Description

Technical Field

[0001] The utility model relates to the technical field of traction equipment, in particular to a walkable rechargeable electric traction vehicle. Background Art

[0002] A walking rail tractor is an industrial tractor that can be driven on roads and on rails. It can switch driving modes according to different working conditions on roads and railways. With the advancement of science and technology, walking rail tractors have realized electric control, which reduces the workload of operators. Therefore, they are more and more widely used.

[0003] In the prior art, when a walking electric tractor is used, it is usually necessary to add lubricating oil to the driving wheel and the driving shaft in advance. Since the lubricating oil can form an oil film between the metal parts of the machine, reducing the direct contact between them, thereby reducing friction, this method not only reduces friction, but also helps to cool and clean the machine, and prevent rust.

[0004] However, the current walking electric tractor lacks a protective structure at the drive shaft when in use, which causes external wires, hair and other linear waste to easily get entangled outside the drive shaft during driving. As the drive shaft continues to rotate, it will get stuck in the bearing outside the drive shaft, which not only increases the resistance when the drive shaft rotates, but also greatly reduces the service life of the drive shaft and the bearing. In view of this, we propose a walking rechargeable electric tractor. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a walk-type rechargeable electric tractor to solve the technical problem that the current electric tractor drive shaft is severely worn due to the entry of linear debris.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a walking type rechargeable electric tractor, including a tractor body and a protection mechanism: the two wheel drive shafts on both sides of the tractor body are respectively connected to the two protection mechanisms, and a plurality of safety mechanisms are tightly welded in the two protection mechanisms;

[0007] The protection mechanism comprises a fixed cylinder, the outside of the fixed cylinder is rotatably connected with a plurality of protection plates through a plurality of sleeves and rotating rods, and a plurality of safety mechanisms are fixedly connected to the outside of the fixed cylinder.

[0008] Preferably, a plurality of first mounting grooves are formed outside the fixing tube, and a plurality of sleeves are tightly welded to the plurality of first mounting grooves respectively, and two sleeves are arranged in one first mounting groove.

[0009] Preferably, the rotating rod is fixedly connected to one side of the protective plate, there are several rotating rods, the rotating rod is located in the first mounting groove, and the two ends of the rotating rod are respectively sleeved in two sleeves in the same first mounting groove.

[0010] Preferably, the protective plate is arc-shaped, two coil springs are arranged outside the rotating rod, and two ends of the two coil springs are respectively fixedly connected to the rotating rod and the opposite side of the two sleeves.

[0011] Preferably, a plurality of second mounting grooves are formed outside the fixing tube, a plurality of safety mechanisms are respectively arranged in the plurality of second mounting grooves, and the other sides of the plurality of protection plates are fixedly connected with extension rods.

[0012] Preferably, the safety mechanism comprises a telescopic rod, a spring is connected to the outer shell of the telescopic rod, two ends of the spring are respectively fixedly connected to one end of the telescopic rod and the inner wall of the second mounting groove, and one end of the telescopic rod is fixedly connected to the inner wall of the second mounting groove.

[0013] Preferably, the other end of the telescopic rod is fixedly connected to an extrusion block, a rubber block is provided on one side of the extrusion block, and the other side of the extrusion block is fixedly connected to two counterweight blocks.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model improves the structure of the existing walk-type rechargeable electric tractor, so that during the movement of the tractor body, the fixed cylinder will rotate synchronously with the rotation of the wheels and the drive shaft of the tractor body. At this time, under the action of centrifugal force, the protective plate outside the fixed cylinder will gradually flip along the rotating rod and be in a relatively vertical position with the fixed cylinder. At this time, when linear debris is wrapped around the outside of the drive shaft, the protective plate will block it, so that the linear debris is wrapped around the outside of the unfolded protective plate, thereby avoiding the increase of friction at the drive shaft due to long-term use of the tractor body and the adhesion of linear impurities on the ground, avoiding the increase of resistance when the drive shaft rotates due to clogging of debris, and playing a role in ensuring the service life of the tractor.

[0016] 2. The utility model adds a plurality of safety mechanisms outside the fixed cylinder. When too much linear debris is entangled and not cleared, the protective plate cannot be flipped to the specified position when the fixed cylinder rotates due to the accumulation of debris. At this time, the extrusion block will pull the telescopic rod to extend under the action of centrifugal force, thereby pushing the protective plate to continue to flip to the specified position, thereby providing a safety effect for the flipping of the protective plate and improving the stability when using the tractor.

