Description

Technical Field

[0001] The invention relates to the technical field of pneumatic monorail cranes, in particular to a pneumatic monorail crane assembly. Background Art

[0002] Pneumatic monorail crane is a kind of suspension lifting equipment that uses compressed air as a power source. Its working principle is to use the energy of compressed air to drive the spreader or crane to complete tasks such as lifting, moving and unloading materials.

[0003] The main working parts of the pneumatic monorail crane include a compressed air source, a pneumatic drive, a monorail crane operating system and a hoist. When the pneumatic drive receives a command signal, it will control the flow of compressed air through a control valve, thereby creating a push-pull effect, allowing the hoist to perform operations such as lifting, moving and unloading. The pneumatic monorail crane can roll along the vertical surface of the hanging rail and move horizontally, turn, and pitch up and down with the track. The pneumatic monorail crane is widely used in multiple industries, especially in underground coal mining and equipment transportation. It plays an important role. It can also be used in other underground locations that require short-distance transportation. In addition, it is used in chemical industry, machinery manufacturing, large warehouses and logistics distribution centers.

[0004] Pneumatic monorail crane has the following main features: high safety: due to the use of compressed air as the power source, the pneumatic monorail crane will not generate electric sparks during operation, which is especially important in flammable and explosive environments, and solves the explosion-proof problem of lifting and transportation equipment; simple structure: compared with electric or diesel-driven equipment, the structural design of the pneumatic monorail crane is simpler, daily operation is more convenient, and the cost of maintenance and repair is also reduced; small size and light weight: the weight of the pneumatic monorail crane is only 1 / 3 to 1 / 8 of similar load-bearing capacity equipment, which is easy to install and move in narrow or confined spaces, improving the space utilization of the tunnel section.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1: This embodiment is intended to promote the solution of the existing pneumatic monorail crane, which usually compresses air and injects it into a gas tank to provide a compressed air source. However, the gas tank is generally installed on the ground, and the gas tank is connected to the pneumatic motor through a pipeline. The overly long pipeline is prone to entanglement and dragging, thereby easily affecting the flexibility and convenience of the pneumatic monorail crane. Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 A pneumatic monorail hanging assembly includes a track 100 and a reduction motor 110. A first driving wheel 120 and a second driving wheel 130 driven by the reduction motor 110 are arranged outside the reduction motor 110. A third driving wheel 140 and a fourth driving wheel 150 are also arranged outside the reduction motor 110. The first driving wheel 120, the second driving wheel 130, the third driving wheel 140 and the fourth driving wheel 150 travel along the track 100 at the same time.

[0038] A fixing assembly 160 for fixing goods is also provided on the side of the track 100. The number of the fixing assemblies 160 is set to be several. The fixing assemblies 160 include a connector 161 provided on the side of the track 100, a rotating wheel 162 rotatably provided at the end of the connector 161, and a hanging ring 163 fixedly installed in the middle of the connector 161; the connector 161 is set in a "U" shape, and the two ends of the connector 161 are provided with a rotating wheel 162, and the hanging ring 163 is used to hang and fix the goods; a shell 170 is provided on the outside of the reduction motor 110, and the first driving wheel 120, the second driving wheel 130, the third driving wheel 140 and the fourth driving wheel 150 are all rotatably provided on the upper side of the shell 170, and a rope 171 is installed on the outside of the shell 170, and the middle of the rope 171 is connected to one of the fixing assemblies 160, and adjacent fixing assemblies 160 are also connected by the rope 171.

[0039] A pneumatic motor 180 is installed on the outside of the reduction motor 110, and the pneumatic motor 180 is transmission-connected to the reduction motor 110. The pneumatic motor 180 serves as a power source to drive the reduction motor 110. The pneumatic motor 180 and the reduction motor 110 are both technical means well known to technicians in the field, and are not elaborated here. A main control valve 190 for controlling the circulation of compressed air is installed on the outside of the pneumatic motor 180. One side of the main control valve 190 is connected to the pneumatic motor 180. An air storage tank 200 is arranged on the outside of the main control valve 190. The air storage tank 200 is used to store and provide a compressed air source. A valve 210 is fixedly installed on the side of the air storage tank 200, and the other side of the main control valve 190 is connected to the valve 210.

[0040] The main control valve 190 includes a first valve core 191 and a second valve core 192. The first valve core 191 includes a first upper valve core 1911 and a first lower valve core 1912 which are slidably arranged. The second valve core 192 includes a second upper valve core 1921 and a second lower valve core 1922 which are slidably arranged. The first valve core 191 and the second valve core 192 have the same structure.

[0041] The main control valve 190 has a first air outlet 193 and a second air outlet 194 on its side. The first air outlet 193 is close to the first valve core 191, and the second air outlet 194 is close to the second valve core 192. Both the first air outlet 193 and the second air outlet 194 are connected to the pneumatic motor 180. The main control valve 190 also has an air inlet 195 on its side. The air inlet 195 is connected to the valve 210.

