Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and more specifically, to a universal rigid connection device for narrow-gauge mining transport vehicles. Background Technology

[0002] When connecting existing mining transport vehicles, a connection device with a universal joint structure is usually used to achieve quick connection between transport vehicles and adapt to working conditions such as uphill, downhill and turning in underground roadway flatbed transport.

[0003] Patent CN222335086U discloses a universal rigid connection device for narrow-gauge mining vehicles. This device connects to the vehicle via a connector, with a universal ring and ball joint working together to ensure omnidirectional movement. Two connecting sleeves are connected by a connecting rod, thus achieving a universal rigid connection between adjacent vehicles. However, the connecting rod between the two connecting sleeves in this universal rigid connection device has a fixed length. Therefore, this device is no longer suitable when the overall length of the universal rigid connection device needs to be adjusted to adapt to mining transportation conditions. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a universal rigid connection device for narrow-gauge mining vehicles.

[0005] A universal rigid connection device for narrow-gauge mining vehicles includes:

[0006] Two symmetrically arranged connecting components and a length adjustment component arranged between the two connecting components;

[0007] The connecting component includes a connecting sleeve for connecting to a transport vehicle, a connecting cylinder connected to the connecting sleeve, a universal ring located inside the connecting cylinder, a ball head located inside the universal ring, and a connecting rod connected to the ball head;

[0008] The length adjustment component is used to adjust the distance between the two connecting rods.

[0009] Furthermore, the connecting sleeve and the connecting cylinder are fixedly connected by a connecting block.

[0010] Furthermore, the length adjustment component is an adjustable sleeve fitted onto the two connecting rods;

[0011] The inner diameter of the sleeve is adapted to the outer diameter of the connecting rod; the sleeve has a plurality of first through holes, and correspondingly, each connecting rod has a plurality of second through holes; the first through holes and second through holes at different positions are connected by bolts after they overlap, which can form different distances between the two connecting rods.

[0012] Furthermore, the connecting rod is a round rod, and the sleeve is an inner hollow round tube.

[0013] Furthermore, each of the connecting rods is fixedly connected to an L-shaped adjusting rod, the L-shaped adjusting rod comprising a connecting section and an adjusting section, the middle part of the connecting section being fixedly connected to the end of the connecting rod; the adjusting section is provided with external threads;

[0014] The two adjustable sections are adjustablely connected to a length adjustment component.

[0015] Furthermore, the two L-shaped adjusting rods are 180° rotationally symmetrical.

[0016] Furthermore, the length adjustment component includes two limiting plates, each limiting plate having two third through holes, a support cylinder being arranged between the two limiting plates, and the two adjustment sections respectively passing through the corresponding third through holes; an anti-loosening nut is also arranged on the outside of each limiting plate.

[0017] Furthermore, the adjusting section of one of the L-shaped adjusting rods passes through two third through holes on the same side of the two limiting plates and one of the supporting cylinders, while the adjusting section of the other L-shaped adjusting rod passes through two third through holes on the other side of the two limiting plates and the other supporting cylinder.

[0018] Furthermore, the anti-loosening nut is threaded onto the adjusting section of the L-shaped adjusting rod, and different connection positions of the anti-loosening nut are used to create different distances between the two connecting rods.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This universal rigid connection device for narrow-gauge mining vehicles involves simultaneously fitting a sleeve onto the free ends of two connecting rods. Depending on the working conditions, the first and second through holes are aligned, and then bolts are used to tighten them. By changing the effective extension length of the two connecting rods, the overall length of the universal rigid connection device can be adjusted without disassembling the device, while both ends remain connected to the narrow-gauge mining vehicle. This saves time on disassembly and reinstallation.

[0021] This narrow-gauge transport vehicle for mining uses a universal rigid connection device with two L-shaped adjusting rods fixed to the ends of the connecting rods. Anti-loosening nuts are provided on the outer sides of the two limiting plates. The external thread of the adjusting section passes through the third through hole 91 on the same side of the limiting plate and the support cylinder. By rotating the position of the anti-loosening nut on the adjusting section, the relative distance between the two connecting rods can be changed, thereby realizing the overall length adjustment of the device. The operation is convenient and can be completed without disassembling the device from the transport vehicle. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1:

[0037] like Figures 1-2As shown, this embodiment provides a universal rigid connection device for a narrow-gauge mining transport vehicle, including two symmetrically arranged connecting components and a length adjustment component disposed between the two connecting components. The connecting components include a connecting sleeve 1 for connecting to the transport vehicle, a connecting cylinder 2 connected to the connecting sleeve 1, a universal ring 3 located within the connecting cylinder 2, a ball joint 4 located within the universal ring 3, and a connecting rod 5 connected to the ball joint 4. The connecting sleeve 1 and the connecting cylinder 2 are fixedly connected by a connecting block 6. The connecting sleeve 1 has a connecting hole for connecting to the transport vehicle. The length adjustment component is used to adjust the distance between the two connecting rods 5, thereby allowing the overall length of the connecting device to be adjusted to meet the needs of mining transport without replacing the connecting device or removing it from the transport vehicle.

