Description

Technical Field

[0002] A trolley furnace is an industrial heat treatment equipment, commonly used for processes such as metal heating, heat treatment and smelting. It has a moving trolley that can load the workpiece to be processed into the furnace and then move it to the appropriate position for heating or processing. The trolley is usually made of high-temperature resistant materials and can withstand working conditions in high-temperature environments.

[0003] Existing trolley furnace charging devices mostly use cranes, bridge cranes or other types of lifting equipment to lift heavy workpieces from the ground or other locations and place them on the trolley, and then move them into the furnace for heating or processing. If traditional lifting equipment is used in the transportation of a single workpiece, it is appropriate. However, in the transportation of multiple workpieces, the use of traditional lifting equipment for single and multiple transportation takes a long time. If multiple devices are used to work at the same time, cross-operation will cause the traditional lifting equipment to be occupied, posing a safety hazard. Utility Model Content

[0028] Example 1:

[0029] Combine Figures 1 to 4 The shown combined material fork structure for a trolley furnace includes a gantry 1 for supporting the entire device, a crossbeam 2 is fixedly installed above the gantry 1, a lifting beam 9 is vertically arranged on the crossbeam 2, and the lifting beam 9 can move on the crossbeam 2 in a direction perpendicular to the horizontal plane, a first hinge support 10 is fixedly installed near the bottom of the lifting beam 9, a second hinge support 11 is fixedly arranged below the crossbeam 2, and a hydraulic cylinder 12 is arranged perpendicular to the crossbeam 2, the output end of the hydraulic cylinder 12 is fixedly arranged on the first hinge support 10, and the other end is fixed on the second hinge support 11. When the hydraulic cylinder 12 is started, the output end of the hydraulic cylinder 12 is extended, pushing the lifting beam 9 to move vertically downward, and the output end of the hydraulic cylinder 12 is shortened, causing the lifting beam 9 to move vertically upward.

[0030] Specifically, such as Figure 1As shown, the first hinged beam 13 is inclined to the horizontal plane. One end of the first hinged beam 13 is fixed to the door frame 1 , and the other end is fixed to the crossbeam 2 to support the crossbeam 2 and increase the rigidity of the crossbeam 2 .

[0031] like Figure 1 As shown, one end of the second hinged beam 14 is fixed on the lifting beam 9, and a movable frame 3 is provided on the crossbeam 2. The movable frame 3 can move in a direction parallel to the crossbeam 2. One end of the second hinged beam 14 is hinged to the movable frame 3, and the second hinged beam 14 and the first hinged beam 13 are hinged.

[0032] like Figure 1 and Figure 2 As shown, a slide rail 5 is provided in the beam 2, and the slide rail 5 is parallel to the horizontal plane along the beam 2. A fixed frame 7 is fixedly installed at one end of the movable frame 3, and a pulley 6 is installed in the fixed frame 7. A motor 4 for driving the pulley 6 to rotate is installed on the movable frame 3, and the pulley 6 is slidably connected to the slide rail 5 on the beam 2.

[0033] like Figure 1 As shown, a material fork 8 is fixedly connected to the bottom of the lifting beam 9, and the material fork 8 is used to load and unload heavy objects into the trolley furnace.

[0034] In the above structure, the motor 4 is started, the pulley 6 rotates and performs linear motion in the slide rail 5, thereby pushing the mobile frame 3 to perform linear motion on the crossbeam 2. Since the first hinged support beam 13 is fixed, one end of the second hinged support beam 14 is connected to the mobile frame 3, and the other end is fixedly connected to the lifting beam 9. The first hinged support beam 13 and the second hinged support beam 14 are hinged. When the mobile frame 3 moves, the angle between the first hinged support beam 13 and the second hinged support beam 14 changes, thereby changing the position of the lifting beam 9 connected to the second hinged support beam 14, thereby changing the position of the material fork 8 relative to the ground.

[0035] As a result, the hydraulic cylinder 12 is started, and the output end of the hydraulic cylinder 12 is extended, pushing the lifting beam 9 to move vertically downward. The output end of the hydraulic cylinder 12 is shortened, causing the lifting beam 9 to move vertically upward. The motor 4 is started to rotate the pulley 6 in the slide rail 5, and the movable frame 3 moves on the beam 2 in the direction away from the lifting beam 9, and the material fork 8 moves in the opposite direction relative to the pulley 6. If the movable frame 3 moves on the beam 2 in the direction close to the lifting beam 9, the material fork 8 moves in the opposite direction relative to the pulley 6.

