Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction, in particular to a mobile and assembleable concrete unloading device. Background Art

[0002] At present, during the construction of urban roads, when pouring concrete in multi-bin structures such as power trenches and integrated pipe corridors, pump trucks are often used to directly pump concrete into the structural walls, and workers then use inserted vibrators to vibrate the concrete to make it flow into the structural bottom plate. During the pouring process, due to unstable pump pipes and improper operation of workers, concrete is easily spilled on the top plate or waste of concrete.

[0003] In addition, if the concrete scattered on the top plate is not handled in time, once the initial setting time of the concrete is exceeded, it is easy to form cold joints between the concrete and the subsequently poured concrete when pouring continues. Later, under the influence of various media such as external water, it will have an adverse effect on the structural steel bars and cause damage to the structure. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a mobile and assembleable concrete unloading device, which can ensure the integrity and continuity of the structural concrete and the tightness of the structure between the middle partition wall and the top plate, thereby achieving the purpose of saving labor and material costs and ensuring a reliable and beautiful structure.

[0009] Furthermore, the four sides of the upper opening of the discharge chute are respectively connected with extension grooves through mortise and tenon structures.

[0010] The detachable installation extension trough cooperates with the discharge trough through mortise and tenon connection. When it is necessary to expand the holding capacity of the discharge trough, the extension trough can be installed. When it is not needed, the extension trough can be removed to save space.

[0011] Furthermore, a bidirectional screw is rotatably installed between the two supporting legs along the vertical guide rail direction, and a guide groove of the vertical guide rail in the length direction is opened in the front and rear of the base plate opposite to the bidirectional screw. Each movable plate is vertically connected with a guide rod located in the guide groove in the front and rear of the unloading chute in the moving direction, and the lower end of each guide rod is vertically threadedly connected to the corresponding bidirectional screw.

[0012] The bidirectional lead screw is rotatably installed between the supporting legs. The bidirectional lead screw is threadedly connected to the guide rod and the guide groove is used to limit the guide rod, so that the bidirectional lead screw can be rotated to drive the two movable plates to move toward or away from each other and adjust the size of the discharge port.

[0013] Furthermore, two bidirectional lead screws are respectively provided with sprockets at one end on the same side, and a double-row sprocket located between the two sprockets is rotatably provided at the bottom of the discharge chute via a rotating shaft, and the double-row sprockets are respectively connected to the two sprockets via chains.

[0015] Furthermore, the rotating shaft passes through the center of the double-row sprocket and is equipped with a hand wheel.

[0016] By setting the hand wheel, the double-row sprocket and the sprocket can be easily driven to rotate through the rotating shaft, thereby controlling the rotation of the two lead screws, driving the opening and closing of the two movable plates, and achieving the purpose of controlling the size of the discharge port.

[0017] Furthermore, a hand-held retractable rod is detachably mounted on the side wall of the discharge chute via nuts and bolts.

[0018] Beneficial effects of the utility model:

[0019] The utility model unloads and transports materials by cooperating with the guide rail and the guide wheel at the bottom of the unloading chute. The unloading device can effectively solve the construction cold joint formed by the concrete between the wall and the top plate due to the concrete exceeding the initial setting time when pouring concrete, and ensure the integrity of the structure. The unloading chute adopts a lightweight and high-strength aluminum alloy mortise and tenon structure to ensure safety and stability during the unloading process, and is also convenient for manual control.

