Description

Technical Field

[0001] The invention relates to the technical field of construction transportation, and in particular to a material transportation device for building construction. Background Art

[0002] When constructing in an area with a steep slope, it is very difficult to transport construction materials from the bottom of the slope to the top of the slope in the case of inconvenient traffic. The prior art mostly uses cable dragging to transport materials to the construction area. For example, in the prior art, a patent document with announcement number CN108564320B discloses a material transportation device. Specifically, it is a mountain construction material transportation device for solving the difficulty of material transportation during construction on a mountainous area, comprising two sets of loading and transportation mechanisms, a pull rope and a pulley mechanism; the loading and transportation mechanism further comprises a loading roller, a bracket and a loading basket; the roller is connected to the bracket, and the roller can rotate relative to the bracket; the front end of the loading basket is located above the loading roller; the pulley mechanism further comprises a pulley and a vertical pole; the vertical pole is fixed on the ground, the pulley is sleeved on the top of the vertical pole, the rope body of the pull rope is wrapped around the groove of the pulley at least once, and the connecting rods in the two sets of the loading and transportation mechanisms are respectively fixedly connected to the two ends of the pull rope. Due to the above design, the invention can conveniently and quickly transport materials from the foot of the mountain to the construction site, and the installation is quick and the cost is low.

[0003] In actual use, the above scheme requires that the slope surface meets the conditions for the loading basket to pass through, otherwise the slope surface needs to be corrected and leveled. Rebuilding the slope surface is very difficult, time-consuming, and costly. After all, many times the slope surface does not meet the construction conditions. Based on this, the existing transportation device has difficulties in transporting materials, high basic construction costs, and low work efficiency when the slope surface cannot meet the conditions for the loading frame to pass through. It is not convenient to use and needs to be solved urgently. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art that when the slope surface cannot accommodate the passing of the loading frame, the existing transportation device has difficulty in transporting materials, high foundation construction costs, low work efficiency, and is not convenient to use, and to propose a material transportation device for construction.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a material transportation device for construction, including a winch, a cable and a pile frame, the bottom end of the pile frame is rotatably connected to a base on the foundation, a hanging basket is arranged at the top of the pile frame, and clamps are movably installed on both sides of the pile frame, and a fixed constraint is formed between the cable and the pile frame through the clamps.

[0006] The first hoist and the second hoist are respectively fixedly installed at the construction site, the cable passes through the pile frame and the two clamps, one end of the cable is reeled in the first hoist, and the other end of the cable is reeled in the second hoist.

[0008] Among them, the inner cavity of the outer sleeve is a conical cavity, and the two clamping blocks cooperate to form a conical column structure. The two clamping blocks are slidably inserted in the conical cavity of the outer sleeve, and a T-slot is provided on the surface of the transmission plate. T-slide blocks are fixedly installed at the ends of the two clamping blocks, and the T-slide blocks are slidably installed in the T-slot. Semicircular holes are provided on the opposite surfaces of the two clamping blocks. The cable passes through the clamping device through the semicircular holes on the two clamping blocks. The first hydraulic cylinder telescopes to drive the clamping blocks to move, and the clamping blocks clamp the surface of the cable, so that a fixed constraint is formed between the cable and the pile frame, and the constraint can be released by manual control.

[0009] Preferably, a telescopic frame is slidably installed inside the pile frame, a cantilever rod is fixedly installed on the top of the telescopic frame, the hanging basket is rotatably suspended on the surface of the cantilever rod, and a second hydraulic cylinder is fixedly installed on the front and rear side surfaces of the pile frame, and a plurality of positioning grooves are provided on the front and rear side surfaces of the telescopic frame. The telescopic end of the second hydraulic cylinder is extended and inserted into the positioning groove to realize the fixed constraint between the telescopic frame and the pile frame, so as to facilitate the pile frame to be flipped by pulling the cable. After the telescopic end of the second hydraulic cylinder is contracted, the fixed constraint between the telescopic frame and the pile frame can be released.

