Description

Technical Field

[0001] The invention belongs to the technical field of lifting platforms, and in particular relates to a hydraulic lifting platform for production and processing with automatic height adjustment. Background Art

[0002] In the production and processing of wind power glass fiber pultruded panels, hydraulic lifting platforms are widely used in various links. For example, in the process of handling and stacking raw materials, the hydraulic lifting platform can lift the raw materials to a suitable height to facilitate workers to operate; in the processes of panel forming and curing, the hydraulic lifting platform can adjust the height of the processing equipment to meet different process requirements;

[0003] In the production and processing of wind power glass fiber pultruded panels, high accuracy of height adjustment is required. However, long-term load action will change the pressure distribution inside the hydraulic rod, resulting in slight elastic deformation of the hydraulic rod. As time accumulates, this elastic deformation may gradually increase, causing the extension length of the hydraulic rod to change, thereby affecting the height position accuracy of the platform. The extension length of the hydraulic rod will change, resulting in deviation of the height position of the platform. At the same time, the sealing components in the hydraulic system may experience wear and aging after long-term use, resulting in hydraulic oil leakage, which leads to unstable pressure in the hydraulic cylinder, thereby affecting the extension length of the hydraulic rod. Even a small leakage may have a significant impact on the height adjustment of the platform during long-term use.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By adding an adjustment and fixing component, through the coordinated use of the fixing sleeve, hinge block, support clamp rod, guide plate, plug block, sliding sleeve, hinge clamp sleeve and sliding column and other structures provided in the component, when it is necessary to lift it to the required processing position, the wind power glass fiber pultruded plate placed on the surface of the loading platform is lifted to the processing position, and the support clamp rod can be stuck in the corresponding card slot, so as to fix the upper position of the lifting platform. When the lifting platform moves to a certain position, the position can be automatically fixed to prevent the position of the lifting platform from changing during long-term lifting. This design plays a significant role in the production and processing of wind power glass fiber pultruded plates and can ensure It can ensure the stability of production operations and ensure that the lifting platform is accurately fixed during the working process, providing strong support for the production of wind power glass fiber pultruded boards. It can ensure that the processing equipment works at a stable height, thereby improving the processing accuracy, reducing the errors caused by the shaking or displacement of the lifting platform, and effectively improving the production efficiency and product quality. At the same time, the automatic fixing function can prevent the lifting platform from accidentally falling or shifting. For example, in the processing of wind power glass fiber pultruded boards, if the lifting platform moves suddenly, it may cause the plate being processed to fall and cause harm to the operator. This fixed structure can effectively avoid the occurrence of such safety accidents.

[0021] When resetting, first move up to release the limit fixation and then retract the hydraulic rod, which is beneficial to protecting the hydraulic system. If the hydraulic rod is forcibly retracted in a fixed state, the hydraulic system will be under greater pressure and resistance, which may cause problems such as hydraulic oil leakage and hydraulic rod deformation. By releasing the fixation first, the resistance of the hydraulic rod when retracting is reduced, which can ensure that the hydraulic system operates within a reasonable working pressure range, extend the service life of the hydraulic system, and reduce maintenance costs.

[0022] 2. By adding a jacking extension component, through the coordinated use of the jack block, loading platform, connecting slider, auxiliary support plate, supporting slide bar, fixed column and guide rod and other structures provided in the component, when the lifting platform moves up, the auxiliary support plate connected to one end of the connecting slide bar can slide from one side of the loading platform to the other side. The sliding out of the auxiliary support plate increases the supporting area of ​​the wind power glass fiber pultruded board and improves the stability of the support. The larger supporting area can lower the center of gravity of the platform, reduce the possibility of platform shaking or tilting, and ensure the safety of operation. After the auxiliary support plate slides out, the overall carrying capacity of the platform is improved. The increase in the supporting area can enable the platform to better disperse the weight it bears. When transporting or processing heavier wind power glass fiber pultruded boards, the platform can bear a larger weight without damage, and can adapt to more types and weights of processing tasks;

[0023] The pulleys provided in combination can avoid direct contact between the auxiliary support plate and the wind power glass fiber pultruded plate to produce friction scratches. When the wind power glass fiber pultruded plate is placed on the loading platform, the pulleys can change the contact mode between the auxiliary support plate and the wind power glass fiber pultruded plate into rolling contact, thereby reducing damage to the surface of the wind power glass fiber pultruded plate and ensuring the appearance quality of the product.

