Description

Technical Field

[0001] The present invention relates to the technical field of gear boxes, and in particular to a ground anchor fastening structure for connecting an articulated ground anchor to a gear box. Background Art

[0002] In mining equipment, some gearboxes are connected to the platform using an articulated anchor connection. Specifically, the platform is equipped with two symmetrical pin seats, with the bottom of the gearbox at least partially positioned between the two pin seats. A pin hole is provided at the bottom of the gearbox, into which a pin is inserted. The two ends of the pin are connected to the two pin seats. This effectively secures the gearbox to the platform while allowing for a certain amount of circumferential movement around the pin, relieving stress generated when the gearbox is about to deform under load. This connection method provides a highly flexible connection.

[0003] In actual use, in order to ensure that the gearbox can be easily and accurately installed on the platform, the pin hole at the bottom of the gearbox and the pin are usually installed with a clearance fit. Due to the gap between the pin hole and the pin, the gearbox may vibrate, move, deform, etc. Figure 1 and Figure 2 As shown, in order to eliminate the influence of the gap between the pin shaft hole and the pin shaft at the bottom of the gear box, after the gear box 1 is connected to the pin shaft seat 2 of the platform through the pin shaft 3, a set of wedge blocks 4 will be added to the bottom of the gear box 1, that is, after the gear box 1 is lifted, the wedge blocks 4 are inserted between the bottom of the gear box 1 and the platform, and the gear box 1 is squeezed upward and lifted with the help of the wedge blocks 4, so that the pin shaft 3 maintains close contact with the pin shaft hole at the bottom of the gear box, thereby eliminating the gap, and then, a top block 5 is set behind the wedge block 4, and the top block 5 is welded to the platform at the same time, thereby fixing the position of the wedge block 4.

[0004] However, in actual use, it was found that the wedge block 4 would deform due to long-term compression. At the same time, the pin hole at the bottom of the gearbox and the pin would also deform and wear due to factors such as force and friction, causing the gap between the pin and the pin hole to gradually increase, affecting the normal operation of the gearbox. Moreover, under the current positioning method using wedge blocks, the staff cannot regularly adjust the position between the pin hole and the pin. Ultimately, when the gap between the two is too large, the wedge block 4 and the top block 5 welded to the platform at the back can only be removed. After the gearbox 1 is re-installed, the wedge block 4 and the top block 5 are re-welded to the platform. It can be seen that the existing fixing method using wedge blocks is not conducive to subsequent position adjustment. At the same time, the fixing method is time-consuming and labor-intensive, and it is inconvenient for the staff to adjust and operate. Summary of the Invention

[0005] In order to solve some or all of the technical problems existing in the above-mentioned prior art, the present invention provides a ground anchor fastening structure for connecting an articulated ground anchor to a gearbox.

[0029] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In one embodiment of the present invention, a ground anchor fastening structure for an articulated ground anchor connected to a gearbox is provided. With the help of this structure, the gearbox can be fixed to the platform. Moreover, during the use of the gearbox, even if deformation or wear occurs between the pin shaft and the pin shaft hole, under the structure in this embodiment, the position of the gearbox can be regularly tightened by tightening the nut.

[0032] Specifically, if Figure 3 As shown, the anchor fastening structure in this embodiment includes: a connecting plate 11 , a pin seat 17 , and a pin 18 .

[0033] Among them, the number of connecting plates 11 is two, and the two connecting plates 11 are symmetrically fixed on both sides of the bottom of the gear box, and the two connecting plates 11 are respectively provided with through holes passing through along the height direction of the platform; the number of pin seats 17 is two, and the two pin seats 17 are respectively symmetrically fixed on the platform, and the two pin seats 17 are respectively arranged corresponding to the two connecting plates 11, and the bottom of the gear box can be placed between the two pin seats 17, and the top of the pin seat 17 is provided with a stud 12 extending upward along the height direction of the platform; the pin shaft 18 can pass through the pin shaft hole at the bottom of the gear box, and the two ends of the pin shaft 18 can be respectively connected to the pin shaft seats 17 on both sides of the bottom of the gear box.