[0010] A plurality of stepped guide wheels are rotatably mounted on both the left and right sides of the pile frame. The guide wheels roll along the surface of the telescopic frame to reduce the resistance of the telescopic frame when performing telescopic movements.

[0011] Preferably, a first roller is rotatably installed at the bottom end of the telescopic frame, and the cable located in the pile frame passes around the surface of the first roller. An anti-slip roller is rotatably installed at the bottom end of the telescopic frame, and the anti-slip roller is arranged parallel to the first roller.

[0014] The present invention has the following beneficial effects:

[0015] 1. The transport device proposed in the present invention transports building materials back and forth between low and high places by pulling the pile frame with cables to swing, and can easily cross inconvenient ground, saving a lot of time and cost for slope foundation construction. The design structure is simple, which is convenient for moving and installing equipment when the construction site is transferred, and has the advantages of large load capacity and high transportation efficiency.

[0016] Compared with the sliding transport equipment that suspends materials through suspension cables, this transport device has a larger transport load, such as transporting some heavier concrete prefabricated parts, construction equipment, etc., and can cross higher obstacles;

[0017] Compared with tower cranes, tower cranes are troublesome to disassemble and assemble, and are not convenient to disassemble and assemble and transfer as the construction site changes. The horizontal transportation distance of the tower crane is limited to the operating radius. The greater the horizontal transportation distance, the greater the danger. The transportation device proposed in the present invention has a large horizontal transportation distance and is more stable and safe, and can better meet the use requirements of material transportation on slope construction sites.

[0018] 2. The transport device proposed by the present invention arranges a telescopic frame in the pile frame, and the hanging basket is installed on the top of the telescopic frame. The traction of the cable can not only control the flipping angle of the pile frame, but also control the telescopic length of the telescopic frame, thereby simplifying the structure of the transport device and providing convenience for operation. Through the telescopic adjustment of the telescopic frame, the transport distance is expanded, and the hanging basket can reach different construction areas. When the telescopic frame is retracted into the pile frame, the height of the pile frame is reduced when it is in a vertical state, thereby increasing the stability of the transport device during the flipping process.

[0019] 3. The transport device proposed by the present invention provides clamps on both sides of the pile frame, and uses the clamps to limit the extension direction and length of the cable, which provides convenience for controlling the flipping of the pile frame and the telescopic movement of the telescopic frame through the cable. The clamps on both sides insure each other, which greatly improves the safety of the cable pulling pile frame. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Reference Figure 1-9 A material transportation device for construction includes a winch, a cable 1 and a pile frame 2. A concrete foundation is built in the construction area. A base 22 is fixedly installed on the built foundation. The bottom end of the pile frame 2 is rotatably connected to the base 22 on the foundation. A hanging basket 3 is provided at the top of the pile frame 2. Clamps are movably installed on both sides of the pile frame 2.

[0033] The first hoist 4 and the second hoist 5 are fixedly installed at the construction site. The cable 1 passes through the pile frame 2 and two clamps. One end of the cable 1 is reeled in the first hoist 4, and the other end of the cable 1 is reeled in the second hoist 5.

[0034] Specifically, Figure 5 , Figure 6As shown, the clamping device includes an outer sleeve 6 and two clamping blocks 7. A first hydraulic cylinder 8 is fixedly installed on the surface of the outer sleeve 6. A transmission plate 9 is fixedly installed on the telescopic end of the first hydraulic cylinder 8. The ends of the two clamping blocks 7 are slidingly connected to the transmission plate 9. A connecting plate 10 is rotatably installed on the side of the pile frame 2, and the outer sleeve 6 is rotatably connected to the connecting plate 10.

[0035] Among them, the inner cavity of the outer sleeve 6 is a conical cavity, and the two clamping blocks 7 cooperate to form a conical column structure. The two clamping blocks 7 are slidably inserted in the conical cavity of the outer sleeve 6. The surface of the transmission plate 9 is provided with a T-shaped slot 11. The ends of the two clamping blocks 7 are fixedly installed with a T-shaped slider 12. The T-shaped slider 12 is slidably installed in the T-shaped slot 11. The opposite surfaces of the two clamping blocks 7 are provided with semicircular holes. The cable 1 passes through the clamping device through the semicircular holes on the two clamping blocks 7. See Figure 5 .

