Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a mine gob-side lane retaining material vehicle pushing device. Background Art

[0002] When it is necessary to use filling materials for mine-side tunnels, transport carts are usually used to transfer bagged filling materials. However, when transporting bagged filling materials, the transport carts in the prior art are limited by the height of the placement area for placing bagged filling materials. The number of bagged filling materials that can be transferred by the transport carts each time is limited. When a large amount of bagged filling materials for mine-side tunnels is needed, multiple transportations are usually required. If the height of the fence used to form the placement area is directly increased, space will be wasted when transporting a small amount of bagged filling materials for mine-side tunnels.

[0003] On the other hand, due to the height limitation of the placement area of ​​the transport cart for placing bagged filling materials, if high-height bagged filling materials are placed in the placement area at one time, the bagged filling materials above may easily fall from the top of the cart when the transport cart passes through bumpy roads. The fallen bagged filling materials need to be moved back to the cart, which is time-consuming and labor-intensive. Utility Model Content

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 4 As shown, an embodiment of the utility model provides a mining goaf-side tunnel material vehicle pushing device, comprising a panel group 10, a drive unit 20 and a load-bearing base plate 30 with a moving roller 40 at the bottom. The panel group 10 is arranged above the load-bearing base plate 30 and forms a placement area for placing materials together with the load-bearing base plate 30; the drive unit 20 is arranged on one side of the load-bearing base plate 30 and is driven and connected to the panel group 10 to drive the panel group 10 to rise and fall on the load-bearing base plate 30.

[0039] In this embodiment, when it is necessary to transfer the bagged filling materials, the position of the enclosure group 10 on the load-bearing base plate 30 can be adjusted according to factors such as the number of bagged filling materials to be transferred and the stacking height, so as to adjust the vertical height position of the top of the placement area, thereby achieving adaptive adjustment of the number of bagged filling materials that can be stacked in the placement area, avoiding the situation in the prior art where the transport trolley is limited by the height of the placement area, resulting in a limited maximum number of bagged filling materials that can be placed, and avoiding the situation in the prior art where the placement area of ​​the transport trolley is made too high and space is easily wasted, thereby improving the applicability of the mine-used goaf-retaining tunnel material vehicle pushing device.

[0040] like Figure 1 and Figure 2As shown, the driving part 20 includes a driving component and a reinforcement support plate 21 fixedly arranged on one side of the enclosure group 10. The reinforcement support plate 21 has a lifting groove 211 extending in the vertical direction. The driving component is arranged on the reinforcement support plate 21 and includes a lifting seat 22 passed through the lifting groove 211. The lifting seat 22 is limited by the inner wall of the lifting groove 211 and is fixedly connected to the enclosure group 10.

[0041] With this arrangement, the driving assembly drives the lifting seat 22 in the lifting slot 211, thereby achieving the lifting and lowering adjustment of the panel assembly 10, improving the convenience of adjustment. In addition, the lifting seat 22 cooperates with the inner wall limit of the lifting slot 211 to guide the lifting of the panel assembly 10, ensuring the reliability and stability of the lifting of the panel assembly 10.

[0042] Specifically, the driving assembly also includes a fixed screw 23 and a fixed block 24. The fixed block 24 is partially arranged on the reinforcement support plate 21. The fixed screw 23 passes through the fixed block 24 that protrudes from the reinforcement support plate 21. The extension direction of the fixed screw 23 is parallel to the extension direction of the lifting groove 211. The lifting seat 22 has a first threaded hole 221 facing the fixed screw 23, and one end of the fixed screw 23 is threadedly connected to the first threaded hole 221.

[0043] With such a configuration, the operator can adjust the lifting seat 22 by rotating the fixing screw 23 , which is also beneficial for avoiding the problem of the lifting seat 22 rising and falling on its own, thereby ensuring the reliability and stability of the adjustment.

[0044] It is understandable that the operator can rotate and adjust the fixing screw 23 to drive the lifting base 22 to move up and down while the fixing screw 23 is connected to the first threaded hole 221, or the operator can first remove the fixing screw 23 from the first threaded hole 221, and then re-thread the fixing screw 23 and the first threaded hole 221 after manually lifting the lifting base 22 to a specified height.

[0045] like Figure 2 As shown, the inner wall of the lifting groove 211 has a guide groove 212, and the lifting seat 22 has a corresponding guide protrusion 222, which is engaged with the guide groove 212. This arrangement helps prevent the lifting seat 22 from falling out of the lifting groove 211 and further guides the lifting seat 22 as it moves up and down within the lifting groove 211.

[0046] like Figure 1 As shown, the mining goaf-side tunnel material vehicle pushing device also includes a hand-pushing part 50 arranged on one side of the load-bearing base plate 30, the hand-pushing part 50 includes two support rods 51 fixedly arranged on the load-bearing base plate 30 and an anti-slip pushing rod 52 arranged between the tops of the two support rods 51, and the driving part 20 is fixedly arranged between the two support rods 51.

[0047] This arrangement makes it easier for operators to push the mining goaf-side tunnel material vehicle pushing device to the desired position, improves the convenience of transportation, and is also beneficial to the limiting installation of the drive part 20.

