Based on the embodiments of 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.
[0017] See also Figure 1-Figure 5A trackless electric trolley furnace comprises: a trolley 2, a furnace body 12, an electric drive mechanism, a guide mechanism, a stroke control mechanism and a safety protection mechanism. The trolley 2 moves back and forth toward the furnace body 12 under the control of the electric drive mechanism, and the guide mechanism ensures that the trolley 2 maintains a stable direction during the movement, and then the forward and backward movement strokes of the trolley 2 are controlled by the stroke control mechanism. The safety protection mechanism is used to ensure the safety of the trolley 2 and the furnace body 12. The electric drive mechanism comprises: a drive motor 1, a drive gear 9, a rack 4 and a PLC controller. The drive motor 1 is arranged on one side of the lower bracket of the furnace body 12, and the shaft end of the drive motor 1 is connected to the drive gear 9, and the drive gear 9 is meshed with the rack 4. The rack 4 is arranged on the side of the trolley 2 and drives the trolley 2 to move under the drive of the drive motor 1. The PLC controller is used to control the drive motor 1. The track guide mechanism includes: channel steel 11, angle steel 10 and guide wheel 8. The number of the channel steel 11 is two, which are symmetrically arranged on both sides of the lower bracket of the furnace body 12; the number of the angle steel 10 is two, which are symmetrically arranged on both sides of the trolley 2. One side of the angle steel 10 matches the groove set in the channel steel 11. The guide wheel 8 is arranged below the channel steel 11, and the outer circle of the guide wheel 8 contacts the side wall of the trolley 2. The travel control mechanism includes: front limit switch 5, rear limit switch 7 and touch rod 6. The touch rod 6 is arranged at the center position of the front part of the trolley 2. The front limit switch 5 and the rear limit switch 7 are respectively arranged on the front and rear sides of the touch rod 6. The front limit switch 5, the touch rod 6 and the rear limit switch 7 are on the same straight line. The bottom of the trolley 2 is provided with load-bearing wheels 3. The number of the load-bearing wheels 3 is multiple and evenly arranged on the bottom surface of the trolley 2. The safety protection mechanism is composed of a plurality of small sensitive sensors, which detect the distance between the trolley 2 and the surrounding objects during its operation through the sensors. If there is a possibility of contact, the drive motor 1 will be automatically controlled to stop running to ensure safety; if the trolley 2 is overloaded or the drive motor 1 works under non-preset conditions, the sound and light alarm will be triggered to issue an emergency warning; if the trolley 2 fails to operate, it will initially self-check the cause of the failure and remind the operator to eliminate the failure in time to avoid accidents.
[0018] Embodiment: The PLC controller controls the drive motor 1 through the manual operation terminal. The shaft end of the drive motor 1 is tightly connected to the drive gear 9 through a key. Driven by the drive motor 1, the drive gear 9 meshes with the rack 4, and the trolley 2 is driven to move through the contact and movement of the drive gear 9 and the rack 4. The transmission efficiency is high, stable and reliable. The left and right strokes of the trolley 2 can be controlled by limiting the guide wheels 8 on both sides of the bracket below the furnace body 12. The channel steel 11 and the angle steel 10 on the trolley 2 are used above the guide wheel 8 to cooperate, which not only increases the structural strength of the trolley 2, but also protects the safety of the left and right strokes of the trolley 2. When the trolley 2 pushes out the furnace body 12 and moves to the maximum preset position, the touch rod 6 contacts the front limit switch 5, and the front limit switch 5 makes a feedback signal, and the operating terminal closes the drive motor 1 to stop the trolley 2 automatically; when the trolley 2 closes and runs to the maximum stroke, the touch rod 6 contacts the rear limit switch 7 to stop the trolley 2 automatically, reducing manual operation and avoiding losses to personal and property caused by manual operation errors, thereby improving the maneuverability and safety of the trolley 2. The safety protection mechanism is mainly composed of a plurality of small sensitive sensors. The sensors detect the distance from the surrounding objects during the operation of the trolley. If there is a possibility of contact, the drive motor 1 will be automatically controlled to stop running to ensure safety; if the trolley 2 is overloaded and the drive motor 1 works under non-preset conditions, the sound and light alarm will be triggered to issue an emergency warning; if the trolley 2 fails to operate, it will initially self-check the cause of the failure and remind the operator to eliminate the failure in time to avoid accidents.
