Description

a concrete bucket

technical field

The invention belongs to the field of concrete construction equipment, and in particular relates to a concrete hanging tank, in particular to a remote-controlled opening and closing concrete hanging tank.

Background technique

In large-scale concrete pouring construction operations, there are many ways to transport concrete aggregates into the warehouse. The existing horizontal transportation of concrete in China generally adopts the method of warehousing by car or belt conveyor. Car warehousing can effectively guarantee the quality of concrete and is more economical, but it requires a flat road surface, which is not suitable for construction areas with large height differences. The belt conveyor has a high transportation capacity, but it is easy to cause aggregate separation and requires a large investment. Therefore, use the cable crane or door, tower crane and other vertical lifting transportation equipment on the construction site, adopt the transportation method of hanging the tank without unhooking, the pouring method is flexible, and the construction efficiency is high. It is widely used in the concrete construction site of large-scale water conservancy projects. Existing hanging tanks are generally vertical, and the hanging tank has a certain height, and the material is fed in from the upper end through pumping. This method requires high equipment and high construction costs.

Commonly used concrete hanging tanks generally adopt manual operation to control the opening and closing of the bucket door. Among them, the pure manual tank is opened manually. Although it can be opened and closed at any time according to the needs of the site, the labor intensity of the operator is high and the safety is poor. The valve can easily open and close the bucket door, but due to the limited energy storage, the stored energy can only make the bucket door open and close three times. If there is a need for unloading more than three times, the hanging tank needs to be grounded to store energy before lifting. The construction site also affects the construction efficiency.

The cylinder 7 of the hydraulic system is hinged with the bucket door 8 through the bucket door hinge seat 13; 6. The remote control hydraulic system composed of the hydraulic cylinder 7, wherein the electric control box 4, the motor/hydraulic pump 5, the hydraulic oil tank 6, and the hydraulic cylinder 7 are conventional commercially available products. When in use, the electric control box 4 is commanded to start the motor/ The hydraulic pump 5 pressurizes or decompresses the hydraulic oil tank 6, and the hydraulic oil tank 6 moves the piston of the hydraulic oil cylinder 7 through the oil pipe to realize the opening and closing of the bucket door 8.

Boom 1 and boom 1a represent two kinds of use states among Fig. 2, and boom 1 represents the state when hanging tank receiving materials, and boom 1a represents the state when hanging tank is ready to lift.

As shown in Figures 1 to 4, the boom 1 is assembled and welded by steel plate and section steel to form a stable bracket, which is hinged with the tank so that the boom can rotate around the hinge axis. When loading, the boom leans against the top of the tank, exposing the feed hopper to the front, which is convenient for dump trucks or tank trucks to feed. The feed hopper 2 is mainly assembled and welded by warehouse wall steel plates and reinforced steel. The width of the inner cavity of the feeding hopper is 3.1m, which meets the requirement of the unloading width of the dump truck. The discharge hopper 3 is mainly welded by the steel plate of the warehouse wall and the reinforced steel, wherein the discharge part is welded by the steel plate to form a structure with a large top and a small bottom, and then a hopper structure is set at the exit to facilitate the control of the discharge volume.

The electric motor 5 is the power source of the active hydraulic system and provides working pressure for the hydraulic system. The hydraulic oil tank 6 is designed with a reasonable capacity according to the working flow of the hydraulic system. At the same time, it is reasonably arranged on the side of the tank body discharge hopper 3 to avoid being damaged by collision during construction and use. In this example, all electrical equipment is installed on the steel plate of the landing gear 14. within frame boundaries. The hydraulic cylinder 7 is configured according to the opening and closing force of the bucket door 8. The tail of the oil cylinder 7 is connected with the cylinder support designed on the discharge hopper 3, and the piston head is hinged with the bucket door. According to construction needs, the opening and closing action of the bucket door 8 is realized. The bucket door 8 is a two-leaf split structure, and is mainly composed of side plates 11 on both sides, a bottom plate 12 and meshing gears 10 . The bucket door 8 is fixed on the discharge hopper by the bucket door hinge pin 9, and the bucket door 8 can be rotated with the hinge pin 9 as an axis. Engagement gear 10 each unilateral bucket door top is inlaid with 1/4 meshing gear, meshes with the opposite bucket door gear, guarantees that when one side is opened, the other side is also opened; when one side is closed, the other side is also closed. The side plate 11 of the bucket door is connected with the bottom plate 12 of the bucket door, and simultaneously serves as a support for the bottom plate. The bottom plate 12 of the hopper door is used to close the discharge hopper door 8 . The bucket door hinge seat 13 is connected with the 7 piston rods of the door opening cylinder, and according to the construction needs, the bucket door is opened and closed.

As shown in the figure, after the hanging tank is hoisted, the hanging tank is in the vertical state. Close the discharge hopper door 8 and move to the ground to receive materials again. When the hanging tank touches the ground, the protruding part 14b first touches the ground. Due to the action of gravity, the hanging tank falls to the ground along the inclined edge, and then receives the material after falling to the ground along the arc structure 14a. The whole process does not require direct contact and operation by construction personnel, which is convenient and safe.

The working cycle process of the remote-controlled hanging tank: Material receiving: lay the horizontal tank flat on the special material receiving platform or flat ground, and then receive the material from the feeding hopper of the horizontal tank through a dump truck or a concrete tanker. Hoisting: After receiving materials, the vertical transport equipment lifts the hanging tank and transports it to the cloth position, so that the lying tank falls to an appropriate height. Cloth: Connect the power supply and start the hydraulic system. At this time, you can complete the cloth operation by remote control or operating the corresponding buttons on the electric control box of the tank body, and move the cloth at multiple points and times according to actual needs. Hoisting: After the cloth is finished, the horizontal tank is hoisted by the vertical transportation equipment to the material receiving point. Compared with the self-storage hydraulic horizontal tank, the working pressure is provided by the hydraulic system, so that the hydraulic cylinder can work at any time to realize the opening and closing of the bucket door. It is very suitable for construction sites that require multiple points of distribution or the amount of distribution is strictly controlled, and can realize remote control Operation, low labor intensity and high safety.
