Description

Technical Field

[0001] The utility model belongs to the technical field of brick machine equipment, and particularly relates to a lifting and mould changing ground chain device. Background Art

[0002] Unburned bricks refer to a new type of building material that uses fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. (one or more of the above raw materials) as the main raw materials without high-temperature calcination. It is often used in scenes such as building walls and floor paving. Unburned bricks are usually pressed and formed by brick machine equipment. Before pressing, the mixed blank is injected into the lower mold, and then the upper mold is pressed down and the molding mold is vibrated. After pressing and forming, the mold is demolded to form a brick blank. Since there are many different models of unburned brick products, the same set of brick machine equipment usually needs to be equipped with multiple molds. When selecting and producing unburned bricks, the original molding mold on the brick machine equipment is removed and another mold is installed on the brick machine equipment.

[0003] As can be seen from the above, brick production involves the operation of taking and placing brick molds. In the prior art, a variety of brick molds are usually placed on the ground in a special storage place for molds. When the molds need to be taken and placed, forklift equipment is usually used. Since brick molds are usually heavy, cranes and the like are also used in some scenarios. With the improvement of the automation level of brick machine equipment, the current brick machine equipment has a mold loading platform that can actively shift to the top of the mold by lateral movement, and perform automatic / semi-automatic mold change. However, auxiliary mold change facilities are also needed to receive the original mold and supply new molds, and to assist on-site staff in transferring brick molds. The aforementioned auxiliary facilities do not currently exist and need to be developed and designed in a targeted manner. Utility Model Content

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0020] See also Figure 1The lifting and changing mold ground chain device of the utility model comprises a supporting chassis 1, a fixed mold bracket capable of positioning the mold is provided at the front of the supporting chassis 1, and a lifting and changing mold bracket is also provided above the supporting chassis 1. Among them, the supporting chassis 1 is used to stably support the fixed mold bracket and the lifting and changing mold bracket, and is usually placed and fixed on the ground at the brick-making site. The fixed mold bracket is used to position and support the mold. The mold unloaded from the mold loading platform of the brick machine equipment falls on the fixed mold bracket. The new mold supplied to the brick machine equipment is also first shifted to the fixed mold bracket before being installed on the mold loading platform of the transfer equipment. The lifting and changing mold bracket is used to lift the mold. When the mold descends, the bottom of the mold falls on the fixed mold bracket. When the mold rises, it is separated from the fixed mold bracket and can be shifted along the length direction of the local chain device.

[0021] See also Figure 2 , we can see that:

[0022] The supporting frame 1 is a rectangular frame made by welding square steel profiles to ensure structural strength.

[0023] In this embodiment, the fixed mold bracket includes two front and rear door-shaped brackets 2, the bottom of the door-shaped bracket 2 is fixedly connected to the supporting base frame 1. In order to further improve the overall structural strength, a reinforcing triangle plate 13 is welded and installed between the respective columns of the two door-shaped brackets 2 and the supporting base frame 1.

[0024] A positioning cone block 12 is installed on the top of each of the two columns of the two door-shaped brackets 2. The function of the positioning cone block 12 is to position the mold. Conical positioning holes corresponding to the positions of the positioning cone blocks 12 are set at the four corners of the bottom of the mold. In this way, when the mold is unloaded from the mold loading platform of the brick machine equipment to the fixed mold bracket, each positioning cone block 12 is embedded in the conical positioning hole at the bottom of the mold. On the other hand, when the mold located on the lifting mold changing bracket moves to the rear and the lifting mold changing bracket controls the mold to descend, the mold has an accurate position on the top of the fixed mold bracket through the cooperation between each positioning cone block 12 and the positioning cone hole at the bottom of the mold, which helps the mold loading platform of the brick machine equipment to shift to the top of the mold and combine with the mold smoothly.

[0025] See also Figure 3 , we can see that:

[0026] The lifting mold changing bracket includes two opposite supporting side brackets 10 with forklift windows 10-1, and a connecting crossbeam 14 is provided between the supporting side brackets 10. As shown in the figure, there are two front and rear connecting crossbeams 14 between the supporting side brackets 10. There are two groups of front and rear forklift windows 10-1, and the distance between the front and rear forklift windows 10-1 on the same supporting side bracket 10 is equal to the distance between the front forks of a common forklift device. When taking and placing a mold on the lifting mold changing bracket, the front fork of the forklift device passes through the forklift window 10-1.

[0027] A segmented support beam 6 is installed on the top of the two support side brackets 10, and a chain 7 is installed on each segment of the segmented support beam 6. Figure 3 As shown in FIG. 1 , each segmented supporting beam 6 includes three segments, front, middle and rear, and the gaps between adjacent segments are aligned with the forklift window 10 - 1 below.