[0036] Example 2:

[0037] In combination with a combined material fork structure for a trolley furnace shown in Example 1, a plurality of cross beams 2 are provided on the door frame 1, such as four cross beams 2 fixedly installed, and the four cross beams 2 are parallel to each other. A lifting beam 9 that can move in a direction perpendicular to the horizontal plane is provided on each cross beam 2, and each lifting beam 9 has the same length and the same height relative to the ground. A first hinge support 10 is fixedly installed near the bottom position of each lifting beam 9, and a second hinge support 11 is fixedly provided under each cross beam 2, and the first hinge support 10 is fixed at the first hinge support. The relative positions on the seats 10 are the same, that is, each first hinge support 10 and the second hinge support 11 are at the same height relative to the ground. A hydraulic cylinder 12 is provided perpendicular to the crossbeam 2. The output end of the hydraulic cylinder 12 is fixedly provided on the first hinge support 10, and the other end is fixed on the second hinge support 11. When the hydraulic cylinder 12 is started, the output end of the hydraulic cylinder 12 is extended, pushing the lifting beam 9 to move vertically downward. The output end of the hydraulic cylinder 12 is shortened, causing the lifting beam 9 to move vertically upward. A material fork 8 is fixedly connected to the bottom of each lifting beam 9.

[0038] like Figures 1 to 4 As shown, each crossbeam 2 is provided with a movable mobile frame 3, and the pulley 6 of each mobile frame 3 is slidably connected to the slide rail 5 of the crossbeam 2. The pulley 6 is driven by the motor 4 provided on the mobile frame 3. On the four mobile frames 3, the four pulleys 6 can be driven by the motor 4 to rotate at the same time, or each pulley 6 can rotate individually.

[0039] like Figures 1 to 4 As shown, a first hinged beam 13 inclined to the horizontal plane is fixedly arranged between each crossbeam 2 and the portal frame 1, and the planes where any two first hinged beams 13 are located are parallel to each other. Each first hinged beam 13 is hinged to a second hinged beam 14, and one end of the second hinged beam 14 is fixedly connected to the lifting beam 9, and the other end is fixedly connected to the movable frame 3. The projections of the four first hinged beams 13 on the horizontal plane perpendicular to the horizontal plane coincide, and the projections of the four second hinged beams 14 on the horizontal plane perpendicular to the horizontal plane coincide, so as to ensure that the position of each first hinge support 10 relative to the crossbeam 2 and the portal frame 1 is the same, and the position of the second hinged beam 14 relative to the crossbeam 2, the movable frame 3 and the lifting beam 9 is the same.

[0040] Thus, a single hydraulic cylinder 12 is started, and the output end of the hydraulic cylinder 12 is extended, pushing the lifting beam 9 connected thereto to move vertically downward, and the output end of the hydraulic cylinder 12 is shortened, causing the lifting beam 9 connected thereto to move vertically upward; at the same time, multiple hydraulic cylinders 12 are started, and the output ends of the started multiple hydraulic cylinders 12 are extended, pushing the multiple lifting beams 9 connected thereto to move vertically downward, and the output ends of the started multiple hydraulic cylinders 12 are shortened, causing the multiple lifting beams 9 connected thereto to move vertically upward; a single motor 4 is started, causing the pulley 6 to rotate in the corresponding slide rail 5, and the mobile frame 3 moves on the beam 2 in the direction away from the lifting beam 9, and the material fork 8 moves in the opposite direction relative to the pulley 6. If the mobile frame 3 moves on the cross beam 2 toward the lifting beam 9, the material fork 8 moves in the opposite direction relative to the pulley 6; at the same time, start multiple motors 4 to make the driven multiple pulleys 6 rotate in the corresponding slide rails 5 at the same time, and the rotation directions of the rotating pulleys are the same. The corresponding mobile frames 3 move on the cross beam 2 away from the lifting beam 9 at the same time, and the corresponding multiple material forks 8 move in the opposite direction relative to the pulley 6 at the same time. If the mobile frame 3 moves on the cross beam 2 toward the lifting beam 9 at the same time, the corresponding multiple material forks 8 move in the opposite direction relative to the pulley 6 at the same time.

The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
