Description

Technical Field

[0001] The utility model relates to the technical field of drilling and blasting, in particular to a rapid positioning device for blasting holes in open-pit coal mines. Background Art

[0002] During the exploitation of open-pit coal mines, drilling and blasting is an essential technological process. When drilling and blasting, the layout of the drilling positions is a key task before drilling. In the existing technology, drilling is generally measured by a meter stick, and then marked with paint at this position. In this process, generally two people need to cooperate. One person measures with the meter stick, and the other person holds the paint bucket to make marks, which is time-consuming and laborious, and the work efficiency is low.

[0003] Publication No.: CN213009752U discloses a rapid positioning device for blasting holes in open-pit coal mines, which designs a special paint extrusion mechanism to make the paint extrusion and marking work fast and convenient. At the same time, as the utility model moves forward, the meter stick inserted on the meter stick rod also unfolds continuously, so that the walking distance can be monitored in real time, and drilling marks can be made in time, greatly improving the work efficiency and worthy of wide promotion and use.

[0004] When the above device is used, the paint is extruded by the up and down movement of the piston arranged in the paint bucket body. However, the reaction force of the compression spring cannot fully offset the gravity of the paint, and it is easy for the paint to slowly leak out, affecting the marking effect. Therefore, a rapid positioning device for blasting holes in open-pit coal mines needs to be proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the paint slowly leaks out from the rubber hose in the existing technology, and to propose a rapid positioning device for blasting holes in open-pit coal mines.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A rapid positioning device for blasting holes in open-pit coal mines includes an installation ring. A paint bucket main body is arranged inside the installation ring. The top end of the paint bucket main body is provided with a feed port, the center of the top end of the paint bucket main body is provided with a threaded hole, the bottom end of the paint bucket main body is provided with a discharge hole, and a material discharging structure for controlling the opening and closing of the discharge hole is arranged inside the paint bucket main body. The bottom end of the installation ring is fixedly installed with an installation rod, and the bottom end of the installation rod is fixedly installed with a meter stick rod. The material discharging structure includes a movable rod movably arranged inside the paint bucket main body. A conical plug is arranged at the bottom end of the movable rod. The conical plug is arranged below the paint bucket main body. The top surface diameter of the conical plug is larger than the discharge hole, and the top surface edge of the conical plug is provided with an arc surface.

[0008] Preferably, a threaded post is coaxially and fixedly connected to the bottom end of the movable rod, and a threaded groove is formed at the top end of the inverted conical plug. The threaded post is threadedly installed in the threaded groove.

[0009] Threads are provided on the outer side wall of the upper section of the movable rod. The upper section of the movable rod is threadedly installed in the threaded hole, and a fixed handle is fixedly installed at the top end of the movable rod.

[0010] The diameter of the discharge hole is larger than the diameter of the movable rod.

[0011] It is used to block the discharge hole. Generally, by rotating the movable rod through the fixed handle, the movable rod drives the inverted conical plug to rotate, so that the top end of the inverted conical plug fits against the bottom end of the paint bucket body, realizing the blocking of the discharge hole. After the device moves to a suitable position, rotate the movable rod in the reverse direction to separate the inverted conical plug from the paint bucket body, and the marked paint flows out of the discharge hole and slowly flows along the outer side wall of the inverted conical plug.

[0012] Preferably, a number of engaging grooves are evenly and equidistantly formed at the top end of the mounting ring, and a number of engaging blocks are evenly and equidistantly fixedly installed at the top end of the outer side wall of the paint bucket body. The engaging grooves correspond to the engaging blocks one by one. The engaging blocks are arranged in the corresponding engaging grooves, and the engaging blocks are fixedly connected to the mounting ring through fastening bolts.

[0013] A number of bolt grooves are formed in the engaging grooves, and a number of threaded through holes are formed in the engaging blocks. The bolt grooves correspond to the threaded through holes one by one. The fastening bolts are sequentially threadedly installed in the threaded through holes and the bolt grooves.

[0014] It is used to install the paint bucket body. Place the paint bucket body into the mounting ring so that the engaging blocks are arranged in the corresponding engaging grooves, then align the bolt grooves with the threaded through holes one by one, and sequentially thread the fastening bolts into the threaded through holes and the bolt grooves, so that the engaging blocks are fixedly connected to the mounting ring through the fastening bolts, which is convenient for installing and disassembling the paint bucket body and facilitating the cleaning of the paint bucket body.

[0015] Preferably, a number of support rods are evenly and equidistantly fixedly installed at the bottom end of the mounting ring, universal wheels are fixedly installed at the bottom ends of the support rods, a pulling rod is fixedly installed at the top end of the mounting ring, and the meter stick inserting rod and the pulling rod are respectively arranged on both sides of the paint bucket body.

[0016] It is used to measure the distance. During operation, the meter stick roll is inserted into the meter stick inserting rod, and the device is moved forward through the pulling rod. At the same time, the meter stick roll is also unfolded, and the walking distance can be monitored at any time.

[0017] The utility model has the following beneficial effects:

[0018] 1. By setting up a material discharging structure, generally, the movable rod is rotated through the fixed handle. The movable rod drives the inverted conical plug to rotate, making the top of the inverted conical plug fit with the bottom end of the paint bucket body, so as to block the discharging hole. After the device moves to a suitable position, the movable rod is rotated in the reverse direction, so that the inverted conical plug is separated from the paint bucket body, and the marked paint flows out from the discharging hole and slowly flows along the outer wall of the inverted conical plug.

[0019] 2. By setting up a clamping groove and a clamping block, the paint bucket body is placed into the mounting ring, so that the clamping block is arranged in the corresponding clamping groove. Then, the bolt groove and the threaded through hole are made to correspond one by one, and the fastening bolts are sequentially threadedly installed in the threaded through hole and the bolt groove, so that the clamping block is fixedly connected to the mounting ring through the fastening bolts, which is convenient for installing and disassembling the paint bucket body and facilitating the cleaning of the paint bucket body.
