Description

Technical Field

[0001] This invention relates to the field of environmentally friendly aerated concrete block production technology, and in particular to a safe transfer shuttle vehicle for environmentally friendly aerated concrete block production. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks, also known as (environmentally friendly) aerated bricks or (environmentally friendly) aerated blocks, are AAC blocks produced using a high-temperature autoclaving process. During the production of environmentally friendly AAC blocks, the brick blanks need to be transferred, thus requiring the use of shuttle vehicles to transport finished or semi-finished AAC blocks.

[0003] A shuttle bus typically consists of a shuttle track and a shuttle bus body positioned on the track. However, existing shuttle bus bodies are generally driven directly by a motor to rotate the wheels at the bottom of the bus, allowing the bus to move along the track. For example, Chinese Patent Publication No. CN219726679U discloses a shuttle bus for a combined autoclave and aerated concrete block / standard brick assembly. This driving method generally has two speed settings (low speed and high speed, with the high speed typically being 3-5 times faster than the low speed). When switching between low and high speed, the aerated concrete blocks on the shuttle bus are prone to positional deviations due to the sudden and significant change in the bus's acceleration. This is especially true for unpacked stacks of aerated concrete blocks, where the blocks on the upper layer facing away from the side where the bus's acceleration changes (the rear side of the upper layer when switching from low to high speed; the front side of the upper layer when switching from high to low speed) are more likely to fall off. In other words, accidents are prone to occur when switching between low and high speed.

[0004] To address this issue, we designed an environmentally friendly, safe transfer shuttle vehicle for aerated concrete block production. This vehicle solves the problem of sudden, large changes in acceleration by using continuous, small-amplitude speed changes. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention discloses a safe transfer shuttle vehicle for the production of environmentally friendly aerated concrete blocks.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An environmentally friendly aerated concrete block production safety transfer shuttle vehicle includes a mounting frame. The mounting frame has shuttle guide rails on both sides of its top surface arranged along its length, and a shuttle vehicle body capable of traveling along its length is provided above the two shuttle guide rails. The mounting frame is provided with a drive component for driving the shuttle vehicle body at a position below the shuttle vehicle body. The drive assembly includes a lifting seat that is vertically slidably connected to the mounting frame. The upper end of the lifting seat is correspondingly hinged to the lower end of the drive swing rod, and the upper end of the drive swing rod is correspondingly hinged to the shuttle vehicle body. The lifting platform is equipped with a drive motor for driving the drive lever to rotate around its lower end.

[0007] Preferably, a pin is fixedly connected to the lower end of the drive rocker arm, and a pin seat is provided at the upper end of the lifting seat for rotatable connection with the pin. The pin is driven to connect to the output shaft of the drive motor.

[0008] Preferably, two drive levers are symmetrically arranged front and rear, so that the two drive levers, the shuttle car body and the lifting seat form a parallelogram structure.

[0009] Preferably, the lifting seat is rotatably connected to a drive shaft arranged along the length of the ferry guide rail, and the drive shaft is connected to a pin shaft through a worm gear assembly; The drive shaft is driven and connected to the output shaft of the drive motor.

[0010] Preferably, the mounting bracket is provided with a vertical guide rod, and the upper end of the vertical guide rod slides through the lifting seat.

[0011] Preferably, a support spring is fitted onto the vertical guide rod at a position corresponding to the position below the lifting seat.

[0012] Preferably, the mounting bracket has upwardly extending limiting plates at both ends, and the limiting plates are provided with trigger switches at positions corresponding to the shuttle vehicle body, and the trigger switches are connected to the drive motor signal.

[0013] Preferably, the shuttle rail is a T-slot rail, and the shuttle rail is provided with wheel assemblies that match the T-slots of the shuttle rail.

[0014] Preferably, the wheel assembly includes an inverted T-shaped wheel frame, with main wheels rolled on the bottom surface of the T-shaped groove of the ferry guide rail at both ends of the wing portion of the T-shaped wheel frame, a sliding block slidably fitted on the belly of the T-shaped wheel frame along its axial direction, and a movable frame correspondingly hinged to the sliding block, and auxiliary wheels rolled on the top surface of the T-shaped groove of the ferry guide rail at both ends of the movable frame. The T-shaped wheel frame is rotatably connected to an adjusting screw, and the adjusting screw is threadedly engaged with a sliding block.

