Description

Technical Field

[0001] The utility model belongs to the technical field of drilling positioning, and in particular relates to an open-pit mine drilling positioning device. Background Art

[0002] Open-pit mines are to remove the loose soil and surrounding rock covering the upper part of the ore body and its surroundings, transport the waste rock to the spoil dump, and directly mine the ore from the exposed ore body. The perforation blasting is the most important link in the production process of open-pit mines. The quality of perforation blasting directly affects the overall production of open-pit mines. The layout of the drilling position is the first step before drilling. The main factor for whether the drilling rig can be constructed according to the design is the accurate layout of the drilling position. Therefore, the layout of the drilling position is particularly important in open-pit mines. Perforation blasting requires a large number of drilling holes to be laid on the ore body.

[0003] At present, the ground of open-pit mines is often uneven, and it is very difficult to find a flat ground in the open-pit mine. The drilling positioning device in the prior art is usually placed on the ground for positioning by a tripod bracket positioner. Therefore, it is difficult to keep it level during use, so that the positioner is easy to tilt and fall, which easily causes inaccurate positioning and easy damage to the positioning device, bringing unnecessary losses to users.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an open-pit mine drilling positioning device.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0012] In one or more embodiments of the utility model, a pair of slide grooves are excavated in the supporting side plates, and a first limiting pressure plate is arranged in the slide groove. The first limiting pressure plate is fixedly connected to the telescopic plug plate, and is used to support the telescopic plug plate and limit the telescopic plug plate, so that the telescopic plug plate is not easy to fall off, thereby improving the practicality of the device, and also has the function of squeezing the reset spring so that the reset spring can be compressed to generate a rebound force.

[0013] In one or more embodiments of the present invention, a plurality of return springs are fixedly connected between the first limit pressure plate and the supporting side plate, so as to generate a rebound force after being squeezed, so that the return springs can push the first limit pressure plate to rise, thereby facilitating the lifting of the telescopic plug plate and reinserting it into the supporting side plate to reduce space occupancy when not in use.

[0014] In one or more embodiments of the utility model, a plurality of the support side panels are fixed with limiting columns on one side close to the support platform for fixing in the fixing bolt, so that the support side panels are not easy to move, thereby facilitating transportation and storage and reducing space occupancy.

[0018] In one or more embodiments of the present invention, a second limiting pressure plate is fixed on the operating rod, and the second limiting pressure plate is arranged above the lower pressure ring to facilitate the downward pressing of the lower pressure ring and make it difficult for the rotation of the second limiting pressure plate to affect the lower pressure ring and the second return spring, thereby making the rotation of the operating rod less likely to be affected.

[0019] In one or more embodiments of the present invention, a fixing bolt is provided at one end of the support platform close to the multiple supporting side panels for fixing the limiting bar, thereby achieving the function of fixing the support platform.

[0020] Compared with the prior art, the utility model enables the positioning device to remain level on an uneven open-pit mine road surface through the setting of corresponding mechanisms, thereby being less likely to tilt and fall, thereby ensuring the accuracy of positioning and reducing the probability of damage to the positioning device.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, an open-pit mine drilling positioning device in one embodiment of the utility model includes: a fixed platform 1, a stretching support mechanism 2 and a positioning marking mechanism 3.

[0032] like Figures 1 to 5 As shown, a plurality of intelligent level gauges 101 are installed on the fixed platform 1 to facilitate the staff to observe the level. The stretching support mechanism 2 is installed on the fixed platform 1, and the stretching support mechanism 2 includes a plurality of supporting side panels 201, which are used to provide support force for the fixed platform 1 and increase space for retracting the telescopic plug plate 203. The plurality of supporting side panels 201 are rotatably connected with fixed shaft rods 202, and the plurality of fixed shaft rods 202 are fixed on the fixed platform 1, so that the telescopic plug plate 203 is not easy to fall off, and can also rotate freely, thereby facilitating the staff to stretch the plurality of supporting side panels 201 to form support for the fixed platform 1, thereby improving the stability of the support.

[0033] like Figure 5 As shown, a telescopic plug plate 203 is inserted into the supporting side plate 201 to increase the height of the fixing platform 1 and improve the practicability of the device.

[0034] like Figure 1 to Figure 2As shown, a fixing frame 204 is fixed on each of the plurality of supporting side plates 201 to support the locking screw 205, so that the locking screw 205 is not likely to fall off. The locking screw 205 is threadedly connected to the fixing frame 204, so that the locking screw 205 can be close to or away from the telescopic plugboard 203 when rotating, thereby achieving the extrusion and fixing of the telescopic plugboard 203 and the distance from and release of the telescopic plugboard 203, making it convenient to control the extension distance of the telescopic plugboard 203 and to adjust the level of the fixing platform 1.