[0024] When the sub-support plate slides out, it can prompt one end of the supporting slide rod fixed on the bottom surface of the sub-support plate to slide along, while the other end of the supporting slide rod can move synchronously to one side on the surface of the guide rod. The supporting slide rod can support the sliding sub-support plate, which can effectively prevent the sub-support plate from excessive deformation or sinking when under the pressure of heavy objects, especially when the sub-support plate is extended to its maximum length. This support can ensure that the sub-support plate remains horizontal and provide reliable support for the objects placed on it. The support on the bottom surface of the sub-support plate helps to improve the carrying capacity of the entire hydraulic lifting platform.

[0025] 3. By adding a tilt warning component, through the coordinated use of the L-shaped connecting rod, horizontal sleeve, vertical rod, measuring plate, abutment ball and measuring ring and other structures provided in the component, when the auxiliary support plate slides out and the other end of the supporting slide rod can move synchronously to one side on the surface of the guide rod, the vertical rod and the horizontal sleeve are prompted to move synchronously. During the process of the loading platform moving up, the staff can observe the relative positions of the measuring plate and the measuring ring on the surface of the vertical rod, so as to intuitively understand the amount of lateral deviation that occurs when the working platform is raised. When lateral deviation occurs, timely maintenance can be carried out to improve the safety of high-altitude operations of the hydraulic lifting platform. If skew occurs, the abutment ball at the bottom of the vertical rod can connect with the touch switch, prompting the alarm device connected to the touch switch to sound an alarm, so that the operator can be informed of the dangerous situation at the first time, and timely alarm can avoid accidents.

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.

[0043] Example: Figure 1-Figure 14 As shown, the present invention provides a technical solution, a hydraulic lifting platform for production and processing with automatic height adjustment, comprising a base 1, a hydraulic rod 11 installed on the surface of the base 1, and a lifting platform 12 installed on the piston end of the hydraulic rod 11;

[0044] The surface of the base 1 is provided with an adjustment fixing assembly 2, which includes a fixing sleeve 21, a card slot 22, a hinge block 23, a support card rod 24, a guide plate 25, a moving block 26, a spring 27, an L-shaped guide rod 28, an L-shaped guide slot 29, an insert block 210, a sliding sleeve 211, a rotating shaft 212, a hinge card sleeve 213 and a sliding column 214;

[0045] A hinge block 23 is fixedly installed on the bottom surface of the lifting platform 12, and a support rod 24 is hinged inside the hinge block 23. A fixing sleeve 21 is installed on the surface of the base 1 and below the support rod 24. A plurality of slots 22 are evenly spaced on the surface of the fixing sleeve 21.

[0046] An L-shaped guide rod 28 is fixedly installed on the inner wall of the fixed sleeve 21, and one end of the L-shaped guide rod 28 is fixedly installed on the surface of the base 1. The surface of the L-shaped guide rod 28 is slidably connected to abut against a moving block 26, and a plurality of plug blocks 210 are fixed at equal intervals on the surface of the moving block 26. In conjunction with a plurality of card slots 22 provided on the surface of the fixed sleeve 21, when the wind power glass fiber pultruded plate is jacked to different required processing positions, the support card rod 24 can be stuck in the corresponding card slot 22, thereby fixing the position of the lifting platform 12 when it moves up to a certain position. When the lifting platform 12 moves up to a certain position, the position can be automatically fixed to prevent the position of the lifting platform 12 from changing due to long-term jacking. This design plays a significant role in the production and processing of wind power glass fiber pultruded plates, can ensure the stability of production operations, ensure that the position of the lifting platform 12 is accurately fixed during operation, provide strong support for the production of wind power glass fiber pultruded plates, and ensure that the processing equipment works at a stable height, thereby improving processing accuracy, reducing errors caused by shaking or displacement of the lifting platform, and effectively improving production efficiency and product quality.

[0047] One end of the support rod 24 is rotatably connected to a rotating shaft 212, one end of the rotating shaft 212 is fixed with a sliding sleeve 211, the bottom surface of the sliding sleeve 211 is fixed with an articulated sleeve 213, a sliding column 214 is hinged inside the articulated sleeve 213, and the surface of the moving block 26 is provided with an L-shaped guide groove 29 adapted to the sliding column 214.

[0048] A guide plate 25 is fixedly mounted on the surface of the base 1 , a sliding sleeve 211 is slidably connected to the surface of the guide plate 25 , a spring 27 is sleeved on the outer surface of the L-shaped guide rod 28 , and one end of the spring 27 abuts against a side surface of the moving block 26 .