[0015] By employing the technical solution described above, the present invention has the following beneficial effects: 1. Due to the configuration of the drive components, the angle between the drive swing arm and the shuttle guide rail can be gradually increased from small to large when the drive motor drives the drive swing arm at a constant speed, until the angle between the drive swing arm and the shuttle guide rail reaches 90 degrees, and then gradually decreases again. This achieves the function of the shuttle vehicle's speed gradually increasing and then decreasing, solving the technical problem of large instantaneous changes in acceleration of the shuttle vehicle when shifting gears in the existing technology, and realizing the function of safely transferring environmentally friendly aerated concrete blocks.

[0018] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0019] Example 1, in conjunction with Appendix Figure 1-3 5. An environmentally friendly safe transfer shuttle vehicle for the production of aerated concrete blocks, including a mounting frame 1, with shuttle guide rails 2 arranged along its length on both sides of the top surface of the mounting frame 1, and a shuttle vehicle body 3 capable of traveling along its length is provided above the two shuttle guide rails 2; a drive component 4 for driving the shuttle vehicle body 3 is provided at the position of the mounting frame 1 below the shuttle vehicle body 3. Furthermore, the drive assembly 4 includes a lifting seat 41 vertically slidably connected to the mounting frame 1. If necessary, the mounting frame 1 is provided with a vertical guide rod 11, the upper end of which slides through the lifting seat 41. If necessary, the lifting seat 41 can also be connected to the mounting frame 1 via a sliding structure, for example, via a vertical slide rail pair, where the fixed part of the slide rail pair is correspondingly fixed to the mounting frame 1, and the sliding part of the slide rail pair is correspondingly fixed to the lifting seat 41. The lower end of a drive swing rod 42 is hinged to the upper end of the lifting seat 41, and the upper end of the drive swing rod 42 is correspondingly hinged to the shuttle car body 3. The lifting platform 41 is equipped with a drive motor (shown in the figure) for driving the drive lever 42 to rotate around its lower end.

[0020] Since the shuttle car body 3 needs to be moved from one end of the shuttle guide rail 2 to the other end of the shuttle guide rail 2 during use, in order to ensure that the shuttle car body 3 accelerates first and then decelerates in the middle of the shuttle guide rail 2, the position of the lifting seat 41 in the front and rear directions (the length direction of the shuttle guide rail 2) can be set in the middle of the shuttle guide rail 2; so that the position of the lower end of the drive swing rod 42 in the front and rear directions is set in the middle of the shuttle guide rail 2.

[0021] With this configuration, when the shuttle bus moves from one end of the shuttle rail 2 to the other end, the drive motor drives the drive lever 42 to rotate around its lower end. Under the influence of gravity, the shuttle bus 3 will not move upward. At this time, the lifting seat 41 descends, and the angle between the drive lever 42 and the horizontal plane gradually increases. According to the principle of trigonometric functions, since the rotational speed (angular velocity) of the drive lever 42 remains constant, the larger the angle between the drive lever 42 and the horizontal plane, the greater the speed of the upper end of the drive lever 42 on the horizontal plane, which in turn causes the shuttle bus 3 to accelerate. When the drive lever 42 moves to a vertical position, the speed of the shuttle bus 3 reaches its maximum. At this time, the shuttle bus 3 is located in the middle of the shuttle rail 2. According to the above principle, when the shuttle bus 3 moves from the middle of the shuttle rail 2 to the other end, the speed of the shuttle bus 3 gradually decreases until the shuttle bus 3 moves to the other end of the shuttle rail 2.

[0022] To prevent over-running of the drive motor (i.e., the drive motor remaining running even after the shuttle car body 3 has moved to the end of the shuttle guide rail 2, thus avoiding damage to the drive motor), the mounting bracket 1 has upward-extending limiting plates 13 at both ends. Each limiting plate 13 has a trigger switch 14 corresponding to the position of the shuttle car body 3, and the trigger switch 14 is connected to the drive motor signal. Referring to the attached diagram, when the drive motor is started via the operating switch 15, the shuttle car body 3 begins to move. After reaching the end of the shuttle guide rail 2, the shuttle car body 3 contacts the corresponding trigger switch 14, causing the drive motor to stop running. This prevents over-running of the drive motor.

[0023] As needed, a pin 43 is fixedly connected to the lower end of the drive lever 42, and a pin seat 44 is provided on the upper end of the lifting seat 41, which is rotatably connected to the pin 43; the pin 43 is driven to be connected to the output shaft of the drive motor.

