Description

Technical Field

[0001] The invention relates to the technical field of mechanical engineering, in particular to an underframe turntable used for aerial work. Background Art

[0002] Aerial work refers to work performed at a height where there is a possibility of falling from a height of 2 meters or more above the falling height reference plane. In many fields such as modern construction, electricity, and fire protection, the demand for aerial work is also growing. In order to ensure the safety of the platform vehicles of the workers and improve the work efficiency, various aerial work equipment is constantly developing and innovating. For example, in the field of construction, with the increasing number of high-rise buildings, for operations such as exterior wall construction, window installation and cleaning, aerial work platform vehicles are usually required to safely deliver workers to the location of the aerial work, and perform various operations such as construction, installation, maintenance, and cleaning on the platform. The chassis turntable is a key component in the aerial work platform vehicle, which enables the working platform of the platform vehicle to rotate freely in the horizontal direction, thereby covering a larger working area; the working platform can be more accurately aligned with the work point, especially in situations where precise operation is required, such as installing specific building components or performing fine maintenance work.

[0003] However, since the rotating parts of the base turntable will generate friction with the supporting parts during relative motion, and the continuous friction will cause wear between the parts and make the contact surface rough, thereby increasing the friction between the rotating parts, which will in turn affect the stability performance and service life of the turntable during rotation. Therefore, it is necessary to inject lubricating oil into the parts of the turntable to form an oil film on the contact surface to reduce direct contact between the parts, reduce wear, and extend the service life of the parts. At present, when the turntable is lubricated, the operator usually uses an oiler or an oil gun to inject lubricating oil into the lubrication points of the parts at predetermined time intervals. However, the current oiling of the turntable relies entirely on the operator to remember the predetermined time intervals for oiling, and there may be errors in the manual judgment of the time interval, and the oiling timing cannot be adjusted in time according to the actual operating conditions and wear degree of the turntable parts, resulting in the turntable not being processed in time when lubrication is needed, which increases the friction between the rotating parts, accelerates the wear of the parts, and reduces the service life of the equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the base turntable for aerial work, as the turntable continues to work, the friction between the friction ring and the rotating frame gradually increases, and the friction ring will rotate with the rotating frame, and then drive the sleeve rod and the top to move synchronously along the outer circumference of the oil storage barrel through the connecting frame, and the top rod will slide between the connecting block and the spiral groove, so that the connecting block drives the top rod to move upward along the inner wall of the sleeve rod through the traction of the spiral groove, and the top rod will push the clamping ring to rise synchronously when it rises, and the clamping ring will drive the baffle A to rise synchronously through the L-shaped rod A when it rises, and the baffle A will drive the baffle B to rise synchronously through the arc rod when it rises, and then expose the notch, so that the lubricating oil inside the oil storage barrel can be discharged from the connecting pipe B after passing through the connecting pipe A and the installation groove through the notch, so that the friction between the rotating parts is increased and then the oil filling and lubrication work between the turntable parts is automatically completed, thereby reducing the accelerated wear of the parts caused by the failure to fill the oil and lubricate in time, and eliminating the frequent manual inspection and oil filling operations, saving manpower and time costs.

[0016] 2. In the base frame turntable for aerial work, the protrusions at both ends of the clamping ring have a certain gap, so that the clamping ring will not contact the end of the L-shaped connecting rod B when the height changes within a certain range. When the friction between the rotating frame and the friction ring is large, the height that the top rod pushes the clamping ring to rise will have a higher upper limit, so that the clamping ring can drive the L-shaped connecting rod B to move upward. When the L-shaped connecting rod B rises, it will drive one of the push plates to rise synchronously, and then one of the racks will rise synchronously and then mesh with the gear, so that the gear rotates, and when the gear rotates, it will cause the other rack to move downward. The two racks synchronously drive the two sieve plates A to close at the opening of the connecting pipe B. While the two racks drive the sieve plates to close, the two connecting rods drive the two sieve plates B to separate in opposite directions through the connecting rod. Since the mesh number of sieve plate A is greater than the mesh number of sieve plate B, the displacement of the lubricating oil through the mounting groove is increased, and then the closing and separation of sieve plates A and B at the opening of the mounting groove are switched, thereby changing the displacement of the lubricating oil of the rotating parts during the oil filling operation, thereby avoiding the waste of lubricating oil caused by excessive oil filling and the unstable operation of the rotating parts caused by insufficient lubrication.

