Description

Technical Field

[0001] The utility model relates to a self-unloading threaded steel cut head collecting hopper. Background Art

[0002] The rebar head cutting hopper is a modern steel processing equipment, mainly used for the head cutting of rebar. The shearing equipment bends the head or excess tail of the rebar into a short length and collects it as waste during the shearing process. Traditional head and tail hoppers have many problems in the process of handling and conveying, such as poor unloading, low efficiency, and potential safety hazards. In the bar production line of a steel enterprise's rolling mill, the head cutting collection hopper is behind the length shear. The hopper is an open material box design. Each dumping of the hopper requires close intervention by personnel to complete. During the unloading process, personnel must invert the wire rope. The impact during the cutting and flipping is large, which causes great damage to the inverted vehicle. During the process, personal injury accidents often occur in human-machine contact. During the operation, there is a phenomenon of crooked and oblique lifting of the lifting machinery, and there is a high risk factor of direct contact between man and machine, the labor intensity of personnel is large, and the efficiency is low. It does not meet the requirements of equipment intrinsic safety quality in safe production. Therefore, it is required to completely solve the spatial intersection and human-machine contact in the lifting process through design optimization.

[0003] There are currently three forms used at home and abroad:

[0004] 1. Jaw self-unloading hopper: The lower end of the gantry hanger is connected to a bucket body, and the lower end of the bucket body is provided with a symmetrically arranged left palate plate and a right palate plate, both ends of the left palate plate and the right palate plate are connected to the two ends of the bucket body through a rotating shaft, and both end surfaces of the left palate plate and the right palate plate are provided with a top shaft, and one end of the left palate plate and the right palate plate are connected to each other through a balancing connecting rod. The present invention uses the lever principle to enable the left palate plate and the right palate plate to be automatically closed under the action of their own weight.

[0005] 2. Hoisting sling hopper: Conventional hoppers are hoisted by wire ropes or other slings, and the hoppers are tipped over and unloaded by changing different lifting points. During the unloading process, the personnel need to invert the wire rope through the lifting points to tip the hopper, and the whole process has a large impact, which causes great damage to the transport vehicle, and there is human-machine contact, so the safety factor is low.

[0006] 3. Bucket type hopper: suitable for forklifts to load, unload and transport materials.

[0007] The above methods are not suitable for the transportation and loading and unloading of cut materials on the production line.

The utility model has the advantages of automatic unloading and convenient transportation. Summary of the invention

[0012] The utility model aims to provide a self-unloading threaded steel cut head collecting hopper, which is suitable for the reverse transportation and loading and unloading of the cut head materials of the production line and is convenient and safe to use.

[0013] The technical solution adopted by the utility model is a self-unloading threaded steel cut head collecting hopper, including a hopper body, a movable bottom plate is arranged at the bottom of the hopper body, one end of the movable bottom plate is hinged to the bottom of the hopper body, and the other end of the movable bottom plate is abutted against a closer arranged at the other end of the bottom of the hopper body, the closer includes a closer guard plate, a Z-shaped closer actuator is hinged on the closer guard plate, the bottom end of the closer actuator is abutted against the free end of the movable bottom plate, the upper end of the closer actuator is respectively connected to a reset spring and a closer control chain, the lower end of the reset spring is connected to the closer guard plate, the upper end of the closer control chain bypasses the guide wheel arranged on the side wall of the hopper body and is connected to the auxiliary hook of the crane, and lifting ears are respectively arranged on both sides of the hopper body, and chains are arranged on the lifting ears to connect with the main hook of the crane.

[0014] During operation, when the hopper is full, the main hook of the crane hangs the main lifting lug, and the auxiliary hook hangs the opener and closeer control chain, and they move at the same time to lift the entire hopper and transport it to the inverted material transport vehicle. The auxiliary hook moves to dump the cut waste into the inverted material transport vehicle.

[0015] The entire unloading process is completed by using the actions of the main and auxiliary hooks, avoiding human involvement and achieving human-machine separation. This plays a great role in the safety of the operators and fundamentally realizes the requirements of the essentialization of the equipment.

[0016] The hopper is originally placed horizontally on a flatbed trolley, full of rebar cut ends. The main hook is slowly lifted, and the actuator of the closer is in a closed state under the gravity of the cut ends. The entire hopper is lifted and moved out of the foundation pit, and then transported horizontally to the side of the transport vehicle, placed on the ground, and hung on the auxiliary hook. The main and auxiliary hooks are lifted and transported to the inside of the transport vehicle at the same time, and placed in the vehicle compartment. The auxiliary hook is lifted to fully open the actuator of the closer, and then the main and auxiliary hooks are lifted upward synchronously. During this process, it should be lifted slowly. The movable bottom plate slowly rotates around the support pin shaft without the constraint of the actuator of the closer to open. At this time, the cut end waste slides from the opened movable bottom plate into the compartment of the transport vehicle, and the main hook is continued to be lifted to dump all the materials in the hopper.

[0017] The main hook of the crane hoists the hopper as a whole out of the area of ​​the transport vehicle, and slowly places the hopper on the ground. During this process, the auxiliary hook is not stressed and completely relaxed, and the movable side of the movable floor touches the ground first, so that the movable floor slowly closes. When it contacts the actuator of the closer, it will push the actuator of the closer along the bottom slope of the actuator. After it is fully closed, the actuator of the closer resets and locks the movable floor under the action of the reset spring, completing the automatic closing of the hopper after clearing the warehouse, and then the main hook of the crane hoists it to the original station for the next round of collection operations. It should be emphasized that the movable floor adopts a belly plate structure to provide space for the action of the actuator, ensure the normal opening and closing of the actuator of the closer, and also ensure that the hopper avoids collisions and misoperation accidents during the transport process. In addition, an opener and closeer guard plate is also set at the closer to prevent misoperation accidents caused by collisions during the transport of the hopper. Thirdly, a reset spring is designed at the actuator to ensure that the opener and closeer automatically lock when the movable floor is closed.

[0018] The utility model realizes non-tipping unloading and safe isolation of man and machine. The floor adopts a belly plate structure to provide space for the action of the actuator and ensure the normal opening and closing of the actuator of the closer at the closer. The closer is also provided with an opener and shutter guard plate to prevent misoperation accidents caused by collision during the hopper reversal process. Thirdly, a reset spring is designed at the actuator to ensure the automatic locking function of the opener and shutter when the movable bottom plate is closed. During the whole process, manual inversion of the wire rope is avoided to achieve smooth lifting and improve the working efficiency. Due to its simple structure, convenient maintenance and large load-bearing capacity, it is suitable for lifting operations with vertically distributed equipment. Since the mechanism of the invention is relatively simple, the production line transformation is easy to implement and basically no changes are required to the existing equipment. It greatly improves the production efficiency of steel processing and reduces the labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS
