Description

Technical Field

[0001] The utility model relates to the technical field of concrete transfer equipment, in particular to a lifting and forking dual-purpose UHPC pouring hopper. Background Art

[0002] Ultra-High Performance Concrete (UHPC) is an ultra-high performance cement-based composite material with ultra-high strength, ultra-high toughness, high durability and good volume stability. It is mainly composed of silica fume, cement, fine aggregate and steel fiber based on the "maximum density theory". Compared with ordinary concrete, "ultra-high performance concrete" mainly includes two aspects of "ultra-high" - ultra-high mechanical properties and ultra-high durability. The ultra-high mechanical properties of UHPC are mainly manifested in compressive strength of more than 120MPa and flexural strength of more than 18MPa. At the same time, it has excellent ductility due to the incorporation of steel fibers in the components; on the other hand, the ultra-high durability of UHPC is mainly manifested in excellent chloride ion impermeability and freeze-thaw resistance, which mainly comes from its internal dense microstructure. The design life of the UHPC structure can reach more than 200 years. This material is now mainly used in large-span steel box girder bridge deck pavement and key parts of the bridge body.

[0003] However, UHPC has a high viscosity and is prone to wall hanging during mixing and transportation. Therefore, commercial mixing plants generally do not prepare UHPC. It is necessary to build a professional mixing plant on site and transport and pour it on site, and use a bucket for mid-transfer. However, during the transportation process, a crane and a forklift are needed to transport the bucket. Different transportation methods have different force modes on the bucket, which will also cause damage to different parts of the bucket. The high frequency of bucket transportation during use leads to excessive cumulative damage to the bucket, resulting in premature damage to the bucket, affecting the construction progress, and easily leading to material waste. Therefore, a special UHPC casting bucket with a dedicated lifting fork is required. Summary of the invention

[0004] The utility model aims to provide a UHPC pouring hopper with a lifting fork for solving the problems in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A UHPC pouring hopper with a lifting fork comprises a hopper barrel and a support frame supporting the hopper barrel; a plurality of lifting ring assemblies are arranged above the support frame, a reinforcing member is arranged at the lower half of the support frame, and a forklift position is arranged below the support frame; a discharge channel is arranged below the hopper barrel, an openable and closable valve is arranged at the discharge channel, and a retractable and adjustable guide tube assembly is also arranged below the discharge channel.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] like Figure 1 and Figure 2 As shown, a lifting fork dual-purpose UHPC pouring hopper includes a hopper barrel 1 and a support frame supporting the hopper barrel 1; a plurality of lifting ring assemblies are provided above the support frame, a reinforcing member is provided at the lower half of the support frame, and a forklift position is provided below the support frame; a discharge channel 2 (discharge port) is provided below the hopper barrel, an openable and closable valve 3 is provided at the discharge channel 2, and a retractable and adjustable guide tube assembly is also provided below the discharge channel 2.

[0030] The lifting and forking dual-purpose UHPC casting hopper has improved its supporting and moving modes, and can be transported as a whole by lifting or forking to meet different process requirements; and reinforcing components are set at weak stress locations to enhance the overall bearing capacity of the hopper, increase the risk of material leakage during transportation, greatly reduce UHPC material loss, and have very obvious economic benefits.

[0031] Specifically, the forklift station can use a forklift to transport the hopper carrying UHPC materials from the mixing site to the casting site. When the UHPC materials are transported to the casting site, the lifting ring assembly can be used as a lifting point, and a crane is used to transport the hopper to the casting area for horizontal and uniform material distribution. The provision of the reinforcing member can prevent premature damage to the hopper barrel due to the change of the force point during different transportation methods, and can increase the service life of the hopper barrel, so as to avoid leakage of UHPC or even dumping into waste in the middle, thereby reducing the consumption cost of UHPC.

[0032] Since the hopper cylinder can be forked or lifted, in order to facilitate forklift transportation, the position of the discharge channel will be inside the support frame, that is, it will not be lower than the entire support frame. This will make it inconvenient to pour the discharge channel or connect the pouring pipe during pouring. Therefore, a retractable and adjustable guide tube assembly is provided, which can be retracted into the support frame during transportation and lowered during pouring to facilitate discharge or connection to an external pouring pipe.

[0033] Furthermore, the support frame includes multiple support columns 4, the upper parts of the support columns 4 are welded to the outer periphery of the hopper barrel 1, forklift lifting steel sections 7 are respectively provided between the bottoms of adjacent support columns 4, the forklift position is provided below the forklift lifting steel sections 7, and the reinforcing member is connected between the adjacent support columns 4.