[0042] A first muffler 196 and a second muffler 197 are disposed outside the main control valve 190 . The first muffler 196 is communicated with the cavity where the first valve core 191 is located, and the second muffler 197 is communicated with the cavity where the second valve core 192 is located.

[0043] A filter 211 is provided inside the gas tank 200. The filter 211 is used to filter the air and remove impurities such as moisture and oil in the air, thereby improving the quality of the compressed air. The filter 211 is a technical means well known to technicians in this field and will not be described in detail here. A relief valve 212 is installed on the side of the gas tank 200. The relief valve 212 is used to maintain a stable pressure in the gas tank 200, thereby stabilizing the gas source pressure, ensuring the continuous stability of the output gas, and the stability of the gas pressure output. When the air pressure in the gas tank 200 is ≥0.8MPa, the compressed air is discharged through the relief valve 212 for pressure relief, thereby ensuring a stable system pressure and protecting the system components from damage as much as possible. A drain valve 213 is also installed on the side of the gas tank 200. The drain valve 213 is used to discharge impurities such as moisture filtered out of the air.

[0044] In this embodiment: the cargo is connected to the device through the fixing assembly 160, and the compressed air in the gas storage tank 200 enters the cavity of the main control valve 190 where the first valve core 191 is located through the valve 210 and the air inlet 195. At the same time, the first upper valve core 1911 is closed and the first lower valve core 1912 is opened, so that the air pressure at the air inlet 195 flows into the first air outlet 193 through the first lower valve core 1912, and then flows into the pneumatic motor 180, and flows back to the main control valve 190 through the pipeline in the pneumatic motor 180 and the second air outlet 194, and finally, it is discharged through the second muffler 197, so that the air flow completes the operation;

[0045] During this process, the compressed air flowing through the pneumatic motor 180 increases the power source for the pneumatic motor 180, so that the pneumatic motor 180 drives the output shaft of the reduction motor 110 to rotate forward, thereby causing the reduction motor 110 to drive the first driving wheel 120 and the second driving wheel 130 to rotate, and then through the cooperation of the third driving wheel 140 and the fourth driving wheel 150, the device drives the goods to be transported along the track 100;

[0046] Similarly: compressed air enters the cavity of the main control valve 190 where the second valve core 192 is located, the second upper valve core 1921 is closed, and the second lower valve core 1922 is opened, and the air pressure flows through the second lower valve core 1922, the second air outlet 194, the pneumatic motor 180, the first air outlet 193 in sequence and flows back to the main control valve 190, and finally, is discharged through the first muffler 196, so that the pneumatic motor 180 drives the output shaft of the reduction motor 110 to reverse. In summary, the device can transport goods back and forth, thereby improving the flexibility and convenience of the pneumatic monorail crane, and solving the problem as much as possible in the existing pneumatic monorail crane, that air is usually compressed and injected into a gas tank, and a compressed air source is provided by a gas tank. However, the gas tank is generally installed on the ground, and the gas tank is connected to the pneumatic motor through a pipe. An excessively long pipe is prone to entanglement and dragging, which easily affects the flexibility and convenience of the pneumatic monorail crane.

[0047] It should be noted that: by setting the first valve core 191 and the second valve core 192, two air flow paths are realized, so as to independently control the forward and reverse rotation of the pneumatic motor 180, and by controlling the opening and closing degree of the first upper valve core 1911 and the first lower valve core 1912 in the first valve core 191, the size of the air source, the air output, and the balance air volume can be effectively adjusted, so that the main control valve 190 can operate normally under a low pressure of 0.2MPa; the air is discharged through the first muffler 196 and the second muffler 197 respectively, which can reduce the noise of the equipment during operation.

[0048] Embodiment 2: This embodiment is intended to promote the solution of the problem that the compressed air stored in the air storage tank 200 is limited, and it is difficult to provide sufficient compressed air steadily and continuously, which easily causes insufficient power, thereby easily affecting the practicality and convenience of the device.

[0051] In this embodiment: the rotating plate 243 rotates, and through the cooperation of the first connecting rod 241 and the second connecting rod 242, the piston 240 is pulled backward, so that the outside air enters the cylinder 230 through the third one-way valve 232, and then the piston 240 is pushed forward and reset, so that the air in the cylinder 230 enters the air inlet chamber 222 through the second one-way valve 231, and the above operation is repeated, so that the air pressure in the air inlet chamber 222 is continuously increased. At the same time, the air in the air storage chamber 221 is continuously discharged and used, so that the air pressure in the air storage chamber 221 is reduced, thereby increasing the air pressure difference between the air storage chamber 221 and the air inlet chamber 222, so that the compressed air in the air inlet chamber 222 enters the air storage chamber 221 through the first one-way valve 223, so that the air storage tank 200 can stably and continuously provide sufficient compressed air, provide sufficient power for the device as much as possible, thereby further improving the practicality and convenience of the device.

[0052] It should be noted that: the engagement between the third gear 252 and the fourth gear 260 drives the rotating shaft 261 to rotate, so that the rotating shaft 261 drives the rotating plate 243 to rotate.
