Detailed implementation mode
[0025] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present utility model.
[0026] Refer to Figures 1-5 , the present utility model provides a technical solution:
[0027] Embodiment:
[0028] As Figures 1-5 shown, a fireproof door core material curing and lifting device includes a frame 1 and a lifting frame 2 arranged on the frame 1. The lifting frame 2 can move vertically within the frame 1. The lifting frame 2 is provided with a lifting track 3 adapted to the rollers of the pouring trolley 4 and a first driving component for driving the pouring trolley 4 to move.
[0029] The lifting frame 2 is driven by a second driving component.
[0030] Among them, as Figure 2 shown, 1. The obstacle is the workbench 21 arranged in the production workshop; 2. There are two lifting devices respectively arranged on both sides of the workbench 21; The workbench 21 is provided with a transition track that is connected end to end with the lifting tracks 3 of the two lifting devices.
[0031] Working principle: After the core material is demolded, the pouring trolley 4 enters the lifting frame 2, and the second driving component drives the lifting frame 2 to move upward until the lifting frame 2 is flush with the workbench 21 (the lifting track 3 is connected end to end with the transition track).
[0032] After that, the first driving component on the lifting frame 2 drives the pouring trolley 4 to move towards the transition track 22 (if the transition track 22 is long, the subsequent pouring trolley 4 can continue to push the previous pouring trolley 4). When the pouring trolley 4 enters the lifting device on the other side of the workbench 21, the lifting device drives the pouring trolley to descend to the ground and then send it out.
[0033] The utility model realizes the automatic lifting and lowering of the pouring trolley 4 by setting a lifting device, without manual participation throughout the process, solves the potential safety hazards existing in manual lifting, and at the same time can improve the circulation efficiency of the pouring trolley 4.
[0034] Further, as Figure 4 and Figure 5 shown, the first driving assembly includes a first driving motor 5 arranged on the lifting frame 2, a friction wheel 6 is connected to the output shaft of the first driving motor 5, and the friction wheel 6 protrudes from the upper surface of the lifting rail 3;
[0035] A friction belt 7 is arranged at the bottom of the pouring trolley 4, and the friction belt 7 is adapted to the friction wheel 6.
[0036] The first driving motor 5 drives the friction wheel 6 to rotate. When the friction wheel 6 rotates, the pouring trolley 4 is driven to move towards the fixed rail through the friction belt 7. The way of the cooperation between the friction wheel 6 and the friction belt 7 can drive the pouring trolley 4 while ensuring the effective driving of the pouring trolley 4 and avoiding a rigid connection with the turntable, thus facilitating the pouring trolley 4 to leave the turntable.
[0037] Further, as Figure 1 shown, the second driving assembly includes driving wheels 8 arranged at the four corners of the bottom of the frame 1, driven wheels 9 arranged at the four corners of the top of the frame 1. The four driving wheels 8 are in transmission connection with a second driving motor 20 through transmission parts. The driving wheels 8 and the driven wheels 9 are connected by a transmission chain 10, and both ends of the transmission chain 10 are respectively connected to the upper and lower surfaces of the lifting frame 2.
[0038] The transmission parts include two driving shafts 11 (wherein, the driving shafts 11 are rotatably connected to the frame 1 through bearing seats and bearings). The two ends of the driving shafts 11 are coaxially fixed with the driving wheels 8, and the driving shafts 11 are connected to the second driving motor 20 through sprockets and chains.
[0039] The lifting frame 2 is slidably connected to the frame 1 through four vertically arranged guide rods 12, and both ends of the guide rods 12 are fixed to the frame 1 through mounting seats.
[0040] Among them, 1. The driven wheels 9 at the top of the frame 1 are rotatably arranged on the frame 1 through two driven shafts. 2. Both the driving wheels 8 and the driven wheels 9 are sprockets.
[0041] Lifting principle of the lifting frame 2: The second driving motor 20 drives the driving shafts 11 to rotate through chains and sprockets. When the driving shafts 11 rotate, the driving wheels 8 are driven to rotate. When the driving wheels 8 rotate, the driven wheels 9 are driven to rotate through the transmission chain 10. And since both ends of the transmission chain 10 are respectively connected to the upper and lower sides of the lifting frame 2, the lifting frame 2 is driven to move upward in this process. When the driving wheels 8 rotate in reverse, the lifting frame 2 moves downward.
[0042] With such a setting, a single motor can synchronously drive the four drive wheels 8 to rotate synchronously, thereby ensuring the stable lifting of the lifting frame 2.
[0043] Furthermore, as Figure 1 shown, a detection block 13 is provided on the lifting frame 2, and a first sensor 14 and a second sensor 15 are sequentially provided on the frame 1 from top to bottom. The lifting frame 2 corresponds to the first sensor 14 and the second sensor 15 before and after lifting respectively. The first sensor and the second sensor can be, but are not limited to, inductive or capacitive sensors, and the detection block is made of a metal material.
[0044] The provided first sensor 14 is used to detect whether the lifting frame 2 has risen in place, while the second sensor 15 is used to detect whether the lifting frame 2 has descended in place.
[0045] Furthermore, as Figure 1 shown, a telescopic bolt 16 is provided on the lifting frame 2, and a bolt seat 17 is provided on one side of the frame 1 corresponding to the bolt 16. When the detection block 13 corresponds to the second sensor 15, the bolt 16 is inserted into the bolt seat 17. Among them, the bolt 16 is connected to a cylinder or an electric telescopic rod. Among them, the bolt seat can be, but is not limited to, fixed on the workbench.
[0046] When the provided bolt 16 is inserted into the bolt seat 17, it can ensure that the lifting frame 2 has no displacement, thereby ensuring that the pouring trolley 4 can enter or leave the lifting frame 2 smoothly.
[0047] Furthermore, two proximity switches 18 are sequentially provided on the frame 1 from top to bottom, and a proximity block 19 is provided on the lifting frame 2. When the detection block 13 corresponds to the second sensor 15, the proximity switches 18 detect the proximity block 19. The two provided proximity switches 18 are used to control the second drive motor 20 to stop when the lifting frame 2 rises in place and descends in place.
[0048] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And the changes and alterations made by those skilled in the art that do not depart from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