[0049] The lifting platform 12 is provided with a lifting extension assembly 3 on its surface, and the lifting extension assembly 3 includes a top block 31, a loading platform 32, a fixed sliding sleeve 33, a fixed sliding rod 34, a connecting sliding block 35, a connecting sliding rod 36, a second spring 37, a secondary support plate 38, a pulley 39, a supporting sliding rod 310, an L-shaped guide sleeve 311, a clearance groove 312, a fixed column 313, a fixed support plate 314 and a guide rod 315;

[0050] A loading platform 32 is arranged above the lifting platform 12, and auxiliary support plates 38 are arranged on both sides of the loading platform 32. A plurality of top blocks 31 are installed on the surface of the lifting platform 12, and a connecting slider 35 is slidably connected in a blind groove provided in the bottom surface of the loading platform 32. A connecting slide bar 36 is slidably connected to the surface of the loading platform 32, one end of the connecting slide bar 36 is connected to the connecting slide bar 35, and the other end of the connecting slide bar 36 is connected to the auxiliary support plate 38. A spring 2 37 is sleeved on the surface of the connecting slide bar 36, one end of the spring 2 37 abuts against the blind groove provided in the bottom surface of the loading platform 32, and the other end of the spring 2 37 is grounded to the connecting slide bar 35. The sliding out of the auxiliary support plate 38 increases the supporting area for the wind power glass fiber pultruded board and improves the stability of the support. A larger supporting area can lower the center of gravity of the platform, reduce the possibility of platform shaking or tilting, and ensure the safety of operation. After the auxiliary support plate 38 slides out, the overall load-bearing capacity of the platform is improved, and the increase in the supporting area can enable the platform to better disperse the weight it bears.

[0051] An L-shaped guide sleeve 311 is fixed to the bottom surface of the connecting slider 35, and a fixed column 313 is slidably connected in the L-shaped groove opened on the surface of the L-shaped guide sleeve 311. The fixed column 313 is fixedly installed in the yield groove 312 opened on the surface of the lifting platform 12. A fixed slide rod 34 is fixed to the bottom surface of the auxiliary support plate 38, and a fixed slide sleeve 33 is slidably provided on the surface of the fixed slide rod 34. The fixed slide sleeve 33 is fixedly installed on the surface of the base 1.

[0052] A pulley 39 is rotatably connected in the groove formed on the surface of the auxiliary support plate 38, a support slide rod 310 is fixed to the bottom surface of the auxiliary support plate 38, and a guide rod 315 is slidably connected to the other end of the support slide rod 310, and a fixed support plate 314 is installed at both ends of the guide rod 315, and the fixed support plate 314 is fixedly installed on the bottom surface of the loading platform 32. The pulley 39 can prevent the auxiliary support plate 38 from directly contacting with the wind power glass fiber pultruded board to produce friction scratches, and when the wind power glass fiber pultruded board is placed on the loading platform 32, the pulley 39 can make the auxiliary support plate 38 and the wind power glass fiber pultruded board have a certain degree of friction between them. The contact mode is changed to rolling contact, which reduces damage to the surface of the wind power glass fiber pultruded board and ensures the appearance quality of the product. The support slide bar 310 can support the sliding sub-branch 38, which can effectively prevent the sub-branch 38 from excessive deformation or sinking when it is under the pressure of heavy objects (such as placing wind power glass fiber pultruded boards). Especially when the sub-branch 38 is extended to the maximum length, this support can ensure that the sub-branch 38 remains horizontal and provides reliable support for the items placed on it. The support on the bottom of the sub-branch 38 helps to improve the carrying capacity of the entire hydraulic lifting platform.

[0053] The bottom surface of the auxiliary support plate 38 is provided with a tilt warning assembly 4, which includes an L-shaped connecting rod 41, a horizontal sleeve 42, a vertical rod 43, a measuring plate 44, an abutment ball 45, a measuring ring 46 and a touch switch 47;

[0054] A vertical rod 43 is fixedly installed on the bottom surface of the auxiliary support plate 38, and a horizontal sleeve 42 is provided on the outer side of the vertical rod 43. A measuring plate 44 is fixedly installed on the surface of the vertical rod 43, and a plurality of measuring rings 46 are provided on the surface of the horizontal sleeve 42. The measuring plate 44 is located above the horizontal sleeve 42. The staff can observe the relative positions of the measuring plate 44 and the measuring ring 46 on the surface of the vertical rod 43, so as to intuitively understand the lateral deviation that occurs when the working platform is raised. When lateral deviation occurs, timely maintenance can be carried out to improve the safety of high-altitude operations of the hydraulic lifting platform.

