Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering construction machinery, and in particular to an integrated synchronous telescopic device. Background Art

[0002] During lining construction in dams, reservoirs, and other locations, the actual slope length of the dam or reservoir is a variable value. To enable mechanized construction of slopes of varying lengths using the same equipment, it is necessary to enable the concrete conveyor belt to automatically extend and retract as the slope length changes, thereby meeting the diverse needs of the construction site. Existing telescopic devices often utilize telescopic cylinders, wire ropes, drive belts, transmission chains, or rack and pinion gears to achieve this. A certain length must be reserved at the rear for installing a telescopic guide device, or space must be left on the side for installing a power transmission device. This results in an excessively large overall device size and cumbersome installation or transportation processes. Current belt conveyors have limited adjustment capabilities for the belt transport length, allowing only small adjustments. Each adjustment requires reassembly or wire rope tensioning, which is complex, labor-intensive, and unsuitable for concrete lining operations on slopes where the slope length constantly changes. Existing telescopic structures also require an additional drive device, and the telescopic mechanism is difficult to adjust, making it impossible to adaptively adjust the telescopic length. Summary of the Invention

The specific technical solution is as follows: The present invention provides an integrated synchronous telescopic device, comprising a telescopic box beam, an upper belt conveyor and a lower belt conveyor; the telescopic box beam comprises an inner box beam, an outer box beam, an inner moving component and an outer moving component; the inner moving component is installed on the outer side surface of the inner box beam, the outer moving component is installed on the inner side surface of the outer box beam, and the outer box beam is sleeved and slid on the outside of the inner box beam; the lower belt conveyor is installed above the inner box beam, and an inner drop hopper for conveying materials is installed on the lower belt conveyor; the upper belt conveyor is installed above the outer box beam, and an outer drop hopper for conveying materials is installed on the side of the upper belt conveyor, and a staggered overlapping hopper for conveying materials is installed at the end of the upper belt conveyor, and the discharge port of the staggered overlapping hopper is directly opposite to the lower belt conveyor.

[0004] A further improvement of the integrated synchronous telescopic device of the present invention is that the cross section of the outer box beam is inverted U-shaped, and the outer box beam covers are arranged on both sides and above the inner box beam.

[0005] A further improvement of the integrated synchronous telescopic device of the present invention is that the inner moving component includes an inner walking beam and an inner walking wheel group, the inner walking beam is fixed on the outer side of the inner box beam, and the inner walking wheel group is slidably installed on the inner walking beam and connected to the inner side surface of the outer box beam.

[0006] A further improvement of the integrated synchronous telescopic device of the present invention is that a silo is provided on the first side of the inner box beam and the outer box beam, the discharge ports of the outer hopper and the inner hopper are both directly opposite to the silo, and a vibrating rod is provided in the silo.

[0007] A further improvement of the integrated synchronous telescopic device of the present invention is that a seam setting machine is provided on the second side of both the inner box beam and the outer box beam.

[0008] A further improvement of the integrated synchronous telescopic device of the present invention is that an upper driving member is provided on the side of the upper belt conveyor, and a driving rope is connected between the upper driving member and the outer drop hopper.

[0009] A further improvement of the integrated synchronous telescopic device of the present invention is that a receiving hopper is provided at one end of the upper belt conveyor away from the staggered overlapping hopper, and the discharge port of the receiving hopper corresponds to the belt of the upper belt conveyor.

[0010] A further improvement of the integrated synchronous telescopic device of the present invention is that the inner movable component and the outer movable component are arranged in a vertically staggered manner.

It can adapt to the length-varying slope concrete lining operations. It is simple to operate and solves the technical problem that the telescopic devices in the prior art cannot meet the requirements of adaptive adjustment of the length of the telescopic device. The present invention can realize smooth discharge of concrete through the upper and lower belt conveyors, and can realize the leveling and automatic block division of concrete in conjunction with the hopper and the seam setting machine. It is more suitable for slope concrete lining operations with constantly changing slope lengths, can significantly improve construction efficiency, and reduce the types of other slope construction equipment.

