pipe feeders. Since the inclination angles of various blast holes are different, in order to adapt to blast holes with different inclination angles, it is necessary to raise or lower the boom of the on-site explosive mixing truck to adjust the inclination angle of the drug delivery pipe to roughly match the inclination angle of the blast hole, which greatly reduces work efficiency. Utility Model Content

[0004] In view of the above-mentioned defects, the technical problem to be solved by the present invention is to provide an active device for a pipe feeder, which can enable the pipe feeder to adapt to blast holes with different inclination angles and improve work efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A tube feeder active device, comprising:

[0007] Fixed seat;

[0008] a movable member rotatably mounted on the fixed seat and configured to be rotatable along a vertical plane;

[0009] The movable seat is rotatably mounted on the movable member and is configured to be rotatable along a plane perpendicular to the vertical plane. The movable seat is used to connect the pipe feeder.

[0010] By adopting the above solution, the fixed base is installed on the hanging basket of the on-site explosive mixing vehicle, and the pipe feeder is installed on the movable base. During the pipe feeding operation, since the movable base can rotate relative to the fixed base in both the vertical plane and the direction perpendicular to the vertical plane, the operator can freely rotate the inclination angle of the pipe feeder, so that the pipe feeder can adapt to blastholes with different inclination angles, thereby allowing the drug delivery tube delivered by the pipe feeder to adapt to blastholes with different inclination angles. There is no need to adjust the angle of the drug delivery tube by adjusting the boom of the on-site explosive mixing vehicle, which effectively improves work efficiency.

[0011] The utility model is further configured such that the movable part includes a first sleeve and a second sleeve connected to each other, a first rotating shaft is provided in the first sleeve, the first rotating shaft is rotatably connected to the fixed seat, a second rotating shaft is rotatably connected in the second sleeve, and one end of the second rotating shaft is fixedly connected to the movable seat.

[0012] The present invention further comprises a first through hole formed in the first sleeve, a locking bolt passing through the first through hole, a first mounting hole formed in the first rotating shaft, and a section of the locking bolt threadedly connected to the first mounting hole. The locking bolt threadedly connected to the first mounting hole prevents relative rotation between the first rotating shaft and the first sleeve, while also facilitating installation and removal of the first rotating shaft and the first sleeve.

[0013] The present invention further comprises a stop ring disposed on the second rotating shaft, the stop ring having a plurality of stop holes formed along a circumferential direction, a first stop pin disposed within at least one of the stop holes, and a stop portion disposed on the outer side of the second sleeve, the stop portion being located along the path of the first stop pin's circumferential motion around the second rotating shaft. The stop portion and the first stop pin cooperate to limit the maximum clockwise or counterclockwise rotation angle of the second rotating shaft, thereby limiting the maximum rotation angle of the movable seat and preventing the movable seat from having an excessive range of motion that could affect the operator's operation.

[0014] The present invention is further configured such that the first limit pin is threadedly connected to the limit hole. Since the first limit pin is threadedly connected to the limit hole, the first limit pin can be easily removed, thereby facilitating installation of the first limit pin into the limit hole at a different position, thereby enabling adjustment of the maximum rotation angle of the second rotating shaft.

[0015] The present invention is further configured such that the fixed base includes an end plate and a side plate, one side of the end plate is fixedly connected to the two side plates, and the movable member is rotatably mounted between the two side plates. The movable member is arranged between the two connecting plates, making the overall structure more compact and more stable.

[0016] The present invention is further configured such that the fixed seat further comprises a first positioning plate, the first positioning plate being fixedly connected to the top of the side plate, the first positioning plate being provided with a second through-hole, the movable seat being provided with a third through-hole, the third through-hole being inserted with a second limiting pin, and the second limiting pin being simultaneously inserted into the second through-hole. The second limiting pin can lock the movable seat and the first positioning plate, thereby locking the movable seat and the fixed seat, preventing the movable seat from rotating freely when not needed.

[0017] The present invention is further configured such that the fixed base further includes a second positioning plate, the second positioning plate being fixedly connected between the two side plates, the second positioning plate being provided with a second mounting hole, an adjustment bolt being threadedly connected to the second mounting hole, the two side plates being hingedly connected to a support member via a third rotating shaft, the top end of the adjustment bolt abutting against the lower side of the support member, and the free end of the support member abutting against the lower side of the movable base. The height of the support member can be adjusted by the adjustment bolt, and the maximum rotation angle of the movable base along the vertical plane is limited by the free end of the support member.

[0018] The utility model further comprises a shaft hole formed in the side panels for the first rotating shaft to pass through, a bearing seat fixedly connected to the side panels, a bearing disposed inside the bearing seat, and two ends of the first rotating shaft respectively passing through the shaft holes in the two side panels and connected to corresponding bearings. The first rotating shaft is connected to the corresponding side panels via the bearings, thereby ensuring the stability of the first rotating shaft's rotation.

[0019] The utility model is further configured such that a plurality of fourth through holes are formed on the end plate, through which bolts can be conveniently installed, thereby facilitating the fixing base to be fixed to the hanging basket of the on-site explosive mixing vehicle.

[0020] In summary, the tube feeder active device provided by the present invention has at least the following beneficial effects:

[0021] 1. The movable seat for installing the tube feeder can rotate along the vertical plane and the plane perpendicular to the vertical plane. The tube feeder can deflect at a large angle to adapt to blastholes with different inclinations.

[0022] 2. The maximum rotation angle of the movable seat can be adjusted to facilitate operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make those skilled in the art better understand the technical solution of the utility model, Figure 1-9 The present invention is further described in detail with reference to the following specific embodiments.

[0035] See also Figure 1-9 This embodiment provides a flexible device for a tube feeder, comprising a fixed base 1, a movable member 2, and a movable base 3. The movable member 2 is rotatably mounted on the fixed base 1 and configured to rotate along a vertical plane. The movable base 3 is rotatably mounted on the movable member 2 and configured to rotate along a plane perpendicular to the vertical plane. The movable base 3 is used to connect to a tube feeder 19. The movable base 3 is specifically plate-shaped, with a plurality of fifth through holes 20 defined on its upper side. The fifth through holes 20 are symmetrically arranged in two rows. The fifth through holes 20 facilitate connection of the base of the tube feeder 19 to the movable base 3 via bolts and nuts.

[0036] By adopting the above solution, during use, the fixed base 1 is installed on the hanging basket of the on-site explosive mixing vehicle, and the pipe feeder 19 is installed on the movable base 3. During the pipe feeding operation, since the movable base 3 can rotate relative to the fixed base 1 in both the vertical plane and the direction perpendicular to the vertical plane, the operator can freely rotate the inclination angle of the pipe feeder 19, so that the pipe feeder 19 can adapt to blastholes with different inclination angles, thereby allowing the drug delivery tube delivered by the pipe feeder 19 to adapt to blastholes with different inclination angles. There is no need to adjust the angle of the drug delivery tube by adjusting the boom of the on-site explosive mixing vehicle, which effectively improves work efficiency.

[0037] See also Figure 7 and Figure 8 The movable member 2 includes a first sleeve 201 and a second sleeve 202 connected to each other. Specifically, the first sleeve 201 and the second sleeve 202 are connected by a connecting arm 205. The left and right ends of the connecting arm 205 are fixedly connected to the first sleeve 201 and the second sleeve 202 respectively. Figure 4 A first rotating shaft 4 is provided in the first sleeve 201 and is rotatably connected to the fixed seat 1. A second rotating shaft 5 is rotatably connected in the second sleeve 202, and the upper end of the second rotating shaft 5 is fixedly connected to the movable seat 3. To ensure smooth rotation of the second rotating shaft 5 in the second sleeve 202, a shaft sleeve 21 is further provided in the second sleeve 202, and the second rotating shaft 5 is rotatably connected in the shaft sleeve 21.

[0038] See also Figure 4 and 7 The first sleeve 201 defines a first through-hole 204, into which a locking bolt 6 is inserted. The first rotating shaft 4 defines a first mounting hole 7, into which a section of the locking bolt 6 is threaded. The second rotating shaft 5 is provided with a retaining ring 8, which is fixedly connected to the second rotating shaft 5. The retaining ring 8 defines a plurality of retaining holes 9 along a circumferential direction, and at least one retaining hole 9 is provided with a first retaining pin 10, which is threadedly connected to the retaining hole 9. A retaining portion 203 is provided on the outer side of the second sleeve 202. The retaining portion 203 is located along the path of the first retaining pin 10's circumferential motion around the second rotating shaft 5. The first retaining pin 10 can limit the maximum clockwise or counterclockwise rotation angle of the second rotating shaft 5. For example, after clockwise rotation reaches a certain angle, the first retaining pin 10 is blocked by the retaining portion 203 protruding from the outer side of the second sleeve 202, thereby limiting the maximum rotation angle of the second rotating shaft 5. In this embodiment, two first limiting pins 10 are preferably provided, which are threadedly connected to the limiting holes 9 at different positions, thereby limiting the maximum angles of the second rotating shaft 5 in both counterclockwise and clockwise rotation.

[0039] See also Figure 4In order to improve the smoothness of the rotation of the second rotating shaft 5, as a preference, a thrust bearing 18 is provided on the second rotating shaft 5, and the thrust bearing 18 is arranged between the limiting ring 8 and the shaft sleeve 21.

[0040] See also Figure 1 The fixed seat 1 includes an end plate 101 and a side plate 102. The left side of the end plate 101 is fixedly connected to two side plates 102. The two side plates 102 are spaced apart along the front-to-back direction, and the movable part 2 is rotatably installed between the two side plates 102.

[0041] See also Figure 2 、 4 , 5, 6, the fixed seat 1 also includes a first positioning plate 103, the first positioning plate 103 is fixedly connected to the top of the side plate 102, and the two ends of the first positioning plate 103 are fixedly connected to the two side plates 102 respectively. A second through hole 104 is provided on the first positioning plate 103, and a third through hole 11 is provided on the movable seat 3. A second limit pin 12 is inserted into the third through hole 11, and the second limit pin 12 is also passed through the second through hole 104. The second limit pin 12 can limit the relative rotation between the movable seat 3 and the first positioning plate 103, and at the same time, it can also limit the rotation of the movable seat 3 in the vertical plane. When the movable device is not in use, the movable seat 3 can be locked by the second limit pin 12 to prevent the movable seat 3 from moving freely.

[0042] See also Figure 4 The fixed base 1 also includes a second positioning plate 105, which is fixedly connected between the two side plates 102. A second mounting hole is defined in the second positioning plate 105, into which an adjustment bolt 13 is threadedly connected. A support member 15 is hingedly connected between the two side plates 102 via a third rotating shaft 14. The top end of the adjustment bolt 13 abuts against the underside of the support member 15, and the free end of the support member 15 abuts against the underside of the movable base 3. By rotating the adjustment bolt 13, the height to which the support member 15 is lifted can be adjusted, thereby limiting the maximum elevation angle of the movable base 3.

[0043] See 2 and Figure 5 An axial hole is opened on the side plate 102 for the first rotating shaft 4 to pass through. A bearing seat 16 is fixedly connected to the outer side of the side plate 102. A bearing 17 is provided on the inner side of the bearing seat 16.