[0036] During use, the first hydraulic cylinder 8 contracts, providing a pressure for the clamping block 7, so that the clamping block 7 is pressed into the outer sleeve 6, and the upper and lower clamping blocks 7 hold the surface of the cable 1, so that a fixed constraint is formed between the cable 1 and the pile frame 2. Conversely, the first hydraulic cylinder 8 extends, driving the clamping block 7 to separate a certain distance in the outer sleeve 6, thereby releasing the constraint force of the clamping block 7 holding the cable 1.

[0037] In this embodiment, reference Figure 4 A telescopic frame 13 is slidably installed inside the pile frame 2, a cantilever rod 14 is fixedly installed on the top of the telescopic frame 13, and the hanging basket 3 is rotatably suspended on the surface of the cantilever rod 14. The front and rear side surfaces of the pile frame 2 are fixedly installed with a second hydraulic cylinder 15, and the front and rear side surfaces of the telescopic frame 13 are provided with a plurality of positioning grooves 16. The telescopic end of the second hydraulic cylinder 15 extends out and can be inserted into the positioning groove 16 to realize the fixed constraint between the telescopic frame 13 and the pile frame 2.

[0038] A plurality of stepped guide wheels 19 are rotatably mounted on both the left and right sides of the pile frame 2. The guide wheels 19 roll along the surface of the telescopic frame 13 to reduce the resistance of the telescopic frame 13 to the telescopic action.

[0039] A first roller 17 is rotatably mounted on the bottom end of the telescopic frame 13. The cable 1 located in the pile frame 2 passes over the surface of the first roller 17. An anti-slip roller 20 is rotatably mounted on the bottom end of the telescopic frame 13. The anti-slip roller 20 is arranged parallel to the first roller 17. The cable 1 passes through the gap between the anti-slip roller 20 and the first roller 17.

[0040] Installation windows are provided on both sides of the pile frame 2, and two second rollers 18 are rotatably installed in the installation windows on both sides. The cable 1 extends from the gap between the two second rollers 18 to the outside of the pile frame 2 and then passes through the clamp.

[0041] It should be emphasized that, according to the weight of the transported material, multiple cables 1 can be provided to pull the pile frame 2 to move. For the sake of convenience, this embodiment takes one cable 1 as an example.

[0042] How to use: Figure 2 As shown in the dotted line position, the material is transferred to the hanging basket 3 at a low position. At this time, the telescopic end of the second hydraulic cylinder 15 extends and inserts into the positioning groove 16 to restrict the movement of the telescopic frame 13. Then, the first winch 4 reels the cable 1, and the second winch 5 slowly releases the cable 1. The cable 1 pulls the pile frame 2 to rotate counterclockwise, so that the hanging basket 3 is transported to the high construction area (such as Figure 8 shown);

[0043] See Figure 8 , the telescopic end of the second hydraulic cylinder 15 is shortened and moved out of the positioning groove 16, the clamp at B keeps clamping the cable 1, and the clamp at A releases the clamping of the cable 1. At this time, the first hoist 4 reels the cable 1, and the telescopic frame 13 extends upward until the basket 3 reaches a predetermined height. The first hoist 4 stops, the clamp at A clamps the cable 1, and the telescopic end of the second hydraulic cylinder 15 extends and inserts into the positioning groove 16 to complete the transportation of materials;

[0044] See Fig. 9 , the telescopic end of the second hydraulic cylinder 15 is shortened again and moved out of the positioning groove 16, the clamp at B keeps clamping the cable 1, and the clamp at A is released from the cable 1. At this time, the first hoist 4 releases the cable 1, and the telescopic frame 13 slides downward and retracts into the pile frame 2 under the action of its own weight. The first hoist 4 stops, the clamp at A clamps the cable 1, and the telescopic end of the second hydraulic cylinder 15 extends out and inserts into the positioning groove 16;

[0045] Finally, the second winch 5 reels the cable 1, and the first winch 4 slowly releases the cable 1, and the cable 1 pulls the pile frame 2 to rotate clockwise, so that the hanging basket 3 is transported to the lower construction area (such as Figure 2 The dashed line part).