[0048] Specifically, the panel assembly 10 includes a baffle 11 and a plurality of lifting panels 12. The plurality of lifting panels 12 surround and form a storage area with an opening. The baffle 11 is detachably mounted at the opening of the storage area. This arrangement facilitates the operator to load or unload the bagged filling material from the opening of the storage area.

[0049] Furthermore, a support seat 303 is provided on the top of the load-bearing base plate 30 , and a corresponding support seat 303 is provided under any lifting enclosure 12 , and the lifting enclosure 12 is slidably connected to the corresponding support seat 303 .

[0050] With this arrangement, the lifting panel 12 can be effectively supported by the support seat 303, and the lifting panel 12 can be guided in the lifting and lowering direction through its driving connection with the lifting panel 12, thereby preventing the lifting panel 12 from shaking, deflecting, etc. during the lifting process.

[0051] It can be understood that the lifting panel 12 and the support seat 303 can be installed in a plug-in manner, that is, one of the lifting panel 12 and the support seat 303 has a plug-in groove, and the other has a plug-in protrusion, and the plug-in protrusion can be slidably limited and installed in the plug-in groove. Through the cooperation of the two, the lifting panel 12 can be guided to rise and fall.

[0052] In this embodiment, the placement area formed by the enclosure group 10 and the load-bearing base plate 30 is a rectangular area, and the multiple lifting enclosures 12 include two side panels 121 and a lifting plate 122. The two side panels 121 are symmetrically arranged on the left and right sides of the load-bearing base plate 30, and the two ends of the lifting plate 122 are respectively fixedly connected to the ends of the two side panels 121 close to the driving part 20. The driving part 20 is driven and connected to the lifting plate 122. The side of the load-bearing base plate 30 located on the opening side of the placement area is the installation side. The two side panels 121 extend to the installation side away from the ends of the driving part 20. The baffle 11 is detachably arranged on the installation side. When the baffle 11 is installed on the installation side, the ends of the two side panels 121 away from the driving part 20 are both abutted or fitted with the baffle 11. There are three support seats 303, and the three support seats 303 are respectively used to support the two side panels 121 and one lifting plate 122 and are slidably connected to the corresponding lifting enclosure 12. With this arrangement, the baffle 11 can be used to seal the opening of the placement area, preventing the bagged filling material from falling out of the opening due to problems such as transportation bumps after placement, thereby ensuring the reliability of transportation.

[0053] Preferably, the height of the baffle 11 is greater than the height of the lifting enclosure 12. The top of the baffle 11 after installation should be flush with the top of the lifting enclosure 12 when it is raised to its highest point, or there should be a small height difference. It is understood that the baffle 11 can also be selected or replaced according to the actual top height of the placement area.

[0054] It is understandable that the shape of the placement area formed by the enclosure panel group 10 and the load-bearing base plate 30 can be adjusted according to actual conditions.

[0055] like Figure 1 and Figure 4 As shown, the baffle 11 is installed perpendicular to the two side panels 121. The installation side has a mounting groove 301 extending along the installation direction. A limiting protrusion 111 is provided on the bottom of one side of the baffle 11. The limiting protrusion 111 engages with the inner wall of the mounting groove 301. This arrangement allows for guided installation of the baffle 11, ensuring reliable and stable installation.

[0056] Specifically, in the installation direction of the baffle 11, a limiting block 302 is provided at the end opening of the installation groove 301, and the baffle 11 cooperates with the limiting block 302 to stop. The mining-used goaf-side tunnel material vehicle pushing device also includes a bolt 61, and the baffle 11 and the limiting block 302 are detachably connected by the bolt 61.

[0057] In this way, the baffle 11 is stopped by the limit block 302 to define the installation position of the baffle 11. Figure 3 and Figure 4 As shown, the baffle 11 has a second threaded hole 112 on the side facing the limit block 302. When fixing the baffle 11, the bolt member 61 passes through the limit block 302 and is threadedly connected to the second threaded hole 112 to fix the baffle 11. The bolt member 61 realizes a detachable threaded connection between the baffle 11 and the limit block 302, thereby avoiding instability problems such as the baffle 11 sliding out after installation, thereby ensuring the stability and reliability of the installation of the baffle 11.

[0058] In summary, the present invention provides a device for pushing a material vehicle along the goaf of a mine. When the device is used to transport the material along the goaf of a mine, the bagged filling material can be stacked in the placement area. When the stacking height is high, the lifting and lowering adjustment of the lifting seat 22 is achieved by lifting the reinforcing support plate 21 of the driving part 20 in the lifting groove 211, and then the height adjustment of the multiple lifting panels 12 is achieved, thereby adjusting the top height of the placement area. Even if the height of the material stacking is high, the material will not fall. Specifically, after the height adjustment of the multiple lifting panels 12 is completed, the material can be fixed by the screw rod. The threaded connection between 23 and the first threaded hole 221 is used to fix the lifting seat 22 to prevent it from sliding. After the bagged filling material is stacked, the baffle 11 is slidably installed by cooperating with the provided installation groove 301 and the limiting protrusion 111 until the baffle 11 abuts against the limiting block 302, and then the baffle 11 is fixedly installed by the threaded connection between the bolt member 61 and the second threaded hole 112, so that the baffle 11 can further limit the stacked filling material, and even if it passes through a bumpy road during transportation, the stacked filling material can be prevented from falling during transportation.
