Description

Technical Field

[0001] The utility model belongs to the technical field of tracks, and in particular relates to a liftable track device and a conveying track. Background Art

[0002] A waterproof gate is a gate designed to prevent flooding caused by sudden water inrush during mining. It consists of concrete wall buttresses, door frames and openable door panels, and the gate is usually open. To ensure that the waterproof gate is closed normally, the track within the rotation range of the waterproof gate panel needs to be set as a short movable track. Because the track surface height of the movable track is higher than the lowest point of the door panel, the waterproof gate cannot be closed. Therefore, when water seepage occurs, it must be disassembled to avoid the gate and close the gate.

[0003] The movable track in the related art avoids the door panel by disassembling so that the door panel can be opened or closed normally. However, the disassembly and installation of the movable track are complicated. Summary of the invention

When it is necessary to avoid the door panel, the height of the second end of the track assembly is lowered by lowering the execution end of the lifting drive assembly. After the height of the second end of the track assembly is lowered, it will not interfere with the opening and closing of the door panel, making it easy to avoid the movable track, without the need to disassemble the movable track, and easy to operate. In addition, the method of lowering the track height for avoidance is not affected by the cross-sectional height of the chamber, and can be applied in different chambers, so that mass production can be carried out.

[0009] In this embodiment, two second connecting lugs are provided, the two second connecting lugs are arranged in parallel and spaced apart, and the first connecting lug is located between the two second connecting lugs.

[0010] In this embodiment, the lifting drive assembly includes: a rotating support member, which is arranged between the track assembly and the mounting base, and the rotating support member has a hinged end and a free end, and the hinged end of the rotating support member is hinged to the mounting base through a second hinge shaft.

[0011] In this embodiment, the free end of the rotating support member is provided with an arcuate surface on the side facing the track assembly, and the hinged end of the rotating support member is provided with an arcuate surface on the side facing the mounting base, so that when the rotating support member rotates around the second hinge axis, the hinged end is rollingly connected to the mounting base and the free end is rollingly connected to the track assembly.

[0012] In this embodiment, the lifting drive assembly further includes an auxiliary lifting handle, and the auxiliary lifting handle is disposed on the rotating support member.

[0013] In this embodiment, the lifting drive assembly also includes a connecting seat, which is arranged on the mounting base, and the connecting seat is U-shaped. The hinged end of the rotating support member is located between the side walls at both ends of the connecting seat. A third connecting hole is provided on the rotating support member, and a fourth connecting hole is provided on the connecting seat. The second hinge shaft passes through the third connecting hole and the fourth connecting hole.

[0014] In this embodiment, the track assembly includes: a track body; and a reinforcement seat, wherein the reinforcement seat is disposed at the bottom of the track body.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0034] In this embodiment, if Figures 1 to 3 As shown, the liftable track device includes a mounting base 1, a track assembly 2 and a lifting drive assembly 3, the track assembly 2 is arranged above the mounting base 1, and in the conveying direction of the track assembly 2, the track assembly 2 has a first end 21 and a second end 22, and the first end 21 is hinged to the mounting base 1; the lifting drive assembly 3 is arranged on the mounting base 1, and the lifting drive assembly 3 is arranged opposite to the second end 22, and the lifting drive assembly 3 is used to lift the second end 22 of the track assembly 2.

[0035] Specifically, in the conveying direction of the track assembly 2 , the lengths of the mounting base 1 and the conveying track match, and the mounting base 1 forms a stable support for the track assembly 2 .

[0036] It should be noted that if Figures 1 to 3As shown, the two ends of the track assembly 2 in the conveying direction are suitable for setting the first track 10 and the second track 20 respectively, and the door panel 100 is located between the first track 10 and the conveying track. The height of the first track 10 is higher than the height of the second track 20, and the first end 21 of the track assembly 2 matches the height of the second track 20. When the second end 22 of the track assembly 2 is not raised, the height of the second end 22 of the track assembly 2 is lower than the height of the first track 10. When the second end 22 of the track assembly 2 is raised, the height of the second end 22 of the track assembly 2 can match the height of the first track 10, and the first end 21 of the track assembly 2 matches the height of the second track 20, so that the conveying can be continuous.