The output shaft of the driving motor 161 passes through the inside of the mounting seat 1 and is fixedly connected with a worm 162. One end of the worm 162 is rotatably connected to the inner side of the mounting seat 1, and the outer edge of the worm 162 meshes with the teeth of the gear ring 205; the inner side of the friction ring 204 is fixedly connected with a connecting frame 6, one end of the connecting frame 6 is fixedly connected with a sleeve rod 601, and the sleeve rod 601 is located on the inner wall of the connecting box 3, the inner wall of the sleeve rod 601 is slidably connected with a push rod 602, and the top of the push rod 602 is slidably connected to the bottom of the retaining ring 214; a spiral groove 7 is opened on the outer side of the oil storage barrel 208, and a connecting block 8 is slidably connected to the inner side of the spiral groove 7, and the end of the connecting block 8 is fitted with the rotating frame fixedly connected to the outer side of the push rod 602.

[0030] In this embodiment, the worm 162 is driven to rotate by starting the driving motor 161. When the worm 162 rotates, it meshes with the gear ring 205, so that the gear ring 205 drives the inner wall of the groove A of the rotating frame 203 to rotate. When the lubricating oil between the grooves A of the rotating frame 203 is gradually consumed as the turntable continues to work, the friction between the friction ring 204 and the rotating frame 203 will gradually increase, and then the friction ring 204 will rotate together with the rotation of the rotating frame 203. While the friction ring 204 rotates, it will drive the sleeve rod 601 and the top to move synchronously along the outer periphery of the oil storage barrel 208 through the connecting frame 6. While the push rod 602 moves, it will slide between the connecting block 8 and the spiral groove 7, so that the connecting block 8 drives the push rod 602 to move upward along the inner wall of the sleeve rod 601 through the traction of the spiral groove 7, and the push rod 602 will push the card when it rises. The ring 214 rises synchronously, and due to the sliding between the top of the push rod 602 and the lower surface of the retaining ring 214, the retaining ring 214 can only move vertically up and down, and will not rotate with the movement of the push rod 602. While rising, the retaining ring 214 will drive the baffle A211 to rise synchronously through the L-shaped rod A, and while the baffle A211 rises, it will drive the baffle B213 to rise synchronously through the arc rod 212, and then expose the slot 210, so that the lubricating oil inside the oil storage barrel 208 can be discharged from the connecting pipe B901 through the slot 210 after passing through the connecting pipe A9 and the mounting groove 301, and then the oiling work is carried out, so that the turntable can automatically complete the oiling and lubrication work between the turntable parts through the increase of the friction between the rotating parts, reduce the accelerated wear of the parts caused by the failure to timely oiling and lubrication, and avoid frequent manual inspection and oiling operations, saving manpower and time costs.

[0031] In this embodiment, Figure 6 , Figure 7 , Fig. 9 and Fig.10As shown, a connection box 3 is fixedly installed on the top of the oil storage barrel 208, and a mounting groove 301 is opened on the inner wall of the connection box 3. An adjustment component 4 is arranged inside the mounting groove 301. The adjustment component 4 includes two mounting plates 401, and the two mounting plates 401 are fixedly connected to the outer wall of the connection box 3, and two push plates 402 are symmetrically fitted between the two mounting plates 401, and the outer sides of the two push plates 402 are fitted with the inner side of the mounting groove 301, and a bracket 403 is fixedly connected to the inner wall of the mounting groove 301, and a gear 404 is rotatably connected to the inner wall of the bracket 403, and the outer edge of the gear 404 is meshed with two racks 405, and one end of the two racks 405 is fixed It is connected to a sieve plate A406, and the outer walls of the two sieve plates A406 are slidably connected to the inner wall of the mounting plate 401, the other ends of the two racks 405 are fixedly connected to a connecting rod 407, the ends of the two connecting rods 407 are fixedly connected to a connecting rod 408, and one end of the two connecting rods 408 is fixedly connected to a sieve plate B409, and the outer walls of the sieve plate B409 are slidably connected to the inner wall of the mounting plate 401; the lower surface of one of the push plates 402 is fixedly connected to an L-shaped connecting rod B5, the outer wall of the L-shaped connecting rod B5 is slidably connected to the inner wall of the mounting groove 301, and one end of the L-shaped connecting rod B5 is located in the middle position of the protrusions on both sides of the retaining ring 214.

