[0001] The utility model belongs to the technical field of brick making equipment, in particular to a brick making line elevator. Background Art
[0002] In the brick production line, the pressed bricks are moved along the brick-out line to the curing site, that is, the pressed bricks are transferred from the brick-out line to the curing site. For unburned bricks, the curing site is usually a place with ground rails and curing brackets. The formed bricks are supported by pallets and transported as a whole. When they reach the end of the brick-out line, they need to be transferred to the curing brackets, and then the curing brackets are moved along the ground rails of the curing site. After the curing time is reached, the curing brackets are pushed out of the curing site, and the bricks are removed and packaged for shipment. In order to maximize the use of the curing space in the curing site, the curing brackets usually have multiple layers of space. The bricks in pallet units need to be placed layer by layer in the spaces of each layer of the curing bracket, and then taken out from each layer of space after the curing cycle is reached.
[0003] In the prior art, forklift equipment is usually used to perform the above operations. When the brick pallet is transferred to the end of the brick production line, the forklift moves to the end of the brick production line and lifts the pallet, and then transfers the brick pallet to the maintenance bracket one by one. This operation method has the disadvantage of low efficiency. With the rapid development of brick production line technology, the degree of automation of brick machine equipment operation is getting higher and higher, and the production efficiency of brick making is also increasing. At present, a lifting equipment that can adapt to high-speed brick production lines is needed, which needs to be developed and designed according to the needs. Utility Model Content

DETAILED DESCRIPTION
[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.
[0021] See also Figure 1 and Figure 2 The brick-making line elevator of the utility model comprises a support frame 1, a lifting frame 8 is arranged inside the support frame 1, and a lifting drive assembly for driving the lifting frame 8 to lift and move and a counterweight frame 3 for counterweighting during the lifting process are also installed on the support frame 1. Under the driving action of the lifting drive assembly, the lifting frame 8 is lifted and displaced in the vertical direction, and the counterweight frame 3 is lifted and displaced synchronously during the lifting and displacement of the lifting frame 8.
[0022] like Figure 1 and Figure 2 As shown in , the support frame 1 is in the shape of a rectangular parallelepiped as a whole, including a bottom frame located at the bottom and a rectangular top frame located at the top, and column profiles are installed between the four corners of the bottom frame and the top frame. In this embodiment, two upper and lower U-shaped reinforced protection connecting frames 2 are also installed between the two column profiles located at the rear of the support frame 1, and the ends of the strong protection connecting frames 2 are welded and fixed to the column profiles. The strong protection connecting frame 2 has two functions: one of which is to enhance the overall structural strength of the support frame 1, and the other is to provide a certain degree of protection at the rear to prevent personnel, other on-site machinery, etc. from approaching the internal action components (i.e., the lifting frame 8 and its auxiliary components) of the brick-making line elevator.
[0023] like Figure 4 As shown in FIG. 1 , the lifting frame 8 is an inverted U-shaped frame, comprising two opposite rectangular side frames, and a plurality of connecting beams are installed between the tops of the two rectangular side frames. The counterweight frame 3 is rectangular in shape.
[0024] The lifting drive assembly includes two groups of front and rear support bases 4 installed on the top of the support frame 1, a rear linkage shaft 5 is installed between the two rear support bases 4, and a front linkage shaft 7 is installed between the two front support bases 4. Sprocket sets are installed at both ends of the rear linkage shaft 5 and the front linkage shaft 7, and chains 6 are wound around the sprocket sets. One end of the chain 6 is connected to the lifting frame 8, and the other end is connected to the counterweight frame 3. When the lifting drive assembly drives the lifting frame 8 to rise, the counterweight frame 3 descends. Conversely, when the lifting drive assembly drives the lifting frame 8 to descend, the counterweight frame 3 rises. The main function of the counterweight frame 3 is to keep each chain 6 in a tensioned state.
[0025] The lifting drive machine (not shown in the figure) is also included to drive the rear linkage shaft 5 and the front linkage shaft 7 to rotate synchronously. Specifically, in this embodiment, driven sprockets are installed on the rear linkage shaft 5 and the front linkage shaft 7. The lifting drive machine is fixed on the top frame of the support frame 1, and the driving sprocket installed on the output shaft of the lifting drive machine is connected with the driven sprocket. In this way, when the lifting drive machine is running, it drives the rear linkage shaft 5 and the front linkage shaft 7 to rotate synchronously in the forward or reverse direction.
[0026] like Figure 3 As shown in , each support base 4 is welded and installed on the top frame of the support frame 1, specifically, it is installed and fixed at the four corners of the top frame. The sprocket group on each support base 4 includes three sprockets, namely, inner, middle and outer sprockets. The inner sprocket is installed and fixed at the end of the corresponding linkage shaft, and the central axis of the middle sprocket is lower than the central axis of the inner sprocket and the outer sprocket. Taking one of the chains 6 as an example, one end of the chain 6 is fixedly connected to the top corner position of the lifting frame 8, and the other end is fixedly connected to the top end of the counterweight frame 3 on this side. The middle part of the chain 6 bypasses the sprocket group on the support base 4. Specifically, the chain 6 bypasses from the top of the inner sprocket, from the bottom of the middle sprocket, and from the top of the outer sprocket. In order to facilitate the transmission connection of the chain 6, a vertical through hole can be set on the profile of the top frame of the support frame 1, and the chain 6 passes through the corresponding through hole.