[0015] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0016] See also Figures 1 to 5 As shown, an integrated synchronous telescopic device includes a telescopic box girder 2, an upper belt conveyor 3 and a lower belt conveyor 5; the telescopic box girder 2 includes an inner box girder 7, an outer box girder 10, an inner moving component and an outer moving component; the inner moving component is installed on the outer side surface of the inner box girder 7, the outer moving component is installed on the inner side surface of the outer box girder 10, and the outer box girder 10 is sleeved and slides on the outside of the inner box girder 7; the lower belt conveyor 5 is installed above the inner box girder 7, and an inner drop hopper 15 for conveying materials is installed on the lower belt conveyor 5; the upper belt conveyor 3 is installed above the outer box girder 10, and an outer drop hopper 11 for conveying materials is installed on the side of the upper belt conveyor 3, and a staggered overlapping hopper 8 for conveying materials is installed at the end of the upper belt conveyor 3, and the discharge port of the staggered overlapping hopper 8 is directly opposite to the lower belt conveyor 5.

[0017] Specifically, an upper mounting seat 9 for installing the upper belt conveyor 3 is provided on the outer box beam 10, and a lower mounting seat 6 for installing the lower belt conveyor 5 is provided on the inner box beam 7. The upper belt conveyor 3 is used to transport concrete transported by a concrete transport truck or other transport equipment, and smoothly transport the concrete to the required location and the staggered overlapping hopper 8. The lower belt conveyor 5 is used to transport the concrete delivered by the upper belt conveyor 3 through the staggered overlapping hopper 8, and transport it to the required location. Both ends of the telescopic box beam 2 are connected with a support device for walking on the upper and lower planes of the slope, and the end of the inner box beam 7 away from the outer box beam 10 is provided with a tail frame 16 for connecting the support device and the inner box beam 7. The present invention can realize the non-powered support sliding extension and retraction of the telescopic box beam, and the built-in silo design can move synchronously with the telescopic box beam; the offset of the two belt conveyors is achieved through the overlapping hopper at the tail of the upper belt conveyor, such as Figure 5 As shown, it can ensure that the concrete transported from the upper belt conveyor to the lower belt conveyor falls smoothly, and ensure that the outer box beam 10 does not increase the width while accommodating the inner box beam 7, and ensure that the overall volume of the device is not too large, thereby reducing manufacturing and transportation costs.

[0018] Preferably, the cross section of the outer box beam 10 is inverted U-shaped, and the outer box beam 10 is covered on both sides and above the inner box beam 7. Specifically, there is a certain distance between the top surface of the inner box beam 7 and the inner top wall of the outer box beam 10, which can meet the requirement that the lower belt conveyor 5 extends into the interior of the outer box beam 10 during expansion and contraction.

[0019] Preferably, Figure 3 and Figure 4 As shown in FIG. 1 , the interior mobile assembly comprises an interior walking beam 17 and an interior wheel group 18, wherein the interior walking beam 17 is fixed on the outer side of the interior box beam 7, and the interior wheel group 18 is slidably mounted on the interior walking beam 17 and is connected on the inner side of the outer box beam 10. The interior wheel group 18 can slide adaptively on the interior walking beam 17 according to the width of the inclined plane, thereby requiring no other power sources to satisfy the telescopic function of the telescopic box beam 2. Concretely, the structure of the outer mobile assembly is identical with that of the interior mobile assembly, but the mounting position is opposite. The outer mobile assembly comprises an outer walking beam 19 and an outer wheel group 20, wherein the outer walking beam 19 is fixed on the inner side of the outer box beam 10, and the outer wheel group 20 is slidably mounted on the outer walking beam 19 and is connected on the outer side of the interior box beam 7. In addition, the structure in which the interior mobile assembly slides with the outer mobile assembly can also be replaced by a wheel axle sliding, or can be that the sliding block chute cooperates to slide.