[0032] In this embodiment, there is a certain gap between the protrusions at both ends of the snap ring 214, so that the snap ring 214 will not contact the end of the L-shaped connecting rod B5 when the height changes within a certain range. When the friction between the rotating frame 203 and the friction ring 204 is small, the force of the friction ring 204 during rotation will be small, and then the upper limit of the height of the snap ring 214 is low, so that it cannot contact the end of the L-shaped connecting rod B5. When the friction between the rotating frame 203 and the friction ring 204 is large, the upper limit of the height of the snap ring 214 pushed by the top rod 602 is high, so that the snap ring 214 can drive the L-shaped connecting rod B5 to move upward synchronously, and the L-shaped connecting rod B5 will drive one of the push plates 402 to rise synchronously while rising, and then one of the racks 405 will rise synchronously and then meet the gear 4 04 meshes, causing the gear 404 to rotate, and while the gear 404 rotates, the other rack 405 will descend, so that the two racks 405 synchronously drive the two sieve plates A406 to close at the opening of the connecting pipe B901, and while the two racks 405 drive the sieve plates to close, the two connecting rods 408 drive the two sieve plates B409 to separate in opposite directions through the connecting rod 407, and since the mesh number of the sieve plate A406 is greater than the mesh number of the sieve plate B409, the displacement of the lubricating oil through the installation groove 301 is increased, and then by switching the sieve plates A406 and B409 to close and separate at the opening of the installation groove 301, the displacement of the lubricating oil of the rotating parts during the oiling operation is changed, thereby avoiding the waste of lubricating oil caused by excessive oiling and the unstable operation of the rotating parts caused by insufficient lubrication.

[0033] In this embodiment, Figure 2 and Figure 4 As shown, a connecting pipe A9 is connected between the notch 210 and one of the mounting plates 401, and a connecting pipe B901 is connected to the inner wall of the other mounting plate 401, and the opening of the connecting pipe B901 is located above the gear ring 205, and the inner edges and corners of the gear ring 205 are all arc-shaped; a drainage groove A10 is opened on the inner side of the rotating frame 203, and a plurality of drainage grooves B11 are opened on the inner wall of the friction ring 204 near the inner side of the drainage groove A10, and the plurality of drainage grooves B11 are connected to the annular groove B202; a drainage groove A10 is opened on the inner side of the rotating frame 203, and a plurality of drainage grooves B11 are opened on the inner wall of the friction ring 204 near the inner side of the drainage groove A10, and the plurality of drainage grooves B11 are connected to the annular groove B202, and a plurality of slot holes 12 are provided on the inner wall of the connecting seat 206.

[0034] In this embodiment, when the lubricating oil passes through the notch 210, passes through the connection pipe A9 and the installation groove 301, and is discharged from the opening of the connection pipe B901, it will fall on the upper surface of the gear ring 205 under the influence of gravity. Since the inner edges and corners of the gear ring 205 are all arc-shaped, the lubricating oil will continue to flow into the inner side of the rotating frame 203 under the traction of gravity, and the remaining lubricating oil on the surface of the gear ring 205 will flow to the outer edge of the gear ring 205 through the slot 12 with the centrifugal force generated when the gear ring 205 rotates. The outer edge of the gear ring 205 is meshed with the worm 162, and then the lubricating oil on the outer edge of the gear ring 205 can be smoothly applied to the worm 162. 62, thereby completing the oiling work of the gear ring 205 and the worm 162, and the lubricating oil 203 flowing to the inside of the rotating frame 203 will continue to flow into the drainage groove A10 under the traction of gravity, and then smoothly flow into the annular groove A201 under the drainage of the drainage groove A10, and because the drainage groove B11 is in contact with the rotating frame 203 and is connected with the annular groove B202, when the lubricating oil passes through the drainage groove A10, part of the lubricating oil will flow into the drainage groove B11 as the rotating frame 203 rotates, and then under the drainage of the drainage groove B11, the lubricating oil can enter the annular groove B202, thereby completing the oiling work between the rotating parts in the turntable.

[0035] In this embodiment, Figure 1 , Figure 2 and Figure 7 As shown, a feed pipe 13 is arranged between the oil storage barrel 208, the mounting frame 207, the support seat 2 and the inner wall of the mounting seat 1, a one-way valve 14 is arranged at one end of the feed pipe 13 inside the oil storage barrel 208, and a feed end 15 is arranged at the other end of the feed pipe 13 outside the mounting seat 1.

[0036] In the present embodiment, when new lubricating oil needs to be injected into the oil storage barrel 208, the lubricating oil is injected at the feed end 15, and the lubricating oil passes through the feed pipe 13 and the one-way valve 14 to enter the oil storage barrel 208, thereby completing the oil filling work. The one-way valve 14 is provided to prevent the lubricating oil inside the oil storage barrel 208 from flowing back.