[0055] An abutment ball 45 is fixedly installed at one end of the vertical rod 43, and a plurality of touch switches 47 are distributed in a ring shape on the outside of the abutment ball 45. The plurality of touch switches 47 are fixedly installed at the bottom of the horizontal sleeve 42. An L-shaped connecting rod 41 is fixedly installed on one side of the horizontal sleeve 42. The other end of the L-shaped connecting rod 41 is fixedly installed on the bottom surface of the supporting slide rod 310. If skew occurs, the abutment ball 45 at the bottom end of the vertical rod 43 can be connected with the touch switch 47, prompting the alarm device connected to the touch switch 47 to sound an alarm, so that the operator can be informed of the dangerous situation at the first time. Timely alarm can avoid accidents.

[0056] The working principle and use process of the present invention are as follows: when the hydraulic lifting platform for production and processing with automatic height adjustment is used, the wind power glass fiber pultruded plate is first hoisted to the surface of the loading platform 32 according to the actual use needs. When it is necessary to lift it to the required processing position, the extension of the piston end of the hydraulic rod 11 is controlled, and then the lifting platform 12 installed at the piston end of the hydraulic rod 11 can be lifted up. As the lifting platform 12 moves up, the top block 31 installed on the surface of the lifting platform 12 can be prompted to contact with the bottom surface of the loading platform 32, and under the action of the top block 31 in the upward state, the loading platform 32 can be prompted to move up, and then the placed The wind power glass fiber pultruded plate on the surface of the loading platform 32 is lifted to the processing position. At the same time, the support clamp rod 24 hinged in the hinge block 23 can deflect around the hinge block 23 under the action of its own weight, and the sliding sleeve 211 connected to one end of the support clamp rod 24 through the rotating shaft 212 can move to one side horizontally under the action of the guide plate 25, so as to enable the sliding column 214 connected to the hinge clamp 213 to slide in the L-shaped guide groove 29 provided on the surface of the moving block 26, so as to enable the moving block 26 to slide to one side on the surface of the L-shaped guide rod 28, and enable the spring sleeved on the surface of the L-shaped guide rod 28 to slide to one side. When the lifting platform 12 is moved to a certain position, the position can be automatically fixed to prevent the position of the lifting platform 12 from changing due to long-term lifting. This design plays a significant role in the production and processing of wind power glass fiber pultruded plates and can ensure the safety of production. The stability of production operation ensures that the lifting platform 12 is accurately fixed in position during the working process, provides strong support for the production of wind power glass fiber pultruded boards, ensures that the processing equipment works at a stable height, thereby improving the processing accuracy, reducing the error caused by the shaking or displacement of the lifting platform, and effectively improving the production efficiency and product quality. At the same time, the automatic fixing function can prevent the lifting platform 12 from accidentally falling or shifting. For example, in the processing of wind power glass fiber pultruded boards, if the lifting platform 12 moves suddenly, it may cause the plate being processed to fall and cause harm to the operator. This fixed structure can effectively avoid the occurrence of such safety accidents;

[0057] When resetting, the piston end of the control hydraulic rod 11 is extended to the limit position, so that the support card rod 24 can slide out from the surface of the last card slot 22, and the slide column 214 slides out from the L-shaped guide groove 29. At this time, the slide column 214 no longer applies a thrust to one side on the moving block 26, and the spring 27 in the compressed state can push the moving block 26 to slide in the opposite direction and slide into the fixed sleeve 21 under its own elasticity. At this time, the multiple plug-in blocks 210 on the surface of the moving block 26 correspond to each other and are inserted into the card slots 22 on the surface of the fixed sleeve 21, so that the surface of the fixed sleeve 21 becomes flat. At this time, the retraction of the piston end of the hydraulic rod 11 can be controlled, and at this time, the card end of the support card rod 24 can be on the surface of the fixed sleeve 21. Slide and reset smoothly to one side, and at this time, the sliding column 214 connected to the hinged sleeve 213 can contact the surface of the moving block 26, causing the sliding column 214 to deflect, ensuring the reset of the supporting clamping rod 24, so as to facilitate the jacking operation on the next side. First move up to release the limit fixation and then retract the hydraulic rod 11, which is beneficial to protect the hydraulic system. If the hydraulic rod 11 is forcibly retracted in a fixed state, the hydraulic system will be subjected to greater pressure and resistance, which may cause hydraulic oil leakage, deformation of the hydraulic rod 11 and other problems. By releasing the fixation first, the resistance of the hydraulic rod 11 when retracting is reduced, which can ensure that the hydraulic system operates within a reasonable working pressure range, extend the service life of the hydraulic system, and reduce maintenance costs.