[0038] In this embodiment, the length adjustment component is a sleeve 7 that is adjustablely fitted onto the two connecting rods 5. The connecting rods 5 are round rods, and the sleeve 4 is an inner hollow round tube.

[0039] Specifically, the inner diameter of the sleeve 7 is matched with the outer diameter of the connecting rod 5; the sleeve 7 has several first through holes 71, and correspondingly, each connecting rod 5 has several second through holes 51; the first through holes 71 and second through holes 51 at different positions are connected by bolts, which can form different distances between the two connecting rods 5. In other words, by connecting the sleeve 7 at different positions of the two connecting rods 5, and fixing the sleeve 7 to the corresponding positions of the connecting rods 5 with bolts, a universal rigid connection device of different lengths is formed, thereby adapting to the length requirements of the universal rigid connection device under different working conditions in mining transportation.

[0040] The universal rigid connection device for mining narrow-gauge transport vehicles provided in this embodiment involves simultaneously fitting the sleeve 7 onto the free ends of the two connecting rods 5, selecting the appropriate positions of the first through hole 71 and the second through hole 51 according to the working conditions to make them coincide, and then locking them with bolts. That is, by changing the effective extension length of the two connecting rods 5, the overall length of the universal rigid connection device can be adjusted without disassembling the device, while both ends of the device are still connected to the mining narrow-gauge transport vehicle, thus saving the time of disassembly and reinstallation.

[0041] In this embodiment, the universal motion of the device is transmitted step by step by the connecting sleeve 1, connecting block 6, connecting cylinder 2, universal ring 3, ball head 4, and connecting rod 5; the ball head 4 can swing in multiple directions within the universal ring 3, thereby adapting to the movement of the mining narrow-gauge transport vehicle when going uphill, downhill, and turning.

[0042] Example 2:

[0043] In this embodiment, the difference from Embodiment 1 is that each connecting rod 5 is fixedly connected to an L-shaped adjusting rod 8, and the two L-shaped adjusting rods 8 are 180° rotationally symmetrical. Specifically, as shown... Figures 3-5As shown, the L-shaped adjusting rod 8 includes a connecting section 81 and an adjusting section 82. The middle part of the connecting section 81 is fixed to the end of the connecting rod 5, and the adjusting section 82 is provided with external threads. The two adjusting sections 82 are adjustablely connected to a length adjusting component.

[0044] In this embodiment, the length adjustment component includes two limiting plates 9, each limiting plate 9 having two symmetrical third through holes 91, a support cylinder 10 is arranged between the two limiting plates 9, and the adjusting sections 82 of the two L-shaped adjusting rods 8 pass through the corresponding third through holes 91; anti-loosening nuts 11 are also arranged on the outside of each limiting plate 9.

[0045] More specifically, the adjusting section 82 of one L-shaped adjusting rod 8 passes through two third through holes 91 on the same side of the two limiting plates 9 and one of the support cylinders 10. The support cylinder 10 is located between the two limiting plates 9 and on the same side as the aforementioned two third through holes 91. The adjusting section 82 of the other L-shaped adjusting rod 8 passes through two third through holes 91 on the other side of the two limiting plates 9 and another support cylinder 10. A lock nut 11 is threaded onto the adjusting section 82 of the L-shaped adjusting rod 8. Different connection positions of the lock nut 11 are used to create different distances between the two connecting rods 5, such as... Figure 3 and Figure 4 As shown, this results in the formation of universal rigid connection devices of different lengths, which can meet the length requirements of universal rigid connection devices under different working conditions in mining transportation.

[0046] The universal rigid connection device for narrow-gauge mining transport vehicles provided in this embodiment has two L-shaped adjusting rods 8 fixed to the ends of connecting rods 5 respectively. Anti-loosening nuts are provided on the outer sides of the two limiting plates 9 respectively. The external thread of the adjusting section 82 passes through the third through hole 91 and the support cylinder 10 on the same side of the limiting plate 9. By rotating the position of the anti-loosening nut 11 on the adjusting section 82, the relative distance between the two connecting rods 5 can be changed, thereby realizing the overall length adjustment of the device. The operation is convenient and can be completed without disassembling the device from the transport vehicle.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