[0035] like Figures 1 to 5 As shown, a pair of slide grooves are bored in the supporting side plate 201, and a first limiting pressure plate 206 is arranged in the slide groove. The first limiting pressure plate 206 is fixedly connected to the telescopic plug plate 203, and is used for supporting the telescopic plug plate 203 and limiting the telescopic plug plate 203, so that the telescopic plug plate 203 is not easy to fall off, thereby improving the practicality of the device, and also has the function of squeezing the reset spring 207, so that the reset spring 207 can be compressed to generate a rebound force.

[0036] Among them, a plurality of return springs 207 are fixedly connected between the first limit pressure plate 206 and the supporting side plate 201, which are used to generate a rebound force after being squeezed, so that the return spring 207 can push the first limit pressure plate 206 to rise, thereby facilitating the lifting of the telescopic plug plate 203 and inserting it into the supporting side plate 201 again, so as to reduce the space occupied when not in use.

[0037] like Figure 6 As shown, a plurality of support side panels 201 are fixed with limiting bars 208 on one side close to the support platform 301 for fixing in the fixing bolts 312, so that the support side panels 201 are not easy to move, thereby facilitating transportation and storage and reducing space occupancy.

[0038] like Figures 1 to 4 As shown, the positioning marking mechanism 3 is installed between a plurality of supporting side plates 201, and the positioning marking mechanism 3 includes a support platform 301, which is used to support a positioning adjustment ball 302, so that the positioning adjustment ball 302 can be easily rotated, thereby facilitating the adjustment of the angle of the marking rotating rod 305. The positioning adjustment ball 302 is rotatably mounted on the support platform 301, so as to facilitate the adjustment of the angle of the marking rotating rod 305, and a control rod 303 is fixed on the positioning adjustment ball 302, and an operating rod 304 is inserted in the control rod 303.

[0039] The lower end of the operating rod 304 is fixedly connected with a marking rotating rod 305 for contacting the ground after rotation, thereby facilitating positioning marking.

[0040] In addition, a round wheel 306 is sleeved on the upper end of the operating rod 304, and a plurality of connecting thin rods 307 are fixedly connected between the operating rod 304 and the round wheel 306, which are used to drive the rotation of the operating rod 304, thereby driving the marking rotating rod 305, and also facilitate the staff to press the operating rod 304 downward, so that the marking rotating rod 305 can leave a mark on the ground, achieving the effect of positioning the mark. A plurality of supporting columns 308 are fixedly connected between the support platform 301 and the fixed platform 1, which are used to support the support platform 301, so that the support platform 301 is not easy to fall off and shake, and play a supporting role to maintain the stability of the device.

[0041] like Figures 1 to 4 As shown, a circular groove is bored in the control rod 303, and a lower pressing ring 310 is arranged in the circular groove, which is used to press down the second reset spring 311 and push up the second limit pressure plate 309. A plurality of second reset springs 311 are fixedly connected between the lower pressing ring 310 and the control rod 303, which are used to generate a rebound force after being squeezed, thereby assisting in pushing the operating rod 304 up to achieve the reset effect.

[0042] like Figures 1 to 4 As shown, a second limiting pressure plate 309 is fixed on the operating rod 304, and the second limiting pressure plate 309 is arranged above the lower pressing ring 310, for conveniently pressing the lower pressing ring 310 downward, and makes it difficult for the rotation of the second limiting pressure plate 309 to affect the lower pressing ring 310 and the second return spring 311, thereby making it difficult for the rotation of the operating rod 304 to be affected. A fixing bolt 312 is arranged at one end of the support platform 301 close to the multiple supporting side plates 201, for fixing the limiting bar 208, so as to achieve the function of fixing the support platform 301.

[0043] When in use, the supporting side plates 201 are first rotated so that the multiple supporting side plates 201 can be stretched out to support the fixed platform 1, and then the locking screw 205 is rotated so that the locking screw 205 no longer squeezes the telescopic plug plate 203, and then the telescopic plug plate 203 is pulled so that the fixed platform 1 is at a suitable height, and then the locking screw 205 is rotated so that the locking screw 205 presses the telescopic plug plate 203 to achieve the function of fixing the extended length of the telescopic plug plate 203, and the level of the fixed platform 1 is ensured by observing the intelligent level 101;

[0044] Then rotate the operating rod 304 to adjust the position so that the positioning and direction adjustment ball 302 can rotate in the support platform 301, and then press down the connecting thin rod 307 so that the operating rod 304 can drive the marking rotating rod 305 to descend, so that the marking rotating rod 305 contacts the ground, and then rotate the round wheel 306 so that the operating rod 304 can drive the marking rotating rod 305 to rotate, so that a mark can be left on the ground, achieving the positioning effect and facilitating subsequent construction.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