[0058] When the lifting platform 12 moves upward, the fixed column 313 installed in the yielding groove 312 can also move upward with it, and the fixed column 313 can slide in the L-shaped groove opened on the surface of the L-shaped guide sleeve 311. As the lifting platform 12 moves, when the fixed column 313 is in the L-shaped guide sleeve 311 of the inclined section, the connecting slider 35 can slide to one side in the blind groove opened on the bottom surface of the loading platform 32, and then the connecting slider 35 can push the connecting slide rod 36, and then the auxiliary support plate 38 connected to one end of the connecting slide rod 36 can slide from one side of the loading platform 32 to the other side. When the spring 2 37 is compressed, the sliding out of the auxiliary support plate 38 increases the support area for the wind power glass fiber pultruded board and improves the stability of the support. The larger support area can lower the center of gravity of the platform, reduce the possibility of platform shaking or tilting, and ensure the safety of operation. After the auxiliary support plate 38 slides out, the overall load-bearing capacity of the platform is improved. The increase in the support area can enable the platform to better disperse the weight it bears. When transporting or processing heavier wind power glass fiber pultruded boards, the platform can bear a greater weight without being damaged, and can adapt to more types and weights of processing tasks;

[0059] When the platform is reset, the lifting platform 12 moves downward, causing the fixed column 313 to move downward in the reverse direction in the L-shaped groove provided on the surface of the L-shaped guide sleeve 311, and the second spring 37 in the compressed state can push the connecting slide block 35 to slide in the reverse direction in the blind groove on the bottom surface of the loading platform 32 under the action of its own elasticity, thereby causing the auxiliary support plate 38 to slide in the reverse direction and reset;

[0060] The pulley 39 provided in cooperation can avoid direct contact between the auxiliary support plate 38 and the wind power glass fiber pultruded plate to produce friction scratches. When the wind power glass fiber pultruded plate is placed on the loading platform 32, the pulley 39 can change the contact mode between the auxiliary support plate 38 and the wind power glass fiber pultruded plate into rolling contact, thereby reducing damage to the surface of the wind power glass fiber pultruded plate and ensuring the appearance quality of the product;

[0061] When the stage 32 moves upward, the fixed slide bar 34 installed on the bottom surface of the stage 32 can be pulled out from the fixed slide sleeve 33 to limit and guide the up and down movement of the stage 32, thereby improving the stability of the stage 32 during the up and down movement.

[0062] When the secondary support plate 38 slides out, it can cause one end of the support slide bar 310 fixedly mounted on the bottom surface of the secondary support plate 38 to slide along, and the other end of the support slide bar 310 can move synchronously to one side on the surface of the guide rod 315, and the support slide bar 310 can support the secondary support plate 38 that slides out, which can effectively prevent the secondary support plate 38 from being excessively deformed or sinking when it is subjected to the pressure of heavy objects (such as placing wind power glass fiber pultruded boards). In particular, when the secondary support plate 38 is extended to its maximum length, this support can ensure that the secondary support plate 38 remains horizontal, providing reliable support for the items placed on it, and the support on the bottom surface of the secondary support plate 38 helps to improve the carrying capacity of the entire hydraulic lifting platform;

[0063] When the auxiliary support plate 38 slides out and the other end of the supporting slide bar 310 can move synchronously to one side on the surface of the guide rod 315, the vertical rod 43 installed on the bottom surface of the auxiliary support plate 38 can slide out synchronously, and the L-shaped connecting rod 41 connected to the bottom surface of the supporting slide bar 310 can push the horizontal sleeve 42 to move accordingly, so that the vertical rod 43 moves synchronously with the horizontal sleeve 42. During the upward movement of the loading platform 32, the staff can observe the relative positions of the measuring plate 44 and the measuring ring 46 on the surface of the vertical rod 43, so as to intuitively understand the lateral deviation of the working platform when it is raised. When lateral deviation occurs, timely maintenance can be carried out to improve the safety of high-altitude operations of the hydraulic lifting platform. If skew occurs, the abutment ball 45 at the bottom end of the vertical rod 43 can be in contact with the touch switch 47, prompting the alarm device (not shown in the figure) connected to the touch switch 47 to sound an alarm, so that the operator can be informed of the dangerous situation in the first time, and timely alarm can avoid accidents.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
