Description

Technical Field

[0001] The utility model belongs to the technical field of drilling equipment, in particular to a YZ series drilling rig crawler shoe shaft installation and disassembly device. Background Art

[0002] The rotary drill is the main perforating equipment for open-pit mining. The rotary drill mainly uses crawler tracks. It is characterized by good performance, adaptability to various ground conditions, and stability, so as to meet the different working needs of the drill. It is the main working mechanism of the drill. The track shoe assembly of the rotary drill is composed of several track shoes. Each track shoe is connected by a track plate shaft and fixed with a stop pin on the outside of the track plate shaft to prevent it from jumping out. Due to the long-term running of the drill track shoes, the harsh working environment, and the uneven ore, the track shoes and track plate shafts will be severely worn. In the long run, the track shoes will break, the track plate shaft will be broken and deformed, and the track plate shaft stop pin will be missing, resulting in the track plate shaft jumping out. Therefore, it needs to be replaced. If the replacement is not timely, the track shoes will be loose in serious cases. There is no correct and reasonable method to replace the track plate shaft. Usually, the track plate with the missing track plate shaft is returned to the middle position, and then the two track plates that have sprung out of the track plate shaft are tied up with the auxiliary winch rope on the drilling rig, and then hoisted with the auxiliary winch rope. It is cumbersome to use, and the safety factor is unstable, which is easy to cause personal injury accidents. Another method is that if the track plate is loose, the track plate can be returned to the bottom of the driving wheel, and with the help of a short-pointed crowbar, it is inserted into the track plate shaft hole, and repeatedly turned to confirm that the track plate shaft can be strung in, and then the two track plates are welded with electric welding, and then the crowbar is thrown out and the track plate shaft is inserted. It is very difficult to handle the track plate shaft. It requires 2 people. Sometimes the handling of the track plate shaft takes more than 2-3 hours, which is labor-intensive and time-consuming. At the same time, it will bring safety hazards, affect the drilling rig's perforation operation, and increase the start-up of the equipment. Summary of the invention

[0003] The utility model aims to provide a YZ series drilling rig crawler shoe shaft installation and disassembly device, which is convenient for installation and disassembly, saves time and effort, reduces the failure rate and improves work efficiency.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] The utility model discloses a YZ series drilling rig crawler shoe shaft installation and disassembly device, which is characterized by comprising two symmetrically arranged vertical fixing plates, two hooks respectively welded to the bottom of the two vertical fixing plates, a sliding hole arranged at the upper part of each vertical fixing plate, an adjustment bolt hole arranged at the middle part of each vertical fixing plate, a limit rod passing through the two sliding holes and slidably connected to the two vertical fixing plates, and an adjustment bolt threadedly connected to the two adjustment bolt holes.

[0006] The two curved hooks are two oblique triangular hooks.

[0007] Advantages of the utility model:

[0008] The utility model discloses a YZ series drilling rig crawler plate shaft installation and disassembly device, which has low manufacturing cost and is convenient to install and disassemble.

It not only greatly improves the safety factor of replacing the track plate shaft, reduces the time of replacing the track plate shaft, improves the punching efficiency, but also reduces the labor intensity of the post driver; it effectively avoids the accident of injury caused by the auxiliary winch hook and the broken steel rope, effectively prevents the phenomenon of waist sprain caused by the break of the crowbar, and ensures the smooth production of the drilling rig. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0010] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.

[0011] like Figure 1 As shown, the YZ series drilling rig track shoe shaft installation and disassembly device of the utility model is characterized in that it includes two symmetrically arranged vertical fixing plates 1, two hooks 4 respectively welded to the bottom of the two vertical fixing plates 1, a sliding hole arranged at the upper part of each vertical fixing plate 1, an adjustment bolt hole arranged in the middle part of each vertical fixing plate 1, a limit rod 2 passing through the two sliding holes and slidably connected to the two vertical fixing plates, and an adjustment bolt 3 threadedly connected to the two adjustment bolt holes.

[0012] The two hooks 4 are two oblique triangular hooks.

[0013] The utility model discloses a device for installing and removing the track plate shaft of a YZ series drilling rig. The two hooks 4 are two oblique triangular hooks. The two vertical fixing plates 1 have sliding holes on the upper part and adjustment bolt holes in the middle part. The two vertical fixing plates 1 are erected and welded to the upper part of the triangular hooks 4. When replacing or removing the track shaft, the welded bracket (two vertical fixing plates 1 and two hooks 4) is placed in the track plate slot near the track plate shaft to be replaced or removed, and the track plate slot is clamped by the hooks 4. The limit rod 2 is installed into the limit hole on the upper part of the vertical fixing plate 1, and the adjustment bolt 3 is screwed into the adjustment bolt hole in the middle part. At this time, the nut is adjusted, and the two vertical fixing plates 1 produce relative movement along the adjustment bolt 3 under the rotation of the adjustment bolt 3 and the limit of the limit rod 2. The distance between the two track plates clamped by the hooks 4 is gradually shortened until the track plate shaft is taken out. The device is easy to install and disassemble, saves time and effort, reduces safety accidents, reduces the labor intensity of operators, and improves equipment start-up. Other drilling rigs 45R and YZ series can be improved and installed based on this reference.

[0014] The utility model discloses a YZ series drilling rig crawler plate shaft installation and disassembly device, which has low manufacturing cost and is convenient to install and disassemble. The installation of the track plate shaft improves the work efficiency by more than three times and has stable and reliable operation effect. It not only greatly improves the safety factor of replacing the track plate shaft, reduces the time of replacing the track plate shaft, improves the punching efficiency, but also reduces the labor intensity of the post driver; it effectively avoids the accident of injury caused by the auxiliary winch hook and the broken steel rope, effectively prevents the phenomenon of waist sprain caused by the break of the crowbar, and ensures the smooth production of the drilling rig.
