(one) solving the technical problems
Aiming at the defects of the prior art, the utility model discloses a furnace door lifting and pressing device, which is used for solving the problems that the furnace door sealing of the existing heat treatment furnace provided in the background art is realized by pressing the furnace door by using other external force of a cylinder, so that an air source is wasted, the heat loss is large and the heat dissipation is large. The sealing is loose or broken, and the maintenance is not good, and the replacement is not good, so that the whole system is scrapped, manpower and material resources are wasted, the sealing is not lost, and the working requirements of users cannot be met.
(II) technical scheme
In order to achieve the above purpose, the utility model is realized by the following technical scheme: an oven door lifting and pressing device, comprising: the lifting speed reducer comprises a lifting speed reducer, a transmission chain, a lifting compression crank, a furnace door riding wheel and a tensioning wheel, wherein the transmission chain is arranged at the lower end of the lifting speed reducer and is in transmission connection with a transmission wheel of the lifting speed reducer, and the furnace door is arranged at the lower end of the transmission chain.
Preferably, a lifting compression crank is arranged on the furnace door, and the furnace door is connected with the transmission chain through the lifting compression crank.
Preferably, guide wheels are arranged at two ends of the lifting compression crank through brackets.
Preferably, the lower end of the furnace door is provided with a furnace door riding wheel for supporting the furnace door.
Preferably, a tensioning wheel is arranged below one side of the furnace door riding wheel.
The utility model discloses a furnace door lifting and pressing device, which has the following beneficial effects:
1. this furnace gate promotes closing device, promote the speed reducer and drive the chain, the chain drives promotes and compresses tightly the crank, make the crank one end prop up the furnace gate and make the guide pulley, the furnace gate rises in place under the drive of promotion speed reducer, otherwise, promote the speed reducer and reverse, the furnace gate descends, after the bottom of furnace gate contacts the furnace gate riding wheel, promote on the furnace gate and compress tightly the crank and begin to rotate under the pulling of chain, the other head of crank makes the furnace gate inwards remove under the effect of location channel-section steel this moment, and then compress tightly sealedly, play thermal-insulated effect, thereby satisfy user's user demand.
2. The furnace door lifting and pressing device has the advantages that the structure is simple and practical, the defect of the sealing device of the traditional old furnace door is overcome, the structure is simple and practical, the production requirement of a user is met, the labor and materials of the user are saved, and the investment cost is reduced.
Drawings
Fig. 1 is a front view of the present utility model.
In the figure: 1. lifting a speed reducer; 2. a drive chain; 3. lifting the compression crank; 4. a furnace door; 5. furnace door riding wheels; 6. and a tension wheel.
Detailed Description
The embodiment of the utility model discloses a furnace door lifting and pressing device, which is shown in fig. 1 and comprises: the lifting speed reducer 1, the transmission chain 2, the lifting compression crank 3, the furnace door 4, the furnace door riding wheel 5 and the tensioning wheel 6, wherein the transmission chain 2 is arranged at the lower end of the lifting speed reducer 1, the transmission chain 2 is in transmission connection with a transmission wheel of the lifting speed reducer 1, and the furnace door 4 is arranged at the lower end of the transmission chain 2.
According to the illustration of fig. 1, a lifting and pressing crank 3 is arranged on the furnace door 4, the furnace door 4 is connected with the transmission chain 2 through the lifting and pressing crank 3, and the furnace door 4 can be pulled up or put down under the action of the lifting and pressing crank 3 through the rotation of the transmission chain 2.
According to the figure 1, the two ends of the lifting pressing crank 3 are respectively provided with guide wheels through the brackets, and the guide wheels can effectively support and guide the furnace door 4 in the process of pulling the furnace door by the transmission chain 2.
According to the view shown in fig. 1, the lower end of the furnace door 4 is provided with a furnace door supporting wheel 5 for supporting the furnace door 4, and the lower side of one side of the furnace door supporting wheel 5 is provided with a tensioning wheel 6, so that the furnace door 4 can be effectively supported when the furnace door 4 is placed down, and meanwhile, friction force can be reduced when the furnace door 4 is pushed to move inwards to compress and seal.
Working principle: the utility model discloses a furnace door lifting and pressing device, which is characterized in that when in operation, a lifting speed reducer 1 drives a transmission chain 2, the transmission chain 2 drives a lifting and pressing crank 3, one end of the lifting and pressing crank 3 props a furnace door 4 and serves as a guide wheel, the furnace door 4 is lifted in place under the driving of the lifting speed reducer 1, otherwise, the lifting speed reducer 1 is reversed, and the furnace door 4 is lowered;
