Description

Technical Field

[0001] The present application relates to a new energy battery replacement device for engineering vehicles, and specifically to a cantilever crane for replacing new energy batteries of engineering vehicles. Background Technique

[0002] With the progress of new energy industry technology, now many engineering vehicles also start to use new energy batteries as their power output sources. Engineering vehicles are usually used in engineering projects. Common engineering vehicles include mining trucks, earth-hauling trucks, etc. Using new energy batteries as the power output, engineering vehicles greatly reduce the consumption of petroleum fuels, reduce the emissions of polluting gases, and reduce environmental pollution.

[0003] After an engineering vehicle uses a new energy battery for a period of time, the battery power will gradually decrease with the extension of the use time. Therefore, when the power of the new energy battery on the engineering vehicle is low, the new energy battery needs to be charged. Since the new energy battery on the engineering vehicle is large in volume and long in charging time, the engineering vehicle usually adopts the method of replacing the new energy battery to supplement the power source. Due to the large volume and heavy weight of the battery, equipment such as tower cranes or overhead cranes are needed to replace the battery on the engineering vehicle. However, the traditional tower cranes or overhead cranes and other equipment are slow and inefficient in replacing new energy batteries, which affects the construction speed and efficiency of engineering vehicles.

Detailed Embodiments

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] An embodiment of the present application discloses a cantilever crane for replacing a new energy battery of an engineering vehicle.

[0036] Referring to Figure 1 and Figure 2 , the cantilever crane includes a track 11, a chassis 12, a chassis power mechanism 13, a base 14, a base power mechanism 15, a support mechanism 16, a hoisting frame 17, a lifting mechanism 18, a reciprocating mechanism 19, and a lifting mechanism 20.

[0037] Referring to Figure 1 , the track 11 is fixed to the ground, and the chassis 12 is arranged on the track 11. Specifically, a plurality of rollers 121 are arranged at the bottom of the chassis 12, and the rollers 121 are used to travel on the track 11. The chassis power mechanism 13 is installed and fixed at the bottom end of the chassis 12. The output end of the chassis power mechanism 13 is connected to the rollers 121 and is used to drive the rollers 121 to rotate. The chassis power mechanism 13 can adopt a combination of a chassis power component and a chassis transmission component. The chassis power component can adopt a motor, and the chassis transmission component can adopt a reducer. The output end of the chassis power component is key-connected to the input end of the chassis transmission component, and the output end of the chassis transmission component is connected to at least two rollers 121, so as to drive the rollers 121 to roll on the track 11.

[0038] The base 14 is rotatably connected to the upper end of the chassis 12. Specifically, the base 14 can be rotatably connected to the chassis 12 through a slewing bearing. The base power mechanism 15 is installed on the chassis 12 and the base 14, and the base power mechanism 15 is used to drive the base 14 to rotate on the chassis 12.

[0039] Referring to Figure 2 , the base power mechanism 15 includes a base power component 151, a rotating gear 152, and a rotating rack 153. The base power component 151 can adopt a combination of a motor and a reducer. The rotating gear 152 is key-connected to the output shaft of the base power component 151. The rotating rack 153 is installed and fixed on the side end of the base 14. The rotating rack 153 is a curved arc rack. The rotating gear 152 meshes with the rotating rack 153. Specifically, the rotating rack 153 can also be installed and fixed on the base 14 at intervals by a plurality of pin shafts to simulate a curved arc rack, and the rotating gear 152 meshes with the plurality of pin shafts. When in use, the rotation angle of the base 14 on the chassis 12 is small, usually within ±3 degrees.

[0040] Referring to Figure 1, the support mechanism 16 is fixedly installed on the chassis 12, and the support mechanism 16 is used to support the base 14. Specifically, the support mechanism 16 includes a plurality of support components, and the plurality of support components are evenly distributed in the circumferential direction along the rotation center axis of the base 14 and the chassis 12. The support component includes a support frame 161 and a support wheel 162. The bottom of the support frame 161 is fixedly installed on the top of the chassis 12, and the support wheel 162 is rotatably connected to the top of the support frame 161. The support wheel 162 is used to support the base 14, and the support wheel 162 is in rolling contact with the base 14. That is, when the base power mechanism 15 drives the base 14 to rotate on the chassis 12, the base 14 will drive the support wheel 162 to roll.

[0041] The lifting frame 17 is slidably connected to the base 14 in the vertical direction. Specifically, a chute is formed on the lifting frame 17, a pulley is installed on the base 14, the pulley is located in the chute, and a limiting plate is formed at the top of the chute on the lifting frame 17. The limiting plate can limit the pulley to prevent the pulley from slipping out of the chute.

