Description

Technical Field

[0001] The utility model relates to the technical field of turnover carts, and particularly relates to a turnover cart for an annealing furnace to enter the furnace. Background Technique

[0002] Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling at an appropriate speed. The purpose is to reduce hardness, improve machinability; reduce residual stress, stabilize dimensions, reduce deformation and crack tendency; refine grains, adjust the structure, and eliminate structure defects. Exactly speaking, annealing is a heat treatment process for materials, including metal materials and non-metal materials, and the annealing purpose of new materials also has similarities and differences with traditional metal annealing. And an annealing furnace is a device for annealing the said materials.

[0003] During the use of the annealing furnace, the feeding of materials needs to be completed through a turnover cart. For example, the feeding mechanism of a horizontal annealing furnace with the publication number of CN220183341U, which relates to the field of annealing equipment, includes an annealing furnace, a furnace door, and a trolley. The trolley is slidably distributed at the feeding port structure of the annealing furnace. A sliding groove is vertically opened at the top of the trolley, and a moving table is vertically distributed at the top of the trolley. A pulley is vertically installed at the bottom of the moving table. A plug board is slidably installed on one side of the trolley. A locking groove is horizontally opened at the side end of the moving table. The plug board and the locking groove are symmetrically distributed in the horizontal direction for limiting and fixing the moving table. By adding a moving table on the trolley in the utility model, the user puts the materials above the moving table, so that the trolley drives the moving table to move into and out of the annealing furnace together. After the heating and annealing operation is completed, the user can move the moving table with the materials away together. Different from the traditional lifting feeding method, this method is more rapid and convenient.

[0004] There are some problems in the above technical solution during use. When the above technical solution turns over materials, the turnover quantity of the materials is limited, and the internal space of the annealing furnace cannot be utilized maximally. Moreover, it is difficult to ensure the stability of the materials after being placed.

[0005] Therefore, it is very necessary to invent a turnover cart for an annealing furnace to enter the furnace to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a turnover cart for an annealing furnace to enter the furnace to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A turnover cart for entering an annealing furnace, comprising a vehicle frame. At the four corners of the upper surface of the vehicle frame, support plates are fixedly arranged, and the support plates are arranged in a "C" - shaped structure. A plurality of positioning holes are penetrated through the outer side wall of the support plate. Between the four support plates, there is a material basket. At the four corners of the outer side wall of the material basket, insertion tubes are fixedly arranged. Inside the insertion tubes, positioning rods are inserted, and the positioning rods correspond to the positioning holes. In the middle of the outer side wall of the insertion tube, a strip - shaped groove is penetrated. At both ends of the strip - shaped groove, card slots are opened. At one end of the positioning rod, a limiting rod is fixedly arranged, and the limiting rod corresponds to the card slot. At both top ends of the two sides of the material basket, handles are fixedly arranged. At both ends of the lower surface of the vehicle frame, support feet are fixedly arranged. At the four corners of the lower surface of the vehicle frame, support arms are movably arranged through pin shafts, and at the bottom end of the support arm, track wheels are movably arranged through pin shafts.

[0008] Preferably, between two adjacent support arms, a transmission arm is movably arranged through a pin shaft, and between the two transmission arms, a transmission rod is fixedly arranged.

[0009] Preferably, in the middle of the transmission rod, a movable arm is movably arranged through a pin shaft. At the top end of the movable arm, a movable plate is movably arranged through a pin shaft, and the movable plate is in contact with the lower surface of the vehicle frame.

[0010] Preferably, in the middle of one end of the lower surface of the vehicle frame, a fixed frame is fixedly arranged, and the movable plate penetrates through the inside of the fixed frame.

[0011] Preferably, in the middle of one end of the vehicle frame, a positioning seat is fixedly arranged.

When the bottom end of the track wheel 13 moves below the support leg 11, the frame 1 is lifted, and the support leg 11 is separated from the ground. At this time, the frame 1 can be moved through the track wheel 13. When the bottom end of the track wheel 13 moves above the support leg 11, the track wheel 13 is separated from the ground, and the frame 1 is placed through the support leg 11. At this time, the stability of the frame 1 placement can be ensured.
