Description

Technical Field

[0001] The utility model relates to the technical field of charging trucks, in particular to a charging hole alignment device and a charging truck. Background Art

[0002] In the charging and blasting construction of metal and non-metal mines, roadway driving, and tunnel engineering, construction methods mainly include drilling, charging, blasting, and mucking. At present, manual charging and blasting is still mainly used. Due to the continuous innovation of blasting technology, most blasts in mines or tunnels use automatic charging by charging trucks. The basic principle is to move the hole alignment device to the vicinity of the blast hole through the telescopic arm of the charging truck, and then extend the feeding hose into the blast hole through the charging hole alignment device to transport the detonating cartridges and explosives. After the feeding is completed, the feeding hose is withdrawn.

[0003] However, when the existing charging hole alignment device bends the drug delivery hose, the wear on the drug delivery hose is relatively large, resulting in a relatively high frequency of replacing the drug delivery hose. Therefore, it is necessary to design a charging hole alignment device that can reduce the wear on the drug delivery hose. Summary of the Utility Model

[0004] In view of the above problems in the prior art, the present application proposes a charging hole alignment device and a charging truck that can reduce the wear on the drug delivery hose.

[0005] One aspect of the utility model provides a charging hole alignment device. The charging hole alignment device includes a slewing bearing, a link mechanism, and a charging hose. The link mechanism is installed on the slewing bearing. The charging hose passes through the slewing bearing and the link mechanism. A plurality of conduit mechanisms are sequentially installed on the link mechanism. The conduit mechanism includes a support frame. The support frame is hinged to the link mechanism. Two rows of concave wheels are installed on the support frame at intervals up and down. The charging hose is limited between the two rows of concave wheels.

[0006] As a further improvement of the above technical solution:

[0007] In the above charging hole alignment device, further, a rubber pad is coated on the outer side wall of the concave wheel, and the concave wheel contacts the charging hose through the rubber pad.

[0008] In the above charging hole alignment device, further, the link mechanism includes a mounting seat and two sets of link components. The mounting seat is installed on the slewing bearing. The two sets of link components are both hinged to the mounting seat and are respectively arranged on both sides of the conduit mechanism relatively. The link component includes a plurality of support links extending up and down and hinged in sequence. A first telescopic driving member is provided between the ends of two adjacent support links on the upper side. A second telescopic driving member is provided between the ends of two adjacent support links on the lower side. Both ends of the support frame are hinged to the support links.

[0009] For the above-mentioned charge hole-aligning device, further, a connecting seat is hinged to the end of the connecting rod assembly, a hole-aligning pipe is installed on the connecting seat, and the end of the charge hose extends into the hole-aligning pipe.

[0010] For the above-mentioned charge hole-aligning device, further, a connecting link is hinged between two adjacent support connecting rods extending from bottom to top.

[0011] For the above-mentioned charge hole-aligning device, further, both the first telescopic driving member and the second telescopic driving member are hydraulic cylinders.

[0012] On the other hand, the present utility model provides a charge truck, which has the above-mentioned charge hole-aligning device.

[0013] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the present utility model can be achieved.

[0014] Compared with the prior art, the charge hole-aligning device and the charge truck provided by the present utility model at least have the following beneficial effects: When charge blasting operation is required, the slewing bearing of the hole-aligning device is installed on the robotic arm of the charge truck. First, the robotic arm moves the hole-aligning device to the vicinity of the blast hole, and then according to the position of the charge hose relative to the blast hole, the slewing bearing rotates and the connecting rod mechanism expands and contracts in cooperation to align the charge hose with the blast hole and extend it into the blast hole to convey the detonating cartridge and explosive. After the medicine delivery is completed, the charge hose is withdrawn. Since the charge hose is limited between two rows of cam wheels, when the medicine delivery hose passes through the curved connecting rod mechanism, the medicine delivery hose rolls into contact with the cam wheels, thereby reducing the wear of the medicine delivery hose and reducing the frequency of replacing the medicine delivery hose.

[0029] The embodiment of the present utility model provides a charge hole-aligning device, which can reduce the wear of the medicine delivery hose.

[0030] Please refer to Figure 1 and Figure 2 , the charge hole-aligning device 100 provided by the embodiment of the present utility model. The charge hole-aligning device 100 includes a slewing bearing 110, a linkage mechanism 120 and a charge hose. The linkage mechanism 120 is installed on the slewing bearing 110. The charge hose passes through the slewing bearing 110 and the linkage mechanism 120. A plurality of conduit mechanisms 130 are sequentially installed on the linkage mechanism 120. The conduit mechanism 130 includes a support frame 131. The support frame 131 is hinged to the linkage mechanism 120. Two rows of concave wheels 132 are installed on the support frame 131 at intervals up and down. The charge hose is limited between the two rows of concave wheels 132.

[0031] When charge blasting operation is required, the slewing bearing 110 of the hole-aligning device is installed on the robotic arm of the charge truck. First, the robotic arm moves the hole-aligning device to the vicinity of the blast hole. Then, according to the position of the charge hose relative to the blast hole, the slewing bearing 110 rotates and the linkage mechanism 120 expands and contracts in cooperation to align the charge hose with the blast hole and extend it into the blast hole to deliver the detonating cartridge and explosive. After the medicine delivery is completed, the charge hose is withdrawn. Since the charge hose is limited between the two rows of concave wheels 132, when the medicine delivery hose passes through the curved linkage mechanism 120, the medicine delivery hose rolls in contact with the concave wheels 132, thereby reducing the wear of the medicine delivery hose and reducing the frequency of replacing the medicine delivery hose.

[0032] The charge loading and hole aligning device 100 provided by the embodiment of the present utility model. Further, a rubber pad is coated on the outer side wall of the cam 132, and the cam 132 contacts the charge loading hose through the rubber pad. The rubber pad is made of a flexible material, which can further reduce the wear of the medicine delivery hose, avoid damaging the medicine delivery hose at the same time, and the rubber pad has the characteristic of wear resistance.

[0033] The charge loading and hole aligning device 100 provided by the embodiment of the present utility model. Specifically, please refer to Figure 1 and Figure 2 , the link mechanism 120 includes a mounting seat 121 and two sets of link components. The mounting seat 121 is mounted on the slewing bearing 110. The two sets of link components are both hinged to the mounting seat 121 and are respectively arranged on both sides of the conduit mechanism 130 relatively. The link component includes a plurality of support links 122 extending vertically and hinged in sequence. A first telescopic driving member 123 is provided between the ends of two adjacent support links 122 on the upper side, and a second telescopic driving member 124 is provided between the ends of two adjacent support links 122 on the lower side. Both ends of the support frame 131 are hinged to the support links 122. When it is necessary to control the bending of the medicine delivery hose, control the telescopic movement of each first telescopic driving member 123 and each second telescopic driving member 124 respectively so that the charge loading hose is aligned with the blast hole and extends into the blast hole to deliver the detonating cartridge and the explosive.

[0034] In this embodiment, please refer to Figure 1 and Figure 2 , a connecting seat 125 is hinged to the end of the link component. A hole aligning pipe 126 is mounted on the connecting seat 125. The end of the charge loading hose extends into the hole aligning pipe 126. Since the material of the charge loading hose is relatively soft, the end of the charge loading hose is extended into the hole aligning pipe 126, and the rigid hole aligning pipe 126 is convenient for aligning with the blast hole and extending into the blast hole. A connecting link 127 is hinged between two adjacent support links 122 extending from bottom to top. The connecting link 127 increases the support of the link component and avoids the shaking of the link component. The first telescopic driving member 123 and the second telescopic driving member 124 are both hydraulic cylinders.
