Description

Technical Field

[0001] The utility model relates to the technical field of gantry cranes, and more specifically, to a self-lubricating gantry crane. Background Art

[0002] Gantry crane is a kind of deformation of bridge crane, also called gantry crane. It is mainly used for loading and unloading of outdoor cargo yard, material yard cargo and bulk cargo. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and is widely used in port cargo yards.

[0003] However, most gantry cranes in the prior art are used outdoors and are easily affected by rain. Once rain falls on the surface of the machine for a long time, the displacement mechanism of the machine will rust, affecting the transportation efficiency of the crane. Manual maintenance is required regularly, which is time-consuming and labor-intensive and affects work efficiency.

[0004] In addition, the remaining amount of lubricating oil cannot be observed clearly and directly, and manual inspection of the remaining amount is required for a long time. When the lubricating oil is insufficient, it is added, which consumes energy and fails to add the lubricating oil in time, resulting in reduced lubrication efficiency between structures. Utility Model Content

Once rain falls on the surface of the machine for a long time, the displacement mechanism of the machine will rust, affecting the transportation efficiency of the crane, requiring manual shutdown and maintenance on a regular basis, which is time-consuming and labor-intensive and affects work efficiency.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions:

[0007] A self-lubricating gantry crane comprises a crane main beam, a lateral displacement mechanism is arranged on the crane main beam, a plurality of tooth blocks are fixedly connected at equal intervals in an embedding groove above the crane main beam, the lateral displacement mechanism comprises a housing slidably connected to the crane main beam, two gears are rotatably connected to the inner side of the lower side of the housing, and both of the two gears are meshed with the tooth blocks;

[0008] An oil storage cavity is opened inside the upper part of the shell, an oil filling pipe is fixedly connected to the upper side of the shell, a pump body is fixedly installed on one side of the shell, an output end of the pump body is fixedly connected to an oil injection pipe, the other end of the oil injection pipe is arranged corresponding to the position of the gear block, the pump body is started at a fixed time to extract the lubricating oil, and the lubricating oil is sprayed to the gear block through the oil injection pipe. When the gear contacts the gear block again, the gear and the gear block can be lubricated, thereby realizing self-lubrication of the gantry crane, thereby reducing long-term friction between structures and extending the service life.

[0009] As a preferred solution of the utility model, a metering cylinder is fixedly connected to the other upper side of the housing, and a warning light is fixedly installed on the upper side of the metering cylinder.

[0011] An elastic switch is fixedly installed below the outer wall of the metering cylinder. The elastic switch is electrically connected to the prompt light, and a button of the elastic switch extends to the inside of the metering cylinder.

[0012] As a preferred solution of the utility model, two guide rods are fixedly connected inside the oil storage cavity, and the two guide rods are respectively slidably connected to one side of the floating block.

[0017] (1) A cable and a hook are provided on the other side of the lateral displacement mechanism. The gears are meshed with the tooth blocks so that the lateral displacement mechanism can lift objects and transport them horizontally along the crane main beam. The oil storage cavity above the outer shell is used to store lubricating oil. The lubricating oil can be added to the oil storage cavity through the oil filling pipe. The pump body can use a timing pump so that the pump body starts at a fixed time to extract the lubricating oil. The lubricating oil is sprayed to the tooth block through the oil injection pipe. When the gear contacts the tooth block again, the gear and the tooth block can be lubricated, thereby realizing the self-lubrication of the gantry crane, thereby reducing the long-term friction between the structures and extending the service life.

[0018] (2) In order to observe the lubricating oil reserves in real time, the floating block can float up and down according to the liquid level of the lubricating oil in the oil storage cavity. Since the touch block and the floating block are fixedly connected by an extension rod, the touch block can move up and down synchronously with the floating block.

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] For details, please refer to Figure 1 and Figure 3 A self-lubricating gantry crane comprises a crane main beam 1, on which a lateral displacement mechanism 2 is arranged, a plurality of tooth blocks 3 are fixedly connected at equal intervals in an embedding groove above the crane main beam 1, the lateral displacement mechanism 2 comprises a shell 201 slidably connected to the crane main beam 1, two gears 202 are rotatably connected to the inner side of the lower side of the shell 201, both gears 202 are meshed and connected to the tooth blocks 3, an oil storage cavity 208 is opened inside the upper part of the shell 201, an oil filling pipe 209 is fixedly connected to one side of the upper side of the shell 201, a pump body 5 is fixedly installed on one side of the shell 201, an oil injection pipe 6 is fixedly connected to the output end of the pump body 5, and the other end of the oil injection pipe 6 is arranged at a position corresponding to the tooth block 3.