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0027] A pedestrian rechargeable electric tractor, see Figures 1 to 6 , including a tractor body 1 and a protection mechanism 2: the two wheel drive shafts on both sides of the tractor body 1 are respectively engaged with the two protection mechanisms 2, and a plurality of safety mechanisms 3 are tightly welded inside the two protection mechanisms 2;

[0028] The protection mechanism 2 includes a fixed cylinder 201, and the outside of the fixed cylinder 201 is rotatably connected to a plurality of protection plates 205 through a plurality of sleeves 203 and a rotating rod 204. The plurality of safety mechanisms 3 are fixedly connected to the outside of the fixed cylinder 201. The utility model improves the structure of the existing walkable rechargeable electric tractor, so that during the movement of the tractor body 1, the fixed cylinder 201 will rotate synchronously with the rotation of the wheels and the drive shaft of the tractor body 1. At this time, under the action of centrifugal force, the protection plate 205 outside the fixed cylinder 201 will gradually flip along the rotating rod 204 and be in a relatively vertical position with the fixed cylinder 201. At this time, when linear debris is wrapped around the outside of the drive shaft, the protection plate 205 will block it, so that the linear debris is wrapped around the outside of the unfolded protection plate 205, thereby avoiding the increase of friction at the drive shaft due to long-term use of the tractor body 1 and the adhesion of linear impurities on the ground, avoiding the increase of resistance when the drive shaft rotates due to clogging of debris, and playing a role in ensuring the service life of the tractor.

[0029] Specifically, a plurality of first mounting grooves 202 are opened outside the fixed tube 201, and a plurality of sleeves 203 are tightly welded in the plurality of first mounting grooves 202 respectively. Two sleeves 203 are arranged in the same first mounting groove 202. The setting of the first mounting groove 202 can ensure the flipping of the protective plate 205 and prevent it from colliding with the fixed tube 201.

[0030] Furthermore, the rotating rod 204 is fixedly connected to one side of the protective plate 205. There are several rotating rods 204. The rotating rod 204 is located in the first mounting groove 202. The two ends of the rotating rod 204 are respectively sleeved in two sleeves 203 in the same first mounting groove 202. By setting the rotating rod 204, the stable flipping of the protective plate 205 is guaranteed.

[0031] Furthermore, the protective plate 205 is arc-shaped, and two coil springs 206 are arranged outside the rotating rod 204, and the two ends of the two coil springs 206 are fixedly connected to the rotating rod 204 and the opposite side of the two sleeves 203 respectively. By adding an extension rod 208 on one side of the protective plate 205, the protective plate 205 can synchronously protect the inside of the wheel hub to prevent the entry of linear debris.

[0032] It is worth mentioning that a plurality of second mounting grooves 207 are provided outside the fixed cylinder 201, and a plurality of safety mechanisms 3 are respectively arranged in the plurality of second mounting grooves 207. The other sides of the plurality of protective plates 205 are fixedly connected with extension rods 208. The setting of the extension rods 208 can increase the weight of one side of the protective plate 205, thereby ensuring that the centrifugal force when the fixed cylinder 201 rotates is greater than the elastic force of the coil spring 206, and ensuring that the protective plate 205 can be stably flipped when the tractor moves.

[0033] It is worth noting that the safety mechanism 3 includes a telescopic rod 301, and a spring 302 is connected to the outer sleeve of the telescopic rod 301. The two ends of the spring 302 are respectively fixedly connected to one end of the telescopic rod 301 and the inner wall of the second mounting groove 207. One end of the telescopic rod 301 is fixedly connected to the inner wall of the second mounting groove 207. The utility model provides a plurality of safety mechanisms 3 outside the fixed cylinder 201. When too much linear debris is entangled and not cleaned up, the protective plate 205 cannot be flipped to the specified position when the fixed cylinder 201 rotates due to the accumulation of debris. At this time, the extrusion block 303 will pull the telescopic rod 301 to extend under the action of centrifugal force, thereby pushing the protective plate 205 to continue to flip to the specified position, thereby providing a safety effect for the flipping of the protective plate 205, and improving the stability when the tractor is used.

[0034] It is worth mentioning that the other end of the telescopic rod 301 is fixedly connected to the extrusion block 303, a rubber block 305 is provided on one side of the extrusion block 303, and the other side of the extrusion block 303 is fixedly connected to two counterweight blocks 304. Due to the provision of the counterweight blocks 304, the weight of the extrusion block 303 is increased, ensuring the centrifugal force of the extrusion block 303 when the fixed cylinder 201 rotates, ensuring that the extrusion block 303 has sufficient thrust.

[0035] Working principle: When in use, the tractor body 1 needs to be moved to the designated position, and the tractor is connected to the vehicle or shelf to be moved through the external hook to carry out traction transfer;

[0036] During the movement of the tractor body 1, the fixed cylinder 201 will rotate synchronously with the rotation of the wheels and the drive shaft of the tractor body 1. At this time, under the action of centrifugal force, the protective plate 205 outside the fixed cylinder 201 will gradually turn along the rotating rod 204 and be in a relatively vertical position with the fixed cylinder 201. At this time, when there are linear debris wrapped around the outside of the drive shaft, the protective plate 205 will block it, so that the linear debris is wrapped around the outside of the unfolded protective plate 205;

[0037] When too many linear debris are entangled and not cleaned up, the protective plate 205 cannot be turned over to the designated position when the fixed cylinder 201 rotates due to the accumulation of debris. At this time, the squeezing block 303 will pull the telescopic rod 301 to extend under the action of centrifugal force, thereby pushing the protective plate 205 to continue to turn over to the designated position;

[0038] After the tractor is used and stops moving, the protective plate 205 and the extrusion block 303 will gradually return to their original positions under the action of the coil spring 206 and the elastic force of the spring 302 due to the reduction of centrifugal force, and the linear debris can be cleaned at this time.

[0039] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