[0028] like Figure 3 As shown in the figure, another connecting beam 14 is installed between the rear ends of the two segmented supporting beams 6, and the fixed mold support is located between this connecting beam 14 and the connecting beam 14 arranged between the rear ends of the two supporting side supports 10, and the rear end of the connecting beam 14 located in the front contacts the front end of the gate-type support 2 located in the front, and the front end of the connecting beam 14 located in the rear contacts the rear end of the gate-type support 2 located in the rear, so that the lifting and mold changing support is restricted in its action mode: that is, the combination of the segmented supporting beams 6, the supporting side supports 10 and the chain 7 can only be lifted and displaced, but cannot be displaced forward and backward along the length direction of the local chain device.

[0029] In this embodiment, the segments of the segmented supporting cross beam 6 are square steel segments, sprockets are installed at both ends of the square steel segment, and the chain 7 is installed between the two sprockets, and the upper part of the chain 7 is located above the square steel segment, and the lower part of the chain 7 is located inside the square steel segment. In this way, each chain 7 can be flexibly rotated and displaced, and the bottom of the mold supported by the lifting mold changing bracket falls on the chain 7. In this way, when the mold is pulled, the mold can be displaced forward or backward along the length direction of the local chain device. The forward displacement usually corresponds to the unloading operation of the original mold, and the backward displacement usually corresponds to the operation of supplying a new mold to the brick machine equipment.

[0030] A front swing frame 8 is hingedly installed at the front lower part of the segmented supporting cross beam 6, a rear swing frame 11 is hingedly installed at the rear lower part, and a connecting rod 9 is installed between the middle parts of the front swing frame 8 and the rear swing frame 11, and also includes a push hydraulic cylinder 3 for pushing and pulling the bottom of the front swing frame 8 or the rear swing frame 11. The function of the connecting rod 9 is to make the front swing frame 8 and the rear swing frame 11 move in a linked manner. The front end of the connecting rod 9 is hingedly connected to the front swing frame 8, and the rear end is hingedly connected to the rear swing frame 11. When the push hydraulic cylinder 3 pushes and moves the bottom of the front swing frame 8 or the rear swing frame 11, the two swing frames move in a linked manner.

[0031] In this embodiment, a front axle seat 16 is installed at the front bottom of the segmented supporting beam 6, and a front rotating shaft 15 is installed at the top of the front swing frame 8, and the end of the front rotating shaft 15 is located in the front axle seat 16; a rear axle seat 18 is installed at the rear bottom of the segmented supporting beam 6, and a rear rotating shaft 17 is installed at the top of the rear swing frame 11, and the end of the rear rotating shaft 17 is located in the rear axle seat 18.

[0032] In this embodiment, front slide rails 5 are installed on both sides of the front of the support chassis 1, and rear slide rails 4 are installed on both sides of the rear, front rollers 19 are installed on both sides of the bottom of the front swing frame 8 and are located in the front slide rails 5, and rear rollers 20 are installed on both sides of the bottom of the rear swing frame 11 and are located in the rear slide rails 4. When the push hydraulic cylinder 3 pushes the two swing frames to move in linkage, the front rollers 19 move synchronously in the front slide rails 5 and the rear rollers 20 move synchronously in the rear slide rails 4, which improves the movement stability of the lifting and lowering mold changing bracket.

[0033] In this embodiment, the rear end of the cylinder body of the push hydraulic cylinder 3 is hingedly connected to the rear of the supporting frame 1, and the front end of the telescopic rod of the push hydraulic cylinder 3 is hingedly connected to the bottom middle of the rear swing frame 11, that is, the push hydraulic cylinder 3 directly provides a pushing and pulling action to the rear swing frame 11.

[0034] How to run:

[0035] (1) Mold unloading

[0036] The mold loading platform of the brick machine equipment is accurately shifted together with the mold to the top of the fixed mold bracket, and then the mold loading platform unloads the mold onto the fixed mold bracket and the positioning cone 12 is embedded in the positioning cone hole at the bottom of the mold, and then the mold loading platform is disconnected from the mold; then the hydraulic cylinder 3 is pushed to act, so that the lifting mold changing bracket lifts the mold, and at this time the mold is separated from the top of the fixed mold bracket, and then the mold can be pulled to move forward to the middle position on the lifting mold changing bracket, and at this time the mold can be taken off the local chain device by a forklift and transferred to the mold storage place;

[0037] (2) Mold loading

[0038] A forklift is used to take the mold out of the mold storage place and place it on the lifting mold changing bracket in the jacking state. Then the mold is pulled to shift backward along the length direction of the local chain device until it moves to the top of the fixed mold bracket. Then the hydraulic cylinder 3 is pushed to operate to make the lifting mold changing bracket lower the mold. The mold falls on the fixed mold bracket and the positioning cone 12 is embedded in the positioning conical hole at the bottom of the mold to correct the mold position. Then the mold loading platform of the brick machine equipment is shifted to the top of the mold and descends to combine with the mold. Then the mold loading platform is reset on the brick machine equipment, and then brick production can be carried out.