[0020] Preferably, Figure 2As shown, the first sides of both the inner box girder 7 and the outer box girder 10 are provided with silos. The discharge ports of the outer hopper 11 and the inner hopper 15 are both aligned with the silos. Vibrators 4 are located within the silos. The silos are used to store concrete dropped from the outer hopper 11 or the inner hopper 15 and evenly spread it. Specifically, the silos include an inner silo 14 fixed to the first side of the inner box girder 7 and an outer silo 13 fixed to the first side of the outer box girder 10. Multiple vibrators 4 are spaced apart within the inner silo 14 and the outer silo 13. The high-frequency vibration (150-200 Hz) of the vibrators 4 evenly spreads the concrete dropped from the silos into the inner silo 14 and the outer silo 13, removing air bubbles within the concrete for a more compact and smoother surface.

[0021] Preferably, Figure 1 As shown, the second sides of both the inner box girder 7 and the outer box girder 10 are equipped with a seam setting machine 1. The seam setting machine 1 can cut and divide the concrete laid by the inner hopper 14 and the outer hopper 13 to prevent damage to the concrete due to thermal expansion and contraction. The present invention only requires the use of an integrated synchronous telescopic device to install a variety of construction machinery on the telescopic box girder 2. In addition to the seam setting machine 1 and vibrating rod 4 in this embodiment, equipment for smoothing and finishing concrete can also be installed as needed, enabling mechanized construction of concrete with variable slopes, which can significantly improve construction efficiency.

[0022] Preferably, an upper driving member 12 is provided on the side of the upper belt conveyor 3, and a driving rope is connected between the upper driving member 12 and the outer drop hopper 11. In this embodiment, the upper driving member 12 is a motor, and the driving rope is a steel wire rope. The motor drives the steel wire rope to pull the outer drop hopper 11 back and forth on the upper belt conveyor 3, thereby controlling the falling position of the concrete. A lower driving member 21 is also provided on the lower belt conveyor 5, and the inner drop hopper 15 is pulled back and forth on the lower belt conveyor 5 by the connected steel wire rope. The outer drop hopper 11 and the inner drop hopper 15 are both installed on the side of the upper belt conveyor 3 of the outer box girder 10 and the lower belt conveyor 5 of the inner box girder 7 through a slide trolley. In addition, the structure in which the motor and the steel wire rope drive the movement of the outer drop hopper 11 and the inner drop hopper 15 can also be replaced with a rack and pinion drive, a screw drive, a pulley drive, etc.

[0023] Preferably, a receiving hopper is provided at one end of the upper belt conveyor 3 away from the staggered overlapping hopper 8, and the discharge port of the receiving hopper corresponds to the belt of the upper belt conveyor 3. The receiving hopper is used to receive concrete transported by a concrete transport truck or other transport equipment, and is in the shape of a hopper body with a larger upper portion and a smaller lower portion to facilitate the falling of concrete.

[0024] Preferably, the inner moving assembly and the outer moving assembly are staggered up and down to avoid interference between the inner box beam 7 and the outer box beam 10. The inner moving assembly and the outer moving assembly are two symmetrically arranged groups, which are respectively installed on both sides of the inner box beam 7 and the outer box beam 10.

[0025] The integrated synchronous telescopic device of the present invention is connected to support devices for traveling on the upper and lower planes of the slope at both ends. The telescopic box beam 2 can be extended and retracted by the self-moving inner and outer moving components. No power source is required. It can be adaptively extended and retracted based on the slope of the work site and the movement of the support devices at both ends. It can adapt to the length-varying slope concrete lining operations. It is simple to operate and solves the technical problem that the telescopic devices in the prior art cannot meet the requirements of adaptive adjustment of the length of the telescopic device. The present invention can realize smooth discharge of concrete through the upper belt conveyor 3 and the lower belt conveyor 5, and can realize the leveling and automatic block division of concrete in conjunction with the hopper and the seam setting machine 1. It is more suitable for slope concrete lining operations with constantly changing slope lengths, can significantly improve construction efficiency, and reduce the types of other slope construction equipment.