[0046] By arranging a telescopic frame 13 in the pile frame 2 and installing the hanging basket 3 on the top of the telescopic frame 13, the traction of the cable 1 can not only control the flipping angle of the pile frame 2, but also control the telescopic length of the telescopic frame 13, thereby simplifying the structure of the transportation device and providing convenience for operation. Through the telescopic adjustment of the telescopic frame 13, the transportation distance is expanded, so that the hanging basket 3 can reach different construction areas. When the telescopic frame 13 is retracted into the pile frame 2, so that the pile frame 2 is in a vertical state, the height of the hanging basket 3 is reduced, thereby increasing the stability of the flipping process of the transportation device.

[0047] During the transportation of materials, Figure 5As shown, when the right-side clamp fails, the left-side clamp is in the state of clamping the cable 1. In the process of the cable 1 pulling the pile frame 2 to the right, the cable 1 provides a force (friction force) to the clamp block 7 in the left-side clamp, which will cause the clamp block 7 to be pressed into the outer sleeve 6 (specifically the left-side clamp), that is, the left-side clamp will become tighter and tighter (the same is true in reverse, which will not be repeated here). By movably arranging clamps on both sides of the pile frame 2, the clamps on both sides insure each other, which greatly improves the safety of the cable 1 pulling the pile frame 2. The clamp is used to limit the extension direction and length of the cable 1, which provides convenience for controlling the flipping of the pile frame 2 and the telescopic movement of the telescopic frame 13 through the cable 1.

[0048] In this embodiment, a rotating shaft 21 is fixedly installed at both ends of the pile frame 2, and the bottom end of the pile frame 2 is rotatably connected to the base 22 via the rotating shaft 21. Figure 2 During the first installation, the hanging basket 3 is removed, the top of the pile frame 2 is facing the ground, and a raised base 22 is set on the ground. The top of the pile frame 2 is rotatably connected to the base 22 on the ground through the rotating shaft 21. The pile frame 2 is turned over by the traction of the cable 1, so that the rotating shaft 21 at the bottom of the pile frame 2 is docked with the high base 22, and then they are rotated and assembled together, and then the subsequent components are assembled. The installation of the transport device on the high slope is completed by this method. Multiple transport devices are installed on the slope to realize long-distance material transportation relay.

[0049] Compared with the sliding transport equipment for suspending materials through suspension cables, this transport device has a larger transport load, such as transporting some heavier concrete prefabricated parts, construction equipment, etc., because the weight of the materials acts on the pile frame 2 and the telescopic frame 13, and can cross higher obstacles (here refers to obstacles at the protrusions of the slope itself, without the need to re-correct the slope that is inconvenient to pass);

[0050] Compared with tower cranes, tower cranes are troublesome to assemble and disassemble, and it is not convenient to assemble and disassemble and transfer them as the construction site changes. The horizontal transportation distance of the tower crane is limited to the operating radius. When transporting heavier materials, the greater the horizontal transportation distance, the easier it is for the tower body to become unstable and the greater the danger. The transportation device proposed in the present invention has a large horizontal transportation distance and is more stable and safe, and can better meet the use requirements of material transportation on slope construction sites.

[0051] The transport device proposed in the present invention transports construction materials back and forth between low and high places by pulling the pile frame 2 to swing through the cable 1, and can easily cross inaccessible ground, saving a lot of time and cost for slope foundation construction. The design structure is simple, which is convenient for moving and installing equipment when the construction site is transferred, and has the advantages of large load capacity and high transportation efficiency.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