[0037] It can be understood that when the liftable track device in this embodiment is needed for transportation, the second end 22 of the track assembly 2 is lifted by the lifting drive assembly 3. When the second end 22 of the track assembly 2 is lifted, the track assembly 2 rotates around the hinge between the first end 21 and the mounting base 1 until the second end 22 is lifted to a preset position, so that the track conveying surface of the track assembly 2 is in an inclined state with a lower height of the first end 21 and a higher height of the second end 22, so that the track assembly 2 and the two adjacent sections of the track are docked. When the door panel 100 needs to be avoided, the height of the second end 22 of the track assembly 2 is reduced by lowering the execution end of the lifting drive assembly 3. After the height of the second end 22 of the track assembly 2 is reduced, it will not interfere with the opening and closing of the door panel 100, making it easy to avoid the movable track, without the need to disassemble the movable track, and easy to operate. In addition, the method of lowering the track height for avoidance is not affected by the cross-sectional height of the chamber, and can be applied in different chambers, so that mass production can be carried out.

[0038] In this embodiment, if Figure 1 and Figures 4 to 7 As shown, the liftable track device further includes a first connecting lug 4, a second connecting lug 5 and a first hinge shaft 6. The first connecting lug 4 is disposed at the first end 21 of the track assembly 2, and a first connecting hole is disposed on the first connecting lug 4. The second connecting lug 5 is disposed on the mounting base 1 and is opposite to the first connecting lug 4, and a second connecting hole is disposed on the second connecting lug 5. The first hinge shaft 6 passes through the first connecting hole and the second connecting hole.

[0039] For example, the first connecting lug 4 and the track assembly 2 can be welded or integrally formed. The first connecting lug 4 and the track assembly 2 are connected by welding, which can make it easier to connect the first connecting lug 4 and the track assembly 2. The first connecting lug 4 and the track assembly 2 are connected by integrally forming, which is conducive to improving the connection strength and high processing efficiency.

[0040] It can be understood that by providing a first connecting lug 4 on the rail assembly 2 and a second connecting lug 5 on the mounting base 1, the rail assembly 2 and the mounting base 1 are hinged by a first hinge shaft 6 passing through the first connecting lug 4 and the second connecting lug 5, which can make the connection between the rail assembly 2 and the mounting base 1 more convenient.

[0041] In this embodiment, if Figure 3 and Figure 5 As shown, two second connecting lugs 5 are provided, the two second connecting lugs 5 are arranged in parallel and spaced apart, and the first connecting lug 4 is located between the two second connecting lugs 5 .

[0042] It can be understood that by setting two second connecting lugs 5, the first connecting lug 4 is located between the two second connecting lugs 5, and the first connecting lug 4 can be limited by the two second connecting lugs 5, which is beneficial to making the track assembly 2 structure more stable, thereby making the track assembly 2 transport more stable.

[0043] In this embodiment, if Figures 1 to 3 As shown, the lifting drive assembly 3 includes a rotating support 31, which is arranged between the track assembly 2 and the mounting base 1. The rotating support 31 has a hinged end and a free end. The hinged end of the rotating support 31 is hinged to the mounting base 1 through a second hinge shaft 7.

[0044] Specifically, the rotating support 31 has a first position that makes the track assembly 2 in a horizontal state, and a second position that makes the track assembly 2 in an inclined state. When the rotating support 31 is in the first position, the hinged end of the rotating support 31 is adjacent to the first end 21 of the conveying assembly, and the free end of the rotating support 31 is away from the first end 21 of the conveying assembly. When the rotating support is in the second position, the free end and the hinged end of the rotating support 31 are distributed vertically.

[0045] When using the rotating support 31 in this embodiment, the operator lifts the free end of the rotating support 31, and the rotating support 31 rotates around the second hinge shaft 7. When the rotating support 31 rotates to a vertical state, the free end of the rotating support 31 lifts the second end 22 of the conveying track to a preset position.

[0046] In this embodiment, if Figure 2 and Figure 8 As shown, the free end of the rotating support member 31 is provided with an arc surface 311 on the side facing the track assembly 2, and the hinged end of the rotating support member 31 is provided with an arc surface 311 on the side facing the mounting base 1, so that when the rotating support member 31 rotates around the second hinge axis 7, the hinged end is rollingly connected with the mounting base 1 and the free end is rollingly connected with the track assembly 2.

[0047] It can be understood that the lifting of the second end 22 of the track assembly 2 is achieved by rotating the free end of the rotating support member 31 upward to support the second end 22 of the track assembly 2. When the rotating support member 31 rotates, the parts that abut against the track assembly 2 and the mounting base 1 are all arc-shaped surfaces 311, so that when the rotating support member 31 rotates, it is respectively connected with the track assembly 2 and the mounting base 1 in a rolling manner, which can make the rotating support member 31 rotate more smoothly and more labor-saving.