[0034] The forklift lifting steel 7 has high strength and can share the force. Combined with the arrangement of the reinforcing member and the forklift position, the forklift can well lift the entire hopper for transportation, thereby ensuring its stability.

[0035] Furthermore, the reinforcing member includes a horizontal reinforcing rod 5 disposed between the support columns 4, and an oblique reinforcing rod 6 connected to the horizontal reinforcing rod 5 and the support columns 4. The arrangement of the horizontal reinforcing rod 5 and the oblique reinforcing rod 6 can optimize the stress points of the support frame, strengthen the stress performance at the node, and reduce the uneven stress during transportation.

[0036] Further, combined with Figure 3As shown, the forklift position includes a slot 8 arranged below the forklift lifting steel 7, and a lifting reinforcement plate 9 connected between the opposite forklift lifting steels 7, and the bottom surface of the lifting reinforcement plate 9 is flush with the bottom of the slot 8.

[0037] The slot 8 has a certain limiting effect. When the fork arm of the forklift is inserted into the slot 8, the deviation and shaking of the carried object can be prevented. The setting of the lifting reinforcement plate 9 can increase the contact area between it and the fork arm, which can optimize the force and avoid excessive local force.

[0038] Furthermore, a plurality of legs 13 are provided below the support frame. The legs 13 can lift the support frame to a certain height, and the legs can also be placed in some environments that require fixed support. The legs 13 are welded to the support column or the forklift lifting steel using φ60*3 seamless steel pipes, and the material specification of the legs is not less than Q235.

[0039] Furthermore, the lifting ring assembly includes an ear plate 10, a pair of connecting rods 11 are provided below the ear plate 10, the connecting rods 11 are welded and fixed to the support frame and / or the hopper barrel, and a lifting ring 12 is connected to the ear plate 10 through a pin. The lifting ring 12 arranged in this way has a high connection stability, and the lifting ring itself can also be properly rotated for easy lifting. The load-bearing capacity of the lifting ear is not less than 1 ton.

[0040] Further, combined with Figures 4 to 6 As shown, the guide cylinder assembly includes a telescopic cylinder 14, and flange edges 15 are provided at both ends of the telescopic cylinder 14. A pull rope 17 is provided on the lower flange edge 15 through a connecting seat 16. The pull rope 17 passes through the upper flange edge (the flange edge and the flange of the discharge channel are provided with corresponding rope threading holes 21) and is provided with a limiting ring 18. A buckle 19 is provided at the end of the pull rope 17, and a lock buckle 20 connected to the buckle 19 is provided on the outer periphery of the discharge channel 2.

[0041] The flanges 15 are arranged at both ends of the telescopic cylinder so that they can be connected to the flanges of the discharge channel so that they are located below the discharge channel; if necessary, the flange below can also be used to connect the pouring pipe. The pull rope 17 can lift the flange below. When the buckle 19 at the end of the pull rope 17 is connected to the lock buckle 20, the telescopic cylinder 14 is in a retracted state, which is basically above the support frame. When the pull rope is released, the flange below drops down by itself, and the telescopic cylinder 14 is in an expanded state and can be fully exposed from the bottom of the support frame; the limit ring 18 plays a limiting role to limit the position of the pull rope 17. The setting of the guide cylinder assembly does not affect the normal discharge operation of the discharge channel, nor does it affect the opening and closing of the valve. The telescopic cylinder 14 is a metal telescopic cylinder, a plastic telescopic cylinder or a rubber bellows.

[0042] Furthermore, the hopper barrel 1 includes an upper cylindrical portion 101 and a lower truncated cone portion 102, and a cylindrical discharge channel 2 is arranged below the truncated cone portion 102; the diameter of the cylindrical portion 101 is not less than 0.5m, the diameter of the discharge channel 2 is not less than 0.15m, and the heights of the cylindrical portion 101 and the truncated cone portion 102 are not less than 0.3m. The valve is a scissor-type discharge valve, and can also be a valve of a valve plate, a flap, or the like.

[0043] Furthermore, a vibration motor is installed on the outer wall of the truncated cone portion 102 through a motor seat. By setting the vibration motor, the truncated cone portion can be vibrated during the discharge process to reduce the adhesion and wall hanging of the UHPC material, which is beneficial to the discharge and pouring.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