[0030] In a further embodiment, a cable and a hook are provided on the other side of the lateral displacement mechanism 2. The gear 202 is meshed with the tooth block 3 so that the lateral displacement mechanism 2 can lift objects and transport them laterally along the crane main beam 1. The internal oil storage cavity 208 above the outer shell 201 is used to store lubricating oil. The lubricating oil can be added to the oil storage cavity 208 through the oil filling pipe 209. The pump body 5 can use a timing pump so that the pump body 5 starts at a fixed time to extract the lubricating oil. The lubricating oil is sprayed to the tooth block 3 through the oil injection pipe 6. When the gear 202 contacts the tooth block 3 again, the gear 202 and the tooth block 3 can be lubricated, thereby realizing self-lubrication of the gantry crane, thereby reducing long-term friction between structures and extending the service life.

[0031] For details, please refer to Figure 1 , Figure 3 and Figure 4 A metering cylinder 210 is fixedly connected to the other side of the upper part of the shell 201, and a warning light 211 is fixedly installed above the metering cylinder 210. A floating block 212 is provided in the oil storage cavity 208, and an extension rod 213 is fixedly connected above the floating block 212. The other end of the extension rod 213 extends to the interior of the metering cylinder 210 and is fixedly connected to a touch block 215. An elastic switch 7 is fixedly installed at the lower part of the outer wall of the metering cylinder 210. The elastic switch 7 is electrically connected to the warning light 211, and the button of the elastic switch 7 extends to the interior of the metering cylinder 210.

[0032] In a further embodiment, in order to observe the reserves of lubricating oil in real time, the floating block 212 can float up and down according to the liquid level position of the lubricating oil in the oil storage cavity 208. Since the touch block 215 and the floating block 212 are fixedly connected by the extension rod 213, the touch block 215 can be moved up and down synchronously with the floating block 212. When the floating block 212 touches the bottom, the touch block 215 is simultaneously moved to the inner bottom surface of the metering cylinder 210, and the touch block 215 can squeeze the button of the elastic switch 7. Once the elastic switch 7 is triggered, the prompt light 211 will light up red synchronously, so that the staff can observe the reserves of lubricating oil in real time from the outside to ensure the self-lubricating efficiency of the gantry crane.

[0033] For details, please refer to Figure 3 Two guide rods 214 are fixedly connected to the inside of the oil storage cavity 208 , and the two guide rods 214 are slidably connected to one side of the floating block 212 respectively.

[0034] In a further embodiment, the floating block 212 is limited by the guide rod 214 , and the floating block 212 slides along the guide rod 214 , thereby improving the floating stability of the floating block 212 .

[0035] For details, please refer to Figure 1 and Figure 2 A driving shaft 203 is fixedly connected to the axis center of one gear 202, a servo motor 4 is fixedly installed on one side of the housing 201, and the output end of the servo motor 4 is coaxially fixedly connected to the driving shaft 203. A driven shaft 205 is fixedly connected to the axis center of another gear 202, and the other end of the driven shaft 205 is fixedly connected to a driven wheel 206, and the other end of the driving shaft 203 is fixedly connected to a driving wheel 204, and a transmission belt 207 is sleeved between the driving wheel 204 and the driven wheel 206.

[0036] In a further embodiment, the servo motor 4 can drive the driving shaft 203 to rotate, and the driving shaft 203 rotates while driving the corresponding gear 202 to rotate, so that the lateral displacement mechanism 2 is displaced through the cooperation between the gear 202 and the gear block 3;

[0037] In addition, when the driving shaft 203 rotates, the driving wheel 204 rotates synchronously. When the driving wheel 204 rotates, it drives the transmission belt 207 to rotate. The other end of the transmission belt 207 drives the driven wheel 206, the driven shaft 205 and another gear 202 to rotate, thereby achieving synchronous rotation of the two gears 202 and improving the movement efficiency of the lateral displacement mechanism 2.

[0038] Working principle:

[0039] When the utility model is used, the servo motor 4 is activated, and the two gears 202 are driven by the lateral displacement mechanism 2 along the meshing tooth block 3 to transport the objects horizontally along the crane main beam 1. The pump body 5 is started at a fixed time to extract the lubricating oil, and the lubricating oil is sprayed to the tooth block 3 through the oil injection pipe 6. When the gear 202 contacts the tooth block 3 again, the gear 202 and the tooth block 3 can be lubricated, thereby realizing the self-lubrication of the gantry crane, and the floating block 212 can be adjusted according to the liquid level of the lubricating oil in the oil storage cavity 208. The touch block 215 is fixedly connected to the floating block 212 by the extension rod 213, so that the touch block 215 can move up and down synchronously with the floating block 212. When the floating block 212 touches the bottom, the touch block 215 is simultaneously moved to the inner bottom surface of the metering cylinder 210, and the touch block 215 can squeeze the button of the elastic switch 7. Once the elastic switch 7 is triggered, the prompt light 211 will light up red synchronously, so that the staff can observe the reserves of lubricating oil in real time from the outside to ensure the self-lubricating efficiency of the gantry crane.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