[0042] Refer to Figure 1 , the lifting mechanism 18 is installed on the base 14 and the lifting frame 17. The lifting mechanism 18 includes two sets of lifting components. The two sets of lifting components are respectively located on both sides of the lifting frame 17. The two sets of lifting components jointly drive the lifting frame 17 to lift and lower on the base 14, and the two sets of lifting components move synchronously. The lifting component includes a hydraulic cylinder 181, a lifting frame 182, a lifting gear 183 and a synchronous belt 184. The hydraulic cylinder 181 is arranged in the vertical direction, and the cylinder body of the hydraulic cylinder 181 is fixed on the base 14. The lifting frame 182 is fixedly installed on the piston rod of the hydraulic cylinder 181. The lifting gear 183 is rotatably connected to the lifting frame 182. One end of the synchronous belt 184 is fixed on the base 14, and the other end of the synchronous belt 184 is fixed on the lifting frame 17, and the synchronous belt 184 is meshed with the lifting gear 183. When in use, the piston rod of the hydraulic cylinder 181 controls the lifting of the lifting gear 183 by telescoping, so as to drive the lifting frame 17 to lift and lower on the base 14 by using the meshing of the lifting gear 183 and the synchronous belt 184.

[0043] Refer to Figure 3, The reciprocating mechanism 19 is installed on the hoisting frame 17, and the reciprocating mechanism 19 is used to reciprocate on the hoisting frame 17. The reciprocating mechanism 19 includes a reciprocating frame 191, a reciprocating power assembly 192, a reciprocating gear 193, and a reciprocating rack 194. The reciprocating frame 191 is slidably connected to the hoisting frame 17 in the horizontal direction. The reciprocating power assembly 192 is fixedly installed on the hoisting frame 17, and the reciprocating power assembly 192 can adopt a combination of a motor and a reducer. The reciprocating gear 193 is key-connected to the output shaft of the reciprocating power assembly 192. The reciprocating rack 194 is horizontally and fixedly installed on the top of the reciprocating frame 191, and the reciprocating gear 193 meshes with the reciprocating rack 194. The reciprocating power assembly 192 drives the reciprocating gear 193 to rotate, and the reciprocating gear 193 drives the reciprocating rack 194 to move so that the reciprocating frame 191 reciprocates horizontally on the hoisting frame 17.

[0044] The hoisting mechanism 20 is fixedly installed on the reciprocating frame 191, and the hoisting mechanism 20 is used to hoist the discharged new energy battery and the fully charged new energy battery to be replaced on the engineering vehicle. The hoisting mechanism 20 can adopt existing hoisting equipment, such as common electric hoists, etc.

[0045] Furthermore, referring to Figure 1 , since the new energy battery is large in volume and heavy in weight, in order to reduce the risk of the tipping of the cantilever crane, the cantilever crane further includes an anti-tipping mechanism 21.

[0046] The anti-tipping mechanism 21 is provided in two groups, and the two groups of anti-tipping mechanisms 21 are respectively located on two opposite sides of the base 14 to reduce the risk of tipping of the base 14.

[0047] The anti-tipping mechanism 21 includes an anti-tipping plate 211, a connecting rod 212, and an anti-tipping wheel 213. The anti-tipping plate 211 can be fixedly installed on the ground or on the wall. The connecting rod 212 is arranged in the vertical direction, and the connecting rod 212 is fixedly connected to the base 14. The anti-tipping wheel 213 is rotatably connected to the bottom of the connecting rod 212 in the horizontal direction. Since the base 14 has a rotation angle of ±3 degrees on the chassis 12, there is a certain gap between the connecting rod 212 and the anti-tipping plate 211 so that when the base 14 rotates on the chassis 12, the connecting rod 212 will not be broken due to collision with the anti-tipping plate 211. The anti-tipping wheel 213 is located below the anti-tipping plate 211, and the anti-tipping wheel 213 can be in contact with the bottom end surface of the anti-tipping plate 211 or have a small gap.

[0048] Referring to Figure 4, when replacing the new energy battery on the engineering vehicle, in order to prevent the new energy battery and circuit structures from being rained on, a rain shelter 22 is provided at the side end of the cantilever crane. The rain shelter 22 is used to protect the new energy battery on the engineering vehicle from rain. During use, the new energy battery on the engineering vehicle is located directly below the rain shelter 22.

[0049] During the charging process of the new energy battery, in order to protect the new energy battery from rain and also facilitate the storage and charging of the new energy battery, a container 23 can be set up on the site. The container 23 is located on the side of the cantilever crane away from the engineering vehicle for replacing the new energy battery. The new energy battery is placed in the container 23 for charging, and the cantilever crane is also placed inside the container 23. When the engineering vehicle needs to replace the new energy battery, the cantilever crane hoists the fully charged new energy battery to replace the discharged new energy battery on the engineering vehicle.

[0050] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
