Description

Technical Field

[0001] This utility model relates to the field of vertical lifting machine technology, specifically a vertical lifting machine for asphalt concrete production. Background Technology

[0002] Asphalt concrete is a commonly used road paving material, mainly composed of asphalt and aggregate mixed in a certain proportion. The advantages of asphalt concrete include: convenient construction, good acoustic performance, skid resistance, and water resistance. It is widely used in highways, bridges, airports, parking lots, and other places. Specific design and mix proportions need to be adjusted according to actual traffic loads, climate conditions, and service life. A vertical lifting device for asphalt concrete is typically used in the production and construction process to lift asphalt concrete from the mixing equipment to the paver or other construction equipment. This device can improve work efficiency, ensure a continuous supply of materials, and ensure smooth construction. However, existing vertical lifting machines for asphalt concrete production still have certain shortcomings; for example:

[0003] The patent application CN202122021079.4, entitled "A Vertical Lifting Machine for Asphalt Concrete Production," includes a lifting machine body. A sound-insulating net with an open bottom is fitted onto the head of the lifting machine body. A fixing device is provided between the sound-insulating net and the lifting machine body to connect the net and the lifting machine body, reducing noise pollution in the area where workers are located. By using the fixing device to detachably connect the sound-insulating net and the lifting machine head, the sound-insulating net significantly attenuates the sound wave propagation during vertical lifting operation, thereby reducing noise pollution and enhancing worker protection. However, while this vertical lifting machine for asphalt concrete production can be used effectively, its lifting effect is poor when the amount of raw material to be lifted is small. The equipment has a simple structure, low flexibility of use, and cannot quantitatively lift raw materials. Moving the equipment is cumbersome, increasing the user's workload and frequently causing inconvenience. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical lifting machine for asphalt concrete production, in order to solve the problems mentioned in the background art, such as poor lifting effect, simple equipment structure, low flexibility of use, inability to quantitatively lift raw materials, and cumbersome equipment movement, which increase the labor burden of users and often trouble users.

The two second spur gears mesh with each other, and the two first spur gears mesh with each other on the inner and outer teeth of the annular double-sided rack, respectively. A fixing rod is fixedly installed at the center of the right wall of the housing.

[0007] As a preferred embodiment of this utility model, a torsion spring is fixedly installed on the outside of the fixed rod, a rotating rod is connected to the outside of the fixed rod by a bearing, and the other end of the torsion spring is fixedly installed on the inner wall of the rotating rod. A bucket is fixedly installed on the top surface of the rotating rod, and a pressure sensor is embedded and fixedly installed on the bottom surface of the bucket.

[0008] As a preferred embodiment of this utility model, the support frame, groove, annular double-sided rack, housing, transmission motor, transmission shaft, first spur gear, second spur gear, fixing rod, torsion spring, rotating rod, bucket, and pressure sensor are symmetrically arranged about the center of the support frame.

[0009] As a preferred technical solution of this utility model, the support frame, groove, annular double-sided rack, housing, transmission motor, transmission shaft, first spur gear and second spur gear are symmetrically arranged about the center of the base. An electric push rod is embedded and fixedly installed on the left side of the lower bottom surface of the base. The right end of the electric push rod is hinged to a first connecting rod. A sliding groove is opened on the left side of the base. A second connecting rod is arranged inside the sliding groove, and a groove is opened on the second connecting rod.

[0010] As a preferred technical solution of this utility model, the slots opened on the first connecting rod and the second connecting rod are hinged, and a roller is rotatably connected to the lower right side of the second connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This vertical hoist for asphalt concrete production weighs the raw materials added inside the bucket through a pressure sensor. When the weight of the raw materials reaches the set value of the pressure sensor, the transmission motor drives the two first spur gears to rotate. The meshing of the first spur gears with the ring double-sided rack drives the bucket to rise and dump the raw materials. The meshing of the two first spur gears with the ring double-sided rack makes the bucket rise more stable, and the torsion spring automatically resets the bucket during dumping. The equipment has a high degree of automation and reduces the labor burden of the user. Attached Figure Description

[0021] The drive shaft 7, the first spur gear 8, and the second spur gear 9 are arranged symmetrically about the center of the annular double-sided rack 4. The two second spur gears 9 mesh with each other, and the two first spur gears 8 mesh with the inner and outer teeth of the annular double-sided rack 4 respectively. A fixing rod 10 is fixedly installed at the center of the right wall of the housing 5.

[0022] A torsion spring 11 is fixedly installed on the outside of the fixed rod 10. A rotating rod 12 is connected to the outside of the fixed rod 10 by a bearing. The other end of the torsion spring 11 is fixedly installed on the inner wall of the rotating rod 12. A bucket 13 is fixedly installed on the top surface of the rotating rod 12. A pressure sensor 14 is embedded and fixedly installed on the bottom surface of the bucket 13.

[0023] The support frame 2, groove 3, annular double-sided rack 4, housing 5, drive motor 6, drive shaft 7, first spur gear 8, second spur gear 9, fixing rod 10, torsion spring 11, rotating rod 12, bucket 13 and pressure sensor 14 are arranged symmetrically about the center of the support frame 2.

[0024] The support frame 2, groove 3, annular double-sided rack 4, housing 5, transmission motor 6, transmission shaft 7, first spur gear 8 and second spur gear 9 are symmetrically arranged about the center of the base 1. An electric push rod 15 is embedded and fixedly installed on the left side of the lower bottom surface of the base 1. The right end of the electric push rod 15 is hinged to the first connecting rod 16. A sliding groove 17 is opened on the left side of the base 1. A second connecting rod 18 is arranged inside the sliding groove 17, and a groove is opened on the second connecting rod 18.

[0025] The first connecting rod 16 and the second connecting rod 18 are hinged by slots, and the lower right end of the second connecting rod 18 is rotatably connected to a roller 19. The second connecting rod 18 and the roller 19 are symmetrically arranged about the center of the slide groove 17.

Four fixing pins 20 are evenly threaded through the top surface of the base 1.

[0026] Working Principle: When using a vertical hoist for asphalt concrete production, the user first activates two electric push rods 15, which drive the first connecting rod 16 and the second connecting rod 18 to adjust their angles, causing the four rollers 19 to extend and push the equipment to the designated position. Then, the user rotates the fixing pin 20 to insert it into the ground and secure the equipment. Simultaneously, raw materials are added to the bucket 13, and the pressure sensor 14 detects this. When the weight of the added raw materials reaches the weight set by the pressure sensor 14, the drive motor 6 automatically starts, driving the drive shaft 7 to rotate. The rotation of the drive shaft 7 then drives the first connecting rod 16 to rotate the second connecting rod 18. The rotation of the first spur gear 8 and the second spur gear 9, through the meshing of the two second spur gears 9, simultaneously drives the two first spur gears 8 to rotate. The two first spur gears 8 mesh with the internal and external teeth of the annular double-sided rack 4, driving the bucket 13 to rise, making the rise of the bucket 13 more stable. When the bucket 13 reaches the highest point of the equipment, the weight of the material pressing down causes the bucket 13 to flip over, dumping the material. Then, the force of the torsion spring 11 returns the bucket 13 to its original position, thus completing a series of operations. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