[0027] In this embodiment, counterweight guide rollers 3-1 are installed at the front and rear of the counterweight frame 3 (two upper and lower counterweight guide rollers 3-1 are respectively provided at the front edge and the rear edge), the counterweight frame 3 is located between the column profiles on the same side of the support frame 1, and the counterweight guide rollers 3-1 roll and move along the inner side elevation of the column profile. In this way, during the lifting and displacement of the counterweight frame 3, the movement stability of the counterweight frame 3 is significantly improved due to the guiding effect of the front and rear counterweight guide rollers 3-1.
[0028] Furthermore, in order to prevent the counterweight guide roller 3-1 from shifting in the lateral direction and becoming separated from the column profile, a guide rail can be installed on the inner side of the column profile. Accordingly, the counterweight guide roller 3-1 is selected to be a type with a wheel groove in the middle, so that the guide rail falls into the wheel groove of the counterweight guide roller 3-1, which further ensures the stability of the counterweight frame 3 when it is lifted or shifted.
[0029] In this embodiment, frame guide rollers 8-1 are installed at the front and rear of both sides of the lifting frame 8 (that is, at the front edge and rear edge of the rectangular side frame of the lifting frame 8), and the frame guide rollers 8-1 roll and move along the outer vertical surface of the column profile. In this way, during the lifting and displacement process of the lifting frame 8, the movement stability of the lifting frame 8 is significantly improved due to the guiding effect of the front and rear frame guide rollers 8-1.
[0030] Furthermore, in order to prevent the frame guide roller 8-1 from shifting in the lateral direction and becoming separated from the column profile, a guide rail can be installed on the outside of the column profile. Accordingly, the frame guide roller 8-1 is selected to be a type with a wheel groove in the middle, so that the guide rail falls into the wheel groove of the frame guide roller 8-1, which further ensures the stability of the lifting frame 8 during lifting and shifting.
[0031] A transverse frame 9 and a transverse driving assembly 11 for driving the transverse frame 9 to move transversely are installed on the lifting frame 8, and a bracket 10 is installed at the front of the transverse frame 9. When the transverse driving assembly 11 drives the transverse frame 9 to move forward or backward in the transverse direction, the bracket 10 moves forward or backward accordingly, and the bracket 10 plays a role similar to the front fork of a forklift, and is used to lift and lower the brick blank pallet.
[0032] See also Figure 4 , we can see that:
[0033] The traverse drive assembly 11 includes two opposite support beams 11-1 installed on the inner side of the lifting frame 8 (that is, installed on the inner side of the rectangular side frame of the lifting frame 8), a rack 11-2 is installed on the support beam 11-1, a drive shaft 11-4 is installed on the traverse frame 9, and drive gears 11-3 meshing with the rack 11-2 are installed at both ends of the drive shaft 11-4, and a traverse drive motor (not shown in the figure) is also installed on the traverse frame 9. The traverse drive motor drives the drive shaft 11-4 to rotate forward or reverse, and accordingly drives the gear 11-3 to roll along the rack 11-2, so that the traverse frame 9 and its bracket 10 shift forward or backward.
[0034] like Figure 4 As shown in the figure, the transverse frame 9 is a flat rectangular frame, and two brackets 10 are provided on the left and right. The rear part of the bracket 10 extends to the bottom of the transverse frame 9 and is welded and fixed to the transverse frame 9 to ensure the structural strength. Furthermore, the two supporting beams 11-1 are both C-shaped steel with openings facing inward. Travel wheels are installed on the left and right edges of the transverse frame 9. The travel wheels are located in the grooves of the C-shaped steel of the supporting beam 11-1 on this side. In this way, the transverse frame 9 can be stably shifted forward and backward. When the brick tray acts on the bracket 10, the transverse frame 9 will not overturn.
[0035] How to run:
[0036] The brick-making line elevator is arranged at the end of the brick-discharging line, and is used to transfer the brick blank pallet moved to the end of the brick-discharging line to the curing bracket. The brick-making line elevator is also used to unload the brick blank pallet that has completed curing from the curing bracket to the brick blank packaging line; taking the application mode arranged at the end of the brick-discharging line as an example, the end of the brick-discharging line extends into the interior of the support frame 1. In the initial state, the lifting frame 8, the transverse frame 9 and the bracket 10 move to the low position, and the transverse frame 9 and the bracket 10 move to the rear. At this time, the bracket 10 is at the same height as the end of the brick-discharging line and the two brackets 10 are respectively located on the left and right sides of the brick-discharging line. When the pallet carrying the brick blank moves to the end of the brick-discharging line, the left and right edges of the brick blank pallet are respectively located above the two brackets 10, and then the lifting drive component drives the lifting frame 8 and its auxiliary components to rise, so that the brick blank pallet is lifted upward, and the lifting stops when it reaches a certain height, and then the transverse drive component 11 drives the transverse frame 9 and the bracket 10 to shift forward, so that the brick blank pallet is placed in one of the storage spaces of the curing bracket located behind the end of the brick-discharging line;
[0037] Afterwards, the lifting drive assembly drives the lifting frame 8 to descend, and at the same time the transverse drive assembly 11 drives the transverse frame 9 and the bracket 10 to shift backward. Finally, the lifting frame 8, the transverse frame 9 and the bracket 10 are reset to the initial state, and the next brick pallet is moved to the top of the bracket 10 again, and the above-mentioned action steps are repeated to transfer the brick pallet to another storage space of the curing bracket; usually, the brick pallets are placed one by one into the storage spaces of different heights on the curing bracket from top to bottom. When the brick pallets are unloaded from the curing bracket after curing, they can be operated one by one from bottom to top.