[0034] Furthermore, the stud 12 on the pin seat 17 passes through the through hole of the connecting plate 11, and one end of the stud 12 extending beyond the through hole is threadedly connected to a fastening nut 14, which can apply a force to the connecting plate 11 to make the connecting plate 11 close to the pin seat 17.

[0035] For example, the connecting plates 11 can be fixed to both sides of the bottom of the gear box in advance by welding or the like, and the pin shaft seat 17 can also be fixed to the platform by welding or the like.

[0036] During actual installation, the bottom of the gearbox can be moved between the two pin seats 17 with the help of lifting equipment. At the same time, the studs 12 on the pin seats 17 on both sides are respectively passed through the through holes of the two connecting plates 11 at the bottom of the gearbox. After the gearbox is moved to the appropriate position, the pin 18 is passed through the pin seats 17 on both sides and the pin holes at the bottom of the gearbox in turn to facilitate the preliminary positioning of the gearbox. After that, the fastening nut 14 is screwed onto the stud 12. By tightening the fastening nut 14, the connecting plate 11 is brought close to the pin seat 17, thereby pressing the gearbox downward. After being fully tightened, the pin 18 can form a close contact with the pin hole at the bottom of the gearbox, eliminating the gap between the pin 18 and the pin hole, which can ensure that the gearbox can work normally.

[0037] During use, when deformation or wear occurs between the pin shaft 18 and the pin shaft hole at the bottom of the gear box, or when the fastening nut 14 becomes loose due to vibration, the staff can regularly tighten the fastening nut 14 to achieve regular fixation of the gear box.

[0038] Furthermore, in order to improve the fixing effect of the fastening nut 14 , in this embodiment, a round nut locking washer 16 and a round nut 15 are sequentially sleeved on the stud 12 on the side of the fastening nut 14 away from the connecting plate 11 .

[0039] During the actual installation process, after the fastening nut 14 is tightened and abuts against the connecting plate 11 , the round nut locking washer 16 and the round nut 15 may be sequentially installed on the stud 12 to lock the fastening nut 14 .

[0040] Preferably, a washer 13 is further provided on the stud 12 between the fastening nut 14 and the connecting plate 11. Thus, with the help of the washer 13, the connecting surface of the two can be protected from being scratched.

[0041] In order to ensure that the fastening nut 14 can be evenly abutted against the connecting plate 11, in this embodiment, an abutment surface perpendicular to the axial direction of the stud 12 is provided on the side of the connecting plate 11 close to the fastening nut 14, and the washer 13 can abut against the abutment surface.

[0042] That is to say, the top of the connecting plate 11 has an abutment surface perpendicular to the axial direction of the stud 12. During the actual installation process, after the washer 13 is fitted to the abutment surface, the contact surface between the fastening nut 14 and the washer 13 can always be perpendicular to the axial direction of the stud 12, so that the fastening nut 14 can apply uniform extrusion force to the washer 13.

[0043] In addition, the axis of the stud 12 and the axis of the pin 18 are substantially located in the same plane.

[0044] Therefore, after the fastening nut 14 is tightened and abuts against the connecting plate 11, it can be ensured that the top of the pin 18 is stressed and effectively abuts against the pin hole at the bottom of the gear box.

[0045] Therefore, the structure in this embodiment has the following advantages:

[0046] (1) During the installation of the gearbox, the gearbox can be pressed downward by tightening the fastening nut, so that the pin can abut against the pin hole at the bottom of the gearbox, eliminating the gap between the two. Under the action of the gravity of the gearbox, this fixing method is easier to achieve than lifting the gearbox upward in the past;

[0047] (2) The gap between the pin and the pin hole can be eliminated by tightening the fastening nut and the lock nut, without setting a wedge block and a top block, which can simplify the installation steps and make the installation of the gearbox more convenient;

[0048] (3) During the subsequent position adjustment, the staff only needs to tighten the fastening nut and the lock nut regularly, which can conveniently and quickly eliminate the gap between the pin and the pin hole caused by deformation and wear at any time;

[0049] (4) The structure in this embodiment can not only realize the foot fastening of a newly installed gearbox, but also can be used to modify the gearbox in use, and can also realize the regular fastening of the articulated foot connection gearbox foot.