[0037] In summary, the working principle of the present invention is as follows: First, when the device is working, the drive motor 161 is started to drive the worm 162 to rotate. When the worm 162 rotates, it meshes with the gear ring 205, so that the gear ring 205 drives the inner wall of the groove A of the rotating frame 203 to rotate. When the lubricating oil between the grooves A of the rotating frame 203 is gradually consumed as the turntable continues to work, the friction between the friction ring 204 and the rotating frame 203 will gradually increase, and then the friction ring 204 will rotate with the rotation of the rotating frame 203. While the friction ring 204 rotates, it will drive the sleeve rod 601 and the top to move synchronously along the outer periphery of the oil storage barrel 208 through the connecting frame 6, and the top rod 602 will move through the connection block 8 and the spiral groove 7. The sliding of the connecting block 8 causes the push rod 602 to move upward along the inner wall of the sleeve rod 601 through the traction of the spiral groove 7, and the push rod 602 will push the clamping ring 214 to rise synchronously when it rises, and due to the sliding between the top of the push rod 602 and the lower surface of the clamping ring 214, the clamping ring 214 will only move vertically up and down, and will not rotate with the movement of the push rod 602, and the clamping ring 214 will drive the baffle A211 to rise synchronously through the L-shaped rod A when it rises, and the baffle A211 will drive the baffle B213 to rise synchronously through the arc rod 212 when it rises, and then expose the notch 210, so that the lubricating oil inside the oil storage barrel 208 can pass through the notch 210 and pass through the connecting pipe A9 and the mounting groove 301, and then flow out of the connecting pipe 9 and the mounting groove 301. The lubricating oil is discharged through the opening of the pipe B901, and then the lubricating oil falls on the upper surface of the gear ring 205 under the influence of gravity. Since the inner edges and corners of the gear ring 205 are all arc-shaped, the lubricating oil will continue to flow into the inner side of the rotating frame 203 under the traction of gravity, and the remaining lubricating oil on the surface of the gear ring 205 will flow to the outer edge of the gear ring 205 through the slot 12 with the centrifugal force generated when the gear ring 205 rotates. The outer edge of the gear ring 205 is meshed with the worm 162, and then the lubricating oil on the outer edge of the gear ring 205 can smoothly smear the surface of the worm 162, thereby completing the oiling work of the gear ring 205 and the worm 162, and the lubricating oil 203 flowing to the inner side of the rotating frame 203 will continue to flow into the drainage groove A10 under the traction of gravity. Then, the lubricating oil flows smoothly into the annular groove A201 under the drainage of the drainage groove A10, and because the drainage groove B11 is in contact with the rotating frame 203 and is connected with the annular groove B202, when the lubricating oil passes through the drainage groove A10, as the rotating frame 203 rotates, part of the lubricating oil flows into the drainage groove B11, and then, under the drainage of the drainage groove B11, the lubricating oil can enter the annular groove B202, thereby completing the oil filling work between the rotating parts of the turntable, so that the turntable can automatically complete the oil filling and lubrication work between the turntable parts through the increase of the friction between the rotating parts, reducing the accelerated wear of the parts caused by the failure to fill the oil and lubricate in time, and eliminating the need for frequent manual inspection and oil filling operations, saving manpower and time costs.And because there is a certain gap at the protrusions at both ends of the snap ring 214, the snap ring 214 will not contact the end of the L-shaped connecting rod B5 when the height changes within a certain range. When the friction between the rotating frame 203 and the friction ring 204 is small, the force of the friction ring 204 during rotation will be small, and then the upper limit of the height of the snap ring 214 is low, so that it cannot contact the end of the L-shaped connecting rod B5. When the friction between the rotating frame 203 and the friction ring 204 is large, the upper limit of the height of the snap ring 214 pushed by the top rod 602 is high, so that the snap ring 214 can drive the L-shaped connecting rod B5 to move upward synchronously, and when the L-shaped connecting rod B5 rises, it will drive one of the push plates 402 to rise synchronously, and then one of the racks 405 will rise synchronously and then mesh with the gear 404, so that the gear 404 rotates, and when the gear 404 rotates, it will cause the other rack 405 to drop, so that the two racks 405 are synchronously driven The two sieve plates A406 are moved to close at the opening of the connecting pipe B901, and the two racks 405 drive the sieve plates to close. At the same time, the two connecting rods 408 drive the two sieve plates B409 to separate in opposite directions through the connecting rod 407. Since the mesh number of the sieve plate A406 is greater than the mesh number of the sieve plate B409, the displacement of the lubricating oil through the installation groove 301 is increased, and then the sieve plates A406 and B409 are switched to close and separate at the opening of the installation groove 301, thereby changing the rotation speed. The displacement of the lubricating oil during the oil filling operation of the moving parts can avoid the waste of lubricating oil caused by excessive oil filling and the unstable operation of the rotating parts caused by insufficient lubrication. When new lubricating oil needs to be injected into the oil storage barrel 208, the lubricating oil is injected into the feed end 15, and the lubricating oil passes through the feed pipe 13 and the one-way valve 14 to allow the lubricating oil to enter the oil storage barrel 208, thereby completing the oil filling work. The one-way valve 14 is used to prevent the lubricating oil in the oil storage barrel 208 from flowing back.