[0020] The use of a bidirectional lead screw to control the movement of the two movable plates and the size of the discharge port on the bottom plate of the discharge chute can effectively control the pouring speed and pouring volume. The use of an assembleable structure is convenient for workers to assemble and disassemble, which is conducive to greatly saving labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0028] A mobile and assembleable concrete unloading device comprises two parallel guide rails 5 and a unloading chute 3 slidably arranged between the two guide rails 5. A clamping groove 8 is provided on the bottom surface of the guide rail 5 and is clamped on the surface steel bar through the clamping groove 8. A guide groove is formed on the surface of the guide rail 5 for accommodating a guide wheel 7. The clamping groove 8 on the bottom surface of the guide rail 5 should be flat and smooth and fit closely with the surface steel bar to ensure that the guide wheel 7 does not deviate or derail during the forward movement. A hand-held telescopic rod 1 is detachably installed on the side wall of the unloading chute 3 through nuts and bolts. A worker can control the entire unloading device to run along the guide rail 5 by holding the telescopic rod 1. A unloading port 9 is provided at the center of the bottom plate of the unloading chute 3. Two movable plates 11 that can move toward or away from each other and adjust the size of the unloading port 9 are slidably arranged on the bottom plate above the unloading port 9. Support legs 4 are firmly welded to the four corners of the bottom plate corresponding to the unloading port 9, and the ends of the support legs 4 are rotatably installed with guide wheels located in the guide groove. The guide wheel 7 is made of solid rubber material, which has high strength, good toughness, is not easy to deform and has high stability.

[0029] The discharge chute 3 is in the shape of an inverted quadrangular pyramid, and is hollow inside and open at the top. In order to facilitate the control of the load capacity of the discharge chute 3, the four sides of the upper open part of the discharge chute 3 are respectively connected with extension grooves through mortise and tenon structures. It can be selected whether to connect the extension groove 2 according to actual use. The four baffles and the bottom plate of the discharge chute 3 are assembled by mortise and tenon structures made of high-strength and lightweight aluminum alloy materials that can be assembled, which is convenient for disassembly and assembly.

[0030] A bidirectional lead screw 6 is rotatably installed between the two supporting legs 4 along the direction of the vertical guide rail 5. A guide groove 12 of the vertical guide rail in the length direction is opened in the front and rear of the bottom plate opposite to the bidirectional lead screw 6. Each movable plate 11 is vertically connected with a guide rod 10 located in the guide groove 12 in the front and rear of the moving direction of the unloading chute 3. The lower end of each guide rod 10 is vertically threadedly connected to the corresponding bidirectional lead screw 6.

[0031] The two bidirectional lead screws 6 are respectively provided with sprockets 13 at one end on the same side, and a double-row sprocket 15 located between the two sprockets 13 is rotatably provided at the bottom of the discharge chute 3 via a rotating shaft 16, and the double-row sprocket 15 is respectively connected to the two sprockets 13 via chains 14. In order to facilitate the adjustment of the bidirectional lead screws 6, the rotating shaft 16 passes through the center of the double-row sprocket 15 and is provided with a hand wheel 17.

[0032] The working process of this utility model:

[0033] First, guide rails 5 are laid on both sides of the middle partition wall of the pipe gallery structure, and the grooves 8 on the bottom of the guide rails 5 are used to stably clamp and fix them on the surface steel bars. After the discharge chute 3 is spliced, it is selected whether to assemble the upper extension groove 2 according to actual needs, and the handheld telescopic rod 1 and the outer wall of the discharge chute 3 are connected by nuts. The discharge chute 3 is slidably matched with the guide wheels 7 on the bottom support legs 4. The movable plate 11 set at the discharge port 9 on the bottom plate of the discharge chute 3 is opened and closed by the rotation of the two bidirectional lead screws 6. When the bidirectional lead screw 6 rotates forward, the guide rods 10 on the two bidirectional lead screws 6 can move toward each other and approach each other under the limiting guiding action of the guide through grooves 12, thereby reducing the size of the discharge port 9, thereby controlling and reducing the discharge. Similarly, when the bidirectional lead screw 6 rotates in the opposite direction, the guide rods 10 on the two bidirectional lead screws 6 can move away from each other in their backs. At this time, the discharge port 9 is enlarged, thereby controlling and increasing the discharge, thereby effectively controlling the discharge speed and discharge amount.