[0048] In this embodiment, if Fig. 9 As shown, the lifting drive assembly 3 also includes an auxiliary lifting handle 32 , and the auxiliary lifting handle 32 is arranged on the rotating support 31 .

[0049] For example, auxiliary lifting handles 32 are provided on both sides of the rotating support 31, so that there are force application points on both sides of the rotating support 31, which makes the operation more convenient.

[0050] When the rotating support member 31 needs to be rotated, the operator drives the rotating support member 31 to rotate by lifting the auxiliary lifting handles 32 on both sides of the rotating support member 31 , and uses the auxiliary lifting handles 32 as force application points to make the operation more convenient.

[0051] In this embodiment, if Figure 1 and Figure 4 , Figure 5 As shown, the lifting drive assembly 3 also includes a connecting seat 33, which is arranged on the mounting base 1, and the connecting seat 33 is U-shaped. The hinged end of the rotating support member 31 is located between the side walls at both ends of the connecting seat 33, and a third connecting hole is provided on the rotating support member 31, and a fourth connecting hole is provided on the connecting seat 33, and the second hinge shaft 7 passes through the third connecting hole and the fourth connecting hole.

[0052] For example, the connection seat 33 and the mounting base 1 can be welded or integrally formed. The connection seat 33 and the mounting base 1 are connected by welding, which can make the connection between the connection seat 33 and the mounting base 1 more convenient. The connection seat 33 and the mounting base 1 are connected by integrally forming, which is conducive to improving the connection strength and high processing efficiency.

[0053] It can be understood that by setting up the connecting seat 33, the track assembly 2 and the mounting base 1 can be easily connected. The connecting seat 33 is U-shaped, and the hinged end of the rotating support member 31 is set between the two side walls of the connecting seat 33. The rotating support member 31 is limited by the connecting seat 33, which is conducive to the stable rotation of the rotating support member 31 and the stable support of the track assembly 2.

[0054] In this embodiment, if Figure 1 and Figure 7 As shown, the track assembly 2 includes a track body 23 and a reinforcement seat 24 , and the reinforcement seat 24 is disposed at the bottom of the track body 23 .

[0055] Specifically, the track body 23 has a track surface for conveying, which is used to realize conveying. The structure of the track body 23 is conventional in the prior art and will not be described in detail here.

[0056] In this embodiment, by disposing a reinforcing seat 24 below the track body 23 , the strength of the track can be enhanced and the deformation of the track body 23 can be reduced.

[0057] In this embodiment, if Figure 7 As shown, the reinforcement seat 24 is an H-shaped steel.

[0058] Specifically, the H-shaped steel includes two parallel flanges and a web connecting the two flanges. The two flanges of the reinforcing seat 24 are distributed up and down, that is, one of the two flanges is connected to the track body 23, and the other is adjacent to the mounting base 1.

[0059] It is understandable that setting the reinforcement seat 24 as an H-shaped steel can make the reinforcement seat 24 have better bending and torsional resistance and a better strength-to-weight ratio. Under the same load-bearing capacity, the H-shaped steel is lighter and more economical.

[0060] This embodiment also provides a conveying track, such as Figures 1 to 3 As shown, the conveying track includes a first track 10, the above-mentioned liftable track device and a second track 20 which are arranged in sequence. The height of the first track 10 is higher than the height of the second track 20. When the track assembly 2 is in a raised state, the first end 21 of the track assembly 2 is equal to the height of the second track 20, and the second end 22 of the track assembly 2 is equal to the height of the first track 10.

[0061] When installing the liftable track device, a sunken groove 30 is constructed on the bottom surface between the first track 10 and the second track 20, and the mounting base 1 is set at the bottom of the groove 30, and the height of the track component 2 when not lifted is equal to the height of the second track 20, so that the track component 2 forms a height difference with the first track 10, and the door panel 100 is located between the first track 10 and the track component 2.

[0062] It should be noted that when the second end 22 of the track assembly 2 is not lifted, the height of the second end 22 of the track assembly 2 is lower than the height of the first track 10, so that the second end 22 of the track assembly 2 can avoid the door panel 100. When the second end 22 of the track assembly 2 is lifted, the height of the second end 22 of the track assembly 2 can match the height of the first track 10, and the first end 21 of the track assembly 2 matches the height of the second track 20, so that the transportation can be continuous.