[0024] Furthermore, to reduce the length of the drive lever 42, two drive levers 42 are symmetrically arranged at the front and rear, so that the two drive levers 42, the shuttle vehicle body 3, and the lifting seat 41 form a parallelogram structure. As needed, the upper ends of the two drive levers 42 are respectively hinged to the front and rear ends of the shuttle vehicle body 3.

[0025] Furthermore, the lifting seat 41 is rotatably connected to a drive shaft 45 arranged along the length of the shuttle guide rail 2, and the drive shaft 45 is connected to the pin shaft 43 via a worm gear assembly; the drive shaft 45 is driven by the output shaft of the drive motor. That is, the drive motor can drive the drive shaft 45 to rotate, which in turn drives the pin shaft 43 to rotate, and the pin shaft 43 drives the drive rocker arm 42 to rotate. Compared with only one drive rocker arm 42, setting two drive rocker arms 42 reduces the distance the upper end of the drive rocker arm 42 moves by the distance between the two drive rocker arms 42, thus allowing for a reduction in the length of the drive rocker arm 42.

[0026] Example 2: In the above example, when the shuttle vehicle body 3 is not in the middle of the shuttle guide rail 2, that is, when the drive swing arm 42 is not in a vertical state, the output shaft of the drive motor tends to rotate due to the gravity of the drive component 4 itself, which affects the service life of the drive motor. To solve this technical problem, this example makes further improvements. Combined with appendix Figure 1-3 5. An environmentally friendly aerated concrete block production safety transfer vehicle, based on Embodiment 1, has a support spring 12 fitted onto the vertical guide rod 11 at a position corresponding to the lower part of the lifting seat 41. This arrangement allows the support spring 12 to support the lifting seat 41, thereby offsetting or reducing the impact of the drive assembly 4's own weight on the drive motor.

[0027] As needed, a limiting structure is provided at the upper end of the vertical guide rod 11; specifically, when the lifting seat 41 cooperates with the limiting structure, the shuttle car body 3 is located at the end of the shuttle guide rail 2.

[0028] In Example 3, in Example 2 above, when the shuttle car body 3 moves without being loaded, the shuttle car body 3 may be at risk of derailment due to the elastic force of the support spring 12 (during the test, the elastic force of the support spring 12 was too large). To solve this technical problem, this example makes further improvements. Combined with appendix Figure 4 An environmentally friendly safe transfer shuttle vehicle for the production of aerated concrete blocks is provided. Based on the second embodiment, the shuttle guide rail 2 is a T-shaped groove track, and the shuttle vehicle body 3 is provided with a wheel assembly 31 that matches the T-shaped groove of the shuttle guide rail 2. In this way, the height of the wheel assembly 31 can be limited by the inner top wall of the T-shaped groove of the shuttle guide rail 2, so as to prevent the wheel assembly 31 from falling off the T-shaped groove of the shuttle guide rail 2.

[0029] Furthermore, the wheel assembly 31 includes an inverted T-shaped wheel frame 311. Both ends of the wing of the T-shaped wheel frame 311 are provided with main wheels 312 that are rolled on the bottom surface of the T-shaped groove of the shuttle guide rail 2. The belly of the T-shaped wheel frame 311 is slidably fitted with a sliding block 313 along its axial direction. The sliding block 313 is correspondingly hinged with a movable frame 314. Both ends of the movable frame 314 are provided with auxiliary wheels 315 that can be rolled on the top surface of the T-shaped groove of the shuttle guide rail 2. The T-shaped wheel frame 311 is rotatably connected to an adjusting screw 316, and the adjusting screw 316 is threadedly engaged with the sliding block 313.

[0030] This configuration allows the main wheels 312 to travel on the bottom surface of the T-shaped groove of the shuttle guide rail 2, enabling the shuttle vehicle body 3 to move. Furthermore, when unloaded, the auxiliary wheels 315 roll against the top wall of the T-shaped groove of the shuttle guide rail 2, thus preventing any jamming.

[0031] The adjustment screw 316 is set so that the height of the main wheel 312 and the auxiliary wheel 315 matches the height of the T-slot of the ferry guide rail 2. The hinged setting of the movable frame 314 allows the auxiliary wheel 315 to float up and down, preventing jamming due to installation and manufacturing tolerances.

[0032] The parts of this invention not described in detail are prior art. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to encompass all changes falling within the meaning and scope of equivalents within this invention.
