Description

Technical Field

[0001] This utility model belongs to the field of drying equipment, specifically relating to a drying oven door lifting device after a power outage. Background Technology

[0002] After a power outage in a tunnel drying oven, the products inside must be removed from the oven as quickly as possible to prevent discoloration due to over-drying. Currently, the opening and closing of the tunnel drying oven door is controlled by a motor, and its location is unpredictable. In the event of a power outage, the oven door can only be lifted manually, which is extremely dangerous and inefficient. Utility Model Content

[0003] In order to solve the above problems of the prior art, this utility model proposes a drying oven door lifting device after power failure.

[0004] The specific solution of this utility model is as follows:

[0005] A drying oven door lifting device after a power outage, characterized in that it includes a lower support assembly, a motor fan connecting shaft disc, a right-angle commutator, and a crank handle. The lower support assembly includes a horizontal support and several vertical support legs. The longitudinal axis of the motor fan connecting shaft disc passes through the middle of the lower support assembly. The bottom of the shaft disc has power transmission shafts corresponding to the gaps between the fan blades. The right-angle commutator is connected to the upper end of the longitudinal axis of the motor fan connecting shaft disc and is connected to the crank handle on its side.

[0006] Preferably, the upper surface of the lower support assembly has a bearing housing surrounding the longitudinal axis of the motor fan connecting shaft disk, and a deep groove ball bearing and an elastic retaining ring for A-type bore are installed in the bearing housing.

[0007] Preferably, the crank handle is fixed to the connecting shaft of the right-angle commutator by a flexible cylindrical pin.

[0008] Preferably, the right-angle commutator is fixedly connected to the outer periphery of the longitudinal axis connection point of the motor fan connecting shaft disk via a connecting sleeve.

[0009] Preferably, a commutator connecting frame is connected between one side of the right-angle commutator and the support leg surface of the corresponding side of the lower support assembly. The commutator connecting frame includes vertical surfaces that respectively fit against the right-angle commutator and the support leg surface, and an inclined surface connecting the two vertical surfaces.

[0010] More preferably, the commutator connecting frame is connected to the vertical surface of the right-angle commutator via a system of internal hexagonal head screws, Class A flat washers, standard elastic washers, and Type 1 hexagonal nuts.

[0011] Preferably, the horizontal support of the lower support assembly is connected to the bearing housing via a system of Class A flat washers, standard elastic washers, and hexagonal head bolts.

[0012] Preferably, the lower support assembly has fixing screws at its bottom.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention is applicable to situations where a tunnel-type drying oven experiences a power outage. When a power outage occurs, the tunnel-type drying oven door lifting motor cannot operate on its own. However, the motor's cooling fan is tightly connected to the rotating shaft, and the motor shaft remains connected to the oven door lifting chain. The movement of the rotating shaft can still cause the chain to move. Therefore, rotating the cooling fan and using external force to move the rotating shaft can achieve the effect of raising and lowering the oven door.

[0015] Specifically,

[0016] 1. This utility model uses a rotating motor fan to drive the drying oven door, avoiding the possibility of injury from being lifted manually during a power outage;

[0017] 2. This utility model operates from the location of the furnace door lifting motor, away from the furnace door, thus avoiding burns that may be caused by manually lifting the drying furnace door;

[0018] 3. The unique structure and transmission method of this utility model facilitate the installation and dismantling of the entire device. Attached Figure Description

[0024] Example

[0025] like Figure 1-2The diagram shows a drying oven door lifting device after a power outage, comprising a lower support assembly 1, a motor fan connecting shaft disk 5, a right-angle commutator 7, and a crank handle 18. The lower support assembly 1 includes a horizontal support and several vertical support legs 14. The longitudinal axis of the motor fan connecting shaft disk 5 passes through the middle of the lower support assembly 1. The bottom of the shaft disk has corresponding motor cooling fan power transmission shafts 19 distributed on the surface of the shaft disk (only one is shown in the line of sight in the figure due to cross-section reasons; in reality, three are arranged at 120° intervals along the circumference). The right-angle commutator 7 is connected to the upper end of the longitudinal axis of the motor fan connecting shaft disk 5 and is connected to the crank handle 18 on the side.

[0026] The upper surface of the lower support assembly 1 has a bearing seat 2 surrounding the longitudinal axis of the motor fan connecting shaft disk 5. A deep groove ball bearing 3 and an A-type retaining ring 4 are installed in the bearing seat 2. The right-angle commutator 7 is fixedly connected to the longitudinal axis of the motor fan connecting shaft disk 5 by a connecting sleeve 6.

[0027] A commutator connecting frame 9 is connected between one side of the right-angle commutator 7 and the surface of the leg 14 of the corresponding lower support assembly. The commutator connecting frame 9 includes a vertical surface that is respectively attached to the surfaces of the right-angle commutator 7 and the leg 14, and an inclined surface that connects the two vertical surfaces.

[0028] The commutator connecting bracket 9 is connected to the vertical surface of the right-angle commutator via a system of hexagonal head screws 13, Class A flat washers 10, standard elastic washers 11, and type 1 hexagonal nuts 16. The horizontal bracket of the lower bracket assembly 1 is connected to the bearing seat 2 via a system of Class A flat washers 10, standard elastic washers 11, and hexagonal head bolts 12. The lower bracket assembly 1 has a fixing screw 17 at its bottom.

[0029] The specific operation method of this embodiment is as follows:

[0030] 1. Remove the motor heat sink cover, place the lower bracket assembly 1 on the cooling fan, and insert the three power transmission shafts 19 on the shaft plate into the gap between the fan blades respectively.

[0031] 2. Tighten the fixing screw 17 inward to press against the motor and fan housing to prevent the entire device from falling off during use;

[0032] 3. Turn the crank handle 18 to transmit power to the motor through the right-angle commutator 7 and open the furnace door.

[0033] It should be noted that the specific embodiments described above enable those skilled in the art to gain a more comprehensive understanding of this utility model, but do not limit this utility model in any way.
